Pain Medication After Ambulatory Surgery

After informed consent, all patients operated as ambulatory surgery patients during the study period are given a letter interview for pain, pain medication and symptom follow up. They are also given a return envelope (with paid postal fee) to return the interview. Based on the results of the first interview phase, our pain medication practice is reconsidered by anesthetists and surgeons to create a standard operating protocol for pain medication. The standard operating protocol is informed to personnel. Then, patient interview phase is repeated for another 3 months. Then, investigators continue with a pilot study on using a mobile phone app in evaluating patients pain, sufficient pain medication and adverse effects. All patient with informed consent, suitable mobile phone, and willing to use it for reporting pain for hospital personnel are contacted via the mobile app. Other patients operated during that study period are interviewed by either letter interview or phone interview. Investigators try to estimate whether mobile apps are suitable for pain and medication follow-up.
