Multiple behaviour change intervention for diarrhoea control in Lusaka, Zambia: a cluster randomised trial

Background Eff ective prevention and control of diarrhoea requires caregivers to comply with a suite of proven measures, including exclusive breastfeeding, handwashing with soap, correct use of oral rehydration salts, and zinc administration. We aimed to assess the eff ect of a novel behaviour change intervention using emotional drivers on caregiver practice of these behaviours. Methods We did a cluster randomised controlled trial in Lusaka Province, Zambia. A random sample of 16 health centres (clusters) were selected from a sampling frame of 81 health centres in three of four districts in Lusaka Province using a computerised random number generator. Each cluster was randomly assigned 1:1 to either the intervention— clinic events, community events, and radio messaging—or to a standard care control arm, both for 6 months. Primary outcomes were exclusive breastfeeding (self-report), handwashing with soap (observation), oral rehydration salt solution preparation (demonstration), and zinc use in diarrhoea treatment (self-report). We measured outcome behaviours at baseline before start of intervention and 4–6 weeks post-intervention through repeat cross-sectional surveys with mothers of an infant younger than 6 months and primary caregivers of a child younger than 5 years with recent diarrhoea. We compared outcomes on an intention-to-treat population between intervention and control groups adjusted for baseline behaviour. The study was registered with ClinicalTrials.gov, number NCT02081521. Findings Between Jan 20 and Feb 3, 2014, we recruited 306 mothers of an infant aged 0–5 months (156 intervention, 150 standard care) and 343 primary caregiver of a child aged 0–59 months with recent diarrhoea (176 intervention, 167 standard care) at baseline. Between Oct 20 to Nov 7, 2014, we recruited 401 mothers of an infant 0–5 months (234 intervention, 167 standard care) and 410 primary caregivers of a child 0–59 months with recent diarrhoea (257 intervention, 163 standard care) at endline. Intervention was associated with increased prevalence of self-reported exclusive breastfeeding of infants aged 0–5 months (adjusted diff erence 10·5%, 95% CI 0·9–19·9). Other primary outcomes were not aff ected by intervention. Cluster intervention exposure ranged from 11–81%, measured by participant self-report with verifi cation questions. Comparison of control and intervention clusters with coverage greater than 35% provided strong evidence of an intervention eff ect on oral rehydration salt solution preparation and breastfeeding outcomes. Interpretation The intervention may have improved exclusive breastfeeding (assessed by self-reporting), but intervention eff ects were diluted in clusters with low exposure. Complex caregiver practices can improve through interventions built around human motives, but these must be implemented more intensely

Nano-biomimetic drug delivery vehicles: potential approaches for COVID-19 treatment

The current COVID-19 pandemic has tested the resolve of the global community with more than 35 million infections worldwide and numbers increasing with no cure or vaccine available to date. Nanomedicines have an advantage of providing enhanced permeability and retention and have been extensively studied as targeted drug delivery strategies for the treatment of different disease. The role of monocytes, erythrocytes, thrombocytes, and macrophages in diseases, including infectious and inflammatory diseases, cancer, and atherosclerosis, are better understood and have resulted in improved strategies for targeting and in some instances mimicking these cell types to improve therapeutic outcomes. Consequently, these primary cell types can be exploited for the purposes of serving as a “Trojan horse” for targeted delivery to identified organs and sites of inflammation. State of the art and potential utilization of nanocarriers such as nanospheres/nanocapsules, nanocrystals, liposomes, solid lipid nanoparticles/nano-structured lipid carriers, dendrimers, and nanosponges for biomimicry and/or targeted delivery of bioactives to cells are reported herein and their potential use in the treatment of COVID-19 infections discussed. Physicochemical properties, viz., hydrophilicity, particle shape, surface charge, composition, concentration, the use of different target-specific ligands on the surface of carriers, and the impact on carrier efficacy and specificity are also discussed

