We begin by introducing the concept of dementia friendly, the policy context and what has already been evidenced via prior reviews and conceptual discussions. We conducted a systematic review following PRISMA guidelines, resulting in the inclusion of nineteen papers that reported on the methods and approaches used to involve people living with dementia in achieving dementia friendly or supportive care outcomes. Five primary themes were identified: the potential of group-based activities to facilitate inclusion and engagement; achieving engagement in decision making; the value of developing tools to help service providers to engage those living with dementia in care decisions; the role of awareness raising and education to support the inclusion of a range of stakeholders in achieving DF support and care outcomes; the need for cultural and contextual sensitivity when seeking to engage stakeholders to achieve positive care outcomes.

While it will be years until we fully understand the impact that this pandemic has exacted on the nursing workforce, early studies have found that nurses have been traumatized by this event and many intend to leave the profession This seismic event only further exacerbated an already vulnerable and strained nursing workforce that pre-existed worldwide prior to COVID-19. The pandemic also highlighted the many challenges facing nursing leadership, in particular, how to create conditions to maintain and sustain a healthy nursing workforce. Nurses' job satisfaction has emerged as an important predictor of whether nurses remain in an organization and stay in the profession. When examined more closely, job satisfaction has been related to nurses feeling empowered to exercise autonomy over their own practice and having agency. Autonomy and agency, in turn, are affected by their managers' leadership styles. Leaders are instrumental in setting the tone and creating the climate and culture that either values or devalues autonomy and agency. To help leaders create empowering conditions, we have developed a guide for leaders. This guide, based on the value-driven philosophy of leadership called Strengths-Based Nursing and Healthcare Leadership (SBNH-L), is founded on principles of person-centered, empowerment, relationship-focused, and innate capacities (ie, strengths) that are operationalized in eight core values. This guide can be used by leaders as their roadmap to create empowering workplace conditions that value and facilitate nurses' autonomy and agency.</p>","PeriodicalId":44346,"journal":{"name":"Journal of Healthcare Leadership","volume":"13 ","pages":"169-181"},"PeriodicalIF":4.4,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/61/0f/jhl-13-169.PMC8326221.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39275972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
