Improving care for patients in the outlying wards: Lessons from patients' care experience

IMPORTANCE

Overcrowding in hospitals and lack of capacity in general medical wards can result in a medical patient being transferred to other specialty wards often referred as 'outlying' or 'boarding' wards.

OBJECTIVES

We explored the experiences of our outlying patients to identify local factors that affect their care experience and inform interventions that could improve their care deliveries and outcomes.

DESIGN, SETTING, AND PARTICIPANTS

Qualitative interviews using semi-structured questions were conducted in 21 medical patients from a mixture of specialty wards in a large tertiary NHS hospital.

MAIN OUTCOMES AND MEASURES

Perceptions of the factors contributing to the experience of being a patient on a boarding ward, and potential solutions.

RESULTS

Almost all participants reported experiences of good care in an outlying ward. Positive comments highlighted good nursing care, restful environment and a strong focus on patient-centred care. However, none of the participants could identify the team or consultant responsible for their care and this was linked to multiple doctors being involved in the patient's care. Participants also perceived that the frequency of review was reduced and occurred much later in the day than that experienced in the medical ward. Most felt indifferent about the care ownership, timing and frequency of review but in some cases, this led to confusion and the perception of poor progress. Further, participants felt that they had to actively seek information relating to clinical progress. Negative experience of discharge planning was also reported. The associated themes included conflicting information and delays in social care provision. This led to anxiety, frustration and the perception of being a barrier to patient flow.

CONCLUSIONS AND RELEVANCE

Patient experience of the outlying ward is positive, and this can provide a foundation for improvement. Our findings suggest that better care processes and improved communication are needed to promote equity and quality of care. However, this should be complemented with efforts to overcome wider challenges that affect the entire continuum of flow within the healthcare system.

Strategies to Improve Recruitment to a De-escalation Trial: A Mixed-Methods Study of the OPTIMA Prelim Trial in Early Breast Cancer

AIMS

De-escalation trials are challenging and sometimes may fail due to poor recruitment. The OPTIMA Prelim randomised controlled trial (ISRCTN42400492) randomised patients with early stage breast cancer to chemotherapy versus 'test-directed' chemotherapy, with a possible outcome of no chemotherapy, which could confer less treatment relative to routine practice. Despite encountering challenges, OPTIMA Prelim reached its recruitment target ahead of schedule. This study reports the root causes of recruitment challenges and the strategies used to successfully overcome them.

MATERIALS AND METHODS

A mixed-methods recruitment intervention (QuinteT Recruitment Intervention) was used to investigate the recruitment difficulties and feedback findings to inform interventions and optimise ongoing recruitment. Quantitative site-level recruitment data, audio-recorded recruitment appointments (n = 46), qualitative interviews (n = 22) with trialists/recruiting staff (oncologists/nurses) and patient-facing documentation were analysed using descriptive, thematic and conversation analyses. Findings were triangulated to inform a 'plan of action' to optimise recruitment.

RESULTS

Despite best intentions, oncologists' routine practices complicated recruitment. Discomfort about deviating from the usual practice of recommending chemotherapy according to tumour clinicopathological features meant that not all eligible patients were approached. Audio-recorded recruitment appointments revealed how routine practices undermined recruitment. A tendency to justify chemotherapy provision before presenting the randomised controlled trial and subtly indicating that chemotherapy would be more/less beneficial undermined equipoise and made it difficult for patients to engage with OPTIMA Prelim. To tackle these challenges, individual and group recruiter feedback focussed on communication issues and vignettes of eligible patients were discussed to address discomforts around approaching patients. 'Tips' documents concerning structuring discussions and conveying equipoise were disseminated across sites, together with revisions to the Patient Information Sheet.

CONCLUSIONS

This is the first study illuminating the tension between oncologists' routine practices and recruitment to de-escalation trials. Although time and resources are required, these challenges can be addressed through specific feedback and training as the trial is underway.

