Table 5.
Mean blood pressure and cholesterol, and percentage of coronary heart disease patients assumed not smoking at follow up, by trial group. Values are means (range) unless stated otherwise
| Audit group (n=7) | GP recall group (n=7) | Nurse recall group (n=7) | P value for difference between groups | |||
|---|---|---|---|---|---|---|
| Blood pressure (mm Hg): | ||||||
| Systolic | 148 (136-153) | 147 (135-153) | 148 (142-153) | 0.82 | ||
| Diastolic | 81 (75-82) | 81 (75-83) | 80 (74-87) | 0.82 | ||
| Cholesterol (mmol/l): | ||||||
| Total | 5.5 (5.2-6.1) | 5.5 (5.0-5.9) | 5.4 (5.2-5.5) | 0.61 | ||
| High density lipoprotein | 1.2 (1.2-1.3) | 1.2 (1.2-1.3) | 1.2 (1.1-1.3) | 0.83 | ||
| % (range) of assumed non-smokers* | 81 (69-86) | 84 (75-88) | 83 (73-100) | 0.58 |
Means are based on number of patients with coronary heart disease with clinical measurements: blood pressure, n=1341; total cholesterol, n=1286; high density lipoprotein cholesterol, n=1264; cotinine, n=1271.
Overall means and mean percentages are weighted by number of patients in each practice with the relevant measurement.
