Background & Methods

This comparative study at Chandaka Medical College's Kangaroo Mother Ward, Larkana, evaluated the diagnostic accuracy of the BEMPU TempWatch against a standard mercury thermometer as the reference standard for hypothermia detection in low-birth-weight newborns. 100 LBW newborns were enrolled and 1,080 paired temperature readings were collected and analysed.

  • 1The TempWatch achieved 98.60% sensitivity — correctly identifying nearly all hypothermic episodes detected by the mercury thermometer reference.
  • 295.82% overall accuracy and a high NPV (95.11%) confirm that a non-alert from the device reliably indicates a normothermic infant.
  • 390% of enrolled LBW newborns experienced at least one hypothermic episode, underscoring the prevalence of the problem in this setting.
  • 4The comparative diagnostic performance supports TempWatch as a reliable substitute for intermittent thermometer readings in routine KMC ward monitoring.

Why This Matters

Pakistan has one of the highest rates of neonatal hypothermia globally, and access to trained health workers for frequent thermometer monitoring is limited. This study provides strong evidence from a Pakistani KMC ward that the TempWatch is a highly accurate, continuous alternative to intermittent mercury thermometry, making it particularly suited for resource-constrained settings.
