Abstract
BACKGROUND There is now a rising commitment to acknowledge the role patients and families play in contributing to their safety. This review focuses on one type of involvement in safety - patient and family involvement in escalation of care for serious life-threatening conditions i.e. helping secure a step-up to urgent or emergency care - which has been receiving increasing policy and practice attention. This review was concerned with the negotiation work that patient and family members undertake across the emergency care escalation pathway, once contact has been made with healthcare staff. It includes interventions aiming to improve detection of symptoms, communication of concerns and staff response to these concerns. OBJECTIVES To assess the effects of interventions designed to increase patient and family involvement in escalation of care for acute life-threatening illness on patient and family outcomes, treatment outcomes, clinical outcomes, patient and family experience and adverse events. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL, MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP) ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform from 1 Jan 2000 to 24 August 2018. The search was updated on 21 October 2019. SELECTION CRITERIA We included randomised controlled trials (RCTs) and cluster-randomised controlled trials where the intervention focused on patients and families working with healthcare professionals to ensure care received for acute deterioration was timely and appropriate. A key criterion was to include an interactive element of rehearsal, role play, modelling, shared language, group work etc. to the intervention to help patients and families have agency in the process of escalation of care. The interventions included components such as enabling patients and families to detect changes in patients' conditions and to speak up about these changes to staff. We also included studies where the intervention included a component targeted at enabling staff response. DATA COLLECTION AND ANALYSIS Seven of the eight authors were involved in screening; two review authors independently extracted data and assessed the risk of bias of included studies, with any disagreements resolved by discussion to reach consensus. Primary outcomes included patient and family outcomes, treatment outcomes, clinical outcomes, patient and family experience and adverse events. Our advisory group (four users and four providers) ensured that the review was of relevance and could inform policy and practice. MAIN RESULTS We included nine studies involving 436,684 patients and family members and one ongoing study. The published studies focused on patients with specific conditions such as coronary artery disease, ischaemic stroke, and asthma, as well as pregnant women, inpatients on medical surgical wards, older adults and high-risk patients with a history of poor self-management. While all studies tested interventions versus usual care, for four studies the usual care group also received educational or information strategies. Seven of the interventions involved face-to-face, interactional education/coaching sessions aimed at patients/families while two provided multi-component education programmes which included components targeted at staff as well as patients/families. All of the interventions included: (1) an educational component about the acute condition and preparedness for future events such as stroke or change in fetal movements: (2) an engagement element (self-monitoring, action plans); while two additionally focused on shared language or communication skills. We had concerns about risk of bias for all but one of the included studies in respect of one or more criteria, particularly regarding blinding of participants and personnel. Our confidence in results regarding the effectiveness of interventions was moderate to low. Low-certainty evidence suggests that there may be moderate improvement in patients' knowledge of acute life-threatening conditions, danger signs, appropriate care-seeking responses, and preparedness capacity between interactional patient-facing interventions and multi-component programmes and usual care at 12 months (MD 4.20, 95% CI 2.44 to 5.97, 2 studies, 687 participants). Four studies in total assessed knowledge (3,086 participants) but we were unable to include two other studies in the pooled analysis due to differences in the way outcome measures were reported. One found no improvement in knowledge but higher symptom preparedness at 12 months. The other study found an improvement in patients' knowledge about symptoms and appropriate care-seeking responses in the intervention group at 18 months compared with usual care. Low-certainty evidence from two studies, each using a different measure, meant that we were unable to determine the effects of patient-based interventions on self-efficacy. Self-efficacy was higher in the intervention group in one study but there was no difference in the other compared with usual care. We are uncertain whether interactional patient-facing and multi-component programmes improve time from the start of patient symptoms to treatment due to low-certainty evidence for this outcome. We were unable to combine the data due to differences in outcome measures. Three studies found that arrival times or prehospital delay time was no different between groups. One found that delay time was shorter in the intervention group. Moderate-certainty evidence suggests that multi-component interventions probably have little or no impact on mortality rates. Only one study on a pregnant population was eligible for inclusion in the review, which found no difference between groups in rates of stillbirth. In terms of unintended events, we found that interactional patient-facing interventions to increase patient and family involvement in escalation of care probably have few adverse effects on patient's anxiety levels (moderate-certainty evidence). None of the studies measured or reported patient and family perceptions of involvement in escalation of care or patient and family experience of patient care. Reported outcomes related to healthcare professionals were also not reported in any studies. AUTHORS' CONCLUSIONS Our review identified that interactional patient-facing interventions and multi-component programmes (including staff) to increase patient and family involvement in escalation of care for acute life-threatening illness may improve patient and family knowledge about danger signs and care-seeking responses, and probably have few adverse effects on patient's anxiety levels when compared to usual care. Multi-component interventions probably have little impact on mortality rates. Further high-quality trials are required using multi-component interventions and a focus on relational elements of care. Cognitive and behavioural outcomes should be included at patient and staff level.

ESC Heart Fail 2018; 6:131-137. [PMID: 30353706 PMCID: PMC6351885 DOI: 10.1002/ehf2.12370] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2018] [Accepted: 09/11/2018] [Indexed: 11/16/2022] Open
Abstract
Aims Heart failure (HF) patients are taught to identify a rapid 5 lb body‐weight gain for early detection of cardiac decompensation. Few data support this common advice. The study aim was to determine whether a 5 lb weight gain in 1 week and signs and symptoms of HF increased risk for unplanned physician or emergency department (ED) visits or hospital admission in rural HF patients. Methods and results This was a secondary analysis of a randomized trial. Patients tracked body weight and HF symptoms using diaries. We included patients adherent to daily diaries >50% over 24 months (N = 119). Mean age was 69 ± 11 years; 77% (65) were male, and 67% completed diaries. A weight gain of 5 lb over 7 days was associated with a greater risk for ED visits but not hospital admission [hazard ratio (HR) 1.06, 95% confidence interval (CI) 1.04, 1.08; P < 0.0001 vs. HR 1.01, 95% CI 0.88, 1.16; P = 0.79]. Increased dyspnoea over 7 days was associated with a greater risk of ED visits and hospital admissions (HR 9.64, 95% CI 3.68, 25.22; P < 0.0001 vs. HR 5.89, 95% CI 1.73, 20.04; P = 0.01). Higher diary adherence was associated with older age, non‐sedentary behaviour, lower depression, and HF knowledge. Conclusions Heart failure patients are counselled to observe for body‐weight gain. Our data do not support that a 5 lb weight gain was associated with hospital admission. Dyspnoea was a better predictor of ED visits and hospital admissions. Daily tracking of dyspnoea symptoms may be an important adjunct to daily weight to prevent hospitalization.

