- Few studies have investigated the measurement error of the Mini-Mental State Examination (MMSE) in the same unit of measurement, also known as absolute reliability. This measurement can help determine whether an observed score change for an individual is likely to represent true change. The aim of this study was to investigate the absolute reliability of the MMSE among individuals with dementia that reside in nursing homes. Among 88 participants, 19 (21.6%) were men, 35 (39.8%) had Alzheimer's disease, 35 (39.8%) had vascular dementia, and the mean age was 84.0 years (range 65-98). The participants were tested and retested with the MMSE within 1-6 days. Both tests were administered by the same assessor at the same time of day. The mean MMSE score was 13.7 (range 0-28). The absolute difference between MMSE scores varied from 0 to 6 points, and the differences did not correlate with the corresponding score means (p = 0.874). The smallest detectable change (SDC) between two measurements was 4.00. The SDC was independent of depression, impaired vision and hearing, delirium within the last week, dementia type and age. However, the SDC was 5.56 among men and 3.50 among women (p = 0.003). In conclusion, for individuals with dementia that reside in nursing homes, it seems like their MMSE score needs to change by four or more points between two measurements in order for their score change to be reliably higher than the measurement error.

Falls and fall prevention in community-dwelling older adults
- 2018

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Falls are the primary cause of injuries among older adults, and accidents that result from falls can lead to personal suffering and extensive societal burdens. The overall aims of this thesis were to explore and describe falls and fall prevention strategies in community-dwelling older adults and to evaluate a fall prevention home exercise program, the Otago Exercise Program (OEP), with or without motivational interviewing (MI).Methods: Qualitative and quantitative research methods were uses. The designs were as follows: a cross-sectional, descriptive and comparative study (study I); a descriptive feasibility investigation (study II) and a randomized controlled trial (RCT) with two interventions, the OEP and OEP+MI, as well as a control group, with a 12-month follow-up (study III); and a prospective and descriptive study (study IV). The four studies comprised community-dwelling individuals aged 75 years or older. Study I included 262 individuals and studies II-IV had 175 participants who needed walking aids or home support. Study II also included 12 physical therapists. Data collection was performed via self-reported questionnaires, fall calendars, exercise diaries, physical performance tests and a semi-structured questionnaire. Results and conclusions: Suggested actions to prevent falls significantly differed between high and low active older adults (study I). Support for self-directed behavioral strategies could be important for preventing falls in older adults who have low physical activity levels. The study protocol for the RCT had acceptable feasibility (study II), and only minor changes of the protocol were needed. There were no benefits for OEP or OEP+MI with personal support implemented nine times over the 12-month period. However, all groups maintained physical functioning and activity (study III). To increase physical functioning and reduce falls in this sub-group of older adults, more frequent personal support and/or an alternative delivery format may be required for efficient intensity and challenge in home exercises. Over 12 months, falls and fall-related injuries in the RCT sample were the most common when moving around within the home and transitioning from sitting to standing (study IV). Special attention to these activities might be important for preventing falls in community-dwelling older adults who need walking aids or home support.

- OBJECTIVE: To provide strategies to assist healthcare professionals in the area of rehabilitation to improve prevention of falls. DESIGN: A conceptual framework is described as a foundation for the proposal of 2 intertwined strategies, of intervention and implementation, which target the questions: Which strategies for intervention represent the current best evidence? and: How can these strategies be implemented and continuously developed? RESULTS: Strategies for multifactorial and multiprofessional fall preventive interventions are presented in terms of a "fall prevention pyramid model", including general, individualized, and acute interventions. A systematic global fall risk rating by the staff is recommended as an initial procedure. Fall event recording and follow-up are stressed as important components of local learning and safety improvement. Development of implementation strategies in 3 phases, focusing on interaction, facilitation and organizational culture, is described. CONCLUSION: A well-developed patient safety culture focusing on prevention of falls will, when successfully achieved, be seen by staff, patients and their significant others as being characteristic of the organization, and will be evident in attitudes, routines and actions. Moreover, it provides potential for positive side-effects concerning organizational and clinical improvements in additional areas.
