Study Overview
Brief Summary
Variation in organ donation after brain death (DBD) per million population varies markedly between countries, within country regions, between and within intensive care units (ICU). These circumstances also apply to end-of-life decisions in the ICU.
The investigators studied all ICU deaths in Sweden between 2014-2017 in ICUs that, as routine, registered treatment plan (no treatment limitation and/or treatment limitation) and DBD.
The investigators hypothesized that ICUs with high proportion of treatment limitation (withholding or withdrawing life sustaining treatment) also had less proportion of DBD.
Detailed Description
The Swedish Intensive Care Registry (SIR) collects a comprehensive data set of patient characteristics, intensive care procedures, severity of illness scores, workload and outcomes using detailed guidelines.
Continuous data are collected as raw data, validated locally and transferred electronically to the registry for central validation (confirmed to be within prespecified limits and inconsistencies and illogical entries identified). If necessary, data are returned for correction and revalidation before being accepted and added to the master database. No data are changed by SIR. At SIR's homepage there are numerous open reports, updated as soon as new incoming data are processed by SIR.
SIR has an annual 2-day course for all ICU's in registration techniques and problems and daily telephone support possibilities concerning registration questions, problems and guidance. SIR has, however not yet a systematic on-site auditing program.
Missing data regarding treatment strategy are registered and are accounted for in the study. There are no missing data regarding organ donation.
The investigators calculate the proportion of treatment limitations per ICU as the number of deaths with any treatment limitation divided by all deaths in the same ICU.

Inclusion Criteria
- •All ICU deaths in Sweden between 1/1 2014 and 31/12 2017 from
- •general and neurological intensive care units,
- •which recorded treatment strategy according to national guidelines and
- •send data according to SIR's protocol for the follow-up of all deceased intensive care patients (DBD).
Exclusion Criteria
- •Special units like paediatric (N=4), burn (N=2) and thoracic (N=8) intensive care units, due to low coverage ratio of documented treatment plan decisions in combination with a low ICU mortality rate.
- •General (N=3) ICUs that do not register documented treatment plan.
Outcomes
Primary Outcomes
Rate of organ donations after brain death (DBD)
Time Frame: The estimated period of time to the ICU death is assessed up to 5 months after patient admission time to the ICU, with a median of 1.6 days. The event is determined by clinical examination or, in some cases cerebral angiography.
Documented decision to carry out organ donation
Secondary Outcomes
- Rate of documented treatment limitations during ICU stay(The estimated period of time to the ICU documentation of treatment plan is assessed up to 5 months after patient admission time to the ICU, with a median of 14 hours. The event is determined by the note in patients medical record.)
- Incidence and type of a documented treatment limitation during ICU stay(The estimated period of time to the ICU documentation of WH and/or WD medical treatment is assessed up to 5 months after patient admission time to the ICU, with a median of 14 hours. The event is determined by the note in patients medical record.)
