A behavioral intervention to promote use of multimodal pain medication for hospitalized patients: a randomized controlled trial.
Administration of nonsteroidal anti-inflammatory drugs (NSAIDs) has become a foundational strategy to decrease the use of opioids, but data is lacking to describe recommending utilization when admitting patients using electronic health record systems. The purpose of this study was to assess an electronic health record system to increase ordering of NSAIDs for hospitalized adults. The researchers conducted a cluster randomized controlled trial of clinicians admitting adult patients to a health system over a period of 9-months. Clinicians in the intervention arm were required to actively order or decline NSAIDs; the control arm was provided the same order but without a required response. A total of 20,085 hospitalizations were included. The study found that among the hospitalizations, 52% were admitted by a clinician randomized to the intervention arm. NSAIDs were ordered in 22% of the interventions and 22% of the control admissions. There were no statistically significant differences in NSAID administration, pain scores, or opioid prescribing. There were no differences in clinical harms, with average pain scores of 3.36 in the control group and 3.39 in the intervention group, on a scale of 0-5.

Best Practice Alerts Informed by Inpatient Opioid Intake to Reduce Opioid Prescribing after Surgery (PRIOR): a cluster randomized multiple crossover trial.
This study tested the hypothesis that a decision-support tool embedded in electronic health records (EHRs) leads clinicians to prescribe fewer opioids at discharge after inpatient surgery. Over 21,000 surgical inpatient discharges in a cluster randomized multiple crossover trial in four Colorado hospitals were included. The results indicated that within the context of vigorous opioid education and awareness efforts a decision-support tool incorporated into EHRs did not reduce discharge opioid prescribing for postoperative patients. The authors concluded that opioid prescribing alerts might be valuable in other contexts.

Internal and environmental predictors of physician practice use of screening and medications for opioid use disorders.
This study examined the extent of screening for opioid use and availability of medications for opioid use disorder (MOUD) in a national cross-section of multi-physician primary care and multispecialty practices. The authors found that a total of 26.2% of practices offered MOUD, while 69.4% of practices screened for opioid use. Offering of MOUD in a practice was associated with having advanced HIT functionality, while access to on-site behavioral clinicians was positively associated with offering MOUD in adjusted models.

Is exposure to pharmaceutical direct-to-consumer advertising for heart disease and diabetes associated with physical activity and dietary behavior?
This study examined associations between estimated exposure to direct consumer-to-advertising (DTCA) for drugs focused on heart disease/cholesterol and diabetes and self-reported exercise and consumption of a variety of unhealthy foods (candy, sugary drinks, alcohol, and fast food). The authors estimated exposure to DTCA by combining data from Kantar Media Intelligence (Kantar) on televised pharmaceutical DTCA airings in the U.S. from January 2003 to August 2016 (n = 7,696,851 airings) with thirteen years of data from the Simmons National Consumer Survey (Simmons), a mailed survey on television viewing patterns. They estimated associations between exposure to advertising (both overall and for advertisements with specific content) and self-reported physical activity and dietary behavior using Simmons data from January 2004 to December 2016 (n = 288,483 respondents from n = 157,621 unique households in the U.S.). They found that higher estimated exposure to DTCA for heart disease and diabetes drugs were not consistently associated with meaningful differences in the frequency of engaging in regular physical activity. However, greater estimated exposure to DTCA for both diseases were linked to small but consistently higher volume of consumption of candy, sugar-sweetened beverages, alcohol, and fast food.

What works in medication reconciliation: an on-treatment and site analysis of the MARQUIS2 study.
The objective of this study was to assess the association of patient exposure to system-level intervention and receipt based on the results of the second Multicenter Medication Reconciliation Quality Improvement Study, which demonstrated a marked reduction in medication discrepancies per patient. Researchers conducted an on-treatment analysis of system-level interventions at 17 North American hospitals. The patient-level interventions most associated with discrepancy reductions were receipt of a best-possible medication history of admitted patients in the ED and admission and discharge medication reconciliation by a trained clinician. System-level interventions were also associated with a minor reduction in discrepancies for the average patient. The researchers concluded that these findings might be used to help hospitals and health systems prioritize interventions to improve medication safety during care transitions.

