The effects of mindfulness training for emergency department and intermediate care unit nurses.

AIM: The aim of this study was to determine the effects of mindfulness and self-compassion skills on the experienced stress and work satisfaction of emergency department (ED) and intermediate care unit employees. METHODS: All ED and intermediate care unit employees in the study hospital were invited to participate in an introductory lecture about mindfulness, compassion, and the intervention in January 2020. After the lecture, it was possible to enroll in training. This training was postponed due to Covid-19 and started in October 2020. RESULTS: The most important findings of this study are that instructor-led mindfulness training, and the regular use of a smartphone mindfulness application can significantly reduce stress and burnout and promote mindfulness and well-being of ED and intermediate care unit personnel. CONCLUSIONS: This study shows that compact mindfulness training via innovative digital technology has a positive effect in reducing ED and intermediate care unit employees stress and burnout, while improving mindfulness and well-being, and this is consistent with the wider literature. KEY FINDINGS: The regular practice of smartphone-guided mindfulness can reduce stress and burnout, as well as promote mindfulness and well-being among ED and intermediate care unit employees.

Self-warming blanket versus forced-air warming blanket during total knee arthroplasty under spinal anaesthesia: A randomised non-inferiority trial.

BACKGROUND: Arthroplasty patients are at high risk of hypothermia. Pre-warming with forced air has been shown to reduce the incidence of intraoperative hypothermia. There is, however, a lack of evidence that pre-warming with a self-warming (SW) blanket can reduce the incidence of perioperative hypothermia. This study aims to evaluate the effectiveness of an SW blanket and a forced-air warming (FAW) blanket peri-operatively. We hypothesised that the SW blanket is inferior to the FAW blanket. METHODS: In total, 150 patients scheduled for primary unilateral total knee arthroplasty under spinal anaesthesia were randomised to this prospective study. Patients were pre-warmed with SW blanket (SW group) or upper-body FAW blanket (FAW group) set to 38°C for 30 min before spinal anaesthesia induction. Active warming was continued with the allocated blanket in the operating room. If core temperature fell below 36°C, all patients were warmed using the FAW blanket set to 43°C. Core and skin temperatures were measured continuously. The primary outcome was core temperature on admission to the recovery room. RESULTS: Both methods increased mean body temperature during pre-warming. However, intraoperative hypothermia occurred in 61% of patients in the SW group and in 49% in the FAW group. The FAW method set to 43°C could rewarm hypothermic patients. Core temperature did not differ between groups on admission to the recovery room, p = .366 (CI: -0.18-0.06). CONCLUSIONS: Statistically, the SW blanket was non-inferior to the FAW method. Yet, hypothermia was more frequent in the SW group, requiring rescue warming as we strictly held to the NICE guideline. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT03408197.

Zero-heat-flux thermometry over the carotid artery in assessment of core temperature in craniotomy patients.

Zero-heat-flux core temperature measurements on the forehead (ZHF-forehead) show acceptable agreement with invasive core temperature measurements but are not always possible in general anesthesia. However, ZHF measurements over the carotid artery (ZHF-neck) have been shown reliable in cardiac surgery. We investigated these in non-cardiac surgery. In 99 craniotomy patients, we assessed agreement of ZHF-forehead and ZHF-neck (3M™ Bair Hugger™) with esophageal temperatures. We applied Bland-Altman analysis and calculated mean absolute differences (difference index) and proportion of differences within ± 0.5 °C (percentage index) during entire anesthesia and before and after esophageal temperature nadir. In Bland-Altman analysis [mean (limits of agreement)], agreement with esophageal temperature during entire anesthesia was 0.1 (-0.7 to +0.8) °C (ZHF-neck) and 0.0 (-0.8 to +0.8) °C (ZHF-forehead), and, after core temperature nadir, 0.1 (-0.5 to +0.7) °C and 0.1 (-0.6 to +0.8) °C, respectively. In difference index [median (interquartile range)], ZHF-neck and ZHF-forehead performed equally during entire anesthesia [ZHF-neck: 0.2 (0.1-0.3) °C vs ZHF-forehead: 0.2 (0.2-0.4) °C], and after core temperature nadir [0.2 (0.1-0.3) °C vs 0.2 (0.1-0.3) °C, respectively; all p > 0.017 after Bonferroni correction]. In percentage index [median (interquartile range)], both ZHF-neck [100 (92-100) %] and ZHF-forehead [100 (92-100) %] scored almost 100% after esophageal nadir. ZHF-neck measures core temperature as reliably as ZHF-forehead in non-cardiac surgery. ZHF-neck is an alternative to ZHF-forehead if the latter cannot be applied.

