International Comparison of Factors Associated with Delay in Presentation for AMI Treatment

Association of Symptoms and Mode of Transportation to Emergency Department in Patients With Acute Coronary Syndrome

BACKGROUND

Patients with acute coronary syndrome (ACS) with symptoms matching their expectations of a heart attack are more likely to use emergency medical services (EMS) than not.

OBJECTIVE

To determine whether presenting symptom clusters are associated with EMS use in ACS patients and if EMS use or symptom clusters are associated with prehospital delay.

METHODS

This secondary analysis used data from the PROMOTION trial, a randomized clinical trial that enrolled 3522 subjects with a history of or at risk for ACS from 5 sites in the United States, Australia, and New Zealand. Subjects were randomized to usual care or an educational intervention to reduce prehospital delay. During the 2-year follow-up, subjects admitted for ACS were asked about symptoms, time of symptom onset, and mode of transportation to the hospital. Symptoms were grouped into classic ACS, pain symptoms, and stress symptoms clusters.

RESULTS

Of 3522 subjects enrolled, 331 sought care for ACS during follow-up; 278 had transportation mode documented; 121 (44%) arrived via EMS. Classic ACS plus pain symptoms (adjusted odds ratio [AOR], 2.66; P = .011), classic ACS plus stress symptoms (AOR, 2.61; P = .007), and classic ACS plus both pain and stress symptoms (AOR, 3.90; P = .012) were associated with higher odds of EMS use versus classic ACS symptoms alone. Emergency medical services use resulted in a 68.5-minute shorter median delay (P = .002) versus non-EMS use. Symptom clusters were not predictive of delay time in the adjusted model (P = .952).

DISCUSSION

Although chest symptoms were the most prevalent symptoms for most (85%), the combination of classic ACS symptoms with other symptom clusters was associated with higher EMS use. Further research is needed to determine whether a combination of symptom clusters helps patients correctly interpret ACS symptoms to better understand how symptom clusters influence EMS use.

Barriers associated with emergency medical service activation in patients with ST-segment elevation acute coronary syndromes

Many ST-segment elevation acute coronary syndrome (STEACS) patients fail to activate the Emergency Medical System (EMS), with possible dramatic consequences. Prior studies focusing on barriers to EMS activation included patients with any acute coronary syndrome (ACS) without representation of southern European populations. We aimed to investigate the barriers to EMS call for patients diagnosed for STEACS in Italy. A prospective, single-center, survey administered to all patients treated with primary percutaneous coronary intervention for STEACS in a tertiary hospital in northern Italy from 01/06/2018 to 31/05/2020. The questionnaire was filled out by 293 patients. Of these, 191 (65.2%) activated the EMS after symptoms onset. The main reasons for failing to contact EMS were the perception that the symptoms were unrelated to an important health problem (45.5%) and that a private vehicle is faster than EMS to reach the hospital (34.7%). Patients who called a private doctor after symptoms onset did not call EMS more frequently than those who did not and 30% of the patients who did not call the EMS would still act in the same way if a new episode occurred. Previous history of cardiovascular disease was the only predictor of EMS call. Information campaigns are urgently needed to increase EMS activation in case of suspected STEACS and should be primary focused on patients without cardiovascular history, on the misperception that a private vehicle is faster than EMS activation, and on the fact that cardiac arrest occurs early and may be prevented by EMS activation.

Comparisons of Prehospital Delay and Related Factors Between Acute Ischemic Stroke and Acute Myocardial Infarction

Background

Prehospital delay is an important contributor to poor outcomes in both acute ischemic stroke (AIS) and acute myocardial infarction (AMI). We aimed to compare the prehospital delay and related factors between AIS and AMI.

Methods and Results

We identified patients with AIS and AMI who were admitted to the 11 Korean Regional Cardiocerebrovascular Centers via the emergency room between July 2016 and December 2018. Delayed arrival was defined as a prehospital delay of >3 hours, and the generalized linear mixed‐effects model was applied to explore the effects of potential predictors on delayed arrival. This study included 17 895 and 8322 patients with AIS and AMI, respectively. The median value of prehospital delay was 6.05 hours in AIS and 3.00 hours in AMI. The use of emergency medical services was the key determinant of delayed arrival in both groups. Previous history, 1‐person household, weekday presentation, and interhospital transfer had higher odds of delayed arrival in both groups. Age and sex had no or minimal effects on delayed arrival in AIS; however, age and female sex were associated with higher odds of delayed arrival in AMI. More severe symptoms had lower odds of delayed arrival in AIS, whereas no significant effect was observed in AMI. Off‐hour presentation had higher and prehospital awareness had lower odds of delayed arrival; however, the magnitude of their effects differed quantitatively between AIS and AMI.

Conclusions

The effects of some nonmodifiable and modifiable factors on prehospital delay differed between AIS and AMI. A differentiated strategy might be required to reduce prehospital delay.

Surviving to Acute Myocardial Infarction: The Role of Psychological Factors and Alexithymia in Delayed Time to Searching Care: A Systematic Review

The time from symptom onset to reperfusion is a critical determinant of myocardial salvage and clinical outcomes in patients with acute myocardial infarction (AMI). This time period could be delayed if people do not seek help promptly and/or if the health system is not efficient in responding quickly and attending to these individuals. The aim of this study was to identify psychological factors associated with pre-hospital delay (PHD) or patients' decisional delay (PDD) in people with an ongoing AMI. A search in PubMed/Medline from 1990 to 2021 with the keywords "pre-hospital delay" OR "prehospital delay" OR "patient delay" OR "decisional delay" OR "care seeking behavior" AND "psychological factors" OR "alexithymia" AND "myocardial infarction" was performed. Thirty-six studies were included, involving 10.389 patients. Wrong appraisal, interpretation and causal beliefs about symptoms, denial of the severity of the symptoms and high levels of alexithymia were found related to longer PHD or PDD. Alexithymia may be an overarching construct that explains the disparate findings of the studies exploring the role of psychological factors in PHD or PDD. Further studies are needed in order to analyse the role of alexithymia in patients with risk factors for AMI to prevent delay.

Knowledge of Heart Disease, Preventive Behavior and Source of Information in a Multi-ethnic Asian Population: A Population-Based Survey

Several population-based studies have been conducted to better understand the public knowledge of cardiovascular disease (CVD) and behavior. However, most studies have predominantly focused on Western populations. This study aimed to investigate heart disease knowledge, preventive behavior and source of information on heart disease in a multi-ethnic Asian population. We conducted a nation-wide population-based survey of 1000 participants of three ethnic groups (Chinese, Malay, Indian) in Singapore. A structured questionnaire was used to collect sociodemographics, knowledge on CVD risk factors, symptoms, emergency action, preventive health behaviors and sources of information on heart disease. Univariate and multivariate analyses were conducted to identify factors associated with the CVD knowledge and behavior. Knowledge on CVD risk factors was generally high. Knowledge on emergency actions was low particularly in younger people. More than 60% did not meet the recommended levels of physical activity, and this was more evident for individuals of overweight/obese status, lower education and workforce. Chinese were less likely to be obese/overweight compared to the Malays and Indians. Malays were less likely to seek information from internet and social media compared to their ethnic counterparts. This study highlighted heterogeneity in the levels of knowledge and health behavior across population segments, suggesting the need for a tailored approach to heart health interventions and optimal channels for information dissemination. Our findings will form the basis for contextually and culturally appropriate interventions to combat the growing CVD burden and prevent its toll on a rapidly ageing population.

