Influence of age on measurement of health status in patients undergoing elective surgery.
PURPOSE: To assess the influence of age on the relationships between global measures of health and specific health dimensions. DESIGN: Cross-sectional cohort study. SETTING: University tertiary care hospital. PATIENTS: Patients older than 50 years admitted for major elective non-cardiac surgery. MEASUREMENTS: Consenting patients underwent preoperative evaluations including a medical history, physical examination, and administration of health status assessment instruments. Global health status was measured with the Medical Outcomes Study Short Form (SF-36) and with a 0 to 100 verbal measure of global health. Specific health dimensions (physical function, role function, social function, mental health, energy and fatigue, and pain) were measured using the SF-36. Subjects also completed a second validated measure of physical functioning, the Specific Activity Scale (SAS). RESULTS: Although patients aged > 70 years (n = 276) had poorer role function, energy, and fatigue scores and poorer physical function on both the SF-36 and SAS than younger patients (n = 469) (P < 0.05), they had similar overall health perception. In the entire population, global health status as measured with the SF-36 health perception scale had the greatest correlation with the energy and fatigue scale (r = .45), correlated moderately with mental health (r = .35), social function (r = .32), and physical function (r = .33), and correlated less well with the surgically remediable dimension of pain (r = .23). However, correlations of global health perception with pain and global health perception with role functioning were significantly (P < or = 0.05) lower in older patients when compared with subjects 70 years or younger (r = .13 vs .28 and r = .19 vs .33, respectively). CONCLUSION: Despite poorer role function, poorer energy and fatigue scores, and poorer physical function, elderly persons have similar global health perception when compared with younger individuals. These data indicate that global health perception may be determined by different factors in the elderly or that the elderly have fundamentally different expectations of what their global health status should be. Our findings emphasize the importance of multidimensional scales when evaluating quality of life because, particularly in the elderly, the use of global measures alone may not reflect critically important dimension-specific impairments in health.

Bringing comprehensive health education to the New York City Public Schools: a private-public success story.
The New York Academy of Medicine has pioneered a far-sighted effort which successfully introduced two model health education curricula into the New York City Public Schools at both the elementary and middle school levels. The curriculums for kindergarten through sixth grades, Growing Healthy, are currently being used in 525 of New York's 625 elementary schools, and the curriculum for seventh and eighth grades, Being Healthy, is in place in 60 of 200 junior high schools. These curricula offer a comprehensive approach to health education that promotes emotional well-being as well as physical health by improving health behaviors, attitudes, and academic performance of students through hands-on and interactive activities which develop decision-making skills and the ability to make healthful choices. The program has met with ongoing success and expanding influence, as the result of several important factors. First, the New York Academy of Medicine took a leadership role in supporting a venture outside its own walls and became an active advocate for comprehensive health education in the public schools. The Academy's standing as a prestigious yet independent medical association brought influence to the organizing efforts and contributed the credibility needed to get the program off the ground. Second, the Division of Student Support Services of the New York City Public Schools gave strong acceptance and cooperation leading to ongoing financial support and institutionalization of the program. Added to that is the enthusiasm of teachers, administrators, and other in-school personnel who have made the lessons of Growing Healthy and Being Healthy meaningful by reaching hundreds of thousands of students across New York City. Another important factor is the oversight and longevity which has been provided by the unusual gathering of doctors, educators, public health specialists, funders, and city administrators who created an effective private-public coalition 15 years ago and have remained committed to working together. Last through its ongoing efforts, the Academy's Office of School Health Programs has stayed at the forefront of developments in health education. By continuing to evaluate their activities and by constantly integrating new materials into the existing curricular framework, they have demonstrated that a comprehensive health education program can be both meaningful to children and responsive to community needs by reflecting current public health issues and concerns.

