The feasibility of workload monitoring among law enforcement officers: A multi-methodological approach

This study examined the feasibility of workload monitoring to assess internal workload in law enforcement officers (LEO) using a multi-methodological approach. Fifty front-line LEO completed workload surveys on workdays for eight weeks. Retention and adherence were assessed across the survey period. LEO completed usability and likelihood to continue questionnaires, while departmental administrators (n = 8) received workload reports and completed utility and sustainability questionnaires. A subsample of LEO and administrators participated in semi-structured interviews, following consensual qualitative research design. LEO retention (96%), survey adherence (94%), and usability scores (88.3/100) were high, with a moderate likelihood to continue to use the survey. Administration reported high utility and sustainability. The high adherence rates and usability scores, coupled with strong administrative support, suggest that workload monitoring may be a feasible strategy among LEO to monitor occupational workloads. The LEO and administration feedback highlight areas of improvement (e.g., data transparency, departmental collaboration) to inform future implementation.

Association between property investments and crime on commercial and residential streets: Implications for maximizing public safety benefits

Physical property investments enhance public safety in communities while alleviating the need for criminal justice system responses. Policy makers and local government officials must allocate scare resources for community and economic development activities. Understanding where physical property investments have the greatest crime reducing benefits can inform decision making to maximize economic, safety, and health outcomes. This study uses Spatial Durbin models with street segment and census tract by year fixed effects to examine the impact of physical property investments on changes in property and violent crime over an 11-year period (2008-2018) in six large U.S. cities. The units of analysis are commercial and residential street segments. Street segments are classified into low, medium, and high crime terciles defined by initial crime levels (2008-2010). Difference of coefficients tests identify significant differences in building permit effects across crime terciles. The findings reveal there is a significant negative relationship between physical property investments and changes in property and violent crime on commercial and residential street segments in all cities. Investments have the greatest public safety benefit where initial crime levels are the highest. The decrease in violent crime is larger on commercial street segments, while the decrease in property crime is larger on residential street segments. Targeting the highest crime street segments (i.e., 90th percentile) for property improvements will maximize public safety benefits.

Eu-doped ZIF-8 as a ratiometric fluorescence-scattering probe for the anthrax biomarker in food samples based on competitive coordination

Bacillus anthracis spores can cause contagious anthrax, so it is significant for the public safety to detect its biomarker dipicolinic acid (DPA). Ratiometric fluorescent probes for DPA have attracted great interest because of the self-calibration effect, but they suffer from the complicated construction of dual-emitting materials. With combining fluorescence and second-order scattering (SOS), Eu-doped Zn-based metal-organic framework (ZIF-8) was here designed as a ratiometric probe for DPA, avoiding the completed construction of dual-emitting materials. Eu-doped ZIF-8 exhibited no fluorescence but possessed strong SOS ascribed to the nanostructure. However, the competitive coordination of DPA not only triggered the antenna effect of Eu3+ but also caused the decomposition of Eu-doped ZIF-8. As a consequence, the fluorescence enhancement and the SOS weakness were observed upon the addition of DPA to Eu-doped ZIF-8. And thus, a ratiometric probe for DPA was constructed based on Eu-doped ZIF-8 by integrating fluorescence with SOS. The probe as-constructed could quantify DPA in a wide range of 0.1-150 μM with a rapid response (1 min) and a low detection limit (31 nM). It also displayed excellent manifestation for the analysis of food samples with reasonable accuracy (recoveries, 90.0%-101.5%) and satisfactory precision (RSDs, 0.6%-5.7%), offering a reliable tool for the supervision of the public safety.

NYC RxStat: Stakeholder perspectives on a national model public health and public safety partnership to reduce overdose deaths

NYC RxStat, the United States' first public health and public safety partnership aiming to reduce overdose deaths, began in 2012 and established a national model for cross-sector partnerships. The partnership aimed to integrate data-driven policing with actionable public health interventions and surveillance to develop and implement cross-sector overdose responses. With federal support, jurisdictions nationally have implemented public health and public safety partnerships modeled on RxStat. To inform partnership replication efforts, we conducted a stakeholder evaluation of RxStat. We conducted in-depth, semi-structured interviews with 25 current and former RxStat stakeholders. Interviews probed stakeholder perceptions of RxStat's successes, challenges, and opportunities for growth. Interview data were iteratively coded and thematically analyzed. Stakeholders reported certainty about the need for cross-sector collaboration and described cross-disciplinary tensions, challenges to collaboration and implementation, and opportunities for partnership optimization and growth. Findings informed 12 strategies to improve RxStat and partnerships in its model, organized into three opportunity areas: (1) ensure stakeholder and agency accountability; (2) build secure and mutually beneficial data systems; and (3) structure partnerships to facilitate equitable collaboration. Cross-sector partnerships offer a promising strategy to integrate the public health and safety sectors, but disciplinary tensions in approach may hamper implementation. Findings can inform efforts to implement and scale cross-sector partnerships.

