Correlation between Diagnosis-related Group Weights and Nursing Time in the Cardiology Department: A Cross-sectional Study
ABSTRACT
Background:
Nursing workload measurement is beneficial for effectively avoiding the waste of nursing labor costs due to unreasonable staffing.
Objective:
To explore the value of diagnosis-related group (DRG) weights and related indexes in the nursing management of the cardiology department.
Methods:
A total of 103 hospitalized patients from April 2023 to April 2024 in the ward of the cardiology department were selected using a random number table.
Results:
Significant logarithmic value differences were observed in direct nursing time, indirect nursing time, and total nursing time among patients with/without complications (t = 2.230, t = 2.449, t = 2.445, all P < 0.05), with/without surgery (t = 5.324, t = 4.584, t = 5.199, all P < 0.05), different nursing levels on the first day of admission (F = 45.421, F = 25.435, F = 35.495, all P < 0.05), and different DRG weights (F = 32.455, F = 28.581, F = 29.435, all P < 0.05). Additionally, DRG weights were positively correlated with Ln (direct nursing time), Ln (indirect nursing time), and Ln (total nursing time) (r = 0.480, r = 0.394, r = 0.448, all P < 0.01). Moreover, age was positively correlated with the 3 nursing times (r = 0.235, r = 0.192, r = 0.235, all P < 0.01); activities of daily living (ADL) on admission was negatively correlated with the 3 nursing times (r = -0.316, r = -0.252, r = -0.301, all P < 0.01); and nursing level on the first day of admission was positively correlated with the 3 nursing time (r = 0.333, r = 0.332, r = 0.352, all P < 0.01). Furthermore, the multivariate analysis found that nursing levels on the first day of admission, complications or comorbidities, DRG weights, and ADL on admission were the influencing factors of the nursing time of patients (R2 = 0.328, F = 69.58, P < 0.05).
Conclusions:
The correlation between DRG weights and nursing workload in the cardiology department indicates that nursing workload can be predicted using the DRG weights-based multivariate regression equation, thereby building a bridge between DRG and nursing management while laying a foundation for further in-depth study.
