Big data refers to immense volumes of data that cannot be managed by standard software or internet-based systems. It outperforms standard storage, processing, and analytical power. Although several definitions exist for big data, Douglas Laney's is the most widely recognized (Laney, 2001). Big data rose in three dimensions (three Vs): volume, velocity, and variety (Dash et al., 2019). Big data's "big" signifies its volume and describes pace and variety. These three Vs mainly define big data. Others have added further Vs: veracity (uncertainty of data) and value (benefits) (Abbot & Xie, 2016; Reimer & Madigan, 2019).
The phrase "big data" has gained worldwide popularity. Almost every area of study, whether industrial or academic, generates and analyzes massive data. As stated by Kardas and colleagues (2020), it is essential that an enormous amount of data, structured or not, be handled properly and because conventional software cannot handle massive data, the healthcare sector needs innovative apps and software that can employ high-end processing power quickly and affordably. Artificial intelligence (AI) and unique fusion techniques are required (Mehta & Pandit, 2018).
Wang and Wang (2020) reiterated that health care is a multi-dimensional system intended to prevent, diagnose, and cure human health concerns or impairments. Patients, doctors, and hospitals are the main components of a healthcare system. The health professions include dentists, doctors, nurses, psychologists, physiotherapists, and others. Depending on the scenario, different care degrees are necessary (Dimitrov, 2019). Professionals serve as the initial point of contact for general care, acute care requiring specialized experts, and advanced medical investigation and treatment. At all levels, health practitioners are accountable for patient medical history, clinical data, and other personal data.
Big data has grown significantly in various nations. However, it is not generally provided from the macro perspective. This integrative review examines current evidence on the impact of big data on health care concerning patient outcomes.
