Antibiotic Prescribing Behavior of Physicians in Outpatient Departments in Hospitals in Northwest Ethiopia: Structural Equation Modeling Approach.

Antibiotic resistance, fueled by irrational prescribing, is a global threat associated with health, social, and economic consequences. Understanding antibiotic prescribing behavior and associated factors is important to promote good prescribing practice. This study aimed to determine the factors affecting antibiotic prescribing behaviors of physicians based on the theory of planned behavior in hospitals in northwest Ethiopia in 2022. A cross-sectional study was conducted from September 2022 to October 2022. A total of 185 health professionals were included, and a self-administered questionnaire was used to collect data. A structural equation model based on the modified theory of planned behavior was used to determine factors affecting antibiotic prescribing behavior. The percentages of physicians' estimated prescriptions for patients with upper respiratory tract infections (URTIs) and during weekly outpatient visits were used to predict antibiotic prescribing behavior and finally linked with behavioral constructs. A P value <.05 was considered significant. Physicians estimated that they prescribed antibiotics for 54.8% (9896/18,049) of weekly outpatient encounters, and 178 (96.2%) of the 185 physicians estimated they prescribed antibiotics for patients who presented with symptoms of a URTI. Physicians aged ≤30 years were less likely to prescribe antibiotics (48/100, 48%) for patients who presented with a URTI than physicians older than 30 years (51/100, 51%; P=.004), and general practitioners were less likely to prescribe antibiotics (47/100, 47%) for patients who presented with a URTI than residents (51/100, 51%; P=.03). Similarly, during outpatient visits, physicians ≤30 years old were less likely to prescribe antibiotics (54/100, 54%) than physicians older than 30 years (57/100, 57%; P<.001), male physicians were less likely to prescribe antibiotics (53/100, 53%) than female physicians (64/100, 64%; P=.03), and general practitioners were less likely to prescribe antibiotics (53/100, 53%) than residents (57/100, 57%; P=.02). Physicians with good knowledge were less affected by perceived social pressure (mean 4.4, SD 0.6) than those with poor knowledge (mean 4.0, SD 0.9; P<.001) and felt it was easy to make rational decisions (mean 4.1, SD 1.1) compared with those with poor knowledge (mean 3.8, SD 1; P<.001). However, intentions to reduce and prescribe antibiotics were not affected by attitudes, subjective norms, or perceived behavioral control, and perceived antibiotic prescribing behavior was not related to intentions to reduce or prescribe antibiotics. Antibiotic prescribing behavior was not under the volitional control of physicians. This calls for a systematic approach to change antibiotic prescribing practices in hospital.

Optimizing Inventory Management: Data-Driven Insights from K-Means Clustering Analysis of Prescription Patterns

Purpose: The goal is to improve how inventory is managed in healthcare by using K-Means clustering to analyze prescription trends. This approach helps ensure better stock availability, streamlines operations, and ultimately increases sales opportunities. Methods: This research applied the K-Means clustering algorithm to analyze a comprehensive dataset of prescription behaviors from XYZ Clinic. By grouping similar prescriptions into clusters, this method highlighted patterns within the data. These insights led to the identification of unique prescription categories, enabling the creation of tailored recommendations for improving inventory management. Result: The analysis showed that Cluster 1 should be prioritized for inventory management due to its high sales potential and consistent prescription patterns. It is recommended to increase stock for the medications in Cluster 1 to improve inventory turnover and streamline clinical operations. These findings underscore the value of K-Means clustering in healthcare, especially for enhancing inventory management and operational efficiency. Novelty: This research presents a novel application of K-Means clustering in healthcare, focusing on prescription patterns and inventory management. While previous studies have primarily used K-Means clustering for areas such as risk assessment and logistics, this study provides valuable data-driven insights to improve inventory management strategies in healthcare. The results highlight how clustering methods can support better decision-making and resource allocation, ultimately leading to greater operational efficiency and improved patient care.

