Evidence for overuse of medical services around the world

Accountability frameworks: A critical evolution in healthcare

Canadians face prolonged waits for primary care, specialist care, hospital care, elective surgery, and advanced imaging relative to peer countries. A root problem is unclear queue management expectations. If programs have no mandate to provide timely care, the intuitive approach to demand challenges is not to innovate and improve, but to block access, create a queue, and force patients elsewhere. Patient care accountability frameworks define program expectations and accountability zones, clarifying that every patient has an accountable healthcare home and every program has a population (accountability zone). Program accountabilities include timely patient assessment and disposition; budget, space, and nursing care for program patients; and contingency plans for surges and queues. Accountability frameworks are an evolutionary stressor that would drive strategies to expedite appropriate care in the right place, to move patients out of queues into care. This article discusses accountability, accountability frameworks, and accountability strategies to improve system-wide access.

Predicting abnormal C-reactive protein level for improving utilization by deep neural network model

BACKGROUND

C-reactive protein (CRP) is an inflammatory biomarker frequently used in clinical practice. However, insufficient evidence-based ordering inevitably results in its overuse or underuse. This study aims to predict its normal and abnormal levels using the deep neural network (DNN) models, helping clinicians order this item more appropriately and intelligently.

METHODS

We considered complete blood count (CBC) parameters as feature vectors and 10 mg/L as a cutoff value for CRP. Several models, including linear support vector classification, logistic regression, decision trees, random forests, and DNN, were developed based on a dataset of 53834 medical records to predict binary output. We externally validated DNN models on independent 20723 samples through discrimination, calibration curve, and decision curve analysis.

RESULTS

DNN models has the best area under the receiver operating characteristic curves (AUC). Learning curves revealed that models' AUC, balanced accuracy, and F1 score do not significantly and continuously improve following increasing data volume. In internal validation, the AUC, balanced accuracy, and the F1 score of 10 models were 0.818 (0.95 CI: 0.812-0.824), 0.741 (0.95 CI: 0.736-0.747), and 0.649 (0.95 CI: 0.643-0.656), respectively. These metrics were 0.817 (0.95 CI: 0.816-0.817), 0.741 (0.95 CI: 0.740-0.742), and 0.641 (0.95 CI: 0.640-0.642), respectively, in external validation. AUC and balanced accuracy shown no significant difference (P-values were 0.106 and 0.339). CRP10-C2 model has the lowest Brier score of 0.154, AUC of 0.818, and calibration curve formula of y=1.001x-0.010, which was identified as a target model to deploy in the app.

CONCLUSIONS

DNN models obtained moderate performance, surpassing baseline indices in distinguishing binary CRP levels. They are good generalizations and well-calibrated. The CRP-C2 model can enhance CRP utilization by informing the orders appropriately and can contribute to inflammatory diagnostics in primary health care where CBC is available, but the CRP test is inaccessible.

One-year follow-up effects of the informed health choices secondary school intervention on students' ability to think critically about health in Uganda: a cluster randomized trial

INTRODUCTION

We assessed the effects of the Informed Health Choices (IHC) secondary school intervention on students' ability to think critically about choices 1 year after the intervention.

METHODS

We randomized eighty secondary schools to the intervention or control (usual curriculum). The schools were randomly selected from the central region of Uganda and included rural and urban, government, and privately-owned schools. One randomly selected class of year-2 students (ages 14-17) from each school participated in the trial. The intervention included a 2-day teacher training workshop, 10 lessons accessed online by teachers and delivered in classrooms during one school term (May-August 2022). The lessons addressed nine prioritized IHC concepts. We used two multiple-choice questions for each concept to evaluate the students' ability to think critically about choices at both the end of the school term and again after 1 year. The primary outcome was the proportion of students with a passing score (≥ 9 of 18 questions answered correctly) on the "Critical Thinking about Health" (CTH) test.

RESULTS

After 1-year, 71% (1749/2477) of the students in the intervention schools and 71% (1684/2376) of the students in the control schools completed the CTH test. In the intervention schools, 53% (934/1749) of students who completed the test had a passing score compared to 33% (557/1684) of students in the control schools (adjusted difference 22%, 95% CI 16-28).

CONCLUSIONS

The effect of the IHC secondary school intervention on students' ability to assess health-related claims was largely sustained for at least 1 year.

Biennial Mammography Performance in the Korean National Cancer Screening Program From 2009 to 2020

OBJECTIVE

Mammography is essential for reducing breast cancer mortality; however, its performance varies globally. This study aimed to evaluate mammography screening outcomes in Korea over 12 years and investigate regional variations.

MATERIALS AND METHODS

We analyzed mammography data from 42 million Korean women, aged 40 years and older, who participated in the Korean National Cancer Screening Program (KNCSP) from 2009 to 2020. Performance metrics-including recall rate (RR), positive predictive value (PPV), sensitivity, specificity, false positive rate (FPR), cancer detection rate (CDR), interval cancer rate (ICR), and dense breast rate (DBR), were computed. Twelve-year trends in these metrics were analyzed using Joinpoint regression. Regional variations were also examined across Korea's 237 districts, stratified by age groups.

RESULTS

From 2009 to 2020, 42165405 mammography screenings were conducted through the KNCSP, increasing from 2821132 screenings in 2009 to 3596204 in 2020. The RR decreased from 17.2% in 2009 to 11.2% in 2020 (average annual percent change [AAPC] = -3.7%), while the PPV increased from 0.8% to 2.8%; AAPC = 10.7%), the CDR increased from 1.5 to 3.1 per 1000; AAPC = 7.3%), and the ICR rose from 0.9 to 1.6 per 1000; (AAPC = 5.2%). Regional variations were noted; however, differences in the RR, sensitivity, specificity, and FPR decreased over time.

CONCLUSION

While mammography performance improved from 2009 to 2020, the PPV and sensitivity remain suboptimal, underscoring the need for continuous monitoring. Regional disparities in performance, although reduced, persist. These findings provide essential baseline data for improving mammography quality and addressing inequities in breast cancer screening.

Selecting indicators for the measurement of low-value care using German claims data: A three-round modified Delphi panel

By reducing healthcare services that offer little benefit or potential harm to patients (low-value care), resources can be redirected towards more adequate treatments, improving healthcare efficiency and patient outcomes. This study aimed to systematically incorporate clinical expertise across medical disciplines through a Delphi process to establish indicators for measuring low-value care, ensuring their acceptance by medical societies, the broader medical community, and patients. We developed two versions (one with higher sensitivity and one with higher specificity) for almost each of the 42 indicators identified as potentially measurable in a previous systematic review. We conducted a three-round modified Delphi panel based on the RAND/UCLA appropriateness methodology, with 62 experts from 52 Scientific Medical Societies and professional organisations, and patient representatives. In round one, each indicator was rated for its ability to indicate low-value healthcare and its measurability in German claims data. This was followed by an online discussion in round two. The indicators were then modified based on expert feedback and re-assessed in round three. As a result, 24 indicators were deemed appropriate for measuring low-value care, covering areas such as pharmaceuticals, diagnostic tests, screening, and treatment. For example, one indicator identified patients with cancer who received chemotherapy in the last month of life. These indicators will help identify healthcare services that may require policy-level interventions to improve the quality of care. However, most low-value care indicators can only be measured in German claims data if documentation requirements for relevant information are expanded.

Social Media Posts About Medical Tests With Potential for Overdiagnosis

Importance

Social media is an influential source of medical information, but little is known about how posts discuss medical tests that carry potential for overdiagnosis or overuse.

Objective

To investigate how social media posts discuss 5 popular medical tests: full-body magnetic resonance imaging, the multicancer early detection test, and tests for antimullerian hormone, gut microbiome, and testosterone.

Design, Setting, and Participants

This cross-sectional study assessed posts on Instagram and TikTok between April 30, 2015, and January 23, 2024, that discussed full-body magnetic resonance imaging, the multicancer early detection test, and tests for antimullerian hormone, gut microbiome, and testosterone. Using keywords on newly created accounts, posts were searched and screened until 100 posts for each test on each platform were identified (n = 1000). Posts were excluded if they did not discuss 1 of the 5 tests or were not in English or if the account holders had fewer than 1000 followers.

Main Outcomes and Measures

The main outcome was information about benefits, harms, and overall tone discussed in the post. All outcomes were summarized descriptively. Logistic regression was used to assess whether the use of evidence or the account holder being a physician or having financial interests influenced how tests were discussed.

Results

A total of 982 posts from account holders with a combined 194 200 000 followers were analyzed. Across all tests, benefits were mentioned in 855 posts (87.1%) and harms in 144 (14.7%), with 60 (6.1%) mentioning overdiagnosis or overuse. Overall, 823 posts (83.8%) had a promotional (vs neutral or negative) tone. Evidence was explicitly used in 63 posts (6.4%), personal anecdotes were used in 333 (33.9%), 498 posts (50.7%) encouraged viewers to take action and get the test, and 668 account holders (68.0%) had financial interests. Posts from physicians were more likely to mention harms (odds ratio, 4.49; 95% CI, 2.85-7.06) and less likely to have an overall promotional tone (odds ratio, 0.53; 95% CI, 0.35-0.80).

