Reflections From School Communities in Underserved Populations on Childhood COVID-19 Vaccination

OBJECTIVES

Outbreaks in vaccine-preventable diseases among children have increased, primarily among under- or unvaccinated subgroups. The influence and interaction of a child's school community on parental health care decisions, such as vaccination, has not been explored. Our study examined childhood coronavirus disease 2019 (COVID-19) vaccine hesitancy within the context of school communities.

METHODS

This study combines data from 4 independent research studies funded by the National Institutes of Health Rapid Acceleration of Diagnostics Underserved Populations Return to School Initiative. We examined focus group data to better understand the apprehension surrounding parental and child COVID-19 vaccination among underserved school populations.

RESULTS

Across all study sites, 7 main themes emerged with regard to COVID-19-related vaccination concerns for children: (1) potential side effects, (2) vaccine development, (3) misinformation (subthemes: content of vaccine and negative intent of the vaccine), (4) vaccine effectiveness, (5) timing of vaccine administration/availability for children, (6) fear of needles, and (7) mistrust.

CONCLUSIONS

School settings offered unique access to youth and family perspectives in underserved communities. Our studies highlighted several factors contributing to COVID-19 vaccine hesitancy in school communities, which align with existing literature on vaccine hesitancy. These concerns centered primarily on potential harm of vaccines, as well as misinformation, mistrust, and timing of vaccines. Related recommendations for increasing vaccination rates are provided. Developing specific strategies that address parent and child concerns will be critical to reducing health inequities related to COVID-19 vaccination.

Postoperative bleeding complications in patients with hemophilia undergoing major orthopedic surgery: A prospective multicenter observational study

BACKGROUND

Persons with hemophilia (PWH) are at risk for chronic hemophilic arthropathy (HA). Joint replacement surgery may be used to relieve intractable pain and/or restore joint function.

OBJECTIVES

This multicenter, prospective, observational cohort study evaluated the rate of bleeding during the postoperative period after total hip (THA) or knee arthroplasty (TKA).

PATIENTS/METHODS

We included PWH of any severity ≥18 years of age who were undergoing THA or TKA. Clinical decisions were made at the discretion of the treating physician according to local standards of care. Clinical data were prospectively recorded. Major bleeding was defined as bleeding in a critical site, bleeding that resulted in either a 2 g/dl or greater decrease in hemoglobin during any 24-h period, or transfusion of two or more units of packed red blood cells.

RESULTS

One hundred thirty-one procedures (98 TKA and 33 THA) were performed, 39 (29.8%) of which were complicated by major bleeding, including 46% of THA and 25% of TKA. The risk of major bleeding was increased in THA compared to TKA (OR 2.50, p = .05), and by the presence of an inhibitor (OR 4.29, p = .04), increased BMI (OR 4.49 and 6.09 for overweight and obese, respectively, compared to normal BMI, each p < .01), and non-use of an antifibrinolytic medication (OR 3.00, p = .03). Neither continuous clotting factor infusion (versus bolus infusion) nor pharmacologic thromboprophylaxis were associated with bleeding risk.

CONCLUSIONS

The bleeding risk remains substantial after THA and TKA in PWH, despite factor replacement. Use of antifibrinolytic medications is associated with decreased risk.
