Novel point-of-care cytokine biomarker lateral flow test for the screening for sexually transmitted infections and bacterial vaginosis: study protocol of a multicentre multidisciplinary prospective observational clinical study to evaluate the performance and feasibility of the Genital InFlammation Test (GIFT).

INTRODUCTION: A prototype lateral flow device detecting cytokine biomarkers interleukin (IL)-1α and IL-1ß has been developed as a point-of-care test-called the Genital InFlammation Test (GIFT)-for detecting genital inflammation associated with sexually transmitted infections (STIs) and/or bacterial vaginosis (BV) in women. In this paper, we describe the rationale and design for studies that will be conducted in South Africa, Zimbabwe and Madagascar to evaluate the performance of GIFT and how it could be integrated into routine care. METHODS AND ANALYSIS: We will conduct a prospective, multidisciplinary, multicentre, cross-sectional and observational clinical study comprising two distinct components: a biomedical ('diagnostic study') and a qualitative, modelling and economic ('an integration into care study') part. The diagnostic study aims to evaluate GIFT's performance in identifying asymptomatic women with discharge-causing STIs (Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV) and Mycoplasma genitalium (MG)) and BV. Study participants will be recruited from women attending research sites and family planning services. Several vaginal swabs will be collected for the evaluation of cytokine concentrations (ELISA), STIs (nucleic acid amplification tests), BV (Nugent score) and vaginal microbiome characteristics (16S rRNA gene sequencing). The first collected vaginal swab will be used for the GIFT assay which will be performed in parallel by a healthcare worker in the clinic near the participant, and by a technician in the laboratory. The integration into care study aims to explore how GIFT could be integrated into routine care. Four activities will be conducted: user experiences and/or perceptions of the GIFT device involving qualitative focus group discussions and in-depth interviews with key stakeholders; discrete choice experiments; development of a decision tree classification algorithm; and economic evaluation of defined management algorithms. ETHICS AND DISSEMINATION: Findings will be reported to participants, collaborators and local government for the three sites, presented at national and international conferences, and disseminated in peer-reviewed publications.The protocol and all study documents such as informed consent forms were reviewed and approved by the University of Cape Town Human Research Ethics Committee (HREC reference 366/2022), Medical Research Council of Zimbabwe (MRCZ/A/2966), Comité d'Ethique pour la Recherche Biomédicale de Madagascar (N° 143 MNSAP/SG/AMM/CERBM) and the London School of Hygiene and Tropical Medicine ethics committee (LSHTM reference 28046).Before the start, this study was submitted to the Clinicaltrials.gov public registry (NCT05723484). TRIAL REGISTRATION NUMBER: NCT05723484.

Lower Dose of 5 mL of 1% Lidocaine is More Suitable than the Conventional 10 mL for Caudal Block in Transrectal Prostate Biopsy: A Retrospective Cohort Study.

Objectives: In Japan, caudal block with 1% lidocaine is commonly used for transrectal prostate biopsy. Although 10 mL of 1% lidocaine is commonly used, the appropriate dosage of 1% lidocaine has not been studied. Our hospital routinely uses two different doses (5 or 10 mL) of 1% lidocaine for caudal block for transrectal prostate biopsy. Herein, we retrospectively evaluated the efficacy and safety of both doses of 1% lidocaine. Methods: This retrospective study included 869 patients who underwent transrectal prostate biopsy with caudal block at our hospital. The amount of 1% lidocaine was determined by the day of the week on which the biopsy was performed, and the patient voluntarily chose the day of the biopsy, unaware of the dose of 1% lidocaine used on that day. Pain, anal sphincter tonus, cancer diagnosis rate, and early complications were compared. Results: In total, 466 and 403 patients received 5 and 10 mL of 1% lidocaine for a caudal block, respectively. After propensity-score matching for patient characteristics, each group contained 395 patients. The pain score, anal sphincter tonus score, or prostate cancer diagnosis rate were not significantly different between the two groups. However, rectal bleeding was significantly more frequent and severe in the 10-mL than the 5-mL group (p=0.018 and p=0.0036, respectively). The incidence of other complications was not significantly different between the groups. Conclusions: Our results suggest that 5 mL of 1% lidocaine may be more suitable than 10 mL for caudal block during transrectal prostate biopsy.

