Perceived Nursing Interruptions During Medication Administration: Development and Validation of a Questionnaire Among Chinese Nurses.
Article in Journal of nursing management, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNursing interruptions during medication administration occur frequently, often leading to medication errors and workflow delays that threaten patient safety and reduce nurses' work efficiency. Current research has relied mainly on observation or interviews, which are labor-intensive, time-consuming, and prone to substantial variability. Practical, standardized instruments are needed to assess nursing interruptions during medication administration (NIMA).
methodsThis cross-sectional descriptive study developed and validated the questionnaire for measuring nursing interruptions during medication administration (Q-NIMA) through a multistep, theory-driven process based on the Systems Engineering Initiative for Patient Safety model. Items were generated from literature and expert input, refined by two Delphi rounds with 12 experts, and piloted with 30 nurses. Item analysis was conducted for comprehensive evaluation, and validity evidence was gathered based on test content, internal structure, and relations to other variables. The sample was split for exploratory factor analysis (EFA) using FACTOR software (based on polychoric correlations and ULS extraction) and confirmatory factor analysis (CFA) using AMOS. Reliability was assessed using internal consistency (Cronbach's α and ORION coefficients) and stability (test-retest reliability).
resultsWe selected 478 nurses from a tertiary hospital in Hunan Province from July to August 2025. The final questionnaire comprised 25 items across five dimensions. Item analysis indicated that the questionnaire had strong discriminant validity. The content validity indexes were 0.944 at scale level and 0.833-1.000 at item level. EFA extracted five factors explaining 74.25% of the total variance. CFA demonstrated good model fit (X
conclusionThe Q-NIMA demonstrates robust psychometric properties, including high reliability, validity, and stability. Furthermore, it serves as a valuable tool to evaluate how nurses perceive nursing interruptions during medication administration. By aligning items with medication tasks and work-system elements, the Q-NIMA moves beyond event counting to support risk profiling and targeted improvement of medication administration.
