Evaluating implementation of "management of Possible Serious Bacterial Infection (PSBI) when referral is not feasible" in primary health care facilities in Sindh province, Pakistan

Improving possible serious bacterial infection (PSBI) management in young infants when referral is not feasible: lessons from embedded implementation research in Ethiopia and Kenya

BACKGROUND

Sepsis is a leading cause of neonatal mortality, despite the availability of effective treatment of possible serious bacterial illness (PSBI), including when referral to a hospital is not feasible. Gaps in access and delivery worsened during COVID-19. We conducted embedded implementation research in Ethiopia and Kenya aimed at mitigating the impact of COVID-19 and addressing various implementation challenges to improve PSBI management.

METHODS

The implementation research projects were implemented at the subnational level in Ethiopia and Kenya between November 2020-June 2022 (Ethiopia) and December 2020-August 2022 (Kenya). Guided by the implementation research frameworks, both projects conducted mixed formative quantitative and exploratory research from April to May 2021, followed by summative evaluations conducted between June and July 2022. Frameworks encompassed Consolidated Framework for Implementation Research (CFIR), Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM), as well as health systems framework that incorporates cascades of care and World Health Organization Health Systems Building Blocks. Results were synthesized across the projects through document review and sharing cross-project measures and strategies through a project community of practice.

RESULTS

Despite differences in settings across the projects, cross-cutting facilitators included community health worker program and support, and existence of guidelines for PSBI management at primary care levels. Barriers included community attitudes towards seeking care for sick newborns, COVID-19 risks and fear, and lack of health care worker competence. Country-specific contextual barriers included supply chain issues, civil conflict (Ethiopia), and labor strikes (Kenya). Strategies chosen to mitigate barriers and support implementation and sustainability in both settings included leveraging community health workers to address resistance to care-seeking, health workers' training, COVID-19 infection prevention measures, stakeholder engagement, and advocacy to integrate PSBI management into existing programs, policies, and training. Other strategies addressing emerging project-specific barriers, included improving follow-up through a community health desk and PSBI mobile app (Kenya) and supply chain strengthening (Ethiopia). Both projects improved PSBI management coverage, increased adoption and uptake, and informed national policy changes supporting potential for sustainability.

CONCLUSIONS

Pragmatic embedded implementation research effectively supports the identification of barriers and mapping to strategies designed to increase effective coverage of PSBI management when referral is not feasible during the COVID-19 pandemic. Despite differences in context, cross-cutting strategies identified could inform broader scale-up in the region, including during future health system shocks.

Measuring implementation outcomes in the context of scaling up possible serious bacterial infection guidelines: Implications for measurement and programs

BACKGROUND

Reducing the burden of neonatal sepsis requires timely identification and initiation of suitable antibiotic treatment in primary health care (PHC) settings. Countries are encouraged to adopt simplified antibiotic regimens at the PHC level for treating sick young infants (SYI) with signs of possible serious bacterial infection (PSBI). As countries implement PSBI guidelines, more lessons on effective implementation strategies and outcome measurements are needed. We document pragmatic approaches used to design, measure and report implementation strategies and outcomes while adopting PSBI guidelines in Kenya.

METHODS

We designed implementation research using longitudinal mixed methods embedded in a continuous regular systematic learning and adoption of evidence in the PHC context. We synthesized formative data to co-create with stakeholders, implementation strategies to incorporate PSBI guidelines into routine service delivery for SYIs. This was followed by quarterly monitoring for learning and feedback on the effect of implementation strategies, documented lessons learned and tracked implementation outcomes. We collected endline data to measure the overall effect on service level outcomes.

RESULTS

Our findings show that characterizing implementation strategies and linking them with implementation outcomes, helps illustrate the pathway between the implementation process and outcomes. Although we have demonstrated that it is feasible to implement PSBI in PHC, effective investment in continuous capacity strengthening of providers through blended approaches, efficient use of available human resources, and improving the efficiency of service areas for managing SYIs optimizes timely identification and management of SYI. Sustained provision of commodities for management of SYI facilitates increased uptake of services. Strengthening facility-community linkages supports adherence to scheduled visits. Enhancing the caregiver's preparedness during postnatal contacts in the community or facility will facilitate the effective completion of treatment.

CONCLUSION

Careful design, and definition of terms related to the measurement of implementation outcomes and strategies enable ease of interpretation of findings. Using the taxonomy of implementation outcomes help frame the measurement process and provides empirical evidence in a structured way to demonstrate causal relationships between implementation strategies and outcomes. Using this approach, we have illustrated that the implementation of simplified antibiotic regimens for treating SYIs with PSBI in PHC settings is feasible in Kenya.

