In the Indian construction industry, cost and time overruns are major issues. Project complexity has been cited as a cause of the volatile cost and schedule performance of projects that impact their success. This paper explores significant project complexity determinants and examines the construct construction project complexity. Through a literature review, the study identified twenty-three determinants for project complexity that are specific to the project success parameters of time and cost. The mapping of complex system characteristics, project characteristics, and success parameters as derivable from existing theories was used. The 110 responses from industry experts collected through a survey questionnaire were used to rationalize and categorize these determinants. The data collected is analyzed by an affirmative approach to factor analysis based on maximum likelihood estimation. The goodness-of-fit indices determine the fitness of a model. The results of the analysis establish the validity of the data with sufficient evidence. The scale consists of the organizational, technological, and environmental factors, as well as emergent and goal-oriented information. This can give project managers a better understanding of the key factors that lead to improved decision-making in complex systems.

Contributions by Authors
Both authors contributed equally to the conception of the topic. The corresponding author was responsible for the methodology, literature searches, writing of the draft manuscript, and data collection, analysis, validation, and creation of figures and tables. Both authors have contributed equally to the conceptualization of a theoretical model. Before the manuscript was submitted and published, all authors had read it and approved of its content.
The technology has made health information easier to access, but it could now go even further in helping those with low levels of health literacy. A new development in AI involves a class of tools known as large language models. (For example, Chat GPT). These tools can make health information more personal, understandable, and actionable. This helps patients have a better understanding of their conditions and more control over their care.
Large language models are a technology that has been quickly adopted. These tools have incredible potential once you start using them. Recent research has shown that these technologies can be used to rewrite medical consent information for a reading level of 13 from an educated starting point while keeping all essential information.
AI can also be used to identify relevant information about self-care. This information could then be rewritten in a more accessible way.
This technology can empower individuals by providing them with tailored health information that is based on trusted public sources and adapted to their literacy level. It’s possible also to use an individual’s medical records in order to identify the most pertinent self-care information, which can be rewritten using AI to make it more accessible. It doesn’t have to end there. The large language models are used to create text, but they also fall under a larger category of AI called generative AI. This includes AI, which can create images, audio, and videos. By linking together several AI tools, it may be possible to generate customized content in different formats like audio or animation. All of this could help reduce literacy and numeracy obstacles to self-care. Still, it requires collective action from NHS leaders who work with patients and innovators in setting a vision and a direction for using AI to improve empowerment.
