Definitions

  • the present invention relates generally to devices and methods for improving the delivery of patient care to patients, and more particularly, but not by way of limitation to devices and methods for improving the delivery of patient care to patients wherein patient information relating to a selected patient is obtained at a local facility system and is automatically transmitted to a regional facility system in response to a first patient recommendation signal indicating that the selected patient would benefit from immediate patient care.
  • Diabetic retinopathy is an insidious disease which if left untreated may cause blindness or serious vision loss. Because diabetic retinopathy does not cause pain or a change in the appearance of an afflicted individual's eye, diabetics afflicted with diabetic retinopathy are typically unaware of a condition that threatens their vision. About 40,000 of the sixteen million diabetics in the United States may go blind each year because of unsuspected and untreated diabetic retinopathy.
  • diabetics Although not all of these 40,000 diabetics can be effectively treated to prevent blindness even with regular screening eye exams, we estimate that blindness could be prevented in about 50% of these 40,000 diabetics if all of such diabetics were regularly screened for diabetic retinopathy. It should be noted that most general physicians are either untrained or lack the necessary equipment to detect diabetic retinopathy through an eye exam. Thus, diabetics must typically be examined by an optometrist or an ophthalmologist, some of whom are retinal specialists, on a regular basis so that diabetic retinopathy can be detected in its early stages.
  • diabetics there are many barriers to health care such as time, money, and convenience which prevent diabetics from receiving regular screening eye-exams.
  • ophthalmologists and retinal specialists are typically located in urban areas while diabetics are located in both urban areas and rural areas.
  • diabetics must have a separate appointment with an optometrist or ophthalmologist to have their eyes examined, and a separate appointment with a nephrologist for kidney evaluation, and a separate appointment with a podiatrist to have their feet examined, and a separate appointment with a neurologist to have their nervous system examined, etc.
  • This creates problems for both the diabetic patient and the health care providers in that it is inconvenient for the diabetic patient and difficult for each of the health care providers to keep each other informed. For these and possibly other reasons It has been estimated that only about 50% of diabetics participate in regular screening eye exams. In addition to the loss of sight of diabetics, unsuspected and untreated diabetic retinopathy is also costly to society.

  • the database 46 is updated so that the experiences, treatment recommendations and progress of the selected patient can be used to provide predictive probabilities for other patients.
  • the updated database 46 is utilized by the disease management logic module 40 to compute or build a second array of relative risk factors which are generally predictive of the progression of the patient condition or disease of a patient.
  • the disease management logic module 40 utilizes the second array of relative risk factors, the disease stage assigned by the data analysis system 38 and the clinical data contained in the fourth patient information signal to assign a second predictive probability to the selected patient in a similar manner as the first predictive probability was assigned to the selected patient as hereinbefore described.
  • the second predictive probability indicates whether or not the selected patient is inflicted with the patient condition, and if the selected patient is inflicted with the patient condition, the second predictive probability also indicates the probability that the patient condition of the selected patient will advance or progress to a higher disease stage (e.g., from class 1 to class 2) within a relatively short period of time.
  • a higher disease stage e.g., from class 1 to class 2
  • the disease management logic module 40 matches or compares the selected patient's patient characteristics (the disease stage assigned to the selected patient by the data analysis system 38 and the clinical data relating to the selected patient) with a population of patients (whose information is contained in the database) that share substantially similar patient characteristics to provide an indication (the second predictive probability) of the probability of the disease progression of the patient condition of the selected patient.
  • the disease management logic module 40 then generates a second patient recommendation signal based on the second predictive probability in a similar manner as the first patient recommendation signal was generated, as hereinbefore described. That is, the second patient recommendation signal provides a predictive model of a preferred or recommended treatment for the selected patient's patient condition. It should be noted that optimal treatment recommendations will be generated in the second patient recommendation signal by the disease management logic module 40 based on linking disease management logic module optimal management options with the cost of those options through predictive cost models.
  • the second patient recommendation signal typically includes the disease stage assigned by the data analysis system 38 and the second predictive probability.
  • the predictive model of the second patient recommendation signal is in the form of a recommended timed schedule which indicates whether or not the selected patient would benefit from immediate patient care (medical intervention) or would not benefit from immediate patient care.
  • the second patient recommendation signal will indicate that the selected patient would benefit from immediate patient care, such as laser photocoagulation surgery, via a recommended schedule.
  • the second patient recommendation schedule will indicate that an appointment needs to be scheduled for the selected patient at one of the regional treatment centers .
  • the second patient recommendation signal will indicate that the selected patient would not benefit from immediate patient care (surgery, for example) but needs to be screened again via a predetermined time schedule of every three months, for example. In this case, the second patient recommendation signal will indicate that an appointment needs to be scheduled for the selected patient to present again at the local facility system 12 within the predetermined time.
  • the disease management logic module 40 transmits the second patient recommendation signal to the central computer 36 via a signal path 72.
  • the central computer 36 receives the second patient recommendation signal, and in response thereto, the central computer 36 transmits the second patient recommendation signal to the local computer 18.
  • the local computer 18 receives the second patient recommendation signal, and in response thereto, the local computer 18 outputs the second patient recommendation signal to the output device 24 so that the second patient recommendation signal is perceivable by a patient care provider.

Abstract

La présente invention concerne un procédé destiné à améliorer l'administration de soins à des patients. Un premier signal de données constitué de données multimédia indiquant l'état d'un patient particulier est saisi dans un ordinateur local. Des données cliniques, des données de coût et des données administratives relatives à la santé du patient particulier sont également saisies dans l'ordinateur local. Le premier signal de données est combiné aux données cliniques, aux données de coût et aux données administratives pour former un premier signal d'information du patient lequel est transmis à un ordinateur central. Un stade prédéterminé de maladies est alors affecté au patient particulier sur la base du premier signal de données. Le stade de la maladie est combiné au premier signal d'information du patient pour former un second signal d'information du patient. Ensuite, un premier ensemble de facteurs de risques est calculé à partir d'une base de données contenant une pluralité de dossiers d'information de patients individualisées obtenus antérieurement.
