Non-transport after Prehospital Naloxone Administration Is Associated with Higher Risk of Subsequent Non-fatal Overdose.

Objective: U.S. opioid overdoses increased nearly sixfold from 1999 to 2018, and greater than 1% of all emergency medical services (EMS) encounters now involve naloxone administration. While "treat and release" protocols may have low short-term mortality, the risk of subsequent non-fatal overdoses is not known. This study compares the risk of repeat overdose encounters between patients transported to an emergency department (ED) and those who refused transport after prehospital naloxone administration. Methods: All EMS charts within a large single-tier fire-based urban EMS system between January 1 and August 31, 2018 were reviewed if either naloxone administration or a clinical impression related to opioid overdose was documented. Charts were excluded if there was no documented evidence of an opioid toxidrome (respiratory depression or altered mental status), if there was another clear explanation for the symptoms (e.g., hypoglycemia), or if naloxone was not administered. Ten percent of charts were reviewed by a second author to assess reliability. Cox regression (survival analysis) was used to estimate the risk of a subsequent EMS encounter with naloxone administration following an index encounter with naloxone administration. Results: Of the 2143 charts reviewed, 1311 unique patients with 1600 overdose encounters involving naloxone administration were identified. Inter-rater reliability for chart inclusion was strong [κ = 0.83 (95% CI: 0.72-0.90)]. Police/bystanders administered naloxone in 208/1600 (13.0%) encounters. A substantial proportion of encounters resulted in transport refusal (674/1600, 42.1%). The final Cox model included only refusal vs. acceptance of transport to an ED during the index EMS encounter. Patient age, gender, and naloxone administration prior to EMS arrival were not statistically significant in univariate or multivariable analyses, nor were they significant confounders. Refusal of transport was associated with a hazard ratio of 1.66 (95% CI: 1.23-2.23) for subsequent EMS encounters with naloxone administration. Conclusions: Non-transport after prehospital naloxone administration is associated with an increased risk of subsequent non-fatal overdose requiring EMS intervention. Limitations include the use of a single EMS agency as patients may have had uncaptured overdose encounters in neighboring municipalities.

Development and implementation of a novel Web-based gaming application to enhance emergency medical technician knowledge in low- and middle-income countries.

BACKGROUND: Increasing access to high-quality emergency and prehospital care is an important priority in low- and middle-income countries (LMICs). However, ensuring that emergency medical technicians (EMTs) maintain their clinical knowledge and proficiency with procedural skills is challenging, as continuing education requirements are still being introduced, and clinical instructional efforts need strengthening. We describe the development and implementation of an innovative asynchronous learning tool for EMTs in the form of a Web-based trivia game. METHODS: Over 500 case-based multiple-choice questions (covering 10 essential prehospital content areas) were created by experts in prehospital education, piloted with EMT educators from LMICs, and delivered to EMTs through a Web-based quiz game platform over a 12-week period. We enrolled 252 participants from nine countries. RESULTS: Thirty-two participants (12.7%) completed the entire 12-week game. Participants who completed the game were administered a survey with a 100% response rate. Ninety-three percent of participants used their mobile phone to access the game. Overall, participants reported that the interface was easy to use (93.8% agreed or strongly agreed), the game improved their knowledge (100% agreed or strongly agreed), and they felt better prepared for their jobs (100% agreed or strongly agreed). The primary motivators for participation were improving patient care (37.5%) and being recognized on the game's leaderboard (31.3%). All participants reported that they would engage in the game again (43.8% agreed and 56.3% strongly agreed) and would recommend the game to their colleagues (34.4% agreed and 65.6% strongly agreed). CONCLUSIONS: In conclusion, a quiz game targeting EMT learners from LMICs was viewed as accessible and effective by participants. Future efforts should focus on increasing retention and trialing languages in addition to English.

Prehospital emergency services screening and referral to reduce falls in community-dwelling older adults: a systematic review.

BACKGROUND: Falls represent an increasing source of geriatric morbidity and mortality. Prehospital emergency services may be uniquely suited to screen and refer subsets of high-risk older adults to fall prevention programmes. This systematic review assesses the effectiveness of such screening and referral programmes. METHODS: We searched PubMed, Embase, CINAHL, Web of Science, Scopus, the Cochrane Library and OTseeker for English-language peer-reviewed randomised trials, non-randomised trials and cohort studies evaluating prehospital fall risk screening and referral programmes for community-dwelling adults ≥60 years of age. Risk of bias was assessed using the Cochrane Collaboration's tool. Primary outcomes included the risk and rate of falling. Secondary outcomes included successful follow-up to address fall risks and adverse events. RESULTS: From 6187 unique records, 6 studies were included. Screening varied from using semistructured risk assessments to recording chief complaints. All studies were at high risk of bias. One unblinded trial of a multifactorial fall prevention programme demonstrated a 14.3% (95% CI 6.1% to 22.5%) absolute reduction in annual fall risk and a relative fall incidence of 0.45 (95% CI 0.35 to 0.58). The probability of successful follow-up varied from 9.8% to 81.0%. No studies demonstrated any attributable adverse events. CONCLUSIONS: No high-quality evidence demonstrates that prehospital services reduce falls in community-dwelling older adults. Screening by prehospital personnel using semistructured risk assessments appears feasible, but it is unclear whether this is superior to referral based on fall-related chief complaints.
