Surgical safety checklists in UK veterinary practice: Current implementation and attitudes towards their use

BACKGROUND

Surgical safety checklist (SSC) use benefits veterinary patients, but endorsement and implementation are essential for these benefits to be observed.

METHODS

A cross-sectional survey assessed UK veterinary professionals' attitudes towards and usage of SSCs and identified factors associated with poorer attitude or failure to use SSCs.

RESULTS

Of 513 respondents, 70% used SSCs. Of these, 87.1% used SSCs for every surgical procedure, 19.1% adapted SSCs for different procedures and 61.1% had a standard operating procedure detailing how to use SSCs. Attitudes towards SSC use were favourable, with increased positive attitude associated with employing at least one registered veterinary nurse with a post-qualifying qualification (p < 0.001), current SSC use (p < 0.001), undertaking self-directed reading (p = 0.033) or completing SSC-relevant post-qualification continuing professional development (p = 0.005). Factors associated with veterinary practices not using SSCs included Practice Standards Scheme (PSS) non-membership (odds ratio [OR] 2.0, 1.1-3.4), no RCVS hospital status (OR 1.9, 1.1-3.5) or being a mixed first-opinion veterinary practice (OR 2.4, 1.2-5.0).

LIMITATIONS

Study limitations include sampling methodology and non-validated attitudinal scale usage.

CONCLUSION

Most respondents used SSCs. Familiarity, education and the RCVS PSS were associated with improved uptake and attitudes, but mixed practice was associated with reduced usage.

Visual Blood, Visualisation of Blood Gas Analysis in Virtual Reality, Leads to More Correct Diagnoses: A Computer-Based, Multicentre, Simulation Study

Interpreting blood gas analysis results can be challenging for the clinician, especially in stressful situations under time pressure. To foster fast and correct interpretation of blood gas results, we developed Visual Blood. This computer-based, multicentre, noninferiority study compared Visual Blood and conventional arterial blood gas (ABG) printouts. We presented six scenarios to anaesthesiologists, once with Visual Blood and once with the conventional ABG printout. The primary outcome was ABG parameter perception. The secondary outcomes included correct clinical diagnoses, perceived diagnostic confidence, and perceived workload. To analyse the results, we used mixed models and matched odds ratios. Analysing 300 within-subject cases, we showed noninferiority of Visual Blood compared to ABG printouts concerning the rate of correctly perceived ABG parameters (rate ratio, 0.96; 95% CI, 0.92–1.00; p = 0.06). Additionally, the study revealed two times higher odds of making the correct clinical diagnosis using Visual Blood (OR, 2.16; 95% CI, 1.42–3.29; p < 0.001) than using ABG printouts. There was no or, respectively, weak evidence for a difference in diagnostic confidence (OR, 0.84; 95% CI, 0.58–1.21; p = 0.34) and perceived workload (Coefficient, 2.44; 95% CI, −0.09–4.98; p = 0.06). This study showed that participants did not perceive the ABG parameters better, but using Visual Blood resulted in more correct clinical diagnoses than using conventional ABG printouts. This suggests that Visual Blood allows for a higher level of situation awareness beyond individual parameters’ perception. However, the study also highlighted the limitations of today’s virtual reality headsets and Visual Blood.

The Anaesthesia Case Report (ACRE) checklist: a tool to promote high-quality reporting of cases in peri-operative practice

Case reports have fulfilled an important role in the development of anaesthesia and continue to be highly relevant to modern practice. Despite this, they are sometimes criticised for being insufficiently rigorous to meaningfully inform clinical practice or research design. Reporting checklists are a useful tool to improve rigour in research and, although case report checklists have previously been developed, no existing checklist focuses on the peri-operative setting. In order to address the need for a case reports checklist that better accommodates peri-operative care, we used an established tool as the basis for developing the 12-item Anaesthesia Case Report checklist. This was refined using an iterative approach through feedback from journal editors with experience of handling case reports, patient and public involvement, and trialling its use on Anaesthesia Reports submissions. The Anaesthesia Case Report checklist differs from existing checklists by aligning with peri-operative practice; it places less emphasis on making diagnoses and focuses on the way in which clinical challenges, for example, related to the patient's comorbidities or operative interventions, are addressed. Adopting a standardised approach to the content of case reports presents clear benefits to authors, editors and peer reviewers through streamlining the processes involved in writing and publication. The Anaesthesia Case Report checklist provides a pragmatic framework for comprehensive and transparent reporting. We hope it will facilitate the authorship of high-quality case reports with the potential to further improve the quality and safety of peri-operative care.

Impact of repeated simulation on learning curve characteristics of residents exposed to rare life threatening situations

Background

Little is known about the learning curve characteristics of residents undertaking simulation-based education. It is important to understand the time for acquisition and decay of knowledge and skills needed to manage rare and difficult clinical situations.

Method

Ten anaesthesiology residents underwent simulation-based education to manage a cannot intubate cannot ventilate scenario during general anaesthesia for caesarean section. Their performance was measured using an assessment tool and debriefed by two experienced anaesthesiologists. The parameters against which the performance was judged were grouped into preoperative assessment, preoperative patient care, equipment availability, induction sequence, communication and adherence to airway algorithm protocol. The scenario was repeated at 6 and 12 months thereafter. The residents’ acquisition of knowledge, technical and non-technical skills were assessed and compared at baseline, 6 months and end of 12 months.

