Análisis y minimización del riesgo de rotura de stock aplicado a la gestión en farmacia hospitalaria

ObjectiveTo determine how many dispensary drugs should be in the safety stock in a tertiary hospital in accordance with the risk level and the number of days that the hospital is able to withstand a stockout.MethodsWe statistically analysed the infliximab order recorded over a period of 120 days. This drug is relevant for this study as it is costly and is immediately supplied to the clinic. Using the data records for purchasing and dispensing in our department, we created a table to compare the level of risk assumed with the number of units in stock and the number of days that the safety stock should last. In addition, we calculated how much stock there should be in accordance with different heuristic rules used by pharmacy departments.ResultsIn the period being studied, the daily order was 11.4 ± 14.8 units of infliximab. Using the methodology proposed, we discovered that there should be 79 units in the safety stock. Other hospital rules determine values of 47 and 119 units.ConclusionsThe method proposed allows us to discover the risk level that is assumed when selecting the safety stock. Therefore, we are able to design a safety stock policy consistent with the risk level adopted. Under certain assumptions the safety stock quota provided by this method could be reduced. Lastly, there is a notable difference between the safety stock values suggested by different rules, as it has been shown in this article. 相似文献

In this review, we report the state-of-the-art of polymers in thermoelectricity. Classically, a number of inorganic compounds have been considered as the best thermoelectric materials. Since the prediction of the improvement of the figure of merit by means of electronic confinement in 1993, it has been improved by a factor of 3–4. In the mean time, organic materials, in particular intrinsically conducting polymers, had been considered as competitors of classical thermoelectrics, since their figure of merit has been improved several orders of magnitude in the last few years. We review here the evolution of the figure of merit or the power factor during the last years, and the best candidates to compete with inorganic materials. We also outline the best polymers to substitute classical thermoelectric materials and the advantages they present in comparison with inorganic systems. 相似文献

BackgroundNursing clinics in rheumatology (NCR) are organizational models in the field of nursing care. There are various NCR models, but there is no consensus on its operational definition. Our objective is to develop quality standards to define and characterize a NCR.MethodTwo-round Delphi method. The panel consisted of 67 experts: Rheumatologists and nurses of the nursing working group of the Spanish Society of Rheumatology (SSR). The Delphi questionnaire was developed after a literature and experience review from previous SSR projects. The questionnaire consists of 7 sections: general considerations, standards of structure, process, treatment and monitoring, health education, training and research and quality of care. Each item was scored from 1 (least important) to 9 (most important) or by assigning a number (e.g., waiting days). The degree of agreement among the experts was categorized according to the coefficient of variation (CoV) between very high (CoV≤25%) and very low (CoV>100%).ResultsThe second round questionnaire (182 items) was answered by 46 panelists (34 rheumatologists and 12 nurses). A very important agreement was reached on the general standards of structure, process, treatment and monitoring, health education and quality of care. Less agreement was observed on standards related to training time, number of recommended nurses’ research projects and publications.ConclusionThe standards developed in this study would be useful for establishing desirable quality standards of structure and process, and criteria for clinical work, research and teaching that can be used to develop and evaluate the NCRs. 相似文献

Progressive supranuclear palsy (PSP) is a disorder of unknown pathogenesis. Familial clusters of PSP have been reported related to mutations of protein tau. We report the linkage of a large Spanish family with typical autosomal dominant PSP to a new locus in chromosome 1. Four members of this family had typical PSP, confirmed by neuropathology in one case. At least five ancestors had similar disease. Other members of the family have incomplete phenotypes. The power of the linkage analysis was increased by detecting presymptomatic individuals with 18F-fluoro-dopa and 18F-deoxyglucose positron emission tomography. We screened the human genome with 340 polymorphic markers and we enriched the areas of interest with additional markers. The disease status was defined according to the clinical and positron emission tomography data. We excluded linkage to the tau gene in chromosome 17. PSP was linked, in this family, to one area of 3.4 cM in chromosome 1q31.1, with a maximal multipoint < OD score of +3.53. This area contains at least three genes, whose relevance in PSP is unknown. We expect to further define the gene responsible for PSP, which could help to understand the pathogenesis of this disease and to design effective treatment. 相似文献

Hepatic artery anastomotic stenosis after transplantation: treatment with percutaneous transluminal angioplasty 总被引:2,自引:0,他引:2
J Abad E G Hidalgo J M Cantarero G Parga R Fernandez M Gomez F Colina E Moreno 《Radiology》1989,171(3):661-662
Two orthotopic liver transplant recipients underwent percutaneous transluminal angioplasty (PTA) for stricture of the hepatic arterial anastomosis. In both, arterial revascularization was effected by end-to-end anastomosis between the donor common hepatic artery and the recipient's hepatic artery. Both patients had elevated liver enzyme levels, abnormal results on duplex Doppler images, and severe stricture on angiograms. In one patient, percutaneous biopsy revealed graft ischemia. PTA was performed successfully without complications. PTA produced substantial improvement in biochemical, duplex Doppler, histologic, and angiographic patterns. Both patients were asymptomatic 5 and 6 months after PTA. 相似文献

High-dose intra-arterial urokinase for the treatment of hepatic artery thrombosis in liver transplantation 总被引:9,自引:0,他引:9

Two recipients of orthotopic liver transplants (OLT) underwent intra-arterial thrombolytic treatment for hepatic artery thrombosis. Complete clot lysis was achieved in both using infusion of high-dose urokinase directly into the thrombus for 12 and 3 hours, respectively. Percutaneous transluminal angioplasty (PTA) was later carried out successfully on various strictures. Doppler ultrasonography confirmed arterial permeability one month after treatment. Liver transplantation is now an accepted therapeutic option in some patients with irreversible liver failure. Although the results of this procedure have improved radically since cyclosporine was introduced in 1978, life-threatening postoperative complications still occur. The one with the worst prognosis is hepatic artery thrombosis (HAT), with 64% mortality despite retransplantation. HAT was found in 7.4% of liver transplant recipients in a recent review of the most important group of these patients. Fibrinolytic treatment using an exogenous plasminogen activator, urokinase (UK), is effective and safe in the thrombotic obstruction of acute pulmonary embolism, acute myocardial infarction, and graft or peripheral arterial occlusion. We used intra-arterial thrombolysis in two patients with HAT of the liver graft, to avoid retransplantation and to treat a complication secondary to percutaneous transluminal angioplasty (PTA) of an anastomotic stricture, respectively. To our knowledge, this is the first report of treatment of HAT by direct infusion of urokinase in liver transplantation. 相似文献
