Linking communities and health facilities to improve child health in low resource settings: a systematic review

Community-facility linkage interventions are gaining popularity as a way to improve community health in low-income settings. Their aim is to create/strengthen a relationship between community members and local healthcare providers. Representatives from both groups can address health issues together, overcome trust problems, potentially leading to participants' empowerment to be responsible for their own health. This can be achieved via different approaches. We conducted a systematic literature review to explore how this type of intervention has been implemented in rural and low or lower-middle income countries, its various features and how/if it has helped to improve child health in these settings. Publications from three electronic databases (Web of Science, PubMed, Embase) up to 03/02/2022 were screened, with 14 papers meeting the inclusion criteria (rural setting in low/lower-middle income countries, presence of a community-facility linkage component, outcomes of interest related to under-five children's health, peer-reviewed articles containing original data written in English). We used Rosato's integrated conceptual framework for community participation to assess the transformative and community empowering capacities of the interventions, and realist principles to synthesize the outcomes. The results of this analysis highlight which conditions can lead to success of this type of intervention: active inclusion of hard-to-reach groups, involvement of community members in implementation's decisions, activities tailored to the actual needs of interventions' contexts, and usage of mixed methods for a comprehensive evaluation. These lessons informed the design of a community-facility linkage intervention and offer a framework to inform the development of monitor and evaluation plans for future implementations.

A Clinical Guide to Support the Implementation of Addiction Consult Services and the Value of Teaching and Technical Assistance

ABSTRACT

People with substance use disorders (SUDs) are increasingly admitted to general hospitals; however, many hospital systems lack both formal structures and skilled staff to provide high-quality care for inpatients with SUDs. Inpatient addiction consult services (ACSs), which are increasingly being implemented around the country, are an evidence-based strategy to add focused care for people with SUDs into the general medical setting. In 2018, New York City Health + Hospitals (H + H) launched an ACS program called Consult for Addiction Care and Treatment in Hospitals in six hospitals, supported by a team of addiction consult experts to deliver teaching and technical assistance (TTA) for the Consult for Addiction Care and Treatment in Hospitals ACSs. This commentary describes the TTA, which included site visits, introductory educational lectures, case conferences, ad hoc support, implementation assistance, and the creation of an addiction care guide. Similar TTA services could be used in the future when hospitals or systems want to launch novel clinical programs.

Strategies to improve delivery of equitable and evidence-informed care for pregnant and birthing people with a substance use disorder in acute care settings: A scoping review protocol

This protocol outlines a proposed scoping review to characterize evidence on implementation and quality improvement (QI) strategies that aim to improve equitable, evidence-informed care delivery for pregnant and birthing people with substance use disorder (SUD) in acute care. Untreated SUD during pregnancy is associated with an increased risk of overdose and severe maternal morbidity. Acute care settings are one important place to deliver equitable, evidence-informed clinical care. While clinical practice guidelines for substance use treatment and care of pregnant and birthing people with SUD exist, there are gaps in implementation. Our population of interest is pregnant and birthing people with SUD in an acute care setting. We will include US-based studies that describe or evaluate implementation or QI strategies, including experimental, observational, and descriptive studies published from 2016 to 2023. The proposed scoping review will be conducted in accordance with JBI methodology for scoping reviews and registered at OSF (registration number: BC4VZ). We will search MEDLINE (PubMed), CINAHL Complete (EBSCO), Scopus (Elsevier), and APA PsychInfo (Ovid) for published studies. Conference proceedings and Perinatal Quality Collaborative websites will be searched for grey literature. Two reviewers will independently screen then extract studies that meet inclusion criteria using a data extraction tool. The completion of this scoping review will help illuminate strengths and gaps in research and practice that aim to inform substance use treatment and care in acute care settings for pregnant and birthing people with SUD.

Integrating substance use peer support and screening brief intervention and referral to treatment services in the emergency department: a descriptive study of the ED leads program

BACKGROUND

The ED Leads program was introduced to 11 emergency departments (EDs) within New York City public hospitals from 2018 to 2019 to address a need for addiction support services in the ED. The purpose of this study is to (i) describe the ED Leads blended licensed-clinician and peer counselor team model in the ED at three hospitals, (ii) provide a descriptive analysis of patient engagement and referrals to substance use disorder (SUD) care post-intervention, and (iii) highlight potential barriers and facilitators to implementing the model.

METHODS

The program intended to combine Screening Brief Intervention and Referral to Treatment and peer support services. The authors analyzed electronic medical records data for patients encountered by ED Leads in the first 120 days of program launch. Data included the outcome of an encounter when a patient was engaged with one or both staff types, and 7-day attendance at an SUD treatment appointment when a patient accepted a referral within the 11-hospital system.

