Impact of sound levels on physiological and consciousness state of cardiovascular patients.

Nurs Crit Care 2022 03 20;27(2):240-250. Epub 2022 Jan 20.

Department of Nursing, Instituto Maimónides de Investigación Biomédica de Córdoba (IMIBIC), Córdoba, Spain.

Background: Patients treated in intensive care units (ICUs) experience life-threatening medical conditions but some external factors in ICUs do not help or even adversely affect and complicate their evolution. Among others, such factors include noise pollution due to alarms and medical clinical equipment, as well as the activities of the health care personnel themselves.

Aim: This study aimed to evaluate the influence of elevated sound levels on physiological variables and the consciousness state of patients treated in a cardiovascular area in an ICU.

Design: A longitudinal study with several observations was carried out during 1 month in the cardiovascular area of an ICU of a third-level hospital in southern Spain.

Methods: Sound levels were monitored in different work shifts and patients' physiological data and consciousness status were recorded. Generalized additive mixed models (GAMMs) were developed to detect the variability of the sound levels together with the vital parameters of the patients in the ICU.

Results: Thirty-eight patients were included. The mean sound level was 54.09 dBA. The GAMM sound levels analysis showed a significant increase in sound levels from 4:30 p.m. to 8:00 p.m. (1.83 dBA; P < .001) and 8:00 p.m. to 11:30 p.m. (3.06 dBA; P < .001). An increase in heart rate (3.66 bpm; P < .001), respiratory rate (2.62 rpm; P < .001) and the Glasgow Coma Scale (0.50 units; P = .002) was detected during the 4:30 p.m.-8:30 p.m.


Conclusions: Elevated sound levels in cardiovascular ICUs seem to influence positively the physiological and consciousness status of patients. Given the importance of the findings for patient safety, future intervention studies are recommended.

Relevance To Clinical Practice: The finding of this study could translate into structural changes in ICU facilities, as well as the development of clinical practice guidelines that influence the behaviour of health care professionals.

Severe trauma patients and nursing practice-associated infections.

Int J Nurs Pract 2020 Oct 26;26(5):e12853. Epub 2020 May 26.

Department of Nursing, Maimonides Biomedical Research Institute of Cordoba (IMIBIC), Córdoba, Spain.

Aims: Our study examined factors influencing the development of healthcare-associated infections in the intensive care unit (ICU) of a tertiary hospital in southern Spain.

Background: Healthcare-associated infections are a frequent adverse event, significantly lengthening patient stays in the ICU. Nursing practice is a key factor in the infection control process.

Design: A retrospective longitudinal study with two observation periods (admission and discharge) was performed in an ICU of a tertiary hospital.

Methods: We analysed patient records for those admitted to this unit coded as CIE 800-959.9 from 2012 to 2016. Using binomial logistic regression analysis, we analysed factors associated with healthcare-associated infections.

Results: We analysed 375 records (men: 78.1%; average age: 46.63 years). Of these, 9.2% patients acquired a healthcare-associated infection during their stay. Nursing practice-related factors significantly associated with the development of infection were the number of days connected to mechanical ventilation and the number of days in the ICU.

Conclusion: Healthcare-associated infections in patients with severe trauma admitted to the ICU are mainly associated with the management of invasive techniques. A multidisciplinary approach should focus on the review of action and care plans.
