The Hidden Cost of Incomplete Records
Most fire departments know their data quality isn't perfect. What most don't fully appreciate is how that incompleteness cascades into real operational and financial consequences.
A record with a missing arrival time isn't just one bad data point — it's an incident that can't be used in response time analysis, ISO PPC evidence, grant narrative justification, or NERIS compliance reporting. Multiply that by 15–30% of your records (a typical gap rate for cleared time and dispatch time), and you've lost a significant portion of your analytical foundation.
The Four Consequences of Poor Data Quality
1. Weakened Grant Applications
Grant reviewers are trained to look for data-backed justification. When your response time analysis has a sample size of 60% of your actual incidents (because 40% are missing timestamps), reviewers notice — or worse, your own analysis is misleading because the missing records aren't random. Long incidents, mutual aid responses, and overnight calls are disproportionately likely to have missing cleared times, which means your average response time appears faster than it actually is.
2. Reduced ISO PPC Credit
ISO evaluates response times at the 80th percentile. If your response time data is incomplete, ISO will either use a smaller sample (reducing confidence) or document the data gap as evidence of poor record-keeping — which itself affects your operations score. ISO auditors look at your data discipline as a proxy for your operational discipline.
3. NERIS Non-Compliance
The January 2026 NERIS mandate requires specific fields to be present. Missing dispatch times, null life safety fields, and blank primary actions are compliance failures — even if the incident was otherwise fully reported. Non-compliant data affects your department's standing with USFA and, increasingly, with FEMA grant programs that use NERIS data to assess need.
4. Bad Operational Decisions
If your data shows average response times of 6 minutes 30 seconds but 25% of your incidents are missing arrival times, you don't actually know your response time. The decisions you make about station coverage, staffing shifts, and apparatus deployment based on that number may be based on a systematically biased sample.
The Most Commonly Missing Fields
Across fire departments of all sizes, these are the fields most likely to be incomplete:
- Dispatch time — Missing when CAD doesn't automatically push dispatch timestamps to the RMS
- Cleared time — Missing when units clear without notifying dispatch, or when dispatch clears units without the RMS capturing it
- Controlled time — Rarely captured for non-fire incidents; often skipped even for fire incidents
- Life safety fields (injuries/fatalities) — Left null rather than zero on routine calls where nothing happened
- Primary action taken — Skipped on EMS and service calls
- Fire module fields (area of origin, cause) — Often blank when the incident is entered before the investigation is complete, and never updated
How to Fix the Most Common Problems
Dispatch Time: Automate It
The only reliable fix for missing dispatch times is a direct CAD-to-RMS integration that automatically writes the dispatch timestamp when the call is dispatched. Manual entry will always have gaps. If your RMS vendor and CAD vendor don't have an integration, this should be a top priority ask — or a deciding factor in your next system evaluation.
Cleared Time: Make It Required
In your RMS configuration, make cleared time a required field before an incident can be closed. If crews can close incidents without entering cleared time, they will — especially on busy shifts. A soft reminder doesn't work; make it a hard stop.
Life Safety Fields: Default to Zero
Configure your RMS to default injury and fatality fields to zero rather than null. A zero is valid data. A null is a compliance failure. This is usually a configuration change, not a training change.
Fire Module: Lock Incomplete Records
Fire incidents where the fire module is incomplete should be flagged in your RMS and assigned to the incident commander for completion within 24–48 hours. Don't allow fire incidents to go to "closed" status without fire module completion.