RESULTS

There were 1785 patients approached by ED Leads staff during the study period. Engagement differed by staff type and patient demographics, and encounter outcomes varied significantly by hospital. Eighty-four percent (N = 1503) of patients who were approached engaged with at least one staff type, and 6% (N = 86) engaged with both. Patients were predominantly male (N = 1438, 81%) with an average age of 45 (SD = 13), and enrolled in Medicaid (N = 1062, 59%). A majority (N = 801, 45%) had alcohol use disorder. Of the patients who accepted a referral within the system (N = 433), 63% received treatment services within 7 days of the ED Leads encounter, a majority at detoxification treatment (N = 252, 58%).

CONCLUSIONS

This study describes the potential value and challenges of implementing a blended peer counselor and licensed clinician model in the ED to provide SUD services. While teams provided a high volume of referrals and the analysis of post-intervention treatment follow up is promising, the blended team model was not fully realized, making it difficult to assess the benefits of this combined service. Further research might examine patient outcomes among ED patients who are offered services by both a peer counselor and licensed clinician.

Telephonic Outreach to Engage Patients with Substance Use Disorder Post-Hospitalization During the COVID-19 Pandemic

During the initial COVID-19 surge, one public hospital in NYC updated their post-discharge outreach approach for patients with substance use disorder, as part of the CATCH (Consult for Addiction Treatment and Care in Hospitals) program. Beginning April 1, 2020, three peers and two addiction counselors attempted telephonic outreach to patients who received a CATCH consultation during hospitalization from program launch (October 7, 2019) through March 31, 2020 (n = 329). Outreach calls could include counseling, in-depth peer support, and referrals to substance use services (SUS)-a significant expansion of the services offered via outreach pre-pandemic. CATCH staff successfully reached 29.5% of patients and provided 77.6% of them with supportive counseling and referrals. Thirty percent of unsuccessful calls were due to inactive numbers, and only 8% of patients without housing were reached. Telephonic outreach established a low-barrier connection between patients and SUS that may be valuable during any period, including non-COVID times. Future interventions that address social determinants such as housing and cell phone access concomitantly with substance use should be considered by addiction consultation services to potentially reduce acute care utilization and improve health outcomes.

Concussion injury management, perception, and knowledge in amateur field hockey

Background

Field hockey has a high risk for sports-related concussion (SRC) injuries due to the speed and intensity of the game, current rules, field surfaces and equipment composition. Head injuries are the second most common reported injury and up to 75% of SRCs go unreported or undetected. This increases the subsequent injury risk, long-term health consequences and prolonged injury recovery.

Objectives

This study aimed to examine the prevalence of SRC in hockey players within the Southern Gauteng Hockey Association (SGHA) premier league. Concussion knowledge and attitudes of hockey players, coaches, umpires, and officials were also investigated.

Methods

A partially mixed sequential dominant status design (QUANT-qual) was used, divided into two phases. In Phase One hockey players, coaches, umpires, and technical officials (n=119) completed a modified RoCKAS-ST questionnaire. In Phase Two, a focus group discussion with umpires (n=3) and interviews with coaches (n=3) were conducted.

Results

Injuries to the shoulder, neck, head, and face were reported from stick use (n=98); ball use (n=102) and collisions (n=187). Only 19% of hockey players were diagnosed with SRC, indicating that many of these injuries were undetected or not reported. Responses from the focus group discussion and interviews indicated that coaches, umpires, and officials felt they had insufficient knowledge of SRC.

Conclusion

The recognition and management of on-field injuries require improvement to enhance the injury detection system.

Pandemic telehealth flexibilities for buprenorphine treatment: a synthesis of evidence and policy implications for expanding opioid use disorder care in the United States

Buprenorphine is a highly effective treatment for opioid use disorder (OUD) and a critical tool for addressing the worsening US overdose crisis. However, multiple barriers to treatment-including stringent federal regulations-have historically made this medication hard to reach for many who need it. In 2020, under the COVID-19 public health emergency, federal regulators substantially changed access to buprenorphine by allowing prescribers to initiate patients on buprenorphine via telehealth without first evaluating them in person. As the public health emergency has been set to expire in May of 2023, Congress and federal agencies can leverage extensive evidence from studies conducted during the wake of the pandemic to make evidence-based decisions on the regulation of buprenorphine going forward. To aid policy makers, this narrative review synthesizes and interprets peer-reviewed research on the effect of buprenorphine flexibilities on the uptake and implementation of telehealth, and its impact on OUD patient and prescriber experiences, access to treatment, and health outcomes. Overall, our review finds that many prescribers and patients took advantage of telehealth, including the audio-only option, with a wide range of benefits and few downsides. As a result, federal regulators-including agencies and Congress-should continue nonrestricted use of telehealth for buprenorphine initiation.

Pathways to racial disparities in the effects of Good Samaritan Laws: A mixed methods pilot study

BACKGROUND

Drug overdose deaths continue to rise, and considerable racial inequities have emerged. Overdose Good Samaritan laws (GSLs) are intended to encourage overdose witnesses to seek emergency assistance. However, evidence of their effectiveness is mixed, and little is known regarding racial disparities in their implementation. This study examined GSL impact by assessing racial differences in awareness of and trust in New York state's GSL.

