Factors Associated with Lost Time Injury among Paramedics in Victoria, Australia.

BACKGROUND: The dynamic and uncontrolled nature of paramedic work frequently exposes these workers to physical and psychological injury. Often paramedic injury rates are estimated based on national injury surveillance data or compensation databases. These data sources tend to only capture cases of a more serious nature and overlook the broader factors that contribute to injury. This limits our understanding of the true burden of paramedic injury and the characteristics associated with increased injury severity. OBJECTIVES: To describe the incidence and proportions of paramedic occupational injury in Victoria, Australia, and to determine the injury-related characteristics associated with lost time from work. METHODS: A retrospective analysis of paramedic injury report data from the single state-wide ambulance service in Victoria, Australia - Ambulance Victoria. Injuries reported between 1 January 2015 and 30 June 2020 were included. Chi-square tests of independence were used to explore shift and injury characteristic variables that may be associated with time lost from work. RESULTS: Over the study period, 7,591 paramedic injuries were reported that met the inclusion criteria, of which 2,124 (28%) resulted in lost time from work. The cumulative incidence of paramedic injury was 333.8 injuries per 1,000 FTE workers per year, and the rate of lost time injury was 93.0 per 1,000 FTE workers per year. Musculoskeletal injuries were the most frequently reported injury type irrespective of lost time status. Manual handling followed by psychological stressors were the two leading mechanisms of injury based on incidence. Psychological injury was associated with lost time from work (X2= 384.2, p < 0.001). Conversely, injury to the head and neck (X2= 7.5, p = 0.006), and upper limb injuries (X2= 104.5, p < 0.001), were more strongly associated with no lost time from work. CONCLUSIONS: Paramedics working in Victoria have a higher rate of work-related injury than other Australian workers. Injury-related factors that are often overlooked, such as time, shift type, location, and injury characteristics, all contribute to an increased risk of lost time injury. An understanding of the factors that contribute to an increase in injury severity may facilitate the development and targeting of appropriate interventions.

Exploring factors associated with paramedic work-related psychological injury through data linkage.

INTRODUCTION: In comparison to the general population and other emergency services workers, paramedics experience high rates of work-related psychological injury. However, there is limited understanding of the case and practitioner-related factors that increase the risk of psychological injury among these workers. This paper aims to identify case and practitioner-related factors associated with paramedic work-related psychological injury in Victoria, Australia, through data linkage. METHODS: Data linkage of 7,223 paramedic injury reports with electronic patient care records, and paramedic demographic data from the single state-wide ambulance service in Victoria, Australia - Ambulance Victoria. Injuries reported between 1 January 2015 and 30 June 2020 were included. Factors associated with paramedic psychological injury were assessed using multivariable logistic regression analysis. RESULTS: A total of 4,641 (64%) injury reports were successfully linked, of which, 244 (5%) were psychological injuries. Shift hours between 0401 and 0800 (AOR 1.83; 95%CI: 1.12-2.97), cardiac arrest or deceased patient attendances (AOR 2.15; 95%CI: 1.06-4.34), hospital or medical center case locations (AOR 2.44; 95%CI: 1.22-4.91), and Priority 0 (AOR 2.27; 95%CI: 1.26-4.09), Priority 2 (AOR 1.56; 95%CI: 1.04-2.33), and Priority 3 (AOR 1.95; 95%CI: 1.15-3.32) dispatch codes were associated with increased odds of psychological injury. Increasing patient age (AOR 0.98; 95%CI: 0.97-0.99), and the absence of other emergency services on scene (AOR 0.50; 95%CI: 0.34-0.72) were associated with decreased odds of paramedic psychological injury. CONCLUSIONS: This is the first study to collectively examine and identify EMS case and practitioner-related characteristics associated with paramedic psychological injury through data linkage of EMS agency-level data sources. PRACTICAL APPLICATION: The findings of this study highlight the dispatch case characteristics that may increase the risk of a paramedic sustaining a work-related psychological injury, and consequently facilitate the early identification, intervention, and support of the individuals most at risk.

Occupational injury among paramedics: a systematic review.

INTRODUCTION: Paramedics are frequently exposed to acute and/or chronic environmental, operational and patient-related factors that increase their risk of physical and psychological injury. However, there has been wide variation in reported paramedic injury rates. This systematic review aims to synthesise the evidence to examine the incidence and nature of occupational injury among paramedics. METHODS: This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO 2020: CRD42020164556). A systematic search of four electronic databases was conducted for the years 2004-2019. Peer-reviewed studies examining the incidence and proportions of paramedic occupational injury within civilian emergency medical services (EMS) were included. Injury types, mechanisms, contributing factors and incidence of injury were synthesised narratively. RESULTS: Twelve studies met the inclusion criteria. The incidence of injury ranged from 29.7 to 345.6 injuries per 1000 workers per year. Sprains and strains were the most reported injury types, and the trunk and upper limbs were the main sites. Body motion was the most frequently reported mechanism of injury, accounting for 35%-55% of all injuries. Female paramedics had a proportionally higher rate of injury compared with male paramedics. Paramedics aged 25-34 years accounted for the majority of fatal (mean 34.0%) and non-fatal (mean 51.7%) injuries. CONCLUSION: This review highlights the increased risk of occupational injury among paramedics and provides further insight into their overall injury profile.

Factors associated with return to work among survivors of out-of-hospital cardiac arrest.

BACKGROUND: Although out-of-hospital cardiac arrest (OHCA) is a major cause of global mortality, survival rates have increased over the last decade. As such, there is an increasing need to explore long-term functional outcomes of survivors, such as return to work (RTW). METHODOLOGY: We analysed baseline and 12-month follow-up data from the Victorian Ambulance Cardiac Arrest Registry for patients that arrested between 2010 and 2016 who were working prior to their arrest. We also conducted more detailed RTW interviews in a subset of OHCA survivors who arrested between July and September 2017. Factors associated with RTW were assessed using multivariable logistic regression analysis. RESULTS: A total of 884 previously working survivors were included in the analysis, 650 (73%) of whom RTW. Male sex (AOR 1.80; 95%CI: 1.10-2.94), arrests witnessed by emergency medical services (AOR 2.72; 95%CI: 1.50-9.25), discharge directly home from hospital (AOR 4.13; 95%CI: 2.38-7.18) and favourable 12-month health-related quality of life according to the EQ-5D were associated with RTW. Increasing age (AOR 0.97; 95%CI: 0.95-0.98), traumatic arrest aetiology (AOR 0.18; 95%CI: 0.04-0.77), and labour-intensive occupations (AOR 0.44; 95%CI: 0.29-0.66) were associated with decreased odds of RTW. Of the 23 OHCA survivors that participated in the more detailed RTW telephone-interview, 87% RTW. Flexible work hours or modified duties were offered to 74% of participants. Fatigue was the most frequently reported barrier to RTW. CONCLUSION: This is the largest study to collectively examine factors associated with RTW among survivors of OHCA. Although larger qualitative studies are needed, our findings highlight which patients are at risk of not RTW and who may benefit from targeted rehabilitation strategies.
