Carbon Footprint of Telemedicine Solutions - Unexplored Opportunity for Reducing Carbon Emissions in the Health Sector

Background

The healthcare sector is a significant contributor to global carbon emissions, in part due to extensive travelling by patients and health workers.

Objectives

To evaluate the potential of telemedicine services based on videoconferencing technology to reduce travelling and thus carbon emissions in the healthcare sector.

Methods

A life cycle inventory was performed to evaluate the carbon reduction potential of telemedicine activities beyond a reduction in travel related emissions. The study included two rehabilitation units at Umeå University Hospital in Sweden. Carbon emissions generated during telemedicine appointments were compared with care-as-usual scenarios. Upper and lower bound emissions scenarios were created based on different teleconferencing solutions and thresholds for when telemedicine becomes favorable were estimated. Sensitivity analyses were performed to pinpoint the most important contributors to emissions for different set-ups and use cases.

Results

Replacing physical visits with telemedicine appointments resulted in a significant 40–70 times decrease in carbon emissions. Factors such as meeting duration, bandwidth and use rates influence emissions to various extents. According to the lower bound scenario, telemedicine becomes a greener choice at a distance of a few kilometers when the alternative is transport by car.

Conclusions

Telemedicine is a potent carbon reduction strategy in the health sector. But to contribute significantly to climate change mitigation, a paradigm shift might be required where telemedicine is regarded as an essential component of ordinary health care activities and not only considered to be a service to the few who lack access to care due to geography, isolation or other constraints.     

Setting standards based on patients' views on access and continuity: secondary analysis of data from the general practice assessment survey

ObjectivesTo examine patients'' views on access and continuity in general practice to derive quality standards.DesignSecondary analysis of data from general practice research studies and routine quality assessment activities undertaken by practices and primary care trusts.SettingGeneral practice.ParticipantsGeneral practice patients.ResultsSatisfactory standards of access were next day appointments with general practitioners and a 6-10 minute wait for consultations to begin. A satisfactory level of continuity was seeing the same general practitioner “a lot of the time.” Standards varied with the analytic method used and by sociodemographic group.ConclusionsStandards expected by patients in primary care can be derived from linked report-assessment pairs. Patients may have expectations of access that are in excess of government targets. Patients also have high expectations of continuity of care. It is unclear the degree to which such standards are reliable or valid, how conflicts between access and continuity should be resolved, or how these standards relate to other priorities of patients such as high quality interpersonal care.

What is already known on this topic

Standards are increasingly being set for the provision of health servicesSurveys and consultation exercises before the NHS plan helped set the standard for a maximum waiting time of 48 hours for appointments to see general practitionersThe optimal methods by which patients should be involved in setting standards and the utility of such standards are unclear

What this study adds

Satisfactory standards of access were next day appointments, a 6-10 minute wait for consultations to begin, and seeing the same general practitioner a lot of the timePatients may have expectations for access to primary care in excess of current government targets     

A study of patients attending without appointments in an urban general practice.

