Abstract

Coronavirus disease-2019 (COVID-19) had an unprecedented effect all over the world, especially in older individuals. The aim is to evaluate the social isolation, loneliness and quality of life of elderly individuals during the COVID-19 pandemic and to map suggestions to reveal and improve the current situation. This was a scoping review. Articles since December 2019 to March 2021 published on PubMed, Scopus, ProQuest, Cochrane Library, CINAHL databases with the following MeSh terms (‘COVID-19’, ‘coronavirus’, ‘quality of life’ ‘aging’, ‘older people’, ‘elderly’, ‘loneliness’ and ‘social isolation) in English were included. The research, by consensus, resulted in seven studies selected for full reading, including three descriptive and cross-sectional studies, a quasi-experimental study, a pre-post pilot program, an editorial note and a correspondence. In generally, these recommendations were grouped as evaluating the current state of loneliness and isolation in elderly people, making more use of technology opportunities, using cognitive behavioral therapies and different individual intervention components.

Keywords: COVID-19, Elderly, Isolation, Loneliness, Quality of life

Introduction

The COVID-19, which was declared as an epidemic by the World Health Organization (WHO) on March 11, 2020, caused great concern all over the world; it spread rapidly, affecting more than 223 countries and regions.1, 2, 3 In this pandemic disease, older people (especially older than 80 years old) are at higher risk of mortality.4 While 80% of deaths in the US are among adults aged 65 and over5, more than 95% in Europe and about 80% in China include those over 60.6 , 7 Therefore, health strategies such as quarantine and social distancing are important in the elderly to prevent the spread of coronavirus.8, 9, 10

The risk of developing a serious and often deadly disease has led to numerous restrictions in many countries that can have a detrimental effect on the psychological functioning of the elderly.11 However, with these restrictions, limited contact with other people can lead to the loss of social support, which is especially important for older people.12 , 13 Also, social isolation may result in loneliness, which is a factor significantly associated with depression in the elderly.14 Recent cross-sectional studies have reported higher levels of loneliness during the COVID-19 pandemic.15 In a study, it was stated that loneliness increased significantly among Dutch older adults during the epidemic compared to the end of 2019.16 Loneliness, which is a subjective condition that can be felt even in the presence of others17, has no different effects than objective social isolation measures.18 Loneliness is a strong risk factor for the development of a number of health conditions, such as coronary heart disease and stroke19, and is associated with a 26% -50% increased risk in mortality.18 , 20 These situations have been shown to predict worse disease outcomes and quality of life in older populations.21 , 22

It is a fact that the world has to live with the new coronavirus. Therefore, in the ongoing COVID-19 pandemic, it is a necessity to examine social isolation, loneliness and quality of life in elderly people who are confined at home and isolated from social life. In this process, it is clear that understanding the social isolation, loneliness, and factors affecting the quality of life that the elderly are exposed to will actually facilitate the rehabilitation of elderly people. However, the effects of COVID-19 quarantine on the health of older adults have not yet been adequately studied. This scoping review gathers all available evidence on this topic and makes it possible to identify gaps in the literature for new primary studies. The aim is to evaluate the social isolation, loneliness and quality of life of elderly individuals during the COVID-19 pandemic and to map suggestions to reveal and improve the current situation.

Methods

We believe scoping review is most appropriate to present the current assessment and possible recommendations of the wide variety of study contents mentioned above. A scoping review allows a broader search and answers multiple questions while still performing a systematic search.23 The conduct of this scoping review was based on the framework and principles reported by Arksey and O'Malley24 and further recommendations provided by Levac, et al.25 For scoping reviews, the PRISMA-ScR extension was developed to improve the quality and conduct of reporting of scoping reviews.26 Appropriate adjustments were made to reflect the nature of the evidence examined, and the review included the following 5 main steps.24

Stage 1: Identifying the research question

Stage 2: Identifying relevant studies

Stage 3: Study selection

Stage 4: Charting the data

Stage 5: Collating, summarising and reporting the results

The optional ‘consultation exercise’ recommended by Arskey and O'Malley24 was not conducted.

