Falls in hospitalized older adults and the use of fall risk-increasing drugs and anticholinergic medications in Colombia: a case‒control study.

Introduction: In-hospital falls are multicausal in older hospitalized patients. Drugs with anticholinergic load and psychotropic effects can increase the risk of falling. Objective: This study aimed to determine the associations between fall risk-increasing drugs (FRIDs) and the anticholinergic risk score (ARS) with falls in hospitalized older hospitalized patients. Methods: This was a case‒control study of patients ≥65 years of age of either sex treated in four clinics in Colombia between 2018 and 2020. Each patient who suffered a fall during hospitalization was matched with four hospitalized patients who did not. Sociodemographic, clinical, and pharmacologic variables and the use of the ARS and FRIDs were evaluated. The risk associated with FRIDs was estimated using conditional logistic regression. Results: There were 250 patients and 1,000 controls (ratio of 1:4), with a mean age of 77.4 ± 7.4 years and a predominance of men (n = 800, 64.0%). The majority of falls occurred during hospitalization (n = 192 patients, 76.8%). Polypharmacy, calcium channel blockers, antiepileptics, antipsychotics, sodium-glucose cotransporter type 2 inhibitors, and nonsteroidal anti-inflammatory drugs were associated with falls during hospitalization. With an ARS score of 3, the probability of falling during the hospital stay increased (aOR: 2.34; 95% CI: 1.64-3.32). Conclusion: There is an association between suffering a fall and the use of drugs with anticholinergic load or FRIDs in hospitalized adults more than 65 years of age in Colombia.

Falls in older adults hospitalized in tertiary centers in Colombia. Clinical description and complications.

OBJECTIVE: The incidence of falls in elderly patients in the hospital environment is three times higher than that in the community. The aim was to determine the characteristics of patients who suffered in-hospital falls and their complications. METHODS: This was a cross-sectional study with patients older than 64 years of age, admitted between 2018 and 2020 to four clinics in Colombia who presented a fall during their stay. Clinical data, reasons for the fall, complications and use of drugs with a known risk for causing falls and with an anticholinergic load were reviewed. RESULTS: A total of 249 patients were included. The mean age was 77.5 ± 7.4 years, and there was a predominance of males (63.9%). The patients were hospitalized mainly for community-acquired pneumonia (12.4%) and heart failure (10.4%). Falls occurred most frequently in hospitalization wards (77.1%) and emergency departments (20.9%). Falls were related to standing alone (34.4%) and on the way to the bathroom (28.9%), with 40.6% (n = 102) of falls resulting in trauma, especially to the head (27.7%); the incidence of fractures was low (3.2%). Ninety-two percent of patients had polypharmacy (≥5 drugs), 88.0% received psychotropic drugs, and 37.3% received drugs with an anticholinergic load ≥3 points. CONCLUSIONS: Hospitalized adults over 65 years of age suffered falls, mainly in hospitalization wards and emergency departments, especially during the process of solitary ambulation. Most had received psychotropic drugs and medications with a high anticholinergic load. These results suggest that it is necessary to improve risk prevention strategies for falls in this population.

Women's health in focus: Real-world data on valproate prescriptions during pregnancy - a cohort study in Catalonia (Spain).

OBJECTIVES: To characterise the exposure to valproate within a cohort of pregnant women using electronic health records (EHRs) from Catalonia (System for the Development of Research in Primary Care, SIDIAP). DESIGN: Drug-utilisation cohort study covering the period from January 2011 to June 2020. The study included pregnancy episodes of women from Catalonia identified by the algorithm. SETTING: Data were sourced from SIDIAP, a comprehensive EHR repository that includes information from various data sources: recorded prescriptions (both hospital and primary care), diagnoses and sociodemographic characteristics identified by primary care physicians, and sexual and reproductive health data from ASSIR (used by gynaecologists and midwives). PARTICIPANTS: Women aged 12-50 with at least one pregnancy episode occurred during January 2011-June 2020 and at least a prescription of valproate during pregnancy. PRIMARY AND SECONDARY OUTCOMES: Primary outcomes included valproate exposure, measured through prevalence and cumulative incidence in pregnancy episodes and by trimester. The impact of regulatory measures (risk mitigation measures, RMMs) was assessed, and prescriptions over time were analysed using interrupted time series analysis. Secondary outcomes included health issues, pregnancy outcomes, smoking habits and socioeconomic characteristics. RESULTS: A total of 99 605 pregnancies were identified, with at least 3.03‰ (95% CI 2.69‰ to 3.39‰) exposed to valproate at some point (302 pregnancies, 276 women). The median pregnancy duration was 38.30 weeks (IQR 12.6-40.1), and the median age at pregnancy was 32.37 years (IQR 27.20-36.56). Epilepsy was the most frequent health issue. The prevalence and cumulative incidence of valproate prescriptions decreased during pregnancy and increased postpregnancy. The RMMs implemented in 2014 led to a reduction in monthly valproate prescriptions during pregnancy in this cohort. CONCLUSIONS: The study highlights the decline in valproate prescriptions during pregnancy due to RMMs and underscores the need for standardised methodologies in future studies to ensure the safety of pregnant patients and optimise scientific evidence.

Efficacy and safety of opioid therapy guided by pharmacogenetics: a systematic review.

Aim: To perform a systematic review to determine the efficacy/safety of PGx-guided opioid therapy for chronic/postoperative pain. Materials & methods: We searched PubMed and other specialized databases. Articles were considered if they compared the efficacy/safety of PGx-guided opioid therapy versus usual care. The risk of bias assessment was performed using Cochrane tools. Results: A total of 3794 records were retrieved. Only five were included for data extraction. A lower requirement of analgesics during postoperative in the PGx-guided intervention arm was reported in two studies. Also, two studies reported significant pain improvement in favor of the PGx-guided therapy when analyzing the subgroup of patients with a high-risk CYP2D6 phenotype. Conclusion: Despite the findings described, information on the efficacy/safety of this intervention is scarce.
