Communicating results of diagnostic mammography: what do patients think?

RATIONALE AND OBJECTIVES: The purpose of this study was to investigate women's preferences for who (radiologist or referring physician) should communicate the results of diagnostic mammography. MATERIALS AND METHODS: Data from 153 women presenting to two sites for diagnostic mammography between February and June 1995 were collected with a 24-item, self-administered, closed-ended survey. For both normal and abnormal hypothetical results, contingency tables with chi2 tests and multiple logistic regression were used to determine the association, if any, between women's characteristics and their preferences. RESULTS: Women undergoing diagnostic mammography preferred that their radiologists disclose their normal (90%) and abnormal (88%) mammogram results to them immediately after their examination, rather than have their referring physicians disclose results at a later time. In the case of normal findings, women whose regular physicians were specialists were less likely to want to hear first from their radiologists (odds ratio [OR] = 0.06; 95% confidence interval [CI] = 0.01, 0.77; P = .03), but women who were nervous about learning their results were more likely to want to hear first from their radiologists (OR = 4.5; 95% CI = 1.2, 17.3; P = .03). CONCLUSION: Radiologists may want to consider assessing women's preferences for who communicates their mammogram results, as most women in this study preferred to hear these results from their radiologists rather than waiting to hear from their referring physicians.

Cleaning and disinfectant properties of dental surface disinfectants.

The appropriate use of disinfectants for operatory surfaces constitutes a major component of a routine infection control protocol. Both the cleaning and the disinfection abilities of the various available products are important to consider when selecting a surface disinfectant. This study shows the importance of initial surface cleaning as a mandatory first step in surface asepsis. All manufacturers emphasize this in their written directions by stating that the products should be used on precleaned surfaces. Based on the inability to remove dried organic material and a lack of effective antimicrobial activity in the presence of accumulated bioburden, preparations containing high concentrations of alcohols (greater than or equal to 70%) should not be used as the sole agent for routine precleaning and disinfection. Properly diluted iodophor, sodium hypochlorite, and complex phenol preparations are superior in comparison with other disinfectants in accomplishing the initial precleaning of surfaces.
