Uncertainty and certainty: perceptions and experiences of prediabetes in New Zealand primary care - a qualitative study

Introduction. Prediabetes is the asymptomatic precursor to type two diabetes mellitus, a significant and growing public health problem in New Zealand (NZ). Little is known about how general practitioners (GPs) and nurses view prediabetes care, and similarly little is known about how people with prediabetes view their condition and care. Aim. This study aimed to investigate the views of NZ GPs and nurses, and people with prediabetes about prediabetes and its management. Methods. This was a mixed qualitative methods study that is part of a randomised control trial of a prediabetes intervention. Results. Three key themes emerged from the health professional data (GPs and nurses) and another three themes emerged from people with prediabetes data. GPs and nurses were uncertain about the progression of prediabetes; they felt prediabetes was not a priority and they were unsure about what to advise. People with prediabetes were uncertain about the diagnosis and information given to them; they were unsure about what to do about prediabetes and they found lifestyle change hard. Discussion. GPs, nurses and people with prediabetes, expressed much uncertainty, but also some certainty about prediabetes. All were certain that prediabetes is common and increasing and that sustained lifestyle change was very difficult. But uncertainty prevailed about whether, in reality, prediabetes could be stopped, who would be most likely to benefit from lifestyle interventions and how best to achieve these. Older Maori and Pacific women were keen to promote lifestyle change and this appeared best done through Maori and Pacific peoples' organisations by means of co-designed interventions.
