Global review of delay time in seeking medical care for chest pain: An integrative literature review

OBJECTIVES The aim of this review is to summarise research from a range of countries describing the differences in time taken to seek medical care for chest pain and factors which contribute to delay times. METHODS An integrative literature review was undertaken using the Medline, CINAHL and Scopus databases for publications between 1994 and 2014. Articles dealing with delay time, and the factors associated with delay time, were extracted from the literature. RESULTS The search yielded 395 articles of which 205 full-text articles were assessed for eligibility. Finally, twenty-three articles met the inclusion criteria for the review. It was found that time to seeking treatment (delay times) varied between countries, ranging from 1.6 to 12.9h, with a mean of 3.4h. The mean delay times reported in all the selected studies were greater than the recommended time-frame for seeking treatment. As well, time to decision to seek treatment (decision time) was reported as a major component of delay time. Meanwhile, the utilisation rates of ambulance services ranged from 3.1% in Brazil to 61.0% in Australia. A majority of the reviewed studies reported on the factors associated with longer delay times, including old age, female gender, ethnicity, low education level, history of chronic disease, lack of knowledge of the symptoms, and underutilisation of ambulance services. Only three studies included a sub-analysis by ethnicity, reporting that ethnic groups had longer delay times than Caucasians. CONCLUSION Variability in delay times occurred across countries and within continents. The mean time taken to seek care for chest pain in the countries reviewed did not meet the recommended times according to international guidelines. Demographic and social factors, as well as cognitive and emotional factors, influenced delay times. Further research on these influencing factors is recommended, including the impact of ethnicity on patients care-seeking behaviours for chest pain.

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

BackgroundAcute 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. ObjectivesThe 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 participantsPatients from different ethnic minority groups presenting to emergency departments (EDs) with chest pain. Types of exposureThe 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 studiesThe 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. OutcomesThe 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 strategyA 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 qualityPapers 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 extractionData were extracted from included articles by two independent reviewers using the standardized data extraction tool from the Joanna Briggs Institute. Data synthesisThe 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. ResultsA 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. ConclusionThere 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.

Is there inequity in hospital care among patients with acute coronary syndrome who are proficient and not proficient in English language? Analysis of the SNAPSHOT ACS study

Background: The provision of equitable acute coronary syndrome (ACS) care in Australia and New Zealand requires an understanding of the sources of variation in the provision of this care. Objective: The aim of this study was to compare the variation in care and outcomes between ACS patients with limited English proficiency (LEP) and English proficiency (EP) admitted to Australian and NZ hospitals. Methods: Data were collected from 4387 suspected/confirmed ACS patients from 286 hospitals between May 14 and 27, 2012, who were followed for 18 months. We compared hospital care and outcomes according to the proficiency of English using logistic regressions. Results: The 294 LEP patients were older (70.9 vs 66.3 years; P < .001) and had higher prevalence of hypertension (71.1% vs 62.8%; P = .004), diabetes (40.5% vs 24.3%; P < .001), and renal impairment (16.3% vs 11.1%; P = .007) compared with the 4093 EP patients. Once in hospital, there was no difference in receipt of percutaneous coronary intervention (57.0% vs 55.4%; P = .78) or coronary artery bypass graft surgery (10.5% vs 11.5%; P = .98). After adjustment for medical history, there were no significant differences (P > .05) between the 2 groups in the risk of major adverse cardiovascular events and/or all-cause death during the index admission and from index admission to 18 months. Conclusions: These results suggest that LEP patients admitted to Australian or New Zealand hospitals with suspected ACS may not experience inequity in hospital care and outcomes.

Presenting characteristics and processing times for culturally and linguistically diverse (CALD) patients with chest pain in an emergency department: Time, Ethnicity, and Delay (TED) Study II

BACKGROUND To date there has been limited published data presenting the characteristics and timeliness of the management in an Emergency Department (ED) for culturally and linguistically diverse (CALD) patients presenting with chest pain. This study aimed to describe the presenting characteristics and processing times for CALD patients with chest pain compared to the Australian-born population, and current guidelines. METHODS This study was a cross sectional analysis of a cohort of patients who presented with chest pain to the metropolitan hospital between 1 July 2012 and 30 June 2014. RESULTS Of the total study population (n=6640), 1241 (18.7%) were CALD and 5399 (81.3%) were Australian-born. CALD patients were significantly older than Australian-born patients (mean age 62 vs 56years, p<0.001). There were no differences in the proportion of patients who had central chest pain (74.9% vs 75.7%, p=0.526); ambulance utilisation (41.7% vs 41.1%, p=0.697); and time to initial treatment in ED (21 vs 22min, p=0.375). However, CALD patients spent a significantly longer total time in ED (5.4 vs 4.3h, p<0.001). There was no difference in guideline concordance between the two groups with low rates of 12.5% vs 13%, p=0.556. Nonetheless, CALD patients were 22% (95% CI, 0.65, 0.95, p=0.015) less likely to receive the guideline management for chest pain. CONCLUSIONS The initial emergency care was equally provided to all patients in the context of a low rate of concordance with three chest pain related standards from the two guidelines. Nonetheless, CALD patients spent a longer time in ED compared to the Australian-born group.
