Evaluation of the Acute flaccid paralysis surveillance indicators in Zambia from 2015-2021: a retrospective analysis.

BACKGROUND: The resurgence of poliovirus infection in previously polio free regions and countries calls for renewed commitment to the global polio eradication efforts including strengthening of Acute Flaccid Paralysis (AFP) surveillance systems. Zambia is one of the countries substantially at risk for the importation of poliovirus infection from neighbouring countries including Malawi, Mozambique, and Democratic Republic of the Congo (DRC). This study describes a seven-year AFP surveillance, assesses the surveillance indicators, and highlights areas for improvement. METHODS: We conducted retrospective analysis of the routinely collected AFP surveillance data from January 2015 to December 2022. The AFP surveillance indicators performance was assessed using the World Health Organisation's recommended minimum AFP surveillance indicators performance. RESULTS: Cumulatively, a total of 1715 AFP cases were reported over the study period. More than half, 891 (52%) of reported cases were aged < 5 years with 917 (53.5%) of males. More than half, 1186 (69.2%) had fever at onset, 718 (41.9%) had asymmetric paralysis and 1164 (67.9%) had their paralysis progressed within 3 days of onset. The non-polio AFP rate ranges from 3.4 to 6.4 per 100,000 children < 15 years old and stool adequacy ranging from 70.9% to 90.2% indicating sensitive surveillance with late detection of cases. The percentage of cases with early stool collection, timely transportation was above the World Health Organisation (WHO) minimum of 80% but with declining proportion of stools arriving in the laboratory in optimal condition. Completeness of 60-days follow-up evaluation was suboptimal ranging from 0.9% to 28.2%. CONCLUSION: The AFP surveillance system in Zambia is doing well. However, additional efforts are needed to improve early detection of cases; stool sample collection, transportation and monitoring to ensure arrival in good condition in the laboratory; and improve 60-days follow-up evaluation for evidenced-based classification of inadequate AFP cases and proper care.

Estimating the impact of work difficulties, work self-efficacy and work psychological safety on MS-related work productivity loss.

BACKGROUND: A comprehensive understanding of factors associated with multiple sclerosis (MS)-related work productivity loss will inform targeted interventions. We have previously shown the strong impact of symptom severity on MS-related work productivity loss. However, the effect of work difficulties, work self-efficacy and work psychological safety is yet to be well evaluated in this context. OBJECTIVES: This study evaluates the association between work difficulties, work self-efficacy and work psychological safety, and MS-related presenteeism, absenteeism and total work productivity loss. METHODS: We analysed data from employed participants of the Australian MS Longitudinal Study (AMSLS) who took part in both the 2015 Medication and Disease Course survey, and 2015 Employment survey (n = 744). Data were analysed using Cragg Hurdle regression models. RESULTS: We found that low workplace self-esteem, interpersonal difficulties at work and work self-efficacy were associated with total work productivity loss. In a multivariable model, a 10-unit decrease in workplace self-esteem, increase in interpersonal difficulties at work and 5-unit increase in work self-efficacy were independently associated with a 3.75% increase, 2.89% increase and 3.36% reduction in total work productivity loss, respectively. When separating total work productivity loss in presenteeism and absenteeism, stronger effects were seen for presenteeism than absenteeism. Surprisingly, work psychological safety was not associated with MS-related work productivity loss. CONCLUSION: Work psychosocial well-being such as self-confidence at work, work self-efficacy and interpersonal difficulties at work are crucial factors governing work productivity in people with MS (PwMS). Multidisciplinary support team assistance of PwMS in symptom self-care, skills around effective communication about MS in the workplace, the psychological impact of work and the modification of work demands may positively influence the employment outcomes.

Long-term trajectories of employment status, workhours and disability support pension status, after a first episode of CNS demyelination.

