A system and method for processing patient data permits physicians and other medical staff personnel to record, accurately and precisely, historical patient care information. An objective measure of a physician's rendered level of care, as described by a clinical status code, is automatically generated. Data elements used in the determination of the generated clinical status code include a level of history of the patient, a level of examination of the patient, a decision-making process of the physician treating the patient, and a "time influence factor." The quantity and quality of care information for a particular patient is enhanced allowing future care decisions for that patient to be based on a more complete medical history. Enhanced care information can be used in outcome studies to track the efficacy of specific treatment protocols. Archiving of patient information is done in a manner which allows reconstruction of the qualitative aspects of provided medical services. The medical care data can be recorded, saved, and transferred from a portable system to a larger stationary information or database system. Considerable physician and staff time are saved and precision and accuracy are significantly enhanced, by generating these clinical status codes automatically (at the point of service by the care-provider without any intermediary steps) from information recorded simultaneously with the provision of services.

A system and related techniques automatically generate optimized, best-match or sufficient assignments of care providers, such as physicians, nurses or technicians, to a patient based on clinical evidence, documentation, workload, infectious status and other factors. In embodiments, the patient's chart or other clinical record may be accessed by a rules-based engine configured with rules which relate a patient's clinical status and needs to the qualifications, certifications, capabilities and skills of care providers and select the care provider best qualified to service that patient's clinical requirements. The pool of available care providers may for example be ascertained from personnel systems recording staff schedules and estimated workload, while the qualifications of each provider indicating the categories of patient care and support that provider is qualified to provide may be accessed from a provider data store. For instance, nurses or technicians trained or certified in acute, emergency or surgical care may be identified for assignment to high acuity patients, or those presenting special or advanced care demands. According to the invention in a further regard, the provider's potential infectious exposure to other patients or from other sources may be screened to prevent that provider from being assigned to immune-compromised or other patients. Embodiments of the invention may present floor managers with a graphical display of available providers and generated assignments, which in embodiments the manager may override at their clinical discretion. Because patient needs are automatically aligned with provider capabilities, availability and other factors, the errors, oversights and inefficiencies of manual or informal assignment systems are avoided and better health care delivery can be realized.

A method for operating a cardiac rhythm management device in which a clinical state vector is computed as a combination of a plurality of parameters related to a patient's heart failure status and compared to a previously computed clinical state vector to determine a clinical trajectory indicative of changes in the patient's heart failure status. Such detected changes in status can be used both as a clinical tool to evaluate treatment and to automatically adjust the operation of the device.

The invention relates to the determination of the clinical state of a subject. In order to bring about an uncomplicated method for monitoring the clinical state of a subject and for accomplishing a diagnostic scale, such as a nociception scale, on which a certain reading corresponds to the same level for all patients, a normalization transform is applied to a measurement signal containing physiological data obtained from a patient, whereby a normalized measurement signal having a predetermined value range is obtained. The normalization transform is dependent on predetermined history data, such as previous signal data of said measurement signal. A diagnostic index dependent on the normalized measurement signal is then formed, the diagnostic index serving as a measure of the clinical state of the patient. The diagnostic index may be formed based on one or more normalized measurement signals.

The invention relates to the determination of the clinical state of a subject. A respective adaptive transform is applied to at least one measurement signal acquired from the subject, each adaptive transform being dependent on previously acquired history data, and a diagnostic index is formed, which is dependent on the transformed measurement signal(s) and serves as a measure of the clinical state of the subject. In order to reliably evaluate the clinical state of a subject on a fixed diagnostic scale during changes in the state of the subject, some or all of the previously acquired history data on which an adaptive transform is currently dependent is replaced with other previously acquired history data when a predetermined event is detected. The predetermined event is indicative of a change in the respective measurement signal, and the introduction of the said other previously acquired history data sets the transform ready for the change.

Antibodies and methods are described for the detection and quantitation of cardiac specific troponin I in samples. Cardiac-specific troponin isoforms exist in various forms in the blood, including free and complexed forms. By selecting antibodies that are insensitive and / or sensitive to these various forms, the present invention can provide immunoassays that more accurately reflect the clinical state of an individual. These described antibodies and methods can be used for providing indicators of myocardial infarction and other cardiac pathologies.

The invention relates to the determination of a diagnostic index indicative of the clinical state, especially nociceptive state, of a subject. In order to improve the quality of the determination process, desired input signals derived from the subject are monitored and the quality of the process is improved based on the monitoring. This is implemented by increasing user awareness of the reliability of the index or by controlling the measurement set-up. Quality information indicative of the reliability of the current index values may be produced based on the input signals. The quality information may then be employed to give an indication of the current reliability of the index and a warning if the reliability of the diagnostic index becomes compromised.
