Lay diagnosis and health-care-seeking behaviour for chest pain in south Asians and Europeans

Ethnicity and outcomes for patients with gastrointestinal disorders attending an emergency department serving a multi-ethnic population

BACKGROUND

Ethnic inequalities in acute health acute care are not well researched. We examined how attendee ethnicity influenced outcomes of emergency care in unselected patients presenting with a gastrointestinal (GI) disorder.

METHODS

A descriptive, retrospective cohort analysis of anonymised patient level data for University Hospitals of Leicester emergency department attendees, from 1 January 2018 to 31 December 2021, receiving a diagnosis of a GI disorder was performed. The primary exposure of interest was self-reported ethnicity, and the two outcomes studied were admission to hospital and whether patients underwent clinical investigations. Confounding variables including sex and age, deprivation index and illness acuity were adjusted for in the analysis. Chi-squared and Kruskal-Wallis tests were used to examine ethnic differences across outcome measures and covariates. Multivariable logistic regression was used to examine associations between ethnicity and outcome measures.

RESULTS

Of 34,337 individuals, median age 43 years, identified as attending the ED with a GI disorder, 68.6% were White. Minority ethnic patients were significantly younger than White patients. Multiple emergency department attendance rates were similar for all ethnicities (overall 18.3%). White patients had the highest median number of investigations (6, IQR 3-7), whereas those from mixed ethnic groups had the lowest (2, IQR 0-6). After adjustment for age, sex, year of attendance, index of multiple deprivation and illness acuity, all ethnic minority groups remained significantly less likely to be investigated for their presenting illness compared to White patients (Asian: aOR 0.80, 95% CI 0.74-0.87; Black: 0.67, 95% CI 0.58-0.79; mixed: 0.71, 95% CI 0.59-0.86; other: 0.79, 95% CI 0.67-0.93; p < 0.0001 for all). Similarly, after adjustment, minority ethnic attendees were also significantly less likely to be admitted to hospital (Asian: aOR 0.63, 95% CI 0.60-0.67; Black: 0.60, 95% CI 0.54-0.68; mixed: 0.60, 95% CI 0.51-0.71; other: 0.61, 95% CI 0.54-0.69; p < 0.0001 for all).

CONCLUSIONS

Significant differences in usage patterns and disparities in acute care outcomes for patients of different ethnicities with GI disorders were observed in this study. These differences persisted after adjustment both for confounders and for measures of deprivation and illness acuity and indicate that minority ethnic individuals are less likely to be investigated or admitted to hospital than White patients.

Rates of knee arthroplasty in patients with a history of arthroscopic chondroplasty: results from a retrospective cohort study utilising the National Hospital Episode Statistics for England

OBJECTIVE

The purpose of this study was to analyse the rate of knee arthroplasty in the population of patients with a history of arthroscopic chondroplasty of the knee, in England, over 10 years, with comparison to general population data for patients without a history of chondroplasty.

DESIGN

Retrospective cohort study.

SETTING

English Hospital Episode Statistics (HES) data.

PARTICIPANTS AND INTERVENTIONS

Patients undergoing arthroscopic chondroplasty in England between 2007/2008 and 2016/2017 were identified. Patients undergoing previous arthroscopic knee surgery or simultaneous cruciate ligament reconstruction or microfracture in the same knee were excluded.

OUTCOMES

Patients subsequently undergoing a knee arthroplasty in the same knee were identified and mortality-adjusted survival analysis was performed (survival without undergoing knee arthroplasty). A Cox proportional hazards model was used to identify factors associated with knee arthroplasty. Relative risk of knee arthroplasty (total or partial) in comparison to the general population was determined.

RESULTS

Through 2007 to 2017, 157 730 eligible chondroplasty patients were identified. Within 1 year, 5.91% (7984/135 197; 95% CI 5.78 to 6.03) underwent knee arthroplasty and 14.22% (8145/57 267; 95% CI 13.94 to 14.51) within 5 years. Patients aged over 30 years with a history of chondroplasty were 17.32 times (risk ratio; 95% CI 16.81 to 17.84) more likely to undergo arthroplasty than the general population without a history of chondroplasty.

CONCLUSIONS

Patients with cartilage lesions of the knee, treated with arthroscopic chondroplasty, are at greater risk of subsequent knee arthroplasty than the general population and for a proportion of patients, there is insufficient benefit to prevent the need for knee arthroplasty within 1 to 5 years. These important new data will inform patients of the anticipated outcomes following this procedure. The risk in comparison to non-operative treatment remains unknown and there is an urgent need for a randomised clinical trial in this population.

Rates of knee arthroplasty within one-year of undergoing arthroscopic partial meniscectomy in England: temporal trends, regional and age-group variation in conversion rates

OBJECTIVE

The aim of this study was to determine the proportion of patients undergoing arthroscopic partial meniscectomy (APM) then subsequently receiving a knee arthroplasty within one or two years, with focus on patients over the age of 60 years and regional variation.

METHODS

Patients undergoing APM in England over 20-years (01-April-1997 to 31-March 2017) were identified in the national Hospital Episode Statistics (HES). The proportion of patients undergoing arthroplasty in the same knee within one or two years of APM was determined and trends were analysed over time nationally and by NHS Clinical Commissioning Group (CCG) region.

RESULTS

806,195 APM patients were eligible for analysis with at least one-year of follow up and 746,630 with two-years. The odds of arthroplasty conversion within one year increased over the study period (odds ratio [OR] 3.10 within 1-year in 2014 vs 2000; 95% confidence interval [CI] 2.75-3.50). For patients undergoing APM aged 60 years or older in 2015-16, 9.9% (1689/17,043; 95% CI 9.5-10.4) underwent arthroplasty within 1-year and, in 2014-15, 16.6% (3100/18,734; 95% CI 16.0-17.1) underwent arthroplasty within 2-years. There was greater than 10-fold variation by CCG.

CONCLUSIONS

Over the study period, the proportion of patients undergoing arthroplasty within one-year of APM increased. In 2015-16, of patients aged 60 years or older who underwent APM, 10% subsequently underwent knee arthroplasty within one year (17% within two years in 2014-15) and there was a high level of regional variation in this outcome. The development and adoption of national treatment guidance is recommended to improve and standardise treatment selection.

Long-term rates of knee arthroplasty in a cohort of 834 393 patients with a history of arthroscopic partial meniscectomy

Aims

The aim of this study was to determine the long-term risk of undergoing knee arthroplasty in a cohort of patients with meniscal tears who had undergone arthroscopic partial meniscectomy (APM).

Patients and Methods

A retrospective national cohort of patients with a history of isolated APM was identified over a 20-year period. Patients with prior surgery to the same knee were excluded. The primary outcome was knee arthroplasty. Hazard ratios (HRs) were adjusted by patient age, sex, year of APM, Charlson comorbidity index, regional deprivation, rurality, and ethnicity. Risk of arthroplasty in the index knee was compared with the patient’s contralateral knee (with vs without a history of APM). A total of 834 393 patients were included (mean age 50 years; 37% female).

