Dissemination and Implementation of Improving Pediatric Obesity Practice Using Prompts

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the dissemination and implementation of electronic health record-based clinical decision support tools for the management of pediatric overweight and obesity in primary care.

Detailed Description
-----------------
This study will evaluate iPOP-UP, a newly-optimized intervention to improve adherence to national guidelines for the management of childhood obesity, among 84 primary care practices affiliated with three health systems serving children with racial and ethnic, socio-economic, rural-urban, and geographic diversity. This multi-site, parallel 2-arm cluster randomized controlled Hybrid Type 2 effectiveness-implementation trial will use mixed methods (electronic health record (EHR) data analysis, surveys, interviews, and focus groups) to simultaneously evaluate (1) the effectiveness of the iPOP-UP implementation package in improving clinical care and children's BMI outcomes in pediatric primary care setting and (2) the impact of the implementation strategy on the reach, adoption, fidelity, cost, and maintenance of the intervention. The unit of randomization in this study is pediatric primary care practices. Within the participating 84 practices, pediatric primary care clinicians working at the implementation sites will be invited to participate in pre- and post-intervention surveys assessing their practice behaviors, obesity-related attitudes, beliefs, and self-efficacy, EHR usage and attitudes, and training preferences. In addition, a limited data set of EHR from patients visits will be queried and analyzed to evaluate clinical care outcomes and children's BMI outcomes. Limited data (to include dates and geographic information but no facial identifiers) will be queried and analyzed for all children 1) age 2.0 to ≤18 years-old at baseline, 2) with a well-child visit, during which height and weight are measured, at one of the participating practices during the study period, and 3) with a BMI ≥85th percentile for age/sex (CDC criteria for overweight/obesity). Outcomes include: (a) change in BMI, measured as the yearly change in BMI expressed as a percentage of the 95th percentile (%BMIp95); (b) Change in clinicians' objective practice around managing elevated BMI in primary care using EHR data; (c) Change in clinicians' self-reported knowledge, attitudes, and practice around managing elevated BMI in primary care; and (d) Utilization of Clinical Decision Support (CDS) tools. The investigators will also describe implementation outcomes (reach, adoption, fidelity/adaptation, and cost) through qualitative and quantitative data collection from members of the study team throughout the process of implementation.

Arms and Interventions

| Experimental: Clinical Decision Support Tool<br>Practices assigned to iPOP-UP intervention which involves EHR-based CDS tools refined through a formative evaluation and user-centered design. | Behavioral: Improving Pediatric Obesity Practice Using Prompts (iPOP-UP)<br>* EHR-based CDS tools refined through a formative evaluation and user-centered design process that immediately preceded this study.<br>|
| No Intervention: Control<br>Practices assigned to usual care that will not have access to the iPOP-UP CDS tool but will have access to many opportunities available to all pediatric clinicians nationally around the release of the new American Academy of Pediatrics guidelines for obesity management. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in %BMIp95 | Change in %BMIp95, calculated from height and weight measured as part of routine clinical practice during primary care clinic visits and documented in the electronic health record. A negative percentage indicates that the participant's BMI has decreased since trial launch. | Up to 15 months after first primary care visit following trial launch | 
| Change in composite measure of clinician's adherence to clinical guidelines, for visits completed among children 2-18 years-old with BMI ≥85th percentile. | Six-month change in composite measure of adherence to clinical guidelines, calculated from practice behaviors queried from the electronic health record. A dichotomous variable, adherence is defined as whether or not, for each relevant visit, the clinician followed all evidence of recommended obesity-related care during the study period: Inclusion of diagnosis code indicating high BMI in visit diagnosis associated with the visit or as an active diagnosis in the problem list Recommended lab orders for obesity related comorbidities, if eligible Appropriate BP measurement in children 3 and older Counseling diagnosis codes or structured documentation (every visit) Follow-up visit requested at visit or active referral order for further management of obesity A score of 1 indicates that a clinician followed all evidence of recommended obesity-related care; a score of 0 indicates that a clinician did not follow at least one recommendation for obesity-related care. | Baseline through 6 months after trial launch | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in composite measure of clinician's adherence to clinical guidelines | Change from baseline through 12 and 18 months in composite measure of adherence to clinical guidelines, calculated from practice behaviors queried from the electronic health record. A dichotomous variable, adherence is defined as whether or not, for each relevant visit, the clinician followed all evidence of recommended obesity-related care during the study period: Inclusion of diagnosis code indicating high BMI in visit diagnosis associated with the visit or as an active diagnosis in the problem list Recommended lab orders for obesity related comorbidities, if eligible Appropriate BP measurement in children 3 and older Counseling diagnosis codes or structured documentation (every visit) Follow-up visit requested at visit or active referral order for further management of obesity A score of 1 indicates that a clinician followed all evidence of recommended obesity-related care; a score of 0 indicates that a clinician did not follow at least one recommendation | Baseline through 18 months after trial launch |

| Change in appropriate blood pressure screening in children 3 and older | Visits completed among children 3-18 years with BMI ≥85th percentile during the study period with evidence of appropriate blood pressure screening queried from the electronic health record. A higher proportion of visits with blood pressure screening is consistent with recommended care. | Baseline through 18 months after trial launch | 
| Change in structured documentation of counseling | Visits completed among children 2-18 years with BMI ≥85th percentile during the study period with evidence of counseling structured documentation queried from the electronic health record.
