SPREAD-NET: PRactices Enabling Adapting and Disseminating in the Safety NET
The investigators propose to compare the effectiveness of 3 strategies (low, medium, high intensity) at supporting CHCs' implementation of the ALL Initiative (an intervention shown to reduce patients' cardiovascular disease (CVD) event risk), through a cluster-randomized trial.
The investigators propose to compare the effectiveness of 3 support strategies for optimizing the sustainable implementation of the evidence-based ALL intervention. To do so, the investigators will randomize 30 community health centers (CHCs) to receive 1 of 3 implementation support strategies: Low support (toolkit only), Medium (toolkit, staff training), High (toolkit, training, on-site facilitation). The study aims are as follows:
Aim 1: Compare the effectiveness of the 3 strategies (low, medium, high intensity) at supporting CHCs' implementation of the ALL intervention, through a cluster-randomized trial.
Hypothesis: Clinics randomized to receive more implementation support will be more likely than those randomized to receive less support (high>medium>low) to significantly improve the percent of their patients with (i) guideline-appropriate prescriptions for ACE/ARBs and statins, and (ii) last blood pressure (BP) and low-density lipoprotein (LDL) under control).
Aim 2: Assess how effectively the 3 strategies support intervention sustainability at 12, 24 and 36 months post-implementation, measured as maintenance of change over time (outcomes as in Aim 1).
Hypothesis: Clinics randomized to receive more implementation support will be more likely to maintain changes in the outcomes of interest.
Aim 3: Identify clinic characteristics associated with the support strategies' effectiveness (e.g. decision-making structures, leadership support, team processes / characteristics, readiness and capacity for change).
Research questions: What are the characteristics of clinics that achieve sustained change even with less implementation support, and of those that do not achieve change even with more support?