OBJECTIVE--To ascertain which social and psychological characteristics are associated with patients attending surgeries without appointments. DESIGN--Prospective study of patients attending an urban centre group practice. SETTING--Urban health centre group practice with five doctors and 12,000 patients in an area of high (greater than 20%) unemployment and social deprivation. PATIENTS--All attenders at the open access surgery and one in four consecutive attenders by appointment, selected sequentially from the first three appointments, during 10 days in January 1989. Patients participating in the pilot study, reattending during the study period, or attending antenatal clinics were excluded. MAIN OUTCOME MEASURES--Patients'' attitude to making appointments and reasons for attending, including perception of urgency, with respect to sociodemographic and psychosocial data obtained from a self completed questionnaire before the consultation. Doctors'' diagnosis and perception of urgency obtained from a separate questionnaire. RESULTS--86% (141/172) Of patients attending without appointments and 96% (139/145) with appointments responded to the questionnaire. The need for consultation was considered to be "very urgent" or "fairly urgent" in significantly more of the open access group than the appointments group (89%, 124/139 v 66%, 91/138; chi 2 = 27.04, df = 3; p less than 0.001), although the doctors did not share the same views. Significantly more patients had self limiting conditions of recent onset in the open access than in the appointments group (75%, 101/135 v 48%, 59/123: p less than 0.001). Overall, open access attendance was significantly linked with social support (39%, 48/124 v 26%, 32/123; p less than 0.05) and with marital separations or intentions to separate (10%, 9/87 v 0/92; 47%, 32/87 v 22%, 20/92 respectively; both p less than 0.001), but the doctors recorded significantly fewer psychological and social problems in these patients (p less than 0.05). Although almost half those in the appointments group considered that making appointments was inconvenient, more of those in the open access group agreed with this view (47%, 60/129 v 61%, 80/131). CONCLUSIONS--There was an important link between social support problems and a negative attitude to making appointments. In our previous experience encouraging patients to make appointments has been unsuccessful; practices serving areas with a high prevalence of social deprivation providing a mixed open access and appointments system may better serve patients'' needs.     

Impact of High Deductible Health Plans on Diabetes Care Quality and Outcomes: Systematic Review

ObjectiveTo provide a review of the impact of high deductible health plans (HDHPs) on the utilizations of services required for optimal management of diabetes and subsequent health outcomes.MethodsSystematic literature review of studies published between January 1, 2000, and May 7, 2021, was conducted that examined the impact of HDHP on diabetes monitoring (eg, recommended laboratory and surveillance testing), routine care (eg, ambulatory appointments), medication management (eg, medication initiation, adherence), and acute health care utilization (eg, emergency department visits, hospitalizations, incident complications).ResultsOf the 303 reviewed articles, 8 were relevant. These studies demonstrated that HDHPs lower spending at the expense of reduced high-value diabetes monitoring, routine care, and medication adherence, potentially contributing to the observed increases in acute health care utilization. Additionally, patient out-of-pocket costs for recommended screenings doubled, and total health care expenditures increased by 49.4% for HDHP enrollees compared with enrollees in traditional health plans. Reductions in disease monitoring and routine care and increases in acute health care utilization were greatest in lower-income patients. None of the studies examined the impact of HDHPs on access to diabetes self-management education, technology use, or glycemic control.ConclusionAlthough HDHPs reduce some health care utilization and costs, they appear to do so at the expense of limiting high-value care and medication adherence. Policymakers, providers, and payers should be more cognizant of the potential for negative consequences of HDHPs on patients’ health.     

Improving Ambulatory Diabetes Care In High-Risk Racial Minorities:Use Of Culture-Specific Education And Close Follow-Up

ObjectiveTo describe a project aimed at improving diabetes care in the ambulatory setting among 2 high-risk racial minorities (African American and Hispanic patients) by using culture-specific education provided by trained diabetes educators from the same racial groups as the targeted patients.MethodsTwo nurse educators, 1 Hispanic and 1 African American, completed a standardized chronic disease management program, as did 2 patients with diabetes from each of the aforementioned ethnic groups in preparation for training other patients. The study patients participated in group classes or one-on-one sessions to learn about appropriate management of their diabetes, related complications, and improved lifestyle habits. Close follow-up by telephone and regular appointments ensured that appropriate glucose monitoring and laboratory tests were performed. Outcome measures before and after the intervention were recorded, with final project follow-up at 24 months. A control group was identified during the same period, which received standard care (follow-up with a physician every 3 to 6 months).ResultsAn improvement in control of diabetes occurred, as determined by a significant decline in hemoglobin A1c levels in both minority study groups. Emergency department visits also decreased significantly.Lipid profiles and microalbumin showed improvement as well. More than 90% of patients kept appointments and had all laboratory studies performed.Conclusion: The project intervention had a notable effect, physically and psychologically, on the 2 ethnic sample populations studied. These results have major implications, both clinically and financially, for public health policy planning for diabetes care in minority populations. (Endocr Pract 2010;16:171-177)     

