RESUMO
OBJECTIVE: To determine what proportion of patients with dementia seen by family physicians are assessed and managed according to the recommendations of the Canadian Consensus Conference on Dementia (CCCD). DESIGN: Retrospective medical record review. SETTING: Outpatient services in university-affiliated family practice clinics in Calgary, Alta; Ottawa, Ont; and Toronto, Ont. PARTICIPANTS: One hundred sixty patients who were diagnosed with dementia between January 1, 2000, and June 1, 2004. MAIN OUTCOME MEASURES: Use of the Mini-Mental State Examination (MMSE); collateral history; physical examination maneuvers; initial laboratory tests; diagnostic imaging; caregiver identification, assessment, and referral; driving assessment; specialist referral patterns; and other recommendations of the CCCD. RESULTS: The average age of patients assessed was 83 years; most patients (66.3%) were female. More than half (54.1%) were diagnosed with Alzheimer disease or vascular dementia. More than 25% of patients were not given a specific diagnosis: 13.1% were labeled as "dementia," and 12.5% as "not yet diagnosed." For most patients (69.6%) a collateral history was obtained and a primary caregiver identified (79.4%). Few physicians, however, assessed caregiver stress (33.1%) or referred caregivers for support (12.5%). Most patients (80.6%) seen by their family physicians for cognitive changes underwent at least one MMSE. The average score on the first MMSE was 23.5 (of 30) points. Most physicians ordered appropriate "basic" blood tests as part of their assessment. Forty percent of patients had computed tomographic examinations within 3 months of reporting symptoms of cognitive difficulties to their family physicians. Of these, 25% met the criteria for computed tomographic scan as recommended by the guidelines. Only 36.5% were asked about driving status or safety concerns and had this inquiry documented. Of those, 15.5% were referred for driving evaluations and 12.5% were reported to the Ministry of Transportation. CONCLUSION: There is fair to good compliance with recommendations of the 1999 CCCD guidelines. There is, however, little assessment of caregiver coping and referral of caregivers for support. Similarly, there is little assessment of driver safety and referral for formal driving evaluations. Computed tomographic imaging as part of the evaluation of dementia is overused.
