RESUMO

Objective: Mint and chamomile can effectively reduce the gastric residual volume (GRV). This study aimed to determine the effect of mint extract and chamomile drops on the GRV of trauma patients under mechanical ventilation and nasogastric tube feeding in the intensive care unit. Materials and Methods: This study was a triple-blinded randomized clinical trial with a 2×2 crossover design. Eighty patients were randomly divided to receive mint extract and chamomile drops. Five drops of mint extract and 11 drops of chamomile were gavaged every 6 hr. GRV was measured using a syringe-aspiration method before and 3 hr after each intervention. After a 24-hour washout period, the two groups changed places. Results: In the first phase of the study, before the interventions, the GRV in the mint and chamomile groups was 14.60±7.89 and 13.79±7.12 ml, and after the interventions were 8.13±6.31 and 6.61±4.68 ml, respectively. In the study's second phase, before the interventions, the GRV in the mint and chamomile groups was 10.03±4.93 and 11.46±7.17 ml and after the interventions, GRV was 4.97±4.05 and 6.98±4.60 ml, respectively. The difference in the GRV before and after the intervention was not significantly different between the two groups. Both herbal drugs effectively reduced the GRV (p=0.382). Conclusion: Mint extract and chamomile drops are similarly effective in reducing the GRV in trauma patients under mechanical ventilation and nasogastric tube (NGT) feeding in the intensive care unit.

RESUMO

Background and Aims: Resilience is a process that enables people to control the stressors of their lives. During the COVID-19 crisis, work stress increased among prehospital emergency technicians. So, it was possible to reduce their resilience. This study aimed to investigate the changes in the prehospital emergency technicians' resilience during the pandemic of COVID-19. Methods: A cross-sectional study was conducted at the prehospital emergency department in Qazvin province. For 6 months, 234 emergency technicians participated in this study. Data collection tools included a demographic questionnaire and the emergency medical services resilience scale (EMSRS). Results: The Friedman test indicated no significant difference between the mean scores of EMS employees' resilience during 6 months (p > 0.05). However, the correlation matrix between the scores of EMSRS during 6 months indicated that the resilience scores of EMS employees were positively correlated during the study (p < 0.01). Conclusions: The EMS technicians' resilience was almost constant and moderate during the 6 months of care for patients with COVID-19 and their transfer to the hospital, indicating that the COVID-19 crisis could suppress the emergency medical technicians ability to increase resilience.

RESUMO

Background and Aims: Due to the heavy working shifts, emergency nurses may have to sleep at unusual times of the day, affecting their spouse's sleep. This study proposed to detect the relationship between the woman emergency nurse's sleep quality and the sleep quality of their spouses. Methods: This cross-sectional descriptive-analytical study has lasted for 4 months since June 21, 2020. The study population was all women nurses working at a hospital emergency department. The data was collected by a demographic questionnaire and Pittsburgh sleep quality index (PSQI) for nurses and their spouses. The data were analyzed by descriptive and inferential statistics. Results: The prevalence of sleep quality disorder among female emergency department nurses and their husbands was 82.7% and 80.6%, respectively. The mean sleep quality score of female nurses and their husbands was 8.46 ± 4.43 and 6.50 ± 2.52, respectively. A strong and positive correlation was found between the PSQI score of female nurses and their husbands (p < 0.001). The regression model showed that increasing the body mass index (BMI) of female emergency nurses can decrease their sleep quality. However, increasing the BMI of female emergency nurses' spouses and their work experience in the emergency department can improve their sleep quality. Conclusion: The sleep quality of female emergency department nurses was directly correlated with their husbands' sleep quality. Therefore, the sleep quality of nurses working in the emergency departments and their spouses should be examined periodically.

