Abstract

Point-of-care tests (POCT) allow for near patient or bedside tests that provide instant or rapid results that facilitate real time clinical decision making within patient pathways. Advances in technology has lead to more POCT becoming available and therefore an efficient evaluation process is required to identify the tests that bring demonstrable benefits to patients and society. This thesis provides a novel evidence-based toolkit for the multi-dimensional assessment of POCT that aims to improve the efficiency of the evidence generation process and increase the uptake of POCT devices into clinical practice where their impact can be realised. This is achieved through the development of an overarching framework, the point-of-care key evidence tool (POCKET). This generalisable checklist, developed through a mixed method approach, incorporating relevant POCT stakeholders, facilitates the robust reporting of POCT evaluation by outlining the evidence that is required for adoption by policy and decision makers. Public and patient engagement is a fundamental component of healthcare research and particularly important in the evaluation of POCT to ensure tests are acceptable to patients. To improve this process in the evaluation of POCT two innovative tools were piloted. Sequential simulation (SqS) of clinical pathways was used to demonstrate the downstream pathway implications of incorporating a POCT and the HT-36 questionnaire was created to measure the impact to life of home POCT for patients. This information will allow meaningful comparisons between different devices and inform device design. Finally, evidence alone is not enough to justify the adoption of POCT and barriers and facilitators exist. These factors are determined through the analysis of stakeholder interviews with the same methodology being applied to a case study to understand the barriers that apply to a specific device and develop mitigating strategies. The thesis concludes with an algorithm to guide the approach to the evaluation of POCT.

Abstract

Objective:To identify the most prevalent symptoms and those with greatest impact upon health-related quality of life (HRQOL) among esophageal cancer survivors.Background:Long-term symptom burden after esophagectomy, and associations with HRQOL, are poorly understood.Patients and Methods:Between 2010 and 2016, patients from 20 European Centers who underwent esophageal cancer surgery, and were disease-free at least 1 year postoperatively were asked to complete LASER, EORTC-QLQ-C30, and QLQ-OG25 questionnaires. Specific symptom questionnaire items that were associated with poor HRQOL as identified by EORTC QLQ-C30 and QLQ-OG25 were identified by multivariable regression analysis and combined to form a tool.Results:A total of 876 of 1081 invited patients responded to the questionnaire, giving a response rate of 81%. Of these, 66.9% stated in the last 6 months they had symptoms associated with their esophagectomy. Ongoing weight loss was reported by 10.4% of patients, and only 13.8% returned to work with the same activities.Three LASER symptoms were correlated with poor HRQOL on multivariable analysis; pain on scars on chest (odds ratio (OR) 1.27; 95% CI 0.97-1.65), low mood (OR 1.42; 95% CI 1.15-1.77) and reduced energy or activity tolerance (OR 1.37; 95% CI 1.18-1.59). The areas under the curves for the development and validation datasets were 0.81 ± 0.02 and 0.82 ± 0.09 respectively.Conclusion:Two-thirds of patients experience significant symptoms more than 1 year after surgery. The 3 key symptoms associated with poor HRQOL identified in this study should be further validated, and could be used in clinical practice to identify patients who require increased support.

Abstract

Laparoscopic cholecystectomy is the gold standard method for treating gallstone related disease. Despite its widespread and well established application, clear consensus is not arrived at regarding the comparative risks and benefits of acute versus interval cholecystectomy. The complications of this technique are well known, with respect to both the operative intervention and the technique used. This case describes a case of cholecystitis in a 76-year-old man, who underwent acute laparoscopic cholecystectomy for cholecystitis refractory to antibiotic therapy. Postoperative complications included subhepatic collections bilaterally, eventually leading to the formation of an enterocutaneous fistula to the left chest wall - a previously undocumented phenomenon. The protracted course of the disease is discussed, with reference to investigations performed and the eventual successful outcome.

