Depression screening and referral in cardiac wards: A 12-month patient trajectory.

BACKGROUND: Depression is common among patients with coronary heart disease (CHD) and has a major impact on their quality of life, morbidity and mortality. AIM: The aim of this study was to map the 12-month psychosocial outcomes of patients with CHD who were screened positive for depression in an acute cardiac ward. METHODS: A prospective cohort study was conducted of the psychosocial trajectory (depression, anxiety, wellbeing, social support, mental health service access) of 212 patients with CHD who were screened for depression after being admitted to acute cardiac wards of a major metropolitan hospital. Outcomes were assessed before hospital discharge and at one, three, six and 12 months post-discharge. RESULTS: Linear mixed models identified that those patients screened at 'moderate to high' risk of depression at baseline had higher levels of depression ( F(1,173)=53.93, p<0.0001) and anxiety ( F(1,180)=67.01, p<0.001), and lower levels of wellbeing ( F(1,186)=42.47, p<0.001) and social support ( F(1,177)=25.40, p<0.0001), compared to those at 'no to low' risk of depression. Levels of depression and wellbeing remained fairly constant over the 12-month trajectory. Surgical and medical treatment groups were of similar psychological composition over the 12-month period. CONCLUSIONS: These findings attest to the effectiveness and predictive validity of a simple nurse-administered screening tool designed to identify depression in hospital patients with CHD and also indicate that a screening and referral tool alone is not sufficient to achieve optimal disease management. A collaborative care model involving family members and integrated pathways to primary care is recommended.

Systematic Review and Meta-analyses Investigating Whether Risk Stratification Explains Lower Rates of Coronary Angiography Among Women With Non-ST-Segment Elevation Acute Coronary Syndrome.

BACKGROUND: Guidelines recommend that all non-ST-segment elevation acute coronary syndrome (NSTEACS) patients with high-risk features receive a coronary angiogram. We hypothesised that the widely reported gender disparity in the use of angiography might be the result of women more frequently being stratified into the lower-risk category. OBJECTIVES: The aim of the study was to review studies reporting risk stratification of NSTEACS patients by gender, compare risk profiles, and assess impact on use of coronary angiography. METHODS: PubMed, Scopus, and EMBASE databases were searched on June 17, 2014, using MeSH terms/subheadings and/or key words with no further limits. The search revealed 1230 articles, of which 25 met our objective. RESULTS: Among the 28 risk-stratified populations described in the 25 articles, women were more likely to be stratified as high-risk in 13 studies; men were more likely to be stratified as high-risk in 3 studies. After meta-analyses, women had a 23% higher odds of being stratified as high-risk than did men (P = .001). Lower-risk patients were more likely to receive an angiogram in 15 study populations. CONCLUSIONS: Contrary to our hypothesis, this review showed that women with NSTEACS are more likely than men to be considered high-risk when stratified using a range of risk assessment methods. Lower rates of angiography in women form part of a broader treatment-risk paradox, which may involve gender bias in the selection of patients for invasive therapy.

Gender difference in the use of coronary interventions for patients with acute coronary syndrome: Experience from a major metropolitan hospital in Melbourne, Australia.

BACKGROUND: Literature suggests an ongoing gender disparity in the use of coronary angiography and subsequent interventions among patients with acute coronary syndrome (ACS). OBJECTIVES: The study aimed to examine gender differences in the use of coronary interventions amongst patients with acute coronary syndrome (ACS) admitted to a major metropolitan hospital in Melbourne during the period 2009-2012. METHODS: We undertook a retrospective analysis of a hospital database of 2096 ACS patients. ACS included unstable angina (UA), ST-segment-elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI). RESULTS: The mean age of the patients was 64.3 years and 624 (30%) were women. Half of them were diagnosed as NSTEMI, 23% as STEMI and 25% as UA. Compared to men, women were older at admission, less likely to be diagnosed with STEMI and less likely to smoke. No gender difference was observed for severe co-morbidities or use of coronary angiography. Women diagnosed with STEMI were 39% less likely to receive an angioplasty stent (adjusted odds ratio 0.61, 95% confidence intervals 0.39-0.96) and 66% less likely to receive grafts (adjusted OR 0.34, 95% CIs 0.13-0.93). Women diagnosed with NSTEMI were 44% less likely to receive grafts (adjusted OR 0.56, 95% CIs 0.37-0.83). Younger women aged 35-49 years were less likely to receive an angioplasty stent, and older women >50 years were less likely to receive grafts. CONCLUSIONS: Adherence to guideline based treatment will help to ensure knowledge translation from guideline to practice. Further research investigating symptom presentation, use of non-invasive tests and medical management of ACS by gender may further explain gender difference for coronary interventions.