Abstract OT1-06-03: The plasmaMATCH trial: A multiple parallel cohort, open-label, multi-centre phase II clinical trial of ctDNA screening to direct targeted therapies in patients with advanced breast cancer (CRUK/15/010)

Introduction

Circulating tumour DNA (ctDNA) is found in the plasma of over 90% of patients with advanced breast cancer (BC). Screening for the presence of mutations in ctDNA provides a current assessment of the genetic profile of the patient's recurrent BC. The plasmaMATCH trial is designed to assess the potential of ctDNA screening to direct targeted therapies in patients with advanced breast cancer.

Methods

plasmaMATCH is a multi-centre phase IIa umbrella trial platform of ctDNA screening and a therapeutic trial. The study will screen 1000 women with advanced breast cancer, who have received prior systemic treatment in the advanced setting, with digital PCR ctDNA assays for hotspot mutations in ESR1, HER2, AKT1, and PIK3CA, with HER2 copy number assessment, in a central laboratory. The study will recruit from up to 50 sites in the UK. Patients with mutations identified will enter the matching treatment cohort, ESR1 – extended dose fulvestrant 500mg every two weeks, HER2 – neratinib +/- fulvestrant, AKT1 – AZD5363 +/- fulvestrant.

Mutation prevalence is presented with corresponding exact 95% confidence intervals (CIs) both overall and excluding 14 patients who were known to have mutations from a prior screening program. Patients with more than one mutation are included once in each relevant row.

Results

We report the results of prospective ctDNA mutation testing in the first 92 patients. plasmaMATCH opened to recruitment on 15/12/2016. As of 08/06/2017, 120 patients have been registered for ctDNA screening from 7 UK centres, of which 92 have ctDNA screening results available:

14 patients had more than one mutation detected (10 ESR1+PIK3CA, 3 ESR1+AKT1, 1 ESR1+ +HER2+AKT1). ctDNA results were reported in a median of 8 working days.

Of the 40 patients with one or more actionable mutation, 15 have entered a cohort, 16 are being screened for entry into a cohort, 5 are currently receiving further systemic treatment prior to cohort entry and 4 will not enter a cohort. One additional patient has entered a treatment cohort on the basis of a mutation detected in an alternative tumour sequencing initiative.

Conclusions

plasmaMATCH ctDNA demonstrates the feasibility and accuracy of ctDNA testing as a screening tool for patients with advanced BC, with a high rate of subsequent recruitment into matching therapeutic trials.

Abstract P4-21-08: A phase I/II of S-222611, a reversible EGFR and HER2 inhibitor, combined with trastuzumab +/- chemotherapy in patients with HER2-positive metastatic breast cancer

Background: S-222611, an oral, reversible EGFR and HER2 inhibitor, has been shown to be well-tolerated as monotherapy at a dose of 800mg daily with good anti-tumor activity in patients previously treated with other anti-HER2-based regimens. This study evaluated the tolerability and safety of daily oral administration of S-222611 (S) in combination with trastuzumab (T), trastuzumab + vinorelbine (T+V) and trastzumab + capecitabine (T+C) in HER2-positive (HER2+) metastatic breast cancer (MBC) with or without brain metastases.

Methods: This study was performed as a 3+3 dose escalation followed by expansion to examine the tolerability and safety of S in combination with T, T+V and T+C in Arms A, B and C, respectively. S was administered orally once daily, starting at a dose of 400mg in Arm A, and 200mg in Arms B and C. The dosing of T was 8mg/kg loading followed by 6mg/kg or fixed dose of 600mg subcutaneously every 21 days as recommended. V was administered at 60mg/m2 orally on Day 1 and 8 of a 21-day cycle, and C 1000mg/m2 orally daily for 14 days followed by a 7-day rest period. All patients had HER2+ MBC and were required to have progressed following at least one prior line of anti-HER2 therapy. Prior treatments with V and C were permitted. Anti-diarrhea prophylaxis with loperamide was not required.

