Background
Inadequate diagnostic evaluations of breast lumps and rectal bleeding in primary care are an important source of medical errors. Delays appear particularly common in evaluation of rectal bleeding. Comparing pursuit and completion of diagnostic testing for these two conditions within the same practice settings could help highlight barriers and inform interventions.
Objectives
To examine processes undertaken for diagnostic evaluations of breast lumps and rectal bleeding within the same practices and to compare them with regard to (a) the likelihood that diagnostic tests are ordered according to guidelines and (b) the timeliness of order placement and completion.
Design
A retrospective cohort study using explicit chart abstraction methods.
Participants
Three hundred women aged 30–80 presenting with breast lumps and 300 men and women aged 40–80 years presenting with rectal bleeding to 15 academically affiliated primary care practices, 2012–2016.
Main Measures
Rates and timing of test ordering and completion and patterns of visits and communications.
Key Results
At initial presentation, physicians ordered recommended imaging or procedures at higher rates for patients with breast lumps compared to those with rectal bleeding (97% vs. 86% of patients recommended to receive imaging or endoscopy; p < 0.01). Most (90%) patients with breast lumps completed recommended diagnostic testing within 1 month, versus 31% of patients with rectal bleeding (p < 0.01). By 1 year, 7% of patients with breast lumps had not completed indicated imaging, versus 27% of those with rectal bleeding. Patients with breast lumps had fewer subsequent primary care visits related or unrelated to their symptom and had fewer related communications with specialists.
Limitations
The study relied on documented care, and findings may be most generalizable to academically affiliated institutions.
Conclusions
Diagnostic processes for rectal bleeding were less frequently guideline-concordant and timely than those for breast lumps. The largest discrepancies occurred in initial ordering of indicated tests and the timeliness of test completion.