Results

Of those with at least 15 years of follow-up, 13.49% (16 256/120 493; 95% confidence interval (CI) 13.30 to 13.69) underwent subsequent arthroplasty within this time. In women, 22.07% (95% CI 21.64 to 22.51) underwent arthroplasty within 15 years compared with 9.91% of men (95% CI 9.71 to 10.12), corresponding to a risk ratio (RR) of 2.23 (95% CI 2.16 to 2.29). Relative to the general population, patients with a history of APM were over ten times more likely (RR 10.27; 95% CI 10.07 to 10.47) to undergo arthroplasty rising to almost 40 times more likely (RR 39.62; 95% CI 27.68 to 56.70) at a younger age (30 to 39 years). In patients with a history of APM in only one knee, the risk of arthroplasty in that knee was greatly elevated in comparison with the contralateral knee (no APM; HR 2.99; 95% CI 2.95 to 3.02).

Conclusion

Patients developing a meniscal tear undergoing APM are at greater risk of knee arthroplasty than the general population. This risk is three-times greater in the patient’s affected knee than in the contralateral knee. Women in the cohort were at double the risk of progressing to knee arthroplasty compared with men. These important new reference data will inform shared decision making and enhance approaches to treatment, prevention, and clinical surveillance.

Perceptions of chest pain and healthcare seeking behavior for chest pain in northern Tanzania: A community-based survey

Background

Little is known about community perceptions of chest pain and healthcare seeking behavior for chest pain in sub-Saharan Africa.

Methods

A two-stage randomized population-based cluster survey with selection proportional to population size was performed in northern Tanzania. Self-identified household healthcare decision-makers from randomly selected households were asked to list all possible causes of chest pain in an adult and asked where they would go if an adult household member had chest pain.

Results

Of 718 respondents, 485 (67.5%) were females. The most commonly cited causes of chest pain were weather and exercise, identified by 342 (47.6%) and 318 (44.3%) respondents. Two (0.3%) respondents identified ‘heart attack’ as a possible cause of chest pain. A hospital was selected as the preferred healthcare facility for an adult with chest pain by 277 (38.6%) respondents. Females were less likely to prefer a hospital than males (OR 0.65, 95% CI 0.47–0.90, p = 0.008).

Conclusions

There is little community awareness of cardiac causes of chest pain in northern Tanzania, and most adults reported that they would not present to a hospital for this symptom. There is an urgent need for educational interventions to address this knowledge deficit and guide appropriate care-seeking behavior.

A cross-sectional study of ethnicity-based differences in treatment seeking for symptoms of acute coronary syndrome

BACKGROUND

Patient-related delays in acquiring medical care for symptoms of acute coronary syndrome remain unacceptably long. Many clinical and sociodemographic characteristics associated with treatment-seeking delay are known; however, ethnicity has not been extensively evaluated.

OBJECTIVE

The purpose of this study was to examine ethnicity-based differences in the time-to-treatment-seeking intervals of patients experiencing symptoms of acute coronary syndrome.

METHOD

Data for this descriptive study were collected for the larger Acute Coronary Syndrome Care in Emergency Departments (ASCEND) study. The larger study is a prospective, observational study in which patients presenting to hospital emergency departments and triaged as having symptoms suggestive of acute coronary syndrome are identified. The primary outcome of this study, the time-to-treatment-seeking interval, was defined as the time between symptom onset and treatment seeking. The predictor variable, ethnicity, was measured with self-reported data and categorised as Chinese, South Asian, or 'Other' ethnic group. Participants in the 'Other' ethnic group were predominantly of European ancestry. Univariate and multivariate analyses were undertaken, along with nonparametric testing.

RESULTS

The study sample consisted of 419 participants: 36 Chinese, 126 South Asian, and 257 'Other' participants. The median time-to-treatment-seeking interval, for the total sample, was 180 minutes. A Kruskal-Wallis test demonstrated no statistically significant differences in the time-to-treatment-seeking intervals by ethnicity.

CONCLUSION

No ethnicity-based differences in the time-to-treatment-seeking intervals for symptoms of acute coronary syndrome were found. It is possible that Chinese and South Asian patients living in western countries are more aware of the potential signs and symptoms of acute coronary syndrome or feel more confident to access healthcare services than they have been previously.

Inequity in Recording of Risk in a Local Population-Based Screening Programme for Cardiovascular Disease

Background

Screening for cardiovascular disease is an important primary preventive measure, yet research has documented that not all population groups receive the same quality of preventive healthcare.

Design

Longitudinal analysis of cardiovascular disease risk factor recording.

Methods

Data were made available from a local population-based screening programme for cardiovascular disease (1989-1999), whereby residents aged 35-60 years were invited for screening every 5 years (n = 84 646). Data were recorded for major risk factors including blood pressure, cholesterol, body mass index, smoking status, and alcohol consumption. Completeness of risk factor recording was compared between groups in the screened population defined by gender, ethnicity (Caucasian/South Asian) and employment status (employed/unemployed).

Results

Recording of risk in the screened population was significantly less complete for women and South Asian participants over the duration of the screening programme, compared with men and Caucasian participants respectively. Conversely, recording of risk was significantly more complete for the unemployed compared with the employed participants.

Conclusions

These findings present evidence of a less systematic screening procedure for women and South Asians, whilst it seems that men, Caucasian participants and the unemployed were appropriately screened. Inequalities at the primary preventive level will likely influence outcome, because equitable identification of risk is important for the provision of successful treatment measures, and to reduce inequalities in morbidity and mortality due to cardiovascular disease.

Age-related references in national public health, technology appraisal and clinical guidelines and guidance: documentary analysis

Background

older people may be less likely to receive interventions than younger people. Age bias in national guidance may influence entire public health and health care systems. We examined how English National Institute for Health & Care Excellence (NICE) guidance and guidelines consider age.

Methods

we undertook a documentary analysis of NICE public health (n = 33) and clinical (n = 114) guidelines and technology appraisals (n = 212). We systematically searched for age-related terms, and conducted thematic analysis of the paragraphs in which these occurred (‘age-extracts’). Quantitative analysis explored frequency of age-extracts between and within document types. Illustrative quotes were used to elaborate and explain quantitative findings.

Results

2,314 age-extracts were identified within three themes: age documented as an a-priori consideration at scope-setting (518 age-extracts, 22.4%); documentation of differential effectiveness, cost-effectiveness or other outcomes by age (937 age-extracts, 40.5%); and documentation of age-specific recommendations (859 age-extracts, 37.1%). Public health guidelines considered age most comprehensively. There were clear examples of older-age being considered in both evidence searching and in making recommendations, suggesting that this can be achieved within current processes.

Conclusions

we found inconsistencies in how age is considered in NICE guidance and guidelines. More effort may be required to ensure age is consistently considered. Future NICE committees should search for and document evidence of age-related differences in receipt of interventions. Where evidence relating to effectiveness and cost-effectiveness in older populations is available, more explicit age-related recommendations should be made. Where there is a lack of evidence, it should be stated what new research is needed.

