Abstract
BACKGROUND Prehospital delay, the time of symptom onset until the time of hospital arrival, for patients with symptoms of acute coronary syndrome (ACS) is frequently used to determine the course of care. Total ischemic time (time for symptom onset until the time of first coronary artery balloon inflation) is another criterion for quality of care for patients experiencing ST-segment elevation myocardial infarction. However, obtaining the exact time of symptom onset, the starting point of both time intervals, is challenging. Currently 2 methods are used to obtain the time of symptom onset: abstraction of data from the medical record and structured interviews done after the acute event. It is not clear whether these methods are equally accurate. PURPOSE Using identified search terms, PubMed and the Cumulative Index to Nursing and Allied Health Literature were searched for articles published from 1990 to 2014 to identify studies that examined agreement between the 2 data sources to determine prehospital delay in patients with ACS. CONCLUSIONS Five studies examined the accuracy and/or agreement of prehospital delay by medical record review and structured patient interviews. In these studies, the percentage of missing/incomplete data in the medical record was higher compared with interviews (14%-40% vs 12%-13%). Three of the 4 studies that compared the 2 data sources reported more than 50% disagreement, with the time of symptom onset starting sooner when obtained by interview compared with the time recorded in their medical record at hospital presentation. CLINICAL IMPLICATIONS There is a need for a consistent, reliable method to assess the time of symptom onset in patients with ACS. To ensure the accuracy of data collected for the medical record, training of emergency and critical care clinicians should (1) emphasize the importance of assessing symptoms broadly, (2) provide tips on interviewing techniques to help patients pinpoint the time of symptom onset, and (3) instill the value of complete documentation.

Congruence of the Medical Record and Subject Interview on Time of Symptom Onset in Patients Diagnosed With Acute Coronary Syndrome. Dimens Crit Care Nurs 2016; 35:332-338.

Abstract
BACKGROUND Past research has shown discrepancies between the time of symptom onset for patients with acute coronary syndrome (ACS) as documented in the medical record (MR) and patients' recall of the time assessed through subject interviews done later by researchers. PURPOSE The aim of this study is to determine if there were differences between the time of symptom onset documented in the MR and subject interview taking into consideration sex, age group, and recall period for patients admitted to the emergency department for symptoms suggestive of ACS. METHODS A secondary analysis was conducted on data from the PROMOTION (Patient Response to Myocardial Infarction Following a Teaching Intervention Offered by Nurses) trial, a multicenter randomized clinical trial to reduce patient prehospital delay to treatment in ACS. RESULTS Of the 3522 subjects with CAD enrolled into the trial, 3087 subjects completed 2-year follow-up. Of these, 331 subjects sought treatment in the emergency department for ACS symptoms and 276 patients (83%) had complete information on the time of symptom onset from both sources. Of the 276 patients, 25 (9%) had differing times more than 48 hours and were thus excluded. The median difference between the 2 sources was 45.0 minutes. When both times were examined, there were no significant differences in time by sex (P = .720) or by age group (P = .188). The median number of days between the interview and the date of symptom onset was 29.5 days. There was a significant correlation between differences in the time of symptom onset and the length of recall period (rs = 0.148, P = .023). In multivariable modeling, a longer recall period was associated with greater median differences in the symptom onset time (b = 13.2, P = .023). CONCLUSION These results suggest that the time of symptom onset obtained at the time of the index event and documented in the MR is not interchangeable with data obtained later by research staff, especially if the interview is not conducted near the time of the index event.

Abstract
The objective of this article was to review the effects of acute intracranial lesions on myocardial function. The authors reviewed scientific and clinical literature retrieved from a computerized MEDLINE search from January 1965 through January 2002. Pertinent literature was referenced, including clinical and laboratory investigations, to demonstrate the effects of acute intracranial lesions on the cardiovascular system. The literature was reviewed to summarize the mechanisms of cardiac damage and clinical manifestations and treatment of cardiovascular dysfunction caused by acute intracranial lesions. Myocardial damage and rhythm disturbances were shown to occur with acute intracranial neurological disease. The subgroup of patients used in this study formed a substantial pool of cardiac donors for cardiac transplantation. The pathophysiology of myocardial dysfunction and the optimal management continues to be a source of debate. In this article, the authors will review the anatomy, the available evidence of the pathophysiology, and the management of this complex group of patients. They will also discuss areas that need to be further investigated. Cardiovascular effects of acute intracranial lesions are common and contribute to increased morbidity and mortality.

