Identification of patients on chronic prescription opioids at risk for opioid use disorder using pharmacy claims data.

Using pharmacy claims data from a single commercial health plan to identify opportunities for opioid use disorder (OUD) focused screening and interventions communicated via targeted prescriber messaging. Participants included members ≥18 years using more than 90 morphine milligram equivalents (MMED) daily based on all opioid claims, had >1 paid claim for an opioid product, and had ≥90 days of total opioid therapy. Members were excluded with ≥1 claims for an oral chemotherapy agent (except methotrexate). Intervention was completed with a secure communication to the primary outpatient opioid prescriber that included resources for diagnosis, treatment, and best practices for opioid prescribing. The main outcome measure was any documented change to opioid use following the intervention. Seven hundred forty-five members were identified; a subset (n = 20) was further assessed, and all had identified OUD risk factors; providers were subsequently sent a communication. Sixteen providers acknowledged receipt and 11 patients (55%) had at least one documented intervention following communication receipt. Provision of targeted, evidence-based recommendations to providers for patients identified to be at risk of OUD from pharmacy claims data can result in increased recognition and intervention. Future efforts to explore feasibility of provider education detailing efforts and continued evaluation of efficacy are needed.

6550 National Statin Prescription Trends in Patients With Breast Cancer and Diabetes for Primary Cardiovascular Disease Prevention

Abstract Disclosure: A.B. Yang: None. G. Mhango: None. C. Kong: None. J.J. Lin: None. J.P. Wisnivesky: Consulting Fee; Self; Sanofi, Banook, PPD. Grant Recipient; Self; Sanofi, Regeneron Pharmaceuticals, Axella, Arnold Consultants. A. Leiter: None. Background: Cardiovascular disease (CVD) is the leading cause of death in older early-stage breast cancer (BC) survivors. Due to cardiotoxic BC treatments such as chemotherapy and radiation, patients with BC and diabetes (DM) are at increased risk of CVD. In patients with BC and DM, statins decrease CVD mortality. Since 2013, many clinical guidelines broadened statin indications for primary CVD prevention in patients with DM, making >85% of patients eligible. Little is known about statin prescription (Rx) patterns in older BC survivors with DM, a group at high risk of CVD. Hypothesis: We hypothesized that statin Rxs increased over time, but were less likely in BC survivors with more advanced locoregional BC and lower comorbidity burden. Methods: A population-based, retrospective cohort study was conducted using Surveillance, Epidemiology and End Results (SEER) cancer registry data linked to Medicare claims. We identified women with preexisting DM who were diagnosed with stage 0-III primary BC between 2008-17. We excluded patients with prior CVD who died <1 year after BC diagnosis. Statin Rx (atorvastatin, pravastatin, rosuvastatin, simvastatin, fluvastatin, lovastatin) was defined as ≥1 statin pharmacy claim <1 year after BC diagnosis. Comorbidity burden was assessed with a modified Charlson Comorbidity Index (CCI). We compared patient demographic and clinical characteristics by statin Rx status using the chi-square test. Using a multivariate logistic regression adjusting for age, race, CCI, BC stage, and diagnosis year, independent predictors of statin Rx were identified. Results: Of 8,423 BC patients with pre-existing DM, 5,698 (68%) had a statin Rx. Statin Rx increased over time (BC diagnosis year 2008-10: 66%, 2011-13: 66%, 2014-15: 69%, 2016-17: 70%; p=0.01) and differed by age (66-69: 66%, 70-74: 70%, 75-79: 69%, ≥80: 65%; p<0.01) and race (White: 68%, Black: 62%, Latinx: 66%, Other: 72%; p<0.01). Statin Rx did not differ by comorbidity burden (CCI 0: 68%, 1-2: 67%, ≥3: 67%; p=0.87) and declined with higher BC stage (0: 73%, I: 70%, II: 65%, III: 63%; p<0.01). In adjusted analyses, more recent BC diagnosis (2016-17 vs. 2008-10: odds ratio [OR]: 1.19, 95% confidence interval [CI]: 1.04-1.38), age group (70-74 vs. 66-69: OR: 1.24, 95% CI: 1.09-1.41), race (Black vs. White: OR 0.77, 95% CI: 0.66-0.89) and higher BC stages (II vs. 0: OR: 0.76, 95% CI: 0.58-1.00; III vs. 0: OR: 0.72, 95% CI: 0.54-0.97) remained predictors of statin Rx. Conclusions: In a nationally representative cohort analysis of older early-stage BC patients, statin Rx increased between 2008-17 and varied by age, race, and BC stage. Elucidating gaps in statin Rx can potentially improve guideline-concordant Rx in a group at high risk for CVD and reduce disparities. Presentation: 6/2/2024