A Review on Higher Education of Fire Safety in China

Along with the rapid urbanization and economic growth in China over the last four decades, the higher education in Fire Safety Science and Engineering has been developed and changed significantly. This work systemically reviews the origin and evolution of fire safety higher education history in China, from Fire Protection Technology (before the 1980s) to Fire Safety Science and Engineering (from about 1985 to the 2010s) and to Human-Oriented Public Safety and Smart Firefighting (from the 2010s to today). The scopes of fire safety discipline are discussed by introducing the requirements of firefighters, registered professional fire protection engineers and safety engineers in China. The courses and curriculum in fire safety higher education in representative universities are introduced and compared in detail. By comparing their undergraduate and postgraduate programmes, we explain the context of fire safety education in different universities. From a historical viewpoint, we introduce the unique features and the diversity developed in different institutes, based on the evolution of programme documents and first-hand teaching materials. This review aims to introduce the higher education systems of fire safety in China to the world and encourage more international collaboration with the Chinese fire safety science and engineering communities in the future.

Using formative evaluation of a community-based opioid overdose prevention program to inform strategic communication for adoption, implementation, and sustainability

BACKGROUND

Opioid addiction and overdose is a public health problem in the United States and is expected to remain with substance use increasing due to the COVID-19 pandemic. Communities that approach this issue through multi-sector partnerships experience more positive health outcomes. Understanding motivation for stakeholder engagement in these efforts is essential to successful adoption, implementation, and sustainability particularly in the shifting landscape of needs and resources.

METHODS

A formative evaluation was conducted on the C.L.E.A.R. Program in Massachusetts, a state heavily impacted by the opioid epidemic. A stakeholder power analysis identified appropriate stakeholders for the study (n = 9). The Consolidated Framework for Implementation Research (CFIR) guided data collection and analysis. Surveys (n = 8) examined perception and attitudes on the program; motivations and communication for engagement; and, benefits and barriers to collaboration. Stakeholder interviews (n = 6) explored the quantitative findings in more detail. Surveys were analyzed using descriptive statistics and a content analysis with deductive approach was conducted for stakeholder interviews. The Diffusion of Innovation (DOI) Theory guided recommendations for communications to engage stakeholders.

RESULTS

Agencies represented a range of sectors and the majority (n = 5) were familiar with the C.L.E.A.R.

PROGRAM

Despite the many strengths of the program and existing collaboration, based on the coding densities of each CFIR construct stakeholders identified crucial gaps in the services the program provided and noted that the overall infrastructure of the program could be enhanced. Opportunities for strategic communication to address the stages of DOI align with the gaps identified in the CFIR domains to result in increased agency collaboration and expansion of services into the surrounding communities to ensure sustainability of the C.L.E.A.R.

PROGRAM

CONCLUSIONS

This study explored factors necessary for ongoing multi-sector collaboration and sustainability of an existing community-based program especially given the changing context from COVID-19. Findings informed both program revisions and communication strategies to promote the program to new and existing collaborating agencies and the community served, and identify effective communication approaches across sectors. This is essential for successful implementation and sustainability of the program, especially as it is adapted and expanded to address post-pandemic times.

TRIAL REGISTRATION

This study does not report results of a health care intervention on human participants, however it was reviewed and determined an exempt study with the Boston University Institutional Review Board (IRB #H-42107).

A Cluster of Health Symptoms After a Law Enforcement Operation: A Case Study

Law enforcement officers (LEOs) often encounter rapidly changing and uncontrolled situations that expose them to various hazards. A law enforcement agency requested an evaluation by the National Institute for Occupational Safety and Health (NIOSH) when multiple LEOs reported illness after executing a search warrant and taking a suspect into custody. NIOSH investigators interviewed LEOs and reviewed medical records, forensic laboratory results for collected evidence, and environmental testing results of samples taken after the operation. Two-thirds (25 of 38) of LEOs who participated in the operation reported ≥1 symptom. Eleven LEOs met a case definition for influenza-like illness (ILI). Members of one unit were more likely to have ILI than non-members (prevalence ratio (PR), 4.1; 95% confidence interval (CI): 1.3-13.0; p = 0.01). Influenza vaccination was associated with a lower prevalence of ILI (PR, 0.2; 95% CI, 0.1-0.9; p = 0.02). Preventing employees from working while ill and annual influenza vaccination might prevent similar occurrences.

