Gender Disparities in Common Sense Models of Illness Among Myocardial Infarction Victims

Gender differences in symptom misattribution for coronary heart disease symptoms and intentions to seek health care

Women are more likely to delay seeking care for coronary heart disease (CHD) symptoms than men. We tested whether this was because they are more likely to misattribute CHD symptoms. Data were collected in December 2016. Participants were 714 Amazon's Mechanical Turk (crowdsourcing marketplace) workers with US Internet Protocol (IP) addresses; 52% female (ages 35-77 years) made judgments about patients of their same gender described in vignettes. We used adjusted multivariable logistic, ordinal, and linear regression to test our hypotheses. Women had a higher odds of misattributing the symptoms of the target in the vignettes to non-cardiac causes than men (adjusted odds ratio [AOR] = 2.08, p < .001), despite having higher mean knowledge scores about CHD (4.49 vs. 4.03, p < .001) and rating their CHD risk as higher (25% more likely to get CHD vs. 19%, p = .025) than men. Women were also less likely than men to intend to seek care at an emergency department (b = -0.33, p = .024), and if they did intend to seek care, they were more likely to intend to wait to seek care (AOR = 2.37, p = .003). Symptom misattribution may partially account for women's lower likelihood of intending to seek care from an emergency department, which would be especially critical in emergency situations.

Modifiable correlates of illness perceptions in adults with chronic somatic conditions: A systematic review

When individuals become ill, they want to understand and give meaning to their illness. The interpretation of this illness experience, or illness perception, is influenced by a range of individual, contextual, and cultural factors. Some of these factors may be modifiable by nursing interventions. The purpose of this systematic review was to investigate which modifiable factors were correlated with illness perceptions across studies of adults with different chronic somatic diseases. Using search terms tailored to each of four electronic databases, studies retrieved were reviewed by two independent evaluators, and each relevant article was assessed for methodological quality. Results were standardized by calculating correlation coefficients. Fifteen papers on illness perceptions in a variety of chronic diseases met the inclusion criteria. All used standardized measures of illness perceptions. We identified five groups of modifiable correlates of illness perceptions: illness-related factors, psychosocial factors, medication beliefs, information provision and satisfaction with information received, and quality of care. Our findings add to the knowledge of modifiable factors correlated with illness perceptions, including the importance of illness-related factors and psychosocial factors such as anxiety and depression. Knowledge of these correlates can facilitate understanding of patients' illness perceptions and might be useful in tailoring patient education programs.

The Common Sense of Counseling Psychology: Introducing the Common-Sense Model of Self-Regulation

The goal of therapy is typically to improve clients' self-management of their problems, not only during the course of therapy but also after therapy ends. Although it seems obvious that therapists are interested in improving client's self-management, the psychotherapy literature has little to say on the topic. This article introduces Leventhal's Common-Sense Model of Self-Regulation, a theoretical model of the self-management of health, and applies the model to the therapeutic process. The Common-Sense Model proposes that people develop illness representations of health threats and these illness representations guide self-management. The model has primarily been used to understand how people self-manage physical health problems, we propose it may also be useful to understand self-management of mental health problems. The Common-Sense Model's strengths-based perspective is a natural fit for the work of counseling psychologists. In particular, the model has important practical implications for addressing how clients understand mental health problems over the course of treatment and self-manage these problems during and after treatment.

Lay Consultations in Heart Failure Symptom Evaluation

PURPOSE

Lay consultations can facilitate or impede healthcare. However, little is known about how lay consultations for symptom evaluation affect treatment decision-making. The purpose of this study was to explore the role of lay consultations in symptom evaluation prior to hospitalization among patients with heart failure.

METHODS

Semi-structured interviews were conducted with 60 patients hospitalized for acute decompensated heart failure. Chi-square and Fisher's exact tests, along with logistic regression were used to characterize lay consultations in this sample.

RESULTS

A large proportion of patients engaged in lay consultations for symptom evaluation and decision-making before hospitalization. Lay consultants provided attributions and advice and helped make the decision to seek medical care. Men consulted more often with their spouse than women, while women more often consulted with adult children.

