Effects of the Out-of-pocket Payment Exemption in the Public Health Center on Medical Utilization of the Korean Elderly.

OBJECTIVES: The distribution of hospitals in Korea is unbalanced in terms of accessibility. Many local public health centers (PHCs) exempt out-of-pocket payments (OOPs) based on local government laws to increase coverage. However, this varies across administrative regions, as many make this exemption for the elderly, while others do not. This study aimed to evaluate the effects of the OOP exemption at local PHCs among elderly individuals. METHODS: This study used online data on Korean national law to gather information on individual local governments' regulations regarding OOP exemptions. Individual-level data were gathered from the 2018 Community Health Survey and regional-level data from public online sources. RESULTS: The study analyzed 132 regions and 44 918 elderly people. A statistical analysis of rate differences and 2-level multiple logistic regression were carried out. The rate difference according to whether elderly individuals resided in areas with the OOP exemption was 1.97%p (95% confidence interval [CI], 1.07 to 2.88) for PHC utilization, 1.37%p (95% CI, 0.67 to 2.08) for hypertension treatment, and 2.19%p (95% CI, 0.63 to 3.74) for diabetes treatment. The regression analysis showed that OOP exemption had an effect on hypertension treatment, with a fixed-effect odds ratio of 1.25 (95% CI, 1.05 to 1.48). CONCLUSIONS: The OOP exemption at PHCs can affect medical utilization in Korea, especially for hypertension treatment. The OOP exemption should be expanded to improve healthcare utilization in Korea.

Association Between Convenience of Transportation and Unmet Healthcare Needs of Rural Elderly in Korea.

OBJECTIVES: In rural areas of Korea, where public transportation infrastructure is lacking and alternative systems are poor, the elderly experience inconveniences in using healthcare, although their need is high. This study aimed to analyze the association between the convenience of transportation and unmet healthcare needs among the rural elderly. METHODS: The data used were collected in the 2016 Community Health Survey among rural elderly individuals aged 65 or older. Dependent variable was the unmet healthcare needs, explanatory variable was the convenience of transportation. The elderly were divided into 3 groups: with no driver in the household, with a driver, and the elderly individual was the driver (the self-driving group). Covariates were classified into predisposing, enabling, and need factors. They included gender, age, education, income, economic activity, household type, motor ability, subjective health level, number of chronic diseases, anxiety/depression, and pain/discomfort. The data were analyzed using logistic regression and stratification. RESULTS: A significant association was found between the convenience of transportation and unmet healthcare needs. When examined unadjusted odds ratio of the group with a driver in the household, using the group with no driver as a reference, was 0.61 (95% confidence interval [CI], 0.54 to 0.68), while that of the self-driving group was 0.34 (95% CI, 0.30 to 0.38). The odds ratios adjusted for all factors were 0.69 (95% CI, 0.59 to 0.80) and 0.79 (95% CI, 0.67 to 0.91). CONCLUSIONS: We confirmed a significant association between inconvenient transportation and unmet healthcare needs among the rural elderly even after adjustment for existing known factors. This implies that policies aimed at improving healthcare accessibility must consider the means of transportation available.

Understanding of for whom, under what conditions and how the compulsory licensing of pharmaceuticals works in Brazil and Thailand: A realist synthesis.

When pharmaceuticals are not fully available mainly due to the high cost of medicines, a government can issue compulsory licensing (CL). It is well documented that Brazil and Thailand have notably attempted CL. A realist review was undertaken to understand the identical social interventions in comparative settings, and to draw practical implications for attempting CL relevant for middle-income countries in the era of high-cost medicines. CL is not only a politically well-devised measure to achieve universal health coverage, but also a tentative commitment, which is determined both at the country level and at the global level. At the country level, political will, with catalytic roles of civil activism, is important in order to guarantee the right to health. Through this will, the governments can achieve universal health coverage. In addition, electoral systems, political leaders, and a constitution are necessary to attempt CL. In addition, CL should operate along with other policy instruments, including a comprehensive essential medicines list, CL-friendly phrasing in patent law, and a competent pharmaceutical industry. At the global level, the balance of power between the WTO regime and the global justice movement is critical. This provides global-level context that can either encourage or prevent CL.

Employment Status and Self-Reported Unmet Healthcare Needs among South Korean Employees.

