Variations in the reporting of endoscopies by different endoscopists

Area of Science:

• Gastroenterology
• Medical Auditing

Background:

• Endoscopic procedures like gastroscopy and colonoscopy are crucial diagnostic tools.
• Variability in diagnostic reporting can affect patient management and outcomes.

Purpose of the Study:

• To audit and assess the consistency of endoscopic reporting between different endoscopists.
• To identify variations in the diagnosis of common conditions during gastroscopies and colonoscopies.

Main Methods:

• A retrospective audit of all gastroscopies and colonoscopies performed over one year in two UK teaching hospitals.
• Analysis of endoscopic diagnoses from hospital databases using chi-squared statistical tests.

Main Results:

• Significant variability was observed in the frequency of reported diagnoses among endoscopists.
• This variation was highly significant for conditions like peptic ulceration (2-10%) and colonic polyps (16-45%).
• Differences could not be attributed to patient case-mix or random chance.

Conclusions:

• There is substantial inconsistency in endoscopic diagnostic reporting by different specialists.
• This variability has potential major implications for patient care and safety.
• Enhanced training in endoscopic interpretation is recommended to improve diagnostic accuracy.
