Patient and provider-level factors associated with changes in utilization of treatments in response to evidence on ineffectiveness or harm.
High-quality health care not only includes timely access to effective new therapies but timely abandonment of therapies when they are found to be ineffective or unsafe. Little is known about changes in use of medications after they are shown to be ineffective or unsafe. In this study, the investigators examined changes in use of two medications: fenofibrate, which was found to be ineffective when used with statins among patients with Type 2 diabetes (ACCORD lipid trial); and dronedarone, which was found to be unsafe in patients with permanent atrial fibrillation (PALLAS trial).

Antenatal corticosteroid administration in late-preterm gestations: a cost-effectiveness analysis.
The purpose of this study was to evaluate whether administration of antenatal late-preterm betamethasone was cost-effective in the immediate neonatal period. Cost-effectiveness analysis of late-preterm betamethasone administration with a time horizon of 7.5 days was conducted using a health-system perspective The investigators concluded that administration of betamethasone in the late-preterm period was likely not cost-effective in the short-term.

The effect of Medicaid expansion on prescriptions for breast cancer hormonal therapy medications.
The purpose of this study was to quantify the effects of the Affordable Care Act Medicaid expansion on prescriptions for effective breast cancer hormonal therapies (tamoxifen and aromatase inhibitors) among Medicaid enrollees. Data from the Medicaid State Drug Utilization Database was used. Findings showed that Medicaid expansion may have had a meaningful impact on the ability of lower-income women to access effective hormonal therapies used to treat breast cancer.

Tobacco cessation in Affordable Care Act Medicaid expansion states versus non-expansion states.
This study examined whether states that expanded Medicaid eligibility under the ACA had increased smoking quit rates, tobacco cessation medication orders, and greater health care utilization compared to patients in non-expansion states. The researchers used electronic health record (EHR) data from 219 community health centers (CHCs) in 10 states that expanded Medicaid as of January 2014. They identified patients aged 19-64 with tobacco use status in their records within six months prior to ACA Medicaid expansion and 1 or more visits. They found that patients in expansion states had increased adjusted odds of quitting, having a medication ordered and having follow-up visits compared to patients in non-expansion states.

Impact of Medicaid expansion on access and healthcare among individuals with sickle cell disease.
The purpose of this study was to examine whether Medicaid expansion in California, increased Medicaid enrollment, increased hydroxyurea prescriptions filled, and decreased acute healthcare utilization in sickle cell disease (SCD). Findings showed that Medicaid expansion did not appear to have improved enrollment or acute healthcare utilization among individuals with SCD in California. Recommendations included future studies exploring whether individuals with SCD transitioned to other insurance plans or became uninsured post-expansion, the underlying reasons for low hydroxyurea utilization, and the lack of effect on hospital admissions despite a modest effect on emergency department visits.

Prescription patterns and opioid usage in sinonasal surgery.
The goal of this study was to identify factors associated with variable opioid usage and to delineate optimal prescription patterns for sinonasal surgery. The researchers found that patients used 9.3% of their full prescription and only 2.6% required a refill. The amount used was not associated with complexity of endoscopic sinus surgery, type of opiate prescribed, gender, distance living from hospital, or current opioid usage before surgery. They concluded that opioids are overprescribed after sinonasal surgery and that the amount of postoperative opiate prescribed should be greatly reduced and may be based on the specific procedures performed.

Sickle-cell disease co-management, health care utilization, and hydroxyurea use.
Sickle-cell disease (SCD) causes significant morbidity, premature mortality, and high disease burden, resulting in frequent health care use. Comanagement may improve utilization and patient adherence with treatments such as Hydroxyurea. The purpose of this study was to describe acute-care utilization in Medicaid-enrolled patients with SCD, patient factors associated with comanagement, and adherence to Hydroxyurea. The investigators concluded that comanagement was a factor in predicting HUadherence, but further studies are needed to identify the frequency and components of comanagement needed to increase adherence and reduce acute care utilization.

Impact of FDA black box warning on fluoroquinolone and alternative antibiotic use in southeastern US hospitals.
This study’s objective was the quantify the effect of the 2016 FDA “black box” update on the use of fluoroquinolone antibiotics among a cohort of southeastern US hospitals. Fluoroquinolone was given a black box warning after many serious adverse events were reported. Antibiotic use data from 29 southeastern US hospitals over a 5-year period was analyzed. Fluoroquinolone use declined both and before after the FDA advisory update in 2016.

Ngo-Metzger Q, Zuvekas S, Shafer P, Tracer H, Borsky AE, Bierman AS. Statin use in the U.S. for secondary prevention of cardiovascular disease remains suboptimal.
Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of mortality in the United States. The purpose of this study was to examine the rates of statin use for secondary prevention of ASCVD events in the United States over the last decade and determine whether disparities in the treatment of ASCVD still persist among women and racial/ethnic minorities.

Stepped-wedge randomised trial to evaluate population health intervention designed to increase appropriate anticoagulation in patients with atrial fibrillation.
Clinical guidelines recommend anticoagulation for patients with atrial fibrillation (AF) at high risk of stroke; however, studies report 40% of this population is not anticoagulated. The purpose of this study was to evaluate a population health intervention to increase anticoagulation use in high-risk patients with AF. The investigators concluded that algorithms to identify underuse of anticoagulation among patients with AF in healthcare databases may not capture clinical subtleties or patient preferences and may overestimate the extent of undertreatment.

Decomposing changes in the growth of U.S. prescription drug use and expenditures, 1999-2016.
Data from the Medical Expenditure Panel Survey (MEPS) was examined to analyze factors associated with changes in prescription drug use and expenditures in the US from 1999 to 2016. There were large increases in prescription drug use during that period, with per capita utilization increasing by nearly half and per capita expenditures more than doubled. Treatment of long-term conditions was a large driver in the increases in medication use.

Longitudinal pattern of pain medication utilization in peripheral neuropathy patients.
The authors of this article investigated the pattern and utilization of neuropathic pain medications in peripheral neuropathy patients. They found that opioid initiation and transition to chronic opioid therapy were frequent in the studied population despite few patients receiving more than one guideline-recommended medication. They concluded that efforts are needed to decrease opioid utilization and to increase guideline-recommended medication use in order to improve current neuropathic pain treatment.

Health care utilization of opioid overdose decedents with no opioid analgesic prescription history.
In this study, to better understand the role of prescription opioids and health care utilization prior to opioid-related overdose, the investigators analyzed the death records of decedents who died of an opioid overdose in Illinois in 2016 and linked to any existing controlled substance monitoring program (CSMP) and emergency department (ED) or hospital discharge records.

The effect of health insurance on prescription drug use among low-income adults: evidence from recent Medicaid expansions.
This study examined how subsidized coverage affected prescription drug utilization among low-income non-elderly adults. Among other results, the investigators found that within the first 15 months of new health insurance availability, aggregate Medicaid-paid prescriptions increased 19 percent, amounting to nearly 9 new prescriptions a year, per new enrollee. They also found no evidence of reductions in uninsured or privately-insured prescriptions, suggesting that new coverage did not simply substitute for other payment sources.
