IntroductionMobile integrated health-community paramedicine (MIH-CP) uses patient-centered, mobile resources in the out-of-hospital environment to increase access to care and reduce unnecessary emergency department (ED) usage. The objective of this systematic review is to characterize the outcomes and methodologies used by MIH-CP programs around the world and assess the validity of the ways programs evaluate their effectiveness.MethodsThe PubMed, Embase, CINAHL, and Scopus databases were searched for peer-reviewed literature related to MIH-CP programs. We included all full-length studies whose programs met the National Association of Emergency Medical Technicians definition, had MIH-CP-related interventions, and measured outcomes. We excluded all non-English papers, abstract-only, and incomplete studies.ResultsOur initial literature review identified 6434 titles. We screened 178 full-text studies to assess for eligibility and identified 33 studies to include in this review. These 33 include four randomized controlled trials, 17 cohort studies, eight 8 case series, and four 4 cross-sectional studies. Of the 29 non-randomized trials, five used matched controls, 13 used pre-post, and 11 used no controls. Outcomes measured were hospital usage (24 studies), ED visits (15), EMS usage (23), patient satisfaction (8), health-related outcomes (8), and cost (9). Studies that evaluated hospital usage reported one of several outcome measures: hospital admissions (11), ED length of stay (3), and hospital readmission rate (2). EMS usage was measured by ambulance transports (12) and EMS calls (10). Cost outcomes observed were ambulance transport savings (7), ED visit savings (4), hospital admission savings (3), and cost per quality-adjusted life year (2).ConclusionMost studies assessing MIH-CP programs reported success of their interventions. However, significant heterogeneity of outcome measures and varying quality of study methodologies exist among studies. Future studies designed with adequately matched controls and applying uniform core metrics for cost savings and health care usage are needed to better evaluate the effectiveness of MIH-CP programs.
