TB – tuberculosis, CTD – central TB division, BMI – body mass index, MUAC – mid upper arm circumference, HIV – human immunodeficiency virus, ART – antiretroviral treatment.

*Patients with very severe undernutrition, respiratory insufficiency or poor performance status are prioritized for comprehensive assessment. A total score of more than one – to be provided inpatient care, a total score of more than three – to be provided inpatient care in a facility with an intensive care unit. **If an indicator suggests an emergency, inpatient care should be provided, irrespective of the total score.

*Modifications to the criteria provided by CTD 2021 technical guidance: blood sugar of > 128 replaced with >200. In addition, inpatient care may be provided if the treating physician feels the need for inpatient care.
