Many medical conditions are caused or exacerbated by heavy drinking, necessitating alcohol screening and discussion in primary care practices. This is particularly true of hypertension, the most common primary diagnosis in the United States, which has been linked to the regular consumption of 3 or more standard alcoholic beverages a day. The Accelerating Alcohol Screening-Translating Research into Practice (AA-TRIP) project was designed to improve detection and management of alcohol problems in primary care patients with hypertension. Medical providers are being trained using the Practice Partner Research Network's- Translating Research into Practice (PPRNet-TRIP) quality improvement model. This includes a multi-method intervention (electronic medical records, on-site academic detailing, practice feedback reports and annual network meetings) to help practices increase adherence to clinical guidelines. Qualitative analyses of initial steps taken by nine primary care practices toward the routine implementation of alcohol screening guidelines are presented. Organizational factors and provider and patient characteristics all influenced the method and consistency of alcohol screening and intervention. Perceived time constraints, patient sensitivity to questions about alcohol, and possible stigma associated with a diagnosis of alcoholism were also relevant barriers requiring problem solving. 相似文献

INTRODUCTION: Controversy around sub-specialisation in a district general hospital (DGH) has been ongoing for years. AIM: To study the effect of colorectal sub-specialisation on general surgical cases. METHODS: A retrospective audit between October 2002 and September 2003, including all referrals to the outpatient clinics of a single consultant surgeon in a DGH. RESULTS: 1,055 patients were seen in outpatient clinics, of which 53% (563) were seen in rapid access colorectal clinics. Overall, 87% (914) of patients were diagnosed to have colorectal pathology. The majority of the colorectal cases were referred using the designated referral forms. There were 427 urgent, 162 soon and 325 routine referrals with colorectal pathology, and 35 urgent, 22 soon and 84 routine referrals with non-colorectal pathology. Median waiting times for urgent, soon and routine referrals were 12, 61 and 91 days, respectively, for patients with colorectal pathology, in comparison with 44, 75 and 397 days for non-colorectal pathology. CONCLUSION: This audit confirms that colorectal sub-specialisation has resulted in a significant delay in the management of patients with non-colorectal diseases. This has major implications within a DGH setting. 相似文献

Dopamine replacement therapy (DRT) for Parkinson's disease (PD) has recently been linked to the development of a number of nonmotor behavioral control problems. Punding, one of these nonmotor problems, is a term used to describe complex, purposeless stereotyped behaviors such as the repetitive handling or sorting of objects. A self-report questionnaire was adapted to assess punding in the context of dysfunctional hobby-related activities. We report the results of a survey of PD outpatients from a PD research clinic (n = 141) and non-PD controls (n = 103); conducted to identify clinical and psychological factors predictive of punding behaviors. The PD group reported hobbies and activities, which scored significantly higher on the Punding Scale than controls. Higher impulsivity, poorer disease-related quality of life, younger age of disease onset, and concomitant daily medication dosage from dopamine receptor agonists were independently predictive of higher Punding Scale scores in the PD group. These findings are similar to those seen in dopamine dysregulation syndrome, and provide further evidence for the role of impulsivity and age at disease onset in DRT-related nonmotor behavioral problems in PD. 相似文献
