The aim of this study is to identify the methods and content of hospital-based serious incident reviews involving mental health related homicide where a service user was the perpetrator between 2007 and 2017. Eleven reports were obtained from mental health services in New Zealand's largest city and thematically analysed. Nine used the London protocol to identify clinical and system factors that may have contributed to the serious incident, but there was considerable variation in the way in which it was applied. Feedback to services was inconsistent. The voices of family members of the victims were largely absent and consideration of cultural context was missing. A structured protocol to specifically address the mental health context in New Zealand and internationally could resolve some of these issues and lead to a process that is more likely to provide comprehensive coverage of relevant matters and produce clear recommendations to effect improvements to services.

Inquiries into mental health related homicides may be held to identify failures in care and areas for improvement, accountability and to enhance public confidence. However, inquiries do not always achieve these aims. The aim of this study was to explore the perspectives of members of inquiry panels who conduct inquiries into mental health related homicides in order to identify elements that would constitute a good inquiry. We selected a sample of inquiry panel members comprising 15 senior clinicians, legal experts and consumer advisors. Semi-structured interviews were audio-recorded, transcribed and analysed using thematic analysis. Participants raised concerns related to: (1) orientation of the panel to the inquiry task; (2) clarity of the process; and (3) impact of the inquiry. Most participants recognised that inquiries require a focus on mental health systems and sensitivity to families and clinicians. They reported difficulties in clarifying purposes, attending to cultural aspects of the case, having a clear method tailored to the mental health context, formulating recommendations and disseminating findings. Our participants perceived a number of weaknesses in the process by which inquiries into mental health related homicides had been conducted, and recommendations formulated and implemented. There is an opportunity to address these and thereby potentially improve the effectiveness and value of inquiries. [ABSTRACT FROM AUTHOR]

We aimed to identify features of New Zealand government-commissioned inquiries into the provision of mental health services after homicides committed by service users. The analysis of five reports from 1992 to 2016 identified similarities across reports, which included documenting a process; responding to a set terms of reference; detailing a case chronology, risk assessment, team and system issues; making recommendations and giving opportunities to clinicians to respond to adverse comments. Differences included selecting key informants and acknowledging limitations of scope. The inquiries did not specify a means to disseminate findings to stakeholders and follow up recommendations. Unrealised opportunities include attention to relationships between stakeholders and ways to support learning from inquiries. There is no standardised approach to conducting statutory inquiries into mental health services following a homicide. This limits the value of such inquiries for learning and service improvement. We recommend a standardised framework be developed to guide inquiries. [ABSTRACT FROM AUTHOR]

Although recent trials comparing on vs. off-pump revascularization techniques describe cardiopulmonary bypass (CPB) as "conventional," inadequate description and evaluation of how CPB is managed often exist in the peer-reviewed literature. We identify and subsequently describe regional and center-level differences in the techniques and equipment used for conducting CPB in the setting of coronary artery bypass grafting (CABG) surgery. We accessed prospectively collected data among isolated CABG procedures submitted to either the Australian and New ZealandCollaborative PerfusionRegistry (ANZCPR) or Perfusion Measures and outcomes (PERForm) Registry between January 1, 2014, and December 31, 2015. Variation in equipment and management practices reflecting key areas of CPB is described across 47 centers (ANZCPR: 9; PERForm: 38). We report average usage (categorical data) or median values (continuous data) at the center-level, along with theminimum andmaximum across centers. Three thousand five hundred sixty-two patients were identified in the ANZCPR and 8,450 in PERForm. Substantial variation in equipment usage and CPB management practices existed (within and across registries). Open venous reservoirs were commonly used across both registries (nearly 100%), as were "all-but-cannula" biopassive surface coatings (>90%), whereas roller pumps were more commonly used in ANZCPR (ANZCPR: 85% vs. PERForm: 64%). ANZCPR participants had 640 mL absolute higher net prime volumes, attributed in part to higher total prime volume (1,462 mL vs. 1,217 mL) and lower adoption of retrograde autologous priming (20% vs. 81%). ANZCPR participants had higher nadir hematocrit on CPB (27 vs. 25). Minimal absolute differences existed in exposure to high arterial outflow temperatures (36.6°C vs. 37.0°C). We report substantial center and registry differences in both the type of equipment used and CPB management strategies. These findings suggest that the term "conventional bypass" may not adequately reflect real-world experiences. Instead of using this term, authors should provide key details of the CPB practices used in their patients. [ABSTRACT FROM AUTHOR]

