48. Non-Certified Surgical Assistants We would like to ask if the payers have policies on supervision of non-certified Surgical Assistants in the outpatient setting? The surgeon would be present in the office suite providing direct supervision. The services would be billed under the surgeon's name. We are not asking about incident to guidelines because the surgeon may not see the patient prior to the SA service. Barbara Roan-Kastanos HealthPartners ; RECOMMENDATION: Non-certified surgical assistants are not recognized and may not bill for assist-atsurgery services neither are their services are billable under the supervising surgeon. Additionally, non-certified surgical assistants cannot practice independently and have services billed under the supervising provider number.
Our experiments using the PKC antagonists calphostin C and BIM were designed to confirm the role of PKC in the suppression of OTR. The doses that we used 5 - 50 nM ; were based on earlier work in cultured rat uterine myocytes that demonstrated significant inhibition of serotonininduced increases in MMP-13 synthesis 30 ; . We were surprised that neither of these PKC antagonists decreased basal or TPA-stimulated nuclear concentrations of AP-1. Subsequent studies in the literature have used many-fold higher concentrations .5 1 M ; these antagonists to inhibit PKC activity in uterine myocytes 12, 17, 29 ; . Unfortunately, our experiments using the PKC antagonists do not help to decipher the role of PKC in the suppression of OTR.
An alternative to warfarin is the extended use of low molecular weight heparin for venous thromboembolism. If there are problems with compliance or with recurrent wild fluctuations in the INR, low molecular weight heparin can be administered under supervision. It is important to measure renal function as accumulation occurs with renal impairment, particularly when the creatinine clearance falls below 30 mL min.

Indications eg, oral celecoxib for "arthritis" prescribed concurrently with injectable ketorolac for "pain control" ; . Errors involving duplicate routes of administration eg, concomitant intravenous heparin and subcutaneous enoxaparin ; may be particularly hazardous. As previously reported, 10 medications available in special dosage formulations are commonly involved in errors caused by disruption of drug delivery characteristics when administered by the wrong route or technique. Medications available in controlledrelease forms such as isosorbide mononitrate, nifedipine, and diltiazem are frequently involved in errors when they are ordered to be administered through a nasogastric tube, which will disrupt the dosage form's controlled-release characteristics. Drug delivery can be markedly altered when dosage.

In reply: Drs Daneschvar and Daw underscore the importance of keeping HIT in the differential diagnosis of thrombocytopenia. Obviously we concur, as exemplified by the "do not miss HIT" warning line in Figure 4 of our article. However, we welcome the additional information in view of the tremendous clinical relevance linked to this subject. In fact, because of the widespread use of heparin in both inpatient and outpatient practice, the incidence of HIT might be higher than that of idiopathic thrombocytopenic purpura ITP ; 1, 2 or other wellknown causes of thrombocytopenia.3, 4 Furthermore, HIT may be an underrecognized contributor to thrombocytopenia associated with sepsis and antibiotic use.5 Heparin is used in routine clinical practice to prevent and treat thromboembolic disease. Its action is indirect; it binds to antithrombin III and enhances its antithrombin activity. Any patient exposed to heparin in any form or dose, including heparin flushes, is at risk of HIT and the associated thrombotic complication. Both unfractionated heparin and low-molecular-weight heparin LMWH ; can cause HIT, although the incidence is lower with LMWH, which is one argument, among others, 6-9 in favor of use of LMWH instead of unfractionated heparin. Although 2 types of pathogenetically and prognostically different HIT nonimmunemediated type I and immune-mediated type II ; are identified, we favor initial consideration of the clinically detrimental type type II ; , regardless of duration of therapy. This is and herceptin.
Major changes are indicated at the CXC interface. This strongly suggests that the CCL2 CCL8 heterodimer has the CC-type conformation. We subsequently investigated the effect of GAG binding on chemokine heterodimerization. For these studies, we chose the heparin pentasaccharide, Arixtra, because it is homogeneous unlike heparin and other natural GAGs heparan sulfate, chondroitin sulfate etc ; that are heterogeneous in both size and composition. Homogeneity of the GAG greatly simplifies interpretation of the mass spectrometry data, allowing us to distinguish heterodimer GAG from homodimer GAG complexes. Arixtra is nearly identical to a fully sulfated heparin pentasaccharide except for one sulfate that is at an unnatural position, and in a separate study, we demonstrated that its interaction with chemokines is similar to heparin in the context of FTICR mass spectrometry assays 20 ; . We chose Arixtra because it is longer than other commercially available homogenous GAG homologues. However, it is important to note that like any model GAG, Arixtra does not capture the potential diversity of protein-GAG interactions or mimic quantitatively the true in vivo interactions. Using the mass spectrometry based filtration trapping assay 9 ; , we observed that Arixtra binds each of the CCR2 ligands. Each possible pair of CCR2 ligands was then mixed with Arixtra, and the resulting solution was analyzed by ESI-FTICR MS. As shown in Figure 6A, a solution of CCL8, CCL11 and Arixtra in 100 mM NH4OAc gave well-resolved mass spectra. Strikingly, although no heterodimerization of these two chemokines was observed in the absence of Arixtra Figure 6B ; , abundant heterodimer in complex with Arixtra CCL8 CCL11 Arixtra ; was observed for the equimolar mixture of these molecules Figure 6A ; . The heterodimer Arixtra complex was more abundant than the homodimer Arixtra complex.

