3 1 INTRODUCTION Payment method (PM) is one of the five important components to improve the efficiency and equity of the health system. PM has an important role in the connection between health finance and the provision of health services (HS), this is a key task to control the health expenditure and quality of health-care services by creating the appropriate promoted mechanisms. In Vietnam, PM is an important issue for financial mechanisms at the supply health service facilities. Nowadays, fee-for-service payment is still mainly PM applying for HS in general as well as health insurance services in particular. With this PM, it is extremely difficult to control the health expenditures due to the nature of fee-for- service PM which is to encourage health facilities to supply as many services as beneficial. The law on health insurance has stipulated three pricipal methods of health expenditures using health insurance are capitation, fee-for-service, and case-based reimbursement. The Ministry of Health and Ministry of Finance have defined a roadmap of capitation PM. According to the roadmap, all of the registered primary health care facilities has follow the capitation PM, starting in Commune Health Station (CHS) is one of the registered primary health care services at the commune level. Worldwide, the most advanced and optimal PM for primary health care service is the capitation PM, because it works towards health care activities for the people to the preventive medicine activities, and promotes people s health, and manages chronic diseases at the community level.

4 2 Capitation PM is now applying in Vietnam which has many shortcomings both in the design, the practical implementation, and the impact. To provide the updated scientific evidence for the development, and perfection of the health expenditures followed the health insurance capitation in the CHSs, and can be applied at scales larger, we have conducted the research project "Health insurance based capitation payment model for health-care expenditures at some commune health stations in Dak To district of Kon Tum province" with the following objectives: (1) Describe the situation of fee-forservice payment method using health insurance at some CHSs of Kon Tum province in the period of ; (2) Evaluate the effectiveness on some health care indicators, appropriate prescription, and health care expenditure control of health insurance capitation PM at some CHSs in Dak To district, Kon Tum province. * The novelty of the thesis: 1. Described the situations of health insurance payment method by fee-for-service at some CHSs of Kon Tum province in the period of Contributed to the development of the health insurance expenditure under capitation PM model in some pilot CHSs followed the general principles of the world and in accordance with the practice in Vietnam, as well as the effective pilot model evaluated. 3. Provided the updated scientific and practical evidence in the PM innovation of health service expenditure, especially the development, modification and finalization of the instructions

5 3 of health insurance capitation PM. It contributes to the Health Insurance Law implementation successfully in the Universal Health Coverage Strategy by 2020 in Vietnam. Thesis structure: The main part of the thesis consists of 150 pages (not including covers, acknowledgment, annex, references, index), including Introduction: 2 pages, Objectives: 1 page; Chapter 1: Background: 48 pages, Chapter 2: Method: 26 pages, Chapter 3: Results: 40 pages, Chapter 4: Discussion: 30 pages, Conclusions: 2 pages, and Recommendations: 1 page. The thesis has 41 tables, 3 pictures, and 3 charts. There are 106 references, of which 55 Vietnamese references, and 51 English references. Chapter 1 BACKGROUND 1.1. Health service payment method in the world Primary health care payment methods There are three main payment methods for primary health care, including Line-item budget, fee-for-service and capitation Hospital payment methods There are five major hospital payments. The two methods have been mentioned above (line-item budget, and fee-forservice) that can be applied to inpatient services. Three different methods are daily treatment, case-based, and the total budget Payment methods in Vietnam PM for health care expenditure in our country has experienced a long period of budget allocations followed line-item budget (patient s beds and areas of payroll for preventive medicine).

6 4 Since the policy of partial charges was changed in 1989, feefor-service PM, an added method has been applying in parallel with the budget allocation method. It gradually becomes the main PM in the health care system. Capitation PM has piloted in 2005, with the growing scale of the number of establishments and service facilities. Case-based PM has only tested for some group diseases, and it is now preparing the required database for the development and applying at a larger scale. Operational results based PM has only pilot in several communes in Nghe An province. Under general direction, the effort to develop and perfect the various PM to supplement and replace the fee-for-service PM are being implemented The research on and experiences of capitation payment method Thailand is one of the countries that has successfully applied the capitation PM for health expenditures. Historically, health service expenditure PM in Thailand, the capitation PM is applied for the first time in 1991 in health and social insurance system applied to the private sector. Meanwhile, capitation payment is applicable to both outpatient and inpatient health care services. Ten years later, when the Universal Health Coverage program was being implemented, capitation PM was used as a limitation for outpatient health services. According to the experts of Thailand, the application of capitation payment for inpatient treatment area may affect the rights of patients by the risk of service reduction to patients during hospitalization. Capitation PM is considered a fairly successful program in the Universal Health Coverage Program in Thailand. The application of capitation PM in Thailand has