RESUMO

Background and Aims: Sexual dysfunctions are one of the health problems after natural disasters that are usually less attention. The purpose of this study was to evaluate the effect of the earthquake on men's sexual functions 1 year after the earthquake. Methods: This study was a descriptive-analytical cross-section study that took place a year after the Kermanshah earthquake. The population studied was all men living in the Kermanshah earthquake. Demographic, socioeconomic, psychological, health situations, facilities availability, and environmental situations after the earthquake and International Index of Erectile Function (IIEF) were randomly distributed among men affected by the earthquake. Participants returned the questionnaires through the mail. Based on the IIEF cut-point score, men were divided into two groups: those with sexual dysfunction (Group A) and without sexual dysfunction (Group B). Results: In this study, 225 married men participated. The prevalence of sexual dysfunction in earthquake-affected men was 44.9%. The mean total IIEF scores in the A and B groups were 43.47 ± 7.82 and 62.11 ± 6.39, respectively. There was a significant difference between the total and all subcategories IIEF scores in the two groups (p < 0.001). There was a statistically significant difference between the age (p < 0.001), child numbers (p < 0.017), current live location (p < 0.001), social support after the earthquake (p = 0.033), underlying disease (p < 0.001), availability of sanitary toilets (p < 0.001) and bathrooms (p = 0.002), and total IIEF scores between the two groups (p < 0.001). Conclusions: Approximately half of the earthquake-affected men had sexual dysfunctions. The men's age, child numbers, current live location, social support, underlying disease, and availability of sanitary toilets and bathrooms were influential in the severity of men's sexual dysfunctions after the earthquake. Therefore, crisis managers, policymakers, psychiatrists, and psychologists should pay enough attention to men's sexual dysfunction after earthquakes.

RESUMO

INTRODUCTION: Emergency medical services (EMS) personnel are exposed to stress. Job stress in EMS personnel can reduce their resilience and have adverse effects on their clinical performance and mental health, thus reducing the quality of their work. The present research was performed to determine the effect of psychological hotwash on resilience of emergency medical services personnel. METHODS: This study was a quasiexperimental. Sixty-four EMS personnel were randomly divided into two groups of hotwash and control. The psychological hotwash program was performed in the intervention group for a month based on the protocol; however, the control group continued their usual work and received no intervention. A day and six weeks after the psychological hotwash in the intervention group, the resilience of the EMS personnel was remeasured in both groups. RESULTS: Before the intervention, the participants' mean resilience score was 138.37 ± 7.04 in the intervention group and 137.34 ± 8.48 in the control group. There was a statistically significant difference between the mean scores of resilience in the intervention and control groups a day after the intervention (P=0.003). There was no statistically significant difference between the mean scores of resilience in the intervention and control groups 6 weeks after the intervention (P=0.102). CONCLUSION: The EMS personnel's attendance at psychological hotwash sessions could increase their resilience. Nevertheless, the sessions should not be interrupted because the 6-week interruption of the sessions caused the nonsignificant scores of resilience in the hotwash and control groups. Hence, it is recommended to continue the investigation of the effects of hotwash on resilience, stress reduction, and job burnout reduction in EMS personnel by other researchers in different settings.

RESUMO

BACKGROUND: Moderate-to-severe pain is reported in up to 75% of the patients in the first 48 hours after cardiac surgery. Evidence suggests that distraction is an effective nursing intervention for controlling short-term and transient pain. Distraction can be achieved by various techniques, including progressive muscle relaxation, meditation, and rhythmic breathing (RB). The present research aimed at evaluating the impacts of RB on the severity of sternotomy pain after Coronary Artery Bypass Graft (CABG). METHODS: This randomized, controlled clinical trial was conducted on 60 patients after CABG surgery at the open-heart surgery Intensive Care Unit (ICU) of Kowsar Hospital, affiliated to Semnan University of Medical Sciences in Semnan, Iran. The patients were selected through convenience sampling and randomly assigned to two groups, including (1) intervention or RB and (2) control groups. RB was performed in the intervention group every 12 hours (9 a.m. and 9 p.m.) for three consecutive days after the surgery. The control group received only routine care for pain control (opioid analgesics) with no additional interventions. The severity of pain was measured every day in both groups of patients before and after the interventions using the Visual Analog Scale (VAS). RESULTS: The mean postintervention pain scores were significantly different from the mean preintervention scores in the intervention group (p < 0.05). The changes in the mean pain score in the intervention group were also significantly different from the corresponding changes in the controls (p < 0.05). CONCLUSION: Based on the results, the severity of pain after the intervention was significantly lower in the RB group compared to the control. RB was found to be an effective technique for reducing the patients' pain and is therefore recommended as a post-CABG pain control technique. Iranian Registry of Clinical Trials: this trial is clinically registered with IRCT20120109008665N7, registered 3 September 2018.

