Background: Digital technologies promise to reduce nurses' workload and increase quality of care. However, considering the plethora of single and review studies published to date, maintaining a comprehensive overview of digital technologies' impact on nursing and effectively utilizing available evidence is challenging.

Objective: This review aims (i) to map published reviews on digital nursing technologies, based on their aims and the specific technologies investigated, to synthesize evidence on how these technologies' uses is associated with (ii) nurses' work-related and organizational factors, professional behavior, and health and work safety and (iii) ethically relevant outcomes for people in need of care.

Design: Preregistered overview of reviews (PROSPERO-ID: CRD42023389751).

Setting(s): We searched for systematic reviews in eight databases, five key journals, and reference lists of included reviews published in English until May 21, 2024.

Methods: We used the AMSTAR 2 checklist to assess the methodological quality of included reviews reporting associations with nursing outcomes. The extracted data were analyzed by their frequency and narratively synthesized.

Results: We identified 213 reviews on digital technologies' uses in the nursing sector. Most of these focused on information and communication technologies. The most frequently reported research objectives encompass technology usage and/or general experiences with it and technology-related consequences for care recipients. Regarding work-related and organizational factors, beneficial impacts were found for the execution of nursing tasks, information management and job control. Depending on the technology type, reviews reported mixed effects for documentation activities, communication/collaboration and mainly negative effects on nurses' workload. Concerning occupational safety and health-related and further nurse outcomes, reviews reported mostly positive effects on nurses' job satisfaction and professional competence. Adverse effects related to mental and physical strain, such as increased frustration, fatigue, and burnout. Regarding ethically relevant outcomes, robotic and telecare technologies had the most reported findings. Most evidence concerned effects on the principles of beneficence/non-maleficence and respect for autonomy.

Conclusions: Digital nursing technologies' legitimacy hinges on their impact on patient outcomes and nurses' work, safety, and health. This review identifies a diverse array of these technologies, with both positive and negative effects. However, due to narrative limitations, meta-analysis was impractical. Future research should quantitatively assess the effects of various digital nursing technologies on work, safety, health, and ethical outcomes.
