generate an electronic representation of the secondary patient population from the primary patient population based on the target number of patients and the at least one characteristic.

9 . The system of claim 8 , further comprising means for generating the electronic representation of the secondary patient population.

10 . The system of claim 8 , wherein the processor is further configured to:

iteratively generate the electronic representation of the secondary patient population from the primary patient population based on:

the target number of patients and the at least one characteristic,

a determination of a deviation of the secondary patient population from the target secondary patient population based on the target number of patients and the characteristic, and

an electronic representation of at least one additional patient from the primary patient population or the first data store based on the deviation.

11 . The system of claim 8 , wherein the processor is further configured to:

receive a provider characteristic;

access a second data store to obtain data records corresponding to one or more providers based on the provider characteristic; and

select at least one provider based on the data records.

12 . The system of claim 11 , wherein the processor is further configured to:

access a third data store to obtain data records associated with one or more investigators;

determine an association between the selected provider and at least one of the one or more investigators; and

select at least one investigator based on the association.

13 . The system of claim 11 , wherein the processor is further configured to determine an association between one or more patients and the at least one selected provider.

14 . The system of claim 8 , wherein the processor is further configured to:

receive an index event and a second event associated with the index event;

receive a time period, the time period associated with a difference in time between the index event and the second event;

and wherein the processor is further configured to obtain the electronic representation of the primary patient population based on EHRs associated with patients, the EHRs indicating occurrence of the index event and the second event, the second event occurring within the time period based on the index event.

15 . A computer-readable medium comprising program code for causing an electronic processor to execute a method, the program code comprising:

program code for obtaining an electronic representation of a primary patient population within a first data store, the primary patient population comprising a plurality of EHRs;

program code for receiving an electronic representation of a target secondary patient population, the target secondary patient population comprising a target number of patients and at least one characteristic; and

program code for generating an electronic representation of the secondary patient population from the primary patient population based on the target number of patients and the at least one characteristic.

16 . The computer-readable medium of claim 15 , wherein the program code for generating the electronic representation of the secondary patient population from the primary patient population comprises program code for using a means for generating the electronic representation of the secondary patient population.

17 . The computer-readable medium of claim 15 , wherein program code for generating the electronic representation of the secondary patient population comprises program code for iteratively generating an electronic representation of the secondary patient population from the primary patient population based on the target number of patients and the at least one characteristic, comprising:

program code for determining a deviation of the secondary patient population from the target secondary patient population based on the target number of patients and the characteristic; and

program code for obtaining an electronic representation of at least one additional patient for the secondary patient population from the primary patient population or the first data store based on the deviation.

18 . The computer-readable medium of claim 15 , further comprising:

program code for receiving a provider characteristic;
