Biomechanical parameters of the golf swing associated with lower back pain: A systematic review

Low back pain (LBP) is the most common injury in golfers of all abilities. The primary aim of this review was to improve understanding of human golf swing biomechanics associated with LBP. A systematic review using the PRISMA guidelines was performed. Nine studies satisfying inclusion criteria and dually reporting golf swing biomechanics and LBP were identified. Human golf swing biomechanics potentially associated with LBP include: reduced lumbar flexion velocity; reduced transition phase length; reduced lumbar torsional load; earlier onset of erector spinae contraction; increased lumbar lateral flexion velocity; reduced or greater erector spinae activity; and earlier onset of external oblique contraction. These potential associations were undermined by a very limited and conflicting quality of evidence, study designs which introduced a severe potential for bias and a lack of prospective study design. There is no conclusive evidence to support the commonly held belief that LBP is associated with "poor" golf swing technique. The potential associations identified should be further investigated by prospective studies of robust design, recruiting participants of both sexes and dexterities. Once firm associations have been identified, further research is required to establish how this knowledge can be best integrated into injury prevention and rehabilitation.

Childhood-Onset Lupus Nephritis in the Childhood Arthritis and Rheumatology Research Alliance Registry: Short-Term Kidney Status and Variation in Care

OBJECTIVE

The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis.

METHODS

We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded.

RESULTS

We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers.

CONCLUSION

In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

A systematic review and meta-analysis of global and social functioning among people at risk of bipolar disorder

BACKGROUND

Functional status could predict development of bipolar disorder (BD) or have clinical significance. The relationship between BD risk and functioning is poorly understood. We undertook a systematic review examining the global and social functioning of those at risk for BD.

METHODS

We examined observational studies comparing a risk sample with healthy controls or full-threshold BD participants, using measures of global or social functioning. Risk status included family history of BD, meeting risk criteria, or having prodromal symptomatology, or premorbid functioning of persons with BD. Medline, PsycINFO, and Embase were searched. The Newcastle-Ottawa Scale for Cross-Sectional Studies was used to assess quality. Meta-analyses were performed where possible.

RESULTS

7215 studies were screened and 40 studies were included (8474 participants). Risk samples had poorer functioning than controls, and superior functioning to participants with BD. Meta-analysis indicated poorer global functioning among persons with familial risk compared to healthy controls (mean global functional difference: 5.92; 95 % confidence interval: 7.90, 3.95; mean premorbid functioning difference: 2.31; 95 % confidence interval: 0.70, 3.92). Studies with higher proportions of female participants had slightly poorer global functioning. High heterogeneity was attributable functional measures and potentially functionally differential subgroups within the risk samples.

LIMITATIONS

Broader measures of functioning, such as neurocognition and behavioural measures, were excluded. Measures of global functioning are limited by conflating functioning and symptoms.

CONCLUSIONS

Functioning in the BD risk populations is intermediate to that of healthy controls and persons with BD, indicating their value in definitions of BD risk, in itself a likely heterogeneous state.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry

BACKGROUND

Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months.

METHODS

We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed.

RESULTS

We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05).

CONCLUSION

While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Healthcare use by children in North West London 2015-2019 by deprivation and integrated care access

Background

England has a health system offering universal coverage, but disparities in healthcare use are increasing. Between 2007-2017, children living in more deprived areas had higher rates of unplanned care (Emergency Department (ED) attendance and hospital admissions), whereas children from less deprived areas had higher rates of planned care (General Practitioner (GP) contact and outpatient appointments). More detailed research to find solutions for this divergent pattern is required.

Aim

To assess the rates of GP contact, outpatient appointments, hospital admissions and ED attendance in North West London, by Index of Multiple Deprivation (IMD) decile of home postcode and access to an integrated care service providing linked care between multiple child health professionals ‘Connecting Care for Children (CC4C)', for children aged 0-18 years between 2015-2019.

Methods

Retrospective analysis of a de-identified database of integrated care records for 495,357 children.

