Care for patients with a malignant haematological disorder in Wales has been revised significantly since the mid-1990s. Recommendations from expert groups stated that a uniformly high standard of care should be provided as close to the patient’s home as possible and variations in practice that had been causing concern and distress to patients and their families be reduced. The All Wales Haematology Nurses Group was established to promote and disseminate standards and guidelines that would contribute to achieving these aims. The basis for the group’s work was transformational leadership and collaborative practice. Work is ongoing and the group is planning to consolidate achievements to date through country-wide audit and professional education.
