Predictive validity of the Spinal Cord Injury Pressure Ulcer Scale (SCIPUS) in acute care and inpatient rehabilitation in individuals with traumatic spinal cord injury

Development of a decision support tool to prevent community acquired pressure injuries for use in the spinal cord injury clinic using the delphi technique

STUDY DESIGN

Delphi Technique.

OBJECTIVES

Describe the development of a decision support tool to prevent community-acquired pressure injuries (CAPrIs) in individuals with spinal cord injury (SCI) for use in SCI clinics, called the Community-Acquired Pressure Injury Prevention-Field Implementation Tool (CAPP-FIT).

SETTING

Veteran Health Administration Hospital, Chicago, Illinois, USA.

METHODS

Concept mapping of current pressure injury (PrI) guidelines and qualitative research describing risks, actions, and resources needed to prevent CAPrIs associated with SCI were used to develop 40 veteran checklist items (Items) along with 37 associated provider actions (Actions) for the tool. The Delphi technique was used to refine Items and Actions with a panel of interprofessional SCI providers (n = 15), veterans with SCI (n = 4), and caregivers (n = 3) to determine consensus on a 4-point Likert scale (strongly agree-strongly disagree) for each Item and Action. A 75% agreement was set for responses rated as strongly agree or agree.

RESULTS

Panelists were 60% female, 62% White, 33% veterans with SCI or caregivers, 33% wound care certified with a mean age of 59 years. Two survey rounds were required for consensus for 41 Item and 38 Action CAPP-FIT. Response rate was 95% for both rounds. Delphi round 1 showed all but two Actions affirming agreement above 75%. Substantive comments from panelists required revision to 5 Items and 9 Actions and one additional Item/Actions related to coping, meeting threshold percent agreement in Round 2.

CONCLUSIONS

The CAPP-FIT could become a useful tool for Veterans living with SCI, caregivers, and SCI providers.

IMPACT OF SURGERY ON AMBULATORY STATUS IN PATIENTS WITH SYMPTOMATIC NEOPLASTIC SPINAL CORD COMPRESSION IN SOUTHERN BRAZIL

ABSTRACT Background: Spinal cord compression is a common complication of spine metastasis and multiple myeloma. About 30% of patients with cancer develop symptomatic spinal metastases during their illness. Prompt diagnosis and surgical treatment of these lesions, although palliative, are likely to reduce the morbidity and improve quality of life by improving ambulatory function. Study Design: Retrospective review of medical records. Objective: To evaluate postoperative functional recovery and the epidemiological profile of neoplastic spinal cord compression in two neurosurgical centers in southern Brazil. Methods: We retrospectively analyzed the data of all patients who underwent palliative surgery for symptomatic neoplastic spine lesion from metastatic cancer, in two neurosurgical centers, between January 2003 and July 2021. The variables age, sex, neurological status, histological type, affected segment, complications and length of hospitalization were analyzed. Results: A total of 82 patients were included. The lesions occurred in the thoracic spine in 60 cases. At admission, 95% of the patients had neurological deficits, most of which were Frankel C (37%). At histopathological analysis, breast cancer was the most common primary site. After surgery, the neurological status of 46 patients (56%) was reclassified according to the Frankel scale. Of these, 22 (47%) regained ambulatory capacity. Conclusion: Surgical treatment of metastatic spinal cord compression improved neurological status and ambulatory ability in our sample. Level of evidence II; Retrospective study.

Development of the spinal cord injury pressure sore onset risk screening (SCI-PreSORS) instrument: a pressure injury risk decision tree for spinal cord injury rehabilitation

STUDY DESIGN

Psychometric study based on retrospectively collected data.

OBJECTIVE

Development of a pressure injury (PI) risk screening instrument for use during spinal cord injury (SCI) rehabilitation.

SETTING

Tertiary rehabilitation center.

METHODS

Medical charts of 807 inpatients participating in SCI rehabilitation were reviewed. Two models (recursive partitioning and logistic regression) were developed with demographic and Functional Independence Measure (FIM) variables and compared with the SCI Pressure Ulcer Scale (SCIPUS, n = 603) and Braden scale (n = 100) using modeling (n = 615) and validation (n = 192) datasets. Sensitivity and specificity analyses were completed for each model. Models yielding high sensitivity and area under the curve (AUC), while minimizing false negatives (FN < 0.5%) were preferred.

RESULTS

In the modeling dataset, a single dichotomized FIM variable, Bed/Chair Transfers <4, was predictive of PI incidence (sensitivity = 97%, AUC = 74%, FN = 0.49%) and had similar metrics as the logistic regression model (sensitivity = 97%, AUC = 76%, FN = 0.49%). The recursive partitioning model had fewer FN (sensitivity = 98%, AUC = 75%, FN = 0.33%). When applied to the validation dataset, both models performed similarly. The SCIPUS performed poorly (AUC < 70%). When analyses were limited to cases with available Braden data and no admission PI, recursive partitioning outperformed the other methods for PI risk screening.

