Summary of Clinical Research on Using Remote Patient Monitoring to Manage Chronic Kidney Disease

Practical Use of Home Blood Pressure Monitoring in Chronic Kidney Disease

Source: Cardiorenal Medicine

Despite the availability of blood pressure (BP)-lowering medications and dietary education, hypertension is still poorly controlled in the chronic kidney disease (CKD) population. As glomerular filtration rate declines, the number of medications required to achieve BP targets increases, which may lead to reduced patient adherence and therapeutic inertia by the clinician.

Home BP monitoring (HBPM) has emerged as a means of improving diagnostic accuracy, risk stratification, patient adherence, and therapeutic intervention. The definition of hypertension by HBPM is an average BP >135/85 mm Hg. Twelve readings over the course of 3-5 days are sufficient for clinical decision making. Diagnostic accuracy is especially important in the CKD population as approximately half of these patients have either white coat hypertension or masked hypertension.

Preliminary data suggest that HBPM outperforms office BP monitoring in predicting progression to end-stage renal disease or death. When combined with additional support such as telemonitoring, medication titration, or behavioral therapy, HBPM results in a sustained improvement in BP control. HBPM must be adapted to provide information on the phenomena of nondipping (absence of nocturnal fall in BP) and reverse dipping (paradoxical increase in BP at night). These diurnal patterns are more prevalent in the CKD population and are important cardiovascular risk factors.

Ambulatory BP monitoring provides nocturnal BP readings and unlike HBPM may be reimbursed by Medicare when certain criteria are met. Further studies are needed to determine whether HBPM is cost-effective in the current US healthcare system.

Home and ambulatory blood pressure monitoring in chronic kidney disease

Source: Current Opinion in Nephrology and Hypertension

Purpose of review: Whereas blood pressures (BPs) obtained in the clinic have formed the basis of diagnosis and treatment of hypertension among patients with chronic kidney disease (CKD), home and ambulatory BP monitoring obtained outside the physician's office have emerged as viable alternatives for the surveillance of hypertension. The purpose of this review is to discuss the recent advances in out-of-office BP recordings in the management of patients with CKD including those on hemodialysis.

Recent findings: In patients with CKD not yet on dialysis, hypertension is often seemingly difficult to control in part because of 'white-coat hypertension'. Masked hypertension is seen in about 8% of patients. Nondipping ambulatory BP manifests early in the course of CKD but may not be independently associated with end-stage renal disease. Out-of-office measured BPs better predict end-organ damage and mortality outcomes in CKD and hemodialysis patients. The analysis of patterns of ambulatory BP monitoring has revealed that elevated BP in these patients is associated with increased arterial stiffness and a blunted rate of rise in BP between dialysis with volume overload.

Summary: It is recommended that the diagnosis and treatment of hypertension among patients with CKD is best done with home (or ambulatory) BP monitoring.

Out-of-office blood pressure monitoring in chronic kidney disease

Source: Blood Pressure Monitoring

Blood pressure (BP) control is vital to the management of patients with chronic kidney disease (CKD) yet most treatment decisions use BPs obtained in the clinic. The purpose of this report is to review the importance of self-measured and automatic ambulatory BPs in the management of patients with CKD.

Compared with clinic-obtained BPs, self-measured BP more accurately defines hypertension in CKD. Masked hypertension seems to be associated with higher risk of end-stage renal disease in CKD patients. Conversely, white-coat hypertension seems to be associated with better renal outcomes than those who have persistent hypertension.

Ambulatory BP monitoring is the only tool to monitor BP during sleep, diagnose nondipping, and, as self-measured BPs, have greater prognostic power in CKD compared with clinic BP. In hemodialysis patients, self-measured BP, but not pre/post-dialysis BP, shares the combination of high sensitivity and high specificity of greater than 80% to make a diagnosis of hypertension with the reference standard of ambulatory BP monitoring. In addition, self-measured and ambulatory BPs seem to be better correlates of left-ventricular hypertrophy and mortality in hemodialysis patients compared with pre/post-dialysis BP.

Emerging data suggest that out-of-office BP monitoring is superior to BP obtained in the clinic when predicting target-organ damage and prognosis. Out-of-office BP monitoring is recommended for the management of hypertension in all stages of CKD.

