| dc.description.abstract | This check provides analyses to identify anomalous data across time at the level of a single site. The Patient Record Consistency module, part of the larger SSDQA ecosystem, tests the consistency of clinical data representation within a patient's record. The goal is to ensure that the patient's information is confirmatory and complete, such that two events that are expected to co-exist do both occur within the same patient (i.e. a leukemia diagnosis and chemotherapy). |

| local.description.viz | This check's visual output depends on the time increment input by the user. <br><br>For yearly time increments, this check outputs a control chart that highlights anomalies in the proportion of patients per event category. A `P Prime` chart is used to account for the high sample size, which means that the standard deviation is multiplied by a numerical constant. Blue dots along the line indicate non-anomalous values, while orange dots are anomalies.Only one event category should be specified via the `event_filter` parameter to be displayed on the graph. Any of the four options seen in the other output may be chosen with `a`, `b`, `both`, or `neither`.<br><br>For smaller time increments (by month or smaller), seasonality can make it difficult to detect true anomalies in a time series. This output computes anomalies while ignoring seasonality and outputs 2 graphs: 1. A time series line graph with anomalies highlighted with a red dot. 2. A 4-facet time series line graph that demonstrates the decomposition of the anomalies to make it more clear how the anomalies were identified. |