The Experiences and Needs of Gujarati Hindu Patients and Partners in the First Month after a Myocardial Infarction

BACKGROUND

South Asian people living in the United Kingdom are at increased risk of coronary heart disease, have higher mortality rates and are less likely to be treated when compared to the white population. There is, however, little information about the experiences and needs of this group after discharge from hospital.

AIMS

To explore the experiences and needs of Gujarati Hindu patients and their partners in the first month after a myocardial infarction.

METHODS

Using a qualitative research approach, semi-structured interviews were conducted by a Gujarati-speaking researcher with 35 patients and their partners at home during early convalescence.

RESULTS

A number of categories emerged from the data which pertained to a lack of information and advice, poor performance of activity, little lifestyle adjustment, poor expectations, lack of future plans, strong family support, dissatisfaction with the family doctor, and a significant belief in fate.

CONCLUSION

Experiences and health care needs of Gujarati Hindu patients with myocardial infarction appear different to those of non-Asians. Cardiac aftercare and rehabilitation services should take account of such information

Ethnicity and pre-hospital care for people with suspected cardiac pain: cross-sectional study

OBJECTIVES

Few studies have investigated the quality of pre-hospital care by ethnicity. We aimed to investigate ethnic differences in pre-hospital ambulance care of patients with suspected cardiac pain.

METHODS

We conducted a cross-sectional analysis of retrospective electronic clinical data for patients with suspected cardiac pain over one year (August 2011 to July 2012) extracted from a single regional ambulance service. This included patient demographic data, clinical measurements, drugs administered and outcomes, such as transportation to hospital or referral to primary care. We used multivariate regression to investigate differences in care by ethnicity comparing non-White with White patients.

RESULTS

There were 7046 patients with suspected cardiac pain, with 4825 who had ethnicity recorded including 4661 (96.6%) White and 164 (3.4%) non-White. After correcting for age, sex, socio-economic status and whether transported to hospital, non-White patients were significantly more likely to have temperature [odds ratio (OR) 2.96, P = 0.007], blood glucose (OR 3.95, P = 0.003), respiratory rate (OR 4.94, P = 0.03) and oxygen saturation (OR 2.43, P = 0.006) recorded. Non-White patients were significantly less likely to be transported to hospital (OR 0.43, P = 0.03).

CONCLUSION

There were significant differences in pre-hospital ambulance care for non-White compared with White patients with suspected cardiac pain. These differences could be due to differences in clinical condition or case-mix, language and cultural barriers, limited understanding of appropriate use of health care services, recording bias or true differences in provider management. Further analysis should involve larger and more complete data sets to explore ethnic differences in greater detail.

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.

Association of smoking and concomitant metformin use with cardiovascular events and mortality in people newly diagnosed with type 2 diabetes

BACKGROUND

The cardiovascular and mortality risk in patients with incident type 2 diabetes (T2D) in relation to smoking status and concurrent use of metformin is not well known.

METHODS

A cohort study was performed in 82,205 incident T2D patients from the U.K. Clinical Practice Research Datalink. In the present study, the risks of myocardial infarction (MI), stroke, and mortality in incident T2D patients were evaluated in relation to their smoking status with and without concurrent use of metformin.

RESULTS

Over a median 5.4 years of follow-up, of patients without a history of cardiovascular disease (CVD) before a diagnosis of diabetes (n = 63,166), current smokers with and without metformin had an 8% (hazard ratio [HR] 1.08; 95% confidence interval [CI] 0.81, 1.45) and 32% (HR 1.32; 95% CI 1.07, 1.65) increased risk of MI or stroke, respectively, compared with non-smokers without metformin treatment. The respective HRs (95% CI) for mortality in these patients were 0.96 (0.83, 1.11) and 1.86 (1.68, 2.07). The HR for mortality among ex-smokers with and without concurrent metformin treatment was 0.92 (95% CI 0.83, 1.11) and 1.19 (95% CI 1.10, 1.30), respectively. Similar beneficial modifiable effects of metformin among ex- and current smokers were observed in patients with CVD before diagnosis of diabetes (n = 19,039).

CONCLUSIONS

In T2D patients, concurrent treatment with metformin attenuates the observed higher cardiovascular and mortality risk in ex- and current smokers. In addition to smoking cessation support, treatment with metformin, particularly in ex- and current smokers, should be encouraged.

Ethnicity and neighbourhood deprivation determines the response rate in sexual dysfunction surveys

BACKGROUND

Self-administered questionnaires provide a better alternative to disclose sensitive information in sexual health research. We describe the factors that determine the positive response (initial recruitment) to an initial invitation and subsequent completion of study to a postal questionnaire on sexual dysfunction.

METHODS

South Asians (SA) and Europids with and without diabetes (DM) were recruited from GP clinics in UK. Men who returned the properly filled consent form ('recruited-group') were sent the questionnaire and those who returned it were considered as the 'completed-group'. Index of Multiple Deprivation Scores (IMDs) were generated using UK postcodes. We calculated the recruitment rate and completion rate of the recruited and the study-completed groups respectively.

RESULTS

Total approached sample was 9100 [DM: 2914 (32%), SA: 4563 (50.1%)]. Recruitment rate was 8.8% and was higher in Europids and in patients with DM. Mean IMDs for the recruited group was 20.9 ± 11.9, and it was higher among recruited SA compared to Europids (p < 0.001). Mean IMDs was higher in the recruited group compared to non-recruited (p < 0.01). All four recruited groups (SA/Europid and DM/non-DM) had lower IMDs compared to non-recruited. Completion rate was 71.5% (n 544) (SA: 62.3%, Europids: 77.4%; p < 0.05).

CONCLUSION

Recruitment for postal sexual health surveys is positively influenced by presence of investigated disease, older age, being from lesser deprived areas and Europid ethnicity. Furthermore, Europids were more likely to complete survey than South Asians irrespective of disease status.

The first 12 weeks following discharge from hospital: The experience of Gujarati South Asian survivors of acute myocardial infarction and their families

The period following discharge from hospital after an acute myocardial infarction (MI) is associated with vulnerability and psychosocial and physical morbidity for many survivors and their families. It is reported that people experience interpersonal, family and financial problems, self-care obstacles, work and physical difficulties. Culture and ethnicity undeniably influence the illness experience and the process of recovery and adjustment. This study investigated the perceptions of Gujarati survivors of acute MI and their families in Leicester, United Kingdom in the first 12 weeks following discharge in order to develop a profile of their health seeking beliefs and needs. Thirty-one interviews with 19 Gujarati MI survivors and their families (representing approximately 31 hours of dialogue) were analysed using grounded theory. Qualitative data revealed a period of vulnerability not only for survivors but also their families as they processed recent events and faced the future. Data analysis revealed nine interrelated themes describing the post-discharge experience for Gujarati survivors and their families. Data revealed that normal life was often markedly changed by the MI experience. Reflection, contemplation and resignation characterize this period of vulnerability. Overwhelmingly, data analysis revealed that the Gujarati culture, beliefs and customs influenced the recovery experience.

