Another reuse study

(picked this up from the dialysis advocates site: http://dialysisadvocates.com/)

"Among reports comparing the use of formaldehyde as the reuse germicide with single-use practices, one study revealed a 12% decreased mortality risk in the reuse group (11). The six other studies did not demonstrate significant differences in mortality between the two practices (12,15,17–20).

Among studies that compared the use of glutaraldehyde as the reuse germicide with single-use practices, only one study revealed a 13% increased mortality risk in the reuse group (17). Five other reports did not demonstrate significant differences in mortality between the two practices (12,15,18–20).

Similarly, among studies that compared the use of peracetic acid as the reuse germicide with single-use dialyzer practices, two studies revealed an increase in mortality by 10 to 17% (12,17). One study of longer follow-up duration revealed a 15% higher death risk in the reuse group in the first 2 years of this practice, which abated in the subsequent 3-year follow-up period (18). Three other studies did not reveal any mortality difference between the two groups (15,19,20).

Four studies grouped a combination of reuse methods and compared this practice with dialyzer single use (10,13,18,21). Only two studies demonstrated a 5 to 25% increased mortality risk in the reuse group (13,21)."

"The risk for hospitalizations between single-use and reuse practices was assessed in three studies (13,14,20). When formaldehyde was used, one study documented no difference (14), whereas the other two documented a 29 to 75% increase in hospitalization rates in the reuse groups (13,20). With glutaraldehyde, two studies reported no difference in the rate of hospitalizations (13,14). When peracetic acid was used, three studies documented an 11 to 28% increase in hospitalization rate in reuse groups (13,14,20)."
