Social determinants and participation in fecal occult blood test based colorectal cancer screening: A qualitative systematic review and meta-synthesis.

ISSUE ADDRESSED: Colorectal cancer (CRC) screening through fecal occult blood testing (FOBT) has saved thousands of lives globally with multiple countries adopting comprehensive population wide screening programs. Participation rates in FOBT based CRC screening for the socially and economically disadvantaged remains low. The aim of this systematic review is to explore empirical evidence that will guide targeted interventions to improve participation rates within priority populations. METHODS: PubMed, Embase, Scopus, Cinahl and PsycInfo were systematically searched from inception to 22 June 2022. Eligible studies contained qualitative evidence identifying barriers to FOBT based CRC screening for populations impacted by the social determinants of health. An inductive thematic synthesis approach was applied using grounded theory methodology, to explore descriptive themes and interpret these into higher order analytical constructs and theories. RESULTS: A total of 8,501 publications were identified and screened. A total of 48 studies from 10 countries were eligible for inclusion, representing 2,232 subjects. Coding within included studies resulted in 30 key descriptive themes with a thematic frequency greater than 10%. Coded themes applied to four overarching, interconnected barriers driving inequality for priority populations: social, behavioural, economic and technical/interfaces. SO WHAT?: This study has highlighted the need for stronger patient/provider relationships to mitigate barriers to FOBT screening participation for diverse groups. Findings can assist health professionals and policy makers address the systemic exclusion of priority populations in cancer screening by moving beyond the responsibility of the individual to a focus on addressing the information asymmetry driving low value perceptions.

Cost-effectiveness of taurolidine-citrate in a cohort of patients with intestinal failure receiving home parenteral nutrition.

BACKGROUND: Catheter-related bloodstream infections (CRBSIs) in patients receiving home parenteral nutrition (HPN) for chronic intestinal failure (CIF) are associated with significant morbidity and financial costs. Taurolidine is associated with a reduction in bloodstream infections, with limited information on the cost-effectiveness as the primary prevention. This study aimed to determine the cost-effectiveness of using taurolidine-citrate for the primary prevention of CRBSIs within a quaternary hospital. METHODS: All patients with CIF receiving HPN were identified between January 2015 and November 2022. Data were retrospectively collected regarding patient demographics, HPN use, CRBSI diagnosis, and use of taurolidine-citrate. The direct costs associated with CRBSI-associated admissions and taurolidine-citrate use were obtained from the coding department using a bottom-up approach. An incremental cost-effective analysis was performed, with a time horizon of 4 years, to compare the costs associated with primary and secondary prevention against the outcome of cost per infection avoided. RESULTS: Forty-four patients received HPN within this period. The CRBSI rates were 3.25 infections per 1000 catheter days before the use of taurolidine-citrate and 0.35 infections per 1000 catheter days after taurolidine-citrate use. The incremental cost-effectiveness ratio indicates primary prevention is the weakly dominant intervention, with the base case value of $27.04 per CRBSI avoided. This held with one-way sensitivity analysis. CONCLUSION: Taurolidine-citrate in the primary prevention of CRBSIs in patients with CIF receiving HPN is associated with reduced hospital costs and infection rates.

Interventions for improving clinical outcomes and health-related quality-of-life for people living with skeletal dysplasias: an evidence gap map.

PURPOSE: Skeletal dysplasias are rare genetic disorders that are characterized by abnormal development of bone and cartilage. There are multiple medical and non-medical treatments for specific symptoms of skeletal dysplasias e.g. pain, as well as corrective surgical procedures to improve physical functioning. The aim of this paper was to develop an evidence-gap map of treatment options for skeletal dysplasias, and their impact on patient outcomes. METHODS: We conducted an evidence-gap map to identify the available evidence on the impact of treatment options on people with skeletal dysplasias on clinical outcomes (such as increase in height), and dimensions of health-related quality of life. A structured search strategy was applied to five databases. Two reviewers independently assessed articles for inclusion in two stages: titles and abstracts (stage 1), and full text of studies retained at stage 2. RESULTS: 58 studies fulfilled our inclusion criteria. The included studies covered 12 types of skeletal dysplasia that are non-lethal with severe limb deformities that could result in significant pain and numerous orthopaedic interventions. Most studies reported on the effect of surgical interventions (n = 40, 69%), followed by the effect of treatments on dimensions of health quality-of-life (n = 4, 6.8%) and psychosocial functioning (n = 8, 13.8%). CONCLUSION: Most studies reported on clinical outcomes from surgery for people living with Achondroplasia. Consequently, there are gaps in the literature on the full range of treatment options (including no active treatment), outcomes and the lived experience of people living with other skeletal dysplasias. More research is warranted to examine the impact of treatments on health-related quality-of-life of people living with skeletal dysplasias, including their relatives to enable them to make preference- and valued based decisions about treatment.

