Clinical education is an essential part of medical science education and the climate in clinical environments is one of the influential factors in the quality of clinical education. Therefore, this study was conducted with the aim of determining the educational climate of the operating rooms from the perspective of residents, operating room, and anesthesiology students of Ardabil University of Medical Sciences in 2023.

In this cross-sectional study, all the residents from different fields, operating room students, and anesthesiology students with at least one semester of operating room experience were studied through the census survey method. Data was collected using the demographic characteristics questionnaire and the educational climate of the operating room questionnaire of Igor et al. (2022). Data were analyzed using SPSS v.26 using centrality indices, dispersion and chi-square tests, t-test, and ANOVA.

The results showed that the majority of students (98.7%) rated the educational climate of the operating rooms as average. The areas of the educational climate in this study were technically average but not optimal. The scores for educational processes and operating room infrastructure were lower than standard values (p<0.05). There were significant differences between educational climate with gender (p=0.003) and age (p=0.001). The perception of the educational climate for anesthesiology students was lower than that of other students (p=0.001).

The results showed that the educational climate of the operating rooms was not favorable from the perspective of students. There was a weakness in the educational process and operating room infrastructure. Educational authorities are recommended to address the existing problems to improve the educational atmosphere of the operating rooms and improve the quality of clinical education.

Waste anesthetic gases (WAGs) are known as one the most important air pollutants in operating rooms. This study was to evaluate occupational exposure to WAGs in the operating room of a hospital in Shiraz, Iran, by measuring the urine concentration of nitrous oxide, isoflurane, and sevoflurane. 

This is a descriptive-analytical study with a cross-sectional design that was conducted on 60 people divided into two groups of 30 including exposed group (operating and recovery rooms staff) and non-exposed or control group (administrative staff). Urine samples were collected at the end of the morning shift (after at least three hours of exposure). Urine samples were analyzed by gas chromatography–mass spectrometry method (Agilent 5977B device, paired with a headspace autosampler.  Data analysis was conducted in SPSS software, version 21. 

Urinary concentrations of nitrous oxide, isoflurane, and sevoflurane were found to be 175.8±77.52 μg/L (ranged 7.98-319.91), 4.95±3.43 μg/L (ranged 0.78-14.9) and 15.0 3±16.06 μg/L (ranged 0.76-46.40).

The operating room personnel of the selected hospital are exposed to high concentration of WAGs (nitrous oxide, isoflurane and sevoflurane).

Hospital air contains bioaerosols that are potential infection sources for patients and staff. This study focused on identifying and quantifying bacterial bioaerosols in Montaserieh Hospital, Mashhad, in 2021.

This cross-sectional analytical study collected 96 air samples from operating rooms and wards using a sampling pump with a flow rate of 28.3 L/min and a single-stage Anderson impactor by NIOSH0800 guidelines. The samples were cultured, and bacterial colonies were quantified as colony-forming units per cubic meter (cfu/m³). Data analysis was performed using SPSS software.

Predominant bacterial bioaerosols identified included Micrococcus lotus, Coccoriacristina, and Staphylococcus hominis. The mean density of bioaerosols was 57.81 cfu/m³ (standard deviation = 42.44), aligning with World Health Organization guidelines. The intensive care unit exhibited the highest average density at 101.08 cfu/m³ (standard deviation = 48.93), whereas the bone marrow transplant ward had the lowest at 5.25 cfu/m³ (standard deviation = 7.96). 

The study revealed varying densities of bacterial bioaerosols across different hospital wards, though the types of bacteria were consistent. Variations in bioaerosol density likely relate to the number of patients and staff per room, the quality of ventilation, and environmental sanitation standards.  

Musculoskeletal disorders are among the common problems in most work environments and work ability is considered a factor affecting the performance and productivity of employees. In the present study, the status of these two components and their relationship with each other in the staff working in the operating room were investigated.

The current cross-sectional study was conducted in the winter of 2023. In this research, 96 employees working in the operating rooms of government hospitals in Hamadan, Iran were enrolled by census sampling method based on the inclusion criteria. The data were collected through the Nordic standard questionnaire and the work ability index questionnaire. The collected data were analyzed in SPSS software (version 24) at two levels of descriptive (frequency, mean, and standard deviation) and inferential (t-test) statistics.

In this study, 4 (4.2%) of the participants had one musculoskeletal disorder and the remaining 91 personnel (95.8%) had more than one disorder in their musculoskeletal systems. Average work ability index was 42.3±04.91. The results of the independent t-test showed that the work ability index among people with pain in the neck (P=0.003), shoulders (P=0.001), elbows (P=0.038), back (P=0.011), knees (P=0.001), and legs (P=0.002) were less than those without pain in these organs.

