Introduction
Chronic kidney disease (CKD) is widely prevalent, associated with morbidity and mortality, but may be lessened with timely implementation of evidence-based strategies including blood pressure (BP) control. Nonetheless, an evidence-practice gap persists. We synthesize the evidence for clinician-facing interventions to improve hypertension management in CKD patients in primary care.
Methods
Electronic databases and related publications were queried for relevant studies. We used a conceptual model to address heterogeneity of interventions. We conducted a quantitative synthesis of interventions on blood pressure (BP) outcomes and a narrative synthesis of other CKD relevant clinical outcomes. Planned subgroup analyses were performed by (1) study design (randomized controlled trials (RCTs) or nonrandomized studies (NRS)); (2) intervention type (guideline-concordant decision support, shared care, pharmacist-facing); and (3) use of behavioral/implementation theory.
Results
Of 2704 manuscripts screened, 73 underwent full-text review; 22 met inclusion criteria. BP target achievement was reported in 15 and systolic BP reduction in 6 studies. Among RCTs, all interventions had a significant effect on BP control, (pooled OR 1.21; 95% CI 1.07 to 1.38). Subgroup analysis by intervention type showed significant effects for guideline-concordant decision support (pooled OR 1.19; 95% CI 1.12 to 1.27) but not shared care (pooled OR 1.71; 95% CI 0.96 to 3.03) or pharmacist-facing interventions (pooled OR 1.04; 95% CI 0.82 to 1.34). Subgroup analysis finding was replicated with pooling of RCTs and NRS. The five contributing studies showed large and significant reduction in systolic BP (pooled WMD − 3.86; 95% CI − 7.2 to − 0.55). Use of a behavioral/implementation theory had no impact, while RCTs showed smaller effect sizes than NRS.
Discussion
Process-oriented implementation strategies used with guideline-concordant decision support was a promising implementation approach. Better reporting guidelines on implementation would enable more useful synthesis of the efficacy of CKD clinical interventions integrated into primary care.
