CTO PCI carries low risk for procedural complications despite high success rates.

BackgroundLymphedema is a common complication of cancer therapeutics; its prevalence, treatment outcomes, and costs have been poorly defined. The objective of this study was to examine lymphedema prevalence among cancer survivors and to characterize changes in clinical outcomes and costs associated with a defined therapeutic intervention (use of a pneumatic compression devices [PCD]) in a representative, privately insured population.Methods and FindingsRetrospective analysis of de-identified health claims data from a large national insurer for calendar years 2007 through 2013. Patients were required to have 12 months of continuous insurance coverage prior to PCD receipt (baseline), as well as a 12-month follow-up period. Analyses were performed for individuals with cancer-related lymphedema (n = 1,065). Lymphedema prevalence was calculated: number of patients with a lymphedema claim in a calendar year divided by total number of enrollees. The impact of PCD use was evaluated by comparing rates of a pre-specified set of health outcomes and costs for the 12 months before and after, respectively, PCD receipt. Lymphedema prevalence among cancer survivors increased from 0.95% in 2007 to 1.24% in 2013. PCD use was associated with decreases in rates of hospitalizations (45% to 32%, p<0.0001), outpatient hospital visits (95% to 90%, p<0.0001), cellulitis diagnoses (28% to 22%, p = 0.003), and physical therapy use (50% to 41%, p<0.0001). The average baseline health care costs were high ($53,422) but decreased in the year after PCD acquisition (−$11,833, p<0.0001).ConclusionsLymphedema is a prevalent medical condition that is often a defining attribute of cancer survivorship. The problem is associated with high health care costs; Treatment (in this instance, use of PCD) is associated with significant decreases in adverse clinical outcomes and costs.

In selected patients undergoing largely elective PCI, same-day discharge was associated with a low rate of major complications and appeared to be as safe as routine overnight observation.

Background Multiple modern Indian hospitals operate at very low cost while meeting US-equivalent quality accreditation standards. Though US hospitals face intensifying pressure to lower their cost, including proposals to extend Medicare payment rates to all admissions, the transferability of Indian hospitals' cost advantages to US peers remains unclear.Methods Using time-driven activity-based costing methods, we estimate the average cost of personnel and space for an elective coronary artery bypass graft (CABG) surgery at two American hospitals and one Indian hospital (NH). All three hospitals are Joint Commission accredited and have reputations for use of modern performance management methods. Our case study applies several analytic steps to distinguish transferable from non-transferable sources of NH's cost savings.Results After removing non-transferable sources of efficiency, NH's residual cost advantage primarily rests on shifting tasks to less-credentialed and/or less-experienced personnel who are supervised by highly-skilled personnel when perceived risk of complications is low. NH's high annual CABG volume facilitates such supervised work "downshifting." The study is subject to limitations inherent in case studies, does not account for the younger age of NH's patients, or capture savings attributable to NH's negligible frequency of re-admission or post-acute care facility placement.Conclusions Most transferable bases for a modern Indian hospital's cost advantage would require more flexible American states' hospital and health professional licensing regulations, greater family participation in inpatient care, and stronger support by hospital executives and clinicians for substantially lowering the cost of care via regionalization of complex surgeries and weekend use of costly operating rooms.

T he incidence of periprocedural myocardial infarction (MI) after percutaneous coronary intervention (PCI) ranges from 2% to 50%, depending on the clinical presentation, type of procedure, choice of biomarker (creatine kinase [CK]-MB or troponin), and the threshold used to qualify the diagnosis. 1 Because of this heterogeneity of definition, the prognostic implications of periprocedural MI are controversial. However, several studies have demonstrated that periprocedural MI is associated with worse in-hospital, short-term, and long-term clinical outcomes, including death, recurrent MI, and need for revascularization. [3][4][5] Various mechanisms can lead to periprocedural MI, such as side branch occlusion or vessel spasm; however, distal embolization of atheroma or thrombus seems to be a dominant cause. 6 In a cardiac MRI (cMRI) study of patients undergoing complex native coronary PCI, elevated troponin levels post-PCI correlated with new myocardial enhancement because of side branch occlusion in 43% of cases and in the apical myocardium distal to the stent in 57% of cases, as would be expected with distal embolization. 7Numerous studies have documented the occurrence of distal embolization during both elective and urgent PCI and have characterized its histopathologic substrate. In an analysis of catheter-retrieved materials from human studies of patients undergoing PCI for acute coronary syndrome (ACS), 8 those with no-reflow had significantly higher amounts of visible atheroma and microscopic components such as platelet-fibrin complexes, cholesterol crystals, and macrophages. 8 In another study of 37 lesions in 35 patients undergoing elective PCI, microscopic particles were captured by embolic protection devices (EPDs) in 28 (75.6%) lesions.9 Thrombotic components (fibrin strand-entrapped platelets, leukocytes, and red cells) accounted for the majority (≈75%) of captured debris, whereas plaque components (fibrous tissue, calcium spots, acellular amorphous material, macrophages, foam cells, and cholesterol clefts) accounted for the minority (≈25%).9 Similar findings were demonstrated among 33 patients undergoing either native or saphenous vein graft PCI.10 Supporting these in vivo findings, in a postmortem analysis of patients who died of ischemic heart disease, many had evidence of coronary microemboli, composed of cholesterol crystals, hyaline, and platelet aggregates. 11Clinically, distal embolization can result in asymptomatic biomarker elevation or symptomatic ischemia; angiographically, it can present as visually undetectable silent embolization, macroembolization resulting in epicardial coronary obstruction, or severe microvascular obstruction resulting in no-reflow.Coronary angiography has limited capacity to assess the risk for distal macro-or microembolization. The development of advanced intracoronary imaging techniques and noninvasive imaging techniques, such as coronary computed tomography angiography (CCTA) and cMRI, provides an opportunity for detailed analysis of plaque composition, which can pot...