Results

Children from the most deprived decile had higher rates of emergency admissions (0.070 per child per year vs. overall mean 0.040), elective admissions (0.076 vs. 0.032), ED attendances (0.754 vs. 0.358) and outpatient appointments (1.702 vs. 0.756) between 01.01.2015- 31.12.2019. Children from the least deprived decile had the second highest rates of outpatient appointments (0.911 vs. 0.756) and GP contact (8.192 vs. 5.390) between 01.01.2015- 31.12.2019. Children with access to the CC4C service, despite being from more deprived backgrounds, had lower rates of emergency admissions (0.028 vs. 0.037) compared to patients with access to usual care. P values &lt;0.001 in all cases.

Conclusions

Greater deprivation was linked to higher rates of emergency admissions, but this was partially mitigated by access to more integrated healthcare models. Children from the least deprived decile continued to have disproportionately higher use of planned care.

Key messages

• Despite universal health coverage, children from more deprived areas continue to have disproportionately higher use of unplanned care.

• Further research is required to explore whether integrated care solutions can reduce the burden on unplanned health services and inequalities in access to care.

TRENDS IN HIV CARE OUTCOMES AMONG ADULTS AND ADOLESCENTS IN THE U.S. SOUTH, 2015-2019

PURPOSE

HIV disparities continue to persist in the southern United States and among some populations. Early HIV diagnosis, prompt linkage to care, and viral suppression among persons with HIV in the South, in particular the Deep South, are critical to reduce disparities and achieve national prevention goals.

METHODS

Estimated annual percent changes were calculated to assess trends during 2015-2019 in percentage distributions for stage of disease at the time of diagnosis, linkage to HIV medical care, and viral suppression.

RESULTS

Among 95,488 persons with HIV diagnosed in the South (Deep South: 81,848; Other South:13,640), the overall percentage that received a diagnosis classified as stage 0 increased 9.0%, stages 1-2 increased 1.8%, linkage to HIV care increased 2.9%, and viral suppression increased 5.9%. Changes in care outcomes among American Indian/Alaska Native persons and persons with infection attributed to injection drug use were minimal.

CONCLUSIONS

To reach the goals of Ending the HIV Epidemic (EHE) and other federal initiatives, efforts need to focus on prevention and care among persons residing in the South. Addressing factors such as stigma and discrimination and elimination of barriers to HIV testing, care, and treatment are needed to effectively address these disparities in HIV-related care outcomes.

MEdication Management in older people with Intellectual Disabilities (MEMID): a scoping review

Introduction

Globally, around 1 in 100 adults have intellectual disabilities (ID) (synonymous with learning disability in the UK) (1) yet their needs in terms of healthcare in general and medication management in particular, are under-researched. People with ID have more comorbidities compared with those without ID and around one third of older people (≥ 50 years) with ID (OPwID) have two or more chronic conditions, putting them at risk of polypharmacy (use of multiple medicines) (2).

Aim

To undertake a scoping review to gather evidence on the barriers and facilitators in the medication management of OPwID from a multi-stakeholder (patient, carer and healthcare professional) perspective.

Methods

Standard scoping review methods were used. Electronic databases (Medline, PsycINFO) were searched from 2011-2021 using a range of search terms. Studies were included if they involved: OPwID without dementia (all types); healthcare professionals or caregivers caring for individuals with ID; problems related to medication use. The review was restricted to studies in the English language.

The PRISMA-ScR checklist and reporting standards was used to conduct and report the review. Independent duplicate screening and data extraction was undertaken. The quality of studies was not formally assessed. A narrative synthesis was conducted to summarise the results and included barriers and facilitators associated with medicines management from patients’/carers’ and professionals’ perspectives.

Results

Eight studies were included, of which seven used qualitative methods. The majority of studies were undertaken in Europe ((the Netherlands (2), Norway (1), Belgium (1), UK (3)) and one was conducted in the US.

Patients/carers reported several barriers/facilitators:

The most cited barriers to medication management of OPwID from professionals’ perspective included: limited knowledge of, and training about, ID; nonadherence to guideline recommendation; and lack of coordination between different professionals in multidisciplinary teams.