7 5 been effective when the service providers develop health care network at the community to limit treatment services at the hospital. The scale for capitation payment only includes outpatient services but do not include the diseases with big expenditures. Capitation payment rate is determined based on the frequency of use of outpatient services in the year, and the average expenditure for one outpatient health examination. Due to the limited data one expenditures, Thailand uses the fee-forservice expenditure to calculate the average expenditure. The average expenditure was adjusted for age and gender. Capitation fund allocated to the district health centers (DHC) includes expenditure for outpatient health care in the higher level of referral. A recent study in Thailand has demonstrated financial resources shifted from provincial to district level, and has brought many benefits to the poor living in Thailand. During the implementation process under capitation payment, monitoring, especially the indicators of utilize, and quality of health care service, are particularly focused. Thanks to the good information system, the monitoring of utilize indicator, expenditure, and quality of service are updated completely and regularly. Results of monitoring and evaluation showed that the capitation payment increased the original name of drugs, more appropriate diagnosis and treatment. It is, therefore, reducing the treatment expenditure and increasing the efficiency of health service provision Study locations Chapter 2 METHODS

8 Districts, communes for the intervention: Dak To district was purposely selected for the pilot. Selection criteria the pilot intervention communes are: (i) Health insurance participation rate and primary health care registration at the CHSs account for 70% or more of the population; (ii) The communes have medical doctor and health workers in CHSs commit to implement the model; (iii) The CHSs have computers and staff have good skills on computer in order to manage the health insurance expenditure software; and (iv) the distance from the commune to the district hospital is not too close ( 10 km) to limit the pass line in health examination. With the above criteria, we selected 3 communes (Ngoc Tu, Dak Nga, and Dak Tram) as intervention communes District, communes for control: Selection criteria the district, communes for control include: (i) The district has similar socio-economic conditions social and ethnic groups with the intervention district; (ii) DHC has district hospital to provide directly health care support for CHSs in health insurance; (iii) Health insurance participation rate and primary health care registration at the CHSs account for 70% or more of the population, the CHSs have medical doctors; and (iv) the distance from the commune to the district hospital is not too close ( 10 km) to limit the pass line in health examination. The Kon Ray district was selected as control district, in which 3 communes namely Dak Tre, Dak Pne, and Dak Khoi were selected as control communes Study time: From October 2011 to May 2014, in which intervention in 2012 and data collection in the field from April to July, 2013.

10 8 referral rate, over-estimated frequency of health examination, the people are more reliable, and satisfied on health services provided by the CHSs after the intervention, capitation fund are secured and remaining. - Research on the completed health service expenditure at the CHSs: This is the supplement study for the above studies to identify the current investment to guide the prioritized financial investment for CHSs operation, health service cost adjusting and capitation fund calculation for CHSs. Quantitative Intervention activities and capitation formula Intervention activities: Intervention activities were implemented from 01/01 to 31/12/2012 with the following key activities: Iinterdisciplinary between Department of Health and Provincial Social Insurance issued the plan for the pilot project; training for related staff in different levels on capitation PM application and improving quality of health services; adding human resources for health care by health insurance between district social insurance and DHC, of which clearly stated articles on capitation PM in the CHSs; monitoring; evaluate and report the pilot model Capitation formula * Formula for fixed expenditure identification: C = fx(m1+m2+s+v1) = fxu Of which: C is the fixed expenditure for one health insurance people; f is the frequency quota for health examination/card/year in the CHSs (an estimation of 1.0); U = (M1+M2+S+V1), is the average medicine expenditure for one health examination in CHSs; M1 is the medicine expenditure

