Our findings show that most countries did not distinguish between a seasonal rise in dengue cases, usually during the rainy season (see Figure 1), and the unexpected increase in cases above a defined threshold, usually called an outbreak [ 2, 12]; the number of reported cases exceeding expected levels is referred to as "aberrations" [ 13].
Their contribution in that article is to illustrate, through a practical example in one ICU, two of the simpler forms of process control charts: a 'CRAM chart' or a plot of the cumlative difference between expected and observed number of deaths, along with a 'p-chart' that uses control limits based on statistical testing at monthly intervals to look for mortality that exceeds expected levels.
