A Practical Framework for Understanding and Reducing Medical Overuse: Conceptualizing Overuse Through the Patient-Clinician Interaction

[Outcome of complaints by patients due to the refusal of Primary Care Physicians to agree to a treatment request]

OBJECTIVE

To analyse the frequency of complaints due to the refusal of Primary Care Physicians to indicate a diagnostic test, treatment, or referral requested by a patient.

METHODS

Observational, retrospective study was conducted by analysing the complaints filed in a Primary Care Area during the years 2016, 2017, and 2018.

RESULTS

A total of 378 complaints were included. Of these, 30 (8%) were justified in the refusal by the doctors to a request of the patient (28 addressed to general practitioners and 2 to paediatricians). The most frequent related to the request was for a treatment (18 [60%]) followed by the request for diagnostic tests (9 [30%]). While the total number of claims increased by 151%, the relative weight of the claims for not responding to a patient's request was reduced (2016, 8/70, 11.4%; 2017, 11/132, 8.3%; and 2018, 11/176, 6.3%). No professional liability claims were filed.

CONCLUSIONS

Complaints for rejecting patient requests increased slightly, but tends to decrease their relative weight when considering the volume of complaints.

Unpacking the complexities of de-implementing inappropriate health interventions

De-implementing inappropriate health interventions is essential for minimizing patient harm, maximizing efficient use of resources, and improving population health. Research on de-implementation has expanded in recent years as it cuts across types of interventions, patient populations, health conditions, and delivery settings. This commentary explores unique aspects of de-implementing inappropriate interventions that differentiate it from implementing evidence-based interventions, including multi-level factors, types of action, strategies for de-implementation, outcomes, and unintended negative consequences. We highlight opportunities to continue to advance research on the de-implementation of inappropriate interventions in health care and public health.

General practitioners referring patients to specialists in tertiary healthcare: a qualitative study

BACKGROUND

There is a large and unexplained variation in referral rates to specialists by general practitioners, which calls for investigations regarding general practitioners' perceptions and expectations during the referral process. Our objective was to describe the decision-making process underlying referral of patients to specialists by general practitioners working in a university outpatient primary care center.

METHODS

Two focus groups were conducted among general practitioners (10 residents and 8 chief residents) working in the Center for Primary Care and Public Health (Unisanté) of the University of Lausanne, in Switzerland. Focus group data were analyzed with thematic content analysis. A feedback group of general practitioners validated the results.

RESULTS

Participating general practitioners distinguished two kinds of situations regarding referral: a) "clear-cut situations", in which the decision to refer or not seems obvious and b) "complex cases", in which they hesitate to refer or not. Regarding the "complex cases", they reported various types of concerns: a) about the treatment, b) about the patient and the doctor-patient relationship and c) about themselves. General practitioners evoked numerous reasons for referring, including non-medical factors such as influencing patients' emotions, earning specialists' esteem or sharing responsibility. They also explained that they seek validation by colleagues and postpone referral so as to relieve some of the decision-related distress.

CONCLUSIONS

General practitioners' referral of patients to specialists cannot be explained in biomedical terms only. It seems necessary to take into account the fact that referral is a sensitive topic for general practitioners, involving emotionally charged interactions and relationships with patients, colleagues, specialists and supervisors. The decision to refer or not is influenced by multiple contextual, personal and clinical factors that dynamically interact and shape the decision-making process.

Low-value clinical practices and harm caused by non-adherence to 'do not do' recommendations in primary care in Spain: a Delphi study

OBJECTIVE

To determine the non-adherence to the primary care 'do not do' recommendations (DNDs) and their likelihood to cause harm.

DESIGN

Delphi study.

SETTING

Spanish National Health System.

PARTICIPANTS

A total of 128 professionals were recruited (50 general practitioners [GPs], 28 pediatricians [PEDs], 31 nurses who care for adult patients [RNs] and 19 pediatric nurses [PNs]).

INTERVENTIONS

A selection of 27 DNDs directed at GPs, 8 at PEDs, 9 at RNs and 4 at PNs were included in the Delphi technique. A 10-point scale was used to assess whether a given practice was still present and the likelihood of it causing of an adverse event.

MAIN OUTCOME MEASURE

Impact calculated by multiplying an event's frequency and likelihood to cause harm.

