Opthalmic impairment at 7 years of age in children born very preterm

Aims: To determine the prevalence of ophthalmic impairments in very preterm compared with term infants, the relation between impairments and cerebral ultrasound appearances and retinopathy, and the correlation with visual perception and motor and cognitive measures. Subjects: 279 children at 7 years of age born before 32 weeks gestation within Liverpool during 1991–92 and attending mainstream schools, and 210 term controls. Methods: Visual acuity was assessed by Snellen chart, and strabismus by the cover test. Stereopsis was determined using the TNO random dot test, and contrast sensitivity using the Cambridge low contrast gratings. Visual and motor abilities were assessed using the Developmental test of motor integration (VMI) and the Movement ABC. Intelligence was measured with the Wechsler intelligence scale for children UK. Perinatal cranial ultrasound and retinopathy data were extracted from clinical records. Results: Children born preterm were significantly more likely to wear glasses, to have poor visual acuity, reduced stereopsis, and strabismus than term controls, but they showed no significant decrease in contrast sensitivity. Ophthalmic impairments were significantly related to poorer scores on the VMI, Movement ABC, and Wechsler IQ tests, but were not significantly related to neonatal cranial ultrasound appearances. Stage 3 retinopathy was related to poorer subsequent acuity. Conclusions: Children born very preterm and without major neurodevelopmental sequelae have an increased prevalence of ophthalmic impairments at primary school age which are associated with visual perceptional, motor, and cognitive defects. The cause may be a generalised abnormality of cortical development rather than perinatally acquired focal lesions of the brain

Socio-demographic determinants of the severity of locomotor disability among adults in Bangladesh: a cross-sectional study, December 2010-February 2011.

BACKGROUND: Socio-demographic variables are widely known to have an association with the presence of any disability. However, the association between the severity of locomotor disability and socio-demographic variables has never been investigated in Bangladesh. METHODS: A cross sectional survey of adults with locomotor disabilities was conducted between December 2010 and February 2011 at the Centre for the Rehabilitation of the Paralysed (CRP), Dhaka, Bangladesh. During the study period 328 adults with locomotor disabilities met our selection criteria, but 316 consented and participated in the study. The 55-item Locomotor Disability Scale was used to measure disability. This study investigated the socio-demographic determinants of the severity of locomotor disability: age, gender, marital status, educational attainment, occupation, income status, type of house, living in own/rented house, household monthly income, household population and area of residence. RESULTS: Participants' age was positively associated with the severity of their locomotor disability (β = 0.01; 95% CI: 0.004 to 0.02), adjusting for diagnosis and other socio-demographic variables studied. Individuals who had an income experienced 0.35 (95% CI: -0.63 to -0.07) points decrease in the severity of disability than those did not have an income, adjusting for diagnosis and rest of the socio-demographic variables studied. In comparison to the unemployed individuals, students, homemakers, and individuals in elementary occupation respectively experienced 0.75 (95% CI: -1.08 to -0.43), 0.51 (95% CI: -0.82 to -0.19) and 0.37 (95% CI: -0.66 to -0.08) points decrease in the severity of locomotor disability, adjusting for diagnosis and rest of the socio-demographic variables studied. CONCLUSIONS: The severity of locomotor disability has an association with individuals' age, income status and occupation of the adults with such disability in Bangladesh. No such association was evident with other socioeconomic position and demographic variables. This finding suggests that people with locomotor disabilities in Bangladesh experience similar disabling built and attitudinal environments irrespective of their socioeconomic positions and demographic characteristics. Further community-based studies are needed to confirm such conclusions

Free-choice learning in school science : a model for collaboration between formal and informal science educators

The informal science education sector has been found to foster engagement with science, whereas formal science education has been criticised as disconnected from students’ lives and experiences. Consequently, there have been calls for greater collaboration between formal and informal sectors. This study aimed to create such a ‘third space’ for science education by linking a university science educator with schools to create spaces for increased student choice in learning. The community of inquiry pedagogical model was used to manage a series of discussions about cutting edge science with 507 students aged 11-14 in 20 state schools in the UK. These classes substituted for school science lessons. Studying learning in free choice environments is challenging due to the range of possible outcomes. Data was collected using participant observations, questionnaires and interviews. Teachers’ and students’ responses were analysed using Falk and Dierking’s Contextual Model of Learning. This allowed us to consider the totality of students’ experiences whilst acknowledging the complexity of free choice spaces. Findings indicate that this third space allowed students to exercise choice and control over their learning, and to connect science with their prior knowledge and interests. However, choice can also act as a barrier to learning if students lack sufficient prior knowledge or are uncomfortable with content. Students identified the role of peers and facilitated discussion as important. This indicates that there are benefits to opening up spaces for free choice learning in school science, and we suggest the community of inquiry as a model to achieve this

Hospitalisation trends in India from serial cross-sectional nationwide surveys: 1995 to 2014.

