RESUMO

Background & objectives: Investment in mental health is quite meagre worldwide, including in India. The costs of new interventions must be clarified to ensure the appropriate utilization of available resources. The government of Gujarat implemented QualityRights intervention at six public mental health hospitals. This study was aimed to project the costs of scaling up of the Gujarat QualityRights intervention to understand the additional resources needed for a broader implementation. Methods: Economic costs of the QualityRights intervention were calculated using an ingredients-based approach from the health systems' perspective. Major activities within the QualityRights intervention included assessment visits, meetings, training of trainers, provision of peer support and onsite training. Results: Total costs of implementing the QualityRights intervention varied from Indian Rupees (₹) 0.59 million to ₹ 2.59 million [1United States Dollars (US $) = ₹ 74.132] across six intervention sites at 2020 prices with 69-79 per cent of the cost being time cost. Scaling up the intervention to the entire State of Gujarat would require about two per cent increase in financial investment, or about 7.5 per cent increase in total cost including time costs over and above the costs of usual care for people with mental health conditions in public health facilities across the State. Interpretation & conclusions: The findings of this study suggest that human resources were the major cost contributor of the programme. Given the shortage of trained human resources in the mental health sector, appropriate planning during the scale-up phase of the QualityRights intervention is required to ensure all staff members receive the required training, and the treatment is not compromised during this training phase. As only about two per cent increase in financial cost can improve the quality of mental healthcare significantly, the State government can plan for its scale-up across the State.

RESUMO

BACKGROUND: The nationwide lockdown (March 25 to June 8, 2020) to curb the spread of coronavirus infection had significant health and economic impacts on the Indian economy. There is limited empirical evidence on how COVID-19 restrictive measures may impact the economic welfare of specific groups of patients, e.g., tuberculosis patients. We provide the first such evidence for India. METHODS: A total of 291 tuberculosis patients from the general population and from a high-risk group, patients from tea garden areas, were interviewed at different time points to understand household income loss during the complete lockdown, three and eight months after the complete lockdown was lifted. Income loss was estimated by comparing net monthly household income during and after lockdown with prelockdown income. Tuberculosis service utilization patterns before and during the lockdown period also were examined. Household income loss, travel and other expenses related to tuberculosis drug pickup were presented in 2020 US dollars (1 US$ = INR 74.132). RESULTS: 26% of households with tuberculosis patients in tea garden areas and 51% of households in the general population had zero monthly income during the complete lockdown months (April-May 2020). Overall income loss slowly recovered during July-August compared to April-May 2020. Approximately 7% of patients in the general population and 4% in tea garden areas discontinued their tuberculosis medicines because of the complete lockdown. CONCLUSION: Discontinuation of medicine will have an additional burden on the tuberculosis elimination program in terms of additional cases, including multidrug resistant tuberculosis cases. Income loss for households and poor restoration of income after the lockdown will likely have an impact on the nutrition of tuberculosis patients and families. Tuberculosis patients working in the informal sector were the worst affected group during the nationwide lockdown. This emphasizes that a policy priority must continue to protect those working in informal sectors from the economic consequences of such restrictive measures, including paid sick leave, additional food support, and direct benefit transfers. Alongside ensuring widespread access to COVID-19 vaccines, these policy actions remain pivotal in ensuring the well-being of those who are unfortunate enough to be living with tuberculosis.

RESUMO

The increased risks of storm flood occurrences in large cities are the result of land use changes due to rapid urbanization. This study examines the influence of land use changes in Khulna City Corporation (KCC) area on surface runoff over a period of 15 years, from 2005 to 2020. Land use-land cover (LULC) maps for 2005, 2010, 2015, and 2020 were created employing support vector machine (SVM)-based supervised image classification using time-series satellite data, and the surface runoff was determined using Soil Conservation Service-Curve Number model. The major land use change drivers of surface runoff were determined through a correlation analysis. Surface runoff was observed to follow a similar trend as that of impervious urban areas, which went up by 5.44% from 2005 to 2020 (17.00 mm increment in average runoff) and the opposite trend was found in vegetation land cover, which declined by 13.34% in areal extent throughout the study period. In comparison with other types of land use, surface runoff changes were most significantly associated with the changes in urban impervious areas and vegetation land use-land cover (LULC) class. In fast-growing cities across the world, and especially in developing nations, the results of this study may serve as a guide for urban storm flood management and urban planning efforts.

