Implementation of a Multimodal Interdisciplinary Massive Transfusion Protocol Educational Bundle Improves Knowledge and Self-Efficacy

PURPOSE

Critical events in the operative setting require rapid management to prevent adverse outcomes. This article describes a multimodal educational bundle that was designed and implemented to improve readiness to respond to crises involving significant blood loss. Intended outcomes of this project were to increase knowledge and self-efficacy of anesthesia providers and perioperative staff members related to the use of the massive transfusion protocol (MTP).

DESIGN

This is a quality improvement (QI) project.

METHODS

A two-part educational bundle consisted of pre-education and low-fidelity simulation (LFS) via computer-based training (CBT) modules followed by hands-on skills sessions. Anesthesia providers, registered nurses, and technicians in the operative suite completed the educational intervention. Knowledge and self-efficacy were measured pre-and-post intervention.

FINDINGS

After completing the educational bundle, the aggregated mean score on a knowledge test increased by 5.65%. Self-efficacy related to role-specific responsibilities and confidence regarding the team's ability to carry out the MTP significantly increased for all participants (n = 62).

CONCLUSIONS

This project serves as an example of how a multimodal educational bundle can improve knowledge, confidence, and readiness to respond to critical events. This model demonstrates how pre-education and LFS enable crisis management training to be readily accessible for an entire interdisciplinary team.

Identification of Meaningful Data for Providing Real-Time Intraoperative Feedback in Laparoscopic Surgery Using Delphi Analysis

Background. Surgeons are at risk of being overwhelmed with information while performing surgery. Initiatives focusing on the use of medical data in the operating room are on the rise. Currently, these initiatives require postprocessing of data. Although highly informative, data cannot be used to influence preventable error in real time. Ideally, feedback is provided preemptive. Aims. First, to identify which information is considered to be relevant for real-time feedback during laparoscopic surgery according to surgeons. Second, to identify the optimal routing for providing such feedback, and third, to decide on optimal timing for feedback to alarm users during laparoscopic surgery. Methods. A Delphi study of 3 iterations was conducted within the Amsterdam UMC, location AMC. A total of 25 surgeons and surgical residents performing laparoscopy were surveyed using 5-point Likert scales. Consensus was obtained when 80% of answers fitted the same answering category. Results. Delphi round 1 resulted in 198 unique ideas within 5 scenarios. After round 3, consensus was obtained on 102 items. Feedback most relevant during laparoscopic surgery refers to equipment like the gas insufflator, diathermy, and suction device. Feedback should be delivered via an additional monitor. Surgeons want to be instantly alarmed about aberrations in patients' vital parameters or combinations of vital parameters, preferably via a designated section on a monitor in their field of vision. Conclusions. Surgeons performing laparoscopy are uniform in their opinion that they need to be alarmed immediately when patients' vital parameters are becoming aberrant. Surgeons state that information regarding supporting equipment is best displayed on an additional monitor.

SASS: South African Simulation Survey – a review of simulation-based education

Background: Simulation-based education (SBE) has been shown to be an effective and reproducible learning tool. SBE is used widely internationally. The current state of SBE in South Africa is unknown. To the best of our knowledge this is the first survey that describes the use and attitudes towards SBE within South Africa. Methods: An online survey tool was distributed by email to: i) the South African Society of Anaesthesiologists (SASA) members; and ii) known simulation education providers in South Africa. The respondents were grouped into anaesthesia and non-anaesthesia participants. Descriptive statistics were used to analyse the data. Ethics approval was obtained: HREC REF 157/2017. Results: The majority of the respondents provide SBE and integrate it into formal teaching programmes. There is a will amongst respondents to grow SBE in South Africa, with it being recognised as a valuable educational tool. The user groups mainly targeted by SBE, were undergraduate students, medical interns, registrars and nurses. Learning objectives targeted include practical skills, medical knowledge, critical thinking and integrated management. Amongst anaesthesia respondents: the tool most commonly used to assess the quality of learner performance during SBE, for summative assessment, was ‘expert opinion’ (33%); the most frequent methods of evaluating SBE quality were participant feedback (42%) and peer evaluation (22%); the impact of SBE was most frequently assessed by informal discussion (42%) and learner feedback (39%). In anaesthesia SBE largely takes place within dedicated simulation facilities on site (47%). Most respondents report access to a range of SBE equipment. The main reported barriers to SBE were: finance, lack of trained educators, lack of equipment and lack of protected time. A limited number of respondents report engaging in SBE research. There is a willingness in both anaesthesia and non-anaesthesia groups (96% and 89% respectively) to collaborate with other centres. Conclusion: To the best of our knowledge this publication provides us with the first cross-sectional survey of SBE in anaesthesia and a selection of non-anaesthetic respondents within South Africa. The majority of respondents indicate that SBE is a valuable education tool. A number of barriers have been identified that limit the growth of SBE within South Africa. It is hoped that with a commitment to ongoing SBE research and evaluation, SBE can be grown in South Africa.

Anaesthesia in austere environments: literature review and considerations for future space exploration missions

Future space exploration missions will take humans far beyond low Earth orbit and require complete crew autonomy. The ability to provide anaesthesia will be important given the expected risk of severe medical events requiring surgery. Knowledge and experience of such procedures during space missions is currently extremely limited. Austere and isolated environments (such as polar bases or submarines) have been used extensively as test beds for spaceflight to probe hazards, train crews, develop clinical protocols and countermeasures for prospective space missions. We have conducted a literature review on anaesthesia in austere environments relevant to distant space missions. In each setting, we assessed how the problems related to the provision of anaesthesia (e.g., medical kit and skills) are dealt with or prepared for. We analysed how these factors could be applied to the unique environment of a space exploration mission. The delivery of anaesthesia will be complicated by many factors including space-induced physiological changes and limitations in skills and equipment. The basic principles of a safe anaesthesia in an austere environment (appropriate training, presence of minimal safety and monitoring equipment, etc.) can be extended to the context of a space exploration mission. Skills redundancy is an important safety factor, and basic competency in anaesthesia should be part of the skillset of several crewmembers. The literature suggests that safe and effective anaesthesia could be achieved by a physician during future space exploration missions. In a life-or-limb situation, non-physicians may be able to conduct anaesthetic procedures, including simplified general anaesthesia.

Teaching concepts in ultrasound-guided regional anesthesia

PURPOSE OF REVIEW

Ultrasound-guided regional anesthesia is a challenging, complex skill and requires competence in teaching. The aim of this study was to review current literature on identification of education and learning of ultrasound-guided regional anesthesia and to summarize recent findings on teaching concepts.

RECENT FINDINGS

Several teaching programs have been described and implemented into daily routine. Factors relevant to current practice are the knowledge of sonoanatomy, the acquisition of manual skills, the teaching ability, and the feedback given to the trainee. Simulation is a rapidly growing field and is supported by the development of phantoms. Needle visualization is one of the core competencies that is necessary for successful ultrasound-guided procedures and could be supported by technical developments in the future to improve teaching concepts.

SUMMARY

Although a lot of key questions cannot be answered by the latest study results, some interesting findings were able to improve existing education programs. These results should be tailored to the individual need of a trainee, and the effects of improved training programs on patient safety and quality of care have to be investigated. The see one, do one, teach one approach is obsolete and should be abandoned.