RESULTS

A total of 100 professionals responded to wave 1 (78% response rate) and 97 of them to wave 2 (97% response rate). In all, 22% (6/27) of the practices for GPs, 12% (1/8) for PEDs, 33% (3/9) for RNs and none for PNs were cataloged as frequent. A total of 37% (10/27) of these practices for GPs, 25% (2/8) for PEDs, 33% (3/9) for RNs and 25% (1/4) for PNs were considered as potential causes of harm. Only 26% (7/27) of the DNDs for GPs showed scores equal to or higher than 36 points. The impact measure was higher for ordering benzodiazepines to treat insomnia, agitation or delirium in elderly patients (mean = 57.8, SD = 25.3).

CONCLUSIONS

Low-value and potentially dangerous practices were identified; avoiding these could improve care quality.

Imprinting on Clinical Rotations: Multisite Survey of High- and Low-Value Medical Student Behaviors and Relationship with Healthcare Intensity

BACKGROUND

Physician behaviors are important to high-value care, and the learning environment medical students encounter on clinical clerkships may imprint their developing practice patterns.

OBJECTIVES

To explore potential imprinting on clinical rotations by (a) describing high- and low-value behaviors among medical students and (b) examining relationships with regional healthcare intensity (HCI).

DESIGN

Multisite cross-sectional survey PARTICIPANTS: Third- and fourth-year students at nine US medical schools MAIN MEASURES: Survey items measured high-value (n = 10) and low-value (n = 9) student behaviors. Regional HCI was measured using Dartmouth Atlas End-of-Life Chronic Illness Care data (ratio of physician visits per decedent compared with the US average, hospital care intensity index, ratio of medical specialty to primary care physician visits per decedent). Associations between regional HCI and student behaviors were examined using unadjusted and adjusted (controlling for age, sex, and year in school) logistic regression analyses, using median item ratings to summarize reported engagement in high- and low-value behaviors.

KEY RESULTS

Of 2623 students invited, 1304 (50%) responded. Many reported trying to determine healthcare costs (1085/1234, 88%), but only 45% (571/1257) reported including cost details in case presentations. Students acknowledged suggesting tests solely to anticipate what their supervisor would want (1143/1220, 94%), show off their ability to generate a broad differential diagnosis (1072/1218, 88%), satisfy curiosity (958/1217, 79%), protect the team from liability (938/1215, 77%), and build clinical experience (533/1217, 44%). Students in higher intensity regions reported significantly more low-value behaviors: each one-unit increase in the ratio of physician visits per decedent increased the odds of reporting low-value behaviors by 20% (OR 1.20, 95% CI 1.04-1.38; P = 0.01).

CONCLUSIONS

Third- and fourth-year medical students report engaging in both high- and low-value behaviors, which are related to regional HCI. This underscores the importance of the clinical learning environment and suggests imprinting is already underway during medical school.

Evaluation of an Intervention to Reduce Low-Value Preoperative Care for Patients Undergoing Cataract Surgery at a Safety-Net Health System

IMPORTANCE

Preoperative testing for cataract surgery epitomizes low-value care and still occurs frequently, even at one of the nation's largest safety-net health systems.

OBJECTIVE

To evaluate a multipronged intervention to reduce low-value preoperative care for patients undergoing cataract surgery and analyze costs from various fiscal perspectives.

DESIGN, SETTING, AND PARTICIPANTS

This study took place at 2 academic safety-net medical centers, Los Angeles County and University of Southern California (LAC-USC) (intervention, n = 469) and Harbor-UCLA (University of California, Los Angeles) (control, n = 585), from April 13, 2015, through April 12, 2016, with 12 additional months (April 13, 2016, through April 13, 2017) to assess sustainability (intervention, n = 1002; control, n = 511). To compare pre- and postintervention vs control group utilization and cost changes, logistic regression assessing time-by-group interactions was used.

INTERVENTIONS

Using plan-do-study-act cycles, a quality improvement nurse reviewed medical records and engaged the anesthesiology and ophthalmology chiefs with data on overuse; all 3 educated staff and trainees on reducing routine preoperative care.

MAIN OUTCOMES AND MEASURES

Percentage of patients undergoing cataract surgery with preoperative medical visits, chest x-rays, laboratory tests, and electrocardiograms. Costs were estimated from LAC-USC's financially capitated perspective, and costs were simulated from fee-for-service (FFS) health system and societal perspectives.

