Note:
period.2019 = encounters for year 2019, etc., deficit: based on pre-COVID full year (2019) encounters, Colorectal Ca screening was by FIT occult fecal blood method, Cervical Ca Screening using specific dx codes under-counts (subsumed in GYN exam), but trend holds.

---

For Colorectal cancer screening, nearly all the patients do the FIT (self-administered card smear test) which bypasses regular office visit. This explains the lower deficit when compared to services that require in-person visit and interaction with the physician.

Use the slide bars to dynamically “zoom in” periods of interest, down to specific calendar dates.

Note the abrupt sustained drop at March-ending / April 2020 lasting several weeks – the “universal” effect of COVID-19

GYN Rolling mean deficit

GYN screening Deficits - Rolling mean

---

The roll(ing) mean is similar to moving averages. You may change the units of the roll by typing into the box in the lower left hand corner and clicking on . For example, weekly moving average takes 7 (for 7 day / week). For pure trending, use higher units which smoothen out the curve. If the input is zero (0), the resulting graph represents unaveraged daily counts.

Deficit Breast CA screening – Rolling mean

---

The rolling mean (same as moving average) brings to focus the deficit highlighted by the shading. To explore different averaging or roll units, change the number in the left lower corner of the graph and click on . Higher numbers will smoothen out the curve. Zero (0) yields un-averaged (original) daily visit counts.
