Traumatic Cervical Spinal Cord Injury and Income and Employment Status.

Importance: Spinal cord injury (SCI) causes drastic changes to an individual's physical health that may be associated with the ability to work. Objective: To estimate the association of SCI with individual earnings and employment status using national administrative health databases linked to income tax data. Design, Setting, and Participants: This was a retrospective, national, population-based cohort study of adults who were hospitalized with cervical SCI in Canada between January 2005 and December 2017. All acute care hospitalizations for SCI of adults ages 18 to 64 years were included. A comparison group was constructed by sampling from individuals in the injured cohort. Fiscal information from their preinjury years was used for comparison. The injured cohort was matched with the comparison group based on age, sex, marital status, province of residence, self-employment status, earnings, and employment status in the year prior to injury. Data were analyzed from August 2022 to January 2023. Main outcomes and Measures: The first outcome was the change in individual annual earnings up to 5 years after injury. The change in mean yearly earnings was assessed using a linear mixed-effects differences-in-differences regression. Income values are reported in 2022 Canadian dollars (CAD $1.00 = US $0.73). The second outcome was the change in employment status up to 5 years after injury. A multivariable probit regression model was used to compare proportions of individuals employed among those who had experienced SCI and the paired comparison group of participants. Results: A total of 1630 patients with SCI (mean [SD] age, 47 [13] years; 1304 male [80.0%]) were matched to patients in a preinjury comparison group (resampled from the same 1630 patients in the SCI group). The mean (SD) of preinjury wage earnings was CAD $46 000 ($48 252). The annual decline in individual earnings was CAD $20 275 (95% CI, -$24 455 to -$16 095) in the first year after injury and CAD $20 348 (95% CI, -$24 710 to -$15 985) in the fifth year after injury. At 5 years after injury, 52% of individuals who had an injury were working compared with 79% individuals in the preinjury comparison group. SCI survivors had a decrease in employment of 17.1 percentage points (95% CI, 14.5 to 19.7 percentage points) in the first year after injury and 17.8 percentage points (14.5 to 21.1 percentage points) in the fifth year after injury. Conclusions and Relevance: In this study, SCI was associated with a decline in earnings and employment up to 5 years after injury for adults aged 18 to 64 years in Canada.

Does hospital competition improve the quality of outpatient care? - empirical evidence from a quasi-experiment in a Chinese city.

BACKGROUND: Although countries worldwide have launched a series of pro-competition reforms, the literature on the impacts of hospital competition has produced a complex and contradictory picture. This study examined whether hospital competition contributed to an increase in the quality of outpatient care. METHODS: The dataset comprises encounter data on 406,664 outpatients with influenza between 2015 and 2019 in China. Competition was measured using the Herfindahl-Hirschman index (HHI). Whether patients had 14-day follow-up encounter for influenza at any healthcare facility, outpatient facility, and hospital outpatient department were the three quality outcomes assessed. Binary regression models with crossed random intercepts were constructed to estimate the impacts of the HHI on the quality of outpatient care. The intensity of nighttime lights was employed as an instrumental variable to address the endogenous relationship between the HHI and the quality of outpatient care. RESULTS: We demonstrated that an increase in the degree of hospital competition was associated with improved quality of outpatient care. For each 1% increase in the degree of hospital competition, an individual's risk of having a 14-day follow-up encounter for influenza at any healthcare facility, outpatient facility, and hospital outpatient department fell by 34.9%, 18.3%, and 20.8%, respectively. The impacts of hospital competition on improving the quality of outpatient care were more substantial among females, individuals who used the Urban and Rural Residents Basic Medical Insurance to pay for their medical costs, individuals who visited accredited hospitals, and adults aged 25 to 64 years when compared with their counterparts. CONCLUSION: This study demonstrated that hospital competition contributed to better quality of outpatient care under a regime with a regulated ceiling price. Competition is suggested to be promoted in the outpatient care market where hospitals have control over quality and government sets a limit on the prices that hospitals may charge.

