The document summarizes three joint working projects between the Greater Manchester Clinical Commissioning Strategic Clinical Network and Senate (GMCCSN) and pharmaceutical companies. The first project with Boehringer Ingelheim to map atrial fibrillation services was successful with a detailed agreement and shared goals. The deep vein thrombosis project with Bayer Healthcare did not proceed as a joint working due to historical suspicions. The door-to-balloon time project engaged Company A and Company B but was not truly joint working due to NHS reconfiguration and competition between companies. Overall results were varied, with success more likely when all partners agreed to pooled resources, clear plans, transparency, and shared patient-focused outcomes.
