Identifying barriers to outpatient appointment attendance in patient groups at risk of inequity: a mixed methods study in a London NHS trust.

There is significant health inequity in the United Kingdom (U.K.), with different populations facing challenges accessing health services, which can impact health outcomes. At one London National Health Service (NHS) Trust, data showed that patients from deprived areas and minority ethnic groups had a higher likelihood of missing their first outpatient appointment. This study's objectives were to understand barriers to specific patient populations attending first outpatient appointments, explore systemic factors and assess appointment awareness. Five high-volume specialties identified as having inequitable access based on ethnicity and deprivation were selected as the study setting. Mixed methods were employed to understand barriers to outpatient attendance, including qualitative semi-structured interviews with patients and staff, observations of staff workflows and interrogation of quantitative data on appointment communication. To identify barriers, semi-structured interviews were conducted with patients who missed their appointment and were from a minority ethnic group or deprived area. Staff interviews and observations were carried out to further understand attendance barriers. Patient interview data were analysed using inductive thematic analysis to create a thematic framework and triangulated with staff data. Subthemes were mapped onto a behavioural science framework highlighting behaviours that could be targeted. Quantitative data from patient interviews were analysed to assess appointment awareness and communication. Twenty-six patients and 11 staff were interviewed, with four staff observed. Seven themes were identified as barriers - communication factors, communication methods, healthcare system, system errors, transport, appointment, and personal factors. Knowledge about appointments was an important identified behaviour, supported by eight out of 26 patients answering that they were unaware of their missed appointment. Environmental context and resources were other strongly represented behavioural factors, highlighting systemic barriers that prevent attendance. This study showed the barriers preventing patients from minority ethnic groups or living in deprived areas from attending their outpatient appointment. These barriers included communication factors, communication methods, healthcare the system, system errors, transport, appointment, and personal factors. Healthcare services should acknowledge this and work with public members from these communities to co-design solutions supporting attendance. Our work provides a basis for future intervention design, informed by behavioural science and community involvement.

Clinical impact of reducing the frequency of clozapine monitoring: controlled mirror-image cohort study.

To minimise infection during COVID-19, the clozapine haematological monitoring interval was extended from 4-weekly to 12-weekly intervals in South London and Maudsley NHS Foundation Trust. To investigate the impact of this temporary policy change on clinical and safety outcomes. All patients who received clozapine treatment with extended (12-weekly) monitoring in a large London National Health Service trust were included in a 1-year mirror-image study. A comparison group was selected with standard monitoring. The proportion of participants with mild to severe neutropenia and the proportion of participants attending the emergency department for clozapine-induced severe neutropenia treatment during the follow-up period were compared. Psychiatric hospital admission rates, clozapine dose and concomitant psychotropic medication in the 1 year before and the 1 year after extended monitoring were compared. All-cause clozapine discontinuation at 1-year follow-up was examined. Of 569 participants, 459 received clozapine with extended monitoring and 110 controls continued as normal. The total person-years were 458 in the intervention group and 109 in the control group, with a median follow-up time of 1 year in both groups. During follow-up, two participants (0.4%) recorded mild to moderate neutropenia in the intervention group and one (0.9%) in the control group. There was no difference in the incidence of haematological events between the two groups (IRR = 0.48, 95% CI 0.02-28.15, P = 0.29). All neutropenia cases in the intervention group were mild, co-occurring during COVID-19 infection. The median number of admissions per patient during the pre-mirror period remained unchanged (0, IQR = 0) during the post-mirror period. There was one death in the control group, secondary to COVID-19 infection. There was no evidence that the incidence of severe neutropenia was increased in those receiving extended monitoring.

Evaluation of the effectiveness and acceptability of the long-acting oral antipsychotic penfluridol: Illustrative case series.

In this study, we sought to determine clinical outcomes at 1 year for patients prescribed penfluridol in an inner London National Health Service Trust. Using noninterventional data, we describe the use, effectiveness and safety of this treatment modality. We retrospectively followed up 17 patients prescribed penfluridol as part of routine clinical practice. All patients took penfluridol once weekly. Of these patients, 12 (70.6%) were considered treatment resistant. The average duration of illness for this cohort was 10 years (SD = 6.7). At 1 year, nine (53%) patients remained on treatment. Median survival time was not reached at 1-year follow-up; mean time on penfluridol was 251 days (95% confidence interval (CI), 184-318). The mean number of admissions to hospital in the year following penfluridol initiation was 0.6 compared with 0.8, 1 year before initiation (p = 0.465). The median number of bed days 1 year before penfluridol initiation was 24, whereas in the year following penfluridol initiation, it was 0 (p = 0.514). Although penfluridol is unlicensed in the United Kingdom, limited data suggest that this long-acting oral therapy has the potential to be used safely and effectively for the treatment of psychotic disorders. However, more data are required to establish the place of penfluridol and other potential long-acting oral antipsychotic formulations in the treatment of psychotic disorders.

