A resilient workforce: patient safety and the workforce response to a cyber-attack on the ICT systems of the national health service in Ireland.

BACKGROUND: In May 2021, the Irish public health service was the target of a cyber-attack. The response by the health service resulted in the widespread removal of access to ICT systems. While services including radiology, diagnostics, maternity, and oncology were prioritised for reinstatement, recovery efforts continued for over four months. This study describes the response of health service staff to the loss of ICT systems, and the risk mitigation measures introduced to safely continue health services. The resilience displayed by frontline staff whose rapid and innovative response ensured continuity of safe patient care is explored. METHODS: To gain an in-depth understanding of staff experiences of the cyber-attack, eight focus groups (n = 36) were conducted. Participants from a diverse range of health services were recruited, including staff from radiology, pathology/laboratories, radiotherapy, maternity, primary care dental services, health and wellbeing, COVID testing, older person's care, and disability services. Thematic Analysis was applied to the data to identify key themes. RESULTS: The impact of the cyber-attack varied across services depending on the type of care being offered, the reliance on IT systems, and the extent of local IT support. Staff stepped-up to the challenges and quickly developed and implemented innovative solutions, exhibiting great resilience, teamwork and adaptability, with a sharp focus on ensuring patient safety. The cyber-attack resulted in a flattening of the healthcare hierarchy, with shared decision-making at local levels leading to an empowered frontline workforce. However, participants in this study felt the stress placed on staff by the attack was more severe than the cumulative effect of the COVID-19 pandemic. CONCLUSIONS: Limited contingencies within the health system IT infrastructure - what we call a lack of system resilience - was compensated for by a resilient workforce. Within the context of the prevailing COVID-19 pandemic, this was an enormous burden on a dedicated workforce. The adverse impact of this attack may have long-term and far-reaching consequences for staff wellbeing. Design and investment in a resilient health system must be prioritised.

Variation in resource allocation in urgent and emergency Care Systems in Ireland.

BACKGROUND: A key challenge for most systems is how to provide effective access to urgent and emergency care across rural and urban populations. Tensions about the placement and scope of hospital emergency services are longstanding in Irish political life and there has been recent reform to centralise hospital services in some regions. The focus of this paper is a system approach to examine the geographic variation in resourcing and utilisation of such care across GP practices, out-of-hours care, ambulance services, Emergency Departments and Local Injury Units in Ireland. METHODS: We used a cross-sectional study design to evaluate variation in resource allocation by aggregating geographic funding to various elements of the urgent and emergency care system and assessing patterns in hospital resource utilisation across the population. Expenditure, staffing, access and activity data were gathered from government sources, individual facilities and service providers, health professional bodies, private firms and central statistics. Data on costs and activity in 2014 are collated and presented at both county and regional levels. Analyses focus on resources spent on urgent and emergency care across geographic areas, the role of population concentration in allocation, the relationship between pre-hospital spending and in-hospital spending, and the utilisation of hospital-based emergency care resources by residents of each county. RESULTS: An array of funding mechanisms exists, resulting in a fragmented approach to the resourcing of urgent and emergency care. There are large differences in spending per capita at the county-level, ranging from between €50 and €200 per capita; however, these are less pronounced regionally. Distribution of hospital emergency care resources is highly skewed to the North East of the country, and away from the recently reconfigured South and Mid-West regions. CONCLUSIONS: This analysis advances the traditional approach of evaluating individual services or hospital resourcing. There are notable differences in utilisation of hospital-based emergency care resources at the regional level, indicating that populations within those regions which have been reconfigured have lower utilisation of hospital resources. There is a clear case for more integration in decision-making around funding and consideration of key principles, such as equity, to guide that process.

Case fatality ratios for serious emergency conditions in the Republic of Ireland: a longitudinal investigation of trends over the period 2002-2014 using joinpoint analysis.

