SAT-628 Risk Factors Associated with 30-Day and 90-Day Readmission in Persons with Diabetic Foot Ulcers

Background Diabetic foot ulcers (DFU) are the leading cause of lower-extremity amputations among patients with diabetes (DM)(1). 15% of patients with DM develop DFU, with the potential for progression to osteomyelitis or gangrene with suboptimal glycemic control. Repeated readmissions are not only a...

Sumario:Background Diabetic foot ulcers (DFU) are the leading cause of lower-extremity amputations among patients with diabetes (DM)(1). 15% of patients with DM develop DFU, with the potential for progression to osteomyelitis or gangrene with suboptimal glycemic control. Repeated readmissions are not only a negative prognostic indicator for these patients, but also contributes to increasing healthcare costs. Areas of Uncertainty Previous studies have examined associations among demographics, comorbidities and DFU, and the value of Hemoglobin A1c (HbA1c) and C-reactive protein (CRP) as a prognostic indicator and monitoring tool for progression and regression, respectively(3,4). However, no studies to date have examined medical or pharmaceutical factors contributing to 30-day and 90-day readmission. Methods A retrospective chart review was conducted examining 397 patients with type 2 diabetes readmitted for DFU between 2014 and 2019. Variables were summarized using descriptive statistics, t-tests, chi-square, and logistic regressions. Results Majority of patients were white males with a BMI over 30 and HbA1c >7%. Patients with 30-day readmission were more likely to be using anticoagulants (30.00% vs. 17.24%, p= 0.0493). Patients with 90-day readmission were more likely to be discharged home with healthcare services (55.67% vs. 39.85%, p=0.0341) or to a skilled nursing facility (7.22% vs. 6.02%, p=0.0341). Although not statistically significant, patients with both 30-day and 90-day readmissions were also more likely to have HbA1c >7, while those with a 90-day readmission had higher CRP levels. Conclusions DFU patients with suboptimal glycemic control were more likely to experience a 30-day and 90-day readmission. Predicators for readmission in this population include: anticoagulation use, discharge to a skilled nursing facility or discharge home with healthcare services. As a result, patients not on anticoagulation, as well as those discharged home without services or to rehabilitation facilities have a reduced risk of readmission. 1. Lazzarini PA, Clark D, Derhy PH.
