Multidisciplinary strategies for cardiotoxicity management in ambulatory care: exploring practices, insights, and prospects for advancement

Abstract Background The management of cardiotoxicity, a significant concern in chemotherapy patients, necessitates a multidisciplinary approach. This study investigates the variability in cardiotoxicity management in outpatient settings across different medical specialties, which may lead to inconsistencies in patient care. Methods An extensive questionnaire-based study was conducted to assess the current practices and viewpoints of cardiologists, oncologists, and gynecologists in the management of cardiotoxicity among patients receiving outpatient chemotherapy in Germany. The survey engaged 1,329 medical professionals through an online platform, with a participation rate of 9.9%, amounting to 132 respondents. Results Respondents reported managing a combined total of 1,905 chemotherapy patients monthly, with individual patient loads ranging from 1 to 200. Notably, only a fraction of these patients – 37% under oncologist care and 48% under gynecologist care – underwent routine cardiological examinations. As shown in Figure 1, the three most common causes of cardiological presentations in patients undergoing chemotherapy were due to acute patient complaints (65.2%), before the start of chemotherapy (91.3%), and after the end of chemotherapy (78.3%). Furthermore, 37% of healthcare providers reported incorporating chemotherapy-induced cardiovascular toxicity risk assessments in their clinical routines. Medical history, ECG, and echocardiography were the most frequent examinations. Notably, 91.3% did not include cardiac biomarker measurements in their follow-up procedures (Figure 2). More than half of the participants (56%) expressed a need for simplified cardio-oncology guidelines. The majority of participants (84% and 83%, respectively) requested tools to assist in cardiovascular toxicity risk assessment and the implementation of appropriate therapeutic measures for patients undergoing chemotherapy. Conclusions The study draws attention to significant interdisciplinary care gaps in managing cardiotoxicity, which may contribute to an increased risk of undiagnosed cardiovascular complications in chemotherapy patients. The evident variability in cardiotoxicity management practices among different medical specialties underscores the critical need for heightened awareness and enhanced collaborative efforts. The implementation of comprehensive interdisciplinary clinical pathways and the establishment of a dedicated cardio-oncology network could potentially address these challenges, particularly in supporting primary care physicians.Figure 1Figure 2
