The Canadian Neurological Scale (CNS) was designed to monitor mentation and motor functions in stroke patients. We assessed its validity and reliability on a group of 157 patients with a diagnosis of acute cerebrovascular accident. We determined validity by (1) correlating scale items and total score with the standard neurologic examination; (2) exploring the scale's predictive power with different end points at 6 months--the initial CNS was a significant predictor of outcome; (3) showing that the CNS had higher correlation coefficients with the initial neurologic examination than the Glasgow Coma Scale; and (4) assessing the responsiveness of the scale to change in the neurologic status of stroke patients. Interobserver reliability, measured by kappa statistics on each scale item, was good. Accordingly, we established the validity and reliability of the CNS for its use in clinical studies and in the care of stroke patients.

Background: With advances in genetic and genomic medicine, the optimal integration of genetic services into the health care system remains of major concern in many countries. Objectives: To review the current organisation of genetic services, mostly in Europe, North America and Australia, explore emerging service delivery models, and probe challenges inherent in the transition process. Methods: We conducted a literature review of genetics in clinical practice: testing, diagnosis, counselling, and treatment. We examined the basic structures of genetic services, examples of integrated networks, and existing professional resources. We investigated services belonging traditionally in medical genetics as well as those developed for more common diseases. Results: Multidisciplinary specialist clinics and coordinated services appeared to be key to delivering proper care in rare genetic disorders. For oncogenetics, neurogenetics and cardiogenetics, interprofessional collaboration between geneticists and other specialists seemed to be favoured. On the other hand, there was also a tendency toward the integration of genetic services directly into primary care. Among the most pressing challenges was the morphing of paediatric care into adult care. Conclusion: The coordination of activities between professionals in first-, second-, and third-line medical care is a primary objective calling for the reconfiguration of professional roles and responsibilities. This entails the forging of new relationships as well as an enhanced sharing of expertise and genetic information, including information regarding services. Barriers to overcome include the redistribution of roles, sharing of data and databases, and the lack of preparedness of non-genetics professionals and of the health care system in general.

The purpose of this study was to examine the effectiveness of different practice-based approaches to assist patients of primary care physicians to quit smoking and sustain cessation. Forty-four nonsmoking general practitioners volunteered for the study. After a period of training, they randomized 923 smoking clients, unselected for motivation toward quitting, to four different intervention groups: (i) minimal intervention, consisting of one single counselling session and a brief handout on quitting techniques; (ii) repeated counselling including reinforcing sessions at Months 1, 3, 6, and 9; (iii) repeated counselling and use of nicotine gum; and (iv) repeated counselling and spirometry. Biochemically validated smoking status was assessed at six and 12 months after recruitment. The proportion of verified quitters at 12 months was 4.8 percent among subjects randomized to the minimal intervention group, compared to 5.5 percent, 7.5 percent, and 6.5 percent among those randomized to the three repeated-counselling groups. In no treatment group was the outcome significantly different from that for one-time counselling at the (P less than 0.05) level. Lack of power, contamination, and low attendance at reinforcing sessions should be taken into account in interpreting the results.

Overall mean changes in depression and physical symptoms during 1 year were small. The observed variability in the individual response to the caregiving situation suggests that future research should focus on the identification of salient prognostic factors.
