OR WAIT null SECS

Packaging material has come a long way since the 140-count muslin that isstill the standard today for wrapping medical devices to be sterilized. There isa new face on muslin as it takes the form of Goretex and syntheticspunbond-meltdown-spunbond (SMS) and polyester/cotton blend materials. Thearrival of pouches, self-seal, low temperature, pouch rolls, Glassine papers,thermoplastic polymers, paper-plastic combinations and sterilization trays,cassettes, containers and container systems are as varied as the medicaldevice(s) that go in them. Adding to that is the challenge of whichsterilization method must be employed: Steam: gravity, dynamic air removal, dryheat, convection heat, hydrogen peroxide gas plasma or EO/ETO.
Deciding what goes where can be exhausting and frustrating. Certainly themanufacturers of sterilization packaging materials/systems can be of great help;however, if the right questions are not asked, the information that may begleaned may then be of no use in deciding which packaging material/system(s) tochoose.
|Medical Device||Sterilization Method||Suggested Packaging Material|
|Stainless steel instrument(s) Instrument set(s)||Steam||140-count muslin SMS Woven cotton/polyester-blend fabrics Pouches|
|Endoscopic instrument(s) Instrument set(s) plasma EO/ETO||Low temperature: Hydrogen peroxide gas||Hydrogen peroxide gas plasma: SMS Polyester-blend fabrics Low-temp SMS pouches EO/ETO: 140-count muslin SMS Polyester-blend fabrics Some crepe-type papers Thermoplastic polymers (Tyvek)|
|Glass syringes or other medical devices made of glass||Steam EO/ETO Hydrogen peroxide gas plasma||Steam: SMS pouches EO/ETO Hydrogen peroxide gas plasma Low-temp SMS pouches Thermoplastic polymers|
Evaluating the options for packaging material(s)/systems(s) does not have tobe difficult if a few considerations are made before making definitive choicesfor purchase. The investigation of packaging material/system(s) should includethe properties of the medical devices to be sterilized and the sterilizationmethod required. Charting the different packaging material(s)/system(s) andtheir respective uses in relation to the healthcare facilities medical device(s)can aide in making the right material choice. For example, see Tables 1 and 2.
Packaging material(s) come in varied sizes and shapes to accommodate thegrowing number of complex, innovative, odd shapes of new medical devices and thestandard application of basic instrumentation/medical devices. Medical packagingmanufacturer(s) have risen to the challenge for new packaging requirements; howto choose from so many sizes can be daunting when faced with budget constraintsthat will only allow a few standard choices to be made.
How to Choose
The first step in any purchasing practice is always investigation.Information required, but not limited to, before the first sales representativecall is:
Now it is time to call the local sales representative of the packagingmaterial/system manufacturer(s). A good rule of thumb is to include threemanufacturer(s) in the investigation process for best product/pricing) to set upa time to discuss the options and solutions available. Concise information onthe real needs of the healthcare facility can decrease the purchase of packagingmaterial/systems that will sit on a shelf not used and eventually become(s) adonated or discarded corporate expense. Consideration of all applications canavoid purchase of a multitude of sizes and configuration(s) bringing theselection(s) for warehouse stock or containers systems down to a few standardmanageable sizes.
Choosing the wrong packaging material/system can be devastating to a budgetby (but not limited to):
If fully informed choices are made concerning packaging material/systems formedical devices, instrumentation/medical devices are then protected andsterilized in packaging material/system(s) specific to the sterilizationmethod(s) approved and the budget responsibility to target/cut cost and useresources more effectively are met.
Materials management departments can help sort through and recommenddirection but should not be the sole researcher or decision maker in thepurchase of sterilization packaging material(s)/system(s). Cheaper is not alwaysbetter and does not always meet the needs of clinical use. If a less expensiveproduct can be found with equal or better properties than a marginally moreexpensive product, then certainly proceed with the less expensive product.Likewise, more expensive does not mean better. Weighing all options, cost andapplication sits on the shoulders of clinical end users, management of CPD/SPDdepartments and purchasing. While contract-buying groups are on the rise, beforechoosing a buying group, consideration must be given to products that will bestserve the patient population. Personnel and departments that should be involvedin choosing products/buying groups are:
Central sterile and sterile processing department personnel
Good choices do not come easy but bad ones can be a hard burden to bear forhealthcare and more importantly for patients. As in every case in any healthcarefacility, the patient and his or her well-being should be considered first, lastand everywhere in between. Cost reduction, while it is a very real concern andmust be handled delicately to meet the rising cost of healthcare, should notsupercede the best practice adhering to the best standards holding to thehighest moral and ethical responsibility to protect patients from potential andactual risk to their health and bodies.
