A telecommunications system to manage patients with chronic disease.

The care of patients with chronic disease is a large and growing problem in the United States and other industrialized countries.' it is expensive, and the quality of care received by patients is often sub-optimal, resulting in poor health outcomes. We developed a totally automated computer-controlled telecommunications system, called TLC, that provides--frequent, close monitoring of patients with chronic disease and reports the results to the patients' physicians on a timely basis, so that they can intervene appropriately. TLC also monitors the patients' important self care activities, such as medication-taking, and provides education and counseling to improve the patients' performance of these activities. The system operates through regularly scheduled telephone conversations with patients' in their homes. An evaluation of a TLC chronic disease application for patients with hypertension demonstrated that use of the system was associated with significant improvement of the patients' adherence to their medication regimens and significantly improved blood pressure control. These results show that it is possible to design an information science-based health care delivery system that performs functions usually performed only by health care professionals, and suggests that information science will become an important means of delivering health care services in the next millennium.

[The functional activity of the thrombocytes in chronic diseases of the large intestine].

Chronic diseases of the large intestine--catarrhal colitis, colonic stasis, unspecific ulcerative colitis, and amebiasis of the large intestine are attended by marked changes in the functional activity of blood platelets and factors of its regulation. They reflect the dynamics of the disease before and after operative and nonoperative treatment. A recurrence of the disease is linked with activation of blood platelets. Trental and contrycal are used for correction of the disorders, which improves the condition of some of the patients. The authors discuss the importance of biogenic amines, cAMP, and functional activity of the blood platelets as universal mechanisms of the development of chronic diseases of the large intestine.

[Estimates and trends of obesity prevalence through mortality rates associated of chronic diseases in Mexico].

The pandemy of obesity is affecting more than 300 millions of adults in the world. The trend is increasing. Diabetes, coronary hearth disease, hypertension, cerebrovascular disease and dyslipidemia are chronic diseases associated with obesity. The methodology of this paper is proposed as an alternative resource based in mortality data to quantify the magnitude of chronic diseases in developing countries. Deaths for Mexico registered in 2000, according to selected causes, were taken to derive indirectly the prevalence of obesity in years 2000, 2005, and 2010, both males and females > or = 35 years-old. In 2010, an estimation of 8 million of Mexican with obesity is made. This methodology is referred to be probed in the quantification and projection of chronic diseases. According with our estimation, we hope in Mexico at 2010 to have between 8 and 14 millions of people > or = 35 years-old with obesity.

The burden of chronic disease.

The shift from acute infectious and deficiency diseases to chronic noncommunicable diseases is not a simple transition but a complex and dynamic epidemiological process, with some diseases disappearing and others appearing or reemerging. The unabated pandemic of childhood and adulthood obesity and concomitant comorbidities are affecting both rich and poor nations, while infectious diseases remain an important public health problem, particularly in developing countries. More attention should be given to the high burden of disease associated with soil-transmitted helminths and schistosomiasis, which until recently was not considered a priority even though regular drug treatment is obtainable at relatively little cost. In developing countries, the pressing requirement is to provide an accessible and good quality health-care system, whereas industrialized countries have a major need for greater public health education and the promotion of healthy life-styles.

Chronic disease mortality among Wisconsin Native American Indians, 1984-1993.

Premature chronic disease mortality continues to be a problem among American Indian populations. To document the chronic disease burden in the Wisconsin American Indian population, age- and sex-specific incidence-density mortality rates for ten chronic diseases (ischemic heart disease, stroke, diabetes, chronic obstructive pulmonary disease, cirrhosis, and cancer of the breast, cervix, lung, colorectum and prostate) were estimated for a 10-year period (1984-1993) and compared with the Wisconsin non-Hispanic white population. Compared with whites, American Indians had markedly higher mortality rates from diabetes and cirrhosis in all age- and sex-specific groups. Ischemic heart disease mortality was significantly greater in both American Indian men and women 45-64 years of age (Rate Ratio [RR] = 1.7 and 2.1, respectively) compared to whites of the same age, but was lower in American Indians 65 years of age or older (RR = 0.9 for both sexes). Overall, these ten chronic diseases were responsible for a significant excess number of deaths in middle-aged American Indian men and women (i.e., 45-64 years of age), whereas the chronic disease mortality experience of older American Indian men and women (i.e., > or = 65 years of age) was similar to that of the older white population. Diabetes and cirrhosis were the most important causes of increased mortality overall; however, ischemic heart disease was responsible for a large number of excess deaths in middle-aged American Indian men and women.