What motivates individuals to share information with governments when adopting health technologies during the COVID-19 pandemic?

BACKGROUND: While digital governance has been adopted by governments around the world to assist in the management of the COVID-19 pandemic, the effectiveness of its implementation relies on the collection and use of personal information. This study examines the willingness of individuals to engage in information-sharing with governments when adopting health technologies during the COVID-19 pandemic. METHODS: Data were obtained from a cross-sectional survey of 4,800 individuals drawn from 16 cities in China in 2021. Tobit regression models were used to assess the impacts of an array of determinants on an individual's willingness to share information with governments when adopting health technologies. RESULTS: Individuals who perceived a higher level of helpfulness, risk, expectations from others, weariness toward privacy issues, and were sensitive to positive outcomes were more willing to share information with governments when adopting health technologies during the COVID-19 pandemic. Across all the subgroups, self-efficacy only reduced the willingness to share information with governments for individuals who spent more than seven hours per day online. The negative impacts of being sensitive to negative outcomes on the willingness to share information were only found among females and the less educated group. CONCLUSIONS: This study revealed the seemingly paradoxical behavior of individuals who perceived high risks of sharing information and a sense of fatigue toward privacy issues yet continued to be willing to share their information with their governments when adopting health technologies during the COVID-19 pandemic. This work highlighted significant differential motivations for sharing information with governments when using health technologies during a pandemic. Tailored policies that resonate with population sub-groups were suggested to be proposed to facilitate crisis management in future situations.

Association Between Online Health Information-Seeking Behaviors by Caregivers and Delays in Pediatric Cancer: Mixed Methods Study in China.

BACKGROUND: Pediatric cancer patients in China often present at an advanced stage of disease resulting in lower survival and poorer health outcomes. One factor hypothesized to contribute to delays in pediatric cancer has been the online health information-seeking (OHIS) behaviors by caregivers. OBJECTIVE: This study aims to examine the association between OHIS behaviors by caregivers and delays for Chinese pediatric cancer patients using a mixed methods approach. METHODS: This study used a mixed methods approach, specifically a sequential explanatory design. OHIS behavior by the caregiver was defined as the way caregivers access information relevant to their children's health via the Internet. Delays in pediatric cancer were defined as any one of the following 3 types of delay: patient delay, diagnosis delay, or treatment delay. The quantitative analysis methods included descriptive analyses, Student t tests, Pearson chi-square test, and binary logistic regression analysis, all performed using Stata. The qualitative analysis methods included conceptual content analysis and the Colaizzi method. RESULTS: A total of 303 pediatric cancer patient-caregiver dyads was included in the quantitative survey, and 29 caregivers completed the qualitative interview. Quantitative analysis results revealed that nearly one-half (151/303, 49.8%) of patients experienced delays in pediatric cancer, and the primary type of delay was diagnosis delay (113/303, 37.3%), followed by patient delay (50/303, 16.5%) and treatment delay (24/303, 7.9%). In this study, 232 of the 303 (76.6%) caregiver participants demonstrated OHIS behaviors. When those engaged in OHIS behaviors were compared with their counterparts, the likelihood of patient delay more than doubled (odds ratio=2.21; 95% CI 1.03-4.75). Qualitative analysis results showed that caregivers' OHIS behaviors impacted the cancer care pathway by influencing caregivers' symptom appraisal before the first medical contact and caregivers' acceptance of health care providers' diagnostic and treatment decisions. CONCLUSIONS: Our findings suggest that OHIS among Chinese pediatric caregivers may be a risk factor for increasing the likelihood of patient delay. Our government and society should make a concerted effort to regulate online health information and improve its quality. Specialized freemium consultations provided by health care providers via online health informatic platforms are needed to shorten the time for caregivers' cancer symptom appraisal before the first medical contact.

A cost-utility analysis of thrombopoietin receptor agonists for treating pediatric immune thrombocytopenia purpura after failure of first-line therapies.

