Abstract

Background

Reducing perioperative risk is in the focus of primary arthroplasty caregivers. Primary shoulder arthroplasty patients are considered among those with the lowest perioperative risk. Nonetheless, in tertiary care centres and university settings patients with significant comorbidities are being treated. It remains unclear whether the overall comorbidity burden is truly higher and if this results in an increased frequency of adverse events (AE). As a result, we conducted a study to assess the comorbidity burden and the frequency of major perioperative adverse events and predictive factors following primary shoulder arthroplasty in the university setting.

Methods

A retrospective cohort analysis was conducted on patients undergoing primary shoulder arthroplasty for a non-trauma, non-tumour indication from January 1st, 2014 through December 31st, 2018. Administrative data were recorded to assess comorbidity burden and revision surgery within the first postoperative year. Major adverse events were routinely recorded on a weekly basis by the treating physicians. Descriptive and comparative statistical analyses were performed. The cohort was compared against a large North American sample.

Results

Of 386 patients who underwent 400 primary shoulder arthroplasties 14 (3.5 %) experienced adverse events. While AE were distributed equally among anatomical and reverse shoulder arthroplasties, no adverse event was recorded in the 34 hemiarthroplasty patients. The cohort showed an increased comorbidity burden in international comparison. Peptic ulcer disease was significantly associated with AE, while mild liver disease experienced a trend towards AE.

Conclusion

We found an increased comorbidity burden and a low rate of AE for primary shoulder arthroplasty in a tertiary care and university setting. The distinct role of peptic ulcer disease in this cohort and the trend in mild liver disease merit further investigation in larger samples. The findings underscore the importance of perioperative risk assessment and management.

Abstract

Background

This study examined trends in inpatient charges for primary anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA), hemiarthroplasty (HA), and revision total shoulder arthroplasty (revTSA) over the past decade.

Methods

The New York Statewide Planning and Research Cooperative System was queried for patients undergoing primary aTSA, rTSA, HA, and revTSA from 2010 to 2020 using International Classification of Diseases procedure codes. The primary outcome measured was total charges per encounter. Secondary outcomes included accommodation and ancillary charges, charges covered by insurance, and facility volume. Ancillary charges were defined as fees for diagnostic and therapeutic services and accommodation charges were defined as fees associated with room and board. Subgroup analysis was performed to assess differences between high- and low-volume centers.

Results

During the study period, 46,044 shoulder arthroplasty cases were performed: 18,653 aTSA, 4002 HA, 19,253 rTSA, and 4136 revTSA. An exponential increase in rTSA (2428%) and considerable decrease in HA (83.9%) volumes were observed during this period. Total charges were the highest for rTSA and revTSA and the lowest for aTSA. Subgroup analysis of revTSA by indication revealed that total charges were the highest for periprosthetic fractures. For aTSA, rTSA, and HA, high-volume centers achieved significantly lower total charges compared to low-volume centers. Over the study period, total inpatient charges increased by 57.2%, 38.4%, 102.4%, and 68.4% for aTSA, rTSA, HA, and revTSA, outpacing the inflation rate of 18.7%.

Conclusion

Total inpatient charges for all arthroplasty types increased dramatically from 2010 to 2020, outpacing inflation rates, but high-volume centers demonstrated greater success at mitigating charge increases compared to low-volume centers.

Abstract

BACKGROUND

Same-day discharge for shoulder arthroplasty (SA) is well-supported in the literature; however, most studies have focused on healthier patients. Indications for same-day discharge SA have expanded to include patients with more comorbidities, but safety of same-day discharge in this population remains unknown. We sought to compare outcomes following same-day discharge vs. inpatient SA in a cohort of patients considered higher risk for adverse events, defined as an American Society of Anesthesiologists (ASA) classification of ≥3.

METHODS

Data from Kaiser Permanente's SA registry were utilized to conduct a retrospective cohort study. All patients with an ASA classification of ≥3 who underwent primary elective anatomic or reverse SA in a hospital from 2018 to 2020 were included. The exposure of interest was in-hospital length of stay: same-day discharge vs. ≥1-night hospital inpatient stay. The likelihood of 90-day post-discharge events, including emergency department (ED) visit, readmission, cardiac complication, venous thromboembolism, and mortality, was evaluated using propensity score-weighted logistic regression with noninferiority testing using a margin of 1.10.

RESULTS

The cohort included a total of 1814 SA patients, of whom 1005 (55.4%) had same-day discharge. In propensity score-weighted models, same-day discharge was not inferior to an inpatient stay SA regarding 90-day readmission (odds ratio [OR] = 0.64, one-sided 95% upper bound [UB] = 0.89) and overall complications (OR = 0.67, 95% UB = 1.00). We lacked evidence in support of noninferiority for 90-day ED visit (OR = 0.96, 95% UB = 1.18), cardiac event (OR = 0.68, 95% UB = 1.11), or venous thromboembolism (OR = 0.91, 95% UB = 2.15). Infections, revisions for instability, and mortality were too rare to evaluate using regression analysis.

