Men and Women Use Different Biological Systems to Reduce Pain

In a new study evaluating meditation for chronic lower back pain, researchers at University of California San Diego School of Medicine have discovered that men and women utilise different biological systems to relieve pain. While men relieve pain by releasing endogenous opioids, the body’s natural painkillers, women rely instead on other, non-opioid based pathways. The study was published in PNAS Nexus.

Synthetic opioid drugs, such as morphine and fentanyl, are the most powerful class of painkilling drugs available. Women are known to respond poorly to opioid therapies, which use synthetic opioid molecules to bind to the same receptors as naturally-occurring endogenous opioids. This aspect of opioid drugs helps explain why they are so powerful as painkillers, but also why they carry a significant risk of dependence and addiction.

“Dependence develops because people start taking more opioids when their original dosage stops working,” said Fadel Zeidan, PhD, professor of anaesthesiology and Endowed Professor in Empathy and Compassion Research at UC San Diego Sanford Institute for Empathy and Compassion. “Although speculative, our findings suggest that maybe one reason that females are more likely to become addicted to opioids is that they’re biologically less responsive to them and need to take more to experience any pain relief.”

The study combined data from two clinical trials involving a total of 98 participants, including both healthy individuals and those diagnosed with chronic lower back pain. Participants underwent a meditation training program, then practiced meditation while receiving either placebo or a high-dose of naloxone, a drug that stops both synthetic and endogenous opioids from working. At the same time, they experienced a very painful but harmless heat stimulus to the back of the leg. The researchers measured and compared how much pain relief was experienced from meditation when the opioid system was blocked versus when it was intact.

The study found:

  • Blocking the opioid system with naloxone inhibited meditation-based pain relief in men, suggesting that men rely on endogenous opioids to reduce pain.
  • Naloxone increased meditation-based pain relief in women, suggesting that women rely on non-opioid mechanisms to reduce pain.
  • In both men and women, people with chronic pain experienced more pain relief from meditation than healthy participants.

“These results underscore the need for more sex-specific pain therapies, because many of the treatments we use don’t work nearly as well for women as they do for men,” said Zeidan.

The researchers conclude that by tailoring pain treatment to an individual’s sex, it may be possible to improve patient outcomes and reduce the reliance on and misuse of opioids.

“There are clear disparities in how pain is managed between men and women, but we haven’t seen a clear biological difference in the use of their endogenous systems before now,” said Zeidan. “This study provides the first clear evidence that sex-based differences in pain processing are real and need to be taken more seriously when developing and prescribing treatment for pain.”

Many Youths Continue to Take Post-surgery Opioids for Months

On By ModernMedia

A multi-institutional study found that 1 in 6 youths fill an opioid prescription prior to surgery, and 3% of patients were still filling opioid prescriptions three to six months after surgery, indicating persistent opioid use and possible opioid dependence. The study underscores that more guidance is needed to steer clinicians away from prescribing opioids when they are not likely to be needed and recognising patient-specific risk factors for persistent opioid use. The findings were recently published by the journal JAMA Network Open.

Approximately 1.4 million youths undergo surgery in the United States each year, and there is concern that they remain highly susceptible to opioid-related harms. While significant strides have been made in reducing prescriptions for opioids, it is important for clinicians to consider adolescent patients who may be at risk for developing an addiction to opioids due to a range of genetic, neurobiological and social vulnerabilities.  Prior to this study, little was known about risks for persistent opioid use among adolescents and the timing of initial and refill of opioid prescriptions.

“While prior analyses have shown a decline in opioid prescriptions in general, following surgical opioid prescribing recommendations remains a critical issue, especially for adolescents who are more inclined to engage in risk-taking behaviour,” said first study author Tori N. Sutherland, MD, MPH, an attending anaesthesiologist at Children’s Hospital of Philadelphia. “Our study found that these patients are still filling prescriptions that are either not recommended or are in excess of what they may need. They are also filling prescriptions up to two weeks before surgeries not associated with severe pre-operative pain, putting young patients at risk for developing persistent use throughout their lives as they transition into adulthood.”

