Using a systematic review to uncover theory and outcomes for a complex intervention in health and social care: a worked example using life story work for people with dementia

Life Story Book to enhance communication in persons with dementia: A systematic review of reviews

The Life Story Book has been commonly used in promoting person-centred care in older adults, especially for persons with dementia. This involves collecting the life stories and memories of the person living with dementia and compiling them into a book or folder, which is used by staff or family to assist the person recall these memories. Evidence on the use, benefits and influences of the Life Story Book in dementia care is limited. This systematic literature review aimed to collect past reviews and provide a thorough overview of the use, benefits, and impact of the Life Story Book for the person with dementia, the relatives, family, and caregivers. The electronic databases PubMed, Scopus, Science Direct and Web of Science as well as grey literature through Google Scholar were searched to select the relevant studies. Seven studies that meet the inclusion criteria were selected and data synthesised. Findings revealed that the use of the Life Story Book has no specific guidelines and has been described with numerous characteristics and varied implementation methods. The Life Story Book intervention is found to provide positive outcomes for the person with dementia and the carers involved. Six out of the seven studies reported that Life Story Book enhanced communication between persons with dementia, relatives, care staff, and residents. The review extends the current evidence on the usage of the Life Story Book in dementia care and confirms that the use of life stories leads to better care in various settings. However, more research is needed to reveal the potential of the Life Story Book in enhancing communication. Guidelines and training are also required to make the best use of the Life Story Book.

Effectiveness of the Biography and Life Storybook for Nursing Home Residents: A Quasi-Experimental Study

There are currently limited studies that have examined the use of the biography and life storybook (BLSB) among the Asian older adult populations in the long-term care setting. This quasi-experimental study aimed to examine its impact on life satisfaction scores, depression, and quality of life among nursing home residents in Singapore. Two wards were assigned to either the intervention or control group. The intervention group was assigned to the BLSB intervention, which comprised eight nurse-facilitated structured sessions over three months and their usual daily activities, whereas the control group was assigned to the routine activities. A total of 74 nursing home residents completed the study, with 37 in each group. The BLSB intervention improved depression, quality of life, and life satisfaction for nursing home residents in Singapore, with significant results observed across all three outcomes over the 3-month period. The study findings support the use of BLSB as an effective reminiscence-based intervention for older adults in an Asian nursing home setting.

Methods for the health technology assessment of complex interventions: a protocol for a scoping review

INTRODUCTION

In healthcare policy and economic literature, research on the health technology assessment (HTA) of complex interventions (CIs) is becoming increasingly important. In many developed countries, HTA guides decision-making to help achieve greater value for money when funding health care. However, research has yet to identify the forms of evidence and evaluation criteria that should be used in the HTA of CIs. Previous research has established that the HTA of CIs requires multiple factors to be evaluated but there is no agreement on which factors ought always to be considered. There is equally little agreement on which forms of evidence ought to be collected or synthesised and how. We plan to perform a systematic scoping review in order to identify the range of evaluation criteria and types of evidence currently used in the HTA of CIs.

METHOD AND ANALYSIS

This protocol was developed to guide the methodological framework for the conduct of a scoping review on health technology assessment (HTA) of complex interventions (CIs), using the Joanna Briggs Institute guidelines and the six-stage framework proposed by Arksey and O'Malley, in addition to more recent innovations in scoping review methodology. A grey literature search will supplement the primary searches of seven electronic databases for studies available in English between January 2000 and August 2020. Two reviewers will independently screen all search results for inclusion and data will be extracted using a customised data extraction or charting form. Any dispute will be resolved by consensus or through arbitration by a third author. The mnemonic Population, Concept and Context will be adopted to establish criteria for selecting relevant literature, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: Extension for Scoping Review will be used for reporting the results. Several explanatory-descriptive methods will be used for analysing the extracted data including frequency and trend analyses as well as reflexive thematic coding and analysis.Mapping evidence on the HTA of CIs will allow us to gain a better understanding of both established and emerging practices, including the information types, requirements, values and parameters that are incorporated in the HTA of CIs. We also expect the findings of the scoping review to help identify research gaps that will guide future studies. As healthcare becomes more complex in its delivery, it is timely to determine how these complex interventions should be assessed so that policy decisions can be made about whether implementation and public funding is warranted.

ETHICS AND DISSEMINATION

This scoping review will involve secondary analysis of already collected data, and thus, does not require ethics approval. The research findings will be submitted to peer-reviewed journals for publication and will also be disseminated at conferences and seminars.
