Abstract
As people age, they often need home modifications to remain living in the community. This review sought to identify outcomes from home modifications for adults aged ≥50 years living in the community and their family carers. Peer-reviewed literature was reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR). Five databases were search (Ageline, CINAHL, Emcare, Medline, Scopus) from 2011 to 2023. N = 38 articles meeting the criteria. Sixteen outcomes were identified (14 positive, two negative) including reduction in falls and falls risk and enhanced quality of life. In addition, five outcomes for family carers were identified (all positive). Only four studies reported costs of home modifications installed. Home modifications can provide substantial benefit to adults aged ≥50 years, supporting their independence and allowing them to remain in their own home.
Plain Language Summary
As people get older, they sometimes need some changes to their home such as handrails, ramps, and stair lifts. We looked at published papers to see what outcomes people have when they make these types of changes to their homes. We found 19 positive outcomes for people aged 50 years and over and the family members who care for them, such as fewer falls and less pain for older people, and better quality of life for older people and their family carers. We also found two negative outcomes. Some people experienced stigma from having home modifications and did not like the way the changes to their home looked. Overall, home modifications can support people to stay in their home and be as independent as possible.

Introduction
Older adults often prefer to remain in their own homes as they age rather than moving into residential aged care (Ratnayake et al., 2022). However, remaining safe and independent at home is not always possible without home modifications, which range from minor (such as rails) to extensive (e.g., bathroom redesign), and include recommendations such as decluttering and improved lighting (Stark et al., 2009). Falls at home are costly to health care systems internationally (Australian Institute of Health and Welfare [AIHW], 2022; Burns et al., 2016; Center for Research Excellence—Prevention of Fall Injuries, n.d.; Haddad et al., 2024) and a major reason why older adults move temporarily or permanently into residential aged care (Collins & Casey, 2019; Craig et al., 2013; Gill et al., 2013).
The cost of home modifications can vary widely from an estimated AU$150 to $200 for a grabrail to several 1000$ for extensive bathroom renovations. Internationally, there are a variety of approaches to support services to enable people to stay at home, which can be government subsidized, grant-based or privately funded. For example, in Australia, as in other developed nations, older adults (aged 65 years and over) can access government supports to remain at home, including the provision of home modifications (Department of Health and Aged Care, 2024). Adults aged 50 to 64 years might seek home modifications due to multimorbidity reducing physical functioning and may be eligible for funding through disability support provisions or other community-based programs. Alternatively, they may self-fund modifications to futureproof their homes for aging in place. Given the cost of funding home modifications and the reasonable expectation that expenditure will continue to increase in the future due to an aging population in developed nations such as Australia, the United States and United Kingdom (Australian Bureau of Statistics [ABS], 2023; Barton et al., 2024; Schaeffer, 2024) it is important for funders and self-funders to understand what outcomes result from investment in home modifications. No review has synthesized this data to date.
Other reviews have been conducted on the topic of home modifications, but none have sought to broadly identify the outcomes from home modifications for adults aged 50 years and over and their family carers. Previous reviews have been limited by methodological approaches (such as only randomized controlled trials e.g., Sheth & Cogle, 2023) or only qualitative studies (Aclan et al., 2023), focused only on consumers (i.e., those whose homes have been modified) with a particular health condition (such as Alzheimer’s disease e.g., Struckmeyer & Pickens, 2016), or a narrow range of outcomes, such as only falls (Chase et al., 2012) or accessibility (Cho et al., 2016; Struckmeyer et al., 2021). Another review included outcomes from home modifications for adults with disability and older adults’ but focused on health-related outcomes and caregiving, rather than broader psychosocial outcomes (Stark et al., 2017) and another review focused only on home automation (Cleland et al., 2024).
The Current Study
This scoping review seeks to identify outcomes from home modifications for adults aged 50 years and over living in the community, and their family carers.
Method
This scoping review was conducted using the five-stage approach outlined by Arksey & O’Malley (2005): identifying the research question, identifying relevant studies, study selection, charting the data, collating, summarizing the reporting the results. We used the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) (Page & Moher, 2017; Tricco et al., 2018). A protocol for this scoping review is available in Open Science Framework (George et al., 2024).