METHODS

Using a sequential mixed methods design, Black and white participants were recruited from an existing longitudinal cohort study of people who use illicit opioids in New York City to participate in a quantitative survey and qualitative interviews. Racially stratified survey responses were analyzed using chi-squared tests, Fisher exact tests, or t-tests. Qualitative interviews were analyzed using a hybrid inductive-deductive approach.

RESULTS

Participants (n=128) were 56% male and predominantly aged 50 years or older. Most met criteria for severe opioid use disorder (81%). Fifty-seven percent reported that the New York GSL makes them more likely to call 911 even though 42% reported not trusting law enforcement to abide by the GSL; neither differed by race. Black people were less likely to have heard of the GSL (36.1% vs 60%) and were less likely to have accurate information regarding its protections (40.4% vs 49.6%).

CONCLUSIONS

Though GSLs may reduce negative impacts of the criminalization of people who use drugs, their implementation may exacerbate existing racial disparities. Resources should be directed towards harm reduction strategies that do not rely on trust in law enforcement.

FEEDING PRACTICES AND NUTRITIONAL STATUS OF UNDER-FIVE CHILDREN IN A PERI-URBAN SETTING IN IBADAN, SOUTHWEST NIGERIA: A COMPARATIVE CROSS-SECTIONAL STUDY

Background

Existing literature suggests inequalities in nutritional and feeding practices for children in rural communities compared to their urban counterparts. However, with increasing urbanization and changing social norms, re-assessment of rural-urban differences in feeding practices for under-five children is essential. This study therefore aimed to assess the feeding practices and nutritional status of children in a peri-urban setting in Ibadan.

Methods

We conducted a community-based cross-sectional comparative study in peri-urban LGA (Lagelu) in Ibadan. Participants were 617 caregivers of underfive children identified, from wards typical of rural and urban settings, through a multistage sampling technique. Caregivers' sociodemographic details, 24-hour dietary recall of the child's feeding, and anthropometric measurements were obtained.

Results

Nearly half of the children were 2 years or older (rural: n=142, 47.2%; urban: n=147, 46.2%). There was significant difference between settings in terms of maternal age and education, father's education, caregiver's occupation and socioeconomic status. In total, 611 children (99.0%) were breastfed. Of those breastfed, 45% and 39% in rural and urban settings respectively were initiated within an hour of delivery. Children in rural setting had longer duration of breast feeding. However, they are less likely to be exclusively breast fed for 6 - months compared with children whose caregivers are urban dwellers. Dietary diversity was similar in both settings but higher among males. (20.3% male, 11.7% female in rural; 17.3% male and 15.5% female in urban). Overall, 108 (22.3%), 107 (21.9%), 152 (30.6%) and 34 (7.0%) of children aged 6-59 months were cachetic, underweight, stunted, and overweight respectively but commoner among children in rural settings.

Conclusion

Feeding and nutrition programmes need to apply a gender lens if sustained behavioural interventions on child nutrition are to reach equitable outcomes.

Pandemic telehealth flexibilities for buprenorphine treatment: A synthesis of evidence and policy implications for expanding opioid use disorder care in the U.S

Persistent Criminalization and Structural Racism in US Drug Policy: The Case of Overdose Good Samaritan Laws

The US overdose crisis continues to worsen and is disproportionately harming Black and Hispanic/Latino people. Although the "War on Drugs" continues to shape drug policy-at the disproportionate expense of Black and Hispanic/Latino people-states have taken some steps to reduce War on Drugs-related harms and adopt a public health-centered approach. However, the rhetoric regarding these changes has, in many cases, outstripped reality. Using overdose Good Samaritan Laws (GSLs) as a case study, we argue that public health-oriented policy changes made in some states are undercut by the broader enduring environment of a structurally racist drug criminalization agenda that continues to permeate and constrict most attempts at change. Drawing from our collective experiences in public health research and practice, we describe 3 key barriers to GSL effectiveness: the narrow parameters within which they apply, the fact that they are subject to police discretion, and the passage of competing laws that further criminalize people who use illicit drugs. All reveal a persisting climate of drug criminalization that may reduce policy effectiveness and explain why current reforms may be destined for failure and further disadvantage Black and Hispanic/Latino people who use drugs.

Cytomegalovirus infection is a risk factor for venous thromboembolism in ANCA-associated vasculitis

BACKGROUND

Venous thromboembolism (VTE) is a common complication in patients with anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV) and confers significant morbidity and mortality. Both acute and past cytomegalovirus (CMV) infection have been identified as risk factors for VTE in immunocompetent and immunosuppressed individuals. Here, we examine whether past exposure to CMV is a risk factor for VTE amongst patients with AAV.

METHODS

We retrospectively analysed outcomes of patients with a new diagnosis of AAV from a UK cohort. All confirmed cases of VTE where CMV IgG serology was available were recorded. Retrospective collection of the same data for patients at a North American centre was used as a validation cohort.

