BACKGROUND A novel medical device has been developed to address an unmet need in standardising and facilitating heart rate recording during neonatal resuscitation. In a time critical emergency resuscitation, where failure can mean death of an infant, it is vital that clinicians are provided with information in a timely, precise and clear manner to capacitate appropriate decision making. This new technology provides a hands free, wireless heart rate monitoring solution that easily fits the clinical pathway and procedure for neonatal resuscutation. To understand the requirements of the interface design for this new device, a human factors approach was implemented. This combined a traditional user-centred design approach with an Applied Cognititive Task Analysis (ACTA) to understand the tasks involved, the cognitive requirements and the potential for error during a neonatal resusciation scenario. OBJECTIVE 1. To understand the cognitive requirements of clinicians for a novel medical device to facilitate neonatal resuscitation; 2. To apply a human factors approach and a traditional user-centred design approach to provide a device interface specification. METHODS Fourteen clinical staff were involved in producing the final design requirements. Two paediatric doctors supported the development of a visual representation of the activities associated with neonatal resucitation. This was used to develop a scenario based workshop. Two workshops were carried out in parallel and involved three paediatric doctors, three neonatal nurses, two advance neonatal practitioners and four midwives. Both groups came together at the end to reflect on the findings which emerged during the separate sessions. RESULTS The outputs of this study have provided a comprehensive description of information requirements during neonatal resuscitation, and enabled product developers to understand the core and preferred requirements of the user interface design for the device. The study raised three key areas for the designers to consider, which had not previously been highlighted. These related to interface layout and information priority, size and portability of the device and auditory feedback. CONCLUSIONS This study demonstrates the value of the ACTA approach to inform the development of resuscitation devices, and more generally for medical device development.

This new technology provides a hands-free, wireless heart rate monitoring solution that easily fits the clinical pathway and procedure for neonatal resuscitation. Objective This study aimed to understand the requirements of the interface design for a new device by using a human factors approach. This approach combined a traditional user-centered design approach with an applied cognitive task analysis to understand the tasks involved, the cognitive requirements, and the potential for error during a neonatal resuscitation scenario. Methods Fourteen clinical staff were involved in producing the final design requirements.

Both groups came together at the end to reflect on the findings from the separate sessions. Results The outputs of this study have provided a comprehensive description of information requirements during neonatal resuscitation and enabled product developers to understand the preferred requirements of the user interface design for the device. The study raised three key areas for the designers to consider, which had not previously been highlighted: (1) interface layout and information priority, as heart rate should be central and occupy two-thirds of the screen; (2) size and portability, to enable positioning of the product local to the baby’s head and allow visibility from all angles; and (3) auditory feedback, to support visual information on heart rate rhythm and reliability of the trace with an early alert for intervention while avoiding parental distress. Conclusions This study demonstrates the application of human factors and the applied cognitive task analysis method, which identified previously unidentified user requirements. This methodology provides a useful approach to aid development of the clinical interface for medical devices.

And Behavior

Typically when an error occurs in healthcare, the care provider is considered the cause. Because that person committed the act that lead to the adverse outcome efforts to address the error are directed to that person. Indeed, human factors practitioners have developed remedial training and their medical device design activities have emphasized user interface design. This paper presents the case for expanding that focus based on the realization that the act of committing an error is a behavior and behavior reflects the interaction of the person and factors in the environment. The counterintuitive findings that more errors occur in prescribing medications with computer order entry than with handwritten script are discussed in terms of this approach.

Picking System

Purpose In order-picking activities, the performance of the system can be influenced by different variables such as the order to be fulfilled, the distance to be covered or the experience of operators. Usually, this kind of activity is performed by operators rather than machines to assure flexibility. Consequently, their fatigue accumulation can decrease the performance of the overall system. The purpose of this paper is to define the kind of device to be used in an order-picking context, to obtain data which can be utilized for the evaluation of the level of fatigue and to improve the performance of the picking system. Design/methodology/approach The paper presents a comparison between existing fatigue methods which can be applied in a picking context. In addition, an analysis of the physiological literature for the evaluation of a new device for the monitoring of fatigue level is carried on and its practical use is shown. Findings The proposed research identifies in the heart rate monitor the device that, thanks to its advantages, can be the best one to be used in an industrial context for monitoring the physical fatigue of operators. Originality/value This study considers the importance of human factors in picking activities such as physical fatigue of operators and the need to have validated tools to monitor and to define the level of fatigue accumulation in each activity of different rate and duration.

