Barriers and facilitators for the management of vertigo: a qualitative study with primary care providers

Barriers and facilitators of adherence to clinical practice guidelines in Germany-A systematic review

RATIONALE

Clinical Practice Guidelines (CPGs) represent evidence-based tools designed to assist healthcare practitioners and patients in decisions in clinical practice. Evidence supports the clinical benefits of adhering to CPGs. However, their successful implementation and adherence in clinical settings often encounter challenges.

AIMS AND OBJECTIVES

This systematic review aimed to explore barriers and facilitators influencing adherence to CPGs in Germany.

METHOD

The protocol of this study was registered in the Open Science Framework (OSF) registry (DOI: 10.17605/OSF. IO/GMFUB). In November 2022 we searched on PubMed and Embase for primary studies employing qualitative, quantitative and mixed-methods approaches that focus on barriers or facilitators to CPGs adherence in the Germany. Two reviewers independently screened articles, extracted data, and evaluated the quality of the studies. The collected data on barriers and facilitators of CPG adherence were systematically categorized and analyzed using the Theoretical Domains Framework (TDF).

RESULTS

A total of 24 studies were included, mainly focusing on adherence to national CPGs. This review introduces a new domain, guideline characteristics, reflecting the need to address barriers and facilitators to CPG development, implementation, dissemination and format, which couldn't be encompassed within the existing 14 domains of TDF framework. Among healthcare professionals, the most frequently reported influencing factors were related to the environmental context and resources (encompassing aspects such as employer support for CPG utilization), the CPG development and dissemination process (including layout, wording, and interactive tools) and beliefs about consequences (such as contradictions with practical experience). Knowledge (knowledge about the content of CPGs, awareness about published CPGs), primarily as a barrier, and reinforcement facilitators (notably financial support), were also frequently reported.

CONCLUSION

The findings revealed multilevel factors contributing to CPG adherence, with environmental context and resources emerging as the most frequently reported considerations. This systematic review offer holistic insights into the barriers and facilitators of CPG adherence in Germany. The results contribute to a better understanding of the topic and serve as a resource for developing targeted strategies to enhance CPG adherence and implementation within the German healthcare system.

Patients' Needs Regarding Work-Focused Healthcare: A Qualitative Evidence Synthesis

PURPOSE

To identify, appraise, and synthesize qualitative research evidence exploring patients' needs regarding work-focused healthcare.

METHODS

A systematic review was conducted in accordance with the PRISMA statement guidelines to identify studies reporting patients' needs regarding work-focused healthcare. Four databases (MEDLINE, Embase, PsychInfo and Web of Science) were systematically searched from January 2000 until May 2023 and screened in duplicate by pairs of two reviewers. Inclusion criteria were qualitative data collection method, and patients' perspectives regarding healthcare focusing on work when experiencing work-related problems due to chronic medical conditions. Data extraction and synthesis was executed by means of an inductive thematic analysis approach. The quality of the included studies was assessed using the CASP Qualitative Study checklist. Confidence in the review findings was assessed through the Confidence in the Evidence from Reviews of Qualitative research (CERQual) approach.

RESULTS

Out of 23,677 records, 97 qualitative studies were included. Needs regarding four main themes were identified: (1) Substantive guidance, which comprises the specific content of work-focused healthcare; (2) Clear and continuous process, which comprises clarification and optimization of the work-focused healthcare process; (3) Supportive attitude and behavior, which comprises a positive and supportive attitude and behavior from professionals towards the patients; and (4) Tailored approach, which comprises the delivery of tailored care to the individuals' needs. 17 subthemes were identified.

CONCLUSION

The broader insight in patients' needs in work-focused healthcare can help (occupational) healthcare professionals adopt a more patient-centred approach in practice.

Tools for assessing the methodological limitations of a QES-a short note

The increasing prevalence and application of qualitative evidence syntheses (QES) in decision-making processes underscore the need for robust tools to assess the methodological limitations of a completed QES. This commentary discusses the limitations of three existing tools and presents the authors' efforts to address this gap. Through a simple comparative analysis, the three tools are examined in terms of their coverage of essential topic areas. The examination finds that existing assessment tools lack comprehensive coverage, clarity, and grounding in qualitative research principles. The authors advocate for the development of a new collaboratively developed evidence-based tool rooted in qualitative methodology and best practice methods. The conclusion emphasizes the necessity of a tool that can provide a comprehensive judgement on the methodological limitations of a QES, addressing the needs of end-users, and ultimately enhancing the trustworthiness of QES findings in decision-making processes.

