The recommendations of the PROSPECT Working Group are graded A – D, based on the level of evidence from the studies, which is in accordance with the Oxford Centre for Evidence – Based Medicine (CEBM website accessed Dec 2003, Sackett 2000). In the context of PROSPECT,Recommendations based on procedure – specific evidence are grade A (randomiZed clinical trials), those based on transferable evidence are grade B (randomiZed clinical trials) or grade C (retrospective studies or case series) and those based on clinical practice are grade D. (Click here for further information on levels of evidence and grades of recommendation).

Οι προτεινόμενες Συστάσεις της Ομάδας Εργασίας της PROSPECT “βαθμολογούνται” ανάλογα με το συνολικό επίπεδο επιστημονικής τεκμηρίωσης – απόδειξης (Οverall Level of Evidence – LoE), στο οποίο και στηρίζονται και το οποίο καθορίζεται από την ποιότητα και τις πηγές από τις οποίες προέρχονται οι επιστημονικές πληροφορίες (Levels of Εvidence and Grades of Recommendation in PROSPECT reviews from 2006).

PROSPECT provides clinicians with supporting arguments for and against the use of various interventions in postoperative pain based on published evidence and expert opinion. Clinicians must make judgements based upon the clinical circumstances and local regulations. At all times, local prescribing information for the drugs referred to must be consulted.The following pre-, intra- and postoperative interventions have been evaluated for the management of postoperative pain following herniorraphy:
