A web-survey assessed attitudes toward evidence-based practice among psychotherapists in Austria.

Evidence-based practice (EBP) means integrating the best available scientific evidence with clinical experience and patient values. Although perceived as important by many psychotherapists, there still seems to be reluctance to use empirically supported therapies in clinical practice. We aimed to assess the attitudes of psychotherapists in Austria toward EBP in psychotherapy as well as factors influencing the implementation of EBP. We conducted an online survey. To investigate attitudes toward EBP, we used two subscales ("Limitations" and "Balance") of a translated and validated short version of the Evidence-Based Practice Attitude Scale-36 (EBPAS-36). Participants provided perceived barriers and facilitators as answers to open-ended questions. We analyzed the responses mainly using descriptive statistics. Open answers were analyzed using a thematic analysis. In total, 238 psychotherapists completed our survey (mean age 51.0 years, standard deviation [SD] = 9.9, 76.9% female). Psychotherapists scored on average 2.62 (SD = 0.89) on the reversed EBPAS-36 subscale "Limitations," indicating that the majority do not perceive EBP as limiting their practice as psychotherapists. They scored 1.43 (SD = 0.69) on the reversed EBPAS-36 subscale "Balance," indicating that psychotherapists on average put a higher value on the art of psychotherapy than on evidence-based approaches. Organizational factors such as lack of time and access to research studies as well as negative attitudes toward research and a lack of skills and knowledge kept respondents from implementing EBP. Our study highlights that EBP is still not very popular within the psychotherapy community in Austria. The academization of psychotherapy training might change this in the future.

Selection of animal bone surrogate samples for orthopaedic screw testing based on human radius CT-derived bone morphology.

Animal bones are commonly used to test the mechanical competence of bone screws since they are easier to obtain compared to human bones. Nevertheless, selecting an appropriate animal sample that correctly represents the human bone architecture where the screw is implanted is frequently overlooked. This study presents a protocol for bone sample selection for screw mechanical testing based on a characterization of the local CT-derived bone morphology. For this, 36 human radii were used to quantify the local peri-implant bone morphology of 360 osteosynthesis screws, 10 per bone, whose implantation site and depth were fully known. A cylindrical volume of interest was created along the screw path and used to measure the local morphology. With this, 10 average peri-implant bone morphologies were defined. Additionally, two animal models, pig, and sheep, were selected and used as potential sample sources. From each model, six bones were selected for analysis. Based on a surface mesh of each bone a computational algorithm was created to automatically extract cylindrical probes in several locations from which the local bone morphometry was calculated. A multi-parametric bone similarity score was developed and used to compare the local morphology of each animal bone to that of the human average peri-implant bone morphology. The score was then mapped to the surface of the bone thus allowing to visually identify regions on the animal bone with human-like bone morphology. By using this methodology, the use of human bones can be avoided since samples with human-like bone morphologies can be found on animal bones. This is not only useful in cases where strict ethical constrains must be fulfilled, but also in studies where the relationship between morphology and screw competence is to be studied, something that is hard to replicate with commercially available synthetic alternatives.

[Intracranial hemorrhage masquerading as STEMI]. / EKG-Veränderungen bei intrakranieller Blutung.

A 56-year-old woman was found unconscious and promptly intubated. The electrocardiogram showed ST elevations in I, aVL, V1-V4. Thus, lysis therapy was performed. After admission to the intensive care unit, the patient was reassessed. Laboratory evaluation confirmed elevated troponin T. However, coronary angiography showed no coronary artery disease, whereas cerebral computed tomography revealed massive intracranial hemorrhage without neurosurgical treatment option. Brain death was confirmed after 54 hours. This case highlights electrocardiographic changes in intracranial hemorrhage that may be masquerading as STEMI.

Early changes in biochemical markers of bone formation during teriparatide therapy correlate with improvements in vertebral strength in men with glucocorticoid-induced osteoporosis.