Study protocol for a nationwide implementation of internet-based vestibular rehabilitation for patients with chronic vestibular symptoms (I-RECOVER)

BACKGROUND

Vestibular rehabilitation is a safe and effective exercise-based treatment for patients with chronic vestibular symptoms. However, it is underused in general practice. Internet-based vestibular rehabilitation (Vertigo Training), which has proven to be effective as well, was developed to increase uptake. We now aim to improve the quality of care for patients with vestibular symptoms by carrying out a nationwide implementation of Vertigo Training. We will evaluate the effect of this implementation on primary care.

METHODS

Our implementation study consists of three successive phases: 1) We will perform a retrospective observational cohort study and a qualitative interview study to evaluate the current management of patients with vestibular symptoms in primary care, in particular anti-vertigo drug prescriptions, and identify areas for improvement. We will use the results of this phase to tailor our implementation strategy to the needs of general practitioners (GPs) and patients. 2) This phase entails the implementation of Vertigo Training using a multicomponent implementation strategy, containing: guideline adaptations; marketing strategy; pharmacotherapeutic audit and feedback meetings; education; clinical decision support; and local champions. 3) In this phase, we will evaluate the effect of the implementation in three ways. a. Interrupted time series. We will use routine primary care data from adult patients with vestibular symptoms to compare the number of GP consultations for vestibular symptoms, referrals for vestibular rehabilitation, prescriptions for anti-vertigo drugs, and referrals to physiotherapy and secondary care before and after implementation. b. Prospective observational cohort study. We will extract data from Vertigo Training to investigate the usage and the characteristics of participants. We will also determine whether these characteristics are associated with successful treatment. c. Qualitative interview study. We will conduct interviews with GPs to explore their experiences with the implementation.

DISCUSSION

This is one of the first studies to evaluate the effect of a nationwide implementation of an innovative treatment on Dutch primary care. Implementation strategies have been researched before, but it remains unclear which ones are the most effective and under what conditions. We therefore expect to gain relevant insights for future projects that aim to implement innovations in primary care.

Using normalisation process theory for intervention development, implementation and refinement in musculoskeletal and orthopaedic interventions: a qualitative systematic review

BACKGROUND

Normalisation process theory (NPT) provides researchers with a set of tools to support the understanding of the implementation, normalisation and sustainment of an intervention in practice. Previous reviews of published research have explored NPT's use in the implementation processes of healthcare interventions. However, its utility in intervention research, specifically in orthopaedic and musculoskeletal interventions, remains unclear. The aim of this review is to explore how NPT (including extended NPT, ENPT) has been used in orthopaedic/musculoskeletal intervention research.

METHODS

A qualitative systematic review was conducted. Two bibliographic databases (Scopus and Web of Science) and a search engine (Google Scholar) were searched for peer-reviewed journal articles citing key papers outlining the development of NPT, related methods, tools or the web-based toolkit. We included studies of any method, including protocols, and did not exclude based on published language. A data extraction tool was developed, and data were analysed using a framework approach.

RESULTS

Citation searches, of the 12 key studies, revealed 10,420 citations. Following duplicate removal, title, abstract and full-text screening, 14 papers from 12 studies were included. There were 8 key findings assessed against GRADE-CERQual (Confidence in Evidence from Reviews of Qualitative research). Five were of high confidence supporting NPT/ENPT's use in the implementation process for interventions targeting a range of MSK/orthopaedic conditions. NPT/ENPT offers a useful analytical lens to focus attention and consider implementation factors robustly. There is limited evidence for the selection of NPT/ENPT and for the use of the Normalisation Measure Development instrument. Three findings of moderate confidence suggest that coherence is seen as a fundamental initial step in implementation, there is limited evidence that study population limits NPT's utility and the application of ENPT may pose a challenge to researchers.

CONCLUSION

This review demonstrates NPT's utility in supporting intervention implementation for orthopaedic and musculoskeletal conditions. We have theorised the benefits ENPT offers to intervention development and refinement and recommend future researchers consider its use. We also encourage future researchers to offer clear justification for NPT's use in their methodology.

