Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, and documents. According to the PLOS One article published on July 30, 2026, trial staff in the UK experience a persistent tension between over-reporting and under-reporting that reduces efficiency and can obscure safety signals. This post explains the study findings and shows how AI-enabled qualitative research methods can accelerate synthesis, build shared evidence, and support risk-proportionate safety reporting for clinical trial teams.
Key Takeaways
According to the PLOS One study published on July 30, 2026, UK clinical trials unit (CTU) staff described an overarching theme of “Walking on a tightrope: Making justifiable decisions” when deciding what safety data to collect and report. PLOS One
- 23 CTU staff participated across four focus groups between 01-July-2024 and 04-March-2025, according to PLOS One (published July 30, 2026).
- Participants worked across 10 of 52 UK-registered trials units and reported a mean of 13.3 years’ trial experience (SD 9.5), as reported in PLOS One on July 30, 2026.
- The study identified one overarching theme and five subthemes (uncertainty, red tape, competing demands, lack of clarity, and variable experience), and recommended clearer regulator guidance, CTU knowledge-sharing, and role-specific training, according to PLOS One (July 30, 2026).
What Happened and how the study was done
Answer: The study ran four online focus groups with CTU staff to surface barriers and solutions to efficient safety reporting, and used reflexive thematic analysis to synthesise the transcripts.
According to PLOS One (published July 30, 2026), the research team conducted four online focus groups between 01-July-2024 and 04-March-2025 and audio/video recorded sessions that were auto-transcribed in Microsoft Teams.
According to PLOS One (July 30, 2026), 24 staff consented and 23 took part; demographic data were captured for 20 participants, who worked across 10 of 52 registered UK CTUs and had a mean 13.3 years experience (SD 9.5).
According to PLOS One (July 30, 2026), the analytic approach was Reflexive Thematic Analysis with coding performed inductively in NVivo v11.7, producing one overarching theme and five subthemes.
Findings Snapshot
| Date / Period | Metric | Value (from study) | Implication for CTUs |
|---|---|---|---|
| 01-Jul-2024 to 04-Mar-2025 | Focus groups conducted | 4 focus groups | Qualitative breadth from multiple CTUs, supports transferability |
| July 30, 2026 | Publication date | PLOS One article published | Findings contextualised before/after UK regulatory changes |
| Sample | Participants | 23 CTU staff (24 consented, 1 withdrew) | Practical operational insight from experienced staff |
| Experience | Mean years in trials | 13.3 years (SD 9.5) | High experiential knowledge shaped themes |
| Trial phases | Most common phases | Phase II N=10, Phase III N=11 | Findings weighted toward later-phase oncology trials |
Implications for CTU managers and trialists
Answer: CTU leaders should prioritise role-specific training, shared decision records, and pragmatic SOPs to enact risk-proportionate reporting.
According to PLOS One (July 30, 2026), participants reported that uncertainty about consequences and fear of regulatory reprisal drive conservative reporting that increases workload and may obscure signals.
According to PLOS One (July 30, 2026), participants recommended three practical steps: use regulator resources (MHRA, HRA, ICH), create CTU networks for shared learning, and establish mentoring or case-study repositories to increase confidence.
According to PLOS One (July 30, 2026), recent UK legislation that came into force on 28-Apr-2026 reduces duplicative reporting (for example SUSARs and Annual Safety Reports need only be reported to MHRA), which frees staff time but requires local implementation plans.
How Evidano Helps: from problem to solution
Problem: Slow synthesis of interview data → Solution: Thematic and cross‑segment analysis
Answer: AI-enabled qualitative tools reduce manual coding time and surface themes consistently across transcripts.
Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, and documents.
Evidano maps verbatim transcripts to themes, counts co-occurrence, and produces hierarchical code→subcode visualisations to help teams act on evidence faster; this directly addresses the Reflexive Thematic Analysis workload described in PLOS One (July 30, 2026).
Use case: ingest the four focus-group transcripts, run automated inductive coding, then inspect suggested code clusters and export a themed evidence brief for stakeholders in hours rather than weeks.
Problem: Lack of shared examples and templates → Solution: searchable case‑study library and AI chat
Answer: A centralised repository with searchable case examples reduces uncertainty and supports consistent decisions.
According to PLOS One (July 30, 2026), participants asked for platforms to share case studies and templates; Evidano supports document ingestion and AI chat over your documents enabling searchable, sharable learnings across CTUs.
You can combine trial documents, reference safety information, and annotated examples and then query them with AI to produce standardised wording or template investigator brochure excerpts aligned to the new April 28, 2026 regulatory framework.
Problem: Inconsistent transcription and redaction → Solution: accurate transcription with PII controls
Answer: High-quality, research-focused transcription keeps analyses reproducible and compliant.
Evidano provides transcription with custom dictionaries and PII redaction, which matches the study’s method of cleaning and pseudonymising transcripts as described in PLOS One (July 30, 2026).
This ensures that your focus group or site investigator discussions are ready for coding, audit trails, and regulator-facing outputs.

FAQ: qualitative analysis of safety reporting
What were the main barriers to efficient safety reporting identified by the PLOS One study?
Answer: The study found five subthemes causing inefficiency: uncertainty about consequences, bureaucratic red tape, competing demands, lack of clarity and transparency, and variable staff experience (PLOS One, July 30, 2026).
Supporting detail: PLOS One (July 30, 2026) reports that participants said over-reporting creates noise and under-reporting misses low-grade toxicities, and they recommended clearer regulator guidance and CTU knowledge-sharing.
How many participants and CTUs were represented in the study?
Answer: 23 CTU staff participated, representing staff from 10 of 52 UK registered trials units, as reported in PLOS One (July 30, 2026).
Supporting detail: The article states 24 staff consented and 23 attended focus groups between 01-Jul-2024 and 04-Mar-2025, with demographic responses from 20 participants.
Will the April 28, 2026 UK regulatory changes solve these issues?
Answer: The new regulations address some duplication and codify risk levels, but implementation and local practice change remain necessary, according to PLOS One (July 30, 2026).
Supporting detail: PLOS One (July 30, 2026) notes the legislation reduces duplicate reporting (SUSARs and Annual Safety Reports to MHRA only) but participants still expected ongoing need for clearer guidance and training.
How can AI help with qualitative analysis for safety reporting research?
Answer: AI accelerates coding, quantifies theme frequency, surfaces co-occurrence patterns, and creates auditable summaries for regulators and sponsors.
Supporting detail: The PLOS One study (July 30, 2026) used manual reflexive thematic analysis; AI tools like Evidano replicate that analytic logic while reducing repetitive work and enabling faster knowledge sharing across CTUs.
Conclusion & Next Steps
Answer: Use targeted training, shared CTU resources, and AI-enabled qualitative synthesis to move from defensive, laborious reporting to confident, risk-proportionate safety reporting.
According to PLOS One (published July 30, 2026), trial staff recommended clearer regulator guidance, CTU knowledge-sharing, and mentoring to improve confidence and efficiency.
Next steps for CTU teams include collecting decision logs, building role-specific training modules, and centralising case studies to reduce uncertainty and duplication as the April 28, 2026 regulations are embedded.