Utilization of Prognostic Biomarker Soluble Urokinase Plasminogen Activator Receptor in the Emergency Department: A Tool for Safe and More Efficient Decision-making.

Introduction: Risk stratification in the emergency departments (EDs) is in critical need for new applications due to ED overcrowding and hospitalization of older people. We aimed to evaluate the expediency, efficiency and safety of a prognostic biomarker, soluble urokinase plasminogen activator receptor (suPAR), as a tool for the risk assessment of patients arriving at the ED. Methods: We performed a comparative cross-sectional study in 2 emergency departments (EDs), suPAR measurements being incorporated into routine blood sampling in the intervention ED. The primary outcome was the number of discharges from the ED. The importance of the outcomes was examined by appropriate multi- or bivariate analysis. Results: The absolute and relative number of discharges were similar between the intervention and control groups [121 (55.3%) vs 62 (55.9%)]. No significant differences between the groups were seen in the length of stays in the ED. Patients with low suPAR values were more likely discharged and patients with high suPAR values more likely admitted to hospital. Two admitted patients with low suPAR values could have been discharged safely. Conclusion: The utilization of suPAR did not increase the risk for neither positive nor negative outcomes. Low suPAR values could be potential in discharging more patients safely. Instead of unselected patient populations, the benefits of suPAR measurements in the ED could emerge in the assessment of a more precisely determined and selected group of patients.

Comparison of zero heat flux and double sensor thermometers during spinal anaesthesia: a prospective observational study.

Because of the difficulties involved in the invasive monitoring of conscious patients, core temperature monitoring is frequently neglected during neuraxial anaesthesia. Zero heat flux (ZHF) and double sensor (DS) are non-invasive methods that measure core temperature from the forehead skin. Here, we compare these methods in patients under spinal anaesthesia. Sixty patients scheduled for elective unilateral knee arthroplasty were recruited and divided into two groups. Of these, thirty patients were fitted with bilateral ZHF sensors (ZHF group), and thirty patients were fitted with both a ZHF sensor and a DS sensor (DS group). Temperatures were saved at 5-min intervals from the beginning of prewarming up to one hour postoperatively. Bland-Altman analysis for repeated measurements was performed and a proportion of differences within 0.5 °C was calculated as well as Lin`s concordance correlation coefficient (LCCC). A total of 1261 and 1129 measurement pairs were obtained. The mean difference between ZHF sensors was 0.05 °C with 95% limits of agreement - 0.36 to 0.47 °C, 99% of the readings were within 0.5 °C and LCCC was 0.88. The mean difference between ZHF and DS sensors was 0.33 °C with 95% limits of agreement - 0.55 to 1.21 °C, 66% of readings were within 0.5 °C and LCCC was 0.59. Bilaterally measured ZHF temperatures were almost identical. DS temperatures were mostly lower than ZHF temperatures. The mean difference between ZHF and DS temperatures increased when the core temperature decreased.Trial registration: The study was registered in ClinicalTrials.gov on 13th May 2019, Code NCT03408197.

Pre-hospital suPAR, lactate and CRP measurements for decision-making: a prospective, observational study of patients presenting non-specific complaints.

BACKGROUND: In the pre-hospital setting, non-urgent patients with non-specific chief complaints pose assessment challenges for the emergency medical systems (EMS). Severely ill patients should be identified among these patients, and unnecessary transport to the emergency department (ED) should be avoided. Unnecessary admissions burden EDs, deplete EMS resources and can even be harmful to patients, especially elderly patients. Therefore, tools for facilitating pre-hospital decision-making are needed. They could be based on vital signs or point-of-care laboratory biomarkers. In this study, we examined whether the biomarker soluble urokinase plasminogen activator receptor (suPAR), either alone or combined with C-reactive protein (CRP) and/or lactate, could predict discharge from the ED and act as a pre-hospital support tool for non-conveyance decision-making. METHODS: This was a prospective, observational study of adult patients with normal or near-normal vital signs transported by an EMS to an ED with a code referring to deteriorated general condition. The levels of suPAR, CRP and lactate in the patients' pre-hospital blood samples were analysed. The values of hospitalized patients were compared to those of discharged patients to determine whether these biomarkers could predict direct discharge from the ED. RESULTS: A total of 109 patients (median age: 81 years) were included in the study. Of those, 52% were hospitalized and 48% were discharged from the ED. No statistically significant association was found between suPAR and the ED discharge vs hospitalization outcome (OR: 1.04, 95% CI 0.97-1.13, AUROC: 0.58, 95% CI 0.47-0.69). Adding CRP (AUROC: 0.64, 95% CI 0.54-0.75) or lactate (AUROC: 0.60, 95% CI 0.49-0.71) to the regression models did not improve their diagnostic accuracy. None of the patients with a suPAR value of less than 2 ng/ml were admitted to hospital, while 64% of the patients with a suPAR value of more than 6 ng/ml were hospitalized. CONCLUSION: Pre-hospital suPAR measurements alone or combined with CRP and/or lactate measurements could not predict the ED discharge or hospital admission of 109 non-urgent EMS patients with non-specific chief complaints and normal or near-normal vital signs.

