Specialty drug coverage varies between health plans' medical and pharmacy benefit policies.

BACKGROUND: In an effort to control drug spending, health plans are increasingly shifting specialty drugs from their medical benefit to the pharmacy benefit. One consequence of this trend is that some health plans have both a medical and a pharmacy coverage policy for the same drug. OBJECTIVE: To examine how frequently health plans issue medical and pharmacy benefit policies for the same specialty drug and to evaluate the concordance between plans' medical and pharmacy policies when plans issue both policy types. METHODS: We identified specialty drug coverage policies from the Tufts Medical Center Specialty Drug Evidence and Coverage Database, which includes policies issued by 17 of the largest US commercial health plans. Policies were current as of August 2020. We determined plans that issued both medical and pharmacy policies. Next, we identified drugs with "medical-pharmacy policy pairs," ie, drugs for which a plan issued both a medical and a pharmacy policy. For these pairs, we compared the plan's policies while accounting for the following coverage criteria: patient subgroups (patients must meet certain clinical criteria), prescriber requirements (a specialist must prescribe the drug), and step therapy protocols (patients must first fail alternative treatments). We considered medical-pharmacy policy pairs to be discordant if coverage criteria differed, eg, the medical policy included a prescriber requirement but the pharmacy policy did not. RESULTS: Eight plans issued separate medical and pharmacy benefit coverage policies for the same specialty drug and indication. Among these 8 plans, we identified 1,619 medical-pharmacy policy pairs. Eighty-six percent of pairs were concordant (1,386/1,619), and 14% were discordant (233/1,619). Discordance was most often due to differences in plans' application of step therapy protocols (184/233), followed by prescriber requirements (52/233) and patient subgroups (25/233). Forty pairs were discordant in multiple ways. Of discordant pairs, medical policies were more restrictive 41% (96/233) of the time; pharmacy policies were more restrictive 54% (125/233) of the time; 5% of the time (12/233), the medical policy was more restrictive in some ways, but the pharmacy policy was more restrictive in others. Overall, plans imposed coverage restrictions in their medical and pharmacy policies with similar frequencies. CONCLUSIONS: Commercial health plans' medical and pharmacy coverage policies for the same specialty drugs tended to be concordant, although we found coverage criteria to be discordant 14% of the time. Medical and pharmacy policies that are inconsistent in their coverage criteria and restrictions complicate, and potentially hinder, patients' access to specialty drugs.

R-scale for pulmonary fibrosis: a simple, visual tool for the assessment of health-related quality of life.

RATIONALE: Patients with idiopathic pulmonary fibrosis (IPF) experience impaired health-related quality of life (HRQoL). Several tools have been developed to objectively assess HRQoL in this patient population, but none are in use in routine clinical practice. OBJECTIVES: To develop a rapid, specific tool that can be used for patients with IPF during routine clinic visits. METHODS: A novel and simple five-item numerical rating scale was developed and compared with two other previously validated tools. 100 consecutive patients with IPF managed at a centre for interstitial lung disease were recruited to complete the Raghu scale for pulmonary fibrosis (R-Scale-PF), King's Brief Interstitial Lung Disease questionnaire (K-BILD), and the EuroQol Five-Dimensional Five-Level questionnaire (EQ-5D-5L) in addition to pulmonary function and 6-min walk tests. MEASUREMENTS AND MAIN RESULTS: All 100 patients successfully completed the three HRQoL tools with 53 completing them again at follow-up visits. Internal consistency was high (Cronbach's α 0.825) with minimal floor/ceiling effect. Concurrent validity of the R-Scale-PF was moderate to high compared with the K-BILD (r=-0.713) and the EQ-5D-5L (r=-0.665). Concurrent validity was moderate with physiologic measures (forced vital capacity, r=-0.307, 6-min walking distance, r=-0.383). The R-Scale-PF demonstrated good known-groups validity when comparing scores across stages of disease severity. CONCLUSIONS: The R-Scale-PF correlates well with the K-BILD and EQ-5D-5L. It is hoped that this novel simple numerical rating scale tool, subject to validation in patients from other centres, will provide an opportunity to objectively measure HRQoL in routine clinical practice for patients with IPF.

Impact of Abstinence and of Reducing Illicit Drug Use Without Abstinence on Human Immunodeficiency Virus Viral Load.

