Learning Objectives
• The audience will be able to • Define the relation between bad sterilization
practices and hospital infections
• Identify and criticise the bad practices and propose solutions
• Integrate norms, SOPs and guidelines to their daily routine to achieve good practises
• Review the literature reporting the importance of good and bad sterilization practices

THERE IS NO RELATIONSHIP BETWEEN
HOSPITAL INFECTIONS AND
GOOD STERILIZATION PRACTICES!

Quality in health care
![Page 5: STERILIZATION PRACTICES AND HOSPITAL INFECTIONS](https://reader031.fdocuments.us/reader031/viewer/2022012421/6175f1bc0ddaf90b0b33a451/html5/thumbnails/5.jpg)
Evolution of quality in healthcare: From “To err is human” to public awareness
• Before 1995, no one was talking about patient safety • “To err is human” mentality
• In 2000, a small number in a few pioneering places had developed a strong commitment but, • Its impact was limited
• Most of health care was unaffected
• Since 2005, the majority of health care institutions are involved to some extent and public awareness has soared Leape L. 2005

• An outbreak of Serratia marcescens

Regulation about resterilization
The institutions that reprocess single-use devices should be regarded as disposable device manufacturers and
must meet all the requirements that apply to the disposable device manufacturers.

• 6 patients who were operated upon during the same day developed bacterial endophthalmitis on the following day
• 7 eyes were affected.
• 4 eyes eviscerated

Reasons for post cataract eendophtalmitis
• No centralization
• No adaptation
• No standardization
• No education
• Reuse of single use Phaco cassettes an tubings
• End result is infection!

Liquid sterilization ?
• An epidemic of infections after video-assisted surgery caused by rapidly growing mycobacteria (RGM) and involving 63 hospitals in the state of Rio de Janeiro, Brazil, occurred between 2006 and 2007
• High level disinfected instrument with 2% glutaraldehyde were used instead of sterilization
• 1051 possible cases!

THE ONLY REASON FOR STERILIZATION FAILURE
IN ALL THESE CASES IS
NON-STANDARD AND BAD STERILIZATION PRACTICES!!!

For good sterilization practices:
Good team leader
Educated and motivated CSSD staff
Well written and well understood SOPs
Routine control, validation, and documentation of sterilization process
Monitorization of compliance to the SOPs, guidelines and norms