Examining multiple funding flows to public healthcare providers in low- and middle-income countries - results from case studies in Burkina Faso, Kenya, Morocco, Nigeria, Tunisia and Vietnam.

Provider payment methods are traditionally examined by appraising the incentive signals inherent in individual payment mechanisms. However, mixed payment arrangements, which result in multiple funding flows from purchasers to providers, could be better understood by applying a systems approach that assesses the combined effects of multiple payment streams on healthcare providers. Guided by the framework developed by Barasa et al. (2021) (Barasa E, Mathauer I, Kabia E et al. 2021. How do healthcare providers respond to multiple funding flows? A conceptual framework and options to align them. Health Policy and Planning  36: 861-8.), this paper synthesizes the findings from six country case studies that examined multiple funding flows and describes the potential effect of multiple payment streams on healthcare provider behaviour in low- and middle-income countries. The qualitative findings from this study reveal the extent of undesirable provider behaviour occurring due to the receipt of multiple funding flows and explain how certain characteristics of funding flows can drive the occurrence of undesirable behaviours. Service and resource shifting occurred in most of the study countries; however, the occurrence of cost shifting was less evident. The perceived adequacy of payment rates was found to be the strongest driver of provider behaviour in the countries examined. The study results indicate that undesirable provider behaviours can have negative impacts on efficiency, equity and quality in healthcare service provision. Further empirical studies are required to add to the evidence on this link. In addition, future research could explore how governance arrangements can be used to coordinate multiple funding flows, mitigate unfavourable consequences and identify issues associated with the implementation of relevant governance measures.

Financial issues in times of a COVID-19 pandemic in a tertiary hospital in Mali.

BACKGROUND: This study examines how the functioning of healthcare providers during the COVID-19 pandemic was affected by the government financing response, which was shaped by existing healthcare financing systems. METHODS: The study applied a single case study design at a tertiary hospital in Bamako during the 1st and 2nd waves of the COVID-19 pandemic. Data were gathered through 51 in-depth interviews with hospital staff, participatory observation, and reviewing media articles and hospital financial records. RESULTS: The study revealed the disruptions experienced by hospital managers, human resources for health and patients in Mali during the early stages of the pandemic. While the government aimed to support universal access to COVID-19-related services, efforts were undermined by issues associated with complex public financing management procedures. The hospital experienced long delays in transferring government funds. The hospital suffered a decrease in revenue during the early stages of the pandemic. Government budgets were not effectively used because of complex, non-agile procedures that could not adapt to the emergency. The challenges faced by the hospitals led to the delays in the staff payments of salaries and promised bonuses, which created potential for unfair treatment of patients. Excluding some COVID-19 related items from the government funded benefit package created a financial burden on people receiving services. The managerial challenges experienced in the study hospital during the first wave continued in the second wave. CONCLUSIONS: Pre-existent issues in healthcare financing and governance constrained the effective management of COVID-19-related services and created confusion at the front line of healthcare service delivery.

Lessons Learned from Field Experiences on Hospitals' Resilience to the COVID-19 Pandemic: A Systematic Approach.

In this concluding article of the special issue, we examine lessons learned from hospitals' resilience to the COVID-19 pandemic in Brazil, Canada, France, Japan, and Mali. A quality lesson learned (QLL) results from a systematic process of collecting, compiling, and analyzing data derived ideally from sustained effort over the life of a research project and reflecting both positive and negative experiences. To produce QLLs as part of this research project, a guide to their development was drafted. The systematic approach we adopted to formulate quality lessons, while certainly complex, took into account the challenges faced by the different stakeholders involved in the fight against the COVID-19 pandemic. Here we present a comparative analysis of the lessons learned by hospitals and their staff with regard to four common themes that were the subject of empirical analyses: 1) infrastructure reorganization; 2) human resources management; 3) prevention and control of infection risk; and 4) logistics and supply. The lessons learned from the resilience of the hospitals included in this research indicate several factors to consider in preparing for a health crisis: 1) strengthening the coordination and leadership capacities of hospital managers and health authorities; 2) improving communication strategies; 3) strengthening organizational capacity; and 4) adapting resources and strategies, including for procurement and infection risk management.

