SUMMARY

A population-based approach to the estimation of diabetes prevalence and health resource utilisation

James Smith, Gary Jackson, Brandon Orr-Walker, Rod Jackson, Siniva Sinclair, Simon Thornley, Tania Riddell, Wing Cheuk Chan

This study showed that diabetes is common in Counties Manukau and throughout the northern region, particularly in M ori and Pacific communities. It combined data that is normally used for administrative purposes with two other sets of data, to look at diabetes rates and the use of healthcare resources. All data were adjusted to avoid identification of individuals. This method has the advantage of providing comprehensive information about diabetes in a way that is timelier and less expensive than traditional survey methods, allowing better planning for the diabetes epidemic.

SUMMARY

Ethnic disparities in causes of death among diabetes patients in the Waikato region of New Zealand

Grace Joshy, Chanukya Kamalinie Colonne, Peter Dunn, David Simmons, Ross Lawrenson

Maori diabetes patients experienced significantly higher risk of mortality compared with Europeans with diabetes. Compared with European diabetes patients, Maori diabetes patients are more likely to die from cardiovascular disease, cancer and renal disease. Maori with diabetes are more likely than Europeans with diabetes to have diabetes reported on death certificates. The results suggest that the under-coding of diabetes on death certificates in New Zealand has not improved and continues to be a major limitation for routine mortality analysis solely based on these codes. Mortality among diabetes patients in New Zealand would need to be compared with that among people without known diabetes, to estimate the true burden due to diabetes.

SUMMARY

Exploring physical and psychological wellbeing among adults with Type 2 diabetes in New Zealand: identifying a need to improve the experiences of Pacific peoples

Charlotte A M Paddison

In this study we explored levels of physical and psychological wellbeing among adults with Type 2 diabetes in New Zealand. Our results showed that the majority (58%) of people in this study had difficulty achieving good control of their diabetes and did not meet the clinical targets set by health professionals. We already know that physical health outcomes for people with Type 2 diabetes vary by ethnicity; our study shows that psychological outcomes such as diabetes-related distress also differ across ethnic groupswith Pacific peoples worst affected. Our findings show that we need to improve the experiences of Pacific peoples with Type 2 diabetes. This includes improving metabolic control, and also working with Pacific patients to address any concerns about medication and to reduce emotional distress about diabetes.

SUMMARY

Implication of using estimated glomerular filtration rate (GFR) in a multi ethnic population of diabetes patients in general practice

Grace Joshy, Tesa Porter, Clem Le Lievre, Jane Lane, Mike Williams, Ross Lawrenson

This study looked at the prevalence of chronic kidney disease among diabetes patients in New Zealand. Estimated Glomerular Filtration Rate (eGFR) is increasingly used as a marker for identifying early renal failure. This study measured the agreement between two equations commonly used in the calculation of eGFR. There were significant differences in agreement between the two equations: the MDRD and the CG. While CG equation identifies more European of both genders, more M ori females were identified by MDRD. MDRD equation may be overestimating CKD among M ori females. Each ethnic subpopulation may need to be validated separately, and by gender.

SUMMARY

Standardisation of reporting haemoglobin A1c: adoption of the New Zealand Society for the Study of Diabetes (NZSSD) position statement

Chris Florkowski, Michael Crooke

New Zealand, in line with other countries has now implemented a system of new units for reporting HbA1c for monitoring long-term glucose control in diabetes. Our paper traces the background and rationale for this important change.

SUMMARY

How well does routine hospitalisation data capture information on comorbidity in New Zealand?

Diana Sarfati, Sarah Hill, Gordon Purdie, Elizabeth Dennett, Tony Blakely

Comorbidity refers to diseases or disorders that coexist with a disease of interest. Comorbidity is common and it is being increasingly recognised as being important in health-related research and policy. This paper compares routinely collected comorbidity data (collected by coders based in District Health Boards and sent electronically to NZ Health Information Systems) with comorbidity data collected directly from patients hospital notes by a physician. We found that although (expected) differences in these two sources of data exist, administrative data provides a useful and relatively accessible source of information on comorbidity in New Zealand.
