Under- and over-consumption intermittent TB treatment among rural TB patients in south-west China.
OBJECTIVE
To assess adherence to intermittent directly observed treatment (DOT) during the 2-month intensive phase of tuberculosis (TB) treatment in south-west rural China.


METHODS
A cross-sectional study was conducted in Simao Prefecture, Yunnan Province, China. One hundred and thirty new TB patients registered under DOTS and treated during the 2-month intensive phase and their observers were separately interviewed at their homes using structured questionnaires. Numbers of packs of TB drugs were checked on the spot.


RESULTS
Of 130 visits, the same percentage (3.1%) of patients and their observers reported missing > or =2 consecutive weeks of treatment (prevalence-adjusted kappa = 0.94). The percentages who missed > or =20% of the packs, as reported by patients and observers, were 3.8 and 2.3, respectively (prevalence-adjusted kappa = 0.969). According to the pill count, nine patients (7%) had missed > or =20% of the packs, 10 had over-consumed TB drugs and two had lost respectively five and six packs. Eight of the 10 who had over-consumed had done so due to confusion in the days of the month, and two because they wanted a quicker recovery.


CONCLUSIONS
Intermittent regimens in China need to be more carefully monitored to avoid over-consumption of anti-tuberculosis drugs in addition to non-adherence due to under-consumption.
