The U.S. Department of Veterans Affairs (VA) is the largest integrated healthcare system in the United States and provides dental care to approximately one-half million veterans annually. In response to the opioid crisis, the VA released several opioid risk mitigation strategies. Although opioid prescribing by VA dentists has decreased on the whole, the implementation experiences at the level of dentists remains unclear. Our objective was to explore the barriers and facilitators that affect opioid decision making for management of acute dental pain among VA dentists. Dentists practicing in the VA facilities with the highest and lowest volume of opioid prescriptions were recruited. Standardized qualitative interviews by telephone followed a semistructured guide designed around the Capability (C), Opportunity (O), Motivation (M), and Behaviour (B) model. Audio recordings were transcribed and independently double-coded using NVivo to identify potential targets for future guideline-based opioid interventions. Of 395 eligible general and specialty dentists, 90 (24.8%) completed an interview representing 33 VA facilities. Opportunities for prescribing opioids included 1) completion of dental procedures associated with acute dental pain, 2) caring for patients who presented with existing dental pain, and 3) responding to patient opioid requests. Capabilities included using resources (eg, electronic medical records), clinical judgement (eg, evaluation of medical history including medication use), communication skills, and ability to screen for opioid misuse. Motivation themes focused on alleviating patients' acute dental pain. Barriers and facilitators of opioid prescribing varied across facilities. The results can offer intervention targets for continued opioid risk mitigation efforts.

We assessed trends in treatment of patients with CRE from 2012 through 2018. We detected decreased utilization of aminoglycosides and colistin and increased utilization in extended-spectrum cephalosporins and ceftazidime-avibactam. We found significant uptake of ceftazidime-avibactam, a newly approved antibiotic, to treat CRE infections.

BACKGROUND: No research has been conducted to assess whether antibiotic prophylaxis prescribing differs by dental setting. Therefore, the goal of this study was to compare the prescribing of antibiotic prophylaxis in Veterans Affairs (VA) and non-Veterans Affairs settings.

METHODS: This was a retrospective study of veteran and non-veteran dental patients with cardiac conditions or prosthetic joints between 2015-2017. Multivariable log binomial regression analysis was conducted to compare concordant prescribing by setting with a sub-analysis for errors of dosing based on antibiotic duration (i.e., days prescribed).

RESULTS: A total of 61,124 dental visits that received a prophylactic antibiotic were included. Most were male (61.0%), and 55 years of age or older (76.2%). Nearly a third (32.7%) received guideline concordant prophylaxis. VA dental settings had a lower prevalence of guideline concordant prescribing compared to non-VA settings in unadjusted results (unadjusted prevalence ratio [uPR] = 0.92, 95% CI: 0.90-0.95). After adjustment, prevalence of guideline concordant prescribing was higher in those with prosthetic joints in the VA setting (adjusted prevalence ratio [aPR] = 1.73, 95% CI: 1.59-1.88), with no difference identified in those without a prosthetic joint (aPR = 0.99, 95% CI: 0.96-1.01). Concordance of dosing was higher in VA compared to non-VA settings (aPR = 1.11, 95% CI: 1.07-1.15).

CONCLUSIONS: VA has a higher prevalence of guideline concordant prescribing among those with prosthetic joints and when assessing dosing errors. Though the presence of an integrated electronic health record (EHR) may be contributing to these differences, other system or prescriber-related factors may be responsible. Future studies should focus on to what extent the integrated EHR may be responsible for increased guideline concordant prescribing in the VA setting.

OBJECTIVES: Opioids prescribed by dentists have been associated with serious adverse events, including opioid-related overdose and mortality. However, the downstream outcomes of opioids prescribed by dentists to Veterans who are at high risk for opioid misuse and overdose have yet to be determined.

METHODS: This was a national cross-sectional analysis of opioids associated with dental visits within the Veterans Health Administration from 2015 to 2018. Overprescribing was defined per guidelines as >120 morphine milligram equivalents (MME) or >3 days supply. The association of dental visit and patient characteristics was modeled separately for opioid-related poisoning and all-cause mortality using logistic regression.

