A safety-orientated system of delivering parenteral anaesthetic drugs was assessed in a prospective incident monitoring study at two hospitals. Anaesthetists completed an form for every anaesthetic, indicating if occurred. Case mix data were collected and the number drug administrations made during procedures estimated. From February 1998 Hospital from June 1999 B, until November 2003, 74,478 anaesthetics included, which 59,273 forms returned (a 79.6% response rate). Fewer errors occurred...
Patient safety depends on effective teamwork. The similarity of team members' mental models - or their shared understanding-regarding clinical tasks is likely to influence the effectiveness Mental have not been measured in complex, high-acuity environment operating room (OR), where professionals different backgrounds must work together achieve best surgical outcome for each patient. Therefore, we aimed explore task sequence and responsibility within multidisciplinary OR teams.We developed a...
Summary Background An acceptable systolic or mean arterial blood pressure for children 0–6 years during anesthesia is unknown. Accepted pressures reported in standard charts healthy awake may not apply to those undergoing anesthesia. Aim Our goal was define observed (BP) and heart rate (HR) 0–5 Methods Data from the electronic health record database were available a 10‐year period June 29, 2005 July 22, 2015. A simple band‐pass filter applied remove artifact physiologic time‐series data...
The consequences of even mild inadvertent perioperative hypothermia (IPH) are significant. There is a perception laparoscopic abdominal surgery less prone to cause than open surgery. However, during surgery, the peritoneal cavity insufflated with carbon dioxide, which has greater evaporative capacity ambient air. This study compared intra-operative temperature profile patients undergoing and colorectal define incidence severity hypothermia.All adult between May 2005 August 2013 were...
Background Communication of clinically relevant information between members the operating room (OR) team is critical for safe patient care. Formal communication processes, such as briefing, sign in and time out, are designed to promote this. Aims We investigated patterns OR staff simulated surgical scenarios, identify factors associated with effective sharing. focused on influence precase which we defined formal communications. Method Twenty teams six participated two scenarios during a...
Summary We implemented the World Health Organization surgical safety checklist at Auckland City Hospital from November 2007. hypothesised that would reduce postoperative mortality and increase days alive out of hospital, both measured to 90 days. compared outcomes for cohorts who had surgery during 18‐month periods before vs. after implementation. also analysed 9 years included these (July 2004–December 2013). 9475 patients in period 10,589 afterwards. 57,577 2004 2013. Mean number hospital...
The hypothesis that lunar cycles influence human behaviour, particularly incidents recorded by police or coroners, has been a topic of public and media interest around the world for decades. While connections between numerous cultural practices are well-documented, claims crime suicide statistics have not consistently supported. There recent rates in New Zealand follow cycle, correlating with Māori Maramataka calendar. Building on prior research, this study scrutinises postulated association...
Background Safe and effective healthcare is frustrated by failures in communication. Repeating back important information (read-back) thought to enhance the effectiveness of communication across many industries. However, formal protocols are uncommon teams. Aims We aimed quantify effect read-back on transfer between members a team during simulated clinical crisis. hypothesised that reading provided other would result better knowledge receiver than verbal response without or no response....
Summary The Difficult Airway Society recommends that all patients should be pre‐oxygenated before the induction of general anaesthesia, but this may not always easy or comfortable and anaesthesia often induced without full pre‐oxygenation. We tested hypothesis high‐flow nasal oxygen cannulae would easier more than facemasks for randomly allocated 199 undergoing elective surgery aged ≥ 10 years to pre‐oxygenation using either facemask. Ease comfort were assessed by anaesthetists on 10‐cm...
Objectives To measure differences at various deciles in days alive and out of hospital to 90 (DAOH ) explore its utility for identifying outliers performance among district health boards (DHBs). Methods Days mortality within surgery were extracted by linking data from the New Zealand National Minimum Data Set births deaths registry between 1 January 2011 31 December 2021 all adults undergoing acute laparotomy (AL—a relatively high-risk group), elective total hip replacement (THR—a medium...
There is a burgeoning interest in, and evidence of, quality of life burnout issues among doctors. It was hypothesized that the junior doctors in this study would experience psychosocial physiological changes over time, obtained measures indicate anomalies. In addition, it their perceptions be significantly associated with measures. A total sample 17 first year training volunteered for study. Over four time periods separated by 6 week phases, completed set inventories wore Polar RS800 Heart...
In January 2015, the US Food and Drug Administration (FDA) reported that at least 40 patients had received non-sterile intravenous fluids, resulting in associated adverse events one death. The offending products were produced for educational purposes by a company supplying growing healthcare simulation market, not intended patients. plastic bags, labelled to mimic sterile 0.9% saline solution, contaminated medication supply chain 22 locations.1 Although sequence of is yet clear, shortage...
Following general anaesthesia (GA), patients frequently experience sleep disruption and fatigue, which has been hypothesized to result at least in part by GA affecting the circadian clock. Here, we provide first comprehensive time-dependent analysis of effects commonly administered inhalational anaesthetic, isoflurane, on murine clock, analysing its (a) behavioural locomotor rhythms (b) PER2::LUC expression suprachiasmatic nuclei (SCN) mouse brain. Behavioural phase shifts elicited exposure...
Abstract Aims To examine the effects of two factors on transmission clinical information at nursing handover. These were: (i) an affective statement expressing concern about information; and (ii) verbal reference to a written summary information. Background Quality communication patient handover is inconsistent, compromising safety. Little known nuances that lead effective handovers. Furthermore, during handovers seldom evaluated using experimental research designs. Design A randomized,...
Introduction NetworkZ is a national, insurer-funded multidisciplinary simulation-based team-training programme for all New Zealand surgical teams. delivered in situ, using full-body commercial simulators integrated with bespoke models. Rolled out nationally over 4 years, the builds local capacity through instructor training and provision of simulation resources. We aim to improve patient outcomes by improving teamwork regular hospitals. Methods analysis Our primary hypothesis that will...
