A Preliminary Study: The Novel AI Voice-Recognition System for Acute Care Hospitals in the United States

Background: The inspiration for the VSC system came from clinical and personal insights over the past 20-30 years. The VSC system was created for patients who experience discomfort and increased fall risk related to their inability to complete simple tasks. Initial Assessment: The objective pilot study is to provide sufficient evidence that the Voice Smart Care (VSC) System could improve quality of care, patient safety, and patient satisfaction. Choice of solution: Two [Institution 1] hospitals located in Southern California have piloted the VSC system in their inpatient smart rooms. The VSC study was a randomized design in order to investigate the efficiency and satisfaction of VSC system which uses both voice and touch controls versus the current standard of care provided by nurses. Implementation: With a simple QR code scan on a smart phone or tablet, the VSC system is activated. The system demonstrates a high level of potential value to the healthcare industry. Patients, families, friends, and nurses can easily control functions from the nursing station and room. Evaluation: The VSC system utilizes existing hospital technologies and is


Introduction
In efforts to improve outcomes and increase quality care, [Institution 1] has begun its journey of utilizing artificial intelligence to enhance healthcare delivery with the Comprehensive Smart Care System. The system will allow patients to use their own smart devices to better access their health care information, control their settings, and grant access to the healthcare professional team after discharge from their inpatient stay. The Comprehensive Smart Care System is a triphasic customized platform which addresses current needs of patients and has the capacity to be built both horizontally and vertically to adopt to the needs and volume of users. The Comprehensive Smart Care System is comprised of three segments, and thus is being implemented in three phases. The first phase of implementation to be completed is the utilization of voiceenabled technology. Voice-enabled technology has been widely used in healthcare [1]; however, none have been implemented in the hospital setting [2]. Our study demonstrates the capabilities of a voice control system prototype, in the United States, by using the Voice Smart Care (VSC) System [3]. Voice recognition control, on a tablet or smartphone, is the ability to detect and interpret human speech and trigger a variety of actions [4]. The objective pilot study is to provide sufficient evidence that the VSC system could improve quality of care, patient safety and patient satisfaction.

Case Presentation
The inspiration for the VSC system came from clinical and personal insights over the past 20-30 years. With the patients' needs in mind and in collaboration with the Internet of Things experts from [institution 2], the VSC system was created. With a simple QR code scan on a smart phone or tablet, the VSC system is activated.
Patients, families, friends, and nurses can easily control functions from the nursing station and room. The VSC system assists with questions and requests such as "turn off the light," "adjust the bed," "call nurse," and "turn on the Television". In an evaluation of the new VSC system, a pilot trial was undertaken to assess the impact of VSC implementation. [Institution 1] conducted a total of 90 case studies, comprising of 75% nurse, 20% patient's family members, and 5% administrative team. From this group of 90 respondents, there were 77% females and 23% males ranging from 21-80 years of age. The questionnaire was written from the patient's family members and staff's perception of their experience with the VSC system. Two [Institution 1] hospitals have piloted the VSC system in their inpatient smart rooms. The VSC study was a case study design in order to investigate the efficiency and satisfaction of VSC system which uses both voice and touch controls. The VSC system is available in English, Spanish, Mandarin, and Cantonese.

Discussion
Our questionnaire follows Technology Acceptance Model (TAM) and consists of two different aspects: a 5-star rating ('1': Strongly Disagree; '2': Disagree;'4': Agree; '5: Strongly Agree) and patient comments. Questionnaire results were further analyzed to categorize Star rating 4 and 5 into "AGREE" and star rating 1 and 2 into "DISAGREE". In the first question, "I am satisfied with the system and would recommend use it in future," 97.7% of respondents reported they are satisfied with the system and would recommend its use in the future. In addition, 98.1% of respondents report they agreed this system's interface was easy to operate and use. Moreover, 97.7 % of individuals find the system useful in simple tasks such as controlling lights, Air Conditioner (AC), Television (TV), and bed adjustment. Furthermore, 98.8% of respondents reported they are satisfied with the VSC system. According to the National Institutes of Health, speech-recognition technology should be adopted and implemented by health care organization as this technology has great impact on the ability of healthcare providers [5,6].
The VSC pilot study has demonstrated improvements in patient satisfaction rates. The system will be gradually implemented hospital wide and to all seven [Institution 1] hospitals to benefit the communities in Southern California. The goal is to make technologies that improve healthcare provider's efficiency and clinical care. In future generations of VSC, the intent is to pair voice recognition apps and machine learning to help diagnose difficult to detect illnesses. A considerable majority of Americans, 95%, now own a cellphone with at least 77% having a smartphone [7]. As this number continues to grow in a mobile technology driven era, healthcare should harness this available resource to better serve their patients. The first aspect of the Comprehensive Smart Care System is the admission segment ( Figure 1). Smart regulations have an important role in setting checks and balances for emerging technologies [8]. Providing linguistically and culturally appropriate services lend to health promotion [9], as primary and tertiary patient education can bring the patient to maximum health with behavioral changes. These advancements in access can mimic patient-clinician relationship [10].
Further studies and revision of the system is required in our future study. [Institution 1] will further expand its study with the implementation of the admission and discharge functions of the Comprehensive Smart Care System. The VSC system could advance improvement in quality of care, patient safety, and patient experience.
