Practice Model Trends in Medicare Payments Across States and Regions.

Anesthesia delivery models have long been shaped by workforce trends, state and federal regulations, economic incentives driven by reimbursement, and the normative preferences of provider and facility organizations. In recent years, there has been a significant shift toward greater use of more efficient certified registered nurse anesthetist (CRNA)-oriented delivery models observed at the national level Medicare data. However, given the wide range of these factors across states and regions, this shift has likely occurred at an uneven pace. This study analyzes the influence of provider workforce composition and CRNA scope of practice (SOP) regulations on usage of competing types of anesthesia delivery models, including anesthesiologist alone, care team, and undirected CRNA models. Results show that over the period from 2010-2019, anesthesia delivery models utilized under Medicare Part B have become increasingly oriented around the use of CRNAs. However, increases in the care team vs undirected CRNA model are highly uneven and inconsistent across states, even after adjusting for workforce and SOP. Speculation on additional normative or organization-driven reasons for persistent use of inefficient delivery models in some places is offered.

From the Operating Room to the Front Lines: Shared Experiences of Nurse Anesthetists During the Coronavirus Pandemic.

Coronavirus disease 2019 (COVID-19) has resulted in severe health, economic, social, political, and cultural consequences while thrusting Certified Registered Nurse Anesthetists (CRNAs) at the forefront of battling an often invisible enemy. A mixed-methods study was conducted to assess the impact of the COVID-19 pandemic on CRNA practice. The purpose of the qualitative component of the study, a focused ethnography, was to use personal and group interviews to determine the shared experiences of CRNAs who worked during the COVID-19 pandemic. Six themes were identified: (1) CRNAs are part of the solution, (2) doing whatever it takes, (3) CRNAs are valued contributors, (4) removal of barriers promotes positive change, (5) trying times, and (6) expertise revealed. The quantitative component of the study will be discussed in a separate article.

Work patterns, socio-demographic characteristics and job satisfaction of the CRNA workforce - Findings from the 2019 AANA survey of CRNAs.

BACKGROUND: An ongoing shortage of anesthesia providers lends importance to the study of job satisfaction and retention among this critical workforce. Certified registered nurse anesthetists (CRNA) make up an increasing share of this workforce and the impact of factors affecting their satisfaction is not fully understood. PURPOSE: Understanding the job satisfaction of Certified Registered Nurse Anesthetists (CRNA) and its determinants. Methods We conduct a comprehensive survey in which we collect information on the job satisfaction of a nationally representative sample of CRNAs, along with information on factors related to their job satisfaction. We measure the impact of these characteristics on the CRNA's level of job satisfaction using a multivariate regression analysis. FINDINGS: Many CRNAs would prefer to pursue training opportunities on peripheral nerve blocks, epidural anesthesia and advanced airway management. Refreshing training on these procedures are factors that may enhance their job satisfaction, and potentially reduce unmet needs for anesthesia services. DISCUSSION: We find that most CRNAs are either very satisfied or somewhat satisfied with their job. Factors that significantly increase the probability of being very satisfied include greater autonomy in the delivery of anesthesia, and higher compensation.

Considerations for an aging nurse anesthetists workforce.

The Certified Registered Nurse Anesthetists (CRNA) workforce is aging. It is estimated that nearly half (49.7%) of the CRNA workforce is age 50 or greater, with those practicing in management positions and as educators having the oldest mean ages. Older CRNAs face workplace challenges that can lead to decreased productivity and overall job satisfaction. Common injuries to older practitioners result from repetitive motion, slips and falls, needle sticks, fatigue, and emotional or mental health related illness. Because of the high acuity environment in which CRNAs practice they are at an elevated risk for these injuries. Creating a healthy and supportive work environment has been shown to improve the retention of aging healthcare workers, and succession planning is essential in preparing for their retirement.

Cardiovascular Complications in Patients Undergoing Noncardiac Surgery: A Cardiac Closed Claims Thematic Analysis.

