Introduction

Improvements in the treatment and management of cancer have led to an increase in life years in patients with advanced cancer.1 2 As all patients could not be cured, several patients with advanced cancer are surviving with cancer. To manage their cancer-related symptoms and strive their daily lives, hospitalisation is frequently needed; even though that is an unwanted experience for them.3 Patients with advanced-stage cancer have a desire to live at home to accept the inevitable, and to prepare for their death.4 However, compared with the enormous interest and investment in cancer treatment, there is relatively insufficient interest and investment in care for the lives of patients with advanced cancer at home.

A literature review on the supportive care needs of patients with cancer suggests that supportive treatments, including the provision of information and spiritual support, are necessary.5 This is particularly relevant for elderly patients with cancer, who also require the need for extended support networks beyond immediate family members and assistance with financial issues. To enable patients to stay at home until the end of life, various factors come into play, including patient preferences, home healthcare provision, social support networks, diverse healthcare policies and the advancement of palliative care.6 In addition to various information and spiritual support, patients with advanced cancer may require daily medical care, and if there is restricted access to the necessary care and medical services, they may also need frequent hospitalisations and readmissions against their wishes.7 8 To facilitate their stay at home, appropriate services are crucial, such as home-based supportive care (HbSC) programmes. HbSC involves medical staff visiting patients to provide medical service, allowing patients to live in their preferred homes. Patients receiving palliative care expressed satisfaction with the medical interventions provided through HbSC.9 Through a systematic review, Higginson and Sen-Gupta verified that home care was the favoured choice among patients with advanced cancer.10 Therefore, to meet patient preferences and elevate their quality of life (QoL), HbSC for patients with advanced cancer is a valuable endeavour.

Healthcare systems have been moving towards a value-based healthcare system that emphasises value over volume of services in recent years.11 Value could be defined as outcomes achieved considering the individual patient rather than volume of services delivered by healthcare providers.12 In this aspect, the value of HbSC can be measured by the improvement in the QoL of patients with advanced cancer receiving HbSC. However, the effect of HbSC on patients’ QoL has not been thoroughly investigated before. A systematic review in 1998 concluded that the effectiveness of comprehensive home care programmes is still ambiguous, with only two out of five randomised studies noting positive effects on the physical aspects of patients’ QoL.13 In a systematic review from 2016, the level of QoL varied depending on the patient group included in this study, and a lack of controlled clinical trials for HbSC targeting patients with advanced cancer was highlighted.14 Nevertheless, there has been no investigation on studies after 2016, and no research on the impact of the provided programmes on QoL. Therefore, a comprehensive and systematic review is needed on the effects of HbSC intervention programmes on the QoL of patients with advanced cancer. This study performed a systematic review to assess the impact of HbSC programmes on the QoL in patients with advanced cancer.

Materials and methodsSearch strategy and selection methods

The review question was as follows: ‘Do supportive home care programmes for patients with advanced cancer improve their QoL and reduce unplanned hospital visits?’ The protocol of this systematic review was registered in PROSPERO (CRD42022341237). We searched articles from PubMed, Embase, Cochrane database, CINAHL and Web of Science, published from 1 January 1990 to 30 May 2023. The search strategy was developed with an experienced librarian as table 1, box 1.

PICOs for the systematic review

We investigated trial studies of home-based programmes. Trial studies included the management of medical, physical and psychological symptoms. We did not include individual components of palliative care, such as advanced care planning. The results of each search were downloaded into a reference management software program to identify duplicate articles and further review. Two authors (D-WL and IYH) screened the records and selected articles according to the predefined inclusion and exclusion criteria. The inclusion criteria were as follows: (1) a clinical trial study; (2) a study on patients with advanced cancer (incurable and/or palliative stage); (3) an intervention programme must be an HbSC programme; and (4) QoL must be reported as an outcome variable. The exclusion criteria were as follows: (1) presented outcomes in irrelevant forms; (2) not able to extract the size of the association; (3) letter, commentary, or review articles; (4) the study used an identical study population to other included study; (5) articles not written in English; and (6) non-human studies. If the two authors disagreed about the eligibility of a study, the authors agreed after discussion and deriving a mutual understanding with a third author (BC).

