Ergocalciferol Versus Cholecalciferol in Non-Dialysis Dependent Chronic Kidney Disease Patients: A Small Retrospective Cohort Study.

PURPOSE: The purpose of this retrospective cohort study was to measure the difference between cholecalciferol and ergocalciferol in their ability to effect vitamin D, parathyroid hormone (PTH), calcium, and phosphorous serum concentrations in patients with stage 3 or 4 chronic kidney disease. METHODS: This was a retrospective cohort study conducted within a single-center ambulatory nephrology clinic. Patients eligible for the study were identified through medical records displaying each patient's initiation on either ergocalciferol or cholecalciferol from 2013 to 2016. Patients' baseline vitamin D, PTH, calcium, and phosphorous serum concentrations were taken prior to treatment initiation, and patients were reassessed with a second measurement within 12 months of therapy. RESULTS: Out of 149 eligible patients, 110 were excluded. There were 33 patients included on cholecalciferol and 6 patients on ergocalciferol. A significant difference was observed in the percent change of phosphorous serum concentrations from baseline following drug administration (p=0.03). The mean changes from baseline to final serum phosphorous concentrations (mg/dL) were 0.12 and -0.3 for cholecalciferol and ergocalciferol, respectively. There was no significant difference in vitamin D (14.9, 15.1, p=0.97), PTH (5.6, 2.3, p=0.72), or calcium (0.05, -0.17, p=0.08) serum concentrations between cholecalciferol and ergocalciferol, respectively. There was a statistically significant increase in the mean change in serum phosphorous concentrations within the cholecalciferol group compared to the ergocalciferol group. CONCLUSION: In this small pilot study, cholecalciferol treatment appeared to increase serum phosphorous concentrations compared to ergocalciferol. These observations may warrant further large-scale studies that are appropriately powered to validate such findings.

Using Data to Strengthen Ambulatory Oncology Nursing Practice.

BACKGROUND: Efforts to measure quality of care do not capture the unique aspects of ambulatory oncology settings. To retain nurses, ensure a safe practice environment, and encourage behaviors that support high-quality care, there is a need to identify factors associated with job satisfaction and turnover with measures that reflect the ambulatory setting. OBJECTIVE: The objective of this study was to examine the patterns and correlates of the work environment for nurses and nurse practitioners working in a National Cancer Institute-designated Comprehensive Cancer Center. METHODS: Web-based questionnaires were disseminated to employees with a registered nurse license in ambulatory settings and related support services and included 3 affiliated satellite locations. Participants completed the Practice Environment Scale of the Nursing Work Index, revised for ambulatory oncology settings, the Safety Organizing Scale, and items to assess job satisfaction, perceived quality of care, and intention to leave their current position. Logistic and linear regression models were used to examine factors associated with these outcomes. RESULTS: From 403 individuals, 319 (79.2%) participated. The majority of respondents endorsed excellent quality of care (57.7%), job satisfaction (69.3%), and intention to stay in current position (77.4%). Endorsement of favorable collegial nurse-physician relationships was significantly associated with all 3 outcomes and increased performance of safety organizing behaviors. Nurses reported variations in practice environments and safety organizing behaviors across units. CONCLUSIONS: Work environment assessments are useful to retain experienced nurses and support the delivery of high-quality patient care. IMPLICATIONS FOR PRACTICE: Routine assessment of the work environment for registered nurses and advanced practice nurses is feasible and informative.
