The follow-up of renal transplant recipients by telephone consultation: three years experience from a single UK renal unit

The potential of virtual healthcare technologies to reduce healthcare services' carbon footprint

The COVID-19 pandemic demonstrated the potential to reduce our carbon footprint especially by reducing travel. We aim to describe healthcare and health education services' contribution to the global climate emergency and identify the need for increased use of virtual health service delivery and undergraduate/postgraduate education to help reduce the impact of health service and health education delivery on the environment. Health care services, as one of the largest contributors to carbon emissions, must take steps to rapidly reduce their carbon footprint. Health services have unfortunately paid little attention to this issue until recently. Virtual healthcare and education have a valuable role in transition to a net carbon-zero outcome. Given the increasing use of and satisfaction with virtual health services such as telehealth, and the increase in virtual education opportunities, it is important that a concerted effort is undertaken to increase their use across health services and education in the future.

Telemedicine for Kidney Transplant Recipients: Current State, Advantages, and Barriers

Telemedicine is defined as the use of electronic information and communication technologies to provide and support healthcare at a distance. In kidney transplantation, telemedicine is limited but is expected to grow markedly in the coming y. Current experience shows that it is possible to provide transplant care at a distance, with benefits for patients like reduced travel time and costs, better adherence to medication and appointment visits, more self-sufficiency, and more reliable blood pressure values. However, multiple barriers in different areas need to be overcome for successful implementation, such as recipients' preferences, willingness, skills, and digital literacy. Moreover, in many countries, limited digital infrastructure, legislation, local policy, costs, and reimbursement issues could be barriers to the implementation of telemedicine. Finally, telemedicine changes the way transplant professionals provide care, and this transition needs time, training, willingness, and acceptance. This review discusses the current state and benefits of telemedicine in kidney transplantation, with the aforementioned barriers, and provides an overview of future directions on telemedicine in kidney transplantation.

Early referring saved lives in kidney transplant recipients with COVID-19: a beneficial role of telemedicine

Introduction

There is a strong impetus for the use of telemedicine for boosting early detection rates and enabling early treatment and remote monitoring of COVID-19 cases, particularly in chronically ill patients such as kidney transplant recipients (KTRs). However, data regarding the effectiveness of this practice are lacking.

Methods

In this retrospective, observational study with prospective data gathering we analyzed the outcomes of all confirmed COVID-19 cases (n = 955) in KTRs followed at our center between March 1, 2020, and April 30, 2022. Risk factors of COVID-19 related mortality were analyzed with focus on the role of early referral to the transplant center, which enabled early initiation of treatment and remote outpatient management. This proactive approach was dependent on the establishment and use of a telemedicine system, which facilitated patient-physician communication and expedited diagnostics and treatment. The main exposure evaluated was early referral of KTRs to the transplantation center after confirmed or suspected COVID-19 infection. The primary outcome was the association of early referral to the transplantation center with the risk of death within 30 days following a COVID-19 diagnosis, evaluated by logistic regression.

Results

We found that KTRs who referred their illness to the transplant center late had a higher 30-day mortality (4.5 vs. 13.6%, p < 0.001). Thirty days mortality after the diagnosis of COVID-19 was independently associated with late referral to the transplant center (OR 2.08, 95% CI 1.08-3.98, p = 0.027), higher age (OR 1.09, 95% CI 1.05-1.13, p < 0.001), higher body mass index (OR 1.06, 95% CI 1.01-1.12, p = 0.03), and lower eGFR (OR 0.96, 95% CI 0.94-0.98, p < 0.001) in multivariable logistic regression. Furthermore, KTRs who contacted the transplant center late were older, had longer time from transplantation, lived farther from the center and presented with higher Charlson comorbidity index.

Discussion

A well-organized telemedicine program can help to protect KTRs during an infectious disease outbreak by facilitating pro-active management and close surveillance. Furthermore, these results can be likely extrapolated to other vulnerable populations, such as patients with chronic kidney disease, diabetes or autoimmune diseases requiring the use of immunosuppression.