BACKGROUND: People with multiple sclerosis face significant employment-related challenges, with little known of the drivers of these outcomes. OBJECTIVE: We examined prospective trajectories of employment-related outcomes up to 11 years following a first episode of central nervous system (CNS) demyelination (FCD). METHODS: Participants were aged 18-59 years, at FCD, with at least two observations and were employed at study entry or anytime during follow-up (n = 207). Outcomes were employment status (full-time, part-time and unemployed), average workhours per week and disability support pension (DSP; receiving/not receiving). We used group-based trajectory modelling to identify groups with common trajectories. Factors associated with trajectory membership were explored using log-multinomial regression. RESULTS: Distinct trajectories were identified for employment (4), workhours (4) and DSP (2). Compared with stable full-time, female sex was strongly associated with being in the stable part-time trajectory (risk ratio (RR): 5.35; 95% confidence interval (CI) = 2.56-11.20; p < 0.001). A greater level of disability at 5-year review (RR: 1.35; 95% CI = 1.19-1.53) and having more than two comorbidities at baseline (RR: 2.77; 95% CI = 1.37-5.64) were associated with being in early and late deteriorated employment trajectories, respectively. Compared with the increased part-time trajectory, every additional relapse during the 5 years post-FCD was associated with a 10% increased risk of being in the reduced part-time trajectory (RR = 1.10; 95%CI = 1.00-1.22). For every additional EDSS point at 5-year review, the risk of being in the DSP trajectory increased (RR = 1.21; 95% CI = 1.05-1.41). CONCLUSION: These trajectories indicate substantial heterogeneity and the complex impact of MS on employment from its earliest timepoints. Understanding these trends could enable better targeting of interventions to facilitate workforce retention, particularly for females, those with a higher number of comorbidities, more frequent relapses and greater rate of disability accrual.

Development and psychometric properties of the Multiple Sclerosis Knowledge Assessment Scale: Rasch analysis of a novel tool for evaluating MS knowledge.

BACKGROUND: Multiple sclerosis (MS)-related knowledge is an important evaluation metric for health education interventions. However, few MS knowledge assessment tools are currently available for use. OBJECTIVES: This study aims to develop a reliable and valid Multiple Sclerosis Knowledge Assessment Scale (MSKAS) for use in the MS community and the general public. METHODS: The MSKAS was developed using a Delphi study methodology and was administered to participants in the first open enrolment of the Understanding Multiple Sclerosis (UMS) online course. Rasch analysis was used to examine its psychometric properties and develop the final scale. RESULTS: Experts from across the MS community participated in the development of the MSKAS, resulting in an initial scale of 42 items. Five hundred and forty-three UMS participants completed the MSKAS; 89% were female and 30% were people with MS. The final unidimensional 22-item scale has a person separation index of 2.16, a person reliability index of 0.82, an item separation index of 11.19, and a Cronbach's alpha (kr-20) test reliability of 0.87. CONCLUSION: The MSKAS is a unidimensional scale with good construct validity and internal consistency. The MSKAS has the potential to be useful for the assessment of MS knowledge in research and clinical practice.

Changes in multiple sclerosis symptoms are associated with changes in work productivity of people living with multiple sclerosis.

BACKGROUND: While employment rates have increased in people with multiple sclerosis (PwMS), little is known about the longitudinal trends of work productivity. OBJECTIVE: To describe the longitudinal patterns of work productivity and examine the factors associated with annual change of work productivity of PwMS. METHODS: Study participants were employed participants of the Australian MS Longitudinal Study (AMSLS) followed from 2015 to 2019 with at least two repeated measures (n = 2121). We used linear mixed models to examine if the within-individual variations in MS symptoms are associated with changes in work productivity. RESULTS: The mean annual change in work productivity between 2015 and 2019 was -0.23% (SD = 18.68%). Not the actual severity of symptoms but rather the changes in severity of symptoms that are associated with change in work productivity in the same year. In a multivariable model, every unit increase in mean annual change in 'pain and sensory symptoms', 'feelings of anxiety and depression', and 'fatigue and cognitive symptoms' were independently associated with 2.43%, 1.55% and 1.01% annual reductions in work productivity, respectively. CONCLUSION: Individual changes in work productivity are largely driven by the changes in symptom severity rather than the absolute severity. Stabilising/improving MS symptoms might improve work productivity.

