Mortality of elderly patients in Ontario after hospital admission for chronic obstructive pulmonary disease
Abstract
Background: Chronic obstructive pulmonary disease (COPD) is associated with significant mortality. It is currently the fourth leading cause of death in Canada and the world.
Objectives: To describe the mortality of elderly patients in Ontario after hospital admission for COPD.
Methods: A retrospective cohort study was conducted using the Discharge Abstract Database from the Canadian Institute for Health Information. Patients aged 65 years and older who were admitted to hospital between 2001 and 2004 with primary discharge diagnoses labelled with International Classification of Diseases, Ninth Revision codes 491, 492 and 496 were included in the study.
Results: Mortality rates were 8.81, 12.10, 14.53 and 27.72 per 100 COPD hospital admissions at 30, 60, 90 and 365 days after hospital discharge, respectively. Mortality also increased with age, and men had higher rates than women. No significant differences in mortality rates were found between different socioeconomic groups (P>0.05). Patients with shared care of a family physician or general practitioner and a specialist had significantly lower mortality rates than the overall rate (P<0.05), and their rates were approximately one-half the rate of patients with only one physician.
Conclusions: Hospitalization with COPD is associated with significant mortality. Patients who were cared for by both a family physician or general practitioner and a specialist had significantly lower mortality rates than those cared for by only one physician, suggesting that continuous and coordinated care results in better survival.
CONTEXTE :: La bronchopneumopathie chronique obstructive (BPCO) est associée à une forte mortalité; en fait, elle est la quatrième cause de mortalité au Canada et dans le monde, aujourd’hui. BUT : L’étude avait pour but de caractériser la mortalité chez des patients âgés en Ontario, hospitalisés pour une BPCO.
MÉTHODE :: Nous avons entrepris une étude de cohortes, rétrospective à partir de la Base de données sur les congés des patients, obtenue de l’Institut canadien d’information sur la santé. Ont été inclus dans l’étude des patients âgés de 65 ans et plus, hospitalisés entre 2001 et 2004 pour des affections dont le diagnostic principal, indiqué sur le formulaire de congé, portaient les codes 491, 492 ou 496, selon la Classification internationale des maladies, 9e révision.
RÉSULTATS :: Les taux de mortalité pour 100 hospitalisations motivées par une BPCO étaient respectivement de 8,81; 12,10; 14,53 et 27,72 au bout de 30, 60, 90 et 365 jours après le congé de l’hôpital. La mortalité augmentait également avec l’âge et elle était supérieure chez les hommes par rapport aux femmes. Nous n’avons pas noté d’écart significatif de taux de mortalité entre les différents groupes socio-économiques (P>0,05). Cependant, les patients suivis à la fois par un médecin de famille ou un omnipraticien et un spécialiste ont connu des taux de mortalité significativement plus faibles que l’ensemble des patients (P<0,05), et leurs taux étaient à peu près la moitié de ceux enregistrés chez les patients suivis par un seul médecin.
CONCLUSIONS :: L’hospitalisation pour cause de BPCO est associée à une mortalité élevée. Les patients suivis à la fois par un médecin de famille ou un omnipraticien et un spécialiste ont connu des taux de mortalité significativement plus faibles que les patients suivis par un seul médecin, ce qui porte à croire que des soins continus et coordonnés favorisent une survie prolongée.
