Antitussives and substance abuse

Abuse of antitussive preparations is a continuing problem in the United States and throughout the world. Illicit, exploratory, or recreational use of dextromethorphan and codeine/promethazine cough syrups is widely described. This review describes the pharmacology, clinical effects, and management of toxicity from commonly abused antitussive formulations

Preliminary Efforts Directed Toward the Detection of Craving of Illicit Substances: The iHeal Project

Many behavioral interventions, whether for the management of chronic pain, overeating, medication adherence, or substance abuse, are ineffective outside of the clinic or office environments in which they are taught. This lack of utility has spawned interest in enabling technologies that are capable of detecting changes in affective state that potentially herald a transition to risky behaviors. We have therefore undertaken the preliminary development of “iHeal”, an innovative constellation of technologies that incorporates artificial intelligence, continuous biophysical monitoring, wireless connectivity, and smartphone computation. In its fully realized form, iHeal can detect developing drug cravings; as a multimedia device, it can also intervene as the cravings develop to prevent drug use. This manuscript describes preliminary data related to the iHeal Project and our experience with its use.United States.

Federal Funding in Emergency Medicine: Demographics and Perspectives of Awardees

INTRODUCTION: Emergency physicians face multiple challenges to obtaining federal funding. The objective of this investigation was to describe the demographics of federally-funded emergency physicians and identify key challenges in obtaining funding. METHODS: We conducted a retrospective database search of the National Institutes of Health (NIH) Research Portfolio Online Reporting Tool (NIH RePORTER) to collect data regarding the distribution and characteristics of federally-funded grants awarded to emergency medicine (EM) principal investigators between 2010-2017. An electronic survey was then administered to the identified investigators to obtain additional demographic data, and information regarding their career paths, research environment, and perceived barriers to obtaining federal funding. RESULTS: We identified 219, corresponding to 51 unique, mentored career development awardees and 105 independent investigators. Sixty-two percent of investigators responded to the electronic survey. Awardees were predominantly White males, although a larger portion of the mentored awardee group was female. Greater than half of respondents reported their mentor to be outside of the field of EM. The most common awarding institution was the National Heart Lung and Blood Institute. Respondents identified barriers in finding adequate mentorship, time to gather preliminary data, and the quality of administrative support. CONCLUSION: The last five years have showed a trend toward increasing grants awarded to EM investigators; however, we identified several barriers to funding. Initiatives geared toward support and mentorship of junior faculty, particularly to females, minorities, and those in less heavily funded areas of the country are warranted

Low-energy Bluetooth for Detecting Real-world Penetrance of Bystander Naloxone Kits: A Pilot Study

Opioid overdose is a growing public health emergency in the United States. The antidote naloxone must be administered rapidly after opioid overdose to prevent death. Bystander or take-home naloxone programs distribute naloxone to opioid users and other community members to increase naloxone availability at the time of overdose. However, data describing the natural history of take- home naloxone in the hands of at-risk individuals is lacking. To understand patterns of naloxone uptake in at-risk users, we developed a smart naloxone kit that uses low-energy Bluetooth (BLE) to unobtrusively detect the transit of naloxone through a hospital campus. In this paper, we describe development of the smart naloxone kit and results from the first 10 participants in our pilot study

Oxycodone Ingestion Patterns in Acute Fracture Pain: a Pilot Study Using a Digital Pill

Background: Opioids are prescribed for acute pain as needed, but no data exists on how patients take opioids after discharge from the ED. This places the onus of dosing on the patient and contributes to variable prescribing by ED physicians. ED opioid prescriptions serve as a source for unintentional exposure and contribute to the opioid epidemic. We deployed a digital pill to measure opioid ingestion patterns in individuals discharged after acute fractures. Methods: This pilot study involved individuals without chronic opioid use (i.e. prescribed opioids \u3e 1 week) who were discharged from the ED following acute fracture. Participants were trained to use a digital pill system comprising a single pill (5 mg oxycodone tablet + radiofrequency emitter) and a hip mounted receiver. Upon contact with gastric contents, the digital pill transmitted a radio signal to the receiver, which relayed time of ingestion via cellular 3G signal in real-time to a cloud based server. Participants were instructed to take 1-2 oxycodone digital pills as needed every 8 hours for pain. Participants returned unused medication at orthopedic follow up or 1 week post discharge where any discrepancies between digital pill data and pill counts were reconciled. Results: We enrolled 10 participants (mean age 42). 50% of fractures were managed operatively and 50% were managed nonoperatively. The system recorded ingestions with 85% accuracy. Participants ingested a mean 43 mg oxycodone during the 1 week study period with dose de-escalation occurring after 24 hours. Participants ingested a mean 75.8% of their 1 week total dose in the first 72 hours. 40% of participants stopped taking opioids by 96 hours. 40% of participants remained on opioids 1 week after injury; all required operative treatment. Conclusions: This is the first study to determine opioid ingestion patterns in ED patients discharged with acute fracture pain. Participants self-tapered opioids after 24 hours, most ingestion occurred in the first 72 hours, and a substantial proportion (40%) stopped ingesting oxycodone by 96 hours. Our data shows individuals may require less opioid analgesics than previously considered for acute fracture pain. Additional studies should address ingestion patterns in other painful conditions and development of ED-based interventions to minimize outpatient opioid use while controlling pain

Crowd-Sourced Focus Groups on Twitter: 140 Characters of Research Insight

Researchers have traditionally relied on in-person focus groups to test and obtain feedback regarding behavioral and technology-based interventions for specific disease processes. An increasing generation of engaged and connected patients turn to Twitter, a popular microblogging service, to discuss health related topics. Regularly scheduled Twitter-based chats (tweetchats) can potentially function as an additional source of input and information from a diverse, global group of engaged participants. We report the first use of a “tweetchat focus group” to explore data collection issues using this methodology. The speed at which tweetchat conversations occur, coupled with the ability to pursue multiple streams of conversation both in real time and in a delayed fashion, make tweetchat data collection particularly challenging. We discuss important considerations and preparation that should be undertaken by the researchers prior to initiating a tweetchat focus group, consider facilitation challenges and issues of confidentiality.

