Implementation science in low-resource settings: using the interactive systems framework to improve hand hygiene in a tertiary hospital in Ghana

The integration of quality improvement and implementation science methods and frameworks in healthcare: a systematic review

OBJECTIVES

Quality Improvement (QI) and Implementation Science (IS) are both frequently utilised in health research. Little is known about how they are integrated within studies, and whether combined they add value. This systematic review sought to investigate how QI and IS theories and strategies are integrated within healthcare-based studies.

METHODS

A systematic search was conducted across five databases. Duplicates, studies published prior to 2014, systematic and scoping reviews, and study protocols were removed. The retrieved title abstracts were screened, and the full texts of eligible studies were reviewed in pairs using Covidence software. Of the included studies, data were extracted using a predefined template, and studies were critically appraised using the QI Minimum Quality Criteria Set. Frequency analysis of the use of QI or IS tools was conducted, as well as a narrative analysis of the integration of QI and IS in each study.

RESULTS

The database search returned 3,407 title abstracts, of which 1,618 were screened. Assessment for eligibility resulted in the identification of 149 studies, of which the full texts were reviewed, and 12 studies included in the final analysis. These 12 studies integrated QI and IS methods to implement an intervention in tertiary healthcare. The Plan-Do-Study-Act (PDSA) cycle was the most frequently used QI tool and the Theoretical Domains Framework, Behaviour Change Wheel (including Capabilities, Opportunity and Motivation) and the Consolidated Framework for Implementation Research were the most frequently used IS frameworks.

CONCLUSION

The study highlights a lack of consistent terminology across the QI and IS fields, as well as opportunities for greater integration of the two fields to enhance study design, implementation and sustainability, and to improve healthcare performance.

Enhancing infection prevention and control through hand hygiene compliance in six Ugandan hospitals using quality improvement approaches

Introduction

Hand hygiene (HH) plays a crucial role in mitigating healthcare-associated infections. Improving HH compliance in healthcare facilities in resource-limited settings is urgently needed.

Methods

We implemented the World Health Organization (WHO) HH improvement strategy using a continuous quality improvement (CQI) approach targeting improvement in HH compliance by healthcare workers (HCWs). An intervention was implemented in six hospitals using a longitudinal study design between May 2019 and April 2023. We set up and monitored infection prevention and control (IPC) and HH programs using WHO's infection prevention and control assessment framework at the facility level (IPCAF) and hand hygiene self-assessment framework (HHSAF) tools. We implemented HH interventions using CQI techniques while targeting HCW HH knowledge and compliance with the WHO's Five Moments of HH.

Results and discussion

By the end of the intervention, IPC and HH capacity improved in all six hospitals, from a median score of 547.0 and 252.5 on IPCAF and HHSAF tools at baseline to an advanced score of 635.0 and 350.0 at endline assessment, respectively. Similarly, HCWs' HH knowledge improved in all hospitals, from a mean score of 45.0% at baseline to 76.0% at endline assessment, most notably among nurses. HH compliance, as assessed using WHO's HH observation tool, at least doubled in all hospitals, rising from 19.9% to 53.8%, with before touching a patient registering the highest (22-fold) improvement. On linear regression analysis, no significant association was observed between HH compliance and IPCAF b = -0.0004 (95% CI -0.093, 0.93) p = 0.990, HHSAF b = 0.009 (95% CI -.0127, 0.145) p = 0.842 and HCW knowledge on HH/IPC b = -0.165 (95% CI 0.815, 0.485) p = 0.519. This is the first documented comprehensive utilization of CQI approaches to implement HH as an entry point for the development of hospital IPC programs, and evaluation of WHO tools and approaches for IPC and HH improvement in Uganda.

Conclusion

Implementation of the WHO HH improvement strategy using a CQI approach can lead to remarkable improvement in HH capacity, and HCW compliance and knowledge in hospitals within resource-limited settings.