Pre-hospital Delay and Its Reasons in Patients With Acute Myocardial Infarction Presenting to a Primary Percutaneous Coronary Intervention-Capable Center

Objective

This study aimed to assess the duration of pre-hospital delay among ST-Segment Elevation Myocardial Infarction (STEMI) patients and its contributing factors.

Methodology

A cross-sectional study was conducted at Rural Satellite Center in Larkana, Pakistan from May to September 2020. A total of 240 STEMI patients who underwent primary percutaneous coronary intervention (P-PCI) were included. The patients' demographic characteristics, index event characteristics, mode of transportation, misinterpretations, misdiagnoses, and financial problems were recorded. Data were analyzed using SPSS version 22.0 (IBM Corp., Armonk, NY, USA).

Results

The observed pre-hospital time was 120 minutes; 229 (median; interquartile range [IQR]). It was found that 33.3% of patients arrived within one hour of the symptom onset, while 20.4% of patients delayed hospital arrival for more than six hours. The delay rate was highest among patients aged 41 to 65 years. Moreover, delayed admissions were more common among females as compared to males (p=0.008). Among the causes of delay in hospital arrival were misinterpretation, misdiagnosis, and transportation and financial issues. Of these, misdiagnosis significantly influenced the delay rate, i.e., more than 50% of the misdiagnosed patients arrived hospital after six hours of symptom onset (p<0.05).

Conclusion

The P-PCI rural satellite center had a positive impact as the observed pre-hospital delay rate was considerably less as compared to that reported in the existing literature. Moreover, the confounding factors were misdiagnosis and misinterpretations. We need to develop the concept of immediate appropriate help-seeking among patients.

Public knowledge of risk factors and warning signs for cardiovascular disease among young and middle-aged adults in rural Tanzania

Background

Improving cardiovascular health requires public knowledge and reduction of modifiable cardiovascular disease (CVD) risk factors. This study assessed knowledge of risk factors and warning signs for CVDs among young and middle-aged adults in Morogoro, Tanzania.

Methods

We conducted a community-based survey as part of cluster randomized controlled study of community health workers (CHWs) intervention for reduction of blood pressure among young and middle-aged adults in rural Morogoro. Information on socio-demographic characteristics, knowledge of risk factors and warning signs for CVDs was collected using an interviewer administered questionaire. Knowledge was assessed using open-ended questions followed by closed-ended questions. Descriptive statistics were used to describe knowledge of risk factors and warning signs. Logistic regression analysis was used to investigate factors associated with adequate knowledge of risk factors and warning signs for CVDs.

Results

Two-thirds (65.7%) of the participants had heard about CVDs. The main sources of information were mainly relatives/ neighbors (64.8%) and radio (53.0%). Only 28.3% of the participants reported health care providers as source of information about CVDs. More than half of the participants (52.4%) did not mention even one risk factor spontaneously while 55.2% were unable to mention any warning sign. When asked to select from a list, 6.9% were unable to correctly identify any risk factor whereas 11.8% could not correctly identify even a single warning sign. Quarter of participants (25.4%) had good knowledge score of risk factors, 17.5% had good knowledge score of warning signs and 16.3% had overall good knowledge of both risk factors and warning signs. Residing in Ulanga, having higher education level, having ever checked blood pressure and being overweight/obese predicted adequacy of knowledge score for both risk factors and warning signs.

Conclusion

Knowledge of risk factors and warning signs in this rural population of young and middle-aged adults was generally low. Health care providers were less likely to provide health education regarding risk factors and warning signs for CVDs. Health promotion interventions to increase population knowledge of risk factors and warning signs should be implemented for successful reduction of CVDs in Tanzania.

Cardiac symptom attribution and knowledge of the symptoms of acute myocardial infarction: a systematic review

BACKGROUND

Since the knowledge of the symptoms of acute myocardial infarction (AMI) may reduce the decision time for patients to seek help in case of an AMI, we aimed to summarize evidence on the knowledge of the AMI symptoms and the symptom attribution in case of an acute coronary syndrome (ACS).

METHODS

Therefore, we systematically searched the databases PubMed, CINAHL, Embase, and Cochrane Library for relevant studies published between January 1, 2008 and 2019 (last search August 1, 2019).

RESULTS

A total of 86 studies were included, with a composite sample size of 354,497 participants. The weighted mean of the knowledge scores for the symptoms of AMI of 14,420 participants from the general population, was 42.1% (when maximum score was considered 100%) and 69.5% for 7642 cardiac patients. There was a substantially better level of knowledge for six symptoms ('chest pain or discomfort', 'shortness of breath', 'pain or discomfort in arms or shoulders', 'feeling weak, lightheaded, or faint', 'pain or discomfort in the jaw, neck, or back', and 'sweating') (49.8-88.5%) compared to the four less obvious/atypical symptoms 'stomach or abdominal discomfort', 'nausea or vomiting', 'headache', and 'feeling of anxiety' (8.7-36.7%). Only 45.1% of 14,843 patients, who experienced ACS, have correctly attributed their symptoms to a cardiac cause.

CONCLUSION

In conclusion, we found a moderate to good knowledge of "classic" and insufficient knowledge of less obvious symptoms of AMI. This might suggest that increasing knowledge about less obvious symptoms of AMI could be beneficial. It appears also important to address cardiac attribution of symptoms.

Awareness of cardiovascular disease associated risk factors among Saudis in Riyadh City

Objective:

The aim of this study was to estimate the awareness of Saudi population in Riyadh regarding cardiovascular diseases (CVDs) and their risk factors.

Methods:

This was a cross-sectional study that used self-administered questionnaires conducted in universities, primary care centers, and electronic copies distributed in social media websites.

Results:

Overall, 47.1% of the respondents had a good awareness of CVD and associated risk factors. However, awareness of the symptoms of stroke and heart attack was low. Pulmonary embolism and deep vein thrombosis were the most commonly identified types of CVD, with 39.2% aware of these conditions. The most well-known symptom of heart attack was shortness of breath (known by 54.4% of the respondents). In relation to stroke, the most commonly recognized symptom was “sudden dizziness, trouble walking, or loss of balance” (45.4%). Respondents’ awareness of CVD risk factors was moderate. The most common factors—identified by over two-thirds of participants—were unhealthy diet, smoking, dyslipidemia, and physical inactivity. Independent predictors of good CVD awareness were age 35–44 years, living in the north of Riyadh and following a healthy diet.

Conclusions:

The awareness of CVD and associated risk factors is insufficient among Saudis in Riyadh City. This study emphasizes the necessity for effective education to increase the awareness about CVD in Saudi Arabia. High awareness may lead to early recognition of the risk factors and lead to early implementation of primary prevention which the cornerstone of family medicine practice.

Psychological and cognitive factors related to prehospital delay in acute coronary syndrome: A systematic review

BACKGROUND

In acute coronary syndrome the time elapsed between the start of symptoms and the moment the patient receives treatment is an important determinant of survival and subsequent recovery. However, many patients do not receive treatment as quickly as recommended, mostly due to substantial prehospital delays such as waiting to seek medical attention after symptoms have started.

