The effect of sense of security on job performance of medical staff: the mediating effect of psychological capital.

Objective: To investigate the current situation of sense of security, psychological capital and job performance of medical staff in Guangdong Province, and to explore the mediating role of psychological capital on the relationship between sense of security and job performance of medical staff. Methods: In this study, 969 health care workers were selected from February 2023 to April 2023 from 37 hospitals in Guangdong Province, China, using purposive sampling method. The Sense of Security Scale for Medical Staff (SSS-MS), psychological capital scale (PCS) in Chinese version and the Chinese version of job performance scale (JPS) were used in this study. We use SPSS 26.0 for statistical analysis and Amos 24.0 for structural equation modeling (SEM). The control variables entering SEM were selected by regression analysis. SEM analysis confirmed psychological capital scale's mediating function in the link between work performance scale and Sense of Security. Results: The overall SSS-MS, PCS, and JPS scores were 67.42 ± 16.136, 87.06 ± 15.04, and 77.87 ± 10.50, respectively. The results of Pearson's correlation analysis showed that there was a positive relationship between PCS and JPS (r = 0.722, P < 0.01), SSS-MS and JPS (r = 0.312, P < 0.01), and SSS-MS and PCS (r = 0.424, P < 0.01). PCS demonstrated a fully mediating influence on the link between medical workers' SSS-MS and JPS, according to structural equation modeling. Conclusion: The JPS of medical personnel in Guangdong Province is at a medium level, with much room for improvement. PCS is positively impacted by a sense of security. There is a supportive correlation between PCS, JPS, and SSS-MS. Furthermore, PCS fully mediates the relationship between medical staff members' JPS and their SSS-MS. The Job Diamond-Resource model and Conservation of Resource theory are further validated and supplemented by the findings of this study, which also gives managers a theoretical foundation for enhancing medical staff performance.

Application of machine learning in predicting frailty syndrome in patients with heart failure.

Prevention and diagnosis of frailty syndrome (FS) in patients with heart failure (HF) require innovative systems to help medical personnel tailor and optimize their treatment and care. Traditional methods of diagnosing FS in patients could be more satisfactory. Healthcare personnel in clinical settings use a combination of tests and self-reporting to diagnose patients and those at risk of frailty, which is time-consuming and costly. Modern medicine uses artificial intelligence (AI) to study the physical and psychosocial domains of frailty in cardiac patients with HF. This paper aims to present the potential of using the AI approach, emphasizing machine learning (ML) in predicting frailty in patients with HF. Our team reviewed the literature on ML applications for FS and reviewed frailty measurements applied to modern clinical practice. Our approach analysis resulted in recommendations of ML algorithms for predicting frailty in patients. We also present the exemplary application of ML for FS in patients with HF based on the Tilburg Frailty Indicator (TFI) questionnaire, taking into account psychosocial variables.

Knowledge, Attitudes, and Practices Towards ECC Prevention in Thai Medical Personnel.

OBJECTIVE: This study aimed to identify the knowledge, attitudes, and practices related to the prevention of early childhood caries (ECC) amongst medical personnel in well-baby clinics (WBC). METHODS: Participants were 152 health care professionals, including public health officers, nurses, and physicians, working in WBC in Chonburi Province, Thailand. Participants completed a 6-part online questionnaire asking about demographic data, knowledge and attitudes related to ECC, ECC prevention practices, collaboration, referral systems, and suggestions for improving collaboration between dental and medical personnel in WBC. RESULTS: Whilst most participants had high levels of knowledge about oral care instructions, tooth brushing frequency, and cariogenic foods and beverages, they knew less about recommendations for timing of the first dental visit, fluoride concentration in toothpaste, and the time for exfoliation of primary teeth. There were significant differences in the proportions of correct answers to questions related to the first dental visit and bottle feeding and in total knowledge scores between physicians and other health care professionals. Most participants demonstrated a positive attitude towards ECC prevention. More than 70% of participants always advise parents on oral hygiene and nutrition related to ECC prevention, but only 29% always refer patients to see dental personnel. Attitudes, collaboration, and referral systems were significantly associated with ECC prevention practices, but not knowledge. CONCLUSIONS: This study demonstrates that attitudes, collaboration, and referral systems are key contributors to ECC prevention amongst Thai medical personnel. In addition to training programmes, consistent interprofessional policy and referral systems should be formulated, especially in primary care settings.

