Q

Duties of technologists, technicians, and specialists

A

Duties of technologists, technicians, and specialists
◦ The responsibilities of MLS and MLT laboratorians vary but may include performing some of the same laboratory assays, supervising other staff, teaching, or research.
◦ Because of in-depth knowledge of technical aspects, principles of methodology, and instrumentation used for the various laboratory assays, the laboratory professional is able to correlate and interpret the data.
◦ Although MLS and MLT may collect blood specimens or process them, phlebotomists collect blood specimens in larger hospitals.

24
Q

Goals were to ensure high quality of lab results.
CLIA requirements for personnel

A

◦ Define the responsibilities, educational requirements, training, and experience of employees performing tests of moderate or high complexity.
◦ There are no CLIA regulations for testing personnel who work at sites performing only waived tests or provider-performed microscopy testing.
◦ Requirements are more stringent for those performing tests of the highly complex category.

25
Q

Clinical Laboratory Improvement Amendments (CLIA) of 1988
Levels of general laboratory testing include waived tests, moderately complex tests, and highly complex tests.

The criteria for classification include:

A

◦ Risk of harm to the patient
◦ Risk of an erroneous result
◦ Type of testing method used
◦ Degree of independent judgment and interpretation needed ◦ Availability of the test in question for home use

26
Q

Waived tests

A

Cleared by the US Food and Drug Administration for home use
◦ Use simple methodologies unlikely to cause erroneous results and pose no reasonable risk of harm to the patient if performed incorrectly
◦ Examples: dipstick urinalysis and blood glucose

27
Q

Provider-performed microscopy (PPM)

A

◦ Must be personally performed by the practitioner (defined as a physician, a midlevel practitioner under the supervision of a physician, or a dentist)
◦ Must be categorized as moderately complex
◦ The primary instrument for performing the test is the microscope (limited to
brightfield or phase-contrast microscopy). ◦ The specimen is labile.
◦ Control materials are not available.
◦ Specimen handling is limited.

28
Q

oThe organization of a particular clinical laboratory depends on its size, the number of tests done, and the facilities available.

A

◦ Larger laboratories tend to be departmentalized; a separate area is designated for each of the various divisions. Cytogenetics, toxicology, flow cytometry, and other specialized divisions (such as molecular diagnostics) are present in larger laboratories.
oThe trend is to have a more “open” design or a core laboratory where hematology, urinalysis, hemostasis/coagulation, and clinical chemistry share work space.
oCross-training is important in a core laboratory model.

29
Q

oA working clinical laboratory is traditionally organized into several major scientific disciplines:

A

:blood banking/transfusion medicine, clinical chemistry (may include toxicology), flow cytometry, hematology and hemostasis, immunology and serology, microbiology, and urinalysis.

30
Q

oThe core laboratory configuration combines routine

A

hematology, hemostasis and blood coagulation, and clinical chemistry.

31
Q

oEach specialty department focuses on a different area of

A

laboratory medicine.

32
Q

oMany medium to large size laboratories have developed a central testing area with a cluster of instruments devoted to high volumes of test samples.

A

.
oExpanded directions of laboratory testing include molecular diagnostics, an application of biotechnology.
◦ Applies the principles of basic molecular biology to the study of human diseases
◦ Provides information related to molecular genetics research as real-time information for applications such as gene therapy, genetic screening, stem cell research, cloning, and cell culture

33
Q

Modern health care organizations have many different configurations, depending on the geographic region and market, mix of patients, overall size, and affiliations.

A

.
◦ The size of health care organizations ranges from the very large tertiary care–level teaching hospitals, to community hospitals, to freestanding specialty clinics or phlebotomy drawing stations.
◦ A common organizational structure for a hospital includes the chief executive officer and the board of trustees, who set policy and guide the organization.
◦ The chief operating officer is responsible for implementing policies and daily activities.

34
Q

oOther high-level positions can include the chief financial officer, chief information officer, and chief technology officer, depending on the size of a health care organization.

A

.
oA variable number of vice presidents (VPs) have several departments reporting to them.
oOrganizations usually have VPs of nursing, clinical services, general services, and human resources.
oThe VP of clinical services oversees the managers of the clinical laboratory as well as radiology and pharmacy.

35
Q

There are three primary laboratory accrediting organizations:

A

Commission on Office Laboratory Accreditation (COLA)
College of American Pathologists (CAP): an internationally recognized program that utilizes teams of practicing laboratory professionals as inspectors
The Joint Commission (TJC) has been evaluating and accrediting hospital laboratory services since 1979 and freestanding laboratories since 1995.
Other specialty organizations, including the American Association of Blood Banks, American Society of Histocompatibility and Immunogenetics, and American Osteopathic Association, accredit additional facilities.

46
Q

In addition to CLIA’88, other state and federal regulations regulate chemical waste disposal, use of hazardous chemicals, and issues of laboratory safety, including handling of biohazardous materials and application of Standard Precautions.

A

◦ External controls include standards mandated by public health laws and reporting requirements through the Centers for Disease @Control and Prevention (CDC) and through certification @and @licensure requirements issued by the US Food and Drug (FDA).@
◦ State regulations are imposed by Medicaid agencies, state environmental laws, and state public health laws and licensure laws.
◦ Local regulations include those determined by building codes and fire prevention codes.

Chain of custody
◦ When specimens are involved in possible medicolegal situations, certain specimen-handling policies are required.
◦ For evidence to be admissible, each step of the analysis, beginning with the moment the specimen is collected and transported to the laboratory, to the analysis itself and the reporting of the results, must be documented; this process is known as “maintaining the chain of custody.”

A

Other legal considerations
◦ Health care organizations and their employees are obliged to provide an acceptable standard of care, defined as the degree of care a reasonable person would take to prevent an injury to another.

54