OBJECTIVE

To conduct a systematic review with meta-analysis of the relationship between nine frequently investigated psychological and cognitive factors and prehospital delay.

DESIGN

A protocol was preregistered in PROSPERO [CRD42018094198] and a systematic review was conducted following PRISMA guidelines.

DATA SOURCES

The following databases were searched for quantitative articles published between 1997 and 2019: Medline (PubMed), Web of Science, Scopus, Psych Info, PAIS, and Open grey.

REVIEW METHODS

Study risk of bias was assessed with the NIH Quality Assessment Tool for Observational, Cohort, and Cross-Sectional Studies. A best evidence synthesis was performed to summarize the findings of the included studies.

RESULTS

Forty-eight articles, reporting on 57 studies from 23 countries met the inclusion criteria. Studies used very diverse definitions of prehospital delay and analytical practices, which precluded meta-analysis. The best evidence synthesis indicated that there was evidence that patients who attributed their symptoms to a cardiac event (n = 37), perceived symptoms as serious (n = 24), or felt anxiety in response to symptoms (n = 15) reported shorter prehospital delay, with effect sizes indicating important clinical differences (e.g., 1.5-2 h shorter prehospital delay). In contrast, there was limited evidence for a relationship between prehospital delay and knowledge of symptoms (n = 18), concern for troubling others (n = 18), fear (n = 17), or embarrassment in asking for help (n = 14).

CONCLUSIONS

The current review shows that symptom attribution to cardiac events and some degree of perceived threat are fundamental to speed up help-seeking. In contrast, social concerns and barriers in seeking medical attention (embarrassment or concern for troubling others) may not be as important as initially thought. The current review also shows that the use of very diverse methodological practices strongly limits the integration of evidence into meaningful recommendations. We conclude that there is urgent need for common guidelines for prehospital delay study design and reporting.

Psychosocial markers of pre-hospital decision delay and psychological distress in acute coronary syndrome patients

Objectives Both pre-hospital decision delay - the time patients wait before seeking medical attention after symptoms have started - and high psychological distress after the cardiac episode predict poor prognosis of patients with acute coronary syndromes (ACS). We aimed to identify psychosocial markers of these prognostic factors. Design A cross-sectional study of 102 consecutive, clinically stable ACS survivors. Methods Participants completed a questionnaire measuring pre-hospital decision delay, psychological distress, and several known psychosocial factors related to cardiovascular health: type D personality, resilience, social support, and concerns during the cardiac event. Multiple linear regression and mediation analyses were conducted. Results Type D personality and fewer concerns about the serious consequences of delaying help-seeking were related to more psychological distress post-ACS, and these relationships were mediated by longer pre-hospital decision delay. In contrast, resilience was related to lower psychological distress. Social support and social concerns about help-seeking were not related to the outcome variables. Conclusions Type D personality may be a risk factor for more delayed help-seeking for an ACS and higher psychological distress after the cardiac event. Resilience, in contrast, emerged as a potential protective factor of patients' mental health after the cardiac event. Pre-hospital decision delay was related to thinking about serious consequences (e.g., complications, protecting one's family) but not about social concerns (e.g., wasting other people's time) during the cardiac episode. Statement of Contribution What is already known on this subject? Longer pre-hospital decision delay, that is waiting longer to seek medical attention after symptoms have started, predicts poor prognosis of acute coronary syndrome patients. High psychological distress post-ACS, such as the development of anxiety and/or depression, also predicts poor prognosis of these patients. What does this study adds? This study identifies several psychosocial markers of longer prehospital decision delay and high psychological distress post-ACS. Prehospital decision delay was related to thinking about serious consequences (e.g., complications, protecting one's family) but not about social concerns (e.g., wasting other people's time) during the cardiac episode. Type D personality and fewer concerns about the serious consequences of delaying help-seeking were related to more psychological distress, and these relationships were mediated by longer prehospital decision delay. Resilience was related to lower psychological distress post-ACS.

Determinants of Self-Care in Patients With Heart Failure: Observations From a Developing Country in the Middle East

Introduction: Self-care is recognized as a means for improving outcomes of heart failure (HF), yet studies have not addressed what predicts successful self-care in collectivist cultures like Lebanon. Methodology: Self-care was measured, using the Arabic Self-Care of HF index, in 100 participants with HF (76% males; mean age 67.59) recruited from a tertiary medical center. Results: Self-care was suboptimal, with mean scores of 67.26, 66.96, and 69.5 for self-care maintenance, management, and confidence. Better HF knowledge, social support, and self-care confidence and lower New York Heart Association score predicted better self-care maintenance. Better knowledge, social support, and self-care maintenance, no recent hospitalization, and being unemployed predicted better self-care confidence. Better self-care confidence, maintenance, and HF knowledge predicted better self-care management. Discussion: HF self-care in Lebanon is suboptimal. Nurses need to identify facilitators of and barriers to self-care particular to this population. Interventions targeting HF knowledge, confidence, and caregiver support are expected to improve self-care in Lebanese patients.

Inability to act was associated with an extended delay prior to care-seeking, in patients with an acute myocardial infarction

BACKGROUND

The out-of-hospital mortality in patients with acute myocardial infarction remains unchanged in contrast to a decrease in inhospital mortality. Interventions aiming to shorten patient delay have been largely unsuccessful. A deeper understanding is apparently needed on patients' appraisal prior to care-seeking.

AIM

To investigate whether appraisal processes influence patient delay, and if the questionnaire 'Patients' appraisal, emotions and action tendencies preceding care seeking in acute myocardial infarction' (PA-AMI) could discriminate between patients with prolonged care-seeking and those with a short delay.

METHODS

A cross-sectional study including 326 acute myocardial infarction patients filling out the validated questionnaire PA-AMI. The impact of subscales on delay was analysed by projection to latent structures regression. Discrimination opportunities between patients with short and long delays were analysed by projection to latent structures discriminant analysis.

RESULTS

The subscales 'perceived inability to act' and 'symptom appraisal' had a major impact on patient delay (P<0.0001). 'Perceived inability to act' had its main influence in patients with a delay exceeding 12 hours, and 'symptom appraisal' had its main influence in patients with a delay shorter than one hour.

CONCLUSION

Appraisal processes influence patient delay. Acute myocardial infarction patients with a prolonged delay were, besides a low perceived symptom severity and urgency to seek medical care, characterised by a perceived loss of control and ability to act. Therefore, future interventions aimed at decreasing delay should pay attention to appraisal processes, and perceived inability to act may be a sign of a health threat and therefore a signal to seek medical care.

The MEDEA FAR-EAST Study: Conceptual framework, methods and first findings of a multicenter cross-sectional observational study

BACKGROUND

The substantial increase in cardiovascular diseases (CVD) in China over the last three decades warrants comprehensive preventive primary and secondary strategies. Prolonged prehospital delay (PHD) has been identified as a substantial barrier to timely therapeutic interventions for acute myocardial infarction (AMI). Despite worldwide efforts to decrease the patient's decision-making time, minimal change has been achieved so far. Here, we aim to describe the conceptual framework and methods and outline key data of the MEDEA FAR-EAST Study, which aimed to elucidate in-depth barriers contributing to delay in Chinese AMI-patients.