Chest pain symptom scoring can improve the quality of referrals to Rapid Access Chest Pain Clinic

Typical stable angina is a clinical diagnosis based on history. The challenge for GPs in primary care is to identify those patients who are presenting with either possible or typical angina symptoms and refer onwards for specialist assessment in the local Rapid Access Chest Pain Clinic (RACPC). Our initial information gathering study suggested that referring GPs may be cautiously overdiagnosing angina in primary care, potentially resulting in avoidable or unnecessary referrals to RACPC. We sought a practical and cost effective solution to reducing avoidable referrals by assisting GPs with chest pain discrimination. We tested a change of referral form incorporating chest pain symptom scoring to see whether GP referral quality could be improved and then assessed its impact post implementation. GPs that used the chest pain symptom scoring questionnaire were more than twice as likely to correctly discriminate non-cardiac chest pain. Our post implementation study of the new referral form showed that the proportion of referrals to RACPC with diagnosis of non-cardiac chest pain reduced by almost 19%, and there was a statistically significant 30% fall in the total number of referrals to RACPC. This was likely to be driven by the deterrent effect of the novel referral form on avoidable referrals. Fewer avoidable referrals results in shorter wait times for specialist review, reduces the risk of waiting time breach, and improves RACPC efficiency. In summary, chest pain symptom scoring resulted in improved GP discrimination of chest pain, improved referral quality, fewer overall referrals to RACPC and shorter patient wait times. These benefits were achieved without using additional financial resources and without the time or capital expense of training GPs. These findings could assist GPs and Clinical Commisioning Groups to achieve cost savings by reducing avoidable secondary care referrals.

The influence of ethnicity and gender on navigating an acute coronary syndrome event

BACKGROUND

Ethnicity and gender may influence acute coronary syndrome patients recognizing symptoms and making the decision to seek care.

OBJECTIVE

To examine these potential differences in European (Caucasian), Chinese and South Asian acute coronary syndrome patients.

METHODS

In-depth interviews were conducted with 20 European (Caucasian: 10 men/10 women), 18 Chinese (10 men/eight women) and 19 South Asian (10 men/nine women) participants who were purposively sampled from those participating in a large cohort study focused on acute coronary syndrome. Analysis of transcribed interviews was undertaken using constant comparative methods.

RESULTS

Participants followed the process of: having symptoms; waiting/denying; justifying; disclosing/ discovering; acquiescing; taking action. The core category was 'navigating the experience'. Certain elements of this process were in the forefront, depending on participants' ethnicity and/or gender. For example, concerns regarding language barriers and being a burden to others varied by ethnicity. Women's tendency to feel responsibility to their home and family negatively impacted the timeliness in their decisions to seek care. Men tended to disclose their symptoms to receive help, whereas women often waited for their symptoms to be discovered by others. Finally, the thinking that symptoms were 'not-urgent' or something over which they had no control and concern regarding potential costs to others were more prominent for Chinese and South Asian participants.

CONCLUSION

Ethnic- and gender-based differences suggest that education and support, regarding navigation of acute coronary syndrome and access to care, be specifically targeted to ethnic communities.

Healthcare-seeking behaviour in rural Ethiopia: evidence from clinical vignettes

OBJECTIVES

To investigate the determinants of healthcare-seeking behaviour using five context-relevant clinical vignettes. The analysis deals with three issues: whether and where to seek modern care and when to seek care.

SETTING

This study is set in 96 villages located in four main regions of Ethiopia. The participants of this study are 1632 rural households comprising 9455 individuals.

PRIMARY AND SECONDARY OUTCOME MEASURES

Probability of seeking modern care for symptoms related to acute respiratory infections/pneumonia, diarrhoea, malaria, tetanus and tuberculosis. Conditional on choosing modern healthcare, where to seek care (health post, health centre, clinic and hospital). Conditional on choosing modern healthcare, when to seek care (seek care immediately, the next day, after 2 days, between 3 days to 1 week, a week or more).

RESULTS

We find almost universal preference for modern care. Foregone care ranges from 0.6% for diarrhoea to 2.5% for tetanus. There is a systematic relationship between socioeconomic status and choice of providers mainly for adult-related conditions with households in higher consumption quintiles more likely to seek care in health centres, private/Non-Government Organization (NGO) clinics as opposed to health posts. Delays in care-seeking behaviour are apparent mainly for adult-related conditions and among poorer households.

CONCLUSIONS

The analysis suggests that the lack of healthcare utilisation is not driven by the inability to recognise health problems or due to a low perceived need for modern care.

Ethnocentric approach to address South Asian health issues

South Asian populations have distinct healthcare requirements to other ethnic demographics. Epidemiologically they constitute a high-risk group for many public health diseases such as cardiovascular disease, chronic kidney disease and diabetes mellitus. Despite individuals of South Asian backgrounds encompassing many individual countries, cultures, religions and backgrounds they share many common health concerns that are poorly tackled in established models of healthcare delivery. To successfully address this burgeoning public health burden, it is important for healthcare professionals and providers to appreciate the need for an ethnocentric approach to South Asian health requirements. Key stakeholders need to understand the need for an integrated ethnocentric approach to challenge the poor health status of this population. Appreciation of the socio-cultural dimension to South Asian healthcare requirements should help guide targeted and focused strategies to improve the outlook for this unique population at high public health risk.

Integrating primary care and public health: learning from the Brazilian way

After a long history of vertical programming, specialisation and disintegration, general practitioners are now being urged to take on wider commissioning and public health responsibilities. The support structures are not in place, and integration of primary care with good public health practice is new territory. Innovation can be found in unlikely places. The Brazilian government has a 20-year history of a nationwide, integrated, comprehensive, community health programme that seamlessly bridges two important interfaces - between the community and primary care, and between primary care and public health. Some elements of this approach could be translated into the UK and would likely bring about improved clinical care, cost savings, improved understanding of local epidemiological variations and therefore commissioning. Understanding this approach is the first step to a new way of integrated commissioning, spanning and not reinforcing traditional clinical domains.

A registry-based follow-up study, comparing the incidence of cardiovascular disease in native Danes and immigrants born in Turkey, Pakistan and the former Yugoslavia: do social inequalities play a role?

Background

This study compared the incidence of cardiovascular disease (CVD) and acute myocardial infarction (AMI) between native Danes and immigrants born in Turkey, Pakistan and the former Yugoslavia. Furthermore, we examined whether different indicators of socioeconomic status (SES), such as employment, income and housing conditions influenced potential differences.

Methods

In this registry-based follow-up study individuals were identified in a large database that included individuals from two major regions in Denmark, corresponding to about 60% of the Danish population. Incident cases of CVD and AMI included fatal and non-fatal events and were taken from registries. Using Cox regression models, we estimated incidence rates at 5-year follow-up.

Results

Immigrant men and women from Turkey and Pakistan had an increased incidence of CVD, compared with native Danish men. In the case of AMI, a similar pattern was observed; however, differences were more pronounced. Pakistanis and Turks with a shorter duration of residence had a lower incidence, compared with those of a longer residence. Generally, no notable differences were observed between former Yugoslavians and native Danes. In men, differences in CVD and AMI were reduced after adjustment for SES, in particular, among Turks regarding CVD. In women, effects were particularly reduced among Yugoslavians in the case of CVD and in Turks in the case of CVD and AMI after adjustment for SES.