Conclusions and Relevance

In this cross-sectional study of social media posts about 5 popular medical tests, most posts were misleading or failed to mention important harms, including overdiagnosis or overuse. These data demonstrate a need for stronger regulation of misleading medical information on social media.

Trends in resource utilization for new-onset psychosis hospitalizations at children's hospitals

BACKGROUND

Children with new-onset psychosis often require hospitalization for medical evaluation.

OBJECTIVES

The goal of this study was to assess variations in the management of children with new-onset psychosis and characterize trends in resource utilization.

METHODS

The study included index hospitalizations for children ages 7-18 admitted to children's hospitals with a primary diagnosis of psychosis from 2011 to 2022 using the Pediatric Health Information System (PHIS) database. Children with a complex chronic condition were excluded. Resource utilization categories included medication, imaging, laboratory, and other clinical resources. Variability in resource utilization was assessed using covariance tests for random intercepts with generalized linear modes after adjusting for age, sex, payor, and severity. Trends in resource utilization were examined using generalized estimating equations adjusting for the same factors and accounting for hospital clustering.

RESULTS

Our data set included 7126 new-onset psychosis hospitalizations from 37 children's hospitals. Teenage males and non-Hispanic Whites were most likely to be hospitalized. There was a significant variation in resource utilization across hospitals in all categories (p < .001). The most frequently utilized resources were antipsychotic medications (76%), serum chemistry (77%), toxicology labs (72%), and brain magnetic resonance imaging (22%). The most notable increases in utilization were in the performance of laboratory tests, brain imaging, anesthetic use, and intravenous immunoglobulin use.

CONCLUSION

Study findings suggest that there has been a stable rate of hospitalization for children with new-onset psychosis, yet a significant variation in the medical evaluation exists. Significant increases and variations in resource utilization across all categories suggest an emerging need for robust evidence and consensus-based practice guidelines.

Sex differences in treatment strategies for pulmonary embolism in older adults: The SERIOUS-PE study of RIETE participants and US Medicare beneficiaries

INTRODUCTION

Sex differences exist in risk factors and comorbidities of older adults (aged ⩾ 65 years) with pulmonary embolism (PE). Clinically relevant sex-based treatment disparities for PE have not been adequately addressed. The few existing show conflicting results due to small sample size (type II error) and suboptimal methods (overreliance on p-value, which may detect differences of small clinical relevance).

METHODS

We assessed sex differences in anticoagulation and advanced therapies for PE in older adults, utilizing data from Registro Informatizado Enfermedad TromboEmbolica (RIETE), a large PE registry with predominant participation from Europe, and data from US Medicare beneficiaries. We prespecified a standardized difference (SRD) > 10% as clinically relevant. RIETE included 33,462 (57.7% female) and Medicare included 102,391 (55.0% female) older adults with PE.

RESULTS

In RIETE, there were no overall sex differences in the use of anticoagulation (median: 181 vs 180 days, SRD < 1%), fibrinolysis (SRD < 3%), thrombectomy (SRD < 2%), or inferior vena cava (IVC) filters (SRD: 4.4%). However, fibrinolytic therapy (systemic or catheter-based) was less often used in female than male patients with intermediate-risk PE (8.0% vs 12.1%, SRD: 13.6%). No sex differences were noted with advanced PE therapies in Medicare beneficiaries. In unadjusted analyses, fibrinolysis and IVC filter placement were more frequent in Medicare than RIETE participants regardless of sex (p < 0.001).

CONCLUSION

In a predominantly European PE registry and a US study of older adults, there were no overall sex differences in anticoagulation patterns or advanced therapy utilization. Future studies should determine if sex disparities in fibrinolytic therapy for intermediate-risk PE and greater use of advanced therapies in US older adults correlate with clinical outcomes.

Understanding Noninferiority Trials: What Stroke Specialists Should Know

Noninferiority trials aim to prove that the efficacy, defined in terms of a key clinical outcome, of a new treatment is not meaningfully worse than that of an established active control. Noninferiority trials are important when other aspects of care can be improved, such as convenience, toxicity, costs, and safety (nonefficacy benefits). While the motivation for a noninferiority trial is straightforward, the design, execution, and interpretation of these trials is not a trivial task. Several safeguards that protect superiority trials from incorrect conclusions do not apply or even work in reverse for noninferiority trials. This review aims to provide stroke clinicians and researchers with a general overview of noninferiority trials and a deeper understanding of 10 pitfalls they should consider when designing and interpreting such trials.

Development of International Quality Measures Targeting Low-Value Care in Hand Surgery

PURPOSE

Low-value care, defined as care in which there is no evidence of benefit, increases the risk of harm, or adds unnecessary costs, persists in hand and upper extremity care globally. To date, there are no quality measures to measure low-value care for a global setting. We aimed to develop international quality measures that are important, feasible, usable, and scientifically acceptable for reducing low-value care in hand surgery.

METHODS

We performed a literature review to identify areas of potential low-value care for hand surgery. A consortium of 11 United States-based surgeons with experience in hand and upper-extremity surgery and/or quality measure development completed a modified Research and Development (RAND)/ University of California, Los Angeles (UCLA) Delphi Appropriateness process to evaluate the importance, feasibility, usability, and scientific acceptability of 10 candidate quality measures to reduce low-value hand surgical care. A modified RAND/UCLA Delphi Appropriateness process was subsequently conducted that included a panel of 20 international hand surgeons who voted on the same 10 measures using the same voting criteria. Panelist agreement or disagreement was assessed using predetermined criteria.

RESULTS

United States and international panelists achieved agreement on the four criteria for five of the 10 measures; thus, these five measures were deemed valid. These measures include minimizing the unnecessary use of immobilization for fifth metacarpal neck fractures, postinjury imaging of distal radius fractures, perioperative antibiotics for soft tissue hand surgery, pre-operative testing, and opioid use after hand surgery. Two measures were deemed valid by the US panelists only, and two measures were deemed valid by the international panel only.

CONCLUSIONS

United States- and international-based hand and upper-extremity surgeons achieved consensus on an international quality measure portfolio to reduce low-value care in hand surgery, which may vary in practices settings globally.

CLINICAL RELEVANCE

These quality measures may be used to reduce low-value care in many types of health systems globally.

Overuse of medical imaging and effects of payer-provider integration: quasi-experimental evidence from Finland

BACKGROUND

Healthcare expenditures have risen in middle- and high-income countries. One of the potential contributors is the overuse of diagnostics. I explore whether medical imaging is overused when privately owned clinics in Finland treat patients with voluntary private health insurance (VPHI).

METHODS

I employ administrative insurance claims data from a major Finnish insurance company, covering 2016-2019, and exploit two market entries of clinics owned by the company in 2017. The underlying assumption is that the insurance company's own clinics had weaker incentives to overuse imaging than other privately owned clinics because the payer and the provider belonged to the same entity. I identify the overuse using the staggered difference-in-differences (DID) strategy, in which I consider patients from cities with a market entry as the treatment group and compare them to patients in other similar cities.

RESULTS

I find that the market entries decreased the use of radiography and ultrasound imaging in the treatment of VPHI policyholders, suggesting that private clinics overused these imaging technologies. The more expensive computed tomography (CT) and magnetic resonance imaging (MRI) were, however, not overused.

CONCLUSIONS

The results show that private clinics in Finland overused some imaging technologies when treating VPHI policyholders. The extent and magnitude of overuse can, however, vary considerably between imaging technologies and medical ailments.

National trends in catheter angiography and cerebrovascular imaging in a group of privately insured patients in the US

BACKGROUND

Despite the increasing use of non-invasive imaging, DSA remains the gold standard for cerebrovascular imaging. However, trends in DSA utilization are poorly understood. The goal of this study was to describe DSA utilization in a large claims database in the US over a 13 year period.

METHODS

This retrospective cohort study assessed a nationwide database of privately insured individuals from 2005 to 2018 for patients undergoing cranial CT angiography (CTA), MR angiography (MRA), and DSA. We assessed trends in the overall use of and indications for each modality. For DSA, we examined the types of performing proceduralists.

RESULTS

Among patients undergoing DSA in 2018, median age was 52 years, and 60% were women. MRA and DSA use decreased, from 289 to 275 claims, and from 38 to 29 claims per 100 000 enrollees, respectively, while CTA use increased from 31 to 286 claims per 100 000 enrollees. These trends differed by geographic region and indication. Nearly half of DSA procedures but <25% of non-invasive imaging were inpatient studies. DSA performed by neurosurgeons increased from 0.5 to 4.1 while those performed by radiologists decreased from 7.2 to 4.0 studies per 100 000 enrollees.

CONCLUSIONS

DSA use decreased slightly while CTA use increased by ninefold. The reasons for this change are likely complex and may reflect more aggressive imaging for stroke, increased detection of incidental findings, and increased quality of non-invasive imaging. Over time, the proportion of DSA procedures performed by neurosurgeons overtook that performed by radiologists.

Will the increase of medical equipment affect medical expenditure? Empirical evidence from a quasi-experiment in China

BACKGROUND

Many studies have shown that using new technologies and medical equipment contributes to increasing health expenditure. Relatively less empirical studies have measured the impact of medical equipment on rising medical costs in China. Against this backdrop, we aim to examine whether the large-scale medical equipment deployment explains the increase in health expenditure.

