Cost-Effectiveness of Operating on Traumatic Spinal Injuries in Low-Middle Income Countries: A Preliminary Report From a Major East African Referral Center

The Epidemiology of Spinal Neurosurgery in Nigeria: A Systematic Review and Patient-Level Analysis

OBJECTIVE

Spinal pathologies are prevalent in Nigeria, though epidemiological data remains sparse. This systematic review used pooled patient-level data from across the country to generate a standardized epidemiological reference.

METHODS

Four research databases and gray literature sources were searched. Risk of bias assessment was conducted using Risk of Bias in Non-Randomised Studies - of Interventions and Cochrane's risk of bias tool. We descriptively analyzed all article metrics and statistically analyzed relevant data variables via paired t-test and χ2 independence tests (α = 0.05).

RESULTS

One hundred twenty-seven articles, comprising a patient cohort of 8425 patients, were analyzed. Most were retrospective cohort studies (46.5%) and case reports/series (31.5%), with an overall moderate-high risk of bias. Most studies were published in the last 20 years. Most patients were male (∼2.5 males per female), with an average age of 43.2 years (±16.4). Clinical diagnoses spanned the breadth of spinal neurosurgery. Approximately 45.0% of patients had complete spinal impairment. Pain (41.7%) was the most reported presenting feature. X-ray (45.1%) was the most common investigation used. Intervertebral disc herniation (18.9%) was the most prevalent imaging finding on MRI. Most patients were managed nonoperatively (57.8%), with a favorable outcome in 27.4% of patients. Posttreatment complications included pressure sores, infection, and motor deficits.

CONCLUSIONS

This systematic review and pooled analysis provide an epidemiological overview of spinal neurosurgery in Nigeria over the last 60 years and serves as a useful reference to direct future global research in this arena.

Global Neurosurgery Advances From Trenches to Bedside: Lessons From Neurosurgical Care in War, Humanitarian Assistance, and Disaster Response

INTRODUCTION

War has influenced the evolution of global neurosurgery throughout the past century. Armed conflict and mass casualty disasters (MCDs), including Humanitarian Assistance Disaster Relief missions, require military surgeons to innovate to meet extreme demands. However, the military medical apparatus is seldom integrated into the civilian health care sector. Neurosurgeons serving in the military have provided a pragmatic template for global neurosurgeons to emulate in humanitarian disaster responses. In this paper, we explore how wars and MCD have influenced innovations of growing interest in the resource-limited settings of global neurosurgery.

METHODS

We performed a narrative review of the literature examining the influence of wars and MCD on contemporary global neurosurgery practices.

RESULTS

Wartime innovations that influenced global neurosurgery include the development of triage systems and modernization with airlifts, the implementation of ambulance corps, early operation on cranial injuries in hospital camps near the battlefield, the use of combat body armor, and the rise of damage control neurosurgery. In addition to promoting task-shifting and task-sharing, workforce shortages during wars and disasters contributed to the establishment of the physician assistant/physician associate profession in the USA. Low- and middle-income countries (LMICs) face similar challenges in developing trauma systems and obtaining advanced technology, including neurosurgical equipment like battery-powered computed tomography scanners. These challenges-ubiquitous in low-resource settings-have underpinned innovations in triage and wound care, rapid evacuation to tertiary care centers, and minimizing infection risk.

CONCLUSION

War and MCDs have catalyzed significant advancements in neurosurgical care both in the pre-hospital and inpatient settings. Most of these innovations originated in the military and subsequently spread to the civilian sector as military neurosurgeons and reservist civilian neurosurgeons returned from the battlefront or other low-resource locations. Military neurosurgeons have utilized their experience in low-resource settings to make volunteer global neurosurgery efforts in LMICs successful. LMICs have, by necessity, responded to challenges arising from resource shortages by developing innovative, context-specific care paradigms and technologies.

Regulation, approval, and access of spinal implants in low-middle-income countries: a narrative review and case study

INTRODUCTION

Spinal implants play a vital role in healthcare delivery, and regulations are necessary to ensure their quality, approval, access, and use. In this article, we examine the current state of regulation and approval procedures for medical devices in low- and middle-income countries (LMICs), emphasizing the situation in Tanzania.

