Leveraging Body-Worn Camera Footage to Better Understand Opioid Overdoses and the Impact of Police-Administered Naloxone.

Objectives. To investigate what transpires at opioid overdoses where police administer naloxone and to identify the frequency with which concerns about police-administered naloxone are observed. Methods. We reviewed body-worn camera (BWC) footage of all incidents where a Tempe, Arizona police officer administered naloxone or was present when the Tempe Fire Medical Rescue (TFMR) administered it, from February 3, 2020 to May 7, 2021 (n = 168). We devised a detailed coding instrument and employed univariate and bivariate analysis to examine the frequency of concerns regarding police-administered naloxone. Results. Police arrived on scene before the TFMR in 73.7% of cases. In 88.6% of calls the individual was unconscious when police arrived, but 94.6% survived the overdose. The primary concerns about police-administered naloxone were rarely observed. There were no cases of improper naloxone administration or accidental opioid exposure to an officer. Aggression toward police from an overdose survivor rarely occurred (3.6%), and arrests of survivors (3.6%) and others on scene (1.2%) were infrequent. Conclusions. BWC footage provides a unique window into opioid overdoses. In Tempe, the concerns over police-administered naloxone are overstated. If results are similar elsewhere, those concerns are barriers that must be removed. (Am J Public Health. 2022;112(9):1326-1332. https://doi.org/10.2105/AJPH.2022.306918).

Moving Beyond Narcan: A Police, Social Service, and Researcher Collaborative Response to the Opioid Crisis.

The opioid crisis is the most persistent, long-term public health emergency facing the United States, and available evidence suggests the crisis has worsened during the COVID-19 global pandemic. Naloxone is an effective overdose response that saves lives, but the drug does not address problematic drug use, addiction, or the underlying conditions that lead to overdoses. The opioid crisis is at its core a multidisciplinary, multisystem problem, and an effective response to the crisis requires collaboration across those various systems. This paper describes such a collaborative effort. The Tempe First-Responder Opioid Recovery Project is a multidisciplinary partnership that includes police officers, social workers, substance use peer counselors, public health professionals, police researchers, and drug policy/harm reduction researchers. The project, 10 months underway, trained and equipped Tempe (AZ) police officers to administer Narcan. In addition, a 24/7 in-person "Crisis Outreach Response Team" rapidly responds to any suspected overdose and offers follow-up support, referrals, and services to the individual (and loved ones) for up to 45 days after the overdose. We present preliminary project data including interviews with project managers, counselors, and police officers, descriptions of Narcan administrations in the field, and aggregate data on client service engagement. These data highlight the complexity of the opioid crisis, the collaborative nature of the Tempe project, and the importance of initiating a multidisciplinary, comprehensive response to effectively deal with the opioid problem.

Stiff isotropic lattices beyond the Maxwell criterion.

Materials with a stochastic microstructure, like foams, typically exhibit low mechanical stiffness, whereas lattices with a designed microarchitecture often show notably improved stiffness. These periodic architected materials have previously been designed by rule, using the Maxwell criterion to ensure that their deformation is dominated by the stretching of their struts. Classical designs following this rule tend to be anisotropic, with stiffness depending on the load orientation, but recently, isotropic designs have been reported by superimposing complementary anisotropic lattices. We have designed stiff isotropic lattices de novo with topology optimization, an approach based on continuum finite element analysis. Here, we present results of experiments on these lattices, fabricated by additive manufacturing, that validate predictions of their performance and demonstrate that they are as efficient as those designed by rule, despite appearing to violate the Maxwell criterion. These findings highlight the enhanced potential of topology optimization to design materials with unprecedented properties.