Clinical Characteristics and Predictors of Outcomes of Hospitalized Patients With Coronavirus Disease 2019 in a Multiethnic London National Health Service Trust: A Retrospective Cohort Study.

BackgroundEmerging evidence suggests ethnic minorities are disproportionately affected by coronavirus disease 2019 (COVID-19). Detailed clinical analyses of multicultural hospitalized patient cohorts remain largely undescribed.MethodsWe performed regression, survival, and cumulative competing risk analyses to evaluate factors associated with mortality in patients admitted for COVID-19 in 3 large London hospitals between 25 February and 5 April, censored as of 1 May 2020.ResultsOf 614 patients (median age, 69 [interquartile range, 25] years) and 62% male), 381 (62%) were discharged alive, 178 (29%) died, and 55 (9%) remained hospitalized at censoring. Severe hypoxemia (adjusted odds ratio [aOR], 4.25 [95% confidence interval {CI}, 2.36–7.64]), leukocytosis (aOR, 2.35 [95% CI, 1.35–4.11]), thrombocytopenia (aOR [1.01, 95% CI, 1.00–1.01], increase per 109 decrease), severe renal impairment (aOR, 5.14 [95% CI, 2.65–9.97]), and low albumin (aOR, 1.06 [95% CI, 1.02–1.09], increase per gram decrease) were associated with death. Forty percent (n = 244) were from black, Asian, and other minority ethnic (BAME) groups, 38% (n = 235) were white, and ethnicity was unknown for 22% (n = 135). BAME patients were younger and had fewer comorbidities. Although the unadjusted odds of death did not differ by ethnicity, when adjusting for age, sex, and comorbidities, black patients were at higher odds of death compared to whites (aOR, 1.69 [95% CI, 1.00–2.86]). This association was stronger when further adjusting for admission severity (aOR, 1.85 [95% CI, 1.06–3.24]).ConclusionsBAME patients were overrepresented in our cohort; when accounting for demographic and clinical profile of admission, black patients were at increased odds of death. Further research is needed into biologic drivers of differences in COVID-19 outcomes by ethnicity.

Assertive outreach treatment versus care as usual for the treatment of high-need, high-cost alcohol related frequent attenders: study protocol for a randomised controlled trial

BackgroundAlcohol-related hospital admissions have doubled in the last ten years to > 1.2 m per year in England. High-need, high-cost (HNHC) alcohol-related frequent attenders (ARFA) are a relatively small subgroup of patients, having multiple admissions or attendances from alcohol during a short time period. This trial aims to test the effectiveness of an assertive outreach treatment (AOT) approach in improving clinical outcomes for ARFA, and reducing resource use in the acute setting.MethodsOne hundred and sixty ARFA patients will be recruited and following baseline assessment, randomly assigned to AOT plus care as usual (CAU) or CAU alone in equal numbers. Baseline assessment includes alcohol consumption and related problems, physical and mental health comorbidity and health and social care service use in the previous 6 months using standard validated tools, plus a measure of resource use. Follow-up assessments at 6 and 12 months after randomization includes the same tools as baseline plus standard measure of patient satisfaction. Outcomes for CAU + AOT and CAU at 6 and 12 months will be compared, controlling for pre-specified baseline measures. Primary outcome will be percentage of days abstinent at 12 months. Secondary outcomes include emergency department (ED) attendance, number and length of hospital admissions, alcohol consumption, alcohol-related problems, other health service use, mental and physical comorbidity 6 and 12 months post intervention. Health economic analysis will estimate the economic impact of AOT from health, social care and societal perspectives and explore cost-effectiveness in terms of quality adjusted life years and alcohol consumption at 12-month follow-up.DiscussionAOT models piloted with alcohol dependent patients have demonstrated significant reductions in alcohol consumption and use of unplanned National Health Service (NHS) care, with increased engagement with alcohol treatment services, compared with patients receiving CAU. While AOT interventions are costlier per case than current standard care in the UK, the rationale for targeting HNHC ARFAs is because of their disproportionate contribution to overall alcohol burden on the NHS. No previous studies have evaluated the clinical and cost-effectiveness of AOT for HNHC ARFAs: this randomized controlled trial (RCT) targeting ARFAs across five South London NHS Trusts is the first.Trial registrationInternational standard randomized controlled trial number (ISRCTN) registry: ISRCTN67000214, retrospectively registered 26/11/2016.