The role of virtual consulting in developing environmentally sustainable healthcare: a systematic literature review (Preprint)

BACKGROUND

Health systems globally need to rapidly set and achieve targets for reaching net zero carbon emissions. Virtual consulting (including video- and telephone-based consulting) is regarded as one means by which this might be achieved, largely through reduced patient travel. Little is currently known about the ways in which forms of virtual consulting might contribute to the net zero agenda or how countries may develop and implement programs at scale that can support increased environmental sustainability.

OBJECTIVE

In this paper, we asked, What is the impact of virtual consulting on environmental sustainability in health care? and What can we learn from current evaluations that can inform future reductions in carbon emissions?

METHODS

We conducted a systematic review of published literature according to PRISMA (Preferred Reporting Item for Systematic Reviews and Meta-Analyses) guidelines. We searched the MEDLINE, PubMed, and Scopus databases using key terms relating to "carbon footprint," "environmental impact," "telemedicine," and "remote consulting," using citation tracking to identify additional articles. The articles were screened, and full texts that met the inclusion criteria were obtained. Data on the approach to carbon footprinting reported reductions in emissions, and the opportunities and challenges associated with the environmental sustainability of virtual consultations were extracted into a spreadsheet, analyzed thematically, and theorized using the Planning and Evaluating Remote Consultation Services framework to consider the various interacting influences, including environmental sustainability, that shape the adoption of virtual consulting services.

RESULTS

A total of 1672 papers were identified. After removing duplicates and screening for eligibility, 23 papers that focused on a range of virtual consulting equipment and platforms across different clinical conditions and services were included. The focus on the environmental sustainability potential of virtual consulting was unanimously reported through carbon savings achieved by a reduction in travel related to face-to-face appointments. The shortlisted papers used a range of methods and assumptions to determine carbon savings, reporting these using different units and across varied sample sizes. This limited the potential for comparison. Despite methodological inconsistencies, all papers concluded that virtual consulting significantly reduced carbon emissions. However, there was limited consideration of wider factors (eg, patient suitability, clinical indication, and organizational infrastructure) influencing the adoption, use, and spread of virtual consultations and the carbon footprint of the entire clinical pathway in which the virtual consultation was provided (eg, risk of missed diagnoses from virtual consultations that result in the need for subsequent in-person consultations or admissions).

CONCLUSIONS

There is overwhelming evidence that virtual consulting can reduce health care carbon emissions, largely through reducing travel related to in-person appointments. However, the current evidence fails to look at system factors associated with implementing virtual health care delivery and wider research into carbon emissions across the entire clinical pathway.

A Transparency Checklist for Carbon Footprint Calculations Applied within a Systematic Review of Virtual Care Interventions

Increasing concerns about climate change imply that decisions on the digitization of healthcare should consider evidence about its carbon footprint (CF). This study aims to develop a transparency catalogue for reporting CF calculations, to compare results, and to assess the transparency (reporting quality) of the current evidence of virtual care (VC) intervention. We developed a checklist of transparency criteria based on the consolidation of three established standards/norms for CF calculation. We conducted a systematic review of primary studies written in English or German on the CF of VC interventions to check applicability. Based on our checklist, we extracted methodological information. We compared the results and calculated a transparency score. The checklist comprises 22 items in the aim, scope, data and analysis categories. Twenty-three studies out of 1466 records were included, mostly addressing telemedicine. The mean transparency score was 38% (minimum 14%, maximum 68%). On average, 148 kg carbon dioxide equivalents per patient were saved. Digitization may have co-benefits, improving care and reducing the healthcare CF. However, the evidence for this is weak, and CF reports are heterogeneous. Our transparency checklist may serve as a reference for developing a standard to assess the CF of virtual and other healthcare and public health services.

