The VIP1 study is endorsed by ESICM (European Society of Intensive Care Medicine)


Background and scope

This study will address the ICU care of the very old, defined as patients ≥ 80 years, admitted to the ICU. The study will be the first large multinational study, with a basis in Europe, to study the frequency of ICU admission in the very old patients, the use of common ICU resources including ICU and hospital LOS. Outcome will be registered as outcome at ICU discharge and at 30 days. We will also study the feasibility of a very simple frailty index.

Recruitment of patients

The goal is to recruit 20 consecutive ICU patients ≥ 80 years, or continue for a 3 month period (whichever comes first). We hope to recruit 100 – 500 ICUs (2,000 – 10,000 patients) in this large epidemiological study. Patient IDs will not be registered, only gender and age (in rounded years). Each participating ICU must comply with their country’s National rules for this type of study.

Data security and storage

Data security in the VIP1 study follows industry standards. The data entry forms and database are hosted on a secure server and are composed of a MySQL database and PHP web-application. Data is secured with Secure Socket Layer (SSL) encryption when sent into or retrieved from the database. Data is stored on servers located on the campus of Aarhus University, Aarhus C, Denmark. The servers are maintained and managed in a professional server environment in coorporation between the IT Department of the University and the Department of Clinical Medicine. The server rooms have physical access control and logging of personnel access. Other security measures include hardware and software firewalls. For technical inquiries please contact the datamanager:


Desease severity scores used in the study

These calculators may be of use if your own electronic health record system does not provide calculation of disease severity scores. These are suggestions.

NB. Make sure you are using the correct units. Some of the calculators allow for using either mg/dl or mmol/l. In some calculators you can switch between US units / SI units by clicking at the bottom.

Combined calculation of SAPS II, SOFA and APACHE II

NB. In the ClinCalc calculators a period (.) must be used as decimal separator or wrong results may occur.
