American Insurance Coverage of Endovenous Ablation for Greater and Lesser Saphenous Varicose Veins.

GOALS/PURPOSE: Severe cases of varicose veins can cause psychological distress as well as physical symptoms including skin discoloration, wounds and burning sensations. One intervention, endovenous laser/radiofrequency ablation, is variably covered by insurance. Insurance coverage for this procedure was assessed for all indications of endovenous laser/radiofrequency ablation as medically necessity criteria. METHODS: A cross-sectional analysis was conducted of 57 insurance policies for endovenous laser/radiofrequency ablation. The insurance companies were selected based on the greatest state enrollment and market share. A web-based search and telephone interviews were utilized to identify the policies. Medically necessary criteria were then extracted from the publicly available policies. RESULTS: Fifty-seven (57) insurance policies were assessed, with 36 (63.2%) of these policies providing coverage for endovenous radiofrequency or laser ablation. Six indications existed for coverage, with the most common indication being the demonstration of valvular reflux (n=29, 80.6%). Of the 29 companies that indicated coverage for valvular reflux, 19 (52.8%) specifically required saphenous reflux. Significantly more companies required saphenous reflux vs other specified types of valvular reflux (52.8% vs 8.3%, p<0.001 for saphenous vs junctional reflux and 52.8% vs 16.7%, p <0.003 for saphenous vs nonspecific). Prior to proceeding with endovenous laser or radiofrequency ablation, up to 33% of insurance companies required a trial of conservative management as medically necessary. CONCLUSION: There is a great discrepancy in insurance policy criteria for coverage of endovenous laser/radiofrequency ablation for the treatment of varicose veins, particularly regarding the requirements for valvular reflux and a trial of conservative therapy.

A brief review of complex regional pain syndrome and current management.

Complex regional pain syndrome (CRPS) is a debilitating chronic pain condition that, although exceedingly rare, carries a significant burden for the affected patient population. The complex and ambiguous pathophysiology of this condition further complicates clinical management and therapeutic interventions. Furthermore, being a diagnosis of exclusion requires a diligent workup to ensure an accurate diagnosis and subsequent targeted management. The development of the Budapest diagnostic criteria helped to consolidate existing definitions of CRPS but extensive work remains in identifying the underlying pathways. Currently, two distinct types are identified by the presence (CRPS type 1) or absence (CRPS type 2) of neuronal injury. Current management directed at this disease is broad and growing, ranging from non-invasive modalities such as physical and psychological therapy to more invasive techniques such as dorsal root ganglion stimulation and potentially amputation. Ideal therapeutic interventions are multimodal in nature to address the likely multifactorial pathological development of CRPS. Regardless, a significant need remains for continued studies to elucidate the pathways involved in developing CRPS as well as more robust clinical trials for various treatment modalities.

Complex regional pain syndrome (CRPS) is a debilitating and complex condition that places a significant physical, psychological and emotional burden upon afflicted patients necessitating multi-modal approaches to treatment.The development of the Budapest criteria provided a robust and well-tested set of diagnostic criteria to aid clinicians in the diagnosis of CRPS.The pathophysiology of CRPS has been challenging to elucidate with numerous proposed mechanisms, altogether suggesting a multi-factorial process is involved in the development of this condition.Non-invasive treatments for CRPS are essential in addressing the physical limitations this disease can cause as well as addressing the significant psychological burden that involves increased incidence of depression and suicidal ideation.Invasive treatments offer promising results, especially when considering dorsal root ganglion stimulation; however, the need for more robust clinical trials remains, especially when considering a small portion of patients who have refractory CRPS resort to amputation to control their pain symptoms.

Ushering in the era of regenerative surgery.

