Ligamentoplasty in scapholunate instability: short-term results of the "all dorsal scapholunate repair" technique.

Injury to the scapholunate complex is the cause of scapholunate instability which can lead to radiocarpal and medio-carpal osteoarthritis. Several ligamentoplasty techniques have been reported for the treatment of chronic scapholunate instability before the osteoarthritis stage. The objective of this study was to assess the short-term results of an "all dorsal scapholunate repair" ligamentoplasty. We report the clinical, radiological and functional results of a retrospective study including 21 patients, operated between June 2019 and December 2020 for a stage 3 or 4 scapholunate instability according to the Garcia Elias classification. With a follow-up of 14.2 months, the pain was 0.1/10 according to the VAS at rest and 4/10 during exercise. Wrist strength was measured at 65% of the opposite side. The flexion-extension range of motion was 105°. Radiologically, there was a reduction of the diastasis and scapholunate angle. Osteolysis areas around the anchors were described in 47% of patients. The mean QuickDASH was 29.2/100, PRWE 24/100 and Mayo wrist score 67.8/100. Eighty-one percent of patients were satisfied. Seventeen patients had returned to work 5.2 months postoperatively. In the case of work-related injury, the functional scores were poorer, with a delayed return to work. This technique provides encouraging results in the short term. Most patients were improved compared to preoperative state. The work-related injury appears to be a poor prognostic factor. A longer-term study is imperative to confirm the maintenance over time of the correction of carpal malalignment and the evolution of the osteolysis areas.Level of evidence: Level IV Retrospective study.

Risk of non-medical drug overdose following prescription of opioids post-injury: A retrospective cohort study.

Background: There has been increasing scrutiny of opioid prescribing following injury because of concerns that prescribed opioids may contribute to addiction and overdose. This study aimed to better understand the relationship between injury, opioids prescribed before and after injury, and non-medical drug poisoning. Data and methods: Working age (15 to 65 years old) residents of British Columbia's Fraser Health region with an injury that involved an emergency department visit were included. Factors examined included the prescription of opioid and opioid agonist therapy (OAT) medications before and after injury, age, sex, work-related injuries, and socioeconomic status, as well as how they were associated with non-medical drug poisoning risk and post-injury prescriptions. Results: Opioid-naive individuals (those without an opioid prescription captured before their injury) who were prescribed OAT medication-a marker of opioid use disorder-following their injury had a higher risk of subsequent non-medical drug poisoning (Hazard ratio (HR): 21.4 to 22.4 compared with opioid-naive individuals without an opioid or OAT prescription). Post-injury opioid prescription in these individuals increased poisoning risk (HR: 1.27 compared with those without a prescription). Being of male sex (HR: 1.80), being younger (HR: 0.76 for every 10-year increase in age) and living in the lowest-income neighbourhoods (HR: 1.44 compared with the middle quintile) increased poisoning risk. Compared with injuries sustained outside of work, work-related injuries reduced risk (HR: 0.62). Interpretation: Among a cohort of British Columbians visiting emergency departments following an injury, opioid prescribing in patients who were opioid-naive appears to be a minor contributor to non-medical drug poisoning, particularly when compared with other patient factors, such as being male, being younger and having a low socioeconomic status.

Sleep disturbances and disability following work-related injury and illness: Examining longitudinal relationships across three follow-up waves.

