Adults with myelomeningocele and other forms of spinal dysraphism: hospital care in the United States since the turn of the millennium

Long-term mortality outcomes and mortality predictors in patients with myelomeningocele

OBJECTIVE

Despite advances, myelomeningocele remains a major cause of mortality and disability. This study aims to analyze factors influencing mortality and suggest ways to reduce it.

METHODS

We reviewed 173 patients who underwent surgery for myelomeningocele from January 2010 to December 2021. Variables affecting mortality were categorized into patient-related and indirectly related factors. Data were collected through patient file reviews and phone interviews with parents.

RESULTS

Mortality is influenced by multiple factors: female gender (3.2-fold increase), paraplegia (3.1-fold increase), absence of tethered cord release surgery (9.4-fold increase), scoliosis (4.2-fold increase), and renal failure (5.28-fold increase). Defect size and father's education level also significantly impact mortality. The overall mortality rate was 20.8 %, with hydrocephalus being the leading cause.

CONCLUSION

Mortality and disability in myelomeningocele patients remain high, with over 50 % of deaths being preventable. Effective management could significantly improve mortality rates. Long-term studies are crucial for advancing research in this field.

Multidisciplinary management of people with spina bifida across the lifespan

The average worldwide prevalence of neural tube defects (NTDs) is 1.0 per 1000 births. Its development is multifactorial due to genetic and non-genetic factors. Spina bifida (SB) is one of main representatives of NTD. The spinal cord lesion level is the main determinant of the level of paralysis, numbness, and difficulties with bladder/bowel functions. Myelomeningocele prenatal repair reduces hydrocephalus and hindbrain herniation and improves motor function. The severity of hydrocephalus is associated with poorer neurodevelopmental outcomes whether operated on prenatally or after birth. People with SB tend to have a lower IQ and cognitive difficulties. Early diagnosis, proactivity, and lifelong multidisciplinary follow-up are key protective issues. Invasive urological interventions should be considered in selected patients after failure of conservative treatment. Transition to adult care should be well planned as it is challenging. Health literacy is directly associated with success at transition. Sexuality and fertility should be addressed before/during puberty. Overall, the rates of fecal and urinary continence and skin breakdown increase with age, whereas the ability to ambulate declines with age. Bowel and urinary incontinence are independent predictors of lower health-related quality of life (HRQoL) in adults with SB. Bowel incontinence has negative impact on HRQoL regardless of frequency or amount. Long-term caregiver support should be offered at diagnosis. Survival at a mean of 50 years is poor, at 32%, due to central nervous system deaths, cancer, urological disease, and sepsis. Challenges to implementation of recommended practices exist, especially in low and middle-income countries.

Prevented cases of neural tube defects and cost savings after folic acid fortification of flour in Brazil

Anencephaly, encephalocele, and spina bifida are congenital neural tube defects and are the main causes of neonatal morbidity and mortality and impose a heavy economic burden on health systems. This study to estimates the direct costs of neural tube defects from the perspective of the Brazilian Ministry of Health, and the prevented cases and cost savings during the period in which mandatory folic acid fortification was in effect in the country (2010-2019). It is a top-down cost-of-illness oriented study based on the prevalence of the disorders in Brazil. Data were collected from the Brazilian Ministry of Health's outpatient and hospital information system databases. The direct cost was estimated from the total patient-years, allocated by age and type of disorder. Prevented cases and cost savings were determined by the difference in the prevalence of the disorders in the pre- and post-fortification periods based on the total number of births and the sum of outpatient and hospital costs during the period. The total cost of outpatient and hospital services for these disorders totaled R$ 92,530,810.63 (Int$ 40,565,896.81) in 10 years; spina bifida accounted for 84.92% of the total cost. Hospital costs were expressive of all three disorders in the first year of the patient's life. Between 2010 and 2019, mandatory folic acid fortification prevented 3,499 live births with neural tube defects and resulted in R$ 20,381,586.40 (Int$ 8,935,373.25) in hospital and outpatient cost savings. Flour fortification has proved to be a valuable strategy in preventing pregnancies with neural tube defects. Since its implementation, there has been a 30% decrease in the prevalence of neural tube defects and a 22.81% decrease associated in hospital and outpatient costs.

Estimating the prevalence of neurosurgical interventions in adults with spina bifida using the Health Facts data set: implications for transition planning and the development of adult clinics

OBJECTIVE

As the care of patients with spina bifida continues to evolve, life expectancy is increasing, leading to a critical need for transition planning from pediatric-based to adult-based care. The burden of neurosurgical care for adults with spina bifida remains unknown. In this study, the authors sought to use a large national data set to estimate the prevalence of neurosurgical interventions in adults with spina bifida.

