View source for Data definition for factor candidates for the Overstay2 project

This page documents the data definitions used in the [[Overstay2 scoring models]], as defined during [[re-analysis and generation of Overstay2 model]] and implemented in [[Overstay2 module]]. See [[Overstay2 Overview]] for additional context. 

== Definitions ==
=== Hospitalization ===
A hospitalization is defined as records with same ([[PHIN]] and [[Visit Admit DtTm]]).

=== Discharge Ready DtTm ===
* The first [[Transfer Ready DtTm tmp entry]] associated to a Medicine record from this [[#Hospitalization]]

=== Overstay ===
* [[#Discharge Ready DtTm]] - (Final [[Dispo DtTm]] of the [[#Hospitalization]], no matter if a medicine or critical care record)
** If there is no [[#Discharge Ready DtTm]] this will be  considered as ''no Overstay'' ie it will lead to a Overstay of 0

=== Coefficients / factors ===
Not all of these factors are used, see model (list in [[Overstay2 scoring models]]) for actual use. Also see [[Re-analysis and generation of Overstay2 model]] for how they were selected.

==== [[Age]] ====
age in years at first medicine unit admission of this [[#Hospitalization]]

=== Location / living arrangement ===
[[Re-analysis and generation of Overstay2 model#Location Grouping considerations]] explains considerations we had in generating these groupings. 

==== Homeless ====
[[Pre acute living situation field]] = "Homeless"
(present/yes=1, absent/no =0)

==== PCH/Chronic Care ====
[[Pre acute living situation field]] in ("Personal Care Home", "Chronic Health Facility")
(present/yes=1, absent/no =0)

==== FromNonWPGfacility ====
[[Previous Location]] or [[Pre-admit Inpatient Institution]] corresponding to [[s_dispo.geog]] in ('out-of-WPG','out-of-MB','out-of-CAN')
(present/yes=1, absent/no =0)

====[[Postal Code field]] based ====
===== Winnipeg_Plus =====
* (present/yes=1, absent/no =0)
* Intent is to capture people geographically located or living in Winnipeg
* construct based on [[Postal Code field#Grouping by Geographical Area]], include: 
** [[Postal Code field#MB-Winnipeg]]
** [[Postal Code field#N/A-Homeless]] - because most are located in Winnipeg and not including them would miss a significant number of people in Winnipeg
** [[Postal Code field#N/A-JDoe]] - small number but most in Winnipeg

===== MB =====
[[Province]] = 'MB' or maybe [[Postal Code]]
(present/yes=1, absent/no =0)

=====North-Western Ontario=====
construct based on [[Postal Code field#ON-NorthWestern]]
(present/yes=1, absent/no =0)

=====Northern MB=====
construct based on [[Postal Code field#MB-Northern]]
(present/yes=1, absent/no =0)

===== Rest MB =====
construct based on [[Postal Code field#MB-Rest]]
(present/yes=1, absent/no =0)

===== Rest =====
construct based on [[Postal Code field#Grouping by Geographical Area]]
* [[Postal Code field#Non-MB-Rest]]
* [[Postal Code field#N/A-notCanada]]
(present/yes=1, absent/no =0)

=== Procedures ===
==== ImplantDevice ====
has [[Admit Procedure]] combination of one of the following that might cause PCHs to deny admission: 
* '''PEG tube''' combine [[Implantation of Internal Device]] with '''[[(T) Stomach, Pylorus]]'''  (1.NF.53)
* '''Jejunostomy tube''' combine [[Implantation of Internal Device]] with [[(T) Small Intestine]]  (1.NK.53)
* '''Suprapubic catheter''' combine [[Implantation of Internal Device]] with [[(T) Ureter, Bladder or Urethra]] (1.PM.53)

=== Diagnoses  ===
[[ICD10 Diagnoses]] ([[Admit Diagnosis]] or [[Comorbid Diagnosis]]) that might prevent/delay meeting PCH/Home Care criteria.

=== post [[Overstay2 scoring model for Grace Hospital]] candidates ===
We realized after finalizing the [[Overstay2 scoring model for Grace Hospital]] that some candidate codes would be better if their definition was tweaked. 

{{DT|
Integrate these better
* re pre admit for outside Winnipeg facility discussion, change from getting from [[Previous Location]] only to getting it from both [[Previous Location]] and [[Pre-admit Inpatient Institution]]; this was missed before because we based the initial fields on the last overstay project, and back then these two fields were still combined
* re-institute amputation; before we were only looking at the CCI code, but we should consider [[Past history, loss of limb(s)]] as well }}

== Implementation ==
* [[Template:OSDD]] should be used to refer to these to consistently link here
* [[SAS]]: See {{S:\MED\MED_CCMED|Julie\MedProjects\Overstay_Project_2025\Data\6Feb2025_Oct2020toDec2024Data\prepdata_7Feb2025.sas}} contains the code that defines these for the model.
* [[CFE]]: [[Overstay2 module]] Function Get_Overstay_Parameters_from_ID