Prescriber Phenotypes: Variability in Topical Rosacea Treatment Patterns among United States Dermatologists

Background/Objectives: Aggregate prescribing behavior for inflammatory lesions of rosacea has been described, but individual physician behavior has not been characterized. This study aims to assess the modern state of topical rosacea drug selection by analyzing prescribing patterns among individual dermatologists. Methods: We assessed utilization patterns of four topical papulopustular rosacea agents in 2021 Medicare Part-D data. K-means cluster analysis identified prescriber phenotypes based on the proportion of claims for each drug by physician. Results: Cluster analysis identified four prescriber phenotypes for topical rosacea agents, with the majority favoring metronidazole. In each of the other clusters, metronidazole was co-prescribed alongside the primary agent. Significant predictors of phenotype included patient ages, patient risk scores, and a group practice setting. Conclusions: The study reveals nonuniform prescribing patterns for topical papulopustular rosacea treatments among U.S. dermatologists. While aggregate data indicate diverse drug utilization, cluster analysis suggests that individual prescribers tend to use a limited selection of agents.

Under-Prescription of Drugs in the Elderly Population of Western Romania: An Analysis Based on STOPP/START Version 2 Criteria.

Background/Objectives: Numerous European countries, including Romania, are facing the concern of rapid ageing of their populations. Moreover, Romania's life expectancy ranks among the lowest in the European Union. In light of this, it is imperative that the assessment of medication-related harm be given national priority in order to secure and enhance pharmacotherapy and the medical act. In this study, we sought to describe and evaluate the under-prescribing practices among the Romanian elderly population. Methods: We conducted a cross-sectional study in urban areas of two counties in Western Romania (Timis and Arad) from November 2017 to February 2019. We collected chronic electronic prescriptions issued for elderly patients (>65 years old) with chronic conditions. The medication was prescribed by generalist or specialist physicians for periods ranging between 30 and 90 days. To assess inappropriate prescribing behaviours, a multidisciplinary team of specialists applied the Screening Tool of Older Persons' Prescriptions/Screening Tool to Alert to Right Treatment (STOPP/START) v.2 criteria to the collected prescriptions. Results: Within the 1498 prescriptions included in the study, 57% were issued to females, the mean age was 74.1 ± 6.95, and the average number of medicines per prescription was 4.7 ± 1.51. The STOPP criteria most commonly identified were the (1) long treatment duration (23.6%) and (2) prescription of neuroleptics (14.6%) or zopiclone (14.0%) as medications that increase the risk of falls. According to START criteria, the following medicines were under-prescribed: (1) statins (47.4%), (2) beta-blockers (24.5%), (3) antiresorptive therapy (10.0%), and (4) β2-agonists and muscarinic antagonists for chronic obstructive pulmonary disease (COPD) (4.5%). Within our study group, the prevalence of potentially inappropriate medications was 18.58%, whereas the prevalence of potential prescribing omissions was 49.2%. Conclusions: To decrease medication-related harm and morbid-mortality, and to increase the quality of life for elderly people in Romania, immediate actions are needed from national authorities. These actions include reinforcing primary care services, providing periodic training for physicians, implementing medication review services by pharmacists, and utilising electronic health records at their full capacity.

Scope of practice and opioid prescribing behavior of nurse practitioners serving Medicare beneficiaries.

Policymakers aiming to increase access to health care while simultaneously keeping costs low and quality high are considering expanding the practice authority and prescriptive authority of nurse practitioners in order to address primary care shortages. While we know this increases access, some researchers argue that the expansion of job autonomy of nurse practitioners can compromise the quality and safety of rendered medical services. This paper investigates quality and safety outcomes in prescribing behaviors of nurse practitioners who have prescribed opioids for Medicare Part D beneficiaries using a unique source of policy variation, nurse practitioners with the ability to prescribe medication who move to either states with or without physician supervision. We find that scope of practice expansions do not compromise quality and safety in terms of potential abuse or misuse of prescriptive authority.

