Design outcomes
Primary
| Measure | Time frame |
|---|---|
| A reduction in pain in the postoperative period is expected. McGill's Reduced Instrument (SF-MPQ) will be used to obtain three different pain indices. This multidimensional instrument assesses pain using descriptors that are selected by the patient. There are 15 descriptors divided into subgroups: sensory (11 descriptors, from 0 to 33 points) and affective (4 descriptors, from 0 to 12 points). Each descriptor receives an intensity rating and can score from 0 to 4 (0 = none, 1 = mild, 2 = moderate and 3 = severe). The pain index of each individual is obtained through the sum of the intensity values of the chosen descriptors. The higher the score, the greater the pain intensity. The maximum possible total value is 45 (0 to 45 points). The SF-MPQ also includes the application of the visual analogue scale (VAS) where the patient signals how his pain has been in the last few days, ranging from no pain to the worst possible pain (0 to 10 points). Present pain intensity (PPI) is also included in the SF-MPQ, ranging from 0 to 5 points, where 0 corresponds to no pain and 5 corresponds to excruciating pain.;A reduction in anxiety in the postoperative period is expected. To measure this outcome, the Hospital Anxiety and Depression Scale – HADS is applied. This scale has 14 items in total that deal with anxiety (HADS–A, 7 items) and depression (HADS–B, 7 items) and appear alternately. The respondent answers seven questions from each subscale that score from 0 to 3 in intensity. Thus, analyzing anxiety and depression in separate groups, the global score for each subscale can reach 21 points. For this study, the classification will be adopted without anxiety and/or without depression, a score from 0 to 8 and with anxiety and/or depression, a score equal to or greater than 9. | — |

|---|---|
| A reduction in the consumption of pain medications is expected. In the postoperative period, the prescription and administration of non-opioid analgesics, opioids, NSAIDs, corticoids, antidepressants, gabapentinoids and other drugs that may be prescribed for pain control are verified. In addition, in the interview with the patient, there is a question in which their knowledge and acceptance of having received pain medication after surgery is checked.;A reduction in catastrophizing is expected. This data will be obtained using the Catastrophic Thoughts Scale about pain, which is made up of thirteen items listed on a Likert Scale ranging from zero (minimum) to four (very intense) points. The scale is divided into three domains: helplessness (items 1 - 5 and 12), magnification (items 6, 7 and 13) and rumination (items 8 - 11). The score is calculated by summing the items. The higher the score, the greater the indication of catastrophic thoughts, being possible to score from 0 to 52.;A reduction in depression is expected. This outcome will be evaluated along with the primary outcome of Anxiety using the Hospital Anxiety and Depression Scale – HADS described in the anxiety item. This scale has 14 items in total that deal with anxiety (HADS–A, 7 items) and depression (HADS–B, 7 items) and appear alternately. The respondent answers seven questions from each subscale that score from 0 to 3 in intensity. Thus, analyzing anxiety and depression in separate groups, the global score for each subscale can reach 21 points. For this study, the classification will be adopted without anxiety and/or without depression, a score from 0 to 8 and with anxiety and/or depression, a score equal to or greater than 9.;It is expected to characterize pain Characteristics of pain by evaluating the location of pain, duration, times of pain improvement and vital signs.;Patients in the intervention group are expected not to report pain-related fear of movement. For this outcome, the patient will be | — |
