    Abstract Objectives: To investigate the information seeking behaviors and response to the HIN1 outbreak by limited-English proficient (LEP) Chinese speakers.
    Methods: We conveniently sampled 100 adult Chinese LEP individuals between June 2 and June 11, 2009, during the time the World Health Organization (WHO) declared global pandemic alert level at phase 6 and the development of a H1N1 vaccine was still underway.
    Results: Participants demonstrated a basic understanding of the disease and were unconcerned by the outbreak. Major channels for HIN1 information included watching TV (81 percent), reading Chinese newspaper (69 percent), and community-based organization (30 percent). Only 2 percent obtained information from a public health system or hotline. The odds of being informed of timely HIN1 information were significantly higher for participants who did not speak English at all than those who reported speaking English "not well"(OR = 2.65; CI:1.04, 7.01).
    Conclusions: LEP Chinese speakers seem acknowledged for this outbreak. However, scarce use of the local public health system to obtain H1N1 information suggests more work needs to be done to reach out to the LEP community to enhance their capacity to respond to future outbreaks.

    Abstract Introduction: We examined whether the United Kingdom (UK) or the United States (US) screening criteria are more appropriate for retinopathy of prematurity (ROP) screening in Hong Kong, in terms of sensitivity for detecting type 1 ROP and the number of infants requiring screening.
    Methods: In this retrospective cohort study, we reviewed the medical records of all infants who underwent ROP screening from 2009 to 2018 at a tertiary hospital in Hong Kong. During this period, all infants born at gestational age (GA) ≤31 weeks and 6 days or birth weight (BW) <1501 g (ie, the UK screening criteria) underwent ROP screening. We determined the number of infants requiring screening and the number of type 1 ROP cases that would have been missed if the US screening criteria (GA ≤30 weeks & 0 days or BW ≤1500 g) had been used.
    Results: Overall, 796 infants were screened using the UK screening criteria. If the US screening criteria had been used, the number of infants requiring screening would have decreased by 21.1%; all type 1 ROP cases would have been detected (38/38, 100% sensitivity). Of the 168 infants who would not have been screened using the US screening criteria, only four of them (2.4%) had developed ROP (all maximum stage 1 only).
    Conclusion: In our population, the use of the US screening criteria could reduce the number of infants screened without compromising sensitivity for the detection of type 1 ROP requiring treatment. We suggest narrowing the GA criterion for consistency with the US screening criteria during ROP screening in Hong Kong.

    Abstract Aims: To assess the cost-effectiveness of carbetocin versus oxytocin for the prevention of postpartum hemorrhage (PPH) following vaginal birth from the perspective of the UK National Health Service (NHS).
    Materials and methods: A decision tree model was designed to analyze the cost per PPH event avoided associated with utilizing carbetocin versus oxytocin for prophylactic treatment of PPH in women following vaginal birth from a UK perspective. It modelled the potential for women to require an additional uterotonic after prophylaxis, and to still experience a PPH event and receive associated treatment. Inpatient recovery and follow-up periods post-PPH were also included in the model. Costs associated with drug acquisition and administration, PPH management (i.e. additional staffing and possible operating theater and high dependency unit utilization), inpatient hospitalization, and follow-up visits were all considered. Adverse event management costs were not included. Resource utilization varied depending on the severity of the PPH event (as defined by the amount of blood lost). PPH events avoided were estimated. In an exploratory analysis, quality adjusted life years (QALYs) were estimated as well.
    Results: In the deterministic base case, costs were £55 lower and PPH events were 0.0342 lower per woman with carbetocin use compared to oxytocin use. Across the cohort of 100 women the reduction in PPH events led to the largest cost savings (£4,233 saved) out of all cost categories, with total cost savings of £5,495. Carbetocin utilization amongst the entire cohort led to 3.42 avoided PPH events compared to oxytocin utilization, comprised of 3.03 fewer mild/moderate PPH events and 0.39 fewer severe PPH events. Carbetocin utilization led to 0.0001 additional QALYs per woman.
    Conclusion: Carbetocin utilization leads to lower prophylactic treatment costs and less PPH events versus oxytocin when utilized for the prevention of PPH following vaginal birth in the UK.

