The effect of ascending- descending ultrafiltration and sodium profiles on blood pressure in hemodialysis patients: a randomized cross-over study.

BACKGROUND: Considering no previous research into the utilization of ascending/descending ultrafiltration and linear sodium profiles in improving blood pressure among hemodialysis patients, the present study aimed to explore the effect of the A/D-UF along with linear sodium profiles on HD patients with hypotension. METHODS: Applying a crossover design, this clinical trial was fulfilled between December 2022 and June 2023 on 20 patients undergoing HD, randomized into two groups, each one receiving two intervention protocols, viz., (a) an intervention protocol in which the liquid sodium in the dialysis solution was linear and the UF profiling was A/D, and (b) a routine protocol or HD, wherein both liquid sodium and UF in the dialysis solution remained constant. The HD patients' BP was then checked and recorded at six intervals, namely, before HD, one, two, three, and four hours after it, and following its completion, within each session. The data were further statistically analyzed using the IBM SPSS Statistics 20 and the related tests. RESULTS: In total, 20 patients, including 12 men (60%) and 8 women (40%), with the mean age of 58.00 ± 14.54 on HD for an average of 54 months, were recruited in this study. No statistically significant difference was observed in the mean systolic and diastolic BP levels in the group receiving the A/D-UF profile all through the desired hours (p > 0.05), indicating that the patients did not face many changes in these two numbers during HD. Our cross-over clinical trial demonstrated a statistically significant reduction in symptomatic IDH episodes from 55 to 15% with the application of the A/D-UF profile (p < 0.05). CONCLUSION: The study demonstrated that the A/D-UF profile could contribute to the stability of blood pressure levels among HD patients, with no significant fluctuations observed during treatment sessions. TRIAL REGISTRATION: This study was registered in the Iranian Registry of Clinical Trials (no. IRCT20180429039463N5) on 07/01/2023.

The impact of cardiopulmonary rehabilitation in phase II cardiac rehabilitation program on the health-related quality of life of patients undergoing coronary artery bypass graft surgery.

BACKGROUND: Coronary artery bypass surgery is the leading cause of change in the quality of life and pulmonary function of patients. One strategy to enhance lung muscle strength and improve overall quality of life is pulmonary rehabilitation. This study aimed to investigate the impact of incorporating a pulmonary rehabilitation program into phase II cardiac rehabilitation program on the quality of life of patients undergoing coronary artery bypass graft surgery. METHODS: This randomized clinical trial study included 53 patients who underwent coronary artery bypass graft surgery at Imam Reza Hospital in Mashhad between September 2019 and March 2020. The research participants were selected based on specific inclusion criteria and divided into two groups. The control group followed the routine rehabilitation program, whereas the intervention group underwent a pulmonary rehabilitation program for 20-30 min after each session of the cardiac rehabilitation program. Data collection tools included a demographic information questionnaire and the Ferrans and Powers' quality of life index. The data were analyzed using the independent t-test, Mann-Whitney test, paired t-test, Spearman correlation, Wilcoxon test, and SPSS25. RESULTS: The mean quality of life score in the intervention group(20.7±1.8) was significantly higher than that of the control group (18.8±2.3)(P < 0.05). Furthermore, the intervention group exhibited significantly higher mean scores in the physical, psychological-spiritual, and family dimensions than the control group(P < 0.05). CONCLUSION: The study results demonstrate the positive impact of incorporating a pulmonary rehabilitation program into cardiac rehabilitation on the health-related quality of life of patients undergoing coronary artery bypass graft surgery. TRIAL REGISTRATION: IRCT20190707044132N1.

Determining the frequency of burn wound dressing for clinically competent nursing students: establishing standards based on learning curves.

BACKGROUND: The primary objective of clinical practice in nursing education is to achieve mastery of clinical skills through repetitive practice. Therefore, there exists a correlation between the frequency of skill demonstration and clinical competency. This study aimed to address the following question: How many times should a nursing student perform burn wound dressing to attain clinical competency? METHODS: This time series study was conducted on 41 junior nursing students who were selected through a census sampling method at Neyshabur School of Nursing from spring 2015 to summer 2021. The data collection tool was a researcher-made competency evaluation checklist (CEV). The competency score of each student for each skill demonstraion episode was evaluated using the Competency Evaluation Checklist (CEV) and recorded on the learning curve until a plateau was reached. SPSS16 and repeated measures analysis of variance (ANOVA) were used. RESULTS: The mean competency score of burn wound dressing was 67.5 ± 11.0 (out of 100) during the first attempt, which increased to 95.9 ± 4.3 by the ninth attempt. The learning curve for the burn wound dressing skill reached a plateau after five attempts. Additionally, by the fifth attempt of dressing the burn wound, all students could accurately identify the depth, extent, and severity of the wound. CONCLUSIONS: Establishing a standardized frequency for clinical skill performance and ensuring ample practice opportunities can have significant benefits in nursing education systems. These benefits include long-lasting learning, reduced costs, and improved effectiveness. As a result, nurse managers and lecturers should consider the resources available in their educational systems and strive to provide students with adequate opportunities and a supportive environment to practice their skills.

