Reducing caregiver stress can improve caregiver quality of life as well as improve the care they provide to loved ones. This systematic review assesses the effectiveness of internet-based interventions to decrease caregiver stress. Materials and methods A comprehensive literature search of Ovid MEDLINE (1946–2013), Embase (1988– 2013), PsycINFO (1987–2013), and CINAHL was conducted using terms related to caregiver and internetbased interventions. Internet-based interventions involving informal caregivers in an open-label or randomized controlled trial setting were included. A pair of raters independently reviewed all published abstracts. Data regarding participants, interventions, and outcomes were extracted and, for randomized trials, methodology quality was also reviewed. Results Eight open-label trials met the review criteria: three showed positive benefit in reducing caregiver stress, four were partially positive (some outcomes positive, others negative), and one was a negative study. Sixteen randomized trials met the review criteria: six showed positive benefit, five were partially positive, and five were negative. There were no clear patterns as to the variables (such as study duration and complexity of intervention) associated with better outcomes, although earlier studies typically had more negative outcomes. Discussion Internet-based interventions were mostly effective in reducing aspects of caregiver stress and improving their well-being. Further studies to assess outcomes for caregivers and their recipients’ health, different technology delivery methods, and the cost of such interventions are needed. more apparent that caregiving for loved ones is burdensome, associated with fatigue, and impacts the health of the caregivers, therefore interventions are being designed to help address those concerns.3–7 Training and educational programs have been developed to provide support for the caregiver. These interventions have reduced caregiver burden and depression and improved well-being.6 8 However, due to the demands of caregiving, many of these face-to-face programs are inaccessible to caregivers. Therefore, technology-based interventions utilizing telephones, mobile phones, videophones, computers, and the internet are being developed to try to improve the caregiver’s ability to access help.4 In 2012 it was estimated that there were 2.4 billion internet users worldwide, with 274 million in North America.9 Internet usage, which provides people with abundant information and convenient ways of communicating, has become a regular activity of daily life. Internet-based programs have been shown to help people make health improvements such as smoking cessation or weight loss.10 11 Such programs have the advantage of being accessible 24 h a day and 7 days a week. Given that internet-based applications have been used to benefit patients with chronic illness, our research question was to find similar applications but with the target audience being caregivers. Surveying this field can help guide future application development. In this systematic review we identify open-label trials and randomized controlled trials (RCTs) of internet-based interventions to reduce caregiver burden. MATERIALS AND METHODS OBJECTIVE To cite: Hu C, Kung S, Rummans TA, et al. J Am Med Inform Assoc Published Online First: [ please include Day Month Year] doi:10.1136/amiajnl-2014002817 Non-professional caregivers, also known as informal caregivers who are usually family members, play an important role in caring for people who cannot care for themselves. There were an estimated 65.7 million informal caregivers in the USA in 2009, of which 66% (43.5 million) took care of an adult older than 50 years.1 It is expected that informal caregiving will be the largest source of long-term care services in the USA, increasing by 85% from 2000 to 2050.2 The roles and responsibilities of caregivers are complicated. Caregiving responsibilities are usually financially uncompensated, require the caregiver to juggle the responsibilities with other demands on their time, and often leave the caregiver exhausted and at risk for health problems. It is becoming Hu C, et al. J Am Med Inform Assoc 2014;0:1–11. doi:10.1136/amiajnl-2014-002817 The Cochrane Handbook for Systematic Reviews of Interventions guidelines was used.12 Inclusion criteria We included studies which met the following predetermined criteria: (1) non-professional (informal) caregivers of patients with chronic health