Upper GI endoscopy in subjects with positive fecal occult blood test undergoing colonoscopy: systematic review and meta-analysis.

BACKGROUND AND AIMS: The role of gastroscopy to investigate the upper GI (UGI) tract in subjects with a positive fecal occult blood test (FOBT+) result is controversial. We conducted a systematic review and meta-analysis, which aimed to determine the prevalence of UGI lesions in FOBT+ subjects. METHODS: Databases were searched until March 31, 2022 for studies reporting UGI lesions in FOBT+ subjects undergoing colonoscopy and gastroscopy. Pooled prevalence rates of UGI cancers and clinically significant lesions (CSLs; lesions potentially explaining occult blood loss), odds ratio (OR), and 95% confidence intervals (CIs) were calculated. RESULTS: We included 21 studies with 6993 FOBT+ subjects. Pooled prevalence of UGI cancers was .8% (95% CI, .4-1.6) and UGI CSLs was 30.4% (95% CI, 20.7-42.2), and that of colonic cancers and CSLs was 3.3% (95% CI, 1.8-6.0) and 31.9% (95% CI, 23.9-41.1), respectively. There was no significant difference in the prevalence of UGI CSL and UGI cancers in FOBT+ subjects with/without colonic pathology (ORs of 1.2 [95% CI, .9-1.6; P = .137] and 1.6 [95% CI, .5-5.5; P = .460]). Anemia in FOBT+ subjects was associated with UGI cancers (OR, 6.3; 95% CI, 1.3-31.5; P = .025) and UGI CSLs (OR, 4.3; 95% CI, 2.2-8.4; P = .0001). GI symptoms were not associated with UGI CSLs (OR, 1.3; 95% CI, .6-2.8; P = .511). CONCLUSIONS: There is an appreciable prevalence of UGI cancers and other CSLs in FOBT+ subjects. Anemia but not symptoms or colonic pathology are linked to UGI lesions. Although the data suggest that same-day gastroscopy in FOBT+ subjects undergoing colonoscopy yields approximately 25% more malignancies as colonoscopy alone, prospective data are required to determine the cost-efficacy of dual endoscopy as a standard of care for all FOBT+ subjects.

Standardising policy and technology responses in the immediate aftermath of a pandemic: a comparative and conceptual framework.

BACKGROUND: The initial policy response to the COVID-19 pandemic has differed widely across countries. Such variability in government interventions has made it difficult for policymakers and health research systems to compare what has happened and the effectiveness of interventions across nations. Timely information and analysis are crucial to addressing the lag between the pandemic and government responses to implement targeted interventions to alleviate the impact of the pandemic. METHODS: To examine the effect government interventions and technological responses have on epidemiological and economic outcomes, this policy paper proposes a conceptual framework that provides a qualitative taxonomy of government policy directives implemented in the immediate aftermath of a pandemic announcement and before vaccines are implementable. This framework assigns a gradient indicating the intensity and extent of the policy measures and applies the gradient to four countries that share similar institutional features but different COVID-19 experiences: Italy, New Zealand, the United Kingdom and the United States of America. RESULTS: Using the categorisation framework allows qualitative information to be presented, and more specifically the gradient can show the dynamic impact of policy interventions on specific outcomes. We have observed that the policy categorisation described here can be used by decision-makers to examine the impacts of major viral outbreaks such as SARS-CoV-2 on health and economic outcomes over time. The framework allows for a visualisation of the frequency and comparison of dominant policies and provides a conceptual tool to assess how dominant interventions (and innovations) affect different sets of health and non-health related outcomes during the response phase to the pandemic. CONCLUSIONS: Policymakers and health researchers should converge toward an optimal set of policy interventions to minimize the costs of the pandemic (i.e., health and economic), and facilitate coordination across governance levels before effective vaccines are produced. The proposed framework provides a useful tool to direct health research system resources and build a policy benchmark for future viral outbreaks where vaccines are not readily available.