Result

The skills of preoperative assessment, preoperative care and communication quickly improved but the specific skill of managing a difficult airway as measured by adherence to an airway algorithm required more than 6 months (CI at 6 vs 12 months: −3.4 to –0.81, p=0.016). The skills of preoperative assessment and preoperative care improved to a higher level quickly and were retained at this improved level. Communication (CI at 0 vs 6 months: −3.78 to −0.22, p=0.045 and at 6 vs 12 months : −3.39 to −1.49, p=0.007) and difficult airway management skill were slower to improve but continued to do so over the 12 months. The compliance to machine check was more gradual and showed an improvement at 12 months.

Conclusion

Our study is unique in analysing the learning curve characteristics of different components of a failed obstetric airway management skill. Repeated simulations over a longer period of time help in better reinforcement, retention of knowledge, recapitulation and implementation of technical and non-technical skills.

Does an electronic cognitive aid have an effect on the management of severe gynaecological TURP syndrome? A prospective, randomised simulation study

Background

Lack of familiarity with the content of current guidelines is a major factor associated with non-compliance by clinicians. It is conceivable that cognitive aids with regularly updated medical content can guide clinicians’ task performance by evidence-based practices, even if they are unfamiliar with the actual guideline. Acute hyponatraemia as a consequence of TURP syndrome is a rare intraoperative event, and current practice guidelines have changed from slow correction to rapid correction of serum sodium levels. The primary objective of this study was to compare the management of a simulated severe gynaecological transurethral resection of the prostate (TURP) syndrome under spinal anaesthesia with either: an electronic cognitive aid, or with management from memory alone. The secondary objective was to assess the clinical relevance and participant perception of the usefulness of the cognitive aid.

Methods

Anaesthetic teams were allocated to control (no cognitive aid; n = 10) or intervention (cognitive aid provided; n = 10) groups. We identified eight evidence-based management tasks for severe TURP syndrome from current guidelines and subdivided them into acute heart failure (AHF)/pulmonary oedema tasks (5) and acute hyponatraemia tasks (3). Implementation of the treatment steps was measured by scoring task items in a binary fashion (yes/no). To assess whether or not the cognitive aid had prompted a treatment step, participants from the cognitive aid group were questioned during debriefing on every single treatment step. At the end of the simulation, session participants were asked to complete a survey.

Results

Teams in the cognitive aid group considered evidence-based treatment steps significantly more often than teams of the control group (96% vs. 50% for ‘AHF/pulmonary oedema’ p < 0.001; 79% vs. 12% for ‘acute hyponatraemia’ p < 0.001). Without the cognitive aid, performance would have been comparable across both groups. Nurses, trainees, and consultants derived equal benefit from the cognitive aid.

Conclusions

The cognitive aid improved the implementation of evidence-based practices in a simulated intraoperative scenario. Cognitive aids with current medical content could help to close the translational gap between guideline publication and implementation in acute patient care. It is important that the cognitive aid should be familiar, in a format that has been used in practice and training.

Obstetric Anaesthetists' Association and Difficult Airway Society guidelines for the management of difficult and failed tracheal intubation in obstetrics

The Obstetric Anaesthetists' Association and Difficult Airway Society have developed the first national obstetric guidelines for the safe management of difficult and failed tracheal intubation during general anaesthesia. They comprise four algorithms and two tables. A master algorithm provides an overview. Algorithm 1 gives a framework on how to optimise a safe general anaesthetic technique in the obstetric patient, and emphasises: planning and multidisciplinary communication; how to prevent the rapid oxygen desaturation seen in pregnant women by advocating nasal oxygenation and mask ventilation immediately after induction; limiting intubation attempts to two; and consideration of early release of cricoid pressure if difficulties are encountered. Algorithm 2 summarises the management after declaring failed tracheal intubation with clear decision points, and encourages early insertion of a (preferably second-generation) supraglottic airway device if appropriate. Algorithm 3 covers the management of the 'can't intubate, can't oxygenate' situation and emergency front-of-neck airway access, including the necessity for timely perimortem caesarean section if maternal oxygenation cannot be achieved. Table 1 gives a structure for assessing the individual factors relevant in the decision to awaken or proceed should intubation fail, which include: urgency related to maternal or fetal factors; seniority of the anaesthetist; obesity of the patient; surgical complexity; aspiration risk; potential difficulty with provision of alternative anaesthesia; and post-induction airway device and airway patency. This decision should be considered by the team in advance of performing a general anaesthetic to make a provisional plan should failed intubation occur. The table is also intended to be used as a teaching tool to facilitate discussion and learning regarding the complex nature of decision-making when faced with a failed intubation. Table 2 gives practical considerations of how to awaken or proceed with surgery. The background paper covers recommendations on drugs, new equipment, teaching and training.

Cognitive Aids in Medicine Assessment Tool (CMAT): preliminary validation of a novel tool for the assessment of emergency cognitive aids

Applying human factors principles to the design of clinical emergency guidelines is important. The UK Civil Aviation Authority uses a Checklist Assessment Tool for evaluating the content and usability of emergency drills before introduction into service on aircraft. We hypothesised that this model could be used to develop a generic medical tool. A three-stage modified Delphi process was used to adapt the above tool for use in designing medical emergency guidelines. The resulting Cognitive aids in Medicine Assessment Tool was then used to score and rank seven published difficult airway guidelines; the scores were used to assess its validity and reliability. Pearson's rank coefficient between these scores and scores from independent assessors was 0.89 (p = 0.007). Internal consistency, as assessed by Cronbach's alpha, was 0.74, 0.96 and 0.72 for the tool's three constituent domains of physical characteristics, content and layout/format, respectively. Inter-rater reliability, as assessed by Cohen's kappa, ranged from 0.33 to 0.72. The adoption of our tool has the potential to improve the usability of medical emergency guidelines.
