This likely contributed significantly to avoiding the occurrence of nosocomial infection.

Infection control and prevention in burn victims:The role of nurses

Burn injury is a major public health concern,with an estimated 180,000 deaths each year associated with burn-related infections.The majority of these occur in low-and middle-income countries,and almost two-thirds occur in the World Health Organization African and South-East Asia Regions.There is a risk of an escalation of burn injury site infections if nurses who are directly involved in burn care do not develop a mechanism to mitigate this risk in the coming years.Hence,this study aims at explaining what burn injuries are and how nurses can prevent the occurrence of infection among burn victims.This review analyzed published studies using keywords such as burn injury,infection in burn patients,and nurses’involvement in infection prevention and control(IPC)on search engines such as PubMed,Science Direct,and Google Scholar.The literature was retrieved and reviewed for eligibility to capture just the variables indicated in this seminar objective;the date range chosen in the literature search was from 2015 to 2023.The study found that many patients die from burn injuries as a result of exposure to infection and most nurses are not adequately informed about infection control.The study also found that nurses’responsibilities include proper hand hygiene,wound care,the use of personal protective equipment,antibiotic medication,cleaning the patient’s surroundings,and preventing patient cross-contamination.Burn injuries pose a significant risk to patients,necessitating infection control and prevention.Therefore,nurses in burn units should be informed on IPC practices and also educate patients,families,and coworkers on their importance.

Effect and Significance of Comprehensive Training in Infection Prevention and Control on the Psychological Health of Oral Health Staff

Background:Oral health staff have close contact with patients in the process of diagnosis and treatment,and it is inevitable for them to come into contact with patients’secretions.Therefore,oral health staff are at greater risk of infectious diseases in their daily work,and their psychological health is also greatly challenged.Objective:To study the effect and significance of comprehensive training in infection prevention and control on the psychological health of oral health staff.Methods:We selected 400 oral health staff from a tertiary stomatological hospital in Guangzhou,China in this study.The respondents were randomly divided into an intervention group and a control group.After the first round of investigation,the intervention group received comprehensive training in prevention and control of infection for three months,while the control group received no intervention.Results:The comprehensive training in infection prevention and control improved the respondents’psychological health and job satisfaction.Further strengthening infection prevention and control training for oral health staff will increase their self-confidence,improve their mental health,and increase their job satisfaction.Conclusion:For oral health staff,it is particularly important to formulate an effective and operable preventive and control training program and then implement it in a standardized manner.

Investigation and Analysis of the Status Quo of Prevention and Control Practices of Catheter-Line Associated Bloodstream Infections (CLABSI) in Guangxi, China

The prevention and control of catheter line-associated bloodstream infections (CLABSI) have become the key content of medical care and have become the core improvement goal of nursing quality control. However, the prevention and control status of CLABSI in hospitals of different grades in Guangxi is not clear. In this study, we aim to investigate central venous catheter (CVC) placement and disinfectant use in second and third-level hospitals in Guangxi. This survey was conducted on the second and third-level hospitals in Guangxi, China from 13th April 2021 to 19th April 2021. The results show that a total of 283 questionnaires were collected, including 206 secondary hospitals and 77 tertiary hospitals. In terms of the CVC, tertiary hospitals were able to place CVC entirely under the guidance of B-ultrasound, which was 24 (31.6%) and secondary hospitals were 26 (20.6%). In secondary hospitals, Most CVC placements were performed in operating rooms 94 (74.6%) and 65 (85.5%) on the third level hospital, but 32.5% of secondary hospitals and 48.7% of tertiary hospitals were selected at the bedside of patients in general wards, and 27.8% of the second-level hospital, 43.4% of third-level hospitals was done in general ward treatment rooms, only 61.9% of secondary hospitals and 64.5% of tertiary hospitals could fully achieve the maximum sterile barrier. In terms of skin disinfectants, only 36.0% of tertiary hospitals and 16.4% of second-level CVC-operators chose > 0.5% chlorhexidine alcohol. In conclusion, the prevention and control of catheter line-associated bloodstream infections (CLABSI) in Guangxi are not ideal. The prevention and control department should increase training, implement guidelines and standardize management to reduce the incidence of CLABSI.

