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.

BACKGROUND: Dentists, through inappropriate antibiotic prescription, may contribute to the global problem of antibiotic resistance (AR).
OBJECTIVE: Understanding dentists\' antibiotic prescription patterns, source of knowledge, and the driving forces behind their prescription practices may be crucial for the effective implementation of the rational use of antibiotics (RUA) in dentistry.
METHODS: Active members of the Turkish Dental Association were invited to participate in an electronic survey comprising questions focusing on their role, knowledge and perceptions regarding RUA, the perceived barriers to adapting RUA in daily dental work, and the actual antibiotic prescription practices. The potential impact of age, gender, professional experience, and the mode of dental practice was also evaluated. Dentists\' prescription practices for periodontal disease/conditions were evaluated as well.
RESULTS: Based on 1,005 valid responses, there was consensus on the necessity of RUA (99.1%); however, its implementation was low. The main barriers were dentists\' own safety concerns (74.4%), strong patients\' demands (42.2%) and the fact that prescribing antibiotics became a professional habit (35.8%). Different educational background resulted in clear variances in everyday prescription practices.
CONCLUSIONS: The implementation of RUA was not sufficient and the perceived barriers had an impact on daily prescribing habits. Support for dental professionals through the efficient dissemination of evidencebased clinical guidelines and decision-making aids is likely to require additional help from professional organizations in order to actively combat AR.

BACKGROUND: Potentially inappropriate medications (PIMs) are common among older adults with cancer, but their association with overall survival (OS) among non-small cell lung cancer (NSCLC) patients remains unclear. This study aimed to investigate the association between the use of PIMs and OS in patients with NSCLC.
METHODS: In this cohort study, we included patients ≥ 65 years with newly diagnosed NSCLC from January 2014 to December 2020. Potentially inappropriate medication (PIM) is defined by the Beers criteria of 2019 at baseline and within six months following the initiation of systemic therapy. Multivariable Cox regression model was built to assess the association between PIMs and overall survival (OS).
RESULTS: We finally included 338 patients with a median follow-up for OS of 1777 days. The prevalence of patients receiving at least one PIM was 39.9% (135/338) and 61.2% (71/116) at baseline and after systemic therapy, respectively. The most important factor associated with PIM use was the number of prescribed medications (P < 0.001). Baseline PIM use and PIM after systemic therapy were significantly associated with inferior OS (476 days vs. 844 days, P = 0.044; and 633 days vs. 1600 days, P = 0.007; respectively). In multivariable analysis, both baseline PIM use and PIM after systemic therapy were independent predictors of poor prognosis (adjusted HR, 1.33; 95% CI, 1.01-1.75; P = 0.041; and adjusted HR, 1.86; 95% CI, 1.11-3.14; P = 0.020; respectively).
CONCLUSIONS: PIMs are prevalent among older patients with NSCLC and are independent predictors of NSCLC prognosis. There is an urgent need for clinicians to conduct medication reconciliation and appropriate deprescribing for this population, especially for patients with multiple PIMs.

