Patients with chronic conditions are often scheduled for routine follow-up appointments at fixed intervals, even when these visits are not always medically necessary. Research shows that over 18% of such consultations can be avoided (Klaas et al., 2024). The WACHT-NIET project therefore focuses on a new, data-driven approach to scheduling, where follow-up appointments are based on medical necessity as well as patient preferences.

In collaboration with general practitioners, patients, and healthcare partners, WACHT-NIET develops an integrated invitation and scheduling system for patients with chronic kidney disease (CKD). Based on laboratory results and patient questionnaires, the system determines whether a follow-up consultation is needed or desired by the patient. Appointments are then only scheduled when necessary, with the goal of ensuring timely access to care (target: 98% of patients seen within one week).

The project combines data analysis, predictive modeling, and optimization algorithms to improve both clinical decision-making and operational planning. It also addresses the appropriate distribution of care between primary and secondary care, and explores risk-based follow-up instead of fixed scheduling intervals. The approach is being tested in practice at the Isala hospital and participating general practices. Key outcomes include access times, number of consultations, workforce efficiency, and patient satisfaction.

WACHT-NIET contributes to more sustainable healthcare by reducing unnecessary appointments, improving the use of available capacity, and ensuring that patients receive the right care at the right time.
