Anaesthetic management of a three-month-old baby for cervical limited dorsal myeloschisis repair using propofol and alfentanil infusions guided by pharmacokinetic simulation software: A case report

We present an uncommon case of limited dorsal myeloschisis in a 3-month-old infant requiring repair guided by intraoperative neuromonitoring (IONM) and therefore avoidance of volatile anaesthetic agents. The case presented challenges in positioning, airway management, a lack of age appropriate pharmacokinetic models in target-controlled infusion (TCI) syringe pumps and unavailability of remifentanil, considered to be an essential drug in this setting. We overcame these challenges using manually controlled infusions of propofol and alfentanil guided by pharmacokinetic simulation software (Stelsim).

Search for Subsolar Mass Ultracompact Binaries in Advanced LIGO's Second Observing Run

We present a search for subsolar mass ultracompact objects in data obtained during Advanced LIGO's second observing run. In contrast to a previous search of Advanced LIGO data from the first observing run, this search includes the effects of component spin on the gravitational waveform. We identify no viable gravitational-wave candidates consistent with subsolar mass ultracompact binaries with at least one component between 0.2  M_{⊙}-1.0  M_{⊙}. We use the null result to constrain the binary merger rate of (0.2  M_{⊙}, 0.2  M_{⊙}) binaries to be less than 3.7×10^{5}  Gpc^{-3} yr^{-1} and the binary merger rate of (1.0  M_{⊙}, 1.0  M_{⊙}) binaries to be less than 5.2×10^{3}  Gpc^{-3} yr^{-1}. Subsolar mass ultracompact objects are not expected to form via known stellar evolution channels, though it has been suggested that primordial density fluctuations or particle dark matter with cooling mechanisms and/or nuclear interactions could form black holes with subsolar masses. Assuming a particular primordial black hole (PBH) formation model, we constrain a population of merging 0.2  M_{⊙} black holes to account for less than 16% of the dark matter density and a population of merging 1.0  M_{⊙} black holes to account for less than 2% of the dark matter density. We discuss how constraints on the merger rate and dark matter fraction may be extended to arbitrary black hole population models that predict subsolar mass binaries.

Assessment of need and practice for assistive technology and telecare for people with dementia-The ATTILA (Assistive Technology and Telecare to maintain Independent Living At home for people with dementia) trial

Introduction

The objective of this study was to define current assistive technology and telecare (ATT) practice for people with dementia living at home.

Methods

This is a randomized controlled trial (N = 495) of ATT assessment and ATT installation intervention, compared with control (restricted ATT package). ATT assessment and installation data were collected. Qualitative work identified value networks delivering ATT, established an ATT assessment standard.

Results

ATT was delivered by public and not-for-profit telecare networks. ATT assessments showed 52% fidelity to the ATT assessment standard. Areas of assessment most frequently leading to identifying ATT need were daily activities (93%), memory (89%), and problem-solving (83%). ATT needs and recommendations were weakly correlated (τ = 0.242; P < .000), with ATT recommendations and installations moderately correlated (τ = −0.470; P < .000). Half (53%) of recommended technology was not installed. Safety concerns motivated 38% of installations.

Discussion

Assessment recommendations were routinely disregarded at the point of installation. ATT was commonly recommended for safety and seldom for supporting leisure.

Depression in migrant workers and nationals of Qatar: An exploratory cross-cultural study

BACKGROUND

The aim of this study was to compare the prevalence of depressive symptoms among migrants and non-migrants living in Qatar and identify variables associated with depressive symptomology in these groups, including culture of origin, time living in country and perceived quality of life. In addition, we tested if the latter two variables moderated the effect of culture of origin on depressive symptomology in the migrant groups.

SUBJECT AND METHODS

A telephone survey of a probability-based sample of 2,520 participants was conducted in February 2016. The sample was divided into three groups based on nationality and income: labour migrants (LMs), white-collar migrants (WCMs) and non-migrants or Qatari nationals (QNs). Participants completed the Whooley two-question test for depression.

RESULTS

The odds of depression were significantly increased in LMs (OR = 3.31, 95% CI = 2.36-4.65) and WCMs (OR = 1.40, 95% CI = 1.04-1.90) compared with non-migrants. Among LMs, having a problem with current employer in the last 3 months was also associated with depressive symptoms (OR = 2.10, 95% CI = 1.14-3.84). Culture of origin was significantly associated with depressive symptoms including South Asians (OR = 3.12, p < .001), East Asians (OR = 0.52, p = .013) and Westerners (OR = 0.45, p = .044) relative to Arabs. LM status remained strongly associated with depressive symptoms independent of culture of origin (OR = 2.02, p < .001).

CONCLUSION

Perceived quality of life, but not length of stay, appears to be an important variable in explaining differences in symptoms between some cultural groups. Findings from this study highlight the importance of the context of migration and culture of origin as potential determinants of depressive symptomology in the host country.

Association between subthreshold depression and self-care behaviour in people with type 2 diabetes: a protocol for systematic review of observational studies

BACKGROUND

Depression is a common comorbidity in type 2 diabetes. Studies have consistently shown that major depression is associated with decreased diabetic self-care behaviour. People with subthreshold depression experience greater functional impairment, have a poorer quality of life and use health services more than those without depressive symptoms. Although subthreshold depression impacts self-care behaviour, the relationship between subthreshold depression and diabetes self-care behaviour has not been systematically reviewed. The objective of this systematic review is to determine the association between subthreshold depression and self-care behaviour in adults with type 2 diabetes.

METHODS

This protocol will follow the guideline of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2015 (PRISMA-P-2015). A systematic search of literature will be conducted for observational studies reporting the association between subthreshold depression and self-care behaviour in adults aged 18 years or over and diagnosed with type 2 diabetes. Electronic databases including MEDLINE, EMBASE, PsycINFO, Emcare and CINAHL will be searched using predefined search terms. Title and abstract, full-text screening and data extraction of identified articles will be done by two reviewers independently. Discrepancies will be resolved by a third author. The methodological quality of the included studies will be assessed using The Joanna Briggs Institute (JBI) risk of bias tools. The review results will be presented in the form of narrative synthesis, and if sufficient studies are available and variability among the studies is low, a random effects meta-analysis will be done to quantify the result.

DISCUSSION

This review will synthesise evidence on the association between subthreshold depression and self-care behaviour in type 2 diabetic adults. The findings will be useful to researchers and policymakers to determine the most effective approach to overall diabetes management. The review will also identify research gaps in the current literature and provide direction for future research in this area of study.

