Symptoms of post-traumatic stress disorder among first aid providers.

Background: Every year, large numbers of individuals are present or provide first aid in situations involving out-of-hospital cardiac arrest, injuries, or suicides. Little is known about the impact of providing first aid or witnessing a first aid situation, but research indicates that many first aid providers (FAP) experience persistent psychological difficulties. Here we aimed to assess the level of psychological impact of being a FAP. Methods: In this retrospective study, FAP attending follow-up were asked to complete the International Trauma Questionnaire (ITQ), which is a self-report diagnostic measure of post-traumatic stress disorder (PTSD) and complex post-traumatic stress disorder (CPTSD). We recorded endorsement of a symptom or functional impairment (score ≥ 2/4 on at least one of 18 items). Results: Of the 102 FAP in this study, 86 (84%) showed endorsement of a symptom or functional impairment. Common symptoms/functional impairments included being super-alert, watchful, or on guard; having powerful mental images; avoiding internal reminders or memories; and being affected in important parts of one's life. One-third had affected ability to work. Of the FAPs who attended follow-up more than one month after the incident (n = 32), 19% met the criteria for PTSD or CPTSD. Conclusions: The majority of FAPs have endorsement of a symptom or functional impairment. Some FAPs fulfil the criteria of PTSD. We suggest that follow-up should be offered by the EMS to all FAPs involved in incidents with an unconscious patient.

Hepatic steatosis is associated with anthropometry, cardio-metabolic disease risk, sex, age and urbanisation, but not with ethnicity in adult Kenyans.

OBJECTIVE: We aimed to determine the associations of non-alcoholic fatty liver disease (NAFLD) with cardio-metabolic risk factors for diabetes in adult Kenyans. METHODS: A cross-sectional study was undertaken among rural and urban Kenyans of different ethnic origin. Ultrasonography scanning (USS) methods were used for the assessment of hepatic fat accumulation for NAFLD assessment and abdominal fat distribution, and simple anthropometry measurements were performed. All participants underwent a 2-h oral glucose tolerance test, and biochemical, haemodynamic and lifestyle data were obtained. Multivariate logistic regression analyses were used to assess sex, age, residency and ethnic differences in the association between NAFLD and various metabolic parameters. RESULTS: In total, 743 individuals (59.1% women) with a mean age of 38.0 (range 18-68) years participated in the study. Overall, 118 individuals (15.9%) had NAFLD, of whom 94.1% had mild steatosis. Age >40 years was significantly associated with having NAFLD compared with <30 years of age with no difference found in NAFLD between ethnic groups (Luo, Kamba, Maasai). All body composition and clinical measurements were associated with NAFLD (p < 0.045 for OR). CONCLUSION: Finding lower odds for NAFLD in men was unexpected, as was the lack of differences in NAFLD among the ethnic groups, while higher odds for NAFLD with increasing age and in urban vs. rural populations was expected. Especially the sex-specific results warrant further studies in black African populations on biology of body composition for having NAFLD, and whether this translates into insulin resistance and higher risk of diabetes and consequently cardiovascular disease in black African women.

Public knowledge and expectations about dispatcher assistance in out-of-hospital cardiac arrest.

AIM: To assess the factors associated with the knowledge and expectations among the general public about dispatcher assistance in out-of-hospital cardiac arrest incidents. BACKGROUND: In medical dispatch centres, emergency calls are frequently operated by specially trained nurses as dispatchers. In cardiac arrest incidents, efficient communication between the dispatcher and the caller is vital for prompt recognition and treatment of the cardiac arrest. DESIGN: A cross-sectional observational survey containing six questions and seven demographic items. METHOD: From January-June 2017 we conducted standardized interviews among 500 members of the general public in Norway. In addition to explorative statistical methods, we used multivariate logistic analysis. RESULTS: Most participants expected cardiopulmonary resuscitation instructions, while few expected "help in deciding what to do." More than half regarded the bystanders present to be responsible for the decision to initiate cardiopulmonary resuscitation. Most participants were able to give the correct emergency medical telephone number. The majority knew that the emergency call would not be terminated until the ambulance arrived at the scene. However, only one-third knew that the emergency telephone number operator was a trained nurse. CONCLUSION: The public expect cardiopulmonary resuscitation instructions from the emergency medical dispatcher. However, the majority assume it is the responsibility of the bystanders to make the decision to initiate cardiopulmonary resuscitation or not. Based on these findings, cardiopulmonary resuscitation training initiatives and public campaigns should focus more on the role of the emergency medical dispatcher as the team leader of the first resuscitation team in cardiac arrest incidents.
