The 50/50 Block Schedule: Impact on Residents' and Preceptors' Perceptions, Patient Outcomes, and Continuity of Care

ABSTRACT

Problem: Traditionally, internal medicine continuity clinic consists of a half day per week, regardless of rotation, which may create conflict with ongoing inpatient responsibilities. A 50/50 block schedule, which alternates inpatient and outpatient rotations and concentrates continuity clinic during outpatient rotations, minimizes conflicting responsibilities. However, its impact on patient care has not been widely studied. Continuity is a concern, and intervisit continuity in particular has not been evaluated. Intervention: We implemented a 50/50 block model with “clinic buddy” system to optimize continuity and assessed outcomes pre- and postintervention. Residents alternated inpatient and elective blocks, with clinic 1 full day per week on elective blocks only. Resident and preceptor perceptions were measured using 5-point Likert surveys to evaluate impact on clinic experience and workload. The authors calculated visit and intervisit continuity using a Usual Provider of Care index and measured blood pressure and hemoglobin A1c as quality markers to evaluate the impact on continuity and quality of care. Context: Participants were 208 medicine residents and 39 core faculty members at 3 University of Pittsburgh Medical Center clinics. The intervention was implemented in June 2014. Outcome: In the 50/50 system, inpatient distractions decreased (3.59 vs. 1.71, p < .001). Residents more strongly agreed that there was adequate time for conferences (3.33 vs. 4.05), they worked well within the system to achieve best patient care (3.13 vs. 3.61), and multidisciplinary teams worked well together (3.51 vs. 4.08) (all p < .001). Intervisit continuity was unchanged (73%, both models, p = .79). Visit continuity decreased (67.2% vs. 63.7%, p < .001). Blood pressure and hemoglobin A1c were unchanged. Lessons Learned: This 50/50 model minimized inpatient distractions in clinic and increased perceived time for learning. Residents reported improved sense of patient ownership, relations within the multidisciplinary team, and integration into the clinic system. Intervisit continuity was preserved, visit continuity was slightly decreased, and patient outcomes were not impacted in this model.
