Effects of glucagon-like peptide-1 receptor agonists on gastric mucosal visibility and retained gastric contents during EGD.

BACKGROUND AND AIMS: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are increasingly used in diabetes and obesity management. Although GLP-1RAs delay gastric emptying, their impact on visibility during EGD remains uncertain. METHODS: A 1:1 matched case-control study was conducted. Individuals undergoing EGD who were taking GLP-1RAs were matched to nonusers based on demographic characteristics and diabetes status. A validated scale (POLPREP) was used to determine gastric mucosal visibility scores. RESULTS: A total of 84 pairs (N = 168) were included. GLP-1RA users had significantly lower visibility scores, with a 2.42 times higher likelihood of lower scores compared with nonusers. In addition, GLP-1RA users had a higher incidence of retained gastric contents (13.1% vs 4.8%; adjusted odds ratio, 4.62; P = .025) and aborted procedures due to this issue. No anesthesia-related adverse events were observed. CONCLUSIONS: GLP-1RA use at the time of endoscopy exhibited higher odds of lower gastric mucosal visibility scores, retained contents, and aborted procedures. Further research is warranted.

Patient selection for nonoperating room anesthesia.

PURPOSE OF REVIEW: Given the rapid growth of nonoperating room anesthesia (NORA) in recent years, it is essential to review its unique challenges as well as strategies for patient selection and care optimization. RECENT FINDINGS: Recent investigations have uncovered an increasing prevalence of older and higher ASA physical status patients in NORA settings. Although closed claim data regarding patient injury demonstrate a lower proportion of NORA cases resulting in a claim than traditional operating room cases, NORA cases have an increased risk of claim for death. Challenges within NORA include site-specific differences, limitations in ergonomic design, and increased stress among anesthesia providers. Several authors have thus proposed strategies focusing on standardizing processes, site-specific protocols, and ergonomic improvements to mitigate risks. SUMMARY: Considering the unique challenges of NORA settings, meticulous patient selection, risk stratification, and preoperative optimization are crucial. Embracing data-driven strategies and leveraging technological innovations (such as artificial intelligence) is imperative to refine quality control methods in targeted areas. Collaborative efforts led by anesthesia providers will ensure personalized, well tolerated, and improved patient outcomes across all phases of NORA care.

Non-operating room anesthesia workflow (NORA) implementation to improve start times in interventional radiology.

BACKGROUND: Non-OR Anesthesia (NORA) is rapidly becoming standard in many high-volume institutions and efficiency in these spaces has yet to be optimized. On-time first start percentage has been suggested to correlate with more efficient flow, and this correlation is established within the surgical space. PURPOSE: To investigate the effects of timetable targets on first case on-time first start percentage within a NORA setting. MATERIALS AND METHODS: A retrospective study of anesthesia-supported first start cases from October 2022 to April 2023 was performed to analyze the effect of timetable targets on on-time first-case starts for planned cases. Statistical analysis was calculated using Student's t-tests with statistical significance defined as p < 0.05. Additionally, analysis of variance was used to compare three or more groups, and Tukey Kramer was used to evaluate groups pairwise. RESULTS: One hundred twenty-four first start cases were included in the evaluation. After intervention with timetable targets, average patient arrival to the room time improved from 7:49 AM to 7:40 AM (p < 0.05) and procedure start time improved from 8:31 AM to 8:20 AM (p < 0.01). The percentage of procedure start times occurring prior to the goal time increased from 35 % to 58 % after the implementation (p < 0.05). With exception of Tuesdays (Anesthesia Late Start Day), on-time starts improved from 17 % to 48 % (p < 0.01) and sustained this improvement throughout the post-implementation period. CONCLUSION: Implementation of novel timetable targets yielded statistically significant improvement in first case start times. This improvement in efficiency and throughput results in increased room utilization, improved case throughput, and decreased block overrun times, all of which contribute toward increased revenues, decreased costs, and thus improved return on investment.

Comparative efficacy versus effectiveness of initial antiretroviral therapy in clinical trials versus routine care.

