Analysis of The Impact of The Healthcare Roundtable Model on the Major Disease Perceptions and Competencies of Cardiovascular Medicine Nursing Staff

Objective: To analyze the impact of the healthcare roundtable model on the major disease perceptions and competencies of cardiovascular nursing staff. Methods: Forty female nursing staff working in the hospital from April to June 2023 were selected and were randomly divided into a control group and an observation group, with 20 in each group. For 60 days, the control group used the conventional learning and communication model and the observation group used the medical and nursing roundtable model. The cognitive scores of cardiovascular disease-related knowledge, competency scores, and satisfaction with the learning and communication model before and after the implementation of the model in both groups were compared. Results: After the implementation, the cognitive scores related to cardiovascular disease-related knowledge, competency scores, and satisfaction with the learning and communication model in the observation group were significantly higher than those in the control group (P < 0.05). Conclusion: The healthcare roundtable model improved the knowledge and competence of cardiovascular internal medicine nursing staff in major diseases, and it is worth popularizing.

Prevalence and related factors of post-traumatic stress disorder among medical staff members exposed to H7N9 patients

Objective: This study aimed to evaluate the prevalence and related factors of post-traumatic stress disorder (PTSD) symptoms among doctors and nurses who were exposed to H7N9 patients during the H7N9 influenza epidemic.To provide scientific basis for promoting the physical and psychological health of these staff members.Method: The 102 medical staff workers who were exposed to H7N9 patients were recruited through convenient sampling between January 2015 and May 2016.We used a self-reported questionnaire,the PTSD Checklist-Civilian Version (PCL-C),to evaluate the PTSD symptoms among doctors and nurses from an intensive care unit (n =61),a respiratory department (n =20),and an emergency department (n =21).We then analyzed the related factors.Results: Around 20.59% of the tested doctors and nurses showed PTSD symptoms.The sample had a mean PCL-C score of 30.00 ± 9.95.The differences in the scores of doctors and nurses with different genders,ages,professional titles,contact frequencies,trainings,and experiences were statistically significant (P < 0.05,P < 0.01).Moreover,t-tests and one-way analysis of variance showed that nurses received higher scores than doctors,female participants received higher scores than male participants,and the participants with low professional title and high contact frequency,aged between 20 years and 30 years,with less than five years of work experience,having not received related training and with no related experience obtained higher PCL-C scores than the others (P < 0.05,P < 0.01).Conclusion: The PTSD level of doctors and nurses after their exposure to H7N9 patients was high,which warrant further research.Health and medical institutions should pay attention to the physical and psychological health of these staff members.

Stress and sleep:a survey based on wearable sleep trackers among medical and nursing staff in Wuhan during the COVID-19 pandemic

Backgroud COVID-19 pandemic has significantly affected the sleep health of local medical and nursing staff.Aim We used wearable pulse oximeters to monitor and screen the medical and nursing staff working in hospitals designated for COVID-19 in the Wuhan area.This study aimed to establish a reliable basis to provide sleep intervention for the medical and nursing staff.Methods Thirty medical and nursing staff members with symptoms of insomnia were instructed to wear medical ring-shaped pulse oximeters to monitor their sleep overnight.We also used the Insomnia Severity Index(ISI)and the Chinese version of the Self-Reporting Questionnaire(SRQ-20)to evaluate the severity of insomnia and mental health status,respectively,for each participant.Results Among the 30 participants,only 26 completed the screening.Ten cases(38.5%)demonstrated moderate to severe sleep apnoea-hypopnea syndrome(SAHS)when using an oxygen desaturation index^15 times/hour as the cut-off value.Participants with comorbid moderate to severe SAHS had significantly higher ISI and SRQ scores(p values 0.034 and 0.016,respectively)than those in the insomnia group.Correlation analysis revealed that ISI was positively correlated with total sleep time(TST)(r=0.435,p=0.026),and negatively correlated with deep sleep(r=-0.495,p=0.010);furthermore,patient SRQ scores were positively correlated with TST,sleep efficiency(SE)and REM(rapid eyes movement)sleep%(r=0.454 and 0.389,0.512;p=0.020,0.050 and 0.008,respectively).Stepwise logistic regression indicated that SRQ-20 and sex were risk factors for insomnia with comorbid SAHS,and their OR values were 1.516 and 11.56(95%Cl 1.053 to 2.180 and 1.037 to 128.9),respectively.Conclusion Medical and nursing staff with insomnia showed clear signs of comorbid sleep apnoea attributable to stress.The wearable pulse oximeters accurately monitored the participants'breathing when asleep.