CONCLUSION

A recursive partitioning model, named the SCI-PreSORS (SCI Pressure Sore Onset Risk Screening), demonstrated promise for PI risk screening during inpatient SCI rehabilitation. Prospective validation of the new model is warranted.

The Spinal Cord Injury Pressure Ulcer Scale (SCIPUS): an assessment of validity using Rasch analysis

STUDY DESIGN

Secondary analysis of retrospective data.

OBJECTIVE

The aim of this study was to further validate the Spinal Cord Injury Pressure Ulcer Scale (SCIPUS) using Rasch analysis.

SETTING

Two rehabilitation centers in Canada.

METHOD

Data were collected as part of the Spinal Cord Injury Knowledge Mobilization Network (SCI KMN) initiative. The SCIPUS was completed within 72 h of inpatient admission. Persons admitted for initial rehabilitation in two inpatient spinal cord rehabilitation programs were included in the project.

RESULTS

Data from 886 participants were analyzed, approximately 60% of whom were males. Rasch analyses demonstrated that the SCIPUS, in its current format did not meet criteria required for true measurement. A transformed version of the SCIPUS obtained by deletion of misfitting items and modification of the response scales improved fit to the model and showed preliminary evidence of unidimensionality. The person separation index, however indicated that the scale requires further adjustments of its scoring options.

CONCLUSIONS

In its original form, the SCIPUS does not meet the requirements of the Rasch model and its total score should be used cautiously. However, following some adjustments to the items such as addressing DIF between sites to insure a standardized assessment across sites and adding response options to some of the items, interval-scale measurement should be possible.

Determining Pressure Injury Risk on Admission to Inpatient Spinal Cord Injury Rehabilitation: A Comparison of the FIM, Spinal Cord Injury Pressure Ulcer Scale, and Braden Scale

OBJECTIVE

Assess the utility of the admission Spinal Cord Injury Pressure Ulcer Scale (SCIPUS), Braden Scale, and the FIM for identifying individuals at risk for developing pressure injury during inpatient spinal cord injury (SCI) rehabilitation.

DESIGN

Retrospective cohort.

SETTING

Two tertiary rehabilitation centers.

PARTICIPANTS

Individuals (N=754) participating in inpatient SCI rehabilitation.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Logistic regression analysis was performed to determine the utility of the SCIPUS, Braden Scale, and FIM for identifying individuals at risk for developing pressure injury (PI) during inpatient SCI rehabilitation. Sensitivity, specificity, positive predictive value, negative predictive value, false negative rate, odds ratio, likelihood ratio, and area under the curve (AUC) are reported.

RESULTS

The SCIPUS total score and its individual items did not demonstrate acceptable accuracy (AUC≥0.7) whereas the Braden Scale (0.73) and the FIM score (0.74) did. Once items were dichotomized into high and low risk categories, 1 Braden item (friction and shear), 5 FIM items (bathing, toileting, bed/chair transfer, tub/shower transfer, toilet transfer), the FIM transfers subscale, FIM Motor subscale, and the FIM instrument as a whole, maintained AUCs ≥0.7 and negative predictive values ≥0.95. The FIM bed/chair transfer score demonstrated the highest likelihood ratio (2.62) and overall was the most promising measure for determining PI risk.

CONCLUSION

Study findings suggest that a simple measure of mobility, admission FIM bed/chair transfer score of 1 (total assist), can identify at-risk individuals with greater accuracy than both an SCI specific instrument (SCIPUS) and a PI specific instrument (Braden). The FIM bed/chair transfer score can be readily determined at rehabilitation admission with minimal administrative and clinical burden.

Protocol for a scoping review of skin self-care of people with spinal cord injury

INTRODUCTION

In recent years, increasing methodological references have been used in scientific research; these are points of support in the search for evidence, formulation and elaboration of instruments, scales, guideline and protocols. However, significant variability currently exists in scoping review conduct and reporting, thus limiting the potential of the methodology to advance research and practice about skin self-care of people with spinal cord injury (SCI). Our objective was to perform a scoping review protocol within the health rehabilitation context of people with SCI, focusing on skin self-care.

METHODS AND ANALYSIS

The protocol was developed by using the scoping review methodological framework proposed by Arksey and O'Malley and further refined by the Joanna Briggs Institute, incorporating insights from more recent innovations in scoping review methodology. Sensitive searches of 13 electronic databases from 2007 to 2017 will be supplemented by grey literature searches. Two reviewers using a tool developed for this scoping review will screen eligible studies.

ETHICS AND DISSEMINATION

The scoping review will undertake a secondary analysis of previously collected data and does not require ethical approval; however, the ethical precepts of copyright will be respected. The results will facilitate a better understanding of the practical health rehabilitation context of people with SCI, the impacts of these rehabilitations and how to build an evidence base for this work in the future.
