Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study endpoint is the patient's postoperative pain score on the NRS and the expressed need for (more) opioids by the patient. Pain will be measured in each patient on the ward on the day after surgery by trained research nurses who are not involved in the postoperative care of that patient and are not aware of the study group in which the patient is included. The patient will be asked to score the enduring pain on an 11 point scale, where 0 indicates no pain and 10 indicates the worst imaginable pain. After the assessment of pain the patients will be asked if they want to have (more) morphine. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary endpoint is knowledge, attitude, anxiety and self-efficacy of the patient. Furthermore, the amount of information a patient needs. Preoperative anxiety has been seen to influence patients to experience more pain after surgery. Furthermore, preoperative information is considered to be an important tool in helping patients to reduce the anxiety associated with surgery and pain. Self-efficacy is defined as a belief that one can effectively perform a given behaviour and the behaviour will result in desired outcomes. Self-efficacy concerns control over specific behaviours necessary in handling pain and pain relief. Anxiety (Fear of surgery questionnaire) and attitude (Patient Barriers questionnaire) will be measured by standard questionnaires. Knowledge and self-efficacy questions will be based on literature and expert opinion. Undergoing surgery is a threatening event for many patients. It is important that patients are adequately prepared prior to surgery. Miller's monitoring-blunting model concerns the processing of health information while some patients want more information (monitors) and some less (blunters). Therefore, monitoring and blunting coping styles were assessed by means of the Threatening Medical Situations Inventory (TMSI). The tertiary endpoint is the patient's pain score on a Verbal Rating Scale (VRS). The VRS contains five expressions: 1. No pain; 2. Little pain; 3. Painful but bearable; 4. Considerable pain; 5. Terrible pain. The first three categories together (no pain, little pain and painful but bearable) are considered bearable and the last two categories together (considerable pain and terrible pain) are deemed unbearable. | — |
