Text-message Reminders to Increase Rates of Postpartum Diabetes Screening in Women With Gestational Diabetes

2015-06-04 00:08:22 | BioPortfolio


Purpose: The purpose of this study is to see whether a text-message reminder system will increase the number of women who complete their diabetes screening after delivery.

Study Design: Prospective randomized control trial

Hypothesis: Gestational diabetics will be significantly more likely to follow up with their postpartum screening for diabetes if they receive text-message reminders to set up their lab appointment compared to those who receive usual care.


Eligible participants will be recruited after delivery while on the postpartum ward. Recruitment will be conducted by the PI or a member of the study team. After informed consent is obtained, the patients will be randomized into one of two study groups: the intervention group or the control group. Women in the intervention group will receive a test text-message reminder at the time of enrollment. They will then receive a text-reminder to schedule their oral glucose tolerance test at 6 weeks postpartum, with further reminders at 3 months and 6 months if they have not completed their testing. Women in the control group will only receive the test text-message reminder. The PI or member of the study team obtaining the informed consent will verify the participant has received the text-message prior to completing enrollment. A computer-generated randomization list will be generated according to intervention vs. control group. Simple randomization will be used for the purposes of this study. 316 participants will be recruited based on the sample size calculations already performed. One group of 316 randomized opaque envelopes will be prepared. These sealed envelopes will be stored in a secured designated area at Tampa General Hospital. Once a patient has agreed to participate and is consented an envelope will be selected from the next sequentially numbered envelope and the number on the envelope will be recorded on their study sheet. Enrollment will continue until 316 participants have been recruited.

Medical and Biotech [MESH] Definitions

Diabetes mellitus induced by PREGNANCY but resolved at the end of pregnancy. It does not include previously diagnosed diabetics who become pregnant (PREGNANCY IN DIABETICS). Gestational diabetes usually develops in late pregnancy when insulin antagonistic hormones peaks leading to INSULIN RESISTANCE; GLUCOSE INTOLERANCE; and HYPERGLYCEMIA.

A condition of fetal overgrowth leading to a large-for-gestational-age FETUS. It is defined as BIRTH WEIGHT greater than 4,000 grams or above the 90th percentile for population and sex-specific growth curves. It is commonly seen in GESTATIONAL DIABETES; PROLONGED PREGNANCY; and pregnancies complicated by pre-existing diabetes mellitus.

The state of PREGNANCY in women with DIABETES MELLITUS. This does not include either symptomatic diabetes or GLUCOSE INTOLERANCE induced by pregnancy (DIABETES, GESTATIONAL) which resolves at the end of pregnancy.

Communication between CELL PHONE users via the Short Message Service protocol which allows the interchange of short written messages.

Trophoblastic growth, which may be gestational or nongestational in origin. Trophoblastic neoplasia resulting from pregnancy is often described as gestational trophoblastic disease to distinguish it from germ cell tumors which frequently show trophoblastic elements, and from the trophoblastic differentiation which sometimes occurs in a wide variety of epithelial cancers. Gestational trophoblastic growth has several forms, including HYDATIDIFORM MOLE and CHORIOCARCINOMA. (From Holland et al., Cancer Medicine, 3d ed, p1691)
