I want to find patients with a diagnosis of mixed hyperlipidemia or other unspecified hyperlipidemia, within any time frame, with a specificity scale of 0, and a panel accuracy scale of 100, using the i2b2 query builder. The query includes two items: Mixed hyperlipidemia and Other and unspecified hyperlipidemia, both of which are categorized under Metabolic and immunity disorders and Disorders of lipoid metabolism. The query is not inverted, and there is a total of one occurrence for each item.
