Plain English Summary

Background and study aims
Gestational diabetes mellitus (GDM) is an impaired glucose (blood sugar) tolerance with onset or first recognition during pregnancy.If GDM is untreated it can lead to serious complications such as stillbirth. There are normally certain protocols in hospitals on how GDM is dealt with. Usually the management of gestational diabetes patients involves the patient being taken over by the diabetologist from the diagnosis at birth. Researchers have come up with a new protocol. In this new organizational protocol, diabetes counseling with the diabetologist is only foreseen in case of need of insulin (that controls blood sugar levels) therapy. This protocol was compared to the previous one, which instead provided for the presence of the diabetologist both for the first evaluation and the monitoring. With the same clinical outcomes there is an important reduction in the number of visits to the diabetologist. The aim of the present study is to evaluate whether the application of a new organizational protocol for the management of women with gestational diabetes predominantly conducted by a nurse and dietician can be pursued without affecting the quality of care. The aim of this study is to create a mainly nurse/dietitian-based GDM management protocol to reduce medical examinations without affecting clinical and welfare quality.

Who can participate?
Pregnant women aged 18 to 45 who do not have type 1 or type 2 diabetes.

What does the study involve?
Participants are allocated to two groups.The first group is based on a traditional protocol with patients’ blood glucose constantly checked by a Diabetologist. In the second structured group, participants are only referred to a Diabetologist if they required insulin therapy. Participants are followed up to compare the two protocols and see how the blood glucose is monitored and if the number of medical visits participants attends.

What are the possible benefits and risks of participating?
Participants may benefit from better monitoring. There are no direct risks with participating.

Where is the study run from?
Departements of UOC Malattie Metaboliche E Uo Ostetricia E Ginecologia (Italy)

Gestational diabetes


Participant are not randomised since the control group is the group of patients before the protocol. The duration of intervention is the pregnancy period and starts at the diagnosis moment and finishes with the delivery.

The study does not need randomization since the measure is not taken on two different therapies but on two different organizational protocols P1 and P2, whereas the same therapy was used (the only pharmacological therapy involved was insulin) with the same assessment of blood glucose data.

Two different organizational protocols were analysed: The first group of patients was based on a traditional protocol (P1: 230 pts) with patients’ blood glucose constantly checked by a Diabetologist. In the second group P2 was applied (P2: 220 pts), and patients were only referred to a Diabetologist if they required insulin therapy.

Organisational Protocol 1 (P1): for this protocol, the Diabetologist manages the entire process even if the patient does not require insulin therapy. Therefore, a nurse and a dietitian, if required, work together under the guidance of a Diabetologist.
Organizational Protocol 2 (P2): for this protocol, the Diabetologist intervenes only if the patient requires insulin therapy.
Total duration of the study is 2 and a half years.

Participants are invited, as described in the protocol, to do a Glucose Tolerance Test (GTT) after 12 weeks after delivery and to show results to their primary care physician. The primary care physician evaluates the need to send the person back to the diabetologist.

Drug names

Primary outcome measure

Hypoglycemia is measured using their personal glucose monitor when they feel symptoms, as instructed.

Secondary outcome measures

Number of medical visits is measured using patient number of recorded accesses in the Hospital booking system.
