Qualitätssicherung in der postoperativen Schmerztherapie: Erfahrungen einer zertifizierten Kinderchirurgie
No full textDatasets consisting of three pain items (worst pain, movement pain, least pain)
No full textTo assess postoperative pain intensity in adults the Numeric Rating Scale (NRS) is used. This scale has shown acceptable psychometric features,
though its scale properties need further examination. We aimed to evaluate scale properties of the NRS using an item response theory (IRT) approach.
Data from an international postoperative pain registry (QUIPS) was analyzed retrospectively. 346.892 adult patients (age groups: 18-20: 1.6%, 21-30:
6.7%, 31-40: 8.3%, 41-50: 13.2%, 51-60: 17.1%, 61-70: 17.3%, 71-80: 16.4%, 81-90: 3.9%, >90: 0.2%) were included. 55.7 % are female and 38% had
preoperative pain. Three pain items (movement pain, worst pain, least pain) were analyzed using four different IRT-models: partial credit model (PCM),
generalized partial credit model (GPCM), rating scale model (RSM) and graded response model (GRM). Fit indices were compared to decide which model fits
best (lower fit indices indicate a better model fit). Subgroup analyses were done for sex and age groups.unknow
