Protection against the overuse and underuse of health care - methodological considerations for establishing prioritization criteria and recommendations in general practice

Evaluation of the German living guideline "Protection against the Overuse and Underuse of Health Care" - an online survey among German GPs

BACKGROUND

The aim of this study was to evaluate the awareness and use of the German guideline "Protection against the overuse and underuse of health care" from the general practitioners' (GPs') perspective. In addition, the study assessed how GPs perceive medical overuse and what solutions they have for reducing it.

METHODS

We performed a cross-sectional online survey with recruitment from 15.06. to 31.07.2023. Participants were members of the German College of General Practitioners and Family Physicians (DEGAM). The main outcomes were the awareness and use of the guideline.

RESULTS

The analysis included data from 626 physicians. 51% were female and the median age was 50 years. The guideline is known by 81% of the participants, 32% read it in more detail. The majority considered the guideline a helpful tool in reducing overuse (67%). Almost 90% wished to have more guidelines with clear do-not-do recommendations. Physicians indicated in mean (M) that 30.2% (SD = 19.3%) of patients ask them for medical services that they do not consider to be necessary and that M = 30.2% (SD = 18.1%) of all GP services can be attributed to medical overuse. About half of the participants thought that overuse is a moderate or major problem in their practice (52%) and in general practice overall (58%). More participants rated that it is especially a problem in specialist (87%) and inpatient care (82%). Changes in the reimbursement system, raising awareness for the problem and more evidence-based guidelines were considered helpful in mitigating overuse.

CONCLUSIONS

Although the guideline is seen as a useful tool in mitigating medical overuse, there is still further potential for its implementation and utilisation. GPs see more overuse in the inpatient and outpatient specialist areas than in their area of practice. Instead of self-critically approaching the problem, the proposed strategies are aimed at the healthcare system itself.

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.

Cost-benefit analysis of the CoCare intervention to improve medical care in long-term care nursing homes: an analysis based on claims data

BACKGROUND

Providing adequate medical care to nursing home residents is challenging. Transfers to emergency departments are frequent, although often avoidable. We conducted the complex CoCare intervention with the aim to optimize nursing staff-physician collaboration to reduce avoidable hospital admissions and ambulance transportations, thereby reducing costs.

METHODS

This prospective, non-randomized study, based on German insurance data, includes residents in nursing homes. Health care cost from a payer perspective and cost-savings of such a complex intervention were investigated. The utilisation of services after implementation of the intervention was compared with services in previous quarters as well as services in the control group. To compensate for remaining differences in resident characteristics between intervention and control group, a propensity score was determined and adjusted for in the regression analyses.

RESULTS

The study population included 1240 residents in the intervention and 7552 in the control group. Total costs of medical services utilisation were reduced by €468.56 (p < 0.001) per resident and quarter in the intervention group. Hospital stays were reduced by 0.08 (p = 0.001) and patient transports by 0.19 (p = 0.049). This led to 1.66 (p < 0.001) avoided hospital days or €621.37 (p < 0.001) in costs-savings of inpatient services. More services were billed by general practitioners in the intervention group, which led to additional costs of €97.89 (p < 0.001).

CONCLUSION

The benefits of our intervention clearly exceed its costs. In the intervention group, avoided hospital admissions led to additional outpatient billing. This indicates that such a multifactorial intervention program can be cost-saving and improve medical care in long-term care homes.

Geographical variation in compulsory hospitalisation - ethical challenges

BACKGROUND

Compulsory hospitalisation in mental health care restricts patients' liberty and is experienced as harmful by many. Such hospitalisations continue to be used due to their assumed benefit, despite limited scientific evidence. Observed geographical variation in compulsory hospitalisation raises concern that rates are higher and lower than necessary in some areas.

METHODS/DISCUSSION

We present a specific normative ethical analysis of how geographical variation in compulsory hospitalisation challenges four core principles of health care ethics. We then consider the theoretical possibility of a "right", or appropriate, level of compulsory hospitalisation, as a general norm for assessing the moral divergence, i.e., too little, or too much. Finally, we discuss implications of our analysis and how they can inform the future direction of mental health services.

