Regional health care profiles - an improved method for generating case studies on the catchment areas of envisaged primary health care units in Austria: a report to the InfAct Joint Action.

BACKGROUND: The recent Austrian Primary Care Act established new primary health care units (PHCUs) and obliged them to draw up a "care strategy" specifying their focal care tasks and objectives and emphasizing the health care needs of the population in their catchment area with its specific local health and epidemiological profile. The main purpose of these care strategies is thus to ensure that care-providers meet the local needs, but they also provide a rationale for evaluation and organizational development. To assist new PHCUs in establishing care strategies it was necessary to develop a method for automatically generating comprehensive local case studies for any freely definable location in Austria. RESULTS: We designed an interactive report generator capable of producing location-specific regional health care profiles for a PHCU located in any of Austria's 2122 municipalities and of calculating the radius of its catchment area (defined by different levels of maximum car-travelling times). The reports so generated, called "regional health care profiles for primary health care" (RHCPs/PHC), are in comprehensive PDF report format. The core of each report is a set of 35 indicators, classified under five health and health service domains. The reports include an introductory text, definitions, a map, a graphic and tabular presentation of all indicator values, including information on local, supra-regional and national value distribution, a ranking, and numbers of service providers (e.g. pharmacies, surgeries, nursing homes) located within the catchment area. CONCLUSIONS: The RHCPs/PHC support primary health care planning, efforts to improve care-effectiveness, and strategic organizational development by providing comprehensive information on the health of the population, the utilization of health services and the health care structures within the catchment area. In addition to revealing the scope and nature of the health care needed, they also provide information on what public health approaches are necessary. RHCPs/PHC for different locations have already been distributed to numerous stakeholders and primary health care providers in Austria.

Diagnostic Reference Levels for nuclear medicine imaging in Austria: A nationwide survey of used dose levels for adult patients.

PURPOSE: To assess dose levels in routine nuclear medicine (NUC) procedures in Austria as a prior to a legislative update of the National Diagnostic Reference Levels (NDRL). METHOD: As part of a nationwide survey of common NUC-examinations between June 2019 and November 2019, data sets were collected from 33 Austrian hospitals with NUC equipment. All hospitals were asked to report the NUC imaging devices in use (model, type, year of manufacture, detector material, collimators), the standard protocol parameters for selected examinations (standard activity, collimator, average acquisition time, reconstruction type, use of time-of-flight) and to report data from 10 representative examinations (e.g. injected activity, weight), incl. the most common NUC-examinations for planar imaging/SPECT and PET. Median/mean values for injected activity were calculated and compared to current Austrian and international NDRL. A Pearson correlation coefficient was computed comparing different variables. RESULTS: In total, all 33 hospitals (100% response rate) reported data for this study for 60 SPECT devices, 21 PET/CT devices and 23 scintigraphy devices. Fixed activity values for scintigraphy/SPECT and PET were employed by about 90% and 56% of the hospitals, respectively. The most widely performed examinations for scintigraphy/SPECT are bone imaging, thyroid imaging, renal imaging (with MAG3/EC) and lung perfusion imaging (in 88% of the hospitals) and F-18 FDG-PET studies for oncology indications (in 100% of the hospitals). Significant correlations were found for patient weight and injected activity (scintigraphy/SPECT), use of iterative reconstruction and injected activity (PET) as well as size of field-of-view and injected activity (PET). CONCLUSIONS: The reported injected activity levels were comparable to those in other countries. However, for procedures for which NDRL exist, deviations in injected activities of >20% compared to the NDRL were found. These deviations are assumed to result mainly from advances in technology but also from deviations between NDRL and prescribed activities as given in the information leaflets of the radiopharmaceuticals.

The long-term outcome of urethrotomy for primary urethral strictures: a population-based analysis.

OBJECTIVE: To determine the long-term outcome of endoscopic urethrotomy for primary urethral strictures based on a population-based approach. PATIENTS AND METHODS: We analysed a nationwide database of all patients with urethral stricture disease who underwent endoscopic urethrotomy as a primary intervention between January 2006 and December 2007. All patients were followed individually for 7-9 years. Frequencies and types of surgical re-interventions were documented. Repeat surgical interventions were stratified into three treatment types: urethrotomy, urethroplasty, and end-to-end urethral anastomosis. RESULTS: A total of 1203 men underwent urethrotomy during the index period. The median (SD, range) patient age was 63 (15.7, 20-85) years. A total of 136 patients (11%) died during follow-up. Within the follow-up period, 932 patients (78%) received no further surgical re-intervention for recurrent disease, and 176 patients (14.6%) required one, 53 (4.5%) two, and 41 (3.4%) three or more procedures. The mean number of re-interventions was 1.5/patient and the lowest re-intervention rate was in patients aged ≥80 years (13.9%). In 236 cases (68%) at least one repeat urethrotomy was performed. An open reconstruction was performed in 87 cases (32%), with urethroplasty in 21 patients (24%), and end-to-end anastomosis in 66 patients (76%). The mean interval until re-intervention was 29.5 months. CONCLUSIONS: This long-term population-based study suggests that the invasive re-treatment rate in men following initial urethrotomy is 22% within 8 years and lowest in the advanced age cohort.

Diagnostic Reference Levels for computed tomography in Austria: A 2018 nationwide survey on adult patients.

