Carbapenem Resistance in Palliative Care Units

Abstract

The need for palliative care units is increasing every year due to the aging world population. In such units, infections can reach life-threatening levels due to the comorbidities of patients. This study aimed to investigate the change in carbapenem resistance in infections in palliative care units over the years in order to help determine empirical treatment approaches. Microbiological data of patients hospitalized in palliative care units between May 2021 and May 2024 were retrospectively analyzed. Isolates were identified conventionally and with an automated system on BD Phoenix M50 (Becton Dickinson, Maryland, USA). Ceftazidime-avibactam (CZA) susceptibility was analyzed in multidrug-resistant isolates. Carbapenem resistance was detected in 311 of the 630 samples sent to our laboratory. The rate of carbapenem resistance decreased from 56.7% to 45.1% between May 2021 and May 2024, especially in Klebsiella pneumoniae and Escherichia coli. However, a significant increase was observed in Pseudomonas aeruginosa. The majority of carbapenem-resistant isolates were found in urine samples. In the A. baumannii strains, no change in carbapenem resistance was observed over the years. The CZA resistance rates were 15.6% in P. aeruginosa, 12.5% in E. coli, and 2.5% in K. pneumoniae. The colistin resistance rates were 18.5% in K. pneumoniae and 1% in A. baumannii. Colistin resistance was not detected in the E. coli and P. aeruginosa strains. Due to increasing resistance rates, identifying and monitoring carbapenemase-producing isolates has become important for effective treatment selection for patients hospitalized in palliative care wards and for the successful implementation of infection-control measures in hospital settings, especially among geriatric patients. Such studies will allow health-care staff to provide patients with the right treatment and care and compare the data for Türkiye with those from other countries. Our results show that colistin and CZA are successful treatment options against carbapenem-resistant isolates.
