Affect of the 2011 duty hour regulations on number of patient admissions Discussion I. Average number of new admissions Total number of patients admitted to housestaff at UWMC and HMC per day is unchanged Post 2011 duty hour regulations, day medicine interns admit fewer patients -decreased admitting time -Two 8-10 hour blocks post-2011 vs. one 24 hour block pre shared admitting time -2 teams admitting simultaneously -teams rarely reach maximum (cap) -UWMC: max 5, actual 3.1 -HMC: max 10, actual 7.9 -schedules are not equivalent -HMC: pre: 7-9 max per cycle post: 5 max per cycle -UWMC: pre: 7 max per cycle post: 5 max per cycle Number of inpatient general medicine admissions per year per intern is similar with inclusion of night medicine *calculated values based on results and team structure, excludes VA rotation II. Average Team Census On a daily basis, current PGY-1 residents care for a similar number of patients as interns prior to 2011 III. Distribution of Admissions Currently day medicine residents admit a higher proportion of patients as ICU transfers and from clinic, fewer from ED -ICU/clinic patients have been seen by an IM attending prior to admission -night medicine admits almost exclusively from the ED Conclusion It is reassuring that the number of new admissions has remained constant. The current system, although involving more transitions in care, may prepare trainees to the extent that this model reflects handoff patterns in community practice Ideally the decrease in daytime admissions will allow residents to more thoughtfully approach their patient encounters and attend conferences Night Medicine is taking on a much more important role In resident training II. Average Daily Census HMC UMWC Methods Population: Patients cared for by University of Washington PGY-1 residents on general inpatient and night medicine rotations Setting: University of Washington Medical Center (UWMC) and Harborview Medical Center (HMC). Data source: Database records from a shared electronic medical record (Cerner PowerChart) with signout software (CORES) -Review Method: Chart review for abstraction of administrative data -Chart selection: All admission notes from a random sample of 56 days in academic year and Data abstracted: the admitting physician and source (ED, ICU transfer, hospital transfer, team transfer, clinic admit), cross referenced against resident schedules to identify the admitting team -Endpoints: Number of new admissions handled by the primary/night team each day, average team census at midnight Institutional Review Board Approval was obtained from the University of Washington Human Subjects Division Statistical Analysis performed with assistance of the UW Biostatistics Graduate Student Consulting Program Blue represents academic year and Red represents academic year Each dot represents the number of new admissions to the hospital (y-axis) on the day of interest (x-axis). The scatter plots above shows the total number of new medicine admissions per day to the hospital (regardless of admitting team). The scatter plots below shows the number of new admissions per day done by the primary inpatient resident medicine service. Day Of Interest The above pie charts demonstrate how the source of admissions to the primary medicine team has changed as a results of the new duty hour regulations. Overall a similar number of patients are being admitted from each respective source, however, day medicine residents are now admitting fewer ED patients and more patients as ICU transfers and from clinic Average daily census per intern at each institution has remained constant following implementation of the 2011 duty hour regulations Average number of new admissions per day to each hospital and the number/percentage admitted by the primary medicine service prior to and following the 2011 duty hour regulations Day Of Interest Harborview Medical Center UW Medical Center Number of Admissions HMCUWMCFloatTotal
