There is no room for overlooked appointments or misunderstandings in a well run office. If a patient casually mentions a friend or relative that has a health disorder and is not a chiropractic patient, you may suggest a specific piece of literature that the patient may wish to forward. Office policies, procedures, records, forms, systems, supplies, equipment, and furnishings are but vehicles to reach the goal of professional health care. The assistant should never enter an appointment unless there is reasonable assurance that the appointment will be kept. Getting on 7 little words. Number: shows a unique number that identifies the supply request. This review guards against an inaccurate entry. Besides patient record files, card files that can remind the assistant of important dates and matters to be taken up in the future reduce burdening memory with sundry details. When an assistant is seated within the reception room, conversations are not private, and much time can be lost in idle conversation.

Some doctors do not like the restriction of a standardized format. Three basic points should be remembered: Patients in severe pain take precedence over others with less priority. The objective is to see that each practice day represents a minimum of lost production time. A CA should never let a patient browbeat her (eg, for the sake of economy or expediency) to do anything that would not be ultimately in the patient s best interests.
Please hold, and I ll see if I can get Dr. Jones on the line for you, Mrs. Peters. If the material is stored in boxes, label the contents of each box on the outside.

It s no wonder their words sound mumbled, shut in, or swallowed instead of being nicely formed and directed. If the practitioner is lackadaisical, deficient in professional deportment and authority, does not take time to adequately train his assistants or supervise their performance, he will find that patients reflect this attitude in their attitudes toward the recommended appointment schedule. The doctor assumes responsibility for proper case management, but he cannot do this if the patient does not grant the authority to direct and schedule necessary appointments for care and evaluation of progress.
This memo should contain date, time of call, name of person who called, telephone number of caller in case he is to be called back, the main points of the conversation, what the assistant did about the call, and, if necessary, some comments about the conversation.

The appointment system has since slowly gained in popularity and is now used by most practitioners. Maintaining and replacing your equipment is an important step towards staying comfortable and compliant with your CPAP therapy. A procedure is a plan, and a plan is not a permanent order because conditions change with time, personnel changes, and growth of the practice. When the appointment book shows an insufficient number of patients scheduled to maintain full production capabilities, a system of recalls should be considered. Rather, say that it seems you have a bad connection and ask the caller to speak a little louder or slower.