BACKGROUND: Thrombopoietin receptor agonists (TPO-RAs) have emerged as a recommended treatment for children with persistent and/or chronic immune thrombocytopenic purpura (ITP). The purpose of this study was to evaluate the cost-effectiveness of TPO-RAs relative to treatment without TPO-RAs (non-TPO-RAs/usual care) for ITP in children who do not respond to first-line therapy and in whom splenectomy is not recommended in Ontario, Canada, from a hospital payer perspective. PROCEDURE: A 2-year Markov model with an embedded decision tree was used. Data on medications used, dose, response rate, bleeding, and emergency treatment events were collected from the Hospital for Sick Children in Toronto. The health outcomes were described in quality-adjusted life-years (QALYs). Health-state utilities were derived from the peer-reviewed literature. Scenario analyses, deterministic, and probabilistic sensitivity analyses were conducted. Economic costs were measured in 2021 Canadian dollars ($1.00 = US$0.80) RESULTS: TPO-RAs are estimated to result in an increased cost of $27,118 and a QALY gain of 0.21 compared to non-TPO-RAs over a 2-year horizon, resulting in an incremental cost-effectiveness ratio (ICER) of $129,133. In a 5-year scenario analysis, the ICER fell to $76,403. In the probabilistic sensitivity analysis, TPO-RAs exhibit a 40.0% probability of being cost-effective at a conventional ($100,000) willingness-to-pay threshold per QALY gained. CONCLUSIONS: Further assessment of the long-term efficacy of TPO-RAs is warranted to obtain more precise long-term estimates. As the costs of TPO-RAs decline with the introduction of generic formulations, TPO-RAs may be increasingly cost-effective.

The use of IVF/ICSI and risk of postpartum hemorrhage: A retrospective cohort study of 153,765 women in China.

Objective: Postpartum hemorrhage (PPH) is the leading cause of maternal morbidity and mortality. Identifying women who are at high risk of PPH is crucial for implementing early preventive and interventive strategies. This study aimed to examine whether there is an association between the use of in vitro fertilization (IVF) /intracytoplasmic sperm injection (ICSI) and increased risk of PPH. Method: This retrospective cohort study was conducted using medical record data from women who delivered at a tertiary hospital in Shanghai, China, between January 1, 2013 and April 30, 2019. Logistic regression analysis was used to estimate the associations between the use of IVF/ICSI and the risk of PPH. Results: A total of 153,765 pregnant women were included, of which 6,484 conceived through IVF/ICSI and147,281 conceived naturally. The incidence of PPH was 1.9% in this cohort. The incidence of PPH in women who conceived through IVF/ICSI was significantly higher than those in women who conceived naturally (3.4% vs. 1.7%, p < 0.01). The use of IVF/ICSI was associated with an increase in the amount of postpartum blood loss. Compared to women who conceived naturally, the average amount of postpartum blood loss increased by 42.1 mL (ß = 42.1, 95% CI, 38.2-46.0) for women who conceived through IVF/ICSI. In addition, women who conceived through IVF/ICSI were at higher risk of maternal PPH. The adjusted odds ratio (OR) of PPH in women who conceived through ART was 2.7 (OR = 2.7, 95% CI, 2.3-3.1). Conclusion: Our findings demonstrated that women who conceived through IVF/ICSI were at higher risk of PPH and suggested to obstetricians and midwives to identify and implement early preventative strategies for PPH among pregnant women who conceived through IVF/ICSI.

Impact of the Health Gym Program on hospital admissions for stroke in the state of Pernambuco, Brazil.