RESULTS: Of 137,273 Veterans prescribed an opioid by a dentist, 0.1% and 1.1% were associated with opioid-related poisoning and mortality, respectively. There was no difference in opioid poisoning within 6 months for Veterans with opioid prescriptions >120 MME (aOR = 1.25 [CI: 0.89-1.78]), but poisoning decreased in Veterans prescribed opioids >3-days supply (aOR = 0.68 [CI: 0.49-0.96]). However, Veterans with opioids >120 MME were associated with higher odds of mortality within 6 months (aOR = 1.17 [95% CI: 1.05-1.32]) while there was no difference in prescriptions >3-days supply (aOR = 1.12 [CI: 0.99-1.25]).

CONCLUSION: Serious opioid-related adverse events were rare in Veterans and lower than other reports in the literature. Since nonopioid analgesics have superior efficacy for the treatment of acute dental pain, prescribing opioid alternatives may decrease opioid-related poisoning. Strategies for dentists to identify patients at high risk should be incorporated into the dental record.

PURPOSE: Opioids, benzodiazepines and sedatives can manage dental pain, fear and anxiety but have a narrow margin of safety in children. General dentists may inappropriately prescribe gabapentin and stimulants. National evidence on dispensing rates of these high-alert medicines by dentists to children is limited.

METHODS: We utilize join-point regression to identify changes in fills for opioids, sedatives, benzodiazepines, gabapentin, and stimulants to children <18 years from 2012 to 2019 in a national dataset comprising 92% of dispensed outpatient prescriptions by dentists.

RESULTS: From 2012 to 2019, 3.8 million children filled prescriptions for high-alert drugs from general dentists. National quarterly dispensing of high-alert drugs decreased 63.1%, from 10456.0 to 3858.8 days per million. Opioids accounted for 69.4% of high-alert prescriptions. From 2012 to 2019, fills for opioids, sedatives, benzodiazepines, and stimulants decreased by 65.2% (7651.8 to 2662.7), 43.4% (810.9 to 458.7), 43.6% (785.7 to 442.7) and 89.3% (825.6 to 88.6 days per million), respectively. Gabapentin increased 8.1% (121.8 to 131.7 days per million). A significant decrease in high-alert fills occurred in 2016, (-6.0% per quarter vs. -1.6% pre-2016, P-value<0.001), especially for opioids (-7.0% vs. -1.2%, P-value<0.001). Older teenagers (15-17 years) received 42.5% of high-alert prescriptions. Low-income counties in the South were overrepresented among top-prescribing areas in 2019.

CONCLUSIONS: We found promising national decreases in fills for high-alert medicines to children by general dentists from 2012 to 2019. However, older teenagers and children in some counties continued to receive dental opioids at high rates. Future efforts should address non-evidence-based pain management in these groups.

BACKGROUND: Drug shortages are a complex global challenge, and few studies have analyzed quantitative data on their impacts. In September 2019, detection of a nitrosamine impurity in ranitidine led to recalls and shortages.

AIMS: We investigated the extent of the ranitidine shortage and its impacts on acid suppression drug utilization in Canada and the United States (US).

METHODS: We conducted an interrupted time series analysis of acid suppression drug purchases in Canada and the US from 2016 through 2021 using IQVIA's MIDAS database. We used autoregressive integrated moving average models to determine the impact of the shortage on purchasing rates for ranitidine, other histamine-2 receptor antagonists (H2RAs), and proton pump inhibitors (PPIs).

RESULTS: Prior to the recalls, 20,439,915 ranitidine units were purchased monthly in Canada and 189,038,496 in the US on average. After the recalls started in September 2019, purchasing rates decreased for ranitidine (Canada p = 0.0048, US p < 0.0001) and increased for non-ranitidine H2RAs (Canada p = 0.0192, US p = 0.0534). One month into the recalls, purchasing rates dropped by 99% (Canada) and 53% (US) for ranitidine and increased by 128.3% (Canada) and 37.3% (US) for non-ranitidine H2RAs. PPI purchasing rates did not change significantly in either country.

