Uptake of hepatitis C virus treatment in a multi-state Medicaid population, 2013-2017.

OBJECTIVE: To examine trends in the direct acting antiviral (DAA) uptake in a multi-state Medicaid population with hepatitis C virus (HCV) prior to and after ledipasvir/sofosbuvir (LDV/SOF) approval and changes in prior authorization (PA) requirements. DATA SOURCES: Analyses utilized enrollment, medical, and pharmacy claims in four states, December 2013-December 2017. STUDY DESIGN: An interrupted time series examined trends in uptake (1+ claim for a DAA) before and after two events: LDV/SOV approval (October 2014) and lifting of PA requirements for 40% of members (July 2016). Analyses were also performed in subgroups defined by the number and dates of change in PA requirements in members' Medicaid plans. DATA COLLECTION/EXTRACTION METHODS: Members aged 18-64 years with an ICD code for HCV were included in the sample from diagnosis date until treatment initiation or Medicaid disenrollment. PRINCIPAL FINDINGS: The annual sample size ranged from 38,302 to 45,005 with approximately 30% ages 18-34 years and 40% female. In December 2013, 0.08% was treated, rising to 0.74% in December 2017 (p < 0.001). Uptake increased from 0.34%/month in October 2014 to 0.70%/month after LDV/SOF approval, (p < 0.001), and increased relative to the pre-LDV/SOV trend through June 2016 (p = 0.04). Uptake increased to 1.18%/month after PA change, (p < 0.001) and remained flat through 2017 (p = 0.64). Cumulatively, 20.1% were treated by December 2017. In plans with few/no requirements through 2017, uptake increased to 1.19%/month after LDV/SOF approval (p < 0.001) and remained flat through 2017 (p = 0.11), with 22.2% cumulatively treated. Among plans that lifted PA requirements from three to zero in mid-2016, uptake did not increase after LDV/SOF approval (p = 0.36) but did increase to 1.41%/month (p < 0.001) after PA change, with 18.1% cumulatively treated. CONCLUSIONS: HCV Treatment increased through 2017. LDV/SOF approval and lifting PA requirements led to an increase in uptake followed by flat monthly utilization. Cumulative uptake was higher in plans with few/no PA requirements relative to those with three requirements through mid-2016.

Time trends in emergency department use among adults with intellectual and developmental disabilities.

BACKGROUND: Emergency Department (ED) visits are common among adults with intellectual and developmental disabilities (IDD). However, little is known about how ED use has varied over time in this population, or how it has been affected by recent Medicaid policy changes. OBJECTIVE: To examine temporal trends in ED use among adult Medicaid members with IDD in eight states that ranged in the extent to which they had implemented state-level Medicaid policy changes that might affect ED use. METHODS: We conducted repeated cross-sectional analyses of 2010-2016 Medicaid claims data. Quarterly analyses included adults ages 18-64 years with IDD (identified by diagnosis codes) who were continuously enrolled in Medicaid for the past 12 months. We assessed change in number of ED visits per 1000 member months from 2010 to 2016 overall and interacted with state level policy changes such as Medicaid expansion. RESULTS: States with no Medicaid expansion experienced an increase in ED visits (linear trend coefficient: 1.13, p < 0.01), while states operating expansion via waiver had a much smaller (non-significant) increase, and states with ACA-governed expansion had a decrease in ED visits (linear trend coefficient: 1.17, p < 0.01). Other policy changes had limited or no association with ED visits. CONCLUSIONS: Medicaid expansion was associated with modest reduction or limited increase in ED visits compared to no expansion. We found no consistent decrease in ED visits in association with other Medicaid policy changes.

Evaluation of Progesterone Utilization and Birth Outcomes in a State Medicaid Plan.

OBJECTIVES: Progesterone (hydroxyprogesterone caproate injection and vaginal progesterone) has been shown to reduce preterm birth (PTB) rates by a third among pregnant women at high risk. The purpose of this analysis is to report birth outcomes and medication adherence among Massachusetts Medicaid (MassHealth) members receiving progesterone, evaluate the association between member characteristics and birth outcomes and medication adherence, and compare cost of care with a prior preterm pregnancy. METHODS: This retrospective cohort study used medical claims, pharmacy claims, and prior authorization (PA) request data for MassHealth members who had a PA submitted for progesterone between January 1, 2011, and March 31, 2015. Members were excluded due to breaks in coverage, progesterone was not indicated for prevention of PTB, and if current gestational week or date of delivery was unavailable. MAIN RESULTS: A total of 418 members were screened for inclusion of whom 190 met criteria and 169 filled progesterone. Mean age was 29.2 years (SD = 5.23), and clinical comorbidities were identified in 90.5% of members. Consistent with clinical trials on progesterone effectiveness, 62.1% of members had a term delivery (37 wks of gestation). Among members with prior gestational age at delivery available, the average difference in gestational age between pregnancies was 8.25 weeks (SD = 6.11). In addition, 66.3% of members were adherent to progesterone based on proportion of days covered (PDC) of 0.8 or higher. The overall mean PDC was 0.79 (SD = 0.26). CONCLUSION: Despite similar birth outcomes in clinical trials and national trends, medication adherence is low in this state Medicaid program. Therefore, members may benefit from adherence support.

