Cost effectiveness of strategies for cervical cancer prevention in India

Is health technology assessment value for money? Estimating the return on investment of health technology assessment in India (HTAIn)

An increasing investment in health technology assessment (HTA) in low-income and middle-income countries has generated greater interest from policy-makers about the value and return on investment (ROI) of HTA. Few studies have, however, quantified the benefits of HTA in terms of its value to the health system. This evaluation aims to quantify the impact and ROI achieved by the HTA agency in India (HTAIn).A framework developed by the University of Glasgow was used to review three 'hta's commissioned by HTAIn between 2018 and 2020, taking into account the opportunity cost of investing in these processes. Costs included fixed costs for HTAIn and costs for undertaking each 'hta'. Attributable benefits are calculated by subtracting the counterfactual (benefits that might have been realised without an HTA) from realised benefits.HTAIn sits under the Department of Health Research, Ministry of Health and Family Welfare, Government of India. It was set up to facilitate the process of transparent and evidence-informed decision-making in healthcare in India.HTA helps decision-makers to understand the consequences of alternative courses of action and to select the options that produce the best outcomes at the lowest cost. Institutionalisation of HTA is seen as pivotal to supporting universal health coverage as a means of supporting a better allocation of finite resources, cost containment and the maximisation of health.Net health benefits are our measure of value. The ROI of HTAIn is calculated by aggregating attributable benefits and offsetting them against the costs of investment.Our findings show that investing in HTAIn yields a return of 9:1, with potential to increase to 71:1 with full implementation of HTA recommendations. Variability of ROI ranged from 5:1 to 40:1 between the different interventions and diseases.While HTAIn requires financial investment, it is an efficient use of resources. The potential for greater impact and the variability of the ROI between interventions underline the importance of planning for implementation and good topic selection in HTA.

A scoping review of evidence on routine cervical cancer screening in South Asia: investigating factors affecting adoption and implementation

NEED: Cervical cancer is a major global public health issue, particularly affecting low and middle-income countries, distinctly in the South Asian region. This geographical region lacks a well-organized routine cervical screening program. Consequently, this scoping review aimed to investigate the evidence on factors influencing the adoption and implementation of routine cervical cancer screening in South Asia.

METHODS

Adopting the "Arksey and O'Malley and Levac et al." methodology, databases such as PubMed, CINAHL, Web of Science, and Scopus were scrutinized in the pursuit of relevant studies. Subsequently, the collected data were synthesized by adopting the Consolidated Framework for Implementation Research (CFIR) model.

RESULTS

A total of 837 records were initially identified and screened for eligibility, including 55 studies. The successful adoption and implementation of cervical cancer screening in South Asia encounter numerous obstacles within the health system, including the absence of a comprehensive program protocol for screening, inadequate health infrastructure, and the presence of multiple sociocultural factors, such as social stigma, low levels of education, and concerns related to modesty.

CONCLUSION

To optimize adoption and implementation, it is imperative to construct a customized policy framework that incorporates a risk communication strategy tailored to the specific contexts of these nations. Drawing insights from the experiences of South Asian countries in executing cervical cancer screening programs can inform the formulation of policies for similar healthcare initiatives aimed at facilitating the expansion of HPV vaccination efforts.

Reproductive Health Among School Employees in Vijayapura, Karnataka

Background Cervical cancer typically progresses over 10-20 years, making it a preventable disease and underscoring the importance of screening. In low-resource settings, Papanicolaou (Pap) smears and visual inspection with acetic acid (VIA) serve as primary screening tools. This study was conducted as part of the noncommunicable disease camps organized by the government of Karnataka, India. Additionally, it aimed to evaluate the knowledge, attitudes, and practices related to contraception among women of reproductive age. Methods This cross-sectional study was conducted from June to August 2022 in primary health centers, community health centers, and government schools across all the Talukas of Vijayapura District, Karnataka, India. A total of 6,257 women participated in the study. The researchers interviewed all participants, obtained detailed medical histories, and performed pelvic examinations as part of the evaluation. Additionally, they conducted both VIA and Pap smears. Results A total of 6,257 women were sensitized for cervical cancer screening, of whom 5,114 registered, resulting in an acceptance rate of 81.73%. However, 1,143 participants (18.27%) refused screening, with the most common reason being unwillingness to undergo an examination. Only 3,316 women (53.91%) were aware of cervical cancer, and just 1,689 (27.1%) understood that it could be detected at an early stage. The VIA results indicated that 9.1% (n = 865) of the women tested positive. Among those screened, seven women (0.1%) were found to have a high-grade squamous intraepithelial lesion. Of these, four underwent colposcopy-guided biopsy, while three were lost to follow-up; all four biopsies were negative for malignancy. Additionally, two women presented with apparent cervical growths. Regarding contraceptive practices, 2,690 women (43.3%) expressed support for using contraception, with the permanent method of sterilization being the most preferred by 1,990 women (74.13%). Conclusions Screening with basic investigations such as Pap smears and VIA plays a crucial role in identifying premalignant and malignant lesions at their earliest stages, enabling timely treatment to reduce morbidity and mortality. Additionally, most women opt for permanent contraception once they have completed their families.

Strategies and implementation outcomes of HPV-based cervical screening studies to prevent cervical cancer in India: A systematic review

BACKGROUND

As Indian states consider HPV testing for cervical screening, there is a need to review evidence from prior studies to inform program design and evaluate implementation research gaps.

DESIGN

We conducted a systematic review of original articles in Medline, Embase, Global Health and Web of Science, published from 2000 to May 4, 2024. Articles describing use of HPV as a primary cervical screening test in India, in either community-based programs for the general population, or among women living with HIV, were included. We describe approaches to invitation, education, screening, and follow-up, and map determinants and outcomes to the RE-AIM and the Consolidated Framework for Implementation Research frameworks.

RESULTS

Of 71 included articles (51 unique studies), 19 reported on screening among women living with HIV, while 52 were community-based (general population of women). Self-collection was offered by 15 studies and was acceptable to most screened women. Community-based programs were mainly facility or outreach-based, with three studies offering only home-based self-collection, including one that integrated with cardiovascular risk screening. Studies from northeastern and tribal populations were scarce. Only one self-collection study used a screen and treat (at second visit) approach, but did not report follow-up, while none offered immediate treatment following a point-of-care test.

CONCLUSIONS

Community-based HPV testing, including self-collection, is feasible in India, with more research needed among underrepresented populations. Further implementation research is needed on integrating HPV screening with existing health systems, feasibility of HPV test and treat models and genotyping triage, to improve follow-up in low resource settings.

IAPSM's Position Paper on the Human Papilloma Virus (HPV) Vaccine for Adult Immunization in India

Cervical cancer ranks as the second most common cancer in women in India, primarily caused by persistent infection with the human papillomavirus (HPV). Given its long latent period, secondary prevention through screening and early detection is essential. However, fear and stigma associated with cancers and the costs involved in disease management are the prominent barriers to its uptake. HPV vaccination is one of the vital components of the World Health Organization's (WHO) Global Strategy to speed up the elimination of cervical cancer as a public health problem. In India, four prophylactic HPV vaccines are currently available. These vaccines are non-infective and highly immunogenic, safe, and effective when administered before HPV exposure. According to WHO recommendations, the primary target group for HPV vaccination consists of girls between the ages of 9 and 14 years. Further, studies have confirmed that both single-dose and two-dose schedules of the HPV vaccine offer comparable efficacy and protection. HPV vaccines are administered intramuscularly in the deltoid region, with 0.5 ml as the standard dose. These vaccines may cause local reactions, as well as mild systemic reactions, such as headache and myalgia, but they are transient. Implementing catch-up vaccination for adolescent girls aged between 9 and 14 years at the time of HPV vaccine introduction would be a cost-effective and sustainable strategy. This would serve as a crucial component of public health efforts to manage HPV infections and eliminate cervical cancer in India.