Confirmation that somatic mutations of beta-2 microglobulin correlate with a lack of recurrence in a subset of stage II mismatch repair deficient colorectal cancers from the QUASAR trial

Aims

Beta2‐microglobulin (B2M) forms part of the HLA class I complex and plays a role in metastatic biology. B2M mutations occur frequently in mismatch repair‐deficient colorectal cancer (dMMR CRC), with limited data suggesting they may protect against recurrence. Our experimental study tested this hypothesis by investigating B2M mutation status and B2M protein expression and recurrence in patients in the stage II QUASAR clinical trial.

Methods and results

Sanger sequencing was performed for the three coding exons of B2M on 121 dMMR and a subsample of 108 pMMR tumours; 52 with recurrence and 56 without. B2M protein expression was assessed by immunohistochemistry. Mutation status and protein expression were correlated with recurrence and compared to proficient mismatch repair (pMMR) CRCs. Deleterious B2M mutations were detected in 39 of 121 (32%) dMMR tumours. Five contained missense B2M‐variants of unknown significance, so were excluded from further analyses. With median follow‐up of 7.4 years, none of the 39 B2M‐mutant tumours recurred, compared with 14 of 77 (18%) B2M‐wild‐type tumours (P = 0.005); six at local and eight at distant sites. Sensitivity and specificity of IHC in detecting B2M mutations was 87 and 71%, respectively. Significantly (P < 0.0001) fewer (three of 104, 2.9%) of the 108 pMMR CRCs demonstrated deleterious B2M mutations. One pMMR tumour, containing a frameshift mutation, later recurred.

Conclusion

B2M mutations were detected in nearly one‐third of dMMR cancers, none of which recurred. B2M mutation status has potential clinical utility as a prognostic biomarker in stage II dMMR CRC. The mechanism of protection against recurrence and whether this protection extends to stage III disease remains unclear.

Therapeutic Dancing for Frail Older People in Residential Aged Care: A Thematic Analysis of Barriers and Facilitators to Implementation

Background

Adults who live in residential aged care can have reduced participation in physical activities and sit for prolonged periods. Therapeutic dancing aims to optimize movement, creative expression, well-being, and social interaction.

Objectives

To investigate the benefits, challenges, and facilitators to implementing therapeutic dancing in residential aged care.

Methods

Thematic analysis of semistructured interviews of residential aged care staff and therapists. Interviews were digitally audio-recorded and thematically analyzed. Findings: Four main themes were identified: (a) despite frailty, dancing classes afforded motor and nonmotor benefits, (b) music and dance genre selections were key to success, (c) the skills of the dance instructor were associated with successful outcomes, and (d) there were modifiable and nonmodifiable facilitators and barriers to implementation.

Conclusion

Enablers included support from management, resident supervision, age-appropriate music with a strong rhythmical beat, and a dance instructor skilled in comprehensive care. Barriers included multimorbidity, frailty, severe cognitive impairment, and funding.

Amisulpride for very late-onset schizophrenia-like psychosis: the ATLAS three-arm RCT

BACKGROUND

Very late-onset (aged ≥ 60 years) schizophrenia-like psychosis (VLOSLP) occurs frequently but no placebo-controlled, randomised trials have assessed the efficacy or risks of antipsychotic treatment. Most patients are not prescribed treatment.

OBJECTIVES

The study investigated whether or not low-dose amisulpride is superior to placebo in reducing psychosis symptoms over 12 weeks and if any benefit is maintained by continuing treatment thereafter. Treatment safety and cost-effectiveness were also investigated.

DESIGN

Three-arm, parallel-group, placebo-controlled, double-blind, randomised controlled trial. Participants who received at least one dose of study treatment were included in the intention-to-treat analyses.

SETTING

Secondary care specialist old age psychiatry services in 25 NHS mental health trusts in England and Scotland.

PARTICIPANTS

Patients meeting diagnostic criteria for VLOSLP and scoring > 30 points on the Brief Psychiatric Rating Scale (BPRS).

INTERVENTION

Participants were randomly assigned to three arms in a two-stage trial: (1) 100 mg of amisulpride in both stages, (2) amisulpride then placebo and (3) placebo then amisulpride. Treatment duration was 12 weeks in stage 1 and 24 weeks (later reduced to 12) in stage 2. Participants, investigators and outcome assessors were blind to treatment allocation.

MAIN OUTCOME MEASURES

Primary outcomes were psychosis symptoms assessed by the BPRS and trial treatment discontinuation for non-efficacy. Secondary outcomes were extrapyramidal symptoms measured with the Simpson-Angus Scale, quality of life measured with the World Health Organization's quality-of-life scale, and cost-effectiveness measured with NHS, social care and carer work loss costs and EuroQol-5 Dimensions.

RESULTS

A total of 101 participants were randomised. Ninety-two (91%) participants took the trial medication, 59 (64%) completed stage 1 and 33 (56%) completed stage 2 treatment. Despite suboptimal compliance, improvements in BPRS scores at 12 weeks were 7.7 points (95% CI 3.8 to 11.5 points) greater with amisulpride than with placebo (11.9 vs. 4.2 points; p = 0.0002). In stage 2, BPRS scores improved by 1.1 point in those who continued with amisulpride but deteriorated by 5.2 points in those who switched from amisulpride to placebo, a difference of 6.3 points (95% CI 0.9 to 11.7 points; p = 0.024). Fewer participants allocated to the amisulpride group stopped treatment because of non-efficacy in stages 1 (p = 0.01) and 2 (p = 0.031). The number of patients stopping because of extrapyramidal symptoms and other side effects did not differ significantly between groups. Amisulpride treatment in the base-case analyses was associated with non-significant reductions in combined NHS, social care and unpaid carer costs and non-significant reductions in quality-adjusted life-years (QALYs) in both stages. Including patients who were intensive users of inpatient services in sensitivity analyses did not change the QALY result but resulted in placebo dominance in stage 1 and significant reductions in NHS/social care (95% CI -£8923 to -£122) and societal costs (95% CI -£8985 to -£153) for those continuing with amisulpride.

LIMITATIONS

The original recruitment target of 300 participants was not achieved and compliance with trial medication was highly variable.

CONCLUSIONS

Low-dose amisulpride is effective and well tolerated as a treatment for VLOSLP, with benefits maintained by prolonging treatment. Potential adverse events include clinically significant extrapyramidal symptoms and falls.

FUTURE WORK

Trials should examine the longer-term effectiveness and safety of antipsychotic treatment in this patient group, and assess interventions to improve their appreciation of potential benefits of antipsychotic treatment and compliance with prescribed medication.

Partial ablation versus radical prostatectomy in intermediate-risk prostate cancer: the PART feasibility RCT

BACKGROUND

Prostate cancer (PCa) is the most common cancer in men in the UK. Patients with intermediate-risk, clinically localised disease are offered radical treatments such as surgery or radiotherapy, which can result in severe side effects. A number of alternative partial ablation (PA) technologies that may reduce treatment burden are available; however the comparative effectiveness of these techniques has never been evaluated in a randomised controlled trial (RCT).

