Which HIPAA considers as non-PII. We split the second group into two extra separate groups:

Which HIPAA considers as non-PII. We split the second group into two extra separate groups: (2A) ages which are described as entire numbers, which we annotate with label EW, and (2B) ages which might be mentioned as fractions of entire years (e.g., four and 1112 month ), which we annotate with label . Without the need of an anchor to a fixed date is not quite valuable to re-identify the patient; hence, it ought to be viewed as as non-PII. Nevertheless, it’s doable that a de-identification method could miss a mention in the report date, which, in addition to the age information in fractions (e.g., 11 months old in two days ), a single can be in a position to identifythe birth date of your patient. In other words, label AgeFraction could pose privacy threat only in conjunction with an inadvertently revealed full-date within the text. In the event the pati that re90 or older and annotate the earlier age references (i.e., 75 in the example above) as 75, he had an W as well.We do not annotate other age varieties which include gestational age, bone age (unless identical to the chronological age), school grade level (10th grade) or age periods like teenage, middle-aged, and so forth., considering that they are not as identifying as chronological age found in formal records. (e.g., The category Date comprises six labels: z (e.g., 2001), D (e.g., September), (e.g., 11th), K t Tuesday but not Tuesdays), ^ (e.g., 911, Hurricane Sandy, Katrina, Cinco de Mayo, New Year), and W (e.g., flu season, Monsoon, Ramadan, winter, second trimester). We annotate not simply those unique days which can be fixed in history like Pearl Harbor, 2008 Market place Crash but also those special days that occur each and every year for instance New Year, whose precise dates could be construed when combined with year data, which taken alone is just not PII beneath HIPAA. We also label personal special days which include birthday or Bar Mitzvah, not just resulting from possible privacy concerns as they might be out there from external sources, but also as a consequence of their prospective importance in reference to other events in the narrative text. We make use of the label W to annotate any time period longer than a day of which start and finish dates are not explicitly stated. We use this label to annotate periods like pregnancy, puberty, hospitalization period, and menstruation too as calendar periods such as early 2001 or within the 90s. Most age references in the healthcare history are periods. One example is, 5 years or five 5 years . Note e but if such age references previously reveal that the patient current age is 90 or older, we would must use label W rather. If a period of two days or longer is described in terms of an interval or perhaps a range with explicit start and finish date identifiers (e.g., 1995 97, involving next Tuesday and Friday), we separately annotate begin and end points with all the acceptable date label EW and 97 with W. Recall that we define the Period as a subcategory of date; hence, we use it only when the period could be stated relative to a date. In example, when the patient was 5 years old , we perceive a period of a single year, beginning five years following the birth date. If the period is stated using terms like last year, last month, final week, and final weekend, the period is defined relative to the date in the report. We do PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21310317 not annotate (therefore usually do not use the label Period) cyclical PQR620 chemical information temporal references such as daily, Tuesdays or just about every Tuesday or other temporal references described in sequence of events completed 2 weeks of antibiotics ). We annotate last Christmas or Christmas final year as ^ because the.
