Using concept mapping to design an indicator framework for addiction treatment centres.

OBJECTIVE: The objective of this study is to determine an indicator framework for addiction treatment centres based on the demands of stakeholders and in alignment with the European Foundation for Quality Management (EFQM) Excellence Model. SETTING: The setting is the Jellinek Centre based in Amsterdam, the Netherlands, which serves as a prototype for an addiction treatment centre. METHOD: Concept mapping was used in the construction of the indicator framework. During the 1-day workshop, 16 stakeholders generated, prioritized and sorted 73 items concerning quality and performance. Multidimensional scaling and cluster analysis was applied in constructing a framework consisting of two dimensions and eight clusters. RESULTS: The horizontal axis of the indicator framework is named 'Organization' and has two poles, namely, 'Processes' and 'Results'. The vertical axis is named ' Task' and the poles are named 'Efficient treatment' and 'Prevention programs'. The eight clusters in the two-dimensional framework are arranged in the following, prioritized sequence: 'Efficient treatment network', 'Effective service', ' Target group', 'Quality of life', 'Efficient service', 'Knowledge transfer', 'Reducing addiction related problems', and 'Prevention programs'. The most important items in the framework are: 'patients are satisfied with their treatment', 'early interventions', and 'efficient treatment chain'. CONCLUSION: The indicator framework aligns with three clusters of the results criteria of the EFQM Excellence Model. It is based on the stakeholders' perspectives and is believed to be specific for addiction treatment centres. The study demonstrates that concept mapping is a suitable strategy for generating indicator frameworks.

Comparison of fluorotyrosines and methionine uptake in F98 rat gliomas.

The transport mechanisms of O-(2-[(18)F]fluoroethyl)-L-tyrosine (FET) and 2-[(18)F]fluoro-L-tyrosine (FTyr) were compared to those of [(3)H]-Methyl-L-methionine (MET) in F98 rat glioma cells in vitro and by tumor imaging by ex vivo dual tracer autoradiography in F98 rat gliomas. Both, FET and FTyr exhibited similar transport characteristics in F98 glioma cells compared to MET, i.e. mainly a sodium dependent transport similar to system B(0,+) and sodium independent transport via system L. Radioactivity of FET in the acid precipitable fraction was <1% after 120 min incubation time while FTyr and MET exhibited a 15-18% incorporation into proteins. Comparison of FET and FTyr with MET uptake in F98 rat gliomas demonstrated a significant correlation of tumor to brain ratios and a similar intratumoral tracer distribution pattern.

The nonprofit sector's $100 billion opportunity.

Imagine what an extra $100 billion a year could do for philanthropic and other nonprofit institutions. According to a new study, the nonprofit sector could free that amount--maybe even more--by making five changes in the way it operates. The study asked two central questions: Does the sector's money flow from its source to its ultimate use as efficiently and effectively as possible? If not, where are the big opportunities to increase social benefit? According to former senator Bill Bradley and McKinsey's Paul Jansen and Les Silverman, nonprofits could save roughly $25 billion a year by changing the way they raise funds. By distributing funds more quickly, they could put an extra $30 billion to work. Organizations could generate more than $60 billion a year by streamlining and restructuring the way in which they provide services and by reducing administrative costs. And they could free up even more money--an amount impossible to estimate--by better allocating funds among service providers. The authors admit that making those changes won't be easy. The nonprofit world, historically seen as a collection of locally focused charities, has become an enormous sector, but it lacks the managerial processes and incentives that help keep the for-profit world on track. And when the baby boomers start to retire in less than a decade, public budgets will be squeezed even more than they are today. If the nonprofit sector is to help the nation cope with the stresses ahead, it must become more efficient and challenge its traditional concepts of stewardship.

Propylene glycol accumulation associated with continuous infusion of lorazepam in pediatric intensive care patients.

OBJECTIVE: To determine if propylene glycol accumulates in children receiving continuous lorazepam infusion and, if accumulation occurs, to determine if it is associated with significant laboratory abnormalities. DESIGN: Prospective study. SETTING: A tertiary care pediatric intensive care unit. PATIENTS: Eleven intubated pediatric intensive care patients receiving continuous lorazepam infusion for sedation. INTERVENTIONS: Propylene glycol accumulation was determined by comparing concentrations at baseline, after 48 hrs, and at end of therapy. Laboratory abnormalities were determined by comparing serum lactate and osmolar gap at baseline, after 48 hrs, and at end of therapy. Correlation between the cumulative dose of lorazepam received and the propylene glycol concentration measured at the end of therapy was determined. MEASUREMENTS AND MAIN RESULTS: Patients aged 1-15 months were studied. Lorazepam infusion rates ranged from 0.1 to 0.33 mg.kg.hr and lasted 3-14 days. Propylene glycol accumulated significantly in patients receiving continuous infusion of lorazepam. The propylene glycol concentration increased during the study from 86 +/- 93 microg/mL at baseline to 763 +/- 660 microg/mL at the end of the study ( p=.038). A statistically significant correlation between the cumulative dose of lorazepam received and propylene glycol concentration at the end of therapy was demonstrated ( r(2)=.65, p<.005). However, the propylene glycol accumulation was not associated with significant laboratory abnormalities. Neither serum lactate concentrations nor osmolar gap were significantly elevated over baseline. CONCLUSION: Propylene glycol accumulated significantly in pediatric intensive care patients receiving continuous lorazepam infusion, and propylene glycol concentration correlated with the cumulative lorazepam dose the patient received. However, significant laboratory abnormalities due to propylene glycol accumulation were not observed.