RESULTS

Of 1054 patients, 546 (51.8%) were female (mean [SD] age, 60.6 [11.1] years). Preoperative visits decreased from 93% to 24% in the intervention group and increased from 89% to 91% in the control group (between-group difference, -71%; 95% CI, -80% to -62%). Chest x-rays decreased from 90% to 24% in the intervention group and increased from 75% to 83% in the control group (between-group difference, -75%; 95% CI, -86% to -65%). Laboratory tests decreased from 92% to 37% in the intervention group and decreased from 98% to 97% in the control group (between-group difference, -56%; 95% CI, -64% to -48%). Electrocardiograms decreased from 95% to 29% in the intervention group and increased from 86% to 94% in the control group (between-group difference, -74%; 95% CI, -83% to -65%). During 12-month follow-up, visits increased in the intervention group to 67%, but chest x-rays (12%), laboratory tests (28%), and electrocardiograms (11%) remained low (P < .001 for all time-group interactions in both periods). At LAC-USC, losses of $42 241 in year 1 were attributable to intervention costs, and 3-year projections estimated $67 241 in savings. In a simulation of a FFS health system at 3 years, $88 151 in losses were estimated, and for societal 3-year perspectives, $217 322 in savings were estimated.

CONCLUSIONS AND RELEVANCE

This intervention was associated with sustained reductions in low-value preoperative testing among patients undergoing cataract surgery and modest cost savings for the health system. The findings suggest that reducing low-value care may be associated with cost savings for financially capitated health systems and society but also with losses for FFS health systems, highlighting a potential barrier to eliminating low-value care.

Attitudes toward cost-conscious care among U.S. physicians and medical students: analysis of national cross-sectional survey data by age and stage of training

BACKGROUND

The success of initiatives intended to increase the value of health care depends, in part, on the degree to which cost-conscious care is endorsed by current and future physicians. This study aimed to first analyze attitudes of U.S. physicians by age and then compare the attitudes of physicians and medical students.

METHODS

A paper survey was mailed in mid-2012 to 3897 practicing physicians randomly selected from the American Medical Association Masterfile. An electronic survey was sent in early 2015 to all 5,992 students at 10 U.S. medical schools. Survey items measured attitudes toward cost-conscious care and perceived responsibility for reducing healthcare costs. Physician responses were first compared across age groups (30-40 years, 41-50 years, 51-60 years, and > 60 years) and then compared to student responses using Chi square tests and logistic regression analyses (controlling for sex).

RESULTS

A total of 2,556 physicians (65%) and 3395 students (57%) responded. Physician attitudes generally did not differ by age, but differed significantly from those of students. Specifically, students were more likely than physicians to agree that cost to society should be important in treatment decisions (p < 0.001) and that physicians should sometimes deny beneficial but costly services (p < 0.001). Students were less likely to agree that it is unfair to ask physicians to be cost-conscious while prioritizing patient welfare (p < 0.001). Compared to physicians, students assigned more responsibility for reducing healthcare costs to hospitals and health systems (p < 0.001) and less responsibility to lawyers (p < 0.001) and patients (p < 0.001). Nearly all significant differences persisted after controlling for sex and when only the youngest physicians were compared to students.

CONCLUSIONS

Physician attitudes toward cost-conscious care are similar across age groups. However, physician attitudes differ significantly from medical students, even among the youngest physicians most proximate to students in age. Medical student responses suggest they are more accepting of cost-conscious care than physicians and attribute more responsibility for reducing costs to organizations and systems rather than individuals. This may be due to the combined effects of generational differences, new medical school curricula, students' relative inexperience providing cost-conscious care within complex healthcare systems, and the rapidly evolving U.S. healthcare system.

Development of a Conceptual Map of Negative Consequences for Patients of Overuse of Medical Tests and Treatments

IMPORTANCE

Overuse of medical tests and treatments is an increasingly recognized problem across health systems; best practices for reducing overuse are not clear. Framing the problem in terms of the spectrum of potential patient harm is likely to be an effective strategy for clinician and patient engagement in efforts to reduce overuse, but the scope of negative consequences of overuse for patients has not been well described.

