Miller et al developed a risk score based on the TENOR (The Epidemiology and Natural History of Asthma: Outcomes and Treatment Regimens) study. Additional factors can be added to this to reflect patient reported outcomes and healthcare utilization. The authors are from Genentech, Novartis, University of California, National Jewish Medical and Research Center (Denver) and Harvard Medical School.
Additional measures to include with the TENOR risk score:
(1) patient reported outcomes (PRO)
(2) healthcare use variables
PRO Parameters:
(1) health compared to others
(2) night-time awakenings

subscore for PRO parameters =
= (points for health comparison) + (points for wakings at night)
subscore for healthcare use =
= (points for ED visits) + (points for scheduled visits)
Interpretation:
• minimum PRO or healthcare use subscores: 0
• maximum PRO subscore: 4
• maximum healthcare use subscore: 14
• maximum TENOR score + PRO subscore: 22
• maximum TENOR score + healthcare use subscore: 32
• maximum TENOR score + both subscores: 36
