In most third world countries, self-medication is common and pharmacies, drug stores and drug shops are important providers of health advice and inexpensive medicines. We used exit interviews to assess drug sellers'/dispensers' roles and consumers' behaviour in Kibaha district, Coast region, Tanzania. Exit interviews with mothers/guardians reported the following childhood conditions treated with or without prescriptions at drug shops: respiratory infections (34%), fever (21%), a combination of diarrhoea, acute respiratory infection (ARI) and fever (14%), diarrhoea alone (13%) and other conditions (17%). The majority of drug sellers/dispensers prescribed or dispensed branded drugs (85%) for most mothers/guardians who visited these drug shops. In addition, antibiotics in total were prescribed for 31% of the mothers/guardians. Of the antibiotics dispensed, 38% were not prescribed by clinicians. In total, oral rehydration salts (ORSs) (3%), antimalarials (sulphadoxine/pyrimethamine) (24%) and antipyretics (11%), were prescribed in 20% but were bought by only 9%; multivitamins (6%), cough mixtures (4%) and other drugs (2%) (antihelminthics, benzylbenzoate emulsions, ear and eye drops) were also purchased from these facilities. Of the diarrhoea case histories presented by simulated clients at the drug shops, only 35% of the bloody diarrhoea scenarios were accurately diagnosed for getting antibiotics as compared with 44% for watery diarrhoea for which the use of antibiotics were wrongly advised (P<0.01). Furthermore, drug sellers/dispensers in these drug shops recommended use of ORS less frequently (3%) for a combination of diarrhoea, ARI and fever, and 2% for ARI alone than for watery (29%) and bloody diarrhoea (32%), respectively, for children under five years of age (P<0.001). Antimicrobial agents were advised for ARI (38%), watery diarrhoea (44%) and bloody diarrhoea (35%), respectively, with no significant difference among the three common childhood conditions. Antipyretics were advised in almost all childhood conditions but were least in watery (2%) and bloody diarrhoea (4%). This study demonstrates that antibiotics are overused in both the urban and rural settings of Kibaha district and that this is due to both clinicians'and drug sellers'prescribing practices in public and private facilities. The use of branded drugs was more common than that of generic drugs in private pharmacies, drug stores and ordinary shops. It is hereby proposed that any intervention should focus on training both facilities in the district on selectively prescribing and rational use of antibiotics for ARI and diarrhoea, and also to prescribe and dispense generic drugs so that it costs patients less when they buy drugs in shops. There is a need to increase awareness in recommending the use of ORS for clients to manage watery and bloody diarrhoea, and ARI in children under five years of age.
在大多数第三世界国家,自我药疗很普遍,药店、药房和杂货店是健康建议和廉价药品的重要提供者。我们通过出院访谈评估了坦桑尼亚海岸地区基巴哈区药品销售商/药剂师的作用以及消费者的行为。对母亲/监护人的出院访谈报告了在药店接受或未接受处方治疗的以下儿童疾病:呼吸道感染(34%)、发烧(21%)、腹泻、急性呼吸道感染(ARI)和发烧的组合(14%)、单纯腹泻(13%)以及其他疾病(17%)。大多数访问这些药店的母亲/监护人中,大多数药品销售商/药剂师为其开具或配发了品牌药(85%)。此外,总共31%的母亲/监护人被开具了抗生素。在配发的抗生素中,38%并非临床医生所开。总体而言,口服补液盐(ORSs)(3%)、抗疟药(磺胺多辛/乙胺嘧啶)(24%)和解热药(11%),被开具的比例为20%,但购买的比例仅为9%;多种维生素(6%)、止咳合剂(4%)和其他药物(2%)(抗蠕虫药、苯甲酸苄酯乳剂、眼药水和耳药水)也从这些机构购买。在药店模拟客户提供的腹泻病史中,只有35%的血性腹泻病例被准确诊断以获取抗生素,而水样腹泻的这一比例为44%,但对于水样腹泻却错误地建议使用抗生素(P<0.01)。此外,这些药店的药品销售商/药剂师针对腹泻、ARI和发烧组合推荐使用ORS的频率较低(3%),单独针对ARI推荐使用的频率为2%,而针对五岁以下儿童的水样腹泻(29%)和血性腹泻(32%)推荐使用的频率则分别较高(P<0.001)。针对ARI(38%)、水样腹泻(44%)和血性腹泻(35%)分别建议使用抗菌药物,这三种常见儿童疾病之间无显著差异。几乎在所有儿童疾病中都建议使用退热药,但在水样腹泻(2%)和血性腹泻(4%)中使用最少。这项研究表明,基巴哈区的城市和农村地区抗生素均被过度使用,这是由于公共和私人机构中临床医生和药品销售商的处方行为所致。在私人药店、药房和普通商店中,品牌药的使用比非专利药更为普遍。特此建议,任何干预措施都应侧重于培训该地区的两类机构,使其针对ARI和腹泻选择性地开具和合理使用抗生素,并开具和配发非专利药,以便患者在商店购买药品时花费更少。有必要提高意识,建议客户使用ORS来处理五岁以下儿童的水样和血性腹泻以及ARI。
