Cost-effectiveness Analysis of Peripherally Inserted Central Catheters Versus Central Venous Catheters for in-Hospital Parenteral Nutrition.

OBJECTIVE: Our objective was to evaluate the cost-effectiveness of the use of peripherally inserted central venous catheters (PICCs) by a vascular access team (VAT) versus central venous catheters (CVCs) for in-hospital total parenteral nutrition (TPN). METHODS: The study used a cost-effectiveness analysis based on observational data retrospectively obtained from electronic medical records from 2018 to 2019 in a teaching hospital. We included all interventional procedures requiring PICCs or CVCs with the indication of TPN. We recorded the costs of insertion, maintenance, removal, and complications. The main outcome measure was the incidence rate of catheter-associated bacteremia per 1000 catheter days. Cost-effectiveness analysis was performed from the hospital perspective within the context of the publicly funded Spanish health system. Confidence intervals for costs and effectiveness differences were calculated using bootstrap methods. RESULTS: We analyzed 233 CVCs and 292 PICCs from patients receiving TPN. Average duration was longer for PICC (13 versus 9.4 days, P < 0.001). The main reason for complications in both groups was suspected infection (9.77% CVC versus 5.18% PICC). Complication rates due to bacteremia were 2.44% for CVC and 1.15% for PICC. The difference in the incidence of bacteremia per 1000 catheter days was 1.29 (95% confidence interval, -0.89 to 3.90). Overall, costs were lower for PICCs than for CVCs: the difference in mean overall costs was -€559.9 (95% confidence interval, -€919.9 to -€225.4). Uncertainty analysis showed 86.37% of results with lower costs and higher effectiveness for PICC versus CVC. CONCLUSIONS: Placement of PICC by VAT compared with CVC for TPN reduces costs and may decrease the rate of bacteremia.

First Cases of Natural Infections with Borrelia hispanica in Two Dogs and a Cat from Europe.

Canine cases of relapsing fever (RF) borreliosis have been described in Israel and the USA, where two RF species, Borrelia turicatae and Borrelia hermsii, can cause similar clinical signs to the Borrelia persica in dogs and cats reported from Israel, including fever, lethargy, anorexia, thrombocytopenia, and spirochetemia. In this report, we describe the first clinical cases of two dogs and a cat from Spain (Cordoba, Valencia, and Seville) caused by the RF species Borrelia hispanica. Spirochetes were present in the blood smears of all three animals, and clinical signs included lethargy, pale mucosa, anorexia, cachexia, or mild abdominal respiration. Laboratory findings, like thrombocytopenia in both dogs, may have been caused by co-infecting pathogens (i.e., Babesia vogeli, confirmed in one dog). Anemia was noticed in one of the dogs and in the cat. Borrelia hispanica was confirmed as an infecting agent by molecular analysis of the 16S rRNA locus. Molecular analysis of housekeeping genes and phylogenetic analyses, as well as successful in vitro culture of the feline isolate confirmed the causative agent as B. hispanica.
