This study demonstrates a low anti-osteoporosis drug treatment rate (22.1% in women, 9.5% in men) after osteoporotic fracture in the real-world setting of Fujian, China. The primary medication was calcitonin. The suboptimal treatment was particularly critical among men, low-level hospitals, wrist/vertebral fracture, and the younger elderly patients.
The objective of this study was to investigate the prescription patterns and related influencing factors of anti-osteoporosis drug prescribing after osteoporotic fracture in Fujian, China, between 2010 and 2016.
This is a retrospective cohort study based on an existing electronic health record database (National Healthcare Big Data in Fuzhou, China, 37 hospitals included). Patients over 50 years old with newly diagnosed osteoporotic fractures between 2010 and 2016 were included. Postfracture osteoporosis therapies were summarized by overall and fracture site. Multivariate logistic regression was performed to identify influencing factors of anti-osteoporosis medication (AOM) prescription.
Overall, 22.1% of women and 9.5% of men over 50 years old received AOM treatment after osteoporotic fracture within 1 year during 2010-2016, with particular low use of bisphosphonates, 5.3% in women and 1.5% in men. The highest rate of AOM treatment was found in patients with hip fracture (24.5%), followed by vertebral fracture (14.2%) and wrist fracture (2.3%). Of the AOM-treated patients, 90.5% received calcitonin therapy. The treatment rate of AOM showed a slight decline during 2010-2016, but steady rise trends were observed in Ca/vitamin D (VD) prescription. Hospital level, age, sex, previous osteoporosis, previous AOM prescription, and previous oral glucocorticoid prescription were strong predicting factors of AOM prescription.
In a real-world setting, AOM treatment was suboptimal and the treatment rate even decreased over time among osteoporosis fracture patients in Fujian, China. The suboptimal treatment was particularly critical among men, low-level hospitals, wrist/vertebral fracture, and the younger elderly patients.

BACKGROUND: We need to monitor patterns of antibiotic prescribing in order to develop and evaluate antibiotic stewardship interventions in rural China. As part of a multidisciplinary study of antibiotic use in Anhui Province we assessed the validity of electronic records (e-records) as a source of surveillance data.
METHODS: One township healthcare centre and one village clinic were selected in each of three different counties. Patients with symptoms of Upper Respiratory Tract Infection (URTI), exacerbation of Chronic Obstructive Pulmonary Disease (COPD) or Urinary Tract Infection (UTI) were recruited consecutively. Researchers observed and documented clinic consultations and interviewed each of the study participants. E-records were compared to clinic observations and patient interviews.
RESULTS: A total of 1030 patients were observed in clinic. Antibiotics were prescribed in 917 (89%) of consultations. E-records were created only for individuals with health insurance, with considerable between-site variation in completeness (0 to 98.7% of clinic consultations) and in the timing of documentation (within-consultation up to weeks afterwards). E-record accuracy was better in relation to antibiotics (82.8% of e-records accurately recorded what was prescribed in clinic) than for diagnosis and symptoms (45.0 and 1.1% accuracy). Only 31 participants (3.0%) presented with UTI symptoms.
CONCLUSIONS: We have confirmed very high rates of outpatient antibiotic prescribing in rural Anhui province. E-records could provide useful information to inform stewardship interventions, however they may be inaccurate and/or biased. Public Health authorities should focus on improving technical infrastructure and record-keeping culture in outpatient settings. Further research is needed into community treatment of UTIs.