Understanding factors influencing the use of clinical guidelines in low-income and middle-income settings: a scoping review.

OBJECTIVE: A scoping review was undertaken to determine the extent to which existing studies have examined factors influencing healthcare providers' use of clinical guidelines in low and middle-income country (LMIC) settings and determine which factors constrain or facilitate the use of clinical guidelines by healthcare providers. DESIGN: Scoping review. DATA SOURCES: The literature search was conducted using PubMed in January 2021. ELIGIBILITY CRITERIA: We identified empirical studies, published between 2011-2021 in English, which included clinicians and/or nurses as healthcare providers, used a health facility as the study site, and were located in an LMIC. DATA EXTRACTION AND SYNTHESIS: Information extracted from the literature review was organised using themes and the findings synthesised using thematic analysis. RESULTS: The review identified five types of interacting factors that influence healthcare providers' use of and compliance with clinical guidelines. The factors identified are organisational factors, factors relating to individual healthcare providers, attributes of the clinical guidelines, patient-related factors and institutional factors. Organisational factors can be further divided into the physical work environment, organisational culture and working conditions. The effective use of clinical guidelines in LMIC settings is greatly impacted by the contextualisation of clinical guidelines, end-user engagement and alignment of the implementation of clinical guidelines with the institutional arrangements in the broader health system. CONCLUSION: The development and evaluation of concrete interventions is vital to facilitate the implementation of clinical guidelines and improve healthcare service quality. Further studies are necessary to examine the relative importance of the five identified factors on the effective use of clinical guidelines in different contexts.

Factors for Consideration When Setting Prices for Private Healthcare Providers Operating in Public Systems: A Comparison of France and Japan.

Background: Most publicly-funded health systems purchase healthcare from private providers, but the optimal purchasing arrangements between public purchasers and private healthcare providers are yet to be determined. Objective: This study compares the healthcare purchasing arrangements made with private providers in 2 social health insurance (SHI)-based systems to identify factors that influence the prices paid for private healthcare service provision. Results: France and Japan use different approaches to determine the payment arrangements with public and private providers. The presence of for-profit healthcare providers in the French health system explains the different payment rates for public and private healthcare providers in that country. In both France and Japan, in addition to payment rates, several policy tools are used to assure the provision of public good services and the availability of necessary healthcare for all, which public providers are required to deliver but private providers can choose to deliver. Conclusion: This study highlights the importance of considering the profit-making status of the private healthcare providers operating in the healthcare market, and clarity in the roles and responsibilities of the public, for-profit and not-for-profit providers when determining healthcare purchasing arrangements. Regulatory policy instruments, used alongside payment rates, are essential to influence efficiency, equity, and quality in mixed (public-private) health systems.

Attributes and Organizational Factors that Enabled Innovation in Health Care Service Delivery during the COVID-19 Pandemic - Case Studies from Brazil, Canada and Japan.

Innovation by health service organizations can enable adaptation to and transformation of challenges caused by health shocks. Drawing on results from case studies in Brazil, Canada, and Japan, this study looked at innovations the study hospitals introduced in response to challenges caused by COVID-19 to identify: 1) attributes of the innovations that make them conducive to adoption; and 2) organizational factors that facilitate the creation and implementation of innovative health care approaches during health system shocks. Qualitative information was gathered using key informant interviews, participatory observations at the study hospitals and a review of relevant documentation. A thematic approach was used for analysis, and a cross-country comparison framework was prepared to synthesize findings from the case studies in the three countries. In response to the disruptions caused by COVID-19, the study hospitals undertook innovative changes in services, processes, organizational structures, and operational policy. The driving force behind the innovations was the need and urgency generated by the unprecedented nature of the pandemic. With COVID-19, if an innovation met the perceived needs of hospitals and provided an operational advantage, some level of complexity in the implementation appeared to be acceptable. The study findings suggest that for hospitals to create and implement innovations in response to health shocks, they need to: have adaptive and flexible organizational structures; build and maintain functioning communication systems; have committed leadership; ensure all staff share an understanding of hospital organizational and professional missions; and establish social networks that facilitate the creation and implementation of new ideas.