METHODS

Data sources of this multicenter cross-sectional observational study are a standardized bedside interview, a self-administered tailored questionnaire tool and the patient chart. PHD was defined as the main outcome and triangulated at bedside. Standard operation procedures ensured uniform data collection by trained study personnel. The study was ethically approved by Tongji-Hospital and applied to all participating hospitals.

RESULTS

Among 379 consecutively screened patients, 296 (78.1%) fulfilled eligibility criteria. A total of 241 (81.4%) AMI-patients were male and 55 (18.6%) female. Mean age was 62.9 years. Prehospital delay time was assessed for 294 (99.3%) patients. Overall median PHD was 151 min with no significant sex difference. Symptom mismatch was present in 200 (69.7%) patients and 106 (39.0%) patients did not attribute their symptoms to cardiac origin. A total of 33 (12.4%) patients suffered from depression, 31 (11.7%) from anxiety and 141 (53.2%) patients employed denial as their major coping style.

CONCLUSION

This is the first study on prehospital delay with emphasis on psychological variables in Chinese AMI-patients. A comprehensive assessment tool to measure clinical and psychological factors was successfully implemented. Socio-demographic key data proved a good fit into preexisting Chinese literature. Potential barriers including cardiac denial and symptom-mismatch were assessed for the first time in Chinese AMI-patients. The pretested selection of instruments allows future in depth investigations into barriers to delay of Chinese AMI-patients and enables inter-cultural comparisons.

Time to hospital arrival among patients with acute myocardial infarction in China: a report from China PEACE prospective study

Aims

Few contemporary studies have reported the time between acute myocardial infarction (AMI) symptoms onset and hospital arrival, associated factors, and patient perceptions of AMI symptoms and care seeking. We sought to study these issues using data from China, where AMI hospitalizations are increasing.

Methods and results

We used data from the China PEACE prospective AMI study of 53 hospitals across 21 provinces in China. Patients were interviewed during index hospitalization for information of symptom onset, and perceived barriers to accessing care. Regression analyses were conducted to explore factors associated with the time between symptom onset and hospital arrival. The final sample included 3434 patients (mean age 61 years). The median time from symptom onset to hospital arrival was 4 h (interquartile range 2–7.5 h). While 94% of patients reported chest pain or chest discomfort, only 43% perceived symptoms as heart-related. In multivariable analyses, time to hospital arrival was longer by 14% and 39% for patients failing to recognize symptoms as cardiac and those with rural medical insurance, respectively (both P < 0.001). Compared with patients with household income over 100 000 RMB, those with income of 10 000–50 000 RMB, and <10 000 RMB had 16% and 23% longer times, respectively (both P = 0.03).

Conclusion

We reported an average time to hospital arrival of 4 h for AMI in China, with longer time associated with rural medical insurance, failing to recognize symptoms as cardiac, and low household income. Strategies to improve the timeliness of presentation may be essential to improving outcomes for AMI in China.

Documenting the impact of stroke in a middle-income country: a Malaysian case study

Purpose: Stroke is an abrupt event that often leaves survivors with long term disabilities, causing role changes, and financial strains on households. The profound impact of stroke on survivors may lead to a decline in quality of life due to the physical, psychological, and social difficulties they experience. Taking Malaysia as an example, this study aimed to explore the impact of stroke on survivors and how health services influence their recovery in low and middle-income countries (LMIC).Method: An ethnographic approach with data obtained primarily through in-depth interviews was used. Twenty-seven participants identified as having suffered a stroke were drawn from a health and demographic surveillance system in Malaysia.Results: The physical and social disruption of the lives of stroke survivors was intensified by the resultant financial constraints placed upon individuals, families and households, compounded by inadequate support from the health, and welfare systems. Despite the disruption to their lives, most participants were, at least in part, able to reestablish their lives through various factors that include a strong family support and active coping strategies.Conclusion: In LMIC, recovery can be shaped by the family unit and through active coping strategies especially those in relation to spirituality.Implications for rehabilitationThe impact of stroke on survivors and lack of specialized stroke care compromise the recovery process and quality of life for stroke survivors in low and middle-income countries.Support from the family and reinforcement of religious coping were judged to successfully aid recovery.Physical and emotional impairments as well as psychosocial wellbeing of survivors in the context of environmental factors need to be addressed.

Micronutrient Deficiency Independently Predicts Time to Event in Patients With Heart Failure

Background Dietary micronutrient deficiencies have been shown to predict event-free survival in other countries but have not been examined in patients with heart failure living in the United States. The purpose of this study was to determine whether number of dietary micronutrient deficiencies in patients with heart failure was associated with shorter event-free survival, defined as a combined end point of all-cause hospitalization and death. Methods and Results Four-day food diaries were collected from 246 patients with heart failure (age: 61.5±12 years; 67% male; 73% white; 45% New York Heart Association [NYHA] class III / IV ) and analyzed using Nutrition Data Systems for Research. Micronutrient deficiencies were determined according to methods recommended by the Institute of Medicine. Patients were followed for 1 year to collect data on all-cause hospitalization or death. Patients were divided according to number of dietary micronutrient deficiencies at a cut point of ≥7 for the high deficiency category versus <7 for the no to moderate deficiency category. In the full sample, 29.8% of patients experienced hospitalization or death during the year, including 44.3% in the high-deficiency group and 25.1% in the no/moderate group. The difference in survival distribution was significant (log rank, P=0.0065). In a Cox regression, micronutrient deficiency category predicted time to event with depression, NYHA classification, comorbidity burden, body mass index, calorie and sodium intake, and prescribed angiotensin-converting enzyme inhibitors, diuretics, or β-blockers included as covariates. Conclusions This study provides additional convincing evidence that diet quality of patients with heart failure plays an important role in heart failure outcomes.

The association between ethnicity and delay in seeking medical care for chest pain: a systematic review

BACKGROUND

Acute coronary syndrome (ACS) is a leading cause of mortality and morbidity worldwide, and chest pain is one of the most common symptoms of ACSs. A rapid response to chest pain by patients and appropriate management by health professionals are vital to improve survival rates.People from different ethnic groups are likely to have different perceptions of chest pain, its severity and the need for urgent treatment. These differences in perception may contribute to differences in response to chests pain and precipitate unique coping strategies. Delay in seeking medical care for chest pain in the general population has been well documented; however, limited studies have focused on delay times within ethnic groups. There is little research to date as to whether ethnicity is associated with the time taken to seek medical care for chest pain. Consequently, addressing this gap in knowledge will play a crucial role in improving the health outcomes of culturally and linguistically diverse (CALD) patients suffering from chest pain and for developing appropriate clinical practice and public awareness for these populations.

OBJECTIVES

The current review aimed to determine if there is an association between ethnicity and delay in seeking medical care for chest pain among CALD populations.

INCLUSION CRITERIA TYPES OF PARTICIPANTS

Patients from different ethnic minority groups presenting to emergency departments (EDs) with chest pain.

TYPES OF EXPOSURE

The current review will examine studies that evaluate the association between ethnicity and delay in seeking medical care for chest pain among CALD populations.

TYPES OF STUDIES

The current review will consider quantitative studies including randomized controlled trials (RCTs), non-RCTs, quasi-experimental, before and after studies, prospective and retrospective cohort studies, case-control studies and analytical cross-sectional studies.

