Brief Summary

Second malignant neoplasms and cardiac late effects are primary drivers of serious non-recurrence morbidity and mortality in long term childhood cancer survivors. Cardiac late effects have been most prominently associated with exposure to high doses of anthracyclines or chest radiation. While increased recognition of late effects has resulted in risk-targeted therapy and reductions in use of high dose radiation and anthracyclines for many patients, these cardiotoxic exposures continue to be essential components of curative childhood cancer therapy. In addition, as survivors age they are increasingly susceptible to other general risk factors for cardiovascular disease recognized in the general population, such as hypertension, obesity, dyslipidemia, and diabetes. This study will evaluate a high blood pressure monitor (HBPM)-based intervention for the early detection of pre-hypertension and prevention of clinical hypertension in survivors of childhood cancer. Eligible and consenting participants will be randomized into one of three groups: GROUP 1: Instructed to measure blood pressure (BP) every day for 3 months. GROUP 2: Instructed to measure BP for 7 consecutive days once a month, for 3 months. GROUP 3: Instructed to measure blood pressure for 3 consecutive days each month, for 3 months. The randomization to the above groups will be done using sequential assignment of newly recruited participants based on a randomly ordered list. PRIMARY OBJECTIVE:

  • Evaluate the feasibility of High Blood Pressure Monitoring (HBPM) for three consecutive months using a remote blood pressure device provided to participants of the St. Jude Lifetime cohort (SJLIFE) protocol. SECONDARY OBJECTIVES:
  • Assess compliance with use of HBPM by measurement frequency, evaluating overall and defined minimum use in each of the three different groups.
  • Assess compliance with use of HBPM by cell phone status, evaluating those with and without a personal cell phone capable of connecting directly to the home blood pressure monitoring device via Wi-Fi or Bluetooth network.

Outcome Measures

Primary Outcomes (1)

  • Proportion of participants who meet or exceed defined minimum use of HBPM device by group

    The proportion of participants who meet or exceed the defined minimum level of compliance with recording of scheduled blood pressure measurements will be reported. Minimum use is defined as: Groups 1 and 2: Successful recording of 12 measurements (maximum 2 per day, one morning and one evening) over any 7 day period in at least 2 of the 3 months of the study. Group 3: Successful recording of two measurements each day (morning and evening) for three consecutive days, at least once in each of the 3 months of the study.

    From Day 0 through 3 months

Secondary Outcomes (4)

  • Compliance rate for the use of the HBPM device by group measurement frequency

    From Day 0 through 3 months

  • Proportion of participants who comply with the use of HBPM device by cell phone status

    From Day 0 through 3 months

  • Number of participants who fail to record any blood pressure measurements over the course of a month

    From Day 0 through 3 months

  • Proportion of participants by group who recorded at least 80% of scheduled measurements

    From Day 0 through 3 months

Study Arms (3)

Group 1: Daily for 3 Months

Participants randomly assigned to this group will be instructed to measure their blood pressure (BP) every day during the 3-month study period. BP reading will be taken using an iHealth Wireless Blood Pressure Monitor.

Device: iHealth Wireless Blood Pressure Monitor

Group 2: Daily for 1 Week/Month

Participants randomly assigned to this group will be instructed to measure their BP for seven consecutive days once each month during the 3-month study period. BP reading will be taken using an iHealth Wireless Blood Pressure Monitor.

Device: iHealth Wireless Blood Pressure Monitor

Group 3: 3 Consecutive Days Once/Month

Participants randomly assigned to this group will be instructed to measure their BP for seven consecutive days once each month during the 3-month study period. BP reading will be taken using an iHealth Wireless Blood Pressure Monitor.

Device: iHealth Wireless Blood Pressure Monitor

Interventions

Participants will be provided with an iHealth Wireless Blood Pressure (BP) Monitor and instructions for proper use (based on a standard protocol). The iHealth device pairs easily with a cell phone or other mobile device equipped with the iHealth app (freely available on app stores for both Apple and Android devices). Participants place the cuff on their arm and press start on their mobile device. The device measures BP using the oscillometric method and automatically downloads measurements and timing to a cloud-based server. Participants will be educated that individual BP readings can be highly variable and that any one high or low reading has little or no significance. They will also be encouraged not to measure their blood pressure more than twice in the morning and twice in the evening.