Greenhouse Gas Emission Savings in Relation to Telemedicine and Associated Patient Benefits: A Systematic Review

Introduction: Telemedicine is a rapidly expanding service in the digitization of health care systems. Recently emphasis has been placed on the decarbonization of health care systems with National and World Health Organization initiatives aimed at carbon neutrality toward the mid-21st century. This study investigates greenhouse gas emissions related to telemedicine, its potential role in achieving carbon neutrality and its role in determining policy. We further investigate patient benefits related to telemedicine. Methods: A systematic review was conducted of the PubMed, Medline, EMBASE, EMCARE, CINAHL, and HMIC databases. Eligibility of studies was determined by predefined criteria. Results: A total of 31 studies were identified totaling over 57,000 patients. Carbon savings ranged from 0.69 kg CO2e (carbon dioxide equivalent) to 893 kg CO2e per encounter. Distances saved also ranged from 6.1 to 3,386 km. Further analysis of 18 included studies was conducted for cost savings that ranged from €1.73 in fuel costs to over U.S. $900 in travel related expenses. Similarly, 15 included studies were analyzed for time savings, which ranged from 38 min to 24 h. Conclusions: There are substantial carbon savings to be made with telemedicine systems. Furthermore, there are substantial benefits to patients in terms of both time savings and cost savings. Rural and isolated communities or patients needing tertiary or quaternary care may be a particular cohort that might benefit disproportionally from telemedicine and is an area where the largest per capita emission savings can potentially be made.

Enhancing clinical judgement in virtual care for complex chronic disease

The COVID-19 pandemic has transformed traditional in-person care into a new reality of virtual care for patients with complex chronic disease (CCD), but how has this transformation impacted clinical judgement? I argue that virtual specialist-patient interaction challenges clinical reasoning and clinical judgement (clinical reasoning combined with statistical reasoning). However, clinical reasoning can improve by recognising the abductive, deductive, and inductive methods that the clinician employs. Abductive reasoning leading to an inference to the best explanation or invention of an explanatory hypothesis is the default response to unfamiliar or confusing situations. Deductive reasoning supports a previously established goal, but deductive accuracy requires sound premises leading to a valid conclusion. Inductive reasoning uses efficient data sorting, data interpretation, and plan creation without a previously established goal, and allows assessing inferential accuracy over time. In all cases, communication remains the backbone of the clinical encounter. Virtual care for CCD challenges clinical judgement by reducing available information, so even experienced specialists who use induction might default to deduction or abduction. The visit might shorten, decreasing narrative competence and in-turn management quality. Clinical judgement in virtual encounters can be enhanced by allowing sufficient time, employing allied health staff, using an advance script, avoiding dogmatic commitment to either virtual or in-person encounters, special training in virtual care, and conscious awareness of abductive, deductive, and inductive reasoning processes. Clinical judgement in virtual encounters especially calls for Gestalt cognition to assess a situational pattern irreducible to its parts and independent of its particulars, so that efficient data interpretation and self-reflection are enabled. Gestalt cognition integrates abduction, deduction, and induction, appropriately divides the time and effort spent on each, and can compensate for reduced available information. Evaluating one's clinical judgement for those components especially vulnerable to compromise can help optimize the delivery of virtual care for patients with CCD.

Clinical outcomes of a nurse-led post-discharge education program for heart-transplant recipients: A retrospective cohort study

BACKGROUND

Advances in immunosuppressive therapeutics and medical technology have improved survival rates after heart transplantation. Although there is a rigorous schedule of outpatient visits and testing to detect early signs of rejection and other complications in the first year after transplantation, repeated unplanned readmissions of heart transplant recipients remains a challenge.

OBJECTIVE

This study aimed to compare the effects of specialized nurse-led discharge education, including continuous post-transplant education and counselling, on heart transplant recipients' clinical outcomes, with the effects of existing discharge education.

METHODS

Participants were 136 heart transplantation recipients at a university-affiliated hospital in South Korea from November 1, 1994, to November 30, 2018. Participants' electronic medical records were retrospectively analyzed. Participants were grouped according to usual care (n = 25), nurse-led program (n = 66), and nurse-led program with post-discharge education (n = 45). We assessed the number of outpatient visits with clinical problems and days to first unplanned rehospitalization within one year after transplantation.

RESULTS

The nurse-led program with post-discharge education was associated with significantly reduced outpatient visits with clinical problems, compared to usual care and the existing nurse-led program. We also found a significantly longer time until first unplanned rehospitalization in the nurse-led program with post-discharge education group, compared to the usual care group.

CONCLUSION

This study identified the heart transplantation-specialized nurse-led discharge and subsequent post-discharge education as an effective strategy for positive clinical outcomes within one year after heart transplantation.

