Background

Dialysis recovery time (DRT) is the perceived time it takes patients to recover their ability to undertake daily activities after hemodialysis (HD). DRT is a meaningful variable to assess health related quality of life (HRQOL) in HD patients. As such, DRT as a predictor of hospitalization could be looked at as an early indicator of treatment success or impending morbidity. We characterized the hospital admission rates based on DRT categories among incident HD patients treated at a large dialysis organization (LDO).

Methods

We used data at an LDO during 2014 through 2017 for patients who completed a DRT survey ≤180 from first date of HD. DRT survey was administered as part of KDQOL questionnaire. DRT survey asks: “How long does it take you to be able to return to your normal activities after your dialysis treatment?”. Categorical answers were: <0.5, 0.5-1, 1-2, 2-4, >4 hours. Hospital admission rates were compared by DRT category (DRT <0.5 hour reference) via unadjusted Poisson models.

Results

We included data from 98616 incident HD patients (age 62.6±14.4 years; 57.8% male). There were 25.2%, 19.1%, 17.3%, 15.5%, and 22.9% of HD patients reporting a DRT of <0.5, 0.5-1, 1-2, 2-4, and >4 hours, respectively. We observed 6-, 12-, and 24-month crude admission rates of patients rose with each longer DRT category (all p<0.001), as compared to patients with a DRT <0.5 hour (Figure 1).

Conclusion

Findings suggest longer DRTs in incident HD may associate with progressive increases in crude short- and long-term admission rates. DRT is an important marker of how well the patient feels and tolerates HD therapy. Optimizing the HD treatment around DRT in the incident period may have the ability to improve HRQOL and outcomes.
