Internet of things in healthcare for patient safety: an empirical study

Abstract

Introduction This study evaluates the impact of an Internet of Things (IoT) intervention in a hospital unit and provides empirical evidence on the effects of smart technologies on patient safety (patient falls and hand hygiene compliance rate) and staff experiences. Method We have conducted a post-intervention analysis of hand hygiene (HH) compliance rate, and a pre-and post-intervention interrupted time-series (ITS) analysis of the patient falls rates. Lastly, we investigated staff experiences by conducting semi-structured open-ended interviews based on Roger’s Diffusion of Innovation Theory. Results The results showed that (i) there was no statistically significant change in the mean patient fall rates. ITS analysis revealed non-significant incremental changes in mean patient falls (− 0.14 falls/quarter/1000 patient-days). (ii) HH compliance rates were observed to increase in the first year then decrease in the second year for all staff types and room types. (iii) qualitative interviews with the nurses reported improvement in direct patient care time, and a reduced number of patient falls. Conclusion This study provides empirical evidence of some positive changes in the outcome variables of interest and the interviews with the staff of that unit reported similar results as well. Notably, our observations identified behavioral and environmental issues as being particularly important for ensuring success during an IoT innovation implementation within a hospital setting.

Modeling and implementation of a low-cost IoT-smart weather monitoring station and air quality assessment based on fuzzy inference model and MQTT protocol

“…The IoT transforms physical objects into network devices that can share their resources with other participants or even other objects (Brandão et al 2021 ). The IoT has been operationalized extensively in many areas, such as healthcare (Yesmin et al 2022 ), farming (Patel et al 2022 ; Xu et al 2022 ), home automation (Almusaylim and Zaman 2019 ), smart cities (Bellini et al 2022 ), and weather monitoring systems. Accurate weather information also benefits various fields, including electricity generation, agriculture, and transportation.…”

Harnessing public health with “metaverse” technology

“…(4) There is still a significant amount of non-standard diagnosis and treatment, with characteristics of a handicraft workshop, because there is no real-time quality control in all situations. (5) The circumstances. It is the limits of Internet technology that prevent contact between Cloud Experts and Terminal Doctors engaged in graded diagnosis and therapy from constantly being facilitated.…”

“…It is the limits of Internet technology that prevent contact between Cloud Experts and Terminal Doctors engaged in graded diagnosis and therapy from constantly being facilitated. Because of this, MIoT-based digital platforms need to keep getting better, especially in the areas of communication and interaction between humans and computers, as well as the integration and linking of the virtual and real worlds, Ultimately, to realize “complex problems are simplified; simple problems are digitized; digital problems are programmed; and program problems are systematized” ( 5 ).…”

A saúde digital e sua interface com a segurança do paciente e o cuidado perioperatório

“…Sua utilização cresce exponencialmente, acelerada pela pandemia de COVID-19, que impôs a incorporação de novas modalidades no cuidado ao paciente. A utilização de sistemas informatizados, aplicativos móveis e internet das coisas permite melhoria do fluxo assistencial e da segurança do paciente, integração de equipes, apoio à decisão clínica, vigilância, promoção da saúde e aprimoramento da gestão 2,3 .…”
