Policy Paper-Telemonitoring In Patients With CHF Essay

Telemonitoring of patients with congestive heart failure (CHF) is an important innovation with a potential of addressing the challenges and costs associated with the management of the CHF condition. To manage the effects of CHF across the affected population, multidisciplinary approaches are used as the best practice guidelines. For instance, multidisciplinary input, telephone support, and clinic visits are used to manage the CHF patients. However, the access to multidisciplinary programs among majority of the CHF patients is limited because of the barriers linked to financial costs and accessibility. Policy Paper-Telemonitoring In Patients With CHF Essay. As a result, telemonitoring approaches must be developed and used to foster the effective management of CHF patients with the aim of improving their quality of life, while reducing the costs associated with hospitalization.
The need for changing the policy is supported by diverse researches that indicate the high prevalence of CHF in the general population. For instance, more than six million Americans are suffering from CHF, which is considered as a major cause of hospitalization for individuals under the Medicare plan. In addition, the current state of affairs must be changed based on the need to reduce the costs of CHF patients’ hospitalization, which are over $30 billion each year. With the use of appropriate telemonitoring instruments, including computers and telephones, hospitals are able to reduce the costs related to patient follow-ups and hospital readmission (Clarke, Shah, & Sharma, 2011).
The recommended changes include the development of a working strategy that can foster the delivery of the required care services to CHF patients through appropriate telemonitoring approaches. Relevant telemonitoring instruments should be installed in the health care settings to allow nurses, clinicians, and other medical personnel to monitor the progress of patients who have been discharged from hospitals (Polisena, et al., 2010). The remote monitoring of the patients through effective telemonitoring innovations is crucial toward addressing the patients’ conditions in a timely manner, thereby avoiding hospital readmissions.
The strategies necessary toward introducing the policy for review entail holding consultations with relevant stakeholders within the heath care sector to garner their support in relation to the introduction and use of telemonitoring in the management of CHF patients.Policy Paper-Telemonitoring In Patients With CHF Essay.  Based on the appropriate discussions, the policy will be introduced for review with the intention of determining its benefits in reducing costs and improving the CHF patients’ quality of life. The discussions will be held with nurses and clinicians alongside their professional affiliations, and health care institutions, including medical clinics and hospital systems. Additionally, health care policymakers at different levels, including state, federal, and local levels will be consulted. These agencies are selected based on the need to obtain the financial support required for the acquisition of the necessary telemonitoring resources (Anker, Koehler, & Abraham, 2011).


In summary, telemonitoring is an innovation that has a higher potential of improving health care delivery to CHF patients with the aim of eliminating hospital readmissions while minimizing the costs of managing the condition. Health care providers should change the state of affairs by integrating relevant technology instruments, including computers and telephones, to provide remote services to CHF patients. To achieve an effective adoption and implementation of the policy change, relevant stakeholders, including nurses, clinicians, and governmental agencies must be involved in the change process. This involvement of such stakeholders will lead to the successful integration of telemonitoring resources in health care settings, thereby contributing to the effective delivery of care to CHF patients.

Background: Many systematic reviews exist on the use of remote patient monitoring (RPM) interventions to improve clinical outcomes and psychological well-being of patients with heart failure. However, research is broadly distributed from simple telephone-based to complex technology-based interventions. The scope and focus of such evidence also vary widely, creating challenges for clinicians who seek information on the effect of RPM interventions.

Objective: The aim of this study was to investigate the effects of RPM interventions on the health outcomes of patients with heart failure by synthesizing review-level evidence.

Methods: We searched PubMed, EMBASE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Library from 2005 to 2015. We screened reviews based on relevance to RPM interventions using criteria developed for this overview. Independent authors screened, selected, and extracted information from systematic reviews. AMSTAR (Assessment of Multiple Systematic Reviews) was used to assess the methodological quality of individual reviews. We used standardized language to summarize results across reviews and to provide final statements about intervention effectiveness.