RESULTS

VTE was common with 12% of patients from the study cohort (total 259 patients) developing an event during the median follow-up period of 8.5 years of which 60% occurred within the first 12 months following diagnosis. Sixteen percent of CMV seropositive patients developed a VTE compared with 5% of patients who were seronegative (p = 0.007) and CMV seropositivity remained an independent predictor of VTE in multivariable analysis (HR 2.96 [1.094-8.011] p = 0.033). CMV seropositivity at diagnosis was confirmed as a significant risk factor for VTE in the American validation cohort (p = 0.032).

CONCLUSIONS

VTE is common in patients with AAV, especially within the first year of diagnosis. Past infection with CMV is an independent risk factor associated with VTE in AAV.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study

BACKGROUND

No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge.

METHODS

The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing.

FINDINGS

2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters.

INTERPRETATION

The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

816 COORDINATE MY CARE: INCREASING STAFF ACCESS AND NUMBER OF PATIENT RECORDS CREATED IN A BUSY ACUTE HOSPITAL - A QI PROJECT

Introduction

The Royal College of Physicians have emphasised the need to provide good end of life care for patients in the acute care setting, with the publication of the Acute Care Resource (1) in February 2021. This follows on from their key recommendations in 2018, which proposed that ‘all healthcare professionals reviewing patients with chronic conditions,…more than one serious medical problem, or terminal illness, should initiate shared decision making including advance care planning in line with patient preferences’ (2). Coordinate My Care (CMC) is an electronic urgent care plan accessible to all relevant health and social care professionals caring for patients residing in London Boroughs, enabling communication of wishes and preferences, including those of resuscitation status and advance care plans.

Method

Multiple PDSA Cycles, including requesting logins for CMC for emergency medicine, acute and general medical senior and junior doctors, and hosting CMC training sessions. Teaching sessions given to the above cohorts with regard to advance care planning and the use of CMC. Creation of live link to CMC via Trust’s electronic patient record.

Results

An increase in average monthly CMC record views from 45 to 108 by clinicians at North Middlesex Hospital. An increase from an average of 18 CMC records created per month, compared to 27 records created per month after the QI project, with an estimated additional cost saving of almost £19,000 per month (3).

Conclusion

Successful QI project, with demonstrated increase in staff access to CMC and number of patient CMC records created in a busy acute hospital. Ongoing success will be reflected in sustainability of the current numbers of acute hospital staff accessing CMC and creation of records.

Increased Attendance During Rapid Implementation of Telehealth for Substance Use Disorders During COVID-19 at the Largest Public Hospital System in the United States

OBJECTIVE

The objective of this study is to examine differences between; telehealth and in-person visits during COVID-19 and in a pre-COVID-19 reference period; COVID-19 televisit completion for patients with varying engagement in treatment during the reference period.

METHODS

Electronic medical record data were collected and analyzed with chi-squared or t-tests to compare patient demographics. Generalized estimating equations for estimating the odds of outcomes were used, controlling for demographics.

RESULTS

Patients were 3.34 and 1.74 times more likely to complete a telehealth visit (n = 11,839) compared with an in-person visit during (n = 7,917) and prior (n = 15,497) to COVID-19. For patients on buprenorphine, patients with no prior in-person visits during the pre-televisit period were 2.26 more likely to complete televisits compared with patients with two or more prior in-person visits. For all patients, those with two or more prior in-person visits in the reference period were 1.27 times more likely to complete a televisit compared with a patient with no in-person visits during the pre-televisit period. There was no significant difference when comparing with patients who had only one prior in-person visit to those patients with no prior visits.

CONCLUSIONS

In this study, outpatient substance use disorder (SUD) telehealth appointments were associated with higher odds of visit completion compared with in-person visits during and prior to COVID-19. Patients receiving buprenorphine, without prior in person visits, were more likely to attend if they did not have in-person visits prior to COVID-19. Regulators should consider permanently adopting telehealth flexibilities for SUD treatment once the federal emergency status has ended.

Mutant clones in normal epithelium outcompete and eliminate emerging tumours

Human epithelial tissues accumulate cancer-driver mutations with age1-9, yet tumour formation remains rare. The positive selection of these mutations suggests that they alter the behaviour and fitness of proliferating cells10-12. Thus, normal adult tissues become a patchwork of mutant clones competing for space and survival, with the fittest clones expanding by eliminating their less competitive neighbours11-14. However, little is known about how such dynamic competition in normal epithelia influences early tumorigenesis. Here we show that the majority of newly formed oesophageal tumours are eliminated through competition with mutant clones in the adjacent normal epithelium. We followed the fate of nascent, microscopic, pre-malignant tumours in a mouse model of oesophageal carcinogenesis and found that most were rapidly lost with no indication of tumour cell death, decreased proliferation or an anti-tumour immune response. However, deep sequencing of ten-day-old and one-year-old tumours showed evidence of selection on the surviving neoplasms. Induction of highly competitive clones in transgenic mice increased early tumour removal, whereas pharmacological inhibition of clonal competition reduced tumour loss. These results support a model in which survival of early neoplasms depends on their competitive fitness relative to that of mutant clones in the surrounding normal tissue. Mutant clones in normal epithelium have an unexpected anti-tumorigenic role in purging early tumours through cell competition, thereby preserving tissue integrity.