Conclusions

In conclusion, country of birth-related differences in the incidence of CVD and AMI were observed. At least some of the differences that we uncovered were results of a socioeconomic effect. Duration of residence also played a certain role. Future studies should collect and test different indicators of SES in studies of CVD among immigrants.

Response to a cardiac event in relation to cardiac knowledge and risk perception in a Lebanese sample: a cross sectional survey

BACKGROUND

Heart disease is the leading cause of morbidity and mortality in many countries, including Lebanon. The continuing advances in the treatment of heart disease have improved patient outcomes significantly over the years. Nevertheless, prompt treatment remains essential to treatment success, which depends on the person's early recognition of cardiac symptoms and quick seeking of care.

OBJECTIVE

The purpose of the study was to examine the relationship between knowledge of symptoms of heart disease, perceived cardiac risk and the potential response to a heart attack in a sample of Lebanese adults.

DESIGN

A cross sectional descriptive survey design was used. A convenience sample of 399 adult hospital visitors who did not have heart disease were interviewed in two major referral hospitals in Beirut.

MEASURES

The Illness Perception Questionnaire and the Behavioral Risk Factor Surveillance System were used; in addition an open-ended question was asked to elicit what the visitor would do in case he/she experienced cardiac symptoms.

RESULTS

While most participants (94%) correctly recognized major symptoms of heart disease (like chest pain and dyspnea), they also reported irrelevant symptoms to be associated with heart disease (like irritability by 68% and muscle cramps by 52%). Only 21% of participants reported that they would seek emergency care as their first response if they were experiencing a heart attack. Knowledge of symptoms and perceived cardiac risk were not associated with the response to a heart attack. Being single was the only significant predictor of choosing the appropriate response when experiencing a cardiac event.

CONCLUSION

The findings suggest lack of adequate knowledge of cardiac symptoms and a high potential for inappropriate responses when symptoms occur. Public health heart health campaigns are needed to raise awareness about heart disease in Lebanon.

Exploring the impact of patient views on 'appropriate' use of services and help seeking: a mixed method study

BACKGROUND

There are commonly-held views relating to what constitutes appropriate and inappropriate use of finite NHS resources. However, very little is known about how and why such views have an impact on consultation patterns.

AIM

To quantify the prevalence of opinion on whether people use health services unnecessarily within primary care and accident and emergency (A&E) in order to examine the impact of these views on help-seeking behaviour.

DESIGN OF STUDY

A mixed method study utilising cross-sectional questionnaire survey and semi-structured interviews.

SETTING

A primary care practice in South West England, UK.

METHOD

Responders to the questionnaire survey were drawn from a random sample of individuals, stratified by sex, selected from one practice in the UK (n = 911). The qualitative sample (n = 22) were purposefully selected from the same general practice.

RESULTS

The quantitative data suggest that the majority of people believe individuals utilise either GP or A&E services inappropriately (65.6%; 95% confidence interval [CI] = 62.4 to 68.7). However, strong views relating to this inappropriate healthcare use were not associated with reported seeking of immediate care (odds ratio [OR] = 0.98, 95% CI = 0.66 to 1.46 for 'lump' vignette). Responders tend to consider other people as time wasters, but not themselves. Individuals' generally describe clear rationales for help seeking, even for seemingly trivial symptoms and anxiety level was strongly predictive of health-seeking behaviour (OR = 2.88; 95% CI = 1.98 to 4.19 for lump vignette).

CONCLUSION

Perceptions that individuals' use health services inappropriately are unlikely to explain differences in help-seeking behaviours. The findings suggest that people do not take the decision to consult health services lightly and rationalise why their behaviour is not time wasting.

Patient preferences for treatment for angina: an overview of findings from three studies

BACKGROUND

Access to cardiac treatments has been documented to vary with patients' age. It is unknown whether these variations reflect patients' treatment preferences. We aimed to investigate patients' preferences for cardiology treatments and develop a Patients' Preferences Questionnaire.

METHODS

Semi-structured interviews with primary care patients with diagnosed angina with postal follow-up. The resulting Patients' Preferences Questionnaire was tested with newly admitted inpatients with acute coronary syndrome and with patients in primary care.

RESULTS

The Patients' Preferences Questionnaire was psychometrically sound. Analyses of preference subscale scores showed that the most positive preference scores were for medication. Angioplasty scored highest at the negative end of the scale. Detailed analyses showed that older people and women were less likely to prefer coronary artery bypass surgery (CABG), reflecting its greater level of invasiveness. Older people (aged over 75 years, compared to people aged under 75 years), but not women, were also more cautious in their strength of preference for angioplasty. More positive attitudes towards CABG surgery, and more negative attitudes towards medication, were associated with greater impact of the condition on life.

CONCLUSIONS

The research resulted in a psychometrically sound Patients' Preferences Questionnaire. There was some evidence to support the view that older people's weaker preferences for CABG may contribute slightly to variations in the provision of re-vascularization. There was also variation in preferences within age groups, cautioning against the assumption that all or most older people are more reluctant than younger people to undergo invasive procedures.

Presentation of stable angina pectoris among women and South Asian people

BACKGROUND

There is speculation that women and South Asian people are more likely than men and white people to report atypical angina and that they are less likely to undergo invasive management of angina. We sought to determine whether atypical symptoms of angina pectoris in women and South Asians impacted clinically important outcomes and clinical management.

METHODS

We prospectively identified 2189 South Asian people and 5605 white people with recent-onset chest pain at 6 chest-pain clinics in the United Kingdom. We documented hospital admissions for acute coronary syndromes, coronary deaths as well as coronary angiography and revascularization procedures.

RESULTS

Atypical chest pain was reported by more women than men (56.5% vs 54.5%, p < 0.054) and by more South Asian patients than white patients (59.9% vs 52.5%, p < 0.001). Typical symptoms were associated with coronary death or acute coronary syndromes among women (hazard ratio [HR] 2.30, 95% CI 1.70-3.11, p < 0.001) but not among men (HR 1.23, 95% CI 0.96-1.57, p = 0.10). Typical symptoms were associated with coronary outcomes in both South Asian and white patients. Among those with typical symptoms, women (HR 0.76, 95% CI 0.63-0.92, p = 0.004) and South Asian patients (HR 0.52, 95% CI 0.41-0.67, p < 0.001) were less likely than men and white patients to receive angiography.

INTERPRETATION

Compared to those with atypical chest pain, women and South Asian patients with typical pain had worse clinical outcomes. However, sex and ethnic background did not explain differences in the use of invasive procedures.

What do patients really want? Patients' preferences for treatment for angina

OBJECTIVE

To measure preferences for angina treatments among patients admitted from accident and emergency with acute coronary syndrome.