Pharmacy Practice Residency, Virginia Mason Medical Center, Seattle, WA marika.saarinen vmmc ; . Cholesterol-lowering medications have been shown to provide a cardiovascular and total mortality benefit for patients with clinically evident cardiovascular disease secondary prevention ; . However, it is necessary for these high-risk patients to be at goal, which requires checking lipid profiles and properly prescribing and titrating medications. The purpose of this initiative was to improve lipid management outcomes in a designated payer population. The project consisted of two parts: global population-based ; and targeted patient-specific ; interventions. Global interventions via e-mail education, P&T changes, therapeutic interchanges, and pharmacy staff interventions targeted the medical center and prescribers with the intent of increasing generic statin use by educating about newly available generic agents. To measure outcomes of the global interventions, generic utilization rates were analyzed. Targeted interventions focused on specific patients with diabetes, coronary artery disease, or both conditions. LDLs were assessed to determine which patients were not at goal, and those patients were contacted for labs and follow-up appointments with an ultimate goal of statin initiation and or titrating doses for LDL optimization. Results and conclusions will be presented. 306 A3 ; Thursday 11: 00 Acacia EFFECTIVENESS AND SAFETY OF THE CURRENT ASPIRIN REGIMEN IN VA PATIENTS POST-PERCUTANEOUS CORONARY INTERVENTION WITH DRUG ELUTING STENTS, A3 ; . Megan Au, Ramin Ebrahimi, Cynthia Jackevicius. VA Greater Los Angeles Healthcare System, Los Angeles, CA. megan.au va.gov ; Recent reports have indicated that there may be an increased risk of late stent thrombosis with the use of drug eluting stents, as compared to bare metal stents. Off label use of drug eluting stents in complex conditions such as multivessel disease or acute myocardial infarction ; or with complex lesions for example saphenous vein bypass grafts, bifurcating lesions, and chronic total occlusions ; have been implicated as a significant cause of thrombosis. However, there is also much concern that inadequate antiplatelet therapy early discontinuation or insufficient dosage ; post stent placement may contribute substantially to late stent thrombosis. Current product labeling as well as the American College of Cardiology American Heart Association recommend treatment with a thienopyridine clopidogrel or ticlopidine ; for 3 months after sirolimus eluting stent implantation, 6 months after paclitaxel eluting stent implantation, and preferably 12 months for both in patients who are at low risk for bleeding. Life long aspirin is also recommended although the optimal dose has never been thoroughly evaluated. This is a retrospective study conducted to evaluate the effectiveness and safety of the current aspirin regimen for a group of patients who received a drug eluting stent during the period of April 2003 to July 2006. Results will be presented. 307 A3 ; Thursday 11: 30 Acacia OUTCOMES ASSOCIATED WITH CONCOMITANT ANTICOAGULANT ANTIPLATELET AND ANTIPLATELET ANTICOAGULANT THERAPY: A FOLLOW-UP STUDY A3 ; . Kristina Rogers, Samuel Johnson, Tom Thomas Delate, Dan Witt. Kaiser Permanente Colorado, Denver, CO, kristina.r.rogers kp ; While there is strong evidence supporting the efficacy of antiplatelet therapy for primary and secondary prevention of thromboembolic events in patients with coronary artery disease, use of antiplatelet therapy in combination with oral anticoagulants remains controversial and ill-defined. A study previously conducted at Kaiser Permanente Colorado KPCO ; demonstrated a high prevalence of selfreported concomitant use of antiplatelet therapy with warfarin in patients monitored by the KPCO Clinical Pharmacy Anticoagulation Service. This retrospective, longitudinal cohort study will provide follow-up estimates of the annual incidence rates of hemorrhage and thromboembolism in the patients who were reported receiving concomitant therapy with warfarin and aspirin, clopidogrel, and or dipyridamole relative to the patients who reported receiving warfarin monotherapy. Electronic rRecords of approximately 42600 patients identified during the previous study will be examined for a diagnosis of hemorrhage or thromboembolism requiring coded duringassociated with an inpatient hospitalization or emergency department visit or of thromboembolism. Results will be presentedP as proportions of patients wieach cohort with a hemorrhagic event or thromboembolic event. will be compared between patients receiving combination and monotherapy. Associations will also be examined between the cohorts and outcomes while adjusting for the potential confounding byof demographic and comorbidity variables. This research will provide essential data to practitioners, anticoagulation services, and the healthcare community at-large regarding the clinical outcomes of patients receiving concomitant warfarin and antiplatelet therapy.