RESUMO

Congenital myotonia represents a rare group of genetically inherited conditions. It can be either autosomal dominant (Thomsen) or autosomal recessive (Becker). It is characterized by muscular hypertrophy, proximal weakness, and myotonia, or impaired relaxation after contraction. These are due to mutations in the CLC1 gene. A 14-year-old male child presented with complaints of gradually progressive weakness for five years. Weakness was more pronounced in the proximal muscle groups. The weakness worsened after rest and improved with activity. This led to absenteeism and affected his school performance. Clinical examination showed generalized muscular hypertrophy with pronounced hypertrophy of the calf muscles. A neurological examination showed significant myotonia and impaired relaxation after making a fist. The diagnosis of myotonia was confirmed by electromyography, which produced a dive-bomber sound on insertion. Next-generation sequencing revealed a homozygous eight-base pair insertion in exon 19 of the CLCN1 gene. This mutation has not been reported in the existing literature for myotonia congenita. The child was started on mexiletine and improved significantly. Presently, the patient is on regular medications and doing well on follow-up. Though rare, congenital myotonia is an important cause of neuromuscular weakness. It can be easily diagnosed with a thorough clinical examination and routine testing for myotonia in all children with weakness. The treatment is relatively simple and can give the patient significant relief. Myotonia can be easily diagnosed clinically, and pharmacotherapy and proper monitoring can remarkably improve patients' quality of life.

RESUMO

This study presents a 2D comprehensive analytical and numerical analysis of the thermomechanical stresses in an unsymmetric dual compound thick cylinder under steady-state conditions. By employing mathematical analysis, this research aims to investigate the effectiveness of a 2D compound cylinder in reducing elastic and thermoelastic stresses. The temperature and displacement fields are thought to be dependent on the radial and circumferential directions, subject to asymmetric thermal and mechanical boundary conditions on the inner and outer surfaces. In this scenario, the Poisson ratio is considered to be a constant. The techniques of variable separation and complex Fourier series are employed analytically in the solution of heat conduction and Navier equations. The results obtained from the developed analytical method are compared and validated against those obtained from a finite difference method (FDM). The findings of this study suggest that the clamping of the outer layer has a significant influence on stress distribution in the structure, and the impact of tangential stress on the behavior of a compound cylinder is highly dominant. Furthermore, changes in temperature significantly influence hoop stress compared to variations in internal pressure levels. Moreover, the influence of internal pressure is relatively attenuated when a pressure vessel is fabricated utilizing different metals. In addition, the findings indicated that the configuration of layers and the location of the highest temperature had a significant impact on the performance of the vessel. Nevertheless, the technology provided has sufficient robustness to effectively address the complexities associated with the design of multilayered graded materials (GM) in additive manufacturing applications.

RESUMO

Providing social support to tuberculosis (TB) patients is a recommended strategy as households having TB patients find themselves in a spiral of poverty because of high cost, huge income loss and several other economic consequences associated with TB treatment. However, there are few examples of social support globally. The Indian government introduced "Nikshay Poshan Yojana" scheme in 2018 to provide nutritional support for all registered TB patients. Financial incentive of Indian Rupee (INR) 500 (US$6) per month was proposed to be transferred directly to the registered beneficiaries' validated bank accounts. We examined the reach, timing, amount of benefit receipt, and the extent to which the benefit alleviated catastrophic costs (used as a proxy to measure the impact on permanent economic welfare as catastrophic cost is the level of cost that is likely to result in a permanent negative economic impact on households) by interviewing 1482 adult drug-susceptible TB patients from 16 districts of four states during 2019 to 2023, using the methods recommended by the World Health Organisation for estimating household costs of TB nationally. We also estimated the potential amount of social support required to achieve a zero catastrophic cost target. At the end of treatment, 31%-54% study participants received the benefit. 34%-60% of TB patients experienced catastrophic costs using different estimation methods and the benefit helped 2% study participants to remain below the catastrophic cost threshold. A uniform benefit amount of INR 10000 (US$127) for 6 months of treatment could reduce the incidence of catastrophic costs by 43%. To improve economic welfare of TB patients, levels of benefit need to be substantially increased which will have considerable budgetary impact on the TB programme. Hence, a targeted rather than universal approach may be considered. To maximise impact, at least half of the revised amount should be given immediately after treatment registration.

