Influence of Personal and Work Environments on Work-Life Balance Among Emergency Medical Technicians.

Introduction Work-life balance (WLB) is a critical concern for emergency medical technicians (EMTs) because it significantly affects the provision of comprehensive emergency medical services (EMS). This study investigated personal and work-related factors influencing work-to-family negative spillover (WFNS), a key element of WLB, among EMTs. Methods A web-based survey was conducted from July 26 to September 13, 2021, among EMTs in Hokkaido, Japan. The study included 21 facilities that were randomly selected from 42 fire stations. The Japanese version of the Survey Work-Home Interaction-NijmeGen (SWING-J) was used to measure WFNS. Personal background factors, such as age, sex, years of work experience, and education, were surveyed. We also evaluated work environment factors, such as weekly working hours, monthly night shifts, monthly overtime hours, and yearly paid vacation days. Unpaired Student's t-tests, one-way analysis of variance (ANOVA), and multilevel generalized linear model (MGLM) analyses were used to explore the relationships between WFNS and personal and work-related factors. Results A total of 912 respondents were included in our analysis. They were predominantly male (98.2%), with an average EMT work experience of 12.7 years and a mean WFNS score of 1.16 (standard deviation (SD) = 1.67). MGLM analysis, adjusting for covariates, identified years of work experience (ß = -0.129, p = 0.001), monthly overtime hours (ß = 0.184, p < 0.001), and yearly paid vacation days (ß = -0.170, p < 0.001) as independent factors associated with WFNS. Conclusion This study suggested that adjusting WFNS among EMTs could be achieved by reducing overtime hours and fostering an organized approach to paid leave within the work environment.

Tazobactam/ceftolozane and tobramycin combination therapy in extensively drug-resistant Pseudomonas aeruginosa infections in severe burn injury: a case report.

BACKGROUND: Combination therapy with tazobactam/ceftolozane (TAZ/CTLZ) and high-dose aminoglycosides has been reported to be efficacious in extensively drug-resistant (XDR)-Pseudomonas aeruginosa infection. However, there are no reports of efficacy in XDR-P. aeruginosa infection for combination therapy with low-dose aminoglycosides and TAZ/CTLZ. Herein, we describe a rare case of severe burn injury patients with persistent bacteremia due to XDR-P. aeruginosa, which was successfully treated with TAZ/CTLZ and low-dose tobramycin (TOB). CASE PRESENTATION: A 31-year-old man was admitted to the intensive care unit with severe burn injury involving 52% of the total body surface area and a prognostic burn index of 79.5. The patient had recurrent bacterial infections since admission, and blood cultures collected on the 37th day of admission revealed the presence of P. aeruginosa strains that were resistant to all ß-lactams and amikacin (AMK). The results of the antimicrobial synergistic study showed no synergistic effect of low-dose meropenem (MEPM) and AMK combination therapy. The patient had acute renal failure, and it was difficult to increase the dose of MEPM and AMK, respectively. Thus, we initiated TAZ/CTLZ 1.5 g/8 h instead of the AMK and MEPM combination therapy on the 43rd day of hospitalization. Low-dose TAZ/CTLZ was continued because of prolonged renal dysfunction and resulted in a transient clinical improvement. However, the dosage of TAZ/CTLZ could be increased as the renal function improved, but despite an increased TAZ/CTLZ dose, bacteremia persisted, and the blood cultures remained positive. Thus, TOB was added to TAZ/CTLZ at low doses for synergistic effect against Gram-negative bacteria. Blood cultures collected after initiation of combination therapy with TAZ/CTLZ and low-dose TOB were negative on two consecutive follow-up evaluations. Thereafter, although the patient had several episodes of fever and increased inflammatory response, blood cultures consistently tested negative, and all of the wounds healed. On the 93rd day, due to the good healing progress, the patient was transferred to another hospital. CONCLUSIONS: TAZ/CTLZ and low-dose TOB combination therapy showed the potential for synergistic effects. Our present report suggests a novel synergistic treatment strategy for rare cases that are refractory to the treatment of infections, such as XDR-P. aeruginosa infection.

Prehospital emergency care patient satisfaction scale [PECPSS] for care provided by emergency medical teams: Scale development and validation.

The purpose of this study was to develop and validate an emergency medical technician (EMT) care patient satisfaction scale to measure patient satisfaction with prehospital emergency care. To date, patient satisfaction surveys of EMTs have been performed subjectively, e using each facility's questionnaire, without the use of a validated patient satisfaction scale. However, no specific scale has been devised to assess patient satisfaction with EMTs. The study population comprised patients who used an ambulance between November 2020 and May 2021 (N = 202). A survey instrument was administered to participants who provided informed consent. In the process of validating the patient satisfaction scale, an exploratory factor analysis (EFA) of construct validity was performed. The results of the EFA showed a factor structure consisting of five factors: "teamwork", "explanation and communication", "physical treatment and psychological support", "quickness of transport", and "environment in the ambulance". In addition, domain and summary scores showed good internal reliability (Cronbach's range = 0.82-0.94). The patient satisfaction scale developed in this study was designed and validated considering the role of EMTs and patients' needs for prehospital care. This scale may be useful in the development of assessments and interventions to improve patient satisfaction with EMTs.