BACKGROUND: In the past decade, the Republic of Ireland has undertaken significant reconfiguration programmes to improve emergency services. During this time the public healthcare system experienced a large real decrease in resources. This study assesses national and regional population outcomes over the period 2002-2014, and whether changes coincide with system reconfiguration and the financial restrictions imposed by the 2008 recession. METHODS: Case fatality ratios (CFRs) were constructed for emergency conditions for 2002-2014. Total emergency conditions and individual condition trends were analysed nationally using joinpoint analysis. National results informed the investigation of trends at a regional and county level using an inverse standard error weighted generalised linear model with a log link to construct funnel plots. County-level CFRs were compared for the first and last 3 years of the period to further investigate the changes to county results over the 13 year period, specifically in comparison to the national-level CFR. RESULTS: Nationally, there was an annual fall in CFRs (2.1%). The decline was faster from 2002 to 2007 (annual percentage change = - 3.4; 95% CI-4.4, - 2.4), compared to 2007-2014 (annual percentage change = - 1.2; 95% CI -1.9, - 0.5). The South-East had a lower rate of decrease and the West had a higher rate. Cross sectional analysis of two periods (2002-2004 and 2012-2014) showed high consistency in the counties performance relative to the national CFR in both periods. CONCLUSION: Change in the national trend coincided with the onset of economic stress on the public health system. Attributing the decline in CFR improvement to economic factors is weakened by the uneven nature of the trend change. No distinct pattern of change was identified among regions which underwent substantial reconfiguration of emergency services.

Diffuse pulmonary meningotheliomatosis: a rare cause of multiple pulmonary nodules.

This case describes a woman in her 50s who presented with recurrent lower respiratory tract infections. She was an ex-smoker and had worked on a livestock farm for many years. Chest radiograph and CT of the chest revealed multiple bilateral pulmonary nodules. Bronchoalveolar lavage and transbronchial biopsy did not confirm a unifying diagnosis and thus, surgical biopsy was pursued. Video-assisted thoracoscopic surgical guided biopsy of the right upper, middle and lower lobes demonstrated intraparenchymal minute nodules, consisting of bland epithelioid cells without any evidence of malignancy. The nodules stained positive for neural cell adhesion molecule (CD56) and progesterone receptor with weakly positive epithelial membrane antigen and smooth muscle actin. The combination of this characteristic staining pattern, the diffuse subcentimetre nature of the nodules and this clinical presentation fit with a diagnosis of the ultra-rare pulmonary disease, diffuse pulmonary meningotheliomatosis (DPM). This case highlights a rare cause of bilateral diffuse pulmonary nodules and thus, the breadth of differential diagnoses that need to be considered when approaching such a finding. Careful history-taking and thorough workup is often needed, typically requiring input from multiple specialties. DPM, while rare, should not be overlooked when considering the underlying cause of this presentation, especially in female patients. This case reiterates how common clinical presentations can unveil rare conditions and the contributions of physicians, pathologists and radiologists in the diagnosis and management of these complex diseases.

Interval cancer audit and disclosure in cervical screening programmes: An international survey.

BACKGROUND: Legal cases involving the National Cervical Screening Programme in Ireland following non-disclosure of an interval cervical cancer audit prompted this first international comparative survey of interval cervical cancer audit. METHODS: A survey of 22 international population-based cervical screening programmes was conducted, to determine if they undertook audit of invasive cervical cancers. Those countries/regions that perform reviews were asked (i) how the audit was undertaken, including how the reviews were performed and how they controlled for retrospective bias, (ii) how women are informed of the audit process and how their consent is obtained, and (iii) how audit results were disclosed to patients. RESULTS: Seventeen countries/regions invited completed the survey (77%); 65% (11/17) have an audit process for interval cervical cancers. Five perform individual patient reviews; three perform programme-wide review, with calculation of interval cancer detection rates; one routinely performs programme-wide review with calculation of interval cancer detection rates and offers individual reviews, and one routinely performs local hospital-level reviews. In the remaining country/region, hospital laboratories audit cancers, with a national audit process for all cervical cancers. Varying methodologies for retrospective cytology review were employed; four include control samples, with a ratio varying from 1:1 to 1:2. Three conduct a blinded review. Most countries/regions do not discuss interval cancer audit with participants and 3/11 (27.3%) inform women when a cervical cancer audit takes place. Disclosure is limited and variable. CONCLUSION: The responses suggest that there is no consistent approach to audit of interval cervical cancers or to disclosure of audit results.

Retrospective radiological review and classification of interval breast cancers within population-based breast screening programmes for the purposes of open disclosure: A systematic review.