Reimagining public safety: Public opinion on police reform and gun violence prevention by race and gun ownership in the United States

Inequitable experiences of community gun violence and victimization by police use of force led to nationwide calls to "reimagine public safety" in 2020. In January 2021, we examined public support among U.S. adults for 7 policy approaches to reforming policing and investing in community gun violence prevention. Using a nationally representative sample (N = 2778), with oversampling for Black Americans, Hispanic Americans, and gun owners, we assessed support overall and by racial, ethnic, and gun owner subgroups. Overall, we found majority support for funding and implementing police and mental health co-responder models (66% and 76%, respectively), diversion from incarceration for people with symptoms of mental illness (72%), stronger laws to assure police accountability (72%), and funding for community-based and hospital-based gun violence prevention programs (69% and 60%, respectively). Support for redirecting funding from the police to social services was more variable (44% overall; White: 35%, Black: 60%, Hispanic: 43%). For all survey items, support was strongest among Black Americans. Gun owners overall reported lower support for public safety reforms and investments than respondents who did not own guns, but this distinction was found to be driven by White gun owners. The views of Black gun owners were indistinguishable from Black non-owners and were similar to White non-owners on most issues. These findings suggest that broad public support exists for innovative violence reduction strategies and public safety reforms.

Building towards community-oriented policing: Forming an academic medical center partnership with local police

In the Spring of 2020, protective services for the Milwaukee Regional Medical Center (MRMC) Campus began a year-long transition process from the Milwaukee County Sheriff's Department to the Wauwatosa Police Department (WPD). This transition occurred during a time of focused local and national discourse regarding policing in diverse community settings. In response, the MRMC leadership formed the Ad Hoc Advisory Committee for the Transition of Protective Services (AATOPS). Over the course of six months, AATOPS members conducted site visits, developed a training manual, and divided into subcommittees to establish recommendations and key performance indicators in four primary areas: 1) Diversity and Inclusion of the WPD; 2) Psychological Evaluation of WPD Officers; 3) Use and De-Escalation of Force within the WPD; and 4) Communicating the Imminent Transition of Protective Services to MRMC organization employees, faculty, students, trainees, and patients. In this paper, we detail the process of organizing an accountable and collaborative approach to police and medical and academic campus relationships. At the end of the transition period, both the WPD and MRMC expressed commitment to a continued partnership to ensure the safety and security of all on the MRMC campus.

An optimization model to assign seats in long distance trains to minimize SARS-CoV-2 diffusion

The unprecedented spread of SARS-CoV-2 has pushed governmental bodies to undertake stringent actions like travel regulations, localized curfews, curb activity participation, etc. These restrictions assisted in controlling the proliferation of the virus; however, they severely affected major economies. This compels policymakers and planners to devise strategies that restrain virus spread as well as operationalize economic activities. In this context, we discuss some of the potential implications of seat inventory management in long-distance passenger trains and create a balance between operators' operational efficiency and passengers' safety. The paper introduces a novel seat assignment policy that aims to mitigate virus diffusion risk among passengers by reducing interaction among them. A mixed-integer linear programming problem has been formulated that concomitantly maximizes the operator's revenue and minimizes virus diffusion. The validity of the model has been tested using real-life data obtained from Indian Railways. The computational results show that a mere 50% capacity utilization may distress operators' economics and prove ineffectual in controlling SARS-CoV-2 transmission. The proposed model produces encouraging results in restricting virus diffusion and improving revenue even under 100% capacity utilization.

Pathway mapping as a tool to address police use of force in behavioral health crisis

Police use of force is a significant problem in many communities, particularly related to episodes of behavioral health crisis where police are called to respond. Fragmentation of the behavioral health care system creates a revolving door where many residents with behavioral health challenges cycle in and out of the system, often accessing services via the 9-1-1 emergency system during a crisis episode. This work leverages ethnographic and participatory techniques to build a pathway map in order to represent and characterize the behavioral health crisis system in metropolitan Phoenix, Arizona, United States. Map findings illustrate that many nominally existing connections are functionally distant when viewed through the lens of a clinical handoff. The resulting pathway map can be used as a planning and confirmatory tool for community members, practitioners, and policymakers to address challenges in behavioral health and public safety.

A review of workplace mental health interventions and their implementation in public safety organizations

OBJECTIVE

Workplace mental health is relevant to public safety organizations due to the exposure that many public safety personnel (PSP) have to psychological trauma in the course of their daily work. While the importance of attending to PSP mental health has been established, the implementation of workplace mental health interventions is not as well understood. This scoping review describes workplace mental health interventions and their implementation in public safety organizations.

METHODS

English published primary studies with any publication date up to July 3, 2020 were considered. JBI methodology and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews was followed.

RESULTS

89 citations met inclusion criteria out of the 62,299 found. Articles and reports found were largely published within the last decade, most frequently from Western nations, and most often applied to police, followed by firefighters. The focus of interventions was commonly stress management and resilience, and a frequent implementation strategy was multi-session group training. Comprehensive quality improvement initiatives, a focus on supervisors and managers, and interventions across primary, secondary, and tertiary prevention, were infrequent.

