Gender Bias in Cardiovascular Testing Persists after Adjustment for Presenting Characteristics and Cardiac Risk

Sex/gender bias in the management of chest pain in ambulatory care

Objective:

Cardiovascular diseases (CVD) are the main cause of death worldwide and despite a higher prevalence in men, mortality from CVD is higher among women. Few studies have assessed sex differences in chest pain management in ambulatory care. The objective of this post hoc analysis of data from a prospective cohort study was to assess sex differences in the management of chest pain in ambulatory care.

Setting:

We used data from the Thoracic Pain in Community cohort study that was realized in 58 primary care practices and one university ambulatory clinic in Switzerland.

Participants:

In total, 672 consecutive patients aged over 16 years attending a primary care practice or ambulatory care clinic with a complaint of chest pain were included between February and June 2001. Their mean age was 55.2 years and 52.5% were women.

Main outcome measures:

The main outcome was the proportion of patients referred to a cardiologist at 12 months follow-up. A panel of primary care physicians assessed the final diagnosis retained for chest pain at 12 months.

Results:

The prevalence of chest pain of cardiovascular origin (n = 108, 16.1%) was similar for men and women (17.5% vs 14.8%, respectively, p = 0.4). Men with chest pain were 2.5 times more likely to be referred to a cardiologist than women (16.6% vs 7.4%, odds ratio: 2.49, 95% confidence interval: 1.52–4.09). After adjustment for the patients’ age and cardiovascular disease risk factors, the estimates did not significantly change (odds ratio: 2.30, 95% confidence interval: 1.30–3.78).

Conclusion:

Although the same proportion of women and men present with a chest pain of cardiovascular origin in ambulatory care, there is a strong sex bias in their management. These data suggest that effort must be made to assure equity between men and women in medical care.

Paediatric-onset coronary artery anomalies in pregnancy: a single-centre experience and systematic literature review

OBJECTIVES

Individuals with childhood-onset coronary artery anomalies are at increased risk of lifelong complications. Although pregnancy is thought to confer additional risk, a few data are available regarding outcomes in this group of women. We sought to define outcomes of pregnancy in this unique population.

METHODS

We performed a retrospective survey of women with paediatric-onset coronary anomalies and pregnancy in our institution, combined with a systematic review of published cases. We defined paediatric-onset coronary artery anomalies as congenital coronary anomalies and inflammatory arteriopathies of childhood that cause coronary aneurysms. Major cardiovascular events were defined as pulmonary oedema, sustained arrhythmia requiring treatment, stroke, myocardial infarction, cardiac arrest, or death.

RESULTS

A total of 25 surveys were mailed, and 20 were returned (80% response rate). We included 46 articles from the literature, which described cardiovascular outcomes in 82 women (138 pregnancies). These data were amalgamated for a total of 102 women and 194 pregnancies; 59% of women were known to have paediatric-onset coronary artery anomalies before pregnancy. In 23%, the anomaly was unmasked during or shortly after pregnancy. The remainder, 18%, was diagnosed later in life. Major cardiovascular events occurred in 14 women (14%) and included heart failure (n=5, 5%), myocardial infarction (n=7, 7%), maternal death (n=2, 2%), cardiac arrest secondary to ventricular fibrillation (n=1, 1%), and stroke (n=1, 1%). The majority of maternal events (13/14, 93%) occurred in women with no previous diagnosis of coronary disease.

CONCLUSIONS

Women with paediatric-onset coronary artery anomalies have a 14% risk of adverse cardiovascular events in pregnancy, indicating the need for careful assessment and close follow-up. Prospective, multicentre studies are required to better define risk and predictors of complications during pregnancy.

Disparities by Sex Tracked in the 2015 National Healthcare Quality and Disparities Report: Trends across National Quality Strategy Priorities, Health Conditions, and Access Measures

INTRODUCTION

Established by the Affordable Care Act, the National Quality Strategy (NQS) is the national policy goals aimed at improving the quality of health care for all Americans. The NQS established six priorities to provide better, more affordable care for individuals and communities. This is the first analysis of data on the NQS and access measures that focus on sex differences, health conditions, trends, and disparities.

METHODS

Measures from the 2015 National Healthcare Quality and Disparities Report (QDR) for the four National Quality Strategy priorities (Patient Safety, Person Centered Care, Effective Treatment, and Healthy Living), access to care, and health conditions for women were compared to measures for men. Trends were analyzed for women by health condition and the four NQS priorities and access to care. Baseline year (2000-2002) and most current year (2012-2013) were compared to assess disparity trends. All non-institutionalized women and men in the U.S. over the age of 18 were included in the sample.