Adverse life experiences and triggers for self-harm in young people aged 12–26 years in inner south London: a retrospective observational study

BackgroundThe prevalence of self-harm among children and young people in the UK is increasing, with few accessing formal support. Drivers of self-harm remain poorly understood, and evidence-based opportunities to intervene are scarce. We aimed to identify factors associated with self-harm in young people to inform local action. MethodsIn this retrospective, observational study, we identified 196 residents of the south London Borough of Lambeth, aged 12–26 years, presenting to two emergency departments for injuries related to self-harm in the 2015–16 financial year (April 1, 2015, to March 31, 2016). A pragmatic sample size of 100 was selected via computer randomisation for further analysis. Electronic mental health records were retrospectively analysed using a data collection protocol that was validated with researchers before data collection. Demographics and psychiatric history were obtained from pre-coded databases linking electronic mental health records and Hospital Episode Statistics data on emergency department attendance for self-harm. Presentation details and social risk factors were derived from assessment of case notes pertaining to the 2 weeks after first presentation; we noted any risk factors that had been positively recorded. Data relating to the individual's first presentation within the study period were used; subsequent attendances were not included in the sample. We analysed the data using descriptive statistics. Ethical approval for data access and linkage was granted by the Oxford Research Ethics Committee C (18/SC/0372), Clinical Records Interactive Search system Oversight Committee (project numbers 14–026 and 19–004), and the National Health Service (NHS) Health Research Authority Confidentiality Advisory Group (reference ECC 3–04(f)/2011). This study received approval as an audit project through Southwark Operational Directorate in the South London and Maudsley Foundation NHS Trust. Findings48 (48%) of the 100 selected participants had documented experience of psychological trauma, including exposure to violence. 18 (18%) lived in unstable accommodation, and 20 (20%) were known to social services. Difficulties at home (16 [16%]) and stress relating to housing, school, or financial pressures (13 [13%]) were common documented triggers for the self-harm episode at presentation. Peer influence was rarely noted, although 27 (27%) had recorded experience of bullying. InterpretationAdverse life experiences were prevalent and align with wider population prevalence estimates. Common triggers for self-harm relate to home and school environment and wider socioeconomic stressors, supporting the link between wider determinants of health and self-harm, and contributing to the case for public health action. Risk factors and triggers identified provide potential areas for additional targeted support to prevent development or escalation of self-harm behaviours.

One stop multidisciplinary pain clinic for survivors of torture.

Bianca Kuehler and Susan Childs speak to Jade Parker, Commissioning Editor: Dr Bianca Kuehler initially qualified in Germany as an anesthetist in 1993 and is on the specialist register in the UK. After moving to the UK she obtained a Diploma in Occupational Health to supplement the understanding and implication of chronic pain on the work environment. She is very interested in multidisciplinary approaches in treatment of chronic and acute pain patients and, therefore, working closely with Dr Childs opened a plethora of opportunities to develop new services including a fibromyalgia clinic and a specialist clinic for patients who are survivors of torture. Dr Susan Childs is an experienced clinical psychologist who has worked within health psychology and mental health since 1997. Her particular area of expertise is chronic pain. Alongside this, she has developed expertise in the assessment and treatment of a wide range of psychological issues. She has more recently focused upon co-developing services alongside her medical lead and co-facilitator, Dr Bianca Kuehler, for patients who are survivors of torture. Susan leads therapy services at a major London National Health Service trust in a Consultant capacity and supports a team of physicians, surgeons, pain specialist physicians, physiotherapists and clinical specialist nurses.

Human trafficking and severe mental illness: an economic analysis of survivors' use of psychiatric services.

