Aggregate data:
Data extracted from individual health records and combined to form de-identified information about groups of patients that can be compared and analyzed
Comparative data:
Data that are used for benchmarking or other comparisons within or across healthcare organizations. continuous variables are either interval or ratio level. With continuous variables there are no gaps in the measurement data. For example, an individual’s weight may be 120 or 121 or any weight between 120 and 121. Continuous variables include fractions. Arithmetic operations—addition, subtraction, multiplication, and division—may be performed on continuous variables.
Patient-centered medical home (PCMH):
A program to provide comprehensive primary care that partners the physicians with the patient and his or her family to allow better access to healthcare and improved outcomes Patient-centered care involves transforming the relationship between providers and patients from the traditional model, in which a care provider prescribes the same treatment for most patients with similar diagnoses or conditions, into a patient-provider partnership that considers treatment options based on a patient’s unique concerns, preferences, and values.
Patient-centered care also focuses on the health outcomes that are important to individual patients, addressing questions such as: “Will this treatment improve the quality of my life? Given my lifestyle and preferences, which options are best for me? How will the implications of a particular therapy affect my family?” To answer these questions, there must be more and better communication among care providers, patients, and patients’ families. It requires health care providers, hospital administrators, and