RESULTS

Disparities between males and females for the four NQS priority and access measures did not change for 83 percent of measures (n=81); disparities remained constant. The greatest improvement over time for females from the baseline year was in the patient safety measures (3.66 percent increase per year). Access of care measures showed the least amount of improvement with a median change of -1.20 percent per year. The greatest improvement in quality of care by health condition was amongst chronic kidney disease (11.95 median percent change) and HIV/AIDS (6.63 median percent change) measures. Behavioral health measures showed the least amount of improvement with a median change of -0.33 percent per year.

CONCLUSIONS

This analysis highlights cardiovascular disease, behavioral health, and access to care as problem areas for women that require immediate attention. It is of concern that 83% of the measures showed a persistent disparity over time between men and women. These results indicate that there is room for improving the quality of healthcare received by women and reducing sex-based disparities experienced by women in the healthcare delivery system.

Gender Differences in CDC Guideline Compliance for STIs in Emergency Departments

Introduction

Sexually transmitted infections (STIs) are a common reason for emergency department (ED) visits. The objective of this study was to determine if there were gender differences in adherence to Centers for Disease Control and Prevention (CDC) STI diagnosis and treatment guidelines, as documented by emergency providers.

Methods

We performed a retrospective chart review to identify patients treated for urethritis, cervicitis, and pelvic inflammatory disease (PID) in the EDs of three hospitals in a Pennsylvania network during a calendar year. Cases were reviewed to assess for compliance with CDC guidelines. We used descriptive statistics to assess the distributions of study variables by patient sex. In the analysis we used Student’s t-tests, chi-square tests, and logistic regression. Statistical significance was set at p ≤ 0.05.

Results

We identified 286 patient records. Of these, we excluded 39 for the following reasons: incorrect disease coding; the patient was admitted and treated as an inpatient for his/her disease; or the patient left the ED after refusing care. Of the 247 participants, 159 (64.4%) were female. Females were significantly younger (26.6 years, SD=8.0) than males (31.2, SD=11.5%), (95% confidence interval [CI] [2.0– 7.0], p=0.0003). All of the males (n=88) in the cohort presented with urethritis; 25.8% of females presented with cervicitis, and 74.2% with PID. Physician compliance for the five CDC criteria ranged from 68.8% for patient history to 93.5% for patient diagnostic testing, including urine pregnancy and gonorrhea/chlamydia cultures. We observed significant differences by patient sex. Fifty-four percent of the charts had symptoms recorded for female patients that were consistent with CDC characteristics for diagnostic criteria compared to over 95% for males, OR=16.9; 95% CI [5.9–48.4], p<0.001. Similar results were observed for patient discharge instructions, with physicians completely documenting delivery of discharge instructions to 51.6% of females compared to 97.7% of complete documentation in males, OR=42.3; 95% CI [10.0–178.6] p<0.001). We observed no significant sex differences in physician documentation for physical exam or for therapeutic antibiotic treatment.

Conclusion

This retrospective study found patient gender differences in how emergency providers complied with documenting with regard to the 2010 CDC guidelines for the diagnosis and treatment of urethritis, cervicitis, and PID. Specifically medical records of men were more likely to have complete documentation of symptoms recorded (95% CI 5.9–48.4) and to have discharge instruction documentation (95% CI 10.0–178.6) than records of women.

Advancing Women's Health and Women's Leadership With Endowed Chairs in Women's Health

Gender-based bias and conflation of gender and status are root causes of disparities in women's health care and the slow advancement of women to leadership in academic medicine. More than a quarter of women physicians train in internal medicine and its subspecialties, and women physicians almost exclusively constitute the women's health focus within internal medicine. Thus, internal medicine has considerable opportunity to develop women leaders in academic medicine and promote women's health equity.To probe whether holding an endowed chair-which confers status-in women's health may be an effective way to advance women leaders in academic medicine and women's health, the authors explored the current status of endowed chairs in women's health in internal medicine. They found that the number of these endowed chairs in North America increased from 7 in 2013 to 19 in 2015, and all were held by women. The perceptions of incumbents and other women's health leaders supported the premise that an endowed chair in women's health would increase women's leadership, the institutional stature of women's health, and activities in women's health research, education, and clinical care.Going forward, it will be important to explore why not all recipients perceived that the endowed chair enhanced their own academic leadership, whether providing women's health leaders with fundraising expertise fosters future success in increasing the number of women's health endowed chairs, and how the conflation of gender and status play out (e.g., salary differences between endowed chairs) as the number of endowed chairs in women's health increases.

Do Gender and Race Make a Difference in Acute Coronary Syndrome Pretest Probabilities in the Emergency Department?

OBJECTIVES

The objective was to test for significant differences in subjective and objective pretest probabilities for acute coronary syndrome (ACS) in a large cohort of chest pain patients stratified by race or gender. Secondarily we wanted to test for any differences in rates of ACS, rates of 90-day returns, cost, and chest radiation exposure after these stratifications.