CONCLUSIONS

In a cohort of over 1800 patients with an ASA of ≥3, we found same-day discharge SA did not increase the likelihood of ED visits, readmissions, or complications compared with an inpatient stay, and same-day discharge was not inferior to an inpatient stay with regard to readmissions and overall complications. These findings suggest that it is possible to expand indications for same-day discharge SA in the hospital setting.

Abstract

Purpose

The purposes of this study were to investigate the difference in value (benefit to cost ratio) of dermal allograft superior capsular reconstruction (SCR) versus reverse total shoulder arthroplasty (rTSA) for the treatment of massive rotator cuff tears (MRCTs) without arthritis; to compare the patient populations selected for the operations and report pre- and postoperative functional data; and to understand other characteristics of the 2 operations, including operating time, use of institutional resources, and complications.

Methods

A retrospective, single-institution analysis during the study period 2014-2019 with MRCT treated with SCR or rTSA by 2 surgeons with complete institutional cost data and minimum 1-year clinical follow-up with American Shoulder and Elbow Surgeons (ASES) score. Value was defined as ΔASES/(total direct costs/$10,000).

Results

Thirty patients underwent rTSA and 126 patients SCR during the study period with significant differences noted in patient demographics and tear characteristics between the groups (patients who underwent rTSA were older, less male, had more pseudoparalysis, had greater Hamada and Goutallier scores, and had more proximal humeral migration). Value was 25 and 29 (ΔASES/$10,000) for rTSA and SCR, respectively (P = .7). The total costs of rTSA and SCR were $16,337 and $12,763, respectively (P = .7). Both groups experienced substantial improvements in ASES scores: 42 for rTSA vs 37 for SCR (P = .6). The operative time for SCR was much longer (204 vs 108 minutes, P < .001) but complication rate lower (3% vs 13%, P = .02) versus rTSA.

Conclusions

In a single institutional analysis of the treatment of MRCT without arthritis, rTSA and SCR demonstrated similar value; however, the value calculation is highly dependent on institution specific variables and duration of follow-up. The operating surgeons demonstrated different indications in selecting patients for each operation. rTSA had an advantage over SCR in shorter operative time, whereas SCR demonstrated a lower complication rate. Both SCR and rTSA are demonstrated to be effective treatments for MRCT at short-term follow-up.

Is Advanced Imaging to Assess Rotator Cuff Integrity Before Shoulder Arthroplasty Cost-effective? A Decision Modeling Study. Clin Orthop Relat Res 2022;480:1129-1139.

Abstract

BACKGROUND

Shoulder arthroplasty is increasingly performed for patients with symptoms of glenohumeral arthritis. Advanced imaging may be used to assess the integrity of the rotator cuff preoperatively because a deficient rotator cuff may be an indication for reverse shoulder arthroplasty (RSA) rather than anatomic total shoulder arthroplasty (TSA). However, the cost-effectiveness of advanced imaging in this setting has not been analyzed.

QUESTIONS/PURPOSES

In this cost-effectiveness modeling study of TSA, all patients underwent history and physical examination, radiography, and CT, and we compared (1) no further advanced imaging, (2) selective MRI, (3) MRI for all, (4) selective ultrasound, and (5) ultrasound for all.

METHODS

A simple chain decision model was constructed with a base-case 65-year-old patient with a 7% probability of a large-to-massive rotator cuff tear and a follow-up of 5 years. Strategies were compared using the incremental cost-effectiveness ratio (ICER) with a willingness to pay of both USD 50,000 and 100,000 per quality-adjusted life year (QALY) used, in accordance with the Second Panel on Cost-Effectiveness in Health and Medicine. Diagnostic test sensitivity and specificity were extracted from published systematic reviews and meta-analyses, and patient utilities were obtained using the Cost-Effectiveness Analysis Registry from the Center for the Evaluation of Value and Risk in Health. Final patient states were categorized as either inappropriate or appropriate based on the actual rotator cuff integrity and type of arthroplasty performed. Additionally, to evaluate the real-world impact of intraoperative determination of rotator cuff status, a secondary analysis was performed where all patients indicated for TSA underwent intraoperative rotator cuff examination to determine appropriate implant selection.

