[Ambulatory, comprehensive, behavior therapy-oriented weight reduction program (Optifast Program). An alternative therapy in obstructive sleep apnea].

We investigated the therapeutic effect of marked body weight reduction on the predominantly obstructive sleep apnea syndrome by the application of an out-patient, behaviour therapy based body weight reduction program (Optifast-program) in five of our obese apnea patients (mean overweight by Broca 53.6 +/- 24.8 kg). Mean body weight reduction was 32.7 +/- 15.8 kg after six months. The mean apnea-index of 34.5 +/- 23.1/h prior to the weight reduction dropped to 7.8 +/- 6.1/h after therapy. The mean apnea-hypopnea-index (so called "respiratory disturbance index", RDI) could be reduced from 45,7 +/- 26.0/h to 14.0 +/- 11.4/h. The best therapeutic effect on the sleep related respiratory parameters was seen in patients who reached their normal weight whereas the absolute weight reduction itself seems to be less important. Our results should encourage this causal therapy in appropriate patients.

Sources of selection bias in evaluating social programs: an interpretation of conventional measures and evidence on the effectiveness of matching as a program evaluation method.

This paper decomposes the conventional measure of selection bias in observational studies into three components. The first two components are due to differences in the distributions of characteristics between participant and nonparticipant (comparison) group members: the first arises from differences in the supports, and the second from differences in densities over the region of common support. The third component arises from selection bias precisely defined. Using data from a recent social experiment, we find that the component due to selection bias, precisely defined, is smaller than the first two components. However, selection bias still represents a substantial fraction of the experimental impact estimate. The empirical performance of matching methods of program evaluation is also examined. We find that matching based on the propensity score eliminates some but not all of the measured selection bias, with the remaining bias still a substantial fraction of the estimated impact. We find that the support of the distribution of propensity scores for the comparison group is typically only a small portion of the support for the participant group. For values outside the common support, it is impossible to reliably estimate the effect of program participation using matching methods. If the impact of participation depends on the propensity score, as we find in our data, the failure of the common support condition severely limits matching compared with random assignment as an evaluation estimator.

Dietary effects of the National School Lunch Program and the School Breakfast Program.

In this paper we use 24-h dietary recall data to assess the dietary effects of participation in the National School Lunch Program (NSLP) and the School Breakfast Program (SBP). After adjustment for differences in characteristics between NSLP participants and nonparticipants, NSLP participation is associated with higher lunch intakes of vitamin A, calcium, and magnesium, and a lower intake of vitamin C. Although mean intakes of other key dietary components such as food energy, iron, cholesterol, and sodium are higher for NSLP participants than for nonparticipants, these differences appear to be due to underlying differences in unobserved characteristics (eg, food preferences, appetites, or food energy needs) rather than to the NSLP. Both at lunch and over 24 h, NSLP participation is associated with consumption of a higher percentage of food energy from fat and saturated fat. SBP participation is associated with higher breakfast intakes of food energy, calcium, riboflavin, phosphorus, and magnesium, and with a higher percentage of breakfast food energy from fat and saturated fat, and a lower percentage of food energy from carbohydrate.

Breast cancer screening: first round in the population-based program in Valencia, Spain. Collaborative Group of Readers of the Breast Cancer Screening Program of the Valencia Community.

PURPOSE: To analyze the results of round 1 of the population-based Valencia Breast Cancer Screening Program. MATERIALS AND METHODS: In this program, 78,224 (72.98%) of the 107,178 women invited (aged 45-65 years) underwent screening. Complementary views were obtained in 5,771 women (7.38%). Among the total population studied, 3,502 (4.48%) underwent short-term mammographic follow-up studies; 3,898 (4.98%) underwent additional studies and treatment at hospitals. Five hundred eighty-seven women (0.75%) underwent biopsy. RESULTS: Cancer was detected in 334 patients (4.27 cancers per 1,000 women [3.24 per 1,000 women aged 45-49 years, 6.30 per 1,000 women aged 60-65 years]; six patients with lobular carcinoma in situ excluded). The estimated sensitivity was 89%; specificity, 99%. The positive predictive value of mammography was 8.56%; of mammography with additional examinations, 26.82%; and of biopsy, 56.89%. Forty-one patients (12.28%) had ductal carcinoma in situ; 284 (85.03%) had infiltrating carcinoma. In 73 (25.70%) of the 284 patients, infiltrating carcinomas were smaller than 1 cm. Two hundred twenty-five patients (76.27%) had no lymph node involvement. One hundred seventy-nine (61.09%) had stage 0 or 1 cancer. CONCLUSION: Results are consistent with other published results; differences are due to methods and patient population characteristics.

Community support programs: program evaluation and public policy.

The plight of chronic psychiatric patients in the community has led to a major federal effort to resolve fragmented and disorganized care. The Community Support Programs (CSPs) recently funded by NIMH offer the promise of reducing these difficulties by creating comprehensive human service systems at the local and state levels. However, the author points out that these demonstration projects should be evaluated lest they continue to operate on the basis of rhetoric rather than fact. He presents an evaluation framework whereby indexes pertinent to each program goal of the CSPs can be measured and the resulting data used for public policy purposes.

