Ten-year trends in Canada for selected operations

W R Mindell, E Vayda, B Cardillo

    Canadian Medical Association Journal
    |July 1, 1982
    PubMed
    Summary

    Canadian surgical procedure rates for discretionary operations showed significant variation over a decade, unlike non-discretionary procedures. Resource availability did not explain these trends, suggesting other factors influenced surgical practice variations across provinces.

    Area of Science:

    • Health Services Research
    • Surgical Outcomes
    • Canadian Healthcare Policy

    Background:

    • Understanding trends in surgical procedure rates is crucial for healthcare planning and resource allocation.
    • Discretionary surgical procedures, unlike non-discretionary ones, may be more susceptible to variations in practice patterns.
    • Previous research has not fully elucidated the factors driving interprovincial variations in surgical rates in Canada.

    Purpose of the Study:

    • To analyze national and provincial trends in the rates of 16 common surgical operations in Canada over a 10-year period.
    • To compare the variability in rates between discretionary and non-discretionary surgical procedures.
    • To investigate the association between surgical rates and the availability of hospital beds and surgeons.

    Main Methods:

    • Retrospective analysis of administrative health data from Canada over a 10-year period.
    • Calculation of national and provincial rates for 16 common surgical procedures.
    • Statistical analysis to assess trends, variability, and associations with resource availability.

    Main Results:

    • Significant variation in rates was observed for 9 discretionary procedures compared to non-discretionary ones.
    • Rates for tonsillectomy/adenoidectomy, hemorrhoidectomy, varicose vein stripping, and appendectomy decreased.
    • Rates for lens extraction, cesarean section, and colectomy increased, while hysterectomy and cholecystectomy showed a rise then fall. Provincial trends largely mirrored national patterns.
    • No significant association was found between surgical rates and hospital bed or surgeon availability.

    Conclusions:

    • Discretionary surgical procedures exhibit greater rate variability than non-discretionary procedures in Canada.
    • Provincial variations in surgical rates are likely influenced by factors beyond resource availability, such as clinical practice guidelines and patient demand.
    • Further research is needed to identify the specific non-resource-related factors driving these observed trends in Canadian surgical utilization.