"When It's a Girl, They Have a Chance to Have Sex With Them. When It's a Boy…They Have Been Known to Rape Them": Perceptions of United Nations Peacekeeper-Perpetrated Sexual Exploitation and Abuse Against Women/Girls Versus Men/Boys in Haiti

Peacekeeping missions have been marred by reports of sexual exploitation and abuse (SEA) against local community members. However, there is limited research on how SEA against women/girls versus men/boys is perceived in peacekeeping host societies. In 2017 we collected micro-narratives in Haiti and then conducted a thematic analysis to understand how peacekeeper-perpetrated SEA was perceived by local community members comparing SEA against women/girls versus SEA against men/boys. Both male and female participants used language which suggested the normalization, in Haitian society, of both transactional sex with and rape of women/girls by UN personnel. In contrast, peacekeeper-perpetrated SEA against men/boys was viewed as unacceptable and was associated with homosexuality and related stigmatization. Overall, our results suggest that in Haiti, inequitable gender norms, the commodification of female sexuality, and homophobia result in SEA against males being recognized as a wrong that elicits outrage, while SEA against women/girls has been normalized. It is important to address the normalization of SEA against women/girls to prevent future violence and to recognize that SEA is also perpetrated against men/boys. Survivor-centered programs, sensitive to the needs of both male and female survivors, are required.

Towards transforming community eye care: an observational study and time-series analysis of optometrists' prescribing for eye disorders

OBJECTIVES

This study aimed to provide evidence on the therapeutic prescribing activity by community optometrists in Scotland and to determine its impact on workload in general practice and ophthalmology clinics.

STUDY DESIGN

Scottish administrative healthcare data for a 53-month period (November 2013-April 2018) were used to analyse non-medical prescribing practice by optometrists.

METHODS

Using interrupted time-series regression (Autoregressive Integrated Moving Average), we assessed the impact of optometrist prescribing on ophthalmology outpatient attendances and general practice prescribing for eye disorders.

RESULTS

A total of 54,246 items were prescribed by 205 optometrists over the study period. Since the commencement of data recording, optometrist prescribing activity increased steadily from a baseline of zero to 1.2% of all ophthalmic items prescribed. Neither the monthly number of items prescribed nor the size of optometric workforce were associated with a reduction in ophthalmology outpatient appointments over time.

CONCLUSIONS

Optometrists increasingly contribute to community ophthalmic prescribing in Scotland, releasing capacity and lessening general practice, but not secondary care workload. There appears to be an underutilisation of optometrists related to the management of dry eye, which represents an opportunity to release further capacity.

Rapid Telepsychiatry Implementation During COVID-19: Increased Attendance at the Largest Health System in the United States

OBJECTIVE

This study aimed to examine differences in completion rates between telepsychiatry and in-person visits during the COVID-19 pandemic and a prior reference period.

METHODS

The authors used electronic medical record data along with chi-squared or t tests to compare patients' demographic characteristics. Generalized estimating equations for estimating the odds of primary and secondary outcomes were used, controlling for demographic characteristics.

RESULTS

During COVID-19, the odds of completing a telepsychiatry visit (N=26,715) were 6.68 times the odds of completing an in-person visit (N=11,094). The odds of completing a telepsychiatry visit during COVID-19 were 3.00 times the odds of completing an in-person visit during the pre-COVID-19 reference period (N=40,318).

CONCLUSIONS

In this cross-sectional study, outpatient adult mental health clinic telepsychiatry appointments, largely by telephone, were strongly associated with a higher rate of visit completion compared with in-person visits during and prior to the COVID-19 pandemic. Regulators should consider permanently enabling reimbursement for telephone-only telepsychiatry visits.

AAPS Perspective on the EURL Recommendation on the use of Non-Animal-Derived Antibodies

In May 2020, the EU Reference Laboratory for alternatives to animal testing (EURL ECVAM) published a recommendation report entitled "Recommendation on nonanimal-derived antibodies". In this report, the EURL ECVAM specifically states: "Therefore, taking into consideration the ESAC Opinion on the scientific validity of replacements for animal-derived antibodies, EURL ECVAM recommends that animals should no longer be used for the development and production of antibodies for research, regulatory, diagnostic and therapeutic applications. The provisions of Directive 2010/63/EU should be respected, and EU countries should no longer authorise the development and production of antibodies through animal immunisation, where robust, legitimate scientific justification is lacking." (1). Here, we are providing the American Association of Pharmaceutical Scientists (AAPS) opinion on the EURL ECVAM recommendation report. In brief, there has been a clear and strong progress in reduction of animal use in the drug discovery and development process, including significant reduction of animal use in production of antibody reagents. Yet, it is proposed that more data need to be generated, shared and discussed within the scientific community before a decision to implement the change to non-animal derived antibodies is made.

