Assessment effects and risk of nosocomial infection and needle sticks injuries among patents and health care worker

A Narrative Review of Burnout Syndrome in Medical Personnel

Burnout among healthcare workers has been extensively studied since its initial recognition in 1960, with its defining characteristics established by Maslach in 1982. The syndrome, characterized by emotional exhaustion, depersonalization, and low personal accomplishment, is exacerbated by work-related stress and has profound implications for individual and societal well-being.

METHODS

A review of the literature, including PubMed searches and analyses of risk factors and protective measures, was conducted to assess the prevalence, impacts, and biomarkers associated with burnout among healthcare workers. Various instruments for evaluating burnout were examined, including the widely used Maslach Burnout Inventory, alongside specific tools tailored to different occupational populations.

RESULTS

Healthcare workers, particularly physicians, exhibit significantly higher rates of burnout compared to the general population. Factors such as night shifts, workload, and exposure to biohazards contribute to elevated burnout risk. Biomarkers like cortisol, melatonin, and thyroid hormones have been linked to burnout, highlighting physiological implications.

CONCLUSIONS

Burnout poses significant challenges to healthcare systems globally, impacting patient care, worker retention, and overall well-being. Identifying and addressing risk factors while promoting protective factors such as resilience and social support are crucial in mitigating burnout. Further research into prevention strategies and biomarker monitoring is warranted to support the mental and physical health of healthcare workers.

Enabling non-invasive delivery of proteins across the mucosal barriers promises improved patient compliance and therapeutic efficacies. Cell-penetrating peptides (CPPs) are emerging as a promising and versatile tool to enhance protein and peptide permeation across various mucosal barriers. This review examines the structural and physicochemical attributes of the nasal, buccal, sublingual, and oral mucosa that hamper macromolecular delivery. Recent development of CPPs for overcoming those mucosal barriers for protein delivery is summarized and analyzed. Perspectives regarding current challenges and future research directions towards improving non-invasive transmucosal delivery of macromolecules for ultimate clinical translation are discussed.

Investigation ways of causes needle sticks injuries, risk factors affecting on health and ways to preventive

Needle sticks injuries (NSIs) has caused many health concerns, including the widespread infection disease. Needle sticks injuries can have high threaten health human especially, all those who are in contact with health and medical centers. The purpose of this review study was the determination the effects of needle sticks injuries (NSIs) on health care worker and patents. In this a review study of literature studied conducted on international databases included Google Scholar, ISI/WOS (Web of Science), Springer, Scopus, Medline/PubMed. The literature signs a notable undesirable affect from potential needle sticks injuries related to ways to preventive and risks factors among patents and health care worker. The literature was shown needle stick injuries can cause with a variety of ways including needle recapping, non-standard safety boxes, thin gloves, and inadequate personal protective equipment. According to the result this study, needle stick injuries can transfer infectious disease (Human Immunodeficiency viruses [HIV], Hepatitis C virus [HCV]) and increase risk health on health care worker and patients. According to research related to the subject, the ways to prevent reduce needle sticks include personal protective equipment, holding retraining courses for medical staff in the direction to raise awareness can significantly reduce cases of needle sticks injuries. Further research using more sophisticated methodology is warranted.

Determination and prioritization of factors affecting the occurrence of needle stick injuries among healthcare workers using techniques of Delphi and fuzzy analytical hierarchy process (FAHP)

INTRODUCTION

Needlestick injuries (NSIs) are a major hazard in the workplace for healthcare workers. To prevent these injuries, it is essential to determine the important factors affecting the occurrence of them. This study aimed to identify, classify and prioritize these factors using techniques of Delphi and fuzzy analytical hierarchy process (FAHP).

