Feasibility of a Home Hazard Management Program for Malaysian Stroke Survivors

Study Overview
=================
Brief Summary
-----------------
This quasi experimental design study aims to examine the feasibility and potential effectiveness of a home hazard management program to reduce the rate of falls and fear of falling among Malaysian community dwelling stroke survivors. This study will be conducted in three local government hospitals in central Malaysia.

Detailed Description
-----------------
This study is a pilot quasi experimental study which consists of two groups namely the intervention and control group. The experimental group will be implementing the suggested home modifications as well as education for functional performance in the homes. In addition, this study is a pilot study, therefore the feasibility of the intervention to be implemented in practice will be investigated. Other than that, this study also focuses on the outcomes from the results in which to analyse the effect of home assessment and modifications on rate of falls and fear of falling. The study location is at Hospital Selayang, Hospital UPM and Hospital Shah Alam. However, the intervention will be conducted at selected participants homes. Convenient sampling will be conducted as the sampling method for this study. Any participants that fulfil the inclusion criteria will be approach for participation. Information of potential participants will be retrieved from the appointment book or online appointment system as well as their medical records. The screening and recruitment of participants will occur on the same day as their appointment at the hospital by a co-investigator at site. Prior to participating, all participants are required to fill up a written consent form. The co-investigator at site will approach the participants and explain in detail about the study. Information regarding the study, the risk and benefits, confidentiality, withdrawal from the study and questionnaires will also be conveyed. Participants will also be informed that they will not be paid for their participation, but they will receive a certificate of appreciation. Potential participants will be allowed sufficient time to consider their participation in the study. Consented participants will be screened using the Modified Rankin Scale and the 6-item Cognitive Impairment Test and be invited to take part in the study. The participants will be conveniently located into two different groups, namely the intervention group and the control group. All participants will be given an appointment for an online telehealth session according to the participants appropriate time. The telehealth platform that will be used for this study is Coviu-an integrated and specialized telehealth platform which is HIPAA-compliant (https://www.coviu.com/). A falls diary will also be given to participants by email or mail to record any falls they encountered within 3 months after the initial assessment. The participants will then be re-assessed after the 3 months from the initial baseline assessments. During the 3 months follow up, the participants are re-assessed using the same initial baseline questionnaires. The falls dairy will also be collected via email for analysis. Recruitment of participants during the initial baseline assessment will stop once it has reached 30 participants. However, withdrawal participants will be replaced, until the required sample size is achieved. Hospital Selayang and Hospital Pengajar UPM is conveniently chosen as the hospital for the intervention group while Hospital Shah Alam is chosen for the control group. These hospitals are chosen because of its accessibility for the researchers.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from home hazards baseline at 3 months | HOMEFAST is a 25-item form that evaluates the performance of individuals to perform activities safely in the home environment. It assesses seven aspects of use i.e. floors, furniture arrangements, lighting, bathrooms, kitchen storage, staircases and movements (Mackenzie, Byles & Higginbotham, 2000). It has scientific evidence in terms of validity and reliability. It has been tested for senior citizens living in the community and can be used by senior citizens, or health professionals (e.g., job-rearing practitioners, social workers, nurses, health science practitioners and medical practitioners) and the public (Romli et al, 2018; Romli et al., 2017). The scores are 0 for Yes and 1 for No. All the scores will be added up to form 1 total score. The total score is 25. A higher score indicates a higher risk of falling. The assessment will be administered twice during the study trial. | Initial baseline assessment and within 1 week after the 3 months intervention | 
