Advance directive completion rates remain poor in the ambulatory setting. The purpose of this study was to explore and contrast staff provider and resident physicians’ experiences with advance care planning (ACP) and to identify barriers to this process in the primary care setting. A 17-item survey was administered to staff primary care providers and categorical internal medicine residents. Staff providers were more likely to discuss ACP after prompting from patients’ family members (P < .02) or after a change in health status (P < .02) and were more likely to believe that non-physician members of the care team should counsel patients about ACP. The majority of respondents cited system-based barriers as major obstacles to ACP. Strategies aimed at systematizing the ACP process for both patients and providers are needed.

We conducted a retrospective study of symptom assessment calls for adult patients at a US call centre, Ask Mayo Clinic. A total of 27,979 symptom assessment calls were received from July 2006 to June 2007. Calls concerning female patients predominated in all age groups and accounted for 71% of calls, but decreased significantly with increasing age. The average duration of an adult call was 10 min, and the duration increased with increasing age of the adult patient. The greatest frequency (8%) of calls were related to symptoms of abdominal pain, followed in frequency by skin problems (6%), pregnancy-related issues (6%), cold symptoms (4%), and chest pain or chest discomfort (4%). Surrogate calls accounted for 14% of adult calls but the proportion was significantly higher (40%) if the patient's age was 80 years or greater. Call centres should recognize the sex- and age-related trends in calls and adjust the training of their registered nurses accordingly.

Background and Purpose: Stroke is a well-known risk factor for vascular dementia. However, the association of transient ischemic attacks with cognitive impairment is less well-established. Methods: Records from Third National Health and Nutrition Examination Survey were abstracted for demographic and medical information for participants with an age !60 years who reported being free of stroke. Five self-reported symptoms (weakness, numbness, loss of vision, inability to speak, and severe dizziness) were used as surrogates representing transient ischemic attacks. Information on conventional risk factors for vascular dementia was also obtained. Multivariable logistic regression was used to examine risk factors for memory impairment. Results: 4617 participants were included with a sample-weighted prevalence of memory impairment of 6.6% (1417 participants). The final multivariable analysis revealed a significant association between transient weakness and memory impairment (odds ratio 1.52, 95% CI 1.11-2.07). The other 4 transient ischemic attacks symptoms were not significantly associated with memory impairment in the final model. Systolic blood pressure >140 was most strongly associated with prevalent memory impairment (odds ratio, 9.78, 95% CI 1.49-64.3). Other associated risk factors included non-white race, male gender, age, education ≤12 years, and history of any alcohol use. Conclusion: Among transient ischemic attacks symptoms, self-reported weakness in the face, arm, or leg was significantly associated with memory impairment. This study indicates that transient ischemic attacks symptoms are, even in the absence of stroke, associated with memory impairment. Aggressive risk factor modification in patients with TIA symptoms may be warranted to prevent potential future memory loss.