METHODS

This descriptive-analytical study was conducted in 2022. Firstly, the factors affecting the occurrence of needlestick injuries were identified by the literature review. Moreover, the Delphi technique was used to identify the factors. 20 experts (physicians, nurses, and occupational health experts) participated in the steps of the Delphi method. Then, these factors were grouped into six groups. In the next step, the fuzzy analytical hierarchy process (FAHP) was applied to prioritize the factors. For this purpose, the pairwise comparison questionnaire was designed and filled out by 20 experts. Finally, data were analyzed using MATLAB software (version 2018a).

RESULTS

42 factors (31 factors extracted from the literature review and 11 factors obtained from the Delphi technique) were identified in this study. These factors were categorized into six groups. Based on the results, the relative weight of non-demographic personal factors, tool and technology factors, job factors, organizational factors, demographic personal factors, and environmental factors were computed by 0.200, 0.185, 0.184, 0.157, 0.142, and 0.133, respectively.

CONCLUSION

These results determined the importance of the factors affecting the occurrence of needlestick injuries. These findings can be useful for planning preventive measures.

Effect of educational intervention based on health belief model on nurses' compliance with standard precautions in preventing needle stick injuries

BACKGROUND

The increasing prevalence of needle stick injuries among nurses and the arising risks double the need to pay attention to improve their knowledge and change their behavior using effective educational models. The present study aimed to investigate the effect of educational intervention based on the health belief model on nurses' compliance with standard precautions in preventing needle stick injuries.

METHODS

This quasi-experimental study was conducted on 110 nurses working in medical training centers in Shiraz and Fasa in 2019. Subjects were selected using a simple sampling method and were randomly divided into two interventions (n = 55) and control (n = 55). The intervention included 7 sessions of 50-55 min. Before and 3 months after the intervention, the health belief model questionnaire was completed by both groups. The data were analyzed using SPSS software version 22 through chi-square, independent, and paired t-tests (P < 0.05).

RESULTS

Based on independent and paired t-tests, there was no significant difference between the control and intervention groups regarding the mean score of health belief model constructs before the intervention. However, there was a significant difference regarding the mentioned scores 3 months after the educational intervention. Based on the paired t-test, the mean score of awareness, perceived sensitivity, perceived severity, perceived benefits, self-efficacy, cues to action, and behavioral performance in the intervention group significantly increased after the educational intervention (P < 0.05). Also, there was a significant decrease in perceived barriers (P < 0.05).

CONCLUSION

It is recommended to apply the proposed model as an effective and cost-effective method along with other methods in training programs for nurses and other health workers exposed to invasive procedures, contaminated blood, and secretions.

Antibacterial Screening of Isoespintanol, an Aromatic Monoterpene Isolated from Oxandra xylopioides Diels

The incidence of nosocomial infections, as well as the high mortality and drug resistance expressed by nosocomial pathogens, especially in immunocompromised patients, poses significant medical challenges. Currently, the efficacy of plant compounds with antimicrobial potential has been reported as a promising alternative therapy to traditional methods. Isoespintanol (ISO) is a monoterpene with high biological activity. Using the broth microdilution method, the antibacterial activity of ISO was examined in 90 clinical isolates, which included 14 different species: (Escherichia coli (38), Pseudomonas aeruginosa (12), Klebsiella pneumoniae (13), Acinetobacter baumannii (3), Proteus mirabilis (7), Staphylococcus epidermidis (3), Staphylococcus aureus (5), Enterococcus faecium (1), Enterococcus faecalis (1), Stenotrophomonas maltophilia (2), Citrobacter koseri (2), Serratia marcescens (1), Aeromonas hydrophila (1), and Providencia rettgeri (1). MIC90 minimum inhibitory concentration values ranged from 694.3 to 916.5 µg/mL and MIC50 values from 154.2 to 457.3 µg/mL. The eradication of mature biofilms in P. aeruginosa after 1 h of exposure to ISO was between 6.6 and 77.4%, being higher in all cases than the percentage of biofilm eradication in cells treated with ciprofloxacin, which was between 4.3 and 67.5%. ISO has antibacterial and antibiofilm potential against nosocomial bacteria and could serve as an adjuvant in the control of these pathogens.