Patient initiated outpatient follow up in rheumatoid arthritis: six year randomised controlled trial

Objectives To determine whether direct access to hospital review initiated by patients with rheumatoid arthritis would result in improved clinical and psychological outcome, reduced overall use of healthcare resources, and greater satisfaction with care than seen in patients receiving regular review initiated by a rheumatologist.Design Two year randomised controlled trial extended to six years.Setting Rheumatology outpatient department in teaching hospital.Participants 209 consecutive patients with rheumatoid arthritis for over two years; 68 (65%) in the direct access group and 52 (50%) in the control group completed the study (P = 0.04).Main outcome measures Clinical outcome: pain, disease activity, early morning stiffness, inflammatory indices, disability, grip strength, range of movement in joints, and bone erosion. Psychological status: anxiety, depression, helplessness, self efficacy, satisfaction, and confidence in the system. Number of visits to hospital physician and general practitioner for arthritis.Results Participants were well matched at baseline. After six years there was only one significant difference between the two groups for the 14 clinical outcomes measured (deterioration in range of movement in elbow was less in direct access patients). There were no significant differences between groups for median change in psychological status. Satisfaction and confidence in the system were significantly higher in the direct access group at two, four, and six years: confidence 9.8 v 8.4, 9.4 v 8.0, 8.7 v 6.9; satisfaction 9.3 v 8.3, 9.3 v 7.7, 8.9 v 7.1 (all P < 0.02). Patients in the direct access group had 38% fewer hospital appointments (median 8 v 13, P < 0.0001).Conclusions Over six years, patients with rheumatoid arthritis who initiated their reviews through direct access were clinically and psychologically at least as well as patients having traditional reviews initiated by a physician. They requested fewer appointments, found direct access more acceptable, and had more than a third fewer medical appointments. This radical responsive management could be tested in other chronic diseases.     

Has Metal-On-Metal Resurfacing Been a Cost-Effective Intervention for Health Care Providers?—A Registry Based Study

BackgroundTotal hip replacement for end stage arthritis of the hip is currently the most common elective surgical procedure. In 2007 about 7.5% of UK implants were metal-on-metal joint resurfacing (MoM RS) procedures. Due to poor revision performance and concerns about metal debris, the use of RS had declined by 2012 to about a 1% share of UK hip procedures. This study estimated the lifetime cost-effectiveness of metal-on-metal resurfacing (RS) procedures versus commonly employed total hip replacement (THR) methods.Conclusion/SignificanceOur results imply that in most cases RS has not been a cost-effective resource and should probably not be adopted by decision makers concerned with the cost effectiveness of hip replacement, or by patients concerned about the likelihood of revision, regardless of patient age or gender.     

COVID-RO study: the radiation oncology practice at times of COVID-19 outbreak — international survey

BackgroundRadiation therapy (RT), an essential treatment of cancer, involves multiple hospital visits. We hypothesized that radiation departments would adjust their work patterns and RT protocols in response to the SARS-CoV-2 pandemic.Materials and methodsAn electronic survey was sent during April 2020 to an international sample of radiation oncologists. The survey explored various aspects of departmental preparedness, and changes to their institutional RT protocols.ResultsA total of 68 radiation oncologists from 13 countries answered the survey. Healthcare systems were at least moderately affected in 76%. Most institutes appeared well prepared for the outbreak: regarding the availability of personal protective equipment, tests, and telemedicine/videoconference facilities. Screening for SARS-CoV-2 was applied in 59% of responders. Modification of RT protocols were minor in 66%, significant in 19% and no changes made in 15%. The extent to which protocols were modified correlated with overall healthcare disruption (p = 0.028). Normal fractionation was recommended to continue in 83% and 85% of head & neck, and cervical cancers vs. 64% of lung cancers (p = 0.001).In case the pandemic worsens, there was strong agreement to prioritize RT for aggressive cancers (80%), delay RT for slow-growing tumors (78%) and change to evidance-based hypofractionations protocols (79.4%). The option of delayed/omitted adjuvant RT (not site specific) was selected in 47%.ConclusionThis international survey concludes that, by making significant organizational adjustments and minor protocol modifications, RT may be safely continued during this pandemic. If the crisis worsens, there was strong agreement to continue the treatment of aggressive tumors and utilize evidence-based hypofractionated protocols.     