Prevalence and appropriateness of in-person versus not-in-person ambulatory antibiotic prescribing in an integrated academic health system: a cohort study.
This retrospective cohort study examined the prevalence and appropriateness of all ambulatory antibiotic prescribing in an integrated health delivery system in the United States. The authors looked at prescribing at in-person visits and not-in-person visits (e.g. telephone, refills). Prescribing was divided into the following 5 appropriateness groups: 1) chronic antibiotic use; 2) antibiotic-appropriate; 3) potentially antibiotic-appropriate; 4) non-antibiotic-appropriate; and 5) not associated with a diagnosis. Over the 4-year study period, there were 714,057 antibiotic prescriptions ordered for 348,739 unique patients by 2,391 clinicians in 467 clinics with a patient population with a mean age of 41 years, 61% female and 78% White. Clinicians were mostly women (58%); were 78% physicians; and of those physicians were 42% primary care, 39% medical specialists, and 12% surgical specialists. The vast majority (81%) of antibiotics were prescribed at in-person visits, and 19% were not in-person visits (10% telephone, 5% orders only, and 3% refill encounters). Prescribing appropriateness was divided into 16% for chronic use, 15% antibiotic-appropriate, 39% potentially antibiotic-appropriate, 22% non-antibiotic-appropriate, and 8% not associated with a diagnosis. Prescription of antibiotics not-in-person were more likely to be chronic (20% versus 15%); less likely to be associated with appropriate or potentially appropriate diagnoses (30% versus 59%) or non-antibiotic-appropriate diagnoses (8% versus 25%); and more likely to be associated with no diagnosis (42% versus <1%).

Intravenous to oral antibiotic switch therapy among patients hospitalized with community-acquired pneumonia.
The purpose of this retrospective cohort study was to examine clinical practice guidelines which recommend switching from intravenous (IV) to oral antibiotics once patients are clinically stable. The researchers conducted a study of adults admitted with CAP from 2010 through 2015 and initially treated with IV antibiotics at 642 US hospitals. Switching was defined as discontinuation of IV and initiation of oral antibiotics without interrupting therapy. Patients switched by hospital day 3 were considered early switchers. The study found that of 78,041 CAP patients, 6% were switched early, most frequently to fluoroquinolones. Patients switched early had fewer days on IV antibiotics, shorter duration of inpatient antibiotic treatment, shorter LOS, and lower hospitalization costs, but no significant excesses in 14-day in-hospital mortality or late ICU admission. Patients at a greater mortality risk were less likely to be switched. However, even in hospitals with relatively high switch rates, less than 15% of very low-risk patients were switched early.

Evaluation of medication regimen complexity as a predictor for mortality.
This single-center, observational cohort study of adult intensive care units (ICUs) sought to evaluate the benefit of adding medication regimen complexity-ICU scores to illness severity-based hospital mortality prediction models. While medication regimen complexity was associated with increased hospital mortality, the authors concluded from their findings that a prediction model that included medication regimen complexity only modestly improved mortality prediction.

In-office dispensing of oral targeted agents by urology practices in men with advanced prostate cancer.
Researchers investigated the dispensing oral targeted agents for advanced prostate cancer treatment directly to patients in urologists’ offices, and whether this delivery model improves access to these agents especially for Black men who are historically undertreated. Their retrospective cohort study used national Medicare data for men with advanced prostate cancer managed by urology practices with and without in-office dispensing. They concluded that this model of delivery could improve access to this class of medications.

A gender-based secondary analysis of the ADAPT-2 combination naltrexone and bupropion treatment for methamphetamine use disorder trial.
This study’s objective was to determine if there were gender-based differences in treatment for methamphetamine use disorder (MUD) in general comparing treatment with placebo and due to use of a hormonal method of contraception (HMC). This research was a secondary analysis of ADAPT-2, a randomized, double-blind, placebo-controlled, multicenter, two-stage sequential parallel comparison design trial. This cohort study comprised 126 women (403 total participants); average age of 40.1 years with moderate to severe MUD. At baseline, women used methamphetamine intravenously fewer days than men [15.4 versus 23.1% days] and more women than men had anxiety (59.5 versus 47.6%). Of the 113 women capable of becoming pregnant, 31 used HMC. Treatment response for women was 29% in Stage 1 and 5.6% in Stage 2 compared with 3.2% and 0% on placebo, respectively. A treatment effect was found independently for females and males; with no between-gender treatment effect (0.144 females versus 0.100 males). Treatment effect did not differ by HMC use (0.156 HMC versus 0.128 none).