9-Month observational Dia-Vacc study of vaccine type influence on SARS-CoV-2 immunity in dialysis and kidney transplant patients.

BACKGROUND: SARS-CoV-2mRNA vaccination related seroconversion rates are reduced in dialysis and kidney transplant patients. METHODS: We evaluated nine months follow up data in our observational Dia-Vacc study exploring specific cellular (interferon-γ release assay) or/and humoral immune responses after 2x SARS-CoV-2mRNA vaccination in 880 participants including healthy medical personnel (125-MP), dialysis patients (595-DP), kidney transplant recipients (111-KTR), and apheresis patients (49-AP) with positive seroconversion (de novo IgA or IgG antibody positivity by ELISA) after eight weeks. FINDINGS: Nine months after first vaccination, receptor binding domain (RBD) antibodies were still positive in 90 % of MP, 86 % of AP, but only 55 %/48 % of DP/KTR, respectively. Seroconversion remained positive in 100 % of AP and 99·2 % of MP, but 86 %/81 % of DP/KTR, respectively. Compared to MP, DP but not KTR or AP were at risk for a strong RBD decline, while KTR kept lowest RBD values over time. By multivariate analysis, BNT162b2mRNA versus 1273-mRNA vaccine type was an independent risk factor for a strong decline of RBD antibodies. Within the DP group, only time on dialysis was another (inverse) risk factor for the DP group. Compared to humoral immunity, T-cell immunity decline was less prominent. INTERPRETATION: While seroconverted KTR reach lowest RBD values over time, DP are at specific risk for a strong decline of RBD antibodies after successful SARS-CoV-2mRNA vaccination, which also depends on the vaccine type being used. Therefore, booster vaccinations for DP should be considered earlier compared to normal population.

The Connotation System and Practice Dimension of Ideological and Political Education in Medical Discipline / 中国医学伦理学

This paper analyzed the value and inevitability of ideological and political education in medical discipline from the perspective of medical discipline, "three-all education" and medical personnel training, and expounded the connotation system and practical dimension of "ideological and political education in medical discipline" in the framework of subject form, object form, mediator form, theory form, practice form and system form.

Risk Factors and Countermeasures of Occupational Exposure of Medical Personnel under COVID-19 Epidemic / 中国医学伦理学

The COVID-19 is a severe respiratory pathogen infection, showing a distinct "hospital cluster" transmission characteristics. This paper illustrated the concept of occupational exposure and COVID-19. Combined with the actual situation of COVID-19, the infection status of medical personnel in this outbreak was analyzed from three aspects: the transmission risk and infection rate of medical personnel, the clinical characteristics and the undiscovered super-spreader. Through the analysis of the present situation, this paper summarized the possible occupational exposure risk factors of medical personnel in COVID-19 from five aspects: biological occupational risk factors, chemical occupational risk factors, physical occupational risk factors, violence factors and psychological factors. From isolating the source of infection and cutting off the transmission route, the "safety supervisor" mechanism is established to avoid the risks of biological, chemical and physical occupational exposure, from providing professional psychological counseling for medical personnel to reduce their psychological stress, and from improving the relevant legal level to reduce the risk of medical personnel’s violent occupational exposure.

Protection of the Right to Life and Health of Medical Staff in Public Health Emergency: Based on the Case of COVID-19 Epidemic / 中国医学伦理学

With the COVID-19 outbreak, many provinces and municipalities have announced the first-level response to public health emergencies. As the backbone of fighting the epidemic, medical staff are faced with many ethical dilemmas, such as the lack of medical protection materials, the high risk of virus infection, discrimination and so on, and their health and life rights and interests have been impacted. Starting with the concept of public health emergencies and the right to life and health, the theory and display basis of the right of life and health were discussed based on the practical guidelines of public health emergencies. Taking the COVID-19 epidemic as an example, this paper proposed measures for ensuring the right to life and health of medical staff in public health emergencies, so as to better cope with the epidemic of COVID-19 and protect the life and health of medical workers.

