ABSTRACT

OBJECTIVES: The aims were to study the risk of all-cause mortality associated with chronic obstructive pulmonary disease (COPD) and healthy ageing trajectories (HAT) in three birth cohorts and to determine the moderating role of HAT in the association between COPD and all-cause mortality.

DESIGN: Prospective cohort study.

SETTING: Data from waves 1 to 5 of The Survey of Health, Ageing and Retirement in Europe.

PARTICIPANTS: The total sample was 28 857 community-dwelling individuals aged 50+ years.

MAIN OUTCOME: All-cause mortality associated with COPD and HAT adjusting for covariates. We performed Aalen additive hazards models to explore these associations. Interactions between COPD and HAT were also explored. Analyses were conducted separately in three birth cohorts (>1945, 1936-1945 and ≤1935). Latent class growth analysis was used to classify participants into HAT.

RESULTS: Three parallel HAT were found in the three birth cohorts (‘low’, ‘medium’ and ‘high’ healthy ageing). Participants with COPD had an increased mortality risk, but this effect was no longer significant after adjusting for covariates. The ‘low’ HAT was associated with increased mortality risk in the three subsamples, although this effect was lower after adjustment. The interaction between COPD and HAT was significant only in the ≤1935 birth cohort, indicating that those with COPD and a ‘low’ trajectory had a greater risk of mortality.

CONCLUSIONS: The healthy ageing scale may be a suitable tool to identify patients at higher risk to mitigate disease burden and improve patients’ quality of life.

ABSTRACT

INTRODUCTION: Thyroid dysfunctions (TD) are common medical conditions affecting all global populations. Improved healthcare leading to increasing survival rates and delayed diagnosis rendered significant burden of the disease in the increasing number of patients with TD with comorbid illnesses. Therefore, reducing the burden of TD and improving the quality of care are crucial. Existing poor-quality data that guide evidence-based decisions only provide a fragmented picture of clinical care. The different outcomes across studies assessing the effectiveness of treatments impede our ability to synthesise results for determining the most efficient treatments. This project aims to produce a core outcome set (COS), which embeds the multiple complex dimensions of routine clinical care for the effectiveness studies and clinical care of adult patients with TD.

METHODS AND ANALYSIS: This mixed-method project has two phases. In phase 1, we will identify a list of patient-reported and clinical outcomes through qualitative research and systematic reviews. In phase 2, we will categorise the identified outcomes using the Core Outcome Measures in Effectiveness Trials taxonomy of core domains and the International Classification of Functioning, Disability and Health. We will develop questionnaires from the list of outcomes identified from each domain for the two-round online Delphi exercise, aiming to reach a consensus on the COS. The Delphi process will include patients, carers, researchers and healthcare participants. We will hold an online consensus meeting involving representatives of all key stakeholders to establish the final COS.

ETHICS AND DISSEMINATION: The study has been reviewed and approved by the Ethics Committee for Research Involving Human Subjects, Universiti Putra Malaysia and the Research Ethics Committee, National University of Malaysia. This proposed COS in TD will improve the value of data, facilitate high-quality evidence synthesis and evidence-based decision-making. Furthermore, we will present the results to participants, in peer-reviewed academic journals and conferences.

ABSTRACT

INTRODUCTION: At least 68% of persons with aphasia (PWA) experience reading difficulties. Even though strategy-based interventions are a promising treatment approach for text level reading comprehension deficits in PWA, empirical evidence for their efficacy remains rare. The primary objective of this study is the analysis of the efficacy of a strategy-based intervention on text-level reading comprehension and on reading activities in PWA.