Swedish Medical Center, Seattle, WA, Jennifer.Riddell Swedish ; . In the "ACC AHA Guidelines for the Management of Patients with ST-Elevation Myocardial Infarction" STEMI ; the goal time for doorto-balloon is within 90 minutes if percutaneous coronary intervention PCI ; is chosen. Within the first 90 minutes, several steps must be completed including obtaining a diagnostic electrocardiograph and laboratory draws, administering medications and transferring the patient to the PCI laboratory. The objective of this study is to reduce the time to medication delivery to patients in the emergency department ED ; with a STEMI through implementation of a STEMI medication box. Decreasing the time for medication administration between the door and the PCI laboratory will decrease overall time to balloon in an effort to reach the 90 minute goal. The STEMI box contains three doses of metoprolol 5mg IV, four tablets of 81mg chewable aspirin, one vial of 0.4mg nitroglycerin SL tablets and one vial of heparin 1, 000 units ml. The STEMI box is maintained in the ED, and may save time by allowing nurses to bring all the medications for a STEMI at once, instead of and hms.

| Sq heparin injection sitesResponsibility for the CEMD was transferred to the National Institute for Clinical Excellence NICE ; in 2000. NICE is reviewing the most appropriate format for this and the other condential enquiries those into stillbirths and deaths in infancy CESDI ; , perioperative deaths, and homicides and suicides ; . NICE has proposed that in 2003 the CEMD will merge with CESDI to form a new Maternal And Child Health Condential Enquiry. This would benet the CEMD, in terms of increased administrative support, as this enquiry has always been undertaken on an extremely modest budget, representing enormous value for money. This is in a large part because of the whole-hearted support of the profession, particularly the regional assessors who give of their free time to evaluate the individual cases. It is vital that the current feeling of ownership of the CEMD is retained. Although still going through the consultation exercise, it is possible that the future format could include comparisons of deaths with near misses. For this to be successful, much better information systems than are currently available will be needed. It is further hoped to include pregnancy-based elds in the Intensive Care National Audit Research Centre ICNARC ; data set. If this is achieved, it would help identify some of the near misses.

Heparin hydrochloride
Heparin is administered to prevent coagulation of blood not only during initial stabilization and external cooling, but during subsequent air shipment of the patient as well. This is important, because blood will normally clot if it is not kept in constant motion, even within the blood vessels of the body. Obviously, after external cooling is complete, artificial circulation will be discontinued to facilitate air transport and clotting, in the absence of anticoagulation, would normally be expected to occur. It should be noted that the effectiveness of heparin is to a great extent dependent upon proper control of pH. If the pH drops significantly below 7.0 more than 0.3 units ; heparin will start to degrade and inactivate. Adequate control of pH is thus essential in order to achieve and maintain anticoagulation. Note: Heparin will not reverse clotting -- it only prevents it. 5 ; Pack 3 Streptokinase Streptase ; dosage 1 * 250000U5 ml vial given IV ; Streptokinase is a fibrinolytic clot dissolving ; agent to be used only in patients who have experienced 1 or more hours of ischemia in the absence of cardiopulmonary support or transport medications.

