Chinese Singing Voice Handicap Index-10
Project Title:
Validation of the Singing Voice Handicap index-10 in Chinese in Singapore
Overview
Singers, both amateur and professional, may be susceptible to vocal impairment. As they are often more sensitive to their perceived voice problem, their quality of life might be more impacted compared to non-singers.
The Singing Voice Handicap Index-10 (SVHI-10) is a 10-item questionnaire to evaluate the impact of the singing voice on an individual's life (Cohen et al., 2009). It has to date not yet been validated in any other languages including Chinese which is one of the main languages used in Singapore. This study aims to validate the translated Chinese version of SVHI-10 in singers with and without voice disorders.

Expiratory Muscle Strength Training for Chronic Dysphagia
The effects of expiratory muscle strength training (EMST) on airway protection and swallowing in chronic dysphagia after radiation therapy
Radiation therapy for head and neck cancer (HNC) is associated with the development of swallowing difficulties, or dysphagia. Radiation-associated dysphagia can be intractable and not responsive to conventional dysphagia therapy. HNC survivors with chronic severe dysphagia may be dependent on long-term tube feeding.
Expiratory Muscle Strength Training (EMST) is a low-cost, device-driven therapy. It has been studied as an approach to simultaneously improve cough and swallowing functions. During EMST, patients forcefully expire into a one-way spring-loaded valve to strengthen expiratory and submental musculature. The EMST-150TM device is available for clinical use in Singapore. In research studies overseas, it has been shown to improve cough and swallowing in several populations of people with chronic dysphagia, most recently in people with chronic radiation-associated dysphagia.
This research examines the effect of EMST using the EMST-150TM device on cough, airway protection, and swallowing functions of HNC survivors with radiation-associated dysphagia. With the results of this study, we aim to develop better evidence-based rehabilitation programmes for HNC survivors, and those living with chronic dysphagia.

Thickening Oral Supplements
Thickening Supplements Accurately for Dysphagia Management
People with dysphagia (swallowing difficulty) may require their drinks, including liquid nutritional supplements, to be thickened up to reduce the risk of choking or aspiration. Liquid supplements are more difficult to thicken than plain water as they may become lumpy and too thick or watery over time. Healthcare staff and caregivers thus face the challenge of thickening supplements accurately and efficiently to ensure these are consumed safely.

Swallowing-Related Quality of Life in Head and Neck Cancer Survivors
Swallowing-related quality of life of head and neck cancer patients in Singapore: Validation of the MD Anderson Dysphagia Inventory
Swallowing difficulties, or dysphagia, is a common side effect of head and neck cancer (HNC) and related surgery and/or radiotherapy. It has a major impact on global quality of life (QOL). With advancements in organ preservation treatment and cancer surgery, head and neck cancer patients now live for longer, albeit with functional swallowing difficulties that can impact their lives significantly.
This study aims to validate the MD Anderson Dysphagia Inventory (MDADI) in English and translated Mandarin-Chinese versions in the Singapore HNC population. The MDADI is a 20-item self-administered questionnaire designed for HNC patients, and is validated across many languages. It is not yet validated in the Singapore population, or available in Mandarin-Chinese.
The resulting validated English and Mandarin-Chinese versions of the MDADI can then be an additional clinical tool from which to understand the implications of dysphagia on QOL in HNC patients in Singapore.

Perspective of Parents towards Speech and Langauge Development of Children in Singapore
Exploring the knowledge, attitudes and practices of local parents with respect to speech and language development.
In Singapore, more young children are diagnosed with developmental problems including speech and language delays. Earlier detection and intervention improve outcomes of these children. Parents' involvement has also been shown to result in better speech and language outcomes in children. Parents' knowledge, attitudes and practices will therefore contribute to the extent and quality of support children will receive.
The aim of this study is to explore the knowledge, attitudes and practices of local parents with children between ages 1 to 5, with regards to the speech and language development of children.
The study is conducted through focus groups and interviews. Parents of young children (between ages 1 to 5) are recruited.
A better understanding of parents' knowledge, attitudes and practices can potentially help service providers and policy makers to improve service delivery, to remove barriers hindering parents' involvement in and support of their child's speech and language development. This is also in line with national efforts to identify these children earlier, and to provide earlier and better support to them.

Functional Outcomes in Nasopharyngeal Cancer Survivors
A prospective pilot study of functional outcomes of patients with nasopharyngeal carcinoma after radiotherapy
This is a prospective, cohort study collecting epidemiology data, treatment data, longitudinal side effects, saliva samples and quality of life data (before and to 1 year after radiotherapy) in patients with nasopharyngeal cancer. Standardised data collection incorporates objective measurements of functional outcomes (eg. swallowing, hearing and salivary function). The aim of this pilot study is to develop, validate, and improve prediction models for survival and also reduce acute and late radiation induced side effects relevant to patients with nasopharyngeal cancer.
This study is supported by an SGH Research Grant FY2017 awarded to Ms Jamie Loy.

Clinical Outcomes of a Multidisciplinary Tracheostomy Review Team
Predictors of clinical outcome after tracheostomy post implementation of multidisciplinary tracheostomy review team
The creation of tracheostomies allows earlier discharge of patients from the Intensive Care Unit (ICU), shifting the management of tracheostomy patients from the ICU team to the primary managing team. The continued care of patients with tracheostomies requires a degree of specialist knowledge, for example, on tube care, wound care, secretion management, and planning for decannulation.
The primary goal of this study is to describe the demographics of patients requiring tracheostomy tube placement in SGH, as well as to identify factors associated with outcomes in these patients. Secondary goals include: The evaluation of outcomes for patients who are managed by the tracheostomy team versus other tracheostomy patients of similar etiologies, comparing local outcomes with internationally published data, and evaluating the effectiveness of a physician-led team in comparison with the team comprising only allied health professionals.

Oral Health Assessment Tool used by Speech Therapists
Project Title: Validity and reliability of the Oral Health Assessment Tool (OHAT) as used by
speech therapists
Patients with swallowing impairment (dysphagia) may be susceptible to aspiration pneumonia due to chronic aspiration of food and fluids. Aspiration pneumonia risk increases when dysphagia occurs in combination with poor oral hygiene, poor functional status, and multiple comorbidities. To minimize complications associated with sub-optimal oral health, oral health screening is necessary to identify patients who require further intervention.
The Oral Health Assessment Tool (OHAT) has been developed for use by non-dental professionals such as nurses, caregivers, allied health and medical professionals. Preliminary research suggest that speech therapists (STs) can administer the OHAT with satisfactory inter-rater, intra-rater and test-retest reliability after a 3-hour training session (Simpelaere et al., 2016). However, agreement of OHAT scores among STs does not imply accuracy in using the tool. The accuracy of STs' ratings on the OHAT compared to administration of the same tool by a qualified dental professional has not been established.
This study will investigate the effect of training on the accuracy and reliability of STs in administering the OHAT compared to the dental hygienist.