METHODS AND ANALYSIS: In a repeated measures trial, 24 PWA will first participate in a waiting period and then in a strategy-based intervention (14 face-to-face-sessions, 60 min each). We will apply two combinations of strategies to treat either the microstructure or the macrostructure, respectively. Participants will be randomly allocated to two parallel groups that will receive these combinations in interchanged sequences. Assessments will be implemented before and after each period as well as 3 and 6 months after the intervention. The primary outcome measure is text-level reading comprehension measured with a German version of the Test de Compréhension de Textes (TCT-D) and represented by the score TCT-D Total . A non-blinded and a blinded rater will evaluate the primary outcome measure. Secondary outcome measures will address specific reading functions, reading activities and cognitive functions. The sample size was determined with an a priori power analysis. For statistical analysis, we will use contrast analyses within repeated measures analysis of variance models. We expect significant improvements in primary and secondary outcome measures during the intervention as compared with changes during the waiting period.

ETHICS AND DISSEMINATION: This study was approved by the ethics committee of Deutscher Bundesverband für akademische Sprachtherapie und Logopädie (20-10074-KA-MunmErw+Ko). Results and relevant data will be disseminated in peer-reviewed journals, at conferences and on the Open Science Framework.

ABSTRACT

OBJECTIVES: The study aimed to assess the knowledge, attitude and practices (KAP) of HCPs regarding the use of probiotics in different health conditions and to identify various barriers that are associated with their use.

METHODS: A cross-sectional study was conducted on 405 HCPs by using a validated self- administered questionnaire for assessing their KAP towards probiotic use. The study data were analysed using descriptive statistics, χ² test and binary logistic regression (BLR).

RESULTS: Among the 405 participants, only 15.1 % of HCPs had good knowledge, while 15.6% had acceptable practices and 89.1% had a positive attitude towards probiotics. The professional position of HCPs was significantly associated with knowledge (p=0.001) and practice (p=0.001). Among all the HCPs, the pharmacists showed a significant association with good knowledge (p=0.016) and good practices (p=0.024) by using BLR. The lack of knowledge about probiotics was a major barrier to the utilisation of probiotics.

CONCLUSIONS: The poor knowledge and practices regarding the use of probiotics have been seen in the current study. While the participants showed a positive attitude towards the utilisation of probiotics. To transform HCPs’ positive attitude to their practices and to create awareness regarding probiotic use focused training programmes should be initiated by professional health organisations.

ABSTRACT

OBJECTIVES: The study aims to identify high-cost users (HCUs) in the inpatient departments of hospitals in Thailand including their common characteristics, patterns of healthcare utilisation and expenditure compared with low-cost users, and to explore potential factors associated with HCUs so the healthcare system can be prepared to support the HCUs including those who have increased chances of becoming HCUs.

DESIGN AND SETTING: A retrospective secondary data analysis using hospitalisation data from Thailand’s Universal Coverage Scheme (UCS) obtained from the National Health Security Office over a 5-year period from October 2014 to September 2019 (fiscal year 2014-2018).

PARTICIPANTS: Study participants included Thai citizens who had at least one inpatient admission to hospitals under the UCS over the study period.

RESULTS: Over the 5-year period, the top 5% of the hospitalised population (or HCUs) consumed almost 50% of the health expenditure each year. HCUs were more likely to have longer hospital stays, a higher annual number of visits and be admitted to multiple hospitals each year when compared with the low-cost users (the bottom 50% of the hospitalised population). The study further reported that the chance of becoming an HCU is associated with several factors such as increasing age, being male, having a comorbidity and being admitted to hospitals in Bangkok.

CONCLUSIONS: This study confirmed that the HCU phenomenon existed in Thailand, where a majority of inpatient care spending is concentrated in the top 5% of the hospitalised population. The study findings call attention to potential initiatives that can help monitor the magnitude and trend of HCUs and develop policies to prevent HCUs.

ABSTRACT

INTRODUCTION: Paediatric cardiac arrest (PCA), despite its low incidence, has a high mortality. Its management is complex and deviations from guideline recommendations occur frequently. We developed a new interactive tablet app, named PediAppRREST, to support the management of PCA. The app received a good usability evaluation in a previous pilot trial. The aim of the study is to evaluate the effectiveness of the PediAppRREST app in reducing deviations from guideline recommendations in PCA management.

