ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to systems, methods, and computer products for clinical information capture and management and specifically to systems and processes by which electronic medical records may be created and modified in the clinical environment of a patient encounter.
2. Discussion of the Background
An average patient load for a medical specialist such as an orthopaedic surgeon is twenty patients per half day.
In order for physicians to be paid, insurance companies require the physicians to prepare specific individualized documentation for each patient. The guidelines and requirements for this documentation are strict, and significant financial and criminal penalties are possible if these guidelines are not followed. One set of guidelines is the Health Care Finance Administration guidelines (HCFA), which requires that a complete history be gathered and recorded on all patients. Medicare auditors reason that if a procedure is not documented, the procedure did not happen. Improper documentation may result in fines and a possible jail term.
Medical record documentation is required to record pertinent facts, findings and observations about an individual's health history, including past and present illnesses, examinations, tests, treatments, and outcomes. The medical record chronologically documents the care of the patient and is an important element contributing to high quality care.
The patient encounter (the interaction between the physician and the patient which occurs, for instance, in a physician's office) may be considered to be divisible into a number of segments: a history taking segment; a physical examination segment; a decision making segment, which includes the differential diagnosis phase, a diagnostic studies phase, a definitive diagnosis phase and a treatment plan phase; a documentation segment, which includes creating a record of the findings, decisions, and recommendations of the patient encounter; and a communication segment which includes sharing the documentation created during the patient encounter including reports, instructions, and requests.
Present systems and methods for capturing the information produced during a patient encounter rely heavily on dictation by the physician. This dictation may take as much as five minutes or more per patient encounter, so that the typical half day clinical session requires at least one hundred minutes of dictation by the physician. This dictation is done either between patient encounters, if there is time available, or at the end of the entire clinical session. In many cases the dictation must be done at the end of a physician's working day, which is sometimes well beyond normal working hours.
The principles of documentation that follow are applicable to all types of medical and surgical services in all settings. For Evaluation and Management (E/M) services, the nature and amount of physician work and documentation varies by type of service, place of service and the patient's status.
The levels of E/M services are based on four types of history (problem focused, expanded problem focused, detailed, and comprehensive). Each type of history includes some or all of the following elements: chief complaint (CC); history of the present illness (HPI); review of systems (ROS); and past family and/or social history (PFSH).
The chief complaint is a concise statement describing the symptom, problem, condition, diagnosis, physician recommended return, or other factor that is the reason for the encounter.
The history of present illness is a chronological description of the development of the patient's present illness from the first sign and/or symptom or from the previous encounter to the present.
A review of systems is an inventory of body systems obtained through a series of questions seeking to identify signs and/or symptoms which the patient may be experiencing or has experienced. For purposes of review of systems, at least the following systems are recognized: constitutional systems (e.g., fever, weight loss); eyes; ears, nose, mouth, throat; cardiovascular; respiratory; gastrointestinal; genital urinary; muscular skeletal; integumentary (skin and/or breast); neurological; psychiatric; endocrine; hematologic/lymphatic; and allergic/immunologic.
The past, family and/or social history consists of a review of three areas: past history (the patient's past experiences with illnesses, operations, injuries, and treatments); family history (a review of medical events in the patient's family, including diseases which may be hereditary or place the patient at risk); and social history (an age appropriate review of past and current activities).
For purposes of examination, the following body areas are recognized: head, including the face; neck; chest, including breasts and axillae; abdomen; genitalia, groin, buttocks; back, including spine; and each extremity.
The extent of examinations performed and documented is dependent on clinical judgement and the nature of the presenting problems. They range from limited examinations of single body areas to general multi-system of complete single organ system examinations.
The levels of evaluation and management services recognize four types of medical decision making (straightforward, low complexity, moderate complexity, and high complexity). Medical decision making refers to the complexity of establishing a diagnosis and/or selecting a management option as measured by the number of diagnoses and/or the number of management options that must be considered; the amount and/or complexity of medical records, diagnostic tests, and/or other information that must be obtained, reviewed and analyzed; and the risk of significant complications, morbidity and/or mortality, as well as comorbidities, associated with the patient's presenting problems, the diagnostic procedures and/or the possible management options.
The number of possible diagnoses and/or the number of management options that must be considered is based on the number and types of problems addressed during the encounter. The complexity of establishing a diagnosis and the management decisions that are made by the physician.
The amount and complexity of data to be reviewed is based on the types of diagnostic testing ordered or reviewed. A decision to obtain and review old medical record and/or obtain history from sources other than the patient increases the amount and complexity of data to be reviewed.
The risk of significant complications, morbidity, and/or mortality is based on the risks associated with the presenting problems, the diagnostic procedures, and the possible management options.
The extent of the history that is required for proper documentation varies according to the patient's presenting problem. Certain conditions require a limited history, while other complaints are more involved and demand a more complete history. A complete history should include the patient's chief complaint and the history of the present illness, a review of systems, and past medical, family, and/or social history. If a review of systems and/or a past medical, family, and/or social history have been documented earlier, the physician does not need to repeat this information. However, he or she should indicate that the previous information was reviewed and then updated, if appropriate. A review of systems and the past medical, family, and/or social history may be completed by ancillary staff or the patient. The record should include a note by the physician confirming the information that was documented by others and supplementing, as appropriate.
The type of physical examination that is performed depends upon the patient's presenting problem and the physician's clinical judgement. The examination may be limited to the affected area, or it may involve an entire organ system. The examination can be more extensive by detailing a complete multi-system examination. The guidelines defined 7 body areas and 12 organ systems for the purpose of phys
