ABSTRACT This study explores the volume-outcome relationship for gastric bypass surgery for obesity to determine whether higher-volume hospitals, higher-volume surgeons, or both are associated fewer adverse outcomes.
The Pennsylvania state discharge database was used to identify 4685 cases of gastric bypass surgery for obesity between 1999 and 2001. Statistical modeling analyses were used to determine whether mortality or adverse outcome rate was significantly related to hospital and surgeon volume; the data were controlled for risk factors such as age, gender, comorbidities, and others.
There were 28 deaths (0.6%) and 813 adverse outcomes (17.4%). There was a significant risk-adjusted relationship between surgeon volume and adverse outcome, and the same trend was observed for deaths. Surgeons who performed fewer than 10 procedures per year had a 28% risk of adverse outcome and a 5% risk of death, compared with 14% (P<.05) and 0.3% (P=.06), respectively, for high-volume surgeons. Hospital volume did not reach significance, but there was a striking interaction between surgeon and hospital volume; surgeons who performed 10 to 50 cases per year operating in low-volume hospitals had a 55% risk of adverse outcome (P<.01).
Risk-adjusted in-hospital adverse outcome is significantly lower when gastric bypass is performed by higher-volume surgeons.

    ABSTRACT: Background Surgical errors result from faulty decision-making, misperceptions and the application of suboptimal problem-solving strategies, just as often as they result from technical failure. To date, surgical training curricula have focused mainly on the acquisition of technical skills. The aim of this review was to assess the validity of methods for improving situational awareness in the surgical theatre.MethodsA search was conducted in PubMed, Embase, the Cochrane Library and PsycINFO® using predefined inclusion criteria, up to June 2014. All study types were considered eligible. The primary endpoint was validity for improving situational awareness in the surgical theatre at individual or team level.ResultsNine articles were considered eligible. These evaluated surgical team crisis training in simulated environments for minimally invasive surgery (4) and open surgery (3), and training courses focused at training non-technical skills (2). Two studies showed that simulation-based surgical team crisis training has construct validity for assessing situational awareness in surgical trainees in minimally invasive surgery. None of the studies showed effectiveness of surgical crisis training on situational awareness in open surgery, whereas one showed face validity of a 2-day non-technical skills training course.Conclusion To improve safety in the operating theatre, more attention to situational awareness is needed in surgical training. Few structured curricula have been developed and validation research remains limited. Strategies to improve situational awareness can be adopted from other industries.

    ABSTRACT: Introduction: Robotic surgery is a rapidly expanding field. Thus far training for robotic techniques has been unstructured and the requirements are variable across various regions. Several projects are currently underway to develop a robotic surgery curriculum and are in various stages of validation. We aimed to outline the structures of available curricula, their process of development, validation status and current utilization. Methods: We undertook a literature review of papers including the MeSH terms “Robotics” and “Education”. When we had an overview of curricula in development, we searched recent conference abstracts to gain up to date information. Results: The main curricula are the FRS, the FSRS, the Canadian BSTC and the ERUS initiative. They are in various stages of validation and offer a mixture of theoretical and practical training, using both physical and simulated models. Discussion: Whilst the FSRS is based on tasks on the RoSS virtual reality simulator, FRS and BSTC are designed for use on simulators and the robot itself. The ERUS curricula benefits from a combination of dry lab, wet lab and virtual reality components, which may allow skills to be more transferable to the OR as tasks are completed in several formats. Finally, the ERUS curricula includes the OR modular training programme as table assistant and console surgeon. Conclusion: Curricula are a crucial step in global standardisation of training and certification of surgeons for robotic surgical procedures. Many curricula are in early stages of development and more work is needed in development and validation of these programmes before training can be standardised.
