New guidelines for diagnosis of gestational diabetes: Pathology-based impact assessment

Abstract

Background:A recent study indicated an average of 19.5% abnormal oral glucose tolerance in antenatal clients per year.Aim:The purpose of this study was to determine the impact on gestational diabetes cases due to new guidelines for diagnosis and classification of hyperglycaemia in pregnancy.Materials and Methods:This study reviewed the archived clinical pathology data on oral glucose tolerance tests performed between January 1999 and December 2008 on antenatal clients (N = 615). The cases were reviewed to determine changes if any in percentage of gestational diabetes due to new guidelines.Results:Over the 10 years period, a yearly average of additional 10.8% antenatal cases suggestive of gestational diabetes was observed due to the new recommended thresholds. Further, the average yearly incidence would have increased from 8.8 cases to 16.2 cases, which translates to almost 46% increase in the prospective numbers of gestational diabetes.Conclusions:This report presents the extent of how the new recommended guidelines for diagnosis and classification of hyperglycaemia in pregnancy could increase the prevalence of gestational diabetes. It also provides pathology-based evidence for the epidemiology of gestational diabetes mellitus and allows for planning the costs that would be attendant to the full implementation of the new guidelines.

Continuous quality improvement and metabolic screening during pregnancy at primary health centres attended by Aboriginal and Torres Strait Islander women

“…19 However, few women in this study with an abnormal BMI had a management plan, which may reflect suboptimal action taken, a lack of documentation of the actions taken, or both. Excess weight gain increases pregnancy 21 may partially resolve these problems, the number of women diagnosed with GDM will also increase, 22 with potential resource implications for PHCs.…”

Satisfaction with diagnosis process for gestational diabetes mellitus and risk perception among Australian women

“…More recent guidelines base their recommendations on pregnancy outcomes, have a lower fasting glycemic threshold (≥ 5.1 mmol/L), and an additional 1‐hour glucose level for diagnosis (≥ 10.1 mmol/L) [3]. If these new guidelines are globally adopted, the number of diagnoses would increase by approximately 50% [8]. This increase could have significant implications for service burden and healthcare costs, and might affect the diagnosis and treatment of GDM.…”

Diabetes Gestacional e o Impacto do Actual Rastreio

“…Na nossa amostra, os autores concluíram que as características maternas foram semelhantes nos dois anos. 10 Farah et al concluí-ram que este rastreio se associou a um aumento da taxa de diagnóstico de 10,1% para 13,2% quando comparado com o rastreio anterior.…”
