Randomized Experiments to Reduce Overuse of Health Care: A Scoping Review.

OBJECTIVE: Health care overuse is pervasive in countries with advanced health care delivery systems. We hypothesize that effective interventions to reduce low-value care that targets patients or clinicians are mediated by psychological and cognitive processes that change behaviors and that interventions targeting these processes are varied. Thus, we performed a scoping review of experimental studies of interventions, including the interventions' objectives and characteristics, to reduce low-value care that targeted psychological and cognitive processes. METHODS: We systematically searched databases for experimental studies of interventions to change cognitive orientations and affective states in the setting of health care overuse. Outcomes included observed overuse or a stated intention to use services. We used existing frameworks for behavior change and mechanisms of change to categorize the interventions and the mediating processes. RESULTS: Twenty-seven articles met the inclusion criteria. Sixteen studied the provision of information to patients or clinicians, with most providing cost information. Six studies used educational interventions, including the provision of feedback about individual practice. Studies rarely used counseling, behavioral nudges, persuasion, and rewards. Mechanisms for behavior change included gain in knowledge or confidence and motivation by social norms. CONCLUSIONS: In this scoping review, we found few experiments testing interventions that directly target the psychological and cognitive processes of patients or clinicians to reduce low-value care. Most studies provided information to patients or clinicians without measuring or considering mediating factors toward behavior change. These findings highlight the need for process-driven experimental designs, including trials of behavioral nudges and persuasive language involving a trusting patient-clinician relationship, to identify effective interventions to reduce low-value care.

Sobreuso de ecografía transvaginal en un hospital universitario privado de Argentina: estudio de corte transversal / Transvaginal ultrasound overuse in a private university hospital in Argentina: a cross-sectional study

Introducción. Si bien contamos con recomendaciones basadas en la evidencia en contra de realizar tamizaje de cáncer ovárico con ecografía transvaginal debido a que aumenta el riesgo de resultados falsamente positivos y de cascadas diagnósticas, sin disminuir la mortalidad por esta enfermedad, su solicitud en mujeres sanas es frecuente. Sin embargo, no conocemos la magnitud de la implementación de esta práctica, que constituye un cuidado de bajo valor. Objetivo. Documentar el sobreuso de ecografías transvaginales realizadas en forma ambulatoria en un hospital universitario privado de Argentina. Métodos. Estudio de corte transversal de una muestra aleatoria de ecografías realizadas en forma ambulatoria durante 2017 y 2018. Mediante revisión manual de las historias clínicas, la solicitud de cada ecografía fue clasificada como apropiada cuando algún problema clínico justificaba su realización, o inapropiada cuando había sido realizada con fines de control de salud o por una condición clínica sin indicación de seguimiento ecográfico. Resultados. De un total de 1.997 ecografías analizadas, realizadas a 1.954 mujeres adultas (edad promedio 50 años),1.345 (67,4 %; intervalo de confianza [IC] 95 % 65,2 a 69,4) habían sido solicitadas en el contexto de un control de saludo sin un problema asociado en la historia clínica y otras 54 (8,3 %; IC 95 % 6,3 a 10,7), por condiciones de salud para las que no hay recomendaciones de realizar seguimiento ecográfico. Conclusiones. Esta investigación documentó una alta proporción de sobre utilización de la ecografías transvaginales en nuestra institución. Futuras investigaciones permitirán comprender los motivos que impulsan esta práctica y ayudarán a diseñar intervenciones para disminuir estos cuidados de bajo valor. (AU)

Background. Although we have evidence-based recommendations against screening for ovarian cancer with transvaginalultrasound because it increases the risk of false positive results and diagnostic cascades without reducing mortality from this disease, its request in healthy women is frequent. However, we do not know the magnitude of the implementation of this practice, which constitutes low-value care. Objective. To document the overuse of transvaginal ultrasounds performed on an outpatient basis in a private university hospital in Argentina. Methods. Cross-sectional study of a random sample of outpatient ultrasounds performed during 2017 and 2018. Through a manual review of the medical records, the request for each ultrasound was classified as appropriate when a clinical problem justified its performance or inappropriate when it was carried out for health control purposes or for a clinical condition that had no indication for ultrasound follow-up. Results. Of a total of 1997 ultrasounds analyzed, performed on 1954 adult women (average age 50 years), 1,345 (67.4 %;95 % confidence interval [CI] 65.2 to 69.4) had been requested in the context of a health check-up or without a documented problem in the medical history that would support its performance, and another 54 (8.3 %; 95 % CI 6.3 to 10.7), for health conditions for which there are no treatment recommendations to perform ultrasound follow-up. Conclusions. This research documented a high proportion of overuse of transvaginal ultrasound in our institution. Future research will allow us to understand the reasons that drive this practice and will help design interventions to reduce thislow-value care. (AU)

