Hepatic resection in Canada: rates and geographic variation

Ryan J McColl et al. Can J Surg. 2009 Dec.

Abstract
in English, French

Background: Liver resection (LR) is the only curative therapy for hepatic malignancy. Despite this, the rates of LR across Canada are unknown. We sought to determine the rate and regional variation of LR in Canada, its provinces and census divisions for the period 1995-2004.

Methods: We obtained discharge data for 1995-2004 from all provinces but Quebec from the Canadian Institute for Health Information, and we searched for LR by residential site. Then we calculated rates and variations in rates.

Results: The national age- and sex-adjusted rate of LR per 100,000 people aged 18 years and older increased from 3.22 in 1995 to 5.86 in 2004. There was a high degree of variation across provinces and census divisions.

Conclusion: Liver resection volumes are increasing in Canada. Significant regional variation exists for LR in Canada, likely reflecting a variety of important supply-demand issues.

Contexte: La résection est la seule thérapie curative contre le cancer du foie. En dépit de cela, on ne connaît pas les taux de résection du foie au Canada. Nous avons cherché à déterminer le taux et la variation régionale des résections du foie au Canada, dans ses provinces et ses divisions de recensement au cours de la période de 1995 à 2004.

Méthodes: Nous avons obtenu de l’Institut canadien d’information sur la santé des données sur les congés d’hôpital de 1995 à 2004 pour toutes les provinces sauf le Québec et nous y avons cherché des résections du foie par établissement. Nous avons ensuite calculé les taux et leur variation.

Résultats: Le taux national corrigé selon l’âge et le sexe de résection du foie pour 100 000 personnes âgées de 18 ans et plus est passé de 3,22 en 1995 à 5,86 en 2004. Il y avait une variation importante entre les provinces et les divisions de recensement.

Conclusion: Les taux de résection du foie sont à la hausse au Canada, et il existe des variations régionales importantes de cette intervention au pays, ce qui reflète probablement tout un éventail d’enjeux importants liés à l’offre et à la demande.
