Type 2 Diabetes Risk in Older Adults Living in Social Housing: A Cross-Sectional Study

A Systematic Review of Methodologies and Outcome Measures of Mobile Integrated Health-Community Paramedicine Programs

INTRODUCTION

Mobile 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.

METHODS

The 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.

RESULTS

Our 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).

CONCLUSION

Most 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.

Health knowledge and self-efficacy to make health behaviour changes: a survey of older adults living in Ontario social housing

BACKGROUND

Older adults living in social housing are a vulnerable population facing unique challenges with health literacy and chronic disease self-management. We investigated this population's knowledge of cardiovascular disease and diabetes mellitus, and self-efficacy to make health behaviour changes (for example, physical activity). This study characterized the relationship between knowledge of health risk factors and self-efficacy to improve health behaviours, in order to determine the potential for future interventions to improve these traits.

METHODS

A cross-sectional study (health behaviour survey) with adults ages 55+ (n = 599) from 16 social housing buildings across five Ontario communities. Descriptive analyses conducted for demographics, cardiovascular disease and diabetes knowledge, and self-efficacy. Subgroup analyses for high-risk groups were performed. Multivariate logistic regressions models were used to evaluate associations of self-efficacy outcomes with multiple factors.

RESULTS

Majority were female (75.6%), white (89.4%), and completed high school or less (68.7%). Some chronic disease subgroups had higher knowledge for those conditions. Significant (p < 0.05) associations were observed between self-efficacy to increase physical activity and knowledge, intent to change, and being currently active; self-efficacy to increase fruit/vegetable intake and younger age, knowledge, and intent to change; self-efficacy to reduce alcohol and older age; self-efficacy to reduce smoking and intent to change, ability to handle crises, lower average number of cigarettes smoked daily, and less frequent problems with usual activities; self-efficacy to reduce stress and ability to handle crises.

CONCLUSIONS

Those with chronic diseases had greater knowledge about chronic disease. Those with greater ability to handle personal crises and intention to make change had greater self-efficacy to change health behaviours. Development of stress management skills may improve self-efficacy, and proactive health education may foster knowledge before chronic disease develops.
