ABSTRACT
OBJECTIVE: To determine the effectiveness of ultraviolet (UV) environmental disinfection system on rates of hospital-acquired vancomycin-resistant enterococcus (VRE) and Clostridium difficile. DESIGN: Using active surveillance and an interrupted time-series design, hospital-acquired acquisition of VRE and C. difficile on a bone marrow transplant (BMT) unit were examined before and after implementation of terminal disinfection with UV on all rooms regardless of isolation status of patients. The main outcomes were hospital-based acquisition measured through (1) active surveillance: admission, weekly, and discharge screening for VRE and toxigenic C. difficile (TCD) and (2) clinical surveillance: incidence of VRE and CDI on the unit. SETTING: Bone marrow transplant unit at a tertiary-care cancer center.ParticipantsStem cell transplant (SCT) recipients.InterventionTerminal disinfection of all rooms with UV regardless of isolation status of patients. RESULTS: During the 20-month study period, 579 patients had 704 admissions to the BMT unit, and 2,160 surveillance tests were performed. No change in level or trend in the incidence of VRE (trend incidence rate ratio [IRR], 0.96; 95% confidence interval [CI], 0.81-1.14; level IRR, 1.34; 95% CI, 0.37-1.18) or C. difficile (trend IRR, 1.08; 95% CI, 0.89-1.31; level IRR, 0.51; 95% CI, 0.13-2.11) was observed after the intervention. CONCLUSIONS: Utilization of UV disinfection to supplement routine terminal cleaning of rooms was not effective in reducing hospital-acquired VRE and C. difficile among SCT recipients.

Cancer and cancer therapies cause side effects that prevent patients from consuming adequate amounts of food. As evidenced by patient meal consumption studies conducted at patients' bedside, only 39 percent of patients surveyed consumed greater than 50 percent of their main entree. The Food and Nutrition Services Department at Memorial Sloan-Kettering Cancer Center used the organization's performance improvement process, STRAIGHT-A, to develop and execute a room service program designed to increase patient meal consumption and improve patient meal satisfaction A multidisciplinary task force developed policies and procedures and tested new menu items as part of the room service plan. After program implementation, 88 percent of patients surveyed consumed greater than 50 percent of their main entree.
