• Material management is a systematic process of overseeing and controlling the acquisition and utilization of supplies to ensure both availability and cost effectiveness.
• Material management consists of purchasing/requisitioning of supplies, oversight of the products as they arrive, and maintenance and repair.
• The material management department includes purchasing, which oversees the ordering of supplies and processing of invoices from vendors, and the stockroom, which maintains security and inventory and issues supplies.
• The goals of material management should ensure that supplies meet quality, quantity, and timeline requirements.
• The goals of material management must include steps to guarantee the material management benefits considerations and considerations.
• Material management benefits considerations include product research and product specifications, acquisition of new equipment, choice of proper instrument, purchase and installation of instruments, maintenance and repair, supply ordering process, inventory management, and financial control.
• Product research and product specifications are part of material management.
• Acquisition of new equipment is a part of material management.
• Choice of proper instrument is a part of material management.
• Purchase and installation of instruments is a part of material management.
• One control result exceeds its mean+2SD limit and the next exceeds its mean-2SD limit is cause for rejecting an analytical run.
• Areas that must be properly aligned to achieve institution’s quality performance goals include the philosophy or attitude of its people, the operational system of the enterprise, and the actual quality assessment and monitoring program in place.
• Quality management begins with how well managers incorporate quality practices into their management functions.
• The philosophy of quality reflects the attitude of the people toward their work, themselves, the organization, and their customer.
• Operational systems represent the actual practices taking place in an organization.
• Quality management programs address specific issues and goals and are plans for ensuring compliance or bringing about change.
• Proficiency testing is the most commonly employed type of external quality assessment, as it is able to address many laboratory methods.
• Proficiency testing is a method that allows for comparison of a laboratory’s testing to a source outside the laboratory.
• In quality assurance, 10 consecutive control result fall on one side of the mean is cause for rejecting an analytical run.
• Proficiency testing methods include rechecking and retesting, on-site evaluation, and proficiency testing.
• The steps in proficiency testing are: the laboratories participating in the programme analyze the samples and return their results to the central organization, results are evaluated and analyzed, and the laboratories are provided with information about their performance and how they compared with other participants.
• Variability is a normal occurrence when a control is tested repeatedly.
• Using the Westgard multirule system, describe the control values for each day in the following slide.
• The goal is to differentiate between variability due to chance from that due to error.
• Maintenance and repair are a part of material management.
• Types of Laboratory Examinations include Quantitative, Semi-Quantitative, Qualitative, and Control Materials.
• Control materials should be appropriate for the diagnostic sample, values should cover medical decision points, they should be similar to the test sample (matrix), and should be available in large quantity; ideally enough for one year.
• Semi-Quantitative examinations measure both the quantity and quality of a particular substance in a sample, with results expressed as an estimate of the measured substance.
• Qualitative examinations do not measure the quantity or quality of a particular substance in a sample, but instead identify the presence or absence of a substance.
• The result of any laboratory examination is only as good as the sample received in the laboratory.
• Each sample should be labeled with the patient’s name, patient’s unique ID number, test ordered, time and date of collection, and collector’s initials.
• Control Materials are substances used to validate the reliability of the test system.
• Improper collection can lead to delays in reporting test results, unnecessary re-draws/re-tests, decreased customer satisfaction, increased costs, and more.
• Controls are substances similar to patients’ samples that have an established concentration, used to ensure the procedure is working properly.
• Quantitative examinations measure the quantity of a particular substance in a sample, with results expressed as an estimate of the measured substance.
• Control materials should be stored correctly.
• Calibrators are substances with a specific concentration used to set (calibrate) the measuring points on a scale.
• In-house pooled sera are used for full assays.
• The laboratory’s responsibilities include patient preparation, patient identification, type of sample required, type of container needed, labeling, special handling, and safety precautions.
• Supply ordering process is a part of material management.
