Frequent use of emergency department (ED) services is often perceived to be a potentially preventable misuse of resources. The underlying assumption is that similar and more appropriate care can be delivered outside of EDs at a lower cost. To reduce costs and incentivize more appropriate use of services, there have been efforts to design interventions to transition health care utilization of frequent users from EDs to other settings such as outpatient clinics. Many of these efforts have succeeded in smaller trials, but wider use remains elusive for varying reasons. There are also some fundamental problems with the assumption that all or even the majority of frequent ED use is misuse and invoking reasons for that excessive use. These tenuous assumptions become evident when frequent users as a group are compared to less frequent users. Specifically, frequent users tend to have high levels of frequent ED use, have a higher severity of illness, be older, have fewer personal resources, be chronically ill, present for pain-related complaints, and have government insurance (Medicare or Medicaid). Because of the unique characteristics of the population of frequent users, we propose a research agenda that aims to increase the understanding of frequent ED use, by: 1) creating an accepted categorization system for frequent users, 2) predicting which patients are at risk for becoming or remaining frequent users, 3) implementing both ED-and non-ED-based interventions, and 4) conducting qualitative studies of frequent ED users to explore reasons and identify factors that are subject to intervention and explore specific differences among populations by condition, such as mental illness and heart failure.

In mild gallstone pancreatitis, laparoscopic cholecystectomy performed within 48 hours of admission, regardless of the resolution of abdominal pain or laboratory abnormalities, results in a shorter hospital length of stay with no apparent impact on the technical difficulty of the procedure or perioperative complication rate.

Background. The current mainstay of lymphedema therapy has been conservative nonsurgical treatment. However, surgical options for lymphedema have been reported for over a century. Early surgical procedures were often invasive and disfiguring, and they often had only limited long-term success. In contrast, contemporary surgical techniques are much less invasive and have been shown to be effective in reducing excess limb volume, the risk of cellulitis, and the need for compression garment use and lymphedema therapy. Microsurgical procedures such as lymphaticovenous anastomosis and vascularized lymph node transfer lymphaticolymphatic bypass can treat the excess fluid component of lymphedema swelling that presents as pitting edema. Suction-assisted protein lipectomy is a minimally invasive procedure that addresses the solid component of lymphedema swelling that typically occurs later in the disease process and presents as chronic nonpitting lymphedema. These surgical techniques are becoming increasingly popular and their success continues to be documented in the medical literature. We review the efficacy and limitations of these contemporary surgical procedures for lymphedema. Methods. A Medline literature review was performed of lymphedema surgery, vascularized lymph node transfer, lymphaticovenous anastomosis, lymphatic liposuction, and lymphaticolymphatic bypass with particular emphasis on developments within the past 10 years. A literature review of technique, indications, and outcomes of the surgical treatments for lymphedema was undertaken.Results. Surgical treatments have evolved to become less invasive and more effective. Conclusions. With proper diagnosis and the appropriate selection of procedure, surgical techniques can be used to treat lymphedema safely and effectively in many patients when combined with integrated lymphedema therapy.Lymphedema is a progressive and debilitating condition associated with dysfunction of the lymphatic system. While a small percentage of cases are congenital, most patients in developed countries present with lymphedema resulting from treatment of malignancy. The true incidence of lymphedema is difficult to determine as a result of significant differences in diagnostic criteria. However, lymphedema is reported to occur in up to 49 % of breast, 20 % of gynecologic, 16 % of melanoma, 10 % of genitourinary, and 6 % head and neck cancer patients after lymph node dissection and/or radiotherapy. Even among patients who undergo isolated axillary sentinel lymph node biopsy, up to 7 % have measurable arm differences, and up to 10 % have subjective symptoms of lymphedema.

Background. Effective surgical treatments for lymphedema now can address the fluid and solid phases of the disease process. Microsurgical procedures, including lymphaticovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT), target the fluid component that predominates at earlier stages of the disease. Suctionassisted protein lipectomy (SAPL) addresses the solid component that typically presents later as chronic, nonpitting lymphedema of an extremity. We assess the outcomes of patients who underwent selective application of these three surgical procedures as part of an effective system to treat lymphedema. Methods. This is a retrospective chart review of patients with lymphedema who underwent complete decongestive therapy followed by surgical treatment with SAPL, LVA, or VLNT. The primary outcomes measured were postoperative volume reduction (SAPL), daily requirement for compression garments and lymphedema therapy (VLNT and LVA), and the incidence of severe cellulitis. Results. Twenty-six patients were included in the study, of which 10 underwent SAPL and 16 underwent LVA or VLNT. The average reduction of excess volume by SAPL was 3,212 mL in legs and 943 mL in arms, or a volume reduction of 87 and 111 %, respectively, when compared with the unaffected, opposite sides. Microsurgical procedures (VLNT and LVA) significantly reduced the need for both compression garment use (p = 0.003) and lymphedema therapy (p \ 0.0001). The overall rate of cellulitis decreased from 58 % before surgery to 15 % after surgery (p \ 0.0001).Conclusions. When applied appropriately to properly selected patients, surgical procedures used in the treatment of lymphedema are effective and safe.Lymphedema in the developed world commonly occurs after lymph node dissection and/or radiotherapy to nodal basins for breast cancer, melanoma, or gynecologic malignancies. Less commonly, lymphedema occurs as a result of congenital causes.

This report reflects the proceedings of a breakout session, "Surge Capacity: Defining Concepts," at the 2006 Academic Emergency Medicine Consensus Conference, "Science of Surge Capacity." Although there are several general descriptions of surge capacity in the literature, there is no universally accepted standard definition specifying the various components. Thus, the objectives of this breakout session were to better delineate the components of surge capacity and to outline the key considerations when planning for surge capacity. Participants were from diverse backgrounds and included academic and community emergency physicians, economists, hospital administrators, and experts in mathematical modeling. Three essential components of surge capacity were identified: staff, stuff, and structure. The focus on enhancing surge capacity during a catastrophic event will be to increase patient-care capacity, rather than on increasing things, such as beds and medical supplies. Although there are similarities between daily surge and disaster surge, during a disaster, the goal shifts from the day-to-day operational focus on optimizing outcomes for the individual patient to optimizing those for a population. Other key considerations in defining surge capacity include psychosocial behavioral issues, convergent volunteerism, the need for special expertise and supplies, development of a standard of care appropriate for a specific situation, and standardization of a universal metric for surge capacity.
