So, he’s going to talk about?

 PEDIATRIC MINMAX DOSE CHECKING  Pediatric  definition from NC Children‟s Hospital  subset of Pediatric is Neonatal  mandated application of definitions  pathway initiation logic  MinMax  a whole different beastie from adult  consider data from children‟s Tylenol

OBJECTIVES

 Information from this presentation will assist you to:  Identify patient safety considerations affecting design and integration of custom MinMax Dose Checking schemata  Analyze Computerized Provider Order Entry pathways for potential loci of weakness which result from introduction of customized MinMax Dose Checking schemata  Develop systems and clinical strategies for implementation of custom MinMax Dose Checking with Computerized Provider Order Entry systems

STATEMENT OF WORK

 SERVICES REQUESTED  Provide customized Pediatric MinMax dose checking for top 500 drugs identified by PED Clinical Pharmacists  dynamic age ranges  variable MinMax dose determination  multiple dosing methodologies

BENEFITS

 KIDS – KEEP „EM SAFE!  Drivers  UNC Hospitals, Division of Pharmacy Services  UNC School of Medicine, Department of Pediatrics  Medication Errors  Susceptible Population  Data model for proposed MinMax solution  “Pediatric Dosage Handbook, 13th edition”

PROCESS

 ANALYZE  clinical considerations  OAS considerations  BUILD  EVALUATE & REVISE  LEARN POST GO-LIVE  SUMMARIZE

ANALYSIS

 ANALYSIS  Clinical considerations     dynamic age ranges variable MinMax dose determination multiple dosing methodologies patient safety

 ANALYSIS  Clinical considerations  dynamic age ranges  multiple (one to seven) age ranges  defined ranges vary per drug

 ANALYSIS  Clinical considerations  variable MinMax dose determination  dose  dose / body metric  dose / kg  dose / m2

 ANALYSIS  Clinical considerations  multiple dosing methodologies  simple dosing  dose (/ body metric) by indication  mixed dosing (under development)  dose / body metric / age  dose / age  dose / m2 / age  dose / kg / age  dose / body metric / age variable by route (IM vs IV)

 ANALYSIS  Clinical considerations  patient safety  differences in practice for tertiary care institution  increased severity of illness  special populations  MinMax check first line of defense against error  clinical checking remains in place

 ANALYSIS  OAS considerations     patient safety issues profile data structure logic structure split process

 ANALYSIS  OAS considerations  patient safety issues  pathway insertion  med order processing  (custom) pediatric calculators  (custom) neonatal MinMax checking  (Siemens) adult MinMax checking  pathway integration  ability to loop back / revise  (custom) pediatric calculators

 ANALYSIS  OAS considerations  profile data structure  three separate profiles  dose units / dose  dose units / body metric  dose units / body metric by indication  data entry screens  simplify to minimize transcription error

 ANALYSIS  OAS considerations  logic structure  limitations of TCL-driven approach  35 for match in each MinMax check type  >150 for all checks in each MinMax type  more difficult to visualize structure and interplay

 ANALYSIS  OAS considerations  split process  perform dose check & generate error codes  display errors (MinMax warning)

 ANALYSIS  OAS considerations  logic structure  developed from gestalt view / unified processing  heavy use of “%GECNGHX” fields  comment  identify  data manipulation  U-fields  3-fields

BUILD

 BUILD  age matching  dose frequency  MinMax check types

 BUILD  age matching  age groups within the NC Children‟s Hospital  extreme variation in age ranges per medication  C0621 & C0622  multiple definitions per age range  serial (up to seven) dynamic age ranges per MinMax check  logic repeated through seven controllers

 BUILD  dose frequency  calculation issues with text frequencies  loop to strip off text data  integer to convert to number  model on “Pediatric Dosing Handbook”  convert all frequenciew to # times / day

 BUILD  MinMax checking types  dose unit / dose  dose unit / body metric  indication driven

 BUILD  MinMax checking types  dose unit / dose  profile error (predefined message)  dose units error  route error  absolute max dose error  one-time min dose error  one-time max dose error  age-related min dose error  age-related max dose error  age-related 24hr min dose error  age-related 24hr max dose error

 BUILD  MinMax checking types  dose unit / body metric  profile error (predefined message)  dose units error  route error  absolute max dose error  one-time min dose error  one-time max dose error  age-related min dose error  age-related max dose error  age-related 24hr relative min dose error  age-related 24hr relative max dose error  age-related 24hr actual max dose error

 BUILD  MinMax checking types  indication driven  same MinMax check data as dose / body metric  additional requirements to have user select indication  match med to profile  generate indication selection  match med + indication to MinMax data

EVALUATION & REVISION

 EVALUATION & REVISION  %GECNGHX commenting paid off!  tedious revision process for initial build  Gestalt + Team paid off!  translation of prior build for next prong  minor revisions

POST GO-LIVE LESSONS

 POST GO-LIVE LESSONS  NO issues with pathway at go-live!  few data issues discovered during the months after  easy repair / revision  BIG picture thinking & TEAMWORK paid off!  design involved a dozen people  gestalt view vastly simplified subsequent prongs  Be careful what you wish for  clinically inappropriate MinMax warnings  10% fuzzy logic

SUMMARY

 SUMMARY  It‟s all about patient safety  Thinking ahead of the game plan pays off  OAS Gold‟s power and flexibility are incredible
