摘要
目的:通过对本院药品不良反应信息汇总,分析药品不良反应的发生情况,并对药品不良反应自发报告模式进行探讨。方法采用病例回顾性研究的方法,总结不良反应发生状况,包括患者的基本资料,药品及其不良反应的特点,发生率,严重度等因素。结果:本院药品不良反应的发生率为0.0077%,住院患者药品不良反应的发生率为0.0517%,门诊发生率为0.0067%,老年患者药品不良反应的发生率较高,A型药品不良反应的发生率较高,抗生素类药物不良反应的发生率较高。轻度和中度药品不良反应的发生率分别为50.0%和46.8%。27.7%的药品不良反应是可预防的。71.4%的药品不良反应至少存在一种易感因素,最常见的易感因素为多种药物合并使用和多种合并症。对患者特征与药品不良反应特征进行相关性分析发现,A型药品不良反应在老年患者的发生率较高,B型药品不良反应在中青年患者的发生率较高。结论:本院药品不良反应自发报告发生情况与其他医院相似。避免药品不良反应常见的易感因素可显著减少或预防药品不良反应的发生,从而保证临床用药安全有效。
Objective AIM To characterize the pattern of ADRs reported in a tertiary teaching hospital in China.METHODS Retrospective evaluation was done for various parameters including patient demographics,drug and reaction characteristics,outcome,causality,severity,preventability,and predisposing factors.RESULTS A total of 220 ADRs were evaluated.The overall incidence of ADR was 0.0077%.At least one ADR was reported in 0.0517%of the hospitalized patients and in 0.0067%of me oulpatients.Incidence of ADRs among elderly adults and older adults were significantly higher than other age groups.Type A reactions accounted for majority of the reports.Antibacterials were the drug class most commonly involved.Upon causality assessment,majority of the reports were rated as probable.Mild and moderate reactions accounted for 50.0%and 46.8%,respectively.In 27.7%of the reports,the reaction was considered to be preventable.At least one predisposing factor was present in 71.4%of the reports and the most common predisposing factors associated were polypharmacy and multiple disease state.Evaluating the relationship between patient characteristics and reaction characteristics,type A reactions were more common among older and elderly adults and type B reactions more common in adults compared to other age groups.CONCLUSION The pattern of ADRs reported in our hospital is comparable with the results of studies conducted in hospital set up elsewhere.Our evaluations revealed opportunities for interventions especially for the preventable ADRs to ensure safer drug use.
