Depressive affect in incident hemodialysis patients.

ABSTRACT: Background:The prevalence of depressive affect is not well defined in the incident hemodialysis (HD) population. We investigated the prevalence of and associated risk factors and hospitalization rates for depressive affect in incident HD patients. Methods:We performed a prospective investigation using the Patient Health Questionnaire 2 (PHQ2) depressive affect assessment. From January to July of 2013 at 108 in-center clinics randomly selected across tertiles of baseline quality measures, we contacted 577 and 543 patients by telephone for depressive affect screening. PHQ2 test scores range from 0 to 6 (scores ??3 suggest the presence of depressive affect). The prevalence of depressive affect was measured at 1-30 and 121-150 days after initiating HD; depressive affect risk factors and hospitalization rates by depressive affect status at 1-30 days after starting HD were computed. Results:Of 1120 contacted patients, 340 completed the PHQ2. In patients screened at 1-30 or 121-150 days after starting HD, depressive affect prevalence was 20.2% and 18.5%, respectively (unpaired t-test, P?=?0.7). In 35 patients screened at both time points, there were trends for lower prevalence of depressive affect at the end of incident HD, with 20.0% and 5.7% of patients positive for depressive affect at 1-30 and 121-150 days, respectively (paired t-test, P?=?0.1). Hospitalization rates were higher in patients with depressive affect during the first 30 days, exhibiting 1.5 more admissions (P?

Project description:In the general population, low serum magnesium levels are associated with poor outcomes and death. While limited data suggest that low baseline magnesium levels may be associated with higher mortality in hemodialysis (HD) patients, the impact of changes in magnesium levels over time is unknown.We examined the association of time-varying serum magnesium levels with all-cause mortality using multivariable time-varying survival models adjusted for clinical characteristics and other time-varying laboratory measures.9,359 maintenance HD patients treated in a large dialysis organization between 2007 and 2011.Time-varying serum magnesium levels across 5 magnesium increments (<1.8, 1.8-<2.0, 2.0-<2.2, 2.2-<2.4, and ?2.4mg/dL).All-cause mortality.2,636 individuals died over 5 years. Time-varying serum magnesium levels < 2.0mg/dL were associated with higher mortality after adjustment for demographics and comorbid conditions, including hypertension, diabetes, and malignancies (reference: magnesium, 2.2-<2.4mg/dL): adjusted HRs for serum magnesium level < 1.8 and 1.8 to <2.0mg/dL were 1.39 (95% CI, 1.23-1.58; P<0.001) and 1.20 (95% CI, 1.06-1.36; P=0.004), respectively. Some associations were attenuated to the null after incremental adjustment for laboratory test results, particularly serum albumin. However, among patients with serum albumin measurements, low albumin level (<3.5g/dL) and magnesium level < 2.0mg/dL were associated with an additional death risk (adjusted HR, 1.17; 95% CI, 1.05-1.31; P=0.004), whereas patients with high serum albumin levels (?3.5g/dL) exhibited low death risk (adjusted HRs of 0.53 and 0.53 [P?0.001] for magnesium < 2.0 and ?2.0mg/dL, respectively; reference: albumin < 3.5g/dL and magnesium ? 2.0mg/dL).Causality cannot be determined, and residual confounding cannot be excluded given the observational study design.Lower serum magnesium levels are associated with higher mortality in HD patients, including those with hypoalbuminemia. Interventional studies are warranted to examine whether correction of hypomagnesemia ameliorates adverse outcomes in this population.