An editorial is presented on Triple Aim program of the Institute of Healthcare Improvement (IHI) which gives emphasis on reducing per capita costs of healthcare. The Triple Aim reflects a recognition recognition that the relationship between healthcare expenditure and patient outcomes is not linear. It explores the adoption by New Zealand of the Triple Aim as a guiding framework for healthcare improvement.

Background: Simulation has been used to investigate clinical questions in anesthesia, surgery, and related disciplines, but there are few data demonstrating that results apply to clinical settings. We asked "would results of a simulation-based study justify the same principal conclusions as those of a larger clinical study?"Methods: We compared results from a randomized controlled trial in a simulated environment involving 80 cases at three centers with those from a randomized controlled trial in a clinical environment involving 1,075 cases. In both studies, we compared conventional methods of anesthetic management with the use of a multimodal system (SAFERsleep; Safer Sleep LLC, Nashville, Tennessee) designed to reduce drug administration errors. Forty anesthesiologists each managed two simulated scenarios randomized to conventional methods or the new system. We compared the rate of error in drug administration or recording for the new system versus conventional methods in this simulated randomized controlled trial with that in the clinical randomized controlled trial (primary endpoint). Six experts were asked to indicate a clinically relevant effect size.Results: In this simulated randomized controlled trial, mean (95% CI) rates of error per 100 administrations for the new system versus conventional groups were 6.0 (3.8 to 8.3) versus 11.6 (9.3 to 13.8; P = 0.001) compared with 9.1 (6.9 to 11.4) versus 11.6 (9.3 to 13.9) in the clinical randomized controlled trial (P = 0.045). A 10 to 30% change was considered clinically relevant. The mean (95% CI) difference in effect size was 27.0% (-7.6 to 61.6%).Conclusions: The results of our simulated randomized controlled trial justified the same primary conclusion as those of our larger clinical randomized controlled trial, but not a finding of equivalence in effect size.

Background: Postoperative infection is a serious problem in New Zealand and internationally with considerable human and financial costs. Also, in New Zealand, certain factors that contribute to postoperative infection are more common in Māori and Pacific populations. To date, most efforts to reduce postoperative infection have focussed on surgical aspects of care and on antibiotic prophylaxis, but recent research shows that anaesthesia providers may also have an impact on infection transmission. These providers sometimes exhibit imperfect hand hygiene and frequently transfer the blood or saliva of their patients to their work environment. In addition, intravenous medications may become contaminated whilst being drawn up and administered to patients. Working with relevant practitioners and other experts, we have developed an evidence-informed bundle to improve key aseptic practices by anaesthetists with the aim of reducing postoperative infection. The key elements of the bundle are the filtering of compatible drugs, context-relevant hand hygiene practices and enhanced maintenance of clean work surfaces.Methods: We will seek support for implementation of the bundle from senior anaesthesia and hospital leadership and departmental "champions". Anaesthetic teams and recovery room staff will be educated about the bundle and its potential benefits through presentations, written material and illustrative videos. We will implement the bundle in operating rooms where hip or knee arthroplasty or cardiac surgery procedures are undertaken in a five-site, stepped wedge, cluster randomised, quality improvement design. We will compare outcomes between approximately 5000 cases before and 5000 cases after implementation of our bundle. Outcome data will be collected from existing national and hospital databases. Our primary outcome will be days alive and out of hospital to 90 days, which is expected to reflect all serious postoperative infections. Our secondary outcome will be the rate of surgical site infection. Aseptic practice will be observed in sampled cases in each cluster before and after implementation of the bundle.Discussion: If effective, our bundle may offer a practical clinical intervention to reduce postoperative infection and its associated substantial human and financial costs.Trial Registration: Australian New Zealand Clinical Trials Registry, ACTRN12618000407291 .