OBJECTIVES

To assess the feasibility of a RCT of PA using high-intensity focused ultrasound (HIFU) versus radical prostatectomy (RP) for intermediate-risk PCa and to test and optimise methods of data capture.

DESIGN

We carried out a prospective, multicentre, open-label feasibility study to inform the design and conduct of a future RCT, involving a QuinteT Recruitment Intervention (QRI) to understand barriers to participation.

SETTING

Five NHS hospitals in England.

PARTICIPANTS

Men with unilateral, intermediate-risk, clinically localised PCa.

INTERVENTIONS

Radical prostatectomy compared with HIFU.

PRIMARY OUTCOME MEASURE

The randomisation of 80 men.

SECONDARY OUTCOME MEASURES

Findings of the QRI and assessment of data capture methods.

RESULTS

Eighty-seven patients consented to participate by 31 March 2017 and 82 men were randomised by 4 May 2017 (41 men to the RP arm and 41 to the HIFU arm). The QRI was conducted in two iterative phases: phase I identified a number of barriers to recruitment, including organisational challenges, lack of recruiter equipoise and difficulties communicating with patients about the study, and phase II comprised the development and delivery of tailored strategies to optimise recruitment, including group training, individual feedback and 'tips' documents. At the time of data extraction, on 10 October 2017, treatment data were available for 71 patients. Patient characteristics were similar at baseline and the rate of return of all clinical case report forms (CRFs) was 95%; the return rate of the patient-reported outcome measures (PROMs) questionnaire pack was 90.5%. Centres with specific long-standing expertise in offering HIFU as a routine NHS treatment option had lower recruitment rates (Basingstoke and Southampton) - with University College Hospital failing to enrol any participants - than centres offering HIFU in the trial context only.

CONCLUSIONS

Randomisation of men to a RCT comparing PA with radical treatments of the prostate is feasible. The QRI provided insights into the complexities of recruiting to this surgical trial and has highlighted a number of key lessons that are likely to be important if the study progresses to a main trial. A full RCT comparing clinical effectiveness, cost-effectiveness and quality-of-life outcomes between radical treatments and PA is now warranted.

FUTURE WORK

Men recruited to the feasibility study will be followed up for 36 months in accordance with the protocol. We will design a full RCT, taking into account the lessons learnt from this study. CRFs will be streamlined, and the length and frequency of PROMs and resource use diaries will be reviewed to reduce the burden on patients and research nurses and to optimise data completeness.

Routine low-dose continuous or nocturnal oxygen for people with acute stroke: three-arm Stroke Oxygen Supplementation RCT

BACKGROUND

Stroke is a major cause of death and disability worldwide. Hypoxia is common after stroke and is associated with worse outcomes. Oxygen supplementation could prevent hypoxia and secondary brain damage.

OBJECTIVES

(1) To assess whether or not routine low-dose oxygen supplementation in patients with acute stroke improves outcome compared with no oxygen; and (2) to assess whether or not oxygen given at night only, when oxygen saturation is most likely to be low, is more effective than continuous supplementation.

DESIGN

Multicentre, prospective, randomised, open, blinded-end point trial.

SETTING

Secondary care hospitals with acute stroke wards.

PARTICIPANTS

Adult stroke patients within 24 hours of hospital admission and 48 hours of stroke onset, without definite indications for or contraindications to oxygen or a life-threatening condition other than stroke.

INTERVENTIONS

Allocated by web-based minimised randomisation to: (1) continuous oxygen: oxygen via nasal cannula continuously (day and night) for 72 hours after randomisation at a flow rate of 3 l/minute if baseline oxygen saturation was ≤ 93% or 2 l/minute if > 93%; (2) nocturnal oxygen: oxygen via nasal cannula overnight (21:00-07:00) for three consecutive nights. The flow rate was the same as the continuous oxygen group; and (3) control: no routine oxygen supplementation unless required for reasons other than stroke.

MAIN OUTCOME MEASURES

Primary outcome: disability assessed by the modified Rankin Scale (mRS) at 3 months by postal questionnaire (participant aware, assessor blinded). Secondary outcomes at 7 days: neurological improvement, National Institutes of Health Stroke Scale (NIHSS), mortality, and the highest and lowest oxygen saturations within the first 72 hours. Secondary outcomes at 3, 6, and 12 months: mortality, independence, current living arrangements, Barthel Index, quality of life (European Quality of Life-5 Dimensions, three levels) and Nottingham Extended Activities of Daily Living scale by postal questionnaire.

RESULTS

In total, 8003 patients were recruited between 24 April 2008 and 17 June 2013 from 136 hospitals in the UK [continuous, n = 2668; nocturnal, n = 2667; control, n = 2668; mean age 72 years (standard deviation 13 years); 4398 (55%) males]. All prognostic factors and baseline characteristics were well matched across the groups. Eighty-two per cent had ischaemic strokes. At baseline the median Glasgow Coma Scale score was 15 (interquartile range 15-15) and the mean and median NIHSS scores were 7 and 5 (range 0-34), respectively. The mean oxygen saturation at randomisation was 96.6% in the continuous and nocturnal oxygen groups and 96.7% in the control group. Primary outcome: oxygen supplementation did not reduce disability in either the continuous or the nocturnal oxygen groups. The unadjusted odds ratio for a better outcome (lower mRS) was 0.97 [95% confidence interval (CI) 0.89 to 1.05; p = 0.5] for the combined oxygen groups (both continuous and nocturnal together) (n = 5152) versus the control (n = 2567) and 1.03 (95% CI 0.93 to 1.13; p = 0.6) for continuous versus nocturnal oxygen. Secondary outcomes: oxygen supplementation significantly increased oxygen saturation, but did not affect any of the other secondary outcomes.

LIMITATIONS

Severely hypoxic patients were not included.

CONCLUSIONS

Routine low-dose oxygen supplementation in stroke patients who are not severely hypoxic is safe, but does not improve outcome after stroke.

FUTURE WORK

To investigate the causes of hypoxia and develop methods of prevention.

Increasing the dose intensity of chemotherapy by more frequent administration or sequential scheduling: a patient-level meta-analysis of 37 298 women with early breast cancer in 26 randomised trials

BACKGROUND

Increasing the dose intensity of cytotoxic therapy by shortening the intervals between cycles, or by giving individual drugs sequentially at full dose rather than in lower-dose concurrent treatment schedules, might enhance efficacy.

METHODS

To clarify the relative benefits and risks of dose-intense and standard-schedule chemotherapy in early breast cancer, we did an individual patient-level meta-analysis of trials comparing 2-weekly versus standard 3-weekly schedules, and of trials comparing sequential versus concurrent administration of anthracycline and taxane chemotherapy. The primary outcomes were recurrence and breast cancer mortality. Standard intention-to-treat log-rank analyses, stratified by age, nodal status, and trial, yielded dose-intense versus standard-schedule first-event rate ratios (RRs).

