Patient-reported pain, satisfaction, adverse effects, and deviations from ambulatory surgery pain medication

Abstract

Abstract Objectives Addressing the challenges of ambulatory surgery involves balancing effective pain relief with minimizing the side effects of pain medication. Due to the heightened risk of opioid abuse, Helsinki University Hospital (Finland) has had a stringent oxycodone prescription policy. This policy prompts an exploration into whether ambulatory surgery patients experience severe post-surgical pain and whether an increase in prescribed opioids would cause elevation in adverse effects. Methods This prospective cohort study, with a 1-week follow-up, included 111 adult ambulatory surgery patients (orthopaedics, urology). The patients documented their pain levels within the first postoperative week (using a numerical rating scale [NRS] of 0–10) and pain medication intake up to two days postoperatively. Furthermore, they completed a questionnaire assessing their satisfaction with pain relief, medication-related adverse effects, and adherence to instructions. Medication intake was cross-referenced with the provided instructions and prescriptions. Results A notable 56% of patients reported experiencing intense pain (NRS ≥5) within a week following surgery. Of these, 52% received a single dose of slow-release oxycodone (5–20 mg) at discharge for use on the night of surgery. Predominantly prescribed pain medications included a combination of paracetamol and codeine (64%) or ibuprofen (62%). Satisfaction rates were high, with 87% expressing satisfaction with pain medication given at hospital discharge and 90% expressing contentment with the prescribed medication. The most common adverse effects were tiredness/grogginess (45%), sleep disturbances (38%), nausea (37%), and constipation (27%). Also, 24% of patients self-reported deviations from medication instructions. A comparison of self-reported and instructed medications revealed that 14% exceeded prescribed dosages, and 28% opted for preparations different from those prescribed. Notably, patients who self-reported deviations from instructions differed from those objectively deviating from instructions. Conclusions Although 56% of patients had intense pain, the majority expressed satisfaction with the provided pain relief. Instances of non-adherence to medication instructions were prevalent, often going unnoticed by the patients themselves.