CONCLUSIONS

Findings have implications for optimizing heart failure self-management interventions, improving outcomes, and reducing hospital readmissions.

Flawed Self-Assessment

Research from numerous corners of psychological inquiry suggests that self-assessments of skill and character are often flawed in substantive and systematic ways. We review empirical findings on the imperfect nature of self-assessment and discuss implications for three real-world domains: health, education, and the workplace.

In general, people's self-views hold only a tenuous to modest relationship with their actual behavior and performance. The correlation between self-ratings of skill and actual performance in many domains is moderate to meager—indeed, at times, other people's predictions of a person's outcomes prove more accurate than that person's self-predictions. In addition, people overrate themselves. On average, people say that they are “above average” in skill (a conclusion that defies statistical possibility), overestimate the likelihood that they will engage in desirable behaviors and achieve favorable outcomes, furnish overly optimistic estimates of when they will complete future projects, and reach judgments with too much confidence. Several psychological processes conspire to produce flawed self-assessments.

Research focusing on health echoes these findings. People are unrealistically optimistic about their own health risks compared with those of other people. They also overestimate how distinctive their opinions and preferences (e.g., discomfort with alcohol) are among their peers—a misperception that can have a deleterious impact on their health. Unable to anticipate how they would respond to emotion-laden situations, they mispredict the preferences of patients when asked to step in and make treatment decisions for them. Guided by mistaken but seemingly plausible theories of health and disease, people misdiagnose themselves—a phenomenon that can have severe consequences for their health and longevity.

Similarly, research in education finds that students' assessments of their performance tend to agree only moderately with those of their teachers and mentors. Students seem largely unable to assess how well or poorly they have comprehended material they have just read. They also tend to be overconfident in newly learned skills, at times because the common educational practice of massed training appears to promote rapid acquisition of skill—as well as self-confidence—but not necessarily the retention of skill. Several interventions, however, can be introduced to prompt students to evaluate their skill and learning more accurately.

In the workplace, flawed self-assessments arise all the way up the corporate ladder. Employees tend to overestimate their skill, making it difficult to give meaningful feedback. CEOs also display overconfidence in their judgments, particularly when stepping into new markets or novel projects—for example, proposing acquisitions that hurt, rather then help, the price of their company's stock. We discuss several interventions aimed at circumventing the consequences of such flawed assessments; these include training people to routinely make cognitive repairs correcting for biased self-assessments and requiring people to justify their decisions in front of their peers.

The act of self-assessment is an intrinsically difficult task, and we enumerate several obstacles that prevent people from reaching truthful self-impressions. We also propose that researchers and practitioners should recognize self-assessment as a coherent and unified area of study spanning many subdisciplines of psychology and beyond. Finally, we suggest that policymakers and other people who makes real-world assessments should be wary of self-assessments of skill, expertise, and knowledge, and should consider ways of repairing self-assessments that may be flawed.

Gendered symptom presentation in acute coronary syndrome: a cross sectional analysis

BACKGROUND

The international literature suggests that the symptom presentation of acute coronary syndrome may be different for men and women, yet no definitive conclusion about the existence of gendered presentation in ACS has been provided.

OBJECTIVE

This study examines whether gendered symptom presentation exists in a well-defined sample of men and women with ACS.

DESIGN AND SETTING

A cross-sectional analysis of baseline data pertaining to symptom experience and medical profiles were recorded for all ACS patients who participated in a multi-centered randomized control trial, in 5 hospitals, in Dublin, Ireland.

PARTICIPANTS

: Patients were deemed eligible if they were admitted through the Emergency Department (ED) with a diagnosis of ACS, if they were at least 21 years of age and able to read and converse in English. Patients were excluded if they had serious co-morbidities, cognitive, hearing or vision impairment.

METHODS

Patients were interviewed 2-4 days following their ACS event and data was gathered using the ACS response to symptom index.