We aimed to examine the association between employment status and self-reported unmet healthcare needs and to identify factors influencing self-reported unmet healthcare needs by employment status. Nationally representative data from the 2012 Korea National Health and Nutrition Examination Survey were used. Participants were classified by employment status as either permanent or precarious workers. Explanatory variables included sociodemographic, labor-related, and health-related factors. Multivariate logistic regression ascertained the association between employment status and self-reported unmet healthcare needs and explanatory factors associated with self-reporting of unmet healthcare needs. Precarious workers had a higher prevalence of self-reported unmet healthcare needs than permanent workers, with a statistically significant odds ratio (OR) (1.74; 95% confidence interval (CI), 1.19⁻2.54). Male precarious workers working >40 h per week were more likely to self-report unmet needs than male precarious workers working <40 h (OR, 3.90; 95% CI, 1.40⁻10.87). Female precarious workers with a lower household income were about twice as likely to self-report unmet needs. Working hours and household income were significantly influential factors determining self-reporting of unmet healthcare needs, especially among precarious workers. Policy interventions to improve access to healthcare for precarious workers are needed.

Social capital as a key determinant of willingness to join community-based health insurance: a household survey in Nepal.

OBJECTIVES: Although community-based health insurance (CBHI) schemes have been considered as an intermediate stage to achieve universal health coverage (UHC) in low-resource settings, there is a knowledge gap on ways to make it better. STUDY DESIGN: More than 4000 Nepalese households were randomly selected and surveyed. METHODS: Logistic and multivariate multinomial regressions were estimated. RESULTS: Overall, 88% of included household heads were willing to join CBHI, 61% were willing to pay annual premium less than 600 Nepalese rupees (US$5.6) per household, and more than a half (53%) responded that the government should subsidize a significant portion of the premium. Results showed that a higher level of social capital was significantly related with an increase in odds of accepting higher premiums, while individuals' health status and age did not have such associations. Individuals with bonding social capital were more likely to be inclined to join CBHI. Persons who said they can lend money for a living expense (bonding capital) did not want the government to subsidize the scheme, while this negative association would be reversed if persons had both bonding and bridging social capitals. CONCLUSION: We found significantly positive relationships between social capital and willingness to join and willingness to pay for CBHI in Nepal. Policymakers, aiming to achieve UHC, should be advised that bonding and bridging social capital have differing relationships with willingness to cooperate the external funding sources.

Inequality in unmet dental care needs among South Korean adults.

BACKGROUND: The current public health research agenda was to identify the means to reduce oral health inequalities internationally. The objectives of this study were to provide evidence of inequality in unmet dental needs and to find influencing factors attributable to those among South Korean adults. METHODS: Pooled cross-sectional data from the fourth Korean National Health and Nutrition Examination Survey (2007-2009) on 17,141 Korean adults were used. Demographic factors (sex, age, and marital status), socioeconomic factors (education level, employment status, and income level), need factors (normative dental needs and self-perceived oral health status), and oral health-related factors (the number of decayed teeth, the presence of periodontitis, and the number of missing teeth) were included. Multiple logistic regression analysis was performed. RESULTS: Of South Korean adults, 43.9% had perceived unmet dental needs, with the most common reason being financial difficulties. The disparities in unmet dental care needs were strongly associated with income level, normative treatment needs, and self-perceived oral health status. The low-income group, people with normative dental treatment needs, and those with perceived poor oral health status were more likely to have unmet dental needs. There was considerable inequality in unmet dental care needs due to economic reasons according to such socioeconomic factors as income and education level. CONCLUSIONS: Public health policies with the expansion of dental insurance coverage are needed to reduce inequalities in unmet dental care needs and improve the accessibility of dental care services to vulnerable groups who are experiencing unmet dental care needs due to socioeconomic factors despite having normative and self-perceived needs for dental treatment.

Do antenatal care visits always contribute to facility-based delivery in Tanzania? A study of repeated cross-sectional data.