RESUMO

Multi-system inflammatory syndrome in children associated with COVID19 (MIS-C) is a unique clinical syndrome characterised by fever, gastrointestinal symptoms, skin and oral rash and or neurological symptoms in the presence of raised acute phase reactants and coagulopathy. Ferritin is an acute phase reactant which is used as a marker of inflammation. Diagnosis of MIS-C in the background of transfusion dependent thalassemia with iron overload needs a strong clinical suspicion. Early diagnosis and prompt treatment are necessary to ensure a rapid uneventful recovery. A three-year-old male child born to non-consanguineously related parents reported to pediatric emergency with difficulty breathing and pain abdomen for one day. The child was a diagnosed case of Beta thalassemia major since the age of one year and was on regular transfusions and was on iron chelation for past eleven months with deferrasirox. Initial clinical examination showed a sick and irritable child with tachypnea tachycardia and hypoxia. Initial investigations showed raised acute phase reactants along with severe anemia. The child was investigated for MIS-C because of unexpected rise of serum ferritin from 1980 ng/mL (October 2020) to 6686 ng/mL (in January 2021) despite being on regular chelation. Antibody titre for SARS COVID-19 was positive. The patient was treated with intravenous corticosteroids and improved with the same. The advent of COVID19 pandemic saw most children having a mild disease with no or minimal symptoms. Some kids however presented with more serious delayed symptoms of MIS-C. To diagnose same in multi transfused patients a strong clinical suspicion and just judgement based on the clinical and laboratory findings should be done. Unexplained rise in ferritin levels, typical symptoms and high probability of exposure to COVID19 helped in clinching diagnosis.

RESUMO

As financial risk protection is one of the goals towards universal health coverage, detailed information on costs, catastrophic costs and other economic consequences related to any disease are required for designing social protection measures. End Tuberculosis (TB) Strategy set a milestone of achieving zero catastrophic cost by 2020. However, a recent literature review noted that 7%-32% TB affected households in India faced catastrophic cost. Studies included in the review were small scale cross-sectional. We followed a cohort of 1482 notified drug-susceptible TB patients from four states in India: Assam, Maharashtra, Tamil Nadu, and West Bengal to provide a comprehensive picture of economic burden associated with TB treatment. Treatment cost was calculated using World Health Organization guidelines on TB patient cost survey and both human capital and output approaches of indirect cost (time, productivity, and income loss related to an episode) calculation were used to provide the range of households currently facing catastrophic cost. Depending on choice of indirect cost calculation method, 30%-61% study participants faced catastrophic cost. For over half of them, costs became catastrophic even before starting TB treatment as there was average 7-9 weeks delay from symptom onset to treatment initiation which was double the generally accepted delay of 4 weeks. During that period, they made average 8-11 visits to different providers and spent money on consultations, drugs, tests, and travel. Following the largest cohort of drug-susceptible TB patients till date, the study concluded that a significant proportion of study participants faced catastrophic cost and the proportion was much higher when income loss was considered as indirect cost calculation method. Therefore, ensuring uninterrupted livelihood during TB treatment is an absolute necessity. Another reason of high cost was the delay in diagnosis and costs incurred during pre-diagnosis period. This delay and consequently, economic burden, can be reduced by both supply side (intense private sector engagement, rapid diagnosis) and demand side (community engagement) initiatives. Reimbursement of expenses incurred before treatment initiation could be used as short-term measure for mitigating financial hardship.

RESUMO

The aim of the study was to estimate future groundwater potential zones based on machine learning algorithms and climate change scenarios. Fourteen parameters (i.e., curvature, drainage density, slope, roughness, rainfall, temperature, relative humidity, lineament density, land use and land cover, general soil types, geology, geomorphology, topographic position index (TPI), topographic wetness index (TWI)) were used in developing machine learning algorithms. Three machine learning algorithms (i.e., artificial neural network (ANN), logistic model tree (LMT), and logistic regression (LR)) were applied to identify groundwater potential zones. The best-fit model was selected based on the ROC curve. Representative concentration pathways (RCP) of 2.5, 4.5, 6.0, and 8.5 climate scenarios of precipitation were used for modeling future climate change. Finally, future groundwater potential zones were identified for 2025, 2030, 2035, and 2040 based on the best machine learning model and future RCP models. According to findings, ANN shows better accuracy than the other two models (AUC: 0.875). The ANN model predicted that 23.10 percent of the land was in very high groundwater potential zones, whereas 33.50 percent was in extremely high groundwater potential zones. The study forecasts precipitation values under different climate change scenarios (RCP2.6, RCP4.5, RCP6, and RCP8.5) for 2025, 2030, 2035, and 2040 using an ANN model and shows spatial distribution maps for each scenario. Finally, sixteen scenarios were generated for future groundwater potential zones. Government officials may utilize the study's results to inform evidence-based choices on water management and planning at the national level.