OBSERVATIONS

We sought to generate a comprehensive conceptual map documenting the processes through which overused tests and treatments lead to multiple domains of negative consequences for patients. For map development, an iterative consensus process was informed by structured review of the literature on overuse using PubMed and input from a panel of 6 international experts. For map verification, a systematic review was performed of case reports involving overused services, identified through literature review and manual review of relevant article collections. The conceptual map documents that overused tests and treatments and resultant downstream services generate 6 domains of negative consequences for patients: physical, psychological, social, financial, treatment burden, and dissatisfaction with health care. Negative consequences can result from overused services and from downstream services; they can also trigger further downstream services that in turn can lead to more negative consequences, in an ongoing feedback loop. Case reports on overuse confirmed the processes and domains of the conceptual map. Cases also revealed strengths and weaknesses in published communication about overuse: they were dominated by physical harms, with other negative consequences receiving far less attention.

CONCLUSIONS AND RELEVANCE

This evidence-based conceptual map clarifies the processes by which overused tests and treatments result in negative consequences for patients; it also documents multiple domains of negative consequences experienced by patients. The map will be useful for facilitating comprehensive communication about overuse, estimating harms and costs associated with overused services, and informing health system efforts to reduce overuse.

Taking societal cost into clinical consideration: U.S. physicians' views

BACKGROUND

Recent campaigns (e.g., the American Board of Internal Medicine Foundation's Choosing Wisely) reflect the increasing role that physicians are expected to have in stewarding health care resources. We examine whether physicians believe they should pay attention to societal costs or refuse requests for costly interventions with little chance of patient benefit.

METHODS

We conducted a secondary analysis of data from a 2010 national survey of 2016 U.S. physicians sampled from the AMA Physician Masterfile. Criterion measures were agreement or disagreement with two survey items related to costs of care. We also examined whether physicians' practice and religious characteristics were associated with their responses.

RESULTS

The adjusted response rate was 62% (1156/1878). Forty-seven percent of physicians agreed that physicians "should not consider the societal cost of medical care when caring for individual patients," whereas 69% agreed that physicians "should refuse requests from patients or their families for costly interventions that have little chance of benefitting the patient." Physicians in specialties that care for patients at the end of life were more supportive of refusing such costly interventions. We did not find consistent associations between physicians' religiosity and their responses to these items, though those least supportive of taking into account societal cost were disproportionately from Christian affiliations.

CONCLUSION

Physicians were nearly evenly divided regarding whether they should help control societal costs when caring for individual patients, but a strong majority agreed that physicians should refuse costly interventions that have little chance of benefit.

Medical overuse in the Iranian healthcare system: a systematic review protocol

INTRODUCTION

Lack of resources is one of the main problems of all healthcare systems. Recent studies have shown that reducing the overuse of medical services plays an important role in reducing healthcare system costs. Overuse of medical services is a major problem in the healthcare system, and it threatens the quality of the services, can harm patients and create excess costs for patients. So far, few studies have been conducted in this regard in Iran. The main objective of this systematic review is to perform an inclusive search for studies that report overuse of medical services in the Iranian healthcare system.

METHOD AND ANALYSIS

An extensive search of the literature will be conducted in six databases including PubMed, Embase, Scopus, Web of Science, Cochrane and Scientific Information Database using a comprehensive search strategy to identify studies on overuse of medical care. The search will be done without time limit until the end of 2017, completed by reference tracking, author tracking and expert consultation. The search will be conducted on 1 February 2018. Any study that reports an overuse in a service based on a specific standard will be included in the study. Two reviewers will screen the articles based on the title, abstract and full text, and extract data about type of service, clinical area and overuse rate. Quality appraisal will be assessed using the Joanna Briggs Institute checklist. Potential discrepancies will be resolved by consulting a third author.

ETHICS AND DISSEMINATION

Recommendations will be made to the Iranian MOHME (Ministry of Health and Medical Education) in order to make better evidence-based decisions about medical services in the future.

[The Choosing Wisely Initiative (CWI): Background, aims and problems of a professional campaign against oversupply]

The Choosing Wisely Initiative (CWI) started in 2012 follows a proposal by Howard Brody (2010). Using CWI, the US ABIM Foundation continued its work to strengthen medical professionalism. The text describes CWI's development, aims, mission, and dissemination. It discusses some of its limits and problems. An appendix tabulates similarities and differences between CWI and a (2016) subsequent initiative from the German Society of Internal Medicine (DGIM: Klug Entscheiden Empfehlungen/decide wisely recommendations).