Characterising the nationwide burden and predictors of unkept outpatient appointments in the National Health Service in England: A cohort study using a machine learning approach

BackgroundUnkept outpatient hospital appointments cost the National Health Service £1 billion each year. Given the associated costs and morbidity of unkept appointments, this is an issue requiring urgent attention. We aimed to determine rates of unkept outpatient clinic appointments across hospital trusts in the England. In addition, we aimed to examine the predictors of unkept outpatient clinic appointments across specialties at Imperial College Healthcare NHS Trust (ICHT). Our final aim was to train machine learning models to determine the effectiveness of a potential intervention in reducing unkept appointments.Methods and findingsUK Hospital Episode Statistics outpatient data from 2016 to 2018 were used for this study. Machine learning models were trained to determine predictors of unkept appointments and their relative importance. These models were gradient boosting machines. In 2017–2018 there were approximately 85 million outpatient appointments, with an unkept appointment rate of 5.7%. Within ICHT, there were almost 1 million appointments, with an unkept appointment rate of 11.2%. Hepatology had the highest rate of unkept appointments (17%), and medical oncology had the lowest (6%). The most important predictors of unkept appointments included the recency (25%) and frequency (13%) of previous unkept appointments and age at appointment (10%). A sensitivity of 0.287 was calculated overall for specialties with at least 10,000 appointments in 2016–2017 (after data cleaning). This suggests that 28.7% of patients who do miss their appointment would be successfully targeted if the top 10% least likely to attend received an intervention. As a result, an intervention targeting the top 10% of likely non-attenders, in the full population of patients, would be able to capture 28.7% of unkept appointments if successful. Study limitations include that some unkept appointments may have been missed from the analysis because recording of unkept appointments is not mandatory in England. Furthermore, results here are based on a single trust in England, hence may not be generalisable to other locations.ConclusionsUnkept appointments remain an ongoing concern for healthcare systems internationally. Using machine learning, we can identify those most likely to miss their appointment and implement more targeted interventions to reduce unkept appointment rates.

Combined Surgical Approach to Young Adults with Hip Dysplasia and Concomitant Intra-Articular Pathology Using Intra-Abdominal Monitoring

BackgroundCombined hip arthroscopy and periacetabular osteotomy (PAO) allows for treatment of intra-articular hip pathology with simultaneous correction of acetabular version and femoral head coverage in patients with symptomatic hip dysplasia. Currently, scant data is available to surgeons regarding optimal technique, sequence of repair, perioperative management, and the use of intra-abdominal monitoring in patients undergoing these combined procedures. The purpose of this study is to describe a two-surgeon, muscle-sparing, approach for sequential hip arthroscopy and PAO for the treatment of adults with acetabular dysplasia and concomitant intra-articular hip pathology.MethodsIn this article, we present the indications for combined hip arthroscopy and PAO, in addition to patient set-up and positioning. A detailed discussion of hip arthroscopy and a muscle sparing PAO techniques are then presented, with overview of a novel intra-abdominal pressure monitoring technique and post-operative rehabilitation protocol.ResultsThrough technical refinement and experience, our indications and protocol for the treatment of patients with symptomatic acetabular dysplasia with concomitant intra-articular hip pathology involves a refined and reproducible, two surgeon procedure utilizing hip arthroscopy followed by PAO. The use of intra-abdominal monitoring allows for assessment of intra-peritoneal pressures to monitor for the development of abdominal compartment syndrome secondary to fluid extravasation.ConclusionThe performance of concomitant hip arthroscopy and PAO for concurrent hip dysplasia and intra-articular hip pathology represents an increasingly common approach in hip preservation surgery. The hip arthroscopy and muscle-sparing PAO protocol using intra-abdominal monitoring described here serves to further refine and advance the indications and technical aspects of this challenging procedure.Level of Evidence: V     

