Questionnaire survey on the prescription of renal replacement therapy for acute phase patients on maintenance dialysis who developed cerebrovascular disease.

BACKGROUND

There is limited information about acute phase renal replacement therapy (RRT) for maintenance hemodialysis patients after the onset of cerebrovascular disease. This study aimed to investigate which modality of renal replacement therapy is currently selected in practice.

METHODS

We conducted a mail-based survey in 317 dialysis facilities that were certified by three academic societies that focus on dialysis, neurology, and neurosurgery in Japan.

RESULTS

We received responses from 103 facilities (32.5%). In cases of cerebral infarction (CI) and intracerebral hemorrhage (ICH), more than 80% of the facilities selected only intermittent RRT, and 22.3% (CI)/8.7% (ICH) of the facilities selected intermittent HD which is the same setting in normal conditions. Although continuous hemodiafiltration and peritoneal dialysis are recommended in the Japanese guidelines, these were selected in only a few facilities: 16.5% and 0% in CI, 16.5% and 1% in ICH, respectively. RRT on the day of onset tended to be avoided, irrespective of the duration following the last HD session. Furthermore, physicians preferred to modify anticoagulants and reduce dialysis performance in the acute phase.

CONCLUSION

This questionnaire survey uncovered a gap between guidelines and actual practice, even in hospitals accredited as educational facility, which is a novel and important finding. Further studies with larger sample sizes are needed to determine the optimal modality of RRT for the acute phase of cerebrovascular disease.