Conclusion/Discussion

The review was restricted to two databases and the English language due to resource- and time-constraints. All the included studies were conducted in developed countries with different healthcare settings/practice. As such, the findings might not be generalisable to other less/under-developed countries or settings.

There is limited empirical evidence regarding the medication management of OPwID, in particular, facilitators to medicines management from professionals’ perspective. OPwID are a highly vulnerable population for whom medications have an important role in managing their multiple morbidities. This review highlights an evidence gap regarding the medication management of these individuals. The results will be used to inform the development of personalised intervention(s) to improve the safe and effective use of medication in this population.

A national initiative to promote public involvement in medicine safety in Scotland: the use of a population survey to identify candidate behaviours for intervention development

Introduction

Medicines are the most commonly used healthcare intervention (1). Every medicine has benefits and harms. One of the five objectives of the WHO Global Patient Safety campaign, Medication Without Harm, is to “empower patients, families and their carers to become actively involved and engaged in treatment or care decisions, ask questions, spot errors and effectively manage their medications” (2). Effective strategies are needed to promote greater public involvement in the safe and effective use of medicines.

Aim

The aim of this study was to explore the prevalence of public behaviour in terms of information-/advice-seeking about medicines in general, newly prescribed medicines, and pain management including their use of oral, over-the-counter (OTC) analgesics. The survey also included exploration of self-reported behaviour regarding their use of pharmacies and OTC analgesics.

Methods

A cross-sectional online survey of 1000 adults (aged &gt;16years) in Scotland was undertaken in collaboration with Ipsos MORI. The content was informed by a multi-stakeholder prioritisation event (held in November 2019) and supplemented with information from earlier studies, including national surveys using Citizen Panels. The following themes were included in the questionnaire:

The data were input online by respondents then cleaned and weighted by Ipsos Mori using random iterative method (RIM) weighting to the known offline population proportions for age, gender, region and working status. All data were analysed and presented using descriptive statistics.

Results

Most respondents (78%, n=777) had used a pharmacy in the previous 12 months to obtain a prescription medicine and slightly fewer (61%, n=610) to obtain an OTC medicine. Low levels of information- and advice-seeking were reported especially on receipt of new prescription medicines.

Few (5%) respondents ‘always’ discussed their new prescription medicine with pharmacy staff and 29% reported ‘never’ engaging in this behaviour. Older people (&gt; 35 years) were less likely to engage in this behaviour. Up to 65% of respondents reported ‘always’ engaging with specific aspects of the appropriate use of OTC analgesics e.g. appropriate dose.

Potentially unsafe behaviours were identified with medicine disposal. Nearly one third (29%) of respondents considered waste bin disposal to be of low or no harm, and 19% considered disposal of medicines via the toilet/sink to be of low/no harm.

Conclusion

Despite the extensive use of pharmacies, low levels of information-/advice-seeking were reported especially on receipt of new prescription medicines. Potentially unsafe behaviours were also identified with medicine use and disposal. The key determinants of these behaviours will be explored in more detail and theory-based interventions will be developed and tested to evaluate their effect.

Respondent opinion (positively or negatively) regarding their perceptions regarding community pharmacies and/or pharmacy personnel could have been influenced by the increased use and/or awareness of community pharmacy services due to the pandemic.

Social determinants of health influence disease activity and functional disability in Polyarticular Juvenile Idiopathic Arthritis

BACKGROUND

Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry.

METHODS

In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months.

RESULTS

One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability.

CONCLUSION

High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Communicating During an HIV Outbreak Among People Who Inject Drugs-West Virginia 2019

In 2019, the West Virginia Bureau for Public Health (WV BPH), Cabell-Huntington Health Department (CHHD), and CDC collaborated to respond to an HIV outbreak among people who inject drugs (PWID). CDC, WV BPH, and CHHD formed a cross-agency communications team to establish situational awareness, identify knowledge gaps, and establish key audiences for messages, including the general population, PWID, and clinical and social service providers. The team disseminated up-to-date information about the outbreak, and prioritized messages addressing stigma related to drug use, syringe services programs, and HIV. Messages were continually updated to address the evolving situation and to resonate with local values. Messages were disseminated via advertisements, local news media, and directly to PWID, people experiencing homelessness, and providers. The response supplemented CHHD's assets, including strong relationships and community knowledge, with staff capacity and expertise from state and federal agencies. This collaborative approach is a useful model to address communication needs.

