Factors Associated With Hospital Readmissions Among U.S. Dialysis Facilities

The Centers for Medicare and Medicaid uses the standardized readmission ratio (SRR) to evaluate 30-day readmissions among dialysis providers in the U.S. Readmissions among dialysis recipients remains 37%. This study investigates associations among dialysis facilities and patient characteristics with facility's performance on the SRR.

Descriptive, longitudinal, approach using multivariate regression analysis on data retrieved from the Dialysis Facility Report to evaluate the associations between facility-level (staffing, profit status, chain membership, clinic size, care, length of care, vascular access type, glomerular filtration rate (GFR), creatinine, hemoglobin, use of erythropoietin-stimulating agent, albumin, and primary dialysis modality) with the SRR.

Factors associated with a high SRR included nurse ratios, facility average GFR, and Northeast geographic location. Factors associated with a low SRR included patient care technician ratio, length of predialysis nephrology care, initiation of dialysis with an arteriovenous fistula, average hemoglobin, and Western geographic location.

This study defines the influence predialysis nephrology care has on dialysis facilities SRRs. Access to care, adequate preparation for dialysis, and transitional support affect facilities' performance; however, without an appropriate staffing model, dialysis facilities may continue to struggle to reduce readmissions.