Does telemedicine reduce the carbon footprint of healthcare? A systematic review

In the rapidly progressing field of telemedicine, there is a multitude of evidence assessing the effectiveness and financial costs of telemedicine projects; however, there is very little assessing the environmental impact despite the increasing threat of the climate emergency. This report provides a systematic review of the evidence on the carbon footprint of telemedicine. The identified papers unanimously report that telemedicine does reduce the carbon footprint of healthcare, primarily by reduction in transport-associated emissions. The carbon footprint savings range between 0.70-372 kg CO₂e per consultation. However, these values are highly context specific. The carbon emissions produced from the use of the telemedicine systems themselves were found to be very low in comparison to emissions saved from travel reductions. This could have wide implications in reducing the carbon footprint of healthcare services globally. In order for telemedicine services to be successfully implemented, further research is necessary to determine context-specific considerations and potential rebound effects.

Opportunities in the cloud or pie in the sky? Current status and future perspectives of telemedicine in nephrology

The use of telehealth to support, enhance or substitute traditional methods of delivering healthcare is becoming increasingly common in many specialties, such as stroke care, radiology and oncology. There is reason to believe that this approach remains underutilized within nephrology, which is somewhat surprising given the fact that nephrologists have always driven technological change in developing dialysis technology. Despite the obvious benefits that telehealth may provide, robust evidence remains lacking and many of the studies are anecdotal, limited to small numbers or without conclusive proof of benefit. More worryingly, quite a few studies report unexpected obstacles, pitfalls or patient dissatisfaction. However, with increasing global threats such as climate change and infectious disease, a change in approach to delivery of healthcare is needed. The current pandemic with coronavirus disease 2019 (COVID-19) has prompted the renal community to embrace telehealth to an unprecedented extent and at speed. In that sense the pandemic has already served as a disruptor, changed clinical practice and shown immense transformative potential. Here, we provide an update on current evidence and use of telehealth within various areas of nephrology globally, including the fields of dialysis, inpatient care, virtual consultation and patient empowerment. We also provide a brief primer on the use of artificial intelligence in this context and speculate about future implications. We also highlight legal aspects and pitfalls and discuss the 'digital divide' as a key concept that healthcare providers need to be mindful of when providing telemedicine-based approaches. Finally, we briefly discuss the immediate use of telenephrology at the onset of the COVID-19 pandemic. We hope to provide clinical nephrologists with an overview of what is currently available, as well as a glimpse into what may be expected in the future.

Projecting the Number of Posttransplant Clinic Visits With a Rise in the Number of Kidney Transplants: A Case Study From Ontario, Canada

Background:

In Ontario, kidney transplants have risen by 4% annually in recent years. An understanding of how this will affect the future annual number of posttransplant follow-up visits informs how to organize and deliver care.

Objective:

We projected the required number of annual posttransplant follow-up nephrology visits to inform posttransplant care delivery.

Design:

Population-based retrospective cohort study.

Setting:

Linked databases from Ontario, Canada (population 14 million).

Patients:

Incident kidney transplant recipients from years 2008 to 2013.

Measurements:

Frequency, distance traveled, and current and projected visits for posttransplant follow-up.

Methods:

Assuming a graft survival of 13 years and using the mean number of posttransplant clinic visits in years 1, 2, and 3, we forecasted the number of clinic visits needed in the year 2027.

Results:

Using data from 2443 recipients, the mean (SD) number of clinic visits per recipient was 14.0 (9.2) in the first year after transplant, and 3.9 (6.2) and 3.0 (5.3) in the second and third year, respectively. If transplant rates rise by 4% per year until 2027, the estimated annual visits number will increase from 30 622 to 43 948. The median (25th, 75th percentile) distance between transplant center and patient’s home was 30 (13, 65) km. The median round-trip travel distance for these visits in the first year after transplantation was 603 km per recipient, and median driving cost was Can$344 (2017).

Limitations:

Regarding patient expense, limitations include that distances traveled were calculated orthodromically, and we did not account for patient cost of follow-up beyond that of vehicular travel. Regarding follow-up projections, limitations include the assumption that graft life span will not change, follow-up patterns do not differ between donor kidney type, and we did not survey stakeholders as to their preferred method of follow-up.

