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.

Background: Many diagnostic and treatment procedures are done in hospitals and clinics. Offering services in these areas have a prominent role in promoting patients' satisfaction levels and their prospective about health services. Objectives: This study is going to assess the satisfaction levels of patients referring to the six military hospital clinics in Iran. Materials and Methods:In this cross-sectional study, 330 outpatients and 696 inpatients admitted to the six military hospital clinics in Iran were randomly questionnaires from June to August 2008. Basic socio-demographic data along with a clinic satisfaction level assessment questionnaire were filled for outpatients. A hospital satisfaction level assessment questionnaire also was applied to record inpatients' data. All collected data were recorded and then analyzed tests X2 and ANOVAs was used and with significantly lower levels of 5% (P < 0.005). Results: We found that 96% of the study population was satisfied with clinic services and more than 98% of the respondents were satisfied with inpatient ward services. In clinic services, the satisfaction level in numbering and waiting time, access to the clinic, physical environment, welfare and helping facilities, and personnel and physicians' behavior were 78.2%, 80.6%, 89.1%, 91.2% and 93.6% respectively (P < 0.001). With regard to inpatient services, the satisfaction level of patients with physician services, nursing routine services, behavior of nurses, nutritional condition, welfare facilities, reception unit services, discharge unit services and accounting unit services were 94.7%, 91.9%, 91.9%, 91.5%, 91.5%, 91.2%, 90.8% and 88.2%, respectively (P = 0.013). Conclusions: On the basis of the findings, most respondents reported having a favorable satisfaction with clinic and hospital health services. However, planning to reduce patient's waiting time in clinics and training physicians to offer more instructions to the patients seems necessary. Since discharge and accounting unit services had the lowest satisfaction levels of inpatients services, responsible managers must have special attention to these official processes.

Background: Fatigue may lead to occupational physical trauma among the workforce. Objectives: This study was designed to explore the relationship between work-related physical trauma and fatigue in the copper extraction industry. Materials and Methods: This cross-sectional study was conducted among 453 male workers employed in the copper extraction industry in Kerman, Iran. The validated Persian version of the Piper Chronic Fatigue Scale was used for the data collection. An additional self-administrated questionnaire was prepared to obtain demographic and occupational data, including age, work experience, smoking, and history of physical trauma in the workplace. Results: The results showed that 28.5% of the participants had experienced work-related physical trauma during the past three years. Severe fatigue was most commonly reported on the subscale for life and emotions (14.79%). A higher rate of work-related fatigue was associated with physically strenuous activities and an inappropriate work place. The mean fatigue scores for subjects both with and without physical trauma experiences were 3.75 ± 0.98 and 2.86 ± 0.79, respectively (P = 0.005). Conclusions:General fatigue and its subscales had a significant relationship with workplace physical trauma among miners. Workplace physical trauma can be reduced by managing fatigue with different programs, including decreasing the workload, scheduling rest breaks at the facilities, and possibly providing welfare and entertainment opportunities for the workers.

Background Risk assessment of gas pipelines is very important because of various hazards and economic losses. Using fuzzy logic increases the reliability and accuracy of the results. The purpose of this study is to evaluate the fuzzy risk of fire, explosion and release of toxic gas in the pipeline using fuzzy analytical hierarchy process. Methodology Extraction of all hazards from HAZOP and HAZID was carried out. Fuzzy risk assessment was performed using MATLAB software. Using fuzzy hierarchy process analysis, the weight of each basic risk item (BRI) was summed up in a framework, and the fuzzy risk level was determined with a five-state criterion including highly desirable, favorable, moderate, undesirable and highly undesirable. Results The final risk score was equal to 0.1492, which according to the five-state criterion the risk level is in the favorable area. The highest risk score was related to hot work with open flame item with a risk score of 0.2485. Conclusions The final risk score of fire, explosion and release of toxic gas in Siri–Assaluyeh gas pipeline is in the optimal area. Fuzzy risk assessment, compare to conventional risk matrices, provides more data to safety managers about the hazards and their rankings. Accordingly, the results are expected to be applicable to the safety managers while making decisions related to the risk management of gas pipelines.