CONCLUSION

Public safety organizations are frequently reporting on stress management and resilience interventions for police and firefighters, implemented through multi-session group training. A focus across a range of PSP, including paramedics, corrections officers, and emergency dispatchers, using implementation strategies beyond group training, is suggested. This area of research is currently expanding, with many studies published within the past decade; ongoing evaluation of the quality of interventions and implementation strategies is recommended.

Experiences of families of public safety personnel: a systematic review protocol of qualitative evidence

BACKGROUND

Public safety occupations are well-recognized to be dangerous and stressful. Despite recent attention on post-traumatic stress injuries among public safety personnel, there has been considerably less attention paid to the ongoing ways in which the risks and requirements associated with those occupations shape family life, and how families respond and adapt to those lifestyle dimensions. This systematic review aims to understand how day-to-day family life is affected and shaped when a family member works in a public safety sector, such as fire, police, paramedic, corrections, and emergency communications.

METHODS

Qualitative studies that examine the experiences of families or family members of public safety personnel will be included in this review, with no date or language restrictions. An initial search of Embase and CINAHL will be conducted, followed by an analysis of text words contained in the title and abstract, and of the index terms used to describe the articles. Databases to be searched for published studies include MEDLINE, Embase, Web of Sciences, CINAHL, PsycINFO, and Sociological Abstracts. Titles and abstracts will be screened by two independent reviewers. The full texts of selected studies will be assessed in detail, and findings and their illustrations will be extracted and aggregated. Any disagreements between the reviewers that arise at each stage will be resolved through discussion, or by a third reviewer. Further analysis of the synthesized findings will be informed by family systems theory.

DISCUSSION

The ways that occupational risks and requirements shape family life have been better investigated within other high-risk occupation groups, which has led to productive advancements in organizational policies and supports in the respective sectors. An understanding of the experiences which typify family life ongoing within PSP sectors is a critical gap in the development of meaningful family-informed occupational initiatives and supports.

Maturity Levels of Public Safety Applications using Unmanned Aerial Systems: a Review

Unmanned Aerial Systems (UAS) are becoming increasingly popular in the public safety sector. While some applications have so far only been envisioned, others are regularly performed in real-life scenarios. Many more fall in between and are actively investigated by research and commercial communities alike. This study reviews the maturity levels, or “market-readiness”, of public safety applications for UAS. As individual assessments of all applications suggested in the literature are infeasible due to their sheer number, we propose a novel set of application categories: Remote Sensing, Mapping, Monitoring, Human-drone Interaction, Flying Ad-hoc Networks, Transportation, and Counter UAV Systems. Each category’s maturity is assessed through a literature review of contained applications, using the metric of Application Readiness Levels (ARLs). Relevant aspects such as the environmental complexity and available mission time of addressed scenarios are taken into account. Following the analysis, we infer that improvements in autonomy and software reliability are the most promising research areas for increasing the usefulness and acceptance of UAS in the public safety domain.

Work-Family Conflict, Depression, and Burnout Among Jail Correctional Officers: A 1-Year Prospective Study

BACKGROUND

Correctional officers (COs) experience elevated rates of mental and physical ill-health as compared with other general industry and public safety occupations. The purpose of this study was to investigate demographic, mental health, job tenure, and work-family characteristics and their prospective association to burnout within and between jail officers during one year of new employment.

METHODS

In 2016, newly hired jail officers (N = 144) completed self-reported surveys across four time points in a one-year prospective study at a Midwestern United States urban jail. Linear mixed-effects and growth modeling examined how work-family conflict (W-FC) and depressive symptoms relate to perceptions of burnout over time.

RESULTS

Jail officer burnout increased and was related to rises in W-FC and depression symptoms. Within-person variance for W-FC (B pooled  = .52, p < .001) and depression symptoms (B pooled  = .06, p < .01) were significant predictors of burnout. Less time on the job remained a significant predictor of burnout across all analyses (B pooled  = .03, p < .001).

CONCLUSIONS

Results from this study indicate that burnout increased during the first year of new employment; and increased W-FC, higher depression, and brief tenure were associated with burnout among jail COs. Future study of correctional workplace health is needed to identify tailored, multilevel interventions that address burnout and W-FC prevention and early intervention among COs.

