Bottom Line: At 12 months, mean systolic BP, diastolic BP and LDL-C was 3.3 (95% CI 0.3 to 6.3) mmHg, 2.3 mmHg (95% CI 0.5 to 4.2) and 0.3 mmol/L (95% CI 0.1 to 0.4) lower in the intervention group compared to controls.Nurse-led, telephone-based secondary preventive follow-up, including medication adjustment, was significantly more efficient than usual care at improving BP and LDL-C levels by 12 months post-discharge.ISRCTN Registry ISRCTN23868518.

ABSTRACT

Background: Enhanced secondary preventive follow-up after stroke or transient ischemic attack (TIA) is necessary for improved adherence to recommendations regarding blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) levels. We investigated whether nurse-led, telephone-based follow-up was more efficient than usual care at improving BP and LDL-C levels at 12 months after hospital discharge.

Methods: We randomized 537 patients to either nurse-led, telephone-based follow-up (intervention) or usual care (control). BP and LDL-C measurements were performed at 1 month (baseline) and 12 months post-discharge. Intervention group patients who did not meet target values at baseline received additional follow-up, including titration of medication and lifestyle counselling, to reach treatment goals (BP < 140/90 mmHg, LDL-C < 2.5 mmol/L).

Results: At 12 months, mean systolic BP, diastolic BP and LDL-C was 3.3 (95% CI 0.3 to 6.3) mmHg, 2.3 mmHg (95% CI 0.5 to 4.2) and 0.3 mmol/L (95% CI 0.1 to 0.4) lower in the intervention group compared to controls. Among participants with values above the treatment goal at baseline, the difference in systolic BP and LDL-C was more pronounced (8.0 mmHg, 95% CI 4.0 to 12.1, and 0.6 mmol/L, 95% CI 0.4 to 0.9). A larger proportion of the intervention group reached the treatment goal for systolic BP (68.5 vs. 56.8%, p = 0.008) and LDL-C (69.7% vs. 50.4%, p < 0.001).

Conclusions: Nurse-led, telephone-based secondary preventive follow-up, including medication adjustment, was significantly more efficient than usual care at improving BP and LDL-C levels by 12 months post-discharge.

Mentions: Group allocation (intervention vs. control) and baseline values for BP/LDL-C (participants found above or below the target value) showed a significant interaction effect with the SBP (p = 0.001) and LDL-C (p < 0.001) levels measured at the 12-month follow-up, respectively (Fig 3). In the subgroup of participants who had a BP measurement above the target value at baseline, the adjusted mean SBP in the intervention group at 12 months was 8.0 (95% CI 4.0 to 12.1) mmHg lower compared to the control group. In the corresponding analysis for LDL-C, the adjusted mean at 12 months was 0.6 (95% CI 0.4 to 0.9) mmol/L lower. Conversely, no significant differences in SBP or LDL-C levels were observed at the 12-month follow-up between participants in the intervention group and control group whose values were below the respective targets at baseline.