RESULTS

Selective MRI (ICER of USD 40,964) and MRI for all (ICER of USD 79,182/QALY) were the most cost-effective advanced imaging strategies at a willingness to pay (WTP) of USD 50,000/QALY gained and 100,000/QALY gained, respectively. Overall, quality-adjusted life years gained by advanced soft tissue imaging were minimal: 0.04 quality-adjusted life years gained for MRI for all. Secondary analysis accounting for the ability of the surgeon to alter the treatment plan based on intraoperative rotator cuff evaluation resulted in the no further advanced imaging strategy as the dominant strategy as it was the least costly (USD 23,038 ± 2259) and achieved the greatest health utility (0.99 ± 0.05). The sensitivity analysis found the original model was the most sensitive to the probability of a rotator cuff tear in the population, with the value of advanced imaging increasing as the prevalence increased (rotator cuff tear prevalence greater than 12% makes MRI for all cost-effective at a WTP of USD 50,000/QALY).

CONCLUSION

In the case of diagnostic ambiguity based on physical exam, radiographs, and CT alone, having both TSA and RSA available in the operating room appears more cost-effective than obtaining advanced soft tissue imaging preoperatively. However, performing selective MRI to assess rotator cuff integrity to indicate RSA or TSA is cost-effective if surgical preparedness, patient expectations, and implant availability preclude the ability to switch implants intraoperatively.

Abstract

Background:

The rate of retear after primary rotator cuff failure remains unacceptably high (up to 36% for small- to medium-sized tears). Augmentation of cuff repair with scaffold devices has been reported to improve healing after cuff repair.

Purpose/Hypothesis:

To describe the surgical technique of using an interpositional nanofiber scaffold during rotator cuff repair and report on a retrospective series of patients regarding functional outcomes and postoperative healing on magnetic resonance imaging (MRI). We hypothesized that augmentation of cuff repair with an interpositional scaffold would result in a high rate of tendon healing and excellent functional outcomes.

Study Design:

Case series; Level of evidence, 4.

Methods:

A total of 33 patients underwent arthroscopic rotator cuff repair augmented with a nanofiber, bioresorbable polymer patch secured as an inlay between the tendon and underlying bone. Patients were evaluated preoperatively and postoperatively with the Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons (ASES) shoulder score, and active range of motion (ROM) measurements. Postoperative MRI was used to evaluate repair status.

Results:

At a minimum follow-up of 6 months, the patients showed significant improvement on SST and ASES scores (P < .0001 for both). ROM in forward flexion, abduction, internal rotation, and external rotation significantly improved at 6 months postoperatively (P < .05 for all). MRI at an average of 11 months postoperatively showed healing in 91% of patients; one patient had a recurrent tear with transtendon failure, and another patient had retear at the insertional site. The patch was not visible on postoperative imaging, suggesting complete resorption in all patients. No adverse events were associated with the patch.

Conclusion:

Our results demonstrate the preliminary safety and efficacy of a novel, bioresorbable synthetic scaffold for rotator cuff repair. The use of the scaffold resulted in a 91% tendon healing rate and significant improvements in functional and patient-reported outcome measures. The results are promising for improving the current unacceptably high rate of rotator cuff repair failure.

Abstract

BACKGROUND

With increasing emphasis on value-based care and the heavy demands on the US health care budget, surgeons must be cognizant of factors that drive cost and quality of patient care. Our objective was to determine patient-level drivers of lower costs and improved health-related quality of life (HRQoL) in 2 anatomic shoulder arthroplasty procedures: total shoulder arthroplasty (TSA) and ream-and-run arthroplasty.

METHODS

This study included 222 TSAs and 211 ream-and-run arthroplasties. Simple Shoulder Test, Single Assessment Numeric Evaluation, and Short Form 36 scores were collected preoperatively and 2 years postoperatively. Quality-adjusted life-years (QALYs) were calculated as a measure of HRQoL. Univariate and multivariate analyses determined factors significantly associated with decreased hospitalization costs and improved HRQoL.

RESULTS

In the TSA group, female sex, lower American Society of Anesthesiologists class, diagnosis other than capsulorrhaphy arthropathy, lower pain score, and higher Single Assessment Numeric Evaluation score were associated with decreased total hospitalization costs; in addition, female sex was an independent predictor of lower total costs. Insurance other than workers' compensation, a diagnosis of chondrolysis, and higher optimism led to greater QALY gains, but a diagnosis of capsulorrhaphy arthropathy was the only independent predictor of greater QALY gains. In the ream-and-run arthroplasty group, older age, lower body mass index (BMI), lower American Society of Anesthesiologists class, insurance other than Medicaid, diagnosis other than capsulorrhaphy arthropathy, no history of surgery, higher preoperative Simple Shoulder Test score, and higher preoperative Short Form 36 Physical Component Summary score were associated with lower total costs; moreover, lower BMI was an independent predictor of lower costs. Higher preoperative optimism was an independent predictor of greater QALY gains.