The utility of remote patient management in peritoneal dialysis

Source: Clinical Kidney Journal

Methods and results: Remote patient management (RPM) programs are one of the most crucial innovations in the peritoneal dialysis (PD) field that have been developed in the last decade. RPM programs are associated with favourable clinical outcomes by increasing the adherence of the patients to PD prescription. The literature supports that RPM is associated with increased blood pressure control and technique survival, and decreased hospitalization rate, length of hospital stay and health costs. RPM programs also facilitate patient follow-up during the coronavirus disease 2019 pandemic, increase treatment adherence and lead to better clinical outcomes. However, published data remain scarce and mainly consist of observational or retrospective studies with relatively low numbers of patients. Therefore, randomized controlled trial results will be more informative to demonstrate the effect of RPM programs on clinical outcomes.

Impact of remote biometric monitoring on cost and hospitalization outcomes in peritoneal dialysis

Source: Journal of Telemedicine and Telecare

Introduction: Peritoneal dialysis is a home-based therapy for individuals with end-stage renal disease. Telehealth, and in particular - remote monitoring, is making inroads in managing this cohort.

Methods: We examined whether daily remote biometric monitoring (RBM) of blood pressure and weight among peritoneal dialysis patients was associated with changes in hospitalization rate and hospital length of stay, as well as outpatient, inpatient and overall cost of care.

Results: Outpatient visit claim payment amounts (in US dollars derived from CMS data) decreased post-intervention relative to pre-intervention for those at age 18-54 years. For certain subgroups, non- or nearly-significant changes were found among female and Black participants. There was no change in inpatient costs post-intervention relative to pre-intervention for females and while the overall visit claim payment amounts increased in the outpatient setting slightly (US$511.41 (1990.30) vs. US$652.61 (2319.02), p = 0.0783) and decreased in the inpatient setting (US$10,835.30 (6488.66) vs. US$10,678.88 (15,308.17), p = 0.4588), these differences were not statistically significant. Overall cost was lower if RBM was used for assessment of blood pressure and/or weight (US$-734.51, p < 0.05). Use of RBM collected weight was associated with fewer hospitalizations (adjusted odds ratio 0.54, 95% confidence interval 0.33-0.89) and fewer days hospitalized (adjusted odds ratio 0.46, 95% confidence interval 0.26-0.81). Use of RBM collected blood pressure was associated with increased days of hospitalization and increased odds of hospitalization.

Conclusions: RBM offers a powerful opportunity to provide care to those receiving home therapies such as peritoneal dialysis. RBM may be associated with reduction in both inpatient and outpatient costs for specific sub-groups receiving peritoneal dialysis.

Remote Patient Monitoring Program in Automated Peritoneal Dialysis: Impact on Hospitalizations

Source: Peritoneal Dialysis International

Background: Automated peritoneal dialysis (APD) is a growing PD modality but as with other home dialysis methods, the lack of monitoring of patients' adherence to prescriptions is a limitation with potential negative impact on clinical outcome parameters. Remote patient monitoring (RPM) allowing the clinical team to have access to dialysis data and adjust the treatment may overcome this limitation. The present study sought to determine clinical outcomes associated with RPM use in incident patients on APD therapy.

Methods: A retrospective cohort study included 360 patients with a mean age of 57 years (diabetes 42.5%) initiating APD between 1 October 2016 and 30 June 2017 in 28 Baxter Renal Care Services (BRCS) units in Colombia. An RPM program was used in 65 (18%) of the patients (APD-RPM cohort), and 295 (82%) were treated with APD without RPM. Hospitalizations and hospital days were recorded over 1 year. Propensity score matching 1:1, yielding 63 individuals in each group, was used to evaluate the association of RPM exposure with numbers of hospitalizations and hospital days.

Results: After propensity score matching, APD therapy with RPM (n = 63) compared with APD-without RPM (n = 63) was associated with significant reductions in hospitalization rate (0.36 fewer hospitalizations per patient-year; incidence rate ratio [IRR] of 0.61 [95% confidence interval (CI) 0.39 - 0.95]; p = 0.029) and hospitalization days (6.57 fewer days per patient-year; IRR 0.46 [95% CI 0.23 - 0.92]; p = 0.028).

Conclusions: The use of RPM in APD patients is associated with lower hospitalization rates and fewer hospitalization days; RPM could constitute a tool for improvement of APD therapy.

Clinical and social advantages of remote patient monitoring in home dialysis

Source: Italian Journal of Nephrology

Introduction: Home dialysis (both extracorporeal and peritoneal) can improve the management and the quality of life of patients with chronic disease. In this study we evaluated the possible clinical and social advantages derived from remote patient monitoring using the Doctor Plus® Nephro program, as opposed to the standard of care.

Methods: We included in our analysis the patients participating in the remote monitoring program of the Nephrology Center of ASL 3 in Rome from July 2017 to April 2019. Each patient was observed from a minimum of 4 months to a maximum of 22 months. Systolic and diastolic pressure, heart rate, weight and oximetry were monitored. An SF-12 questionnaire was also administered to evaluate the level of satisfaction with the program Doctor Plus® Nephro.

