- Applications Overview
- Summary
- Q & A

**Notes:**
Discuss BCRO statement:
In FY’06 there was no VA funding for required VistA interface development for Care Fusion’s BCE Applications. In January 2007, Veterans Administration Office of Information & Technology (VA OI&T) approved the necessary funds to move forward with these VistA interface development efforts. These VistA interfaces will be developed by VA OI&T in collaboration with CareFusion. The schedule to develop these interfaces to support CareFusion BCE Applications is being developed by VA OI&T at this time. 
In addition, VA OI&T has raised concerns regarding the ability of facility wireless networks to support additional wireless applications. Discussions with VA OI&T concerning facility level wireless network infrastructure have identified the need to create a wireless infrastructure standard within VHA that will support all wireless application deployments now and in the future. VA OI&T has conducted a wireless survey with facilities and is in the process of analyzing the results. VA OI&T has strongly advised that deployment of BCE be accomplished in tandem with the VA OI&T proposed wireless infrastructure upgrade schedule. Also, Care Fusion has received a 510K green light from the FDA to promote the BCE applications on a new device that will improve device compatibility with wireless infrastructure and bar code scannability for the end user. This new device is a Symbol MC-70. 
The above actions have created project delays. However, through these delays, opportunities have been identified that will enhance the development, deployment and support for BCE applications and improve the ability of Care Fusion’s BCE applications to meet the needs of the end user community. VA OI&T will be working with the BCE test sites regarding schedule changes once they are known. 
Your continued support for BCE is greatly appreciated as the project team continues to ensure these applications can be adequately supported within your wireless infrastructure and improve the ability of BCE to meet the business needs of the business community within VHA. 

## 	Project Overview

- National Center for Patient Safety Initiative
- Provide centralized approach to clinical barcode applications in VHA

**Notes:**
The initiative started in 2004. $25 million were allocated for the project.  It was to include funding for devices, servers to run proprietary software, vendor client software, vendor software installation, and vendor applications training. Servers and a limited number of PDA’s (Personal Digital assistants) with built-in bar code scanners were intended to be deployed to each inpatient facility.  Additional PDAs were meant to be purchased by the medical centers.
Although BCE started in 2004, almost three years passed until VA IT funding was allocated. National Center for Patient Safety actually proposed the initiative, but Patient Care Services managed the project once the NLB approved it.

## 	Why BCE?

- Patient misidentification
- Vulnerability in labeling
- Case in point
- Patient Safety Manager (PSM) reporting

**Notes:**
Patient misidentification is a persistent cause of adverse events in VHA facilities. These adverse events include wrong blood product transfusion, wrong medication administration, inaccurate admitting and record documentation, mislabeling of laboratory and blood specimens, and incorrect surgical procedures. Barcode wireless technology functionalities will improve the accuracy of patient identification at the episode of care and reduce the incidence of adverse events due to misidentification.
The 2003 review of the RCA database by the National Center for Patient Safety exposed vulnerability in labeling of blood samples, laboratory specimens and pathology slides. Mislabeling is more likely to occur if patients have similar names, if patients change bed or room assignments after the order for laboratory studies has been entered, or if multiple labels appear on one sheet for application by the nurse, phlebotomist, laboratory technician, or physician. These factors can result in a blood sample being drawn from the wrong patient, a blood sample or lab specimen labeled for the wrong patient, or the wrong blood product transfused. 

One of many examples in VHA facilities of patient misidentification due to mislabeling occurred in 2003.  Two patients (Patient X and Patient Y) with the same first and last names, but different middle initials, were inpatients in the same VA Health System, one in the acute care hospital and the other in the nursing home care unit.  Patient X was blood type O negative, and Patient Y was A positive.  A blood type and cross-match for transfusion of Patient X was ordered by his physician, and a type-and-screen was ordered for Patient Y by his nursing home provider.  Unfortunately, the blood specimen used for compatibility testing of Patient X was mistakenly drawn from Patient Y but labeled as Patient X.  As a result, Patient X was transfused with two units of A positive packed red blood cells, the wrong blood type for this patient.  Patient X sustained a transfusion reaction and expired two hours after the second unit transfusion had been completed.  With the clarity of hindsight, there were several missed opportunities for checking the proper identification of Patient Y; when his blood specimen was drawn by the phlebotomist, when the blood specimen was processed in the Blood Bank, and when his nurse administered A positive blood to Patient X.  However, the fact remains that current processes for laboratory and pathology specimen labeling are vulnerable to patient misidentification adverse events in all VAMCs.

