Management Barriers to Inter-Organizational Collaboration in Preoperative Treatment of Patients with Hip or Knee Osteoarthritis.

Inter-organizational collaboration among healthcare institutions is widely recognized to improve healthcare services. Because there is a research gap in examining the management barriers to inter-organizational collaboration in countries with less efficient healthcare systems and the reasons for non-implementation of innovations, the aim of this study was to identify key management barriers to inter-organizational collaboration in the preoperative treatment of patients with hip or knee osteoarthritis in Slovenia using a mixed-methods approach with key stakeholders. A cross-sectional study was conducted using multiple methods. An online survey (n = 135) and a multilevel qualitative approach were used, interviewing patients (n = 21), healthcare professionals, and other stakeholders (n = 42). The overall assessment of barriers affecting the integrated approach at the macro, meso, and micro levels revealed that macro-level factors were statistically significantly perceived as the major barriers, while micro-level factors were the minor barriers. There was no significant difference between public and private sector respondents in the barriers at the three levels. However, there were significant differences in the perceptions of different professional groups at the micro and meso levels, but not at the macro level. The analysis of the in-depth interviews confirmed the importance of macro-level barriers. A culture of noncooperation combined with "managerial indecision" prevails in the Slovenian healthcare system due to weak management support for inter-organizational collaboration, with managers and other key stakeholders failing to make urgent decisions due to a lack of autonomy. Interviewees commonly noted that one of the major barriers to inter-organizational collaboration was a lack of resources and staff, particularly of primary care physicians and nurses. In the preoperative treatment of patients with hip or knee osteoarthritis, the culture of non-collaboration and executive indecision are the major macro-level barriers to inter-organizational collaboration in Slovenia.

Association Between Preventive Behaviour and Anxiety at the Start of the COVID-19 Pandemic in Slovenia.

INTRODUCTION: The first large outbreak of SARS-CoV-2 in Europe occurred in Northern Italy in February 2020. The relatively fast spread of the infection to Slovenia was expected, and preventive measures for its suppression were widely discussed. METHODS: An online questionnaire was designed to evaluate adherence to preventive measures and the extent to which the taking of preventive measures was associated with people's anxiety level, psychological burden, their perceived vulnerability to disease, germ aversion and a number of demographic characteristics in the early stage of Covid-19 spread. The survey was active for 24 hours (13-14 March 2020). There were 12,307 responses and 7,764 questionnaires were completed in full. RESULTS: Higher preventive behaviour was found in individuals who experienced greater psychological distress, were more anxious, and expressed greater perceived infectability and germ aversion. Greater compliance with preventive behaviour was found among women, those sharing a household with people aged over 65, the elderly and those who knew somebody who had been infected. These groups also showed higher anxiety levels, which appeared to be significantly increased in general as a result of the specific situation. Quarantine was evaluated as the most efficient preventive measure, and was respected relatively strictly even before it became an officially announced protective measure. CONCLUSION: This research reveals a strong association between preventive behaviour and anxiety. Anxiety, together with social distancing, may affect physical and psychological health in the population in the long term. Other aspects of public health might therefore be influenced by the measures currently being enforced to prevent the spread of SARS-CoV-2.

The optimal combination of cartilage source and apparatus for long-term in vitro chondrocyte viability analysis.

Most studies of long-term chondrocytes survival were for tissue banks. They showed a gradual reduction in the viable chondrocytes percentage as a function of time and ambient temperature, but the samples were harvested under optimal conditions. The aim of our study was to determine the most reliable combination of cartilage source and assay for the in vitro postmortem chondrocyte viability analysis in the conditions that imitate a dead body. Osteochondral cylinders were procured from femoral condyles and talar trochleas of three male donors and stored in the cell culture media at 4 ± 2°C and 23 ± 2°C. The samples were analyzed by a cell viability analyzer and a confocal laser scanning microscope (CLSM) initially 24-36 h after death and then in 4-week intervals. The results reconfirmed the significant influence of time (p = 0.0002), but not of the temperature (p = 0.237). The largest reproducibility was presented for the knee joint and the CLSM.

Fibrin gel improved the spatial uniformity and phenotype of human chondrocytes seeded on collagen scaffolds.

A scaffold made of equine collagen type I based material has been assessed for its use in the preparation of tissue-engineered cartilage implants with human articular chondrocytes. Improvements of cell-seeding efficiency and specific gene expression were studied by combining solid scaffold with fibrin glue or human blood plasma. Following 3 weeks of static culture, mRNA expression levels of collagen type I, collagen type II, aggrecan and versican were analyzed by real-time quantitative PCR and compared to those in native cartilage and monolayer cell cultures. Constructs prepared with fibrin glue or plasma showed higher cell seeding efficiencies than those prepared without gel. Chondrocytes seeded directly onto a collagen scaffold appeared fibroblastic in shape while those encapsulated in fibrin gel were spherical. The presence of fibrin glue positively influences on mRNA levels of collagen type II and aggrecan, while blood plasma enhanced only the level of collagen type II expression. Levels of collagen type I and versican decreased in presence of fibrin glue. In orthopaedics, the combination of solid collagen fleece with fibrin gel for implant preparation is seen to be preferred over solid material or even cells in a suspension, since fibrin gel improves seeding capacity of the scaffold, supports equal distribution of cells and stimulates higher chondrogenic phenotype expression.
