Response: Medicaid enrollees have three times higher risk of opioid overdose than non-enrollees, and for every fatal opioid overdose, there are about 30 nonfatal overdoses, according to the U.S. Centers for Disease Control and Prevention (CDC). My colleagues and I analyzed claims data from 2008 to 2013 for all Pennsylvania Medicaid enrollees aged 12 to 64 years with a medical record of a heroin or prescription opioid overdose and who had six months of continuous enrollment in Medicaid before and after the overdose claim. The 6,013 patients identified were divided into two groups—3,945 who overdosed on prescription opioids and 2,068 who overdosed on heroin, all of whom received treatment for overdose in a hospital or emergency department setting.
We found that Pennsylvania Medicaid recipients who suffer an opioid or heroin overdose continue to be prescribed opioids at high rates, with little change in their use of medication-assisted treatment programs after the overdose. Opioid prescriptions were filled after overdose by 39.7 percent of the patients who overdosed on heroin, a decrease of 3.5 percentage points from before the overdose; and by 59.6 percent of the patients who overdosed on prescription opioids, a decrease of 6.5 percentage points.
Medication-assisted treatment includes coupling prescriptions for buprenorphine, methadone or naltrexone—medications that can reduce opioid cravings—with behavioral therapy in an effort to treat the opioid use disorder. Our team found that such treatment increased modestly among the patients using heroin by 3.6 percentage points to 33 percent after the overdose, and by 1.6 percentage points to 15.1 percent for the prescription opioid overdose patients.

Response: Opioid addiction is a national crisis. As surgery is thought to be a gateway to opioid misuse, opioid-sparing approaches for pain management following surgery are a top priority.
We conducted a meta-analysis of 39 randomized clinical trials of common non-pharmalogical interventions used for postoperative pain management.
We found that acupuncture and electrotherapy following total knee replacement reduced or delayed patients’ opioid use.

Response: Neonatal drug withdrawal is common; in the U.S. about 1 infant is born every 25 minutes with signs of drug withdrawal. Neonatal drug withdrawal is a well-recognized complication of intrauterine exposure to illicit or prescription opioids, but other psychotropic medications can also cause signs of withdrawal. Psychotropic medications are frequently co-prescribed with opioids in pregnancy, and the use of both has increased significantly, raising concerns about an increase in the incidence and severity of neonatal drug withdrawal due to potential drug-drug interactions, but these risks are not well understood.
In this study, we found a 30-60% increase in the risk of neonatal drug withdrawal associated with co-exposure to antidepressants, benzodiazepines and gabapentin, compared to opioids alone; no significant increase in risk was observed for atypical antipsychotics and Z-drugs. Exposure to psychotropic polypharmacy along with opioids was associated with a two-fold increased risk of withdrawal.

Response: In the past 2 decades, consumption of prescription opioids has substantially increased in the U.S. Prescription drugs may cause drowsiness and impaired cognition which may interfere with psychomotor functioning necessary during the operation of a motor vehicle. The current study assessed time trends in prescription opioids detected in drivers killed in motor vehicle crashes from 1995 to 2015 in 6 states in the U.S.
Results of the study showed that the prevalence of prescription opioids detected in fatally injured drivers has increased 700% in the past 2 decades.

Response: The number of patients receiving opioids for chronic pain has risen over the past 2 decades in the US, in parallel with an increase in opioid use disorder. The CDC and professional medical societies have created clinical guidelines to improve the safety of opioid prescribing, yet individual prescribers can find them onerous to implement.
We developed an intervention to change clinical practice to support primary care physicians who prescribe the majority of opioids for chronic pain. The intervention included 4 elements- a nurse care manager to help assess, educate and monitor patients, an electronic registry to keep track of patient data and produce physician level reports, an individualized educational session for the physician by an opioid prescribing expert based on the physician-specific practice information and online resources to help with decision-making for opioid prescribing (www.mytopcare.org). We tested whether the intervention would improve adherence to guidelines, decrease opioid doses and decrease early refills, as a marker of potential prescription opioid misuse among 985 patients of 53 primary care clinicians in four primary care practices.

Response: CDC analyzed retail prescription data from QuintilesIMS which provides estimates of the number of opioid prescriptions dispensed in the United States from approximately 59,000 pharmacies, representing 88% of prescriptions in the United States. CDC assessed opioid prescribing in the United States from 2006 to 2015, including rates, amounts, dosages, and durations prescribed. CDC examined county-level prescribing patterns in 2010 and 2015.

