Impact of admission serum calcium levels on mortality in hospitalized patients.

OBJECTIVES: To assess the relationship between admission serum calcium levels and in-hospital mortality in all hospitalized patients. METHODS: All adult hospitalized patients who had admission serum calcium levels available between years 2009 and 2013 were enrolled. Admission serum calcium was categorized based on its distribution into six groups (<7.9, 7.9 to <8.4, 8.4 to <9.0, 9.0 to <9.6, 9.6 to <10.1, and ≥10.1 mg/dL). The odds ratio (OR) of in-hospital mortality by admission serum calcium, using the calcium category of 9.6-10.1 mg/dL as the reference group, was obtained by logistic regression analysis. RESULTS: 18,437 patients were studied. The lowest incidence of in-hospital mortality was associated with admission serum calcium within 9.6 to <10.1 mg/dL. A higher in-hospital mortality rate was observed in patients with serum calcium <9.6 and ≥10.1 mg/dL. Also, 38% and 33% of patients with admission serum calcium <7.9 and ≥10.1 mg/dL were on calcium supplements before admission, respectively. After adjusting for potential confounders, both serum calcium <8.4 and ≥10.1 mg/dL were associated with an increased risk of in-hospital mortality with ORs of 2.86 [95% confidence interval (CI) 1.98-4.17], 1.74 (95% CI 1.21-2.53), and 1.69 (95% CI 1.10-2.59) when serum calcium were within <7.9, 7.9 to <8.4, and ≥10.1 mg/dL, respectively. CONCLUSION: Hypocalcemia and hypercalcemia on admission were associated with in-hospital mortality. Highest mortality risk is observed in patients with admission hypocalcemia (<7.9 mg/dL). One-third of patients with hypercalcemia on admission were on calcium supplements.

Practice patterns of phosphate binder use and their associations with mortality in chronic kidney disease.

BACKGROUND: Higher serum phosphorus is associated with an increased mortality among those with chronic kidney disease (CKD). We examined the practice patterns of phosphate binder use to lower serum phosphorus levels and their associations with mortality in the non-dialysisdependent CKD population. METHODS: We examined the factors associated with the use of calcium and non-calcium phosphate binders in those with stage 3 and 4 CKD (eGFR 15 - 59 mL/min/1.73 m2) using logistic regression models. The associations between phosphate binder use and mortality were studied using propensity based analysis. RESULTS: Out of 57,928 patients with eGFR 15 - 59 mL/min/1.73 m2, 13,325 (23%) patients had serum phosphorus levels measured. 945 patients were prescribed phosphate binders, with 238 (25%) of them prescribed non-calcium-based phosphate binders and the rest calcium-based phosphate binders. Higher BMI, higher serum phosphorus, and higher serum calcium were associated with higher odds of being prescribed a non-calcium-based binder. Phosphate binder use was not significantly associated with mortality in either the entire cohort or the matched cohort in the analysis limited to those who were treated for at least 6 months. In the matched cohort, those who were treated for 1 year with a phosphate binder had a non-significant lower mortality rate (hazard ratio (HR): 0.85, 95% CI 0.66, 1.10). CONCLUSIONS: Phosphate binder use for 6 months and 1 year was not associated with reduced mortality in those with stage 3 and stage 4 CKD.

Multidimensional health status of HIV-infected outpatients at a tertiary care center in north India.

BACKGROUND: Quality of life (QOL) scores inform researchers acquainted with such tools about patients' perception of various domains of their health. The scores provide a useful denominator for clinical trials, especially in chronic diseases with therapeutic side effects, such as HIV. However, in clinical settings, there is a felt need of description of problems commonly perceived by patients. AIM: This study describes the multidimensional health-related issues of HIV-positive patients. SETTINGS AND DESIGN: Cross-sectional design with convenient sampling was used to recruit 138 HIV-positive patients at the outpatient section of the Department of Medicine of a tertiary care hospital in north India. MATERIALS AND METHODS: A structured questionnaire was used to collect information about health-related problems. Identified problems were assessed using a Likert scale for severity. RESULTS: Out of the 20 assessed problems, the patients reported positive for an average of 12.01 +/- 3.78 problems. The most prevalent problems were those related to emotions (98.6%), lack of energy (96.4%), and health perception (92.0%). The most distressing problems were 'feeling that health was not good' (77.5%) and 'health was bad' (75.4%). The number of problems reported was significantly related to weight loss ( P = 0.006) and clinical category ( P = 0.023). A significant correlation was observed between weight loss and problems in social activities ( P P P P = 0.002). CONCLUSION: Many patients have significant problems in dimensions other than physical. A physician's awareness about these problems is important for a holistic patient management.