Evaluating Course Completion, Appropriateness, and Burden in the Understanding Multiple Sclerosis Massive Open Online Course: Cohort Study.

BACKGROUND: Massive open online course (MOOC) research is an emerging field; to date, most research in this area has focused on participant engagement. OBJECTIVE: The aim of this study is to evaluate both participant engagement and measures of satisfaction, appropriateness, and burden for a MOOC entitled Understanding Multiple Sclerosis (MS) among a cohort of 3518 international course participants. METHODS: We assessed the association of key outcomes with participant education level, MS status, caregiver status, sex, and age using summary statistics, and 2-tailed t tests, and chi-square tests. RESULTS: Of the 3518 study participants, 928 (26.37%) were people living with MS. Among the 2590 participants not living with MS, 862 (33.28%) identified as formal or informal caregivers. Our key findings were as follows: the course completion rate among study participants was 67.17% (2363/3518); the course was well received, with 96.97% (1502/1549) of participants satisfied, with an appropriate pitch and low burden (a mean of 2.2 hours engagement per week); people living with MS were less likely than those not living with MS to complete the course; and people with a recent diagnosis of MS, caregivers, and participants without a university education were more likely to apply the material by course completion. CONCLUSIONS: The Understanding MS MOOC is fit for purpose; it presents information in a way that is readily understood by course participants and is applicable in their lives.

Risk factors associated with neonatal mortality among neonates admitted to neonatal intensive care unit of the University Teaching Hospital in Lusaka.

Globally, several children die shortly after birth and many more of them within the first 28 days of life. Sub-Sharan Africa accounts for almost half (43%) of the global neonatal death with slow progress in reduction. These neonatal deaths are associated with lack of quality care at or immediately after birth and in the first 28 days of life. This study aimed to determine the trends and risk factors of facility-based neonatal mortality in a major referral hospital in Lusaka, Zambia. We conducted retrospective analysis involving all neonates admitted in the University Teaching Hospital Neonatal Intensive Care Unit (UTH-NICU) in Lusaka from January 2018 to December 2019 (N = 2340). We determined the trends and assessed the factors associated with facility-based neonatal mortality using Generalized Linear Models (GLM) with a Poisson distribution and log link function. Overall, the facility-based neonatal mortality was 40.2% (95% CI 38.0-42.0) per 1000 live births for the 2-year period with a slight decline in mortality rate from 42.9% (95% CI 40.0-46.0) in 2018 to 37.3% (95% CI 35.0-40.0) in 2019. In a final multivariable model, home delivery (ARR: 1.70, 95% CI 1.46-1.96), preterm birth (ARR: 1.59, 95% CI 1.36-1.85), congenital anomalies (ARR: 1.59, 95% CI 1.34-1.88), low birthweight (ARR: 1.57, 95% CI 1.37-1.79), and health centre delivery (ARR: 1.48, 95% CI 1.25-1.75) were independently associated with increase in facility-based neonatal mortality. Conversely, hypothermia (ARR: 0.36, 95% CI 0.22-0.60), antenatal attendance (ARR: 0.76, 95% CI 0.68-0.85), and 1-day increase in neonatal age (ARR: 0.96, 95% CI 0.95-0.97) were independently associated with reduction in facility-based neonatal mortality. In this hospital-based study, neonatal mortality was high compared to the national and global targets. The improvement in neonatal survival observed in this study may be due to interventions including Kangaroo mother care already being implemented. Early identification and interventions to reduce the impact of risks factors of neonatal mortality in Zambia are important.

Correlates of Hepatitis B infection in pregnant women attending antenatal clinics in Wa Municipality, Ghana.