Using a national insurance database of privately insured patients, the researchers looked at patients between 11 and 20 who underwent 22 surgical procedures that were either common or associated with severe postoperative pain requiring opioids for initial pain management. The patients had not taken opioids prior to their surgeries.

Of more than 100 000 patients, 46 951 (46.9%) patients filled a prescription for opioids, and 7587 (16.2%) of those had a prescription filled up to two weeks prior to surgery for procedures unlikely to be associated with severe preoperative pain. In this group, 6467 (13.8%) patients filled a second prescription for opioids, and 1216 (3.0%) patients filled prescriptions between 91 and 180 days after their surgical procedure.

One of the most important findings was that severe pain following a surgical procedure was not associated with persistent opioid use.  However, patients with pre-existing chronic pain, who often underwent procedures associated with mild or moderate pain that could be managed with non-opioid medications, had increased odds of developing persistent opioid use.

“We believe this study underscores the need for establishing a standard of care for patients who undergo these procedures,” said senior study author Scott Hadland, MD, MPH, Chief of Adolescent and Young Adult Medicine at Mass General for Children and Associate Professor of Pediatrics at Harvard Medical School. “Effective pain management is critical and sometimes require opioids, but clinicians also need to make sure they are doing everything possible not to further contribute to the opioid addiction crisis, particularly with young patients.”

A Handful of Procedures Account for Large Share of Post-surgical Opioids

On By ModernMedia

A handful of common surgical procedures account for large shares of all opioids dispensed after surgery in children and adults, according to two studies recently published by researchers at the University of Michigan.

The studies, published this week in Pediatrics and JAMA Network Open, report that the top three procedures for children ages 0–11 account for 59% of opioids dispensed after surgery (tonsillectomies and adenoidectomies 50%, upper extremity fractures 5% and removal of deep implants 4%). Among those ages 12–21, the top three procedures account for about a third of post-surgery opioid prescriptions (tonsillectomies and adenoidectomies 13%, knee arthroscopies 13% and caesarean deliveries 8%).

For adults ages 18–44, C-sections account for the highest share of opioids dispensed post-surgery (19%), followed by hysterectomies (7%) and knee arthroscopies (6%). Among those ages 45-64, four of the top five procedures were orthopaedic procedures, collectively accounting for 27% of total opioid prescriptions dispensed after surgery.

“Our findings suggest that surgical opioid prescribing is highly concentrated among a small group of procedures. Efforts to ensure safe and appropriate surgical opioid prescribing should focus on these procedures,” said Kao-Ping Chua, lead author of the study in Pediatrics, assistant professor at the U-M Medical School and School of Public Health, and co-director of the Research and Data Domain at the U-M Opioid Research Institute.

To conduct the study, the researchers developed an algorithm to identify 1082 major surgical procedures using procedure codes, a medical classification tool used to identify specific surgical, medical or diagnostic interventions. The algorithm was then applied to identify privately and publicly insured children and adults undergoing surgery from Dec. 1, 2020 through Nov. 30, 2021.

The information was organized through a novel system developed by the study team, which allowed them to connect different sets of data that had previously been seen as unrelated. This new method allows for improved comparability and contrast, according to lead investigators.

In addition to determining which procedures accounted for the highest shares of opioids, the researchers also examined the size of opioid prescriptions for each procedure. For many procedures, prescriptions were far larger than the amount patients typically need for a particular procedure.

“Our findings suggest that there are important opportunities to reduce surgical opioid prescribing without compromising pain control,” said Dominic Alessio-Bilowus, lead author of the paper focused on adults published in JAMA Network Open and a medical student at Wayne State University who just completed a research year at U-M.

Patients Are Now Getting Fewer Post-op Opioids, but Decline is Slowing

On By ModernMedia

Post-surgery pain relief has shifted away from opioid-containing medications over the past seven years, but the downward trend has slowed since 2020, a new University of Michigan study shows.