Stage 1: Identifying the Research Question
As outlined in the literature review, a gap exists in identifying and collating the outcomes from home modifications for adults aged 50 years and over. As identified in Arksey & O’Malley (2005) it is important to define terms when setting the research question for a scoping review. This review sought to include peer-reviewed literature reporting outcomes from home modifications for adults aged 50 years and over living in the community; that is, living in their own home (owned or rented) as opposed to a residential care home. Both healthy and participants with existing disability (any physical or cognitive impairment) were included. The review includes any low-tech modification. Low-tech modifications can range from minor modifications, such as rails, which are easy to install, relatively affordable and may meet a singular consumer need, to more substantial and costly modifications, such as the redesign of a bathroom. Such a modification is more complex as well as more costly, would take longer to implement, likely require the employment of several trades to accomplish, and may need to meet professional standards or guidelines relative to the jurisdiction. A complex home modification of this sort may require more consultation with the consumer and aim to meet multiple consumer needs. Modifications operated by technology, such as home automation modifications were excluded from this review. Any primary research study design was included. Included articles had to report at least one outcome which is related to the individual and/or family member (residing or non-residing).
Outcomes from modifications in community care homes, residential aged care homes and supported accommodation facilities were excluded. The review excluded articles on smart home technologies. Studies not published in English, theses/dissertations, reviews, editorials, opinion pieces and conference abstracts and papers were also excluded.
Stage 2: Identifying Relevant Studies
The following five databases were searched: Ageline, CINAHL, Emcare, Medline and Scopus. A search strategy was developed by the authorship team with support from a Research Librarian. The search strategy included terms for home (dwelling, residential), modification (adjustment, adaptation, accessibility), and age (≥50 years, middle aged, older). Once agreed for Medline, the search strategy was translated for the other databases, with the Research Librarian conducting all database searches. The review included articles published from July 2011 to December 2023.
Stage 3: Study Selection
Articles identified were imported into Covidence software (Veritas Health Innovation, 2021) where duplicates were removed. Two authors (CH and HB) independently conducted all title and abstract screening, with conflicts resolved via discussion. Five authors participated equally in full text screening, screening 35 to 36 articles each (CH, HB, AD, CG and SG), with each article being double screened. As before, any conflicts were resolved by discussion.
The following data were extracted: title, author, year of publication, country, study aims, study design, study population (age, gender), sample size, home modification type(s), cost of modifications, outcome identified, and how outcomes were measured. Data were extracted by four authors (CH, HB, AD, CG). The lead author checked data extraction for all articles to ensure that the template was being consistently and accurately applied.
Stage 4: Charting the Data
Chartering the data is the stage where data is synthesized and interpreted. Data was synthesized using a thematic approach with included articles imported into NVivo to support the analysis. Initial codes (outcomes) were identified by the first author (CH). At a workshop attended by all authors, the initial outcomes codes were presented and discussed. This led to some outcomes being consolidated and some split to form separate outcomes. For example, the initial outcome code of “reduced falls and fear of falling” was split into separate outcomes as falls is a physical outcome potentially causing a health event, whereas fear of falling is psychological. The initial code of “enhanced confidence” was merged with “enhanced ability to perform ADLs” as it was these tasks that consumers expressed confidence in performing following the installation of home modifications. Some codes were renamed slightly for consistency of wording across the themes. Full details of initial codes and final codes are shown in Supplementary Information.
Stage 5: Collating, Summarizing and Reporting the Results
Following the workshop, the revised codes were circulated to the authorship team for final approval. The team approved the final list with no further changes. Following this, the first author entered the data extracted on study characteristics into a table and collated the themes (outcomes) for each by study based on the agreed final thematic codes. Outcome measures were included where reported.
Results
A total of 3370 records were identified across the five database searches. With 1,724 duplicates identified by Covidence and 62 identified manually, this resulted in 1,584 articles being screened at the title and abstract stage, and 89 articles being screened at the full text stage. Thirty-eight articles were included in this review (Figure 1).

PRISMA-ScR Flowchart.
