Factors Contributing to Negative Outcomes Associated with Medications and Drug-Related Problems in Kidney Replacement Therapy-A Hospital-Based Prospective Observational Study.

BACKGROUND: Negative outcomes associated with medications (NOM) and drug-related problems (DRP) significantly impact individuals with kidney replacement therapy (KRT) given the complexities of managing kidney disease and associated comorbidities. The present study aims to assess the frequency of NOMs/DRPs among KRT patients and identify contributing factors. METHODS: A cross-sectional study was conducted at Virgen de las Nieves University Hospital (Granada, Spain), involving 117 outpatient adults with KRT. Data were collected from February 2021 to July 2023 using electronic records, semi-structured interviews (Dáder Method), and discussions with nephrology specialists. NOMs/DRPs were identified following treatment guidelines. Binary logistic regression was used to determine associated factors (p-value < 0.05). RESULTS: Across 117 patients, 2436 NOMs and 3303 DRPs were identified, averaging 20.82 NOMs and 28.23 DRPs per patient. Prevalent NOMs included untreated conditions (58.95%), quantitative ineffectiveness (35.43%), and non-quantitative safety problems (5.13%). Dominant DRPs were undertreated conditions (37.63%), wrong dose/posology/length (33.00%), risk of adverse drug reactions (ADR) (16.14%), and non-adherence (6.87%). Patients with ADR, undertreated conditions, and anemia were associated with quantitative ineffectiveness. Risk of ADR and vitamin D deficiency/insufficiency correlated with non-quantitative safety problems. CONCLUSIONS: KRT patients exhibited a substantial prevalence of NOMs/DRPs. Further research is needed to deepen our understanding of these complexities for improved patient care.

Health-Related Quality of Life and Associated Factors in Patients Undergoing Kidney Replacement Therapies.

OBJECTIVE: Characterize the health-related quality of life among patients undergoing kidney replacement therapy and to explore associated factors. METHOD: A descriptive observational study was conducted using the Kidney Disease Quality of Life Short Form questionnaire to assess health-related quality of life. The Dader Method was employed to evaluate negative outcomes associated with medications. Face-to-face interviews and clinical records were utilized to collect sociodemographic and clinical data from patients undergoing kidney replacement therapy at the Nephrology Department of Virgen de las Nieves University Hospital (Granada, Spain). We explored the association between independent variables (clinical and demographic factors) and dependent variables (Mental Component Score and Physical Component Score) using the linear regression method. RESULTS: Ninety-one participants were included, 47 (48.35%) were females. The mean age was 62 years, 52 patients (57.14%) were on hemodialysis, 13 patients (14.29%) on peritoneal dialysis, and 26 patients (28.57%) on other forms of kidney replacement therapy. The study revealed a mean Physical Component Score of 40.89 and a Mental Component Score of 47.19. Additionally, 98.90% of the patients experienced negative outcomes associated with medications. Influential factors include age, comorbid conditions, the number of medications, and clinical parameters such as vitamin D and calcium levels. CONCLUSIONS: This study underscores significant findings in patients undergoing kidney replacement therapy, indicating low Mental Component Score and Physical Component Score, accompanied by negative outcomes associated with medications.

Medication Review with Follow-Up for End-Stage Renal Disease: Drug-Related Problems and Negative Outcomes Associated with Medication-A Systematic Review.

BACKGROUND: This article reviews the available scientific literature on drug-related problems and negative outcomes associated with medications identified by medication review with follow-up for end-stage renal disease and discussed with the physicians. METHODS: A systematic review was conducted of the scientific literature retrieved from the following databases: MEDLINE (via PubMed), Web of Science, SCOPUS, Cochrane Library: The Cochrane Central Register and Control Trials (CENTRAL) and Literatura Latinoamericana y del Caribe (LILACS), Medicina en Español (MEDES), and the SciELO bibliographic database (a collection of scientific journals). The following terms were used as descriptors and searched in free text: "end-stage renal disease", "medication review", "drug-related problems", and "negative outcomes associated with medication". The following limits were applied: "humans" and "adults (more than 18 years)". RESULTS: A total of 59 references were recovered and, after applying inclusion/exclusion criteria, 16 articles were selected. Of these selected articles, 15 provided information on drug-related problems and only 1 on negative outcomes associated with medications. CONCLUSIONS: It can be concluded that drug-related problems and negative outcomes associated with medications affect patients with end-stage renal disease, mainly those receiving renal replacement therapy. More evidence is needed, especially on negative outcomes associated with medication.