This study aimed to evaluate the impact of the Health Gym Program (HGP) on hospital admissions for stroke in the state of Pernambuco, Brazil. This policy impact evaluation used a quasi-experimental approach consisting of a difference-in-differences estimator, weighted by propensity score matching to deal with potential confounding variables. The study comprised socioeconomic, demographic, and epidemiological data from official Brazilian databases from 2010 to 2019. The treatment group was composed of the 134 municipalities that implemented the HGP since 2011. The 51 municipalities that did not were allocated to the comparison group. The nearest neighbor algorithm (N5) was used to pair treatment and comparison group municipalities and create the weights to evaluate the average treatment effect on the treated (ATT) in the difference-in-differences estimator. In 2010, 2,771 people were hospitalized for stroke (0.51% of all hospitalizations) and in 2019, 11,542 (2%). Municipalities that implemented the HGP had 18.37% fewer hospitalizations than their counterparts in the comparison group. The program's impact in reducing hospitalization rates was incrementally greater among men (ATT: -0.1932) and those aged 71 to 80 years (ATT: -0.1911). All results were statistically significant at the 5% level. The HGP reduced hospitalization for stroke in several population groups, but primarily in those whose underlying prevalence of stroke is highest, reinforcing the importance of public investments in health promotion policies designed to encourage lifestyle changes.

The Effect of a Long-Term Care Insurance Program on Subjective Well-Being of Older Adults with a Disability: Quasi-Experimental Evidence from China.

China launched its long-term care insurance (LTCI) program for older adults in 2016. Although the scheme has shown some promising outcomes, little is known about whether it improves subjective well-being. This study explored this topic among older persons with a disability and identified the underlying mechanisms associated with the channel of this effect using data from a national survey. The LTCI program was shown to improve the subjective well-being among older persons with a disability and this effect increased over time. The LTCI program has great positive effect among women and those who lived alone compared to their counterparts. Mechanism analysis revealed that the main channel by which the LTCI program has positive effect occurred through the satisfaction of long-term care needs and improved self-reported health. This study suggests promising benefits of the LTCI program for older Chinese adults.

The Association Between Work Environment, Work Attitudes, and Turnover Intentions Among Geriatric Social Workers in China.

The psychological state of geriatric social workers affects the intention to leave and thus the quality of services provided to older adults. This study explored the relationship between the work environment, work attitudes, and turnover intentions of geriatric social workers. This study obtained an analytic sample comprising 999 geriatric social workers from the 2019 Longitudinal Study of Social Work in China. Multivariate regression techniques combined with a mediation analysis was performed to explore the relationships. The study results provided preliminary evidence on the complex associations between and among work environment, work attitudes, and turnover intentions of geriatric social workers in China. We demonstrated that perceived organizational support reduced the turnover intentions of geriatric social workers through increased collective psychological ownership and reduced burnout. Regular inter- and intra-agency communication between social workers and their supervisors and colleagues have important roles in reducing turnover by enhancing support and emotional commitment to organizations. Policy decision-makers are suggested to clearly define the roles and responsibilities of geriatric social works to release their administrative burdens, which may help to reduce their burnout level and improve the stability of the geriatric social work force.

O estudo teve como objetivo avaliar o impacto do Programa Academia da Saúde (PAS) nas internações hospitalares por acidente vascular cerebral (AVC) no Estado de Pernambuco, Brasil. Esta avaliação de impacto das políticas utilizou uma abordagem quase-experimental que consiste em um estimador de diferença-em-diferenças, ponderado pelo pareamento por escore de propensão para lidar com possíveis fatores de confusão. O estudo foi composto por dados socioeconômicos, demográficos e epidemiológicos de bases de dados oficiais brasileiras entre os anos de 2010 e 2019. O grupo de tratamento foi composto pelos 134 municípios que implantaram o PAS a partir de 2011, e os 51 municípios que não implantaram foram alocados no grupo de comparação. O algoritmo do vizinho mais próximo (N5) foi utilizado para emparelhar os municípios tratados e comparar aos municípios do grupo controle, criando os pesos que foram utilizados para avaliar o efeito médio do tratamento sobre o tratado (ATT) no estimador de diferença-em-diferenças. Houve 2.771 internações por AVC em 2010 (0,51% de todas as internações) e 11.542 (2%) em 2019. Os municípios que implementaram o PAS tiveram 18,37% menos internações em comparação com seus homólogos no grupo de comparação. O impacto do programa na redução das taxas de internação foi maior entre os homens (ATT: -0,1932) e naqueles com idade entre 71 e 80 anos (ATT: -0,1911). Todos os resultados foram estatisticamente significativos em um nível de 5%. O PAS reduziu a hospitalização por AVC em vários grupos populacionais, mas principalmente naqueles em que a prevalência subjacente de AVC é mais alta, reforçando a importância dos investimentos públicos em políticas de promoção da saúde destinadas a estimular mudanças nos estilos de vida.