Detection and significance of intraoperative and postoperative myocardial ischemia in peripheral vascular surgery.
OBJECTIVE: To determine the incidence and significance of intraoperative and postoperative myocardial ischemia and their relationship to preoperative ischemia and postoperative cardiac events in patients undergoing peripheral arterial surgery. DESIGN: Prospective cohort trial. PATIENTS: One hundred fifteen patients undergoing elective vascular surgery who met predefined eligibility criteria and were thought to have acceptable cardiac risk as assessed by independent cardiologists. INTERVENTIONS: Ambulatory electrocardiographic monitoring preoperatively, intraoperatively, and up to 72 hours postoperatively. MEASUREMENTS: Preoperative clinical characteristics and laboratory data were collected. Predefined adverse cardiac events were identified by an investigator who was "blinded" to monitoring results. Monitor recordings were interpreted for ST-segment depression by investigators blinded to patient information. MAIN RESULTS: Intraoperative ischemia was present in 21 patients (18%), and postoperative ischemia was present in 35 (30%). There were 16 postoperative cardiac events. The relative risk of suffering a cardiac event was 2.7 in patients with intraoperative ischemia and was 16 in patients with postoperative ischemia. Preoperative ischemia closely correlated with intraoperative and postoperative ischemia. Preoperative and postoperative ischemia preceded cardiac events in 14 of 16 patients. CONCLUSIONS: Preoperative ischemia appears to identify high-risk patients, and subsequent perioperative monitoring detects silent ischemia that commonly precedes clinical events and that may be treatable with anti-ischemia therapy.

Cost effectiveness of thrombolytic therapy with streptokinase in elderly patients with suspected acute myocardial infarction.
BACKGROUND: There is a lack of consensus among cardiologists about the potential benefit of thrombolytic therapy for suspected acute myocardial infarction in older patients. To investigate this issue, we constructed a decision-analytic model for patients 75 years of age or older who present with ST-segment elevation within six hours of the onset of symptoms suggesting acute myocardial infarction. METHODS: The variables incorporated in this model were the probability that the patient has an acute myocardial infarction, the probability of in-hospital death among patients with acute myocardial infarction who do not receive thrombolytic therapy, the probability of a fatal or incapacitating complication resulting from thrombolytic therapy, and the expected relative reduction in the risk of death associated with thrombolytic therapy in patients with acute myocardial infarction. Our analyses were based primarily on the use of streptokinase as the thrombolytic agent. RESULTS: Given our base-line assumptions, the probability of dying in the hospital was 21.4 percent if thrombolytic therapy was given and 24.4 percent if it was not given. In one-way sensitivity analyses, thrombolytic therapy decreased the risk of dying if the probability that the patient had an acute myocardial infarction was assumed to be greater than 9 percent, if the probability of dying in the hospital after an acute myocardial infarction without thrombolytic therapy was assumed to be greater than 3 percent, if the rate of fatal or incapacitating complications due to thrombolytic therapy was assumed to be 4 percent or less, or if the relative reduction in the risk of death associated with thrombolytic therapy was assumed to be greater than 1 percent. On the basis of our base-line assumptions, our estimate of the cost effectiveness of streptokinase therapy (the cost per year of life saved) for an 80-year-old patient with suspected acute myocardial infarction was $21,200. For a wide range of assumptions about risks, benefits, and costs, the cost per year of life saved remained less than $55,000. CONCLUSIONS: Within the limitations imposed by the assumptions used in our analysis, thrombolytic therapy with streptokinase was found to be a beneficial and cost-effective treatment for suspected acute myocardial infarction in elderly patients in a wide variety of clinical circumstances.

