The Journal of hospital infection

This paper arises out of two workshop sessions held at the fourth meeting of the Federation of Infection Societies, Manchester, 1997. The aims of the workshops were, first, to identify the factors which impede the process of translating research findings into infection control practice and second, to suggest how these barriers may be overcome. ⋯ This lends structure to our exploration of the evidence underlying infection control guidance and the reasons why such guidance often does not result in appropriate action by healthcare workers. The strengths and weaknesses of each stage of the process are examined, using examples provided by participants at the workshop.

To investigate early onset pneumonia in a neurosurgical intensive care unit, we studied a cohort of patients over a 13-month period and compared neurotrauma (T) with non-neurotrauma (NT) patients. Data were abstracted from the infection surveillance database. Five hundred and sixty-five adults were hospitalized in the neurosurgical intensive care unit. 57.9% had trauma and 129 patients developed 152 episodes of pneumonia. ⋯ EOP was caused by Staphylococcus aureus (33%), Haemophilus spp. (23%), other Gram-positive cocci (22%), and other Gram-negative bacilli (GNB) (19%); whereas after the third day GNB other than Haemophilus spp. accounted for 45.4% of isolates (P = 0.11). This large series confirms the high incidence of EOP in neurosurgical intensive care units, particularly among trauma patients, in relation to risk factors different from those seen in other intensive care patients. Further studies are needed to elaborate specific preventive measures during early care.

Methicillin-resistant Staphylococcus aureus (MRSA) is increasingly reported as a hospital-acquired pathogen in intensive care units (ICUs). The inconsistent application of hygiene measures by healthcare workers accounts largely for the epidemic dissemination of such resistant strains. The efficacy of a control programme to prevent spread of MRSA was assessed in our paediatric ICU (PICU) from April 1992 to December 1995. ⋯ The nosocomial infection rates caused by other micro-organisms decreased among the transplant patients from 64.8-33.2/1000 transplanted PD (P = 0.009) between 1994 and 1995. At the same time, we observed a slight increase of infections in non-transplanted patients, which may have been due to the effect of increased overall workload on those patients who were supposed to have fewer nosocomial risk factors. We conclude that implementation of infection control measures directed towards limiting person-to-person spread was effective in controlling high MRSA infection rates in a PICU, but it is important to allow enough time for staff to carry out hygiene practices thoroughly.
