Jess's rule is a principle for general practitioners to recommend reassessing their approach if a patient has completed three visits without a diagnosis or if their symptoms are worsening. Continuity of care, i.e. repeated consultations with the same doctor, is important for all patients regardless of whether they have complex medical conditions. Regular contact with one doctor allows better follow-up to previous treatment plans and increases responsibility in treatment decisions. Continuity of care reduces the risk of insufficient coordination between different health care providers. This approach can have a positive impact on the timeliness of diagnosis and treatment, including cancer.
