Overdiagnosis and overtreatment as a quality problem: insights from healthcare improvement research

Evaluation of the Diagnosis and Antibiotic Prescription Pattern in Patients Hospitalized with Urinary Tract Infections: Single-Center Study from a University-Affiliated Hospital

UTIs (urinary tract infections) are common bacterial infections with a non-negligible hospitalization rate. The diagnosis of UTIs remains a challenge for prescribers and a common source of misdiagnosis. This retrospective observational study aimed to evaluate whether recorded diagnosis by clinicians and empirical antibiotic therapy met the EAU (European Association of Urology) guideline in patients hospitalized with UTI. The study was conducted at an internal medicine unit of a tertiary care medical center in Hungary. The diagnosis was assessed based on clinical presentation, physical examination, and laboratory (including microbiological) results, considering all the potential risk factors. Diagnosis was considered misdiagnosis when not confirmed by clinical presentation or clinical signs and symptoms. Evaluation of empirical antibiotic therapy was performed only for confirmed UTIs. Empirical treatment was considered guideline-adherent when complying with the relevant recommendations. Out of 185 patients, 41.6% failed to meet EAU-based UTI diagnosis criteria, of which 27.6% were misdiagnosed and 14.1% were ABU (asymptomatic bacteriuria). The diagnosis of urosepsis recorded at admission (9.7%, 18/185) was not confirmed either by clinical or microbiological tests in five (5/18) cases. The initial empirical therapies for UTI showed a relatively low rate (45.4%) of guideline adherence regarding agent selection. The most common guideline-non-adherent therapies were combinations with metronidazole (16.7%). Dosage appropriateness assessments showed a guideline adherence rate of 36.1%, and underdosing due to high body weight was common (9.3%). Overall (agent, route of administration, dose, duration) guideline adherence was found to be substantially low (10.2%). We found a relatively high rate of misdiagnosed UTIs. Written protocols on the ward may be crucial in reducing misdiagnosis and in optimizing antibiotic use.

Chronic Obstructive Pulmonary Disease Overdiagnosis and Overtreatment: A Meta-Analysis

This meta-analysis of observational studies aimed at estimating the overall prevalence of overdiagnosis and overtreatment in subjects with a clinical diagnosis of Chronic Obstructive Pulmonary Disease (COPD). MedLine, Scopus, Embase and Cochrane databases were searched, and random-effect meta-analyses of proportions were stratified by spirometry criteria (Global Initiative for COPD (GOLD) or Lower Limit of Normal (LLN)), and setting (hospital or primary care). Forty-two studies were included. Combining the data from 39 datasets, including a total of 23,765 subjects, the pooled prevalence of COPD overdiagnosis, according to the GOLD definition, was 42.0% (95% Confidence Interval (CI): 37.3-46.8%). The pooled prevalence according to the LLN definition was 48.2% (40.6-55.9%). The overdiagnosis rate was higher in primary care than in hospital settings. Fourteen studies, including a total of 8183 individuals, were included in the meta-analysis estimating the prevalence of COPD overtreatment. The pooled rates of overtreatment according to GOLD and LLN definitions were 57.1% (40.9-72.6%) and 36.3% (17.8-57.2%), respectively. When spirometry is not used, a large proportion of patients are erroneously diagnosed with COPD. Approximately half of them are also incorrectly treated, with potential adverse effects and a massive inefficiency of resources allocation. Strategies to increase the compliance to current guidelines on COPD diagnosis are urgently needed.

Evidencing general acceptability of open-label placebo use for tackling overtreatment in primary care: a mixed methods study

BACKGROUND

Overtreatment poses a challenge to healthcare systems due to harmful consequences of avoidable side-effects and costs. This study presents the first account for examining the feasibility of placebo use for reducing overtreatment in primary care, including whether public attitudes support the use of different placebo types in place of inappropriate prescriptions of antibiotics, antidepressants, or analgesics.