Are mindfulness and self-efficacy related to presenteeism among primary medical staff: A cross-sectional study

Objectives: In ensuring public welfare with primary medical and health services,the primary medical staff faces new tasks.Increasing workload,and therefore degrees of stress and burnout,can influence job satisfaction and lead to presenteeism,which is defined as the appearance to be on the job but not actually working.The purpose of this study is to investigate the current worling situation and the relationship between presenteeism and mindfulness of primary medical staff and determine the mediating effect of self-efficacy on this relationship.Method: A cross-sectional survey was performed with 580 primary medical staff from 9 hospitals in Shaanxi province,northwest China.Presenteeism,mindfulness,and self-efficacy were measured by using a general information questionnaire,the Five-Facet Mindfulness Questionnaire,the General Self-Efficacy Scale,and the Stanford Presenteeism Scale.Mediating effect was analyzed by a series of hierarchical multiple regressions.Results: A high level of presenteeism was found among 47.4% of the study participants.Presenteeism was negatively correlated with mindfulness(r--0.409,P < 0.001) and self-efficacy(r--0.678,P < 0.001).A positive correlation was found between mindfulness and self-efficacy(r-0.584,P< 0.001).When controlling for self-efficacy (β =-0.018,P> 0.05),the association was insignificant between presenteeism and mindfulness.Conclusion: The results identified the effect of mindfulness on presenteeism of primary medical staff is realized through self-efficacy,which also suggested to enhance self-efficacy on center location when developing management strategies for mental health education or training among primary medical staff.

Healthcare staff well-being and use of support services during COVID-19:a UK perspective

Background The COVID-19 pandemic has drastically increased demands on healthcare workers(HCWs)leaving them vulnerable to acute psychological distress,burnout and post-traumatic stress.In response,supportive services in a central London hospital mobilised mental health support specifically for HCWs.Aims This rapid evaluation assessed HCW psychological welfare during the acute phase of the COVID-19 pandemic and their use of supportive services made available.Methods During the acute phase of COVID-19(April to May 2020)all staff working for the hospital were invited to complete an online survey assessing well-being(self-rated health,moral distress exposure,symptoms of burnout and psychological distress)and use of available supportive services(awareness of,use and perceived helpfulness).Associations among personal characteristics and psychological well-being were explored using correlations and linear regression.Results A total of 1127 staff participated in the rapid evaluation.On average,psychological distress was high(mean(SD):22(7.57))regardless of role,with 84%of this sample scoring above the general population mean(14.5).Nearly half of the sample reported feeling emotionally drained and a profile emerged displaying higher levels of psychological distress and burnout in those who were younger and exposed to morally distressing situations,with this group also exhibiting greater support service use.Greater levels of burnout were associated with increased psychological distress when controlling for personal factors.During this acute phase of the pandemic,majority of staff used at least one service and rated it as helpful.Conclusion HCWs experienced high levels of psychological distress requiring continued support as the COVID-19 pandemic evolved.Although HCWs were aware of supportive services,uptake varied.In order to mitigate the risk of burnout and post-traumatic stress,long-term,effective strategies that facilitate staff accessing support are urgently required.

An investigation into the occupational protection status of clinical nursing staff exposed to anti-tumor drugs

Objective:To investigate the occupational protection status of clinical nursing staff vocationally exposed to anti-tumor drugs.Methods:A self-designed questionnaire was used to survey 180 clinical nursing staff vocationally exposed to anti-tumor drugs.Results:Recognition of the need for protection and dependent occupational protection behaviors were very poor in clinical nursing staff vocationally exposed to anti-tumor drugs.The management of the occupational protection of clinical nursing staff vocationally exposed to anti-tumor drugs was also seriously underdeveloped.Conclusion:There is deficiency in the understanding and related protection practices of clinical nursing staff vocationally exposed to anti-tumor drugs in our hospital.The protection measures currently employed in medical practice are inadequate in virtually every aspect considered.It is recommended that all clinical nursing staff should receive full occupational protection training in these matters.The training must raise nursing staff's awareness of the need for occupational protection and standardize their occupational protection behaviors to conform to "best practice" models.These "best practice" models should be quickly established and all staff made cognizant of them forthwith.In addition,where occupational protection systems are already in place,they should be improved to come into line with the new "best practice" models instigated.

