The distribution of cases at the different levels
of compliance is termed “compliance structure''.
Sputum Conversion by levels of compliance : The
proportion of cases becoming sputum negative at
the end of the prescribed period of
chemotherapy, by the various rates of
Mix of regimens : In those districts which have
implemented SCC, not all the cases are put on
SCC. The proportions put on SR and SCC would
vary from DTP to DTP, ranging between two
hypothetical extremes of 100% on SR with 0% on
SCC at one end and 0% on SR with 100% on
SCC at the other end. The situation of mix of

compliance, out of those actually put on
treatment as observed in operational studies is
computed in Tables 1 & 2 columns 4 & 5. The
computation is based on the observation that
some proportions of cases become sputum
negative in 1st, 2nd and 3rd levels of compliance
and remain so even at the end of the stipulated
period of treatment, inspite of not having
consumed the prescribed number of doses of
drugs 10,11.

from I to XI in Table 3 & Figure.
Treatment efficiency : (E,F,G in Fig.) It is the
proportion of cases estimated to be sputum
negative at the end of the treatment period out of
those put on treatment (i.e. the number
converted out of 660 cases in district of average
performance). Sputum conversions have been
calculated taking into consideration the sum-total