METHODS

We used a multi-study, mixed-methods design, including patient and public (PPI) consultations, focus groups (Study 1) and two pre-registered online experiments (Studies 2 and 3).

RESULTS

Study 1 (N = 16) explored everyday conceptions and practicalities of potential placebo use in the context of respiratory infections. Findings highlighted the importance of trusting doctor-patient relationships and safety-netting. Study 2 employed a randomised experiment with a representative UK sample (N = 980), investigating attitudes towards 5 different treatment options for respiratory infections: (1) blinded + pure placebo, (2) open-label + pure placebo, (3) open-label + impure placebo, (4) antibiotic treatment, and (5) no treatment. Study 2 also examined how attitudes varied based on wording and individual differences. Findings indicated general support (ηp2 = .149, large effect size) for replacing inappropriate antibiotics with open-label + impure placebos, although personal placebo acceptability was lower. Also, older people, individuals suffering from chronic illness or those showing higher levels of health anxiety appeared less amenable to placebo use. Study 3 (N = 1177) compared attitudes towards treatment options across three clinical scenarios: respiratory infection, depression and pain. Findings suggested significant differences in the acceptability of placebo options based on the clinical context. In the infection scenario, options for open-label + pure placebos, open-label + impure placebos and no treatment were rated significantly more acceptable (ηp2 = .116, medium effect size) compared to the depression and pain scenarios. Again, general support for placebos was higher than placebo acceptability for personal use.

CONCLUSIONS

Findings from PPI and three studies indicate general support for combatting overprescribing in primary care through clinical placebo use. This is an indicator for wider UK public support for a novel, behavioural strategy to target a long-standing healthcare challenge. General acceptability appears to be highest for the use of open-label + impure placebos in the context of antibiotic overprescribing.

A qualitative study on the experiences of southern European immigrant parents navigating the Norwegian healthcare system

BACKGROUND

Patients' experiences with health providers and their diagnostic and treatment expectations are shaped by cultural health beliefs and previous experiences with healthcare services in home country. This study explores how Southern European immigrant parents navigate the Norwegian healthcare system, through its focus on how this group manage their expectations on diagnosis and treatment practices when these are unmet.

METHODS

The study had a qualitative research design. Fourteen in-depth interviews and two focus group discussions with 20 Southern European immigrant parents were conducted in 2017 in three Norwegian municipalities. With the help of NVivo software, data were transcribed verbatim and coded. Following a thematic analysis approach to identify patterns in immigrants' experiences with the Norwegian healthcare services, the codes were organized into two themes.

RESULTS

The first theme includes immigrants' expectations on diagnostic tests and medical treatment. Southern European immigrants expected more diagnostic tests and pharmacological treatment than what was deemed necessary by Norwegian health providers. Experiences with unmet expectations influenced how immigrants addressed their and their children's healthcare needs. The second theme comprises immigrants' experiences of seeking healthcare in Norway (attending medical consultations in the private sector, seeking immigrant healthcare providers, and navigating the healthcare through their Norwegian social networks). This category includes also the alternative solutions immigrants undertook when they were dissatisfied with the diagnosis and treatment practices they were offered in Norway (self-medication and seeking healthcare in home countries).

CONCLUSIONS

Cultural health beliefs and previous experiences with healthcare services from home country shaped immigrants' expectations on diagnosis and treatment practices. This had great implications for their navigation through the healthcare system and interactions with health providers in the host country. The study suggests that successful inclusion of immigrants into the Norwegian healthcare system requires an acknowledgement of the cultural factors that influence access and use of healthcare services. Exploring immigrants' perspectives and experiences offers important information to understand the challenges of cross-cultural healthcare and to improve communication and equitable access.

Treatment for acute bronchiolitis before and after implementation of new national guidelines: a retrospective observational study from primary and secondary care in Oslo, Norway

BACKGROUND

Acute bronchiolitis treatment guidelines changed in Norway in 2013, no longer recommending the use of nebulised epinephrine. We aimed to assess whether these changes were successfully implemented in both primary and secondary care. Secondary aims were to compare the difference in management of acute bronchiolitis patients in primary and secondary care between 2009 and 2017.