OUTCOMES

The current review will consider studies that measure delay time as the main outcome. The time will be measured as the interval between the time of symptom onset and time to reach an ED.

SEARCH STRATEGY

A comprehensive search was undertaken for relevant published and unpublished studies written in English with no date restriction. All searches were conducted in October 2014. We searched the following databases: MEDLINE, PubMed, Cochrane Central Register of Controlled Trials, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, ProQuest (health databases only), Informit, Sociological Abstracts, Scopus and Web of Science. The search for unpublished studies included a wide range of 'gray literature' sources including national libraries, digital theses repositories and clinical trial registries. We also targeted specific health research, specialist cardiac, migrant health, and emergency medicine organizational websites and/or conferences. We also checked the reference lists of included studies and contacted authors when further details about reported data was required to make a decision about eligibility.

METHODOLOGICAL QUALITY

Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to being included in the review. Validity was assessed using standardized critical appraisal instruments from the Joanna Briggs Institute. Adjudication was produced by the third reviewer.

DATA EXTRACTION

Data were extracted from included articles by two independent reviewers using the standardized data extraction tool from the Joanna Briggs Institute.

DATA SYNTHESIS

The extracted data were synthesized into a narrative summary. Meta-analysis could not be performed due to the heterogeneity of study protocols and methods used to measure outcomes.

RESULTS

A total of 10 studies, with a total of 1,511,382 participants, investigating the association between ethnicity and delay met the inclusion criteria. Delay times varied across ethnic groups, including Black, Hispanic, Asian, South Asian, Southeast Asian and Chinese. Seven studies reported delay in hours and ranged from 1.90 to 3.10 h. Delay times were longer among CALD populations than the majority population. The other three studies reported delay time in categories of time (e.g. <1, <4 and <6 h) and found larger proportions of later presentations to the EDs among ethnic groups compared with the majority groups.

CONCLUSION

There is evidence of an association between ethnicity and time taken in seeking medical care for chest pain, with patients from some ethnic minorities (e.g. Black, Asian, Hispanic and South Asian) taking longer than those of the majority population. Health promotions and health campaigns focusing on these populations are indicated.

[Hospital Arrival Rate within Golden Time and Factors Influencing Prehospital Delays among Patients with Acute Myocardial Infarction]

PURPOSE

This research was done to identify the hospital arrival rate and factors related to prehospital delay in arriving at an emergency medical center within the golden time after symptom onset in patients with acute myocardial infarction (AMI).

METHODS

Data used in the research was from the National Emergency Department Information System of the National Emergency Medical Center which reported that in 2014, 9,611 patients went to emergency medical centers for acute myocardial infarction. Prehospital time is the time from onset to arrival at an emergency medical center and is analyzed by subdividing arrival and delay based on golden time of 2 hour.

RESULTS

After onset of acute myocardial infarction, arrival rate to emergency medical centers within the golden time was 44.0%(4,233), and factors related to prehospital delay were gender, age, region of residence, symptoms, path to hospital visit, and method of transportation.

CONCLUSION

Results of this study show that in 2014 more than half of AMI patients arrive at emergency medical centers after the golden time for proper treatment of AMI. In order to reduce prehospital delay, new policy that reflects factors influencing prehospital delay should be developed. Especially, public campaigns and education to provide information on AMI initial symptoms and to enhance utilizing EMS to get to the emergency medical center driectly should be implemented for patients and/or caregivers.

Prehospital delay and time to reperfusion therapy in ST elevation myocardial infarction

Background:

Despite efforts aimed at reducing the prehospital delay and treatment delay, a considerable proportion of patients with ST elevation myocardial infarction (STEMI) present late and receive the reperfusion therapy after unacceptably long time periods. This study aimed at finding out the patients' decision delay, prehospital delay, door-to-electrocardiography (ECG), door-to-needle, and door-to-primary percutaneous coronary intervention (PCI) times and their determinants among STEMI patients.

Materials and Methods:

A cross-sectional study conducted among 96 patients with STEMI admitted in a tertiary care center in South India. The data were collected using interview of the patients and review of records. The distribution of the data was assessed using Kolmogorov–Smirnov test, and the comparisons of the patients' decision delay, prehospital delay, and time to start reperfusion therapy with the different variables were done using Mann–Whitney U-test or Kruskal–Wallis test based on the number of groups.

Results:

The mean (standard deviation) and median (range) age of the participants were 55 (11) years and 57 (51) years, respectively. The median patients' decision delay, prehospital delay, door-to-ECG, door-to-needle, and door-to-primary PCI times were 75, 290, 12, 75, 110 min, respectively. Significant factors associated (P < 0.05) with patients' decision delay were alcoholism, symptom progression, and attempt at symptom relief measures at home. Prehospital delay was significantly associated (P < 0.05) with domicile, difficulty in arranging money, prior consultation at study center, place of symptom onset, symptom interpretation, and mode of transportation.

Conclusions:

The prehospital delay time among the South Indian population is still unacceptably high. Public education, improving the systems of prehospital care, and measures to improve the patient flow and management in the emergency department are essentially required. The time taken to take ECG and to initiate reperfusion therapy in this study points to scope for improvement to meet the American Heart Association recommended timings.

Patients' knowledge about symptoms and adequate behaviour during acute myocardial infarction and its impact on delay time: Findings from the multicentre MEDEA Study

OBJECTIVE

We aimed to assess whether patients' knowledge about acute myocardial infarction (AMI) has an impact on the prehospital delay-time.

METHODS

This investigation was based on 486 AMI patients who participated in the cross-sectional Munich-Examination-of-Delay-in-Patients-Experiencing-Acute-Myocardial-Infarction (MEDEA) study. A modified German-version of the ACS-Response-Index Questionnaire was used. Multivariate logistic-regression models were used to identify factors associated with knowledge-level as well as the impact of knowledge-level on delay-time.

RESULTS

High AMI-knowledge shortened median delay-time in men (168[92-509] vs. 276[117-1519] mins, p=0.0069), and in women (189[101-601] vs. 262[107-951]mins, p=0.34). Almost half-of-patients (n=284,58%) demonstrated high AMI-knowledge. High-knowledge were independently associated with male-gender (OR=1.47[1.17-1.85]) and General-Practitioner as a knowledge-source (OR=1.42[1.14-1.77]). Old-age (OR=0.87[0.86-0.89]) and previous AMI-history/stent-placement (OR=0.65[0.46-0.93]) were significantly associated with lower-knowledge. Although the majority (476,98%) correctly recognized at least one AMI-symptom, 69(14.2%) patients correctly identified all AMI-symptoms. Additionally, one-in-three believed that heart-attack is always accompanied with severe chest-pain. Elderly-patients and women were more likely to be less-knowledgeable about atypical-symptoms (p=0.006), present with atypical AMI-presentation (p<0.001) and subsequently experience protracted delay-times (p<0.001).

CONCLUSIONS

Knowledge of AMI-symptoms remains to be substandard, especially knowledge of atypical-symptoms. Knowledge is essential to reduce delay-times, but it is not a panacea, since it is not sufficient alone to optimize prehospital delay-times.

