Evaluation of the Paramedic Evaluation for Acute COPD Exacerbation

Chronic Obstructive Pulmonary Disease (COPD) is a serious lung condition that affects millions of people in the United States. Each year, it leads to about 150,000 deaths, nearly 900,000 emergency room visits, and 700,000 hospital stays. When COPD symptoms suddenly get worse-called an exacerbation-it can seriously harm a person's quality of life and often requires emergency care. Treating these flare-ups early can help prevent hospital visits, but right now, there aren't many good ways to make sure people get care quickly. Mobile Integrated Health (MIH) programs send specially trained paramedics, guided remotely by doctors, to care for patients in their homes. This approach could help people with COPD get faster, more effective care without needing to go to the hospital. In this project, the investigators are testing a new program called PEACE (Paramedic Evaluation for Acute COPD Exacerbation). The PEACE program sends community paramedics to patients' homes-when needed and in partnership with their regular doctors-to manage worsening COPD symptoms early. The study team will adapt the PEACE program to meet the needs of adults living at home with moderate to severe COPD, gather feedback from patients and healthcare providers, and run a small pilot study to see if the program is practical and helpful.

Evidence-based strategies to ensure that patients with COPD have reliable, timely, equitable access to treatment are lacking. This deficit is particularly evident in communities impacted by determinants of health that adversely impact preventive health behavior and care access. On-demand Mobile Integrated Health (MIH) teams, comprised of community paramedics supported by centralized physicians, have been developed to care for patients outside of conventional hospital settings. These teams empower physicians to provide enhanced remote care by collecting essential clinical information about patients in their living environment, performing diagnostic testing, and administering therapy in the home. MIH programs decrease emergency medical services utilization and improve patient satisfaction in select populations, but the impact of MIH programs on the outcomes of patients with COPD exacerbation has not been evaluated. In this project, the study team will implement and refine an MIH intervention for patients living with COPD. The Paramedic Evaluation for Acute COPD Exacerbation (PEACE) intervention will dispatch community paramedics to execute a home-based evaluation and treatment strategy in collaboration with a supervising physician and the patient's ambulatory medical team during and after acute COPD exacerbation to promote wellness and recovery. This intervention is intended to improve clinical outcomes and reduce acute care costs by eliminating barriers to care, generating actionable clinical data that can facilitate appropriate diagnosis, accelerating treatment, and simplifying care coordination. Our central hypothesis, based on preliminary data and input from key informants, is that an intervention that facilitates community-based management of COPD exacerbation will be acceptable and highly adoptable by patients and clinicians. The Practical Robust Implementation and Sustainability Model (PRISM) implementation framework will be used to describe factors impacting project implementation, with the embedded Expanded RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) model guiding outcomes measurements. Leveraging our prototypical intervention design, the study team will test and Refine the prototype PEACE intervention in real clinical practice with a cohort of patients who are at high risk of COPD exacerbation. The study team will use a mixed-methods approach to evaluate the usability and acceptability of each operational and clinical component of PEACE. Measures will include a systematic assessment of protocol adherence, survey instruments, and qualitative interviews to explore contextual factors impacting intervention performance. The study team will confirm our findings and adapt the protocols informed by a working group comprised of clinicians and community partners. Up to 25 patient participants will be enrolled in the intervention, plus up to 11 clinician participants will be enrolled to participate in usability/acceptability ratings and qualitative evaluations/focus groups.
