The bridge to http://www.housecallsweb.com/ works as follows. Activate HouseCalls from the Program Links setup.

You can make the HouseCalls button show in as many of the main modules as you want by holding down the Ctrl key and clicking in the list at the left.
There are two properties you can edit in the middle of the window. Double click to edit. The first lets you choose between passing the PatNum or the ChartNumber when exporting data. The second is the path where the data will be exported to. The data is always exported to a file called Appt.txt in the path specified. The file is a simple comma-delimited text file which has the following columns:
LastName
FirstName (or we substitute Preferred Name if
exists)
PatientNumber (Can be PatNum or ChartNumber, depending on what user
selected)
HomePhone
WorkNumber
EmailAddress
SendEmail (this will be
true if email address exists.r)
Address
Address2 (although they did not
offer this as an
option)
City
State
Zip
ApptDate
ApptTime
ApptReason
(procedures descriptions-user can't edit)
DoctorNumber (for the Doctor, we
currently use the patient primary provider. Otherwise, we would run into trouble
with appointments assigned to a specific hygeinist.)
DoctorName
When you click on the HouseCalls button, you get to select a date range of appointments to confirm:

Then, click OK to create the text file. The HouseCalls software will upload the text file sometime in the middle of the night.
