Characterisation of pragmatic postoperative PAin Trajectories over seven days and their association with CHronicity after 3 months: a prospective, pilot cohort study (PATCH study).

BACKGROUND: Reliable outcome measurement providing information both on early and late postoperative pain outcomes are still lacking. The purpose of this study was: 1) to characterise postoperative pain trajectories according to an innovative pragmatic concept: ideal pain trajectory (rapid and sustained pain relief) vs non-ideal pain trajectories (late, transient, or no pain relief); and 2) to assess the incidence of persistent post-surgical pain (PPSP) and the potential association between non-ideal pain trajectories and PPSP. METHODS: This prospective observational pilot cohort study was performed from March until June 2016. A total of 344 patients undergoing major general surgery were invited to complete a self-assessment of pain intensity using numerical rating scale (NRS; 0 = no pain to 10 = worst pain) from day 1 until day 7 after surgery, in order to establish their pain trajectory. Three months after surgery, patients were screened for PPSP. RESULTS: Rest pain score was analysed in 308 participants. Among them, 210 (68% - 95% CI: 63-73) had an "ideal" pain trajectory, while 98 (32% - 95% CI: 27-37) had "non-ideal" pain trajectories. Three months after surgery, 31% (95% CI: 26-37) reported PPSP. Multivariable analysis showed that "non-ideal" pain trajectories [OR 2.25; (95% CI: 1.26-4.01) P = 0.006] were significantly associated with PPSP. CONCLUSIONS: The present study proposes an innovative pragmatic concept of postoperative pain trajectories: ideal vs non-ideal pain trajectories, providing information both on acute postoperative pain resolution and early identification patients at risk for developing PPSP.

[Standards, Options and Recommendations 2005 for a good practice in enteral nutrition in oncology (summary report.)]. / Recommandations pour la pratique clinique: Standards, Options et Recommandations 2005. Bonnes pratiques pour la prise en charge diététique en cancérologie: la nutrition entérale (rapport abrégé). Validation du rapport original: avril 2005.

CONTEXT: The "Standards, Options and Recommendations" (SOR) project, which started in 1993, is a collaboration between the French Federation of Cancer Centers (FNCLCC), the 20 French Regional Cancer Centers, and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. OBJECTIVE: To develop good practice guidelines for a good practice of enteral nutrition in oncology, in collaboration with three French learned societies involved in this area. METHOD: The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts who define the CPGs according to the definitions of the Standards, Options and Recommendations project. Once the guideline has been defined, the document is submitted for review by independent reviewers. RESULTS: The good practices suggested in the document approach seven topics: indications and counter-indications, conditions of the installation of the enteral nutrition, monitoring, prevention of complications, education of the patient, specificities of enteral nutrition in children and at home. In the setting of enteral nutrition, feeding tubes, type of insertion, enteral nutrition products, material and techniques of administration are described as well as the criteria permitting their selection.
