Application of the Delphi method to the development of common data elements for social drivers of health: A systematic scoping review

Collaborative data science requires standardized, harmonized, interoperable, and ethically sourced data. Developing an agreed-upon set of elements requires capturing different perspectives on the importance and feasibility of the data elements through a consensus development approach. This study reports on the systematic scoping review of literature that examined the inclusion of diverse stakeholder groups and sources of social drivers of health variables in consensus-based common data element (CDE) sets. This systematic scoping review included sources from PubMed, Embase, CINAHL, WoS MEDLINE, and PsycINFO databases. Extracted data included the stakeholder groups engaged in the Delphi process, sources of CDE sets, and inclusion of social drivers data across 11 individual and 6 social domains. Of the 384 studies matching the search string, 22 were included in the final review. All studies involved experts with healthcare expertise directly relevant to the developed CDE set, and only six (27%) studies engaged health consumers. Literature reviews and expert input were the most frequent sources of CDE sets. Seven studies (32%) did not report the inclusion of any demographic variables in the CDE sets, and each demographic SDoH domain was included in at least one study with age and sex assigned at birth included in all studies, and social driver domains included only in four studies (18%). The Delphi technique engages diverse expert groups around the development of SDoH data elements. Future studies can benefit by involving health consumers as experts.

A data set for the design and implementation of the upper limb disability registry

BACKGROUND

If the data elements needed for patient registries are not identified, designing and implementing them can be very challenging. Identifying and introducing a Data Set (DS) can help solve this challenge. The aim of this study was to identify and present a DS for the design and implementation of the upper limb disability registry.

MATERIALS AND METHODS

This cross-sectional study was conducted in two phases. In the first phase, to identify the administrative and clinical data elements required for registry, a comprehensive study was conducted in PubMed, Web of Science, and Scopus databases. Then, the necessary data elements were extracted from the studies and a questionnaire was designed based on them. In the second phase, in order to confirm the DS, the questionnaire was distributed to 20 orthopedic, physical medicine and rehabilitation physicians and physiotherapists during a two-round Delphi. In order to analyze the data, the frequency and mean score of each data element were calculated. Data elements that received an agreement more than 75% in the first or two-round Delphi were considered for the final DS.

RESULTS

A total of 81 data elements in five categories of "demographic data", "clinical presentation", "past medical history", "psychological issues", and "pharmacological and non-pharmacological treatments" were extracted from the studies. Finally, 78 data elements were approved by experts as essential data elements for designing a patient registry for upper limb disabilities.

CONCLUSION

In this study, the data elements necessary for the design and implementation of the upper limb disability registry were suggested. This DS can help registry designers and health data administrators know what data needs to be included in the registry system in order to have a successful design and implementation. Moreover, this standardized DS can be effective for integrating and improving the information management of people with upper limb disabilities and used to accurately gather the upper limb disabilities data for research and policymaking purposes.

Total Knee Arthroplasty in Patients with Spinal Cord Injury: Impact on Medical Complications, Hospital Costs and Length of Stay

INTRODUCTION

Patients with spinal cord injury (SCI) with degenerative joint disease of the knee may require total knee arthroplasty (TKA). This study examines the demographic and immediate postoperative outcomes of patients with SCI who undergo TKA.

METHODS

Admissions data for TKA and SCI were analyzed from the National Inpatient Sample database using International Classification of Diseases, 10th Revision, Clinical Modification diagnosis codes. An extensive array of preoperative and postoperative variables was compared among SCI TKA patients and non-SCI TKA patients. An unmatched and matched analysis using a 1:1 propensity match algorithm was conducted to compare the two groups.

RESULTS

Patients with SCI tend to be younger and have a 7.518 times greater risk of acute renal failure, 2.3 times greater risk of blood loss, and higher risk of local complications, including periprosthetic fracture and prosthetic infection. The average length of stay in the SCI cohort was 2.12 times greater, with a 1.58 times higher mean total incurred charge than the non-SCI group.

CONCLUSION

SCI is associated with an increased risk of acute renal failure, blood loss anemia, periprosthetic fractures and infections, a longer length of stay, and greater incurred charges in TKA patients.

STUDY DESIGN

Retrospective study.