Long-term survival of emergency department patients with acute chest pain.
To evaluate the long-term prognosis of patients with acute chest pain, prospective clinical data and long-term follow-up data (mean 30.1 +/- 9.4 months) were collected for 1,956 patients who presented to the emergency department of an urban teaching hospital with this chief complaint. During follow-up of the 1,915 patients who were discharged alive from the emergency department or hospital, there were 113 (6%) cardiovascular deaths. No differences were detected in the post-discharge cardiovascular survival rates after 3 years of experience with patients who were discharged from the emergency department with a known prior diagnosis of angina or myocardial infarction (89%) and patients who had been admitted and found to have acute myocardial infarction (85%), angina (87%), or other cardiovascular diagnoses (87%). Patients who were discharged from either the hospital or the emergency department without cardiovascular diagnoses had an excellent prognosis. Multivariate Cox regression analysis identified 5 independent correlates of cardiovascular mortality after discharge: age, prior history of coronary disease, ischemic changes on the emergency department electrocardiogram, congestive heart failure and cardiogenic shock. These findings indicate that the postdischarge cardiovascular mortality of patients with chest pain who are discharged from the emergency department with a known history of coronary disease is similar to that of admitted patients with angina or myocardial infarction. These data suggest that the same types of prognostic evaluation strategies that have been developed for admitted patients with ischemic heart disease should also be considered when such patients present to the emergency department but are not admitted.

Computerized algorithms and pediatricians' management of common problems in a community clinic.
In 1987, a microcomputer clinical algorithm (CA) system for constructing and using CAs for patient care was designed and implemented for six common primary care pediatrics problems. Six community clinic pediatricians agreed to use the system for several months. Length of patient's visit, completeness of data collection, antibiotic use, and appropriateness of clinical plan were measured before the computers were introduced (without CAs) and after the computers were introduced (both with and without CAs). All performance measures improved after the introduction of CAs. However, CA implementation had to be discontinued after five weeks because the CAs were too tedious for the physicians to follow during routine care. The authors conclude that CAs cannot be successfully sustained with physicians for common problems, even though their design and use can significantly improve the process of care.

Development of the 'Activities of Daily Vision Scale'. A measure of visual functional status.
To develop a method for the evaluation of visual function in subjects with cataracts, the authors identified 20 visual activities and categorized them into five subscales (distance vision, near vision, glare disability, night driving, and daytime driving) that comprised the Activities of Daily Vision Scale (ADVS). Each subscale in the ADVS was scored between 100 (no visual difficulty) and 0 (inability to perform the activity because of visual difficulty). In 334 subjects scheduled for cataract extraction (mean age 75 +/- 9 years, 67% women), ADVS scores (mean +/- standard deviation) for each subscale ranged from 44 +/- 31 for night driving to 72 +/- 24 for near vision activities. When administered by telephone, inter-rater reliability coefficients (r) were 0.82 to 0.97 (P < 0.001) for each of the subscales, and test-retest reliability was 0.87 for the scale overall. Cronbach's coefficient alpha was very high for both the in-person (alpha = 0.94) and telephone (alpha = 0.91) formats. Criterion validity, the correlation between visual loss and ADVS score, was -0.37 (P < 0.001) when the ADVS was administered in person and -0.39 (P < 0.001) when it was administered by telephone. Content validity as assessed with factor analysis showed that 88% of the variance of the principal components weighted on one factor. The authors conclude that substantial visual disability is not captured by routine visual testing and that the ADVS is a reliable and valid measure of patient's perception of visual functional impairment.

Cost and health implications of cholesterol lowering.
BACKGROUND: A broad, scientific consensus supports the role of cholesterol as a risk factor for coronary heart disease and agrees that lowering cholesterol levels will reduce coronary heart disease incidence. Cost-effectiveness analysis is a potentially powerful method for measuring the benefits to be achieved by expenditures of health care dollars. METHODS AND RESULTS: The literature related to the effectiveness and cost-effectiveness of cholesterol lowering was reviewed. Application of cost-effectiveness methodology to the question of cholesterol reduction generally supports the use of population-wide educational programs and the aggressive use of cholesterol-lowering therapy for the secondary prevention of subsequent coronary events in persons with preexisting coronary heart disease. For primary prevention, however, therapy with medication has a favorable cost-effectiveness ratio only in identifiable high-risk persons, and the different costs of the various available medications should be taken into account. Therapy with medications, especially for primary prevention, would be more appealing if the price of the available medications were lower. CONCLUSIONS: High priority should be given to research that could validate these cost-effectiveness projections as well as to further studies of the elderly and women, in whom direct data on the precise costs, risks, and benefits of interventions to lower cholesterol remain sparse.