BACKGROUND: The applicability of clinical trial findings (efficacy) to the routine care setting (effectiveness) may be limited because of study eligibility criteria and volunteer bias. Although well-chronicled in many conditions, the efficacy versus effectiveness of antiretroviral therapy (ART) remains understudied. METHODS: A retrospective study of the University of Alabama at Birmingham 1917 Clinic Cohort evaluated ART-naive patients who started ART from 1 January 2000 through 31 December 2006. Patients received ART through clinical trials or routine care. Multivariable logistic and linear regression models were fit to evaluate factors associated with virological failure (virological failure was defined as a viral load >50 copies/mL) and change from baseline CD4+ cell count 6 and 12 months after ART initiation. Sensitivity analyses evaluated the impact of missing data on outcomes. RESULTS: Among 570 patients starting ART during the study period, 121 (21%) enrolled in clinical trials, and 449 (79%) received ART via routine care. ART receipt through routine care was not associated with viral failure at either 6 months (odds ratio [OR], 1.00; 95% confidence interval [CI], 0.54-1.86) or 12 months (OR, 1.56; 95% CI, 0.80-3.05) in primary analyses. No statistically significant differences in CD4+ cell count responses at 6 and 12 months were observed. CONCLUSIONS: Although marked differences in efficacy versus effectiveness have been observed in the therapeutic outcomes of other conditions, our analyses found no evidence of such divergence among our patients who initiated antiretroviral therapy for human immunodeficiency virus infection.

Missed visits and mortality among patients establishing initial outpatient HIV treatment.

BACKGROUND: Dramatic increases in the number of patients requiring linkage to treatment for human immunodeficiency virus (HIV) infection are anticipated in response to updated Centers for Disease Control and Prevention HIV testing recommendations that advocate routine, opt-out HIV testing. METHODS: A retrospective analysis nested within a prospective HIV clinical cohort study evaluated patients who established initial outpatient treatment for HIV infection at the University of Alabama at Birmingham 1917 HIV/AIDS Clinic from 1 January 2000 through 31 December 2005. Survival methods were used to evaluate the impact of missed visits during the first year of care on subsequent mortality in the context of other baseline sociodemographic, psychosocial, and clinical factors. Mortality was ascertained by query of the Social Security Death Index as of 1 August 2007. RESULTS: Among 543 study participants initiating outpatient care for HIV infection, 60% missed a visit within the first year. The mortality rate was 2.3 deaths per 100 person-years for patients who missed visits, compared with 1.0 deaths per 100 person-years for those who attended all scheduled appointments during the first year after establishing outpatient treatment (P = .02). In Cox proportional hazards analysis, higher hazards of death were independently associated with missed visits (hazard ratio, 2.90; 95% confidence interval, 1.28-6.56), older age (hazard ratio, 1.58 per 10 years of age; 95% confidence interval, 1.12-2.22), and baseline CD4+ cell count < 200 cells/mm(3) (hazard ratio, 2.70; 95% confidence interval, 1.00-7.30). CONCLUSIONS: Patients who missed visits within the first year after initiating outpatient treatment for HIV infection had more than twice the rate of long-term mortality, compared with those patients who attended all scheduled appointments. We posit that early missed visits are not causally responsible for the higher observed mortality but, rather, identify those patients who are more likely to exhibit health behaviors that portend increased subsequent mortality.

The therapeutic implications of timely linkage and early retention in HIV care.

Following HIV diagnosis, linkage to outpatient treatment, antiretroviral initiation, and longitudinal retention in care represent the foundation for successful treatment. While prior studies have evaluated these processes in isolation, a systematic evaluation of successive steps in the same cohort of patients has not yet been performed. To ensure optimal long-term outcomes, a better understanding of the interplay of these processes is needed. Therefore, a retrospective cohort study of patients initiating outpatient care at the University of Alabama at Birmingham 1917 HIV=AIDS Clinic between January 2000 and December 2005 was undertaken. Multivariable models determined factors associated with: late diagnosis=linkage to care (initial CD4 < 350 cells=mm3), timely antiretroviral initiation, and retention across the first two years of care. Delayed linkage was observed in two-thirds of the overall sample (n = 567) and was associated with older age (odds ratio [OR] = 1.31 per 10 years; 95%confidence interval [CI] = 1.06-1.62) and African American race (OR = 2.45; 95% CI = 1.60-3.74). Attending all clinic visits (hazard ratio [HR] = 6.45; 95% CI = 4.47-9.31) and lower initial CD4 counts led to earlier antiretroviral initiation. Worse retention in the first 2 years was associated with younger age (OR = 0.68 per 10 years;95% CI = 0.56-0.83), higher baseline CD4 count, and substance abuse (OR = 1.78; 95% CI = 1.16-2.73). Interventions to improve timely HIV diagnosis and linkage to care should focus on older patients and African Americans while efforts to improve retention should address younger patients, those with higher baseline CD4 counts, and substance abuse. Missed clinic visits represent an important obstacle to the timely initiation of antiretroviral therapy. These data inform development of interventions to improve linkage and retention in HIV care, an emerging area of growing importance.