Corticospinal Motor Circuit Plasticity After Spinal Cord Injury: Harnessing Neuroplasticity to Improve Functional Outcomes

Spinal cord injury (SCI) is a devastating condition that affects approximately 294,000 people in the USA and several millions worldwide. The corticospinal motor circuitry plays a major role in controlling skilled movements and in planning and coordinating movements in mammals and can be damaged by SCI. While axonal regeneration of injured fibers over long distances is scarce in the adult CNS, substantial spontaneous neural reorganization and plasticity in the spared corticospinal motor circuitry has been shown in experimental SCI models, associated with functional recovery. Beneficially harnessing this neuroplasticity of the corticospinal motor circuitry represents a highly promising therapeutic approach for improving locomotor outcomes after SCI. Several different strategies have been used to date for this purpose including neuromodulation (spinal cord/brain stimulation strategies and brain-machine interfaces), rehabilitative training (targeting activity-dependent plasticity), stem cells and biological scaffolds, neuroregenerative/neuroprotective pharmacotherapies, and light-based therapies like photodynamic therapy (PDT) and photobiomodulation (PMBT). This review provides an overview of the spontaneous reorganization and neuroplasticity in the corticospinal motor circuitry after SCI and summarizes the various therapeutic approaches used to beneficially harness this neuroplasticity for functional recovery after SCI in preclinical animal model and clinical human patients' studies.

The data set development for the National Spinal Cord Injury Registry of Iran (NSCIR-IR): progress toward improving the quality of care

STUDY DESIGN

Descriptive study.

OBJECTIVES

The aim of this manuscript is to describe the development process of the data set for the National Spinal Cord Injury Registry of Iran (NSCIR-IR).

SETTING

SCI community in Iran.

METHODS

The NSCIR-IR data set was developed in 8 months, from March 2015 to October 2015. An expert panel of 14 members was formed. After a review of data sets of similar registries in developed countries, the selection and modification of the basic framework were performed over 16 meetings, based on the objectives and feasibility of the registry.

RESULTS

The final version of the data set was composed of 376 data elements including sociodemographic, hospital admission, injury incidence, prehospital procedures, emergency department visit, medical history, vertebral injury, spinal cord injury details, interventions, complications, and discharge data. It also includes 163 components of the International Standards for the Neurologic Classification of Spinal Cord Injury (ISNCSCI) and 65 data elements related to quality of life, pressure ulcers, pain, and spasticity.

CONCLUSION

The NSCIR-IR data set was developed in order to meet the quality improvement objectives of the registry. The process was centered around choosing the data elements assessing care provided to individuals in the acute and chronic phases of SCI in hospital settings. The International Spinal Cord Injury Data Set was selected as a basic framework, helped by comparison with data from other countries. Expert panel modifications facilitated the implementation of the registry process with the current clinical workflow in hospitals.

Scoliosis in paediatric onset spinal cord injuries

STUDY DESIGN

This is a retrospective longitudinal review.

OBJECTIVE

The purpose of this review was to identify predictors of developing clinical scoliosis and compare between traumatic and neurological aetiologies of SCI.

SETTING

This study was conducted at the Midland Centre of SCI.

METHOD

Case notes of all patients injured at an age up to 18 years and admitted between 1971 and 2013 were reviewed.

RESULTS

Sixty-nine individuals were identified, of which seven were excluded: three with pre-existing scoliosis and four with spina bifida. The remaining 62 (44 males, 18 females) had a median age at injury of 17 years (inter quartile range 13-17). Of these, 51 (82%) had traumatic and 11 (18%) had neurological injury. Most (42/51; 82%) of the children who had a traumatic injury were older than 13 years. The risk of developing scoliosis was lower for older patients (RR 0.68 per year, 95% CI 0.52-0.83) or following a traumatic injury (RR 0.36, 95% CI 0.20-0.66). A multivariable analysis based on age and trauma showed that only older age decreased the risk. A robust Receiver Operator Curve analysis suggested 14.6 years as the optimal threshold to predict development of scoliosis within 10 years (Area Under the Curve; AUC 0.83 (95% CI 0.73-0.93), sensitivity 70% (95% CI 50-89%), specificity 89% (95% CI 74-100%).

CONCLUSION

Our results suggest that age below 14.6 years was a predictor for scoliosis. Once adjustment is made for age, the incidence of scoliosis does not differ between traumatic and neurological aetiologies of paediatric SCI injury.

The International Spinal Cord Injury Pediatric Activity and Participation Basic Data Set

Study design

International focus groups.

