Project description:Background: This proof-of-concept trial examined a 6-month Prevention Plus (PP) intervention implemented in a federally qualified health center on child standardized BMI (ZBMI), using a planned clinical effect threshold of -0.16 ZBMI. The relationship between food security status and PP delivered with caregiver goals (PP+) and without caregiver goals (PP-) on energy balance behaviors (i.e., fruits and vegetables, physical activity) and child ZBMI was explored. Methods: Seventy-three, underserved children, 4-10 years of age with a BMI ≥85th percentile, were randomized to one of two interventions, PP+ and PP-, both providing 2.5 hours of contact time, implemented in five clinics by behavioral health consultants (BHCs). Outcomes were child anthropometrics (included 9-month follow-up), implementation data collected from electronic health records, and caregiver and BHC evaluations. Results: Children were 57.5% female and 78.1% Hispanic, with 32.9% from food-insecure households and 58.9% from households with an annual income of less than $20,000. Child ZBMI significantly (p < 0.05) decreased at 6 and 9 months (-0.08 ± 0.24 and -0.12 ± 0.43), with only PP+ reaching the clinical threshold at 9 months (PP+: -0.20 ± 0.42 vs. PP-: -0.05 ± 0.42). Sixty-four percent of families attended ≥50% of the sessions, and BHCs delivered 78.5% ± 23.5% of components at attended sessions. Caregivers were satisfied with the intervention and BHCs found the intervention helpful/useful. No relationship with food insecurity status and outcomes was found. Conclusions: PP+ when delivered by a primary care provider to underserved families showed promise for producing a clinically meaningful effect. Families and providers felt the intervention was a viable treatment option.

Project description:BackgroundSickle cell disease is highly prevalent in sub-Saharan Africa, where it accounts for substantial morbidity and mortality. Newborn screening is paramount for early diagnosis and enrolment of affected children into a comprehensive care programme. Up to now, this strategy has been greatly impaired in resource-poor countries, because screening methods are technologically and financially intensive; affordable, reliable, and accurate methods are needed. We aimed to test the feasibility of implementing a sickle cell disease screening programme using innovative point-of-care test devices into existing immunisation programmes in primary health-care settings.MethodsBuilding on a routine immunisation programme and using existing facilities and staff, we did a prospective feasibility study at five primary health-care centres within Gwagwalada Area Council, Abuja, Nigeria. We systematically screened for sickle cell disease consecutive newborn babies and infants younger than 9 months who presented to immunisation clinics at these five centres, using an ELISA-based point-of care test (HemoTypeSC). A subgroup of consecutive babies who presented to immunisation clinics at the primary health-care centres, whose mothers gave consent, were tested by the HemoTypeSC point-of-care test alongside a different immunoassay-based point-of-care test (SickleSCAN) and the gold standard test, high-performance liquid chromatography (HPLC).FindingsBetween July 14, 2017, and Sept 3, 2019, 3603 newborn babies and infants who presented for immunisation were screened for sickle cell disease at five primary health-care centres using the ELISA-based point-of-care test. We identified 51 (1%) children with sickle cell anaemia (HbSS), four (<1%) heterozygous for HbS and HbC (HbSC), 740 (21%) with sickle cell trait (HbAS), 34 (1%) heterozygous for HbA and HbC (HbAC), and 2774 (77%) with normal haemoglobin (HbAA). Of the 55 babies and infants with confirmed sickle cell disease, 41 (75%) were enrolled into a programme for free folic acid and penicillin, of whom 36 (88%) completed three visits over 9 months (median follow-up 226 days [IQR 198-357]). The head-to-head comparison between the two point-of-care tests and HPLC showed concordance between the three testing methods in screening 313 newborn babies, with a specificity of 100% with HemoTypeSC, 100% with SickleSCAN, and 100% by HPLC, and a sensitivity of 100% with HemoTypeSC, 100% with SickleSCAN, and 100% by HPLC.InterpretationOur pilot study shows that the integration of newborn screening into existing primary health-care immunisation programmes is feasible and can rapidly be implemented with limited resources. Point-of-care tests are reliable and accurate in newborn screening for sickle cell disease. This feasibility study bodes well for the care of patients with sickle cell disease in resource-poor countries.FundingDoris Duke Charitable Foundation, Imperial College London Wellcome Trust Centre for Global Health Research, and Richard and Susan Kiphart Family Foundation.

Project description:We used the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework to evaluate a Stroke Prevention Team's readiness to prevent strokes in children with sickle cell anemia living in northern Nigeria. The NIH sponsored Stroke Prevention Trial in Nigeria included a goal of a sustainable stroke prevention program. The program's 1-year reach for transcranial Doppler screening was 14.7% (4710/32,000) of which 6.0% (281/4710) had abnormal velocities (≥200 cm/s). All participants with abnormal transcranial Doppler velocities were started on hydroxyurea (effectiveness). The leaders of all 5 hospitals agreed to adopt the program. After 1 year, program-implementation and maintenance rates were 100%, demonstrating the program's feasibility and short-term sustainability.