Despite the availability of an effective vaccine against viral hepatitis B infection, it remains prevalent, highly transmissible especially through mother-to-child, life-threatening, and a major public health challenge. A positive Hepatitis B e-Antigen (HBeAg) mother has a 90% risk of transmitting the virus to the unborn child in the perinatal period. This study sought to determine the prevalence and risk of Hepatitis B infection among pregnant women in the Wa Municipality of Ghana. A cross-sectional study employing systematic random sampling was conducted among 183 consented pregnant women who went for antenatal care in nine health facilities in the Wa Municipality. A structured validated questionnaire was used to collect information about socio-demographic and obstetric characteristics, awareness of Hepatitis B Virus (HBV) transmission and its prevention. Blood samples (3.0 mls) were collected from each participant to test for HBV serum markers using a Wondfo One Step HBV rapid immunochromatographic assay (Catalog number W003) for the Hepatitis B surface antigen (HBsAg). We conducted descriptive statistics including the prevalence and used multivariable logistic regression to determine the risk of Hepatitis B among study participants. Data was analysed using Stata/SE 15. About 20.2% of the 183 pregnant women screened tested positive for HBsAg. Generally, compared with younger pregnant women, older (> = 25) pregnant women were >9 times less likely to test positive for both chronic Hepatitis B core antibody (HBcAb) and (HBeAg) Hepatitis B infections. However, pregnant women in polygamous relationship were more likely to test positive for both (HBcAb) and (HBsAg and HBeAg) Hepatitis B infections compared with those in monogamous relationship. In a multivariable analysis, pregnant women in a polygamous relationships were about 5 times more likely to test positive for HBsAg (AOR = 4.61, 95% CI: 2.06-9.89) and HBcAb (AOR = 4.89, 95% CI:1.52-6.81) and HBeAg (AOR = 4.62, 95% CI:1.21-6.39) compared with those in a monogamous relationship. This study highlights a high HBsAg prevalence among pregnant women with those in polygamous relationship and younger age more likely to test positive. Facility and community-based health services should emphasize the need for regular screening, education, and vaccination of pregnant women, especially those at high risk, to prevent mother-to-child transmission of viral hepatitis B.

Measurement Properties of the Health Literacy Questionnaire in the Understanding Multiple Sclerosis Massive Open Online Course Cohort: A Rasch Analysis.

BACKGROUND: Online health education and other electronic health improvement strategies are developing rapidly, highlighting the growing need for valid scales to assess health literacy (HL). One comprehensive HL scale is the Health Literacy Questionnaire (HLQ), but little is known about its measurement properties in online health education cohorts. OBJECTIVE: The purpose of this study was to determine if the multidimensional HLQ is an appropriate tool to measure HL in a cohort of Understanding Multiple Sclerosis (MS) online course enrollees. METHODS: Participants who enrolled in the first two open enrollments of the Understanding MS online course completed the HLQ (N = 1,182) in an online survey prior to beginning course materials. We used Rasch analysis to assess the measurement properties of the HLQ. KEY RESULTS: The nine Domains of the HLQ each had ordered category function and a good fit with the Rasch model. Each domain was one-dimensional and exhibited good internal consistency and reliability. None of the 44 individual items of the HLQ demonstrated item bias or local dependency. However, while the overall fit was good, few measurement gaps were identified in this cohort for participants in each of the nine Domains, meaning that the HLQ may have low measurement precision in some participants. CONCLUSION: Our analysis of the HLQ indicated acceptable measurement properties in a cohort of Understanding MS online course enrollees. Although reliable information on nine separate constructs of HL was obtainable in the current study indicating that the HLQ can be used in similar cohorts, its limitations must be also considered. [HLRP: Health Literacy Research and Practice. 2022;6(3):e200-e212.] Plain Language Summary: In this study, we have shown that the HLQ is suitable for measuring HL in an online public health educational platforms for chronic diseases including multiple sclerosis. This finding adds to the evidence that the HLQ can be widely used in measuring HL in different settings, populations, and health educational platforms.

