Database: changed field _action in table prescribed_medications to Integer to allow for negative values because remove action is coded as -1.
Database: Added a log table.
section_nurse.asp: Logs errors to the database.
section_murse.asp: Deletes all visit information for visits equal or larger than the current before inserting the current visit information.
APRN: Navigation buttons are disabled when contacting server and enabled again when server replies either with success or failure. Users can now move on to the next section or return and try again.

"Remaining Fixes Needed for PEP-NG April 20,2006" document released by Pat Neafsey. Above fixes follow this document.

List Component: changed colors for rollover and selection. (06-04-03)
Server: Page to see which medications a patient took on a certain visit
Meds: send info to server and store it in the database.
APRN: Put the dropdown words in bold - the way the drug names appear. (06-01-24)
APRN: added an “other” option and option to type in name.
Changed medication group start questions to:
1. Did you take something for a cold or sinusitis in the past month?
2. Did you take something for allergies or asthma in the past month?
3. Did you take something to help you sleep in the past month?
4. Did you take something for your stomach or for indigestion or gas in the past month?
5. Did you take any vitamins, minerals, herbs, or other supplements in the past month?
Education: changed the information and animations.
Tutorial: changed the medication list to use the pain relievers.
Tutorial: changed question to "Did you take an aspirin this week?"
Meds: navigation bug
Meds: sinusitis -> sinus
load_meds.asp: update query to remove multiple entries when a medication has several categories
Meds: The first item on the nested children should be regular strength (or parent)
SE: Change to "Touch the box that shows how sure you are about this". (06-02-14)
SE: Remove the text "each statement". (06-02-14)
Education: changed wording of medicine conflich screens to be more patient oriented and easier to read, less technical, according to Zoe's suggestions of text.
Calcium list-clock
Education: When program is “analyzing” change wording to “Please wait while we record your answers.”
IMPORTANT: Per the original survey, now need the questions/clock on:
1. Did you take something for a cold or sinusitis in the past month?
2. Did you take something for allergies or asthma in the past month?
3. Did you take something to help you sleep in the past month?
4. Did you take something for your stomach or for indigestion or gas in the past month?
IMPORTANT: Because focus group participants and first think aloud (key informants) got confused re Vitamin E and zinc whether they should list all their supplements, we need to remove all of the specific questions about Vitamin E, Zinc, Gingko, Niacin and simply ask 1 question that says (older: Combine non-alcohol choices for substances (gingko, etc.) onto one screen). (Put after the calcium question.) We can get the dosages by having the different strengths listed in the nested children.
Meds Section: Remove button to remove meds added by mistake. (05-12-05)
Self-Helath: [z—add “Internet” in a box in bottom row next to 800#]
Network: improved client and medication loading.

Self-health: Change to "How do you find out if a medication you buy over the counter is safe for you to take?". (06-02-14)
Self-health: Add "if none, click next". (06-02-14)

For the screen: "How do you find if an over-the-counter (non-prescription) medication is safe to take with your prescriptions or alcohol?" (Check all that apply). (05-10-1)
- Here we probably need a box that says "None." Some patients may never have thought to ask, or seek out, information about possible interactions, and we would want to know that rather than having them select something they haven't actually ever done. Tuck it in next to the long box at bottom.
Finding information on non-prescription: change text to “How do you find out what is safe to take with your prescription medications or alcohol?” (05-12-5)

Change to “Where do you usually buy medicines that do not need a prescription (including vitamins and herbs)?”.
Intro screens for each section. (05-10-1)

Screen with “Years of High School”

~~Show a list of the medications already inputed into the system. (05-10-26)~~ (05-11-15)
~~Add I don't know button to letter scale. (05-10-9)~~ (05-11-15)
Remove questions about “I drank more than I intended to”, from this section and add a short measurement scale for alcohol use. Move this alcohol scale to immediately after the earlier query, “Did you drink wine, beer, or liquor during the past month?” add Yes_ No_ “I never drink” and only give scale if participant answers Yes or No. (No during past month is not the same as never drinking).# ~~Large scrollbar in list component~~ (05-11-15)

