# Social Drivers of Health and Communication Interventions Impact Wound Care Follow-Up Adherence: A Retrospective Cohort Study at a Tertiary Care Center

## TL;DR

This study shows that communication before discharge and social factors significantly affect how well patients follow up on wound care, impacting readmission rates.

## Contribution

The study identifies pre-discharge communication as a novel intervention to improve wound care follow-up adherence.

## Key findings

- Patients who scheduled follow-up appointments had a 70.5% adherence rate.
- Lack of follow-up care was an independent predictor of hospital readmission.
- Older patients and skilled nursing facility residents had lower follow-up adherence.

## Abstract

Introduction: Chronic wounds affect approximately six million people in the United States. Despite established multidisciplinary wound care protocols, patient adherence to follow-up care remains suboptimal. We aimed to understand the impact of social drivers of health on patient decision-making for improving wound care follow-up adherence. Methods: We conducted a retrospective review of all hospitalized patients who consulted in-house wound care staff at a tertiary care center between August 2017 and June 2020, regardless of primary admission diagnosis. Referred patients received standardized care from a multidisciplinary team at an outpatient wound care facility. Primary endpoints were pre-discharge scheduling and follow-up rates. Follow-up efficacy was assessed through 90-day hospital readmission rates. Results: Of 444 patients, 205 (46.2%) were readmitted or expired within 90 days. Adjusted analysis identified lack of follow-up care reception as an independent predictor of hospital readmission (hazard ratio 2.39; 95% CI, 1.45–3.89; p < 0.001). Among 156 (35.1%) patients who scheduled follow-up, 110 (70.5%) adhered to their appointment. Patients not scheduling follow-up were older (median age 79 vs. 70 years, p < 0.001), longer hospital stays (median 9 vs. 6 days, p < 0.0001), and more frequently discharged to skilled nursing facilities (47.6% vs. 26.3%, p < 0.0001). Among scheduled patients, skilled nursing home residents demonstrated lower follow-up adherence (OR 0.3; 95% CI, 0.14–0.65; p < 0.01). Conclusions: Pre-hospital discharge communication for scheduling follow ups serves as a critical intervention point in patient decision-making for wound follow-up. Considering the limitations of a retrospective single-center study, we find that pre-discharge education about follow-up scheduling for high-risk groups, including patients ≥ 80 years and skilled nursing facility residents, may improve follow-up adherence and reduce readmissions.
