“…Our results showing an increase in emergency room visits, MRI and CT scans, and specialist care visits correspond with this body of literature. The increase in the use of MRI and CT scans following the market entry is also similar to studies conducted in Ontario 25 and Manaus 26 . Excess use of diagnostic procedures (such as MRI and CT scans) may be derived from defensive medicine, a desire to respond to patient demand requests, or a lack of communication between groups of doctors from different specialties such as general physicians, radiologists, and orthopedic specialists 25 .…”

Our aim was to examine the influence of the market entry of Samson Assuta Ashdod University Hospital on community and hospital-based healthcare utilization (HCU). A retrospective study was conducted among Maccabi Health Services enrollees in the regions of Ashdod (n = 94,575) and Netanya (control group, n = 80,200) before and after this market entry. Based on difference-in-differences framework, we examined the change in HCU of Ashdod region’s enrollees compared to the control group and following the market entry using multivariable generalized estimating equations models. Our results revealed that, as hypothesized, after the market entry and compared to the control group, there was a 4% increase in specialists visits not requiring referral (RR = 1.04, 95% CI 1.03–1.06, p < 0.001), a 4% increase in MRI and CT scans (RR = 1.04, 95% CI 1.01–1.08, p = 0.022), and a 33% increase in emergency room visits (RR = 1.33, 95% CI 1.29–1.38, p < 0.001). Unexpectedly, no changes were observed in the number of hospital admissions (RR = 1.05, 95% CI 0.97–1.14, p = 0.250), and hospitalization days (RR = 0.99, 95% CI 0.94–1.04, p = 0.668). Moreover, and unexpectedly, there was a 1% decrease in primary care physician visits (RR = 0.99, 95% CI 0.98–1.00, p = 0.002), a 11% decrease in specialists visits requiring a referral (RR = 0.89, 95% CI 0.86–0.91, p < 0.001), and a 42% decrease in elective surgeries (RR = 0.58, 95% CI 0.55–0.60, p < 0.001). We conclude that this market entry was not translated to an increase in utilization of all services. The unique model of maintaining the continuity of care that was adopted by the hospital and patients’ loyalty may led to the unique inter-relationship between the hospital and community care.

Summary Introduction Back pain is a common global disorder and magnetic resonance imaging (MRI) is one method of assessing its cause. The lack of official and general clinical guidelines is the cause of inadequate supervision of lumbar MRI prescriptions. The goal of this research was to analyze inappropriate lumbar MRI prescriptions and the resulting economic burden on individuals. Method This is a descriptive‐analytical study carried out on a sample of 614 patients who visited four hospitals in Tehran. The appropriateness or inappropriateness of the MRI prescriptions was determined using clinical guidelines and a questionnaire based on previous studies. The economic burden created by inappropriate prescriptions for MRIs was determined after calculating the total direct and indirect costs. Findings The total MRI prescription cost paid by the study sample was $26 071, and the cost of inappropriate prescriptions was $10 310. The MRI prescription rate had a significant relationship with gender, age, education, employment, primary insurance type, and supplemental health insurance. Conclusion The research findings revealed relatively high rates of inappropriate MRI prescriptions in the private and public sectors. Hence, policymakers should design, create, and develop clinical guidelines and enforce the policies and rules to decrease inappropriate MRI prescriptions.

They apply the data from the period beginning in the year 1998 and ending in the year 2004, which they use computed tomographs and magnetic resonance imaging scanners as a part of the health system plans during.…”

The aim of the study is to investigate the relationship between the spatial distribution of the selected medical equipment and the preventable mortality rate in the regions of the Slovak Republic. The main analytical approach is carried out through the cluster analysis based on a Euclidean distance technique in order to get similarity of the administrative divisions in form of a district and a pseudot2 approach aimed at the determination of a number of the districts in a cluster. A number of medical equipment had a rising tendency from the year 2008. The most extreme position according to a localisation distribution of the computed tomographs and the magnetic resonance imaging scanners is held by the Košice IV District at the level of 7.50630. From an angle of view of the preventable mortality, the Piešťany District holds the most extreme position peaking at the level of 10.97969 for the female sex and the Kežmarok District with the value of 9.44088. The study has the significant dissemination outputs for health policy interventions, especially to draw up regional health plans for computed tomography and magnetic resonance imaging deployment, mainly in locations with a high preventable mortality rate for both sexes.