5040 Leveraging Continuous Glucose Monitoring Data as an Additional Source for Glucagon Prescription Behavior

Abstract Disclosure: J. Ambalavanan: None. J. Rusticelli: None. D. Isaacs: Consulting Fee; Self; Medtronic Diabetes, Lilly USA, LLC, Novo Nordisk, Insulet Corporation, Abbott Laboratories, Dexcom. H. Xiao: None. J. Bena: None. Z. Jin: None. C. Babiuch: None. M. Lansang: Consulting Fee; Self; Glooko. Research Investigator; Self; Abbott Laboratories, Dexcom, Xeris. Background: Hypoglycemia is a major source of anxiety in, and can be life-threatening for, patients with diabetes (DM). Even though the American Diabetes Association (ADA) recommends glucagon be made available to all individuals taking insulin or at high risk for hypoglycemia (level E evidence), few patients have access to this life-saving medication. Given the rapid adoption of continuous glucose monitoring (CGM) in the management of DM, we aimed to 1) evaluate glucagon prescription by identifying patients with hypoglycemia on CGM reports, and 2) deliver an educational letter to the providers. Methods: Our study had a retrospective chart review and a quality improvement (QI) component. From Mar-Oct 2023, we identified adult patients in the Cleveland Clinic Ohio health system with type 1 or type 2 DM on insulin (including insulin pumps), sulfonylurea, or meglitinide, and hypoglycemia defined as time below range (TBR) ≥4% on CGM reports. We evaluated the percentages of pre-existing and incident glucagon prescription among those patients. For the QI component, we contacted providers individually via letter if the patients did not have a glucagon prescription and shared with them the ADA Standards of Care on hypoglycemia along with information about various forms of glucagon. Whether to prescribe glucagon was left to the clinical judgement of the providers. Information was collected 4 weeks later to see whether there was any change in the prescription practice. Results: Patients numbered 1543, with170 patients having TBR ≥4%. Among patients with hypoglycemia, 37% had pre-existing prescription and 14% incident glucagon prescription, compared with patients without hypoglycemia (p&amp;lt;0.001). Significant (p&amp;lt;0.001) risk factors for hypoglycemia included type 1 DM, insulin-only therapy, use of conventional insulin pumps, and lower A1c. Among patients with TBR ≥4%, 66 (39%) had level 1 hypoglycemia (54 to &amp;lt;70 mg/dl), 88 (52%) had level 2, and 16 (9%) had level 3 (hospitalization or ER admission for hypoglycemia). Pre-existing or incident glucagon prescription was seen in 28% without hypoglycemia, 38% with level 1 hypoglycemia, 49% with level 2, and 63% with level 3 (p&amp;lt;0.001 level 1 vs level 3; level 2 vs no hypoglycemia; level 3 vs no hypoglycemia). Among 70 patients whose providers received education letters, 27 (39%) prescribed glucagon after education. Glucagon emergency kit, glucagon autoinjector, and inhaled glucagon were the top prescription choices. A greater proportion of advanced practice providers responded to our education than physicians (p=0.021). Conclusion: Glucagon prescription remains suboptimal though better than in other studies even among patients with documented hypoglycemia on CGM reports. Effective provider education and communication can increase glucagon prescription. Provider and patient factors should be studied next to determine steps for further improvement.

Psychiatrists effect on positive symptom severity and daily functioning during pharmacotherapy for first-episode psychosis patients

Clinical outcomes after a first-episode of psychosis (FEP) are heterogeneous. Many patient-related factors such as gender and comorbidity have been studied to predict symptomatic outcomes. However, psychiatrist-related factors such as prescription behaviour and gender have received little attention. We assessed the relationship between patients’ psychiatrists, psychosis severity and daily functioning in 201 patients remitted from an FEP for a duration of one year, treated by 18 different psychiatrists. We controlled for baseline severity, dose and type of antipsychotic medication, frequency of visits, and patients’ education. Symptom severity, daily functioning, and antipsychotic drug use were assessed at baseline and at 3, 6, and, 12 months follow-up. We found that psychiatrists accounted for 9.1% of the explained variance in patients’ symptom severity and 10.1% of the explained variance in daily functioning.These effects persisted even when controlling for factors such as baseline severity and the prescribed dose. The effect of prescribed dose on symptom severity and daily functioning differed between psychiatrists. Treatment centre, session frequency, and medication nonadherence were not related to symptom severity. Our results emphasize the importance of individual psychiatrist factors in symptomatic outcomes after an FEP. Further identification of psychiatrist-related factors such as the quality of therapeutic alliances and shared decision-making, may optimize psychiatrists’ training with the goal of improving patient outcomes.

Improving dihydropyrimidine dehydrogenase genotyping (DPYD) prior to initiation of fluoropyrimidine-based chemotherapy at a community-based hospital: A quality improvement initiative.