    Abstract Background: There is little evidence available regarding the impact of Achilles Tendinopathy (AT) on health-related quality of life (HRQOL). The primary aim of this study was to quantify the clinical and health-related quality-of-life patient-reported outcome measures for a population presenting with either mid-substance or insertional Achilles tendinopathy.
    Methods: A prospective comparative observational study of consecutive patients with AT presenting for extracorporeal shockwave therapy (ESWT) at a large teaching hospital. The primary outcome was assessment of a validated health-related quality of life PROMs (Euroqol EQ-5D-5L) and comparison to 2 general UK population datasets. The secondary outcomes were Visual Analogue Pain Scale (VAS-Pain) and two validated foot-specific patient reported outcome measures (Foot Function Index (FFI) and Victorian Institute of Sports Assessment-Achilles (VISA-A)).
    Results: Between March 2014 and June 2021, 320 consecutive patients (125 male; 195 female) were diagnosed with AT and referred for a first course of ESWT. EQ-5D-5L PROMs were prospectively collected for 303 of these patients (94.7%). The mean age (± standard deviation(SD)) was 52.1 ± 11.4 years. The mean EQ-5D-5L Index score (mean±SD) for the AT cohort was 0.783 ± 0.131. Patients less than 55 years with AT had a statistically significantly worse quality of life compared with members of the same age group in the general population. The mean VAS-Pain, FFI, VISA-A clinical outcome scores were 6.0 ± 2.3, 49.5 ± 21.2 and 34.1 ± 14.4 respectively. There was a statistically significant moderate correlation between HRQOL and clinical PROMs (VAS-Pain and FFI vs EQ-5D) however there was no correlation with age.
    Conclusion: This study demonstrates that patients under the age of 55 with AT have a significantly reduced quality of life compared with the general population.

    Abstract Objectives: Atezolizumab monotherapy has marketing authorisation by the Medicines and Healthcare products Regulatory Agency as adjuvant treatment following complete resection for adults with stage II-IIIA non-small cell lung cancer (NSCLC) whose tumours have PD-L1 expression on ≥ 50% of tumour cells and whose disease has not progressed following adjuvant platinum-based chemotherapy. This study evaluated the cost-effectiveness of atezolizumab vs best supportive care (BSC) in the licensed patient population from a UK perspective.
    Materials and methods: Patient characteristics and clinical inputs were derived from the global, randomised, open-label, phaseIII IMpower010 trial. A Markov model with the following health states was developed: disease-free survival (DFS), locoregional recurrence, first-line metastatic recurrence, second-line metastatic recurrence, and death (all partitioned based on receipt of treatment, excluding death). The base case model used a lifetime time horizon (40 years) and 3.5% discounting annually after the first year. DFS from IMpower010 was analysed with parametric survival models to extrapolate outcomes for time points beyond trial follow-up. The models were adjusted to avoid overestimating results for patients with recurrences in the longer term. Grade ≥ 3 treatment-related adverse events with incidences ≥ 2% were included. Health state utility values were derived from the literature and past NICE appraisals. Sensitivity and scenario analyses assessed uncertainty around assumptions and parameter estimates.
    Results: In the base case analysis, atezolizumab therapy resulted in an expected gain of 1.87 quality-adjusted life-years (QALYs) corresponding to an incremental cost-effectiveness ratio of £20,392/QALY for atezolizumab vs BSC, demonstrating cost-effectiveness. Results were most influenced by discount effects and utility in the on-treatment DFS state. Scenario analyses were consistent with the base case results.
    Conclusion: Atezolizumab after adjuvant chemotherapy is cost-effective for adults with NSCLC in the UK.

    Abstract Melioidosis has protean manifestations and often mimics other disease processes. We present a case of a gentleman presenting with chronic cough whose initial radiographic findings of a cavitatory lung lesion and mediastinal lymphadenopathy were suggestive of tuberculosis. This case highlights the important role that bronchoscopy and endobronchial ultrasound can play in the diagnosis of melioidosis in patients presenting with mediastinal lymphadenopathy whose initial microbiological findings from sputum are negative for tuberculosis.
