Analysis of a surgical procedure for patients with heart disease
Our client was a public hospital interested in analyzing the processes involved when treating patients with heart disease.
Challenge
To optimize the time that passes between diagnostic, performing the necessary tests, and the actual surgical procedure
One area of focus was to identify the impact that the different test equipment have in the overall duration of the process and find opportunities to reduce it.
Another focus was the comparison between regular and emergency cases, and understanding if the patients age has an impact too.
Solution
We learnt that traces that followed the process had an average duration 50% longer than those that did not
This suggested that there was an opportunity to redesign in the procedure to result in shorter lead times, but further investigation into the strict safety policies was needed
(At the time, only 20% of cases followed the standard process).
A later redesign based on the findings yielded positive results.
