A Multicenter Cohort Study of Falls Among Patients Admitted to the ICU

Incidence and Associated Risk Factors for Falls in Adults Following Critical Illness: An Observational Study

OBJECTIVE

To explore the incidence of falls and associated risk factors in the first year after hospital discharge in survivors of critical illness.

DESIGN

Prospective single-site observational study.

SETTING

University-affiliated mixed ICU.

PATIENTS

One hundred ICU adults who required invasive ventilation for 48 hours and in an ICU for at least 4 days.

INTERVENTIONS

Not applicable.

MEASUREMENTS AND MAIN RESULTS

Falls were monitored prospectively for 1 year with completion of monthly falls calendars. Falls data included the number of people who had falls/no falls/recurrent falls, falls rate per person per year, and time to first fall. Fall severity was classified according to the Schwenck classification scheme to examine injurious falls requiring medical intervention. Other outcomes considered included assessments of balance, strength, function, cognition, psychologic health, and health-related quality of life. One hundred participants (31% female) were recruited with a mean age of 58.3 ± 16.2 years, and a median ventilation duration of 6.3 days [4.0-9.1]. Sixty-one percent fell at least once in the first year with the majority sustaining two or more falls (81.4%) and one in four sustained an injurious fall requiring medical attention. The falls incidence rate was 4.4 falls per person-year (95% CI, 3.2-5.9), with the highest incidence occurring less than 3 months after hospital discharge (5.9 falls/person-year [95% CI, 4.4-7.8]). Time to first fall or injurious fall was 36 [11-66] and 95 (95% CI, 40-155) days, respectively. Key risk factors for falls at the time of hospital discharge include comorbidities, higher discharge medications, balance, and muscle strength.

CONCLUSIONS

There was a high falls incidence in ICU survivors. The study findings suggest a critical window may exist within the first 3 months after hospital discharge and the need for screening, pharmacological optimization, and exercise training in this patient group.

Patient safety in the intensive care department

Patient safety is a priority for all healthcare systems. Despite this, too many patients still suffer harm as a consequence of healthcare. Furthermore, it has a significant impact on family members, professionals and healthcare institutions, resulting in considerable economic costs. The critically ill patient is particularly vulnerable to adverse events. Numerous safe practices have been implemented, acknowledging the influence of human factors on safety and the significance of the well-being of professionals, as well as the impact of critical episodes at hospital discharge on patients and their families. Training and engagement of professionals, patients and families are of paramount importance. Recently, artificial intelligence has demonstrated its ability to enhance clinical safety. This update on "Patient Safety" reviews all these aspects related to one of the most pivotal dimensions of healthcare quality.

Impact of Collaborative Nursing Care Delivery on Patient Safety Events in an Emergency Intensive Care Unit: A Retrospective Observational Study

OBJECTIVES

Patient safety events (PSEs) have detrimental consequences for patients and healthcare staff, highlighting the importance of prevention. Although evidence shows that nurse staffing affects PSEs, the role of an appropriate nursing care delivery system remains unclear. The current study aimed to investigate whether nursing care delivery systems could prevent PSEs.

METHODS

This retrospective study was conducted in Japan. The study examined the collaborative 4:2 nursing care delivery system in which 2 nurses are assigned to care for 4 patients, collaborating to perform tasks, and provide care. The cohort receiving care from a collaborative 4:2 nursing care delivery system was labeled the postintervention, whereas the cohort receiving care from a conventional individualized system, in which one nurse provides care for 2 patients, was labeled the preintervention. The primary outcome was the occurrence of PSEs.

RESULTS

The preintervention and postintervention comprised 561 and 401 patients, respectively, with the latter consisting of a younger and more critically ill population. The number of PSEs per 1000 patient-days was not significantly different between the 2 groups (10.3 [95% confidence interval, 7.1-13.5] versus 6.0 [95% confidence interval, 3.2-8.9], P = 0.058). Multiple logistic regression analysis showed that the collaborative 4:2 nursing care delivery system was significantly associated with PSEs (adjusted odds ratio, 0.53; 95% confidence interval, 0.29-0.95; P = 0.037).

CONCLUSIONS

These findings suggest that in an emergency intensive care unit, a collaborative nursing care delivery system was associated with a decrease in PSEs.

Evidence-Based Pearls

Falls in the ICU are multifaceted, affecting patients of all ages. Historically, falls have been associated with patients in the hospital environment, but fall rates after discharge and readmission rates following a fall are now areas of concern. Recent innovations to prevent risks related to sedation and immobility in the hospital have revealed their impact on ICU patients and fall risk. Risk factors for falls in the ICU relate to length of stay and acuity-related care requirements, such as mechanical ventilation, sedation, and prolonged immobilization. Evidence-based fall prevention includes screening tools, prevention bundles/programs, and implementing clinical practice guidelines.