Data extraction

We extracted the following data from all articles using a data-extraction sheet: first author, year of publication, country, study design, number of participants, aim of the study, inclusion criteria for participants, percentage of primary cancer site of participants, exclusion criteria for participants, intervention programmes, details of the intervention programme, components of the intervention programme (home visiting, education, training, nursing, counselling, clinic visiting, tele healthcare, team meeting, period/number of visits, total programme duration), team members and their roles, provided programme for the control group, outcome measurement methods for QoL, timing of the outcome measurement, and QoL-related results including main results, effects measurement, effect size (point estimate, difference, standard deviation [SD], and 95% confidence interval).

Quality assessment

The quality assessment of each article was conducted according to the Methodology Checklist of Scottish Intercollegiate Guidelines Network (SIGN).15 After the assessment of the internal validity, the overall assessment was checked using three options: those designated as ++ (high quality; all or most of all standards are met. The results of the study will not be changed by the unmet standards); + (acceptable; some of the standards are met. It is assumed that the results will not be changed by the unmet standards); – (low quality; all or most of all standards are not met. It is assumed that the results of the study could be changed by the unmet standards).

ResultsSearch results

Figure 1 shows the process of selecting relevant studies for the systematic review. We screened 9078 records and removed 3802 duplicated records. Next, we excluded 4824 articles based on the title among 5,276 records screened. We assessed abstracts of 452 articles and excluded 337 irrelevant studies. Full texts of 115 studies were examined, and 98 studies were excluded. We manually checked the reference lists of the assessed full texts. Finally, 17 studies were included for the systematic review. Table 2 shows the results of the SIGN checklist for the included studies. We scored 4 studies as high-quality studies, 11 as acceptable studies and 2 as low-quality studies.

Description of included studies

Study characteristics

The types of interventions were diverse, including not only simple symptom management but also emotional support, multidisciplinary team-based patient care, rehabilitation and exercise, among others. Nordly et al,18 Kleijin et al,19 Lehto et al 17 and Xiao et al 20 examined the impact of psychological support on patients’ QoL and symptoms. Steel et al 21 investigated the effects of multidisciplinary management on QoL, depression, pain, fatigue and other factors. Uitdehaag et al,22 Molassiotis et al,23 and De Wit et al 24 assessed the effectiveness of nurse-led symptom control, while Study Hermann et al 25 examined the impact of standard education for doctor. Cheville et al,16 Edbrooke et al 26 and Cheville et al 27 evaluated the effects of rehabilitation and exercise interventions, with Cheville et al 16 specifically focusing on the effects of telerehabilitation. Ammari et al, 28 Pilegaard et al 29and Northouse et al 30 provided interventions in the form of counselling and information for patients and their caregivers. In Mills et al 31 ’s study, patients periodically measured their own QoL.

Cancer types

Most of the studies did not have restrictions on the type of cancer under investigation, while some studies specifically targeted certain cancer types. Edbrooke et al,26 Lehto et al 17 and Mills et al 31 focused on patients with lung cancer, and Steel et al 21 ’s study included patients with primary or secondary liver cancer. Cheville et al 27 and Molassiotis et al 23 conducted research on lung cancer (51.6%) and colorectal cancer (48.4%) or colorectal cancer (67.1%) and breast cancer (32.9%).

Inclusion criteria

Most studies targeted adults aged 18 or 21 years and older. However, in the three studies, there was no clear age criterion.22 24 27 The expected life expectancy varied, with some studies having a minimum of 3 months,19 24 others requiring at least 6 months,16 ,23 ,26 ,30 and some falling within the range of 2–9 months.32 Depending on the study, participants were either in a palliative or hospice care setting19 20 25 28 or in an earlier stage.17 21 22 27 29–31 The studies targeted patients with preserved functionality, characterised by ECOG PS ≤2,26 WHO PS 1-2,29 Karnofsky functional status score ≥80,17 Activity Measure for Post-acute Care (AM-PAC) basic mobility score ranging from 53 to 66,16 or Ambulatory Post-Acute Care Computer Adaptive Test scores between 50 and 75.27

Characteristics of intervention

Table 4 shows the characteristics of home care programmes across the studies. We classified the characteristics of the interventions. Interventions across studies included home visit (n=12), education (n=13), nursing (n=6), psychological consultation (n=6), clinic visit (n=4), check-up via phone (n=11) and multidisciplinary team meeting (n=7). Many studies provided home visit and education, but the studies reported after 2010 additionally included psychological intervention, exercise or rehabilitation programmes.