Results: A total of 19 systematic reviews met our inclusion criteria. Reviews consisted of RPM with diverse interventions such as telemonitoring, home telehealth, mobile phone–based monitoring, and videoconferencing. Policy Paper-Telemonitoring In Patients With CHF Essay. All-cause mortality and heart failure mortality were the most frequently reported outcomes, but others such as quality of life, rehospitalization, emergency department visits, and length of stay were also reported. Self-care and knowledge were less commonly identified.

Conclusions: Telemonitoring and home telehealth appear generally effective in reducing heart failure rehospitalization and mortality. Other interventions, including the use of mobile phone–based monitoring and videoconferencing, require further investigation.

Prior Work

Heart failure is a complex chronic condition that presents debilitating symptoms [1]. There is a high prevalence of heart failure worldwide [2] and, despite advanced medical, pharmacological, and surgical treatment, patient outcomes are poor and hospital readmissions are high [1].

Heart failure clinical outcomes depend largely on how well people self-manage their condition between face-to-face office visits with health care providers. Hence, lack of symptom monitoring and seeking treatment when necessary, particularly between their visits, may result in hospital readmissions in this population. To avoid heart failure exacerbation, patients are encouraged to modify their lifestyle and constantly monitor symptoms related to their condition [1]. Providing patients with the tools to take an active, participatory role in their disease progression and management is important [3].

The high health care costs and poor quality associated with heart failure have led to the development of remote patient monitoring (RPM) systems and cost-effective disease management strategies. RPM uses devices to remotely collect and send data to a health care facility for diagnostic interpretation or monitoring purpose. Such applications might monitor specific vital signs, such as blood pressure, heart rate, or electrocardiogram (ECG), or a variety of indicators for housebound patients. Such systems can be used to facilitate health care by nurses who visit patients at home [4]. RPM comprises a range of noninvasive and patient monitoring approaches that could improve quality of life (QOL) of patients with heart failure who are at high risk of deterioration [5].

The current literature contains research results from numerous trials investigating the clinical, structural, behavioral, or economic effects of RPM interventions on patients with chronic diseases [6]. Policy Paper-Telemonitoring In Patients With CHF Essay. Recent evidence suggests that RPM component systems have beneficial effects on mortality and hospitalization of patients with heart failure [5]. However, the scope, methods of analysis, results, and quality of systematic reviews are varied and this may cause uncertainty for policy makers, health professionals, and others regarding utilization of the information from existing evidence. Investigating the effect of a wide range of RPM systems on heart failure outcomes is a key aspect in improving such technology-based interventions, but taking it in isolation fails to consider the strength, weakness, and implications for future research.


We undertook this overview to systematically gather, evaluate, and organize the review-level evidence. The aim of this study was to report the highest level of evidence and to identify the RPM intervention that is most effective in improving the clinical outcomes of patients with heart failure. It also aimed to identify existing gaps in this area and to recommend avenues for future research.


Inclusion and Exclusion Criteria

The included records were assessed for eligibility against the study’s inclusion criteria including types of reviews, participants, interventions, and outcomes.

Types of Reviews

Previous systematic reviews and meta-analyses evaluating the effects of RPM on heart failure and published in peer-reviewed journals or the Cochrane Library were considered eligible for inclusion. Policy Paper-Telemonitoring In Patients With CHF Essay. Key characteristics of inclusion criteria outlined by the Cochrane Collaboration [7] were used to determine the types of reviews. Depending on the method for analyzing the evidence from primary studies, systematic reviews can be classified as qualitative or narrative reviews and quantitative reviews. We included only quantitative systematic reviews. Conference proceedings, review summaries, editorials, and unpublished studies were excluded.

Types of Participants

Patients with a diagnosis of heart failure regardless of age, sex, or ethnicity were considered in this review. However, the diagnostic criteria should have been established in the included reviews using standard criteria and New York Heart Association functional classification. Reviews with mixed population were also excluded from this study.

Types of Interventions

We considered systematic reviews and meta-analyses that investigated the effectiveness of RPM interventions for patients with heart failure. These interventions applied information and communication technology (ICT) for mentoring, supporting physical or mental health, and/or monitoring of any vital signs, biometric and/or data related disease (signs and symptoms) from patients to health care providers. The systematic reviews that only investigated the effect of telediagnosis were excluded. We also excluded structured telephone support from this overview because the definition of RPM used in this overview considered structured telephone support distinctly different from RPM interventions.