Patient Safety Managers (PSMs) are receiving a steady stream of reports from Community Based Outpatient Clinics, inpatient units and emergency rooms of VA facilities raising persistent problems with laboratory specimen mislabeling. The traditional approach by PSMs in response to this problem has been “event reviews” with staff, but this approach has not reduced the incidence of these occurrences. PSMs are reporting to NCPS that “more effective barriers are needed” to solve the problem of mislabeling.

- Lab/Specimen Collection – wCareCollect
- Blood Administration – wBloodCare
- Medication Administration – wMA
- Vitals and Inputs/Outputs (I&O) – wCareAssist
- CPRS view only – wCareView
- Code Blue

## Applications Icons

- WCareCollect
- W Blood Care
- WMA
- WCareAssist
- WCareView
- Calculator

**Notes:**
This is a screen shot of the PDA applications.  As you can see it has all the icons that Jan just mentioned.  They include W CareCollect for Specimen Collection, WBlood Care for Blood Transfusion documentation, WMA for Medication Administration, WCareAssist for Vital Sign Entry and will soon include Intake and Output documentation and WCareView which is a read only version of CPRS.   I want to also point out that there is a functioning calculator.  Now that you know the applications currently available, let’s talk about the handheld PDA itself.

## Overview of the PDA

- Red power button
- Yellow scan buttons on each side
- Integrated scanner beams from the top
- Has a tethered stylus
- 4 function buttons that are assigned to different applications
- Home button that allows the user to navigate from application to application

**Notes:**
This is the PDA.  It weighs 12 ounces and measures approximately 6 inches by 3 inches.  It has a red power button on the front and 2 scanner buttons on each side.  You only have to depress one scanner button to activate the scanner.  The scanner light comes from the top of the scanner.  There are 4 function buttons on the front of the scanner which allows the user to navigate rapidly between applications.  The first button, which looks like a calendar, is assigned to WMA.  The second button is assigned to CareAssist, which is the vital sign entry application.   The third button, looks like a clipboard with a check, is assigned to CareView.  The fourth application button, which looks like a cassette tape, is assigned to Care Collect.  I also want to point out the “house” at the top of the screen.  This is another quick way that a user can navigate through applications.  Next to it is a battery level indicator.  These devices come with a long-life battery that provides up to six hours of continuous use.  The device is kept in a charger base when not in use.  The device will alert the user when the battery gets down to 30%.  Staff can also change out batteries in the middle of the application and it will not log the user out.  There is also an internal battery that will maintain the device and applications for 10 minutes.  

## wCareCollect (Lab Specimen Collection) 

- The printer attaches to the PDA for point of use printing

**Notes:**
The first application I would like to present is Care Collect.  This picture displays how the portable printer attaches to the PDA for point of contact printing.  The current process requires staff to print labels for individual patient’s which can easily get lost or for Lab Collect times the entire patient care unit is printed and up to 15 feet of labels will print out.  Another big problem with the current process is the nurse or phlebotomist is unable to update the list after printing and before venipuncture which ferquently leads to the patient getting re-stuck.  We have reviewed the physical characteristics of the scanner and the current process, let me demonstrate the CareCollect Application.

## wCareCollect (Lab Specimen Collection)

- Log in using your
-       VISTA/CPRS
-       Access Code

**Notes:**
This screen shows the log-in screen.  The access and verify codes staff use are their VISTA/CPRS codes.  After entering the codes, tap on “Enter”

## wCareCollect (Lab Specimen Collection)

- Scan the patient
-    Wristband
- Confirm patient
- Allergy Alert

**Notes:**
Once log in is complete it will bring you to this screen.  At this point, staff will scan the patient wristband to assure for accurate patient identification.  Then you will acknowledge a patient demographic screen and an allergy alert screen.

