BackgroundOxaliplatin (OXA), a third-generation platinum derivative, has become one of the main chemotherapeutic drugs for colorectal cancer and other cancers, but reports of adverse reactions are also increasing with the extensive application of OXA. In this study, post-marketing surveillance was carried out to investigate the safety profile of OXA in a real-world setting in Chinese cancer patients to provide a reference for the rational application of OXA.MethodsAll patients with cancer who received OXA-based chemotherapy in 10 tertiary hospitals in Hubei Province, China, between May 2016 and November 2016 were enrolled. A central registration method was used to document patients’ demographics, clinical use, and any incidence of adverse reactions to OXA. All adverse drug reactions (ADRs) were collected and analyzed to assess causality, severity, treatment, and outcome.ResultsIn total, 3687 patients were enrolled in this study. Approximately 64.6% of the patients were male, and 68.8% were aged 50-70 years, with a mean age of 55.3 years. The proportions of patients diagnosed with colorectal and gastric cancers were 59.3% and 31.6%, respectively. In this study, the overall incidence of ADRs and serious ADRs was 42.7% and 1.3%, respectively. The most common ADRs were gastrointestinal disorders (25.7%), blood disorders (21.1%), and peripheral nervous system disorders (8.0%). The serious ADRs identified were hypersensitivity reactions, thrombocytopenia, abnormal hepatic function, and leukopenia/neutropenia. The median onset of gastrointestinal toxicity, myelosuppression, peripheral neurotoxicity, and abnormal hepatic function was 1 d, 5 d, 1 d, and 14 d, respectively. The majority (84.7%) of hypersensitivity reactions were mild to moderate, and the median time to onset of these reactions was within the first 20 min of OXA infusion. Almost 88.0% of patients who experienced ADRs recovered or improved with treatment.ConclusionOur data suggest that OXA-induced ADRs are very common in Chinese patients with cancer; however, more attention should be paid to hypersensitivity reactions caused by OXA. This study provides a valuable reference regarding the safe application of OXA in a real-world setting.
The consequences of medication errors are more severe for high-alert medications than general drugs. Improving pharmacists’ knowledge regarding high-alert medications is important to increase drug safety and maintain patient health. This study was aimed at understanding Chinese hospital pharmacists’ knowledge regarding high-alert medications and exploring associated factors, to provide suggestions for management of high-alert medications. A total of 380 pharmacists from four hospitals in southern, northern and central China were selected through a convenience sampling method. Through a questionnaire survey, the pharmacists’ demographic sociology characteristics and knowledge regarding high-alert medications were investigated. Chi-square tests and binary logistic regression were used to analyze the factors associated with pharmacists’ knowledge regarding high-alert medications. A total of 336 valid questionnaires were returned, with an effective recovery rate of 88.4%. Among the respondents, 79.2% had high knowledge regarding high-alert medications. The analysis results show that the main factors significantly associated with pharmacists’ knowledge levels of high-alert medication were work experience and professional title, whether high alert-medication knowledge was obtained through the network channel, whether high-alert-medication knowledge was obtained through daily work practice and whether high-alert medications were double independent checked before use. Increase the sharing of work cases and knowledge cooperation among different pharmacists and departments in high-alert medications, rationally adjust and arrange the responsibilities of pharmacists, and improve the internal circulation of hospital high-alert medications are helpful to improve pharmacists’ cognitive level of high-alert medication and improve the hospital’s ability to control the risk of high-alert medication.
Traditional Chinese medicine (TCM) injection is widely used in clinical settings, but its adverse drug reactions (ADRs) can be a serious public health concern. The objective is to study the safety of TCM injection and provide suggestions for clinical use. ADR reports collected by the Hubei Adverse Drug Reaction Monitoring Center from 2014 to 2019 were analysed. The safety of TCM injections was described by descriptive analysis and three signal mining methods, including the reporting odd ratio (ROR), proportional reporting ratio (PRR) and comprehensive standard method (MHRA). The findings indicate that the age groups of 0–10 and 41–80 years had the highest rates of reporting ADRs. A total of 96.41% of the ADRs occurred within one week, mostly on the same day that the injection was administered. Among the 60 TCM injections, Shenmai, Xiangdan, Salvia, Shengmai, Astragalus and Xuebijing injection had an above average ratio of severe ADRs (12.63%). A total of 99.24% of the cases improved after treatment. There were 9 deaths whose ADRs were mainly anaphylactic shock, dyspnoea and anaphylactoid reaction. In signal mining, the three methods produced 19 signals that were the same, and 14 of them were off-label ADRs. The frequency of TCM injections in children and elderly patients should be reduced and monitored strictly. Close observation is necessary during the first seven days after receiving the injection. The clinical use of Shenmai, Xiangdan, Salvia, Shengmai, Astragalus and Xuebijing injections should be investigated. Signal mining and more research are needed on TCM injections.