Overall, the rate of surgery-related opioid prescriptions dropped by 36% from 2016 to the end of 2022, and the average amount of opioids in those prescriptions dropped by 46%, the study of pharmacy data finds.

That combination of declines means that the total amount of opioids dispensed to surgical patients in late 2022 was 66% lower compared with early 2016, according to the findings published in JAMA Network Open.

But the rate of decline was much faster before the pandemic, the researchers report after comparing surgical opioid patterns before and after 2020.

That’s even after they took into account the unusual circumstances of spring 2020, when most elective surgery temporarily stopped to free up hospital capacity for COVID-19 patients and reduce unnecessary exposure to the SARS-CoV-2 virus.

Even with the overall declines, American surgery patients in late 2022 still received the equivalent of 44 5-milligram pills of hydrocodone from pharmacies after their operations on average.

That’s far higher than what patients need for most procedures.

“These data suggest surgical teams have substantially reduced opioid prescribing, but also suggest that efforts to right-size opioid prescriptions after surgery must continue,” said Kao-Ping Chua, M.D., Ph.D., the senior author of the new study and an assistant professor of pediatrics at U-M. He worked with first author and former U-M research assistant Jason Zhang, who is now in medical school at Northwestern University.

The researchers also find that some types of surgeons have reduced the amount of opioids dispensed to patients more than others.

For instance, reductions were particularly large in cardiothoracic surgery and ophthalmology.

Orthopedic surgeons still account for more than half of all surgical opioids dispensed to American patients, even as the rate and size of prescriptions filled by their patients dropped.

Right-sizing prescribing

The authors note that surgeons should not strive to eliminate opioid prescribing altogether.

“The goal should be to ensure that opioids are only prescribed when necessary, and that the amount of opioids prescribed matches the amount that patients need,” said Zhang.

“Achieving these goals could help reduce the risk of opioid misuse, persistent opioid use, and diversion of pills to other people besides the patient.”

The potential for accidental exposure to opioids by others in the household, and interactions between opioids and other substances including alcohol and prescription drugs, are other reasons to focus on non-opioid surgical pain care.

Chua and colleagues have studied procedure-related opioid prescribing multiple times, including a recent study showing that the reduction in the rate of dental opioid prescribing has similarly slowed in recent years.

Surgical organisations and the Centers for Disease Control and Prevention have advised surgeons to rely less on opioid-based acute pain relief for their patients since the mid-2010s.

But no studies have examined surgical opioid prescribing trends using pandemic-era data.

The new study is based on data from a company called IQVIA that tracks prescriptions dispensed at 92% of US pharmacies.

No Increase in Post-surgical Pain Seen with Opioid Limits

On By ModernMedia

Concerns that surgery patients would have a more difficult recovery if their doctors had to abide by a five-day limit on opioid pain medication prescriptions did not play out as expected, finds a study published in JAMA Health Forum.

Instead, the University of Michigan-led researchers found that , after the largest insurer in that US state put the limit in place, patient-reported pain levels and satisfaction didn’t change at all for adults who had their appendix or gallbladder removed, a hernia repaired, a hysterectomy or other common operations.

At the same time, the amount of opioid pain medication patients covered by that insurer received dropped immediately after the limit went into effect. On average, patients having these operations received about three fewer opioid-containing pills.

The study, which merges two statewide databases on patients covered by Blue Cross Blue Shield of Michigan, is the first large study to evaluate whether opioid prescribing limits change patient experience after surgery.

Measuring the impact of limits from patients’ perspectives

The BCBSM limit of five days’ supply, which went into effect in early 2018, is even stricter than the seven-days’ supply limit put in place a few months later by the state of Michigan.

Other major insurers and states have also implemented limits, most of which allow are seven-day limits.

Limits are designed to reduce the risk of long-term opioid use and opioid use disorder, as well as to reduce the risk of accidental overdose and the risk of unauthorized use of leftover pills.

“Opioid prescribing limits are now everywhere, so understanding their effects is crucial,” said lead author Kao-Ping Chua, MD, PhD.

“We know these limits can reduce opioid prescribing, but it hasn’t been clear until now whether they can do so without worsening patient experience.”

