No Growth Cultures
How do you keep a physician in suspense? Ask him or her to order a culture. In small labs where most routine cultures are urine, sputum, blood, and
surface wounds, there can be a daily battle between getting microbiology results in the hands of the docs when they need to treat the patients and getting the
rest of the lab work done. Techs in microbiology often don’t know when physicians need information about cultures.
For example, if a urine culture is ordered on a symptomatic patient but the physician prescribes antibiotics, he or she might wait to see what happens. If the
patient responds to treatment, the culture results are confirmatory. If not, there is a greater sense of urgency.
Blood cultures can generate more anxiety, particularly with septic patients, and a laboratory can receive multiple telephone calls asking about their status.
In some cases, cultures following treatment are important to know if an infection cleared. As with many cultures, there is no “one size fits all.”
Laboratories can use a number of strategies to deal with these issues, including giving physicians online access to unverified results, creating preliminary
reports, and telephoning prelims.
But no growth cultures, it seems to me, can be expedited most quickly. Urine cultures negative at 24 hours and blood cultures negative at 48 can be
finalized and quickly available with a comment that these cultures are held, reviewed for any growth, and amended reports issued as appropriate.
Consistently reporting these negative cultures at 24 and 48 hours builds an expectation in the rest of the team that can reduce anxiety and improve care.
Question is how?
Waiting for the morning review of cultures works for the laboratory, but of course all cultures aren’t plated or incubated in the morning. Since they arrive at
all times, some kind of alert system to read and result the negatives makes the most sense. Most lab information systems, for example, can generate
outstanding reports that can highlight overdue results.
