Abstract
The Patient Event Sequencing module computes the days between two user-specified events and summarizes the distribution within the cohort. It assesses the plausibility of the sequence of two user-provided clinical events as they appear in a patient’s record. This allows the user to ensure that the two events, like a cancer diagnosis and chemotherapy, occur in a sensible order and within an expected length of time.
Data Requirements
Probe
Clinical Assessment
Access Package
# install.packages("devtools")
devtools::install_github('ssdqa/patienteventsequencing')Visualization Output
This check outputs a bar graph for each site showing the proportion of patients whose time between events falls within each threshold window. The dotted line represents the median proportion for each window.
Raw Output
This check produces a raw data output containing 8 columns of data:
| Column | Data Type | Definition |
|---|---|---|
site |
character | the name of the site being targeted |
num_day |
numeric | the number of days between event A and event B, using the date of event A as the index |
user_cutoff |
numeric | the user provided threshold for days between the events |
event_a_name |
character | the name of event A |
event_b_name |
character | the name of event B |
pt_ct |
numeric | the number of patients with num_days between the two events |
total_pts |
numeric | the total number of patients in the cohort |
pts_without_both |
numeric | the number of patients that are missing one of or both of the events, which prevents a date differential from being computed |