Data sources and search strategy

A detailed summary of the literature search is provided in Fig. 1 . First of all, on Google Scholar, to get an overview of the relevant literature, the discovery includes free text terms such as "elderly", "COVID 19", "quality of life", "social isolation", "loneliness" and "quarantine" a purposeful research was carried out. Later, a search strategy was developed to explore the current situation and assessments for quality of life assessment in the elderly during the COVID-19 pandemic process.

Results

Literature search

The results are presented in a PRISMA-ScR diagram flow (Fig. 1). In the first evaluation, 1193 articles were obtained within the scope of the research. After scanning all article titles for eligibility and eliminating duplicates in databases, the title and summary of the remaining articles were read. Since they did not meet the inclusion criteria, 1139 articles were initially excluded from the study. Fifty-four articles suitable for full reading were obtained. Finally, based on the inclusion criteria, a total of seven studies were included in this scoping review focusing on isolation, loneliness and quality of life in the elderly during the pandemic process, with the consensus of two researchers. These studies are three descriptive and cross-sectional studies, a quasi-experimental study, a pre-post pilot program, an editorial note and a correspondence (Table 2).

Characteristics of included articles

In an article by Armitage and Nellums (2020) (correspondence), the results of isolating older adults during the COVID-19 outbreak are discussed. At the same time, it is emphasized that social isolation among elderly adults is a “serious public health problem”, increasing the risk of cardiovascular, autoimmune, neurocognitive and mental health problems. It is stated that social isolation will disproportionately affect elderly individuals, especially those whose only social contact is outside the home, and that older adults who have no close relatives or friends are more alone, isolated or out of sight, and are at great risk.13

In an editorial note, it is stated that social service experts serving the groups most defenseless against COVID-19 have developed creative practices to support efforts to keep them in contact with others in order to alleviate loneliness and social isolation in the elderly. In this process, face to face activities and contacts have started to be facilitated virtually by means of individual devices and video conferencing. Also, social distancing, personal protective equipment and virtual reality devices are introduced. The security of daily telephone calls, home delivery services, health visits either virtually or by telephone, health education and news sharing have become a part of social services. As a result, this study emphasizes that social service practices have brought about striking and rapid positive changes for older adults.27

In a study conducted by Bidzan-Bluma et al, the writers examine predictors of quality of life, comfort and satisfaction with life in older adults in Germany and Poland during the pandemic, such as risky behavior, trait anxiety, a feeling of threat, sleep quality and optimism, and compare them between three different age groups. Research of quality of life in the pandemic in the >60 age group gave conflicting results. It was found that the older people assessed their quality of life, comfort, satisfaction with life and sleep quality higher than did the younger groups with whom they were compared.28

The Keck Medical Faculty arranged a pilot scheme to combat loneliness and isolation in older adults living in California. A total of 115 postgraduate students from different professional fields made contact with the older adults. Students engaged phone calls with older adults 2 to 5 times per week for 6 weeks. On a web page prepared for the benefit of the students, there were articles on age awareness and communication strategies, age abuse knowledge pages, age abuse websites, consumer protection resources, personal care resources (empathy, stress management, COVID-19) and peer evaluation articles. Also, information was added on food help programs, healthy habits, financial assistance programs, family and caregiver support, COVID-19 resources, technical help and coping skills. A weekly news bulletin was sent to the students containing inspirational tips and stories. In this study, students completed Qualtrics surveys containing 18 questions before and 6 weeks after being matched with an older adult. The research questions were about the interests of the students in participating in the program, whether there was a perceived benefit for the students participating in the program, and what were the students' perceptions about the support system of older adults. The preliminary results of this study show statistically significant changes in the reported benefits and outcomes. It shows that such programs can reduce the social isolation and loneliness of older adults and students with stay-at-home restrictions.29

Stolz et al. examined the effect of measures to restrict COVID-19 on loneliness in older adults in Austria. In this study, three different analyzes were made and pre-pandemic and pandemic loneliness levels were evaluated with the UCLA-3 scale. In this study, it was found that the loneliness levels of older adults increased in 2020 compared to previous years, they were affected by loneliness, there was a correlation between the restriction measures announced and loneliness, and loneliness rates were higher, especially in those living alone.30