BACKGROUND: Substance use is common among people living with human immunodeficiency virus (PLWH) and a barrier to achieving viral suppression. Among PLWH who report illicit drug use, we evaluated associations between HIV viral load (VL) and reduced use of illicit opioids, methamphetamine/crystal, cocaine/crack, and marijuana, regardless of whether or not abstinence was achieved. METHODS: This was a longitudinal cohort study of PLWH from 7 HIV clinics or 4 clinical studies. We used joint longitudinal and survival models to examine the impact of decreasing drug use and of abstinence for each drug on viral suppression. We repeated analyses using linear mixed models to examine associations between change in frequency of drug use and VL. RESULTS: The number of PLWH who were using each drug at baseline ranged from n = 568 (illicit opioids) to n = 4272 (marijuana). Abstinence was associated with higher odds of viral suppression (odds ratio [OR], 1.4-2.2) and lower relative VL (ranging from 21% to 42% by drug) for all 4 drug categories. Reducing frequency of illicit opioid or methamphetamine/crystal use without abstinence was associated with VL suppression (OR, 2.2, 1.6, respectively). Reducing frequency of illicit opioid or methamphetamine/crystal use without abstinence was associated with lower relative VL (47%, 38%, respectively). CONCLUSIONS: Abstinence was associated with viral suppression. In addition, reducing use of illicit opioids or methamphetamine/crystal, even without abstinence, was also associated with viral suppression. Our findings highlight the impact of reducing substance use, even when abstinence is not achieved, and the potential benefits of medications, behavioral interventions, and harm-reduction interventions.

Brief Report: Reduced Use of Illicit Substances, Even Without Abstinence, Is Associated With Improved Depressive Symptoms Among People Living With HIV.

PURPOSE: Substance use is linked with poor outcomes among people living with HIV (PLWH) and is associated with mental health disorders. This analysis examines the impact of decreasing substance use, even without abstinence, on depressive symptoms among PLWH. METHODS: Data are from PLWH enrolled in the Centers for AIDS Research Network of Integrated Clinical Sites cohort. Participants completed longitudinal assessments of substance use (modified ASSIST) and depressive symptoms (PHQ-9). Changes in substance use frequency were categorized as abstinence, reduced use, and nondecreasing use. Adjusted linear mixed models with time-updated change in substance use frequency and depressive symptom scores were used to examine associations between changes in the use of individual substances and depressive symptoms. Analyses were repeated using joint longitudinal survival models to examine associations with a high (PHQ-9 ≥10) score. RESULTS: Among 9905 PLWH, 728 used cocaine/crack, 1016 used amphetamine-type substances (ATS), 290 used illicit opiates, and 3277 used marijuana at baseline. Changes in ATS use were associated with the greatest improvements in depressive symptoms: stopping ATS led to a mean decrease of PHQ-9 by 2.2 points (95% CI: 1.8 to 2.7) and a 61% lower odds of PHQ-9 score ≥10 (95% CI: 0.30 to 0.52), and decreasing ATS use led to a mean decrease of 1.7 points (95% CI: 1.2 to 2.3) and a 62% lower odds of PHQ-9 score ≥10 (95% CI: 0.25 to 0.56). Stopping and reducing marijuana and stopping cocaine/crack use were also associated with improvement in depressive symptoms. CONCLUSIONS: We demonstrated that both substance use reduction and abstinence are associated with improvements in depressive symptoms over time.

New statin use and left ventricular structure: Estimating long-term associations in the Multi-Ethnic Study of Atherosclerosis (MESA).

PURPOSE: Only small and short-term studies have evaluated statins in relation to changes in heart structure. We estimated the association between new statin use and 10-year remodeling of the left ventricle. METHODS: The Multi-Ethnic Study of Atherosclerosis collected data on statin use over approximately 10 years, conducting cardiac magnetic resonance (CMR) imaging at baseline and the 10-year exam. Participants were free of baseline cardiovascular disease, and we excluded users of statins at baseline. Statin initiation was defined as a report of current use at any of the 4 subsequent exams. Primary outcomes were the change in left ventricular mass index (LVMI; % predicted by height, weight, and sex) and mass-to-volume ratio. Associations were estimated in a propensity score-matched analysis. RESULTS: A total of 3113 participants (53% female; 40% European-American, 25% African-American, 22% Hispanic-American, and 13% Chinese-American) were eligible; 2431 returned for follow-up CMR imaging after a median of 9.4 years. Statin therapy (moderate dose, 76%) was started by 36% of participants (N = 872). We excluded 42 participants with incident myocardial infarction. Compared with nonuse, statin use was associated with less 10-year progression in LVMI (-2.35 percentage points; 95% CI, -4.24 to -0.47; P = .01) and mass-to-volume ratio (-0.03 absolute difference; 95% CI, -0.07 to -0.00; P = .02); effects were small in magnitude. A dose response was observed: Higher statin dose was associated with less LVMI progression. CONCLUSIONS: In contrast to previous small studies, we found very modest associations between statin use and indices of left ventricular remodeling over 10 years in this prospective study of a diverse cohort.

