Number of diagnoses adds to more than the number of inpatients as a patient could have more than one diagnosis. The top 5 diagnostic categories per year and overall are highlighted;
This is a grouping of all the other minor diagnostic categories seen;
A statistically significant linear decrease over the years [Inpatient: Inflammatory bowel disease, other diseases of colon/anus/rectum and iron studies related disorders (P = 0.015, 0.040 and < 0.001, respectively); Outpatient: Abdominal pain of unknown cause and other functional disease (P < 0.001 for both)];
A statistically significant linear increase over the years [Inpatient: Liver disease and constipation (P = 0.010 and 0.001, respectively); Outpatient: Liver disease, family history of bowel cancer, constipation and iron studies related disorders (P = 0.001, < 0.001, 0.003 and 0.002, respectively)].