7459 Predictors of a Second Fracture in Men With Osteoporosis-related Fractures

Abstract Disclosure: R.H. Lee: None. Y. Wang: Employee; Self; Radius Health, Inc. S.A. Williams: Employee; Self; Star Biopharma, LLC. N. Pyrih: Employee; Self; Cobbs Creek Healthcare. B.H. Mitlak: Employee; Self; Radius Health, Inc. J.R. Curtis: Consulting Fee; Self; Amgen Inc, Eli Lilly & Company, Radius Health, Inc, UCB. Grant Recipient; Self; Amgen Inc, Eli Lilly & Company, Radius Health, Inc, UCB. Background: Management of osteoporosis (OP)-related fractures in men is suboptimal. Real-world evidence suggests that, after men sustain a first fracture, they experience a higher risk for subsequent fracture and greater mortality compared to women. There is limited knowledge regarding absolute risk and predictors of second fractures in men and fracture risk assessment tools may be less accurate in men (Vilaca et al 2022). The objective of this study was to develop a model to identify risk factors for a second fracture in men in the year following an initial fracture. Methods: Anonymized patient-level medical and pharmacy claims data from Symphony Health PatientSource® were used. The study criteria included males ≥40 years with a case-qualifying OP-related fracture between January 1, 2017 to May 31, 2021 based on a claims-based validated algorithm (Wright et al 2019). Logistic regression models with a binary outcome of a second fracture versus no second fracture within one year of index fracture were created to predict second fracture occurrence. The study built upon a previous model (Williams et al 2021) developed for OP-related fractures for both men and women incorporating additional variables relevant to men based on the current literature. A separate model to identify risk factors for a secondary nonvertebral fracture (NVF) in men was also developed. Results: Of 956,828 men identified with an index fracture (677,047 commercial; 279,781 Medicare Advantage), 13% (126,106) experienced a second fracture within 1 year following the index fracture. More than two thirds of secondary fractures were NVFs. Multivariable logistic regression showed that patients with an index fracture at the spine (OR [95% CI] 1.71 [1.68, 1.74]) or hip (OR [95% CI] 1.79 [1.75, 1.82]) were the most likely to have a second fracture within a year of index fracture. An index clinical spine fracture was not associated with an increased risk of secondary NVFs. Nonfracture spinal cord injury was included among the predictors with the greatest magnitude of estimate for NVF (OR [95% CI] 1.21 [1.08, 1.36]). In addition to fracture history, advanced age, history of falls, use of medications that increase fall risk, OP diagnosis, treatment with OP medication, low body weight, and excessive alcohol use were significant and the numerically largest predictors for a second fracture. Type 2 diabetes, but not GLP-1 use, also increased risk of secondary fracture. Variables negatively associated with future fractures included treatment history with alpha blockers (beta blockers in the Medicare cohort) and diuretics. Conclusion: Predictors of fracture in men were overall consistent with the literature (and risk factors identified in the FRAX risk calculator). Regardless of gender, recent fracture is always the highest risk factor for a secondary fracture. Presentation: 6/3/2024

Age and racial and ethnic disparities in filled buprenorphine prescriptions post-emergency department visit in Nevada.

We described age, gender, race, and ethnicity associations with filling buprenorphine prescriptions post-emergency department (post-ED) visits. We analyzed 1.5 years (July 1, 2020-December 31, 2021) of encounter-level Medicaid ED and retail pharmacy claims data obtained from the Nevada Department of Health and Human Services. We studied ED patients with an opioid use disorder (OUD) diagnosis who did not fill a prescription for OUD medications within 6 months before the ED encounter. Using logistic regression, we modeled the associations between the patient's demographic characteristics and the outcome, filling a buprenorphine prescription at a community pharmacy within 14 or 30 days of the ED encounter. Among 2781 ED visits, representing 2094 patients, the median age was 39 years, 54% were male, 18.5% were Black, 11.7% were Hispanic, and 62.3% were White. Only 4% of the ED visits were followed by a filled buprenorphine prescription. Increasing age (14-day window: adjusted odds ratio (aOR)=0.965, 95% confidence interval [CI]: 0.948-0.983) and being a Black patient (14-day window: aOR: 0.114, 95% CI 0.036-0.361) were both associated with lower odds of filled buprenorphine prescriptions. These results were similar within 30 days of an ED visit. Initiation of buprenorphine following an ED visit remains low among Nevadan Medicaid patients and is less likely with increasing age and among Black patients, despite strong evidence supporting its use. Overburdened EDs, lack of attention from managers, and substance use stigma are among possible explanations. When ED clinicians do write buprenorphine prescriptions, peer recovery support could increase the fill rates.