He noted that even the 15% of patients who had been taking opioids for other reasons before having their operations showed neither an increase in pain nor a decrease in satisfaction after the limit was put in place, even though opioid prescribing for these patients decreased.

That decrease was actually contrary to the intent of the limit, which was only designed to reduce prescribing to patients who hadn’t taken opioids recently.

How the study was done

For the new study, Chua and colleagues used data from the Michigan Surgical Quality Collaborative, which collects data on patients having common operations at 70 Michigan hospitals. The MSQC surveys patients about their pain, level of satisfaction and level of regret after their operations.

The team paired anonymized MSQC data with data on controlled substance prescription fills from Michigan state’s prescription drug monitoring programme, called MAPS.

In all, they were able to look at opioid prescribing and patient experience data from 1,323 BCBSM patients who had common operations in the 13 months before the five-day limit went into effect, and 4,722 patients who had operations in the 20 months after the limit went into effect.

About 86% of both groups were non-Hispanic white, patients’ average age was just under 49,  and just under a quarter of both groups had their operations on an emergency or urgent basis. Just under half were admitted to the hospital for at least one night.

About 27% of both groups had their gallbladders taken out laparoscopically, and a similar percentage had minor hernia repairs.

About 10% had an appendectomy done laparoscopically, and a similar percentage had laparoscopic hysterectomies.

The rest had more invasive procedures, like open hysterectomies major hernia repairs, or colon removal. 

The percentage of prescribers who prescribed opioids to their patients having these operations did not change, but the percentage of patients who filled a prescription for an opioid did, possibly because pharmacists rejected prescriptions that weren’t compliant with the BCBSM limit, Chua speculates.

Jennifer Waljee, MD, MPH, MS, senior author of the study, notes that the MSQC database doesn’t include all types of procedures, such as knee replacements and spine surgery, which typically require larger postoperative opioid prescriptions because of their associated pain.

She indicated that it’s important to understand the impact of opioid prescribing limits on the experiences of such patients, because limits have the most potential to worsen pain for these individuals. 

“Opioid prescribing limits may not worsen patient experience for common, less-invasive procedures like those we studied, because opioid prescriptions for most of these procedures were already under the maximum allowed by limits.

“But this may not be the case for painful operations where opioid prescribing was suddenly cut from an 8- to 10-day supply to a 5-day supply,” said Waljee.

She added, “The message of this study is not that we can simply go to five days’ supply across the board for operations.

“We need to understand the effects of these limits across a broad range of procedures and patients given how much pain needs vary in order to right size prescribing to patient need without resulting in additional harms.”

Avoiding Addiction and Hallucination in the Quest for New Anaesthetics

On By ModernMedia

Strategies to treat pain without triggering dangerous side effects such as euphoria and addiction have proven elusive. For decades, scientists have attempted to develop drugs that selectively activate one type of opioid receptor to treat pain while not activating another type of opioid receptor linked to addiction. Unfortunately, those compounds can cause a different unwanted effect: hallucinations. But a new study published in the journal Nature has identified a potential route to pain relief that neither triggers addiction nor activates the pathway that causes hallucinations.

Painkilling drugs such as morphine and oxycodone, as well as illegal street drugs such as heroin and fentanyl, activate what are known as mu opioid receptors on nerve cells. Those receptors relieve pain but also cause euphoria, contributing to addiction. An alternative strategy is to target another opioid receptor, called the kappa opioid receptor. Scientists attempting to make drugs that target only the kappa receptor have found that they also effectively relieve pain, but they can be associated with other side effects such as hallucinations.

Research led by Washington University School of Medicine in St. Louis has identified the potential mechanisms behind such hallucinations, with the goal of developing painkillers without this side effect. Using electron microscopes, the researchers identified the way that a natural compound related to the salvia plant selectively binds only to the kappa receptor but then causes hallucinations.