Current evidence and future direction on evaluating the anticancer effects of curcumin, gingerols, and shogaols in cervical cancer: A systematic review

Cervical cancer ranked fourth most common malignancy among women worldwide despite the establishment of vaccination programmes. This systematic review evaluates the anti-cancer properties of turmeric and ginger bioactive compounds, specifically curcumin, 6/10-gingerol, and 6/10-shogaol, and their combination in cervical cancer through in-vitro and in-vivo models. A comprehensive electronic search was performed using Science Direct, PubMed, and Scopus from inception until the second week of June 2024 for studies published in English. Only studies investigating the effects of curcumin, gingerol, shogaol, and/or their combination in human cervical cancer cell lines and/or rodent animal models implanted with cervical cancer xenografts were included. Altogether, 27 studies were included in this review. The evidence gathered indicated that curcumin, 6/10-gingerol and 6-shogaol exert their anticancer action through modulation of cell signalling pathways, including AMPK, WNT, PI3K/AKT, and NF-κB pathway, and mediators including Bax/Bcl2, TNF-α, EGFR, COX-2, caspases-3, -9, p53, and pRb. However, the synergistic effect of these bioactive compounds is not known due to lack of evidence. In conclusion, curcumin, 6/10-gingerols, and 6-shogaols hold promise as therapeutic agents for cervical cancer. Yet, further research is essential to understand their combined efficacy, emphasising the need for additional studies exploring the synergistic anticancer effects of these bioactive compounds. Additional factors to explore include long-term effects and susceptibility of chemoresistant cervical cancer cells towards curcumin, shogaols, and gingerols.

Do current economic evaluations fully capture vaccine value: a review of evidence from India

INTRODUCTION

Traditional economic evaluations typically focus on direct health effects and costs offset to the healthcare system. However, vaccines offer significant indirect benefits beyond direct health effects, such as herd immunity, reduced force of infection, reduction in antimicrobial resistance, and others. Failure to consider these benefits while evaluating vaccines may undervalue vaccines. Therefore, it is argued that the full value of vaccines should be estimated by incorporating these broader benefits.

AREAS COVERED

This review presents the broader value domains proposed in literature by various frameworks, and their definitions. The review of economic evidence of vaccine use in India to discuss to what extent these broader value domains have been considered in economic evaluations in India has been presented. We also discuss specific considerations that need to be taken care of while developing value frameworks or guidelines for the economic evaluation of vaccines.

EXPERT OPINION

To develop a comprehensive framework tailored to the country needs, prioritize relevant value domains and optimal methodologies based on the country's healthcare context, and data availability. These value domains must align with people's as well as decision-makers preferences to ensure economic assessments are relevant and actionable.

Screening for cervical and breast cancer among community health care workers (ASHAs) of Puri district, Odisha

BACKGROUND

Breast cancer and cervical cancer are the leading causes of cancer-related mortality in Indian women. As part of the Indian national guidelines for population-based cancer screening, village-level accredited social health activists (ASHAs) are the key mobilizers for encouraging women to undergo cervical and breast cancer screening. Assessing screening rates in these health workers themselves, can improve implementation of the national program by identifying some of the facilitators and barriers for screening.

METHODS

A cross-sectional study was conducted among ASHAs in Puri, Odisha, in eight primary health centers (PHCs) randomly selected from 10 blocks. Of all 291 ASHAs in these PHCs, 242 (83.2%) who consented, were given a self-administered questionnaire to assess screening and its associated factors.

RESULTS

The screening rates for cervical and breast screening in ASHA workers were 9.1% (95% CI: 5.4%-12.8%, 22/242) and 14.9% (95% CI: 10.3%-19.5%, 36/242), respectively. Having undergone screening themselves, was associated with referring others for screening (83.3% of those screened for breast cancer had referred others vs 37.4% of those never screened; 86.4% of those screened for cervical cancer had referred others vs 34.1% of those never screened).

CONCLUSIONS

ASHAs reported low rates of screening for breast and cervical cancer. History of screening significantly influenced the referral of others for screening. ASHAs need to be empowered with both educational exposure as well as motivation for health-promoting activities for themselves, in order to increase population-wide screening coverage.

Cost-effectiveness analysis of alternative screening strategies for the detection of cervical cancer among women in rural areas of Western Kenya

While the incidence of cervical cancer has dropped in high-income countries due to organized cytology-based screening programs, it remains the leading cause of cancer death among women in Eastern Africa. Therefore, the World Health Organization (WHO) now urges providers to transition from widely prevalent but low-performance visual inspection with acetic acid (VIA) screening to primary human papillomavirus (HPV) DNA testing. Due to high HPV prevalence, effective triage tests are needed to identify those lesions likely to progress and so avoid over-treatment. To identify the optimal cost-effective strategy, we compared the VIA screen-and-treat approach to primary HPV DNA testing with p16/Ki67 dual-stain cytology or VIA as triage. We used a Markov model to calculate the budget impact of each strategy with incremental quality-adjusted life years and incremental cost-effectiveness ratios (ICER) as the main outcome. Deterministic cost-effectiveness analyses show that the screen-and-treat approach is highly cost-effective (ICER 2469 Int$), while screen, triage, and treat with dual staining is the most effective with favorable ICER than triage with VIA (ICER 9943 Int$ compared with 13,177 Int$). One-way sensitivity analyses show that the results are most sensitive to discounting, VIA performance, and test prices. In the probabilistic sensitivity analyses, the triage option using dual stain is the optimal choice above a willingness to pay threshold of 7115 Int$ being cost-effective as per WHO standards. The result of our analysis favors the use of dual staining over VIA as triage in HPV-positive women and portends future opportunities and necessary research to improve the coverage and acceptability of cervical cancer screening programs.

Economic Evaluation of Cervical Cancer Screening by HPV DNA, VIA, and Pap smear Methods in Indonesia

BACKGROUND

Cervical cancer occurs 80% in developing country including Indonesia and take place in the first rank of incidence rate and third rank in mortality rate in Asian Pacific. Natural history of cervical cancer gives a potential to get accurate screening method. Cervical cancer screening m in Indonesia use VIA and Pap smear method for women in age range 30 to 50 years old. Recently, HPV DNA test has been recommended in international and national policy as primary screening method for cervical cancer. This research aims to  asses cost-effectiveness and economic implications of specific cervical cancer screening modalities.

METHODS

Cost-effectiveness analysis was conducted from societal perspective. Cost data was collected from four hospitals in Indonesia. Direct medical costs were derived from discussions with an expert panel and hospital billing data, aligning with current practice guidelines. Direct and indirect non-medical costs were estimated from patient interviews. Effectiveness data for the screening methods were extracted from a systematic review of existing literature. Markov model design was used for cost-effectiveness analysis. Budget impact analysis used healthcare perspective method from its billing for cervical cancer patients.

