Background Primary care services are often the main healthcare service for people with dementia; as such, good-quality care at this level is important. Aim To measure the quality of care provided to people with dementia in general practice using routinely collected data, and to explore associated patient and practice factors. Design and setting Observational, cross-sectional review of medical records from general practices ( n = 52) in five primary care trusts. Method A total of 994 people with dementia were identified from dementia registers. An unweighted quality-of-care score was constructed using information collected in the annual dementia review, together with pharmacological management of cognitive and non-cognitive symptoms. Multilevel modelling was carried out to identify factors associated with quality-of-care scores. Results In total, 599 out of 745 (80%) patients with dementia had received an annual dementia review; however, a social care review or discussion with carers was evident in just 305 (51%) and 367 (61%) of those 599 cases, respectively. Despite high prevalence of vascular disease, over a quarter ( n = 259, 26%) of all patients with dementia were prescribed antipsychotics; only 57% ( n = 148) of these had undergone medication review in the previous 6 months. Those with vascular dementia who were registered with single-handed practices received poorer quality of care than those registered with practices that had more than one GP. Conclusion Although the number of people with dementia with a record of an annual dementia review is high, the quality of these reviews is suboptimal. The quality score developed in this study could be used as one source of data to identify weaknesses in practice activity that need to be corrected, and so would be of value to commissioners and regulators, as well as practices themselves.

Background Vascular diseases contribute to the causation and progression of clinical dementia. Aim To evaluate the quality of medical care for vascular diseases provided to people with dementia, the patient and practice characteristics that influence quality, and to compare care with that provided to those without dementia. Design and setting Observational, cross-sectional review of primary care records of people with dementia from 52 general practices from five primary care trusts in the UK, and comparison with publicly available summary data on patients without dementia. Method A total of 700 patients with ≥1 diagnosed vascular disease or risk factor were identified from dementia registers. Quality of care was measured on 30 indicators from the UK Quality and Outcomes Framework (QOF) for hypertension, coronary heart disease, stroke, diabetes mellitus, atrial fibrillation, heart failure, and smoking. Overall quality of vascular care was calculated for each patient with dementia. Result Level of care received by people with dementia was significantly lower compared with those without dementia for 22 of 30 (73%) indicators; most notably for measurement processes such as peripheral pulses check and neuropathy testing for diabetes, and cholesterol measures for stroke. Among people with dementia, women, those in care homes, and those with fewer comorbid physical conditions and medications were associated with lower scores for overall quality of vascular care. Conclusion The quality of medical care provided to people with dementia with regard to vascular diseases is not concordant with quality, as defined by the QOF. Research is needed to improve access to high-quality care.

Background This study explored the association between three measures of working memory ability and genetic variation in a range of catecholamine genes in a sample of children with ADHD. Methods One hundred and eighteen children with ADHD performed three working memory measures taken from the CANTAB battery (Spatial Span, Delayed-match-to-sample, and Spatial Working Memory). Associations between performance on working memory measures and allelic variation in catecholamine genes (including those for the noradrenaline transporter [NET1], the dopamine D4 and D2 receptor genes [DRD4; DRD2], the gene encoding dopamine beta hydroxylase [DBH] and catechol-O-methyl transferase [COMT]) were investigated using regression models that controlled for age, IQ, gender and medication status on the day of test. Results Significant associations were found between performance on the delayed-match-to-sample task and COMT genotype. More specifically, val/val homozygotes produced significantly more errors than did children who carried a least one met allele. There were no further associations between allelic variants and performance across the other working memory tasks. Conclusions The working memory measures employed in the present study differed in the degree to which accurate task performance depended upon either the dynamic updating and/or manipulation of items in working memory, as in the spatial span and spatial working memory tasks, or upon the stable maintenance of representations, as in the delay-match–to-sample task. The results are interpreted as evidence of a relationship between tonic dopamine levels associated with the met COMT allele and the maintenance of stable working memory representations required to perform the delayed-match-to-sample-task.
