Implementation Facilitation of Exercise is Medicine Greenville

There is great potential for promoting physical activity (PA) for chronic disease prevention and treatment through the health care sector. Research has demonstrated effectiveness in assessing patient PA levels, providing 'exercise prescriptions', and referring patients to evidence-based PA programs in community settings. However, implementation barriers exist, ranging from practice integration to information flow, resulting in no major health systems integrating PA as part of a comprehensive approach to patient care. In 2016, a multi-organizational partnership between a large academic healthcare system, an academic institution, and a national PA organization launched Exercise is Medicine Greenville (EIMG), a comprehensive clinic-to-community approach that involves PA assessment, prescription, and referral of patients with chronic diseases to a tailored, community-based PA program. Since 2016, EIMG has expanded to 35 Prisma Health primary care clinics and 7 community PA facilities covering >400 square miles. Despite referring >1900 patients to date, great variability exists across participating clinics in correctly identifying eligible patients and providing EIMG referrals, reducing the overall reach and efficiency of engaging patients in the community-based PA programs. Using a pragmatic, stepped wedge, cluster randomized design, this research will examine the impact of implementation facilitation (IF) on improving the implementation and reach of EIMG with patients visiting participating Prisma Health primary care clinics. At six-month intervals, 35 randomly selected clinics (6 clinics in wave 1, 8 clinics in wave 2, 10 clinics in wave 3, and 11 clinics in wave 4) will receive IF planning (3 months), active IF (6 months), and post-IF maintenance (min 12 months). The specific aims of this project are to: 1) determine differences in the level of implementation (i.e., delivery fidelity) and reach (i.e., number, proportion, representativeness of patients) at Prisma primary care health clinics before and after IF, 2) assess levels of patient engagement in and the effectiveness of the 12-week, community-based PA programs, and 3) evaluate the costs of IF and the effects of increased EIMG referrals to the community-based PA program on patients costs and clinical outcomes. The mixed methods evaluation approach is guided by the RE-AIM framework to inform the assessment of implementation outcomes, and the i-PARIHS framework to describe contextual factors (i.e., determinants) influencing patient and clinic level outcomes. Through this work, the research will identify successful IF strategies across heterogeneous health settings, helping to identify and address potential disparities in the types of patients that receive EIMG referrals, are engaged in the EIMG referral pathway, and enroll and complete the community-based PA program. Study findings will provide important information on improving future implementation and scalability of PA integration in large health systems, optimizing clinic-community linkages, and the cost savings related to primary and secondary prevention of cardiovascular disease-related health outcomes in the general patient population.

The primary aim of this study is implementation facilitation at the clinic level. The secondary aim of this study is at the patient level. Therefore we have divided our inclusion/exclusion eligibility criteria by primary and secondary aim.

• pulmonary embolism
• venous embolism and thrombosis
• history of falling
• acute fracture
• left ventricular failure
• congestive heart failure
• hypertensive urgency, emergency or crisis
• diabetes with ketoacidosis
• chronic respiratory failure
• dependence on supplemental oxygen
• myocardial infarction

For patients completing accelerometry data collection, the additional inclusion/exclusion criteria apply:

Inclusion criteria

• Received an EIMG referral and scheduled for orientation
• Attending orientation at two pre-determined community PA facilities (these sites were selected due to each being the largest urban and rural YMCA referral sites in the study)

Exclusion criteria

• Unable to provide verbal informed consent
• Planning on travel or vacation during data collection, as patient PA behavior is anticipated to differ from 'everyday' PA behavior at home
• Unable to wear a watch during work hours due to employment restrictions e.g., food service, healthcare, operating heavy machinery/construction, laboratory-based work etc.

In addition, for patients completing interviews, the additional inclusion/exclusion criteria apply:

Inclusion criteria

• Received an EIMG referral

Exclusion criteria

• Unable to provide verbal informed consent
• Unable to speak or understand English
• <18 years of age