Table 4

Intervention characteristics in studies of home care programmes for patients with advanced cancer

Interventions were provided by various healthcare professions: nurse, doctor, dietitian, health-technician, coordinator, social workers, physiotherapist, nutritionist, priest, psychologist and physical therapist. Most of the studies were driven by nurses; further, interventions were provided in addition to services other than nursing services. The most frequent home care service was provided through a home visit,18–20 22–26 28–31 and some services checking the status of patients via phone.16 17 20–24 26 27 29 30 There was a type of intervention in which the QoL of the patient was continuously written in a diary and only reported to the medical staff.31 The total programme duration ranged from 3 weeks29 up to 13 months,22 and the number of visits varied across the studies.

Uitdehaag et al reported the results of home-based nurse-led follow-up for patients with advanced cancer, an experienced specialist nurse visited the patient’s home once a month to conduct repeated assessments of the patient’s symptoms and issues.22 Regular communication occurred with the attending physician and the patient’s general practitioner. When necessary, patients had the option to contact the nurse by phone. Palliativmedizinische Initiative Nordbaden (PAMINO) is a multidisciplinary educational programme based on the curriculum of the German Medical Association (Bundesärztekammer) and the Association for Palliative Medicine, and the results was reported by Mills et al. 25 It covers topics such as pain psychology, legal aspects, clear communication with patients, ethics and attitudes, pain management, symptom control, specialised pain therapy, end-of-life care requirements, physician communication, burnout, palliative care in geriatrics and long-term care. Northouse et al reported the effects of home-based informative and supportive programme in 2012, a home-based dyadic intervention that provides information and support to patients with cancer and caregivers through nurses with home visits and contact via phone.30 Molassiotis et al reported that home care nursing programme is a multimodal programme and includes symptom assessment, patient education, and/or treatment of symptoms based on the agreed protocols.23 Home visits occur during the first week of the programme, and subsequent home visits or monitoring phone calls are performed per week during all cycles by a nurse. When multiple toxicities occurred, the home care nurses assessed patients further, asking whether they could be managed at home or required additional medical support, such as earlier consultations with their clinicians or emergency departments or cancer centres, and facilitated these visits. In the study of De Wit about the pain education programme, patients were called at home at 3 and 7 days postdischarge to determine whether the pain information was sufficient, and district nurses received patients’ pain complaints from the hospital and visited their homes.24 Mills et al tested the effects of recording QoL data. During the regular recording of QoL data intervention, patients completed their QoL diary at home regularly each week to share the information with any health professional involved in their care for 16 weeks.31 Jordhøy et al provided the programme by the palliative medicine unit (PMU), follow-up consultations by the GP and the community nurse at home.32 The PMU consultant team comprised the GP, the community nurse and a consultant nurse or physician from the PMU. With the patient and the informal caregiver, individual treatment plans were set up, and GP and the community nurse follow-up consultations at home were arranged according to patients’ needs and predefined minimum standards. The PMU also participated in the inpatient care. Pilegaard et al conducted that the cancer home-life intervention is a tailored, occupational therapy-based, and adaptive programme by occupational therapists.29 They participated in three home visits during the study period. This programme enabled patients to perform and participate in everyday activities at home that they prioritise but face difficulties performing.

