State variation in opioid treatment policies and opioid-related hospital readmissions.
In this study, the investigators used 2013-2015 hospital inpatient discharge data from 13 states from the Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project to examine the relationship between state opioid treatment policies and 90-day opioid-related readmissions after a stay involving an opioid diagnosis. The concluded that differences in index hospitalization rates suggested that states with opioid treatment policies had a higher level of need for opioid-related intervention, which also may account for higher rates of readmission.

First opioid prescription and subsequent high-risk opioid use: a national study of privately insured and Medicare Advantage adults.
This study examined the association between a first opioid prescription and high-risk opioid use in the 18 months following the first prescription. A retrospective cohort study was conducted using data from a large commercial insurance claims database for patients aged 18-64 and also Medicare Advantage patients aged 65 or older for 2011-2014. The patients initially had not used opioids. The features the researchers were looking for were: 1) opioid or benzodiazepine prescriptions overlapping 7 days or more, 2) opioid prescriptions overlapping for 7 days or more; 3) three or more prescribers of opioids; and 4) a daily dosage exceeding 120 morphine milligram equivalents, in each of the six quarters following the first prescription. All of those features were strongly associated with high-risk use.

Risk factors for discontinuation of buprenorphine treatment for opioid use disorders in a multi-state sample of Medicaid enrollees.
The purpose of this study was to examine duration of buprenorphine treatment for opioid use disorder (OUD) following the initiation of treatment in order to identify risk factors for early discontinuation. Researchers analyzed insurance claims from the MarketScan multi-state Medicaid database for 2013 through 2015; their sample included adults aged 18-64 years who had an OUD diagnosis 6 months before initiating buprenorphine treatment. More than 1/4 of the sample discontinued buprenorphine in the first month of treatment, and most of the sample discontinued before 180 days. Risk factors for discontinuation were associated with significantly lower odds of treatment retention for at least 180 days. The study concludes that there is need to implement treatment models that address barriers to treatment retention more effectively.

Understanding how primary care clinicians make sense of chronic pain.
This research explored how primary care clinicians manage their patients with chronic noncancer pain. They conducted Critical Decision Method interviews with 10 clinicians about 30 individual patients. Findings suggested that clinicians should focus on supporting sensemaking in the content of clinical evidence rather than trying to provide them with rules.

Prevalence of preoperative opioid use and characteristics associated with opioid use among patients presenting for surgery.
Researchers assessed the prevalence of preoperative opioid use and the characteristics of patients in a broadly representative surgical cohort. They found that patients undergoing lower extremity procedures were most likely to report preoperative opioid use, with 1 in 4 of all patients presenting for surgery reporting such use. They concluded that the data provided important insights into this population and would appear to help guide future preoperative optimization and perioperative opioid-weaning interventions.

Transitions of care for postoperative opioid prescribing in previously opioid-naive patients in the USA: a retrospective review.
The purpose of this study was to identify specialties prescribing opioids to surgical patients who develop new persistent opioid use. Results showed that, among surgical patients who developed new persistent opioid use, surgeons provided the majority of opioid prescriptions during the first 3 months after surgery, but by 9 to 12 months after surgery, the majority of opioid prescriptions were provided by primary care physicians. Recommendations included enhanced care coordination between surgeons and primary care physicians to allow earlier identification of patients at risk for new persistent opioid use in order to prevent misuse and dependence.

Duration of opioid prescriptions predicts incident nonmedical use of prescription opioids among U.S. veterans receiving medical care.
Although nonmedical use of prescription opioids (NMUPO) is a public health problem, few studies have examined the new-onset NMUPO in clinical populations. This prospective cohort study estimated NMUPO incidence among veterans in medical care who had received prescription opioid medication and examined correlates of new-onset NMUPO. The investigators concluded that duration of prescription opioid receipt was a risk factor for incident NMUPO among veterans receiving medical care.

Pharmacists' role in opioid safety: a focus group investigation.
This qualitative study explores the pharmacist's role in promoting opioid safety from the perspective of pharmacists and patients. Using focus groups, results showed that pharmacists expressed discomfort filling potentially high-risk opioid prescriptions and noted barriers such as lack of clinical information and discomfort policing high-risk prescribing; and that patients were concerned about pharmacists potentially overstepping their professional responsibilities by interfering with prescribers' clinical decisions.

Risks of fatal opioid overdose during the first year following nonfatal overdose.
This study examined that risks of fatal opioid overdose during the first year following nonfatal overdose. A national retrospective longitudinal cohort of patients- aged 18-64 years, in the Medicaid program, who received a clinical diagnosis of nonfatal opioid overdose-was identified. Repeated overdoses and fatal opioid overdoses were measured with the Medicaid record and the National Death Index and rates of repeat overdose per 1000 person-years and fatal overdose per 100,000 person-years were determined.

The effectiveness of internet- and field-based methods to recruit young adults who use prescription opioids nonmedically.
This study researched the effectiveness of field- and Internet-based methods to recruit young adults who are nonmedical prescription opioid (NMPO) users into intervention and treatment. Data was analyzed from the Rhode Island Young Adult Prescription Drug Study (RAPiDS). Internet-based recruitment was more successful (60.1%). Out of 198 eligible participants, median age was 25, and the majority were male, white, and resided in an urban area. Field-based recruited participants were more likely to be homeless, have been incarcerated and engage in daily NMPO use.

