an interdisciplinary performance improvement study was conducted at a community hospital using the Focus-Plan, Do, Check, Act (Focus-PDCA is a registered service mark of Hospital Corporation of America) cycle. The study was designed to evaluate the effectiveness of the process of managing blood glucose (BG) levels in tube-fed intensive care unit patients. Interventions to be followed when BG by venipuncture was greater or equal to 200 mg/dL were defined. The threshold for evaluation for all interventions was 100%. Compliance with all interventions improved from 67% in quarter one to 100% in quarter four. Interdisciplinary design, collaboration, education, and communication helped achieve compliance. Community hospitals can benefit from a review of this process in implementing their own studies.
