Cardiovascular Disease Risk Screening for Commercial Drivers Examined in Occupational Practice: Implementing Evidence-Based Practice to Champion the Health of Essential Workers

BACKGROUND

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality in the United States, with 20% of deaths in adults under age 65. Commercial drivers have an increased CVD incidence rate of 50% compared to 30% for the general population, yet one third of drivers will not be screened for risk factors due to a lack of insurance or primary care. With approximately 3.5 million commercial drivers nationally and correlation of CVD to increased motor vehicle accidents, fatalities, and excessive healthcare costs, addressing the care gap for this high-risk population is imperative.

METHODS

An evidence-based practice (EBP) project synthesized the literature and implemented CVD risk screening for commercial drivers examined in an occupational practice setting. Using the non-laboratory Framingham CVD risk score calculator, over 90% of drivers were screened during mandated medical examinations and provided education regarding modifiable risk factors during a 2-month period.

FINDINGS

Over 40% of commercial drivers were at high risk for CVD with 25% uninsured and 32% without primary care. The average CVD risk score was twice the general population's risk score, with obesity, hypertension, and smoking being the most common risk factors discussed.

CONCLUSIONS/APPLICATION TO PRACTICE

Incorporating CVD risk screening and education during opportune encounters is logical, efficient, and financially prudent. The EBP change supports occupational professionals' standards, and ongoing review of CVD screening guidelines with integration into practice provides health promotion and promotes public safety for these essential workers.

Refractive errors among commercial drivers

Purpose

To determine the pattern of refractive error among commercial drivers in north India.

Methods

Descriptive study with convenient sampling conducted among commercial drivers of north India.

Results

A total of 213 (75.8%) heavy-vehicle and 68 (24.2%) light-vehicle drivers were screened for eye diseases. Refractive error for distance was reported in 44 (15.7%; 95% CI: 11.6-20.4) drivers. Hyperopia was reported in 23 (8.2%; 95% CI: 5.2-12) drivers, followed by myopia in 15 (5.3%; 95% CI: 3-8.6) drivers and astigmatism in six (2.1%; 95% CI: 0.7-4.5) drivers. Presbyopia was reported in 157 (55.8%) drivers. Dry eye was reported in 70 (24.9%), stereo deficiency in 77 (27.4%), and color vision deficiency in 11 (3.9%) drivers. Three drivers were diagnosed with cataract, and two were referred for retina evaluation.

Conclusion

Hyperopia in both eyes was the most common refractive error. Dry eye disease and color vision deficiency were also reported. Most of the drivers were not using spectacles for refractive error correction. Due to their mobile nature, drivers with cataract and retina diseases did not turn up for follow-up.

Factors contributing to road crashes among commercial vehicle drivers in the Kintampo North Municipality, Ghana in 2017

Objective

The study assessed driver, vehicular and road-related factors associated with road crashes (RC) in the Kintampo North Municipality.

Design

Cross-sectional study

Setting

Kintampo North Municipality

Data source

Demographics, vehicular and road usage information on registered drivers at Ghana Private Road and Transport Union (GPRTU) and Progressive Transport Owners Association (PROTOA) in Kintampo North Municipality

Main outcome

involvement in road crashes and related factors

Result

A total of 227 drivers were approached for this study. None of them declined participation. They were all males. Most were between 28–37 years (30%). The proportion of drivers that reported RC ever involvement in at least one RC was 55.5% (95% CI: 8.0%, 62.1%). In the bivariate analysis, drink and drive changed lane without signalling, ever bribed police officer, drove beyond the maximum speed limit, paid a bribe at DVLA for driving license, violation of traffic signals were found to be associated with RC involvement (p<0.05). Drivers who violated traffic signals had 2.84 odds of being involved in road crashes compared to those who did not [aOR; 2.84 (95%CI:1.06,7.63)]

Conclusion

The proportion of drivers ever involved in road crashes was high. The major factor that is associated with RC involvement was a violation of the traffic light signals. Continuous driver education and enforcement of road traffic regulations by the appropriate authorities could curb the road crash menace in the Municipality.

Mobile phone use among commercial drivers in Ghana: An important threat to road safety

Background

Ghana passed a law in 2012 banning the use of mobile phones while driving. However, data on compliance to the law has been lacking.

Objective

To examine factors associated with mobile phone use while driving among Ghanaian commercial drivers.

Methods

A survey was conducted among 627 commercial drivers (98.0% response rate). Bivariate and multivariate logistic regressions were performed to determine how a priori covariates influenced commercial drivers' use of phones while driving. The covariates included driver age, education, driving route distance, driving under the influence (DUI), and knowledge that phone use during driving causes distraction.