CONCLUSIONS

Identifying factors associated with decreased costs and increased quality is becoming increasingly important in value-based care. This study identified fixed (sex and diagnosis) and modifiable (BMI) factors that drive decreased hospitalization costs and increased HRQoL improvements in shoulder arthroplasty patients. Higher preoperative patient optimism is a consistent predictor of improved HRQoL for both TSA patients and ream-and-run arthroplasty patients, and further study on optimizing the influence of patient expectations and optimism may be warranted.

Abstract

BACKGROUND

While anatomic total shoulder arthroplasty (TSA) has historically been considered the ideal treatment for end-stage glenohumeral osteoarthritis, reverse shoulder arthroplasty (RSA) has recently gained popularity. With substantial differences in implant design and cost between TSA and RSA, further investigation of outcomes and value is needed to support recent trends. The purpose of this study was to use the average and incremental cost-effectiveness ratio (ACER and ICER) and the procedure value index (PVI) to examine differences in outcomes and value between TSA and RSA for treatment of glenohumeral osteoarthritis with an intact rotator cuff.

METHODS

We performed a retrospective matched-cohort study of patients treated with primary shoulder arthroplasty for osteoarthritis with an intact rotator cuff who had a minimum 2-year follow-up. Outcome measures analyzed included the Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons (ASES) questionnaire, visual analog scale (VAS) for pain, Single Assessment Numeric Evaluation (SANE), and overall satisfaction. Patients treated with TSA were matched 4:1 to those treated with RSA based on sex, age, and preoperative SST score. Value differences between TSA and RSA were calculated. Radiographs were analyzed for preoperative glenoid classification and postoperative radiolucent lines and gross loosening.

RESULTS

Two hundred and fifty-two TSA-treated patients were matched to 63 RSA-treated patients with no significant differences in sex, age, or preoperative SST score. Total hospitalization costs, charges, and reimbursements along with outcome improvements in units of minimal clinically important differences (MCIDs) and patient satisfaction did not differ between the groups. For RSA, the implant cost was significantly higher than that for TSA, but the operating room, anesthesia, and cement costs were lower. The TSA group had a 3.2% rate of gross glenoid loosening and a 2.4% revision rate. There was no loosening or revision in the RSA group. None of the value analytics differed between groups even after inclusion of the outcomes and costs of early TSA revisions.

CONCLUSIONS

TSA and RSA demonstrated similar outcomes and value when used to manage glenohumeral osteoarthritis with an intact rotator cuff.

Abstract

BACKGROUND

Paralleling the increased utilization of shoulder arthroplasty, bundled-payment reimbursement is becoming increasingly common. An understanding of the costs of each element of care and detailed information on the frequency of and reasons for readmission and reoperation are keys to developing bundled-payment initiatives. The purpose of this study was to perform a comprehensive analysis of complications, readmission rates, and costs of primary shoulder arthroplasty at a high-volume institution.

METHODS

Between 2012 and 2016, 2 shoulder surgeons from a single institution performed 1794 consecutive primary shoulder arthroplasties: 636 anatomic total shoulder arthroplasties (TSAs), 1081 reverse shoulder arthroplasties (RSAs), and 77 hemiarthroplasties. A cost analysis was designed to include a period of 60 days preoperatively, the index surgical hospitalization, and 90 days postoperatively, including costs of any readmission or reoperation.

RESULTS

The 90-day complication, reoperation, and readmission rates were 2.3%, 0.6%, and 1.8%, respectively. The 90-day readmission risk was higher among patients with an American Society of Anesthesiologists score of 3 or greater; a 1-unit increase in the American Society of Anesthesiologists score was associated with a $429 increase in index cost. Of the hospital readmissions, 10 were directly related to the index arthroplasty whereas 21 were not. The median standardized costs were as follows: preoperative evaluation, $481; index surgical hospitalization, $15,758; and postoperative care, $183. The median standardized costs for index surgical hospitalization were different for each procedure: TSA, $14,010; RSA, $16,741; and hemiarthroplasty, $12,709.

CONCLUSION

In this study, primary shoulder arthroplasty was associated with low 90-day reoperation and complication rates. The median standardized costs inclusive of preoperative workup and 90-day postoperative recovery were $14,675 and $17,407 for TSA and RSA, respectively.