What is the current status of primary care in the diagnosis and treatment of patients with vertigo and dizziness in Switzerland? A national survey

Background

Vertigo and dizziness are among the most frequent presenting symptoms in the primary care physicians' (PCPs) office. With patients facing difficulties in describing their complaints and clinical findings often being subtle and transient, the diagnostic workup of the dizzy patient remains challenging. We aimed to gain more insights into the current state of practice in order to identify the limitations and needs of the PCPs and define strategies to continuously improve their knowledge in the care of the dizzy patient.

Materials and methods

Board-certified PCPs working in Switzerland were invited to participate in an online survey. A descriptive statistical analysis was performed, and prospectively defined hypotheses were assessed using regression analyses.

Results

A vast majority of participating PCPs (n = 152) were familiar with the key questions when taking the dizzy patient's history and with performing provocation/repositioning maneuvers when posterior-canal benign paroxysmal positional vertigo (BPPV) was suspected (91%). In contrast, strong agreement that performing the alternating cover test (21%), looking for a spontaneous nystagmus with fixation removed (42%), and performing the head-impulse test (47%) were important was considerably lower, and only 19% of PCPs were familiar with lateral-canal BPPV treatment. No specific diagnosis could be reached in substantial fractions of patients with acute (35% [25; 50%], median [inter-quartile range]) and episodic/chronic (50% [40; 65.8%]) dizziness/vertigo. Referral to specialists was higher in patients with episodic/chronic dizziness than in acutely dizzy patients (50% [20.3; 75] vs. 30% [20; 50]), with younger PCPs (aged 30-40 years) demonstrating significantly increased odds of referral to specialists (odds ratio = 2.20 [1.01-4.81], p = 0.048).

Conclusion

The assessment of dizzy patients takes longer than that of average patients in most primary care practices. Many dizzy patients remain undiagnosed even after a thorough examination, highlighting the challenges faced by PCPs and potentially leading to frequent referrals to specialists. To address this, it is crucial to promote state-of-the-art neuro-otological examination and treatment techniques that are currently neglected by most PCPs, such as "HINTS" and lateral-canal BPPV treatment. This can help reduce referral rates allowing more targeted treatment and referrals.

Needs and supporting tools for primary care physicians to improve care of patients with vertigo and dizziness: a national survey

Background

The diagnostic workup and treatment decisions for vertigo or dizziness in primary care can be challenging due to the broad range of possible causes and limited time and expertise of physicians. This can lead to delays in treatment and unnecessary tests. We aimed to identify the unmet needs of primary care physicians (PCPs) and strategies to improve care for dizzy patients.

Materials and methods

An online survey was conducted among board-certified PCPs in Switzerland to explore needs in caring for dizzy patients and potential educational approaches.

Results

Based on responses from 152 participating PCPs, satisfaction and confidence were higher in diagnosing (82%) and treating (76%) acute dizziness compared to episodic/chronic cases (63 and 59%, respectively). Younger PCPs had lower diagnostic yield and confidence. Areas for improvement in specialist interactions included communication between physicians (23%/36%; always/often true), shorter waiting times for consultations (19%/40%), more detailed feedback (36%/35%), and consistent patient back referrals (31%/30%). PCPs expressed interest in hands-on courses, workshops, practical guidelines, web-based algorithms, and digital tools such as printed dizzy diaries and apps for follow-up.

Conclusion

Enhanced dialog between PCPs and specialists is crucial to address the most common unmet needs. Reducing waiting times for referrals and providing clear instructions to specialists for triage are essential. The findings from this survey will guide the development of tools to improve the diagnosis and treatment of dizzy patients. Younger PCPs, who face higher diagnostic uncertainty, should be prioritized for educational approaches such as hands-on courses, workshops, and practical recommendations.

Perspectives of healthcare professionals and older patients on shared decision-making for treatment escalation planning in the acute hospital setting: a systematic review and qualitative thematic synthesis

Background

Shared Decision-Making (SDM) between patients and clinicians is increasingly considered important. Treament Escalation Plans (TEP) are individualised documents outlining life-saving interventions to be considered in the event of clinical deterioration. SDM can inform subjective goals of care in TEP but it remains unclear how much it is considered beneficial by patients and clinicians. We aimed to synthesise the existing knowledge of clinician and older patient (generally aged ≥65 years) perspectives on patient involvement in TEP in the acute setting.

