- Background: Prehospital emergency care has developed rapidly during the past decades. The care is given in a complex context which makes prehospital care a potential high-risk activity when it comes to patient safety. Patient safety in the prehospital setting has been only sparsely investigated. The aims of the present study were 1) To investigate the incidence of adverse events (AEs) in prehospital care and 2) To investigate the factors contributing to AEs in prehospital care. Methods: We used a retrospective study design where 30 randomly selected prehospital medical records were screened for AEs each month in three prehospital organizations in Sweden during a period of one year. A total of 1080 prehospital medical records were included. The record review was based on the use of 11 screening criteria. Results: The reviewers identified 46 AEs in 46 of 1080 (4.3%) prehospital medical records. Of the 46 AEs, 43 were classified as potential for harm (AE1) (4.0, 95% CI = 2.9-5.4) and three as harm identified (AE2) (0.3, 95% CI = 0.1-0.9). However, among patients with a life-threatening condition (priority 1), the risk of AE was higher (16.5%). The most common factors contributing to AEs were deviations from standard of care and missing, incomplete, or unclear documentation. The most common cause of AEs was the result of action(s) or inaction(s) by the emergency medical service (EMS) crew. Conclusions: There were 4.3 AEs per 100 ambulance missions in Swedish prehospital care. The majority of AEs originated from deviations from standard of care and incomplete documentation. There was an increase in the risk of AE among patients who the EMS team assessed as having a life-threatening condition. Most AEs were possible to avoid. © 2019 The Author(s).

- Background: Patient safety issues in pre-hospital care are poorly investigated. The aim of the planned study is tosurvey patient safety problems in pre-hospital care in Sweden.Methods/Design: The study is a retro-perspective structured medical record review based on the use of 11 screeningcriteria. Two instruments for structured medical record review are used: a trigger tool instrument designed forpre-hospital care and a newly development instrument designed to compare the pre-hospital assessment withthe final hospital assessment. Three different ambulance organisations are participating in the study. Every month,one rater in each organisation randomly collects 30 medical records for review. With guidance from the reviewinstrument, he/she independently reviews the record. Every month, the review team meet for a discussion ofproblematic reviews. The results will be analysed with descriptive statistics and logistic regression.Discussion: The findings will make an important contribution to knowledge about patient safety issues in prehospitalcare.

- BackgroundIn patients who call for the emergency medical service (EMS), there is a knowledge gap with regard to the final assessment after arriving at hospital and its association with field assessment.AimIn a representative population of patients who call for the EMS, to describe a) the final assessment at hospital discharge and b) the association between the assessment in the field and the assessment at hospital discharge.MethodsThirty randomly selected patients reached by a dispatched ambulance each month between 1 Jan and 31 Dec 2016 in one urban, one rural and one mixed ambulance organisation in Sweden took part in the study. The exclusion criteria were age<18years, dead on arrival, transport between health-care facilities and secondary missions. Each patient received a unique code based on the ICD code at hospital discharge and field assessment.ResultsIn all, 1080 patients took part in the study, of which 1076 (99.6%) had a field assessment code. A total of 894 patients (83%) were brought to a hospital and an ICD code (ICD-10-SE) was available in 814 patients (91% of these cases and 76% of all cases included in the study). According to these ICD codes, the most frequent conditions were infection (15%), trauma (15%) and vascular disease (9%). The most frequent body localisation of the condition was the thorax (24%), head (16%) and abdomen (13%). In 118 patients (14% of all ICD codes), the condition according to the ICD code was judged as time critical. Among these cases, field assessment was assessed as potentially appropriate in 75% and potentially inappropriate in 12%.ConclusionAmong patients reached by ambulance in Sweden, 83% were transported to hospital and, among them, 14% had a time-critical condition. In these cases, the majority were assessed in the field as potentially appropriate, but 12% had a potentially inappropriate field assessment. The consequences of these findings need to be further explored.

- This study reports on the poling and characteristics of a melt-spun piezoelectric bicomponent fiber with poly(vinylidene fluoride) (PVDF) as its sheath component and a conductive composite with carbon black (CB) and high density polyethylene (HDPE) as its core component. The influence of poling conditions on the piezoelectric properties of the fibers has been investigated. The poling parameters temperature, time and poling voltage have been varied and the piezoelectric effect of both contact- and corona-poled yarns have been evaluated. The results show that a high piezoelectric effect is achieved when the poling voltage is high as possible and the poling temperature is between 60°C and 120°C. It was also shown that permanent polarization is achieved in a time as short as 2 second in corona-poled fibers. A yarn exposed to a sinusoidal axial tension of 0.07% strain (the corresponding force amplitude was 0.05 N) shows an intrinsic voltage output of 4 V. The mean power from a 25 mm length of yarn is estimated to be 15nW. To demonstrate the fibers sensor properties, they are woven into a textile fabric from which a force sensor is manufactured and used to detect the heartbeat of a human.

- BackgroundSepsis is a severe condition which affects 300–800/100,000 persons each year. There are indications that the prehospital identification of patients with sepsis is difficult. The aim of the study was, among patients with a final hospital diagnosis of sepsis, to compare emergency medical service (EMS) field assessments of patients in whom there was a prehospital suspicion of sepsis with those without this suspicion.MethodsThe study had a retrospective, observational design. The data used in the study were retrieved from the prehospital and hospital medical records of patients with a final hospital diagnosis of sepsis, transported to hospital by the EMS within a region in the south west of Sweden during a period of one year.ResultsAmong patients with a final diagnosis of sepsis (n = 353), the EMS identified the condition in 36% of the cases. These patients were characterised by more abnormal vital signs (a higher respiratory rate and heart rate and more frequent temperature abnormalities) and were more ambitiously assessed (more lung auscultations and more assessments of the degree of consciousness).ConclusionThe EMS was already able to identify 36% of patients with a final diagnosis of sepsis in the prehospital phase. There were minor differences in the prehospital assessment between patients who were identified by the EMS nurse and those who were not.
