Clinical Impact of "Real World Data" and Blockchain on Public Health: A Scoping Review.

The digitisation of healthcare has allowed a significant rethinking of the previous clinical protocols, improving their interoperability through substantial standardisation. These technological advances have ensured that data are comparable, as they are obtained from 'reliable' and certified processes; however, there are billions of data that are neither structured nor quality-controlled. They are collectively referred to as 'Real World Data' (RWD). Blockchain (BC) is a procedure with specific characteristics and algorithms that ensure that the stored data cannot be tampered with. Nowadays, there is an increasing need to rethink blockchain in a one-health vision, making it more than just a 'repository' of data and information, but rather an active player in the process of data sharing. In this landscape, several scholars have analysed the potential benefits of BC in healthcare, focusing on the sharing and safety of clinical data and its contact tracing applications. There is limited research on this matter; moreover, there is a strategic interest in managing RWD in a reliable and comparable way, despite the lack of knowledge on this topic. Our work aims to analyse systematically the most impacting literature, highlighting the main aspects of BC within the context of the new digital healthcare, and speculating on the unexpressed potential of RWD.

Surrogacy and the Fiction of Medical Necessity.

A number of countries and states prohibit surrogacy except in cases of "medical necessity" or for those with specific medical conditions. Healthcare providers in some countries have similar policies restricting the provision of clinical assistance in surrogacy. This paper argues that surrogacy is never medically necessary in any ordinary understanding of this term. The author aims to show first that surrogacy per se is a socio-legal intervention and not a medical one and, second, that the intervention in question does not treat, prevent, or mitigate any actual or potential harm to health. Legal regulations and healthcare-provider policies of this kind therefore codify a fiction-one which both obscures the socio-legal motivations for surrogacy and inhibits critical examination of those motivations while mobilizing normative connotations of appeals to medical need. The persisting distinction, in law and in moral discourse, between "social" and "medical" surrogacy, is unjustified.

Relationship between patient outcomes and patterns of fragmented cancer care in older adults with gastric cancer: A nationwide cohort study in South Korea.

INTRODUCTION: Fragmented cancer care, defined as receipt of care from multiple hospitals, has been shown to be associated with poor patient outcomes and high expense. However, evidence regarding the effects of hospital choice by patients with cancer on overall survival are lacking. Thus, we investigated the relationship between patterns of fragmented care and five-year mortality in patients with gastric cancer. MATERIALS AND METHODS: Using the Korean National Health Insurance senior cohort of adults aged ≥60 years, we identified patients with gastric cancer who underwent gastrectomy during 2007-2014. We examined the distribution of the study population by five-year mortality, and used Kaplan-Meier survival curves/log-rank test and Cox proportional hazard model to compare five-year mortality with fragmented cancer care. RESULTS: Among the participants, 19.5% died within five years. There were more deaths among patients who received fragmented care, especially those who transferred to smaller hospitals (46.6%) than to larger ones (40.0%). The likelihood of five-year mortality was higher in patients who received fragmented cancer care upon moving from large to small hospitals than those who did not transfer hospitals (hazard ratio, 1.28; 95% confidence interval, 1.10-1.48, P = .001). Moreover, mortality was higher among patients treated in large hospitals or in the capital area for initial treatment, and this association was greater for patients from rural areas. DISCUSSION: Fragmentation of cancer care was associated with reduced survival, and the risk of mortality was higher among patients who moved from large to small hospitals.

Attitudes towards induced abortion among gynecologists in Kurdistan region of Iraq.