International evidence-based guidelines on hypertension and type 2 diabetes mellitus: A systematic review

This systematic review provides a high-quality, comprehensive summary of recommendations on hypertension (HT) and type 2 diabetes mellitus (T2DM), accentuating patient blood pressure, HbA1c levels, patterns of drug treatment, management, and screening of these diseases. The overall objective of the review is to support adapting existing clinical practice guidelines in Indonesia, Vietnam, and Myanmar. The database PubMed and the web search engines Google and Google Scholar were searched from October to December 2019 for evidence-based guidelines covering the overall disease management in Europe, the United States of America, and low and middle-income countries (Indonesia, Vietnam, and Myanmar-IVM later on). Nine studies were selected for the review, seven concerning HT and five T2DM. Guidelines in IVM and Europe identified HT as increased blood pressure (BP; ≥140/90 mmHg). IVM guidelines also recommended commencing drug treatment if lifestyle interventions were not successful. Four international HT guidelines recommended monitoring BP every few months, and the other three guidelines gave recommendations based on the patient's current BP levels. All five T2DM guidelines recommended target HbA1c levels below 7%-6.5%, but only IVM guidelines included re-examination every 3-6 months. Metformin was recommended as the first choice of medical treatment, if not contraindicated. Amid the guidelines' recommendations, there were no major variations in the Class of recommendation and Level of evidence (except IVM guidelines where COR and LOE were missing). Revision and completion of IVM guidelines by this grading system would enhance evidence-based and informed decisions in clinical care.

SafeHANDS: A Multimodal Hand Hygiene Intervention in a Resource-Limited Neonatal Unit

BACKGROUND

Hand hygiene (HH) is a cornerstone of programmes to prevent healthcare associated infections (HAI) globally, but HH interventions are seldom reported from African neonatal units.

METHODS

We conducted a quasi-experimental study evaluating the impact of a multi-modal intervention (SafeHANDS) on HH compliance rates, alcohol-based handrub (ABHR) usage, the Hand Hygiene Self-Assessment Framework (HHSAF) score, and healthcare-associated bloodstream infection (HA-BSI) rates at a 132-bed South African neonatal unit (4 wards and 1 neonatal intensive care unit [NICU]). The intervention included a campaign logo, HH training, maternal education leaflets, ABHR bottles for staff, and the setting of HH performance targets with feedback. Three 5-month study phases were completed in July 2020 (baseline), December 2020 (early) and May 2021 (intensive).

RESULTS

A total of 2430 HH opportunities were observed: 1002 (41.3%) at baseline, 630 (25.9%) at early and 798 (32.8%) at intensive study phases. At baseline, the overall neonatal unit HH compliance rate was 61.6%, ABHR use was 70 mL/patient day, and the baseline HHSAF score was 'basic' (165). The overall neonatal unit HH compliance rate was unchanged from baseline to intensive phases (617/1002 [61.6%] vs. 497/798 [62.3%]; p = 0.797). The ABHR use remained similar between phases (70 versus 73 mL/patient day). The HHSAF score improved to 'intermediate' level (262). There was no change in the neonatal unit HA-BSI rate.

CONCLUSION

Despite improvement in the HHSAF score, no improvement in overall HH compliance rates, ABHR usage, or HA-BSI rates was observed. Future HH interventions in resource-limited neonatal units should incorporate implementation science and behaviour modification strategies to better understand the barriers and facilitators of HH best practice.

Improve-mentation for Faster Testing and Spread of Health Service Delivery Innovations

Can we speed the testing, implementation and spread of management innovations in a systematic way to also contribute to scientific knowledge? Researchers and implementers have developed an approach to test and revise a local version of an innovation during its implementation. The chapter starts with a case example of an application of this combination of implementation and quality improvement sciences and practices (improve-mentation). It then summarizes four examples of this approach so as to help understand what improve-mentation is and how it is different from traditional quality improvement and traditional implementation of evidence-based practices. It considers gaps in knowledge that are hindering both more use of improve-mentation to generate scientific knowledge about spread and implementation, as well as more use of improve-mentation by health care service organizations and researchers. It closes by proposing fruitful research and development that can address these knowledge gaps to speed the implementation, sustainment and spread of care and management innovations.

Improving hand hygiene practices in two regional hospitals in Kenya using a continuous quality improvement (CQI) approach

Background

Hand hygiene (HH) is central in prevention of health care-associated infections. In low resource settings, models to improve HH compliance are needed. We implemented a continuous quality improvement (CQI) program targeting HH in two hospitals in Kenya.

Objective

To determine the impact of the HH CQI program and identify factors associated with HH compliance between 2018 and 2019.

Methods

A CQI project targeting the improvement of hand hygiene was implemented, including training and mentorship. Data were collected monthly between April 2018 and December 2019 in Thika and Kitale Hospitals. Healthcare workers trained on Infection Prevention and Control (IPC) observed and recorded HH opportunities and subsequent compliance among staff, including nurses, clinicians, and auxiliary staff, using the World Health Organization’s “My Five Moments for Hand Hygiene” tool. Covariates were explored using mixed-effects logistic regression with random department-level intercepts.