Safety of and serum antibody response to cold-recombinant influenza A and inactivated trivalent influenza virus vaccines in older adults with chronic diseases.

Forty older adults with chronic diseases were vaccinated intranasally with either influenza A/California/10/78 (H1N1) (CR37) or influenza A/Washington/897/80 (H3N2) (CR48) virus. No clinically significant morbidity or decrement in pulmonary function occurred postvaccination. Two (15%) recipients of CR37 virus and twelve (44%) recipients of CR48 virus became infected with vaccine virus, as indicated by a fourfold rise in serum hemagglutination inhibition antibody titer; a fourfold rise in serum immunoglobulin G (IgG) or IgA antibody titer, indicated by enzyme-linked immunosorbent assay; isolation of vaccine virus from nasal washings; or all of these. Within 1 year after cold-recombinant vaccine virus vaccination, 18 vaccines received inactivated trivalent influenza virus vaccine parenterally. Of the vaccinees, 13 (72%) developed a fourfold rise in serum antibody titer to H1N1 antigen and 16 (89%) developed a fourfold rise in serum antibody titer to H3N2 antigen. We conclude that administration of these cold-recombinant vaccine viruses to older adults with chronic diseases was safe, but that serum antibody response rates were lower than those achieved with subsequently administered inactivated influenza virus vaccine given parenterally. However, the higher seroconversion rates attained by using the inactivated trivalent influenza virus vaccine do not necessarily mean that it is more efficacious in preventing infection or severe illness or both due to natural wild-type influenza A virus.

Consultation rates and incidence of intercurrent morbidity among patients with chronic disease in general practice.

BACKGROUND: Information on frequency of consultation and presented morbidity among patients with chronic disease is relevant to the management of these patients in view of the increasing prevalence of chronic diseases. AIM: This study set out to examine consultation rates and incidence of intercurrent morbidity in general practice in cohorts of patients with five common chronic diseases: hypertension, chronic ischaemic heart disease, diabetes mellitus, chronic respiratory disease and osteoarthritis. METHOD: In seven practices with 15 general practitioners the records of all patients were screened for inclusion in the study. The data used for analysis were from 962 patients, whose diagnoses were made in agreement with diagnostic criteria, who were not under specialist care, and who were followed up for 21 months. A distinction was made between patients with one, or two or more of the five chronic diseases studied. For the single disease subgroups of patients with hypertension or diabetes two reference groups of people without a chronic disease, standardized for age and sex, were identified from the population in the same practices. RESULTS: Consultation rates were higher for patients with comorbidity than for patients with a single disease. Intercurrent diseases were presented more frequently to the general practitioner by patients with comorbidity than by patients with a single disease. Most intercurrent morbidity consisted of acute common diseases such as myalgia, upper respiratory tract infection and urinary tract infection. Patients with only hypertension or only diabetes had higher consultation rates than the corresponding reference group but did not have higher total incidence rates of intercurrent morbidity. CONCLUSION: Patients with chronic disease consult their general practitioner frequently, and patients with more than one chronic disease consult even more frequently. The general practitioner has to deal with chronic disease and intercurrent acute disease in a single patient.

A chronic disease score with empirically derived weights.

Different types of medication prescribed during a 6-month period for the treatment and management of chronic conditions were utilized in the refinement and validation of a chronic disease score. Prescription data, in addition to age and sex, were utilized to develop a chronic disease score based on empirically derived weights for each of three outcomes: total cost, outpatient cost, and primary care visits. The ability of the revised chronic disease score to predict health care utilization, costs, hospitalization, and mortality was compared to an earlier version of the chronic disease score (original) that was derived through clinical judgments of disease severity. The predictive validity of the chronic disease score is also compared to ambulatory care groups, which utilize outpatient diagnoses to form mutually exclusive diagnostic categories. Models based on a concurrent 6-month period and a 6-month prospective period (ie, the 6-month period after the chronic disease score or ambulatory care group derivation period) were estimated using a random one half sample of 250,000 managed-care enrollees aged 18 and older. The remaining one half of the enrollee population was used as a validation sample. The revised chronic disease score showed improved estimation and prediction over the original chronic disease score. The difference in variance explained prospectively by the revised chronic disease score versus the ambulatory care groups, conversely, was small. The revised chronic disease score was a better predictor of mortality than the ambulatory care groups. The combination of revised chronic disease score and ambulatory care groups showed only marginally greater predictive power than either one alone. These results suggest that the revised chronic disease score and ambulatory care groups with empirically derived weights provide improved prediction of health care utilization and costs, as well as hospitalization and mortality, over age and sex alone. We recommend the revised chronic disease score with total cost weights for general use as a severity measure because of its relative advantage in predicting mortality compared to the outpatient cost and primary care visit weights.

