The identification of adverse events in hip fracture patients using the Global Trigger Tool: A prospective observational cohort study

Surgical timing and clinical factor predicting in-hospital mortality in older adults with hip fractures: a neuronal network analysis

INTRODUCTION

Hip fractures in older adults are associated with a significant mortality rate, which has been reported to be around 35% within a year. Today, the incidence of these fractures is on the rise, and this trend is expected to increase even more owing to the aging of the population. Treatment timing and perioperative management of these patients are typically challenging owing to the presence of multiple comorbidities that are important risk factors for mortality after surgery. This study aims to evaluate the relationship between surgical timing and in-hospital mortality, analyzing the role of both acute events and chronic preexisting comorbidities in patient outcomes.

MATERIALS AND METHODS

This is a single-center, retrospective observational study (from January 2018 until June 2023). All consecutive patients ≥ 65 years with a diagnosis of proximal femur fracture were enrolled. The primary study endpoint was to evaluate risk factors associated with in-hospital mortality. The secondary endpoint was the assessment of the relationship between surgical timing and in-hospital mortality, including factors such as preexisting comorbidities, the Charlson Comorbidity Index, and the Nottingham Hip Fracture Score. The relative weight of each factor for predicting the mortality rate was also evaluated using neural network analysis, comparing patients treated within 24 h to those treated after a longer surgical delay.

RESULTS

Among the 2320 patients enrolled, 1391 (60%) underwent surgery within 24 h, while 929 patients (40%) were treated after 24 h. For patients who underwent surgery within 24 h, the in-hospital mortality was 2.8%, and for those who underwent surgery after 24 h, it was 5.2% (p = 0.046; odds ratio (OR) 1.58). Age (p = 0.001; OR 1.06) and Nottingham score (p = 0.04; OR 1.32) are factors predicting mortality. Acute infections were related to a high risk of mortality (p = 0.001; OR 5.99), both in patients treated within and after 24 h. Acute events, such as atrial fibrillation and electrolyte imbalance, were related to mortality risk only in patients treated within 24 h (p = 0.001 versus p = 0.51). Neural network analysis revealed that atrial fibrillation (AF), flutter, and electrolyte imbalance had the highest relative weight for mortality in patients treated in the first 24 h; by contrast, renal failure and pneumonia were most present in patients who died that were treated after 24 h.

CONCLUSIONS

Hip fracture is known to be a significant cause of morbidity and mortality in older adults. The impact of the timing of surgical treatment in those patients is crucial for postoperative outcomes. Early surgery is essential to reduce the risk of mortality. Our study has shown that, while in the case of acute and reversible conditions, waiting about 24 h to stabilize the patient with preoperative stabilization protocols, such as managing anticoagulation, optimizing hemodynamics, or addressing acute medical conditions including infection prevention, guarantees better results, in the case of sepsis or acute infection presence, the prolonged waiting to optimize patients before and after surgery does not help improve outcomes.

Timing of adverse events in patients undergoing acute and elective hip arthroplasty surgery: a multicentre cohort study using the Global Trigger Tool

OBJECTIVE

To explore timing in relation to all types of adverse events (AEs), severity and preventability for patients undergoing acute and elective hip arthroplasty.

DESIGN

A multicentre cohort study using retrospective record review with Global Trigger Tool methodology in combination with data from several registers.

SETTING

24 hospitals in 4 major regions of Sweden.

PARTICIPANTS

Patients ≥18 years, undergoing acute or elective total or hemiarthroplasty of the hip, were eligible for inclusion. Reviews of weighted samples of 1998 randomly selected patient records were carried out using Global Trigger Tool methodology. The patients were followed for readmissions up to 90 days postoperatively throughout the whole country.

RESULTS

The cohort consisted of 667 acute and 1331 elective patients. Most AEs occurred perioperatively and postoperatively (n=2093, 99.1%) and after discharge (n=1142, 54.1%). The median time from the day of surgery to the occurrence of AE was 8 days. The median days for different AE types ranged from 0 to 24.5 for acute and 0 to 71 for elective patients and peaked during different time periods. 40.2% of the AEs, both major and minor, occurred within postoperative days 0-5 and 86.9% of the AEs occurred within 30 days. Most of the AEs were deemed to be of major severity (n=1370, 65.5%) or preventable (n=1591, 76%).