Types of Outcomes

We sought data for outcomes in the following categories:

  • Patient-oriented outcomes, such as knowledge and self-care, health status, and well-being
  • Health service–oriented outcomes, which include rehospitalization, emergency department visits, and length of stay

Reviews were included if the primary or secondary outcomes from included studies were related to the clinical or behavioral effects of RPM on patients with heart failure. Systematic reviews and meta-analyses that investigated only the cost, feasibility, or uptake of RPM systems were excluded. Policy Paper-Telemonitoring In Patients With CHF Essay.

Search Methods for Identification of Studies

A comprehensive and systematic search was performed using the electronic sources PubMed, EMBASE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Library from 2005 to 2015. A sensitive search strategy was developed and refined by an experienced medical information specialist. A combination of MeSH (Medical Subject Headings) terms as well as key terms related to telemedicine, heart failure, and systematic reviews were used to search PubMed for all relevant studies. This search strategy was modified for searching the other databases according to their user guide. Details of the search strategy are presented in Multimedia Appendix 1.

Data Collection and Analysis

Selection Procedure

Studies reviewing telemonitoring, telehealth, and remote monitoring outcomes in patients with heart failure were selected by 2 independent reviewers. Records that did not clearly meet the inclusion criteria were excluded. Studies were excluded if they investigated the effects of RPM on patients with mix of chronic diseases. As shown in Figure 1, our initial search resulted in 2133 records. The reviewers read all titles and abstracts to remove duplicate studies (219). On the basis of the inclusion criteria, nonrelevant records were excluded (1864). If there was any discrepancy, the reviewers discussed the issues and reached a consensus. Because of resource limitation, reviews published in languages other than English were excluded from the analysis. A number of records (11) were excluded as they were not systematic reviews, and 20 systematic reviews were excluded because of the following reasons: wrong interventions, economic analysis, or other reasons. This yielded a final number of 19 systematic reviews included in this study.

Summaries of Reviewed Systematic Reviews

To allow consistent reporting of results across reviews, we extracted and descriptively summarized each study’s results using standardized language.Policy Paper-Telemonitoring In Patients With CHF Essay.  Then we summarized and narratively reported results of the reviews to enable identification of broad conclusions within and across reviews. A table was developed to extract key characteristics of each review (Table 1). The information sought included general details related to systematic reviews (eg, authors and year of publication) and more specific details about the types of interventions, outcome variables, sample (number of included studies in each review), results, and methodological shortcomings.

Methodological Quality of Reviewed Studies

The methodological quality of included systematic reviews and meta-analyses was examined by using the Assessment of Multiple Systematic Reviews (AMSTAR) tool [27]. The tool is a validated instrument and assesses the degree to which review methods avoided bias by evaluating the methods against 11 distinct criteria. The process of scoring was performed by independent assessors. Each AMSTAR item was rated as yes (clearly done), no (clearly not done), can’t answer, or not applicable, based on the published review report. A review that adequately met all of the 11 criteria was considered to be a review of the highest quality. The quality rating was as follows: AMSTAR score (out of 11 criteria) rating 8 to 11 as high quality, 4 to 7 as moderate quality, and 3 or lower as low quality.

As reported by the authors of this overview, systematic reviews included studies that ranged from high (well-designed and well-conducted studies) to low quality (studies with serious methodological limitations; Table 2). A small number of reviews were highly selective about the quality of the studies they included; for example, 3 systematic reviews [9,17,21] specified that only randomized controlled trials (RCTs) were eligible for inclusion. However, these measures did not ensure that included studies were of high quality.

Question 1: A Priori Design

Only 3 reviews [9,11,18] included in this study established inclusion criteria and a priori design before commencing with the literature search, data collection, and abstraction. The rest of the systematic reviews did not frame their research inclusion criteria and lacked a priori design.

