Choice of living arrangements.

BACKGROUND: The rights to choose where and with whom to live are widely endorsed but commonly denied to adults with intellectual disabilities (ID). The current study provides a contemporary benchmark on the degree of choice exercised by adult service users in the USA. METHOD: Data came from the National Core Indicators programme. Participants were 6778 adult service users living in non-family-home service settings in 26 US states. RESULTS: Most adults with ID did not participate in choosing where and with whom to live. Those with more support needs because of more severe ID and/or co-occurring conditions experienced less choice regarding living arrangements. Individuals living in their own home or an agency-operated apartment were more likely to choose where and with whom to live than individuals in nursing homes, institutions or group homes. However, few individuals with severe or profound ID chose where and with whom to live regardless of where they lived. CONCLUSIONS: In 2008, despite community-living policies that emphasise choice, many adult service users with ID in the USA experienced little or no choice about where and with whom to live, especially those individuals with more severe ID. Our findings provide a clear endorsement of policies promoting more individualised living settings, such as one's own home or an agency apartment, because these settings do provide substantially more choice about living arrangements.

New bench test for venous cannula performance assessment.

Cannula design is of prime importance for venous drainage during cardiopulmonary bypass (CPB). To evaluate cannulas intended for CPB, an in vitro circuit was set up with silicone tubing between the test cannula encased in a movable preload reservoir and another static reservoir. The pressure-drop (DeltaP) value (P-drainage - P-preload) was measured using Millar pressure transducers. Flow rate (Q) was measured using an ultrasound flowmeter. Data display and data recording were controlled using a LabView application, custom made particularly for our experiments. Our results demonstrated that DeltaP, Q, and cannula resistance (DeltaP/Q) values were significantly decreased when the cannula diameter was increased for Smart and Medtronic cannulas. Smartcanula showed 36% and 43% less resistance compared to Medtronic venous and Medtronic femoral cannulas, respectively. The cannula shape (straight- or curved-tips) did not affect the DLP cannula resistance. Out of five cannulas tested, the Smartcanula outperforms the other commercially available cannulas. The mean (DeltaP/Q) values were 3.3 +/- 0.08, 4.07 +/- 0.08, 5.58 +/- 0.10, 5.74 +/- 0.15, and 6.45 +/- 0.15 for Smart, Medtronic, Edwards, Sarns, and Gambro cannulas, respectively (two-way ANOVA, p < 0.0001). In conclusion, the present assay allows discrimination between different forms of cannula with high or low lumen resistance.