CONCLUSIONS

A wide variability was found regarding the timing of different AEs with the majority occurring within 30 days. The timing and preventability varied regarding the severity. Most of the AEs were deemed to be preventable and/or of major severity. To increase patient safety for patients undergoing hip arthroplasty surgery, a better understanding of the multifaceted nature of the timing of AEs in relation to the occurrence of differing AEs is needed.

Timing of Adverse Events Within 90 Days of Hip Fracture Surgery: A Database Study

INTRODUCTION

Hip fracture surgery is associated with notable morbidity. Understanding the timing of adverse events can inform strategies for prevention and management. Owing to database limitations, many studies have limited postoperative follow-up to 30 days. However, adverse events may not have plateaued by this time. This study evaluated adverse events after hip fracture surgery out to 90 days.

METHODS

Hip fracture surgeries in patients 65 years or older were identified in the 2010 to 2020 Q3 M91Ortho PearlDiver data set using administrative codes. The 90-day incidence and time of diagnosis of 10 common adverse events were determined and used to calculate median, interquartile range, and middle 80% for time of diagnosis. The number of events occurring before and after 30 days was also determined.

RESULTS

A total of 258,834 hip fracture surgery patients were identified. On average, 70% of adverse events occurred in postoperative days 0 to 30 and 30% occurred in days 31 to 90. The percentage of events in days 31 to 90 ranged from 8% (transfusion) to 42% (wound dehiscence). Compared with patients with a 0- to 30-day adverse event, those with 31- to 90-day adverse events had higher average Elixhauser Comorbidity Index scores (8.6 vs. 7.8, P < 0.001) and a slightly greater proportion of men (31.5% vs. 30.2%, P < 0.001).For specific adverse events, the time of diagnosis (median; interquartile range; middle 80%) were as follows: transfusion (2 days; 1 to 4 days; 1 to 24 days), acute kidney injury (5; 2 to 26; 1 to 55), cardiac event (9; 3 to 35; 1 to 64), urinary tract infection (13; 3 to 39; 1 to 65), hematoma (14; 6 to 28; 3 to 52), pneumonia (15; 5 to 39; 2 to 66), venous thromboembolism (16; 5 to 40; 2 to 64), surgical site infection (23; 14 to 37; 7 to 56), sepsis (24; 9 to 48; 3 to 71), and wound dehiscence (26; 15 to 41; 7 to 64).

DISCUSSION

Nearly one-third of 90-day adverse events after hip fracture surgery were found to occur after postoperative day 30. An understanding of the timing of adverse events is important for improving patient counseling and optimizing patient care.

A co-created nurse-driven catheterisation protocol can reduce bladder distension in acute hip fracture patients - results from a longitudinal observational study

Background

Urinary retention is common in elderly patients undergoing acute hip fracture surgery. Avoiding overfilling the urinary bladder is important to avoid detrusor muscle damage and associated motility problems. The aim of this study was to analyse associations between the co-creation of a nurse-driven urinary catheterisation protocol and the incidence of bladder distension in patients undergoing hip fracture surgery.

Methods

This is a single-centre implementation intervention with a retrospective longitudinal observation design, using five measures points, spanning from June 2015 to March 2020. The intervention was theory driven and the participants, together with the facilitators and researcher, co-created a nurse-driven urinary catheterisation protocol. Data were retrieved from the hip fracture register. Uni- and multivariable logistic regressions were used for analyses of changes in bladder distension and urinary volume of ≥500 ml over the years.

Results

A total of 3078 patients were included over a five-year period. The implementation intervention was associated with a reduction in the proportion of patients with bladder distension of 31.5% (95% confidence interval 26.0–37.0), from year 1 to year 5. The multivariable analysis indicated a 39% yearly reduction in bladder distension, OR 0.61 (95% confidence interval 0.57–0.64, p <  0001). There was a reduction in the proportion of patients with a bladder volume of ≥500 ml of 42.8% (95% confidence interval 36.2–49.4), from year 1 to year 5. The multivariable analysis found a 41% yearly reduction in patients with a bladder volume of ≥500 ml, OR 0.59 (95% confidence interval 0.55–0.64, p <  0.0001). The intervention was associated with improved documentation of both catheter indications and removal plans.

Conclusion

The use of predefined catheter indications and a tighter bladder scanning schedule were associated with a reduction in the incidence of both bladder distension and urine volume ≥ 500 ml in hip fracture patients. Registered nurses can play an active role in the facilitation of timely and appropriate catheter treatment in patients with hip fractures.

