Evaluation of the Effectiveness of Standard Precaution Training on Disposition of Occupational Blood Exposure Among Healthcare Trainees: A Pre-Post Intervention Study

Introduction

Blood-borne occupational exposure (OBE) is one of the major public health problem for healthcare workers globally. Effective education and training on post-exposure management and standard precautions for healthcare trainees, are important measures for reducing OBE and infection rates. The aim of this study was to evaluate the effectiveness of standard precaution training on OBE disposition for healthcare trainees, comparing the differences of "theoretical teaching" and "situational simulation" training methods.

Methods

A pre-post intervention study was conducted among 1347 healthcare trainees at a university teaching hospital located in Jining, Shandong Province from July 2023 to September 2023. Healthcare trainees who were undergoing training at the hospital from July 2020 to July 2023 were selected as the research subjects. They voluntarily participated in theoretical teaching group or situational simulation group. The two groups taught the same knowledge using different methods. Both groups were tested the same content before and after the training.

Results

The accuracy rates before and after training in different groups were 71.71% and 78.08%, respectively (P<0.001). The accuracy rate after training in the scenario simulation group (79.08%) was higher than that in the theoretical teaching group (76.60%), with a statistically significant difference (P<0.05). The accuracy rate for trainees who experienced OBE was 69.87% before training and 77.11% after training. For trainees who had not experienced OBE, the accuracy rates were 71.38% before training and 77.25% after training. The accuracy rates were higher after training compared to before training, with statistically significant differences (P<0.001).

Conclusion

Scenario simulation training exhibits significant advantages in improving accuracy due to its strong practicality, high level of participation, and timely feedback. The self-protection awareness, knowledge on OBE management, and standard precaution among healthcare trainees were enhanced through the training, and operational content can achieve better results through scenario simulation training.

Epidemiology and risk factors of needlestick injuries among healthcare workers in Iran: a systematic reviews and meta-analysis

BACKGROUND

Occupational contact with blood and body fluids poses a significant risk to healthcare workers. The aim of this systematic review is to investigate the epidemiology and risk factors affecting needlestick injuries (NSI) in healthcare personnel in Iran.

METHODS

In March 2020, researchers studied six international databases such as Medline/PubMed, ProQuest, ISI/WOS, Scopus, Embase, and Google Scholar for English papers and two Iranian databases (MagIran and SID) for Persian papers. Joanna Briggs Institute (JBI) Critical Appraisal Checklist was used to assess quality of studies. The method of reporting was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement.

RESULTS

A total of 43 articles were included in the analysis. Results showed that females (OR = 1.30, 95 % CI 1.06-1.58, P value = 0.009), younger age (OR = 2.75, 95 % CI 2.27-3.33, P value < 0.001, rotated shift workers (OR = 2.16, 95 % CI 1.47-3.15, P value < 0.001), not attending training courses (OR = 1.30, 95 % CI 1.07-1.56, P value = 0.006), working in the surgery ward (OR = 1.83, 95 % CI 1.33-2.50, P value < 0.001), less work experience (OR = 1.43, 95 % CI 1.04-1.95, P value = 0.025) apposed a greater risk factors for NSI among healthcare workers.

CONCLUSION

Based on the results of this review, factors such as young age, less work experience, work shift, and female gender are considered as strong risk factors for NSI injury in Iran. Preventive measures including education programs can reduce the burden of NSI among healthcare personnel.

Prevalence and associated factors for needlestick and sharp injuries (NSIs) among dental assistants in Jeddah, Saudi Arabia

BACKGROUND

Dental personnel are subject to exposure to a number of occupational factors including needlestick and sharp injuries (NSIs). Our study aims to address knowledge gaps on prevalence and associated factors for needlestick and sharp injuries (NSIs) for the first time in Saudi Arabia.

METHODS

This cross-sectional study was conducted on a sample of 450 dental assistants recruited from 40 randomly selected private clinics in Jeddah, Saudi Arabia. Data on demographic characteristics, history of NSIs, nature of work, compliance with infection control protocols, and knowledge of infection control procedures and disease transmission were collected using a self-administered questionnaire. Logistic regression analysis was used to assess factors associated with NSIs; unadjusted and adjusted odds ratios (aORs) and their respective 95% confidence intervals (CIs) were computed.

RESULTS

About three in ten dental assistants experienced at least one NSI (29.8%, 95% CI 25.6-34.2%) in private dental clinics. Lack of adequate knowledge of infection control procedures and disease transmission, non-compliance with infection control protocol of vaccination against hepatitis B virus, and attending 12 or less number of patients daily were significantly associated with increased risk of NSIs (p ≤ 0.05); adjusted odds ratios (95% CI) were 1.87 (1.18-2.97), 1.89 (1.05-3.41), and 1.63 (1.03-2.56), respectively. In addition, dental assistants working in 45.8% of dental clinics that had no infection control unit were positively associated with higher NSI risk (aOR = 2.28, 95% CI 1.45-3.57).

CONCLUSION

Our study reported the prevalent nature of NSIs among dental assistants in Saudi Arabia and identified key factors that could be targeted to mitigate this preventable condition. Dental assistants would benefit from proper training on infection control protocols and procedures.