Abstract
The time that elapses from the onset of symptoms of acute myocardial infarction (AMI) to treatment has a significant effect on mortality and morbidity. This study reports the effectiveness of an education and counselling intervention on knowledge, attitudes and beliefs about AMI symptoms and the appropriate response to symptoms. The intervention was tested in a randomised controlled trial of 200 people with a history of coronary heart disease (CHD). The groups were equivalent at baseline on study outcomes, clinical history and sociodemographic characteristics with the exception of more women in the intervention group (38% vs. 24%). The results of repeated measures ANOVA showed that the intervention resulted in improved knowledge of CHD, AMI symptoms and the appropriate response to symptoms that was sustained to 12 months (p=0.02). There were no differences between groups' attitudes and beliefs over time. It is concluded that a short individual teaching and counselling intervention resulted in improved knowledge of CHD, AMI symptoms and the appropriate response to symptoms in people at risk of AMI sustained to 12 months.

Abstract
BACKGROUND There is abundant research indicating poor physical, psychological, and social functioning of patients with chronic heart failure (HF), a reality that can lead to poor health-related quality of life (QoL). Little is known about the experience of rural patients with HF. METHODS AND RESULTS This study was part of a randomized clinical trial titled Rural Education to Improve Outcomes in Heart Failure (REMOTE-HF) designed to test an education and counseling intervention to improve self-care in patients with HF. We evaluated 612 rural patients. Multiple validated questionnaires were administered to assess patient perceptions of health and health literacy. Baseline factors were collected and compared with baseline QoL measures only. Patients' health-related QoL was assessed using the Minnesota Living with Heart Failure scale. The data were analyzed using a general linear model to test the association of various patient characteristics with QoL in rural patients with HF. Patients were 65.8 (+12.9) years of age. The majority were men (58.7%), married (56.4%), and had completed a high-school education (80.9%). Factors associated with reduced QoL among this population include geographic location, younger age, male sex, higher New York Heart Association class, worse HF knowledge, poorer perceived control, and symptoms of depression or anxiety. The data provided no evidence of an association between left ventricular ejection fraction and QoL. CONCLUSIONS This study of rural patients with HF confirms previously identified factors associated with perceptions of QoL. However, further study is warranted with an urban control group.

Abstract
BACKGROUND Patients' treatment-seeking delay remains a significant barrier to timely initiation of reperfusion therapy. Measurement of treatment-seeking delay is central to the large body of research that has focused on pre-hospital delay (PHD), which is primarily patient-related. This research has aimed to quantify PHD and its effects on morbidity and mortality, identify contributing factors, and evaluate interventions to reduce such delay. A definite time of symptom onset in acute coronary syndrome (ACS) is essential for determining delay, but difficult to establish. This literature review aimed to explore the variety of operational definitions of both PHD and symptom onset in published research. METHODS AND RESULTS We reviewed the English-language literature from 1998-2013 for operational definitions of PHD and symptom onset. Of 626 papers of possible interest, 175 were deemed relevant. Ninety-seven percent reported a delay time and 84% provided an operational definition of PHD. Three definitions predominated: (a) symptom onset to decision to seek help (18%); (b) symptom onset to hospital arrival (67%), (c) total delay, incorporating two or more intervals (11%). Of those that measured delay, 8% provided a definition of which symptoms triggered the start of timing. CONCLUSION We found few and variable operational definitions of PHD, despite American College of Cardiology/American Heart Association recommendations to report specific intervals. Worryingly, definitions of symptom onset, the most elusive component of PHD to establish, are uncommon. We recommend that researchers (a) report two PHD delay intervals (onset to decision to seek care, and decision to seek care to hospital arrival), and (b) develop, validate and use a definition of symptom onset. This will increase clarity and confidence in the conclusions from, and comparisons within and between studies.

Abstract
OBJECTIVE We conducted a study to identify barriers to, and factors promoting, self-care among heart failure (HF) patients with higher or lower levels of knowledge. METHOD Baseline data from 612 patients with HF enrolled in the REMOTE-HF trial were analyzed. Using median splits on the HF Knowledge Scale and the European HF Self-Care Behavior Scale, patients were divided into four groups: (a) low knowledge and good self-care, (b) low knowledge and poor self-care, (c) high knowledge and good self-care, and (d) high knowledge and poor self-care. Characteristics of the groups were compared using ANOVA, Kruskal-Wallis tests, and chi-square tests, followed by pairwise tests with Bonferroni correction. Variables significant in the univariate analyses were evaluated as predictors of self-care using hierarchical multiple linear regression. The potential moderating effect of knowledge was tested with interaction terms. RESULTS The four groups did not differ in sociodemographics or health literacy scores, but differed in New York Heart Association (NYHA) class, comorbidities, and scores on depression, anxiety, and perceived control. In post hoc pairwise tests, patients with high knowledge and poor self-care tended to have worse NYHA class, greater depression and anxiety, and lower levels of perceived control than others. In the multivariate analysis, knowledge, depressive symptoms, and perceived control were significant predictors of self-care, as was the interaction between knowledge and anxiety. CONCLUSIONS Screening and treatment of depression and anxiety is important in improving self-care among HF patients. HF management programs need to include strategies for increasing patients' perceived control over their heart disease.

Abstract
OBJECTIVES Symptoms are compared among patients with coronary artery disease (CAD) admitted to the emergency department with or without acute coronary syndrome (ACS). Sex and age are also assessed. METHODS A secondary analysis from the PROMOTION (Patient Response tO Myocardial Infarction fOllowing a Teaching Intervention Offered by Nurses) trial, an multicenter randomized controlled trial, was conducted. RESULTS Of 3522 patients with CAD, at 2 years, 565 (16%) presented to the emergency department, 234 (41%) with non-ACS and 331 (59%) with ACS. Shortness of breath (33% vs 25%, P = .028) or dizziness (11% vs 3%, P = .001) were more common in non-ACS. Chest pain (65% vs 77%, P = .002) or arm pain (9% vs 21%, P = .001) were more common in ACS. In men without ACS, dizziness was more common (11% vs 2%; P = .001). Men with ACS were more likely to have chest pain (78% vs 64%; P = .003); both men and women with ACS more often had arm pain (men, 19% vs 10% [P = .019]; women, 26% vs 13% [P = .023]). In multivariate analysis, patients with shortness of breath (odds ratio [OR], 0.617 [confidence interval [CI], 0.410-0.929]; P = .021) or dizziness (OR, .0311 [CI, 0.136-0.708]; P = .005) were more likely to have non-ACS. Patients with prior percutaneous coronary intervention (OR, 1.592 [CI, 1.087-2.332]; P = .017), chest pain (OR, 1.579 [CI, 1.051-2.375]; P = .028), or arm pain (OR, 1.751 [CI, 1.013-3.025]; P <.042) were more likely to have ACS. CONCLUSIONS In patients with CAD, shortness of breath and dizziness are more common in non-ACS, whereas prior percutaneous coronary intervention and chest or arm pain are important factors to include during ACS triage.