METHODS

This study utilized Health Facts, which is a de-identified proprietary data set abstracted from all Cerner electronic health records. It includes 69 million unique patients with > 500 million encounters in 580 centers. Validation, technical exclusions, and data filters were applied to obtain an appropriate cohort of patients. The ICD-9 and ICD-10 codes for all types of spinal dysraphism, as well as the Current Procedural Terminology (CPT) codes for hydrocephalus procedures, spinal cord untethering, and Chiari decompression, were queried and records were retrieved. Demographic variables along with differences in age groups and temporal trends were analyzed.

RESULTS

Overall, 24,764 unique patients with ≥ 1 encounter with a spinal dysraphism diagnosis between 2000 and 2017 were identified. The pediatric cohort included 11,123 patients with 60,027 separate encounters, and the adult cohort included 13,641 patients with 41,618 separate encounters. The proportion of females was higher in the adult (62.9%) than in the pediatric (51.4%) cohort. Annual encounters were stable from 2 to 18 years of age, but then decreased by approximately half with a precipitous drop after age 21 years. The sex distribution of adults and children who underwent procedures was similar (54.6% female adults vs 52.4% female children). Surgical interventions in adults were common. Between 2013 and 2017, there were 4913 procedures for hydrocephalus, with 2435 (49.6%) adult patients. Similarly, 273 (33.3%) of the 819 tethered cord procedures were performed in adults, as were 307 (32.9%) of 933 Chiari decompressions.

CONCLUSIONS

The Health Facts database offered another option for studying care delivery and utilization in patients aging with spina bifida. The median age of this population has now reached early adulthood, and a significant number of neurosurgical procedures were performed in adults. An abrupt drop in the rate of encounters occurred at 21 years of age, possibly reflecting transition issues such as access-to-care problems and lack of coordinated care.

Quality of life in a 61-year-old paraplegic patient with myelomeningocele: illustrative case

BACKGROUND

Limited data exist on survival of patients with myelomeningocele (MM) into late adulthood. Patients born prior to 1975 received less surgical treatment and demonstrated poorer survival. Patients born after 1975 show lower mortality rates because of advancements in prenatal care, diagnostics, technology, and treatment. The increasing number of adult patients with MM demonstrates these successes but also highlights the need for a better understanding of both medical management and quality-of-life issues in this population.

OBSERVATIONS

A 61-year-old woman presented to the hospital with a functional level T12, vertebral level low lumbar MM that had developed a tissue defect with a cerebrospinal fluid leak. The patient had her MM closed at birth and since then had received no additional surgical treatment or repair of her MM defect. After successful treatment, the patient continues to follow up for additional decompression procedures and admits to a good quality of life.

LESSONS

This case adds to the limited literature describing management of patients with MM over the age of 60. The patient’s self-described good quality of life and longevity align with reports of importance of independence, level of education, bowel management, ability to provide self-care, strong interpersonal relationships, and absence of shunted hydrocephalus.

Health promotion and preventive health care service guidelines for the care of people with spina bifida

Individuals with Spina Bifida (SB) have unique lifelong medical and social needs. Thus, when considering how to promote health and offer preventive care, providers must adapt general healthcare screening and counseling recommendations to their patients' physical and cognitive impairments along with discerning how to monitor secondary or chronic conditions common to the population. This article provides an update on the health promotion and preventive health care guidelines developed as part of the Spina Bifida Association's fourth edition of the Guidelines for the Care of People with Spina Bifida. The guidelines highlight accommodations needed to promote general preventive health, common secondary/chronic conditions such as obesity, metabolic syndrome, hypertension, musculoskeletal pain, and considerations for preventing acute care utilization for the SB population throughout the lifespan. Further research is needed to understand the effectiveness of preventive care interventions in promoting positive health outcomes and mitigating potentially preventable acute care utilization.

A Transforaminal Endoscopic Surgical Technique for Treating Lumbar Disc Herniation in the Setting of Spina Bifida

Recent literature suggests that adult patients with spina bifida receive surgery for degenerative disc disease at higher rates than the general population. However, sometimes the complex anatomic features of co-occurring spina bifida and lumbar disc herniation can significantly challenge standard surgical techniques. Here, the technical steps are presented for treating a foraminal lumbar 4-5-disc herniation in the setting of a patient with multifaceted degenerative and spina bifida occulta anatomy. Utilized is a minimally invasive approach that does not require general anesthesia or fusion and allows the patient to leave the same day. To the best of our knowledge, this is the first-reported case of endoscopic surgical decompression of a lumbar disc in a patient with spina bifida.

Giant Symptomatic Meningocele as a Delayed, Adult Complication of Lipomyelomeningocele

BACKGROUND

An expanding cohort of patients with spina bifida live well into adulthood and pose complex management challenges due to unique combinations of adult health issues overlying congenital problems.

CASE DESCRIPTION

We present a case of a 45-year-old woman with an expanding, disfiguring, painful lumbar meningocele more than 40 years after her only surgery as a 3-year-old child. A team of pediatric and adult neurosurgeons as well as plastic/reconstructive surgeons successfully performed surgery to obliterate the meningocele, with preservation of her baseline functional status, and no evidence of recurrence after more than 1 year of follow-up.

