Pharmacy students' interprofessional experience and performance in advanced pharmacy practice experience rotations amid COVID-19 pandemic.

Introduction: Interprofessional education (IPE) is essential in pharmacy training, providing students with vital collaborative skills for real-world healthcare. Advanced Pharmacy Practice Experience (APPE) is integral to IPE, allowing students to apply their knowledge in diverse healthcare settings. The COVID-19 pandemic has disrupted healthcare education and raised concerns about its impact on IPE during APPE rotations. Our study investigates the pandemic's influence on pharmacy students' interprofessional interactions and APPE performance. Objective: To assess the interprofessional experiences of fourth-year pharmacy students before and during the COVID-19 pandemic in the context of APPE. Methods: This retrospective observational study examined the experiences of P4 pharmacy students in the United States during APPEs before and during the pandemic. We employed electronic surveys with 21 questions to gauge interactions and interprofessional team effectiveness, employing Likert scale response options. We compared responses between the 2019-2020 and 2020-2021 APPE rotations using statistical tests. Results: Our study encompassed 83 and 86 students for the 2019-2020 and 2020-2021 APPE rotations, respectively, achieving a 100% response rate. Amid the pandemic, written communications between pharmacy students and healthcare providers in general medicine rotations increased, while in-person engagement decreased. Pre-COVID, students reported higher colleague referrals and greater interprofessional utilization during ambulatory care rotations. Conclusion: COVID-19 shifted interactions from in-person to written communication between pharmacy students and healthcare providers. Students reported decreased satisfaction with their interprofessional experiences. This research offers insights into the changing landscape of pharmacy education, helping students prepare for evolving challenges in healthcare delivery and education.

Factors Associated with Statin Discontinuation Following Metabolic and Bariatric Surgery: A Retrospective Analysis of 2012-2021 Electronic Medical Records Network Data.

BACKGROUND: Bariatric surgery has been shown to improve hyperlipidemia, decreasing the need for statin medications. Although maintaining statin therapy post-surgery for those with a history of atherosclerotic cardiovascular disease (ASCVD) is advised, it is uncertain if discontinuation risks differ between those with and without ASCVD history. AIM: The study aims to analyze the rate and reasons for statin cessation post-bariatric surgery in the US using real-world data. METHODS: Using the TriNetX electronic medical records network from 2012 to 2021, the study involved patients aged 18 or older on statins at the time of bariatric surgery. They were categorized into primary and secondary prevention groups based on prior ASCVD. Statin discontinuation was defined as a 90-day gap post the last statin dosage. The Cox model assessed factors influencing statin cessation. RESULTS: Seven hundred and thirty-three statin users undergoing bariatric surgery were identified, with 564 (77%) in primary prevention. Six months post-surgery, 48% of primary prevention patients and 34.5% of secondary ones stopped statins. Primary prevention patients had a 30% higher likelihood of cessation compared to secondary prevention (hazard ratio, 1.30; 95% CI, 1.06-1.60) as shown by multivariable analysis. CONCLUSIONS: Post-bariatric surgery, primary prevention patients are more likely to discontinue statins than secondary prevention patients.

Metabolic and Bariatric Surgery Utilization Trends in the United States: Evidence From 2012 to 2021 National Electronic Medical Records Network.

Background: Bariatric surgery has evolved over the past 2 decades yet assessing trends of bariatric surgery utilization in the growing eligible population is lacking. Aim: This study aimed to update the trends in bariatric surgery utilization, changes in types of procedures performed, and the characteristics of patients who underwent bariatric surgery in the United States, using real-world data. Method: This retrospective descriptive observational study was conducted using the TriNetX, a federated electronic medical records network from 2012 to 2021, for adult patients 18 years old or older who had bariatric surgery. Descriptive statistical analysis was conducted to assess patients' demographics and characteristics. Annual secular trend analyses were conducted for the annual rate of bariatric surgery, and the specific procedural types and proportions of laparoscopic surgeries. Results: A steady increase in the number of procedures performed in the United States over the first 6 years of the study, a plateau for the following 2 years, and then a decline in 2020 and 2021 (during the coronavirus disease 2019 pandemic). The annual rate of bariatric surgery was lowest in 2012 at 59.2 and highest in 2018 at 79.6 surgeries per 100,000 adults. During the study period, 96.2% to 98.8% of procedures performed annually were conducted laparoscopically as opposed to the open technique. Beginning in 2012, the Roux-en-Y gastric bypass (RYGB) procedure fell to represent only 17.1% of cases in 2018, along with a sharp decline in the adjustable gastric band (AGB) procedure, replaced by a sharp increase in the sleeve gastrectomy (SG) procedure to represent over 74% of cases in 2018. Conclusions: Bariatric surgery utilization in the United States showed a moderate decline in the number of RYGB procedures, which was offset by a substantial increase in the number of SG procedures and a precipitous drop in the annual number of AGB procedures.