RESULTS

Cervical cancer screening costs are calculated using direct medical, non-medical, and indirect expenses. Regarding to cost-effective analysis by incremental cost-effective ratio (ICER), pap smear for every 3 and 5 years is more cost-effective than VIA. HPV DNA also has the potential to be cost-effective. The budget impact analysis investigates scenarios, with a focus on negotiation-based cost reductions for HPV DNA testing. Controlling HPV DNA tariffs at USD 8.76 proves cost-effective.

CONCLUSION

In conclusion, pap smear is the most cost-effective modality, while HPV DNA has the potential to be cost-effective by reducing the unit cost. Despite favorable outcomes, challenges in implementation suggest a phased approach for resource equalization before full deployment.

Cost-utility analysis of primary HPV testing through home-based self-sampling in comparison to visual inspection using acetic acid for cervical cancer screening in East district, Sikkim, India, 2023

INTRODUCTION

Primary Human Papilloma Virus (HPV) testing offers higher sensitivity and specificity over Visual Inspection using Acetic acid (VIA) in cervical cancer screening. Self-sampling is a promising strategy to boost participation and reduce disparities. However, concerns about the initial costs hinder HPV testing adoption in low and middle-income countries. This study assesses the cost-utility of home-based HPV self-sampling versus VIA for cervical cancer screening in India.

METHODS

A cross-sectional study was conducted in East district, Sikkim, India, comparing the costs and utility outcomes of population-based cervical cancer screening through VIA and primary HPV screening through self-sampling. Cost-related data were collected from April 2021 to March 2022 using the bottom-up micro-costing method, while utility measures were collected prospectively using the EuroQoL-5D-5L questionnaire. The utility values were converted into quality-adjusted life days (QALDs) for an 8-day period. The willingness to pay threshold (WTP) was based on per capita GDP for 2022. If the calculated Incremental Cost-Effectiveness Ratio (ICER) value is lower than the WTP threshold, it signifies that the intervention is cost-effective.

RESULTS

The study included 95 women in each group of cervical cancer screening with VIA & HPV self-sampling. For eight days, the QALD was found to be 7.977 for the VIA group and 8.0 for the HPV group. The unit cost per woman screened by VIA and HPV self-testing was ₹1,597 (US$ 19.2) and ₹1,271(US$ 15.3), respectively. The ICER was ₹-14,459 (US$ -173.6), which was much below the WTP threshold for eight QALDs, i.e. ₹ 4,193 (US$ 50.4).

CONCLUSION

The findings support HPV self-sampling as a cost-effective alternative to VIA. This informs policymakers and healthcare providers for better resource allocation in cervical cancer screening in Sikkim.

Randomized experimental population-based study to evaluate the acceptance and completion of and preferences for cervical cancer screening

Cervical cancer has high incidence and mortality rates, especially in less-developed countries. Prevention methods are well established, but there are still barriers preventing some Brazilian women from undergoing a Pap sample. The objective of the study was to evaluate the acceptance, preferences and completion of four screening methods. This has an experimental design (community trial). A total of 164 participants who had never had a Pap sample or had not had one for more than three years were included. The city's urban area was stratified by census tracts and divided according to income and education levels. Women belonging to the lower-income strata were considered in the study. Random blocks were numbered into five intervention groups (Group 1- Pap sample at the hospital; Group 2- Pap sample in the mobile unit; Group 3- urine self-collection; Group 4- vaginal self-collection; Group 5- woman's choice). Only 164 women met all of the eligibility criteria (15.3%). Most of them accepted the assigned method (92%), but only 84% of the women completed the collection step. The acceptance rates were as follows: Group 1 (100%), Group 2 (64.5%), Group 3 (100%) and Group 4 (91.4%). In Group 5, the women's preferences were distributed as follows: examination performed at the hospital, 13 women (33.3%); examination performed at the mobile unit, 11 women (28.2%); urine self-collection, 11 women (28.2%); and vaginal self-collection, 4 women (10.3%). This study suggests that methods that allow cervical sampling collected near the women's domicile might improve the acceptance and completion of preventive tests. This finding is relevant for the development of new cervical cancer screening strategies.

Cervical cancer screening by cytology and the burden of epithelial abnormalities in low resource settings: a tertiary-center 42-year study

BACKGROUND

Cytological screening remains a high-impact practice, particularly in low-resource settings, for preventing cervical cancer. The examination of screening practices over time and the prevalence of epithelial abnormalities have not been investigated in longitudinal studies in one of the largest countries in the Middle East and Africa.

METHODS

Routine healthcare data, between March 1981 and December 2022, were extracted from the database of the Early Cancer Detection Unit in a tertiary referral university hospital in the Greater Cairo Region, Egypt. Cervical smears were obtained using a standardized technique and sent to the cytopathology laboratory for conventional cytology examination by expert pathologists. The anonymous data were analyzed to determine the temporal trend of the number of women screened each year and the prevalence of epithelial abnormalities.

RESULTS

Data included the results of satisfactory smears from 95120 women. The mean age (SD) of the women at the time of screening was 38.5 (10.5). None of the included women received an HPV vaccine. Abnormal epithelial cells were reported in 5174 women (5.44%). Of these epithelial abnormalities, the majority were low-grade squamous intraepithelial lesions in 4144 women (4.36%). Other abnormalities included atypical squamous cells in 378 women (0.40%), high-grade squamous intraepithelial lesions in 226 women (0.24%), atypical glandular cells not otherwise specified in 184 women (0.19%), adenocarcinoma in 165 women (0.17%), squamous cell carcinoma in 70 women (0.07%), and atypical glandular cells favoring neoplasms in 7 women (0.01%). Women who were at an early age at first intercourse, those who opted for routine cervical cytology screening, and those who were older at screening were more likely to have epithelial abnormalities. The yearly number of screened women was positively associated with the detection of low-grade squamous intraepithelial lesions (correlation coefficient [95% CI] = 0.84 [0.72, 0.91]) and negatively associated with the detection of squamous cell carcinoma (correlation coefficient [95% CI] = -0.55 [-0.73, -0.29]).

CONCLUSIONS

The small number of annually screened Egyptian women and the temporal trend in epithelial abnormalities critically demonstrate the need for establishing and scaling up a structured population-based program to achieve the goal of eliminating cervical cancer.

HPVsim: An agent-based model of HPV transmission and cervical disease

In 2020, the WHO launched its first global strategy to accelerate the elimination of cervical cancer, outlining an ambitious set of targets for countries to achieve over the next decade. At the same time, new tools, technologies, and strategies are in the pipeline that may improve screening performance, expand the reach of prophylactic vaccines, and prevent the acquisition, persistence and progression of oncogenic HPV. Detailed mechanistic modelling can help identify the combinations of current and future strategies to combat cervical cancer. Open-source modelling tools are needed to shift the capacity for such evaluations in-country. Here, we introduce the Human papillomavirus simulator (HPVsim), a new open-source software package for creating flexible agent-based models parameterised with country-specific vital dynamics, structured sexual networks, and co-transmitting HPV genotypes. HPVsim includes a novel methodology for modelling cervical disease progression, designed to be readily adaptable to new forms of screening. The software itself is implemented in Python, has built-in tools for simulating commonly-used interventions, includes a comprehensive set of tests and documentation, and runs quickly (seconds to minutes) on a laptop. Performance is greatly enhanced by HPVsim's multiscale modelling functionality. HPVsim is open source under the MIT License and available via both the Python Package Index (via pip install) and GitHub (hpvsim.org).

