School closures and prescription medication use among children and adolescents before and during the COVID-19 pandemic in the USA, 2019-2022.

The impact of schools closing for in-person instruction in the USA during the COVID-19 pandemic on the use of prescription medications is not known. In this study, we examined changes in the total prescriptions filled, specifically for attention deficit hyperactivity disorder (ADHD) medications, among school-aged children and adolescents aged 10-19 years during periods before and after complete school closures between October 2019 and September 2022. Our findings indicate that complete school closures were associated with declines in the use of ADHD medications among younger populations in the USA. These findings suggest that the underuse of ADHD medications may be an overlooked contributor to declines in academic performance observed during periods of school closures during the COVID-19 pandemic.

Use of Oral and Emergency Contraceptives After the US Supreme Court's Dobbs Decision.

Importance: The US Supreme Court Dobbs v Jackson Women's Health Organization decision allowed states to strengthen restrictions on abortion access, triggering the closure of family planning clinics and leading to confusion about the legality of emergency contraceptives (ECs). Objectives: To evaluate the association between the Dobbs decision and fills for oral and emergency contraceptives in states that enacted the most restrictive abortion policies after Dobbs. Design, Setting, and Participants: This cohort study used data on contraceptive fills for women of reproductive age (15-49 years) in the US from IQVIA's National Prescription Audit PayerTrak and data from the Guttmacher Institute were used to categorize changes in abortion restrictions in each state. A difference-in-differences analysis compared changes in monthly fill rates for daily oral contraceptive pills (OCPs) and ECs in states that became most restrictive (implemented a full abortion ban after Dobbs) and comparison states (kept a medium level of abortion restrictions after Dobbs) before (March 2021 to November 2021) and after (July 2022 to October 2023) the Dobbs decision. Exposure: State-level abortion restrictions. Main Outcomes and Measures: Monthly fills of OCPs and ECs per 100 000 women of reproductive age. Results: Between March 2021 and October 2023, 142.8 million prescriptions for OCPs and 904 269 prescriptions for ECs were dispensed at US retail pharmacies. Before Dobbs, trends in monthly fill rates were similar for OCPs and ECs between the most restrictive and comparison states. After the Dobbs decision, states that became the most restrictive experienced an additional 4.1% decline in OCP fills with 285.9 fewer fills per 100 000 (95% CI, -495.8 to -6.8; P = .04). In contrast to OCPs, fills for ECs increased during the first year after Dobbs (July 2022 to June 2023) in both groups of states. However, 1 year after Dobbs (July 2023 to October 2023), the most restrictive states experienced an additional 65% decrease in emergency contraceptive fills with 13.2 fewer fills per 100 000 (95% CI, -27.2 to -4.1; P = .01). Conclusions and Relevance: In this cohort study of prescriptions filled at US pharmacies, the Dobbs decision was associated with declines in oral contraceptives, particularly ECs, in states enacting the most restrictive abortion policies. Given the important role of OCPs and ECs in preventing pregnancy and the need for abortion, efforts to improve access may be needed, especially in states where legal abortion is no longer an option.

Changes in HIV Pre-exposure Prophylaxis (PrEP) Coverage at State and County Level During the COVID-19 Pandemic in the United States.

This study quantifies the prevalence and trends in weekly PrEP coverage at the national, state and county-level, before and during the COVID-19 pandemic in the United States.We estimated weekly PrEP coverage using longitudinal individual-level pharmacy claims from IQVIA LRx for a cohort of PrEP users (N = 287,493) ages 16 to 85 years between December 29th, 2019 and November 8th, 2020. Weekly PrEP coverage was defined as PrEP use among individuals at high risk for HIV. We conducted an interrupted time series analysis to quantify changes in weekly PrEP coverage before (December 29th, 2019 - March 8th, 2020) and during (March 29th - November 8th, 2020) the COVID-19 pandemic at the national, state and county-level by county characteristics, specifically by EHE priority jurisdiction, racial/ethnic composition, and urbanity. Nationally, weekly PrEP coverage among individuals ages 16 to 85 at high risk for HIV declined by 11.5% (from 11.0% before to 9.5% during the pandemic; t = 8.02,p < 0.01). Weekly PrEP coverage declined in all states and most counties yet varied substantially across states and counties. Geographic disparities in weekly PrEP coverage were also observed between urban EHE priority counties with significantly lower rates in counties with ≥ 50% Black/Latinx population when compared to their counterparts (7.9% vs. 11.2%; t = 18.91,p < 0.01);these disparities were most pronounced in California and New York. Weekly PrEP coverage was much lower than the 25% annual coverage reported by the Centers for Disease Control and geographic disparities observed within states likely contribute to the persistent racial/ethnic disparities in new HIV diagnoses observed within those states.

