The effects of community-infused problem-oriented policing in crime hot spots based on police data: a randomized controlled trial.

Objectives: This randomized controlled trial (RCT) assessed the effectiveness of a community-infused problem-oriented policing (CPOP) intervention on reducing property/violent crime. Methods: In two mid-Atlantic cities, a total of 102 crime hot spots were randomly assigned to receive CPOP or standard patrol. Analyses examine changes in crime the year before, during, and one year after the intervention. We used hierarchical Poisson regression models. Results: We found no main effects for the CPOP intervention on property and violent crimes in either site. In site B, the violent crime count in low treatment hot spots was 200% higher than controls post-intervention but this likely reflected officers paying less attention to treatment locations with lower levels of crime. Conclusions: Our results suggest that CPOP was not effective in the unusual context of the COVID-19 pandemic and post-George Floyd killing. Given the challenges of implementing CPOP during this unique time, caution is needed in interpreting these findings.

Factors Affecting Implementation of Evidence-Based Practices in Public Health Preparedness and Response.

CONTEXT: There is limited research on what factors are most salient to implementation of evidence-based practices (EBPs) among public health agencies in public health emergency preparedness and response (PHPR) and under what conditions EBP implementation will occur. OBJECTIVE: This study assessed the conditions, barriers, and enablers affecting EBP implementation among the PHPR practice community and identified opportunities to support EBP implementation. DESIGN: A Web-based survey gathered information from public health agencies. Data obtained from 228 participating agencies were analyzed. SETTING: State, local, and territorial public health agencies across the United States. PARTICIPANTS: Preparedness program officials from 228 public health agencies in the United States, including Public Health Emergency Preparedness (PHEP) cooperative agreement awardees (PHEP awardees) and a random sample of local health departments (LHDs). RESULTS: Respondents indicated that EBP is necessary and improves PHPR functions and tasks and that staff are interested in improving skills for EBP implementation. Top system-level barriers to EBP implementation were insufficient funding, lack of EBP, and lack of clarity regarding which practices are evidence based. PHEP awardees were significantly more likely to report a lack of EBP in the field, whereas LHDs were significantly more likely to report a lack of incentives. The top organizational-level barrier was insufficient staff. Most respondents indicated their agency culture supports EBP; however, LHDs were significantly more likely to report a lack of support from supervisors and leadership. Few respondents reported individual barriers to EBP implementation. CONCLUSIONS: Findings indicate an opportunity to improve dissemination strategies, communication efforts, and incentives to support EBP implementation in PHPR. Potential strategies include improving awareness of and accessibility to EBPs through targeted dissemination efforts; building organizational capacity to support EBP implementation, particularly staff capacity, knowledge, and skills; and identifying funding and incentives to promote EBP uptake and sustainment.