Methods

Systematic database search was performed in MEDLINE, EMBASE, PsycInfo and CINAHL databases as well as grey literature from database inception to June 8, 2023, using the Sample (older patients, clinicians, acute setting; studies relating to patients whose main diagnosis was cancer or single organ failure were excluded as these conditions may have specific TEP considerations), Phenomenon of Interest (Treatment Escalation Planning), Design (any including interview, observational, survey), Evaluation (Shared Decision-Making), Research type (qualitative, quantitative, mixed methods) tool. Primary data (published participant quotations, field notes, survey results) and descriptive author comments were extracted and qualitative thematic synthesis was performed to generate analytic themes. Quality assessment was made using the Critical Appraisal Skills Programme and Mixed Methods Appraisal Tools. The GRADE-CERQual (Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research) approach was used to assess overall confidence in each thematic finding according to methodology, coherence, adequacy and relevance of the contributing studies. The study protocol was registered on PROSPERO, CRD42022361593.

Findings

Following duplicate exclusion there were 1916 studies screened and ultimately 13 studies were included, all from European and North American settings. Clinician-orientated themes were: treatment escalation is a medical decision (high confidence); clinicians want the best for their patients amidst uncertainty (high confidence); involving patients and families in decisions is not always meaningful and can involve conflict (high confidence); treatment escalation planning exists within the clinical environment, organisation and society (moderate confidence). Patient-orientated themes were: patients' relationships with Treatment Escalation Planning are complex (low confidence); interactions with doctors are important but communication is not always easy (moderate confidence); patients are highly aware of their families when considering TEP (moderate confidence).

Interpretation

Based on current evidence, TEP decisions appear dominated by clinicians' perspectives, motivated by achieving the best for patients and challenged by complex decisions, communication and environmental factors; older patients' perspectives have seldom been explored, but their input on decisions may be modest. Presenting the context and challenge of SDM during professional education may allow reflection and a more nuanced approach. Future research should seek to understand what approach to TEP decision-making patients and clinicians consider to be optimum in the acute setting so that a mutually acceptable standard can be defined in policy.

Exposure to anticholinergic and sedative medication is associated with impaired functioning in older people with vertigo, dizziness and balance disorders-Results from the longitudinal multicenter study MobilE-TRA

Introduction: Anticholinergic and sedative medication is prescribed for various conditions in older patients. While the general association between anticholinergic and sedative medication and impaired functioning is well established, its specific role in older individuals with vertigo, dizziness, and balance disorders (VDB) is still incompletely understood. The objective of this study was to investigate, whether an exposure to anticholinergic and sedative medication is associated with lower generic and lower vertigo-specific functioning in older patients with VDB. Methods: Data originates from the longitudinal multicenter study MobilE-TRA with two follow-ups, conducted from 2017 to 2019 in two German federal states. Exposure to anticholinergic and sedative medication was quantified using the drug burden index (DBI). Generic functioning was assessed by the Health Assessment Questionnaire Disability Index, appraising the amount of difficulties in performing activities of daily living (ADL). Vertigo-specific functioning was measured using the Vestibular Activities and Participation (VAP) questionnaire, assessing patient-reported functioning regarding activities of daily living that are difficult to perform because of their propensity to provoke VDB (Scale 1) as well as immediate consequences of VDB on activities and participation related to mobility (Scale 2). Longitudinal linear mixed models were applied to assess the association of exposure to anticholinergic and sedative medication at baseline and the level of generic and vertigo-specific functioning status over time. Results: An overall of 19 (7 from Bavaria) primary care physicians (mean age = 54 years, 29% female) recruited 158 (59% from Bavaria) patients with VDB (median age = 78 years, 70% female). Anticholinergic and sedative medication at baseline was present in 56 (35%) patients. An exposure to anticholinergic and sedative medication at baseline was significantly associated with lower generic functioning [Beta = 0.40, 95%-CI (0.18; 0.61)] and lower vertigo-specific functioning [VAP Scale 1: Beta = 2.47, 95%-CI (0.92; 4.02)], and VAP Scale 2: Beta = 3.74, 95%-CI [2.23; 5.24]). Conclusion: Our results highlight the importance of a close monitoring of anticholinergic and sedative medication use in older patients with VDB. When feasible, anticholinergic and sedative medication should be replaced by equivalent alternative therapies in order to potentially reduce the burden of VDB.

Effectiveness of a training intervention to improve the management of vertigo in primary care: a multicentre cluster-randomised trial, VERTAP

Background

Benign paroxysmal positional vertigo (BPPV) is the most common type of vertigo. While BPPV is best treated with canalicular repositioning manoeuvres, they are not routinely performed in primary care (PC).