Does the evidence support brief (≤30-mins), moderate (31-60-mins), or long duration naps (61+ mins) on the night shift? A systematic review

We performed a systematic review of four databases to determine if the evidence supports a short or long duration nap during night shifts to mitigate fatigue, and/or improve health, safety, or performance for emergency services and public safety personnel (PROSPERO CRD42020156780). We focused on experimental research and evaluated the quality of evidence with the grading of recommendations, assessment, development, and evaluation (GRADE) framework. We used the Cochrane Collaboration's risk of bias tool to assess bias and reported findings using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. Our search yielded n = 10,345 records and n = 44 were reviewed in full-text. Inter-rater agreement during screening was substantial (Kappa = 0.66). We retained n = 11 publications, reporting on n = 7 experimental studies with a cumulative sample size of n = 140. We identified wide variation in study design, napping interventions (i.e., timing, placement, and duration), and outcomes. We identified mixed findings comparing brief, moderate, and long duration naps on outcomes of interest. All seven studies presented serious risk of bias and the quality of evidence was rated as low. Based on the best available evidence, decisions regarding nap duration during night shift work should be based on time (post-nap) and outcome.

Proactive psychological programs designed to mitigate posttraumatic stress injuries among at-risk workers: a systematic review and meta-analysis

BACKGROUND

Public safety personnel and frontline healthcare professionals are at increased risk of exposure to potentially psychologically traumatic events (PPTE) and developing posttraumatic stress injuries (PTSI, e.g., depression, anxiety) by the nature of their work. PTSI are also linked to increased absenteeism, suicidality, and performance decrements, which compromise occupational and public health and safety in trauma-exposed workers. Evidence is lacking regarding the effectiveness of "prevention" programs designed to mitigate PTSI proactively. The purpose of this review is to measure the effectiveness of proactive PTSI mitigation programs among occupational groups exposed to PPTE on measures of PTSI symptoms, absenteeism, and psychological wellness.

METHODS

Five electronic databases were searched per PRISMA guidelines for English or French peer-reviewed studies from 2008 to 2019 evaluating PTSI and psychological wellness in adults exposed to occupational PPTE. The risk of bias was assessed using the Newcastle-Ottawa Scale.

RESULTS

We identified 42 studies evaluating 3182 public safety and frontline healthcare professionals, PPTE-exposed educational staff, and miners. Significant overlap was found across program themes that included mindfulness, psychoeducation, resilience promotion, and stress management strategies. Post-program effect sizes were small (SMD < 0.5) to moderate (SMD < 0.8) for reductions in PTSI symptoms and for promoting measures of well-being as indicated by a meta-analysis on 36 studies. There was no evidence for significant reductions in substance use, absenteeism, or biomarkers of distress except for heart rate. Subgroup analyses indicated that multimodal programs effectively improved general psychological health, while resilience programs improved measures of depression, burnout, coping, and resilience. Effect sizes for resilience, depression, and general psychological health improvements were greatest immediately or 1-month post-training, while improvements in PTSD symptoms and coping were larger at longer follow-up. Studies were of moderate quality and risk of bias.

CONCLUSIONS

The current results showcase modest evidence for time-limited reductions in PTSI following participation in holistic programs that promote resilience, stress, and emotion regulation among at-risk workers. Implications for organizational implementation of proactive PTSI mitigation programs and areas of future research are discussed.

The burden of cycling-related trauma to the orthopaedic and trauma department of a level 1 trauma hospital in Adelaide, South Australia

Background

With the fourth largest metropolitan population density, motor vehicle drivers in Adelaide, South Australia, record the most number of motor vehicle insurance claims in Australia. Previous studies have shown a rise in cycling-related emergency department presentations from 2005 to 2010. There is no specific data available specifically related to South Australia. Our institution is the largest level 1 trauma centre in South Australia and Northern Territory and has a local geographic pool of the central metropolitan region of Adelaide.

The aims of this study were to establish the demographics of cycling-related presentations to our institution that involved the admission of a patient under the Orthopaedic and Trauma service. Secondary aims were to investigate whether there were any common variables among these presentations that could be modified to prevent or reduce the morbidity of cycling-related trauma.

Methods

A prospective study was performed at our institution from 1 March 2018 until 31 December 2019 of all inpatient admissions under the Orthopaedics and Trauma department, where the patient was injured as a cyclist. We collated patient-reported information about the accident and their cycling habits.

Results

One hundred and ten patients were included in the study. One hundred and thirty-one injuries were recorded, requiring 89 surgical procedures. Eighty were upper limb injuries (61%), 49 were lower limb (37%), and 2 injuries occurred in either the spine or ribs. The most common reason for the accident was excessive cyclist speed.

Conclusions

The majority of cyclists admitted to our unit with orthopaedic injuries were male patients who assessed themselves as experienced riders, and yet still were involved in accidents that resulted predominantly from episodes of poor judgement. Speed is a common and avoidable factor involved in the presentation of orthopaedic-related trauma to the public system. Involvement of other vehicles was relatively uncommon, as was poor weather; upper limb injuries predominate in this group.