Objectives

The objective of this project was to develop the International Spinal Cord Injury (SCI) Pediatric Activity and Participation (A&P) Basic Data Set.

Methods

A focus group of experts in pediatric and adult SCI, and contributors of the existing adult International SCI Adult A&P Basic Data Set convened to develop an initial draft of the data set, which was iteratively refined over a 12 month period based on relevant literature and existing outcome measures that evaluate pediatric activity and participation. The draft was reviewed and approved by the larger project working group and then distributed to the International Spinal Cord Society (ISCoS), American Spinal Injury Association (ASIA), and relevant expert groups for review. Feedback received was considered before the final data set was approved.

Results

The International SCI Pediatric A&P Basic Data Set is comprised of 13 variables: administration date, mobility, dressing, feeding, toileting, communication, family outings, spending time with friends, being out with friends, participating in team or club activity, paid work, dating, and physical activity. It is intended for children between 6 and 17 years of age, who have been discharged from initial rehabilitation/hospitalization for a minimum of 3 months.

Conclusion

The International SCI Pediatric A&P Basic Data Set was developed to standardize the recording of a minimal amount of information about activities and participation in children with SCI. Further work on reliability and cultural validation is needed.

Neuropathic Pain After Spinal Cord Injury: Challenges and Research Perspectives

Neuropathic pain is a debilitating consequence of spinal cord injury (SCI) that remains difficult to treat because underlying mechanisms are not yet fully understood. In part, this is due to limitations of evaluating neuropathic pain in animal models in general, and SCI rodents in particular. Though pain in patients is primarily spontaneous, with relatively few patients experiencing evoked pains, animal models of SCI pain have primarily relied upon evoked withdrawals. Greater use of operant tasks for evaluation of the affective dimension of pain in rodents is needed, but these tests have their own limitations such that additional studies of the relationship between evoked withdrawals and operant outcomes are recommended. In preclinical SCI models, enhanced reflex withdrawal or pain responses can arise from pathological changes that occur at any point along the sensory neuraxis. Use of quantitative sensory testing for identification of optimal treatment approach may yield improved identification of treatment options and clinical trial design. Additionally, a better understanding of the differences between mechanisms contributing to at- versus below-level neuropathic pain and neuropathic pain versus spasticity may shed insights into novel treatment options. Finally, the role of patient characteristics such as age and sex in pathogenesis of neuropathic SCI pain remains to be addressed.

Neuropathic pain and spasticity: intricate consequences of spinal cord injury

STUDY DESIGN

The 2016 International Spinal Cord Society Sir Ludwig Guttmann Lecture.

OBJECTIVES

The aim of this review is to identify different symptoms and signs of neuropathic pain and spasticity after spinal cord injury (SCI) and to present different methods of assessing them. The objective is to discuss how a careful characterization of different symptoms and signs, and a better translation of preclinical findings may improve our understanding of the complex and entangled mechanisms of neuropathic pain and spasticity.

METHODS

A MEDLINE search was performed using the following terms: 'pain', 'neuropathic', 'spasticity', 'spasms' and 'spinal cord injury'.

RESULTS

This review identified different domains of neuropathic pain and spasticity after SCI and methods to assess them in preclinical and clinical research. Different factors important for pain description include location, onset, pain descriptors and somatosensory function, while muscle tone, spasms, reflexes and clonus are important aspects of spasticity. Similarities and differences between neuropathic pain and spasticity are discussed.

CONCLUSIONS

Understanding that neuropathic pain and spasticity are multidimensional consequences of SCI, and a careful examination and characterization of the symptoms and signs, are a prerequisite for understanding the relationship between neuropathic pain and spasticity and the intricate underlying mechanisms.

Standardization of Data for Clinical Use and Research in Spinal Cord Injury

Increased survival after spinal cord injury (SCI) worldwide has enhanced the need for quality data that can be compared and shared between centers, countries, as well as across research studies, to better understand how best to prevent and treat SCI. Such data should be standardized and be able to be uniformly collected at any SCI center or within any SCI study. Standardization will make it possible to collect information from larger SCI populations for multi-center research studies. With this aim, the international SCI community has obtained consensus regarding the best available data and measures for use in SCI clinical practice and research. Reporting of SCI data is likewise standardized. Data elements are continuously updated and developed using an open and transparent process. There are ongoing internal, as well as external review processes, where all interested parties are encouraged to participate. The purpose of this review paper is to provide an overview of the initiatives to standardize data including the International Spinal Cord Society's International SCI Data Sets and the National Institutes of Health, National Institute of Neurological Disorders and Stroke Common Data Elements Project within SCI and discuss future opportunities.

