Association between Freestanding Dialysis Facility Size and Medicare Quality Incentive Program Performance Scores

Area of Science:

• Nephrology and Healthcare Management
• Health Services Research
• Quality Improvement in Dialysis Care

Background:

• Medicare's Quality Incentive Program (QIP) penalizes underperforming dialysis facilities.
• Smaller, rural dialysis facilities often have lower profit margins, increasing their risk of penalties.
• The relationship between dialysis facility size and QIP scores was previously unknown.

Purpose of the Study:

• To investigate the association between freestanding dialysis facility size and Medicare QIP scores.
• To identify factors influencing QIP scores in relation to facility size.

Main Methods:

• Cross-sectional analysis of 5,193 freestanding dialysis facilities using 2015 Medicare data.
• Facility size measured by the number of dialysis stations.
• Generalized linear model used to analyze QIP scores, controlling for various facility and patient characteristics.

Main Results:

• Facilities with more than 10 dialysis stations achieved higher QIP scores compared to smaller facilities.
• Higher QIP scores were associated with facilities in the South/Northeast, not offering peritoneal dialysis, affiliated with most chains, and providing longer dialysis hours.
• Positive associations found with higher proportions of Hispanic patients and access to pre-end-stage renal disease (ESRD) nephrologist care; negative associations with higher Black patient populations and longer patient travel distances.

Conclusions:

• Dialysis facilities with 10 or fewer stations require targeted quality improvement strategies to avoid penalties and closure.
• Addressing disparities in ESRD care is crucial, particularly for smaller facilities.
• Financial insolvency due to penalties could exacerbate existing disparities in dialysis care.
