The Prevalence and Correlates of Influenza Vaccination Among a Home Care Population

Objective: To estimate the prevalence and correlates of influenza vaccination in a Home Care population.

Methods: This was a cross-sectional investigation involving linkage of three population-based databases from a rural Alberta Regional Health Authority, i.e., the Regional immunization and the Regional home oxygen information systems to the Regional home care information system. The sample comprised 649 persons who had been admitted or discharged from the Regional Home Care Program in the period Oct. 1–Dec. 31, 1998. An anonymous data file was released to the investigators. We estimated the proportion ever vaccinated against influenza, the proportion vaccinated in the period Oct. 1–Dec. 31, 1998 (“currently vaccinated”); and explored sociodemographic and program correlates of current vaccination.

Results: 67% had ever been vaccinated against influenza; 60.7% were currently vaccinated. Factors associated with current vaccination (multivariate analysis) include older age, being married, not receiving nursing services, district of residence and program status.

Conclusions: Influenza vaccination rates were suboptimal. The correlates of vaccination suggest systems-level impediments to influenza vaccination.


Objectif: Évaluer la prévalence et les corrélats de la vaccination antigrippale au sein d’une population recevant des soins à domicile.

Méthode: Enquête transversale recoupant trois bases de données représentatives d’un office régional albertain de la santé. L’office a relié ses systèmes d’information régionaux sur l’immunisation, sur l’oxygénothérapie à domicile et sur les soins à domicile. L’échantillon comprenait 649 personnes admises au programme régional de soins à domicile ou sorties de ce programme entre le 1er oct. et le 31 déc. 1998. Nous avons eu accès à un fichier de données anonymes. Nous avons estimé la proportion de personnes ayant déjà été vaccinées contre la grippe et la proportion de personnes vaccinées entre le 1er oct. et le 31 déc. 1998 (« actuellement vaccinées »), puis étudié les corrélats de la vaccination actuelle à l’égard du profil socio-démographique et de la participation au programme.

Résultats: 67 % des personnes de l’échantillon avaient jamais été vaccinées contre la grippe; 60,7% l’étaient actuellement. Les facteurs associés (par analyse multivariable) à la vaccination actuelle sont la vieillesse, le fait d’être marié, le fait de ne pas recevoir de services infirmiers, le district de résidence et la participation au programme.

Conclusions: Les taux de vaccination contre la grippe sont sous-optimaux. Les corrélats suggèrent la présence d’obstacles systémiques au vaccin antigrippal.