The influence of chronic disease on resource utilization in common acute pediatric conditions. Financial concerns for children's hospitals.

OBJECTIVES: To estimate the resource utilization in hospitalizations for common pediatric conditions or procedures involving patients with chronic disease vs those with no chronic disease and to develop an economic model of hospital per-patient profit (or loss) when insurance contracts fail to account for the presence of chronic disease. SETTING AND DESIGN: A retrospective analysis of selected acute pediatric conditions found in the 1991 and 1992 MedisGroups National Comparative Data Base. PATIENTS: We studied 30379 pediatric admissions for common acute conditions, including concussion, croup, pneumonia, appendicitis, gastroenteritis, fractures, cellulitis, urinary tract infection, and viral illness. MAIN OUTCOME MEASURES: Hospital length of stay and total hospital charges. RESULTS: For patients without chronic disease, mean (geometric) length of stay was 2.53 vs. 3.05 days (P<.001) for patients with at least 1 chronic disease. For patients without chronic disease, mean (arithmetic) total hospital charge was S2614 vs. $3663 (P<.001) for patients with at least 1 chronic disease. Assuming 75% of patients with chronic disease are admitted to a children's hospital vs 25% to a general hospital, overall loss per patient at the children's hospital ranged between 1.5% and 2.9%, depending on assumptions regarding cost-to-charge ratios and the treatment of charge outliers. Pneumonia cases were associated with a 4.0% to 5.85% loss. CONCLUSIONS: Length of stay and charges are higher for everyday pediatric conditions or procedures when patients also have a chronic disease. If insurance contracts fail to account for chronic disease, then children's hospitals will realize significant financial losses, and over time this will lead to a decline in their financial viability, a reduction in quality, or a change in their mission.

Peripheral vascular disease: educational concerns for patients with a chronic disease in a changing health-care environment.

Education about vascular disease requires information to change habits related to diet, activity, and personal health. Uncertainty significantly impacts the ability of individuals with a chronic disease to feel secure in treatment programs. A clear understanding of the disease, mutual development of measurable goals, clear communication, and a commitment to change provide the format for a successful education and prevention program. As the health-care system expects each individual to assume more responsibility for health promotion and maintenance, education will be key.

Process, rationale, and interventions of Pakistan's National Action Plan on Chronic Diseases.

Most developing countries do not comprehensively address chronic diseases as part of their health agendas because of lack of resources, limited capacity within the health system, and the threat that the institution of national-level programs will weaken local health systems and compete with other health issues. An integrated partnership-based approach, however, could obviate some of these obstacles. In Pakistan, a tripartite public-private partnership was developed among the Ministry of Health, the nongovernmental organization (NGO) Heartfile, and World Health Organization. This was the first time an NGO participated in a national health program; NGOs typically assume a contractual role. The partnership developed a national integrated plan for health promotion and the prevention and control of noncommunicable diseases (NCDs), which as of January 2006 is in the first stage of implementation. This plan, called the National Action Plan on NCD Prevention, Control, and Health Promotion (NAP-NCD), was released on May 12, 2004, and attempts to obviate the challenges associated with addressing chronic diseases in countries with limited resources. By developing an integrated approach to chronic diseases at several levels, capitalizing on the strengths of partnerships, building on existing efforts, and focusing primary health care on chronic disease prevention, the NAP-NCD aims to mitigate the effects of national-level programs on local resources. The impact of the NAP-NCD on population outcomes can only be assessed over time. However, this article details the plan's process, its perceived merits, and its limitations in addition to discussing challenges with its implementation, highlighting the value of such partnerships in facilitating the missions and mandates of participating agencies, and suggesting options for generalizability.

