Three consecutive audits to achieve acceptable colonoscopy completion rates.

OBJECTIVE To compare the acceptable colonoscopy completion rates in three successive audits, identifying the reasons for failure of completion and rectifying them to improve the performance at our endoscopy unit. METHODS Study was conducted at Endoscopy unit of Medical Unit One Civil Hospital Karachi. The first audit was conducted retrospectively on the colonoscopy results, done from November 2004 to November 2005. As the information was incomplete, a performa was designed for the next prospective audit from December 2005 to November 2006. The shortcomings found in the results of this audit were improved in the third audit done prospectively from December 2006 to November 2007. RESULTS In the first audit 164 patients (111 male) underwent colonoscopy. The mean age was 40 +/- 10.08 years. The overall caecal intubation rate was 55%, but adjusted caecal intubation was not calculated because of inadequate documentation. In the second audit, 119 patients (66 male) underwent colonoscopy. The mean age was 45 +/- 10.17 years. After implementing changes the overall crude caecal intubation rate was 54.8% and the adjusted caecal intubation rate was 75% with exclusion of strictures and poor preparation. In the third audit, 122 patients (58 males) underwent colonoscopy. The mean age was 38 +/- 11.07 years. With further improvement in methodology the overall crude caecal intubation rate was (80.3%) and the adjusted caecal intubation rate was (98%). CONCLUSION These audits allowed us to evaluate our endoscopy services and to detect the short comings and deviation from standard techniques and hence improving the performance in the subsequent year for the benefit of patients.