METHODS

Quasi-experimental research design with a difference-in-differences approach was adopted to explore whether an increase in the number of large-scale medical equipment impacts on outpatient and inpatient costs. Data were obtained from the 2011-2017 Health Financial Annals in Shaanxi province, China.

RESULTS

The increase in the number of large-scale medical equipment by 1 - regardless of the initial configuration - resulted in the increase of the average cost per outpatient visit and the average cost per inpatient visit by 10.6% (p < 0.05) and 8.0% (p < 0.05), respectively. Our complex difference in differences model illustrates that the increase in the number of large-scale medical equipment by 1 - regardless of the initial configuration-results in an increase in the average diagnostic cost per outpatient visit and the average diagnostic cost per inpatient visit by 27. 3% (p < 0.01) and 25. 5% (p < 0.01), respectively.

CONCLUSIONS

Our findings show that the medical expenditure differs significantly with the increase in the number of large-scale medical equipment. This study mainly revealed the relationship between the growth of the number of large-scale medical equipment and medical expenditure. Our novel perspective was used to measure the phenomenon of excessive use, and to explain the social phenomenon of inaccessible and expensive medical care in China.

Decreased risk of cardiovascular disease mortality associated with occasional positive screens following cancer screenings

Positive results from cancer screenings, like a cancer diagnosis, can increase the risk of cardiovascular disease (CVD) mortality due to heightened psychological stress. However, positive screening results may also serve as a teachable moment to encourage the adoption of a healthier lifestyle. Consequently, the overall association between positive screenings and CVD mortality risk remains unclear. Based on PLCO data, the risk of CVD mortality associated with the number and types of positive screens was evaluated using Cox regression models among 149,258 eligible participants enrolled between 1993 and 2001. Additional analyses explored these associations stratified by prior CVD history. Exploratory analyses were also conducted to investigate whether positive screens were linked to the potential adoption of a healthier lifestyle. After a median follow-up of 19 years, significantly decreased risk of CVD mortality was observed for individuals with occasional positive screening (≤ 2 positive screens) [adjusted hazard ratio (HR, 95%CIs): 0.931 (0.897-0.968), P < 0.001] compared to the control arm. This effect was particularly notable for flexible sigmoidoscopy [0.842 (0.802-0.884), P < 0.001] and transvaginal ultrasound [0.855 (0.776-0.942), P = 0.002]. However, when the number of positive screens increased to more than two, the reduced risk of CVD mortality became non-significant [0.977 (0.941-1.014), P = 0.220]. Subgroup analyses revealed a greater reduction in CVD mortality risk among participants without a history of CVD [0.917 (0.864-0.973)] compared to those with a history of CVD [0.944 (0.898-0.993)]. Sensitivity analyses excluding screening-detected cancers showed similar association in the overall population [0.933 (0.897-0.970)], as well as in both subgroups with [0.945 (0.898-0.995)] and without previous CVD [0.919 (0.865-0.976)]. Exploratory analyses indicated a significantly higher proportion of any body mass index (BMI) reduction among those with a baseline BMI ≥ 25 kg/m2 who had positive screens compared to the control arm, particularly for individuals with occasional positive screens (48.07% vs. 47.04%, P value = 0.037). Occasional positive cancer screening are associated with reduced risk of CVD mortality, regardless of prior CVD history, cancer diagnosis, and other competitive risks.

Advancing drug delivery research: sustainable strategies for innovation and translation

Sustainable systems are designed to promote lasting viability and resilience while reducing negative effects on the environment, society, and economy. Like many others, the drug delivery field is facing the challenges of the global environmental crisis. Despite its rapid growth and significant funding, there has been a noticeable slowdown in the rate of advancement, impacting the economy, society, and environment. This paper delves into sustainable strategies for drug delivery research, including reducing pill burden through controlled release systems, use of bio-degradable/absorbable polymers, reduction in excipient requirements and use of functional excipients, clinically viable drug delivery system designs, non-invasive/self-administration technologies, and use of relevant in vitro and in vivo tools and computational approaches. When adopted, these strategies can help researchers create widely available, reasonably priced, and ecologically friendly drug delivery systems, thereby advancing sustainable healthcare for all. The manuscript also advocates for funding policies that support sustainable drug delivery research. It underscores the need to integrate sustainability principles into drug delivery research to achieve the broader agenda of global sustainability and well-being, such as SDG 3 (Good Health and Well-being), SDG 7 (Affordable and Clean Energy), SDG 9 (Industry, Innovation, and Infrastructure), and SDG 12 (Responsible Consumption and Production).

Development and usability testing of a multifaceted intervention to reduce low-value injury care

BACKGROUND

Multifaceted interventions that address barriers and facilitators have been shown to be most effective for increasing the adoption of high-value care, but there is a knowledge gap on this type of intervention for the de-implementation of low-value care. Trauma is a high-risk setting for low-value care, such as unnecessary diagnostic imaging and the use of specialized resources. The aim of our study was to develop and assess the usability of a multifaceted intervention to reduce low-value injury care.

METHODS

We used the Consolidated Framework for Implementation Research and the Expert Recommendations for Implementing Change tool as theoretical foundations to identify barriers and facilitators, and strategies for the reduction of low-value practices. We designed an initial prototype of the intervention using the items of the Template for Intervention Description and Replication. The prototype's usability was iteratively tested through four focus groups and four think-aloud sessions with trauma decision-makers (n = 18) from seven Level I to Level III trauma centers. We conducted an inductive analysis of the audio-recorded sessions to identify usability issues and other barriers and facilitators to refine the intervention.

RESULTS

We identified barriers and facilitators related to individual characteristics, including knowledge and beliefs about low-value practices and the de-implementation process, such as the complexity of changing practices and difficulty accessing performance feedback. Accordingly, the following intervention strategies were selected: involving governing structures and leaders, distributing audit & feedback reports on performance, and providing educational materials, de-implementation support tools and educational/facilitation visits. A total of 61 issues were identified during the usability testing, of which eight were critical, 33 were moderately important, and 18 were minor. These issues led to numerous improvements, including the addition of information on the drivers and benefits of reducing low-value practices, changes in the definition of these practices, the addition of proposed strategies to facilitate de-implementation, and the tailoring of educational/facilitation visits.

CONCLUSIONS

We designed and refined a multifaceted intervention to reduce low-value injury care using a process that increases the likelihood of its acceptability and sustainability. The next step will be to evaluate the effectiveness of implementing this intervention using a pragmatic cluster randomized controlled trial.

Primary healthcare's carbon footprint and sustainable strategies to mitigate its contribution: a scoping review

BACKGROUND

The escalating climate crisis poses a significant threat to global public health. The healthcare sector, designed to protect human health is a major contributor to greenhouse gas emissions, and thus, a key driver of climate degradation. This paradox endangers both planetary and human health, making the decarbonization of healthcare, including primary care, critical. However, research on primary care's contribution to emissions and strategies for mitigation remains limited.

AIM

This scoping review aimed to map how primary care contributes to healthcare's environmental footprint and determine contributing factors. Additionally, it sought to identify existing and innovative strategies to reduce the carbon footprint of primary healthcare.

METHODS

A comprehensive strategy was developed to systematically search both published databases and grey literature. Key terms were identified and employed in the exploration of relevant databases and internet search engines.

RESULTS

An initial search yielded 246 published articles and 25 grey literature sources. 14 additional articles were included following forward and backward searching of prominent authors and key articles. After screening and full-text review, 39 articles and 12 reports/toolkits were included. The majority of sources were opinion pieces, with limited quantitative, observational, or qualitative studies. Primary care's carbon footprint can be classified into clinical and non-clinical sources, with significant impacts from pharmaceuticals and inhaler propellant gases. Contributing factors include limited knowledge of emission sources, lack of awareness of sustainable practices, low prioritization of sustainability, barriers including ethical concerns and over-medicalization. Identified strategies to reduce emissions include decarbonization of patient care, increasing education and awareness, implementing non-clinical decarbonization efforts, and conducting more research to support sustainable initiatives. Developing metrics to track progress and securing policy supports to improve adoption and implementation were also highlighted as critical.

CONCLUSION

The identification of sources of carbon hotspots in primary care is an essential precursor to enable the development of targeted decarbonization strategies. Decarbonizing primary care requires a multifaceted approach that addresses the underlying factors driving unsustainable practices. This would allow healthcare professionals to effectively balance the provision of high-quality patient care, while reducing their environmental impact, ultimately improving both human and planetary health.

Patient characteristics and healthcare use for high-cost patients with musculoskeletal disorders in Norway: a cohort study

BACKGROUND

A high proportion of healthcare costs can be attributed to musculoskeletal disorders (MSDs). A small proportion of patients account for most of the costs, and there is increasing focus on addressing service overuse and high costs. We aimed to estimate healthcare use contributing to high costs over a five-year period at the individual level and to examine if healthcare use for high-cost patients is in accordance with guidelines and recommendations. These findings contribute to the understanding of healthcare use for high-cost patients and help in planning future MSD-care.

METHODS

This study combined Norwegian registries on healthcare use, diagnoses, demographic, and socioeconomic factors. Patients (≥ 18 years) were included by their first MSD-contact in 2013-2015. We analysed healthcare use during the subsequent five years. Descriptive statistics were used to compare high-cost (≥ 95th percentile) and non-high-cost patients. Total healthcare contacts and costs for high-cost patients were examined stratified by number of hospitalisations and surgical treatments. Healthcare use of General Practitioners (GPs), physiotherapy, chiropractor and Physical Medicine and Rehabilitation physicians prior to the first hospitalisation or surgical treatment for a non-traumatic MSD was registered.