Screening of community-dwelling older patients by the emergency medical services: An observational retrospective registry study.

BACKGROUND: Inadequate nutrition, falls, and cognitive impairment are common problems among acutely ill older people and are associated with complicated and prolonged health problems and mortality. OBJECTIVES: To assess if the emergency medical services can identify patients with nutritional risk, falls risk, and cognitive impairment by using simple screening tools and to assess the prevalence of risks and rate they are reported to the emergency department. SETTING: The study was carried out in Espoo, Finland to patients over the age of 70 requiring non-urgent ambulance transfer to the emergency department. OUTCOME MEASURES: A set of validated electronic screening tools was used to identify patients at nutritional risk, risk of falling and having cognitive impairment. MAIN RESULTS: A total of 488 (8%) out of 5792 patients were screened. Of the patients 60%, (n = 292) had at least one risk: 17% (n = 81) had nutritional risk, 43% (n = 209) falls risk, and 28% (n = 137) cognitive impairment. Twenty-two (5%) were screened positive in all three categories. The observed risk was reported to the emergency department staff in 59% (n = 173) of the patients. CONCLUSION: The emergency medical services can be used in preventive health care to identify patients having nutritional risk, falls risk, or cognitive impairment.

Thermal suit connected to a forced-air warming unit for preventing intraoperative hypothermia: A randomised controlled trial.

BACKGROUND: Inadvertent intraoperative hypothermia is a common occurrence in surgical patients. A thermal suit is an option for passive insulation. However, active warming is known to be more effective. Therefore, we hypothesised that a forced-air warming (FAW) unit connected to the thermal suit is superior to a commercial FAW blanket and a warming mattress in breast cancer surgery. METHODS: Forty patients were randomised to this prospective, clinical trial to wear either the thermal suit or conventional hospital clothes under general anaesthesia. The Thermal suit group had a FAW unit set to 38°C and connected to the legs of the suit. The Hospital clothes group had a lower body blanket set to 38°C and a warming mattress set to 37°C. Core temperature was measured with zero-heat-flux sensor. The primary outcome was core temperature on admission to the recovery room. RESULTS: There was no difference in mean core temperatures at anaesthetic induction (P = .4) or on admission to the recovery room (P = .07). One patient in the Thermal suit group (5%) vs six patients in the Hospital clothes group (32%) suffered from intraoperative hypothermia (P = .04, 95% CI 1.9%-49%). Mean skin temperatures (MSTs) were higher in the Thermal suit group during anaesthesia. No burns or skin irritations were reported. Two patients in the Thermal suit group sweated. CONCLUSIONS: A thermal suit connected to a FAW unit was not superior to a commercial FAW blanket, although the incidence of intraoperative hypothermia was lower in patients treated with a thermal suit.

"Hand hygiene perception and self-reported hand hygiene compliance among emergency medical service providers: a Danish survey".

BACKGROUND: Hand hygiene (HH), a cornerstone in infection prevention and control, lacks quality in emergency medical services (EMS). HH improvement includes both individual and institutional aspects, but little is known about EMS providers' HH perception and motivations related to HH quality. Therefore, we aimed to investigate the HH perception and assess potential factors related to self-reported HH compliance among the EMS cohort. METHODS: A cross-sectional, self-administered questionnaire consisting of 24 items (developed from the WHOs Perception Survey for Health-Care Workers) provided information on demographics, HH perceptions and self-reported HH compliance among EMS providers from Denmark. RESULTS: Overall, 457 questionnaires were answered (response rate 52%). Most respondents were advanced-care providers, males, had > 5 years of experience, and had received HH training < 3 years ago. HH was perceived a daily routine, and the majority rated their HH compliance rate ≥ 80%. Both infection severity and the preventive effect of HH were acknowledged. HH quality was perceived important to colleagues and patients, but not as much to managers. Access to supplies, simple instructions and having or being "a good example" were perceived most effective to improve HH compliance. Self-reported HH compliance was associated with years of experience and perceptions of HCAI's impact on patient outcome, HH's preventive effect, organizational priority, HH's importance to colleagues and patients, and the effort HH requires (p ≤ 0.05). CONCLUSION: Danish EMS providers acknowledged the impact of infections and the preventive effect of HH, and perceived access to HH supplies at the point of care, having or being "a good example" and simple instructions effective to improve HH compliance. Moreover, several behavioral-, normative- and control beliefs were associated with self-reported HH compliance, and thus future improvement strategies should be multimodal.

