Psoriasis is independently associated with psychiatric morbidity and adverse cardiovascular risk factors, but not with cardiovascular events in a population-based sample.

BACKGROUND: Psoriasis may significantly reduce quality of life. Previous studies reported an association of psoriasis and cardiovascular risk factors and cardiovascular events. The extent to which psoriasis is associated with psychiatric morbidity and the role of psychiatric comorbidity as a potential confounder of the association between psoriasis and cardiovascular morbidity require further investigation. OBJECTIVES: To study the association between psoriasis, psychiatric morbidity and cardiovascular morbidity. METHODS: Case-control study utilizing an interdisciplinary administrative outpatient database from Germany. Patients with confirmed diagnosis of prevalent psoriasis within the study period (2003-2004) (n = 3147, mean age 57 years) were individually matched for age and gender with 3147 controls without psoriasis. The relationship of psoriasis with psychiatric morbidities (depression, stress-related disorders, behaviour disorders and schizophrenic disorders), cardiovascular risk factors (diabetes, hypertension, obesity and dyslipidaemia) and cardiovascular events [myocardial infarction (MI), stroke] was investigated using logistic and linear regression models. RESULTS: Crude analyses suggested an association of psoriasis with depression, stress-related disorders, behaviour disorders and cardiovascular risk factors, but not with MI [odds ratio (OR) 1.14; 95% confidence interval (95% CI) 0.81-1.62] or stroke (OR 0.97; 95% CI 0.61-1.54). Multivariate models controlling for age, gender and consulting behaviour indicated that psoriasis is independently associated with depression (OR 1.49; 95% CI 1.20-1.86), stress-related disorders (OR 1.41; 95% CI 1.22-1.62), behaviour disorders (OR 1.58; 95% CI 1.05-2.39), diabetes (OR 1.21 95% CI 1.04-1.40), hypertension (OR 1.34; 95% CI 1.18-1.51), dyslipidaemia (OR 1.29; 95% CI 1.07-1.55), and obesity (OR 1.63; 95% CI 1.39-1.90). For each psychiatric condition, the likelihood of being affected significantly increased with each physician visit due to psoriasis, suggesting that the risk of psychiatric comorbidity increases with the severity of psoriasis. CONCLUSION: Psoriasis appears to be independently associated with major psychiatric disorders and with cardiovascular risk factors, but not with cardiovascular events.

Physician, heal Thyself? Regular source of care and use of preventive health services among physicians.

BACKGROUND: Little is known about the regular source of care (RSOC) among physicians, a group whose self-care may reflect the attitudes and recommendations they convey to their patients. METHODS: We performed a cohort study of physicians who graduated from the Johns Hopkins School of Medicine from 1948 through 1964 to identify predictors of not having an RSOC, and to determine whether not having an RSOC was associated with subsequent receipt of preventive services. The RSOC was assessed in a 1991 survey; use of cancer screening tests and the influenza vaccine was assessed in 1997. RESULTS: The response rate in 1991 was 77% (915 respondents); 35% (312) had no RSOC. Internists (odds ratio [OR], 3.26; 95% confidence interval [CI], 1.58-6.74), surgeons (OR, 2.42; 95% CI, 1.17-5.02), and pathologists (OR, 5.46; 95% CI, 2.09-14.29) were significantly more likely to not have an RSOC than pediatricians. Not having an RSOC was inversely related to the belief that health is determined by health professionals (OR, 0.45; 95% CI, 0.29-0.68) and directly related to the belief that chance (OR, 1.90; 95% CI, 1.28-2.82) determines health. Not having an RSOC in 1991 predicted not being screened for breast, colon, and prostate cancer, as well as not receiving an influenza vaccine at 6 years of follow-up. CONCLUSIONS: A large percentage of physicians in our sample had no RSOC, and this was associated with both medical specialty and beliefs about control of health outcomes. Not having an RSOC was significantly associated with failure to use preventive services several years later. Arch Intern Med. 2000;160:3209-3214.

Depression is a risk factor for coronary artery disease in men: the precursors study.