[What is overdiagnosis?] / Överdiagnostik ­ vad är det?

A considerable amount of spending in health care is deemed wasteful. Overdiagnosis, i.e. the labelling of a person with a diagnosis that lacks net benefit, is an entity within the overarching concept of ¼too much medicine«. Overdiagnosis includes overdetection and overdefinition. Disease mongering is a type of overdefinition with economic drivers. Overtesting and overtreatment are other aspects of ¼too much medicine«, but are not overdiagnosis per se. Medical research tends to focus on benefits of diagnostics and therapy, whereas overdiagnosis and other harms receive less attention, leading to overestimation of benefits. The international network Choosing Wisely has been successful in changing the diagnostic mindset in several countries and a Swedish campaign is under way, yielding new possibilities to counteract ¼too much medicine« and the specific problem of overdiagnosis.

Overuse of Tests and Treatments: Has Canada Made Progress?

Overuse of healthcare services is a complex issue. Also known as low-value care, these are tests, treatments and procedures that are commonly ordered despite clear evidence that they do not help with patient care and may even cause harm. National clinician societies have developed over 450 Choosing Wisely Canada (CWC) recommendations to spur conversation about what is appropriate and necessary treatment. The latest report from the Canadian Institute for Health Information and CWC measured the trends and variation in the use over time of tests and treatments related to 12 CWC recommendations (CIHI 2022). Reductions in overuse were observed in eight of the 12 tests and treatments examined; findings for two of these measures - chronic benzodiazepine use and red blood cell transfusions - are highlighted. Despite some progress on reducing overuse, there remains considerable room for improvement in the appropriate and judicious use of tests and treatments in Canada.

Reducing Overuse by Healthcare Systems: A Positive Deviance Analysis.

BACKGROUND: Healthcare in the USA is increasingly delivered by large healthcare systems that include one or more hospitals and associated outpatient practices. It is unclear what role healthcare systems play in driving or preventing overutilization of healthcare services in the USA. OBJECTIVE: To learn how high-value healthcare systems avoid overuse of services DESIGN: We identified "positive deviant" health systems using a previously constructed Overuse Index. These systems have much lower-than-average overuse of healthcare services. We confirmed that these health systems also delivered high-quality care. We conducted semi-structured interviews with executive leaders of these systems to validate a published framework for understanding drivers of overuse. PARTICIPANTS: Leaders at select healthcare systems in the USA. INTERVENTIONS: None APPROACH: We developed an interview guide and conducted semi-structured interviews. We iteratively developed a code book. Paired reviewers coded and reconciled each interview. We analyzed the interviews by applying constant comparative techniques. We mapped the emergent themes to provide the first empirical data to support a previously developed theoretical framework. KEY RESULTS: We interviewed 15 leaders from 10 diverse healthcare systems. Consistent with important domains from the overuse framework, themes from our study support the role of clinicians and patients in avoiding overuse. The leaders described how they create a culture of professional practice and how they modify clinicians' attitudes to facilitate high-value practices. They also described how their patients view healthcare consumption and the characteristics of their patient populations allowed them to practice high-value medicine. They described the role of quality metrics, insurance plan ownership, and alternative payment model participation as encouraging avoidance of overuse. CONCLUSIONS: Our qualitative analysis of positive deviant health systems supports the framework that is in the published literature, although health system leaders also described their financial structures as another important factor for reducing overuse and encouraging high-value care delivery.

Effect of an Individualized Audit and Feedback Intervention on Rates of Musculoskeletal Diagnostic Imaging Requests by Australian General Practitioners: A Randomized Clinical Trial.