Results

Hand hygiene compliance improved from 27% at baseline to 44% after 21 months. Indication/moment for HH was significantly associated with compliance. Adjusting for site, professional category and department, compliance was higher after a moment of body fluid exposure (aOR 1.43, 95% CI 1.17–1.74, p value < 0.001) and lower before an aseptic procedure (aOR 0.12, 95% CI 0.08–0.17, p value < 0.001) compared to after patient contact. Wearing of gloves often replaced proper HH in surgical departments, which although not significant, had lower compliance compared to departments for internal medicine (aOR 0.93, 95% CI 0.85–1.02). Adjusted HH compliance from all quarters improved from baseline, but comparing each quarter to the previous quarter, the improvement fluctuated over time.

Conclusion

Training and mentorship on the importance of HH for all moments is needed to improve overall HH compliance. CQI with regular monitoring and feedback of HH performance can be an effective approach in improving HH compliance in public hospitals in Kenya.

Quality Improvement Initiative to Improve Hand Hygiene Compliance in Indian Special Newborn Care Unit

Supplemental Digital Content is available in the text.

Pilot data on Hand hygiene (HH) compliance using a standard World Health Organisation checklist for 1-week suggested only 20% compliance. So, we planned a Quality Improvement study to improve HH compliance among health care providers in our Special Newborn Care Unit from 20% to 60% over 12 months.

The Impact of Quality Improvement Interventions in Improving Surgical Infections and Mortality in Low and Middle-Income Countries: A Systematic Review and Meta-Analysis

BACKGROUND

Morbidity and mortality in surgical systems in low- and middle-income countries (LMICs) remain high compared to high-income countries. Quality improvement processes, interventions, and structure are essential in the effort to improve peri-operative outcomes.

METHODS

A systematic review and meta-analysis of interventional studies assessing quality improvement processes, interventions, and structure in developing country surgical systems was conducted according to the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were included if they were conducted in an LMIC, occurred in a surgical setting, and measured the effect of an implementation and its impact. The primary outcome was mortality, and secondary outcomes were rates of rates of hospital-acquired infection (HAI) and surgical site infections (SSI). Prospero Registration: CRD42020171542.

RESULT

Of 38,273 search results, 31 studies were included in a qualitative synthesis, and 28 articles were included in a meta-analysis. Implementation of multimodal bundled interventions reduced the incidence of HAI by a relative risk (RR) of 0.39 (95%CI 0.26 to 0.59), the effect of hand hygiene interventions on HAIs showed a non-significant effect of RR of 0.69 (0.46-1.05). The WHO Safe Surgery Checklist reduced mortality by RR 0.68 (0.49 to 0.95) and SSI by RR 0.50 (0.33 to 0.63) and antimicrobial stewardship interventions reduced SSI by RR 0.67 (0.48-0.93).

CONCLUSION

There is evidence that a number of quality improvement processes, interventions and structural changes can improve mortality, HAI and SSI outcomes in the peri-operative setting in LMICs.

The Applications of Implementation Science in Water, Sanitation, and Hygiene (WASH) Research and Practice

BACKGROUND

Delivery of high quality, at-scale, and sustained services is a major challenge in the water, sanitation, and hygiene (WASH) sector, made more challenging by a dearth of evidence-based models for adaption across contexts in low- and middle-income countries.

OBJECTIVE

We aim to describe the value of implementation science (IS) for the WASH sector and provide recommendations for its application.

METHODS

We review concepts from the growing field of IS-defined as the "scientific study of methods to promote the systematic uptake of research findings and other evidence-based practices into routine practice, and hence, to improve the quality and effectiveness of health services"-and we translate their relevance to WASH research, learning, and delivery.

DISCUSSION

IS provides a suite of methods and theories to systematically develop, evaluate, and scale evidence-based interventions. Though IS thinking has been applied most notably in health services delivery in high-income countries, there have been applications in low-income settings in fields such as HIV/AIDS and nutrition. Expanding the application of IS to environmental health, specifically WASH interventions, would respond to the complexity of sustainable service delivery. WASH researchers may want to consider applying IS guidelines to their work, including adapting pragmatic research models, using established IS frameworks, and cocreating knowledge with local stakeholders. https://doi.org/10.1289/EHP7762.

Neonatal mortality in rural northern Ghana and the three delays model: are we focusing on the right delays?

OBJECTIVE

The Three Delays Model outlines, three common delays that lead to poor newborn outcomes: (i) recognising symptoms and deciding to seek care; (ii) getting to care and; (iii) receiving timely, high-quality care. We gathered data for all newborn deaths within four districts in Ghana to explore how well the Three Delays Model explains outcomes.