RESULTS

High-cost patients were responsible for 61% of all costs. Ninety-four percent of their costs were related to hospital treatment. Ninety-nine percent of high-cost patients had at least one hospitalisation or surgical procedure. Out of the high-cost patients, 44% had one registered hospitalisation or surgical procedure, 52% had two to four and 4% had five or more. Approximately 30-50% of patients had seen any healthcare personnel delivering conservative treatment other than GPs the year prior to their first hospitalisation/surgical treatment for a non-traumatic MSD.

CONCLUSION

Most healthcare costs were concentrated among a small proportion of patients. In contrast to guidelines and recommendations, less than half had been to a healthcare service focused on conservative management prior to their first hospitalisation or surgical treatment for a non-traumatic MSD. This could indicate that there is room for improvement in management of patients before hospitalisation and surgical treatment, and that ensuring sufficient capacity for conservative care and rehabilitation can be beneficial for reducing overall costs.

Associations of care continuity and care coordination with the overuse of healthcare services: a nationwide population-based study

BACKGROUND

Care continuity and care coordination have received increased attention as important ways of decreasing overuse/low-value care. Prior research has verified an association between care continuity and overuse or an association between care coordination and overuse. However, little is known about the relative influences of care continuity and care coordination on overuse. We used nationwide population-based data from Taiwan to examine the relative associations of care continuity and care coordination with overuse.

METHODS

We analyzed 1,462,960 beneficiaries in 2015 randomly sampled from all people enrolled in the Taiwan National Health Insurance. Having adjusted for patient characteristics, the multivariable logistic regression model was used to examine the associations of the Continuity of Care (COC) Index and care density on overuse, using a previously validated set of 18 potentially low-value care services.

RESULTS

Higher COC index was associated with lower overuse (low vs. medium: odds ratio [OR], 1.11; 95% confidence interval [CI], 1.09-1.12; high vs. medium: OR, 0.80; 95% CI, 0.795-0.813). Higher care density was associated with lower overuse (low vs. medium: OR, 1.01; 95% CI, 1.001-1.024; high vs. medium: OR, 0.88; 95% CI, 0.87-0.89).

CONCLUSIONS

Increased care continuity and care coordination are associated with decreased overuse. Facilitating care continuity and care coordination may be an important strategy for reducing overuse/low-value care.

Diversity, equity and inclusiveness in healthcare: A primary care perspective

Addressing Diversity, Equity and Inclusion in health care is a multidimensional challenge. From a US perspective, the third-party payment system has disempowered and depersonalized health-care delivery. The net result is wasteful and inefficient use of human and financial resources, burnout among providers, as well as care inequities. Financial integration at the point of patient care is essential to aligning the needs of patients with advances in medical technology. Complexity theory offers valuable insights into the roles of government, intermediaries and patients. The government must focus on equity as a rule compiler and referee of the system. Patient and providers who are actively engaged in shared decision-making will naturally address the diverse needs of multitudinous communities. Intermediaries address inclusion by connecting resources with the point of care. In a dynamic, emerging health-care system that serves diverse communities, patient and community-based financing, vouchers and defined contributions are necessary first steps in addressing cultural diversity, inclusion and equity.

Interventions to reduce low-value care in intensive care settings: a scoping review of impacts on health, resource use, costs, and the environment

PURPOSE

Low-value care is common in intensive care units (ICUs), unnecessarily exposing patients to risks and harms, incuring costs to the patient and healthcare system, and contributing to healthcare's carbon footprint. We aimed to identify, collate, and summarise published evidence on the impact of interventions to reduce low-value care in ICUs.

METHODS

We searched MEDLINE, Embase, and Cochrane CENTRAL from inception to 22 September 2023 for evaluations of interventions aiming to reduce low-value care, supplemented by reference lists and recently published articles. We recorded impacts on the low-value target, health outcomes, resource use, cost, and the environment.

RESULTS

From 1155 studies screened, 32 eligible studies were identified evaluating interventions to reduce: routine blood testing (n = 13), routine chest X-rays (n = 10), and other types (or multiple types) of low-value care (n = 9). All but 3 of the interventions found reductions in the immediate low-value care target (usually the primary outcome). Although the small sample size of most included studies, limited their ability to detect impacts on other outcomes, many interventions were also associated with improved health outcomes and financial savings. The only study that reported environmental impacts found the intervention was associated with reduced carbon dioxide equivalent (CO2-e) emissions.

CONCLUSIONS

Interventions to reduce low-value care in ICUs may have important health, financial, and environmental co-benefits. Further research may inform wider scale-up and sustainability of successful strategies to decrease low-value healthcare. More empirical evidence on potential environmental benefits may inform policies to lower healthcare's carbon footprint.

Medical emergencies in hospital: The role of treatment escalation plans in out-of-hours decision-making

BACKGROUND

Out-of-hours medical emergencies are common in acute hospitals, and are often attended by staff who are unfamiliar with the patient's clinical background. Information in the hospital notes may or may not include guidance about how best to deal with clinical deterioration. The use of Treatment Escalation Plans (TEPs) attempts to address these deficiencies.

METHODS

This was an observational, questionnaire-based evaluation of the experience of trainee hospital doctors who attended out-of-hours medical emergencies.

RESULTS

Sixty-five medical emergencies were evaluated by a total of 38 doctors. Thirty patients had a TEP, attended by 20 doctors, and 35 without a TEP were attended by 27 doctors. Information from medical notes to facilitate decision-making was deemed sufficient by the attending doctor in 77% of patients with a TEP, compared to 54% of patients with no TEP. Only 10% of patients with a TEP had their treatment escalated at the time of the call, whereas this occurred in 20% of patients without a TEP (NS). A TEP was deemed 'somewhat' or 'very' helpful by trainees in 21/30 of the cases who had one. In 27/35 cases who did not have a TEP, trainees deemed that it would have been helpful to have had one. Twelve of 38 participants (32%) considered that there was a discrepancy between what was 'expected' and what they considered to be 'right' when managing out-of-hours emergencies.

CONCLUSION

TEPs have an important role in delivering key information that shapes out-of-hours decision-making in deteriorating patients. Both objective outcomes and the subjective quality of medical decision-making are enhanced when a TEP is available.

Exploring the risks of fragmentation in health care markets - An analysis of inpatient care in Georgia

Private providers play an important role in health systems in low-and middle-income countries. In many such contexts, markets are characterized by a high number of relatively small private facilities. The potential risks from highly concentrated healthcare markets are well-researched, and feature in the "Theories of Harm" investigated by competition regulators. However, there is limited evidence on markets that exhibit substantial harms as a result of very low concentration. This paper explores the risks associated with such market fragmentation, drawing on the example of Georgia, which has a largely privatized provider network. We used a mixed-method study design to analyze the inpatient market in Georgia. Market structure was described using administrative data on bed capacity and discharge numbers and geo-location data on travel time between facilities. The implications of the market structure were explored through in-depth interviews (n = 35) with policymakers, healthcare managers, and local experts and an anonymous online survey of similar groups (n = 97). Georgia's inpatient sector is characterized by a high number of small hospitals in terms of bed numbers and inpatient volumes, mitigated to a limited degree by the presence of provider networks. Travel time to the 3rd nearest competitor was extremely short, ranging from 3 to 5 min in big cities to 10 min in small towns and 33 min in remote locations. The fragmented nature of the market, together with inadequate regulatory and purchasing mechanisms, was argued to exacerbate challenges in the availability and competence of clinical staff, while the financial challenges caused by intense competition encouraged wasteful marketing, harmful cost-cutting measures, and demand inducement. We present "Theories of Harm" from market fragmentation, and argue that an effective policy response requires market-shaping activities using regulatory, financing, and purchasing mechanisms to encourage appropriate levels of market consolidation and so enhance quality, efficiency, and effective governance.

The paradox of convenience: how information overload in mHealth apps leads to medical service overuse

Background

Mobile health applications (mHealth) have become an indispensable tool in the healthcare industry to provide users with efficient and convenient health services. However, information overload has led to significant information overload problems in mHealth applications, which may further lead to overuse of medical services.

Methods

The purpose of this study was to explore the relationship between information overload and overuse of medical services in mHealth applications through health belief model (HBM). Data were collected from 1,494 respondents who were sampled through a simple random approach. A structured questionnaire was used as the instrument for data collection from mobile APP users in Guangdong Province between February 4, 2024, and February 20, 2024. Structural equation modeling (SEM) was used to analyze the data to investigate the effects of information overload on users' perceived severity, susceptibility, treatment benefits, barriers, self-efficacy, and action cues, which further influence the overuse of health care services.

Results

The study found that information overload significantly affected users' perceived severity, susceptibility, treatment benefits, barriers, self-efficacy, and action cues, and subsequently affected overuse of health care services. These results provide valuable insights for mHealth application developers, healthcare providers, and policy makers.

Conclusion

This study highlights the importance of effectively managing information delivery in mHealth applications to reduce the risk of overuse of healthcare services. The study not only highlights the dark side of information overload in mHealth applications, but also provides a framework to understand and address the challenges associated with information overload and service overuse in the mHealth context.