problem; (2) internet-based technology delivering interventions to caregivers; (3) interventions designed to address caregiver stress, burden, or quality of life (QOL); and (4) open-label trials or RCTs published in peer-reviewed English language journals. Studies which did not incorporate formal measurement of caregiver stress, burden, or QOL were excluded from the summary tables but noted in the text. Studies which were not truly internet-based or web browser-based were also excluded, such as the older studies which used videophone technology or 1 Review older telephone modem connections, or studies which used only videoconferencing technology which was not internetbased. Studies which provided online education or information only, without any component of interactivity such as a discussion forum, were excluded because we wanted to assess internetbased studies which incorporated features of interaction. Two reviewers screened abstracts and, for those abstracts which appeared to meet the inclusion criteria, the full-text article was obtained and reviewed. Disagreements regarding whether an article met our inclusion criteria were resolved by applying the inclusion criteria again to the article and the two reviewers arriving at a consensus decision after further discussion. No numerical methods such as inter-rater scores were used. Search strategy The Ovid MEDLINE (1946 to September 2013), Embase (1988 to September 2013), PsycINFO (1987 to September 2013), and CINAHL databases were used. Search terms were caregivers AND evaluation/intervention AND technology OR blogging OR electronic mail OR internet OR software OR user-computer interface OR web based OR mobile OR cellular phone OR social media OR smartphone OR interactive OR Facebook OR twitter OR Tablet OR iPad OR distance learning OR Ehealth OR Online OR on-line OR Skype OR webcam OR Videophone OR Telemedicine OR Wireless OR wi-fi. Two reviewers (CH and SK) independently screened the article abstracts obtained from the search, and articles meeting the inclusion criteria were retrieved for full-text review. (performance and detection bias); (d) whether incomplete outcome data might affect the true study outcomes (attrition bias); (e) whether there was selective reporting (reporting bias); and (f ) the possibility of other bias. As recommended by the Cochrane Collaboration, we avoided the use of an overall summary category such as ‘high quality’ or ‘low quality’ to describe each study. Data extraction We extracted the following data: (1) participants (type of health problem of the care recipient, the number of participants in the intervention and control and other groups, caregiver mean age and gender; (2) intervention description (the intervention and comparison group(s) and study duration); (3) outcome measures and measurement timeline; and (4) study results (the effectiveness of intervention). RESULTS Two authors (CH and SK) independently screened 1474 article abstracts obtained from the search. Eleven abstracts were identified through bibliography and other search techniques. Of these combined 1485 abstracts, 162 reported on the same intervention and were excluded and a further 1014 did not meet the inclusion criteria. Three hundred and nine articles were retrieved for full-text review, resulting in 8 open-label trials and 16 RCTs included in the final analysis (figure 1). Table 1 presents the open-label studies which evaluated an intervention without a comparison group while table 2 contains those open-label studies which included a comparison group. Tables 3–6 summarize the RCTs. Risk of bias assessment The Cochrane Risk of Bias Tool was used for RCTs as we felt it has less meaning for open-label trials.12 Two reviewers (CH and SK) assigned ratings of ‘low,’ ‘high,’ and ‘unclear’ risk of bias for the following categories: (a) the adequacy of the sequence generation and randomization (selection bias); (b) the concealment of the treatment allocation (selection bias); (c) the adequacy of blinding of participants and research staff Participants The medical conditions of the care recipient ( patient) included cancer,30–32 dementia/neurodegenerative disease,13 16 22–24 28 pediatric traumatic brain injury,18–20 stroke,25 27 anorexia nervosa,34 35 schizophrenia,21 33 heart transplantation,17 frail elderly,14 hip fracture,15 infant/toddler sleep problem,36 and fetal alcohol spectrum disorders.37 Due to the nature of the Figure 1 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram.