METHODS

This is a secondary analysis of a prospective outcomes study of ED patients with chest pain and shortness of breath. We performed two separate analyses. The data set was divided by gender for analysis 1 while the analysis 2 stratification was made by race (nonwhite vs. white). For each analysis, groups were compared on several variables: provider visual analog scales (VAS) for likelihood of ACS, PREtest Consult ACS probabilities, rates of ACS, total radiation exposure to the chest, total costs at 30 days, and 90-day recidivism (ED, overnight observations, and inpatient admissions).

RESULTS

A total of 844 patients were studied. Gender information was present on all 844 subjects, while complete race/ethnicity information was available on 783 (93%) subjects. For the first analysis, female patients made up 57% (478/844) of the population and their mean provider VAS scores for ACS were significantly lower (p = 0.000) at 14% (95% confidence interval [CI] = 13% to 16%) than that of males at 22% (95% CI = 19% to 24%). This was consistent with the objective pretest ACS probabilities subsequently calculated via the validated online tool, PREtest Consult, which were also significantly lower (p = 0.000) at 2.7% (95% CI = 2.4% to 3.1%) for females versus 6.6% (95% CI = 5.9% to 7.3%) for males. However, comparing females to males, there was no significant difference in diagnosis of ACS (3.6% vs. 1.6%), mean chest radiation doses (5.0 mSv vs. 4.9 mSv), total costs at 30 days ($3,451.24 vs. $3,847.68), or return to the ED within 90 days (26% each). For analysis 2 by race, nonwhite patients also comprised 57% (444/783) of individuals. Similar to the gender analysis, mean provider VAS scores for ACS were found to be significantly lower (p = 0.000) at 15% (95% CI = 13% to 16%) for nonwhite versus 20% (95% CI = 18% to 23%) for white subjects. Concordantly, objective pretest ACS probabilities were also significantly lower (p = 0.000) at 3.4% (95% CI = 2.9% to 3.9%) for nonwhite versus 5.3% (95% CI = 4.7% to 5.9%) for white subjects. There were no significant differences in outcomes in nonwhite versus white subjects when compared on diagnosis of ACS (3.2% vs 2.4%), mean chest radiation dose (4.6 mSv vs. 5.0 mSv), cost ($3,156.02 vs. $2,885.18), or 90-day ED returns (28% vs. 23%).

CONCLUSIONS

Despite consistently estimating the risk for ACS to be lower for both females and minorities concordantly with calculated objective pretest assessments, there does not appear to have been any significant decrease in subsequent evaluation of these perceived lower-risk groups when radiation exposure and costs are taken into account. Further studies on the impact of pretest assessments on gender and racial disparities in ED chest pain evaluation are needed.

Developing a Tool for Increasing the Awareness about Gendered and Intersectional Processes in the Clinical Assessment of Patients--A Study of Pain Rehabilitation

OBJECTIVE

There is a need for tools addressing gender inequality in the everyday clinical work in health care. The aim of our paper was to develop a tool for increasing the awareness of gendered and intersectional processes in clinical assessment of patients, based on a study of pain rehabilitation.

METHODS

In the overarching project named "Equal care in rehabilitation" we used multiple methods (both quantitative and qualitative) in five sub studies. With a novel approach we used Grounded Theory in order to synthesize the results from our sub studies, in order to develop the gender equality tool. The gender equality tool described and developed in this article is thus based on results from sub studies about the processes of assessment and selection of patients in pain rehabilitation. Inspired by some questions in earlier tools, we posed open ended questions and inductively searched for findings and concepts relating to gendered and social selection processes in pain rehabilitation, in each of our sub studies. Through this process, the actual gender equality tool was developed as 15 questions about the process of assessing and selecting patients to pain rehabilitation. As a more comprehensive way of understanding the tool, we performed a final step of the GT analyses. Here we synthesized the results of the tool into a comprehensive model with two dimensions in relation to several possible discrimination axes.

RESULTS

The process of assessing and selecting patients was visualized as a funnel, a top down process governed by gendered attitudes, rules and structures. We found that the clinicians judged inner and outer characteristics and status of patients in a gendered and intersectional way in the process of clinical decision-making which thus can be regarded as (potentially) biased with regard to gender, socio-economic status, ethnicity and age.

IMPLICATIONS

The clinical implications of our tool are that the tool can be included in the systematic routine of clinical assessment of patients for both awareness raising and as a base for avoiding gender bias in clinical decision-making. The tool could also be used in team education for health professionals as an instrument for critical reflection on gender bias.

CONCLUSIONS

Thus, tools for clinical assessment can be developed from empirical studies in various clinical settings. However, such a micro-level approach must be understood from a broader societal perspective including gender relations on both the macro- and the meso-level.

