[Rehabilitation Recommendations According to § 31 SGB XI: Empiricism, Discussion and Health Policy Implications]. / Reha-Empfehlungen nach § 31 SGB XI: Empirie, Diskussion und gesundheitspolitische Implikationen.

BACKGROUND: The principle of "rehabilitation before care" is a principle of social law. The recommendation of the Medical Service (MD) as part of the assessment (§ 31 SGB XI) plays an important role in rehabilitation recommendations. In around 3% of its assessments, the MD recommends implementation of rehabilitation. Only every fourth to fifth recommendation is actually carried out. The aim of the study was to find out if rehabilitation recommendations are utilized and exploited. MATERIALS AND METHODS: This study aimed to examine the perspective of insured persons whose recommended rehabilitation was actually carried out. After evaluating 586,228 routine data records with care assessments by the MD, 1,972 survey questionnaires were sent out in March 2023, and 1,116 analyzable questionnaires were included in the data analysis. In seven questions, the respondents were asked to retrospectively assess the overall success and satisfaction with rehabilitation procedures carried out. RESULTS: The evaluation of the results showed that 87% of the study participants would be ready to undergo repeat rehabilitation. The assessment of the success of rehabilitation in terms of remaining at home for a longer period of time also carried weight. On the other hand, only around 10% of rehabilitation was carried out on an outpatient basis. CONCLUSIONS: One previously assumed reason for the low rate of patients taking advantage of recommended rehabilitation was that those in need of care had already received rehabilitation in the previous year. In this study focussing on whether recommended rehabilitation is taken advantage of, this assumption was found not to be correct. The question needs to be raised whether the strong focus in Germany on inpatient rehabilitation is up-to-date, both medically and with regard to the preferences of those entitled to rehabilitation. In contrast to inpatient rehabilitation, individual, outpatient and, if necessary, mobile rehabilitation offers might be more suitable, and these would also take into consideration issues of individual mobility and patient autonomy. The offer of different modes of rehabilitation also enables meeting the wish of those patients who prefer to have rehabilitation carried out in a home environment.

Deep-UV-enhanced supercontinuum generated in a tapered gas-filled photonic crystal fiber.

We present the use of a linearly down-tapered gas-filled hollow-core photonic crystal fiber in a single stage, pumped with pulses from a compact infrared (IR) laser source, to generate a supercontinuum (SC) carrying significant spectral power in the deep ultraviolet (UV) [200-300 nm]. The generated SC extends from the near IR down to ∼213nm with 0.58 mW/nm and down to ∼220nm with 0.83 mW/nm in the deep UV.

Dispersion tuning in sub-micron tapers for third-harmonic and photon triplet generation.

Precise control of the dispersion landscape is of crucial importance if optical fibers are to be successfully used for the generation of three-photon states of light-the inverse of third-harmonic generation (THG). Here we report gas-tuning of intermodal phase-matched THG in sub-micron-diameter tapered optical fiber. By adjusting the pressure of the surrounding argon gas up to 50 bars, intermodally phase-matched third-harmonic light can be generated for pump wavelengths within a 15 nm range around 1.38 µm. We also measure the infrared fluorescence generated in the fiber when pumped in the visible and estimate that the accidental coincidence rate in this signal is lower than the predicted detection rate of photon triplets.

Single-shot reconstruction of spectral amplitude and phase in a fiber ring cavity at a 80 MHz repetition rate.

Femtosecond pulses circulating in a synchronously driven fiber ring cavity have complex amplitude and phase profiles that can change completely from one round-trip to the next. We use a recently developed technique, combining dispersive Fourier transformation) with spectral interferometry, to reconstruct the spectral amplitude and phase at each round-trip and, thereby, follow in detail the pulse reorganization that occurs. We focus on two different regimes: a period-two regime in which the pulse alternates between two distinct states and a highly complex regime. We characterize the spectral amplitude and phase of the pulses in both regimes at a repetition rate of 75.6 MHz and find good agreement with modeling of the system based on numerical solutions of the generalized nonlinear Schrödinger equation with feedback.