However, some of the studies were able to include the patient and caregiver in trying to improve outcomes for both.15 17 19 20 27 30–33 In the eight open-label studies 289 caregivers and patients were enrolled and, in the 16 RCTs, 1882 caregivers were enrolled with 10 studies having fewer than 100 caregivers and six having more than 100. Interventions The internet interventions included interactive modules with study investigator assistance or community interactions. Five of the RCTs compared an internet intervention with standard care,23–25 28 33 six compared an internet intervention with unguided computer use or internet resources,19 20 27 30 31 34 three compared an internet intervention with added features to the same internet intervention,29 32 35 and two RCTs used a three-group design comparing the internet intervention with a control group and a third group of either higher or lower intensity than the intervention.36 37 About half of the RCTs had durations of 3 months or less.23 27–30 33 35–37 Outcome measures The included studies used formal rating scales to measure the outcomes related to caregiver stress, mood, anxiety, well-being, life satisfaction, or QOL. Secondary outcomes included internet program usage and satisfaction. A few studies measured patient healthcare utilization.25 34 36 Outcomes Of the eight open-label studies, three reported positive benefit in reducing caregiver stress as measured by their selected rating Hu C, et al. J Am Med Inform Assoc 2014;0:1–11. doi:10.1136/amiajnl-2014-002817 scales,13 16 22 four reported mixed results,14 17 18 21 and one reported a negative result.15 Of the 16 RCTs, six reported positive or mostly positive results,19 23 27 31 34 36 five reported mixed results with some of the outcome measures showing improvement28 32 35 37 or when taking into account factors such as socioeconomic status,20 and five reported negative results in the primary outcomes.24 25 29 30 33 These negative studies comprised most of the earlier studies with publication years 2002, 2005, 2006, 2009, and 2013. Risk of bias for RCTs A summary of the risk of bias for RCTs is shown in table 7. Keep in mind that the Cochrane Risk of Bias Tool is better suited to assessing the fidelity of randomized double-blind trials more along the lines of medication interventions. Also, these internet intervention studies were likely not designed with the Cochrane guidelines in mind (such as to describe the details of randomization), so there are many resulting ‘unclear’ conclusions. However, we include this assessment as it is recommended when evaluating randomized trials. Due to the nature of internet use, a careful control group and rigorous blinding are usually not possible. Participants in several studies in which the control group received usual care or no internet support still had their own computer and/or access to internet.30 33 For participants in the intervention groups there could be a wide range of times that they spent on the intervention. Several studies did not record internet usage factors such as time and frequency, making compliance difficult to assess, also resulting in potential bias.25 31 Another risk of bias relates to incomplete data and drop-out rates which might affect the true outcome of the study. Using criteria from a different set of guidelines, acceptable drop-out rates were based on the study duration: <20% for studies less 5 Review Table 5 Summary of randomized controlled trials of internet-based interventions for caregivers of patients with mental illness (schizophrenia or anorexia nervosa) Year/study Participants Interventions Outcome measures Results Comments 2005/Rotondi et al33 21 support persons and their patients with schizophrenia or schizoaffective disorder: 11 in intervention group and 10 in control.

Mean age not reported. Gender: 83% female than 3 months and <30% for studies more than 3 months.38 With these criteria, six of the short-term studies had acceptable drop-out rates19 20 23 27 33 36 and four did not.28 30 35 37 All five of the longer-term studies had drop-out rates >30%,24 25 31 32 34 with one study reporting >50% loss to follow-up.31 Most studies reported that the loss to follow-up was similar between groups except one study which reported more drop-outs in the control group24 and one study reporting more drop-outs in the intervention group.37 One study included intent-to-treat analysis27 and one study described the intention-to-treat analysis but did not report the resulting data.33 with providers or other caregivers.50 53–59 Some tested whether an in-person educational workshop could be equally effective when converted to an online format.47 60 Studies which were not internet web-based, such as purely videoconferencing or videophone-based, or those using older technology such as telephone dial-up modems, were also excluded.61–69 One study was excluded because the target audience was professional caregivers (ie, nursing home staff ) and the intervention was e-learning modules only.70 Overall, these studies showed a wide range of technologies and patient populations (dementia, cancer, brain injury, frail elderly patients, developmentally disabled patients, chronic illness, heart transplant, and schizophrenia). Excluded studies DISCUSSION Thirty-two open-label studies were not included in the tables because of our stringent inclusion criteria, but will be presented here in the text because they still demonstrate useful applications of computer-based technology for assisting caregivers. Several of these studies were proof-of-concept feasibility studies which measured usability, usage, and/or user satisfaction.39–43 We also excluded studies which did not measure outcomes related to reducing caregiver stress or improving caregiver QOL but instead might have measured caregiver knowledge, for example.39 44–52 Some of the interventions were only informational or educational without any interactive component such as a discussion forum or a method for the caregiver to interact In this systematic review of eight open-label trials and 16 RCTs of internet interventions to improve caregiver stress, we identified moderate evidence of benefit: nine trials were positive (three open-label studies and six RCTs), nine were partially positive (four open-label studies and five RCTs), and six were negative (one open-label study and five RCTs). Despite inherent differences in assessing the risk of bias for internet behavioral trials versus the traditional medication-based double-blind RCT, the quality of the RCTs was acceptable given the nature of the interventions. The evidence of benefit increases if the ‘partially positive’ category was reassigned to the positive category. In that case, 18 6 Hu C, et al.

