Antimicrobial use and misuse at the end of life: a retrospective analysis of a treatment escalation/limitation plan

BACKGROUND: Antimicrobial treatment is common at end of life. A treatment escalation/limitation plan (TELP) offers the opportunity to avoid non-beneficial treatment in critically ill patients. Our aim was to evaluate antimicrobial prescribing in terminally ill patients, and assess whether it was modified using a TELP. METHODS: Appropriateness of antimicrobial treatment was audited using a priori criteria in 94 consecutive hospital deaths. Prescribing in patients whose death was expected/unexpected, and who had a TELP with/without a 'ceiling' for antimicrobials, were compared. RESULTS: Twenty three of 94 patients (24.5%) were receiving antimicrobials at time of death. This was not influenced by evidence of infection or whether death was expected. The use of a TELP (n = 81) with an antimicrobial 'ceiling' (28 with, 53 without) was associated with a significant reduction in antimicrobials administered (28.6% vs 81.1%; p < 0.0005). CONCLUSIONS: Many complex factors contribute to antimicrobial misuse at end of life. An appropriately constructed TELP reduces inappropriate prescribing.