There is a known high disparity in access to perinatal care services between urban and rural areas in Tanzania. This study analysed repeated cross-sectional (RCS) data from Tanzania to explore the relationship between antenatal care (ANC) visits, facility-based delivery and the reasons for home births in women who had made ANC visits. We used data from RCS Demographic and Health Surveys spanning 20 years and a cluster sample of 30 830 women from ∼52 districts of Tanzania. The relationship between the number of ANC visits (up to four) and facility delivery in the latest pregnancy was explored. Regional changes in facility delivery and related variables over time in urban and rural areas were analysed using linear mixed models. To explore the disconnect between ANC visits and facility deliveries, reasons for home delivery were analysed. In the analytic model with other regional-level covariates, a higher proportion of ANC (>2-4 visits) and exposure to media related to an increased facility delivery rate in urban areas. For rural women, there was no significant relationship between the number of visits and facility delivery rate. According to the fifth wave result (2009-10), the most frequent reason for home delivery was 'physical distance to facility', and a significantly higher proportion of rural women reported that they were 'not allowed to deliver in facility'. The disconnect between ANC visits and facility delivery in rural areas may be attributable to physical, cultural or familial barriers, and quality of care in health facilities. This suggests that improving access to ANC may not be enough to motivate facility-based delivery, especially in rural areas.

Civic participation and self-rated health: a cross-national multi-level analysis using the world value survey.

OBJECTIVES: Civic participation, that which directly influences important decisions in our personal lives, is considered necessary for developing a society. We hypothesized that civic participation might be related to self-rated health status. METHODS: We constructed a multi-level analysis using data from the World Value Survey (44 countries, n=50 859). RESULTS: People who participated in voting and voluntary social activities tended to report better subjective health than those who did not vote or participate in social activities, after controlling for socio-demographic factors at the individual level. A negative association with unconventional political activity and subjective health was found, but this effect disappeared in a subset analysis of only the 18 Organization for Economic Cooperation and Development (OECD) countries. Moreover, social participation and unconventional political participation had a statistically significant contextual association with subjective health status, but this relationship was not consistent throughout the analysis. In the analysis of the 44 countries, social participation was of borderline significance, while in the subset analysis of the OECD countries unconventional political participation was a stronger determinant of subjective health. The democratic index was a significant factor in determining self-rated health in both analyses, while public health expenditure was a significant factor in only the subset analysis. CONCLUSIONS: Despite the uncertainty of its mechanism, civic participation might be a significant determinant of the health status of a country.

Difference in adherence to and influencing factors of a healthy lifestyle between middle-aged and elderly people in Korea: A multilevel analysis.

AIM: Comprehensive research for factors related to healthy lifestyles of the elderly is limited. The present study aimed to elucidate the factors associated with adherence to a healthy lifestyle by age groups. METHOD: The present study was based on data from the 2005 Korea National Health and Nutrition Examination Survey. We calculated crude proportions and adjusted proportions of cigarette smokers, problem alcohol drinkers, and physically inactive people in two age groups (40-59 years and ≥60 years). We carried out multilevel analysis to elucidate factors associated with healthy lifestyles. RESULTS: Of 3194 respondents included in the analysis, 1154 (36.13%) were aged 60 years or older. Older participants smoked less (23.0% vs 17.4%) and exercised less frequently (52.4% vs 66.9%; all P < 0.001) than their middle-aged counterparts. After adjustment, the proportion of regular exercisers was inversed (adjusted proportion 0.468, 95% CI 0.436-0.501 vs 0.377, 95% CI 0.337-0.419, P = 0.004). In multilevel analysis, contextual factors, such as local tax per capita, was associated significantly with cigarette smoking only in the elderly (OR 1.037, 95% CI 1.005-1.070). CONCLUSIONS: Different factors were associated with healthy lifestyles of elderly people when compared with middle-aged people. In addition, local tax per capita, an area level variable, was more likely to be associated with smoking in the elderly than the middle-aged group.

Public participation in the process of local public health policy, using policy network analysis.

OBJECTIVES: To assess the current public participation in-local health policy and its implications through the analysis of policy networks in health center programs. METHODS: We examined the decision-making process in sub-health center installations and the implementation process in metabolic syndrome management program cases in two districts ('gu's) of Seoul. Participants of the policy network were selected by the snowballing method and completed self-administered questionnaires. Actors, the interactions among actors, and the characteristics of the network were analyzed by Netminer. RESULTS: The results showed that the public is not yet actively participating in the local public health policy processes of decision-making and implementation. In the decision-making process, most of the network actors were in the public sector, while the private sector was a minor actor and participated in only a limited number of issues after the major decisions were made. In the implementation process, the program was led by the health center, while other actors participated passively. CONCLUSIONS: Public participation in Korean public health policy is not yet well activated. Preliminary discussions with various stakeholders, including civil society, are needed before making important local public health policy decisions. In addition, efforts to include local institutions and residents in the implementation process with the public officials are necessary to improve the situation.

