The association between primary care quality and healthcare utilisation, costs and outcomes for people with serious mental illness: retrospective observational study

Background Serious mental illness (SMI), including schizophrenia, bipolar disorder and other psychoses, is linked with high disease burden, poor outcomes, high treatment costs and lower life expectancy. In the UK, most people with SMI are treated in primary care by general practitioners (GPs), who are financially incentivised to meet quality targets for patients with chronic conditions, including SMI, under the Quality and Outcomes Framework (QOF). The QOF, however, omits important aspects of quality. Objective(s) We examined whether better quality of primary care for people with SMI improved a range of outcomes. Design and setting We used administrative data from English primary care practices that contribute to the Clinical Practice Research Datalink GOLD database, linked to Hospital Episode Statistics, Accident & Emergency (A&E) attendances, Office for National Statistics mortality data, and community mental health records in the Mental Health Minimum Dataset. We used survival analysis to estimate whether selected quality indicators affect the time until patients experience an outcome. Participants Four cohorts of people with SMI depending on the outcomes examined and inclusion criteria. Interventions Quality of care was measured with: i) QOF indicators: care plans and annual physical reviews ;and ii) non-QOF indicators identified through a systematic review (antipsychotic polypharmacy and continuity of care provided by GPs). Main outcome measures Several outcomes were examined: emergency admissions for i) SMI and ii) ambulatory care sensitive conditions (ACSCs); iii) all unplanned admissions; iv) A&E attendances; v) mortality; vi) re-entry into specialist mental health services; vii) costs attributed to primary, secondary and community mental healthcare. Results Care plans were associated with lower risk of A&E attendance (Hazard ratio (HR) 0.74, 95%CI 0.69-0.80), SMI admission (HR 0.67, 95%CI 0.59-0.75), ACSC admission (HR 0.73, 95%CI 0.64-0.83), and lower overall healthcare (£53), primary care (£9), hospital (£26), and mental healthcare costs (£12). Annual reviews were associated with reduced risk of A&E attendance (HR 0.80, 95%CI 0.76-0.85), SMI admission (HR 0.75, 95%CI 0.67-0.84), ACSC admission (HR 0.76, 95%CI 0.67-0.87), and lower overall healthcare (£34), primary care (£9), and mental healthcare costs (£30). Higher GP continuity was associated with lower risk of A&E presentation (HR 0.89, 95%CI 0.83-0.97), ACSC admission (HR 0.77, 95%CI 0.65-0.92), but not SMI admission. High continuity was associated with lower primary care costs (£3). Antipsychotic polypharmacy was not statistically significantly associated with the risk of unplanned admission, death or A&E presentation. None of the quality measures were statistically significantly associated with risk of re-entry into specialist mental healthcare. Limitations There is risk of bias from unobserved factors. To mitigate this, we controlled for observed patient characteristics at baseline and adjusted for the influence of time-invariant unobserved patient differences. Conclusions Better performance on QOF measures and continuity of care are associated with better outcomes and lower resource utilisation and could generate moderate cost savings. Future work Future research should examine the impact of primary care quality on measures that capture broader aspects of health and functioning

Identifying primary care indicators for people with serious mental illness : a systematic review

Background – Serious mental illness (SMI) – which comprises long term conditions such as schizophrenia, bipolar disorder and other psychoses – has enormous costs for both patients and society. In many countries, people with SMI are treated solely in primary care, and have particular needs for physical care. Aim - The objective of this study was to review systematically the literature to create a list of quality indicators relevant to patients with SMI which could be captured using routine data, and which could be used to monitor or incentivise better quality primary care. Design and setting – A systematic literature review, combined with a search of quality indicator databases and guidelines. Methods – We assessed whether indicators could be measured from routine data and the quality of the evidence. Results – 1,847 papers and quality indicator databases were identified, 27 were included, from which 59 quality indicators were identified, covering six domains. Of the 59 indicators, 52 could be assessed using routine data. The evidence base underpinning these indicators was relatively weak, and was primarily based on expert opinion rather than trial evidence. Conclusions – With appropriate adaptation for different contexts, and in line with relative responsibilities of primary and secondary care, use of the quality indicators has the potential to improve care and to improve the physical and mental health of people with SMI. However, before the indicators can be used to monitor or incentivise primary care quality, more robust links need to be established with improved patient outcomes