Gender Inequalities in Access to Health Care among Adults Living in British Columbia, Canada

INTRODUCTION

Existing literature is inconclusive as to whether disparities in access to health care between men and women are mainly driven by socioeconomic or gender inequalities. The aim of this study was to assess whether gender was independently associated with perceived unmet health care needs among a representative sample of British Columbia adults.

METHODS

Using data from the 2011/2012 Canadian Community Health Survey, logistic regression analyses were conducted to investigate the independent effect of gender on perceived unmet health care needs adjusting for potential individual and contextual confounders.

RESULTS

Among 12,252 British Columbia adults (51.9% female), the prevalence of perceived unmet health care needs was 12.0%, with a significantly greater percentage among women compared with men (13.7% vs. 10.1%; p < .001). After adjusting for multiple confounders, women had independently increased odds of perceived unmet health care needs (adjusted odds ratio, 1.37; 95% CI, 1.11-1.68).

DISCUSSION

The current study found that, among a representative sample of British Columbia adults and adjusting for various individual and contextual factors, female gender was associated independently with an increased odds of perceived unmet health care needs.

CONCLUSION

These findings suggest that within Canada's universal health system, gender further explains differences in health care access, over and above socioeconomic inequalities. Interventions within and outside the health sector are required to achieve equitable access to health care for all residents in British Columbia.

Gender-specific research for emergency diagnosis and management of ischemic heart disease: proceedings from the 2014 Academic Emergency Medicine Consensus Conference Cardiovascular Research Workgroup

Coronary artery disease (CAD) is the most common cause of death for both men and women. However, over the years, emergency physicians, cardiologists, and other health care practitioners have observed varying outcomes in men and women with symptomatic CAD. Women in general are 10 to 15 years older than men when they develop CAD, but suffer worse postinfarction outcomes compared to age-matched men. This article was developed by the cardiovascular workgroup at the 2014 Academic Emergency Medicine (AEM) consensus conference to identify sex- and gender-specific gaps in the key themes and research questions related to emergency cardiac ischemia care. The workgroup had diverse stakeholder representation from emergency medicine, cardiology, critical care, nursing, emergency medical services, patients, and major policy-makers in government, academia, and patient care. We implemented the nominal group technique to identify and prioritize themes and research questions using electronic mail, monthly conference calls, in-person meetings, and Web-based surveys between June 2013 and May 2014. Through three rounds of nomination and refinement, followed by an in-person meeting on May 13, 2014, we achieved consensus on five priority themes and 30 research questions. The overarching themes were as follows: 1) the full spectrum of sex-specific risk as well as presentation of cardiac ischemia may not be captured by our standard definition of CAD and needs to incorporate other forms of ischemic heart disease (IHD); 2) diagnosis is further challenged by sex/gender differences in presentation and variable sensitivity of cardiac biomarkers, imaging, and risk scores; 3) sex-specific pathophysiology of cardiac ischemia extends beyond conventional obstructive CAD to include other causes such as microvascular dysfunction, takotsubo, and coronary artery dissection, better recognized as IHD; 4) treatment and prognosis are influenced by sex-specific variations in biology, as well as patient-provider communication; and 5) the changing definitions of pathophysiology call for looking beyond conventionally defined cardiovascular outcomes to patient-centered outcomes. These emergency care priorities should guide future clinical and basic science research and extramural funding in an area that greatly influences patient outcomes.

Does pain severity guide selection to multimodal pain rehabilitation across gender?

BACKGROUND

Studies have addressed the effect of multimodal pain rehabilitation (MMR), whereas criteria for selection are sparse. This study examines whether higher scores on musculoskeletal pain measures are associated with selection to MMR, and whether this differs across gender.

METHOD

A clinical population of 262 male and 589 female patients was recruited consecutively during 3 years, 2007-2010. The patients were referred from primary care to a pain rehabilitation clinic in Northern Sweden for assessment and selection to MMR. Register-based data on self-reported pain were linked to patients' records where outcome (MMR or not) was stated. We modelled odds ratios for selection to MMR by higher scores on validated pain measures (pain severity, interference with daily life, pain sites and localized pain vs. varying pain location). Covariates were age, educational level and multiple pain measures. Anxiety and depression (Hospital, Anxiety and Depression Scale) and working status were used in sensitivity tests.

RESULTS

Higher scores of self-reported pain were not associated with selection to MMR in multivariate models. Among women, higher scores on pain severity, pain sites and varying pain location (localized pain = reference) were negatively associated with selection to MMR. After adjustment for multiple pain measures, the negative odds ratio for varying location persisted (OR = 0.59, 95% CI = 0.39-0.89).

CONCLUSION

Higher scores on self-reported pain did not guide selection to MMR and a negative trend was found among women. Studies of referral patterns and decision processes may contribute to a better understanding of the clinical practice that decides selection to MMR.

