RESUMO
BACKGROUND: Upper respiratory infections account for many of the visits in primary care. As most URIs are caused by viruses, antibiotic therapy is not desirable. However, for URI treatment antibiotic therapy is commonly used, which causes many public health problems such as drug resistant bacteria and high medical cost. This paper examines patient knowledge of the normal presentation of a URI, beliefs in the effectiveness of antibiotics and health care utilization. METHODS: A survey of 200 outpatients or their families was conducted in one university hospital from March to April, 1998. Two URI conditions were given for the survey:(1) a condition of 5 days' duration with a cough, sore throat, and clear nasal discharge (question 1), (2) a condition of the same symptom as (1) except a discolored nasal discharge (question 2). For various questions in each of these conditions they were to answer in 5 point Likert type scale. Statistical softwares of SAS 8.0 and GAUSS 3.21 were used for analyzing the survey data. RESULTS: For question 1, 61 % of the sample reported that they would seek care from a physician while for question 2, 75 % of the sample reported that they would do so (p<.01). The health service suppliers, in the order of visiting frequencies, were pharmacy (58 %), hospital (38 %), no visit (2.5 %), public health center (0.5 %), and Chinese medicine clinic (0.5 %) for question 1 and pharmacy (54 %), hospital (42 %), no visit (2 %), Chinese medicine clinic (0.5 %) and public health center (0.0 %) for question 2. For question 1, 54 % of the sample and for question 2, 63 % reported that they believe antibiotics were effective (p=.068). For question 1, 79.5 % and for question 2, 89.5 % of the subjects reported that they had complied to prescriptions of doctors or pharmacists (p<0.05). Out of those subjects, only 19.5 % for question 1 and 21.2 % for question 2 reported that they checked the presence of antibiotics in the prescriptions. A multivariate analysis shows that older people, normally used antibiotics and current smokers had higher tendency of seeking care and stronger beliefs in the effectiveness of antibiotics. CONCLUSION: There is a lack in patient understanding of normal presentation of a URI and the effectiveness of antibiotics as a treatment. A confusion about the meaning ofa discolored nasal discharge is particularly evident. The patients visited pharmacies more often than hospitals, and majority of them (80 %) did not know the details of their prescriptions.
