Abstract Background Over the last decades, many high-income countries have successfully implemented assertive outreach mental health services for acute care. Despite evidence that these services entail several benefits for service users, Germany has lagged behind and has been slow in implementing outreach services. In 2018, a new law enabled national mental health care providers to implement team-based crisis intervention services on a regular basis, allowing for different forms of Inpatient Equivalent Home Treatment (IEHT). IEHT is similar to the internationally known Home Treatment or Crisis Resolution Teams. It provides acute psychiatric treatment at the user’s home, similar to inpatient hospital treatment in terms of content, flexibility, and complexity. Methods/design The presented naturalistic, quasi-experimental cohort study will evaluate IEHT in ten hospitals running IEHT services in different German regions. Within a multi-method research approach, it will evaluate stakeholders’ experiences of care, service use, efficacy, costs, treatment processes and implementation processes of IEHT from different perspectives. Quantitative surveys will be used to recruit 360 service users. Subsequently, 180 service users receiving IEHT will be compared with 180 matched statistical ‘twins’ receiving standard inpatient treatment. Assessments will take place at baseline as well as after 6 and 12 months. The primary outcome is the hospital re-admission rate within 12 months. Secondary outcomes include the combined readmission rate, total number of inpatient hospital days, treatment discontinuation rate, quality of life, psycho-social functioning, job integration, recovery, satisfaction with care, shared decision-making, and treatment costs. Additionally, the study will assess the burden of care and satisfaction with care among relatives or informal caregivers. A collaborative research team made up of researchers with and without lived experience of mental distress will conduct qualitative investigations with service users, caregivers and IEHT staff teams to explore critical ingredients and interactions between implementation processes, treatment processes, and outcomes from a stakeholder perspective. Discussion By integrating outcome, process and implementation research as well as different stakeholder perspectives and experiences in one study, this trial captures the various facets of IEHT as a special form of home treatment. Therefore, it allows for an adequate, comprehensive evaluation on different levels of this complex intervention.

Importance: Home treatment (HT) has been associated with fewer inpatient treatment (IT) readmission days but lacks evidence on reducing combined psychiatric hospital service use (IT, HT, day clinic)., Objective: To assess the association of intensive home treatment (IHT) compared with IT regarding readmission rate, social outcomes, and clinical outcomes., Design, Setting, and Participants: This quasi-experimental, nonrandomized trial was conducted from 2020 to 2022 in 10 psychiatric hospitals in Germany. Propensity score (PS) matching was used to compare both treatment models at the 12-month follow-up using standardized instruments and routine hospital data. All patients were screened until the target sample size was reached, based on these criteria: stable residence with privacy for sessions, no child welfare risk, primary diagnosis within International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes F0X to F6X, residence in the catchment area, no commitment order, no acute suicidality or severe aggression requiring hospitalization, capacity to consent, not participating in other interventional studies, sufficient German language skills, no substantial cognitive deficits or intellectual impairment, and no more than 7 days in IHT or IT before recruitment. Statistical analysis was performed from February to November 2023., Intervention: IHT provided daily acute psychiatric treatment at home, while IT was psychiatric inpatient treatment as usual. The mean treatment duration of the index treatment was 37.2 days for IHT and 28.2 days for IT., Main Outcomes and Measures: The inpatient readmission rate was the primary outcome. Secondary outcomes were combined readmission rate, total inpatient days, job integration, quality of life, psychosocial functioning, symptom severity, and recovery., Results: Of 1396 individuals, 200 patients receiving IHT and 200 patients receiving IT were included (264 female [65%]; mean [SD] age, 45.45 [15.83] years [range, 18-88 years]). Baseline sociodemographic and psychometric characteristics did not differ significantly between the groups. At 12-month follow-up, patients in the IHT group had lower inpatient readmission rate (IHT vs IT: 31.12% vs 49.74% IT; mean difference, 18% [95% CI, 9%-28%; P < .001), combined readmission rate (mean difference, 13% [95% CI, 4%-24%; P < .001), and fewer inpatient days (mean difference, 6.82 days; P < .001) than the IT group., Conclusions and Relevance: This nonrandomized clinical trial found that patients receiving IHT had a lower likelihood of utilizing hospital-based psychiatric services and spent fewer inpatient days, suggesting that IHT is a viable alternative to IT., Trial Registration: ClinicalTrials.gov Identifier: NCT04745507.

