Table 2 Effect of a nurse‐and‐physician‐directed heart failure clinic on hospitalisation, death and days in hospital.
| Variable | Intervention group (incidence rate) n = 118 | Usual care group n = 122 | Rate ratio (95% CI) | RD (95% CI; NNT) |
|---|---|---|---|---|
| Hospitalisation for CHF and/or death | 23 (20.7 per 100 patient years) | 47 (42.2 per 100 patient years) | 0.49 (0.30 to 0.81) | 0.215 (0.07 to 0.36; 5) |
| Death (all‐cause) | 12 (10.8 per 100 patient years) | 23 (20.6 per 100 patient years) | 0.52 (0.26 to 1.05) | 0.098 (10) |
| Days in hospital | 359 (324 per 100 patient years) | 644 (578 per 100 patient years) | 0.56 (0.49 to 0.64) | 2.54 (0.4) |
CHF, congestive heart failure; NNT, numbers needed to treat; RD, rate difference.
