A scoping review and research synthesis on financing and regulating oral care in long-term care facilities

This scoping study examined and summarised the published literature available and the gaps in knowledge about regulating and financing oral care in long-term care (LTC) facilities. We limited the electronic search to reports on regulating and financing oral care, including reports, commentaries, reviews and policy statements on financing and regulating oral health-related services. The broad electronic search identified 1168 citations, which produced 42 references, including 26 pieces of grey literature for a total of 68 papers. Specific information was found on public and private funding of care and on difficulties regulating care because of professional segregation, difficulties assessing need for care, uncertainty on appropriateness of treatments and issues around scope of professional practice. A wide range of information along with 19 implications and 18 specific gaps in knowledge emerged relevant to financing and regulating oral healthcare services in LTC facilities. Effort has been given to enhancing oral care for frail elders, but there is little agreement on how the care should be regulated or financed within the LTC sector.

Screening for cognitive impairment in the elderly

Mailed questionnaire. Primary care practices in the Ottawa-Carleton region. Family physicians and general practitioners culled from the Yellow Pages and Canadian Medical Directory; 368 of 568 questionnaires were returned for a response rate of 70%. Six respondents had fewer than 30 patients weekly and two responded too late to be included in the analysis; 360 cases were included in the analysis. Responses to 10 questions on cognitive screening and five on demographics and the nature of respondents' practices. About 80% of respondents reported doing at least one mental status examination during the past year. Only 24% routinely screened patients, although 82% believed screening was needed. Major barrie...

A photovoice study of older adults' conceptualizations of risk

Society expects older adults to identify and manage their personal risks yet little is known about the meaning of risk in their daily lives and how they balance the tensions between taking and avoiding risks. Therefore the purpose of this study was to explore how older adults construe risk. A qualitative exploratory study that incorporated photovoice methodology was used. Seventeen older adults, over a weeklong period, took pictures and kept a log of the places, spaces, events, activities, or situations that best represented risk. Subsequently, they participated in a follow-up individual interview. Older adults viewed risk both positively and negatively, judging the saliency of a risk according to criteria that related both to the risk itself and to personal characteristics. Although risk was avoided in specific situations, risk taking was participants&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; primary approach to risk, which assumed three forms: adaptive, opportunistic, and/or unjustifiable. Contrary to societal views, older adults view risk as constructive and personally relevant, and as something to be taken and need to be supported in risk taking rather than risk avoidance.

Hospice residents' interest in complementary and alternative medicine (CAM) at end of life: a pilot study in hospice residences in British Columbia

A pilot study conducted in British Columbia, Canada explored the extent of hospice residents' interest and openness to CAM use. A convenience sample of 48 hospice residents from 9 hospice sites completed questionnaire-based interviews. The majority of participants were Caucasian women over 60 years old. 81 percent expressed interest in receiving CAM; 79 percent used CAM prior to entering the hospice setting. 50 percent of those interested in using CAM felt their partner/friend/other family member would also be interested in receiving CAM, and half of that 50 percent reported personal interest in sharing the experience. Reasons reported for CAM interest were to enhance well-being, relaxation, and for pain relief. Further research could explore how res...

The authors have compared volunteer corps to all ambulance services in Michigan and have focused on the relationship between organizational characteristics, such as membership and community characteristics as indicated by town size, and the support base for the volunteer corps. They conclude that governmental support for voluntary associations such as ambulance corps improves health care delivery in small communities.

The normative sample, aged 16 to 95 years, consisted of 1,300 cognitively intact individuals who resided in the community. Years of education ranged from 0 to 21. The total number of words in 1 minute for each of the letters F, A, and S was correlated r ϭ .52 with the number of animal names generated in 1 minute. Regression analyses showed that FAS was more sensitive to the effects of education (18.6% of the variance) than age (11.0% of the variance). The opposite relationship occurred for Animal Naming, where age accounted for 23.4% of the variance and education accounted only for 13.6%. Gender accounted for less than 1% of variance for FAS and Animal Naming. The clinical utility of these norms is discussed.

Use of background interference procedure to assess visual retention deficits in multiple-sclerosis, psychiatric, and brain-damaged patients

During the noninterference condition, the psychiatric, multiple-sclerosis, and brain-damaged patients functioned at a comparable level. The introduction of a distracting background reduced the level of functioning for only the brain-damaged group. This effect remained significant for the correct score when age and postmorbid intelligence functioning were controlled. These results were interpreted as reflecting the cortical nature of the deficits in resisting the distracting influence of the background interference procedure. Serial testing was recommended for the evaluation of the multiple-sclerosis group.

The Farnsworth-Munsell 100-Hue color vision score and visual evoked potentials in multiple sclerosis

Neuro-Ophthalmology, 1988

ABSTRACT In a study of two groups of multiple sclerosis (MS) patients (57 in Vancouver and 78 in ... more ABSTRACT In a study of two groups of multiple sclerosis (MS) patients (57 in Vancouver and 78 in Saskatoon) visual evoked potentials (VEP), FM 100-Hue color vision (CV), and automated perimetry were performed. The two groups were similar in age and disease duration but the Saskatoon group were more disabled by their disease. In patients with definite or probable MS with or without a history of optic neuritis (ON) the VEP was more often abnormal than the CV; an abnormality in VEP or CV was found in 95% of Vancouver, and 100% of Saskatoon definite or probable MS patients with a history of ON and in 75% of those with no history of ON. An abnormal red-green color axis was found in only 4% of all definite or probable MS eyes, and an abnormal blue-yellow axis in 6%. Half of the eyes with an abnormal color axis also had an abnormal CV score. In both control eyes and MS eyes the most consistent error scores were located in the &#39;blue&#39; quadrant of the FM 100-Hue color circle. Of all eyes with an abnormal VEP 42% had an abnormal CV score and of those with an abnormal CV score 58% had an abnormal VEP. Abnormal color vision in MS probably reflects a different pathology than the demyelination responsible for the VEP latency abnormality and the presence of a specific red-green deficiency suggests that the maculo-papillary fibers are not selectively vulnerable.

The current orthodoxy is a somewhat illogical hybrid of the original theory of significance tests of Edgeworth, Karl Pearson, and Fisher, and the subsequent decision theory approach of Neyman, Egon Pearson, and Wald. This hegemony is under threat from Bayesian statisticians. A third approach is that of likelihood, stemming from the work of Fisher and Barnard. This approach is illustrated using hypothetical data from the Lancet articles by Bradford Hill, which introduced clinicians to statistical theory.

Effects of Screening Errors and Differential Mortality on the Estimation of the Incidence of Dementia in the Canadian Study of Health and Aging

Initial and follow-up estimates could be biased by false-negative error in the screening tool used for subjects living in the community, and by erroneous classification of subjects who died in the interim. Here, we use a deterministic model to quantify those possible biases. We conclude that, using the estimates of the errors from control samples, the incidence among community subjects would be overestimated by 15%, and the incidence among the institutional subjects would be underestimated by 37%. The overall incidence would be underestimated by 14%. Most of the bias can be attributed to inaccuracies in the classification of deaths.