Access to New Medications for Hepatitis C for Medicaid Members: A Retrospective Cohort Study.

BACKGROUND: Sofosbuvir (SOF)- or simeprevir (SIM)-containing regimens are highly effective for treating chronic hepatitis C virus (HCV) infection. These regimens, however, are expensive. Most payers have implemented prior authorization (PA) requirements to ensure that patients who can benefit most have priority for these medications. While many Medicaid programs limit access to those with advanced disease or to members who do not have active substance use disorder (SUD), the Massachusetts Medicaid (MassHealth) Primary Care Clinician (PCC) plan does not limit access based on disease severity or presence of SUD. Evaluating PA requests for SOF and/or SIM among MassHealth members will offer a useful example of early uptake among Medicaid members and will identify patient groups who might face barriers to treatment at the provider or patient level. OBJECTIVES: To (a) evaluate the percentage of MassHealth PCC members with HCV who had a PA request, along with the percentage of requests approved, and (b) identify characteristics associated with PA requests for SOF or SIM among Massachusetts Medicaid (MassHealth) members with HCV. METHODS: This retrospective cohort study used enrollment, medical claims, and PA request data from MassHealth PCC members from December 6, 2012, to July 31, 2014. The sample included members with 1 or more claims with an ICD-9-CM code for HCV during this time who were continuously enrolled from December 6, 2013, to July 31, 2014. Enrollment and medical claims data for the cohort with HCV were linked to a database containing information collected from PA requests. The overall percentage of members with HCV and a PA request for SOF and/or SIM between December 6, 2013, and July 31, 2014, and the percentage of requests approved were calculated. Chi-square statistics were used to compare demographic and clinical characteristics among members with HCV who did and did not have a request. Logistic regression was used to estimate the strength of associations between patient characteristics and a PA treatment request, adjusting for clinical and demographic variables. RESULTS: Of 6,849 members identified with HCV, 346 (5.1%) had a PA request for SOF and/or SIM submitted to MassHealth. Compared with members with HCV who did not have a PA request for SOF or SIM, those with a PA request for these new treatments were more likely to be male (P = 0.01), older (P < 0.001), white race (P = 0.04), have standard MassHealth insurance (P = 0.01), and less likely to be homeless (P < 0.001). Members with a PA request were also more likely to have been treated for HCV in the past year and have advanced disease (hepatic decompensation, cirrhosis, or liver transplant) but less likely to have SUD (P < 0.001 for each). Ninety percent of requests for SOF or SIM were approved; few demographic or clinical characteristics were associated with approval. In adjusted analyses, predictors of PA request were aged 50-64 years (odds ratio (OR) = 2.0, 95% CI = 1.1-3.7 vs. aged < 30 years); hepatic decompensation (OR = 1.6, 95% CI = 1.2-2.3); cirrhosis (OR = 3.0, 95% CI = 2.2-4.1); liver transplant (OR = 3.0, 95% CI = 1.4-6.5); substance use (OR = 0.6, 95% CI = 0.5-0.8); recent HCV treatment (OR = 1.6, 95% CI = 1.0-2.6); comorbidity (OR = 0.95, 95% CI = 0.91-0.98) for 1-unit increase in Diagnostic Cost Group score; and care at a hospital outpatient department (OR = 2.0, 95% CI = 1.2-3.2 vs. group practice). CONCLUSIONS: Antiviral treatment with SOF and/or SIM was requested for a relatively small proportion of MassHealth members with HCV, with nearly all approved. Prescriber prioritization or patient barriers to care, rather than the PA process, determined access to treatment in this Medicaid population. Support may be needed to ensure patients with SUD benefit from advances in HCV treatment. DISCLOSURES: No outside funding supported this research.

Improving population health through integration of primary care and public health: providing access to physical activity for community health center patients.

OBJECTIVES: Our community health center attempted to meet public health goals for encouraging exercise in adult patients vulnerable to obesity, diabetes, hypertension, and other chronic diseases by partnering with a local YMCA. METHODS: During routine office visits, providers referred individual patients to the YMCA at no cost to the patient. After 2 years, the YMCA instituted a $10 per month patient copay for new and previously engaged health center patients. RESULTS: The copay policy change led to discontinuation of participation at the YMCA by 80% of patients. Patients who persisted at the YMCA increased their visits by 50%; however, more men than women became frequent users after institution of the copay. New users after the copay were also more likely to be younger men. Thus the copay skewed the population toward a younger group of men who exercised more frequently. Instituting a fee appeared to discourage more tentative users, specifically women and older patients who may be less physically active. CONCLUSIONS: Free access to exercise facilities (rather than self-paid memberships) may be a more appropriate approach for clinicians to begin engaging inexperienced or uncertain patients in regular fitness activities to improve health.