Abstract

Although reverse total shoulder arthroplasty (RTSA) may outperform hemiarthroplasty (HSA) for acute proximal humerus fractures (PHF), both the RTSA implant and the procedure are more expensive. The goal of this study was to compare the use and longitudinal cost of care for RTSA vs HSA for the treatment of PHF. Patients were selected from a private payer database with a surgical date between 2010 and 2015. The International Classification of Diseases, 9th Revision, Clinical Modification(ICD-9-CM), codes were used to identify patients who underwent RTSA and HSA for PHF. The 1-year cost follow-up was guaranteed. During the study period, a total of 1038 patients underwent RTSA and 1046 patients underwent HSA for the treatment of PHF. A total of 601 patients who underwent RTSA and 431 patients who underwent HSA with at least 1 year of follow-up were matched by age and sex. The average Charlson Comorbidity Index for the RTSA and HSA groups was 4, indicating similar health status. From 2010 to 2015, the use of RTSA increased linearly (R²=0.986), whereas the use of HSA decreased linearly (R²=0.796). The average index admission cost was higher for RTSA than for HSA ($15,263 vs $14,356, respectively; mean difference [MD], $907; 95% confidence interval [CI], $58-$1760; P=.04). At 1 year postoperatively, however, no statistically significant difference was noted in cost (P=.535). The 1-year physical and occupational therapy cost per patient was higher after HSA than after RTSA (MD, $723; CI, $718-$728; P<.001), but no difference was noted in discharge disposition or 1-year revision or readmission rates. The results of this study suggest that despite the higher initial cost of RTSA, the total cost of care in the year after RTSA and HSA is similar. Therefore, RTSA should be considered in the appropriate clinical setting. [Orthopedics. 2020;43(2):119-125.].

Abstract

BACKGROUND

Reverse total shoulder arthroplasty (RSA) accounts for nearly one-third of shoulder arthroplasty utilization nationally. The complication rate has increased concurrently. Consensus is lacking regarding the incidence, etiology, and treatment of acromial or scapular spine fractures after RSA. The purpose of our study was to perform a systematic review of the literature to analyze the occurrence and outcomes of this complication.

METHODS

The MEDLINE, Embase, Google Scholar, and Cochrane databases were queried in late 2017 for combinations of the words "acromial," "fracture," "reverse," "shoulder," and "arthroplasty." We included all studies that contained a clearly defined performance of RSA, acromial fracture(s) noted, and treatment (if any) and outcomes of treatment. The initial search yielded 50 studies; 32 met the inclusion criteria.

RESULTS

Among 3838 RSAs, 159 acromial fractures were reported, for an overall incidence of 4.14%; the mean time to diagnosis from surgery was 9 months (range, 1.3-24 months). Treatments included nonoperative treatment in a sling or abduction brace in 139 cases and open reduction-internal fixation in 20. Regardless of treatment, patients reported inferior function after fracture compared with initially after RSA. Forward flexion was 95° (range, 30°-110°), abduction was 76° (range, 30°-180°), the Constant score was 63 (range, 59-67.5), and the American Shoulder and Elbow Surgeons score was 57 (range, 7-83); all values were reduced compared with patients without fractures.

CONCLUSION

This study suggests the occurrence of acromial fractures after RSA is a common event, with a rate of over 4%. These fractures correlate with worse postoperative outcomes regardless of treatment method; open reduction-internal fixation was not shown to be clinically superior despite a limited complication rate. Additional high-quality studies addressing acromial spine fracture after RSA are needed.

Abstract

BACKGROUND

The Centers for Medicare & Medicaid Services Bundled Payments for Care Improvement (BPCI) initiative was implemented as part of the Affordable Care Act. We implemented a retrospective payment model 2 for a 90-day total shoulder arthroplasty (TSA) episode to assess the value of TSA BPCI at our private practice.

METHODS

Expenditures and postacute event rates of 132 fee-for-service (FFS) patients who underwent a TSA operation between 2009 and 2012 were compared with 333 BPCI patients who had a TSA operation in 2015. The 90-day postacute events included an inpatient rehabilitation facility (IRF), skilled nursing facility (SNF), and home health (HH) admissions and readmissions. Expenditures were converted to 2016 dollars using the Consumer Price Index. Wilcoxon tests and multivariate generalized estimating equation were used to assess independent cost-drivers.

RESULTS

The median FFS expenditure was $21,157 (interquartile range, $16,894-$30,748) compared with $17,894 (interquartile range, $15,796-$20,894) for BPCI (P < .0001). The BPCI patients had significantly lower rates of SNF admissions (34% FFS vs. 16% BPCI; P < .001), IRF admissions (3% FFS vs. 0.6% BPCI; P = .05), HH utilization (49% FFS vs. 41% BPCI; P = .05), and readmissions (14% FFS vs. 7% BPCI; P = .01). After controlling for postacute events in the multivariate regression model, we found BPCI had a 4% decrease in expenditures (P = .08). All postacute events were independently associated with higher expenditures.

CONCLUSIONS

Our private practice implemented cost-containment practices, including clinical guidelines, patient navigators, and a BPCI management team. IRF and SNF utilization and the 90-day readmission rate significantly decreased. As a result, we were able to control the postacute spending, which resulted in decreased costs of performing TSA surgery.

Abstract

BACKGROUND

The purpose of this study was to evaluate the effect of common medical comorbidities on the reimbursements of different shoulder arthroplasty procedures.

