Timely use of Bakri intrauterine balloon tamponade contributes to the effectiveness in controlling severe postpartum hemorrhage

The aim of the present study was to explore the effectiveness of Bakri intrauterine balloon tamponade (IUBT) in treating severe postpartum hemorrhage (SPPH). A cohort of 198 women with SPPH using IUBT were retrospectively selected. The baseline and maternal outcome characteristics were examined. The results demonstrated that women with SPPH had a high proportion of placenta accrete (53.0%). Bakri IUBT demonstrated a global effectiveness of 84.5% in SPPH treatment, accounting for 82.9% in women with placenta accrete. Compared with women with Bakri failure, women who experienced Bakri success had reduced rates of less use of pre-/post-IUBT intervention, blood transfusion, lower genital tract trauma, estimated blood loss (EBL), and a longer indwelling duration (P<0.05). Logistic regression revealed that the pre-IUBT intervention (OR=3.910; 95% CI: 1.684-9.079; P=0.002) was positively associated with hemostasis success, while lower genital tract trauma was negatively associated with Bakri success (OR=0.091; 95% CI: 0.009-0.894; P=0.040). Moreover, women diagnosed with placenta accrete underwent a greater number of transabdominal placed Bakri IUBT and pre-IUBT interventions than those without placenta accrete (P<0.05). No significant differences were observed in Bakri success, total EBL, pre-/post-IUBT EBL, infused volume of IUBT, IUBT indwelling duration, even the rate of hemostasis, lower genital tract trauma, blood transfusion, post-IUBT intervention, and puerperal fever between women with and without placenta accrete (P>0.05). In conclusion, placenta accrete may be the leading cause of SPPH. Bakri IUBT is an effective and safe measure for SPPH. Pre-IUBT intervention may be predictive of Bakri's success. The timely use of IUBT during labor may mitigate the impact of risk factors identified on PPH.

The Association Between Mild Cognitive Impairment and Medication Non-adherence Among Elderly Patients With Chronic Diseases

BACKGROUND

Medication adherence is essential for optimizing treatment outcomes in elderly patients who frequently contend with multiple chronic diseases requiring pharmacological interventions. Mild cognitive impairment (MCI) is a prevalent cognitive disorder among the elderly population, but its impact on medication adherence among elderly patients is still uncertain. This cross-sectional study aimed to investigate the impact of MCI on medication adherence among elderly patients.

METHODS

A cross-sectional study of 436 elderly patients with common chronic diseases aged 60 years and above was conducted. Medication adherence was measured using the Morisky Medication Adherence Scale-8 (MMAS-8). MCI was screened, and cognitive status was assessed using the Mini-Mental State Examination (MMSE) questionnaire. Multivariate logistic regression analysis was performed to identify independent risk factors of medication non-adherence.

RESULTS

Among these elderly patients, 212 (48.6%) had poor medication compliance, and 181 (41.5%) had MCI. Preliminary analyses showed a significant association between MCI and medication non-adherence among elderly patients (odds ratio (OR)=3.95, 95% confidence interval (95%CI)=2.63-5.92, P<0.001). Multivariate logistic regression analysis showed that MCI was independently associated with the risk of medication non-adherence among elderly patients (adjusted OR=2.64, 95%CI=1.64-4.24, P<0.001). Additionally, adverse drug reaction and poor evaluation of medication effects were also independently associated with medication non-adherence in elderly patients (P<0.05).

CONCLUSION

Findings from this cross-sectional study proved the substantial adverse impact of MCI on medication adherence among elderly patients, and MCI was an independently influential factor of medication non-adherence. Identifying the MCI status early and providing interventions to enhance medication adherence are undoubtedly essential for optimizing healthcare outcomes in elderly patients.

融合器高度对腰椎椎间融合术后结局影响的研究进展

OBJECTIVE

To summarize the effect of cage height on outcomes of lumbar interbody fusion surgery and the importance of the cage height selection.

METHODS

The related literature was widely reviewed to summarize the research progress on the complications caused by inappropriate height of the cage and the methods of selecting cage height.