Antipsychotic medication use in Medicaid-insured children decreased substantially between 2008 And 2016.
In the early 2000s there was a rapid growth of pediatric antipsychotic prescribing, especially in the Medicaid population, and concerns grew about the safety and appropriateness of such prescribing. Numerous states implemented policy and educational programs focused on safer and more stringent utilization of antipsychotics. Antipsychotic utilization leveled off toward the end of the 2000s, but no recent national trend estimates of antipsychotic utilization in children enrolled in Medicaid exist. The authors of this study report a substantial decrease in antipsychotic use among children ages 2-17 between 2008 and 2016. Declines existed across foster care status, age, sex, and racial and ethnic groups studied. The rate of children with an antipsychotic prescription who received any diagnosis related to a pediatric indication that was approved by the Food and Drug Administration increased from 38 percent in 2008 to 45 percent in 2016.

Association of direct oral anticoagulation management strategies with clinical outcomes for adults with atrial fibrillation.
This study investigated the impact of an anticoagulation management service (AMS) on clinical outcomes of adults with atrial fibrillation (AF). This retrospective cohort study was conducted in 3 Kaiser Permanente regions, with each region taking a slightly different approach to direct oral anticoagulant (DOAC) care. These approaches included (1) usual care (UC) by the prescribing clinician, (2) UC plus an automated population management tool (PMT), or (3) pharmacist-managed AMS care. The study included 44,746 adults with a diagnosis of AF who initiated DOAC or warfarin between August 2016 and January 1, 2020, 6182 in the UC model, 33,624 in the UC plus PMT care model, and 4939 in the AMS care model. Baseline characteristics (mean age, 73.1 years, 56.1% male, 67.2% non-Hispanic White, median CHA2DS2-VASc [congestive heart failure, hypertension, age ≥75 years, diabetes, stroke, vascular disease, age 65-74 years, female sex] score of 3 [IQR, 2-5]) were well balanced after inverse probability of treatment weighting (IPTW). The cohort was followed over a median of 2 years, and patients who received the UC plus PMT or AMS care model did not have significantly better outcomes than those who received only UC.

Association of urine fentanyl concentration with severity of opioid withdrawal among patients presenting to the emergency department.
This study’s aim was to determine whether urine fentanyl concentration is associated with severity of opioid withdrawal. The study was conducted in 3 emergency departments in an urban, academic health system from January 1, 2020, to December 31, 2021. It included patients with opioid use disorder, detectable urine fentanyl or norfentanyl, and Clinical Opiate Withdrawal Scale (COWS) recorded within 6 hours of urine drug testing. Primary exposure measured was urine fentanyl concentration stratified as high (>400 ng/mL), medium (40-399 ng/mL), or low (<40 ng/mL). COWS was used to measure opioid withdrawal severity within 6 hours before or after urine specimen collection. A total of 1127 patients were included in the sample, with a mean age (SD) of 40.0 (10.7), 384 (34.1%) identified as female, 332 (29.5%) reported their race/ethnicity as non-Hispanic Black, and 658 (58.4%) reported their race/ethnicity as non-Hispanic White. For patients with high urine fentanyl concentrations, the adjusted mean COWS was 4.4 (3.9-4.8) compared with 5.5 (5.1-6.0) among those with medium and 7.7 (6.8-8.7) among those with low fentanyl concentrations.

Patient, caregiver, and clinician experience with a technologically enabled pillbox: a qualitative study.
The purpose of this study was to explore whether medication safety could be improved by the use of a technologically-enabled pillbox prescribed to patients at hospital discharge. The study included semi-structured telephone interviews with patients, patient caregivers, and inpatient and outpatient clinicians who participated in the Smart Pillbox Transition Study. The researchers utilized the Systems Engineering Initiative for Patient Safety (SEIPS) framework to develop an interview guide, which included the a priori domains of 1) barriers to implementation, 2) facilitators of the intervention, and 3) general feedback regarding experience with the intervention. The study found patient-endorsed barriers in the theme of technology and tools included signal issues, inappropriate alarms, and portability. Barriers in the theme of logistics and tasks included coordination with pharmacists in the event of a prescription change. Barriers mentioned by clinicians included patients who were poor fits for the intervention and competing demands at discharge (under the themes of personnel and patients, and logistics and tasks, respectively). Facilitators that were reported often by patients and caregivers in the theme of technology and tools included useful alarms and ease of use. Clinicians reported that communication with pharmacy and study staff facilitated the intervention.