More than 200 million adults have noncardiac surgery worldwide every year. Anesthesia closed claims databases allow anesthesia providers to critically examine adverse outcomes that occur during an anesthetic or immediately following the administration of anesthesia, to aid in improving patient care. A qualitative analysis of 34 closed malpractice claims with a cardiac-related event was conducted to determine common themes. Five common themes emerged: preanesthetic evaluation, normalization of deviance, medications, hemorrhage, and knowledge deficit/failed clinical reasoning.

Advocacy, Research, and Anesthesia Practice Models: Key Studies of Safety and Cost-Effectiveness.

The practice of anesthesia includes multiple competing practice models, including services delivered by anesthesiologists, independent practice by certified registered nurse anesthetists (CRNAs), and team-based approaches incorporating anesthesiologist supervision or direction of CRNAs. Despite data demonstrating very low risk of death and complications associated with anesthesia, debate among professional societies and policymakers persists over the superiority or equivalence among these models. The American Society of Anesthesiologists uses published findings as evidence for claims that anesthesia is safer when anesthesiologists lead in providing care. The American Association of Nurse Anesthetists cites its own research on safety and cost-efficiency outcomes to defend against these claims. We review and critique studies of the safety outcomes and cost-effectiveness of anesthesia delivery that have been cited in the Federal Trade Commission comment letters related to competition in health care, where each profession has laid out their case for how they ought to be recognized in the market for anesthesia services. The Federal Trade Commission has a role in protecting consumers from anticompetitive conduct that has the potential to impact quality and cost in health care. Thus, it is important to evaluate the evidence used to make claims about these topics. We argue that while research in this area is imperfect, the strong safety record of anesthesia in general and CRNAs in particular suggest that politics and professional interests are the main drivers of supervision policy in anesthesia delivery.

Preventable Closed Claims in the AANA Foundation Closed Malpractice Claims Database.

Medical errors are among the top 3 causes of patient deaths in the United States, with up to 400,000 preventable deaths occurring in hospitalized patients each year. Although improvements have been made in anesthesia patient safety, adverse outcomes continue to occur. This study used thematic analysis to examine anesthesia closed claims that were associated with preventable morbidity and mortality. Investigators determined that 123 closed malpractice claims files from the American Association of Nurse Anesthetists (AANA) Foundation closed claims database involved events that the involved Certified Registered Nurse Anesthetist could have prevented. Factors that were associated with preventable closed claims included communication failures, violations of the AANA Standards for Nurse Anesthesia Practice, and errors in judgment.

Improving Patient Outcomes Through Closed-Claims Analysis: Salient Characteristics and Patterns Associated With Respiratory Events.

A retrospective, exploratory research design was used to analyze salient characteristics and patterns associated with closed claims involving Certified Registered Nurse Anesthetists (CRNAs) in which a respiratory event caused the adverse outcome. Alleged malpractice acts found in these claims occurred between 2003 and 2012. Respiratory events were the most frequent cause of adverse outcomes in the current database (34%). The respiratory adverse outcomes often resulted in mortality or significant and permanent morbidity (69%) and were largely preventable (81%). Of these respiratory outcomes, inadequate ventilation and oxygenation associated with respiratory depressant medications accounted for 37% of the adverse outcomes (hypoventilation = 27.4%; respiratory arrest = 9.5%). In every hypoventilation claim, regardless of the type of anesthetic technique, a failure to optimally monitor the patient's ventilation was identified as a sentinel, contributory practice pattern. Payouts for CRNAs were made in 55% of respiratory claims and averaged $282,840. Claims judged to have an AANA standard-of-practice guideline violation that directly contributed to the adverse outcome were more likely to result in a payout vs those involving no violation (P <.01). Costs to defend against the malpractice allegation for all respiratory event claims averaged $51,996 (SD = $52,658) and ranged from $525 to $227,153.

A Content and Thematic Analysis of Closed Claims Resulting in Death.

