Changes in mammography use: economic, need, and service factors.

OBJECTIVES: The purpose of this study was to document changes in mammography use between 1987 and 1990 and assess the relationship of use to selected economic, need, and health system factors. METHODS: Independent random-digit-dialed telephone surveys of women between 52 and 75 years of age were conducted. RESULTS: Between 1987 and 1990, the proportion of women who had had a mammogram in the past year increased from 31% to 51%. Though income was significantly related to overall patterns of use, it was not associated with recent mammogram use in 1990. Women with a family history of breast cancer reported greater use at both times, as did women who reported having a regular physician (particularly a gynecologist or internist). When all other variables were controlled for, women were over nine times more likely to have had multiple and recent mammograms in 1990 than in 1987. CONCLUSIONS: Mammography use dramatically increased between 1987 and 1990. There were strong relationships between the type of regular physician and mammography screening and between economic and personal history and repeated and recent mammography use.

Work-site nutrition intervention and employees' dietary habits: the Treatwell program.

In a randomized, controlled study of the Treatwell work-site nutrition intervention program, which focused on promoting eating patterns low in fat and high in fiber, 16 work sites from Massachusetts and Rhode Island were recruited to participate and randomly assigned to either an intervention or a control condition. The intervention included direct education and environmental programming tailored to each work site; control work sites received no intervention. A cohort of workers randomly sampled from each site was surveyed both prior to and following the intervention. Dietary patterns were assessed using a semiquantitative food frequency questionnaire. Adjusting for work site, the decrease in mean dietary fat intake was 1.1% of total calories more in intervention sites than in control sites (P less than .005). Mean changes in dietary fiber intake between intervention and control sites did not differ. This study provides evidence that a work-site nutrition intervention program can effectively influence the dietary habits of workers.

Differential bone scanning.

This is a preliminary report of eleven patients with painful total joint arthroplasties. In their evaluation the difficulty in the differential diagnosis between the loose and the infected total joint becomes apparent. We have found the use of differential bone scans an accurate method to identify the infected total joint. Further study along these lines is indicated with a larger series and generalization to other types of implants.

An evaluation of cryosurgery for basal cell carcinoma.

Fifteen histologically proven basal cell carcinomas were treated by conventional cryosurgery. Three to 6 months following healing, the entire treated area was excised and serially sectioned. There was clinical and microscopic evidence of residual tumor in two of the 15 cases and microscopic evidence of recurrence in one additional patient (20 percent recurrence).

Impact of a physician intervention program to increase breast cancer screening.

In order to improve compliance with the National Cancer Institute's breast cancer screening guidelines, we developed a multifaceted intervention designed to alter physician screening practice. A pre-post test, two-community design was used. Primary care physicians in one community served as the control. Data were collected by two mailed surveys (1987 and 1990). Response rates were 61% and 64%, respectively. The physician intervention program consisted of a hospital-based continuing medical education program and an outreach component which focused on implementing a reminder system. Outcome measures were self-reported attitudinal, knowledge, and screening practices changes. In spite of an impressive change in comparison community physicians' practice, the difference in change over time in the intervention community physicians' ordering of annual mammography compared to the change in the comparison community physicians' ordering was significant (P = 0.04). The adjusted odds ratio is nearly 8. We conclude that our in-service continuing medical education program was successful in improving breast cancer screening practices among primary care physicians.
