听力原文：Now, text messaging is increasingly being used by UK hospitals to remind patients about outpatient appointments — and could potentially save the Nati6nal Health Service millions of pounds every year. Ealing Hospital in West London sends 20 texts per day, reminding the patients in advance of the date and time of their appointment. Before using the text messaging system, the hospital relied solely on sending patients a letter as a reminder.
Instead of sending patients a letter as a reminder, now most UK hospitals use short messages to remind the patients of appointments.

Dear Mr. Kahoano,
I am writing to confirm the agreement we made last week to hold a series of meetings over the next month to review your implementation of the security pilot program.
As we previously discussed, we will use the meetings to:
— determine the effectiveness of the program,
— identify the strengths and weaknesses of the program, and
— propose solutions to address areas of weakness.
As agreed, meetings will be held every Wednesday from 1:00 P.M. until 2:30 P.M. at your office in Holualoa, with our first meeting being held on Wednesday February 28. Virginia Madison, of your loss prevention department, will organize and lead all of the meetings. At the end of the process, she will also draft a summary of the meetings so that we may better determine the success of the security pilot program.
If you have any questions or would like to add anything please call me at 808-326-1599. I look forward to seeing you on Wednesday.
Sincerely,

Professional Security, Inc.
