Community engagement to inform the development of a sickle cell counselor training and certification program in Ghana

Sickle cell disease (SCD) and sickle cell trait (SCT) are highly prevalent in Africa. Despite public health implications, there is limited understanding of community issues for implementing newborn screening and appropriate family counseling. We conducted a 3-day workshop in Kumasi, Ghana, with community leaders as lay program development advisors to assist the development and implementation of a Sickle Cell Counselor Training and Certification Program. We employed qualitative methods to understand cultural, religious, and psychosocial dimensions of SCD and SCT, including the advisors’ attitudes and beliefs in relation to developing a culturally sensitive approach to family education and counseling that is maximally suited to diverse communities in Ghana. We collated advisors’ discussions and observations in order to understand community issues and potential challenges and guide strategies for advocacy in SCD family education and counseling. Results from the workshop revealed that community leaders representing diverse communities in Ghana were engaged constructively in discussions about developing a culturally sensitive counselor training program. Key findings included the importance of improved knowledge about SCD among the public and youth in particular, the value of stakeholders such as elders and religious and traditional leaders, and government expectations of reduced SCD births. We submitted a report to the Ministry of Health in Ghana with recommendations for the next steps in developing a national sickle cell counselor training program. We named the program “Genetic Education and Counseling for Sickle Cell Conditions in Ghana” (GENECIS-Ghana). The first GENECIS-Ghana Training and Certification Program Workshop was conducted from June 8 to 12, 2015

Does health status explain gender dissimilarity in healthcare use among older adults? Estado de saúde explica a disparidade entre mulheres e homens idosos no uso da assistência?

This study investigates the extent to which gender dissimilarity in healthcare use in later life is explained by variation in health and social-economic statuses. It is based on a nationwide sample in Brazil of 12,757 men and 16,186 women aged 60+ years. Individuals with great difficulties or unable to perform at least one daily living activity and/or to walk 100m were classified as "established disability". Those who had interrupted their activities in the previous 15 days because of a health problem were regarded as "temporarily disabled". The remaining we classified as "healthy". These categories were analyzed by multinomial logistic regression, taking "healthy" as the reference category. Prevalences of established disability were 6% among men and 11% among women. Temporary disabilities were 7.9% and 10.1%, respectively. Poor health status was associated with increased use of healthcare among men and women, but men and women differed significantly in relation to use pattern after adjustment for age, health status, and income. Older women were greater consumers of outpatient services and older men of inpatient care.<br>O presente trabalho investiga diferenciais de gênero na condição de saúde de idosos e examina se desigualdades de gênero na utilização de serviços de saúde são explicadas pela condição de saúde ou sócio-econômica dos mesmos. Foram estudados 12.725 homens e 16.186 mulheres com 60+ anos, participantes da PNAD 1998. Idosos com grande dificuldade/incapazes de realizar uma/mais atividades da vida diária e/ou andar mais de 100m foram classificados como incapacitados, aqueles que interromperam atividades nos últimos 15 dias por problemas de saúde, como temporariamente incapacitados, e demais, como saudáveis. Utilizou-se regressão logística multinomial (referência: indivíduos saudáveis). A prevalência de homens e mulheres incapacitados foi 6% e 11%, temporariamente incapacitados, 7,9% e 10,1% respectivamente. Pior condição de saúde está associada ao maior uso serviços de saúde, mas padrão de utilização é significativamente diferente entre ambos, independente da idade, condição de saúde ou nível de renda. Idosas apresentaram mais consulta médica, e idosos, mais internações. Identificamos diferenciais de gênero no padrão de utilização de serviços de saúde que não são explicados pela idade, condição de saúde ou sócio-econômica

Patient reports of health outcome for adults living with sickle cell disease: development and testing of the ASCQ-Me item banks

BACKGROUND: Providers and patients have called for improved understanding of the health care requirements of adults with sickle cell disease (SCD) and have identified the need for a systematic, reliable and valid method to document the patient-reported outcomes (PRO) of adult SCD care. To address this need, the Adult Sickle Cell Quality of Life Measurement System (ASCQ-Me) was designed to complement the Patient Reported Outcome Measurement Information System (PROMIS®). Here we describe methods and results of the psychometric evaluation of ASCQ-Me item banks (IBs). METHODS: At seven geographically-disbursed clinics within the US, 556 patients responded to questions generated to assess cognitive, emotional, physical and social impacts of SCD. We evaluated the construct validity of the hypothesized domains using exploratory factor analysis (EFA), parallel analysis (PA), and bi-factor analysis (Item Response Theory Graded Response Model, IRT-GRM). We used IRT-GRM and the Wald method to identify bias in responses across gender and age. We used IRT and Cronbach’s alpha coefficient to evaluate the reliability of the IBs and then tested the ability of summary scores based on IRT calibrations to discriminate among tertiles of respondents defined by SCD severity. RESULTS: Of the original 140 questions tested, we eliminated 48 that either did not form clean factors or provided biased measurement across subgroups defined by age and gender. Via EFA and PA, we identified three subfactors within physical impact: sleep, pain and stiffness impacts. Analysis of the resulting six item sets (sleep, pain, stiffness, cognitive, emotional and social impacts of SCD) supported their essential unidimensionality. With the exception of the cognitive impact IB, these item sets also were highly reliable across a broad range of values and highly significantly related to SCD disease severity. CONCLUSION: ASCQ-Me pain, sleep, stiffness, emotional and social SCD impact IBs demonstrated exceptional measurement properties using modern and classical psychometric methods of evaluation. Further development of the cognitive impact IB is required to improve its sensitivity to differences in SCD disease severity. Future research will evaluate the sensitivity of the ASCQ-Me IBs to change in SCD disease severity over time due to health interventions