Results

Respondents were aware of the law (94.7%) but compliance was low (38%). Drivers who did not believe that cell phone use contributed to crash risk were more likely to report distracted driving (AOR 2.02,95%CI 1.05-3.9). Drivers who had completed primary (AOR 4.49,95%CI 1.14-17.78) or at least senior high school (AOR 6.89,95%CI 1.5-31.59) had increased odds of using the phone while driving, compared to those having no formal education. Drivers with 6-10 years (AOR 2.00,95%CI 1.00-3.98) or >10 years driving experience (AOR 2.87,95%CI 1.24-6.62) were more likely to report distracted driving compared to those with ≤5 years' experience. Drivers who travelled longer distances were more likely to report distracted driving (AOR 2.41,95%CI 1.23-4.71). Those who had never engaged in DUI were less likely to use the phone while driving (AOR 0.06,95%CI 0.01-0.43).

Conclusion

Future prevention efforts for distracted driving in Ghana will require targeted distracted driving enforcement and education for commercial drivers and their passengers.

Environmental and familial factors in drug use among commercial drivers in suburban public transport

Background:

A study was conducted in 2013 on the lack of accurate statistics on the environmental and family factors behind the use of drugs by drivers of public transport.

Materials and Methods:

Overall, 1176 drivers of buses, mini-buses, vans, all kinds of trucks, and cars were randomly selected proportionately according to the type of vehicles. The capture-recapture sampling method was used to determine the prevalence rate of drug use among commercial drivers. Trained experts collected data regarding the environmental and family factors behind the use of addictive drugs. Urinalysis was performed by the Rapid Test method (ACON, San Diego, USA). To providing descriptive and analytical statistics the Kruskal–Wallis and Mantel–Haenszel methods, logistic regression, and Chi-square tests were used.

Results:

The mean age of the drivers was 39.9 ± 9.7 years. The results of the experiment were positive in 14.1% of the drivers. A significant difference observed between addicted and nonaddicted drivers related to cold and heat (P < 0.001) and lack of facilities (P = 0.006) as the most influencing factors. The most important environmental factor was family poverty (P < 0.001), followed by marital status and its problems (P = 0.002), a large number of children (P = 0.006), and family disputes (P = 0.012). A family history of addiction was 2.5 times more among addicted drivers.

Conclusion:

Prevalence of addiction was 14.1%. Among the environmental factors, cold and heat, lack of facilities, family factors, and a family history of addiction greatly influenced addiction.

When should the driver with a history of substance misuse be allowed to return to the wheel? A review of the substance misuse section of the Australian national guidelines

Assessing fitness to drive in applicants with a historical or current substance use disorder presents a specific clinical challenge. The Australian guidelines require evidence of remission and absence of cognitive change when considering applications for re-licensing driver or individuals applying to reengage in safety-sensitive work. This paper reviews some of the clinical and biochemical indicators that determine whether a particular person is in 'remission' and meets the criteria for return to driving or other safety-sensitive occupation. It provides an overview of the challenges in establishing an evidence-based approach to determining fitness for safety critical activities. There is no internationally accepted definition of 'remission'. Review of the literature and examination of assessment protocols from other national jurisdictions are available for alcohol and the more important drugs of interest in road safety. Assessing fitness to drive when there is a history of substance misuse and/or substance use disorders is a complex issue that requires assessment of biomarkers, clinical findings and clinical assessment before the person returns to driving. We propose that hair testing provides a reliable and reproducible way to demonstrate remission and provide cost-effective monitoring. Standardised psychological tests could provide a reproducible assessment of the cognitive effects of drug use and suitability to resume driving. We recommend that AustRoads amend the national guidelines to reflect an evidence-based approach to assessing fitness to drive after conviction for offences related to alcohol and drug use.

A Descriptive Study of Musculoskeletal Injuries in Long-Haul Truck Drivers: A NIOSH National Survey

Long-haul truck drivers are significantly affected by musculoskeletal injuries with incidence rates 3.5 times higher than the national average. Yet, little is known about injuries that affect long-haul trucks drivers. In 2010, interviewers collected data from 1,265 long-haul truck drivers at 32 truck stops across the United States. These surveys were analyzed to describe all self-reported musculoskeletal injuries. Injuries to the arm (26.3%) and back (21.1%) were the two areas most reported in the survey. Musculoskeletal injuries were most often caused by falls (38.9%) and contact with an object or equipment (33.7%) resulting most commonly in sprains/strains (60%). This large scale survey highlights the significance of musculoskeletal injuries in long-haul truck drivers and suggests the need to develop interventions to prevent injuries and improve recovery once injuries occur.