Study Characteristics
Of the 38 articles, most studies were conducted in the United Kingdom (n = 8), United States (n = 8) and Australia (n = 5), with two each in New Zealand, Brazil, Japan, Sweden, and Turkey, and one each in Belgium, Spain, India, Iran, Switzerland, Taiwan, and Thailand. Two papers reported on different aspects of a New Zealand study, with one paper reporting the findings of the whole study population (Keall et al., 2017), and the other paper reporting findings related to an indigenous population sub-sample (Keall et al., 2021). Three papers reported on the BATH-OUT study, with one paper focusing broadly on the findings of the feasibility randomized controlled trial (RCT) study (Whitehead et al., 2018), one paper on the qualitative findings (Whitehead & Golding-Day, 2019) and one paper reporting on the extended follow-up study (Golding-Day & Whitehead, 2020) (Table 1).

The majority of studies were quantitative (n = 25, 66%), with seven studies using mixed methods approaches (18%), and six studies adopting qualitative methodology (16%). Samples of adults aged 50 years and over varied from a sample of one person (a case study, Mani, 2019) to 657,536 (Hollinghurst et al., 2022). Eighteen studies (47%) included data from adults with and without modifications to compare outcomes (Ahn & Hegde, 2011; Chandola & Rouxel, 2022; Chindapol & Arkarapotiwong, 2023; Cockayne et al., 2021; Dalvand et al., 2024; De-Rosende-Celeiro et al., 2019; Hollinghurst et al., 2022; Hwang et al., 2011; Keall et al., 2017, 2021; Liu et al., 2021; Maggi et al., 2018; Mitoku & Shimanouchi, 2014; Ng et al., 2022; Sheffield et al., 2013; Tsuchiya-Ito et al., 2023; Whitehead et al., 2018; Whitehead & Golding-Day, 2019).
Most studies focused on older adults (60 years and over, or 65 years and over) but six papers relating to five studies reported lower mean ages and included younger adults (Ainsworth et al., 2023; Aplin et al., 2015; DeArajo et al., 2018; Keall et al., 2017, 2021; Pettersson et al., 2012). Four studies included carers as well as consumers (Ainsworth et al., 2023; Aplin et al., 2015; Golding-Day & Whitehead, 2020; Whitehead & Golding-Day, 2019). Golding-Day and Whitehead’s (2020) provided no socio-demographic details on the carers included in the study although the presented quotes suggest that they were family members rather than paid carers. The other three studies were reported to be exclusively or mostly family members or spouses/partners of the home modification users. Three studies collected data from carers only (DeArajo et al., 2018; Yang et al., 2021; Yeni & Yilmaz, 2022). In DeArajo and colleagues study most (72.7%) of carers were reported to be spouses or family members and the other two studies included only family carers.
Types of Home Modifications
Six papers focused exclusively on bathrooms modifications, including the three papers from the BATH-OUT study (Ahn & Hegde, 2011; De-Rosende-Celeiro et al., 2019; Golding-Day & Whitehead, 2020; Korp et al., 2012; Whitehead et al., 2018; Whitehead & Golding-Day, 2019), whereas the rest of the papers included modifications to various areas of the home, with two studies also including modifications to outdoor as well as indoor areas (Hwang et al., 2011; Liu et al., 2021). A wide range of in-home modifications were included such as grab bars/rails, widened doorways, ramps, re-swung internals doors, fold down seat in shower, taps altered/lever taps, relocation of power points, lighting improvements, balustrading, raising toilet, bed raisers, handheld shower, bathtub railings, eliminating floor height differences, brighter lightbulbs, and anchoring furniture. Some studies included modifications that did not include purchasing any products, such as alterations to furniture and equipment placement and decluttering (Dalvand et al., 2024; Mani, 2019). Studies considering modifications to outdoor areas, included concrete pads to clotheslines, path modifications, extra steps to front doors, improved outdoor lighting, slip resistant edges to outdoor steps, slip resistant ground surfaces, and automatic garage door openers.
Cost of Home Modifications
A small number of studies specified the costs of home modifications included in their study. Van Oss et al. (2012) reported that all modifications made were below $500. In another U.S. study, Washington et al. (2023) reported that the average expenditure across 31 participants was $1885, while a Japanese study reported that the maximum spend per person on modifications was $1513 per home (Tsuchiya-Ito et al., 2023). A study conducted in the United Kingdom where all older adults had bathroom renovations reported the average spend across 60 participants was £4878 (Whitehead et al., 2018).