11 9 for one health examination; M2 is the average technical service expenditure/health examination (the value is now 0, it will be identified later); S is fee for health examination; V1 is consumable equipment. * Fixexd fund for each CHSs: Fixed fund = (NxC)+(NxA- Pfund) Of which: Fixed fund is capitation fund; N is the number of health insurance cards registered for primary health care in the CHSs; C is fixed fund per card; A-P fund is the adjustingpromoting fund, equal to 10.0% of C Study subjectives: Health insurance services in the 6 study CHSs; Outpatient prescriptions have antibiotics in 2011 and 2012 of the 6 CHSs; people aged 18 years old using health insurance were health examination and treatment of the 6 CHSs in 2012; representatives of staff involved in the pilot model and the provincial, district, and commune level; financial expenditures for goods and bought services in the 6 study CHSs in Sample size Descriptive study: Health insurance health care and health care expenditure indicators in 2011 and 2012 of the registered health insurance people of the 6 CHSs and the 2 districts Research on the appropriated prescriptions - Using the sample size formula to compare two prevelances: - Of which: n is the minimum sample size; Z (1-α/2) : with 95% confident interval (CI), two way test, Z (1-α/2) = 1,96; p =

12 10 (p 1 +p 2 )/2; 1-β is the sample power, in this study 1-β = 85%; p 1 : The increase of appropriated prescription prevalence after intervention compared to before the intervention in the intervention communes, estimating p 1 =10%; p 2 : The increase of appropriated prescription prevalence after intervention compared to before the intervention in the control communes, estimating p 2 =3%. - Replacing the numbers to the formula, we have n = 222, this number will be multiplied with 2, the coefficient sample design, the sample size will be 444. It is rounded 450 prescriptions will be investigated before and after the intervention in each group. Thus, 150 prescriptions will be assessed before the intervention, and 150 prescriptions will be assessed after the intervention in each CHS Research on the satisfaction of the patients - Using the sample size formula to compare two prevelances: - Of which: n is the minimum sample size; Z (1-α/2) : with 95% confident interval (CI), two way test, Z (1-α/2) = 1,96; p = (p 1 +p 2 )/2; 1-β is the sample power, in this study 1-β = 85%; p 1 : The prevalence of the patient satisfied with the heath services of the intervention CHSs after the intervention, estimating p 1 = 85%; p 2 : The prevalence of the patient satisfied with the heath services of the control CHSs in post-test, estimating p 2 =70%. - Replacing the numbers to the formula, we have n = 138, this number will be multiplied with 2, the coefficient sample design, the sample size will be 276 people. Thus, 92 patients in 2012 will be interviewed in each commune. In fact, totally 636

13 11 people (Ngoc Tu: 107, Dak Ro Nga: 106, Dak Tram: 104, Dak Tre: 108, Đak Pne: 106 và Đak Koi: 105) were interviewed Qualitative research: In-depth interview: 7 interviews; Group discussions: Research on the full expenditure of health care services of the CHSs: Full expenditure of health care services in 2012 of the 6 CHSs Sampling method: Purposively cluster sampling followed 3 steps: the 1 st step: select intervention and control district, the 2 nd step: select 3 communes for intervention, 3 communes for control, the 3 rd step: select sample units Variables, indicators and the research contents: Based on the objectives of the study, and the sub-studies, key variables, indicators, and contents will be identified Data management and analysis - For the descriptive study and the full expenditure of health care services of the CHSs, the collected data will be clean, and entered to the MS Excel 2007 for calculation later on. For the research on the appropriated prescriptions and the satisfaction of the patients, the information will be coded, clean before entering using Epidata 3.1. The STATA software will be used for analysis. - All of the health insurance health services in 2011 will be adjusted to the cost of 2012 based on the consumer index published by the General Statistics - Some formula used in the study + Formula for average expenditure/health examination

14 12 x i X = Of which: X is average expenditure/health examination; x i is the money paid for the health examination followed i (i= the number of health examination: 1, 2...); n 1 is the total number of health examination in the CHSs yearly + Formula for average expenditure/card/year: n 1 Y = y i Of which: Y is the average expenditure/card/year; y i is the money paid for health examination followed i (i= the number of health examination: 1, 2...); n 2 is the number of registered card for primary health examination in the CHSs in the year. + Formula for increased proportion between 2012 and 2011: Increased proportion (%) = n 2 (Indicator Indicator 2011) x 100 Indicator Stata software will be used to test the different between variables in 2011 and 2012 by the following tests: Wilcoxon signed-rank test for abnormal distribution data; Z test for two prevalence; ( 2) or fisher s exact test for category variables more than 1 group; Mann-Whitney test for quantitative variables in the two independent groups; the statistically significance at 5.0% (p<0.05). - Logistic regression model between the satisfaction of the patients and some related factors will be built.

