Rationale & objective:

Interdisciplinary care may improve health outcomes in patients with chronic kidney disease (CKD). Few studies have evaluated this model of health care delivery in racial and ethnic minorities.

Study design:

Retrospective cohort study.

Setting & participants:

Incident end-stage kidney disease (ESKD) patients at Montefiore Medical Center from October 1, 2013, to October 31, 2019.

Exposure:

Pre-ESKD interdisciplinary care.

Outcomes:

Pre-ESKD transplant listing and optimal kidney replacement therapy (KRT) start (use of arteriovenous access at hemodialysis initiation, outpatient hemodialysis start, preemptive transplant, or peritoneal dialysis as the first modality).

Analytical approach:

We constructed multivariable logistic regression models adjusted for sociodemographic and clinical factors to determine the odds of transplant listing and optimal KRT start between interdisciplinary versus the usual care group.

Results:

Of the 295 incident ESKD patients included in our study, 84 received interdisciplinary care and 211 received usual nephrology care. The mean age was 59.9 years (standard deviation, 13.9 years), 47% were women, and 87% were African American or Hispanic. Baseline characteristics were similar between the groups, except that the interdisciplinary care group had a lower prevalence of hypertension (60% vs 75%). Compared with usual care, a higher proportion of patients in the interdisciplinary care group were listed for kidney transplant (44% vs 16%) and had an optimal KRT start (53% vs 44%). Receipt of interdisciplinary care was associated with a higher odds (OR, 5.73; 95% CI, 2.78-11.80; P < 0.001) of transplant listing compared with usual care after adjusting for important sociodemographic and clinical factors. The odds of an optimal KRT start also favored interdisciplinary care (OR, 1.60; 95% CI, 0.88-2.89; P = 0.12) but did not achieve statistical significance.

Limitations:

The study was non-randomized and had a small sample size.

Conclusions:

Interdisciplinary care is associated with better ESKD preparedness compared with usual nephrology care alone in racial and ethnic minorities. Larger studies are needed to determine the effectiveness of interdisciplinary care in patients with advanced CKD.
