What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Pain on Movement Score

    Mean pain on movement score was defined as the mean of the pain on movement score over Days 1 to 5 post-surgery. Pain experienced by participant during passive flexion through 90 degree and passive abduction through 30 degree at operated hip joint was evaluated on a scale of 0 to 10 where, 0= no pain and 10= worst possible pain.

    Measured: Every 12 hours from Day 1 to Day 5 post-surgery

Secondary outcomes (6)
  1. Mean Daily Pain Score

    Mean daily pain score was defined as the mean of daily pain score over Days 1 to 7 and Days 8 to 14 post-surgery. Daily Pain Rating Scale (DPRS): participant rated 11-point Likert scale ranging from 0 (no pain) to 10 (worst possible pain) during past 24-hour period. Higher score indicates greater level of pain.

    Measured: Day 1 to Day 7, Day 8 to Day 14 post-surgery

  2. Mean Daily Sleep Interference Score

    Mean daily sleep interference score was defined as the mean of daily sleep interference numeric rating scale (NRS) score over Days 1 to 5 post-surgery. Daily Sleep Interference Scale (DSIS): participant rated pain during past 24-hour period on NRS ranging from 0 (pain does not interfere with sleep) to 10 (pain completely interferes with sleep). Higher score indicates a greater level of sleep disturbance. Self-assessment performed daily on awakening prior to taking study medication.

    Measured: Day 1 to Day 5 post-surgery

  3. Mean Anxiety Visual Analogue Scale (A-VAS)

    Mean anxiety visual analogue scale (VAS) was defined as the mean of VAS score on the day of surgery and over Days 1 to 5 post-surgery. Participants measured their degree of anxiety over past 24 hours on a VAS of 0 to 100, where 0 = not at all anxious to 100 = extremely anxious.

    Measured: Day 0 to Day 5 post-surgery

  4. Time to Mobilization After Surgery

    Participant was encouraged each day (from Day 3) to attempt walking depending upon the degree of pain on standing. The first day on which the participant was able to walk for 5 steps was the day of mobilization. Median time to mobilization (in hours) was calculated till the day of mobilization.

    Measured: Day 1 to Day 5 post-surgery

  5. Number of Participants With Rescue Medication Usage

    Rescue medications were used for participants with moderate or severe resting pain. Fentanyl injection (25 microgram [mcg] intravenous bolus to a maximum dose of 3 milliliter/day), paracetamol tablet (15 milligram/kilogram orally to a maximum dose of 45 milligram/kilogram/day) were used as rescue medications.

    Measured: Day 0 to Day 6 post-surgery

  6. Number of Participants With Neuropathic Pain

    ID Pain questionnaire was used to assess neuropathic pain. 6 items questionnaire, did pain feel like: (1)pins and needles (2)hot/burning (3)numb (4)electrical shocks (5)is pain made worse with touch of clothing or bed sheets (6)is pain limited to your joints. "Yes" response to questions 1-5 were scored as 1, while a "yes" response to question 6 was scored as -1. "No" response were scored as 0. Overall score range -1 to 5.Higher score more indicative of pain with a neuropathic component. Number of participants with score 2 or more (which indicated nerve pain) were reported.

    Measured: Day 90, Day 180 post-surgery

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

What does the primary outcome measure?

Mean Pain on Movement Score (time frame: Every 12 hours from Day 1 to Day 5 post-surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
