Using metrics to measure the impact of your sales efforts on patient outcomes can also present some challenges and objections that you need to overcome. Here are some of the common ones and how to handle them. First, you might encounter data quality and availability issues, such as incomplete, inaccurate, or outdated data, or lack of access to data sources. To overcome this, you should work with the hospital to establish data-sharing agreements, protocols, and standards, and to validate and verify the data that you use. Second, you might face skepticism and resistance from some stakeholders, who might question the validity, reliability, or relevance of your metrics, or who might have competing or conflicting interests or agendas. To overcome this, you should provide transparent and objective sources and methods for your metrics, and address any concerns or questions that they might have. Third, you might deal with complexity and variability issues, such as multiple or changing factors, variables, or outcomes that affect or influence your metrics, or that make it difficult to isolate or attribute the impact of your sales efforts. To overcome this, you should use multiple and complementary metrics, and adjust and adapt them as needed, to capture and account for the complexity and variability of the situation.