Barriers to timely treatment-seeking in patients with acute myocardial infarction in Malaysia: a qualitative study

Background

Persisting delay in seeking treatment among Acute Myocardial Infarction (AMI) patients was reported in Malaysia despite intensified efforts in educating the public on symptoms of AMI and the importance of seeking prompt treatment. Studies outside Malaysia have shown that patients’ personal thoughts during symptom onset could contribute to the delay. The purpose of this study is to explore the barriers of AMI patients prior to the decision of seeking treatment in Malaysia.

Methods

A qualitative descriptive research approach was chosen. Individual in-depth interviews were conducted among 18 patients with AMI. Data were analysed using thematic analysis. Recordings were transcribed and coded, codes were subsequently organized into categories. The stages of coding and identifying categories were repeated before themes were identified.

Results

Three meaningful themes with nine sub-themes that may have influenced the delayed decision to seek treatment were identified. Some themes identified were culturally bound.

Conclusions

The findings of this study give insights on barriers prior to the decision of seeking treatment when patients were experiencing AMI. Findings indicates that interventions targeted at increasing knowledge about AMI symptoms and correct actions using an informative approach at the current practice may not be adequate to reduce patient delay. The findings of this study could provide basis for the development of interventions that are culturally relevant to the Malaysians setting to promote behavioural change in the population and reduce pre-hospital delay.

Cardiovascular health knowledge and preventive practices in people living with HIV in Kenya

BACKGROUND

Traditional cardiovascular disease (CVD) risk factors contribute to increase risk of CVD in people living with HIV (PLWH). Of all world regions, sub-Saharan Africa has the highest prevalence of HIV yet little is known about PLWH's CVD knowledge and self- perceived risk for coronary heart disease (CHD). In this study, we assessed PLWH's knowledge, perception and attitude towards cardiovascular diseases and their prevention.

METHODS

We conducted a cross-sectional study in the largest HIV care program in western Kenya. Trained research assistants used validated questionnaires to assess CVD risk patterns. We used logistic regression analysis to identify associations between knowledge with demographic variables, HIV disease characteristics, and individuals CVD risk patterns.

RESULTS

There were 300 participants in the study; median age (IQR) was 40 (33-46) years and 64 % women. The prevalence of dyslipidemia, overweight and obesity were 70 %, 33 % and 8 %, respectively. Participant's knowledge of risk factors was low with a mean (SD) score of 1.3 (1.3) out of possible 10. Most (77.7 %) could not identify any warning signs for heart attack. Higher education was a strong predictor of CVD risk knowledge (6.72, 95 % CI 1.98-22.84, P < 0.0001). Self-risk perception towards CHD was low (31 %) and majority had inappropriate attitude towards CVD risk reduction.

CONCLUSION

Despite a high burden of cardiovascular risk factors, PLWH in Kenya lack CVD knowledge and do not perceived themselves at risk for CHD. These results emphasis the need for behavior changes interventions to address the stigma and promote positive health behaviors among the high risk HIV population in Kenya.

The Process of Care-seeking for Myocardial Infarction Among Patients With Diabetes

BACKGROUND

People with diabetes have a higher risk for myocardial infarction (MI) than do people without diabetes. It is extremely important that patients with MI seek medical care as soon as possible after symptom onset because the shorter the time from symptom onset to treatment, the better the prognosis.

OBJECTIVE

The aim of this study was to explore how people with diabetes experience the onset of MI and how they decide to seek care.

METHODS

We interviewed 15 patients with diabetes, 7 men and 8 women, seeking care for MI. They were interviewed 1 to 5 days after their admission to hospital. Five of the participants had had a previous MI; 5 were being treated with insulin; 5, with a combination of insulin and oral antidiabetic agents; and 5, with oral agents only. Data were analyzed according to grounded theory.

RESULTS

The core category that emerged, "becoming ready to act," incorporated the related categories of perceiving symptoms, becoming aware of illness, feeling endangered, and acting on illness experience. Our results suggest that responses in each of the categories affect the care-seeking process and could be barriers or facilitators in timely care-seeking. Many participants did not see themselves as susceptible to MI and MI was not expressed as a complication of diabetes.

CONCLUSIONS

Patients with diabetes engaged in a complex care-seeking process, including several delaying barriers, when they experienced symptoms of an MI. Education for patients with diabetes should include discussions about their increased risk of MI, the range of individual variation in symptoms and onset of MI, and the best course of action when possible symptoms of MI occur.

Pre hospital indicators in assessing the quality of care for patients with acute coronary syndrome

Objective: to assess quality indicators related to the pre-hospital time for patients with acute coronary syndrome.Method: collection took place at a tertiary hospital in Paraná between 2012 and 2013, through interviews and a medical record review. 94 patients participated, 52.1% male, 78.7% who were over 50 years old, 46.9% studied until the fourth grade, 60.6% were diagnosed with acute myocardial infarction.Results: the outcomes were the time between the onset of symptoms and the decision to seek help with an average of 1022min ± 343.13, door-to-door 805min ± 181.78; and reperfusion, 455min ± 364.8. The choice to seek out care within 60 min occurred in patients who were having a heart attack, and longer than 60 min in those with a history of heart attack or prior catheterization.Conclusion: We concluded that the pre-hospital indicators studied interfered with the quality of care.

Mass Media Campaigns' Influence on Prehospital Behavior for Acute Coronary Syndromes: An Evaluation of the Australian Heart Foundation's Warning Signs Campaign

Background

The aim of this study was to examine the awareness of a recent mass media campaign, and its influence on knowledge and prehospital times, in a cohort of acute coronary syndrome (ACS) patients admitted to an Australian hospital.

Methods and Results

We conducted 199 semistructured interviews with consecutive ACS patients who were aged 35 to 75 years, competent to provide consent, and English speaking. Questions addressed the factors known to predict prehospital delay, awareness of the campaign, and whether it increased knowledge and influenced actions. Multivariable logistic regression was used to examine the association between campaign awareness and a 1-hour delay in deciding to seek medical attention (patient delay) and a 2-hour delay in presenting to hospital (prehospital delay). The median age was 62 years (IQR=53 to 68 years), and 68% (n=136) were male. Awareness of the campaign was reported by 127 (64%) patients, with most of these patients stating the campaign (1) increased their understanding of what is a heart attack (63%), (2) increased their awareness of the signs and symptoms of heart attack (68%), and (3) influenced their actions in response to symptoms (43%). After adjustment for other predictors, awareness of the campaign was significantly associated with patient delay time of ≤1 hour (adjusted odds ratio [AOR]=2.25, 95% CI: 1.03 to 4.91, P=0.04) and prehospital delay time ≤2 hours (AOR=3.11, 95% CI: 1.36 to 7.08, P=0.007).

Conclusions

Our study showed reasonably high awareness of the warning signs campaign, which was significantly associated with shorter prehospital decision-making and faster presentation to hospital.

Pre-hospital delay in acute myocardial infarction: judgement of symptoms and resistance to pain

OBJECTIVE

To estimate the time of decision (TD) to look for medical care and the time of arrival (TA) at the health service for men (M) and women (W) suffering from acute myocardial infarction and to analyze the influence of the interpretation of pain and pain resistance behaviors during these times.