El objetivo de este trabajo es evaluar el impacto del Programa Academia de la Salud (PAS) en los ingresos hospitalarios por accidente cerebrovascular (ACV) en el estado de Pernambuco, Brasil. Esta evaluación del impacto de la política utilizó un enfoque cuasi-experimental que consiste en un estimador de diferencias en diferencias, ponderado por el emparejamiento de puntuación de propensión para hacer frente a posibles factores de confusión. El estudio incluyó datos socioeconómicos, demográficos y epidemiológicos de bases de datos oficiales brasileñas de 2010 a 2019. El grupo de tratamiento se compuso de los 134 municipios que implementaron el PAS a partir de 2011 y los 51 municipios que no lo hicieron se asignaron al grupo de comparación. Se utilizó el algoritmo del vecino más próximo (N5) para emparejar los municipios tratados y los del grupo de comparación y crear las ponderaciones que se emplearon para evaluar el efecto medio del tratamiento sobre los tratados (ATT) en el estimador de diferencias en diferencias. Hubo 2.771 hospitalizaciones por ACV en 2010 (0,51% de todas las hospitalizaciones) y 11.542 (2%) en 2019. Los municipios que aplicaron el PAS tuvieron un 18,37% menos de hospitalizaciones en comparación con sus homólogos del grupo de comparación. El impacto del programa en la reducción de las tasas de hospitalización fue gradualmente mayor entre los hombres (ATT: -0,1932) y entre las personas de 71 a 80 años (ATT: -0,1911). Todos los resultados fueron estadísticamente significativos al nivel del 5%. El PAS redujo la hospitalización por ACV en varios grupos de población, pero principalmente en aquellos en los que la prevalencia subyacente de ACV es mayor, lo que refuerza la importancia de las inversiones públicas en políticas de promoción de la salud diseñadas para impulsar cambios en los estilos de vida.

Does the provision of informal care matter for caregivers' mental health? Evidence from China.

This paper investigates the causal effect of informal care on the mental health of caregivers and disentangles the mechanisms of such effect. Using 2011-2018 CHARLS data, the fixed effects and instrumental variable approaches was conducted to address fundamental endogeneity problems. This study found that there was no impact of informal caregiving on caregivers' mental health in general. However, the intensity of caregiving was shown to negatively impair mental health. The impact of informal caregiving varied by kinship, cultural context, and residential area. Participation in social and exercise activities and life satisfaction mediated the association between the provision of informal care and caregivers' mental health. Long-term care insurance and the provision of formal care substantially modified the negative impacts of informal caregiving.

The Relationship between the Unmet Needs of Chinese Family Caregivers and the Quality of Life of Childhood Cancer Patients Undergoing Inpatient Treatment: A Mediation Model through Caregiver Depression.

