DNP 805 Topic 4: structured vs unstructured data

Explain is the graded word. Sorting your fields into two columns takes a minute; saying what the database can and cannot do with each is the part that demonstrates you understand why the distinction exists.

The classification is only interesting if your list has both

This post inherits its content from the previous one, so start by restating the population and the element list briefly — a reader picking this up cold cannot follow a classification of fields they have never seen. Then be precise about what the two categories mean, because the common misreading is that structured means important and unstructured means optional. Structured data lives in a defined field with a constrained set of possible values: a coded diagnosis, a numeric laboratory result, a timestamp, a checkbox. It can be queried, counted, trended and joined without any further processing. Unstructured data is free text, dictated notes, scanned documents and images. It carries most of the clinical reasoning in a record and a database cannot act on it directly, which is the whole point of the distinction. Both categories matter clinically; only one of them can be counted without further work.

Explain is where the marks are, so give each classification a consequence. A structured Braden score lets you compute the proportion of at-risk patients who received a turning schedule; the wound description in the nursing note tells you what the tissue actually looked like and cannot be counted without natural language processing or a human re-reading it. Say what that costs — either you fund the processing, you re-key the data, or you accept that the field exists for humans rather than for analysis. A strong post also notices the semi-structured middle: a template with free-text boxes inside it, or a coded field with an unconstrained other option that quietly becomes the most-used value. Those hybrids are where most real clinical databases live, and naming one shows you have looked at a record rather than at a textbook definition. Naming one hybrid is usually enough to show you have looked at a real record rather than a diagram.

Likely learning objectives

Inferred from the brief — check these against your own rubric.

  • 01
    Define structured and unstructured data by queryability rather than by importance.
  • 02
    Classify real clinical elements and state the consequence of each classification.
  • 03
    Recognise semi-structured hybrids in real clinical records.
  • 04
    Identify the cost of making free text analysable.

Course-wide instructions that accompany this question

Important information for writing discussion questions and participation Hi Class, Please read through the following information on writing a Discussion question response and participation posts. Contact me if you have any questions. Important information on Writing a Discussion Question Your response needs to be a minimum of 150 words (not including your list of references) There needs to be at least TWO references with ONE being a peer reviewed professional journal article. Include in-text citations in your response Do not include quotes—instead summarize and paraphrase the information Follow APA-7th edition Points will be deducted if the above is not followed Participation –replies to your classmates or instructor A minimum of 6 responses per week, on at least 3 days of the week. Each response needs at least ONE reference with citations—best if it is a peer reviewed journal article Each response needs to be at least 75 words in length (does not include your list of references) Responses need to be substantive by bringing information to the discussion or further enhance the discussion. Responses of “I agree” or “great post” does not count for the word count. Follow APA 7th edition Points will be deducted if the above is not followed Remember to use and follow APA-7th edition for all weekly assignments, discussion questions, and participation points. Here are some helpful links Student paper example Citing Sources The Writing Center is a great resource Welcome to class Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires a lot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to. I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you. Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted. If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations. Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements. Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week. I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!

Review before submission

Common mistakes

  • Treating structured as a synonym for important.
  • Providing a sorted list with no explanation attached.
  • Assuming the reader remembers your previous post.
  • Ignoring the cost of processing free text into something queryable.
  • Missing the free-text 'other' option inside an otherwise coded field.

Submission checklist

  • Could a reader who missed your earlier post follow this one?
  • Does every classification carry a consequence?
  • Have you named at least one hybrid or semi-structured element?
  • Is the cost of using unstructured data stated?
  • Is the definition about queryability rather than value?