Methods

To evaluate the effectiveness of blended training (online and face-to-face) on the diagnosis and management of vertigo to improve adherence of family doctors to clinical practice guidelines, we designed a community multicentre cluster-randomised open-label trial with an intervention (IG) and a control (GC) group of 10 primary care teams (PCT) each. Outcome variables will be ICD-10 diagnostic codes (proportion of nonspecific diagnoses such as dizziness and vertigo versus specific diagnoses such as BPPV, vestibular neuritis, and Menière’s disease); number of referrals to ENT or neurology specialists; prescription of antivertigo agents; and duration of sick leave due to vertigo. The baseline comparability of the two study groups will be analysed to ensure homogeneity. A description of all baseline variables will be performed. Student’s t-test will be used to evaluate the differences between the groups. Logistic regression multivariate analysis will be performed to study the relationship between baseline variables of professionals and centres with outcome variables.

Discussion

With the improvement of the diagnosis and management of vertigo by family doctors after this training, we expect an increase in the proportion of specific diagnoses, a decrease in the prescription of antivertigo agents, a decrease in referrals to ENT or neurology specialists and a reduction in the duration of sick leave due to temporary disability. The blended training will be easily expanded within primary care services, since it is mainly delivered online, with a single face-to-face session to ensure that the manoeuvres have been adequately learned.

Referral trajectories in patients with vertigo, dizziness and balance disorders and their impact on health-related quality of life and functioning: results from the longitudinal multicenter study MobilE-TRA

Background

Due to reported barriers in the management of patients with vertigo, dizziness and balance problems (VDB), referral trajectories starting from primary care might be determined by other factors than medical necessity. The objective of this paper was to examine the impact of disease-related and other determinants on referral trajectories of older patients with VDB and to investigate, how these trajectories affect the patients’ functioning and health-related quality of life (HRQoL).

Methods

Data originate from the longitudinal multicenter study MobilE-TRA, conducted in two German federal states. Referrals to neurologists or ear-nose-throat (ENT) specialists were considered. Referral patterns were visualized using a state sequence analysis. Predictors of referral trajectories were examined using a multinomial logistic regression model. Linear mixed models were calculated to assess the impact of referral patterns on the patients’ HRQoL and functioning.

Results

We identified three patterns of referral trajectories: primary care physician (PCP) only, PCP and neurologist, and PCP and ENT. Chances of referral to a neurologist were higher for patients with a neurological comorbidity (OR = 3.22, 95%-CI [1.003; 10.327]) and lower for patients from Saxony (OR = 0.08, 95%-CI [0.013; 0.419]). Patients with a PCP and neurologist referral pattern had a lower HRQoL and lower functioning at baseline assessment. Patients with unspecific diagnoses also had lower functioning.

Conclusion

Referral trajectories were determined by present comorbidities and the regional healthcare characteristics. Referral trajectories affected patients’ HRQoL. Unspecific VDB diagnoses seem to increase the risk of ineffective management and consequently impaired functioning.

Specificity of early-career general practitioners' problem formulations in patients presenting with dizziness: a cross-sectional analysis

OBJECTIVES

Dizziness is a common and challenging clinical presentation in general practice. Failure to determine specific aetiologies can lead to significant morbidity and mortality. We aimed to establish frequency and associations of general practitioner (GP) trainees' (registrars') specific vertigo provisional diagnoses and their non-specific symptomatic problem formulations.

DESIGN

A cross-sectional analysis of Registrar Clinical Encounters in Training (ReCEnT) cohort study data between 2010 and 2018. ReCEnT is an ongoing, prospective cohort study of registrars in general practice training in Australia. Data collection occurs once every 6 months midtraining term (for three terms) and entails recording details of 60 consecutive clinical consultations on hardcopy case report forms. The outcome factor was whether dizziness-related or vertigo-related presentations resulted in a specific vertigo provisional diagnosis versus a non-specific symptomatic problem formulation. Associations with patient, practice, registrar and consultation independent variables were assessed by univariate and multivariable logistic regression.

SETTING

Australian general practice training programme. The training is regionalised and delivered by regional training providers (RTPs) (2010-2015) and regional training organisations (RTOs) (2016-2018) across Australia (from five states and one territory).