Response: This pivotal Phase 3 clinical trial (RB-US-13-0001) evaluated the efficacy and safety of RBP-6000, an investigational once-monthly injectable buprenorphine in the ATRIGEL® delivery system for the treatment of adults with moderate-to-severe opioid use disorder (OUD) as part of a complete treatment plan to include counseling and psychosocial support1.
The 24-week Phase 3 study met its primary and key secondary endpoints, demonstrating statistically significant differences in percentage abstinence and treatment success across both dosage regimens of RBP-6000 versus placebo1.
The findings also showed that outcomes with RBP-6000 are consistent across other secondary clinical endpoints, including control of craving and withdrawal symptoms, as compared to placebo. These outcomes were associated with buprenorphine plasma concentrations ≥ 2 ng/mL and predicted whole brain mu-opioid receptor occupancy of ≥ 70%, and were also maintained for the one-month dosing intervals and for the entire treatment duration1.
The results were confirmed by exposure-response analyses demonstrating a relationship between buprenorphine plasma concentrations, abstinence, withdrawal symptoms and opioid craving1.
RBP-6000 was generally well tolerated and had a safety profile consistent with that of transmucosal buprenorphine. Injection site reactions were not treatment-limiting. The most common (reported in ≥ 5% of subjects) treatment-emergent adverse events (TEAEs) reported in the active total group were constipation, headache, nausea, injection site pruritus, vomiting, increased hepatic enzyme, fatigue and injection site pain1.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Almost no data have been available on this topic to date. A recent study showed that teens in subspecialty treatment for opioid addiction were significantly less likely than adults to receive a medication. Our study was the first to comprehensively look across the health care system, including looking at adolescents and young adults diagnosed with opioid use disorder in outpatient clinics, emergency departments, and inpatient hospitals.
We had three important findings. First, looking at a large sample of 9.7 million adolescents and young adults between the age of 13 and 25 years, we found that the number of youth diagnosed with opioid use disorder increased six-fold from 2001 to 2014. This is perhaps not surprising given the national opioid crisis we know to be occurring.
Second, we found that only a minority of youth (1 in 4) received buprenorphine or naltrexone, the two medications available for opioid addiction that can be prescribed in usual medical settings. These two medications are evidence-based and their use is recommended by the American Academy of Pediatrics. Utilizing them is critical to ensure that we offer effective treatment early in the life course of addiction, which can help prevent the long-term harms of addiction.
Third, we found significant differences in who received medications. Whereas approximately 1 in 3 young adults in our study received a medication, only 1 in 10 of the 16- and 17-year-olds we studied received one, and among adolescents under 15 years of age, 1 in 67 received a medication. Females were less likely than males to receive medications, as were black youth and Hispanic youth relative to white youth.

Response: The opioid crisis is affecting the entire nation, but not in the same way in every location. Although a number of studies have been conducted on geographic variations in the opioid epidemic, there remains a need for more information on the regional level. To help meet that need, FAIR Health consulted its database of more than 23 billion privately billed healthcare claims, the largest such repository in the country. Focusing on the most recent complete ten-year period (2007-2016), FAIR Health examined claims data from rural and urban settings, the country’s five most populous cities (Chicago, Houston, Los Angeles, New York and Philadelphia) and the states where those cities are located.
When the term “opioid-related diagnoses” is used in this study, it refers to opioid abuse, opioid dependence, heroin overdose and opioid overdose (i.e., overdose of opioids excluding heroin).

Response: The heroin epidemic, which has left virtually no part of American society unscathed, can be viewed as an illness. Unlike some illnesses, however, it was largely manufactured by stakeholders in the healthcare system, wittingly or unwittingly.
The main finding, that heroin addiction costs us just over $50 billion per year, is likely a conservative estimate.

Response: The US opioid epidemic is leading to an increase in the US drug-injecting population, which also increases the risks of HIV transmission. It is critical to public health that the US invests in a coherent and cost-effective suite of HIV prevention programs. In our model-based analysis, we considered programs that have the potential both to prevent HIV and to improve long-term health outcomes for people who inject drugs. Specifically, we evaluated opioid agonist therapy, which reduces the frequency of injection; needle and syringe exchange programs, which reduce the frequency of injecting equipment sharing; enhanced HIV screening and antiretroviral therapy programs, which virally suppress individuals and decrease downstream transmission; and oral HIV pre-exposure prophylaxis (PrEP), which is taken by an uninfected individual and lowers the risk of infection.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The opioid epidemic has received tremendous attention in recent years, but most of the focus has been on chronic pain, opioid abuse and overdose. Far less attention has been paid to the importance of acute care prescribing (e.g. surgical pain) in patients that are not chronic opioid users.
We found that 5-6% of patients not using opioids prior to surgery continued to fill prescriptions for opioids long after what would be considered normal surgical recovery. Moreover, the rates of new chronic use did not differ between patients having major and minor surgeries, suggesting that patients continue to use these pain medications for something other than simply pain from surgery. Building on other work by our group, and the few additional studies done on the topic to date, these data suggest that pain medications written for surgery are a major cause of new chronic opioid use for millions of Americans each year.

