Increasing the coverage of vaccination against influenza by general practitioners.

BACKGROUND: To increase the coverage of influenza vaccination in groups of patients at risk, an experiment was conducted in 1993, aimed at logistic support of general practitioners (GPs). METHODS: Support was given to 56 GPs with 133,000 patients to select and invite patients at risk. The coverage of vaccination as a result of this experiment has been compared with the results obtained from the Health Interview Survey, in The Netherlands as a total. RESULTS About 15,000 patients at risk were invited for vaccination, of whom 75.5 per cent were vaccinated. In The Netherlands as a total, the coverage of patients at risk was 43 per cent. CONCLUSION: Because the selection and invitation of patients at risk is still a problem for many GPs, owing to the lack of computerization, logistic support can ease these tasks and thus help increase the coverage of vaccination against influenza in groups of patients at risk.

[Increase of degree of vaccination against influenza in at-risk patients by directed primary care invitation].

OBJECTIVE: To increase the coverage of influenza vaccination by a programmatic approach in a large population, aimed at the general practitioners (GPs). DESIGN: Intervention study (prospective). SETTING: The region of central Brabant (Tilburg and some surrounding communities), the Netherlands. METHOD: The intervention was carried out in a population of 133,000 people (registered at 42 offices of 56 GPs, and at 27 pharmacies). Medication data from pharmacists were used for the selection of patients at risk by the GPs. RESULTS: About 15,000 patients were selected by the GPs and invited for vaccination. The (final) coverage was 75.5% in 1993, a 56% increase over 1992. The increase in the group of comparable but non-participating GPs was 18%, in the Netherlands as a whole it was 8%. CONCLUSION: It is quite possible to achieve a considerable increase of the coverage of influenza vaccination.

[Trends in incidence of sexually transmissible disorders in The Netherlands].

In 1983 the Chief Medical Inspectorate set up a national registration of sexually transmitted diseases (STD), beside the system of statutorily notifiable diseases in the Netherlands. Data for this registration are collected by the nursing staff in STD clinics. Besides diagnosis and sex of the patient epidemiological background information is registered. The data show a decrease in the total number for gonorrhoea and syphilis in the period 1984-1990. Among homosexual men gonorrhoea increased after 1989. A decrease in STD was demonstrated among prostitute women. Further, the share of penicillinase producing Neisseria gonorrhoeae was found to be increasing in various subgroups, but not in homosexual men. Comparison of age, sex, prostitution, and sexual inclination of over 25,000 patients with Chlamydia trachomatis, gonorrhoea or syphilis infections indicate that syphilis was significantly more frequent among older patients and women than gonorrhoea, but less frequent among prostitutes. Syphilis patients were significantly more often visitors of prostitutes than patients with gonorrhoea, and were more often homosexual or bisexual. Chlamydiosis patients were mostly women and younger than gonorrhoea patients, they were less often working as a prostitute and less often homosexual or bisexual.

Sexually transmitted diseases reported by STD services in The Netherlands, 1984-1990.

OBJECTIVE: To present general trends in sexually transmitted disease (STD) in the Netherlands during the period 1984-1990 and to describe characteristics of the patients in order to get insight into possible factors underlying these trends. METHODS: Since 1984 patients diagnosed with STD visiting STD clinics and local public health services in the Netherlands are reported by the nursing staffs. In addition to diagnosis and gender of the patient epidemiological background information is registered. The reported annual cases of gonorrhoea, syphilis and Chlamydia trachomatis infections are presented. Further, the epidemiological features of over 25,000 patients with infections due to Chlamydia trachomatis, gonorrhoea or syphilis infections were compared. RESULTS: During the period 1984-1990 an overall decrease in the total number of gonorrhoea infections was reported; among homosexual males; however, an increase in gonorrhoea rates and an increasing number of sexual partners after 1989 was reported. Furthermore, the percentage of gonorrhoea infections caused by penicillinase-producing Neisseria gonorrhoeae was found to be on the increase in various subgroups but not in homosexual males. Syphilis rates among females declined from 1984 to 1987 after which an increase was reported reaching a peak in 1989; syphilis rates among males peaked during 1989. After 1988 Chlamydia trachomatis infections increased which, however, is largely due to the introduction of screening among all visitors of the Amsterdam STD service resulting in improved case-detection. Finally, it appeared that STDs are not randomly distributed over the population but are associated with certain patient characteristics. CONCLUSION: The data provided by STD services reveal an epidemiological pattern for STDs in the Netherlands. The increase in the reported number of gonorrhoea infections among homosexuals together with the increasing number of sexual partners among homosexual males suggest that a group of highly sexually active individuals switch or return to higher risk behaviours. Further research is needed to determine the causes of the described trends and behavioural changes in order to undertake preventive activities.

[Aphasia in the Netherlands; extent of the problem].

This article reports on a study of the frequency of aphasia in the Netherlands. Using information obtained from a survey of the literature and data from Dutch Sources, we estimated that in 1979 the incidence must have been about 3500 cases and the prevalence about 5100 cases (the first 2 months of the disease and, with regard to the prevalence the period after 2 years, were left out of consideration). Because of some uncertainties these figures must be considered to be crude estimates of the extent of the aphasia problem in the Netherlands.
