[Knowledge assessment of the coding using CSARR nomenclature, two years after its establishment]

Abstract

Background: French post-acute care and rehabilitation facilities describe and code their activity through the Program for Medicalization of Information Systems (PMSI). A new specific catalogue of rehabilitation procedures (CSARR) has been implemented to code rehabilitation acts since 2013. This study aimed to assess the coherence of the coding of the rehabilitation acts using the CSARR two years after its establishment through the analyze of 3 main items regarding patients and therapists.

Methods: We analyzed the use of CSARR for coding rehabilitation acts from the PMSI national database for post-acute care and rehabilitation, in 2015. Analyses were made on specific items characterizing rehabilitation acts: "number of patients", "type of therapists" and "number of therapists".

Results: There were 72,014,731 rehabilitation acts coded in 2015 using CSARR nomenclature; 86% were individual rehabilitation acts. All acts of CSARR, except one, were used to describe rehabilitation activities. Physiotherapists coded the majority of rehabilitation acts (47%), then nurses (14%). Coding errors were identified as the "number of patients", coded with more than one patient for individual acts (13% of the acts) or with less than 2 patients for groups (6% of the acts), or the "number of therapists" coded with only one therapist for rehabilitation acts requiring several professionals.

Conclusion: This first assessment indicated a good level of appropriation of the CSARR coding rules in the national PMSI database by post-acute care and rehabilitation facilities. However, a simplification of this catalogue and therapist training could increase the quality of the rehabilitation data.
