Using indirect questions to detect intimate partner violence: the SAFE-T questionnaire.

A screening instrument for detecting intimate partner violence (IPV) was developed using indirect questions. The authors identified 5 of 18 items studied that clearly distinguished victims of IPV from a random group of health conference attendees with a sensitivity of 85% and a specificity of 87%. This 5-item instrument (SAFE-T) was then tested on 435 women presenting to three emergency departments and the results compared to a direct question regarding current abuse. The SAFE-T questions detected only 54% of the women who admitted being abused and correctly classified 81% of the women who said they were not victims. The 1-year prevalence of IPV in this sample of women presenting to an emergency department was 11.6%. The authors conclude that indirect questioning of women appears to be more effective at ruling out IPV in an emergency department population and may be less useful for women "early" in an abusive relationship.

Effect of gender, age, and relevant course work on attitudes toward empathy, patient spirituality, and physician wellness.

BACKGROUND: The emphasis in medical education on viewing the patient as a whole person addresses current concerns about the negative impact of standard physician training that may lead to impaired patient-physician relationships. PURPOSES: To assess self-ratings of empathy, spirituality, wellness, and tolerance in a sample of medical students and practitioners to explore differences by gender, age, and training. METHODS: A survey was created that assesses empathy, spirituality, wellness, and tolerance in the medical setting. Surveys were completed anonymously by medical students and practitioners from the medical school. RESULTS: The youngest groups scored highest on empathy and wellness and lowest on tolerance. Participation in medical school wellness sessions correlated with higher empathy and wellness scores; participation in both empathy and spirituality sessions correlated with higher empathy scores. CONCLUSION: Exposure to educational activities in empathy, philosophical values and meaning, and wellness during medical school may increase empathy and wellness in medical practice.

Risk-factor fusion for predicting multifactorial diseases.

A generalized classification methodology is developed to predict the presence or absence of a multifactorial disease from a set of risk factors thought to be correlated with the disease. The methodology includes fusion to combine risk factors into a single feature vector, normalization to overcome the problems associated with fusing features which have different formats and ranges, discrete Karhunen-Loeve transform (DKLT)-based transformation to facilitate parametric classifier development, the selection of features with high interclass separations, and the design of parametric classifiers. The validity of the method is demonstrated by applying it to predict the occurrence of gout from 14 risk factors. Cross-validation evaluations on 96 patients, 48 clinically diagnosed to have gout and 48 diagnosed to not have gout, showed that an average classification accuracy of 75.7% can be obtained. Even more promising is that higher classification accuracies can be achieved through the careful selection of the DKLT transformation matrix which in turn involves selecting design sets that are good representatives of the gout and nongout classes. It is concluded that the generalized methodology developed in this paper is quite effective in predicting multifactorial diseases and can, therefore, assist/support a physician in diagnosing a multifactorial disease.