Comments Did not describe dropout or sample size at the end of the intervention. Participants in the control group could still access the internet Low dropout rate. Reported that baseline measures and demographic characteristics of patients who dropped out were not significantly different between the two groups Unclear regarding dropout rate. Unclear regarding exact questions used to rate stress and social support. A few participants in the control group had access to the internet Research staff were not blinded to the groups. High and unequal dropout rate between intervention and control groups, with 28/66 patients (42%) lost to follow-up Participants and research staff were not blinded to group assignments, but ratings were made by parents and thus not vulnerable to influence by research staff. Dropout rates were different in intervention vs control, but not statistically significant. Families were allowed to keep computer equipment at treatment completion as an incentive for participation Dropout rates were high but equal between the intervention and control groups, and dropout reasons were adequately explained. Participants were offered the computer equipment for free at the end of the study, regardless of whether they were in the intervention or control group Dropout data were not clearly explained. In the intervention group there were 24/33 (72.7%) completers and in the control group there were 21/30 (70%) completers, approximately 30% dropout rate Caregivers (mothers) were not aware of the other groups. Significant sleep differences at baseline. Study sponsored by a commercial entity. Participants were paid $90–$175 depending on number of visits. Low dropout rate (3%) but unequal among the three groups Secondary analysis. Use of the intervention system was not mandated. Laptop and internet access were provided if needed. High dropout rate of 58%, 75 in intervention and 67 in control The researcher assessing outcomes was blinded to the intervention vs control group. Dropout information was adequately explained. Data analyzed with per-protocol and intent-to-treat Participants and research staff aware of group assignments (no blinding). Ratings were made by parents and thus not vulnerable to influence by research staff. Dropouts had higher depression and distress than completers but was adequately explained High dropout rate 20–40% similar across the three groups and adequately explained Secondary analysis: the study combined two randomized trials and the original randomized three-group design was reduced to two groups because of low recruitment. For data analysis the relevant groups were selected. Participants were supplied with a laptop if needed and allowed to keep it High dropout rate of 31%, with 29 in the intervention and 18 in the control. Caregivers with severe depression as measured by CES-D >30 were screened out 37 caregivers entered, 27 completed time 2 questionnaires but 30 (81%) completed the intervention. Of the 27, 5 did not access the website. Of the 7 who withdrew from the study, did not describe how many were from the intervention versus control Incomplete assessments were low (6–14%) and not statistically different between the two groups. Missing data were imputed Review trials (7 open-label studies and 11 RCTs) would be positive and 6 trials (1 open-label study and 5 RCTs) would be negative. The ‘partially positive’ results indicate that the study authors chose several measures to analyze, and some of the measures showed positive benefit while others did not. In newer study methodologies the authors frequently chose one primary outcome measure and several secondary outcomes measures, and declare the success of the study based on the primary outcome. Some of the articles reviewed defined a primary outcome, but we did not categorize those as a negative outcome if the primary outcome was negative but some of the secondary outcomes were positive. While our rigorous inclusion criteria regarding the type of trial (open-label studies and RCTs), the level of internet-based technology with some component of interactivity, and the need for formal outcome measures resulted in only 24 included trials, we explained in the Results section why we excluded 32 openlabel studies. Most of these excluded studies reported favorable outcomes in terms of feasibility, satisfaction, and benefit. Thus, in looking beyond the strict level of evidence that we used, we also found optimism that internet-based interventions can help caregivers. There were no clear factors such as duration or complexity to suggest what intervention approach might be more effective. The earlier studies tended to be negative, possibly related to older internet technology (some of these studies used internet TV) and less general comfort level with internet use. As technology improves, its access, ease of use, and acceptance increases. A few of the studies incorporated videoconferencing, which was a novel approach, especially in the earlier studies.19 20 24 Our findings are similar to those of other reviews of technology-based interventions. In a meta-analysis of 28 studies spanning 12 different illnesses, computer-mediated