15 13 - Qualitative data will be categorized by topics for further analysis Ethics: The study s proposal has been approved by the Scientific and Ethic in Human Research Committee at the National Institute of Hygiene and Epidemiology.

22 Qualitative research: Almost all of the ideas and comments obtained from indepth-interviews and group discussions agreed that the capitation health insurance pilot model at the CHSs is effective, especially the improved health examination services, reducing the referall, total times of health examinations were out of the expectation, the people are more satisfy with the heath services at the CHSs compared to before the intervention. Capitation fund at the CHSs are secured and remaining Full expenditures of health care services at the CHSs Table 3.35: Comparison of unit expenditure and maximum fees Content 1. Regular expenditure (not include medicine and consumable equpiment) 2. Invested expenditure and regular expenditure (not include medicine and consumable equpiment) Actual expenditure (1000 VND) Maximum fees followed the Circular no. 4 (not include medicine and consumable equipment) Expenditure (1000 VND) Maximum fund proportion/ actual expenditure (%) The talbe 3.35 compared the unit expenditure (not include medicine and consumable equpiment) and the corresponding maximum service fees (not include medicine and consumable equpiment) followed the Circular no.4 of the Ministry of

23 21 Heatlh and Ministry of Finance. The hospital fees are very low in comparison with the unit expenditure of the provided services. For the unit expenditure only regular expenditure was calculated, the proportion of average taken back expenditure of the 6 CHSs is 6.2%. For the unit expenditure, including both invested expenditure, and regular expenditure, the proportion of average taken back expenditure of the 6 CHSs is 5.4%. Chapter 4 DISCUSSION 4.1. Situation of fee-for-service health insurance health care payment method in some CHSs The table 3.1 showed that the total health examinations, average health examinations, and the frequency/card/year of the three CHSs of Kon Ray district in 2012 all increased in comparison with in This is the evidence that the health insurance implementation at the CHSs has initially certain effective. Almost all of the people participating at health insurance registered for primary health care at the CHSs. They are more trusted to the health care services provided by the CHSs than before. Compared to 2011, the proportion of referall in 2012 decreased 13.3% (p<0.05). This is added evidence that almost all of the common diseases can be treated at the CHSs. The CHSs only sent severe disease patients, and cannot be treated at the CHSs to DHC for health examinations. The talbe 3.2 showed that medicine cost, accounting for 97-98%, is the main expenditure of the structure of health insurance health examination expenditure, consumable

24 22 equipment and technical-service costs take small proportions. The study s results showed that the total health insurance health care at the 3 CHSs of Kon Ray district in 2012 increased 28.0% compared with in 2011, of which all of the sub-totals increased. The increase can be explained by the increase of health examinations at the CHSs because the average cost/health examination in 2011 and 2012 is similar (81,000VND). However, average expenditure/card in 2012 was 25.9% higher than that in This is completely exact with the argument of fee-for-service PM that health examination expenditure is increasing regularly The effectiveness of capitation health insurance health care PM at some CHSs of Dak To district Prescription appropriately: Comparing the increased proportions of some prescription indicators at CHSs of the two districts between 2012 and 2011 (Table 3.9) found that the proportions of the prescriptions having domestic antibiotics, and the increased proportions of prescriptions having original medicines of Dak To district were higher than that of Kon Ray district. On the other hand, the increased proportions of the prescriptions having both original and branch names, and using antibiotics 4 days of Kon Ray district were higher in Dak To (all of the differences are statistically significant). They are good evidence of the effective interventions in the intervention group compared with the control group. Comparing the increased proportions of total prescriptive indicators at CHSs of the two districts between 2012 and 2011