RESULTS

Inappropriate height of the cage can lead to endplate injury, cage subsidence, internal fixation failure, adjacent segmental degeneration, over-distraction related pain, insufficient indirect decompression, instability of operation segment, poor interbody fusion, poor sequence of spine, and cage displacement. At present, the selection of the cage height is based on the results of the intraoperative model test, which is reliable but high requirements for surgical experience and hard to standardize.

CONCLUSION

The inappropriate height of the cage may have an adverse impact on the postoperative outcome of patients. It is important to develop a selection standard of the cage height by screening the related influential factors.

Changes of factors associated with vaccine hesitancy in Chinese residents: A qualitative study

Introduction

There is an urgent need to address vaccine hesitancy to achieve booster vaccination. This study aimed to reveal the factors associated with vaccine hesitancy (including COVID-19 vaccine) among Chinese residents, address modifications of the factors since the previous year, and propose vaccination rate improvement measures.

Materials and methods

This qualitative return visit study was performed between January and mid-February 2022, following the last interview conducted between February and March 2021. According to an outline designed in advance, 60 Chinese residents from 12 provinces participated in semi-structured interviews.

Results

Vaccine safety was the biggest concern raised by respondents, followed by self-immunity and vaccine effectiveness, eliciting concern since the interview last year. Notably, online media accounted for a more significant portion of suggestion sources than before, and fear of pain was a novel factor affecting vaccine hesitancy. Moreover, unlike other areas, those from provinces with a per capita gross domestic product of 3-5 (RMB 10,000) reported less concern about vaccine price and effectiveness. They tended to seek advice via online media less and were greatly influenced by vaccination policies.

Conclusions

Influential factors of vaccine hesitancy among Chinese residents are changing dynamically. Monitoring these trends is essential for public health measures and higher vaccination levels.

Efficacy and influential factors analysis in hemoporfin-mediated photodynamic therapy in the treatment of port-wine stains: a retrospective analysis

BACKGROUND

Hemoporfin-mediated photodynamic therapy (Hemoporfin-PDT) is a safe and effective treatment modality for port-wine stain (PWS). However, there is still no consensus about the influential factors for the efficacy of the treatment. This study investigated the influential factors associated with the efficacy of Hemoporfin-PDT.

METHODS

We retrospectively analyzed 321 PWS patients who underwent Hemoporfin-PDT at our center from August 2017 to July 2021. The correlation between efficacy versus sex, age, location, type of PWS, treatment numbers, and the lesion size were analyzed.

RESULTS

The numbers of treatment sessions undertaken were associated with the response to therapy, and compared with patients who received one session, patients who received two or more sessions showed a better response (ORadj=2.46, 95%CI, 1.49-4.07; ORadj=6.01, 95%CI, 3.38-10.70, P<0.001). The effect on central face, peripheral face, and neck was superior to the extremity and trunk, respectively (P<0.001). The lesion size smaller than and equal to 25 cm² showed a better effect than those whose lesion size was larger than 64 cm² (ORadj=1.92, 95%CI, 1.03-3.57, P=0.040). However, other variables, including sex and age, were not associated with the efficacy of the treatment.

CONCLUSIONS

Hemoporfin-PDT is an effective and safe treatment for PWS. The number of treatments was a favorable factor for Hemoporfin-PDT, smaller lesion sizes showed a better effect than the larger one, and the location of extremity and trunk was a negative factor.

The Uptake and Vaccination Willingness of COVID-19 Vaccine among Chinese Residents: Web-Based Online Cross-Sectional Study

Objective: To investigate the uptake and vaccination willingness of the COVID-19 vaccine among Chinese residents and analyze the difference and factors that impact vaccination. Methods: The snowball sampling method was used to distribute online questionnaires. Relevant sociodemographic data along with the circumstances of COVID-19 vaccination were collected from the respondents. The χ² test, independent samples t test and binary logistic regression analysis were used to analyze the data. Results: Among 786 respondents, 84.22% had been vaccinated. Over 80% of the vaccinated population have completed all the injections because of supporting the national vaccination policies of China, while the unvaccinated population (23.91%) is mainly due to personal health status. Meanwhile, statistical analysis revealed that the main predictors of not being vaccinated were younger age (3 to 18 years old), personal health status, and lower vaccinated proportion of family members and close friends (p < 0.05). Conclusions: There was a high level of uptake of the COVID-19 vaccine in China, and people who have not been vaccinated generally had a low willingness to vaccinate in the future. Based on our results, it suggested the next work to expand the coverage of the COVID-19 vaccination should be concentrated on targeted publicity and education for people who have not been vaccinated.

