People with advanced disease approaching the end of life require sensitive consideration with regard to infection control procedures. Strict adherence to infection control guidelines designed for the acute hospital setting may not always be appropriate for terminal y il patients. This article examines the management of meticillin (methicillin)-resistant Staphylococcus aureus (MRSA) within the hospice patient population. It argues that limited evidence is available on which to base practice, noting that procedures and protocols vary across hospices. It is not the intention of the article to provide details of infection control procedures related to MRSA. That information is reported widely in the literature. Instead it wil concentrate on the prevalence of MRSA within the hospice setting and those aspects of infection control practice that have the potential to affect patients in the final stages of life, e.g. screening and isolation practices. Although it analyses the implications of MRSA precautions for hospice care practice, the findings are applicable to any environment in which dying patients receive care. Conflicts of interest: none for people near the end of their life. They also provide care for terminally ill people and infection control practices pertaining to a terminal y il patient population. It wil highlight the need for flexibility and physical, psychological, social and spiritual/ sensitivity with regard to certain aspects existential) and of er respite breaks for of infection control practice, which have the potential negatively to af ect patients in 2008a). Patients are admitted to hospices the final stage of life. Such practices include from all areas of the healthcare system. isolation of patients who test positive for evidence-based infection control practices is an essential aspect of caring for all patient populations, including those who are terminal y il . However, no standard 2001; Afif et al, 2002; Cepeda et al, 2005; hospice/palliative care infection prevention/ Suetens et al, 2006; Gaspard et al, 2009; 2004).

Decolonisation protocols usually consist of applying mupirocin ointment to the anterior nares three times a day for 5–7 days rates of MRSA (Johnson et al, 2005; Girou to eradicate nasal colonisation and applying an antiseptic body lotion, e.g. triclosan or chlorhexidine, et al, 2006; Cromer et al, 2008; Beggs et to eradicate skin colonisation.

Antibiotic creams for colonised wounds should not be used because of resistance. Local wound refer to Pratt et al’s (2007) best practice care policies should be followed. In the case of chronic wounds, e.g. pressure ulcers and leg ulcers, advice should be sought. Topical agents may not be appropriate in the case of invasive devices (e.g. percutaneous wearing gloves routinely requires specific endoscopic gastrostomy tubes or urinary catheters) as there is a risk of degeneration.