The influence of survey frequency on population estimates of moorland breeding birds

Capsule A minimum of four constant‐effort‐search survey visits are required to generate reliable population estimates of breeding birds on moorland that are not subject to biases associated with varying levels of detectability through the season.

Aims To investigate the influence of the number and the combination of survey visits on the population estimates of breeding birds on moorland.

Methods Four constant‐effort‐search surveys (80–100 minutes per km² per visit) of moorland in southwest Scotland were undertaken in each of six years, 2003–2008. Using standard protocols, the numbers of apparent territories that would have been identified for each possible combination of survey visits were determined.glms were used to assess the influence of the frequency of survey visits, and different combination scenarios on the derived population estimates for Red Grouse, European Golden Plover, Common Snipe, Eurasian Curlew, Sky Lark, Winter Wren and Stonechat. Independent assessments of population density were made by transect sampling for Red Grouse and Sky Lark.

Results Robust population estimates were possible from three survey visits for European Golden Plover, Eurasian Curlew and Stonechat. However, there were differences between species in the seasonal variation of their detectability. Four survey visits would underestimate the populations of Red Grouse (probably by 67–91%), Sky Lark (probably by 31–61%) and Winter Wren (by an undetermined proportion). Common Snipe were also likely to be underestimated after four survey visits, but the value of the derived estimate as an index of population density deserves further investigation.

Conclusions If there is a need to carry out a multi‐species survey on moorland, we suggest that a minimum of four survey visits is required to ensure the derivation of reliable population estimates for a suite of the most readily detectable species. Population estimates derived from three or fewer survey visits risk biases through uneven sampling in periods of differing detectability. With evidence for changes in the breeding phenology of birds associated with changing climate or weather patterns, it arguably becomes more important to ensure that surveys sample an adequately broad period of the breeding season.

Development of a telemedicine program: a review of 1,000 videoconferencing consultations

Objective To examine the financial and organizational characteristics, demand for services, and satisfaction outcomes of a growing telemedicine program serving both urban or suburban and rural populations. Design Retrospective review of 1,000 consecutive telemedicine consultations in the University of California (UC) Davis Telemedicine Program. Setting Telemedicine videoconferencing units, used to integrate care in the UC Davis Health System among the UC Davis Medical Center and several urban or suburban primary care clinics, rural hospitals, and clinic affiliates. Subjects A total of 657 consecutive patients who consented to a telemedicine consultation. Main outcome measures Demographic information about the patient population, the rural and urban or suburban clinics, the types of specialty consultations, and telemedicine equipment used in the UC Davis Health System. Patient and physician satisfaction were measured on a 5-point Likert scale. Results Patients and primary care physicians reported high levels of satisfaction. Rural clinics requested more and a greater variety of specialist consultations than urban or suburban clinics. Conclusion Although referring physicians and patients indicate a high level of satisfaction with telemedicine services and insurers are negotiating reimbursement policies, additional research must investigate the reasons why some payers, patients, and providers resist participation in these services.     