Lightweight Low-Rank Adaptation Vision Transformer Framework for Cervical Cancer Detection and Cervix Type Classification

Cervical cancer is a major health concern worldwide, highlighting the urgent need for better early detection methods to improve outcomes for patients. In this study, we present a novel digital pathology classification approach that combines Low-Rank Adaptation (LoRA) with the Vision Transformer (ViT) model. This method is aimed at making cervix type classification more efficient through a deep learning classifier that does not require as much data. The key innovation is the use of LoRA, which allows for the effective training of the model with smaller datasets, making the most of the ability of ViT to represent visual information. This approach performs better than traditional Convolutional Neural Network (CNN) models, including Residual Networks (ResNets), especially when it comes to performance and the ability to generalize in situations where data are limited. Through thorough experiments and analysis on various dataset sizes, we found that our more streamlined classifier is highly accurate in spotting various cervical anomalies across several cases. This work advances the development of sophisticated computer-aided diagnostic systems, facilitating more rapid and accurate detection of cervical cancer, thereby significantly enhancing patient care outcomes.

Cost-effectiveness of single-visit cervical cancer screening in KwaZulu-Natal, South Africa: a model-based analysis accounting for the HIV epidemic

Introduction

Women living with human immunodeficiency virus (WLHIV) face elevated risks of human papillomavirus (HPV) acquisition and cervical cancer (CC). Coverage of CC screening and treatment remains low in low-and-middle-income settings, reflecting resource challenges and loss to follow-up with current strategies. We estimated the health and economic impact of alternative scalable CC screening strategies in KwaZulu-Natal, South Africa, a region with high burden of CC and HIV.

Methods

We parameterized a dynamic compartmental model of HPV and HIV transmission and CC natural history to KwaZulu-Natal. Over 100 years, we simulated the status quo of a multi-visit screening and treatment strategy with cytology and colposcopy triage (South African standard of care) and six single-visit comparator scenarios with varying: 1) screening strategy (HPV DNA testing alone, with genotyping, or with automated visual evaluation triage, a new high-performance technology), 2) screening frequency (once-per-lifetime for all women, or repeated every 5 years for WLHIV and twice for women without HIV), and 3) loss to follow-up for treatment. Using the Ministry of Health perspective, we estimated costs associated with HPV vaccination, screening, and pre-cancer, CC, and HIV treatment. We quantified CC cases, deaths, and disability-adjusted life-years (DALYs) averted for each scenario. We discounted costs (2022 US dollars) and outcomes at 3% annually and calculated incremental cost-effectiveness ratios (ICERs).

Results

We projected 69,294 new CC cases and 43,950 CC-related deaths in the status quo scenario. HPV DNA testing achieved the greatest improvement in health outcomes, averting 9.4% of cases and 9.0% of deaths with one-time screening and 37.1% and 35.1%, respectively, with repeat screening. Compared to the cost of the status quo ($12.79 billion), repeat screening using HPV DNA genotyping had the greatest increase in costs. Repeat screening with HPV DNA testing was the most effective strategy below the willingness to pay threshold (ICER: $3,194/DALY averted). One-time screening with HPV DNA testing was also an efficient strategy (ICER: $1,398/DALY averted).

Conclusions

Repeat single-visit screening with HPV DNA testing was the optimal strategy simulated. Single-visit strategies with increased frequency for WLHIV may be cost-effective in KwaZulu-Natal and similar settings with high HIV and HPV prevalence.

Protocol for the formative phase of a trial (SHE-CAN) to test co-designed implementation strategies for HPV-based cervical screening among vulnerable women in two diverse settings in India

BACKGROUND

In view of the WHO's call for the elimination of cervical cancer as a public health problem, and current low screening coverage, Indian policy makers need evidence on how to effectively implement cervical screening programmes, ensuring equity in access. Our study will follow the INSPIRE implementation framework to co-design and test HPV-based screening approaches in two states of India with different health system organisation, based on understanding the status of screening as currently implemented, readiness and challenges to transition to HPV-based screening, and preferences of key stakeholders. Here, we describe our protocol for the formative phase of the study (SHE-CAN).

METHODS

The study population includes women from vulnerable populations, defined as residents of tribal areas, rural villages, and urban slums, in the states of Mizoram and Tamil Nadu. The baseline assessment will use mixed methods research, with desktop reviews, qualitative studies, and surveys. A capacity assessment survey of screening and treatment facilities will be done, followed by interviews with healthcare providers, programme managers, and community health workers. Interviews will be conducted with previously screened women and focus group discussions with under and never-screened women and community members. Stakeholder workshops will be held in each state to co-design the approaches to delivering HPV-based screening among 30-49-year-old women.

DISCUSSION

The quality and outcomes of existing screening services, readiness to transition to HPV-based screening, challenges in providing and participating in the cervical cancer care continuum, and acceptability of screening and treatment approaches will be examined. The knowledge gained about the current system, as well as recognition of actions to be taken, will inform a stakeholder workshop to co-design and evaluate implementation approaches for HPV-based screening through a cluster randomised implementation trial.

Health-related quality of life among Indian population: The EQ-5D population norms for India

Background

The EuroQol 5 dimensions (EQ-5D) is the most used generic health-related quality of life (HRQoL) instrument for measuring population health and health outcomes. Since there are no EuroQol 5 dimensions 5 levels (EQ-5D-5L) population norms available for India, this study developed the Indian population norms for the EQ-5D-5L. The potential influencing factors of HRQoL of the Indian population have been identified.

Methods

The data was collected alongside the Indian EQ-5D-5L valuation study (Development of an EQ-5D Value Set for India Using an Extended Design: DEVINE Study). A cross-sectional survey of 3548 adult respondents was conducted across five states of India, in which respondents were asked to report their own health states using the EQ-5D-5L descriptive system and the EuroQol Visual Analog Scale (EQ VAS). The utility score was calculated using the EQ-5D-5L value set based on the preferences of the Indian population. Norm scores were generated for age, sex, and other important socio-demographic variables. The proportion of patients reporting problems in different dimensions of EQ-5D-5L was assessed. The impact of socio-economic determinants on health-related quality of life was evaluated using multiple linear regression.

Results

The mean EQ VAS score of the Indian population is 75.18 (95% confidence interval (CI) = 74.50-75.90), whereas mean utility score is 0.848 (95% CI = 0.840-0.857). The EQ VAS scores, and utility scores decreased with age. Males reported higher EQ VAS values than females. The highest mean utility score was observed for males of <20 years (0.936), whereas the lowest mean score was observed for females of >70 years (0.488). The mean VAS score ranged between 85.24 for females of <20 years and 50.67 for females of >70 years. Highest problems were reported in the dimension of "pain / discomfort", closely followed by "anxiety / depression". Age, educational qualification, marital status, substance abuse, presence of ailments, state / region of residence, number of dependent members in the household, and time spent on mobile are the significant determinants of HRQoL of Indian population.

Conclusions

These population norms will be used as reference values for comparative purposes in future Indian studies. Economic evaluations can use these average age-specific HRQoL population norms to value the health-state of not having the specific disease under investigation.