Quantifying the defensive medicine contribution to primary care costs

BACKGROUND

Defensive medicine represents one cause of economic losses in healthcare. Studies that measured its cost have produced conflicting results.

OBJECTIVE

To directly measure the proportion of primary care costs attributable to defensive medicine.

RESEARCH DESIGN AND METHODS

Six-week prospective study of primary care physicians from four outpatient practices. On 3 distinct days, participants were asked to rate each order placed the day before on the extent to which it represented defensive medicine, using a 5-point scale from 0 (not at all defensive) to 4 (entirely defensive).

MAIN OUTCOME MEASURES

This study calculated the order defensiveness score for each order (the defensiveness/4) and the physician defensive score (the mean of all orders defensiveness scores). Each order was assigned a weighted cost by multiplying the total cost of that order (based on Medicare reimbursement rates) by the order defensiveness score. The proportion of total cost attributable to defensive medicine was calculated by dividing the weighted cost of defensive orders by the total cost of all orders.

RESULTS

Of 50 eligible physicians, 23 agreed to participate; 21 returned the surveys and rated 1234 individual orders on 347 patients. Physicians wrote an average of 3.6 ± 1.0 orders/visit with an associated total cost of $72.60 ± 18.5 per order. Across physicians, the median physician defensive score was 0.018 (IQR = [0.008, 0.049]) and the proportion of costs attributable to defensive medicine was 3.1% (IQR = [0.5%, 7.2%]). Physicians with defensive scores above vs below the median had a similar number of orders and total costs per visit. Physicians were more likely to place defensive orders if trained in community hospitals vs academic centers (OR = 4.29; 95% CI = 1.55-11.86; p = 0.01).

CONCLUSIONS

This study describes a new method to directly quantify the cost of defensive medicine. Defensive medicine appears to have minimal impact on primary care costs.

Women and NCDs: overcoming the neglect

Two in every three deaths among women are caused by non-communicable diseases (NCDs) – largely heart disease, stroke, cancer, diabetes and chronic respiratory diseases. The global discourse on health, however, largely views women in terms of their reproductive capacity, a persisting myth reflecting gender bias that shifts the focus away from NCDs, violence, and other injuries. Risk factors for NCDs are similar for men and women. Because fewer women actively smoke than men, and drink in less harmful ways, in most parts of the world, the impact of major NCD risk factors is far less in women than in men. In the area of diagnosis and treatment, gender bias can result in women being asked fewer questions, and receiving fewer examinations and fewer diagnostic tests for coronary heart disease and other NCDs compared with men with similar symptoms. In response to a UN meeting in September 2011, member states of WHO have agreed to a global goal to reduce avoidable NCD mortality by 25% by 2025 (‘25 by 25’). A set of voluntary targets and indictors have been agreed upon, although none of them are gender specific. Most require changes at the policy level that will ensure that women – and children – will also benefit. As the 2015 deadline for the Millennium Development Goals approaches, women and NCDs should be central to the sustainable human development agenda.

Salhi R, Hollander JE. Relationship between body mass index and prognosis of patients presenting with potential acute coronary syndromes

OBJECTIVES

Studies examining the relationship between obesity and acute coronary syndrome (ACS) have been limited to patients with confirmed diagnoses. The authors sought to determine the relationship between body mass index (BMI) and 30-day cardiovascular events in emergency department (ED) patients with potential ACS.

METHODS

This was a secondary analysis of a prospective cohort study of patients who presented to the ED with potential ACS. Patients were stratified according to their BMI: underweight (BMI < 18.49 kg/m(2) ), normal weight (BMI = 18.5 to 24.99 kg/m(2) ), overweight (BMI = 25 to 29.99 kg/m(2) ), obese (BMI = 30 to 34.99 kg/m(2) ), and very obese (BMI > 35 kg/m(2) ). The primary outcome was acute myocardial infarction (AMI), death, or revascularization within 30 days of presentation. A logistic regression analysis was used to adjust for confounding variables and adjusted odds ratios (aOR) with 95% confidence intervals (CIs) are presented for cardiac events and readmission outcomes.

RESULTS

Of the 3,946 patients included in this study, 73 (1.9%) were underweight, 911 (23%) were normal weight, 1,199 (30.4%) were overweight, 872 (22.1%) were obese, and 891 (22.6%) were very obese. Although increased levels of obesity were associated with a greater number of cardiac risk factors, there was no difference in 30-day cardiovascular events between those of normal weight and underweight (aOR = 1.1; 95% CI = 0.4 to 2.7), overweight (aOR = 1.0; 95% CI = 0.7 to 1.4), obese (aOR = 1.2; 95% CI = 0.8 to1.7), or very obese (aOR = 0.8; 95% CI = 0.5 to 1.3). Those who were underweight were more likely to be readmitted within 30 days (aOR = 1.9; 95% CI = 1.0 to 3.7), and those who were very obese were less likely to be readmitted within 30 days (aOR = 0.7; 95% CI = 0.5 to 0.9).

