Missing Data
– We need to learn and educate on what can Big Data do, and cannot; instead of either relying on wild assumptions or mindlessly collecting everything. Good education will help health personnel cooperate.
Selection Bias
– Trends toward higher quality Big Data will help mitigate this.
Data Analysis and Training
– This is the real problem here, as we might also need more research into Big Data. Even so, relying on training is not enough. Explanation of requirements in Plain English is as important. I saw ELI5 everywhere on the internet.
Privacy and Ethical Issue
– Another real problem is whether we can have “Big Data” in the first place, if we cannot ethically collect the data.
