Risk Factors for Post-Discharge Adverse Outcomes Following Hospitalization Among Older Adults Diagnosed With Elder Mistreatment

Using 100% Medicare data files, this study explored whether primary elder mistreatment (EM) diagnosis, EM type, and facility type were associated with 3-year mortality and 1-year unplanned hospital readmission among older patients diagnosed with EM with hospital discharge from 10/01/2015 through 12/31/2018 (n = 11,023). We also examined outcome differences between older patients diagnosed with EM and matched non-EM patient controls. Neglect by others was the most common EM diagnosis. Three-year mortality was 56.7% and one-year readmission rate was 53.8%. Compared to matched non-EM patient controls, older EM patients were at an increased risk of mortality and readmission. Among patients diagnosed with EM, patients with a secondary (vs. primary) diagnosis and those discharged from a skilled nursing facility (vs. acute hospital) were at an increased risk for both mortality and readmission. Compared to other EM types, patients diagnosed with neglect by others had a greater risk for mortality following discharge.

Severe Acute Respiratory Syndrome Coronavirus 2 Neutralizing Antibody Responses After Community Infections in Children and Adults

Background

We compared postinfection severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) neutralizing antibody (nAb) responses among children and adults while the D614G-like strain and Alpha, Iota, and Delta variants circulated.

Methods

During August 2020-October 2021, households with adults and children were enrolled and followed in Utah, New York City, and Maryland. Participants collected weekly respiratory swabs that were tested for SARS-CoV-2 and had sera collected during enrollment and follow-up. Sera were tested for SARS-CoV-2 nAb by pseudovirus assay. Postinfection titers were characterized with biexponential decay models.

Results

Eighty participants had SARS-CoV-2 infection during the study (47 with D614G-like virus, 17 with B.1.1.7, and 8 each with B.1.617.2 and B.1.526 virus). Homologous nAb geometric mean titers (GMTs) trended higher in adults (GMT = 2320) versus children 0-4 (GMT = 425, P = .33) and 5-17 years (GMT = 396, P = .31) at 1-5 weeks postinfection but were similar from 6 weeks. Timing of peak titers was similar by age. Results were consistent when participants with self-reported infection before enrollment were included (n = 178).

Conclusions

The SARS-CoV-2 nAb titers differed in children compared to adults early after infection but were similar by 6 weeks postinfection. If postvaccination nAb kinetics have similar trends, vaccine immunobridging studies may need to compare nAb responses in adults and children 6 weeks or more after vaccination.