BACKGROUND: Unsafe abortion is a major contributor to maternal morbidity and mortality in countries where induced abortion is restricted. In Kurdistan Region of Iraq, induced abortion is strictly forbidden except for life-threatening situations, increasing the risk of seeking unsafe abortions. Attitudes among healthcare professionals who directly encounter cases and consequences of induced abortion can be studied to improve women's access to safe abortion. This study aimed to examine attitudes towards induced abortion among gynecologists in Kurdistan Region of Iraq. METHODS: This cross-sectional facility-based study was conducted in the first quarter of 2022 in Kurdistan Region of Iraq in the cities of Erbil, Sulaymaniyah, and Duhok. Convenient sampling was used to invite 330 gynecologists to participate, with 171 ultimately completing the questionnaire, giving a response rate of 53%. Questionaries using the Taylor and Whitehead abortion attitude scale were sent in person or digitally. The data was then analyzed using Chi-square and Fisher's exact tests to determine the independence of attitudes and associations between attitudes and sociodemographic factors. RESULTS: Among 171 gynecologists, 25% of the gynecologists agreed that induced abortion is unacceptable under any circumstances. Most (71%) disagreed that a woman has the right to choose to have an induced abortion. Around 51% considered induced abortion murder, and 41% agreed that induced abortion goes against all morals. Around 57% disagreed with the legalization of induced abortion, while 43% agreed. Gynecologists who were unmarried (P = 0.025), under the age of 40 (P = 0.044), and with less than 10 years of clinical experience (P = 0.043) were more likely to support the legalization of induced abortion in Kurdistan Region. None of the variables was found to be independently associated with attitudes towards abortion legalization. CONCLUSIONS: Despite some younger gynecologists having more favorable attitudes towards induced abortion, most gynecologists in Kurdistan Region had less favorable views. Most gynecologists were willing to provide post-abortion care regardless of their legal status. We recommend conducting more studies to investigate the consequences of current abortion legislation among women in need of induced abortion in Kurdistan Region of Iraq.

Improving Patient Outcomes Through Effective Hospital Administration: A Comprehensive Review.

This comprehensive review delves into the critical role of effective hospital administration in shaping patient outcomes within the healthcare ecosystem. Exploration of key components, strategies, measurement methodologies, and future trends elucidates the multifaceted nature of hospital administration. Key findings underscore the profound impact of administrative decisions and practices on patient safety, satisfaction, and overall well-being. The review highlights the importance of patient-centred care and interdisciplinary collaboration for enhancing patient outcomes. It emphasises the significance of data-driven measurement and benchmarking, which are instrumental in assessing hospital performance and fostering continuous improvement. Looking ahead, emerging technologies, evolving healthcare policies, and persistent challenges are drivers of change in healthcare administration. However, amidst these transformations, the overarching message remains consistent: effective hospital administration is integral to improving patient outcomes. The conclusion calls for a collective commitment from healthcare leaders and policymakers to prioritise the development of capable administrators, invest in technology, promote value-based care, and address healthcare disparities. This collaborative effort ensures that the pursuit of better patient outcomes remains at the forefront of healthcare administration, ultimately shaping the future of healthcare for generations to come.

Uncertainty, Anxiety and the Post-Pandemic Economic Environment.

There is ample evidence from medical and social sciences that economic crises impact on individual mental health. This makes neuro-psychiatric dynamics and individual mental health, particularly that of entrepreneurs, relevant for economic policy designers. At the same time, economic policies can have an impact on mental health, reducing or increasing economic uncertainty and, consequently, changing the level of anxiety in individuals. The COVID-19 pandemic resulted in a severe economic crisis and a drastic transformation of the European economic environment. However, the severity and impact of this crisis differ from many other economic and financial setbacks of the past, including the one resulting from the 2008 crisis. Moreover, the consequences of the pandemic on mental health will add to the long-term consequences of the 2010s crisis and the effects of the war at Europe's Eastern borders. Together, the three crises may increase economic uncertainty in the post-pandemic World and its impact on mental health. This essay examines the connections between economic uncertainty, anxiety, and mental health. It suggests considering some relevant elements to estimate the impact of economic uncertainty on individual mental health. Also, hypotheses about the consequences of the "three crises shock" on mental health in the post-pandemic World are advanced. Finally, the essay helps anticipate how the EU anti-crisis economic policies may generate needs and opportunities for mental health care in national health systems.

Bridging the "Know-Do" Gaps in Five Non-Communicable Diseases Using a Common Framework Driven by Implementation Science.

