Informative Missingness
A statistical concept describing a condition in which the occurrence of missing values or the timing of observations is correlated with the values of the variables being measured. This phenomenon is particularly relevant in clinical data analysis, where the decision to collect a measurement often depends on a patient's underlying health status.

Informative missingness refers to a correlation between whether and when an observation occurs and the value of the observed variable itself; in settings such as the ICU, dense observations are themselves a signal of poor health status.