Abstract
BACKGROUND Health literacy has important implications for health interventions and clinical outcomes. The Shortened Test of Functional Health Literacy in Adults (S-TOFHLA) is a timed test used to assess health literacy in many clinical populations. However, its usefulness in heart failure (HF) patients, many of whom are elderly with compromised cognitive function, is unknown. We investigated the relationship between the S-TOFHLA total score at the recommended 7-minute limit and with no time limit (NTL). METHODS AND RESULTS We enrolled 612 rural-dwelling adults with HF (mean age 66.0 ± 13.0 years, 58.8% male). Characteristics affecting health literacy were identified by multiple regression. Percentage of correct scores improved from 71% to 86% (mean percent change 15.1 ± 18.1%) between the 7-minute and NTL scores. Twenty-seven percent of patients improved ≥1 literacy level with NTL scores (P < .001). Demographic variables explained 24.2% and 11.1% of the variance in % correct scores in the 7-minute and the NTL scores, respectively. Female gender, younger age, higher education, and higher income were related to higher scores. CONCLUSION Patients with HF may be inaccurately categorized as having low or marginal health literacy when the S-TOFHLA time limits are enforced. New ways to assess health literacy in older adults are needed.

Abstract
BACKGROUND Patients with chronic heart failure (HF) and their partners face many challenges associated with heart disease. High social support in a close relationship has been found to improve survival in patients with HF. However, caring for a patient with HF may have negative effects on the health-related quality of life (HRQOL) of the partner responsible for the care. The main focus in health care is still on improving patients' HRQOL, but the awareness of partners' and families' role and situation is increasing. Therefore, further studies are needed to clarify these issues and the importance of partners in relation to HRQOL of patients with HF. OBJECTIVES To describe and compare HRQOL, quality-adjusted life-year (QALY) weights, symptoms of depression, and perceived control and knowledge in patients with chronic HF and their partners and to compare HRQOL and QALY weights in the partners with an age- and sex-matched group. METHODS Data were collected from 135 patient-partner dyads at 2 Swedish hospitals. Data on the reference group were collected from the same region. RESULTS Patients had lower HRQOL in all dimensions (P<.001) except in the mental health domain and lower QALY weights compared with their partners (P<.001). Mental health scores were lower in partners compared with the age- and sex-matched references (P<.001). All other HRQOL scores and the QALY weights were comparable between partners and reference group. Patients had more depressive symptoms than did their partners (P<.001). There was no difference in the level of perceived control or knowledge about chronic HF between patients and partners. CONCLUSIONS Our findings confirm that partners of patients with chronic HF have markedly diminished mental health. Interventions focusing on education and psychosocial support may potentially promote mental health in partners and enhance their ability to support the patient.

Abstract
BACKGROUND The statistical power of cluster randomized trials depends on two sample size components, the number of clusters per group and the numbers of individuals within clusters (cluster size). Variable cluster sizes are common and this variation alone may have significant impact on study power. Previous approaches have taken this into account by either adjusting total sample size using a designated design effect or adjusting the number of clusters according to an assessment of the relative efficiency of unequal versus equal cluster sizes. PURPOSE This article defines a relative efficiency of unequal versus equal cluster sizes using noncentrality parameters, investigates properties of this measure, and proposes an approach for adjusting the required sample size accordingly. METHODS We focus on comparing two groups with normally distributed outcomes using t-test, and use the noncentrality parameter to define the relative efficiency of unequal versus equal cluster sizes and show that statistical power depends only on this parameter for a given number of clusters. We calculate the sample size required for an unequal cluster sizes trial to have the same power as one with equal cluster sizes. RESULTS Relative efficiency based on the noncentrality parameter is straightforward to calculate and easy to interpret. It connects the required mean cluster size directly to the required sample size with equal cluster sizes. Consequently, our approach first determines the sample size requirements with equal cluster sizes for a pre-specified study power and then calculates the required mean cluster size while keeping the number of clusters unchanged. Our approach allows adjustment in mean cluster size alone or simultaneous adjustment in mean cluster size and number of clusters, and is a flexible alternative to and a useful complement to existing methods. Comparison indicated that we have defined a relative efficiency that is greater than the relative efficiency in the literature under some conditions. LIMITATIONS Our measure of relative efficiency might be less than the measure in the literature under some conditions, underestimating the relative efficiency. CONCLUSIONS The relative efficiency of unequal versus equal cluster sizes defined using the noncentrality parameter suggests a sample size approach that is a flexible alternative and a useful complement to existing methods.

Abstract
AIMS To describe the levels and identify independent predictors of caregiver burden in partners of patients with heart failure. BACKGROUND Care and support from a partner are important for the well-being of patients with heart failure and may potentially delay disease progression. However, caregiving may be associated with burden and stress and it is therefore important to understand which factors that influence caregiver burden. Theoretical models of caregiving describe the concept of burden as an outcome variable, including decreased well-being and health. METHODS Data for this descriptive cross-sectional study were collected between January 2005 and September 2008. The dependent variable consisted of the Caregiver Burden Scale total score index. Socio-demographic and clinical characteristics, health-related quality of life, symptoms of depression, perceived control, and knowledge on heart failure were included in a regression analysis to determine independent predictors of caregiver burden. RESULTS The 135 partners had a mean-age of 69 years and 75% were females. Caregiver burden was perceived as medium in 30% of the partners. The patients' Physical Component Score of SF-36 (p<0.001), partners' Mental Component Score of SF-36 (p<0.001) and perceived control (p<0.01) accounted for 39% of the variance in caregiver burden. CONCLUSION Caregiver burden was lower when the mental health of the partner and the physical health of the patient were better and the partner experienced higher control over the heart disease. A partner-centered approach to educate and support partners of patients with heart failure is essential to improve the life situation for patient-partner dyads.