Effects of the COVID-19 pandemic on trauma-related emergency medical service in older people: a retrospective cohort study.

INTRODUCTION: The ever-increasing human life expectancy has currently resulted in a noticeable rise in the world's older population. Addressing the healthcare needs of the older people has become a significant concern for many countries. Moreover, the older people are particularly vulnerable to traumatic events. This study aimed to examine the impact of the COVID-19 pandemic on prehospital care provided by Emergency Medical Services (EMS) for trauma-related cases among the older people in Iran. METHODS: This retrospective cohort study involved analyzing the medical records of 1,111 older people aged above 60 who experienced traumatic injuries and received pre-hospital emergency services from March 2018 to March 2022. In order to collect the data, the checklist made by the researcher was used and data analysis in SPSS16 was done using the Chi-square test and Fisher's exact test. RESULTS: The age group of 60-74 received the highest number of services both before and after the COVID-19 pandemic. The older men experienced more traumatic events compared to women throughout the study period. The majority of the traumatic events occurred between 8 a.m. and 12 p.m. both before and after the COVID-19 pandemic. CONCLUSIONS: The high prevalence rate of geriatric traumas can be primarily attributed to their physical problems and no control over movements caused by old age, as well as unsafe living conditions. To address these issues, it is suggested that facilities be provided to assist with mobility problems. Moreover, constructing suitable pedestrian bridges and regularly checking neighborhoods and surroundings to identify potential risk factors should be prioritized. Once these risk factors are identified, efforts can be made to adjust and eliminate them, thereby minimizing traumatic events and enhancing a safe and friendly environment for the older people.

The trend of change in the role of pre-hospital emergency medical services in Iran's healthcare system: a situational analysis.

INTRODUCTION: Following the significant changes in healthcare systems over the last century, the role of pre-hospital emergency medical services (EMS) has been drawn against numerous challenges. In view of this, the present study aims to reflect on the trend of change in the role of pre-hospital EMS to meet new situations and needs, thereby providing a clear picture of this process. METHODS: Respecting the intricate concept of development and the major changes in Iran's healthcare system, this study was fulfilled using situational analysis (SA), developed by Clarke (2018), in Iran within 2022-2023. For this purpose, the data were collected through semi-structured, in-depth individual interviews with four faculty members, two managers involved in EMS, and six highly skilled EMS personnel in various positions. Moreover, the relevant articles published from 1950 to 2023 were reviewed. The data analysis was then performed via SA in the form of open coding as well as simultaneous analysis through three types of maps, viz., situational, social worlds/arenas, and positional maps, along with constant comparative analysis. RESULTS: Pre-hospital EMS in Iran has thus far had two turning points from 1970 to 2023, wherein academic components, need for equipment and resources, in conjunction with basic needs in the modern society, have been the main propellers. As well, the complexity of care for non-communicable diseases (NCDs), demand for managed care, and technological advancement has gradually resulted in further development in EMS. This trend describes the EMS situation in Iran from 1973 to 2023, as well as the EMS emergence stages, quantitative growth and infrastructure, and clinical education development in 2002-2023, indicating the lack of funding and inadequate scientific infrastructure in proportion to the population receiving such services. CONCLUSION: Considering the trend of change in the approaches adopted by healthcare systems across the world, and given the breakthroughs in nursing and medicine, along the education of professionals during the last thirty years, the descriptions of duties and performance in EMS have moved from primary care and patient transfer to specialized services and outpatient care. In addition, the cultural context specific to Iran, the challenges of women working in EMS centers, the disconnection of service providers, namely, the Iranian Red Crescent Society (IRCS) Relief and Rescue Organization (R&RO), Iran's National Police Force (INPF), and Iran's National Medical Emergency Organization (INMEO), as well as lack of resources and equipment, and the geographical distribution of human resources (HRs) based on population dispersion, are thus among the significant issues facing pre-hospital EMS in this country.