Finding flaws in the spatial distribution of health workforce and its influential factors: An empirical analysis based on Chinese provincial panel data, 2010-2019

Background

The maldistributions of the health workforce showed great inconsistency when singly measured by population quantity or geographic area in China. Meanwhile, earlier studies mainly employed traditional econometric approaches to investigate determinants for the health workforce, which ignored spillover effects of influential factors on neighboring regions. Therefore, we aimed to analyze health workforce allocation in China from demographic and geographic perspectives simultaneously and then explore the spatial pattern and determinants for health workforce allocation taking account of the spillover effect.

Methods

The health resource density index (HRDI) equals the geometric mean of health resources per 1,000 persons and per square kilometer. First, the HRDI of licensed physicians (HRDI_P) and registered nurses (HRDI_N) was calculated for descriptive analysis. Then, global and local Moran's I indices were employed to explore the spatial features and aggregation clusters of the health workforce. Finally, four types of independent variables were selected: supportive resources (bed density and government health expenditure), healthcare need (proportion of the elderly population), socioeconomic factors (urbanization rate and GDP per capita), and sociocultural factors (education expenditure per pupil and park green area per capita), and then the spatial panel econometric model was used to assess direct associations and intra-region spillover effects between independent variables and HRDI_P and HRDI_N.

Results

Global Moran's I index of HRDI_P and HRDI_N increased from 0.2136 (P = 0.0070) to 0.2316 (P = 0.0050), and from 0.1645 (P = 0.0120) to 0.2022 (P = 0.0080), respectively. Local Moran's I suggested spatial aggregation clusters of HRDI_P and HRDI_N. For HRDI_P, bed density, government health expenditure, and GDP had significantly positive associations with local HRDI_P, while the proportion of the elderly population and education expenditure showed opposite spillover effects. More precisely, a 1% increase in the proportion of the elderly population would lead to a 0.4098% increase in HRDI_P of neighboring provinces, while a 1% increase in education expenditure leads to a 0.2688% decline in neighboring HRDI_P. For HRDI_N, the urbanization rate, bed density, and government health expenditure exerted significantly positive impacted local HRDI_N. In addition, the spillover effect was more evident in the urbanization rate, with a 1% increase in the urbanization rate relating to 0.9080% growth of HRDI_N of surrounding provinces. Negative spillover effects of education expenditure, government health expenditure, and elderly proportion were observed in neighboring HRDI_N.

Conclusion

There were substantial spatial disparities in health workforce distribution in China; moreover, the health workforce showed positive spatial agglomeration with a strengthening tendency in the last decade. In addition, supportive resources, healthcare needs, and socioeconomic and sociocultural factors would affect the health labor configuration not only in a given province but also in its nearby provinces.

Prevalence and Factors that Influence Potentially Inappropriate Medication Use among Thai Elderly in Primary Care Settings

Background

Older age increases the likelihood of chronic diseases and polypharmacy with the likelihood of potentially inappropriate medications (PIMs) in secondary and tertiary care levels, but in the primary care settings of Thailand there still is a need for more evidence. This study aimed to examine the prevalence of PIM in primary care settings, and to identify factors that influence the use of PIM.

Methods

A cross-sectional retrospective study was conducted in 2017. Eight primary care units from four regions of Thailand were randomly selected. People aged ≥ 60 years in the eight units were studied as participants. The List of Risk Drugs for Thai Elderly (LRDTE) was used as the reference. Multivariate logistic regression was carried out to identify factors that influence.

Results

A total of 4,848 patients aged ≥60 years with 20,671 prescriptions were studied. The mean age was 70.7±8.3 years for males, and 61.2% for females. A little more than 5% (5.1%) had ≥ 3 chronic diseases and 15.0% received polypharmacy (≥5 medications). The prevalence of prescriptions with PIMs was 65.9%. The most frequent PIMs were antidepressants: amitriptyline (28.1%), antihistamines: dimenhydrinate (22.4%) and chlorpheniramine maleate (CPM) (11.2%); and Benzodiazepines: lorazepam (6.5%). Three factors that significantly influenced prescribing of PIMs were polypharmacy (adjusted OR 3.51; 95% CI 2.81-4.32), having ≥3 chronic diseases (adjusted OR 1.44; 95% CI 1.04-2.01), and age ≥75 years (adjusted OR 1.18; 95% CI 1.01-1.38).