Results: A total of 45 patients were enrolled. All patients had received prior anti-tumor regimens including T (n=45), T-DM1 (n=26), pertuzumab (n=9) and lapatinib (n=12). The clinically recommended doses of S at which most adverse events were manageable,were determined as:600mg in Arm A, 200mg in Arm B and 400mg in Arm C. Dose limiting toxicities included Grade 3 diarrhea for Arm A; and Grade 4 neutropenia, Grade 3 Hypokalemia and Hypophosphatemia for Arm B. As of 13 May 2016, treatment is ongoing in 2 patients. No other Grade 4 AEs related to S-222611 have been observed. Grade 3 bilirubin elevation was observed in 5/45 patients, probably due to transporter (UGT1A1) inhibition, while no G3/4 liver dysfunction was reported. RECIST partial responses (PR) were observed in 6 of 9 patients in Arm A and 5 of 9 patients in Arm C, at respective clinically recommended doses. Nine of 45 patients had brain metastases; 4 of these patients showed RECIST PR including an intracranial tumor response in one patient (400mg in Arm C) who had prior treatments with paclitaxel, T+C, T-DM1 and V after diagnosis of BM.

Conclusions: The clinically recommended doses of S-222611 combined with T, T +V and T+C were determined for further clinical studies. Clinical benefit (PR and SD >6 month) was seen with each combination even in heavily pre-treated HER2+ MBC patients.

Abstract OT3-02-12: OPTIMA (optimal personalised treatment of early breast cancer usIng multi-parameter analysis), a prospective trial to validate the predictive utility and cost-effectiveness of gene expression test-directed chemotherapy decisions

Background: Multi-parameter gene expression assays (MPAs) are widely used to estimate individual patient residual risk and to guide chemotherapy use in hormone-sensitive HER2-negative node-negative early breast cancer. These uses of MPAs have not yet been prospectively validated. OPTIMA aims to validate the use of MPA testing to predict chemotherapy sensitivity in a largely node-positive breast cancer population.

Methods: OPTIMA is a partially blinded multi-center, phase 3 randomized controlled trial with an adaptive two-stage design. The preliminary phase (OPTIMA prelim) evaluated the performance of MPAs to identify a suitable test(s) to be used in the main efficacy trial and assessed the feasibility and acceptability of a large UK trial. Eligible patients are men or women aged 40 years or older who have surgically resected early stage breast cancer, which is ER-positive and HER2-negative and who have either 1-9 involved axillary lymph nodes or tumors of at least 30mm diameter. Randomization is to standard management (chemotherapy followed by endocrine therapy) or to MPA-directed treatment. Those with a tumor categorized as "high-risk" by the test will be assigned to standard management whilst those at "low-risk" will be treated with endocrine therapy alone. OPTIMA prelim used Oncotype DX as the primary discriminator; the main trial will use Prosigna (PAM50). The co-primary outcomes are (1) Invasive Disease Free Survival (IDFS) and (2) cost-effectiveness of test-directed therapy compared to standard practice. Secondary outcomes include IDFS in "low-risk" patients, distant disease free survival, breast cancer specific survival, overall survival and quality of life. An integrated qualitative recruitment study will identify and address challenges to recruitment and informed consent. Tumor blocks from all consenting participants will be banked allowing the performance of alternative MPA technologies to be evaluated. Recruitment of 4500 patients over 4 years will permit demonstration of 3% non-inferiority of test-directed treatment, with 5% significance and 85% power, assuming 3 years follow-up and a control arm 5-year IDFS of at least 85%. The addition of patients from OPTIMA prelim will allow non-inferiority to be assessed with 2.5% significance.

Results: OPTIMA-prelim recruited 412 patients in 23 months from 35 sites. It confirmed the acceptability of randomization to patients with a 47% acceptance rate, and to clinicians and hence the feasibility of a large prospective trial of test-directed treatment running in 100-plus UK sites. It showed that investment into research on test-directed therapy, especially with Prosigna, should be of substantial value to the NHS.

