Background During surgery, surgeons often work under stressful conditions, which could affect patient safety. Reducing intraoperative stress for surgeons could benefit surgeons and subsequently patients. It is difficult to study stress and stress relief in real life situations due to the multitude of confounding factors. The aim of this study was to evaluate simulated intraoperative stressors on surgeons’ stress levels and the effect of an intervention (pause including a sugar-containing drink) during standardized experiments (simulated operations). Methods An experimental interventional study was conducted using a simulator. The healthy surgeon volunteers were randomized to intervention and control in a cross-over design. Primary endpoint was salivary cortisol difference between a pause including a sugar containing drink (intervention) and controls. Secondary endpoints were change in heart rate, change in self-perceived stress measured by the State Trait Anxiety Inventory (STAI), and experience of the intraoperative pause. Endpoints were calculated with a mixed effect analysis of covariance (ANCOVA) model. Results Seventeen surgeons performed 32 experiments. There was no statistically significant difference in salivary cortisol between simulations with and without a pause including a sugar-containing drink; percent reduction, 8% (0.92 (95%CI:0.72;1.18)), p -value = 0.469. The surgeons’ self-estimation of intervention was positive, but there was no statistically significant difference in heart rate or STAI. Conclusions The surgeons’ experience of a pause including a drink was positive but there were no differences in physiological outcomes of the intervention. Lessons learned from this study could contribute to optimizing design of future studies. Trial registration Clinicaltrials.gov NCT04626648 , Registered November 6, 2020, retrospectively registered.

AIM:The impact of construction techniques on the development of stoma complications is partly undiscovered. The aim of this paper was to report and analyse the impact of the three surgical techniques in a randomized controlled trial Stoma-Const on stoma-related complications as well as identifying risk factors and patient-reported stoma function as a planned secondary analysis.METHODS:This was a randomized, multicenter trial where all patients scheduled to receive an end colostomy were invited to participate. Patients were randomized to one of three techniques for stoma construction; cruciate fascial incision, circular incision or prophylactic mesh. Stoma complications were assessed by a surgeon and stoma care nurses within 1 year postoperatively.RESULTS:Two hundred and nine patients were randomized. Patient demographics were similar in all three groups. Data on stoma-related complications were available for analysis in 201 patients. A total of 127 patients (63%) developed some type of stoma complication within 1 year after surgery. The risk ratio (95% CI) for stoma complications was 0.93 (0.73; 1.2) between cruciate vs. circular incision groups and 1.02 (0.78; 1.34) between cruciate vs. mesh groups. There were no statistically significant differences between the groups regarding parastomal hernia rate and no risk factors could be identified.CONCLUSION:This randomized trial confirmed a high prevalence of stoma-related complications but could not identify an impact of surgical technique or identify modifiable risk factors for stoma-related complications.

BACKGROUND:Little is known concerning what may influence surgeon satisfaction with a surgical procedure and its associations with intraoperative factors. The objective was to explore the relationships between surgeons' self-assessed satisfaction with performed radical prostatectomies and intraoperative factors such as technical difficulties and intraoperative complications as reported by the surgeon subsequent to the operation.METHODS:We utilized prospectively collected data from the controlled LAPPRO trial where 4003 patients with prostate cancer underwent open (ORP) or robot-assisted laparoscopic (RALP) radical prostatectomy. Patients were included from fourteen centers in Sweden during 2008-2011. Surgeon satisfaction was assessed by questionnaires at the end of each operation. Intraoperative factors included time for the surgical procedure as well as difficulties and complications in various steps of the operation. To model surgeon satisfaction, a mixed effect logistic regression was used. Results were presented as odds ratios (OR) with 95% confidence intervals (CI).RESULTS:The surgeons were satisfied in 2905 (81%) and dissatisfied in 702 (19%) of the surgical procedures. Surgeon satisfaction was not statistically associated with type of surgical technique (ORP vs. RALP) (OR 1.36, CI 0.76; 2.43). Intraoperative factors such as technical difficulties or complications, for example, suturing of the anastomosis was negatively associated with surgeon satisfaction (OR 0.24, CI 0.19; 0.30).CONCLUSIONS:Our data indicate that technical difficulties and/or intraoperative complications were associated with a surgeon's level of satisfaction with an operation.

BACKGROUND:Inter-professional teamwork in the operating room is important for patient safety. The World Health Organization (WHO) checklist was introduced to improve intraoperative teamwork. The aim of this study was to evaluate the safety climate in a Swedish operating room setting before and after an intervention, using a revised version of the WHO checklist to improve teamwork.METHODS:This study is a single center prospective interventional study. Participants were personnel working in operating room teams including surgeons, anesthesiologists, scrub nurses, nurse anaesthetists and nurse assistants. The study started with pre-interventional observations of the WHO checklist use followed by education on safety climate, the WHO checklist, and non-technical skills in the operating room. Thereafter a revised version of the WHO checklist was introduced. Post-interventional observations regarding the performance of the WHO checklist were carried out. The Safety Attitude Questionnaire was used to assess safety climate at baseline and post-intervention.RESULTS:At baseline we discovered a need for improved teamwork and communication. The participants considered teamwork to be important for patient safety, but had different perceptions of good teamwork between professions. The intervention, a revised version of the WHO checklist, did not affect teamwork climate. Adherence to the revision of the checklist was insufficient, dominated by a lack of structure.CONCLUSIONS:There was no significant change in teamwork climate by use of the revised WHO checklist, which may be due to insufficient implementation, as a lack of adherence to the WHO checklist was detected. We found deficiencies in teamwork and communication. Further studies exploring how to improve safety climate are needed.TRIAL REGISTRATION:NCT02329691.

Surgical teams’ awareness of the time needed to perform specific phases of a surgical procedure is likely to improve communication in the operating theatre and benefit patient safety. The aim of this study was to assess surgeons’ awareness of time utilization and the actual time needed to perform specific phases of an operation.

The construction of a colostomy is a common procedure, but the evidence for the different parts of the construction of the colostomy is lacking. Parastomal hernia is a common complication of colostomy formation. The aim of this study is to standardise the colostomy formation and to compare three types of colostomy formation (one including a mesh) regarding the development of parastomal hernia.
