Dialysis decision-making process by Chinese American patients at an urban, academic medical center: a retrospective chart review

Abstract

Background Clinical practice guidelines emphasize shared decision-making for kidney replacement treatment, yet little is known about the influence of cultural differences on that process. We undertook a retrospective chart review to explore the process and timing of dialysis decision making and initiation in Chinese American patients to provide quality kidney care for this population. Design Participants received outpatient care at Tufts Medical Center and dialysis at Dialysis Clinic, Inc. Boston or Somerville, MA from 2001–2021. Clinic chart review sourced demographic, clinical, and end-of-life care information from 180 participants (82 Chinese American, 98 other) from stage 4 chronic kidney disease (CKD) and dialysis initiation. Results Chinese American participants were older (mean 70 vs. 59, p < 0.0001), less likely to speak English (12% vs. 87%, p < 0.0001), and used interpreter services more (80% vs. 11%, p < 0.0001). Chinese American participants had more visits (median 14 vs. 10, p = 0.005); were more often accompanied by family members (75% vs. 40%, p < 0.001); and had significantly lower rates of healthcare proxy documentation (35% vs. 55%, p = 0.006). There was no statistical difference in months between first CKD 4 visit and first dialysis. Both groups started dialysis at the same average eGFR and with similar rates of permanent dialysis access. Chinese American participants had significantly lower serum albumin at dialysis initiation (mean 3.3 g/dL vs 3.7 g/dL, p = 0.0003). Documentation reflected a low number of conversations about non-dialytic care, end-of-life planning, or palliative care in both groups across all visits. Conclusion The time between CKD 4 and dialysis initiation was the same in both groups, suggesting a similar overall outcome of care. Chart documentation suggests that Chinese American participants had a significantly higher number of visits with nephrologists where discussion about dialysis was noted and were more likely to have a family member present at the visit. Fewer Chinese American participants completed healthcare proxies. Among all study participants, healthcare proxy, code status, and palliative care discussions were reported less frequently than expected. These findings highlight opportunities for collaboration between palliative care clinicians and nephrologists.
