Rare diseases in China: analysis of 2014-2015 hospitalization summary reports for 281 rare diseases from 96 tertiary hospitals.

ABSTRACT: BACKGROUND:There are many public health issues to resolve regarding rare diseases, including a lack of data from large-scale studies. The objective of this study was to explore fundamental data for a list of rare diseases in China, based on a hospitalization summary reports (HSRs) database. The Target Rare Diseases List (TRDL) 2017 was generated using an expert consensus method in which experts listed diseases according to research priorities. Using codes of the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) and key search terms of rare diseases in English and Chinese, data were obtained from HSRs of 96 hospitals, covering a population of over 15 million in China from 2014 to 2015. We extracted and analyzed information on demographics, hospitalizations, and readmissions. RESULTS:A total 281 rare diseases were included in the TRDL 2017. Altogether, 106,746 hospitalizations for a rare disease were captured from 1 January 2014 to 31 December 2015, accounting for 0.69% of inpatients during the same period. The top 10 rare diseases with most cases on the TRDL 2017 were thalassemia, idiopathic pulmonary arterial hypertension, pulmonary Langerhans cell histiocytosis, moyamoya disease, motor neuron disease, idiopathic pulmonary fibrosis, systemic sclerosis, hepatolenticular degeneration, coarctation of the aorta, and transposition of the great arteries. Among the 24 cities in the database, the five cities with the most types of the rare disease were Beijing, Changsha, Guangzhou, Shanghai, and Chengdu, with 191, 162, 143, 141, and 133 types, respectively. The five cities with most cases of the 281 rare diseases were Beijing, Guangzhou, Shanghai, Nanning, and Chengdu. The age distribution of rare diseases was 52% for the age group 25-64?years, and 27% of cases in the age group of 0-14?years were among children. The 10 highest readmission rates ranged from 35 to 65%. CONCLUSIONS:This study provided the TRDL 2017 and descriptive analysis of 281 rare diseases in a hospitalized population. Our study reveals important fundamental information that will be useful in national policy making and legislation; registry implementation; and diagnosis, treatment, and prevention of rare diseases in China.

Project description:In the absence of reliable data on the burden of hepatitis E virus (HEV) in high endemic countries, we established a hospital-based acute jaundice surveillance program in six tertiary hospitals in Bangladesh to estimate the burden of HEV infection among hospitalized acute jaundice patients aged ?14 years, identify seasonal and geographic patterns in the prevalence of hepatitis E, and examine factors associated with death. We collected blood specimens from enrolled acute jaundice patients, defined as new onset of either yellow eyes or skin during the past three months of hospital admission, and tested for immunoglobulin M (IgM) antibodies against HEV, HBV and HAV. The enrolled patients were followed up three months after hospital discharge to assess their survival status; pregnant women were followed up three months after their delivery to assess pregnancy outcomes. From December'2014 to September'2017, 1925 patients with acute jaundice were enrolled; 661 (34%) had acute hepatitis E, 48 (8%) had hepatitis A, and 293 (15%) had acute hepatitis B infection. Case fatality among hepatitis E patients was 5% (28/589). Most of the hepatitis E cases were males (74%; 486/661), but case fatality was higher among females-12% (8/68) among pregnant and 8% (7/91) among non-pregnant women. Half of the patients who died with acute hepatitis E had co-infection with HAV or HBV. Of the 62 HEV infected mothers who were alive until the delivery, 9 (15%) had miscarriage/stillbirth, and of those children who were born alive, 19% (10/53) died, all within one week of birth. This study confirms that hepatitis E is the leading cause of acute jaundice, leads to hospitalizations in all regions in Bangladesh, occurs throughout the year, and is associated with considerable morbidity and mortality. Effective control measures should be taken to reduce the risk of HEV infections including improvements in water quality, sanitation and hygiene practices and the introduction of HEV vaccine to high-risk groups.

Project description:BackgroundChina has a high rate of antibiotic use. The Chinese Ministry of Health (MOH) established the Center for Antibacterial Surveillance (CAS) to monitor the use of antibacterial agents in hospitals in 2005. The purpose of this study was to identify trends, pattern changes and regional differences in antibiotic consumption in 151 public general tertiary hospitals across China from 2011-2014.Materials and methodsValid data for antibiotic use were collected quarterly, and the antibiotic consumption data were expressed as the defined daily dose (DDD) per 100 inpatient days (ID). We compared the patterns of antibiotic use in different classes and geographical clusters.ResultsTotal antibiotic use significantly decreased (P = 0.018) from 75.86 DDD/100 ID in 2011 to 47.03 DDD/100 ID in 2014. The total consumption of flomoxef sodium and cefminox increased from 1.31 DDD/100 BD in 2011 to 8.6 DDD/100 BD in 2014. Cephalosporins were the most frequently used antibiotics in all regions. Third-generation cephalosporins accounted for more than 45% of the cephalosporins used. Carbapenem use substantially increased (P = 0.043). Penicillin combinations with inhibitors accounted for 50% of the penicillin used, and prescribed meropenem accounted for most of the carbapenems used in all regions in 2014. The subclasses in each antibiotic group were used differently between the seven regions, and the total hospital antibiotic use in 2014 differed significantly by region (P = 0.014).ConclusionAlthough the volume and intensity of total antibiotic use decreased, the antibiotic use patterns were not optimal, and broad-spectrum antibiotics were still the main classes. The aggregate data obtained during the study period reveal similar antibiotic consumption patterns in different regions. These findings provide useful information for improving the rational use of antibiotics. More detailed data on antibiotics linked to inpatient diseases need to be collected in future studies.