Exploring Aboriginal patients' experiences of cardiac care at a major metropolitan hospital in Melbourne.

Objectives The aim of the present study was to explore Aboriginal patients' lived experiences of cardiac care at a major metropolitan hospital in Melbourne. Methods The study was a qualitative study involving in-depth interviews with a purposive sample of 10 Aboriginal patients who had been treated in the cardiology unit at the study hospital during 2012-13. A phenomenological approach was used to analyse the data. Results Eight themes emerged from the data, each concerning various aspects of participants' experiences: 'dislike of hospitals', 'system failures', 'engagement with hospital staff', 'experiences of racism', 'health literacy and information needs', 'self-identifying as Aboriginal', 'family involvement in care' and 'going home and difficulties adapting'. Most participants had positive experiences of the cardiac care, but hospitalisation was often challenging because of a sense of dislocation and disorientation. The stress of hospitalisation was greatly mediated by positive engagements with staff, but at times exacerbated by system failures or negative experiences. Conclusion Cardiac crises are stressful and hospital stays were particularly disorienting for Aboriginal people dislocated from their home land and community. What is known about the topic? Aboriginal people have higher mortality rates due to cardiovascular diseases compared with other Australians. Along with different factors contributing to the life expectancy gap, Aboriginal people also face significant barriers in the use of the healthcare system. What does this paper add? Aboriginal patients' lived experience of cardiac care at a major metropolitan hospital in Melbourne is explored in this paper. Different issues were revealed during their interaction with the hospital staff and the hospital system in conjunction with their cultural aspect of patient care. What are the implications for practitioners? Positive interactions with staff, ongoing support from family and community, culturally appropriate cardiac rehabilitation programs can improve the cardiac care experiences of Aboriginal patients.

Impact of comorbidities and gender on the use of coronary interventions in patients with high-risk non-ST-segment elevation acute coronary syndrome.

OBJECTIVES: To determine the impact of gender and comorbidity on use of coronary interventions in patients diagnosed with high-risk non-ST-segment acute coronary syndrome (NSTEACS). BACKGROUND: Guidelines recommend the use of coronary angiography for all patients diagnosed with NSTEACS with high-risk features, except in the presence of severe comorbidities. However, little is understood about the relationship between gender, comorbidity, and the use of coronary interventions. METHODS: Retrospective analyses of the Victorian Admitted Episodes Data Set (VAED) including all patients diagnosed with NSTEACS with high-risk features on their first admission for ACS between June 2007 and July 2009. Hierarchical logistic regression models and correspondence analyses were used to understand the relationship between gender, comorbidities, and the use of coronary interventions. RESULTS: Out of 16,771 NSTEACS patients with high-risk features, 6,338 (38%) were female. Females were older than males (aged ≥75: 62% vs 39%, p < 0.001) and more likely to have multiple comorbidities (≥2: 66% vs 59%, p < 0.001). After adjusting for potential confounders, females were more likely to receive no coronary intervention than males with a similar number of comorbid conditions (no comorbidities: OR 1.62, 95% CI 1.28-2.05; 1 comorbidity: OR 1.67, 95% CI 1.44-1.93; 2 comorbidities: OR 1.93, 95% CI 1.66-2.23; ≥3 comorbidities: OR 1.42, 95% CI 1.27-1.60). CONCLUSIONS: Lower rates of coronary intervention in females persisted after adjusting for number of comorbidities which suggests that gender may bias decisions regarding referral for coronary intervention in high-risk NSTEACS independent of other factors.