Study on the Relationship between Nursing Staffing and Nosocomial Infection in Very Low Birth Weight Infants

Background: At present, there is no domestic research on the relationship between nurse staffing and hospital infection in very low birth weight infants. In this paper, we will explore the relationship between nurses of very low birth weight (VLBW) infants in neonatal intensive care unit (NICU) and nosocomial infections. Methods: The clinical data of 280 very low birth weight infants born in our hospital from January 2010 to January 2020 were collected, and the chi-square test and multiple logistic regression analysis were used to study the nursing staff of each very low birth weight infant who was admitted to the NICU The relationship between the number of infections and hospital infections. Results: On average, each nurse needs to care for 4.3 very low birth weight infants (lowest to highest: 2.50 - 8.42). In the univariate analysis, the higher the incidence of urinary tract infection (P < 0.05), the multivariate logistic regression analysis of neonatal nosocomial infection showed that nurse staffing was significantly related to the incidence of urinary tract infection (OR = 1.78;95% confidence interval, 1.17 - 2.35, P < 0.05). However, there was no significant correlation between nurse staffing and bloodstream infection (OR = 0.91;95% confidence interval, 0.74 - 1.06, P > 0.05) or Ventilator associated pneumonia (VAP) infection (OR = 1.17;95% confidence interval, 0.94 - 1.47, P > 0.05). Conclusion: Our research shows that in the neonatal intensive care unit, the reasonable deployment of nursing staff is an important factor in preventing urinary tract infections in very low birth weight infants. It is important for improving the survival rate of very low birth weight infants and reducing the occurrence of sequelae.

Knowledge of Nursing Staff on Postoperative Pain: The Case of the Laquintinie Hospital in Douala, Cameroon

Background and objective: Pain is a major concern in the surgical environment, but its management remains insufficient due to several factors related to the nursing staff, the organization of the structure or the patient himself. The objective of this study was to assess the knowledge of the nursing staff on postoperative pain at the Laquintinie Hospital in Douala. Methodology: This was a cross-sectional study carried out at the Laquintinie Hospital in Douala from September to December 2018. Participants were consecutively selected among members of nursing staff in charge of operated patients in the visceral surgery, trauma surgery, surgical reanimation, gynaecology and obstetrics services. Socio-professional data and data related to knowledge of postoperative pain were collected from this personnel using a pre-tested semi-structured questionnaire. Results: With regard to knowledge of postoperative pain, the proportion of correct answers to the knowledge questions was 61.4%. This proportion varied significantly with the specific training received on pain and the specialization of the nursing staff (p < 0.001). Conclusion: The results of the study reveal knowledge in this population that deserves to be improved with a view to better management of patients undergoing surgery.

Intraoperative complication rates in cataract surgery performed by resident trainees and staff surgeons in a tertiary eyecare center in Hungary

AIM: To compare the incidence of intraoperative complications during primary phacoemulsification(phaco) surgery between resident surgeons(residents) and staff surgeons(specialists) and to objectively determine the difficulty of stages in phaco surgery. METHODS: This retrospective study included cases of phaco cataract surgery performed between January and December 2019. There were no exclusion criteria. For each patient, demographics, clinical history, case complexity, type of surgeon, and operative details were reviewed. Primary outcomes included intraoperative complication rates and the objective measure of difficulty in the steps of the surgery performed by residents and specialists.RESULTS: A total of 3272 cases were included;7.4%(n=241) of cases were performed by residents. The overall complication rate was 5.4%(n=177). The intraoperative complication rate was significantly higher(P<0.001) in residents(n=33, 13.7%) than in specialists(n=144, 4.8%). The most frequent complications were posterior capsule tear(n=85, 2.6%), anterior capsule tear(n=50, 1.53%), zonular fiber loss(n=45, 1.38%), and dropped nucleus(n=15, 0.46%). Objectively, the most difficult steps during surgery were phaco in 66(60.0%), capsulorhexis in 21(19.1%), irrigation/aspiration in 13(11.8%), hydrodissection in 9(8.2%), and intraocular lens(IOL) implantation in 1(0.9%) case. CONCLUSION: Intraoperative complication rates are higher in residents than in specialists. The order of objective difficulty in phaco surgery steps is in line with the subjective findings of other surveys, revealing that the most challenging parts of phaco surgery are phaco and capsulorhexis.