CONCLUSIONS

Among patients who present to the ED with potential ACS, BMI is not associated with higher risk of cardiovascular outcomes at 30 days.

Using patients' narratives to reveal gender stereotypes among medical students

PURPOSE

Gender bias exists in patient treatment, and, like most people, health care providers harbor gender stereotypes. In this study, the authors examined the gender stereotypes that medical students hold about patients.

METHOD

In 2005, in Umeå, Sweden, the authors collected 81 narratives written by patients who had undergone cancer treatment; all information that might reveal the patients' gender was removed from the texts. Eighty-seven medical students read 40 or 41 narratives each, guessed the patient's gender, and explained their guess. The authors analyzed the students' explanations qualitatively and quantitatively to reveal the students' gender stereotypes and to determine whether those stereotypes had any predictive value for correctly guessing a patient's gender.

RESULTS

The students' explanations contained 21 categories of justifications, 12 of which were significantly associated with the students guessing one gender or the other. Only three categories successfully predicted a correct identification of gender; two categories were more often associated with incorrect guesses.

CONCLUSIONS

Medical students enter their training program with culturally shared stereotypes about male and female patients that could cause bias during their future careers as physicians. To prevent this, medical curricula must address gender stereotypes and their possible consequences. The impact of implicit stereotypes must be included in discussions about gender bias in health care.

Sex preferences in cardiovascular testing: the contribution of the patient-physician discussion

OBJECTIVES

Prior studies suggest that a decreased cardiac catheterization rate for women with acute coronary syndrome (ACS) is partially attributed to gender differences in patient preferences for testing. The hypothesis was that these preferences are influenced by physician recommendations for cardiovascular testing.

METHODS

This was a cohort study of patients who presented to an emergency department (ED) with chest pain. At the time of ED disposition, patients were surveyed to assess whether or not the doctor discussed the possibility of coronary artery disease (CAD), the physician's recommendations for diagnostic testing, and the patient's preferences for further testing. The survey was repeated at the time of discharge from the hospital if the patient was admitted and again at 30 days for all patients. The main outcome was patient-reported physician recommendation for testing, and the secondary outcome was patient preference for cardiovascular testing.

RESULTS

There were 206 patients enrolled (118 women, 88 men). Women were less likely than men to receive cardiac catheterization as inpatients (9.8% vs. 20.0%, p = 0.04). In the ED, women were less likely to be recommended for stress testing (8.5% vs. 19.3%, p = 0.02) or cardiac catheterization (4.2% vs. 13.6%, p = 0.02) or to see a cardiologist (8.5% vs. 22.7%, p < 0.01). As inpatients, women were more likely to be told that no further testing was needed (70.5% vs. 50.0%, p = 0.03). While there was higher incidence of prior CAD and myocardial infarction among the men in the study, analysis after removal of these patients did not alter results. Physicians were less likely to counsel women about diagnostic testing options in the ED (10.1% vs. 22.7%, p = 0.03), as inpatients (11.5% vs. 40.0%, p < 0.01), and as outpatients (26.1% vs. 48.6%, p = 0.04). No patients in the study refused their doctors' recommendations. Women were less likely to prefer catheterization in the ED (5.1% vs. 15.9%, p = 0.01) and were more likely to prefer no further testing as inpatients (60.7% vs. 40.0%, p = 0.02).

CONCLUSIONS

Women who presented to the ED with symptoms concerning for ACS reported lower rates of physician recommendation for cardiovascular testing, as well as lower rates of counseling regarding cardiac etiologies of their chest pain. These findings suggest sex differences in preference for cardiovascular testing may be partially explained by the discussions between women and their doctors.

Lack of sex disparity in cardiovascular testing after coronary computerized tomographic angiography

OBJECTIVES

  The authors assessed whether there was a sex disparity in testing of patients after coronary computerized tomographic angiography (CTA) was performed for emergency department (ED) patients with potential acute coronary syndromes (ACS). In theory, once coronary anatomy has been determined, any disparity in subsequent workup should not be the result of differences in presentation.

METHODS

  This was a prospective cohort study of ED patients who presented with potential ACS and received coronary CTAs at a university hospital. Demographics, history, cardiac risk factors, follow-up testing, and procedures were recorded. Follow-up at 30 days was obtained by structured record review and telephone contact. Patients were stratified by sex and coronary CTA results (max stenosis: none, 1% to 24%, 25% to 49%, 50% to 69%, and ≥70%). Main outcome was the relative risk (RR) of a male receiving a stress test or catheterization within 30 days, stratified by categories of percent maximal stenosis.

