Project description:BackgroundA restrictive use of episiotomy was recommended by the obstetric society in China, but limited information on the epidemiology and the effects of restrictive use of episiotomy on maternal and fetal outcomes have been published.MethodsThe China Labor and Delivery Survey is a cross-sectional investigation with a cluster random sampling scheme in 2015-2016 with the aim to describe detailed epidemiology of labor and delivery in China. We calculated the episiotomy rate by parity using the survey data. Associated factors of episiotomy were selected using mixed models with a random effect for the hospital-level clustering. Logistic regression models were fitted to examine the effects of mediolateral episiotomy on maternal and neonatal outcomes among the propensity score-matched women.FindingsThe episiotomy rate among vaginal births was 41·7% [95% confidence interval (CI): 40·1% - 43·2%] in nulliparae and 21·5% (95% CI: 19·4% - 23·5%) in multiparae in China. Associated factors of episiotomy included prepregnancy BMI, maternal diseases, and obstetric factors. More than half of episiotomies in nulliparae and one-fourth in multiparae had no indications. Mediolateral episiotomy without indicators increased the risk of 3rd or 4th degree perineal laceration [odds ratio (OR) =2·64, 95% CI: 1·08-6·48)] in nulliparae without neonatal benefits.InterpretationEpisiotomy was performed more than medically necessary in China. Mediolateral episiotomy without indications more than doubled the risk of 3rd and 4th degree perineal laceration in nulliparae without neonatal benefits.FundingNational Natural Science Foundation of China and Shanghai Health Commission Programme.
Project description:BackgroundThe World Health Organization reported in 2011 that irrational use of medicines was a serious global problem that is wasteful and harmful. The worst is use of ineffective or harmful interventions which should not be used at all. However, little is known about the changes that 20 years of evidence-based medicine has made particularly in reducing use of ineffective interventions. We surveyed clinicians in China to show how often ineffective interventions were still used in practice.Methods3,246 clinicians from 24 tertiary hospitals were surveyed in person and another 3,063 through an online survey between 2006-2007. The main outcomes are prescription by a clinician, and use in a patient of, an ineffective intervention and of a matched effective intervention in patients with the same disease. 129 ineffective interventions for 68 diseases were identified from the BMJ Clinical Evidence and included in the survey. One effective intervention was identified for each disease and a total of 68 effective interventions were thus also included. The frequency of use of effective interventions was used as a reference for that of ineffective intervention.ResultsThe mean prescription rate by clinicians is 59.0% (95% confidence interval (95% CI): 58.6% to 59.4%) and 81.0% (95% CI: 80.6% to 81.4%) respectively for ineffective and effective interventions. The mean frequency of use in patients is 31.2% (95% CI: 30.8% to 31.6%) and 56.4% (95% CI: 56.0% to 56.8%) for ineffective and effective interventions respectively. The relative reduction in use of ineffective interventions as compared with that of matched effective interventions is 27.2% (95% CI: 27.0% to 27.4%) and 44.7% (95% CI: 44.3% to 45.1%) for clinician's prescription and use in patients respectively. 8.6% ineffective interventions were still routinely used in practice.ConclusionsIneffective interventions were still commonly used. Efforts are necessary to further reduce and eventually eliminate ineffective interventions from practice.
Project description:Paediatric movement disorders (PMDs) comprise a large group of disorders (tics, myoclonus, tremor, dystonia, chorea, Parkinsonism, ataxia), often with mixed phenotypes. Determination of the underlying aetiology can be difficult given the broad differential diagnosis and the complexity of the genotype-phenotype relationships. This can make the diagnostic process time-consuming and difficult. In this overview, we present a diagnostic approach for PMDs, with emphasis on genetic causes. This approach can serve as a framework to lead the clinician through the diagnostic process in eight consecutive steps, including recognition of the different movement disorders, identification of a clinical syndrome, consideration of acquired causes, genetic testing including next-generation sequencing, post-sequencing phenotyping, and interpretation of test results. The aim of this approach is to increase the recognition and diagnostic yield in PMDs. WHAT THIS PAPER ADDS: An up-to-date description and diagnostic framework for testing of paediatric movement disorders is presented. The framework helps to determine which patients will benefit from next-generation sequencing.
Project description:BackgroundTo explore current status and choices regarding diagnosis and treatment of Parkinson's disease (PD) among physicians, general neurologists and movement disorders specialists in China via a national survey.MethodsThe cross-sectional questionnaire-based survey was conducted from November, 2010 to July, 2011. Six hundreds and twelve doctors from different cities in China were recruited for this study.Results68.6% (n=420) and 23.9% (n=146) of doctors have read the national and international guidelines, respectively. There was a larger proportion of movement disorders specialists reading the guidelines, in contrast to physicians and general neurologists (P<0.001). Up to 76.4% (n=465) and 81.8% (n=498) of doctors would choose standard oral levodopa test and conventional MRI(with T1 and T2), respectively; Whereas susceptibility weighed imaging(SWI)(16.1%; n=98), transcranial sonography (TCS) (1.8%; n=11) and functional neuroimaging test, such as single photon emission computed tomography(SPECT) (10.2%; n=62) and positron emission tomography(PET)(13.3%; n=81) were less used for suspected patients with PD in clinical practice. Doctors at different levels or from different hospitals and cities would choose different medication for motor complications and non-motor symptoms of patients with PD, in addition to initial drug selection for newly diagnosed PD. Doctors who had read the guidelines had significantly better knowledge of medication selections for PD under specific circumstances.ConclusionsCompared with commonly employed standard oral levodopa test and conventional MRI, SWI complements MRI, TCS and functional neuroimaging were less performed for diagnosis of PD in clinical practice in China. The choices of diagnostic methods and therapeutic strategy of PD vary among physicians, general neurologists and movement disorders specialists. Guideline awareness is markedly beneficial to reasonable PD medications strategy in China.