Screening commercial drivers for obstructive sleep apnea: Validation of STOP-Bang questionnaire

OBJECTIVES

The main aim has been to examine psychometric properties of STOP-Bang (snoring, tiredness, observed apnea, high blood pressure, body mass index (BMI), age, neck circumference, male gender) scoring model (Serbian translation), an obstructive sleep apnea (OSA) screening tool, in a sample of commercial drivers.

MATERIAL AND METHODS

After formal translation, validation was performed on a sample of bus and truck drivers evaluating test-retest reliability, construct and criterion validity. Overnight polysomnography or cardiorespiratory polygraphy were used for OSA diagnosis purposes.

RESULTS

One hundred male participants, 24-62 years old, were included. STOP-Bang classified 69% as potential OSA patients. Polysomnography identified OSA in 57% of the sample. Test-retest reliability (Cohen's κ = 0.89) was adequate. STOP-Bang score was significantly correlated to apnea-hypopnea index (AHI) and OSA severity. Sensitivity was 100% for AHI ≥ 15, highest specificity was 53.5% (AHI ≥ 5).

CONCLUSIONS

STOP-Bang showed good measurement properties, supporting its further use in OSA screening of commercial drivers. Int J Occup Med Environ Health 2016;30(5):751-761.

Screening Commercial Vehicle Drivers for Obstructive Sleep Apnea: Tools, Barriers, and Recommendations

Obstructive sleep apnea (OSA) is a disorder characterized by a cessation of breathing during sleep, leading to poor sleep patterns and daytime somnolence. Daytime somnolence is of particular concern for commercial vehicle drivers, whose crash risk increases 50% with untreated OSA. The process of diagnosing and treating OSA in commercial drivers begins with effective and consistent screening. Therefore, the researchers screened drivers with both the STOP-Bang Questionnaire and the Obstructive Sleep Apnea Evaluation Worksheet (OSAEW) and compared the two tools. Drivers screening positive on the STOP-Bang Questionnaire, OSAEW, and both questionnaires were 28%, 23%, and 13%, respectively. Sleep study referrals were made for 50 drivers; 12 drivers were scheduled for sleep tests within 3 months. Health care provider referral rates for drivers screening at high risk (37%) and commercial driver monitoring rates (24%) were both low. Recommendations to improve OSA screening and testing practices include Federal Motor Carrier Safety Administration-mandated screening and referral guidelines, employee-facilitated sleep testing, and OSA awareness campaigns.

Effect of First Aid Education on First Aid Knowledge and Skills of Commercial Drivers in South West Nigeria

BACKGROUND

Prompt prehospital care is essential for improving outcomes of road crash victims; however, this service is sub-optimal in developing countries because Emergency Medical Services (EMS) are not readily available. Training of lay responders in first aid has been suggested as a means of filling this gap in settings with inadequate EMS. This study was conducted to determine the effect of first aid training on the first aid knowledge and skills of commercial drivers.

METHODS

A before-and-after study was conducted among 128 commercial drivers (62 intervention and 66 controls) selected by multi-stage sampling. Drivers' first aid knowledge and skills were assessed at baseline, immediate, and three months post-intervention. The intervention involved a 2-day training session in first aid. Repeated measures ANOVA was used to test for differences in respondents' pre- and post-intervention scores over the three assessment points.

RESULTS

Mean first aid knowledge scores for intervention drivers were 48.9% (SD=12.0), 57.8% (SD=11.2), and 59.2% (SD=9.0) at baseline, immediate, and three months post-intervention. Corresponding scores for the controls were 48.3% (SD=12.8), 39.2% (SD=15.3), and 46.8% (SD=15.3). Mean first aid skill scores for intervention drivers were 17.5% (SD=3.8), 80.7% (SD=8.3), and 72.3% (SD=16.8). Scores for control drivers were 16.5% (SD=4.5), 16.3% (SD=4.7), and 20.4% (SD=9.1), respectively. Repeated measures ANOVA showed significant differences in first aid knowledge and skills scores over the three phases. Independent t-test revealed significant differences in scores between the intervention and control groups post-intervention.

CONCLUSION

The training led to significant improvement in first aid knowledge and skills of intervention drivers. This confirms that lay responders can be trained in provision of first aid. The slight drop in skills scores, which occurred three months post-intervention, highlights the need for periodic refresher trainings to be conducted for the drivers in order to maintain the knowledge and skills acquired.

Work patterns, sleeping hours and excess weight in commercial drivers

BACKGROUND

Work and sleep patterns for commercial motor vehicle (CMV) drivers often include long working hours, shift work and diminished sleep duration and quality, which have been linked to overweight, obesity and other problems.

AIMS

To explore possible connections between work, sleep and obesity among CMV drivers.