RESULTS

  A total of 1,144 patients received coronary CTAs (mean ± SD age = 47.8 ± 8.7 years), 55% were female, and 64% were black or African American. Overall, 161 patients received follow-up testing within 30 days, 113 during their index visit. Men were more likely to receive further testing (RR = 1.51; 95% confidence interval [CI] = 1.14 to 1.99) compared to women. However, when stratified by percentage of stenosis, men were not more likely to receive further testing within 30 days after coronary CTA compared to women (RR = 1.14; 95% CI = 0.68 to 1.91). In multivariable modeling for risk of further testing, stenosis remained significant (adjusted relative risk [aRR] = 1.51; 95% CI = 1.19 to 1.91), while male sex, age, race, and Thrombolysis in Myocardial Infarction (TIMI) risk score were not.

CONCLUSIONS

  Male patients with potential ACS who receive a coronary CTA as a part of their ED evaluation were no more likely than female patients to receive further testing within 30 days.

Sex differences in clinical presentation, management and outcome in emergency department patients with chest pain

OBJECTIVE

We sought to assess sex differences in clinical presentation, management and outcome in emergency department (ED) patients with chest pain, and to measure the association between female sex and coronary angiography within 30 days.

METHODS

We conducted a prospective cohort study in an urban academic ED between Jul. 1, 2007, and Apr. 1, 2008. We enrolled patients over 24 years of age with chest pain and possible acute coronary syndrome (ACS).

RESULTS

Among the 970 included patients, 386 (39.8%) were female. Compared with men, women had a lower prevalence of known coronary artery disease (21.0% v. 34.2%, p < 0.001) and a lower frequency of typical pain (37.1% v. 45.7%, p = 0.01). Clinicians classified a greater proportion of women as having a low (< 10%) pretest probability for ACS (85.0% v. 76.4%, p = 0.001). Despite similar rates of electrocardiography, troponin T and stress testing between sexes, there was a lower rate of acute myocardial infarction (AMI) (4.7% v. 8.4%, p = 0.03) and positive stress test results (4.4% v. 7.9%, p = 0.03) in women. Women were less frequently referred for coronary angiography (9.3% v. 18.9%, p < 0.001). The adjusted association between female sex and coronary angiography was not significant (odds ratio 0.63, 95% confidence interval 0.37-1.10).

CONCLUSION

Women had a lower rate of AMI and a lower rate of positive stress test results despite similar rates of testing between sexes. Although women were less frequently referred for coronary angiography, these data suggest that sex differences in management were likely appropriate for the probability of disease.

Sex bias in cardiovascular testing: the contribution of patient preference

STUDY OBJECTIVE

Women with potential acute coronary syndromes are less likely to receive cardiac catheterization or revascularization than men. We hypothesize that this may be due to different diagnostic test preferences of female and male patients.

METHODS

We conducted a cohort study at 4 emergency departments enrolling patients who presented with symptoms of potential acute coronary syndromes. After hearing the potential benefits and harms of each test, subjects completed a 21-item survey assessing their preference for noninvasive testing versus cardiac catheterization. Based on hypothetical test results, similar questions about medical versus interventional management were asked. Subjects were also queried about likelihood of following physician recommendation for each test or intervention. Actual 30-day testing and interventions were recorded. The main outcome was patient preference about each procedure and the likelihood of patient saying they would accept the physician recommendation.

RESULTS

One thousand eighty patients enrolled; 652 (60%) were admitted to the hospital. With regard to diagnostic test preference, both women and men preferred stress test to catheterization (women 58% versus men 52%; difference 6% [95% confidence interval {CI} -0.06% to 12%]), and the proportion of women and men who would accept the physician recommendation for stress tests was similar (85% for both); however, the stated acceptance rate for cardiac catheterization was lower for women (65% versus 75%; difference -10% [95% CI -15% to -4%]). Women were 6% less likely (67% versus 73%; 95% CI for difference 12% to 0.5%) to accept percutaneous coronary intervention over medical therapy and 7% less likely (61% versus 68%; 95% CI for difference -13% to 1%) to desire coronary artery bypass grafting over medical therapy. The survey results are consistent with the patients' clinical course. During the initial hospitalization, women were less likely to receive diagnostic testing of any type (38% versus 45%; difference -7%; 95% CI for the difference -13% to -1.5%) and cardiac catheterization (10% versus 17%; difference -7% [95% CI -11% to -2%]). Revascularization was infrequent in both groups (4% versus 6%; difference -2% [95% CI -5% to 0.6%]).

CONCLUSION

Although women and men had similar preferences about cardiac diagnostic tests and treatment options, women were less likely than men to say they would accept the physician recommendation for any intervention. Patient preference may partially explain the disparity in cardiovascular testing between women and men.

Influence of sex on the out-of-hospital management of chest pain

BACKGROUND

Sex disparities in the diagnosis and treatment of chest pain or suspected angina have been demonstrated in multiple clinical settings. Out-of-hospital (OOH) care for chest pain is protocol-driven and may be less likely to demonstrate differences between men and women.

