General Comments about the 'System'



About the “Shotgun” Questionnaire

This template is adapted from a hypothesis-generating questionnaire developed in Oregon. It was designed for use when subtyping information (e.g., serotype or PFGE patterns) suggests a common-source outbreak caused by a widely distributed but unknown food item. It pretty much assumes that by the distribution of cases you have already ruled out attendance at a common event or location. Interviews will typically take 30–60 minutes depending on how chatty everyone is and how much detail you try to capture about foods that are named.

Food exposure frequencies for cases can be compared with specific controls or with known or estimated food consumption frequencies for comparable populations (e.g., FoodNet population survey information available at ).

Before deploying your questionnaire, decide on the time interval to be covered in the interview (e.g., 5 or 7 days before onset). The default is 7 days, which is reasonable for salmonellosis and E. coli O157 at least. Before you start, use a calendar to try and fix the starting and ending dates in the subject’s mind. Periodically remind the interviewee of the reference period. “Again, still just talking about those 7 days before you got sick, did you eat any....”

There is space left throughout the questionnaire to allow one to write in details about items of interest: brand names, whether eaten raw or cooked, purchase locations and dates, etc. Where an item lists several varieties (e.g., “clams, mussels, scallops”, check the 1 box and circle the specific choices if given (or write in). In the short term these details are rarely keypunched unless they are of special interest. How much detail is captured “up front” sort of depends on what stage of the investigation you are at and how likely you are to be able to easily re-contact the individual if necessary. Always notify interviewees that someone may need to contact them again to get additional details. Emphasize how much we appreciate their help in preventing other people from getting sick. One can of course attach additional pages of notes.

This questionnaire is inappropriate (or, at least, needs to be customized) for some kinds of outbreaks. Demographic clues (e.g., atypical distributions of age, sex, race, or ethnicity) may suggest a need to modify or abandon this very broad brush survey. Do not use it without thinking about what you are doing. Modify it as necessary—ideally in coordination with other users for a given outbreak! Familiarize yourself with the flow of the questionnaire before you use it. If you have time, it is a good idea to practice on a friend or family member that you don’t live with.

In a perfect world, a single person would do all interviews for a given cluster. This allows one to read between the lines and adapt a bit on the fly. Life is often not perfect, however; do the best you can.

Questionnaires should be faxed to a central location for keypunching; put the fax number in the footer.

Although it can be used as a stand-alone form, this template has been specifically formatted to facilitate rapid and accurate data entry into pre-existing FileMaker database templates and rapid analysis using customized EpiInfo 6 routines. For more information about these advanced features, refer to Oregon’s web site () or contact Bill Keene at the Oregon Public Health Division: 971.673.1111 or keene@). Do not delete the keypunch code letters (A B C D…) and numbers ( [1], [2], …).

We recommend that all finalized questionnaires be converted to PDFs before distribution; this is the best way to ensure consistent formatting between users with different systems, fonts, etc., and it keeps most people from messing with it (inadvertently, of course). It should be obvious that one should not change keypunching codes in the middle of the stream. Add additional pages and item blocks as needed at the end; do not insert new items into existing blocks.

As the investigtion progresses, you may be able to shorten the questionnaire. For example, you might drop items that none of the first 10 people mention; that may be 80% or more—a real time saver. There is a right way and a wrong way to do this. The easiest and best way to do this is not to delete the items per se, but rather change the color of the text to white. This makes the items “invisible” and preserves the order and consistency of the all-important keypunch codes. Once you color one item white, you can use the control-Y shortcut (command-Y on a Mac) to quickly repeat this action on subsequent selections. This does leave a bit of a Swiss cheese appearance to the questionnaire, but it is quick and allows one to easily go back if necessary.

Get precise answers for onset times if at all possible. Without a date and time, it’s hard to make a decent epi curve or to calculate incubation times. Estimates are OK. Prompt as needed: "What is your best guess of the time?" Don’t let them get away with vague stuff like “morning” or “some time after midnight.” Be careful with times such as "midnight" or early morning hours—which day do they mean? By “2 am Friday night,” for example, do they really mean Saturday morning? Keep probing until it is unambiguous.—and then write down what they mean—not just what they say. Midnight will be considered as the end of the day (e.g., 11:59 pm).

List by name any other restaurants that you can recall eating at that week; if possible what was eaten.

Now I’d like to ask you about a long list of food items, and for each one my question will be “Did you eat it in that same 7- day period before you got sick?” The lists are organized into categories, like eggs and dairy foods, vegetables and fruits, and so on. For each item, give me a “yes” or “no” if you remember eating or even tasting it in those 7 days before you got sick. Some of the questions might seem a little repetitive, but please try and answer each question individually, even if you think it was already covered. Unless I specify otherwise, I’m interested in whether you ate these items at home or away from home—either one, OK?

Believe it or not, that’s the end of the questionnaire. Thank you very much for your time. These interviews are extremely valuable in helping us solve the mystery of why people are getting sick. Depending on what we find out when we put these interviews together, we may need to follow up about a few details. Are there any other numbers I should have in case I need to reach you quickly?
