Brief Summary

In 2015, more than 50% of surgical procedures were performed in outpatient settings. Successful pain management after outpatient surgery is crucial, and requires a perfect cooperation between caregivers and patients, with clear information on the analgesics use at home. Different strategies to control postoperative pain were adopted by hospitals performing outpatient surgery. However, up to half of patients receive little or no information about the treatment of postoperative pain, and at least one third of them are not able to follow postoperative analgesia instructions. There is a clear unmet need in pain treatment during first 48-72 hours after discharge, with important number of emergency calls and readmissions. The most common causes of rescue calls after outpatient surgery are uncontrolled pain and questions about medications or post-operative care. Structured education interventions using psychological techniques to enhance engagement and behavior were found to be beneficial for better acute pain management in outpatient settings after orthopedic surgery. We hypothesize that an educational intervention based on the rational perception of postoperative pain and discomfort, and the proper use of analgesics would improve the quality of pain management at home and reduce analgesics-related side effects. Principal objective of this study is to evaluate the impact of a preoperative educational intervention on effectiveness of postoperative pain self-management in outpatient settings compared to the current practice. Secondary objectives are to evaluate the prevalence of analgesics use and the incidence of severe pain episodes, as well as side effects. The occurrence of neurological pain, quality of sleep, and patient's comfort will be evaluated at 30th day after surgery.

Outcome Measures

Primary Outcomes (1)

• Time-weighted sum of Pain Relief - Total Pain Relief (TOTPAR) during 5 postoperative days

  TOTPAR is a global score based on relief of pain. A numerical scale has at its left end the words "no relief = 0" and at its right end "complete relief = 100%". The pain relief score is calculated using the area under the curve for a defined period of time. TOTPAR is also expressed as a percentage of the maximum TOTPAR that would be achieved by treatment that would provide complete relief during the observation period. In order to measure this area under the curve, at least 3 measurements per day will have to be reported in the patient diary.

  Day 5

Secondary Outcomes (7)

• Time-weighted sum of Pain Relief - Total Pain Relief (TOTPAR)

  At Day 10, Day 20 and Day 30 with the initial point at Day 5

• Type, number and doses of prescribed analgesics

  At Day 0, Day 1, Day 2, Day 3, Day 4, Day 5, Day 10, Day 20 and Day 30.

• Incidence of severe pain (≥ 7 out of 10).

  From day 0 to the end of stidy (Day 30)

• Incidence of side effects (nausea / vomiting / gastralgia / dizziness / concentration disorder / somnolence / constipation, other).

  From day 0 to the end of stidy (Day 30)

• Prevalence of neuropathic pain assessed by using the DN4 scale.

  At Day 30

Study Arms (2)

Patients with a therapeutic educational intervention

EXPERIMENTAL

Arm 1 : Interventional group: A therapeutic educational intervention is performed following pre-anesthesia assessment

Behavioral: Educational intervention

Patients without therapeutic educational intervention

ACTIVE COMPARATOR

Arm 2 : Control group: standard information on pain is performed following pre anesthesia assessment

Behavioral: Standard information

Interventions

Educational intervention BEHAVIORAL

During the usual pre-anesthesia assessment (performed between D-30 and D0 of the intervention), the anesthesiologist will deliver to the intervention group patient oral and visual information on: * the numerical scale of pain ranging from 0 to 10 with examples of perceptions corresponding to each level of the scale (calibration) * nature of postoperative pain (inflammatory character, dynamic over time) * average pain level incurred by the intervention * the difference between anti-inflammatory and opioid analgesics * principles of systematic treatment and pain anticipation * principles of overdose and side effects prevention This information is standardized and delivered orally, accompanied by a visual support (patient diary), which will be given to the patient upon discharge from the hospital

Patients with a therapeutic educational intervention

Standard information BEHAVIORAL

Standard information on pain For patients in the control group the standardized information is based on the SG/DGM/DSS 1/41-2010 scheme of the AFSSAPS-CFETD repository.

Patients without therapeutic educational intervention
