An advanced systemic lesson learned knowledge model for project organisations

The research study described in this thesis was inspired by many years as a project manager, watching the failure of organisation projects, and the lessons learned. This led to the research idea of how can the lessons learned enable organisations to learn from past project experiences to drive continuous improvement. The thesis is based on five published publications that collectively make a significant contribution to knowledge of the development of the Systemic Lessons Learned Knowledge (Syllk) model (Paper One) and application of the Syllk model (Papers Two, Three and Four) and the research methodology (Paper Five). I have applied an action research study which addressed the dual imperatives of both the research and problem solving by using a series of action research cycles on three separate projects. The research method consisted of multiple spiral action research cycles. I have demonstrated how to apply the Syllk model to enable the organisations to disseminate and apply knowledge/lessons learned. The initial planning stage consisted of interviews, followed by focus groups, to identify the facilitators and barriers that impact upon the initial design of the Syllk model within the organisation. Established knowledge management practices were aligned with each of the Syllk elements to address the identified barriers and facilitate learning as the action cycles progressed. Initiatives were implemented, and actions were observed, monitored, and then evaluated after a period of reflection using an after-action review process. The results from this research showed how knowledge capability can be wired (distributed) across organisational systems (capability networked) and how the Syllk model can be used to conceptually facilitate this. The research study described in this thesis provides insights into how an organisation learns and how it can be effectively wired to acquire and accumulate knowledge, including from lessons learned. The thesis highlights that the variables of the Syllk model (learning, culture, social, technology, process and infrastructure) were found to be the most dynamic and influential for the organisation participating in the action research. The action research outcomes showed that an organisation is not a simple structure, but rather, a complex interweaving and coupling (capability network) of the Syllk elements of people and systems. Processes in the organisation need to align with the elements of the Syllk model. Using action research is one possible way forward. One needs to understand how the organisation is wired for knowledge and lessons learned. The findings from this research form a sound structure for future research studies based on the application of the Syllk model. This research supports the premise that to successfully manage projects and day-to-day business activities, the learning process is challenged by many barriers. The thesis demonstrates that action research can benefit project management and knowledge management researchers and practitioners

The adverse impact of COVID-19 pandemic on cardiovascular disease prevention and management in England, Scotland and Wales: A population-scale analysis of trends in medication data

Objectives To estimate the impact of the COVID-19 pandemic on cardiovascular disease (CVD) and CVD management using routinely collected medication data as a proxy. Design Descriptive and interrupted time series analysis using anonymised individual-level population-scale data for 1.32 billion records of dispensed CVD medications across 15.8 million individuals in England, Scotland and Wales. Setting Community dispensed CVD medications with 100% coverage from England, Scotland and Wales, plus primary care prescribed CVD medications from England (including 98% English general practices). Participants 15.8 million individuals aged 18+ years alive on 1 st April 2018 dispensed at least one CVD medicine in a year from England, Scotland and Wales. Main outcome measures Monthly counts, percent annual change (1 st April 2018 to 31 st July 2021) and annual rates (1 st March 2018 to 28 th February 2021) of medicines dispensed by CVD/ CVD risk factor; prevalent and incident use. Results Year-on-year change in dispensed CVD medicines by month were observed, with notable uplifts ahead of the first (11.8% higher in March 2020) but not subsequent national lockdowns. Using hypertension as one example of the indirect impact of the pandemic, we observed 491,203 fewer individuals initiated antihypertensive treatment across England, Scotland and Wales during the period March 2020 to end May 2021 than would have been expected compared to 2019. We estimated that this missed antihypertension treatment could result in 13,659 additional CVD events should individuals remain untreated, including 2,281 additional myocardial infarctions (MIs) and 3,474 additional strokes. Incident use of lipid-lowering medicines decreased by an average 14,793 per month in early 2021 compared with the equivalent months prior to the pandemic in 2019. In contrast, the use of incident medicines to treat type-2 diabetes (T2DM) increased by approximately 1,642 patients per month. Conclusions Management of key CVD risk factors as proxied by incident use of CVD medicines has not returned to pre-pandemic levels in the UK. Novel methods to identify and treat individuals who have missed treatment are urgently required to avoid large numbers of additional future CVD events, further adding indirect cost of the COVID-19 pandemic

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
