Background and Goal of Study: The management of acute postoperative pain is one of the major concerns of the Anesthesiologist. The increasing use of multimodal analgesia protocols, patient controlled analgesia or locoregional analgesia leads to better pain control 1. The objective of this study was to evaluate the records of the Acute Pain Service (APS) of the Divino Espírito Santo Hospital (DESH) - Ponta Delgada during the year 2015, in order to evaluate the following: 1) to know the demographic characteristics of the patients; 2) number of consultations; 3) the most prescribed protocols and analgesic modalities.
Materials and Methods: Retrospective study using an Excel database of the APS records for the year 2015. 
Results and Discussion: 
1) During the year 2015 the Acute Pain Unit followed a total of 1123 patients, of which 765 were female (68.1%) and 358 male (31.9%). Regarding the age group, 7 patients were between 1 and 12 years old, 680 between 12 and 60 years old, 171 between 60 and 75 years old, and 83 patients over 75 years old (in 182 cases this information was not registered).
2) A total of 2934 consultations were performed, of which 256 patients required only one observation and 438 had two observations. In 429 cases, 3 or more observations were required by the APS (17 patients had 10 or more consultations).
3) Of the 1123 protocols instituted in the postoperative period it was concluded that: 307 corresponded to conventional analgesia (intravenous multimodal), 796 to epidural analgesia, 10 to patient controlled analgesia (PCA) and 10 to patient controlled epidural analgesia (PCEA). 
Conclusions: Clinical audits are important tools to know the quality of health services provided to patients.1 From the analysis performed it was possible to draw the following conclusions: 
· In DESH the majority of patients followed by APS were female (68.1%) and aged between 12 and 60 years;
· In 429 cases (38.2%) 3 or more follow-up visits were required for effective pain control;
· Epidural analgesia was the most used analgesic modality of the postoperative period, corresponding to 796 (70.9%) of the cases.
