The effects of improving hospital physicians working conditions on patient care: a prospective, controlled intervention study

Background: Physicians, particularly in hospitals, suffer from adverse working conditions. There is a close link between physicians' psychosocial work environment and the quality of the work they deliver. Our study aimed to explore whether a participatory work-design intervention involving hospital physicians is effective in improving working conditions and quality of patient care. Methods: A prospective, controlled intervention study was conducted in two surgical and two internal departments. Participants were 57 hospital physicians and 1581 inpatients. The intervention was a structured, participatory intervention based on continuous group meetings. Physicians actively analyzed problematic working conditions, developed solutions, and initiated their implementation. Physicians' working conditions and patients' perceived quality of care were outcome criteria. These variables were assessed by standardized questionnaires. Additional data on implementation status were gathered through interviews. Results: Over the course of ten months, several work-related problems were identified, categorized, and ten solutions were implemented. Post-intervention, physicians in the intervention departments reported substantially less conflicting demands and enhanced quality of cooperation with patients' relatives, compared to control group physicians. Moreover, positive changes in enhanced colleague support could be attributed to the intervention. Regarding patient reports of care quality of care, patient ratings of physicians organization of care improved for physicians in the intervention group. Five interviews with involved physicians confirm the plausibility of obtained results, provide information on implementation status and sustainability of the solutions, and highlight process-related factors for re-design interventions to improve hospital physicians work. Conclusions: This study demonstrates that participatory work design for hospital physicians is a promising intervention for improving working conditions and promoting patient quality of care

Triple-cation perovskite solar cells fabricated by hybrid PVD/blade coating process using green solvents

The scalability of highly efficient organic-inorganic perovskite solar cells (PSCs) is one of the remaining challenges of solar module manufacturing. Various scalable methods have been explored to strive for uniform perovskite films of high crystal quality on large-area substrates. However, each of these methods have individual drawbacks, limiting the successful commercialization of perovskite photovoltaics. Here, we report a fully scalable hybrid process, which combines vapor- and solution-based techniques to deposit high quality uniform perovskite films on large-area substrates. This two-step process does not use toxic solvents, and it further allows facile implementation of passivation strategies and additives. We fabricated PSCs based on this process and used blade coating to deposit both charge transporting layers (SnO2 and Spiro-OMeTAD) without hazardous solvents in ambient air. The fabricated PSCs have yielded open-circuit voltage up to 1.16 V and power conversion efficiency of 18.7 % with good uniformity on 5 cm x 5 cm substrates

Photonic Sintering of Oxide Ceramic Films: Effect of Colored Fe_xO_y Nanoparticle Pigments

Alumina and zirconia thin films modified with colored nano-FexOy pigments were sintered by the flash-lamp-annealing method. We selected a nano α-Al2O3 and micron α-Al2O3 bimodal mixture as the base precursor material, and we doped it with 5 vol% of FexOy red/brown/black/yellow pigments. The coatings were deposited from nanoparticle dispersions both on glass and on flexible metal foil. The characteristics of the thin films obtained with the use of various additives were compared, including the surface morphologies, optical properties, crystallinities, and structures. Flash lamp annealing was applied with the maximum total energy density of 130 J/cm2 and an overall annealing time of 7 s. Based on the simulated temperature profiles and electron-microscopy results, a maximum annealing temperature of 1850 °C was reached for the red Al2O3: Fe2O3 ceramic film. The results show that red α-Fe2O3 pigments allow for the achievement of maximum layer absorption, which is effective for flash lamp sintering. It was also possible to use the selected red α-Fe2O3 particles for the flash-lamp-assisted sintering of ZrO2 on a 30 µm-thin flexible stainless-steel substrate
