[Practice guideline 'Influenza prevention in nursing homes and care homes', issued by the Dutch Society of Nursing Home Specialists; division of tasks between nursing home specialist, general practitioner and company doctor].

The Dutch Society of Nursing Home Specialists has formulated a guideline for the prevention of influenza in nursing homes and care homes in The Netherlands. The guideline recommends the realisation of the highest possible degree of vaccination of both patients and health care workers. At the start of the flu season, the manager of the chronic care institute should organize a scheme for vaccination against influenza and a plan in case of an outbreak of influenza. The division of tasks between the nursing home specialist, the general practitioner and the company doctor should be recorded in both the vaccination scheme and the outbreak plan. In order to decrease the incidence of non-response to the vaccine a double dose of influenza vaccine for nursing home patients should be considered. The outbreak plan should raise the state of alertness for influenza and ensure that virological confirmation of clinical influenza is obtained quickly. Immediately after virological confirmation of clinical influenza, patients with influenza should be treated with oseltamivir and both patients and health care workers in the unit should receive prophylaxis with oseltamivir. Non-vaccinated patients should also be offered vaccination to restrict re-introduction of the virus. During an influenza outbreak, only patients with influenza or those who have had prophylactic treatment may be admitted to the facility. In the case of an influenza pandemic, national guidelines should be followed.