Despite the high burden of sleep disturbances among the general population, there is limited information on prevalence and impact of poor sleep among injured workers. This study: (a) estimated the prevalence of sleep disturbance following work-related injury; and (b) examined the longitudinal association between sleep disturbances and disability/functioning, accounting for reciprocal relationships and mental illness. Longitudinal survey data were collected from workers' compensation claimants with a time-loss claim in Victoria, Australia (N = 700). Surveys were conducted at baseline, 6 months and 12 months. Sleep disturbance was measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire. Disability/functioning was based on self-reported activity limitations, participation restrictions and emotional functioning. Path models examined the association between disability/functioning and sleep. Mean sleep disturbance T-scores were 55.2 (SD 11.4) at 6 months, with 36.4% of the sample having a T-score of 60+. Longitudinal relationships were observed between disability (specifically, emotional functioning) and sleep disturbances across successive follow-up waves. For example, each unit increase in T2 emotional functioning (five-point scale) was associated with a 1.1 unit increase in T3 sleep disturbance (approximately 29-76 scale). Cross-lagged path models found evidence of a reciprocal relationship between disability and sleep, although adjustment for mental illness attenuated the estimates to the null. In conclusion, sleep disturbances are common among workers' compensation claimants with work injuries/illnesses. Given the links between some dimensions of disability, mental health and sleep disturbances, the findings have implications for the development of interventions that target the high prevalence of sleep problems among working populations.

To what extent is severe osteoarthritis preventable? Occupational and non-occupational risk factors for knee and hip osteoarthritis.

OBJECTIVES: To explore the relative contribution of cumulative physical workload, sociodemographic and lifestyle factors, as well as prior injury to hospitalization due to knee and hip OA. METHODS: We examined a nationally representative sample of persons aged 30-59 years, who participated in a comprehensive health examination (the Health 2000 Study). A total of 4642 participants were followed from mid-2000 to end-2015 for the first hospitalization due to knee or hip OA using the National Hospital Discharge Register. We examined the association of possible risk factors with the outcome using a competing risk regression model (death was treated as competing risk) and calculated population attributable fractions for statistically significant risk factors. RESULTS: Baseline age and BMI as well as injury were associated with the risk of first hospitalization due to knee and hip OA. Composite cumulative workload was associated with a dose-response pattern with hospitalizations due to knee OA and with hospitalizations due to hip OA at a younger age only. Altogether, prior injury, high BMI and intermediate to high composite cumulative workload accounted for 70% of hospitalizations due to knee OA. High BMI alone accounted for 61% and prior injury only for 6% of hospitalizations due to hip OA. CONCLUSION: Our results suggest that overweight/obesity, prior injury and cumulative physical workload are the most important modifiable risk factors that need to be targeted in the prevention of knee OA leading to hospitalization. A substantial proportion of hospitalizations due to hip OA can be reduced by controlling excess body weight.

Occupational radiation exposure and excess additive risk of cataract incidence in a cohort of US radiologic technologists.

OBJECTIVES: Previous analyses of cataract in radiation-exposed populations have assessed relative risk; radiogenic excess additive risk (EAR), arguably of more public health importance, has not been estimated. Previous analysis of a large prospective cohort of US radiologic technologists (USRT) quantified excess relative risk of cataract in relation to occupational radiation dose. We aim to assess EARs of cataract. METHODS: We estimated EARs of cataract/cataract surgery in the USRT cohort using generalised additive models in relation to occupational radiation exposure, and assessed risk modification by a priori-selected cataract risk factors (diabetes, body mass index, smoking, race, sex, birth-year, ultraviolet B (UVB) radiation exposure). RESULTS: There were 11 345 cataract diagnoses and 5440 of cataract surgery during 832 462 and 888 402 person-years of follow-up, respectively. Cumulative occupational radiation exposure was associated with self-reported cataract, but not with cataract surgery, with EAR/104 person-year Gy=94 (95% CI: 47 to 143, p<0.001) and EAR/104 person-year Gy=13 (95% CI: <0 to 57, p=0.551), respectively. There was marked (p<0.001) variation of EAR by age and by diabetes status, with risk higher among persons ≥75 years and diabetics. There were indications of elevated risk among those with higher UVB radiation (p=0.045), whites (p=0.056) and among those with higher levels of cigarette smoking (p=0.062). Elevated additive risk was observed for estimated occupational radiation eye-lens doses <100 mGy (p=0.004) with no dose-response curvature (p=0.903). CONCLUSIONS: The elevated additive risks associated with low-dose radiation, if confirmed elsewhere, have important public health and clinical implications for radiation workers as well as regulatory measures.

