Hintergrund Gestationsdiabetes (GDM) ist die häufigste Stoffwechselerkrankung während der Schwangerschaft und mit einem höheren Lebenszeitrisiko eines Typ-2-Diabetes mellitus assoziiert. Daher ist eine, den Bedarfen der Frauen gerechte, strukturierte GDM-Nachsorge bedeutsam. Jedoch fehlen Daten, inwiefern von GDM betroffene Frauen leitliniengerecht nachbetreut werden, welche Faktoren assoziiert sind oder wie das Zusammenspiel zwischen den behandelnden Leistungserbringenden funktioniert. Ziel des Projektes "Nachsorge bei Gestationsdiabetes" (GestDiNa_basic) ist es, mittels eines Mixed-Methods-Ansatzes die Nachsorgesituation umfangreich abzubilden und ein patientinnenzentriertes und effektives Versorgungsmodell abzuleiten.

Introduction Women with gestational diabetes mellitus (GDM) have a higher risk of developing type 2 diabetes mellitus compared with women who never had GDM. Consequently, the question of structured aftercare for GDM has emerged. In all probability, many women do not receive care according to the guidelines. In particular, the process and interaction between obstetrical, diabetic, gynaecological, paediatric and general practitioner care lacks clear definitions. Thus, our first goal is to analyse the current aftercare situation for women with GDM in Germany, for example, the participation rate in aftercare diabetes screening, as well as reasons and attitudes stated by healthcare providers to offer these services and by patients to participate (or not). Second, we want to develop an appropriate, effective and patient-centred care model. Methods and analysis This is a population-based mixed methods study using both quantitative and qualitative research approaches. In various working packages, we evaluate data of the GestDiab register, of the Association of Statutory Health Insurance Physicians of North Rhine and the participating insurance companies (AOK Rheinland/Hamburg, BARMER, DAK Gesundheit, IKK classic, pronova BKK). In addition, quantitative (postal surveys) and qualitative (interviews) surveys will be conducted with randomly selected healthcare providers (diabetologists, gynaecologists, paediatricians and midwives) and affected women, to be subsequently analysed. All results will then be jointly examined and evaluated. Ethics and dissemination The study was approved by the ethics committee of the Faculty of Medicine, Heinrich-Heine-University Düsseldorf (Ethics Committee No.: 2019-738). Participants of the postal surveys and interviews will be informed in detail about the study and the use of data as well as the underlying data protection regulations before voluntarily participating. The study results will be disseminated through peer-reviewed journals, conferences and public information. Trial registration number DRKS00020283.

Einleitung Gestationsdiabetes (GDM) ist eine Komplikation während der Schwangerschaft. Je nach Datenbasis und Definition schwankt die Prävalenz zwischen 4 % und 20 %. Epidemiologische Studien zeigen, dass für betroffene Mütter höhere Risiken für die spätere Entwicklung eines Typ-2-Diabetes bestehen.

Introduction Gestational diabetes (GDM), a complication during pregnancy, has a prevalence between 4% and 20% depending on the database and definition. Epidemiological studies show that affected women have an elevated risk of type 2 diabetes later in life. Therefore, structured postnatal care is crucial.