METHODS

This is an exploratory research, performed at the university hospital in Salvador/Bahia. 43 W and 54 M were interviewed. To study the dependence among sociodemographic and gender variables, the Fisher Exact Test was used. To analyze times, a geometric mean (GM) was used. In order to verify the association between the GM of TD and TA and the judgment of pain, and between the GM of TD and TA and the behavior of resistance to pain, as well as to test the time of interaction between the gender variable and other variables of interest, the robust regression model was used. The statistical significance adopted was 5%.

RESULTS

The GM of the TD for M was 1.13 h; for W, 0.74 h. The GM of the TA was 1.74 h for M and 1.47 h for W. Those who did not recognize the symptoms of AMI and presented behavior of resistance to pain had higher TD and TA, being the associations significant. Gender did not change the associations of interest.

CONCLUSION

The findings demonstrate the importance of health education aiming at the benefits of early treatment.

Public knowledge of cardiovascular disease and its risk factors in Kuwait: a cross-sectional survey

BACKGROUND

Cardiovascular disease (CVD) is estimated to cause 46% of all mortalities in Kuwait. To design effective primary and secondary prevention programs, an assessment of a population's prior CVD knowledge is of paramount importance. There is scarcity of data on the existing CVD knowledge among the general Kuwaiti population. Hence, this study was performed to assess the level of knowledge towards CVD types, warning symptoms of heart attack or stroke, and CVD risk factors. It also explored public views on the community pharmacists' role in CVD prevention and management.

METHODS

A descriptive cross-sectional survey was performed using a pretested self-administered questionnaire on a sample of 900 randomly selected Kuwaiti individuals. Descriptive and multivariate logistic regression analysis were used in data analysis.

RESULTS

The response rate was 90.7%. Respondents' knowledge about types of CVD, heart attack or stroke symptoms was low. Almost 60% of respondents did not know any type of CVD, and coronary heart disease was the commonest identified type (29.0%). Two-fifths of participants were not aware of any heart attack symptoms, and the most commonly known were chest pain (50.4%) and shortness of breath (48.0%). Approximately half of respondents did not recognize any stroke symptoms, and the most commonly recognized were 'confusion or trouble speaking' (36.4%) and 'numbness or weakness' (34.7%). Respondents' knowledge regarding CVD risk factors was moderate. The commonest factors identified by over four-fifths of participants were smoking, obesity, unhealthy diet and physical inactivity. In the multivariate logistic regression analysis, independent predictors of better level of CVD knowledge were females, age 50-59 years, high level of education, regular eating of healthy diet, and had a family history of CVD. Most of respondents only identified the role that pharmacists had to play is to help patients manage their medications, with a minimal role in other aspects of CVD prevention and management.

CONCLUSIONS

There are deficiencies in CVD knowledge among Kuwaiti population, which could turn into insufficient preventative behaviours and suboptimal patient outcomes. There is an apparent need to establish more wide-spread and effective educational interventions, which should be sensitive to the perceptions, attitudes, and abilities of targeted individuals.

Inconsistent measurement of acute coronary syndrome patients' pre-hospital delay in research: a review of the literature

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.

The effect of symptoms on prehospital delay time in patients with acute myocardial infarction

Objective

To improve time to treatment, the effects of acute myocardial infarction (AMI) symptoms on prehospital delay time (PDT) were investigated.

Methods

Patients with AMI completed a questionnaire on their AMI symptoms and their general knowledge of AMI symptoms.

Results

In total, 116 patients completed questionnaires. The mean PDT was 7.3 ± 2.4  h; the median PDT was 2.2 h. Each patient experienced a mean of 3.6 symptoms during their AMI. PDT was significantly shorter in the following groups: patients with chest compression pain/chest discomfort, profuse sweating or dyspnoea than in patients with other symptoms; patients presenting with typical rather than atypical symptoms; patients with pain scores >6 compared with scores ≤6; patients who were aware rather than unaware of AMI symptoms. Patients actually having AMI symptoms and patients being aware of AMI symptoms were inversely correlated with PDT. There was a linear relationship between pain scores and PDT.

Conclusion

Public awareness of AMI symptoms should be enhanced, in order to shorten PDT and improve AMI survival rates.

Comparison of self-care behaviors of heart failure patients in 15 countries worldwide

OBJECTIVE

Clinicians worldwide seek to educate and support heart failure patients to engage in self-care. We aimed to describe self-care behaviors of patients from 15 countries across three continents.

METHODS

Data on self-care were pooled from 5964 heart failure patients from the United States, Europe, Australasia and South America. Data on self-care were collected with the Self-care of Heart Failure Index or the European Heart Failure Self-care Behavior Scale.

RESULTS

In all the samples, most patients reported taking their medications as prescribed but exercise and weight monitoring were low. In 14 of the 22 samples, more than 50% of the patients reported low exercise levels. In 16 samples, less than half of the patients weighed themselves regularly, with large differences among the countries. Self-care with regard to receiving an annual flu shot and following a low sodium diet varied most across the countries.

CONCLUSION

Self-care behaviors are sub-optimal in heart failure patients and need to be improved worldwide.

PRACTICE IMPLICATIONS

Interventions that focus on specific self-care behaviors may be more effective than general educational programs. Changes in some health care systems and national policies are needed to support patients with heart failure to increase their self-care behavior.

Treatment-seeking delays in patients with acute myocardial infarction and use of the emergency medical service

OBJECTIVES

To investigate treatment-seeking delays in Chinese patients with acute myocardial infarction (AMI) and to compare sex differences in this behaviour.

METHODS

A descriptive cross-sectional study was undertaken in patients with AMI, admitted to one of three hospitals in Shanghai, China. A treatment-seeking behaviour questionnaire was administered to each patient within 48 h of hospital admission.

RESULTS

In total, 250 patients were included: 159 men and 91 women. The median time for patients with AMI to make a treatment-seeking decision was 130 min. Women took significantly longer to seek treatment than men (240 min versus 120 min). The majority of patients (70.8%) took >1 h to decide to seek treatment. The emergency medical service (EMS) was used by 77 (30.8%) of patients, and these patients had a significantly shorter prehospital delay time than those who transported themselves to hospital. Predictive factors for using the EMS were pain level and rating AMI symptoms as severe.

CONCLUSIONS

Chinese patients with AMI had a significant prehospital delay time and women took longer than men to seek treatment. Public awareness of the importance of seeking immediate medical assistance for AMI via the EMS needs to be increased in China.

Factors Affecting Decision Making in Hispanics Experiencing Myocardial Infarction

It was estimated that 785,000 new myocardial infarctions (MIs), 470,000 recurrent MIs, and 195,000 silent MIs will occur during 2010 in the United States. Cardiovascular disease, including heart disease and stroke, is the cause of death for 27% of Hispanic males and 31.5% of Hispanic females. There has been an increasing discrepancy between Hispanic knowledge in recognition of MI symptoms compared with non-Hispanic Whites. Only 5.6 % to 27.4 % of Hispanics know all MI symptoms and the need to immediately activate emergency medical services, compared with 11.9% to 45.8% of non-Hispanic Whites. The health belief model is used to explore the factors affecting decision making in Hispanics experiencing MI. Modifying factors explored include acculturation, language spoken, education, socioeconomic status, and access to health care. The results include recommendations for future research and clinical practice to assist in planning targeted interventions in Hispanic populations nationwide.

A review of interventions aimed at reducing pre-hospital delay time in acute coronary syndrome: what has worked and why?