Time indices of pre-hospital EMS missions before and during the COVID-19 pandemic: a cross-sectional study in Iran.

BACKGROUND: The COVID-19 pandemic resulted in many changes in pre-hospital emergency medical services (EMS), including wearing full-body protective suits and well-fitted face masks, which can influence time indices in the course of service delivery. The present study aimed to compare the time indices of pre-hospital EMS missions before and during the COVID-19 pandemic in Iran. METHODS: This descriptive cross-sectional study used census sampling to select 17,860 emergency calls that caused patient transfer to medical facilities from March 2018 to March 2021 and then examined the time indices of pre-hospital EMS missions during the COVID-19 pandemic. The data collection tool was a two-part checklist: patients' individual characteristics and pre-hospital EMS mission time indices. The data were further analyzed using the SPSS16 and independent samples t-test. RESULTS: Out of the patients transferred by the EMS, 11,773 cases (65.9%) were male and 6,087 (34.1%) were female. The most common reason for the emergency calls was accidents (28.0%). Moreover, response time (P < 0.001), on-scene time (P < 0.001), transfer time (P < 0.001), total run time (P < 0.001), and round trip time (P < 0.001) increased significantly during the COVID-19 pandemic. CONCLUSIONS: We concluded that the EMS time indices elevated following the COVID-19 pandemic. Updating pre-hospital information management systems, ambulances and medical equipment, as well as holding training courses for pre-hospital EMS personnel could effectively enhance the time indices of pre-hospital EMS missions.

Investigation of stress, anxiety, and depression levels of Pre-Hospital Emergency Medicine personnel in eastern Iran during the Covid-19 pandemic.

BACKGROUND: Pre-hospital emergency medicine (PHEM) personnel are at risk of developing psychological disorders during the Covid-19 pandemic. This study aimed to investigate depression, anxiety, and stress levels of the Iranian PHEM personnel during the Covid-19 pandemic. METHODS: This descriptive cross-sectional study was performed on 544 PHEM personnel chosen by purposive sampling in North Khorasan, Khorasan-Razavi, South Khorasan, Sistan-Baluchestan, and Kerman provinces in eastern Iran from August to September 2021. Data collection tools included a demographic information questionnaire and the standardized 21-item Depression, Anxiety, and Stress Scale (DASS-21). Data were analyzed in SPSS 16 using one-way analysis of variance and linear regression. RESULTS: The mean scores of depression, anxiety, and stress were 8.7 ± 9.2, 7.0 ± 7.8, and 11.6 ± 9.2, respectively. Depression, stress, and anxiety were more prevalent in the age group of 41-55 years, people with master's and higher degrees, people with a history of underlying diseases, and people with over 10 years of work experience(p < 0.05). Depression and stress also showed a significant relationship with the type of employment. Stress alone was also significantly associated with working less than 35 hours a week and living separately from family(p < 0.05). CONCLUSIONS: PHEM personnel suffer from significant levels of depression, anxiety, and stress during the Covid-19 pandemic. Therefore, in order to improve the mental condition, it is recommended that the work schedule and services provided to these people be designed in such a way that they have more time for rest and communication with their family members. The personnel should also have easier access to the expert team in the fields of counseling and psychiatry.

Trend in the role of licensed practical nurses in health care system: A situational analysis.

BACKGROUND: Over the past hundred years, licensed practical nurses (LPN) have faced several challenges because of the changing situations in health care system. The current study addresses the role changing of LPNs in accordance with the context and new needs. AIMS: This aim of situation analysis is to access what changes have occurred in the role of LPNs in the wake of changes in role of RNs over the past century and What factors and variables have influenced this process? METHODS: This study used a Grounded Theory methodology called Situational Analysis. Data were collected through semistructured and in-depth interviews with 33 nurse. FINDINGS: Researchers identify six themes that focus on how the role of LPNs has been changing and variables have influenced this process. CONCLUSIONS: In Iran, as in other countries of the world, the role of LPNs comes to fore when there are pressing needs and nursing shortage. Iranian policymakers have decided to eliminate LPNs, Although LPNs in other countries are working in community-based settings. Treatment-oriented and self-monitoring structure of the Iranian health care system, new nursing organizations and lack of clear role classification at the caring levels have made the nursing roles ambiguous.