According to the United Nations High-Level Meeting 2018, five non-communicable diseases (NCDs) including cardiovascular diseases, chronic respiratory diseases, diabetes mellitus, cancer, and mental health conditions accounted for two-thirds of global deaths. These five NCDs share five common risk factors including tobacco use, unhealthy diets, physical inactivity, alcohol use, and air pollution. Low- and middle-income countries (LMICs) face larger burden of NCDs than high-income countries (HICs), due to differences in ecological, technological, socioeconomic and health system development. Based on high-level evidence albeit mainly from HICs, the burden caused by NCDs can be reduced by affordable medicines and best practices. However, "know-do" gaps, ie, gaps between what we know in science and what we do in practice, has limited the impact of these strategies, especially in LMICs. Implementation science advocates the use of robust methodologies to evaluate sustainable solutions in health, education and social care aimed at informing practice and policies. In this article, physician researchers with expertise in NCDs reviewed the common challenges shared by these five NCDs with different clinical courses. They explained the principles of implementation science and advocated the use of an evidence-based framework to implement solutions focusing on early detection, prevention and empowerment, supplemented by best practices in HICs and LMICs. These successful stories can be used to motivate policymakers, payors, providers, patients and public to co-design frameworks and implement context-relevant, multi-component, evidence-based practices. In pursuit of this goal, we propose partnership, leadership, and access to continuing care as the three pillars in developing roadmaps for addressing the multiple needs during the journey of a person with or at risk of these five NCDs. By transforming the ecosystem, raising awareness and aligning context-relevant practices and policies with ongoing evaluation, it is possible to make healthcare accessible, affordable and sustainable to reduce the burden of these five NCDs.

Infant feeding practices and parental perceptions during the 2022 United States infant formula shortage crisis.

BACKGROUND: In May of 2022, parents living in the United States experienced a dramatic infant formula shortage caused by supply chain issues and the recall of several infant formula products over contamination concerns. METHODS: An anonymous, electronic, cross-sectional survey was designed to understand infant feeding practices, parental experience and perceived support during the crisis. RESULTS: Ninety-nine parents that lived in the U.S. and fulfilled study criteria completed the survey. 66% of respondents were female, and 75% of respondents were recipients of the Special Supplemental Nutrition Program for Women Infant Children (WIC). Parental mean age was 30.0 years, and the mean infant age was 26.8 weeks. The number of individuals that used at least one unsafe infant feeding practice increased from 8% before the infant formula shortage to 48.5% during the shortage (p < 0.001). 79% of parents fed their infants U.S. infant formula brands and 39% of parents fed their infants imported infant formula brands before the shortage which were significantly reduced during the shortage to 27% (p < 0.005) and 11% (p < 0.005), respectively. The percentage of parents that reported infant feeding practices before and during the infant formula shortage significantly increased from 2 to 28% for banked donor milk use (p < 0.005); 5-26% for use of human milk from informal sharing (p < 0.005); and 2-29% for use of watered-down infant formula (p < 0.005). The resources that parents reported as most helpful in navigating the crisis differed by parental sex and WIC recipient status and included other parents, friends, and family; lactation consultants; healthcare providers; and WIC. CONCLUSIONS: Our study found that feeding practices in response to the infant formula shortage may pose health risks to infants including nutrition and food insecurity. These data suggest the need for policy changes within regulatory and the healthcare system to provide families with clinical prenatal and postnatal lactation support, access to pasteurized banked donor milk, and access to more commercially available products.

Adolescent pregnancy: An important issue for paediatricians and primary care providers-A position paper from the European academy of paediatrics.

Adolescent pregnancy and childbearing, remain a widespread health-related problem with potential short and long-term consequences. Comprehensive social, economic, environmental, structural, and cultural factors heavily impact on adolescents' sexual and reproductive health and early pregnancy. Health professionals can play a pivotal role in the prevention of unplanned pregnancy. Improved access to family planning, sexuality education in schools, community-based interventions, and policies contribute greatly to reduce the risk of adolescent pregnancy and the adoption of respectful and responsible sexual behaviour. Additionally, health care professionals can support pregnant adolescents in making decisions under these circumstances and provide adequate health care. This review highlights actions that can guide healthcare professionals in empowering young adolescents to become more aware and capable of making informed decisions about their sexual life, health, and future.

A cross-sectional survey exploring clinician perceptions of a novel Medicaid back pain policy.