347 Background: Dihydropyrimidine dehydrogenase gene (DPYD) testing is crucial in preventing toxicities from fluoropyrimidine chemotherapy. Despite benefits and established guidelines, its adoption within healthcare organizations remains inconsistent and suboptimal. We implemented a quality improvement project to improve DPYD testing prior to fluoropyrimidine chemotherapy at a community-based hospital. We aimed to increase DPYD testing for patients receiving fluoropyrimidine-based chemotherapy from 65% to 95% between July 2023 to July 2024. Balancing measures included DPYD testing turnaround time. Methods: For baseline diagnostics, manual chart review was performed on 126 patients to identify frequency of DPYD testing, and turnaround time (TAT) between May 1, 2023 to August 4, 2023. Patients were excluded if they received fluoropyrimidine-based chemotherapy prior to May 1, 2023. A multidisciplinary team including medical oncology residents and staff, pharmacists, nurses, and clinical informatics specialists worked jointly to identify and address barriers to implementation. Barriers identified included lack of established workflows and awareness of the importance of testing. Diagnostic tools utilized included Ishikawa diagrams and process mapping. The team used Plan-Do-Study-Act (PDSA) cycles to address barriers. A p-chart was used to analyze the results. Results: The baseline DPYD testing rate was 65%. Barriers identified via multidisciplinary sessions included lack of established workflow, awareness and importance of testing. PDSA cycles included education sessions to breast medical oncologists and medical oncology nurses, and development of a best-practice advisory in the electronic medical record. The percentage of eligible patients receiving DPYD testing increased from 65% to 95.8% in the total population. For breast cancer patients, the rate increased from 16.7% to 100%. For gastrointestinal cancer patients, the rate increased from 56.1% to 94.2%. Sustainability was demonstrated two months post-intervention with TAT stable between 7-8 days. Conclusions: Through PDSA cycles, we improved the frequency of DPYD testing for patients receiving fluoropyrimidine chemotherapy from 65% to 95.8%. Future work will assess changes in chemotherapy prescribing behavior in the setting of variant DPYD results, and outcomes of patients with variant DPYD testing.

Time Trends, Regional Variation and Associations of Low-Allergy Formula Prescribing in England.

Cow's milk allergy (CMA) overdiagnosis appears to be increasing and is associated with excessive low-allergy formula prescription. We evaluated recent trends and regional variation in low-allergy formula prescribing for CMA in England, and assessed potential risk factors for higher prescribing rates. Data on national and regional prescribing of low-allergy formulas were extracted from England's electronic prescription database using R. Region-level factors were evaluated for potential associations with regional low-allergy formula prescription rates using multivariate linear regression. Analysis of national prescribing trends covered 2007-2023, analysis of regional variation and region-level factors examined 2017-2019, prior to a re-organisation of the regional healthcare structure in England. Low-allergy formula prescribing increased from 6.1 to 23.3 L per birth nationally, between 2007 and 2023. Regional prescribing rate varied from 0.8 to 47.6 L per birth in 2017-2019. We found significant associations between regional low-allergy formula prescribing rate and regional prescribing rates for milk feed thickeners Gaviscon Infant and Carobel Instant (β = 0.10, p < 0.01), and for other anti-reflux medications used in young children (β = 0.89 p < 0.01). Inconsistent associations were seen with prescribing junior adrenaline auto-injectors and oral antibiotics. A model including these four variables accounted for 37% of regional variation in low-allergy formula prescribing rate. Region-level socio-economic deprivation, CMA guideline recommendations and paediatric allergy service provision were not associated with low-allergy formula prescribing. Low-allergy formula prescribing in England is increasing, varies significantly by region and is consistently associated with prescribing rates for milk feed thickeners and other anti-reflux medication for young children. Community prescribing behaviours may be important determinants of CMA overdiagnosis.

Primary Healthcare Physicians' Insufficient Knowledge Is Associated with Antibiotic Overprescribing for Acute Upper Respiratory Tract Infections in China: A Cross-Sectional Study.