RESULTS

The study included 1947 patients of whom 28% (n=545) were women. Chest pain was the most commonly experienced symptom in men and women, reported by 71% of patients. Using logistic regression and adjusting for clinical and demographic variables, women had greater odds of experiencing shortness of breath (50% vs 43%; odds ratio [OR]=1.32; 95% CI=1.08-1.62; p=.006) palpitations (5.5% vs 2.8%; OR=2.17; CI=1.31-3.62; p=.003) left arm pain (34% vs 30.5%; OR=1.27; CI=1.02-1.58; p=.03) back pain (7.5% vs 4.8%; OR=1.56; CI=1.03-2.37; p=.034) neck or jaw pain (21.5% vs 13.8%; OR=1.84; CI=1.41-2.40; p=.001) nausea (28% vs 24%; OR=1.30; CI=1.03-1.65; p=.024) a sense of dread (13.4% vs 10.5%; OR=1.47; CI=1.08-2.00; p=.014) and fatigue (29% vs 21.5%; OR=1.64; CI=1.29-2.07; p=.001) than their male counterparts.

CONCLUSIONS

Although chest pain is the most commonly experienced symptom by men and women, other ACS symptomology may differ significantly between genders.

The model of pathways to treatment: conceptualization and integration with existing theory

BACKGROUND

Studying and understanding pathways to diagnosis and treatment is vital for the development of successful interventions to encourage early detection, presentation, and diagnosis. An existing framework posited to describe the decisional and behavioural processes that occur prior to treatment (Andersen et al.'s General Model of Total Patient Delay) does not appear to match the complex and dynamic nature of the pathways into and through the health care system or provide a clear framework for research. Therefore a revised descriptive framework, the Model of Pathways to Treatment, has been proposed.

PURPOSE

This paper presents the concepts and definitions of the Model of Pathways to Treatment and specifies how the model can encompass existing psychological theory, with particular focus on the Appraisal and Help-seeking intervals. The potential and direction for future work is also discussed.

STATEMENT OF CONTRIBUTION

WHAT IS ALREADY KNOWN ON THIS SUBJECT?: • The use of theory is often lacking in existing research into delays in presentation, diagnosis and treatment of illness. WHAT DOES THIS STUDY ADD?: • A detailed account of the concepts and definitions of a revised framework: the Model of Pathways to Treatment. • Specification of how the Model of Pathways to Treatment can encompass existing psychological theory such as the Common Sense Model of Illness Self-regulation and Social Cognitive Theory.

Sex differences in patient-reported symptoms associated with myocardial infarction (from the population-based MONICA/KORA Myocardial Infarction Registry)

Many studies have examined gender-related differences in symptoms of acute myocardial infarction (AMI). However, findings have been inconsistent, largely because of different study populations and different methods of symptom assessment and data analysis. This study was based on 568 women and 1,710 men 25 to 74 years old hospitalized with a first-ever AMI from January 2001 through December 2006 recruited from a population-based AMI registry. Occurrence of 13 AMI symptoms was recorded using standardized patient interview. After controlling for age, migration status, body mass index, smoking, some co-morbidities including diabetes, and type and location of AMI through logistic regression modeling, women were significantly more likely to complain of pain in the left shoulder/arm/hand (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.10 to 1.69), pain in the throat/jaw (OR 1.78, 95% CI 1.43 to 2.21), pain in the upper abdomen (OR 1.39, 95% CI 1.02 to 1.91), pain between the shoulder blades (OR 2.22, 95% CI 1.78 to 2.77), vomiting (OR 2.23, 95% CI 1.67 to 2.97), nausea (OR 1.94, 95% CI 1.56 to 2.39), dyspnea (OR 1.45, 95% CI 1.17 to 1.78), fear of death (OR 2.17, 95% CI 1.73 to 2.72), and dizziness (OR 1.49, 95% CI 1.16 to 1.91) than men. Furthermore, women were more likely to report >4 symptoms (OR 2.14, 95% CI 1.72 to 2.66). No significant gender differences were found in chest pain, feelings of pressure or tightness, diaphoresis, pain in the right shoulder/arm/hand, and syncope. In conclusion, women and men did not differ regarding the chief AMI symptoms of chest pain or feelings of tightness or pressure and diaphoresis. However, women were more likely to have additional symptoms.