Increased Identification of Vaccines for Vaccine Safety Surveillance Through Linkage With the Minnesota Immunization Information Connection as of December 31, 2023.

The HealthPartners' Vaccine Safety Datalink (VSD) team maintains standardized files of vaccines from medical and pharmacy claims and electronic health records (established data sources) for safety surveillance. Since 2021, for selected vaccines, data from the Minnesota Immunization Information Connection (MIIC), Minnesota's immunization information system, have been added to the HealthPartners' VSD files. We examined how MIIC data have enhanced the identification of novel and routine vaccines. We describe the approach to incorporating MIIC data. We determined and compared the number and proportion of vaccines identified from established data sources with the additional capture of vaccine data identified from MIIC, in which age group and period of observation varied by vaccine. As of December 31, 2023, of 1 099 411 people in the HealthPartners' VSD cohort, 1 001 400 people (91%) were linked with an MIIC record. Across all data sources, for the full cohort, >2.7 million COVID-19 vaccine doses were recorded since 2020, >4000 mpox vaccine doses since 2022, >7.3 million influenza vaccine doses since 2004, >600 000 human papillomavirus (HPV) vaccine doses since 2006, and >1.1 million diphtheria and tetanus toxoids and acellular pertussis (DTaP) vaccine doses since 2004. For COVID-19 vaccines, about 30% of vaccine doses were exclusively captured from MIIC, with the remaining 70% from established data sources. For the mpox vaccine, about 42% were exclusively from MIIC. For influenza, HPV, and DTaP vaccines, about 20%, 14%, and 17%, respectively, were exclusively identified from MIIC. Incorporation of data from state immunization information systems into existing vaccine data files can enhance monitoring on the safety of novel vaccines administered outside traditional health care settings and can enhance data quality for routine childhood and adult vaccines.

The impact of cancer-related diarrhea on changes in cancer therapy.

The impact of cancer-related diarrhea (CRD) on changes in cancer therapy remains poorly characterized despite its prevalence. We performed a longitudinal observational study using IQVIA PharMetrics Plus claims data. Patients included adults with CRD identified by diagnosis codes or pharmacy claims and compared their outcomes to matched (1:1) patients without CRD. Treatment parameters (discontinuation, persistence, augmentation, dose titration, adherence) were evaluated and stratified for the first cancer therapy (chemotherapy vs. targeted therapy vs. both). A multivariate Cox proportional hazards model was used to estimate the difference in risk of each treatment parameter between cohorts, adjusting for cancer type, therapy, and comorbidities. We identified 104,135 matched pairs of patients with solid (n = 94,411) or hematologic cancers (n = 9,724) receiving chemotherapy (n = 47,220), targeted therapy (n = 2,427), or both (n = 5,313). Patients with CRD discontinued therapy more frequently than those without CRD (chemotherapy [81.5% vs. 62.3%], targeted therapy [69.2% vs. 64.3%], both [96.0% vs. 85.5%], p < 0.0001). The overall proportion of discontinuation was higher (82.4% vs. 64.6%, p < 0.0001), including a higher risk of discontinuation (HR = 1.40, p < 0.001) for patients with CRD. The mean time to discontinuation (59.6 ± 54.1 vs. 68.3 ± 76.6days), switch (72.0 ± 48.6 vs. 96.9 ± 84.0days), persistence (95.1 ± 98.1 vs. 154.3 ± 142.7days), and adherence (25.5% ± 37.2 vs. 47.9 ± 41%) were all lower (p < 0.0001) among patients with CRD. Patients who develop CRD undergo significant and clinically impactful index treatment discontinuation, treatment switching, and have lower adherence and persistence of anticancer therapy compared to patients without CRD. Strategies to control CRD to optimize cancer therapy are urgently needed.

Statin use and risks of breast cancer recurrence and mortality.