PARTICIPANTS

All general practice registrars enrolled with participating RTPs or RTOs undertaking GP training terms.

RESULTS

2333 registrars (96% response rate) recorded 1734 new problems related to dizziness or vertigo. Of these, 546 (31.5%) involved a specific vertigo diagnosis and 1188 (68.5%) a non-specific symptom diagnosis. Variables associated with a non-specific symptom diagnosis on multivariable analysis were lower socioeconomic status of the practice location (OR 0.94 for each decile of disadvantage, 95% CIs 0.90 to 0.98) and longer consultation duration (OR 1.02, 95% CIs 1.00 to 1.04). A specific vertigo diagnosis was associated with performing a procedure (OR 0.52, 95% CIs 0.27 to 1.00), with some evidence for seeking information from a supervisor being associated with a non-specific symptom diagnosis (OR 1.39, 95% CIs 0.92 to 2.09; p=0.12).

CONCLUSIONS

Australian GP registrars see dizzy patients as frequently as established GPs. The frequency and associations of a non-specific diagnosis are consistent with the acknowledged difficulty of making diagnoses in vertigo/dizziness presentations. Continuing emphasis on this area in GP training and encouragement of supervisor involvement in registrars' diagnostic processes is indicated.

Multiple things going on at the same time: determinants of appropriate primary diabetic eyecare delivery

PURPOSE

A recent nationwide medical record audit of optometry practices has identified an evidence-to-practice gap in primary diabetic eyecare delivery. This study aimed to explore the determinants (barriers and enablers) to appropriate diabetic eyecare delivery in Australia.

METHODS

A qualitative study involving focus-group discussions and interviews of a purposeful sample of Australian optometrists was conducted. Participants were asked about the perceived barriers to adherence to four underperforming clinical indicators related to primary diabetic eyecare identified by the recent national optometry practice audit. The Theoretical Domain Framework was used for thematic analysis and coding salience to identify key behavioural determinants.

RESULTS

Optometrists participated in eight focus groups (n = 27) and individual interviews (n = 4). The most salient barriers were related to Environmental resources (e.g., limited chair time); Beliefs about consequences (e.g., lack of perceived importance); Knowledge (e.g., poor understanding); Professional role/identity (e.g., the perceived role of optometry in care process); Social influences (e.g., the influence of senior optometrists) and Intentions (e.g., apathy). Key enablers were Environmental resources (e.g., electronic record system and practice aids); Knowledge (e.g., keeping up with knowledge/professional development); reinforcements (e.g., fear of legal actions) and behavioural regulations (e.g., self-monitoring/audit).

CONCLUSIONS

This study shows that the evidence-to-practice gap in primary diabetic eyecare delivery in Australia can be attributed in part to several interconnected factors related to optometrists' individual capability and motivation as well as the social and practice environment within which they sit. These behavioural determinants will inform the design of an intervention to improve the appropriateness of primary diabetic eyecare delivery.

Computerized clinical decision system and mobile application with expert support to optimize management of vertigo in primary care: study protocol for a pragmatic cluster-randomized controlled trial

Vertigo and dizziness are amongst the most common symptoms in medicine and often have a major impact on activities of daily life. Although many causes of vertigo and dizziness can easily be recognized, patients often receive inappropriate and ineffective treatment. The reasons for this are various. Because vertigo/dizziness is an interdisciplinary symptom and there is a lack of standardised diagnostic tools, it is easy to lose the overview of the possible differential diagnoses. There is evidence though, that the management of patients with vertigo/dizziness can be optimized using standardized care pathways with digital support. The present study (within the framework of “PoiSe—prevention, online feedback, and interdisciplinary therapy of acute vestibular syndromes by e-health”) aims to evaluate the implementation of a program with several interlocking components. The three main components are a computerized clinical decision system, a mobile application, a counselling and interdisciplinary educational program developed by the German Center for Vertigo and Balance Disorders (DSGZ). The study is a cluster-randomized controlled trial with a parallel-group design, as well as a detailed process evaluation. Clusters comprise of primary care physician practices in Bavaria, Germany. In the scope of the study the effectiveness, acceptability and efficiency of the intervention will be evaluated. It is anticipated that the intervention will improve the quality and efficiency of the management of dizzy patients. A higher diagnostic accuracy, optimized treatment, and disease progression monitoring is expected to improve patient-relevant outcomes and reduce health-care costs.

