Objective:To assess the progress and impact of the China Healthcare Improvement Initiative(CHII) from 2015 to 2020, which aimed at improving patients healthcare experiences.Methods:Five rounds of evaluation surveys were conducted from December 2015 to March 2021 among 136-214 tertiary public hospitals. Structured questionnaires to measure hospital actions and performance, satisfaction of patients and medical staff were designed, and the data were collected by the national and provincial survey teams via onsite inspection, face-to-face/telephone interviews and self-administered cellphone APPs respectively. After data cleaning, the results of five round evaluations were analyzed and compared.Results:The sampled hospitals demonstrated high participation rate in the CHII, and their overall performance turned out to be satisfactory. And the patient healthcare experiences consistently improved over the period of CHII. In contrast to the high satisfaction rate with clinical quality of the sampled hospitals, patients were less satisfied with the non-clinical services such as food and supporting services. The job satisfaction of doctors and nurses experienced mild improvements, while the problems of heavy workload, low salary, and poor health were not effectively solved yet.Conclusions:The implementation of CHII from 2015 to 2020 has played a significant role in promoting patient-centered service models in hospitals, but continuous inputs and coordinated efforts are still required in the future. The improvement of non-clinical services still needs to be addressed to further enhance patient satisfaction. The job satisfaction and well-being of doctors and nurses remain at low level, and effective measures need to be taken to maintain the stability of the medical staff.

Objective:To evaluate the implementation of the China Healthcare Improvement Initiative(CHII)from 2018 to 2020 in 143 tertiary public hospitals in China.Methods:In March 2019 and from January to March in 2021, 143 tertiary public hospitals in 31 provinces of China were investigated using the unified " medical institution questionnaire Ⅰ" and " medical institution Questionnaire Ⅱ" . The data were collected by means of hospital self-report and expert on-site scoring. Descriptive and inferential statistical analysis were used to analyze the data, and the data of two cross-sectional surveys were compared and analyzed.Results:The average score rate of implementing CHII in 143 sample hospitals in 2020 was 88.9%, which was higher than that in 2018(84.4%). The appointment diagnosis and treatment system, clinical pathway management system, day service, smart hospital and humanistic service were significantly improved. In 2020, the average score rate of logistics service, high quality nursing service and clinical pathway management system was higher than 95%, while the average score rate of day service, telemedicine system and medical social work system was lower than 85%. The total score rate of general hospitals was significantly higher than that of specialized hospitals( P<0.001). In 2020, the proportion of hospitals with full marks in 29 secondary indicators(74.4%)was more than 80%, reaching the standard level. Conclusions:The implementation level of CHII in tertiary public hospitals in China has been improved continuously and made significant progress, but some dimensions and indicators need to be further improved.

Objective:To explore the change trend of patients′ recognition of the medical reform effect and medical staff′s occupation and its relationship with medical experience, since the implementation of the China Healthcare Improvement Initiative(CHII), so as to provide reference for exploring the breakthrough point of consolidating the reform effect.Methods:Four indicators of the third-party assessment of patients were selected, which were " I think the medical reform has benefited patients" , " I think the doctor-patient relationship is improving in the past three years" , " I think medical personnel deserve social respect and recognition" , and " I am willing to let my children join the medical profession" . Descriptive and trend analysis were carried out on the survey results, and correlation analysis was carried out between the survey results and patients′ medical experience.Results:Compared with the baseline evaluation results(76.9% and 69.9%for outpatients, 87.3% and 85.6%for inpatients), the patients′ recognition of the sense of medical reform and the improvement of doctor-patient relationship in the fifth evaluation(86.2% and 89.1%for outpatients, 91.4% and 92.6%for inpatients)were significantly improved. The proportion of patients who thought the medical staff was worthy of respect and willing to let their children work in the hospital in the fifth evaluation(97.4%, 79.1%for outpatients, 98.7%, 85.1%for inpatients)were higher than the baseline evaluation results(92.3%, 71.0%for outpatients, 98.1%, 81.6%for inpatients). The above indicators were positively correlated with the patient′s medical experience.Conclusions:Since the implementation of CHII, patients′ recognition of the sense of medical reform and the improvement of doctor-patient relationship has been continuously improved, and patients′ respect and recognition of professional identity of medical personnel is at a high level and continues to improve. Improving medical experience has a positive effect on the improvement of patients′ sense of medical reform.