INTRODUCTION: Interval breast cancers occur following a negative breast screening mammogram and before the next scheduled appointment within screening programmes. Radiological review classifies them as cancers that develop between screens, cancers with no obvious malignant abnormalities on prior screens or cancers not detected at screening. This study aimed to systematically review published literature on the occurrence of open disclosure following interval cancer radiological reviews by breast screening programmes internationally in a retrospective setting and examine methodologies used for radiological reviews for the purposes of disclosure. METHODS: A search for relevant articles published (January 2000 - May 2019) was conducted according to PICO and PRISMA guidelines. The databases Pubmed, Scopus, Google Scholar, Cinahl, Web of Science, Embase, Science Direct and Global Health were searched. Relevant studies were reviewed if they had completed a retrospective review and classification of interval breast cancers. RESULTS: Of 46 relevant articles included, no study was identified that conducted a retrospective review purposely for open disclosure. Retrospective reviews were conducted for audit/quality assurance, and research including for radiologist education and learning. Variation in methodology was found across review type (non-blinded/semi-informed approach), number of reviewers and classification categories. The proportion of false negative cancers classified among the studies ranged from 4 to 40 %. DISCUSSION: Variation among radiological review practices were observed, which likely impacts classification results. To ensure standardised classification of interval breast cancers are employed for the purposes of open disclosure in screening settings, reproducible and consistent methodology is required.

An interrupted time-series analysis of the impact of emergency department reconfiguration on regional emergency department trolley numbers in Ireland from 2005 to 2015.

OBJECTIVES: To understand the impact of emergency department (ED) reconfiguration on the number of patients waiting for hospital beds on trolleys in the remaining EDs in four geographical regions in Ireland using time-series analysis. SETTING: EDs in four Irish regions; the West, North-East, South and Mid-West from 2005 to 2015. PARTICIPANTS: All patients counted as waiting on trolleys in an ED for a hospital bed in the study hospitals from 2005 to 2015. INTERVENTION: The system intervention was the reconfiguration of ED services, as determined by the Department of Health and Health Service Executive. The timing of these interventions varied depending on the hospital and region in question. RESULTS: Three of the four regions studied experienced a significant change in ED trolley numbers in the 12-month post-ED reconfiguration. The trend ratio before and after the intervention for these regions was as follows: North-East incidence rate ratio (IRR) 2.85 (95% CI 2.04 to 3.99, p<0.001), South IRR 0.68 (95% CI 0.51 to 0.89, p=0.006) and the Mid-West IRR 0.03 (95% 1.03 to 2.03, p=0.03). Two of these regions, the South and the Mid-West, displayed a convergence between the observed and expected trolley numbers in the 12-month post-reconfiguration. The North-East showed a much steeper increase, one that extended beyond the 12-month period post-ED reconfiguration. CONCLUSIONS: Findings suggest that the impacts of ED reconfiguration on regional level ED trolley trends were either non-significant or caused a short-term shock which converged on the pre-reconfiguration trend over the following 12 months. However, the North-East is identified as an exception due to increased pressures in one regional hospital, which caused a change in trend beyond the 12-month post reconfiguration.

Drivers of potentially avoidable emergency admissions in Ireland: an ecological analysis.

BACKGROUND: Many emergency admissions are deemed to be potentially avoidable in a well-performing health system. OBJECTIVE: To measure the impact of population and health system factors on county-level variation in potentially avoidable emergency admissions in Ireland over the period 2014-2016. METHODS: Admissions data were used to calculate 2014-2016 age-adjusted emergency admission rates for selected conditions by county of residence. Negative binomial regression was used to identify which a priori factors were significantly associated with emergency admissions for these conditions and whether these factors were also associated with total/other emergency admissions. Standardised incidence rate ratios (IRRs) associated with a 1 SD change in risk factors were reported. RESULTS: Nationally, potentially avoidable emergency admissions for the period 2014-2016 (266 395) accounted for 22% of all emergency admissions. Of the population factors, a 1 SD change in the county-level unemployment rate was associated with a 24% higher rate of potentially avoidable emergency admissions (IRR: 1.24; 95% CI 1.04 to 1.41). Significant health system factors included emergency admissions with length of stay equal to 1 day (IRR: 1.20; 95% CI 1.11 to 1.30) and private health insurance coverage (IRR: 0.92; 95% CI 0.89 to 0.96). The full model accounted for 50% of unexplained variation in potentially avoidable emergency admissions in each county. Similar results were found across total/other emergency admissions. CONCLUSION: The results suggest potentially avoidable emergency admissions and total/other emergency admissions are primarily driven by socioeconomic conditions, hospital admission policy and private health insurance coverage. The distinction between potentially avoidable and all other emergency admissions may not be as useful as previously believed when attempting to identify the causes of regional variation in emergency admission rates.

