Aims To apply cumulative sum (CUSUM) in monitoring performance of surgeons in cataract surgery and to evaluate the response of performance to intervention. Method A CUSUM analysis was applied to 80 ...

Objective The learning curve–cumulative summation (LC-CUSUM) test allows for quantitative and individual assessments of the learning process. In this study, we evaluated the process of skill ...

To improve patient safety, surgeons can continually monitor the surgical outcomes of their patients. To this end, they can use statistical process control tools, which primarily originated in the ...

Figure 1 Example LC-CUSUM and SPRT-CUSUM curves: (A) The curve of one resident who attained proficiency after 18 procedures. The three failures detected in the post-proficiency SPRT trace (upward ...

The results from the CUSUM test and CUSUM squared test show significant divergence in the stability of money demand among the sixteen (16) countries in West Africa. From both the CUSUM and CUSUM ...

We propose an energy efficient distributed cooperative Change Detection scheme called DualCUSUM based on Page's CUSUM algorithm. In the algorithm, each sensor runs a CUSUM and transmits only when the ...

Juicy smoked sausage and tender cabbage come together for an unforgettable (and undeniably easy) dinner in just minutes. Kimberly Holland is a writer and editor with 17 years of experience in food, ...

Results: CUSUM-OT showed that the operation time improved significantly after the 161 th case. RA-CUSUM analysis allowed to break the CRS learning curve into three different phases: phase 1, “the ...