Outcomes for Adults Aged 50 Years and Over
Across the studies we identified 16 outcomes for adults aged 50 years and over, of which 14 were positive and two were negative, and five outcomes for family carers (Table 2).
Summary of Home Modification Outcomes.
Reduction in Falls and Falls Risks
Fifteen studies (39%) reported a reduction in fall or falls risk (Aitken et al., 2023; Chandola & Rouxel, 2022; Chindapol & Arkarapotiwong, 2023; Cockayne et al., 2021; Dalvand et al., 2024; Gürler & Bayraktar, 2021; Hollinghurst et al., 2022; Keall et al., 2017, 2021; Korp et al., 2012; Liu et al., 2021; Maggi et al., 2018; Ng et al., 2022; Sheffield et al., 2013; Yeni & Yilmaz, 2022). For example, Chandola and Rouxel (2022) reported a 3% reduction in falls, and Chindapol and Arkarapotiwong (2023) reported a reduction in falls risk of 52%. A cost-benefit analysis of an RCT study to reduce falls noted a 33% drop in costs associated with home falls (Keall et al., 2017). Dalvand and colleagues (2024) reported a reduced risk of falling between baseline and follow up for those who had home modifications, but that comparing falls risk between the intervention group and control group was not significant. Notably, three studies reported that home modifications did not reduce falls (Cockayne et al., 2021; Korp et al., 2012; Ng et al., 2022).
Reduced Fear of Falling
Four studies (11%) identified reductions in the fear of falling (Crowell & Sokas, 2020; Golding-Day & Whitehead, 2020; Schorderet et al., 2022; Sheffield et al., 2013) with Schorderet et al. (2022) observing a 12.5% reduction in the fear of falls following the implementation of home modifications.
Enhanced Ability to Safely Perform Activities of Daily Living (ADLs)
Fifteen studies (39%) reported that home modifications improved consumers ability to safely perform ADLs (Ahn & Hegde, 2011; Ainsworth et al., 2023; Aitken et al., 2023; Aplin et al., 2015; De-Rosende-Celeiro et al., 2019; Golding-Day & Whitehead, 2020; Lau et al., 2018; Pettersson et al., 2012; Schorderet et al., 2022; Sheffield et al., 2013; Thordardottir et al., 2020; Torres et al., 2022; Van Oss et al., 2012; Washington et al., 2023; Whitehead & Golding-Day, 2019), most commonly showering/bathing independently (Aplin et al., 2015; Golding-Day & Whitehead, 2020; Thordardottir et al., 2020; Whitehead & Golding-Day, 2019) though the restoration of other previous activities included cooking (Aitken et al., 2023), doing laundry (Aitken et al., 2023), and gardening (Aplin et al., 2015).
A mixed methods study reported a 93.4% reduction in difficulties carrying out ADLs (Schorderet et al., 2022), while Aplin et al. (2015) reported a greater sense of safety and reduced anxiety and fear in performing daily activities. Five studies specifically reported an increase in confidence in the performance of ADLs (Aitken et al., 2023; Aplin et al., 2015; Golding-Day & Whitehead, 2020; Thordardottir et al., 2020; Whitehead & Golding-Day, 2019). A qualitative study conducted in the United Kingdom found that, due to finding it easier to bathe, consumers felt clean and were able to be in the company of others without feeling embarrassed about potential body odor (Aitken et al., 2023). Similarly, another study reporting that consumers were able to groom and present themselves in their preferred manner (Thordardottir et al., 2020).
Enhanced Access to the Community and Social Engagement
Seven studies (18%) identified enhanced community access and social engagement from the use of home modifications (Aitken et al., 2023; Aplin et al., 2015; Chandola & Rouxel, 2022; De-Rosende-Celeiro et al., 2019; Golding-Day & Whitehead, 2020; Liu et al., 2021; Pettersson et al., 2012). For example, in a study conducted in the United States, Liu and colleagues (2021) identified a significant improvement on the variable “leaving the house for any reason other than health.” Aplin et al. (2015) identified that being able to exit the house more easily led to being able to walk in the neighborhood for those that were mobile, with or without walking aids. Two studies specifically reported that home modifications increased accessibility for visitors (Aitken et al., 2023; Aplin et al, 2015), including for friends with mobility issues (Aitken et al., 2023). Supporting visitors to enter homes had a positive knock-on positive effect on consumers levels of social engagement (Aplin et al., 2015).