## wCareCollect (Lab Specimen Collection)

- It will bring up all ordered
- 	tests
- You can view collection details
- 	by tapping on the item
- Staff can view different
- 	collection types such as
- Active
- Lab
- Unit
- All

**Notes:**
After acknowledging the allergy screen this is the next screen.  Let me point out a few features of this screen.  Starting at the top you will see the USER name, which at this time is “Nurse, Two”.  Directly below that is the Patient name, which currently is “THREE, PATIENT” followed by their Social Security Number in parenthesis.  If the name and Social Security Number is too long and truncated off the screen, there will a sideways triangle indicating there is more information to be viewed.  This information can be viewed by tapping on the triangle.  Below the patient name there is a gray shaded box which is a key for the contents below.  For example the Sample ID will be the Accession Number, and the Tests will show what test is ordered.  It will also display what type container is required for that specimen.  If there are special “Collection Details” about a particular lab test, the user can tap on those words and it will display the details of the collection, such as, a timed test or fasting test.  At the bottom right of the screen you will see “Collection Type”.  Staff are able to view and print labels from each type of collection.  The different collection types are Active, Lab, Unit and All.  After reviewing the different specimens to collect the user will tap on “Labels” to print all the labels for the ordered specimens.  They will then proceed to obtaining the specimen via their facility policy and procedure.

## wCareCollect (Lab Specimen Collection)

- After obtaining the
- 	specimen and placing
-    	the labels on the tube,
- 	staff will scan the barcode
- 	to put an electronic
- 	date/time stamp and
- 	staff identification on
- 	that specimen

**Notes:**
After obtaining the specimen, staff will place the label on each specimen tube or container.  They will then scan each label to electronically place a date/time and staff initial who collected the specimen.  This is a major change for the inpatient process where currently the labels that print out for an inpatient are lab order numbers not accession numbers.  Then when received by the lab, a technician has to “receive” it in the lab package, print an accession label and re-label the tubes with the accession number.  The current process of re-labeling leads to increased workload for the lab personnel as well as increases the potential for labeling errors.  This is the basic process for specimen collection.  Now I would like to move on to Blood Transfusion documentation.

## wBloodCare (Wireless Blood Administration)

- The Process
- Scan patient and blood unit
- Record Vital Signs, presence of informed consent, documentation of reaction
- Coordinated with the VBECS package
- Will replace paper SF 518

**Notes:**
W BloodCare is the application staff will use to record Blood Transfusion information such as Product Number, Patient identification, Vital signs, 2nd verifier, presence of informed consent, documentation of transfusion reaction, etc.  This project is working in coordination with the VBECS (VISTA Blood Establishment Computer Software).  The final Blood Care document will be able to replace the paper SF-518.  Barcode scanning technology will be used to assure the correct unit of blood is administered to the correct patient.  Let’s review the process now.

## wBloodCare (Wireless Blood Administration)

- After logging in and
- 	scanning the patient
- 	barcode, you will see
- 	a listing of all available
- 	cross-matched units

**Notes:**
The log in process is the same for all applications.  After logging in and scanning the patient barcode, this screen will be displayed.  I would like to review this screen now.  At the top you will see the User: Nurse,Two.  The Patient:Three, Patient followed by the Social Security Number.  In the green shaded box, the patient blood type is displayed and if your site uses a Blood Bank Number that will be displayed here.  Below that in the gray box is the key to the blood product information such as Unit ID, Product Type, Release Date/Time, etc.  Only cross-matched units will appear on this list.  After obtaining the unit from the blood bank the first step in documenting is to scan the blood product.  Before picking up a unit of blood staff should make sure the patient wristband is scannable as this is an essential step in the process.  After scanning the unit, staff will be required to enter Vital signs as we will see on the next slide.

## wBloodCare (Wireless Blood Administration)

- Application allows
- 	user to enter vital signs
- 	per facility policy.
- These vitals are
- interfaced back to CPRS

**Notes:**
This is the screen that is used to enter vital signs.  The application allows the user to enter vital signs per individual facility policy.  These vitals are also downloaded into the Vitals Lite/VISTA/CPRS packages.  There is also the functionality to import vital signs that may have been taken by in the CareAssist package.  Let’s review this screen.  There is the ability to change the time the vital sign was obtained if necessary.  Remember these times are important as most transfusion medicine areas require blood to be started within 30 minutes of checking it out.  Temperature will be the first screen to come up and staff will enter the temperature and tap on “Next” .  Tapping on “Next” will bring up the subsequent screens such as Pulse, Blood Pressure, Respirations, etc.  The appplication also allows staff to enter the milliliters per hour the blood is infusing and if the patient is stable or unstable.  After saving this information by tapping on “save”.  It will then require log in by a second verifier as shown on the next slid

## wBloodCare (Wireless Blood Administration)

- Second verifier enters
- 	their access/verify
- 	code

**Notes:**
This slide shows a screen shot where after verification per facility policy the access and verify code of the witness will be entered.  The verifiction between what the blood caution tag, the blood unit and the data in the PDA handheld will be performed prior to the entrance of the witness verification.  Tap on “OK” to record the witness verifiction to continue with the blood transfusion documentation.