Remove questions about "I drank more than I intended to", from this section and add a short measurement scale for alcohol use. Move this alcohol scale to immediately after the earlier query, "Did you drink wine, beer, or liquor during the past month?" add Yes_ No_ "I never drink" and only give scale if participant answers Yes or No. (No during past month is not the same as never drinking). I AGREE. LET'S TREAT ALCOHOL AS WE DO OTHER SUBSTANCES. THIS WAS THE SHORT 2-ITEM CONJOINT SCREEN FOR HEAVY ALCOHOL USE. WITH THE CLOCK IDEA, WE WILL GET A BETTER VIEW OF HOW MUCH AND HOW OFTEN THEY DRINK. FOR THIS CLOCK CAN WE HAVE A WINE GLASS APPEAR? (AND 2-4 AT A TIME SHOWN IF THEY CLICK REPEATEDLY?) (05-11-15)

~~Self efficacy instruction should be "Touch the box that shows how sure you are about each statement." (05-09-21)~~ (05-10-10 v.0.15 ß)
~~Transition page: "You have completed this section." (05-10-1)~~ (05-10-10 v.0.15 ß)
- ~~Here the centered type is awkward. I think we should make these statements flush left, ragged right and with shorter line lengths (see not below).~~ (05-10-10 v.0.15 ß)
- ~~Also, the second sentence seems like it can be eliminated to simplify. The other sentences make sense without it.~~ (05-10-10 v.0.15 ß)
~~Change the sample intervention question on thyroid pills and calcium:~~
1. Change the answer that says “2 hours after her other medicines” to “4 hours…”. The animation stresses that for thyroid meds, one needs to space calcium and other minerals by 4 hours. (With other meds it is 2 hours). (05-09-22) (05-09-22 v.0.14 ß)
2. ~~Change the “YES…” to “YES, waiting at least 4 hours will not affect the absorption of her thyroid medicine.” (05-09-22)~~ (05-09-22 v.0.14 ß)

Education: screenshots of animations to connect to education points. (2006-04-20 Pat Doc)
APRN: Medication Input Screen
1. Fix dropdown boxes button - see Skinning (06-01-24)
  - The button's size is wrong and has to do with the tailoring of the medication list scrollbar. Need to go over each component and figure how to tailor each independently. It might require coding subclasses of each component.
2. Have the dropdown boxes transform into textfields when use chooses other. (06-01-24)
Printout: screenshots of animations to connect to education points. (2006-04-20 Pat Doc)
Printout: Printout for controls should list meds, symptoms that patients report. (2006-04-20 Pat Doc)

Sort the children medication list based on the sort order from the database.
Make AM, PM, midnight and noon change color when the hour is selected.

Interface Components

Enhanced List Component
a list that scrolls one page at a time.
- might be better if one can set the amount that is scrolled
should also allow one to set the width of the scrollbat

The list page is something of an unknown right now. Users have demonstrated they would prefer that in previous focus group but I would like to see them try it. If indeed that's the way to go then it will take some time to implement that because it requires meddling/tweaking a component that is deeper into the system. Possible, yes. I have put a lot of hours trying to get it done and could not do it, I know the direction of the solution but it will take some time to get there. What you see today in the first list of the first medication input screen (antihypertensives?) is just a rig that I did. One option is to use the rig in all lists, the end user might not even notice the difference, but it is a shortcut now for work that will have to be done later at some point.

Skinning

List component: make actual scrollbar wider
ComboBox: scrolbar in the dropdown list should be thin The problem is that it is getting the size from the list scrollbar. Might require coding a new list component with adjustable scrollbar width (06-1-9)

Internal

Redo DEBUG_noserver variables. (05-11-10)
Sections Framework
1. Section class. (05-12-01)
2. Recode section flow. (6-1-24)

Interaction Server

Recode for to check the amount of medication in units of the medication instead of units taken.
What to do with "as needed"? (2006-05-20)

load_meds.asp

Also load the medications whose children are of the specified categories
Use parent-child relational table
Load the children sort order too.
1. Sort children by sort number and then name

Medication Database

Restructure to have a relationship table for parent-child medication
- This is needed because the load_meds.asp script needs to choose the parents that have certain medications as children. The way it is now, we can only get the children that have a certain parent.
Fill out all doses and unit fields
Add a sort order field to the children so that we can define the order that they appear on the list.

Medication Database Management WebApp

Store date_created when inserting ingredient categories. (06-03-07)
Store date_modified when updating ingredient categories. (06-03-07)
Page to dump the medication database out to a csv file. (06-03-04)

PEP-NG Documentation

Client Documentation

Users will have a notepad to write down meds that they don't find in the list and the APRN will email those meds to us. (2006-04-20 Pat Doc)

Patients are allowed to skip questions because they have the right not to provide information - this was decided with Pat on a meeting around April 20, 2006 (2006-05-02).
