High adherence to antimalarials and antibiotics under integrated community case management of illness in children less than five years in eastern Uganda.

ABSTRACT: BACKGROUND: Development of resistance to first line antimalarials led to recommendation of artemisinin based combination therapies (ACTs). High adherence to ACTs provided by community health workers (CHWs) gave reassurance that community based interventions did not increase the risk of drug resistance. Integrated community case management of illnesses (ICCM) is now recommended through which children will access both antibiotics and antimalarials from CHWs. Increased number of medicines has been shown to lower adherence. OBJECTIVE: To compare adherence to antimalarials alone versus antimalarials combined with antibiotics under ICCM in children less than five years. METHODS: A cohort study was nested within a cluster randomized trial that had CHWs treating children less than five years with antimalarials and antibiotics (intervention areas) and CHWs treating children with antimalarials only (control areas). Children were consecutively sampled from the CHWs' registers in the control areas (667 children); and intervention areas (323 taking antimalarials only and 266 taking antimalarials plus antibiotics). The sampled children were visited at home on day one and four of treatment seeking. Adherence was assessed using self reports and pill counts. RESULTS: Adherence in the intervention arm to antimalarials alone and antimalarials plus antibiotics arm was similar (mean 99% in both groups) but higher than adherence in the control arm (antimalarials only) (mean 96%). Forgetfulness (38%) was the most cited reason for non-adherence. At adjusted analysis: absence of fever (OR = 3.3, 95%CI =1.6-6.9), seeking care after two or more days (OR = 2.2, 95%CI = 1.3-3.7), not understanding instructions given (OR = 24.5, 95%CI = 2.7-224.5), vomiting (OR = 2.6, 95%CI = 1.2-5.5), and caregivers' perception that the child's illness was not severe (OR = 2.0, 95%CI = 1.1-3.8) were associated with non-adherence. CONCLUSIONS: Addition of antibiotics to antimalarials did not lower adherence. However, caregivers should be adequately counseled to understand the dosing regimens; continue with medicines even when the child seems to improve; and re-administer doses that have been vomited.

Project description:BackgroundStaphylococcus aureus carriage is a known risk factor for staphylococcal disease. However, the carriage rates vary by country, demographic group and profession. This study aimed to determine the S. aureus carriage rate in children in Eastern Uganda, and identify S. aureus lineages that cause infection in Uganda.MethodsNasopharyngeal samples from 742 healthy children less than 5?years residing in the Iganga/Mayuge Health and Demographic Surveillance Site in Eastern Uganda were processed for isolation of S. aureus. Antibiotic susceptibility testing based on minimum inhibitory concentrations (MICs) was determined by the BD Phoenix™ system. Genotyping was performed by spa and SCCmec typing.ResultsThe processed samples yielded 144?S. aureus isolates (one per child) therefore, the S. aureus carriage rate in children was 19.4% (144/742). Thirty one percent (45/144) of the isolates were methicillin resistant (MRSA) yielding a carriage rate of 6.1% (45/742). All isolates were susceptible to rifampicin, vancomycin and linezolid. Moreover, all MRSA were susceptible to vancomycin, linezolid and clindamycin. Compared to methicillin susceptible S. aureus (MSSA) isolates (68.8%, 99/144), MRSA isolates were more resistant to non-beta-lactam antimicrobials -trimethoprim/sulfamethoxazole 73.3% (33/45) vs. 27.3% (27/99) [p?<?0.0001]; erythromycin 75.6% (34/45) vs. 24.2% (24/99) [p?<?0.0001]; chloramphenicol 60% (27/45) vs. 19.2% (19/99) [p?<?0.0001]; gentamicin 55.6% (25/45) vs. 25.3% (25/99) [p?=?0.0004]; and ciprofloxacin 35.6% (16/45) vs. 2% (2/99) [p?<?0.0001]. Furthermore, 42 MRSA (93.3%) were multidrug resistant (MDR) and one exhibited high-level resistance to mupirocin. Overall, 61 MSSA (61.6%) were MDR, including three mupirocin and clindamycin resistant isolates. Seven spa types were detected among MRSA, of which t037 and t064 were predominant and associated with SCCmec types I and IV, respectively. Fourteen spa types were detected in MSSA which consisted mainly of t645 and t4353.ConclusionsS. aureus carriage rate in healthy children in Eastern Uganda is high and comparable to rates for hospitalized patients in Kampala. The detection of mupirocin resistance is worrying as it could rapidly increase if mupirocin is administered in a low-income setting. S. aureus strains of spa types t064, t037 (MRSA) and t645, t4353 (MSSA) are prevalent and could be responsible for majority of staphylococcal infections in Uganda.