Gender Differences in Presentation, Coronary Intervention, and Outcomes of 28,985 Acute Coronary Syndrome Patients in Victoria, Australia.

BACKGROUND: Differences in demographics, presenting characteristics, and treatment of heart disease in women may contribute to adverse outcomes. The purpose of this paper was to describe gender differences in the epidemiology, treatment, and outcomes of all admissions for acute coronary syndrome (ACS) in Victoria that occurred between June 2007 and July 2009. METHODS: We undertook a retrospective cohort study of all patients admitted to Victorian hospitals with a first time diagnosis of ACS. Use of angiograms, percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG), and adverse outcomes (death and/or unplanned readmission) were compared by gender and hierarchical logistic regression models were used to account for confounding variables. RESULTS: Of a total of 28,985 ACS patients, 10,455 (36%) were women. Compared with men, women were older (aged ≥75 years: 54% vs 31%; p < .001), more likely to present with multiple comorbidities (>1 comorbidity: 53% vs 46%; p < .001), and more likely to be diagnosed with non-ST-segment elevation ACS (86% vs 80%; p < .001). Women were less likely to receive coronary interventions (angiogram: adjusted odds ratio [aOR], 0.71; 95% CI, 0.66-0.75; PCI: aOR, 0.73; 95% CI, 0.66-0.80; CABG: aOR, 0.58; 95% CI, 0.53-0.64). Adverse outcomes were similar in women and men after accounting for confounding variables. CONCLUSIONS: Our results show that women in Victoria were less likely to receive coronary interventions after an admission for ACS. Clinicians should be wary of inherent gender bias in decisions to refer patients for angiography.

Is There any Gender Difference for Smoking Persistence or Relapse Following Diagnosis or Hospitalization for Coronary Heart Disease? Evidence From a Systematic Review and Meta-Analysis.

INTRODUCTION: Persistent smoking in patients diagnosed with coronary heart disease (CHD) has a significant effect on morbidity and mortality. Although there has been considerable debate around gender differences in smoking cessation, conclusive evidence on how gender impacts rates of smoking cessation and/or relapse following CHD diagnosis is lacking. AIMS AND METHODS: Our aim was to test the hypothesis that female smokers with CHD were more likely to persist in smoking or relapse post-diagnosis or hospitalization than male smokers. We searched PubMed and Web of Science databases for studies published in the last 10 years. Meta-analyses were conducted using a random effects model. RESULTS: Sixteen studies met the inclusion criteria. The aggregated sample size was 36 591, 20 617 (56%) were smokers of which 2564 (12%) were female. Meta-analyses of eight studies where smoking prevalence could be measured, showed that females were less likely to be smokers at baseline than males (OR = 0.30, 95% CI = 0.13 to 0.70). Overall, one in two (47%) smokers persisted in smoking/relapsed following a diagnosis or hospitalization for CHD; but there was no gender difference in the rate of persistent smoking/relapse (OR = 1.07, 95% CI = 0.95 to 1.21). CONCLUSIONS: Female smokers with CHD were relatively uncommon in the included study populations. However, the rate of persistent smoking/relapse was high in both female and male smokers following a diagnosis or hospitalization for CHD. Therefore similar, sustained smoking cessation efforts are warranted for both genders. IMPLICATIONS: There was no gender difference for persistent smoking/relapse following a diagnosis or hospitalization for CHD, but the rate was high in both female and male smokers. Therefore, similar, sustained smoking cessation efforts are warranted for both genders.

E-cigarettes and smoking cessation: evidence from a systematic review and meta-analysis.