Project description:BACKGROUND: Although many residency programs are instituting quality improvement (QI) curricula in response to both institutional and external mandates, there are few reports of successful integration of resident initiated projects into these QI curricula with documented impact on health care processes and measures. INTERVENTION: We introduced a multifaceted curriculum into an Obstetrics-Gynecology continuity clinic. Following a needs assessment, we developed a didactic session to introduce residents to QI tools and the how to of a mentored resident-initiated project. Resident projects were presented to peers and faculty and were evaluated. A postgraduation survey assessed residents' satisfaction with the curriculum and preparedness for involvement in QI initiatives after residency. We also assessed whether this resulted in sustained improvement in health care measures. RESULTS: The curriculum was presented to 7 classes of residents (n = 25) and 17 resident initiated projects have been completed. Twenty-one residents (84%) completed the preintervention survey and 12 of 17 (71%) residents who completed the entire curriculum completed the postintervention survey. Sustained change in surrogate health measures was documented for 4 projects focused on improving clinical measures, and improvement in clinical systems was sustained in 9 of the remaining 13 projects (69%). Most of the respondents (75%, n = 9) agreed or strongly agreed that the projects done in residency provided a helpful foundation to their current QI efforts. CONCLUSION: This project successfully demonstrates that a multifaceted program in QI education can be implemented in a busy Obstetrics-Gynecology residency program, resulting in sustained improvement in surrogate health measures and in clinical systems. A longitudinal model for resident projects results in an opportunity for reflection, project revision, and a maintenance plan for continued clinical impact.

Project description:The vast majority of children with sickle cell anemia (SCA) live in Africa, where evidence-based guidelines for primary stroke prevention are lacking. In Kano, Nigeria, we conducted a feasibility trial to determine the acceptability of hydroxyurea therapy for primary stroke prevention in children with abnormal transcranial Doppler (TCD) measurements. Children with SCA and abnormal non-imaging TCD measurements (≥200 cm/s) received moderate fixed-dose hydroxyurea therapy (∼20 mg/kg/day). A comparison group of children with TCD measurements <200 cm/s was followed prospectively. Approximately 88% (330 of 375) of families agreed to be screened, while 87% (29 of 33) of those with abnormal TCD measurements, enrolled in the trial. No participant elected to withdraw from the trial. The average mean corpuscular volume increased from 85.7 fl at baseline to 95.5 fl at 24 months (not all of the children who crossed over had a 24 month visit), demonstrating adherence to hydroxyurea. The comparison group consisted of initially 210 children, of which four developed abnormal TCD measurements, and were started on hydroxyurea. None of the monthly research visits were missed (n = total 603 visits). Two and 10 deaths occurred in the treatment and comparison groups, with mortality rates of 2.69 and 1.81 per 100 patient-years, respectively (P = .67). Our results provide strong evidence, for high family recruitment, retention, and adherence rates, to undertake the first randomized controlled trial with hydroxyurea therapy for primary stroke prevention in children with SCA living in Africa.

Project description:We tested the hypothesis that fixed oral moderate-dose hydroxyurea (20 mg/kg per day) for initial treatment of secondary stroke prevention results in an 80% relative risk reduction of stroke or death when compared with fixed oral low-dose hydroxyurea (10 mg/kg per day) in a phase 3 double-blind, parallel-group, randomized controlled trial in children with sickle cell anemia (SCA) living in Nigeria. A total of 101 participants were randomly allocated to low-dose (n = 49) and moderate-dose (n = 52) hydroxyurea treatment groups. The median participant follow-up was 1.6 years (interquartile range, 1.0-2.3), with a planned minimum follow-up of 3.0 years. A total of 6 recurrent strokes and 2 deaths vs 5 recurrent strokes and 3 deaths occurred in the low- and moderate-dose groups, respectively. The incidence rate ratio (IRR) of the primary outcome measure of stroke or death in the low- and moderate-dose hydroxyurea treatment groups was 0.98 (95% confidence interval [CI], 0.32-3.00; P = .97). The trial was stopped early owing to no clinical difference in the incidence rates of the primary outcome measure. The incidence rates of recurrent strokes were 7.1 and 6.0 per 100 person-years in the low- and moderate-dose groups, respectively, (IRR, 1.18; 95% CI, 0.30-4.88; P = .74). As a measure of adherence to the oral hydroxyurea therapy, the median percent of returned pills was 3.0% and 2.6% in the low- and moderate-dose groups, respectively. No participant had hydroxyurea therapy stopped for myelosuppression. For children with SCA in low-income settings without access to regular blood transfusion therapy, initial low-dose hydroxyurea is a minimum known efficacious dose for secondary stroke prevention.