Association between local government social expenditures and mortality levels in Korea.

OBJECTIVES: We examined the association between social expenditures of the local government and the mortality level in Korea, 2004 to 2010. METHODS: We used social expenditure data of 230 local governments during 2004 to 2010 from the Social Expenditure Database prepared by the Korean Institute for Health and Social Affairs. Fixed effect panel data regression analysis was adopted to look for associations between social expenditures and age-standardized mortality and the premature death index. RESULTS: Social expenditures of local governments per capita was not significantly associated with standardized mortality but was associated with the premature death index (decline of 1.0 [for males] and 0.5 [for females] for each expenditure of 100 000 Korean won, i.e., approximately 100 US dollar). As an index of the voluntary effort of local governments, the self-managed project ratio was associated with a decline in the standardized mortality in females (decline of 0.4 for each increase of 1%). The share of health care was not significant. CONCLUSIONS: There were associations between social expenditures of the local government and the mortality level in Korea. In particular, social expenditures per capita were significantly associated with a decline in premature death. However, the voluntary efforts of local governments were not significantly related to the decline in premature death.

Contribution of income-related inequality and healthcare utilisation to survival in cancers of the lung, liver, stomach and colon.

OBJECTIVES: To examine differences in the survival rates of cancer patients according to socioeconomic status, focusing on the role of the degree of healthcare utilisation by the patient. METHODS: An observational follow-up study was done for 261 lung cancer, 259 liver cancer, 268 stomach cancer and 270 colon cancer patients, diagnosed during 1999-2002. Income status and healthcare utilisation were assessed with National Health Insurance (NHI) data; survival during 1999-2002 was identified by death certificate. HRs and 95% CI were derived from Cox proportional hazards regression. RESULTS AND CONCLUSIONS: The HRs for low income status are larger for colon cancer (2.37, 95% CI 1.17 to 4.80), followed by stomach (1.67, 95% CI 1.01 to 2.78), liver (1.57, 95% CI 1.03 to 2.39) and lung cancers (1.46, 95% CI 0.99 to 2.14). In the model including the variable of healthcare utilisation, colon and stomach cancers exhibited a lower HR in the moderate healthcare utilisation groups (0.40, 95% CI 0.21 to 0.76 in colon; 0.59, 95% CI 0.37 to 0.96 in stomach), whereas for liver cancer, the high utilisation group exhibited a higher hazard (1.72, 95% CI 1.07 to 2.75). A lower income status is independently related to a shorter survival time in cancer patients, especially in less fatal cancers. Healthcare utilisation independently affects the likelihood of survival from colon and stomach cancers, implying that a moderate degree of healthcare utilisation contributes to a longer survival time.

Disparities in health care utilization among urban homeless in South Korea: a cross-sectional study.

OBJECTIVES: We examined health care disparities in Korean urban homeless people and individual characteristics associated with the utilization of health care. METHODS: We selected a sample of 203 homeless individuals at streets, shelters, and drop-in centers in Seoul and Daejeon by a quota sampling method. We surveyed demographic information, information related to using health care, and health status with a questionnaire. Logistic regression analysis was adopted to identify factors associated with using health care and to reveal health care disparities within the Korean urban homeless population. RESULTS: Among 203 respondents, 89 reported that they had visited health care providers at least once in the past 6 months. Twenty persons (22.5%) in the group that used health care (n = 89) reported feeling discriminated against. After adjustment for age, sex, marital status, educational level, monthly income, perceived health status, Beck Depression Inventory score, homeless period, and other covariates, three factors were significantly associated with medical utilization: female sex (adjusted odds ratio [aOR, 15.95; 95% CI, 3.97 to 64.04], having three or more diseases (aOR, 24.58; 95% CI, 4.23 to 142.78), and non-street residency (aOR, 11.39; 95% CI, 3.58 to 36.24). CONCLUSIONS: Health care disparities in Seoul and Daejeon homeless exist in terms of the main place to stay, physical illnesses, and gender. Under the current homeless support system in South Korea, street homeless have poorer accessibility to health care versus non-street homeless. To provide equitable medical aid for homeless people, strategies to overcome barriers against health care for the street homeless are needed.