BackgroundPrevious studies have found a high prevalence of depression and post-traumatic stress disorder (PTSD) among survivors of human trafficking. European countries are required to assist trafficked people in their psychological recovery, but there are no rigorous data on the costs of doing so. The objectives of this study were to quantify the use of secondary mental health services by survivors of human trafficking; to estimate the cost of survivors’ use of secondary mental health services provided by the UK National Health Service (NHS); and to identify factors that predict higher costs of mental health service provision.MethodsHistorical cohort study of psychiatric patients who had experienced human trafficking. The South London and Maudsley NHS Trust (SLaM) Biomedical Research Centre Case Register Interactive Search (CRIS) database was used to identify anonymised full patient records of patients who had experienced human trafficking and who had accessed SLaM mental health services between 2007 and 2012. Data were extracted on socio-demographic and trafficking characteristics and contacts with mental health services. Total costs were calculated by multiplying each resource use item by an appropriate unit cost. Factors that predicted high mental health service costs were analysed using regression models.ResultsOne hundred nineteen patients were included in the analysis. Mean total mental health service costs per patient were £27,293 (sd 80,985) and mean duration of contact with services was 1490 (sd 757) days (approximately 4 years). Regression analysis showed that higher costs were associated with diagnosis of psychotic disorder (p < 0.001) and experiences of pre-trafficking violence (p = 0.06). Patients diagnosed with psychotic disorders cost approximately £32,635 more than patients with non-psychotic disorders/psychological distress but no formal diagnosis and patients whose clinical notes documented pre-trafficking violence cost £88,633 more than patients for whom pre-trafficking violence was not documented.ConclusionsTrafficked patients’ use of mental health services – and the cost of providing care – is highly variable, but patients with psychotic disorders and with experiences of pre-trafficking violence are likely to require more intensive support. Evidence is needed on the effectiveness of interventions to promote the recovery of survivors of human trafficking.

In-patient rehabilitation: clinical outcomes and cost implications.

Aims and method A retrospective evaluation was undertaken of the clinical and economic effectiveness of three in-patient rehabilitation units across one London National Health Service trust. Information on admission days and costs 2 years before and 2 years after the rehabilitation placement, length of rehabilitation placement and the discharge pathway was collected on 22 service users.Results There were statistically significant reductions in hospital admission days in the 2 years following rehabilitation compared with the 2 years before, further reflected in significantly lower bed costs. Longer length of rehabilitation placement was correlated with fewer admission days after the placement. A substantial proportion of the sample went into more independent living, some with no further admissions at follow-up.Clinical implications The findings suggest that in-patient rehabilitation is both clinically and cost effective: if benefits are sustained they will offset the cost of the rehabilitation placement.

Never ever? Characteristics, outcomes and motivations of patients who abscond or escape: A 5-year review of escapes and absconds from two medium and low secure forensic units.

Absconds and escapes by psychiatric patients from secure forensic psychiatric settings create public anxiety and are poorly understood. To describe secure hospital patients who escape from within the secure perimeter or abscond, and test for differences between these groups. Escapes and absconds between 2008 and 2012 from the medium and low secure forensic psychiatric inpatient units of two London National Health Service Trusts were identified through the Trusts' databases. Demographic, offending, mental health and incident data were extracted from records for each. Seventy-seven incidents, involving 54 patients, were identified over the five years. These were 13 escapes involving 12 patients, representing a rate of 0.04 per 1000 bed days, and 64 absconds involving 42 patients, a rate of 0.26 per 1000 bed days; 15 (28%) patients were absent without leave more than once. Over half of the patients came back voluntarily within 24 hours of leaving. Over 50% of them had drunk alcohol or taken drugs while away from the unit. Escapees were more likely to be transferred prisoners and to have planned their escape, less likely to return to the unit voluntarily and away longer than patients who absconded. Offending was rare during unauthorised leave--just three offences among the 77 incidents; self-harm was more likely. Motives for absconding included: wanting freedom or drink or drugs, family worries and/or dissatisfaction with aspects of treatment. Escapes or absconding from secure healthcare units have different characteristics, but may best be prevented by convergent strategies. Relational security is likely to be as important for foiling plans for the former as it is for reducing boredom, building strong family support and managing substance misuse in the latter.

The effect of an educational intervention on junior doctors’ knowledge and practice in detecting and managing elder abuse

Elder abuse is often unreported, undetected, and underestimated by professionals. For the first time, we report the effectiveness of an educational elder abuse intervention over three months and its impact on professionals' practice. Forty trainee psychiatrists in two London National Health Service trusts completed the KAMA (Knowledge and Management of Elder Abuse) and CSQ (Caregiver Scenario Questionnaire) measuring knowledge about managing and detecting elder abuse, before and immediately after a brief group education session. We asked how often they considered, asked about, detected, and managed elder abuse and their confidence in doing so, at baseline and three months post-intervention. Compared with baseline, participants scored higher on the KAMA (paired t = 3.4, p = 0.002), and identified more definitely abusive (t = 3.0, p = 0.003) and possibly abusive (t = 2.1, p = 0.043) items immediately post-intervention. At three-month follow up, 24 (60%) participants reported higher confidence in managing abuse (Wilcoxon signed ranks test z = 3.7, p < 0.001) and considered it more frequently (z = 2.8, p = 0.006), but did not ask older people and their carers about abuse more frequently (z = 1.2, p = 0.24). Two (5%, 95% confidence interval 2%-17%) participants detected abuse in the three months before the intervention, compared with 2 (8%, 2%-26%) in the same period afterward. This brief educational intervention increased trainee psychiatrists' knowledge and vigilance for abuse immediately and after three months. They remained reluctant to ask about abuse for reasons including fear of causing offence or harming the therapeutic relationship and being unsure how to ask people with dementia. We postulate that changing doctors' behavior may require a more complex intervention, focusing on communication skills.