'Physio's not going to repair a torn tendon': patient decision-making related to surgery for rotator cuff related shoulder pain

BACKGROUND

Rotator cuff related shoulder pain (RCRSP) is a common and disabling shoulder condition and surgical management is becoming more common. The rates and costs of surgical interventions have been on the rise. Understanding decision-making related to surgery and providing adequate information to people with RCRSP may improve patient-centred care and potentially reduce rates of surgery.

OBJECTIVES

To explore the decision-making processors of people who have undertaken surgery for RCRSP.

DESIGN

An in-depth thematic analysis.

METHOD

Interviews were conducted with patients from Melbourne who had had surgical management for RCRSP. Data were analysed using an inductive thematic approach.

RESULTS

Fifteen participants were recruited. Six key themes emerged: (1) Needing to get it done: "It was necessary to remedy the dire situation"; (2) Non-surgical treatment experience:" I knew that I'd done all I could"; (3) Mechanical problem:" Physio's not going to repair a torn tendon"; (4) Trust in medical professionals "If they told me that I needed to swallow a thousand spiders, I would have done it."; (5) Varied information sources "Dr Google played a big part in it"; (6) Organisational barriers "It was absolutely useless, my insurance."

CONCLUSION

Surgery appears to be commonly precipitated by unremitted severe symptoms and failed non-surgical treatment. While there was strong trust in highly trained surgeons, decision to undergo surgery also drew on questionable pathoanatomical beliefs and instances of inadequate patient information about treatment choices and risks that may be addressed by adopting a more patient-centred care approach.IMPLICATIONS FOR REHABILITATIONUnderstanding decision-making related to surgery and providing adequate information to people with rotator cuff related shoulder pain may improve patient-centred care.Surgery appears to be commonly precipitated by unremitted severe symptoms and failed non-surgical treatment.Decision to undergo surgery sometimes drew on questionable pathoanatomical beliefs.There was strong trust in highly trained surgeons but there were instances of inadequate patient information about treatment choices and risks.

Improving patient flow in acute psychiatric wards: enhanced bed management and trusted assessment

AIMS AND METHOD

In three localities in a mental health trust in England, an enhanced bed management team was established to improve patient flow and reduce out-of-area placements. Trusted assessments were provided to support risk management and conflict resolution. Two measures of flow were compared before and after the team was established.

RESULTS

The trusted assessment recommendation was for discharge in 70% of cases. The number of out-of-area placements was significantly reduced (P < 0.05), saving £616 876 over a 12-month period. Patient flow was significantly improved in one of the three localities as measured by patients/bed/6-month period (P < 0.05). In one of the other localities increased use of trusted assessment input and reduced numbers of patients being transferred in are recommended to improve flow.

CLINICAL IMPLICATIONS

Mental health trusts should consider the establishment of an enhanced bed management team, including trusted assessment, as a safe and cost-effective approach to improving patient flow and reducing the need for out-of-area placement.

Optimising the management of concurrent symphyseal/parasymphyseal and bilateral extracapsular condylar fractures using three-dimensional printing

PURPOSE

Three-dimensional (3D) printing plays an important role in the diagnosis and treatment planning of many elective procedures in oral and maxillofacial surgery (OMFS). 3D printers and the associated print materials are now within the price range of most maxillofacial units, requiring less work to be sent out to commercial printers. Whilst their use in the planning of elective procedures is commonplace, acute trauma is an area where 3D printing remains underutilised. The successful management of complex fracture patterns such as concomitant symphyseal/parasymphyseal and bilateral condylar fractures often warrants this approach.

METHODS

Freeware digital processing and manipulation software packages were used to view and segment structures from computed tomography (CT) data. Thereafter, fractures were digitally reduced. 3D printed models were produced from the digitally reduced models, allowing preoperative custom adaptation of osteosynthesis plates, facilitating accurate fracture fixation intraoperatively.

RESULTS

For less than one hundred pounds sterling (STG), a 3D printer (with print material) capable of producing a model of sufficient quality can be purchased. The use of freeware digital processing software allows digital manipulation of CT data. Production of 3D models and plate adaptation can be carried out within hours after CT examination.

CONCLUSIONS

The construction of digitally reduced 3D models and custom adapted plates enables the surgeon to achieve accurate fixation of complex fracture patterns in theatre which is clearly of benefit to patients. The potential for reduced theatre time also renders this approach more desirable, making this a worthwhile investment despite the additional non-clinical time associated with training and initial expenditure.

Understanding the relationship between pet owners and their companion animals as a key context for antimicrobial resistance-related behaviours: an interpretative phenomenological analysis

Objectives: Drivers of antimicrobial resistance (AMR) are diffuse and complex including a range of interspecies behaviours between pet owners and their animals. We employed interpretative phenomenological analysis (IPA) to explore the relationship between pet owners and their companion animals in relation to AMR. Design: Cross sectional, qualitative study. Methods: Semi-structured interviews were conducted with twenty-three British pet owners, transcribed verbatim and subjected to Interpretative Phenomenological Analysis (IPA). Results: Three, inter-related Superordinate themes are presented 1) 'They're my fur babies': unconditional love and anthropomorphism; 2) 'They share everything with you': affection and transmission behaviours; and 3) 'We would err on the side of caution': decision making and antibiotic use'. Conclusions: Affectionate behaviours between companion animals and their owners pose a risk for AMR transmission but they are so deeply treasured that they are unlikely to be amenable to change. In contrast, the promotion of appropriate antibiotic stewardship for pet owners and vets may offer a viable pathway for intervention development, benefitting from synergies with other interventions that target prescribers.