Reliability of the International Spinal Cord Injury Musculoskeletal Basic Data Set

STUDY DESIGN

Psychometric study.

OBJECTIVES

To determine the intra- and inter-rater reliability and content validity of the International Spinal Cord Injury (SCI) Musculoskeletal Basic Data Set (ISCIMSBDS).

SETTING

Four centers with one in each of the countries in Australia, England, India and the United States of America.

METHODS

A total of 117 participants with a C2 to S1 neurological level and American Spinal Injury Association Impairment Scale A to D injury were recruited. The median (interquartile range) time since injury was 9 years (2-29). Fifty-seven participants were assessed by the same assessor, and 60 participants were assessed by two different assessors on two different occasions to determine the intra- and inter-rater reliability, respectively. Kappa statistics or crude agreement was used to measure reliability. Content validity was assessed through focus group interviews of people with SCI and health-care professionals.

RESULTS

The intra-rater reliability ranged from κ=0.62 to 1.00 and crude agreement from 75% to 100% for each of the variables on the ISCIMSBDS. The inter-rater reliability ranged from κ=-0.25 to 1.00, with a diverse crude agreement ranging from 0% to 100%. The inter-rater reliability was unsatisfactory for the following variables: 'Date of fracture', 'Fragility fractures', 'Scoliosis, method of assessment', 'Other musculoskeletal problems' and 'Do any of the above musculoskeletal challenges interfere with your activities of daily living (transfers, walking, dressing, showers, etc.)?'. Results from validity discussions implied no major suggestions for changes.

CONCLUSION

Overall, the ISCIMSBDS is reliable and valid, although 5 of the 12 variables may benefit from further refinement.

Novel mouse model of spinal cord injury-induced heterotopic ossification

Heterotopic ossification (HO) develops in about 20% to 30% of patients with spinal cord injury (SCI) and significantly impairs their rehabilitation. There is no effective prevention or treatment for this condition at this time. Our current understanding of its etiology and pathophysiology is limited partially due to the lack of clinically relevant animal models. In this study, we report a novel mouse model of SCI-induced HO by administering a subthreshold dose of bone morphogenetic protein (BMP)-2 to muscles in mice after SCI. Micro-computed tomography scanning showed that an intramuscular injection of 0.25 micrograms of BMP-2 causes significant HO in mice with SCI but not in control (sham surgery) mice. Our analysis of gene expression showed significantly increased BMP signaling in quadriceps following SCI, suggesting that BMP signaling may play a role in SCI-induced HO. Administering 0.25 micrograms of BMP-2 to the front arms of the mice with SCI also results in the development of significant HO but not in control mice. This suggests that SCI causes a systematic osteogenic effect, which is not limited to paralyzed limbs. This novel mouse model will serve as a powerful tool in exploring the molecular mechanisms of SCI-induced HO, which may lead to novel treatment for this disease.

Common data elements for spinal cord injury clinical research: a National Institute for Neurological Disorders and Stroke project

OBJECTIVES

To develop a comprehensive set of common data elements (CDEs), data definitions, case report forms and guidelines for use in spinal cord injury (SCI) clinical research, as part of the CDE project at the National Institute of Neurological Disorders and Stroke (NINDS) of the US National Institutes of Health.

SETTING

International Working Groups.

METHODS

Nine working groups composed of international experts reviewed existing CDEs and instruments, created new elements when needed and provided recommendations for SCI clinical research. The project was carried out in collaboration with and cross-referenced to development of the International Spinal Cord Society (ISCoS) International SCI Data Sets. The recommendations were compiled, subjected to internal review and posted online for external public comment. The final version was reviewed by all working groups and the NINDS CDE team before release.

RESULTS

The NINDS SCI CDEs and supporting documents are publically available on the NINDS CDE website and the ISCoS website. The CDEs span the continuum of SCI care and the full range of domains of the International Classification of Functioning, Disability and Health.

CONCLUSION

Widespread use of CDEs can facilitate SCI clinical research and trial design, data sharing and retrospective analyses. Continued international collaboration will enable consistent data collection and reporting, and will help ensure that the data elements are updated, reviewed and broadcast as additional evidence is obtained.