Implementation research to increase treatment coverage of possible serious bacterial infections in young infants when a referral is not feasible: lessons learnt

BACKGROUND

The objective was to achieve high coverage of possible serious bacterial infections (PSBI) treatment using the World Health Organization (WHO) guideline for managing it on an outpatient basis when referral to a hospital is not feasible.

METHODS

We implemented this guideline in the programme settings at 10 Basic Health Units (BHU) in two rural districts of Sindh in Pakistan using implementation research. A Technical Support Unit supported the programme to operationalize guidelines, built capacity of health workers through training, monitored their clinical skills, mentored them and assured quality. The community-based health workers visited households to identify sick infants and referred them to the nearest BHU for further management. The research team collected data.

RESULTS

Of 17 600 identified livebirths, 1860 young infants with any sign of PSBI sought care at BHUs and 1113 (59.8%) were brought by families. We achieved treatment coverage of 95%, assuming an estimated 10% incidence of PSBI in the first 2 months of life and that 10% of young infants came from outside the study catchment area. All 923 infants (49%; 923/1860) 7-59 days old with only fast breathing (pneumonia) treated with outpatient oral amoxicillin were cured. Hospital referral was refused by 83.4% (781/937) families who accepted outpatient treatment; 92.2% (720/781) were cured and 0.8% (6/781) died. Twelve (7.6%; 12/156) died among those treated in a hospital.

CONCLUSION

It is feasible to achieve high coverage by implementing WHO PSBI management guidelines in a programmatic setting when a referral is not feasible.

Implementation of distance learning IMCI training in rural districts of Tanzania

BACKGROUND

The standard face-to-face training for the integrated management of childhood illness (IMCI) continues to be plagued by concerns of low coverage of trainees, the prolonged absence of trainees from the health facility to attend training and the high cost of training. Consequently, the distance learning IMCI training model is increasingly being promoted to address some of these challenges in resource-limited settings. This paper examines participants' accounts of the paper-based IMCI distance learning training programme in three district councils in Mbeya region, Tanzania.

METHODS

A cross-sectional qualitative descriptive design was employed as part of an endline evaluation study of the management of possible serious bacterial infection in Busokelo, Kyela and Mbarali district councils of Mbeya Region in Tanzania. Key informant interviews were conducted with purposefully selected policymakers, partners, programme managers and healthcare workers, including beneficiaries and training facilitators.

RESULTS

About 60 key informant interviews were conducted, of which 53% of participants were healthcare workers, including nurses, clinicians and pharmacists, and 22% were healthcare administrators, including district medical officers, reproductive and child health coordinators and programme officers. The findings indicate that the distance learning IMCI training model (DIMCI) was designed to address concerns about the standard IMCI model by enhancing efficiency, increasing outputs and reducing training costs. DIMCI included a mix of brief face-to-face orientation sessions, several weeks of self-directed learning, group discussions and brief face-to-face review sessions with facilitators. The DIMCI course covered topics related to management of sick newborns, referral decisions and reporting with nurses and clinicians as the main beneficiaries of the training. The problems with DIMCI included technological challenges related to limited access to proper learning technology (e.g., computers) and unfriendly learning materials. Personal challenges included work-study-family demands, and design and coordination challenges, including low financial incentives, which contributed to participants defaulting, and limited mentorship and follow-up due to limited funding and transport.

CONCLUSION

DIMCI was implemented successfully in rural Tanzania. It facilitated the training of many healthcare workers at low cost and resulted in improved knowledge, competence and confidence among healthcare workers in managing sick newborns. However, technological, personal, and design and coordination challenges continue to face learners in rural areas; these will need to be addressed to maximize the success of DIMCI.

Barriers to optimal care and strategies to promote safe and optimal management of sick young infants during the COVID-19 pandemic: A multi-country formative research study

Background

Essential health and nutrition services for pregnant women, newborns, and children, particularly in low- and middle-income countries (LMICs), are disrupted by the COVID-19 pandemic. This formative research was conducted at five LMICs to understand the pandemic's impact on barriers to and mitigation for strategies of care-seeking and managing possible serious bacterial infection (PSBI) in young infants.

Methods

We used a convergent parallel mixed-method design to explore the possible factors influencing PSBI management, barriers, and facilitators at three levels: 1) national and local policy, 2) the health systems, public and private facilities, and 3) community and caregivers. We ascertained trends in service provision and utilisation across pre-lockdown, lockdown, and post-lockdown periods by examining facility records and community health worker registers.

Results

The pandemic aggravated pre-existing challenges in the identification of young infants with PSBI; care-seeking, referral, and treatment due to several factors at the policy level (limited staff and resource reallocation), health facility level (staff quarantine, sub-optimal treatment in facilities, limited duration of service availability, lack of clear guidelines on the management of sick young infants, and inadequate supplies of protective kits and essential medicines) and at the community level (travel restrictions, lack of transportation, and fear of contracting the infection in hospitals). Care-seeking shifted to faith healers, traditional and informal private sources, or home remedies. However, caregivers were willing to admit their sick young infants to the hospital if advised by doctors. A review of facility records showed low attendance (<50%) of sick young infants in the OPD/emergencies during lockdowns in Bangladesh, India (both sites) and Pakistan, but it gradually increased as lockdowns eased. Stakeholders suggested aspirational and pragmatic mitigation strategies.