Abstract
BACKGROUND Improving cardiac related knowledge to further healthy lifestyles is the best preventive strategy against coronary heart diseases (CHD). Previous studies revealed a critical shortage in all-around cardiac related knowledge, plus an overall shortage in adopting healthy lifestyle behaviors. AIMS To evaluate the effectiveness of an education, counseling and behavioral skill-building program in Jordanian working adults' knowledge, attitudes, and beliefs about CHD and adoption of a healthy lifestyle. METHODS A non-equivalent quasi-experimental design was used to evaluate the effectiveness of the intervention program that is based on Pender's Health Promotion Model. The Response Questionnaire and HPLP-II were used to measure subjects' knowledge, attitudes, beliefs and adoption of healthy lifestyle. RESULTS One hundred six subjects completed the posttest questionnaires. Experimental group showed significantly better cardiac related knowledge, better scores for attitudes, and better scores for the health responsibility, nutritional behaviors, interpersonal relationships and total HPLP-II score. Subject's beliefs, physical activity, spiritual growth and stress management were not improved significantly. Men had better scores in beliefs and women had better scores for health responsibility. CONCLUSION Individual commitment to healthier lifestyles should be encouraged, and researchers have to design and apply more specific interventions that are directed toward improving factors that are not significantly improved through traditional programs.

Abstract
BACKGROUND The timely and accurate identification of symptoms of acute coronary syndrome (ACS) is a challenge for patients and clinicians. It is unknown whether response times and clinical outcomes differ with specific symptoms. We sought to identify which ACS symptoms are related-symptom clusters-and to determine if sample characteristics, response times, and outcomes differ among symptom cluster groups. METHODS In a multisite randomized clinical trial, 3522 patients with known cardiovascular disease were followed up for 2 years. During follow-up, 331 (11%) had a confirmed ACS event. In this group, 8 presenting symptoms were analyzed using cluster analysis. Differences in symptom cluster group characteristics, delay times, and outcomes were examined. RESULTS The sample was predominantly male (67%), older (mean 67.8, S.D. 11.6 years), and white (90%). Four symptom clusters were identified: Classic ACS characterized by chest pain; Pain Symptoms (neck, throat, jaw, back, shoulder, arm pain); Stress Symptoms (shortness of breath, sweating, nausea, indigestion, dread, anxiety); and Diffuse Symptoms, with a low frequency of most symptoms. Those in the Diffuse Symptoms cluster tended to be older (P = .08) and the Pain Symptoms group was most likely to have a history of angina (P = .01). After adjusting for differences, the Diffuse Symptoms cluster demonstrated higher mortality at 2 years (17%) than the other 3 clusters (2%-5%, P < .001), although prehospital delay time did not differ significantly. CONCLUSION Most ACS symptoms occur in groups or clusters. Uncharacteristic symptom patterns may delay diagnosis and treatment by clinicians even when patients seek care rapidly. Knowledge of common symptom patterns may facilitate rapid identification of ACS.

Abstract
BACKGROUND AND RESEARCH OBJECTIVE Several heart failure (HF) knowledge tools have been developed and tested over the past decade; however, they vary in content, format, psychometric properties, and availability. This article details the development, psychometric testing, and revision of the Atlanta Heart Failure Knowledge Test (A-HFKT) as a standardized instrument for both the research and clinical settings. PARTICIPANTS AND METHODS Development and psychometric testing of the A-HFKT were undertaken with 116 New York Heart Association (NYHA) class II and III community-dwelling HF patients and their family members (FMs) participating in a family intervention study. Internal consistency, reliability, and content validity were examined. Construct validity was assessed by correlating education level, literacy, dietary sodium ingestion, medication adherence, and healthcare utilization with knowledge. RESULTS Content validity ratings on relevance and clarity ranged from 0.55 to 1.0, with 81% of the items rated from 0.88 to 1.0. Cronbach alpha values were .84 for patients, .75 for FMs, and .73 for combined results. Construct validity testing revealed a small but significant correlation between higher patient and FM knowledge on sodium restriction questions and lower ingested sodium, r = -0.17, P = .05 and r = -0.19, P = .04, respectively, and between patient knowledge and number of days that medications were taken correctly (diuretics: r = 0.173, P < .05, and angiotensin-converting enzyme: r = 0.223, P = .01). Finally, patients seeking emergency care or requiring hospitalization in the 4 months before study entry were found to have significantly lower FM knowledge using both t test and logistic regression modeling. CONCLUSIONS The A-HFKT was revised using the content and construct validity data and is available for use with HF patients and FMs. The construct validity testing indicates that patient knowledge has a significant relationship to aspects of self-care. Furthermore, family knowledge may influence patient adherence with sodium restriction and healthcare utilization behavior.

Abstract
Duration of delay in seeking medical care in persons with symptoms of evolving acute myocardial infarction (AMI) is of current interest given the time-dependent benefits associated with early use of coronary reperfusion approaches. The objectives of this multinational study were to describe geographic variation in the extent of and factors associated with prehospital delay in patients enrolled in the GRACE study. Data were collected from 44,695 patients hospitalized with an acute coronary syndrome in 14 countries from 2000 to 2006. The regions under study included Argentina and Brazil (n = 8,203), United States/Canada (n = 12,810), Europe (n = 19,354), and Australia/New Zealand (n = 4,328). Patients with ST-segment elevation AMI, non-ST-segment elevation AMI, and unstable angina comprised the study population. There were marked geographic differences in extent of prehospital delay in patients with ST-segment elevation AMI and those with non-ST-segment elevation AMI/unstable angina. In patients with ST-segment elevation AMI, the shortest duration of prehospital delay was observed in patients from Australia/New Zealand (median 2.2 hours), whereas patients from Argentina and Brazil delayed the longest (median 4.0 hours). Median duration of prehospital delay was shortest (2.5 hours) in patients with ST-segment elevation AMI, whereas patients with non-ST-segment elevation AMI/unstable angina showed considerably longer prehospital delay (3.1 hours). Several demographic and clinical characteristics were associated with prolonged delay overall and in the different geographic locations under study. In conclusion, results of this large multinational registry provided insights into contemporary patterns of care-seeking behavior in patients with acute coronary disease.

