Instant messaging in cancer care.

Instant messaging applications, such as WhatsApp® and Telegram®, have transformed global communication, offering unique business models and minimal user expenses. Unlike traditional SMS, these apps facilitate unlimited, multimedia-rich communication globally, driven by widespread smartphone adoption. This shift not only broadens communication horizons but also enhances privacy compared to conventional voice calls. In healthcare, instant messaging, particularly unidirectional communication, proves impactful, evidenced by trials like TEXT ME and Healthy Text. These studies highlight text messages' efficacy in cardiovascular disease prevention and cancer prevention, demonstrating improved patient outcomes and behavioral changes. Bidirectional communication through instant messaging holds promise in cancer care, facilitating patient-doctor interactions, adverse event management, and medication compliance. Studies on pharmacist-run tele-oncology services and WeChat-based doctor-patient communication showcase positive impacts on chemotherapy monitoring, patient adherence, and overall survival rates. Despite these advantages, challenges arise from the use of widely available apps like WhatsApp and WeChat, including a lack of structure, constant message influx, and potential physician burnout. Innovative solutions, exemplified by the Esperto in chat® platform, introduce structured approaches to doctor-patient communication, addressing financial considerations, scheduling, and maintaining work-life balance for healthcare professionals. In conclusion, while instant messaging revolutionizes healthcare communication, challenges necessitate innovative solutions. Striking a balance between accessibility and safeguarding healthcare professionals' well-being is crucial as the digital transformation of healthcare continues.