Results: 16 patients (56,3% males, mean age 62 years) were observed as part of the analysis. During the program there was a reduction of systolic pressure in 69% of the patients and of diastolic pressure in 62,5%. Mean heart rate decreased from 69,4 bpm to 68,8 bpm (p<0,0046). The answers to the SF-12 questionnaire showed that the perceived health status of all patients had improved. Due to the closer clinical monitoring, the number of patients accessing emergency services also decreased.

Conclusion: Doctor Plus® Nephro could improve access to home treatment; the results of this study in fact show it to be a useful tool for Nephrological Centers to monitor patients undergoing home dialysis.

Clinicians' experiences with remote patient monitoring in peritoneal dialysis: A semi-structured interview study

Source: Peritoneal Dialysis International

Background: Fear of catastrophic events and uncertainty about safety at home are barriers to choosing peritoneal dialysis (PD). Remote monitoring may address these concerns and is increasingly being used in patients on automated peritoneal dialysis (APD). This study aims to describe clinicians' perspectives and experiences of remote monitoring in caring for patients on PD.

Methods: We conducted semi-structured interviews with nephrologists and dialysis nurses across nine dialysis units in New Zealand who had experience using remote monitoring with patients on APD. Interviews were transcribed and analysed using thematic analysis.

Results: Thirteen registered nurses and 12 nephrologists or nephrologists-in-training (total N = 25) participated. Four themes were identified: promoting and maintaining PD (providing reassurance to patients through continual surveillance, supporting confidence at home and sustaining PD as the patient-preferred treatment); enabling data-driven decisions (using comprehensive clinical data in providing timely and accessible care, and identifying and supporting patient adherence); establishing boundaries for use (negotiating privacy and independence, clarifying clinician and patient responsibilities and strengthening nursing innovation and capability); and enhancing patient-focused care (developing empathy for patients, enabling self-management and reducing time and financial burden in accessing care).

Conclusions: Remote monitoring is valued by clinicians in promoting and maintaining patients on PD and enabling data-driven decisions. Remote monitoring enhances patient-focused care, but clinicians also emphasise the need to protect patient privacy and establish boundaries for use. Remote monitoring that supports the clinicians' role and adheres to principles of data security maintains patient privacy may enhance care and outcomes for patients on PD.

Remote Patient Management in Peritoneal Dialysis Improves Clinical Outcomes

Source:  Contributions to Nephrology

Chronic diseases are a global concern and a leading cause of death and disability. These conditions require intensive and ongoing medical assistance to maximize outcomes and avoid the risk of frequent flare-ups and hospitalizations, which increase the cost of healthcare. Remote patient management (RPM) is a strategy that allows for accurate home monitoring of chronic patients, enabling the team to improve care through prevention and early identification of problems, with consequent timely interventions. Peritoneal dialysis (PD) is a home-based therapy representing an ideal model for testing the ability of RPM to improve clinical outcomes by allowing the 2-way link between health providers and patients.

The literature and our own results confirm that RPM applied to automated peritoneal dialysis (APD) allows an efficient use of healthcare resources, helping to improve tailoring of APD prescription and to intervene early with troubleshooting, reducing the frequency of in-person visits for emergency problems. RPM-APD is today made possible by a cloud-based software providing bidirectional communication between patient's home and the hospital care team (Cycler HOMECHOICE CLARIA with SHARESOURCE platform). This approach can be useful in promptly identifying patients with higher risk of complications: a knowledge-based management permits the reduction of urgent events, and the prevention of clinical complications improving patient outcomes. In our experience, matured over 2 years in a cohort of prevalent patients, we observed a significant reduction of patient drop-out and technique failure, the number of scheduled and unscheduled hospital visits, the number of episodes of overhydration, rate of hospitalization, episodes of non-compliance to prescription, patient and hospital team time spent in travelling and management of therapy, healthcare costs and patient's expenditure, miles travelled by patients from home to hospital and vice versa.

The cost/benefit analysis is strongly in favor of the RPM-APD modality versus the traditional periodic hospital visit regime.

The advantages of remote patient monitoring in automated peritoneal dialysis

Source: Italian Journal of Nephrology

The follow-up automated peritoneal dialysis (APD) patients has been recently improved as data can be transmitted remotely to an internet cloud. The introduction of remote patient monitoring (RPM) technologies also allows a better clinical control and tailoring of dialysis treatment through a web-based software (Claria-Sharesource Baxter). The aim of the present study is to determine the impact of RPM in a single center, both in clinical and organizational terms, compared to traditional technologies.

