Total parathyroidectomy and autotransplantation.

Total parathyroidectomy and autotransplantation of tissue to the forearm was practiced in 50 chronic renal failure patients as treatment for secondary hyperparathyroidism. Four hyperplastic glands were removed in all cases. Followup observation ranged from 3 to 42 months. Serum parathyroid hormone, alkaline phosphatase, calcium and phosphorus levels decreased significantly following the procedure (P less than 0.005) and remained stable during the period of observation. Significant bone pain present in 26 patients improved or ceased in 19; pruritus, present in 39 patients, universally improved. Strong radiographic suggestion of secondary hyperparathyroidism, present in 38 patients, improved or disappeared in 17. Three patients remained functionally hyperparathyroid, requiring further tissue removal. Autograft function 3 to 7 days after transplantation was demonstrated in 3 cases by differential parathyroid hormone concentration determinations. Essentially all patients experienced symptomatic improvement after surgery and most showed objective evidence of improved calcium-phosphorus metabolism and bone healing.

Dietary intakes of preschool children in LA Pa, El Salvador, Central America.

A dietary survey was conducted in a department of El Salvador as part of an assessment of the nutritional status of preschool children. Intake of calories, protein and retinol equivalents were estimated using a 24-hour recall technique. The average daily energy intake for children 1-4 years old was 866 Kcal representing 60% of the 1973 level recommended by the Institute of Nutrition of Central America and Panama (INCAP), for this age group, and 76% of the recommended level on a body-weight basis. Average protein intake per child per day in the same age group was 31.3 g, which represents 110% of the recommended level for the age group, and 136% of the recommended level on a body weight basis. The estimated retinol equivalent intake was 36% of the recommended allowance. In general, the results of the present study were similar to those obtained in the study carried out in El Salvador by INCAP during the period September-November, 1965.

Physician and patient predictors of health maintenance visits.

BACKGROUND: Because of a strong association between health maintenance visits (HMVs) and cancer screening, knowledge of the predictors of an HMV have implications for screening. OBJECTIVE: To examine the association of an HMV with patient, physician, and practice characteristics in the primary care setting. DESIGN: A statewide study of cancer screening was conducted in Colorado to determine concordance with the National Cancer Institute's guidelines for screening for breast, cervical, prostate, and skin cancer. Medical records form patients were randomly chosen from primary care practices. Predictors of an HMV were determined by fitting a logistic model to baseline data, adjusting for the cluster sampling of patients within practices. SETTING: Nonacademic primary care practices in Colorado. PARTICIPANTS: A total of 5746 patients aged 42 to 74 years from 132 primary care practices. MAIN OUTCOME MEASURE: Whether a patient had an HMV in the previous year. RESULTS: Of all patients, 31% had an HMV in the previous year. Patient characteristics associated with having HMVs included nonsmoking status, odds ratio (OR) (95% confidence interval [CI]) of 1.27 (1.11-1.46), age, and sex. Women aged 50 to 69 years were significantly more likely to have an HMV than men aged 50 to 69 years (OR, 1.30; 95% CI, 1.10-1.54). Among adults aged 70 years and older, there were no significant sex differences in receiving HMVs. Physician and practice characteristics associated with providing HMVs included practice size (> or = 3 full-time physicians) (OR, 1.34; 95% CI, 1.01-1.77), physician contemplation of changing approaches to cancer screening (OR, 1.33; 95% CI, 1.04-1.70), and physician female sex (OR, 1.33; 95% CI, 1.04-1.70). Physician age and specialty (general internist or family physician) were not associated with the level of health maintenance delivery. CONCLUSION: Certain subgroups, such as smokers, patients in smaller practices, and physicians not yet considering changing their approach to cancer screening, could be targeted in future intervention studies designed to provide preventive services in primary care settings.

A feasibility test of a brief educational intervention to increase fruit and vegetable consumption among callers to the Cancer Information Service.

BACKGROUND: In this paper, results are reported from a pilot study designed to test the feasibility of a proactive educational intervention delivered to callers of the Cancer Information Service (CIS). METHODS: The study used a randomized two-group design (intervention vs control). Callers assigned to the intervention condition received a brief educational intervention at the end of usual service to increase fruit and vegetable consumption. As part of the intervention, key education messages and materials drawn from the 5 A Day for Better Health program of the National Cancer Institute were provided to CIS callers over the telephone and then reinforced with two follow-up mailings. RESULTS: Results from this pilot study indicated high levels of adherence to protocol by CIS Information Specialists who delivered the intervention to eligible CIS callers. Results obtained from the 4-week telephone follow-up interviews indicated that intervention subjects (n = 142) reported higher consumption of fruits and vegetables, averaging approximately 0.75 servings more per day (P < 0.01) than control subjects (n = 134). CONCLUSION: Nearly 80% of CIS callers endorsed the strategy of providing 5 A Day information at the end of usual service, even if such information was not specifically requested by the caller (i.e., the information was provided to CIS callers proactively.