Development of performance indicators for systems of urgent and emergency care in the Republic of Ireland: Systematic review and consensus development exercise.

Objectives: To develop a set of performance indicators to monitor the performance of emergency and urgent care systems in the Republic of Ireland. Design: This study comprised of an update of a previously performed systematic review and a formal consensus development exercise. Results: Initial literature searches yielded 2339 article titles.  After further searches, sixty items were identified for full-text review. Following this review, fifty-seven were excluded. Three articles were identified for inclusion in the systematic review. These papers produced 42 unique indicators for consideration during the consensus development exercise. In total, 17 indicators had a median of greater than 7 following the meeting and met our pre-specified criterion for acceptable consensus. Discussion: Using this systematic review and nominal group consensus development exercise, we have identified a set of 17 indicators, which a consensus of different experts regard as potentially good measures of the performance of urgent and emergency care systems in Ireland.

Patient experience of different regional models of urgent and emergency care: a cross-sectional survey study.

OBJECTIVES: To compare user experiences of 8 regional urgent and emergency care systems in the Republic of Ireland, and explore potential avenues for improvement. DESIGN: A cross-sectional survey. SETTING: Several distinct models of urgent and emergency care operate in Ireland, as system reconfiguration has been implemented in some regions but not others. The Urgent Care System Questionnaire was used to explore service users' experiences with urgent and emergency care. Linear regression and logistic regression were used to detect regional variation in each of the 3 domains and overall ratings of care. PARTICIPANTS: A nationally representative sample (N=8002) of the general population was contacted by telephone, yielding 1205 participants who self-identified as having used urgent and emergency care services in the previous 3 months. MAIN OUTCOME MEASURES: Patient experience was assessed across 3 domains: entry into the system, progress through the system and patient convenience of the system. Participants were also asked to provide an overall rating of the care they received. RESULTS: Service users in Dublin North East gave lower ratings on the entry into the system scale than those in Dublin South (adjusted mean difference=-0.18; 95% CI -0.35 to -0.10; p=0.038). For overall ratings of care, service users in the Mid-West were less likely than those in Dublin North East to give an excellent rating (adjusted OR 0.57; 95% CI 0.35 to 0.92; p=0.022). Survey items relating to communication, and consideration of patients' needs were comparatively poorly rated. The use of public emergency departments and out-of-hours general practice care was associated with poorer patient experiences. CONCLUSIONS: No consistent relationship was found between the type of urgent and emergency care model in different regions and patient experience. Scale-level data may not offer a useful metric for exploring the impact of system-level service change.

Understanding perspectives on major system change: A comparative case study of public engagement and the implementation of urgent and emergency care system reconfiguration.

OBJECTIVES: Major changes have been made to how emergency care services are configured in several regions in the Republic of Ireland. This study investigated the hypothesis that engagement activities undertaken prior to these changes influenced stakeholder perspectives on the proposed changes and impacted on the success of implementation. METHODS: A comparative case-study approach was used to explore the changes in three regions. These regions were chosen for the case study as the nature of the proposals to reconfigure care provision were broadly similar but implementation outcomes varied considerably. Documentary analysis of reconfiguration planning reports was used to identify planned public engagement activities. Semi-structured interviews with 74 purposively-sampled stakeholders explored their perspectives on reconfiguration, engagement activities and public responses to reconfiguration. Framework analysis was used, integrating inductive and deductive approaches. RESULTS: Approaches to public engagement and success of implementation differed considerably across the three cases. Regions that presented the public with the reconfiguration plan alone reported greater public opposition and difficulty in implementing changes. Engagement activities that included a range of stakeholders and continued throughout the reconfiguration process appeared to largely address public concerns, contributing to smoother implementation. CONCLUSIONS: The presentation of reconfiguration reports alone is not enough to convince communities of the case for change. Genuine, ongoing and inclusive engagement offers the best opportunity to address community concerns about reconfiguration.