Prognosis of patients with severe congestive heart failure referred to the cardiac transplant program. Osaka University Cardiac Transplant Program.

In any program for cardiac transplantation, appropriate recipient selection is critically important. The purpose of this study is to evaluate the prognosis of 42 patients with severe cardiac dysfunction who were referred to the Patient Referral Committee of the Osaka University Cardiac Transplant Program from August 1990 to July 1993. All of the patient profiles and clinical data were presented and discussed in the Committee Conference. The Committee classified the patients into three groups according to the following criteria: Class A; 14 patients judged to have a medical indication for heart transplantation, Class B; 7 patients with possible indications which required reevaluation for a definite indication after further intensive medical treatments, and Class C; 21 patients who did not have indications for heart transplantation or who required further clinical examinations and/or medical treatments before a final judgment. Twelve of the 14 Class A patients had a history of NYHA functional class IV and ejection fractions were 25% or less in all of the patients but one (18.5 +/- 1.7%). Six patients in Class A had a history of ventricular tachycardia. The one-year survival rate of Class A patients was 60%, and only 28% survived for 28 months. One patient underwent successful heart transplantation in the United States. If we assume that this patient would have died within a year without heart transplantation, the estimated one-year survival rate would fall to 48%, which is comparable to the survival rate of patients who have been accepted for transplant, but are being treated medically, in Western countries.(ABSTRACT TRUNCATED AT 250 WORDS)

A comparison between an outpatient hospital-based pulmonary rehabilitation program and a home-care pulmonary rehabilitation program in patients with COPD. A follow-up of 18 months.

AIM: In this study, the effects of a 12-week hospital-based outpatient pulmonary rehabilitation program (HRP) are compared with those of a 12-week home-care rehabilitation program (HCRP) in COPD patients. A control group received no rehabilitation therapy. METHODS: After randomization and stratification, effects on lung function, exercise performance (4-min walking test and cycle ergometer test), dyspnea, and leg effort during exercise, and well-being were assessed in 45 COPD patients with moderate to severe airflow limitation (mean [SD] FEV1 percent predicted, 42.8 [8.4]). RESULTS: After HRP and HCRP, at 3 to 6 months after the start of the study, equal improvements were detected in exercise capacity and in Borg dyspnea and leg effort scores at similar work levels during the cycle test. However, whereas after HRP at longer term values tended to return to baseline outcome, after HCRP a further ongoing significant improvement in exercise capacity was observed, while Borg dyspnea scores remained significantly improved over 18 months. Improvements in cycle workload and dyspnea score were significantly better maintained after HCRP as compared with HRP. Lung function, arterial oxygen saturation, and heart frequency during exercise did not change. A significant improvement in well-being was maintained over 18 months in both rehabilitation groups. CONCLUSION: Beneficial effects are achieved both after a HRP and a HCRP in COPD patients with moderate to severe airflow limitation. Yet we recommend to initiate HCRPs as improvements are maintained longer and are even further strengthened in this setting.

Voluntary programs: ADA Seal program and international implications.

For about 130 years the American Dental Association (ADA) has aided the profession and the public in selecting safe and effective dental products. Since 1930, dental products have been evaluated through the ADA Seal program. In accordance with the ADA's Bylaws, the Council on Scientific Affairs assesses information evaluating the safety, efficacy, appropriate use, and promotional claims of dental products. In doing so, the Council may award the ADA's Seal of Acceptance. In collaboration with interested parties, expert consultants, and Council members, the ADA produces guidelines suggesting appropriate methodologies and submission data to assist manufacturers in voluntarily earning the Seal of Acceptance. To date, numerous professional and consumer products have been evaluated, and about 1,300 of these products bear the Association's Seal of Acceptance. When a product is awarded the Seal it means that adequate data have been submitted and reviewed and, based on available information, the product meets ADA guidelines of safety and effectiveness. Dental health care professionals and consumers who use products that have the Seal can be confident that a product's properties and performance are consistent with current professional standards and manufacturers' claims. The ADA Seal program serves to help dentists and manufacturers meet their ethical obligations to the public by promoting safe and effective health care products.

The rural dental health program: the effect of a school-based, dental health education program on children's utilization of dental services.

Eighteen-hundred rural children ages five through thirteen were randomly assigned for dental treatment to a school-based practice, and to private practitioners in the community. Simultaneously, five of the nine public schools attended by the children offered an enriched program of dental education while the remaining schools taught the regular health education courses. All children participated in a school based fluoride program and their dental treatment was provided without charge. Data indicating how the children utilized dental services were collected over the three-year treatment phase of the study. Evidence from the third treatment year indicates that children assigned to the school based practice who also attended a school offering enriched dental health education used dental services on a more regular basis than children in the other three groups. Evidence obtained from log-linear modeling supports the hypothesis that dental health education had a positive effect on children's utilization of dental service.

Survey of cause-of-death query criteria used by state vital statistics programs in the US and the efficacy of the criteria used by the Oregon Vital Statistics Program.

