• Requires the collection, analysis, and interpretation of data to define the problem and outline:
– What
– Where
– When
– Who
– How

• Requires a determination of:
–Preventable or not preventable
–Controllable or not controllable
–Priority

• The potential for prevention or control frequently requires:– A plan – A champion– A strategy/method– A method– The will– Funding

• After implementation the cycle begins again, but this time to evaluate the program results.– Did the strategy work as intended?– Were the results as expected?– If yes, can you expand or replicate
the program?– If no, do you abandon or revise and
try again?

• The data outlines the problem to be:
–A barrier problem (none, failed or inadequate)
–Supervision failure

• Is the problem preventable or not preventable?
–The problem was considered preventable.
• What was the priority?– High

• The Goal!
–One of the health objectives targeted in Arizona 2000 was to decrease the death rate for drowning to 1.3/100,000. The 1996 drowning rate for Arizona residents of all ages exceeded the target rate by 69 percent.

• The response by the ADHS, DPCCA, CDC, ARC, and others was to:– Seek legislative action
– Develop community educational program
– Develop an individual pool safety program

• Results:– The legislature passed a bill in 1991
requiring fencing and buyer notification (A.R.S. §36-1681)
–The education programs were developed and implemented by realtors and volunteer groups

• It worked!
–Drowning mortality rates dropped
• Year Rate/100.000
• 1974 21.3
• 1981 19.5
• 1989 11.9
• 1990 5.8

• Of 269 drownings from 1995 to 2001, only six occurred in pools that were fenced and had properly latching gates.

• It was better, but it didn’t last– Drowning mortality rates began increasing
• Year Rate/100.000• 1991 8.5• 1992 7.1• 1994 8.0• 1995 9.9• 1996 8.5

• What happened?
• We have to return to data collection and analysis to seek the answers

• The findings show:
– Failure to use or maintain barriers
– Failure to supervise
– Parental inattention
– No requirement for interior pools
– Not all drowning occur in swimming pools

• In addition:
– The statute allowed cities and counties to pass their own ordinances provided they were equal to or more stringent that the state statute, which lead to some confusion.
– The need for a statewide standard.
