Los Angeles City Fire Chief Brian Cummings acknowledged on Tuesday flaws in response data released by the department, but said fixes to improve accuracy are being put in place.

The conclusions and recommendations are contained in a report by the Task Force on Information and Data Analysis that Cummings presented to the Fire Commission at its regular meeting Tuesday. The content of the report became public last week after it was posted on the fire department's website.

Response times flared as an issue after the Los Angeles City Council in 2011 approved cost-cutting cutbacks to the fire department based on assurances response times would not be affected. Later studies brought into question the accuracy of the fire department's reports.

Response times are not generated directly by dispatch computer system, but have to be extracted through an analytic process.

It turned out the department was relying on inaccurate analyses and, in some cases, projections that tended to portray department response times faster than in reality.

The new study did not attempt to determine the extent of the previous inaccuracies, but found systemic errors and shortcomings in training that mean the previous analyses are unreliable, according to the findings.
