Adverse Events Among Hospitalized Patients in China

10. juli 2026 oppdatert av: Wei Jiang, Peking Union Medical College Hospital

Adverse Events Among Hospitalized Patients: A Multicenter Evaluation of Four Detection Methods

The goal of this observational study is to learn about the incidence and characteristics of adverse events (AEs) among hospitalized patients in China and to compare 4 commonly used methods for detecting these events. The main questions it aims to answer are:

How common are AEs among hospitalized patients, and what are their characteristics (types, severity, and preventability) in China? How do 4 commonly used methods, including the Harvard Medical Practice Study (HMPS), Global Trigger Tool (GTT), Patient Safety Indicators (PSIs), and incident reporting systems (IRSs), compare in detecting AEs? Researchers review randomly selected medical records from 5 hospitals in China to identify AEs, assess their type, severity, and preventability, and evaluate the performance of the 4 detection methods.

Studiepopulasjon

The study population consisted of inpatient admissions to 5 participating public general hospitals in Beijing, China, during 2024. Eligible admissions were identified according to predefined inclusion and exclusion criteria. Stratified random sampling was used, with sample sizes allocated in proportion to hospital admission volumes. Within each site, eligible admissions were randomly selected with equal selection probabilities. The final study sample included 2,843 admissions.

Beskrivelse

Inclusion Criteria:

age ≥18 years and a length of stay of at least 24 hours

Exclusion Criteria:

Patients admitted primarily for psychiatric disorders, palliative care, or rehabilitation were excluded.
