Abstract
BACKGROUND:
Gastro-oesophageal reflux disease (GERD) is a common diagnosis in primary care; however, there has been no comprehensive review of the epidemiology of GERD in this setting.
AIM:
To review systematically articles that used the General Practice Research Database to study the epidemiology of GERD.
METHODS:
Systematic literature searches.
RESULTS:
Seventeen articles fulfilled the inclusion criteria. The incidence of GERD in primary care was 4.5 new diagnoses per 1000 person-years in 1996 (95% CI: 4.4-4.7). A new diagnosis of GERD was associated with being overweight, obese or an ex-smoker. Prior diagnoses of ischaemic heart disease, peptic ulcer disease, nonspecific chest pain, nonspecific abdominal pain, chronic obstructive pulmonary disease and asthma were associated with a subsequent new GERD diagnosis. A first diagnosis of GERD was associated with an increased risk of a subsequent diagnosis of oesophageal adenocarcinoma, oesophageal stricture, chronic cough, sinusitis, chest pain, angina, gallbladder disease, irritable bowel syndrome or sleep problems. Mortality may be higher in patients with a GERD diagnosis than in those without in the first year after diagnosis, but not long term.
CONCLUSION:
The General Practice Research Database is an effective way of studying the epidemiology of GERD in a large population-based primary care setting.
