We aimed to identify the number of patient consultations in six general practices in the South-East of Amsterdam, and the incidence of HIV indicator conditions reported in their medical files prior to diagnosis. METHODS A cross-sectional search(More)

DESIGN Retrospective, cross-sectional study of electronic health records from 36 general practitioners in 2008. SETTING General practice in the Netherlands. SUBJECTS Primary care(More)
BACKGROUND Patients with atrial fibrillation (AF) are at increased risk for stroke. Antithrombotic treatment reduces this risk. Antithrombotic treatment consists of either administration of oral anticoagulants (OAC) or the provision of an antiplatelet drug. International guidelines provide advice on the preferred treatment, thereby balancing the risks and(More)
BACKGROUND Reasons for intentional non-adherence to guidelines are largely unknown. The objective of this systematic review was to gain insight into and categorize reasons for intentional non-adherence and their validity.

BACKGROUND Previous efforts such as Assessing Care of Vulnerable Elders (ACOVE) provide quality indicators for assessing the care of elderly patients, but thus far little has been done to leverage this knowledge to improve care for these patients. We describe a clinical decision support system to improve general practitioner (GP) adherence to ACOVE quality(More)

Improved education and cardiovascular health in early age have been suggested to be bringing about this effect. The aim of this study was to estimate the age-specific dementia incidence trend in primary care records from a large(More)

As a part of the Improving Care of Vulnerable Elders (ICOVE) project, interventions were designed to improve delirium screening and reduce use of strong anticholinergic medications while avoiding contributing to alert fatigue.

We tested the inter-rater reliability and validity of the Dutch version of the CORE. METHODS Thirty-seven elderly, depressed in-patients were studied. The CORE, Salpêtrière Retardation Rating Scale (SRRS), Quick Inventory of(More)
Guidelines provide recommendations for antithrombotic treatment to prevent stroke in people with atrial fibrillation, but oral anticoagulant prescriptions in Dutch primary care are often discordant with these recommendations. Suboptimal guideline features (i.e. format and content) have been suggested as a potential explanatory factor for this type of(More)