Preclinical evidence suggests improved breast cancer survival associated with statin use, but findings from observational studies are conflicting and remain inconclusive. The objective of this study was to assess the association between statin use after cancer diagnosis and cancer outcomes among breast cancer patients. In this retrospective cohort study, 38,858 women aged ≥66 years who were diagnosed with localized and regional stage breast cancer from 2008 through 2017 were identified from the linked Surveillance, Epidemiology, and End Results Medicare database. Statin use was ascertained from Medicare Part D pharmacy claims data. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between post-diagnosis statin use and risks of breast cancer recurrence and breast cancer-specific mortality. Over a median follow-up of 2.9 years for recurrence and 3.7 years for mortality, 1446 women experienced a recurrence, and 2215 died from breast cancer. The mean duration of post-diagnosis statin use was 2.2 years. Statin use post-diagnosis was not associated with recurrence risk (HR, 1.05; 95% CI, 0.91-1.21), but was associated with a reduced risk of cancer-specific mortality (HR, 0.85; 95% CI, 0.75-0.96). The reduction was more pronounced in women with hormone receptor-positive/human epidermal growth factor receptor 2-negative breast cancer (HR, 0.71; 95% CI, 0.57-0.88). These findings suggest that post-diagnosis statin use is associated with improved cancer-specific survival in women with breast cancer and should be confirmed in randomized trials of statin therapy in breast cancer patients.

Manufacturer-sponsored drug coupon use and drug-switching behavior among patients with type 2 diabetes.

Patients often use manufacturer-sponsored coupons to reduce their out-of-pocket spending. However, little is known whether coupon use is associated with medication-switching behaviors. To examine if using a manufacturer-sponsored coupon to initiate a medication is associated with patterns of medication-switching behaviors among patients with type 2 diabetes. Using IQVIA's retail pharmacy claims data from October 2017 to September 2019, we analyzed commercially insured patients with type 2 diabetes who had newly started taking the following noninsulin diabetes drugs: generic metformin (nearly no coupon use), Sodium-glucose Cotransporter-2 (SGLT2) Inhibitors (SGLT2, high coupon use), and dipeptidyl peptidase IV inhibitors (DPP-IV inhibitors, moderate coupon use). We assessed if drug-switching behaviors, defined as no switching, switching to a same-class drug, or switching to a drug in a different class, differed among patients who did and did not use coupons to initiate treatments. We performed multinomial logistic regression to estimate the probability of each switching type associated with patients' initial coupon use. Among 9,781 patients in our sample, 83.7% of them initiated treatments with metformin, 8.2% with SGLT2, and 8.1% with DPP-IV inhibitors. The overall switching rate was the lowest for generic metformin (40%) than brand-name drugs (56%-57%). Among the brand-name drug users, patients who used a coupon to initiate these drugs were less likely to switch to any drug compared with patients without coupon use (SGLT2 = -18% [95% CI = -24% to -13%]; DPP-IV inhibitors = -9% [-16% to -2%]). These patients were also less likely to switch to drugs in other competing classes (SGLT2 = -16% [95% CI = -22% to -10%]; DPP-IV inhibitors = -9% [-16% to -2%]). Patients who started their treatment with generic metformin had the lowest rate of drug switching. Using coupons to initiate brand-name drugs in classes with prevalent coupons was associated with reduced medication switching to other class drugs.

Adult Pharmacy Costs and Characteristics of Very High-Cost Prescription Drug Users in the United States, 2018–2022

Objective: This study sought to identify: (1) the demographic and clinical characteristics of very high-cost users (defined as patients with pharmaceutical expenditures that were equal to or greater than the 99th percentile), (2) whether or not these characteristics changed over time, (3) sociodemographic and clinical correlates of being very high-cost users, (4) the average pharmaceutical costs of very-high cost users, and (5) the therapeutic classes and medications that contributed to these high costs Background: There are growing public concerns about rising drug costs, in part due to increased availability, greater effectiveness, and market considerations. There is a concentrated portion of patients that accounts for a disproportionately large portion of pharmaceutical expenditures. Methods: A large serial cross-sectional study was conducted with De-identified, member-level pharmacy claims (n = 65,739,791) from a large, national pharmacy benefits manager from January 1, 2018 to December 31, 2022. The main outcome and measures were 2018–2022 pharmaceutical expenditures; amounts were adjusted for inflation to reflect 2022-dollar values. Results: Across the study period, the odds of being classified as a very high-cost user were 1.31 times as high for those 45–64 years old compared with those 18–44 years old (reference category); the odds were 1.42 times as high for males compared with females; 1.13 times as high before those identifying as non-Hispanic Black compared with non-Hispanic white; 1.11 times as high for those enrolled in a health care exchange plan compared with a commercial plan. In addition, very high-cost users lived in areas with higher social needs. Human immunodeficiency virus, inflammatory conditions, multiple sclerosis, and cancer accounted for the largest share of costs among this group. Conclusions: This study identified the unique characteristics of very high-cost pharmaceutical users and identified the top conditions and prescription drugs that drove high pharmaceutical expenditures among this population. These findings are essential to understanding rising pharmaceutical costs in the United States and can help identify the issues and solutions of specific cost drivers within our health care policies.