FINDINGS

Individual patient data were provided for 26 of 33 relevant trials identified, comprising 37 298 (93%) of 40 070 women randomised. Most women were aged younger than 70 years and had node-positive disease. Total cytotoxic drug usage was broadly comparable in the two treatment arms; colony-stimulating factor was generally used in the more dose-intense arm. Combining data from all 26 trials, fewer breast cancer recurrences were seen with dose-intense than with standard-schedule chemotherapy (10-year recurrence risk 28·0% vs 31·4%; RR 0·86, 95% CI 0·82-0·89; p<0·0001). 10-year breast cancer mortality was similarly reduced (18·9% vs 21·3%; RR 0·87, 95% CI 0·83-0·92; p<0·0001), as was all-cause mortality (22·1% vs 24·8%; RR 0·87, 95% CI 0·83-0·91; p<0·0001). Death without recurrence was, if anything, lower with dose-intense than with standard-schedule chemotherapy (10-year risk 4·1% vs 4·6%; RR 0·88, 95% CI 0·78-0·99; p=0·034). Recurrence reductions were similar in the seven trials (n=10 004) that compared 2-weekly chemotherapy with the same chemotherapy given 3-weekly (10-year risk 24·0% vs 28·3%; RR 0·83, 95% CI 0·76-0·91; p<0·0001), in the six trials (n=11 028) of sequential versus concurrent anthracycline plus taxane chemotherapy (28·1% vs 31·3%; RR 0·87, 95% CI 0·80-0·94; p=0·0006), and in the six trials (n=6532) testing both shorter intervals and sequential administration (30·4% vs 35·0%; RR 0·82, 95% CI 0·74-0·90; p<0·0001). The proportional reductions in recurrence with dose-intense chemotherapy were similar and highly significant (p<0·0001) in oestrogen receptor (ER)-positive and ER-negative disease and did not differ significantly by other patient or tumour characteristics.

INTERPRETATION

Increasing the dose intensity of adjuvant chemotherapy by shortening the interval between treatment cycles, or by giving individual drugs sequentially rather than giving the same drugs concurrently, moderately reduces the 10-year risk of recurrence and death from breast cancer without increasing mortality from other causes.

Crisis resolution teams for people experiencing mental health crises: the CORE mixed-methods research programme including two RCTs

Background

Crisis resolution teams (CRTs) seek to avert hospital admissions by providing intensive home treatment for people experiencing a mental health crisis. The CRT model has not been highly specified. CRT care is often experienced as ending abruptly and relapse rates following CRT discharge are high.

Aims

The aims of CORE (Crisis resolution team Optimisation and RElapse prevention) workstream 1 were to specify a model of best practice for CRTs, develop a measure to assess adherence to this model and evaluate service improvement resources to help CRTs implement the model with high fidelity. The aim of CORE workstream 2 was to evaluate a peer-provided self-management programme aimed at reducing relapse following CRT support.

Methods

Workstream 1 was based on a systematic review, national CRT manager survey and stakeholder qualitative interviews to develop a CRT fidelity scale through a concept mapping process with stakeholders (n = 68). This was piloted in CRTs nationwide (n = 75). A CRT service improvement programme (SIP) was then developed and evaluated in a cluster randomised trial: 15 CRTs received the SIP over 1 year; 10 teams acted as controls. The primary outcome was service user satisfaction. Secondary outcomes included CRT model fidelity, catchment area inpatient admission rates and staff well-being. Workstream 2 was a peer-provided self-management programme that was developed through an iterative process of systematic literature reviewing, stakeholder consultation and preliminary testing. This intervention was evaluated in a randomised controlled trial: 221 participants recruited from CRTs received the intervention and 220 did not. The primary outcome was re-admission to acute care at 1 year of follow-up. Secondary outcomes included time to re-admission and number of days in acute care over 1 year of follow-up and symptoms and personal recovery measured at 4 and 18 months’ follow-up.

Results

Workstream 1 – a 39-item CRT fidelity scale demonstrated acceptability, face validity and promising inter-rater reliability. CRT implementation in England was highly variable. The SIP trial did not produce a positive result for patient satisfaction [median Client Satisfaction Questionnaire score of 28 in both groups at follow-up; coefficient 0.97, 95% confidence interval (CI) –1.02 to 2.97]. The programme achieved modest increases in model fidelity. Intervention teams achieved lower inpatient admission rates and less inpatient bed use. Qualitative evaluation suggested that the programme was generally well received. Workstream 2 – the trial yielded a statistically significant result for the primary outcome, in which rates of re-admission to acute care over 1 year of follow-up were lower in the intervention group than in the control group (odds ratio 0.66, 95% CI 0.43 to 0.99; p = 0.044). Time to re-admission was lower and satisfaction with care was greater in the intervention group at 4 months’ follow-up. There were no other significant differences between groups in the secondary outcomes.

Limitations

Limitations in workstream 1 included uncertainty regarding the representativeness of the sample for the primary outcome and lack of blinding for assessment. In workstream 2, the limitations included the complexity of the intervention, preventing clarity about which were effective elements.

Conclusions

The CRT SIP did not achieve all its aims but showed potential promise as a means to increase CRT model fidelity and reduce inpatient service use. The peer-provided self-management intervention is an effective means to reduce relapse rates for people leaving CRT care.

Competing Risk of Death in Elderly Patients with Newly Diagnosed Stage I Breast Cancer

BACKGROUND

The majority of newly diagnosed breast cancers in the US are in women aged older than 65 years who can have additional comorbidities. Balancing the risks and benefits of treatment should take into account these competing risks of death.

STUDY DESIGN

The Surveillance, Epidemiology, and End Results Program-Medicare database was used to identify women with stage I breast cancer undergoing operations from 2004-2012. Using neural network analysis, comorbidities associated with mortality were grouped into clinically relevant categories. Cumulative incidence graphs and Fine and Gray competing risk regression analyses were used to study the association of age, race, comorbidity groupings, and tumor variables with 3 competing mortality outcomes: dead of disease (DOD), dead of other cancers (DOC), and non-cancer death (NCD).

RESULTS

The overall cumulative incidence of mortality was 4.9% for DOD, 3.7% for DOC, and 21.3% for NCD for the 47,220 patients studied. For all patients, the 5- and 8-year probability of DOD was 3% and 4.7%, for DOC 1.9% and 3.5%, and for NCD 9.8% and 18.9%, respectively. The presence of any major comorbidity (eg cardiovascular or neurologic disorders) significantly increased the probability of NCD, and estrogen receptor status was the strongest predictor of DOD. Given patient age, comorbidity, and estrogen receptor status, an estimate of competing risks of death from DOD, DOC, and NCD can be calculated.

