DESIGN: Economic evaluation study focusing on employment effect. METHOD: An input–output model was used to estimate the employment‐inducing effect of the new staffing policy. The analysed data of 26,381 beds, of 400 hospitals that are participated in the Integrated Nursing and Care Service scheme were retrieved from the Korean National Health Insurance claims database. RESULTS: The job‐creation effect of the new staffing policy was estimated to be 48.5 persons per USD 1 million expenditure, which means 28,154 persons were employed when USD 580.15 million expenditures was paid to the hospitals by the National Health Insurance Service. In addition, the policy had an employment‐inducing effect which is as high as 3.09~6.07 times higher than that of similar industries and all industries. The shortage of nurses has resulted in nurses' burnout and the deterioration of nursing quality as some nursing services had to be transferred to guardians or private caregivers illegally (Kim et al., 2017) . The 2015 outbreak of the Middle East Respiratory Syndrome in Korea, in particular, raised the issue of restricting resident guardians and visitors to resolve the overcrowding problem at medical institutions (Cho et al., 2016) . The MERS outbreak urged the government to introduce the nurse staffing policy reforms in the form of the "Integrated Nursing and Care Service" (INCS) scheme in 2015 (Kim et al., 2017) . INCS scheme aims to improve the quality of nursing services by enforcing nurse staffing level. It is optional for hospitals to implement this scheme and receive a compensation of approximately 130% of the total labour costs from the national health insurance. In Korea, the number of nursing personnel required in a medical facility is regulated by the Medical Service Act since 1982, with the minimum criterion being the average number of annual inpatients admitted at a particular facility divided by 2.5. However, many medical institutions, including 37% of general hospitals, 71% of small-to medium-sized hospitals and 37% of medical clinics, have reportedly failed to comply with this law (Cho et al., 2016) . The number of active nurses in Korea was 3.8 per 1,000 population in 2018, compared | 2851 KIM et al. with the Organisation for Economic Co-operation and Development (OECD) average of 7.4 per 1,000 population. Further, the number of new nurses supplied per 100,000 population was 35.0 in the same period, compared with the average of 26.5, as reported by the OECD, indicating a shortage in the number of practising nurses employed in the medical field, compared with the supply capacity of nurses (OECD, 2020) . Many studies have analysed the impact of the nurse staffing level on patient outcomes and safety in the United States, Canada and Europe (Aiken et al., 2014; Bowden et al., 2019; Kane et al., 2007; Needleman et al., 2011) , therefore, many countries have begun to implement policies aimed at increasing the number of nurses. This is also the case in Korea, where a number of studies have similarly reported on the relationship between the nurse staffing level and patient outcomes at long-term care and acute care hospitals (Kim et al., 2014; Kim & Lee, 2015) . In 2007, the Korean government upgraded the differentiated scheme for inpatient nursing fees to establish a subtraction grade scheme to induce medical institutions in order to secure more nurses. This scheme classifies nurse staffing levels into grades 1 through 7 and has the National Health Insurance Service (NHIS) pay the differentiated hospitalization fees according to grade, or deduct the fee in the case of grade 7 (Yu & Kim, 2013) . According to Hong and Cho (2017) , 69.8% of tertiary general hospitals, 58.5% of general hospitals and 31.7% of small-to medium-sized hospitals have raised their nurse staffing grades between 2008-2016. However, 9.0% of general hospitals and 33.3% of small-to medium-sized hospitals have lowered theirs, which indicated that the differentiated scheme for small-to medium-sized hospitals are still having difficulties in staffing of nurses. The new nurse staffing policy in a form of INCS adopted a concept similar to the nurse-patient ratios used in the United States based on the maximum number of patients covered by a nurse providing direct nursing services in the wards. The recommended nurse-patient ratio under this new policy is 1:5-1:7 for tertiary general hospitals, 1:7-1:12 for general hospitals and 1:10-1:16 for small-to medium-sized hospitals, and a ratio of 1:20-1:40 for nursing assistants. These new measures induced medical institutions to hire more nurses, as the NHIS pays higher fees when there is a higher nurse-patient ratio (Kim et al., 2017) . As the new staffing policy measures have been established since 2015, the time has come to evaluate the effectiveness of the measures in securing nursing professionals. The national health insurance budget is used to secure an appropriate number of nursing personnel, thus