[Open access colonoscopy: do primary care physicians use it properly?].
BACKGROUND
Open access endoscopy facilitates the performance of colonoscopy on a physician's request, without a prior consultation with a gastroenterologist.


OBJECTIVE
To investigate: (1) the rates of relevant endoscopic findings in patients referred by family physicians compared to other specialists; (2) whether there is overuse of open-access colonoscopy in our country where the examination is free of charge for the patient; (3) whether a high rate of pre-malignant and malignant incidental findings might justify a more liberal approach to the indications of colonoscopy.


METHODS
Prospective study including all consecutive ambulatory patients referred for open access colonoscopy. The indication for the examination was tabulated according to the American Society for Gastrointestinal Endoscopy (ASGE) guidelines. Endoscopic findings were classified into relevant or normal; each relevant finding was correlated with the indication for which the examination was performed.


RESULTS
A total of 34.2% of patients had a colonoscopy performed for an inappropriate indication; family physicians had a slightly higher rate of appropriate indications compared with the other specialists. However, a relevant endoscopic finding was diagnosed only in 14.0% of their referred cases, compared with 22.8% of the other specialists (p = 0.032). Polyps larger than 5 mm or a malignant tumor were diagnosed in 20.7% of the colonoscopies; 19 out of the 83 cases (23%) were diagnosed in examinations performed for inappropriate indications.


CONCLUSIONS
It was found that 34% of the colonoscopies were performed for inappropriate indications. A higher proportion of relevant endoscopic findings was diagnosed among patients referred by surgeons, oncologists and internists as compared with those referred by family physicians. Considering that as much as 23% of polyps and malignant tumors were found in cases performed for inappropriate indications, we suggest that a liberal approach to the indications for colonoscopy--probably age over 50 years--may benefit the patients.
