Background: Guidelines recommend that all nonYST-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 keywords 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. [ABSTRACT FROM AUTHOR]

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. [Copyright &y& Elsevier]

Summary 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.

Abstract: 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 18–85years 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. [Copyright &y& Elsevier]

Summary: 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.

BACKGROUND: Heart failure (HF) patients who follow the treatment regimen and attend to symptoms before they escalate are assumed to have better health-related quality of life (HRQOL) than those with poor self-care, but there are few data available to support or refute this assumption. OBJECTIVE: The objective of the study was to describe the relationship between HF self-care and HRQOL in older (?65 years old) adults with moderate to advanced HF. METHODS: Self-care was measured using the 3 scales (maintenance, management, and confidence) of the Self-care of Heart Failure Index. Scores range from 0 to 100, with higher numbers indicating better self-care. Health-related quality of life was measured with the Minnesota Living With Heart Failure Questionnaire, a 2-subscale (physical and emotional) instrument. Lower numbers on the Minnesota Living With Heart Failure Questionnaire indicate better HRQOL. Pearson correlations, independent-samples t-tests, and linear and logistic regression modeling were used in the analysis. RESULTS: In 207 adults (72.9 [SD, 6.3] years), New York Heart Association class III (82%) or IV, significant linear associations were observed between self-care confidence and total (r = -0.211; P = .002), physical (r = -0.189; P = .006), and emotional HRQOL (r = -0.201; P = .004). Patients reporting better (below median) HRQOL had higher confidence scores compared with patients reporting above-median HRQOL scores (58.8 [19.2] vs 52.8 [19.6]; P = .028). Confidence was an independent determinant of total (?s = -3.191; P = .002), physical (?s = -2.346; P = .002), and emotional (?s = -3.182; P = .002) HRQOL controlling for other Self-care of Heart Failure Index scores, age, gender, and New York Heart Association class. Each 1-point increase in confidence was associated with a decrease in the likelihood that patients had worse (above median) HRQOL scores (odds ratio, 0.980 [95% confidence interval, 0.963-0.998]) with the same controls. No significant associations were found between self-care maintenance or management and HRQOL. CONCLUSIONS: The degree of individual confidence in HF self-care is related to HRQOL, but self-reports of specific maintenance and management behaviors are not. Interventions that improve self-care confidence may be particularly important in older adults with moderate to advanced HF. [ABSTRACT FROM AUTHOR]

AIMS AND OBJECTIVES: This article analyzes the literature describing factors affecting nurses' triage of emergency department (ED) patients with potential acute coronary syndrome (ACS), with particular attention paid to gender-based differences. INTRODUCTION: Acute coronary syndrome is one of the most time-critical conditions requiring ED nurse triage. This literature review will provide examination of how triage nurses prioritize patients with possible ACS, reflecting on challenges specifically associated with evaluating women for ACS in the ED. The article presents a description of the research findings that may help improve the timely revascularization of ACS in women. METHODS: An electronic search of EBSCOhost CINAHL, Health Source Nursing Academic Edition, MEDLINE, Psychology and Behavioral Sciences Collection databases, online theses, the Cochrane Library, the Joanna Briggs Institute, and National Guideline Clearinghouse resources were used to identify all relevant scientific articles published between 1990 and 2010. Google and Google Scholar search engines were used to undertake a broader search of the World Wide Web to improve completeness of the search. This search technique was augmented by hand searching these articles' reference lists for publications missed during the primary search. RESULTS: Review of the literature suggests factors such as patient age, sex, and symptoms at ED presentation affect the accuracy of nurses' triage of ACS, particularly for women. However, research examining delays due to ED triage is scant and has predominantly been undertaken by one researcher. Little research has examined triage of ACS specifically in women. CONCLUSIONS: The literature search revealed a small number of articles describing challenges associated with nurse triage of women with ACS. Although most of this published research is North American, the themes uncovered are well supported by broader international research on acute assessment and management of women's ACS. These include the following: gender-based differences in the presentation of ACS can preclude early identification of ACS, advanced patient age often correlates with missed or delayed diagnosis of ACS, and there appears to be a general bias against managing women for ACS in parity with men's disease. RELEVANCE TO PRACTICE: Early reperfusion therapy is critical for optimal health outcomes in ACS. Triage nurses are ideally placed to minimize time to treatment for ACS. An understanding of the issues related to clinical decision making and triage allocation of women with ACS at triage is necessary to ensure appropriate treatment. [ABSTRACT FROM AUTHOR]

Abstract: Objective: The purpose of this study was to identify and describe the experiences and perceptions of nurses regarding the factors that contribute to the readmission of patients to intensive care. Methods: Twenty-one nurses participated in the study. Unstructured interviews were conducted to ascertain participants'' perceptions and experiences. Interview transcripts were analyzed using a constant comparison method to identify major conceptual categories. Results: Five main themes were identified that contributed to the readmission of patients to intensive care: premature discharge from intensive care, delayed medical care at the ward level, heavy nursing workloads, lack of adequately qualified staff, and clinically “challenging” patients who demanded a different skill set from the nurses. Conclusion: Discharging patients early from the intensive care unit when they are clinically unstable creates issues around workload and significantly challenges ward staff. It also increases the likelihood of patients being readmitted to the intensive care unit. Hospital managers need to look at ways of increasing the knowledge and skills of ward staff or identify more appropriate environments for managing these acutely ill patients.

