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.

Fall Prevention after Hip and Knee Arthroplasty

Despite the success of total knee arthroplasty and total hip arthroplasty, patients face an increased risk of postoperative falls, often due to surgery-induced changes in muscle strength. Falls can lead to serious consequences, including fractures and reduced quality of life. The majority of falls related to total joint arthroplasty occurs outside the hospital. Effective fall prevention strategies, such as patient education, exercise interventions, environmental modifications, and medication management, are crucial for reducing fall risks and improving patient outcomes. Continued research and innovation in fall prevention are essential for improving patient safety and well-being following joint arthroplasty.

The impact of mental state altering medications on preventable falls after total hip or total knee arthroplasty: a systematic review and meta-analysis

BACKGROUND

Joint replacement surgery of the lower extremities are common procedures in elderly persons who are at increased risk of postoperative falls. The use of mental state altering medications, such as opioids, antidepressants or benzodiazepines, can further contribute to impaired balance and risk of falls. The objective of the current systematic review was to evaluate the risk of the use of mental state altering medications on postoperative falls in patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA).

METHODS

A comprehensive search of Medline, Embase and Cochrane Controlled Trials Register was conducted from 1 October 1975 to 1 September 2021. The search was repeated in may 2023 and conducted from 1 October 1975 to 1 June 2023. Clinical trials that evaluated the risk of medication on postoperative THA and TKA falls were eligible for inclusion. Articles were evaluated independently by two researchers for risk of bias using the Newcastle-Ottawa Scale. A meta-analysis was performed to determine the potential effect of postoperative use of mental state altering medications on the risk of falls. Lastly, a qualitative synthesis was conducted for preoperative mental state altering medications use.

RESULTS

Seven cohort studies were included, of which five studies focussed on the postoperative use of mental state altering medications and two investigated the preoperative use. Meta-analysis was performed for the postoperative mental state altering medications use. The postoperative use of mental state altering medications was associated with fall incidents (OR: 1.81; 95% CI: 1.04; 3.17) (p < 0.01) after THA and TKA. The preoperative use of opioids > 6 months was associated with a higher risk of fall incidents, whereas a preoperative opioid prescription up to 3 months before a major arthroplasty had a similar risk as opioid-naïve patients.

CONCLUSIONS

The postoperative use of mental state altering medications increases the risk of postoperative falls after THA and TKA. Prior to surgery, orthopaedic surgeons and anaesthesiologists should be aware of the associated risks in order to prevent postoperative falls and associated injuries.

Life After Total Hip Replacement: A Qualitative Study on Patient Experiences

The present study aimed to determine the life experiences of patients undergoing total hip replacement. This study was a qualitative study conducted using the content analysis method. Using purposive sampling, 10 patients with total hip replacement were selected and interviewed. Data were collected using semistructured interviews and were analyzed using the content analysis method. The mean age of the 10 patients was 59.33 ± 9.9 years. Six patients were female and four were male. Of these 10 participants, eight were married and had nuclear families; all participants were literate, and seven belonged to the middle-income group. Four main themes and 10 subthemes were identified. The themes included a painful process (severe pain and feeling of pain due to emotional exhaustion), fear (fear of feeling pain, fear of moving, and fear of recurrence), difficulty (self-care, sleep, and participation in social life), and positive thinking about life (feeling good and hope). The participants expressed mostly negative life experiences while also pointing out the positive life experiences. This study provides an in-depth understanding of the views of patients with total hip replacement on life experiences. These results can be used in planning and implementing health services for patients with total hip replacement.

A 2-min cognitive screener for predicting 1-year functional recovery and survival in older adults after hip fracture repair

BACKGROUND

Implementing cognitive assessment in older people admitted to hospital with hip fracture - lying in bed, experiencing pain - is challenging. We investigated the value of a quick and easy-to-administer 10-point cognitive screener (10-CS) in predicting 1-year functional recovery and survival after hip surgery.

METHODS

Prospective cohort study comprising 304 older patients (mean age=80.3±9.1 years; women=72%) with hip fracture consecutively admitted to a specialized academic medical center that supports secondary hospitals in Sao Paulo Metropolitan Area, Brazil. The 10-CS, a 2-minute bedside tool including temporal orientation, verbal fluency, and three-word recall, classified patients as having normal cognition, possible cognitive impairment, or probable cognitive impairment on admission. Outcomes were time-to-recovery activities of daily living (ADLs; Katz index) and mobility (New Mobility Score), and survival during 1-year after hip surgery. Hazard models, considering death as a competing risk, were used to associate the 10-CS categories with outcomes after adjusting for sociodemographic and clinical measures.

RESULTS

On admission, 144 (47%) patients had probable cognitive impairment. Compared to those cognitively normal, patients with probable cognitive impairment presented less postsurgical recovery of ADLs (77% vs. 40%; adjusted sub-hazard ratio [HR]=0.44; 95%CI=0.32-0.62) and mobility (50% vs. 30%; adjusted sub-HR=0.52; 95%CI=0.34-0.79), and higher risk of death (15% vs. 40%; adjusted HR=2.08; 95%CI=1.03-4.20) over 1-year follow-up.

CONCLUSIONS

The 10-CS is a strong predictor of functional recovery and survival after hip fracture repair. Cognitive assessment using quick and easy-to-administer screening tools like 10-CS can help clinicians make better decisions and offer tailored care for older patients admitted with hip fracture.