METHODS

Survey and anthropometric data were collected from male long-haul CMV drivers in central North Carolina, USA, over a period of 6 months. Drivers' body mass index (BMI) was used as a measure of total body obesity and sagittal abdominal diameter (SAD) as a measure of central adiposity.

RESULTS

Among the 260 study subjects, mean BMI was 33.1 (64% were obese or morbidly obese) and mean SAD was 32.3cm, classifying 89% of drivers as being at high or very high cardiometabolic risk. About 83% of drivers worked an irregular daily schedule, 64% worked irregular total daily hours, 32% worked irregular days of the week and 46% reported getting <7h of sleep during work nights. Significant predictors of BMI included the number of hours worked daily (P < 0.05) and the age (P < 0.01) of the driver, while age was also a significant predictor for SAD (P < 0.05). Significant predictors of sleep quality included the extent of shift work (P < 0.05) and sleep duration (P < 0.001).

CONCLUSIONS

Work and sleep configurations appear to affect the weight status of CMV drivers. Shift work and sleep duration are both associated with the weight status of CMV drivers, and both appear to function as indicators of their sleep quality.

Surveying the Impact of Work Hours and Schedules on Commercial Motor Vehicle Driver Sleep

Background

Given the long hours on the road involving multiple and interacting work stressors (i.e., delivery pressures, irregular shifts, ergonomic hazards), commercial drivers face a plethora of health and safety risks. Researchers goal was to determine whether and to what extent long-haul trucker work schedules influence sleep duration and quality.

Methods

Survey and biometric data collected from male long-haul truck drivers at a major truckstop in central North Carolina over a six month period.

Results

Daily hours worked (mean = 11 hours, 55 minutes) and frequency of working over government-mandated daily HOS regulations (23.8% “frequently or always”) were statistically significant predictors of sleep duration. Miles driven per week (mean = 2,812.61), irregular daily hours worked (63.8%), and frequency of working over the daily hour limit (23.8% “frequently or always”) were statistically significant predictors of sleep quality.

Conclusion

Implications of findings suggest a comprehensive review of the regulations and operational conditions for commercial motor vehicle drivers be undertaken.

Obstructive sleep apnea and driving: A Canadian Thoracic Society and Canadian Sleep Society position paper

Untreated patients with obstructive sleep apnea (OSA) are at increased risk for motor vehicle collisions; however, it is unclear how this should be translated into fitness-to-drive recommendations. Accordingly, the Canadian Thoracic Society (CTS) Sleep Disordered Breathing Clinical Assembly and the Canadian Sleep Society (CSS) assembled a CTS-CSS working group to propose recommendations with regard to driving in patients with OSA. Recommendations for assessing fitness to drive in noncommercial drivers: 1. Severity of OSA alone is not a reliable predictor of collision risk and, therefore, should not be used in isolation to assess fitness to drive; 2. The severity of sleep apnea should be considered in the context of other factors to assess fitness to drive; 3. The decision to restrict driving is ultimately made by the motor vehicle licensing authority; however, they should take into account the information and recommendations provided by the sleep medicine physician and should follow provincial guidelines; 4. For patients prescribed continuous positive airway pressure (CPAP) therapy, objective CPAP compliance should be documented. Efficacy should also be documented in terms of reversing the symptoms and improvement in sleep apnea based on physiological monitoring; 5. For patients treated with surgery or an oral appliance, verification of adequate sleep apnea treatment should be obtained; and 6. A driver diagnosed with OSA may be recertified as fit to drive based on assessment of symptoms and demonstrating compliance with treatment. The assessment should be aligned with the provincial driver's license renewal period. Commercial vehicles: Assessment of fitness to drive should be more stringent for patients operating commercial vehicles. In general, the CTS-CSS working group was in agreement with the Medical Expert Panel recommendations to the Federal Motor Carrier Safety Administration in the United States; these recommendations were adapted for Canadian practitioners.

Obstructive sleep apnea in North American commercial drivers

The most common medical cause of excessive daytime sleepiness (EDS) is obstructive sleep apnea (OSA). Specifically, among an estimated 14 million US commercial drivers, 17-28% or 2.4 to 3.9 million are expected to have OSA. Based on existing epidemiologic evidence, most of these drivers are undiagnosed and not adequately treated. Untreated OSA increases the risk of vehicular crashes as documented in multiple independent studies and by meta-analysis. Therefore, identifying commercial drivers with OSA and having them effectively treated should decrease crash-related fatalities and injuries. Several strategies are available for screening and identifying drivers with OSA. The simplest and most effective objective strategies use body mass index (BMI) cutoffs for obesity. Functional screens are promising adjuncts to other objective tests. The most effective approach will likely be a combination of a good questionnaire; BMI measures; and a careful physician-obtained history complemented by a functional screen.
