[PMID: 38278372 DOI: 10.1016/j.amepre.2024.01.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 01/18/2024] [Accepted: 01/18/2024] [Indexed: 01/28/2024]
Abstract
INTRODUCTION Adults with cerebral palsy are at risk for early multimorbidity onset, but little is known about the composition of multimorbidity profiles or how these profiles present across adulthood. The objective of this study was to identify multimorbidity profiles and association with mortality among adults with cerebral palsy. METHODS This retrospective cohort study used a random 20% fee-for-service Medicare database from January 1, 2008 to December 31, 2019 from adults aged ≥18 years with cerebral palsy. Latent class analyses using 4-class models were conducted within each age cohort (young adults aged 18-39 years, middle adulthood aged 40-64 years, and older adults aged ≥65 years) to determine patterns of 30 comorbidities defined using the International Classification of Diseases, Ninth Revision codes, identified from January 1, 2008 to December 31, 2010, and their association with mortality through December 31, 2019 (up to 11 years of follow-up); statistical analysis was performed in 2023. RESULTS Three classes were relatively consistent in the composition of comorbidities across young (n=7,020), middle (n=13,554), and older (n=4,193) cohorts: (1) low morbidity (low proportion of all comorbidities) representing 50.1% (young), 41.4% (middle), and 30.9% (older) of the cohorts; (2) neurologic multimorbidity (e.g., epilepsy, intellectual disabilities) representing 26.0% (young), 26.6% (middle), and 14.7% (older) of the cohorts; and complex multimorbidity (e.g., cardiorespiratory, nutritional, musculoskeletal, neurologic) representing 26.0% (young), 26.6% (middle), and 14.7% (older) of the cohorts. The fourth class varied by young (mental health disorders), middle (hypertension), and older (hypertension and osteoarthritis) age cohorts. Compared with the low morbidity class, other classes had an increased mortality rate for each age cohort (hazard ratio range=1.34-5.58, all p<0.001). CONCLUSIONS Findings provide insight into varied multimorbidity profiles and associations with mortality across the life course for adults with cerebral palsy.

Towards functional improvement of motor disorders associated with cerebral palsy. Lancet Neurol 2023; 22:229-243.

Abstract
Cerebral palsy is a lifelong neurodevelopmental condition arising from non-progressive disorders occurring in the fetal or infant brain. Cerebral palsy has long been categorised into discrete motor types based on the predominance of spasticity, dyskinesia, or ataxia. However, these motor disorders, muscle weakness, hypotonia, and impaired selective movements should also be discriminated across the range of presentations and along the lifespan. Although cerebral palsy is permanent, function changes across the lifespan, indicating the importance of interventions to improve outcomes in motor disorders associated with the condition. Mounting evidence exists for the inclusion of several interventions, including active surveillance, adapted physical activity, and nutrition, to prevent secondary and tertiary complications. Avenues for future research include the development of evidence-based recommendations, low-cost and high-quality alternatives to existing therapies to ensure universal access, standardised cerebral palsy registers to harmonise epidemiological and clinical information, improved adult screening and check-up programmes to facilitate positive lived experiences, and phase 3 trials for new interventions.

Prevalence and incidence of chronic conditions among adults with cerebral palsy: A systematic review and meta-analysis. Dev Med Child Neurol 2023. [PMID: 36807150 DOI: 10.1111/dmcn.15526] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Revised: 12/16/2022] [Accepted: 12/21/2022] [Indexed: 02/22/2023]
Abstract
AIM To assess the prevalence and incidence of chronic conditions among adults with cerebral palsy (CP) and compare them to the prevalence and incidence among adults without CP. METHOD We searched MEDLINE and Embase for studies reporting the prevalence or incidence of one or more chronic conditions among adults with CP. Two independent reviewers screened titles, abstracts, and full-text articles. Two independent reviewers extracted data relating to prevalence and incidence and appraised study quality. We performed random-effects meta-analyses to pool prevalence and incidence. RESULTS We identified 69 studies; 65 reported the prevalence of 53 conditions and 13 reported the incidence of 21 conditions. At least 20% of adults had the following conditions: depression (21%); anxiety (21%); mood affective disorders (23%); asthma (24%); hypertension (26%); epilepsy (28%); urinary incontinence (32%); malnutrition (38%); and scoliosis (46%). Adults with CP were more likely to have type 2 diabetes, anxiety, bipolar disorder, depression, schizophrenia, hypertension, ischaemic heart disease, stroke, cerebrovascular disease, asthma, liver disease, osteoarthritis, osteoporosis, underweight, and chronic kidney disease than adults without CP. INTERPRETATION These data from 18 countries, which provide an international perspective, may be used to promote awareness, identify targets for intervention, and inform the development of appropriate supports for adults with CP.