OBJECTIVES: Oregon Medicaid (Oregon Health Plan, or OHP) implemented an innovative policy in 2016 that increased coverage of evidence-based non-pharmacologic therapies (NPT, including physical therapy, massage, chiropractic, and acupuncture) while restricting opioids, epidural steroid injections, and surgeries. The objective of this study was to compare the perspectives of clinicians who see back pain patients and can prescribe pharmacologic therapies and/or refer to NPTs and clinicians who directly provide NPT therapies affected by the policy. METHODS: A cross-sectional online survey was administered to Oregon prescribing clinicians and NPT clinicians between December 2019 and February 2020. The survey was completed by 107 prescribing clinicians and 83 NPT clinicians. RESULTS: Prescribing clinicians and NPT clinicians had only moderate levels of familiarity with core elements of the policy. Prescribing clinicians had higher levels of frustration caring for OHP patients with back pain than NPT clinicians (83 vs. 34%, p<0.001) and were less confident in their ability to provide effective care (73 vs. 85%, p = .025). Eighty-six percent of prescribing clinicians and 83% of NPT clinicians thought active NPT treatments were effective; 74 and 70% thought passive NPT treatments were effective. Forty percent of prescribing clinicians and 25% of NPT clinicians (p<0.001) thought medically-light therapies were effective, while 29% of prescribing clinicians and 10% of NPT clinicians thought medically-intensive treatments were effective (p=0.001). Prescribing clinicians thought increased access to NPTs improved outcomes, while opinions were less consistent on the impact of restricting opioid prescribing. CONCLUSIONS: Prescribing clinicians and NPT clinicians had varying perspectives of a Medicaid coverage policy to increase evidence-based back pain care. Understanding these perspectives is important for contextualizing policy effectiveness.

Frequency of Detection of Candida auris Colonization Outside a Highly Endemic Setting: What Is the Optimal Strategy for Screening of Carriage?

Candida auris outbreaks are increasingly frequent worldwide. In our 1000-bed hospital, an endemic transmission of C. auris was established in two of five intensive care units (ICUs). Aims of our study were to describe the occurrence of new cases of C. auris colonization and infection outside the endemic ICUs, in order to add evidence for future policies on screening in patients discharged as negative from an endemic setting, as well as to propose a new algorithm for screening of such high-risk patients. From 26 March 2021 to 26 January 2023, among 392 patients who were diagnosed as colonized or infected with C. auris in our hospital, 84 (21.4%) received the first diagnosis of colonization or infection outside the endemic ICUs. A total of 68 patients out of 84 (81.0%) had a history of prior admission to the endemic ICUs. All were screened and tested negative during their ICU stay with a median time from last screening to discharge of 3 days. In 57/68 (83.8%) of patients, C. auris was detected through screening performed after ICU discharge, and 90% had C. auris colonization detected within 9 days from ICU discharge. In 13 cases (13/57 screened, 22.8%), the first post-ICU discharge screening was negative. In those not screened, candidemia was the most frequent event of the first C. auris detection (6/11 patients not screened). In settings where the transmission of C. auris is limited to certain wards, we suggest screening both at discharge from the endemic ward(s) even in case of a recent negative result, and at least twice after admission to nonendemic settings.

Geriatric Oncology in Portugal: Where We Are and What Comes Next-A Survey of Healthcare Professionals.

In keeping with the trend worldwide, in Portugal, more than 60% of newly diagnosed patients with cancer are aged 65 years or older, which makes older adults the most common population seen in an oncology practice. This study's objectives were to assess geriatric oncology practices in Portugal and investigate medical professionals' current needs and perceptions on the treatment of elderly cancer patients. METHODS: A cross-sectional study was conducted using a web-based survey of healthcare providers treating elderly patients. RESULTS: There were 222 responses: 62.6% of physicians reported the absence of geriatric oncology and/or geriatrics consultations in their institutions, 14.9% had guidelines for the management of older patients with cancer and 4.5% had physicians dedicated to geriatric oncology. The reported use of geriatric assessment tools was 23.4%. Medical oncologists and physicians from medical specialties (p = 0.009) and those practicing in the south of Portugal (p = 0.054) were more likely to use geriatric assessment. Education and training in geriatric oncology was identified by 95.0% of respondents as an unmet need. The inquiries identified that geriatric assessment could be useful to define a therapeutic strategy (85.1%), detect frailty (77.5%), predict toxicity and improve quality of life (73.4%). CONCLUSIONS: There is a paucity of expertise and training in geriatric oncology in Portugal but an increasing perception of the value of geriatric assessment and the demand for education. In the next years, Portugal will progress in this area with the aid of the recently created Geriatric Oncology Working Group.

