BEMPU Catches and Reduces Hypothermia (Internal Study)

Objective:  To show the utility of a new temperature monitoring device for hypothermia in neonates in the clinical and home settings in India. 

Study Design: Quantitative and Qualitative user feedback gathered from doctors and parents on device accuracy and acceptability. 

Setting: 27 NICUs and 16 homes in India.

 Subjects: 27 doctors, 24 families, and 93 neonates. 

Intervention: The subjects were given a hypothermia monitoring and alert device – the BEMPU Bracelet – during their critical neonatal development to monitor hypothermia 

Outcome Measures: Hypothermia cases measured by alarms in the clinic and home setting; doctor satisfaction measured by feedback; and parent compliance measured by feedback.

Results: In the Doctor Feedback Study, 67% of doctors used the device in their clinics or prescribed for home use to parents; 89% of doctors who used the device observed at least one case of hypothermia in the home or clinical setting; 89% of doctors who used the device recommend it to be used in their practice. In the Parent Feedback Study, 86% of families used this device in the NICU or postnatal wards and 84% of families continued use of the device in their home. 100% of the mothers who used the device used corrective care when the alarm sounded – care included kangaroo mother care, swaddling, and seeking medical intervention. 

Conclusions: Temperature monitoring devices for newborns are found to be useful in clinical and home settings. The BEMPU Hypothermia Alert Device is simple to use and recommended by doctors and parents.

Sensitivity and Specificity of the BEMPU Bracelet (Independent Study)

Introduction: In the home environment, low birth weight neonates are at high risk of becoming hypothermic if their temperatures are not consistently monitored. Hence, there is need for a tool that is simple and easy-to-use and helps families monitor their baby’s temperature after being discharged from the hospital. BEMPU Health offers the BEMPU Bracelet, a wearable device for neonates, which blinks with blue light when the neonate is normothermic (>36.5°C) and red light when hypothermic (<36.5°C).

Aim & Objective: To assess the diagnostic accuracy of the BEMPU Bracelet for detecting hypothermia in low birth weight neonates weighing less than 2000 grams.

Methodology: This was a descriptive study done in the step-down nursery of a tertiary health care hospital in India. Eligible neonates fulfilling the inclusion criteria were given the BEMPU Bracelet for a period of 24 hours. If a neonate became hypothermic, an audiovisual alarm, which includes sound and a flashing red light, was set off on the bracelet. The alarm signaled the mother to take temperature-corrective measures until the neonate became normothermic. Temperature corrective behaviors include kangaroo mother care (skin-to-skin contact), swaddling, or placing the neonate under a warmer. When the BEMPU Bracelet alarmed, the temperature was cross-checked with the neonate’s axillary temperature with a mercury thermometer. The total number of true positive, false positive, true negative and false negative temperatures was recorded for each neonate.

Results: A total of 460 neonates were screened for hypothermia using the BEMPU Bracelet. The overall prevalence of hypothermia was 20.3%. Sensitivity and specificity of the bracelet in diagnosing hypothermia was 98.6% & 95% respectively. The positive and negative predictive value of the bracelet was 83.5% and 99.6% respectively. The accuracy of the bracelet in diagnosing hypothermia was 95.8%.

Conclusion: The BEMPU Bracelet is an accurate screening tool for detecting hypothermia in neonates.

Weight Gain and Promotion of KMC (Collaborative Study)

Summary: The purpose of this study is to determine the relationship between the BEMPU Bracelet and uptake of Kangaroo Care.

Methodology: The study  patient diaries and weekly follow up appointments to gather data on weight, length, head circumference, and hours of KC per day. The study placed the BEMPU Bracelet on the wrist of ½ of neonates; the other half of neonates will be part of the control group and receive a placebo BEMPU Bracelet, which will not alarm, but will log temperature data.  Sample size was calculated by weight gain data collected from a sample pilot of the study, which showed the average weight gain for BEMPU Group and the Control Group as 31.54 and 17.36 grams per day over a 4 week period.

ResultsIn the BEMPU group, the average daily time spent doing KMC was significantly higher in first (3.02 v 1.96 h, p=0.016) and fourth (3.04 v 2.38 h, p= 0.094) weeks of discharge. There was an increase of weight gain in the BEMPU group on the fourth (28.3 v 22.9 g, p=0.057) week of discharge. The BEMPU Bracelet was found to be an effective intervention to promote newborn weight gain and parent adherence to Kangaroo Care, and it should be considered an effective intervention for LBW neonates discharged in the home.

BEMPU Catches Infection in the Home (Case Study)

For more information, check out this videoA NICU discharge baby in Bangalore used the BEMPU bracelet at home for three weeks.  The bracelet alarmed daily in the first week and the mother quickly learned how to properly swaddle the baby to make sure she was always warm. One night the device alarmed for more than straight six hours – the next morning the mother called the BEMPU team to find out what was wrong. We advised the mother to take the baby to the hospital. The baby was lethargic with blank stares when she arrived at the hospital.  The baby was diagnosed with a gastrointestinal infection. Because the infection was caught early, the baby was able to receive care in the hospital and has made a full recovery. She celebrated her first birthday with the BEMPU team.

BEMPU Catches Hypothermia During Transportation (Case Study)

A hospital in Kerala used the BEMPU Bracelet to monitor hypothermia in neonates in their ambulance during transportation in between centers. All neonates in the hospital who are transported are placed in a warming apparatus; however, the BEMPU Bracelet alarmed for this baby, which alarmed the health staff quickly. They realized that the air conditioning from the car was turned on and blowing on the baby, which made the baby hypothermic and set off the BEMPU alarm. *Since this case study, the BEMPU team has been interested in furhter studying hypothermia during transportation.

BEMPU Catches Hypothermia in the Hospital (Case Study)

A hospital in Maharashtra commonly uses the BEMPU Bracelet in the NICU for two days before discharging the neonate. There was an instance where the BEMPU Bracelet alarmed while the baby was in the warmer, and it alerted the hospital staff that the incubator was broken. The baby was quickly moved to a working incubator.

NHM Rajasthan Feasibility Pilot with BEMPU Bracelet (Independent Study)

*This study is still in progress, but you can find a brief summary here. For more information, you can e-mail us at 

Objective: The purpose of this study is to determine if the BEMPU Bracelet can be integrated into Rajasthan’s facility & Home Based Newborn Care Guidelines. The study was carried out by NHM Rajasthan, WISH Foundation, and BEMPU.

Methodology: Data was collected by nurses and data entry operators from 3 SNCUs and 7 PHCs who were trained by BEMPU and WISH. Over 300 babies were enrolled and given either a functional BEMPU Bracelet or a placebo Bracelet. Parents were trained in Bracelet usage and Kangaroo Care. Anthropometric data was collected weekly for the 4 weeks following a baby’s discharge.

Intermittent Findings: We have found that the Bempu group has a higher follow-up rate to weekly appointments and has a lower neonatal mortality rate. Feedback from doctors and patients has indicated that the device is effective in increasing KMC uptake.
