Rapid diagnostic pathways for prostate cancer: A realist synthesis.

Introduction: The NHS Long-term Plan outlines a number of approaches to address delays and diagnose three out of four cancers at an early stage, and yet patients regularly experience delays to diagnosis. Attempts to address such delays include the implementation of a number of rapid diagnosis pathways (RDPs). This realist review explores rapid diagnosis pathways for prostate cancer, identifying approaches to RDPs, as well as generating theories regarding what works, for whom and under which circumstances.
