Treatment Satisfaction With Current Medications for Chronic Constipation: An Internet Survey of Japanese Patients.

GOALS

This survey aims to determine relevant patient characteristics, treatment satisfaction, and bothersome symptoms in Japanese patients with chronic constipation (CC) treated at medical institutions.

BACKGROUND

Epidemiological surveys of Japanese patients with CC are limited.

STUDY

This internet survey, conducted in 2017, included 500 adults (selected from 589 respondents to match age composition ratio in Japan) who experienced constipation-like symptoms for ≥6 months, were treated at medical institutions for symptoms, and were taking any prescribed medication.

RESULTS

Of 500 patients, 65.6% were female and 62.6% had experienced constipation for >10 years. Abdominal bloating, infrequent bowel movement, hard consistency of stool, and difficulty of defecation were the most frequently reported and most bothersome symptoms in males and females. Overall, 29% of patients were satisfied with treatment (36% of males, 26% of females); the individual major CC symptom with the highest level of treatment satisfaction was infrequent bowel movement (31% of total, 45% of males, 26% of females). The level of treatment satisfaction for most individual major CC symptoms was lower in females than in males, and overall treatment satisfaction by therapeutic categories ranged from 16% to 46%. Mean overall treatment satisfaction, as well as mean treatment satisfaction for each major symptom, decreased with increasing number of treatments.

CONCLUSIONS

The survey results suggest that conventional treatment options were not effective enough to improve bothersome symptoms or treatment satisfaction. Treatment selection that is tailored to individual symptoms and takes patient characteristics into consideration may be key to improving patients' treatment satisfaction.