OBJECTIVES: We report hospitalisation trends for different age groups across the states of India and for various disease groups, compare the hospitalisation trends among the older (aged 60 years or more) and the younger (aged under 60 years) population and quantify the factors that contribute to the change in hospitalisation rates of the older population over two decades. DESIGN: Serial cross-sectional study. SETTING: Nationally representative sample, India. DATA SOURCES: Three consecutive National Sample Surveys (NSS) on healthcare utilisation in 1995-1996, 2004 and 2014. PARTICIPANTS: Six hundred and thirty-three thousand four hundred and five individuals in NSS 1995-1996, 385 055 in NSS 2004 and 335 499 in NSS 2014. METHODS: Descriptive statistics, multivariable analyses and a regression decomposition technique were used to attain the study objectives. RESULT: The annual hospitalisation rate per 1000 increased from 16.6 to 37.0 in India from 1995-1996 to 2014. The hospitalisation rate was about half in the less developed than the more developed states in 2014 (26.1 vs 48.6 per 1000). Poor people used more public than private hospitals; this differential was higher in the more developed (40.7% vs 22.9%) than the less developed (54.3% vs 40.1%) states in 2014. When compared with the younger population, the older population had a 3.6 times higher hospitalisation rate (109.9 vs 30.7) and a greater proportion of hospitalisation for non-communicable diseases (80.5% vs 56.7%) in 2014. Among the older population, hospitalisation rates were comparatively lower for females, poor and rural residents. Propensity change contributed to 86.5% of the increase in hospitalisation among the older population and compositional change contributed 9.3%. CONCLUSION: The older population in India has a much higher hospitalisation rate and has continuing greater socioeconomic differentials in hospitalisation rates. Specific policy focus on the requirements of the older population for hospital care in India is needed in light of the anticipated increase in their proportion in the population

Horizontal inequity in outpatient care use and untreated morbidity: evidence from nationwide surveys in India between 1995 and 2014.

Equity in healthcare has been a long-term guiding principle of health policy in India. We estimate the change in horizontal inequities in healthcare use over two decades comparing the older population (60 years or more) with the younger population (under 60 years). We used data from the nationwide healthcare surveys conducted in India by the National Sample Survey Organization in 1995-96 and 2014 with sample sizes 633 405 and 335 499, respectively. Bivariate and multivariate logit regression analyses were used to study the socioeconomic differentials in self-reported morbidity (SRM), outpatient care and untreated morbidity. Deviations in the degree to which healthcare was distributed according to need were measured by horizontal inequity index (HI). In each consumption quintile the older population had four times higher SRM and outpatient care rate than the younger population in 2014. In 1995-96, the pro-rich inequity in outpatient care was higher for the older (HI: 0.085; 95% CI: 0.066, 0.103) than the younger population (0.039; 0.034, 0.043), but by 2014 this inequity became similar. Untreated morbidity was concentrated among the poor; more so for the older (-0.320; -0.391, -0.249) than the younger (-0.176; -0.211, -0.141) population in 2014. The use of public facilities increased most in the poorest and poor quintiles; the increase was higher for the older than the younger population in the poorest (1.19 times) and poor (1.71 times) quintiles. The use of public facilities was disproportionately higher for the poor in 2014 than in 1995-96 for the older (-0.189; -0.234, -0.145 vs - 0.065; -0.129, -0.001) and the younger (-0.145; -0.175, -0.115 vs - 0.056; -0.086, -0.026) population. The older population has much higher morbidity and is often more disadvantaged in obtaining treatment. Health policy in India should pay special attention to equity in access to healthcare for the older population

Inequity in out-of-pocket payments for hospitalisation in India: Evidence from the National Sample Surveys, 1995-2014.