METHODS

We retrospectively registered data on demographics, clinical features and management from electronic medical records of all infants (<12 months of age) diagnosed with acute bronchiolitis at a primary care centre (Oslo Accident and Emergency Outpatient Clinic) and a secondary care centre (Oslo University Hospital) in Norway in 2009, 2014 and 2017. All patient records were individually reviewed to ensure data accuracy.

RESULTS

We included 680 (36.3%) patients from primary care and 1195 (63.7%) from secondary care. There was a reduction in the use of nebulised epinephrine from 2009 to 2017 from 66.9% to 16.1% of cases (p<0.001) in primary care and from 59.1% to 4.9% (p<0.001) in secondary care. In parallel, there was an increase in the use of nebulised saline treatment, from 0.8% to 53.8% (p<0.001) in primary care and from 39.3% to 65.3% (p<0.001) in secondary care. The decrease in the use of nebulised racemic epinephrine occurred earlier in secondary care than in primary care; 13.4% vs 56.1%, respectively, in 2014.

CONCLUSIONS

Implementation of the new guidelines on the treatment of acute bronchiolitis was successfully implemented in both primary and secondary care.

The Management Script: A Practical Tool for Teaching Management Reasoning

Management reasoning, a component of clinical reasoning, has become an important area for medical education research given its inherent complexity, role in medical decision making, and association with high-value care. Teaching management reasoning requires characterizing its core concepts and identifying strategies to teach them. In this Perspective, the authors propose the term "management script" to describe the mental schema that clinicians develop and use in medical decision making. Management scripts are high-level, precompiled, conceptual knowledge structures of the courses of action that a clinician may undertake to address a patient's health care problem(s). Like illness scripts, management scripts have foundational elements that are shared by most clinicians but are ultimately idiosyncratic based on each clinician's unique history of learning and experience. Applying management scripts includes 2 steps-(1) management script activation and (2) management option selection-which can occur reflexively (unconsciously) or deliberately (consciously), similar to, respectively, the System 1 thinking and System 2 thinking of dual process theory. Management scripts can be taught for different conditions by using management script templates, educational scaffolds that provide possible courses of action to address a health care problem at any stage. Just as learners use system-based or organ-based frameworks to generate a differential diagnosis, students can use a generic management script template early in training to develop management scripts for specific problems. Future research directions include exploring the role of management scripts in medical education and quality improvement practices.

Understanding and managing uncertainty in health care: revisiting and advancing sociological contributions

In this collection we revisit the enduring phenomenon of uncertainty in health care, and demonstrate how it still offers coherence and significance as an analytic concept. Through empirical studies of contemporary examples of health care related uncertainties and their management, our collection explores the different ways in which uncertainty may be articulated, enacted and experienced. The papers address a diverse range of healthcare contexts - Alzheimer's disease, neonatal surgery, cardiovascular disease prevention, cancer, addiction (use of alcohol and other drugs during pregnancy), mental health/disorders and medical education - and many tackle issues of contemporary relevance, such as an ageing population, and novel medical interventions and their sequelae. These empirical papers are complemented by a further theoretical contribution, which considers the role of 'implicit normativity' in masking and containing potential ethical uncertainty. By mapping themes across the collection, in this introduction we present a number of core analytical strands: (1) conceptualising uncertainty; (2) intersections of uncertainty with aspects of care; (3) managing uncertainty; and (4) structural constraints, economic austerity and uncertainty work. We reflect on the methodological and theoretical stances used to think sociologically about uncertainty in health care, and the strengths, silences and gaps we observe in the collection. We conclude by considering the implications of the insights gained for 'synthesising certainty' in practice and for future research in this area.