AREAS COVERED

We conducted a systematic literature search and interviewed a local spine implant representative to investigate the approval, availability, and access of surgical and spinal implants in LMICs, particularly in Africa. Out of the 18 included articles, six referred to African regulations, with no mention of spinal implants. Our analysis revealed that LMICs face challenges in accessing implants due to affordability, poor supply chain, and lack of expertise for their application. However, surgeons have found alternative solutions, such as using lower-cost implants from Turkish manufacturers. The Tanzania Medical Devices and Drugs Authority oversees the local regulatory and approval process for implants.

EXPERT OPINION

Regulation and accessibility of spinal implants in LMICs, particularly in Africa, are limited and negatively impact patient care and best medical practice. Potential solutions include capacity building within and collaboration among regulatory organizations to improve regulatory processes and allocating financial resources to qualitative and quantitative implant access.

Methodology of economic evaluations in spine surgery: a systematic review and qualitative assessment

OBJECTIVES

The present study is a systematic review conducted as part of a methodological approach to develop evidence-based recommendations for economic evaluations in spine surgery. The aim of this systematic review is to evaluate the methodology and quality of currently available clinical cost-effectiveness studies in spine surgery.

STUDY DESIGN

Systematic literature review.

DATA SOURCES

PubMed, Web of Science, Embase, Cochrane, Cumulative Index to Nursing and Allied Health Literature, EconLit and The National Institute for Health Research Economic Evaluation Database were searched through 8 December 2022.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Studies were included if they met all of the following eligibility criteria: (1) spine surgery, (2) the study cost-effectiveness and (3) clinical study. Model-based studies were excluded.

DATA EXTRACTION AND SYNTHESIS

The following data items were extracted and evaluated: pathology, number of participants, intervention(s), year, country, study design, time horizon, comparator(s), utility measurement, effectivity measurement, costs measured, perspective, main result and study quality.

RESULTS

130 economic evaluations were included. Seventy-four of these studies were retrospective studies. The majority of the studies had a time horizon shorter than 2 years. Utility measures varied between the EuroQol 5 dimensions and variations of the Short-Form Health Survey. Effect measures varied widely between Visual Analogue Scale for pain, Neck Disability Index, Oswestry Disability Index, reoperation rates and adverse events. All studies included direct costs from a healthcare perspective. Indirect costs were included in 47 studies. Total Consensus Health Economic Criteria scores ranged from 2 to 18, with a mean score of 12.0 over all 130 studies.

CONCLUSIONS

The comparability of economic evaluations in spine surgery is extremely low due to different study designs, follow-up duration and outcome measurements such as utility, effectiveness and costs. This illustrates the need for uniformity in conducting and reporting economic evaluations in spine surgery.

Predictors of spinal trauma care and outcomes in a resource-constrained environment: a decision tree analysis of spinal trauma surgery and outcomes in Tanzania

OBJECTIVE

The burden of spinal trauma in low- and middle-income countries (LMICs) is immense, and its management is made complex in such resource-restricted settings. Algorithmic evidence-based management is cost-prohibitive, especially with respect to spinal implants, while perioperative care is work-intensive, making overall care dependent on multiple constraints. The objective of this study was to identify determinants of decision-making for surgical intervention, improvement in function, and in-hospital mortality among patients experiencing acute spinal trauma in resource-constrained settings.

METHODS

This study was a retrospective analysis of prospectively collected data in a cohort of patients with spinal trauma admitted to a tertiary referral hospital center in Dar es Salam, Tanzania. Data on demographic, clinical, and treatment characteristics were collected as part of a quality improvement neurotrauma registry. Outcome measures were surgical intervention, American Spinal Injury Association (ASIA) Impairment Scale (AIS) grade improvement, and in-hospital mortality, based on existing treatment protocols. Univariate analyses of demographic and clinical characteristics were performed for each outcome of interest. Using the variables associated with each outcome, a machine learning algorithm-based regression nonparametric decision tree model utilizing a bootstrapping method was created and the accuracy of the three models was estimated.