RESUMO

BACKGROUND: Sleep disorders occur in the first days after heart surgery. One of the major causes of sleep disorders after coronary artery bypass graft (CABG) is subsequent changes in physiological indicators, such as systolic blood pressure (BP), respiratory rate (RR), saturation of oxygen (O2), and heart rate (RR). This study is aimed to determine the effect of lavender aromatherapy on patients' sleep quality and physiological indicators after CABG. MATERIALS AND METHODS: This study was a randomized clinical trial. Patients after CABG surgery were randomly allocated into the lavender and distilled water groups. Patients in the intervention group inhaled lavender while those in the control group inhaled distilled water for 10 hours. Sleep quality and physiological postoperative data were collected for 3 days. Data were analyzed using repeated measurement test, sample t-test, and Chi-square test. RESULTS: Repeated measurement test showed no significant difference between the lavender and distilled water groups in terms of systolic BP, RR, O2 saturation, HR, and body temperature after matching the effect of time and its interactive effect with the intervention (p > 0.05). This test revealed a significant difference between the lavender and distilled water groups in terms of sleep quality (p < 0.001), such that the sleep quality was higher in the lavender group. CONCLUSION: Lavender aromatherapy can increase patients' sleep quality after CABG surgery. However, it cannot completely treat sleep disorders in such patients. Furthermore, aromatherapy with lavender does not affect the physiological parameters, such as HR, BP, RR, and O2 saturation. HOW TO CITE THIS ARTICLE: Davari H, Ebrahimian A, Rezayei S, Tourdeh M.

RESUMO

OBJECTIVES: Our study sought to determine the effects of valerian on sleep quality, depression, and state anxiety in hemodialysis (HD) patients. METHODS: This randomized, double-blind, placebo-controlled, crossover clinical trial was conducted on 39 patients undergoing HD allocated into a valerian and placebo group. In the first phase of the study, group A (n = 19) received valerian and group B (n = 20) received a placebo one hour before sleep every night for a total of one month. Sleep quality, state anxiety, and depression were assessed in the patients at the beginning and end of the intervention using the Pittsburgh Sleep Quality Index, the Spielberger State-Trait Anxiety Inventory, and Beck Depression Inventory. In the second phase, the two groups' treatment regimen was swapped. After a one-month washout period, the same process was repeated on the crossover groups (i.e., group A received placebo and group B received valerian). RESULTS: In the first phase, the mean sleep quality, depression, and state anxiety scores showed significant reductions in both groups, but the reduction was significantly higher in group A compared to group B (7.6 vs. 3.2, p< 0.001; 6.5 vs. 2.3, p =0.013; 14.6 vs. 7.3, p =0.003, respectively). In the second phase, the mean sleep disorder, depression, and state anxiety scores showed significant reductions in both groups, but the reduction was significantly lower in group A compared to group B (1.4 vs. 4.6, p< 0.001; 1.2 vs. 3.8, p =0.002; 1.5 vs. 6.2, p< 0.001, respectively). CONCLUSIONS: Valerian significantly improved sleep quality, the symptoms of state anxiety, and depression in HD patients.

