The association of hospitalist medical procedure service with operational efficiency at an academic medical center.

We examined the impact of a hospital medicine medical procedure service (MPS) on hospital length of stay (LOS), postprocedure LOS, and completion of procedures on weekends. We included 4952 patients admitted to our large academic hospital between July 1, 2021 and July 31, 2023 who underwent thoracentesis, paracentesis, or lumbar puncture (LP). MPS performed 30% (1499) of these procedures. After adjusting for age, sex, body mass index, Charlson comorbidity score, and procedure type, procedure performance by MPS was associated with a shorter total hospital LOS (incidence rate ratio [IRR]: 0.93; 95% confidence interval [CI]: 0.87-0.99) and postprocedure LOS (IRR: 0.82; 95% CI: 0.76-0.88). Also, MPS-performed procedures were twice as likely to occur on weekends compared to non-MPS-performed procedures (odds ratio [OR]: 2.05; 95% CI: 1.75-2.41). These findings support the beneficial impact of MPS on operational efficiency, an important outcome for both patients and hospitals.