Legal scenarios in the coronavirus time: Medico legal implications in the aspects of governance

Along with rising levels of the infection around the world, the state of emergency prompted by the COVID-19 pandemic has also been having a heavy legal impact. The situation is posing important criminal challenges, as well as an ocean of social and public health issues around the world. It has not only directly affected constitutionally-guaranteed rights and individual freedoms, but also brought to the fore certain types of criminal offence that had previously been of little practical importance, such as the crime of 'maliciously or unintentionally causing an epidemic'. Different countries and states have introduced policies to manage the emergency at different times and in different ways. The measures adopted have been the object of much criticism, also raising questions of constitutional legitimacy in countries like Italy. The present contribution begins with a brief outline of the different international scenarios. Then we examine some of the medicolegal aspects of criminal offences previously envisaged and newly introduced since the arrival of the pandemic. We suggest the need for a sort of 'code of public health laws for the time of coronavirus', that could also be applied to other public health emergencies, pandemic or otherwise. The idea is to give operators in the sector and the general population the opportunity to identify clear and simple rules to follow in the current complex global situation. We need a new, appropriate interpretation of the 'boundaries' of our individual rights in relation to the need to safeguard the wider community and its more vulnerable members.

Pandémie et communautés minoritaires marginalisées : vers une approche inclusive en santé publique?

The pandemic has highlighted the complexity of public health measures and their side effects, the intricacy of the underlying health, social and political phenomena at play as well as their specificity for marginalized minority communities. Based on this experience, this commentary suggests that it would be relevant in the future to develop consultation mechanisms that take into account the entire population, including marginalized minority groups, in order to better inform decision-making processes in times of pandemic. In a context of fluid crisis, any consultation process must take into account the limits of what is possible and mourn the comprehensiveness in favour of repeated iterations of dialogue, mediation and decision-making. This means creating conditions favourable to the consideration of the most vulnerable people and groups' voices by public authorities. In order to prepare for the next crises, it is necessary to develop strong links between public institutions and communities, both of majorities and minorities, in order to define the mechanisms favouring the emergence of truly inclusive public health, taking into account the physical, mental and social health of the population.

The influence of firearms trafficking on gunshot injuries in a co-offending network

Individuals at the greatest risk of gunshot victimization are often prohibited from legally acquiring guns in the U.S. due to prior felony convictions or other disqualifications. Prohibited persons often rely on others - such as friends, family members, fellow gang members, and gun brokers - to acquire firearms. This study examines whether the sources of guns recovered from high-risk individuals differ relative to the sources of guns recovered more generally in a major U.S. city, and whether illegally-diverted guns are associated with increased gunshot victimization risk. Using official data, we recreate the co-offending network of individuals in Boston who were arrested or contacted by the police with at least one other person between 2007 and 2014. Firearms trace data are then used to develop measures of the shortest distance between individuals and firearms in their immediate network. Results suggest guns with markers of illegal diversion are more likely to be recovered in the highest risk sector of the network and that the probability of gunshot victimization increases with decreased distance to an individual linked to firearms with markers of illegal trafficking.

Chiropractic students call for action against unsubstantiated claims

Background

The 2019 coronavirus pandemic is a current global health crisis. Many chiropractic institutions, associations, and researchers have stepped up at a time of need. However, a subset of the chiropractic profession has claimed that spinal manipulative therapy (SMT) is clinically effective in improving one’s immunity, despite the lack of supporting scientific evidence. These unsubstantiated claims contradict official public health policy reflecting poorly on the profession. The aim of this commentary is to provide our perspective on the claims regarding SMT and clinically relevant immunity enhancement, drawing attention to the damaging ramifications these claims might have on our profession’s reputation.

Main text

The World Federation of Chiropractic released a rapid review demonstrating the lack of clinically relevant evidence regarding SMT and immunity enhancement. The current claims contradicting this review carry significant potential risk to patients. Furthermore, as a result of these misleading claims, significant media attention and public critiques of the profession are being made. We believe inaction by regulatory bodies will lead to confusion among the public and other healthcare providers, unfortunately damaging the profession’s reputation. The resulting effect on the reputation of the profession is greatly concerning to us, as students.

Conclusion

It is our hope that all regulatory bodies will protect the public by taking appropriate action against chiropractors making unfounded claims contradicting public health policy. We believe it is the responsibility of all stakeholders in the chiropractic profession to ensure this is carried out and the standard of care is raised. We call on current chiropractors to ensure a viable profession exists moving forward.

Private and public willingness to pay for safety: A validity test

Stated preference (SP) methods are often used to elicit an affected population's preferences for, e.g., increased safety or better environmental quality. SP methods are based on hypothetical market scenarios which have advantages, since decision alternatives are known to the analysis, but also necessitate thorough validity tests of the results, since decisions are hypothetical. This study suggests a validity test based on theoretical predictions and empirical findings for private and public safety measures. According to the test, willingness to pay (WTP) for a public safety measure should exceed or be equal to the private one. Based on a rich data set eliciting both private and public WTP the results show that private WTP exceeds public WTP. Hence, the findings in this study highlight the importance of validity tests of preference estimates for safety, and suggest that WTP also for a private safety measure should be elicited in studies eliciting WTP for public safety measures, to allow for the validity test.