Gender Differences in Questions Asked in an Online Preoperative Patient Education Program

BackgroundAlthough osteoarthritis more commonly affects women than men, women are 3 times less likely to undergo hip or knee replacement surgery compared with men. Disparity in the appropriate utilization of surgery between men and women is a complex subject that must take into account the willingness of a patient to proceed with the operation. Adequately addressing patient concerns before surgery may influence such willingness.ObjectiveWe examined if a gender difference can be identified in the frequency and types of questions submitted by patients scheduled for total hip or total knee arthroplasty.MethodsPatients completed an online interactive preoperative educational program and a database was created containing deidentified information on surgical procedure, sex, year of birth, and any questions that were submitted. Data were also available regarding the total number of patients issued the program, the number of patients who started the program, and the number of patients who completed the program. The results were analyzed by Wilcoxon rank sum test. P values ≤0.05 were considered statistically significant.ResultsAmong the 2770 women and 1708 men included in the study, 935 (34%) and 462 (27%) asked at least 1 question, respectively. Compared with men, women asked a significantly greater number of questions overall (P < 0.001). Women also asked a significantly greater number of questions in the categories Your Condition (P = 0.031), Your Procedure (P < 0.001), and Risks and Benefits (P < 0.001).ConclusionsGender differences in concerns and physicians' ability to adequately address these concerns may contribute to disparity in use of hip and knee replacement surgery between men and women. Effective preoperative counseling for women may require additional resources to address their higher level of questions.

Telehealth for Endocrinology: Experience and Effect on Utilization in the Prepandemic Era

ObjectiveTelehealth (TH) use in endocrinology was limited before the COVID-19 pandemic but will remain a major modality of care postpandemic. Reimbursement policies have been limited historically due to concerns of overutilization of visits and testing. Additionally, there is limited literature on endocrinology care delivered via TH for conditions other than diabetes. We assess real-world TH use for endocrinology in a prepandemic environment with the hypothesis that TH would not increase the utilization of total visits or related ancillary testing services compared with conventional (CVL) face-to-face office visits.MethodsA single-institution retrospective cohort study assessing the prepandemic use of TH in endocrinology, consisting of 75 patients seen via TH and 225 patients seen in CVL visits. For most patients, TH was conducted via a clinic-to-clinic model. Outcomes measured were total endocrine visit frequency and frequency of related laboratory and radiology testing per patient, hemoglobin A1C, microalbumin, low-density lipoprotein, thyroid-stimulating hormone, thyroglobulin, and thyroid ultrasounds.ResultsFor all endocrine visits, TH patients had a median of 0.24 (interquartile range, 0.015-0.36) visits per month. CVL patients had a median of 0.20 visits per month (interquartile range, 0.11-0.37). Total visits per month did not vary significantly between groups (P = .051). Hemoglobin A1C outcomes were equivalent and there was no increase in ancillary laboratory testing for the TH group.ConclusionOur observations demonstrate that, in a prepandemic health care setting, TH visits can provide equivalent care for endocrinology patients, without increasing utilization of total visits or ancillary services.     

Impact of patient-doctor race concordance on rates of weight-related counseling in visits by black and white obese individuals

The objective of this study was to assess the impact of patient-provider race concordance on weight-related counseling among visits by obese patients. We hypothesized that race concordance would be positively associated with weight-related counseling. We used clinical encounter data obtained from the 2005-2007 National Ambulatory Medical Care Surveys (NAMCS). The sample size included 2,231 visits of black and white obese individuals (ages 20 and older) to their black and white physicians from the specialties of general/family practice and general internal medicine. Three outcome measures of weight-related counseling were explored: weight reduction, diet/nutrition, and exercise. Logistic regression was used to model the outcome variables of interest. Wald tests were used to statistically compare whether physicians of each race provided counseling at different rates for obese patients of different races. We did not observe a positive association between patient-physician race concordance and weight-related counseling. We found that visits by black obese patients to white doctors had a lower odds of exercise counseling as compared to visits by white obese patients to white doctors (odds ratio (OR) = 0.54; 95% confidence interval (CI): 0.31, 0.95), and visits by black obese patients to black physicians had lower odds of receiving weight-reduction counseling than visits among white obese patients seeing black physicians (OR = 0.34; 95% CI: 0.13, 0.90). Black obese patients receive less exercise counseling than white obese patients in visits to white physicians and may be less likely than white obese patients to receive weight-reduction counseling in visits to black physicians.
