Generalist vs specialist acute medical admissions - What is the impact of moving towards acute medical subspecialty admissions on efficacy of care provision?

Introduction: : The discussion surrounding generalist versus specialist acute medical admissions continues to stimulate debate and patients with certain conditions benefit from specialist care. Aim: : To determine whether a specialty medical admission program would reduce inpatient length of stay (LOS), mortality and readmission rates. Design/Methods: : A prospective cohort study of inpatients admitted under a general internal medicine (GIM) service before and after introduction of a specialty-directing programme. We hypothesized that early transfer of patient care to a specialty suited to their presenting complaint would reduce LOS and a specialty-directing early redistribution of care programme was introduced. Seven of the ten clinical teams participating in the GIM roster adopted the programme. On the morning following a specialty-directing team being on call for all new GIM admissions during a 24-hour period, specialty-directing teams were allocated one patient appropriate to their specialty. Results: : 5,144 patient-care episodes were analysed over the two-year study period. LOS increased by greater than 15%, one year after introducing the specialty-directing programme (8.5 +/- 8.4 vs 7.3 +/- 7.5 days, p < 0.001). LOS did not differ between teams that participated and those who did not (8.4 +/- 8.1 vs 8.1 +/- 7.9 days, p = 0.298). No differences were found in the proportion of patients who were discharged home, died while an inpatient or re-admitted within 30 days of discharge. The proportion of patients aged greater than 80 years increased significantly also - from 24.7% in 2017 to 27.9% in 2019(p = 0.009). Conclusion: : Widespread adoption of specialist care may not be beneficial for all medical inpatients and physicians should continue to undergo dual specialist and GIM training.
