INTRODUCTION
Staffing shortages have impacted clinical laboratories for decades, threatening the laboratory’s
capability of delivering timely and accurate results and putting the quality of patient care at risk.
The current staffing crisis in laboratories has been caused by a multitude of factors, including the
changing laboratory environment, the failure of the Clinical Laboratory Improvement Amendments
(CLIA) personnel standards to appropriately delineate the technical complexity of testing, and the
expansion of automation. The purpose of this document is to describe the scope and causes of
the current staffing crisis in clinical labs and suggest potential near and long-term solutions for the
association.
POLICY OPTIONS
- Advocate for and demonstrate the value of laboratory medicine by reinforcing the importance
of laboratory professionals. Recruitment efforts should be in a diverse, equitable, and inclusive
manner.
- Expand activities that engage and enhance the visibility of medical laboratory scientists (MLS)
including an enhanced platform at the annual scientific meeting and increased seminar/webinar
opportunities that help laboratory scientists advance their careers.
- Promote reclassification of laboratory tests based on performance complexity, moving tests
currently designated as high complexity testing but with lower analytical requirements into the
moderate complexity testing category and applying the existing personnel requirements.
- Promote changes to the CLIA complexity model that recognize the unique skills and value of
MLS. One option is to make the education, training, and experience requirements of an MLS
the threshold for performing high complexity tests.
- Develop educational programs that provide alternate career entry points into laboratory
medicine for non-laboratorians, while also developing a separate track for MLS seeking
professional growth and advancing within the laboratory and broader healthcare community.
SCOPE OF THE LAB STAFFING CRISIS
Staffing shortages have been reported by clinical laboratories for at least 30 years and the problem
continues to be a threat to laboratory testing (1,2). A 2018 survey performed by the American
Society for Clinical Pathology (ASCP) identified average vacancy rates of 7 – 11% in clinical
laboratories, which were as high as 25% in some areas (3). According to the United States (US)
Bureau of Labor Statistics (BLS), there were 335,500 technologist and technician positions in 2020.
This number is projected to increase by 11% to 372,000 by 2030 (4). Similarly, the US Department
of Health and Human Services (HHS), Health Resources and Service Administration (HRSA), projects
an increase in demand/growth for medical and clinical laboratory technologists and technicians of
22% between 2012 and 2025 (5). Together, these surveys indicate an insufficient number of newly
trained technologists entering the field, particularly as previous generations of laboratorians are
retiring at historic rates.
Definitions for Lab Staffing Personnel and Education
CLIA established minimum personnel testing requirements for individuals performing moderate and
high complexity testing (6). While there are several routes for meeting these minimum requirements,
laboratories traditionally hire, because of their education and training, individuals with a bachelor’s
degree (MLS) or an associate’s degree (Medical Laboratory Technician, MLT) from an accredited
institution and certification (1). In the absence of such individuals, laboratories may hire individuals
with a bachelor’s degree in biology, chemistry, or comparable program, and then provide on-the-job
training that permits them to meet the testing personnel requirements under CLIA.
While the BLS predicts the need for more individuals to perform laboratory testing, the number
of MLS and MLT accreditation programs is declining, resulting in fewer graduates. In 1983
approximately 9,000 individuals graduated from accredited and approved training programs (7).
By 1992, this number dropped by approximately 30% to 5,760, reflecting the decline in accredited
educational programs. The National Accrediting Agency for Clinical Laboratory Sciences (NAACLS)
identified a reduction of training programs from 659 programs in 1992 to 468 programs in 2002. In
2020 there were 235 MLS programs and 248 MLT programs, a decline of about 7% from 2000 (8).
REASONS FOR THE SHORTAGES
Aging Workforce
The aging workforce has severely impacted clinical laboratories; many of the experienced
professionals who had delayed retirement are now retiring or are planning to retire in the next five
years. The COVID-19 crisis further increased motivation for many staff to retire. The results of the
2020 ASCP vacancy survey demonstrated an average 5-year retirement rate of 12.3%. While the
5-year retirement rates have decreased since their peak in 2016-2018 (9), the rate of decline still
outpaces annual growth.
Salary
There is disparity in pay for laboratory staff relative to peers with similar training in other areas
of healthcare. A 2019 salary survey by ASCP reported that the average annual pay for an MLT
was $50,304.78 and for an MLS was $68,848.18 (10). An important caveat is that a third of the
respondents were from NY and California, states with typically higher pay. Nonetheless, the median
salaries stated in the ASCP survey are comparable to data from the Bureau of Labor Statistics that
state an annual wage of $57,800 nationally (4). In contrast, a registered nurse with a bachelor’s
degree in nursing has a median pay of $77,600 (11). The disparity in pay may be secondary to
laboratorian’s perceived status within the field of medicine. Laboratory medicine is traditionally non3
|
patient facing, often forcing its professionals to the fringes within medical teams. This may be in part
what also drives disparate salaries between laboratory professionals and more visible professions
such as nursing.
