RESUMO

BACKGROUND: Digital interventions have potential to efficiently support improved hygiene practices to reduce transmission of COVID-19. OBJECTIVE: To evaluate the evidence for digital interventions to improve hygiene practices within the community. METHODS: We reviewed articles published between 01 January 2000 and 26 May 2019 that presented a controlled trial of a digital intervention to improve hygiene behaviours in the community. We searched MEDLINE, Embase, PsycINFO, Cochrane Controlled Register of Trials (CENTRAL), China National Knowledge Infrastructure and grey literature. Trials in hospitals were excluded, as were trials aiming at prevention of sexually transmitted infections; only target diseases with transmission mechanisms similar to COVID-19 (e.g. respiratory and gastrointestinal infections) were included. Trials had to evaluate a uniquely digital component of an intervention. Study designs were limited to randomised controlled trials, controlled before-and-after trials, and interrupted time series analyses. Outcomes could be either incidence of infections or change in hygiene behaviours. The Risk of Bias 2 tool was used to assess study quality. RESULTS: We found seven studies that met the inclusion criteria. Six studies reported successfully improving self-reported hygiene behaviour or health outcomes, but only one of these six trials, Germ Defence, confirmed improvements using objective measures (reduced consultations and antibiotic prescriptions). Settings included kindergartens, workplaces, and service station restrooms. Modes of delivery were diverse: WeChat, website, text messages, audio messages to mobiles, electronic billboards, and electronic personal care records. Four interventions targeted parents of young children with educational materials. Two targeted the general population; these also used behaviour change techniques or theory to inform the intervention. Only one trial had low risk of bias, Germ Defence; the most common concerns were lack of information about the randomisation, possible bias in reporting of behavioural outcomes, and lack of an analysis plan and possible selective reporting of results. CONCLUSION: There was only one trial that was judged to be at low risk of bias, Germ Defence, which reduced incidence and severity of illness, as confirmed by objective measures. Further evaluation is required to determine the effectiveness of the other interventions reviewed. TRIAL REGISTRATION: PROSPERO CRD42020189919 .

RESUMO

BACKGROUND: Shufeng Jiedu capsule has been widely used in China for acute upper respiratory tract infections (AURTIs). The aim of this study was to evaluate its effectiveness and safety for AURTIs. METHODS: Randomized controlled trials comparing SFJD with conventional drug for patients with AURTIs were included. Eight databases were searched from their inceptions to February 2021. Data was synthesized using risk ration (RR) or mean difference (MD) with their 95% confidence interval (CI). The primary outcome was resolution time of typical symptoms. RESULTS: Twenty-five RCTs involving 3410 patients were included. SFJD in combination with conventional drug was associated with; in common cold shortening the duration of fever (MD -1.54 days, 95% CI [-2.15,-0.92], I 2 = 80%, n = 385, 3 trials) and cough (MD -1.22 days, 95% CI [-1.52, -0.93]); in herpangina, shortening the duration of fever (MD -0.68 days, 95% CI [-1.15, -0.21], I2  = 68%, n = 140, 2 trials) and blistering (MD -0.99 days, 95% CI [-1.23, -0.76], n = 386, 3 trials); in acute tonsillitis and acute pharyngitis shortening the duration of fever (MD -1.13 days, 95% CI [-1.36, -0.90], I 2 = 33%, n = 688, 7 trials) and sore throat (MD -1.13 days, 95% CI [-1.40, -0.86], I 2 = 84.1%, n = 1194, 10 trials). SFJD also improving their cure rate with a range (1-5 days). No serious adverse events were reported. CONCLUSION: Low certainty evidence suggests that SFJD appears to shorten the duration of symptoms in AURTIs, improve cure rate and seems safe for application. However, high quality placebo controlled trials are warranted to confirm its benefit.

