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.
This study evaluates the feasibility and the preliminary effects of a simplified 10-step Tai-chi programme (a dyadic approach) on the mobility performance of people with mild to moderate dementia. Four community health centres were recruited and each was randomised to either the intervention group (Tai-chi) or the control group. Tai-chi group received a 16-week 10-step simplified Tai-chi training programme in which additional measures were implemented to enhance participants' engagement. The control group took part in group recreational activities organized by the community centres. It was hypothesized that the Tai-chi group would outperform the control group regarding their mobility performance.
Investigate the optimal timing for weight bearing after Hallux Valgus surgery. Hypothesis: Early weight bearing does not affect outcome after the Endoscopic Distal Soft Tissue Procedure for Hallux Valgus Correction.
Diabetes mellitus (DM) and hypertension (HT) are major causes of morbidity and among the top 10 causes of deaths in Hong Kong in 2008 (Department of Health 2009). The Hospital Authority (HA) has initiated service improvement through introducing the shared-care (SC) programme to improve the quality of care (QOC) for DM and HT patients. The evaluation on the QOC is an essential part of the programme in order to inform future policy. The Family Medicine Unit (FMU) of the University of Hong Kong (HKU) has been appointed by the HA to carry out the evaluation of the QOC of the programme. The Action Learning and Audit Spiral methodologies to measure whether the target standard of care intended by the SC programme is achieved. Each SC participating clinic and private medical practitioner (PMP) will be invited to complete a structured evaluation questionnaire. The data of all patients who have enrolled into the programme will be included in the evaluation on the process and outcomes of care. A hundred and thirty participants will be followed up by telephone to evaluate the effect of the programme in quality of life (QOL), patient enablement, and global rating of change in health condition at baseline and 6 months after enrolment. Data on the process of care will be retrieved from the HA medical records. Main Outcome Measures: The primary outcomes are the proportion of participants who received the criterion process of care and achieved a HbA1c level <7.5%. Data Analysis: Descriptive statistics on proportions of clinics or subjects meeting the quality of care criteria will be calculated. The outcomes of SC patients will be compared at 6, 12, 24, 36 and 48 months by paired sample t-test. The outcomes between SC patients and control group will be compared by independent sample t-test or Chi-square test. Hypothesis: The QOC of the SC programme will be determined. Areas of deficiency and possible areas for quality enhancement will be identified. The results of this study will provide empirical evidence on whether the HA's SC programme can achieve equivalent QOC as the usual HA care for diabetes mellitus (DM) patients. The information will be used to guide service planning and policy decision making.
Aims: To enhance mental well-being of adults by creating a positive, happy and joyful environment in the community. Targets: Adults aged 18-59 in Hong Kong. Methods: SME Ambassadors Pilot Project will adopt the public health and family-focused approach, under the brand name of "Joyful@HK Campaign". Evidence-based and Evidence Generating approach with vigorous study design, both qualitative (e.g. focus groups) and quantitative (e.g. pre- and post- test), will be used to evaluate the overall programme effectiveness including follow-up of at least one month ("best science"). To ensure the practicability and sustainability of the community-based engagement project, we will engage community partners with strong track records of "best practice" to design, plan, and implement the intervention. This project will use innovative and integrated positive psychology and public health theories and methods to plan brief, simple, and cost-effective intervention. Significance: By using "best science" in the design and evaluation of intervention programme, and the "best practice" of the partners' skills, experience and strong connection with service targets in the community, the intervention, if proven to be effective, for promoting sharing, mind and enjoyment and enhancing mental well-being can be further developed and widely disseminated to and adopted by the practitioners in the health and social service sectors for replication and improvement to benefit the whole population.
Aims: To enhance mental well-being of adolescents, adults and their families by creating a positive, happy and joyful environment in the community. Targets: Adults aged 18-59 and their family members in Hong Kong. Methods: Healthy Community Pilot Project will adopt the public health and family-focused approach, under the brand name of "Joyful@HK Campaign". Evidence-based and Evidence Generating approach with vigorous study design, both qualitative (e.g. focus groups) and quantitative (e.g. randomised controlled trial), will be used to evaluate the overall programme effectiveness including follow-up of at least one month ("best science").

High Intensity Focused Ultrasound (HIFU) is a new approach in treating benign thyroid nodule without surgery. It is proven effective and safe relative to traditional surgery. From previous HIFU studies, it caused shrinkage of thyroid nodule up to 70% from original size. Unfortunately, 5-10% of nodule do not shrink. Those which do not shrink are usually large in size and therefore a second HIFU treatment may help. This study is going to evaluate the efficacy and safety of reapplication HIFU after the first single HIFU session in 6 months. The study will be carried out in the following steps: 1. Recruit subject from the clinic according to the study criteria. 2. Arrange the reapplication HIFU treatment within 3 months. 3. Arrange 4 visits after the HIFU treatment in Post 7 days, Post 1 month, Post 3 months, and Post 6 months; Data collection will be in these 4 visits through the questionnaire or interview by research assistant 4. The subjects will have further health management with the same team after the study.
Endometrial cancer is the most common malignancy of the female genital tract in Hong Kong. The aim in the evaluation of PMB is to exclude underlying malignancy. Endometrial thickness (ET) measured by transvaginal ultrasound scanning (TVS) and endometrial biopsy or sampling (ES) has been recommended as the first-line investigation. From a study between 2002-2013 in the One-stop PMB clinic, investigators found that ET was able to identify women with endometrial cancer with the sensitivity at 3mm, 4mm, and 5mm, the current levels recommended in professional guidelines, being 97.0%, 94.1%, and 93.5% respectively. However, little is known about the level of patient's acceptance of the false negative rate and how patient would trade residual risk with more invasive test. There is also a lack of study on the experience of women during the management pathway especially the level of anxiety before and after investigations and the pain experienced from the investigations offered. The current study aim to study the level of false negative rate accepted by women for the investigation of PMB and the level of anxiety and pain experienced during the investigation pathway.
The aim of the study is to assess the health-related quality of life (HRQOL) and preference-based health utilities of chronic hepatitis B (CHB) carriers in different stages of illness. It will also estimate the cost-effectiveness of anti-viral treatments resulting from the prevention of the progression of disease from uncomplicated CHB carriers to cirrhosis and hepatocellular carcinoma (HCC). The following hypotheses will be tested: 1. Patients with chronic hepatitis B virus (HBV) have poorer health-related quality of life (HRQOL) than the general population; 2. Patients with more severe stages of chronic HB infections have lower health related quality of life and health utility values; 3. Anti-viral treatment can improve the HRQOL and health utility for patients with CHB infections; 4. The cost-effectiveness of different treatments for chronic HBV infections can be directly compared in terms of cost/QALY gained.
This is a non-blinded, randomized controlled trial for testing two brace weaning protocols namely immediate removal of brace or gradual weaning of brace over a course of 6 months for adolescent idiopathic scoliosis (AIS) patients. These patients will have follow-up visits at 6-months, 12-months and 24-months intervals. By comparing between the two groups in terms of change of Cobb angle, truncal balance, health-related quality of life measures at the set time-points, the investigators aim to gain insights of whether different brace-weaning protocol will be more beneficial in patients' clinical and quality of life measure outcomes.
