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 aims to conduct a randomized controlled trial in comparing cognitive behavioral insomnia prevention program with the active control group in youths who are at risk of insomnia. The results of this study will allow us to take this potential efficacious prevention program to scale and reduce the associated burden of insomnia in the future.
The aim of this study is to strengthen the evidence base of clients' preferences of psychotherapy and to close the described literature gaps so as to inform public health resource reallocation and implementation of psychological services. The investigators aim to address the following research questions: 1. Which psychological service attributes exert the most influence on the service use decisions? 2. Can respondents be represented by latent classes on the basis of similar preference profiles? 3. Which attributes exert the most influence on the service utilization decisions of each latent class? 4. Will people with depression adopt Internet-based psychotherapy considering the long waiting time and high cost of conventional face-to-face psychotherapy? To systematically address the above questions, specific research objectives are defined as follows: 1. to examine the relative importance of a series of characteristics of psychological services (e.g., delivery modality, waiting time, out-of-pocket service fee, anonymity and referral methods) on the choices of psychological service using DCE. 2. to identify segments of people with depression with different service preferences using latent class model, because the relative weighting of service preferences may vary with demographic (e.g., gender, age, socioeconomic status, depression severity) and psychological characteristics (e.g., help seeking stigma); and 3. since DCEs need to be translated into improved services to be truly useful, and with reference to emerging interest in the development of digital mental health service for people with depression to solve the issue of long waiting time and cost in face-to-face psychotherapy, using a series of statistical simulations, we aim to estimate the percentage of people with depression in each latent class segment who would use psychotherapy with pre-defined treatment attributes packages.
The aim of this study is to investigate the effectiveness of the family and behavioral theory based mobile-health behavioral intervention in enhancing adolescents'good oral health behaviors (mainly oral hygiene practice and free sugar intake control) and preventing common oral diseases (dental caries and periodontal diseases).
This is a pilot study on applying 3D-Ultrasound-Guided Transperineal Microwave needle ablation for men with symptomatic benign prostatic hyperplasia (BPH).
This is a prospective clinical study recruiting 510 men at risk of PCa to undergo urine, blood, AI-assisted ultrasound and AI-assisted MRI investigations to stratify risk of clinically significant PCa (csPCa). (sample size calculation in section 5)
Health care costs are increasing alarmingly, which will impose an overwhelming economic burden to an aging society like that of Hong Kong. For example, degenerative musculoskeletal disorders such as osteoarthritis (OA) present a grand challenge with its high prevalence (>40% in the elderly suffered from knee OA). Knee osteoarthritis (OA) is the most common form of arthritis, and around 2 million population worldwide suffer from this disorder. OA is a debilitating progressive disease with typical pathological progress such as cartilage degeneration, inflammation, joint width narrowing and developing osteophytes. The main system of knee OA is acute pain leading to loss of mobility. There is no effective treatment to cure or stop the progression of OA. For now, the main method is to alleviate the pain and symptoms, including control weight, exercise, physical treatment and intake of NSAIDs/ paracetamol. Pulsed electromagnetic field (PEMF) treatment has shown to enhance cell activity related to tissue healing, delay bone and cartilage degeneration and give beneficial effects such as relief in pain, anti-inflammation and reduce swelling. In clinic, PEMF treatment has been reported to be safe, and has been proved to reduce the usage of NSAIDs and pain in patients with knee OA. This study aims to investigate the effectiveness of PEMF therapy on for patients with knee OA, including delay the degeneration of articular cartilage, restore the subchondral bone, reduce knee pain and symptoms as well as improve the muscle strength and functions, and even improving the quality of life. Based on the aim of this study, older adult patients (aged 50 or above) with a unilateral knee OA with Kellgren-Lawrence (KL) grade 2-3 by X-ray, visual analogue scale (VAS) >4, no acute knee injuries and muscle strain in past 3 months, and no alleviation of symptoms after ≥ 3 months of nonsurgical treatment. To estimate the improvement of patients the following assessments will be performed, including patient-reported outcomes, muscle strength and physical function assessments, serum evaluation, and imaging examination.
This is a prospective series of consecutive cases of patients undergoing iTind for the treatment of male LUTS.
There are many controversies and limitations in the management of Upper Tract Urothelial cancer. A prospective registry is set up for patients in our hospital, aim to have a comprehensive prospective assessment of the physical and biological effects of Upper Tract Urothelial cancer in our patients
This study is to investigate, in a larger cohort of consecutive men, the proportion of abnormal MRI prostate in different phi ranges, and the cancer detected in Chinese men with abnormal MRI. This study aims to evaluate whether MRI prostate can be omitted in men with lower suspicion of prostate cancer.
Obstetric anal sphincter injury (OASIS) is a serious complication of a vaginal delivery. High proportion of women, 40-59%, suffer from faecal incontinence (FI) after this type of injury.1-3 OASIS and FI have a negative impact on women's quality of life.4 The rate of elective caesarean section at second birth was much higher in women with OASIS at first birth compared with women without the injury (adjusted odds ratio 18.3, 95% CI 16.4-20.4).5 Primiparity has an increased risk of OASIS (odds ratio (OR) 2.39-8.34).6,7 Other factors are macrosomia and instrumental vaginal delivery.6,7 The role of episiotomy on OASIS has also been widely studied but there are controversial results. There were around 500-7000 deliveries at Prince of Wales Hospital annually. Among them, 50-55% was nulliparous women. About 65 -70% of women had normal vaginal delivery and another 5-10% had instrumental delivery. There was a change from 'routine episiotomy' to a more restrictive use of episiotomy in normal vaginal delivery during the last 10 years, with a reduction of rate of episiotomy from 90% to about 50% (from Dept.'s internal audit). The objective of this study is to evaluate the prevalence of OASIS in the era of a reduction of episiotomy.