Importance: Audit and feedback can improve professional practice, but few trials have evaluated its effectiveness in reducing potential overuse of musculoskeletal diagnostic imaging in general practice. Objective: To evaluate the effectiveness of audit and feedback for reducing musculoskeletal imaging by high-requesting Australian general practitioners (GPs). Design, Setting, and Participants: This factorial cluster-randomized clinical trial included 2271 general practices with at least 1 GP who was in the top 20% of referrers for 11 imaging tests (of the lumbosacral or cervical spine, shoulder, hip, knee, and ankle/hind foot) and for at least 4 individual tests between January and December 2018. Only high-requesting GPs within participating practices were included. The trial was conducted between November 2019 and May 2021, with final follow-up on May 8, 2021. Interventions: Eligible practices were randomized in a 1:1:1:1:1 ratio to 1 of 4 different individualized written audit and feedback interventions (n = 3055 GPs) that varied factorially by (1) frequency of feedback (once vs twice) and (2) visual display (standard vs enhanced display highlighting highly requested tests) or to a control condition of no intervention (n = 764 GPs). Participants were not masked. Main Outcomes and Measures: The primary outcome was the overall rate of requests for the 11 targeted imaging tests per 1000 patient consultations over 12 months, assessed using routinely collected administrative data. Primary analyses included all randomized GPs who had at least 1 patient consultation during the study period and were performed by statisticians masked to group allocation. Results: A total of 3819 high-requesting GPs from 2271 practices were randomized, and 3660 GPs (95.8%; n = 727 control, n = 2933 intervention) were included in the primary analysis. Audit and feedback led to a statistically significant reduction in the overall rate of imaging requests per 1000 consultations compared with control over 12 months (adjusted mean, 27.7 [95% CI, 27.5-28.0] vs 30.4 [95% CI, 29.8-30.9], respectively; adjusted mean difference, -2.66 [95% CI, -3.24 to -2.07]; P < .001). Conclusions and Relevance: Among Australian general practitioners known to frequently request musculoskeletal diagnostic imaging, an individualized audit and feedback intervention, compared with no intervention, significantly decreased the rate of targeted musculoskeletal imaging tests ordered over 12 months.

Too Much Healthcare: The Harmful Combination of Overdiagnosis and Medical Overuse, Told and Untold Stories.

BACKGROUND: Too much healthcare is prevalent, wasteful, and harmful. It consists of two separate phenomena: overdiagnosis and overuse. Overdiagnosis is the labeling of a person with a disease or abnormal condition that would not have caused the person harm if left undiscovered. Individuals derive no clinical benefit from overdiagnosis, although they may experience physical, psychological, or financial harm. It has been found that 15-30%, 20-50%, 0-67%, and 50-90% of people with screen detected breast, prostate, lung, and thyroid cancer, respectively, are overdiagnosed. Since many screening tests have trade-off between benefit and harm, a shared decision-making approach is essential. Incidental findings are very common and may also cause overdiagnosis. Overdiagnosis is recognizable in populations and not at the individual level. However, overuse is recognizable at the level of the individual practitioner. Choosing Wisely, an intervention directed at reducing low value care, now faces the challenge of developing interventions that go beyond recommendations. While some of the drivers of overdiagnosis and overuse are similar, different and parallel strategies are needed in order to reduce them. This is one of the major challenges to our health care system.

Predictors of Acute Care Transfers From Skilled Nursing Facilities: Recommendations for Preventing Unnecessary Hospitalization.

Preventing acute care transfers from skilled nursing facilities (SNFs) is a challenge secondary to residents' associated debilitated status and comorbidities. Acute care transfers often result in serious complications and unnecessary health care expenditure. Literature implies that approximately two thirds of these acute care transfers could be prevented using proactive interventions. The purpose of the current study was to identify the predictors of acute care transfers for SNF residents in developing relevant prevention strategies. A retrospective chart review using multivariate logistic regression analysis showed increased odds of SNF hospitalization was significantly associated with impaired cognition, chronic obstructive pulmonary disease, and chronic kidney disease, whereas decreased odds of hospitalization was identified among non-Hispanic White residents. Study recommendations include prompt assessment of comorbid symptomatology among SNF residents for the timely management and prevention of unnecessary acute care transfers.