Differences in Healthcare Resource Use and Cost by Pharmacotherapy Among Patients with Symptomatic Obstructive Hypertrophic Cardiomyopathy: Real-World Analysis of Claims Data.

For symptomatic obstructive hypertrophic cardiomyopathy (oHCM), limited evidence exists on healthcare resource utilization (HRU) and cost for patients with symptomatic oHCM by treatment categories. We evaluated whether HRU and costs vary by initial treatment in symptomatic oHCM. This is a retrospective study of medical and pharmacy claims from 2016 to 2021 to identify (per International Classification of Disease Tenth Revision diagnosis codes) adult patients in the USA with symptomatic oHCM. Patients included in the study cohort were required to be treatment naïve (≥ 12 months' activity before first treatment) and symptomatic (fatigue, chest pain, syncope, dyspnea, heart failure, or palpitations within 3 months of index date). Patients were grouped by first index treatment [beta blocker (BB), calcium channel blockers (CCB), disopyramide, combination therapy], and HRU and costs [per person per year (PPPY), in USD] by initial treatment were reported. Among 7334 patients with symptomatic oHCM, initial treatment included BB (65.8%), CCB (21.1%), disopyramide (1.2%), or BB + CCB (11.9%). Overall, 87.2% were prescribed monotherapy. Outpatient visits were the main driver of all-cause HRU (mean 11.5 PPPY), and varied by initial treatment (BB: 11.0, CCB: 10.5, disopyramide: 7.2, combination therapy: 12.1). All-cause urgent care visits were more frequent than inpatient visits (means: 5.4 and 0.83 PPPY, respectively). All-cause incurred costs were $46,628 PPPY overall and varied by treatment (BB: $47,029, CCB: $42,124, disopyramide: $27,007, combination therapy: $54,024). In this large, US-based cohort of patients with symptomatic oHCM, initial therapy was most commonly BB and CCB monotherapy. Costs and HRU were high for most patients, but greater for those treated initially with combination therapy.

Clinician Specialty and HIV PrEP Prescription Reversals and Abandonments

Clinicians are a key component of preexposure prophylaxis (PrEP) care. Yet, no prior studies have quantitatively investigated how PrEP adherence differs by clinician specialty. To understand the association between prescribing clinician specialty and patients not picking up (reversal/abandonment) their initial PrEP prescription. This cross-sectional study of patients who were 18 years or older used pharmacy claims data from 2015 to 2019 on new insurer-approved PrEP prescriptions that were matched with clinician data from the US National Plan and Provider Enumeration System. Data were analyzed from January to May 2022. Clinician specialties included primary care practitioners (PCPs), infectious disease (ID), or other specialties. Reversal was defined as a patient not picking up their insurer-approved initial PrEP prescription. Abandonment was defined as a patient who reversed and still did not pick their prescription within 365 days. Of the 37 003 patients, 4439 (12%) were female and 32 564 (88%) were male, and 77% were aged 25 to 54 years. A total of 24 604 (67%) received prescriptions from PCPs, 3571 (10%) from ID specialists, and 8828 (24%) from other specialty clinicians. The prevalence of reversals for patients of PCPs, ID specialists, and other specialty clinicians was 18%, 18%, and 25%, respectively, and for abandonments was 12%, 12%, and 20%, respectively. After adjusting for confounding, logistic regression models showed that, compared with patients who were prescribed PrEP by a PCP, patients prescribed PrEP by ID specialists had 10% lower odds of reversals (odds ratio [OR], 0.90; 95% CI, 0.81-0.99) and 12% lower odds of abandonment (OR, 0.88; 95% CI, 0.78-0.98), while patients prescribed by other clinicians had 33% higher odds of reversals (OR, 1.33; 95% CI, 1.25-1.41) and 54% higher odds of abandonment (OR, 1.54; 95% CI, 1.44-1.65). The results of this cross-sectional study suggest that PCPs do most of the new PrEP prescribing and are a critical entry point for patients. PrEP adherence differs by clinician specialties, likely due to the populations served by them. Future studies to test interventions that provide adherence support and education are needed.

Cancer information and population health resource: a resource for catchment area data and cancer outcomes research.