Interviewing adolescent girls about sexual and reproductive health: a qualitative study exploring how best to ask questions in structured follow-up interviews in a randomized controlled trial in Zambia

Background Numerous studies have documented inconsistent reporting of sexual behaviour by adolescents. The validity and reliability of self-reported data on issues considered sensitive, incriminating or embarrassing, is prone to social-desirability bias. Some studies have found that Audio Computer-Assisted Self Interviewing (ACASI) that removes the personal interaction involved in face-to-face interviews, decreases item non-response and increases reporting of sensitive behaviours, but others have found inconsistent or contradictory results. To reduce social desirability bias in the reporting of sensitive behaviours, face-to-face interviews were combined with ACASI in a cluster randomized trial involving adolescents in Zambia. Methods To explore adolescent girls’ experiences and opinions of being interviewed about sexual and reproductive health, we combined Focus Group Discussions with girl participants and individual semi-structured interviews with teachers. This study was done after the participants had been interviewed for the 6th time since recruitment. Young, female research assistants who had conducted interviews for the trial were also interviewed for this study. Results Respondents explained often feeling shy, embarrassed or uncomfortable when asked questions about sex, pregnancy and abortion face-to-face. Questions on sexual activity elicited feelings of shame, and teachers, research assistants and girls alike noted that direct questions about sexual activities limit what the participant girls may be willing to share. Responding to more indirect questions in relation to the context of a romantic relationship was slightly easier. Efforts by interviewers to signal that they did not judge the participants for their behavior and increased familiarity with the interviewer reduced discomfort over time. Although some appreciated the opportunity to respond to questions on their own, the privacy offered by ACASI also provided an opportunity to give false answers. Answering on tablets could be challenging, but participants were reluctant to ask for assistance for fear of being judged as not conversant with technology. Conclusion Strategies to avoid using overly direct language and descriptive words, asking questions within the context of a romantic relationship and a focus on establishing familiarity and trust can reduce reporting bias. For the use of ACASI, considerations must be given to the context and characteristics of the study population.publishedVersio

Prescribing Patterns and Medicine Use at the University Teaching Hospital, Lusaka, Zambia

Background: There is paucity of data on rational drug use studies at tertiary hospitals in Zambia. The aim of this study was to assess the extent of rational drug use at the adults and paediatrics outpatient departments of the University Teaching Hospital (UTH) using World Health Organization (WHO) standardized drug-use indicators.Methods: Cross-sectional, descriptive, retrospective study of prescription encounters, selected using systematic random sampling methods was conducted at the adult and paediatric outpatient departments of UTH. WHO format of core and complimentary drug use indicators were used to collect prescribing indicators, patient care data which included consultation time, dispensing time and knowledge of correct dosage.Results: A total of 1486 drugs encounters were prescribed from both adult and paediatric outpatient wings in 2015. The average number of drugs per prescription was 2.5(SD±1.58), with a range of 1 to 7 drugs per prescription. The antibiotic and injection-prescribing rate was 53.7% and 11.8%respectively. Generic prescribing was at 56.1%. Percentage of drugs prescribed from the Zambia Essential Medicines List (ZEML) was 98.1%. Average consulting and dispensing time was 9.5 minutes and 1.3 minutes respectively. Percentage of patients with knowledge of correct dosing schedule was 78.9%. Labelling of medicines was adequate. All consultation rooms did not have Standard Treatment Guidelines (STG's) or any reference literature and were not connected to the internet.Conclusion: Low rate of injection prescribing was rational but consultation times were shorter than recommended and therefore irrational. High rate of antibiotic prescribing was irrational going by WHO standards for health facilities and this could lead to microbial resistance. Brand name prescribing was also irrational and common. Prescribing outside the ZEML was minimal and rational

Table1_Impact of cash transfer programs on healthcare utilization and catastrophic health expenditures in rural Zambia: a cluster randomized controlled trial.docx