RESULTS

Two hundred eighty-four consecutively admitted patients with acute spinal trauma were included over a period of 33 months. The median age was 34 (IQR 26-43) years, 83.8% were male, and 50.7% had experienced injury in a motor vehicle accident. The median time to hospital admission after injury was 2 (IQR 1-6) days; surgery was performed after a further median delay of 22 (IQR 13-39) days. Cervical spine injury comprised 38.4% of the injuries. Admission AIS grades were A in 48.9%, B in 16.2%, C in 8.5%, D in 9.5%, and E in 16.6%. Nearly half (45.1%) of the patients underwent surgery, 12% had at least one functional improvement in AIS grade, and 11.6% died in the hospital. Determinants of surgical intervention were age ≤ 30 years, spinal injury level, admission AIS grade, delay in arrival to the referral hospital, undergoing MRI, and type of insurance; admission AIS grade, delay to arrival to the hospital, and injury level for functional improvement; and delay to arrival, injury level, delay to surgery, and admission AIS grade for in-hospital mortality. The best accuracies for the decision tree models were 0.62, 0.34, and 0.93 for surgery, AIS grade improvement, and in-hospital mortality, respectively.

CONCLUSIONS

Operative intervention and functional improvement after acute spinal trauma in this tertiary referral hospital in an LMIC environment were low and inconsistent, which suggests that nonclinical factors exist within complex resource-driven decision-making frameworks. These nonclinical factors are highlighted by the authors' results showing clinical outcomes and in-hospital mortality were determined by natural history, as evidenced by the highest accuracy of the model predicting in-hospital mortality.

Delays in Presentation After Traumatic Spinal Cord Injury-A Systematic Review

BACKGROUND

Prompt surgical decompression after traumatic spinal cord injury (TSCI) may be associated with improved sensorimotor outcomes. Delays in presentation may prevent timely decompression after TSCI.

OBJECTIVE

To systematically review existing studies investigating delays in presentation after TSCI in low- and middle-income countries (LMICs) and high-income countries (HICs).

METHODS

A systematic review was conducted and studies featuring quantitative or qualitative data on prehospital delays in TSCI presentation were included. Studies lacking quantitative or qualitative data on prehospital delays in TSCI presentation, case reports or series with <5 patients, review articles, or animal studies were excluded from our analysis.

RESULTS

After exclusion criteria were applied, 24 studies were retained, most of which were retrospective. Eleven studies were from LMICs and 13 were from HICs. Patients with TSCI in LMICs were younger than those in HICs, and most patients were male in both groups. A greater proportion of patients with TSCI in studies from LMICs presented >24 hours after injury (HIC average proportion, 12.0%; LMIC average proportion, 49.9%; P = 0.01). Financial barriers, lack of patient awareness and education, and prehospital transportation barriers were more often cited as reasons for delays in LMICs than in HICs, with prehospital transportation barriers cited as a reason for delay by every LMIC study included in this review.

CONCLUSIONS

Disparities in prehospital infrastructure between HICs and LMICs subject more patients in LMICs to increased delays in presentation to care.

Secondary damage management of acute traumatic spinal cord injury in low and middle-income countries: A survey on a global scale (Part III)

•In LMICs, several factor may affect the applicability of guidelines for secondary damage control of spinal cord injury.•In LMICs, the use of steroids for spinal cord injury is heterogeneous and admissions to an intensive care units are limited.•The delays for surgical decompression of spinal cord injury can be significan and vary across income and geographic region.•Transfer times seem to be the most common reason for surgical delay in all income and geographic regions.•Costs for surgery for spinal trauma may be a significant barrier to guideline adherence, especially in low-resource settings.

Time to Surgery in Spinal Trauma: A Meta-Analysis of the World's Literature Comparing High-Income Countries to Low-Middle Income Countries

OBJECTIVE

We conducted a systematic review and meta-analysis to: 1) compare time from traumatic spinal injury (TSI) to operating room (OR) in high-income countries (HICs) versus low-middle-income countries (LMICs), and 2) evaluate hospital length of stay (LOS) in HICs versus LMICs.

METHODS

A systematic literature search was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines involving articles of all languages.

