Residual control chart for monitoring pediatrics hospital admission performances
This paper aims to demonstrate the use of pre whitening (PW) technique to handle the presence of autocorrelation on the statistical control charts, for 3-year (2008-2010) daily pediatrics (less than 4 years old) hospital admission.The PW technique has been implemented as an alternative procedure to...

| description | This paper aims to demonstrate the use of pre whitening (PW) technique to handle the presence of autocorrelation on the statistical control charts, for 3-year (2008-2010) daily pediatrics (less than 4 years old) hospital admission.The PW technique has been implemented as an alternative procedure to obtain residuals series which are statistically uncorrelated to each other.Results showed that there is a reduction in the number of out-of–control signals in residual series control chart as compared to the amount of the out-of–control signals on traditional statistical control chart before the use of PW technique.Thus, it is suggested that statistical control chart using residual series performs better when the original
pediatric hospital admission series are auto-correlated. In addition, it can be concluded that the Phase II (monitoring period) performance process is likely to follow the similar pattern of the Phase I (baseline period) process except for only one day on the 13th October 2009 that exceeds the upper control limit.This means that the pediatrics hospital admission on that particular day has not improved and fundamentally changed from what are expected in stable process. |