Overuse of antibiotics in healthcare remains prevalent and requires urgent attention in China, particularly in primary healthcare (PHC) facilities. This study aimed to describe the patterns of antibiotic prescriptions for acute upper respiratory tract infections (URTIs) in PHC facilities in China and to investigate how PHC physicians' knowledge influences their antibiotic prescribing behavior. A cross-sectional survey linking physician questionnaire responses and their prescription data was conducted in Shaanxi Province, China. The proportions of URTI visits that received at least one antibiotic, combined antibiotics, and broad-spectrum antibiotics were the main outcomes reflecting antibiotic prescribing behavior. Multivariate mixed-effects logistic regressions were applied to analyze the relationship between PHC physicians' knowledge about antibiotics and their antibiotic prescribing behavior. A total of 108 physicians filled out the questionnaires between February 2021 and July 2021, and a sample of 11,217 URTI visits attended by these physicians from 1 January 2020 to 31 December 2020 were included in the analysis. The overall mean score of our respondents on the knowledge questions was 5.2 (total score of 10). Over sixty percent (61.2%; IQR 50.2-72.1) of the URTI visits received antibiotics. The percentages of URTI visits prescribed with combined and broad-spectrum antibiotics were 7.8% (IQR 2.3-10.2) and 48.3% (IQR 36.7-58.7), respectively. Third-generation cephalosporins were the most frequently used antibiotics. Physicians with lower antibiotic knowledge scores were more inclined to prescribe antibiotics (p < 0.001), combined antibiotics (p = 0.001), and broad-spectrum antibiotics (p < 0.001). Physicians' insufficient knowledge was significantly associated with antibiotic overprescribing. Professional training targeting physicians' knowledge of antibiotics is urgently needed to improve the rational use of antibiotics in grassroots healthcare facilities in China.

Daily defined dose-costs have a stronger influence on antibacterial drug prescriptions in Germany than bacterial resistance: economic factors are more important than scientific evidence

AbstractPrevious research from our group revealed a strong association between daily defined dose (DDD)-costs and -prescriptions of antibacterial drugs in Germany (https://pubmed.ncbi.nlm.nih.gov/38842562/; https://pubmed.ncbi.nlm.nih.gov/39042156/). These data indicate that low costs are major driver of high prescription numbers. This study examines the relationship between bacterial resistance and DDD-prescriptions of antibacterial drugs using data from the Arzneiverordnungsreport (AVR) from 2008 to 2022 and the Antibiotic Resistance Surveillance (ARS) statistics provided by the Robert Koch Institute (RKI). We hypothesized that semi-rational or irrational prescribing behavior of antibacterial drugs is evident in Germany, i.e., prescriptions are driven to a greater extents by low DDD-costs than bacterial resistance. A bivariate correlation analysis was performed to test these models. Our data point to irrational prescribing behavior for amoxicillin, cefuroxime axetil, doxycycline, nitrofurantoin, ciprofloxacin, and clarithromycin. For amoxicillin clavulanic acid and sulfamethoxazole-trimethoprim, data point to semi-rational prescribing. For no antibacterial drug, a model pointing to rational drug prescribing was found. In conclusion, our study shows that DDD-costs exert a more significant influence on DDD-prescriptions than bacterial resistance, indicating that economic factors, rather than scientific evidence, primarily drive antibacterial drug prescriptions in outpatient settings in Germany. It will be important to conduct similar studies on the prescription of antibacterial drugs in other countries. It will also be important to study the relation between DDD-costs and -prescriptions for other drug classes and assess the scientific basis for these relations.

The Use of Nudge Strategies in Improving Physicians’ Prescribing Behavior: A Systematic Review and Meta-analysis

Background Nudges have been proposed as a method of influencing prescribing decisions. Purpose The purpose of this article is to 1) investigate associations between nudges’ characteristics and effectiveness, 2) assess the quality of the literature, 3) assess cost-effectiveness, and 4) create a synthesis with policy recommendations. Methods We searched health and social science databases. We included studies that targeted prescribing decisions, included a nudge, and used prescribing behavior as the outcome. We recorded study characteristics, effect size of the primary outcomes, and information on cost-effectiveness. We performed a meta-analysis on the standardized mean difference of the studies’ primary outcomes, tested for associations between effect size and key intervention characteristics, and created a funnel plot evaluating publication bias. Synthesis We identified 21 studies containing 25 nudges. In total, 62 of 85 (73%) outcomes showed a statistically significant effect. The average effect size was −0.22 standardized mean difference. No studies included heterogeneity analyses. We found no associations between effects and selected study characteristics. Study quality varied and correlated with study design. A total of 7 of 21 (33%) studies included an evaluation of costs. These studies suggested that the interventions were cost-effective but considered only direct effects. We found evidence of publication bias. Limitations Heterogeneity and few studies limit the possibilities of statistical inference about effectiveness. Conclusions Nudges may be effective at directing prescribing decisions, but effects are small and health effects and cost-effectiveness are unclear. Future nudge studies should contain a rationale for the chosen nudge, prioritize the use of high-quality study designs, and include evaluations of heterogeneity, cost-effectiveness, and health outcomes to inform decision makers. Moreover, preregistration of the protocol is warranted to limit publication bias. Highlights Nudging as a method to improve prescribing decisions has gained popularity during the past decade. We find that nudging can improve prescribing decisions, but effect sizes are mostly small, and the size of derived health outcomes is unclear. Most studies use feedback and error-stopping nudges to target excessive opioid or antibiotic prescribing, making heterogeneity analyses across nudge types difficult. Further research on the cost-effectiveness of nudges and generalizability is needed to guide decision makers considering nudging as a tool to guide prescribing decisions.

