CONTEXT: Breast cancer screening rates are lower in rural communities. Although studies have addressed barriers to mammography for rural residents, physician practice barriers have received less attention. PURPOSE: Controlled clinical trials have shown that the use of office reminder systems in primary care practices is related to increased clinical care rates. Therefore, we compared office systems use in primary care practices located in rural and urban communities and assessed the impact of these systems on rural-urban differences in mammography utilization. METHODS: We identified female Kansas Medicare beneficiaries aged 65 to 79 from Medicare claims data (N = 24,030) and determined which beneficiaries received a mammogram between April 1, 1999, and March 31, 2001. We linked beneficiaries to their primary care providers and obtained surveys from 180 primary care practices on their use of office reminder systems. FINDINGS: Mammography rates ranged from 20% to 92% (mean = 65%) among the 180 practices. Flowsheets with a mammography prompt were used by 33% of the practices, 38% utilized nonphysician staff to identify women due for mammograms, and 15% used computerized reminder systems. Urban practices used flowsheets more often than rural practices (44% versus 16%, P < 0.001). A multivariable regression model demonstrated higher mammography rates in urban practices, group practices, and practices using mammography flowsheets. CONCLUSIONS: Despite success in randomized controlled trials, reminder systems are not used often by primary care providers and are used even less often in rural compared to urban practices. Consistent implementation may be a major barrier to the successful adaptation of flowsheets by primary care offices.  相似文献

Objective: The objective of the study was to know about the use of alcohol among physicians and factors that were related to it. Methods: This was a cross sectional study conducted among the physicians in a medical school of eastern Nepal. A semi structured questionnaire was used to collect information. Results: There were 55 subjects in the study. Half of them were between 35-45 years age group and one fourth among them were female. There were more than 88% physicians consuming alcohol for more than 10 years. One third used to preferred whisky as their favorites drink. Use of alcohol among them was due to peer pressure and to become a social human being. Most of them drink alcohol occasionally with an average amount 30-60ml in a sitting and usually in the evening. Most of the time, they use alcohol either in parties or at home. Conclusion: Alcohol use in Nepal is very much prevalent. The use of alcohol is socially accepted in many communities. Uses of alcohol by physicians have direct effect on their health as well as the health of many people because they are role model for many people. They are also in direct contact with the patients. Steps to council the physicians may reduce the consumption of alcohol. Key words: Alcohol, Nepal, Physicians, Dependence, Abuse.  相似文献

Leukocyte adhesion defect I is a rare disorder (1:1,000,000) caused by diminished expression of CD‐18 β2 integrins on leukocytes leading to abnormal adhesion, migration, and chemotaxis. Clinical manifestations include delayed separation of umbilical cord, omphalitis, recurrent severe infections, impaired wound healing, persistent oral ulcers, and severe periodontitis in primary and permanent dentition. A 5‐year‐old girl, second‐born child to parents with consanguinity, presented with pain and mobility of lower teeth. There was history of recurrent infections and multiple hospital admissions with CD18 level‐3% and frame shift mutation in ITGB2, on 21q22.3. There were scars on hands and feet. Oral examination revealed multiple missing teeth and periodontitis in primary dentition. Oral prophylaxis and palliative treatments were performed with periodic follow‐ups. Interdisciplinary care is ubiquitous for patients with immune deficiencies. Early consultation with pediatric dentists and exploration of medical history is essential for diagnosis and treatment of rare diseases.  相似文献
