Data analytics, particularly through visualization, significantly influences organizational decision-making, fostering ongoing improvements in quality. Applying proper statistical techniques to health data visualization enhances healthcare quality, potentially sparking a substantial shift in organizational culture. When organizational leadership recognizes the impact of healthcare data analytics on quality improvement, it can elevate the appreciation for every initiative undertaken by healthcare professionals.

Data visualization in healthcare involves the presentation of complex healthcare data in graphical or visual formats, making it easier for healthcare professionals, researchers, and policymakers to comprehend, analyse, and derive insights. It plays a crucial role in transforming complex data into actionable insights, fostering better decision-making, and ultimately improving patient outcomes and healthcare delivery.
