Each type serves a unique role in improving patient outcomes, supporting personalized medicine, and optimizing hospital data analytics.

1. Descriptive Analytics

Focuses on summarizing historical data to understand what has happened in the past. In healthcare, descriptive analytics is used to track hospital admission rates, treatment outcomes, and overall patient demographics. Healthcare data visualization tools make these insights accessible to clinicians and administrators.

2. Diagnostic Analytics

One of its purposes it has is to discover the reasons that lie behind the results and patterns. In the same fashion, healthcare data analysis can be utilized to recognize the causes of a particular treatment that has had less effectiveness in a certain group of patients. This makes doctors the facilitators of a cause investigation process and allows them to alter the care plan as needed.

3. Predictive Analytics

Employs predictive models and artificial intelligence to estimate the future results. Predictive analytics find the most significant application in customized healthcare, where it can spot the patients who are likely to develop chronic ailments or be readmitted, thus making prevention possible.

4. Prescriptive Analytics

Goes further than predictions to suggest certain actions. Prescriptive models in hospital data analytics may be able to recommend not only the best utilization of staff but also the design of treatment paths unique to each patient and even advise on the distribution of hospital resources with a view to saving time and providing care of higher quality.

5. Clinical and Omics Data Analytics

Healthcare has traditionally been divided into four categories. However, the use of deep analytics on genomics and proteomics data is having a major impact on these sectors. Besides, hospitals deeply analyze genomic and proteomic data to support personalized medicine. These technologies improve treatment specificity and efficacy by adjusting the therapy to the patient's genetic and molecular profiles.
