Term: Total Respiratory Morbidity (TRM)

Glossary Definition

Last Updated: 2010-08-18

Definition:

Total Respiratory Morbidity (TRM) is a measure of the burden of all types of respiratory illnesses in the population and includes any of the following respiratory illnesses: asthma, chronic or acute bronchitis, emphysema, chronic airway obstruction. In earlier MCHP research (Fransoo, et al. (2005) and (2009), this also included chronic obstructive pulmonary disease (COPD). This combination of diagnoses is used to overcome problems resulting from different physicians (or specialists) using different diagnosis codes for the same underlying illness (e.g. asthma versus chronic bronchitis).

See the Total Respiratory Morbidity (TRM) - Measuring Prevalence concept for more information on TRM, including the ICD diagnoses codes used to define this condition.