In situ evaluation of contact stiffness in a slip interface with different roughness conditions using ultrasound reflectometry

Understanding the dynamic condition of the interface between a railway wheel and rail is important to reduce the risks and consider the effectiveness of countermeasures for tribological problems. Traditionally the difficulty in obtaining accurate non-destructive interfacial measurements has hindered systematic experimental investigations. Recently, an ultrasound reflectometry technique has been developed as a direct observation method of a rolling–sliding interface; however, the topography dependence under the high contact pressures in a wheel–rail contact has not been clarified. For this reason, a novel in situ measurement of the contact stiffness using ultrasound reflectometry was carried out for three different levels of roughness. A contact pressure equivalent to that in a wheel–rail interface was achieved by using a high-pressure torsion test approach. The dynamic change of contact stiffness with slip was measured using ultrasound and the influence of roughness was investigated. The measured changes were validated using a newly developed numerical simulation, and mechanisms to explain the observed behaviour were proposed in terms of fracture and plastic deformation of the asperity bonds. These findings could help in understanding the traction characteristics for different roughness conditions and also assist in understanding damage mechanisms better, such as wear and rolling contact fatigue.

Response to a Large HIV Outbreak, Cabell County, West Virginia, 2018-2019

INTRODUCTION

In January 2019, the West Virginia Bureau for Public Health detected increased HIV diagnoses among people who inject drugs in Cabell County. Responding to HIV clusters and outbreaks is 1 of the 4 pillars of the Ending the HIV Epidemic in the U.S. initiative and requires activities from the Diagnose, Treat, and Prevent pillars. This article describes the design and implementation of a comprehensive response, featuring interventions from all pillars.

METHODS

This study used West Virginia Bureau for Public Health data to identify HIV diagnoses during January 1, 2018-October 9, 2019 among (1) people who inject drugs linked to Cabell County, (2) their sex or injecting partners, or (3) others with an HIV sequence linked to Cabell County people who inject drugs. Surveillance data, including HIV-1 polymerase sequences, were analyzed to estimate the transmission rate and timing of infections using molecular clock phylogenetic analysis. Federal, state, and local partners designed and implemented a comprehensive response during January 2019-October 2019.

RESULTS

Of 82 people identified in the outbreak, most were male (60%), were White (91%), and reported unstable housing (80%). In a large molecular cluster containing 56 of 60 (93%) available sequences, 93% of inferred transmissions occurred after January 1, 2018. HIV testing, HIV pre-exposure prophylaxis, and syringe services were rapidly expanded, leading to improved linkage to HIV care and viral suppression.

CONCLUSIONS

Evidence of rapid transmission in this outbreak galvanized robust collaboration among federal, state, and local partners, leading to critical improvements in HIV prevention and care services. HIV outbreak response requires increased coordination and creativity to improve service delivery to people affected by rapid HIV transmission.

HIV Cluster and Outbreak Detection and Response: The Science and Experience

The Respond pillar of the Ending the HIV Epidemic in the U.S. initiative, which consists of activities also known as cluster and outbreak detection and response, offers a framework to guide tailored implementation of proven HIV prevention strategies where transmission is occurring most rapidly. Cluster and outbreak response involves understanding the networks in which rapid transmission is occurring; linking people in the network to essential services; and identifying and addressing gaps in programs and services such as testing, HIV and other medical care, pre-exposure prophylaxis, and syringe services programs. This article reviews the experience gained through 30 HIV cluster and outbreak responses in North America during 2000-2020 to describe approaches for implementing these core response strategies. Numerous jurisdictions that have implemented these response strategies have demonstrated success in improving outcomes related to HIV care and viral suppression, testing, use of prevention services, and reductions in transmission or new diagnoses. Efforts to address important gaps in service delivery revealed by cluster and outbreak detection and response can strengthen prevention efforts broadly through multidisciplinary, multisector collaboration. In this way, the Respond pillar embodies the collaborative, data-guided approach that is critical to the overall success of the Ending the HIV Epidemic in the U.S. initiative.