A large proportion of the global burden of childhood cancer arises in China. These patients have a poor quality of life (QoL) and their family caregivers have high unmet needs. This paper examined the association between the unmet needs of family caregivers and the care recipient's QoL. A total of 286 childhood cancer caregivers were included in this cross-sectional study. Unmet needs and depression among caregivers were assessed by the Comprehensive Needs Assessment Tool for Cancer Caregivers (CNAT-C) and the Patient Health Questionnaire (PHQ-9), respectively. The patient's QoL was proxy-reported by the Pediatric Quality of Life Inventory Measurement Models (PedsQL 3.0 scale Cancer Module). Descriptive analyses, independent Student's t-tests, one-way ANOVA, and mediation analyses were performed. The mean scores (standard deviations) for unmet needs, depression, and QoL were 65.47 (26.24), 9.87 (7.26), and 60.13 (22.12), respectively. A caregiver's unmet needs (r = −0.272, p < 0.001) and depression (r = −0.279, p < 0.001) were negatively related to a care recipient's QoL. Depression among caregivers played a mediating role in the relationship between a caregiver's unmet needs and a care recipient's QoL. As nursing interventions address depression among caregivers, it is important to standardize the programs that offer psychological support to caregivers.

The impact of provincial lockdown policies and COVID-19 case and mortality rates on anxiety in Canada.

AIM: COVID-19 has had significant mental health impacts internationally and anxiety rates are estimated to have tripled during the pandemic, but the specific causes remain underexplored. This study's purpose was to investigate the associations of sociodemographic factors, COVID-19-related policies, and COVID-19 case/mortality rates with levels of anxiety among Canadians during the pandemic. METHODS: This study used linear regression models populated with three integrated sources of data: a repeated cross-sectional survey (n = 7008), Oxford COVID-19 Government Response Tracker data, and COVID-19 case/mortality rates. Sociodemographic factors included were age, gender, race, province, income, education, rurality, household composition, and factors related to employment. RESULTS: Local COVID-19 case and mortality rates and stay-at-home orders were positively associated with anxiety symptom severity. Anxiety was most severe among those who: were female, Indigenous, or Middle Eastern; had postsecondary education; lived with others; and became unemployed or had working hours altered during the pandemic. Anxiety was less severe among: older adults; male, Caucasians, and black individuals; those with high incomes, and; those for whom employment did not change during the pandemic. CONCLUSION: Anxiety was primarily driven by socioeconomic factors among Canadians during the COVID-19 pandemic. Policies that alleviate socioeconomic uncertainty for groups that are most vulnerable may reduce the long-term harm of the pandemic and associated lockdown policies.

Healthcare Utilization and Costs for Musculoskeletal Disorders in Ontario, Canada.

OBJECTIVE: To examine the magnitude and costs of ambulatory primary care, specialist physician care, and hospital service use for musculoskeletal disorders (MSDs) in Canada's largest province, Ontario. METHODS: Administrative health databases were analyzed for fiscal year 2013-2014 for adults aged ≥ 18 years, including data on physician services, emergency department (ED) visits, and hospitalizations. International Classification of Diseases diagnostic codes were used to identify MSD services. A validated algorithm was used to estimate direct medical costs. Person-visit rates and numbers of persons and visits were tabulated by care setting, age, sex, and physician specialty. Data were examined for all MSDs combined, as well as for specific diagnostic groupings. RESULTS: Overall, 3.1 million adult Ontarians (28.5%) made over 8 million outpatient physician visits associated with MSDs. These included 5.6 million primary care visits. MSDs accounted for 560,000 (12.3%) of all adult ED visits. Total costs for MSD-related care were $1.6 billion, with 12.6% of costs attributed to primary care, 9.2% to specialist care, 8.6% to ED care, 8.5% to day surgery, and 61.2% associated with inpatient hospitalizations. Costs due to arthritis accounted for 40% of total MSD care costs ($639 million). MSD-related imaging costs were $169 million, yielding a total cost estimate of $1.8 billion for MSDs overall. CONCLUSION: MSDs place a significant and costly burden on the healthcare system. Health system planning needs to consider the large and escalating demand for care to reduce both the individual and population burden.

The effect of the two-child policy on cesarean section in China: Identification using difference-in-differences techniques.