Conclusion: OPTIMA, as one of two large scale prospective trials validating the use of test-guided chemotherapy in node-positive hormone-sensitive early breast cancer will have a global impact on patient treatment. Recruitment into the main efficacy trial will commence in October 2015.

A dose escalation (DE), pharmacokinetic (PK), and pharmacodynamic (PD) study of OSI-930 and erlotinib (E) in patients (pts) with advanced solid tumors

3550

Background: EGFR and VEGFR are important targets in a number of human cancers with common downstream signalling pathways. Combined blockade of EGFR-VEGFR with E and OSI-930 has shown additional antitumor activity compared to either agent alone with long-term remissions in multiple xenograft models. Methods: Sequential cohorts of pts with advanced refractory solid tumors were treated with OSI-930 BID with addition of E QD from Day 8 and beyond to determine the maximum tolerated dose (MTD) and to evaluate safety, PK and efficacy of the combination. Escalation followed a standard 3+3 design until dose-limiting toxicity (DLT) was observed in ≥ 2/6 pts. PK of OSI-930, E and its metabolite OSI-420 were determined. Levels of soluble VEGFR2 (sVEGFR2) in plasma were also measured. Results: 16 pts have been entered (13M/3F); median age 63 years (range 41–78), PS ≤2 and 38% pts with mCRC. OSI-930/E were administered at 3 levels [mg(pts entered/evaluable)]; 200 BID/100 QD (7/6), 200 BID/150 QD (4/3), and 300 BID/150 QD (5/5). Median duration of therapy was 8 weeks (range 1–22). DLT was seen in 1/6 pts at 200 BID/100 QD (>5 day interruption due to G4 neutropenia); and 1/5 at 300 BID/150 QD (G3 Asthenia/lethargy). Other common related toxicities (% all grades:% g3/4) were: skin-related (rash, HFS etc) (85:23), Asthenia/lethargy/fatigue (69:15), diarrhea (77:8), anorexia (92:0), and transaminitis (31:15). Reduction and/or interruptions of one or both study drugs during or beyond the initial 28 days were required in 8/14 pts. Six of 11 pts evaluable for response achieved SD ≥12 weeks. Median plasma Cmax (and AUCTau) of OSI -930 for Cohort 3 (300 BID/150 QD) were: 0.826 (6.08), 0.947 (5.57), and 1.66 (14.3) μg/mL (μg.hr/mL) on Days 7, 8 and 22, respectively. Exposure of OSI-930 increased approximately 2-fold upon co-administration with E at steady-state. OSI-930 appeared not to alter the PK properties of E or the ratio of OSI-420 to E. Decreases in plasma sVEGFR2 were observed, indicating a PD effect of OSI-930. Conclusions: Additional patients are being added to confirm the MTD of the combination. PK data indicate a drug-drug interaction with doubling of the OSI-930 exposure on co-administration with E.

Avian paramyxoviruses of PMV-3 serotype in British turkeys

Serological testing of turkey flocks in Great Britain was undertaken as a result of the isolation of an avian paramyxovirus of serotype PMV-3 from turkeys in 1981 (Macpherson et al., 1983). Turkeys on two of four farms with egg production problems examined for PMV-3 haemagglutination inhibition (HI) antibodies in 1981 were positive. Turkeys on 34 farms were tested for PMV-3 antibodies in 1982. Seven of 16 flocks showing egg production problems and/or respiratory disease were considered positive for PMV-3 (mean log(2) HI titre >/= 2.5), but five of 18 flocks with no reported disease were also positive for PMV-3 antibodies. On one turkey farm the appearance of PMV-3 antibodies and an isolation of a PMV-3 virus coincided with egg production problems. Analysis of HI titres in turkeys vaccinated against Newcastle disease virus (NDV) and unvaccinated birds suggested that significant NDV HI titres are unlikely to be recorded as a result of PMV-3 virus infections of unvaccinated birds. However, while NDV vaccination prior to PMV-3 infection apparently caused slight suppression of the PMV-3 immune response, the HI titres to NDV were boosted considerably in direct relationship to the PMV-3 titre.

