Video-Based Versus Numerical Pain Assessment in Postoperative Patients: A Pilot Study

NCT07051304 | Completed

• 1 other identifier: pain assesment with videos
• Study Type: observational
• Target: 240
• Locations: 1 country
• Sites: 1

Brief Summary

The goal of this observational pilot study is to evaluate whether video-based visual scenarios representing different levels of pain are preferred over the traditional Numerical Rating Scale (NRS) by postoperative patients. The study also investigates the clarity and interpretability of both methods and examines the level of agreement between the selected video and the reported NRS score.

Outcome Measures

Primary Outcomes (1)

• Patient Preference Between Video-Based and Numerical Rating Scale (NRS) Pain Assessment Methods

  This outcome evaluates which pain assessment method patients prefer after being exposed to both the video-based pain expression scenarios and the traditional NRS scale. Patients will be asked, "Which method did you prefer to express your pain?" and their answers (Video or NRS) will be recorded. The result will be reported as the proportion of participants preferring each method.

  Immediately after postoperative evaluation in the recovery unit (within 1 hour after surgery)

Secondary Outcomes (3)

• Concordance Between Selected Video and Reported NRS Score

  Immediately after postoperative evaluation

• Perceived Clarity of Pain Assessment Methods

  Immediately after postoperative evaluation

• Influence of Demographics on Method Preference

  Immediately after postoperative evaluation

Interventions

numerical rating scale OTHER

The Numerical Rating Scale (NRS) is a standardized, self-reported pain assessment tool in which patients are asked to rate their pain intensity on a scale from 0 to 10. 0 represents "no pain" 10 represents "the worst pain imaginable"

Video-Based Pain Expression Scenarios OTHER

This novel pain assessment method involves showing postoperative patients a set of pre-recorded video scenarios that visually represent different levels of pain intensity. The videos are 8 seconds long and were created using AI-generated scripts and VEO-3 software. Each scenario corresponds to a specific Numerical Rating Scale (NRS) range (1-2, 3-4, 5-6, 7-8, 9-10) and is portrayed by actors matched to the patient's age group and gender (18-44, 45-65, \>65 years; male and female versions available). Participants are asked to watch the full video set and select the one that best represents their current postoperative pain experience. This intervention is designed to offer a visual and contextual method of pain expression, particularly beneficial for patients who have difficulty understanding or using abstract numerical scales.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

The study population consists of adult postoperative patients (aged 18 years and older) who are recovering in the recovery room following any type of surgery. Participants must be conscious, cooperative, and capable of evaluating and expressing their pain using both video-based scenarios and the Numerical Rating Scale (NRS). All participants will provide written informed consent prior to participation. The population will include a range of age and gender groups to allow evaluation of method preference across demographic subgroups.

You may qualify if:

• Age ≥ 18 years
• Undergoing any type of surgery
• Admitted to the postoperative recovery unit (PACU) in stable condition
• Able to understand and respond to questions
• Provide written informed consent (ICF)

You may not qualify if:

• Age \< 18 years
• Refusal or inability to provide informed consent
• Visual impairment or blindness
• Impaired consciousness or cognitive inability to complete the questionnaire
• History of psychiatric illness
• Planned postoperative ICU admission
• Patients undergoing surgery for intracranial mass
• History of seizure disorders
