An eight-step method for assessing diagnostic data quality in practice: chronic obstructive pulmonary disease as an exemplar

Does a higher 'quality points' score mean better care in stroke? An audit of general practice medical records

“…Problems with the PPV of computer diagnoses, and variation between computer systems, are not unique to stroke; we have reported similar problems with chronic obstructive pulmonary disease 32 and osteoporosis. 33 These problems may exist more broadly.…”

Variation in clinical coding lists in UK general practice: a barrier to consistent data entry?

“…For example, children are all too easily given the diagnosis of 'chronic obstructive pulmonary disease' (COPD), a disease usually found in male smokers over 40 years old, because it appears as 'bronchitis' on the picking list used by clinicians looking to code acute bronchitis. 2 We have also noted varying use of different coding hierarchies in mental health problems 3 and ethnicity. 4 The Read code includes two differing psychosis sections, one based on the International Classification of Diseases (ICD) and one that is specific to the Read classification.…”

Using Electronic Dental Record Data for Research

“…Second, EDRs do not always store data in structured form, allow users to store the same or similar information in multiple places, and validate data inconsistently. Third, like EHR data (Hogan and Wagner, 1997;Faulconer and de Lusignan, 2004), EDR data often vary in their accuracy and are difficult to extract systematically. Last, clinical data rarely capture the information that is necessary to address a study's specific aim(s) adequately (Maupomé et al, 2006).…”