Objective: Self-care is a key component in the management of chronic heart failure (CHF). Yet there are many barriers that interfere with a patient''s ability to undertake self-care. The primary aim of the study was to test a conceptual model of determinants of CHF self-care. Specifically, we hypothesized that cognitive function and depressive symptoms would predict CHF self-care. Methods: Fifty consecutive patients hospitalized with CHF were assessed for self-care (Self-Care of Heart Failure Index), cognitive function (Mini Mental State Exam), and depressive symptoms (Cardiac Depression Scale) during their index hospital admission. Other factors thought to influence self-care were tested in the model: age, gender, social isolation, self-care confidence, and comorbid illnesses. Multiple regression was used to test the model and to identify significant individual determinants of self-care maintenance and management. Results: The model of 7 variables explained 39% (F [7, 42] 3.80; P = .003) of the variance in self-care maintenance and 38% (F [7, 42] 3.73; P = .003) of the variance in self-care management. Only 2 variables contributed significantly to the variance in self-care maintenance: age (P < .01) and moderate-to-severe comorbidity (P < .05). Four variables contributed significantly to the variance in self-care management: gender (P < .05), moderate-to-severe comorbidity (P < .05), depression (P < .05), and self-care confidence (P < .01). When cognitive function was removed from the models, the model explained less of the variance in self-care maintenance (35%) (F [6, 43] 3.91; P = .003) and management (34%) (F [6, 43] 3.71; P = .005). Conclusion: Although cognitive function added to the model in predicting both self-care maintenance and management, it was not a significant predictor of CHF self-care compared with other modifiable and nonmodifiable factors. Depression explained only self-care management. [Copyright &y& Elsevier]

The purposes of this study were to describe heart failure patient perceptions regarding instructions received for following a low-sodium diet and the benefits, barriers, and ease and frequency of following the diet. A total of 246 patients with heart failure referred from academic medical centers in the United States and Australia participated in the study. A subset of 145 patients provided 24-hour urine samples for sodium excretion assessment. While most (80%) patients reported receiving recommendations to follow a low-sodium diet, their recall of specific instructions was poor. Although the majority (75%) reported following a low-sodium diet most or all of the time, 24-hour urine sodium excretion indicated that only 25% of patients were adherent. Patients who reported being more adherent, however, had lower urine sodium excretion levels. Attitudes regarding difficulty in and perceived benefits of following the diet were not related to sodium excretion. Data on attitudes and barriers provided guidance for strategies to improve adherence. [ABSTRACT FROM AUTHOR]

Abstract: Background: Despite the importance of the sodium-restricted diet (SRD) to heart failure (HF) management, patient adherence is poor. Little is known about gender differences in adherence or factors that affect patients'' ability to follow SRD recommendations. The purposes of this study were to determine whether there were gender differences in (1) adherence to the SRD; (2) knowledge about SRD and HF self-care; and (3) perceived barriers to following the SRD. Methods and Results: Forty-one men and 27 women completed the Heart Failure Attitudes and Barriers questionnaire that measured HF self-care, knowledge, and perceived barriers to follow an SRD. Diet adherence was measured by 24-hour urinary sodium excretion (UNa). Women were more adherent to the SRD than men as reflected by 24-hour urine excretion (2713 versus 3859 mg UNa, P = .01). Women recognized signs of excess sodium intake such as fluid buildup (P = .001) and edema (P = .01) more often than men and had better understanding of appropriate actions to take related to following an SRD. There were no gender differences in perceived barriers to follow an SRD. Conclusions: Although men and women perceived similar barriers, women were more adherent to the SRD and had greater knowledge about following an SRD. Further investigation of this phenomenon is warranted to determine if better adherence contributes to improved outcomes in women. [Copyright &y& Elsevier]

The article presents information about the National Benchmarks and Evidence-Based National Clinical Guidelines for Heart Failure Management Programs (CHF-MPs) Study. The study was conducted in Australia to determine the nature, range and effect of interventions applied by CHF-MPs. It was found that national benchmarks minimize heterogeneity among CHF-MPs.