Conclusion

More than two-thirds of elderly Thai patients in the primary care settings were prescribed PIMs. Multidisciplinary prescription review and PIM screening in patients aged ≥75 years who have ≥3 chronic diseases or polypharmacy should be implemented in primary care and supportive computerized PIMs alert system is needed.

Influential factors of subacromial impingement syndrome after hook plate fixation for acromioclavicular joint dislocation: A retrospective study

Subacromial impingement syndrome (SIS) after hook plate fixation for acromioclavicular joint (AC) dislocation was the most common complication. However, the researches on its' influential factors were rare. The purpose of this study was to identify the risk factors by analyzing the influencing factors of postoperative SIS and minimize the incidence of SIS in clinical surgery.We retrospectively analyzed the prospectively collected data from 330 consecutive patients with AC joint dislocation between August 2014 and August 2017 at our institute. The SIS was presented as the dependent variable at the last follow-up when the internal fixation was removed. The independent variables included age, gender, body-mass index (BMI), smoking status, alcohol consumption, type of injury, Rockwood Classification, site of injury, operation time, injury-to-surgery, the distance between the hook body and the acromion (DBA), the depth of hook tip (DHT), the distance between the hook plate and the humeral head (DHH), the distance between the acromion and the humeral head (DAH), the hook plate angle (AHP) and acromial shape. Logistic regression analysis was performed to identify independent influential factors of SIS.A total of 312 cases were included and 18 cases were lost. The follow-up rate was 94.5%. In without SIS group, there were 225 cases (123 males and 102 females). In with SIS group, a total of 87 cases were included (56 males and 31 females). The incidence of SIS was 27.8%. DHT (OR = 9.385, 95% CI = 4.883 to 18.040, P < .001) and DBA (OR = 2.444, 95% CI = 1.591 to 3.755, P < .001) were the significant independent risk factor for SIS of AC dislocation treat with hook plate. DAH (OR = 0.597, 95% CI = 0.396 to 0.900, P = .014) and acromial shape with flat and straight (OR = 0.325, 95% CI = 0.135 to 0.785, P = .012) were also independent factors of SIS, but they were all protective.The SIS had a high incidence in fixation of clavicular hook plate for AC dislocation. DHT and DBA were two independent risk factors, DAH and acromial shape with flat and straight were two independent protective factors for SIS. In clinical surgery, we should avoid risk factors to reduce the incidence of SIS.

Which Matters for Medical Utilization Equity under Universal Coverage: Insurance System, Region or SES

BACKGROUND

China has achieved universal coverage, with a higher rate of 95% medical insurance. However, huge inequalities are concealed under universal coverage. This article aims to explore the medical insurance utilization disparities over different insurance schemes, regions, and socioeconomic statuses (SES).

METHODS

This study was based on an open-access dataset in 2010, 2012, 2014, and 2016. A longitudinal analysis and separate logistic models were performed.

RESULTS

Urban Employee Basic Medical Insurance (UEBMI) members had an outstanding advantage in specialist visiting over those on the Urban Resident Basic Medical Insurance Scheme (URBMI) (OR = 0.607, p < 0.001) and New Cooperative Medical System (NCMS) (OR = 0.262, p < 0.001). However, in terms of a doctor visiting if a person is sick, the odds of patients in the NCMS receiving a visit were 55.1% ((OR = 1.551; p < 0.05) higher than those on the UEBMI. Compared with west China, the odds of those in the north-east and east were 2.1% (p > 0.05) and 97.2% (OR = 1.972; p < 0.001) higher for seeking medical treatment if sick, and 10.8% (OR = 0.892; p < 0.01) and 42.7% lower (OR = 0.573; p < 0.001) for a specialist visiting. In terms of SES, for each unit of increase in the Standard International Occupational Prestige Scale (SIOPS), the odds of seeking medical treatment decreased by 4.3% (OR = 0.958; p < 0.05), and the odds of a specialist visiting increased by 17.1% (OR = 1.171; p < 0.001) for each unit of the annual income logarithm.

