Rudolf et al modified the TBscore of Wejse et al to create the TBscore II. This is useful for monitoring patients with pulmonary tuberculosis. The authors are from multiple institutions in Denmark, Sweden, the United States and Guinea-Bissau.
Patient selection: adults >= 15 years of age
Parameters from the original score removed: night sweats, positive lung auscultation, pulse, temperature and hemoptysis.
Parameters:
(1) cough
(2) dyspnea
(3) chest pain
(4) anemia (anemic conjunctivae)
(5) body mass index
(6) mid-upper arm circumference in mm

where:
• The normal mid-upper arm circumference would be affected by age and gender as well as malnutrition. Note that the same cutoff is used for men and women.
total score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximums score: 8
• The higher the score the more severe the tuberculosis.

Performance:
• The area under the ROC curves ranged from 0.66 to 0.71 for therapeutic failure and from 0.68 to 0.73 for mortality.
