Site Specific Collection Details   


The Critical Care and Medicine Database collects medical data on patients admitted under the Medicine and Critical Care services at HSC, St. B and GGH.

Medicine and ICU collectors review patient charts (either on EPR or paper copy) and enter data into a CCMDB program on their laptops.

The Patient Record

The fundamental unit of the ICU and Medicine databases is the patient record.

A profile is created each time a patient is admitted (see Definition of a Critical Care Laptop Admission, Definition of a Medicine Laptop Admission).

Every record contains detailed information about each patient:

Diagnostic Coding

Our database program uses a locally-adapted version of ICD-10 (International Classification of Diseases) to capture the pertinent diagnostic information for each patient.

There are three elements to our coding method:

1. The diagnoses are divided into three “bins”.

2. The diagnostic codes range from very specific to more general.

The goal is to code the most specific diagnosis possible.

If a specific code does not exist, there are many “waste basket” codes that are made for virtually every body system and type of diagnosis.

For example:

  • if the patient presents with a vasculitis, but it’s specific identity is not known, use the more general “waste basket” code Vasculopathy/vasculitis, NOS.

Some other examples:

3. Diagnostic codes can be combined together.

Some diagnoses are combined together by using the same priority number.

Some reasons for such combinations are:

Intervention Coding

Our database program uses a locally-adapted version of CCI (Canadian Classification of Interventions) to capture the interventions/procedures done during the patient’s admission.

1. CCI codes are divided into four categories:

  • Therapeutic interventions: ex. amputation of ischemic limb.
  • Diagnostic interventions: ex. renal biopsy.
  • Obstetrical interventions: ex. induction of labour
  • Imaging interventions: ex. CT head

2. The CCI codes are collected by two methods:

  • The “menu-driven” method, where the body part is combined with the intervention done to it. Ex. (T) Tibia, Fibula + fixation.
  • The “picklist” method, where certain interventions can simply be selected from a list. Ex. Transfusion of PRBC.

3. The CCI codes are divided into two “bins”:

  • Admit CCI’s - procedures done within 48 hours prior to admission.
  • Acquired CCI’s - procedures done during the current admission, listed by date.