The University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center has developed a novel data resource, the Cancer Information and Population Health Resource (CIPHR), for conducting catchment area evaluation and cancer population health research that links the North Carolina Central Cancer Registry (NCCCR) to medical and pharmacy claims data from Medicare, Medicaid, and private plans operating within North Carolina. This study's aim was to describe the CIPHR data and provide examples of potential cohorts available in those data. We present the underlying populations included in the NCCCR and claims data before linkage and demonstrate estimated sample sizes when these data are linked and commonly used insurance enrollment criteria are applied. Data for the years 2003-2020 are present in CIPHR and include 947 977 cancer cases from the NCCCR and 21.6 million enrollees in public and private health insurance (cancer and noncancer cases). When limited to first or only cancers (n = 672 377), 86% could be linked to insurance enrollment for at least 1 month during 2003-2020 (n = 582 638), with 62% of individuals linking to enrollment during the month of cancer diagnosis. Among all registry cancer cases, 47% (n = 317 898) had continuous insurance enrollment for at least 12 months before and after cancer diagnosis. CIPHR illustrates the utility of establishing and maintaining a statewide, comprehensive cancer population health database. This resource serves to characterize the cancer center catchment area and aids in tracking cancer outcomes and trends in care delivery as well as identifying disparities that require intervention and policy focus.

Recent trends in psychotropic medication use in children and adolescents in Ireland.

In response to concerns regarding overprescribing of psychotropic medication in children/adolescents, this study examined trends in psychotropic medication use in Ireland by age group and gender. A retrospective, repeated, cross-sectional study of the Irish pharmacy claims database was conducted. Yearly prevalence of children/adolescents receiving dispensed psychotropic medications was analysed from January 2017 to December 2021 and compared across years, age groups (5-15 years, and stratified as 5-11 and 12-15 years) and gender. Yearly prevalence was defined as the mean number of patients in receipt of medication per month per 1000 eligible population during a given calendar year. Negative binomial regression was used to examine the association of year, age group and gender on prevalence. Prevalence ratios (PRs) per year (average change in prevalence between each year) were presented with 95% confidence intervals (CIs). The prevalence of included psychotropic medications dispensed in the 5-15 years group increased from 6.41 (95% CI: 6.22, 6.59) in 2017 to 8.46 (95% CI: 8.26, 8.68) in 2021 per 1000 eligible population (32% increase). The PR per year (adjusting for age category and gender) was 1.07 (95% CI: 1.035, 1.107; p < 0.001). An increasing trend over time was also observed for all individual drug classes. These findings suggest increased use of psychotropic medication in children/adolescents from 2017 to 2021. However, despite increased prevalence over time, comparison with the literature shows that psychotropic medication use in Ireland remains lower than international comparators.

Racial disparities in treatment patterns, healthcare resource use, and outcomes in patients with pulmonary arterial hypertension in the United States

Objective This retrospective study using claims data compared demographics, clinical characteristics, treatment patterns, healthcare resource utilization, and clinical outcomes in Black and White patients with pulmonary arterial hypertension (PAH) in the United States. Methods Patients (aged ≥18 years) had ≥1 pharmacy claim for PAH medication, ≥6 months’ continuous healthcare plan enrollment, ≥1 inpatient/outpatient medical claim with a pulmonary hypertension diagnosis ≤6 months before first PAH medication, and race recorded. Results This analysis included 836 Black and 2896 White patients. Black patients were younger, with lower levels of education and annual household income, and higher comorbidity scores versus White patients. Only ∼14% of Black and White patients received index combination therapy. Lower adherence to index treatment was observed in Black patients. Although adjusted regression analysis in the overall population showed no differences in outcomes between groups, Black patients <65 years were 36% less likely to receive index combination therapy (odds ratio [OR] 0.64; 95% confidence interval [CI] 0.41–0.99), and 46% less likely to adhere to index treatment (OR 0.54; 95% CI 0.33–0.90). Other disparities included 24% higher all-cause health care resource utilization, 75% higher all-cause costs, and higher risk of clinical composite outcome. Social determinants of health (education, income, health insurance plan) partially mediated these race effects. Conclusions Differences in demographics, clinical characteristics, and treatment patterns between Black and White patients with PAH were observed. Disparities between Black and White patients <65 years were only partially mediated through social determinants of health variables, suggesting other factors may be involved.

Treatment Patterns and Resource Use After Osimertinib Discontinuation in Patients with EGFR + Metastatic NSCLC.

