Primary care facilities consisting of urban community health centres, rural township hospitals and village clinics provide clinical care, disease prevention activities, health promotion, rehabilitation and family plan- ning. Since the 1980s, market reform in China has brought rapid economic development and privatization of health care. Government funding of health care has fallen, the scheme for rural health insurance has been dismantled and out-of-pocket payments have increased. At the same time, health inequity has increased and hospitals have become the main providers of acute care.1 In an attempt to reverse the deterioration in primary care, the Chinese government launched a systemic health reform in 2009. The aim of the reform was the provision of affordable and equitable health care for all by 2020. As a result of the subsequent substantial infusion of public funding, primary care now occupies a central role in the rebuilding of a public- oriented health system in China. Since 2009, health insurance coverage has expanded rapidly, with the majority of citizens now covered,2 and patient access to primary care facilities has improved.3 In 2011, the national government issued policies that focused on enhancing the public financing of primary care facilities, strengthening the training of general practitioners and a service model based on general practitioner teams. The teams – which consist of a general practitioner and a nurse and, sometimes, a public health specialist – provide clinical and preventive care to enrolled residents.4 Implementation of the national policies began in Shang- hai in 2011 and was expanded to cover Shenzhen in 2012. It is hoped that experience gained from the two megacities will facilitate improvements in the delivery of primary care in the rest of China (a megacity is defined as a metropolitan area with a total population exceeding 10 million people). Community health centres in the two megacities provide similar clinical and public health care according to the national guidelines.5 The clinical services include treatment of common diseases in internal medicine, general surgery, paediatrics, gynaecology, obstetrics and traditional Chinese medical care. The public health services provided in the community health centres are entirely funded by the government and include programmes for the management of diabetes and hypertension, health education, immunization, maternal and child health care, mental health care and communicable disease prevention and reporting.6 Internal migrants make up 80% of Shenzhen’s resi- dents but only 30% of Shanghai’s; less than 5% of Shenzhen’s residents – but 27% of Shanghai’s – are aged at least 60 years.7 A community health centre in Shanghai covers 50 000– 100 000 residents and usually contains between five and eight general practitioner teams.8 In Shenzhen, a community health centre covers 30 000–50 000 residents and contains two or three general practitioner teams.9 The community health centres in Shanghai are fully government-funded and indepen- dent of public hospitals. Any revenues they generate through service provision go directly to the government. Shanghai’s general practitioners are also fully publicly funded and most of them received five years of medical training as undergradu- ates.10 In contrast, Shenzhen’s community health centres are Objective To assess changes in the quality of primary care in two megacities following the introduction of health system reforms in China. Methods We conducted multistage stratified random face-to-face surveys of patients visiting community health centres in Shanghai in 2011 and 2013, and Shenzhen in 2012 and 2013. Quality of primary care was measured using an assessment tool. Difference-in-difference analyses based on multiple linear regressions were used to compare the changes over time, after controlling for potential confounders. Findings Most (2721) of the 3214 participants used a community health centre as their regular source of care and were included in our analyses. The mean total scores for quality of primary care were similar for Shanghai and Shenzhen at baseline. In Shenzhen, the mean total scores for all participants and those on low incomes had worsened by 0.922 (95% CI: 0.629 to 1.215) and 1.203 (95% CI: 0.397 to 2.009), respectively. In Shanghai, however, there were improvements in the mean total scores which included increases in the scores for first-contact utilization, continuity, coordination of information and comprehensiveness. Conclusion The quality of primary care improved in Shanghai but not in Shenzhen. This may be because, in Shanghai, beneficial long-term relationships between patients and general practitioners were supported by capitation payments and the provision of services tailored to the local health priorities. a 2/F School of Public Health, Prince of Wales Hospital, Shatin, New Territories, Hong Kong Special Administrative Region (SAR), China. b School of Public Health, Johns Hopkins University, Baltimore, United States of America. c Shanghai Municipal Commission of Health and Family Planning, Shanghai, China. d Shenzhen Municipal Commission of Health and Family Planning, Shenzhen, China. e Bauhinia Foundation Research Centre, Hong Kong SAR, China. f China Centre for Health Development Studies, Peking University, China.