Identical and Nonidentical Twins: Risk and Factors Involved in Development of Islet Autoimmunity and Type 1 Diabetes

OBJECTIVE

There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings.

RESEARCH DESIGN AND METHODS

Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years.

RESULTS

At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects.

CONCLUSIONS

Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Routine splenic flexure mobilization may increase compliance with pathological quality metrics in patients undergoing low anterior resection

AIM

Mandatory splenic flexure mobilization (SFM) has been debated for rectal cancers. Proponents argue that additional mobilization facilitates a tension-free anastomosis; however, this must be weighed against heightened morbidity. Little is known about the impact of specific techniques on pathology quality metrics. We aim to determine the impact of SFM on pathology quality metrics for patients undergoing rectal resections for colorectal adenocarcinoma.

METHOD

Patients were selected by querying the University of Kansas electronic medical records and the American College of Surgeons National Surgical Quality Improvement Program database based on Current Procedural Terminology codes. Patients were categorized as SFM or non-SFM. Primary outcomes were node yield less than 12 and margin length.

RESULTS

There were 146 patients who met the inclusion criteria for chart review and 7369 included from the national database. Splenic flexure mobilization was associated with wider margins (3.52 vs 2.51 cm in low anterior resection, P < 0.01) and a decreased rate of inadequate nodal staging in patients undergoing low anterior resection (3.7% vs 19.3% P < 0.01).

CONCLUSIONS

SFM may affect surgical quality metrics in patients undergoing resection for distal colon and rectal adenocarcinoma. Further study is warranted to determine whether these differences in quality and pathology translate into differences in oncological outcomes.

Seroepidemiological Studies of Arboviruses in Africa

The literature on sero-epidemiological studies of flaviviral infections in the African continent is quite scarce. Much of the viral epidemiology studies have been focussing on diseases such as HIV/AIDS because of their sheer magnitude and impact on the lives of people in the various affected countries. Increasingly disease outbreaks caused by arboviruses such as the recent cases of chikungunya virus, dengue virus and yellow fever virus have prompted renewed interest in studying these viruses. International agencies from the US, several EU nations and China are starting to build collaborations to build capacity in many African countries together with established institutions to conduct these studies. The Tofo Advanced Study Week (TASW) was established to bring the best scientists from the world to the tiny seaside town of Praia do Tofo to rub shoulders with African virologists and discuss cutting-edge science and listen to the work of researchers in the field. In 2015 the 1st TASW focussed on Ebola virus. The collections of abstracts from participants at the 2nd TASW which focused on Dengue and Zika virus as well as presentations on other arboviruses are collated in this chapter.

Exploring the behavioural drivers of veterinary surgeon antibiotic prescribing: a qualitative study of companion animal veterinary surgeons in the UK

Background

Multi-drug resistant bacteria are an increasing concern in both human and veterinary medicine. Inappropriate prescribing and use of antibiotics within veterinary medicine may be a contributory factor to antimicrobial resistance (AMR). The ‘One Health’ Initiative aims to work across species and environments to reduce AMR, however; little is currently known about the factors which influence antibiotic prescribing among veterinary surgeons in companion animal practice.

This paper reports on qualitative data analysis of interviews with veterinary surgeons whose practice partially or wholly focuses on companion animals (N = 16). The objective of the research was to explore the drivers of companion animal veterinary surgeons’ antibiotic prescribing behaviours. The veterinary surgeons interviewed were all practising within the UK (England (n = 4), Scotland (n = 11), Northern Ireland (n = 1)). A behavioural thematic analysis of the data was undertaken, which identified barriers and facilitators to specific prescribing-related behaviours.

Results

Five components of prescribing behaviours were identified: 1) confirming clinical need for antibiotics; 2) responding to clients; 3) confirming diagnosis; 4) determining dose, duration and type of antibiotic; and 5) preventing infection around surgery (with attendant appropriate and inappropriate antibiotic prescribing behaviours). Barriers to appropriate prescribing identified include: business, diagnostic, fear, habitual practice and pharmaceutical factors. Facilitators include: AMR awareness, infection prevention, professional learning and regulation and government factors.

Conclusion

This paper uses a behavioural lens to examine drivers which are an influence on veterinary surgeons’ prescribing behaviours. The paper contributes new understandings about factors which influence antibiotic prescribing behaviours among companion animal veterinary surgeons. This analysis provides evidence to inform future interventions, which are focused on changing prescribing behaviours, in order to address the pressing public health concern of AMR.

A Type 1 Diabetes Genetic Risk Score Predicts Progression of Islet Autoimmunity and Development of Type 1 Diabetes in Individuals at Risk

OBJECTIVE

We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals.