How Hospitals Overcame Disruptions in the Early Stages of the COVID-19 Pandemic: A Case Study from Tokyo, Japan.

The COVID-19 pandemic has caused serious disruptions to health systems across the world. While the pandemic has not ended, it is important to better understand the resilience of health systems by looking at the response to COVID-19 by hospitals and hospital staff. Part of a multi-country study, this study looks at the first and second waves of the pandemic in Japan and examines disruptions experienced by hospitals because of COVID-19 and the processes through which they overcame those disruptions. A holistic multiple case study design was employed, and two public hospitals were selected for the study. A total of 57 interviews were undertaken with purposively selected participants. A thematic approach was used in the analysis. The study found that in the early stages of the pandemic, faced with a previously unknown infectious disease, to facilitate the delivery of care to COVID-19 patients while also providing limited non-COVID-19 health care services, the case study hospitals undertook absorptive, adaptive, and transformative actions in the areas of hospital governance, human resources, nosocomial infection control, space and infrastructure management, and management of supplies. The process of overcoming the disruptions caused by the pandemic was complex, and the solution to one issue often caused other problems. To inform preparations for future health shocks and promote resilience, it is imperative to further investigate both organizational and broader health system factors that build absorptive, adaptive, and transformative capacity in hospitals.

A three-dimensional investigation of mandibular deviation in patients with mandibular prognathism.

BACKGROUND: Craniofacial disharmony in cases of jaw deformity associated with abnormal lateral deviation of the jaw mostly involves both the maxilla and mandible. However, it has been still difficult to capture the jaw deviation aspect in a 3-dimensional and quantitative techniques. In this study, we focused on 3-dimensional mandibular morphology and position of the condylar head in relation to the base of the skull in patients with mandibular prognathism, one of the most common jaw deformities. We used cluster analysis to quantify and classify deviation and clarified its characteristics. We also investigated the degree of correlation between those findings and menton (Me) deviation measured on frontal cephalograms, which is a conventional indicator of jaw deformity. RESULTS: Findings obtained from 100 patients (35 men, 65 women) were classified into the following three groups based on mandibular morphology and condylar position relative to the skull base. Then, reclassification using these parameters enabled classification of cluster analysis findings into seven groups based on abnormal jaw deviation characteristics. Comparison among these seven groups showed that the classification criteria were ramus height, mandibular body length, distance from the gonion to the apex of the coronoid process, and the lateral and vertical positions of the mandible. Weak correlation was also found between Me deviation on frontal cephalograms and each of the above parameters measured on 3D images. CONCLUSIONS: Focusing on mandibular morphology and condylar position relative to the skull base in patients with mandibular prognathism, we used cluster analysis to quantify and classify jaw deviation. The present results showed that the 3D characteristics of the mandible based on mandibular morphology and condylar position relative to the skull base can be classified into seven groups. Further, we clarified that Me deviation on frontal cephalograms, which has been used to date, is inadequate for capturing jaw deviation characteristics.

How should support for hospital staff during health shocks be improved? A discussion from Japan's experience during the COVID-19 pandemic.

Human resources for health are at the center of healthcare service delivery and play an important role in ensuring the resilience of health systems. Utilizing the results from a case study examining hospital resilience during COVID-19, this article draws on the experience of individual hospital staff during the first and second waves of the pandemic, briefly describes government responses to support human resources for health during the early stages of the pandemic, and argues the importance of constructive discussions about strategies to create an enabling work environment for healthcare providers, both clinical and non-clinical, during future health shocks.

Learning from public health and hospital resilience to the SARS-CoV-2 pandemic: protocol for a multiple case study (Brazil, Canada, China, France, Japan, and Mali).