The analyses of malpractice closed claims conducted by the AANA Foundation Closed Claims Research Team are scientific studies of adverse anesthetic events where a Certified Registered Nurse Anesthetist was identified as potentially contributing to the outcome. From July 2013 to March 2014, the AANA Foundation Closed Claims Researchers evaluated 245 closed claims from the CNA Insurance Companies spanning from 2003 to 2012. An adverse event leading to death occurred in 87 of the claims. This article describes the use of content and thematic analysis in the evaluation of these closed claims. The purpose of the study was to establish themes that would provide unique insights into the events leading up to death with a focus on the role anesthesia may or may not have had in the outcome. Major themes identified include: (1) patient factors, (2) provider factors, (3) environmental factors, and (4) team/group factors.

Developing a Health Services Research Agenda in Nurse Anesthesia Using a Modified Delphi Method.

The authors sought to formalize a process and ascertain research priorities for nurse anesthesia, which resulted in a new Health Services Research (HSR) Agenda. After formation of an 8-member ad hoc committee (representing different stakeholders from the American Association of Nurse Anesthetists [AANA]), a modified Delphi technique was used to determine the top 3 HSR research priorities for the 2016 fiscal year. The committee identified 24 high-priority HSR questions/topics specific to policy, education, or practice. An anonymous, web-based survey was distributed to the committee to rank and prioritize the 24 identified research questions using a 5-point Likert scale. Two consensus meetings and a second anonymous, web-based survey were conducted to prioritize the top 3 HSR questions. Through this systematic method, an HSR agenda was created based on the research questions initially submitted by the committee. The method used ensured that the new research agenda is relevant and reflects the priorities of Certified Registered Nurse Anesthetists. This agenda was incorporated into the updated AANA and AANA Foundation Joint Research Program as suggested areas of research. This agenda is intended to focus investigators and funding organizations on highest priority areas in nurse anesthesia research.

Geographical Imbalance of Anesthesia Providers and its Impact On the Uninsured and Vulnerable Populations.

The purpose of this study was to determine if there is a relationship between socioeconomic factors related to geography and insurance type and the distribution of anesthesia provider type. Using the 2012 Area Resource File, the correlation analyses illustrates county median income is a key factor in distinguishing anesthesia provider distribution. Certified registered nurse anesthetists (CRNAs) correlated with lower-income populations where anesthesiologists correlated with higher-income populations. Furthermore, CRNAs correlated more with vulnerable populations such as the Medicaid-eligible population, uninsured population, and the unemployed. Access to health care is multifactorial; however, assuring the population has adequate insurance is one of the hallmark achievements of the Affordable Care Act. Removing barriers to CRNA scope of practice to maximize CRNA services will facilitate meeting the demand by vulnerable populations after full implementation of the Affordable Care Act.

The AANA Foundation Malpractice Closed Claims Study: A Descriptive Analysis.

The AANA Foundation Closed Claims Researchers evaluated 245 closed claims spanning from 2003-2012. The majority of claims comprised CRNA providers whom are mainly male, independent contractors, certified between 1980-1999, and with malpractice coverage limits of $1 million/$3 million. The median age for all claimants was 50 years old, and 63.7% of claimants were female. For those claims where race was known, 54% of claimants were Caucasian. Most adverse events occurred in a hospital with an outpatient admission status. The majority of adverse events were identified as intra-anesthesia. The top five surgical procedures associated with these claims were orthopedic general surgery, cosmetic, obstetric, and neurologic procedures. An adverse event leading to death occurred in 35.1% of claims. Regardless of severity of injury, reviewers determined that 45.5% of negative outcomes were preventable, 32.7% of the anesthesia treatment was inappropriate, and 29% of negative outcomes were caused by CRNAs' actions. Reviewers found that no AANA Standards were breached in 45.7% of claims; however, Standards 4, 5, and 3 were the most common standards breached. The most costly severity classification was major permanent injury (ie, paraplegia, blindness, loss of two limbs, or brain ddamage) with a median payment of $299,810.

Ouality and performance measurement: national efforts to improve quality of care through measurement development.