Alcohol and the Law

In the intersection of alcohol ingestion with the law, medical ethics, and public safety, physicians are often unsure about how to proceed. Physicians' primary focus should be on patient education with an ethical and legal duty to warn the patient of the adverse effects of alcohol. Warning third parties of potential harm related to alcohol-related impairment may involve a breach of patient confidentiality; therefore it should only be undertaken after careful analysis suggests that the risk for significant harm exceeds the burden that results to the patient from warning others. The law remains vague in this area.

Are electric scooters promoted on social media with safety in mind? A case study on Bird's Instagram

Electric scooter (e-scooter) companies are growing in popularity across the United States looking to take advantage of the rideshare economy by providing an independent alternative to cars and bicycles. While e-scooter transportation could reduce emissions, and automobile congestion in local areas, powered two-wheeler drivers are extremely vulnerable to road risks. News reports of e-scooter crashes and fatalities have started to accumulate. Earlier research has demonstrated that the ways in which companies promote and demonstrate use of their product or service through social media influences consumer behavior. In the U.S. in 2018, this study examined the official Instagram account of Bird, the e-scooter market share leader with over 66,000 followers, to determine how much it emphasized safety in its posts. All posts to Bird's official Instagram account were collected from 22 September 2017 to 9 November 2018 (n = 324) and rules for coding content were developed. Among all posts, 69.14% contained a person visible with a Bird e-scooter, 6.17% contained persons wearing protective gear, 6.79% had protective gear somewhere in the post, and 1.54% of posts mentioned protective gear in the comment box. About 69.44% of the posts were reposts, and among reposts, 7.11% had persons wearing protective gear. Posts to Bird's official Instagram rarely showed e-scooters being used with protective gear. Photos of customers' experiences with Bird, via reposts, rarely featured protective gear potentially normalizing these behaviors among customers. Public health practitioners may need to establish interventions to promote use of protective gear while operating escooters.

The geography of crime and violence surrounding tobacco shops, medical marijuana dispensaries, and off-sale alcohol outlets in a large, urban low-income community of color

Tobacco shops, medical marijuana dispensaries (MMD), and off-sale alcohol outlets are legal and prevalent in South Los Angeles, California-a high-crime, low-income urban community of color. This research is the first to explore the geographic associations between these three legal drug outlets with surrounding crime and violence in a large low-income urban community of color. First, spatial buffer analyses were performed using point-location and publically accessible January-December 2014 crime data to examine the geography of all felony property and violent crimes occurring within 100, 200, 500, and 1000-foot buffers of these three legal drug outlet types across South Los Angeles. Next, spatial regression analyses explored the geographic associations between density of these outlets and property and violent crimes at the census tract level. Results indicated that mean property and violent crime rates within 100-foot buffers of tobacco shops and alcohol outlets-but not MMDs-substantially exceeded community-wide mean crime rates and rates around grocery/convenience stores (i.e., comparison properties licensed to sell both alcohol and tobacco). Spatial regression analyses confirmed that tobacco shops significantly positively associated with property and violent crimes after controlling for key neighborhood factors (poverty, renters, resident mobility, ethnic/racial heterogeneity). Thus, study findings provide the first empirical evidence that tobacco shops may constitute public health threats that associate with crime and violence in U.S. low-income urban communities of color. Implementing and enforcing control policies that regulate and monitor tobacco shops in these communities may promote community health by improving public safety.

Work-related stress as a cardiovascular risk factor in police officers: a systematic review of evidence

PURPOSE

Several studies suggest that work-related stress in police officers may be associated with an increased risk of cardiovascular diseases. A systematic review of studies is, however, still lacking.

METHOD

According to PRISMA statement, a systematic search of PubMed, ISI Web of Science, Cinahl and PsychInfo electronic databases was undertaken. Studies published in English between 1/1/2000 and 31/12/2016 were included. A studies quality assessment was performed using the Newcastle Ottawa scale (NOS).

RESULTS

The preliminary search retrieved 752 records. After selection, 16 studies (total population 17,698) were retrieved. The average quality of studies was low. Exposure to stress in cross-sectional studies was inconstantly associated with hypertension, obesity, dyslipidaemia, and impaired glucose metabolism. In addition, there was a prevalence of positive studies showing an association between stress and cardiovascular disease morbidity. Studies of higher quality, such as longitudinal studies on large sample size, were more supportive of a significant positive association between stress and cardiovascular risk factors. Results were, however, often conflicting and inconsistent with regard to definitions and measurement of stress, features of individual study design, study conduct, and conclusions drawn.