BACKGROUND: Several studies have found that depression is an independent predictor of poor outcome after the onset of clinical coronary artery disease. There are few data concerning depression as a risk factor for the development of coronary artery disease. OBJECTIVE: To determine if clinical depression is an independent risk factor for incident coronary artery disease. PATIENTS AND METHODS: The Johns Hopkins Precursors Study is a prospective, observational study of 1190 male medical students who were enrolled between 1948 and 1964 and who continued to be followed up. In medical school and through the follow-up period, information was collected on family history, health behaviors, and clinical depression. Cardiovascular disease end points have been assessed with reviews of annual questionnaires, National Death Index searches, medical records, death certificates, and autopsy reports. RESULTS: The cumulative incidence of clinical depression in the medical students at 40 years of follow-up was 12%. Men who developed clinical depression drank more coffee than those who did not but did not differ in terms of baseline blood pressure, serum cholesterol levels, smoking status, physical activity, obesity, or family history of coronary artery disease. In multivariate analysis, the men who reported clinical depression were at significantly greater risk for subsequent coronary heart disease (relative risk [RR], 2.12; 95% confidence interval [CI], 1.24-3.63) and myocardial infarction (RR, 2.12; 95% CI, 1.11-4.06). The increased risk associated with clinical depression was present even for myocardial infarctions occurring 10 years after the onset of the first depressive episode (RR, 2.1; 95% CI, 1.1-4.0). CONCLUSION: Clinical depression appears to be an independent risk factor for incident coronary artery disease for several decades after the onset of the clinical depression.

Depression and risk for onset of type II diabetes. A prospective population-based study.

OBJECTIVE: To determine whether depression is associated with an increased risk for onset of diabetes. RESEARCH DESIGN AND METHODS: In 1981, a total of 3,481 household-residing adults participated in the Epidemiologic Catchment Area (ECA) Program survey at the East Baltimore site. A follow-up of that cohort after 13 years completed 1,897 interviews, amounting to > 72% of survivors. In 1981, depression was assessed with the National Institutes of Mental Health (NIMH) Diagnostic Interview Schedule and diabetes, by self-report. This prospective analysis focused on subjects at risk for onset of diabetes by removing from the analysis individuals with diabetes in 1981. RESULTS: There were 89 new cases of diabetes among 1,715 individuals at risk, yielding a 13-year cumulative incidence of diabetes of 5.2%. In logistic models, major depressive disorder, but not milder forms of depression or other forms of psychiatric disorder, predicted the onset of diabetes (estimated relative risk, 2.23; 95% CI 0.90-5.55). Controlling for age, race, sex, socioeconomic status, education, use of health services, other psychiatric disorders, and body weight did not weaken the relationship. CONCLUSIONS: Major depressive disorder signals increased risk for onset of type II diabetes. Limitations of the findings arise from the difficulty in determining temporal order with two chronic conditions, even when the temporal order of measurement is clear. In addition, even though control variables were introduced for the use of health services, it is possible that the treatment for depression led to an earlier diagnosis of diabetes in this sample.

Psychiatric profile and sociodemographic characteristics of adults who report physically abusing or neglecting children.

OBJECTIVE: In this study the authors measured the number of adults in three U.S. communities who reported abusing and neglecting children in their lifetime and assessed the relative impact of sociodemographic characteristics and lifetime diagnosis of mental disorders on both child abuse and child neglect. METHOD: A total of 9,841 respondents, identified through a household sampling procedure for the National Institute of Mental Health (NIMH) Epidemiologic Catchment Area study, were included in the analysis. Self-reported lifetime histories of abuse and neglect of children were measured in the antisocial personality module of the NIMH Diagnostic Interview Schedule. RESULTS: In the study sample, 147 adults (1.49%) stated that they had abused children, and 140 adults (1.42%) stated that they had neglected children. A total of 58.5% of those who reported abuse of children, and 69.3% of those who reported having neglected a child, had a lifetime diagnosis of a mental disorder. Increased odds of reports of both abuse and neglect were associated with having a greater number of children in the household. Low socioeconomic status was a risk factor for neglecting, but not abusing, children. In multivariate analyses, a lifetime history of alcohol disorder was associated with abuse and neglect, affective disorders with abuse, and anxiety disorders with neglecting children. CONCLUSIONS: In light of the associations between mental disorders and mistreatment of children, public health policies designed to prevent child abuse and neglect might be enhanced by an increased focus on interventions targeted at individuals with mental disorders.

Influence of gender, race, and education on patient preferences and receipt of cardiac catheterizations among coronary care unit patients.