Public health services in Shenzhen are funded by the municipal government and its general practitioners are hospital employees who have to earn their own salaries through general practice.10 Most of Shenzhen’s general practitioners received only three years of medical training.10 Shanghai promoted the service model based on general practitioner teams by introducing capitation pay- ments for general practitioners and extended benefit packages for residents who enrolled on the teams.11 Although Shenzhen implemented the national policy on the same model, it made no operational changes specifically to promote the model.12 Both megacities promoted the use of community health centres by introducing preferential pric- es and encouraging referrals between the centres and hospitals. We decided to investigate if the health reforms improved the patient- perceived quality of primary care in the two megacities. Methods Participants We measured quality in terms of eight different attributes of primary care, using an internationally recognized as- sessment tool.13–20 Questionnaire-based face-to-face surveys were conducted in two rounds. The first round of the sur- vey was conducted – to coincide with the local introduction of the national policies on primary care – in Novem- ber 2011 in Shanghai and in June 2012 in Shenzhen. The second round was conducted in June 2013 in Shanghai and in August 2013 in Shenzhen. Based on an estimated difference in the mean total primary care score between the two survey rounds of 0.8, with a stan- dard deviation of 5,18 a 95% confidence interval (CI) and a power of 80% – we estimated the minimum sample size in each megacity to be 614. After assuming that 90% of those invited to participate would participate and that 85% of par- ticipants would regard a community health centre as their usual source of care, we aimed to interview 800 indi- viduals in each megacity in each round of the survey. After stratifying each megacity into four geographical areas, we used a computer-generated random sequence to select one study district in each of the areas. Then – again using a computer-generated random sequence – we selected one community health centre in each study district. In each megacity, the two rounds of surveys were conducted in the same four com- munity health centres but potential participants were randomly approached in each round. In each surveyed com- munity health centre – until the number of participants from the centre reached 200 – every fifth care user aged at least 18 years was invited to participate in the survey. Each participant was fully informed of the purpose of the study and provided written informed consent before being interviewed. Evaluating quality The primary care assessment tool was translated into Chinese and vali- dated in a pilot study (available from corresponding author).13,21 This tool measures the patient-perceived qual- ity of primary care in terms of eight attributes: first-contact utilization, first-contact accessibility, continu- ity of care, coordination of services, coordination of information, compre- hensiveness of the available service, comprehensiveness of the provided service and a measure of how well the care was patient-focused (so-called patient-centredness). For each of these attributes, patients are asked how well they agree with a statement that their regular provider of primary care is excellent in terms of the attribute. Us- ing a four-point Likert-type scale, each patient’s level of agreement with each statement is scored from 1 (indicating that the patient definitely does not agree) to 4 (indicating that the patient definitely does agree). The maximum total score is 32. In our study, we re- corded scores and the demographic and socioeconomic characteristics of each participant, their self-reported health status and their diagnosed chronic disease, if any. We classified employment status simply into those who were employed and those who were unemployed. The latter category included participants who had retired. Any household with a monthly income below the value taken as the poverty line in China in 2011 – i.e. 484 United States dollars (US$) – was considered to have a low income whereas any house- hold with a monthly income above the median value for the two megacities in 2011 – i.e. US$ 1613 – was considered to have a high income.22,23 Households with an income between low and high- income level were considered middle income-level. Analysis We used multiple linear regression models to compare the scores for the quality of primary care recorded in the two megacities at baseline and in each megacity during the two survey rounds. We adjusted for several po- tential confounders: sex, age, marital status, migrant status, educational level, employment status, household income, health insurance status, number of visits to the community health centre in the previous 12 months, number of years since the patient’s first visit to the community health centre, self-reported health status and presence of diagnosed chronic disease. To compare the effect of policy changes in the two megacities over time, we applied difference-in- difference analysis using equation (1): 0 1 2 3S ( ) k ij ij ij ij ij k kij ijβ βG β T β G T β X ε= + + + × + +∑ (1) where Sij is the primary care score given by the ith participant in the jth megacity, Gij indicates the megacity, Tij indicates the survey round, the interaction term Gij × Tij indicates the difference in the be- tween-round changes in each megacity, Xkij represents the potential confounder k and β0 and εij represent the intercept and error term in the model, respective- ly. The difference in the between-round changes in the quality scores for each megacity yielded an estimate of β3. We ran three separate regression models – one that included all of the participants, one restricted to those participants who had been diagnosed as having a chronic disease, and one restricted to the partici- pants who came from poor households. All analyses were conducted using SPSS version 19.0 (SPSS Inc., Chicago, United States of America). Ethical approval Ethical approval was obtained from the joint Chinese University of Hong Kong and New Territories East Cluster Clini- cal Research ethics committees (Hong Kong Special Administrative Region, China; reference CRE-2012.441).