BACKGROUND: Older adults with advanced chronic diseases and palliative care needs are more exposed to polypharmacy and use of potentially inappropriate medication, which generates a high risk of adverse events and impaired quality of life. The objective of this study was to describe the frequency of potentially inappropriate medication use among older adults with palliative care needs receiving home care services after hospital discharge.
METHODS: Observational cross-sectional study of pharmacy dispensing and electronic health records, of older adults in a home care system and with palliative care needs according to the screening with the NECPAL tool or the PROFUND and/or PALIAR indexes. Dispensed medications during 180 days after admission to home care were analyzed. Medications were classified as potentially inappropriate according to the LESS-CHRON criteria.
RESULTS: We included 176 patients, mean age 87.4 years, 67% were women; 73% were pluripathologic patients and 22% had one chronic progressive disease. Mortality at 6 months was 73%. Median frequency of dispensed medications per patient was 9.1 (IQR = 4-9.7). The frequency of potentially inappropriate medication dispensation among patients was 87%, mainly antihypertensives, benzodiazepines and antipsychotics.
CONCLUSIONS: This study observed that dispensation of potentially inappropriate medication among older adults with palliative care needs and home care services is very high. This emphasizes the need for effective patient-centered interventions to prevent inadequate prescription and stimulate de-prescription.
Introducción: Los adultos mayores con enfermedades crónicas avanzadas y necesidad de cuidados paliativos están más expuestos a la polifarmacia y a consumir medicación potencialmente inapropiada, la cual genera un alto riesgo de eventos adversos y alteración de la calidad de vida. El objetivo de este estudio fue describir la frecuencia de consumo de medicación potencialmente inapropiada de adultos mayores con necesidad de cuidados paliativos que ingresaron a cuidados domiciliarios luego de una hospitalización. Métodos: Estudio de corte transversal observacional de registros de dispensación e historias clínicas electrónicas, de adultos mayores en un sistema de cuidados domiciliarios y con necesidades de cuidados paliativos según el rastreo con la herramienta NECPAL, los índices PROFUND y/o PALIAR. Se analizó el consumo de fármacos durante los 180 días posteriores al ingreso a cuidados domiciliarios. Se clasificaron los fármacos como potencialmente inapropiados según criterios de LESS-CHRON. Resultados: Se incluyeron 176 pacientes, edad promedio 87.4 años, 67% mujeres; 78% eran pluripatológicos y 22% presentaban una enfermedad única crónica progresiva. La mortalidad a los 6 meses fue 73%. La mediana de consumo de fármacos por paciente fue 9.1 (RIC = 4-9.7). El 87% consumía medicación potencialmente inapropiada, principalmente antihipertensivos, benzodiacepinas y antipsicóticos. Conclusión: Este estudio observó que los adultos mayores, con necesidad de cuidados paliativos en cuidados domiciliarios, tienen un alto consumo de medicación potencialmente inapropiada. Esto refuerza la necesidad de implementar intervenciones efectivas centradas en el paciente, para prevenir la prescripción inadecuada y estimular la de-prescripción.

BACKGROUND: Polypharmacy is a global public health concern. This study aimed to determine the prevalence of polypharmacy and trends in the use of commonly used and potentially inappropriate medications among older Korean patients.
METHODS: Individuals aged ≥ 65 years who were prescribed any medication between 2014 and 2018 were selected from the Korean National Health Information Database. Joinpoint regression analyses were used to determine trends in the age-adjusted polypharmacy rates by age group. The prescription rates of the most commonly used medications and the most commonly used potentially inappropriate medications were analysed by year or age group for patients with polypharmacy using the chi-square and proportion difference tests.
RESULTS: This study included 1,849,968 patients, 661,206 (35.7%) of whom had polypharmacy. Age-adjusted polypharmacy rates increased significantly between 2014 and 2018 (P = 0.046). Among patients with polypharmacy, the most commonly prescribed medications were aspirin (100 mg), atorvastatin, metformin, glimepiride, and rosuvastatin. The most commonly prescribed and potentially inappropriate medications were alprazolam, diazepam, amitriptyline, zolpidem, and dimenhydrinate. There was a significant decrease in the prescription rates for each of these drugs in 2018 compared with 2014 among patients with polypharmacy (all P < 0.001), whereas there was a significant increase in alprazolam prescription among patients aged ≥ 85 years when analysed by age group (P < 0.001).
CONCLUSIONS: This study revealed an increasing prevalence of polypharmacy among older adults. Additionally, it highlighted that the utilisation of commonly prescribed potentially inappropriate medications, such as benzodiazepines and tricyclic antidepressants, has remained persistent, particularly among patients aged ≥ 85 years who practiced polypharmacy. These findings provide evidence-based guidance for the development of robust polypharmacy management strategies to ensure medication safety among older adults.

