RESUMEN
OBJECTIVES: To investigate the influence of an Acute Pain Service (APS) on the incidence of chronic postsurgical pain (CPSP). To assess the acute pain intensity as a risk factor for CPSP. The impact of an APS on the incidence of CPSP has not yet been studied. METHODS: Retrospective questionnaire given to randomized cohorts study, performed in two hospitals - Hospital A with an APS and Hospital B without such service. 1444 patients underwent eight different surgical procedures in both hospitals within one year, 175 patients from each hospital were randomized. RESULTS: 208 questionnaires were analysed. There was a significant difference in acute pain intensity in the first 24 hours after surgery. The difference of CPSP incidence between hospitals was not significant (Hospital A nine patients (8.6 %), Hospital B sixteen patients (15.5 %). The patients with CPSP experienced significantly more intensive pain in the first 24 hours and at discharge than patients without CPSP regardless of the hospital. CONCLUSION: The study did not demonstrate the incidence of CPSP was lower in the hospital with an APS despite the lower postoperative pain scores. However there was a noticeable trend toward higher incidence of CPSP in the hospital without an APS. The study demonstrated that APS decreases intensity of an acute postoperative pain and acute pain intensity is a risk factor for CPSP incidence (Tab. 5, Ref. 27).