Utilization, reimbursement, and price trends for Hepatitis C virus medications in the US Medicaid programs: 2001-2021.

Background: Hepatitis C Virus (HCV) remains a challenging health problem worldwide, with increasing incidence despite being curable with Direct Acting Antiviral (DAA) agents. Objective: This study aimed to describe the utilization, reimbursement, and price trends of HCV treatments and evaluate the influence of treatment guidelines and policies. Methods: A retrospective, descriptive drug utilization study conducted using the outpatient pharmacy data extracted from the Centers for Medicaid and Medicare Services State Drug Utilization Data between 2001 and 2021. All HCV treatments approved in the US were included, conventional therapy (CT), and DAA agents. The annual secular trends were calculated for each medication's total number of prescriptions, reimbursements, and prices. The average reimbursement per prescription was calculated and utilized as a proxy of prices. The HCV treatment guideline and policies and legislation were evaluated overtime to measure the impact on the trends. Results: Despite CT having a higher total utilization, DAA agents commanded significantly greater reimbursements, with 4.1 billion USD for CT and 19.45 billion USD for DAA agents. CT utilization increased rapidly and dominated the market until 2011, peaking at 379,696 prescriptions in 2003 but declining afterward. DAA agents' utilization increased rapidly in their first year: i.e., sofosbuvir reached 50,377 prescriptions with 1.3 billion USD in 2014, while ledipasvir/sofosbuvir reached 79,387 prescriptions with 2 billion USD in 2015. The average price per prescription was high for the DAA agents, like 24,992 USD for sofosbuvir and 22,787 USD for ledipasvir/sofosbuvir, compared to CT medications ribavirin, around 500 USD, and pegINF, around 3000 USD. The new DAA agents replaced CT, and initiating market competition among DAA agents. Conclusion: The introduction of multiple DAA agents slightly changed their prescription prices but remained high during the study period. The recent increase in HCV incidence cases indicates accessibility issues for costly and effective DAA agents, with treatment guidelines and policies playing a critical role in shaping these trends.

Drug Expenditure, Price, and Utilization in US Medicaid: A Trend Analysis for New Multiple Myeloma Medications from 2016 to 2022.

INTRODUCTION: Multiple myeloma (MM) is the most common plasma cell tumor type. In late 2015, the FDA approved three new medications for MM. These medications were ixazomib, daratumumab, and elotuzumab. However, their utilization, reimbursement, and price in the Medicaid program have not been analyzed before. METHODS: A retrospective drug utilization study using the national Medicaid pharmacy claims data from 2016 to 2022 in the US. The primary metrics of analysis were utilization (number of prescriptions), reimbursement (total spending), and price (reimbursement per prescription). RESULTS: The overall Medicaid utilization of MM medications increased from 1671 prescriptions in 2016 to 34,583 prescriptions in 2022 (1970% increase). Moreover, the overall Medicaid reimbursement for the new MM medications increased from USD 9,250,000 in 2016 to over USD 214,449,000 in 2022 (2218% increase). Daratumumab had much higher utilization, reimbursement, and market shares than its competitors. Ixazomib was the most expensive medication compared to daratumumab and elotuzumab. CONCLUSION: The results of this study demonstrate that CMS utilization and spending on MM medications have significantly grown since 2016. Daratumumab has by far the highest utilization, spending, and market share. The utilization of and spending on specific pharmaceuticals are clearly impacted by policy and clinical guideline recommendations.

Descriptive analysis of reported adverse events associated with anti-obesity medications using FDA Adverse Event Reporting System (FAERS) databases 2013-2020.