METHODS

In this cross-sectional, observational study, trained field workers conducted verbal and social autopsies with the closest surviving relative (typically mothers) of all neonatal deaths across four districts in northern Ghana from September 2015 until April 2017. Data were collected using Survey CTO and analysed using StataSE 15.0. Frequencies and descriptive statistics were calculated for key variables.

RESULTS

247 newborn deaths were identified. Nearly 77% (190) of newborns who died were born at a health facility, and 48.9% (93) of those who died before discharge. Of the 149 newborns who were discharged or born at home, 71.8% (107) sought care at a facility for illness, and 72.9% (N = 78) of those did so within the same day of illness recognition. Of the 83 respondents who arranged for transportation, 82% (68) did so within 1 h. Newborns received prompt care but insufficient interventions - 25% or fewer received IV fluids, oral medications, antibiotics or oxygen.

CONCLUSIONS

These data suggest that women are following recommendations for safe delivery and prompt care-seeking. In rural northern Ghana, behaviour change interventions focused on mothers and families may not be as pressing as interventions focused on the Third Delay - obtaining timely, high-quality care.

Barriers and Facilitators of Using Quality Improvement To Foster Locally Initiated Innovation in Palliative Care Services in India

BACKGROUND

Quality improvement (QI) methods represent a vehicle for fostering locally initiated innovation cycles. We partnered with palliative care services from seven diverse practice settings in India to foster locally initiated improvement projects.

OBJECTIVE

To evaluate the implementation experiences of locally initiated palliative care improvement projects at seven diverse sites and understand the barriers and facilitators of using QI to improve palliative care in India.

PARTICIPANTS

We use a quota sampling approach to capture the perspectives of 44 local stakeholders in each of the following three categories (organizational leaders, clinic leaders, and clinical team members) through a semi-structured interview guide informed by the consolidated framework for implementation research (CFIR). We use standard qualitative methods to identify facilitators and barriers to using QI methods in seven diverse palliative care contexts.

RESULTS

Across all sites, respondents emphasized the following factors important in the success of quality improvement initiative: leveraging clinic level data, QI methods training, provider buy-in, engaged mentors, committed leadership, team support, interdepartmental coordination, collaborations with other providers, local champions, and having a structure for accountability. Barriers to using QI methods to improve palliative care services included lack of designated staff, high patient volume, resources, patient population geographic constraints, general awareness and acceptance of palliative care, and culture.

CONCLUSIONS

Empowering local leaders and medical personnel to champion, design, and iterate using QI methods represents a promising powerful tool to spread palliative care services in developing countries.

Reflections on "Building Back Better" Child and Adolescent Mental Health Care in a Low-Resource Postemergency Setting: The Case of Sierra Leone

Over the past three decades, Sierra Leone has experienced two major humanitarian crises: an armed conflict (1991-2002) and an Ebola virus disease outbreak (2014-2015). In addition to these country-wide crises, the capital Freetown experienced a mudslide affecting thousands of people in 2017. In response to these emergencies, donors and aid organizations showed an increased interest in supporting and implementing mental health and psychosocial support interventions. Despite these efforts, the mental health infrastructure of the country remains frail. Specifically, systemic improvements in the implementation of evidence-based mental health care for children and adolescents appear to be lacking. In this article, the Interactive Systems Framework for Dissemination and Implementation is used as a tool to analyze issues related to the development of a sustainable, contextually relevant child and adolescent mental health-care delivery system. The author draws on her long-term experience as a child mental health specialist in Sierra Leone. Observations and hypotheses are tested and supplemented by formal and informal reports and national and international literature. The three systems described by the Interactive Systems Framework are explored in the context of Sierra Leone: (1) Synthesis and Translation, (2) Support, and (3) Delivery. Interaction between the three Systems is discussed as critical to the successful dissemination and implementation of interventions. Ample attention is given to contextual factors that are believed to be paramount to the development of child and adolescent mental health care in Sierra Leone. The article concludes with a reflection on the usefulness of the Interactive Systems Framework in the dissemination and implementation of child and adolescent mental health-care interventions in low-resource, postemergency settings. It is suggested that, in addition to funding and policies, the child and adolescent mental health system in Sierra Leone could benefit from the development of contextually relevant interventions, improvement of capacity-building efforts, and acknowledgment of the role of community-based practitioners in the delivery of services. Local mental health experts, especially those trained in child and adolescent mental health, should be empowered to work together with culturally competent expatriate professionals to improve child and adolescent mental health care in Sierra Leone.

