ANALISI DI COSTO-EFFICACIA DELL’IMPIANTO E DELL’UTILIZZO DI PORTS PER CHEMIOTERAPIA IN PAZIENTI ADULTI. RISULTATI DI UN TRIAL CLINICO MONOCENTRICO RANDOMIZZATO. Roberto Biffi, MD,F SPS Direttore Divisione di Chirurgia Addomino-Pelvica e Mini-Invasiva Istituto Europeo di Oncologia, Milano ANALISI DI COSTO-EFFICACIA DELL’IMPIANTO E DELL’UTILIZZO DI PORTS PER CHEMIOTERAPIA IN PAZIENTI ADULTI Background and Rationale • Compelling evidence that real-time ultrasound (US) – guided central veins access is associated with a lower incidence of complications and a higher rate of success than landmark blind techniques. • Meta-analyses addressed the issue of cost-effectiveness of US guidance in short-term CVCs (Hind BMJ 2003; Calvert Anaesthesia 2004) • No randomized trials have so far investigated the costeffectiveness ratio of US guidance in long-term central venous access ports for oncology patients undergoing chemotherapy. ANALISI DI COSTO-EFFICACIA DELL’IMPIANTO E DELL’UTILIZZO DI PORTS PER CHEMIOTERAPIA IN PAZIENTI ADULTI Methods • 403 patients eligible for receiving i.v. chemotherapy for solid tumors were randomly assigned to implantation of a single type of port (Bard Port, Bard Inc., Salt Lake City, UT) through a percutaneous landmark access to the internal jugular, a USguided access to the axillary-subclavian or a cut-down access of the cephalic vein. • Procedural times and complications were prospectively recorded. • Costs were analytically calculated. 465 Assessed for elegibility Trial profile conforming to CONSORT guidelines 24 Refused to participate 38 Did not meet inclusion criteria 403 Randomized 134 internal jugular catheter 120 received foreseen insertion site 136 subclavian catheter 135 received foreseen insertion site 133 cephalic catheter 12 received foreseen insertion site 12 shifted to another arm 2 cancelled operation 1 shifted to another arm 21 shifted to another arm 2 Withdrew informed consent 13 Had no data available 1 Withdrew informed consent 12 Had no data available 117 Assessed for primary endpoint 123 Assessed for primary endpoint 2 Withdrew informed consent 11 Had no data available 120 Assessed for primary endpoint Roberto Biffi 2008 Roberto Biffi 2008 Failed attempts at insertion procedures, number of catheters shifted to another experimental group as defined by initial randomization, and final layout of catheters positioning by insertion sites.

ANALISI DI COSTO-EFFICACIA DELL’IMPIANTO E DELL’UTILIZZO DI PORTS PER CHEMIOTERAPIA IN PAZIENTI ADULTI Results-1 • No differences were found for early complication rate in the three groups (internal jugular: 0%, subclavian: 0%, cephalic: 1.5% ; p = 0.132). US-guided subclavian insertion site had significantly lower failures (P = 0.001). • Infections occurred in one, three and one patients (internal jugular, subclavian and cephalic access respectively, p = 0.464), whereas venous thrombosis was observed in 15, 8 and 11 patients (p = 0.272). • Mean procedural time was 38.2 min for the internal jugular, 33.7 for subclavian and 39.5 for cephalic vein (p = 0.0003). ANALISI DI COSTO-EFFICACIA DELL’IMPIANTO E DELL’UTILIZZO DI PORTS PER CHEMIOTERAPIA IN PAZIENTI ADULTI Results-2 • Overall mean cost for purchase, implantation, diagnosis and treatment of early and late complications in each patient was: • 2084 Euros for internal jugular • 1934 Euros for US-guided subclavian • 2122 Euros for cephalic vein (p = 0.0001 ) . ANALISI DI COSTO-EFFICACIA DELL’IMPIANTO E DELL’UTILIZZO DI PORTS PER CHEMIOTERAPIA IN PAZIENTI ADULTI Limitations • Single institution data • Costs of materials and diagnostics might differ from those gathered at other centres • Doctors and nurses honoraria might not apply to most practitioners elsewhere • High case-load and experience might impact the complications’ rate ANALISI DI COSTO-EFFICACIA DELL’IMPIANTO E DELL’UTILIZZO DI PORTS PER CHEMIOTERAPIA IN PAZIENTI ADULTI Some data about costs from the literature…..* Author Institution / Country Cost Charge Biffi et al 1998 IEO Milano / Italy 1591 USD NR Bow et al 1999 University of Manitoba / Canada 1988 CAD 2005 USD NR Schuld et al 2009 University of Hamburg / Germany 400.72 EUR local 484.86 EUR general NR Sticca et al 2009 University of North Dakota / USA NR 5,301 USD IR 4,543 USD Surg University of Toronto / Canada 20,762 CAD I.R. 20,900 CAD Surg.
