Relationship between occlusal force and falls among community-dwelling elderly in Japan: a cross-sectional correlative study.

BACKGROUND: Falls may cause serious health conditions among older population. Fall-related physical factors are thought to be associated with occlusal conditions. However, few studies examined the relationship between occlusal force and falls. To identify the association between occlusal force and falls among community-dwelling elderly individuals in Japan, public health nurses conducted a cross-sectional descriptive study. METHODS: We performed extensive physical assessments of five items: maximum occlusal force, handgrip strength, maximal knee extensor strength, one-leg standing time with eyes open and body sway. We also conducted a questionnaire survey concerning the participants' demographic characteristics, health status and fall experience during the past year. Mean scores and standard deviations were calculated for age and the total points of the index of activities of daily living. Associations were examined using Mann-Whitney tests and logistic regression. RESULTS: We examined 159 community-dwelling people aged ≥65 years, who were independent and active, including 38 participants (24.5%) with experience of falls in the past year. Maximum occlusal force had significant correlation with handgrip strength, maximal knee extensor strength, and one-leg standing time and body sway (P < .05, respectively). We found weak associations between participants with and without a history of falls in terms of the five physical measurements. Logistic regression analysis showed that fall experience was significantly associated with maximum occlusal force (P = 0.004). CONCLUSIONS: This is the first study, led by public health nursing researchers, to examine the associations between maximum occlusal force and falls among community-dwelling elderly in Japan. The results showed that maximum occlusal force was significantly related to the other four extensive physical assessments, and might also suggest that maximum occlusal force assessment by public health nurses could contribute to more sophisticated and precise prediction of fall risks among the community-dwelling elderly. The latest occlusal force measurement device is non-invasive and easy to use. Public health nurses can introduce it at periodical community health checkup assembly events, which might contribute to raising awareness among community-dwelling elderly individuals and public health nurses about fall prevention and prediction.

Falls After Ophthalmological Surgery Experience Among the Community-Dwelling Elderly in Japan.

Community-dwelling elderly are likely to fall even after ophthalmological surgery. To identify the association between falls and ophthalmological surgery and screening experiences among the community-dwelling elderly in Japan, a cross-sectional descriptive study examined 159 community-dwelling people aged ≥ 65 years about an extensive physical assessment, health status, experience of falls, and ophthalmic situations. In this city, the study identified an association between falls and both ophthalmological surgery experience and voluntary attendance at ophthalmic screening among the community-dwelling elderly. Japanese public health nurses should be a bridge between community-dwelling elderly and ophthalmologists in the community to promote attendance at ophthalmic screening.

Effectiveness of community-based health services by nurse practitioners: protocol for a systematic review and meta-analysis.

INTRODUCTION: To realise universal health coverage in an ageing society, adequate provision of appropriately trained human resources is essential. The nurse practitioner (NP) is an autonomous and independent, advanced practice nurse capable of providing treatment and care that can be substituted for some aspects of a medical doctor's (MD's) role, especially in a community setting. Previous systematic reviews found higher levels of patient satisfaction with services provided by NPs than those provided by MDs. As non-communicable diseases become a major health burden requiring long-term healthcare in community settings, this systematic review aims to assess the equivalence of NP services to standard care provided by MDs, and to determine whether their practice is an effective alternative to that of MDs in community settings. METHODS AND ANALYSIS: Relevant randomised controlled trials (RCTs) and cluster RCTs will be searched in the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL and the British Nursing Index. We will assess patient and health system utilisation outcomes of interventions comparing treatment and care provided by NPs in community settings with that provided by MDs. Two authors will independently screen studies for inclusion, consulting with a third author where necessary to resolve discrepancies. The risk of bias of included studies will be assessed using the Cochrane Collaboration risk of bias tool, and quality of evidence using the GRADE approach. Meta-analysis of included studies will be conducted using fixed-effect or random-effects models depending on the degree of between-study heterogeneity. Results will be presented using risk ratios with 95% CI for dichotomous outcomes and standardised mean differences with 95% CI for continuous outcomes. ETHICS AND DISSEMINATION: This systematic review and meta-analysis protocol does not require ethical approval. We will disseminate the findings of this systematic review and meta-analysis via publications in peer-reviewed journals. TRIAL REGISTRATION NUMBER: PROSPEROCRD42014009627.