In the study by Zurigat and Fattah, the authors investigated the effect of the Quran reading voice on the quality of life of older adults. Because of the quarantine, the quality of life questionnaire was applied by means of Google Form. The experimental group listened to the Quran for ten minutes three times a day for 30 days; the quality of life of the experimental and control groups was measured, and it was concluded that there was an effect on the quality of life.31

In the study by Macdonald and Hülür, how the COVID-19 epidemic affected the well-being and loneliness of older adults and the structural and functional characteristics of social relationships. The study was conducted using data from 99 older adults who participated in (a) a 3-week micro-longitudinal study on social relationships and well-being in 2019 and (b) a weekly online survey for 4 weeks of COVID-19 lockout. The main conclusions are that the global pandemic has had a significant negative impact on the emotional well-being and loneliness of older adults, and aspects of social relationships are associated with loneliness both before and during the pandemic.32

Recommendations of the reviewed studies

The effects of social isolation and loneliness in the elderly during the COVID-19 pandemic and the literature recommendations for improving quality of life are summarized in Table 3 . It is emphasized that during the pandemic, older adults in the worldwide, and especially those whose only social contact is outside the home such as in daycare venues, community centers and places of worship will be disproportionately affected. It is emphasized that social support networks and online technologies can be used to reduce the negative effects of the pandemic process. It is recommended that elderly people talk more frequently with people who are important to them, close family and friends, volunteer organizations or healthcare professionals on the phone, or social assistance projects that provide peer support during the isolation period. In addition to this, it is argued that cognitive behavioral therapy can be used to reduce loneliness and improve mental health.13

Author Aim Main recommendations
Armitage & Nellums, 202013 Emphasizing COVID-19 and the consequences of isolating the elderly On this topic, more use of online technologies in social support networks is proposed.
Among them are community outreach projects that provide peer support during more frequent phone calls or compulsory isolation with other people from close family and friends, volunteer organizations or health professionals. It was also highlighted that cognitive behavioral therapies can be used online to reduce loneliness and improve mental health.
Berg Weger
&Morley, 202027 		Presenting implications for gerontological social work in the process of loneliness and social isolation in older adults during the COVID-19 pandemic. In this regard, the importance of easy and fast tools to evaluate loneliness and social isolation was emphasized. It is recommended to develop and adapt evidence-based interventions to address loneliness and social isolation. Innovative methods (eg virtual / tele-health delivery methods) and intervention components (eg laughter, mindfulness, meditation, recall and gardening therapy, body movement (eg exercise, dance, yoga) are recommended in this process.
Bidzan-Bluma et al, 202028 In the study, they studied the predictors of quality of life, well-being, and life satisfaction (including risky behavior, trait anxiety, feeling of threat, sleep quality, and optimism) during the pandemic in older people from Germany and Poland and compared them to three different age groups. It was emphasized that despite the better psychological functioning of older adults compared to young adults during the pandemic, various types of assistance, including stress reduction, should be implemented to improve the psychological resources that promote quality of life in the elderly. Methods that focus on the body, such as breath meditation and Autogenic Training, and methods based on cognitive behavioral therapy were suggested.
Joosten-Hagye et al, 202029 California, the Keck School of Medicine collaborated with A program was created by linking 115 interprofessional graduate students with older adults. In conjunction with this program implemented in this study, the next basic steps to develop future programs, it is suggested to include older adult demographics (expectations, attitudes, perceived benefits, etc.). It is emphasized that the inclusion of loneliness and isolation reports from such students and older adults will provide a stronger evidence base for similar programs.
Stolz et al, 202130 Evaluating the impact of COVID-19 containment measures on loneliness among older adults in Austria. However, it was noted that the effects of social isolation and loneliness on the elderly are short-lived, and therefore strong negative consequences are not expected for the mental health of older adults. However, the effects on loneliness and subsequent mental health problems are said to be both longer lasting and severe if future restraint measures are implemented repeatedly and / or over longer periods.
Zurigat & Fattah, 202031 The study aimed to investigate the effect of the holy Quran voice on the quality of life among the elderly during Coronavirus (COVID-19) Outbreak The results of the study have shown that the level of quality of life came with a lower degree in the pre-measurement of the two groups, as well as the mental health domains that were the most affected in a positive way through listening to the Quran, additionally, there were statistically significant differences between the post-measurement of the two groups and favor of the experimental group. The researchers recommend that the regularity strategy should be used to hearing the Quran because of its positive effects on the various body systems.
Macdonald & Hülür, 2021 32 How the COVID-19 epidemic affected the well-being and loneliness of older adults and the role of structural and functional features of social relationships were examined. Its key findings suggest that the pandemic has significant negative effects on the emotional well-being and loneliness of older adults. However, it is stated that maintaining social communication to a satisfactory level during this period reduces this effect. Therefore, it is emphasized that enabling older adults to stay in touch with their social environment according to their personal preferences can reduce the impact of any lockdown on their well-being in the future.