Midwives' descriptions of avoidable causes of negative perinatal outcomes.

Background: The Perinatal Problem Identification Programme (PPIP) is used to rule out the avoidable and nonavoidable causes of negative maternal and perinatal outcomes through file audits. Perinatal Problem Identification Programme serves as a tool for midwives and obstetricians to pinpoint missed opportunities that could prevent avoidable causes of negative perinatal outcomes. Aim: The study aimed to describe and explore the avoidable causes of negative perinatal outcomes in Bojanala District through the lens of the midwife. Setting: This study was conducted in the two selected facilities in the Bojanala District in the North West Province of South Africa. Methods: The study derived from a larger study that focused on midwives' experiences of obstetric triage in the Bojanala District. A qualitative, exploratory and descriptive research design was used with purposive sample of nine midwives. Participants had over 5 years of clinical midwifery experience and were employed in the Bojanala District. Semi-structured interviews were utilised with data analysed using Colaizzi's descriptive method of data analysis. Results: Three major themes with eight subthemes emerged. Midwives noted space constraints, medicine and medical supply constraints, and constraints in availability of medical equipment. Access to identified constraints would enable prompt and appropriate management. Conclusion: The study highlighted the experience of midwives in accessing needed space, medicines, medical supplies and equipment, potentially impacting negative perinatal outcomes. Contribution: This study provides insight into administratively related avoidable causes of negative perinatal outcomes through the lens of frontline maternity care providers - midwives. Findings should be of particular utility to health service managers working to reduce maternal mortality and morbidity.

[Methodical approach to the construction of the index of doctors' confidence in their activities].

INTRODUCTION: The COVID-19 pandemic has demonstrated the importance of developing a state policy to increase the attractiveness of a doctor's work and counteract professional burnout. The trust of doctors in their work determines the state of human resources in the field of healthcare. The development of an approach to the organization of monitoring the trust of doctors will allow identifying organizations at an early stage in which there is a decrease in the confidence of doctors in their activities. The purpose of the study is to develop and test a methodological approach to calculating the index of trust of doctors. MATERIALS AND METHODS: To construct the index, a list of statements was developed that are applicable for a comprehensive assessment of the doctor's activities. The approbation of the developed approach was carried out as part of a pilot sociological study in which 346 doctors from different regions of Russia took part. The significance of the statements used in the assessment was confirmed by binary probit regression. RESULTS: The analysis made it possible to calculate the index of doctors' trust for the obtained sample, equal to 62,5%. The results of the study can be used to assess the attitude of doctors to their activities both at the regional level and at the level of individual organizations. The Ministry of Health of the Russian Federation can use the results obtained to develop approaches to increasing the attractiveness of the medical profession to increase the public health of Russia.

[HUMAN RESOURCES MANAGEMENT OF A PRIVATE MEDICAL ORGANIZATION].

The article deals with the issues of human resources management of a private medical organization. The author investigates the current state of the staffing of Russian healthcare: the provision of specialists in the healthcare system, professional motivation and prospects for the development of private medicine. In recent years, a system of private medical organizations has been formed in the Russian market of medical services, which provide medical care in parallel with state medical structures. Research in the field of human resource management in healthcare of a theoretical and practical nature shows that the problem of personnel shortage in the field of medicine is urgent and needs to be solved. One of the factors of insufficient staffing of medical organizations is the underinvestment of the healthcare industry over a long period and low preparedness for emergency situations and response to them, which has worsened under the influence of the rapid spread of the coronavirus pandemic. In conclusion, it is concluded that the main task of the effective functioning of a medical organization and the provision of high-quality medical services is the management of human resources. The purpose of this study is to consider the issues of human resources management of a private medical organization.

Mental health survey of medical personnel during pre-job training in a closed-loop management system during the COVID-19 pandemic.