A Model for Cultivating a Culture of Continuous Learning and Improvement: An Ethnographic Report

The importance of culture is often emphasized for continuous learning and quality improvement within health care organizations. Limited empirical evidence for cultivating a culture that supports continuous learning and quality improvement in health care settings is currently available. The purpose of this report is to characterize the evolution of a large division of physical therapists and occupational therapists in a pediatric hospital setting from 2005 to 2018 to identify key facilitators and barriers for cultivating a culture empowered to engage in continuous learning and improvement. An ethnographic methodology was used including participant observation, document review, and stakeholder interviews to acquire a deep understanding and develop a theoretical model to depict insights gained from the investigation. A variety of individual, social, and structural enablers and motivators emerged as key influences toward a culture empowered to support continuous learning and improvement. Features of the system that helped create sustainable, positive momentum (e.g., systems thinking, leaders with grit, and mindful design) and factors that hindered momentum (e.g., system uncertainty, staff turnover, slow barrier resolution, and competing priorities) were also identified. Individual-level, social-level, and structural-level elements all influenced the culture that emerged over a 12-year period. Several cultural catalysts and deterrents emerged as factors that supported and hindered progress and sustainability of the emergent culture. Cultivating a culture of continuous learning and improvement is possible. Purposeful consideration of the proposed model and identified factors from this report may yield important insights to advance understanding of how to cultivate a culture that facilitates continuous learning and improvement within a health care setting.

Overprescribing antibiotics for asymptomatic bacteriuria in older adults: a case series review of admissions in two UK hospitals

Background

Overdiagnosis and overtreatment of urinary tract infection (UTI) with antibiotics is a concern. In older adults, diagnosis of UTI using near-patient urine tests (reagent strip tests, dipsticks) is advised against because the age-related increase in asymptomatic bacteriuria can cause false-positive results. Instead, UTI diagnosis should be based on a full clinical assessment. Previous research lacks systematic information on urine dipstick use in hospitals. The aim of this study was to examine the use of urine dipstick tests and microbiology among older adult hospital admissions in relation to recommended UTI diagnostic criteria. A further aim was to assess factors associated with the use of dipsticks.

Methods

A case series review of patients aged ≥70 years admitted to two NHS Trust hospitals in England. Records from 312 patients admitted in 2015 meeting inclusion criteria were selected at random.

Results

Of 298 complete patient records, 54% had at least one urine dipstick test recorded. 13% (21/161) of patients who received a urine dipstick test were diagnosed as having a UTI, only 2 out of these 21 cases had two or more clinical signs and symptoms. 60 patients received a second dipstick test, leading to 13 additional cases of UTI diagnosis. Dipstick tests were more likely to be performed on patients with a history of falls (OR 1.93, 95% CI:1.21, 3.07, p < 0.01), and less likely on those with dementia (OR 0.44, 95% CI: 0.22, 0.87, p < 0.05). The most common reason for testing was routine admissions policy (49.1% of cases), but these cases were predominantly in one hospital.

Conclusions

Use of urine dipstick tests was high among older adults admitted to hospitals. Most cases were asymptomatic and therefore received inappropriate antibiotic therapy. This paper highlights the need to implement new Public Health England diagnostic guidelines to hospital admission and emergency departments.

Grade-specific diagnostic and prognostic biomarkers in breast cancer

An integrative approach is presented to identify grade-specific biomarkers for breast cancer. Grade-specific molecular interaction networks were constructed with differentially expressed genes (DEGs) of cancer grade 1, 2, and 3. We observed that the molecular network of grade3 is predominantly associated with cancer-specific processes. Among the top ten connected DEGs in the grade3, the increase in the expression of UBE2C and CCNB2 genes was statistically significant across different grades. Along with UBE2C and CCNB2 genes, the CDK1, KIF2C, NDC80, and CCNB2 genes are also profoundly expressed in different grades and reduce the patient's survival. Gene set enrichment analysis of these six genes reconfirms their role in metastatic phenotype. Moreover, the coexpression network shows a strong association of these six genes promotes cancer specific biological processes and possibly drives cancer from lower to a higher grade. Collectively the identified genes can act as potential biomarkers for breast cancer diagnosis and prognosis.
