Revisiting the Cantrell tragedy - Murphy 911 and emergency response times

Last month, there was renewed media interest in the sad death of a Murphy toddler. The child was strangled after being caught in a backyard soccer net in 2007.

After, WFAA and the Dallas Morning News wrote articles critical of the Murphy 9-1-1 operator and the Murphy police, the City released a report on the incident written by the then acting city Manager.

The news media focused on an emotionally charged 9-1-1 call by the child's distraught mother leading to a 2-1/2 minute delay in summoning the EMT's.

It seemed to me that the 6 minute police response and the 8 minute EMT response time after dispatch was unusually long for a city as small and compact as Murphy.

In order to try to obtain some basis for critiquing the emergency team's responses, I sent open record requests to both Murphy and the neighboring City of Wylie.

The results are sobering.

For the Murphy Police Department, the average response time (averaged over 15,530 calls in 2008) was almost 7 1/2 minutes. Most of that time - 4 1/2 minutes was spent before 9-1-1 actually issued a dispatch to the patrol officers.

However in Wylie, the average response time (averaged over 27,230 calls in 2008) was 4 3/4 minutes. The time 9-1-1 needed to dispatch averaged only about 1 minute.

The statistics for Fire/EMT response are just as disturbing.

In Murphy, the average response time for Fire/EMT was over 8 minutes. In neighboring Wylie, it was 4 1/4 minutes.

Benchmarks set by the National Fire Protection Association (Standard for the Organization and Deployment of Fire Suppression Operations, Emergency Medical Operations, and Special Operations to the Public by Career Fire Departments) call for a response time of 4 minutes or less, achieved 90% of the time.

Studies have proven that reduced response times save lives. One 10 year old study showed that reducing the EMT arrival time from 8 minutes to 5 minutes almost doubled the survival rate of patients in cardiac arrest.

Another study, from 2005, showed that while 8 minute response times did not positively impact survival rates, moving to the 4 minute average did have a significant effect on overall patient survivability.

The Wylie fire department has an ISO 1 rating, which is the highest rating offered by the Insurance Services Office, who rates fire departments on a scale of 1 (best) to 10 (worst). Murphy's ISO rating is 4.

Looking a little deeper into the sub-par Murphy statistics, I discovered 2 things that far outweigh the smaller size of Murphy's public safety departments.

First, in 2006, Murphy made a decision to bring 9-1-1 operations "in-house" as part of the police department's communications division. In 2007 (at the time of Matthew Cantrell's death) the authorized staffing for police communications was 5 persons. That was increased to 8 in 2008, but decreased to 7 in the 2009 budget.

Second, according to those I've talked to, the City Council stopped receiving regular response time statistics from the city manager "a few years ago".

It would appear to this writer that the city's slow response times are the result of management neglect, poor implementation of the 9-1-1 system, and by lack of oversight by the elected city council.

I have been told that the Murphy FD is now fully paid. I relied on old information from the City's web site.

I have removed the references to the Volunteer FD from the post, and I apologize for the inaccuracies.

A knowledgeable reader provided a good summary of the ISO rating system. His goal was to point out (rightly) that Murphy's lower rating had more to do with the availability of fire hydrants than with the preparedness of the department's personnel.

I want to emphasize that I am not casting aspersions on Murphy's public safety employees. Rather I place the blame for lower performance squarely where I believe it belongs - on management and on council oversight.

Here is the reader's description of the ISO rating as it applies to the Murphy Fire Department:

"Murphy's ISO rating is probably 10 years old. They did do an ISO study a year ago and it was determined, by the consultant, they could definitely move their ISO rating to 3 and possibly a 2, as the Department stood.

They lacked in some equipment and decided to hold off the expense of another ISO rating adventure until the equipment was secured. The last rating was done at a time when Murphy's water supply wasn't as efficient as it is today.

ISO rating is heavily dependent on water supply. The rating breakdown is:

- 10% Alarm and dispatch
- 26% Equipment
- 9% Training
- 15% Personnel
- 40% Water Supply

The rating uses a divergence factor when your fire department is effective but you don't have an adequate water supply. The divergence factor is utilized to as a means to reconcile the difference. The balance of 50% Fire Department (Equipment, Training, Personnel) and 40% Water Supply must be retained in the ISO rating. If a department gains 40 points in the Fire Department and 10 points in Water Supply the divergence factor is -11 points. The formula for divergence is:

Divergence = -0.5[|(Water Supply) - 0.8(Fire Department)|]

In the example I gave above, while the Fire Department received 40 total points for Fire Department and 10 points for Water Supply, only 39.0 points would be given for the combination of the two.

This is why adequate water supply is highly important.

I believe there are only 5 ISO 1 communities in Texas - Plano, Frisco, Wylie, Houston and Tomball. McKinney, for example, I believe is an ISO 4."