We studied 26 prevalent APD patients aged 69±13 years, observing them for a period of six months while using the traditional technology and then further six months using the new technology. The patients had been on dialysis for 9 months before the start of the study and a relevant portion of them lived in mountainous or hilly areas. Our study shows an increase in the number of proactive calls from the center to the patients, a reduction of anxiety in patients and caregivers, an earlier detection of clinical problems, a reduction of unscheduled (urgent) visits and finally a reduction of hospitalizations after the adoption of RPM software.

In our experience, the RPM system showed a good performance and a simple interface, allowing for the precise assessment of daily APD. Furthermore, RPM system improved the interaction between patients and healthcare providers, with a significant benefit in terms of safety and of care quality.

Pilot health technology assessment study: organizational and economic impact of remote monitoring system for home automated peritoneal dialysis

Source: International Urology and Nephrology

Purpose: Follow-up of automated peritoneal dialysis (APD) has been improved by data transmission by cellular modem and internet cloud. With the new remote patient monitoring (RPM) technology, clinical control and prescription of dialysis are performed by software (Baxter Claria-Sharesource), which allows the center to access home operational data. The objective of this pilot study was to determine the impact of RPM compared to traditional technology, in clinical, organizational, social, and economic terms in a single center.

Methods: We studied 21 prevalent APD patients aged 69 ± 13 years, on dialysis for a median of 9 months, for a period of 6 months with the traditional technology and 6 months with the new technology. A relevant portion of patients lived in mountainous or hilly areas.

Results: Our study shows more proactive calls from the center to patients after the consultation of RPM software, reduction of calls from patients and caregivers, early detection of clinical problems, a significant reduction of unscheduled visits, and a not significant reduction of hospitalizations. The analysis also highlighted how the RPM system lead to relevant economic savings, which for the health system have been calculated € 335 (mean per patient-month). With the social costs represented by the waste of time of the patient and the caregiver, we calculated € 685 (mean per patient-month).

Conclusion: In our pilot report, the RPM system allowed the accurate assessment of daily APD sessions to suggest significative organizational and economic advantages, and both patients and healthcare providers reported good subjective experiences in terms of safety and quality of follow-up.

Evaluating a remote patient monitoring program for automated peritoneal dialysis

Source: Peritoneal Dialysis International

Background: The benefits of automated peritoneal dialysis (APD) have been established, but patient adherence to treatment remains a concern. Remote patient monitoring (RPM) programs are a potential solution; however, the cost implications are not well established. This study modeled, from the payer perspective, expected net costs and clinical consequences of a novel RPM program in Colombia.

Methods: Amarkov model was used to project costs and clinical outcomes for APD patients with and without RPM. Clinical inputs were directly estimated from Renal Care Services data or taken from the literature. Dialysis costs were estimated from national fees. Inpatient costs were obtained from a recent Colombian study. The model projected overall direct costs and several clinical outcomes. Deterministic and probabilistic sensitivity analyses (DSA and PSA) were also conducted to characterize uncertainty in the results.

Results: The model projected that the implementation of an RPM program costing US$35 per month in a cohort of 100 APD patients over 1 year would save US$121,233. The model also projected 31 additional months free of complications, 27 fewer hospitalizations, 518 fewer hospitalization days, and 6 fewer peritonitis episodes. In the DSA, results were most sensitive to hospitalization rates and days of hospitalization, but cost savings were robust. The PSA found there was a 91% chance for the RPM program to be cost saving.

Conclusion: The results of the model suggest that RPM is cost-effective in APD patients which should be verified by a rigorous prospective cost analysis.

The impact of a remote monitoring system of healthcare resource consumption in patients on automated peritoneal dialysis (APD): A simulation study

Source: Clinical Nephrology

Aims: Remote monitoring (RM) can improve management of chronic diseases. We evaluated the impact of RM in automated peritoneal dialysis (APD) in a simulation study.

Materials and methods: We simulated 12 patient scenarios with common clinical problems and estimated the likely healthcare resource consumption with and without the availability of RM (RM+ and RM- groups, respectively). Scenarios were evaluated 4 times by randomly allocated nephrologist-nurse teams or nephrologist-alone assessors.

Results: The RM+ group was assessed as having significantly lower total healthcare resource consumption compared with the RM- group (36.8 vs. 107.5 total episodes of resource consumption, p = 0.002). The RM+ group showed significantly lower "unplanned hospital visits" (2.3 vs. 11.3, p = 0.005), "emergency room visits" (0.5 vs. 5.3, p = 0.003), "home visits" (0.5 vs. 5.8, p = 0.016), "exchanges over the telephone" (18.5 vs. 57.8, p = 0.002), and "change to hemodialysis" (0.5 vs. 2.5, p = 0.003). Evaluations did not differ between nephrologist-nurse teams vs. nephrologist-alone assessors.

