MODELING THE OUTCOMES OF NURSING HOME CARE Rohrer and Hogan, Soc Sci Med 24(3) 1987 290 VA NH pts - 243 remaining Are the number of minutes of nursing care associated with outcomes when case mix is controlled?
Results of Regression Analysis of Outcome RUG (R -square=.71, N=234) LPN/Aides -.005 Psychosocial -.002 Basic .005 MD notes -.159 RN .013 Initial RUG .475 Rehab n.s.
CONCLUSIONS • The amount of nursing care is associated with outcome functional status. • Non-RN time is associated with better outcomes • RN time is associated with worse outcomes (ameliorative) • Rehab service was not associated with outcomes (constrained range?)
ORGANIZATIONAL PREDICTORS OF OUTCOMES OF LONG-STAY NURSING HOME RESIDENTS • Rohrer et al, Soc Sci Med, 1993 • 10 nursing homes, 32 units, 872 cases • Measures • job assignment vs flexible duties • hierarchy (number of levels of supervision) • closeness of supervision (RNs/nonRNS) • pace (discharges/beds) • workload (percent heavy care residents) • initial and outcome functioning
REGRESSION RESULTS (R-Square=.74) • Job assignment 0.068 • Hierarchy 0.153 • Closeness of supervision n.s. • Pct heavy care 0.207 • Pace 1.044 • Hierarchy x pace -1.074 • Initial functioning 0.743
CONCLUSIONS Residents get worse: under strict job assignment tall hierarchies / large organizations where workload is heavy when pace is fast Residents get better: in large organizations when pace is fast Contingency theory applies - optimal structure depends on circumstances