Probability of opioid prescription refilling after surgery: does initial prescription dose matter?
In this study, the investigators sought to determine the correlation between the probability of postoperative opioid prescription refills and the amount of opioid prescribed, hypothesizing that a greater initial prescription yields a lower probability of refill. The investigators concluded that the probability of refilling prescription opioids after surgery was not correlated with initial prescription strength, suggesting surgeons could prescribe smaller prescriptions without influencing refill requests.

Causes of death after nonfatal opioid overdose.
The purpose of this study was to describe all-cause mortality rates, selected cause-specific mortality rates, and standardized mortality rate ratios (SMRs) of adults during their first year after nonfatal opioid overdose. In a US national cohort of adults who had experienced a nonfatal opioid overdose, a marked excess of deaths was attributable to a wide range of substance use-associated, mental health, and medical conditions, underscoring the importance of closely coordinating the substance use, mental health, and medical care of this patient population.

Utilization and effectiveness of multimodal discharge analgesia for postoperative pain management.
In this study, the investigators sought to assess the association between discharge multimodal analgesia and postoperative pain outcomes in two diverse health care settings. They evaluated patients undergoing four common surgeries associated with high pain in electronic health records from an academic hospital (AH) and Veterans Health Administration (VHA). The investigators found that a majority of surgical patients received a multimodal pain approach at discharge yet many received only opioids. Multimodal regimen at discharge was associated with better follow-up pain and all-cause readmissions compared to the opioid-only regimen.

Opioid prescribing after curative-intent surgery: a qualitative study using the theoretical domains framework.
To identify targets for intervention, researchers performed a qualitative study of opioid prescribing after curative-intent surgery using the Theoretical Domains Framework, a well-established implementation science method for identifying factors influencing healthcare provider behavior. They concluded that key determinants of opioid prescribing behavior after curative-intent surgery include environmental and social factors. Interventions targeting these factors are likely to improve opioid prescribing in surgical oncology.

Indications for use of combination acetaminophen/opioid drugs in infants <6 months old.
This study examined the use of combination acetaminophen/opioid drugs in infants 0-6 months old. In most cases it is not considered appropriate for children under 2 years and for respiratory diagnosis is not appropriate at all. Pharmacy claims from the South Carolina Medicaid prescriptions database from January 2011 through August 2012 was evaluated. The data was given to researchers in de-identified format from 3 Medicaid files. No newborns (aged <1 month) were given these combination drugs. They calculated that 1 in 5 prescriptions were given for an inappropriate indication, and 1 in 10 for respiratory diagnosis.

Emergency department contribution to the prescription opioid epidemic.
The investigators used MEPS data to characterize the relative contribution of emergency departments (EDs) to national opioid prescribing, to estimate trends in opioid prescribing by site of care, and to examine whether higher-risk opioid users receive a disproportionate quantity of their opioids from ED settings. During the study period, they found that the relative contribution of EDs to the prescription opioid problem was modest and declining. They therefore recommended that further efforts to reduce the quantity of opioids prescribed focus on office-based settings.

Decline in opioid prescribing after federal rescheduling of hydrocodone products.
This study examined differences in opioid prescribing by patient characteristics and variation in hydrocodone combination product (HCP) prescribing attributed to states, before and after the 2014 Drug Enforcement Administration's reclassification of HCP from schedule III to the more restrictive schedule II. It found that HCP prescribing decreased by 26 percent from June 2013 to June 2015; the rate of prescriptions for any opioid decreased by 11 percent.

Opioid prescriptions in older Medicare beneficiaries after the 2014 federal rescheduling of hydrocodone products.
The authors sought to examine how an October 2014 Drug Enforcement Administration policy reclassified hydrocodone product from schedule III to II has affected older adults. They found that the 2014 change in hydrocodone from schedule III to schedule II was associated with modest decreases in rates of opioid use in the elderly. They also found an unexpected increase in opioid-related hospitalizations without documented opioid prescriptions, which may represent an increase in illegal use.

Associations of early opioid use with patient-reported outcomes and health care utilization among older adults with low back pain.
The objective of this study was to compare outcomes and health care utilization of older patients who did versus did not fill opioid prescriptions within 90 days of initiating care for low back pain. Among older patients with new back pain visits, filling 2 or more opioid prescriptions within 90 days of the visit was associated with similar back pain-related outcomes but increased likelihood of filling opioid prescriptions 18 to 24 months later compared with matched patients who did not fill early opioid prescriptions.

Gender differences in trends for heroin use and nonmedical prescription opioid use, 2007-2014.
This study uses National Survey on Drug Use and Health (NSDUH) data to study gender differences in trends for heroin use and nonmedical prescription opioid use from 2007-2014. There has been a steady decline in nonmedical prescription heroin use but a notable increase in heroin use during this period for both men and women. However, women are increasing heroin use at a faster rate than men but their nonmedical prescription opioid use is not decreasing as fast as men. The researchers conclude that more study is needed on gender differences in use and treatment access.

Reduction in opioid prescribing through evidence-based prescribing guidelines.
The authors evaluated the effect of evidence-based postoperative prescribing guidelines in an effort to reduce overprescribing. The post-intervention group received opioid prescriptions for reduced dosages compared to the pre-intervention group. In the post-intervention group, 2.5% requested refills compared with 4.1% in the pre-intervention group. The authors indicated that this work will be used as a template for statewide practice transformation, which may serve as a platform for other states.
