For each of the following evaluated clinical states: Code Y Comorbidity exists Code N Comorbidity does not exist Comorbidities must be recorded in the following order. - Respiratory: Chronic restrictive, obstructive, or vascular respiratory disease resulting in severe exercise restriction i.e., unable to climb stairs or perform household duties; or documented chronic hypoxia, hypercapnia, secondary polycythemia, severe pulmonary hypertension (>40mmHg), or respiratory dependency.
- Cardiovascular: New York Heart Association Class IV i.e. angina or symptoms at rest or on minimal exertion e.g. getting dressed or self-care.
- Liver: Biopsy proven cirrhosis and documented portal hypertension: episodes of past upper GI bleeding attributed to portal hypertension; or prior episodes of hepatic failure/encephalopathy/coma.
- Renal: Receiving chronic dialysis.
- Immune suppressive disease: The patient has a disease that is sufficiently advanced to suppress resistance to infection. e.g., leukaemia, lymphoma, AIDS.
- Immunosuppressive therapy: The patient has received therapy that suppresses resistance to infection e.g. immunosuppression, chemotherapy, radiation, long term or recent high dose steroids.
Examples: Respiratory | Cardio-vascular | Liver | Renal | Immuno- suppressive disease | Immuno- suppressive treatment | Y/N | Y/N | Y/N | Y/N | Y/N | Y/N |
Code | Code represents | YNNNNN | Respiratory comorbidity exists. Cardiovascular, liver, renal, immune- suppressive disease and immunosuppressive therapy do not exist. | NYNYNN | Cardiovascular and renal comorbidities exist. Respiratory,liver, immune- suppressive disease and immunosuppressive therapy do not exist. |