Results indicated the need to pay more attention to the implementation of ergonomic work environment and management interventions to reduce the prevalence of musculoskeletal disorders and thereby increase the efficiency and effectiveness of personnel.

The clinical skills of surgical technologists, in the role of scrubs and circulars, play an essential role in the success of surgery; Therefore, this study was conducted to examine the clinical skills of orthopedic surgical technologists in the operating room of selected hospitals of Isfahan University of Medical Sciences.

Methods and Materials:

 This study was conducted as a cross-sectional analysis. 26 surgical technologists working in the orthopedic operating room, who met the inclusion criteria, were selected and included in the study through convenient sampling method. Data collection tool was a researcher-made checklist of clinical skills that included 85 items with a 4-point Likert scale (50 questions related to the circular person and 35 questions related to the scrub person).

The average age and work experience of the participants in this study were 29.38 ± 4.95 and 6.42 ± 5.72, respectively. Most of the participants were female (73.1%), most of them had a bachelor’s degree (92.3%) and they were in the workforce (50%). The average clinical skill scores of operating room technologists in the role of circular (in the range of 0-150) and scrub (in the range of 0-105) were 137.27 ±11.24 and 99.69 ± 5.06, respectively. Moreover, they were at the optimal level. The results showed that th average clinical skill scores are more in women than men; however, the t-test did not show a significant difference between the two groups (P=0.56). There is also a significant negative relationship between age and work experience with circular and scrub skills(P<0.001).

The results of this study showed that the orthopedic surgical technologists of selected hospitals in Isfahan have optimal clinical skills in both circular and scrub roles. In addition, there is a significant correlation between factors such as age, gender, and work history and education level with the clinical skills of the personnel. Therefore, it is suggested to plan and implement specialized training courses by respected hospital officials to improve the clinical skills of orthopedic surgical technologists in both circular and scrub roles and achieve an ideal level of skills.

One of the basic principles in the safety of drug therapy for patients is the correct registration and labeling of anesthetic drugs, which can lead to the reduction of drug errors, the increase of drug and patient safety, the reduction of drug consumption and the environment, and the optimization of hospital costs.

This descriptive-analytical and cross-sectional research was conducted in February 2022 in the operating rooms of Iran University of Medical Sciences hospitals. The participants included 177 Anesthesia experts working in the hospitals’ operating rooms, who were included in the study by census method. The data was collected using the checklist for evaluating anesthetic drug registration and labeling guidelines and analyzed using SPSS software and one-way ANOVA, Fisher, and Pearson correlation coefficient statistical tests. The significance level was considered P value < 0.05.

The average compliance with the guidelines for registration and labeling of anesthetic drugs in all hospitals was 3.559 out of the total score of 16. The average adherence to guidelines in 8 hospitals was significantly different from each other (P < 0.001). Hazrat Ali Asghar Hospital had the highest compliance rate, averaging 10.333 out of 16. Firouzgar and Shahid Akbarabadi hospitals were in the next rank, averaging 10.11 and 6.65, respectively. There was a negative and significant correlation between the level of compliance with the guidelines and the average work experience and age of the experts (P=0/17); However, gender did not significantly correlate with the degree of adherence to the guidelines(P=0/596).

According to the obtained results, compliance with the guidelines for registration and labeling of anesthetic drugs in most hospitals was assessed as weak and at an unfavorable level. Considering the importance of this issue in reducing medication errors and increasing patient safety, it is necessary to use empowerment and retraining courses for Anesthesia experts according to the latest guidelines.

Training and improving the surgical team's awareness of radiation protection is necessary to prevent severe and irreparable damage. Therefore, the purpose of the present study was to compile and psychometrically evaluate (content and face validity) the educational booklet on the principles of radiation protection to promote the knowledge and culture of radiation safety of the operating room staff and prevent injuries.

 The current research is a methodology carried out in Iran University of Medical Sciences in 2022-2023 in three stages: first, the content of the educational booklet was selected based on the needs of the target audience, and the related articles and sources were reviewed. Then, the initial draft of the educational manual was designed and prepared. After that, expert judges in related fields as well as anesthesia and operating room technologists evaluated the formal and content validity of the manual. The content validity index at the item level (I-CVI) and the content validity index at the scale level (S-CVI) equal to or greater than 0.78 and 0.9, respectively, were considered as criteria for validity of the booklet. The binomial test was used to check the reliability of the content validity index of the items so that the significance level was 0.05 and the expected agreement ratio was 0.8. Data were analyzed using SPSS 26 software.

