I want to find patients with a diagnosis of circulatory, digestive, or injury and poisoning system issues, but not pregnancy-related events, within the same encounter or instance number and within a specific time range. The query will look for the earliest diagnosis of each condition and only include patients who have all three diagnoses in a specific order, with the circulatory system diagnosis coming first, followed by the digestive system, and then injury and poisoning. The time between each diagnosis should be less than the time between the previous diagnosis and the next one.
