Introduction: Nosocomial infections are an important problem in modern hosp
itals. The prevalence in German intensive care units is 15.3%. Hand washing
or hand disinfection is believed to be the most important means of prevent
ing nosocomial infections. We wished to answer the following questions: 1.
How good is the compliance of hand hygiene on intensive care units? 2. Is c
ompliance associated with the patient/nurse-ratio?
Method: In a study of 8 intensive care units the compliance of hand hygiene
was observed on two occasions, once in May 1996 and again in November 1997
. The prime necessity for hand disinfection occurred when handling ventilat
ion devices, intravascular catheters, urinary catheters and dressings. In a
ddition the patient/nurse-ratio was calculated.
Results: A total of 1,879 infection-relevant handlings were observed. The c
ompliance of hand hygiene ranged from 25.7 to 83.2% (mean 55.2%). The most
commonly observed handlings were the manipulation of venous catheters (52.7
%), the highest compliance was observed with the manipulation of ventilatio
n equipment (91.8%). With a better patient nurse ratio the compliance did n
ot improve but remained the same or was even reduced.
Discussion: The compliance of hand disinfection is similar to other study r
esults, but on some intensive care units there was considerable room for im
provement. In this study the compliance of hand hygiene is more of a consta
nt factor in individual intensive care units than associated with the patie
nt/nurse-ratio.