BackgroundNearly 100 million people are pushed into poverty every year due to catastrophic health expenditures (CHE). We evaluated the impact of cash support programs on healthcare utilization and CHE among households participating in a cluster-randomized controlled trial focusing on adolescent childbearing in rural Zambia.Methods and findingsThe trial recruited adolescent girls from 157 rural schools in 12 districts enrolled in grade 7 in 2016 and consisted of control, economic support, and economic support plus community dialogue arms. Economic support included 3 USD/month for the girls, 35 USD/year for their guardians, and up to 150 USD/year for school fees. Interviews were conducted with 3,870 guardians representing 4,110 girls, 1.5–2 years after the intervention period started. Utilization was defined as visits to formal health facilities, and CHE was health payments exceeding 10% of total household expenditures. The degree of inequality was measured using the Concentration Index. In the control arm, 26.1% of the households utilized inpatient care in the previous year compared to 26.7% in the economic arm (RR = 1.0; 95% CI: 0.9–1.2, p = 0.815) and 27.7% in the combined arm (RR = 1.1; 95% CI: 0.9–1.3, p = 0.586). Utilization of outpatient care in the previous 4 weeks was 40.7% in the control arm, 41.3% in the economic support (RR = 1.0; 95% CI: 0.8–1.3, p = 0.805), and 42.9% in the combined arm (RR = 1.1; 95% CI: 0.8–1.3, p = 0.378). About 10.4% of the households in the control arm experienced CHE compared to 11.6% in the economic (RR = 1.1; 95% CI: 0.8–1.5, p = 0.468) and 12.1% in the combined arm (RR = 1.1; 95% CI: 0.8–1.5, p = 0.468). Utilization of outpatient care and the risk of CHE was relatively higher among the least poor than the poorest households, however, the degree of inequality was relatively smaller in the intervention arms than in the control arm.ConclusionsEconomic support alone and in combination with community dialogue aiming to reduce early childbearing did not appear to have a substantial impact on healthcare utilization and CHE in rural Zambia. However, although cash transfer did not significantly improve healthcare utilization, it reduced the degree of inequality in outpatient healthcare utilization and CHE across wealth groups.Trial Registrationhttps://classic.clinicaltrials.gov/ct2/show/NCT02709967, ClinicalTrials.gov, identifier (NCT02709967).</p

Hospital prescribing patterns of antibiotics in Zambia using the WHO prescribing indicators post-COVID-19 pandemic : findings and implications

Background: Antimicrobial resistance (AMR) is a global public health problem that is fuelled by the inappropriate prescribing of antibiotics especially those from the 'Watch' and 'Reserve' antibiotic list. The irrational prescribing of antibiotics is particularly prevalent in developing countries, including Zambia. Consequently, there is a need to better understand prescribing patterns across sectors in Zambia as a basis for future interventions. This study evaluated the prescribing patterns of antibiotics using the WHO prescribing indicators alongside the Access, Watch, and Reserve (AWaRe) classification system post-COVID pandemic at a Faith-based Hospital in Zambia. Methods: A cross-sectional study was conducted from August 2023 to October 2023 involving the review of medical records at St. Francis Mission Hospital in Zambia. A WHO-validated tool was used to evaluate antibiotic prescribing patterns alongside the AWaRe classification tool. Results: Out of 800 medical records reviewed, 2003 medicines were prescribed. Each patient received an average of 2.5 medicines per prescription. Antibiotics were prescribed in 72.3% of encounters, of which 28.4% were injectable. The most frequently prescribed antibiotics were amoxicillin (23.4% - Access), metronidazole (17.1% - Access), ciprofloxacin (8% - Watch), and ceftriaxone (7.4% - watch), with 77.1% overall from the 'Access' list. Encouragingly, 96.5% of the medicines were prescribed by their generic names and 98% were from the Zambia Essential Medicines List. Conclusions: There were high rates of antibiotic prescribing including injectable antibiotics, which needs addressing going forward. It is crucial to implement targeted measures, including antimicrobial stewardship programs, to improve future antibiotic prescribing in Zambia and reduce the risk of AMR