Low-value practices in primary care: a cross-sectional study comparing data between males and females in Spain

INTRODUCTION

Overuse of medical services is a challenge worldwide, posing a threat to the quality of care, patient safety and the sustainability of healthcare systems. Some data suggest that females receive more low-value practices (LVPs)-defined as medical interventions that provide little or no benefit to patients and can even cause harm-than males. This study aims to evaluate and compare the occurrence of LVPs in primary care among both males and females.

DESIGN

A retrospective study was conducted.

SETTING

Primary care in the Alicante province (Spain) during 2022.

PARTICIPANTS

Data were extracted from the digital medical records of 978 936 patients attended by 1125 family physicians across 262 primary healthcare centres in the Alicante province.

OUTCOME MEASURES

Data on age, sex, diagnosis and treatment were extracted. The primary outcome measure was the frequency of 12 selected LVPs prescribed to male and female patients. These LVPs were expected to be relatively frequent occurrences with the potential to cause harm.

RESULTS

A total of 45 955 LVPs were identified, of which 28 148 (5.27% of 534 603, CI95% 5.20-5.32) were prescribed to female patients and 17 807 (4.00% of 444 333, CI95% 3.95-4.06) to male patients (x², p value <0.0001). The most common LVPs were prescribing treatment for overactive bladder without excluding other pathologies that may cause similar symptoms (30.87%), using hypnotics without having a previous aetiological diagnosis in patients with difficulty maintaining sleep (14%) and recommending analgesics (NSAIDs, paracetamol and others) for more than 15 days per month in primary headaches that do not respond to treatment (13.33%).

CONCLUSIONS

Future clinical training, management and research must consider biological differences or those based on gender factors when analysing the frequency and causes of LVP.

Quantifying Low-Value Care in Germany: An Observational Study Using Statutory Health Insurance Data From 2018 to 2021

OBJECTIVES

Low-value care refers to medical services whose benefits do not outweigh the costs and potential harm. This study estimates the prevalence, distribution, and associated costs of 24 low-value care services within the German public healthcare system.

METHODS

This study was designed as a large-scale retrospective observational study using statutory health insurance data provided by the Techniker Krankenkasse, spanning from 2018 to 2021, covering approximately 11.1 million insured individuals annually. The prevalence of 24 low-value service indicators, which were identified through a systematic review and expert consultations, was calculated. To address uncertainties in distinguishing between appropriate and low-value care, both broad (potential overestimation) and narrow definitions (potential underestimation) were applied to all suitable indicators, providing a range within which the true extent of low-value care is expected to lie.

RESULTS

Between 2019 and 2021, 1.6 million patients were identified as having received at least 1 low-value service using the 24 indicators. Of all 10.6 million delivered services (cases) evaluated, on average per year, 1.1 million cases (broad definition) and 0.43 million cases (narrow definition) were classified as low-value care, corresponding to 10.4% and 4.0%, respectively. The costs incurred by the identified services were approximately euros €15.5 million (broad definition) and €9.9 million (narrow definition) annually.

CONCLUSIONS

Despite the limitations of German statutory health insurance data, considerable low-value care was found within several of the 24 low-value indicators. The findings highlight the necessity for targeted interventions to mitigate low-value care in Germany, guiding healthcare policy and practice to enhance quality and safety effectively.

Sufficiency health-wise: sustainable paths towards planetary and public health

Planet Earth is threatened by the human population. Energy and resource use are far beyond the planet's carrying capacity. Planetary Health suggests an alternative idea of prosperity as the best possible human health for all within planetary boundaries. This implies giving priority to ecology because human health depends ultimately on the integrity of the global biosphere. This paper presents a Health Sufficiency Framework, based on the Doughnut Economics Model. It is meant to fuel discussions on delicate topics of the required transformations of health care and public health.

A Tailored De-Implementation Strategy to Reduce Low-Value Home-Based Nursing Care: A Mixed-Methods Feasibility Study

AIM

To facilitate the delivery of appropriate care, the aim was to test if a tailored, multifaceted de-implementation strategy (RENEW) (1) would lead to less low-value nursing care and (2) was acceptable, implementable, cost effective and scalable in the home-based nursing care context.

DESIGN

A mixed-methods design.

METHODS

The RENEW strategy with components on education, persuasion, enablement, incentives and training was introduced in seven teams from two organisations in the Netherlands. To estimate the effect size, data were collected at baseline (T0) and follow-up measurement (T1), on the volume of care in both frequency and time in minutes per week and independent samples t-tests were performed. A qualitative evaluation was conducted to understand feasibility aspects, see how the strategy works and identify influencing factors and used document analyses and semi-structured interviews. Deductive coding was used to analyse the results.

RESULTS

The time spent on low-value nursing care (mean, minutes per week per client) in seven teams for 210 clients in T1 compared to 222 clients in T0 reduced statistically significant. The difference between T0 and T1 equals 17.94%. The frequency of delivered low-value nursing care (mean per week) reduced but not statistically significant. From the transcripts of eight semi-structured interviews and documents, a list of 79 influencing factors were identified. Practical implementation tools, workplace coaching and sharing experiences within and between teams were considered as the most contributing elements.

CONCLUSION

The results showed that for the seven home-healthcare teams in this study, the RENEW strategy (1) leads to a reduction in low-value care and (2) is-conditional upon minor modifications-acceptable, implementable, cost effective and scalable.

Identifying and prioritizing inefficiency causes in Iran's health system

BACKGROUND

Enhancing efficiency is crucial in addressing the escalating scarcity of healthcare resources. It plays a pivotal role in achieving Universal Health Coverage (UHC), with the ultimate goal of ensuring health equity for all. A fundamental strategy to bolster efficiency involves pinpointing the underlying causes of inefficiency within the healthcare system through empirical research. This study aimed to determine and prioritize the causes of inefficiency in Iran's health system.

METHODS

This mixed-method study comprised three phases. The initial phase involved identifying the causes of inefficiency through a comprehensive literature review of relevant studies published between January 1, 2010, to January 1, 2021. The causes were then aligned and prioritized using criteria derived from the literature and expert opinion. Finally, the identified causes were ranked based on their significance using Multiple-Criteria Decision Analysis (MCDA).

RESULTS

From an initial pool of 307 causes of inefficiency, they were reduced to 121 causes in the first round of screening which were categorized into 13 thematic topics. The second screening process further narrowed the list to 48 causes. Among these, the leading causes of inefficiency included the inadequate supply and unequal distribution of hospital beds, the overuse of health services, and the mismanagement of the health workforce. In contrast, the use of traditional treatment methods was determined to be the least significant factor contributing to inefficiency.

CONCLUSION

This study identified key inefficiencies in Iran's health system, such as resource misallocation, overuse of services, and workforce mismanagement. Addressing these issues is essential for optimizing resource utilization, enhancing service delivery, and achieving UHC. The findings suggest that policymakers should prioritize reforms in hospital bed distribution, implement strategies to reduce unnecessary health service use, and strengthen human resource management. Additionally, targeted policies that focus on decentralizing healthcare decision-making and enhancing primary care could significantly improve system-wide efficiency. Future research should evaluate the effectiveness of these interventions and explore the role of digital health solutions in mitigating identified inefficiencies.

Unnecessary care in orthopaedic surgery

Unnecessary care, where the potential for harm exceeds the potential for benefit, is widespread in medical care. Orthopaedic surgery is no exception. This has significant implications for patient safety and health care expenditure. This narrative review explores unnecessary care in orthopaedic surgery. There is wide geographic variation in orthopaedic surgical practice that cannot be explained by differences in local patient populations. Furthermore, many orthopaedic interventions lack adequate low-bias evidence to support their use. Quantifying the size of the problem is difficult, but the economic burden and morbidity associated with unnecessary care is likely to be significant. An evidence gap, evidence-practice gap, cognitive biases, and health system factors all contribute to unnecessary care in orthopaedic surgery. Unnecessary care is harming patients and incurring high costs. Solutions include increasing awareness of the problem, aligning financial incentives to high value care and away from low value care, and demanding low bias evidence where none exists.

Success factors for interventions to reduce low-value imaging. Six crucial lessons learned from a practical case study in Norway

BACKGROUND

Substantial overuse of health care services is identified and intensified efforts are incited to reduce low-value services in general and in imaging in particular.

OBJECTIVE

To report crucial success factors for developing and implementing interventions to reduce specific low-value imaging examinations based on a case study in Norway.

MATERIALS AND METHODS

Mixed methods design including one systematic review, one scoping review, implementation science, qualitative interviews, content analysis of stakeholders' input, and stakeholder deliberations.

RESULTS

The description and analysis of an intervention to reduce low-value imaging in Norway identifies six general success factors: 1) Acknowledging complexity: advanced knowledge synthesis, competence of the context, and broad and strong stakeholder involvement is crucial to manage de-implementation complexity. 2) Clear consensus-based criteria for selecting low-value imaging procedures are key. 3) Having a clear target group is critical. 4) Stakeholder engagement is essential to ascertain intervention relevance and compliance. 5) Active and well-motivated intervention collaborators is imperative. 6) Paying close attention to the mechanisms of low-value imaging and the barriers to reduce it is decisive.

