Association Between Pre-Dialysis Nephrology Care Duration and Short-Term Outcomes in Hemodialysis Patients.

INTRODUCTION

Despite recommendations for early nephrology referral in CKD stage G4+, emergency dialysis remains common.

METHODS

This retrospective study evaluated whether pre-dialysis nephrology care duration influences outcomes after initiation. We analyzed 388 hemodialysis patients (2014-2022), divided into Short (< 3 months) and Long (> 6 months) care groups. Clinical and socioeconomic factors were compared using Fisher's exact test, Mann-Whitney U test, and Kaplan-Meier analysis.

RESULTS

The proportion of Short Group patients did not decline over time. Ninety-day survival was significantly lower in the Short Group (p < 0.01). The Long Group had more comorbidities, such as hypertension and diabetes, likely reflecting earlier referral. The Short Group had longer hospital stays, more tunneled catheter use, and fewer AVF placements.

CONCLUSION

These findings suggest that nephrology care exceeding 6 months before dialysis may improve short-term survival. Promoting earlier referral of patients with CKD could reduce emergency dialysis and enhance patient outcomes.