This cross-sectional overview of the second 4000 incidents reported to webAIRS has findings that are very similar to the previous overview of the first 4000 incidents. The distribution of patient age, body mass index and American Society of Anesthesiologists physical status was similar, as was anaesthetist gender, grade, location and time of day of incidents. About 35% of incidents occurred during non-elective procedures (vs. 33% in the first 4000 incidents). The proportion of incidents in the various main categories was also similar, with respiratory/airway being most common, followed by cardiovascular, medication-related and medical device or equipment-related incidents. Together these categories made up about 78% of all incidents in both overviews. The immediate outcome was comparable with reports of harm in about a quarter of incidents and a similar rate of deaths (4.7% vs. 4.2%). However, the proportion of patients who had received total intravenous anaesthesia was higher (17.6% vs. 7.7%) and the proportion of patients who received combined intravenous and inhalational anaesthesia was lower (52.3% vs. 58.4%), as was the proportion receiving local anaesthesia alone (1.6% vs. 6.7%). There was a small increase in the number of incidents resulting in unplanned admission to a high dependency or intensive care unit (18.1% vs. 13.5%). It is not clear whether these differences represent trends or random observations. About 48% of incidents were considered preventable by the reporters (vs. 52% in the first 4000). These findings support continued emphasis on human and system factors to promote and improve patient safety in anaesthesia care.

Aim: Healthcare is delivered by teams, but the training of healthcare staff is commonly undertaken in professional silos. This study investigated local perspectives on the sustainability of NetworkZ, a New Zealand national simulation-based multi-disciplinary operating room team training programme., Method: Local course instructors and managers were invited to participate in semi-structured interviews. Diffusion of innovations theory was utilised to frame deductive thematic analysis of interview data., Results: Twenty-seven people participated. Interviewees described valuing NetworkZ for its multi-disciplinary orientation, in-situ delivery, scenario realism, relevance to teamwork and communication and potential for generalisability to other settings. Interviewees also identified NetworkZ as generating improvements in teamwork and crisis management. NetworkZ was described as complex, due to multidisciplinary participation and the multiple roles and skillsets of instructors needed to run simulations smoothly, making the programme resource intensive to deliver., Conclusion: NetworkZ is appreciated as a valuable and unique programme for developing important teamwork and communication skills. Its sustainability is dependent on adequate resourcing and funding., Competing Interests: All authors report grants from ANZCA, grants from ACC, during the conduct of the study; Dr Merry reports shares in Safer Sleep, grants from Fisher and Paykel, consulting fee from Fisher and Paykel, outside the submitted work.