Gains in multiple sclerosis knowledge following completion of the Understanding Multiple Sclerosis online course are maintained six months after course completion.

BACKGROUND: Participation in the Understanding Multiple Sclerosis (MS) massive open online course (MOOC) significantly increases MS knowledge in both people living with MS (pwMS) and not living with MS at course completion. We also observed modest increases in health literacy, self-efficacy, and quality of life. OBJECTIVE: To examine long-term participant knowledge retention over a six-month follow-up period following completion of the Understanding MS MOOC, a freely available six-week online health education intervention. METHODS: We conducted pre-post analysis using paired t-tests to determine the effect of the course on MS knowledge (primary outcome), health literacy, resilience, self-efficacy, quality of life, and MS symptom severity among pwMS and not living with MS. We assessed the effect of participant characteristics on the change in MS knowledge using linear regression. RESULTS: Both pwMS (N=139) and not living with MS (N=164) significantly increased MS knowledge over the follow-up period. PwMS also showed increases in health literacy and self-efficacy. These increases were largely maintained from the post-course assessment. There was no effect on resilience or quality of life. CONCLUSIONS: The Understanding MS MOOC significantly increased MS knowledge and this knowledge was maintained six months after course completion. Our results reinforce the importance and potential impact of health education in the MS community.

Evaluating the impact of the Understanding Multiple Sclerosis online course on participant MS knowledge, health literacy, resilience, self-efficacy, quality of life, and MS symptom severity.

BACKGROUND: Little is known about the impact of online health education on multiple sclerosis (MS)-related knowledge and other health outcomes in the MS community. OBJECTIVES: To estimate the impact of participating in a massive open online course (MOOC) about MS on course completer MS-related knowledge, health literacy (HL), self-efficacy, resilience, quality of life, and MS symptom severity. METHODS: In this cohort study, using a single group pre-test/post-test design (n=560), we examined the effects of MOOC participation on MS-related knowledge and other outcomes using a paired t-test. We used regression and structural equation modelling to examine the association between participant characteristics, changes in other outcomes, and changes in MS-related knowledge. RESULTS: We found significant increases in MS-related knowledge for people living with MS (PwMS) (+2.13 points, p<0.001) and those without MS (+5.16 points, p<0.001), with larger effect sizes for those with higher educational levels. Among PwMS, there were also significant increases in seven HL subscales and self-efficacy, but no increase in resilience, MS symptoms severity or quality of life. Among people without MS, there were increases in two HL subscales and quality of life, but no increase in resilience or self-efficacy. Changes in MS-related knowledge were not associated with sex or changes in other study outcomes. CONCLUSIONS: There was a significant increase in MS-related knowledge, which was unrelated to the changes in the other study outcomes, both for PwMS and for those not living with MS. Outcome-specific health educational interventions may be needed to effect change in other health outcomes.

Association between MS-related knowledge, health literacy, self-efficacy, resilience, and quality of life in a large cohort of MS community members: A cross-sectional study.

BACKGROUND: Despite their potential importance, little is known about the associations between multiple sclerosis (MS) knowledge and other outcomes among MS community members. OBJECTIVE: To examine the relationships between MS-related knowledge, health literacy, self-efficacy, resilience, quality of life (QoL), and MS symptom severity in a cohort of MS community members. METHODS: In this cross-sectional study (N = 1993), we assessed a cohort of Understanding MS online course enrolees using means and standard deviations. We evaluated the impact of participant characteristics on outcomes using chi square, t-tests, and linear regression models, and assessed associations between outcomes using Pearson correlation. RESULTS: We found that the total cohort had moderate to high scores on all outcomes. People living with MS had an above average mean MS knowledge score, but below average QoL, resilience, and health literacy scores. The association of MS status with outcome scores was supported by linear regression models. MS knowledge was not correlated with any other outcome for either people living with MS or without MS. CONCLUSIONS: MS knowledge was not associated with the other study outcomes, suggesting that educational interventions that solely aim to increase knowledge may be ineffective in improving health-related outcomes within the MS community.