Septic tanks as a pathway for emerging contaminants to the aquatic environment–Need for alternative rural wastewater treatment?

Septic tanks (STs) as a decentralised approach to community wastewater treatment were investigated as a pathway for emerging contaminants (ECs) entering the aquatic environment. A broad range of ECs were examined in five community STs (population equivalents 217–475) and receiving rivers in Scotland over 12 months. All 68 studied ECs were detected at least once in ST influent or effluent at a broad concentration range from ng L−1 – μg L−1 which can surpass freshwater predicted no-effect concentrations. Pharmaceuticals with acute use, such as antibiotics and antifungals, had high monthly variability and concentrations can exceed those previously found in centralised wastewater treatment works. Differences between the STs demonstrate the impact of localised prescription and population behaviour on EC concentrations. The similarities in concentrations between influent and effluent, suggest limited or no removal of ECs in STs. Hence, dilution of the discharges is required to mitigate environmental risk. Although the contribution of ECs sorbed to suspended solids to the total EC concentration was generally small (<10%), higher contributions (>30%) were observed for fluoroquinolone antibiotics (ofloxacin and ciprofloxacin), antidepressants (fluoxetine), and antifungals (clotrimazole). A wide range of ECs were also detected in rivers upstream and downstream of the ST discharge points, and concentrations increased by up to 95% downstream. In general, risk quotients (RQs) in the rivers were low, indicating small risk for the environment. However, higher RQs (>1) were found for ibuprofen, diclofenac and ciprofloxacin in a few samples. Therefore, reducing their concentration by improving ST performance or through sustainable medicines use may be needed at low dilution locations to mitigate any risk.

Controlling Prescribing through "Preferred Drug" Targets-The Bavarian Experience.

The rising costs of drugs are putting health care systems under pressure. We report on the Bavarian Drug Agreement, which employs prescribing targets for preferred and generic drugs in ambulatory care. Under this agreement, providers are regularly profiled with individual feedback but also possible sanctions. We investigated the degree to which targets were being met (or not) and why failure occurred. We analysed prescribing data aggregated by practice for the quarter 1/2018. We chose eight specialisation groups and analysed their drug targets with a high prescribing volume, widely missed drug targets (<90%), and drugs preventing drug target achievement. Characterisation of drug targets and preventing drugs was undertaken. Drug targets with a high prescribing volume are mostly achieved, while highly missed drug targets mostly do not affect the main indication area of the specialisation groups considered. Generic drug targets seem to be more easily achieved than recommended drug targets. Paediatrics accounts for the largest number of missed drug targets. The Bavarian tool implemented uses the prescribing volume (DDD) and price components to evaluate the prescription behaviour of physicians. Well-established drugs with demonstrated effectiveness, safety, and lower costs are preferred. Nevertheless, me-too drugs, combination drugs, costly innovations with unclear value, and drugs with application methods of variable convenience challenge the drug prescribers and are reasons for missed drug targets.

Drivers of Variation in Opioid Prescribing after Common Surgical Procedures in a Large Multihospital Healthcare System.