Influence of work organization and work environment on missed work, productivity, and use of pain medications among construction apprentices.

BACKGROUND: Construction is among the most dangerous industries. In addition to traditional hazards for workplace injury and illness, other threats to health and well-being may occur from work organization and work environment factors, including irregular employment, long commutes, long work hours, and employer policies regarding health and safety. These nontraditional hazards may affect work and health outcomes directly, or through effects on health behaviors. The cumulative impacts of both traditional and nontraditional hazards on health-related outcomes among construction workers are largely unknown. METHODS: We conducted a survey among apprentice construction workers to identify relationships between work organization and environmental factors with five outcomes of economic relevance to employers: missed work due to work-related injury, missed work due to any pain or injury, self-reported workability, health-related productivity, and use of prescription medications for pain. RESULTS: A total of 963 surveys were completed (response rate 90%) in this young (mean age 28) working cohort. Multivariate Poisson regression models found associations between the outcomes of interest and multiple work factors, including job strain, safety behaviors of coworkers, and mandatory overtime. Univariate analysis showed additional associations, including precarious work, and supervisor support for safety. CONCLUSIONS: Findings from this cross-sectional study suggest that work organization and environment factors influence health and work outcomes among young construction trade workers. Future work with longitudinal data will examine the hypothesized paths between work factors, health behaviors, health outcomes, and work outcomes.

Increased overall and cause-specific mortality associated with disability among workers' compensation claimants with low back injuries.

BACKGROUND: Mortality tends to be higher among people who do not work than among workers, but the impact of work-related disability on mortality has not been well studied. METHODS: The vital status through 2015 was ascertained for 14 219 workers with an accepted workers' compensation claim in West Virginia for a low back injury in 1998 or 1999. Mortality among the cohort compared with the West Virginia general population was assessed using standard life table techniques. Associations of mortality and disability-related factors within the cohort were evaluated using Cox proportional hazards regression. RESULTS: Compared to the general population, mortality from accidental poisoning was significantly elevated among the overall cohort and lost-time claimants. Most deaths from accidental poisoning in the cohort were due to drug overdoses involving opioids. Mortality from intentional self-harm was also significantly elevated among lost-time claimants. In internal analyses, overall mortality and mortality from cancer, heart disease, intentional self-harm, and drug overdoses involving opioids was significantly associated with lost time. Overall mortality and mortality from drug overdoses involving opioids were also significantly associated with amount of lost time, permanent partial disability, and percent permanent disability. Heart disease mortality was also significantly associated with the amount of lost time. CONCLUSIONS: The results suggest that disability itself may impact mortality risks. If confirmed, these results reinforce the importance of return to work and other efforts to reduce disability.

Penetrating Thoracic Injury and Fatal Aortic Transection From the Barb of a Stingray.

Stingrays are found in open waters and are also kept in exhibits in many aquariums throughout the world. They are generally nonaggressive creatures by nature, but they can inflict injuries with their spines if provoked. We present a case of a 62-y-old diver who was pierced in the chest by the barb of a stingray while transferring the animal to another tank as part of his work in a public aquarium. He was rescued immediately from the tank but was found to be in cardiac arrest. Bystander cardiopulmonary resuscitation was promptly initiated by his colleagues. He was rapidly evacuated to the nearest emergency department, where he was noted to be in pulseless electrical activity. A single puncture wound was noted over the right second intercostal space, with the spine of the stingray still impaled in the chest. Trauma surgeons were activated promptly, and resuscitation was continued based on advanced cardiac and trauma life support guidelines, which included ongoing cardiopulmonary resuscitation, securing the airway, and emergency blood transfusion. An emergency department thoracotomy was performed, but despite aggressive resuscitation the thoracic injury was fatal. An autopsy revealed transection of the aorta by an impaled barb. We present a review of stingray injuries and suggest a general approach to management.