RESUMO

OBJECTIVE: Tracheal suctioning can cause pain and physiological indicator variations in patients with traumatic brain injury (TBI). The aim of the present study was to compare pain severity and physiological indicator variations during the closed tracheal suction system (CTSS) and open tracheal suction system (OTSS) in patients with TBI. METHODS: This study was a clinical trial. Samples included all ventilated patients with TBI. The patients were randomly divided into the OTSS and CTSS groups. In both groups, the Critical Care Pain Observation Tool (CPOT) and physiological indicators were recorded by three nurses prior to suctioning, the end of suctioning and 5 min after suction completion. Data were analysed using the independent t-test and repeated measurement tests. RESULTS: A total of 112 patients participated in the present study. Before the interventions, the mean value of the Glasgow Coma Scale was 6.45±1.13, blood pressure 128.33±20.54, saturated oxygen in arterial blood (SpO2) 96.74±2.76, respiratory rate (RR) 15.06±3.98, end-tidal CO2 (EtCO2) 36.2±21.98, heart rate 82.18±42.33 and CPOT-based pain 0.43±0.94 in the patients. Independent t-test was used to compare CTSS and OTSS, suggesting significant differences with respect to the mean values of SpO2, RR and EtCO2 immediately after suctioning. This test showed significant differences between the two groups with respect to pain intensity at all three points of measurement. The two groups were also found to be significantly different with respect to RR measured 5 min after suctioning (p<0.05). CONCLUSION: Compared to OTSS, CTSS can cause higher reductions in pain levels during and after suctioning in patients with head traumas and can also cause higher improvements in physiological indicators, such as RR, O2 saturation and EtCO2.

RESUMO

OBJECTIVE: This study aimed to evaluate the effects of acupressure on the symptoms severity, function status and electrodiagnostic findings in patients with Carpal tunnel syndrome (CTS). DESIGN: This double blind, randomized, controlled clinical trial study was conducted on 57 patients with CTS that selected through convenience sampling. The patients were randomly assigned to three groups, including (1) acupressure; (2) placebo acupressure; and (3) control. SETTING: The study was conducted in the medical centers affiliated to Semnan University of Medical Sciences, Iran. INTERVENTION: The intervention groups received acupressure or placebo for one month. The control group received only routine cares (splints and analgesics) with no additional intervention. PRIMARY OUTCOMES: The severity of symptoms and hand function were evaluated by the Boston Carpal Tunnel Syndrome Questionnaire, and electrodiagnostic findings, including Nerve Conduction Velocity (NCV), Distal Sensory Latency (DSL), and Distal Motor Latency (DML) were measured by Electromyography device before and after the intervention. RESULTS: The results showed significant differences in the mean severity of symptoms, hand function, NCV, DSL, and DML before and after the intervention in the acupressure group (P < 0.05). Significant differences were also observed between the means difference in severity of symptoms, hand function, and NCV, DSL, and DML before and after the intervention in the three groups (P < 0.05). CONCLUSION: According to the results, acupressure was effective in reducing the severity of clinical symptoms, improving the hand function, and improving the electrodiagnostic findings. Therefore, the application of acupressure can be recommended for improving clinical symptoms of patients with CTS.