Project description:BackgroundTic disorders belong to the broad spectrum of pediatric and adult movement disorders. The wide variability in clinical presentations, applied assessment tools, and treatments are poorly understood.ObjectivesTo map practices and knowledge base of movement disorder clinicians concerning clinical features, pathophysiology, and treatment approaches in tic disorders.MethodsA 33-item survey was developed by the Tic Disorders and Tourette syndrome Study Group members of the Movement Disorder Society. The survey was distributed to the complete society membership and included responses from 346 members, 314 of whom reported treating tic disorders.ResultsApproximately one third of survey respondents (35%) frequently evaluated patients with tics. The data revealed widespread use of existing guidelines (about 70%) and screening for comorbid disorders (>90%). The most common investigations used to rule out secondary causes of tics were imaging (92%), laboratory tests (66%) and neurophysiology (38%). Functional tics were the second most common tic etiology following primary tics. Only 27% of respondents reported confidence in knowledge about tic pathogenesis. Top rated interventions to treat tics were psychoeducation, cognitive behavioral intervention for tics (CBIT) and treatment for neuropsychiatric comorbidities. Antipsychotics were ranked as the most effective pharmacologic tic intervention.ConclusionsThe majority of movement disorders specialists do not frequently encounter tics. There was sparse knowledge about tic pathophysiology. Psychoeducation, CBIT, the treatment of neuropsychiatric comorbidities and use of antipsychotics emerged as the most common interventions to treat tics. These results provide insight into what will be needed to improve the diagnosis and treatment of tic disorders.
Project description:Proper diagnosis and treatment of traumatic brain injury (TBI) in children is becoming an increasingly problematic issue in China. This study investigated Chinese clinicians to provide information about their knowledge and experiences in diagnosis and treatment of pediatric TBI. We conducted a questionnaire survey among clinicians in the emergency departments and neurosurgery departments at 9 major hospitals in China. The questionnaire included demographic information, and knowledge and experiences regarding the diagnosis and treatment of pediatric TBI. A total of 235 clinicians completed questionnaires. 43.8% of the surveyed clinicians reported children with only scalp hematoma without any other signs and symptoms of concussion as TBI cases. Most clinicians (85.1%) reported no existing uniform diagnostic criteria for children with TBI in China. The majority of clinicians (91.9%) reported that CT scans were performed in all patients with suspected head injury as a routine procedure in their hospitals. Only 20.9% of clinicians believed that radiation from CT scanning may increase cancer risk in children. About 33.6% of the clinicians reported that they ordered CT scans to investigate suspected head injury due to the poor doctor-patient relationship in China, and to protect themselves against any medical lawsuits in the future. About 80% of the clinicians reported that there are no existing pediatric TBI treatment guidelines in China. Instead a senior doctor's advice is the most reported guidelines regarding treating pediatric TBI (66.0%). All of the surveyed clinicians reported that the lack of diagnosis and/or treatment standard is the biggest problem in effectively diagnosing and treating pediatric TBI in China. Developing guidelines for the diagnosis and treatment of children with TBI is a high priority in China. The extremely high usage of CT for pediatric TBI in China suggests that it is important to establish evidence-based clinical decision rules to help Chinese clinicians make diagnostic and therapeutic decisions during their practice in order to identify children unlikely to have a clinically-important TBI who can be safely discharged without a CT scan.
