Patient-focused outcomes after initiation of dialysis for ESRD: mortality, hospitalization and functional impairment.

BACKGROUND

Outcome data regarding clinically relevant endpoints after starting dialysis for end-stage renal disease (ESRD) are sparse, and early events after starting dialysis are particularly underestimated. The aim of this study was to describe patient-focused outcomes in ESRD patients starting from first dialysis.

METHODS

The data basis for this retrospective observational study were anonymized healthcare data from Germany's largest statutory health insurer. We identified ESRD patients who initiated dialysis in 2017. Deaths, hospitalizations and occurrence of functional impairment within 4 years after starting dialysis were recorded starting from first treatment. Hazard ratios in dialysis patients compared with an age- and sex-matched reference population without dialysis were generated, stratified by age.

RESULTS

The dialysis cohort included 10 328 ESRD patients who started dialysis in 2017. First dialysis was performed in-hospital for 7324 patients (70.9%), and 865 of these died during the same hospitalization. One-year mortality for ESRD patients initiating dialysis was 33.8%. Functional impairment occurred in 27.1% of patients, while 82.8% of patients required hospitalization within 1 year. Hazard ratios of dialysis patients compared with the reference population for mortality, functional impairment and hospitalization at 1-year were 8.6, 4.3 and 6.2. Dialysis patients <50 years were disproportionately affected, with >40-fold increased risk of adverse events compared with their peers.

CONCLUSIONS

The emergence of morbidity and mortality after starting dialysis for ESRD is significant, especially in younger patients. Patients have a right to be informed about the prognosis associated with their condition.