CONCLUSIONS

To aid clinical decision making, we quantify competing risks of death in patients with stage I breast cancer by taking into account patient age, comorbidity, and estrogen receptor status.

Rural and metropolitan South Australian mental health workers' views about nurse prescribing: A thematic analysis

Almost one third of the South Australian population reside in regional locations, which are serviced by just 8% of the State's total psychiatrist workforce. Consequently, access to psychotropic medications in regional South Australia (SA) can be challenging. Granting prescribing rights to mental health nurses (MHNs) located in regional settings presents an opportunity to increase consumer access to psychotropic medications. The aim of the study was to understand the perspectives of mental health workers (MHWs) practising in regional and metropolitan settings towards MHN prescribing. The study adopted a qualitative approach. Seventeen MHWs participated in three focus groups, including two in regional SA and one in a metropolitan site within the State of SA. Participants reported difficulties in accessing medicines in regional areas. The regional focus groups indicated that MHN prescribing may help to release psychiatrists' time and provide quicker assessment and diagnosis. By contrast, the metropolitan focus group expressed reservations about MHN prescribing. Participants indicated that suitable governance structures supported by appropriate education programmes were a necessary prerequisite for MHN prescribing of psychotropic medications. MHN prescribing may help to mitigate the impact of psychiatrist shortages in regional South Australia and possibly in other areas of the world where recruitment is a challenge. The provision of adequate education and the establishment of a suitable governance and support framework are considered necessary steps to progress MHN prescribing.

Epilepsy-Induced Reduction in HCN Channel Expression Contributes to an Increased Excitability in Dorsal, But Not Ventral, Hippocampal CA1 Neurons

CA1 neurons in epileptic animals are vulnerable to selective changes in ion channel expression, called acquired channelopathies, which can increase the excitability of a neuron. Under normal conditions there is a gradient of ion channel expression and intrinsic excitability along the longitudinal, dorsoventral axis of hippocampal area CA1 of the rodent. Many of these channels, including M-channels, GIRK channels and HCN channels, all have dorsoventral expression gradients that might be altered in rodent models of epilepsy. Here, we show that the excitability of dorsal, but not ventral CA1 neurons, had an increased firing rate, reduced interspike interval (ISI) and increased input resistance in a status epilepticus (SE) model of temporal lobe epilepsy (TLE). As a result, the excitability of CA1 neurons became uniform across the dorsoventral axis of the rat hippocampus post-SE. Using current clamp recordings with pharmacology and immunohistochemistry, we demonstrate that the expression of HCN channels was downregulated in the dorsal CA1 region post-SE, while the expression of M and GIRK channels were unchanged. We did not find this acquired channelopathy in ventral CA1 neurons post-SE. Our results suggest that the excitability of dorsal CA1 neurons post-SE increase to resemble the intrinsic properties of ventral CA1 neurons, which likely makes the hippocampal circuit more permissible to seizures, and contributes to the cognitive impairments associated with chronic epilepsy.

Value of Axillary Ultrasound after Negative Axillary MRI for Evaluating Nodal Status in High-Risk Breast Cancer

BACKGROUND

It is assumed that axillary ultrasound (AxUS) is the best method for axillary nodal evaluation in newly diagnosed breast cancer patients. However, few have evaluated the efficacy of preoperative axillary MRI. We compared the statistical accuracy of AxUS and MRI in detecting nodal metastases among breast cancer patients who were selected for neoadjuvant chemotherapy.

STUDY DESIGN

We retrospectively analyzed 219 breast cancer patients undergoing neoadjuvant chemotherapy from 2007 to 2015, all of whom had AxUS and breast MRI before chemotherapy. Two breast radiologists, blinded to clinical, pathologic, and AxUS findings, re-reviewed all breast MRIs, specifically focusing on axillary nodal characteristics. We correlated clinico-pathologic characteristics, AxUS, and MRI findings, and quantified predictive values of both imaging modalities.

RESULTS

Overall, 101 of 219 (47%) patients had T2 tumors. The most common abnormal nodal finding was size >10 mm. Axillary ultrasound and MRI agreed on nodal status in 192 of 219 patients (87.6%). When correlated with pre-chemotherapy needle biopsy in 129 patients, AxUS and axillary MRI performed similarly (sensitivity of 99.1% vs 97.4% and specificity 15.4% vs 15.4%, respectively). Only 4 of 129 (3.1%) patients had a negative MRI and positive AxUS; 3 of 4 of these patients (75%) had a positive biopsy and 2 of 3 had positive lymph nodes on final pathology, therefore suggesting MRI missed clinically significant disease in only 2 of 129 (1.5%) patients.

CONCLUSIONS

In a high-risk patient population, AxUS and MRI have similar statistical profiles in evaluating axillary nodal status. Routine use of AxUS after a normal axillary MRI is not warranted.

Abstract P1-11-13: Depomedroxyprogesterone therapy for hot flashes in survivors of ER-expressing breast cancer: Impact on recurrence and survival

Background

Survivors of ER-expressing operable breast cancer (ER+BC) generally do not receive hormone replacement therapy for menopausal symptoms due to concern about provoking recurrence of disease. Single dose depomedroxyprogesterone acetate (MPA) 400 mg IM has previously been shown (Loprinzi CL, et al. J Clin Oncol 2006;24:1409) to be the most effective non-estrogen therapy available for menopausal hot flashes (HF) but long-term evidence of safety in survivors of ER+BC is lacking.

Methods

Consecutive patients previously diagnosed with ER+BC who received MPA for HF between January 2007 and December 2012 were retrospectively identified in the breast cancer patient database at Mayo Clinic Arizona. Medical records were audited for breast cancer outcomes in these cases and in contemporaneous control patients with ER+BC who did not receive MPA, matched for age, stage of disease, and year of diagnosis. Statistical comparisons of local-regional recurrence and event-free survival were performed.

Results

92 patients who received MPA were identified and matched 1:1 with contemporaneous controls. Median follow-up duration was 5.7 years in cases and 4.5 years in controls. Estimated local-regional recurrence free survival at 10 years was 85% (95% CI, 72-100%) in cases and 95% (95% CI, 86-100%) in controls. Matched pairs hazard ratio was 1.0 (95% CI, 0.06-16.0) for local-regional recurrence free survival. Estimated event-free survival at 10 years was 81% (95% CI, 69-97%) in cases and 76% (95% CI, 64-92%) in controls. Matched pairs hazard ratio was 0.38 (95% CI, 0.10-1.41) for event-free survival. The majority (77%) of case patients experienced satisfactory relief of hot flashes from MPA injection.

Conclusion

In this retrospective case-control study we were unable to identify a detrimental effect of MPA therapy for HF in survivors of ER+BC. MPA may be acceptable for management of HF in this population.

