Utilizing time-to-positivity to generate treatment recommendations

One or more non-transitory computer-storage media having computer-executable instructions embodied thereon that, when executed, cause one or more computing devices to perform a method for utilizing a time-to-positivity associated with a blood culture to generate treatment recommendations, the method comprising:

• receiving an indication that the blood culture is inoculated and an indication of a first time, the first time corresponding to a time at which the blood culture is inoculated;
• receiving an indication that the blood culture is received by a positivity-detecting instrument and an indication of a second time, the second time corresponding to a time at which the blood culture is received by the positivity-detecting instrument;
• receiving, directly from the positivity-detecting instrument, a third time, the third time indicating a time at which an indication that the blood culture is positive for a presence of a bacterium is received by the positivity-detecting instrument;
• automatically determining a first time-to-positivity for the presence of the bacterium associated with the blood culture, wherein the first time-to-positivity is at least one of a difference between the third time and the first time or a difference between the third time and the second time;
• and
• automatically generating at least two treatment recommendations as a first subset of a plurality of treatment recommendations based on the first time-to-positivity, wherein the plurality of treatment recommendations is associated with the first time-to-positivity and wherein the first subset of the plurality of treatment recommendations based on the first time-to-positivity is different from a second subset of the plurality of treatment recommendations based on a second time-to-positivity that is different from the first time-to-positivity.

A computing system comprising:

• one or more processors;
• and
• computer storage memory having stored thereon computer-executable instructions that, when executed by the one or more processors, implement a method comprising:
• receiving, directly from a positivity-detecting instrument, an indication that a blood culture is positive for a presence of a bacterium,
• determining a quantity of time associated with generating the indication that the blood culture is positive for the presence of the bacterium, the quantity of time comprising a first time-to-positivity, and
• based on the first time-to-positivity, automatically generating at least two treatment recommendations as a first subset of a plurality of treatment recommendations, wherein the first subset of the plurality of treatment recommendations is different from a second subset of the plurality of treatment recommendations, the second subset based on a second time-to-positivity that is different from the first time-to-positivity.