providing high-quality services by nursing professionals. It is also necessary to evaluate the impact of the budget input by NHIS on job creation. However, previous studies have mostly focused on analysing patient outcomes, such as patient satisfaction and patient safety (Jung & Sung, 2018) This study, therefore, aims to measure the economic effect of the new staffing policy, following the application of the nurse-patient ratio as the criterion for nurse staffing level in the INCS scheme. The study analyses the impact of the new personnel policy measures on the nursing personnel market, society and the economy by examining employment creation through an inter-industry analysis. The input-output model in inter-industry analysis assumes that the level of an industry's production increases as input increases in each sector when there are no economies of scale. Thus, it indicates how a change in a sector's production level generates a continuous demand for products in another sector (Motiwalla et al., 2005; San Cristobal & Biezma, 2006) . final demand (Y i ) and total output) (X i ) of industry i. The relationships in such an output structure can be expressed as Equation (2). In this equation, a ij is called the input coefficient and refers to the input or output (a ij = Z ij ∕X j ) of industry i used to produce a unit of output in sector j. M i refers to the import amount vector, which was excluded in this study as this study focuses on measuring the impact in Korea. Meanwhile, R i refers to the amount of waste generated. The equation (1) Equation (I − A) − 1 is called the Leontief inverse matrix or the production inducement coefficient (Bank of Korea, 2019). The input-output matrix developed by the Bank for the specific goods occurs by one unit. The labour inducement coefficient is calculated as the product of the labour coefficient and the production inducement coefficient. The labour coefficient (E i ) is calculated as E i = M i /X i by dividing the labour (M i ) input for the production activity by the total output (X i ) during a specific period and refers to the labour directly consumed for the production of a unit. Therefore, the number of employed persons required to produce Y can be expressed by Equation (3). In this equation, the labour in- This study applied a production inducement coefficient of 1,727 for the health and social service industry in the input-output table. It refers to the direct and indirect outputs to be produced in each industrial sector for one unit of the final demand in the health and social service industry sector in the production inducement coefficient The input-output The input-output table used in this study was previously published In December 2017, a total of 400 hospitals, 647 wards, and 26,381 beds were found to be participating in the INCS scheme. All 43 tertiary general hospitals were participating, and 189 of 301 general hospitals (62.8%) and 168 of 1,466 small-to medium-sized hospitals except for long-term care hospitals (5.6%). were 12,381, including 2,079 (16.8%) in tertiary general hospitals, 7,111 (57.4%) in general hospitals and 3,191 (25.8%) in small-to medium-sized hospitals. In the case of certified nursing assistants, 413 (10.2%), 2,260 (56.1%) and 1,354 (33.6%) were employed, respectively. With the total of 2,167 nursing assistant personnel, 211 (9.7%) were employed in tertiary general hospitals, 949 (43.8%) in general hospitals and 1,007 (46.5%) in small-to medium-sized hospitals, indicating that most worked in small-to medium-sized hospitals ( We estimated the effect of the INCS scheme on employment creation for nursing personnel using the Bank of Korea's input-output model. Since no statistical data on indirectly employed persons was available, the labour coefficient in this study was estimated from the la- (Table 2) . At the end of 2017, the final demand generated for the INCS scheme was USD 580.15 million. Based on the data gathered, the number of jobs created directly or indirectly from the scheme was estimated, and it was found that the annual number for direct labour was 17,321 persons, and indirect labour 12,592 persons, with a total of 29,914. We compared the number of jobs in the health and social service industry with all industries. The total number of staff was 10,501 for health and social services, showing that the INCS scheme was 2.85 times more effective in job creation than the health and social service industry. The number was 6,846 for all businesses, indicating that the INCS scheme was 4.37 times more effective in job creation than all industries (Table 3) . The shortage of nurses is a worldwide problem, and governments have implemented various measures to remedy this, sometimes by recruiting foreign nurses or retaining locals. The Korean government already has a policy of promoting a larger number of new nurses and has implemented a differential nursing fee system to address this problem. Despite this, medical institutions