Conclusions

We obtained useful insights on health system preparedness during catastrophes and strategies to strengthen services and improve utilisation regarding PSBI management. The current pandemic provides an opportunity for implementing various mitigation strategies at the policy, health system, and community levels to improve preparedness.

Home-based management of neonatal sepsis: 23 years of sustained implementation and effectiveness in rural Gadchiroli, India, 1996-2019

Introduction

Although hospitalisation remains the preferred management for neonatal sepsis, it is often not possible in resource-limited settings. The Home-Based Newborn Care (HBNC) study in Gadchiroli, India (1995–1998) was the first trial to demonstrate that neonatal sepsis can be managed in the community. HBNC continues to operate in Gadchiroli. In 2015, WHO recommended community-based management of neonatal sepsis when hospitalisation is not feasible but called for implementation research. We studied the implementation and effectiveness of home-based management of neonatal sepsis over 23 years in Gadchiroli.

Methods

In this cohort study (1996–2019), community health workers (CHWs) visited neonates at home in 39 villages in Gadchiroli, India. CHWs screened, diagnosed sepsis and offered home-based antibiotic treatment if hospitalisation was refused. We evaluated the implementation outcomes of coverage, diagnostic fidelity and adoption. We assessed the association between treatment type and odds of neonatal death using mixed effects logistic regression. Time trends were analysed using the Mann-Kendall test.

Results

CHWs screened 93.8% (17 700/18 874) of neonates (coverage) and correctly diagnosed 89% (1051/1177) of sepsis episodes (diagnostic fidelity). Home-based management was preferred by 88.4% (929/1051) of parents (adoption), with 5.6 percent of total neonates receiving antibioties at home. Compared with neonates treated at home, the adjusted odds of death was 5.27 (95% CI 1.91 to 14.58) times higher when parents refused all treatment, 2.17 (95% CI 1.07 to 4.41) times higher when CHWs missed the diagnosis and 5.45 (95% CI 2.74 to 10.87) times higher when parents accepted hospital referral. Implementation outcomes remained consistent over 23 years (coverage p=0.57; fidelity p=0.57; adoption p=0.26; mortality p=0.71). The rate of facility births increased (p<0.01) and the sepsis incidence decreased (p<0.05) over 23 years.

Conclusion

Implementation of home-based management of neonatal sepsis was sustainable and effective over 23 years. During this period, the need for home-based management in Gadchiroli is declining. Home-based management is advised where sepsis remains a major cause of neonatal mortality and hospital access is limited.

A multi-country implementation research initiative to jump-start scale-up of outpatient management of possible serious bacterial infections (PSBI) when a referral is not feasible: Summary findings and implications for programs

INTRODUCTION

Research on simplified antibiotic regimens for outpatient treatment of 'Possible Serious Bacterial Infection' (PSBI) and the subsequent World Health Organization (WHO) guidelines provide an opportunity to increase treatment coverage. This multi-country implementation research initiative aimed to learn how to implement the WHO guideline in diverse contexts. These experiences have been individually published; this overview paper provides a summary of results and lessons learned across sites.

METHODS SUMMARY

A common mixed qualitative and quantitative methods protocol for implementation research was used in eleven sites in the Democratic Republic of Congo (Equateur province), Ethiopia (Tigray and Oromia regions), India (Haryana, Himachal Pradesh, Maharashtra, and Uttar Pradesh states), Malawi (Central Region), Nigeria (Kaduna and Oyo states), and Pakistan (Sindh province). Key steps in implementation research were: i) policy dialogue with the national government and key stakeholders, ii) the establishment of a 'Technical Support Unit' with the research team and district level managers, and iii) development of an implementation strategy and its refinement using an iterative process of implementation, programme learning and evaluation.

