2 | ins_index | integer | Instance index. A numerical index which together with the eid uniquely identifies the corresponding record in the main HESIN table. |
3 | arr_index | integer | Array index. A numerical index which together with the eid and ins_index uniquely identifies this record, i.e. eid, ins_index and arr_index together form a primary key for this table. |

12 | ccdisstat | integer, coding 7009 | Critical care discharge status. The patient status at time of discharge, for example whether they were fully ready for discharge, whether their discharge was early or delayed, whether they self-discharged, or whether they died rather than being discharged (and their organ-donor status if so). |
13 | ccdisdest | integer, coding 7010 | Critical care discharge destination. Whether the patient was discharged to the same or a different NHS hospital, an independent hospital provider, a non-hospital UK destination or to a non-UK source, or whether the patient died in the unit. |
14 | ccdisloc | integer, coding 7011 | Critical care discharge location. The principal location that the patient was discharged to for further care at the end of the critical care period. |
15 | ccapcrel | integer, coding 7012 | Critical care APC relationship id. A comparison of the dates of the critical care period and those of the associated admitted patient care episode. |
16 | bressupdays | integer, coding 7006 | Basic respiratory support days. Number of days of basic respiratory support. For the definition of basic respiratory support see Resource 141140 or the NHS CC Data Dictionary. |
17 | aressupdays | integer, coding 7006 | Advanced respiratory support days. Number of days of advanced respiratory support. For the definition of advanced respiratory support see Resource 141140 or the NHS CC Data Dictionary. |
18 | bcardsupdays | integer, coding 7006 | Basic cardiovascular support days. Number of days of basic cardiovascular support. For the definition of basic cardiovascular support see Resource 141140 or the NHS CC Data Dictionary. |
19 | acardsupdays | integer, coding 7006 | Advanced cardiovascular support days. Number of days of advanced cardiovascular support. For the definition of advanced cardiovascular support see Resource 141140 or the NHS CC Data Dictionary. |
20 | rensupdays | integer, coding 7006 | Renal support days. Number of days of renal support in the context of critical illness. For the definition of renal support see Resource 141140 or the NHS CC Data Dictionary. |
21 | neurosupdays | integer, coding 7006 | Neurological support days. Number of days of neurological support. For the definition of neurological support see Resource 141140 or the NHS CC Data Dictionary. |
22 | gisupdays | integer, coding 7006 | Gastrointestinal support days. Number of days of gastrointestinal support. For the definition of gastrointestinal support see Resource 141140 or the NHS CC Data Dictionary. |
23 | dermsupdays | integer, coding 7006 | Dermatological support days. Number of days of dermatological support. For the definition of dermatological support see Resource 141140 or the NHS CC Data Dictionary. |
24 | liversupdays | integer, coding 7006 | Liver support days. Number of days of liver support. For the definition of liver support see Resource 141140 or the NHS CC Data Dictionary. |
25 | orgsupmax | integer | Organ support maximum. Maximum number of organ systems supported at any one time, at any point in the critical care period (note that both basic and advanced categories cannot be counted at the same time). This may not be the same as the total number of organs supported throughout the critical care admission. The minimum for this variable is 0 and the maximum is 7. |