“Since 2002, scientists have been trying to learn how this small molecule causes hallucinations through kappa receptors,” said principal investigator Tao Che, PhD, an assistant professor of anesthesiology. “We determined how it binds to the receptor and activates potential hallucinogenic pathways, but we also found that other binding sites on the kappa receptor don’t lead to hallucinations.”

Developing new drugs to target these other kappa receptor binding sites may relieve pain without either the addictive problems associated with older opioids or the hallucinations associated with the existing drugs that selectively target the kappa opioid receptor.

Targeting the kappa receptor to block pain without hallucinations would be an important step forward, according to Che, because opioid drugs that interact with the mu opioid receptor have led to the current opioid epidemic, causing more than 100 000 overdose deaths in the US in 2021.

“Opioids, especially synthetic opioids such as fentanyl, have contributed to far too many overdose deaths,” Che said. “There’s no doubt we need safer pain-relieving drugs.”

Che’s team, led by first author Jianming Han, PhD, a postdoctoral research associate in Che’s laboratory, found that a class of signaling proteins called G proteins cause the kappa opioid receptor to activate several different pathways.

“There are seven G proteins linked to the kappa receptor, and although they are very similar to each other, the differences between the proteins may help explain why some compounds can cause side effects such as hallucinations,” Han said. “By learning how each of the proteins binds to the kappa receptor, we expect to find ways to activate that receptor without causing hallucinations.”

The function of the G proteins has largely been unclear until now, particularly the protein that activates the pathway lined to hallucinations.

“All of these proteins are similar to one another, but the specific protein subtypes that bind to the kappa receptor determine which pathways will be activated,” Che said. “We have found that the hallucinogenic drugs can preferentially activate one specific G protein but not other, related G proteins, suggesting that beneficial effects such as pain relief can be separated from side effects such as hallucinations. So we expect it will be possible to find therapeutics that activate the kappa receptor to kill pain without also activating the specific pathway that causes hallucinations.”

US CDC Pivots to a Less Rigid Approach to Opioid Prescription

On By ModernMedia

The US Centers for Disease Control have released new opioid prescribing guidelines that do not promote strict thresholds for dose and duration of pain medications. The new guidelines, which update and replace the controversial 2016 guidelines, are published in Morbidity and Mortality Weekly Report.

The previous guidelines had been interpreted as imposing strict opioid dose and duration limits and was misapplied by some organisations, leading to a clarification being released in 2019. Other organisations, such as the European Pain Federation, had stated that overly strict guidelines for their own countries were hampering effective pain management.

The 2022 recommendations are voluntary and give clinicians and patients flexibility to support individual care, said Christopher Jones, PharmD, DrPH, MPH, acting director of CDC’s National Center for Injury Prevention and Control in a press briefing. He stressed that they should not be used as a inflexible rule, or applied as a rigid standard of care, or replace clinical judgement on personalised treatment.

“Patients with pain should receive compassionate, safe, and effective pain care,” Jones stated. “We want clinicians and patients to have the information they need to weigh the benefits of different approaches to pain care, with the goal of helping people reduce their pain and improve their quality of life.”

The guidance covers four key areas: opioids initiation for pain, opioid and dosage selection, deciding prescription duration and conducting follow-up, and assessing risk and potential harms of opioids. It also suggests that clinicians work with patients to incorporate plans to mitigate risks, including offering naloxone.

The document indicates opioids should not be considered as first-line or routine therapy for subacute or chronic pain, and points out that, for many kinds of acute pain, non-opioid therapies are often better choices.

“For patients receiving opioids for 1 to 3 months (the timeframe for subacute pain), the 2022 guideline recommends that clinicians avoid continuing opioid treatment without carefully reassessing treatment goals, benefits, and risks in order to prevent unintentional initiation of long-term opioid therapy,” noted Deborah Dowell, MD, MPH and colleagues in a commentary published in the New England Journal of Medicine.

For chronic pain, clinicians should make maximal use of non-opioid therapies and consider initiating opioid therapy only if pain reduction benefits outweigh the risk, Dowell and colleagues noted. When needed, clinicians should initiate opioids at the minimum effective dose, assess risks and benefits before increasing dosage, and avoid raising dosage above levels likely to yield diminishing returns, they added.

