A clinical thesis involves a lot more documentation than most medical students anticipate when they start. It is not just about the final thesis manuscript — it is about maintaining a complete set of records from the first meeting with your guide to the submission of the final bound copy.

This guide organizes all the documentation you need into four phases: Pre-study, Data Collection, Analysis, and Submission. Use it as a living checklist throughout your thesis period.

Why Documentation Matters Beyond the Thesis Itself

Poor documentation is the most common reason for thesis-related complications at the viva stage. Examiners regularly ask for consent forms, ethical approvals, and raw data sheets. If you cannot produce them, your methodology is in question regardless of how good your results are.

Proper documentation also protects you. If a patient outcome is later queried, or if your data is audited by your institution, your records are your defense.

Phase 1: Pre-Study Documentation

1

Before You Enroll Your First Patient

  • Protocol document — The full study protocol approved by your guide and department head. Includes objectives, design, inclusion/exclusion criteria, sample size calculation, and statistical plan.
  • IEC/IRB approval letter — Your institutional ethics committee approval. Keep both the original and a signed copy.
  • Patient Information Sheet (PIS) — The document explaining the study to patients in plain language, in English and the local language.
  • Informed Consent Form (ICF) — The signed consent document. Keep one copy with the patient and one in your study files.
  • CRF (Case Record Form) — Approved version with version number and date.
  • Subject Identification Log — Secure document linking Study IDs to patient identities. Stored separately from all other study documents.

Phase 2: Data Collection Documentation

2

During the Study Period

  • Signed consent forms — One per patient, filed by Study ID.
  • Completed CRFs — One per patient per visit. No blanks. Errors crossed out with a single line, initialed, and dated.
  • Patient enrollment log — Updated after every patient interaction. Shows screening, enrollment, active, and exit dates.
  • Data sheet (master chart) — The analysis-ready spreadsheet. Backed up weekly, at minimum.
  • Protocol deviation log — Any instance where the protocol was not followed exactly, with reason and corrective action.
  • Serious Adverse Event (SAE) reports — Required if any serious adverse event occurs. Filed with the IEC within the mandated timeframe.

Phase 3: Analysis Documentation

3

After Data Collection Is Complete

  • Locked dataset — The final, database-locked version of your data sheet. Once locked, no changes without formal documentation.
  • Statistical analysis plan (SAP) — Written before you run any analysis. Describes which tests you will use and why. Prevents data dredging accusations.
  • Statistician letter or certificate — If you used an external statistician, their letter confirming what they analyzed and the methods used.
  • Analysis output files — SPSS output files, R scripts, or Stata do-files. Keep these; do not just keep screenshots.
  • Codebook — Final version defining every variable in your locked dataset.
Database lock: Before statistical analysis, formally "lock" your dataset by saving a password-protected read-only copy. Date and sign the lock. Any analysis uses the locked version — the data sheet is no longer editable after lock unless a formal amendment is logged.

Phase 4: Submission Documentation

4

At and After Thesis Submission

  • Thesis manuscript — All drafts, with guide and co-guide signatures on the final version.
  • Plagiarism report — Turnitin or iThenticate report as required by your university.
  • Publication records — If any work was published or presented, attach the publication/presentation certificate.
  • Data archiving plan — Where your CRFs, consent forms, and dataset will be stored post-submission and for how long.

Organising Your Physical and Digital Files

Create a folder structure that mirrors the four phases above. In your digital folders: Pre-study, Data-Collection, Analysis, Submission. In your physical files, use labelled binders in the same order. Store physical documents in a locked cabinet accessible only to you and your guide.

Cloud storage (Google Drive, OneDrive) is acceptable for non-patient-identified documents like the protocol and CRF blank templates. Patient-identified documents — consent forms, CRFs — must be stored per your institution's data privacy policy.

ThesisLog: One Place for All Your Thesis Data

ThesisLog organizes your patient data, CRFs, and enrollment log in a single, secure platform — with export-ready output for each phase of your thesis.