Abstract
Despite numerous studies on women's cardiac health throughout the past decade, the number of female deaths caused by cardiovascular disease still rises and remains the leading cause of death in women in most areas of the world. Novel studies have demonstrated that cardiovascular disease, and more specifically coronary artery disease presentations in women, are different than those in men. In addition, pathology and pathophysiology of the disease present significant gender differences, which leads to difficulties concerning diagnosis, treatment and outcome of the female population. The reason for this disparity is all steps for female cardiovascular disease evaluation, treatment and prevention are not well elucidated; and an area for future research. This review brings together the most recent studies published in the field of coronary artery disease in women and points out new directions for future investigation on some of the important issues.

Abstract
BACKGROUND Self-monitoring by heart failure (HF) patients of worsening symptoms caused by fluid overload is a cornerstone of HF care. Disease management has improved outcomes in HF; however, these resource-intensive programs are limited to urban centers and are generally unavailable in rural or limited health care access areas. This pilot study sought to determine whether a simplified education program focused on a single component of disease management (symptom recognition and management of fluid weight) could improve knowledge, patient-reported self-care behavior, and HF severity in a rural setting. METHODS This randomized clinical trial enrolled 36 rural HF patients into an intervention or control group. The intervention group received a simplified education program with a follow-up phone call focusing on symptom management delivered by a non-cardiac-trained nurse. Patient knowledge, self-care behaviors, and HF severity (B-natriuretic peptide [BNP]) were measured at enrollment and at 3 months. RESULTS The sample was primarily white men and married with a mean age of 71 years and ejection fraction of 47%. There were no differences between groups in knowledge, self-care behaviors and BNP at baseline; however, knowledge and self-care behavior related to daily weights improved significantly at 3 months in the intervention group (P = .01 and .03, respectively). Although the changes in mean BNP at 3 months were in the hypothesized direction, the difference between the 2 groups was not significant. CONCLUSIONS A simplified education program designed for use in resource scarce settings improves knowledge and patient-reported self-care behaviors. These findings are important in providing care to patients with HF in limited access settings but should be studied for longer periods in more heterogeneous populations.

Abstract
The resurgence of interest in the effect of neighborhood contexts on health outcomes, motivated by advances in social epidemiology, multilevel theories and sophisticated statistical models, too often fails to confront the enormous methodological problems associated with causal inference. This paper employs the counterfactual causal framework to illuminate fundamental obstacles in the identification, explanation, and usefulness of multilevel neighborhood effect studies. We show that identifying useful independent neighborhood effect parameters, as currently conceptualized with observational data, to be impossible. Along with the development of a dependency-based methodology and theories of social interaction, randomized community trials are advocated as a superior research strategy, one that may help social epidemiology answer the causal questions necessary for remediating disparities and otherwise improving the public's health.

Abstract
OBJECTIVE We examined differences in transport times for patients with chest pain who used private transportation compared with patients who used emergency medical services (EMS) to reach definitive medical care. METHODS This was a retrospective cohort study with data used from the Rapid Early Action for Coronary Treatment (REACT) trial conducted in 20 US cities. Elapsed time to care was examined through the use of (1) decision to seek care to initial care (emergency department [ED] arrival versus EMS arrival on scene [n=1209]); (2) decision to ED arrival (for both groups [n=2388]); (3) time to thrombolytic therapy once admitted to the ED (for both groups [n=309]); and (4) decision to seek care to thrombolytic therapy (n=276). Elapsed travel times were ranked within Zip Codes and submitted to a nested analysis of variance model to determine if elapsed times were different between modes of transport. RESULTS Private transportation (35 minutes) resulted in faster ED arrival than using EMS (39 minutes, P =.0014). However, if one considers EMS treatment to be initial care, calling 9-1-1 (6 minutes) resulted in much quicker care than patients using private transportation to the ED (32 minutes, P <.001). Transport by EMS resulted in a shorter elapsed time to thrombolytic administration compared with patients using private transportation when considering ED "door-to-needle" time (32 vs 49 minutes, respectively [P <.001]) or time from decision to seek care until administration of thrombolytic therapy (75 vs 92 minutes, respectively, [P =.042]). CONCLUSIONS Although private transportation results in a faster trip to the ED, quicker care is obtained with the use of EMS.

Abstract
Cardiac disease is the most common cause of death in the United States, and sudden cardiac arrest frequently claims the lives of men and women during their most productive years. It is believed that much better survival rates can be achieved for victims of cardiac arrest through optimizing the "chain of survival" as described by the American Heart Association. The relative and incremental benefit of full prehospital ACLS over basic life support and defibrillation is unproven, however. This is an important issue in this era of cost containment. Some of the ongoing studies including the OPALS study may clarify the cost effectiveness and relative efficacy of rapid defibrillation and full ACLS programs for victims of prehospital cardiac arrest [6].

Abstract
Our primary study aim was to examine extent of, and factors associated with, delay in seeking medical care in a large multinational registry of patients with acute myocardial infarction (AMI) and unstable angina pectoris. A secondary goal was to examine the relation between duration of prehospital delay and receipt and timing of coronary reperfusion strategies. Investigators from 14 countries are participating in the Global Registry of Acute Coronary Events (GRACE) project. The study sample consisted of 3,693 patients with ST-segment elevation AMI, 2,935 with non-ST-segment elevation AMI, and 3,954 patients with unstable angina hospitalized between 1999 and 2001. The average and median delay times were longest in patients with non-ST-segment elevation AMI (6.1 and 3.0 hours, respectively) followed by patients with unstable angina (5.6 and 3.0 hours) and those with ST-segment elevation AMI (4.7 and 2.3 hours). Approximately 41% of patients with ST-segment elevation AMI presented to the 94 study hospitals within 2 hours of the onset of acute coronary symptoms; this compared with approximately one third of patients with non-ST-segment elevation AMI and unstable angina. Several demographic and clinical characteristics were associated with prehospital delay. In patients with ST-segment elevation AMI, duration of prehospital delay was inversely related to the receipt of thrombolytic therapy, but was inconsistently related to the use of percutaneous coronary interventions. The results of this study demonstrate that a large proportion of patients continue to exhibit prolonged delay in seeking medical care after the onset of acute coronary symptoms and remain in need of targeted educational efforts to reduce extent of delay.