METHODS

We conducted a retrospective query of a single private payer insurance claims database using PearlDiver (Warsaw, IN, USA) from 2010 to 2014. Our search included the Current Procedural Terminology codes and International Classification of Diseases, Ninth Revision codes for total shoulder arthroplasty (TSA), hemiarthroplasty, and reverse shoulder arthroplasty (RSA). Medical comorbidities were also searched for through International Classification of Diseases codes. The comorbidities selected for analysis were obesity, morbid obesity, hypertension, smoking, diabetes mellitus, hyperlipidemia, atrial fibrillation, chronic obstructive pulmonary disease, cirrhosis, depression, and chronic kidney disease (excluding end-stage renal disease). The reimbursement charges of the day of surgery, 90-day global period, and 90-day period excluding the initial surgical day of each comorbidity were analyzed and compared. Statistical analysis was conducted through analyses of variance or Kruskal-Wallis test.

RESULTS

Comorbidities did not have a significant effect on same-day reimbursements but instead caused a significant effect on the subsequent 89-day (interval) and 90-day reimbursements in the TSA and RSA cohorts. For TSA and RSA, the highest reimbursement costs during the 90-day period after surgery were seen with the diagnosis of hepatitis C, followed by atrial fibrillation and later chronic obstructive pulmonary disease. For hemiarthroplasty, the same was true in the following order: hepatitis C, cirrhosis, and atrial fibrillation.

CONCLUSION

Shoulder arthroplasty reimbursements are significantly affected by comorbidities at time intervals following the initial surgical day.

Abstract

PURPOSE

To determine the most cost-effective treatment strategy for patients with massive rotator cuff tears and pseudoparalysis of the shoulder without osteoarthritis of the glenohumeral joint (PP without OA). Specifically, we aimed to compare arthroscopic rotator cuff repair (ARCR) versus reverse total shoulder arthroplasty (RTSA) and investigate the effect of patient age on this decision.

METHODS

A Markov decision model was used to compare 3 treatment strategies for addressing PP without OA: (1) ARCR with option to arthroscopically revise once, (2) ARCR with immediate conversion to RTSA on potential failure, and (3) primary RTSA. Hypothetical patients were cycled through the model according to transition probabilities, meanwhile accruing financial costs, utility for time in health states, and disutilities for surgical procedures. Utilities were derived from the Short Form-6D scale and expressed as quality-adjusted life-years. Model parameters were derived from the literature and from expert opinion, and thorough sensitivity analyses were conducted. TreeAge Pro 2015 software was used to construct and assess the Markov model.

RESULTS

For the base-case scenario (60-year-old patient), ARCR with conversion to RTSA on potential failure was the most cost-effective strategy when we assumed equal utility for the ARCR and RTSA health states. Primary RTSA became cost-effective when the utility of RTSA exceeded that of ARCR by 0.04 quality-adjusted life-years per year. Age at decision did not substantially change this result.

CONCLUSIONS

Primary ARCR with conversion to RTSA on potential failure was found to be the most cost-effective strategy for PP without OA. This result was independent of age. Primary ARCR with revision ARCR on potential failure was a less cost-effective strategy.

Abstract

PURPOSE

To compare the cost-effectiveness within the United States health care system of arthroscopic rotator cuff repair versus reverse total shoulder arthroplasty in patients with symptomatic large and massive rotator cuff tears without cuff-tear arthropathy.

METHODS

An expected-value decision analysis was constructed comparing the costs and outcomes of patients undergoing arthroscopic rotator cuff repair and reverse total shoulder arthroplasty for large and massive rotator cuff tears (and excluding cases of cuff-tear arthropathy). Comprehensive literature search provided input data to extrapolate costs and health utility states for these outcomes. The primary outcome assessed was that of incremental cost-effectiveness ratio (ICER) of reverse total shoulder arthroplasty versus rotator cuff repair.

RESULTS

For the base case, both arthroscopic rotator cuff repair and reverse total shoulder were superior to nonoperative care, with an ICER of $15,500/quality-adjusted life year (QALY) and $37,400/QALY, respectively. Arthroscopic rotator cuff repair was dominant over primary reverse total shoulder arthroplasty, with lower costs and slightly improved clinical outcomes. Arthroscopic rotator cuff repair was the preferred strategy as long as the lifetime progression rate from retear to end-stage cuff-tear arthropathy was less than 89%. However, when the model was modified to account for worse outcomes when reverse shoulder arthroplasty was performed after a failed attempted rotator cuff repair, primary reverse total shoulder had superior outcomes with an ICER of $90,000/QALY.