Abstract
Background: The time interval from symptom onset to hospital arrival can guide the decision to start reperfusion for patients with acute myocardial infarction (AMI). Aims: The aims of the study were 1) to examine the consistency and agreement of prehospital delay time between medical record review and structured patient interview and 2) to identify whether symptom severity is an independent predictor of differences in reported prehospital delay between these two data sources. Methods: In this cross-sectional study, a convenience sample of 155 patients with AMI in Japan was recruited. The time and date of symptom onset were obtained from medical record review and a structured patient interview. The interviewer asked about severity of symptoms, using a scale on 0 to 10 scale, with 0 being “no symptom” and 10 being “the most severe symptoms imaginable”. Results: The prehospital delay time from the medical record was significantly shorter than from the structured interview. Perfect agreement of reported prehospital delay time between two data sources was found in 46% of patients. Patients with symptom severity scores of greater than 8 on a 10-point scale were 2.2 times (95% CI: Odds Ratio 1.1 to 5.1) more likely to report different symptom onset time. Conclusions: Prehospital delay time documented in the medical record was shorter than that identified from a structured interview. In addition, the discrepancy between the two data sources may be larger in those patients with severe AMI symptoms.

Abstract
The health of older people is a priority in many countries as the world's population ages. Attitudes towards help seeking behaviours in older people remain a largely unexplored field of research. This is particularly true for older minority groups where the place that they have migrated to presents both cultural and structural challenges. The UK, like other countries, has an increasingly aging Chinese population about who relatively little is known. This study used a qualitative grounded theory design following the approach of Glaser (1978). Qualitative data were collected using semi-structured interviews with 33 Chinese elders who were aged between 60 and 84, using purposive and theoretical sampling approaches. Data were analysed using the constant comparative method until data saturation occurred and a substantive theory was generated. “Being healthy” (the core category) with four interrelated categories: self-management, normalizing/minimizing, access to health services, and being cured form the theory. The theory was generated around the core explanations provided by participants and Chinese elders’ concerns about health issues they face in their daily life. We also present data about how they direct their health-related activities towards meeting their physical and psychological goals of being healthy. Their differential understanding of diseases and a lack of information about health services were potent predictors of non–help seeking and “self” rather than medical management of their illnesses. This study highlights the need for intervention and health support for Chinese elders.

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
Background Many critical treatment decisions are based on the medical history of patients with an acute coronary syndrome (ACS). Discrepancies between the medical history documented by a health professional and the patient's own report may therefore have important health consequences. Methods Medical histories of 117 patients with an ACS were documented. A questionnaire assessing the patient's health history was then completed by 62 eligible patients. Information about 13 health conditions with relevance to ACS management was obtained from the questionnaire and the medical record. Concordance between these two sources and reasons for discordance were identified. Results There was significant variation in agreement, from very poor in angina (kappa < 0) to almost perfect in diabetes (kappa = 0.94). Agreement was substantial in cerebrovascular accident (kappa = 0.76) and hypertension (kappa = 0.73); moderate in cocaine use (kappa = 0.54), smoking (kappa = 0.46), kidney disease (kappa = 0.52) and congestive heart failure (kappa = 0.54); and fair in arrhythmia (kappa = 0.37), myocardial infarction (kappa = 0.31), other cardiovascular diseases (kappa = 0.37) and bronchitis/pneumonia (kappa = 0.31). The odds of agreement was 42% higher among individuals with at least some college education (OR = 1.42; 95% CI, 1.00 - 2.01, p = 0.053). Listing of a condition in medical record but not in the questionnaire was a common cause of discordance. Conclusion Discrepancies in aspects of the medical history may have important effects on the care of ACS patients. Future research focused on identifying the most effective and efficient means to obtain accurate health information may improve ACS patient care quality and safety.

Abstract
BACKGROUND The impact of delayed presentation on the management and outcomes of patients with non-ST-elevation acute coronary syndromes (NSTE-ACS) has not been well studied. Furthermore, the prognostic value of initial biomarker level in relation to the time of presentation has not been determined. METHODS The Canadian ACS II registry was a national, multicenter, prospective observational study of 1,956 patients with NSTE-ACS (October 2002-December 2003). We compared the baseline characteristics, treatment, and outcomes in early (within 6 hours of symptom onset) versus late presenters (>6 hours). A logistic regression model was developed to examine the independent association of late presentation with 1-year mortality. We also evaluated the prognostic value of initial biomarker level in relation to early versus late presentation. RESULTS A total of 1,219 (62.3%) patients presented early, whereas 727 (37.7%) presented late; their rates of in-hospital revascularization were similar (40.5% vs 42.5%, respectively, P = .39). There was also no significant difference in hospital mortality (1.6% vs 2.2%, P = .30) or 1-year mortality (7.6% vs 5.7%, P = .13) between early and late presenters. After adjusting for other prognosticators, late presentation was not an independent predictor of 1-year mortality (adjusted odds ratio 0.78, 95% confidence interval 0.48-1.26, P = .3). Elevated initial biomarker was independently associated with higher 1-year mortality (adjusted odds ratio 2.17, 95% CI 1.31-3.58, P = .002) regardless of whether hospital presentation was early or late (P for interaction = .74). CONCLUSIONS There is still considerable delay between symptom onset of NSTE-ACS and hospital presentation in the contemporary era. In contrast to studies of ST-elevation myocardial infarction, we found no significant differences in the management and outcome of early presenters as compared with late presenters with NSTE-ACS. Nevertheless, measures to reduce patient delay time should continue to be implemented. Initial biomarker status is a useful prognosticator irrespective of the delay time.