Abstract
The optimal treatment of patients with AIS depends on a well-run, integrated system of care involving patients and teams of health care professionals. It begins with patient education and extends to a method for accessing an efficient and effective EMS system. Medics must be well equipped and well trained to evaluate and begin initial treatment during prompt transport to an appropriate hospital. The role of out-of-hospital 12-lead ECGs and thrombolysis is reviewed and may be appropriate for some EMS systems. The initial evaluation and treatment in the ED goes on simultaneously and is a dynamic process. Prompt treatment with oxygen, nitroglycerin, morphine, and aspirin is indicated. Initial risk stratification is based on the first ECG, cardiac biomarkers, and the clinical history and physical exam. Disposition and further evaluation is individualized according to the initial work-up and risk assessment.

Abstract
OBJECTIVE The purpose of this study was to compare the clinical manifestations of first-time acute myocardial infarction (AMI) in 3 age groups of men and women who presented to the emergency departments of 3 acute tertiary care hospitals. DESIGN An exploratory, descriptive design was used, and there were 2 phases to the project. Phase 1 was a retrospective chart audit of a systematic random sample of patient charts, and phase 2 included a structured interview of a prospective random sample of emergency and intensive care unit nurses and physicians. The data were collected by using a chart audit tool and a semistructured interview, respectively. SETTING The study took place at a western Canada university affiliated with acute tertiary care centres. SAMPLE A systematic random sample of 153 (105 men and 48 women) patient charts were audited from the health records departments of 3 acute care hospitals. All of the patients had experienced a first-time AMI. In addition, a random sample of emergency/intensive care unit nurses (n = 60) and physicians (n = 18) was interviewed. RESULTS The results indicate that a statistically significant number of the oldest (75 years or older) male patients present with atypical manifestations of AMI compared with the men in the younger age groups (P =.005). The same trend was not noted for female patients. The results of the study are limited with respect to the small number of women in each age category. Caution must therefore be exercised in generalizing the results to the target population of women with AMI. The atypical manifestations are described. The results of the interviews revealed that many clinicians do not look for different clinical manifestations when assessing older patients. CONCLUSIONS It is essential that nurses and physicians accurately assess patients with AMI, especially patients in the older age groups who may be presenting atypically. It is also important that professional and nonprofessional public health education initiatives include information regarding both typical and atypical presentation of AMI, particularly in the older patient.

Abstract
Personal risk perceptions of acute myocardial infarction (AMI) affect people's preventive health behaviors as well as their beliefs during a heart attack episode. The authors investigated factors that are associated with personal risk perceptions of having an AMI. A random-digit-dial survey was conducted among 1294 respondents, aged 18 years or older, in 20 communities across the nation as part of the Rapid Early Action for Coronary Treatment (REACT) trial. Results of two mixed-model linear regression analyses suggested that worse perceived general health, more risk factors, and greater knowledge were associated with greater perception of AMI risk. The results also showed that women who answered, incorrectly, that heart disease is not the most common cause of death for women in the United States reported significantly lower risk perceptions than women who answered this question correctly. The findings in this study suggest that interventions need to target specific misconceptions regarding AMI risk.

Abstract
Cardiovascular disease is the leading cause of death for women in the United States. Despite recent advances in treatment options for acute myocardial infarction (AMI), there has not been similar progress in decreasing the time between symptom onset and the decision to seek medical help (labeled "decision delay") and therefore availability of such treatments. Women delay longer than men before seeking help for symptoms of AMI, yet few studies have analyzed decision delay by gender. Factors studied to date do not adequately explain the differences in decision delay among women or between women and men with AMI. Additional research is needed to guide interventions to limit decision delay in women at risk for AMI. Until then, clinicians should use existing general guidelines to assist women at risk of AMI to avoid decision delay.

Abstract
BACKGROUND Patient delay in seeking health care for heart attack symptoms is a continuuing problem in the United States. METHODS Investigators conducted focus groups (N = 34; 207 participants) in major U.S. regions (NE, NW, SE, SW, MW) as formative evaluation to develop a multi-center randomized community trial (the REACT Project). Target groups included adults with previous heart attacks, those at higher risk for heart attack, and bystanders to heart attacks. There were also subgroups reflecting gender and ethnicity (African-American, Hispanic-American, White). FINDINGS Patients, bystanders, and those at higher risk expected heart attack symptoms to present as often portrayed in the movies, that is, as sharp, crushing chest pain rather than the more common onset of initially ambiguous but gradually increasing discomfort. Patients and those at higher risk also unrealistically judge their personal risk as low, understand little about the benefits of rapid action, are generally unaware of the benefits of using EMS/9-1-1 over alternative transport, and appear to need the "permission" of health care providers or family to act. Moreover, participants reported rarely discussing heart attack symptoms and appropriate responses in advance with health care providers, spouses, or family members. Women often described heart attack as a "male problem," an important aspect of their underestimation of personal risk. African-American participants were more likely to describe negative feelings about EMS/9-1-1, particularly whether they would be transported to their hospital of choice. CONCLUSIONS Interventions to reduce patient delay need to address expectations about heart attack symptoms, educate about benefits and appropriate actions, and provide legitimacy for taking specific health care-seeking actions. In addition, strategy development must emphasize the role of health care providers in legitimizing the need and importance of taking rapid action in the first place.

Abstract
BACKGROUND Reperfusion therapy for acute myocardial infarction (AMI) is a time-dependent intervention that can reduce infarct-related morbidity and mortality. Out-of-hospital patient delay from symptom onset until emergency department (ED) presentation may reduce the expected benefit of reperfusion therapy. OBJECTIVE To determine the impact of a community educational intervention to reduce patient delay time on the use of reperfusion therapy for AMI. METHODS This was a randomized, controlled community-based trial to enhance patient recognition of AMI symptoms and encourage early ED presentation with resultant increased reperfusion therapy rates for AMI. The study took place in 44 hospitals in 20 pair-matched communities in five U.S. geographic regions. Eligible study subjects were non-institutionalized patients without chest injury (aged > or =30 years) who were admitted to participating hospitals and who received a hospital discharge diagnosis of AMI (ICD 410); n = 4,885. For outcome assessment, patients were excluded if they were without survival data (n = 402), enrolled in thrombolytic trials (n = 61), receiving reperfusion therapy >12 hours after ED arrival (n = 628), or missing symptom onset or reperfusion times (n = 781). The applied intervention was an educational program targeting community organizations and the general public, high-risk patients, and health professionals in target communities. The primary outcome was a change in the proportion of AMI patients receiving early reperfusion therapy (i.e., within one hour of ED arrival or within six hours of symptom onset). Trends in reperfusion therapy rates were determined after adjustment for patient demographics, presenting blood pressure, cardiac history, and insurance status. Four-month baseline was compared with the 18-month intervention period. RESULTS Of 3,013 selected AMI patients, 40% received reperfusion therapy. Eighteen percent received therapy within one hour of ED arrival (46% of treated patients), and 32% within six hours of symptom onset (80% of treated patients). No significant difference in the trends in reperfusion therapy rates was attributable to the intervention, although increases in early reperfusion therapy rates were noted during the first six months of the intervention. A significant association of early reperfusion therapy use with ambulance use was identified. CONCLUSIONS Community-wide educational efforts to enhance patient response to AMI symptoms may not translate into sustained changes in reperfusion practices. However, an increased odds for early reperfusion therapy use during the initiation of the intervention and the association of early therapy with ambulance use suggest that reperfusion therapy rates can be enhanced.

