To evaluate the effectiveness of short-duration self-learning (SSL) and mastery learning (ML) strategies on the acquisition and 6-month retention of cardiopulmonary resuscitation (CPR) skills and basic life support (BLS) knowledge among hospital administrative staff in Thailand.
Comparative assessment of two CPR training strategies.
Tertiary-level academic institution in Thailand.
A total of 163 hospital administrative staff aged ≥18 years without prior BLS certification were enrolled and randomly allocated to either the SSL group (n=82) or the ML group (n=81). Participants with previous CPR certification, medical limitations preventing chest compressions or those unwilling to attend the 6-month retention test were excluded. 71 participants in each group completed the 6-month follow-up.
All participants viewed an 8 min self-directed instructional video on BLS and subsequently performed CPR practice using real-time feedback manikins. The SSL group practised independently for up to five 1 min sessions, while the ML group practised until achieving a predefined mastery threshold (QCPR (Quality Cardiopulmonary Resuscitation) score >90%).
The primary outcome was CPR skill retention at 6 months, measured by QCPR overall performance score. Secondary outcomes included observational BLS performance (scene safety, responsiveness, emergency activation, breathing assessment and correct hand placement), knowledge retention scores and the number of attempts required to achieve mastery in the ML group.
Both SSL and ML groups demonstrated significant improvement in CPR performance and BLS knowledge immediately after training (p
Both SSL and ML effectively enhanced CPR performance and knowledge retention among non-medical hospital staff. SSL offers a practical, resource-efficient and scalable approach for CPR training in large-scale community or institutional settings. Future studies should investigate the cost-effectiveness and optimal refresher frequency for sustaining CPR competency.

This study aimed to optimize microencapsulation conditions for Phy-Blica-O (PBO), a traditional Thai polyherbal tonic, and to assess the safety of its consumer-accepted herbal tea formulation, Phy-Blica-D (PBD). PBO decoction and its phenolic-rich extract were spray-dried at different inlet temperatures (140°C, 180°C) and maltodextrin-gum Arabic ratios. Encapsulation efficiency was highest at 140°C with maltodextrin alone, while antioxidant activity was greatest in microcapsules prepared at 180°C with a 6:4 maltodextrin to gum Arabic ratio, as shown by DPPH, ABTS, and FRAP assays. PBD demonstrated strong in vitro antioxidant activities and was subsequently assessed in a 90-day subchronic toxicity study in Wistar rats. No treatment-related mortality, clinical abnormalities, organ toxicity, or hematological or biochemical disruptions were seen at doses up to 300 mg/kg/day, indicating a NOAEL above this level. These findings suggest that optimized PBO microcapsules and the PBD tea blend are safe, antioxidant-rich functional ingredients with strong potential for commercialization in complementary and integrative medicine.
