Cost-effectiveness of second-line diagnostic investigations in patients included in the DANTE trial: a randomized controlled trial of lung cancer screening with low-dose computed tomography.

AIM: The aim of this study was to analyze the economic efficiency of second-line diagnostic investigations in patients with undetermined lung nodules. PARTICIPANTS AND METHODS: A retrospective review of all surgical cases included in the DANTE trial from 2001 to 2006 for lung cancer screening was performed. Overall, 217 patients and 261 lung nodules were analyzed. The cohort was divided into patients investigated with PET and/or computed tomography (CT)-guided biopsy (PET-CTB protocol; N=100), compared with those assessed with serial low-dose CT scans (standard protocol; N=161). Outpatient's and inpatient's costs were expressed in euros and derived from the Italian National Health Service. Ineffective costs were defined as the cost of procedures that lead to avoidable surgical intervention. RESULTS: The diagnostic accuracy of the two protocols was 91% for the standard (sensitivity 100%, specificity 91%, positive predictive value 26%, and negative predictive value 100%) and 90% for the PET-CTB protocol (sensitivity 98%, specificity 81%, positive predictive value 85%, and negative predictive value 97%). Average costs for outpatient's diagnostics were 694 and 1.462 euros, respectively, for the standard and PET-CTB protocol. Average inpatient's costs for both protocols were 12.121 euros. The two protocols showed comparable effectiveness in terms of outpatient's costs (94 and 90%, respectively; P=0.252). Inpatient's costs were effective in 36% of cases monitored according to the standard protocol compared with 85% of patients investigated with PET-CTB protocol. Ineffective costs corresponded to 64 and 15%, respectively (P<0.0001). CONCLUSION: Despite a higher average cost for outpatient's diagnostics, the implementation of PET imaging with or without CT-guided needle biopsy in the workup of suspicious lung nodules results in reduced unnecessary harm and costs related to inpatient's procedures.

Improved patient blood management and cost saving in hip replacement surgery through the implementation of pre-operative Sucrosomial® iron supplementation: a quality improvement assessment study.

PURPOSE: To compare post-operative recovery of prosthetic hip surgery patients with or without the implementation of iron supplementation with a new highly absorbable oral iron formulation. METHODS: Observational retrospective quality improvement assessment conducted on patients who had undergone elective prosthetic hip surgery (first implant) with ferritin < 100 mcg/dl and Hb values between 13 and 14 g/dl for men and 12 g/dl and 13.5 g/dl for women, or having ferritin levels > 100 mcg/dl but C-reactive protein (CRP) > 3 mg/l and transferrin saturation (TSAT) < 20%, which together are suggestive of functional iron deficiency. The analysis compared a group of non-anaemic patients having ferritin levels > 100 mcg/l to two groups of patients with iron deficiency, of which only one received iron supplementation. Measurements included haemoglobin levels, length of hospital stay, and number of transfused patients/blood units. RESULTS: Patients with iron deficiency supplemented with Sideral® Forte compared to non-supplemented patients showed a smaller decline in post-operative Hb (9.7 ± 1.24 g/dl vs 8.4 ± 0.6 g/dl), required shorter hospital stay (4 vs 6.5 days) and less blood transfusions (0 in the iron-supplemented group vs 7 units in the non-iron-supplemented group), yielding an overall savings of 1763.25 €/patient. CONCLUSIONS: Pre-operative sucrosomial iron supplementation at least 4 weeks prior to elective surgery in non-anaemic patients limits the drop in post-operative Hb levels, determining higher post-operative haemoglobin, quicker post-surgical recovery, shorter hospitalisation, and decreased surgery-related costs.

Incidence and cost of perioperative red blood cell transfusion for elective spine fusion in a high-volume center for spine surgery.

BACKGROUND: Spine fusion is a surgical procedure characterized by a significant perioperative bleeding, which often requires red blood cell (RBC) transfusion. METHODS: The incidence and the cost of RBC transfusion were evaluated in all patients undergoing elective surgery for spine fusion in our Institution, a high-volume center for spine surgery, over a period of 3 years. The analysis specifically addressed the RBC transfusion need in all the different spine fusion procedures (atlanto-axial, cervical, dorsal, lumbar, revisions) with the different surgical approaches (anterior, posterior). RESULTS: During the 3 years of observation, a total of 1.882 elective spine fusions were performed. More than half of the procedures (n = 964) were posterior lumbar fusions. Overall, 5% of the patients (n = 103) required RBC transfusion. The cervical fusions were the procedures with the lowest percentage of RBC need (0-5%), while the dorsal and the lumbar ones, with the anterior approach, represented the procedures with the highest rate of transfusion (29% and 25% respectively). More than 60 % of the RBC units were employed in the instance of posterior lumbar fusion, while a variable 1-10% of the units was used in each of the other procedures. The overall transfusion cost was of 46.000 euros, with a distribution of costs that paralleled the amount of units transfused for each procedure. CONCLUSIONS: Several surgical and patient factors may contribute to the perioperative blood loss. An accurate patient blood management, may efficiently decrease transfusion requirements and ultimately healthcare costs.

Red Blood Cell Transfusion Need for Elective Primary Posterior Lumbar Fusion in A High-Volume Center for Spine Surgery.

(1) Background: This study evaluated the perioperative red blood cell (RBC) transfusion need and determined predictors for transfusion in patients undergoing elective primary lumbar posterior spine fusion in a high-volume center for spine surgery. (2) Methods: Data from all patients undergoing spine surgery between 1 January 2014 and 31 December 2016 were reviewed. Patients' demographics and comorbidities, perioperative laboratory results, and operative time were analyzed in relation to RBC transfusion. Multivariate logistic regression analysis was performed to identify the predictors of transfusion. (3) Results: A total of 874 elective surgeries for primary spine fusion were performed over the three years. Only 54 cases (6%) required RBC transfusion. Compared to the non-transfused patients, transfused patients were mainly female (p = 0.0008), significantly older, with a higher ASA grade (p = 0.0002), and with lower pre-surgery hemoglobin (HB) level and hematocrit (p < 0.0001). In the multivariate logistic regression, a lower pre-surgery HB (OR (95% CI) 2.84 (2.11-3.82)), a higher ASA class (1.77 (1.03-3.05)) and a longer operative time (1.02 (1.01-1.02)) were independently associated with RBC transfusion. (4) Conclusions: In the instance of elective surgery for primary posterior lumbar fusion in a high-volume center for spine surgery, the need for RBC transfusion is low. Factors anticipating transfusion should be taken into consideration in the patient's pre-surgery preparation.