BACKGROUND: China has one of the highest rates of cesarean section in the world. One of the possible reasons for such high rates was China's one-child policy. Relaxation of the one-child policy might be associated with a reduction in the rate of cesarean section. OBJECTIVES: To assess the effect of China's universal two-child policy on cesarean section rates using patient-level data from one large municipal-level obstetrics and gynecology hospital in Shanghai, East China. DATA SOURCES: The study used inpatient hospital records data on all infants delivered between January 1, 2013 and May 31, 2018 at the Shanghai First Maternity and Infant Hospital, which is one of the largest obstetrical hospitals in China. STUDY DESIGN: A quantitative study design with difference-in-differences (DID) estimation techniques were used to control for socio-economic and health-related factors in order to identify the impact of the universal two-child policy on cesarean section rates in China. Moreover, DID analysis stratified by maternal migrant status and age were conducted. RESULTS: Analysis of 133,358 deliveries suggests that China's universal two-child policy resulted in a statistically significant reduction in cesarean section rates from 49.5 to 43.3 per 100 deliveries over the study period. CONCLUSION: Our findings suggest that the significant reduction in cesarean section rates may be due to a shift in health risk perceptions resulting from the relaxation of the one-child policy when mothers consider the possibility of having a second child. Health education on the risk of repeat cesarean section in pregnant women should be enhanced.

The Effect of China's Two-Child Policy on the Child Sex Ratio: Evidence From Shanghai, China.

OBJECTIVE: The bias towards males at birth has resulted in a major imbalance in the Chinese sex ratio that is often attributed to China's one-child policy. Relaxation of the one-child policy has the potential to reduce the imbalance in the sex ratio away from males. In this study, we assessed whether the bias towards males in the child sex ratio was reduced as a result of the two-child policy in China. Medical records data from one large municipal-level obstetrics hospital in Shanghai, East China. DESIGN: Matching and difference-in-differences (MDID) techniques were used to investigate the effect of the two-child policy on the imbalance in the sex ratio at birth after matching for pregnancy status and socioeconomic factors. RESULTS: Analyzing 133,358 live births suggest that the relaxation of the one-child policy had a small, but statistically significant effect in reducing the imbalance in the male to female sex ratio at birth. CONCLUSION: The results demonstrate that relaxation of the one-child policy reduced the imbalance in the male to female sex ratio at birth from 1.10 to 1.05 over the study period at one of the major obstetrics and gynecology hospitals in China.

Research on the child healthcare system in China from the perspective of equal health benefits: Beijing as the case study.

BACKGROUND: With government's proposal of the Healthy China Strategy, universal health has become the focus of increasing attention in China. As a special group, children's health is the basis and start of the national health. The construction of children's healthcare system should be given the priority. This study applied the concept of health equal benefits and conducted a systematic and in-depth theoretical and empirical research on the children's healthcare system in Beijing, aiming at proposing relevant countermeasures and suggestions such as constructing the path of children's health care system in China. METHODS: This study adopted the way of questionnaire on children's basic information, health status, health service demand, insured situation and system satisfaction and then analysed the children's health, healthcare, satisfaction influence factors and their healthcare needs based on a survey in Beijing China. Methods such as descriptive statistics, analysis of variance and logistic regression are adopted to analyse the correlation between factors affecting children's health. RESULTS: The findings show that overall health of the children in Beijing was better. However, there are still problems such as insufficient resource coverage and incorrect cognition in some groups. Their mental health and support need to be put emphasis on. The popularization of medical insurance policies for urban and rural residents in Beijing needs to be further improved. The burden of seeing a doctor is slightly lower than before, and the contribution to protecting children's health is not strong enough. CONCLUSIONS: Through the survey of children in Beijing, it can be seen that there are still some problems existing in the healthcare system of children in China from the perspective of equal benefit. This study draws policy attention to the issues of financing, service contents, targets, service level and the degree of social recognition.

Impacts of Absolute and Relative Income on Self-Rated Health in Urban and Rural China.