Conclusion:

We quantified the increase in posttransplant visits when regional annual rates of transplantation rise. Strategies recognizing the burden of these visits may enhance patient-centered care, as it is unclear how some patients manage costs, nor how the current health care system will manage the demand.

Establishing a tele-clinic service for kidney transplant recipients through a patient-codesigned quality improvement project

Kidney transplant patients in our regional centre travel long distances to attend routine hospital follow-up appointments. Patients incur travel costs and productivity losses as well as adverse environmental impacts. A significant proportion of these patients, who may not require physical examination, could potentially be managed through telephone consultations (tele-clinic). We adopted a Quality Improvement approach with iterative Plan-Do-Study-Act (PDSA) cycles to test the introduction of a tele-clinic service. We codesigned the service with patients and developed a prototype delivery model that we then tested over two PDSA improvement ramps containing multiple PDSA cycles to embed the model into routine service delivery. Nineteen tele-clinics were held involving 168 kidney transplant patients (202 tele-consultations). 2.9% of tele-clinic patients did not attend compared with 6.9% for face-to-face appointments. Improving both blood test quality and availability for the tele-clinic was a major focus of activity during the project. Blood test quality for tele-clinics improved from 25% to 90.9%. 97.9% of survey respondents were satisfied overall with their tele-clinic, and 96.9% of the patients would recommend this to other patients. The tele-clinic saved 3527 miles of motorised travel in total. This equates to a saving of 1035 kgCO2. There were no unplanned admissions within 30 days of the tele-clinic appointment. The service provided an immediate saving of £6060 for commissioners due to reduced tele-clinic tariff negotiated locally (£30 less than face-to-face tariff). The project has shown that tele-clinics for kidney transplant patients are deliverable and well received by patients with a positive environmental impact and modest financial savings. It has the potential to be rolled out to other renal centres if a national tele-clinic tariff can be negotiated, and an integrated, appropriately reimbursed community phlebotomy system can be developed to facilitate remote monitoring of patients.

Effect of Consultation and Follow-up Phone Calls on Biochemical Indicators and Intradialytic Weight Gain in Patients Undergoing Hemodialysis

OBJECTIVES

We sought to determine the effect of consultation and follow-up phone calls on biochemical indicators and intradialytic weight gain (IWG) in patients undergoing hemodialysis.

METHODS

We conducted a double-blind, randomized clinical trial of 86 patients undergoing hemodialysis in Iran. Patients were grouped through convenience sampling and randomly allocated into two groups. The experimental group had face-to-face consultations, and each patient was given a monthly diet. Next, over 12 weeks, we conducted 28 follow-up phone calls. In both groups, biochemical indicators and IWG were measured at baseline, and in the fourth, eighth, and twelfth weeks of the study.

RESULTS

The results showed that calcium and IWG indices in the fourth, eighth, and twelfth week, and phosphorus and potassium and IWG indices in the eighth and twelfth weeks had statistically significant differences between the experimental and control groups (p < 0.050).

CONCLUSIONS

In our study, consultation and follow-up phone calls in hemodialysis patients result in improved biochemical indicators. Therefore, in patients undergoing hemodialysis, consultation and follow-up phone calls are recommended to improve patient's biochemical indicators.

Telehealth model of care for routine follow up of renal transplant recipients in a tertiary centre: A case study

Royal Melbourne Hospital (RMH) performs over 140 kidney transplant operations annually. Kidney transplant recipients require regular medical review, which results in loss of time and costs from travel, particularly for regional patients, and places high demand on the hospital outpatient service. The RMH renal transplant unit initiated a telehealth service in 2016 to provide cost effective, patient-centred clinical care for regional patients. To date, 263 clinical reviews have been conducted via telehealth, potentially saving 203,202 kilometres in travel distance; 2771 hours in car travel time; an estimated AUD $31,048 in petrol savings and 51 tonnes CO₂ equivalents of greenhouse gas emissions. Lessons learnt have included the importance of using technology that allows patients to access telehealth from their place of choice. The option of a joint consultation with local healthcare providers has facilitated the development of extended care networks for our patients. Incorporation of telehealth into our outpatient system has been achieved with the existing nephrology workforce, making it a sustainable long-term review option. Our renal transplant telehealth outpatient clinic has been a successful change in the way we provide care to regional patients. Formal comparison of clinical outcomes and the patient experience of telehealth versus in person reviews are underway.