| Change from falls efficacy baseline at 3 months | The FES-I short form is a 7-item questionnaire of fall-related self-efficacy based on the Falls Efficacy Scale-International (16 items) (Kempen et al., 2008). It has a 4-Likert scale from 1 'not at all concerned' to 4 'very concerned'. Higher values indicate less fall-related self-efficacy (and more concern about falling). The internal and 4-week test- retest reliability of the Short FES-I is excellent (Cronbach's alpha 0.92, intra-class coefficient 0.83) and comparable to the FES-I. The correlation between the Short FES-I and the FES-I is 0.97 (Kempen et al., 2008). The FES-I short form has been translated in Malay and Mandarin and has good reliability and validity (Tan et al., 2018). The assessment will be administered twice during the study trial. | Initial baseline assessment and within 1 week after the 3 months intervention | 
| Falls Diary | The falls diary is the preferred method of falls monitoring (Lord, Sherrington, Menz, & Close, 2007) as it enables falls to be recorded immediately after they have occurred, minimizing the chance of participants forgetting to report a fall. The falls diary includes a calendar for each month of the study (3 months). Participants will have to tick at each box of every day whether they have fallen or not. If they fall on a specific day, the is another page which the participants must detail out the date, activity, time during the fall and if they when to see the doctor after the fall. | 3 months within the intervention duration | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from stroke recovery baseline at 3 months | Stroke Impact Scale is a 59-item measure that covers 8 domains namely strength, hand function, ADL/IADL, mobility, communication, emotion, memory and thinking and participation (Duncan et al., 1999). Each item is rated in a 5- Likert scale in terms of the difficulty the patient has experienced in completing each item. Scores range from 0 to 100, a higher score indicates better recovery. The SIS has adequate to excellent test-rest reliability (Duncan et al., 1999) and excellent criterion validity (Duncan et al., 2002). The assessment will be administered twice during the study trial. | Initial baseline assessment and 1 week after the 3 months intervention | 
| Change from quality of life baseline at 3 months | The SF-12 is a multipurpose measure of QOL derived from the SF-36 (Ware, Kosinski & Keller, 1996). Two summary measures are produced, the physical component summary (PCS) and mental component summary (MCS) (Turner-Bowker et al., 2003). The 12 items in the SF-12 includes 1 or 2 items from each of the 8 health concepts: physical functioning, role limitations because of physical health problems, bodily pain, general health, vitality (energy/fatigue), social functioning, role limitations because of emotional problems, and mental health (psychological distress and psychological well-being)(Ellis et al., 2013). Finally, because the 8 domains have different ranges, they are transformed to have a common range of 0 (worst health) to 100 (best health). | Initial baseline assessment and 1 week after the 3 months intervention | 
| Change from caregiver's burden recovery baseline at 3 months | The Zarit Burden Interview (ZBI) 22-item questionnaire developed by Zarit et al. (1985) has been used extensively in measuring caregiving strain. In addition, shorter versions of the ZBI ranging from 1 to 18 items, have been developed. However, Yu et al. (2019) found that the 6-item version was the most optimal short version as it provided similar diagnostic utility to the original 22-item version with the fewest items. The self-report instrument measures two dimension of caregiving namely personal and role strain using a 5-point scale ranging from 0 'never' to 4 'nearly always' (Herbert, Bravo and Preville, 2000). The scores of each item are added up to form one total score. The maximum score is 88 and higher scores indicate greater burden. | Initial baseline assessment and 1 week after the 3 months intervention | 
| Change from occupational performance baseline at 3 months | The Canadian Occupational Performance Measure (COPM) based on the Canadian Model of Occupational Performance is designed for use by occupational therapists to detect change in patients' self-perception of their occupational performance over time (Law et al., 1998). With a semi-structured interview, the patient is encouraged to identify problems in self-care, productivity, or leisure activities. It concerns those activities the patient wants, needs, or is expected to do, but cannot do, or those in which the patient is not satisfied with current performance. The patient rates importance of the problems on a 10-point scale from 'not important at all' (score 1) to 'extremely important' (score 10). The patient is also asked to rate satisfaction with performance on a 10-point scale from 'not satisfied at all' to 'extremely satisfied'. These scores range from 0 to 10, higher scores reflect better performance and satisfaction with performance as perceived by the patient. | Initial baseline assessment and 1 week after the 3 months intervention |