RESEARCH DESIGN AND METHODS

We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables.

RESULTS

Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002).

CONCLUSIONS

The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Barriers and enablers to meticillin-resistant Staphylococcus aureus admission screening in hospitals: a mixed-methods study

BACKGROUND

To reduce the risk of transmission of meticillin-resistant Staphylococcus aureus (MRSA), international guidelines recommend admission screening to identify hospital patients at risk of colonization. However, routine monitoring indicates that optimum screening compliance levels are not always achieved. In order to enhance compliance, we must better understand those factors which influence staff screening behaviours.

AIM

To identify factors which influence staff compliance with hospital MRSA screening policies.

METHODS

A sequential two-stage mixed-methods design applied constructs from normalization process theory and the theoretical domains framework to guide data collection and analysis. Initial qualitative findings informed subsequent development of a national cross-sectional survey of nursing staff (N = 450). Multiple regression modelling identified which barriers and enablers best predict staff compliance.

FINDINGS

Three factors were significant in predicting optimum (>90%) compliance with MRSA screening: having MRSA screening routinized within the admission process; category of clinical area; feedback of MRSA screening compliance within the clinical area. Integration of data-sets indicated that organizational systems which 'make doing the right thing easy' influence compliance, as does local ward culture. Embedded values and beliefs regarding the relative (de)prioritization of MRSA screening are important.

CONCLUSION

To our knowledge, this is the first study to provide original evidence of barriers and enablers to MRSA screening, applying both sociological and psychological theory. As antimicrobial resistance is a global health concern, these findings have international relevance for screening programmes. Future policy recommendations or behaviour change interventions, based on the insights presented here, could have significant impact upon improving screening compliance.

Chemically linked metal-matrix nanocomposites of boron nitride nanosheets and silver as thermal interface materials

Herein, novel hybrid nanocomposite thermal interface materials (TIMs) relying on the chemical linkage of silver, boron nitride nanosheets (BNNSs), and organic ligands are reported. These TIMs were prepared using a co-electrodeposition/chemisorption approach where the electrolytic reduction of silver ions into silver nano-/micro-crystals was coupled with the conjugation of ligand-coated nanosheets onto silver crystals. Furthermore, the influence of the bond strength of silver/nanosheet links on the thermal, mechanical, and structural properties is investigated using a combination of techniques including laser flash analysis, phase-sensitive transient thermoreflectance, nanoindentation, and electron microscopy. The internal nanostructure was found to be strongly dependent on the linker chemistry. While the chemical grafting of 4-cyano-benzoyl chloride (CBC) and 2-mercapto-5-benzimidazole carboxylic acid (MBCA) on BNNSs led to the uniform distribution of functionalized-nanosheets in the silver crystal matrix, the physical binding of 4-bromo-benzoyl chloride linkers on nanosheets caused the aggregation and phase separation. The thermal conductivity was 236-258 W m^-1 K and 306-321 W m^-1 K for physically and chemically conjugated TIMs, respectively, while their hardness varied from 400-495 MPa and from 240 to 360 MPa, respectively. The corresponding ratio of thermal conductivity to hardness, which is a critical parameter controlling the performance of TIMs, was ultrahigh for the chemically conjugated TIMs: 1.3 × 10^-6 m² K^-1 s for MBCA-BNNS and 8.5 × 10^-7 m² K^-1 s for CBC-BNNS. We anticipate that these materials can satisfy some of the emerging thermal management needs arising from the improved performance and efficiency, miniaturization, and/or high throughput of electronic devices, energy storage devices, energy conversion systems, light-emitting diodes, and telecommunication components.

A British Ophthalmological Surveillance Unit Study on metastatic endogenous endophthalmitis

PurposeEndogenous endophthalmitis (EE) is a rare but serious ocular infection caused by the seeding of bacteria into the eye from a source elsewhere in the body. Studies suggest that EE accounts for 2 to 8% of all endophthalmitis.MethodsA prospective observational study was conducted using the British Ophthalmological Surveillance Unit reporting system. Questionnaires were sent to reporting Ophthalmologists in the UK to assess incidence, underlying aetiology, eye findings, management, and final outcomes in endogenous endophthalmitis over a 12-month period within the British Isles.ResultsSixty two cases reported with 48 initial questionnaires returned and 25 6-month follow-up questionnaires returned. The median age of patients affected was 57 years with youngest aged 2 years and oldest aged 85 years. Twenty three were male and 24 were female. The median visual acuity in the affected eye was 3 logMAR (range -0.1 to 5). Blood cultures were taken in 36 patients, 58% of which were positive. Vitreous biopsy was taken in 35 patients, 23% of which were culture positive. The visual function as assessed by visual acuity had significantly improved at 6 months with a median acuity of 0.18 logMAR (P=0.003).ConclusionsThe survey demonstrates the severe nature of endogenous endophthalmitis in patients with active infection or with risk factors for infection. Our study has demonstrated that at least half of the patients who were treated had significant vision improvement.
