-
Results presented overall (total) and grouped into the practice tertiles defined by age-sex-standardised rate of elective gastroscopy (analysis of Hospital Episode Statistics (HES) data for England, 2006–2008).
-
*The coded diagnostic category is based on screening all diagnostic fields for relevant ICD-10 codes, assigning each patient to one category based on the most serious relevant diagnosis recorded in the episode containing the elective gastroscopy procedure.