BACKGROUND

Delay in seeking treatment for acute coronary syndrome (ACS) symptoms is a well recognised problem. While the factors that influence pre-hospital delay have been well researched, to date this information alone has been insufficient in altering delay behaviour.

AIM

This paper reports the results of a critical appraisal of previously tested interventions designed to reduce pre-hospital delay in seeking treatment for ACS symptoms.

METHODS

The search was confined to interventions published between 1986 and the present that were written in English and aimed at reducing pre-hospital delay time. The following databases were searched using keywords: Cumulative Index to Nursing and Allied Health Literature (CINAHL), Pubmed, Academic Search Premier, Ovid, Cochrane, British Nursing Index, and Google Scholar. A total of eight intervention studies were identified as relevant. This review was developed following a systematic comparative analysis of those eight studies.

RESULTS

Seven of the eight interventions were based on mass media campaigns. One campaign was targeted at individuals. All were aimed at raising ACS symptom awareness and/or increasing prompt action in the presence of symptoms. Only two studies reported a statistically significant reduction in pre-hospital delay time.

CONCLUSION

In response to concerns about prolonged pre-hospital delay time in ACS, interventions targeting the problem have been developed. The literature indicates that responses to symptoms depend on a variety of factors. In light of this, interventions should include the scope of factors that can potentially influence pre-hospital delay time and ideally target those who are at greatest risk of an ACS event.

Women's Experiences and Behaviour at Onset of Symptoms of ST Segment Elevation Acute Myocardial Infarction

Background: Minimizing time from onset of symptoms to treatment (treatment delay) is crucial for patients with ST segment elevation acute myocardial infarction (STEMI), and one of the great challenges is to reduce the delay relating to the prehospital behaviour of the patient (patient delay). Studies indicate that women delay longer than men and insights into this area could lead to improved health education programmes aimed at reducing patient delay in women with STEMI.

Method: Open interviews with 14 women with STEMI were held during their hospital stay from June to September 2009. The interviews were aimed at exploring determinants of treatment delay, and were carried out and analysed within a phenomenological framework.

Findings: Three themes emerged important for the delay in seeking medical assistance: (1) Knowledge and ideas of AMI symptoms and risks. (2) Ambivalence whether to call for medical assistance or to cope with the situation. (3) Actions and strategies taken after onset of symptoms.

Conclusions: Three factors determined whether women showed appropriate behaviour for reduced patient delay after onset of symptoms: (1) identifying the symptoms as being of cardiac origin, (2) having a prepared action plan in case of an emergency situation, and (3) living with someone or contacting other persons.

Delays in presentation with acute coronary syndrome in people with coronary artery disease in Australia and New Zealand

OBJECTIVES

To report time from the onset of symptoms to hospital presentation in Australian and New Zealand patients with subsequently confirmed acute coronary syndrome, and to identify factors associated with prehospital delay time in these patients.

METHODS

Patients with coronary artery disease enrolled in a randomized clinical trial testing an intervention to reduce delay in responding to acute coronary syndrome symptoms had been followed for 24 months. In cases of admission to the ED for possible acute coronary syndrome, medical records were reviewed to determine the diagnosis, prehospital delay time, mode of transport to the hospital and aspirin use before admission. Clinical and demographic data were taken from the trial database.

RESULTS

Patients (n= 140) had an average (SD) age of 67.3 (11.5) years; 36% were female. Two-thirds of patients went to hospital by ambulance and 89.3% had a final diagnosis of unstable angina. The median time from onset of symptoms to arrival at the ED was 2 h and 25 min (interquartile range 1:25-4:59); 12.1% arrived ≤ 1 h and 66% within 4 h. Multiple linear regression analysis showed that use of ambulance (Beta = 0.247, P= 0.012) and younger age (Beta = 0.198, P= 0.043) were independent predictors of shorter delay times.

CONCLUSION

The time from the onset of symptoms to hospital presentation was too long for maximal benefit from treatment in most patients. Further efforts are needed to reduce treatment-seeking delay in response to symptoms of acute coronary syndrome.

Sex and age specific time patterns and long term time trends of pre-hospital delay of patients presenting with acute ST-segment elevation myocardial infarction

BACKGROUND

Prompt initiation of treatment after symptom onset of ST-elevation myocardial infarction (STEMI) is a central goal in limiting myocardial damage because of the time-dependent nature of reperfusion therapies. We examined time patterns and long term time trends of pre-hospital delay time (PHDT) of STEMI patients.

METHODS

PHDT from 3093 STEMI patients derived from the Augsburg Myocardial Infarction Registry (1985-2004) surviving >24h after admission was obtained by a standardized bedside interview. Patients with in-hospital MI (n=140) and resuscitation (n=157) were excluded. Linear regression models were used to examine monthly median PHDT and individual PHDT over time.

RESULTS

Female sex was associated with longer PHDT (189 (98-542quartiles) min vs. 154 (85-497) min; p<0.0003). Median PHDT in the youngest male subgroup (25-54 years) was 128 (73-458) min and mounted to 205 (107-600) min in the oldest female subgroup (65-74 years). A minority of 12.4% of patients reached hospital within 1h of delay ranging from 8.7% (in oldest women) to 15.9% (in youngest men). The age-adjusted linear regression model for monthly PHDT revealed no significant change over 20-year time in both sexes. The corresponding average annual percentage change estimates were -0.45 (95% CI: -1.40 to 0.54) for men and -0.08 (95% CI: -1.80 to 1.67) for women. Emergency ambulance use increased over time, however transportation time remained stable.

CONCLUSIONS

PHDT in STEMI patients is constantly high over a 20-year observation period. Room for improvement especially in older women was evidenced. Preventive strategies with focused efforts on this subgroup are warranted.

Predictors of pre-hospital delay among patients with acute myocardial infarction

OBJECTIVE

To evaluate current literature on predictors of pre-hospital delay among patients with acute myocardial infarction (AMI).

METHODS

Medline, CINHAL, and Psych Info databases were searched using keywords: attitude to illness/health, health beliefs, help/health seeking behavior, health behavior, psychosocial factors, treatment delay, socioeconomic factors, time factors, pre-hospital delay, and symptoms. These keywords were combined with AMI to identify literature published during 1995-2008.

RESULTS

Twenty-six data-based research articles were identified. Delay varied across literature and median pre-hospital delay was often reported due to distribution skewness resulting from extremely prolonged values (1.5-15.2h). Six categories of predictors influenced pre-hospital delay; socio-demographic, symptom onset context, cognitive, affective/psychological, behavioral, and clinical factors. Pre-hospital delay was shortest when the decision to seek healthcare was facilitated by family members or coworkers and when symptoms suggestive of heart attack were continuous and severe.

CONCLUSION AND PRACTICE IMPLICATIONS

Developing interventions programs to reduce pre-hospital delay for high-risk patients is warranted. Because decision delay is the only modifiable part by intervention, it is recommended that future investigations and interventions attend to decision time as the primary variable of interest instead of combining it with transportation time. Moreover, content of patient education need to emphasize on symptom awareness and recognition, and prompt and proper patient actions for optimum results. Also, in order to eliminate sampling bias resulting from investigating surviving AMI patients, it is recommended that future studies incorporate data from both surviving and surrogates of non-surviving AMI patients.