Real-Time Mobile Detection of Drug Use with Wearable Biosensors: A Pilot Study

While reliable detection of illicit drug use is paramount to the field of addiction, current methods involving self-report and urine drug screens have substantial limitations that hinder their utility. Wearable biosensors may fill a void by providing valuable objective data regarding the timing and contexts of drug use. This is a preliminary observational study of four emergency department patients receiving parenteral opioids and one individual using cocaine in a natural environment. A portable biosensor was placed on the inner wrist of each subject, to continuously measure electrodermal activity (EDA), skin temperature, and acceleration. Data were continuously recorded for at least 5 min prior to drug administration, during administration, and for at least 30 min afterward. Overall trends in biophysiometric parameters were assessed. Injection of opioids and cocaine use were associated with rises in EDA. Cocaine injection was also associated with a decrease in skin temperature. Opioid tolerance appeared to be associated with a blunted physiologic response as measured by the biosensor. Laterality may be an important factor, as magnitude of response varied between dominant and nondominant wrists in a single patient with bilateral wrist measurements. Changes in EDA and skin temperature are temporally associated with intravenous administration of opioids and cocaine; the intensity of response, however, may vary depending on history and extent of prior use.University of Massachusetts Medical School.

Usability and Reliability of Smart Glasses for Secondary Triage During Mass Casualty Incidents

Wearable smart glasses like Google Glass provide real-time video and image transmission to remote viewers. The use of Google Glass and other Augmented Reality (AR) platforms in mass casualty incidents (MCIs) can provide incident commanders and physicians at receiving hospitals real-time data regarding injuries sustained by victims at the scene. This real-time data is critical to allocation of hospital resources prior to receiving victims of a MCI. Remote physician participation in real-time MCI care prior to victims’ hospital arrival may improve triage, and direct emergency and critical care services to those most in need. We report the use of Google Glass among first responders to transmit real-time data from a simulated MCI to allow remote physicians to complete augmented secondary triage

Intersection of chronic pain treatment and opioid analgesic misuse: causes, treatments, and policy strategies

Treating chronic pain in the context of opioid misuse can be very challenging. This paper explores the epidemiology and potential treatments for chronic pain and opioid misuse and identifies educational and regulation changes that may reduce diversion of opioid analgesics. We cover the epidemiology of chronic pain and aberrant opioid behaviors, psychosocial influences on pain, pharmacological treatments, psychological treatments, and social treatments, as well as educational and regulatory efforts being made to reduce the diversion of prescription opioids. There are a number of ongoing challenges in treating chronic pain and opioid misuse, and more research is needed to provide strong, integrated, and empirically validated treatments to reduce opioid misuse in the context of chronic pain

Digital Pills to Measure Opioid Ingestion Patterns in Emergency Department Patients With Acute Fracture Pain: A Pilot Study

BACKGROUND: Nonadherence to prescribed regimens for opioid analgesic agents contributes to increasing opioid abuse and overdose death. Opioids are frequently prescribed on an as-needed basis, placing the responsibility to determine opioid dose and frequency with the patient. There is wide variability in physician prescribing patterns because of the lack of data describing how patients actually use as-needed opioid analgesics. Digital pill systems have a radiofrequency emitter that directly measures medication ingestion events, and they provide an opportunity to discover the dose, timing, and duration of opioid therapy. OBJECTIVE: The purpose of this study was to determine the feasibility of a novel digital pill system to measure as-needed opioid ingestion patterns in patients discharged from the emergency department (ED) after an acute bony fracture. METHODS: We used a digital pill with individuals who presented to a teaching hospital ED with an acute extremity fracture. The digital pill consisted of a digital radiofrequency emitter within a standard gelatin capsule that encapsulated an oxycodone tablet. When ingested, the gastric chloride ion gradient activated the digital pill, transmitting a radiofrequency signal that was received by a hip-worn receiver, which then transmitted the ingestion data to a cloud-based server. After a brief, hands-on training session in the ED, study participants were discharged home and used the digital pill system to ingest oxycodone prescribed as needed for pain for one week. We conducted pill counts to verify digital pill data and open-ended interviews with participants at their follow-up appointment with orthopedics or at one week after enrollment in the study to determine the knowledge, attitudes, beliefs, and practices regarding digital pills. We analyzed open-ended interviews using applied thematic analysis. RESULTS: We recruited 10 study participants and recorded 96 ingestion events (87.3%, 96/110 accuracy). Study participants reported being able to operate all aspects of the digital pill system after their training. Two participants stopped using the digital pill, reporting they were in too much pain to focus on the novel technology. The digital pill system detected multiple simultaneous ingestion events by the digital pill system. Participants ingested a mean 8 (SD 5) digital pills during the study period and four participants continued on opioids at the end of the study period. After interacting with the digital pill system in the real world, participants found the system highly acceptable (80%, 8/10) and reported a willingness to continue to use a digital pill to improve medication adherence monitoring (90%, 9/10). CONCLUSIONS: The digital pill is a feasible method to measure real-time opioid ingestion patterns in individuals with acute pain and to develop real-time interventions if opioid abuse is detected. Deploying digital pills is possible through the ED with a short instructional course. Patients who used the digital pill accepted the technology