The extent to which a preference for less aggressive care explains the lower rate of invasive cardiac services for women and African-Americans is unknown. A prospective observational study of 272 patients admitted to the coronary care unit was conducted at a tertiary referral teaching hospital and a community teaching hospital. In stepwise multivariate analysis, having less than a college education, poor cardiac function, not having undergone a previous cardiac catheterization, being a patient in a nonreferral community hospital, and current smoking were positively associated with a patient's stating that he or she would disagree with a physician's recommendation for a cardiac catheterization. The step-wise multivariate model with cardiac catheterization as the dependent variable indicated that being a patient in a referral medical center, patient willingness to accept a physician's recommendation for a cardiac catheterization, severe heart disease, and having attended high school were predictive. Women did not differ from men in their preference for or receipt of cardiac catheterization. Patients in the coronary care unit with lower levels of education were less likely to undergo cardiac catheterization. This association was only partly explained by less educated patients' being less willing to accept a physician's recommendation to undergo cardiac catheterization.

Validity of physicians' self-reports of cardiovascular disease risk factors.

To determine the accuracy of self-reported risk factors in 78 physicians, self-reported information was compared to findings on a standardized examination. Measured weight (r = 0.98), height (r = 0.95), body mass index (r = 0.96), systolic blood pressure (SBP) (r = 0.72), and diastolic blood pressure (DBP) (r = 0.60) were highly correlated with self-reported values (all P < 0.0001). Mean self-reported SBP and DBP did not differ from measured values; measured weight was 1.5 kg greater and measured height 1.4 cm less than self-reported values (both p < 0.0001). Regression of measured on self-reported values indicated excellent agreement except for DBP and heart rate. Differences between measured and self-reported values were not associated with a variety of variables except for a greater difference in SBP at higher levels of SBP. None of the 60 self-reported nonsmokers had expired carbon monoxide levels greater than 10 ppm. These results indicate that physicians' self-reports of height, body mass index, SBP, and smoking are extremely accurate and suitable for research purposes.

Feasibility of using recipients of health promotional newsletters for post-marketing surveillance.

Achieving an adequate sample size is one of the major difficulties in performing post-marketing observational studies of health outcomes in persons taking specific drug preparations. We assessed the feasibility of recruiting participants for such a study of Cardizem CD from approximately 400,000 U.S. recipients of a health promotion newsletter. A three-page questionnaire was sent to a 2.5% random sample (n = 10,000) of recipients, stratified by geographic region. After two mailings, 2779 (28%) returned the questionnaire. Of the 2779 respondents, 2132 (77%) reported having high blood pressure. Eighty-seven percent indicated a willingness to participate in a long-term prospective study. In a multivariate model, calcium channel blocker (CCB) use was associated with a history of coronary heart disease, duration of hypertension medication use greater than 1 year, a rating of good or excellent hypertension care, higher systolic blood pressure, higher education level, family history of cardiovascular disease, and history of smoking. These results indicate that self-reported CCB users may be at greater risk of cardiovascular heart disease and that it is feasible to use health promotion newsletters as a source of participants in prospective studies of cardiovascular disease.

The current practices of internists in prevention of residential fire injury.

Residential fires are a leading cause of unintentional injury in the United States. We completed a cross-sectional study in an urban internal medicine clinic to describe the patients' risk factors for fire injury and internists' current methods for addressing this health problem. We used a physician self-report survey (n = 301), patient interviews (n = 300), and chart reviews (n = 300) in the evaluation. Among physicians returning the questionnaire (70% response rate), more than 85% demonstrated reasonable knowledge of injury as a major health problem and relatively positive attitudes toward incorporating injury prevention into clinical practice. However, 62% of physicians reported "never" and 23% only "seldom" counseling patients about smoke detectors. Among patients attending the clinic, only 63% reported having a smoke detector in their home. Factors associated with not having a smoke detector through multivariate logistic analysis were black race (odds ratio [OR] = 4.3, confidence interval [CI] = 1.7, 10.6) and patient report that physician did not counsel about smoke detectors (OR = 2.38, Cl = 1.15, 4.90). Age younger than 65 (OR = 1.7, Cl = .93, 2.9) and alcohol abuse (OR 1.5, Cl = .92, 2.5) were borderline in their statistical significance. Eighteen percent of the patients reported being counseled by their physician about smoke detectors, although no documentation appeared in any of the charts. In addition, those patients with risk factors for fire injury did not report being counseled more often than their lower risk counterparts.(ABSTRACT TRUNCATED AT 250 WORDS)

Principles of screening applied to psychiatric disorders.

The morbidity and mortality caused by psychiatric illness is a significant public health problem. The use of a psychiatric screening questionnaire has been one strategy to improve the recognition and treatment of psychiatric disorders in general medical settings. This paper discusses how well psychiatric screening procedures fulfill criteria outlined by the World Health Organization for evaluating the utility of general medical screening efforts. Current research on the utility of screening for psychiatric disorders is reviewed, and the lack of data on the treatment of psychiatric disorders is identified in the general medical sector is emphasized. The randomized clinical trial is offered as the best method to test the efficacy of screening by eliminating various biases outlined in the paper. Quantitative concepts such as positive predictive value and receiver operator characteristic analysis are discussed. The need for more research on the efficacy of early treatment of psychiatric disorders is emphasized.