The new guideline offers tips for tapering opioids when warranted, but is not intended to lead to rapid opioid tapering or discontinuation, Jones noted. The recommendations do not apply to sickle cell disease-related pain, cancer pain, and palliative or end-of-life care.

The 2022 document incorporated public feedback since the new version was first proposed in February, including patients discussing their experiences with pain or opioid addiction and barriers to pain care.

“The science on pain care has advanced over the past 6 years. During this time, CDC has also learned more from people living with pain, their caregivers, and their clinicians,” said Dowell in a statement. “We’ve been able to improve and expand our recommendations by incorporating new data with a better understanding of people’s lived experiences and the challenges they face when managing pain and pain care.”

Fentanyl Induces Autism-like Behaviours in Young Mice

On By ModernMedia

Fentanyl is one of the most commonly used analgesics in the hospital and, in rodents, may have lasting sensorimotor and behavioural impacts. A study published in the British Journal of Anaesthesia has shown that fentanyl can induce changes similar to autism-like behaviours in young mice.

Fentanyl, a mu-opioid receptor agonist, is a potent synthetic opioid, which, similar to morphine, produces analgesia but is 50 to 100 times more potent. A dose of only 100 micrograms can produce equivalent analgesia to approximately 10mg of morphine. However, fentanyl exhibits vastly different properties and pharmacokinetics. Clinically, its most common use is as a sedative in intubated patients and severe cases of pain in patients with renal failure due to its primarily hepatic elimination. Fentanyl’s side effects are similar to those of heroin.

However, whether the use of fentanyl is associated with the development of autism is not known. An animal study led by investigators at Massachusetts General Hospital (MGH), Shanghai 10th People’s Hospital, and the University of Pennsylvania e. The findings are

Research by other groups has shown that N-methyl-D-aspartate receptor dysfunction contributes to autism. Variations in Grin2a and Grin2b, the genes encoding GluN2A and GluN2B subunits of N-methyl-D-aspartate receptor, are associated with autism. In addition, the anterior cingulate cortex of the brain is affected in autism.

In this current study, the research team reported that fentanyl induces autism-like behaviors in young male and female mice via activating the mu-opioid receptor in the anterior cingulate cortex. Further, these fentanyl-induced autism-like behaviors appear partially due to the hypermethylation-mediated reduction of Grin2b expression in the anterior cingulate cortex of mice.

“Because the anterior cingulate cortex is a hub for mediating social information, we focused on the expression of Grin2b in that area,” says Yuan Shen, MD, PhD, the paper’s senior author and a professor of Psychiatry at Shanghai 10th People’s Hospital. “We found fentanyl decreased expression of Grin2b in the anterior cingulate cortex. The overexpression of Grin2b prevents fentanyl-induced autism-like behavior in the mice. These findings suggest a potential mechanism to prevent or treat the autism-like behavior,” says Shen.

The group used an open field test (in which a mouse can walk inside a box) and an elevated plus-maze (in which a mouse can walk on an elevated platform) to observe the anxiety and stereotyped behaviours of mice. Using a three-chamber social preference test (where a mouse can interact with another mouse), they also assessed potential social deficits. “We used these tests because impaired social interaction, stereotyped behaviours, and anxiety are the key feature of autism-like behaviours in mice,” said Zhihao Sheng, co-first author of the paper. Sheng is a graduate student at Shanghai 10th People’s Hospital.

“However, the changes of mice in these behavioral tests do not equal autism in humans. These behavioral tests are only used to study the autism-like behaviors in mice because they can demonstrate certain features of behavior changes similar to the manifestation of autism,” said co-first author Qidong Liu, PhD, assistant professor at Shanghai 10th People’s Hospital.

Co-senior author Zhongcong Xie, MD, PhD, added: “There is no current evidence that fentanyl is associated with a similar effect in humans and the outcome of the animal study is not an indication to avoid fentanyl in clinical anesthesia. However, the outcome will promote further research, including clinical investigations, to determine the potential neurobehavioral influence of opioids on brain development.”