Impact of family practice continuity of care on unplanned hospital use for people with serious mental illness

Objective: To investigate whether continuity of care in family practice reduces unplanned hospital use for people with serious mental illness (SMI). Data Sources Linked administrative data on family practice and hospital utilization by people with SMI in England, 2007-2014. Study Design: This observational cohort study used discrete-time survival analysis to investigate the relationship between continuity of care in family practice and unplanned hospital use: emergency department (ED) presentations, and unplanned admissions for SMI and ambulatory care-sensitive conditions (ACSC). The analysis distinguishes between relational continuity and management/ informational continuity (as captured by care plans) and accounts for unobserved confounding by examining deviation from long-term averages. Data Collection/Extraction Methods: Individual-level family practice administrative data linked to hospital administrative data. Principal Findings: Higher relational continuity was associated with 8-11 percent lower risk of ED presentation and 23-27 percent lower risk of ACSC admissions. Care plans were associated with 29 percent lower risk of ED presentation, 39 percent lower risk of SMI admissions, and 32 percent lower risk of ACSC admissions. Conclusions: Family practice continuity of care can reduce unplanned hospital use for physical and mental health of people with SMI

Net1 and Myeov: computationally identified mediators of gastric cancer

Gastric adenocarcinoma (GA) is a significant cause of mortality worldwide. The molecular mechanisms of GA remain poorly characterised. Our aim was to characterise the functional activity of the computationally identified genes, NET 1 and MYEOV in GA. Digital Differential Display was used to identify genes altered expression in GA-derived EST libraries. mRNA levels of a subset of genes were quantitated by qPCR in a panel of cell lines and tumour tissue. The effect of pro- and anti-inflammatory stimuli on gene expression was investigated. Cell proliferation and invasion were measured using in an in-vitro GA model following inhibition of expression using siRNA. In all, 23 genes not previously reported in association with GA were identified. Two genes, Net1 and Myeov, were selected for further analysis and increased expression was detected in GA tissue compared to paired normal tissue using quantitative PCR. siRNA-mediated downregulation of Net1 and Myeov resulted in decreased proliferation and invasion of gastric cancer cells in vitro. These functional studies highlight a putative role for NET1 and Myeov in the development and progression of gastric cancer. These genes may provide important targets for intervention in GA, evidenced by their role in promoting invasion and proliferation, key phenotypic hallmarks of cancer cells

Effect of Hydrocortisone on Mortality and Organ Support in Patients With Severe COVID-19: The REMAP-CAP COVID-19 Corticosteroid Domain Randomized Clinical Trial.