Current treatment guidelines for patients with epidermal growth factor receptor (EGFR)-mutated metastatic non-small cell lung cancer (mNSCLC)recommend EGFR tyrosine kinase inhibitors (TKIs) as the standard of care for first-line treatment, with third-generation osimertinib the preferred choice. However, most patients develop resistance to targeted therapy, and subsequent systemic chemotherapy is recommended. The aim of this study was to characterize the subsequent line of therapy (LOT) following osimertinib in patients with EGFR-mNSCLC. Medical and pharmacy claims of adults who initiated a subsequent LOT (index) after initial osimertinib discontinuation between November 2015 and September 2019 were analyzed retrospectively. A total of 135 patients met the inclusion criteria. After metastatic diagnosis, 22.2% and 49.6% of patients were treated with osimertinib in the first and second line, respectively. After osimertinib discontinuation, most patients were treated with a platinum-based chemotherapy regimen (57%), of which 40.3% included immuno-oncology therapy. Reuse or continuation of EGFR TKIs was also common (24%). Overall, the median time to treatment discontinuation for the index LOT was 2.4months. Proportions of patients with ≥ 1 inpatient or emergency department visit were 31.9% and 35.6%, respectively. The duration of the LOT following osimertinib was short and associated with tolerability issues underscoring a high unmet need for new therapies to address EGFR TKI resistance.

Brief communication: temporal trends of chronic diseases medications prescriptions among HIV-infected patients in Belgium: a 4-year population-based study using pharmacy claims data

The Objective of this study was to examine change over time of prevalence of chronic diseases medications (CDM) prescriptions among People living with HIV (PLWH) in Belgium, using Pharmanet database from 2018 to 2021. We identified 13,570, 14,175, 14,588 and 14,813 PLWH in 2018, 2019, 2020 and 2021, respectively. Prescriptions of cardiovascular diseases (CVD) medications (31.7–37.2%) and antidiabetics (7.4–9.0%), increased significantly (p for trend < 0.001 for all), while the prescription of neurological and mental disorders medications (18.0–19.3%) remained stable (p for trend = 0.11) and the prescription of chronic respiratory diseases (CRD) medications decreased from 12.2 to 10.6% (p for trend < 0.001), between 2018 and 2021. It is imperative to ensure that these medications are used appropriately.

A Randomized Controlled Trial Testing the Effects of a Social Needs Navigation Intervention on Health Outcomes and Healthcare Utilization among Medicaid Members with Type 2 Diabetes.

Health systems are increasingly assessing and addressing social needs with referrals to community resources. The objective of this randomized controlled trial was to randomize adult Medicaid members with type 2 diabetes to receive usual care (n = 239) or social needs navigation (n = 234) for 6 months and compare HbA1c (primary outcome), quality of life (secondary outcome), and other exploratory outcomes with t-tests and mixed-effects regression. Eligible participants had an HbA1c test in claims in the past 120 days and reported 1+ social needs. Data were collected from November 2019 to July 2023. Surveys were completed at baseline and at 3-, 6-, and 12-month follow-up. Health plan data included care management records and medical and pharmacy claims. The sample was from Louisiana, USA, M = 51.6 (SD = 9.5) years old, 76.1% female, 66.5% Black, 29.4% White, and 3.0% Hispanic. By design, more navigation (91.5%) vs. usual care (6.7%) participants had a care plan. Social needs persisted for both groups. No group differences in HbA1c tests and values were observed, though the large amount of missing HbA1c lab values reduced statistical power. No group differences were observed for other outcomes. Proactively eliciting and attempting to provide referrals and resources for social needs did not demonstrate significant health benefits or decrease healthcare utilization in this sample.

Prevalence of Tendon Rupture and Tendinopathies Among Patients with Atherosclerotic Cardiovascular Disease Derived From United States Administrative Claims Data.

The prevalence of tendon rupture and tendinopathies (TRT) has not been determined in a large population of patients with atherosclerotic cardiovascular disease (ASCVD). We investigated TRT prevalence among patients with ASCVD and in the general population, using data from the Symphony Health Integrated Dataverse, a large US medical and pharmacy claims database. This retrospective, observational study included patients aged ≥ 19years from the claims database during the identification period (January 2019 to December 2020) and 12months of continuous enrollment. The primary outcome was evidence of TRT in the 12months following the index date (first ASCVD diagnosis in the ASCVD cohort; first claim in the claims database in the overall population). Diagnostic codes (ICD-10 and/or CPT) were used to define ASCVD and TRT diagnosis. The ASCVD cohort and overall population included 5,589,273 and 61,715,843 patients, respectively. In the ASCVD cohort, use of medications with a potential or known association with TRT was identified in 67.9% (statins), 17.7% (corticosteroids), and 16.7% (fluoroquinolones) of patients. Bempedoic acid use was reported in 1556 (< 0.1%) patients. TRT prevalence during 12-month follow-up was 3.4% (ASCVD cohort) and 1.9% (overall population). Among patients with ASCVD, 83.5% experienced TRT in only one region of the body. Factors most associated with TRT in the ASCVD cohort were increasing age, most notably in those aged 45-‍64 years (odds ratio [OR] 2.19; 95% confidence interval [CI] 2.07-2.32), obesity (OR 1.51; 95% CI 1.50-1.53), and rheumatoid arthritis (OR 1.47; 95% CI 1.45-1.79). Use of statins or bempedoic acid was not associated with increased TRT risk. Patients with ASCVD may have greater risk of TRT than the general population, which may be driven by an increased prevalence of comorbidities and use of medications with a potential or known association with TRT.