An ultrasensitive electrochemical DNA biosensor for monitoring Human papillomavirus-16 (HPV-16) using graphene oxide/Ag/Au nano-biohybrids

A DNA-based electrochemical biosensor has been developed herein for the detection of Human papillomavirus-16 (HPV-16). HPV-16 is a double-stranded, non-enveloped, epitheliotropic DNA virus which responsible for cervical cancer. In this proposed biosensor, an indium tin oxide (ITO) coated glass electrode was modified for sensing HPV-16 using graphene oxide and silver coated gold nanoparticles. Subsequently, HPV-16 specific DNA probes were immobilized on a modified ITO surface. The synthesized nanocomposites were characterized by FE-SEM and UV-VIS spectroscopy techniques. Electrochemical characterization was performed by using cyclic voltammetry and electrochemical Impedance Spectroscopy methods. The hybridization between the probe and target DNA was analyzed by a reduction in current, mediated by methylene blue. The biosensor showed a qualitative inequity between the probe and target HPV-16 DNA. The developed biosensor showed high sensitivity as 0.54 mA/aM for the detection of HPV-16. In a linear range of 100 aM to 1 μM with 100 aM LOD, the proposed biosensor exhibited excellent performance with the rapid diagnosis. Thus, the results indicate that the developed HPV DNA biosensor shows good consistency with the present approaches and opens new opportunities for developing point-of-care devices. The diagnosis of HPV-16 infection in its early stage may also be possible with this detection system.

Audio-Visual Training Improves Awareness and Willingness of Cervical Cancer Screening among Healthy Indian Women: Findings from a Survey

Priya GaneshkumarObjectives  We evaluated the impact of a standardized, simple audio-visual (AV) training video developed in regional languages on cervical cancer awareness among apparently healthy women and their willingness to undergo regular cervical cancer screening. Materials and Methods  This cross-sectional noninterventional multicentric survey was conducted in 69 centers across 14 states in India and one center in UAE among women aged between 18 and 88 years attending clinics for a variety of indications. Using a short questionnaire, cervical cancer awareness and willingness to undergo cervical cancer screening were assessed before and after the AV training. Statistical Analysis  In addition to descriptive analysis, improvement in awareness after the AV training was assessed using McNemar's test, and comparison of responses between subgroups was performed using Pearson chi-squared test. Results  The survey was completed by 3,188 apparently healthy women (mean age: 36.8 ± 11.3 years). Before AV training, correct answers were given to only 4/6 questions by majority of the participants; most participants were unaware about the main cause of cervical cancer (1,637/3,188, 51.4%), availability of cervical cancer screening tests (1,601/3,188, 50.2%), and cervical cancer vaccines (1,742/3,188, 54.6%). Only 576 women (18.1%) had undergone cervical cancer screening in the past. After the AV training, the proportion of women correctly responding to all six questions improved significantly (p < 0.05), and 84.4% (2691/3188) women showed willingness to undergo periodic cervical cancer screening. Compared to unmarried and professional women, although married women and home-makers had lower awareness scores, the latter subgroups had more often undergone previous cervical cancer screening. Conclusion  It is possible to improve cervical cancer awareness among healthy women, and to enhance their willingness to undergo regular cervical cancer screening tests using a simple, six minute-long, standardized AV training material.

Phone-Based Breasts Self-Examination as an Intervention in Breast Cancer Control During the COVID-19 Pandemic

Importance

Exploring methods to mitigate the effect of COVID-19 pandemic on routine cancer screening activities among women.

Objective

To investigate the effectiveness of telephone-based outreach as a substitute for physical screening for breast among screened women, during COVID-19 lockdown.

Design/Setting/Subjects

Asymptomatic women aged 30–59 years were screened for breast and cervix cancers in the Chennai region, between January 2017 and March 2020 and are due for screening follow-up. A database from the population-based cancer screening program organized by the Cancer Institute during the above period was used for the study. Outcome data were obtained through the period from October 2020 to March 2021.

Intervention

Phone-based breast self-examination awareness, inquiry about breast cancer symptoms, and guiding clinical management.

Outcome Measure

Compliance to BSE protocol after 8–16 weeks, presence of significant symptoms, and incidence of early breast cancer.

Results

Among 12,242 screened women, 6716 (56.8%) responded to a phone-based BSE intervention and 53 women had breast-related symptoms. Thirty-two (60.4%) women reported for further evaluation, and five invasive breast cancers were identified.

Conclusion and Relevance

In a low-resource setting where there are no existent screening programs, simple interventions like teaching breast self-examination of women through tele-counseling can result in early detection of breast cancers.

A systematic review of economic evaluations of cervical cancer screening methods

OBJECTIVE

The aims of this systematic review were to (1) identify primary- and model-based economic evaluations of cervical cancer screening methods and to (2) provide a contextual summary of valuation outcomes associated with three types of cervical cancer screening tests: visual inspection with acetic acid, human papillomavirus deoxyribonucleic acid, and Papanicolaou smear.

INTRODUCTION

Cervical cancer screening is an important public health priority with the potential to improve the detection of precancerous lesions in high-risk females for early intervention and disease prevention. Test performance and cost-effectiveness differ based on the specific screening method used across different platforms. There is a need to appraise existing economic evaluations of cervical cancer screening methods.

METHODS

This review considered primary-based and model-based full economic evaluations of cervical cancer screening methods. The evaluation methods of interest included cost-effectiveness analysis, cost-utility analysis, cost-minimization analysis, cost-benefit analysis, and cost-consequence analysis. We searched Scopus, PubMed, National Health Economic Evaluation Database (NH EED), Cochrane, and the Health Economic Evaluation Database for full economic evaluations of cancer screening methods. No formal date restrictions were applied. Model-based and primary-based full economic evaluations were included. A critical appraisal of included studies was performed by the main investigator, while a second independent reviewer assessed critical appraisal findings for any inconsistencies. Data were extracted using a standardised data extraction tool for economic evaluations. The ultimate outcomes of costs, effectiveness, benefits, and utilities of cervical cancer screening modalities were extracted from included studies, analysed, and summarised.

RESULTS

From a total of 671 screened studies, 44 studies met the study inclusion criteria. Forty-three studies were cost-effectiveness analyses, one study reported both cost-utility and cost-effectiveness outcomes, and another study reported cost utilities of cervical cancer screening methods only. Human papillomavirus (HPV) DNA testing was reported as a dominant stand-alone screening test by 14 studies, while five studies reported visual inspection with acetic acid (VIA) as a dominant stand-alone screening test. Primary HPV screening strategies were dominant in 21 studies, while three studies reported cytology-based screening strategies as the dominant screening method.

CONCLUSIONS

Existing evidence indicates that HPV-based and VIA testing strategies are cost-effective, but this is dependent on setting. Our review suggests the limited cost-effectiveness of cytology-based testing, which may be due in part to the need for specific infrastructures and human resources.

A Technical Comparison of Human Papillomavirus Genotyping Assays from a Population-Based Cervical Cancer Screening in South Central Ethiopia

Purpose

High-risk Human Papillomavirus (HPV) is the most important cause of cervical cancer. The highest burden of disease is seen in Low- and Low-Middle-Income Countries (LMIC). Several new HPV screening assays have been developed for high-risk HPV (hr-HPV) testing. We compared the performance and adequacy of three HPV genotyping assays on samples from a population of rural women in south-central Ethiopia.

Patients and Methods

One hundred and ten cervical swabs from rural women screened for HPV were assayed. HPV DNA was tested using MPG-Luminex Assay, Anyplex II HPV HR Detection, and EUROArray HPV. MPG-Luminex Assay was used as a reference method to compute the sensitivity and specificity of the two commercial assays in detecting hr-HPV infections.

