Evidano is an AI-powered qualitative data analysis platform that automates coding, cross-segment comparison, and visualization while preserving data privacy and audit trails. This qualitative analysis of ECG training examines how Rapid Cycle Deliberate Practice (RCDP) changed electrocardiographic monitoring judgment in critical cardiac care nurses. If you run qualitative studies, UX research, or clinical training evaluations, this post gives three concrete payoffs: (1) the key patterns the PLOS One study (published July 6, 2026) found (n=13; interviews avg. 43 min), (2) a reproducible text-analysis workflow you can run in Evidano (www.evidano.com) to map noticing→interpreting→responding→reflecting, and (3) a 7-step checklist to turn transcripts into stakeholder-ready evidence. The original study is available at PLOS One. This post translates the paper’s phenomenological findings into actionable qualitative-research operations (coding, co-occurrence, segment comparison) you can automate securely in Evidano while preserving audit trails and participant privacy. Ethics note: this content is research-focused and non-diagnostic.
Key Takeaways
The PLOS One phenomenological study found that Rapid Cycle Deliberate Practice (RCDP) produced perceived shifts across perceptual, cognitive, behavioral, and professional-identity domains in CCU nurses.
The reported changes mapped to Tanner’s noticing, interpreting, responding, and reflecting phases and were observed in interviews with 13 nurses collected Apr–Jul 2025 and published 6 Jul 2026.
- The sample included 13 CCU nurses with maximum variation in experience (3–20 years) and average interviews of about 43 minutes.
- Participants described immediate perceptual change from isolated numeric/alarm focus to gestalt rhythm recognition and cognitive change from rule-based matching to intuition plus rapid evidence checks.
- The study used Van Manen phenomenology, inductive coding in NVivo, then mapped themes to Tanner’s noticing→interpreting→responding→reflecting framework.
Fast take: what the PLOS One paper shows
The PLOS One phenomenological study of 13 CCU nurses reports perceived shifts across Tanner’s clinical judgment phases after RCDP training.
In brief: a phenomenological study of 13 CCU nurses (data collected Apr–Jul 2025; published 6 Jul 2026) reports perceived shifts across Tanner’s clinical judgment phases after RCDP training: from fragmented monitoring to holistic pattern recognition, from rule-based matching to integrated intuition and evidence, from hesitant reactivity to proactive responses, and toward a stronger professional identity.

What happened (method and core results)
The authors implemented a three-phase, station-based RCDP program and then interviewed nurses who completed the training, analyzing transcripts with inductive coding in NVivo mapped to Tanner’s framework.
The authors implemented a three-phase, station-based RCDP program (rhythm identification, waveform morphology, arrhythmia classification, emergency response) then interviewed nurses who completed training. Analysis used inductive coding in NVivo, then mapped themes to Tanner’s noticing→interpreting→responding→reflecting framework.
- Participants reported immediate perceptual shifts: from isolated numeric/alarm focus to gestalt rhythm recognition.
- Cognitive change: breakthrough moments where intuition plus rapid evidence checks replaced mechanical textbook matching.
- Behavioral change: increased confidence to initiate interdisciplinary action.
- Identity shift: nurses described an expanded ethical responsibility and ongoing learning commitment.
Implications for researchers and clinical educators: qualitative analysis of ECG training
These findings show that qualitative protocols evaluating training interventions must capture perceptual language, breakthrough narratives, and identity statements in addition to accuracy scores.
If you evaluate training interventions (simulation, RCDP, or blended curricula), these findings show why your qualitative protocol must capture more than accuracy scores, capture perceptual language, breakthrough narratives, and identity statements.
- Design interviews to probe the noticing→interpreting→responding→reflecting continuum (use Tanner’s model as a sensitizing framework).
- Triangulate: pair interview narratives with timestamps of simulation runs or actual ECG strips to link talk to action.
- Measure sustainment: collect follow-up interviews or short surveys at 3/6/12 months to track retention and identity change.

Import & secure storage
Evidano ingests transcripts, audio files, and field notes into secure storage so you can reproduce this study’s qualitative analysis.
Ingest transcripts, audio files, and field notes directly into Evidano. Use transcription with custom dictionary (medical terms, local names), PII redaction, and end-to-end encryption so raw data remain private and audit-ready.
Thematic + framework mapping
Evidano supports inductive theme extraction and mapping emergent codes to Tanner’s noticing→interpreting→responding→reflecting framework.
Run an inductive theme extraction, then map emergent codes to Tanner’s noticing→interpreting→responding→reflecting framework using Evidano’s hierarchical code→subcode visualizer. Export codebook for peer-review and audit.
Segment & compare
Evidano lets you compare segments such as novices versus experienced nurses or pre/post training interviews to surface statistically flagged differences.
Use cross-segment analysis to compare novices vs. experienced nurses, pre/post training quotes frequency, or early vs. late interviews. Evidano shows theme frequencies, co-occurrence networks, and statistically flagged differences between segments.
Evidence packages & stakeholder reports
Evidano produces clickable reports with representative quotes and visualizations that are presentation-ready for educators and hospital leadership.
Generate clickable reports with representative quotes, co-occurrence graphs, and timeline views. These outputs are presentation-ready for educators and hospital leadership to justify RCDP scaling.
Iterate with AI-assisted synthesis (no third-party training)
Evidano provides secure AI-assisted synthesis over your uploaded corpus without training external models on your data.
Use Evidano’s secure AI chat over your uploaded corpus to ask targeted synthesis questions (e.g., “Show all quotes mentioning ‘pause-coach-resume’ and confidence”). Evidano’s models are tuned for qualitative research and your data are never used to train external models.

What did the PLOS One study find about RCDP's effects on CCU nurses?
The study found that RCDP was associated with perceived shifts across perceptual, cognitive, behavioral, and identity domains among CCU nurses.

The study interviewed 13 CCU nurses and collected data from April to July 2025.
The sample purposefully varied in experience (3–20 years) and average interview length was about 43 minutes; the paper was published on July 6, 2026.
Which qualitative methods and frameworks did the authors use?
The authors used Van Manen phenomenology with inductive coding in NVivo and then mapped emergent themes to Tanner’s noticing→interpreting→responding→reflecting framework.
