Clinicians rely on the laboratory to provide accurate and reliable test results in order to treat the patient appropriately. Accurate patient identification is the first critical step to providing the right health care treatment for every patient. The consequences of an identification error can significantly impact an individual’s future health. In laboratory medicine, strict adherence to patient identification and specimen labeling requirements is necessary to maintain the unequivocal link between the accurately identified patient and the specimen throughout the path-of-workflow.

Proficiency testing (PT) is a valuable tool in the quality improvement process. PT provides one measure of objective evidence of laboratory competence to customers and regulatory and accreditation organizations. It serves as a unique source of information not obtainable by other methods. Current accreditation requirements include integration of PT into the laboratory’s quality improvement program.

Nonconforming events in the laboratory can be reduced by implementing an effective quality management system (QMS). A laboratory QMS is a systematic, integrated set of activities to establish and control the work processes from preanalytical through postanalytical processes, manage resources, conduct evaluations, and make continual improvements to ensure consistent quality results.1 All aspects of the laboratory operation need to be included in a QMS.

Infections due to methicillin-sensitive Staphylococcus aureus (MSSA) continue to be a significant source of morbidity and mortality. While antistaphylococcal penicillins, such as nafcillin, have been the mainstay of therapy for MSSA, the use of cefazolin has grown increasingly popular. Indeed, recent data from observational clinical studies suggest that cefazolin is as efficacious as nafcillin, with less toxicity, has a more favorable dosing schedule, and possibly improves survival. Thus, cefazolin has become first line therapy for the treatment of MSSA infections.
