A two-stage ED intervention, consisting of screening with the ISAR tool followed by a brief, standardized nursing assessment and referral to primary and home care services, significantly reduced the rate of subsequent functional decline.

Integrated systems appear to be feasible and have the potential to reduce hospital and nursing home utilization without increasing costs.

The dramatic global impact of tuberculosis on mortality has been well documented, but its impact on morbidity has not been well described. The emphasis on treatment of latent tuberculosis (TB) infection highlights the tradeoff between short-term decrements in health status from 'preventive' therapy, and long-term gains related to fewer cases of active TB. However, these changes in health status have not been characterized. As a first step, we examined the feasibility and reliability of administering two health status questionnaires, in a multicultural TB clinic setting. The Medical Outcomes Study SF-36 and the EuroQOL EQ-5D were self-administered during 3 weekly interviews. One hundred and eighty-six potentially eligible patients were identified, of whom 112 could be evaluated; 106 (57%) were confirmed eligible. Sixty-seven (63%) agreed to participate; 24 (36%) were women. Fifty-three participants (79%) were foreign-born, with median residence in Canada of 3.5 years. Fifty (75%) of the participants completed all study measurements: 25 were treated for latent TB, 17 for active TB, and eight had previous active TB. Cronbach's alpha coefficients ranged from 0.73 to 0.94 for the SF-36 domain scores. Intraclass correlation coefficients were 0.66 for the SF-36 physical component summary, 0.79 for the mental component summary, and 0.73 for the EQ-5D. These instruments appeared reliable in a highly selected group of TB patients.

Airways responsiveness to a bronchodilator is frequently measured to assist in determining the cause of respiratory symptoms. Clinically, a greater than 15% improvement in the FEV1 is often used to define the "increased" response indicative of asthma. However, unlike other tests of lung function, reference standards derived from "healthy" members of a general population sample have never been reported. As part of a health survey carried out in Alberta, Canada, 2,609 subjects completed a standardized respiratory symptom questionnaire and had FEV1 measured before and 20 min after inhaling terbutaline sulfate via a 750-ml spacer device. Among asymptomatic never-smoking subjects with a FEV1 greater than 80% of predicted, the upper 95th percentile of bronchodilator response (BDR), when expressed as 100 x (FEV1 postBDR - FEV1 preBDR)/predicted baseline FEV1 averaged 9%. This value remained remarkably stable across gender, age (7 to 75 yr), and height groups, and deviated to 6% only when baseline FEV1 was greater than 120% of predicted. Consistent with other respiratory function variables, in which the upper limit of normal is often defined as the upper 95th percentile, our population-derived reference values provide a conceptual definition of BDR that can easily be applied to define "increased" response in the clinical setting.

Le complexe formé par les maladies chroniques, les épisodes de maladies aiguës, les déficiences physiologiques, les incapacités fonctionnelles et les problèmes cognitifs dominent les personnes âgées fragiles. Elles comptent sur l'aide des programmes sociaux et de Santé qui, au Canada, sont encore fragmentés. Le SIPA (Services intégrés pour les personnes âgées fragiles) est un modèle de services intégrés basé sur des services de proximité, une équipe multidisciplinaire et un gestionnaire de cas qui détiennent la responsabilité clinique de l'ensemble des services sociaux et de Santé requis, la capacité de mobiliser des ressources en fonction des besoins et l'application de protocole de soins. Le projet de démonstration SIPA a utilisé un devis expérimental avec assignation aléatoire de 1230 participants, de deux quartiers de Montréal, dans un groupe expérimental et un groupe témoin. Les coûts des services institutionnels ont été de 4270$; inférieur dans le SIPA comparés au groupe témoin, les coûts des services de proximité ont été supérieurs de 3394$;. La proportion des personnes en attente d'hébergement en hôpitaux de courte durée a été deux fois plus élevée dans le groupe témoin que dans le groupe SIPA. Les coûts des hospitalisations de courte durée des personnes du SIPA avec incapacité dans les activités de la vie quotidienne ont été inférieurs d'au moins 4000$; à ceux des personnes du groupe témoin. En conclusion, l'expérimentation SIPA démontre qu'il est possible de s'engager dans des projets de démonstration ambitieux et rigoureux au Canada. Ces résultats ont été obtenus sans augmentation des coûts globaux des services sociaux et de santé, sans diminution de la Qualité des soins et sans augmentation du fardeau des personnes âgées et de leurs proches.