25 23 (table 3.12) found that the increased proportions of average number of medicines/prescription, and antibiotics appropriated with diagnoses between the two districts are statistically significant differences (p<0.05). The increased proportion of average number of medicines/prescriptions of Dak To district was less than in Kon Ray district, and higher increased proportion of prescriptions having antibiotics appropriated with diagnose in Dak To district than in Kon Ray district was reported. It is, therefore, applying capitation health insurance can control the increasing of medicines. By doing this, the health insurance health examination expenditure is less increased and more appropriate antibiotic prescription is made The satisfactions of the patients: In the multiple logistic regression model (table 3.17), in order to control the confounding factors (all of the factors are considered similarly), the service users in the intervention district are 2.3 times higher satisfaction than that in the control district (OR = 2.3; 95%CI: ). The result showed that the pilot model has clear and good effectiveness Some health insurance health examination indicators: Since comparing the increased proportions of some health insurance health examination indicators at the CHSs of the two districts between 2012 and 2011 (Table 3.20) we found statistically sifnificant differences with p<0.05, of which all of the proportions of Dak To district were less increased in comparison to the Kon Ray district. This suggests that comparing with the CHSs applying fee-for-service health insurnace, the CHSs applying capitation health insurance were

26 24 better controlled the increased health care indicators, then contributed to the reduction of the increased expenditures of health insurance health care Health insurance health care expenditure: Comparing the increased proportions of health insurance health care expenditures at the CHSs of the two districts between 2012 and 2011 (Table 3.23) showed that the differences are statiscally significant (p<0.05), and all of the increased proportions of Dak To district are less than that of the Kon Ray district (except the health examination fees, medicine cost proportion, and technical-service cost proportion). This is, again, good evidence that the CHSs applying capitation health insurance could better controll the increase of health insurance health care in comparison with the CHSs applying the fee-for-service health insurance payment. The higher increased proportions of health examination fees and the proporiton of technical-service cost at the capitation health insurance CHSs than that at the fee-for-service health insurance is a good sign. It suggests that the CHSs applying the capitation health insurance PM provided more and more health care services. This is totally different with the theory of capitation payment that the health facilities receving capitation fund tend to limit health care provison for the patients The full expenditure of health care service at the CHSs: Compare to the maximum cost of the Circular number 4 of Ministry of Health Ministry of Finance, the average taken back expenditure was only 6.2% (only regular expenditure), much lower that the study conducted by Hoang Van Minh

27 25 (18.9%). If both the investment expenditure and regular expenditure were calculated, the average taken back expenditure is 5.4% (Table 3.35). This is showed that the studied CHSs are experiencing with the lack of fund for health care services. Fees for health care services should be increased in the near future. CONCLUSIONS 1. Situation of fee-for-service payment for health care based on health insurance at some CHSs, The fee-for-service PM for total health examinations at the three CHSs increased by 28.0% in 2012 compared to in The average health examinations and health examination frequency/card were all increased in 2012 compared to Total health insurance-based health examination expenditures increased by 28.0% in 2012 compared to in 2011 at the CHSs using three fee-for-service PM, of which all of the sub-totals increased average expenditure/card in 2012 increased 25.9% compared to in Compare to 2011, the average health examination expenditure per one health examination at the three fee-forservice PM CHSs in 2012 increased at all of the groups, except for the group 4. This conclusion suggests that there were an increase of service provison, utilization, and health insurance health examination expendtures at the CHSs applying fee-for-service PM in 2012 compared to in The effectiveness of health insurance based capitation payment method at some CHSs of the Dak To district

28 26 - The increased proportion of domestic antibiotic, prescriptions having original names of medicines, qne appropriate antibiotics with diagnose at the thee pilot CHSs were 100%, 120.5%, and 11.6%, respectively, higher than that at the three fee-for-service payment CHSs, 98.9%, 4%, and - 1.4%, respectively.

30 28 This conclusion evidenced that the CHSs applying capitation health insurance PM have a clear effectiveness on some health care indicators, service quality, and better control health care expenditure in comparison with the feefor-service payment CHSs, that meet the expectations of stakeholders (social insurance agencies, health care service providers, and health-insured people). However, some results from the professional study such as quality of prescription, improved health examination quality... could be confounded by professional training but not merely the impacts of capitation PM. RECOMMENDATIONS 1. Develop a roadmap and change the health insurance - based fee-for-service PM into health insurance capitation PM as soon as possible at the CHSs. 2. The pilot model of capitation health insurance PM for health care expenditure has been conducted at the 3 CHSs of Dak To district, Kon Tum province which shows as an effective model. Therefore, the model needs to be tested in different socio-economic areas in order to thoroughly assess and apply nationwide as soon as possible. 3. The fees should be adjusted for health care services at the commune level, so appropriate for the situations in different stages. 4. The budget allocation method should be innovated appropriately for CHSs to ensure that the budget will be paid for preventive medicine and public health services.
