View source for Conversion of old registry fields to new dispo fields

This article documents how the new [[:Category:2016 Time and Place changes]] fields are populated from old data. 

== Steps ==
Run Sub Dispo_populate() in the Ttenbergen 19:02, 2016 July 8 (CDT) version of [[CFE]]. Can re-run whole thing if fixes are required. 

== Scope ==
The old fields are no longer being filled out as of dispo > 2016-07-01.
The new fields have been filled in for some time before that, but checks were added over time, so earlier entries have quite unreliable data in them. 

New fields were cross-checked and populated from old data where appropriate. Discussed and finalized w Julie some time ago Ttenbergen 15:31, 2016 November 21 (CST)

== location fields ==
===Pre acute living situation field===
This will not be a direct translation with identical meaning. 
: If [[Overstay]] Project, 
:: "From Apartment" -> "Apartment"
:: "From Assisted Living" -> "Assisted Living"
:: "From Personal Care Home" -> "Personal Care Home"
:: "From Supportive Housing" -> "Supportive Housing"
:: "From House" -> "House"
:: -> "Chronic Health Facility"
:: -> "Prison / Jail / Correctional Institution"
:: -> "[[Homeless]]"
:: "From other" -> "other - known but not listed"
:: "From  location missing" -> "location missing/unknown"
:: else (for CC or Med before overstay project) -> new value '''"legacy empty"''' that would not be available to collectors

===Pre-admit Inpatient Institution field===
This will not be a direct translation with identical meaning. 
: if [[Hospital previous]] + type of unit from [[admit from]] correspond to inpt location
:: then -> [[Hospital previous]] + type of unit from [[admit from]]
:: else -> new value '''"legacy empty"''' that would not be available to collectors

===[[Previous Service field]]===
This will not be a direct translation with identical meaning. 
: If [[Service Sending to ICU]]
:: "Cardiac surgery" -> "Cardiac surgery
:: "Cardiology" -> "Cardiology
:: "Family Medicine" -> "Family Medicine
:: "General surgery" -> "General surgery"
:: "Medicine" -> "Medicine"
:: "Nephrology" -> "Nephrology"
:: "Neurosurgery" -> "Neurosurgery"
:: "Ob/Gyne" -> "Ob/Gyne"
:: "Ortho surgery" -> "Ortho surgery"
:: "Plastic surgery" -> "Plastic surgery"
:: "Psych" -> "Psych"
:: "Thoracic surgery" -> "Thoracic surgery"
:: "Urologic surgery" -> "Urology surgery"
:: "Vascular surgery" -> "Vascular surgery"
:: "z_not an inpatient" -> "not applicable" 
:: "z_not applicable" -> "not applicable"
:: "z_other" -> "other (known but not on list)"
:: "z_other not on list" -> "other (known but not on list)"
:: "z_unknown" -> "unknown"
:: else -> new value '''"legacy empty"''' that would not be available to collectors

No equivalents exist in old data for new "Emergency Medicine", "Neurology" and "Oncology" so these would be captured under "other" if they ever happened.

===Previous Location field===
: -> combination of [[Hospital previous]], [[Admit from]] and [[Var 1 - Admit-from Ward]]

I will generate a table ''translations_previous_location'' for this and discuss only unclear cases here.

===Service/Location===
: -> [[Location field]]

===Off ward field===
: if one of
:::: [[ICU Var 3 - Overflow]] > "" 
:::: [[ICU Var 4 - Parked in ER]] = "P"
:::: [[ICU Var 5 - Overflow]] > ""
:::: [[Med Var 5]] > ""
:: then -> true
:: else -> false

===Dispo field===
: if [[Survive / Expired]] = Expire 
:: then if exists [[Organ Donor]] 
::: then -> "died - organ donor"
::: else -> "died - NOT organ donor"
:: else 
::: if [[ICU Var 6 - AMA]] then -> "AMA"
::: else '''''combination of [[discharge to]] and [[Var 2 - Discharge-to Ward]]'''''

I will generate a table ''translations_dispo'' for this and discuss only unclear cases here. 

== Time Fields ==
===Visit Admit DtTm field===
(needs to be reconciled with [[Encounter processing]] which will likely need updating)
===Accept DtTm field===
: -> [[admit date and time]]

===Arrive DtTm field===
: -> [[admit date and time]]
: If exists [[ER Wait]] dttm
:: then overwrite with -> [[ER Wait]] dttm

===Transfer Ready DtTm field===
* old [[Transfer Ready date and time]]

===TR info status field===
: if [["No Transfer Date" in Medicine]]
:: -> "not available"
Else don't back-populate.

===Dispo DtTm field===
* old [[discharge date and time]]
