The sample swap discovered after two reports were delivered

Lo scambio di provette scoperto dopo due referti consegnati · Healthcare · Beginner

The case

You direct a clinical laboratory. An internal plausibility check surfaces the unthinkable: on Tuesday, two tubes were swapped at check-in: two patients received each other's reports. One of the two reports contained markers compatible with a serious condition: the patient who received it by mistake has probably started a path of anxiety and follow-ups, while the patient it really belonged to received a reassuring report that was not his, and may not investigate what should be investigated. Forty-eight hours have passed. The reports are signed, the treating physicians may have already read them. What do you do, in what order, and what changes in the laboratory?

Dirigi un laboratorio analisi. Un controllo interno di plausibilità fa emergere l'impensabile: martedì, due provette sono state scambiate in fase di accettazione: due pazienti hanno ricevuto il referto dell'altro. Uno dei due referti conteneva marcatori compatibili con una patologia seria: il paziente che l'ha ricevuto per errore ha probabilmente iniziato un percorso d'ansia e approfondimenti, mentre il paziente a cui apparteneva davvero ha ricevuto un referto rassicurante che non era il suo, e potrebbe non approfondire ciò che andrebbe approfondito. Sono passate 48 ore. I referti sono firmati, i medici curanti li hanno forse già letti. Cosa fai, in che ordine, e cosa cambia nel laboratorio?
