A qualitative study of the experiences of insulin use by older people with type 2 diabetes mellitus

There is a rising prevalence of type 2 diabetes among older people. This population also suffers from co-morbidity and a greater number of diabetes related complications, such as visual and cognitive impairment, which can potentially affect their ability to manage insulin regimens. Understanding the experiences of older people when they transition to insulin will help the development of healthcare interventions to enhance their diabetes outcomes, overall health and quality of life.

The aims of this exploratory study were to (1) understand the experiences of older people with type 2 diabetes in relation to insulin treatment initiation and management and (2) use this understanding to consider how the insulin management support provided to older people by healthcare providers could be more tailored to their needs.

A qualitative study using semi structured (remote) interviews with older people with diabetes (n = 10) and caregivers (n = 4) from the UK. Interviews were audio recorded and transcribed, and framework analysis was used to analyse the data.

Three main themes, along with six subthemes, were generated from the study data. Participants generally felt at ease with insulin administration following training, yet some reported feelings of failure at transitioning to insulin use. Participants were also frustrated at what they perceived were insufficient resources for effective self-management, coupled with a lack of professional interest in optimising their health as older people. Some also expressed dissatisfaction regarding the brevity of their consultations, inconsistent information from different healthcare professionals and poor treatment coordination between primary and secondary care.

Overall, the study emphasised that older people need better support, education and resources to help manage their insulin use. Healthcare professionals should be encouraged to adopt a more individualised approach to supporting older people that acknowledges their prior knowledge, physical and psychological capabilities and motivation for diabetes self-management. In addition, better communication between different services and greater access to specialist support is clearly needed for this older population.

An integrated care pathway for insulin use in older people could be considered. This would include an assessment of the older person's needs and capacity on their initiation to insulin; targeted education and training in self-management; timely access to appropriate emotional and peer support resources; care plans developed collaboratively with patients; and individualised glucose targets that recognise the needs and preferences of the older person.