## wBloodCare (Wireless Blood Administration)

- Recording the start of the unit of blood

**Notes:**
This screen shows all information that can be reviewed if desired.  At this point staff would tap on “Begin” to record a time stamp for when the unit was started.  If desired the application can be closed until the next action is required per facility policy.

You can also enter vitals from this screen.  To do this you would tap “Vitals” at the bottom left of the screen and it will take you to the vitals entry screen or allow importing of vitals entered via CareAssist or from Vitals Lite.

Staff can exit the appliction and get back into this patient’s individual transfusion history as we will see on the next screen.

## wBloodCare (Wireless Blood Administration)

- Continuing the transfusion

**Notes:**
Staff can easily reenter the patient record by scanning the wristband in the WBloodCare Application.  It will then display this screen.  To get back into the unit that is transfusing, staff would tap on “Transfusion Activities” that is highlighted in blue.  

This will then take staff to the next screen where bital can be entered, Actions such as Completing or Stopping the transfusion can be recorded as seen on the next sceen.

## wBloodCare (Wireless Blood Administration)

- Further actions that can be taken:
- Enter additional vitals
- Complete the transfusion
- Stop the Transfusion

**Notes:**
This screen shows where staff can take several different actions.  They are able to Complete the Transaction, Stop the Transaction or Enter additional Vital Signs.

If the transaction is “Stopped” for any reason, a stop action is required to be entered from a drop down list as well as a stop reason.

When a transfusion is Completed or Stopped the amount transfused must be recorded which can be seen on the next screen.

## wBloodCare (Wireless Blood Administration)

- Record total amount
- 	of blood product
- 	infused

**Notes:**
Staff must enter the volume transfused on this screen.  Then tap “OK” to Record the transfusion.  This electronic documentation will be recorded as a progress note in CPRS.

This concludes the demonstration of WBlood Care.  Next I would like to demonstrate WMA (Wireless Medication Administration)

## WMA (Wireless Medication Administration)

- Takes BCMA software and reconfigured it to display on a PDA
- Is used currently at 18 VA’s
- Can be used as an adjunct to med carts with laptops or as the only device for medication passes

**Notes:**
WMA is the Carefusion application that takes BCMA software and reconfigures it to appear on the handheld PDA device.  It is currently installed and in use at 19 VA’s throughout the country.  It is typically used as an adjunct to wireless medication carts.  A  few VA’s are using the PDA as it’s primary medication administration documentation system.  It has also been found to be very useful for things like PRN and IV fluid documentatin.  Let’s review the application and you will quickly see the similarities and differences.

## WMA (Wireless Medication Administration)

- Similar functionality
- as BCMA
- 	Start/Stop time change
-   UD, IVP/IVPB, IV tabs
-   Rearrange Fields
- Medication, Admin
- Perform PRN effectiveness

**Notes:**
As in the previous application reviewed the top of the screen displays the User and Patient.  In WMA if the patient has an allergy on record a large red A will appear in the top right corner.

Going on you will see the start and End fields that have the drop down fields as in BCMA.

Staff can rearrange the fields like in BCMA by tapping on “Medication” and “Admin”.  The defaults set in BCMA are the ones that are used in WMA.

As in BCMA there are green dots to indicate if there are active orders in the UD, IVP/IVPB, or IV folders.  Staff can also select C for Continuous or On Call, PRN or One time orders.  If the field is grayed out, it indicates there are no active orders as in BCMA.  The one green dot that is not available currently in BCMA is the Cover Sheet.

Scanning of the medication is done with the same alerts as in BCMA.  A “G” for given will show in the Left column

PRN effectiveness can also be done by tapping on the words

## WMA (Wireless Medication Administration)

- Instead of menu bars at the top of the screen there is and “Action” menu at the bottom left

**Notes:**
Instead of menu bar in BCMA at the top of the screen, there is the “Action” button at the bottom left.  After tapping on this all the menus will be available per BCMA protocols.  Available menus will be in bold black lettering.  If an option is not available it will be grayed out.  

Now I would like to move on to the Care Assist application

## wCareAssist (Wireless Vitals/Inputs & Outputs)

- The Process
- This functionality will allow staff to either Enter vital signs manually or beam them over via an infrared beam
- The vitals recorded in the PDA will be stored into the appropriate VISTA file and be accessible in Vitals Lite and CPRS

**Notes:**
The wCareAssist application enables Nursing staff to enter vital signs on the PDA in a more efficient and accurate manner.  In many facilities there is a shortage of available computers and this allows all levels of nursing staff to abandon the pieces of paper and enter vital signs as they are obtained.  

