Does routine home visiting improve the return rate and outcome of DOTS patients who delay treatment?

ABSTRACT

Over a period of 6 months the effect of home visits on compliance with directly observed therapy, short course [DOTS], was studied on 480 new smear-positive tuberculosis patients who had delayed collecting their drugs on one occasion. Patients registered at 15 tuberculosis treatment centers in Baghdad, Iraq, were randomized to an intervention group [receiving home visits from trained personnel] or a control group. Home visits were highly effective in improving the return to treatment of patients who were late for treatment [231/240, 96.3%]. The intervention group showed a higher treatment success rate [94.2% versus 76.7%], lower default rate [0.8% versus 10.0%] and higher smear conversion rate after the end of treatment [92.9% versus 75.0%] than controls. Home visiting by trained personnel significantly improves patient compliance with DOTS
