Pneumonia and influenza are among the top causes of hospitalisation and death in the elderly. While vaccinations are recommended against these diseases, a large proportion of elderly in the community remain unvaccinated, with approximately only 10% vaccinated for either disease. In this study, the investigators aim to implement an intervention package within GP clinics to increase influenza and pneumococcal vaccination rates, especially among elderly patients with chronic diseases.
Influenza and pneumococcal disease contribute considerably to hospitalisation and mortality in the elderly. While recommended vaccines can reduce disease burden, vaccine uptake remains very low in Singapore, with approximately only 10% of elderly appropriately vaccinated for either disease. Improving vaccine uptake rates could be effected through private sector primary care clinics, which are highly accessible in Singapore. An intervention bundle we piloted in one clinic comprised physician reminders and patient-targeted posters and brochures. Influenza and pneumococcal vaccine rates both increased by >30% over the baseline, although half of eligible patients remained unvaccinated. There is thus scope to devise a more effective intervention bundle and demonstrate its efficacy through a more robust and generalisable study design.
This study aims to evaluate the efficacy of an intervention bundle deployed in general practice clinics to promote influenza and pneumococcal vaccine uptake among elderly patients. The intervention bundle components include educational materials such as posters and flyers, which also serve as reminder slips for attending physicians. The intervention will be implemented in a two-arm cluster randomised crossover trial in up to 30 primary care clinics. Control arm clinics will receive no interventions. Clinics will be randomised into either of the two arms for a period of 3 months, followed by a washout of 1 month before a crossover is performed. The investigators will subsequently compare vaccination rates during intervention and control periods to provide evidence for effectiveness of the intervention.

Interventionsname: Educational intervention
Beschreibung: a) The educational intervention comprises putting up posters on vaccination in the clinic, as well as provision of a specially designed flyer to the clinic, which will be handed out by the clinic assistants to all patients 65 years and above, at the point of registration. The poster and flyer content will provide simple messaging to encourage patients to receive influenza and pneumococcal vaccinations and inform them of available healthcare subsidies. b) Reminders to physicians: The flyers will also serve as physical prompts to physicians to encourage vaccination for their patients. Doctors and clinic staff will also be updated on the study protocol and the recommended adult vaccination schedule before commencement of the study.

Beschreibung: Clinics assigned to the intervention arm will receive an educational intervention. This comprises posters on vaccination to be put up in the clinic, as well as a flyer which will be handed out by the clinic assistants to all patients 65 years and above, at the point of registration. The poster and flyer content will provide simple messaging to encourage patients to receive influenza and pneumococcal vaccinations and inform them of available healthcare subsidies.
