Abstract

Objectives: We had for aim to determine the characteristics of carbapenemase-producing enterobacteria (CPE) carriers and to assess the economic impact of isolation measures leading to loss of activity (closed beds, prolonged hospital stays) and additional personnel hours.

Patients and methods: We conducted a retrospective study for 2years (2012/2013), in a French general hospital, focusing on CPE carriers with clinical case description. The costs were estimated by comparing the activity of concerned units (excluding the ICU) during periods with CPE carriers or contacts, during the same periods of the year (n-1), plus additional hours and rectal swabs.

Results: Sixteen EPC carriers were identified: 10 men and 6 women, 65±10years of age. Seven patients acquired EPC in hospital during 2 outbreaks in 2012. Four patients presented with an infection (peritonitis, catheter infection, and 2 cases of obstructive pyelonephritis) with a favorable outcome. The median length of stay was 21days [4,150]. Six patients died, 1 death was indirectly due to CPE because of inappropriate empiric antibiotic therapy. A decrease in activity was observed compared to the previous year with an estimated 547,303€ loss. The 1779 additional hours cost 63,870€, and 716 screening samples cost 30,931€. The total additional cost was estimated at 642,104€ for the institution.

Conclusions: Specialized teams for CPE carriers and isolation of contact patients, required to avoid/control epidemics, have an important additional cost. An appreciation of their support is needed, as well as participation of rehabilitation units.
