ABSTRACT
OBJECTIVE: The scales Barthel-Index (BI) and Functional Independence Measure (FIM) are the most frequently used instruments for measurement of outcome in neurological rehabilitation. Both instruments show appropriate psychometric characteristics but there are some limitations for their use in outpatient neurorehabilitation. The "Score of Independence for Neurologic and Geriatric Rehabilitation (SINGER)" was developed to compensate the weaknesses of the established instruments and to facilitate a direct connection to the ICF. The results of the original validation study of the SINGER in an inpatient setting recommended a test of the SINGER also in an outpatient setting. METHOD: The SINGER has been applied in a multicentric validation study. Patients of 17 outpatient rehabilitation centres were included consecutively. In this study patients with stroke or TBI were asked to fill in a questionnaire at 4 points of measurement. Additionally, medical staff were asked to rate the patients' status at admission and discharge. RESULTS AND CONCLUSIONS: SINGER-data could be collected of 429 patients. In sum, results recommend to use the SINGER in outpatient neurorehabilitation, though with some restrictions. In comparison to BI and FIM, the SINGER results show in any case considerably less ceiling effects. The further exclusive use of FIM and, above all, BI cannot be recommended. But for very weak affected patients SINGER is poor sensitive for change and because SINGER is not covering all relevant aspects of rehabilitation a combined clinical use of SINGER and other assessment instruments seems to be a constructive solution.

In the context of developing and testing a procedure for "Outcome-oriented payment for rehabilitation after stroke", we found that the instruments commonly used to measure the outcomes of rehabilitation after stroke (e. g., Barthel-Index or FIM) were not meeting the special requirements of the new payment system. Therefore the "Scores of Independence for Neurologic and Geriatric Rehabilitation" (SINGER) was developed as a new assessment instrument. This instrument is based on the ICF and measures 20 aspects of "independence in activities of daily living". The characteristic feature of the SINGER is, above all, the way all items are graded in 6 steps: the gradation does not refer to the degree of disability but to the kind and amount of help required for the respective activity, i. e.: 0 = totally dependent on professional help; 1 = professional contact help needed; 2 = contact help by (instructed) lay persons sufficient; 3 = preparation or supervision by lay persons still needed; 4 = independent with assistive device or still slow; 5 = independent without assistive device. For experienced personnel in neurologic rehabilitation, these gradations are "intuitively plausible". A manual moreover describes each grade in detail for each item so that the instrument can be used in rehabilitation facilities without extensive training. The SINGER has been tested and validated in a pilot study (n = 100) and in 2 subsequent studies with large case numbers in neurologic rehabilitation (n = 1058 and n = 700 patients after stroke in all categories of severity). Factor analyses showed that the instrument contains 2 dimensions which can be interpreted as "physical activities" and "activities of communication and cognition". Each of these 2 dimensions can be split into 2 sub-dimensions that can be assigned to the tasks of therapeutical professions in care/Occupational Therapy, physiotherapy, logopedics, and neuro- psychology. The test criteria of reliability, sensitivity, convergent validity, floor and ceiling effects as well as sensitivity to change show good to very good results. Particular emphasis can be given to the high degree of interrater reliability and the wide range of possible applications in clinical practice as well as in research. A limitation of the instrument to be taken into account is the fact that the SINGER has not yet been tested and validated in geriatric rehabilitation facilities.

The project aimed at developing and testing a new payment system which provides financial incentives for rehabilitation centers to achieve the best outcomes possible for their patients but does not create additional costs for the insurance funds. The system is conceived as a "quality competition" organized by the centers among themselves with a scientific institute acting as a "referee". Centers with outcomes above average receive a bonus financed by a corresponding malus from the centers below average. In a stepwise process which started in 2001 and was continually accompanied by a scientific institute, we developed the methodological and organizational prerequisites for the new payment system and tested them in two multicentric studies with large case numbers (n=1,058 and n=700, respectively). As a first step, a new assessment instrument (SINGER) was developed and validated in order to measure the outcomes in a reliable, valid, and change-sensitive way. In the second phase, we developed a regression analytic model which predicted the central outcome variable with >84% variance explained. With this model, the different case-mix in the participating centers can be controlled, so that comparisons of outcomes across centers can take place under fair conditions. In the recently completed third phase, we introduced an internet-based programme SINGER-online into which the centers can enter all relevant data. This programme ensures a high quality of all data and makes comparisons of outcomes across all centers possible at any chosen time. The programme contains a special module accessible to the medical services of the health insurance only, which allows sample checks of the data entered by the clinics and helps to ensure that all centers keep to the principles of a fair competition for better quality for their patients. After successful testing of these elements, a functioning model of pay-for-performance in rehabilitation after stroke is now available.
