Long-term Follow Up of Patients in the Birmingham and Lambeth Liver Evaluation Strategies (BALLETS) Study
This study will follow-up a cohort of patients from the Birmingham and Lambeth Liver Evaluation Strategies (BALLETS) study using a database search based on their individual National Health Service (NHS) numbers. The investigators will interrogate the Hospital Episode Statistics database and the Office of National Statistics database, and examine three categories of end points: death, inpatient attendance primarily due to liver disease, and outpatient attendance primarily due to liver disease.
A logistic regression analysis will then be conducted to determine associations between these end points and the presence, and degree, of fatty liver in the original BALLETS study, adjusted for age, sex, alcohol intake, BMI, and baseline ALT measurement.
Studieoversikt
Detaljert beskrivelse
The Birmingham and Lambeth Liver Evaluation Strategies (BALLETS) study was a prospective study of people in General Practice who had an abnormal liver function test result. Recruitment took place between 2005 and 2008, and patients were able to be grouped into four primary categories: hepato-cellular disease, hepato-biliary disease, tumour, non-specific with or without fatty liver. This study will focus on the fourth, non-specific, group of which there were 1,237 patients.
This study will follow-up this cohort of patients using a database search based on their individual National Health Service (NHS) numbers. The investigators will interrogate the Hospital Episode Statistics database (health outcomes) and the Office of National Statistics database (death), and examine three categories of end points: death, inpatient attendance primarily due to liver disease, and outpatient attendance primarily due to liver disease. Deaths would be sub-categorised as including liver disease, or not.
A logistic regression analysis will then be conducted to determine associations between these end points and the presence, and degree, of fatty liver in the original BALLETS study, with adjustment for age and sex. Similar age- and sex-adjusted analyses will be conducted to investigate the association with other patient risk factors - alcohol intake and BMI. The analyses will be repeated incorporating an additional adjustment for baseline Alanine Aminotransferase (ALT) measurement.