UNASSIGNED: Potentially inappropriate medication (PIM) exposes patients to an increased risk of adverse outcomes. Many lists of explicit criteria provide guidance on identifying PIM and recommend alternative prescribing, but the complexity of available lists limits their applicability and the amount of data available on PIM prescribing.
UNASSIGNED: To determine PIM prevalence and the most frequently prescribed PIMs according to 6 well-known PIM lists and to develop a best practice synthesis for clinicians.
UNASSIGNED: This cross-sectional study used anonymized electronic health record data of Swiss primary care patients aged 65 years or older with drug prescriptions from January 1, 2020, to December 31, 2021, extracted from a large primary care database in Switzerland, the FIRE project. Data analyses took place from October 2022 to September 2023.
UNASSIGNED: PIM prescription according to PIM criteria operationalized for use with FIRE data.
UNASSIGNED: The primary outcomes were PIM prevalence (percentage of patients with 1 or more PIMs) and PIM frequency (percentage of prescriptions identified as PIMs) according to the individual PIM lists and a combination of all 6 lists. The PIM lists used were the American 2019 Updated Beers criteria, the French list by Laroche et al, the Norwegian General Practice Norwegian (NORGEP) criteria, the German PRISCUS list, the Austrian list by Mann et al, and the EU(7) consensus list of 7 European countries.
UNASSIGNED: This study included 115 867 patients 65 years or older (mean [SD] age, 76.0 [7.9] years; 55.8% female) with 1 211 227 prescriptions. Among all patients, 86 715 (74.8%) were aged 70 years or older, and 60 670 (52.4%) were aged 75 years or older. PIM prevalence among patients 65 years or older was 31.5% (according to Beers 2019), 15.4% (Laroche), 16.1% (NORGEP), 12.7% (PRISCUS), 31.2% (Mann), 37.1% (EU[7]), and 52.3% (combined list). PIM prevalence increased with age according to every PIM list (eg, according to Beers 2019, from 31.5% at age 65 years or older to 37.4% for those 75 years or older, and when the lists were combined, PIM prevalence increased from 52.3% to 56.7% in those 2 age groups, respectively). PIM frequency was 10.3% (Beers 2019), 3.9% (Laroche), 4.3% (NORGEP), 2.4% (PRISCUS), 6.7% (Mann), 9.7% (EU[7]), and 19.3% (combined list). According to the combined list, the 5 most frequently prescribed PIMs were pantoprazole (9.3% of all PIMs prescribed), ibuprofen (6.9%), diclofenac (6.3%), zolpidem (4.5%), and lorazepam (3.7%). Almost two-thirds (63.5%) of all PIM prescriptions belonged to 5 drug classes: analgesics (26.9% of all PIMs prescribed), proton pump inhibitors (12.1%), benzodiazepines and benzodiazepine-like drugs (11.2%), antidepressants (7.0%), and neuroleptics (6.3%).
UNASSIGNED: In this cross-sectional study of adults aged 65 or older, PIM prevalence was high, varied considerably depending on the criteria applied, and increased consistently with age. However, only few drug classes accounted for the majority of all prescriptions that were PIM according to any of the 6 PIM lists, and by considering this manageable number of drug classes, clinicians could essentially comply with all 6 PIM lists. These results raise awareness of the most common PIMs and emphasize the need for careful consideration of their risks and benefits and targeted deprescribing.

Inappropriate antibiotic use contributes to antimicrobial resistance, a global public health threat. The non-specific manifestations of dengue, itself a growing public health threat, lead to avoidable empiric antibiotic prescription, particularly in children. In this national pooled population-based cross-sectional study, we evaluated child and physician characteristics associated with antibiotics prescription in confirmed dengue cases in Taiwan. Linking national health care insurance claims and reports of confirmed dengue cases from 2008 to 2015, there were 7086 children with confirmed dengue with 21 744 outpatient visits and 2520 inpatient admissions. We assessed the presence of antibiotic prescription in outpatient and inpatient settings separately a week before or after the confirmation date. Logistic regression models with generalized estimating equations were applied to identify patient, practitioner, and other factors associated with antibiotic prescription. A total of 29.4% of children <18 years old with dengue who did not have a concomitant bacterial infection were prescribed antibiotics during the 14-day assessment period. Antibiotics prescription was reduced from 13.5% to 6.3% and from 43.2% to 19.3% in outpatient and inpatient settings, respectively, after dengue was confirmed. Young children were more likely to receive antibiotics. Significant variations in antibiotic prescribing across physicians were observed only in outpatient settings: physicians ≥60 years old and physicians practicing at clinics and in non-urban facilities were more likely to prescribe antibiotics. Antibiotics were less likely to be prescribed during an exceptional 2-year epidemic than in other years. Antibiotic prescribing for dengue, an arboviral infection affecting half of the global population, was shown to occur in 29% of paediatric cases in Taiwan. That potentially avoidable antibiotic consumption could be reduced by improving antibiotic stewardship, informed by understanding the conditions under which antibiotics are prescribed and the availability of prevention strategies for viral diseases, including dengue. We identified a number of such factors in this national population-based study.

