The genesis of the PM-JAY health insurance scheme in India: technical and political elements influencing a national reform towards universal health coverage.

Many countries are using health insurance to advance progress towards universal health coverage (UHC). India launched the Pradhan Mantri Jan Arogya Yojana (PM-JAY) health insurance scheme in 2018. We examine the political economy context around PM-JAY policy formulation, by examining the perspectives of policy stakeholders shaping decisions around the reform. More specifically, we focus on early policy design at the central (national) level. We use a framework on the politics of UHC reform proposed by Fox and Reich (The politics of universal health coverage in low- and middle-income countries: A framework for evaluation and action. J. Health Polit. Policy Law 2015;40:1023-1060), to categorize the reform into phases and examine the interactions between actors, institutions, interests, ideas and ideology which shaped reform decisions. We interviewed 15 respondents in Delhi between February and April 2019, who were either closely associated with the reform process or subject experts. The ruling centre-right government introduced PM-JAY shortly before national elections, drawing upon policy legacies from prior and state insurance schemes. Empowered policy entrepreneurs within the government focused discourse around ideas of UHC and strategic purchasing, and engaged in institution building leading to the creation of the National Health Authority and State Health Agencies through policy directives, thereby expanding state infrastructural and institutional power for insurance implementation. Indian state inputs were incorporated in scheme design features like mode of implementation, benefit package and provider network, while features like the coverage amount, portability of benefits and branding strategy were more centrally driven. These balanced negotiations opened up political space for a cohesive, central narrative of the reform and facilitated adoption. Our analysis shows that the PM-JAY reform focused on bureaucratic rather than ideological elements and that technical compromises and adjustments accommodating the interests of states enabled the political success of policy formulation. Appreciating these politics, power and structural issues shaping PM-JAY institutional design will be important to understand how PM-JAY is implemented and how it advances UHC in India.

Assessment of SARS-CoV-2 airborne infection transmission risk in public buses.

Public transport environments are thought to play a key role in the spread of SARS-CoV-2 worldwide. Indeed, high crowding indexes (i.e. high numbers of people relative to the vehicle size), inadequate clean air supply, and frequent extended exposure durations make transport environments potential hotspots for transmission of respiratory infections. During the COVID-19 pandemic, generic mitigation measures (e.g. physical distancing) have been applied without also considering the airborne transmission route. This is due to the lack of quantified data about airborne contagion risk in transport environments. In this study, we apply a novel combination of close proximity and room-scale risk assessment approaches for people sharing public transport environments to predict their contagion risk due to SARS-CoV-2 respiratory infection. In particular, the individual infection risk of susceptible subjects and the transmissibility of SARS-CoV-2 (expressed through the reproduction number) are evaluated for two types of buses, differing in terms of exposure time and crowding index: urban and long-distance buses. Infection risk and reproduction number are calculated for different scenarios as a function of the ventilation rates (both measured and estimated according to standards), crowding indexes, and travel times. The results show that for urban buses, the close proximity contribution significantly affects the maximum occupancy to maintain a reproductive number of <1. In particular, full occupancy of the bus would be permitted only for an infected subject breathing, whereas for an infected subject speaking, masking would be required. For long-distance buses, full occupancy of the bus can be maintained only if specific mitigation solutions are simultaneously applied. For example, for an infected person speaking for 1 h, appropriate filtration of the recirculated air and simultaneous use of FFP2 masks would permit full occupancy of the bus for a period of almost 8 h. Otherwise, a high percentage of immunized persons (>80%) would be needed.

Oral Health Status and Oral Health-Related Quality of Life of First Nations and Metis Children.

OBJECTIVES: To assess the oral health status and oral health-related quality of life (OHRQoL) of young First Nations and Metis children. METHODS: This cross-sectional study assessed the oral health status of Indigenous children <72 mo of age while their parents/caregivers completed a questionnaire, including the Early Childhood Oral Health Impact Scale (ECOHIS), to assess OHRQoL. Analysis included descriptive statistics, bivariate analyses, and multiple regression. A P value ≤0.05 was considered significant. RESULTS: Overall, 146 children were recruited with a mean age of 40.1 ± 21.2 (SD) months, and 49% were male. Among First Nations children, 65.4% had early childhood caries (ECC) as compared with 45.2% among Metis children (P = 0.025). However, there was no statistically significant difference in the prevalence of severe ECC (S-ECC) between First Nations and Metis children (60.6% v. 42.9%, P = 0.051). The mean decayed, missing, and filled primary teeth (dmft) score was 4.9 ± 5.3 (range 0-20), and the mean decayed, missing, and filled surfaces (dmfs) score was 14.5 ± 20.4 (range 0-80). The total mean ECOHIS score was 4.4 ± 5.9 (range 0-25), while the mean Child Impact Section and Family Impact Section scores were 2.6 ± 4.0 (range 0-10) and 1.8 ± 2.8 (range 0-8), respectively. Multiple linear regression showed S-ECC was associated with total mean ECOHIS scores (P = 0.02). Higher total mean ECOHIS scores (which indicates poorer OHRQoL) were observed in children with ECC compared with caries-free children (5.8 v. 2.4, P = 0.0001). CONCLUSION: Oral health disparities such as ECC and reduced OHRQoL exist among many First Nations and Metis children in Manitoba. This is the first Canadian study exploring the OHRQoL of Indigenous children in addition to their oral health status. KNOWLEDGE TRANSFER STATEMENT: This study is the first to report on the oral health-related quality of life and its relationship to early childhood caries (ECC) among young Canadian First Nations and Metis children. Metis children are just as likely to suffer from severe ECC than First Nations children. The findings of this study have informed community-based and community-developed oral health promotion and ECC prevention activities.