Lessons for the Implementability and Sustainability of the SURG-Africa Model of Malawi in Colombia Comment on "Improving Access to Surgery Through Surgical Team Mentoring - Policy Lessons From Group Model Building With Local Stakeholders in Malawi".

The development of models that allow improving the quality to achieve person-centered care is a challenge for any health system, especially in low- and middle-income countries, due to the economic difficulties inherent to the countries and to the cost involved in its implementation, which should be assumed by the states, avoiding that the economic burden is assumed by the population, and approaching the goal of universal health coverage. The availability of human talent and efficiency in the use of basic and specialized human talent is a necessity to improve safe access to health services, in this sense, the model proposed by SURG-Africa and whose sustainability in Malawi was evaluated, is an important reference for the establishment and sustainability of these models with other specialties and in other countries. Through this article, the elements of education, care model and financing for the implementation of the strategy in family medicine in the Colombian health system are explored.

Factors Influencing the Desirability, Acceptability, and Adherence of Patients with Diabetes to Telemedicine.

Background and Objectives: Telemedicine solutions have proven their value and efficacy in augmenting diabetes care. In addition to the availability of tools needed to implement telemedicine solutions for patients with diabetes, the patients' desirability, acceptance, and adherence represent major burdens in implementing them. The main aim of this research is to evaluate which factors are influencing the desirability, acceptance, and adherence of patients with diabetes to telemedicine interventions in diabetes care. Materials and Methods: QTelemeDiab, a previously validated instrument for assessing patients' desirability, acceptance, and adherence to telemedicine in diabetes care, was used on 114 enrolled patients with diabetes mellitus, in parallel with demographic, socio-economic, disease history, and psychometric data from all patients. Results: Left-skewed score distributions were observed for the QTelemeDiab total score (median = 166; skewness = −1.738), as well as all its components, thus denoting a high desirability, acceptance, and adherence towards telemedicine use. The presence of severe depression was associated with significant decreases in the QTelemeDiab score (148 vs. 167; p < 0.001), as well as on the desirability sub-score (101 vs. 115; p < 0.001) and adherence sub-score (30 vs. 35; p < 0.001). The presence of severe anxiety was associated with significant decreases in QTelemeDiab score (150 vs. 166), as well as the desirability sub-score (104 vs. 114; p = 0.008) and adherence sub-score (30 vs. 34; p = 0.012). Conclusions: There is a high desirability, acceptance, and adherence to the use of telemedicine interventions in patients with diabetes, both in special and in normal epidemiological settings. The presence of severe anxiety decreases the patient's desirability, acceptance, and adherence, while the presence of severe depression decreases the patient's desirability and adherence to the use of telemedicine interventions in diabetes care.

COVID-19 management: The vaccination drive in India.

Objective: We undertook the study to present a comprehensive overview of COVID-19 related measures, largely centred around the development of vaccination related policies, their implementation and challenges faced in the vaccination drive in India. Methods: A targeted review of literature was conducted to collect relevant data from official government documents, national as well as international databases, media reports and published research articles. The data were summarized to assess Indian government's vaccination campaign and its outcomes as a response to COVID-19 pandemic. Results: The five-point strategy adopted by government of India was "COVID appropriate behaviour, test, track, treat and vaccinate". With respect to vaccination, there have been periodic shifts in the policies in terms of eligible beneficiaries, procurement, and distribution plans, import and export strategy, involvement of private sector and use of technology. The government utilized technology for facilitating vaccination for the beneficiaries and monitoring vaccination coverage. Conclusion: The monopoly of central government in vaccine procurement resulted in bulk orders at low price rates. However, the implementation of liberalized policy led to differential pricing and delayed achievement of set targets. The population preference for free vaccines and low profit margins for the private sector due to price caps resulted in a limited contribution of the dominant private health sector of the country. A wavering pattern was observed in the vaccination coverage, which was related majorly to vaccine availability and hesitancy. The campaign will require consistent monitoring for timely identification of bottlenecks for the lifesaving initiative.

