Authors' conclusion

Using HPI-85 popup alerts does not provide additional prediction time over MAP-alerts in the 70 to 75 mmHg range, but they may be preferred due to higher PPV values.

0.58 min

As reported in the abstract

Observational data: associations, not effects.

Further findings

PPV — HPI-85 popup
55.6 (95% CI 55.4–55.8) %
  • PPV: MAP-75 20.5 (95% CI 20.3–20.6) %

Missed hypotensive events

Similar: between one to three percent

Instant HPI-85 vs MAP-72 alerts

Comparable performance, both suboptimal PPV around 30%

MAP-alerts with 40-s time-dependence

Differences across the three metrics levelled, aligning closely with HPI-85 popup alerts
