The coverage for acupuncture for chronic lower back or knee pain by the statutory health insurance was introduced in 2007. The aim of this study was to investigate characteristics of patients and providers of acupuncture and temporal and regional trends in the utilization of acupuncture. This retrospective observational study used anonymized statutory health insurance claims data from a sample of roughly four million subjects. The sample is representative of the German population regarding age and gender in 2013. Lower back pain was the most common coded indication (86%) for billing acupuncture. Women were more often treated with acupuncture than men; the mean age was 61.1 years. For 63% acupuncture was billed in 2014 for the first time, 37% already had an acupuncture treatment in 2012 or 2013. Premature termination (<6 sessions) was observed in 14% of all insurants receiving acupuncture for the first time in 2014 for knee pain and in 21% of those with back pain. Overall there was a statistically significant decrease in the utilization of acupuncture from 2008 to 2015. Regional differences between East and West Germany and city states were observed. Half of all acupuncture treatments in 2014 were provided by 11% of all physicians who billed acupuncture at least once. Higher utilization of acupuncture by women reflects the epidemiology of back and knee pain and their preference for alternative complementary medicine. On the one hand, the large proportion of patients treated repeatedly with acupuncture suggests perceived benefits. On the other hand, provision of acupuncture services is decreasing continuously and a relevant proportion of subjects are terminating treatment prematurely.