Use of complementary and alternative medicine among adults with chronic diseases: United States 2002.

BACKGROUND: Use of Complementary and Alternative Medicine (CAM) has increased in recent years. OBJECTIVE: The aim of this study was to determine the use of CAM among people with diagnosed chronic diseases. DESIGN: Cross-sectional analysis was used. SETTING: The 2002 National Health Interview Survey was the setting. PATIENTS: Participants were representative of the noninstitutionalized U.S. population 18 years and older. MEASUREMENTS: Respondents answered questions about use of CAM and physician-diagnosed arthritis, cancer, cardiovascular disease, diabetes, and lung disease. RESULTS: Adults with diagnosed chronic diseases are more likely to use CAM compared to adults with none of the reported chronic diseases. Adults with arthritis alone were most likely to report ever use of CAM (59.6%) followed by adults with cancer or lung disease alone or two or more chronic diseases (55%), adults with cardiovascular disease (46.4%), and adults with no chronic diseases (43.6%) and diabetes alone (41.4%). Adults with chronic diseases were also more likely to report use of CAM in the past 12 months (32% to 43.3%), followed by adults with none of these chronic diseases (32%), and adults with diabetes alone (26.2%). Less than 30% of CAM users in the past 12 months reported talking to their healthcare professional about CAM use. LIMITATIONS: Information about CAM use is based on self-report. CONCLUSIONS: Use of CAM, particularly biologically based CAM therapies, is common and is more likely to be used by those with chronic diseases.

A chronic disease score from automated pharmacy data.

Using population-based automated pharmacy data, patterns of use of selected prescription medications during a 1 year time period identified by a consensus judgement process were used to construct a measure of chronic disease status (Chronic Disease Score). This score was evaluated in terms of its stability over time and its association with other health status measures. In a pilot test sample of high utilizers of ambulatory health care well known to their physicians (n = 219), Chronic Disease Score (CDS) was correlated with physician ratings of physical disease severity (r = 0.57). In a second random sample of patients (n = 722), its correlation with physician-rated disease severity was 0.46. In a total population analysis (n = 122,911), it was found to predict hospitalization and mortality in the following year after controlling for age, gender and health care visits. In a population sample (n = 790), CDS showed high year to year stability (r = 0.74). Based on health survey data, CDS showed a moderate association with self rated health status and self reported disability. Unlike self-rated health status and health care utilization, CDS was not associated with depression or anxiety. We conclude that scoring automated pharmacy data can provide a stable measure of chronic disease status that, after controlling for health care utilization, is associated with physician-rated disease severity, patient-rated health status, and predicts subsequent mortality and hospitalization rates. Specific methods of scoring automated pharmacy data to measure global chronic disease status may require adaptation to local prescribing practices. Scoring might be improved by empirical estimation of weighting factors to optimize prediction of mortality and other health status measures.

Health literacy and knowledge of chronic disease.

We sought to examine the relationship between health literacy and knowledge of disease among patients with a chronic disease. A total of 653 new Medicare enrollees aged 65 years or older who had at least one chronic disease (115 asthma, 266 diabetes, 166 congestive heart failure, 214 hypertension), completed both the in-person and telephone survey. Health literacy measured by the short test of functional health literacy in adults (S-TOFHLA) and demographic information were collected during the in-person survey. Knowledge of disease was assessed by questions based on key elements in educational materials during a telephone survey. Overall, 24% of patients had inadequate and 12% had marginal health literacy skills. Respondents with inadequate health literacy knew significantly less about their disease than those with adequate literacy. Multivariate analysis indicated that health literacy was independently related to disease knowledge. There are many opportunities to improve patients' knowledge of their chronic disease(s), and efforts need to consider their health literacy skills.

Chronic disease prevention and control activities--United States, 1989.

Although chronic diseases account for 75% of the mortality and a substantial proportion of serious disability in the United States, data regarding the activities and capacity of public health agencies to control chronic diseases are limited. To assess resources, needs, and priorities in chronic disease prevention and control during fiscal year (FY) 1989, the Association of State and Territorial Chronic Disease Program Directors (ASTCDPD), in cooperation with the Public Health Foundation, recently completed a national survey of all state and territorial health agencies. This report summarizes those findings of the survey that address resources and planning/evaluation activities.