Growth Opportunities and Retention
Although laboratory medicine is a vital component of today’s healthcare system, the clinical
laboratory profession provides limited career growth opportunities for its workforce. The profession
has a limited career ladder within a laboratory, with advancement primarily associated with nontesting
responsibilities, such as laboratory information system, point of care, or quality management.
Like many in the health care industry, laboratorians are subject to a rigid work schedule that includes
weekends and holidays coupled with the demands of overtime hours due to high vacancy rates.
The stress from high vacancy rates, overtime, and limited advancement opportunities likely leads to
greater dissatisfaction and increased burnout.
Increased Volume of Testing and Expanding Responsibilities
Despite a stagnant workforce, clinical laboratories have continued to grow in both the volume of
testing performed and the test menus offered (12). Most clinical laboratories perform high volume
testing with estimates ranging in the tens-of-billions of laboratory tests performed in the US per
year (12–14). This volume will only increase, due in part to the aging population and an increase in
chronic disease (15). Adding to this workload is the expansion of available laboratory tests. There
has been a dramatic rise in rapid molecular testing, sequencing, and esoteric testing (16–18). 44% of
respondents on a 2018 survey stated that an increase in molecular testing has caused the greatest
change to staffing needs (3). Expansion of laboratory testing into new domains will further stretch
an already
thin workforce.
IMPACT OF THE COVID-19 PANDEMIC ON STAFFING
Even before COVID-19 emerged, observers had highlighted how the profession’s lack of
appreciation and visibility had hampered retention and recruitment efforts and limited the
availability of training programs. Non-competitive salaries has made this situation worse, possibly
hindering the ability of the laboratory community to respond during a disaster or crisis (19,20). The
COVID-19 pandemic demonstrated those concerns and further exacerbated the underlying issues at
a time when laboratories required an incredible expansion of molecular diagnostic instrumentation
and testing capabilities (21). Consistent with this, the 2020 ASCP Vacancy Survey reported the
pandemic significantly disrupted staffing and further reduced the stream of incoming graduates (9).
While few peer reviewed manuscripts provide information on how hospitals and laboratories
prioritized work throughout the COVID-19 pandemic, several articles and interviews with healthcare
and laboratory professionals have highlighted that the need to provide COVID-19 testing resulted in
the de-prioritization of other laboratory testing (22,23).
THE IMPACT OF THE STAFFING CRISIS ON PATIENT RESULTS AND TURNAROUND TIME
Impact on turnaround time
The impact of insufficient lab personnel on turnaround time can be described using basic operations
management. With a set turnaround time for a given test, the number of samples coming into
the laboratory must be balanced by the testing throughput. The throughput of the laboratory is
related to many aspects of its workflow including sufficient staffing available to perform testing.
Importantly, turnaround time is closely related to the variability in laboratory workflow and can arise
in numerous forms. For example, an increase in patients will result in an increase in samples sent
to the laboratory. Similarly, unexpected staff shortages due to sickness can result in a higher than
anticipated sample number for the staff reporting to the laboratory.
The mechanism by which many organizations continue to meet turnaround time despite staffing
shortages is by artificially increasing throughput using overtime, reduction in non-essential tasks,
and resource reallocation. As a result, burnout features prominently in many laboratories. A 2014
article from the United Kingdom reported > 50% of all laboratories were using inappropriate
staff to fill gaps in the workforce due to low wages and poor career advancement opportunities
(24). Further, 90% of reporting laboratories were severely understaffed and 60% regularly used
unqualified workers to complete daily tasks. Of note, unrealistic targets and turnaround times were
cited as contributing to the overall challenges and job-related stress of staff. Another unintended
consequence of reduced staffing is that many laboratories have limited their scope to essentially
rapid response labs; triaging tests that are less urgent to reference laboratories (25).
OTHER CONSIDERATIONS: AUTOMATION AND THE CHANGING ROLE OF
THE TECHNOLOGIST
When CLIA was initially written, computers were uncommon in clinical laboratories, total lab
automation in chemistry and microbiology had not been introduced to the market, the human
genome had not yet been sequenced, and the PCR was in its infancy. Today, use of automation,
advanced middleware-based rules, and point-of-care (POC) testing has increased astronomically
and is heavily relied upon by laboratories to increase throughput and maximize efficiencies,
particularly in the wake of a staffing shortage. Despite these dramatic changes to how laboratory
testing is performed, little has changed with regards to CLIA requirements for personnel performing
moderate complexity and high complexity laboratory testing.
Enhanced automation
One of the most robust changes to laboratory testing has been the implementation of automation.