Temporal trends in patient and treatment delay among men and women presenting with ST-elevation myocardial infarction

BACKGROUND

over the last decade, there have been major changes in the treatment of ST-elevation myocardial infarction (STEMI). Whether these have resulted in changes in sex differences in time to treatment is unknown. We examined temporal trends in time to reperfusion therapy among men and women with STEMI.

METHODS

the study includes 2 cohorts of STEMI patients presenting to a large metropolitan region during the periods August 24, 2000, to August 20, 2002 (Cohort1, n = 753), and August 25, 2006, to December 31, 2008 (Cohort2, n = 885).

RESULTS

in both cohorts, compared with men, women were significantly older and had more comorbidities. Rate of emergency medical services use among women increased from 55% in Cohort1 to 66% in Cohort2 (P = .02). Median time from symptom onset to first medical contact was 84 minutes among men and 121 minutes among women (P < .01) in Cohort1 and 59 minutes among men and 81 minutes among women (P < .01) in Cohort2. Median door-to-balloon time was significantly longer among women compared with men in Cohort2. After multivariable adjustment, female sex was associated with a 34% (or 27-minute) increase in time from symptom onset to first medical contact and with a 23% (or 13-minute) increase in time from hospital arrival to reperfusion therapy.

CONCLUSIONS

in the last decade, there have been significant reductions in patient and system delay, especially among women. However, women continue to have longer presentation and treatment times, suggesting that there continue to be opportunities for improvement.

Gaps between patients, media, and academic medicine in discourses on gender and depression: a metasynthesis

For reasons that are not yet fully understood, depression affects women twice as often as men. In this article we describe an investigation of how depression is understood in relation to men and women by the patients themselves, the media, and the medical research establishment. We do this by undertaking a metasynthesis of data from three different sources: interviews with depressed patients, media portrayals of depressed individuals in Sweden, and international medical articles about depression. The findings reveal that there are differences in (a) the recognition of depression, (b) the understanding of the reasons for depression, and (c) the contextualization of depression. Although women and men describe different symptoms and reasons for falling ill, these gendered expressions are not acknowledged in articles coming from Western medical settings. We discuss the implications of these findings and conclude that an integrated model for understanding biological, gender, and cultural aspects of depression has yet to be developed.

Influence of Assessment Methods on Reports of Gender Differences in AMI Symptoms

The purpose of this secondary analysis was to compare gender differences in retrospective reports of acute myocardial infarction (AMI) symptoms resulting from two different assessment methods: the open-ended inquiry and the combined assessment approach. Women reported more atypical symptoms in their responses to the open-ended inquiry and a greater number of typical, atypical, and total symptoms in the combined assessment approach in which the open-ended inquiry was followed by a series of closed-ended questions. Women reported more jaw/neck pain, dyspnea, and palpitations in response to the open-ended inquiry. In the combined assessment, men reported more chest pain/discomfort than women, whereas women were more likely to report jaw/neck pain, dyspnea, back pain, fatigue, paroxysmal nocturnal dyspnea, and palpitations. The data suggest that careful attention to the type of questions used to assess AMI symptoms could lead to more definitive conclusions regarding gender differences in AMI symptoms.

Sex differences in patients seeking medical attention for prodromal symptoms before an acute coronary event

BACKGROUND

Patients with acute coronary syndromes (ACS) may experience nonspecific prodromal symptoms before their cardiac event. We used population-level data to determine the rate at which such patients seek medical attention for these symptoms, whether sex differences are present, and if an association between prodromes and 1-year mortality exists.

METHODS

All patients with ACS in Alberta, Canada, between April 1, 1999, and March 31, 2001, were included. Prodromes reported during all physician visits in the 90 days before ACS presentation consisted of (1) pain (chest, arm, shoulder, neck, jaw, throat, or leg); (2) anxiety/fatigue; (3) gastrointestinal disturbances; (4) head-related conditions (dizziness, headache, visual disturbances); and (5) other (sweating, shortness of breath, heart racing, cough, numbness).

