The Omicron variant of SARS-CoV-2 has emerged as the predominant strain of COVID-19 since 2022. Its association with prior vaccines remained under investigation.

Retrospective cohort study.

Clinical data for patients, from 1 May 2022 to 31 January 2023, were extracted from the Chi-Mei Medical Center, Chiali electronic medical record databases.

Hospitalised COVID-19 patients in dedicated wards were enrolled in the study. Cases of COVID-19 reinfection and relapse were also included. Patients who did not have COVID-19, those with PCR repositivity, or those with incomplete laboratory data were excluded.

Various doses of vaccines included primary series, additional dose and booster. The types of vaccines included ChAdOx1-S, mRNA-based vaccines and recombinant protein vaccine. The interval between the last vaccination date and the diagnosis date of COVID-19 was assessed.

The primary outcome was all-cause mortality by day 30. The secondary outcomes were severe disease of COVID-19 and 90-day survival.

Among 469 cases, the adjusted HR for 30-day mortality in vaccinated compared with unvaccinated patients was 0.831 (95% CI 0.541 to 1.277; p=0.398), indicating no statistically significant association. Age, Charlson Comorbidity Index (CCI), quick Sequential Organ Failure Assessment score and administration of dexamethasone were recognised as powerful predictors for survival in multivariable analysis. In subgroup analysis, a statistically significant association with better 30-day survival was observed among patients aged

Vaccination was associated with lower mortality in younger or low-CCI patients, but not in older or highly comorbid patients.

The financial impact on trauma patients can be devastating. Although Taiwan has universal health insurance coverage, medical bill reimbursement cannot compensate for the damage to a person’s ability to work. The aim of this study was to investigate personal financial outcomes after major trauma.

A retrospective cohort study.

Nationwide data from Taiwan’s National Health Insurance Research Database.

This study included all patients with major trauma (injury severity score ≥16) in Taiwan from 2003 to 2007, and a 10-year follow-up was conducted. Patients aged 18–70 were enrolled. Patients who returned to work after trauma (RTW) and those who did not return to work (non-RTW) were compared. Basic demographics and short-term outcomes were analysed, and the 10-year trend of income variation was calculated.

The primary outcomes are the ratio of non-RTW after major trauma, and the independent risk factors for non-RTW. The secondary outcome is the 10-year trend of income variation of major trauma patients.

5965 patients were included, with 4741 (79.5%) in the RTW group and 1224 (20.5%) in the non-RTW group. Hospital-acquired pneumonia, urinary tract infection, prolonged intensive care unit length of stay (LOS) and prolonged hospital LOS were identified as independent risk factors for future non-RTW. The mean monthly income of all patients declined in the three consecutive years postinjury and slowly returned to the preinjury level 9 years after the injury.

Loss of working ability was noted in 20.5% of major trauma patients, and the income level for all patients did not recover to the preinjury level until 9 years after the injury. Further welfare planning beyond the extent of the National Health Insurance programme should be made to protect the financial shortcomings experienced by these patients.

ISRCTN18269986.

We aimed to understand the factors affecting psychological well-being of patients undergoing haemodialysis (HD). First, we explored how physical symptom severity, emotional distress and social support influence psychological well-being. Second, we examined the impact of different types of social support. Third, we investigated whether any variables mediate the relationship with psychological well-being.

A cross-sectional study, a type of observational design, was conducted on patients at a medical centre in Taiwan in 2020.

A total of 117 outpatients who had undergone regular HD for at least 3 months were enrolled.

The psychological well-being was assessed through self-report questionnaires.

We found that emotional distress (β=–0.25, p=0.033) had a significant negative impact on psychological well-being. However, the presence of appraisal support mitigated this effect. Specifically, appraisal support fully mediated the adverse impact of emotional distress on psychological well-being. In addition, the severity of physical symptoms was generally mild and did not influence psychological well-being.

Receiving appraisal support from family, friends and healthcare professionals not only alleviates emotional distress but also enhances psychological well-being both directly and indirectly among patients undergoing HD. Healthcare professionals should address issues of personal importance while serving as consultants, educators and evaluators to support patients in managing their chronic condition.