The focus of temperature monitoring with zero-heat-flux technology (3M Bair-Hugger): a clinical study with patients undergoing craniotomy.

In the noninvasive zero-heat-flux (ZHF) method, deep body temperature is brought to the skin surface when an insulated temperature probe with servo-controlled heating on the skin creates a region of ZHF from the core to the skin. The sensor of the commercial Bair-Hugger ZHF device is placed on the forehead. According to the manufacturer, the sensor reaches a depth of 1-2 cm below the skin. In this observational study, the anatomical focus of the Bair-Hugger ZHF sensor was assessed in pre- and postoperative CT or MRI images of 29 patients undergoing elective craniotomy. Assuming the 2-cm depth from the forehead skin surface, the temperature measurement point preoperatively reached the brain cortex in all except one patient. Assuming the 1-cm depth, the preoperative temperature measurement point did not reach the brain parenchyma in any of the patients and was at the cortical surface in two patients. Corresponding results were obtained postoperatively, although either sub-arachnoid fluid or air was observed in all CT/MRI images. Craniotomy did not have a detectable effect on the course of the ZHF temperatures. In Bland-Altman analysis, the agreement of ZHF temperature with the nasopharyngeal temperature was 0.11 (95% confidence interval - 0.54 to 0.75) °C and with the bladder temperature - 0.14 (- 0.81 to 0.52) °C. As conclusions, within the reported range of the Bair-Hugger ZHF measurement depth, the anatomical focus of the sensor cannot be determined. Craniotomy did not have a detectable effect on the course of the ZHF temperatures that showed good agreement with the nasopharyngeal and bladder temperatures.

Novel Zero-Heat-Flux Deep Body Temperature Measurement in Lower Extremity Vascular and Cardiac Surgery.

OBJECTIVE: The aim of this study was to compare deep body temperature obtained using a novel noninvasive continuous zero-heat-flux temperature measurement system with core temperatures obtained using conventional methods. DESIGN: A prospective, observational study. SETTING: Operating room of a university hospital. PARTICIPANTS: The study comprised 15 patients undergoing vascular surgery of the lower extremities and 15 patients undergoing cardiac surgery with cardiopulmonary bypass. INTERVENTIONS: Zero-heat-flux thermometry on the forehead and standard core temperature measurements. MEASUREMENTS AND MAIN RESULTS: Body temperature was measured using a new thermometry system (SpotOn; 3M, St. Paul, MN) on the forehead and with conventional methods in the esophagus during vascular surgery (n = 15), and in the nasopharynx and pulmonary artery during cardiac surgery (n = 15). The agreement between SpotOn and the conventional methods was assessed using the Bland-Altman random-effects approach for repeated measures. The mean difference between SpotOn and the esophageal temperature during vascular surgery was+0.08°C (95% limit of agreement -0.25 to+0.40°C). During cardiac surgery, during off CPB, the mean difference between SpotOn and the pulmonary arterial temperature was -0.05°C (95% limits of agreement -0.56 to+0.47°C). Throughout cardiac surgery (on and off CPB), the mean difference between SpotOn and the nasopharyngeal temperature was -0.12°C (95% limits of agreement -0.94 to+0.71°C). Poor agreement between the SpotOn and nasopharyngeal temperatures was detected in hypothermia below approximately 32°C. CONCLUSIONS: According to this preliminary study, the deep body temperature measured using the zero-heat-flux system was in good agreement with standard core temperatures during lower extremity vascular and cardiac surgery. However, agreement was questionable during hypothermia below 32°C.

[Towards effective resuscitation training]. / Kohti tehokasta elvytyskoulutusta.

The central aim of Current Care Guidelines for resuscitation is to guarantee effective resuscitation for all cardiac arrest patients as carried out by both laymen and professionals. Basic health care training does not guarantee sufficient competence. In spite of simplification of the resuscitation algorithm, problems appear at all stages of resuscitation. Unused skills will be forgotten without the person self recognizing it. Every health care professional should at least once a year attend the continuing education arranged by persons in charge of resuscitation. New technology will facilitate the reception of feedback from both training sessions and actual resuscitation situations.