The US Department of Health and Human Services created the National Quality Strategy to provide a framework to focus providers and organizations in achieving greater impact around better care, healthy people and communites, and affordable care. Providing incentive programs around quality measurement is one mechanism used to achieve these aims. Certified Registered Nurse Anesthetists (CRNAs) should begin to familiarize themselves with the consensus development process used in measurement development and the importance of measurement endorsement through the National Quality Forum. Additionally, CRNAs should become familiar with what Physician Quality Reporting System (PORS) measures CRNAs are currently using in anesthesia and the 2015 payment adjustments one may face if not currently reporting to the PORS.

The National Practitioner Data Bank: what CRNAs need to know.

As a nationwide flagging system, the National Practitioner Data Bank (NPDB) allows state licensing boards, hospitals, and other registered healthcare entities the ability to monitor practitioners through reporting and inquiry about the qualifications and competency of healthcare practitioners seeking clinical privileges where incompetence or unprofessional conduct could adversely affect a patient's welfare. Certified Registered Nurse Anesthetists are not exempt from being reported on or queried by registered reporting and querying entities. The NPDB warehouses data pertaining to adverse actions or medical malpractice payments taken against a practitioner. Based on the updated federal ruling published in the Federal Register regarding the NPDB and Section 1921 of the Social Security Act, the NPDB has expanded the definition of healthcare practitioners to include all healthcare practitioners as a means of protecting beneficiaries of the Social Security Act's healthcare programs. As such, nurse anesthetists should be aware of the additional reportable information that may be collected or disseminated based on the updated ruling pertaining to the NPDB.

The national practitioner data bank and CRNA anesthesia-related malpractice payments.

A retrospective analysis of the National Practitioner Data Bank (NPDB) Public Use Data File was performed on anesthesia-related malpractice payments from 2004 to 2010. Anesthesia-related allegations, malpractice act or omission codes, severity of injury, and cost were assessed. The NPDB captured 369 anesthesia-related malpractice payments associated with Certified Registered Nurse Anesthetists (CRNAs), of which the 3 most frequently coded injury classifications for severity were death, minor permanent injury, and grave permanent injury. In general, the most costly payments based on median cost were major permanent injury, followed by grave permanent injury and death. When reviewing specific allegations of malpractice act or omission among the total number of CRNA malpractice payments, the most common allegations were improper performance,, failure to monitor, and problem with intubation. Patients between the ages of 40 and 59 years, inpatients, and female gender were independently more prevalent among CRNA malpractice claims leading to payment than other patient demographics.

Studies support removing CRNA supervision rule to maximize anesthesia workforce and ensure patient access to care.

Recent research reaffirms that Certified Registered Nurse Anesthetists (CRNAs) are critical to the delivery of anesthesia in the United States and argues persuasively for the removal of barriers-including supervision requirements--that prevent CRNAs and other advanced practice registered nurses (APRNs) from practicing to the full extent of their education and training. As we as a nation strive to make healthcare accessible, ever safer, and affordable, the health system must use anesthesia professionals as efficiently as possible. Repealing the federal Medicare physician supervision requirement for nurse anesthetists is an important step toward achieving this goal.

New estimates for CRNA vacancies.

A national survey to estimate vacancy rates of Certified Registered Nurse Anesthetists (CRNAs) in hospitals and ambulatory surgical centers was conducted in 2007. Poisson regression methods were used to improve the precision of the estimates. A significant increase in the estimated vacancy rate was reported for hospitals relative to an earlier study from 2002, although it is important to note that there were some methodological differences between the 2 surveys explaining part of the increase. Results from this study found the vacancy rate was higher in rural hospitals than in nonrural hospitals, and it was lower in ambulatory surgical centers. A number of simulations were run to predict the effects of relevant changes in the market for surgeries and number of CRNAs, which were compared to the predictions from the previous survey. The remarkable factor since the last survey was the unusually large rate of new CRNAs entering the market, yet the vacancy rates remain relatively high.