Influence of work and family environment on burnout among emergency medical technicians.

OBJECTIVE: Burnout among emergency medical technicians is a serious problem affecting delivery of quality emergency medical services. Although the repetitive nature of the job and lower education level requirements for technicians have been reported as risk factors, little is known about the influence of burden of responsibility, degree of supervisor support, and home environment on burnout among emergency medical technicians. This study aimed to test the hypothesis that burden of responsibility, degree of supervisor support, and home environment increase burnout probability. METHODS: A web-based survey was conducted among emergency medical technicians in Hokkaido, Japan from July 26, 2021 to September 13, 2021. A total of 21 facilities were randomly selected from 42 fire stations. Prevalence of burnout was measured using the Maslach Burnout-Human Services Survey Inventory (MBI-HSS). Burden of responsibility was measured using a visual analog scale. Occupational background was also measured. Supervisor support was measured using the Brief Job Stress Questionnaire (BJSQ). Family-work negative spillover was measured using the Japanese version of Survey Work-Home Interaction-NijmeGen (SWING). The cutoff value for burnout syndrome was defined as emotional exhaustion≥27 and/or depersonalization≥10. RESULTS: A total of 700 survey respondents were included, and 27 surveys with missing data were excluded. The suspected burnout frequency was 25.6%. Covariates were adjusted using multilevel logistic regression model analysis. Low supervisor support (odds ratio, 1.421; 95% confidence interval, 1.136-1.406; P<0.001) and high family-work negative spillover (odds ratio, 1.264; 95% confidence interval, 1.285-1.571; P<0.001) were independent factors associated with higher probability of burnout. CONCLUSION: This study indicated that focusing on improvement of supervisor support for emergency medical technicians and creating supportive home environments may assist in reducing burnout frequency.

A suicide attempt by intramuscular injection of pentobarbital sodium into rectus abdominis suggested by computed tomography.

Suicide attempts in humans due to injections of the veterinary drug pentobarbital sodium have been rarely reported. Herein, we present a case of a suicide attempt by intramuscular injection of pentobarbital sodium into the rectus abdominis muscle, which was suggested by computed tomography (CT). A 73-year-old man was brought to the emergency department with GCS 3 (E1V1M1) and an incised wound on the right side of the neck. A bottle of Somnopentyl® (pentobarbital sodium, 64.8 mg/ml), a 20-ml empty syringe with an 18-mm needle, and no. 10 scalpel were present at the scene. At the emergency department, the patient was intubated and was admitted to the intensive care unit. A urine drug screen test by SIGNIFY® ER was positive for benzodiazepines and barbiturates, and continuous veno-venous hemofiltration (CHF) was initiated. The route of drug administration was initially unknown; however, a CT scan revealed swelling of the left rectus abdominis muscle with a wound suggestive of a needle puncture, and the CT analysis suggested 38.16 ml as the maximum dose of pentobarbital sodium. On day 3, the patient's consciousness improved, and he was weaned off CHF and mechanical ventilation. There have been several reports of postmortem CT yielding information on the site of administration of intoxicants, but there have been none for surviving intoxicated patients. This is the first report of the usefulness of CT to identify the site of administration of the causative agent of intoxication while the patient is still alive.

Early favipiravir treatment was associated with early defervescence in non-severe COVID-19 patients.

INTRODUCTION: The antiviral drug favipiravir has been shown to have in vitro antiviral activity against severe-acute-respiratory-syndrome-coronavirus-2 (SARS-CoV-2). In this study, we investigated the clinical benefits and initiation of favipiravir treatment in patients with non-severe coronavirus-disease-2019 (COVID-19). METHODS: This study was a single-center retrospective cohort study. Receiver operating characteristic curves were drawn to calculate the area under the curve, and the optimal cut-off values for the time to initiate favipiravir treatment were calculated to predict defervescence within seven days. Univariate and multivariate Cox regression analyses were performed to identify potential influencing factors of defervescence. This was defined as a body temperature of less than 37 °C for at least 2 days. RESULTS: Data from 41 patients were used for the efficacy assessment. The days from the onset of fever to defervescence showed a positive correlation with the duration from the onset of fever to initiation of favipiravir treatment (r = 0.548, P < 0.001). The optimal cut-off value was the administration of favipiravir on day 4. Patients were assigned to two groups based on the optimal cut-off value from onset to initiation of favipiravir treatment: early treatment group (within 4-days) and late treatment group (more than 4-days). In the multivariate analysis, when adjusted for age, sex, and days from onset to initiation of favipiravir treatment, the significant factors were male sex and days of initiation of the favipiravir treatment. CONCLUSIONS: We recommend that if favipiravir is to be used for treatment, it should be initiated as early as possible.
