Abstract
OBJECTIVE
To determine the workload implications for general practice of the Coronary Prevention Group and British Heart Foundation action plan for preventing heart disease.
DESIGN
Computer simulation of plan, including calculation of Dundee risk scores, with data from OXCHECK trial.
SUBJECTS
4759 patients aged 35-64 who had health checks during 1989-91.
MAIN OUTCOME MEASURE
Effect of using different risk scores as thresholds on workload and coverage of patients at known risk. Thresholds of 6-20 were used for cholesterol screening (nearset) and 4-16 for special care (preset).
RESULTS
On the basis of workload a nearset of 8 and preset of 12 would be reasonable. This implies cholesterol measurement in 1794 (37.7%) patients and special care in 1074 (22.6%). However, many patients with single risk factors were not allocated to special care at these thresholds: 11 (37.9%) patients with cholesterol concentrations > or = 10 mmol/l, 21 (33.9%) with systolic pressure > or = 180 mm Hg, and 213 (40.7%) heavy smokers (> 20 cigarettes/day) were missed. The distribution of scores was similar in those at established clinical risk, those with family history of heart disease, and others.
CONCLUSION
The guidelines may help to make best use of resources within specific age-sex groups but sound protocols for unifactorial risk assessment and modification remain essential.