Guideline Adherence As An Indicator of the Extent of Antithrombotic Overuse and Underuse: A Systematic Review

Thromboembolic events are a common risk in adults with atrial fibrillation, those with previous cerebrovascular accidents and undergoing emergency or elective surgeries. The widespread availability of antithrombotic agents and differing guidelines contribute to practice variations and increased risk of complications and deaths. The objective of this review was to investigate the extent of overuse and underuse of antithrombotics for primary or secondary prevention as measured by deviation from prescribing guideline recommendations. We conducted a systematic review of Medline and EMBASE for quantitative articles published between 2000 and 2021 and used a modified version of the Hoy’s risk of bias assessment tool. Here we report evidence from the past decade about wide practice variations in hospitals and primary care, and discuss clinician and patient-driven determinants of non-adherence to guidelines. Finally, we summarise implications for practice, identify enhanced ways of measuring overuse and underuse, and propose potential solutions to the measurement challenges.

Medical Practice Variation Among Primary Care Physicians: 1 Decade, 14 Health Services, and 3,238,498 Patient-Years

PURPOSE

Variation in medical practice is associated with poorer health outcomes, increased costs, disparities in care, and increased burden on the public health system. In the present study, we sought to describe and assess inter- and intra-primary care physician variation, adjusted for patient and clinic characteristics, over a decade of practice and across a broad range of health services.

METHODS

We assessed practice patterns of 251 primary care physicians in southern Israel. For each of 14 health services (imaging tests, cardiac tests, laboratory tests, and specialist visits) we described interphysician and intraphysician variation, adjusted for patient case mix and clinic characteristics, using the coefficient of variation. The adjusted rates were assessed by generalized linear negative-binomial mixed models.

RESULTS

The variation between physicians was on average 3-fold greater than the variation of individual physician practice over the years. Services with low utilization were associated with greater inter- and intraphysician variation: r_s = (-0.58), P = .03 and r_s = (-0.39), P = .17, respectively. In addition, physician utilization ranks averaged over all health services were consistent across the 14 health services (intraclass correlation coefficient, 0.94; 95% CI, 0.93-0.95).

CONCLUSIONS

Our results show greater variation in practice patterns between physicians than for individual physicians over the years. It appears that the variation remains high even after adjustment for patient and clinic characteristics and that the individual physician utilization patterns are stable across health services. We propose that personal behavioral characteristics of medical practitioners might explain this variation.

Limiting surveillance imaging for patients with lymphoma in remission: a mixed methods study leading to a Choosing Wisely recommendation

BACKGROUND

Under the 'Choosing Wisely' (CW) framework, professional organisations internationally have advocated limiting imaging for asymptomatic patients following curative cancer therapy, based on limited value and high cost. F18-fluorodeoxyglucose (FDG) positron emission tomography-CT (PET/CT) was widely adopted locally for surveillance lymphoma imaging after 2004.

OBJECTIVES

Prior to ratification of a local CW recommendation to limit surveillance imaging in lymphoma, we aimed to assess: (A) performance characteristics of surveillance FDG-PET/CT; (B) rates, clinical consequences and costs of false positives (FP); and (C) patients and professionals' attitudes towards overuse.

METHODS

Mixed methods (quantitative and qualitative) study. We analysed surveillance FDG-PET/CT results of two patient cohorts (n1=215 Hodgkin lymphoma and non-Hodgkin lymphoma; n2=203 Hodgkin lymphoma only). FPs were defined by negative biopsy or clinical follow-up. We held focus group discussions and in-depth interviews eliciting attitudes of 26 patients and 11 clinicians, respectively.

RESULTS

FPs were observed in 25.1% (95% CI 20.5 to 30.5) per scan-cohort 1, and 41.7% (95% CI 37.9 to 45.6) per patient-cohort 2, engendering frequent additional testing. Specific characteristics and location of findings altered the FP rate. The estimated cost per relapse detected was $50 000 (cohort 2). Patients sought reassurance via surveillance imaging, which they considered highly accurate, yet stressful. Aware of radiation risks, they were largely unconcerned about consequences of FPs. Confidence in the treating physicians was an important factor in patients' acceptance of forgoing imaging. Clinicians, frequently under patient pressure to order imaging, generally believed that it did not affect prognosis (with important exceptions), welcomed professional guidelines, but rejected regulatory restrictions on its use.

