[Performance and costs of outpatient clinics of university hospitals for medical care, teaching, research activities]. / Leistungen und Kosten der Hochschulambulanzen in Forschung, Lehre und Versorgung -- Ergebnisse der Hochschulambulanzenstudie.

BACKGROUND: Outpatient clinics of university hospitals (Hochschulambulanzen) play a significant role in the German health care system. Universities have in contrast to other hospitals the right to implement an outpatient clinic, but the health care services they can render are restricted to clinical research and teaching activities. The university outpatient clinic study evaluates the intensity of medical care, teaching, research activities, and the related costs. METHOD AND DATABASE: 6 university hospitals with 51 outpatient departments in Germany were included. The prospective documentation of consultations was restricted to 800 visits per department. A total of 26,312 consultations with approximately 40,000 diagnoses and 150,000 services were documented. Furthermore, data concerning costs, teaching activities and research facilities were documented. RESULTS: Clinical treatment without any correlation to research or teaching activities amounted to about 81 % of the working time in the outpatient department (research 11 %; teaching 8 %). The primary task of the university outpatient clinics takes up less than 20 % of the working time. The physicians documented that the disease of every fourth visit was in accordance with their main field of research. 6.9 % of the visits were asked to take part in clinical trials, of these 1.25 % were included for the first time, 3.7 % were already included. 6.5 % of the visits were addressed to participate in specific teaching activities. The average total costs per case added up to 149 Euro. No outpatient clinic could cover the total per case costs with the lump sum payments. On the average 31 % of these costs were covered by lump sum payments (without cases concerning research and teaching). CONCLUSION: Treatment in outpatient departments of university clinics is far beyond research and teaching activities required by law. However, the ability of outpatient departments of universities to provide excellent outpatient services should have a more dominant role in the health care system. Therefore access to care should be deregulated for the patients and reimbursement schemes should be adjusted to adjust for the present losses.

Similarities and differences in distortion-product otoacoustic emissions among four FDA-approved devices.

Similarities and differences in distortion-product otoacoustic emissions (DPOAEs) among four Food and Drug Administration (FDA) approved devices were assessed quantitatively. DPOAEs were recorded from 42 adult subjects (84 ears) ranging in age from 19 to 40 years. All subjects had hearing thresholds of 20 dB HL or better for the test frequencies from 0.25 to 8.0 kHz and normal acoustic immittance findings. DPOAEs were collected in a quiet non-sound-treated room. DPOAE measurement parameters included an f2/f1 ratio of approximately 1.2, with f1 at 65 dB SPL (L1) and f2 at 55 dB SPL (L2). There were no significant differences in the mean emissions levels among the four devices. This investigation showed that validity criteria, pass criteria, and strategies for DPOAE measurements interact to produce varying pass and refer results. However, when DPOAEs are obtained with consistent validity criteria, pass criteria, and strategies for measurement, the results are remarkably consistent.

Impact of a school-based intervention on access to healthcare for underserved youth.

PURPOSE: To determine whether a multidimensional school-based intervention, which included physical and mental health services, increased adolescents' use of needed medical care and preventive care and decreased emergency room use. METHODS: A total of 2832 seventh- through twelfth-grade students in six public urban intervention schools and 2036 students in six demographically matched comparison schools completed a previously validated survey regarding health status and healthcare utilization in spring 1998 and 1999. Bivariate analyses examined the association between intervention status and Year 1/Year 2 outcomes. The multifaceted intervention included programs such as anger management groups, substance abuse prevention, tutoring, home visits, and enhanced school health services. Stepwise multivariate logistic models tested differences between the intervention and comparison groups across years, controlling for potential confounding variables [gender, age, race/ethnicity, maternal education, grade in school, school district (city or county), health status, and chronic health problems]. The interaction term for Group x Year was used to test the effect of the intervention. Multivariable modeling was also used to determine student factors independently associated with healthcare utilization. RESULTS: Respondents had a median age of 15 years, 56% were female, 51% were white, 42% were black, and 34% reported chronic health problems. In both years, over 45% of students in both groups reported not seeking medical care they believed they needed. The proportion with missed care in the intervention schools did not change, whereas the proportion with missed care in the comparison schools increased. Emergency room use decreased slightly in the intervention schools and increased slightly in the comparison schools between Year 1 and Year 2. There were no major changes in healthcare delivery in this area during the year, demonstrating the volatility of adolescents' perceived access to care. Among the student factors, health status, having a chronic condition, and being in a higher grade were independently associated with students' report of not seeking care they believed they needed. CONCLUSION: These results confirm that many adolescents have unmet healthcare needs. Those with poor health status are most likely to report underutilization and unmet needs. These findings underscore the need for comparison groups when evaluating interventions and suggest the need for better understanding of community level changes in perceived healthcare access and use.

School disconnectedness: identifying adolescents at risk.

OBJECTIVE: School connectedness, or the feeling of closeness to school personnel and the school environment, decreases the likelihood of health risk behaviors during adolescence. The objective of this study was to identify factors differentiating youth who do and do not feel connected to their schools in an effort to target school-based interventions to those at highest health risk. METHODS: The study population consisted of all students attending the 7th through 12th grades of 8 public schools. The students were asked to complete a modified version of the in-school survey designed for the National Longitudinal Study of Adolescent Health (Add Health). The school connectedness score (SCS) was the summation of 5 survey items. Bivariate analyses were used to evaluate the association between SCS and 13 self-reported variables. Stepwise linear regression was conducted to identify the set of factors best predicting connectedness, and logistic regression analysis was performed to identify students with SCS >1 standard deviation below the mean. RESULTS: Of the 3491 students receiving surveys, 1959 (56%) submitted usable surveys. The sample was 47% white and 38% black. Median age was 15. Median grade was 9th. The SCS was normally distributed with a mean of 15.7 and a possible range of 5 to 25. Of the 12 variables associated with connectedness, 7 (gender, race, extracurricular involvement, cigarette use, health status, school nurse visits, and school area) entered the linear regression model. All but gender were significant in the logistic model predicting students with SCS >1 standard deviation below the mean. CONCLUSIONS: In our sample, decreasing school connectedness was associated with 4 potentially modifiable factors: declining health status, increasing school nurse visits, cigarette use, and lack of extracurricular involvement. Black race, female gender, and urban schools were also associated with lower SCS. Further work is needed to better understand the link between these variables and school connectedness. If these associations are found in other populations, school health providers could use these markers to target youth in need of assistance.

Quality improvement in a school health program. Results of a process evaluation.

A process evaluation of a school health program designed to improve students' health and educational success is presented. The program included a pediatric nurse practitioner and two nurses placed in three high-risk, urban intervention schools. It is a part of a larger multidimensional pilot intervention project (The Children First Plan). Implemented services and the implementation process are described. Key components for a successful implementation included obtaining buy-in, learning the school culture, defining roles, and keeping a sense of humor. Collaborative efforts among the nursing team, other children-first plan providers, and the school staff improved service delivery. Lack of communication was the primary barrier. In addition, differing philosophies among systems (education, social services, health), problems with referral and feedback, and lack of appropriate providers hampered service delivery. Recommendations for continued program improvement and replication projects are provided.
