Unique Swedish diabetes study shows how insulin pumps impact quality of life

26.03.2013
Being treated for diabetes with an insulin pump, an aid that is attached to the body to provide a continuous supply of insulin, has a strong impact on a person’s quality of life.

The pump can be a lifeline, but also a bothersome shackle. This is shown in a unique long-term study performed at the Academy of Health and Society, Dalarna University, Falun, Sweden in collaboration with the Clinic of Internal Medicine at Falun Hospital as well as Uppsala University and Umeå University.

The finding is part of a larger study where, for four years, researchers followed a group of adults with type-1 diabetes being treated with an insulin pump. The group’s blood glucose levels, in terms of HbA1c, and their satisfaction with the treatment were examined via blood samples and surveys, respectively.

The researchers then continued their long-term monitoring with interviews, after the subjects had been using an insulin pump for more than five years. The qualitative interview method has come to be a more and more important complement to traditional research methods in recent years.
There have only been a few such studies in the world. Qualitative methods yield a good picture of how the individual perceives and deals with his/her everyday life with a life-long disorder.

The results of the interviews evinced a pattern that could be divided into various themes. The insulin pump was perceived to be a lifeline in the sense that it brought greater independence, greater control of the subject’s own life situation, and that life had become normalized. On the other hand, the pump was perceived as being a shackle, meaning that the subject was dependent on the technology, felt stigmatized, and was weighed down by the disease. Among interviewees, some had a generally favorable view of the treatment with an insulin pump, while others oscillated between a favorable and an unfavorable view, with a third group expressing a predominantly negative view. These themes and views could not be related to blood glucose levels, which indicate that it is not enough to measure health based solely on medical examination methods. To get a better understanding of, and a more holistic picture of health and quality of life, it is necessary to analyze narratives from the individual subjects’ own perceptions, both as medical parameters and as health surveys.

In the interviews Janeth Leksell, one of the researchers and a lecturer at the Falun campus of Dalarna University, could hear descriptions of the insulin pump like the following:
- My first step toward better self-esteem
- The pump means freedom and flexibility

But also:
- I like dresses that show your figure, but it’s hard to wear them with a pump. At home I often put the pump in my bra, so I have three breasts.

- The pump can feel like a shackle. You feel you’re locked into something.

Caring staff needs to be conscious of how the insulin pump affects the everyday lives of patients, lives that are not only about diabetes. The findings of this study may provide guidance and a platform for diabetes nurses and physicians when they meet with and try to support patients living with insulin pumps, according to Anna Garmo, the diabetes nurse who directed the study.

Facts:
46 adults with type-1 diabetes who switched from treatment with multiple-daily injections with insulin pens to an insulin pump were monitored for glycaemic control and treatment satisfaction, Garmo A, Garmo H, Ärnlöv J, Leksell J. Long-term treatment effects of insulin pump therapy. Pract Diab Int 2011; 28: 295–299. The authors conclude that both glycaemic control and treatment satisfaction improved and remained at the improved level during the four-year follow-up period, following the switch to an insulin pump.

In the spring of 2009, 16 of the participants in the earlier study were interviewed, all having used an insulin pump for 5–9 years. At the time of the interview, the subjects were aged 29–65 years. The purpose was to find out their perceptions of insulin pump treatment in everyday life. The interviews took 30–45 minutes and were analyzed using qualitative content analysis as laid down by Graneheim & Lundman.

The findings show that the pump can be experienced both as a lifeline and as a shackle. Good or unsatisfactory glycaemic control does not seem to have any association with these perceptions.

The subjects could be divided into three groups. HbA1c in the group that had a positive view of insulin pump treatment varied between 41-70 mmol/mol. In the group with a negative view, HbA1c varied between 32-72 mmol/mol, and in the group with more mixed views, HbA1c varied between 47-68 mmol/mol. However, the number of subjects is so limited that no far-reaching conclusions can be drawn. Nevertheless, the findings do indicate that analysis of glycaemic control does not reveal everything about a patient’s quality of life.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
