Grabe M, Bishop MC, Bjerkland-Johansen TE, Botto H, Cek M, Lobel B, Naber KG, Palou, J, Tenke, P, Wagenlehner F. Guidelines on Urological Infections. European Association of Urology 2009: 1-110. RATIONALE: Asymptomatic bacteriuria is seldom associated with adverse outcomes in people with indwelling catheters. Treatment of bacteriuria causes harms: increased short-term frequency of symptomatic infection, and re-infection with organisms of increased antimicrobial resistance.
NICE. Infection control. Prevention of healthcare-associated infections in primary and community care. The National Collaborating Centre for Nursing and Supportive Care and the Thames Valley University. 2003 http://guidance.nice.org.uk/CG139/Guidance Accessed 23.09.14. RATIONALE: This guideline originally stated that prophylactic antibiotics were also indicated for people with heart valve lesions, septal defects, patent ductus, or prosthetic valves. However, NICE state that this recommendation has been superseded by their 2008 guideline on prophylaxis of endocarditis, which states that prophylactic antibiotics are no longer required for people with those conditions requiring a catheter change.
