Background: Comorbidity scores based on the prediction of 1-year mortality risk are used in pharmacoepidemiologic and pharmacoeconomic research to control for unmeasured confounding. However, admission to a long-term care institution may be a more salient and discriminant outcome on which to base comorbidity scores. Objective: To develop a prescription claims-based comorbidity score to predict institutionalization in the community-dwelling elderly population, and to compare its performance against existing mortality comorbidity scores. Methods: A geriatric institutionalization comorbidity index was derived from data of a retrospective cohort of 61,172 community-dwelling older adults identified through the Quebec claims databases (2000-2009). Predictors of institutionalization were identified through clinical expertise and by nested case-control analysis. The Framingham Heart Study method was used to develop the score. The performance of the score was assessed through the c-statistic in a separate validation cohort of 26,216 persons and compared with the performance of a mortality score, the Geriatric Comorbidity Index. The robustness was assessed in a cohort of elderly individuals with dementia. Results: Drugs associated with an increased risk of institutionalization were: antipsychotics, antidepressants, hypoglycaemic agents, statins, benzodiazepines and antihypertensives. The mean score assigned to cases was significantly different from that of controls. The c-statistic for the Institutionalization Comorbidity Index was 0.79 (95% CI: 0.77-0.83) compared to 0.75 (95% CI: 0.73-0.78) for the mortality index. The score was robust when in the dementia cohort Comorbidity Index was 0.81 95% CI: 0.78-0.84). Conclusion: A score that predicts institutionalization in the community-dwelling elderly population offers improvement over existing comorbidity scores. It may therefore be used in research conducted in this population, especially for drug effectiveness and health economic studies which often involve institutionalization as the outcome of interest.

Le financement des régimes publics de retraite est au coeur des préoccupations reliées au vieillissement démographique. Confrontés à cette problématique, plusieurs pays ont d’ailleurs relevé l’âge ouvrant droit à une pleine rente de retraite. Toutefois, on note un report relativement important de l’âge effectif de la retraite au Canada depuis le milieu des années 1990, sans modifications importantes apportées au système public de retraite. Cette tendance aura comme effet, entre autres, de pallier une épargne-retraite insuffisante chez plusieurs travailleurs ; problématique qu’avait déjà soulevée Jacques Henripin. Cette étude présente d’abord certaines tendances qui pourraient faire en sorte que ce report se poursuive chez les cohortes du baby-boom. La deuxième partie montre qu’une projection de la durée de vie en emploi à 50 ans, avec l’hypothèse de taux de retraite volontaire constants à leur niveau observé en 2011, conduit à une augmentation plus rapide de la durée anticipée de vie en emploi à 50 ans que celle prévue pour l’espérance de vie au même âge. L’effet de la retraite involontaire pourrait toutefois nuancer cette tendance, surtout chez les femmes. La discussion soulève, dans un tel contexte, certains enjeux importants reliés à la nécessité ou non de relever l’âge ouvrant droit à une pleine rente de retraite, qui est fixé à 65 depuis la fin des années 1960.