Impact of COVID-19 on work loss in the United States- A retrospective database analysis

Objectives This study investigates the utilization of work absence benefits among United States (US) employees diagnosed with COVID-19, examining frequency, duration, cost, and types of work loss benefits used. Methods This retrospective analysis of the Workpartners Research Reference Database (RRDb) included employees eligible for short- and long-term disability (STD and LTD employer-sponsored benefits, respectively), and other paid work absence benefits from 2018 to 2022. Workpartners RRDb includes over 3.5 million employees from over 500 self-insured employers across the US. Employees were identified by codes from adjudicated medical and disability claims for COVID-19 (2020–2022) and influenza, as well as prescription claims for COVID-19 treatments. Associated payments were quantified for each absence reason. Results Approximately 1 million employees were eligible for employer-sponsored paid leave benefits between January 2018 and December 2022. The mean age was 37 years (22% >50 years), and 49.4% were females. COVID-19 was the 2nd most common reason for an STD claim (6.9% of all STD claims) and 13th for an LTD claim (1.7% of all LTD claims) from 2020–2022. The mean duration for COVID-19 STD claims was 24 days (N = 3,731, mean claim=$3,477) versus 10 days for influenza (N = 283, mean claim=$1,721). The mean duration for an LTD claim for COVID-19 was 153 days (N = 11, mean claim=$19,254). Only 21.5% of employees with STD claims in the COVID-19 cohort had prior COVID-19-associated medical or pharmacy claims; over half (range 53%–61%) had documented high risk factors for severe COVID-19. Conclusion COVID-19 and influenza have the potential to cause work loss in otherwise healthy employees. In this analysis, COVID-19 was the second most frequent reason for an STD claim at the start of the pandemic and remained high (ranked 5th) in 2022. These results highlight the impact of COVID-19 on work loss beyond the acute phase. Comprehensively evaluating work loss implications may help employers prioritize strategies, such as vaccinations and timely treatments, to mitigate the impact of COVID-19 on employees and their companies.

Long-Term HIV Pre-Exposure Prophylaxis Persistence and Reinitiation in Connecticut from 2012 to 2018.

HIV pre-exposure prophylaxis (PrEP) is a highly effective biomedical prevention for HIV infections. PrEP persistence is critical to achieving optimal protection against HIV infection. However, little is known about PrEP persistence in the United States. This study utilized the Connecticut All-Payer Claims Database (APCD) to identify PrEP persistence among patients who filled their PrEP prescriptions in the state. The authors identified 1,576 PrEP patients who picked up PrEP prescriptions and extracted medical and pharmacy claims to evaluate a longitudinal cohort during 2012-2018 based on the Connecticut APCD. Patients who did not pick up medication for one consecutive month (ie, 30 days) were defined as discontinuing PrEP. Kaplan-Meier Survival Curve and proportional hazard regression were used to describe PrEP persistence. Of the 1,576 patients who picked up PrEP prescriptions, the median age was 32.0 (interquartile range [IQR]: 22.0-44.0). The majority were male individuals (93%). Of 1,040 patients who discontinued PrEP, 702 (67.5%) restarted PrEP at least once. The median time of PrEP persistence was 3 months (IQR: 1-6 months) for initial PrEP use. The median time on PrEP was also around 3 months in the following episodes of PrEP use. Being female, being on parent's insurance, and having high co-pays were associated with shorter periods of PrEP persistence. PrEP persistence was low among patients who picked up PrEP prescriptions. Although many patients restarted PrEP, persistence remained low during follow-up PrEP use and possibly led to periods of increased HIV risk. Effective interventions are needed to improve PrEP persistence and reduce HIV incidence.
