Objective:
To systematically review the factors influencing thirst in ICU patients, providing a reference for effective management of thirst in ICU patients and the formulation of intervention measures.
Methods:
A total of 12 electronic databases were searched from inception to July 2023. The synthesis method of JBI mixed methods research systematic review was used. The quantitative studies were analyzed by Stata17.0 and RevMan 5.3 software, and the qualitative studies by meta-aggregation.
Results:
A total of 13 studies were included, including 2 qualitative studies and 11 quantitative studies. The quantitative study was carried out by meta-aggregation, extracting seven categories to form two synthesized findings. Quantitative meta-analysis revealed that 11 factors, including marital status, whether to use mechanical ventilation for the first time, air leakage, mechanical ventilation mode, simplified acute physiology score, respiratory rate, mask comfort, serum sodium concentration, breathing pattern, diuretics, and vasoactive drugs, were all associated with the occurrence of thirst in ICU patients. The qualitative and quantitative results were integrated into 5 categories, namely personal characteristics and lifestyle, disease factors, treatment factors, psychological factors, and nurse factors.
Conclusions:
Thirst is a prevalent and severe issue among ICU patients, and effective interventions are required to address it. Considering its various causes, managing thirst in ICU patients should involve multiple levels of intervention. Treatment-related factors contribute significantly to thirst, and these factors should be taken into consideration when developing a thirst management strategy. Personal characteristics and lifestyle, psychological factors, drug-related factors, and nursing factors should be identified and optimized as soon as possible.
Implications For Clinical Practice:
Healthcare professionals should pay attention to thirst symptoms in ICU patients and promptly take effective preventive or intervention measures based on the influencing factors.

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
