Background
Patients on dialysis often suffer from muscle wasting and reduced exercise tolerance compared with the general population. The impact for this debility on the in-patient dialysis population remains unclear. The purpose of the current study was to determine the inpatient mortality and cost effects of debility between dialysis patients.
Methods
Data was extracted from the 2005 to 2012 Nationwide Inpatient Sample (NIS). Using propensity score matching, end stage renal disease (ESRD) patients with debility were matched with ESRD patients without debility at a 1:1 ratio. We compared inpatient mortality, length of stay and total hospital charges between both groups. Analyses were performed using SAS version 9.3 (SAS Institute, Cary, NC, USA).
Results
Among 1,070,450 hospitalized ESRD patients during 2005 to 2012; only 16,810 (1.57%) were identified with debility. These patients were associated with significantly higher rate of gastrointestinal bleed (2.01 vs 1.77%; p=0.02), obesity (11.92 vs 8.37%), acute CHF (39.12 vs 33.94%; p=0.0001), Atrial fibrillation (23.11 vs 15.06%; p=0.0001) and CAD (41.74 vs 33.99; p=0.0001). Surprisingly, ESRD patients with debility had a significantly lower in-hospital mortality compared with ESRD patients without debility before (4.52 vs 5.09%; p=0.001) and after matching (4.53 vs 6.17%, p = 0.0001). Mean length of stay for those with debility was 11.12 days compared with 7.53 days (p < 0.0001). Similarly, mean hospital charges were greater for those who had debility compared with control ($69,596 vs $57,752; p < 0.001).
Conclusion
Debility in dialysis patients appears to have a lower in hospital mortality compared to more conditioned ESRD patients. It does however increase the costs and length of stay. Interventions to lower debility may help reduce hospital expenditures.