RESULTS

Of 14,230 patients with ACS, 2,268 (15.9%, 45.6% women) sought medical attention for at least one prodrome, with pain and anxiety/fatigue most common. Prodromes were associated with increased cardiac investigations before ACS in both sexes. After adjustment for baseline characteristics, a significant interaction between sex and prodromes was found (P [interaction] = .011). Prodromes were associated with improved 1-year survival in women (adjusted hazard ratio [HR] 0.74, 95% CI 0.58-0.95, P = .016, risk-adjusted mortality 8.7% vs 11.1% [without prodromes], P < .001) but not in men (adjusted hazard ratio 0.92, 95% CI 0.76-1.12, P = .422, 9.9% [with prodromes] vs 9.1% [without prodromes], P = .358).

CONCLUSIONS

A small proportion of patients with ACS seek medical attention for prodromal symptoms in the 90 days before ACS. Seeking help for these symptoms is associated with improved survival in women but not in men.

Health disparities in 30 indicators of recommended clinical care

This article examines variations in clinical practice for 30 clinical indicators. Patients' age, gender, and morbidity and certain characteristics of their physicians affected whether they received recommended care. Recommended care increased with patient age for 13 significant clinical indicators and decreased with age for 7 others. Males received recommended care more often for 12 of 13 clinical indicators. Recommended care varied by physician specialties for health screenings, disease management, and medication use. Patients seeing physicians who treated a high volume of patients generally received better care. The variations in recommended care suggest potential targets for healthcare quality improvements.

Symptom presentation and time to seek care in women and men with acute myocardial infarction

BACKGROUND

Leventhal's common sense model of illness representation was used to examine symptom presentation, time to seek care, and expectations about the experience of having an acute myocardial infarction (AMI).

HYPOTHESES

(1) Women with AMI will report a different symptom set than men, (2) women's expectations about AMI, for level of risk and symptoms, will be different than men's, (3) women will take longer to seek care than men, and (4) as suggested by the common sense model, a match between expected and actual symptoms will be related to shorter time to seek care.

METHOD

A descriptive, correlational design was used. Thirty woman and 30 men diagnosed with AMI or an evolving MI treated with thrombolytic therapy or primary percutaneous coronary intervention were interviewed using the Symptom Representation Questionnaire.

RESULTS

Gender differences in symptom presentation were limited. The majority of women and men reported that their symptoms were different from what they expected an AMI would be like. Most stated that their pain was less than expected, whereas some reported either the location of discomfort or associated symptoms as different then expected. There was no gender difference in time to seek care. Logistic regression and survival analysis demonstrated that participants who reported a match between symptoms expected and actual symptoms experienced arrived in the emergency department sooner than those whose symptoms did not match their expectations.

CONCLUSION

The findings provide support for the use of the common sense model to explain care-seeking behavior in AMI.

Women with myocardial infarction are less likely than men to experience chest symptoms

OBJECTIVES

To assess similarities and differences between women and men regarding experience and interpretation of symptoms of acute myocardial infarction before hospital admission.

DESIGN

149 women and 384 men responded to a questionnaire two weeks after hospital discharge.

RESULTS

Men were more likely than women to report chest symptoms. Women were more likely to complain of nausea, palpitations, dyspnoea, fainting, pain in the back and pain between the scapulas than men. Irrespective of sex only half the patients interpreted their symptoms as cardiac. Early onset of chest symptoms, previously diagnosed angina, symptoms in accordance with expectations, symptoms stronger than expected and familiarity with symptoms, all contributed to a cardiac attribution among both sexes. A diagnosis of hypercholesterolemia and prescribed nitroglycerin was related to a cardiac attribution among men only.

CONCLUSION

Women were less likely to experience chest symptoms and more likely to experience atypical symptoms than men. Symptom experience and the patients' expectations of symptoms influenced interpretation and attribution among both sexes.

Depression and prehospital delay in the context of myocardial infarction

OBJECTIVE

The purpose of this study was to evaluate how depression might influence treatment-seeking behaviors in the context of evolving symptoms of myocardial infarction (MI).

METHODS

Post-MI patients (n = 433) completed a retrospective self-report measure of depressive symptoms with regard to the 2 weeks preceding the MI and a semistructured interview regarding their treatment-seeking behaviors.