BACKGROUND

Evidence suggests variability in treatment allocations amongst certain socio-demographic groups (e.g. related to age and sex), although it is unclear whether this reflects patient choice, as research on patients' treatment preferences is sparse. Given current policy emphasis on 'patient choice', providers need to anticipate patients' preferences to plan appropriate and acceptable health services.

DESIGN

Self-administered questionnaire survey.

SETTING

In-patients in a UK hospital.

PARTICIPANTS

A convenience sample of 53 newly admitted patients with acute coronary syndrome. Exclusion criteria were: a previous cardiologist consultation (including previous revascularization); a clinical judgement of too ill to participate; post-admission death; non-cardiac reasons for chest pain.

MAIN OUTCOME MEASURES

Patients' preferences for coronary artery bypass graft (CABG); angioplasty; and two medication alternatives.

RESULTS

Angioplasty was the preferred treatment (for 80% of respondents), and CABG was second (most preferred by 19%, but second most preferred for 60%). The two least preferred (and least acceptable) treatments were medications. The majority of patients (83%) would 'choose treatment based on the extent of benefits' and 'accept any treatment, no matter how extreme, to return to health'. There were some differences in preference related to age (>70 years preferred medication to a greater degree than <70 years) and sex (males preferred CABG surgery more than females).

CONCLUSIONS

There was general preference for procedural interventions over medication, but most patients would accept any treatment, however extreme, to return to former health. There was some evidence of differences in preferences related to age and sex. Furthermore, most patients preferred to have some input into treatment choice (e.g. nearly half wanted to share decision responsibility with their doctor), with only 4% preferring to leave the decision entirely to their doctor. Given these findings, and past findings that suggest there may be variability in treatment allocation according to certain socio-demographic factors, this study suggests a need to develop and use preference measures, and makes a step towards this.

The risk of prostate cancer amongst South Asian men in southern England: the PROCESS cohort study

OBJECTIVE

To reinvestigate whether South Asian men in the UK are at lower risk of being diagnosed with prostate cancer in a UK-based retrospective cohort study and to examine possible reasons that may explain this.

PATIENTS AND METHODS

The catchment areas were predefined in four areas of southern England, and age- and race-specific populations for those areas taken from census data. Cases were ascertained through review of multiple hospital sources, while race, other demographic factors, and medical history were determined using questionnaires sent to the men, hospital records review and death certificates. The South Asian group included men of Indian, Bangladeshi and Pakistani origin.

RESULTS

There was modest evidence of lower prostate cancer rates in South Asian men compared with their White neighbours (age-adjusted rate ratio 0.81; 95% confidence interval 0.65-1.00). This difference did not reflect less use of prostate-specific antigen (PSA) testing or differences in clinical features at presentation.

CONCLUSION

This study provides evidence of a lower incidence of prostate cancer amongst South Asian men living in England, in comparison with their White counterparts. If anything, South Asian men presented with clinical features of earlier disease suggesting that the reduced risk is unlikely to be an artefact of poorer access to health care.

Is severity of chest pain a cue for women and men to recognize acute myocardial infarction symptoms as cardiac in origin?

Recognizing symptoms as cardiac in origin is associated with the prompt seeking of medical care in patients with acute myocardial infarction (AMI). Therefore, the authors compared the symptom attribution of men and women experiencing AMI and examined factors associated with cardiac attribution by sex. In a cross-sectional study, a total of 1059 AMI patients were consecutively recruited across 5 countries. A structured interview was performed during hospitalization. Approximately 40% of both men and women interpreted their symptoms as cardiac in origin. In men, a history of coronary heart disease (CHD) and chest pain severity were significantly associated with symptom interpretation as cardiac in origin (odds ratio [OR], 4.0; 95% confidence interval [CI], 2.9-5.6; OR, 2.0; 95% CI, 1.4-2.7, respectively). In women, a history of CHD was also significantly associated with symptom interpretation as cardiac in origin (OR, 4.95; 95% CI, 2.39-10.25), but not severity of chest pain. As opposed to men, severe chest pain may not be a cue for women to interpret their symptom as cardiac in origin. Education and counseling must take sex differences into account to be effective.

Record linked retrospective cohort study of 4.6 million people exploring ethnic variations in disease: myocardial infarction in South Asians

BACKGROUND

Law and policy in several countries require health services to demonstrate that they are promoting racial/ethnic equality. However, suitable and accurate data are usually not available. We demonstrated, using acute myocardial infarction, that linkage techniques can be ethical and potentially useful for this purpose.

METHODS

The linkage was based on probability matching. Encryption of a unique national health identifier (the Community Health Index (CHI)) ensured that information about health status and census-based ethnicity could not be ascribed to an identified individual. We linked information on individual ethnic group from the 2001 Census to Scottish hospital discharge and mortality data.

RESULTS

Overall, 94% of the 4.9 million census records were matched to a CHI record with an estimated false positive rate of less than 0.1 %, with 84.9 - 87.6% of South Asians being successfully linked. Between April 2001 and December 2003 there were 126 first episodes of acute myocardial infarction (AMI) among South Asians and 30,978 among non-South Asians. The incidence rate ratio was 1.45 (95% CI 1.17, 1.78) for South Asian compared to non-South Asian men and 1.80 (95% CI 1.31, 2.48) for South Asian women. After adjustment for age, sex and any previous admission for diabetes the hazard ratio for death following AMI was 0.59 (95% CI 0.43, 0.81), reflecting better survival among South Asians.

CONCLUSION

The technique met ethical, professional and legal concerns about the linkage of census and health data and is transferable internationally wherever the census (or population register) contains ethnic group or race data. The outcome is a retrospective cohort study. Our results point to increased incidence rather than increased case fatality in explaining high CHD mortality rate. The findings open up new methods for researchers and health planners.

Elderly South Asian Canadian immigrant men: confirming and disrupting dominant discourses about masculinity and men's health

The experiences of elderly South Asian (SA) men who have immigrated to Canada provide unique insights to men's health and illness behaviors and beliefs. In this article, we describe the connections between masculinity, culture, and health among a cohort of 14 SA immigrant men. The findings indicated that participants' health behaviors were closely aligned to those of western men. However, a fine-grained analysis revealed how complex cultural connections informed and influenced many men's health behaviors and beliefs. Based on the study findings, recommendations for the future design of healthcare services targeted to SA men are made.

Acute coronary syndromes and their presentation in Asian and Caucasian patients in Britain

OBJECTIVE

To describe and compare demographics and symptom presentation in Asian and Caucasian patients with acute coronary syndromes.

DESIGN

Long-term prospective survey of symptom presentations in two racial groups.

SETTING

A London hospital.

PARTICIPANTS

A consecutive series of patients admitted to hospital with acute coronary syndromes between November 2001 and November 2005.

MAIN OUTCOME MEASURE

Comparison of demographics and location, character, intensity and symptom distribution at presentation between Asian and Caucasian patients.