Misuse of prescription opioids is a well-established contributor to the US opioid epidemic. The primary objective of this study was to identify which level of care delivery (ie patient, prescriber, or hospital) produced the most unwarranted variation in opioid prescribing after common surgical procedures. Electronic health record data from a large multihospital healthcare system were used in conjunction with random-effect models to examine variation in opioid prescribing practices after similar inpatient and outpatient surgical procedures between October 2019 and September 2021. Unwarranted variation was conceptualized as variation resulting from prescriber behavior unsupported by evidence. Covariates identified as drivers of warranted variation included characteristics known to influence pain levels or patient safety. All other model variables, including prescriber specialty and patient race, ethnicity, and insurance status were characterized as potential drivers of unwarranted variation. Among 25,188 procedures with an opioid prescription at hospital discharge, 53.5% exceeded guideline recommendations, corresponding to 13,228 patients receiving the equivalent of >140,000 excess 5 mg oxycodone tablets after surgical procedures. Prescribing variation was primarily driven by prescriber-level factors, with approximately half of the total variation in morphine milligram equivalents prescribed observed at the prescriber level and not explained by any measured variables. Unwarranted covariates associated with higher prescribed opioid quantity included non-Hispanic Black race, Medicare insurance, smoking history, later hospital discharge times, and prescription by a surgeon rather than a hospitalist or primary care provider. Given the large proportion of unexplained variation observed at the provider level, targeting prescribers through education and training may be an effective strategy for reducing postoperative opioid prescribing.

Nudging strategies to influence prescribers' behavior toward reducing opioid prescriptions: a systematic scoping review.

This systematic scoping review aimed to map the literature on the use of various nudging strategies to influence prescriber behavior toward reducing opioid prescriptions across diverse healthcare settings. A systematic database search was conducted using seven electronic databases. Only articles published in English were included. A total of 2234 articles were identified, 35 of which met the inclusion criteria. Two independent dimensions were used to describe nudging strategies according to user action and the timing of their implementation. Six nudging strategies were identified. The most common strategy was default choices, followed by increasing salience of information or incentives and providing feedback. Moreover, 32 studies used the electronic health record as an implementation method, and 29 reported significant results. Most of the effective interventions were multicomponent interventions (i.e., combining nudge strategies and non-nudge components). Most nudging strategies used a passive approach, such as defaulting prescriptions to generics and requiring no action from the prescriber. Although reported as effective, this approach often operates under the prescriber's radar. Future research should explore the ethical implications of nudging strategies.INPLASY registration number: 202420082.

Qualitative evaluation to Understand barriers and facilitators to prescribing angiotensin receptor-neprilysin inhibitors (ARNi) and sodium-glucose cotransporter inhibitors (SGLT2i) in patients with heart failure with reduced ejection fraction (HFrEF)

BackgroundDespite sodium-glucose cotransporter-2 inhibitors (SGLT2i) and angiotensin receptor/neprilysin inhibitors (ARNi) being cost-effective evidenced-based therapies for the management of Heart Failure with Reduced Ejection Fraction (HFrEF), research shows that less than 30% of patients with HFrEF are prescribed these agents. ObjectiveThis study aimed to understand clinician-perceived barriers and facilitators to prescribing ARNi and SGLT2i in patients with HFrEF. MethodsWe conducted virtual and in-person semi-structured interviews in a large integrated healthcare delivery system in the United States. Twenty cardiology clinicians managing patients with HFrEF were recruited using purposeful sampling to target providers across professions and practice sites. The interview guide was developed based on a literature review and insights from a practicing cardiologist. It inquired about perceived prescribing behaviors, focusing on factors affecting the use of ARNi and SGLT2i. We identified key themes using rapid qualitative analysis. ResultsTwenty clinicians were interviewed: 13 physicians, 5 advanced practitioners, and 2 clinic-based pharmacists. Eighteen interviews were analyzed; we excluded 2 as the clinicians interviewed did not meet the inclusion criteria. Three major themes were identified: 1) clinician-reported prescribing patterns don't always align with the American College of Cardiology/American Heart Association guidelines for the use of SGLT2i and ARNi due to clinical inertia, lack of familiarity, knowledge, and comfort with use, and concerns over polypharmacy or adverse events, 2) clinician-perceived and actual out-of-pocket cost reduced prescribing of ARNi or SGLT2i to patients, exacerbated by a lack of visibility into patients' prescription coverage, denials of coverage by insurance, and navigating prior authorization related workflows, and 3) incorporation of a clinic-based pharmacist increased the prescribing of these medications. ConclusionIncreasing cost transparency, implementing interventions to overcome clinical inertia and cost hurdles, and increasing clinic-based pharmacist support may improve evidenced-based prescribing in patients with HFrEF, especially for comparatively novel classes such as ARNi and SGLT2i.

Insights into Probiotic Prescription among Gastroenterologists and Other Healthcare Professionals: Evidence from an Italian Survey.

