Application of comprehensive geriatric assessment in oncology nursing: A literature review on optimizing treatment decisions and patient outcomes

Table 4 Comparative studies on comprehensive geriatric assessment vs standard care in oncology nursing

Study	Country/region	Key findings	Cancer types studied	Outcomes measured
French OGS tool	France	Developed and validated a short decision-making algorithm-OGS with high sensitivity to identify frail patients requiring CGA, optimizing treatment decisions	Various cancers	Identification of frail patients, treatment decision-making[18]
CGA in older cancer patients	United States	Meta-analysis of 28 trials (4959 subjects) showed CGA effectively identifies patients benefiting from geriatric evaluation, reducing morbidity and improving physical and cognitive function	Various cancers	Morbidity reduction, physical and cognitive function improvement[23,59]
CGA in cancer care	Australia	Integrating CGA into oncology care improved treatment completion rates, reduced grade 3+ chemotherapy toxicity, and enhanced quality of life scores	Various cancers	Treatment completion rates, chemotherapy toxicity, quality of life scores[27]
Geriatrician-delivered CGA impact	United Kingdom	Demonstrated that geriatrician-led CGA is associated with better outcomes for older patients undergoing chemotherapy compared to standard care	Various cancers	Treatment tolerance, overall survival[63]
CGA predicting overall survival	Singapore	CGA predicted overall survival in patients aged ≥ 70 with solid tumors, aiding in personalized treatment plans	Solid tumors	Overall survival prediction[23]
CGA in primary care	Netherlands	CGA adapted for primary care did not reduce emergency visits but provided insights into patient needs, suggesting areas for care improvement	Various cancers	Emergency department visits, care planning[64]