Epidemiological and geographical distribution profile of urban sporotrichosis in the city of São Paulo

Abstract Background Sporotrichosis is the most frequent subcutaneous mycosis in Latin America, where it is considered endemic. At the end of the 20th century, the first cases of zoonotic transmission were described in Rio de Janeiro, triggering an epidemic outbreak that spread to other regions of Brazil. The lack of disease notification omits its real occurrence in the country, which happens in its most populous city, São Paulo. Objective To evaluate the epidemiological aspects of the patients seen at a hospital in São Paulo aiming at establishing the geographic distribution of this disease. Methods This is a retrospective study that analyzed data from medical records of patients with a clinical and laboratory diagnosis of sporotrichosis attended at a tertiary hospital in the city of São Paulo between 2012 and 2020. Results Twenty patients were included. As for zoonotic surveillance, 30% denied contact with an animal, and 70% reported previous contact with a sick cat, with no other animals being mentioned. One case was allochthonous and the others autochthonous, showing a dissemination behavior from a focus in the eastern area of the capital. Study limitations The present study was based on data from only one hospital. Studies that include data from other hospitals and other regions must be carried out to obtain a complete picture of this disease. Conclusions As in other regions of the country, zoonotic sporotrichosis presents itself as an endemic disease with an increase in the number of cases. The findings highlight epidemiological characteristics of great importance so that public health policies can contain disease progression.

Naloxone prescribing practices in the Military Health System before and after policy implementation.

Introduction: Despite public health campaigns, policies, and educational programs, naloxone prescription rates among people receiving opioids remains low. In June 2018, the U.S. Military Health System (MHS) released 2 policies to improve naloxone prescribing. Objectives: The objective of this study was to examine whether the policies resulted in increased naloxone coprescription rates for patients who met the criteria for 1 or more risk indicators (eg, long-term opioid therapy, benzodiazepine coprescription, morphine equivalent daily dose ≥50 mg, and elevated overdose risk score) at the time of opioid dispense. Methods: Prescription and risk indicator data from January 2017 to February 2021 were extracted from the MHS Data Repository. Naloxone coprescription rates from January 2017 to September 2018 were used to forecast prescribing rates from October 2018 to February 2021 overall and across risk indicators. Forecasted rates were compared with actual rates using Bayesian time series analyses. Results: The probability of receiving a naloxone coprescription was higher for patients whose opioid prescriber and pharmacy were both within military treatment facilities vs both within the purchased-care network. Bayesian time series results indicated that the number of patients who met the criteria for any risk indicator decreased throughout the study period. Naloxone prescribing rates increased across the study period from <1% to 20% and did not significantly differ from the forecasted rates across any and each risk indicator (adjusted P values all >0.05). Conclusion: Future analyses are needed to better understand naloxone prescribing practices and the impact of improvements to electronic health records, decision support tools, and policies.

Unmet needs for CKD care: from the general population to the CKD clinics-how many patients are we missing?

INTRODUCTION: Prevalence of chronic kidney disease (CKD) varies around the world. Little is known about the discrepancy between the general population's needs and nephrology care offered. We aimed to contribute to filling this gap and propose a means to infer the number of patients needing follow-up. METHODS: All patients undergoing at least one nephrology consultation in 2019 were enrolled. We used the ratio between CKD Stages 3 and 4 reported in the literature, and considered that only 25-50% of CKD Stage 3 patients have progressive CKD, to hypothesize different scenarios to estimate the number of CKD Stage 3 patients still needing nephrology follow-up. RESULTS: The 1992 CKD patients were followed-up in our centre (56.93% males; age 66.71 ± 18.32 years; 16.82% Stage 1; 14.66% Stage 2; 39.46% Stage 3; 19.88% Stage 4; 7.68% Stage 5). The ratio between Stages 3 and 4 in population studies ranged from 7.72 to 51.29, being 1.98 in our centre. Hypothesizing that we followed-up 100, 70 or 50% of CKD Stage 4 patients, 528-2506 CKD Stage 3 patients in our area would need nephrology follow-up [1885-8946 per million population (p.m.p.)]. Three to 17 additional nephrologists p.m.p. would be necessary to fully cover the need for care. CONCLUSIONS: The number of patients with CKD Stage 3 who would benefit from nephrology care is high. Considering that one patient-year of delay of dialysis could cover a nephrologist's annual salary, interventions aimed to improve the care of advanced CKD may be economically sound.