Machine learning to support social media empowered patients in cancer care and cancer treatment decisions

Background

A primary variant of social media, online support groups (OSG) extend beyond the standard definition to incorporate a dimension of advice, support and guidance for patients. OSG are complementary, yet significant adjunct to patient journeys. Machine learning and natural language processing techniques can be applied to these large volumes of unstructured text discussions accumulated in OSG for intelligent extraction of patient-reported demographics, behaviours, decisions, treatment, side effects and expressions of emotions. New insights from the fusion and synthesis of such diverse patient-reported information, as expressed throughout the patient journey from diagnosis to treatment and recovery, can contribute towards informed decision-making on personalized healthcare delivery and the development of healthcare policy guidelines.

Methods and findings

We have designed and developed an artificial intelligence based analytics framework using machine learning and natural language processing techniques for intelligent analysis and automated aggregation of patient information and interaction trajectories in online support groups. Alongside the social interactions aspect, patient behaviours, decisions, demographics, clinical factors, emotions, as subsequently expressed over time, are extracted and analysed. More specifically, we utilised this platform to investigate the impact of online social influences on the intimate decision scenario of selecting a treatment type, recovery after treatment, side effects and emotions expressed over time, using prostate cancer as a model. Results manifest the three major decision-making behaviours among patients, Paternalistic group, Autonomous group and Shared group. Furthermore, each group demonstrated diverse behaviours in post-decision discussions on clinical outcomes, advice and expressions of emotion during the twelve months following treatment. Over time, the transition of patients from information and emotional support seeking behaviours to providers of information and emotional support to other patients was also observed.

Conclusions

Findings from this study are a rigorous indication of the expectations of social media empowered patients, their potential for individualised decision-making, clinical and emotional needs. The increasing popularity of OSG further confirms that it is timely for clinicians to consider patient voices as expressed in OSG. We have successfully demonstrated that the proposed platform can be utilised to investigate, analyse and derive actionable insights from patient-reported information on prostate cancer, in support of patient focused healthcare delivery. The platform can be extended and applied just as effectively to any other medical condition.

The estimated number of potential PrEP users among gay-identifying men who have sex with men in Australia

We estimated the size of the population of gay-identified men who have sex with men (gay men) eligible for PrEP in Australia under the current national PrEP guidelines. Using input indicators from the Australian Bureau of Statistics, the national representative survey Second Australian Study of Health and Relationships, and national HIV- behavioural surveillance, we calculated the size of the population of sexually active gay men and estimated a range for the number eligible for PrEP using different scenarios based on the guidelines. In 2015, an estimated 108,850 sexually-active 16-69-year-old gay men were classified as at risk of acquiring HIV in Australia. Of these men, 10,558 to 30,913 (9.7%-28.4%) were classified as being at high risk and therefore eligible for PrEP, most commonly due to recent receptive condomless intercourse with casual partners (6.1% to 15.5%), STI infections (5.4% to 10.6%) or the use of crystal methamphetamine (1.4% to 9.4%). The higher estimates included men who may have been at HIV risk for shorter time periods or with fewer partners. Australian PrEP guidelines recommend targeting PrEP to people at high HIV risk. Our estimation of potential PrEP users informed PrEP implementation in Australia. The choice of PrEP eligibility criteria, and interpretation of the guidelines, strongly affects the population estimates. In the future, higher numbers of gay men may become eligible for PrEP, because the estimates are largely defined by and follow trends in condomless anal intercourse. Our estimation methods can be adapted to other settings.

Reliability and Validity of the Critical-Care Pain Observation Tool: A Rapid Synthesis of Evidence

Staff in a tertiary hospital critical care unit in Doha, Qatar, suggested that the Critical-Care Pain Observation Tool (CPOT) would be a better tool for assessing pain in ventilated and sedated patients than current local practice. We undertook a rapid synthesis of evidence to establish whether current research supports use of CPOT for assessing pain in ventilated and sedated patients in a critical care setting. CPOT has been shown in reviews and more recent primary studies to be reliable and valid for most patients unable to self-report in critical care settings. This finding is supported by several guidelines. Studies also suggest that CPOT is feasible for use in research and clinical practice though training of observers is important. Further research may be warranted to strengthen current evidence, particularly in patients with neurological trauma.

Antipsychotic treatment of very late-onset schizophrenia-like psychosis (ATLAS): a randomised, controlled, double-blind trial

BACKGROUND

Very late (aged ≥60 years) onset schizophrenia-like psychosis occurs frequently but no placebo-controlled, randomised trials have assessed the efficacy and risks of antipsychotic treatment. We investigated whether low-dose amisulpride (100 mg daily) is superior to placebo in reducing psychosis symptoms over 12 weeks and whether any benefit is maintained by continuing treatment after 12 weeks.

METHODS

The ATLAS double-blind controlled trial enrolled participants from 25 old age psychiatry services in the UK. Eligible participants (ie, those with a diagnosis of very late-onset schizophrenia-like psychosis and a Brief Psychiatric Rating Scale [BPRS] score of ≥30, without cognitive impairment) were randomly assigned (1:1:1) to one of three groups in a two-stage trial: amisulpride in stage 1 and 2 (group A), amisulpride then placebo (group B), or placebo then amisulpride (group C). Treatment (100 mg oral amisulpride daily vs placebo) was given for 12 weeks in stage 1 and, initially, 24 weeks then reduced to 12 weeks in stage 2. Participants, investigators, and outcome assessors were masked to treatment allocation. Primary outcomes were psychosis symptoms assessed by the BPRS at 4, 12, and 24, or 36 weeks, and trial treatment discontinuation for non-efficacy. The primary, secondary, and safety endpoints were all analysed in participants given at least one dose of study treatment in modified intention-to-treat analyses. This study is registered with EudraCT, number 2010-022184-35, and ISRCTN, number ISRCTN45593573.

FINDINGS

Between Sept 27, 2012, and June 28, 2016, we recruited 101 participants. 92 (91%) of 101 participants took trial medication, of whom 59 (64%) completed stage 1 and 34 (58%) of these 59 participants completed stage 2 treatment. Despite suboptimal compliance, improvements in BPRS scores at 12 weeks were 7·7 points (95% CI 3·8-11·5, p=0·0002) greater with amisulpride (mean 11·9 points [SE 1·3]) than with placebo (4·2 points [1·0]). In stage 2, BPRS scores improved by a mean of 1·1 points (1·6) from 12 weeks to the final assessment in those who continued amisulpride but deteriorated by 5·2 points (2·0) in those who switched from amisulpride to placebo (difference 6·3 points [95% CI 0·9-11·7], p=0·024). Fewer participants who were allocated amisulpride than placebo stopped treatment because of non-efficacy in stage 1 (p=0·010) and stage 2 (p=0·031). Serious adverse events were reported more frequently in the amisulpride group than in the placebo group in stage 1 (p=0·057) and stage 2 (p=0·19). The most common serious adverse events were infection (five patients in the amisulpride group, three in the placebo group) and extrapyramidal side-effects (three patients in the amisulpride group, none in the placebo group). Five patients died during the study, one from a gastric ulcer bleed before treatment started (group B), two while taking stage 2 treatment (one in group A and one in group C), and two who stopped trial treatment in stage 1 and died many weeks later (one in group B and one in group C). No deaths were related to treatment.