BACKGROUND: All prevention efforts currently being implemented for COVID-19 are aimed at reducing the burden on strained health systems and human resources. There has been little research conducted to understand how SARS-CoV-2 has affected health care systems and professionals in terms of their work. Finding effective ways to share the knowledge and insight between countries, including lessons learned, is paramount to the international containment and management of the COVID-19 pandemic. The aim of this project is to compare the pandemic response to COVID-19 in Brazil, Canada, China, France, Japan, and Mali. This comparison will be used to identify strengths and weaknesses in the response, including challenges for health professionals and health systems. METHODS: We will use a multiple case study approach with multiple levels of nested analysis. We have chosen these countries as they represent different continents and different stages of the pandemic. We will focus on several major hospitals and two public health interventions (contact tracing and testing). It will employ a multidisciplinary research approach that will use qualitative data through observations, document analysis, and interviews, as well as quantitative data based on disease surveillance data and other publicly available data. Given that the methodological approaches of the project will be largely qualitative, the ethical risks are minimal. For the quantitative component, the data being used will be made publicly available. DISCUSSION: We will deliver lessons learned based on a rigorous process and on strong evidence to enable operational-level insight for national and international stakeholders.

How do healthcare providers respond to multiple funding flows? A conceptual framework and options to align them.

Provider payment methods are a key health policy lever because they influence healthcare provider behaviour and affect health system objectives, such as efficiency, equity, financial protection and quality. Previous research focused on analysing individual provider payment methods in isolation, or on the actions of individual purchasers. However, purchasers typically use a mix of provider payment methods to pay healthcare providers and most health systems are fragmented with multiple purchasers. From a health provider perspective, these different payments are experienced as multiple funding flows which together send a complex set of signals about where they should focus their effort. In this article, we argue that there is a need to expand the analysis of provider payment methods to include an analysis of the interactions of multiple funding flows and the combined effect of their incentives on the provision of healthcare services. The purpose of the article is to highlight the importance of multiple funding flows to health facilities and present a conceptual framework to guide their analysis. The framework hypothesizes that when healthcare providers receive multiple funding flows, they may find certain funding flows more favourable than others based on how these funding flows compare to each other on a range of attributes. This creates a set of incentives, and consequently, healthcare providers may alter their behaviour in three ways: resource shifting, service shifting and cost shifting. We describe these behaviours and how they may affect health system objectives. Our analysis underlines the need to align the incentives generated by multiple funding flows. To achieve this, we propose three policy strategies that relate to the governance of healthcare purchasing: reducing the fragmentation of health financing arrangements to decrease the number of multiple purchaser arrangements and funding flows; harmonizing signals from multiple funding flows; and constraining providers from responding to undesirable incentives.

Chemogenetic libraries, collections of well-defined chemical probes, provide tremendous value to biomedical research but require substantial effort to ensure diversity as well as quality of the contents. We have assembled a chemogenetic library by data mining and crowdsourcing institutional expertise. We are sharing our approach, lessons learned, and disclosing our current collection of 4,185 compounds with their primary annotated gene targets (https://github.com/Novartis/MoaBox). This physical collection is regularly updated and used broadly both within Novartis and in collaboration with external partners.

Examining purchasing reforms towards universal health coverage by the National Hospital Insurance Fund in Kenya.

BACKGROUND: Kenya has prioritized the attainment of universal health coverage (UHC) through the expansion of health insurance coverage by the National Hospital Insurance Fund (NHIF). In 2015, the NHIF introduced reforms in premium contribution rates, benefit packages, and provider payment methods. We examined the influence of these reforms on NHIF's purchasing practices and their implications for strategic purchasing and health system goals of equity, efficiency and quality. METHODS: We conducted an embedded case study with the NHIF as the case and the reforms as embedded units of analysis. We collected data at the national level and in two purposively selected counties through 41 in-depth interviews with health financing stakeholders, facility managers and frontline providers; 4 focus group discussions with 51 NHIF members; and, document reviews. We analysed the data using a Framework approach. RESULTS: The new NHIF reforms were characterized by weak purchasing actions. Firstly, the new premium contribution rates were inadequately communicated and unaffordable for certain citizen groups. Secondly, while the new benefit packages were reported to be based on service needs, preferences and values of the population, they were inadequately communicated and unequally distributed across different citizen groups. In addition, the presence of service delivery infrastructure gaps in public healthcare facilities and the pro-urban and pro-private distribution of contracted health facilities compromised delivery of, and access to, these new services. Lastly, the new provider payment methods and rates were considered inadequate, with delayed payments and weak links to financial accountability mechanisms which compromised their ability to incentivize equity, efficiency and quality of healthcare delivery. CONCLUSION: While NHIF sought to expand population and service coverage and reduce out-of-pocket payments with the new reforms, weaknesses in the reforms' design and implementation limited NHIF's purchasing actions with negative implications for the health system goals of equity, efficiency and quality. For the reforms to accelerate the country's progress towards UHC, policy makers at the NHIF and, national and county government should make deliberate efforts to align the design and implementation of such reforms with strategic purchasing actions that are aimed at improving health system goals.