Importance: Evidence regarding corticosteroid use for severe coronavirus disease 2019 (COVID-19) is limited. Objective: To determine whether hydrocortisone improves outcome for patients with severe COVID-19. Design, Setting, and Participants: An ongoing adaptive platform trial testing multiple interventions within multiple therapeutic domains, for example, antiviral agents, corticosteroids, or immunoglobulin. Between March 9 and June 17, 2020, 614 adult patients with suspected or confirmed COVID-19 were enrolled and randomized within at least 1 domain following admission to an intensive care unit (ICU) for respiratory or cardiovascular organ support at 121 sites in 8 countries. Of these, 403 were randomized to open-label interventions within the corticosteroid domain. The domain was halted after results from another trial were released. Follow-up ended August 12, 2020. Interventions: The corticosteroid domain randomized participants to a fixed 7-day course of intravenous hydrocortisone (50 mg or 100 mg every 6 hours) (n = 143), a shock-dependent course (50 mg every 6 hours when shock was clinically evident) (n = 152), or no hydrocortisone (n = 108). Main Outcomes and Measures: The primary end point was organ support-free days (days alive and free of ICU-based respiratory or cardiovascular support) within 21 days, where patients who died were assigned -1 day. The primary analysis was a bayesian cumulative logistic model that included all patients enrolled with severe COVID-19, adjusting for age, sex, site, region, time, assignment to interventions within other domains, and domain and intervention eligibility. Superiority was defined as the posterior probability of an odds ratio greater than 1 (threshold for trial conclusion of superiority >99%). Results: After excluding 19 participants who withdrew consent, there were 384 patients (mean age, 60 years; 29% female) randomized to the fixed-dose (n = 137), shock-dependent (n = 146), and no (n = 101) hydrocortisone groups; 379 (99%) completed the study and were included in the analysis. The mean age for the 3 groups ranged between 59.5 and 60.4 years; most patients were male (range, 70.6%-71.5%); mean body mass index ranged between 29.7 and 30.9; and patients receiving mechanical ventilation ranged between 50.0% and 63.5%. For the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively, the median organ support-free days were 0 (IQR, -1 to 15), 0 (IQR, -1 to 13), and 0 (-1 to 11) days (composed of 30%, 26%, and 33% mortality rates and 11.5, 9.5, and 6 median organ support-free days among survivors). The median adjusted odds ratio and bayesian probability of superiority were 1.43 (95% credible interval, 0.91-2.27) and 93% for fixed-dose hydrocortisone, respectively, and were 1.22 (95% credible interval, 0.76-1.94) and 80% for shock-dependent hydrocortisone compared with no hydrocortisone. Serious adverse events were reported in 4 (3%), 5 (3%), and 1 (1%) patients in the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively. Conclusions and Relevance: Among patients with severe COVID-19, treatment with a 7-day fixed-dose course of hydrocortisone or shock-dependent dosing of hydrocortisone, compared with no hydrocortisone, resulted in 93% and 80% probabilities of superiority with regard to the odds of improvement in organ support-free days within 21 days. However, the trial was stopped early and no treatment strategy met prespecified criteria for statistical superiority, precluding definitive conclusions.

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

A guide to urban forest plans

This guide was written to assist local governments and tree advocacy groups in understanding what to request and what should be expected when undertaking a planning process for their urban forest. While this guide was written for South Carolina, it can be applied universally. This guide came about following GIC’s review of 100 cities and towns in South Carolina and research into other management plans from multiple U.S. cities. Before embarking on an urban forestry plan, reference this guide to determine the type of plan to pursue and the steps to get there

Polymeric Photonic Crystal Fibers for Textile Tracing and Sorting

Circular supply chains require more accurate product labeling and traceability. In the apparel industry, product life cycle management is hampered in part by inaccurate, poorly readable, and detachable standard care labels. Instead, this article seeks to enable a labeling system capable of being integrated into the fabric itself, intrinsically recyclable, low-cost, encodes information, and allows rapid readout after years of normal use. In this work, all-polymer photonic crystals are designed and then fabricated by thermal drawing with >100 layers having sub-micrometer individual thickness and low refractive index contrast (Δn = 0.1). The fibers exhibit reflectance features in the 1–5.5 µm wavelength range, characterized using insitu Fourier transform infrared spectroscopy. Drawn photonic fibers are then woven into fabrics, characterized by near-infrared spectroscopy and short-wave infrared imaging, techniques commonly used in industrial facilities for sorting materials. The fibers’ optical design also enables the use of overtone peaks to avoid overlap with parasitic molecular absorption, substantially improving the signal-to-noise ratio (and therefore ease and speed) of readout. The ability to produce kilometers of fiber that are compatible with existing textile manufacturing processes, coupled with low input material cost, make these a potential market-viable improvement over the standard care label.Over 85% of textiles currently end up in landfills, despite a recent study indicating 74% of low-value, post-consumer textiles could be recovered via fiber-to-fiber recycling. A key challenge in implementing fiber-to-fiber recycling is feedstock ambiguity, and in this work, a polymeric photonic tracer fiber is proposed as a method to enable more efficient life cycle tracing and sorting.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/176058/1/admt202201099_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/176058/2/admt202201099.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/176058/3/admt202201099-sup-0001-SuppMat.pd
