Abstract

Objective: To determine the effects of telephone follow-up on the reduction of noncompliance to orally-administered Amoxycillin of outpatients. Method: Subjects were 253 outpatients in Thupput Hospital, Phang-nga Province who were diagnosed as bacterial infection and had to use oral Amoxycillin for five days. Of 253, 115 were randomized to the control group and 100 to the experimental group using computer-generated number. Both groups were counseled on medication use and the importance of completing the regimen by a pharmacist. The researcher made a phone call to the experimental group at day 3 after the start of antibiotics in order to emphasize the importance of continuous use of antibiotics. At day 6 the researcher called both control and experimental groups to determine the amount of antibiotics left. The researcher concealed the objective of the telephone follow-up from the subjects in order to reduce the bias in the measurement of noncompliance. All subjects were informed that the objectives of the follow-up was to ascertain the color changing of medication, their symptom, and their problems in drug use. Results: Seventy four percent of patients in the experimental group took antibiotics continuously and completed the regimen, while 40.0% in the control group did so. Telephone follow-up reduced the risk of noncompliance by 34% (95% confidence interval=23-42). Relative risk of noncompliance with telephone follow-up was 0.43 (95% confidence interval=0.30-0.62). Number needed to treat to reduce one noncompliance case was 3 (95% confidence interval=2.38-4.35). The percentage of antibiotic left in the experimental group was 5.67, which was lower than that in the control group (21.4%). Conclusion: Telephone follow-up was effective in reducing compliance problem.
