Addressing healthcare disparities and improving osteoporosis management in rural communities: a cluster randomized control trial

Abstract

Summary

Rural communities face healthcare challenges. This study assessed a multicomponent intervention to improve hospital visits and anti-osteoporosis medication (AOM) treatment rates. A total of 567 patients were randomized into three groups. Results showed significant improvements in hospital attendance and AOM treatment in intervention groups compared to usual care group.

Purpose

Rural communities face limited healthcare access, financial constraints, and transportation barriers leading to health disparities. This study examined interventions that reduced health disparities in increasing the outpatient attendance and treatment rate of anti-osteoporosis medication (AOM), while identifying factors contributing to therapy refusal in rural communities.

Methods

A total of 567 patients were randomized at the community level into three groups: multicomponent integrated care (MIC), osteoporosis care only (OC), and usual care (UC). Fracture Risk Assessment Tool and dual-energy X-ray absorptiometry scans were used to evaluate the osteoporosis and osteoporotic fracture risk. High- and moderate-risk patients were advised to pursue further hospital-based assessments and treatment. Both the MIC and OC groups received five interventions to address rural barriers, including specialist access, disease education, overcoming transportation barriers, peer support, and dedicated case managers. However, UC excluded transportation assistance, peer support, and case management. Outcomes measured included outpatient attendance, AOM treatment rates, and factors affecting hospital assessment refusal, analyzed via multivariable logistic modeling.

Results

In the MIC group, 73.3% of patients attended the outpatient clinic and 58.6% received AOM. In the OC group, 81% patients attended and 69.3% received AOM. Conversely, in the UC group, only 4.1% attended and received AOM. Significant differences in attendance and AOM rates were found between the MIC and UC groups and between the OC and UC groups (p < .001 for both). Common barriers included beliefs that treatment was unnecessary and lack of hospital access. Risk factors hindering outpatient attendance include male sex, low education, low budget, multiple disabilities, and osteopenia diagnosis.

Conclusion

Addressing transportation barriers and implementing dedicated case management are crucial for improving healthcare access among rural patients.