It is emphasized that older adults can use various strategies to combat the crisis during the pandemic. First of all, it is important for there to be an easy and quick means of evaluating loneliness and social isolation and evaluating whether an old person is alone or isolated with his or her social group. There are a number of instruments which may be used, but the ALONE scale has been developed and is recommended. After that, it is argued that evidence-based interventions can be developed and implemented in order to limit loneliness and social isolation, and that social service specialists can move beyond traditional support approaches by using innovative methods such as virtual or tele-health presentation methods and intervention components such as laughter, mindfulness, meditation, recall and gardening therapy, or body movement such as exercise, dance or yoga. In addition, it is stated that learning new skills, and learning the importance of technology and the importance of being prepared for different situations and how to establish relations with people in non-traditional ways can be a part of social service practices. It is recommended that social service experts, in adopting technology as a service provision option which can be applied, can provide it in a similar way to traditional interventions. Also, it is noticeable that COVID-19 triggers more age discrimination in society.27

In the findings obtained from one study which was examined, it was recommended that while older adults had better psychological functioning than young adults during the pandemic28, they could use breath meditation, autogenetic training and cognitive behavioral therapy methods to improve the psychological resources which support the quality of life.13 , 28 It is emphasized in a study in which a program was conducted which supported the development of social relations between older adults and postgraduate students from various postgraduate programs that social isolation and loneliness can be reduced in socially isolated older adults. At the same time, it is said that it is important to include the demography of older adults such as data on expectations, attitudes and perceived advantages in order to develop this kind of program in the future.29

Stolz et al. reported that COVID-19 restrictions in Austria gave rise to increasing loneliness among older adults, but these effects were a short term, and therefore strongly negative results were not expected for their mental health. Against this, it is recommended that the effects of restrictions on longer or repeated social isolation in the future should be monitored closely.30 In the study of Zurigat and Fattah (2020), unlike the above suggestions, the authors recommend listening to Quran readings due to its positive effects on various bodily systems.31 Finally, Macdonald and Hülür recommended that social communication should be maintained to a satisfactory level in this process and that older adults should be kept in touch with their social environment according to their preferences.32

In this review, a flowchart was created after evaluation of the studies, containing the main study recommendations. The authors generally emphasize the flowchart below to reduce loneliness and improve the quality of life of older adults isolated during the COVID-19 pandemic (Fig. 2 ).

Discussion

As to 4 March 2021, there have been 114.653.749 confirmed cases of COVID-19, including 2.550.500 deaths, reported to World Health Organization, from more than 223 countries and territories.33 COVID-19 has changed the normal way of living in the worldwide, and has had an unparalleled devastating effect on older adults in particular. This scoping review provides important information on improving the quality of life of older adults whose loneliness has increased with social restrictions during the COVID-19 pandemic.