RESULTS

Asian patients were younger than Caucasian patients (61 v 69 years, p<0.001) and more had diabetes (43% v 17%, p<0.001). Proportionally, more Asian patients had angina (51% v 37%, p<0.001), but more Caucasian patients had myocardial infarction (63% v 49%, p<0.001) and non-ST elevation infarcts (40% v 29%, p<0.001). Men reported smaller areas of discomfort than women. Asian patients more frequently reported discomfort over the rear of their upper bodies compared to Caucasian patients (46% v 25%, p<0.001) and radiation of discomfort to their arms and necks. A higher percentage of Asian than Caucasian patients demonstrated a "classical" location of symptoms (90% v 82%, p<0.001). Patients with diabetes were more likely to feel no discomfort. A higher percentage of Caucasian than Asian patients presented with "silent" events (13% v 6%, p>0.001), with age being a major determinant.

CONCLUSION

Asian patients were younger, more likely to be diabetic and tended to report a higher intensity of pain and over a greater area of their body, and more frequent discomfort over the rear of their upper thorax than Caucasian patients.

Myocardial infarction symptom recognition by the lay public: the role of gender and ethnicity

STUDY OBJECTIVE

To find out if gender and ethnicity are associated with acute myocardial infarction (AMI) symptom recognition and the recommendation of enlisting emergency medical services.

DESIGN

In an experiment, a random sample of the public was provided a scenario of a person experiencing symptoms of AMI; the gender of the character (male, female, or indeterminate) was manipulated.

SETTING

Vancouver, Canada

PARTICIPANTS

976 people from a population based random sample of 3419 people, 40 years of age and older, participated in a telephone survey given in English, Cantonese, Mandarin, and Punjabi.

MAIN RESULTS

78% of the respondents identified the symptoms as heart related. Unadjusted analyses showed that ethnicity, education, income, and AMI knowledge were significantly associated with symptom recognition (Chinese respondents were least likely to identify the symptoms as heart related). Thirty seven per cent recommended calling emergency services, which was associated with symptom recognition, ethnicity (Chinese respondents were least likely to make the recommendation), AMI knowledge, having an immediate family member with AMI, and having talked with a health professional about the signs and symptoms of AMI. Neither the gender of the respondent nor of the affected person in the scenario was associated with symptom recognition.

CONCLUSIONS

Heart health education must be targeted to and tailored for ethnic communities. Health professionals must discuss the signs and symptoms of AMI, and the correct course of action, with their patients.

Knowledge of modifiable risk factors of heart disease among patients with acute myocardial infarction in Karachi, Pakistan: a cross sectional study

Background

Knowledge is an important pre-requisite for implementing both primary as well as secondary preventive strategies for cardiovascular disease (CVD). There are no estimates of the level of knowledge of risk factor of heart disease in patients with CVD. We estimated the level of knowledge of modifiable risk factors and determined the factors associated with good level of knowledge among patients presenting with their first acute myocardial infarction (AMI) in a tertiary care hospital in Karachi, Pakistan.

Methods

A hospital based cross-sectional study was conducted at the National Institute of Cardiovascular Disease, a major tertiary care hospital in Karachi Pakistan. Patients admitted with their first AMI were eligible to participate. Standard questionnaire was used to interview 720 subjects. Knowledge of four modifiable risk factors of heart disease: fatty food consumption, smoking, obesity and exercise were assessed. The participants knowing three out of four risk factors were regarded as having a good level of knowledge. A multiple logistic regression model was constructed to identify the determinants of good level of knowledge.

Results

The mean age (SD) was 54 (11.66) years. A mere 42% of our study population had a good level of knowledge. In multiple logistic regression analysis, independent predictors of "good" level of knowledge were (odds ratio [95% confidence interval]) more than ten years of schooling were 2.5 [1.30, 4.80] (verses no schooling at all) and nuclear family system (verses extended family system) 2.54 [1.65, 3.89]. In addition, Sindhi ethnicity OR [3.03], higher level of exercise OR [2.76] and non user of tobacco OR [2.53] were also predictors of good level of knowledge.

Conclusion

Our findings highlight the lack of good level of knowledge of modifiable risk factors for heart disease among subjects admitted with AMI in Pakistan. There is urgent need for aggressive and targeted educational strategies in the Pakistani population.

Factors influencing Hong Kong Chinese patients' decision-making in seeking early treatment for acute myocardial infarction

The purpose of this study was to identify, through in-depth interview, factors that influenced 27 Hong Kong Chinese patients' decision-making in seeking early treatment for acute myocardial infarction (AMI). The median delay time from the onset of symptoms to arrival at the hospital was 15.6 hours for men and 53.7 hours for women. Three major categories emerged from the data: (a) becoming aware of the threat, (b) maintaining a sense of normality, and (c) struggling to mobilize resources. A variety of decisions were made by patients from the onset of chest pain to seeking help. These decisions were heavily influenced by healthcare factors (access to emergency medical service (EMS) and treatment), personal factors (cognitive interpretations of symptoms), sociocultural factors (family situation, cultural beliefs, and practices), and coping strategies.

Ethnicity and variation in prognosis for patients newly hospitalised for heart failure: a matched historical cohort study

OBJECTIVES

To compare mortality and factors predictive for outcome in age matched white and South Asian cohorts after first admission for heart failure.

DESIGN

Matched historical cohort study.

SETTING

One National Health Service trust comprising three acute care hospitals.

PARTICIPANTS

176 South Asian (mean age 68 (10) years, 45% women) and 352 age and sex matched white (70 (11) years, 42% women) patients hospitalised for the first time with heart failure.

MAIN OUTCOME MEASURES

All cause survival, measures of disease severity, and the association of clinical variables with outcome.

RESULTS

Compared with white patients, South Asian patients had similar rates of prior coronary heart disease but more often had prior hypertension (45% v 33%, p = 0.006) and diabetes (46% v 18%, p < 0.0001). Atrial fibrillation (15% v 31%, p = 0.0002) and prior diuretic use (39% v 48%, p = 0.041) were less common among South Asians. Left ventricular function was more often preserved (38% v 23%, p = 0.002) and less often severely impaired (18% v 28%, p = 0.025) among South Asians. During follow up (range 520-1880 days) 73 of 176 (41.2%) South Asian and 167 of 352 (47.4%) white patients died. South Asian ethnicity was associated with lower all cause mortality (odds ratio 0.71, 95% confidence interval 0.53 to 0.96, p = 0.02). Other predictors of outcome (admission age, lower systolic blood pressure, higher creatinine, higher plasma glucose, and lower haemoglobin) were similar in each cohort.

CONCLUSIONS

At first hospitalisation, heart failure appears less advanced in South Asians, among whom diabetes and hypertension are more prevalent. Survival is better for South Asian than for white patients. Higher glucose and lower haemoglobin at admission provide useful prognostic information in heart failure.

Gender and age inequity in the provision of coronary revascularisation in England in the 1990s: is it getting better?

