2002 DEC 4 - (NewsRx.com & NewsRx.net) -- Two studies published recently in the British Journal of General Practice focused on efforts to boost flu and pneumococcal vaccine rates in primary practices.
A.N. Siriwardena and colleagues conducted a small study on the impact of educational outreach visits to primary healthcare providers in England. The effort met with variable success, according to their findings.
The researchers randomized 15 primary healthcare practices in the Trent region of England to receive the outreach visits and 15 to constitute the control group. All practices were first stratified for baseline influenza and pneumococcal vaccine rates.
"All intervention practices were offered and received an educational outreach visit to primary healthcare teams, in addition to audit and feedback directed at improving influenza and pneumococcal vaccination rates in high-risk groups. Control practices received audit and feedback alone.
"All practices measured influenza and pneumococcal vaccination rates in high-risk groups. Primary outcomes were improvements in vaccination rates in patients aged 65 years and over, and patients with coronary heart disease (CHD), diabetes, and a history of splenectomy." wrote Siriwardena and colleagues (Cluster randomised controlled trial of an educational outreach visit to improve influenza and pneumococcal immunisation rates in primary care. Br J Gen Pract, 2002;52(482):735-740).
The researchers found that "improvements in pneumococcal vaccination rates in the intervention practices were significantly greater compared with controls in patients with CHD, 14.8% versus 6.5% (odds ratio [OR] = 1.23, 95% confidence interval [CI] = 1.13 to 1.34) and diabetes, 15.5% versus 6.8% (OR = 1.18, 95% CI = 1.08 to 1.29), but not splenectomy, 6.5% versus 4.7% (OR = 0.96, 95% CI = 0.65 to 1.42).
"Improvements for influenza vaccination were also usually greater intervention practices but did not reach statistical significance," the authors said.
