ABSTRACT
BACKGROUND: The multiple competing demands of the busy office visit have been shown to interfere with delivery of preventive services. In this study we used physician recommendations for screening mammography to examine the relative importance of physician, patient, and visit characteristics in determining on which patient visits this preventive service will be provided. METHODS: Physicians in the Ambulatory Sentinel Practice Network (ASPN) completed a questionnaire describing their knowledge, attitudes, and beliefs about screening mammography. They also described the content of a series of nonacute care visits with women aged 40 to 75 years with regard to making a recommendation when the patient was due for screening mammography. The data were linked, and univariate and multivariate logistic regression methods were used to examine the relative importance of physician, patient, and visit characteristics on making a recommendation for mammography. RESULTS: Ninety-three physicians reported making a recommendation for screening mammography on 53.1% of nonacute visits. When modeling physician, patient, and visit characteristics separately, 70% of the variability in the model is explained by physician characteristics only, 63% by patient characteristics only, and 73% by visit characteristics only. A combined model using all characteristics explained 85% of the variability. CONCLUSIONS: Although characteristics of physicians and patients can predict frequency of recommendations for mammography, the specific characteristics of the visit are equally important. Efforts to improve delivery of preventive services in primary care that emphasize physician education and performance feedback are unlikely to increase rates of mammography recommendation. Effective strategies must consider the multiple competing demands faced by patients and physicians during each office visit and seek ways for assisting them in setting rational priorities for services.

The goal of this study was to test the hypothesis that increased consumption of vegetables and fruit would reduce markers of oxidative cellular damage that can be assessed in blood or urine. Twenty-eight women participated in a 14 day dietary intervention. The primary end-points assessed were: 8-hydroxydeoxyguanosine (8-OHdG) in DNA isolated from peripheral lymphocytes, determined by HPLC with electrochemical detection; 8-OHdG excreted in urine, measured by ELISA; malondialdehyde (MDA) in urine, measured by fluorimetric detection following derivatization with thiobarituric acid and separation via HPLC; urinary 8-isoprostane F-2alpha (8-EPG) detected by ELISA. Pre- and post-intervention plasma levels of selected carotenoids were determined by HPLC. Subjects were free living and consumed a completely defined recipe-based diet that increased their average daily consumption of vegetables and fruit from 5.8 servings at baseline to 12.0 servings throughout the intervention. Overall, the level of 8-OHdG in DNA isolated from lymphocytes and in urine and the level of 8-EPG in urine were reduced by the intervention, whereas urine concentrations of MDA were minimally affected. The reduction in lymphocyte 8-OHdG was greater in magnitude (32 versus 5%) in individuals with lower average pre-intervention levels of plasma alpha-carotene (56 ng/ml) than in individuals with higher average pre-intervention plasma levels of alpha-carotene (148 ng/ml). The results of this study indicate that consumption of a diet that significantly increased vegetable and fruit intake from a diverse number of botanical families resulted in significant reductions in markers of oxidative cellular damage to DNA and lipids.

OBJECTIVE: To describe and inform pharmacists of a rarely reported occurrence of facial palsy in an elderly patient with uncontrolled hypertension resulting from nonadherence to blood pressure medications. CASE SUMMARY: A 62-year-old Hispanic woman presented to the hypertension clinic with left facial weakness, mild eyelid lag, and auricular pain for two days. The patient self-discontinued fosinopril and minoxidil six days and two days prior to developing these symptoms, respectively. A diagnosis of idiopathic peripheral VII cranial nerve lesion was made after ruling out other possible causes. Corticosteroids were not initiated because of this patient's labile hypertension. Palliative therapy was initiated and the left facial paralysis continuously improved during the six months after discharge. DISCUSSION: Patients have rarely presented with facial paralysis as the initial feature of severe hypertension. The relationship between facial paralysis and hypertension has been reported in a small number of cases, including several reports of recurrence of paralysis during acute exacerbations of hypertension. A variety of physiologic theories to explain the relationship between facial paralysis and hypertension have been published, including small hemorrhages into the facial canal which have been confirmed by two autopsies. However, the true etiology remains unknown. CONCLUSIONS: The possible relationship between facial paralysis and uncontrolled hypertension has not been reported in pharmacy literature and has been reported only twice in subspecialty medical journals since 1990. Pharmacists should be aware of the complications of hypertension and should question patients about signs and symptoms at each visit. While Bell's palsy complicating hypertension does not appear to be a serious complication, pharmacists must appreciate that the patient should be immediately evaluated to rule out a more serious neurologic event.

The most common breast complaints are nipple discharge, breast pain and a breast mass. These problems can be evaluated in a step-wise manner to determine whether the etiology is cancer. A breast mass is the most common symptom of cancer, but breast pain and nipple discharge also must be evaluated carefully. The history and physical examination, needle aspiration, mammography, ultrasound examination and biopsy are useful in determining the underlying cause of the problem.

BACKGROUND: Breast cancer is the second most common cause of cancer death in women, with mammographic screening the only modality shown to decrease the death rate. However, only 17% to 41% of women have ever been screened, and multiple barriers to screening have been identified. This study examined physician and patient factors at a single encounter to explore components influencing mammography ordering. METHODS: Ten family physicians in a primary care research network completed daily data cards on encounters with women presenting for annual examinations, chronic problems, or breast-related complaints. Information collected included patient age, personal or family history of breast cancer, physician's perception of expected compliance, previous mammogram results, breast examination, physician's perception of need for a mammogram, whether the mammogram was ordered, and the patient's method of payment for the test. RESULTS: Eight hundred thirty-nine patients were entered into the study, and 277 mammograms were ordered. Mammograms were ordered for a greater percentage of patients with insurance (36%) than for those without insurance (26%) (P < .001). A multivariate analysis indicated that several factors helped to correctly classify 90% of mammogram ordering: the patient was making a first visit, a breast-related visit, or a visit for an annual examination; the patient had had a previous mammogram; had a breast examination at the current visit or within the past year; and the physician believed the patient would comply and believed that a mammogram was indicated. CONCLUSIONS: Factors unique to a physician-patient visit influence the physician with regard to ordering a mammogram, including the type of visit, whether the physician believes a mammogram is indicated, and the cost.

BACKGROUND: Because an estimated 70 percent of all medical care expenditures are generated by physicians, evaluation of specialty practice styles is essential to learn what changes in policies governing physician training, service delivery, and patterns of medical practice would promote cost containment. METHODS: We examined the 1981 and 1985 National Ambulatory Medical Care Survey for seven primary care diagnoses to compare practice style differences between family physicians and internists and to look for changes in family physicians' practice styles between 1981 and 1985. RESULTS: Family physicians referred fewer patients in 1985 and spent 3 to 10.5 minutes less per patient encounter than internists. Clinical laboratory testing, electrocardiogram (ECG) ordering, and radiographic examinations differed significantly between the two groups in 1981 and 1985 for some diagnoses. In 1981, family physicians did Papanicolaou smears 2.2 times more often than internists during general medical examinations; however, in 1985, there was no difference. Between 1981 and 1985, family physicians ordered significantly more laboratory tests and ECGs for some diagnoses but had no change in the number of radiographs ordered or referrals. For six diagnoses, they spent more time with a patient encounter in 1985 than in 1981. CONCLUSIONS: Family physicians and internists appear to be more alike in practice style, but significant differences remain. These differences, as well as changing practice styles of family physicians, have implications for training and health care resource distribution.