Review of possible psychological impacts of COVID-19 on frontline medical staff and reduction strategies

Like soldiers,frontline medical staff provide a first line of defense and have played a critical role in responses to the outbreak of coronavirus disease-2019 in December 2019.It is important to acknowledge the considerable pressure placed on frontline medical staff in the face of a new type of coronavirus that is highly infectious and for which no specific treatment is available.Here,we review the various kinds of psychological problems afflicting frontline medical staff who are combatting the severe acute respiratory syndrome epidemic.These include anxiety,insomnia,depression,interpersonal difficulties,and post-traumatic stress disorder syndrome.We further present a summary of countermeasures for alleviating these problems based on our findings.These countermeasures include ensuring the provision of adequate protective gear for frontline medical staff,developing timely and clear guidelines,strengthening social support,and providing clear criteria and additional training,focusing on the choice of frontline medical staff.An understanding of the psychological impacts of an epidemic situation and of relevant countermeasures will contribute to reducing the psychological pressures on frontline medical staff.Consequently,they will be able to cope better with outbreaks of infectious diseases in the future,to reduce the psychological pressure of the front-line medical staff,and to improve the treatment level.

Spread of Staphylococcus aureus between medical staff and high-frequency contact surfaces in a large metropolitan hospital

Objective:To examine whether bacteria are transferred between the hands of medical staff and high-frequency contact surfaces within and between departments of a major metropolitan hospital,and to further analyze the patterns of cross-transmission.Methods:Microbiological samples were collected from the hands of 112 hospital employees as well as from 120 high-frequency contact surfaces in four hospital departments.Samples were collected on agar plates,analyzed for the presence of Staphylococcus aureus or methicillin-resistant S.aureus(MRSA)by standard microbiology testing,and partially genotyped using pulsed-field gel electrophoresis.Results:Genetically identical MRSA was identified on the surface of an electrocardiography device in the medical intensive care unit and on the same type of device in the neurosurgical unit.Genetically similar S.aureus was identified on an infusion pump in the medical intensive care unit and on the hands of several doctors in a different department who regularly use that pump.Genetically identical S.aureus was also identified on bedside rail restraint in the medical intensive care unit and on the hands of the nurse in the neurosurgical unit.Finally,genetically similar MRSA was identified both on the surface of an electrocardiography device and on the suction apparatus in the medical intensive care unit.Conclusion:Cross-contamination of S.aureus or MRSA on medical workers'hands and contact surfaces was demonstrated within and between departments of a large metropolitan hospital.Improvements are needed in medical staff hygiene habits and in the cleaning of highfrequency contact surfaces to help prevent and control nosocomial infections.

Stressors and Coping Strategies of Medical Staff in the COVID-19 Pandemic in Wuhan

Exploring whether medical staff perceive stress on the assigned medical tasks,what are the specific sources of stress,what are the tangible sources of support they expected to be helpful,and individual coping with stress to provide more accurate,personal support for psychological crisis.This study uses a cross-sectional descriptive survey adopting convenience sampling among the medical staff who worked for over seven days in the infected areas of one Grade 2A and three Grade 3A hospitals during the COVID-19 pandemic.The assessment includes attitude when receiving tasks,major stressors,factors relieving stress,and personal management of stress.A total of 104(76.8%)valid questionnaires are received.A majority(94.3%)of the medical staff held a positive attitude taking duty for granted but feeling nervous and afraid(81.1%).Contacting the infected(90.6%)and compensation(92.5%)are the main concerns.The major pressure sources are regarding safety for oneself(98.1%),colleagues(92.5%),and family(94.3%),as well as lack of effective treatment(92.5%),inadequate protective equipment(94.3%)and incomplete disinfection(94.3%).The main positive pressure adjustments include strict infection controlling measures(98.4%),maintaining a positive attitude(95.2%),actively attain more information 95.2%,and engage in recreational activities(93.6%),but more than 40%takes negative adjustments to vent their emotions and relieve anxiety,suggesting the importance of early psychological intervention.During the COVID-19 pandemic,the main stressors among medical staff are safety,uncertainty and shortage of resources.Positive coping includes taking effective protective measures and achieving thorough understanding of the virus.

