Physician impact analysis predictions in Ontario hospitals: does the emperor have clothes?

Physician impact analysis (PIA) is a human resource planning tool used to predict the impact on hospital resources of adding a new or replacement physician to a hospital's medical staff. This article describes the findings of a study which examined the extent to which PIAs are used in Ontario acute care hospitals and the accuracy of PIA predictions. The results suggest that although PIA appears to be widely used, there is no evidence that it meets the intended policy objective of accurately predicting physician hospital resource use.

Evaluating physician impact analysis. Methods, results, and uses in Ontario Hospitals

Physician impact analysis (PIA) is a planning tool intended to bring greater predictability to hospital medical staff resource planning by providing a means to predict the impact of a new or replacement physician's practice profile on a hospital's clinical program priorities, staffing resources, and costs. Two key methods advocated to undertake PIAs are the Department Survey Method and the Hospital Medical Records Institute Case-Mix Groups/Resource Intensity Weights Methods developed by the Hospital Medical Records Institute. This article discusses issues related to the methods, results, and uses of PIA information in Ontario hospitals. Further evaluation of the PIA process is recommended to increase our understanding of both the strengths and limitations of this planning tool.

Revisiting physician impact analyses: predicted versus observed hospital resource use

In order to determine the accuracy of predictions made using Physician Impact Analysis (PIA), a comparison was undertaken of predicted versus actual resource use for 10 new physician specialists at a southern Ontario community hospital. The predictions were done from 1987 to 1989 using methodology recommended by the Ontario Hospital Association (OHA) and available at that time. This included (1) Hospital Medical Records Institute data and (2) a hospital service department survey. A comparison was made between PIA predictions and actual physician resource utilization data gathered in 1991. There was little agreement between the two. The usefulness of PIA rests largely on its ability to generate accurate predictions about a new physician recruit's number of cases and hospital resource use. However, because this research was undertaken in only one community hospital, further evaluation of the PIA process is recommended.