CONCLUSIONS

NCMS members and residents in west China were in a disadvantage status in terms of access to specialists, though had a higher probability of medical care if sick. SES variables were positively correlated with a specialist visiting consistently. We suggest a further focus on healthcare quality in the west and rural areas.

Factors that Influence Direction Deviation in Freehand Implant Placement

PURPOSE

This retrospective study investigates the accuracy of freehand implant placement and whether the factors of presence of an adjacent tooth, implant quadrant, number of missing teeth, and location of the implant site influence direction and angulation deviations.

MATERIALS AND METHODS

According to specific inclusion and exclusion criteria, a total of 112 implants from 75 partially edentulous patients were recruited for this retrospective study. The implants were inserted using a freehand approach by one experienced clinician (right-handed). The full thickness flap was elevated to expose the alveolar bone in the implant surgery, and the implant crown consisted of an all-ceramic restoration retained by cement. The planned implant position was preoperatively determined using implant planning software. The postoperative implant position was determined by analyzing the alignment after optically scanning the dentition using a specifically designed registration model in Geomagic Studio software. The deviations between the planned and postoperative implant positions were then calculated. The outcomes included direction and angulation deviations between the planned and postoperative implant positions. All data were analyzed by ANOVA, Bonferroni correction, regression analysis, and one-sample t-tests conducted using SPSS.

RESULTS

The 3D deviations between planned and postoperative implant positions were 1.22 ± 0.63 mm at the entrance point, 1.91 ± 1.17 mm at the apical point, and 7.93 ± 5.56° in angulation. The presence of adjacent teeth influenced deviations in the mesiodistal (F = 4.338, p = 0.006) and buccolingual directions (F = 3.017, p = 0.033) at the entrance point and mesiodistal angulation (F = 7.979, p < 0.001). The quadrant influenced deviation in the buccolingual direction at the apical point (F = 6.093, p = 0.001) and buccolingual angulation (F = 6.457, p < 0.001). The number of missing teeth had no effect on deviations of direction and angulation of implants. The location of the implant site affected the deviation in the buccolingual direction at the entrance point (F = 3.096, p = 0.049) and the mesiodistal direction at the apical point (F = 3.724, p = 0.027).

CONCLUSION

The 3D accuracy of freehand-placed implants could be acceptable in clinical situations. The results showed that the presence of an adjacent tooth and the quadrant and the location of the implant site influenced the direction and angulation deviations of the implant position; however, the factor of number of missing teeth did not.

Patient preference and choice of healthcare providers in Shanghai, China: a cross-sectional study

OBJECTIVES

This study aimed to assess patients' healthcare-seeking preferences in mild, chronic, and serious illness; identify influential factors; and examine the reasons underlying patients' healthcare-seeking preference.

DESIGN

A retrospective study.

SETTING

The study was conducted in 14 tertiary hospitals in Shanghai, China.

PARTICIPANTS

Questionnaires were distributed to 1519 patients, and 1114 were completed and returned. All patients participated in the study voluntarily, provided written informed consent, and possessed the ability to complete the questionnaire.

MAIN OUTCOME MEASURES

We measured and compared preferences and choice of healthcare providers in patients if they had experienced mild, chronic, or serious illness.

RESULTS

More than 50% of participants, including those who were >60 years of age, had consulted a doctor more than three times during the preceding year, were single, and were most likely to decide not to seek medical treatment. Community health facilities were the most frequently selected healthcare provider in mild illness. In addition, patients who had no personal preference, did not express a preference for a good environment or first-class medical technology, were concerned about close proximity and short waiting times, and pursued low medical costs were most likely to choose a community health facility. General hospitals were the most frequently selected healthcare provider in chronic and serious illness. In addition, patients who earned higher monthly incomes, did not pursue low medical costs, were not concerned about short waiting times or close proximity, and expressed a preference for first-class medical technology, were most likely to choose general hospitals.

CONCLUSION

Patients' healthcare-seeking preference was influenced mainly by healthcare providers' characteristics, illness severity, and sociodemographic characteristics. These findings indicate that patients' current healthcare-seeking preference was not ideal and requires optimisation.
