There are about 3753 clinical studies being (or have been) conducted in Hong Kong. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Objectives: To determine whether CRP-guided antibiotic treatment for managing AECOPD in adult patients attending Emergency Departments leads to reduced antibiotic duration, without non-inferior COPD health status with usual care. Hypothesis to be tested: (i) The antibiotic duration in AECOPD patients will be significantly lower for CRP-guided antibiotic discontinuation than usual care; and (ii) COPD health status as measured by the Clinical COPD Questionnaire has no statistically significant difference between two groups. Design and subjects: Multi-center, single-blind, open-label, randomized, combined superiority (antibiotic duration) and non-inferiority (COPD health status) trial in 1,184 adult AECOPD patients presented to A&E. Instruments: Clinical COPD Questionnaire and EuroQol-5D Interventions: Both intervention and control groups follow usual care with GOLD strategy. The intervention group will be recommended to test for serum CRP daily. Antibiotic prescription is considered when CRP >5mg/dL. Once CRP has declined to <5mg/dL and the patient was afebrile for past 48 hours, antibiotic discontinuation will be considered. Communication with Receiving Ward Staffs: Participants in the study may transfer to another departments after treatment/ care in A&E. The following communication would be conducted: - A handover note that informs the receiving ward staffs about patients' enrolment to the trial, group assignment, and previous treatments given in A&E. The note would also suggest the investigations for the receiving ward staffs. - Telephone handover about intervention group and investigations of the study, and treatments given in A&E to ward. Main outcome measures: The antibiotic duration (total number of antibiotic days) within 28 days and recovery in terms of COPD health status (Clinical COPD Questionnaire total scores) within 14 days from randomisation. Data analysis: Intention-to-treat and cost-effectiveness analyses will be performed. The outcome assessors and data analysts will be blinded to group allocation. Expected results: The intervention group will exhibit reduction in antibiotic duration at 4-weeks, without negatively impacting on COPD health status, compared with the control group.
This study will examine the effects of smartphone-based lifestyle medicine for alleviating generalised anxiety symptoms in Chinese population. Since a range of lifestyle factors are involved in the pathogenesis and progression of generalised anxiety disorder ( Cox & Olatunji, 2016; Dale et al., 2014; Vøllestad et al., 2012), modifying different lifestyle factors simultaneously, for examples, diet, exercise, stress and sleep, may be effective to reduce generalised anxiety symptoms. Recent studies indicate that service users are showing an increasing interest in self-help interventions for common mental disorders because of their accessibility and low cost (Marshall et al., 2021; Weisel et al., 2019). Nonetheless, to date, only limited self-help interventions that target lifestyle medicine for generalised anxiety symptoms are available. This study will be a randomised controlled trial on the effects of a self-help smartphone-based lifestyle medicine intervention for reducing generalised anxiety symptoms in Chinese population. Prior to all study procedures, eligible participants will be required to complete an online informed consent (with telephone support). Around 50 eligible participants will be randomly assigned to either smartphone-based lifestyle medicine (LM group) or the waitlist control group (WL group) in a ratio of 1:1. The randomization will be performed by an independent assessor using a computer-generated list of numbers. Participants in the LM group will receive the multicomponent lifestyle medicine intervention via the app for 8 weeks, whilst the WL control group will receive the intervention after trial completion. The primary outcomes will be the level of generalised anxiety symptoms at immediate and 3-month post-intervention assessments; while the secondary outcomes will be the level of depressive symptoms, insomnia symptoms, physical activity, health-related quality of life, functional impairment, health-promoting behaviours, and intervention acceptability at immediate and 3-month post-intervention assessments.
The study aims to evaluate the acceptability, feasibility, and preliminary efficacy of a digital lifestyle intervention, called Fitness Digital (FitD), for individuals with prediabetes or type 2 diabetes.
