Qualitative analysis of electronic immunization registry

Evidano6 min read

Researchers and program teams often get structured metrics from EIR pilots but struggle to systematically extract actionable themes from caregiver and provider narratives. This post refracts a July 2, 2026 PLOS ONE pilot of an Electronic Immunization Registry (EIR) in Rajshahi, Bangladesh through the lens of qualitative analysis and shows a repeatable, AI-enabled workflow to convert semi-structured survey responses and open-ended provider notes into themes, segment comparisons, and stakeholder-ready visuals. If you analyze transcripts, survey open-ends, or implementation notes, this guide explains how to reproduce the study’s descriptive insights (n=321) and address common challenges (data quality, PII, multilingual text) using Evidano (Evidano).

Key Takeaways

Evidano is an AI-powered qualitative data analysis platform that speeds PII-safe ingestion, de-identification, AI-assisted coding, and reproducible thematic analysis.

  • A July–September 2024 cross-sectional EIR pilot in Rajshahi City Corporation (n=321: 305 caregivers, 16 HCPs) reported high satisfaction but providers noted intermittent internet and device issues (PLOS ONE, published 2 July 2026).
  • Converting open-ended responses into a coded theme set lets teams quantify barrier vs enabler frequency and produce cross-segment comparisons (caregivers vs HCPs) for program decisions.
  • A two-week reproducible workflow moves raw open-ends to stakeholder-ready briefs using PII redaction, translation harmonization, AI-assisted codebooks, and visual exports.

Fast take: what happened (source)

A cross-sectional descriptive assessment conducted July–September 2024 in Rajshahi City Corporation (RCC) asked caregivers (n=305) and healthcare providers (n=16) about feasibility and acceptability of an EIR introduced in 2019. Respondents reported high satisfaction and easier record access, while providers flagged intermittent internet and device issues. Full study: PLOS ONE.

  • Why researchers care: the paper includes Likert-scale results plus open-ended responses that were summarized but not publicly shared, ideal raw material for deeper qualitative coding and cross-segment analysis.
  • Quick payoff: convert descriptive open-ends into coded themes, quantify theme frequency across caregivers vs HCPs, and produce visual co-occurrence maps for program decisions.

Findings snapshot

July–Sept 2024; Published 2 July 2026Rajshahi City Corporation (urban Bangladesh)n = 321 (305 caregivers; 16 HCPs)87% registrations at EPI centers; high caregiver/HCP satisfaction; registration timeliness ≈88% within 45 days (paper cites similar figures)PLOS ONE

What the study did (plain language)

The study design: cross-sectional purposive sampling of caregivers attending EPI sessions and HCPs using the EIR, using a pretested semi-structured questionnaire with 5‑point Likert items and open-ended fields. Analysis used descriptive statistics (SPSS) and a summary review of open responses, with qualitative answers summarized but not released due to identifiability.

  • Strength for analysts: mixed numeric plus open-ended data are well suited for rapid thematic work and segment comparisons (caregivers vs providers).
  • Limitation to note: purposive sampling and the small HCP n (16) can bias satisfaction estimates; open-ends were summarized descriptively rather than systematically coded.

So what for qualitative researchers & UX teams: primary implications

Researchers (policy / public health)

Researchers should convert the study’s open-ends into a codebook to trace barriers (connectivity, devices) versus enablers (SMS reminders, record access).

Decision value: quantify how often a theme (for example, 'internet issues') appears across caregiver versus HCP segments to inform infrastructure investment.

Program managers & implementers

Program managers should prioritize fixes such as offline-capable forms and device procurement by combining theme frequency with severity tags from provider quotes.

Decision value: generate stakeholder-ready one-page briefs with top-3 user pain points and top-3 suggested fixes supported by verbatim quotes.

UX / Product teams

UX and product teams should map user sentiment to specific workflows (registration, SMS reminders, outreach) and feed prioritized usability fixes into sprint planning.

Decision value: surface co-occurring issues (for example, slow internet plus long registration time) to target bundled improvements.

Ingest & Secure

Ingest and secure: Import survey spreadsheets and inspector notes (CSV, Excel) or upload interview/transcript files directly.

Security: data is encrypted and not used to train third-party models, which is helpful when open-ends may contain sensitive or identifiable content (the PLOS paper withheld raw open-ends for this reason).

Preprocess: de-identify & translate

Preprocess by automatic PII redaction for names and contacts, plus customizable dictionaries for local names and terms.

Translation support: built-in translation and custom dictionary support help analysts harmonize Bangla/English mixed responses before coding.

AI-assisted coding & theme extraction

AI-assisted coding and theme extraction can generate an initial codebook from a seed set of open-ended responses, then apply automated codes to the full corpus.

Iterative refinement: refine codes, split or merge themes, and produce theme frequency tables and cross-segment comparisons (caregivers vs HCPs).

Quantify & visualize

Quantify and visualize with one-click frequency reports, co-occurrence networks, hierarchical code→subcode trees, and downloadable quotes linked to codes for stakeholder decks.

Segment analysis: use cross-segment analysis to show which themes are concentrated among providers versus caregivers (for example, 'device issues' more frequent among HCPs).

Automated follow-ups

Automated follow-ups can deploy AI avatar interviews or SMS follow-ups to target underrepresented segments and reduce time-to-evidence during pilots.

Reproducibility: export reproducible reports and append codebooks for auditability.

2‑week reproducible workflow (from raw open-ends to decisions)

Week 1 objectives: import and prepare data, run PII redaction, harmonize language with translation dictionaries, and create a 10–15 item seed codebook from a purposive sample.

  • Day 1–2: Upload and map columns (respondent type, question id).
  • Day 3–4: Auto-redact PII and run translation (if needed).
  • Day 5–7: Seed-code 10–20% manually and generate an AI-suggested codebook.

Week 2 objectives: scale and synthesize by applying AI-assisted coding to the full corpus, run thematic frequency and cross-segment analysis, generate a co-occurrence network and export top quotes.

  • Day 8–10: Review and refine automated codes; lock the final codebook.
  • Day 11–12: Produce visuals (theme frequencies, co-occurrence map) and segment comparisons (caregiver vs HCP).
  • Day 13–14: Draft a one-page brief with top findings and six verbatim quotes for stakeholders.

FAQ: qualitative analysis of electronic immunization registry responses

Q: Can I quantify themes reliably from short open-ends?

A: Yes, with AI-assisted coding you can standardize synonyms and map short responses to stable codes; always validate with manual review on a random sample.

Q: How do I compare caregivers vs HCPs?

A: Tag each response by respondent type, compute theme frequency and relative prevalence, and use co-occurrence or chi-square tests for larger samples; Evidano automates segmented frequency tables and visual exports.

Q: How should I handle sensitive or identifiable open-ends?

A: De-identify on ingest, store and analyze on encrypted infrastructure, and follow IRB guidance; the PLOS ONE study anonymized data and withheld raw open-ends for identifiability concerns, and Evidano supports PII redaction and secure storage.

Ethics & safeguards (brief)

Ethics guidance: follow local IRB approvals and consent procedures for studies involving human subjects. The PLOS ONE paper anonymized data and withheld raw open-ends for identifiability concerns, mirror that caution when sharing quotes or datasets.

Wrapping up: next steps

Next steps for teams preparing qualitative analysis of EIR pilot data: prioritize reproducible coding, segment comparisons, and secure handling of open-ends. Evidano speeds each step: from PII-safe ingestion and translation to AI-assisted codebooks, thematic frequency, and visual reports, so teams can move from descriptive summaries to actionable program fixes in two weeks.