METHODS AND ANALYSIS: This is a multicentre, simulation-based, randomised controlled, three-parallel-arm study. Participants are residents in Paediatric, Emergency Medicine, and Anaesthesiology programmes in Italy. All 105 teams (315 participants) manage the same scenario of in-hospital PCA. Teams are randomised by the study statistician into one of three study arms for the management of the PCA scenario: (1) an intervention group using the PediAppRREST app or (2) a control group Paediatric Advanced Life Support (CtrlPALS+) using the PALS pocket reference card; or (3) a control group (CtrlPALS-) not allowed to use any PALS-related cognitive aid. The primary outcome of the study is the number of deviations (delays and errors) in PCA management from PALS guideline recommendations, according to a novel checklist, named c-DEV15plus. The c-DEV15plus scores will be compared between groups with a one-way analysis of variance model, followed by the Tukey-Kramer multiple comparisons adjustment procedure in case of statistical significance.

ETHICS AND DISSEMINATION: The Ethics Committee of the University Hospital of Padova, coordinating centre of the trial, deemed the project to be a negligible risk study and approved it through an expedited review process. The results of the study will be disseminated in peer-reviewed journals, and at national and international scientific conferences. Based on the study results, the PediAppRREST app will be further refined and will be available for download by institutions/healthcare professionals.

ABSTRACT

STUDY OBJECTIVE: To evaluate the competency of trained health workers in detecting and managing hypertensive disorders of pregnancy during routine antenatal check-ups (ANCs) at primary care facilities in Bangladesh.

STUDY DESIGN AND SETTINGS: Cross-sectional study; conducted in 26 primary care facilities.

OUTCOME MEASURES: Accurate diagnosis of the hypertensive disorders of pregnancy.

METHOD: In total 1560 ANC consultations provided by primary health workers, known as Family Welfare Visitors (FWVs), were observed using a structured checklist between October 2017 and February 2018. All consultations were reassessed by study physicians for validation.

RESULT: Of the ‘true’ cases of gestational hypertension (n=32), pre-eclampsia (n=29) and severe pre-eclampsia (n=16), only 3%, 7% and 25%, respectively, were correctly diagnosed by FWVs. Per cent agreement for the diagnosed cases of any hypertensive disorders of pregnancy was 9% and kappa statistics was 0.50 (p value 0.0125). For identification of any hypertensive disorders by FWVs, sensitivity and positive predictive values were 14% and 50%, respectively. There was a moderate positive correlation between the blood pressure measurements taken by FWVs and study physicians. Only 27% of those who had ‘some protein’ in urine were correctly identified by FWVs. Women diagnosed with any of the hypertensive disorders of pregnancy by FWVs were more likely to be counselled on at least one danger sign of pre-eclampsia (severe headache, blurring of vision and upper abdominal pain) than those without any such diagnosis (41% vs 19%, p value 0.008). All four cases of severe pre-eclampsia diagnosed by FWVs were given a loading dose of intramuscular magnesium sulphate and three among them were referred to a higher facility.

CONCLUSION: The FWVs should be appropriately trained on risk assessment of pregnant women with particular emphasis on accurately assessing the diagnostic criteria of hypertensive disorders of pregnancy and its management.

ABSTRACT

BACKGROUND: Vasectomy occlusive success is defined by the recommendation of ‘clearance’ to stop other contraception, and is elicited by post-vasectomy semen analysis (PVSA). We evaluated how the choice of either a postal or non-postal PVSA submission strategy was associated with compliance to PVSA and effectiveness of vasectomy.

METHODS: We studied vasectomies performed in the UK from 2008 to 2019, reported in annual audits by Association of Surgeons in Primary Care members. We calculated the difference between the two strategies for compliance with PVSA, and early and late vasectomy failure. We determined compliance by adding the numbers of men with early failure and those given clearance. We performed stratified analyses by the number of test guidance for clearance (one-test/two-test) and the study period (2008-2013/2014-2019).

