[10-year development of spine surgery in Germany - An analysis of health insurance funds data from 2005 to 2014].

Abstract:

BACKGROUND:Analysis of the regional development of spine surgery in Germany between 2005 and 2014. MATERIAL AND METHODS:A secondary data analysis of inpatient data from the Scientific Institute of the AOK (WIdO) was carried out for the period 2005 to 2014. The number of spinal procedures was determined on the basis of 14 defined intervention groups (procedures according to OPS codes). The regional numbers of spine surgery procedures in the 402 districts in Germany and the regional age- and gender-standardised distribution are displayed as healthcare utilisation charts. RESULTS:796,870 AOK-insured individuals received inpatient spinal surgery during the observation period. The relative increase in the 10-year period was 82%, with 51,053 interventions in 2005 and 91,971 interventions in 2014. The increase in spine surgery cases occurred mainly between 2005 and 2011. An increase in the number of operations was observed in all intervention groups except "excision of intervertebral discs and bones". It was different in different spinal procedures, with the greatest increases in "bone decompression" (280% increase). Regional differences were found in all intervention groups. In 2014, the number of interventions varied between 109 and 729 interventions per 100,000 AOK-insured individuals in the districts. CONCLUSION:The significant increases of more than 80% in 10 years cannot be explained solely by sociodemographic changes. The pronounced regional differences alone do not allow firm conclusions on the existence of regional underuse, overuse or misuse. The results, however, emphasise the need for further health services research on the quality of the medical indication and the determinants of regional variation. HINTERGRUND:Analyse der regionalen zeitlichen Entwicklung von Wirbelsäulenoperationen in Deutschland zwischen 2005 und 2014. MATERIAL UND METHODEN:Es erfolgte eine Sekundärdatenanalyse stationärer Daten des Wissenschaftlichen Instituts der AOK (WIdO) für den Zeitraum 2005 bis 2014. Für 14 definierte Eingriffsgruppen wurde die Zahl operierter Patienten (Eingriffsfälle) sowie der durchgeführten Wirbelsäulenoperationen (Prozeduren anhand OPS-Code) ermittelt. Die regionale Versorgungshäufigkeit in den 402 Kreisen in Deutschland sowie die alters- und geschlechtsstandardisierte Verteilung wird in Versorgungskarten dargestellt. ERGEBNISSE:Im Beobachtungszeitraum erfolgten 796 870 stationäre Behandlungsfälle mit Wirbelsäulenoperation bei AOK-Versicherten. Die relative Zunahme im 10-Jahres-Zeitraum betrug 82% von 51 053 Eingriffen 2005 auf 91 971 Eingriffe 2014. Die Fallzahlerhöhung fand insbesondere 2005 bis 2011 statt und betraf alle Eingriffsgruppen außer „Exzision von Bandscheiben und Knochen“. Sie war unterschiedlich stark ausgeprägt mit stärksten Zuwächsen bei der „Knöchernen Dekompression“ (280% Anstieg). Bei allen Eingriffsgruppen fanden sich regionale Unterschiede. 2014 betrug die Schwankung zwischen 109 und 729 Eingriffen je 100 000 AOK-Versicherte zwischen den Kreisen. SCHLUSSFOLGERUNG:Die deutlichen Anstiege um > 80% in 10 Jahren sind soziodemografisch nicht plausibel erklärbar. Die dargestellten, ausgeprägten regionalen Unterschiede allein erlauben keine abschließenden Rückschlüsse zum Vorliegen einer regionalen Unter-, Über- oder Fehlversorgung. Sie unterstreichen jedoch die Notwendigkeit weiterführender versorgungsepidemiologischer Studien zur Indikationsqualität und zu Determinanten der regionalen Variation von Eingriffszahlen.
