• wherein the computer processor retrieves the plurality of questions concerning the health condition of the patient from the database and causes the voice generator to generate voice output representing the plurality of questions,
• wherein the patient responds to the plurality of questions and the computer processor storing information concerning the health condition of the patient in the patient record, which information can be reported to a health care provider to enable the health care provider to then make a diagnosis of the patient's health condition.

A patient-initiated drug compliance system to monitor compliance by a patient in taking prescribed drugs, comprising:

• a telephone operated by a patient and enabling the patient to initiate at a time convenient to the patient, between the patient and a central monitoring system, a session for monitoring drug compliance,;
• and
• a central monitoring system coupled via a telecommunications system to the telephone, the central monitoring system generating a plurality of questions concerning compliance by the patient in taking prescribed drugs for the patient to answer by speaking responses at the telephone, and storing answers to the plurality of questions for later retrieval, the central monitoring system including
• a decoder receiving and decoding the spoken responses of the patient transmitted over the telecommunications system to the central monitoring system, the spoken responses representing compliance by the patient in taking a prescribed drug,
• a computer processor coupled to the decoder,
• a voice generator coupled to the computer processor generating voice output under the control of the computer process, said voice output transmitted over the telecommunications system to the telephone,
• a database coupled to the computer processor storing a patient record reflecting compliance by the patient in taking the prescribed drug and storing the plurality of questions concerning compliance by the patient in taking the prescribed drug,
• wherein the computer processor retrieves the plurality of questions concerning compliance by the patient in taking the prescribed drug from the database and causes the voice generator to generate voice output representing the plurality of questions, and
• wherein the patient responds to the plurality of questions using telephone, the computer processor storing information concerning compliance by the patient in taking the prescribed drug in the database.
