Lack of adequate postoperative pain relief has negative effects on patient outcome and satisfaction. Nowadays pain continues being undertreated all over the world. Incidence of moderate to severe pain is between 30 to 80[%] of postoperative patients. An Acute Pain Program (APP) is strongly recommended in institutions and must be based on clinical guidelines with the best evidence available. Objectives: Evaluation of the APP of Clínica Alemana regarding the efficacy and safety of pain management and patients' opinion about their pain experience and care provided by the pain team and nurses. Methods: We reviewed the electronic data of all patients treated by the APP between December 2010 and September 2011 (993 patients). Also a group of 163 patients was interviewed with a survey of nine questions by blind investigators. Results: Mean age was 51.4 ± 18 years; 51[%] female and 49[%] male. Patients had acute postoperative pain (93[%]) and non-surgical acute pain (7[%]). The mean stay in APP control was 2.6 ± 1.19 days. Analgesic techniques were multimodal analgesia: iv PCA 46[%], epidural catheters 35[%] and perineural catheters 18 [%]. Morphine was the more used opioid (63.8[%]). All patients were treated with 1 to 3 non opioid analgesics. Adjuvant medication was used in 11[%] of the patients. The mean pain intensity registered the first day was 1.4 at rest and 3.3 dynamic (0-10 scale) and these values decreased to 0.86 and 2.5 respectively on the day of discharge. Almost all values were in range of mild pain (0-3). No complications occurred related to analgesia methods. Survey results: It is clear that the vast majority of patients assigned great importance to pain control. The memory of the pain experience was 41[%] mild pain (0-3), 30[%] moderate pain (4-6) and 29[%] severe pain (7-10). Other symptoms associated were drowsiness, insomnia and nausea. Team Pain was assessed with the maximum score in quality care by the majority of the respondents and also more than 90[%] of them were comfortable with the analgesic techniques used. Finally the average assessment received for comprehensive care of acute pain was 8.4 (maximum 10). Some differences were observed between registered pain score and patient's pain memory and between male and women in the opinion survey. Conclusion: These results support that our APP is efficient and safe in acute pain patients, who were in general very satisfied with the care provided.
