Symptoms in the month before death for stage 5 chronic kidney disease patients managed without dialysis.

CONTEXT

There is little evidence on the symptoms experienced by those with advanced (Stage 5) chronic kidney disease (CKD), managed without dialysis, as they approach death. As palliative care extends to noncancer illnesses, understanding symptom prevalence and severity close to death will clarify which symptom interventions are most needed and which elements of (largely cancer-driven) models of palliative care best translate into end-of-life care for this population.

OBJECTIVES

To determine symptom prevalence and severity in the last month of life for patients with Stage 5 CKD, managed without dialysis.

METHODS

Longitudinal symptom survey in three U.K. renal units, using the patient-completed Memorial Symptom Assessment Scale-Short Form (MSAS-SF). We calculated the prevalence of individual symptoms (with 95% confidence intervals [CI] to reflect sample size), plus MSAS-SF subscales, in the month before death. Comparison is made with previously published data on symptoms in the last month of life in advanced cancer, also measured using the MSAS-SF.

RESULTS

Seventy-four patients (mean age: 81 years; standard deviation [SD]: 6.8) were recruited (response rate: 73%); 49 (66%) died during follow-up (mean age: 81 years; SD: 5.7). "Month before death" symptom data were available for 43 (88%) of the 49 participants who died. Median time of data collection was 18 days from death (interquartile range: 12-26 days). More than half had lack of energy (86%; 95% CI: 73%-94%), itch (84%; 70%-93%), drowsiness (82%; 68%-91%), dyspnea (80%; 66%-90%), poor concentration (76%; 61%-87%), pain (73%; 59%-85%), poor appetite (71%; 57%-83%), swelling arms/legs (71%; 57%-83%), dry mouth (69%; 55%-82%), constipation (65%; 50%-78%), and nausea (59%; 44%-73%). Levels of distress correspond to prevalence, with the exception of dyspnea, which was disproportionately more distressing. The median number of symptoms reported was 16.6 (range: 6-27), rising to 20.4 (range: 7-34) if additional renal symptoms were included. On average, psychological distress was moderate (mean MSAS-PSYCH: 1.55) but with wide variation (SD: 0.50; range: 0.17-2.40), suggesting diverse levels of individual distress. The prevalence of both physical and psychological symptoms and the number reported were higher than those in advanced cancer patients in the month before death.

CONCLUSION

Stage 5 CKD patients have clinically important physical and psychological symptom burdens in the last month of life, similar or greater than those in advanced cancer patients. Symptoms must be addressed through routine symptom assessment, appropriate interventions, and with pertinent models of end-of-life care.
