Selecting the Most Recent Case Data
Locked
 
|
I have a data set, which is derived from a commercial database on which clinicians enter information at patient intake and every three months thereafter until discharge. The administration number (1st administration, 2nd administration, etc. are numbered.) However, due to patient ‘no shows’, cancellations, and/or clinician error, some of the administrations are not included in a download from the commercial data base. The total number of possible administrations is 40. When I import into SPSS some of the admission numbers may be missing for all patients, resulting in a situation like the one below in which there is no data for Time 2, Time 4, or Time 5. However, there may be some data for those administration times the next import from the database. I’m trying to write syntax which will locate the first (initial) scale scores and the most recent scale scores, and at the same time allow for the fact that some of the administration times will be missing for some imports and not for others. I’ve tried vectoring, using do if’s and so on, pretty much exhausting my understanding of the FM. Any time a variable is mentioned, e.g. Date2 or 4 or 5 in the example below, the syntax stops. If the data below are like what I need to deal with, and the second set is what I want to end up with, how might I get there without having to write syntax for each download?

Ok, so I assume that repeated downloads are cumulative in that each download includes all records in the database at that time, even if a given record has been downloaded multiple times. The other thing I assume is that each record is a transaction: patientid, date, school, home, etc. The data organization is long format, not wide format. Let's also assume that data values once entered are not subject to future editing.
If you stack the downloads, you have multiple copies of some transactions and one copy of others. The problem is to get rid of duplicates and there is an Identify Duplicates function in the data dropdown, data window. Or, you could write your own. If the data comes out in wide format, then that is just an intervening varstocases command transform. Long format gives more flexibility for this problem, I think.

I had a situation somewhat situation to yours where
I was dealing with drug test results from weekly urine samples. In the context of the research intervention I was involved in, we would use the first week of participation in the research as "week1" and continue for a year to "week52". I created a vector week1 to week52 for weekly test results even though few if any participants had the full 52 weeks. Some skipped a week, some skipped months, some just stopped after a while (some of participants wound up in jail which made data collection, uh, difficult). Regardless of which weeks were missing, we wanted to see if the number of negative drug results increased over time, presumably as a result of the treatment intervention. Working with different vectors of 52 vars for different drug test results was fairly easy once the data was placed in the appropriate week in the appropriate 52 week vector. From the first set of numbers you provide below, it looks like you have not set up a 40 administration date vector, instead you only have variables for the administration dates that you apparently already have. Is this correct? If it is, I can understand why vectors would fail. For the data you have below you really should have six dates (date1 to date6) even though date2, date4, date5, are currently empty. Presumably, those dates will be filled in when new data come in. So it seems to me that you want three vectors: date1 to date 40, home1 to home40, and school1 to school40. This should allow you to do all of the analyses you want (i.e., first date, last date, number of missing dates, etc.). Does this make any sense to you? -Mike Palij New York University [hidden email] ----- Original Message ----- From: "Brian Dates" <[hidden email]> To: <[hidden email]> Sent: Tuesday, October 25, 2016 3:56 PM Subject: Selecting the Most Recent Case Data I have a data set, which is derived from a commercial database on which clinicians enter information at patient intake and every three months thereafter until discharge.

First create a dummy dataset with DATE1 TO Date40, School1 TO School40, Home1 TO Home40 then ADD it to real data. I would then splatter it with VARSTOCASES then use MATCH FILES with FIRST and LAST functions, SELECT the FIRST and LAST and then use CASESTOVARS. /* Untested code follows */. MATRIX. SAVE MAKE(1,120,-999) / OUTFILE * / VARIABLES DATE1 TO Date40 School1 TO School40 Home1 TO Home40 . END MATRIX. COMPUTE PatientID =-99999999. DATASET NAME FakeData. GET FILE <real data>. DATASET NAME RealData. ADD FILES / FILE FakeData / FILE RealData . SELECT IF PatientID NE -99999999. VARSTOCASES /MAKE Date FROM DATE1 TO Date40 /MAKE School FROM School1 TO School40 /MAKE Home FROM Home1 TO Home40. MATCH FILES FILE * / FIRST=FirstDate / LAST=LastDate / BY PatientID . SELECT IF FirstDate OR LastDate . EXECUTE. DELETE VARIABLES FirstDate LastDate . CASESTOVARS/ID=PatientID . HTH, David

Nicely done. The only difficulty that I see is whether
the new data received doesn't have anything "funny" about it. In the situation I described, the lab that did the drug testing was pretty good at providing structured data, so it was important to get the start date correct, create the new vector and then either match to an existing case or create a new case. It would be nice, however, if the OP would let us know whether our suggestions are on point or not (what is frustrating about some posters asking advice is that they provide too little information at first possibly because they think details are not important or don't want to provide too much info about their data for whatever reason). It's hard to tell if one is on the right track without feedback. -Mike Palij New York University [hidden email] P.S.
