Time series analysis of outpatient blood collection visits: Fluctuation patterns and nursing staff allocation optimization.

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
Objectives: This study aimed to explore the characteristics of outpatient blood collection center visit fluctuation and nursing workforce allocation based on a time series model, and the application effect was evaluated. Methods: To enhance the efficiency of phlebotomy at the hospital outpatient window and improve patient satisfaction, the First Affiliated Hospital with Nanjing Medical University implemented a time series analysis model in 2024 to optimize nursing staff allocation. The management team was led by a head nurse of the outpatient blood collection department with extensive experience. It included one director of the nursing department, six senior clinical nurses, one informatics expert, and one nursing master's degree holder. Retrospective time-series data from the hospital's smart blood collection system (including hourly blood collection volumes and waiting times) were extracted between January 2020 and December 2023. Time series analysis was used to identify annual, seasonal, monthly, and hourly variation patterns in blood collection volumes. Seasonal decomposition and the Autoregressive Integrated Moving Average Model (ARIMA) were employed to forecast blood collection fluctuations for 2024 and facilitate dynamic scheduling. A comparison was conducted to evaluate differences in blood collection efficiency and patient satisfaction before (January-June 2023) and after (January-June 2024) implementing the dynamic scheduling model based on the time series analysis and forecasting. Results: Visit volumes showed periodicity and slow growth, peaking every second and third quarter of the year and daily at 8:00-9:00 a.m. and 2:00-3:00 p.m. The ARIMA model demonstrated a good fit ( Conclusions: Based on the time series analysis method, it is helpful for nursing managers to accurately allocate human resources and optimize the efficiency of outpatient service resources by mining the special change rule of the outpatient blood collection window and predicting the future fluctuation trend.
