Clinical question: Are there differences in mortality and health care resource utilization in patients treated by hospitalists, primary care physicians, or other generalists?
Background: Most hospitalized patients now are being cared for by hospitalists rather than their primary care physicians (PCP). Covering generalists, who lack a prior relationship with the patient, also care for hospitalized patients when their PCP is unavailable. Although past studies have found some differences in outcomes in patients when care was provided by hospitalists vs. PCPs, those studies have grouped covering generalists with PCPs, which could affect the data.
Study design: Retrospective study.
Setting: Medicare admissions to acute care hospitals in all 50 states from January 2013 to December 2013.
Synopsis: Researchers analyzed data from 560,651 patients admitted with the 20 most common diagnoses looking for differences in health care utilization, length of stay, mortality, and discharge disposition depending on the type of provider: PCP, hospitalist, or other covering generalist. PCPs and other generalists consulted specialists more often than hospitalists. Length of stay was shorter in the hospitalist group. PCPs discharged patients to home more often than the other groups (68.5%, compared with 64% for hospitalists and 62% for other generalists). Readmission rates at 7 days were the same between hospitalists and PCPs but were higher in the other generalist group. PCPs also had lower 30-day mortality, compared with hospitalists (8.6% vs. 10.8%), while other generalists had higher mortality at 11%. Limitations include the use of administrative data and including only Medicare patients.
Bottom line: Inpatient care by PCP decreases mortality and increases likelihood of discharging home compared to care by hospitalists or other generalists.
