Higher Medicare spending on imaging and lab services after primary care physician group vertical integration.
This study looked at the impact of direct ownership of physician practices by hospitals and health systems (vertical integration) on Medicare spending for imaging and lab services. A 100% sample of 2013-16 Medicare fee-for-service claims data was examined to determine if vertical integration was associated with changes in site of care and Medicare reimbursement rates for ten common diagnostic imaging and laboratory services. After vertical integration, the monthly number of diagnostic imaging tests per 1,000 attributed beneficiaries increased in a hospital setting by 26.3 per 1000, and the number performed in a nonhospital setting decreased by 24.8 per 1,000. Hospital-based laboratory tests increased by 44.5 per 1,000 and non-hospital-based laboratory tests decreased by 36.0 per 1,000. Average Medicare reimbursement rose by $6.38 for imaging tests and $0.57 for laboratory tests. This translates to $40.2 million increase for imaging and $32.9 million increase for laboratory tests in Medicare spending for the study period.

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.

Comparing the rates of low-value back images ordered by physicians and nurse practitioners for Medicare beneficiaries in primary care.
This study measures the rates of low-value back images ordered by primary care physicians and nurse practitioners for Medicare beneficiaries, and there was no detectable difference between the two groups in 2012 and 2013.

Variation among primary care physicians in the use of imaging for older patients with acute low back pain.
The authors sought to estimate the variation among primary care providers (PCPs) in the use of diagnostic imaging for older patients with non-specific acute low back pain. They used Texas Medicare claims data and tracked whether each patient received lumbar imaging within 4 weeks of the initial visit. They found that the specific physician seen by a patient accounted for 25 % of the variability in whether imaging was performed and that the use of imaging by individual physicians was stable over time.

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.