CONCLUSION

Acceptance of CW recommendations to limit overuse may be enhanced by quantitative data on consequences and costs of surveillance imaging, supplemented by qualitative data on patient and physician attitudes.

Assessing the appropriateness of paediatric antibiotic overuse in Australian children: a population-based sample survey

Background

Infections caused by antibiotic resistant pathogens are increasing, with antibiotic overuse a key contributing factor.

Objective

The CareTrack Kids (CTK) team assessed the care of children in Australia aged 0–15 years in 2012 and 2013 to determine the proportion of care in line with clinical practice guidelines (CPGs) for 17 common conditions. This study analyses indicators relating to paediatric antibiotic overuse to identify those which should be prioritised by antimicrobial stewardship and clinical improvement programs.

Method

A systematic search was undertaken for national and international CPGs relevant to 17 target conditions for Australian paediatric care in 2012–2013. Recommendations were screened and ratified by reviewers. The sampling frame comprised three states containing 60% of the Australian paediatric population (South Australia, New South Wales and Queensland). Multi-stage cluster sampling was used to select general practices, specialist paediatric practices, emergency departments and hospital inpatient services, and medical records within these. Medical records were reviewed by experienced paediatric nurses, trained to assess eligibility for indicator assessment and compliance with indicators. Adherence rates were estimated.

Results

Ten antibiotic overuse indicators were identified; three for tonsillitis and one each for seven other conditions. A total of 2621 children were assessed. Estimated adherence for indicators ranged from 13.8 to 99.5% while the overall estimate of compliance was 61.9% (95% CI: 47.8–74.7). Conditions with high levels of appropriate avoidance of antibiotics were gastroenteritis and atopic eczema without signs of infection, bronchiolitis and croup. Indicators with less than 50% adherence were asthma exacerbation in children aged > 2 years (47.1%; 95% CI: 33.4–61.1), sore throat with no other signs of tonsillitis (40.9%; 95% CI: 16.9, 68.6), acute otitis media in children aged > 12 months who were mildly unwell (13.8%; 95% CI: 5.1, 28.0), and sore throat and associated cough in children aged < 4 years (14.3%; 95% CI: 9.9, 19.7).

Conclusion

The results of this study identify four candidate indicators (two for tonsillitis, one for otitis media and one for asthma) for monitoring by antibiotic stewardship and clinical improvement programs in ambulatory and hospital paediatric care, and intervention if needed.

Defining when specialised mental health care is needed: a focus group study

BACKGROUND

Shared understanding between GPs and hospital specialists concerning when patients need specialised mental health care is important to ensure patients receive appropriate care. The large amount of rejected referrals often indicates a lack of such shared understanding.

AIM

To explore how patient representatives, GPs, and mental health specialists understand 'need for specialised mental health care', meaning that primary care is no longer sufficient.

DESIGN & SETTING

This qualitative study was conducted in western Norway. The study has a service user-involved research design in which GPs and patient representatives participated in all stages of the research process.

METHOD

Six semi-structured focus group interviews were conducted. The groups were homogenous as they included only the perspectives of either GPs, mental health specialists, or patient representatives. Data were analysed using thematic analysis.

RESULTS

The need for specialised mental health care was assessed using two continuums: (a) the patient's level of functioning and symptoms; and (b) characteristics of the healthcare system and the patient's informal support networks. Assessment along these continuums were often overruled by the evaluation of expected usefulness of specialised mental health care. In addition, all participants reported they often adapted their definition of need to fit other stakeholders' interpretations of need.

CONCLUSION

Evaluation of need for specialised mental health care is complex and depends on several factors. This may explain some of the current challenges that exist with regard to equity and timely access to appropriate healthcare interventions.