Objective:To analyze the status quo, trend and influencing factors of patient satisfaction in tertiary maternity and child hospitals in China.Methods:Based on the survey results of five round third-party evaluations of the China Healthcare Improvement Initiative from 2016 to 2021, descriptive trend analysis was conducted on the satisfaction index in tertiary maternity and child hospitals, and the influencing factors of satisfaction were analyzed based on the results of the fifth evaluation.Results:Compared with the first round, the overall patient satisfaction in tertiary maternity and child hospitals in the fifth round was improved(inpatient: from 95.7% to 98.0%; outpatient: from 87.8% to 94.9%). Outpatient satisfaction varied significantly among gender, hospitals of different types, education level, types of treatment, medical insurance and doctors′ titles( P<0.05). Outpatient satisfaction in local hospitals was 1.502 times higher than that in hospitals under the National Health Commission. The satisfaction of referrals was 0.259 times lower than that of patients who were admitted directly. Inpatient satisfaction varied significantly among department, hospitals of different regions, household registration type and whether the admission was delayed due to the COVID-19 epidemic( P<0.05). The satisfaction of inpatients in medical ward and surgical ward was respectively 0.202 and 0.298 times lower than that of inpatients in pediatric ward. Inpatient satisfaction at the central regions was 3.311 times higher than that at the eastern regions. Conclusions:The overall patient satisfaction in tertiary maternity and child hospitals in China is improving. In the future, we should pay more attention to the hospital environment, humanistic care and other non-medical service dimensions with low satisfaction, so as to further improve the medical experience of patients in maternity and child hospitals.

Objective:To investigate the patient satisfaction at tertiary cancer hospitals in China, and explore its determinants.Methods:Based on the fifth third-party evaluation of China Healthcare Improvement Initiative, an inpatient satisfaction survey was conducted from January 2021 to March 2021 in 33 tertiary cancer hospitals in China. Inpatient satisfaction was analyzed, and Chi-square test and binary multivariate logistic regression were run, using the level of overall inpatient satisfaction as a dependent variable.Results:A total of 5 417 inpatients in tertiary cancer hospitals was recruited with 49.8% men. The inpatient at the age of 35-59 accounted for 56.0%, and they were 52.8±13.9 years old. The level of overall inpatient satisfaction was 98.90%. The inpatient satisfaction rates of meal service, waiting time for admission and psychological counseling service provided by hospital were relatively poor, which were 78.75%, 92.40% and 94.11%, respectively. The regression showed that level of overall inpatient satisfaction in the central and western regions(compared with eastern area), with urban and rural residents basic medical insurance or other type(compared with urban employee basic medical insurance), of breast cancer patients(compared with other disease), with unsured postoperative metastasis(compared with non-postoperative metastasis), with low self-rated health score(compared with the score of between 81 and 100)was lower.Conclusions:The inpatients in tertiary cancer hospitals in China is highly satisfied with the care provided. In the future, more attention should be paid to the dimension of lower patient satisfaction, such as diet and psychological counseling.

