Effect of Attending Practice Style on Generic Medication Prescribing by Residents in the Clinic Setting: An Observational Study. Academic Article uri icon

Overview

abstract

  • BACKGROUND: Despite increased emphasis on cost-consciousness in graduate medical training, there is little empirical evidence of the role of attending physician supervision on resident practice in this area. OBJECTIVE: To study whether the prescribing practices of attendings influence residents' prescribing of brand-name statin medications in the ambulatory clinic setting. DESIGN AND PARTICIPANTS: A retrospective study of statin prescriptions by residents at two internal medicine residency programs, using electronic medical record data from July 2007 through November 2011. MAIN MEASURES: We estimated multivariable hierarchical logistic regression models to assess the independent effect of the supervising attending's rate of brand-name prescribing in the preceding quarter on the likelihood of a resident prescribing a brand-name statin. KEY RESULTS: The sample included 342 residents and 58 attendings, accounting for 10,151 initial statin prescriptions, including 3,942 by residents. Brand-name statins were prescribed in about one-fourth of encounters. After adjusting for patient-, physician-, and practice-level factors, the supervising attendings' brand-name prescribing rate in the quarter preceding the encounter was positively associated with a postgraduate year (PGY)-1 resident's prescribing a brand-name statin, but not for PGY-2 or PGY-3 residents. For PGY-1 residents, the adjusted probability of a resident prescribing a brand-name statin ranged from 22.6 % (95 % CI 17.3-28.0 %, p < 0.001) for residents supervised by an attending who prescribed < 20 % brand-name statins in the previous quarter to 41.6 % (95 % CI 24.6-58.5 %, p < 0.001) for residents supervised by an attending who prescribed at least 80 % brand-name statins in the previous quarter. A higher PGY level was associated with brand-name prescribing (aOR 2.07, 95 % CI 1.28-3.35, p = 0.003 for PGY-2; aOR 2.15, 95 % CI 1.31-3.55, p = 0.003 for PGY-3, vs. PGY-1). CONCLUSIONS: Supervising attendings' prescribing of brand-name medications may have a significant influence on PGY-1 residents' prescribing of brand-name medications, but not on prescribing by more senior residents.