Time to confirmatory study initiation after accelerated approval of cancer and noncancer drugs in the US.
The FDA requires that studies must be conducted to confirm a drug’s clinical benefit, but the accelerated approval pathway has been criticized because of delays by manufacturers in completing the studies. A possible source of delays is that the needed confirmatory studies are often not taking place at the time of accelerated approval. The aim of this study was to explore and compare the time elapsed between the accelerated approval of cancer and noncancer drugs to the commencement of confirmatory studies in the United States. The study found that for 103 cancer–indication pairs and noncancer products, 20.31% of confirmatory studies were not underway at the time of accelerated approval, and the median time from approval to study initiation was 1.41. Noncancer products had a greater proportion of confirmatory studies with initiation occurring after accelerated approval and a longer median time from approval to study initiation compared with cancer product–indication pairs. When evaluating delays in confirmatory study completion, studies underway at the time of accelerated approval were less likely to be submitted past FDA-designated deadlines relative to studies initiated after approval. Similar patterns were observed for cancer and noncancer products, but delays in confirmatory study completion were more distinct within studies commenced after approval for noncancer products than for cancer product–indication pairs.

Comparison of guideline concordant antibiotic prophylaxis in Veterans Affairs and non-Veterans Affairs dental settings among those with cardiac conditions or prosthetic joints.
The objective of this retrospective study was to compare prescribing of antibiotic prophylaxis in Veterans Affairs (VA) and non-VA settings. Subjects were veteran and non-veteran dental patients with cardiac conditions or prosthetic joints; most were males aged 55 years older. The results showed that VA settings had a higher prevalence of guideline concordant prescribing among those with prosthetic joints, and when assessing dosing errors. The authors recommended that future studies focus on the extent to which integrated electronic health records may be responsible for increased guideline concordant prescribing in the VA setting.

Adherence to antimicrobial prophylaxis guidelines for elective surgeries across 825 US hospitals, 2019-2020.
This retrospective cohort study assessed adherence to surgical antimicrobial prophylaxis guidelines for elective surgeries across 825 US hospitals from 2019 to 2020. The authors looked at adults who underwent elective craniotomy, hip replacement, knee replacement, spinal procedure, or hernia repair in 2019-2020 at hospitals in the PINC AI (Premier) Healthcare Database. They evaluated adherence of prophylaxis regimes, with respect to antimicrobial agents endorsed in the American Society of Health-System Pharmacist guidelines, accounting for patient antibiotic allergy and methicillin-resistant Staphylococcus aureus colonization status. They found that across 825 hospitals and 521,091 inpatient elective surgeries, 59% were adherent to prophylaxis guidelines. The most common reason found for nonadherence was unnecessary vancomycin use. Patients receiving cefazolin plus vancomycin had 19% higher odds of acute kidney injury (AKI) compared with patients receiving cefazolin alone.

A mathematical model of SARS-CoV-2 immunity predicts paxlovid rebound.
Researchers used a parsimonious mathematical model of immunity to SARS-CoV-2 infection to model the effect of nirmatrelvir/ritonavir (Paxlovid), an oral antiviral medication, in unvaccinated and vaccinated patients. Model simulations showed that viral rebound after treatment occurred only in vaccinated patients; unvaccinated treated with Paxlovid did not experience rebound in viral load. The researchers concluded that an approach combining parsimonious models of the immune system could be used to gain important insights in the context of emerging pathogens.

Comparative adherence trajectories of oral disease-modifying agents in multiple sclerosis.
This study’s objective was to compare the adherence trajectories of fingolimod (FIN), teriflunomide (TER), and dimethyl fumarate (DMF) users with multiple sclerosis (MS) as there is limited evidence regarding the comparative adherence patterns of different oral disease-modifying agents (DMAs). The authors used data from the IBM MarketScan Commercial Claims Database from 2015 to 2019. The study cohort included adults (≥18 years) with MS (International Classification of Diseases [ICD]-9/10-Clinical Modification [CM]:340/G35) diagnosis and ≥1 DMA prescription. 1913 patients with MS who were initiated with FIN (24.2%, n = 462), TER (24.0%, n = 458), and DMF (51.9%, n = 993) during 2016-2018 were included. The adherence rate among FIN, TER, and DMF users was found to be 70.8% (n = 327), 59.6% (n = 273), and 61.0% (n = 606), respectively. The Group-Based Trajectory Modeling (GBTM) grouped patients into three adherence trajectories: Complete Adherers-59.1%, Slow Decliners-22.6%, and Rapid Discontinuers-18.3%. DMF and TER users had higher odds to be rapid discontinuers than FIN users. In addition, TER users were more likely to be slow decliners compared with FIN users.

