by a processor:

receiving, from a user, information specifying the local medical rule associated with an initial sub-population and sharing instructions that specify other users that can access the local medical rule;

iteratively:

applying the local medical rule to one or more additional sub-populations without sharing Protected Health Information (PHI) associated with the initial sub-population, wherein the one or more additional sub-populations are associated with at least some of the other users;

aggregating results associated with the local medical rule for the one or more additional sub-populations; and

generating the population-based medical rule by modifying the local medical rule based on the aggregated results and one or more quality metrics; and

after generating the population-based medical rule, selectively providing the population-based medical rule to the user without sharing PHI associated with the one or more additional sub-populations.

providing, to the other users, notifications about the local medical rule in response to the sharing instructions; and

in response to receiving an opt-in instruction from one of the other users, including a particular sub-population in the one or more additional sub-populations.

wherein the method further comprises, when an editing instruction for the population-based medical rule is received from another user, retroactively applying the revised population-based medical rule to medical records associated with at least one of: the initial sub-population, and the one or more additional sub-populations.

wherein the method further comprises:

when an editing instruction for the population-based medical rule is received from another user, prospectively applying the revised population-based medical rule during further clinical encounters with individuals in at least one of: the initial sub-population, and the one or more additional sub-populations; and

aggregating second results associated with the revised population-based medical rule; and

determining an updated population-based medical rule based on the aggregated second results and the one or more quality metrics.

receiving, from a user, information specifying the local medical rule associated with an initial sub-population and sharing instructions that specify other users that can access the local medical rule;

iteratively:

applying the local medical rule to one or more additional sub-populations without sharing Protected Health Information (PHI) associated with the initial sub-population, wherein the one or more additional sub-populations are associated with at least some of the other users;

aggregating results associated with the local medical rule for the one or more additional sub-populations; and

generating the population-based medical rule by modifying the local medical rule based on the aggregated results and one or more quality metrics; and

after generating the population-based medical rule, selectively providing the population-based medical rule to the user without sharing PHI associated with the one or more additional sub-populations.

wherein the retrospective analysis involves reanalyzing previously acquired measurements based on a stored measurement configuration that was used to acquire the measurements.

provide, to the other users, notifications about the local medical rule in response to the sharing instructions; and

in response to receiving an opt-in instruction from one of the other users, include a particular sub-population in the one or more additional sub-populations.

wherein executing the instructions further causes the computer system to, when an editing instruction for the population-based medical rule is received from another user, retroactively apply the revised population-based medical rule to medical records associated with at least one of: the initial sub-population, and the one or more additional sub-populations.

wherein executing the instructions further causes the computer system to:

when an editing instruction for the population-based medical rule is received from another user, prospectively apply the revised population-based medical rule during further clinical encounters with individuals in at least one of: the initial sub-population, and the one or more additional sub-populations; and

aggregate second results associated with the revised population-based medical rule; and

determine an updated population-based medical rule based on the aggregated second results and the one or more quality metrics.

a processor configured to execute a program module;

memory, coupled to the processor, configured to store instructions for dynamically generating a population-based medical rule via anonymous sharing of a local medical rule, wherein, when executed by the processor, the instructions cause the computer system to:

receive, from a user, information specifying the local medical rule associated with an initial sub-population and sharing instructions that specify other users that can access the local medical rule;

iteratively:

apply the local medical rule to one or more additional sub-populations without sharing Protected Health Information (PHI) associated with the initial sub-population, wherein the one or more additional sub-populations are associated with at least some of the other users;

aggregate results associated with the local medical rule for the one or more additional sub-populations; and

generate the population-based medical rule by modifying the local medical rule based on the aggregated results and one or more quality metrics; and

after generating the population-based medical rule, selectively providing the population-based medical rule to the user without sharing PHI associated with the one or more additional sub-populations.
