Background: Spontaneous reporting of adverse drug reactions (ADRs) is essential for the post-marketing safety evaluation of drugs. Therefore, good monitoring of ADRs is vital for strengthening drug supervision, management, and guiding rational drug use. Chinese medical institutions are the primary source of ADR case reports, but the proportion of the reports in grade IIIA hospitals is still low due to serious under-reporting. The 3rd Affiliated Hospital of Chengdu Medical College, Chengdu Pidu District People's Hospital, also has such a problem. Objective: To improve the quantity and quality of ADR reports and enhance the level of pharmacovigilance in hospitals, the Third Affiliated Hospital of Chengdu Medical College, People's Hospital of Chengdu Pidu District experienced 10 years to gradually establish a management model to improve the medical staff's reporting rate of spontaneous reporting of ADRs. The management model is led by clinical pharmacists and combines the PDCA with Teach-back methods. The purpose of this paper is to introduce the management model and discuss its advantages and shortcomings of this model. Methods: This study was conducted at the Third Affiliated Hospital of Chengdu Medical College—Chengdu Pidu District People's Hospital. From 2016, the daily management of reporting, auditing, and data improvement of adverse drug reactions in the hospital was carried out by clinical pharmacists, who used the PDCA method combined with the Teach-back method to continuously improve the reporting program of ADRs in the hospital during 2016–2021. Then, the proportion of spontaneous reports of total, new, and serious ADRs was compared before and after the intervention. Also, we performed a time series analysis using an autoregressive moving average model to assess changes in the total number of spontaneous ADR reports before the intervention (2013–2015), the first intervention (2016–2018), and the second intervention (2019–2021). Results: After the combined PDCA and Teach-back method intervention, the median number of reported ADRs per year increased from 50 (range 37–55) in the pre-intervention period to 88 (range 83–162) in the first intervention period and to 374 in the second (range 312–566). Breakpoint regression analysis of the spontaneous reporting rate of ADRs showed that the instantaneous increase after the first intervention was not statistically significant (P = 0.526). However, the reporting rate of ADRs increased at a month-by-month growth rate during the second intervention compared to the first intervention. Its spontaneous reporting rate improved 1.034 times (P = 0.002). After the second intervention, the spontaneous reporting rate of ADRs transiently increased 6.111-fold (P < 0.001), and the month-to-month growth rate increased 1.024-fold (P < 0.001) again. Conclusion: The management model that combines the PDCA and the Teach-back method significantly improves the reporting rate of adverse drug reactions. [ABSTRACT FROM AUTHOR]

Background Data are lacking about the extent of drug-related problems in hospitalized patients with COPD in China. Objective Identify types and causes of drug-related problems and assess interventions performed by pharmacists. Setting Study was conducted in an academic teaching hospital in Shanghai, China. Method Between June 2017 and July 2018, 393 patients admitted to hospital for acute exacerbation of COPD hospitalized were enrolled. Patient demographics and clinical characteristics were collected. The drug-related problems and interventions were recorded and analyzed based on the Pharmaceutical Care Network Europe (PCNE)-DRP V 8.02 classification. Main outcome measures The number, types, causes, interventions, and outcomes of the problems were analyzed. Results A total of 640 DRPs, with 763 corresponding causes, were identified for 393 patients. "Treatment safety P2" was the most common type of problem (54.2%; 347/640), and the most common causes were "drug selection C1" (24.2%; 185/763), "dose selection C3" (21.5%; 164/763) and "treatment duration C4" (17.7%; 135/763). Antibiotics, corticosteroids, and proton pump inhibitors were the three primary medication classes associated with DRPs. Patients, hospitalized for more than eight days, taking ten or more drugs or having renal dysfunctions were more likely to have drug-related problems. Pharmacists totally proposed 1557 interventions to address the problems. Most interventions (91.0%; 1418/1557) were accepted, and 91.6% of the problems were solved. Conclusion The prevalence of drug-related problems among the studied COPD patients was high. Pharmacists can have an important role in addressing the problems and optimizing the safety and effectiveness of therapies for hospitalized COPD patients. [ABSTRACT FROM AUTHOR]

Objective To evaluate the impact of pharmacist interventions on antibiotic use in inpatients with respiratory tract infections in a tertiary hospital in China. Method Two independent respiratory wards were randomized into control and intervention group. Between July 2009 and April 2010, all inpatients diagnosed with respiratory tract infections were enrolled. Pharmacist interventions were performed on the physicians in the intervention group. The total cost of hospitalization, cost of antibiotics, length of hospital stay and the scores of 6 items of inappropriate antibiotic use (including indication, choice, dosage, dosing schedule, duration and conversion) were analyzed. Results The total costs of hospitalization in the intervention group were significant lower compared to the control group ($1442.3 ± 684.9 vs. $1729.6 ± 773.7, P < 0.001), as well as the cost of antibiotics ($832.0 ± 373.0 vs. $943.9 ± 412.0, P = 0.01), and the patients required shorter length of hospital stay (14.2 ± 6.2 vs. 15.8 ± 6.0 days, P = 0.03). The scores with respect to the 6 items of inappropriate antibiotic use were all lower in the intervention group than in the control group. Conclusions Pharmacist interventions, interacted directly with the physicians at ward level, could play an important role in optimizing antibiotic use, thus lead to the reduction in patients' length of hospital stay and health care cost.