Vital signs entered via the PDA are transmitted via the wireless network and stored in the appropriate VISTA file and is viewable in CPRS and Vitals Lite.

Let’s look at the actual process now.

## Retrieving Patient Records 
Scan the patient wristband
Acknowledge patient demographics
Tap on “OK” to proceed

- Scan the patient wristband
- Acknowledge patient demographics
- Tap on “OK” to proceed

- wCareAssist (Wireless Vitals/Inputs & Outputs)

**Notes:**
This screen prompts the user to scan the patient wristband.  There will be the Patient Demographic and Allergy Alert screen that follows.  

It is possible to pull up a patient via manual entry but it is discouraged due to patient safety issues.

The user then taps on OK to proceed to the next screen

## WCareAssist (Vital signs and Intake and Output)

- Vital Sign Entry Screen
- 		-Enter Vitals
- 		-Vitals Mark Errors
- 		-View Vitals
- 		-Dinamap
- 		-View Allergies

**Notes:**
This is the next screen that directs the user to vital sign entry.  There are several options available here.  Staff can enter vital manually, mark vital errors, view vitals and beam over vital signs from the Automated Blood Pressure machine.

Let’s first talk about entering vitals on the PDA.  The first step would be to tap on the “Enter Vitals” icon.  This would then bring you to the vitals entry screen

## WCareAssist (Vital signs and Intake and Output)

- Selection of Vitals

**Notes:**
Select the vital that you wish to record on by tapping on that one.  To demonstrate “Pulse” is selected.

## WCareAssist (Vital signs and Intake and Output)

- From the vitals entry screen, tap on the vital sign you want to record
- It will bring up this type of screen
- Enter the patient’s vitals
- You can record “qualifying information” in the drop down fields
- Tap on the Next or Prev. buttons, to repeat the steps for the remainder of vital signs
- You may also select “Unavailable” or “Refused”
- Tap on Summary and select “Save” to record vital signs in CPRS

**Notes:**
This is the vitals entry screen.  Vital signs are entered as appropriate.  Qualifying information can be added as defined by Vitals Lite.

If needed, Uanavailable or Refused can be selected if appropriate.

Tap on “Next” to go to the next vital or select Previous or Summary.  Summary will prompt the user to save the results

## Vital Sign entry via beaming over the vital sign from the automated blood pressure machine

- wCareAssist (Wireless Vitals/Inputs & Outputs)

**Notes:**
Next I would like to demonstrate an even faster way of vital sign entry.  This method uses infrared beam technology to transmit vital signs from the blood pressure machine into the CareAssist package.

On this screen, tap on “Dinamap”

## Beam over vital sign option

- wCareAssist (Wireless Vitals/Inputs & Outputs)

**Notes:**
This is the next screen that will appear.  On this screen staff will tap on “Update” and will hear a beeping from the PDA

The next screen will prompt the user to align the infrared port fount on the back of the PDA with the infrared beam on the automated blood pressure machine.

## Alignment of the infrared beam with the receiving port on the PDA

- wCareAssist (Wireless Vitals/Inputs & Outputs)

**Notes:**
As this screen indicates the PDA is aligned with the infrared port.  When the vital is accepted by the PDA an audible will alert the staff.  

Staff will then be prompted to Accept the result and it will be stored.

The last application I would like to cover is CareView.

## WCareView (Read only CPRS)

- The tabs at the top are the same as the tabs at the bottom of CPRS
- Vital Sign and Lab trending ability is available
- This is a Read only version and data cannot be entered, modified or deleted

**Notes:**
CareView is a read only version of CPRS.  It has the same tabs as CPRS does at the bottom of the screen but they are located at the top of the screen.  It allows graphing of vital signs and lab values.

CareView is a read only version of CPRS.  Data cannot be entered, modified or deleted. 

## wCodeBlue

- Under Development

**Notes:**
This package is being designed to record the activities during cardiopulmonary resuscitation.  The goal is also to be able to collect data nationally to evaluate trends in CPR and determine if actions can be done to improve survivor rates.

## BCE Implementation Activities

- Key Activities:
- Forming local implementation team and plan
- Selecting initial clinical areas for implementation
- Hardware shipping, receiving and set-up
