Prevention of urinary tract infections in nursing homes: lack of evidence-based prescription?

<p>Abstract</p> <p>Background</p> <p>Urinary tract infections (UTIs, including upper and lower symptomatic) are the most common infections in nursing homes and prevention may reduce patient suffering, antibiotic use and resistance. The spectre of agents used in preventing UTIs in nursing homes is scarcely documented and the aim of this study was to explore which agents are prescribed for this purpose.</p> <p>Methods</p> <p>We conducted a one-day, point-prevalence study in 44 Norwegian nursing homes during April-May 2006. Nursing home residents prescribed any agent for UTI prophylaxis were included. Information recorded was type of agent and dose, patient age and gender, together with nursing home characteristics. Appropriateness of prophylactic prescribing was evaluated with references to evidence in the literature and current national guidelines.</p> <p>Results</p> <p>The study included 1473 residents. 18% (n = 269) of the residents had at least one agent recorded as prophylaxis of UTI, varying between 0-50% among the nursing homes. Methenamine was used by 48% of residents prescribed prophylaxis, vitamin C by 32%, and cranberry products by 10%. Estrogens were used by 30% but only one third was for vaginal administration. Trimethoprim and nitrofurantoin were used as prophylaxis by 5% and 4%, respectively.</p> <p>Conclusions</p> <p>The agents frequently prescribed to prevent UTIs in Norwegian nursing homes lack documented efficacy including methenamine and vitamin C. Recommended agents like trimethoprim, nitrofurantoin and vaginal estrogens are infrequently used. We conclude that prescribing of prophylactic agents for UTIs in nursing homes is not evidence-based.</p

Three-year prevalence of healthcare-associated infections in Dutch nursing homes

From November 2007 for a period of three years (2007-2009), we conducted an annual one-day prevalence study of healthcare-associated infections (HAIs) among nursing home residents in the Nijmegen region of The Netherlands. In the absence of national HAI definitions applicable to the nursing home setting, we used modified definitions based on US Centers for Disease Control and Prevention criteria for bloodstream infection, lower respiratory tract infection, bacterial conjunctivitis, and gastroenteritis. For the surveillance of urinary tract infection (UTI), criteria established by the Dutch Association of Elderly Care Physicians were used. Resident characteristics were recorded and data collection was performed by the attending elderly care physicians. For the three-year period, 1275, 1323, and 1772 nursing home residents were included, resulting in a prevalence of HAIs of 6.7%, 7.6% and 7.6%, in 2007, 2008 and 2009, respectively. The demographics with respect to age (mean 81 years) and sex (31% men, 69% women) were almost identical in all three years. UTI was the most prevalent HAI with 3.5%, 4.2%, and 4.1% respectively. Most HAIs occurred among residents of rehabilitation units. The prevalence of HAIs varied by nursing home (range: 0.0-32.4%). We present the results of the first prevalence study of HAIs in Dutch nursing homes. Point prevalence studies of HAIs, as part of a quality improvement cycle, are an important cornerstone of infection control programmes in nursing homes, allowing us to further increase patient safety efforts in this setting
