The aim of this study was to identify the consequences of healthcare-associated infections in Norwegian nursing homes, to include debilitation, hospital transfer and mortality. We followed the residents of six nursing homes in two major cities in Norway during the period October 2004 to March 2005. For each resident with infection we randomly selected two controls among residents who did not have an infection. Cases and the controls were followed for 30 days as a cohort in order to measure the incidence of complications and risk ratio (RR) in the two groups. The incidence of infection was 5.2 per 1000 resident-days. After 30 days follow-up 10.9% of residents who had acquired infection demonstrated a reduction in overall physical condition compared with 4.8% in the unexposed group (RR: 2.3). Altogether 13.0% of residents with infections were admitted to hospital compared with 1.4% in the unexposed group (RR 9.2), and 16.1% residents with infections died in the nursing home during follow-up compared with 2.4% in the unexposed group (RR: 6.6). Residents with lower respiratory tract infections demonstrated higher morbidity and mortality. In conclusion, healthcare-associated infections cause severe consequences for people living in nursing homes, including debilitation, hospital admission and death.