Improving provider, patient and health systems outcomes: a qualitative analysis of Project ECHO

Background

Project ECHO (Extension for Community Healthcare Outcomes) is an internationally recognised tele-mentoring intervention that has been implemented in over 40 countries. The model connects specialist healthcare providers (hubs) with providers in primary and community practice (spokes), often in rural and isolated areas.

Objectives

Project ECHO aims to improve healthcare provider's skills, confidence and knowledge, and to create a community of practitioners using the hub and spoke model. Analysing interview data from 27 Project ECHO network leads and participants in Northern Ireland, this study sought to assess the impact of Project ECHO on improving provider, patient and health system outcomes.

Results

Having access to a specialist, a space to share experiences, and being able to disseminate up-to-date best practice were all cited as improving provider knowledge. Providers described improved outcomes for patients such as receiving a new treatment or an efficient referral. Providers reported being more confident in managing patients and thus were less likely to refer unnecessarily, and links between providers at primary and secondary levels being improved. ECHO was deemed an acceptable methodology in terms of format and in improving access to education and training by removing geographic barriers and reducing time barriers.

Conclusions

This is one of the first studies to qualitatively analyse outcomes across a number of different ECHO networks, and involving both health and social care networks. The results indicate the benefit of ECHO in improving provider, patient and healthcare outcomes. This has implications for future resourcing decisions, particularly within the context of COVID-19 in which virtual and online training is necessitated by social distancing requirements. This study has implications for wider international contexts in which ECHO may be piloted to address similar challenges.

Key messages

Participants across our study described Project ECHO as having a positive impact on provider, patient and health systems outcomes.

Project ECHO was described as an acceptable approach to training and education that improved access through removing geographic barriers.

Case report: NTRK1-rearranged cervical sarcoma with fibrosarcoma like morphology presenting in a 13-year-old managed with a neo-adjuvant TRK-inhibitor and surgical excision

•

NTRK fusion-positive fibrosarcoma like tumour of the cervix in a paediatric patient.

•

Fertility sparing surgery achieved with the use of a neo-adjuvant TKi.

•

Identifying NTRK fusions may afford conservative treatment options in these tumours.

This case report reviews the case of a 13-year-old patient who presented with a 9 cm NTRK1-rearranged cervical sarcoma with fibrosarcoma like morphology. At presentation the lesion filled her vagina and pelvis and any attempt at surgical removal would have been morbid and led to loss of fertility. These neoplasms are extremely rare with 18 cases of the uterine cervix reported in the literature, none of which have occurred in a paediatric patient, and none of whom have received neo-adjuvant therapy prior to excision. Based upon evidence that has shown good tolerability and responses of paediatric NTRK fusion-positive solid tumours to TRK inhibitors, both in the neo-adjuvant and upfront setting, this patient was managed with neo-adjuvant entrectinib. Following a dramatic reduction in tumour size confirmed by imaging, she underwent conservative fertility sparing surgery with final histopathology showing no residual disease.

Risk factors for persistent abnormality on chest radiographs at 12-weeks post hospitalisation with PCR confirmed COVID-19

Background

The long-term consequences of COVID-19 remain unclear. There is concern a proportion of patients will progress to develop pulmonary fibrosis. We aimed to assess the temporal change in CXR infiltrates in a cohort of patients following hospitalisation for COVID-19.

Methods

We conducted a single-centre prospective cohort study of patients admitted to University Hospital Southampton with confirmed SARS-CoV2 infection between 20th March and 3rd June 2020. Patients were approached for standard-of-care follow-up 12-weeks after hospitalisation. Inpatient and follow-up CXRs were scored by the assessing clinician for extent of pulmonary infiltrates; 0–4 per lung (Nil = 0, < 25% = 1, 25–50% = 2, 51–75% = 3, > 75% = 4).

