To assess the level of alarm fatigue among intensive care unit (ICU), cardiac care unit (CCU) and emergency room (ER) nurses, identify associated demographic and occupational factors, determine the most frequent sources of alarms and evaluate nurses’ psychological reactions to alarms.

A cross-sectional, descriptive–analytical study.

ICUs, CCUs and ERs of six public teaching hospitals affiliated with Tehran and Kashan Universities of Medical Sciences in Iran.

Using a multistage stratified random sampling method, 285 nurses were approached, of whom 260 completed and returned the questionnaires (response rate: 91%). Participants were registered nurses with at least a bachelor’s degree or higher and 3 months of experience in ICUs, CCUs or ERs.

The primary outcome was the level of alarm fatigue measured using the validated Nurses’ Alarm Fatigue Questionnaire. Secondary outcomes included factors associated with alarm fatigue and nurses’ reported psychological responses to frequent alarms.

The mean score of alarm fatigue was 26.4±7.9, indicating a moderate level. After adjusting for confounders and hospital-level clustering using multivariable mixed-effects regression, higher monthly income was significantly associated with lower alarm fatigue (β=–0.15, p=0.03), and nurses working rotational shifts reported significantly higher fatigue compared with those with fixed shifts (β=0.18, p=0.02). Other demographic and occupational factors were not significant. Reported psychological reactions to alarms included indifference (14%), irritability (18%) and anxiety/stress (15%).

ICU, CCU and ER nurses experience a moderate level of alarm fatigue, with income and shift type as independent associated factors. The association between income and alarm fatigue may reflect the role of financial stress as an additional job demand that compounds the burden of frequent alarms, particularly in contexts where low base salaries lead nurses to rely on overtime and multiple shifts. These findings underscore the need for targeted managerial and educational interventions, including shift schedule optimisation and attention to workload-related stressors, alongside alarm prioritisation strategies. Due to the cross-sectional design, causal inferences cannot be drawn.

Knee osteoarthritis (KOA) is a prevalent degenerative joint disorder, often accompanied by comorbidities like type 2 diabetes mellitus (T2DM). These conditions have a significant impact on patients’ sleep quality and metabolic health. Current treatments for KOA primarily focus on symptom management, while innovative approaches targeting interconnected health outcomes remain underexplored. The lumbar knee recovery device, a non-invasive device patented in Iran, offers potential benefits by enhancing lumbar-knee synchronisation, improving blood circulation and optimising cellular metabolism. This randomised controlled trial (RCT) aims to evaluate the device’s effectiveness in improving sleep quality and regulating blood glucose levels in diabetic patients with KOA.

This RCT aims to evaluate the impact of using the lumbar knee recovery device (Kamarasa) on sleep quality, blood glucose levels, HbA1c (blood glucose control level over the past 90 days) and body mass index (BMI) in patients with T2DM and grade 1–3 KOA. The study will be conducted at the Orthopedic Clinic of Imam Khomeini Hospital, Tehran, and the Health and Wellness Clinic. Eligible participants will be randomly allocated into two groups: the intervention group (receiving 10 supervised sessions using the Recovery device over 3 months) and the control group (receiving standard KOA and diabetes care). A total of 37 participants will be included in each group. The primary outcome, sleep quality, will be assessed using the Pittsburgh Sleep Quality Index at baseline and 3 months post intervention. Secondary outcomes will include random blood glucose levels, which will be measured at 10 intervals during the study; BMI, measured at the start and end of the study and HbA1c, assessed at both baseline and post intervention. The Western Ontario and McMaster Universities Arthritis Index will be used to assess pain, stiffness and physical function, also at both baseline and 3 months. Appropriate statistical tests, including two-sample t-tests, ² tests, analysis of covariance or linear regression, will be performed based on the type of variables using SPSS V.23. Additionally, standardised intervention effect sizes will be calculated for each outcome.

Ethical approval for this study was obtained from the Research Ethics Committee of the School of Nursing and Midwifery at Tehran University of Medical Sciences with reference number (IR.TUMS.FNM.REC.1403.145). Additionally, the study protocol was registered with the IRCT under the identifier IRCT20191027045257N7 on 24 November 2024.

The Scholarship of Teaching and Learning (SoTL) is emphasised more than ever in today’s higher education institutions. SoTL is crucial in enhancing nursing education and improving student learning outcomes, thereby preparing competent nurses to deliver high-quality healthcare. Despite its importance, the dimensions and defining characteristics of SoTL have not been adequately explored. This scoping review aims to clarify the concept of SoTL in nursing education, identify its key features and address existing knowledge gaps in this field.

The study adopts Arksey and O’Malley’s established scoping review methodology, as defined by the Joanna Briggs Institute (JBI). The research process is guided by five distinct phases: the initial formulation of research questions, identification of relevant studies, selection of studies, data extraction and compilation and, finally, synthesis and reporting of results.

The inclusion criteria will be based on the Population, Concept and Context framework. A comprehensive search will be conducted across PubMed, Embase, Scopus, ProQuest, Web of Science, ERIC and grey literature sources, with no time limitations and ongoing updates until the study concludes.

To ensure a comprehensive review, reference lists and citations of selected studies will also be examined for additional relevant sources. Duplicate studies and studies published in languages other than Persian or English will be excluded. Two independent reviewers will select studies based on eligibility criteria and screen the title, abstract and full text. Data extraction will be conducted using the standard JBI form. A directed content analysis will be undertaken to identify and clarify key concepts in the texts.

The Research Ethics Committee of Iran University of Medical Sciences has approved this study. The results will be published in scientific publications and presented at relevant conferences.

The protocol was registered on the Open Science Framework (OSF; https://doi.org/10.17605/OSF.IO/VN5GD).