Results Participant characteristics In Shanghai, 811 (94%) of the 860 pa- tients invited to participate in the first survey round and 795 (92%) of the 861 invited to participate in the second round completed the questionnaire. The corresponding values for Shenzhen were 806 (85%) of 947 and 802 (84%) of 954, respectively. Of the patients who completed the questionnaire in the first and second rounds, 725 (89%) and 741 (93%) of those in Shanghai and 640 (79%) and 615 (77%) of those in Shenzhen, respectively, said that they regarded the community health centre in which they were recruited as their usual source of care and were therefore included in the subsequent analyses (Table 1). In both megacities, most par- ticipants were female, married and edu- cated to below college level, belonged to a household that was neither poor nor rich and had health insurance (Table 1). Most of the participants in Shanghai were non-migrants older than 59 years who did not have a job. Most had visited the community health centre where they were recruited more than 13 times in the previous 12 months, had first visited that centre more than five years previ- ously and had a chronic disease when they participated in a survey round. In Shenzhen, in contrast, most of the par- ticipants were migrants in employment and younger than 45 years. Compared with those in Shanghai, the participants in Shenzhen were more likely to have a low educational level, come from poor households and lack health insurance but were less likely to have a diagnosed chronic disease and tended to have vis- ited the community health centre where they were recruited less frequently in the previous 12 months (Table 1). Quality scores All participants The mean total quality scores recorded in the first survey round, after adjusting for potential confounders, were similar in the two megacities: 23.18 (standard deviation, SD: 2.52) in Shanghai and 22.77 (SD: 2.75) in Shenzhen (Table 2). In Shanghai, mean total scores increased by 0.712 (95% CI: 0.457 to 0.967) in the second survey round, the scores for first contact, continuity, coordination of information and comprehensive- ness and the second-round total score Ta bl e 2.

In Shenzhen, however, the mean total scores had fallen by 0.922 (95% CI: 0.629 to 1.215) in the second survey round. All except those for first- contact accessibility were lower than the corresponding first-round values. The results of the difference-in-difference analysis indicated that Shanghai expe- rienced much greater improvements in the quality of primary care between the two survey rounds (1.651, 95% CI: 1.266 to 2.037) – at least in terms of first-con- tact utilization, continuity, coordination of information and comprehensiveness – than Shenzhen (Table 2). Participants with chronic diseases At least one diagnosed chronic disease was reported by each of 1178 partici- pants in Shanghai and 237 participants in Shenzhen (Table 3). In the first survey round, there was little difference in the quality scores given by participants with chronic disease in Shanghai (23.18; SD: 2.57) and Shenzhen (23.10; SD: 2.89). In the second round, the score had in- creased to 23.96 (SD: 2.38) in Shanghai. The participants with chronic disease gave scores for all attributes – except coordination of services – that were sig- nificantly higher than the corresponding first-round values. In Shenzhen, the score had fallen to 22.54 (SD: 2.74) and the only score reported in the second round that was significantly different to the corresponding first-round value was the score for comprehensiveness of service availability – which was significantly lower. The results of the difference-in-difference analysis indi- cated that Shanghai’s participants with diagnosed chronic disease experienced much greater improvements in the quality of primary care between the two survey rounds – at least in terms of first-contact utilization, continuity, coordination of information and com- prehensiveness – than their counterparts in Shenzhen (Table 3). Participants from poor households Overall, 389 participants came from poor households (Table 4).

In Shenzhen, there was a more substantial reduction (score: 21.92; SD: 2.65; Table 4). Other observations Income level, migrant status and em- ployment status showed no significant association with the perceived qual- ity of primary care (Table 5). However, participants who had visited their com- munity health centre relatively often in the previous 12 months and those who had first visited their community health centre a relatively long time ago tended to report relatively high scores (Table 5). Discussion We assessed the quality of primary care in two megacities in China, following introduction of health reforms. Between 2011 and 2013, quality of primary care – as perceived by all participants, participants from poor households or participants with diagnosed chronic disease – significantly improved in Shanghai. In Shenzhen, however, the quality of primary care appears to have declined. Compared with the other participants, those who were rich, non-migrant and/or employed did not give markedly higher scores – perhaps because the community health centres in the megacities provide free public health services to all residents. In set- tings where primary care is dominated by private providers, the care received by the rich tends to be of higher quality than that received by the poor.24 Although we investigated changes in primary care quality in the context of the local implementation of national policies, the study design prevented us from demonstrating a causal inference between the policies and the changes that we observed. Our initial survey rounds were conducted shortly after – rather than before – the introduction of policy reform in Shanghai and Shenzhen and we may therefore have missed some of the changes triggered by the reform. Since we only investigated patients at- tending four community health centres in each of the megacities we studied, we should not assume that our findings apply to the whole population. Despite these limitations, it is clear that changes in the quality of care in Ta bl e 4.

