BACKGROUND UK general practice is computerised, and quality targets based on computer data provide a further incentive to improve data quality. A National Programme for Information Technology is standardising the technical infrastructure and removing some of the barriers to data aggregation. Routinely collected data is an underused resource, yet little has(More)
BACKGROUND Chronic kidney disease (CKD) is an important predictor of end-stage renal disease, as well as a marker of increased mortality. The New Opportunities for Early Renal Intervention by Computerised Assessment (NEOERICA) project aimed to assess whether people with undiagnosed CKD who might benefit from early intervention could be identified from GP(More)
BACKGROUND The National Institute for Health and Care Excellence (NICE) recommends postpartum and annual monitoring for diabetes for females who have had a diagnosis of gestational diabetes mellitus (GDM). AIM To describe the current state of follow-up after GDM in primary care, in England. DESIGN AND SETTING A retrospective cohort study in 127 primary(More)
OBJECTIVE To report problems implementing a data quality programme in osteoporosis. DESIGN Analysis of data extracted using Morbidity Information Query and Export Syntax (MIQUEST) from participating general practices' systems and recommendations of practitioners who attended an action research workshop. SETTING Computerised general practices using(More)
BACKGROUND/AIMS Cases of chronic kidney disease (CKD) are defined by the estimated glomerular filtration rate (eGFR), calculated using the Modified Diet in Renal Disease (MDRD) or, more recently, the CKD Epidemiology Collaboration (CKD-EPI) formula. This study set out to promote a systematic approach to reporting CKD prevalence. DESIGN, SETTING,(More)
BACKGROUND Serum phosphate is a known risk factor for cardiovascular events and mortality in people with chronic kidney disease (CKD), however data on the association of these outcomes with serum phosphate in the general population are scarce. We investigate this relationship in people with and without CKD in a large community-based population. METHODS(More)
PURPOSE The Royal College of General Practitioners Research and Surveillance Centre (RCGP RSC) is one of the longest established primary care sentinel networks. In 2015, it established a new data and analysis hub at the University of Surrey. This paper evaluates the representativeness of the RCGP RSC network against the English population. PARTICIPANTS(More)
INTRODUCTION There is an increasing burden of gastro-oesophageal reflux disease (GORD) and Barrett's oesophagus (BO), paralleled by an increasing incidence of oesophageal adenocarcinoma. METHODS Using the General Practice Research Database, we derived the incidence GORD and BO and incidence of oesophageal cancer (OC) populations, between 1996 and 2005.(More)
BACKGROUND Chronic kidney disease (CKD) is a relatively newly recognised but common long-term condition affecting 5 to 10% of the population. Effective management of CKD, with emphasis on strict blood pressure (BP) control, reduces cardiovascular risk and slows the progression of CKD. There is currently an unprecedented rise in referral to specialist renal(More)
BACKGROUND The annual stroke rate in atrial fibrillation is around 5 per cent with increased risk in those with hypertension, diabetes, left ventricular dysfunction and other cardiovascular risk factors. This study set out to identify the patients with atrial fibrillation and modifiable risk factors for stroke. METHOD Analysis of practice computer data(More)
