AIMS To investigate the range of methods used to validate diagnoses in the General Practice Research Database (GPRD), to summarize findings and to assess the quality of these validations. METHODS A systematic literature review was performed by searching PubMed and Embase for publications using GPRD data published between 1987 and April 2008. Additional publications were identified from conference proceedings, back issues of relevant journals, bibliographies of retrieved publications and relevant websites. Publications that reported attempts to validate disease diagnoses recorded in the GPRD were included. RESULTS We identified 212 publications, often validating more than one diagnosis. In total, 357 validations investigating 183 different diagnoses met our inclusion criteria. Of these, 303 (85%) utilized data from outside the GPRD to validate diagnoses. The remainder utilized only data recorded in the database. The median proportion of cases with a confirmed diagnosis was 89% (range 24-100%). Details of validation methods and results were often incomplete. CONCLUSIONS A number of methods have been used to assess validity. Overall, estimates of validity were high. However, the quality of reporting of the validations was often inadequate to permit a clear interpretation. Not all methods provided a quantitative estimate of validity and most methods considered only the positive predictive value of a set of diagnostic codes in a highly selected group of cases. We make recommendations for methodology and reporting to strengthen further the use of the GPRD in research.read more

The epidemiology of cirrhosis and abnormal liver function in the general population of the UK
TL;DR: This thesis utilises two distinct datasets to examine separate areas of interest in the epidemiology of liver disease in the UK and uses Poisson regression to estimate incidence rate ratios and describe trends in alcoholic and non-alcohol-related cirrhosis.

TL;DR: Aurum estimates appeared more consistent with external sources and may be useful for monitoring population musculoskeletal health and healthcare demand, but they remain sensitive to analytic decisions and data quality.

Longitudinal analysis of the relationship between motor and psychiatric symptoms in idiopathic dystonia
TL;DR: A bidirectional relationship between psychiatric disorders and dystonia, particularly with mood disorders is suggested, with psychiatric disorders potentially forming prodromal symptoms of idiopathic dySTONia.

Epidemiology of fractures in England and Wales
TL;DR: Varying patterns of fracture incidence were observed with increasing age; whereas some fractures became more common in later life (vertebral, distal forearm, hip, proximal humerus, rib, clavicle, pelvis), others were more frequent in childhood and young adulthood.

Recent trends in physician diagnosed COPD in women and men in the UK

TL;DR: While prevalence rates of COPD in the UK seem to have peaked in men, they are continuing to rise in women, and this trend, together with the ageing of the population and the long term cumulative effect of pack-years of smoking in women is likely to increase the present burden of COPd in theUK.