Evaluation of mupirocin E-test for determination of isolate susceptibility: comparison with standard agar dilution techniques

Mupirocin E-test strips have been evaluated for their ease of use and accuracy in determining the susceptibilities of 171 strains of Staphylococcus spp., Streptococcus spp., Haemophilus influenzae, and Moraxella catarrhalis. The susceptibility of each strain was determined on two occasions, using parallel E-test and agar dilution methodologies each time. To ensure similar precisions for statistical analyses, E-test MICs were rounded up to a standard twofold agar dilution scale. Clear, elliptical zones were obtained against Staphylococcus spp. M. catarrhalis also gave clear zones, but the scale intercept was often difficult to interpret because of the irregular shape of the inhibition zone. Poor growth sometimes resulted in less-distinct zones of inhibition against Streptococcus spp. and H. influenzae. Excellent correlation was observed between the the E-test and agar dilution against Staphylococcus spp. and H. influenzae, with > 95% of the E-test values falling within one log2 dilution of the corresponding agar MIC. The correlation was lower for Streptococcus spp. and M. catarrhalis, with 86 and 83%, respectively, of E-test results falling within one log2 dilution of the agar MIC. When E-test MICs did not agree exactly with the corresponding agar MIC against Staphylococcus spp. or Streptococcus spp., there was a tendency for the E-test to give a lower MIC. This bias has little effect upon individual MICs in staphylococci or in the generation of susceptibility interpretation errors ( < 1.5% overall), but it could reduce population geometric mean MICs by factors of 0.78 to 0.83. This effect was more marked for Streptococcus spp., reducing the population mean by a factor of 0.73 and resulting in 0.7% major and 8% very major errors. In contrast, the E-test tended to give higher MICs against M. catarrhalis, resulting in 7.3% major errors and increasing the population geometric mean MIC by a factor of 1.60.

Construction management

Construction Management is fundamentally different from other forms of building procurement, including management contracting and should be seen as a 'professional management' service, recognising management as a skill in its own right, aside from contracting. It does expose the client to greater risk, of course, but a value judgement has to be made as to the benefit a client obtains from the system versus the risk profile of the system.

Nova scotia fetal risk project

Family physicians delivering obstetrical care in Nova Scotia were invited to participate in a fetal risk project, conducted from 1971 to 1975. Thirty percent of the physicians participated, and data were collected on 17,270 patients, using the Goodwin, Dunne and Thomas(4) fetal risk scoring system. Patients scoring four to ten on the entire system accounted for 60% of stillbirths and 68% of neonatal deaths; when the 68% of neonatal deaths; when the non-gestational portion alone was used, patients scoring three to six accounted for 52% of stillbirths and 57% of neonatal deaths. When the scoring system was altered, patients scoring three to six accounted for 61% of stillbirths and 62% of neonatal deaths. Patients of participants did not appear to fare better than those of non-participants.

Microinjection of ricin entrapped in unilamellar liposomes into a ricin-resistant mutant of baby hamster kidney cells

Fluorescein-labelled Ricin was entrapped in unilamellar liposomes; 14 microgram of protein was entrapped by 1 mg of lipids. Liposomes added to cells in culture in low serum medium can deliver entrapped Ricin to a Ricin-resistant mutant of baby hamster kidney(BHK)cells. Ricin entrapped in unilamellar liposomes inhibits protein biosynthesis at a concentration of 1.75 microgram/ml in Ricin-resistant cells. Ricin dissolved in medium at 50 microgram/ml does not affect protein synthesis in these cells.
