ReviewDark Data in Real-World Evidence: Challenges, Implications, and the Imperative of Data Literacy in Medical Research.
Randomized controlled trials (RCTs) and real-world evidence (RWE) studies are crucial and complementary in generating clinical evidence. RCTs provide controlled settings to validate the clinical effect of specific drugs or medical devices, while RWE integrates extrinsic factors, encompassing external influences affecting real-world scenarios, thus challenging RCT results in practical applications. In this study, we explore the impact of extrinsic factors on RWE outcomes, focusing on "dark data," which refers to data collected but not used or excluded from the analyses. ⋯ Connecting RCTs and RWEs requires medical data literacy, enabling clinicians to decipher meaningful insights. In the big data and artificial intelligence era, medical staff must navigate data complexities while promoting the core role of medicine. Prepared clinicians will lead this transformative journey, ensuring data value shapes the medical landscape.

Opioid Prescription and Long-Term Survival Outcomes in Adults: A Nationwide Cohort Study in Korea.
We aimed to investigate the association between short- and long-term opioid use and long-term mortality in Korea. ⋯ Both short and long-term opioid prescriptions were associated with increased long-term mortality among the Korean adult population.

Multicenter StudyPre-Sepsis Length of Hospital Stay and Mortality: A Nationwide Multicenter Cohort Study.
Prolonged length of hospital stay (LOS) is associated with an increased risk of hospital-acquired conditions and worse outcomes. We conducted a nationwide, multicenter, retrospective cohort study to determine whether prolonged hospitalization before developing sepsis has a negative impact on its prognosis. ⋯ Extended LOS before developing sepsis is associated with higher in-hospital mortality. More careful management is required when sepsis occurs in patients hospitalized for ≥ 5 days.
