Diagnostic error in the pediatric hospital: a narrative review

INTRODUCTION

Diagnostic error is a prevalent type of medical error that is associated with considerable patient harm and increased medical costs. The majority of literature guiding the current understanding of diagnostic error in the hospital setting is from adult studies. However, there is research to suggest this type of error is also prevalent in the pediatric specialty.

OBJECTIVES

The primary objective of this study was to define the current understanding of diagnostic error in the pediatric hospital through a structured literature review.

METHODS

We searched PubMed and identified studies focusing on three aspects of diagnostic error in pediatric hospitals: the incidence or prevalence, contributing factors, and related interventions. We used a tiered review, and a standardized electronic form to extract data from included articles.

RESULTS

Fifty-nine abstracts were screened and 23 full-text studies were included in the final review. Seventeen of the 23 studies focused on the incidence or prevalence, with only 3 studies investigating the utility of interventions. Most studies took place in an intensive care unit or emergency department with very few studies including only patients on the general wards. Overall, the prevalence of diagnostic error in pediatric hospitals varied greatly and depended on the measurement technique and specific hospital setting. Both healthcare system factors and individual cognitive factors were found to contribute to diagnostic error, with there being limited evidence to guide how best to mitigate the influence of these factors on the diagnostic process.

CONCLUSION

The general knowledge of diagnostic error in pediatric hospital settings is limited. Future work should incorporate structured frameworks to measure diagnostic errors and examine clinicians' diagnostic processes in real-time to help guide effective hospital-wide interventions.

Pediatric Clinician Comfort Discussing Diagnostic Errors for Improving Patient Safety: A Survey

INTRODUCTION

Meaningful conversations about diagnostic errors require safety cultures where clinicians are comfortable discussing errors openly. However, clinician comfort discussing diagnostic errors publicly and barriers to these discussions remain unexplored. We compared clinicians' comfort discussing diagnostic errors to other medical errors and identified barriers to open discussion.

METHODS

Pediatric clinicians at 4 hospitals were surveyed between May and June 2018. The survey assessed respondents' comfort discussing medical errors (with varying degrees of system versus individual clinician responsibility) during morbidity and mortality conferences and privately with peers. Respondents reported the most significant barriers to discussing diagnostic errors publicly. Poststratification weighting accounted for nonresponse bias; the Benjamini-Hochberg adjustment was applied to control for false discovery (significance set at P < 0.018).

RESULTS

Clinicians (n = 838; response rate 22.6%) were significantly less comfortable discussing all error types during morbidity and mortality conferences than privately (P < 0.004) and significantly less comfortable discussing diagnostic errors compared with other medical errors (P < 0.018). Comfort did not differ by clinician type or years in practice; clinicians at one institution were significantly less comfortable discussing diagnostic errors compared with peers at other institutions. The most frequently cited barriers to discussing diagnostic errors publicly included feeling like a bad clinician, loss of reputation, and peer judgment of knowledge base and decision-making.

CONCLUSIONS

Clinicians are more uncomfortable discussing diagnostic errors than other types of medical errors. The most frequent barriers involve the public perception of clinical performance. Addressing this aspect of safety culture may improve clinician participation in efforts to reduce harm from diagnostic errors.

Updates to referring clinicians regarding critically ill children admitted to the pediatric intensive care unit: a state-wide survey

Background Front-line clinicians are expected to make accurate and timely diagnostic decisions before transferring patients to the pediatric intensive care unit (PICU) but may not always learn their patients' outcomes. We evaluated the characteristics of post-transfer updates received by referring clinicians regarding PICU patients and determined preferences regarding content, delivery, and timing of such updates. Methods We administered an electronic cross-sectional survey to Iowa clinicians who billed for ≥5 pediatric patients or referred ≥1 patient to the University of Iowa (UI) PICU in the year before survey administration. Results One hundred and one clinicians (51 non-UI, 50 UI-affiliated) responded. Clinicians estimated that, on average, 8% of pediatric patients they saw over 1 year required PICU admission; clinicians received updates on 40% of patients. Seventy percent of UI clinicians obtained updates via self-initiated electronic record review, while 37% of non-UI clinicians relied on PICU communication (p = 0.013). Clinicians indicated that updates regarding diagnoses/outcomes will be most relevant to their practice. Among clinicians who received updates, 13% received unexpected information; 40% changed their practice as a result. Conclusions Clinicians received updates on less than half of the patients they referred to a PICU, although such updates could potentially influence clinical practice. Study findings will inform the development of a formal feedback system from the PICU to referring clinicians.

Perspectives from the other side of the screen: how clinicians and radiologists communicate about diagnostic errors

Background

Miscommunication amongst providers is a major factor contributing to diagnostic errors. There is a need to explore the current state of communications between clinicians and diagnostic radiologists. We compare and contrast the perceptions, experiences, and other factors that influence communication behaviors about diagnostic errors between clinicians and radiologists.

Methods

A survey with questions addressing (1) communication around diagnostic error, (2) types of feedback observed, (3) the manner by which the feedback is reported, and (4) length of time between the discovery of the diagnostic error and disclosing it was created and distributed through two large academic health centers and through listservs of professional societies of radiologists and clinicians.

Results

A total of 240 individuals responded, of whom 58% were clinicians and 42% diagnostic radiologists. Both groups of providers frequently discover diagnostic errors, although radiologists encounter them more frequently. From the qualitative analysis, feedback around diagnostic error included (1) timeliness of error, (2) specificity in description or terminology, (3) collegial in delivery, and (4) of educational value through means such as quality improvement.

Conclusions

Clinicians and radiologists discover diagnostic errors surrounding the interpretation of radiology images, although radiologists discover them more frequently. There is significant opportunity for improvement in education and practice regarding how radiologists and clinicians communicate as a team and, importantly, how feedback is given when an error is discovered. Educators and clinical leaders should consider designing, implementing, and evaluating strategies for improvement.