Parents' Views on Silver Diamine Fluoride to Manage Early Childhood Caries.

BACKGROUND: The use of silver diamine fluoride (SDF) as a nonsurgical caries management product is growing. Evidence suggests that SDF is very successful in arresting caries. However, a common concern with SDF treatment is the unaesthetic black staining. The purpose of this qualitative study was to determine parents' views following their children's treatment with SDF to manage severe early childhood caries (ECC). METHOD: Parents were interviewed as part of a mixed-method study of SDF to arrest severe ECC. Children with caries lesions in primary teeth were treated with 2 applications of 38% SDF, followed by fluoride varnish. Semistructured in-person and phone interviews were conducted with 19 parents of children in the study. Data were transcribed verbatim and manually coded and uploaded to NVivo 12 for further coding analysis. RESULTS: None of the parents had previously heard about SDF, and they learned about it from the study dentist. Although parents trusted the dentist's information on SDF, they welcomed additional evidence, especially relating to product safety and effectiveness. Some parents were minimally concerned with the black staining caused by SDF treatment. It was more important that SDF arrested caries progression, minimized pain and sensitivity, and prevented dental infection. However, some parents expressed concerns related to the unaesthetic black staining. Interestingly, many parents indicated that their children were not overly concerned with the black staining. A majority of parents said that they would recommend the treatment to others. CONCLUSION: This is the first qualitative study involving parents of children who were treated with SDF. Most parents were accepting of SDF as a nonsurgical treatment to arrest caries and minimize dentinal sensitivity secondary to caries, although some expressed concern about the black staining in anterior teeth. It is important to adequately inform parents of the negative aesthetic consequences and obtain informed consent before treatment. KNOWLEDGE TRANSFER STATEMENT: This qualitative study revealed that many parents of children with severe ECC are accepting of SDF as a nonrestorative caries management option, despite the black staining of caries lesions. Dental professionals need to be aware of these parental concerns and obtain written informed consent prior to treatment. Parents also requested more information and resources on SDF on its benefits, effectiveness, and any associated risks.

Evaluation of the efficacy and tolerability of a solution containing propyl betaine and polihexanide for wound irrigation.

Wound cleansing represents a fundamental step in chronic wound management. Several investigations in recent years have led to a refinement of the wound cleansing protocol in order to obtain a better control of the bacterial burden during wound bed preparation and to avoid further cell and tissue damage. The aim of the present randomized controlled trial was to investigate the effects of a wound cleansing solution containing polihexanide and betaine in venous leg ulcers by means of clinical and instrumental assessment. A portable device was used on the wound bed to assess surface pH, which has been shown to be one of the most useful non-invasive biophysical parameters in order to correlate the level of bacterial burden in different types of chronic wounds. Baseline pH on the wound surface (median range) was initially 8.9, and after 4 weeks of cleansing treatment and moist wound dressing was reduced and stable at 7.0 in the group treated with active cleanser. The pH value was significantly lower (p < 0.05) in this group compared to the control group at the end of the study. The treatment with the solution containing polihexanide and betaine was well tolerated by the patients and was found useful in the absorption of wound odours.

Quantification of the human granulocytic ehrlichiosis agent based on analysis of rRNA isolated from control and infected HL-60 cells.

Human granulocytic ehrlichiosis (HGE) is an emerging vector-borne disease caused by an Ehrlichia species similar or identical to E. equi and E. phagocytophila. Previous studies have shown that the pathogen can be cultivated in vitro in permissive cells such as human promyelocytic HL-60 leukemia cells. The mechanism(s) of its infection and propagation in target cells, however, is not well understood, due in part to lack of a method capable of quantitatively determining the amount of the infectious agent. Although several assays currently exist for the HGE agent, they are mostly qualitative and have a number of limitations. In this report, size differences between prokaryotic and eukaryotic rRNAs are utilized to quantitatively assay the HGE agent in HL-60 cells. By comparing the integrated intensity of agarose gel resolved HGE-specific rRNA in host cells, with identically prepared and analyzed rRNA isolated from known quantities of E. coli (JM 109), it is possible to calculate the E. coli-equivalence of the HGE agent present in HL-60 cells according to the equation: Y (E. coli, in viable cells x 10(8)) = -2.573 + 0.11X (% infection by the HGE agent in HL-60 cells). The method described is reproducible, sensitive, and is not limited by availability of antisera. Furthermore, since the assay has no designer primer and repeated amplification requirements, it can be easily disseminated to and standardized in other laboratories.