Enhanced Emotional Well-Being and Mental Health
Seven studies (18%) identified enhanced emotional well-being as an outcome from home modifications (Ainsworth et al., 2023; Aitken et al., 2023; Aplin et al., 2015; Golding-Day & Whitehead, 2020; Schorderet et al., 2022; Washington et al., 2023; Whitehead et al., 2018). For example, qualitative studies identified reduced depression, anxiety, and frustration, along with more happiness and improved self-esteem (Aitken et al., 2023), and greater peace of mind and fewer negative thoughts (Ainsworth et al., 2023).
Supports Remaining at Home
Six studies (16%) reported that home modifications supported older adults to remain in their own home (Ahn & Hegde, 2011; Aitken et al., 2023; Aplin et al., 2015; Golding-Day & Whitehead, 2020; Hwang et al., 2011; Pettersson et al., 2012). In their U.K. based study, Hwang et al. (2011) reported that having home modifications was a significant variable in predicting aging in place. A U.S. based study reported that home modifications increased consumers level of satisfaction with their home and their perception of the capacity of the home to meet future needs (Ahn & Hegde, 2011).
Enhanced Quality of Life
Six studies (16%) reported that home modifications were associated with an increase in consumers quality of life (Carnemolla & Bridge, 2016; Mani, 2019; Schorderet et al., 2022; Sheffield et al., 2013; Whitehead et al., 2018; Whitehead & Golding-Day, 2019). A Swiss study reported a 9.8% improvement in quality of life scores after receiving home modifications (Schorderet et al., 2022). An Australian study reported an overall enhancement of quality of life and that the biggest change was that related to a dimension on independent living, which showed a 16% increase (Carnemolla & Bridge, 2016).
Enhanced Physical Health
Six studies (16%) reported that home modifications enhanced physical health (Ainsworth et al., 2023; Aitken et al., 2023; Chandola & Rouxel, 2022; Mani, 2019; Mitoku & Shimanouchi, 2014; Whitehead et al., 2018). For example, Ainsworth and colleagues (2023) reported that home modifications improved physical strength, control over body temperature, and enhanced mobility. An Indian case study reported that home modifications resulted in reduced fatigue (Mani, 2019), while a Japanese study observed a reduction in the progression of frailty, and a halving of the risk of mortality for those with older adults with home modifications compared with those without (Mitoku & Shimanouchi, 2014).
Reduction in Pain
Three studies (8%) identified a reduction in pain as a result of home modifications (Ainsworth et al., 2023; Chandola & Rouxel, 2022; Mani, 2019). For example, one study reported that home modifications provided relief from pain and exertion (Ainsworth et al., 2023) whereas another study reported that pain reduced by 6% (Chandola & Rouxel, 2022).
Reduced Need for Formal and Informal Care
Three studies (8%) identified a reduced need for formal (paid) carers (Aitken et al., 2023; Carnemolla & Bridge, 2019; Tsuchiya-Ito et al., 2023). Aitken et al. (2023) identified that formal care was reduced or withdrawn altogether and that, where formal care continued, it was less intense in nature. Carnemolla and Bridge (2019) identified a mean reduction in care of 0.36 hrs per week in their Australian study, whereas a Japanese study identified significantly lower care needs deterioration in older adults with home modifications compared with those without modifications.
Two studies (5%) identified a reduction in the need for informal care (i.e., care provided by family members or others without payment) (Aitken et al., 2023; Carnemolla & Bridge, 2019), with one study noting a significant mean reduction in informal care of 6 hrs per week (Carnemolla & Bridge, 2019).
Enhancement of Property
Two studies (5%) identified perceptions by consumers that their home modifications enhanced the value of their property (Aitken et al., 2023; Aplin et al., 2015). Although, as identified in the negative outcomes section below, not all consumers felt that modifications enhanced their property or its value.