Cheville et al reported in 2013 that the Home-Based Exercise Programme with a 90-min instructional sessions and a pedometer-based walking programme comprising two sets of five-exercise routines.27 At 1, 3, 5 and 7 weeks from the baseline, patients contact the physical trainers who had provided their initial instruction via calls for a short interview to screen for concerning signs or symptoms. In 2019, Chevillie et al reported telerehabilitation that home-based exercise programme, with or without pharmacological pain management.16 It involved the implementation of an individualised fitness programme delivered by physical therapist fitness care managers through telephone communication, and in some cases, nurse pain care manager-directed pharmacological pain management. Contrastingly, the control group underwent automated monitoring at intervals of 2 weeks or 1 month to assess pain and function. The experimental group, on the other hand, evaluated pain and function at baseline, 3 months, and 6 months through telephone interviews. Edbrooke et al also reported other home-based exercise programme.26 In the home-based rehabilitation programme, participants received an initial home visit, followed by weekly phone calls to review their exercise programme and receive symptom management support. The exercise programme consisted of aerobic exercise at least twice a week and resistance training for the lower limbs. To standardise the programme, the physical therapist scripted the content of each exercise session, including various aspects of the exercises. Similarly, the nurse scripted sessions during phone calls to address symptom management and the current management strategies. Assessments were conducted at baseline, 9 weeks and 6 months.

Nordly et al reported that the existential–phenomenological therapy combines specialised palliative care with psychological intervention, promoting QoL and relieving physical, mental, social and spiritual suffering.18 Patients and informal caregivers had two sessions with a psychologist within the first month, followed by needs-based interventions. The FamCope intervention study reported by Ammari et al, provided consulting services to cope with problems and needs of patients with advanced cancer.28 Families in the experimental arm received six home visits in a 3-week interval, in addition to usual care. Kleijin et al investigated the effects of the Life-Review Therapy and Memory Specificity Training, comprising an approximately 1-hour interview programme with 4 weekly sessions on a particular lifetime period (childhood, adolescence, adulthood and whole life span) conducted with a psychologist.19 Steel et al investigated the collaborative care intervention providing a psychoeducational website with self-management strategies, bulletin board and other resources to participants.21 Additionally, participants had face-to-face meetings with a care coordinator during physician appointments every 2 months, and telephone follow-up sessions occurred every 2 weeks. The assessment of the intervention’s effectiveness was conducted at baseline and after 6 months. Letho et al reported the effects of mindfulness-based therapies consisting of trained nurses visiting patients at their homes and conducting 45-min sessions, which included gentle yoga training, practices to expand awareness and relevant discussions. This intervention lasted for 6 weeks.17 The psychological support programme comprises three sessions to review patients’ lives and formulating a life-review booklet with Erikson’s theory and Confucian thoughts.20

Outcomes related to QoL

Table 5 shows the effect of home care programmes on patients’ QoL. QoL tools used in the studies included the following: Euro QoL-5 Dimension, 36-Item Short Form Survey European Organisation for Research and Treatment of Cancer (EORTC) QoL Questionnaire, Core 30 (EORTC QLQ-C30); a shortened version of the EORTC QLQ-C30 (EORTC QLQ-C15-PAL); Functional Assessment of Cancer Therapy—General (FACT-G) and Functional Assessment of Cancer Therapy—Lung (FACT-L); Hospital Anxiety and Depression Scale (HADS). Nine studies reported that interventions improved QoL.21 ,16–18 20 23 26 27 30 A study shows that psychological interventions improved social functioning (−12.7±5.1, p = 0.014), global QoL (−8.2±4.0, p=0.04) and emotional functioning (−9.1±3.5, p=0.007) of EROTC QLQ-C30 after 6 months.18 Another study shows the psychological support effects of the programme on overall QoL of patients with advanced cancer; between-group (p<0.001) and interaction effects (p<0.001) were significant.20 In another study of the home-based informative and supportive programme, the social domain of patients’ QoL was significantly different (p=0.002) between the intervention and control groups, measured by the interaction term in Multivariate Analysis of Covariance for the repeated measured data.30 Mean changes and SD of FACT-G subscale between the home-based exercise intervention and control groups in mobility (4.88±4.66 vs 0.23±5.22, p=0.002), fatigue (4.46±8.65 vs −0.79±9.11, p=0.03), and sleep quality (1.46±1.88 vs −0.11±1.71, p=0.002).27 Collaborative care intervention showed the improvement among patients with advanced cancer in overall QoL from baseline to 6 months follow-up.21 Patients with home care nursing programmes showed improved financial problem and decreased anxiety, compared to before its implementation.23 However, some interventions reduced QoL. In cases in which patients with lung cancer who could not operate were regularly recorded for QoL, and there was no provision of appropriate information, mean differences of FACT-L, FACT-G and Palliative Care QoL Index (PQLI) changes in score from 0 to 4 months between the intervention and control groups were −10.4 (p=0.04),–8.7 (p=0.04) and 0 (p=0.93), respectively.31