Project description:BACKGROUND:Adherence to Antiretroviral Therapy (ART) is required to achieve HIV viral load suppression. However, children under 5 years in Jinja, Uganda, had been shown to have low HIV suppression rates. This study aimed to determine the level of ART non-adherence among these children and the associated factors. METHODS:Data for the cross-sectional study was collected from April to July 2019, from caregivers of 206 children under 5 years living with HIV who were attending health facilities in Jinja and had been on ART for at least 3 months. Non-adherence was measured using a Visual Analog Scale that assessed both dosing and timing non-adherence, and by determining the Proportion of Days Covered by the medication. A questionnaire administered to the caregivers was used to collect the data, together with medical record review. A child was only considered adherent if they had adherence greater than 95% on all the measures. The data was analysed using Modified Poisson Regression, taking a p-value less than 0.05 as statistically significant. RESULTS:Of the 206 children, 73.8% were older than 2?years, and 52.9% were female. Likewise, the majority of caregivers were female (93.7%). Using the combined adherence measure, 57.3% of the children were categorised as non-adherent. School/day-care attendance, Prevalence Ratio (PR)?=?1.25 (p?=?0.042), the caregiver having higher than a primary school education, PR?=?0.72 (p?=?0.044) and satisfaction with the quality of service at the health facility, PR?=?0.97 (p?<?0.001) were associated with non-adherence. Household food insecurity was also associated with non-adherence: PR?=?1.55 (p?=?0.011) for mild food insecurity, PR?=?1.75 (p?=?0.001) for moderate insecurity and PR?=?1.48 (p?=?0.015) for severe food insecurity. CONCLUSIONS:Children under 5 years in Jinja had a high level of ART non-adherence. It is important to engage schools to support adherence among children living with HIV. Addressing household food insecurity and improving the quality of paediatric ART services would also reduce the barriers to optimal adherence.

Project description:BACKGROUND: Curative interventions delivered by community health workers (CHWs) were introduced to increase access to health services for children less than five years and have previously targeted single illnesses. However, CHWs in the integrated community case management of childhood illnesses strategy adopted in Uganda in 2010 will manage multiple illnesses. There is little documentation about the performance of CHWs in the management of multiple illnesses. This study compared the performance of CHWs managing malaria and pneumonia with performance of CHWs managing malaria alone in eastern Uganda and the factors influencing performance. METHODS: A mixed methods study was conducted among 125 CHWs providing either dual malaria and pneumonia management or malaria management alone for children aged four to 59 months. Performance was assessed using knowledge tests, case scenarios of sick children, review of CHWs' registers, and observation of CHWs in the dual management arm assessing respiratory symptoms. Four focus group discussions with CHWs were also conducted. RESULTS: CHWs in the dual- and single-illness management arms had similar performance with respect to: overall knowledge of malaria (dual 72%, single 70%); eliciting malaria signs and symptoms (50% in both groups); prescribing anti-malarials based on case scenarios (82% dual, 80% single); and correct prescription of anti-malarials from record reviews (dual 99%, single 100%). In the dual-illness arm, scores for malaria and pneumonia differed on overall knowledge (72% vs 40%, p < 0.001); and correct doses of medicines from records (100% vs 96%, p < 0.001). According to records, 82% of the children with fast breathing had received an antibiotic. From observations 49% of CHWs counted respiratory rates within five breaths of the physician (gold standard) and 75% correctly classified the children. The factors perceived to influence CHWs' performance were: community support and confidence, continued training, availability of drugs and other necessary supplies, and cooperation from formal health workers. CONCLUSION: CHWs providing dual-illness management handled malaria cases as well as CHWs providing single-illness management, and also performed reasonably well in the management of pneumonia. With appropriate training that emphasizes pneumonia assessment, adequate supervision, and provision of drugs and necessary supplies, CHWs can provide integrated treatment for malaria and pneumonia.