Other Positive Outcomes for Adults Aged 50 Years and Over
One study (3%) reported the outcomes of reduced need to excessively plan (Golding-Day & Whitehead, 2020, and enhanced accessibility (Liu et al., 2021), with consumers being able to access more of their house as well as outdoor areas. One study reported that consumers experienced enhanced comfort due to being less tired washing, having more space, and perceptions that their space was now more practical for their current and future needs (Schorderet et al., 2022).
Negative Outcomes for Adults Aged 50 Years and Over
In terms of negative outcomes for consumers, one study (3%) reported increased stigma related to needing home modifications (Aitken et al., 2023), and two studies (5%) reported a perceived negative impact on home aesthetics (Aitken et al., 2023; Aplin et al., 2015). In an Australian study, some consumers reported that the appearance of their home was related to their personal identity, and they didn’t like that their home now looked like a person with disability lived there or that it looked “like a hospital” (Aplin et al., 2015: 126).
Outcomes for Family Carers
The most common outcomes identified for family carers were reduced physical burden and enhanced safety which were identified by six studies (16%) (Ainsworth et al., 2023; Aitken et al., 2023; Aplin et al., 2015; DeArajo et al., 2018; Golding-Day & Whitehead, 2020; Whitehead et al., 2018). The studies identified less injury and deteriorating health from lifting and helping with self-care tasks of their care recipients (Ainsworth et al., 2023; Aitken et al., 2023). In a Brazilian study, DeArajo and colleagues observed a significant reduction in neck pain for family carers.
Two studies (5%) observed enhanced quality of life (DeArajo et al., 2018; Yang et al., 2021) and two studies identified reduced emotional burden for family carers (Golding-Day & Whitehead, 2020; Yang et al., 2021). One study (3%) identified improved family functioning due to a significant reduction in family conflict following the installation of home modifications (Yang et al., 2021). Finally, one study (3%) identified that family carers has more free time and flexibility as a result of their older family member having home modifications (Aitken et al., 2023).
Discussion
To date, there has been no review to consolidate the evidence of the outcomes derived from the use of home modifications for adults aged 50 years and over living in the community in their own homes (whether owned or rented). The aim of this review was to address this gap in the extant literature. This review has identified 21 outcomes from the use of home modifications for adults aged 50 years and over as well as for those caring for them. Most of the outcomes identified were positive, although a small number of studies identified negative outcomes (Aitken et al., 2023; Aplin et al., 2015).
Given the focus of many studies on falls prevention, it is not surprising that reduction to falls and falls risk were the most identified positive outcomes across the studies included in this review. Although we note contradictory evidence in that some studies found a positive association between home modifications and a reduction in falls (e.g., Aitken et al., 2023; Hollinghurst et al., 2022) and other studies found no such association (e.g., Cockayne et al., 2021; Korp et al., 2012). Raymond and colleagues (2018) note that occupational therapists prioritize older adults who have already fallen, whereas older adults themselves prioritized access to their home in seeking occupational therapy services. Despite these differences in priorities, it is clear that falls can be a significant issue as people age with declining physical functioning and increasing frailty which are costly to health services in Australia and internationally necessitating acute care as well as longer-term medical treatment (AIHW, 2022; Collins & Casey, 2019; NICE, 2013). Falls are also a significant factor in older adults temporary or permanent moving to residential aged care (Gill et al., 2013). Notably, providing services to older adults in the community rather than in residential aged care settings is not only significantly less costly (Mah et al., 2021), but also supports older adults’ preference for aging at home (Mulliner et al., 2020; Stones & Gullifer, 2016). This review provides evidence to practitioners that home modifications do not always result in a reduction in falls (Cockayne et al., 2021; Korp et al., 2012) and that a range of outcomes might be achieved from home modifications, including those prioritized by older people themselves, namely an ability to remain at home and greater access to inside and outside areas of their home (Raymond et al., 2018).