Although the mortality and incidence of coronary heart disease (CHD) in England and Wales has declined in recent years, an ageing population has contributed to keeping the prevalence of CHD largely unchanged. Evidence suggests that revascularisation procedures have contributed not only to this decline in mortality, but also to the decline in morbidity from heart disease, and to improvements in quality of life, even in old age. Despite clinical evidence of benefit, revascularisation is less often provided for older people and for women. This paper considers the equity of the provision of revascularisation according to need by gender and age using the Hospital Episodes Statistics (HES) database which includes all NHS hospital admissions in England. Trends from 1991 to 1999 were examined comparing admissions for acute myocardial infarction (as a proxy indicator of need in the absence of direct measures) and the procedures coronary artery bypass grafting (CABG) and percutaneous transluminal coronary angioplasty (PTCA). The rates of CABG and PTCA have increased dramatically by 72% and 48%, respectively, between 1991/3 and 1997/9. Making allowance for differences in need, to achieve equitable provision with men, over 12,000 extra CABG and over 5000 PTCA procedures would be required for women, amounting to 19% and 10% increases in the total volume of each procedure, respectively. Similarly, attempting to meet need up to the age of 79 years would require over 13,000 extra CABG and over 13,000 PTCA procedures for men, and an additional 14,300 CABG and almost 10,000 extra PTCA procedures for women, representing 42% and 40% increases in CABG and PTCA, respectively. As women tend to present with CHD at older ages this indicates that they may be the victims of a 'double whammy' of inequity. Moreover, these inequities have remained constant through the study period. Possible explanations for this shortfall of provision are proposed.

Does access to cardiac investigation and treatment contribute to social and ethnic differences in coronary heart disease? Whitehall II prospective cohort study

OBJECTIVE

To determine whether access to cardiac procedures and drugs contributes to social and ethnic differences in coronary heart disease in a population setting.

DESIGN

Prospective study with follow up over 15 years. Civil service employment grade was used as a measure of individual socioeconomic position. Need for cardiac care was determined by the presence of angina, myocardial infarction, and coronary risk factors.

SETTING

20 civil service departments originally located in London.

PARTICIPANTS

10,308 civil servants (3414 women; 560 South Asian) aged 35-55 years at baseline in 1985-8.

MAIN OUTCOME MEASURES

Use of exercise electrocardiography, coronary angiography, and coronary revascularisation procedures and secondary prevention drugs.

RESULTS

Inverse social gradients existed in incident coronary morbidity and mortality. South Asian participants also had higher rates than white participants. After adjustment for clinical need, social position showed no association with the use of cardiac procedures or secondary prevention drugs. For example, men in the low versus high employment grade had an age adjusted odds ratio for angiography of 1.87 (95% confidence interval 1.32 to 2.64), which decreased to 1.27 (0.83 to 1.94) on adjustment for clinical need. South Asians tended to be more likely to have cardiac procedures and to be taking more secondary prevention drugs than white participants, even after adjustment for clinical need.

CONCLUSION

This population based study, which shows the widely observed social and ethnic patterning of coronary heart disease, found no evidence that low social position or South Asian ethnicity was associated with lower use of cardiac procedures or drugs, independently of clinical need. Differences in medical care are unlikely to contribute to social or ethnic differences in coronary heart disease in this cohort.

Noncardiac chest pain: epidemiology, natural history, health care seeking, and quality of life

The epidemiology of NCCP is poorly described, and the available data are conflicting. Population-based studies on the prevalence of NCCP are rare; most studies have been hospital based. According to the limited studies available, the annual prevalence of NCCP is approximately 25%. Despite this significant burden, the impact and natural history of NCCP in the community has not been adequately explored. NCCP is presumed to bea heterogeneous condition. Hospital-based studies have suggested that GERD, esophageal spasm, psychiatric disease (including panic attacks), and musculoskeletal pain explain many cases of NCCP. However, unrecognized coronary artery disease and microvascular angina (cardiac syndrome X)also explain an unknown proportion of cases in the general population.Current studies suggest that NCCP is common in the general population and significantly affects QOL, yet only a minority seeks medical attention.The epidemiology of NCCP requires further study in the general population and in those attending the Emergency Department.

Ethnicity, socio-economic position and gender--do they affect reported health-care seeking behaviour?

While the pursuit of equity of access to health care is a central objective of many health care systems, there is evidence that patients of ethnic minority descent, in lower socio-economic position (SEP) or of female gender are less likely than Whites, more affluent groups or men, respectively, to access secondary and tertiary medical care. However, it is unclear at which point in the chain of events leading from perception of need through attendance at primary/emergency care, to referral and receipt of secondary care, this inequality occurs. This study examined the influence of ethnicity, socio-economic position and gender on an individual's perception of the need and urgency for seeking health care. A random sample was selected from two large city General Practices in the UK who were sent postal questionnaires which included two clinical vignettes describing characters experiencing chest pain and discovering a lump in the armpit. The main outcome measure was response to the 'chest pain' and 'lump' vignettes in terms of immediate health care utilisation. The questionnaire survey (n=1350, response rate 66%) indicated that Black respondents, respondents from lower socio-economic groups and women were at least as likely to report immediate health care seeking in response to the clinical vignettes than White respondents, those from higher socio-economic groups or men. This finding was consistent across all scenarios after adjustment for interpretation of the vignette, access to health services and attitudes to health and health care. For example, those in the lowest SEP group were almost 60% more likely to report immediate care seeking in response to the lump vignette (OR 1.59, 95% CI 1.08-2.33) compared to those in the highest SEP group; and Black respondents 40% more likely (OR 1.41, 95% CI 0.92-2.17). This study suggests inequalities in access to health care by ethnicity, socio-economic position and gender are not related to patients in these groups failing to self-refer to primary or accident and emergency care, barriers must therefore occur at the level of health care provision.

How did the recent increase in the supply of coronary operations in Finland affect socioeconomic and gender equity in their use?

STUDY OBJECTIVE

To explore how the increased supply of coronary bypass operations and angioplasties from 1988 to 1996 influenced socioeconomic and gender equity in their use.

DESIGN

Register based linkage study; information on coronary procedures from the Finnish Hospital Discharge Register in 1988 and 1996 was individually linked to national population censuses in 1970-1995 to obtain patients' socioeconomic data. Data on both hospitalisations and mortality attributable to coronary heart disease obtained from similar linkage schemes were used to approximate the relative need of procedures in socioeconomic groups.

SETTING

Finland, 2,094,846 inhabitants in 1988 and 2,401,027 in 1996 aged 40 years and older, and Discharge Register data from all Finnish hospitals offering coronary procedures in 1988 and 1996.

MAIN RESULTS

The overall rate of coronary revascularisations in Finland increased by about 140% for men and 250% for women from 1988 to 1996. Over the same period, socioeconomic and gender disparities in operation rates diminished, as did the influence of regional supply of procedures on the extent of these differences. However, men, and better off groups in terms of occupation, education, and family income, continued to receive more operations than women and the worse off with the same level of need.

CONCLUSIONS

Although revascularisations in Finland increased 2.5-fold overall, some socioeconomic and gender inequities persisted in the use of cardiac operations relative to need. To improve equity, a further increase of resources may be needed, and practices taking socioeconomic and gender equity into account should be developed for the referral of coronary heart disease patients to hospital investigations.