Object: With the aim of enhancing prevention and regional control of epidemics, the mental health status of medical personnel was analyzed before the implementation of closed-loop management during the COVID-19 pandemic in the regional hospital representative. Methods: In accordance with directives from the unified deployment of the national and regional health bureaus, and following the inclusion and exclusion criteria, from September 2021 to November 2022, all medical personnel assigned to a closed-loop working environment by Guangzhou Panyu Central Hospital were enrolled as research subjects through cluster sampling method. Using a cross-sectional survey method, relevant data such as age, gender, professional title, and mental health status were collected. The Patient Health Questionnaire-9 (PHQ-9) scale, the Generalized Anxiety Disorder-7 (GAD-7) scale, and the Insomnia Severity Index (ISI) scale were administered. Logistic regression analysis was used to study the influencing factors of depression, anxiety, and insomnia. Single factor logistic regression analysis was performed first, followed by multiple factor logistic regression analysis. Results: A total of 500 valid responses were received. Depression was reported by a higher proportion of physicians than nurses. Anxiety was reported by higher proportion of men than women and by a higher proportion of physicians than nurses. Medical personnel under the age of 30 years reported fewer symptoms of insomnia than those over the age of 41 years, and medical personnel with intermediate professional titles reported more severe symptoms of insomnia than junior personnel. There was no significant difference between the results of the three questionnaires for medical personnel from other hospital departments or in the different type of closed-loop work environments. Conclusion: During the pandemic, conducting psychological health assessments for medical personnel undergoing pre-job training in closed-loop management was beneficial for the timely detection of psychological problems. Although this study only conducted a cluster sampling survey and lacked comparative analysis on other medical institutions, it still suggested that it was necessary to strengthen timely psychological counseling and intervention for senior male physicians.

The Impact of a Single Supervised Exercise Session in the Third Trimester of Pregnancy on the Physical Activity Levels of Pregnant Women-A Pilot Study.

BACKGROUND: Despite the numerous beneficial effects of physical exercise during pregnancy, the levels of physical activity remain low. The aim of the study is to investigate the impact of a single supervised physical exercise session on the overall physical activity levels of pregnant women. METHODS: During the third trimester, pregnant women attending our outpatient clinic were requested to assess their physical activity levels using the International Physical Activity Questionnaire (IPAQ). Additionally, they were invited to participate in a supervised 30 min mild-moderate-intensity aerobic exercise session (stationary bike ergometer) under the guidance of medical personnel. Subsequently, physical activity levels were reevaluated at the time of delivery. RESULTS: Prior to the intervention, 3 out of 50 (6%) women engaged in mild-moderate physical activity for 150 min per week, while 20 out of 50 (40%) women participated in mild-moderate activity for 15-30 min, twice a week. Following the intervention, these percentages increased to 10 out of 50 (20%) and 31 out of 50 (62%), respectively (p < 0.05). CONCLUSIONS: This pilot study suggests that a single exercise session supervised by medical personnel may significantly improve the low physical activity levels observed in pregnant women.

[On the question of the content of the concept of «professionalism¼ in relation to workers in the field of medicine and healthcare].

The article presents an overview of foreign publications reflecting approaches to the definition of the essence of the concept of «professionalism¼ in relation to representatives of the field of health and medicine. The main personal and professional qualities of the doctor, which are associated with the concept of «professionalism¼ in patients, are noted. It is noted that the formation of professional behavior is influenced not only by the personal qualities of a medical worker, but also by the working environment of the medical organization in which he carries out professional activities. It is concluded that the formation of the professionalism of a medical worker should be carried out with the participation of both the employee himself and the public health system and the system of medical professional education.

[On the need to train medical specialists to work in the conditions of the introduction of remote technologies].

The development of telemedicine and the provision of medical care using remote technologies requires appropriate competencies and skills from medical specialists, the formation of which is an important task of adapting educational systems to modern challenges and responding to requests from both medical staff and patients. Based on the analysis of foreign scientific publications, the paper considers the assessment of the need to train medical workers in remote work with patients and the prospects for the introduction of telemedicine consultations into everyday professional practice. It is concluded that having more knowledge about which aspects of medicine are best combined with telemedicine, it is important to train future medical professionals in the use of these technologies and the provision of these types of medical care. Doctors should not only be trained in the use of telemedicine, but also learn how to do it professionally, safely and on the basis of evidence.

