The Effects of Prior Authorization on Medicaid Prescription Drug Access

Principal Investigator: Abby Alpert, PhD | The Wharton School

Prescription drug spending has increased rapidly over the last two decades. In response, state Medicaid programs have implemented prior authorization policies to reduce drug spending and improve the targeting of treatment. Despite the prevalence and importance of these policies in state Medicaid programs, there is limited evidence of their impact on prescription drug access and patient outcomes. In this project, we will use a regression-discontinuity design to study the consequences of prior authorization policies on prescription drug access as well as heterogeneous impacts across geographic areas and socio-demographic characteristics. We will also assess the role of different design features of these policies and their impact on inappropriate and appropriate prescribing.

Implementation of Warmline+bridge: An Innovative Approach to Address Opioid Use Disorder Treatment Gaps in Philadelphia

Principal Investigator: Shoshana Aronowitz, PhD, FNP-BC, MSHP | School of Nursing

More than 100,000 people in the U.S. died of a drug overdose during the one-year period ending in April 2021. This study will assess and improve the implementation and sustainability of Warmline+bridge, an innovative program at Penn Medicine on Demand (PMOD). The purpose of Warmline+bridge, established in October 2021, is to connect Philadelphians with opioid use disorder (OUD) to treatment programs across the city and to provide same-day “bridge prescriptions” of buprenorphine via telehealth. Philadelphia urgently needs this intervention as the city experienced the second highest overdose death rate of any U.S. metro area in 2020 with over 1,200 fatalities, and most individuals with OUD lack access to evidence-based treatment with medications like buprenorphine. Findings from this study will inform actionable ways to successfully implement, sustain, and scale this care delivery model at PMOD and beyond.

Knowledge and Perspectives of Low-Income Caregivers on a New Statewide Children’s Savings Account Initiative

Principal Investigator: Zoe Bouchelle, MD | Perelman School of Medicine

Low-income caregivers face barriers to enrollment in a statewide education savings program. Enrollment may be increased by simplifying registration, expanding the investment amount, and conducting clinic- and community-based outreach. Clinic-based financial counseling represents a promising model to connect families to education savings programs and other financial services. Future research should examine the effectiveness of clinic-based financial services in connecting low-income families to financial services and the associated long-term financial and health impacts.

The Impact of Medicaid Policies on Long-Term Care Workers’ Economic Outcomes

Principal Investigator: Pilar Gonalons-Pons, PhD | School of Arts & Sciences

The long-term care industry is one of the fastest growing sectors of the economy, but also creates some of the lowest-paid and lowest-quality jobs. The precarious working conditions of long-term care workers—who are disproportionately women and women of color—are costly for both the workers and the patients they care for. This study will examine the role of government policy in shaping the economic conditions of this critical workforce by analyzing whether and how Medicaid long-term care policies shape care workers’ economic outcomes and job characteristics, in particular wages, access to benefits, schedule predictability, and union membership.

Improving Early-Stage OUD Treatment in Primary Care

Principal Investigator: Rebecca (Arden) Harris, MD, MSc | Perelman School of Medicine

About two-thirds of all patients with opioid use disorder (OUD) who begin outpatient buprenorphine treatment discontinue within the first six months, with nearly half of the attrition occurring in the first 30 days. To better understand early treatment dropout in primary care, we conducted semi-structured interviews of patient participants who had completed the first 4 weeks of OUD treatment in primary care or had discontinued treatment during the first 4 weeks. We also conducted interviews with clinicians and administrators for additional perspectives. Some themes identified were: (1) greater appointment and walk-in availability help prevent dropout, but limiting MOUD hours conserves scarce clinic resources; (2) high-risk comorbidities (chronic pain, stimulant and benzodiazepine use) present challenges to the development of the patient-PCP relationship; (3) PCP group coverage models may hinder patient-PCP relationships; (4) insurance lapses, high copays, and transportation costs impair early retention; (5) telemedicine decreases barriers to MOUD, but some guardrails may be useful.

