BACKGROUND Quality profiling is practiced at the TCM hospital Bad Kötzting since its establishment 25 years ago. The profiling comprises assessment of treatment effectiveness andsafety, structural features, staff qualification as well as diagnostic and therapeutic processes. Findings regarding patients, intervention and outcome profiles are presented by appropriate examples. METHODS Data of each in-patient were systematically collected by physicians and via self-reports at admission, discharge and follow-up. Over the years the system was adjusted several times resulting in a data pool of about 19,000 in-patients by end of 2014. RESULTS Patients are 52 years old on average, 70% are female, and suffering from the main complaint since 7 years (median). The diagnostic spectrum changed over the years according to the development towards a psychosomatic focus. For TCM acupuncture therapy 222 different acupoints were used in 7.7 different localisations on average per individual treatment. The mean intensity of the main complaint decreased clinically relevant (Cohen's d = 1.11 at discharge and 0.93 at follow-up). After the hospital stay the number of days of sick leave declined from 51.3 days by 40% per patient and year. Depressive disorders as most common mental illness decreased significantly decreased significantly at discharge (ICD symptom rating; Cohen's d = -1.01). 29.8% of patients met the criteria for a metabolic syndrome diagnosis according to the International Diabetes Federation (IDF). In this group of cases, triglycerides, cholesterol and blood glucose improved markedly at discharge. DISCUSSION The presented quality control measures clearly contribute to an enhanced transparency in terms of a comprehensive quality profile. The findings from various outcome parameters indicate that patients benefit from the treatment.