RESUMO

Meeting the spiritual needs of patients with cardiovascular diseases has a significant effect on their speed of recovery and spiritual health, especially in coronary care units (CCUs). The present study was conducted to investigate the effect of spiritual care based on the sound heart model on the spiritual health of patients with acute myocardial infarction (AMI) admitted to the CCU of Chamran Hospital in Isfahan, Iran, in 2016. This clinical trial was conducted on 92 patients with AMI selected by convenience sampling and randomly assigned to the intervention (n = 46) and control (n = 46) groups. The spiritual care program based on the sound heart model was regularly carried out for the intervention group over 3 days at 5-8 PM during their hospital stay, and continued for 1 month at home after discharge from the hospital, and the control group only received routine nursing interventions. The patients completed Paloutzian and Ellison's Spiritual Well-Being Scale at baseline and a month after the intervention. Data were ultimately analyzed using Fisher's exact test, Mann-Whitney's test, the Chi-square test, and the t test. The spiritual care program was able to improve the mean scores of religious health (7.8), existential health (9.3) and the total score of spiritual health (17.1) in the intervention group, while these scores reduced to 0.9, 3.4 and 4.2 in the control group. A significant difference was found between the intervention and control groups in terms of the spiritual health score (P < 0.001). The present findings confirmed the effect of spiritual care based on the sound heart model on promoting spiritual health in patients with AMI. Its application as a holistic care approach is therefore recommended for improving the signs and dimensions of spiritual health in patients with coronary artery disease, especially MI.

RESUMO

INTRODUCTION: This study was proposed to compare the ability and accuracy of modified sequential organ failure assessment (mSOFA), quick SOFA (qSOFA), and qSOFA-65 in predicting the status of nontraumatic patients referred to hospital emergency departments (EDs). MATERIALS AND METHODS: This study was a prospective design that performed on the 746 nontraumatic patients referred to the ED. Each patient data was collected using a demographic questionnaire, mSOFA, qSOFA, and qSOFA-65 scales. Related variables of each scale were recorded based on patients' medical records. Then, the outcome of each patient in the ED was followed up and recorded. The severity and specificity of each scale were estimated by the area under receiver operating characteristic (AUROC) curve at 99% confidence interval (CI). RESULTS: The mean and standard deviation of scores were as follows: mSOFA = 4.40 ± 2.58, qSOFA = 0.50 ± 0.70, and qSOFA-65 = 0.92 ± 0.96. Patients requiring admission to the intensive care unit (ICU) were identified with AUROC curve as follows: mSOFA = 0.882 (99% CI = 0.778-0.865); qSOFA = 0.717 (99% CI = 0.662-0.773); and qSOFA-65 = 0.771 (99% CI = 0.721-0.820), which showed that mSOFA has higher sensitivity and specificity than the other two scales in identifying patients requiring admission to the ICU. CONCLUSION: All three scales were found to be reliable for identifying nontraumatic patients at risk of death and patients requiring admission to the ICU. However, since the time and data required to complete qSOFA and qSOFA-65 are much less than those of mSOFA, it is recommended that qSOFA and especially qSOFA-65 be used in ED to identify critically ill nontraumatic patients.

RESUMO

BACKGROUND: Simulation is one of the strategies which are suggested and used to reduce stress and anxiety in clinical student education. This study aimed to determine the effect of simulation-based training method on psychological health promotion in operating room students in their educational internships. MATERIALS AND METHODS: This study was a clinical trial. Research population was operating room students at Semnan University of Medical Sciences. A demographic questionnaire and the Spielberger's Situational Anxiety Inventory were used as data collection tools. Students were divided into two intervention and control groups randomly. Situational anxiety was measured before the intervention and on the 1st and the last days of the internship. The data from the two groups were compared by using the Mann-Whitney and Friedman statistics at the significant level of 0.05. RESULTS: There was a significant difference between students' situational anxiety scores in the experimental and control groups on the 1st day of internship after education by simulation (P = 0.481). There was a significant difference between the students' anxiety scores in the two groups on the last day of the internship (P = 0.008). CONCLUSION: Simulation of the operating room environment before the internship cannot reduce the operating room students' situational anxiety on the 1st day of internship, but it can reduce their situational anxiety during the internship and significantly reduce it at the end of internship compared to those who are not in the simulated environment.