Abstract
This study investigated how patients' emergency department experience was related to their intention to delay action in response to future symptoms of acute myocardial infarction. A sample of 426 persons admitted to the emergency department with a chief complaint of chest pain and released from the emergency department were contacted by telephone. Patients were queried about their affective response to the emergency department experience, their satisfaction with emergency department staff communication, their intention to delay prompt action for acute myocardial infarction symptoms in the future, the influence of others in the decision to seek care, and medical and demographic status. The results of a mixed model linear regression analysis showed that the less education patients had (p = 0.007), the less sure they felt that going to the emergency department had been "the right thing to do" (p = 0.004), and the greater the degree of embarrassment (p = 0.0001), the greater was the intention to delay action for future symptoms of acute myocardial infarction. The results also showed that those patients who were prompted by health professionals to go to the emergency department were less likely to report intentions to delay for future symptoms (p = 0.036). It is important that emergency department staff reassure chest pain patients who are sent home that they did the right thing by coming to the emergency department for their symptoms. Providers need to be particularly sensitive to feelings of embarrassment.

Abstract
BACKGROUND Empirical evidence suggests that people value emergency medical services (EMS) but that they may not use the service when experiencing chest pain. This study evaluates this phenomenon and the factors associated with the failure to use EMS during a potential cardiac event. METHODS AND RESULTS Baseline data were gathered from a randomized, controlled community trial (REACT) that was conducted in 20 US communities. A random-digit-dial survey documented bystander intentions to use EMS for cardiac symptoms in each community. An emergency department surveillance system documented the mode of transport among chest pain patients in each community and collected ancillary data, including situational factors surrounding the chest pain event. Logistic regression identified factors associated with failure to use EMS. A total of 962 community members responded to the phone survey, and data were collected on 875 chest pain emergency department arrivals. The mean proportion of community members intending to use EMS during a witnessed cardiac event was 89%; the mean proportion of patients observed using the service was 23%, with significant geographic differences (range, 10% to 48% use). After controlling for covariates, non-EMS users were more likely to try antacids/aspirin and call a doctor and were less likely to subscribe to (or participate in) an EMS prepayment plan. CONCLUSIONS The results of this study indicate that indecision, self-treatment, physician contact, and financial concerns may undermine a chest pain patient's intention to use EMS.

Abstract
BACKGROUND There are few data on possible age and sex differences in presentation of symptoms for patients with acute coronary disease. OBJECTIVE To investigate demographic differences in presentation of symptoms at the time of hospital presentation for acute myocardial infarction (AMI) and unstable angina. METHODS The medical records of patients who presented with chest pain and who also had diagnoses of AMI (n = 889) or unstable angina (n = 893) on discharge from 43 hospitals were reviewed as part of data collection activities of the Rapid Early Action for Coronary Treatment trial based in 10 pair-matched communities throughout the USA. RESULTS Dyspnea (49%), arm pain (46%), sweating (35%), and nausea (33%) were commonly reported by men and women of all ages in addition to the presenting complaint of chest pain. After we had controlled for various characteristics through regression modeling, older persons with AMI were significantly less likely than were younger persons to complain of arm pain and sweating, and men were significantly less likely to report vomiting than were women. Among persons with unstable angina, arm pain and sweating were reported significantly less often by elderly patients. Nausea and back, neck, and jaw pain were more common complaints of women. CONCLUSIONS Results of this study suggest that there are differences between symptoms at presentation of men and women, and those in various age groups, hospitalized with acute coronary disease. Clinicians should be aware of these differences when diagnosing and managing patients suspected to have coronary heart disease.

Abstract
The potential for reducing cardiovascular disease mortality rates lies both in prevention and treatment. The earlier treatment is administered, the greater the benefit. Thus, duration of time from onset of symptoms of acute myocardial infarction to administration of treatment is important. One major factor contributing to failure to receive efficacious therapy is the delay time from acute myocardial infarction (AMI) symptom onset to hospital arrival. This paper examines the relationship of several factors with regard to intentions to seek care promptly for symptoms of AMI. A random-digit dialed telephone survey (n = 1294) was conducted in 20 communities located in 10 states. People who said they would wait until they were very sure that symptoms were a heart attack were older, reported their insurance did not pay for ambulance services, and reported less confidence in knowing signs and symptoms in themselves. When acknowledging symptoms of a heart attack, African-Americans and people with more than a high school education reported intention to act quickly. No measures of personal health history, nor interaction with primary care physicians or cardiologists were significantly related to intention to act fast. The study confirms the importance of attribution and perceived self-confidence in symptom recognition in care seeking. The lack of significant role of health history (i.e. those with chronic conditions or risk factors) and clinician contact highlights missed opportunities for health care providers to educate and encourage patients about their risk and appropriate action.

Abstract
Rapid Early Action for Coronary Treatment (REACT) was a multisite trial testing a community intervention to reduce the delay between onset of symptoms of acute myocardial infarction (MI) and patients' arrival at a hospital emergency department. The study employed a group-randomized trial design, with ten communities randomized from within matched pairs to each of two conditions. REACT also employed continuous data collection, based on surveillance of heart attack patients in community emergency departments. They analysed their data by comparing the mean slope for delay time in the ten intervention communities to the mean slope estimated in the ten control communities. Because no estimates of slope variation were available a priori, REACT was sized using approximations based on more traditional designs. In this paper, we present the slope and residual error variances as estimated from the REACT data and examine their influence on the power of the trial post hoc. We also examine the power of the trial as it would have been given a more traditional pretest-post-test design with analysis via a comparison of the net difference in condition means pretest vs post-test.

