Guidelines on the diagnosis, treatment and management of visceral and renal arteries aneurysms: a joint assessment by the Italian Societies of Vascular and Endovascular Surgery (SICVE) and Medical and Interventional Radiology (SIRM).

The objective of these Guidelines is to provide recommendations for the classification, indication, treatment and management of patients suffering from aneurysmal pathology of the visceral and renal arteries. The methodology applied was the GRADE-SIGN version, and followed the instructions of the AGREE quality of reporting checklist. Clinical questions, structured according to the PICO (Population, Intervention, Comparator, Outcome) model, were formulated, and systematic literature reviews were carried out according to them. Selected articles were evaluated through specific methodological checklists. Considered Judgments were compiled for each clinical question in which the characteristics of the body of available evidence were evaluated in order to establish recommendations. Overall, 79 clinical practice recommendations were proposed. Indications for treatment and therapeutic options were discussed for each arterial district, as well as follow-up and medical management, in both candidate patients for conservative therapy and patients who underwent treatment. The recommendations provided by these guidelines simplify and improve decision-making processes and diagnostic-therapeutic pathways of patients with visceral and renal arteries aneurysms. Their widespread use is recommended.

Professional networks and the alignment of individual perceptions about medical innovation.

BACKGROUND: In recent decades, the role of technology in health care organizations has become increasingly relevant because it enhances health care outcomes and the achievement of clinical goals. Extant research demonstrates that the effectiveness of a medical innovation depends largely on health care professionals' perceptions of its usefulness and impact on their activities and practices. We also know that interaction among social actors contributes to the shaping of their judgments and opinions regarding innovation. PURPOSE: This study investigated the role of professionals' social networks and social capital in the formation of similar individual perceptions about a highly innovative robotic surgical system. METHODOLOGY: We collected data from a sample of 50 professionals, including both physicians and nurses, working in three hospital wards belonging to an Italian hospital organization. Using a survey, we gathered data on professionals' demographic characteristics, the adoption and impact of the new technology, and social networks. We tested our hypotheses using a dyadic perspective and logistic regression quadratic assignment procedures. FINDINGS: Our findings document that professionals' perceptions regarding technological change were more likely to be similar when they were connected and exhibited similarity in some social capital characteristics and adoption behavior. PRACTICE IMPLICATIONS: These results have important implications for health care executives and administrators, as well as for health professionals characterized by high degrees of autonomy and for which organizational change can be affected by professional or organizational resistance.

Investigating the Generalizability of Economic Evaluations Conducted in Italy: A Critical Review.

OBJECTIVES: To assess the methodological quality of Italian health economic evaluations and their generalizability or transferability to different settings. METHODS: A literature search was performed on the PubMed search engine to identify trial-based, nonexperimental prospective studies or model-based full economic evaluations carried out in Italy from 1995 to 2013. The studies were randomly assigned to four reviewers who applied a detailed checklist to assess the generalizability and quality of reporting. The review process followed a three-step blinded procedure. The reviewers who carried out the data extraction were blind as to the name of the author(s) of each study. Second, after the first review, articles were reassigned through a second blind randomization to a second reviewer. Finally, any disagreement between the first two reviewers was solved by a senior researcher. RESULTS: One hundred fifty-one economic evaluations eventually met the inclusion criteria. Over time, we observed an increasing transparency in methods and a greater generalizability of results, along with a wider and more representative sample in trials and a larger adoption of transition-Markov models. However, often context-specific economic evaluations are carried out and not enough effort is made to ensure the transferability of their results to other contexts. In recent studies, cost-effectiveness analyses and the use of incremental cost-effectiveness ratio were preferred. CONCLUSIONS: Despite a quite positive temporal trend, generalizability of results still appears as an unsolved question, even if some indication of improvement within Italian studies has been observed.

Quality of care and interhospital collaboration: a study of patient transfers in Italy.

OBJECTIVES: We examine the dynamics of patient-sharing relations within an Italian regional community of 35 hospitals serving approximately 1,300,000 people. We test whether interorganizational relations provide individual patients access to higher quality providers of care. RESEARCH DESIGN AND METHODS: We reconstruct the complete temporal sequence of the 3461 consecutive interhospital patient-sharing events observed between each pair of hospitals in the community during 2005-2008. We distinguish between transfers occurring between and within different medical specialties. We estimate newly derived models for relational event sequences that allow us to control for the most common forms of network-like dependencies that are known to characterize collaborative relations between hospitals. We use 45-day risk-adjusted readmission rate as a proxy for hospital quality. RESULTS: After controls (eg, geographical distance, size, and the existence of prior collaborative relations), we find that patients flow from less to more capable hospitals. We show that this result holds for patient being shared both between as well as within medical specialties. Nonetheless there are strong and persistent other organizational and relational effects driving transfers. CONCLUSIONS: Decentralized patient-sharing decisions taken by the 35 hospitals give rise to a system of collaborative interorganizational arrangements that allow the patient to access hospitals delivering a higher quality of care. This result is relevant for health care policy because it suggests that collaborative relations between hospitals may produce desirable outcomes both for individual patients, and for regional health care systems.

Looking good or doing better? Patterns of decoupling in the implementation of clinical directorates.

