How do we conduct a national transfusion related lookback program?

BACKGROUND: Lookback investigations are conducted by blood services when a risk of transmission of infection from a donor to a recipient has been identified. They involve tracing transfusion recipients and offering them testing for the relevant infectious agent. Results are relayed to the recipient to provide reassurance that there has been no transmission or to ensure appropriate treatment and care if required, and blood services are able to learn lessons from the planning, delivery, and outcomes of the investigation. A national lookback exercise was conducted in Scotland following the introduction of a test to identify occult hepatitis B infection, as recommended by the UK Advisory Committee for the Safety of Blood, Tissues and Organs (SaBTO) in 2021. METHODS AND MATERIALS: This paper outlines the development and delivery of a national lookback program. It discusses the logistical, economic, ethical, regulatory, and scientific issues that were considered during the planning and delivery of the lookback exercise. RESULTS: Development and delivery of a national lookback required robust governance, engagement of all relevant stakeholders and a shared understanding of aims, effective communication, systems, resources, limitations, and project management. Outcomes included a high testing uptake, low levels of reported anxiety, and a comprehensive data set. CONCLUSION: Key aspects for delivery of a successful large-scale lookback program include a patient-centered approach, clear and accessible communication, and whole-systems multiagency collaboration. Major challenges include stakeholder engagement and capacity.

What are the similarities and differences in lung cancer symptom appraisal and help-seeking according to smoking status? A qualitative study with lung cancer patients.

OBJECTIVE: Lung cancer in never-smokers represents a growing proportion of patients. The relationship between smoking status, symptom appraisal and help-seeking behaviour is complex. Little is known about cancer symptom-related health behaviours according to smoking status. The aim of the study was to explore lung cancer patients' experiences of a lung cancer diagnosis, identifying differences by smoking history. METHOD: This was a qualitative study involving telephone interviews with 40 lung cancer patients (20 never smokers, 11 former smokers and 9 current smokers). We used framework analysis to analyse the data using the Common Sense Model of Illness Self-Regulation as a theoretical framework, developed after initial analysis. RESULTS: All patients were likely to delay seeking help for symptoms in primary care regardless of smoking history, but for different reasons. Smoking history was instrumental to how individuals perceived and responded to early symptoms of lung cancer. Differences in interpretation and coping responses to new symptoms seemed to be caused by the higher presence of comorbidities due to smoking, and perceptions of the current state of health. Individuals with a smoking history reported acting with urgency in seeking help and follow up, whereas patients who experienced low levels of concern were more easily reassured by clinicians, resulting in delays. CONCLUSIONS: Never and former smokers perceive, interpret, and respond to symptoms of lung cancer differently to smokers. However, few people attribute their lung symptoms to cancer initially, even with a smoking history. Interventions that drive increased urgency and vigilance in never smokers may be effective.

Hepatitis A-2017 an unusual year in Scotland.

BACKGROUND: The number of cases of acute hepatitis A reported in Scotland each year is small, and the majority of cases have been associated with travel to endemic regions. However, in early 2017, in the midst of ongoing outbreaks of hepatitis A among MSM in Europe, there was a sharp rise in the number of cases reported to Health Protection Scotland. OBJECTIVES: The initial aim of this study was to investigate the reason for the observed increase in cases of hepatitis A at the start of 2017. As cases continued for the remainder of the year, these cases were typed to determine whether these cases were linked to each other, or other outbreaks. STUDY DESIGN: The study population consisted of 42 hepatitis A infected patients with no obvious source of infection. The patient samples were collected between January and December 2017. The VP1/2 A region was amplified and sequenced. RESULTS: The majority of samples typed as genotype 1 A (n = 17) or genotype 1B (n = 15). Within genotype 1 A, fifteen samples had strains (VRD_521_2016 or RIVM_HAV16_090) associated with ongoing outbreaks of hepatitis A in MSM in Europe. Within genotype 1B, there were four clusters of infections, with identical cases in geographically distinct regions with no identified epidemiological link. CONCLUSIONS: Molecular typing proved useful, as it allowed public health to identify clusters, establish links with other outbreaks and compare Scottish strains with those reported elsewhere.