CONCLUSION

Reducing low-value imaging is crucial to increase the quality, safety, efficiency, and sustainability of the health services. Reducing low-value imaging is a complex task and paying attention to specific practical success factors is key.

Strengthening the pain care ecosystem to support equitable, person-centered, high-value musculoskeletal pain care

ABSTRACT

Improving health and wellbeing outcomes for people experiencing chronic musculoskeletal pain requires collective efforts across multiple levels of a healthcare ecosystem. System-wide barriers to care equity must however be addressed (eg, lack of co-designed services; overuse of low value care/underuse of high value care; inadequate health workforce; inappropriate funding models; inequitable access to medicines and technologies; inadequate research and innovation). In this narrative review, utilizing a systems' thinking framework, we synthesize novel insights on chronic musculoskeletal pain research contextualized through the lens of this complex, interconnected system, the "pain care ecosystem." We examine the application of systems strengthening research to build capacity across this ecosystem to support equitable person-centred care and healthy ageing across the lifespan. This dynamic ecosystem is characterized by three interconnected levels. At its centre is the person experiencing chronic musculoskeletal pain (micro-level). This level is connected with health services and health workforce operating to co-design and deliver person-centred care (meso-level), underpinned further upstream by contemporary health and social care systems (macro-level context). We provide emerging evidence for how we, and others, are working towards building ecosystem resilience to support quality musculoskeletal pain care: at the macro-level (eg, informing musculoskeletal policy and health strategy priorities); at the meso-level (eg, service co-design across care settings; health workforce capacity); and downstream, at the micro-level (eg, person-centred care). We outline the mechanisms and methodologies utilized and explain the outcomes, insights and impact of this research, supported by real world examples extending from Australian to global settings.

General dentists' treatment plans in response to cosmetic complains; a field study using unannounced-standardized-patient

Background

This field study explored general dentists' treatment plans in response to the request for cosmetic services of an unannounced standardized patient (USP) in Mashhad, Iran.

Methods

The researcher, as a USP, visited 24 and 23 offices in a high-income and a low-income area, respectively. The primary complaint was that, according to her friend's comments, a dental student, her smile was "crooked and yellow" due to the congenitally missing tooth number 10 and peg-shaped tooth number 8. The dentists' treatment plans for teeth color and form and the cosmetic services expenses were recorded. The treatment plans of the two areas were compared.

Results

For dental form, most dentists' treatment plans were categorized as "No intervention" (privileged area: 37.5 %, less-privileged area: 56.53 %, and total: 46.80 %). The percentage of dentists in the privileged area who prescribed cosmetic services was twice that of the less-privileged area (33.33 % versus 17.39 %). The intervention for dental form varied from placing 1 unit of composite veneer to 10 units of ceramic laminates or orthodontics with a wide range of treatment costs ($42.09 to $1079.14). For tooth color, most dentists (privileged area: 62.50 %, less-privileged area: 30.43 %, and total: 46.80 %) were categorized as "Interventionists." For tooth color, the treatment plans varied from scaling and root planing, bleaching, and composite veneer with various costs ($7.19 to $197.84).

Conclusion

Cosmetic treatment plans and expenses varied significantly for a single USP, with many not aligning with the standard treatment plan. Some dentists offered treatments even without a chief complaint from the patient. Dentists in privileged areas were twice as likely to prescribe cosmetic treatments compared to those in less privileged areas. Therefore, cosmetic services necessitate monitoring, establishing clear diagnostic criteria, and implementing educational interventions.

The application of medical ethics in the developing countries - A neurosurgical perspective

Introduction

Neurosurgery is one of the rapidly evolving specialities of medical science, where the neurosurgeons have to provide evidence-based interventions in life threatening conditions maintaining the ethical standards.

Research question

This narrative review sheds light on the current hindrances of the ethical aspects of neurosurgical practice in low and middle-income countries (LMICs) and provide some feasible solutions for future.

Material and methods

A literature search was conducted using PubMed, Scopus and ISI web of knowledge focused on articles in English with the words "medical ethics" together with the words "neurosurgery", "ethical practice", "low and middle-income countries", "surgical innovation", "randomized clinical trials" and "outcome" alone or in combination.

Results

Due to the lack of neurosurgeons and essential infrastructures in LMICs, the practical application of medical ethics is more complicated in the field of neurosurgery. Main obstacles to conduct preclinical and clinical research in the LMICs are the lack of proper ethics committees, quality data, trained manpower and sufficient research funding. Implementation of randomized clinical trials (RCTs) is also difficult for the neurosurgeons working in LMICs.

Discussion and conclusion

To improve the situation, socio-economic development, including educating the citizens of these countries about their rights, functional regulatory bodies like medical and dental councils, teaching the neurosurgeons about the internationally recognized medical ethics, quality control regulations by the ministry of health and welfare, and more funding for the health care sectors are urgently needed. Global collaboration is needed to help the LMICs to provide their patients international but "customized" standard care.

Prescribing sustainability: should UN sustainable development goals be part of the medical, pharmacy, and biomedical education?

Introduction

How to adapt the curriculum of medicine, pharmacy, and biomedical sciences to prepare future health professionals to meet the challenge of maintaining quality care in a period of socio-ecological crisis? Addressing connections between humanity and sustainable environment should include an analysis of the reciprocal influence of various ecosystems, since it is now clear that healthcare systems have an impact on ecosystems and vice versa. Here, we propose that integrating the United Nations Sustainable Development Goals (SDGs) into the curriculum could be a first step in such a transversal education.

Methods

Members of the faculty of medicine at the University of Namur, Belgium, including teaching staff of the department of medicine, pharmacy, biomedical sciences and psychology, were invited to respond anonymously to a questionnaire about their views on the feasibility of integrating the SDGs into their teaching. A subsequent survey on students' perceptions of such teaching was conducted by student representatives.

Results

Seventy-nine percent of surveyed members of the medical faculty believe that it is possible to integrate SDGs into their lectures. However, 44-86% of them did not know how to integrate each individual goal. 94.4% of students would like SDGs to play a greater role in their education; 64.4% of them would integrate them into existing modules; 23.9% would create an optional module, and 11.9% would create a mandatory module.

Conclusion

Sustainable Development Goals integration into the curriculum of medicine, pharmacy, and biomedical sciences is perceived as challenging in a dense teaching program. To clarify how SDGs can translate into traditional lectures, we provide for each SDG targeted applications for bachelor's, master's and continuing education.

Sleep-disordered breathing diagnosis: a comprehensive audit of home sleep testing in real clinical settings

PURPOSE

This study aimed to investigate the indications and outcomes of Home Sleep Testing (HST) for patients with suspected obstructive sleep apnea (OSA), aligning with guidelines set forth by the American Academy of Sleep Medicine and the European Sleep Research Society. Specifically, we aimed to audit whether validated type 3 polygraphy could effectively ensure patient care while optimizing resource utilization.

METHODS

A retrospective analysis was conducted on data from patients undergoing type 3 polygraphy for suspected OSA in a tertiary referral hospital between January 2022 and December 2022. Demographic, clinical, and management data were collected. The efficacy of HST in guiding management plans was evaluated, with outcomes categorized as effective or ineffective based on subsequent need for in-laboratory polysomnography.

RESULTS

While 85% of patients received a reliable diagnosis, 44.4% of them still required subsequent polysomnography, primarily due to adherence to funding regulations, rather than clinical need for further testing. Factors impacting the efficacy of HST included patient age, severity of apnea, and referral by a certified sleep specialist physician.

CONCLUSION

Our study highlighted the potential of type 3 polygraphy, as a valuable tool for diagnosing OSA in an outpatient setting. However, having the result interpreted by a certified sleep specialist doctor was not enough. To streamline the care pathway, the referral for polygraphy had also to be made by a trained specialist. Challenges related to funding regulations, patient demographics and physician training stress the need for optimized diagnostic pathways to improve patient care and resource utilization.

Understanding access to general practice through the lens of candidacy: a critical review of the literature

BACKGROUND

Dominant conceptualisations of access to health care are limited, framed in terms of speed and supply. The Candidacy Framework offers a more comprehensive approach, identifying diverse influences on how access is accomplished.

AIM

To characterise how the Candidacy Framework can explain access to general practice - an increasingly fraught area of public debate and policy.

DESIGN AND SETTING

Qualitative review guided by the principles of critical interpretive synthesis.

METHOD

We conducted a literature review using an author-led approach, involving iterative analytically guided searches. Articles were eligible for inclusion if they related to the context of general practice, without geographical or time limitations. Key themes relating to access to general practice were extracted and synthesised using the Candidacy Framework.

RESULTS

A total of 229 articles were included in the final synthesis. The seven features identified in the original Candidacy Framework are highly salient to general practice. Using the lens of candidacy demonstrates that access to general practice is subject to multiple influences that are highly dynamic, contingent, and subject to constant negotiation. These influences are socioeconomically and institutionally patterned, creating risks to access for some groups. This analysis enables understanding of the barriers to access that may exist, even though general practice in the UK is free at the point of care, but also demonstrates that a Candidacy Framework specific to this setting is needed.

CONCLUSION

The Candidacy Framework has considerable value as a way of understanding access to general practice, offering new insights for policy and practice. The original framework would benefit from further customisation for the distinctive setting of general practice.

