RESUMEN
BACKGROUND: Mobile ultraviolet (UV) disinfection uses UV-C light to render microorganisms nonviable and reduce environmental transmission of pathogens in hospital settings. Optimal strategies for deployment must consider the cost, physical layout, and staffing resources. The aim of this quality improvement study was to increase UV disinfection utilization by developing novel deployment strategies without adding resources. METHODS: A novel deployment strategy and tools were developed by a multidisciplinary group that included infection prevention, environmental services, and nursing unit staff. Utilization was tracked via a manufacturer-supported database. The infection prevention team analyzed the weekly UV disinfection minutes, cycles, and proportions of cycles completed in defined areas across 4 periods: baseline, pilot, baseline 2, and intervention. RESULTS: The median (range) disinfection cycle times per week during a geographically confined pilot (4,985 minutes [3,476-6,551] minutes) and the intervention period (1,454 [512-3,085] minutes) were lower than either baseline period (5,394 [3,953-6,987] and 6,641 [2,830-7,276] minutes, respectively). Cycles per week were lower in the intervention period than in the preceding 3 periods. CONCLUSIONS: Use of UV disinfection in acute care settings should be guided by multidisciplinary groups balancing resources against efficacy and using tailored tools to promote efficiency.
RESUMEN
OBJECTIVE: To evaluate the impact of the WellingTonne Challenge. DESIGN: Before-after study. SETTING: The National Action Agenda for the prevention and control of obesity in Australia identified community action and development as a key theme. The WellingTonne Challenge was a whole-of-community project designed to support a small rural community to lose weight and reduce their risk of chronic disease. PARTICIPANTS: Adult residents of the Wellington Local Government Area who were overweight or obese. RESULTS: The project successfully engaged the community with around 10% of the target group formally participating in the Challenge. Participants achieved a weight reduction of around 3 kg each, as well as positive changes in diet and physical activity. A total of 59% of those who signed up for the Challenge achieved an accumulated loss of 687 kg at the end of the 12-week program--less than the community goal of 1000 kg. CONCLUSION: The WellingTonne Challenge is a promising intervention. Wider implementation of this approach in other small rural communities might make a significant contribution to the national effort. The opportunity should be taken to undertake a more rigorous evaluation to determine whether this approach benefits communities in the longer term.
