Effectiveness of Implementing Evidence‐based Interventions to Reduce C‐spine Image Ordering in the Emergency Department: A Systematic Review

Objectives

Appropriate use of imaging for adult patients with cervical spine (C‐spine) injuries in the emergency department (ED) is a longstanding issue. Guidance for C‐spine ordering exists; however, the effectiveness of the decision support implementation in the ED is not well studied. This systematic review examines the implementation and effectiveness of evidence‐based interventions aimed at reducing C‐spine imaging in adults presenting to the ED with neck trauma.

Methods

Six electronic databases and the gray literature were searched. Comparative intervention studies were eligible for inclusion. Two independent reviewers screened for study eligibility, study quality, and extracted data. The change in imaging was reported using individual odds ratios (ORs) with 95% confidence intervals (CIs) using random effects.

Results

A total of 990 unique citations were screened for relevance of which six before–after studies and one randomized controlled trial were included. None of the studies were assessed as high quality. Interventions consisted primarily of locally developed guidelines or established clinical decision rules such as the NEXUS or the Canadian C‐spine rule. Overall, implementation of interventions aimed at reducing C‐spine image ordering resulted in a statistically significant reduction in imaging (OR = 0.69, 95% CI = 0.51–0.93); however, heterogeneity was high (I² = 82%). Subgroup analysis revealed no differences between studies that specified enrolling alert and stable patients compared to unspecified trauma (p = 0.81) or between studies employing multifaceted versus nonmultifaceted interventions (p = 0.66). While studies generally provided details on implementation strategies (e.g., teaching sessions, pocket cards, posters, computerized decision support) the effectiveness of these implementation strategies were frequently not reported.

Conclusion

There is moderate evidence regarding the effectiveness of interventions to reduce C‐spine image ordering in adult patients seen in the ED with neck trauma. Given the national and international focus on improving appropriateness and reducing unnecessary C‐spine imaging through campaigns such as Choosing Wisely, additional interventional research in this field is warranted.

     

Development of a Patient Decision Aid for Syncope in the Emergency Department: the SynDA Tool

Objectives

The objective was to develop a patient decision aid (DA) to promote shared decision making (SDM) for stable, alert patients who present to the emergency department (ED) with syncope.

Methods

Using input from patients, clinicians, and experts in the field of syncope, health care design, and SDM, we created a prototype of a paper‐based DA to engage patients in the disposition decision (admission vs. discharge) after an unremarkable ED evaluation for syncope. In phase 1, we conducted one‐on‐one semistructured exploratory interviews with 10 emergency physicians and 10 ED syncope patients. In phase 2, we conducted one‐on‐one directed interviews with 15 emergency care clinicians, five cardiologists, and 12 ED syncope patients to get detailed feedback on DA content and design. We iteratively modified the aid using feedback from each interviewee until clarity and usability had been optimized.

Results

The 11 × 17‐inch, paper‐based DA, titled SynDA, includes four sections: 1) explanation of syncope, 2) explanation of future risks, 3) personalized 30‐day risk estimate, and 4) disposition options. The personalized risk estimate is calculated using a recently published syncope risk‐stratification tool. This risk estimate is stated in natural frequency and graphically displayed using a 100‐person color‐coded pictogram. Patient‐oriented questions are included to stimulate dialogue between patient and clinician. At the end of the development process, patient and physician participants expressed satisfaction with the clarity and usability of the DA.

Conclusions

We iteratively developed an evidence‐based DA to facilitate SDM for alert syncope patients after an unremarkable ED evaluation. Further testing is required to determine its effects on patient care. This DA has the potential to improve care for syncope patients and promote patient‐centered care in emergency medicine.

     

Outcomes of Patients With Syncope and Suspected Dementia

Objectives

Syncope and near‐syncope are common in patients with dementia and a leading cause of emergency department (ED) evaluation and subsequent hospitalization. The objective of this study was to describe the clinical trajectory and short‐term outcomes of patients who presented to the ED with syncope or near‐syncope and were assessed by their ED provider to have dementia.

Methods

This multisite prospective cohort study included patients 60 years of age or older who presented to the ED with syncope or near‐syncope between 2013 and 2016. We analyzed a subcohort of 279 patients who were identified by the treating ED provider to have baseline dementia. We collected comprehensive patient‐level, utilization, and outcomes data through interviews, provider surveys, and chart abstraction. Outcome measures included serious conditions related to syncope and death.

Results

Overall, 221 patients (79%) were hospitalized with a median length of stay of 2.1 days. A total of 46 patients (16%) were diagnosed with a serious condition in the ED. Of the 179 hospitalized patients who did not have a serious condition identified in the ED, 14 (7.8%) were subsequently diagnosed with a serious condition during the hospitalization, and an additional 12 patients (6.7%) were diagnosed postdischarge within 30 days of the index ED visit. There were seven deaths (2.5%) overall, none of which were cardiac‐related. No patients who were discharged from the ED died or had a serious condition in the subsequent 30 days.

Conclusions

Patients with perceived dementia who presented to the ED with syncope or near‐syncope were frequently hospitalized. The diagnosis of a serious condition was uncommon if not identified during the initial ED assessment. Given the known iatrogenic risks of hospitalization for patients with dementia, future investigation of the impact of goals of care discussions on reducing potentially preventable, futile, or unwanted hospitalizations while improving goal‐concordant care is warranted.

     

Interventions to Improve Care Related to Colorectal Cancer Among Racial and Ethnic Minorities: A Systematic Review

Objective

To systematically review the literature to identify interventions that improve minority health related to colorectal cancer care.

Data sources

MEDLINE, PsycINFO, CINAHL, and Cochrane databases, from 1950 to 2010.

Study eligibility criteria, participants, and interventions

Interventions in US populations eligible for colorectal cancer screening, and composed of ??50?% racial/ethnic minorities (or that included a specific sub-analysis by race/ethnicity). All included studies were linked to an identifiable healthcare source. The three authors independently reviewed the abstracts of all the articles and a final list was determined by consensus. All papers were independently reviewed and quality scores were calculated and assigned using the Downs and Black checklist.

Results

Thirty-three studies were included in our final analysis. Patient education involving phone or in-person contact combined with navigation can lead to modest improvements, on the order of 15 percentage points, in colorectal cancer screening rates in minority populations. Provider-directed multi-modal interventions composed of education sessions and reminders, as well as pure educational interventions were found to be effective in raising colorectal cancer screening rates, also on the order of 10 to 15 percentage points. No relevant interventions focusing on post-screening follow up, treatment adherence and survivorship were identified.

Limitations

This review excluded any intervention studies that were not tied to an identifiable healthcare source. The minority populations in most studies reviewed were predominantly Hispanic and African American, limiting generalizability to other ethnic and minority populations.

Conclusions and implications of key findings

Tailored patient education combined with patient navigation services, and physician training in communicating with patients of low health literacy, can modestly improve adherence to CRC screening. The onus is now on researchers to continue to evaluate and refine these interventions and begin to expand them to the entire colon cancer care continuum.