have difficulties recruiting nurses, and additionally, only 63% of general hospitals and 19% of small-to medium-sized hospitals have complied with the legal nursing personnel standard (Cho et al., 2016) . As a result, a new fee incentive that is part of the new policy. This policy incentive is a 10% additional fee payment in consideration of environmental improvement and various administrative expenses for the establishment of the integrated nursing wards. Based on a six-person room in a general hospital, the daily hospitalization fee per patient in such an integrated nursing and care service ward was 23.7% higher than that in a general ward (Kim et al., 2017) . Moreover, if the number of nurses for exclusive night time services accounts for 5% or more of the total number of nurses, 30% is added to the fee payment to compensate for the nursing service quality. Payments for other fees are added differentially according to the nurse-to-patient ratio and the number of patients served by the ward support personnel or nursing aids (Kim et al., 2017) . The Korean government has plans to expand the INCS scheme to more than 100,000 beds by 2022. However, many aspects relating to the scheme need to be addressed and improved before its expansion, such as the high workload of integrated nursing care ward nurses, ambiguous division of roles between nurses and nursing aides, and low compensation compared with the workload. In particular, 79% of nurses in a study responded that, while the INCS scheme was good, it was also a burden on nurses (Kim et al., 2017) . This indicates that the nursing staffing level should be improved since the scheme is expected to increase the intensity and degree of responsibility of nurses. The nurse staffing standard for tertiary general hospitals graded Level 1 in Korea is a nurse-to-patient ratio of 1:7-1:10, whereas that for acute internal surgery wards in Australia is 1:4, and that for California in the United States is 1:5. Hence, it is necessary to strengthen staffing standards in Korea. The nurse-to-patient ratio can affect the number of nurses assigned to each unit according to the severity of the patients' illness and bed turnover. However, the 5:20 ratio in Victoria, Australia is advantageous because it is based on the minimum number of nurses per ward rather than per patient and can increase the nursing personnel staffing level and respond sensitively to the number of patients (Gerdtz & Nelson, 2007) . In other words, although the recommended ratio of four patients per nurse may be changed due to changes in the patients' nursing needs, the ratio of 5:20 must be maintained at each ward. This flexible scheme empowers the nursing manager to give team-based nursing by granting the autonomy of the skill mix at an Enrolled Nurse ratio below 20% as long as the 5:20 ratio is maintained. In Australia, decreased patient waiting times in hospitals, increased number of years of service among nurses, improved hospital economic performance, decreased patient mortality, and decreased nurse burnout have been reported after the reinforcement of the nurse staffing level (Aiken et al., 2002; Duffield et al., 2011) . In California, an increase in the number of nurses by 80,000 between 1999-2007 and a reduction of nurse turnover and vacancy rates to less than 5% has been reported (Jones & Gates, 2007) . With all these factors in mind, it is necessary to improve the working environment of nurses, by improving the ward structure and reinforcing the nurse staffing level. Moreover, a compensation system befitting the increased workload and responsibility compared to general wards should be prepared. This study analysed the macroeconomic effect of the new nurse staffing level after the implementation of the INCS scheme in connection with nurse employment in Korea. According to the inputoutput model, based on the input-output table of the Bank of Korea in 2019, the national financial expenditure of USD one million led to the employment of 48.5 wage workers, including 28.1 nursing staffs through the hospitals and 20.4 wage workers through indirect employment. The scheme was highly effective in job creation, as the job creation effect was 3.09-6.07 times higher than that of similar industries and all industries. The INCS scheme is expected to be fully expanded in the future, and the effect of job creation is therefore expected to expand. In preparation for securing a stable manpower along with an increase in jobs, employers should also improve the working environment. The limitation of this study is that the employment quality aspect was not considered as only the quantitative data of budget and input personnel from the aspect of the employment creation effect was used. Considering that the employment quality of nursing personnel could have affected the results of the subjects, future studies should analyse qualitative aspects of employment, such as employment stability, wage level and workload.