Adapting Translational Research Methods to Water, Sanitation, and Hygiene

Translational research applies scientific techniques to achieve practical outcomes, connecting pure research and pure practice. Many translational research types have arisen since the mid-1900s, reflecting the need to better integrate scientific advancement with policy and practice. Water, sanitation, and hygiene (WaSH) development efforts have aimed to reduce morbidity and mortality and improve service delivery; thus, associated research has a strong orientation toward applied studies that use diverse methods to support decision-making. Drawing from knowledge that emerged to support other professional fields, such as manufacturing and clinical healthcare, we characterize different types of translational research and clarify nomenclature and principles. We describe study approaches relevant to translational research questions, and offer overarching recommendations, specific examples, and resources for further study as practical advice to professionals who seek to apply translational methods to WaSH problems. To enhance collective outcomes, professionals should mindfully align projects within the translational spectrum. We further recommend overarching good practices such as documenting intervention adaptations, overtly considering contextual factors, and better distinguishing efficacy from effectiveness research by replicating studies in different contexts. By consciously improving the compatibility and linkages between WaSH science and practice, this guide can accelerate urgently needed progress toward global development goals.

Inclusion of Real-Time Hand Hygiene Observation and Feedback in a Multimodal Hand Hygiene Improvement Strategy in Low-Resource Settings

Importance

Hand hygiene adherence monitoring and feedback can reduce health care-acquired infections in hospitals. Few low-cost hand hygiene adherence monitoring tools exist in low-resource settings.

Objective

To pilot an open-source application for mobile devices and an interactive analytical dashboard for the collection and visualization of health care workers' hand hygiene adherence data.

Design, Setting, and Participants

This prospective multicenter quality improvement study evaluated preintervention and postintervention adherence with the 5 Moments for Hand Hygiene, as suggested by the World Health Organization, among health care workers from April 23 to May 25, 2018. A novel data collection form, the Hand Hygiene Observation Tool, was developed in open-source software and used to measure adherence with hand hygiene guidelines among health care workers in the inpatient therapeutic feeding center and pediatric ward of Anka General Hospital, Anka, Nigeria, and the postoperative ward of Noma Children's Hospital, Sokoto, Nigeria. Qualitative data were analyzed throughout data collection and used for immediate feedback to staff. A more formal analysis of the data was conducted during October 2018.

Exposures

Multimodal hand hygiene improvement strategy with increased availability and accessibility of alcohol-based hand sanitizer, staff training and education, and evaluation and feedback in near real-time.

Main Outcomes and Measures

Hand hygiene adherence before and after the intervention in 3 hospital wards, stratified by health care worker role, ward, and moment of hand hygiene.

Results

A total of 686 preintervention adherence observations and 673 postintervention adherence observations were conducted. After the intervention, overall hand hygiene adherence increased from 32.4% to 57.4%. Adherence increased in both wards in Anka General Hospital (inpatient therapeutic feeding center, 24.3% [54 of 222 moments] to 63.7% [163 of 256 moments]; P < .001; pediatric ward, 50.9% [132 of 259 moments] to 68.8% [135 of 196 moments]; P < .001). Adherence among nurses in Anka General Hospital also increased in both wards (inpatient therapeutic feeding center, 17.7% [28 of 158 moments] to 71.2% [79 of 111 moments]; P < .001; pediatric ward, 45.9% [68 of 148 moments] to 68.4% [78 of 114 moments]; P < .001). In Noma Children's Hospital, the overall adherence increased from 17.6% (36 of 205 moments) to 39.8% (88 of 221 moments) (P < .001). Adherence among nurses in Noma Children's Hospital increased from 11.5% (14 of 122 moments) to 61.4% (78 of 126 moments) (P < .001). Adherence among Noma Children's Hospital physicians decreased from 34.2% (13 of 38 moments) to 8.6% (7 of 81 moments). Lowest overall adherence after the intervention occurred before patient contact (53.1% [85 of 160 moments]), before aseptic procedure (58.3% [21 of 36 moments]), and after touching a patient's surroundings (47.1% [124 of 263 moments]).

Conclusions and Relevance

This study suggests that tools for the collection and rapid visualization of hand hygiene adherence data are feasible in low-resource settings. The novel tool used in this study may contribute to comprehensive infection prevention and control strategies and strengthening of hand hygiene behavior among all health care workers in health care facilities in humanitarian and low-resource settings.
