5 th Annual PBM Pharmacy Informatics Conference Are You Ready for MOCHA V 2.0? DATE/MONTH 2012 Jim Hewins, Kansas City MO Dionne Roney, Charleston SC

VETERANS HEALTH ADMINISTRATION 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 1

VETERANS HEALTH ADMINISTRATION 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 2

VETERANS HEALTH ADMINISTRATION 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 3

VETERANS HEALTH ADMINISTRATION 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). 4

VETERANS HEALTH ADMINISTRATION 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) 5

VETERANS HEALTH ADMINISTRATION CPRS versus Vista Order Checks 6 Maximum Single Dose Check could not be performed for Drug: IPRATROPIUM BROMIDE 17MCG 200D ORAL INHL Reason: No dosing information found in database.

VETERANS HEALTH ADMINISTRATION Dose Warning for Single Ingredient Drug Order details: Orderable Item: METFORMIN HCL TAB,ORAL Dosage Ordered: 3000 (MG) Dispense Units: 3 Noun: TABLETS Route: ORAL (BY MOUTH) Schedule: BID-WF Dose warning text: METFORMIN HCL 1000MG TAB: Single dose amount of 3000 MILLIGRAMS exceeds the maximum single dose amount of 1000 MILLIGRAMS. 7

VETERANS HEALTH ADMINISTRATION Dose Checks Calculations Dependent on Body Surface Area or Weight Data Patient data: DOB: SEP 6,1946 (65) Ht(cm): (03/13/2012) Wt(kg): (03/14/2012) Dose warning text: ENOXAPARIN 150MG/ML INJ SYRINGE 1ML: Single dose amount of 150 MILLIGRAMS exceeds the maximum single dose amount of MILLIGRAMS. 9

VETERANS HEALTH ADMINISTRATION Factors Used to Derive a Recommended Dose Patient Age Height/Weight/BSA (when applicable) Dose Form Dose Unit Medication Route Frequency Duration Rate 10

VETERANS HEALTH ADMINISTRATION 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 11

VETERANS HEALTH ADMINISTRATION 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 12

VETERANS HEALTH ADMINISTRATION 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) 13

VETERANS HEALTH ADMINISTRATION 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

VETERANS HEALTH ADMINISTRATION Lookup Dosing Check Info For Drug 15

VETERANS HEALTH ADMINISTRATION Dose Check Exclusions Exclude Dosage FormOverride ExclusionWhat happens No Order Checks Occur NoYesOrder Check doesn’t Occur YesNoOrder Check doesn’t Occur Yes Order Checks Occur 16

VETERANS HEALTH ADMINISTRATION 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 17

VETERANS HEALTH ADMINISTRATION 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 one- half tablets = 3.5 tablets). If a match cannot be determined, then no order check will be performed 20

VETERANS HEALTH ADMINISTRATION 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)

VETERANS HEALTH ADMINISTRATION Medication Route Issues Maximum Single Dose Check could not be performed for Drug: DIGOXIN (LANOXIN) 0.25MG TAB Reason(s): Invalid or Undefined Dose Route 23

VETERANS HEALTH ADMINISTRATION Medication Route Issues NAME: NEBULIZATION// Already mapped to: Stnd Route: 'INHALATION' FDB Route: 'INHALATION‘ Order Check Returned: Maximum Single Dose Check could not be performed for Drug: ALBUTEROL 0.5% (MULTI-DOSE) INHL SOLN Reason: No dosing information specific to maximum single dose is available from the database. Local Route: 'NEBULIZATION' has been remapped to Stnd Route: 'NEBULIZATION' FDB Route: 'NEBULIZATION‘ Order Check Returned: ALBUTEROL 0.5% (MULTI-DOSE) INHL SOLN: Single dose form amount of 3 MILLILITERS exceeds the maximum single dose form amount of 2 MILLILITERS. 24

VETERANS HEALTH ADMINISTRATION Factor: Frequency Used to calculate a total daily dose Two new fields were created in file 51.1 EXCLUDE FROM ALL DOSING CHECKS: EXCLUDE FROM DAILY DOSE CHECK:

VETERANS HEALTH ADMINISTRATION 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 Calculated via a formula 26

VETERANS HEALTH ADMINISTRATION IV orders (continued) Continuous Order marked as Premix: – Cefazolin 10 gms in Dextrose 5% 500 ml IV at 100 ml/hr – No dosing information in FDB Continuous Order marked as Premix: – Heparin 20,000 units in 500 ml 42ml/hr 29

VETERANS HEALTH ADMINISTRATION 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 30

VETERANS HEALTH ADMINISTRATION Free Text Infusion Rates If the infusion rate is in the free text format of – ‘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 31

VETERANS HEALTH ADMINISTRATION Free Text Infusion Rates con’t If the infusion rate in the format or ‘X – ‘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 ‘M 2’, 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 32