Project description:Background: Functional (psychogenic) movement disorders often have distinguishable clinical features in the orofacial region. Tonic mandibular deviation accompanying ipsilateral downward and lateral lip pulling is the most common phenotype seen in patients with facial functional movement disorders. However, functional movement disorders in the stomatognathic system are underrecognized. Objective: This study aimed to evaluate clinical characteristics and phenomenology in patients with functional movement disorders in the stomatognathic system. Methods: Ten-item inclusion criteria (point range: 0-10) for functional movement disorders in the stomatognathic system was produced, based on previously established criteria for functional movement disorders and general signs of functional facial dystonia, to determine subject inclusion. The criteria included inconsistency, incongruence, and paroxysm in symptoms; rapid onset; distractibility; suggestibility; static course; spreading to multiple sites; spontaneous remission; and lack of sensory tricks. Fifty-eight patients [42 women (72.4%), 16 men (27.6%); mean age: 46.2 years] scored over 7 points on the criteria and were included in further analyses. Characteristic features, including the pattern and site of abnormal movements, were assessed in clinical examination. Results: Frequent items in the scale were inconsistent symptoms (93.1%), incongruous symptoms (91.4%), spreading to multiple sites (89.7%), paroxysmal symptoms (86.2%), and lack of sensory tricks (81%). Sixty percent of patients exhibited a pattern resembling dystonia. Some patients had a combination of organic and functional disease. Common involuntary movements included jaw deviation (74.1%), jaw closing (50%), lip pulling (34.5%), and tongue movement (31%). A functional dystonia phenotype (unilateral lower lip pulling and jaw deviation) was observed in 26 patients (44.8%). Characteristic features of functional stomatognathic movement disorders were rapidly repeating mandibular (lateral or tapping) and tongue movements (27.6%), which fluctuated in speed and direction. Conclusion: In 58 patients with functional movement disorders in the stomatognathic system, the functional dystonia phenotype was observed in 44.8%. Furthermore, 27.6% of patients showed the most characteristic type of functional stomatognathic movement disorders: very fast repeated jaw and/or lingual movements.
Project description:Background/aimsEsophageal high-resolution manometry (HRM) enables the comprehensive evaluation of the esophageal motor function. However, protocols are not uniform and clinical practices vary widely among institutions. This study aims to understand the current HRM practice in Korea.MethodsThe survey was sent via email through the Korean Society of Neurogastroenterology and Motility. The questions covered descriptive information, preparation, techniques, analysis, and reporting of esophageal HRM.ResultsThe survey was completed in 32 (74.4%) out of 43 centers, including 24 tertiary and 8 secondary referral centers. Of the 32 centers, 25 (78.1%) performed HRM in a sitting position, while 7 centers (21.9%) reported performing HRM in a supine position. All the centers utilized single wet swallows as a standard, but the volume, frequency, and interval between swallows varied widely. Sixteen centers (50.0%) applied adjunctive tests, including multiple rapid swallows (n = 16) and rapid drink challenges (n = 9). Parameters assessed and documented in the report were similar. In addition to the assessment of the esophagogastric junction and esophageal body, 27 centers (84.8%) and 18 centers (56.3%) included measurements for the upper esophageal sphincter and the pharynx, respectively, in the HRM protocol.ConclusionsWe found a variation in the available HRM practice among centers, even though they broadly agreed in the data analysis. Efforts are needed to develop a standardized protocol for HRM measurement.
Project description:Background:Functional movement disorders (FMDs) have been rarely described in the elderly population. Methods:This is a retrospective chart review of elderly patients with FMDs (onset >60 years) attending the movement disorders clinic at a tertiary care teaching institute in India. Results:Out of 117 patients diagnosed with FMD at our center, 18 patients had an onset after the age of 60 years. The male-to-female ratio was 10:8 and the duration of symptoms ranged from 1 day to 5 years. Social (10/18) and physical factors (5/18) with an evident temporal relationship with the onset of FMD were identified in 15 out of 18 patients. Six of them had a past history of depression, anxiety, or other psychiatric illnesses. The tremor was the most frequent phenomenology seen in 11 (61.1%) patients, followed by dystonia in seven (38.8%), choreoballism and tics in two each, and hemifacial spasm and functional gait in one each. Seven patients had more than one phenotype. Discussion:Tremor was the most frequent movement disorder seen in our patients with FMD. Surprisingly, tics (n = 2) and choreoballistic (n = 2) movements were also found in our patients with FMD, which has not been reported previously in an elderly population. Both physical and social factors were identified preceding the development of FMDs in majority of our patients.
Project description:ObjectivesTo investigate the airway management equipment and clinical practice in emergency department wards in China, and to explore the factors that influenced the nurses' airway management practice.DesignCross-sectional study.SettingA nationwide survey covering the seven administrative regions of China (North China, Northeast China, East China, Central China, South China, Southwest China and Northwest China).ParticipantsThe nurses had to be registered nurses who worked in adult emergency department wards of the selected hospitals.MeasuresAn online survey was designed, piloted and distributed to the members of the Emergency Medicine Committee of the Chinese Nursing Association, and the nurses from the members' hospitals were invited to participate. The questionnaire was used to determine nurses' clinical practice scores of airway management in emergency wards.ResultsFinally, we collected 995 valid questionnaires from 31 provinces and 143 districts in China. Among them, 361 (36.28%) nurses responded that their departments used open suction system (OSS) in clinical work, the major barrier for closed suction system (CSS) reported by 630 respondents (63.32%) was cost. Significant differences in all three scores were found in age, nursing experience years, technical title, airway management training experience and nursing specialist (all p<0.05). Correlations were found among airway management attitude, practice of sputum aspiration and practice of ventilator care bundles (r=0.655, r=0.543 and r=0.763, all p<0.001).ConclusionsChinese emergency department managers need to identify better methods for assessing equipment availability in OSS. CSS can be a choice when costs, status of the individual patient and severity of disease are comprehensively considered. Emergency department nurses' scores of airway management practice were affected by demographic and job-related characteristics; regular training should be encouraged, and equipment and resources should be guaranteed to improve airway management quality and optimise patient outcomes.
