Is burnout a mediating factor between sharps injury and work-related factors or musculoskeletal pain?

Figure 1 Mediation effects of high personal burnout level/high work-related burnout level in the association between sharps injuries and X_i. ^aP < 0.05, ^bP < 0.01, ^cP < 0.0001. ₁: Frequent lower limb pain; ₂: Frequent upper limb pain; ₃: Experience of overtime vs seldom worked overtime; ₄: Doctors vs Nurses and others; ₅: Irregular work shifts vs other work schedules; a_i: The logistic regression coefficient of risk factors for the association between sharps injurie (SI) and risk factors; s_ai: The standard error of a_i; b_i: The logistic regression coefficient of burnout as an adjusted variable with regard to the association between SI and X_i; s_bi: The standard error of b_i. SI: Sharps injurie; HPBL: High personal burnout level; HWBL: High work-related burnout level.

Figure 2 Mediation effects of frequent lower limb pain/frequent upper limb pain in the association between sharps injuries and X_i. ^aP < 0.05, ^bP < 0.01, ^cP < 0.0001. ₁: High personal burnout level; ₂: High work-related burnout level; ₃: Experience of overtime vs seldom worked overtime; ₄: Doctors vs Nurses and others; ₅: Irregular work shifts vs other work schedules; a_i: The logistic regression coefficient of risk factors for the association between sharps injuries (SI) and risk factors; s_ai: The standard error of a_i; b_i: The logistic regression coefficient of burnout as an adjusted variable with regard to the association between SI and X_i; s_bi: The standard error of b_i. SI: Sharps injurie; FLLP: Frequent lower limb pain; FULP: Frequent upper limb pain.

Figure 3 Simple mediation model for burnout and frequent lower limb pain. X_i and Y are the independent and dependent variables, respectively, whereas M_i is the mediating factor of sharps injuries (Y) and X_i. FLLP: Frequent lower limb pain; HPBL: High personal burnout level; HWBL: High work-related burnout level; EOT: The experience of overtime (work); IRWS: Irregular work shifts.