Economic burden of vertigo: a systematic review

BACKGROUND

Vertigo, a highly prevalent disease, imposes a rising burden on the health care system, exacerbated by the ageing of the population; and further, contributes to a wide span of indirect burden due to reduced capacity to work or need of assistance in activities of daily living. The aim of this review was to summarise the evidence on the economic burden of vertigo.

METHODS

All original studies published between 2008 and 2018 about the economic evaluation of peripheral or central vestibular vertigo in developed countries were considered eligible, unrestricted to setting, health care provider, or study type.

RESULTS

The electronic search in three databases identified 154 studies from which 16 qualified for inclusion. All studies presented partial economic evaluation referring to a variety of vestibular vertigo including unspecified vertigo. Nine studies presented monetised cost results and seven studies reported health care utilization. Direct costs derived mainly from repeated and not well-targeted consultations at all levels of health care, excessive use of diagnostic imaging, and/or of emergency care. Considerable societal burden was caused by decreased productivity, mainly due to work absenteeism.

CONCLUSION

To the best of our knowledge, this is the first systematic review of the existing evidence of the economic burden of vertigo. The lack of conclusive evidence revealed apparent targets of future research. First, studies of diagnostics and therapies for vestibular disease should include cost-effectiveness considerations. Population-based studies of health services utilization should include simple vestibular assessments to get more reliable estimates of the burden of disease and associated costs on the level of the general population. Further, clinical and population-based registries that include patients with vestibular disease, should consider collecting long-term data of societal burden. Primary data collection should increasingly include assessment of health care utilization e.g. by linking their diagnoses and outcomes to routine data from health insurances.

Who is responsible for assessing children's weight status? - a qualitative study of health professionals in regional Australia

Background

Currently in Australia there is a lack of clarity regarding routine assessment of primary school aged children’s weight status despite it being the first step in the identification of overweight and obesity. The National Health and Medical Research Council Obesity Guidelines recommend primary health care professionals include routine weight status assessment in consultations with children yet research suggests this rarely occurs in practice.

This study aimed to determine the views of primary health care professionals regarding routine weight status assessment in primary school aged children and to establish the barriers to assessing children’s weight status.

Methods

Using the case study of a regional town, Rockhampton, purposeful sampling was used to represent the key primary health care settings and professional groups. Interviews were conducted with 31 health professionals. Data were collected and analysed guided by two frameworks, the Capability, Opportunity, Motivation and Behaviour and Theoretical Domains Frameworks.

Results

Eight themes emerged from data and these were relevant to the three levels of influence on the routine weight status of assessment, system, setting and individual. System level themes related to having a formalised program for the undertaking of routine weight status assessment in primary school aged children, increasing the population’s awareness about the importance of the weight status check and limited public health services available for management of childhood overweight and obesity. Setting level theme regarded the location where routine weight status in primary school aged children could be undertaken. Four themes at the individual level of influence on the routine weight status assessment related to the primary health professionals’ roles, barriers to assessing children’s weight status, methods of weight status assessment and starting a weight related conversations with families.

Conclusion

The Government, primary health care services, professional organisations and associations as well as health professionals must commit to long-term implementation of the Obesity Guidelines. Immediate action to improve the undertaking of routine weight status assessment in children must be taken by each health service and health professional. Strategies should aim to positively affect motivation to assess children’s weight status as it is the central component in creating change in practice.

Feasibility of referral to a therapist for assessment of psychiatric problems in primary care - an interview study

Background

Depression and anxiety disorders are common in primary care. Comorbidities are frequent, and the diagnoses can be difficult. The Mini-International Neuropsychiatric Interview (MINI) can be a support in the clinical examination of patients with complex problems. However, for family practitioners (FPs), time and perceptions about structured interviews can be barriers to the MINI. An inter-professional teamwork process where FPs refer a patient to a therapist for a MINI assessment represents one way in which to address the problem. The results are fed back to the FPs for diagnosis and treatment decisions.

The purposes of this study were to explore if the process was feasible for FPs, patients and therapists in Swedish primary care, and to identify factors influencing the process, using the COM-B model.

Methods

FPs at two primary care centers (PHCC) in Stockholm were offered the opportunity to refer patients to in-house therapists. Semi-structured interviews or focus groups were conducted with 22 patients, 17 FPs and three therapists to capture their experiences and perceptions. Inductive content analysis for each group of participants was followed by triangulation across groups. Finally, the categories obtained were fitted to the components in the COM-B.