Results

101 patients with paired CXRs were included. Demographics: 53% male with a median (IQR) age 53.0 (45–63) years and length of stay 9 (5–17.5) days. The median CXR follow-up interval was 82 (77–86) days with median baseline and follow-up CXR scores of 4.0 (3–5) and 0.0 (0–1) respectively. 32% of patients had persistent CXR abnormality at 12-weeks. In multivariate analysis length of stay (LOS), smoking-status and obesity were identified as independent risk factors for persistent CXR abnormality. Serum LDH was significantly higher at baseline and at follow-up in patients with CXR abnormalities compared to those with resolution. A 5-point composite risk score (1-point each; LOS ≥ 15 days, Level 2/3 admission, LDH > 750 U/L, obesity and smoking-status) strongly predicted risk of persistent radiograph abnormality (0.81).

Conclusion

Persistent CXR abnormality 12-weeks post COVID-19 was common in this cohort. LOS, obesity, increased serum LDH, and smoking-status were risk factors for radiograph abnormality. These findings require further prospective validation.

Increasing Capacity to Detect Clusters of Rapid HIV Transmission in Varied Populations-United States

Molecular cluster detection analyzes HIV sequences to identify rapid HIV transmission and inform public health responses. We describe changes in the capability to detect molecular clusters and in geographic variation in transmission dynamics. We examined the reporting completeness of HIV-1 polymerase sequences in quarterly National HIV Surveillance System datasets from December 2015 to December 2019. Priority clusters were identified quarterly. To understand populations recently affected by rapid transmission, we described the transmission risk and race/ethnicity of people in clusters first detected in 2018–2019. During December 2015 to December 2019, national sequence completeness increased from 26% to 45%. Of the 1212 people in the 136 clusters first detected in 2018–2019, 69% were men who have sex with men (MSM) and 11% were people who inject drugs (PWID). State-by-state analysis showed substantial variation in transmission risk and racial/ethnic groups in clusters of rapid transmission. HIV sequence reporting has increased nationwide. Molecular cluster analysis identifies rapid transmission in varied populations and identifies emerging patterns of rapid transmission in specific population groups, such as PWID, who, in 2015–2016, comprised only 1% of people in such molecular clusters. These data can guide efforts to focus, tailor, and scale up prevention and care services for these populations.

A systematic review of pharmacist-led audit and feedback interventions to influence prescribing behaviour in general practice settings

Introduction

Audit and Feedback (A&F) involves measuring data about practice, comparing it with clinical guidelines, professional standards or peer performance, and then feeding back the data to individuals/groups of health professionals to encourage change in practice (if required). A 2012 Cochrane review (1) found A&F was effective in changing health professionals’ behaviour and suggested that the person who delivers the A&F intervention influences its effect. Increasingly, pharmacists work in general practice and often have responsibility for medication review and repeat prescriptions. The effectiveness of pharmacist-led A&F in influencing prescribing behaviour is uncertain.

Aim

This secondary analysis from an ongoing update of the original Cochrane review aims to identify and describe pharmacist-led A&F interventions and evaluate their impact on prescribing behaviour in general practice compared with no intervention.

Methods

This sub-review is registered with PROSPERO: CRD42020194355 and complies with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (2). For the updated Cochrane review, the Cochrane Effective Practice and Organization of Care Group searched MEDLINE (1946 to present), EMBASE, CINAHL and Cochrane Library (March 2019) to identify randomised trials featuring A&F interventions. For this sub-review, authors screened titles and abstracts (May 2020) to identify trials involving pharmacist-led A&F interventions in primary care, extracted data, and assessed risk of bias (RoB) in eligible studies. Review results are summarised descriptively. Heterogeneity will be assessed and a random-effects meta-analysis is planned. Publication bias for selected outcomes and the certainty of the body of evidence will be evaluated and presented. Sub-group analyses will be conducted.

