Real Life • How many of you have experienced cooling system failures? – Sudden – Compressor – Thermostat of Refrigerator/Freezer • Power Failures? – 2 this season on the Central Coast • Human Error? – System unplugged – Manual Recording takes dedication 42 nd NIC Conference March 2008 2

Stand Alone Manual Systems 42 nd NIC Conference March 2008 3

We can do better… • • • Because staff turn off alarms Alarms are not set appropriately Alarm units become unplugged Temperatures are not recorded correctly • Only effective 24% of the time – during normal working hours 42 nd NIC Conference March 2008 4

Cost Effectiveness • Automated systems range from a one time cost of $740 (phone line tech) to $1, 300 for a two sensor probe system per site. • Annual fees, usually after one or two years depend on data storage choice and need of support est. $10 /site/mo. • Cost of vaccine for a PHD site that averages 80 child and 50 adult shots per month …. 42 nd NIC Conference March 2008 5

$36, 813 (VFC $24, 249 Private $12, 564) At any single point in time. 42 nd NIC Conference March 2008 6

Advantages of Automated Temp • Monitoring – Any number of people can monitor from their computer at work, lucky “few” can also from home. (or with desktop access anyone can monitor from off-site) – IZ Coordinator or supervisor can monitor refrig/freezer of closed clinics. – System monitors when people forget. – Frequency can range by company from 30 sec to 5 minutes. – Saves time from daily logging temps. – No guessing for time out-of-range. 42 nd NIC Conference March 2008 17

Advantages of Automated Temp • Reports and Data Storage – Stores data off site at company or secure data storage firm or in-house. – Data stored at least 10 years. – Reports can be generated from various parameters, site, unit, date, frequency. – Can individualize how often staff should print out reports. – USER FRIENDLY 42 nd NIC Conference March 2008 25

Other Considerations • Location of company, East or West Coast , if they do not have 24/7 live support • How readily is technical (not sales) support available? • How simple is the system to adjust and for staff to view and print reports? • How long has the company been in business and are they on the forefront of advances? • How easy is it to install (usually very easy) • Type of probe’s available (glycol or air)? 42 nd NIC Conference March 2008 30

More Other Considerations • Written instructions available? • Compare Reader vs Administrator access. • Is the transmitter inside or outside the refrig/freezer? (extra wires) • Are different alarm levels available? • Do alarms repeat? • Memory capability or battery backup needed? • White wine thermostats (45°-50°) vs Food (33°-38°) 42 nd NIC Conference March 2008 31