BACKGROUND: E-cigarettes are currently being debated regarding their possible role in smoking cessation and as they are becoming increasingly popular, the research to date requires investigation. OBJECTIVES: To investigate whether the use of e-cigarettes is associated with smoking cessation or reduction, and whether there is any difference in efficacy of e-cigarettes with and without nicotine on smoking cessation. DATA SOURCES: A systematic review of articles with no limit on publication date was conducted by searching PubMed, Web of Knowledge and Scopus databases. METHODS: Published studies, those reported smoking abstinence or reduction in cigarette consumption after the use of e-cigarettes, were included. Studies were systematically reviewed, and meta-analyses were conducted using Mantel-Haenszel fixed-effect and random-effects models. Degree of heterogeneity among studies and quality of the selected studies were evaluated. RESULTS: Six studies were included involving 7,551 participants. Meta-analyses included 1,242 participants who had complete data on smoking cessation. Nicotine filled e-cigarettes were more effective for cessation than those without nicotine (pooled Risk Ratio 2.29, 95%CI 1.05-4.97). Amongst 1,242 smokers, 224 (18%) reported smoking cessation after using nicotine-enriched e-cigarettes for a minimum period of six months. Use of such e-cigarettes was positively associated with smoking cessation with a pooled Effect Size of 0.20 (95%CI 0.11-0.28). Use of e-cigarettes was also associated with a reduction in the number of cigarettes used. LIMITATIONS: Included studies were heterogeneous, due to different study designs and gender variation. Whilst we were able to comment on the efficacy of nicotine vs. non-nicotine e-cigarettes for smoking cessation, we were unable to comment on the efficacy of e-cigarettes vs. other interventions for cessation, given the lack of comparator groups in the studies included in this meta-analysis. CONCLUSIONS: Use of e-cigarettes is associated with smoking cessation and reduction. More randomised controlled trials are needed to assess effectiveness against other cessation methods.

Gender difference in treatment and mortality of patients with ST-segment elevation myocardial infarction admitted to Victorian public hospitals: a retrospective database study.

BACKGROUND: Death from acute coronary syndrome (ACS) is avoidable with early reperfusion therapy, however, evidence suggests inequity in women's ACS treatment within a number of international healthcare systems, when compared to men's. Research indicates mortality rates are higher in some age groups of women when compared to men for the sub-group of ACS known as ST-segment elevation myocardial infarction (STEMI). OBJECTIVE: To determine whether patient sex was associated with patterns of reperfusion treatment variation or increased inhospital mortality in patients with STEMI. METHODS: We undertook retrospective analyses on a government database for patients admitted to Victorian public hospitals with STEMI. Patients were categorised into two age groups: 18-64 and 65-84 years (inclusive), to determine whether patient sex and these age groups influenced treatment from 2005 to 2008 and mortality from 2005 to 2010. RESULTS: Both younger and older women received less frequent angioplasty with stent and more often received no reperfusion treatment than men in corresponding younger and older age groups (p=0.006 and p<0.001, respectively). Overall, women in both age groups were more likely to die inhospital than men from equivalent age groups with STEMI (p<0.001, both groups). CONCLUSIONS: Proportionately, both younger and older women received less interventional reperfusion therapy for STEMI than their male cohorts, and died more often during admission than men. Further research needs to be undertaken to verify the findings and causes, and guide future research to ensure application of evidence to treatment in patients with STEMI.

Assessment of an established dialysis nurse practitioner model of care using mixed methods research.

AIMS AND OBJECTIVES: To assess a dialysis nurse practitioner (NP) model of care by examining satisfaction, quality of life (QOL) and clinical outcomes of haemodialysis patients and explore experiences of dialysis nurses. DESIGN: Mixed methods. METHODS: Database analyses of dialysis indices amongst a sample (n = 45) of haemodialysis patients; a survey (n = 27) examining patient experience, satisfaction and QOL; and in-depth interviews with a sample (n = 10) of nurses. RESULTS: Nurses commended the NP role, with five themes emerging: "managing and co-ordinating", "streamlining and alleviating", "developing capability", "supporting innovation and quality" and "connecting rurally". Patients' average age was 66 years and 71% were male. Patients' satisfaction with the care they received was rated 3.5/4 or higher across seven parameters and the average QOL score was 7.9/10. CONCLUSION: The NP model of care is effective in enhancing patient care within a collaborative framework. The challenge is to sustain, and enhance the model, through mentorship programs for potential candidates.