RESULTS

Survival analyses found that delay in seeking treatment for acute MI symptoms was observed among participants who (1) attributed their symptoms to noncardiac causes, (2) perceived their symptoms to be relatively mild, (3) experienced gastrointestinal distress, (4) did not experience sweating, and (5) reported being depressed during the 2 weeks before hospitalization. Subsidiary analyses indicated that, among depressive symptoms, sleep disturbance and fatigue predicted delay.

CONCLUSION

Depression warrants further attention as a variable that may influence treatment seeking for MI symptoms. Results highlight the need to adequately screen for and treat depression among persons at risk for MI.

State of disparities in cardiovascular health in the United States

BACKGROUND

Reducing health disparities remains a major public health challenge in the United States. Having timely access to current data on disparities is important for policy and program development. Accordingly, we assessed the current magnitude of disparities in cardiovascular disease (CVD) and its risk factors in the United States.

METHODS AND RESULTS

Using national surveys, we determined CVD and risk factor prevalence and indexes of morbidity, mortality, and overall quality of life in adults > or =18 years of age by race/ethnicity, sex, education level, socioeconomic status, and geographic location. Disparities were common in all risk factors examined. In men, the highest prevalence of obesity (29.2%) was found in Mexican Americans who had completed a high school education. Black women with or without a high school education had a high prevalence of obesity (47.3%). Hypertension prevalence was high among blacks (39.8%) regardless of sex or educational status. Hypercholesterolemia was high among white and Mexican American men and white women in both groups of educational status. Ischemic heart disease and stroke were inversely related to education, income, and poverty status. Hospitalization was greater in men for total heart disease and acute myocardial infarction but greater in women for congestive heart failure and stroke. Among Medicare enrollees, congestive heart failure hospitalization was higher in blacks, Hispanics, and American Indians/Alaska Natives than among whites, and stroke hospitalization was highest in blacks. Hospitalizations for congestive heart failure and stroke were highest in the southeastern United States. Life expectancy remains higher in women than men and higher in whites than blacks by approximately 5 years. CVD mortality at all ages tended to be highest in blacks.

CONCLUSIONS

Disparities in CVD and related risk factors remain pervasive. The data presented here can be invaluable for policy development and in the planning, implementation, and evaluation of interventions designed to eliminate health disparities.

What's wrong with me? Women's coronary heart disease diagnostic experiences

Most women are unaware that that they may experience atypical coronary heart disease (CHD) symptoms. Women's atypical presentation often results in women having difficulty being diagnosed with CHD or myocardial infarction. Investigating women's CHD diagnostic experiences may reveal vital areas amenable to intervention. This secondary analysis explored women's CHD diagnostic experiences. Forty women completed in-depth interviews in their homes that were audiotaped and lasted 2-3 hours. Using content analysis and constant comparison, five themes emerged: awareness, seeking treatment, frustration, treatment decisions, and anger. Despite numerous symptoms and visits with clinicians, most women were not diagnosed with CHD before myocardial infarction. During the infarction, women with typical symptoms were easily diagnosed while those with atypical symptoms received a delayed diagnosis. Those who repeatedly sought treatment were angry about not being diagnosed earlier. Further research is needed to promote early symptom recognition, timely diagnosis, and efficacious treatment-keys to improving women's CHD outcomes and to preventing similar negative diagnostic experiences.

Gender differences in patients' attributions for myocardial infarction: implications for adaptive health behaviors

Attributions for myocardial infarction were studied in a patient sample (N = 157). Men and women were comparable at intake on age, health status, and lifestyle factors. Attributions to diet, chi2 (1, N = 157) = 8.83, p = .003, and exercise, chi2 (1, N = 157) = 6.60, p = .01, were less common among women than men. After 3 months (n = 136), women were less likely than men to report improving their diets or increasing exercise. Initial attributions predicted subsequent reports of behavior change in relevant domains. These findings suggest that gender differences in causal attributions for myocardial infarction may contribute to subsequent differences between men and women in health-related behavior change.