INCLUSION CRITERIA

published between 1991 and 2021, spine trauma population, single country/region, and recorded time from injury to OR. The primary outcome was time from injury to OR, and the secondary outcome was LOS. Means and standard deviations were estimated in a random effects model by DerSimonian and Laird methods.

RESULTS

Of 2367 articles, 163 met the inclusion criteria for systematic review. Regarding time from injury to OR, 23 articles were eligible for meta-analysis; 16 studies were conducted in HICs and 7 in LMICs, comprising 3819 patients with TSI. A significantly shorter mean time from injury to OR was found in HICs (1.92 days, 95% confidence interval 1.44-2.41) compared with LMICs (3.27 days, 95% confidence interval 2.27-4.27) (P = 0.020). Regarding length of stay, 14 articles were eligible for meta-analysis, 10 studies were conducted in HICs and 4 in LMICs, comprising 11,003 patients. There was no difference in LOS between HICs and LMICs (25.76 days vs. 20.48 days, P = 0.140).

CONCLUSIONS

Patients with traumatic spinal injuries in HICs were more likely to undergo earlier surgery compared to patients in LMICs. No difference was found in total LOS between HICs and LMICs. While multiple factors can influence time to surgery, these findings draw attention to the global disparity in spinal trauma care.

Direct Cost of Illness for Spinal Cord Injury: A Systematic Review

STUDY DESIGN

Systematic review.

OBJECTIVE

Providing a comprehensive review of spinal cord injury cost of illness studies to assist health-service planning.

METHODS

We conducted a systematic review of the literature published from Jan. 1990 to Nov. 2020 via Pubmed, EMBASE, and NHS Economic Evaluation Database. Our primary outcomes were overall direct health care costs of SCI during acute care, inpatient rehabilitation, within the first year post-injury, and in the ensuing years.

RESULTS

Through a 2-phase screening process by independent reviewers, 30 articles out of 6177 identified citations were included. Cost of care varied widely with the mean cost of acute care ranging from $290 to $612,590; inpatient rehabilitation from $19,360 to $443,040; the first year after injury from $32,240 to $1,156,400; and the ensuing years from $4,490 to $251,450. Variations in reported costs were primarily due to neurological level of injury, study location, methodological heterogeneities, cost definitions, study populations, and timeframes. A cervical level of the injury, ASIA grade A and B, concomitant injuries, and in-hospital complications were associated with the greatest incremental effect in cost burden.

CONCLUSION

The economic burden of SCI is generally high and cost figures are broadly higher for developed countries. As studies were only available in few countries, the generalizability of the cost estimates to a regional or global level is only limited to countries with similar economic status and health systems. Further investigations with standardized methodologies are required to fill the knowledge gaps in the healthcare economics of SCI.

SPINE20 recommendations 2021: spine care for people's health and prosperity

Purpose

The focus of SPINE20 is to develop evidence-based policy recommendations for the G20 countries to work with governments to reduce the burden of spine disease, and disability.

Methods

On September 17–18, 2021, SPINE20 held its annual meeting in Rome, Italy. Prior to the meeting, the SPINE20 created six proposed recommendations. These recommendations were uploaded to the SPINE20 website 10 days before the meeting and opened to the public for comments. The recommendations were discussed at the meeting allowing the participants to object and provide comments.

Results

In total, 27 societies endorsed the following recommendations. SPINE20 calls upon the G20 countries: (1) to expand telehealth for the access to spine care, especially in light of the current situation with COVID-19. (2) To adopt value-based interprofessional spine care as an approach to improve patient outcomes and reduce disability. (3) To facilitate access and invest in the development of a competent rehabilitation workforce to reduce the burden of disability related to spine disorders. (4) To adopt a strategy to promote daily physical activity and exercises among the elderly population to maintain an active and independent life with a healthy spine, particularly after COVID-19 pandemic. (5) To engage in capacity building with emerging countries and underserved communities for the benefit of spine patients. (6) To promote strategies to transfer evidence-based advances into patient benefit through effective implementation processes.

Conclusions

SPINE20’s initiatives will make governments and decision makers aware of efforts to reduce needless suffering from disabling spine pain through education that can be instituted across the globe.