Results

Of the 110 samples, MPG-Luminex Assay found 18.2% positive for the 14 hr-HPV and 7.3% for the probable hr-HPV genotypes. Anyplex™ II HPV HR Detection assay and EUROArray HPV Assay identified 21.82% and 12.7% samples, respectively, for the 14 hr-HPVs and both 7.3% for the probable hr-HPV genotypes (κ=0.734). Among the 14 hr-HPV genotypes, the genotype-specific agreement of the three HPV genotyping assays was moderate or better for HPV16, 31, 35, 39, 52, 56, 66 and 68. The aggregated sensitivity in detecting the 14 hr-HPV infections of Anyplex™ II HPV HR Detection and EUROArray HPV assays was high, 100% and 70%, respectively. The specificities of Anyplex™ II HPV HR Detection and EUROArray HPV were 95.6% and 100%, respectively.

Conclusion

The three evaluated assays showed similar analytical performance in the detection of hr-HPV infections and moderate or better concordance in HPV genotyping. This study is part of the ongoing cluster-randomized trial that has been registered in clinicaltrials.gov (NCT03281135) on September 13, 2017.

Development of an EQ-5D Value Set for India Using an Extended Design (DEVINE) Study: The Indian 5-Level Version EQ-5D Value Set

OBJECTIVES

This study aimed to develop the Indian 5-level version EQ-5D (EQ-5D-5L) value set, which is a key input in health technology assessment for resource allocation in healthcare.

METHODS

A cross-sectional survey using the EuroQol Group's Valuation Technology was undertaken in a representative sample of 3548 adult respondents, selected from 5 different states of India using a multistage stratified random sampling technique. The participants were interviewed using a computer-assisted personal interviewing technique. This study adopted a novel extended EuroQol Group's Valuation Technology design that included 18 blocks of 10 composite time trade-off (c-TTO) tasks, comprising 150 unique health states, and 36 blocks of 7 discrete choice experiment (DCE) tasks, comprising 252 DCE pairs. Different models were explored for their predictive performance. Hybrid modeling approach using both c-TTO and DCE data was used to estimate the value set.

RESULTS

A total of 2409 interviews were included in the analysis. The hybrid heteroscedastic model with censoring at -1 combining c-TTO and DCE data yielded the most consistent results and was used for the generation of the value set. The predicted values for all 3125 health states ranged from -0.923 to 1. The preference values were most affected by the pain/discomfort dimension.

CONCLUSIONS

This is the largest EQ-5D-5L valuation study conducted so far in the world. The Indian EQ-5D-5L value set will promote the effective conduct of health technology assessment studies in India, thereby generating credible evidence for efficient resource use in healthcare.

Cost Effectiveness of Bevacizumab Plus Chemotherapy for the Treatment of Advanced and Metastatic Cervical Cancer in India-A Model-Based Economic Analysis

PURPOSE

Patients with advanced and metastatic cervical cancer have a poor prognosis with a 1-year survival rate of 10%-15%. Recently, an antiangiogenic humanized monoclonal antibody bevacizumab has shown to improve the survival of these patients. This study was designed to assess the cost effectiveness of incorporating bevacizumab with standard chemotherapy for the treatment of patients with advanced and metastatic cervical cancer in India.

METHODS

Using a disaggregated societal perspective and lifetime horizon, a Markov model was developed for estimating the costs and health outcomes in a hypothetical cohort of 1,000 patients with advanced and metastatic cervical cancer treated with either standard chemotherapy alone or in combination with bevacizumab. Effectiveness data for each of the treatment regimen were assessed using estimates from Gynecologic Oncology Group 240 trial. Data on disease-specific mortality in metastatic cervical cancer, health system cost, and out-of-pocket expenditure were derived from Indian literature. Multivariable probabilistic sensitivity analysis was undertaken to account for parameter uncertainty.

RESULTS

Over the lifetime of one patient with advanced and metastatic cervical cancer, bevacizumab along with standard chemotherapy results in a gain of 0.275 (0.052-0.469) life-years (LY) and 0.129 (0.032-0.218) quality-adjusted life-years (QALY), at an additional cost of $3,816 US dollars (USD; 2,513-5,571) compared with standard chemotherapy alone. This resulted in an incremental cost of $19,080 USD (7,230-52,434) per LY gained and $34,744 USD (15,782-94,914) per QALY gained with the use of bevacizumab plus standard chemotherapy.

CONCLUSION

Addition of bevacizumab to the standard chemotherapy is not cost effective for the treatment of advanced and metastatic cervical cancer in India at a threshold of 1-time per-capita gross domestic product.

Secular trends in incidence and mortality of cervical cancer in India and its states, 1990-2019: data from the Global Burden of Disease 2019 Study

BACKGROUND

Cervical cancer is the fourth most common cancer that occurs to women worldwide. This study aims to assess trends in incidence and mortality of cervical cancer in India and its states over past three decades for tracking the progress of strategies for the prevention and control of cervical cancer.

METHODS

Data on cervical cancer incidence and mortality from 1990 to 2019 for India and its states were extracted from Global Burden of Disease study and were utilized for the analysis. Spatial and rank map has been used to see the changes in incidence and mortality of cervical cancer in different Indian states. Further, joinpoint regression analysis is applied to determine the magnitude of the time trends in the age standardized incidence and mortality rates of cervical cancer. We obtained the average annual percent change (AAPC) and corresponding 95% confidence intervals (CI) for each state.

RESULTS

Overall, from 1990 to 2019 Jharkhand (Incidence: -50.22%; Mortality: -56.16%) recorded the highest percentage decrement in cervical cancer incidence and mortality followed by the Himachal Pradesh (Incidence: -48.34%; Mortality: -53.37%). Tamilnadu (1^st rank), Jammu & Kashmir and Ladakh (32^nd rank) maintained the same rank over the period of three decade for age standardized cervical cancer incidence and mortality. The regression model showed a significant declining trend in India between 1990 and 2019 for age standardized incidence rate (AAPC: -0.82; 95%CI: -1.39 to -0.25; p < 0.05) with highest decline in the period 1998-2005 (AAPC: -3.22; 95%CI: -3.83 to -2.59; p < 0.05). Similarly, a significant declining trend was observed in the age standardized mortality rate of India between 1990 and 2019(AAPC: -1.35; 95%CI: -1.96 to -0.75; p < 0.05) with highest decline in the period 1998-2005 (AAPC: -3.52; 95%CI: -4.17 to -2.86; p < 0.05).

CONCLUSION

Though the incidence and mortality of cervical cancer declined over past three decades but it is still a major public health problem in India. Information, education and communication activities for girls, boys, parents and community for the prevention and control of cervical cancer should be provided throughout the country.

No Family Should Suffer From Cervical Cancer Twice-The Palliative Care Role in HPV Prevention

BACKGROUND

Cervical cancer, caused by human papillomavirus infection, is the source of significant personal and societal burden, and robs more than one hundred thousand Indian women and their families of the chances of a healthy and productive life each year. As outlined by the World Health Organization, the three-pronged approach of screening, vaccination, and reduction in mortality by early treatment presents the possibility of the elimination of cervical cancer as a public health problem in the next decade.¹ Unfortunately, these approaches are all associated with significant barriers in India.

OBJECTIVES

Given that the main mandate of palliative care practitioners to prevent and relieve suffering, here we make the case for these practitioners to offer education around vaccination and screening to female relatives of women encountered with cervical cancer.