Shanghai differed markedly from those observed in Shenzhen. Residents in the catchment areas of community health centres in Shanghai are invited to sign a contract with one of the centre’s teams so that they can receive a package of clinical and preventive care – focused on diabetes and hypertension management, care of the elderly and timely referrals to specialists in large hospitals – free of charge.4 Those who enrol in this package, which supplements the public health package available to all residents, also benefit from a free annual risk as- sessment and prescriptions to cover up to eight weeks of treatment. Up to 2500 enrollees may be enrolled by each team. Most enrollees in Shanghai are elderly individuals with chronic diseases who have health insurance. Teams in Shanghai receive capitation payments equivalent to about US$ 20 per enrollee per year, in addition to fixed salaries. Although 60% of the capitation payment for a team is given upfront, at the start of each year, the remainder is given at the end of the year and only if the team Table 5.

In addition, Shanghai’s community health centres and hospitals are linked by an e-health system that should provide good levels of informa- tion coordination. In Shenzhen, residents are not of- fered any free health services other than those available in the public health package. General practitioners in Shen- zhen’s community health centres receive a fixed salary and a bonus linked with performance but no capitation pay- ments. In Shenzhen, a fixed visit fee was implemented in all community health centres in 2012. Patients with health insurance only have to pay 30% of this fee but other patients – including about half of the megacity’s migrants –have to pay the entire fee out-of-pocket.9,27 In both Shanghai and Shenzhen, scores for the coordination of services fell between the first and second survey rounds – perhaps indicating a general lack of effective collaboration between community health centres and hospitals. Shanghai’s municipal government has fully funded its community health centres, via performance-based pay- ments, since 2006. This has improved the capacity of the human resources and preventive services in the centres.28 Shenzhen’s community health centres are subsidiaries of public hospitals and only marginally funded by the munici- pal government. Although the general practitioners working in the centres are considered to be hospital employees, they receive lower salaries than their counterparts in the hospitals.29 Shen- zhen’s community health centres are also less well staffed and equipped than Shanghai’s. In 2011, for example, there were 3.9 general practitioners per 10 000 population in Shanghai30 but only 2.7 per 10 000 population in Shenzhen. All of Shanghai’s community health centres owned their offices whereas two-thirds of Shenzhen’s had to rent offices.9 Com- pared with other publicly funded com- munity health centres, those managed by hospitals are perceived by patients to offer a lower quality of primary care21 and were shown to have poorer outcomes for treatment of hyperten- sion.31 In Shanghai, primary care has been found to be of higher quality – and more equitable among different income groups – than that in the Hong Kong Special Administrative Region, where public providers are managed under a hospital authority.32 There are several strategies that might facilitate implementation of the national policy to strengthen primary care. First, the capacity of general prac- titioners needs to be strengthened by substantial public investment. Second, the use of capitation payments – which can encourage general practitioners to become health managers and gatekeep- ers33 – needs to be expanded. Third, to make enrolment more attractive to patients, the services provided by teams need to be tailored to the local health priorities – e.g. chronic disease among the elderly in Shanghai and maternal and child health in Shenzhen. Fourth, abolishing the fixed visit fee in Shen- zhen would improve access to primary care for the megacity’s many uninsured migrants. Countries with effective and ef- ficient systems for primary care can achieve relatively good health outcomes at relatively low costs.33 Policies that help to form long-term relationships between patients and general practitioners can improve the quality of primary care. Continuity of care – which promotes mutual understanding and trust be- tween patients and care providers – ap- pears to be a key attribute of a successful system for primary care. ■ Funding: The study was funded by the Research Grants Council of Hong Kong (CUHK 4002-SPPR-10).

