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.
A prospective study to examine the fall characteristics among elderly faller in Hong Kong and the potential predictors of falls incidence.
A randomized controlled trial to evaluate the effectiveness of smoking reduction interventions for smoking parents in paediatric hospital setting in Hong Kong.
Many of the existing mobile health (mHealth) apps designed in a reactive care approach, in which people do not receive individualized care until they consulted health care professionals through the apps. This proposal endeavors to develop a proactive mHealth application on promoting self-care ability and health among older adults to examine the differential benefits of adding nurse interaction supported by an integrated health-social partnership model in the use of mHealth.
Propofol used as anaesthesia in surgery had shown small postoperative analgesic benefits over inhalational anaesthetics in some meta-analyses. It was also associated with reduced risk of postoperative nausea and vomiting. Small sample of studies together with high heterogeneity prevented some meta-analyses to confirm propofol's effect for postoperative morphine consumption and other outcomes. Acute Pain Service data bank can provide an alternative way of evaluating postoperative outcomes of propofol anaesthetics through supplying a very large sample size in a more homogeneous setting. Retrospective study comparing propofol and inhalational anaesthetics on postoperative pain matched on patients' demographic and clinical data had been done for liver surgery. Propofol's benefits for postoperative pain and morphine consumption was confirmed but not for adverse effects. This study plans to analyze the postoperative outcome data from an Acute Pain Service data bank in years 2015-17 to compare the anaesthetics of propofol and inhalational anaesthetics. Comprehensive regression adjustment for confounders are performed using all available patients' demographic, clinical and anaesthetic data. All major surgery types are included. Results will provide postoperative outcome differences between propofol and inhalational anaesthetics for all surgeries and for specific type of surgeries. The large sample bank will provide higher probability for detecting outcome difference between the anaesthetics for all the major surgical types.
Transcranial direct current stimulation (tDCS) had recently been shown having feasibility in modulating cortical excitability transiently during motor training in a noninvasive way. The findings support that tDCS and motor practice can positively promote post-stroke motor learning to improve upper-limb motor recovery after stroke. A randomized controlled trial will be conducted with three groups: HD-tDCS, conventional tDCS and sham HD-tDCS. A 10-session training will be provided to evaluate the effectiveness of transient modulation of cortical excitability through tDCS with clinical assessment scores.
With effective anti-retroviral therapy, non-communicable diseases, such as cardiovascular diseases, have become the major cause of morbidity and mortality for people living with HIV. There is only limited data evaluating the burden and risk factors of cardiovascular disease in the Asian HIV-infected population. Accurate non-invasive tools for prediction of cardiovascular disease, particularly in Asian HIV-infected populations, are urgently needed. Recently, more detailed evaluation of the complex retinal vasculature has been made feasible with advances in digitalized retinal imaging techniques. This study aims 1. to determine the prevalence of coronary atherosclerosis and obstructive coronary artery disease HIV-infected individuals with one or more cardiovascular disease risk factors in Asia. 2. to determine the performance of automatic retinal image analysis (ARIA) in predicting the risk of coronary artery disease in HIV-infected individuals, as compared to traditional risk prediction tools. Patients will undergo a coronary CT angiogram, followed by an automatic retinal image analysis within 4 weeks post completion of CT angiogram.
Smoking causes cardiovascular and respiratory diseases, cancers and diabetes, and it has been a leading risk factor for death globally. Despite the availability of smoking cessation services locally, most smokers do not use such services. Workplace is one of the most convenient platforms to provide smoking cessation services and over 55% of smokers are employed according to the local population-based survey. However, the effectiveness of a smoking cessation programme conducted in workplace is yet to be examined in Hong Kong, and the attitudes and practices of corporations in promoting smoking cessation are not clear. Thus, this study aims to examine the employers'/ managerial staff's knowledge, attitudes and practices in promoting smoking cessation in workplace and evaluate the smoking behaviors of participants before and after attending a smoking cessation intervention.
This study aims to examine the efficacy of using Information Communication Technology (ICT) to deliver brief Motivational Interviewing (BMI) to promote regular physical activity among Hong Kong Chinese childhood cancer survivors.
Cancer is one of the major causes of death in pediatric population. In Hong Kong, childhood cancer remains a significant concern in healthcare system because of its damaging impacts on adolescent's physical and psychological functions throughout their lifespan. Particularly, adolescents surviving cancer still have to bear the health burden of numerous sequelae, even their treatment is completed for months and even years. One of the most prevalent symptoms reported by patients surviving cancer is sleep disturbance. The causes of sleep disturbance are multifactorial. However, it can largely be attributed to disruption of circadian rhythm by prolonged use of medications and long-term hospitalization. Experiencing sleep disturbance can be devastating for survivors of cancer and precipitates inflammation and oxidative stress, which are known to be a contributing factor of neurocognitive impairment. Sleep disturbance can also lead to fatigue, which in turn limits patients' capacity in engaging in daily activities and even results in depression, severely compromising patients' quality of life in the long run. Having a reliable and valid instrument that can precisely assess the problem of sleep disturbance of cancer survivors is therefore crucial for the development and evaluation of the intervention. The Pittsburgh Sleep Quality Index (PSQI) is the most commonly and frequently used instrument to assess sleep disturbance. Because of differences in culture and language, some concepts or items in the English version may be inappropriate for adolescents living in Hong Kong. Moreover, the psychometrics of the PSQI has only been established in adolescents undergoing active treatment for cancer, when they experienced the most severe problem. It is therefore unclear whether the PSQI can also be used to assess sleep disturbance of adolescents who have completed cancer treatment. This lack of validated instruments precludes us from understanding the severity of the problem. Also, it hinders the development of appropriate interventions that promote sleep quality. This study aims to bridge the gap in existing literature by translating the PSQI from English into Chinese, and examining the psychometrics of the translated PSQI in Hong Kong Chinese childhood cancer survivors.
This is a 8-week pilot randomized controlled trial utilizing bibliotherapy compared with usual care to investigate the feasibility and acceptability of bibliotherapy among informal caregivers of people with dementia in China, and preliminarily examine the efficacy on improving caregiving appraisal.