RESUMO

BACKGROUND: This study aims to evaluate the relationship between chest pain intensity and physiological indicators in patients undergoing coronary artery bypass grafting. METHODS: In this correlational study, chest pain intensity and physiological responses of a total of 126 coronary artery bypass grafting patients (104 males, 22 females; mean age 62.3±8.5 years; range, 45 to 80 years) during respiratory exercise were evaluated in a referral hospital setting between December 2016 and March 2018. On the second day after surgery, pain intensity was measured by a numerical rating scale. Physiological indicators were collected using the Nihon Kohden (MU65) monitoring device. RESULTS: The mean pain intensity score was 7.8±1.9 (range, 1 to 10). There was no significant correlation between the pain intensity and physiological indicators (p>0.05). There was a negative correlation between the pain intensity and age of the patient (r=- 0.183 and p=0.04). Pain intensity was not significantly different between male and female gender (p=0.064). CONCLUSION: Our study results show no significant relationship between the chest pain intensity and physiological responses in patients undergoing coronary artery bypass grafting.

RESUMO

CONTEXT: The capacity completeness are one of the serious problems in the bed's managements of the critical care units in a crisis and disaster situation. Reverse triage can help to hospital surge capacity in this situations. AIMS: The aim of this study was to develop a reverse triage system based on Modified Sequential Organ Failure Assessment (MSOFA) for increasing critical care surge capacity. SETTINGS AND DESIGN: This study was a prospective design that performed on the medical patients in critical care unit. SUBJECTS AND METHODS: The MSOFA score for each patient was calculated in admission time and be continued until discharging time from critical care unit. STATISTICAL ANALYSIS USED: The Cox regression method was used to determine the relative risk values. At last, the patients were divided into three levels for reverse triage. RESULTS: Four hundred and twenty patients were participated in this study. The mean of patients' MSOFA scores in the 1st day of admission in Critical Care was 5.40 ± 3.8. The relative risk of internal patients discharge from critical care was (8.2%). Death relative risks were <25%, higher than 70% and between 25.1% and 69.9% for three color level of green, black, and red, respectively. CONCLUSION: The MSOFA scores can contribute to the design a leveling system for discharging patients from critical care unit. Based on this system, the members of the caring team can predict the final health status of the patient.

RESUMO

INTRODUCTION: Appropriate decision-making is essential in emergency situations; however, little information is available on how emergency decision-makers decide on the emergency status of the patients shifted to the emergency department of the hospital. This study aimed at explaining the factors that influence the emergency specialists' decision-making in case of emergency conditions in patients. METHODS: This study was carried out with a qualitative content analysis approach. The participants were selected based on purposive sampling by the emergency specialists. The data were collected through semistructured interviews and were analyzed using the method proposed by Graneheim and Lundman. RESULTS: The core theme of the study was "efforts to perceive the acute health threats of the patient." This theme was derived from the main classes, including "the identification of the acute threats based on the patient's condition" and "the identification of the acute threats based on peripheral conditions." Conclusions. The conditions governing the decision-making process about patients in the emergency department differ from the conditions in other health-care departments at hospitals. Emergency specialists may have several approaches to decide about the patients' emergency conditions. Therefore, notably, the emergency specialists' working conditions and the others' expectations from these specialists should be considered.

RESUMO

INTRODUCTION: Insulin therapy is the most commonly used treatment for controlling hyperglycemia after coronary artery bypass surgery in both diabetic and nondiabetic patients. Metformin has been indicated for critically ill patients as an alternate for the treatment of hyperglycemia. This study evaluated the effect of metformin and insulin in hyperglycemia treatment after coronary artery bypass surgery in nondiabetic patients. SETTINGS AND DESIGN: This study was a clinical trial comprising nondiabetic patients who had undergone coronary artery bypass surgery. Patients were randomly divided into the insulin group and the metformin group. METHODS: Patients in the insulin group received continuous infusion of insulin while those in the metformin group received 500 mg metformin tablets twice daily. All the patients were followed up for 3 days after stabilization of blood glucose levels. STATISTICAL ANALYSIS: Data were analyzed using Chi-square test and Mann-Whitney U-test. RESULTS: This study included a total of 56 patients. During the study period, the mean blood glucose levels decreased from 225.24 to 112.36 mg/dl (↓112.88 mg/dl) in the insulin group and from 221.80 to 121.92 mg/dl in the metformin group (↓99.88 mg/dl). There was no significant difference in the blood glucose levels of the patients between the two groups at any measurement times (P > 0.05). CONCLUSION: Using 500 mg metformin twice daily is similar to using insulin in nondiabetic patients undergoing coronary artery bypass graft. Therefore, the use of metformin can be considered as a treatment strategy for controlling hyperglycemia in this group of patients.

