Oftentimes, an inpatient healthcare facility is reimbursed for treatment of patients based on a prospective payment system. As healthcare costs began to escalate, in 1983, the retrospective payment system for the Medicare program was replaced a prospective payment system. The prospective payment system pays for acute hospital care based on the expected costs, rather than accrued charges.
Each patient discharged from a hospital setting is categorized into a billing group called a Diagnosis Related Group (DRG). The International Classification of Diseases, Ninth Revision, and Clinical Modifications (ICD-9-CM) is used to implement the DRG prospective payment system. ICD-9-CM is a diagnostic dictionary allowing diseases, symptoms, health problems and procedures to be classified and coded. The coded data elements are utilized to determine the DRG for a patient. The inpatient facility is reimbursed a predetermined amount for all services, no matter the length of stay or amount of resources used by the patient. Thus, a given inpatient facility may be paid the same for a patient with congestive heart failure who has had an inpatient stay of three days and a patient with congestive heart failure who has stayed for five days consuming more resources.
Current systems do not determine the predicted length of stay for a patient when the patient is admitted or during the patient's stay. The systems also do not display the current length of stay for the patient along with a predicted length of stay. As such, caregivers and administrators cannot easily view which patients are nearing discharge or determine which patients may require an extended stay for which utilization review is needed based on a predicted length of stay.
In one embodiment, a computerized method for displaying a predicted length of stay and actual length of stay in an inpatient healthcare facility for a patient is provided. A predicted length of stay and an actual length of inpatient stay in a healthcare facility for a patient are accessed. The predicted length of stay and the actual length of inpatient stay for the patient are displayed concurrently.
In another embodiment, a user interface embodied on at least one computer readable medium for simultaneously displaying a predicted length of stay for a patient and an actual length of stay for a patient in an inpatient healthcare setting is provided. The user interface comprises a first display area configured to display a current length of stay for a patient in an inpatient healthcare facility and a second display area configured to display a predicted length of stay for the patient in the inpatient healthcare facility.
In yet another embodiment, a computerized method of determining a predicted length of stay in an inpatient healthcare facility for a patient is provided. Patient data for a current patient is received and historical data for previously treated patients is accessed. The patient data and historical data are utilized to determine a predicted length of inpatient stay for the patient and the predicted length of stay for the patient is displayed.
The present invention is described in detail below with reference to the attached drawing figures, wherein:
Embodiments of the present invention are directed to a system and method for utilizing predicted length of stay for a patient for workload balancing in accordance with embodiments of the present invention.

For example, the predictive modeling data may consider previously treated patients with the same ICD-9 codes that are of the same or similar age and region as the patient for which a predicted length of stay is being calculated. In another example, the predictive model may consider a wide variety of historical and current data in view of the available historical and current data for the patient and the desired objectives. For example, the time period for historical data used in the predictive model may be any time period, such as three months, six months and one year. The historical data used with the predictive model may be based on a specified region. The predictive model may also use ICD-9 codes of three, four and five digits depending on the available data.
The one or more predictive models may include a variety of statistical techniques for identifying a possible future outcome. Statistical techniques such as multiple algorithms, linear regression, partial least squares and logistic regression may be applied to stored historical data for a variety of patients. Based on the application of the predictive modeling data to the current clinical data of the patient, a predicted length of stay is calculated and stored for the patient at step 310. The predicted length of stay for the patient may be communicated or populated into a variety of databases, including a patient's electronic medical record 204 of

Displaying the predicted length of stay for a patient allows a case manager to view which patients may be ready for discharge and/or determine which patients may require an extended stay for which utilization review is needed. Displaying the actual length of stay and predicted length of stay for a patient will allow a case manager to use resources efficiently and increase productivity by focusing on the patients that require priority. As such, a patient can be moved through the healthcare system to reduce the chances of complications and infections. Care can be provided to a patient that is medically necessary for cost-effective treatment. As such, the patient receives the appropriate level of care and the healthcare facility is proper reimbursed for the treatment provided.
Referring again to
The alert may be delivered in a variety of ways including, by way of example only, an electronic mail message, adding the patient to a result queue to be viewed by a case manager, adding an alert icon or highlighting the difference of days in the case manager work list. With reference to
Returning to
At step 418, the new predicted length of stay is populated, communicated to or stored a database such as the patient's electronic medical record. In some embodiments, multiple predicted lengths of stay may be calculated for a patient during a patient's stay and each of them stored with time and date information so that they may be referred to at a later time. The recalculated predicted length of stay supercedes the current predicted length of stay for the patient, compared to the actual length of stay for the patient and displayed.