Community acquired pressure injuries in a work-related spinal cord injury population: Problem characterization and assessment of a working solution.

BACKGROUND: To characterize the problem of community-acquired pressure injuries (CAPIs) in a work-related spinal cord injury (SCI) population in Canada and assess the benefits of a person-centered solution. Characterization of the problem and a solution, albeit in an insured Worker's Compensation Board of British Columbia (WorkSafeBC) cohort, may inform the supply of solutions in the larger SCI population with disparate access to healthcare. METHODS: For this observational study, data on 244 WorkSafeBC clients, who received an intervention featuring pressure injury (PI) assessment between 2011 and 2015, were used to characterize the problem. Data on observed injuries, risk, referrals, and outcomes were linked to healthcare service claims. Employing an activity-based costing methodology, total expenditures on attributed services were calculated for clients with 1 or more PIs. Intervention cost and benefits from the insurer's perspective are considered. RESULTS: 84 of 244 clients had 1 or more PIs at assessment, with attributed mean cost of $56,092 in 2015 Canadian dollars (CAD). Mean cost by PI severity range from $9580 to $238,736. At an intervention cost of $820,618, detection of less severe injuries provided an opportunity to prevent progression and achieve $3 million in cost avoidance. Follow-up data suggest reasonable returns. Reductions in the incidence, number, and risk of pressure injuries were also observed. CONCLUSIONS: The analysis establishes the cost of CAPIs in a Canadian-based work-related SCI population and suggests preventative and early intervention is not only feasible but also practical. Results are relevant to decisions regarding the use of proactive prevention-based treatment models as opposed to reactive, solutions in the larger SCI population.

Characteristics of Thoraco-Abdominal Injuries - A Series of Three Cases.

The enlarged number of powerful vehicles in our country led to an increased speed of travel and hence the high number of traffic accidents with severe consequences, even death. Along with polytrauma caused by occupational accidents, these types of traumas require complex and often multidisciplinary surgical therapy against the clock, which places the surgeon in front of situations that are not found in the everyday practice. Injuries involving damage to the thoracic-phreno-abdominal region fall into this specific category that we have chosen to discuss in the present work. We will further present three clinical cases of patients with thoraco-phreno-abdominal injuries produced by different mechanisms. A work-accident wound produced by an angle grinder, causing left thoracoabdominal injuries; a polytrauma caused by a road accident, with a thoraco-phreno abdominal wound produced by a piece of wood that penetrated obliquely through the right thorax, in the 5th and 6th intercostal spaces, crossed the right lower lung lobe, the diaphragm, the 7th liver segment, and stopped in the right posterior costal grid, and a polytrauma following a fall from a height, with a torn diaphragm and mesentery.

Relationship between early prescription dispensing patterns and work disability in a cohort of low back pain workers' compensation claimants: a historical cohort study.

OBJECTIVES: To examine and compare whether dispensing of prescription opioids, non-steroidal anti-inflammatory drugs (NSAIDs) and skeletal muscle relaxants (SMRs) within 8 weeks after a work-related low back pain (LBP) injury is associated with work disability. METHODS: A historical cohort study of 55 571 workers' compensation claimants with LBP claims in British Columbia from 1998 to 2009 was conducted using linked compensation, dispensing and healthcare data. Four exposures were constructed to estimate the effect on receipt of benefits and days on benefits 1 year after injury: drug class(es) dispensed, days' supply, strength of opioids dispensed and average daily morphine-equivalent dose. RESULTS: Compared with claimants receiving NSAIDs and/or SMRs, the incidence rate ratio (IRR) of days on benefits was 1.09 (95% CI 1.04 to 1.14) for claimants dispensed opioids only and 1.26 (95% CI 1.22 to 1.30) for claimants dispensed opioids with NSAIDs and/or SMRs. Compared with weak opioids only, the IRR for claimants dispensed strong opioids only or strong and weak opioids combined was 1.21 (95% CI 1.12 to 1.30) and 1.29 (95% CI 1.20 to 1.39), respectively. The incident rate of days on benefits associated with each 7-day increase in days supplied of opioids, NSAIDs and SMRs was 10%, 4% and 3%, respectively. Similar results were seen for receipt of benefits, though effect sizes were larger. CONCLUSIONS: Findings suggest provision of early opioids leads to prolonged work disability compared with NSAIDs and SMRs, though longer supplies of all drug classes are also associated with work disability. Residual confounding likely partially explains the findings. Research is needed that accounts for prescriber, system and workplace factors.