Méthodes Nous avons réalisé des enquêtes en face à face aléatoires stratifiées à plusieurs degrés auprès des patients des centres de santé communautaires de Shanghai en 2011 et 2013 et de Shenzhen en 2012 et 2013. La qualité des soins de santé primaires a été mesurée à l’aide d’un outil d’évaluation. Des analyses de l’écart des différences basées sur des régressions linéaires multiples ont été réalisées afin de comparer les changements survenus au fil du temps, après contrôle des facteurs de confusion potentiels. Résultats Sur les 3 214 participants, la majorité (2 721 personnes) a indiqué fréquenter régulièrement le centre de santé communautaire et a été incluse dans notre analyse. Au départ, les scores totaux moyens attribués à la qualité des soins primaires ont été similaires à Shanghai et à Shenzhen. À Shenzhen, les scores totaux moyens attribués par tous les participants et par les participants à faible revenu ont respectivement baissé de 0,922 (IC 95 % : de 0,629 à 1,215) et de 1,203 (IC 95% : de 0,397 à 2,009). À Shanghai, en revanche, les scores totaux moyens ont progressé, notamment avec l’amélioration des scores associés aux critères « utilisation de premier recours », « continuité », « coordination de l’information » et « exhaustivité ». Conclusion La qualité des soins primaires s’est améliorée à Shanghai mais pas à Shenzhen. Cela est peut-être lié au fait qu’à Shanghai, les relations bénéfiques de longue date instaurées entre les patients et les généralistes ont été soutenues par des paiements par capitation et par la fourniture de services adaptés aux priorités de santé locales. Резюме Изменения уровня субъективного восприятия качества первичной медицинской помощи в Шанхае и Шэньчжэне, Китай: метод «разность разностей» Цель Оценка изменения качества первичной медицинской помощи в двух мегаполисах после проведения реформ системы здравоохранения в Китае. Методы Был проведен многоступенчатый стратифицированный индивидуальный опрос выбранных случайным образом пациентов, посещающих общественные медицинские центры в Шанхае (2011 и 2013 гг.) и Шэньчжэне (2012 и 2013 гг.). Качество первичной медицинской помощи определялось с помощью специального инструмента оценки. Для сравнения изменений с течением времени после отсева искажающих факторов использовался метод «разность разностей» на основе множественной линейной регрессии. Результаты Большинство участников (2721 из 3214) регулярно пользуются услугами общественных медицинских центров для получения медицинской помощи, и они были включены в наш анализ. Средняя общая оценка качества первичной медицинской помощи в начале исследования в Шанхае и Шэньчжэне была одинаковой. В Шэньчжэне средняя общая оценка для всех участников и лиц с низкими доходами ухудшилась на 0,922 (95% ДИ: с 0,629 до 1,215) и 1,203 (95% ДИ: с 0,397 до 2,009) соответственно. С другой стороны, в Шанхае отмечались некоторые улучшения средней общей оценки: были получены более высокие оценки в отношении качества обслуживания при первом обращении, непрерывности лечения, организации информационного процесса и комплексности лечения. Вывод Качество первичной медицинской помощи в Шанхае улучшилось, однако в Шэньчжэне этого не произошло. Причиной может быть то, что в Шанхае выгодные долгосрочные отношения между пациентами и врачами общей практики поддерживались за счет подушных платежей и предоставления услуг с учетом местных приоритетов в области здравоохранения.

Resumen Cambios en la calidad percibida en la atención primaria en Shanghai y Shenzhen, China: un análisis de diferencias en diferencias Objetivo Evaluar los cambios en la calidad de la atención primaria en dos megaciudades tras la introducción de las reformas del sistema sanitario en China. Métodos Se llevaron a cabo encuestas cara a cara aleatorias y estratificadas en varias etapas a pacientes que visitaron los centros sanitarios comunitarios de Shanghai en 2011 y 2013 y de Shenzhen en 2012 y 2013. La calidad de la atención primaria se midió utilizando una herramienta de evaluación. Los análisis de diferencias en diferencias basados en regresiones lineales múltiples se utilizaron para comparar los cambios a lo largo del tiempo tras haber controlado los posibles factores de confusión. Resultados La mayoría (2.721) de los 3.214 participantes utilizaban un centro sanitario comunitario como su fuente regular de atención primaria y fueron incluidos en nuestros análisis. Las puntuaciones medias totales de la calidad de la atención primaria eran similares para Shanghai y Shenzhen al inicio del estudio. En Shenzhen, las puntuaciones medias totales de todos los participantes y de aquellos con bajos ingresos había empeorado en un 0,922 (IC del 95%: de 0,629 a 1,215) y un 1,203 (IC del 95: de 0,397 a 2,009), respectivamente. Sin embargo, en Shanghai hubo mejoras en las puntuaciones medias totales, incluidos incrementos en las puntuaciones de la utilización de primer contacto, la continuidad, la coordinación de la información y la exhaustividad. Conclusión La calidad de la atención primaria mejoró en Shanghai pero no en Shenzhen. Esto se puede deber a que en Shanghai, las relaciones beneficiosas a largo plazo entre los pacientes y los médicos generales estaban respaldadas por pagos de capitación y la prestación de servicios adaptados a las prioridades sanitarias locales.
