In-Hospital Costs and Costs of Complications of Chronic Total Occlusion Angioplasty: Insights From the OPEN-CTO Registry.

OBJECTIVES: The aim of this study was to describe the costs of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and the association of complications during CTO PCI with costs and length of stay (LOS). BACKGROUND: CTO PCI generally requires more procedural resources and carries higher risk for complications than PCI of non-CTO vessels. The costs of CTO PCI using the hybrid approach have not been described, and no studies have examined the impact of complications on in-hospital costs and LOS in this population. METHODS: Costs were calculated for 964 patients in the 12-center OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Hybrid Procedures) registry using prospectively collected resource utilization and billing data. Multivariate models were developed to estimate the incremental costs and LOS associated with complications. Attributable costs and LOS were calculated by multiplying the independent cost of each event by its frequency in the population. RESULTS: Mean costs for the index hospitalization were $17,048 ± 9,904; 14.5% of patients experienced at least 1 complication. Patients with complications had higher mean hospital costs (by $8,603) and LOS (by 1.5 days) than patients without complications. Seven complications were independently associated with increased costs and 6 with LOS; clinically significant perforation and myocardial infarction had the greatest attributable cost per patient. Overall, complications accounted for $911 per patient in hospital costs (5.3% of the total costs) and 0.2 days of additional LOS. CONCLUSIONS: Complications have a significant impact on both LOS and in-hospital costs for patients undergoing CTO PCI. Methods to identify high-risk patients and develop strategies to prevent complications may reduce CTO PCI costs.

Resource requirements and reduction in cardiac mortality from deep inspiration breath hold (DIBH) radiation therapy for left sided breast cancer patients: A prospective service development analysis.

INTRODUCTION: Use of deep inspiration breath hold (DIBH) radiation therapy may reduce long-term cardiac mortality. The resource and time commitments associated with DIBH are impediments to its widespread adoption. We report the dosimetric benefits, workforce requirements, and potential reduction in cardiac mortality when DIBH is used for left-sided breast cancers. METHODS AND MATERIALS: Data regarding the time consumed for planning and treating 50 patients with left-sided breast cancer with DIBH and 20 patients treated with free breathing (FB) radiation therapy were compiled prospectively for all personnel (regarding person-hours [PH]). A second plan was generated for all DIBH patients in the FB planning scan, which was then compared with the DIBH plan. Mortality reduction from use of DIBH was calculated using the years of life lost resulting from ischemic heart disease for Indians and the postulated reduction in risk of major cardiac events resulting from reduced cardiac dose. RESULTS: The median reduction in mean heart dose between the DIBH and FB plans was 166.7 cGy (interquartile range, 62.7-257.4). An extra 6.76 PH were required when implementing DIBH as compared with FB treatments. Approximately 3.57 PH were necessary per Gy of reduction in mean heart dose. The excess years of life lost from ischemic heart disease if DIBH was not done in was 0.95 per 100 patients, which translates into a saving of 12.8 hours of life saved per PH of work required for implementing DIBH. DIBH was cost effective with cost for implementation of DIBH for all left-sided breast cancers at 2.3 times the annual per capita gross domestic product. CONCLUSION: Although routine implementation of DIBH requires significant resource commitments, it seems to be worthwhile regarding the projected reductions in cardiac mortality.

Using a new evidence-based trauma protocol to improve detection and reduce costs in patients with blunt cardiac injury.

INTRODUCTION: Management of blunt cardiac injury is often discussed in trauma literature due to the lack of a "gold standard" for early identification and cost-effective care. The effectiveness of an evidence-based trauma protocol was assessed by comparing patients treated with the new protocol to those managed with prior practice. METHODS: The data of 80 patients prospectively managed using the new trauma protocol were compared with the medical records of 80 former patients treated according to existing practice. RESULTS: Implementing the new protocol improved detection of abnormal troponin I levels and resulted in cost savings. The length of time inpatients required continuous electrocardiographic monitoring decreased by 4.23 days and echocardiography use dropped by 70%. CONCLUSION: Implementation of the evidence-based trauma protocol at our facility improved the early identification of patients with blunt cardiac injury and reduced the number of laboratory and diagnostic tests.