BACKGROUND: The management of inappropriate medication use in older patients suffering from multimorbidity and polymedication is a major healthcare challenge. In a primary care setting, a medication review is an effective tool through which a pharmacist can collaborate with a practitioner to detect inappropriate drug use.
OBJECTIVE: This project described the implementation of a systematic process for the management of potentially inappropriate medication use among Lebanese older adults. Its aim was to involve pharmacists in geriatric care and to suggest treatment optimization through the analysis of prescriptions using explicit and implicit criteria.
METHODS: This study evaluated the medications of patients over 65 years taking a minimum of five chronic medications a day in different regions of Lebanon. Descriptive statistics for all the included variables using mean and standard deviation (Mean (SD)) for continuous variables and frequency and percentage (n, (%)) for multinomial variables were then performed.
RESULTS: A total of 850 patients (50.7% women, 28.6% frail, 75.7 (8.01) mean age (SD)) were included in this study. The mean number of drugs per prescription was 7.10 (2.45). Roughly 88% of patients (n = 748) had at least one potentially inappropriate drug prescription: 66.4% and 64.4% of the patients had at least 1 drug with an unfavorable benefit-to-risk ratio according to Beers and EU(7)-PIM respectively. Nearly 50.4% of patients took at least one medication with no indication. The pharmacists recommended discontinuing medication for 76.5% of the cases of drug related problems. 26.6% of the overall proposed interventions were implemented.
CONCLUSIONS: The rate of potentially inappropriate drug prescribing (PIDP) (88%) was higher than the rates previously reported in Europe, US, and Canada. It was also higher than studies conducted in Lebanon where it varied from 22.4 to 80% depending on the explicit criteria used, the settings, and the medical conditions of the patients. We used both implicit and explicit criteria with five different lists to improve the detection of all types of inappropriate medication use since Lebanon obtains drugs from many different sources. Another potential source for variation is the lack of a standardized process for the assessment of outpatient medication use in the elderly.
CONCLUSIONS: The prevalence PIDP detected in the sample was higher than the percentages reported in previous literature. Systematic review of prescriptions has the capacity to identify and resolve pharmaceutical care issues thus improving geriatric care.

BACKGROUND: Proton Pump Inhibitors (PPI) are frequently prescribed. Long-term use is associated with side-effects and patients often lack a valid indication. Inappropriate PPI prescribing thus needs to be addressed. This review aims to scope 1) what determinants are studied as reasons for PPI prescribing, 2) what strategies are used for changing PPI (de)prescribing, and 3) whether important determinants are addressed in these interventions.
METHODS: We searched eight databases for papers on determinants of physician PPI prescribing. Studies were included if they were conducted in a Western country and focused on oral PPIs for an adult population. By following the Behaviour Change Wheel, we extracted information regarding PPI prescribing behavior, behavioral determinants and intervention strategies.
RESULTS: We included 74 papers. Most focused on the determinants knowledge and beliefs about consequences. The latter was consistently related to PPI prescribing. Results for knowledge were mixed. Most interventions used education or enablement (e.g., algorithms, quality check improvements, involvement of pharmacists) as strategies. Enablement consistently improved PPI prescribing, while results for education were mixed.
CONCLUSIONS: There is an overemphasis on reflective processes in studies on PPI prescribing. Future research should comprehensively identify behavioral determinants, focusing on reflective and impulsive processes, such that interventions can address the most important determinants.