MedicalResearch.com: What is the background for this study?
Response: Opioid abuse in chronic pain patients is a major public health issue, with rapidly increasing addiction rates and deaths from unintentional overdose more than quadrupling since 1999. Just in the last year alone according to the CDC, synthetic opioid deaths have increased 72%. As a practicing interventional pain specialist, I am confronted with the challenge of assessing patient risk for opioids as I evaluate multi-modal approaches to effective pain management. Existing tools are inadequate, as they either rely on a urine toxicology test to evaluate a patient’s current potential substance abuse as a predictor of future abuse, or on a patient’s honesty to fill out a questionnaire. We know that many patients who are not currently abusing illicit drugs or misusing prescription medications can develop prescription opioid tolerance, dependence, or abuse—especially with prolonged opioid therapy. Furthermore, we know that patients who are looking to abuse medications or divert those prescriptions will obviously lie on questionnaires.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The opioid epidemic has received considerable attention, but most of the focus has been on chronic pain and primary care. However, surgeons prescribe ~40% of the opioids in the US, and little attention has been given to the importance of prescribing after surgery.
In this study, we found that among patients not using opioids in the year prior to surgery, ~6% of patients continued to use opioids long after what would be considered normal surgical recovery. Furthermore, there was no difference between patients undergoing minor and major surgeries, thereby suggesting that some patients continue to use opioids for reasons other than pain related to surgery.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The background for this exhibit stemmed from the growing problem of prescription opioid abuse in the United States. As we saw this issue developing, we aimed to investigate the history behind this epidemic, what information we have now to fight it, and what information we need in the future to improve care our patients.
Our main findings for each of those aims are the following:
1) It would appear that a large push at the end of the last century led to a lower threshold to prescribe opiates in the effort to control pain, leading to the current opioid epidemic
2) Mulitmodal methods of pain control and the expanding skill of regional anesthesia can be used to help decrease narcotic use and thus limit exposure to narcotics, and
3) Future research needs to focus on the psychologic aspect of patients' ability to manage pain and we should strive to be able to categorize patients in order to create an individualized pain management protocol which will most effectively manage pain.

Response: There have been large increases in opioid-related adverse events over the past decade. The goal of our study was to examine the extent to which these increases may have been driven by combined use of opioids and benzodiazepines, a combination that is known to be potentially risky. Overall, we found that the combined use of opioids and benzodiazepines nearly doubled (80% increase) between 2001 and 2013, and that opioid users who also used benzodiazepines were at a higher risk of an opioid-related adverse event. Indeed, our results suggest eliminating the combined use of opioids and benzodiazepines could have reduced the population risk of an opioid-related adverse event by 15%.

Response: In 2001 Canada become one of the first nations to develop a federally regulated program to allow access to cannabis for medical purposes with the launch of the Marihuana Medical Access Regulations (MMAR). The program has undergone numerous convolutions, culminating in the establishment by Health Canada of the Marihuana for Medical Purposes Regulations (MMPR) in 2014, which was replaced by the Access to Cannabis for Medical Purposes (ACMPR) in 2016.
One of the primary changes in the new program(s) has been to move from a single Licensed Producer (LP) of cannabis to multiple large-scale Licensed Producers. This is the first comprehensive survey of patients enrolled in the MMPR/ACMPR, and with 271 complete responses, it’s the largest survey of federally-authorized medical cannabis patients to date.

MedicalResearch.com: What is the background for this study?
Response: In most high-income countries, premature death rates have been declining, due to the overwhelming successes of public health efforts to prevent and treat chronic disease. The US is a major outlier, where death rates overall have plateaued, or even increased, as reported recently by our sister agency, the Centers for Disease Control and Prevention. Of particular concern are recent reports of increasing death rates among Americans during mid-life.
To expand upon prior findings, we focused on premature death, which we defined as death occurring between the ages of 25 and 64. We examined finely detailed death certificate data for the entire U.S. population and described changes in death rates during 1999-2014 by cause of death, sex, race, ethnicity, and geography. To provide context to our findings, we compared trends in death rates in the U.S. to England and Wales and Canada.

Response: Our country is dealing with a devastating epidemic of opioid misuse and overdose that affects individuals, families and communities. We have long known that sharing needles and syringes is an incredibly efficient route for HIV, hepatitis and other infections to spread.
Yet, about 10% of annual HIV diagnoses in the United States occur among people who inject drugs, and there are clusters of hepatitis C infections across the country. These infections can be prevented when people who inject drugs use sterile needles, syringes and other injection equipment. One of the main findings of this study is that use of syringe services programs (SSPs) has increased substantially during the past decade, but most people who inject drugs still don’t always use sterile needles.
The analysis finds that more than half (54%) of people who inject drugs in 22 cities with a high number of HIV cases reported in 2015 they used an SSP in the past year, compared to only about one-third (36%) in 2005. Although syringe services program use has increased, findings indicate that too few people who inject drugs use only sterile needles. One in three (33%) reported in 2015 that they had shared a needle within the past year – about the same percentage that reported sharing a decade ago (36% in 2005).
The report also highlights some successes in HIV prevention among African Americans and Latinos who inject drugs, as well as concerning trends in whites who inject drugs. From our study of 22 urban areas, it appears that fewer African Americans are injecting drugs. However, it also appears there has been an increase in white Americans injecting drugs.
