There was an article in one of the recent issues of CF Roundtable about the CF Rankings and the differences between clinics and the fact that the ranks are not made public. There are some things you can do that can help you be informed. You can ask very specific questions of your current or potential clinic and other clinics in the area or around the country. Some good questions would be:1) How many adults (or children) with CF are seen at this clinic?2) How many years have the CF Specialists been practicing in CF each?3) In X situation, what is the standard protocol?4) How often are the patients seen routinely?Any other questions that are specific that can be compared to the answers of any other clinic you call are helpful. You may find that one clinic has two young doctors that have only been CF specialists for a few years each, while another may only have one specialist, but he's been there for 20 years. You can also ask under whom the specialists were fellowed. You can interview the doc(s) and ask how he differs in his views or approach from the docs under whom he fellowed. You can also compare standard approaches to different situations to see what fits your needs best. A clinic may or may not be able to give you a life expectancy age, but if they can it is good information, but needs to be weighed carefully with the population they are serving. One clinic may have a lower age, but may serve a poorer area and thus have people with fewer resources to care for themselves than another clinic with a higher age. Also, if the clinic is a bigger, better one they may serve people with more severe cases that some of the smaller satellite clinics feel capable to handle. That is one reason why the rankings are not publicized, because the mitigating factors are so complicated. You can still shop around. Just because you start being seen at one clinic, doesn't mean that after a few appointments or a hospitalization or at any point really, you can't transfer your care if you are dissatisfied.Depending on your point of view and needs, you may also consider having a family practitioner or pediatrician as the primary doctor and seeing a CF specialist just for CF care. Many people with CF end up just seeing the CF doc as primary and depending on the situation it may or may not be the best option.