CONCLUSIONS: The ranitidine shortage led to immediate and sustained shifts in H2RA utilization in both countries, potentially affecting hundreds of thousands of patients. Our results emphasize the need for future studies of the clinical and financial implications of the shortage, and the importance of ongoing work to mitigate and prevent drug shortages.

OBJECTIVE: The aim of the study is to characterize patient-reported signs and symptoms of urinary tract infections in patients with neurogenic bladder to inform development of an intervention to improve the accuracy of urinary tract infection diagnosis.

DESIGN: This is a retrospective cohort study of adults with neurogenic bladder due to spinal cord injury/disorder, multiple sclerosis, and/or Parkinson disease and urinary tract infection encounters at four medical centers between 2017 and 2018. Data were collected through medical record review and analyzed using descriptive statistics and unadjusted logistic regression.

RESULTS: Of 199 patients with neurogenic bladder and urinary tract infections, 37% were diagnosed with multiple sclerosis, 36% spinal cord injury/disorder, and 27% Parkinson disease. Most patients were men (88%) in inpatient or long-term care settings (60%) with bladder catheters (67%). Fever was the most frequent symptom (32%). Only 38% of patients had a urinary tract-specific symptom; 48% had only nonspecific to the urinary tract symptoms. Inpatient encounter setting (odds ratio, 2.5; 95% confidence interval, 1.2-5.2) was associated with greater odds of only having nonspecific urinary tract symptoms.

CONCLUSIONS: In patients with neurogenic bladder and urinary tract infection encounters, nonspecific signs and symptoms are most frequently reported. These results can inform interventions to help providers better elicit and document urinary tract-specific symptoms in patients with neurogenic bladder presenting with possible urinary tract infection, particularly among hospitalized patients.

PURPOSE: To report historical patterns of pharmaceutical expenditures, to identify factors that may influence future spending, and to predict growth in drug spending in 2023 in the United States, with a focus on the nonfederal hospital and clinic sectors.

METHODS: Historical patterns were assessed by examining data on drug purchases from manufacturers using the IQVIA National Sales Perspectives database. Factors that may influence drug spending in hospitals and clinics in 2023 were reviewed, including new drug approvals, patent expirations, and potential new policies or legislation. Focused analyses were conducted for biosimilars, cancer drugs, diabetes medications, generics, COVID-19 pandemic influence, and specialty drugs. For nonfederal hospitals, clinics, and overall (all sectors), estimates of growth of pharmaceutical expenditures in 2023 were based on a combination of quantitative analyses and expert opinion.

RESULTS: In 2022, overall pharmaceutical expenditures in the US grew 9.4% compared to 2021, for a total of $633.5 billion. Utilization (a 5.9% increase), price (a 1.7% increase) and new drugs (a 1.8% increase) drove this increase. Adalimumab was the top-selling drug in 2022, followed by semaglutide and apixaban. Drug expenditures were $37.2 billion (a 5.9% decrease) and $116.9 billion (a 10.4% increase) in nonfederal hospitals and clinics, respectively. In clinics, new products and increased utilization growth drove growth, with a small impact from price changes. In nonfederal hospitals, a drop in utilization led to a decrease in expenditures, with price changes and new drugs contributing to growth in spending. Several new drugs that will influence spending have been or are expected to be approved in 2023. Specialty and cancer drugs will continue to drive expenditures along with the evolution of the COVID-19 pandemic.

CONCLUSION: For 2023, we expect overall prescription drug spending to rise by 6.0% to 8.0%, whereas in clinics and hospitals we anticipate increases of 8.0% to 10.0% and 1.0% to 3.0%, respectively, compared to 2022. These national estimates of future pharmaceutical expenditure growth may not be representative of any particular health system because of the myriad of local factors that influence actual spending.

INTRODUCTION: The purpose of this study is to compare opioid prescribing and high-risk prescribing by race and ethnicity in a national cohort of U.S. veterans.

METHODS: A cross-sectional analysis of veteran characteristics and healthcare use was performed on electronic health record data for 2018 Veterans Health Administration users and enrollees in 2022.