INTERPRETATION

Low-dose amisulpride is effective and well tolerated as a treatment for very late-onset schizophrenia-like psychosis, with benefits maintained by prolonging treatment.

What do mental health workers in the bush think about mental health nurse prescribing? A cross-sectional study

INTRODUCTION

Relatively few psychiatrists live and work in rural South Australia. The rural GP is an essential component of support for people with mental health problems. However, considerable GP maldistribution between rural and metropolitan Australia still exists. Thus, accessing health services, including medication, becomes challenging for rural communities. Extending mental health nurse prescribing could be a strategy to build additional capacity to complement the GPs and psychiatrists who practice in rural South Australia. Until now, no studies have examined mental health workers' attitudes towards nurse prescribing in rural Australia.

OBJECTIVE

To examine the attitudes of rural and remote South Australian mental health workers about mental health nurse prescribing.

DESIGN/METHOD

A cross-sectional survey assessing mental health workers' attitudes to mental health nurse prescribing.

SETTING

The study was conducted across South Australia, excluding metropolitan Adelaide.

PARTICIPANTS

Mental health workers employed by the Country Health South Australia Local Health Network for Mental Health.

RESULTS

Of the 289 potential participants, 93 (32%) responded and were included in this study. All the respondents reported positive attitudes towards mental health nurse prescribing. However, they expressed concerns about safety, educational preparation and supervision structures.

CONCLUSION

The attitudes of rural South Australian mental health workers are not a barrier to mental health nurse prescribing. The implementation and sustainability of mental health nurse prescribing will require additional staff training in psychopharmacology and a governance framework to assure quality and safety. Policy-makers need to focus their attention on the uptake of mental health nurse prescribing in parts of Australia that struggle to attract and retain psychiatrists.

Refined estimates of local recurrence risks by DCIS score adjusting for clinicopathological features: a combined analysis of ECOG-ACRIN E5194 and Ontario DCIS cohort studies

PURPOSE

Better tools are needed to estimate local recurrence (LR) risk after breast-conserving surgery (BCS) for DCIS. The DCIS score (DS) was validated as a predictor of LR in E5194 and Ontario DCIS cohort (ODC) after BCS. We combined data from E5194 and ODC adjusting for clinicopathological factors to provide refined estimates of the 10-year risk of LR after treatment by BCS alone.

METHODS

Data from E5194 and ODC were combined. Patients with positive margins or multifocality were excluded. Identical Cox regression models were fit for each study. Patient-specific meta-analysis was used to calculate precision-weighted estimates of 10-year LR risk by DS, age, tumor size and year of diagnosis.

RESULTS

The combined cohort includes 773 patients. The DS and age at diagnosis, tumor size and year of diagnosis provided independent prognostic information on the 10-year LR risk (p ≤ 0.009). Hazard ratios from E5194 and ODC cohorts were similar for the DS (2.48, 1.95 per 50 units), tumor size ≤ 1 versus  > 1-2.5 cm (1.45, 1.47), age ≥ 50 versus < 50 year (0.61, 0.84) and year ≥ 2000 (0.67, 0.49). Utilization of DS combined with tumor size and age at diagnosis predicted more women with very low (≤ 8%) or higher (> 15%) 10-year LR risk after BCS alone compared to utilization of DS alone or clinicopathological factors alone.

CONCLUSIONS

The combined analysis provides refined estimates of 10-year LR risk after BCS for DCIS. Adding information on tumor size and age at diagnosis to the DS adjusting for year of diagnosis provides improved LR risk estimates to guide treatment decision making.

Patient-directed self-management of pain (PaDSMaP) compared to treatment as usual following total knee replacement; a randomised controlled trial

Background

Self-administration of medicines by patients whilst in hospital is being increasingly promoted despite little evidence to show the risks and benefits. Pain control after total knee replacement (TKR) is known to be poor.

The aim of the study was to determine if patients operated on with a TKR who self-medicate their oral analgesics in the immediate post-operative period have better pain control than those who receive their pain control by nurse-led drug rounds (Treatment as Usual (TAU)).

Methods

A prospective, parallel design, open-label, randomised controlled trial comparing pain control in patient-directed self-management of pain (PaDSMaP) with nurse control of oral analgesia (TAU) after a TKR. Between July 2011 and March 2013, 144 self-medicating adults were recruited at a secondary care teaching hospital in the UK. TAU patients (n = 71) were given medications by a nurse after their TKR. PaDSMaP patients (n = 73) took oral medications for analgesia and co-morbidities after two 20 min training sessions reinforced with four booklets. Primary outcome was pain (100 mm visual analogue scale (VAS)) at 3 days following TKR surgery or at discharge (whichever came soonest). Seven patients did not undergo surgery for reasons unrelated to the study and were excluded from the intention-to-treat (ITT) analysis.

Results

ITT analysis did not detect any significant differences between the two groups’ pain scores. A per protocol (but underpowered) analysis of the 60% of patients able to self-medicate found reduced pain compared to the TAU group at day 3/discharge, (VAS -9.9 mm, 95% CI -18.7, − 1.1). One patient in the self-medicating group over-medicated but suffered no harm.

Conclusion

Self-medicating patients did not have better (lower) pain scores compared to the nurse-managed patients following TKR. This cohort of patients were elderly with multiple co-morbidities and may not be the ideal target group for self-medication.

Feasibility study suggests no impact from protected engagement time on adverse events in mental health wards for older adults

Hospital adverse events, such as falls, violence and aggression, security, self-harm, and suicide, are difficult to manage in older people with dementia. The purpose of the present study was to determine whether protected engagement time (PET) resulted in lower adverse events and incidents compared to comparable non-PET wards for people admitted to inpatient older people's mental health wards. Ten inpatient wards for older people were included. Five followed a PET-management pathway, while five continued usual care. All adverse events and incidents were recorded in routine hospital records over 72 weeks. Data were gathered from these records and analysed as rate per person per week to assess differences in frequency and type of adverse events between wards. A total of 4130 adverse events were recorded. In the PET wards, a mean of 0.38 adverse events occurred per person per week compared to 0.40 in non-PET wards. No statistically-significant differences were found between PET and non-PET wards for adverse events (P = 0.93), or for adverse events of any particular type (P ≥ 0.15). Therefore, there is no evidence to suggest that PET has any impact on adverse events in older people's mental health wards. Further investigation with a larger cohort is warranted, using a definitive, phase 3, clinical trial.