Cerebellar ataxia (CA) is a collection of signs and symptoms caused by cerebellar dysfunction, which can be the result of different disease processes including hereditary and acquired conditions. High incidence of falls is reported in people with CA due to poor balance while walking. Therefore, it is crucial to assess the balance of people with CA to identify potential fallers. There are some clinical tests commonly used for assessing the balance of people with CA, including both generic measures of balance and ataxia-specific rating scales. The current best balance outcome measures for CA includes Berg Balance Scale (BBS), Timed Up and Go test (TUG), and the balance related items in Scale for the assessment and rating of ataxia (SARA). TUG is commonly used in clinical settings for the assessment of mobility and fall risk of individuals. However, a study done by Winser et. al (2017) found that the correlation between TUG and ataxia rating scales (SARA and ICARS) is only moderate. This indicates that the gait speed and functional mobility findings of TUG might not truly reflect the balance deficits of CA. Therefore, our study will develop a modified TUG for the assessment of balance in people with CA. Circular TUG (cTUG) is a modified version of the standard TUG. cTUG is an equilibrium test that challenges subjects' ability to maintain balance in response to the constant change in direction of walking. In cTUG, the subject walks a semi-circular pathway instead of a straight line. Walking in a circular pathway targets at challenging the coordination of people with CA as walking in a circle requires constant change in directions and correction after feedback. It is speculated that the cTUG will have better accuracy in predicting the balance and falls risk among people with CA. We will target at recruiting 30 healthy volunteers and 30 individuals with cerebellar ataxia. Besides the cTUG we will also assess disease severity of ataxia using the Scale for the Assessment and Rating of Ataxia (SARA), balance using the Berg Balance Scale, Timed Up and Go test, Sensory Organization test, Limits of Stability test and functional independence using the Barthel Index. For validation of the cTUG, two types of reliability will be examined, including intra-rater reliability and interrater reliability and four types of validity will be assessed, including concurrent validity, convergent validity, discriminant validity, and external validity.
This is a two-arm, with equal randomization, parallel randomized controlled trial. It compares the efficacy of a couple-based Integrative Body-Mind-Spirit (I-BMS) group intervention to a waitlist control group in improving dyadic couple flourishing and fertility-related quality of life among couples who are diagnosed of infertility in Hong Kong. It also aims to investigate the dyadic associations between infertile husbands' and wives' baseline primary outcomes and changes in primary outcomes following the intervention.
This study aims to compare self-help lifestyle medicine (LM) delivered by a smartphone app and booklets in managing depressive symptoms in a Chinese population. This study is a randomised controlled trial. First, informed consent will be obtained from potential participants. Around 90 eligible participants will be randomly assigned to either the LM app group, the LM booklet group, and the waitlist control group, in a ratio of 1:1:1. The app group will receive an app to facilitate lifestyle modification such as video demonstrations of physical activity, diet recommendations, stress and sleep management. The booklet group will receive 8 LM booklets with identical content with the LM app. The waitlist control group will receive access to the app and booklets at the end of the study. The whole intervention lasts 8 weeks. Participants will also receive 2 messages per week from the researcher to check and prompt motivation and adherence. Participants will complete assessment before, immediately after intervention, at one month and 12-week follow up.
This study will examine the effect of Heart Rate Variability (HRV) biofeedback as adjunctive therapy to self-help Cognitive Behavioral Therapy on insomnia (CBT-I) in Chinese adult population. Heart Rate Variability Biofeedback is a therapy training aiming at increasing heart rate oscillations through real-time feedback and slow breathing training. Several literature has found that HRV biofeedback training is effective in improving HRV and improving sleep quality and sleep efficiency (Gevirtz, 2013; Lin et al., 2019). On the other hand, self-help CBT-I is well-studied in efficacy of improving cognition and behaviors and relieving insomnia (Ho et al., 2014). Rare research study HRV biofeedback as adjunctive therapy to self-help CBT-I (Lehrer, 2017). In the light of this, this study will compare the efficacy of combination of both treatments with that of CBT-I alone, examining whether HRV biofeedback's focus on psychophysiological domain can help self-help CBT-I in more significantly improving HRV and sleep quality.
It aims to compare the effects of a professional -led support programme using a mobile application versus telephone advice on clients at risk of coronary heart disease. A multi-centre, single-blinded, randomized controlled trial will be conducted. 168 Clients who are at risk of coronary heart disease (CHD), able to use a smart phone will be randomized into the App Support group (App group) or the Nursing Telephone advice (NTA) group . All participants will receive same nursing educational briefing related to CHD. The App Group will additional receive an app use to support their self care whereas the NTA group will receive nursing telephone advice for 20 minutes monthly. Health outcomes will be collected at baseline (T0), 1 months (T1), 3 months (T2). Data analysis will be conducted using a Generalized Estimating Equations model to assess differential changes in all outcome variables.
In this a 12-week, single blinded, randomized sham controlled, and cross-over clinical trial. It will be conducted to explore the safety and efficacy of acupuncture for olfactory dysfunction in infected COVID-19 patients in Hong Kong.
Radical perineal prostatectomy (RPP) was the first approach utilized for the removal of the entire prostate gland for prostate cancer. In the minimally invasive surgery era, the robotic-assisted laparoscopic prostatectomy (RALP) was first described in the early 2000s, and has become the mainstay of prostatectomy in Hong Kong and many parts of the world. Incorporating the robotic technology into the technique of RPP has been studied recently. Some preliminary data showed that such approach resulted in a better functional outcome in continence and erectile function. Our study aims at assessing the safety and effectiveness of robotic RPP in prostate cancer management.
