Sharq El Madina Hospital was constructed at 1977 and started the open cardiothoracic surgery
activities at 1996 .
![Page 4: Copy of 6 Sigma Project to Reduce Open Heart Wound Site Infection-with Photos](https://reader037.vdocuments.net/reader037/viewer/2022110115/549dbd49ac795951768b45af/html5/thumbnails/4.jpg)
The cardiology & open cardiothoracic surgery became the core competence of the hospital which is evident by performing about 10,000 open heart surgeries & about 17,000 diagnostic & therapeutic cardiac catheter in the period from 1996 – 2007.

The surveillance rate for open heart surgical site wound infection suddenly raised from 3.8%(the global accepted ratio 5.1 %) in December 2010 to 8.1% in Jan 2011 &11.1% in Feb. 2011
Our reputation as center for open heart surgery in Alex was threatened
Infection control team started to discover the root causes
We use the six sigma steps in our project

Project benefitsProject benefitsFinancial and operational Financial and operational
benefitsbenefitsEach post operative infection cause
readmission for debridement and closure of wound and approximately increase LOS by 10 days at cost of an additional 6000 LE in extra charge
An averaged 5 infections per month ,approximately 60 infection per year at a total cost of 360,000 LE
If infection decreased to 4% a saving of about 235,000 LE will take place

problem statement The surveillance for surgical site infection
of post operative cardiac surgery show an increase of infection rate on Feb.2011 to 11.1% ( about 2.7 )
The accepted infection rate is up to 5.1%This leads to increase rate of
readmission to cardiac center with raising cost
This may lead to loss of reputation
