RESUMO

OBJECTIVE: To describe a new method of 3D interactive modeling which integrates images obtained by separate SPET and multi slice computed tomography (MSCT) modalities using an original software in order to better localize SNL in BC patients. SUBJECTS AND METHODS: We used technetium-99m-colloid rhenium sulphate for identifying SNL in seven patients with BC. Markers were made of lead pearls wrapped with cotton wool soaked in 99mTc-pertechnetate and placed on the skin of the patients forming of a triangle. Using an original software, two separate 3D models were made after SPET and MSCT imaging and then merged into a hybrid 3D model which enabled precise visualization and localization of the SNL. RESULTS: In all cases the position of the SNL established by our method was successfully verified using a gamma probe. Duration of SNL identification and extirpation were significantly reduced in less than 10 minutes per patient. The reproducibility of this method was confirmed by precise identification and biopsy of the SNL. CONCLUSION: We found this integrated SPET/MSCT 3D model to be much faster and easier to use as compared with the "classic" method, which was based on a radioactivity detection probe. In addition, our method was reproducible, accurate and of low cost. In other words, the method described in this paper could be very useful for health facilities with modest budget, because it obviates the need for buying expensive integrated SPET/MSCT hybrid imaging systems while detecting SNLs more accurately and in shorter time.

RESUMO

BACKGROUND: Serbia, as the largest market of the Western Balkans, has entered socioeconomic transition with substantial delay compared to most of Eastern Europe. Its health system reform efforts were bold during the past 15 years, but their results were inconsistent in various areas. The two waves of global recession that hit Balkan economies ultimately reflected to the financial situation of healthcare. Serious difficulties in providing accessible medical care to the citizens became a reality. A large part of the unbearable expenses actually belongs to the overt prescription of pharmaceuticals and various laboratory and imaging diagnostic procedures requested by physicians. Therefore, a broad national survey was conducted at all levels of the healthcare system hierarchy to distinguish the ability of cost containment strategies to reshape clinician's mindsets and decision-making in practice. AIMS: Assessment of healthcare professionals' judgment on economic consequences of prescribed medical interventions and evaluation of responsiveness of healthcare professionals to policy measures targeted at increasing cost-consciousness. STUDY DESIGN: Cross-sectional study. METHODS: A nationwide cross-sectional survey was conducted through a hierarchy of medical facilities across diverse geographical regions before and after policy action, from January 2010 to April 2013. In the middle of the observed period, the National Health Insurance Fund (RFZO) adopted severe cost-containment measures. Independently, pharmacoeconomic guidelines targeted at prescribers were disseminated. Administration in large hospitals and community pharmacies was forced to restrict access to high budget-impact medical care. Economic Awareness of Healthcare Professionals Questionnaire-29 (EAHPQ-29), developed in Serbian language, was used in face-to-face interviews. The questionnaire documented clinician's attitudes on: Clinical-Decision-Making-between-Alternative-Interventions (CDMAI), Quality-of-Health-Care (QHC), and Cost-Containment-Policy (CCP). The authors randomly and anonymously recruited 2000 healthcare experts, with a total of 1487 responding; after eliminating incomplete surveys, 649 participants were considered before and 651 after policy intervention. RESULTS: Dentists (1.195±0.560) had a higher mean CDMAI score compared to physicians (1.017±0.453). The surgical group compared to the internist group had a higher total EAHPQ-29 score, CCP score and CDMAI score. Policy intervention had a statistically significant negative impact on the QHC score (F=4.958; df=1; p=0.027). There was no substantial impact of policy interventions on professional behavior and judgment with regard to the CDMAI, CCP, and total EAHPQ-29 scores. CONCLUSION: Although cost savings were forcibly imposed in practice, the effects on clinical decision-making were modest. Clinicians' perceptions of quality of medical care were explained in a less effective manner due to the severely constrained resources allocated to the providers. This pioneering effort in the Balkans exposes the inefficiency of current policies to expand clinicians' cost consciousness.

RESUMO

OBJECTIVE: Current radiation therapy capacities in Serbia and most of Eastern Europe are heavily lagging behind population needs. The primary study aim was assessment of direct costs of cancer medical care for patients suffering from cancer with assigned radiotherapy-based treatment protocols. Identification of key cost drivers and trends during 2010-2013 comparing brachytherapy and teleradiotherapy was a secondary objective of the study. METHODS: Retrospective, bottom-up database analysis was conducted on electronic discharge invoices. Payer's perspective has been adopted with a 1-year long time horizon. Total sample size was 2544 patients during a 4-years long observation period (2010-2013). The sample consisted of all patients with confirmed malignancy disorder receiving inpatient radiation therapy in a large university hospital. RESULTS: Diagnostics and treatment cost of cancer in the largest Western Balkans market of Serbia were heavily dominated by radiation therapy related direct medical costs. Total costs of care as well as mean cost per patient were steadily decreasing due to budget cuts caused by global recession. The paradox is that at the same time the budget share of radiotherapy increased for almost 15% and in value-based terms for €109 per patient (in total €109,330). Second ranked cost drivers were nursing care and imaging diagnostics. Costs of high-tech visualizing examinations were heavily dominated by nuclear medicine tests. CONCLUSION: The budget impact of radiation oncology to the large tertiary care university clinics of the Balkans is likely to remain significant in the future. Brachytherapy exhibited a slow growth pattern, while teleradiotherapy remained stable in terms of value-based turnover of medical services. Upcoming heavy investment into the national network of radiotherapy facilities will emphasize the unsatisfied needs. Huge contemporary budget share of radiotherapy coupled with rising cancer prevalence brings this issue into the hot spot of the ongoing cost containment efforts by local governments.

RESUMO

OBJECTIVE: Assessment of costs matrix and patterns of prescribing of radiology diagnostic, radiation therapy, nuclear medicine, and interventional radiology services. Another aim of the study was insight into drivers of inappropriate resource allocation. METHODS: An in-depth, retrospective bottom-up trend analysis of services consumption patterns and expenses was conducted from the perspective of third-party payer, for 205,576 inpatients of a large tertiary care university hospital in Serbia (1,293 beds) from 2007 to 2010. RESULTS: A total of 20,117 patients in 2007, 17,436 in 2008, 19,996 in 2009, and 17,579 in 2010 were radiologically examined, who consumed services valued at €2,713,573.99 in 2007, €4,529,387.36 in 2008, €5,388,585.15 in -2009, and €5,556,341.35 in 2010. CONCLUSIONS: The macroeconomic crisis worldwide and consecutive health policy measures caused a drop in health care services diversity offered in some areas in the period 2008 to 2009. In spite of this, in total it increased during the time span observed. The total cost of services increased because of a rise in overall consumption and population morbidity. An average radiologically examined patient got one frontal chest graph, each 7th patient got an abdomen ultrasound examination, each 19th patient got a computed tomography endocranium check, and each 25th patient got a head nuclear magnetic resonance. Findings confirm irrational prescribing of diagnostic procedures and necessities of cutting costs. The consumption patterns noticed should provide an important momentum for policymakers to intervene and ensure higher adherence to guidelines by clinicians.