A Proactive, Tailored, Population Health Approach for Tobacco Treatment for Parent Smokers through a Pediatric Care Network

Principal Investigator: Brian Jenssen, MD, MSHP | Perelman School of Medicine

Routinely delivered tobacco treatment to parents who smoke would provide a major health benefit in the U.S., as tobacco use leads to 480,000 preventable deaths, $300 billion in tobacco attributable costs, and secondhand smoke (SHS) exposure that affects more than 40% of children each year. Pediatricians are uniquely positioned to protect children from SHS exposure by helping medically underserved parents quit smoking. However, appropriate treatments are rarely provided to parents/caregivers who smoke and strategies are needed to engage household members who smoke and are not present at the child’s health care visit. Our team has created a clinical decision support (CDS) system deployed within the Children’s Hospital of Philadelphia (CHOP) Primary Care Network that captures when there are household members not at the visit who smoke and gets permission to contact them. Funding from this grant will be used to test how best to engage these parents in treatment.

Trends and Factors Associated with Hospital and Pharmacy Contracting in the 340B Drug Pricing Program

Principal Investigator: John Lin, MD, MSHP | MD Anderson Cancer Center, University of Texas

Substantial growth occurred following the 2010 340B expansion—by 2019, nearly one-third of all pharmacies were contracting with a 340B institution. The vast majority were retail pharmacies. Contract pharmacy growth was concentrated in affluent and predominantly white neighborhoods, whereas the share of 340B pharmacies in socioeconomically disadvantaged and primarily non-Hispanic Black and Hispanic/Latino neighborhoods declined.

FQHC Based Integrated Care for Serious Mental Illness

Principal Investigator: Steven Marcus, PhD | School of Social Policy & Practice

Access to quality integrated primary care and behavioral health services is critical to addressing disparate health outcomes among individuals with serious mental illness (SMI) and chronic health conditions. Many individuals with SMI and chronic disease rely on federally qualified health centers (FQHCs) to receive care, though research examining how FQHCs can best deliver integrated behavioral health (IBH) to this group is lacking. This study will examine how individuals with SMI and chronic disease utilize IBH services within FQHCs, and what type of IBH leads to best outcomes for this group. The study will identify patient, organizational, and community-level factors affecting patterns of IBH utilization among individuals with SMI and chronic disease, examine how patterns of IBH utilization affects service quality and clinical outcomes among this group, and explore factors moderating this relationship.

Understanding Prognostic Communication Between Clinicians and Surrogates of Older Adults with Moderate to Severe Traumatic Brain Injury: A Qualitative Study

Principal Investigator: Stephen Miranda, MD | Perelman School of Medicine

Older adults account for a disproportionate number of deaths after traumatic brain injury (TBI), often necessitating urgent, value-laden conversations about life-saving surgery. Because an acceptable neurological status or functional outcome is not guaranteed post-operatively, it is critical to understand how clinicians and patient surrogates communicate about the future. This project will yield essential information about how prognosis is disclosed and perceived after TBI, using qualitative methods to: (a) describe the content of care-planning discussions between clinicians and surrogates, and (b) explore surrogate perceptions about prognostic communication. Such evidence will inform the development of behavioral interventions to improve shared decision-making after these injuries so that surrogate expectations are better aligned with realistic outcomes, and that recommended treatments are more concordant with patient values.

Evaluating the Early Impact of the End-Stage Renal Disease Treatment Choices Model on Health Equity

Principal Investigator: Amol Navathe, MD, PhD | Perelman School of Medicine

Patients with end-stage renal disease (ESRD) suffer from limited and inequitable access to cost-effective therapies such as home dialysis or kidney transplantation (compared to in-center hemodialysis). To improve access to these therapies, the Centers for Medicare and Medicaid Services implemented a new mandatory payment model in 2021—the ESRD treatment choices (ETC) model—which randomized 30% of all hospital referral regions in the country to receive payment adjustments that incentivize home dialysis and kidney transplantation. Unfortunately, there is growing concern that the randomization design may unintendedly worsen access to these therapies for minority populations. In this proposal, we will leverage data from Medicare and transplant registries to evaluate the impact of the ETC model on health equity. Specifically, we aim to establish whether the ETC model 1) appropriately randomized participants to account for equity, and 2) had an early impact on home dialysis and kidney transplant waitlisting for minority populations.
