Background: Constipation is a common diagnosis made in the pediatric emergency department (ED). Specific evidence-based standards for evaluation and treatment are lacking.
Objective: To describe variation in evaluation and treatment of constipation and characteristics and treatments associated with improvement.
Methods: This single-site descriptive study examined constipated children discharged from the ED. Chart review provided history, examination, evaluation, and treatment. Symptoms and on-going treatment were assessed by telephone interview at 4 to 6 weeks. Patients were dichotomized to poor versus adequate responders. Poor responders had 2 or more of the following: overall constipation, persistent presenting symptom, bowel movement frequency of less than once every other day, painful defecation, and/or abdominal pain.
Results: The study group had 121 patients, with mean age of 6.4 years; 54% were female. Abdominal pain was the most common complaint (66%); 46% reported hard/infrequent stools. Most (67%) had symptoms for less than 1 week. Many (41%) previously sought care for the same problem. Most (70%) had abdominal radiographs. One third received an enema in the ED, and most patients were prescribed laxatives, most commonly polyethylene glycol (80%). After an enema, 28% were discharged without constipation medication. At follow-up, 35% were using laxatives, and 27% had sought additional care. Nearly half (42%) were poor responders. Poor responders were younger (5.1 vs. 7.3 years; P < 0.01). There was no difference in response based upon sex, duration of symptoms, or ED treatment.
Conclusions: Although older children are more likely to improve, many constipated children continue to have symptoms. Type of ED therapy is unrelated to on-going symptoms at 4 to 6 weeks.