Conclusion: RM can be expected to reduce healthcare resource consumption in APD patients.

Remote Monitoring of Automated Peritoneal Dialysis Improves Personalization of Dialytic Prescription and Patient's Independence

Source: Blood Purification

Background: Remote monitoring (RM) supports a healthcare model that enhances patients' self-management. We evaluated the utility of RM in patients undergoing automated peritoneal dialysis (APD).

Methods: We observed 37 -RM-APD patients, 16 incidents, and 21 prevalents switched from traditional APD (T-APD). We observed the number of changes for APD prescription, the frequency of visits, and PD adequacy parameters during 1 year of RM utilization in APD.

Results: The APD prescriptions were modified more frequently in RM-APD vs. T-APD in incident (p = 0.002) and prevalent patients (p = 0.045). Visits were significant less in -RM-APD than in T-APD for incident patient (p = 0.008). No significant difference was found between prevalent populations. PD adequacy was similar in both groups.

Conclusions: Our results demonstrate that RM allows an efficient use of healthcare resources, helping to improve personalization of APD prescription and to intervene early with "trouble shooting", thereby reducing the frequency of in-person visits for emergency problems.

Longitudinal Experience with Remote Monitoring for Automated Peritoneal Dialysis Patients

Source: Nephron

Background: Peritoneal dialysis (PD) is an ideal model for testing remote monitoring (RM). In this study, we evaluated the RM application longitudinally in stable patients undergoing automated PD (APD).

Methods: This was an observational study, comparing outcomes in patients with (current patients) and without (historical data) exposure of RM. We analyzed cost-effectiveness of RM-APD measuring the number of night alarms, number of hospital visits, direct and indirect costs.

Results: Changes in APD prescription were almost double in the case group (RM) compared to the control group (p = 0.0005). The need for in-person visits and nocturnal alarms was significantly less in RM-APD than in traditional APD (p = 0.01 and p = 0.002, respectively). The distance traveled by patients in the case of RM-APD was reduced by 1,134 km with a time saving of 1,554 min for patients. The overall cost reduction for the PD center in terms of time/nurse and time/physician was 2,647 and 3,673 min, respectively. All these advantages were obtained in the presence of an improved technique survival with a significant reduction of dropouts. All patients found that it is easy to use the RM system and were satisfied with the high level of interaction with the care team and with the possibility of timely resolving technical problems.

Conclusion: These data confirm the long-term benefits of RM applied to APD. RM-APD is cost-effective; it allows early detection and resolution of problems, improved treatment compliance, reduction of patient's access to hospital center for technical and clinical complications with consequent savings, and improved patient's quality of life.

Telehealth Intervention Programs for Seniors: An Observational Study of a Community-Embedded Health Monitoring Initiative

Source: Telemedicine Journal and e-Health

Background: Chronic disease in older adults is estimated to account for 84% of annual health care spending in the United States, with many preventable costs expected to rise as the population continues to age.

Introduction: Telehealth Intervention Programs for Seniors (TIPS) is a community-embedded program targeting low-income older adults, providing weekly assessment of vital signs and subjective wellness, and wrap-around aging services.

Materials and Methods: TIPS recruited 765 volunteers over 55 years, who were Medicaid and/or Medicare eligible. Data were collected from 2014 to 2016 [median enrollment 343 days (105-435)] using 12 TIPS sites. This observational study evaluated the efficacy of TIPS by measuring within-subject changes in self-reported hospital visits and <30-day readmissions, before and during TIPS participation. Data of 617 participants (median age 74.3; interquartile range 16) were analyzed.

Results: Self-reported hospital visits were reduced by 28.9% (p = 0.0013). Medicare participants benefited the most, with a 50% (p < 0.0001) reduction in hospital visits, and a 75.5% (p = 0.017) reduction in <30-day readmissions. Multivariate analysis revealed that participants (1) Medicaid-registered (odds ratio [OR] = 2.72, 95% confidence interval [CI] 0.392-1.611), (2) reporting feeling unwell (OR = 1.33, 95% CI 0.118-0.459), and (3) living alone (OR = 2.34, 95% CI 0.115-1.592) were significantly more likely than other participants to experience a hospital visit.

Discussion: TIPS demonstrates that community-embedded health services can reduce rates of hospital visits in older adults.

Conclusion: The success of TIPS highlights the potential of successfully deployed remote patient-monitoring initiatives in reducing the utilization of costly health services.
