Lab Connect!™

 
Lab Connect!^™ offers a way to automatically integrate EBMcalc equations with your patient's actual lab data. Our EHR interoperability modules will perform the necessary calculations and return a well formatted, evidence-based note for your EHR.
 
 
Example Patient 1: Calculate and Interpret A-a Gradient

• Age = 52 years
• Inspired O2 = 50%
• pO2 = 100 mmHg
• pCO2 = 30 mmHg

To send this information, configure your lab interface to send an HTTP request like this:
 
     AAGradient.htm?Age=52&Percent_Inspired_O2=50&p_CO2=30&p_aO2=100
 
To have the calculation done and result posted to the EHR immediately, append "post=now" to the very end of the parameter list:
 
     AAGradient.htm?Age=52&Percent_Inspired_O2=50&p_CO2=30&p_aO2=100&post=now
 
Query string error handling examples

Example Patient 7: Assess Severity of Acute Congestive Heart Failure by Decision Tree

• pH = 7.38
• Diabetes present = Yes
• Heart rate = 130
• Respiratory rate = 24
• Serum Creatinine = 2.1

Here is the HTTP request to start the decision tree:
 
     HeartFailure.htm?ph=7.38&dm=yes&hr=130&rr=24&cr=2.1
 
 
Example Patient 8: Calculate the 10-Year Risk of Cardiovascular Disease in a Male

• Systolic Blood Pressure = 150
• Total Cholesterol = 280
• HDL Cholesterol = 40

• Cigarette smoker: Yes
• Diabetes present: No

To send this information, configure your lab interface to send an HTTP request like this:
 
     Framingham08_M_Patient.htm?Age=60&Systolic_Blood_Pressure=150&Total_Cholesterol=280&HDL_Cholesterol=40&Sys_BP_Factor=Yes&Cig=Yes&DM=No

• Stature at age 14: 160 cm
• Stature at age 19: 165 cm

Example Patient 13: Serum to Ascites Albumin Gradient [LOINC input and output in XML]

• Serum Albumin: 5.3 mg/dL
• Ascites Albumin: 2.2 mg/dL

Here is the HTTP request to calculate the SAAG:
 
     AscitesAlbGradient.htm?1751-7=5.3&1749-1=2.2
 
 
Example Patient 14: Body Mass Index in Boys Ages 2 to 20

• Weight: 120 lb

Here is the HTTP request to calculate age specific BMI percentile:
 
     BodyMassIndexBoys.htm?Age=15&Height=60|in&Weight=120|lb
 
 
The parameter values are assumed to be in certain units for the initial calculation display. If you leave one or more parameters out of the HTTP GET request, the missing parameters and any default values will be entered from the EBMcalc source files.
 
PLEASE NOTE: Parameter names are case sensitive, and the GET request should contain no blank-space characters. If you are sending data for a radio button parameter you may indicate either the discrete option name or actual numeric value in the HTTP request. If the option name contains blank spaces (see catalog) these spaces must be escaped with ASCII equivalents in the request.