RESUMO

Context: ß-thalassemia trait is usually diagnosed by raised hemoglobin A2 (HbA2). The presence of megaloblastic anemia can cause an increase in HbA2 and create a diagnostic dilemma. Here, we have analyzed the effect of vitamin B12 and folic acid supplementation on HbA2 and diagnosis of ß-thalassemia trait in cases of megaloblastic anemia with raised HbA2. Materials and Methods: Cases of megaloblastic anemia with raised HbA2 on high-performance liquid chromatography (HPLC) were supplemented with vitamin B12 and folic acid. Post-treatment evaluation was done after 2 months. Cases showing adequate hematological response were subjected to statistical analysis. Based on post-treatment HbA2 value, the cases were diagnosed as normal, borderline raised HbA2, or ß-thalassemia trait. Pre- and post-treatment values of red cell parameters and HbA2 were analyzed. Results: There was a significant decrease in HbA2 value after vitamin B12 and folic acid supplementation. The diagnosis was changed in 70.97% of the cases after treatment. The chance of inconclusive diagnosis was decreased from more than 50% to less than 10%. Pre-treatment mean corpuscular volume (MCV) and HbA2% showed a significant difference between the thalassemic and normal groups. Conclusions: Megaloblastic anemia can lead to false-positive diagnosis of ß-thalassemia trait on HPLC. Repeat HPLC should be done after adequate supplementation of vitamin B12 and folic acid in cases of megaloblastic anemia with raised HbA2. Red cell parameters are not helpful to suspect ß-thalassemia trait in presence of megaloblastic anemia. However, HbA2% on HPLC can be a useful parameter to suspect or exclude ß-thalassemia trait in cases of megaloblastic anemia.

RESUMO

Historically, economic studies on tuberculosis estimated out-of-pocket expenses related to tuberculosis treatment and catastrophic cost, however, no study has yet been conducted to understand the post-treatment economic conditions of the tuberculosis patients in India. In this paper, we add to this body of knowledge by examining the experiences of the tuberculosis patients from the onset of symptoms till one-year post-treatment. 829 adult drug-susceptible tuberculosis patients from general population and from two high risk groups: urban slum dwellers and tea garden families were interviewed during February 2019 to February 2021 at their intensive and continuation phases of treatment and about one-year post-treatment using adapted World Health Organization tuberculosis patient cost survey instrument. Interviews covered socio-economic conditions, employment status, income, out-of-pocket expenses and time spent for outpatient visits, hospitalization, drug-pick up, medical follow-ups, additional food, coping strategies, treatment outcome, identification of post-treatment symptoms and treatment for post-treatment sequalae/recurrent cases. All costs were calculated in 2020 Indian rupee (INR) and converted into US dollar (US$) (1 US$ = INR 74.132). Total cost of tuberculosis treatment since the onset of symptom till one-year post-treatment ranged from US$359 (Standard Deviation (SD) 744) to US$413 (SD 500) of which 32%-44% of costs incurred in pre-treatment phase and 7% in post-treatment phase. 29%-43% study participants reported having outstanding loan with average amount ranged from US $103 to US$261 during the post-treatment period. 20%-28% participants borrowed during post-treatment period and 7%-16% sold/mortgaged personal belongings. Therefore, economic impact of tuberculosis persists way beyond treatment completion. Major reasons of continued hardship were costs associated with initial tuberculosis treatment, unemployment, and reduced income. Therefore, policy priorities to reduce treatment cost and to protect patients from the economic consequences of the disease by ensuring job security, additional food support, better management of direct benefit transfer and improving coverage through medical insurances need consideration.

RESUMO

In developing nations, limitations in diagnostic facilities act as a barrier for differentiation of hemolytic uremic syndrome (HUS) based on the etiology. A sick-looking 18-month-old boy presented to our hospital in Bhubaneswar, India, with clinical signs and symptoms of left lobar pneumonia, abnormal hematological and renal parameters, no growth in blood culture, a negative direct antiglobulin test (DAT) result, and low complement levels. A rapid deterioration in his clinical condition necessitated intensive care support, blood transfusion, and renal replacement therapy (peritoneal dialysis and hemodialysis). Because his health care team suspected atypical HUS, therapeutic plasma exchange (TPE) was initiated as soon as possible. In the absence of a lectin panel, minor cross-matching confirmed T-antigen exposure. With a diagnosis of HUS induced by Streptococcus pneumoniae (sp-HUS), TPE was stopped immediately, and washed blood components were administered. Despite the aforementioned measures, the boy died of HUS on day 20 after presentation. This case emphasized the role of minor cross-matching in the detecting of polyagglutination in resolving the diagnostic dilemma of sp-HUS.