Acceptability and Feasibility of a Shared Decision-Making Model in Work Rehabilitation: A Mixed-Methods Study of Stakeholders' Perspectives.

Purpose To establish the acceptability and feasibility of implementing a shared decision-making (SDM) model in work rehabilitation. Methods We used a sequential mixed-methods design with diverse stakeholder groups (representatives of private and public employers, insurers, and unions, as well as workers having participated in a work rehabilitation program). First, a survey using a self-administered questionnaire enabled stakeholders to rate their level of agreement with the model's acceptability and feasibility and propose modifications, if necessary. Second, eight focus groups representing key stakeholders (n = 34) and four one-on-one interviews with workers were conducted, based on the questionnaire results. For each stakeholder group, we computed the percentage of agreement with the model's acceptability and feasibility and performed thematic analyses of the transcripts. Results Less than 50% of each stakeholder group initially agreed with the overall acceptability and feasibility of the model. Stakeholders proposed 37 modifications to the objectives, 17 to the activities, and 39 to improve the model's feasibility. Based on in-depth analysis of the transcripts, indicators were added to one objective, an interview guide was added as proposed by insurers to ensure compliance of the SDM process with insurance contract requirements, and one objective was reformulated. Conclusion Despite initially low agreement with the model's acceptability on the survey, subsequent discussions led to three minor changes and contributed to the model's ultimate acceptability and feasibility. Later steps will involve assessing the extent of implementation of the model in real rehabilitation settings to see if other modifications are necessary before assessing its impact.

Man-In-The-Barrel Syndrome: Acute bilateral brachial plexopathy after recurrent microtrauma.

The presence of brachial diplegia despite the normal muscular strength of the lower extremities is called the man-in-the-barrel syndrome (MIBS). Although this rare syndrome often occurs due to the bilateral supratentorial brain lesions, it may also rarely occur as a result of infratentorial causes. In this report, we describe a case presenting with MIBS of which etiological underlying cause was bilateral brachial plexopathy developed secondarily to recurrent microtrauma. A 51-year-old male patient presented to our clinic with complaints of pain and weakness on both arms. After electrodiagnostic examination, bilateral brachial plexopathy was identified. The findings of the patient improved following methylprednisolone therapy. It is very important to determine the treatable causes of this syndrome at an early stage.

Gender differences in limited duty time for lower limb injury.

Background: Among active-duty military personnel, lower limb musculoskeletal injuries and related conditions (injuries) frequently arise as unintended consequences of physical training. These injuries are particularly common among women. The practical impact of such injuries on temporary military occupational disability has not been estimated with precision on a large scale. Aims: To determine the proportion of service time compromised by limited duty days attributable to lower limb injuries, characterize the time affected by these limitations in terms of specific lower limb region and compare the limited duty time between male and female soldiers. Methods: Administrative data and individual limited duty assignments (profiles) were obtained for active-duty US Army personnel who served in 2014. Lower limb injury-related profiles were used to calculate the percent of person-time requiring duty limitations by gender and body region. Results: The study group was 568 753 soldiers of whom 14% were women. Nearly 13% of service days for active-duty US Army soldiers required limited duty for lower limb injuries during 2014. Knee injuries were responsible for 45% of those days. Within integrated military occupations, female soldiers experienced 27-57% more time on limited duty for lower limb injuries compared with men. Conclusions: The substantial amount of limited duty for lower limb musculoskeletal injuries among soldiers highlights the need for improvement in training-related injury screening, prevention and timely treatment with particular attention to knee injuries. The excessive impact of lower limb injuries on female soldiers' occupational functions should be a surveillance priority in the current environment of expanding gender-integrated training.