Implementing a working together model for Aboriginal patients with acute coronary syndrome: an Aboriginal Hospital Liaison Officer and a specialist cardiac nurse working together to improve hospital care.

Acute coronary syndrome (ACS) contributes to the disparity in life expectancy between Aboriginal and non-Aboriginal Australians. Improving hospital care for Aboriginal patients has been identified as a means of addressing this disparity. This project developed and implemented a working together model of care, comprising an Aboriginal Hospital Liaison Officer and a specialist cardiac nurse, providing care coordination specifically directed at improving attendance at cardiac rehabilitation services for Aboriginal Australians in a large metropolitan hospital in Melbourne. A quality improvement framework using a retrospective case notes audit evaluated Aboriginal patients' admissions to hospital and identified low attendance rates at cardiac rehabilitation services. A working together model of care coordination by an Aboriginal Hospital Liaison Officer and a specialist cardiac nurse was implemented to improve cardiac rehabilitation attendance in Aboriginal patients admitted with ACS to the cardiac wards of the hospital. A retrospective medical records audit showed that there were 68 Aboriginal patients admitted to the cardiac wards with ACS from 1 July 2008 to 30 June 2011. A referral to cardiac rehabilitation was recorded for 42% of these. During the implementation of the model of care, 13 of 15 patients (86%) received a referral to cardiac rehabilitation and eight of the 13 (62%) attended. Implementation of the working together model demonstrated improved referral to and attendance at cardiac rehabilitation services, thereby, has potential to prevent complications and mortality. WHAT IS KNOWN ABOUT THE TOPIC?: Aboriginal Australians experience disparities in access to recommended care for acute coronary syndrome. This may contribute to the life expectancy gap between Aboriginal and non-Aboriginal Australians. WHAT DOES THIS PAPER ADD?: This paper describes a model of care involving an Aboriginal Hospital Liaisons Officer and a specialist cardiac nurse working together to improve hospital care and attendance at cardiac rehabilitation services for Aboriginal Australians with acute coronary syndrome. WHAT ARE THE IMPLICATIONS FOR PRACTITIONERS?: The working together model of care could be implemented across mainstream health services where Aboriginal people attend for specialist care.

Factors associated with post-intensive care unit adverse events: a clinical validation study.

BACKGROUND: Many patients discharged from intensive care units (ICU) have complex care needs, placing them at risk of an adverse event in a ward environment. Currently, there is limited understanding of factors associated with these events in the post-intensive care population. A recent study explored intensive care liaison nurses' opinions on factors associated with these events; 25 factors were identified, highlighting the multifaceted nature of post-intensive care adverse events. AIM: This study aimed to clinically validate 25 factors intensive care liaison nurses believe are associated with post-intensive care adverse events, to determine the factors' relevance and importance to clinical practice. DESIGN: Prospective, clinical validation study. METHOD: Data were prospectively collected on a convenience sample of 52 patients at 4 tertiary referral hospitals in an Australian capital city. All patients had experienced an adverse event after intensive care discharge. RESULTS: Each of the 25 factors contributed to adverse events in at least 6 patients. The factors associated with the most adverse events were those that related to the patient such as illness severity and co-morbidities. CONCLUSION: Clinical care and research should focus on modifiable factors in care processes to reduce the risk of future adverse events in post-intensive care patients. RELEVANCE TO CLINICAL PRACTICE: Many patients are at risk of post-ICU adverse events due to the contribution of non-modifiable factors. However, by focusing on modifiable factors in care processes, the risk of post-ICU adverse events may be reduced.

A review of sedation scales for the cardiac catheterization laboratory.

PURPOSE: Sedation scales have the potential to facilitate effective procedural sedation and analgesia in the cardiac catheterization laboratory (CCL). For this potential to become realized, a scale that is suitable for use in the CCL either needs to be identified or developed. DESIGN: A structured review strategy was applied. METHODS: To identify sedation scales, a review of Medline and CINHAL was conducted. FINDINGS: One sedation scale for the CCL, the North American Society for Pacing and Electrophysiology Sedation Scale, and 15 intensive care unit (ICU) scales met the inclusion and exclusion criteria. Analysis of the scale's item structures and psychometric properties was then performed. CONCLUSION: None of these scales were deemed suitable for use in the CCL. As such, further research is required to develop a new scale. The new scale should consist of more than one item to make it more effective for tracking the patient's response to medications. Specific tests required to conduct a rigorous evaluation of the new scale's psychometric properties are outlined in this article.

