Purpose: Interdisciplinary tumor boards (ITBs) represent a central part of standard cancer care defining a guidelines-guided treatment plan adapted to the patient's capabilities, comorbidities and wishes in a multi-professional team. The implementation rate of ITB recommendations can be monitored by structured adherence analyses. But (inter)national definitions how to measure the level of implementation are missing. Here, we present results of 4 years of ITB adherence analyses in a bicentric German Comprehensive Cancer Center (CCC).
Methods: Between 2018 and 2021, for at least 1 month, the implementation rate of recommendations of 8 different ITBs of 2 CCC sites was evaluated manually according to harmonized criteria between both sites regarding the degree of implementation of ITB's recommendations.
Results: In total, 1104 cases were analyzed (65% male, 35% female). Mean distance from patient's home to the CCC was 57 km (range 0.8-560.6 km). For 949 cases (86%) with known follow-up, the adherence rate was 91.9% (95% CI 0.9; 0.935). In 8.1%, ITB decisions were not implemented due to medical reasons (45.4%), patient's wish (35.1%) and unknown reasons (19.5%). Logistic regression revealed neither age (OR = 0.998, p = 0.90), nor gender (OR = 0.98, p = 0.92) or the distance from patient's home to the CCC (OR = 1.001, p = 0.54) were significantly associated with ITB adherence.
Conclusion: ITB adherences analyses can serve as a quality management tool to monitor the implementation rate of ITB recommendations and to stay in contact with practitioners, other hospitals and state cancer registries to share data and resources in accordance with data protection requirements for continuously improvement of quality management and patient care.