CONCLUSION

Offering prevention strategies for human papillomavirus aligns with the idea of preventing suffering and is within the scope of palliative care clinicians.

The state of cost-utility analysis in India: A systematic review

Aims:

Cost-utility studies are crucial tools that help policy-makers promote appropriate resource allocation. The objective of this study was to evaluate the extent and quality of cost-utility analysis (CUA) in India through a systematic literature review.

Methods:

Comprehensive database search was conducted to identify the relevant literature published from November 2009 to November 2019. Gray literature and hand searches were also performed. Two researchers independently reviewed and assessed study quality using Consolidated Health Economic Evaluation Reporting Standards checklist.

Results:

Thirty-five studies were included in the final review. Thirteen studies used Markov model, five used decision tree model, four used a combination of decision tree and Markov model and one each used microsimulation and dynamic compartmental model. The primary therapeutic areas targeted in CUA were infectious diseases (n = 12), ophthalmology (n = 5), and endocrine disorders (n = 4). Five studies were carried out in Tamil Nadu, four in Goa, three in Punjab, two each in Delhi, Maharashtra, and Uttar Pradesh, and one each in West Bengal and Karnataka. Twenty-three, eight, and four studies were found to be of excellent, very good, and good quality, respectively. The average quality score of the studies was 19.21 out of 24.

Conclusions:

This systematic literature review identified the published CUA studies in India. The overall quality of the included studies was good; however, features such as subgroup analyses and explicit study perspective were missing in several evaluations.

Development of National Cancer Database for Cost and Quality of Life (CaDCQoL) in India: a protocol

INTRODUCTION

The rising economic burden of cancer on healthcare system and patients in India has led to the increased demand for evidence in order to inform policy decisions such as drug price regulation, setting reimbursement package rates under publicly financed health insurance schemes and prioritising available resources to maximise value of investments in health. Economic evaluations are an integral component of this important evidence. Lack of existing evidence on healthcare costs and health-related quality of life (HRQOL) makes conducting economic evaluations a very challenging task. Therefore, it is imperative to develop a national database for health expenditure and HRQOL for cancer.

METHODS AND ANALYSIS

The present study proposes to develop a National Cancer Database for Cost and Quality of Life (CaDCQoL) in India. The healthcare costs will be estimated using a patient perspective. A cross-sectional study will be conducted to assess the direct out-of-pocket expenditure (OOPE), indirect cost and HRQOL among cancer patients who will be recruited at seven leading cancer centres from six states in India. Mean OOPE and HRQOL scores will be estimated by cancer site, stage of disease and type of treatment. Economic impact of cancer care on household financial risk protection will be assessed by estimating prevalence of catastrophic health expenditures and impoverishment. The national database would serve as a unique open access data repository to derive estimates of cancer-related OOPE and HRQOL. These estimates would be useful in conducting future cost-effectiveness analyses of management strategies for value-based cancer care.

ETHICS AND DISSEMINATION

Approval was granted by Institutional Ethics Committee vide letter no. PGI/IEC-03/2020-1565 of Post Graduate Institute of Medical Education and Research, Chandigarh, India. The study results will be published in peer-reviewed journals and presented to the policymakers at national level.

Cost of scaling-up comprehensive primary health care in India: Implications for universal health coverage

India has announced the ambitious program to transform the current primary healthcare facilities to health and wellness centres (HWCs) for provision of comprehensive primary health care (CPHC). We undertook this study to assess the cost of this scale-up to inform decisions on budgetary allocation, as well as to set the norms for capitation-based payments. The scale-up cost was assessed from both a financial and an economic perspective. Primary data on resources used to provide services in 93 sub-health centres (SHCs) and 38 primary health care centres (PHCs) were obtained from the National Health System Cost Database. The cost of additional infrastructure and human resources was assessed against the normative guidelines of Indian Public Health Standards and the HWC. The cost of other inputs (drugs, consumables, etc.) was determined by undertaking the need estimation based on disease burden or programme guidelines, standard treatment guidelines and extent and pattern of care utilization from nationally representative sample surveys. The financial cost is reported in terms of the annual incremental cost at health facility level, as well as its implications at national level, given the planned scale-up path. Secondly, economic cost is assessed as the total annual as well as annual per capita cost of services at HWC level. Bootstrapping technique was undertaken to estimate 95% confidence intervals for cost estimations. Scaling to CPHC through HWC would require an additional ₹ 721 509 (US$10 178) million allocation of funds for primary healthcare >5 years from 2019 to 2023. The scale-up would imply an addition to Government of India's health budget of 2.5% in 2019 to 12.1% in 2023. Our findings suggest a scale-up cost of 0.15% of gross domestic product (GDP) for full provision of CPHC which compares with current public health spending of 1.28% of GDP and a commitment of 2.5% of GDP by 2025 in the National Health Policy. If a capitation-based payment system was used to pay providers, provision of CPHC would need to be paid at between ₹ 333 (US$4.70) and ₹ 253 (US$3.57) per person covered for SHC and PHC, respectively.

Cost effectiveness of typhoid vaccination in India

INTRODUCTION

World Health Organization has prequalified the use of typhoid conjugate vaccine (TCV) in children over six months of age in typhoid endemic countries. We assessed the cost-effectiveness of introducing TCV separately for urban and rural areas of India.

METHODS

A decision analytic model was developed, using a societal perspective, to compare long-term costs and outcomes (3% discount rate) in a new-born cohort of 100,000 children immunized with or without TCV. Three vaccination scenarios were modelled, assuming the protective efficacy of TCV to last for 5, 10 and 15 years following immunization. Incidence of typhoid infection estimated under 'National Surveillance System for Enteric Fever' (NSSEFI)' was used. The prices of vaccine and cost of service delivery were included for vaccination arm. Both health system cost and out-of-pocket expenditures for treatment of typhoid illness and its complications was included.

RESULTS

TCV introduction in urban areas would result in prevention of 17% to 36% typhoid cases and deaths. With exclusion of indirect costs, the incremental cost per QALY gained was ₹ 151,346 (54,730-307,975), ₹ 61,710 (-5250 to 163,283) and ₹ 45,188 (-17,069 to 141,093) for scenario 1, 2 and 3 respectively. While, with inclusion of indirect costs, all 3 scenarios were cost saving. Further, in rural areas, TCV is estimated to reduce the typhoid cases and deaths by 19% to 36%, with ICER (incremental cost per QALY gained) ranging from ₹ 2340 (1316-4370) to ₹ 3574 (2057 - 6691) thousand (inclusive of indirect costs) among the 3 vaccination scenarios.

CONCLUSION

From a societal perspective, introduction of TCV is a cost saving strategy in urban India. Further, due to low incidence of typhoid infection, introduction of TCV is not cost-effective in rural settings of India.

Impact of COVID-19 on Outcomes for Patients With Cervical Cancer in India

PURPOSE

The COVID-19 pandemic has placed unprecedented demands on the health system. This led to delays in the initiation and completion of cancer treatment. We assessed the long-term health consequences because of the delay in diagnosis and treatment for cervical cancer due to COVID-19 in India.

METHODS

We used a Markov-model–based analysis assessing the lifetime health outcomes of the cohort of women population at risk from cervical cancer in India. The decrease in survival for those with the treatment interruption was calculated based on the number of days the treatment was extended beyond the standard duration. Furthermore, to model the impact of late diagnosis and delayed treatment initiation, the patients were assumed to have upstaged during the delay period, as per natural progression of disease.