Project description:Tororo District, Uganda experienced a dramatic decrease in malaria burden from 2015-19 during 5 years of indoor residual spraying (IRS) with carbamate (Bendiocarb) and then organophosphate (Actellic) insecticides. However, a marked resurgence occurred in 2020, which coincided with a change to a clothianidin-based IRS formulations (Fludora Fusion/SumiShield). To quantify the magnitude of the resurgence, investigate causes, and evaluate the impact of a shift back to IRS with Actellic in 2023, we assessed changes in malaria metrics in regions within and near Tororo District. Malaria surveillance data from Nagongera Health Center, Tororo District was included from 2011-2023. In addition, a cohort of 667 residents from 84 houses was followed from August 2020 through September 2023 from an area bordering Tororo and neighboring Busia District, where IRS has never been implemented. Cohort participants underwent passive surveillance for clinical malaria and active surveillance for parasitemia every 28 days. Mosquitoes were collected in cohort households every 2 weeks using CDC light traps. Female Anopheles were speciated and tested for sporozoites and phenotypic insecticide resistance. Temporal comparisons of malaria metrics were stratified by geographic regions. At Nagongera Health Center average monthly malaria cases varied from 419 prior to implementation of IRS; to 56 after 5 years of IRS with Bendiocarb and Actellic; to 1591 after the change in IRS to Fludora Fusion/SumiShield; to 155 after a change back to Actellic. Among cohort participants living away from the border in Tororo, malaria incidence increased over 8-fold (0.36 vs. 2.97 episodes per person year, p<0.0001) and parasite prevalence increased over 4-fold (17% vs. 70%, p<0.0001) from 2021 to 2022 when Fludora Fusion/SumiShield was used. Incidence decreased almost 5-fold (2.97 vs. 0.70, p<0.0001) and prevalence decreased by 39% (70% vs. 43%, p<0.0001) after shifting back to Actellic. There was a similar pattern among those living near the border in Tororo, with increased incidence between 2021 and 2022 (0.93 vs. 2.40, p<0.0001) followed by a decrease after the change to Actellic (2.40 vs. 1.33, p<0.001). Among residents of Busia, malaria incidence did not change significantly over the 3 years of observation. Malaria resurgence in Tororo was temporally correlated with the replacement of An. gambiae s.s. by An. funestus as the primary vector, with a marked decrease in the density of An. funestus following the shift back to IRS with Actellic. In Busia, An. gambiae s.s. remained the primary vector throughout the observation period. Sporozoite rates were approximately 50% higher among An. funestus compared to the other common malaria vectors. Insecticide resistance phenotyping of An. funestus revealed high tolerance to clothianidin, but full susceptibility to Actellic. A dramatic resurgence of malaria in Tororo was temporally associated with a change to clothianidin-based IRS formulations and emergence of An. funestus as the predominant vector. Malaria decreased after a shift back to IRS with Actellic. This study highlights the ability of malaria vectors to rapidly circumvent control efforts and the importance of high-quality surveillance systems to assess the impact of malaria control interventions and generate timely, actionable data.

Project description:ObjectiveTo assess the extent to which Integrated Management of Childhood Illness (IMCI) has been adopted and scaled up in countries.SettingThe 95 countries that participated in the survey are home to 82% of the global under-five population and account for 95% of the 5.9?million deaths that occurred among children less than 5?years of age in 2015; 93 of them are low-income and middle-income countries (LMICs).MethodsWe conducted a cross-sectional self-administered survey. Questionnaires and data analysis focused on (1) giving a general overview of current organisation and financing of IMCI at country level, (2) describing implementation of IMCI's three original components and (3) reporting on innovations, barriers and opportunities for expanding access to care for children. A single data file was created using all information collected. Analysis was performed using STATA V.11.ParticipantsIn-country teams consisting of representatives of the ministry of health and country offices of WHO and Unicef.ResultsEighty-one per cent of countries reported that IMCI implementation encompassed all three components. Almost half (46%; 44 countries) reported implementation in 90% or more districts as well as all three components in place (full implementation). These full-implementer countries were 3.6 (95% CI 1.5 to 8.9) times more likely to achieve Millennium Development Goal 4 than other (not full implementer) countries. Despite these high reported implementation rates, the strategy is not reaching the children who need it most, as implementation is lowest in high mortality countries (39%; 7/18).ConclusionThis survey provides a unique opportunity to better understand how implementation of IMCI has evolved in the 20 years since its inception. Results can be used to assist in formulating strategies, policies and activities to support improvements in the health and survival of children and to help achieve the health-related, post-2015 Sustainable Development Goals.

