A field trial to assess the effectiveness of a reminder
sticker in reducing immunization dropout rates was conducted in two
districts of Addis Ababa between October 14, 1991 and January 31,
1992. A total of 703 children were entered into the study. The
study population was divided into intervention and control groups
according to a randomly determined schedule. The intervention
group received the reminder sticker and the control group did not
recei ve the sticker. All other services were identical. A
baseline interview documented the socio-demographic and maternal
characteristics potentially related to immunization services
utilization and revealed no statistically significant differences
between the intervention and the control group. The dropout rates
were 7.3% and 13.3% in the intervention and control groups
respectively. The Relative Risk of being a dropout in the
intervention group was 0.55(0.35,0.87) . This difference is
clinically and statistically (p<.Ol) significant. Therefore, it is
concluded that the reminder sticker is effective in reducing
immunization dropout rates. Further, large scale investigations
under operational conditions are recommended prior to the routine
introduction of stickers into the immunization services |