Project description:BackgroundHidden hunger (micronutrient deficiencies) among adolescents are linked to impaired physical growth, poor cognitive function, low resistance to infection as well as degenerative and chronic diseases at later age. To prevent these deleterious impacts of hidden hunger, effective intervention strategy that improves nutrition knowledge and promotes healthy food choices among this age-group becomes imperative. The intervention was to evaluate the impact of a 14-page locally developed nutrition education aids on the teenagers' knowledge of the functions, food sources and deficiencies of some micronutrients and their food choices.MethodsA one group pre-and post-intervention quasi-experimental study design was conducted with 869 adolescents (13-17 years) selected using multi-stage sampling technique in public secondary schools in a suburb of Nigeria. Using the instructional material development guidelines, the nutrition education aids were developed with nutrition facts, pictures of staple micronutrients-rich foods, and computer graphics. Baseline (pre-intervention) knowledge of nutrition and practice of food choices in relation to micronutrients were determined before exposing the students to the developed nutrition education aids and reassessing (post-intervention) them after 6 months. Data obtained were subjected to paired samples t-test using SPSS version 21.ResultsThe adolescents were mostly females (58.92%) aged 16-17 years (53.62%). There was significantly (p < 0.05) higher mean knowledge scores of general nutrition (65.77 vs. 39.61%) and food sources of nutrients (82.26 vs. 66.87%) at post-intervention compared to pre-intervention. Also, the mean knowledge of functions and deficiencies of vitamin C, folic acid, iron, calcium, and zinc were significantly (p < 0.05) higher at post-intervention than at pre-intervention. The study further revealed percentage increase in the proportion of respondents who consumed meat (27.72%), mango (128.20%), watermelon (152.29%), carrot (336.34%) and leafy vegetables (85.56%) daily after the intervention. In addition, the percentage of students who rarely consumed all the studied micronutrient-rich foods decreased after the intervention.ConclusionThe intervention strategy increased the nutrition knowledge and the consumption of some micronutrients-rich food sources among the adolescents. The developed nutrition education aids are recommended for use in the fight to reduce/eradicate hidden hunger among adolescents in Nigeria.

Project description:PurposeWithin a medical clinic environment, pediatric obesity prevention education for families faces challenges. Existing long-term government-funded nutrition education programs have the expertise and staff to deliver. The purpose is to determine feasibility of colocating the Expanded Food and Nutrition Education Program (EFNEP) into a medical clinic setting to support pediatric obesity prevention.MethodsPhysicians from a large university teaching and research hospital (n = 73) and 4 small Medicaid-serving community clinics (n = 18) in the same geographic area in northern California were recruited and trained in the patient-referral protocol for a primary prevention intervention provided by EFNEP. The 8-week intervention deployed in the medical clinics, included general nutrition, physical activity and parenting topics anchored with guided goal setting and motivational modeling. Referral, enrollment, and attendance data were collected for 2 years. Parent and physician feasibility surveys, parent interviews and parent risk assessment tools were administered. Paired-sample t-test analysis was conducted.ResultsTwenty intervention series with parents of patients (n = 106) were conducted at 5 clinics. Physicians (n = 92) generated 686 referrals. Every 6 referrals generated 1 enrolled parent. Physicians (91%, n = 34) reported the intervention as useful to families. Parents (n = 82) reported improved child behaviors for sleep, screen time, physical activity, and food and beverage offerings (P < .0001) and at family mealtime (P < .001). Focus group interviews (n = 26) with 65 participants indicated that parents (97%) reacted positively to participating in the intervention with about a third indicating the classes were relevant to their needs.ConclusionThe intervention is a feasible strategy for the 5 medical clinics. Physicians referred and parents enrolled in the intervention with both physicians and parents indicating positive benefits. Feasibility is contingent upon physician awareness of the intervention and motivation to refer patients and additional EFNEP and clinic staff time to enroll and keep parents engaged.

Project description:BackgroundFalls in hospital remain a common and costly patient safety issue internationally. There is evidence that falls in hospitals can be prevented by multifactorial programs and by education for patients and staff, but these are often not routinely or effectively implemented in practice. Perspectives of multiple key stakeholder groups could inform implementation of fall prevention strategies.MethodsClinicians of different disciplines, patients and their families were recruited from wards at two acute public hospitals. Semi-structured interviews and focus groups were conducted to gain a broad understanding of participants' perspectives about implementing fall prevention programs. Data were analysed using an inductive thematic approach.ResultsData from 50 participants revealed three key themes across the stakeholder groups shaping implementation of acute hospital fall prevention programs: (i) 'Fall prevention is a priority, but whose?' where participants agreed falls in hospital should be addressed but did not necessarily see themselves as responsible for this; (ii) 'Disempowered stakeholders' where participants expressed feeling frustrated and powerless with fall prevention in acute hospital settings; and (iii) 'Shared responsibility may be a solution' where participants were optimistic about the positive impact of collective action on effectively implementing fall prevention strategies.ConclusionKey stakeholder groups agree that hospital fall prevention is a priority, however, challenges related to role perception, competing priorities, workforce pressure and disempowerment mean fall prevention may often be neglected in practice. Improving shared responsibility for fall prevention implementation across disciplines, organisational levels and patients, family and staff may help overcome this.
