Patient-related factors associated with an increased risk of being a reported case of preventable harm in first-line health care: a case-control study

Influence of comorbid depression and diagnostic workup on diagnosis of physical illness: a randomized experiment

OBJECTIVES

Patients with mental illness are less likely to receive the same physical healthcare as those without mental illness and are less likely to be treated in accordance with established guidelines. This study employed a randomized experiment to investigate the influence of comorbid depression on diagnostic accuracy.

METHODS

Physicians were presented with an interactive vignette describing a patient with a complex presentation of pernicious anemia. They were randomized to diagnose either a patient with or without (control) comorbid depression and related behaviors. All other clinical information was identical. Physicians recorded a differential diagnosis, ordered tests, and rated patient likeability.

RESULTS

Fifty-nine physicians completed the study. The patient with comorbid depression was less likeable than the control patient (p=0.03, 95 % CI [0.09, 1.53]). Diagnostic accuracy was lower in the depression compared to control condition (59.4 % vs. 40.7 %), however this difference was not statistically significant χ2(1)=2.035, p=0.15. Exploratory analyses revealed that patient condition (depression vs. control) interacted with the number of diagnostic tests ordered to predict diagnostic accuracy (OR=2.401, p=0.038). Accuracy was lower in the depression condition (vs. control) when physicians ordered fewer tests (1 SD below mean; OR=0.103, p=0.028), but there was no difference for physicians who ordered more tests (1 SD above mean; OR=2.042, p=0.396).

CONCLUSIONS

Comorbid depression and related behaviors lowered diagnostic accuracy when physicians ordered fewer tests - a time when more possibilities should have been considered. These findings underscore the critical need to develop interventions to reduce diagnostic error when treating vulnerable populations such as those with depression.

Mental health bias in physical care: An integrative review of the literature

WHAT IS KNOWN ON THE SUBJECT?: Individuals experiencing mental illness make up a significant portion of the world's population. Individuals with mental illness experience higher rates of morbidity and die on average at least a decade earlier than individuals without mental health disorders. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Issues of stigma, diagnostic overshadowing, premature closure, inadequate workup, fear and lack of training negatively impact the care of individuals with mental illness. Issues impacting the care of individuals experiencing mental illness cross geographic and care setting boundaries. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Partnerships between physical and mental health practitioners are needed to thoroughly assess and accurately diagnose symptoms experienced by individuals with mental illness. Educational interventions can help prepare practitioners to care for individuals with mental illness. Nurses can better advocate for effective patient care by learning about the phenomenon of diagnostic overshadowing and calling attention to its occurrence. ABSTRACT: Introduction Individuals with mental illness experience significantly higher overall rates of morbidity and mortality than counterparts without mental illness. Misdiagnosis of symptoms emanating from physical illnesses as psychiatric in nature presents one important cause. Aim This integrative review explores research on healthcare professionals' misattribution of physical health symptoms to patients' comorbid psychiatric issues and seeks to identify unifying themes, shared causes, and possible strategies for addressing the issue. Method This review uses Whittemore and Knafl's 2005 integrative review methodology coupled with vetted quality appraisal tools. Results Following a systematic search of allied health, medical, psychological, sociological and general literature, 24 publications employing qualitative, quantitative, mixed and synthesis research methodologies were selected. Each study was appraised according to design, and relevant data were extracted. Discussion Themes of stigmatization, diagnostic overshadowing, incomplete medical examination, insufficient training, and fears experienced by providers and patients emerged. Implications for Practice Increased partnering between physical and mental health practitioners, continuing education, and improving patient-provider communication are key to providing equitable care. Nurses play primary roles in empathizing with patients, advocating for appropriate care and educating others on the dangers of misattributing physical symptoms to psychiatric cause.

Stigma and functional neurological disorder: a research agenda targeting the clinical encounter

Stigma against patients with functional neurological disorder (FND) presents obstacles to diagnosis, treatment, and research. The lack of biomarkers and the potential for symptoms to be misunderstood, invalidated, or dismissed can leave patients, families, and healthcare professionals at a loss. Stigma exacerbates suffering and unmet needs of patients and families, and can result in poor clinical management and prolonged, repetitive use of healthcare resources. Our current understanding of stigma in FND comes from surveys documenting frustration experienced by providers and distressing healthcare interactions experienced by patients. However, little is known about the origins of FND stigma, its prevalence across different healthcare contexts, its impact on patient health outcomes, and optimal methods for reduction. In this paper, we set forth a research agenda directed at better understanding the prevalence and context of stigma, clarifying its impact on patients and providers, and promoting best practices for stigma reduction.

Multimorbidity and patient-reported diagnostic errors in the primary care setting: multicentre cross-sectional study in Japan

OBJECTIVES

There is lack of evidence for the association between multimorbidity and diagnostic errors. Information on diagnostic errors from patients' perspectives is crucial to improve the diagnostic process. In this study, we aimed to investigate patient-reported diagnostic errors and to examine the relationship between multimorbidity and patient-reported diagnostic errors in the primary care setting.

DESIGN

Multicentre cross-sectional study.

SETTING

A primary care practice-based research network in Japan (25 primary care facilities).

PARTICIPANTS

Adult outpatients filled out a standardised questionnaire.

PRIMARY OUTCOME MEASURE

Patient-reported diagnostic errors.

RESULTS

Data collected from 1474 primary care outpatients were analysed. The number of participants who reported diagnostic errors was 57 (3.9%). Most of the missed diagnoses were common conditions in primary care, such as cancer, dermatitis and hypertension. After adjustment for possible confounders and clustering within facilities, multimorbidity was positively associated with patient-reported diagnostic errors (adjusted OR=1.83, 95% CI 1.01 to 3.31). The results of the sensitivity analysis were consistent with those of the primary analysis.

CONCLUSIONS

The present study showed a lower proportion of patients reporting experiences of diagnostic errors in primary care than those reported in previous studies in other countries. However, patients with multimorbidity are more likely to report diagnostic errors in primary care; thus, further research is necessary to improve the diagnostic process for patients with multimorbidity.