Evaluation of loneliness and social isolation in older adults during the COVID-19 pandemic

Loneliness is a big problem in the coronavirus pandemic, especially for older adults. However, although it has been predicted that older adults would be at particularly high risk of the adverse psychological effects of COVID-1934, emerging data show the opposite.15 , 28 , 35 Considering that this situation is still continuing and is likely to continue for some time, it is necessary to take urgent action. For this, there is a need for means to evaluate social isolation, loneliness and quality of life especially in older adults, and particularly those living alone, who are at greater risk.30 In this regard, the ALONE scale, which evaluates loneliness quickly and easily, has been developed and is recommended.27 Also, the revised UCLA Loneliness Scale is another scale which can be used as a standard scale to measure perceived loneliness.36 The shortened version of this scale, the Three-Item UCLA Loneliness Scale, is widely used to identify lonely older adults.37 In conclusion, it is thought that it will be a guide in managing the process of seeing the current situation with scales providing objective data.

Making greater use of the opportunities of technology in the COVID-19 pandemic

It is important to make greater use of the opportunities of technology in order to reduce the effect of isolation in older adults relating to the restrictions.13 , 27 Even before the pandemic, there was a steady increase in the number of older adults interested in technology with 75% of those over the age of 65 going online every day, and an increase of 24% between 2013 and 2017 in the number of adults over the age of 65 possessing a smartphone.38 At the same time, it has been stated that there may be inequalities in access to digital sources or in literacy.13 In particular, the precondition to benefit from remote intervention is to have access to the necessary technology. However, certain technologies may not be accessible due to geographic location (eg rural residents) or socioeconomic status.39 Also, it has been emphasized that reliance on technological solutions puts a greater burden on those without access to technology, such as older adults who are socially disadvantaged or those who are cognitively or sensorily impaired.40 A qualitative study was conducted with the aim of determining older adult's first experiences of household isolation, social distancing and shielding in the pandemic, and the plans they made in the COVID-19 pandemic. It was concluded that people over 70 adapted to household isolation, social distancing and shielding by using social media and neighborhood resources.41 Differently however, it is reported in the literature that the evidence for the effect of video to reduce loneliness in older adults is very indeterminate.42 In conclusion, it is thought that while the effects of the pandemic last, use of the various mostly free means of video communication such as Facebook, Whatsapp, Telegram, Google, Twitter and Skype by older adults under lockdown will be of benefit. It is also thought that methods such as daily telephone calls will help older adults who have limited access to technology to remain socially active.

The use of cognitive behavioral therapy during the COVID-19 pandemic

Chronically ill older adults are a defenseless population with lower quality of life in this COVID-19 crisis.43 For this reason, it is important to provide online cognitive behavioral therapy online to reduce the loneliness of older adults during the pandemic and to improve mental health and thus the quality of life.13 , 28 Also, innovative methods such as virtual or tele-health presentation types, various intervention components such as laughter, mindfulness, meditation, recall and gardening therapy and bodily movements such as exercise, dance and yoga are recommended by social service experts.27 It is thought that making older adults feel they have a place in social life and reaching them by different methods will help to reawaken the feelings of self-esteem or self-respect which they have forgotten as a result of the COVID-19 pandemic measures.

The use of various individual intervention components during the COVID-19 pandemic

Various individual interventions are having more frequent telephone conversations with important people, close family and friends, peers, volunteer organizations or health professionals, and social assistance projects contributing to this process.13 Also, it is reported that they can benefit from pilot applications which are created by matching old and young people.29 Similarly, older adults experience lower levels of loneliness if they have a larger social network, have more social interactions before and during the pandemic, did not live alone, and report that social support was avaible to them.32 In addition, it is emphasized that interventions relating to older adult's religious beliefs are also important.31 Additionally, a study with elderly patients during the COVID-19 outbreak found that optimism, social support, and health-related quality of life were positively correlated. It is emphasized that optimism and social support can be effective in coping with difficulties and buffering depression, thus positively affecting the quality of life.44 In conclusion, it is thought that positive results may be obtained with guidance and interventions to meet the needs of older adults with regard to the characteristics of their culture, value and beliefs.

Conclusions

The findings show that older adults experience social isolation in connection with the restrictions during the pandemic, and that their degree of loneliness and quality of life are negatively affected. Older adults who are staying outside the home in social service institutions, those who are living alone, and those who have a low socioeconomic level are at particularly greater risk. For this reason, it is important to rapidly evaluate the social isolation, loneliness and quality of life of older adults in this situation, to create awareness on this topic, and to carry out the necessary measures at a national and international level.
