Background A range of studies found that spending time outdoors in daylight provided substantial benefits for the psychosocial well‐being of older people. Good psychosocial well‐being is essential in maintaining overall health as people age and often contributes to adequate physical functioning. Objectives The overall objective of this study was to undertake a systematic review on the effects of spending time outdoors in daylight on the psychosocial well‐being of older people and their family carers. Inclusion criteria Types of participants This review considered studies that included older people aged 55 years or more, including those living in a community or residential accommodation setting. In addition, this review considered family carers, who were defined as unpaid relatives or friends of an older person, who helped that individual with their activities of daily living. Types of intervention(s) The intervention of interest was spending time outdoors in daylight. Types of studies All experimental and epidemiological study designs including randomized controlled trials and non‐randomized controlled trials published in the English language were included in this review. Types of outcomes This review considered studies that included objective and/or subjective measures of psychosocial well‐being for older people and their family carers. Search strategy The search aimed to find published and unpublished studies through electronic databases, reference lists, key reports and the World Wide Web. An extensive search was undertaken for the following databases: MEDLINE, CINAHL, Wiley Online Library, ProQuest Central, Scopus, and the Cochrane Library. Databases were searched up to December 2013. Methodological quality Methodological quality was assessed independently by three reviewers using the Joanna Briggs Institute Meta‐Analysis of Statistics Assessment and Review Instrument (JBI‐MAStARI) checklists. Disagreements that arose between the reviewers were resolved through discussion. Data collection Quantitative data were extracted from papers included in the review using the standardized data extraction tool from JBI‐MAStARI. The data was individually extracted by two reviewers. Disagreements that arose between the reviewers were resolved through discussion. All results were subject to double data entry. Data synthesis For this review statistical pooling of the data was not possible due to the heterogeneity of the studies; therefore, the findings are presented in narrative form. Results A total of 13 studies were included in the final review. In the four studies that evaluated the effects of exposure to daylight on behavioral disturbances, there was no evidence of effect of daylight hours on physical and verbal aggression. There was some evidence to indicate that exposure to daylight for a period of time resulted in fewer depressive symptoms. Increasing the frequency of going outdoors was associated with better cognitive preservation over a one year period. Similarly exposure to daylight resulted in improved social functioning and improved quality of life. There were no studies that evaluated the effect of spending time outdoors in daylight on the psychosocial well‐being of family carers, including carer satisfaction or carer stress. Conclusions There is insufficient high‐quality evidence from which conclusions can be drawn for the effect of spending time outdoors in daylight on the psychosocial well‐being of older people and their family carers. More robust research is required to evaluate the effectiveness of interventions to improve time spent outdoors in daylight for older people and their family carers. Implications for practice There is some evidence to support the effects of exposure to daylight on mood, cognition and social functioning levels. With only small changes in routines for nursing staff there is potential for exposure to sunlight to have a significant impact on psychosocial well‐being for older adults living in residential accommodation. Implications for research Future studies should be undertaken using more rigorous research designs, such as randomized controlled trials with sufficiently powered sample sizes. A focus on accurately measuring time spent outdoors in daylight should be a priority. Additionally, by investigating a comprehensive range of psychosocial outcomes with validated tools, researchers could more accurately deduce the effect of spending time outdoors on the psychosocial well‐being of older people and family carers.

Background Health services provide clinical training to medical, allied health and nursing staff. Ensuring the quality and quantity of this training is critical to workforce supply. Health Workforce Australia (HWA) has funded initiatives to enhance clinical training quality and the availability of clinical training placements. The quantity and quality of clinical placements must be increased. While there are many strategies to improve quantity and many strategies claim to enhance quality, there is an absence of agreed measures to evaluate placement quality. A standardised, comprehensive and widely applicable measure of clinical education placement quality is required. This study describes the challenges involved in constructing a systematic review search strategy.