Opioid Misuse in Young Sarcoma Patients

Nearly a quarter of young patients prescribed opioids while being treated for sarcoma continue to use opioids after treatment is completed according to findings published in CANCER, highlighting the need for safe deprescribing.

Individuals with sarcoma, a type of cancer in the bones or soft tissues, often develop damaged and fractured bones and undergo major surgical operations, and physicians may prescribe opioids for pain management. It was not clear whether doing so raises the risk for opioid misuse and overdose in these young patients. 

Melissa Beauchemin, PhD, RN, CPNP-PC, CPON, of Columbia University School of Nursing, and her colleagues sought to determine the rate of new persistent opioid use among adolescents and young adults treated for sarcoma. Persistent opioid use was defined as at least two opioid prescriptions in the 12 months after treatment was completed.  

The team drew from a large insurance claims database to analyse information on patients aged 10–26 years old who had not received prior opioids and who were diagnosed with sarcoma between 2008 and 2016.  

Among the 938 patients in the analysis, 64% received opioid prescriptions during treatment. After completing cancer therapy, 14% of patients overall and 23% of those who used opioids during treatment continued to use opioids and met the criteria for new persistent use. Being covered by Medicaid versus commercial insurance, having bone tumours versus soft tissue tumours, and receiving concurrent lorazepam (often prescribe to treat anxiety and sleeping problems) were associated with persistent opioid use. 

“Adolescents and young adults are a vulnerable population because they have benefitted less than younger and older cancer patients from recent advances. These results highlight the need to monitor young patients with sarcoma for posttreatment opioid use, given the potential negative impacts of long-term opioid use, including misuse and overdose,” said Dr Beauchemin. “Age- and developmentally appropriate strategies to effectively manage pain while minimising opioid exposure are urgently needed.” 

Dr Beauchemin stressed that for young people needing opioids for effective pain management, early and safe discontinuation of opioids should be prioritised. “Further, there is a critical need for clinical practice guidelines to support clinical decision making to safely and effectively manage pain specifically for adolescents and young adults with cancer,” she said.

Carrying Naloxone in EDs Could Save Lives

On By ModernMedia

In a study published in JAMA Network Open, researchers found that after a visit to the ED, many opioid overdose patients carried naloxone, which helps reverse opioid overdoses, which could save their lives in the event of a future overdose.

About 70% of current overdose deaths in the US involve opioids, which means that many of them could be prevented with naloxone. Naloxone is an opioid antagonist, blocking the effect of opioids in overdoses and able to save lives when used in time. It is easy to carry and use, and studies have demonstrated that laypeople can administer it safely and effectively to reverse overdoses.

However the people most likely to witness an overdose, including opioid users and their friends and relatives, may not be able to easily obtain naloxone. Strategies are needed to increase uptake, carrying, and administration of naloxone, especially among at-risk individuals in the community who may not be engaged in routine health care or with community naloxone distribution efforts.

Many at-risk individuals find themselves in the emergency departments (ED), either because of an overdose or other complications of substance use. The Perelman School of Medicine’s Anish Agarwal, an assistant professor of emergency medicine, and Margaret Lowenstein, an assistant professor of medicine, recently examined the potential for ED visits as a critical, reachable moment to engage high-risk individuals in overdose prevention. The team reached out to at-risk patients prescribed naloxone in the ED to understand whether they had obtained their naloxone during or after their ED visit, whether they were carrying it, and their plans to carry it in the future.

The survey asked patients about their experiences and perceptions following the ED encounter related to accessing, using, and carrying naloxone. Most of the patients did not carry naloxone prior to their ED, yet over a third reported having a personal history of an overdose requiring naloxone, and more than a quarter had used naloxone to reverse an overdose for another person in the past. Approximately half of the patients said that they were carrying naloxone after their ED visit, and two-thirds planned to continue carrying. And of patients not carrying naloxone prior to their ED visit, 54% reported a plan to continue carrying it in the future.