Changes in anticoagulant and antiplatelet drug supply at US hospitals before and during the COVID-19 pandemic (2018-2021).

PURPOSE: Antithrombotic agents have a role in coronavirus disease 2019 (COVID-19) treatment, but the pandemic disrupted medication supply. This study examined changes in the volume of oral and parenteral anticoagulant and antiplatelet medications at US hospitals during the pandemic. METHODS: IQVIA National Sales Perspective (NSP) data was used to determine the monthly volume of anticoagulants and antiplatelets purchased at US hospitals between January 2018 and February 2021. Mean monthly medication volumes, reported as extended units (EUs), and year-over-year changes in medication volume were determined. A single-group interrupted time series analysis was used to evaluate changes in the rate of growth of monthly medication volumes before (January 2019-February 2020) and during (March 2020-February 2021) the COVID-19 pandemic. RESULTS: Overall, there was a 43.4% decline in the total volume of anticoagulants and antiplatelets at US hospitals in March 2020, driven by a decrease in heparin volume. Mean monthly volumes decreased significantly (P < 0.05) for parenteral anticoagulants (-106,691,340 EU [95% CI, -200,033,910 to -13,348,780]), oral anticoagulants (-354,800 EU [95% CI, -612,180 to -97,420]), and parenteral antiplatelets (-391,880 EU [95% CI, -535,420 to -248,330]). During the pandemic, the monthly volume of oral anticoagulants, parenteral anticoagulants, and parenteral antiplatelets grew significantly more than in the prepandemic period. This growth was primarily seen in volumes of apixaban, argatroban, enoxaparin, heparin, eptifibatide, and tirofiban. Apixaban and heparin volumes continued a prepandemic uptrend, while argatroban and eptifibatide volumes reversed trend. CONCLUSION: Rapid changes in anticoagulant and antiplatelet volume at US hospitals during the COVID-19 pandemic highlight the need for institutional protocols to manage fluctuating medication volume demands.

Changes in the availability of medications for opioid use disorder in prisons and jails in the United States during the COVID-19 pandemic.

BACKGROUND: During the COVID-19 pandemic, federal agencies relaxed buprenorphine prescribing restrictions including for incarcerated individuals. The impact of COVID-19 on the supply of MOUD in U.S. prisons and jails is not known. METHODS: We used cross-sectional national monthly data from the IQVIA National Sales Perspective (NSP) for the total volume of medicines supplied to city, county and state prisons and jails and other types of institutional facilities in the U.S. We measured the total monthly supply (or volume) as extended units (EUs) for MOUDs overall and by type. We used interrupted time series analysis to evaluate changes in monthly volume of MOUDs in prisons and jails and other types of facilities (hospitals, clinics and long-term care) before (January 2018-February 2020) and during the COVID-19 (March 2020-October 2020) pandemic. RESULTS: The availability of MOUD in jails and prisons increased by 471.3% between January 2018 (52,784 EU) and October 2020 (333,226 EU). This increase was largely driven by increased volume of buprenorphine/naloxone and was not observed in other institutional facilities, including hospitals, clinics and long-term care, and. Specifically, the mean monthly volume of buprenorphine/naloxone at prisons/jails increased every month before the pandemic by 1860 EU (95% CI, 1110-2360). In March 2020, the mean volume of buprenorphine/naloxone increased by 81,930 EU (95% CI, 59,040-104,820) per month, followed by a significant increase of 24,010 EU (95% CI 19,530-28,490) per month during the pandemic vs before the pandemic. CONCLUSION: These findings may indicate increased availability of buprenorphine/naloxone, a safe and effective MOUD, in prisons and jails since the start of the COVID-19 pandemic in the U.S. despite previous barriers in its use.