In this research, 22 experts in related fields and 22 anesthesia and operating room technologists with an average work experience of 13.8±4.3 years and 15.6±6.3 years participated, respectively. After sending and receiving the draft version of the booklet along with its evaluation scale, the specialists and experts participating in the study were given the minimum values of I-CVI and S-CVI values for the desired scale items to check the face validity and content of the booklet. According to experts, it was equal to 0.9 and 0.97, respectively. The minimum observed agreement ratio of the binomial test was 0.9, which was more than the expected agreement ratio (0.8). The values of I-CVI, S-CVI, and agreement ratio between anesthesia and operating room technologists were all equal to 1.

The present educational booklet has an acceptable form and content validity based on the research findings. Therefore, it can be used as a simple tool to promote radiation safety culture and prevent radiation damage in operating rooms.

Preventing the cancellation of surgeries is an important and devastating challenge in operating room management. Cancellation of pre-scheduled surgeries at the last moment in the operation room leads to increased length of stay, patient dissatisfaction, human resource consumption and financial burden for patients and the health care system. In this study, we have investigated the effect of recording the causes of surgery cancellations in the operation room on the incidence of surgery cancellations in patients who have been candidates for non-emergent surgeries.

A total of 545 surgeries which had been canceled in different types of surgery between March 2014 and March 2015 were recorded according to the reasons for cancellation in predetermined forms and the information was analyzed. The most common reasons for cancellation included changing the plan of treatment from surgery, a high-risk comorbidity with a high probability of mortality, patient’s refusal from surgery, an unanticipated duration of previous surgery longer than anticipated, the unavailability of an ICU bed in the hospital, requested laboratory data not being ready, failing to prepare requested packed RBCs and other hospital or patient-related problems.

The percentage of surgery cancellations in most groups including orthopedics, urology, cardiac surgery, general surgery, gynecology and maxillofacial surgery, decreased during the course of this study. According to our findings the most relevant cause of non-emergent surgery cancellation was the unpredictable increased duration of previous surgery. The maxillofacial surgery group reached the highest surgery cancellation reduction rate and the cardiovascular surgery group experienced the lowest cancellation reduction rate. Also, the percentage of surgery cancellations in the field of neurosurgery increased during the study period.

Recording the reasons mentioned by the surgical team as the reason for canceling surgeries and reducing the rate of their occurrence during the study and providing appropriate feedback and dialogue in this case had a positive effect on reducing the rate of cancellation of the surgeries and reducing the mentioned reasons.

Operating room students are very similar in terms of  learning abilities and talents, but there is a significant difference in their academic progress during the academic year, which can reflect the difference in their academic motivation. Considering the importance of the motivation for progress, the learning-learning process, the planning and implementation of educational programs, the present study aims to "investigate the relationship of academic motivation with the expectations and outcomes of undergraduate students operating room operative in Khuzestan province ".

This descriptive cross-sectional study was carried out with the participation of 225 students of operating rooms of universities in different cities of Khuzestan province and using stratified sampling method. Then the demographic information form, the academic motivation questionnaire and the students' outcomes-expectations questionnaire were completed by the students. Data were analyzed using descriptive and analytical statistics.

The results showed that 83.6% of the students had a very good motivation, 15.6% had moderate motivation and 9.9% had moderate motivation. Percentage was poorly motivated. The mean and standard deviation of academic motivation score in all students were 135.62 ± 25.15, respectively. Finally, the relationship between all the sub-scales of academic motivation and the outcome of the outcome between Khuzestan operating room students in all academic years is significant.

Considering the significant relationship between academic motivation and expectation-outcome among students in operating room of Khuzestan province in general, motivational factors affect academic achievement. Obviously, educational systems should increase their efforts to promote students' academic motivation, education, and related components - inclusive, learner, environment and educational facilities.

One of the most important measures to reduce errors in operating rooms is to identify the causes of errors and their risk factors. The present study was conducted with the aim of determining the factors affecting the occurrence of errors and the barriers to reporting them from the perspective of surgical technology and anesthesia students at Alborz University of Medical Sciences, 2022.

This is a cross-sectional descriptive study in which all verified undergraduate surgical technology and anesthesia students were enrolled by census method. Data collection tools included demographic data and factors affecting the occurrence of errors, and barriers to error reporting questionnaires. Collected data were analyzed using SPSS software version 26, descriptive, and analytical statistics with a significant level of 0.05.

270 undergraduate surgical technology and anesthesia students took a part in this study. Findings indicate that the mean of the factors affecting the occurrence of errors was 2.62±0.74, and for the factors affecting error reporting it was 2.90±0.92. The highest mean score related to the field of environmental factors (2.82±0.85) among the factors affecting the occurrence of errors; and the scope of the reporting process (3.04±1.01) was one of the barriers to reporting errors.

The results of this study showed providing standard clinical training fields can have a significant impact on reducing the occurrence of errors. On the other hand, reforming the error reporting process and encouraging students to report errors should also be a priority for the management of educational and therapeutic centers.
