Self-Care for Older People With Diabetes Mellitus

Overview This study is a prospective, four-group cluster randomized controlled trial. The participants will be followed up for 6 months at the community sites or Hua Mei Clinics of the Tsao Foundation. The 4 groups are: i. Control group receiving routine care from their healthcare provider/ clinics of Tsao Foundation ii. Intervention group 1 receiving the SCOPE-DM programme without supply of glucometers and accessories iii. Intervention group 2 receiving the SCOPE-DM programme as well as 3 months' supply of glucometers and accessories iv. Intervention group 3 receiving the SCOPE-DM programme as well as 6 months' supply of glucometers and accessories A staff of Tsao Foundation will recruit community-dwelling adults with diabetes from the 68 community sites around Singapore. After which, the research associate (RA) or Fellow appointed to represent the Site Principal Investigator will screen the individuals participating for eligibility to join this research study. Alternatively, potential participants will be referred to the RA or Fellow to be screened for eligibility. Eligible individuals will be invited to participate in the research study, of which interested individuals will be explained with the study procedure and informed consent will be taken by the RA. Inclusion Criteria: * Individuals with type 2 diabetes mellitus * Aged 55 to 99 years old (both inclusive) * Community-dwelling Exclusion Criteria: * Individuals with Type 1 diabetes mellitus * Unable to communicate independently in English or Mandarin * Mentally incapacitated individuals The 68 sites will form the cluster sites for the study and will be assigned to any one of the 4 groups via a randomisation process (control, intervention group 1, 2 and 3). The randomisation process will be generated by the research team before recruitment begins using a computerised programme. Each group will thus consist of 17 sites. All the participants belonging to each group of 17 sites will be invited to participate in the study if they meet the inclusion criteria until we have reached the target number of 80 for each group. Questionnaire administration Questionnaires to elucidate the humanistic outcomes will be administered at baseline, 3 and 6 months from baseline respectively for all 4 groups. Each questionnaire administration will last for around 45 minutes. The questionnaire will be used to assess participants' self-efficacy, diabetic self-care activities, health-related quality of life (HRQoL), diabetes knowledge and medication adherence. Participant demographics, anthropometric parameters, past medical history, and current medication use will be collected. A staff from Tsao Foundation will provide the clinical data and laboratory test results (HbA1c, blood pressure, TChol, LDL-C, HDL-C, TG, BMI and adherence to yearly eye and foot screenings) to the RA or Fellow of the project. Consent will be obtained from the participants before Tsao Foundation releases the clinical data and laboratory test results to the research team. The data and test results will be printed out by the staff of Tsao Foundation and handed over to the RA or Fellow in an opaque sealed envelope. Only the RA or Fellow, Co-Investigators and Principal Investigators of the study are authorised to open the sealed envelope and retrieve data. A representative of Tsao Foundation may call the subject for care- and administrative-related matters if needed such as reminding the participants to attend the SCOPE-DM programme or to follow up on the questionnaire administration. Process Evaluation The purpose of the process evaluation is to assess the acceptability, strengths and weaknesses of the 'SCOPE-DM: Live Well with Diabetes' programme based on the participants' perspectives. A qualitative approach using individual face-to-face audio-recorded interviews will be adopted. The RA will conduct these interviews after the completion of the study intervention and upon the participant's consent. A purposive sample of 30 participants will be recruited from intervention groups to participate in the interviews to share their experiences while in the programme as well as obtain their opinions and suggestions to improve the programme. All interviews will be audio-recorded. An interview guide will be developed based on the overall aim of the SCOPE-DM program. The participants will be reminded not to reveal any information that may identify themselves before the interview commences as interviews will be audio-recorded. The qualitative interview will last for about 1 hour. The administration of the questionnaires and conduct of the interviews will be done at a room with privacy and confidentiality maintained at the Hua Mei Clinics or any of the community sites. The venue to administer the questionnaires and interviews are appropriately equipped with tables, chairs and rooms to ensure the privacy and confidentiality of participants. Details of SCOPE-DM intervention programme Tsao Foundation's trained diabetes nurse educators will commence the SCOPE-DM intervention programme once 8 to 10 participants agreed to participate. Tsao Foundation will be responsible for training 20 diabetes nurse educators to deliver the programme. The SCOPE-DM programme will be conducted at Hua Mei Clinics or any of the community sites. Each session will last around 2 hours. The programme aims to support motivation and enable capability for managing diabetes. To this end, the session will integrate the knowledge and practical skills components offered in traditional diabetes education with psychological techniques and principles for behavioural change: problem solving, goal-setting and monitoring. The programme offers the potential for older people to learn about their condition and treatment in a psychologically-motivating and confidence-enhancing structure - as such the emphasis is on empowering individuals to make choices and lifestyle changes in line with treatment recommendations through the use of problem solving, goal setting and feedback, and not just on knowledge transfer which has not been shown to be successful in behavioural change. The content and delivery format will largely be informed by motivational interviewing (MI). Motivational interviewing is a well-recognized person-centered counselling approach aiming at eliciting and strengthening motivation to change. It is designed to guide towards a specific goal by eliciting and exploring the person's own reasons for change, goals and values within an atmosphere of acceptance and empathy.There is now a wealth of evidence from randomized trials for the effectiveness of MI in health behavioural change.To facilitate engagement and rapport with the participants, MI will be blended with guided autobiography as means to share life experiences and meaning and hence allowing for better alignment of health behavioural changes with participants' personal goals and values. The 2-hour weekly sessions will apply the strategies of group-based activities, problem solving, motivational building and goal setting, vicarious experience, enactive attainment and physiological feedback. Themes will include dealing with the medical management of the disease (medical management); maintaining, changing, and creating new meaningful behaviours or life roles (role management), and dealing with the emotional consequences of having a chronic condition (emotional management). These topics are taught by means of skills mastery through goal setting and feedback on progress, modelling of self-management behaviours and problem-solving strategies, and social persuasion through group support and guidance for individual self-management efforts.