Human error is often cited as the most common cause of medical device mishaps. The role that a poorly designed user interface plays in precipitating these errors is infrequently acknowledged. This study focused on the Abbott PCA Infuser, a commonly used medical device. A review of FDA incident reports showed that human error is responsible for 68% of fatalities and serious injuries associated with the Abbott PCA. We sought to demonstrate that the incidence of human error can be significantly reduced through a human factors approach to interface design. A redesigned interface was developed, then empirically evaluated with a group of recovery room nurses, experienced PCA users. The results of the evaluations showed a 55% reduction in errors, an 18% improvement in performance time, a 14% reduction in mental workload, and a strong preference by nurses for the redesigned interface. These findings demonstrate that quantifiable improvements in equipment safety and efficiency can be achieved by adopting a human factors approach to interface design.

Tobacco smoke is enormously harmful to human health, there’s no safe way to smoke. The primary objective of this study is to analyze the role of tobacco smoke compounds and their ability to damage the cardiovascular system and, in particular, to interfere with blood pressure (Brachial and radial pressure), heart rate and partly on the percentage blood Oxygen saturation. A new device has been manufactured which is unique for measuring the level of smoke, to obtained privies readings, the device had fixed to the first reference level آ and starting up from it. The effect of smoking has been studied on (26) male passive (26) active smoker volunteer, (14) female passive and (14) female active smoker participants. The results has been showed that the blood pressure and heart rate has been increased with increasing the number of cigarettes in both genders for passive and active smokers. However, this effect for male was more pronounced comparing with females for passive and active smokers. In the case of oxygen saturation concentration percentage, for males the change of oxygen concentration percentage was not stable. In other words, it was fluctuated with the number of cigarettes. But for females the oxygen concentration was decreased but not too much. This means that this effect was not pronounced. this study found آ that the most pronounced effect has been shown by male’s comparison to females for both passive and active smokers. As well as in nonsmoker’s males, the relation between heart rate and smoke level is inversely proportional. While in male and female smokers and female nonsmokers the relation is proportional. In all cases the relation between the smoke level and time of smoking is inversely proportional. Finally males& females are affected differently by tobacco use; the sensitivities to smoke for males are higher than in females for passive and active smokers in both brachial and radial blood pressure measurement.

The initial bedside care of premature babies with an intact cord has been shown to reduce mortality; there is evidence that resuscitation of term babies with an intact cord may also improve outcomes. This process has been facilitated by the development of bedside resuscitation surfaces. These new devices are unaffordable, however, in most of sub-Saharan Africa, where 42% of the world’s 2.4 million annual newborn deaths occur. This paper describes the rationale and design of BabySaver, an innovative low-cost mobile resuscitation unit, which was developed iteratively over five years in a collaboration between the Sanyu Africa Research Institute (SAfRI) in Uganda and the University of Liverpool in the UK. The final BabySaver design comprises two compartments; a tray to provide a firm resuscitation surface, and a base to store resuscitation equipment. The design was formed while considering contextual factors, using the views of individual women from the community served by the local hospitals, medical staff, and skilled birth attendants in both Uganda and the UK.

Voice Response

The purpose of this paper is to present a case for the development of a user interface design guideline or standard for interactive voice response applications, to be widely disseminated throughout business and industry. A number of sample problems are cited, based on the author's consulting experience in this area, which serve to demonstrate that many of the problems encountered in IVR application development, particularly in scripting/dialogue design and use of automated speech recognition as a front-end, are not only solvable, but easily avoidable, given the current human factors knowledge base. The paper also discusses the Specification Document developed by the Voice Messaging User Interface Forum (1990, April), and the reasons why it cannot be applied, as written, to the user interface design of more complex IVR applications. Finally, the author proposes an approach to developing the proposed guideline/standard.