RESULTS: Overall, 14.8% received an opioid prescription. The adjusted odds of being prescribed an opioid were lower for all race/ethnicity groups than for non-Hispanic White veterans, except for non-Hispanic multiracial (AOR=1.03; 95% CI=0.999, 1.05) and non-Hispanic American Indian/Alaska Native (AOR=1.06; 95% CI=1.03, 1.09) veterans. The odds of any day of overlapping opioid prescriptions (i.e., opioid overlap) were lower for all race/ethnicity groups than for the non-Hispanic White group, except for the non-Hispanic American Indian/Alaska Native group (AOR=1.01; 95% CI=0.96, 1.07). Similarly, all race/ethnicity groups had lower odds of any day of daily dose >120 morphine milligram equivalents than the non-Hispanic White group, except for the non-Hispanic multiracial (AOR=0.96; 95% CI=0.87, 1.07) and non-Hispanic American Indian/Alaska Native (AOR=1.06; 95% CI=0.96, 1.17) groups. Non-Hispanic Asian veterans had the lowest odds for any day of opioid overlap (AOR=0.54; 95% CI=0.50, 0.57) and daily dose >120 morphine milligram equivalents (AOR=0.43; 95% CI=0.36, 0.52). For any day of opioid-benzodiazepine overlap, all races/ethnicities had lower odds than non-Hispanic White. Non-Hispanic Black/African American (AOR=0.71; 95% CI=0.70, 0.72) and non-Hispanic Asian (AOR=0.73; 95% CI=0.68, 0.77) veterans had the lowest odds of any day of opioid-benzodiazepine overlap.

CONCLUSIONS: Non-Hispanic White and non-Hispanic American Indian/Alaska Native veterans had the greatest likelihood to receive an opioid prescription. When an opioid was prescribed, high-risk prescribing was more common in White and American Indian/Alaska Native veterans than in all other racial/ethnic groups. As the nation's largest integrated healthcare system, the Veterans Health Administration can develop and test interventions to achieve health equity for patients experiencing pain.

INTRODUCTION: In the United States, dentists frequently prescribe hydrocodone. In October 2014, the US Drug Enforcement Administration rescheduled hydrocodone from controlled substance schedule III to II, introducing more restricted prescribing and dispensing regulations, which may have changed dental prescribing of opioids.

OBJECTIVE: The study aim was to evaluate the impact of the hydrocodone rescheduling on dental prescribing of opioids in the United States.

METHODS: This was a cross-sectional study of opioids prescribed by dentists between October 2012 and October 2016, using the IQVIA Longitudinal Prescription Dataset. Monthly dentist-based opioid prescribing rate (opioid prescription [Rx]/1,000 dentists) and monthly average opioid dosages per prescription (mean morphine milligram equivalent per day [MME/d]) were measured in the 24 mo before and after hydrocodone rescheduling in October 2014 (index or interruption). An interrupted time-series analysis was conducted using segmented ordinary least square regression models, with Newey-West standard errors to handle autocorrelation.

RESULTS: Dentists prescribed 50,412,942 opioid prescriptions across the 49 mo. Hydrocodone was the most commonly prescribed opioid pre- and postindex (74.9% and 63.8%, respectively), followed by codeine (13.8% and 21.6%), oxycodone (8.1% and 9.5%), and tramadol (2.9% and 4.8%). At index, hydrocodone prescribing immediately decreased by -834.8 Rx/1,000 dentists (95% confidence interval [CI], -1,040.2 to -629.4), with increased prescribing of codeine (421.9; 95% CI, 369.7-474.0), oxycodone (85.3; 95% CI, 45.4-125.2), and tramadol (111.8; 95% CI, 101.4-122.3). The mean MME increased at index for all opioids except for hydrocodone, and dosages subsequently decreased during the postindex period.

CONCLUSION: Following the rescheduling, dentist prescribing of hydrocodone declined while prescribing of nonhydrocodone opioids increased. Understanding the impact of this regulation informs strategies to ensure appropriate prescribing of opioids for dental pain.

KNOWLEDGE TRANSFER STATEMENT: The study findings can be used by policy makers to make informed decisions in developing future risk mitigation strategies aimed to regulate opioid prescribing behaviors. Furthermore, dentist-specific resources and guidelines are needed subsequent to these policies in order to meet the dental population needs.
