Strategies to implement multifactorial falls prevention interventions in community-dwelling older persons: a systematic review.

BACKGROUND: One-third of the community-dwelling older persons fall annually. Guidelines recommend the use of multifactorial falls prevention interventions. However, these interventions are difficult to implement into the community. This systematic review aimed to explore strategies used to implement multifactorial falls prevention interventions into the community. METHODS: A systematic search in PubMed (including MEDLINE), CINAHL (EBSCO), Embase, Web of Science (core collection), and Cochrane Library was performed and updated on the 25th of August, 2022. Studies reporting on the evaluation of implementation strategies for multifactorial falls prevention interventions in the community setting were included. Two reviewers independently performed the search, screening, data extraction, and synthesis process (PRISMA flow diagram). The quality of the included reports was appraised by means of a sensitivity analysis, assessing the relevance to the research question and the methodological quality (Mixed Method Appraisal Tool). Implementation strategies were reported according to Proctor et al.'s (2013) guideline for specifying and reporting implementation strategies and the Taxonomy of Behavioral Change Methods of Kok et al. (2016). RESULTS: Twenty-three reports (eighteen studies) met the inclusion criteria, of which fourteen reports scored high and nine moderate on the sensitivity analysis. All studies combined implementation strategies, addressing different determinants. The most frequently used implementation strategies at individual level were "tailoring," "active learning," "personalize risk," "individualization," "consciousness raising," and "participation." At environmental level, the most often described strategies were "technical assistance," "use of lay health workers, peer education," "increasing stakeholder influence," and "forming coalitions." The included studies did not describe the implementation strategies in detail, and a variety of labels for implementation strategies were used. Twelve studies used implementation theories, models, and frameworks; no studies described neither the use of a determinant framework nor how the implementation strategy targeted influencing factors. CONCLUSIONS: This review highlights gaps in the detailed description of implementation strategies and the effective use of implementation frameworks, models, and theories. The review found that studies mainly focused on implementation strategies at the level of the older person and healthcare professional, emphasizing the importance of "tailoring," "consciousness raising," and "participation" in the implementation process. Studies describing implementation strategies at the level of the organization, community, and policy/society show that "technical assistance," "actively involving stakeholders," and "forming coalitions" are important strategies.

Effect of Repeated Whole Blood Donations on Aerobic Capacity and Hemoglobin Mass in Moderately Trained Male Subjects: A Randomized Controlled Trial.

BACKGROUND: The aims of the present study were to investigate the impact of three whole blood donations on endurance capacity and hematological parameters and to determine the duration to fully recover initial endurance capacity and hematological parameters after each donation. METHODS: Twenty-four moderately trained subjects were randomly divided in a donation (n = 16) and a placebo (n = 8) group. Each of the three donations was interspersed by 3 months, and the recovery of endurance capacity and hematological parameters was monitored up to 1 month after donation. RESULTS: Maximal power output, peak oxygen consumption, and hemoglobin mass decreased (p < 0.001) up to 4 weeks after a single blood donation with a maximal decrease of 4, 10, and 7%, respectively. Hematocrit, hemoglobin concentration, ferritin, and red blood cell count (RBC), all key hematological parameters for oxygen transport, were lowered by a single donation (p < 0.001) and cumulatively further affected by the repetition of the donations (p < 0.001). The maximal decrease after a blood donation was 11% for hematocrit, 10% for hemoglobin concentration, 50% for ferritin, and 12% for RBC (p < 0.001). Maximal power output cumulatively increased in the placebo group as the maximal exercise tests were repeated (p < 0.001), which indicates positive training adaptations. This increase in maximal power output over the whole duration of the study was not observed in the donation group. CONCLUSIONS: Maximal, but not submaximal, endurance capacity was altered after blood donation in moderately trained people and the expected increase in capacity after multiple maximal exercise tests was not present when repeating whole blood donations.
