[Vaccination against influenza in the hospital milieu and by family physicians in Fribourg in 1997: facts and opinions].
The influenza vaccine was underused in Switzerland in 1996, as less than half of people at risk for the disease were vaccinated. We performed this study in 1997 to determine (1) the immunisation rate in the patients admitted to the internal medicine ward of the Cantonal Hospital, Fribourg and in those seen by family physicians, (2) the reasons underlying the decision of the physician to vaccinate their patients or not, (3) the physicians' opinion of the vaccination. The study was retrospective and included 383 patients hospitalised in the medicine ward between October 15 and November 25, 1997. 249 of them (65%) had an indication for vaccination against influenza according to the recommendations of the Federal Office of Public Health. Only 20 patients (8%) were vaccinated during their hospital stay. 86 family physicians (83%) answered the questionnaire concerning 141 patients (57%) whom they examined after their hospital discharge. Of these patients, 77 (55%) were vaccinated by the family physician. The main reason for not vaccinating the patients was the patient's refusal (33%). The effectiveness of the vaccine was considered to be very good (effectiveness > 80%) by 40% of the family physicians and good (effectiveness 60-80%) by 50%. The local and systemic side effects were reported to be rare (incidence < 5%) by 55% and 71% of family physicians respectively. The cost and the route of administration were not felt to have any effect on acceptance of the vaccine. In decreasing importance the family physicians considered the recommendations of the Federal Office of Public Health useful for (1) chronic pulmonary disease, (2) immunosuppression, (3) chronic cardiac disease, (4) chronic renal insufficiency and residency in homes or institutions, (5) diabetes, (6) age over 64, (7) health care workers. In conclusion, the influenza immunisation rate in Fribourg was very low at the hospital but was higher than the Swiss figures for the family physicians. Patient's refusal was the main reason for non-vaccination. The family physicians have a favourable opinion of the effectiveness and tolerance of the influenza vaccine.
