Table 1. Impact of various policy options with regard to mid-CP follow-up on the number of cases of tuberculosis treatment failures detected early1 and laboratory workload.
| Policy Options for mid-CP follow-up | Total patients tested (%)2 | Cases of TreatmentFailure detected early1(Gain/Loss)3 | Number needed to testto detect one case oftreatment failure early1 |
| Continue as per present guideline | 10055 (100) | 323 | 31 |
| Discontinue in new end-IP negative cases | 3154 (31) | 323 | 10 |
| Discontinue in all new cases | 2040 (20) | 206 (−117) | 10 |
| Discontinue in all end-IP negative cases | 1531 (15) | 214 (−109) | 7 |
| Schedule mid-CP follow-up to 5th month for all cases | 10055 (100) | 421 (+98) | 24 |
1
Detected as a case of treatment failure around two-three months earlier than if detected at the end of the treatment.
2
Percentage calculated by taking follow-up required under present policy as denominator.
3
Gain/Loss in absolute numbers indicated respectively by a positive or a negative sign; CP-Continuation Phase of TB treatment.