Payment Arrangements for Private Healthcare Purchasing Under Publicly Funded Systems in Low- and Middle-Income Countries: Issues and Implications.

This paper examines private healthcare purchasing under publicly financed health systems in low- and middle-income countries (LMICs) to argue that the payment methods and rates applied to private and public health providers need careful attention to ensure equity, efficiency and quality in healthcare service provision. Specifically, public purchasers should develop a clear mechanism to establish justifiable payment rates for the purchase of private health services under publicly funded systems, using cost information and appropriate engagement with private health providers. In order to determine the validity of payment arrangements with private providers, clarification of the shared roles and responsibilities of public and private healthcare providers is required, including specification of types of services to be delivered by public and private providers, and the services for which public providers receive government budget and salaries above payments for other publicly funded services. In addition, carefully designed payment methods should include incentives to encourage healthcare providers to deliver efficient, equitable and quality health services, which requires consideration of how the healthcare purchasing market is structured. Furthermore, governments should establish sound legal frameworks to ensure that public purchasers establish 'strategic' payment arrangements with healthcare providers and that healthcare providers are able to respond to the incentives sent by the payment arrangements. To deepen understanding of public purchasing of private healthcare services and gain further insight in the LMIC context, in-depth empirical studies are necessary on the payment methods and rates used by public purchasers in a range of settings and the implications of payment arrangements on efficiency, equity and quality in healthcare service provision.

Strategic Purchasing: The Neglected Health Financing Function for Pursuing Universal Health Coverage in Low-and Middle-Income Countries Comment on "What's Needed to Develop Strategic Purchasing in Healthcare? Policy Lessons from a Realist Review".

Sanderson et al's realist review of strategic purchasing identifies insights from two strands of theory: the economics of organisation and inter-organisational relationships. Our findings from a programme of research conducted by the RESYST (Resilient and Responsive Health Systems) consortium in seven countries echo these results, and add to them the crucial area of organisational capacity to implement complex reforms. We identify key areas for policy development. These are the need for: (1) a policy design with clearly delineated responsibilities; (2) a task network of organisations to engage in the broad set of functions needed; (3) more effective means of engaging with populations; (4) a range of technical and management capacities; and (5) an awareness of the multiple agency relationships that are created by the broader financing environment and the provider incentives generated by multiple financing flows.

For more than money: willingness of health professionals to stay in remote Senegal.

BACKGROUND: Poor distribution of already inadequate numbers of health professionals seriously constrains equitable access to health services in low- and middle-income countries. The Senegalese Government is currently developing policy to encourage health professionals to remain in areas defined as 'difficult'. Understanding health professional's preferences is crucial for this policy development. METHODS: Working with the Senegalese Government, a choice experiment (CE) was developed to elicit the job preferences of physicians and non-physicians. Attributes were defined using a novel mixed-methods approach, combining interviews and best-worst scaling (Case 1). Six attributes were categorised as 'individual (extrinsic) incentive' attributes ('type of contract', 'provision of training opportunities', 'provision of an allowance' and 'provision of accommodation') or 'functioning health system' attributes ('availability of basic equipment in health facilities' and 'provision of supportive supervision by health administrators'). Using face-to-face interviews, the CE was administered to 55 physicians (3909 observations) and 246 non-physicians (17 961 observations) randomly selected from those working in eight 'difficult' regions in Senegal. Conditional logit was used to analyse responses. This is the first CE to both explore the impact of contract type on rural retention and to estimate value of attributes in terms of willingness to stay (WTS) in current rural post. RESULTS: For both physicians and non-physicians, a permanent contract is the most important determinant of rural job retention, followed by availability of equipment and provision of training opportunities. Retention probabilities suggest that policy reform affecting only a single attribute is unlikely to encourage health professionals to remain in 'difficult' regions. The relative importance of an allowance is low; however, the level of such financial incentives requires further investigation. CONCLUSION: Contract type is a key factor impacting on retention. This has led the Senegalese Health Ministry to introduce a new rural assignment policy that recruits permanent staff from the pool of annually contracted healthcare professionals on the condition that they take up rural posts. While this is a useful policy development, further efforts to retain rural health workers, considering both personal incentives and the functioning of health systems, are necessary to ensure health worker numbers are adequate to meet the needs of rural communities.

