Brief Summary:

When women with diabetes become pregnant it is particularly important to control blood sugar levels to prevent complications. Women are advised to test their blood glucose levels seven times a day and to attend antenatal and diabetes clinics every 1-2 weeks throughout the pregnancy. For those living in rural areas in the North and West of Ireland getting to a hospital specialising in the management of diabetes and pregnancy on such a regular basis can be a challenge.

Telemonitoring provides a possible solution to this problem by allowing patients to monitor their vital signs at home and transmit the information via telephone to their healthcare provider. If women could be safely monitored remotely for every other appointment it would mean that they would only need to visit the hospital once a month on a routine basis but with the option of attending the hospital if the remote telemonitoring indicated that this were necessary.

The aim of this study is to assess the feasibility and the acceptability of using remote telemonitoring facilities between antenatal women with gestational diabetes and the diabetes team and the possibility of replacing alternate diabetic review clinics with remote telemonitoring. In addition this study will explore the feasibility of running a full randomised control trial of this topic.

Women will be asked to monitor their blood sugar levels seven times a day which is part of usual care. However those in the remote telemonitoring group will be asked to measure their blood sugar using a meter that can transmit the results via a telephone line and to transmit them weekly. They will also be asked to measure their blood pressure and weight weekly and to download these results weekly for a health care professional to review. These results will be reviewed on a weekly basis by a health care professional who will contact the patient if necessary to discuss the results. Women will be followed-up from the date of diagnosis through to delivery.

Both staff and patients will be asked to give their views on the safety and acceptability of remote telemonitoring through questionnaires, focus groups or interviews. The management decisions made on reviewing the intervention group in clinic and reviewing remote telemonitoring results will also be recorded. In order for remote telemonitoring to be a viable replacement for clinic review it must allow health care professionals to make comparable management decisions. Clinical data will be collected in order to provide descriptive statistics for those who take part and to ensure that this information could be collected in any future Randomised Control Trial (RCT) looking at this topic.

Arm Intervention/treatment
Experimental: Telemonitoring
The telemonitoring group will receive usual care but be asked to download their blood sugar readings and take a blood pressure and weight measurement each week. This will be reviewed by their diabetes health care team to assess the possibility of replacing alternate anti-natal/diabetes clinics with telemonitoring review in a future study. Acceptability to staff and patients will be assessed through a questionnaire (patients only) and qualitative interviews.
Device: Telemonitoring
Use of telemonitoring facilities to monitor weight, blood pressure and blood sugar during pregnancy complicated by gestational diabetes

Active Comparator: Control group
Control group will consist of usual care and review at clinic.
Other: Control
The control group will receive usual diabetes/antinatal care. The outcomes from usual care will be compared with the outcomes from the telemonitoring group in order to ensure that it provides comparable care.
Other Name: Usual care

Primary Outcome Measures :
  1. Patient satisfaction [ Time Frame: At 36-39 weeks gestation ]

    The previously validated 'Telemedicine satisfaction and usefulness questionnaire' will be used to assess patient satisfaction with the telemonitoring service.

    Qualitative interviews exploring the patient experience of telemonitoring will also be carried out and then analysed using the framework approach. An adapted version of this questionnaire looking specifically at the use of a blood glucose meter will be given to the control group.

  2. Health care staff satisfaction [ Time Frame: At completion of the study estimated to be January 2013 ]
    The professionals involved in caring for the women using remote telemonitoring technology in antenatal or diabetes clinics will be invited to take part in a focus group at each site. If it is not possible to arrange a time and place suitable for staff in order to hold a focus group it may be necessary to hold one to one structured interviews with staff. The questions used in the focus group will aim to assess the acceptability of telemonitoring to health care staff who use it.

  3. Management decision comparison [ Time Frame: At weekly clinic or telemonitoring review from time recruited into study to delivery, estimated at an average of twelve weeks. ]
    Weighted kappa will be used to meaure the level of agreement in between clinic and telemonitoring review management decisions (in excess of the amount of agreement that we would expected by chance). This will allow the determination of inter-rater, intra-rater and inter-institutional agreement between clinic and telemonitoring review management decisions.

Secondary Outcome Measures :
  1. HbA1c [ Time Frame: Monthly for duration of participation in study, estimated at 2-3 months ]
    HbA1c mmol/l and IFCC units

  2. Mean fasting blood glucose [ Time Frame: Weekly for duration of participation in study, estimated at 12 weeks ]
    mmol/l plasma glucose

  3. Blood pressure [ Time Frame: Weekly for duration of participation in study, estimated at 12 weeks ]

  4. Gestational age at delivery [ Time Frame: At delivery ]
    Gestational age in weeks at delivery

  5. Type of delivery [ Time Frame: At delivery ]
    Vaginal or Caesarean section

    Presence or absence of any pre-eclampsia

  7. Documented problems with pregnancy [ Time Frame: At delivery ]