The preventable burden of work-related ill-health.

Background: The fraction of ill-health overall attributable to occupational conditions has not been extensively evaluated, thus contributing to the perception of a lesser relevance of education and research in occupational health in respect to other fields of medical research and practice. Aims: To assess the relevance of work-related conditions on the aetiology of human ill-health in different health domains. Methods: We extracted the risk estimates associated with heritability and with occupational risk factors for chronic lymphocytic leukaemia (CLL), major depressive disorder (MDD) and long QT syndrome (LQTS) from 13 published international reports. The selection criteria for the eligible studies were: genome-wide studies, or studies of the occupational risk factors associated with one of the three diseases of interest. We calculated and compared the respective population attributable fraction for the combined occupational risk factors, and for heritability. Results: We estimated that occupational risk factors would account for 12% (95% confidence interval (CI) 4-19) of CLL, 11% (95% CI 7-15) of MDD and 10% (95% CI 2-13) of LQTS burden in the general population. The corresponding figures for heritability would be 16% (95% CI 11-22), 28% (95% CI 20-5) and 17% (95% CI 7-27). Conclusions: More efforts in capacity building and research in occupational health are warranted aiming to prevent ill-health and to preserve a productive life for the ageing work population.

Farming characteristics and self-reported health outcomes of Irish farmers.

Background: Irish farmers represent a 'high-risk' group for non-communicable diseases, which, arguably, pose a greater occupational health challenge for farmers. To date, there has been little exploration of the farming characteristics associated with farmers' poor health outcomes. Aims: To examine the relationship between farming and male farmers' self-reported health outcomes and to compare the study findings to national health studies to explore which factors specifically are associated with Irish farmers' poorer health outcomes relative to the general population. Methods: This cross-sectional survey research used self-reported quantitative data on the health outcomes and health behaviours of male farmers from the South-East of Ireland. Data were entered into SPSS and descriptive and binary regression techniques were used for data analysis. Results: There were 314 participants (99% response rate). Age, full-time farming and dairy farming significantly impacted self-reported health outcomes and health behaviours. There was a high prevalence of self-reported arthritis compared with the national average of Irish males. 'Younger' farmers (<45 years) were more likely to engage in harmful health behaviours such as smoking and 'binge-drinking' one or more times per week. Conclusions: This study identified self-reported patterns of risky lifestyle behaviours among particular subgroups of Irish farmers for whom targeted health interventions are warranted. Interventions are particularly important for younger farmers who may see themselves as invincible and impregnable to ill-health.

Depressive, anxiety and post-traumatic stress disorders at six years after occupational injuries.

The aim of this study is to determine the prevalence rates of depressive, anxiety and PTSDs, and the risk factors for psychological symptoms at 6 years after occupational injury. This longitudinal study followed workers who were occupationally injured in 2009. Psychological symptoms and return to work were assessed at 3 and 12 months after injury. Injured workers who had completed the initial questionnaire survey at 3 or 12 months after injury were recruited. A self-administered questionnaire was mailed to the participants. For workers with high Brief Symptom Rating Scale and Post-traumatic Symptom Checklist scores, an in-depth psychiatric evaluation was performed using the Mini-international Neuropsychiatric Interview. A total of 570 workers completed the questionnaire (response rate, 28.7%). Among them, 243 (42.6%) had high psychological symptom scores and were invited for a phone interview; 135 (55.6%) completed the interview. The estimated rates of major depression and post-traumatic stress disorder (PTSD)/partial PTSD were 9.2 and 7.2%, respectively, and both these rates were higher at 6 years after injury than at 12 months after injury (2.0 and 5.1%). After adjustment for family and social factors, the risk factors for high psychological scores were length of hospitalization immediately after injury, affected physical appearance, repeated occupational injuries, unemployment, and number of quit jobs after the injury. At 6 years after occupational injury, the re-emergence of psychiatric disorders was observed. Relevant factors for poor psychological health were severity of injury and instability of work. Periodic monitoring of psychological and physical health and economic stability are warranted.