Cohort profile: seek, test, treat and retain United States criminal justice cohort.

BACKGROUND: The STTR treatment cascade provides a framework for research aimed at improving the delivery of services, care and outcomes of PLWH. The development of effective approaches to increase HIV diagnoses and engage PLWH in subsequent steps of the treatment cascade could lead to earlier and sustained ART treatment resulting in viral suppression. There is an unmet need for research applying the treatment cascade to improve outcomes for those with criminal justice involvement. METHODS: The Seek, Test, Treat, and Retain (STTR) criminal justice (CJ) cohort combines data from 11 studies across the HIV treatment cascade that focused on persons involved in the criminal justice system, often but not exclusively for reasons related to substance use. The studies were conducted in a variety of CJ settings and collected information across 11 pre-selected domains: demographic characteristics, CJ involvement, HIV risk behaviors, HIV and/or Hepatitis C infections, laboratory measures of CD4 T-cell count (CD4) and HIV RNA viral load (VL), mental illness, health related quality of life (QoL), socioeconomic status, health care access, substance use, and social support. RESULTS: The STTR CJ cohort includes data on 11,070 individuals with and without HIV infection who range in age from 18 to 77 years, with a median age at baseline of 37 years. The cohort reflects racial, ethnic and gender distributions in the U.S. CJ system, and 64% of participants are African-American, 12% are Hispanic and 83% are men. Cohort members reported a wide range of HIV risk behaviors including history of injection drug use and, among those who reported on pre-incarceration sexual behaviors, the prevalence of unprotected sexual intercourse ranged across studies from 4% to 79%. Across all studies, 53% percent of the STTR CJ cohort reported recent polysubstance use. CONCLUSIONS: The STTR CJ cohort is comprised of participants from a wide range of CJ settings including jail, prison, and community supervision who report considerable diversity in their characteristics and behavioral practices. We have developed harmonized measures, where feasible, to improve the integration of these studies together to answer questions that cannot otherwise be addressed.

Meta-analysis for the association between overall survival and progression-free survival in gastrointestinal stromal tumor.

PURPOSE: Gastrointestinal stromal tumor (GIST) is a relatively rare tumor that is treated with targeted therapies in advanced stages. Randomized clinical trials (RCT) often require long follow-up and large sample sizes to evaluate overall survival (OS), the gold-standard measure of treatment efficacy. However, changes in therapy following disease progression may complicate survival assessments. Establishing surrogate endpoints may facilitate the drug approval and availability of new efficacious treatments; however, no published studies have investigated this topic in unresectable and/or metastatic GIST. EXPERIMENTAL DESIGN: A systematic literature review identified 14 RCTs and five observational studies of sufficient methodologic quality published between January 1995 and December 2013 (29 treatment arms; 2,189 patients). Weighted linear regression was used to evaluate the relation between median OS and median progression-free survival (PFS) for all arms combined and stratified by treatment line, treatment type, and quality score. RESULTS: Median OS and PFS were positively related with a correlation of 0.91. The association was still moderate (correlation 0.72) after eliminating four influential data points. In stratified analyses, correlation of OS and PFS was greater in later lines of therapy (first line = 0.52; second line = 0.80; third- and later-line = 0.70) and imatinib showed a stronger association (0.91) than other evaluated treatments (-0.26 to 0.69). CONCLUSION: This analysis identified a strong relationship between median OS and PFS, especially in later lines of therapy. Findings suggest that PFS could serve as a surrogate marker for OS; however, analyses of patient-level data are needed to establish its validity in GIST.
