[Development of a guideline for rehabilitation of patients with low back pain-- phase 2: analysis of data of the classification of therapeutic procedures]. / Leitlinienentwicklung in der Rehabilitation bei Rückenschmerzpatienten--Phase 2: Ergebnisse einer Analyse von KTL-Daten.

Initiated by the Federal Insurance Institute for Salaried Employees (BfA, Bundesversicherungsanstalt für Angestellte), the project is aimed at developing an evidence-based guideline for rehabilitation of patients with low back pain (LBP). Guideline development will be based on a systematic review of the literature, an analysis of the treatment procedures currently employed in rehabilitation, inclusion of the patients' perspectives as well as consultation of experts' panels of clinically experienced physicians and therapists. Formulation of the guideline will then be carried out in a structured consensus building process. This article is focused on analysing the present situation with regard to the treatments received by patients insured by the BfA, using data from routine documentation according to the Classification of Therapeutic Procedures (KTL, Klassifikation Therapeutischer Leistungen). The analysis is intended to provide indications of a basic need to implement a common guideline as well as, simultaneously, to explore possible deficits in present treatment practices, hence to define priorities requiring special attention in the framework of guideline development. As a result of a systematic literature review, the KTL-defined therapeutic procedures that had emerged as relevant in the rehabilitation of LBP patients were aggregated into so-called therapeutic modules which then formed the basis of the analysis. In all, more than 46,000 KTL-data of 2438 patients with a diagnosis of "low back pain" (M54.5 ICD-10) were included. In the rehab centres investigated, rehabilitation of patients with LBP follows a multidimensional, multiprofessional therapeutic strategy. More than 90 % of all patients receive treatments from the modules "medical training therapy", "health education", "physiotherapy", and "physical therapy". Treatments provided to a majority of the patients are massage (78 %), electrotherapy (67 %) as well as psychotherapy (68 %). Women more frequently than men receive therapies belonging to the "psychological treatments" and "occupational therapies" modules; younger patients receive more of the "training therapies", and more often. When treatments are compared across centres, a large variability in the therapeutic procedures provided becomes apparent. This high degree of variability suggests that development and implementation of a common clinical practice guideline for rehabilitation of patients with chronic low back pain should receive priority attention.
