North Hammersmith stroke prevention project
Insights
The North Hammersmith project improved hypertension detection and treatment adherence, significantly reducing stroke risk. This initiative involved general practitioners identifying and monitoring patients with high blood pressure.
Area of Science:
- Public Health
- Cardiovascular Medicine
- Preventive Cardiology
Background:
- Stroke remains a leading cause of mortality and disability.
- Effective management of hypertension is crucial for stroke prevention.
- Early detection and consistent treatment adherence are key challenges in hypertension control.
Purpose of the Study:
- To reduce stroke-related deaths in North Hammersmith.
- To enhance the identification of hypertensive individuals.
- To decrease treatment default rates among hypertensive patients.
Main Methods:
- General practitioners (GPs) registered patients over 40 with hypertension from May 1979.
- Practices' registration proportions were compared annually.
- Patient treatment adherence was monitored over three years.
Main Results:
- 40 of 44 eligible GPs participated; 29 registered patients.
- 1006 hypertensive patients (4.3% of eligible population) were registered.
- Average baseline blood pressure was 190/111 mm Hg.
- Persistent treatment default was below 12% over three years.
Conclusions:
- The project successfully increased hypertension detection and management.
- Sustained treatment adherence was achieved in the majority of registered patients.
- This model shows promise for broader stroke prevention strategies.
Abstract:
The North Hammersmith stroke prevention project was designed to reduce the number of deaths from stroke in this health district by improving the detection of hypertensive patients and thereafter reducing the default rate from treatment. Starting in May 1979 general practitioners in the district were asked to register hypertensive patients over the age of 40 so that the proportion of such patients in each practice was known and could be compared with the average for all practices. This confidential information was fed back every year to the individual general practitioners so that they could assess their performance. Forty of 44 eligible general practitioners agreed to participate and 29 proceeded to register patients. Over a three year period 1006 patients were registered, representing 4.3% of the project population over the age of 40. Individual practice registration rates ranged from 1.1% to 9.1%. Sixty five per cent of the registered patients were women, 34% of all registrations were in the age group 60-69, 31% in the group 50-59, 12% in the group 40-49, and 23% in the group over 70. The average blood pressure before treatment was 190/111 mm Hg. After one and two years the patients were contacted or their notes examined to ensure that they still receiving treatment. Persistant default from treatment occurred in under 12% over the three year period.