Recognizing and managing depression in primary care.

Depression is a common disorder in the primary care setting; it is associated with considerable distress and dysfunction. The management of depressed primary care patients can be complicated by the fact that these patients may lack insight into the cause of their symptoms and report only the somatic manifestations of their disorder to their physicians. Primary care patients may also be reluctant to accept a diagnosis of depression or referral to a mental health specialist. Primary care physicians may feel they lack the time or the training to adequately address their patients' depressive disorders. This paper presents a model for identifying, evaluating, and treating depression which has been specifically developed to help primary care physicians overcome these barriers.

The Quality Improvement for Depression collaboration: general analytic strategies for a coordinated study of quality improvement in depression care.

It is difficult to evaluate the promise of primary care quality-improvement interventions for depression because published studies have evaluated diverse interventions by using different research designs in dissimilar populations. Preplanned meta-analysis provides an alternative to derive more precise and generalizable estimates of intervention effects; however, this approach requires the resolution of analytic challenges resulting from design differences that threaten internal and external validity. This paper describes the four-project Quality Improvement for Depression (QID) collaboration specifically designed for preplanned meta-analysis of intervention effects on outcomes. This paper summarizes the interventions the four projects tested, characterizes commonalities and heterogeneity in the research designs used to evaluate these interventions, and discusses the implications of this heterogeneity for preplanned meta-analysis.

Primary care patients' opinions regarding the importance of various aspects of care for depression.

The objectives of this study were to 1) ascertain the importance of various aspects of depression care from the patient's perspective and 2) select items and scales for inclusion in a new instrument to measure primary care patients' attitudes toward and ratings of depression care. We used a cross-sectional survey at a university-based urban primary care clinic; the subjects were adult patients being recruited for a study of minor depression. To help prioritize attitudinal domains, including 126 items identified previously in focus groups, we asked patients to rate the importance of each aspect of depression care on a five-point scale. Items were ranked according to mean scores and the percentage of patients ranking the items as extremely important. The items were selected for inclusion in an instrument to measure patients' attitudes toward depression care based on their importance ratings. We performed reliability and validity testing of scales comprising the 30 most important items and a shortened version that includes 16 items. The sample included 76 patients (mean age 34.8 years; mean CES-D score, 22.2; 72% women; 36% African-American; 32% college graduates). Forty-six percent had visited a mental health professional in the past. The top 30 items for the overall sample came from the following domains: 1) health care providers' interpersonal skills, 2) primary care provider recognition of depression, 3) treatment effectiveness, 4) treatment problems, 5) patient understanding about treatment, 6) intrinsic spirituality, and 7) financial access to services. Scales comprising items from these domains show adequate internal consistency (Cronbach's alpha >0.70) as well as convergent and discriminant validity. We have designed a brief patient-centered instrument for measuring attitudes toward depression care that has evidence for internal item consistency reliability and discriminant validity.

Evaluation of screening schemes for eye disease in a primary care setting.

BACKGROUND AND PURPOSE: Screening in a primary care setting could be an effective method for detection of eye disease. This study was designed to evaluate a questionnaire and a battery of tests for their performance in eye disease screening at a primary care clinic. METHODS: 405 patients aged 40 years or older were interviewed and received a comprehensive eye examination including visual acuity and visual field testing, tonometry, slit-lamp examination, dilated fundus examination and photography. Sensitivity and specificity for the identification of eye disease were calculated for each test and various combinations of tests. RESULTS: A questionnaire-based algorithm for detection of overall eye disease was sufficiently sensitive (90%) but less specific (44%) than an ideal screening test. Distance visual acuity with presenting correction of < or = 20/40 had a sensitivity of 61% and specificity of 72%. A dilated fundus examination had a sensitivity of 79% and specificity of 82%. In screening for glaucoma, tonometry was ineffective (sensitivity = 27% and specificity = 96%), while visual field testing by suprathreshold screening had a sensitivity of 70% and specificity of 67%. Among a variety of combinations, a two-stage strategy with the questionnaire as a first-stage and visual acuity and ophthalmoscopy as second-stage tests provided the best balance of sensitivity (83%) and specificity (76%). CONCLUSION: Among currently available ophthalmic tests, an eye examination including a thorough fundus examination is critical in detection of eye disease. A five-item questionnaire may be useful to identify patients at high risk in primary care practice. More effective tests are needed to improve performance of eye disease screening.