Impact of nurse staffing on reducing infant, neonatal and perinatal mortality rates: Evidence from panel data analysis in 35 OECD countries

Objectives:To investigate the magnitude of effect nurse staffing had on decreasing the newborn mortality rates in member countries of Organisation for Economic Co-operation and Development(OECD).Methods:The statistical technique of panel data analysis was applied to explore the possibility of association between the number of nurses'density per 1,000 population and infant,neonatal and perinatal mortality rates(IMR,NMR and PMR)per 1000 births.The observations of 35 OECD countries were collected over the period of 2000 through 2016.Results:There were significant associations between nurse staffing and IMR,NMR and PMR i.e.a 1%increase in nurse-staffing level reduced IMR,NMR and PMR by 0.98%,0.97%and 0.96%,respectively.Furthermore,the role of nursing-related services in declining the average of newborn mortality rates were investigated at the highest level in Slovenia(-5.50),Sweden(-3.34),Iceland(-2.51),Czech Republic(-1.86),Japan(-1.64)and Finland(-1.64).Moreover,if the current relationship between nursestaffing level and newborn mortality rates are disturbed with nursing shortage(e.g.in Slovak Republic and Israel),then it takes about 17 years for the mortality rates to reduce and restore back to the previous equilibrium.Conclusions:A higher proportion of nurses'density per 1,000 population is associated with lower newborn mortality rates.In addition,the nursing-related services of Slovenia,Sweden,Iceland,Czech Republic,Japan and Finland with the highest impact on improving the health level of newborns would be good patterns for other developed countries in maternity and child health care.

Investigation of mental health status of medical staff from Hainan who aided Hubei province to fight against COVID-19

Objective:To analyze the mental health status of Hainan Provincial medical staff who aided Hubei Province to combat COVID-19.Methods:The Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS),Self-Reporting Questionnaire-20(SRQ-20)and PTSD Checklist-Civilian Version(PCL-C)were used to evaluate the mental health status of 243 medical staff who aided Hubei Province to combat COVID-19.Results:A total of 221 persons have completed the psychological assessment.The survey showed that 9.05%of the medical staff had different degrees of anxiety,16.29%had different degrees of depression,13.12%were abnormal in Self-Reporting Questionnaire-20,and 9.05%were abnormal in PTSD Checklist-Civilian Version.There were difference in scores of Self-Rating Depression Scale across different genders,age groups,profession and educational levels,But Regression analysis rejects the correlation.Conclusions:The mental health status of Hainan Provincial medical staff who aided Hubei Province to fight against COVID-19 was abnormal,regardless of gender,age,profession or education background.Preventative measures at an early stage are warranted to alleviate the psychological problems.

Nurse staffing and life expectancy at birth and at 65 years old:Evidence from 35 OECD countries

Objective: To measure the possible magnitude of the role nurse staffing has on increasing life expectancy at birth and at 65 years old.Methods: The statistical technique of panel data analysis was applied to investigate the relationship from the number of practicing nurses' density per 1000 population to life expectancy at birth and at 65 years old.Five control variables were used as the proxies for the levels of medical staffing,health care financial and physical resources,and medical technology.The observations of 35 member countries of Organization for Economic Co-operation and Development (OECD) were collected from OECD Health Statistics over 2000-2016 period.Results: There were meaningful relationships from nurse staffing to life expectancy at birth and at 65 years with the long-run elasticities of 0.02 and 0.08,respectively.Overall,the role of nursing characteristics in increasing life expectancy indicators varied among different health care systems of OECD countries and in average were determined at the highest level in Japan (0.25),followed by Iceland (0.24),Belgium (0.21),Czech Republic (0.21),Slovenia (0.20) and Sweden (0.18).Conclusion: A higher proportion of nursing staff is associated with higher life expectancy in OECD countries and the dependency of life expectancy to nursing staff would increase by aging.Hence,the findings of this study warn health policy makers about ignoring the effects nursing shortages create e.g.increasing the risk of actual age-specific mortality,especially in care of elderly people.