OBJECTIVE: We report inequity in out-of-pocket payments (OOPP) for hospitalisation in India between 1995 and 2014 contrasting older population (60 years or more) with a population under 60 years (younger population). METHODS: We used data from nationwide healthcare surveys conducted in India by the National Sample Survey Organisation in 1995-96, 2004 and 2014 with the sample sizes ranging from 333,104 to 629,888. We used generalised linear and fractional response models to study the determinants of OOPP and their burden (share of OOPP in household consumption expenditure) at a constant price. The relationship between predicted OOPP and its burden with monthly per capita consumption expenditure (MPCE) quintiles and selected socioeconomic characteristics were used to examine vertical and horizontal inequities in OOPP. RESULTS: The older population had higher OOPP for hospitalisation at all time points (range: 1.15-1.48 times) and a greater increase between 1995-96 and 2014 than the younger population (2.43 vs 1.88 times). Between 1995-96 and 2014, the increase in predicted mean OOPP for hospitalisation was higher for the poorest than the richest (3.38 vs 1.85 times) older population. The increase in predicted mean OOPP was higher for the poorest (2.32 vs 1.46 times) and poor (2.87 vs 1.05 times) older population between 1995-96 and 2004 than in the latter decade. In 2014, across all MPCE quintiles, the burden of OOPP was higher for the less developed states, females, private hospitals, and non-communicable disease and injuries, more so for the older than the younger population. In 2014, the predicted absolute OOPP for hospitalisation was positively associated with MPCE quintiles; however, the burden of OOPP was negatively associated with MPCE quintiles indicating a regressive system of healthcare financing. CONCLUSION: High OOPP for hospitalisation and greater inequity among older population calls for better risk pooling and prepayment mechanisms in India

Factorial structure of the locomotor disability scale in a sample of adults with mobility impairments in Bangladesh.

BACKGROUND: Disability does not only depend on individuals' health conditions but also the contextual factors in which individuals live. Therefore, disability measurement scales need to be developed or adapted to the context. Bangladesh lacks any locally developed or validated scales to measure disabilities in adults with mobility impairment. We developed a new Locomotor Disability Scale (LDS) in a previous qualitative study. The present study developed a shorter version of the scale and explored its factorial structure. METHODS: We administered the LDS to 316 adults with mobility impairments, selected from outpatient and community-based settings of a rehabilitation centre in Bangladesh. We did exploratory factor analysis (EFA) to determine a shorter version of the LDS and explore its factorial structure. RESULTS: We retained 19 items from the original LDS following evaluation of response rate, floor/ceiling effects, inter-item correlations, and factor loadings in EFA. The Eigenvalues greater than one rule and the Scree test suggested a two-factor model of measuring locomotor disability (LD) in adults with mobility impairment. These two factors are 'mobility activity limitations' and 'functional activity limitations'. We named the higher order factor as 'locomotor disability'. This two-factor model explained over 68% of the total variance among the LD indicators. The reproduced correlation matrix indicated a good model fit with 14% non-redundant residuals with absolute values > 0.05. However, the Chi-square test indicated poor model fit (p  .91. Among the retained 19 items, there was no correlation coefficient > .9 or a large number of correlation coefficients .3) cross loadings and the correlation between the two factors was .657. The 'mobility activity limitations' and 'functional activity limitations' sub-scales demonstrated excellent internal consistency (Cronbach's alpha were .954 and .937, respectively). CONCLUSIONS: The 19-item LDS was found to be a reliable and valid scale to measure the latent constructs mobility activity limitations and functional activity limitations among adults with mobility impairments in outpatient and community-based settings in Bangladesh

Trends in catastrophic health expenditure in India: 1993 to 2014.

OBJECTIVE: To investigate trends in out-of-pocket health-care payments and catastrophic health expenditure in India by household age composition. METHODS: We obtained data from four national consumer expenditure surveys and three health-care utilization surveys conducted between 1993 and 2014. Households were divided into five groups by age composition. We defined catastrophic health expenditure as out-of-pocket payments equalling or exceeding 10% of household expenditure. Factors associated with catastrophic expenditure were identified by multivariable analysis. FINDINGS: Overall, the proportion of catastrophic health expenditure increased 1.47-fold between the 1993-1994 expenditure survey (12.4%) and the 2011-2012 expenditure survey (18.2%) and 2.24-fold between the 1995-1996 utilization survey (11.1%) and the 2014 utilization survey (24.9%). The proportion increased more in the poorest than the richest quintile: 3.00-fold versus 1.74-fold, respectively, across the utilization surveys. Catastrophic expenditure was commonest among households comprising only people aged 60 years or older: the adjusted odds ratio (aOR) was 3.26 (95% confidence interval, CI: 2.76-3.84) compared with households with no older people or children younger than 5 years. The risk was also increased among households with both older people and children (aOR: 2.58; 95% CI: 2.31-2.89), with a female head (aOR: 1.32; 95% CI: 1.19-1.47) and with a rural location (aOR: 1.27; 95% CI: 1.20-1.35). CONCLUSION: The proportion of households experiencing catastrophic health expenditure in India increased over the past two decades. Such expenditure was highest among households with older people. Financial protection mechanisms are needed for population groups at risk for catastrophic health expenditure
