title: [Validation of the Patient Classification System Rehabilitee-Management-Categories (RMK) in Patients with Chronic Back Pain in Regular Medical Treatment].
abstract: OBJECTIVE
  The Rehabilitee-Management-Categories (RMK) have been developed by the Charite - University Medicine Berlin for 10 years. A content- and time-stable classification approach should support health care providers to offer therapy standards that are better adjusted to the needs of patients. At the same time, stability means for healthcare payers that the admission management to clinics with specialised services could be optimized.
  
  
  METHODS
  The stability of the RMK classification was tested with the help of latent class analysis (LCA) in independent samples. The data sets are taken from 3 different studies carried out from 2006 to 2011. Only patients with chronic back pain (M40-M54) who were in regular medical treatment provided by the German Pension Fund were included.
  
  
  RESULTS
  A statistically stable 4-class solution was found in all samples. Kappa-coefficients from 0.605 to 0.72 showed a good consistence of the RMK-algorithm from the first LCA with the respective latent class analyses.
  
  
  CONCLUSIONS
  The RMK-approach offers possible uses for both healthcare providers and healthcare payers by assessing the need of treatments according to the ICF approach. Among other things, this approach can be used to fulfil the quality guideline in a differing way.