Work productivity trajectories of Australians living with multiple sclerosis: A group-based modelling approach.

BACKGROUND: Studies have documented reduced work capacity and work productivity loss in multiple sclerosis (MS). Little is known about the longitudinal trajectories of work productivity in MS. OBJECTIVES: To examine trajectories of work productivity in people living with multiple sclerosis (PwMS) and the factors associated with the trajectories. METHODS: Study participants were employed participants of the Australian MS Longitudinal Study (AMSLS) followed from 2015 to 2019 with at least two repeated measures (n=2121). We used group-based trajectory modelling to identify unique work productivity trajectories in PwMS. RESULTS: We identified three distinct trajectories of work productivity: 'moderately reduced' (17.0% of participants) with a mean work productivity level of 47.6% in 2015 (slope -0.97% per year (p= 0.22)), 'mildly reduced' (46.7%) with a mean work productivity of 86.3% in 2015 (slope 0.70% per year (p=0.12)), and 'full' (36.3%) with a mean work productivity of 99.7% in 2015 (slope 0.29% per year (p= 0.30)). Higher education level, higher disability, and higher MS symptom severity are associated with increased probability of being in a worse work productivity trajectory. CONCLUSION: We identified three distinct work productivity trajectories in PwMS which were stable over time and differentiated by their baseline level of work productivity.

Representativeness of the participants in the smoking Cessation in Pregnancy Incentives Trial (CPIT): a cross-sectional study.

BACKGROUND: The limited representativeness of trial samples may restrict external validity. The aim of this study was to ascertain the representativeness of the population enrolled in the Cessation in Pregnancy Incentives Trial (CPIT), a therapeutic exploratory study to examine the effectiveness of financial incentives for smoking cessation during pregnancy. METHODS: CPIT participants (n = 492) were compared with all self-reported smokers at maternity booking who did not participate in the trial (n = 1982). Both groups were drawn from the National Health Service (NHS) Greater Glasgow and Clyde area over a 1-year trial enrolment period. Variables used for comparison were age, area-based deprivation index, body mass index, gestation, and carbon monoxide (CO) breath test level. Chi-square and Mann-Whitney U tests were used to compare groups. RESULTS: From January to December 2012, 2474/13,945 (17.7 %) women, who booked for maternity care, self-reported as current smokers (at least one cigarette in the last week). Seven hundred and fifty-two were ineligible for trial participation because of a CO breath test level of less than 7 parts per million (ppm) used as a biochemical cut-off to corroborate self-report of current smoking. At telephone consent 301 could not be contacted, 11 had miscarried, 16 did not give consent and 3 opted out after randomisation, leaving 492 participants for analysis. There were no differences in demographic or clinical characteristics between trial participants, and self-reported smokers not enrolled in the trial in terms of CO breath test (as a measure of smoking level for those with a CO level of 7 ppm or higher), material deprivation (using an area-based measure), maternal age and maternal body mass index. Gestation at booking was statistically significantly lower for participants. CONCLUSIONS: To ensure that all trial participants were smokers, biochemical validation excluded self-reported smokers with a CO level of less than 7 ppm from taking part in the trial, which excluded 30 % of self-reported smokers who were 'lighter' smokers. The efficacy of financial incentives would not have been likely to decrease if 'lighter' smokers had been included in the trial population. Trial participants were slightly earlier in their pregnancy at maternity booking, but this difference would not clinically affect the provision of financial incentives if provided routinely. Overall, the trial population was representative of all self-reported smokers with regard to available routinely collected data. Appropriate comparison of trial and target populations, with detailed reporting of exclusion criteria would contribute to the understanding of the wider applicability of trial results.
