Chapter 40: Medical Office Computerization
How does a practice management program work like a spreadsheet application program?
It can perform calculations in order to generate financial records and financial reports for the office.
What happens to items in RAM when a computer is turned off?
It is dumped out.
What are three important aspects of maintaining a computer system?
It is important to periodically perform disk cleanup and disk defragmentation. In addition, a system administrator should be responsible for overall system and network functioning.
What is the function of the microprocessor (central processing unit or CPU)?
It is located on the main computer unit and runs the computer.
What are the advantages of medical office computerization?
Large amount of data can be processed quickly, items can be prepared and processed in a short period of time, repetitive tasks can be performed in which information is used again but in a different format, the status of functions can be tracked, data are easy to retrieve when needed.
What is an audit trail?
Log that keeps track of data entry to detect irregularities.
What computer hardware is necessary to perform administrative procedures in the medical office?
Main computer unit, monitor, computer keyboard and mouse, and printer.
List two examples of output devices.
Monitor, printer.
How does a medical office minimize the effects of a computer system malfunction?
Most medical offices are connected to some kind of network or server that stores information and provides backup systems.

A glare filter only reduces unavoidable reflections, whereas a privacy filter also blacks out the image to anyone who is not directly in front of the monitor.
What is an advantage of transmitting prescriptions electronically?
A national database can quickly match the prescription to a patient's entire medication history. This can identify patients who see more than one physician for the same complaint.
What procedures typically are performed by a medical assistant using an EMR?
Accessing the daily schedule, selecting a patient, entering the time the patient checks in, entering the patient's chief complaint, entering or reviewing the patient history, entering or reviewing patient allergies, entering or reviewing the patient's current medications, entering vital signs values, entering measurements, entering laboratory test results, entering results of other tests.

Advantages: small, lightweight, compact, uses little power. Disadvantages: sometimes difficult to view images from an angle.
How should the computer keyboard be positioned to prevent muscle fatigue?
At a level that is lower than that of a conventional desk.
What is secure messaging within the EMR, and why is it more secure than e-mail?
Clinical messaging (secure messaging within the EMR) is a type of e-mail that functions within the electronic medical record system. It is considered more secure than e-mail because access to the EMR is limited. It also has the advantage of being able to be linked to a specific patient's record.

Recording patient information, billing, and scheduling.
How are units of storage capacity of a computer named?
Storage capacity is measured in units of storage known as bytes. One byte (usually 8 bits) is approximately equal to one character, such as a letter or number.
What is database management?
Storage of data in and retrieval of data from a database.
What is the difference between system software and application software?
System software assists the computer in carrying out its tasks. Application software assists the user in carrying out computer tasks.
What is the function of main memory (RAM)?
Temporarily stores information until ready for use by the CPU.
What is the relationship between practice management software and electronic health record when both are used in a medical office?
The EMR either interfaces with the practice management software (so that the patient database can be shared) or the EMR itself has practice management functions.
How does an optical disc store data?
Through laser technology.
What is the function of the computer monitor?
To display images generated by a computer.
What are the telecommunication functions included in a practice management program?

What method of organization is used to store and retrieve information from a hard disk?
Tracks and sectors.
What should be done if water spills into the keyboard?
Turn off the computer immediately, unplug the keyboard, turn it upside down and gently shake it, keep it inverted to allow additional fluid to drain out, wipe it with a paper towel or clean cloth, let it dry in an inverted position for 24 hours.
What is voice recognition software used for?
Voice recognition software may be incorporated with the EMR so that information can be dictated into the system, or it may be a separate report function.
How should the outside casing of a printer be cleaned?
With a soft clean cloth dampened with a mild detergent solution.
What is the difference between random access and sequential access?
With random access, the computer can get to any part of the information stored in its memory directly. With sequential access, the stored data must be searched sequentially from beginning to end to locate the desired information.
What is the primary cause of improper functioning of the computer?
Exposure to environmental contaminants such as dust, dirt, and smoke.
Describe the type of data saved using the following file formats.
.bmp: Windows bitmaps handle graphics files .gif: Graphics Interchange Format is used for dimple diagrams and cartoon style images .doc or .docx: used for documents (.docx used for Microsoft Office and later) .rtf.: used for documents that can be handled by many word processing programs .txt: plain text that can be used by all word processing programs .xls or .xlsx; used by Microsoft Excel for spreadsheets (.xlsx used after 2007)

Which type of optical disc holds more information, a CD or a DVD?
A DVD holds about six times as much data as a CD.
What is the purpose of making a backup of all records stored on a computer's hard disk?
A backup, and especially continuous backups, prevents loss of data.