RESULTS

We estimate 2.52% (n = 795) to 3.80% (n = 2,160) lifetime increase in the deaths caused by cervical cancer with treatment restrictions ranging from 9 weeks to 6 months, respectively, as compared to no delay. On the contrary, 88-238 deaths because of COVID-19 disease are estimated to be saved during this restriction period among the patients with cervical cancer. Overall, the excess mortality because of cervical cancer led to 18,159-53,626 life-years being lost and an increase of 16,808-50,035 disability-adjusted life-years.

CONCLUSION

Delays in diagnosis and treatment are likely to lead to more cervical cancer deaths as compared to COVID-19 mortality averted among the patients with cervical cancer. Health systems must reorganize in terms of priority setting for provision of care, starting with prioritizing the treatment of patients with early-stage cervical cancer, increasing use of teleconsultation, and strengthening the role of primary care physicians in provision of cancer care.

Adapting health technology assessment for drugs, medical devices, and health programs: Methodological considerations from the Indian experience

INTRODUCTION

Heterogeneity in methods of economic evaluation makes the use of health technology assessment (HTA) evidence difficult. Thereby, several countries including India have developed their own standard guidelines for conducting HTAs. However, diverse HTA studies involving drugs, medical devices, health programs, and platforms require an adaptation of the standard methods.

AREAS COVERED

This review presents the specific characteristics of HTAs involving medical devices and health programs requiring adaptation of the standard guidelines. We use recent HTA studies in India to illustrate specific issues. These considerations involve the nature of decision-making problems, multiple scenarios in case of health programs, and specific attention to costing and the valuation of consequences. In case of medical devices, we discuss the issue of costing application of devices, multiple usage, learning curve for achieving effects, long causal path for health outcomes, and the issue of valuing false positives.

EXPERT OPINION

While standard guidelines are essential, specific features of health programs and medical devices need to be considered while undertaking HTAs. Additionally, the context in which the HTA is being undertaken, characteristics of the health system, methods of financing healthcare, and demand-side characteristics of healthcare utilization should be reflected in the HTA for health programs and medical devices.

Cost analysis of pediatric intensive care: a low-middle income country perspective

Background

Globally, Pediatric Intensive Care Unit (PICU) admissions are amongst the most expensive. In low middle-income countries, out of pocket expenditure (OOP) constitutes a major portion of the total expenditure. This makes it important to gain insights into the cost of pediatric intensive care. We undertook this study to calculate the health system cost and out of pocket expenditure incurred per patient during PICU stay.

Methods

Prospective study conducted in a state of the art tertiary level PICU of a teaching and referral hospital. Bottom-up micro costing methods were used to assess the health system cost. Annual data regarding hospital resources used for PICU care was collected from January to December 2018. Data regarding OOP was collected from 299 patients admitted from July 2017 to December 2018. The latter period was divided into four intervals, each of four and a half months duration and data was collected for 1 month in each interval. Per patient and per bed day costs for treatment were estimated both from health system and patient’s perspective.

Results

The median (inter-quartile range, IQR) length of PICU stay was 5(3–8) days. Mean ± SD Pediatric Risk of Mortality Score (PRISM III) score of the study cohort was 22.23 ± 7.3. Of the total patients, 55.9% (167) were ventilated. Mean cost per patient treated was US$ 2078(₹ 144,566). Of this, health system cost and OOP expenditure per patient were US$ 1731 (₹ 120,425) and 352 (₹ 24,535) respectively. OOP expenditure of a ventilated child was twice that of a non- ventilated child.

Conclusions

The fixed cost of PICU care was 3.8 times more than variable costs. Major portion of cost was borne by the hospital. Severe illness, longer ICU stay and ventilation were associated with increased costs. This study can be used to set the reimbursement package rates under Ayushman Bharat – Pradhan Mantri Jan Arogya Yojana (AB-PMJAY). Tertiary level intensive care in a public sector teaching hospital in India is far less expensive than developed countries.

Cost-effectiveness of treating head and neck cancer using intensity-modulated radiation therapy: implications for cancer control program in India

Background

The newer cancer treatment technologies hold the potential of providing improved health outcomes at an additional cost. So it becomes obligatory to assess the costs and benefits of a new technology, before defining its clinical value. We assessed the cost-effectiveness of intensity-modulated radiotherapy (IMRT) as compared to 2-dimensional radiotherapy (2-DRT) and 3-dimensional radiotherapy (3D-CRT) for treating head and neck cancers (HNC) in India. The cost-effectiveness of 3-DCRT as compared to 2-DRT was also estimated.

Methods

A probabilistic Markov model was designed. Using a disaggregated societal perspective, lifetime study horizon and 3 percent discount rate, future costs and health outcomes were compared for a cohort of 1000 patients treated with any of the three radiation techniques. Data on health system cost, out of pocket expenditure, and quality of life was assessed through primary data collected from a large tertiary care public sector hospital in India. Data on xerostomia rates following each of the radiation techniques was extracted from the existing randomized controlled trials.

Results

IMRT incurs an incremental cost of $7,072 (2,932–13,258) and $5,164 (463–10,954) per quality-adjusted life year (QALY) gained compared to 2-DRT and 3D-CRT, respectively. Further, 3D-CRT as compared to 2-DRT requires an incremental cost of $8,946 (1,996–19,313) per QALY gained.

Conclusion

Both IMRT and 3D-CRT are not cost-effective at 1 times GDP per capita for treating HNC in India. The costs and benefits of using IMRT for other potential indications (e.g. prostate, lung) require to be assessed before considering its introduction in India.

Cost of Treatment for Cervical Cancer in India

INTRODUCTION

Cervical cancer is a major public health problem in India leading to high economic burden, which is disproportionately borne by the patients as out-of-pocket expenditure (OOPE). Several publicly financed health insurance schemes (PFHIs) in India cover the treatment for cervical cancer. However, the provider payment rates for health benefit packages (HBP) under these PFHIs are not based on scientific evidence. We undertook this study to estimate the cost of services provided for treatment of cervical cancer and  cost of the package of care for cervical cancer in India.

METHODS

The study was undertaken at a large public tertiary hospital in North India. The health system cost was assessed using a mixed micro-costing approach. The data were collected for all the resources utilized during service delivery for cervical cancer patients. To evaluate the OOPE, randomly selected 248 patients were interviewed following the cost of illness approach. Logistic regression was used to assess the factors associated with catastrophic health expenditure (CHE).

RESULTS

Health system cost for different cervical cancer treatment modalities i.e. radiotherapy, brachytherapy, chemotherapy and surgery, ranges from INR 19,494 to 41,388 (USD 291 - 617). Furthermore, patients spent INR 4,042 to 23,453 ( USD 60 - 350) as OOPE. Nearly 62% patients incurred CHE, and 30% reported distress financing. The odds of CHE (OR: 25.39, p-value: <0.001) and distress financing (OR: 15.37, p-value: 0.001) were significantly higher in poorest-income quintile. The HBP cost varies from INR 45,364 to 64,422 (USD 676 - 960) for brachytherapy and radiotherapy respectively.

CONCLUSION

Cervical cancer treatment leads to high OOPE in India, which imposes financial hardship, especially for the poorest. The coverage of risk pooling mechanisms like PHFIs should be enhanced. The findings of our study should be used to set the reimbursement rates of providing cervical cancer treatment under PFHI schemes.
