Background
Many dialysis patients receive intensive procedures intended to prolong life at the very end of life. However, little is known about trends over time in use of these procedures. We describe temporal trends in receipt of inpatient intensive procedures during the last six months of life among patients treated with maintenance dialysis.
Study Design
Mortality follow-back study.
Setting & Participants
649,607 adult Medicare beneficiaries on maintenance dialysis who died in 2000–2012.
Predictors
Time period of death (2000–2003, 2004–2008, or 2009–2012), age at the time of death (18–59, 60–64, 65–69, 70–74, 75–79, 80–84 and ≥ 85 years) and race/ethnicity (Hispanic, non-Hispanic Black, or non-Hispanic White).
Outcome
Receipt of an inpatient intensive procedure (defined as invasive mechanical ventilation/intubation, tracheostomy, gastrostomy/jejunostomy tube insertion, enteral or parenteral nutrition, or cardiopulmonary resuscitation) during the last six months of life.
Results
Overall, 34% of cohort patients received an intensive procedure in the last six months of life, increasing from 29% in 2000 to 36% in 2012 (with 2000–2003 as the referent category, adjusted risk ratios [RRs] were 1.06 [95% CI, 1.05–1.07] and 1.10 [95% CI, 1.09–1.12] for 2004–2008 and 2009–2012, respectively). Use of intensive procedures increased more markedly over time in younger versus older patients (comparing 2009–2012 to 2000–2003, the adjusted RR was 1.18 [95% CI, 1.15–1.20] for the youngest age group, as opposed to 1.00 [95% CI, 0.96–1.04] for the oldest age group). Comparing 2009–2012 to 2000–2003, the use of intensive procedures increased more dramatically for Hispanic patients than for non-Hispanic Black or non-Hispanic White patients (adjusted RRs of 1.18 [95% CI, 1.14–1.22], 1.09 [95% CI, 1.07–1.11], and 1.10 [95% CI, 1.08–1.12], respectively).
Limitations
Data sources do not provide insight into reasons for observed trends in use of intensive procedures.
Conclusions
Among patients treated with maintenance dialysis, there is a trend toward more frequent use of intensive procedures at the end of life, especially in younger patients and those of Hispanic ethnicity.
