Research question
Do two practice formats differ in six-month retention?
Method and context
Random allocation of 163 staff to short self-practice or mastery practice after video/manikin familiarization; knowledge and manikin reassessment at six months in 142 completers.
Study summary
Adjacent individual emergency-skill evidence with delayed testing; not an evaluation of CPX team-command transfer.
Findings
Table 4 reports mean six-month compression scores of 96.6 and 96.8, without a statistically significant between-group difference.
Contribution
Separates immediate acquisition from delayed knowledge and performance testing without real-time feedback.
Interpretation limits
Single centre, controlled testing and per-protocol analysis; 21/163 withdrew. Abstract estimates differ from Table 4; this summary follows the table and does not establish equivalence.
A question for further research
Project proposal: reassess a new CPX decision task at six months, recording refresher exposure and attrition; CPR results do not validate CPX.
A starting point for a study design: extend the literature search, specify methods and outcomes, and assess ethics requirements for the data and participants.
Connect evidence to KSEC / OBE
Project-proposed critical-appraisal evidence, not research findings or accreditation criteria from the original authors.
- K
- Explain the question, concepts and findings with locators in the original.
- S
- Compare methods, variables and limitations with another study before designing a test or CPX.
- E
- Separate reported results from your proposals, cite originals and examine implications for vulnerable groups.
- C
- Record responses to critique and revisions after new evidence. Observe behaviour repeatedly, not from a single reading.
