BackgroundAdverse drug reactions (ADRs) are a leading cause of morbidity in developed countries and represent a substantial burden on health-care resources. Many countries spent 15% to 20% of their hospital budgets to treat drug complications. However, few studies have measured the pharmacoeconomic effects of ADRs on hospitalized patients in China. The study estimates the costs of ADRs as identified from the spontaneous voluntary reports completed from healthcare professionals. To do so, we calculate these costs, determine the sum of Medicare payments and their proportion of total healthcare spending, and evaluate the incidence of ADRs, characteristics of hospitalized ADR patients, and outcomes of ADRs in China.MethodsThis retrospective survey studied patients who experienced ADRs during their hospitalization at a Chinese tertiary-care teaching hospital. The patients were divided into group A and group B according to general ADRs and serious ADRs in Provisions for Adverse Drug Reaction Monitoring and Reporting. The direct costs included treatment fees, inspection fees, laboratory fees, materials fees, bed charges, drug charges, nursing care, meals, and other expenses and the sunk-cost losses were calculated according to the hospital information system (HIS). Indirect costs of ADR treatment were calculated according to the human capital approach. The epidemiological characteristics of ADRs were evaluated.Results2739 were diagnosed with ADR during the study period, which translates to an ADR rate of 0.81%. The total socioeconomic loss from 2739 cases of ADR was estimated at ¥817401.69, consisting of direct costs of ¥603252.81 and indirect costs of ¥214148.88. On average, the costs per patient amounted to ¥196.10 in group A, ¥7032.29 in group B. The sum of medicare payment and proportion were ¥219061.13 (65.23%) and ¥105422.02 (39.42%) in group A and B. The ADR incidence in old-age patients was significantly higher than in other age groups (P < 0.0001). The most common drug class associated with ADRs represented antibiotics (957 patients, 34.94%).ConclusionsThe costs of especially severe ADRs could not be ignored, and in this hospital 0.13% of patients were diagnosed with ADRs associated with relatively higher direct costs than who suffered from mild ADRs, largely due to extended hospitalization.
Osteoporosis is a most frequent systemic skeletal disease characterized as low bone mineral density and microarchitectural deterioration of bone tissue, resulting in increased bone fragility and fracture risk. Although several drugs such as bisphosphonates, estrogen replacement treatment, and selective estrogen receptor modulators have been used to treat osteoporosis, all these are not the ideal drugs because of insufficient curative ability and adverse side effects. Recently, atorvastatin has ordinarily been prescribed as an anti-hyperlipidemia drug, not as an anti-osteoporosis drug. However, its clinical outcome and potential treatment mechanism are still unclear. In this study, the bilateral ovariectomy of rabbits was duplicated to develop osteoporosis animal model. The effect of atorvastatin on in vivo was determined, and the functional mechanism was studied in vitro after the curative effect was explored. Atorvastatin was observed to significantly increase the mechanical parameters such as maximum load, stiffness, and energy-absorbing capacity, and it improved the microarchitecture. The anti-osteoporosis activity of atorvastatin may be the result of the promotion of differentiation of osteoblasts by inducing synthesis of vascular endothelial growth factor, bone morphogenetic protein 2 (BMP2), core-binding factor alpha 1 (CBFα1), and inhibition of osteoclast formation through the osteoprotegerin (OPG)-receptor activator for the nuclear factor κB ligand (RANKL) system. Our study observations give reliable experimental evidence for clinical application of atorvastatin to treat the disorder of osteoporosis.
Background The prevalence of drug-related problems in patients hospitalized at respiratory care units is unknown in mainland China. Objective To identify and categorize drug-related problems in a respiratory care unit in China. Setting Respiratory care unit in a tertiary university hospital in China. Methods Clinical pharmacy services were introduced and documented during an 18-months study period. The problems were categorized using the Pharmaceutical Care Network Europe DRP classification tool V8.02. Main outcome measures Problems and causes of drug-related problems, interventions proposed, and outcome of pharmacy recommendations. Results A total of 474 patients were reviewed, 164 patients had DRPs (34.6%). Total 410 problems were identified, an average of 2.5 per patient. Treatment effectiveness was the major type of problem detected (219; 53.4%) followed by treatment safety (140; 34.1%). The most common causes of the problems were patientrelated (25.8%), drug selection (24.0%), and drug use process (23.4%). Pharmacist made 773 interventions; average 1.9 per drug-related problem. A total of 96.2% of these interventions were accepted leading to solving 81.9% of the identified problems. Conclusion There is a high prevalence of drug-related problems in patients hospitalized at the respiratory unit of this clinic. Clinical pharmacists should focus on improving prescribing practice and patient counseling.
AimTo evaluate the factors influencing suspected hypersensitivity and adverse systemic reactions after Shuxuening injection and to provide innovative ideas and methods for the reevaluation of post-marketing safety of Shuxuening.MethodsThis study used a prospective, nested case–control study design, combined with a prescription sequence analysis design method. It classified patients who exhibited trigger signals after administration of Shuxuening injection as suspected allergic patients and made comparisons with patients who did not report adverse effects to calculate the correlation between relevant risk factors and suspected allergic reactions. Randomized controlled studies and cohort studies of the adverse drug reaction (ADR) of Shuxuening were performed using a computer database. Data retrieval was carried out by the foundation governing the individual database. Meta-analysis was performed by using R3.2.3 software to evaluate the ADRs of Shuxuening.ResultsThe results of real-world study showed that administration of Shuxuening in combination with potassium aspartate and magnesium, atorvastatin calcium, Shengmai injection, pantoprazole sodium, or high-dose medication was a risk factor for suspected allergic reactions. Meta-analysis showed that the incidence of adverse events was 5.84% (95% CI 0.0499; 0.0674), and serious adverse reaction rate was 4.36% (95% CI 0.0188; 0.0760) when Shuxuening was used in combination with these drugs. The incidence of allergic reaction was also influenced by the vehicle, duration of treatment, single dose, and indicated vs off-label use.ConclusionRisk factors for adverse reaction following the use of Shuxuening injection in patients are associated with a single dose, vehicle, type of disease, and combination with potassium aspartate, atorvastatin calcium, Shengmai injection, injection with pantoprazole sodium, and other drugs. Physicians should be careful to follow guidelines when administering this drug. We further propose that the unique methodology used in this study may be useful for reevaluation of the safety of other traditional Chinese medicines.
