Changing preventive practice: a controlled trial on the effects of outreach visits to organise prevention of cardiovascular disease.

OBJECTIVES: To assess the effects of outreach visits by trained nurse facilitators on the organisation of services used to prevent cardiovascular disease. To identify the characteristics of general practices that determined success. DESIGN: A non-randomised controlled trial of two methods of implementing guidelines to organise prevention of cardiovascular disease: an innovative outreach visit method compared with a feedback method. The results in both groups were compared with data from a control group. SETTING AND SUBJECTS: 95 general practices in two regions in The Netherlands. INTERVENTIONS: Trained nurse facilitators visited practices, focusing on solving problems in the organisation of prevention. They applied a four step model in each practice. The number of visits depended on the needs of the practice team. The feedback method consisted of the provision of a feedback report with advice specific to each practice and standardised instructions. MAIN OUTCOME MEASURES: The proportion of practices adhering to 10 different guidelines. Guidelines were on the detection of patients at risk, their follow up, the registration of preventive activities, and teamwork within the practice. RESULTS: Outreach visits were more effective than feedback in implementing guidelines to organise prevention. Within the group with outreach visits, the increase in the number of practices adhering to the guidelines was significant for six out of 10 guidelines. Within the feedback group, a comparison of data before and after intervention showed no significant differences. Partnerships and practices with a computer changed more. CONCLUSION: Outreach visits by trained nurse facilitators proved to be effective in implementing guidelines within general practices, probably because their help was practical and designed for the individual practice, guided by the wishes and capabilities of the practice team.

Intensive support to improve clinical decision making in cardiovascular care: a randomised controlled trial in general practice

Objective: To evaluate the effects of feedback reports combined with outreach visits from trained non-physicians on the clinical decision making of general practitioners (GPs) in cardiovascular care. Design: Pragmatic cluster controlled trial with randomisation of practices to support (intervention group) or no special attention (control group); analysis after 2 years. Setting: 124 general practices in The Netherlands. Participants: 185 GPs. Main outcome measures: Compliance rates for 12 evidence-based indicators for the management of patients with hypertension, hypercholesterolaemia, angina pectoris, or heart failure. The evaluation relied on the prospective recording of patient encounters by the participating GPs. Results: The GPs reported 30 101 clinical decisions at baseline and 22 454 decisions after the intervention. A significant improvement was seen for five of the 12 indicators: assessment of risk factors in patients with hypercholesterolaemia (odds ratio 2.04; 95% CI 1.44 to 2.88) or angina pectoris (3.07; 1.08 to 8.79), provision of information and advice to patients with hypercholesterolaemia (1.58, 1.17 to 2.13) or hypertension (1.55, 1.35 to 1.77), and checking for clinical signs of deterioration in patients with heart failure (4.11, 2.17 to 7.77). Single handed practices, non-training practices, and practices with older GPs gained particular benefit from the intervention. Conclusions: Intensive support from trained non-physicians can alter certain aspects of the clinical decision making of GPs in cardiovascular care. The effect is small and the strategy needs further development.

Effects of outreach visits by trained nurses on cardiovascular risk-factor recording in general practice: A controlled trial

Objectives: To study the effects of outreach visits by trained nurses on cardiovascular risk-factor recording. This strategy was compared with a strategy composed of more commonly used methods to improve the quality of care in general practice such as written feedback. Methods: A controlled trial was conducted, in which 33 practices were visited by a trained nurse, 31 practices received written feedback and 31 other practices served as controls. To assess the level of risk-factor recording a chart audit was carried out before and after 18 months of intervention. A sample of medical records of patients aged 30 to 60 was evaluated looking for risk-factor entries: their presence, their combined presence, and their signal function to indicate a risk patient. Risk factors considered were: blood pressure, individual (medical) history as well as family history of cardiovascular diseases, smoking status, serum cholesterol, body weight and alcohol intake. Results: In practices visited by a trained nurse, a significant increase in the recording of most risk factors was found for the presence, the combined presence as well as the signal function. The increase in the presence of entries was consistent in all risk factors and independent of the baseline level. Changes in the group receiving written feedback were inconsistent and statistically not significant. Conclusions: Outreach visits by trained nurses is an effective tool to increase cardiovascular risk-factor recording in general practice.