OBJECTIVES

The objectives were to investigate the relationship between sex and the OOH treatment of patients with chest pain. The authors sought to test the hypothesis that OOH care for chest pain patients would differ by sex.

METHODS

A 1-year retrospective cohort study of 683 emergency medical services (EMS) patients with a complaint of chest pain was conducted. Included were patients taken to any one of three hospitals (all cardiac referral centers) by a single municipal EMS system. Excluded were patients transported by basic life support (BLS) units, those younger than 30 years, and patients with known contraindications to any of the outcome measures. Multivariable regression was used to adjust for potential confounders. The main outcome was adherence to state EMS protocols for treatment of patients over age 30 years with undifferentiated chest pain. Rates of administration of aspirin, nitroglycerin, and oxygen; establishment of intravenous (IV) access; and cardiac monitoring were measured.

RESULTS

A total of 342 women and 341 men were included. Women were less likely than men to receive aspirin (relative risk [RR] = 0.76; 95% confidence interval [CI] = 0.59 to 0.96), nitroglycerin (RR = 0.76; 95% CI = 0.60 to 0.96), or an IV (RR 0.86; 95% CI = 0.77 to 0.96). These differences persisted after adjustment for demographics and emergency department (ED) evaluation for acute coronary syndrome (ACS) as a blunt marker for cardiac risk. Women were also less likely to receive these treatments among the small subgroup of patients who were later diagnosed with acute myocardial infarction (AMI).

CONCLUSIONS

For OOH patients with chest pain, sex disparities in treatment are significant and do not appear to be explained by differences in patient age, race, or underlying cardiac risk.

Still far to go--an investigation of gender perspective in written cases used at a Swedish medical school

OBJECTIVE

Given decisions to implement a gender perspective in medical education, this study investigated gender perspective in written cases used at a Swedish medical school.

METHOD

All course organizers on terms 5-11 were asked to submit the case descriptions used in 2005. The 257 cases collected were subjected to content analysis focussing on sex of author and patient; whether there were any guidelines for tutors; and whether the case touched on biological sex differences, psychosocial and gender aspects.

RESULTS

The majority of cases were written by male teachers. The proportions of male and female patients were equal. There were instructions for tutors in 20% of the cases. Sex differences were mentioned in 7% of cases. Psychosocial data were meager. Ten cases (4%) contained gender aspects and four of them presented gender as a main issue.

CONCLUSIONS

The lack of instructions for tutors and overall scant interest in psychosocial issues were important obstacles for gender implementation. Actually, ignoring psychosocial conditions means that a gender perspective is also neglected. The results illuminate the importance of monitoring and follow-ups for a successful implementation of gender. Our method of scrutinizing written cases might be useful also for other medical schools.

Gender bias in medicine

Gender bias has implications in the treatment of both male and female patients and it is important to take into consideration in most fields of medical research, clinical practice and education. Gender blindness and stereotyped preconceptions about men and women are identified as key causes to gender bias. However, exaggeration of observed sex and gender differences can also lead to bias. This article will examine the phenomenon of gender bias in medicine, present useful concepts and models for the understanding of bias, and outline areas of interest for further research.

Treatment and outcome in acute myocardial infarction in a community in relation to gender

AIM

To describe treatment and outcome in all patients in a community with acute myocardial infarction (AMI) in relation to gender.

METHODS

All patients discharged from hospital between 2001 and 2002 in Göteborg, Sweden, with a diagnosis of AMI underwent a survey to find possible gender differences. All p-values are age adjusted.

RESULTS

Among 1423 admissions, women comprised 41% and were older than men (mean 79 versus mean 72 years). Women were admitted to a coronary care unit less frequently than men (49% versus 67%; p=0.005). Women underwent coronary angiography less frequently (21% versus 40%; p=0.02). Percutaneous coronary intervention (PCI) was performed in 10% of the women and 18% of the men (p=0.36). Coronary artery bypass grafting (CABG) was performed in 2% of the women and in 9% of the men (p<0.0001). Female gender was associated with a lower risk of reinfarction during first year after hospital discharge (12% versus 16%; p=0.003). The cumulative three-year mortality was 49% in women and 41% in men. However, when adjusting for age, admittance to CCU, coronary angiography and coronary revascularisation, risk of death during 3 years was lower in women than men (odds ratio 0.72; 95% confidence interval 0.60-0.85; p=0.0001).

CONCLUSION

In the community of Göteborg women (mean age 79 years) with AMI are prioritised differently than men (mean age 72 years), prior to admission to a CCU. This results in a less invasive strategy in women, particularly with regard to CABG. When adjusting for difference in age, admittance to CCU and coronary revascularisation female gender was associated with a low risk of death during the subsequent 3 years.
