Study summary

This multicenter randomized controlled study will evaluate whether simplified and visually supported procedure-specific information cards improve patients' understanding of informed consent before selected interventional pain procedures. Adult patients scheduled for an eligible procedure will be randomly assigned in a 1:1 ratio to either a control group or an intervention group. All participants will receive the routine verbal explanation and the standard institution-approved informed consent form for the planned procedure. Participants in the intervention group will additionally receive an ethics committee-approved simplified and visually supported information card related to the planned procedure. Participants in the control group will not receive the additional information card. After the information and consent process, patient understanding will be assessed using a standardized teach-back form before the clinical procedure. The study will compare understanding between the two groups.

Read the detailed description

Informed consent is an essential component of patient autonomy and ethical clinical care. However, patients may not fully understand the purpose, potential risks, and alternatives of an interventional procedure, even when routine verbal explanations and written consent forms are provided. Complex medical terminology, limited time, and differences in health literacy may affect patient comprehension. This prospective, multicenter, randomized, parallel-group study will investigate whether adding simplified and visually supported procedure-specific information cards to the standard informed consent process improves patient understanding before selected interventional pain procedures.

The study will include adult patients between 18 and 85 years of age who are scheduled to undergo one of the interventional pain procedures included in the approved protocol. Eligible procedures include piriformis injection, occipital nerve block, transforaminal epidural steroid injection, radiofrequency procedures, and intra-articular shoulder injection. Participants must be able to read, understand, and communicate in Turkish and must provide written informed consent for participation in the study.

Patients with serious cognitive impairment or mental incapacity affecting the consent process, severe hearing or visual loss, an active psychiatric episode affecting perception or expression, or a condition requiring urgent intervention will be excluded. Patients who do not agree to participate will also be excluded.

After eligibility assessment and written consent for study participation, all participants will receive the routine clinical explanation and the standard institution-approved informed consent form for the planned procedure. Participants will then be randomly assigned in a 1:1 ratio to the control group or the intervention group.

Participants in the control group will receive the standard informed consent process alone. Participants in the intervention group will receive the same standard informed consent process plus an ethics committee-approved simplified and visually supported information card specific to the planned procedure. The information card is an additional educational material and does not replace the physician's clinical explanation or the legally required informed consent form.

After completion of the information and consent process and before the planned clinical procedure, patient understanding will be assessed in both groups using a standardized teach-back assessment form. During the teach-back assessment, participants will be asked to explain the relevant information in their own words. The assessment will focus on understanding of the planned procedure and the key information provided during the consent process. The primary analysis will compare the teach-back understanding scores between the control and intervention groups.

The planned target enrollment is 360 participants across the participating centers. The study is planned to be conducted at the following centers: Sanliurfa Education and Research Hospital, Sanliurfa Mehmet Akif Inan Education and Research Hospital, and Ankara Bilkent City Hospital.

The study has received approval from the Harran University Clinical Research Ethics Committee under approval number HÜ-KAEK-2026-00079.

Exclusion criteria

Exclusion Criteria:

  • Age below 18 years or above 85 years.
  • Severe cognitive impairment, mental incapacity, or any condition that prevents reliable understanding of the consent information or completion of the teach-back assessment.
  • Severe hearing or visual impairment that prevents the participant from receiving or understanding the study information, unless adequately corrected.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

  • BehavioralSimplified and Visually Supported Procedure-Specific Information Card

    An ethics committee-approved simplified and visually supported information card specific to the planned interventional pain procedure. This card uses plain language and schematic illustrations to highlight key aspects such as procedure purpose, steps, and potential risks. It is provided to participants in the intervention group as an educational supplement in addition to the standard informed consent process

What researchers measure

Primary outcomes

  1. Patient Understanding of Informed Consent Assessed by Teach-Back

    Patient understanding of the information provided during the informed consent process, assessed using a standardized teach-back form. Participants will be asked to explain the key information about the planned interventional pain procedure in their own words. The primary analysis will compare teach-back understanding between the control group and the intervention group.

    Time frame: Immediately after the informed consent process and before the planned clinical procedure

Start is estimated for Aug 2026; primary completion for Oct 2026, 2 months later.

Of 3,731 non-industry interventional studies with no phase under Pain, half reached primary completion within 10 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 23. This study's planned 2 months is below that.

Counting every sponsor, half of 3,830 studies reached it within 10 months; a quarter within 4 and three quarters within 23.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 19, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
