Dementia in primary care: the first survey of Irish general practitioners.

OBJECTIVE: To investigate General Practitioners' (GPs) attitudes and practices in relation to screening, diagnosing, and disclosing a dementia diagnosis to patients. DESIGN: National postal survey. PARTICIPANTS: A random sample of 600 GPs from a national database of 2,400. RESULTS: Of the 600 GPs surveyed, 60% returned questionnaires of which 50% (300) were useable. GPs reported diagnosing on average four new cases of dementia annually. A multivariate analysis revealed that females diagnosed significantly fewer cases annually (t=5.532, df=289, p<0.001). A large majority of GPs reported performing thyroid function tests (77%), B(12) (75%) and Folic acid tests (75%) to out rule reversible causes of cognitive impairment. The most reliable signs and symptoms of dementia identified were memory problems (58%). Main barriers to diagnosis were difficulty differentiating normal ageing from symptoms of dementia (31%), lack of confidence (30%) and the impact of the diagnosis on the patient (28%). GPs' age (chi(2)=14.592, df=3, p<0.005) and gender (chi(2)=11.436, df=3, p<0.01) were significantly associated with barriers to diagnosis. Only 19% claimed they often or always disclosed a diagnosis to a patient. Over one-third of GPs (38%) reported that the key factor influencing their disclosure patterns was their perceptions of the patient's level of comprehension. Most GPs (90%) had never undergone any dementia specific training and most (83%) expressed a desire for this. CONCLUSIONS: GPs experience difficulty diagnosing and disclosing a diagnosis of dementia to patients. To improve dementia care in Ireland, there is an urgent need to develop an active and more systematic approach to GP training in dementia care.

Co-morbid and socio-demographic factors associated with cognitive performance in an elderly community dwelling Irish population.

BACKGROUND: Epidemiological studies suggest an association between health factors and dementia. The impact of these factors on the cognitive performance of the elderly population is unclear. Possible correlates of poor cognitive performance in a community dwelling elderly Irish population were examined. METHODS: Subjects were from a sample of individuals over 65 years agreeable to interview using the Geriatric Mental State (GMS)-Automated Geriatric Examination for Computed Assisted Taxonomy (AGECAT) package conducted at the subject's home. Associations between patient profiles and Mini Mental State Examination (MMSE) score were investigated in a multivariate model. RESULTS: There were 793 subjects, 528 (66.6%) female with mean (s.d.) age 74.8 (6.7) yrs. Mean MMSE score was 26.5 (3.3). 169 (21.3%) were current smokers, 198 (25%) ex-smokers. Two hundred and twenty-four (28.3%) had a history of hypertension, 85 (10.7%) case level anxiety or depression, 51 (6.4%) stroke, ten0 (1.3%) epilepsy, nine (1.1%) Parkinson's disease and 29 (3.7%) dementia. Two hundred and fifty-five (32.2%) subjects were on psychotropic medications. Factors associated with MMSE score included age (p < or = 0.0001), diagnosis of dementia (p < or = 0.0001), socioeconomic group (p < or = 0.0001), education (p < or = 0.0001), previous stroke (p = 0.0013) and use of psychotropic medication (p = 0.03). Case level anxiety or depression (p = 0.99), Parkinson's disease (p = 0.52), epilepsy (p = 0.26), smoking status (p = 0.99) and hypertension (p = 0.34) were not found to be associated with cognitive performance. CONCLUSION: Factors associated with cognitive performance included age, socioeconomic group, education, previous stroke and use of psychotropic medication. These factors should be adjusted for in studies assessing cognition in this population. Stroke prevention strategies and avoidance of psychotropic medication may benefit cognitive performance.

A systematic review of the utility of self-report alcohol screening instruments in the elderly.

BACKGROUND: Effective screening instruments are needed for the detection of alcohol use disorders (AUDs) in the elderly, in view of the significant physical, psychological and social problems associated with this phenomenon. METHODS: This paper provides details on the different self-report alcohol screening instruments that have been studied in the elderly, describing both the instruments themselves and their effectiveness as screening instruments for AUDs in different elderly populations. RESULTS: The vast majority of studies reviewed were carried out in the US, and a high proportion of these were carried out in Veterans Administrations institutions, thus limiting the generalizability of results. The CAGE was the most widely studied screening instrument, followed by the MAST or variations of the MAST, the AUDIT and variations of the AUDIT, and other screening instruments. Sensitivity and specificity of these instruments varied widely, depending on the prevalence of AUDs in the population being studied, the clinical characteristics of the population and the type of AUD being detected. The CAGE performed poorly in psychiatric populations but a newer instrument, the AUDIT-5, has had promising results to date. No studies focussed on elderly people with cognitive impairment, and there is a need for research in this area. CONCLUSIONS: Ease of use, patient acceptability, sensitivity and specificity must all be considered when selecting a self-report alcohol screening instrument for use in the elderly. Furthermore, the prevalence of AUDs in the population and the clinical characteristics of that population must also be taken into account.