Smoking behavior among patients and staff: a snapshot from a major metropolitan hospital in Melbourne, Australia.

BACKGROUND: A cross-sectional study was conducted to provide a snapshot of smoking behavior among staff and patients at a major metropolitan hospital in Melbourne. METHODS: Patients and staff were surveyed using a questionnaire exploring demographics, nicotine dependence (Fagerstrom test), readiness to quit, and preference for smoking cessation options. RESULTS: A total of 1496 people were screened within 2 hours; 1,301 participated (1,100 staff, 199 patients). Mean age was 42 years, 68% were female. There were 113 (9%) current smokers and 326 (25%) ex-smokers. Seven percent of the staff were current smokers compared with 19% of the patients. The Fagerstrom test showed that 47% of patients who smoked were moderately nicotine dependent compared with 21% of staff. A third of the staff who smoked did not anticipate health problems related to smoking. Most patients (79%) who smoked disagreed that their current health problems were related to smoking. Although more than half of the current smokers preferred pharmacotherapy, one in two of them did not prefer behavior counseling; with consistent results among staff and patients. Multivariate analyses showed that patients were three times more likely (odds ratio 3.0, 95% confidence interval 1.9-4.7) to smoke than staff. CONCLUSION: This study reports lower prevalence of smoking among hospital staff compared with national data. It also indicates an under-appreciation of health effects of smoking, and a preference not to use conventional methods of quitting.

Electronic cigarettes: patterns of use, health effects, use in smoking cessation and regulatory issues.

BACKGROUND: Electronic cigarettes (e-cigarettes) are battery-powered devices that vaporize a liquid solution to deliver a dose of inhaled nicotine to the user. There is ongoing debate regarding their regulation. OBJECTIVES: This comprehensive narrative review aimed to discuss key issues including usage patterns, health effects, efficacy in smoking cessation and regulatory concerns with a view to informing future regulation and research agendas. METHODS: PubMed, Scopus and Web of Science databases were searched using the terms (electronic cigarettes OR e-cigarettes) for articles in English, relevant to humans and published during January 2009-January 2014. RESULTS: The literature search revealed 37 relevant articles. Findings suggest that e-cigarettes are mostly used by middle-aged current smokers, particularly males, to help them for quitting or for recreation. E-cigarettes contain very low levels of multiple toxic substances such as formaldehyde and acrolein, but these levels are many times lower than those found in cigarettes. They were found to have effectiveness in aiding smoking cessation to a limited degree. Debate continues regarding regulating their use for cessation versus heavy restrictions to control recreational use on the basis that it perpetuates nicotine addiction. CONCLUSIONS: The cytotoxicity and long term health effects of e-cigarettes are unknown. Nevertheless the e-cigarette market continues to expand, largely driven by middle-aged smokers who claim to be using e-cigarettes in an attempt to reduce or quit smoking. E-cigarettes may have some potential as smoking cessation aids and, in the researchers' view, should therefore be subject to further research and regulation similar to other nicotine replacement therapies.

The process and utility of classification and regression tree methodology in nursing research.

