    The Correlates of Post-Traumatic Stress Disorder in Ambulance Personnel and Barriers Faced in Accessing Care for Work-Related Stress
    (2022-02-11) Ntatamala, Itumeleng; Adams, Shahieda
    We investigated factors associated with increased risk for post-traumatic stress disorder (PTSD) in ambulance personnel and the barriers faced in accessing support for work-related stress (WRS). A cross-sectional study of 388 ambulance personnel used self-administered questionnaires to assess for PTSD and level of occupational stressors: Impact of Event Scale-Revised, Emergency Medical Services (EMS) Critical Incident Inventory, EMS Chronic Stress Questionnaire, SF-36 Quality of Life and the Connor–Davidson Resilience Scale. The prevalence of PTSD in the study population was 30%. The participants were predominantly female (55%), with a median age of 38 (IQR; 31–44) years. PTSD was associated with smoking (OR = 1.76, 95% CI: 1.05–2.95), illicit drug use (OR = 16.4, 95% CI: 1.87–143.86) and problem drinking (OR = 3.86, 95% CI: 1.80–8.23). A self-reported mental health condition (OR = 3.76, 95% CI: 1.96–7.21), being treated for a medical condition (OR = 1.95, 95% CI: 1.22–3.11), exposure to critical incident stress (OR = 4.27, 95% CI: 2.24–8.15) and chronic WRS (OR = 4.46, 95% CI: 1.93–10.31) were associated with PTSD risk. Barriers to seeking help included concerns that services were not confidential and the negative impact on the participant’s career. The increased levels of WRS, strong associations with substance use and barriers to accessing care offer starting points for workplace interventions to reduce the impact of PTSD in ambulance personnel.

    Determinants of Fractional exhaled Nitric Oxide (FeNO) levels in occupational asthma in different occupational settings
    (2025) Mfune, Phinias Harris Katolora; Jeebhay, Mohamed; Baatjies, Roslynn
    Background: Fractional exhaled nitric oxide (FeNO) offers a potential tool for screening and surveillance of workers at risk of occupational respiratory allergy and asthma. Objective: This study evaluated determinants of FeNO in workers at risk of occupational respiratory allergy and asthma in diverse industries in southern Africa. Methodology: Data were analysed from cross-sectional epidemiological studies of bakery, fruit farming, spice milling, poultry farming, wood processing and healthcare industries. All studies used the modified ECRHS questionnaire, assessed atopy using Phadiatop, allergen specific sensitization (sIgE) and NIOX MINO.

    Predictors of post-traumatic stress disorder among ambulance personnel in the western cape province
    (2021) Ntatamala, Itumeleng Mmoko Theophelus; Adams, Shahieda
    Objective: To determine the factors associated with an increased risk for PTSD in ambulance personnel and the barriers faced in accessing support for work related stress (WRS). Methods: A cross-sectional study of voluntary participants comprising 388 ambulance personnel was conducted. Participants completed self-administered questionnaires: Impact of Event Scale-Revised (IES-R), EMS Critical Incident Inventory (CII), EMS Chronic Stress Questionnaire (EMSCSQ), SF-36 Quality of Life questionnaire (SF-36) and Connor-Davidson Resilience Scale (CD-RISC) which were used to assess PTSD and level of occupational stressors. Results: The prevalence of PTSD in the study population was 30%. Participants were predominantly female (55%), median age 38 (IQR; 31 - 44) years with a professional qualification (83%). Those with PTSD were more likely current smokers (OR=1.76, 95% CI: 1.05 - 2.95), current illicit drug users (OR=16.4, 95% CI: 1.87 - 143.86) and problem drinkers (OR=3.86, 95% CI: 1.80 - 8.23). A self-reported mental health condition (OR=3.76, 1.96 - 7.21), being treated for a medical condition (OR=1.95, 1.22 - 3.11), exposure to chronic WRS (OR=1.05, 1.04 - 1.07) and high critical incident stress score (OR=1.03, 1.02 - 1.04) were positively associated with PTSD risk. Barriers to seeking help for WRS included concerns that services were not confidential, and that the participant's career would be negatively affected. Conclusion: The PTSD prevalence in ambulance personnel is considerably higher than that found in previous studies conducted among this occupational group in the Western Cape. Identified risk factors should inform interventions designed to support ambulance personnel and a greater focus on addressing barriers to accessing care is needed.