CONCLUSIONS

Symptomatic meningocele may present in a long-delayed fashion in adult patients with a history of spina bifida. Surgical treatment may provide symptomatic benefit.

Hospital Readmission of Adolescents and Young Adults With Complex Chronic Disease

IMPORTANCE

Adolescents and young adults (AYA) who have complex chronic disease (CCD) are a growing population that requires hospitalization to treat severe, acute health problems. These patients may have increased risk of readmission as demands on their self-management increase and as they transfer care from pediatric to adult health care practitioners.

OBJECTIVE

To assess variation across CCDs in the likelihood of readmission for AYA with increasing age.

DESIGN, SETTING, AND PARTICIPANTS

Retrospective 1-year cross-sectional study of the 2014 Agency for Healthcare Research and Quality Nationwide Readmissions Database for all US hospitals. Participants were 215 580 hospitalized individuals aged 15 to 30 years with cystic fibrosis (n = 15 213), type 1 diabetes (n = 86 853), inflammatory bowel disease (n = 48 073), spina bifida (n = 7819), and sickle cell anemia (n = 57 622) from January 1, 2014, to December 1, 2014.

EXPOSURES

Increasing age at index admission.

MAIN OUTCOMES AND MEASURES

Unplanned 30-day hospital readmission. Readmission odds were compared by patients' ages in 2-year epochs (with age 15-16 years as the reference) using logistic regression, accounting for confounding patient characteristics and data clustering by hospital.

RESULTS

Of 215 580 participants, 115 982 (53.8%) were female; the median (interquartile range) age was 24 (20-27) years. Across CCDs, multimorbidity was common; the percentages of index hospitalizations with 4 or more coexisting conditions ranged from to 33.4% for inflammatory bowel disease to 74.2% for spina bifida. Thirty-day hospital readmission rates varied significantly across CCDs: 20.2% (cystic fibrosis), 19.8% (inflammatory bowel disease), 20.4% (spina bifida), 22.5% (type 1 diabetes), and 34.6% (sickle cell anemia). As age increased from 15 to 30 years, unadjusted, 30-day, unplanned hospital readmission rates increased significantly for all 5 CCD cohorts. In multivariable analysis, age trends in the adjusted odds of readmission varied across CCDs. For example, for AYA who had cystic fibrosis, the adjusted odds of readmission increased to 1.9 (95% CI, 1.5-2.3) by age 21 years and remained elevated through age 30 years. For AYA who had type 1 diabetes, the adjusted odds of readmission peaked at ages 23 to 24 years (odds ratio, 2.3; 95% CI, 2.1-2.6) and then declined through age 30 years.

CONCLUSIONS AND RELEVANCE

These findings suggest that hospitalized AYA who have CCDs have high rates of multimorbidity and 30-day readmission. The adjusted odds of readmission for AYA varied significantly across CCDs with increasing age. Further attention is needed to hospital discharge care, self-management, and prevention of readmission in AYA with CCD.

An Exploratory Electrical Stimulation Protocol in the Management of an Infant With Spina Bifida: A Case Report

An infant with myelomeningocele and underdevelopment of the thoracic spinal cord was treated with 2 protocols of electrical stimulation: functional electrical stimulation and transcutaneous spinal cord electrical stimulation. The protocols were incorporated into the infant’s outpatient early intervention home programs. Prior to initiation of electrical stimulation treatment at age 6 months, the infant exhibited complete loss of sensation below the level of T8 and muscular paralysis below the level of T10. The unexpected emergence of somatosensory responses and spontaneous movements in the trunk and lower extremities are described, focusing on the electrical stimulation protocols. Spinal cord electrical stimulation protocols were not previously described in the medical literature regarding the management of children with spina bifida. Both functional and spinal cord electrical stimulation protocols used with this infant proved safe and well tolerated. The experience gained over 12 months of treatment is the subject of this case report.

Neurologic Decline in an Older Patient with Repaired Myelomeningocele Complicated with Lumbar Canal Stenosis

BACKGROUND

Tethered cord syndrome is a well-known complication after myelomeningocele (MMC) repair in childhood. However, late complications in adults with a repaired MMC are not well understood. In particular, the influence of a degenerative spinal deformity on a sustained tethered cord is still unclear.

CASE DESCRIPTION

A 63-year-old man with a repaired MMC exhibited a progressive gait disturbance and numbness in both lower limbs. Magnetic resonance imaging demonstrated that the tethered spinal cord was compressed by severe canal stenosis along the entire lumbar spine. After a multi-level lumbar decompression surgery, the patient recovered to baseline neurologic status.

CONCLUSION

In adults with a repaired MMC, lumbar canal stenosis should be investigated as a possible cause of late neurologic decline. Clinical manifestations may be complicated by the coexistence of both the original and subsequent neurologic disorders. Because these additional disorders result from compressive myelopathy, early surgical decompression is indicated to avoid irreversible spinal cord dysfunction.