RESUMO

INTRODUCTION: The number of requests for emergency medical services (EMSs) has increased during the past decade. However, most of the transports are not essential. Therefore, it seems crucial to develop an instrument to help EMS staff accurately identify patients who need pre-hospital care and transportation. The aim of this study was to develop and evaluate the psychometric properties of the Pre-hospital Medical Emergencies Early Warning Scale (Pre-MEWS). MATERIALS AND METHODS: This mixed-method study was conducted in two phases. In the first phase, a qualitative content analysis study was conducted to identify the predictors of medical patients' need for pre-hospital EMS and transportation. In the second phase, the face and the content validity as well as the internal consistency of the scale were evaluated. Finally, the items of the scale were scored and scoring system was presented. RESULTS: The final version of the scale contained 22 items and its total score ranged from 0 to 54. CONCLUSIONS: Pre-MEWS helps EMS staffs properly understand medical patients' conditions in pre-hospital environments and accurately identify their need for EMS and transportation.

RESUMO

In order to improve the ethical climate in health care organizations, it is important to apply a valid measure. This study aimed to investigate the psychometric properties of the Persian version of the Hospital Ethical Climate Survey (HECS) and to assess nurses' perceptions of the ethical climate in teaching hospitals of Iran. A cross-sectional study of randomly selected nurses (n = 187) was conducted in three teaching general hospitals of Tehran, capital of Iran. Olson's Hospital Ethical Climate Survey (HECS), a self-administered questionnaire, was used to assess the nurses' perceptions of the hospital ethical climate. Descriptive statistics, confirmatory factor analysis (CFA), internal consistency, and correlation were used to analyze the data. CFA showed acceptable model fit: an standardized root mean square residual (SRMR) of 0.064, an non-normalized fit index (NNFI) of 0.96, a comparative fit index (CFI) of 0.96, and an root mean square error of approximation (RMSEA) of 0.075. The Cronbach's alpha values were acceptable and ranging from 0.69 to 0.85. The overall Cronbach's alpha coefficient was 0.94. The factor loadings for all ethical climate items were between 0.50 and 0.80, which revealed good structure of the Persian version of the HECS. Survey findings showed that the "managers" subscale had the highest score and the subscale of "doctors" had the lowest score. This study shows that the Persian version of the HECS is a valid and reliable instrument for measuring nurses' perceptions of the ethical climate in hospitals of Iran.

RESUMO

The physiological-social modified early warning score system is a newly developed instrument for the identification of patients at risk. The aim of this study was to investigate the feasibility of using the physiological-social modified early warning score system for the identification of patients that needed prehospital emergency care. This prospective cohort study was conducted with 2157 patients. This instrument was used as a measure to detect critical illness in patients hospitalised in internal wards. Judgment by an emergency medicine specialist was used as a measure of standard. Data were analyzed by using receiver operating characteristics curves and the area under the curve with 95% confidence interval. The mean score of the physiological-social modified early warning score system was 2.71 ± 3.55. Moreover, 97.6% patients with the score ≥ 4 needed prehospital emergency services. The area under receiver operating characteristic curve was 0.738 (95% CI = 0.708-0.767). Emergency medical staffs can use PMEWS ≥ 4 to identify those patients hospitalised in the internal ward as at risk patients. The physiological-social modified early warning score system is suggested to be used for decision-making of emergency staff about internal patients' wards in EMS situations.