Protected engagement time on older adult mental health wards: A thematic analysis of the views of patients, carers, and staff

During protected engagement time (PET), ward routines are adjusted so that staff can spend time together with patients without interruption. The aim of PET is to increase staff and patient interaction on wards, and ultimately patient well-being. Although PET has been implemented on inpatient wards within the UK, including older adult wards, there is no systematic evidence as to how PET is carried out or how it is experienced by staff, patients, and families. Semistructured interviews were conducted with 28 participants (8 patients, 10 family members, and 10 ward staff) from three different wards with PET, and transcriptions were analysed using thematic analysis. Three themes were identified: (i) the patient is at the heart of care; (ii) PET depends on staff; and (iii) tensions in how PET operates. There was support in our sample for the principles of PET and its potential for a positive impact on patient well-being. However, the implementation of PET was identified as challenging, highlighting an existing tension between an individual's needs and the wider needs of patients on the ward as a whole. The impact of PET was generally described as being dependent on how PET was organized and the level of staff commitment to PET. Participants emphasized that if PET is to be successful, then it should be a fluid process that fits in with the local context.

Perception of nurse prescribing among nurses and psychiatrists in a developing country: A cross-sectional survey

Nurse prescribing has the potential to improve patients' access to, and experiences of, treatment. The aim of the present study was to examine nurse and psychiatrist attitudes about this extended role in a developing country. We conducted a cross-sectional survey using a previously-used, 65-item, seven subscale measure of attitudes to nurse prescribing in mental health. We achieved a 79% response rate. The majority of participants had trained in developing countries where nurse prescribing has yet to be implemented. Across five subscales (general beliefs, impact, uses, training, and supervision), both groups reported positive attitudes about nurse prescribing. Both groups scored the training subscale particularly highly. Compared with psychiatrists, nurses were more confident about the range of clinical settings where nurse prescribing could be applied (e.g. acute inpatient and substance use). Although both groups had less favourable attitudes on the two subscales relating to clinical and legal responsibility, compared to nurses, psychiatrists were more undesirable. Although, overall, clinician attitudes do not seem to represent a barrier towards the potential implementation of nurse prescribing in the study setting, clarity about clinical and legal responsibility needs to be addressed.

Chinese Health Improvement Profile for people with severe mental illness: A cluster-randomized, controlled trial

The aim of the present study was to establish the feasibility of conducting a full-scale trial and to estimate the preliminary effect of a Chinese Health Improvement Profile (CHIP) intervention on self-reported physical well-being of people with severe mental illness (SMI). The study used a parallel-group, open-label, cluster-randomized, controlled trial (RCT) design. Twelve community psychiatric nurses (CPN) and their corresponding 137 patients with SMI were randomized into the CHIP or treatment-as-usual (TAU) groups. After training, the CPN completed the CHIP at baseline and 12 months, and the findings were used to devise an individualized care plan to promote health behaviour change. Patients were assessed at baseline and 6 and 12 months after starting the intervention. There was an observed positive trend of improvement on the physical component subscale of SF12v2 in the CHIP group compared to the TAU group after 12 months, but the difference did not reach statistical significance (P = 0.138). The mental component subscale showed a similar positive trend (P = 0.077). CHIP participants were more satisfied with their physical health care than TAU patients (P = 0.009), and the CPN were positive about the usefulness/acceptability of the intervention. There were significant within-group improvements in the total numbers of physical health risks, as indicated by the CHIP items (P = 0.005). The findings suggest that it is feasible to conduct a full-scale RCT of the CHIP in future. The CHIP is an intervention that can be used within routine CPN practice, and could result in small-modest improvements in the physical well-being of people with SMI.

The educational preparation of nurses in a developing economy and patient mortality

BACKGROUND

Most studies have reported that higher levels (baccalaureate degree) of educational attainment by nurses are associated with lower levels of patient mortality. Researchers working in developed economies (e.g. North America and Europe) have almost exclusively conducted these studies. The value of baccalaureate nurse education has not been tested in countries with a developing economy.

METHOD

A retrospective observational study conducted in seven hospitals. Patient mortality was the main outcome of interest. Anonymized data were extracted from nurses and patients from two different administrative sources and linked using the staff identification number that exists in both systems. We used bivariate logistic regression models to test the association between mortality and the educational attainment of the admitting nurse (responsible for assessment and care planning).

RESULTS

Data were extracted for 11 918 (12, 830 admissions) patients and 7415 nurses over the first 6 months of 2015. The majority of nurses were educated in South Asia and just over half were educated to at least bachelor degree level. After adjusting for confounding and clustering, nurse education was not found to be associated with mortality.

IMPLICATIONS FOR NURSING AND HEALTH POLICY

Our observations may suggest that in a developing economy, the academic level of nurses' education is not associated with a reduction in patient mortality. Findings should be interpreted with considerable caution but do challenge widely held assumptions about the value of baccalaureate-prepared nurses. Further research focused on nursing education in developing economies is required to inform health policy and planning.

Novel psychoactive substance use by mental health service consumers: an online survey of inpatient health professionals’ views and experiences

Purpose

There is evidence that novel psychoactive substances (NPS) are commonly used by people with severe mental illness. The purpose of this paper is to undertake a scoping survey to explore the inpatient mental health workers’ perceptions of NPS use by consumers.

Design/methodology/approach

A cross-sectional online survey of mental health professionals is used in the study. The participants were opportunistically recruited through social media and professional networks.

Findings

A total of 98 participants (of 175 who started the survey) were included in the analysis. All reported that some patients had used NPS prior to admission. Over 90 per cent of participants reported observing at least one adverse event relating to NPS use in the previous month. The majority of participants reported that patients had used NPS during their inpatient admission. Three quarters were not clear if their workplace had a policy about NPS. Most wanted access to specific NPS information and training. The participants reported that they lacked the necessary knowledge and skills to manage NPS use in the patients they worked with.

Research limitations/implications

Whilst the authors are cautious about the generalisability (due to methodological limitations), the findings provide useful insight into the perceptions of inpatient staff regarding the extent and impact of NPS use including concerns regarding the impact on mental and physical health, as well as ease of availability and a need for specific training and guidance.

Practical implications

Mental health professionals require access to reliable and up-to-date information on changing trends in substance use. Local policies need to include guidance on the safe clinical management of substance use and ensure that NPS information is included.

Originality/value

To the best of the authors’ knowledge, this is the first survey of the perceptions of mental health staff working in inpatient mental health settings regarding NPS. The findings suggest that NPS is a common phenomenon in inpatient mental health settings, and there is a need for more research on the impact of NPS on people with mental health problems.
