ABSTRACT:

TECHNICAL FIELD
The present invention relates in general to a clinical information system and a method for using it for patient charting or record keeping purposes. The invention more particularly relates to a clinical critical care path system, which facilitates the ability for an improved careful maintenance of patient care.
BACKGROUND ART
Charting the progress of a patient after being admitted to a medical care facility for medical or surgical reasons has been a traditional practice in the medical profession. Such charting typically involves monitoring the condition of a patient, collecting information relative to the physical condition of the patient, and logging the collected information onto a patient chart for review and analysis by trained medical personnel.
To make such charting more efficient and cost effective, various monitoring and information gathering systems have been developed to provide automatic clinical record management. For example, reference may be made to the following United States patents and published articles, as follows: U.S. Pat. Nos. 5,361,202; 5,267,155; 5,077,666; 5,072,383; 4,893,270; 4,878,175; 4,838,275; 4,815,474; 4,803,625; 4,731,726; 4,712,562; 4,695,954; 4,674,652; 4,665,499; 4,622,185; 4,577,638; 4,531,527; 4,519,398; 4,513,294; 4,489,387; 4,473,884; 4,465,077; 4,428,381; 4,422,081; 4,417,306; 4,412,292; 4,363,368; 4,347,213; 4,320,766; 4,296,756; 4,272,878; 4,270,547; 4,227,526; 4,216,462; 4,197,854; 4,173,971; 4,151,831; 4,150,284; 4,130,881; 4,004,577; 3,996,928; 3,963,019; 3,910,257; 3,872,448; 3,872,251; 3,830,896; 3,765,406; 3,726,270; 3,696,805; 3,426,150; 3,302,828; 3,106,701; 2,891,111; and 1,078,090; and Walter A.

Vol. 6, No. 3, March 1989, each of the foregoing patents and published articles being incorporated herein by reference as though fully set forth herein.
As disclosed in the foregoing publications, various clinical information systems display, monitor and chart patient physiological conditions. Such systems enable a user to enter information regarding the condition of a patient and to have lists of tasks to be performed regarding a patient to be generated.
While such systems may have been satisfactory for some applications, they have not proven to be entirely satisfactory for some applications relative to improving patient management on a cost effective basis. More particularly, a treatment plan for each new patient would still necessitate suitable preparation, usually by more than one highly trained healthcare provider. Such preparation time, while an important task, has been burdensome and not always efficient and cost effective.
With the rapid rise in medical treatment costs and hospitalization costs, it has become very important to be more efficient to achieve overall cost saving reductions. To achieve such cost savings, delivery of care to large groups of patients must be consistent. In this regard, consistent delivery of care requires detailed documentation for each patient and periodic monitoring of each patient to evaluate patient progress.
Consistent delivery therefore requires a definitive plan to enable healthcare providers to provide high quality care. Such a plan optimizes delivery of care, results in quicker patient recovery, helps to eliminate unwanted and undesired interventions. In short, such a plan is designed to achieve the desired goals for a patient.
Thus, for any given medical condition, to achieve cost saving reductions there must be uniform and consistent delivery of healthcare; measurable objective documentation; and detailed standard of care procedures.
One attempt at achieving the consistent standard of care and the provision of detailed documentation by the healthcare providers has been to develop a pre-printed critical care path document or form which incorporates predefined hospital standard of care procedures, care provider orders and expected outcome results for a given diagnosis.
While such critical care flow forms may have helped to improve patient management and improved system utilization to a certain degree, such critical care flow sheets have not proven entirely satisfactory. In this regard, the typical preprinted critical care path document for any given diagnosis is a document which is very difficult to use and to read. It contains a large number of small-sized time-line spaces for entry of the patient deviation codes for each day of treatment, or for each stage of patient care. Such small spaces result in small handwritten entries which can be illegible, or which can lead to an unwanted and undesirable transcription error of some type.
The entry of only code information requires utilizing another form for entry of the deviation information. The description of the deviation or other desired information as an explanation of the simple code information entered on the care path sheet, must be entered on other sheets of paper. Thus, not only unwanted and undesirable transcription errors can result, but also all necessary patient information is not available on a single document. Instead, multiple forms must be employed for entry of code information and text information.
Still yet another problem associated with preprinted critical care path flow sheets is that the preprinted critical care path flow sheets are configured for a single diagnosis activity only, such as a treatment plan for a patient undergoing hip replacement surgery. In this regard, if a patient is confined to a treatment facility and requires treatment for two or more surgical activities, or if a secondary diagnosis arises, such as where a surgical patient subsequently develops a medical problem, such single critical care path forms cannot be used. The preprinted forms do not have sufficient space to permit the addition of other care paths for multiple diagnoses. Moreover, if two or more single diagnosis forms are used, conflicting treatment plans may result. More particularly, pre-printed forms are not necessarily detailed enough for a given patient. For example, a patient involved in an automobile accident nay have a broken arm, require surgery to stop internal bleeding, be a diagnosed diabetic, require a hip replacement and develop secondary pneumonia two days after admission for treatment. Each diagnosed problem, in turn, could result in a multiple number of deviations. In short, because of the large number of permutations and combinations the use of multiple flowsheet documents gr
