Are You Ready for MOCHA V2

Report
5th Annual PBM Pharmacy Informatics Conference
Are You Ready for MOCHA V 2.0?
Jim Hewins, Kansas City MO
Dionne Roney, Charleston SC
DATE/MONTH 2012
MOCHA 2.0 Objectives
• Discuss the timeline the sites will need to consider prior to
implementing MOCHA V 2.0
• Explain the tasks that need to be completed prior to
implementing MOCHA V 2.0
• Describe the setup for doses to enable the dose checks to
occur properly
• Explain how to trouble shoot problem order checks
VETERANS HEALTH ADMINISTRATION
1
Types of Dosage Information
• Max single dose – this is the individual dose
amount, whether it is given once a day or 24
times a day
• Total daily dose – Dose x Frequency (per 24h)
• General Dosage Range – Is provided when
there is a problem with the order and dosage
checks cannot be performed
VETERANS HEALTH ADMINISTRATION
2
MOCHA 2.0 – four increments
• Increment A - Maximum single dose check for simple
and complex medication orders. First increment to be
released
• Increment B - Daily dose range check. Includes general
dosing information when a dosing check cannot be
performed – simple orders only
• Increment C - Daily dose range for complex orders.
Includes general dosing information when a dosing check
cannot be performed
• Increment D - TBD
VETERANS HEALTH ADMINISTRATION
3
MOCHA 2.0
• Both Outpatient Pharmacy and Inpatient Medications
• Provides error messages with reasons at the order level when
a Maximum Single Dose Order Check cannot be performed for
Pharmacy users
• Provides a generic error message at the order level when
Maximum Single Dose Order Check cannot be performed for
CPRS users
• Adds a check during installation to see if Pre-Release setup
work has been completed (PSS*1*129 & PSS*1*147, PRE v0.5
PRE-RELEASE patches).
VETERANS HEALTH ADMINISTRATION
4
MOCHA 2.0
• Adds new fields to the Administration Schedule file (#51.1)
• Modify Standard Schedule Edit (PSS Schedule Edit) option to
allow editing of the new dosing exclusion fields
• Modify Administration File Report (PSS Schedule Report)
• Apply the ‘all Dosage Checks exclusion’ for a schedule when
processing outpatient and inpatient medication orders
• Creates a new Pharmacy Data Management (PDM) option
called Lookup Dosing Check Info for Drug
• Adds new entries to the VistA DOSE UNIT file (51.24)

Factors Used to Derive a Recommended Dose
•
•
•
•
•
•
•
•
Patient Age
Height/Weight/BSA (when applicable)
Dose Form
Dose Unit
Medication Route
Frequency
Duration
Rate
VETERANS HEALTH ADMINISTRATION
10
Factor: Patient Age
• Recommended doses vary according to a patient’s
age
• FDB stores dose data according to patient age
• Doses are not always established and available for a
certain age, but this is more common with pediatric
dosing than geriatric dosing
VETERANS HEALTH ADMINISTRATION
11
Factor: Patient Height, Weight, BSA
• Calculated doses for specific drugs are done when a weight or
BSA value is relevant in the determination of an appropriate
dose
• Some drug dosages are only weight/BSA dependent for
specific age groups (i.e. weight may be relevant on a 90 year
old, but not on a 50 year old
VETERANS HEALTH ADMINISTRATION
12
Factor: Dose Form
• Doses are stored differently based on the drug’s
dosage form (i.e. oral, IV, transdermal)
• Some dosage forms are excluded from dosing order
checks (i.e. creams, ointments)
VETERANS HEALTH ADMINISTRATION
13
Dose Check Exclusions
•
•
•
•
Supplies (bandages, syringes)
Compounded items not matched to NDF
Large volume IV solutions – non Premix
Items that don’t require a dose check, but that have a
dosage form that does generate checks
• Drugs with excluded dosage forms (i.e.. creams,
ointments) but, the exclusion can be overridden at the
NDF level

