Swab culture monitoring of automated endoscope reprocessors after high-level disinfection

Table 1 Rate of positive swab culture from the automated endoscope reprocessor after gastroscope and colonoscope reprocessing n (%)

Category	AER	P value
Gastroscope (n = 300)	6 (2.0)	NS
Colonoscope (n = 120)	1 (0.8)	NS
Total (n = 420)	7 (1.7)	NS

AER: Automated endoscope reprocessor; NS: Not significant.