Abstract
BACKGROUND The use of thrombolytic therapy for patients with myocardial infarction has been limited by patient delay in seeking care. We sought to characterize prehospital delay in patients hospitalized for evaluation of heart attack symptoms. METHODS AND RESULTS The Rapid Early Action for Coronary Treatment (REACT) is a multicenter, randomized community trial designed to reduce patient delay. At baseline, data were abstracted from the medical records of 3783 patients hospitalized for evaluation of heart attack symptoms in 20 communities. The median prehospital delay was 2.0 hours; 25% of patients delayed longer than 5.2 hours. In a multivariable analysis, delay time was longer among non-Hispanic blacks than among non-Hispanic whites, longer at older ages, longer among Medicaid-only recipients and shorter among Medicare recipients than among privately insured patients, and shorter among patients who used an ambulance. CONCLUSIONS The observed pattern of differences is consistent with the contention that demographic, cultural, and/or socioeconomic barriers exist that impede rapid care seeking.

Abstract
To inform intervention development in a multisite randomized community trial, the Rapid Early Action for Coronary Treatment (REACT) project formative research was undertaken for the purpose of investigating the knowledge, beliefs, perceptions, and usual practice of health care professionals. A total of 24 key informant interviews of cardiologists and emergency physicians and 15 focus groups (91 participants) were conducted in five major geographic regions: Northeast, Northwest, Southeast, Southwest, and Midwest. Transcript analyses revealed that clinicians are somewhat unaware of the empirical evidence related to the problem of patient delay, are concerned about the practice constraints they face, and would benefit from concrete suggestions about how to improve patient education and encourage fast action. Findings provide guidance for selection of educational strategies and messages for health providers as well as patients and the public.

Abstract
OBJECTIVE To determine the consistency of responses to a standardized 2-part "key" question (Key-Q) about acute symptom onset in patients presenting with chest pain when measured using alternative questions (Qs) about symptom perception and decisions to seek treatment. METHODS A structured patient interview was performed at 3 university teaching hospitals and 1 community hospital. Convenience samples of adult patients presenting to these EDs with chest pain were asked specific questions related to their symptoms and recognition of illness. Information obtained included the 2-part Key-Q: "What are the symptoms that brought you here today?" and "When did those symptoms start?" The alternative Qs (in order of use) were as follows: Q1 = "When did your very first symptom or sensation begin?"; Q2 = "When did your symptoms lead you to think something was wrong or that you were ill?"; Q3 = "When did your symptoms become serious enough for you to seek medical care?"; and Q4 = "When did you actually call 9-1-1/emergency medical services (EMS) or go to the hospital?" The documented ED arrival time, demographic variables, and whether the patient arrived by ambulance were obtained from the medical record. Patients also were queried regarding potential barriers to seeking medical care and their cardiac risk factors. RESULTS Of the 135 patients surveyed, 9 were unsure of the date and time of symptom onset. For the 126 patients with analyzable data, the mean (+/- SD) patient age was 62 +/- 16 years, and 59% were male. The general sequence of events reported from acute symptom onset until hospital care was Q1/Key-Q-->Q2-->Q3-->Q4-->ED arrival. The median differences and interquartile ranges (IQRs) in minutes between Q times and the Key-Q response were: Q1 = 0 (0-0); Q2 = 30 (0-210); Q3 = 140 (30-720); Q4 = 265 (90-1,215); and ED arrival = 340 (120-1,230). The interval from the Key-Q response until calling 9-1-1/EMS or going to the hospital was shorter for those who used an ambulance and for those who did not consult a physician first. The interval from the Key-Q response until considering symptoms to be serious was shorter for those with a family history of heart disease, but longer for non-white patients. CONCLUSION The Key-Q elicited a response recalled near the time of first symptoms and generally before the patient had concluded something was "wrong or that he or she was ill." Measurement of the out-of-hospital delay in chest pain patients using the Key-Q appears promising.

Abstract
The National Heart Attack Alert Program (NHAAP) was launched by the National Heart, Lung, and Blood Institute in 1991 with the goal of reducing morbidity and mortality from acute myocardial infarction (AMI) through the rapid identification and treatment of individuals with symptoms and signs of an AMI. To achieve this goal, the NHAAP established objectives for each of three phases of action where treatment delays can occur: in the hospital, the prehospital setting, and the patient/bystander arena. The NHAAP initially directed its educational efforts toward emergency department professionals. Recommendations for reducing delays in emergency department identification of patients presenting with heart attack symptoms were developed by a working group convened in late 1991. These recommendations were published in February 1994 in a peer-reviewed journal reaching more than 17,000 emergency physicians. The NHAAP worked in a partnership with its coordinating committee, representing 40 health professional, voluntary, and government organizations, to extend the reach of the report's recommendations to their members. Strategies for promoting the emergency department recommendations included publication of excerpts in newsletters and journals of the medical, nursing, and prehospital provider organizations represented on the NHAAP Coordinating Committee, and through symposia at annual meetings. Industry assisted with dissemination efforts and with implementing a continuous quality improvement program based on the paper's recommendations. The NHAAP also developed, with the Joint Committee on Accreditation of Health Care Organizations, a time-to-treatment indicator for thrombolytic therapy to be incorporated into their Indicator Measurement System (IMSystem). To track achievement of the objectives related to the Hospital Action Phase, national data sources for emergency department management of patients with AMI were evaluated at the 5-year point of the NHAAP. Data from a national registry showed that the median time from presentation at the emergency department to receiving thrombolytic therapy declined by about one third between 1992 and the last half of 1995. The percentage of all Medicare patients receiving thrombolytic therapy within the recommended 30 minutes after emergency department arrival nearly doubled between 1992 and 1995. Based on these and other results presented at the 5-year juncture of the program, the NHAAP Coordinating Committee assessed progress and identified new areas of focus for the next 5 years. Improvements in emergency departments' ability to identify and treat AMI patients progressed during the first 5 years of the NHAAP, when the program was highlighting this as a priority. This model is continuing to be used to address delays in the Prehospital Action Phase. Further research from a National Heart, Lung, and Blood Institute (NHLBI) community intervention trial will guide the program in its plans for full-scale public education to address the Patient/Bystander Recognition and Action Phase.
