Insulin resistance insights revealed


Healthcare professionals can foster timely insulin initiation by supporting patients with realistic, accurate perceptions of diabetes and its treatment from day one.

A recent study1 provides insights into some of the ways health professionals (HCPs) can encourage people with type 2 diabetes (TD2) to start insulin, given research shows that one quarter of adults with T2D are unwilling to so, even if they’ve been told to by a health professional. The phenomenon known as psychological insulin resistance (PIR) can result in delays in treatment and poor health outcomes for people with TD2, including the risk of developing or worsening long-term diabetes complications.2

EMOTION1 is a global study developed to identify strategies to overcome concerns about insulin in researchers looked at 38 strategies used by HCPs to encourage people to start insulin therapy. Dr Elemer Balogh and colleagues3 analysed survey data for 125 UK adults with T2D who were either “not willing’ or “slightly willing” to be begin insulin when first asked to do so by their health professional.

Their findings show:

  • 84% of participants found that a demonstration of the injection process was helpful for starting insulin, including talking the patient through the entire process;
  • 82% reported that their HCP highlighting the benefits of insulin—explaining that it is a natural substance the body needs—was helpful; and
  • 81% reported that encouragement from their health professional to seek support and ask questions about injecting was helpful.

On the other hand, participants said an ‘authoritarian’ communication style, including repeatedly trying to convince them they should start insulin, made them feel less likely to do so, and to even discontinue use. This occurred in more than a third of patient encounters.

Making a difference to diabetes

Understanding the barriers to treatment intensification has been the focus of a research program run by Professor Jane Speight and Research Fellow Dr Elizabeth Holmes-Truscott at the Australian Centre for Behavioural Research in Diabetes (ACBRD). Working in partnership with Deakin University and Diabetes Australia, the ACBRD is the first national research and advocacy centre in Australia and internationally, dedicated to investigating the behavioural, psychological and social aspects of diabetes.

Dr Holmes-Truscott (pictured), who also co-ordinates the National Diabetes Services Scheme (NDSS) Starting Insulin (type 2 diabetes) National Priority Area,4 says many people for whom insulin is clinically indicated, are reluctant to begin for a variety of reasons.

“Our data5-10 shed light on the common experience of negative insulin perceptions among people with T2D and the impact of them on timely uptake and adjustments to insulin use. For example, in a sample of 313 Australians with non-insulin treated T2D9 we identified that negative attitudes are common and associated with greater emotional burden and negative attitudes to other medications. This suggests that identifying and addressing these issues early may help to improve receptiveness and adjustment to future treatment.

“Clinicians, including pharmacists, have a responsibility and a unique opportunity to start a dialogue about insulin, providing a chance for the person to raise their concerns and questions early.”

“In a primary-care based study10 of 261 adults with T2D, we identified that a quarter of adults, for whom insulin was clinically indicated, were “not at all willing” to start insulin if recommended while a fifth were “very willing”. Importantly, greater receptiveness—or willingness—and higher hbA1c predicted insulin initiation at 12 months.7 This suggests that interventions to promote timely insulin initiation must address psychological barriers to insulin and improve receptiveness,” Dr Holmes-Truscott tells the AJP.

“Recognising a significant problem, the NDSS launched the ‘Type 2 Diabetes: Starting Insulin’ priority area,4 led by Prof Speight—and we developed the freely available NDSS Starting Insulin booklet13 to support people interested in learning more about starting insulin and what it might mean for them. The booklet was designed to address psychological barries to insulin as well as support informed decision making,” she says.

The booklet was produced in consultation with adults with T2D as well as HCP advisors about its content and structure. “This process has helped us feel confident that it meets a need and is accessible to many Australians with T2D. We are also delighted to see a referral to the booklet in the RACCP clinical management guidelines and we’ve received feedback that health professionals are using the booklet during consultations.”

Addressing negative attitudes to insulin may also support optimal use of, and adjustment to, insulin beyond prescription, she adds.

“84% of participants found that a demonstration of the injection process was helpful for starting insulin, including talking the patient through the entire process.”

“Cross-sectional surveys of participants with insulin-treated T2D identified that negative perceptions remain common following insulin initiation and are associated with lower emotional wellbeing and self-efficacy, as well as higher perceived and experienced diabetes-related stigma.5,6 While our interview study8 of 19 people with insulin-treated T2D revealed both positive and negative consequences of ongoing insulin use. These included continued concerns about the potential or actual need to intensify treatment and its association with worsening health or personal failure. This research highlights the impact of psychological barriers to insulin beyond uptake and the need to identify and address ongoing, or new concerns throughout treatment progression.”

All HCPs have a role in this, she says.

“Each member of the HCP team plays an important role in fostering realistic and accurate perceptions of diabetes and its treatment. This starts from day one—communicating effectively and accurately during each consultation about the progression nature of diabetes and associated treatments. Clinicians, including pharmacists, have a responsibility and a unique opportunity to start a dialogue about insulin, providing a chance for the person to raise their concerns and questions early,” she says.

“It is important to normalise any concerns, provide a balanced response, and acknowledge that adjusting to new treatments can take time. There is no need to sugar coat it—we want to support people with T2D to make an informed decision about their treatment, and this, of course, means understanding both the risks and benefits.”

“A good place to start is by taking a look at the NDSS Starting Insulin booklet13 which includes responses to 11 frequently asked questions about insulin, drawing on salient psychological barriers to insulin.”

Having a keen interest in communication issues around diabetes, she believes the language we use when talking to and about people with T2D is critical.

“Language absolutely shapes our beliefs. From before diagnosis of T2D, how others—health professionals, media, family and friends—talk about diabetes can influence long-term perceptions of the condition, it’s treatment, and our own health identity. Early and ongoing education can foster realistic and clinically accurate perceptions of the role of insulin and the potential for changing treatment needs. Alternatively, inappropriate and inaccurate language can and does reinforce the perception that insulin, and other forms of treatment, are a merely consequence of an individual’s behaviour, for example. This stigmatising communication can be harmful,” she says.

Dr Holmes-Truscott has also undertaken research into other non-insulin injectable medications to see if similar negative attitudes and concerns exist.

“We’ve completed a novel interview study with people with T2D with recent experience of starting non-insulin injectable medication. We wanted to understand whether psychological barriers to insulin were similarly reported about other injectable diabetes medications. The findings will soon be published. In brief, participants reported that their initial perceptions of GLP-1RA injections were informed by their beliefs about insulin, including their concerns. However, many of these concerns were minimised following discussion with HCPs about the potential benefits of treatment or experience of such benefits.”

She also hopes the outcomes of her most recent research will be of benefit.

“We are also currently testing a novel online intervention11 to reduce psychological barriers to insulin therapy among people with T2D. Our pilot study12 revealed that the intervention was acceptable to participants. We now await results from a randomised controlled trial. If successful, we hope to make the intervention freely accessible in the future to support people with T2D starting insulin.”

The ACBRD has also developed a number of NDSS resources for people affected by diabetes and HCPs relevant to the behavioural and psycho social aspects of diabetes. For example, NDSS The Diabetes and Emotional Health Practical Guide, 2nd edition, 2020 (co-authored Prof Jane Speight) has been developed to support health professionals to identify, address and communicate about emotional problems during consultations with adults with type 1 and type 2 diabetes. It is complemented by a toolkit containing summary cards of several chapters, questionnaires, and leaflets for people with diabetes.
