Background: Resident work-hour limitations require new models of care for hospitalized patients. Many academic medical centers have hired physician assistants to work with hospitalists to provide care. Little is known about how these models affect such outcomes as LOS, inpatient mortality rates, and readmission rates.
Study design: Retrospective cohort.
Setting: A 430-bed urban academic medical center in Milwaukee.
Synopsis: Administrative data were gathered on 9,681 patients admitted to the general medical service. Of those enrolled, 2,171 were cared for by a hospitalist-physician assistant (H-PA) team, while resident-hospitalist teams cared for 7,510 patients. Patient assignment was dependent on time of admission but not on patient complexity. Patients admitted overnight after the resident team capped were assigned to the H-PA team the next morning, resulting in increased transitions of care for the H-PA team.
Adjusted analyses revealed a 6.45% increase in LOS for the H-PA team compared with the resident team. Charges, inpatient mortality, and readmission rates at seven, 14, and 30 days were unchanged. Subgroup analyses revealed smaller differences in LOS for H-PA teams and resident-hospitalist teams with the same hospitalist (LOS 5.44% higher, P=0.081).
Conclusions from this study are limited due to lack of randomization of assignment, the retrospective design, and the use of administrative data at one institution.
Bottom line: Hospitalist-PA teams might result in a slightly increased LOS compared with the traditional resident teams; however, inpatient mortality and readmission rates are similar.