Results

Titles and abstracts of 295 studies identified for inclusion in the Cochrane A&F review update were screened. Eleven studies (all cluster-randomised trials) conducted in 9 countries (Denmark, Italy, Netherlands, Norway, Republic of Ireland, UK, Australia, Malaysia, USA) were identified for inclusion (Figure 1). Six studies had low RoB, two had high risk due to dissimilarities between trial arms at baseline and/or insufficient detail about randomisation, and three studies had unclear RoB. Studies examined the effect of A&F on prescribing for specific conditions (e.g. hypertension), medications (e.g. antibiotics), populations (e.g. patients &gt;70), and prescribing errors (e.g. inappropriate dose). The pharmacist delivering A&F was a colleague of intervention participants in five studies. Pharmacists’ levels of skill and experience varied; seven studies reported details of pharmacist training undertaken for trial purposes. A&F interventions in nine studies demonstrated changes in prescribing, including reductions in errors or inappropriate prescribing according to the study aims and smaller increases in unwanted prescribing compared with the control group. Data analyses are ongoing (results will be available for the conference).

Conclusion

The preliminary results demonstrate the effectiveness of pharmacist-led A&F interventions in different countries and health systems with influencing prescribing practice to align more closely with guidance. Studies measured different prescribing behaviours; meta-analysis is unlikely to include all 11 studies. Further detailed analysis including feedback format/content/frequency and pharmacist skill level/experience, work-base (external/internal to recipients), will examine the impact of specific features on intervention effectiveness.

"What counts can't always be measured": a qualitative exploration of general practitioners' conceptualisation of quality for community pharmacy services

Background

The expansion of community pharmacy services is one solution to relieve pressure on general practice in the United Kingdom (UK). There is a paucity of research of general practitioners’ (GPs’) perspectives of quality of care in the community pharmacy sector.

The purpose of this study was to explore GPs’:

Conceptualisation of quality for community pharmacy services, including the management of acute (low acuity) conditions and defining indispensable aspects of the patient experience (‘always events’)

Opinions regarding whether and how to measure quality in the community pharmacy sector

Method

Semi-structured interviews were conducted with GPs in the UK. GPs were recruited using the snowballing technique and professional networks. Interviews were audio-recorded, transcribed and analysed using an interpretive approach.

Results

Interviews were completed with 20 GPs from Scotland (n = 8) and England (n = 12). Multidimensional and inter-related concepts of quality were identified; most dimensions related to patient benefit, as well as impact on GP workload or other health service provision. Interviewees cautioned that “what counts can’t always be measured”. GPs’ expectations of quality often mirrored those of their own sector, but were ambivalent about the adoption of a quality outcome framework-type approach. Pharmacist involvement was expected to ensure quality in the management of ‘acute consultations’, however, GPs lacked awareness of community pharmacy personnel type, roles and training. Interviewees’ perceptions of quality varied by pharmacy type; independent pharmacies were sometimes associated with higher quality service delivery than larger chain organisations.

Conclusions

Quality frameworks for community pharmacy services could be partly informed by GP experience and expectations, but need to be contextual to reflect differences between both settings. The importance of person-centred care, consistency and continuity was emphasised together with the need for competent personnel and privacy of interactions.

Population estimate and rate of increase of southern right whales Eubalaena australis in southeastern Australia

In Australian waters, southern right whales Eubalaena australis form 2 genetically distinct populations that have shown contrasting patterns of recovery since whaling ceased: a western population in South Australia and Western Australia and an eastern population in southeastern Australia (Tasmania, Victoria and New South Wales). Here, we provide an abundance estimate derived from a breeding female superpopulation mark-recapture model for the southeastern southern right whale population. The population comprises 268 individuals (68 breeding females) and has increased at a rate of 4.7% per annum between 1996 and 2017. There has been no significant change in the annual abundance of mother-calf pairs sighted at the only calving ground (Logans Beach in Victoria) over the last 3 decades. The total number of southern right whales (i.e. all adults and calves) using the southeastern Australian coastline has increased by 7% since 1985. Unlike the population estimate (which was restricted to breeding females sighted prior to the post-breeding southward migration), this estimate is likely to include transiting whales from the southwestern population. The theoretical population model predicts 19 breeding females at Logans Beach in 2018 and 28 in 2028; the actual number of breeding females, as of 2018, is 14. This study provides the first complete estimate of population size and rate of increase of southern right whales along the southeastern Australian coastline. This knowledge is critical for assessing population status and recovery of southern right whales in Australia. It provides a basis for monitoring persistence and responses of the population to environmental stressors.