Marginal structural modelling of associations of occupational injuries with voluntary and involuntary job loss among nursing home workers.

OBJECTIVES: Qualitative studies have highlighted the possibility of job loss following occupational injuries for some workers, but prospective investigations are scant. We used a sample of nursing home workers from the Work, Family and Health Network to prospectively investigate association between occupational injuries and job loss. METHODS: We merged data on 1331 workers assessed 4 times over an 18-month period with administrative data that include job loss from employers and publicly available data on their workplaces. Workers self-reported occupational injuries in surveys. Multivariable logistic regression models estimated risk ratios for the impact of occupational injuries on overall job loss, whereas multinomial models were used to estimate OR of voluntary and involuntary job loss. Use of marginal structural models allowed for adjustments of multilevel lists of confounders that may be time varying and/or on the causal pathway. RESULTS: By 12 months, 30.3% of workers experienced occupational injury, whereas 24.2% experienced job loss by 18 months. Comparing workers who reported occupational injuries to those reporting no injuries, risk ratio of overall job loss within the subsequent 6 months was 1.31 (95% CI 0.93 to 1.86). Comparing the same groups, injured workers had higher odds of experiencing involuntary job loss (OR 2.19; 95% CI 1.27 to 3.77). Also, compared with uninjured workers, those injured more than once had higher odds of voluntary job loss (OR 1.95; 95% CI 1.03 to 3.67), while those injured once had higher odds of involuntary job loss (OR 2.19; 95% CI 1.18 to 4.05). CONCLUSIONS: Despite regulatory protections, occupational injuries were associated with increased risk of voluntary and involuntary job loss for nursing home workers.

Electrical injury in relation to voltage, "no-let-go" phenomenon, symptoms and perceived safety culture: a survey of Swedish male electricians.

PURPOSE: Professional electricians are highly subjected to electrical injuries. Previous studies describing symptoms after electrical injury have not included people with less severe initial injuries. The purpose of the present study was to describe symptoms at different time points after electrical injury, the impact of "no-let-go" phenomenon and different electrical potential [high voltage (HV) vs. low voltage (LV)], and the safety culture at the workplace. METHODS: A retrospective survey was conducted with 523 Swedish electricians. Two questionnaires were issued: the first to identify electricians who had experienced electrical injury and the second to gain information about symptoms and safety culture. Self-reported symptoms were described at different time points following injury. Symptoms for HV and LV accidents were compared. Occurrence or nonoccurrence of "no-let-go" phenomenon was analysed using two-tailed Chi-2. Safety culture was assessed with a validated questionnaire. RESULTS: Nearly all reported having symptoms directly after the injury, mainly paraesthesia and pain. For the first weeks after injury, pain and muscle weakness dominated. The most frequently occurring symptoms at follow-up were pain, muscle weakness and loss of sensation. HV injuries and "no-let go" phenomenon were associated with more sustained symptoms. Deficiencies in the reporting routines were present, as well as shortage of preventive measures. CONCLUSION: The results indicate that symptoms are reported also long time after an electrical injury and that special attention should be paid to HV injuries and "no-let go" accidents. The workplace routines to reduce the number of work-related electrical injuries for Swedish electricians can be improved.