Diminishing marginal returns and sufficiency in health-care resource use: an exploratory analysis of outcomes, expenditure, and emissions

BACKGROUND

Increasing health expenditure in low-income countries is associated with rapid gains in health status. Less attention has been paid to the possibility of diminishing marginal returns to health expenditure at high levels of spending, or to the relationship between health-care greenhouse gas emissions and outcomes. Our study aimed to investigate the existence, scale, and implications of diminishing marginal returns to health-care expenditure and emissions.

METHODS

Segmented (piecewise) regression analysis was used to explore the relationship between two measures of health outcome from the Global Burden of Disease project (mortality amenable to health care [MAH] and health-adjusted life expectancy [HALE]), four aggregates of health expenditure per capita from the WHO Global Health Expenditure Database, and health-care sector greenhouse gas emissions per capita derived from a 2020 study by Lenzen and colleagues. Turning point knots-points at which the elasticity or velocity of increasing returns to expenditure and emissions changed substantially-were estimated and countries in the vicinity of these knots identified.

FINDINGS

Rapidly increasing returns (improvements in population health as measured by MAH and HALE) to health expenditure were estimated in low-income and lower-middle-income countries; at levels of spending above approximately US$500 per capita, these returns start to slow. At levels of spending above those seen in high-income countries such as Italy (approximately US$3400), there is little or no evidence of further health returns to additional spending or to increasing health-care greenhouse gas emissions.

INTERPRETATION

Dramatic improvements in population health outcomes could be achieved by additional investment in health expenditure in low-income countries. Conversely, continuing growth in health expenditure in high-income countries will, by itself, be unlikely to yield rapid improvements in health outcomes. Our findings inform the emerging debate on the importance of sufficiency within planetary boundaries-low-income countries need rapid growth in health expenditure, whereas high-income countries could potentially achieve better health outcomes at substantially lower levels of resource use.

Optimizing the Management Algorithm for Heartburn in General Gastroenterology: Cost-Effectiveness and Cost-Minimization Analysis

BACKGROUND AND AIMS

Heartburn is the most common symptom seen in gastroenterology practice. We aimed to optimize cost-effective evaluation and management of heartburn.

METHODS

We developed a decision analytic model from insurer and patient perspectives comparing 4 strategies for patients failing empiric proton pump inhibitors (PPIs): (1) PPI optimization without testing, (2) endoscopy with PPI optimization for all patients, (3) endoscopy with PPI discontinuation when erosive findings are absent, and (4) endoscopy/ambulatory reflux monitoring with PPI discontinuation as appropriate for phenotypic management. Health outcomes were respectively defined on systematic reviews of clinical trials. Cost outcomes were defined on Centers for Medicare and Medicaid Services databases and commercial multipliers for direct healthcare costs, and national observational studies evaluating healthcare utilization. The time horizon was 1 year. All testing was performed off PPI.

RESULTS

PPI optimization without testing cost $3784/y to insurers and $3128 to patients due to lower work productivity and suboptimal symptom relief. Endoscopy with PPI optimization lowered insurer costs by $1020/y and added 11 healthy days/y by identifying erosive reflux disease. Endoscopy with PPI discontinuation added 11 additional healthy days/y by identifying patients without erosive reflux disease that did not need PPI. By optimizing phenotype-guided treatment, endoscopy/ambulatory reflux monitoring with a trial of PPI discontinuation was the most effective of all strategies (gaining 22 healthy days/y) and saved $2183 to insurers and $2396 to patients.

CONCLUSIONS

Among patients with heartburn, endoscopy with ambulatory reflux monitoring (off PPI) optimizes cost-effective management by matching treatment to phenotype. When erosive findings are absent, trialing PPI discontinuation is more cost-effective than optimizing PPI.

Measuring and improving the cradle-to-grave environmental performance of urological procedures

An urgent need for societal transformation exists to reduce the environmental impact of humanity, because environmental health affects human health. Health care causes ~5% of global greenhouse gas emissions and other substantial and ongoing environmental harms. Thus, health-care professionals and managers must lead ongoing efforts to improve the environmental performance of health systems. Life-cycle assessment (LCA) is a methodology that enables estimation of environmental impacts of products and processes. It models environmental effects from 'cradle' (raw material extraction) to 'grave' (end of useful life) and conventionally reports a range of different impact categories. LCA is a valuable tool when used appropriately. Maximizing its utility requires rational assumptions alongside careful consideration of system boundaries and data sources. Well-executed LCAs are detailed and transparently reported, enabling findings to be adapted or generalized to different settings. Attention should be given to modelling mitigation solutions in LCAs. This important step can guide health-care systems towards new and innovative solutions that embed progress towards international climate agreements. Many urological conditions are common, recurrent or chronic, requiring resource-intensive management with large associated environmental impacts. LCAs in urology have predominantly focussed on greenhouse gas emissions and have enabled identification of modifiable 'hotspots' including electricity use, travel, single-use items, irrigation, reprocessing and waste incineration. However, the methodological and reporting quality of published urology LCAs generally requires improvement and standardization. Health-care evaluation and commissioning frameworks that value LCA findings alongside clinical outcomes and cost could accelerate sustainable innovations. Rapid implementation strategies for known environmentally sustainable solutions are also needed.

Health Professionals' Views on the Use of Conversational Agents for Health Care: Qualitative Descriptive Study

BACKGROUND

In recent years, there has been an increase in the use of conversational agents for health promotion and service delivery. To date, health professionals' views on the use of this technology have received limited attention in the literature.

OBJECTIVE

The purpose of this study was to gain a better understanding of how health professionals view the use of conversational agents for health care.

METHODS

Physicians, nurses, and regulated mental health professionals were recruited using various web-based methods. Participants were interviewed individually using the Zoom (Zoom Video Communications, Inc) videoconferencing platform. Interview questions focused on the potential benefits and risks of using conversational agents for health care, as well as the best way to integrate conversational agents into the health care system. Interviews were transcribed verbatim and uploaded to NVivo (version 12; QSR International, Inc) for thematic analysis.

RESULTS

A total of 24 health professionals participated in the study (19 women, 5 men; mean age 42.75, SD 10.71 years). Participants said that the use of conversational agents for health care could have certain benefits, such as greater access to care for patients or clients and workload support for health professionals. They also discussed potential drawbacks, such as an added burden on health professionals (eg, program familiarization) and the limited capabilities of these programs. Participants said that conversational agents could be used for routine or basic tasks, such as screening and assessment, providing information and education, and supporting individuals between appointments. They also said that health professionals should have some oversight in terms of the development and implementation of these programs.

CONCLUSIONS

The results of this study provide insight into health professionals' views on the use of conversational agents for health care, particularly in terms of the benefits and drawbacks of these programs and how they should be integrated into the health care system. These collective findings offer useful information and guidance to stakeholders who have an interest in the development and implementation of this technology.

Diagnostic stewardship for blood cultures in the pediatric intensive care unit: lessons in implementation from the BrighT STAR Collaborative

Objective

BrighT STAR was a diagnostic stewardship collaborative of 14 pediatric intensive care units (PICUs) across the United States designed to standardize and reduce unnecessary blood cultures and study the impact on patient outcomes and broad-spectrum antibiotic use. We now examine the implementation process in detail to understand how sites facilitated this diagnostic stewardship program in their PICUs.

Design

A multi-center electronic survey of the 14 BrighT STAR sites, based on qualitative data about the implementation process collected during the primary phase of BrighT STAR.

Setting

14 PICUs enrolled in BrighT STAR.

Participants

Site leads at each enrolled site.

Methods

An electronic survey guided by implementation science literature and based on data collected during BrighT STAR was administered to all 14 sites after completion of the primary phase of the collaborative.

Results

10 specific tasks appear critical to implementing blood culture diagnostic stewardship, with variability in site-level strategies employed to accomplish those tasks. Sites rated certain tasks and strategies as highly important. Strategies used in top-performing sites were distinct from those used in lower-performing sites. Certain strategies may link to drivers of culture overuse and represent key targets for changing clinician behavior.

Conclusions

BrighT STAR offers important insights into the tasks and strategies used to facilitate successful diagnostic stewardship in the PICU. More work is needed to compare specific strategies and optimize stewardship outcomes in this complex environment.

General practitioners' risk literacy and real-world prescribing of potentially hazardous drugs: a cross-sectional study

BACKGROUND

Overuse of medical care is a pervasive problem. Studies using hypothetical scenarios suggest that physicians' risk literacy influences medical decisions; real-world correlations, however, are lacking. We sought to determine the association between physicians' risk literacy and their real-world prescriptions of potentially hazardous drugs, accounting for conflicts of interest and perceptions of benefit-harm ratios in low-value prescribing scenarios.

SETTING AND SAMPLE

Cross-sectional study-conducted online between June and October 2023 via field panels of Sermo (Hamburg, Germany)-with a convenience sample of 304 English general practitioners (GPs).

METHODS

GPs' survey responses on their treatment-related risk literacy, conflicts of interest and perceptions of the benefit-harm ratio in low-value prescribing scenarios were matched to their UK National Health Service records of prescribing volumes for antibiotics, opioids, gabapentin and benzodiazepines and analysed for differences.