Abstract
OBJECTIVE To study in myocardial infarction (MI) whether documentation of ischaemic symptoms is associated with quality of care and outcomes, and to compare patient reports of ischaemic symptoms during interviews with chart documentation. DESIGN Observational acute MI study from 2003 to 2004 (Prospective Registry Evaluating Myocardial Infarction: Event and Recovery). SETTING 19 diverse US hospitals. PATIENTS 2094 consecutive patients with MI (10 911 patients screened; 3953 patients were eligible and enrolled) with both positive cardiac enzymes and other evidence of infarction (eg, symptoms, electrocardiographic changes). Transferred patients and those with confounding non-cardiac comorbidity were not included (n = 1859). MAIN OUTCOME MEASURES Quality of care indicators and adjusted in-hospital survival. RESULTS The records of 10% of all patients with MI (217/2094) contained no documented ischaemic symptoms at presentation. Patients without documented symptoms were less likely (p<0.05) to receive aspirin (89% vs 96%) or beta-blockers (77% vs 90%) within 24 hours, reperfusion therapy for ST-elevation MI (7% vs 58%) or to survive their hospitalisation (adjusted odds ratio = 3.2, 95% CI 1.8 to 5.8). Survivors without documented symptoms were also less likely (p<0.05) to be discharged with aspirin (87% vs 93%), beta-blockers (81% vs 91%), ACE/ARB (67% vs 80%), or smoking cessation counselling (46% vs 66%). In the subset of 1356 (65%) interviewed patients, most of those without documented ischaemic symptoms (75%) reported presenting symptoms consistent with ischaemia. CONCLUSIONS Failure to document patients' presenting MI symptoms is associated with poorer quality of care from admission to discharge, and higher in-hospital mortality. Symptom recognition may represent an important opportunity to improve the quality of MI care.

Abstract
BACKGROUND Prompt hospital admission is essential when treating acute coronary syndrome. Delay prior to admission is unnecessarily long. Therefore, a thorough scrutiny of the influence of characteristics, circumstantial and subjective variables on elements of prehospital delay among patients admitted with acute coronary syndrome is warranted. METHODS A structured interview was conducted on 250 consecutive patients admitted alive with acute coronary syndrome. RESULTS Median prehospital, decision, physician and transportation delays were 107, 74, 25 and 22 min, respectively. Women (n=77) had more frequently atypical symptoms and increased prehospital delay caused by prolonged physician and transportation delay. Physician delay among women and men were 69 and 16 min, respectively. Patients with prior myocardial infarction had reduced prehospital delay, which was caused by shorter decision and physician delay; whereas patients with prior mechanical revascularisation or typical symptoms had prolonged prehospital delay due to long decision delay. When symptoms were interpreted as cardiac the decision and prehospital delay were reduced. CONCLUSION The medical profession underestimates the risk of acute coronary syndrome among women, and thereby contributes to unnecessary long delay to treatment. The patient's prior experience and interpretation has a significant influence on behaviour.

Abstract
Delays in seeking medical attention for patients with acute coronary syndromes (ACS) preclude early application of life-saving treatment and diminish efficacy. Previous studies suggest 3-hour delays between onset of symptoms and ED arrival in patients with typical presentations of acute myocardial infarction (AMI). A prospective observational study was conducted in an urban ED measuring lag time (LT) among adults presenting within 48 hours of onset of symptoms suggestive of ACS. Univariate and multiple regression analyses were performed on 5 predictors: age, sex, symptoms at presentation, and 2 different outcomes (AMI and ACS). Three hundred seventy-four patients were enrolled. Mean age was 63 years with 38% 70 years or older. Seventy-three percent of all patients with suspected ACS presented with chest pain, 27% with atypical symptoms. Overall mean LT was 8.7 hours (standard deviation 11). In subgroup analysis, patients aged >/=70 years were more likely to have LTs >12 hours (29% vs. 19% P =.043) and patients without chest pain had longer mean LTs (11.6 vs. 7.6 hours, P =.01). Delay in ED presentation is group specific. Advanced age and patients with atypical symptoms are predictive of longer LTs. Contrary to previously published data, patients with symptoms suspicious for ACS can delay an average of 9 hours, which might alter current thinking in the prevention and care of these patients.

