Imaging activity possibly signalling missed diagnostic opportunities in bladder and kidney cancer: a longitudinal data-linkage study using primary care electronic health records.
Sub-optimal use or interpretation of imaging investigations prior to diagnosis of certain cancers may be associated with less timely diagnosis, but pre-diagnostic imaging activity for urological cancer is unknown. In this study, the investigators analysed linked data derived from primary and secondary care records and cancer registration to evaluate the use of clinically relevant imaging tests pre-diagnosis, in patients with bladder and kidney cancer diagnosed in 2012-15 in England.

Appropriateness of cardiac stress test use among primary care physicians and cardiologists in the United States.
In this study, the researchers used nationally-representative data to examine differences in appropriate use of cardiac stress testing between cardiologists and primary care physicians (PCPs) in the US. Using permissive criteria to determine appropriateness, they found that primary care physicians are more likely to order or perform a rarely appropriate cardiac stress test than cardiologists.

Association of early imaging for back pain with clinical outcomes in older adults.
This study compared function and pain at the 12-month follow-up visit among older adults who received early imaging with those who did not receive early imaging after a new primary care visit for back pain without radiculopathy. It found that early imaging was not associated with better 1-year outcomes. The researchers concluded that the value of early diagnostic imaging in older adults for back pain with radiculopathy is uncertain.
