Thirst in adult patients in the intensive care unit: protocol for a scoping review

Thirst in adult patients in the intensive care unit: A scoping review

PURPOSE

To review the literature on thirst in intensive care unit (ICU) patients and report potential causes, risk factors, diagnosis and measurement tools, as well as potential co-occurrence with other distressing symptoms, and the management of thirst in the ICU.

DESIGN

A scoping review employing the Joanna Briggs Institute methodology.

METHODS

PubMed, MEDLINE, EMBASE and CINAHL were searched from inception to April 2024. Any type of empirical study reporting thirst or associated xerostomia in adult patients (≥18 years) admitted to an ICU or high dependency unit for more than 24 h were included.

RESULTS

The search yielded 907 unique records, and after evaluating 65 full-text publications, 21 studies were included. Thirst intensity was addressed most often (eleven studies), whereas the experience (or quality) of thirst and the validation of a measurement instrument, were addressed in only one study. Although co-occurrence of symptoms was addressed in four studies, only one pilot study looked into the interaction of thirst with other symptoms. Intervention studies have been focussing primarily on mouth-care interventions.

CONCLUSION

Thirst is a distressing symptom in the ICU, with reported high prevalence and intensity. Knowledge about its causes, interventions that incorporate minimising its risk, occurrence and intensity are limited.

IMPLICATIONS FOR CLINICAL PRACTICE

Health care providers should acknowledge thirst as a prominent symptom for ICU patients. They should possess knowledge on the factors that potentially evoke or aggravate thirst. Regular and timely relief of thirst by oral care with cold swabs and the application of menthol can be regarded as a first choice of intervention.

Measuring the intensive care experience of intensive care unit patients: A cross-sectional study in western China

BACKGROUND

The negative experiences of intensive care unit (ICU) patients seriously affect their quality of life and survival outcomes. Thus, it is of great significance to evaluate the monitoring experience of ICU patients for the clinical improvement of their experiences and promote interventions.

OBJECTIVES

The objective of this study was to investigate patients' experiences of ICU and to understand the sources of patient experience and influencing factors.

METHODS

From November 2021 to September 2022, a cross-sectional survey was conducted with 600 inpatients from four grade A-III hospitals in western China. Data were collected using the Chinese version of the Intensive Care Experience Questionnaire.

RESULTS

585 valid questionnaires were collected, the response rate was 97.5%. ICU patients in western China scored below-the-average for their intensive care experience. Family monthly income, occupation types, medical payment method, type of ICU, ICU admission plan, ICU admission times, mechanical ventilation use, fertility status, analgesia, sedation, and Acute Physiology and Chronic Health Evaluation II scores are important factors influencing ICU patients' intensive care experience.

CONCLUSIONS

Medical staff need to pay attention to patient experience, improve the awareness of patient stressors and influencing factors, design nursing programs conducive to patient-positive experience, and promote interventions to further improve the long-term prognosis of patients. The results of this study can also be used as a set of nursing-sensitive indicators for evaluating nursing structure, process, and outcomes.
