Abstract

A computer-implemented system and method of evaluating the effects of medical treatments, the method including receiving patient record data; identifying relevant characteristics for evaluation; identifying a first treatment; identifying a second treatment; assigning a weight to each patient case; determining the relative likelihood, using the assigned weights, that an identified treatment will result in an identified effect when contrasted with a second identified treatment; and, outputting this estimated relative likelihood.

Claims

1. A computer-implemented method of evaluating the effects of medical treatments comprising:

receiving patient record data;

identifying relevant characteristics for evaluation;

identifying a first treatment;

identifying a second treatment;

assigning a weight to each patient case;

determining the relative likelihood, using the assigned weights, that an identified treatment will result in an identified effect when contrasted with a second identified treatment; and

,

outputting this estimated relative likelihood.

2. The method of claim 1, wherein the weight assigned to each patient case is based on the likelihood that the patent would be a member of the exposed group;

3. The method of claim 2, wherein the weight assigned to each patient case is calculated by matching the patients traits and combinations of traits to a target population.

4. The method of claim 3, wherein a regression is performed in determining the relative likelihood.

5. The method of claim 4, wherein a Poisson regression is performed.

6. The method of claim 5, wherein at least some of the traits matched are used as covariates in the regression.

7. A system for evaluating the effects of medical treatments comprising:

a network interface;

a patient record database residing on a server accessed through a network; and

a server for analysis, wherein the analysis server is configured to receive patient record data;

identify relevant characteristics for evaluation;

identify a first treatment;

identify a second treatment;

assign a weight to each patient case based on the likelihood that the patent would be a member of the exposed group;

deter mine the relative likelihood, using the assigned weights, that an identified treatment will result in an identified effect when contrasted with a second identified treatment; and

, output this estimated relative likelihood.

8. An analysis server for evaluating the effects of medical treatments comprising:

a processor; and

a memory operably coupled to the processor storing programming instructions therein, the processor being operable to execute program instructions, the program instructions including;

receiving patient record data;

identifying relevant characteristics for evaluation;

identifying a first treatment;

identifying a second treatment;

assigning a weight to each patient case based on the likelihood that the patent would be a member of the exposed group;

determining the relative likelihood, using the assigned weights, that an identified treatment will result in an identified effect when contrasted with a second identified treatment; and

,

outputting this estimated relative likelihood.
