Health informatics applications will be a cornerstone in the next generation quality-and-efficiency health care system. Health care is delivered from many different specialties, to many different patients with complex diseases and comorbidity. A one size fits all approach is not adequate to reach the Triple Aim of improving the patient experience of care, improving the health of populations, and reducing the per capita cost of health care. Health informatics applications must be built to be adaptable and sensitive to the complex contexts they will be used in. To enhance patient-centeredness in the 21st Century healthcare, research attention should be focused on investigating and designing models contributing to effective health information retrieval process.
