Constipation is one of the most common outpatient diagnoses in primary care and gastroenterology clinics.
However, there is limited data on the inpatient burden of constipation in the United States.
Dr Anthony Lembo and colleagues from Massachusetts, USA evaluated inpatient admission rates, length of stay, and associated costs related to constipation from 1997 to 2010.
The research team analyzed the National Inpatient Sample Database for all patients in which constipation was the principal discharge diagnosis from 1997 to 2010.

The statistical significance of the difference in the number of hospital discharges, length of stay, and hospital costs over the study period was determined by utilizing the Spearman's coefficient to describe various trends.
Between 1997 and 2010, the team noted that the number of hospitalizations for patients with a primary discharge diagnosis of constipation increased from 21,190 patients to 48,450, whereas the mean length of hospital stay increased only slightly from 3.0 days to 3.1 days.
The mean charges per hospital discharge for constipation increased from $8869 in 1997 to $17,518 in 2010, whereas the total costs increased from $188,109,249 in 1997 to $851,713,263 in 2010.
Although the elderly accounted for the largest percentage of constipation discharges, patients in the 1–17 years age group had the highest frequency of constipation per 10,000 discharges.
Dr Lembo's team concludes, "The number of inpatient discharges for constipation and associated costs has significantly increased between 1997 and 2010."