This study aims to assess the impacts of absolute and relative income on self-rated health (SRH) of residents in rural and urban China. Data were derived from the China Health and Nutrition Survey. Three distinct measures of relative income were considered (Gini coefficient, Yitzhaki index, and Deaton index) and computed for 3 geographic units (nation, province, and community). Nonlinear dynamic models for panel data were employed to test the absolute and relative income hypotheses. Absolute income was significantly associated with SRH among urban and rural populations. Relative income, as measured by the Gini coefficient, the Yitzhaki index, and the Deaton index, had statistically significant and negative impacts on SRH among the rural population, regardless of the reference group. For the urban population, the Gini coefficient was associated with SRH regardless of the reference group. In contrast, only the Yitzhaki index and the Deaton index at the provincial level were associated with SRH among the urban population. Our findings may provide a reference for policymakers to implement health policies designed to improve population health.

The impact of environmental pollution on the physical health of middle-aged and older adults in China.

While several studies have demonstrated the negative impacts of environmental pollution on population health, in general, few studies have examined the potential differential effects on the physical health of middle-aged and older populations, i.e., 45 years and older. Given the twin concerns of environmental pollution and population aging in China, this article employed a fixed effects model to infer the impact of environmental pollution on public health with a particular focus on middle-aged and older adults. The analyses were based on data from the 2011 to 2018 waves of the CHARLS and pollutant data from prefecture-level cities. The results showed that both the level and intensity of environmental pollution significantly increased the risk of chronic diseases and negatively impacted the physical health of middle-aged and older adults. Environmental pollution had its greatest negative effect on the physical health of the elderly, urban residents, residents of the Eastern region, and those with lower incomes than their counterparts. We further found that the potential channels of health effect were through reduced physical exercise and sleep duration and an increase in depressive symptoms, and the pollution prevention actions alleviated the health deterioration of environmental pollution for the middle-aged and the elderly. It is imperative for the government to urgently reinforce policy enforcement to decrease air and water pollution and enhance the ability to circumvent pollution for the lower socioeconomic groups.

Frailty is an important predictor of 30-day morbidity in patients treated for lumbar spondylolisthesis using a posterior surgical approach.

BACKGROUND CONTEXT: Traditionally, a nonoperative approach has been favored for elderly patients with lumbar spondylolisthesis due to a perceived higher risk of morbidity with surgery. However, most studies have used an arbitrary age cut-off to define "elderly" and this research has yielded conflicting results. PURPOSE: The purpose of this study was to investigate the impact of frailty on morbidity after surgery for degenerative lumbar spondylolisthesis treated with a posterior approach. STUDY DESIGN: A retrospective cohort study was performed. PATIENT SAMPLE: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database, with years 2010 to 2018 included in this study. Patients who received posterior lumbar spine decompression with or without single level posterior instrumented fusion for degenerative lumbar spondylolisthesis were included. Patients who received anterior and/or lateral approaches were excluded. OUTCOME MEASURES: The primary outcome was Clavien-Dindo grade IV complication. Secondary outcomes were readmission, reoperation, and discharge to location other than home. METHODS: Patient demographics and comorbidities were extracted. Logistic regression analysis was performed to investigate the association between outcomes and the Modified Frailty Index-5, adjusting for age, gender, body mass index, smoking status, and surgical procedure performed. A sub-analysis was done to assess the effect of frailty in three different age groups (18-45 years, 46-65 years, and >65 years) for the two surgical cohorts. RESULTS: There were 15,658 patients in this study. The mean age was 62.5 years. Approximately 70% of the patients received decompression with fusion. Frailty was significantly associated with an increased risk of major complication, unplanned readmission, reoperation, and non-home discharge. The risk increased with increasing frailty. For patients who received decompression, frailty was associated with a higher risk of readmission and non-home discharge in patients >65 years. For patients who received decompression and fusion, frailty was associated with a higher risk of complications, readmission, and non-home discharge in patients >65 years. CONCLUSIONS: Frailty is independently associated with a higher risk of morbidity after posterior surgery in patients with lumbar spondylolisthesis, especially in patients older than 65. These data are of significance to clinicians in planning treatment for these patients.