Health System Shock Frameworks Between Theory, Application, and Assessment Comment on "The COVID-19 System Shock Framework: Capturing Health System Innovation During the COVID-19 Pandemic".

The COVID-19 System Shock Framework (CSSF) tested the resilience of service providers throughout the coronavirus disease 2019 (COVID-19) pandemic in Australia. In this commentary, we tackle the topic of the CSSF applicability in less mature health systems and propose elements or dimensions that could be added to provide comprehensive response to future shocks. We acknowledge the fact that information systems, telehealth, and standard operation procedures constitute important pillars of system shock frameworks. However, there are doubts on the applicability of such pillars in middle- and low-income countries where the infrastructure is weaker compared to high-income countries and the digital divide is wider. Moreover, while it provided a paramount solution to deliver health services during the pandemic, the negative impact of telehealth should be addressed. In addition, we propose that CSSF should consider focusing on the continuity of the other medical conditions, which may have been affected due to the mitigation policies. Finally, we propose adding a dimension on the evaluation of CSSF to provide quantifiable and comparable assessment with other providers or systems.

Risk-based decision-making related to preprocedural coronavirus disease 2019 testing in the setting of GI endoscopy: management of risks, evidence, and behavioral health economics.

BACKGROUND AND AIMS: Controversies exist regarding the benefits and most appropriate approach for preprocedural coronavirus disease 2019 (COVID-19) testing (eg, rapid antigen test, polymerase chain reaction, or real-time polymerase chain reaction) for outpatients undergoing diagnostic and therapeutic procedures, such as GI endoscopy, to prevent COVID-19 infections among staff. Guidelines for protecting healthcare workers (HCWs) from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection from outpatient procedures varies across medical professional organizations. This study provides an evidence-based decision support tool for key decision-makers (eg, clinicians) to respond to COVID-19 transmission risks and reduce the effect of personal biases. METHODS: A scoping review was used to identify relevant factors influencing COVID-19 transmission risk relevant for GI endoscopy. From 12 relevant publications, 8 factors were applicable: test sensitivity, prevalence of SARS-CoV-2 in the population, age-adjusted SARS-CoV-2 prevalence in the patient cohort, proportion of asymptomatic patients, risk of transmission from asymptomatic carriers, risk reduction by personal protective equipment (PPE), vaccination rates of HCWs, and risk reduction of SAE by vaccination. The probability of a serious adverse event (SAE), such as workplace-acquired infection resulting in HCW death, under various scenarios with preprocedural testing was determined to inform decision-makers of expected costs of reductions in SAEs. RESULTS: In a setting of high community transmission, without testing and PPE, 117.5 SAEs per million procedures were estimated to occur, and this was reduced to between .079 and 2.35 SAEs per million procedures with the use of PPE and preprocedural testing. When these variables are used and a range of scenarios are tested, the probability of an SAE was low even without testing but was reduced by preprocedural testing. CONCLUSIONS: Under all scenarios tested, preprocedural testing reduced the SAE risk for HCWs regardless of the SARS-CoV-2 variant. Benefits of preprocedural testing are marginal when community transmission is low (eg, below 10 infections a day per 100,000 population). The proposed decision support tool can assist in developing rational preprocedural testing policies.

COVID-19 pandemic in the United Kingdom.