Global, regional and national trends in statin utilisation in high-income and low/middle-income countries, 2015-2020.

OBJECTIVE: Prior studies have reported inequitable global access to essential medicines for cardiovascular disease (CVD) prevention, especially statins. Here we examine recent trends and disparities in statin utilisation at the income group, regional and country levels. DESIGN: Ecological study. Pharmaceutical sales data were used to examine statin utilisation in high-income counties (HICs) and low/middle-income countries (LMICs) from 2015 to 2020. Population estimates were obtained from the Global Burden of Disease. Fixed-effects panel regression analysis was used to examine associations between statin utilisation and country-level factors. SETTING: Global, including 41 HICs and 50 LMICs. PARTICIPANTS: Population older than 40 years of age. PRIMARY AND SECONDARY OUTCOME MEASURES: Statin utilisation was measured using defined daily doses (DDDs) per 1000 population ≥40 years per day (TPD). RESULTS: Globally, statin utilisation increased 24.7% from 54.7 DDDs/TPD in 2015 to 68.3 DDDs/TPD in 2020. However, regional and income group disparities persisted during this period. In 2020, statin utilisation was more than six times higher in HICs than LMICs (192.4 vs 28.4 DDDs/TPD, p<0.01). Substantial disparities were also observed between LMICs, ranging from 3.1 DDDs/TPD in West African nations to 225.0 DDDs/TPD in Lebanon in 2020. While statin utilisation increased in most LMICs between 2015 and 2020, several experienced declines in utilisation, most notably Venezuela (-85.1%, from 92.3 to 14.0 DDDs/TPD). In LMICs, every $100 increase in per capita health spending was associated with a 17% increase in statin utilisation, while every 10% increase in out-of-pocket health spending was associated with a 11% decline (both p<0.05). CONCLUSIONS: Despite global increases in statin utilisation, there are substantial regional and country-level disparities between HICs and LMICs. To address global CVD disparities, policymakers should promote increased and equitable access to statins in LMICs.

Cancer care spending and use by site of provider-administered chemotherapy in Medicare.

OBJECTIVES: To compare cancer care spending and utilization by site of provider-administered chemotherapy in Medicare. STUDY DESIGN: A retrospective analysis using 2010-2013 Medicare claims. METHODS: The study population was a random sample of Medicare fee-for-service beneficiaries with cancer who initiated provider-administered chemotherapy in a hospital outpatient department (HOPD) or physician office (PO). We assessed the following outcomes during the 6-month follow-up period: (1) spending on cancer-related outpatient services excluding chemotherapy, (2) spending on cancer-related inpatient services, (3) utilization of select cancer-related outpatient services (evaluation and management, commonly used expensive billing codes, and radiation therapy sessions), and (4) the number of cancer-related hospitalizations. We used regression analyses to adjust for patient health risk factors and market characteristics. RESULTS: During the 6-month follow-up period, risk-adjusted spending on nonchemotherapy outpatient services was slightly lower among patients receiving chemotherapy in HOPDs than in POs ($12,183 [95% CI, $12,008-$12,358] vs $12,444 [95% CI, $12,313-$12,575]; P <.05). Risk-adjusted cancer-related inpatient spending was higher in the HOPD group than in the PO group ($3996 [95% CI, $3837-$4156] vs $3168 [95% CI, $3067-$3268]; P <.01). The HOPD group had fewer visits in all select outpatient services but had a higher number of hospitalizations than the PO group. CONCLUSIONS: Differences in cancer care spending by site of chemotherapy (HOPDs vs POs) vary by service type. Those differences are partially driven by utilization differences. As the site of chemotherapy shifts from POs to HOPDs, spending and utilization patterns in both settings need to be monitored.
