Mestrado Integrado Introdução à Medicina I Turma Professor Altamiro Pereira ARTIFICIAL INTELLIGENCE SYSTEMS FOR DIRECT PATIENT CARE IN INTENSIVE CARE UNITS: A SYSTEMATIC REVIEW

2 Professor Altamiro Pereira Turma AI: Definition Medical artificial intelligence is primarily concerned with the construction of AI programs that perform diagnosis and make therapy recommendations. [1] AI in medicine: AI in medicine appeared as an answer to an evolving problem –the escalating amount of information that doctors have to deal with everyday.

3 Professor Altamiro Pereira Turma Introduction AI and ICU Intensive care medicine frequently involves making rapid decisions on the basis of a large and disparate array of information. [2] Since the technology of monitoring astronauts’ vital signs in space was transferred to the bedside in the 1960s, patient monitoring systems have become an indispensable part of critical care. [3] Today, with more biosensors and computational power, these systems can simultaneously gather and display multiple physiological signals, derive clinically important parameters, and generate alerts to clinicians.

4 Professor Altamiro Pereira Turma Introduction Direct Patient Care Since trauma injuries have specific causes, all with established methods of treatment, fatal complications and long-term disabilities can be reduced by making less subjective and more accurate decisions in trauma units. [4] Critically-ill patients need continuous monitoring, which is an impractical, if not impossible, task for the caregivers to carry out solely in the ICU and other critical care settings.

6 Are artificial intelligence systems used and useful when applied to direct patient care in the intensive care unit when compared to the traditional methods? Professor Altamiro Pereira Turma Research question

7 To review the current applications of artificial intelligence for direct patient care in the intensive care unit. Professor Altamiro Pereira Turma Aim

8 Determine if artificial intelligence systems are currently being used in intensive care units for direct patient care; Inspect the benefits and drawbacks of artificial intelligence systems for direct patient care compared to traditional methods of analysis; Professor Altamiro Pereira Turma Specific objectives

9 Expose the use of artificial intelligence systems as decision support mechanisms for direct patient care in intensive care units; Evaluate the acceptance of artificial intelligence systems by the health professionals. Professor Altamiro Pereira Turma Specific objectives

10 4-Interpretation of results and Report Writing. Professor Altamiro Pereira Turma Methods Study design: Systematic review 1- A comprehensive, exhaustive search, in electronic databases, and inclusion of primary studies. 2- Quality assessment of included studies and data extraction (review, by two persons, of the title and the abstract or the article. Same process for the full article. A third opinion may be requested). 3 - Synthesis of study results (SPSS and Review Manager).