Objective: To develop a multidimensional framework representing patients' perspectives on comfort to guide practice and quality initiatives aimed at improving patients' experiences of care., Design: Two-stage qualitative descriptive study design. Findings from a previously published synthesis of 62 studies (stage 1) informed data collection and analysis of 25 semistructured interviews (stage 2) exploring patients' perspectives of comfort in an acute care setting., Setting: Cardiac surgical unit in New Zealand., Participants: Culturally diverse patients in hospital undergoing heart surgery., Main Outcomes: A definition of comfort. The Comfort ALways Matters (CALM) framework describing factors influencing comfort., Results: Comfort is transient and multidimensional and, as defined by patients, incorporates more than the absence of pain. Factors influencing comfort were synthesised into 10 themes within four inter-related layers: patients' personal (often private) strategies; the unique role of family; staff actions and behaviours; and factors within the clinical environment., Conclusions: These findings provide new insights into what comfort means to patients, the care required to promote their comfort and the reasons for which doing so is important. We have developed a definition of comfort and the CALM framework, which can be used by healthcare leaders and clinicians to guide practice and quality initiatives aimed at maximising comfort and minimising distress. These findings appear applicable to a range of inpatient populations. A focus on comfort by individuals is crucial, but leadership will be essential for driving the changes needed to reduce unwarranted variability in care that affects comfort., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Objectives: To extend reliability of WHO Behaviourally Anchored Rating Scale (WHOBARS) to measure the quality of WHO Surgical Safety Checklist administration using generalisability theory. In this context, extending reliability refers to establishing generalisability of the tool scores across populations of teams and raters by accounting for the relevant sources of measurement errors., Design: Cross-sectional random effect measurement design assessing surgical teams by the five items on the three Checklist phases, and at three sites by two trained raters simultaneously., Setting: The data were collected in three tertiary hospitals in Auckland, New Zealand in 2016 and included 60 teams observed in 60 different cases with an equal number of teams (n=20) per site. All elective and acute cases (adults and children) involving surgery under general anaesthesia during normal working hours were eligible., Participants: The study included 243 surgical staff members, 138 (50.12%) women., Main Outcome Measure: Absolute generalisability coefficient that accounts for variance due to items, phases, sites and raters for the WHOBARS measure of the quality of WHO Surgical Safety Checklist administration., Results: The WHOBARS in its present form has demonstrated good generalisability of scores across teams and raters (G absolute=0.83). The largest source of measurement error was the interaction between the surgical team and the rater, accounting for 16.7% (95% CI 16.4 to 16.9) of the total variance in the data. Removing any items from the WHOBARS led to a decrease in the overall reliability of the instrument., Conclusions: Assessing checklist administration quality is important for promoting improvement in its use, and WHOBARS offers a reliable approach for doing this., Competing Interests: Competing interests: AFM is Chair of the New Zealand Health Quality Safety Commission., (© Author(s) (or their employer(s)) 2019.

While the WHO Surgical Safety Checklist (the Checklist) can improve patient outcomes, variable administration can erode benefits. We sought to understand and improve how operating room (OR) staff use the Checklist. Our specific aims were to: determine if OR staff can discriminate between good and poor quality of Checklist administration using a validated audit tool (WHOBARS); to determine reliability and accuracy of WHOBARS self-ratings; determine the influence of demographic variables on ratings and explore OR staff attitudes to Checklist administration., Design: Mixed methods study using WHOBARS ratings of surgical cases by OR staff and two independent observers, thematic analysis of staff interviews., Participants: OR staff in three New Zealand hospitals., Outcome Measures: Reliability of WHOBARS for self-audit; staff attitudes to Checklist administration., Results: Analysis of scores (243 participants, 2 observers, 59 cases) supported tool reliability, with 87% of WHOBARS score variance attributable to differences in Checklist administration between cases. Self-ratings were significantly higher than observer ratings, with some differences between professional groups but error variance from all raters was less than 10%. Key interview themes (33 interviewees) were: Team culture and embedding the Checklist, Information transfer and obstacles, Raising concerns and 'A tick-box exercise'. Interviewees felt the Checklist could promote teamwork and a safety culture, particularly enabling speaking up. Senior staff were of key importance in setting the appropriate tone., Conclusions: The WHOBARS tool could be useful for self-audit and quality improvement as OR staff can reliably discriminate between good and poor Checklist administration. OR staff self-ratings were lenient compared with external observers suggesting the value of external audit for benchmarking. Small differences between ratings from professional groups underpin the value of including all members of the team in scoring. We identified factors explaining staff perceptions of the Checklist that should inform quality improvement interventions., Competing Interests: Competing interests: JW has previously been employed on a project funded by the New Zealand Health Quality & Safety Commission (HQSC) to train surgical staff in the use and audit of the WHO Surgical Safety Checklist. AFM is Chair of the New Zealand HQSC Ian Civil is Chair of the Safer Surgery Program, administered by the HQSC. The HQSC is a government funded independent organisation which has led a national programme to implement the Checklist in New Zealand., (© Author(s) (or their employer(s)) 2018.