Objective. To investigate the contemporary status of stroke risk profile, antithrombotic treatment, and quality-of-life (QoL) of patients with all types of atrial fibrillation (AF) in China. Design. This is a multicenter, cross-sectional study. Setting. Tertiary (80%) and Tier 2 hospitals (20%) were identified in different economic regions (Northeast, East, West, and Middle) by using a simple random sampling. Participants. A total of 3562 (85.6%) patients with nonvalvular atrial fibrillation (NVAF) and 599 (14.4%) with rheumatic valvular atrial fibrillation (VAF) were consecutively enrolled from 111 hospitals from July 2012 to December 2012. Data Collection. Patient information was collected and QoL was assessed using Short-Form 36 Health Survey (SF-36) questionnaire. Primary and Secondary Outcome Measures. The risk of stroke was assessed using the CHADS2 and CHA2DS2-VASc. QoL was assessed using Medical Outcomes Study SF-36 questionnaire. Results. Overall, 31.7% of the patients received anticoagulant treatment and 61.2% received antiplatelet treatment. The rate of anticoagulant treatment was higher in patients with VAF than in those with NVAF. The anticoagulant use was the lowest in Northeast and the highest in Middle regions. Independent risk factors associated with underuse of anticoagulants for NVAF were age, systolic blood pressure (SBP), non-Middle regions, nontertiary hospitals, and new-onset or paroxysmal AF. For VAF patients, the independent factors were age, paroxysmal AF, treatment in Tier 2 hospitals, SBP, diastolic blood pressure, history of coronary artery disease, and nonreceipt of antiarrhythmic therapy. Patients receiving anticoagulants fared significantly better in some QoL domains than those who received no antithrombotic therapy. Conclusions. These findings suggest that antiplatelet treatment is overused and anticoagulant treatment is underused both in Chinese patients with VAF and NVAF, even though usage of anticoagulants is associated with better QoL. Risk factors with underuse of anticoagulants were not identical in patients with NVAF and VAF.

Irrational antibiotic usage not only causes an increase in antibiotic-borne diseases, but also inflicts pain on patients, as a result of inappropriate treatment. In order to resolve the hazards caused by irrational antibiotic usage, a kind of e-health service, the Rational Antibiotic Use System (RAUS), has been incorporated into the hospital information system. The RAUS provides doctors and patients with the functions of antibiotic usage monitoring, antibiotic information consultation and antibiotic prescription support. Though existing literature has already proved the usefulness of the RAUS on monitoring doctors\' behavior, the effects on hospital performance from an organizational perspective has rarely been measured by empirical data. Therefore, our study has explored the effects of the RAUS on the performance of a large Chinese hospital, which has implemented the RAUS since March 2014. Through empirical research, we quantified the effects of the implementation of the RAUS on a hospital\'s performance from both the direct effects on the \"drug income\" and the spillover effect on the \"treatment income\". The results indicate a significant positive spillover effect on the treatment incomes of a hospital in its inpatient activities (seen as significant in the long term) and in its outpatient activities (seen as significant in both the short and long terms). In addition, this research provides certain theoretical and practical implications for the dilemma of e-health services application in irrational antibiotic usage.

BACKGROUND: Problems of irrational antibiotic use by prescribers are ongoing and have escalated following reductions in the cost of essential drugs policy. In an attempt to improve prescribing practices for village doctors and rational use of essential drugs, a program designed to audit and monitor drug use was established. However, the effects of the program to control antibiotic resistance and changing the village doctors\' prescribing behaviors remain largely unknown. This study measured the effect of the program on levels of antibiotic use.
METHODS: Data was collected covering a 22-month period, before, during and after the program was implemented in rural clinics. Segmented regression analysis with interrupted time series (ITS) data was used to examine whether there had been a significant interaction with the onset of the program in September 2011 and levels of antibiotic use from November 2010 to August 2012. Both serial and 12-month lag autocorrelations were controlled for.
RESULTS: A noticeable drop about 6.15% per month (95% CI: -13.36%; 1.06%, P = 0.089) for the antibiotic use in outpatients, which is lower of effect size assuming that the program has the immediate impact of the program were captured for the immediate effect of the program. Meanwhile, levels of antibiotic use would have continued to decrease by 1.12% per month (P = 0.034) as they did in the absence of the program.
CONCLUSIONS: The central finding was that the prescription audit and feedback program was associated with significant decreases (P = 0.034) in antibiotic use after its implementation.