The financial burden of asthma: a nationwide comprehensive survey conducted in the republic of Korea.

PURPOSE: Asthma-related morbidity and mortality are increasing, and the financial burden imposed by this condition will substantially increase. Nevertheless, little information is available regarding the nature and magnitude of the burden due to asthma at the national level. This study was conducted to characterize the financial burden imposed by asthma in the Republic of Korea at the national level. METHODS: The overall prevalence of asthma and the costs of related medical services were determined using data from the National Health Insurance Corporation, which is responsible for the National Health Insurance scheme. Indirect costs, including expenditures on complementary and alternative medicines, and the economic impact of an impaired quality of life (intangible costs) were estimated by surveying 660 asthmatics, and these estimates were transformed to the national level using the prevalence of asthma. RESULTS: The prevalence of asthma and total costs related to the disease in 2004 were 4.19% and $2.04 billion, respectively. Direct costs and indirect costs contributed equally to total costs (46.9% and 53.1%, respectively). However, when intangible costs were included, total costs rose to $4.11 billion, which was equivalent to 0.44% of the national gross domestic product in 2004. CONCLUSIONS: The results provide evidence that asthma is a major health cost factor in the Republic of Korea and that intangible costs associated with asthma are significant cost drivers.

Participation determinants in the DRG payment system of obstetrics and gynecology clinics in South Korea.

OBJECTIVES: The Diagnosis Related Group (DRG) payment system, which has been implemented in Korea since 1997, is based on voluntary participation. Hence, the positive impact of this system depends on the participation of physicians. This study examined the factors determining participation of Korean obstetrics & gynecology (OBGYN) clinics in the DRG-based payment system. METHODS: The demographic information, practice-related variables of OBGYN clinics and participation information in the DRG-based payment system were acquired from the nationwide data from 2002 to 2007 produced by the National Health Insurance Corporation and the Health Insurance Review & Assessment Service. The subjects were 336 OBGYN clinics consisting of 43 DRG clinics that had maintained their participation in 2003-2007 and 293 no-DRG (fee-for-service) clinics that had never been a DRG clinic during the same period. Logistic regression analysis was carried out to determine the factors associated with the participation of OBGYN clinics in the DRG-based payment system. RESULTS: The factors affecting participation of OBGYN clinics in the DRG-based payment system were as follows (p<0.05): (1) a larger number of caesarian section (c/sec) claims, (2) higher cost of a c/sec, (3) less variation in the price of a c/sec, (4) fewer days of admission for a c/sec, and (5) younger pregnant women undergoing a c/sec. CONCLUSIONS: These results suggest that OBGYN clinics with an economic practice pattern under a fee-for-service system are more likely to participate in the DRG-based payment system. Therefore, to ensure adequate participation of physicians, a payment system with a stronger financial incentive might be more suitable in Korea.

[High risk groups in health behavior defined by clustering of smoking, alcohol, and exercise habits: National Heath and Nutrition Examination Survey].

OBJECTIVES: We investigated the clustering of selected lifestyle factors (cigarette smoking, heavy alcohol consumption, lack of physical exercise) and identified the population characteristics associated with increasing lifestyle risks. METHODS: Data on lifestyle risk factors, sociodemographic characteristics, and history of chronic diseases were obtained from 7,694 individuals >/=20 years of age who participated in the 2005 Korea National Health and Nutrition Examination Survey (KNHANES). Clustering of lifestyle risks involved the observed prevalence of multiple risks and those expected from marginal exposure prevalence of the three selected risk factors. Prevalence odds ratio was adopted as a measurement of clustering. Multiple correspondence analysis, Kendall tau correlation, Man-Whitney analysis, and ordinal logistic regression analysis were conducted to identify variables increasing lifestyle risks. RESULTS: In both men and women, increased lifestyle risks were associated with clustering of: (1) cigarette smoking and excessive alcohol consumption, and (2) smoking, excessive alcohol consumption, and lack of physical exercise. Patterns of clustering for physical exercise were different from those for cigarette smoking and alcohol consumption. The increased unhealthy clustering was found among men 20-64 years of age with mild or moderate stress, and among women 35-49 years of age who were never-married, with mild stress, and increased body mass index (>30 kg/m(2)). CONCLUSIONS: Addressing a lack of physical exercise considering individual characteristics including gender, age, employment activity, and stress levels should be a focus of health promotion efforts.