Tissue loss, irrespective of etiology, often requires extensive reconstruction. In many instances, the need exceeds what current treatments and technologies modern medicine can offer. Tissue engineering has made immense strides within the past few decades due to advances in biologics, biomaterials, and manufacturing. The convergence of these three domains has created limitless potential for future surgical care. Unfortunately, there still exists a disconnect on how to best implant these 'replacement parts' and care for the patient. It is therefore vital to develop paradigms for the integration of advanced surgical and tissue engineering technologies. This paper explores the convergence between tissue engineering and reconstructive surgery. We will describe the clinical problem of tissue loss, discuss currently available solutions, address limitations, and propose processes for integrating surgery and tissue engineering, thereby ushering in the era of regenerative surgery.

Use of Clinical Practice Guideline to Improve Management of Osteoarticular Infections in Children.

OBJECTIVES: Osteoarticular infections (OAIs) in children pose significant risks if incorrectly managed. We introduced a clinical practice guideline (CPG) to decrease use of broad-spectrum and intravenous (IV) antibiotics for OAI treatment. The primary aims of our project were to decrease the percent of patients with empirical broad cephalosporin use to 10% and decrease IV antibiotic therapy on discharge to 20% while increasing narrow-spectrum oral antibiotic use to 80% within 24 months. METHODS: We used quality improvement methodology to study patients diagnosed with OAIs. Interventions included multidisciplinary workgroup planning, CPG implementation, education, information technology, and stakeholder feedback. Outcome measures were the percentage of patients prescribed empirical broad-spectrum cephalosporins, percent discharged on IV antibiotics, and percent discharged on narrow-spectrum oral antibiotics. Process measures included percent of patients hospitalized on medicine service and infectious diseases consultation. Balancing measures included rates of adverse drug reactions, disease complications, length of stay, and readmission within 90 days. The impact of the interventions was assessed with run and control charts. RESULTS: A total of 330 patients were included over 96 months. The percentage of patients with empirical broad cephalosporin coverage decreased from 47% to 10%, percent discharged on IV antibiotics decreased from 75% to 11%, and percent discharged on narrow-spectrum oral antibiotics increased from 24% to 84%. Adverse drug reactions decreased from 31% to 10%. Rates of complications, readmissions, and length of stay were unchanged. CONCLUSIONS: Through development and implementation of a CPG for OAI management, we demonstrated decreased use of empirical broad-spectrum antibiotics and improved definitive antibiotic management.

Cefepime-induced Neurotoxicity: Five Cases Reported in a Single Institution.

Cefepime is a fourth-generation cephalosporin widely used to treat gram-positive and gram-negative infections. Its half-life is approximately two hours in patients with normal renal function and may increase to 13.5 hours in patients with acutely or chronically impaired renal function. Although dosage adjustment is recommended for patients with renal insufficiency to prevent drug accumulation, toxicity has been reported in patients even with normal renal function. One underreported complication of cefepime toxicity is cefepime-induced encephalopathy (CIE). While the pathophysiology is unclear, treatment involves early discontinuation of this antibiotic to decrease morbidity and mortality. We report five cases of cefepime-induced encephalopathy occurring within one year at a single institution.

Incubation of food craving is independent of macronutrient composition.

Cues previously paired with rewarding stimuli induce a time-dependent increase in the motivational craving state (incubation of craving). Whether there is an increase in craving for high-fat (HF) food over time, which may contribute to overeating and obesity, has not been determined. We hypothesized that cues paired with HF pellets would elicit a greater incubation of craving effect than those paired with standard chow (SC) pellets. Rats exposed to cues associated with either HF or SC pellets demonstrated equivalent levels of craving over an abstinence period of 30 days. Diet preference tests between SC pellets and LabDiet revealed that SC pellets were preferred over LabDiet. Rats reared on SC pellets exclusively, did not display incubation of craving for SC pellets, suggesting that prior history with the food plays an important role in cue-induced seeking behavior. Results identified cues previously associated with food undergo a comparable magnitude of incubation of craving. When ingestive behavior was measured after 30 days of abstinence, rats significantly increased their consumption of HF pellets. Our results indicate that food cues gain importance over time, trigger increased approach behaviors, and increased consumption of HF food following abstinence. This may contribute to overeating and the development of obesity.
