Optimizing Care of Patients Via Telehealth In Monitoring and Augmenting Their Control of Diabetes Mellitus

Study Overview
=================
Brief Summary
-----------------
OPTIMUM study aims to use the telehealth-enabled chronic disease management programme for individuals with chronic diseases to provide timely intervention to prevent disease deterioration, increase compliance to treatment regimen (e.g. medication), and most importantly, engage participants to better manage their own care.

Detailed Description
-----------------
Over 400,000 Singaporeans are living with diabetes, with PM Lee Hsien Loong calling it a health crisis and the Ministry of Health declaring a War on Diabetes in 2016. One in three Singaporeans has a lifetime risk of getting diabetes and the number of those with diabetes is projected to reach one million by 2050, if current trends continue. Life years lost due to mortality and ill-health related to diabetes was the 4th largest among all diseases in 2010 while the cost burden from diabetes, including medical expenses and productivity loss, was expected to rise from beyond $940 million in 2014 to $1.8 billion in 2050. In addition, every year in Singapore, 2 in 3 new kidney failure cases are due to diabetes, and 1 in 2 people who suffer from a heart attack had co-existing diabetes. Tele-health projects have been conducted successfully overseas on patients suffering from diabetes. Telehealth refers to the systematic provision of healthcare services over physically separate environments via Information and Communications Technology (ICT) and distinguishes between four main dimensions/ domains of Telemedicine as follow: Tele-collaboration, which refers to interactions between (facility-based or mobile) onsite and remote healthcare professionals for clinical purposes e.g. referral, co-diagnosis, supervision or case review. The distinguishing feature is that healthcare professionals are involved at both ends of the interaction and a patient may or may not be involved in the same Telemedicine interaction. Tele-treatment, which refers to interactions between remote healthcare professionals and patients/ caregivers for the purposes of direct clinical care. The distinguishing feature is that a patient or caregiver is involved directly at one end of the interaction and this creates (or presupposes the existence of) a professional-patient relationship. Tele-treatment is used in the remote delivery of primary care and many forms of speciality care. Tele-monitoring, which refers to biomedical and other forms of data collection directly from patients (or through caregivers) by remote systems, which are used by healthcare professionals for clinical purposes such as vital signs monitoring and home nursing. Tele-monitoring is used in remote chronic disease management. The distinguishing feature is that a healthcare professional or organisation is engaged at one end. Another feature of Tele-monitoring is that it need not create (or presuppose the existence of) a professional-patient relationship even though the healthcare organisation as a whole might ow a duty of care to the patient. Tele-support, which refers to the use of online services for non-clinical (ie educational and administrative) purposes to support the patient, and caregiver. The More Independent programme run by Philips and the Liverpool Clinical Commissioning Group (CCG) provided telehealth services for 1,808 patients recruited from the primary care setting in Liverpool. The study showed reductions in emergency admissions and secondary care costs (in comparison with the control group) ranging from 22% to 32% for patients with above average risk (25% or more). Patient reported outcomes (PRO) also show that 90% of patients feel more in control, have gained confidence and/or feel better able to cope with their condition. However, there has been no such large scale study done in Singapore to study the impact of telehealth on the disease progression, healthcare utilisation and cost of care for diabetic patients in the primary care setting. As such, an evaluation of a prospective telehealth programme, i.e. Optimizing care of Patients via Telehealth In Monitoring and Augmenting their control of Diabetes Mellitus (OPTIMUM) is being planned for in SingHealth Polyclinics. The current standard of care comprises on-site measurements of clinical parameters and education in a usual outpatient clinic setting. The telehealth programme comprises remote patient monitoring, education, individualised on-line health coaching and timely interventions provided by primary healthcare professionals in polyclinics. The proposed Philips VitalHealth solution incorporates telehealth-enabled chronic disease management and care coordination. The telehealth-enabled chronic disease management programme is customised for individuals with chronic diseases and aims to provide timely intervention to prevent disease deterioration, increase compliance to treatment regimen (e.g. medication), and most importantly, engage participants to better manage their own care. On the insurance front, there are many gaps present in the insurance industry today with regard to chronic diseases, and to this end, Reinsurance Group of America (RGA) is interested to jointly study the effectiveness of a telehealth programme on diabetic patients, so that they can develop new health insurance products that can meet that insurance gap.