Objective:To analyze the current level and dynamic change of the salary and income satisfaction rate of doctors in Chinese tertiary public hospitals in recent years.Methods:In January 2018, March 2019 and March 2021, the project team of " the third party evaluation of the China Healthcare Improvement Initiative" conducted a questionnaire survey among doctors of 136 tertiary public hospitals in 31 provinces. The first-line clinicians were investigated by stratified sampling method. The salary level and satisfaction of doctors were investigated by questionnaire. Chi square test was used for comparison between groups.Results:The sample size of the three surveys was 20 786, 23 289 and 22 836 respectively. The median value of doctors′ actual income after tax in 2017, 2018 and 2020 was 100 800 yuan, 120 000 yuan, 150 000 yuan respectively, and the median expected annual income after tax was 196 000 yuan, 250 000 yuan and 250 000 yuan. The proportion of doctors satisfied with the current income was 16.5%, 17.8% and 26.9% respectively. The salary and satisfaction rate of doctors had an upward trend, but the overall level was still low.Conclusions:In recent years, the salary of doctors in tertiary public hospitals in China has been improved to a certain extent, but on the whole, it is at a low level, and there is still much room for improvement. In the future, the government needs to improve the hospital salary system and increase the salary of doctors continuously, especially needs to pay attention to the doctors with high education level and intermediate titles.

Objective:To analyze the salary level, change trend and salary satisfaction of nurses in tertiary public hospitals in China.Methods:The data was derived from three round third-party evaluation of the China Healthcare Improvement Initiative at 136 tertiary public hospitals from December 2017 to January 2018, March 2019 and January to March 2021. The self-reported salary, expected salary and salary satisfaction rate of nurses were analyzed.Results:The sample sizes of the three evaluations were 27 575, 27 568 and 25 197, representing the salary situation in 2017, 2018 and 2020 respectively. In 2017, 2018 and 2020, the actual average annual salary of nurses was 81 600 yuan, 100 000 yuan and 110 000 yuan respectively, the expected average annual salary was 140 000 yuan, 160 000 yuan and 160 000 yuan respectively, and the ratio of expected salary to actual salary was 1.72, 1.60 and 1.45 respectively. In 2017, 2018 and 2020, the proportion of nurses satisfied with their current income was 34.0%, 33.7% and 43.6% respectively. In 2020, nurses in the eastern region, other specialized hospitals, senior professional titles and graduate degrees had highest annual salary.Conclusions:The salary level and satisfaction rate of nurses in tertiary public hospitals in China show a slow growth trend, and the gap between actual salary and expected salary is gradually narrowing.

Objective:To understand the changes in the practice environment from the perspective of doctors in 136 tertiary public hospitals, and to provide evidence for formulating strategies and measures to improve the practice environment of doctors.Methods:The data was collected from five rounds of China Healthcare Improvement Evaluation Survey from December 2015 to March 2021. The sample size was 17 945, 19 774, 20 786, 23 289, and 22 836, with a total of 104 630. The self-designed questionnaire on four dimensions of doctor-patient relationship, workload, administrative logistics support and professional identity was performed.Results:From the 1st to the 5th survey, the approval ratio of " the administrative and logistics department of this hospital is highly efficient" showed the characteristics of " U-shaped distribution" , and the approval ratio of " approve or encourage children to continue to engage in medical work" increased from 13.38% to 23.91%.From the 2nd to the 5th survey, the percentage of doctors who experienced doctor-patient disputes dropped from 28.96% to 23.20%, and the percentage of doctors agreeing that the relationship between doctors and patients in this hospital was improving continued to increase from 33.20% to 60.45%.From the 3rd to the 5th survey, the proportion of doctors experiencing medical troubles dropped from 15.10% to 14.19%, and the recognition rate of " the cafeteria of this hospital provided medical staff with nutritious and delicious meals" increased from 36.25% to 47.52%, and the approval proportion of " my current work load is heavy" dropped from 61.55% to 45.24%. The results of the 5th survey showed that there were significant differences in the approval ratios of each dimension in different genders, job titles and hospital types( P<0.001). Conclusions:From the perspective of doctor-patient relationship, workload, administrative logistics support, and professional identity, the improvement of doctors′ practice environment is still insufficient. Hospital administrators should continue to focus on the improvement of the doctor-patient relationship, and take necessary measures to reduce doctors′ workload and improve doctors′ professional identity.