16
Factor: Dose Units
• The dose unit on an order must either match the unit
that FDB has stored, or else be able to convert to
that unit.
• If the dose unit does not match the FDB dose unit,
then the order check will not occur and an error
message will display
VETERANS HEALTH ADMINISTRATION
17
Dose Units for Single Ingredient Drugs
• Generally used for single ingredient drugs that are
administered via po, SC, or IM
• The most common type of dose unit (mg, gm, units)
• Possible types of FDB Dose Unit Conversions
• Metric conversions – wide range (i.e.. mcg to mg)
• Numeric conversions between standard units and
metric units (i.e. Cm to In, Oz to Tsp, Tsp to mL,
MMU to IU)
VETERANS HEALTH ADMINISTRATION
Dose Units (continued)
• Dose form type units – Used for non-po solids
(patches, inhalers), multi-ingredient drugs
• FDB selects the type of dose units for an item
• Patch dose unit is “ 1 patch”, rather than
75mcg
• Inhaler dose units are variable and include
inhalations, sprays, puffs, etc. Currently,
they sometimes also include metric doses.
VETERANS HEALTH ADMINISTRATION
Non-Standard Doses
• Fractional doses – no problem
• Free-text doses – different assumptions in CPRS versus.
backdoor, because of the way that a dispense drug is selected
in each package
• The pharmacy packages can perform some sophisticated
auto-population logic for free-text doses (i.e. three and onehalf tablets = 3.5 tablets). If a match cannot be determined,
then no order check will be performed

Factor: Medication Route
• If a medication route is not accurately mapped,
then a dose check will not occur
• FDB Doses are tied to specific routes (IV versus
IM), error messages will display if an invalid
route is selected
• Sometimes FDB is too limiting with its expected
med route.
• Patches – must be transdermal not topical
• Inhalers – Nebulization versus Inhalation; Oral Inhalation versus Oral
(Albuterol Solution)

IV Orders
– IV orders based on various business rules, the
single dose amount (SDA) and Dose Unit (DU)
could be derived from
• IV solution volume
• IV Additive strength/unit
• Infusion Rate

– Heparin 20,000 units in 500 ml 42ml/hr
VETERANS HEALTH ADMINISTRATION
29
IV Orders (continued)
If the Drug can be administered via a ‘CONTINUOUS’ FDB Dose Route, the single dose
amount shall be derived using the following formula:
Single Dose Amount/Dose Rate =
(IV Additive Strength & Unit/Volume of IV Solution) * Infusion rate (ML/HR)
Example: (20000Units/500ML) * 42ML/HR = 1680 Units/HR
Single Dose Amount = 1680
Dose Units = Units (FDB EQUIVALENT is UNIT(S))
Dose Rate Unit = HOUR
VETERANS HEALTH ADMINISTRATION

Free Text Infusion Rates
• If the infusion rate is in the free text format of ‘XML/[email protected]’
– ‘X’ = single dose amount
– The FDB equivalent of ‘ML’ shall be sent to the interface for the Dose Unit
– Applies to CPRS and Pharmacy backdoor
• Continuous Order marked as Premix:
– Heparin 20,000 units in 500 ml Infuse at 42 ml/[email protected]

If the infusion rate in the format ‘XY/P/[email protected]’ or ‘X<space>Y/P/[email protected]’
– ‘X’ shall represent the numeric dose
– ‘Y’ shall represent the dose unit
– ‘P’ shall represent a patient parameter
• If the values for ‘P’ are ‘KG’ or ‘M2’, the software will multiply the
parameter value for the patient by the numeric dose to calculate the
single dose amount sent into the interface
– ‘R’ shall represent the dose rate unit/duration rate
• If the values for ‘R’ are ‘MIN’, ‘HR’ or ‘DAY’, the software shall set the Dose
Rate Unit/Duration Rate equal to ‘MINUTE’, ‘HOUR’ or ‘DAY’ respectively.
– ‘N’ shall represent a numeric value
Applies to CPRS entered order only

What do I need to do?
• Local Medication Route Mapping
– As you are changing medication routes, remember to check
orderable items as well as CPRS quick orders that may be using
old/invalid medication routes
• Local Possible Dosage Setup
– FDB uses dose units to calculate and match a dose from their database.
– Review Local Possible Dosages Report (PSS LOCAL POSSIBLE DOSAGES ) option
to verify
– Populate the dose Unit and corresponding Numeric Dose field
• Frequency Review
• Enter/Edit Additive Frequency for IV Additives