Strategic purchasing for universal health coverage: examining the purchaser-provider relationship within a social health insurance scheme in Nigeria.

BACKGROUND: In an attempt to achieve universal health coverage, Nigeria introduced a number of health insurance schemes. One of them, the Formal Sector Social Health Insurance Programme (FSSHIP), was launched in 2005 to provide health cover to federal government and formal private sector employees. It operates with two levels of purchasers, the National Health Insurance Scheme (NHIS) and health maintenance organisations (HMOs). This study critically assesses purchasing arrangements between NHIS, HMOs and healthcare providers and determines how the arrangements function from a strategic purchasing perspective within the FSSHIP. METHODS: A qualitative study undertaken in Enugu state, Nigeria, data were gathered through reviews of documents, 17 in-depth interviews (IDIs) with NHIS, HMOs and healthcare providers and two focus group discussions (FGDs) with FSSHIP enrolees. A strategic purchasing lens was used to guide data analysis. RESULTS: The purchasing function was not being used strategically to influence provider behaviour and improve efficiency and quality in healthcare service delivery. For the purchaser-provider relationship, these actions are: accreditation of healthcare providers; monitoring of HMOs and healthcare providers and use of appropriate provider payment mechanisms for healthcare services at every level. The government lacks resources and political will to perform their stewardship role while provider dissatisfaction with payments and reimbursements adversely affected service provision to enrolled members. Underlying this inability to purchase, health services strategically is the two-tiered purchasing mechanism wherein NHIS is not adequately exercising its stewardship role to monitor and guide HMOs to fulfil their roles and responsibilities as purchasing administrators. CONCLUSIONS: Purchasing under the FSSHIP is more passive than strategic. Governance framework requires strengthening and clarity for optimal implementation so as to ensure that both levels of purchasers undertake strategic purchasing actions. Additional strengthening of NHIS is needed for it to have capacity to play its stewardship role in the FSSHIP.

Effect of Lorenzo's Oil on Hepatic Gene Expression and the Serum Fatty Acid Level in abcd1-Deficient Mice.

Lorenzo's oil is known to decrease the saturated very long chain fatty acid (VLCFA) level in the plasma and skin fibroblasts of X-linked adrenoleukodystrophy (ALD) patients. However, the involvement of Lorenzo's oil in in vivo fatty acid metabolism has not been well elucidated. To investigate the effect of Lorenzo's oil on fatty acid metabolism, we analyzed the hepatic gene expression together with the serum fatty acid level in Lorenzo's oil-treated wild-type and abcd1-deficient mice. The change in the serum fatty acid level in Lorenzo's oil-treated abcd1-defcient mice was quite similar to that in the plasma fatty acid level in ALD patients supplemented with Lorenzo's oil. In addition, we found that the hepatic gene expression of two peroxisomal enzymes, Dbp and Scp2, and three microsomal enzymes, Elovl1, 2, and 3, were significantly stimulated by Lorenzo's oil. Our findings indicate that Lorenzo's oil activates hepatic peroxisomal fatty acid ß-oxidation at the transcriptional level. In contrast, the transcriptional stimulation of Elovl1, 2, and 3 by Lorenzo's oil does not cause changes in the serum fatty acid level. It seems likely that the inhibition of these elongation activities by Lorenzo's oil results in a decrease in saturated VLCFA. Thus, these results not only contribute to a clarification of the mechanism by which the saturated VLCFA level is reduced in the serum of ALD patients by Lorenzo's oil-treatment, but also suggest the development of a new therapeutic approach to peroxisomal ß-oxidation enzyme deficiency, especially mild phenotype of DBP deficiency.