Infection Prevention Strategy in General Hospital under Regular Epidemic Prevention and Control

New coronavirus pneumonia spread rapidly all over the world in the first half of 2020, which is a new respiratory disease with strong infectiousness. At present, the epidemic situation in China has been effectively controlled, but the global epidemic situation remains grim, and the National Health Commission has instructed that the prevention and control of new coronavirus pneumonia should become normalized. As outposts for surveillance of public health events, hospitals are an important front in the fight against the epidemic. Therefore, it is very crucial to construct infection prevention and control system actively to contain the outbreak. This paper analyzes and summarizes the normal prevention and control management strategy of Infection Control Branch Management (hereinafter referred to as Hospital Infection-Control Dept) in a certain designated comprehensive third-grade hospital in Guangdong Province and transforms the prevention and control means in emergency state into measures for sustainable development, which also provides basis and reference for Hospital Infection-Control Dept of medical institutions to formulate prevention and control guidelines.

Scenario of Infection Prevention and Control Measures for Tuberculosis in Tuberculosis Inpatient and Outpatient Department in Tertiary Care Hospital

Tuberculosis is one of the most important infectious diseases in our country. Also nosocomial infection by tuberculosis can occur, which can be prevented by implementing simple, effective and affordable tuberculosis infection control measures in health care facilities. To evaluate the effectiveness of infection control measures, such study was planned. Questionnaires were administered to all doctors, healthcare workers and servants working in outdoor and indoor department of tuberculosis at tertiary care hospital to assess the knowledge, attitudes and practices on prevention and control of Tuberculosis infection. A scoring system was devised to grade them. One-time audit was also done in outpatient and inpatient department. The analysis showed scoring of poor for doctors, good for nurses and poor forward aids. There is a need to develop strategies for training of health care workers on regular basis in order to reduce the incidence of nosocomial infections. Audit result shows a good level of environmental control measures. Better knowledge, attitude and practices are helpful for the prevention and control of tuberculosis. Also environmental control measures are helpful to prevent infection.

Management strategy of prevention and control of nosocomial infection of COVID-19 in blood purification center

There are many patients in the blood purification center who need maintenance hemodialysis to maintain life. Those patients generally havelow resistance and are easily exposed to coronavirus because they go back and forth the hospital and residence three times a week andclosely contact with family, caregivers, community personnel, people in various means of transportation, medical staff, and other patientsvisiting hospital. Therefore, the blood purification center has become a high‑risk environment for the spread of COVID-19 infection. In viewof this, our center quickly responded to the formulation and implementation of infection prevention and control measures suitable for thecharacteristics of the blood purification center and continuous renal replacement therapy (CRRT) emergency plan for fever and suspectedpatients. According to these measures, we have a positive effect on preventing and controlling nosocomial infection in the blood purificationcenter.

Survey revealed that the infrastructure for infection control program in Saudi Arabian hospitals remained underdeveloped. There were defects in the identified components of effective infection control programs.

Clinical Research of Pre-Hospital Emergency Care, Nursing, Infection Prevention and Control for Senile Osteoporotic Vertebral Compression Fracture during Epidemic Period

Background: Novel coronavirus pneumonia (NCP) and osteoporotic vertebral compression fractures (OVCF) are the high incidences of diseases in the elderly. During the epidemic period, if not treated in time, the complications are high and the mortality is high. If we do not pay attention to infection prevention and control in pre-hospital emergency care, it will lead to the first time infection of medical staff and in-hospital cross infection in emergency outpatient receiving area. The correct consideration of both and the establishment of perfect pre-hospital emergency treatment and infection prevention and control synchronous strategy is an important premise to ensure the stable, orderly and safe medical treatment. Objective: To explore the effect of synchronous implementation of pre-hospital emergency care, nursing and infection pre-vention and control for senile OVCF during the epidemic. In order to improve the efficiency of pre-hospital emergency care and prevent the spread of infection. Method: A total of 92 elderly patients with OVCF who received pre-hospital treatment in 18 hospitals in Zhangjiakou City during the epidemic prevention and control period from January 2020 to November 2022 and met the inclusion criteria were selected as research objects, including 24 males and 68 females, aged 65 - 82 (74.2 ± 2.2) years. All patients were associated with concomitant injuries and underlying diseases. All patients in this group underwent predictive pre-hospital rescue and infection prevention and control procedures. Results: All the 92 elderly patients with OVCF received timely pre-hospital treatment during the epidemic period, and no aggravation occurred of the 92 patients, 35 were in the high risk area, 10 were in the medium risk area, and 47 were in the low risk area. Exclude OVCF for NCP Patients were treated according to the conventional diagnosis and treatment principles. Suspected and confirmed cases are transferred to designated surgical hospitals for treatment. All patients were followed up 3 months, 6 months and 12 months after treatment. There was no death rate, high satisfaction of pre-hospital first aid, high diagnostic accuracy, and good curative effect. None of the rescue personnel had any infection rate, and no hospital infection transmission and nosocomial cross infection occurred. Conclusion: It is the first step to safely treat patients and prevent cross infection to establish a perfect synchronous strategy of pre-hospital first aid and infection prevention and control.

