National survey on the execution of the oral glucose tolerance test (OGTT) in a representative cohort of Italian laboratories

Abstract

For the Italian laboratories investigated, relevant variability was highlighted for performance of the OGTT in general and GDM screening in particular. A variable relationship between laboratories and diabetes centres was also detected, which might represent a relevant indicator for the need for rationalisation or standardisation of the method for performing an OGTT. These data highlight the need for greater collaboration between these different bodies. We suggest that other similar investigations should be carried out in other countries within the framework of the IFCC Global Campaign on Diabetes Mellitus.

Gestational diabetes mellitus: Confusion among medical doctors caused by multiple international criteria

“…Due to the multiple methods available, the disparity in approach, within and between hospitals and different countries is well documented . Multiple surveys (1990–2014) among countries and within countries like Australia, the UK, Italy, Europe, Sweden and Scotland have found similar differences. The problem highlighted by this study is that not much has changed despite many years of research on GDM with the differences persisting over the last few decades.…”

Source of Patient Information: Physician or Laboratory? An Audit of Patient Information on OGTT protocol

“…Sample size was calculated based on previous study on pregnant woman (5) using the data published population proportion: 20%, expected population with low compliance to OGTT :40%. Calculated sample size is 250(alpha error 5% and power 80%) A semi structured questionnaire was administered to each patient covering all aspects of the protocol.…”