Background: Probiotics, which are live microorganisms that provide health benefits, have been extensively studied for their various clinical applications. However, despite their potential, high-quality data supporting their use in several gastrointestinal diseases are often lacking, and prescription behaviors can widely differ. This study aimed to assess different behaviors in probiotics knowledge and prescriptions among Italian gastroenterologists and healthcare professionals (HPs). Methods: A web-based electronic survey was distributed to all participants at the National Meeting of the Italian Young Gastroenterologist and Endoscopist Association (AGGEI) held in 2023. The survey investigated probiotic prescription practices for several gastrointestinal conditions, such as acute diarrhea, irritable bowel syndrome, inflammatory bowel disease, and diverticular disease. Results: Among 200 participants, 142 completed the survey, of whom 59 were gastroenterologists and 83 were HPs (surgeons, nutrition biologists, and other physicians). Significant differences were observed in the prescription of probiotics for the treatment of acute diarrhea and H. pylori. Both groups prescribed probiotics in monthly cycles for patients with IBS, although the majority prescribed multistrain formulations. Gastroenterologists were more likely to prescribe cyclic courses for IBS, while HPs tended to continue therapy by changing the probiotic strain in case of inefficacy. For ulcerative colitis, gastroenterologists prescribed probiotics more but for shorter durations. In Crohn's disease, gastroenterologists prescribed probiotics less and were less likely to prescribe multistrain formulations. Regarding SUDD, gastroenterologists tended to prescribe probiotics less frequently, although without a significant difference, with similar rates of preference for multistrain formulations. Conclusions: This survey highlights heterogeneous behaviors in probiotic prescription between gastroenterologists and HPs, with gastroenterologists more aligned with guidelines and available scientific evidence. Hence, enhancing probiotic education among healthcare professionals and gastroenterologists is crucial. Further studies are needed to better understand probiotics' role in gastrointestinal disorders through large-scale randomized controlled trials.

Factors affecting the essential medicine prescribing behavior among general practitioners in Beijing, China: a cross-sectional study with structural equation model

BackgroundThe aim of this study is to explore the influence of GPs’information, motivation and behavior skills on EM prescribing behavior in urban and suburban districts.MethodA cross-sectional study was conducted from June to November 2022 cross 3 urban districts and 4 suburban districts in Beijing. The structural equation model was used to analyze the factors influencing the essential medicine prescription behavior among general practitioners in urban and suburban districts.ResultsA total of 511 valid questionnaires were collected. There was a statistically significant difference in mean scores for personal motivation and behavioral skills between urban GPs and suburban GPs. For urban GPs, the path analysis revealed that the social motivation had a direct effect on the essential medicine prescribing behavior (β = 0.225, p < 0.05). In contrast, for suburban GPs, both social motivation and personal motivation had a direct effect on the essential medicine prescribing behavior, respectively (β = 0.175, p < 0.05; β = 0.193, p < 0.01).ConclusionSocial motivation of urban GPs were positively and significantly associated with essential medicine prescribing behavior. Social motivation and personal motivation of suburban GPs were positively and significantly associated with essential medicine prescribing behavior. Therefore, various corresponding policies and measures should be developed to promote the National Essential Medicines Policy in China.

A Real-world Study Evaluating the Clinical Factors Associated with the Initial SGLT2 Inhibitor Prescription

Abstract: The American Diabetes Association (ADA) guidelines prioritize Sodicum-glucose transporter-2-inhibitors (SGLT2i) given cardio-renal and glycemic benefits. This study was conducted to observe clinical factors associated with initial SGLT2i prescription in type 2 diabetes patients eligible for SGLT2i by the ADA. Methods. A retrospective case-control study was performed in a safety-net clinic and consisted of the initial SGLT2i prescriptions group and the group without. The data from the electronic medical records between July 2021 and December 2022 were analyzed in the regressional models. Results. There was a significant association between A1c ≥8% (OR 3.7, p=.01), heart failure (OR 19.3, p&lt;.0001), a history of hypotension (OR 11.9, p=.01), and sulfonylureas (OR 6.5, p=.003) with the SGLT2i prescription. Conclusion. Patients with high A1c levels, heart failure, a history of hypotension, and sulfonylureas were more likely than their counterparts to receive SGLT2i prescriptions. Future research should investigate adherence and provider prescribing behaviors related to SGLT2i to further assess optimal drug use.
