Objectives

Acute kidney injury (AKI) and acute kidney disease (AKD) are a continuum on a disease spectrum and frequently progress to chronic kidney disease. Benefits of nephrologist subspecialty care during the AKD period after AKI are uncertain.

Methods

Patients with AKI requiring dialysis who subsequently became dialysis independent and survived for at least 90 days, defined as the AKD period, were identified from the Taiwanese population’s health insurance database. Cox proportional hazard models using death as the competing risk before and after propensity-score matching were applied to evaluate various endpoints.

Results

Among a total of 20 260 patients with AKI requiring dialysis who became dialysis independent, only 7550 (37.3%) patients were followed up with by a nephrologist (F/U group) during the AKD period. During a mean 4.04 ± 3.56 years of follow-up, the patients in the F/U group were more often administered statin, antihypertensives, angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB), diuretics, antiplatelet agents, and antidiabetic agents. The patients in the F/U group had a lower mortality rate (hazard ratio [HR] = 0.87, P .001), and severe sepsis (sHR = 0.88, P = .008) according to the Cox proportional model after adjusting for mortality as a competing risk. During the AKD period, an increase in the frequency of nephrology visits was associated with improved outcomes.

Conclusions

In this population-based cohort, even after weaning off acute dialysis, only a minority of patients visited a nephrologist during the AKD period. We showed that nephrology follow-up is associated with a decrease in MACE, CHF exacerbations, and sepsis, as well as lower mortality; thus it may improve outcomes in patients with AKD.