Aim: We set out to explore the question, what ethical challenges do medical students identify when asked to perform or observe a sensitive examination, given a historical background relevant to this context., Method: Thematic analysis of 21 Ethics Reports from 9 female and 12 male students., Results: Overall 14 students undertook a sensitive examination without the patient's consent; three did not carry out a sensitive examination because of a lack of consent; and two students (or their senior colleagues) gained the patient's written consent for the student to undertake the examination. One patient refused the student's request for consent to perform a digital rectal examination; and in the final case, verbal consent was given by the patient for the student to observe a bimanual examination only. Three interrelated core themes arose from thematic analysis of the research question: systemic constraints on getting consent; internal conflicts of interest; and, power and hierarchy., Conclusions: A number of senior medical students at our institution disclosed observing or performing sensitive examinations on patients without the patients' knowledge or consent., Competing Interests: Dr Merry chairs the Health Quality and Safety Commission and is Head of the School of Medicine.

Aims: The New Zealand Surgical Site Infection Improvement (SSII) Programme was established in 2013 to reduce the incidence of surgical site infections (SSI) in publicly funded hip and knee arthroplasties in New Zealand hospitals., Methods: The programme pursued a three-pronged strategy: 1. Surveillance of SSI with a nationwide system 2. Promotion of consistent adherence to evidence-based practices proven to reduce SSI 3. Monitoring and publicly reporting changed practice and outcome data., Results: Between quarter 3 2013 and quarter 4 2016 there has been a nationwide increase in compliance with all process measures: correct timing for antibiotic prophylaxis; use of the recommended antibiotic in the recommended dose and alcohol-based skin antisepsis. The SSI rate in hip and knee arthroplasties has shown a significant improvement. The nationwide median rate has fallen to 0.91% since June 2015, compared with 1.36% during the baseline period of April 2013 to March 2014 (p<0.01). This equates to approximately 55 fewer infections between August 2015 and June 2017, savings of NZD$2.2 million in avoided treatment and avoided disability-adjusted life years (DALYs) of NZD$5 million., Conclusions: The introduction of a nationwide SSI reduction programme for hip and knee arthroplasties resulted in an increase in compliance across the country with best practice that was associated with a reduction in incidence of SSI since June 2015 from the baseline period of April 2013 to March 2014, sustained to June 2017., Competing Interests: Richard Hamblin and Carl Shuker report affiliation with Health Quality & Safety Commission during the conduct of the study. Arthur Morris states that he is the Clinical Lead for the NZ Surgical Site Infection Improvement Programme. Sally Roberts is the National Clinical Lead for Health Quality and Safety Commission Infection Prevention and Control Programme. Alan Merry reports affiliation with Safer Sleep LLC, from null, outside the submitted work; and is Chair of Board of Health Quality and Safety Commission in New Zealand.

New Zealand appears to have a relatively high rate of perioperative adverse events. The Health Quality & Safety Commission's Safe Surgery NZ programme was introduced to address the rates of perioperative harm in New Zealand by promoting proper and effective use of the World Health Organization (WHO) Surgical Safety Checklist, and by encouraging use of operating room (OR) team briefings and debriefings. Venous thromboembolism prophylaxis is a key part of the checklist as deployed in New Zealand ORs, but it remains underused or variably used as well. Communication and teamwork are critical to improving patient safety and efficiency in the OR, and these interventions have demonstrated effectiveness in building and melding effective teams.

Two to five percent of those who have an inpatient surgical procedure will experience a surgical site infection (SSI). The Health Quality & Safety Commission has instituted New Zealand's first national Surgical Site Infection Improvement Programme (the SSII Programme), delivered jointly by Auckland and Canterbury District Health Boards. Through a combined package of surveillance and improvement interventions the SSII Programme aims to reduce the incidence of SSIs in New Zealand hospitals, beginning initially with hip and knee arthroplasties. Within one year of the programme starting there has been a significant nationwide improvement in the timing of surgical antimicrobial prophylaxis (p<0.0001), and the administration of the correct dose (p<0.0001). National compliance with an alcohol-based skin preparation remains high at > 95 %. In this paper we describe the purpose, background, structure and rationale of the programme and provide results to date.