BACKGROUND: The interest toward hospital restructuring has risen significantly in recent years. In spite of its potential benefits, often organizational restructuring in health care produces unexpected consequences. Extant research suggests that institutional theory provides a powerful theoretical lens through which hospital restructuring can be described and explained. According to this perspective, the effectiveness of change is strongly related to the extent to which innovative arrangements, tools, or practices are adopted and implemented within hospitals. Whenever these new arrangements require a substantial modification of internal processes and practices, resistance to implementation emerges and organizational change is likely to become neutralized. PURPOSE: This study analyzes how hospital organizations engage in decoupling by adopting but not implementing a new organizational model named clinical directorate. METHODOLOGY: We collected primary data on the diffusion of the clinical directorate model, which was mandated by law in the Italian National Health Service to improve hospital services. We surveyed the adoption and implementation of the clinical directorate model by monitoring the presence of clinical governance tools (measures for the quality improvement of hospital services) within single directorates. In particular, we compared hospitals that adopted the model before (early adopters) or after (later adopters) the mandate was introduced. FINDINGS: Hospitals were engaged in decoupling by adopting the new arrangement but not implementing internal practices and tools for quality improvement. The introduction of the law significantly affected the decoupling, with late-adopter hospitals being less likely to implement the adopted model. PRACTICE IMPLICATIONS: The present research shows that changes in quality improvement processes may vary in relation to policy makers' interventions aimed at boosting the adoption of new hospital arrangements. Hospital administrators need to be aware and identify the institutional changes that might be driven by law to be able to react consistently with expectations of policymakers.

Dynamics of hospital competition: social network analysis in the Italian National Health Service.

BACKGROUND: In the early 1990s, the governments of many countries took the first steps toward introducing market forces into the provision of health care services, with the aim of increasing hospital efficiency and quality of care. Several reforms have been developed to strengthen the role of competition, giving rise to forms of "managed competition." As a result, the environment in which providers operate and perform is increasingly characterized by conditions of competition, rather than of cooperation. PURPOSE: The aim of this study was to analyze the evolution of competitive interdependences among hospitals and the impact of organizational demographics on pair-wise competition. METHODOLOGY: Longitudinal data on competitive interdependences collected within a regional community of hospital organizations in the Italian National Health Service were analyzed. Stochastic actor-based models designed for estimating network dynamics were used to study organizational characteristics influencing patterns of change in competitive interdependences. FINDINGS: The results indicated that interorganizational cooperation is a significant predictor of competitive interdependences, that pair-wise competition among hospitals is primarily local, and that competitive interdependences are more likely to occur between local providers that differed with respect to performance and volume of activity. PRACTICE IMPLICATIONS: Exploring the evolution of competitive interdependences between hospitals is salient for administrators who are interested in increasing their understanding of the whole market. They can better identify direct competitors by paying particular attention to those organizational characteristics that likely predict competitive actions. This approach is also important for policy makers, which may be interested in better targeting hospital restructuring interventions while implementing procompetition reforms.

Dynamic analysis of interhospital collaboration and competition: empirical evidence from an Italian regional health system.

BACKGROUND: Policymakers stimulate competition in universalistic health-care systems while encouraging the formation of service provision networks among hospital organizations. This article addresses a gap in the extant literature by empirically analyzing simultaneous collaboration and competition between hospitals within the Italian National Health Service, where important procompetition reforms have been implemented. PURPOSE: To explore how rising competition between hospitals relates to their propensity to collaborate with other local providers. METHODS: Longitudinal data on interhospital collaboration and competition collected in an Italian region from 2003 to 2007 are analyzed. Social network analysis techniques are applied to study the structure and dynamics of interhospital collaboration. Negative binomial regressions are employed to explore how interhospital competition relates to the collaborative network over time. RESULTS: Competition among providers does not hinder interhospital collaboration. Collaboration is primarily local, with resource complementarity and differentials in the volume of activity and hospital performance explaining the propensity to collaborate. CONCLUSIONS: Formation of collaborative networks among hospitals is not hampered by reforms aimed at fostering market forces. Because procompetition reforms elicit peculiar forms of managed competition in universalistic health systems, studies are needed to clarify whether the positive association between interhospital competition and collaboration can be generalized to other health-care settings.

Understanding hospital performance: the role of network ties and patterns of competition.

BACKGROUND: To improve efficiency and quality, a number of policies have recently been implemented to increase competition and cooperation within the health systems of many countries. We theorize how hospital performance, measured as productivity, is contingent upon network embeddedness, the extent to which a hospital is involved in a network of interconnected interorganizational relationships. PURPOSE: The aim of this study was to explore the effects on hospital productivity resulting from both collaborative network ties and competitive relationships between providers. METHODOLOGY: We used panel data collected between 2003 and 2007 from 35 hospitals in Abruzzo, one of the most populated regions of central Italy. We used secondary data of hospital activities regarding both clinical and administrative aspects. For each year, we examined the intensity of interhospital competition and the unique position each provider has within a larger network of relationships with other hospitals. Other idiosyncratic organizational characteristics were examined as well. FINDINGS: Our results show that hospital productivity is negatively related to the degree of competition that a hospital faces and positively related to the degree with which hospitals establish collaborative relationships. We also found that the negative impact on hospital productivity due to competition was lessened when hospitals were more likely to create cooperative network ties. PRACTICE IMPLICATIONS: Because interhospital collaboration and competition are related to hospital productivity, they should constitute a core element in the strategic planning of a hospital's operation. Health administrators should implement policies that favor collaborative network ties at the regional level and mitigate interorganizational rivalries when establishing collaborative relationships with local competitors.