support group interventions increased social support and QOL and decreased depression.71 In a systematic review of patients with dementia in 15 studies, networked information and communication technology interventions showed moderate effects on improving caregiver stress and depression, although outcomes were inconsistent.72 In a newer systematic review which reported that internet-based interventions can improve aspects of the well-being of dementia caregivers, it was also noted that the overall level of evidence was low and lacked methodologic quality and that more randomized controlled studies are needed.73 one in cancer caregivers which identified needs as selfmanagement of distress and fostering of supportive family relationships75—can help developers design the content of internet-based interventions. Some of the elements can be used for both patient and caregivers and across different health conditions. For example, one such module might allow for selfassessment of mood using interactive questionnaires and subsequent multimedia education and management of mood, distress, and QOL. Other considerations in designing caregiver interventions would be whether the target audience should include patients. In a study delivering an in-person multidisciplinary group intervention targeting QOL of cancer patients, caregivers were also invited to some of the sessions.76 From this study, an analysis of the QOL of patients and caregivers showed that, when patients had better QOL, caregivers also had better QOL.77 It is intriguing to consider whether internet-based videoconferencing delivery of such an intervention might similarly benefit patients and caregivers. A recent review of consumer health information technology to support caregivers of patients with chronic illnesses identified several considerations for future study.4 Online modalities which promoted caregiver interactions, such as peer support groups and chat rooms, were found to be highly used and valued. These technologies can overcome barriers such as distance, travel logistics and cost, and limited caregiver time availability. There are still many gaps in our knowledge about best evidence for future technology-based interventions to help the caregiver. For example, exploration of age, gender, ethnic, and socioeconomic differences in responding to such interventions; inclusion of patient and caregiver dyads versus caregivers only; and use of technologies such as mobile devices, videoconferencing, or social media. One of our findings from this review is the diversity of methodologies used and patient illnesses addressed. To help improve comparability across studies, future trials can try to incorporate more widely used caregiver rating scales and be clearer about choosing a primary outcome measure and secondary measures. Involving the appropriate psychology and QOL researchers can help with measurement and methodology issues. Many of the studies we reviewed were already of high quality. As this field needs more exploration, open-label studies are beneficial but, in the future, more RCTs would help to answer the research question of whether caregivers actually benefit from these internetbased interventions. Future considerations There is currently a wide variety of caregiver internet-based interventions, as evidenced by our review findings and also the studies we excluded. Our opinion is that these interventions should take advantage of the interactivity possible through internet technologies, such as discussion forums and group videoconferencing, to connect caregivers with the medical team as well as peer support. In designing internet interventions for caregivers, the technology elements are similar to those for patients. A systematic review of web-based interventions for cancer patient empowerment identified commonly used elements such as education, self-monitoring, feedback/tailored information, self-management training, personal exercise program, and communication tools.74 In the caregiver interventions we reviewed, common elements also included education, information, self-management, and communication. Of course the target audience is different, so the content will be different, such as information relevant to the patient (eg, regarding diagnosis and treatment) versus relevant to the caregiver (eg, how to support the patient). Caregiver needs assessments—for example, Hu C, et al. J Am Med Inform Assoc 2014;0:1–11. doi:10.1136/amiajnl-2014-002817 CONCLUSION Internet-based interventions were mostly effective in reducing aspects of caregiver stress and improving their well-being. This systematic review of open-label studies and RCTs identified 24 such trials, with nine trials reporting positive benefits in the outcome measures, nine reporting partially positive outcomes, and six reporting no benefit of the internet-based intervention. With continued population acceptance of internet use, there are opportunities to use this platform to improve the lives of caregivers. Further studies are needed to assess outcomes for caregivers and their recipients’ health, different technology delivery methods, and the cost of such interventions.