RESUMO

BACKGROUND: Chinese herbal medicine is widely used in combination with usual care for acute exacerbations of chronic obstructive pulmonary disease (AECOPD) in China. Chinese patent medicine Shufeng Jiedu (SFJD) capsules is widely used for respiratory infectious diseases. This review aims to evaluate effectiveness and safety of SFJD for AECOPD. METHODS: A systematic review of randomised controlled trials (RCTs) in patients with AECOPD, who received SFJD as a single intervention or as add-on treatment to usual care. PubMed, the Cochrane Library, EMBASE, Scopus, Web of Science and four Chinese databases were searched from inception to April 2019. Two authors screened trials, extracted data, and assessed risk of bias, independently. Meta-analysis was performed using RevMan 5.3 software. We performed subgroup analyses and sensitivity analyses according to the predefined protocol. Quality of evidence was assessed using GRADE. RESULTS: Thirteen RCTs (1036 patients, with 936 inpatients) were included, all compared SFJD in combination with usual care (including antibiotics) to usual care alone. The mean age of participants ranged from 52 to 67 years, with approximately 60% male. Due to lack of blinding and other factors, all trials were of high risk of bias. SFJD was associated with a significant reduction in treatment failure, from 20.1 to 8.3% (11 trials; 815 patients; relative risk 0.43, 95% confidence interval [CI] 0.30 to 0.62), and duration of hospital stay (2 trials; 79 patients; mean difference - 4.32 days, 95% CI - 5.89 to - 2.75 days). No significant difference in adverse events was found between SFJD and control groups. CONCLUSION: Low certainty evidence suggests SFJD may bring additional benefit in reducing treatment failure, shorten hospital stay, and improving symptoms. Further large, high quality RCTs are needed to confirm its benefit and safety. TRIAL REGISTRATION: PROSPERO CRD42019133682.

RESUMO

The purpose of the study is to analyze the outcomes of randomized controlled trial(RCT) of Chinese herbal medicine formula(CHMF) in the treatment of vascular cognitive impairment caused by cerebral small vessel disease(CSVD-VCI), and provide suggestions for future studies in this field. Three English databases, four Chinese databases, and two online registration websites of clinical trials were searched with use of the search strategy established in advance. Relevant RCTs published in recent ten years were screened, and necessary information was extracted to assess the risk of bias and analyze the outcomes of these RCTs. As a result, a total of 10 461 articles were retrieved, of which 8 681 were kept after de-duplication, and 41 RCTs were included after screening, with a generally higher risk of bias. The outcomes of included RCTs were classified into 9 categories, namely, clinical symptom outcomes, neuroimaging outcomes, neuroelectrophysiological outcomes, blood biochemical outcomes, hemorheology outcomes, physical signs, syndrome scores of traditional Chinese medicine(TCM), clinical effective rate, and safety outcomes. Among them, the most frequently reported outcomes of included RCTs were blood biochemical outcomes, and clinical symptom outcomes showed the highest reporting rate. Besides, 9 RCTs reported syndrome scores of TCM as the outcomes and illustrated corresponding evaluation criteria. The analysis showed that the application of RCT outcomes in this field had clinical rationality and limitations, and there were also some deficiencies in the trial design level, namely, no distinction between primary and secondary outcomes, insufficient blind methods, not detailed description of outcomes, disunity of evaluation tools, and despised endpoint outcomes. These limitations and deficiencies were negatively affecting the quality of RCTs of CHMF in the treatment of CSVD-VCI. Therefore, we suggest that future researchers should be well prepared in the top-level design stage, and actively construct the core outcome set of this field, so as to improve the quality of clinical trials.

RESUMO

Sanfu acupoint herbal patching (SAHP) is a unique traditional Chinese medicine therapy, which has become popular for preventing acute attack of respiratory diseases such as asthma and chronic obstructive pulmonary disease, in many regions of mainland China. However, the knowledge about its users is lacking, especially the characteristics of the users and their experience and perspectives.To investigate the demographics of users, conditions for its use and the previous experience of SAHP, as well as users' perspectives to provide baseline information for its practice.A cross-sectional consecutive-sample survey was conducted at outpatient departments from 3 traditional Chinese medicine hospitals in northern China. Each participant completed a questionnaire, after informed consent. Data description and analyses were done using SPSS 20.0.Among 949 SAHP users from 3 hospitals, female was predominant (n = 592; 62.4%), aged from 2 to 96 years (median = 52 years). 64.7% (380/587) of regular users have applied consecutively for 3 years or over, and the self-perceived satisfaction rates of respiratory diseases were from 45.9% to 77.7%. Positive attitude toward traditional Chinese medicine was the top reason for choosing SAHP. 42.4% of users held a motivation of being cured by SAHP and with great outcome expectancy on SAHP (70.8%).SAHP users were mainly female adults or elderly population; more than half were regular users, who predominantly used SAHP for various chronic respiratory diseases during their stable stage. The majority of users expressed satisfaction to previous SAHP for their respiratory diseases. 42.4% of users held a motivation of being cured by SAHP and with great outcome expectancy on SAHP (70.8%). The findings from this survey deserve further clinical trials for their clinical effectiveness.