Variation in detected adverse events using trigger tools: A systematic review and meta-analysis

Background

Adverse event (AE) detection is a major patient safety priority. However, despite extensive research on AEs, reported incidence rates vary widely.

Objective

This study aimed: (1) to synthesize available evidence on AE incidence in acute care inpatient settings using Trigger Tool methodology; and (2) to explore whether study characteristics and study quality explain variations in reported AE incidence.

Design

Systematic review and meta-analysis.

Methods

To identify relevant studies, we queried PubMed, EMBASE, CINAHL, Cochrane Library and three journals in the patient safety field (last update search 25.05.2022). Eligible publications fulfilled the following criteria: adult inpatient samples; acute care hospital settings; Trigger Tool methodology; focus on specialty of internal medicine, surgery or oncology; published in English, French, German, Italian or Spanish. Systematic reviews and studies addressing adverse drug events or exclusively deceased patients were excluded. Risk of bias was assessed using an adapted version of the Quality Assessment Tool for Diagnostic Accuracy Studies 2. Our main outcome of interest was AEs per 100 admissions. We assessed nine study characteristics plus study quality as potential sources of variation using random regression models. We received no funding and did not register this review.

Results

Screening 6,685 publications yielded 54 eligible studies covering 194,470 admissions. The cumulative AE incidence was 30.0 per 100 admissions (95% CI 23.9–37.5; I² = 99.7%) and between study heterogeneity was high with a prediction interval of 5.4–164.7. Overall studies’ risk of bias and applicability-related concerns were rated as low. Eight out of nine methodological study characteristics did explain some variation of reported AE rates, such as patient age and type of hospital. Also, study quality did explain variation.

Conclusion

Estimates of AE studies using trigger tool methodology vary while explaining variation is seriously hampered by the low standards of reporting such as the timeframe of AE detection. Specific reporting guidelines for studies using retrospective medical record review methodology are necessary to strengthen the current evidence base and to help explain between study variation.

Onset PrevenTIon of urinary retention in Orthopaedic Nursing and rehabilitation, OPTION-a study protocol for a randomised trial by a multi-professional facilitator team and their first-line managers' implementation strategy

BACKGROUND

The Onset PrevenTIon of urinary retention in Orthopaedic Nursing and rehabilitation, OPTION, project aims to progress knowledge translation vis-à-vis evidence-based bladder monitoring in orthopaedic care, to decrease the risk of urinary retention, and voiding complications. Urinary retention is common whilst in hospital for hip surgery. If not properly identified and managed, there is a high risk of complications, some lifelong and life threatening. Although evidence-based guidelines are available, the implementation is lagging.

METHODS

Twenty orthopaedic sites are cluster randomised into intervention and control sites, respectively. The intervention sites assemble local facilitator teams among nursing and rehabilitation staff, including first-line managers. The teams receive a 12-month support programme, including face-to-face events and on-demand components to map and bridge barriers to guideline implementation, addressing leadership behaviours and de-implementation of unproductive routines. All sites have access to the guidelines via a public healthcare resource, but the control sites have no implementation support. Baseline data collection includes structured assessments of urinary retention procedures via patient records, comprising incidence and severity of voiding issues and complications, plus interviews with managers and staff, and surveys to all hip surgery patients with interviews across all sites. Further assessments of context include the Alberta Context Tool used with staff, the 4Ps tool for preference-based patient participation used with patients, and data on economic aspects of urinary bladder care. During the implementation intervention, all events are recorded, and the facilitators keep diaries. Post intervention, the equivalent data collections will be repeated twice, and further data will include experiences of the intervention and guideline implementation. Data will be analysed with statistical analyses, including comparisons before and after, and between intervention and control sites. The qualitative data are subjected to content analysis, and mixed methods are applied to inform both clinical outcomes and the process evaluation, corresponding to a hybrid design addressing effectiveness, experiences, and outcomes.

DISCUSSION

The OPTION trial has a potential to account for barriers and enablers for guideline implementation in the orthopaedic context in general and hip surgery care in particular. Further, it may progress the understanding of implementation leadership by dyads of facilitators and first-line managers.

TRIAL REGISTRATION

The study was registered as NCT04700969 with the U.S. National Institutes of Health Clinical Trials Registry on 8 January 2021, that is, prior to the baseline data collection.
