Trends among patients with endometriosis over a 7-year period and the impact of the COVID-19 pandemic: experience from an academic high-level endometriosis centre in Germany

Abstract

Abstract Purpose Endometriosis is known to be an underestimated disease. Lately the awareness of the disease seems to have improved. Aim of this analysis is to provide an overview of the development of treatment of patients diagnosed with endometriosis. This includes a special scope on implications of the COVID-19 pandemic since in multiple settings postponed treatments resulting in negative impact on prognosis were reported. Materials and methods We analysed the development of numbers of patients treated for endometriosis in an academic centre within a 7-year period, 01/2015–12/2021, performing a systematic analysis of ICD-10-Codes from our computer system used in clinical routine. Results Treatment numbers increased over the past 7 years, i.e., 239 treated cases in 2015 vs. 679 in 2021. Following restrictions for outpatient evaluation and surgical capacity at our centre, during COVID-19 pandemic the numbers of treated patients were reduced, especially in the first lockdown period (03/22/2020–05/05/2020 vs. same period in 2019: outpatient clinic (9 vs. 36; p < 0.001), patients surgically treated (27 vs. 52; p < 0,001)). The comparison of 2020 to 2019 showed a reduction in April 2020 of − 37% in outpatient department and up to − 90% for surgically treated patients. Comparing to 2019, we found a reduction of surgical interventions in 2020 by − 9% and an increase by 83% in 2021. Conclusions Raising numbers of patients treated for endometriosis point to a new awareness for the disease. After the decline during the lockdown period numbers raised again, leading to a delay, but not an omission of treatment. A certified endometriosis centre with established and well-organized structures is required to improve not only treatment results but also quality of life of those affected.