Project description:BackgroundThe Strategy of the Integrated Management of Childhood Illness (IMCI) was introduced in Central Asia and Europe to address the absence of evidence-based guidelines, the misuse of antibiotics, polypharmacy and over-hospitalization of children. A study carried out in 16 countries analysed the status and strengths of as well as the barriers to IMCI implementation and investigated how different health systems affect the problems IMCI aims to address. Here we present findings in relation to IMCI's effects on the rational use of drugs, particularly the improved rational use of antibiotics in children, the mechanisms through which these were achieved as well as counteracting system factors.Methods220 key informants were interviewed ranging from 5 to 37 per country (median 12). Data was analysed for arising themes and peer-reviewed.ResultsThe implementation of IMCI led to improved prescribing patterns immediately after training of health workers according to key informants. IMCI provides standard treatment guidelines and an algorithmic diagnostic- and treatment-decision-tool for consistent decision-making. Doctors reported feeling empowered by the training to counsel parents and address their expectations and desire for invasive treatments and the use of multiple drugs. Improved prescribing patterns were not sustained over time but counteracted by factors such as: doctors prescribing antibiotics to create additional revenues or other benefits; aggressive marketing by pharmaceutical companies; parents pressuring doctors to prescribe antibiotics; and access to drugs without prescriptions.ConclusionsFuture efforts to improve child health outcomes must include: (1) the continued support to improve health worker performance to enable them to adhere to evidence-based treatment guidelines, (2) patient and parent education, (3) improved reimbursement schemes and prescription regulations and their consistent enforcement and (4) the integration of point-of-care tests differentiating between viral and bacterial infection into standards of care. Pre-requisites will be sufficient remuneration of health workers, sound training, improved health literacy among parents, conducive laws and regulations and reimbursement systems with adequate checks and balances to ensure the best possible care.

Project description:In June 2015, a malaria epidemic was confirmed in ten districts of Northern Uganda; after cessation of indoor residual spraying (IRS). Epidemic was defined as an increase in incidence per month beyond one standard deviation above mean incidence of previous 5 years. Trends in malaria incidence among children-under-5-years were analysed so as to describe the extent of change in incidence prior to and after cessation of IRS.Secondary data on out-patient malaria case numbers for children-under-5-years July 2012 to June 2015 was electronically extracted from the district health management information software2 (DHIS2) for ten districts that had IRS and ten control districts that didn't have IRS. Data was adjusted by reporting rates, cleaned by smoothing and interpolation and incidence of malaria per 1000 population derived. Population data obtained from 2002 and 2014 census reports. Data on interventions obtained from malaria programme reports, rainfall data obtained from Uganda National Meteorological Authority. Three groups of districts were created; two based on when IRS ended, the third not having IRS. Line graphs were plotted showing malaria incidence vis-à-vis implementation of IRS, mass net distribution and rainfall. Changes in incidence after withdrawal of IRS were obtained using incidence rate ratios (IRR). IRR was calculated as incidence for each month after the last IRS divided by incidence of the IRS month. Poisson regression was used to test statistical significance.Incidence of malaria declined between spray activities in districts that had IRS. Decline in IRR for 4 months after last IRS month was greater in the sprayed than control districts. On the seventh month following cessation of IRS, incidence in sprayed districts rose above that of the last spray month [1.74: 95% CI (1.40-2.15); and 1.26: 95% CI (1.05-1.51)]. Rise in IRR continued from 1.26 to 2.62 (95% CI 2.21-3.12) in June 2015 for districts that ended IRS in April 2014. Peak in rainfall occurred in May 2015.There was sustained control of malaria incidence during IRS implementation. Following withdrawal and peak in rainfall, incidence rose to epidemic proportions. This suggests a plausible link between the malaria epidemic, peak in rainfall and cessation of IRS.