Health technology assessment in South Korea.

OBJECTIVE: To analyze evolution of the health technology assessment (HTA) at the national level in South Korea. METHODS: Analysis of public documents, personal communication, and literative review. RESULTS: HTA in South Korea has been developed since 1990s, first introduced by academia and institutionalized within the National Health Insurance (NHI). Rapidly increasing expenditure had been a challenge of the NHI, which considered health technology management as a cost controlling measure. An amendment was made to the NHI Law in 2000, and provision was made to regulate the process of determining new insurance benefits including procedures, drugs, and equipment. This requirement made the NHI agencies to promote HTA approaches in connection with the government and professional organizations. Also the Healthcare Act was revised in October 2006 ruling that HTA focusing on safety and effectiveness be responsible for new health technologies. Currently, the HTA process is governed by a governmental committee comprising twenty members and technically supported by the HTA center created in the NHI structure. CONCLUSIONS: Institutionalized HTA in Korea has been driven mainly by the requirements of the NHI and manifested strengths as well as weaknesses. The government is establishing a new organization for HTA, independent from the NHI.

[Subjective satisfaction with medical care among older people: Comprehensiveness, general satisfaction and accessibility].

OBJECTIVES: The changing population age structure and rapidly increasing medical costs make providing high-quality, effective medical care for the elderly a challenge. This study assessed the satisfaction with medical care in terms of comprehensiveness, general satisfaction, and accessibility among community-dwelling Korean elders. METHODS: Data were obtained from a nationwide representative sample of the older adults(aged 65 years old or older) living in the community, who participated in a 2006 telephone survey conducted using random digit dialing (n=881). General satisfaction, comprehensiveness and accessibility were measured using a 10-item satisfaction survey questionnaire. Descriptive analysis was used to assess the distribution of each of three components of subjective satisfaction. Analysis of covariance (ANCOVA) was used to examine the association of each of the three components with socioeconomic variables. RESULTS: Comprehensiveness and general satisfaction were low among older people with a high socioeconomic status. Accessibility was evaluated as low among older people of low socioeconomic status, those living in rural areas and those who were medical aid beneficiaries. CONCLUSIONS: Urgent interventions should be considered in order to improve accessibility to medical care for elders of low socioeconomic status and those living in rural communities. Given the rapid aging of the population, we need to develop a monitoring system to improve the quality of geriatric care.

Trends in patient satisfaction from 1989-2003: adjusted for patient characteristics.

PURPOSE: To identify trends in patient satisfaction adjusted for sociodemographic factors and health status from 1989-2003. METHODS: Five repeated cross-sectional surveys were used. The study sample included 290,534 household members 20 years of age and over from the five survey periods of 1989, 1992, 1995, 1999, and 2003. Satisfaction was measured using a five-point scale, ranging from "very satisfied" to "very dissatisfied." Crude satisfaction rates, representing the proportion of patients satisfied (very satisfied or satisfied), were calculated for each survey period. Satisfaction rates adjusted for age, sex, marital status, education, and self-rated health status were calculated for each of the five years. RESULTS: Crude satisfaction rates increased from 15.4% in 1989 to 40.5% in 2003. The proportions of satisfaction and dissatisfaction were reversed after 15 years had passed. However, the satisfaction trend was not linear throughout the different years, with 1992 being the year with the lowest satisfaction rate (9.7%). These trends in crude rates did not change even after adjusting for patient characteristics. The odds of satisfaction in 1992 were 38% lower (odds ratio 0.62, 95% CI 0.60 to 0.64) than the odds in 1989. In 2003, the odds of satisfaction were 4.01 times (95% CI 3.89 to 4.13) the odds for 1989. Older, female, married, and less-educated people were more likely to be satisfied. Patients who rated their health as "very good" had the highest satisfaction rate, and those with "neutral" health ratings had the lowest. General hospitals achieved substantial improvement whereas pharmacies became the lowest-rated of all institutions. CONCLUSIONS: The Korean health system has achieved better patient satisfaction rates over the past 15 years. Increased health expenditure, resources, and quality improvement efforts may have contributed to this progress.
