Article Synopsis
  • The study aims to evaluate the effectiveness of COVID-19 booster doses in preventing hospitalizations and emergency department visits, providing insight for public health policies.
  • Data was collected from over 1.2 million adults at five health systems during the Omicron variant's rise, showing that approximately 37% received a booster dose.
  • The median number needed to vaccinate (NNV) to prevent one hospitalization was 205, with lower NNV for adults aged 65 and older and those with health conditions, indicating booster effectiveness varies by age and health status.

Article Synopsis
  • A study evaluated the effectiveness of the BNT162b2 COVID-19 vaccine on children and adolescents during the Omicron BA.4/BA.5 period, focusing on its ability to protect against mild to moderate and severe cases of COVID-19.
  • The research compared data from nearly 10,000 emergency department cases and over 70,000 controls, finding that vaccine effectiveness decreased over time, especially during the Omicron variant's spread.
  • It concluded that while the vaccine offered significant protection initially, especially against hospitalizations, booster doses enhanced effectiveness, highlighting the importance of completing the vaccination schedule for children and adolescents.

Article Synopsis
  • The Omicron sublineages BA.4 and BA.5 show increased immune evasion, reducing the effectiveness of COVID-19 mRNA vaccines in preventing illness among immunocompetent adults.
  • A study across 10 states focused on vaccinated adults, assessing the effectiveness of 2 to 4 vaccine doses during periods of BA.4 and BA.5 circulation, and examining the severity of COVID-19 in hospitalized patients across different Omicron sublineages.
  • Results indicated that in a large sample of emergency department and hospitalized patients, a significant portion tested positive for SARS-CoV-2, highlighting ongoing challenges in vaccine effectiveness and patient outcomes during these variant periods.

Article Synopsis
  • A study was conducted in the U.S. to evaluate the effectiveness of COVID-19 mRNA vaccines and previous SARS-CoV-2 infections during Delta and Omicron variant periods.
  • The research found that both 2- or 3-dose vaccinated individuals and those with a prior infection had high protection against hospitalizations and emergency care during the Delta period (91%-97%), but this protection decreased during the Omicron period (77%-90%).
  • The results highlight that staying up-to-date with COVID-19 vaccinations continues to offer significant protection against severe illness, regardless of prior exposure to the virus.

Purpose: Few studies have determined whether clinician usage of a community health information exchange (HIE) directly improves patient care transitions. We hypothesized that lookup in the HIE by primary care physicians of patients recently released from the hospital would increase the time until hospital reuse.

Methods: We identified a retrospective cohort of 8,216 hospital inpatients aged over 18 years that were discharged from January 1, 2021 through November 30, 2021 using the Paso del Norte Health Information Exchange, in El Paso County, Texas.

Article Synopsis
  • The 2021-2022 influenza season in the U.S. experienced a resurgence following very low activity the previous year, primarily due to the A(H3N2) virus strain.
  • A study analyzed vaccine effectiveness (VE) among adults over 18 through hospital and urgent care visits, revealing that vaccination reduced the odds of influenza by 25% for both ED/UC encounters and hospitalizations.
  • The vaccine was notably less effective for older adults (≥65 years) and those with weakened immune systems, indicating a need for better vaccine formulations against A(H3N2) strains.

Background: Coronavirus disease 2019 (COVID-19) vaccination coverage remains lower in communities with higher social vulnerability. Factors such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposure risk and access to healthcare are often correlated with social vulnerability and may therefore contribute to a relationship between vulnerability and observed vaccine effectiveness (VE). Understanding whether these factors impact VE could contribute to our understanding of real-world VE.

Article Synopsis
  • The Advisory Committee on Immunization Practices (ACIP) recommended a 3-dose primary series and subsequent booster doses of mRNA COVID-19 vaccines specifically for immunocompromised adults, acknowledging the rise of the Omicron variant.
  • Data from a study indicate that the effectiveness of the vaccines varies, with a 36% effectiveness against hospitalization after 2 doses, increasing to 69% after 3 doses, but dropping to 44% after more than 90 days post-3rd dose during the Omicron variant period.

The foundational role of health information exchanges (HIEs) is to facilitate communication between clinical partners in real time. Once this infrastructure for the secure and immediate flow of patient information is built, however, HIEs can benefit community public health and clinical care in myriad other ways that are in line with their mission, goals, patient privacy, and funding structures. We encourage the development of community-integrated HIEs and list specific steps that can be taken toward community integration.

Background: Defects resulting from gynecologic oncology resections can range from small external defects to total exenterations, requiring complex pelvic reconstruction. We aim to investigate the patient and surgical factors that influence complication rates, reoperation rates, and length of stay. We hypothesize that this patient cohort will have high complication and reoperation rates that are likely most affected by their medical and extirpative surgery factors, with less direct impact from their reconstructive surgery procedures.

Background: Pressure ulcers represent a particularly difficult disease process and remain a financially important entity. The underlying bone in advanced ulcers may harbor osteomyelitis. Radiologic diagnosis of osteomyelitis is confounded by chronic pressure and shear.

Background: Abdominal component separation is used commonly for closure of midline abdominal wounds. The value of each step in reducing tension has not been studied. Our aim was to test whether component separation decreases tension in the midline closure and to quantify the value of each procedural step.

Simultaneous breast augmentation and mastopexy is a common procedure often considered to be one of the most difficult cosmetic breast surgeries. One-stage augmentation mastopexy was initially described more than 50 years ago. The challenge lies in the fact that the surgery has multiple opposing goals: to increasing the volume of a breast, enhance the shape, and simultaneously decrease the skin envelope.

Background: Occipital neuralgia is a headache syndrome characterized by paroxysmal headaches localizing to the posterior scalp. The critical diagnostic feature is symptomatic response to local anesthetic blockade of the greater or lesser occipital nerve. Further characterization is debated in the literature regarding the diagnosis and optimal management of this condition.

Background: Communication errors are the primary factor contributing to all types of sentinel events including those involving surgical patients. One type of communication error is mislabeled specimens. The extent to which these errors occur is poorly quantified.

Background: Wrong-site surgery can be a catastrophic event for a patient, caregiver, and institution. Although communication breakdowns have been identified as the leading cause of wrong-site surgery, the efficacy of preventive strategies remains unknown. This study evaluated the impact of operating room briefings on coordination of care and risk for wrong-site surgery.
