Post-Vacuum-Assisted Stereotactic Core Biopsy Clip Displacement: A Comparison Between Commercially Available Clips and Surgical Clip.

PURPOSE: The placement of localization clips following percutaneous biopsy is a standard practice for a variety of situations. Subsequent clip displacement creates challenges for imaging surveillance and surgical planning, and may cause confusion amongst radiologists and between surgeons and radiologists. Many causes have been attributed for this phenomenon including the commonly accepted "accordion effect." Herein, we investigate the performance of a low cost surgical clip system against 4 commercially available clips. METHODS: We retrospectively reviewed 2112 patients who underwent stereotactic vacuum-assisted core biopsy followed by clip placement between January 2013 and June 2016. The primary performance parameter compared was displacement >10 mm following vacuum-assisted stereotactic core biopsy. Within the group of clips that had displaced, the magnitude of displacement was compared. RESULTS: There was a significant difference in displacement among the clip types (P < .0001) with significant pairwise comparisons between pediatric surgical clips and SecureMark (38% vs 28%; P = .001) and SenoMark (38% vs 27%; P = .0001) in the proportion displaced. The surgical clips showed a significant magnitude of displacement of approximately 25% greater average distance displaced. CONCLUSIONS: As a whole, the commercial clips performed better than the surgical clip after stereotactic vacuum-assisted core biopsy suggesting the surrounding outer component acts to anchor the central clip and minimizes clip displacement. The same should apply to tomosynthesis-guided biopsy.

Efficiency gains from a standardised approach to older people presenting to the emergency department after a fall.

Objective Falls are a major cause of hospital-related costs in people aged ≥65 years. Despite this, falls are often seen as trivial and given low priority in an emergency department (ED), especially in the absence of overt major injury. ED systems that care for falls patients are often inefficient. The aims of this study were to: (1) design and implement a standardised and systematic approach to patients presenting to an ED after a fall; and (2) achieve hospital efficiency gains, such as reduced hospital length of stay, through implementation of this approach. Methods A prospective study was conducted with pre- and postintervention measurement of outcomes. The key features of the intervention were direct admission to an ED short stay unit, standardised assessment of cognition, medications, mobility and discharge risk, and access in the ED to a geriatric consultation service for complex patients. Results In the 12 months of the intervention, 1435 male and female patients aged ≥65 years were enrolled in the study. At the end of 12 months, these patients had significantly higher ED discharge (66% vs 46%; P<0.001) and, if admitted, shorter median hospital stays (6 vs 2 days; P<0.001) compared with the baseline pre-intervention phase. Analysis 1 year later revealed that these outcomes were sustained or further improved. Conclusion A systematic approach to falls in older patients attending the ED is feasible and beneficial. Decreased hospital stay and improved rates of effective discharge from ED back to the community are achievable and sustainable. What is known about the topic? Falls are common, serious and costly. Not identifying and managing falls risk factors is a common feature of ED practice. As a result, admission rates to hospital for patients who fall are high. What does this paper add? In this large study we have shown that a systematic approach to falls assessment is feasible, sustainable and results in higher discharge rates from the ED. What are the implications for practitioners? EDs are the gateway to a hospital bed. It is possible to redesign ED flow and bring front-loaded multidisciplinary geriatric care into an ED short stay environment, to the benefit of patients and health systems.

A randomized-controlled trial of a patient-centred intervention in high-risk discharged older patients.

BACKGROUND: The risk of early reattendance after discharge has been proposed as a performance indicator for emergency departments (EDs), but is not uniform in all patients. Those individuals at the highest risk of reattendance may benefit from an intense intervention to reduce this risk, and our objective was to test this hypothesis in a clinical trial. METHODS: A randomized-controlled trial was conducted in the EDs of two hospitals. Very high-risk adults aged 65 years and older, identified using a validated risk-prediction nomogram and being discharged from ED, were randomized to receive a postdischarge patient-centred intervention or standard care. The intervention focused on identifying and supporting patients to address risk factors for future hospital presentation. The primary outcome measure was any unplanned ED reattendance within 28 days. Secondary outcomes included 28-day and 1-year hospital usage, institutionalization and death. RESULTS: We enrolled 164 patients, 82 in each study arm. There was an 8% absolute (95% confidence interval: -7%-20%) and a 20% relative risk reduction for an intervention patient making an unplanned ED reattendance within 28 days. This difference was not statistically significant (P=0.26). CONCLUSION: This postdischarge intervention was associated with only small and nonsignificant reductions in ED reattendance.

Use of a risk nomogram to predict emergency department reattendance in older people after discharge: a validation study.

In older people, revisit to the emergency department (ED) in the short period after discharge is not entirely avoidable, but in a proportion of cases is preventable, and should ideally be minimised. We have previously derived a risk probability nomogram to predict the likelihood of revisit. In this study, we sought to validate the nomogram for use as a general risk stratification tool for use in older people being discharged from ED. We conducted a prospective cohort study, applying the nomogram to consecutive community dwelling discharged patients aged 65 and over. Patients were followed up at 28 days post-discharge to determine whether there had been any unplanned ED revisit in that period. We cross tabulated predicted risk versus revisit rates. In 1143 study subjects, we find the odds of revisit increases progressively with increasing strata of predicted risk, culminating in an OR of 9.7 (95% CI 4.7-19.9) in the highest risk group. The 28-day revisit rates across strata range from 16% through 65%, with the difference between strata being statistically highly significant (p < 0.001). The area under the ROC curve is 0.65. We conclude that the risk nomogram can classify older people discharged from ED into risk strata, and has modest overall predictive value.