Evaluating the impact of a 'virtual clinic' on patient experience, personal and provider costs of care in urinary incontinence: A randomised controlled trial

OBJECTIVE

To evaluate the impact of using a 'virtual clinic' on patient experience and cost in the care of women with urinary incontinence.

MATERIALS AND METHODS

Women, aged > 18 years referred to a urogynaecology unit were randomised to either (1) A Standard Clinic or (2) A Virtual Clinic. Both groups completed a validated, web-based interactive, patient-reported outome measure (ePAQ-Pelvic Floor), in advance of their appointment followed by either a telephone consultation (Virtual Clinic) or face-to-face consultation (Standard Care). The primary outcome was the mean 'short-term outcome scale' score on the Patient Experience Questionnaire (PEQ). Secondary Outcome Measures included the other domains of the PEQ (Communications, Emotions and Barriers), Client Satisfaction Questionnaire (CSQ), Short-Form 12 (SF-12), personal, societal and NHS costs.

RESULTS

195 women were randomised: 98 received the intervention and 97 received standard care. The primary outcome showed a non-significant difference between the two study arms. No significant differences were also observed on the CSQ and SF-12. However, the intervention group showed significantly higher PEQ domain scores for Communications, Emotions and Barriers (including following adjustment for age and parity). Whilst standard care was overall more cost-effective, this was minimal (£38.04). The virtual clinic also significantly reduced consultation time (10.94 minutes, compared with a mean duration of 25.9 minutes respectively) and consultation costs compared to usual care (£31.75 versus £72.17 respectively), thus presenting potential cost-savings in out-patient management.

CONCLUSIONS

The virtual clinical had no impact on the short-term dimension of the PEQ and overall was not as cost-effective as standard care, due to greater clinic re-attendances in this group. In the virtual clinic group, consultation times were briefer, communication experience was enhanced and personal costs lower. For medical conditions of a sensitive or intimate nature, a virtual clinic has potential to support patients to communicate with health professionals about their condition.

Self-management and self-efficacy status in liver recipients

BACKGROUND

Liver transplantation (LT) is a viable treatment for patients with end-stage chronic liver diseases. The main aim of LT is to prolong life and improve life quality. However, although survival after LT continues to improve, some aspects of recipient's health-related quality of life such as self-management and self-efficacy have been largely ignored.

METHODS

A total of 124 LT recipients were included in this study. Questionnaires for general health status information and a "Self-Management Questionnaire for Liver Transplantation Recipients" modified from the Chinese version of "Chronic Disease Self-Management Program Questionnaire Code Book" were used in the survey. Data were collected by self-administered questionnaires.

RESULTS

The overall status of self-management in LT recipients was not optimistic. The major variables affecting the self-management of LT recipients were marital status, educational level and employment. The overall status of self-efficacy in LT recipients was around the medium-level. Postoperative time and self-assessment of overall health status were found as the factors impacting on self-efficacy.

CONCLUSIONS

The self-management behavior of LT recipients needs to be improved. The health care professionals need to offer targeted health education to individual patients, help them to establish healthy lifestyle, enhance physical activity and improve self-efficacy. The development of the multilevel and multifaceted social support system will greatly facilitate the self-management in LT patients.

Reducing the carbon footprint of hospital-based care

Climate change, driven by man-made greenhouse gas emissions, is a major threat to the health of this and future generations. Hospital-based healthcare generates large quantities of greenhouse gas emissions. Reducing the carbon footprint of healthcare requires direct action to reduce waste and energy use, but also requires radical reform of care pathways so that the only patients who come to or stay in hospital are people whose healthcare cannot safely be delivered closer to home. Achieving these reforms without major structural changes to the financial flows in the NHS will be extraordinarily difficult.
