Abstract
Background: Upper respiratory tract illnesses have been associatedwith an increased risk of morbidity and mortality.Objective: To assess the influence of vaccinationagainst influenza on the risk of hospitalization in internal medicine and geriatric wards, andthe risk of death from all causes during the 2000–2001 influenza season.Methods: A historical cohort study was conducted using computerized general practitioner records on patients aged 65 years and above, members of “Maccabi Health Care Services” – the second largest health maintenance organization in Israel with 1.6 million members. The patients weredivided into high and low risk groups corresponding to coexisting conditions, and were studied. Administrative and clinical data were used to evaluateoutcomes.
Results: Of the 84,613 subjects in the cohort 42.8% were immunized. At baseline,vaccinated subjects were sicker and had higher rates of coexisting conditions than unvaccinated subjects. Vaccination against influenza was associatedwith a 30% reduction in hospitalization rates and 70% in mortality rates in the high risk group. The NNT (number needed to treat) measured to prevent one hospitalization was 53.2 (28.2 in the high risk group and 100.4 in the low risk group). When referring to length of hospitalization, one vaccine was needed to prevent 1 day of hospitalization among the high risk group. Analyses according to age and the presence or absence of majormedical conditions at baseline revealed similar findingsacross all subgroups.Conclusions: In the elderly, vaccination against influenza isassociated with a reduction in both the total risk of hospitalization and in the risk of death from all causes during the influenzaseason. These findings compel the rationale to increase compliance with recommendations for annual influenza vaccination among the elderly.