RESUMO

An investigation was carried out in order to develop an accurate analytical solution and a numerical (FEA) solution for steady-state heat transfer in a circular sandwich structure incorporated with convective-radiative boundary conditions. The dimensional governing equations and boundary conditions were developed in the form of a 4th order algebraic equation, and then the solution was obtained using Ferrari's method. By solving for the roots of the quartic equation, we were able to determine the dimensionless temperature fields of the FG sandwich composite. The findings obtained utilizing the exact analytical solution for the FG sandwich composite under thermal loads were satisfactorily validated against those data obtained using the Galerkin finite element approximation. The impact of geometric and thermo-physical characteristics, such as Biot number (Bii=1,2), Inner and outer surface thickness ratio (ri=1,2Ro), ambient temperature ratio (θd), radiation-conduction parameter (Nr), and thermal conductivity ratio (λ3λ1) on the efficiency of heat transfer, has also been studied. This study reveals the distinct effect of Biot number on the inner and outer layers of the composite cylinder. It shows that Bi1 has a negligent effect on temperature distribution; on the other hand, the outer surface (Bi2≤1) minimizes temperature variation. However, for design consideration, a thicker inner face sheet is not recommended in high thermal load, as Nr>4 has an insignificant impact on inner surface thickness on top surface temperature. Moreover, the outer surface temperature appears to be more sensitive to θd than the radiation-convection side. Furthermore, the given analytical solution is adequately verified against the proposed FEA method, having an error of less than 1.5%.

RESUMO

BACKGROUND: Drug utilisation studies are relevant for the analysis of prescription rationality and are pertinent in today's context of the increasing burden of antimicrobial resistance. Prescriptions for patients with diarrhoea or Acute Respiratory Infection (ARI) have been analysed in this study to understand the prescription pattern among various categories of prescribers in two tertiary care centers. METHODS: This cross-sectional study was conducted from August 2019 to December 2020 in the medicine and pediatrics outpatient departments of two government teaching hospitals in West Bengal, India. A total of 630 prescriptions were evaluated against WHO standards. Prescriptions were assessed by a 'Rational Use of Medicine Consensus committee' approach. RESULTS: The Fixed Dose Combination (FDC) was used in half of the patients (51%). Both the generic prescription (23.3%) and adherence to hospital formulary rates (36.5%) were low. The antibiotics prescription rate was high (57%), and it was higher for diarrhoea than ARI. Deviations from the standard treatment guidelines were found in 98.9% of prescriptions. Deviations were commonly found with prescriptions written by the junior doctors (99.6%). CONCLUSION: Irrational prescribing patterns prevail in tertiary care centers and indicate the necessity of awareness generation and capacity building among prescribers regarding AMR and its unseen consequences.

RESUMO

Soil salinity is a pressing issue for sustainable food security in coastal regions. However, the coupling of machine learning and remote sensing was seldom employed for soil salinity mapping in the coastal areas of Bangladesh. The research aims to estimate the soil salinity level in a southwestern coastal region of Bangladesh. Using the Landsat OLI images, 13 soil salinity indicators were calculated, and 241 samples of soil salinity data were collected from a secondary source. This study applied three distinct machine learning models (namely, random forest, bagging with random forest, and artificial neural network) to estimate soil salinity. The best model was subsequently used to categorize soil salinity zones into five distinct groups. According to the findings, the artificial neural network model has the highest area under the curve (0.921), indicating that it has the most potential to predict and detect soil salinity zones. The high soil salinity zone covers an area of 977.94 km2 or roughly 413.51% of the total study area. According to additional data, a moderate soil salinity zone (686.92 km2) covers 30.56% of Satkhira, while a low soil salinity zone (582.73 km2) covers 25.93% of the area. Since increased soil salinity adversely affects human health, agricultural production, etc., the study's findings will be an effective tool for policymakers in integrated coastal zone management in the southwestern coastal area of Bangladesh.

