A systematic review of the provision and efficacy of patient and carer information and support (PCIS) interventions for patients with dementia and their informal carers

Abstract

Background The NHS dementia strategy identifies patient and carer information and support (PCIS) as a core component of gold-standard dementia care. This is the first systematic review of PCIS, performed to analyse the literature and evidence for these interventions. Aims To systematically review literature evaluating the effectiveness of the provision of PCIS for people with dementia and their informal carers, in inpatient and outpatient settings. Methods Searches of four online biomedical databases, accessed in September 2018. Studies were selected if they were: relating to people with dementia or their informal carers, based in inpatient or outpatient settings, published in Englishlanguage peer-reviewed journals no earlier than the year 2000 and assessed dementia-related information or social support interventions, by measuring qualitative or quantitative carer or patient-reported outcomes. Standardised data extraction and quality appraisal forms were used. Results 7 of 43 full-text papers analysed were eligible for analysis. 3 papers were different arms of one original study. Trends were present in the quantitative results towards reduced patient and carer depression and anxiety and the themes in the qualitative analysis were in favour of the intervention. Conclusions The studies analysed were too heterogeneous in design, population and outcomes measured to make a conclusive opinion about the efficacy of these interventions. It is surprising that for such a common condition, a gold-standard evidence-based intervention and standardised delivery for provision of PCIS for people living with dementia in the UK does not exist. Further research is therefore vital.

Neglected Needs of Family Caregivers during the COVID-19 Pandemic and What They Need Now: A Qualitative Study

“…Yet family caregivers were marginalized by healthcare systems and procedures [7][8][9]. Recent reviews also recognize that effective support interventions for family caregivers exist but are rarely translated into widespread practice [4,8,10,11]. These reviewers stressed that, with a rapidly growing population of older adults, effective caregiver supports must be developed to deal with the higher demands that family caregivers are expected to fulfil.…”

Effectiveness of interventions designed to mitigate the negative health outcomes of informal caregiving to older adults: an umbrella review of systematic reviews and meta-analyses

“…Manifestations of lack of patient-centredness affected care receivers not only during the period of respite, but also after the respite, as it took some time for care receivers to recover. Along the same lines, Miles et al 82 indicated that caregivers were positive towards the use of patient and caregiver information and support services but suggested that ‘there is not a one-size-fits-all approach which can be used, as every patient […] and their carers will have different needs, preferences and responses’.…”

“…Although the included reviews covered studies with varying designs and heterogeneous interventions, we found similarities in the description of the determinants of perceived caregiver acceptability. First, seven reviews spanning almost all intervention types demonstrated that the person-centeredness, flexibility and personalisation of the interventions promoted higher acceptability as expressed by caregivers 33 34 46 60 66 81 82. Caregivers appreciated if interventions were able to accommodate their lifestyles and needs 33 34 46 66 81.…”

Assessing psychosocial interventions for informal caregivers of older people with early dementia: a systematic review of randomized controlled evidence

“…Well-established evidence emphasized the great benefits of timely support for informal caregivers of older people with early dementia [71]. One recent systematic review also reported that informal caregivers of people with dementia felt it was the right time to receive information and support directly after or at the time of diagnosis [72].…”
