Tips from a Road Warrior (17): Checklists are Critical!

I have been burned several times upon returning from a flight by either not being able to find where I parked my car, or finding it with a dead battery. The airport I fly out the most is DFW in Dallas-Fort Worth, which is very spread out and has five different terminals. It seems that every time I fly out of, let's say terminal C, I seem to return to any terminal but terminal C. I have come back at the height of summer, hauling two suitcases in more than 100-degree heat through the parking garage trying to find my car. I ended up getting a taxi to drive me around to find it.

On another occasion, I returned to a car without a battery as I left my interior light on. In this particular case, I was at a remote parking lot at JFK airport in New York City trying to call AAA road side assistance and could not convey to the person on the phone my car’s location, I fortunately ran into someone with jumper cables who could get me started. Having learned my lessons, I now have a "system" by which I always write down my parking space, and always check the car before I leave it at the garage for any lights etc. that might drain the battery.

Having a well-defined system for documenting status and locations really helps, not only when traveling but also when dealing with complicated systems such as healthcare IT systems, especially when multiple people are involved. I find that the institutions that have a very well defined checklist seem to have the least down time and fewest problems.

One of the hospitals I deal with has three shifts for their PACS administrators so they can provide 24/7 support on-site. There are always two or three people available, and at night typically one person. Needless to say this is a very large institution, which has a very high degree of availability of its PACS system. They have not had any considerable downtime in more than a year. In addition to having a robust and mature PACS system, I find that the main reason is the way that the PACS team monitors their system. They have a detailed checklist that helps them to regularly monitor all critical processes. Some of these are checked hourly such as the RIS feeds while others such as queues in the database or archive, as well as error files, are checked every four hours or as needed.

Some of the checking can be conducted by active monitoring software, which will page or e-mail an administrator that a process is going down, however, performance and intermittent issues are hard to detect automatically and require that someone has the finger on the pulse on a regular basis.

Checking a system on a regular basis and making sure that all errors and problems are addressed immediately as they occur will not only pay off in the short term, but also in the long term, especially when the data has to be migrated. When changing vendors, it is not uncommon that all of the information from the database and archive has to be migrated to a new vendor’s platform and, at that time, information that was mismatched, unidentified or incorrectly identified will rise to the surface. Upon migration, it will become obvious how well the system was managed during the lifetime of the system.

I learned my lesson when traveling by carefully documenting where I left off so I can get back on the road upon my return. For me, documenting is a necessity when dealing with multiple airports, parking garages, hotels, and facilities I visit. The same applies when managing complex systems: the better the documentation, the better the hand-off and ultimate quality of the information that is managed.