UNLABELLED: Changes of the bone formation marker PINP correlated positively with improvements in vertebral strength in men with glucocorticoid-induced osteoporosis (GIO) who received 18-month treatment with teriparatide, but not with risedronate. These results support the use of PINP as a surrogate marker of bone strength in GIO patients treated with teriparatide. INTRODUCTION: To investigate the correlations between biochemical markers of bone turnover and vertebral strength estimated by finite element analysis (FEA) in men with GIO. METHODS: A total of 92 men with GIO were included in an 18-month, randomized, open-label trial of teriparatide (20 µg/day, n = 45) and risedronate (35 mg/week, n = 47). High-resolution quantitative computed tomography images of the 12th thoracic vertebra obtained at baseline, 6 and 18 months were converted into digital nonlinear FE models and subjected to anterior bending, axial compression and torsion. Stiffness and strength were computed for each model and loading mode. Serum biochemical markers of bone formation (amino-terminal-propeptide of type I collagen [PINP]) and bone resorption (type I collagen cross-linked C-telopeptide degradation fragments [CTx]) were measured at baseline, 3 months, 6 months and 18 months. A mixed-model of repeated measures analysed changes from baseline and between-group differences. Spearman correlations assessed the relationship between changes from baseline of bone markers with FEA variables. RESULTS: PINP and CTx levels increased in the teriparatide group and decreased in the risedronate group. FEA-derived parameters increased in both groups, but were significantly higher at 18 months in the teriparatide group. Significant positive correlations were found between changes from baseline of PINP at 3, 6 and 18 months with changes in FE strength in the teriparatide-treated group, but not in the risedronate group. CONCLUSIONS: Positive correlations between changes in a biochemical marker of bone formation and improvement of biomechanical properties support the use of PINP as a surrogate marker of bone strength in teriparatide-treated GIO patients.

Preventive service use and Medicaid managed care in New York City.

OBJECTIVE: To examine the effect of managed care enrollment on the use of preventive services among New York City's Medicaid population. STUDY DESIGN: An analysis of survey results from a sample of Medicaid beneficiaries in managed care plans and in traditional Medicaid. METHODS: This study is based on a 1994 survey of 1038 Medicaid beneficiaries enrolled in any of 5 managed care plans and a comparison group of 410 beneficiaries in traditional Medicaid in New York City. The survey data are used to examine the effect of managed care on the self-reported use of Pap smears, mammograms, and infant immunizations. We performed bivariate analysis to compare the use of preventive services between managed care enrollees and beneficiaries in traditional Medicaid. We also used multivariate logistic analysis to explore this comparison, controlling for factors that may confound the relationship. RESULTS: Medicaid beneficiaries in managed care were no more or less likely to receive infant immunizations, Pap smears, or mammograms than those in the traditional Medicaid program. CONCLUSIONS: Our analysis suggests that Medicaid managed care and the traditional program performed the same in getting appropriate preventive services to beneficiaries.

Women in New York City's Medicaid program: a report on satisfaction, access, and use.

This article analyzes the experiences of women in New York City's Medicaid program regarding their satisfaction with, access to, and use of medical care during an early phase of a managed care enrollment initiative. Data for this study are from a 1994 survey of New York City Medicaid beneficiaries (1,221 women) as well as from focus group discussions. Differences in reported satisfaction levels, access, and use between managed care enrollees and conventional Medicaid beneficiaries are examined, as are differences between women in fair and poor health and those in excellent, very good, and good health. Multivariate analyses found that women enrolled in Medicaid managed care overall were significantly more likely to report greater satisfaction with access, interpersonal quality, technical skills, and arrangements for choosing a personal doctor; equivalent use; and better access compared to those in conventional Medicaid. Female managed care beneficiaries who reported worse health, however, were significantly more likely than those in better health to also report less satisfaction in 13 dimensions of medical care. Continued evaluation of Medicaid managed care is warranted, particularly as more vulnerable groups are enrolled.

Evaluation of Medicaid managed care. Satisfaction, access, and use.

