Abstract

We describe the age-specific outcomes for patients hospitalized with newly diagnosed congestive heart failure using administrative hospital abstracts from Alberta, Canada, from April 1, 1994, to March 31, 2000. Seniors (aged 65 years and older) constituted about 85 per cent of the 16,162 patients. Both co-morbidity and severity of illness tended to increase with age. The use of special care unit admissions, coronary artery diagnostic services (cardiac catheterization), and revascularization procedures (percutanenous transluminal coronary angioplasty/stenting, coronary artery bypass surgery) peaked in the 50-to 64-year age group and decreased with increasing age. Specialist/sub-specialist care, prescriptions of beta blockers and angiotensin-converting enzyme inhibitors / angiotensin receptor blockers decreased with age in seniors. Adjusted in-hospital, 1-year mortality and crude, age-specific 5-year mortality were significantly greater in those 75 years and older. Outcomes and process of care in patients with newly diagnosed congestive heart failure were not uniformly distributed with age. The elderly had greater mortality but received less therapy.

Résumé

Nous décrivons les résultats par âge des patients hospitalisés après un diagnostic récent d'insuffisance cardiaque globale, pour cela nous avons analysé les dossiers administratifs de divers hôpitaux situés en Alberta, au Canada, pour la période allant du 1er avril 1994 au 31 mars 2000. Près de 85 % des 16 162 patients sur lesquels portait l'étude étaient des personnes âgées (de 65 ans et plus). La comorbidité et la gravité de la maladie tendent à augmenter avec l'âge. L'admission en unité de soins spéciaux, les services de diagnostic des artères coronaires (cathétérisation cardiaque) et les procédures de revascularisation (angioplastie coronarienne transluminale percutanée/port de stents, pontage aortocoronarien) sont le plus courants chez les personnes âgées de 50 à 64 ans, mais deviennent moins fréquents chez les patients plus âgés. La prestation de soins de spécialistes/sous-spécialistes, la prescription de béta-bloquants et d'enzymes de conversion/d'inhibiteurs de l'angiotensine diminuent à mesure que les aînés avancent en âge. Les données comparatives, à l'hôpital, entre le taux de mortalité après un an et le taux brut de mortalité (par âge) après cinq ans sont considérablement plus élevés chez les personnes âgées de 75 ans et plus. Les résultats et la prise en charge des patients ayant récemment fait l'objet d'un diagnostic d'insuffisance cardiaque globale ne sont pas répartis uniformément selon l'âge : les personnes âgées ayant un taux de mortalité plus élevé, mais recevant moins de soins.