PURPOSE: To define National Diagnostic Reference Levels (NDRLs) for computed tomography (CT) for Austria on adult patients. METHOD: In the course of a nationwide survey on common CT-examinations between June 2018 and November 2018, datasets were requested from all Austrian hospitals and radiology centers with CT-scanners. All facilities were asked to report a minimum sample of 10 representative dose length product (DLP) values per examination type and CT-scanner, including information about scan sequences, iterative reconstruction (IR) algorithms and, if available, patient data. Examination types included into the survey were the most common CT-indications for the anatomic regions head, facial bones, thorax, abdomen and pelvis. 3rd quartiles of CT-scanner median DLPs were calculated and compared to Austrian and international NDRLs. RESULTS: For 76 % of all operating CT-scanners, DLP data was submitted varying from 13 to 172 scanners per examination type. Mean year of manufacture of the CT-scanners was 2011, ranging from 2003 to 2018. In 66 % of the examinations, IR was used. 3rd quartile is on average 21 % lower for scanners using IR algorithms as opposed to scanners or protocols not using IR. In the case of gender differences, the DLP for females is on average 17 % lower than for males. CONCLUSIONS: The new recommendations for CT NDRLs for Austria based on a nationwide survey are on average 13 % lower than the current Austrian NDRLs and correspond well to recent German and Swiss NDRLs. 3rd quartiles for DLP are dependent on gender, the use of IR and year of manufacture of the CT-scanners.

Medical radiation exposure from radiological and interventional procedures in Austria.

BACKGROUND: The aim of the study was to systematically evaluate the frequency of diagnostic and interventional X­ray procedures and the corresponding population exposure in Austria. DATA AND METHODS: A methodology based on 107 selected procedures was adopted in accordance with European Commission recommendations. Frequencies were calculated based on an Austrian nationwide standardized database for the outpatient and inpatient sectors. The collective effective dose was estimated by linking the procedure frequencies to results from previous studies on doses per procedure and correction factors from the European Commission. RESULTS: In Austria, 1468 diagnostic and interventional X­ray procedures per 1000 inhabitants were conducted in 2015. Plain radiography procedures were performed most frequently, with approximately 40% being dental radiographs. The estimated extrapolated collective effective dose for 2015 was approximately 12,890 man-sievert (1.5 mSv per head). Although computed tomography only constitutes about 11% of the total number of procedures, its contribution to the collective effective dose is by far the largest at 74%, followed by plain radiography at almost 10%. CONCLUSION: This study provides a comprehensive estimate of procedure frequencies in Austria based on annually available, routinely collected data and of the corresponding collective effective dose. The results show that the frequency of computed tomography in Austria more than doubled within the last 14 years and is high compared to Germany and Switzerland. As in other countries, computed tomography is the largest contributor to the collective effective dose, identifying it as an area that deserves special attention for dose optimization.

Diagnostic Reference Levels for conventional radiography and fluoroscopy in Austria: Results and updated National Diagnostic Reference Levels derived from a nationwide survey.

OBJECTIVE: Evaluation and updating of Austrian National Diagnostic Reference Levels (NDRLs). METHODS: A nationwide survey on common conventional radiography and fluoroscopy examinations was conducted. In line with Austrian radiation protection standards, all relevant Austrian hospitals and radiology offices/centers were asked to report a minimum sample of 10 representative dose-area product (DAP) values together with patient weight and fluoroscopy time, if applicable. Examinations included for conventional radiography were skull, chest, abdomen, pelvis, lumbar spine and bedside chest x-ray, for fluoroscopy barium enema (single and double contrast) and swallowing (video). Participants were invited via e-mail, followed up by reminders to increase participation rates. Plausibility checks were performed to increase data quality. 3rd quartiles of facility median and mean DAP were calculated and compared to Austrian and international NDRLs. RESULTS: 59% of invited facilities submitted DAP data, 43% submitted additional data on patient weight and 41% on fluoroscopy time. DAP case numbers varied from 1005 to 2121 for conventional radiography and from 182 to 1380 for fluoroscopy. Average patient weight was 75 kg for conventional radiography and 77 kg for fluoroscopy. CONCLUSION: 3rd quartiles derived from the survey are substantially lower than the old Austrian NDRLs (valid till early 2018). Since 3rd quartiles correspond well to European NDRLs, the update would be in accordance with European DRL harmonisation efforts.

Reoperation Rates and Mortality After Transurethral and Open Prostatectomy in a Long-term Nationwide Analysis: Have We Improved Over a Decade?

OBJECTIVE: To assess long-term reoperation rates and mortality after transurethral resection of the prostate (TURP) and open prostatectomy (PE) as therapy for lower urinary tract symptoms due to benign prostatic enlargement. METHODS: The present study analyzes a nationwide database of all patients who underwent TURP/open PE during 2002-2006 and who were followed up for 8 years. Actuarial cumulative incidences of reoperation (TURP, urethrotomy, bladder neck incision) and death were calculated. Data were provided by the Austrian Public Health Institute. This series was compared with a previously published almost equally sized nationwide cohort that underwent surgery during 1992-1996 in Austria. RESULTS: Between 2002 and 2006, a total of 21,674 patients underwent TURP (n = 20,388) or open PE (n = 1,286). At 8 years, the re-TURP rate after primary TURP was 8.3% vs 4.3% after open PE. The re-TURP rate was higher in the 80+ cohort. The overall endourological reintervention rate at 8 years was 12.7% for TURP and 8.8% for open PE. Reintervention rates did not improve compared with the 1992-1996 series. The 30-day in-hospital mortality rate was 0.1% for TURP and 0.2% for open PE. Mortality rates improved by approximately 20% compared with the 1992-1996 series. CONCLUSION: In Austria, TURP rates remained stable between 1992 and 2006, paralleled by a 50% decline of open PE. Within a decade, mortality rates declined by 20%, yet reintervention rates remained unchanged.