AIM: This paper presents a discussion of classification and regression tree analysis and its utility in nursing research. BACKGROUND: Classification and regression tree analysis is an exploratory research method used to illustrate associations between variables not suited to traditional regression analysis. Complex interactions are demonstrated between covariates and variables of interest in inverted tree diagrams. DESIGN: Discussion paper. DATA SOURCES: English language literature was sourced from eBooks, Medline Complete and CINAHL Plus databases, Google and Google Scholar, hard copy research texts and retrieved reference lists for terms including classification and regression tree* and derivatives and recursive partitioning from 1984-2013. DISCUSSION: Classification and regression tree analysis is an important method used to identify previously unknown patterns amongst data. Whilst there are several reasons to embrace this method as a means of exploratory quantitative research, issues regarding quality of data as well as the usefulness and validity of the findings should be considered. IMPLICATIONS FOR NURSING RESEARCH: Classification and regression tree analysis is a valuable tool to guide nurses to reduce gaps in the application of evidence to practice. With the ever-expanding availability of data, it is important that nurses understand the utility and limitations of the research method. CONCLUSION: Classification and regression tree analysis is an easily interpreted method for modelling interactions between health-related variables that would otherwise remain obscured. Knowledge is presented graphically, providing insightful understanding of complex and hierarchical relationships in an accessible and useful way to nursing and other health professions.

Effect of patient sex on triage for ischaemic heart disease and treatment onset times: A retrospective analysis of Australian emergency department data.

UNLABELLED: Time between emergency department (ED) presentation and treatment onset is an important, but little-researched phase within the revascularization process for ischaemic heart disease (IHD). OBJECTIVE: To determine if sex influences triage score allocation and treatment onset for patients with IHD in the ED. METHODS: Retrospective data for patients 18-85 years presenting to EDs from 2005 to 2010 for acute myocardial infarction (AMI), unstable and stable angina, and chest pain were analysed collectively and separately for AMI. RESULTS: Proportionately more men (61% of males) were triaged correctly for AMI than women (51.4% of females; P<0.001). Across all triage categories, average treatment time was faster for men than women with AMI (P<0.001). When incorrectly triaged for AMI, treatment time for men was faster than for women (P=0.04). When correctly triaged for AMI, there was no difference in mean treatment time between men and women (P=0.538). CONCLUSIONS: Substantial undertriage of AMI occurred for both sexes, but was worse in women. Incorrect triage led to prolonged treatment times for AMI, with women's treatment delays longer than men's. When triaged correctly, both sexes were treated early for AMI, emphasising the need for all patients to be accurately triaged for this time-sensitive disease.

Intensive care readmission: a contemporary review of the literature.

ICU readmissions are a commonly used quality measure but despite decades of research, these adverse events continue to occur. Of particular concern is that readmitted patients have much worse prognoses than those not readmitted. In recent years new clinical service roles have evolved to assist ward staff with the care of acutely ill patients, such as those discharged from ICU. Given the recent emergence of these service roles, a review of contemporary ICU readmission studies was warranted to determine their impact on this adverse event. Reviewed studies indicated the incidence of readmissions and outcomes of these patients have changed little in recent years. Few studies mentioned whether clinical service roles existed to support ward staff caring for patients recently discharged from ICU. Future research needs to focus on identifying modifiable factors in care processes to reduce the incidence and outcomes of this adverse event and to determine how clinical service roles can best help prevent its occurrence.

Factors associated with delayed treatment onset for acute myocardial infarction in Victorian emergency departments: a regression tree analysis.

BACKGROUND: Minimising time to treatment onset for acute myocardial infarction (AMI) in the emergency department (ED) is essential, yet little is understood about the interactions between variables affecting it. The aim of this study was to develop a regression tree model explicating the influence of patient and non-patient factors on the time taken to commence treatment for patients with AMI in Victorian EDs. METHODS: A regression tree model for variables impacting time to treatment was developed on retrospective data for patients aged 18-85 years with AMI treated in Victorian EDs from 2005 to 2010 (n=21,080). Data were partitioned into three subsets, with a complexity parameter set at 0.0005. RESULTS: Four variables emerged in the final regression tree model: triage score; mode of arrival; area of residence; and patient sex. The variable most influencing time to treatment onset for AMI was triage category. For undertriaged patients, treatment time patterns were affected by arrival mode, residential location and their sex, significantly extending delays to treatment onset. CONCLUSIONS: Interactions between specific variables influenced whether patients with AMI were treated with equity in Victorian EDs, resulting in previously unidentified evidence-practice gaps and an improved understanding of which patient groups were vulnerable to delayed treatment for AMI.