The Application of the “3 + 1” Mode in the COVID-19 Epidemic Prevention and Control at the Infection Ward of a Designated Comprehensive Hospital for COVID-19 Treatment

Objective: We assess the application effect of the “3 + 1” mode in the COVID-19 epidemic prevention and control at the infection ward of a designated comprehensive hospital for COVID-19 treatment. Method: Based on the features of the inpatients of the infection ward and their relatives, a “3 + 1” mode for the COVID-19 prevention and control is developed to conform to the demands for epidemic prevention and control and the overall prevention and control scheme of the whole hospital. Here, “3” stands for the epidemic prevention and control system, personnel management, and prevention and control measures;“1” stands for COVID-19 testing. Result: From March 1, 2020 to March 31, 2021, a total of 3056 patients were hospitalized in the three infection wards. Among them, 265 patients had a fever, and 113 patients had respiratory symptoms. None of them were infected with COVID-19. The participation rate of the test about the knowledge related to COVID-19 and the knowledge mastery rate were both 100% among the medical staff. None of the inpatients and their companions or the medical staff was diagnosed with COVID-19. Conclusion: Thus the “3 + 1” mode proves successful for avoiding nosocomial infection and the spread of the epidemic.

Health Facilities Readiness to Implement Standard Precautions for Infection Prevention and Control in Tanzania: Lesson Learnt from SARA Reports

Introduction: Standard Precautions are a set of measures applied in the care of all individuals/patients regardless of their infectious status aiming at preventing healthcare workers and patients from infections, preventing environmental contamination and spread of infections to the community. Many health facilities have not implemented them to an acceptable level. The purpose of the study is to report progress of improvement in health facilities readiness to implement standard precautions for infection prevention and control based on SARA reports. Methods: We generated mean scores of all standard precautions each year and calculated their standard deviations, variances and confidence intervals. One-way ANOVA was used to determine if the mean scores were equal. Finally, the trend of improvement in health facilities readiness to implement the standard precautions was generated. Results: A total of nine standard precautions were reported in SARA reports for 2012, 2017 and 2020. The mean scores of the standard precautions were 52.22% in 2012, 64.55% in 2017 and 69.66% in 2020. The overall trend showed an increase in health facilities readiness to implement standard precautions, although the mean scores were not statistically different (p-value 0.3217). Conclusion: SARA surveys conducted in Tanzania in 2012, 2017 and 2020 have shown an overall increase in health facilities readiness to implement standard precautions. Safe final waste disposal was being done in fewest facilities while single-use or auto-disable syringes were in most facilities that were sampled in all years. SARA surveys may be a useful way to evaluate Infection Prevention and Control adherence in health facilities.

Jordanian Nurses’ Knowledge of Preventing Surgical Site Infections in Acute Care Settings

Background: Surgical Site Infection (SSI) is one of the most common healthcare-associated infections, its account for up to 16% of all healthcare-associated infections worldwide. The SSIs can contribute to post-operative morbidity, prolonged recovery, delayed discharge and increasing cost. Nurses’ knowledge of the evidence-based recommendations is necessary to provide high-quality nursing care. Aims: To assess the level of Jordanian nurses’ knowledge regarding evidence based guidelines for the prevention of SSIs, to describe the relationship between nurses’ knowledge and selected sociodemographics, to examine the differences in nurses’ knowledge with respect to selected dichotomized variables, and to identify the most significant predictors of Jordanian nurses’ knowledge regarding evidence based guidelines for the prevention of SSIs. Design: Cross-sectional design. Sample: Two hundred registered nurses at four targeted hospitals were recruited conveniently. Results: The mean of the total knowledge scores of the sample was 3.28 out of nine (SD = 1.72, range = 0 - 7), the median was 3 out of nine. There were a statistically significant correlation between all tested continuous sociodemographics variables and the total knowledge score (p > 0.05). There is a significant difference in nurses’ knowledge between those who are attending to special surgical related training course and who are not. The most significant predictors of Jordanian nurses’ knowledge were: the number of credit hours attended by nurses for surgical-related training courses and the total years of work experience in nursing. These variables explained 16.7% of variance. Conclusion: The results of this study shed light on the obstacles that hampers the Jordanian nurses’ knowledge regarding evidence based guidelines for the prevention of SSIs in acute care settings. However, the successful implementation of infection control measures, particularly SSIs prevention measures, and well-structured continuing education programs are considered as a substantial element that would improve nurses’ knowledge.