A survey of the 52 vital statistics registration areas in the United States revealed that at least 23 did not fulfill the minimum cause-of-death query guidelines recommended by the National Center for Health Statistics. The Oregon Center for Health Statistics is one of only a few that query certifying physicians at a comprehensive level. During August 1986-July 1987, a total of 2,453 of 23,238 death certificates were returned to the certifiers for additional information, not including those returned in a tobacco use study. More than one-half (56.1 per cent) resulted in new and more specific underlying cause-of-death data. Only 5.2 per cent of the queries were unanswered. One probable result of Oregon's program is that the state has the highest percentage of liver cirrhosis and disease deaths attributed to alcohol abuse in the United States. Nationally, 41.7 per cent of all liver disease and cirrhosis deaths in 1984 were listed as due to alcohol compared to 82.4 per cent in Oregon. The state's total liver cirrhosis and disease death rate (12.0 per 100,000 population) is only marginally higher than the United States rate (11.6). The query program also serves to locate maternal deaths that would otherwise not be reported, as well as to provide more accurate cause-of-death statistics in general.

Pawtucket Heart Health Program point-of-purchase nutrition education program in supermarkets.

Point-of-purchase nutrition education in supermarkets is one intervention strategy of the Pawtucket Heart Health Program, a community cardiovascular disease prevention program in Pawtucket, Rhode Island. Using consumer intercept interviews, awareness of shelf labels and their effect on purchase behavior have been continuously evaluated. Between 1984 and 1988, the percent of shoppers who could identify correct labels increased from 11 percent to 24 percent (95% confidence intervals of difference: 7.17). The percent who reported they were encouraged to purchase the identified foods increased from 36 percent to 54 percent (95% CI of difference: 5.41).

Relationship of nursing program predictors and success on the NCLEX-RN examination for licensure in a selected associate degree program.

This ex post facto correlational study sought to determine the relationship of selected admission criteria and performance in the integrated nursing major didactic courses of an associate science in nursing degree program as predictors for performance on the licensing examination for registered nurses. A significant positive relationship at .01 with NCLEX was individually demonstrated with all of the seven ASN nursing courses and with SAT verbal scores. Not significant were age at graduation from the program, high school class rank percentile, and SAT math scores. Multivariate regression weights derived from an equation using course grades of 104 graduates were used to predict NCLEX scores. The predicted scores correlated strongly (n = .78551, p less than .001) with the actual scores. Ten predicted and actual scores were provided for demonstration.

[A pathogenic manpower program: the program for foreign domestics].

Every year, a special federal program arranges for the arrival of about 12,000 educated women to Canada to work several years in private homes as housekeepers. However, in order to meet the needs of the employer and the Canadian economy, these women are denied their fundamental freedoms and are deliberately kept in a precarious situation material and psychologically and with respect to their status. Because it exposes these female workers to such factors of instability and to the negative effects of key experiences, this program carries the seed of mental illness.

Prepayment with office-based physicians in publicly funded programs: results from the Children's Medicaid Program.

This paper is a report of the results of a demonstration designed to provide empirical evidence regarding the effects of alternative approaches to paying physicians for serving children in the Medicaid program: (1) visit fees set at twice regular Medicaid fees in return for physician agreement to manage utilization and (2) capitation and financial risk-sharing along with the same physician agreement to manage utilization. Participating physicians were assigned randomly to either of the two payment groups. Comparisons of utilization and expenditures were made between these two plans and the regular Medicaid program (fee-for-service, low fees). Results showed no adverse effect of capitation payments on primary care visits to office-based physicians. Capitation physician referrals to specialists decreased relative to all other groups studied, consistent with the theory that the financial incentives in capitation will lead primary care physicians to reduce referrals to specialists.

[Results of a multiphase oncology population screening program in the community of Becej 1986-1987. I. The Hemoccult Program].

In the framework of a multiphase oncologic population screening-program performed in persons above 40 years of age according to the census in the community of Becej during 1986-1987, Hemoccult screening program, together with the fluorographic action involved 16.895 (83.80%) persons out of 20.160 predicted ones which was far less than the involvement of persons through the distribution and gathering of the screening material by a specialized nurse. In 907 (5.37%) Hemoccult positive persons out of which 121 (13.34%) persons rejected to cooperate or did not respond to the invitation for further investigation 16 malignant neoplasms in the lower part of the colon (anus 1, rectum 11, sigma 4) were detected as well as 53 polyposes of the rectum and the anus. Besides, 4 malignant neoplasms of the skin were found and 29 benign tumours (27 adenomas of the prostate gland, 1 fibrolipoma glutei and 1 cysta renis). Apart from these diseases 569 other previously not treated pathologic states were found, i.e. new pathologic states were detected in 85.37% of Hemoccult-positive persons. Previously known pathologic states were confirmed in 22.52% of Hemoccult-positive persons. Diagnostic was performed by the rigid rectoscope and in Hemoccult-positive persons with the negative rectoscopis finding radiologic and fiberoscopic investigations were carried out in the less scope due to the deficiency of financial resources. The number of detected malignant neoplasms of the colon surpassed the three-fold value of the average Vojvodina incidence of these localizations of malignant neoplasms at this age.(ABSTRACT TRUNCATED AT 250 WORDS)