Indeed, home modifications were shown in several studies to directly or indirectly support older adults remaining at home (Ahn & Hegde, 2011; Golding-Day & Whitehead, 2020; Hwang et al., 2011). This was due to home modifications facilitating the safe navigation of the home environment, and supporting re-engagement with activities of daily living, as well as providing psycho-social outcomes such as reduced fear of falling, and enhanced confidence and emotional well-being (e.g., Aitken et al., 2023; Crowell & Sokas, 2020; Schorderet et al., 2022; Washington et al., 2023). Several studies also identified a reduction in the need for formal and informal care, which could be associated with significant savings, reduced burden and improved well-being for family carers, and increased privacy and independence for older adults (Aplin et al., 2015; Carnemolla & Bridge, 2019; Lau et al., 2018; Whitehead et al., 2018; Yang et al., 2021).
In this review only four studies reported any information relating to the cost of the home modifications undertaken (Tsuchiya-Ito et al., 2023; Van Oss et al., 2012; Washington et al., 2023; Whitehead et al., 2018). Although this data was relatively limited, it suggested that many home modifications are not costly to implement, with combinations of low-tech modifications shown as costing from below $500 (Van Oss et al., 2012) to an average of $1885 (Washington et al., 2023). More extensive home modifications were described in some studies and were more costly, at up to £4878 per home (Whitehead et al., 2018).
Some of the findings of our review aligned with that of other reviews on home modifications which were narrower in scope (only RCTs, only qualitative studies) or focused on a narrower population (e.g., people with Alzheimer’s disease) or different population (e.g., people with disabilities). For example, Aclan et al.’s (2023) qualitative review of home modifications for the same target population identified that home modifications supported independence and remaining at home. A review of home modifications for people with disabilities identified that home modifications improved physical function and reduced falls risk (Stark et al., 2017). Another review that focused on falls found a reduction in both falls and fear of falling (Chase et al., 2012). No review to date has captured the breadth of physical and psychosocial outcomes identified in the current review. However, we note that, as identified by Aclan and colleagues (2023), there was less evidence in relation to adults aged 50 to 64 years than adults aged 65 years and over and, when studies consisted of both age groups, there was no differentiation of experiences or outcomes on the basis of age.
This scoping review provides potentially valuable data to occupational therapists and others involved in prescribing and implementing home modifications as well as funders and policy makers. However, limitations of the review need to also be acknowledged. Although we targeted studies of home modifications for adults aged 50 years and over, some studies did not provide a lot of detail on the age of participants, therefore some studies were included in this review despite involving a small number of participants outside the target age range (e.g., Ainsworth et al. (2023) whose participants range in age from 24 to 93 years but with a mean of 62 years). As outlined above, studies that included those aged 50 to 64 years and 65 years and over, did not differentiate outcomes based on age or highlight any benefits associated with early intervention.
Due to resource constraints, we were not able to conduct consultation with stakeholders (adults aged ≥50 years and their family carers, funders, organizations providing home modifications) as recommended by Levac et al. (2010) to support interpretation of the findings prior to completing the write up of this review. However, the findings were discussed with our multi-disciplinary authorship team which includes academics with expertise in occupational therapy, physiotherapy, social gerontology, psychology, and health economics. Unlike systematic reviews, scoping reviews do not include an assessment of reporting quality. However, our review did focus only on peer-reviewed literature ensuring that article has been subject to critical review prior to publication.
Conclusions
This scoping review consolidates the evidence on the outcomes of home modifications for adults aged 50 years and over living in the community and their family carers, identifying a broad range of physical, and psychosocial benefits. While falls prevention was the most frequently cited positive outcome, the review also highlights the role of home modifications in promoting independence, enhancing emotional well-being, and reducing the need for formal and informal care. These findings reinforce the importance of home modifications in supporting aging in place, aligning with older adults’ preferences while also potentially reducing health care costs. However, contradictory evidence regarding falls reduction suggests the need for further research to clarify the conditions under which home modifications are most effective.
Despite its contributions, this review also identifies key gaps in the literature, including limited differentiation of outcomes based on age and a lack of cost-related data. Future research should explore the long-term economic impact of home modifications, particularly in relation to health care savings and carer burden reduction and examine their benefits for adults aged 50 years and over as a proactive strategy for aging. In addition, stakeholder consultation, including the perspectives of consumers and policymakers, could further contextualize these findings. Nonetheless, this review provides valuable insights for occupational therapists, health care professionals, and policymakers, supporting informed decision-making around home modification interventions for aging populations.