Abstract
Early reperfusion significantly reduces mortality and morbidity in patients with acute myocardial infarction [2-6]. Prehospital 12-lead ECG programs significantly decrease time to definitive reperfusion therapy [8-13]. The feasibility and safety of prehospital 12-lead ECG programs are well [figure: see text] established [8,11,13,14]. Additional potential benefits include increased diagnostic accuracy in the prehospital setting [14], providing a comparison ECG to the one obtained in-hospital [15], differentiating arrhythmias [16-18], and sensitive and specific computerized ECG interpretation [31,32]. Prehospital 12-lead ECG diagnostic programs also provide the necessary clinical information to implement system changes or interventions such as prehospital thrombolytic therapy, direct CCU admission, or triage to tertiary cardiac care centers [22,30,34,35]. The information acquired should be used optimally to effect significant improvements in patient care through a well planned and coordinated program.

Abstract
Cardiovascular disease and stroke are the nation's leading causes of disability and death. Scientific advances have provided newer treatments that, when applied effectively and in time, save a significant number of lives. Multiple factors in our system of delivery impede our ability to apply effective treatments, but with an analysis of the components of care, each of us can take leadership roles in our communities to improve the chain of survival. These elements and the science supporting each are briefly reviewed.

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
BACKGROUND Available clinical criteria to estimate prognosis in patients with evolving ST-segment elevation myocardial infarction do not consider the impact of reperfusion therapy and do not incorporate measurement of baseline levels of cardiac serum markers. We evaluated the combination of a baseline myoglobin assay and early (60- to 90-minute) ST resolution for risk stratification after ST-segment elevation myocardial infarction. METHODS In a prospective substudy of the Intravenous nPA for Treatment of Infarcting Myocardium Early-II (InTIME-II) trial carried out in 2079 patients, a rapid qualitative assay for myoglobin was performed immediately before thrombolysis. Serial 12-lead electrocardiograms were performed at baseline and 60 to 90 minutes after thrombolysis. ST resolution was categorized as complete (>/=70%), partial (30% to <70%), or none (<30%). RESULTS Mortality rate at 30 days was 3.3% in the 905 patients with a negative baseline myoglobin assay versus 8.9% in the 527 patients with a positive assay (P <.0001). Mortality rate was lowest (2.4%) among the 614 patients with complete ST resolution, intermediate (4.9%) among the 512 patients with partial ST resolution, and highest (8.1%) among the 540 patients with no ST resolution (P <.0001 for trend). In a logistic regression model incorporating other baseline predictors of 30-day mortality rate, both a positive myoglobin assay (relative risk 1.98, 95% confidence interval 1.00-3.90) and ST resolution <70% (relative risk 2.86, 95% confidence interval 1.22-6.69) were independently associated with increased mortality rate. At 30 days, mortality rate was 0.4% among patients with a negative myoglobin assay and complete ST resolution, 4.8% among patients with either a positive myoglobin assay or ST resolution <70%, and 9.6% among those with both a positive myoglobin ratio and ST resolution <70% (P <.001 for trend). CONCLUSIONS Within 90 minutes after administering thrombolytic therapy for acute myocardial infarction, clinicians can determine the risk for death at the patient's bedside with a hand-held myoglobin assay and 2 serial 12-lead electrocardiograms. A strategy using these 2 simple, rapid, and inexpensive tests may facilitate triage after thrombolytic therapy.

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
INTRODUCTION Methods to characterize the interval between a collapse from cardiac arrest until a 911 call is made have not yet been developed. OBJECTIVE To determine the concordance of cardiac arrest data obtained by two methods: an immediate nurse interview of out-of-hospital cardiac arrest (OHCA) witnesses, and a follow-up phone interview performed two weeks later. METHODS This was a prospective study of OHCA witnesses dating from January 1997 to May 1998. Witnesses were briefly interviewed at the time of emergency department presentation, and two weeks later a more lengthy structured phone interview was performed. The authors identified key data elements: 1) was the arrest witnessed? (Wit); 2) was CPR administered prior to EMS arrival? (BCPR); 3) was the first call placed to 911? (c911); and 4) was the estimated collapse to call interval <4 minutes? (ECCI). The analysis utilized Cohen's kappa statistic and Spearman's correlation coefficient. RESULTS A convenience sample of 42 matched pairs of OHCA cases was analyzed. Kappa statistics for agreement between methods were: 1) Wit(kappa = 0.750), 2) BCPR(kappa = 0.892), 3) c911 (kappa = 0.892), and 4) ECCI(kappa = 0.571, Spearman's 0.528). CONCLUSION There is good to excellent agreement between immediate and phone interview data retrieval methods. Phone interviews appear to yield data comparable to that with the more difficult and expensive, direct interview method.