RESUMO

A bentazone-resistant mutant of Synechococcus elongatus PCC7942, called Mu2, tolerated elevated NaCl concentrations. As bentazone and bromoxynil exhibit similar mechanism of action, we investigated whether the mutant also toleratedbromoxynil and found it to be true. The line of investigation was then whether the acclimation strategy for the three stressors, bentazone, bromoxynil and NaCl was same or different. The cellular contents of malondialdehyde, hydrogen peroxide and superoxide increased in wild type strain following all the treatments suggesting their toxicities due to oxidative response. Notwithstanding, there were apparently different anti-oxidative measures pertaining to the herbicide and salinity stress. Glutathione contents and activities of superoxide dismutase, catalase-peroxidase, glutathione S-transferase and glutathione reductase decreased under NaCl, whereas bromoxynil affected only glutathione S-transferase reductase. Moreover, in-gel assays revealed that bromoxynil promoted appearance of isozymes of catalase-peroxidase, while NaCl induced such response only for superoxide dismutase. On the other hand, in Mu2, glutathione peroxidase-reductase and glutathione showed upward trend after bromoxynil exposure, whereas NaCl raised peroxidase and superoxide dismutase. Proteome comparison revealed peroxiredoxin Q to be highly expressed in wild type strain under bromoxynil, whereas NaCl favoured flavodoxin over-expression. Their amounts were already high in Mu2. We suggest that Mu2 acclimatized to bromoxynil in a manner similar to bentazone by upgrading peroxiredoxin Q and glutathione peroxidase-reductase. Conversely, for NaCl it devised another mechanism involving peroxidase and superoxide dismutase, and flavodoxin.

RESUMO

Background: Early identification and intervention of neonatal sepsis can improve the clinical outcome. Blood cultures remain the gold standard for diagnosis but are not easily available and require time. There is a need to identify and validate newer easily available cost-effective investigations, which would help in the diagnosis of neonatal sepsis. Aim: To test the hypothesis that whether platelet parameters, i.e., total platelet count (TPC), mean platelet volume (MPV), and the ratio of MPV/TPC can serve as diagnostic markers in neonatal sepsis. Methods: It is was a prospective study conducted in a tertiary care neonatal intensive care unit (NICU). The platelet parameters, i.e., TPC, MPV, and MPV/TPC of blood culture-positive septic neonates were compared with those of non-septic neonates admitted to the NICU. The diagnostic accuracy of the platelet indices was assessed by receiver operating characteristics (ROC) curves and sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Result: During the study period, 43 blood culture-positive sepsis neonates were compared with 54 cases of non-septic neonates. There was a significant difference in the mean of TPC, MPV, and MPV/TPC ratio between septic groups and non-septic groups. The sensitivity, specificity, PPV, NPV values of MPV (cut-off >9 fL) were 63.40%, 53.8%, 52.0%, and 65.11% respectively. The sensitivity, specificity, PPV, NPV of MPV/TPC ratio (>7.2) were 48.8%, 96.22%, 90.9%, and 70.42% respectively. The area under the curve (AUC) values for TPC, MPV, and MPV/TPC in the ROC analysis were 0.797, 0.641, and 0.809, respectively. Conclusion: Platelet indices MPV and MPV/TPC ratio can be useful in the early diagnosis of neonatal sepsis.

RESUMO

A Measles-Rubella (MR) vaccination campaign was launched in India in a phased manner in February 2017 to cover children aged 9 months to 15 years. As evidence on campaign vaccine delivery costs is limited, the delivery cost for MR campaign from a government provider perspective was estimated in four Indian states, namely, Assam, Gujarat, Himachal Pradesh, and Uttar Pradesh. Costs were calculated in top-down and bottom-up approaches using data collected from 84 sites at different administrative levels and immunization partners in the study states from August 2019 to March 2020. All costs were presented in 2019 US$ and Indian Rupee (INR). The financial cost per dose of the MR campaign including all partner support ranged from US$0.16 (INR 10.95) in Uttar Pradesh to US$0.34 (INR 24.13) in Gujarat. In Uttar Pradesh, the full economic cost per dose was US$0.87 (INR 61.39). The key financial cost drivers were incentives related to service delivery and supervision, the printing of reporting formats for record-keeping, social mobilization, and advocacy. The financial delivery cost per dose estimated was higher than the government pre-fixed budget per child for the MR campaign, probably indicating an insufficient budget. However, the study found underutilization of MR budget in two states and use of other sources of funding for the campaign indicating the need for proper utilization of the campaign budgets by the states. Unit cost information generated from this study will be useful for planning, cost projections, and economic analysis of future vaccination campaigns in India.