Project description:Background:Infectious diseases consultant (IDC) pharmacists work within an IDC service to care for inpatients with complex infections. With Accreditation Canada's new Required Organizational Practice promoting the establishment of antimicrobial stewardship (AMS) programs, AMS pharmacists are being employed in acute care hospitals. There is potential for overlap in responsibilities between IDC and AMS pharmacists, but there is no literature outlining the current duties for each group in Canada. Objective:To describe the demographic characteristics and roles of IDC and AMS pharmacists in Canadian tertiary care academic hospitals. Methods:A survey of IDC and AMS pharmacists at Canadian tertiary care academic hospitals was conducted between February and April 2015. The questionnaire included questions about the pharmacist's experience, education, and training; the institution where the pharmacist was practising; the IDC or AMS team characteristics; and the pharmacist's roles in clinical, educational, administrative, and research sectors. Results:The survey response rate was 77% (68/88). The 68 respondents self-identified as IDC pharmacists (14 [21%]), AMS pharmacists (34 [50%]), or dual-role IDC and AMS pharmacists (20 [29%]). Compared with AMS pharmacists, IDC pharmacists reported more of the following unique clinical activities: directly communicating with patients, attending rounds, involving patients in decision-making, and providing patient education. The 3 groups of pharmacists described similar educational responsibilities. The AMS pharmacists performed more of the following administrative and research duties: development of antibiograms and preprinted orders, collection of antimicrobial metrics, and drug-use evaluations for antimicrobials. Dual-role IDC and AMS pharmacists were involved in fewer of the unique activities described by those who practised within a single subspecialty. Conclusions:Self-identified IDC and AMS pharmacists in Canadian tertiary care academic hospitals were performing many similar roles; however, distinct differences within the clinical, administrative, and research domains were identified among IDC pharmacists, AMS pharmacists, and those who identified as dual-role IDC and AMS pharmacists.

Project description:BACKGROUND:The purpose of the study is to discuss the correlation between the resistance rate of gram negative bacteria to fluoroquinolones (FQ) and antibiotic consumption intensity of 145 China tertiary hospitals in 2014. METHODS:This retrospective study adopted national monitoring data from 2014. Each participating hospital required to report annual consumption of each antibiotic, and the resistance rate of gram negative bacteria to FQ. Then the correlation between antibiotic usage and fluoroquinolones -resistant (FQR) rate was consequently investigated. RESULTS:One hundred forty-five hospitals were included in the study, and the median antibiotic consumption intensity was 46.30 (23.93-115.39) defined daily dosages (DDDs) per 100 patient-days. Cephalosporins ranks first in the antibiotics consumption, followed by fluoroquinolones, penicillins, and carbapenems. Fluoroquinolones resistance rate varied from hospital to hospital. The correlation analysis showed significant relationship between the percentage of FQR Escherichia coli and the consumption of FQs (r?=?0.308, p<0.01) and levofloxacin (r?=?0.252, p<0.01). For FQR Klebsiella pneumoniae, not only FQs (r?=?0.291, p<0.01) and levofloxacin (r?=?0.260, p<0.01) use but also carbapenems (r?=?0.242, p<0.01) and overall antibiotics (r?=?0.247, p<0.01) use showed significant correlation. The resistant proportion of FQR Pseudomonas aeruginosa was observed to be correlated with the consumption of all antibiotics (r?=?0.260, p<0.01), FQs (r?=?0.319, p<0.01) and levofloxacin (r?=?0.377, p<0.01). The percentage of levofloxacin-resistant Acinetobacter baumannii was significantly correlated with the consumption of all antibiotics (r?=?0.282, p<0.01), third-generation cephalosporins excluding combinations with beta-lactamase inhibitors (r?=?0.246, p<0.01), FQs (r?=?0.254, p<0.01) and levofloxacin (r?=?0.336, p<0.01). However, the correlation of the ciprofloxacin-resistant A. baumannii and the antibiotics consumption was not found. CONCLUSIONS:A strong correlation was demonstrated between the antibiotic consumption and the rates of FQR gram-negative bacteria. As unreasonable antibiotics usage remains crucial in the proceeding of resistant bacteria selection, our study could greatly promote the avoidance of unnecessary antibiotic usage.