We aimed to describe patterns in the usage of antivirals to treat influenza virus infection in hospitals in Hong Kong from 2000 through 2015.
We analyzed centralized electronic health records that included dispensation information and diagnosis codes. Information collected on admissions included patient age, sex, admission year and month, and medications dispensed, and were matched with the first 15 discharge diagnosis codes. We divided monthly admission episodes by relevant population denominators to obtain admission rates, and stratified analyses by drug type, age group, and diagnosis codes.
Amantadine was used for influenza treatment in the early 2000s but changed with recommendations to avoid its use in 2006, and is now mainly used to treat Parkinson\'s disease. Oseltamivir usage increased substantially in 2009 and is now commonly used, with almost 40,000 hospitalizations treated with oseltamivir in the years 2012 through 2015, 66% of which was in persons ≥65 years of age. During the entire study period, of the 98,253 admission episodes in which oseltamivir was dispensed, 40,698 (41%) included a diagnosis code for influenza, and 80,283 (82%) included any diagnosis code for respiratory illness.
The amount of oseltamivir used from 2012-15 was comparable to a separate ecological estimate of around 13,000 influenza-associated hospitalizations per year on average. We did not have access to individual patient laboratory testing data.

The consumption of antibiotics is a major driver in the development of antimicrobial resistance. This study aims to identify the trends and patterns of the total antibiotic consumption in China\'s tertiary hospitals from 2011 to 2015 by retrospectively analyzing aggregated monthly surveillance data on antibiotic sales made to 468 hospitals from 28 provinces. Antibiotic consumption was expressed in DDD per 1,000 inhabitants per day (DID). We compared population weighted antibiotic consumption patterns in China with European countries using indicators from the European Surveillance of Antimicrobial Consumption (ESAC). Total antibiotic consumption, including all the specific antibiotic class except for aminoglycoside antibacterials, were significantly increased during the study period from an average of 7.97 DID in 2011 to 10.08 DID in 2015. In 2015, the eastern regions of China consumed the most antibiotics using population denominator while the western regions consumed the most using inpatient denominator. Cephalosporins accounted for 28.6% of total DID, followed by beta-lactam-beta-lactamase inhibitor combinations (20.0%), macrolides (17.4%), and fluoroquinolones (10.5%). Antibiotic in parenteral form accounted for nearly half of all antibiotics. Although over the past few years major efforts had been made to reduce the risks of excessive antibiotic use through antibiotic stewardship, total antibiotic consumption showed a significant upward trend during the study period. A consistent preference for cephalosporins, macrolides, beta-lactam-beta-lactamase inhibitor combinations, as well as parenteral preparations was observed.

This is a study based on hospital intensive monitoring to explore medication use of Diemailing Kudiezi injection(one Chinese herbal medicine injection) in real word in the patients with cerebral infarction. The active monitoring model was adopted and hospital intensive monitoring on safety of 7 189 cases of patients with cerebral infarction was conducted to obtain the drug use information of Diemailing injection. The results were analyzed by using statistical description and association rule method. The statistical description and association rule analysis were conducted based on patients\' basic demographic characteristics, use of Diemailing injection and combined use of drugs. Sixty-two percent(4 437/7 189) of the patients were from traditional Chinese medicine hospitals as compared with 39%(2 752/7 189) from western medicine hospitals; 84%(6 003/7 189) of the patients were from tertiary hospitals as compared with 16%(1 186/7 189) from second-class hospitals. The hospitals were mostly located in north China. Drug related indicators such as a single dripping speed, stash time after allocating transfusion, duration of injection, and injecting room temperature were not noted in instruction manual. It was also found that there were off label use in the practice, for instance, non-intravenous infusion, >14 d treatment course, use of non-designated solvent, and a single dose>40 mL or<10 mL. Analysis of association rules showed that only Edaravone among the most frequent combined drugs was listed in the current guideline in China, and the other three most frequent combined drugs deproteinized calf blood extractive injection, Cinepazide Maleate injection and Alprostadil injection were used with little evidence. Diemailing＋Aspirin＋Alprostadil was the most common combined use in our study, but the recommended clopidogrel＋Aspirin was not found in this study. The drug use situation of Diemailing injection in the real world was obtained by data analysis on large size samples, providing basic reference information for clinicians and researchers. However, efficacy was not concerned in this study, so efficacy-related information could not be explained.