Effectiveness of a telephone outcall intervention to promote screening mammography among low-income women.

BACKGROUND: This study evaluated the impact of a telephone outcall intervention (based on the Transtheoretical Model) on screening mammography behavior among lower income, older women. METHODS: A geodemographic database, INFORUM, was used to identify low-income and minority neighborhoods throughout the state of Colorado. Residences were assigned randomly to three study groups: (1) control, (2) outcall only, and (3) advance "invitation" + outcall. Information Specialists of the Cancer Information Service implemented the protocol. Mammography adherence was assessed in telephone interviews conducted 6 months and 2 years after the initial call. RESULTS: Neither intervention had a significant effect on the main outcome, receipt of mammography in the 6-month follow-up period. At 6 months, intentions to have a mammogram were significantly stronger in the intervention groups compared with the control group, particularly among those who were precontemplators at baseline. The 2-year follow-up indicated a small increase in mammography adherence attributable to the advance invitation + outcall, but this effect was restricted to those adherent at baseline. Mammography behavior during the 6-month follow-up period was predicted strongly by decisional balance, intentions, receipt of a physical and clinical breast exam, and previous mammography behavior. CONCLUSIONS: The intervention promoted minimal movement in the stages of change for mammography. Outcall interventions may have promise for encouraging repeat mammography behavior, but more intensive interventions are likely to be necessary to promote behavior change among nonadherent women.

Increasing fruit and vegetable consumption among callers to the CIS: results from a randomized trial.

BACKGROUND: Results are reported from a large randomized trial designed to increase fruit and vegetable consumption among callers to the Cancer Information Service (CIS). METHODS: CIS callers assigned to the intervention group received a brief proactive educational intervention over the telephone at the end of usual service, with two follow-up mailouts. Key educational messages and print material derived from the NCI 5 A Day for Better Health program were provided to intervention subjects. Subjects were interviewed by telephone at both 4-week (n = 1,672) and 4-month (n = 1,286) follow-up. RESULTS: A single-item measure of fruit and vegetable consumption revealed a significant intervention effect of approximately 0.65 servings per day at 4-week follow-up (P < 0.001) and 0.41 servings per day at 4-month follow-up (P < 0.001). Using a seven-item food frequency measure that was also included in the 4-month interviews, a similar intervention effect of 0.34 servings per day was obtained (P = 0.006). The vast majority of CIS callers (88%) endorsed the strategy of providing 5 A Day information proactively. CONCLUSIONS: A brief educational intervention delivered to CIS callers at the end of usual service was associated with an increase in self-reported fruit and vegetable intake.

Lessons learned from the national heart failure project: a center for medicare and medicaid services initiative to improve the care of medicare beneficiaries with heart failure.

This column is the seventh in a series reporting on the efforts of the Center for Medicare and Medicaid Services (CMS), formerly known as the Health Care Financing Administration, to improve care for Medicare beneficiaries with heart failure. In previous columns we have described the overall structure of Medicare quality improvement efforts, detailed the structure of the national inpatient fee-for-service program known as the National Heart Failure project, and discussed the baseline quality indicator rates for the project, which are focused on rates of ejection fraction documentation and angiotensin-converting enzyme inhibitor prescription. In more recent columns, we reported on quality improvement projects from several participating hospitals, and on a pilot project exploring quality improvement efforts for heart failure based in physicians' offices. This column will focus on ways in which systematic examination of data, such as those from the National Heart Failure project, might shape future quality improvement and research efforts. The National Heart Failure project's quality indicator data are collected primarily to guide and evaluate the efforts of the CMS contractor peer-review organizations to facilitate quality improvement efforts in hospitals throughout the United States.

Baseline quality indicator rates from the National Heart Failure Project: a HCFA initiative to improve the care of medicare beneficiaries with heart failure.

This column is the third in a series reporting on Health Care Financing Administration (HCFA) initiatives to improve care for Medicare beneficiaries with heart failure. The first paper outlined the history of HCFA quality improvement projects and current initiatives to improve care in six priority areas: heart failure, acute myocardial infarction, stroke, pneumonia, diabetes, and breast cancer. The second reported in more detail the structure of the national inpatient fee-for-service heart failure initiative, known as the National Heart Failure project. It described the development of the quality indicators, the sampling strategy for selecting charts to be reviewed, and the types of local efforts spurred by the project through the activities of each state's HCFA contractor peer review organization. This article discusses baseline quality indicator rates from the National Heart Failure project. (c)2001 by CHF, Inc.
