Prior to CLIA ’88 (Clinical Laboratory Improvement Amendments of 1988) only laboratories participating in interstate commerce underwent inspections. Since the enactment of CLIA ’88, all laboratories are subject to inspection, and all non-waived laboratories are inspected. CLIA has the right to appear at any point in time to inspect a lab.
There are two types of inspections for non-waived labs: routine and non-routine
Routine inspections take place every two years as mandated by CLIA, regardless of which agency is responsible for the inspection. If a lab has a Certificate of Compliance, CLIA will be the inspecting agency. If the laboratory has opted for a Certificate of Accreditation from one of the approved accrediting agencies, that agency will perform the inspection. Either way, the inspections are set on a two year cycle and the renewal of the laboratory’s certificate is dependent upon successful completion of the inspection. If no deficiencies are cited, the certificate will be renewed very soon after the inspection is completed. If deficiencies are cited during the inspection, the laboratory will receive a deficiency report and will be given a timeline to submit a plan of correction. Once the plan of correction is accepted by the inspecting agency, the certificate will be renewed. Failure to achieve a successful conclusion to the inspection process will result in the cancellation of the lab’s certificate, and therefore loss of privileges to do lab testing and to bill for lab testing.
The inspection cycle differs slightly for a newly set-up laboratory. CLIA or the accrediting agency will come in to do an inspection after the lab has been in operation for 3 – 6 months to ensure everything required is in place and all regulations are being followed. CLIA and the accrediting agencies do not inspect prior to the lab starting testing operations because they want the lab to generate data for them to review upon their inspection.
Most medical facilities have refrigerators, but do you know the guidelines surrounding refrigerators and freezers? Laboratory Consultant Libby Knollmeyer debuts on Manage My Practice with answers to your most-asked questions.
What kind of refrigerator do I need?
If you need to COOL only…
In most cases, a good quality household refrigerator will suffice if the cubic footage is adequate for what needs to be stored and nothing has to be frozen.
If you need to FREEZE and COOL…
If frozen storage is required, either a NON self-defrosting freezer or a freezer designed to maintain constant temperatures will be required. Household refrigerator-freezer combinations are generally not suitable for critical frozen storage since they must get above the freezing point temperature to self-defrost. While most freezer compartments of refrigerator-freezers will maintain -15C (except for the self-defrost cycle), many vaccines and quality control materials require frozen storage at -20C or colder, which a household refrigerator-freezer will NOT maintain reliably.
When frozen storage is required at -20C or below, a freezer designed to maintain extra-cold temperatures will be required. There are some under-counter models which are relatively inexpensive and require much less floor space than upright freezers or chest freezers. If a household freezer is purchased for reagent, quality control, or vaccine storage, a chest freezer is recommended because the cold air does not fall out of the unit when the door is opened and thus the temperature is more stable.
What about small dormitory refrigerators?
Small dorm refrigerators may be used when temperature stability is not a critical issue, but be aware that they do not maintain constant temperatures nearly as reliably as larger refrigerators or refrigerator/freezer units. These are great for any beverages you keep specifically for patients or for cold packs for injuries or injections.
How should I monitor the temperature of the refrigerator or freezer?
If refrigerated or frozen storage is required by a manufacturer, staff members should monitor and document the temperature of the refrigerator and/or freezer on a daily basis. If the monitored temperature is outside the range provided by the manufacturer, corrective action must be taken and documented to remedy the problem.
For refrigerators and freezers, thermometers suspended in a liquid solution are preferable to one that measures the temperature through the air in the unit since they do not react immediately to the opening of the door or temporary removal of the thermometer to be read. The thermometer used should be either National Institutes of Science and Technology (NIST) certified or NIST traceable. The laboratory or med-surg vendor can assist with selection of a reliable and acceptable thermometer.
Remember that state-supplied vaccine programs as well as accreditation agencies such as Commission on Office Laboratory Accreditation (COLA), Clinical Laboratory Improvement Amendment (CLIA) and Joint Commission on Accreditation of Healthcare Organizations (JCAHO) require cooling/freezing documentation. Many vaccines and medications are also extremely expensive, so it behooves the practice to protect that investment. A sample form to document temperatures is available here.
What if the power goes out?
Transfer the materials to a refrigerator that is operable, if possible, or keep everything in coolers with ice packs. For frozen materials, especially medications, it is imperative that the frozen state be maintained to preserve the integrity of the materials. Long term power outages (e.g. hurricanes or major winter storms) are a real problem. If that is common in the practice’s area, it would be worth the money to purchase a generator.
Could the power go out without me knowing it and the contents be compromised?
Yes, the penny method is to sit a penny on top of an ice cube or small container that you’ve frozen water in. If the power is out long enough for the contents of your freezer to thaw, the ice cube will melt. This will cause the penny to drop to the bottom of the ice cube tray – so check the position of the penny daily. If everything has refrozen but the penny is at the bottom of the ice cube, then everything probably thawed to an extent where it is now unsafe to use.
What is the rule about storing medical supplies, medication or vaccines in a refrigerator or freezer with drinks or food?
Don’t do it. Ever.