CONCLUSIONS

A sound precautionary principle would be to adopt worksite health promotion programs designed to implement stress management strategies in this category of workers.

How Agricultural Media Cover Safety Compared with Periodicals in Two Other Hazardous Industries

This analysis featured a uniquely broad look at challenges and potentials for engaging agricultural and other industrial media more effectively in covering safety. It involved a content analysis of selected industry periodicals serving agriculture, mining, and transportation, which are three of the nation's most hazardous industries, in terms of human safety. Use of the social amplification of risk framework (SARF) provided insight on safety coverage. In particular, it tested previous research indicating that media coverage tends to amplify (increase) more than attenuate (decrease) a sense of risk. Analysis involved 18 periodicals (9 agriculture, 7 transportation, and 2 mining) spanning a five-year period from 2008 to 2012. Full-text digital analysis identified terms found in safety articles across all three industries. A manual review of articles revealed the quantity and nature of safety coverage within and among these industries. Results identified 528 safety-related articles published during the period. Transportation and mining periodicals averaged more than twice as many safety articles as the agricultural periodicals. The amount of coverage within the three industries also varied greatly. Findings on the nature of coverage supported previous media research within the SARF. Coverage across all three industries was clearly oriented more to amplifying than to attenuating risk. This study adds to the understanding of variations, commonalities, challenges, and potentials for enhancing safety coverage by media serving these three industries. It also provides direction for engaging industry media more effectively in the public safety mission. The authors recommend seven areas of opportunity for further research.

The Separation Wall and the right to healthcare

Nowadays, the concepts of soldier and war have changed due to terrorism and the war on terrorism. According to the literature, to prevent terrorism, it is possible to use more violence, but how can we grant the safety of many versus the dignity of a few? In Israel, in order to protect civilians against possible terrorist attacks, Palestinian ambulances that would reach the Israeli hospitals (or the Palestinian hospitals in East Jerusalem) must be quickly controlled. However, many times, at the checkpoint, patients have to wait for an Israeli vehicle that will take them to Israel. This procedure causes many delays in medical emergency. How to avoid that terrorists may receive better care than Palestinian civilians may just because they are already on the Israeli side of the Separation Wall? How is it possible to ensure the life and safety of many, without denying the right to healthcare to somebody? How to decide when the State requirements conflict with traditional medical duties? Is it acceptable to provide health care to a terrorist? What should be done when it is uncertain whether the ambulance transports weapons besides patients? These questions call upon the core role of the doctor and of the medical profession: taking care of all sick persons. The care is the starting point of ethics. If we do not care about other human beings we do not have a real moral comprehension of any human ideal or action. For this reason we can say that the care is the premise of morality. The rights of all citizens, including the claim to public security, grounds on the care for each individual who needs help.

Mental health outreach and street policing in the downtown of a large French city

CONTEXT

Marseille, the second largest city in France, has a large population of homeless persons. A mental health outreach team was created in 2005 as a response to high rates of mental illness among this group. In a national political context where security is a government priority, a new central police station was created in Marseille in 2006 to address robberies, violence and illegal traffic in the downtown area of the city. While not directly related to such crimes, police also are responsible for public safety or behavioral issues related to the presence of individuals who are homeless in this area.

OBJECTIVE

This report on a two-year pilot study (2009-2011) addresses collaborative work between a mental health outreach team and the police department responding to the clinical needs of persons who are homeless with serious psychiatric disorders. It also describes the homeless persons' interactions with, and perceptions of the presence of, police and mental health professionals on the streets.

METHODS

Investigators adopted a mixed-methods approach. Data were collected on 40 interactions using brief standardized report for each interaction. Focus groups were conducted with police officers, outreach team members, peer workers, and service users. Minutes of partnership meetings between police officers and outreach workers also served as a source of qualitative data.

RESULTS

Outreach workers initiated just over half (n=21) of the encounters (n=40) between police and outreach workers. Interactions mainly involved persons with psychosis (77%), the vast majority (80%) of which involved persons in an acute phase of psychosis. Two key themes that emerged from data analysis included the violent nature of life on the streets and the high percentage of ethnic minorities among subjects of the interactions. In addition, it was found that the practices of the outreach workers are sometimes similar to those of the police, especially when outreach workers use coercive methods. "Users" (homeless persons) described police as sometimes using less coercion than the outreach team, and noted that they were more fearful of psychiatrists than police.

CONCLUSION

Formal initiatives between mental health outreach teams and police departments involve some common street practices. This study demonstrates the potential for closer working relationships between the two parties to help persons who are homeless with mental illnesses receive needed care, and to reduce inappropriate coercion including involuntary hospitalization and arrests.