In the event ofsevere and unremitting rejection, when rescue therapy with pulse steroids and monoclonal antibodies fail to reverse the rejection episode, it may be preferable to switch to alternative immunosuppressive therapy rather than increase the Neorala dose to excessive levels. Occasionally patients have developed a syndrome of thrombocytopenia and microangiopathic hemolytic anemia which may result in graft failure. The vasculopathy can occur in the absence ofrejection and is accompanied by avid platelet consumption within the graft as demonstrated by Indium 111 labeled platelet studies. Neither the pathogenesis nor the management of this syndrome is clear. Though resolution has occurred after reduction or discontinuation ofcyclosporine and 1 ; administration of streptokinase and heparin or 2 ; plasmapheresis, this appears to depend upon early detection with Indium 111 labeled platelet scans. See ADVERSE REACTIONS ; Sinificant hyperkalemia sometimes associated with hyperchloremic metabolic acidosis ; and hyperuncemia have been seen occasionally in individual patients. Hepatotoxicity associated with cyclosponne use had been noted in 4% ofcases of renal transplantation, 7% ofcases ofcardiac transplantation, and 4% ofcases of liver transplantation. This was usually noted during the first month of therapy when higft doses of cyclosporine were used and consisted of elevations ofhepatic enzymes and bilirubin. The Chemistry elevations usually decreased with a reduction in dosage. As in patients receiving other immunosuppressanls, those patients receiving cyclosporine are at increased risk for development oflymphomas and other malignancies, particularly those ofthe skin. The increased risk appears related to the intensity and duration olimmunosuppression rather than to the use of specific agents. Because of the danger ofoversupression ofthe immune system resulting in increased risk of infection or malignancy, a treatment regimen containing multiple ammunosuppressants should be used with caution. There have been reports ofconvulsions in adultand pediatric patients receiving cydosporine, particularly in combination with high dose methylprednisolone. care should be taken in using cyclosporine with nephrotoxic drugs. See PRECAUTIONS ; Because Neoral5 is not bioequivalent to SandimmUne# , conversion from Neorala to Sandimmune 1: ratio mg kg day ; may result in lower cyclosporine blood concentrations. conversion from Sandimmune should be made with increased monitoring to avoid the potential of underdosing. PRECAUTIONS: General: side effect ofcyclosporine using a Neoral# o t and heparin.

Of either AT Ill or heparin in the reaction mixture, factor VIla was migrated as a single band with an apparent molecular weight of 50 Kd figure not shown ; . As expected from the data of Fig I, either no or only minimal amounts of factor VIIa was complexed with AT Ill within this time period if TF was omitted from the reaction mixture Fig 5 ; . The ability o AT III heparin to inhibitlactor VIIa bound f to cell surjhce TF. The evidence that AT III heparin could inactivate factor VIIa bound to reconstituted purified T F in suspension led us to determine whether AT Ill in the presence of heparin could also inactivate factor VIIa bound to T F expressed on cell surfaces. Monolayers of OC-2008 cells were incubated at 37OC with factor Vlla IO nmol L ; in buffer B for 1 hour to allow saturation binding of factor VIla to TF sites on the monolayers. After this, the monolayers were washed three times with icecold buffer B to remove unbound factor VIla. Then, buffer B containing ['HI factor X IO pg the presence or absence of AT Ill 100 pg mL ; , h ann I U mL ; , both was added to the monolayers. The time course of factor X activation was determined by measuring activation peptide release as trichloroaceticacid-soluble counts in serial subsamples. As expected from earlier experiments, " the addition of heparin alone to the reaction mixture yielded an enhanced rate of factor VIIa cell surface TF catalyzed activation of factor X. In contrast to the above experiments with purified reconstituted TF, adding AT Ill alone resulted in a variable, but consistent inhibition of factor VIIa cell surface T F catalyzed activation of factor X. However, in all experiments, maximum inhibition of factor VIIa bound to cell surface T F was observed in reaction mixtures containing AT Ill plus exogenously added heparin Fig 6 ; . Because trace concentrations of TFPI, possibly present either as a contaminant in our purified reagents or secreted endogenously by the carcinoma cells, could have accounted for the above results, additional experiments were performed in which a mixture of AT 111 and heparin was incubated for 30 minutes with anti-TFPI IgG and then added to the mono and hydralazine.