Abstract

Objective To determine if use of point of care testing (POCT) is less costly than laboratory testing to the National Health Service (NHS) in delivering the NHS Health Check (NHSHC) programme in the primary care setting. Design Observational study and theoretical mathematical model with microcosting approach. Setting We collected data on NHSHC delivered at nine general practices (seven using POCT; two not using POCT). Participants We recruited nine general practices offering NHSHC and a pathology services laboratory in the same area. Methods We conducted mathematical modelling with permutations in the following fields: provider type (healthcare assistant or nurse), type of test performed (total cholesterol with either lab fasting glucose or HbA1c), cost of consumables and variable uptake rates, including rate of non-response to invite letter and rate of missed [did not attend (DNA)] appointments. We calculated total expected cost (TEC) per 100 invites, number of NHSHC conducted per 100 invites and costs for completed NHSHC for laboratory and POCT-based pathways. A univariate and probabilistic sensitivity analysis was conducted to account for uncertainty in the input parameters. Main outcome measures We collected data on cost, volume and type of pathology services performed at seven general practices using POCT and a pathology services laboratory. We collected data on response to the NHSHC invitation letter and DNA rates from two general practices. Results TEC of using POCT to deliver a routine NHSHC is lower than the laboratory-led pathway with savings of £29 per 100 invited patients up the point of cardiovascular disease risk score presentation. Use of POCT can deliver NHSHC in one sitting, whereas the laboratory pathway offers patients several opportunities to DNA appointment. Conclusions TEC of using POCT to deliver an NHSHC in the primary care setting is lower than the laboratory-led pathway. Using POCT minimises DNA rates associated with laboratory testing and enables completion of NHSHC in one sitting.

Abstract

Introduction Point-of-care in vitro diagnostics (POC-IVD) are increasingly becoming widespread as an acceptable means of providing rapid diagnostic results to facilitate decision-making in many clinical pathways. Evidence in utility, usability and cost-effectiveness is currently provided in a fragmented and detached manner that is fraught with methodological challenges given the disruptive nature these tests have on the clinical pathway. The Point-of-care Key Evidence Tool (POCKET) checklist aims to provide an integrated evidence-based framework that incorporates all required evidence to guide the evaluation of POC-IVD to meet the needs of policy and decisionmakers in the National Health Service (NHS). Methods and analysis A multimethod approach will be applied in order to develop the POCKET. A thorough literature review has formed the basis of a robust Delphi process and validation study. Semistructured interviews are being undertaken with POC-IVD stakeholders, including industry, regulators, commissioners, clinicians and patients to understand what evidence is required to facilitate decision-making. Emergent themes will be translated into a series of statements to form a survey questionnaire that aims to reach a consensus in each stakeholder group to what needs to be included in the tool. Results will be presented to a workshop to discuss the statements brought forward and the optimal format for the tool. Once assembled, the tool will be field-tested through case studies to ensure validity and usability and inform refinement, if required. The final version will be published online with a call for comments. Limitations include unpredictable sample representation, development of compromise position rather than consensus, and absence of blinding in validation exercise. Ethics and dissemination The Imperial College Joint Research Compliance Office and the Imperial College Hospitals NHS Trust R&D department have approved the protocol. The checklist tool will be disseminated through a PhD thesis, a website, peer-reviewed publication, academic conferences and formal presentations.

Abstract

Background: This study aimed to develop the Point-of-Care Key Evidence Tool (POCKET); a multi-dimensional checklist to guide the evaluation of point-of-care tests (POCTs) incorporating validity, utility, usability, cost-effectiveness and patient experience. The motivation for this was to improve the efficiency of evidence generation in POCTs and reduce the lead-time for the adoption of novel POCTs. Methods: A mixed qualitative and quantitative approach was applied. Following a literature search, a three round Delphi process was undertaken incorporating a semi-structured interview study and two questionnaire rounds. Participants included clinicians, laboratory personnel, commissioners, regulators (including members of National Institute for Health and Care Excellence [NICE] committees), patients, industry representatives and methodologists. Qualitative data were analysed based on grounded theory. The final tool was revised at an expert stakeholder workshop. Results: Forty-three participants were interviewed within the semi-structured interview study, 32 participated in the questionnaire rounds and nine stakeholders attended the expert workshop. The final version of the POCKET checklist contains 65 different evidence requirements grouped into seven themes. Face validity, content validity and usability has been demonstrated. There exists a shortfall in the evidence that industry and research methodologists believe should be generated regarding POCTs and what is actually required by policy and decision makers to promote implementation into current healthcare pathways. Conclusions: This study has led to the development of POCKET, a checklist for evidence generation and synthesis in POCTs. This aims to guide industry and researchers to the evidence that is required by decision makers to facilitate POCT adoption so that the benefits they can bring to patients can be effectively realised.