Question 2: Duplicate Study Selection and Data Extraction

Of 19 reviews, in 10 reviews [811,13,14,1618,20] the process of screening was performed by 2 independent authors. In 8 reviews the authors did not clarify this process [12,15,19,2226]. Policy Paper-Telemonitoring In Patients With CHF Essay.

Question 3: Comprehensive Search

The analysis of this question, which required at least two electronic sources and one supplementary strategy in order to be scored as comprehensive search, showed that all reviews used at least two electronic databases to search primary studies. The frequently used databases were MEDLINE, CINAHL, and EMBASE. Although all reviews reported the years and databases searched, only 12 reviews had comprehensive literature review based on the AMSTAR criteria [8,9,11,12,14,16,17,1922,25].

Question 4: Inclusion of Gray Literature

Among 19 reviews included in this overview, only 5 reviews reported searching for gray literature regardless of their publication type [8,9,11,21,25]. Most reviews focused on primary studies that were published in English-language journals.

Question 5: Included and Excluded Studies Provided

Most reviews presented a list of included studies. However, only 2 reviews [19,22] reported a list of excluded studies in their article or as a supplementary material.

Question 6: Characteristics of the Included Studies

Characteristics of the original studies with respect to the participants, intervention, and outcomes were presented in 15 reviews in the form of a table or illustration [811,13,15,16,1825]. A range of characteristics from primary studies such as the mean age of patients, duration of follow-up, and severity of disease was reported in the reviews.

Question 7: Quality Assessment of the Primary Studies

The methodological quality or risk of bias of primary studies included in the reviews was appraised in 10 reviews [8,9,11,12,14,18,2022,25] out of the 19 reviews. These 10 systematic reviews provided their methods to assess included studies either using a quality scale (such as checklist with composite scores) or predefined risk of bias criteria. Furthermore, the quality of individual studies was reported in a meaningful format of a grade or score by these reviews.

Question 8: Scientific Quality of Included Studies Used Appropriately in Formulating Conclusions

Out of the 19 reviews, 7 reviews [8,9,11,14,21,22,25] formally assessed the scientific rigor of the primary studies and integrated the results of the methodological quality into the final conclusions and made recommendations for future studies.

Question 9: Appropriateness of Methods Used to Combine Studies’ Findings

There were 7 reviews [810,13,18,19,21] that used a specific method such as chi-square test to combine the results. Policy Paper-Telemonitoring In Patients With CHF Essay.

Question 10: Publication Bias

The risk of publication bias was reported in 2 reviews [9,13]. As shown in Table 2, the rest of the systematic reviews did not assess publication bias.

Table 1. Characteristics of the included systematic reviews.
View this table
Question 11: Conflicts of Interest

Interestingly, 10 reviews [911,13,16,18,21,22,24,25] provided information related to the project’s source of funding and conflict of interest. Assessing the methodological quality of included systematic reviews and meta-analyses revealed that the quality of 12 systematic reviews [8,10,11,13,14,16,1822,25] was moderate as they were scored between 4 and 7. A total of 6 systematic reviews [12,15,17,23,24,26] had a very low quality (scored 3 and less) and only 1 systematic review was identified as highest quality (scored 10) [9]. Overall, many of the reviews displayed important limitations. For example, only 3 systematic reviews [9,11,18] had referred to their a priori design, such as a published protocol, and 2 systematic reviews [9,13] assessed the likelihood of publication bias of reviewed studies.

Synthesis of Results and Rating the Evidence of Effectiveness

We applied 4 steps in developing the data integration tables based on the study by Ryan et al [28]. These were first identifying, extracting, and summarizing relevant information from each review for a comprehensive picture of the characteristics of the systematic review. Second, results for the outcomes of the review were assessed and translated to standardized statements. Policy Paper-Telemonitoring In Patients With CHF Essay. Third, results including RPM interventions and heart failure outcomes were mapped onto a taxonomy (Table 3) using language specific to the field of RPM interventions. Fourth, the implications of the review were assessed after the mapping step clarified the level of evidence available for each intervention. These steps were taken to assist with synthesizing and rating the evidence across systematic reviews with complex and diverse interventions [28].


