Background The prescription is one of the factors that influences rational use of medicines. The evaluation of prescribing indicators should contribute to organization of primary health care services. Objective The aim of this study was to evaluate prescribing indicators and associated factors in primary health care in the northeast health district, Belo Horizonte, Brazil. Setting Twenty primary health care units in the Northeast Health District, Belo Horizonte, Brazil. Method The study was cross sectional. Indicators proposed by World Health Organization were used to evaluate rational use of medicines. Main outcome measure Indicators evaluated were average number of medicines per prescription, proportion of medicines with antibiotic, injectable, medicines prescribed by generic name and medicines present in the essential medicines list. Results Three hundred and ninety-nine patients were interviewed. The average number of medicines per prescription was 3.5 (SD 2.2). The proportion of medicines with antibiotic, injectable, medicines prescribed by generic name and medicines present in the essential medicines list was 17.8, 9.8, 94.9, 91.4%, respectively. Patient age ≥60 years was positively associated with number of medicines per prescription (P = 0.00). Conclusion In the northeast health district of Belo Horizonte, the proportion of prescriptions of antibiotics and injections, the adoption of prescribing by generic name and the prescribing of essential medicines were satisfactory in this study considering reference values for these indicators and international scientific literature. However, the mean number of prescribed medicines requires a more in-depth evaluation.
处方是影响合理用药的因素之一。对处方指标的评估应有助于初级卫生保健服务的组织。
本研究旨在评估巴西贝洛奥里藏特东北部卫生区初级卫生保健中的处方指标及相关因素。
巴西贝洛奥里藏特东北部卫生区的20个初级卫生保健单位。
本研究为横断面研究。采用世界卫生组织提出的指标来评估合理用药情况。
评估的指标包括每张处方的平均用药数量、含抗生素药物的比例、注射剂、通用名开具的药物以及基本药物清单中的药物。
对399名患者进行了访谈。每张处方的平均用药数量为3.5（标准差2.2）。含抗生素药物、注射剂、通用名开具的药物以及基本药物清单中的药物的比例分别为17.8%、9.8%、94.9%、91.4%。患者年龄≥60岁与每张处方的用药数量呈正相关（P = 0.00）。
在贝洛奥里藏特东北部卫生区，考虑到这些指标的参考值和国际科学文献，本研究中抗生素和注射剂处方的比例、采用通用名开具处方以及基本药物的处方情况令人满意。然而，处方药物的平均数量需要更深入的评估。