Results of home care programmes on QoL for patients with advanced cancer

Discussion

Our review shows that the effectiveness of HbSC programmes, when compared with standard care for patients with advanced cancer, has positive effects on measurable and value-related outcomes like QoL. Seventeen studies investigated the effects of home care programmes on the QoL of patients with advanced cancer. Nine studies show the positive effects on QoL, including social functioning, emotional functioning and subjective QoL.16–18 20 23 26 27 30 However, inconsistent results were found according to the components of interventions. Owing to the diversity of the intervention and study population, studies failed to show a consistent pattern. Nevertheless, programmes such as team meetings, periodic management (home visits or check-up via phone), and nursing and psychological support affected the positive outcomes.

Home-based programmes can improve specific domains of the life of patients with advanced cancer. The domains of QoL associated with the intervention can differ by the specialised programme of home-based care. Home-based nursing care can improve financial difficulties and mood status.23 Providing information and supporting patients can empower patients’ social functioning,30 although the results were inconsistent across the studies.28 Psychological programmes can improve social and emotional functioning and the overall QoL of patients with advanced cancer.18 20 Further, exercise programmes can improve patients’ mobility, fatigue and sleep quality.27 Although the overall QoL rating was not related with the intervention programme as cancer progresses, various domains of life can be supported by home-based programmes. Further, this study implies that home-based care should comprise diverse programmes with multidisciplinary components, which target the individual specific domains of life.

This study showed that HbSC programmes improve patient’s QoL in some domains, but the analysis was limited owing to the variability of the sample included. Each study included patients with various cancer types and settings. Some included patients with an adjuvant setting, some included patients with incurable states, and some studies targeted patients with terminal conditions. Although most studies have yet to present or insufficiently mention information on care timing, among the studies that suggested survival information, the psychological programme improved social and emotional functioning in a study with a 6-month survival of 60%.18 Further, studies with a 12-month survival rate of 60% or more showed improvement in mobility, fatigue and sleep quality.27 Moreover, there was no difference in QoL in other studies with a 24-week survival rate of 70%, and no difference in QoL was identified in studies with a median overall survival of 2 months in the programme group.33 Palliative care is appropriate for patients with any stage of cancer, and the benefits of early palliative care on QoL improvements are well known.34–36 Although some studies in our analysis have confirmed the advantage of early palliative care, more RCTs for HbSC are necessary to prove this. However, the effectiveness of palliative care could be more mitigated in people with mild symptoms, good QoL and good performance, but this could not be confirmed owing to insufficient information in the analysed studies. A more controlled clinical trial is needed to find a subgroup benefiting more from palliative care.

This systematic review did not yield the quantitative size of the association between HbSC programme and QoL. However, the authors reviewed the literature and came to the following conclusions. Interventions provided in HbSC programme should be based on a multidisciplinary team and include the monitoring and management of pain and side effects of cancer treatment, and provide psychological support. Periodic home visits by medical staffs and direct online consultation systems are needed, whereby long-term low-intensity visits by non-professional medical staff seems ineffective. Finally, caregivers who care for the patients must also be the targets of HbSC programmes.