Types of Interventions

This overview appraised and summarized 19 systematic reviews that consisted of a broad range of RPM interventions such as telemonitoring (telemonitoring includes the collection and transmission of clinical data between a patient at a distant location and a health care provider through a remote interface so that the provider may conduct a clinical review of such data or provide a response relating to such data) [29], home telehealth (home telehealth comprises remote health care delivery or monitoring between a health care professional and a patient outside of clinical settings, in their home or assisted living residence) [29], and integration of electronic transfer of physiological data via mobile phones, wearable electronic devices, or implantable electronic devices. Table 1 provides a summary of the reviews’ characteristics that focused on RPM in heart failure outcomes. Studies were published from 2006 to 2015 and consisted of a minimum of 4 [23] and a maximum of 56 original studies [24] with the methodology of RCT, cohort studies, and/or pre-post studies. The follow-up period ranged from 1 to 26 months.

Table 4 shows that 13 systematic reviews investigated the effect of telemonitoring and home telehealth. Among these, 4 reviews [9,11,12,21] investigated the effect of structured telephone support but as mentioned earlier, the results related to structured telephone support excluded from this review. One systematic review included 3 RCTs that examined the effect of videoconferencing and compared the intervention with usual care or telephone support [8]. One RCT and 1 pre-post study cited by 2 systematic reviews [10,23] examined mobile phone interventions. In 1 systematic review [10], 11 RCTs investigated the effect of PDAs. The devices used in those RCTs were widely varied. A total of 4 systematic reviews investigated the effect of home telehealth on heart failure clinical outcomes. Policy Paper-Telemonitoring In Patients With CHF Essay.

View this table


Among 19 reviews, 16 reviews [811,13,14,1625] reported the mean or range of participants’ age and/or New York Heart Association heart failure classification. The highest reported mean age was 86 years [16] and the lowest was 44 years [16]. Of the reviews, 10 systematic reviews [811,13,1618,20,25] documented the New York Heart Association classes I-IV, 2 systematic reviews reported classes II-IV [21,22], 1 systematic review reported classes III-IV [19], and 1 systematic review described participants as having a mild or moderate class of heart failure [14]. The rest of the reviews did not report heart failure classification (Table 1). One systematic review investigated studies focused on patients with heart failure following discharge after a recent episode of hospitalization [11].

Effect of Interventions or Clinical Outcomes

Statements related to intervention effectiveness were determined using the evidence rating scheme for each review and summarized within each intervention category (Table 4). Out of 19 systematic reviews, 9 reviews showed a reduction in all-cause mortality [811,13,16,17,20,21] and 5 reviews showed a reduction in all-cause hospitalizations [11,18,19,23,25]. A total of 6 reviews reported a reduction in heart failure hospitalization [8,11,17,2022], 2 reviews reported a reduction in length of hospital stay [9,11], and 1 systematic review reported a reduction in emergency department visits [18].Policy Paper-Telemonitoring In Patients With CHF Essay.  Improvement of QOL was reported in 3 reviews [11,21,23] and self-care in 1 review [15].

Telemonitoring has been shown to reduce mortality (risk ratio, RR, 0.66, 95% CI 0.54-0.81, P<.001) [9]. Also, 24 hours telemonitorirng over 7 days (hazard ratio 0.76, 95% CI 0.49-1.18), and telemonitoring during office hours (hazard ratio 0.62, 95% credible interval 0.42-0.89) [11], (risk ratio 0.77, 95% CI= 0.61-0.97, P ≥.01 ) [21], (odds ratio 0.53,CI 0.36-0.80) [8] has reduced the rate of HF mortality. The significant effect of telemonitoring on health care utilization was also reported in several systematic reviews (risk ratio 0.72, 95% CI 0.61-0.85) [13], (odds ratio 0.64, 95% CI 0.39-0.95) [8], (risk ratio 0.79, 95% CI 0.67-0.94, P>.001) [21], (RR 0.93, 95% CI 0.87-0.99, P ≥.01) [19]. policy Paper-Telemonitoring In Patients With CHF Essay.