Whitney DG. 5-year risk of “adult-onset” chronic diseases during childhood and adolescent transitioning for individuals with cerebral palsy. Prev Med Rep 2022; 29:101933. [PMID: 35928595 PMCID: PMC9344024 DOI: 10.1016/j.pmedr.2022.101933] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 07/18/2022] [Accepted: 07/26/2022] [Indexed: 12/01/2022] Open
Abstract
“Adult-onset” chronic diseases may begin in childhood for individuals with CP. 5-year disease risk was < 64.3-fold higher for < 1–13 year olds with vs without CP. 5-year chronic disease risks were elevated for CP across all developmental stages. Patient factors impacted disease risk variably for children with CP. Findings may inform when to implement prevention efforts and who is more at-risk.
Epidemiologic evidence documenting risk of chronic diseases as children with cerebral palsy age throughout growth is lacking to inform prevention strategies. The objective was to characterize the 5-year risk of chronic diseases that are typically associated with advanced aging among < 1–13 year olds with cerebral palsy and effects by patient-level factors. This retrospective cohort study used nationwide commercial administrative claims from 01/01/2001–12/31/2018 from children < 1–13 years old with ≥ 5 years of mostly continuous insurance enrollment. The 5-year risk of chronic diseases was examined for the entire cohort with and without cerebral palsy and then by baseline age group (<1–2, 3–5, 6–8, 9–11, 12–13 years old), including cardiorespiratory, metabolic, kidney, and liver diseases, cancer, depression, and osteoarthritis. For cerebral palsy, the association between 5-year chronic disease rate and patient-level factors was assessed using Cox regression. Children with (n = 5,559) vs without (n = 2.3 million) cerebral palsy had a higher 5-year risk of all chronic diseases when comparing the entire cohorts (relative risk, 1.19 to 64.26, all P < 0.05) and most chronic diseases when comparing cohorts for each age group. Among children with cerebral palsy, there were effects by gender, co-occurring intellectual disabilities and/or epilepsy, and wheelchair use for some chronic diseases, which can help to identify at-risk children. This study provides novel epidemiologic evidence of 5-year risk of “adult-onset” chronic diseases for children with cerebral palsy during important developmental stages, and associated patient-level factors (to enhance clinical detection). Findings may inform when to implement prevention strategies and who may be more at risk.

Post-Fracture Inpatient and Outpatient Physical/Occupational Therapy and Its Association with Survival among Adults with Cerebral Palsy. J Clin Med 2022; 11:jcm11195561. [PMID: 36233436 PMCID: PMC9570908 DOI: 10.3390/jcm11195561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 09/15/2022] [Accepted: 09/20/2022] [Indexed: 11/16/2022] Open
Abstract
Physical and/or occupational therapy (PT/OT) may improve post-fracture health and survival among adults with cerebral palsy (CP), but this has not been studied in the inpatient setting. The objective was to quantify the association between acute inpatient and outpatient PT/OT use with 1-year mortality among adults with CP. This was a retrospective cohort study of adults with CP with an incident fragility fracture admitted to an acute care or rehabilitation facility using a random 20% Medicare fee-for-service dataset. Acute care/rehabilitation PT/OT was measured as the average PT/OT cost/day for the length of stay (LOS). Weekly exposure to outpatient PT/OT was examined up to 6 months post-fracture. Cox regression examined the adjusted association between the interaction of acute care/rehabilitation average PT/OT cost/day and LOS with 1-year mortality. A separate Cox model added time-varying outpatient PT/OT. Of 649 adults with CP, average PT/OT cost/day was associated with lower mortality rate for LOS < 17 days (HR range = 0.78−0.93), and increased mortality rate for LOS > 27 days (HR ≥ 1.08) (all, p < 0.05). After acute care/rehabilitation, 44.5% initiated outpatient PT/OT, which was associated with lower mortality rate (HR = 0.52; 95% CI = 0.27−1.01). Post-fracture inpatient and outpatient PT/OT were associated with improved 1-year survival among adults with CP admitted to acute care/rehabilitation facilities.

Abstract
AIM This study aimed to describe the most common combinations of comorbidities and their relationship to quality of life in a sample of adults over 40 years of age with cerebral palsy. METHODS Patients who are 40 years or older and admitted to the hospital in the last 5 years and were diagnosed with cerebral palsy were included. Demographic data and comorbidities were both questioned through the Patient Information Management System and confirmed by asking the individual about their diseases. The patients' quality of life was evaluated with the EQ-5D-3L Telephone interview version. Principal component analysis was used to determine comorbidity combinations for multiple morbidity. RESULTS Comorbidity was found in 72.1% of the participants and multimorbidity was found in 47.5%. The 5 most common comorbidities were musculoskeletal diseases (34.4%), psychiatric diseases (21.3%), essential hypertension (21.3%), osteoporosis (18%) and hyperlipidemia (18%). As a result of principal component analysis, a total of five components are formed and this most common comorbidity combinations in the sample explained 66.78% of the total variance. CONCLUSIONS New combinations of comorbidities have been demonstrated that may perhaps serve as a starting point for identifying new association of pathways. Future efforts are needed to identify modifiable factors for early intervention and prevention of chronic health problems in this population.
