Correlation between obesity and manual lymphatic drainage in Germany – a retrospective analysis from 2008 to 2016
Abstract
Summary: Backgrounds: Costs for manual lymphatic drainage (MLD) paid by the Statutory Health Insurances (SHI) have increased disproportionately in Germany in the last decade. There is no obvious reason that this increase is due to an increasing number of patients with lymph edema. We therefore assume that there are large numbers of patients with obesity and obesity-associated dependency syndrome who drive the cost of MLD and did a retrospective analysis of the correlation between hospitalization rates for lymph edema and obesity and MLD prescription rates in outpatients. Patients and methods: Roughly 90 % of the German population is insured by the Statutory Health Insurance. From its reports we extracted data regarding costs and numbers of MLD session prescribed annually. Hospitalization rates for lymph edema (codes I89.*, I97.2 and Q82.0) and for obesity (ICD E66.*) were provided by the Federal Statistical Office after a specific remote analyses. Results: In the years 2008 to 2016, the MLD prescriptions in the individual federal states increased by + 43.5 % in Berlin to + 109.3 % in Mecklenburg-Western Pomerania. Number of hospitalizations with the principal diagnosis (condition, which caused the admission) hereditary and postmastectomy lymph edema are low and decreased in most federal states. Number of hospitalizations with the additional diagnosis (conditions that coexist at the time of admission or develop subsequently) obesity increased with a range from + 4.8 % in Baden-Württemberg to + 86.4 % in Mecklenburg-Western Pomerania. The correlation between the increase in prescribed MLD in the individual federal state and the increase in hospitalization rates per 1000 inhabitants of cases with obesity is greater (R2 0.4696) than with lymph edema (R2 0.0987). Conclusions: Our analysis is in line with the hypothesis that there is a correlation between the increasing prescription rate of MLD and the increasing burden of obesity in Germany.