Hospital treatment and management in relapse of schizophrenia in the UK: associated costs

Aims and methodRelapse in schizophrenia carries a heavy burden. This study aimed to describe the characteristics of patients admitted to hospital for relapse and to explore the treatment, length of stay and associated in-patient costs. The sample comprised individuals discharged from a London National Health Service trust following a relapse of schizophrenia. The costs of hospital treatment were obtained by applying referenced unit costs.ResultsThe cohort comprised 71 patients. Treatment non-adherence was implicated in 76% of relapses. Mean length of hospital stay was 138.9 days (range 1 week-1.8 years). Mean admission cost was £25 852 (range £1270-120 000). Over 97% of costs were hospital costs and less than 3% drug costs.Clinical implicationsHospital treatment for relapse of schizophrenia carries a considerable economic burden, as shown in this study. Treatment non-adherence is a significant factor contributing to relapse.

The Effect of Kinesiotape on Function, Pain, and Motoneuronal Excitability in Healthy People and People With Achilles Tendinopathy

To investigate the effect of kinesiotape on hop distance, pain, and motoneuronal excitability in healthy people and people with Achilles tendinopathy (AT). Within-subject design. An academic health science center, which is an acute London National Health Service trust. With ethical approval and informed consent, a convenience sample of 26 healthy people and 29 people with AT were recruited. Seven participants were lost after functional testing, leaving 24 participants in each group. Kinesiotape applied over the Achilles tendon. The single-leg hop test and visual analog scale were measured with and without the tape. Using the Hoffman (H) reflex, change in motoneuronal excitability of calf muscles was measured before tape application, with the tape on and after its removal. There were no changes to hop distance when tape was applied (P = 0.55). Additionally, there were no changes to pain (P = 0.74). The H reflex amplitude of soleus and gastrocnemius increased in the healthy group after its removal (P = 0.01 and P = 0.03, respectively), whereas the H reflex remained unchanged in people with AT (P = 0.43 and 0.16, respectively). Calf muscles were facilitated by kinesiotape in healthy participants. Despite this, there was no change to hop distance. Kinesiotape had no effect on hop distance, pain, or motoneuronal excitability in people with AT. These results do not support the use of kinesiotape applied in this way for this condition.

Antenatal screening and prevalence of infection: surveillance in London, 2000-2007

In the United Kingdom (UK), it is recommended to universally offer antenatal infection screening for human immunodeficiency virus (HIV), hepatitis B and syphilis infections, and susceptibility to rubella for the benefit of the mother and to reduce vertical transmission of infection. This paper describes the surveillance of antenatal infection including uptake of screening, and the results of testing in pregnant women in London between 2000 and 2007. Antenatal screening coordinators in liaison with midwifery heads and microbiologists at all thirty London National Health Service (NHS) Trust maternity units supplied quarterly data on the number of pregnant women booked for antenatal care, tests done, and tests results. The overall estimated uptake of screening increased since 2000 and reached 95.6% for HIV, 96.5% for syphilis, 96.2% for hepatitis B and 97% for rubella susceptibility by the second half of 2007. There is considerable variation in the performance between NHS Trusts. The overall estimated prevalence of HIV infection was 3.4/1,000 women (ranging from <1/1,000 to 10/1,000 across Trusts), of hepatitis B (HBsAg-positive) was 11.3/1,000 (2.6/1,000- 23.9/1,000), of syphilis was 4.4/1,000 (<1/1,000-16.3/1,000) and of rubella susceptibility was 39.3/1,000 (19-103/1,000). Antenatal infection screening has improved and there has been some success in implementation of national policy. However, screening uptake and prevalence of infection vary considerably across London NHS Trusts and some women are evidently disadvantaged. Improvements in information systems should help local partners to focus their interventions in those Trusts where work is still needed to increase testing as well as the capacity to monitor the uptake of screening.