HbSC was studied in Denmark, the USA and the UK. As studies included in the systematic review focused on the effects of HbSC, there was no description or suggestion on policies or healthcare systems. According to the literature, these countries have supported HbSC. The Danish healthcare system is universal and based on the principles of free and equal access to healthcare.37 Denmark has a comprehensive home-based primary care system, from preventive services to rehabilitation services, cooperating with resources in the community.38 Home-visiting nursing services based on a doctor’s prescription are provided by the local government free of charge in Denmark.39 The primary healthcare team composed of GPs and community nurses is also involved in the palliative pathway when the terminally ill patient stays at home.40 The USA, which does not have a public health insurance system that covers all citizens, provides home healthcare through the Medicare system, a public health insurance system for the elderly and the disabled.41 This programme includes the management and evaluation of treatment plans, education and training of patients and caregivers, and management of drugs, including injection, tube replacement and rehabilitation. These services are provided under a contract with a doctor.42 The UK National Healthcare Service provides healthcare services by taxation under the responsibility and authority of the central government. In the UK, home nursing can be provided instead of the typical care given at hospitals or nursing homes for patients with terminal illnesses.43 Countries where more than three included studies were reported regarded HbSC as a public domain and supported HbSC by the government.

In general, considering the complex problems faced by patients with advanced cancer, palliative care is recommended to be provided by an integrative team of physicians, nurses, social workers, chaplains and pharmacists. Moreover, HbSC could produce better outcomes when performed by a multidisciplinary team. Care providers should offer a holistic evaluation and a detailed and tailored plan for each patient for high-quality palliative care for patients and caregivers through home care. This plan should include medical care, nutritional support, psychosocial care, pastoral care, management for caregivers and end-of-life care. Further, as physical activity can improve the QoL and relieve symptoms even in patients with advanced cancer, home care could be more effective by including individualised exercise therapy in the home care programme. HbSC also should provide strengthened control and management for medical needs for cancer-related symptoms including pain, physical activity for patients with advanced cancer, and psychological needs while staying at home or by predicting the place of care by anticipating the course of a patient’s disease. If symptom control is insufficient at home, patients with cancer tend to stay or die at a medical institution rather than at home.44 45 Early identification of proper patients and intervention are challenging but essential for patients to benefit sufficiently. For timely palliative care, regular screening of HbSC needs among inpatients and outpatients and establishing criteria for selecting patients are necessary. Additionally, as patient status and condition continuously change, periodic multidisciplinary evaluation and coordination of plans are crucial.

Moreover, most studies conducted the patient assessment and care through home visits, outpatient clinics and telephones. Recently, there have been attempts to expand access to palliative care through telemedicine despite barriers such as technical problems46 and participants’ digital literacy.47 Although there are some restrictions, telemedicine is expected to be settled in the medical field soon. Accordingly, it is assumed that telemedicine can be actively used in HbSC. Further, the adoption of digital health technologies, such as wearable devices and mobile healthcare programmes, will provide advantages such as anxiety relief and cognition of emergent situations.

One obstacle preventing patients’ use of HbSC is an economic problem. In the current situation in which the cost of inpatient hospice care is supported by health insurance, the payment of home care costs for each patient is a significant burden compared with inpatient care. However, if value and satisfaction for end-of-life patients are considered as the effectiveness, home-based palliative care is more cost-effective than inpatient hospice care. Therefore, it is essential to expand insurance support so that older patients with cancer can receive HbSC programmes free of the economic burden.

We systematically searched the literature on the effects of HbSC programmes on QoL of patients with advanced cancer. Unlike previous systematic reviews of the literature could not determine the efficiency of HbSC programmes on QoL,13 14 our study showed that HbSC programmes could be effective according to the content and aim of HbSC programme. However, this study has several limitations. First, as blinding and randomisation are difficult to accomplish in research on the current topic, there could be potential bias in the studies included in this systematic literature review. In all studies included, home care was provided to all patients enrolled in the intervention arm, and these patient populations were selected for vague inclusion criteria regarding the state of illness. Additionally, standard palliative care through outpatient clinics was provided to the control arm, which could have diluted the difference between the intervention and control groups. Second, there is also a possibility of information bias owing to language restriction. The current review only explored studies published in English. However, owing to varying cultural and medical backgrounds in different nations, studies conducted in various nations are likely to report different results. Third, there is a relative lack of quality studies evaluated highly according to SIGN criteria. As pain and QoL continually exacerbate, particularly in patients with advanced cancer, it is difficult to assess the impact of home care on QoL; a more sophisticated study design may be needed. It is needed that further research with delicately defined outcome indicators and more patients with identical cancer status.