The psychosocial work environment of physicians. The impact of demands and resources on job dissatisfaction and psychiatric distress in a longitudinal study of Johns Hopkins Medical School graduates.

This study examines the relationship between the psychosocial work environment and cross-sectional job dissatisfaction and prospective psychiatric distress in a cohort of Hopkins Medical School graduates in midcareer. An instrument was constructed consisting of five scales: psychological job demands, patient demands, work control, physician resources, and coworker support. The results of scale reliability and factor analysis are presented. Higher job demands were found to be associated with increases in job dissatisfaction and psychiatric distress and greater resources were associated with decreased levels of dissatisfaction and distress. In multiple-regression analysis, only work control and social support were found to be independently associated with dissatisfaction and distress. These results suggest that the presence of control and social support at work protects physicians from developing job dissatisfaction and psychiatric distress.

Screening the public for depression through the Internet.

OBJECTIVE: Despite increased public screening, many individuals with depression remain undetected or untreated. This study explored the performance of an Internet-based program in screening for depression. METHODS: The Centers for Epidemiological Studies Depression (CES-D) scale was adapted as an online screening test. The program advised persons whose score indicated a high probability of depression to seek treatment and asked them to complete a survey of attitudes and preferences that could be printed and taken to a health professional. Responses were collected anonymously for epidemiologic research. Demographic characteristics of participants were compared with those of the U.S. population and participants in previous community screenings. The costs of the program were calculated. RESULTS: The CES-D scale was completed 24,479 times during the eight-month study period. The respondents' median age category was 30 to 45 years, and almost 30 percent were male; 58 percent (N=14,185) screened positive for depression, and fewer than half of those had never been treated for depression. The proportion of younger individuals was larger than in previous public screenings, but was still lower than that in the U.S. population. Our sample contained a lower proportion of minorities than the U.S. population (16.6 percent versus 28.3 percent). Sunk costs totaled $9,000, and additional marginal costs to maintain the system totaled $3,750. CONCLUSIONS: The Internet provides a continuously available, inexpensive, easily maintained platform to anonymously screen a large number of individuals from a broad geographic area. However, older adults and minorities may visit screening sites less frequently than other populations.

Health care financing reform in the United States: the community equity model.

The paper discusses the practical structural aspects required for implementing 'managed competition' reform policy which are often overlooked by policy designers of change. Namely, without fundamentally new organisational structures to mediate among the parties of interest, the policies for change will not be sufficient to meet the future. The paper discusses in some detail an organisational mediating structure called the Community Equity Model which organises care at the local neighbourhood or community level using the community as actual fundsholder. This puts the critical stakeholders in a practical mutual ownership relationship by making allocation, services and resource accountability a local act. The paper briefly discusses the organisational and information technology for this type of health care system redesign.

Home is not where the heart is: looming problems of the home care industry.

This analysis shows a definite trend of fiscal and social retrenchment policy by the government concerning in-home care service delivery (Tables 1 and 2). Ruggie (1990:164) notes that such shifts and changes in Medicare reimbursement patterns may be efforts of the government to realign itself to become the pivotal force in the provision or delivery of in-home care. Cost-containment pressures, although most needed in the health care industry, are the primary driving force behind retrenchment and the subsequent realignment of government. Such forces tend to impede the development of a comprehensive system for the provision of long-term care services. As noted, the movements and shifts in reimbursement patterns documented by this analysis can lead one to conclude that the same old features will continue to prevail instead of new and innovative delivery structures or public-private partnerships. In other words, the in-home care industry will become more like the nursing home industry--highly regulated and perpetually plagued by questions concerning quality of care. Although government is attempting to diminish its task as the prime provider of health services (i.e., through fiscal retrenchment) and the public's role as the dominant delivery system (i.e., social retrenchment), nevertheless the government has been unable to retrench politically in spite of its present direction of cost containment and fiscal restraint. Consequently, Ruggie (1990:147) notes that "the social welfare functions may continue to be performed" in spite of cost restraint policies. As a result, another "no care zone" is created and policy-makers will continue to develop "crisis policy" such as intense demands to hold unit costs low. The home care system has expanded many of the long-term care options and has emerged as a salient segment of our health and social service system (Applebaum and Phillips, 1990). Yet, policy-makers have not developed a comprehensive long-term care system, particularly one that defines a common policy for home care benefits and engenders the right kind of public-private partnership for the delivery of quality home care.