Assessment of CPR-D skills of nursing students in two institutions: reality versus recommendations in the guidelines.

Significant differences in basic life support skills including cardiopulmonary resuscitation and defibrillation (CPR-D) were detected when nurses working in one Finnish and one Swedish hospital were tested using an Objective Structured Clinical Examination (OSCE). The purpose of this study was to use OSCE test in assessing guideline based CPR-D skills of newly qualified nurses. The CPR-D skills of newly qualified registered nurses studying in Halmstad University (n = 30), Sweden, Helsinki Metropolia University of Applied Sciences (n = 30), and Finland were assessed using an OSCE which was built up with a case of cardiac arrest with ventricular fibrillation as the initial rhythm. The Angoff average, 32.47, was calculated as cutoff point to pass the test. Forty-seven percent of the students in the Swedish group (mean score 32.47/49, range 26-39, SD 3.76) and 13% of the students in the Finnish group (mean score 23.80/49, range 13-35, SD 4.32) passed the OSCE (P<0.0001), the cutoff point being 32.47. Performance grade for the Swedish group was 2.9/5.0 and for the Finnish group 2.1/5.0 (P<0.0001). Good nontechnical skills correlated with high grading of the clinical skills. In conclusion, CPR-D skills of the newly qualified nurses in both the institutes were clearly under par and were not adequate according to the resuscitation guidelines. Current style of teaching is unlikely to result in students being able to perform adequate CPR-D. Standardized testing would help in controlling the quality of learning.

Methods of assessing cardiopulmonary resuscitation skills: a systematic review.

Valid and reliable instruments are needed for assessment and comparison of training outcomes after various methods of cardiopulmonary resuscitation training. Trials were retrieved by searching MEDLINE (1990-February 2005) and using the reference lists of original communications and reviews. Studies were considered relevant if they included an intervention, a study population of life support providers randomized and divided into groups and an evaluation or assessment of the performance. The studies were analyzed and scored to assess their validity. Twenty-five studies fulfilled the criteria. Nineteen of them assessed cardiopulmonary resuscitation skills, four cardiopulmonary resuscitation and defibrillation and two assessed defibrillation only. The mean number of participants was 107 (range 36-495). A wide variety of assessment methods were used in the studies with methodological shortcomings. Most studies in this review compared participants with each other, not against a standard or a defined passing level. Qualified studies with well defined study populations, standardized study settings and explicit, comparable outcomes would be needed to assess the quality of cardiopulmonary resuscitation and defibrillation performance.

Medical and nursing students' attitudes toward cardiopulmonary resuscitation and current practice guidelines.

PURPOSE OF THE STUDY: Every member of a healthcare organisation should be able to perform cardiopulmonary resuscitation and defibrillation (CPR-D). The purpose of this cohort study was to examine medical and nursing student's beliefs and attitudes toward CPR-D and current practice guidelines. MATERIALS AND METHODS: A pilot questionnaire concerning beliefs and attitudes toward CPR-D was distributed to 120 fourth year medical students. After statistical analyses (Cronbach's alpha), the questionnaire was modified to increase its reliability. The second version was distributed via e-mail to 100 final sixth year medical students and to 120 final fourth year nursing students. The students had 2 weeks to answer the questionnaire. A reminder was sent via e-mail after 1 week. RESULTS: The questionnaire was answered by 71 of 120 fourth year students (59.1%), 56 of 100 (56.0%) sixth year medical students and 76 of 120 (63.3%) nursing students. Seventy percent of the fourth year, 85.8% of the final (sixth) year medical students and 70.0% of the final (fourth) year nursing students felt confident about their ability to perform basic life support (p<0.01) and 24.0% of the fourth year, 84.0% of the final year medical students and 22.7% of the nursing students about defibrillation (p<0.001). The perceived ability to defibrillate correlated significantly with a positive attitude toward nurse-performed defibrillation (p<0.01) and negatively with fear of damaging the patient's heart by defibrillation (p<0.01). Negative attitude toward defibrillation correlated with perceived organisational attitudes toward practise guidelines (p<0.01). CONCLUSIONS: Medical students' attitudes mature as hoped for, but the nursing students need encouragement. More information is needed to diminish anxiety concerning defibrillation. Negative beliefs and attitudes toward defibrillation affect the students' attitudes toward practice guidelines.