RESULTS SUMMARY

All sites successfully developed and evaluated an implementation strategy to increase coverage of PSBI treatment. During the study period, a total of 6677 young infants from the study catchment area were identified and treated at health facilities in the study area as inpatients or outpatients among 88179 live births identified. The estimated coverage of PSBI treatment was 75.7% (95% CI 74.8% to 78.6%), assuming a 10% incidence of PSBI among all live births. The treatment coverage was variable, ranging from 53.3% in Lucknow, India to 97.3% in Ibadan, Nigeria. The coverage of inpatient treatment ranged from 1.9% in Zaria, Nigeria, to 33.9% in Tigray, Ethiopia. The outpatient treatment coverage ranged from 30.6% in Pune, India, to 93.6% in Zaria, Nigeria. Overall, the case fatality rate (CFR) was 14.6% (95% CI 11.5% to 18.2%) for 0-59-day old infants with critical illness, 1.9% (95% CI 1.5% to 2.4%) for 0-59-day old infants with clinical severe infection and 0.1% for fast breathing in 7-59 days old. Among infants treated as outpatients, CFR was 13.7% (95% CI 8.7% to 20.2%) for 0-59-day old infants with critical illness, 0.9% (95% CI 0.6% to 1.2%) for 0-59-day old infants with clinical severe infection, and 0.1% for infants 7-59 days old with fast breathing.

CONCLUSION

Important lessons on how to conduct each step of implementation research, and the challenges and facilitators for implementation of PSBI management guideline in routine health systems are summarised and discussed. These lessons will be used to introduce and scale-up implementation in relevant Low- and middle-income countries.

Performance of Automated Point-of-Care Respiratory Rate Counting versus Manual Counting in Children under Five Admitted with Severe Febrile Illness to Kisantu Hospital, DR Congo

To improve the early recognition of danger signs in children with severe febrile illness in low resource settings, WHO promotes automated respiratory rate (RR) counting, but its performance is unknown in this population. Therefore, we prospectively evaluated the field performance of automated point-of-care plethysmography-based RR counting in hospitalized children with severe febrile illness (<5 years) in DR Congo. A trained research nurse simultaneously counted the RR manually (comparative method) and automatically with the Masimo Rad G pulse oximeter. Valid paired RR measurements were obtained in 202 (83.1%) children, among whom 43.1% (87/202) had fast breathing according to WHO criteria based on manual counting. Automated counting frequently underestimated the RR (median difference of -1 breath/minute; p2.5-p97.5 limits of agreement: -34-6), particularly at higher RR. This resulted in a failure to detect fast breathing in 24.1% (21/87) of fast breathing children (positive percent agreement: 75.9%), which was not explained by clinical characteristics (p > 0.05). Children without fast breathing were mostly correctly classified (negative percent agreement: 98.3%). In conclusion, in the present setting the automated RR counter performed insufficiently to facilitate the early recognition of danger signs in children with severe febrile illness, given wide limits of agreement and a too low positive percent agreement.

Management of possible serious bacterial infection in young infants closer to home when referral is not feasible: Lessons from implementation research in Himachal Pradesh, India

Background

Government of India and the World Health Organization have guidelines for outpatient management of young infants 0–59 days with signs of Possible Serious Bacterial Infection (PSBI), when referral is not feasible. Implementation research was conducted to identify facilitators and barriers to operationalizing these guidelines.

Methods

Himachal Pradesh government implemented the guidelines in program settings supported by Centre for Health Research and Development, Society for Applied Studies. The strategy included community sensitization, skill enhancement of Accredited Social Health Activists (ASHA), Auxiliary Nurse Midwives (ANMs) and Medical Officers (MOs) to identify PSBI and treat when referral was not feasible. The research team collected information on facilitators and barriers. A technical support unit provided training and oversight.

Findings

Among 1997 live births from June 2017 to January 2019, we identified 160 cases of PSBI in young infants resulting in a coverage of 80%, assuming an incidence of 10%. Of these,29(18.1%) had signs of critical illness (CI), 92 (57.5%) had clinical severe infection (CSI), 5 (3.1%)had severe pneumonia (only fast breathing in young infants 0–6 days), while 34 (21%) had pneumonia (only fast breathing in young infants 7–59 days). Hospital referral was accepted by 48/160 (30%), whereas 112/160 (70%) were treated with the simplified treatment regimens at primary level facilities. Of the 29 infants with CI, 18 (62%) accepted referral; 26 (90%) recovered while 3 (10%) who had accepted referral, died. Of the 92 infants who had CSI, 86 (93%) recovered, 65 (71%) received simplified treatment and one infant who had accepted referral, died. All the five infants who had severe pneumonia, recovered; 3 (60%) had received simplified treatment. Of the 34 pneumonia cases, 33 received simplified treatment of which 5 (15%) failed treatment; two out of these 5 died. Overall, 6/160 infants died (case-fatality-rate 3.4%); 2 in the simplified treatment (case-fatality-rate 1.8%) and 4 in the hospital group (case-fatality-rate 8.3%). Delayed identification and care-seeking by families and health system weaknesses like manpower gaps and interrupted supplies were challenges in implementation.

Conclusions

Implementation of the guidelines in program settings is possible and acceptable. Scaling up would require creating community awareness, early identification and appropriate care-seeking, strengthening ASHA home-visitation program, building skills and confidence of MOs and ANMs, uninterrupted supplies and a dependable referral system.