Background Obesity is a globally growing health problem, and its treatment has been challenging. The use of anti-obesity medications (AOMs) has been associated with severe adverse events (AEs). Several AOMs have been withdrawn from the market owing to documented AEs. Aim To describe, estimate and characterize the frequency of AEs attributable to the use of the AOMs, and investigate previously unreported potential AEs associated with AOMs. Method Using the US FDA Adverse Event Reporting System (FAERS) between January 2013 and June 2020, a retrospective, descriptive analysis was conducted to analyze all major reported AEs and outcomes including death, life-threatening, hospitalization, disability, and required intervention or congenital anomaly. The total numbers of AEs reports, cases, adverse reactions and outcomes were calculated for each medication. Results A total of 18,675 unique AEs reports associated with AOMs used for 15,143 patients. The mean age was 49.8 years [SD 1.83], while most patients were female adults (73.4%). The most frequently reported AEs were nausea and vomiting, followed by dizziness and headache, drug ineffectiveness, cardiovascular diseases, and kidney complications. There were 21,229 unique outcomes, including 1039 deaths (fatality ratio of 4.9% of all analyzed reports), 1613 (7.6%) life-threatening events, 7426 (35%) hospitalizations, and 1249 (5.9%) disability cases. Phentermine/topiramate fatal cases represent 6% of the overall medication's reported AEs. Cardiovascular AEs represented 31%, 23%, and 22% of phentermine, liraglutide, and phentermine/topiramate total AEs, respectively. Conclusion The analysis of FAERS database revealed numerous serious AEs associated with AOMs. These AEs can lead to serious cardiovascular and kidney complications. It is necessary to continue and systematically monitor safety of AOMs' to optimize patient anti-obesity therapy.

Changes in utilization of immediate-release, extended-release, and liquid formulation medications relative to bariatric surgery: a segmented regression analysis.

BACKGROUND: Changes in gut anatomy following bariatric surgery impacts medication absorption, often requiring changes in medication formulations. OBJECTIVES: To assess changes in utilization of extended-release (ER), immediate-release (IR), and liquid formulations 360 days before and after bariatric surgery. SETTING: Large U.S. administrative claims database of privately insured beneficiaries, January 2005 through December 2018. METHODS: We included patients aged ≥18 years with 360 days of continuous enrollment before and after date of bariatric surgery (Roux-en-Y gastric bypass [RYGB] or sleeve gastrectomy [SG]). The proportion of each formulation (ER, IR, or liquid) of oral prescription medications filled during the study period were assessed in twelve 30-day windows before and after bariatric surgery and stratified by bariatric surgery type. Segmented regression analysis was used to assess filled medication categorized by formulation before and after bariatric surgery overall and RYGB relative to SG. RESULTS: Among 122,866 included patients, there were increases in the proportion of patients on each formulation before and after surgery attributed to proton pump inhibitors, opioids, antiemetics, and ursodiol. After removing these acutely used medications, we found a 40% immediate reduction in patients on ER medications (P < .0001), 15% immediate reduction in patients on IR medications (P < .0001), and a nonsignificant increase in patients on liquid formulations (P = .1340). CONCLUSION: Despite reductions in ER formulations, many patients continued on this formulation which may potentially contribute to poor outcomes.

Evaluation of statin discontinuation stratified by primary versus secondary prevention following bariatric surgery: a retrospective cohort study.

BACKGROUND: Bariatric surgery leads to an improvement in hyperlipidemia and a subsequent decline in the use of hyperlipidemia-related medications, including statins. In patients with a history of atherosclerotic cardiovascular disease (ASCVD), it is recommended to continue statins; however, it is unknown whether there is a differential risk for statin discontinuation in patients with and without a history of ASCVD. OBJECTIVES: To estimate the rates and factors associated with statin discontinuation following bariatric surgery. SETTING: Large U.S. administrative claims database of privately insured beneficiaries, January 2005 through December 2017. METHODS: We identified patients aged ≥19 years who were statin users at the time of bariatric surgery. Patients were stratified into primary prevention and secondary prevention (patients with a history of ASCVD) groups. Time to statin discontinuation was defined as the first 90-day gap after exhausting the last day's supply of the last statin prescription. Factors associated with statin discontinuation were assessed using the Cox proportional hazards regression model. RESULTS: We identified 19,332 statin users at the time of bariatric surgery, of whom 84% (16,221) used statins for primary prevention. At 6 months, 62% and 53% of patients in the primary and the secondary prevention treatment groups, respectively, discontinued statin use. Patients in the primary prevention treatment group were 18% more likely to discontinue statin therapy compared with the patients in the secondary prevention treatment group (hazard ratio, 1.18; 95% confidence interval, 1.13-1.24) according to a multivariable analysis. CONCLUSIONS: Our findings suggest that the rate of discontinuation of statin therapy after bariatric surgery was more pronounced in the primary versus secondary prevention treatment group.