Background: Inpatient equivalent home treatment (IEHT), implemented in Germany since 2018, is a specific form of home treatment. Between 2021 and 2022, IEHT was compared to inpatient psychiatric treatment in a 12-months follow-up quasi-experimental study with two propensity score matched cohorts in 10 psychiatric centers in Germany. This article reports results on the treatment during the acute episode and focuses on involvement in decision-making, patient satisfaction, and drop-out rates., Methods: A total of 200 service users receiving IEHT were compared with 200 matched statistical "twins" in standard inpatient treatment. Premature termination of treatment as well as reasons for this was assessed using routine data and a questionnaire. In addition, we measured patient satisfaction with care with a specific scale. For the evaluation of patient involvement in treatment decisions, we used the 9-item Shared Decision Making Questionnaire (SDM-Q-9)., Results: Patients were comparable in both groups with regard to sociodemographic and clinical characteristics. Mean length-of-stay was 37 days for IEHT and 28 days for inpatient treatment. In both groups, a similar proportion of participants stopped treatment prematurely. At the end of the acute episode, patient involvement in decision-making (SDM-Q-9) as well as treatment satisfaction scores were significantly higher for IEHT patients compared to inpatients., Conclusions: Compared to inpatient care, IEHT treatment for acute psychiatric episodes was associated with higher treatment satisfaction and more involvement in clinical decisions.

Investigations reporting positive effects of extracorporeal shockwave therapy (ESWT) on nerve regeneration are limited to the rat sciatic nerve model. The effects of ESWT on muscle-in-vein conduits (MVCs) have also not been investigated yet. This study aimed to evaluate the effects of ESWT after repair of the rat median nerve with either autografts (ANGs) or MVCs. In male Lewis rats, a 7 mm segment of the right median nerve was reconstructed either with an ANG or an MVC. For each reconstructive technique, one group of animals received one application of ESWT while the other rats served as controls. The animals were observed for 12 weeks, and nerve regeneration was assessed using computerized gait analysis, the grasping test, electrophysiological evaluations and histological quantification of axons, blood vessels and lymphatic vasculature. Here, we provide for the first time a comprehensive analysis of ESWT effects on nerve regeneration in a rat model of median nerve injury. Furthermore, this study is among the first reporting the quantification of lymphatic vessels following peripheral nerve injury and reconstruction in vivo. While we found no significant direct positive effects of ESWT on peripheral nerve regeneration, results following nerve repair with MVCs were significantly inferior to those after ANG repair.

Computerized gait analysis is a common evaluation method in rat models of hind limb nerve injuries, but its use remains unpublished in models of segmental nerve injury of the forelimb. It was the aim of this work to investigate if computerized gait analysis is a feasible evaluation method in a rat model of segmental median nerve injury and autograft repair. Ten male Lewis rats underwent 7-mm resection of the right median nerve with immediate autograft repair. The left median nerve was resected without repair and served as an internal control. Animals were assessed for 12 weeks after surgery via CatWalk (CW) gait analysis every 2 weeks. Evaluation of motor recovery by means of the grasping test was performed weekly while electrophysiological measurements were performed at the end of the observation period. CW data were correlated with grasping strength at each post-operative time point. CW data were also correlated with electrophysiology using linear regression analysis. Principal component analysis was performed to identify clusters of outcome metrics. Recovery of motor function was observable 4 weeks after surgery, but grasping strength was significantly reduced ( p < 0.01) compared to baseline values until post-operative week 6. In terms of sensory recovery, the pain-related parameter Duty Cycle showed significant ( p < 0.05) recovery starting from post-operative week 8. The Print Area of the right paw was significantly ( p < 0.05) increased compared to the left side starting from post-operative week 10. Various parameters of gait correlated significantly ( p < 0.05) with mean and maximum grasping strength. However, only Stand Index showed a significant correlation with compound muscle action potential (CMAP) amplitude ( p < 0.05). With this work, we prove that computerized gait analysis is a valid and feasible method to evaluate functional recovery after autograft repair of the rat median nerve. We were able to identify parameters such as Print Area, Duty Cycle, and Stand Index, which allow assessment of nerve regeneration. The course of these parameters following nerve resection without repair was also assessed. Additionally, external paw rotation was identified as a valid parameter to evaluate motor reinnervation. In summary, computerized gait analysis is a valuable additional tool to study nerve regeneration in rats with median nerve injury., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Heinzel, Oberhauser, Keibl, Swiadek, Längle, Frick, Kolbenschlag, Prahm, Grillari and Hercher.)