OBJECTIVES: To describe epidemiological data on cases of COVID-19 and the spread of Severe Acute Respiratory Syndrome Coronavirus 2 in the United Kingdom (UK), and the subsequent policy and technological response to the pandemic, including impact on healthcare, business and the economy. METHODS: Epidemiological, business and economic data were extracted from official government sources covering the period 31st January to 13th August 2020; healthcare system data up to end of June 2019. RESULTS: UK-wide COVID-19 cases and deaths were 313,798 and 46,706 respectively (472 cases and 70 deaths per 100,000 population) by 12th August. There were regional variations in England, with London and North West (756 and 666 cases per 100,000 population respectively) disproportionately affected compared with other regions. As of 11th August, 13,618,470 tests had been conducted in the UK. Increased risk of mortality was associated with age (≥60 years), gender (male) and BAME groups. Since onset of the pandemic, emergency department attendance, primary care utilisation and cancer referrals and inpatient/outpatient referrals have declined; emergency ambulance and NHS111 calls increased. Business sectors most impacted are the arts, entertainment and recreation, followed by accommodation and food services. Government interventions aimed at curtailing the business and economic impact have been implemented, but applications for state benefits have increased. CONCLUSIONS: The impact of COVID-19 on the UK population, health system and economy has been profound. More data are needed to implement the optimal policy and technological responses to preventing further spikes in COVID-19 cases, and to inform strategic planning to manage future pandemics.

The COVID-19 pandemic in Greece, Iceland, New Zealand, and Singapore: Health policies and lessons learned.

OBJECTIVES: This paper aims at providing an overview of the COVID-19 situation, health policies, and economic impact in Greece, Iceland, New Zealand, and Singapore. The four countries were chosen due to their ability to contain the spread and mitigate the effects of COVID-19 on their societies. METHODS: We use document analysis based on the available national reports, media announcements, official coronavirus websites and governmental decrees in each of the four countries starting from the 1st of January o the 9th of August announcements. We apply a policy gradient to compare and examine the policies implemented in the four countries. FINDINGS: The four countries have different demographic, epidemiological, socioeconomic profiles but managed to control the pandemic at an early stage in terms of total number of positive cases. The four countries managed to absorb the health system shock and decrease the case fatality ratio of COVID-19. Early interventions were crucial to avoid expected life lost in case of no early lockdown. The pandemic triggered several economic stimulus and relief measures in the four countries; the impact or the economic rebound is yet to be fully observed. CONCLUSIONS: We conclude that early, proactive and strict interventions along with leveraging previous experience on communicable diseases and the evolution of testing strategies are key lessons that can be synthesized from the interventions of the four countries and that could be useful for a potential second wave or similar pandemics.

COVID-19: The need for an Australian economic pandemic response plan.

OBJECTIVES: Pandemics pressure national governments to respond swiftly. Mitigation efforts created an imbalance between population health, capacity of the healthcare system and economic prosperity. Each pandemic arising from a new virus is unknown territory for policy makers, and there is considerable uncertainty of the appropriateness of responses and outcomes. METHODS: A qualitative approach was used to review mixed sources of data including Australian reports, official government publications, and COVID-19 data to discern robust future responses. Publicly available epidemiological and economic data were utilised to provide insight into the impact of the pandemic on Australia's healthcare system and economy. RESULTS: Policies implemented by the Australian Government to mitigate the spread of COVID-19 impacted the healthcare sector and economy. This paper incorporates lessons learned to inform optimal economic preparedness. The rationale for an economic response plan concomitant with the health pandemic plan is explored to guide Australian Government policy makers in ensuring holistic and robust solutions for future pandemics. CONCLUSIONS: In future, an Australian Economic Pandemic Response Plan will aid in health and economic system preparedness, whilst a strong Australian economy and strategic planning will ensure resilience to future pandemics.

How much is too much? The effects of information quantity on crowdfunding performance.

We explore the effects of the quantity of information on the tendency to contribute to crowdfunding campaigns. Using the crowdfunding platform Kickstarter, we analyze the campaign descriptions and the performance of over 70,000 projects. We look empirically at the effect of information quantity (word count) on funding success (as measure by amount raised and number of backers). Within this empirical approach, we test whether an excessive amount of information will affect funding success. To do so, we test for the non-linearity (quadratic) effect of our independent variable (word count) using regression analysis. Consistent with the hypothesis that excess information will negatively affect funds raised and number of contributors, we observe a consistent U-shaped relationship between campaign text length and overall success which suggest that an optimal number of words exists within crowdfunding texts and that going over this point will reduce a project's chance of fundraising success.