Is the number of prescriptions an appropriate metric for outpatient antimicrobial consumption? A comparison between the prescription counts and days supplied.
Monitoring antibiotic use is essential for encouraging the appropriate use of antibiotics. However, defining appropriate metrics presents multiple challenges. The purpose of this study was to compare 2 metrics for antibiotic outpatient consumption at the Veterans Health Administration (VHA) pharmacies: the number of prescriptions in EMRs and the number of dispensed days, or days supplied. During the study period, 13,373,460 clinic visits (5.0%) of the 265,613,607 total clinic visits had an antibiotic prescription, and the total of days supplied was 182,793,572. The study found that the mean days supplied per prescription continued mainly unchanged during the study period. Comparing the number of prescriptions and days supplied normalized by the number of clinic visits, these 2 metrics changed in parallel, with only minor differences from 2010 to 2019. When the researchers focused on short-term prescriptions usually utilized for acute illnesses (14 days or less), prescription number and days supplied reflected an increasing discrepancy. The number of prescriptions underestimated the decline compared to days supplied. Alternatively, long-term prescriptions (15 days or more) reflected the opposite discrepancy. For comparisons between facilities, the researchers found considerable differences in rankings of healthcare systems based on the 2 metrics.

Tracking antimicrobial stewardship activities beyond days of therapy (DOT): comparison of days of antibiotic spectrum coverage (DASC) and DOT at a single center.
Researchers evaluated the measurement performance by days of antibiotic spectrum coverage (DASC) versus days of therapy (DOT), the preferred metric for measuring inpatient antimicrobial consumption within the U.S. Their retrospective study analyzed inpatient antimicrobial use at the Iowa City Veterans’ Affairs Healthcare System acute-care hospital. Antimicrobial DOT did not decrease significantly during a period of robust stewardship activities, but a significant downward trend in the antimicrobial spectrum, as measured by DASC was detected. The researchers concluded that the DASC metric may help to monitor the effect of stewardship activities more broadly.

Trends in dispensed prescriptions for opioids, sedatives, benzodiazepines, gabapentin, and stimulants to children by general dentists, 2012-2019.
This study examined trends in prescription fills for opioids, benzodiazepines, gabapentin, and stimulants to children <18 years from 2012 to 2019 in a national dataset comprising 92% of dispensed outpatient prescriptions by dentists. During this time, 3.8 million children filled prescriptions for high-alert drugs from general dentists. Opioids accounts for 69.4% of high-alert prescriptions, however from 2012 to 2019 fills for opioids, sedatives, benzodiazepines, and stimulants decreased by 65.2%, 43.4%, 43.6% and 89.3%, respectively. Gabapentin prescriptions increased by 8.1%. Older teenagers (15-17 years) received 42.5% of high-alert prescriptions. Low-income counties in Southern states were overrepresented among top-prescribing areas in 2019.

Implementing pharmacist-prescriber collaboration to improve evidence-based anticoagulant use: a randomized trial.
This article described a study designed to improve existing alert systems for direct oral anticoagulant medications (DOAC) by testing novel alerts that encourage collaboration between prescribers and expert pharmacists working in anticoagulation clinics. Its goals were to determine the effect of notifications targeting existing inappropriate DOAC prescriptions, to examine the effect of alerts on newly prescribed inappropriate DOACs, and to examine changes in the magnitude of effects over time for both the new and existing prescription alerts. Prescribing healthcare providers would be randomized to different types of electronic health record medication alerts when a patient has an unsafe anticoagulant prescription; the authors identified which alerts are most effective at encouraging evidence-based prescribing.

Racial and ethnic disparities in opioid access and urine drug screening among older patients with poor-prognosis cancer near the end of life.
This research characterized racial and ethnic disparities and trends in opioid access and urine drug screening (UDS) among older patients dying of cancer, and to explore potential mechanisms. Among 18,549 non-Hispanic White (White), Black, and Hispanic Medicare decedents older than 65 years with poor-prognosis cancers, the authors examined 2007-2019 trends in opioid prescription fills and potency (morphine milligram equivalents [MMEs] per day [MMEDs]) near the end of life (EOL), defined as 30 days before death or hospice enrollment. They found that between 2007 and 2019, White, Black, and Hispanic decedents experienced steady declines in EOL opioid access and rapid expansion of UDS. Compared with White patients, Black and Hispanic patients were less likely to receive any opioid (Black, -4.3 percentage points; Hispanic, -3.6 percentage points) and long-acting opioids (Black, -3.1 percentage points; Hispanic, -2.2 percentage points). They also received lower daily doses (Black, -10.5 MMED; Hispanic, -9.1 MMED) and lower total doses (Black, -210 MMEs; Hispanic, -179 MMEs). Black patients were also more likely to undergo UDS (0.5 percentage points).