Moxibustion for medical personnel with negative emotion and insomnia during COVID-19 pandemic: A randomized, controlled trial.

Background: We conducted this randomized controlled trial (RCT) to evaluate the effectiveness and safety of moxibustion at Sanyinjiao (SP6) acupoint for treatment of negative mood and sleep quality in healthcare workers during the 2019 coronavirus disease (COVID-19). Methods: A total of 180 participants were divided in a 1:1 ratio into two groups, the treatment group (for moxibustion) and the control group (for no treatment). The treatment group had a 30-minute moxibustion therapy once a day for two weeks, followed by a two-week follow-up. The Hamilton Anxiety Scale (HAMA) was used to assess the degree of the participants' anxiety, and the Patient Health Questionnaire-9 (PHQ-9) was utilized to examine their depressed condition. The Maslach Burnout Inventory-General Survey (MBI-GS) was used to measure the level of burnout among healthcare workers. To determine the severity of insomnia, the Sleep Dysfunction Rating Scale (SDRS) was utilized. At baseline, week 2, and week 4, all scales were evaluated. Results: Compared to the control group, The treatment group improved more significantly in the HAMA at week 2 (MD = -19.01, 95% CI: -21.89 to -16.14; P<0.001) and at week 4 follow-up visits (MD = -8.96, 95% CI: -11.19 to -6.73; P<0.001). A subgroup study of HAMA scores revealed that position and education had significant impact on treatment effectiveness. During the 2-week intervention period, the treatment group showed more significant improvements in depressive symptoms measured by PHQ-9 (13.00±2.41 vs. 15.60±3.65; P<0.001), work burnout symptoms measured by MBI-GS (MD = -11.88, 95% CI, -15.73 to -8.03; P<0.001), and insomnia symptoms measured by SDRS (MD = -2.45, 95% CI, -4.24 to -0.66; P<0.01). There were no significant adverse effects reported. Conclusion: Moxibustion at SP6 may be an effective treatment to improve anxiety, depression, sleep quality, and quality of life for healthcare workers during COVID-19.

Investigation and Analysis on Occupational Exposure Causes and Mental Status of Infectious Diseases in Pre-Hospital Emergency Medical Personnel.

Background: We aimed to probe into the occupational exposure causes and mental status of infectious diseases in pre-hospital emergency medical personnel. Methods: Forty medical personnel with occupational exposure to infectious diseases who participated in pre-hospital emergency work in 120 emergency center of The Fourth Hospital of Hebei Medical University, Shijiazhuang, Hebei, China were selected as respondents from February 2018 to February 2021. The occupational exposure modes, exposure degrees, exposure sites, exposure sources and exposure causes of infectious diseases were summarized, and the mental status of emergency medical personnel after occupational exposure to infectious diseases was analyzed. Results: In the occupational exposure modes of infectious diseases, needle stick injuries were overtly higher than mucosal pollution, hematic and humoral pollution and incised wound by glass (P<0.05). In exposure degrees, slight bleeding was notably higher than excessive bleeding, bleeding and no bleeding (P<0.05). The hand was distinctly higher than the eye in exposure sites (P<0.05). In exposure sources, hepatitis B virus was visibly higher than hepatitis C virus, HIV, syphilis, intravenous drug, hemorrhagic fever and unknown cause (P<0.05). The scores of somatic symptoms, anxiety, depression, fear, interpersonal sensitivity, hostility, compulsion and paranoia in medical personnel were clearly higher than the norm in Chinese adults after occupational exposure to infectious diseases (P<0.05), with no statistical significance in the comparison of psychotic scores. Conclusion: The occupational exposure risk of infectious diseases among pre-hospital emergency medical personnel is high. It is necessary to strengthen pre-job training and education and improve standardized management for protection.