RESULTS: Among 58 900 vasectomised men, 32 708 (56%) and 26 192 (44%) were advised submission by postal and non-postal strategies, respectively. Compliance with postal (79.5%) was significantly greater than with non-postal strategy (59.1%), the difference being 20.4% (95% CI 19.7% to 21.2%). In compliant patients, overall early failure detection was lower with postal (0.73%) than with non-postal (0.94%) strategy (-0.22%, 95% CI -0.41% to -0.04%), but this difference was neither clinically nor statistically significant with one-test guidance in 2014-2019. There was no difference in late failure rates.

CONCLUSIONS: Postal strategy significantly increased compliance to PVSA with similar failure detection rates. This resulted in more individuals receiving clearance or early failure because of the greater percentage of postal samples submitted. Postal strategy warrants inclusion in any future guidelines as a reliable and convenient option.

ABSTRACT

OBJECTIVE: To describe the community context of women who travel to access Mexico City’s public sector abortion programme and identify factors associated with travelling from highly marginalised settings.

METHODS: We used data from the Interrupción Legal de Embarazo (ILE) programme (2016-2019) and identified all abortion clients who travelled from outside Mexico City. We merged in contextual information at the municipality level and used descriptive statistics to describe ILE clients’ individual characteristics and municipalities on several measures of vulnerability. We also compared municipalities that ILE clients travelled from with those where no one travelled from. We used logistic regression to identify factors associated with travelling to access ILE services from highly marginalised versus less marginalised municipalities.

RESULTS: Our sample included 21 629 ILE clients who travelled to Mexico City from 491 municipalities within all 31 states outside Mexico City. The majority of clients travelled from the least marginalised (81.9%) and most populated (over 100 000 inhabitants; 91.3%) municipalities. Most (91.2%) ILE clients came from municipalities with adolescent fertility rates in the bottom three quintiles. Clients with a primary or secondary education (vs high school or more) and those from a municipality with a high adolescent fertility rate (top two quintiles) had higher odds of travelling from a highly marginalised (vs less) municipality (adjusted odds ratio (aOR) 1.46, 95% CI 1.35 to 1.58 and aOR 1.89, 95% CI 1.68 to 2.12, respectively).

CONCLUSION: ILE clients travel from geographically and socioeconomically diverse communities. There is an unmet need for legal abortion across Mexico.

ABSTRACT

Objective: This study aimed to estimate the survival probabilities related to the occurrence of major depressive episodes (MDEs) after the onset of substance use disorders (SUDs) using data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III.

Methods: The Alcohol Use Disorder and Associated Disabilities Interview Schedule-5 was used to diagnose SUD, and psychiatric diagnoses were based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Individuals with incidents of various SUDs with no prior history of MDEs (n = 5,987 with alcohol use disorder [AUD], 1,353 with cannabis use disorder [CUD], 351 with opioid use disorder [OUD], 827 with stimulant use disorder [STUD], and 5,363 with nicotine use disorder [NUD]) were included. The survival probabilities of these groups were compared to those of a control group without an SUD (n = 20,034). Outcome measures included the number of years from the age at SUD onset until MDE occurrence or the time of the interview.

Results: The probabilities of experiencing MDEs after 1 year were 3.56%, 4.80%, 7.78%, 8.46%, and 5.31% for AUD, CUD, OUD, STUD, and NUD, respectively. The groups differed statistically significantly from each other and from the control group (P < .0001). Individuals with AUD and STUD, respectively, had a lower and higher probability of having an MDE compared to those with other SUDs. Young age, family history of depression, anxiety disorder presence, and failure to achieve full remission consistently predicted an MDE for all substances.

Conclusions: The findings highlight that users of all studied substances have an increased probability of having an MDE over the lifespan.
