Death and Disability Reported with Cases of Vaccine Anaphylaxis Stratified by Administration Setting: An Analysis of the Vaccine Adverse Event Reporting System from 2017 to 2022.

The serious nature of post-vaccination anaphylaxis requires healthcare professionals to be adequately trained to respond to these hypersensitivity emergencies. The aim of this study was to compare outcomes reported with cases of vaccine anaphylaxis stratified by administration setting. We queried reports in the Vaccine Adverse Event Reporting System (VAERS) database from 2017 to 2022 and identified cases involving anaphylaxis with an onset within one day of vaccine administration. The primary outcome was the combined prevalence of death or disability for each setting while the secondary outcome was the prevalence of hospitalization. Adjusted (age, sex, prior history of allergy, vaccine type) odds ratios (aOR) and associated 95% confidence intervals (CI) were calculated using logistic regression analysis. A total of 2041 cases of anaphylaxis comprised the primary study cohort with representation in the sample from all 50 US states and the District of Columbia. The mean age was 43.3 ± 17.5 years, and most cases involved women (79.9%). Cases of anaphylaxis were reported after receiving a coronavirus vaccine (85.2%), influenza vaccine (5.9%), tetanus vaccine (2.2%), zoster vaccine (1.6%), measles vaccine (0.7%), and other vaccine (4.5%). Outcomes associated with reports of vaccine anaphylaxis included 35 cases of death and disability and 219 hospitalizations. Compared with all other settings, the aOR of death and disability when anaphylaxis occurred was 1.92 (95% CI, 0.86-4.54) in a medical provider's office, 0.85 (95% CI, 0.26-2.43) in a pharmacy and 1.01 (95% CI, 0.15-3.94) in a public health clinic. Compared with all other settings, the aOR of hospitalization when anaphylaxis occurred was 1.02 (95% CI, 0.71-1.47) in a medical provider's office, 1.06 (95% CI, 0.72-1.54) in a pharmacy, and 1.12 (95% CI, 0.61-1.93) in a public health clinic. An analysis of a national database across six years revealed no significant differences in the odds of death/disability and odds of hospitalization associated with post-vaccination anaphylaxis in the medical office, pharmacy, and public health clinic compared with all other settings. This study expands our understanding of the safety of immunization services and reinforces that all settings must be prepared to respond to such an emergency.

Topical Morphine Gel as a Systemic Opioid Sparing Technique.

Use of topical morphine gel was explored retrospectively for treatment of painful chronic wounds in hospitalized adults. Systemic opioid use and pain intensity were characterized before and after morphine gel initiation using morphine equivalent daily dose (MEDD) and the Defense and Veterans Pain Rating Scale (DVPRS) score at 24 hours before compared to 24 hours, 48 hours, and one week after morphine gel initiation. Twenty-three patients received 371 applications of topical morphine gel. The median number of applications received was 8.0 [5.0 to 26.0] per patient. Median change in MEDD 24 hours after morphine gel initiation was 0.0 mg [-15.3 to 11.3] (n = 21), 48 hours after was -4.4 mg [-27.5 to 8.8] (n = 20), and one week after was -7.5 mg [-41.9 to -0.3] (n = 12). Median change in DVPRS score 24 hours after morphine gel initiation was 0.0 [-0.5 to 1.5] (n = 13), 48 hours after was -0.5 [-3.25 to 0.0] (n = 14), and one week after was 1.0 [-1.0 to 3.5] (n = 9). In this single-center analysis, patients with painful chronic wounds treated with morphine gel required lower doses of systemic opioids. Topical morphine gel may provide analgesia while sparing systemic opioid use.

Early onset delirium incidence and risk factors in hematology oncology patients admitted to the intensive care unit: A retrospective cohort study.

Background: Delirium occurs frequently in intensive care unit (ICU) patients; however, there are limited data evaluating its impact on critically ill hematology-oncology patients. We aimed to determine the incidence and risk factors for early-onset delirium development in hematology-oncology patients admitted to the ICU. Methods: This single-center, retrospective cohort study evaluated the primary outcome of incident delirium within 7 days of ICU admission in adults admitted to the hematology-oncology medical or surgical ICU. Patients with delirium (DEL) were compared to those without (No-DEL) for evaluation of secondary endpoints including hospital mortality, ICU, and hospital length of stay (LOS). Multivariable logistic regression modeling was performed to identify independent risk factors for delirium. Results: Delirium occurred in 125 (51.2%) of 244 patients. Inhospital mortality was significantly higher in the DEL vs. No-DEL group (32.8% vs. 15.1%, P = 0.002). Median (1st and 3rd quartiles) ICU and hospital LOS were significantly longer in the delirium group, respectively (6 [4-10] days vs. 3 [2-5] days, P < 0.001, and 21 [14-36] days vs. 12 [8-22] days, P < 0.001). Higher Sequential Organ Failure Assessment score, high-dose corticosteroids, mechanical ventilation (MV), and brain metastases were each independently, associated with an increased delirium risk. Conclusion: Hematology-oncology patients admitted to the ICU frequently develop delirium. Consistent with literature in nonhematology-oncology critically ill patients, identified independent risk factors for delirium were MV and organ dysfunction. Risk factors unique to the critically ill hematology-oncology patient population include high-dose corticosteroids and brain metastases. Further research is needed to evaluate strategies to mitigate delirium development in this population based on risk assessment.
