Quality Quiz from Professor Cleary
Directors of Payne and Sufring Hospital have been concerned about the escalating number of incidents of people falling in the hospital hallways that has been reported in recent months, and have asked Dr. S. Low Ryaction to collect data and report trends to them.
After Dr. Ryaction had collected this data for a 30-day period, he shared the following chart with the board, noting that the average number of falls was 5.6 per day, and that the process was statistically in control, adding that the average number represented a relatively low percentage of hospital workers, patients, and visitors who populated the hospital on a daily basis.
Board member Arch N. Emee, alarmed about the potential for serious injury among those who fall in hospital hallways and on sidewalks, noted that the individuals section of the data, was in control, but the moving range section had one point out of control.
Dr. S. Low Ryaction dismisses the concern, saying that the moving range chart provides no useful information.
Is he correct?