This includes automation of the pre-analytic, analytic, and post-analytic steps of the testing
process. These considerable improvements reduce diagnostic error (26). The introduction of fully
enclosed, “Smart Instrumentation” has further improved this process. These instruments manage
and automatically perform functions such as QC, maintenance, and calibration verification. Many of
these instruments dramatically reduce the likelihood of analytical error, even relative to high volume
clinical analyzers.
The FDA categorizes non-waived tests and instruments under CLIA as moderate or highly complex
using a points based system (27). In short, this strategy determines complexity/risk based on:
- the knowledge, training and experience required of the person performing the test;
- the circumstances surrounding the use of reagents (i.e., is special handling required);
- operational steps required to perform the test;
- the availability of calibration/ QC material;
- required maintenance; and
- the complexity of interpreting the results.
While this framework is helpful, it may overestimate the potential risk to a patient and unnecessarily
place testing in the high complexity category. Examples of such tests include tests:
- that are designated as high complexity because they require a calculation not performed by
the instrument (although may be automatable using middleware systems (28);
- those that are manual methods but relatively simple to perform such as an ELISA (29); and
- a fully assays in which inaccurate results may cause excess risk to patients despite ease of use
of the method itself and the need for special controls (30).
- modified FDA cleared tests, which are considered as a laboratory developed test, although
the modification does not affect the clinical claim of the manufacturer.
In these instances, the current test designations do not truly consider the ease or difficulty of
performing testing, potentially limiting the staff able to perform testing under the current structure
of CLIA.
Considerations with the middleware and rules base approach
Use of middleware helps ensure accuracy of test results by creating rules for acceptance before
a result can be reported. If the results do not meet the required rules, they must be reviewed by
staff that have the required experience to review/troubleshoot and determine which further actions
need to be taken before the results are accepted or rejected. An example of a rule that helps
ensure test quality is a “delta check,” which compares the feasibility of a current patient result
relative to a previous result in the laboratory information system (32). Robust and accurate rules
built in a laboratory information system reduces the likelihood of laboratory error and thus risk to a
patient (33). However, the use of advanced rules and the reduced likelihood of error has not been
addressed by CLIA with regards to testing personnel.
Considerations for point of care testing
Point of care testing is commonly used in hospitalized and ambulatory patients to provide rapid
treatment decisions with the goal of improving patient care. The emergence of simple, sample-toanswer
“Smart Instrumentation” has led to extraordinary growth in point of care testing. Despite
changes in the frequency and landscape of laboratory testing performed at the point of care, there
have been limited changes made under CLIA regarding testing at near patient settings. This may
have helped drive the desire for the Center for Medicaid Services (CMS) to recommend nursing to
perform high complexity testing; a recommendation that was met with resistance in the laboratory
community (34). Nonetheless, the requirements for testing at near-patient locations remain
antiquated relative to the novel instrumentation used.
RECOMMENDATIONS FROM OTHER PROFESSIONAL SOCIETIES
Given the widespread shortages, numerous task forces and documents have been published to
attempt to address the shortages.
A 2021 report by the ASCP interviewed numerous laboratory professionals and came up with the
following recommendations. 1) improve the visibility of clinical laboratory occupations (i.e., free
tuition, offer incentives for community outreach, promote consistent titles), 2) Improving workforce
recruitment and retention, 3) focus on diversity and inclusion (35).
The ASCLS 2020 position statement (36) calls for a multi-pronged approach including 1) a
congressional study to identify the nature of the workforce shortage and impact on the healthcare
system 2) that federal funds are provided to increase the number of clinical laboratory scientists
through Title VII expansion, 3) that STEM (Science Technology Engineering Mathematics)
programming include laboratory science, 4) training sites should be published via electronic
6 |
clearinghouse, 5) that retention is provided by making laboratorians an integral part of the care
team and providing an improved career latter.
Other experts in the field have made recommendations for ways to circumvent the staffing
shortage. In Canada, the Using Labs Wisely program has been implemented in the wake of the
COVID-19 pandemic to reduce unnecessary testing with the secondary goal of removing excess
burden from the laboratory (37). The nursing field has addressed shortages by engaging key
stakeholders including manufacturers, states, and private institutions to provide increased funding
for scholarships, add more programs, and increase the national reputation of the profession (38).
McKinsey, a consulting agency, recently made strong recommendations that address the mental
health and preferences of today’s nurses that also are applicable to laboratory professionals (39).
RECOMMENDATIONS AND CONSIDERATIONS FOR AACC
AACC’s mission is to provide global leadership in advancing the practice and profession of clinical
laboratory science and medicine. AACC has a broad international reach, a diverse membership
(medical technologists, laboratory supervisors, laboratory directors, and industry partners)
and a considerable record of advocacy for the laboratory community. Given this, the below
recommendations reflect potential novel methods to address the staffing shortage that involves all
aspects of AACC membership. The recommendations build upon the strategic plan of AACC.