CONCLUSIONS

Arthroscopic rotator cuff repair-despite high rates of tendon retearing-for patients with large and massive rotator cuff tears may be a more cost-effective initial treatment strategy when compared with primary reverse total shoulder arthroplasty and when assuming no detrimental impact of previous surgery on outcomes after arthroplasty. Clinical judgment should still be prioritized when formulating treatment plans for these patients. LEVEL OF EVIDENCE: Level II, economic decision analysis.

Abstract

BACKGROUND

Increased length of hospital stay, hospital readmission, and revision surgery are adverse outcomes that increase the cost of elective orthopaedic procedures, such as shoulder arthroplasty. Awareness of the factors related to these adverse outcomes will help surgeons and medical centers design strategies for minimizing their occurrence and for managing their associated costs.

METHODS

We analyzed data from the New York Statewide Planning and Research Cooperative System on 17,311 primary shoulder arthroplasties performed from 1998 to 2011 to identify factors associated with extended lengths of hospitalization after surgery, readmission within ninety days, and surgical revision.

RESULTS

The factors associated with each of these three adverse outcomes were different. Longer lengths of hospital stay were associated with female sex, advanced patient age, Medicaid insurance, comorbidities, fracture as the diagnosis for arthroplasty, higher hospital case volumes, and lower surgeon case volumes. Readmission was associated with advanced patient age and medical comorbidities. The most common diagnoses for readmission within ninety days were fluid and electrolyte imbalance (28%), acute pulmonary problems (21%), cardiac arrhythmia (20%), heart failure (15%), acute myocardial infarction (10%), and urinary tract infection (10%). Revision was associated with younger patient age and osteoarthritis or traumatic arthritis. The most common diagnoses at the time of revision surgery were unspecified mechanical complications of the implant (60%), shoulder pain (18%), dislocation of the prosthetic joint (12%), component loosening (10%), a broken prosthesis (8%), a cuff tear (7%), and infection (7%).

CONCLUSIONS

A small number of easily identified characteristics (sex, age, race, insurance type, comorbidities, diagnosis, and provider case volumes) were significantly associated with longer lengths of stay, readmission, and revision surgery. Consideration of these factors and their effects may guide efforts to improve patient safety and to manage the costs associated with these adverse outcomes.

Abstract

BACKGROUND

The rate of shoulder arthroplasty has continued to increase at an exponential rate during the past decade in large part owing to approval by the Food and Drug Administration of reverse shoulder arthroplasty. Whereas reverse shoulder arthroplasty has resulted in expanded surgical indications, there are numerous reports of relatively high complication rates. The increased prevalence of both anatomic and reverse shoulder arthroplasty underscores the need to elucidate whether perioperative outcomes are influenced by type of total shoulder arthroplasty. The purpose of this study was to determine the impact of shoulder arthroplasty type, anatomic or reverse, with respect to perioperative adverse events, in-hospital death, prolonged hospital stay, nonroutine disposition, and hospital charges in a nationally representative sample.

METHODS

By use of the Nationwide Inpatient Sample database from 2011, the first year that reverse total shoulder arthroplasty received a unique International Classification of Diseases, Ninth Revision procedure code, an estimated 51,052 patients undergoing total shoulder arthroplasty were separated into anatomic total shoulder arthroplasty (58%) and reverse total shoulder arthroplasty (43%). Comparisons of early outcome measures between anatomic and reverse total shoulder cohorts were performed by bivariate and multivariable analyses with logistic regression modeling.

RESULTS

Compared with anatomic shoulder arthroplasty recipients, patients undergoing reverse shoulder replacement were at higher risk for in-hospital death, multiple perioperative complications, prolonged hospital stay, increased hospital cost, and nonroutine discharge.

CONCLUSION

Despite the expanding indications for reverse shoulder arthroplasty, it is an independent risk factor for inpatient morbidity, mortality, and hospital costs and should perhaps be offered more judiciously and performed in the hands of appropriately trained shoulder specialists.

Abstract

BACKGROUND

Data directly comparing the perioperative complication rates between total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA) are limited.

METHODS

The Nationwide Inpatient Sample database, which comprises data from a statistically representative sample of hospitals across the United States, was analyzed for the years 2010 and 2011. The International Classification of Diseases, Ninth Revision procedure codes differentiated the patients who received TSA (81.80) and RTSA (81.88). Demographic data, comorbidities, perioperative complications, and hospitalization data were compared.

RESULTS

This retrospective analysis included 19,497 patients, with 14,031 patients in the TSA group and 5466 patients in the RTSA group. Patients who underwent RTSA were older (P < .001), were more likely to be female (P < .001), and had increased rates of fracture (P < .001). The RTSA group had significantly higher perioperative rates of mortality (P = .004), pneumonia (P < .001), deep venous thrombosis (P < .001), myocardial infarction (P = .005), urinary tract infection (P < .001), and blood transfusions (P < .001). In addition, the RTSA patients had longer hospital stays (P < .001) and higher hospital charges (P < .001). The rates of comorbidities were also higher in the patients who underwent RTSA. After adjustment for these differences in comorbidities and surgical indications with our multivariate analysis, RTSA was still independently associated with increased hospital charges (difference of $11,530; P < .001), longer hospitalization (difference of 0.24 day; P < .001), more blood transfusions (relative risk, 1.43; P < .001) and higher rates of pneumonia (relative risk, 1.61; P = .04) and deep venous thrombosis (relative risk, 2.24; P = .01).

