U.S. Trends in Hospitalization and Generalist Physician Workforce and the Emergence of Hospitalists.

BACKGROUND: General internists and other generalist physicians have traditionally cared for their patients during both ambulatory visits and hospitalizations. It has been suggested that the expansion of hospitalists since the mid-1990s has "crowded out" generalists from inpatient care. However, it is also possible that declining hospital utilization relative to the size of the generalist workforce reduced the incentives for generalists to continue providing hospital care. OBJECTIVE: To examine trends in hospital utilization and the generalist workforce before and after the emergence of hospitalists in the U.S. and to investigate factors contributing to these trends. DESIGN: Using data from 1980-2005 on inpatient visits from the National Hospital Discharge Survey, and physician manpower data from the American Medical Association, we identified national trends before and after the emergence of hospitalists in the annual number of inpatient encounters relative to the number of generalists. RESULTS: Inpatient encounters relative to the number of generalists declined steadily before the emergence of hospitalists. Declines in inpatient encounters relative to the number of generalists were driven primarily by reduced hospital length of stay and increased numbers of generalists. CONCLUSIONS: Hospital utilization relative to generalist workforce declined before the emergence of hospitalists, largely due to declining length of stay and rising generalist workforce. This likely weakened generalist incentives to provide hospital care. Models of care that seek to preserve dual-setting generalist care spanning ambulatory and inpatient settings are most likely to be viable if they focus on patients at high risk of hospitalization.

Narrative Review: Should Teaching of the Respiratory Physical Examination Be Restricted Only to Signs with Proven Reliability and Validity?

OBJECTIVE: To review the reported reliability (reproducibility, inter-examiner agreement) and validity (sensitivity, specificity and likelihood ratios) of respiratory physical examination (PE) signs, and suggest an approach to teaching these signs to medical students. METHODS: Review of the literature. We searched Paper Chase between 1966 and June 2009 to identify and evaluate published studies on the diagnostic accuracy of respiratory PE signs. RESULTS: Most studies have reported low to fair reliability and sensitivity values. However, some studies have found high specificites for selected PE signs. None of the studies that we reviewed adhered to all of the STARD criteria for reporting diagnostic accuracy. CONCLUSIONS: Possible flaws in study designs may have led to underestimates of the observed diagnostic accuracy of respiratory PE signs. The reported poor reliabilities may have been due to differences in the PE skills of the participating examiners, while the sensitivities may have been confounded by variations in the severity of the diseases of the participating patients. IMPLICATION FOR PRACTICE AND MEDICAL EDUCATION: Pending the results of properly controlled studies, the reported poor reliability and sensitivity of most respiratory PE signs do not necessarily detract from their clinical utility. Therefore, we believe that a meticulously performed respiratory PE, which aims to explore a diagnostic hypothesis, as opposed to a PE that aims to detect a disease in an asymptomatic person, remains a cornerstone of clinical practice. We propose teaching the respiratory PE signs according to their importance, beginning with signs of life-threatening conditions and those that have been reported to have a high specificity, and ending with signs that are "nice to know," but are no longer employed because of the availability of more easily performed tests.
