Disparities in care, public health and the role of the anesthesiologist

Anesthesiologists and Community Engagement: A Scoping Review of the Literature

Millions of individuals require anesthesia services each year. Although anesthesia-associated mortality rates have declined, anesthetic-related morbidity remains high, particularly among vulnerable populations. Disparities in perioperative screening, optimization, surveillance, and follow-up contribute to worse outcomes in these populations. Community-engaged collaborations may be the essential ingredient needed for anesthesiologists to improve disparities in anesthetic outcomes and prioritize the needs of patients and communities. This scoping review seeks to examine the available literature on community engagement among anesthesiologists to identify gaps and seek opportunities for future work. This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). OVID MEDLINE, Scopus, and Web of Science Core Collection were searched to identify sources that used or recognized community-engaged strategies and involved the work of anesthesiologists. Sources were selected based on inclusion criteria and consistent data were extracted from each paper for compilation in a data chart. The initial search generated 1230 articles of which 16 met criteria for inclusion in the review. An updated search of the literature and reference scan of included sources resulted in 7 additional articles being included. The sources were grouped according to overarching themes and methods used and ultimately categorized according to the spectrum of public participation developed by the International Association for Public Participation (IAP2). This spectrum includes 5 levels: inform, consult, involve, collaborate, and empower. This review identified 5 sources at the inform level, 8 studies in consult, 0 in involve, 7 in collaborate, and 3 in empower. Results indicate that most initiatives representing deeper levels of community engagement, at the collaborate or empower level, occur internationally. Efforts that occur in the United States tend to emphasize engagement of individual patients rather than communities. There is a need to pursue deeper, more meaningful community-engaged efforts within the field of anesthesiology at a local and national level.

Racial and Ethnic Disparities in Delivery In-Hospital Mortality or Maternal End-Organ Injury: A Multistate Analysis, 2007-2020

Background: In the United States, Black maternal mortality is 2-4 × higher than that of White maternal mortality, with differences also present in severe maternal morbidity and other measures. However, limited research has comprehensively studied multilevel social determinants of health, and their confounding and effect modification on obstetrical outcomes. Materials and Methods: We performed a retrospective multistate analysis of adult inpatient delivery hospitalizations (Florida, Kentucky, Maryland, New Jersey, New York, North Carolina, and Washington) between 2007 and 2020. Multilevel multivariable models were used to test the confounder-adjusted association for race/ethnicity and the binary outcomes (1) in-hospital mortality or maternal end-organ injury and (2) in-hospital mortality only. Stratified analyses were performed to test effect modification. Results: The confounder-adjusted odds ratio showed that Black (1.33, 95% confidence interval [CI]: 1.30-1.36) and Hispanic (1.14, 95% CI: 1.11-1.18) as compared with White patients were more likely to die in-hospital or experience maternal end-organ injury. For Black and Hispanic patients, stratified analysis showed that findings remained significant in almost all homogeneous strata. After statistical adjustment, Black as compared with White patients were more likely to die in-hospital (1.49, 95% CI: 1.21-1.82). Conclusions: Black and Hispanic patients had higher adjusted odds of in-patient mortality and end-organ damage after birth than White patients. Race and ethnicity serve as strong predictors of health care inequality, and differences in outcomes may reflect broader structural racism and individual implicit bias. Proposed solutions require immense and multifaceted active efforts to restructure how obstetrical care is provided on the societal, hospital, and patient level.

Hospital safety-net burden is associated with increased inpatient mortality after elective total knee arthroplasty: a retrospective multistate review, 2007-2018

BACKGROUND

Total knee arthroplasty (TKA) is among the most common surgical procedures performed in the USA and comprises an outsized proportion of Medicare expenditures. Previous work-associated higher safety-net burden hospitals with increased morbidity and in-hospital mortality following total hip arthroplasty. Here, we examine the association of safety-net burden on postoperative outcomes after TKA.

METHODS

We retrospectively analyzed 1 141 587 patients aged ≥18 years undergoing isolated elective TKA using data from the State Inpatient Databases for Florida, Kentucky, Maryland, New York and Washington from 2007 through 2018. Hospitals were grouped into tertiles by safety-net burden status, defined by the proportion of inpatient cases billed to Medicaid or unpaid (low: 0%-16.83%, medium: 16.84%-30.45%, high: ≥30.45%). Using generalized estimating equation models, we assessed the association of hospital safety-net burden status on in-hospital mortality, patient complications and length of stay (LOS). We also analyzed outcomes by anesthesia type in New York State (NYS), the only state with this data.

RESULTS

Most TKA procedures were performed at medium safety-net burden hospitals (n=6 16 915, 54%), while high-burden hospitals performed the fewest (n=2 04 784, 17.9%). Overall in-patient mortality was low (0.056%), however, patients undergoing TKA at medium-burden hospitals were 40% more likely to die when compared with patients at low-burden hospitals (low: 0.043% vs medium: 0.061%, adjusted OR (aOR): 1.40, 95% CI 1.09 to 1.79, p=0.008). Patients who underwent TKA at medium or high safety-net burden hospitals were more likely to experience intraoperative complications (low: 0.2% vs medium: 0.3%, aOR: 1.94, 95% CI 1.34 to 2.83, p<0.001; low: 0.2% vs high: 0.4%, aOR: 1.91, 95% CI 1.35 to 2.72, p<0.001). There were no statistically significant differences in other postoperative complications or LOS between the different safety-net levels. In NYS, TKA performed at high safety-net burden hospitals was more likely to use general rather than regional anesthesia (low: 26.7% vs high: 59.5%, aOR: 4.04, 95% CI 1.05 to 15.5, p=0.042).

CONCLUSIONS

Patients undergoing TKA at higher safety-net burden hospitals are associated with higher odds of in-patient mortality than those at low safety-net burden hospitals. The source of this mortality differential is unknown but could be related to the increased risk of intraoperative complications at higher burden centers.