CONCLUSION

We found that RTSA patients, compared with TSA patients, had significantly longer length of stay, higher hospital charges that are not completely attributable to increased implant costs alone, and increased rates of perioperative complications.

Abstract

BACKGROUND

Complication rates after reverse total shoulder arthroplasty (RTSA) have, in previous series, been reported to be high. The purpose of this study was to describe the complication rates, types, timing, and risk factors after revision RTSA, as compared with primary RTSA.

METHODS

We performed a retrospective review of patients who underwent primary or revision RTSA to determine early (within 90 days) complication rates. Complications were subdivided into medical versus surgical and minor versus major.

RESULTS

One hundred thirty-seven patients met the inclusion criteria. Of these, 111 underwent primary RTSA and 26 underwent RTSA as a revision from a previous arthroplasty. The overall complication rates were 25% after primary RTSA and 69% after revision RTSA. Minor complications accounted for 80% of the complications after primary RTSA and 94% after revision RTSA. Surgical complications were more frequent than medical complications in revision patients, occurring in 18% of primary cases and 62% of revisions. Revision patients more frequently required transfusions, with rates of 5% and 31% for primary cases and revisions, respectively. Overall, minor, surgical, intraoperative, perioperative, and postoperative complications were all significantly more frequent after revision RTSA. Multivariate logistic regression showed that revision status was the most significant predictor of overall (P < .001), minor (P < .001), surgical (P < .001), intraoperative (P = .002), and postoperative (P < .001) complication rates. Medical complications were predicted by body mass index (P < .001).

CONCLUSION

Revision RTSA has a significantly higher rate of complications than primary RTSA. These patients are significantly more likely to require transfusions. Patients should be aware that minor complications are frequent after revision RTSA and should be counseled accordingly.

Abstract

BACKGROUND

The rising number of morbidly obese patients has important consequences for the health-care system. We investigated the effect of morbid obesity on outcomes, complications, discharge disposition, and costs in patients undergoing reverse shoulder arthroplasty.

METHODS

Our joint registry was searched for all patients who had undergone primary reverse shoulder arthroplasty for a reason other than fracture from 2003 to 2010 and had a minimum of twenty-four months of follow-up. Twenty-one patients with a body mass index (BMI) of ≥40 kg/m² were identified (follow-up, 45 ± 16 months; sex, seventeen female and four male; age, 69 ± 7 years) and were compared with sixty-three matched control patients with a BMI of <30 kg/m² (follow-up, 48 ± 20 months; sex, fifty female and thirteen male; age, 71 ± 6 years) after an a priori sample size calculation. Outcome instrument data were obtained preoperatively and postoperatively. The Charlson-Deyo comorbidity index (CDI) score, total comorbidities, operative time, blood loss, duration of hospital stay, discharge disposition, costs, and complications were recorded.

RESULTS

Compared with nonobese patients, morbidly obese patients had similar improvements in functional outcomes (e.g., American Shoulder and Elbow Surgeons score, 32 to 69 compared with 40 to 78) and in shoulder motion (e.g., forward flexion, 61° to 140° compared with 74° to 153°); all improvements were significant (p < 0.05). Morbidly obese patients had a similar rate of scapular notching (odds ratio [OR] = 0.58, p = 0.63), more total comorbidities excluding obesity (six compared with four, p = 0.001), a higher CDI (2 compared with 1, p = 0.025), and a higher rate of obstructive sleep apnea (OR = 27.7, p = 0.0001). Their operative time was thirteen minutes longer (p = 0.014) and their blood loss was 40 mL greater (p = 0.008). Morbidly obese patients had a similar duration of stay (3.1 compared with 2.6 days, p = 0.823) and hospital readmission rate (OR = 16.3, p = 0.08) but a sixfold higher rate of discharge to rehabilitation facilities rather than to home (OR = 8, p < 0.0001). Hospital costs were higher by $2974 (p = 0.009). The rates of major complications (n = 4 compared with 8, p = 0.479) and of minor complications (n = 3 compared with 14, p = 0.440) were similar. No intraoperative complications or mechanical device failures were noted in either group.

CONCLUSIONS

Reverse shoulder arthroplasty appears to be as safe and effective in morbidly obese patients, although it has an increased cost and patients have a lower rate of discharge to home and greater care needs after discharge.