OBJECTIVE: To evaluate the effects of managed care on Medicaid beneficiaries' satisfaction with, access to, and use of medical care during early implementation of an enrollment initiative. DESIGN: Cross-sectional survey of a random sample of Medicaid beneficiaries in 5 managed care plans and in the conventional Medicaid program. SETTING: New York, NY. PARTICIPANTS: Adults aged 18 to 64 years who received Medicaid insurance benefits through Aid to Families With Dependent Children or State Home Relief and had been enrolled in a managed care plan or receiving benefits under conventional Medicaid for at least 6 months. Of the 2500 enrollees in managed care plans and the 600 other beneficiaries in conventional Medicaid whom we surveyed, 1038 enrollees and 410 nonenrollees responded. OUTCOME MEASURES: Beneficiaries' ratings of overall satisfaction and 13 dimensions of satisfaction related to access, interpersonal and technical quality, and cost; reports of access, including regular source (location) of care, waiting time for appointment, waiting time in office, and ability to obtain care; and reports of use, including inpatient, emergency department, and ambulatory visits. RESULTS: Compared with beneficiaries in conventional Medicaid, managed care enrollees in general gave higher ratings of satisfaction. The results were not consistent, however, between the proportion who were extremely satisfied and the proportion who were extremely dissatisfied. Managed care enrollees had significantly greater odds of being extremely satisfied (excellent and very good ratings), but fewer differences were statistically significant for levels of extreme dissatisfaction (fair and poor ratings). With regard to access, managed care enrollees had significantly greater odds of having a usual source of care (odds ratio [OR], 2.33) and seeing the same clinician there (OR, 2.72) and had significantly shorter appointment and office waiting times. Managed care and conventional Medicaid beneficiaries reported no significant differences in obtaining or delays in getting needed care and in inpatient or emergency department use. CONCLUSIONS: Medicaid managed care enrollees in New York City reported better access to care and higher levels of satisfaction compared with conventional Medicaid beneficiaries. Differences between these findings and those for privately insured populations highlight the pitfalls of generalizing from other groups to Medicaid for policy purposes. Given growing reliance on consumer satisfaction surveys for clinical and public policy, future research should focus on factors that explain extreme satisfaction vs extreme dissatisfaction. New York State's initiative, which has been associated with careful state and local monitoring, merits continuing evaluation as managed care enrollment grows and may become mandatory.

Medicaid physician payment reform: using the Medicare Fee Schedule for Medicaid payments.

OBJECTIVES: The purpose of this article is to provide estimates of the costs of basing Medicaid physician payment levels on the new resource-based Medicare Fee Schedule. Two possible policy options are considered: setting all Medicaid physician fees at the Medicare Fee Schedule level and setting only office visit fees at the new Medicare levels. METHODS: Data on Medicaid physician fees, use patterns, and the Medicare Fee Schedule are used to develop state-level estimates of expenditure changes under each option. RESULTS: Setting Medicaid rates at the Medicare Fee Schedule level could increase expenditures by $3.2 to $4.1 billion nationally; the other option would result in substantially lower increases in expenditures. Because of the current variations in Medicaid physician fees and in the breadth of eligibility across states, the cost of adopting the Medicare Fee Schedule varies considerably among states. CONCLUSIONS: Adopting the new Medicare Fee Schedule for Medicaid payments, proposed by policy-makers as a way to increase access to appropriate medical care, could double physician expenditures in some states. Adoption of more limited versions of the fee schedule might achieve some access gains at lower costs.

[Mortality and morbidity of newborn infants in intensive care (birth weight less than 1,501 grams)]. / Untersuchungen zur Mortalität und Morbidität intensivgepflegter Frühgeborener (Geburtsgewicht unter 1501 Gramm).

A comparative analysis of the mortality and morbidity of premature infants with a birthweight below 1.501 g, born in the years 1974, 1978 and 1981, is given. The mortality rate has remained unchanged in the years 1974 (when a neonatal intensive care unit was installed at the University Children's Hospital Graz) and 1981 with 33% and 32% respectively. The total number of admissions rose from 36 (1974) to 67 (1978) and 91 (1981). Simultaneously the number of patients, who needed neonatal intensive care increased. Whilst in 1974 only 2 of 24 surviving infants needed artificial ventilation, in 1978 19 of 38 patients had respirator therapy. Despite the increasing severity of neonatal affections the number of severe handicaps caused by perinatal complications remained constantly low with altogether 5 cases in the years 1978 and 1981. Two children had a spastic tetraplegia, two others had a posthaemorrhagic hydrocephalus and one child was blind due to bilateral septic abscesses of the vitreous body. Only two of these children had long time artificial ventilation. Approximately 80% of the surviving children exhibited normal psychomotor development and showed no neurological sequelae. This rate was unchanged in the investigated periods.

Characteristics of optical guided modes in lossy waveguides.

A number of analysis techniques aimed at determining the characteristics of optical guided waves propagating in lossy structures are examined. The exact theory is used as a guide to assess the validity of several approximate methods based on two basic approaches: (a) geometrical optics and (b) perturbation calculations. The limitations of the conventional perturbation techniques are specified. We present a generalized procedure that permits an accurate description of metal boundaries at optical frequencies. In this case, TM modes differ from their TE counterparts by a field buildup near conducting walls and by the existence of an additional surface plasma mode. The dependence of attenuation coefficients on film thickness and mode order are discussed. The use of low-index dielectric buffers to reduce ohmic losses is considered. It is found that, with increasing buffer thickness, TM(N) modes undergo a continuous transformation to become TM(N+1).
