Effects of vertical integration on the healthcare system in China: a systematic review and meta-analysis.

Vertical integration is one possible way to improve the performance of a healthcare system; however, its effects are inconsistent, and there is a lack of evidence from undeveloped nations. This study aims to systematically review the evidence regarding effects of vertical integration on healthcare systems in China. We searched PubMed, Embase, Cochrane Library, Web of Science, ProQuest Health & Medicine Collection, China Knowledge Resource Integrated Database and Wanfang databases from April 2009 (initiation of new healthcare reform) to May 2021 for randomized controlled trials (RCTs), controlled before and after (CBA) trials, cohort studies and interrupted time series (ITS) trials. Vertical integration in the included studies must involve both primary health institutions and secondary or tertiary hospitals. After screening 3109 records, we ultimately analysed 47 studies, including 27 CBA trials, 18 RCTs and 2 ITS trials. The narrative synthesis shows that all but three studies indicated that vertical integration improved efficiency (utilization and cost of health services), quality of public health services and medical services, health provider-centred outcomes (knowledge and skill) and patient-centred outcomes (patients' clinical outcomes, behaviour and satisfaction). Despite the heterogeneity of vertical integration interventions across different studies, the meta-analysis reveals that it lowered diastolic blood pressure (mean difference (MD) -8.41, 95% confidence interval (CI) -15.18 to -1.65) and systolic blood pressure (MD-5.83, 95% CI -9.25 to -2.40) among hypertension patients, and it lowered HbA1c levels (MD -1.95, 95% CI -2.69 to -1.21), fasting blood glucose levels (MD -1.02, 95% CI -1.53 to -0.50) and 2-hour postprandial blood glucose levels (MD -1.78, 95% CI -2.67 to -0.89). The treatment compliance behaviour was improved for hypertension participants (risk ratio (RR) 1.08, 95% CI 1.04-1.13) and for diabetes patients (RR 1.32, 95% CI 1.08-1.61). Vertical integration in China can improve efficiency, quality of care, health provider-centred outcomes and patient-centred outcomes, but high-quality original studies are highly needed.

The High Risk Factors and Preventive Measures of Percutaneous Nephrolithotomy under the Guidance of B-Ultrasound in the Treatment of Postoperative Renal Calculi.

Objective: The aim of this study is to explore and analyze the high risk factors and preventive measures of percutaneous nephrolithotomy under the guidance of B-ultrasound in the treatment of postoperative renal calculi. Methods: The clinical data of 220 patients with renal calculi admitted to our hospital from 2018 to October 2021 were retrospectively analyzed. All patients were treated with percutaneous nephrolithotomy n = 36) and nonbleeding group (n = 184), comparing the personal data, disease-related data, surgical operation related data of the two groups of patients, single factor and logistic multifactor regression analysis to explore the influence of B-guided percutaneous. Nephrolithotomy is a high-risk factor for postoperative bleeding in patients with kidney stones, and preventive measures are based on high-risk factors. Results: There was no significant difference in the proportion of patients with different genders, whether they had renal surgery, whether they had hypertension, and those with postoperative hepatic insufficiency in the hemorrhagic group and the nonbleeding group (p > 0.05). There was no significant difference in age and body mass index between the bleeding group and the nonbleeding group (p > 0.05). The proportion of patients with diabetes in the bleeding group was higher than that in the nonbleeding group, and the difference between the groups was statistically significant (p < 0.05). Compared with the nonbleeding group, the bleeding group had a higher proportion of patients with calculus diameter ≥2 cm. The proportion of patients with staghorn calculi in the bleeding group was higher than that in the nonbleeding group. The difference between the groups was statistically significant (p < 0.05). There was no significant difference in the proportion of patients with hemorrhage, single or multiple renal stones, and ureteral stones in the hemorrhage group compared with the nonbleeding group (p > 0.05). Compared with the nonbleeding group, the proportion of patients with bleeding in the first stage was higher, and the proportion of patients with operation time >90 min was higher. The difference between the groups was statistically significant (p < 0.05). There was no significant difference in the proportion of patients in the bleeding group compared with the nonbleeding group (p > 0.05). Using Logic multifactorial regression analysis, independent risk factors for bleeding after percutaneous nephrolithotomy under ultrasound-guided bovery include diabetes mellitus, stone diameter, staghorn kidney stones, surgical timing, and staging surgery (p < 0.05). Conclusion: The independent high-risk factors affecting bleeding after percutaneous nephrolithotomy guided by B-ultrasound include diabetes, stone diameter, staghorn type kidney stones, operation time, and staged surgery. According to this, effective preventive measures can effectively reduce the operation and the occurrence of postbleeding.

[Shang Ring versus disposable circumcision suture device in the treatment of phimosis or redundant prepuce].

OBJECTIVE: To compare the clinical efficiency of Shang Ring with that of the disposable circumcision suture device (DCSD) in the treatment of phimosis or redundant prepuce. METHODS: From June 2013 to March 2015, we treated 320 patients with phimosis or redundant prepuce using Shang Ring (n=158) or DCSD (n=162). We compared the operation time, intra-operative blood loss, incision healing time, postoperative complications, postoperative satisfaction, and treatment cost between the two groups of patients. RESULTS: Comparison between the Shang Ring and DCSD groups showed that the operation time was (5.6±1.3) vs (5.4±1.2) min, intra-operative blood loss (1.2±0.8) vs (1.3±0.9) ml, postoperative delayed hemorrhage 3.16% (5/158) vs 4.32% (7/162), incision healing time (16.1±7.2) vs (7.5±2.3) d, wound infection 15.82% (25/158) vs 7.41% (12/162), 1-month postoperative incision edema 29.11% (46/158) vs 9.26% (15/162), overall postoperative satisfaction rate 63.92% (101/158) vs 90.12% (146/162), and treatment cost (1121.2±15.6) vs (2142.6±10.8) RMB ¥. There were statistically significant differences between the two groups in the latter five parameters (P<0.05 ), but not in the first three (P>0.05 ). CONCLUSIONS: The DSCD has an obvious superiority over Shang Ring for its relatively lower complication rate, shorter incision healing time, and better cosmetic appearance.
