Finding the Needle in the Hay Stack: Population-based Study of Prediagnostic Symptomatic Interval in Children With CNS Tumors.

Central nervous system (CNS) tumors in children are a devastating diagnosis and delay in diagnosis is well documented in the literature. The aim of this study was to document and characterize time to diagnosis of CNS tumors among children 0 to 17 years of age in a pediatric center. A retrospective chart review was conducted of medical records of children with CNS tumors from 2000 to 2016 in British Columbia, Canada and 148 reports were available for review. Average age at diagnosis was 87.8 months (SD=59.7; median=72). One third (30%) were diagnosed after a single visit to a health care provider and 11 (7.7%) after more than 4 visits. Median time to diagnosis (prediagnostic symptomatic interval [PSI]) was 62 days (average 197±341 d; range, 0 to 2047 d). Longest period was time from first symptom to first health care provider visit (PSI1, median 37 d). Tumors in the posterior fossa and symptoms of ataxia or paresis were associated with a significantly shorter PSI. CNS tumors in children continue to pose a diagnostic challenge with variability in time to diagnosis. Our population-based study suggests variability in time to diagnosis with a need for education of families to identify symptoms associated with CNS tumors.

A qualitative study of sign-out processes between primary and on-call residents: relationships in information exchange, responsibility and accountability.

OBJECTIVE: To review a quality improvement event on the process of sign-outs between the primary and on-call residents. DESIGN: A retrospective qualitative study using semi-structured interviews. SETTING: A tertiary academic medical center in Singapore with 283 inpatient Medicine beds served by 28 consultants, 29 registrars, 45 residents and 30 interns during the day but 5 residents and 3 interns at night. PARTICIPANTS: Residents, registrars and consultants. INTERVENTION: Quality improvement event on sign-out. MAIN OUTCOME: Effectiveness of sign-out comprises exchange of patient information, professional responsibility and task accountability. RESULTS: The following process of sign-outs was noted. Primary teams were accountable to the on-call resident by selecting at-risk patients and preparing contingency plans for sign-out. Structured information exchanged included patient history, active problems and plans of care. On-call residents took ownership of at-risk patients by actively asking questions during sign-out and reporting back the agreed care plan. On-call residents were accountable to the primary team by reporting back at-risk patients the next day. CONCLUSION: A structured information exchange at sign-out increased the on-call resident's ability to care for at-risk patients when it was supported by two-way transfers of responsibility and accountability.