RESULTS

204 GPs (67.1%) worked in practices with ≥6 practising GPs and 226 (76.0%) reported 10-39 years of experience. Compared with GPs demonstrating low risk literacy, GPs with high literacy prescribed fewer opioids (mean (M): 60.60 vs 43.88 prescribed volumes/1000 patients/6 months, p=0.016), less gabapentin (M: 23.84 vs 18.34 prescribed volumes/1000 patients/6 months, p=0.023), and fewer benzodiazepines (M: 17.23 vs 13.58 prescribed volumes/1000 patients/6 months, p=0.037), but comparable volumes of antibiotics (M: 48.84 vs 40.61 prescribed volumes/1000 patients/6 months, p=0.076). High-risk literacy was associated with lower conflicts of interest (ϕ = 0.12, p=0.031) and higher perception of harms outweighing benefits in low-value prescribing scenarios (p=0.007). Conflicts of interest and benefit-harm perceptions were not independently associated with prescribing behaviour (all ps >0.05).

CONCLUSIONS AND RELEVANCE

The observed association between GPs with higher risk literacy and the prescription of fewer hazardous drugs suggests the importance of risk literacy in enhancing patient safety and quality of care.

Health expenditure trajectory and gastric cancer incidence in the National Health Insurance Senior Cohort: a nested case-control study

BACKGROUND

Gastric cancer is the fourth most common cancer and highly prevalent in South Korea. As one of the predictors of gastric cancer, we focused on health utilization patterns and expenditures, as the surrogate variables of health conditions. This nested case-control study aimed to identify the association between health expenditure trajectory and incidence of gastric cancer.

METHODS

Data from the National Health Insurance Service Senior Cohort of South Korea were used. Individuals diagnosed with gastric cancer (N = 14,873) were matched to a non-diagnosed group (N = 44,619) in a 1:3 ratio using a nested case-control design. A latent class trajectory analysis was performed to identify the patterns of health expenditure among the matched participants. Furthermore, conditional logistic regression analysis was conducted to examine the relationship between healthcare expenditure trajectories and gastric cancer incidence.

RESULTS

Seven distinct health expenditure trajectories for five years were identified; consistently lowest (13.8%), rapidly increasing (5.9%), gradually increasing (13.8%), consistently second-highest (21.4%), middle-low (18.8%), gradually decreasing (13.1%), and consistently highest (13.2%). Compared to the middle-low group, individuals in the rapidly increasing [odds ratio (OR) = 2.11, 95% confidence interval (CI); 1.94-2.30], consistently lowest (OR = 1.40, 95% CI; 1.30-1.51), and gradually increasing (OR = 1.26, 95% CI; 1.17-1.35) groups exhibited a higher risk of developing gastric cancer.

CONCLUSIONS

Our findings suggest that health expenditure trajectories are predictors of gastric cancer. Potential risk groups can be identified by monitoring health expenditures.

Implementation of the WHO Standards to assess the quality of paediatric care using health workers as source of data: findings of a multicentre study (CHOICE) in Italy

OBJECTIVES

There is little experience in implementing the WHO Standards for improving the quality of care (QOC) for children. We describe the use of 75 WHO-Standard based Quality Measures to assess paediatric QOC, using health workers (HWs) as data sources.

DESIGN

Cross-sectional study.

SETTING

12 Italian hospitals.

PARTICIPANTS

The minimum target of 75% of HWs was reached in all facilities; answers from 598 HWs were analysed.

PRIMARY AND SECONDARY OUTCOME MEASURES

75 prioritised WHO Quality Measures were collected using a validated, and Italian-language questionnaire exploring views of HWs providing care to children. A QOC index was also calculated based on the assessed Quality Measures.

RESULTS

In both the domain of resources and work organisation, most Quality Measures showed a high overall frequency of reported 'need for improvement', with high variability across hospitals. Key needs for improvement included: availability of clear and complete protocols (eg, on paediatric emergencies: 44.6%; range 10.6%-92.6%); clear hospitalisation criteria for diarrhoea (50.5%; range 30.3%-71.7%); number of hand-washing stations (13.2%; range 3.4%-37.0%); equipped working rooms with computers for HWs (66.1%; range: 32.1%-97.0%); training (eg, on pain management: 43.5%; range 17.9%-76.7%), periodic discussion of clinical cases (43.5%; range 8.1%-83.7%) audits (48.8%; range 29.7%-76.7%); and all indicators related to system to improve QOC. Factors significantly associated with a lower QOC Index included HWs working in facilities in Southern Italy (p=0.001) and absence of a paediatric emergency department (p=0.011).

CONCLUSIONS

The use of the 75 prioritised Quality Measures, specific to HWs provide valuable data on paediatric QOC, which can be used to drive a quality improvement process.

When less is more: the art of communicating clinical microbiology results

The clinical microbiology laboratory is capable of identifying microorganisms in clinical specimens faster and more accurately than ever before. At face value, this should enable patient care providers to make better-informed decisions and target antimicrobial therapies to deliver individualized care. Ironically, more complete and specific reporting of microorganisms isolated from specimens may result in overtreatment based on the presence of a pathogen, even in the absence of clear signs of clinical infection. This conundrum calls into question the role of the laboratory in contributing to care through selective or "exception" reporting whereby some results are selectively withheld when there is a low probability that laboratory findings correlate with the clinical infection. In a recent article published in the Journal of Clinical Microbiology, Bloomfield et al. (J Clin Microbiol 62:e00342-24, 2024, https://doi.org/10.1128/jcm.00342-24) examine the impact and safety of an exception reporting strategy applied to wound swab specimens. Canonical pathogens associated with skin and soft tissue infections including S. aureus and beta-hemolytic streptococci are withheld from the laboratory report if certain patient criteria are met that would put them at low risk of adverse outcomes if untreated, or if treated with guideline-recommended empiric therapy. Their central finding was an approximately 50% reduction in post-laboratory report antibiotic initiation without adverse events or increased 30-day admission rate (indicative of infection-related complications, e.g., disseminated disease). While effectively achieving their goal, the premise of exception reporting and other modified reporting strategies raises questions about the potential risk of underreporting and how to ensure that the message is being interpreted, and acted upon, by care providers as was intended by the laboratory.

Effectiveness of de-implementation of low-value healthcare practices: an overview of systematic reviews

BACKGROUND

Reducing low-value care (LVC) is crucial to improve the quality of patient care while increasing the efficient use of scarce healthcare resources. Recently, strategies to de-implement LVC have been mapped against the Expert Recommendation for Implementing Change (ERIC) compilation of strategies. However, such strategies' effectiveness across different healthcare practices has not been addressed. This overview of systematic reviews aimed to investigate the effectiveness of de-implementation initiatives and specific ERIC strategy clusters.

METHODS

We searched MEDLINE (Ovid), Epistemonikos.org and Scopus (Elsevier) from 1 January 2010 to 17 April 2023 and used additional search strategies to identify relevant systematic reviews (SRs). Two reviewers independently screened abstracts and full texts against a priori-defined criteria, assessed the SR quality and extracted pre-specified data. We created harvest plots to display the results.

RESULTS

Of 46 included SRs, 27 focused on drug treatments, such as antibiotics or opioids, twelve on laboratory tests or diagnostic imaging and seven on other healthcare practices. In categorising de-implementation strategies, SR authors applied different techniques: creating self-developed strategies (n = 12), focussing on specific de-implementation strategies (n = 14) and using published taxonomies (n = 12). Overall, 15 SRs provided evidence for the effectiveness of de-implementation interventions to reduce antibiotic and opioid utilisation. Reduced utilisation, albeit inconsistently significant, was documented in the use of antipsychotics and benzodiazepines, as well as in laboratory tests and diagnostic imaging. Strategies within the adapt and tailor to context, develop stakeholder interrelationships, and change infrastructure and workflow ERIC clusters led to a consistent reduction in LVC practices.

CONCLUSION

De-implementation initiatives were effective in reducing medication usage, and inconsistent significant reductions were observed for LVC laboratory tests and imaging. Notably, de-implementation clusters such as change infrastructure and workflow and develop stakeholder interrelationships emerged as the most encouraging avenues. Additionally, we provided suggestions to enhance SR quality, emphasising adherence to guidelines for synthesising complex interventions, prioritising appropriateness of care outcomes, documenting the development process of de-implementation initiatives and ensuring consistent reporting of applied de-implementation strategies.

The conveyor belt for older people nearing the end of life

The current fallback position for the elderly frail nearing the end of life (less than 12 months to live) is hospitalisation. There is a reluctance to use the term 'terminally ill' for this population, resulting in overtreatment, overdiagnosis and management that is not consistent with the wishes of people. This is the major contributor to the so-called hospital crisis, including decreased capacity of hospitals, reduced ability to conduct elective surgery, increased attendances at emergency departments and ambulance ramping. The authors recently conducted the largest randomised study, to their knowledge, attempting to inform specialist hospital medical teams about the terminally ill status of their admitted patients. This information did not influence their clinical decisions in any way. The authors discuss the reasons why this may have occurred, such as the current avoidance of discussing death and dying by society and the concentration of healthcare workers on actively managing the acute presenting problem and ignoring the underlying prognosis in the elderly frail. The authors discuss ways of improving the management of the elderly nearing the end of life, such as more detailed goals of care discussions using the concept of shared decision-making rather than simply completing Advanced Care Decision documents. Empowering people in this way could become the most important driver of people's health care.