To develop a national consensus statement to promote a pragmatic, appropriate and unified approach to seeking consent for medical student involvement in patient care. A modified Delphi technique was used to develop the consensus statement involving stakeholders. Feedback from consultation and each stakeholder helped to shape the final consensus statement. The consensus statement is a nationally-agreed statement concerning medical student involvement in patient care, which will be useful for medical students, health care professionals and patients.

The effective and economical measurement of the quality and safety of health and disability services in New Zealand is of signal importance. The Health Quality and Safety Commission has overseen the introduction of an architecture of interacting measures. These include quality and safety indicators, or QSIs, which are whole-system measures; quality and safety markers, or QSMs, which are targeted measures of quality and safety interventions comprising process and outcome measures in sets; and the New Zealand Atlas of Healthcare Variation, which illustrates the differences in the health care received in different regions and by different groups of patients within New Zealand.

New Zealand has one of the best value health care systems in the world, but as a proportion of GDP our spending on health care has increased every year since 1999. Further, there are issues of quality and safety in our system we must address, including rates of adverse events. The Health Quality and Safety Commission was formed in 2010 as a crown agent to influence, encourage, guide and support improvement in health care practice in New Zealand. The New Zealand Triple Aim has been defined as: improved quality, safety and experience of care; improved health and equity for all populations; and best value for public health system resources. The Commission is pursuing the Triple Aim via two fundamental objectives: doing the right thing by providing care supported by the best evidence available, focused on what matters to each individual patient, and doing the right thing right, first time, by making sure health care is safe and of the highest quality possible. Improvement efforts must be supported by robust but economical measurements. New Zealand has a strong culture of quality, so the Commission's role is to work with our colleagues to make good health care better.

Background: Effective teamwork is important for patient safety, and verbal communication underpins many dimensions of teamwork. The validity of the simulated environment would be supported if it elicited similar verbal communications to the real setting. The authors hypothesized that anesthesiologists would exhibit similar verbal communication patterns in routine operating room (OR) cases and routine simulated cases. The authors further hypothesized that anesthesiologists would exhibit different communication patterns in routine cases (real or simulated) and simulated cases involving a crisis., Methods: Key communications relevant to teamwork were coded from video recordings of anesthesiologists in the OR, routine simulation and crisis simulation and percentages were compared., Results: The authors recorded comparable videos of 20 anesthesiologists in the two simulations, and 17 of these anesthesiologists in the OR, generating 400 coded events in the OR, 683 in the routine simulation, and 1,419 in the crisis simulation. The authors found no significant differences in communication patterns in the OR and the routine simulations. The authors did find significant differences in communication patterns between the crisis simulation and both the OR and the routine simulations. Participants rated team communication as realistic and considered their communications occurred with a similar frequency in the simulations as in comparable cases in the OR., Conclusion: The similarity of teamwork-related communications elicited from anesthesiologists in simulated cases and the real setting lends support for the ecological validity of the simulation environment and its value in teamwork training. Different communication patterns and frequencies under the challenge of a crisis support the use of simulation to assess crisis management skills.

Objective: To provide a set of high-quality time-series physiologic and event data from anesthetic cases formatted in an easy-to-use structure., Materials and Methods: With ethics committee approval, data from surgical operations under general anesthesia were collected, including physiologic data, drug administrations, events, and clinicians' comments. These data were de-identified, formatted in a combined CSV/XML structure and made publicly available., Results: Two separate datasets were collected containing physiologic time-series data and time-stamped events for 34 patients. For 20 patients, the data included 400 physiologic signals collected over 20 h, 274 events, and 597 drug administrations. For 14 patients, the data included 23 physiologic signals collected over 69 h, with 286 time stamped comments., Discussion: Data reuse potentially saves significant time and financial costs. However, there are few high-quality repositories for accessible physiologic data and clinical interventions from surgical cases. De-identifying records assists with overcoming problems of privacy and storing the data in a format which is easily manipulated with computing resources facilitates access by the wider research community. It is hoped that additional high-quality data will be added. Future work includes developing tools to explore and visualize the data more efficiently, and establishing quality control measures., Conclusion: An approach to collecting and storing high-quality datasets from surgical operations under anesthesia such that they can be easily accessed by others for use in research has been demonstrated.