Results

Therapists at both PHCCs conducted the MINI. The intended process was adopted at one PHCC. At the second PHCC, the responsibilities for the diagnosis and treatment of patients referred were transferred to the therapist. The patients were satisfied, as they appreciated multi-professional examinations. The FPs’ competence in psychiatry, actual access to therapists, beliefs that the referrals saved the FPs time and effort, and established habits influenced whether patients were referred. Existing routines and professional expectations for work content influenced the degree of cooperation between the therapists and the FPs.

Conclusions

An inter-professional diagnostic process where FPs refer patients to a therapist for assessment and the results are fed back to the FPs can be feasible. Feasibility depends on access to a therapist, the perceptions of roles and competences among FPs and therapists, and strategies for supporting teamwork.

Diagnosis and treatment choices of suspected benign paroxysmal positional vertigo: current approach of general practitioners, neurologists, and ENT physicians

PURPOSE

Benign paroxysmal positional vertigo (BPPV) is a frequently underdiagnosed cause of vertigo, potentially due to the underuse of diagnostic and therapeutic canalith repositioning procedures (CRPs). We aimed to investigate self-reported use of the diagnostic and therapeutic approach to BPPV patients by Lithuanian neurologists, ear, nose, and throat (ENT) physicians, and general practitioners (GPs), and to explore potential reasons for the underuse of the maneuvers.

METHODS

Neurologists, ENT physicians, and GPs were invited to complete a written questionnaire focused on diagnostic and therapeutic practices related to BPPV. Between-group differences and associations between responses were analyzed statistically.

RESULTS

In total, 97 neurologists, 85 ENT physicians and 142 GPs (21.1%, 26.8%, and 5.7%, respectively, of all corresponding licensed Lithuanian physicians) completed the questionnaire. 24% of neurologists, 33% ENT physicians and 50% GPs do not perform diagnostic maneuvers for patients with suspected BPPV, and 28%, 61%, and 84%, respectively, do not perform CRPs. Years of clinical experience was a negative predictor of CRP performance [OR 0.97 (95% CI 0.95-0.99), p = 0.001]. Frequent reasons for not performing CRPs were time taken for the procedure, fear of provoking symptoms, and lack of knowledge. All physicians frequently ordered additional imaging or consultations for suspected BPPV and reported prescribing a range of medications.

CONCLUSIONS

A significant proportion of Lithuanian neurologists, ENT physicians, and GPs do not employ diagnostic maneuvers and CRPs for BPPV patients, contrary to established guidelines. Lack of expertise and time available is a common culprit that leads to unnecessary drug prescribing and investigation.

Patient trajectories and their impact on mobility, social participation and quality of life in patients with vertigo/dizziness/balance disorders and osteoarthritis (MobilE-TRA): study protocol of an observational, practice-based cohort study

INTRODUCTION

Mobility limitations have a multitude of different negative consequences on elderly patients including decreasing opportunities for social participation, increasing the risk for morbidity and mortality. However, current healthcare has several shortcomings regarding mobility sustainment of older adults, namely a narrow focus on the underlying pathology, fragmentation of care across services and health professions and deficiencies in personalising care based on patients' needs and experiences. A tailored healthcare strategy targeted at mobility of older adults is still missing.

OBJECTIVE

The objective is to develop multiprofessional care pathways targeted at mobility sustainment and social participation in patients with vertigo/dizziness/balance disorders (VDB) and osteoarthritis (OA) .

METHODS

Data regarding quality of life, mobility limitation, pain, stiffness and physical function is collected in a longitudinal observational study between 2017 and 2019. General practitioners (GPs) recruit their patients with VDB or OA. Patients who visited their GP in the last quarter will be identified in the practice software based on VDB and OA-related International Classification of Diseases 10th Revision. Study material will be sent from the practice to patients by mail. Six months and 12 months after baseline, all patients will receive a mail directly from the study team containing the follow-up questionnaire. GPs fill out questionnaires regarding patient diagnostics, therapy and referrals.

ETHICS AND DISSEMINATION

The study was approved by the ethical committee of the Ludwig-Maximilians-Universität München and of the Technische Universität Dresden. Results will be published in scientific, peer-reviewed journals and at national and international conferences. Results will be disseminated via newsletters, the project website and a regional conference for representatives of local and national authorities.
