AbstractThis study was undertaken with the objective of assessing current sources of information for anaesthesia Physician Resource Planning (PRP). Four major data bases, the annual reports of Health and Welfare Canada (H&W), the education statistics from the Canadian Post-M.D. Education Registry (CAPER), the Royal College of Physicians and Surgeons of Canada (RCPSC) and the Physician Resource Data System of the Canadian Medical Association (PRDS), were examined for the period 1982 to 1991. The ratio of the number of surgical (S) to anaesthesia (A) clinicians decreased over this period despite an increase in the S:A ratios for trainees and certificants. The number of female anaesthetists has progressively increased. A steady decline in the number of rural anaesthetists has occurred. Age distribution of active certified anaesthetists revealed marked inter-regional differences. Little change was noted in the total mean hours worked per week. Each database provided valuable, but limited, data. The PRDS data is useful in assessing trends (age, sex and practice activity). Information provided by H&W tends to underestimate anaesthesia resource information by at least 10%. While information obtained from RCPSC and CAPER is accurate, the current mode of presentation of data limits their usefulness. Integrating data from all the databases appears to provide a meaningful assessment for PRP rather than assessing each database in isolation. Interpretation of the information and its value must take into account the limitations of the data being provided. Assessing present and planning future needs based on the current information structure will prove extremely difficult.