Aim: To compare short-term mortality and major morbidity between patients undergoing elective primary isolated CABG with bilateral internal thoracic artery (BITA) or single internal thoracic artery (SITA) grafts at Green Lane Hospital (Auckland, New Zealand)., Methods: We conducted a retrospective study of short-term outcomes in 5955 patients receiving SITA and 637 patients receiving BITA grafts between 1990 and 2004. Only patients undergoing elective primary isolated coronary artery surgery were included. The primary outcome was a composite end-point (early death, perioperative MI, reoperation for sternal wound complications or significantly prolonged hospital stay). Patients receiving BITA grafts were case-matched with patients receiving SITA grafts for confounding factors and comparison was made between perioperative outcomes in the two groups., Results: After case-matching, no statistically significant difference was found in the incidence of our primary endpoint between patients receiving BITA versus SITA grafts [odds ratio 0.84 (95% CI 0.59, 1.21)]. Furthermore, there was no difference in rates of reoperation for sternal wound complications between the two groups [odds ratio 1.00 (95% CI 0.29, 3.44)]., Conclusions: Given the potential long-term clinical advantages of BITA grafting, our results support the increased use of BITA grafts in selected patients.

There are four challenges to practicing evidence-based medicine: obtaining the evidence; evaluating the evidence; promulgating the evidence; and persuading practitioners to adopt the evidence and practice according to the evidence. The Perfusion Down Under (PDU) Collaboration addresses the first three. The fourth is more difficult, and it typically takes many years for new evidence to be adopted into widespread practice. In the case of innovations related to patient safety, evidence from randomized controlled trials is often very expensive to obtain. Other methods of evaluation may be more appropriate, but these do need to be robust and to take account of the constructs underlying the innovations and the context in which they are to be implemented. In the United States, The Institute for Healthcare Improvement (IHI) aims (among other things) to promote the adoption of best practices and effective innovations. The IHI has articulated a useful framework for doing this. Measurement is fundamental to quality improvement, and sustainable change is likely to be more readily achieved if claims are supported by credible, measurable, and clinically relevant outcome data. The PDU is well placed to support quality improvement in perfusion by providing such data.

Improving and understanding clinical practice is an appropriate goal for the perfusion community. The Perfusion Downunder Collaboration has established a multi-center perfusion focused database aimed at achieving these goals through the development of quantitative quality indicators for clinical improvement through benchmarking. Data were collected using the Perfusion Downunder Collaboration database from procedures performed in eight Australian and New Zealand cardiac centers between March 2007 and February 2011. At the Perfusion Downunder Meeting in 2010, it was agreed by consensus, to report quality indicators (QI) for glucose level, arterial outlet temperature, and pCOz management during cardiopulmonary bypass. The values chosen for each QI were: blood glucose > or =4 mmol/L and < or =10 mmol/L; arterial outlet temperature < or = 37 degrees C; and arterial blood gas pCO2 > or =35 and < or =45 mmHg. The QI data were used to derive benchmarks using the Achievable Benchmark of Care (ABC) methodology to identify the incidence of QIs at the best performing centers. Five thousand four hundred and sixty-five procedures were evaluated to derive QI and benchmark data. The incidence of the blood glucose QI ranged from 37-96% of procedures, with a benchmark value of 90%. The arterial outlet temperature QI occurred in 16-98% of procedures with the benchmark of 94%; while the arterial pCO2 QI occurred in 21-91%, with the benchmark value of 80%. We have derived QIs and benchmark calculations for the management of several key aspects of cardiopulmonary bypass to provide a platform for improving the quality of perfusion practice.

