How to track fluid balance in a hospital without paper charts?

BedSync replaces paper fluid balance charts with a mobile app that uses voice capture and barcode scanning. Nurses speak fluid entries like '350 mL urine, dark amber' and the app automatically parses volume, type, and metadata. Barcode scanning identifies IV bags via FDA GUDID and oral fluids via Open Food Facts. All data syncs to the EHR via FHIR R4.

How to reduce nursing documentation time for fluid balance?

Voice-enabled clinical documentation reduces charting time by 50% compared to keyboard entry (Nuance, 2024). BedSync applies voice intelligence specifically to fluid I/O tracking — nurses tap, speak, and confirm rather than typing into the EHR. This eliminates end-of-shift catch-up charting and the 30-60 minutes of 'ghost overtime' nurses spend finishing documentation.

How to detect acute kidney injury early using urine output?

BedSync continuously calculates AKI risk using KDIGO 2012 criteria based on urine output: Stage 1 (<0.5 mL/kg/hr for 6h), Stage 2 (<0.5 for 12h), Stage 3 (<0.3 for 24h). A proprietary pre-alert system warns when UO drops to 0.5-0.7 mL/kg/hr for 3+ hours. Research shows UO changes can signal AKI 2.4-46 hours before creatinine rises (Willner et al., 2021).

How to integrate fluid balance data with Epic or Cerner EHR?

BedSync exports structured FHIR R4 data via Redox, connecting to Epic, Cerner (Oracle Health), and other major EHR platforms. Verified I/O data can be pushed to the patient's chart directly from the shift handoff screen, eliminating double-charting.

How accurate are manual fluid balance charts in hospitals?

Manual fluid balance charts are highly inaccurate. Only 12% of patients with clinical indication had documentation (Alexander & Allen, 2011). 25-35% of charts contain calculation errors, with cumulative errors reaching up to 2,405 mL (Davies et al., 2014). 75% of patients developing AKI had incomplete fluid records (Joslin et al., 2015). The EHR Flowsheets module scores just 62.13 on usability.

What is the cost of acute kidney injury in hospitals?

AKI costs $7,933+ per episode in incremental costs, driven by extended stays and dialysis. Nationally, hospital-acquired AKI costs $5.4-$24 billion annually (Silver et al., 2017). 57.3% of ICU patients develop AKI, with mortality of 25.7% vs 4.9% for those without (Hoste et al., 2015).

The Charting Crisis

Half of fluid balance charts are never completed.

The ones that are? 25–35% contain calculation errors large enough to mask kidney injury, with cumulative errors reaching up to 2,405 mL. Only 12% of patients ordered for I/O monitoring actually had documentation. BedSync replaces manual charting with voice and vision capture. Speak it, scan it, sync it to the EHR.

The Solution

Speak. Scan. Sync.

Voice Capture

Tap-to-talk fluid logging. Gloves-on, minimal screen time. Say “350 mL urine, dark amber” and BedSync parses fluid type, volume, and clinical metadata automatically.

Barcode Intelligence

Barcode scanning cascades through three databases: a local formulary, the FDA GUDID registry for IV fluids, and Open Food Facts for oral products. Automatically identifies fluid type, volume, and water equivalents.

Writes Back to Your EHR

BedSync isn’t another silo. It exports structured FHIR R4 data via Redox, connecting to Epic, Cerner (Oracle Health), and other major EHR platforms. Push verified I/O data to the patient’s chart from the handoff screen. No double-charting.

Two Ways to Capture

Phone or Pod. Same Pipeline.

Every unit is different. Some nurses want a screen. Others want to speak and move on. BedSync gives you both.

Mobile App

A locked-down iPad or iPhone at the bedside station. Tap the mic, speak your entry, confirm the parsed result on screen. Full dashboard with patient list, fluid balances, KDIGO staging, and shift handoff — all in your hand.

Best for: Units that want real-time visibility and on-screen confirmation at point of care.

Wearable Mic Pod

A small, clip-on puck worn on the lanyard or scrubs. Tap once to record, tap again to stop. Haptic buzz and LED confirm the entry was captured. Parsed results queue on the unit dashboard for batch review — no screen needed at the bedside.

Best for: High-acuity units where hands are occupied and speed matters more than screen interaction.

Both devices connect to the same on-premise server inside your hospital. Voice is processed locally — no patient audio ever leaves your network. Entries from either device feed into the same patient record, the same KDIGO engine, the same EHR export.
