Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing implants for surgical procedures. In some implementations, a model that has been trained using data indicating characteristics of other patients and items used in surgeries for the other patients is obtained. Using the model and patient characteristics for a patient, such as the height and weight of the patient, the items needed for a surgery for a particular patient can be identified. For example, the likelihoods that different sizes of an implant component will be needed can be identified and used to determine which sizes of components should be provided at a medical facility and in the operating room for the patient's surgery.

First claim

What is claimed is:

1. A method for providing automated predictions of quantities of implant components of different sizes to facilitate automated inventory management, the method being performed by one or more computers of a server system, the method comprising:
receiving, by the one or more computers of the server system, patient data over a communication network from one or more computers associated with a medical facility or one or more computers associated with one or more physicians, the patient data comprising data from electronic patient records;
accessing, by the one or more computers of the server system, data indicating (i) multiple scheduled orthopaedic surgeries that are scheduled to be performed at a particular medical facility during a particular future period of time, and (ii) physical patient characteristics for patients corresponding to the scheduled orthopaedic surgeries, the physical patient characteristics including at least a height of each of the patients and a weight of each of the patients; for each particular scheduled orthopaedic surgery of the scheduled orthopaedic surgeries: identifying, by the one or more computers of the server system, an implant component that is used during surgeries having a surgery type corresponding to the particular scheduled orthopaedic surgery;
identifying, by the one or more computers of the server system and from among a set of multiple models corresponding to different implant components, one or more models corresponding to the identified implant component, the one or more models having been generated using relationships between items used in past surgeries for other patients and physical characteristics including heights and weights of the other patients, the one or more models indicating correlations between (i) physical patient characteristics including at least height and weight and (ii) multiple different sizes of the implant component; and
generating, by the one or more computers of the server system and based on the height and the weight of the patient corresponding to the particular scheduled orthopaedic surgery, probability measures for multiple different sizes of the implant component using the identified one or more models, each of the probability measures indicating a probability that a particular size of implant component will be used in the particular scheduled orthopaedic surgery;
predicting, by the one or more computers of the server system and based on an aggregated set of probability measures generated for the scheduled procedures, a quantity of each of multiple different sizes of multiple different implant components to provide at the particular medical facility for the particular future period of time;
providing, by the one or more computers of the server system and prior to the particular time period, prediction data to the one or more computers associated with the medical facility over the communication network, the prediction data indicating the predicted quantity for each of the multiple different sizes of the multiple different implant components; and
automatically performing, by the one or more computers of the server system, one or more actions to adjust an inventory level for one or more of the multiple different sizes of the multiple different implant components based on the predicted quantity.

2. The method of claim 1 , wherein predicting the quantity of implant components comprises:
identifying, by the one or more computers of the server system, a predetermined confidence level representing a desired level of confidence that implant components needed for the scheduled orthopaedic surgeries will be available at the particular medical facility; and
for at least a first implant component of the one or more implant components, determining, by the one or more computers of the server system, based on the aggregated sets of probability measures, quantities of the first implant component to provide at the medical facility in each of the multiple different sizes to achieve the predetermined confidence level.

3. The method of claim 1 , further comprising:
accessing, by the one or more computers of the server system, records indicating an inventory of implant components at the particular medical facility;
comparing, by the one or more computers of the server system, (i) the predicted quantities of implant components of the multiple different sizes with (ii) recorded quantities of implant components of the in the inventory at the particular medical facility as indicated in the accessed records;
determining, by the one or more computers of the server system, based on the comparison, a difference between the predicted quantities of implant components and the recorded quantities of implant components; and
in response to determining the difference, providing, by the one or more computers of the server system, to the medical facility, a message indicating the difference between the predicted quantities of implant components and the recorded quantities of implant components.

4. The method of claim 3 , wherein the one or more actions to adjust an inventory level, based on determining the difference between the determined predicted quantities of implant components and the recorded quantities of implant components, comprise adjusting, by the one or more computers of the server system, the inventory of the particular medical facility by initiating or expediting one or more deliveries of implant components to the particular medical facility, wherein the one or more deliveries increase the amount available at the particular medical facility during the particular future period of time for each size of at least one implant component to the predicted quantities for each size of the at least one implant component.

5. The method of claim 1 , wherein providing the prediction data comprises:
providing, by the one or more computers of the server system, a web page to the one or more computers associated with the medical facility, the web page indicating the prediction data; or
providing, by the one or more computers of the server system, the prediction data to the one or more computers associated with the medical facility for display on an interface of a web-based application.

6. The method of claim 1 , wherein the scheduled orthopaedic surgeries comprise joint arthroplasty surgeries for a particular joint; and
wherein determining a quantity of each of multiple different sizes of multiple different implant components comprises determining, by the one or more computers of the server system, a quantity for each of multiple sizes of each of multiple different implant components that, when assembled, form a prosthesis for the particular joint.

7. The method of claim 1 , wherein generating probability measures for multiple different sizes of the implant component using the identified one or more models comprises:
generating, by the one or more computers of the server system, based on the height of the particular patient and the weight of the particular patient, first probability measures corresponding to different sizes of a first implant component used in orthopaedic surgeries of the particular orthopaedic surgery type using a first model; and
generating, by the one or more computers of the server system, based on the height of the particular patient, the weight of the particular patient, and the probability measures generated using the first model, second probability measures corresponding to different sizes of a second implant component that is used together with the first implant component in orthopaedic surgeries of the particular orthopaedic surgery type using a second model.

8. The method of claim 1 , wherein generating probability measures for multiple different sizes of the implant compon