Aim: Recent studies have demonstrated a reduction in perioperative complications if a surgical safety checklist is utilised. In our institution an adaptation of the WHO Surgical Safety Checklist is administered in 3 "domains": on arrival of the patient in the operating room (Sign In); before surgical incision (Time Out) and before the patients leaves the operating room (Sign Out). Since incomplete administration or staff disengagement could diminish any safety benefit we evaluated administration of this checklist., Method: 100 adult surgical cases were observed. Compliance with administration of the Sign In, Time Out, and Sign Out domains and their component checklist items was recorded. The timing of the checklist administration, and engagement of operating room teams were also assessed., Results: The rate (per 100 cases) of the checklist domain administration was: 99 for Sign In; 94 for Time Out; and 2 for Sign Out. The mean (range) checklist item compliance was 56% (27-100%) for Sign In, 69% (33-100%) for Time Out, and 40% for Sign Out. Checklist items related to patient identity and surgical procedure were administered in 100% of Sign In administrations. Timing of the checklist administration was appropriate in over 80% of cases. Engagement by theatre teams was frequently incomplete., Conclusion: The Sign Out domain was almost always omitted, which may increase the risk of important omissions in postoperative care. Most other aspects of checklist administration could also be improved. This will require strong leadership from senior clinicians in all relevant teams.

Background: Surgery is an essential part of health care, but resources to ensure the availability of surgical services are often inadequate. We estimated the global distribution of operating theatres and quantified the availability of pulse oximetry, which is an essential monitoring device during surgery and a potential measure of operating theatre resources., Methods: We calculated ratios of the number of operating theatres to hospital beds in seven geographical regions worldwide on the basis of profiles from 769 hospitals in 92 countries that participated in WHO's safe surgery saves lives initiative. We used hospital bed figures from 190 WHO member states to estimate the number of operating theatres per 100,000 people in 21 subregions throughout the world. To estimate availability of pulse oximetry, we sent surveys to anaesthesia providers in 72 countries selected to ensure a geographically and demographically diverse sample. A predictive regression model was used to estimate the pulse oximetry need for countries that did not provide data., Findings: The estimated number of operating theatres ranged from 1·0 (95% CI 0·9-1·2) per 100,000 people in west sub-Saharan Africa to 25·1 (20·9-30·1) per 100,000 in eastern Europe. High-income subregions all averaged more than 14 per 100,000 people, whereas all low-income subregions, representing 2·2 billion people, had fewer than two theatres per 100,000. Pulse oximetry data from 54 countries suggested that around 77,700 (63,195-95,533) theatres worldwide (19·2% [15·2-23·9]) were not equipped with pulse oximeters., Interpretation: Improvements in public-health strategies and monitoring are needed to reduce disparities for more than 2 billion people without adequate access to surgical care., Funding: WHO., (Copyright © 2010 Elsevier Ltd.

A safety-orientated system of delivering parenteral anaesthetic drugs was assessed in a prospective incident monitoring study at two hospitals. Anaesthetists completed an incident form for every anaesthetic, indicating if an incident occurred. Case mix data were collected and the number of drug administrations made during procedures estimated. From February 1998 at Hospital A and from June 1999 at Hospital B, until November 2003, 74,478 anaesthetics were included, for which 59,273 incident forms were returned (a 79.6% response rate). Fewer parenteral drug errors occurred with the new system than with conventional methods (58 errors in an estimated 183,852 drug administrations (0.032%, 95% CI 0.024-0.041%) vs 268 in 550,105 (0.049%, 95% CI 0.043-0.055%) respectively, p = 0.002), a relative reduction of 35% (difference 0.017%, 95% CI 0.006-0.028%). No major adverse outcomes from these errors were reported with the new system while 11 (0.002%) were reported with conventional methods (p = 0.055). We conclude that targeted system re-design can reduce medical error.
