Screening success: A virtual MDT can reduce the number of patients requiring respiratory follow-up post-COVID-19 pneumonia in line with British Thoracic Society guidance.

Introduction and objectivesThe ongoing respiratory sequelae of COVID-19 pneumonia remain unclear, and the ideal follow-up of these patients is still a work in progress. We describe our experience of using a pre-follow-up multidisciplinary team (MDT) to decide the follow-up stream in patients hospitalised for COVID-19 pneumonia. METHODS: We reviewed all patients with a clinico-radiological diagnosis of COVID-19 admitted to hospital during a 3-month period and assigned a follow-up stream based on British Thoracic Society guidance. RESULTS: We changed the follow-up pathway in 71% (277/392) and refined the pathway in 67% (261/392) of indeterminate cases. We also created an automated process for the general practitioner to book follow-up imaging and will use this process going forward. CONCLUSION: These findings highlight the importance of the MDT review of cases with suspected COVID-19 pneumonia prior to clinic attendance to ensure appropriate patients are followed up and to optimise utilisation of outpatient imaging and clinics.

Automated calculation of the right ventricle to left ventricle ratio on CT for the risk stratification of patients with acute pulmonary embolism.

OBJECTIVES: To assess the feasibility and reliability of the use of artificial intelligence post-processing to calculate the RV:LV diameter ratio on computed tomography pulmonary angiography (CTPA) and to investigate its prognostic value in patients with acute PE. METHODS: Single-centre, retrospective study of 101 consecutive patients with CTPA-proven acute PE. RV and LV volumes were segmented on 1-mm contrast-enhanced axial slices and maximal ventricular diameters were derived for RV:LV ratio using automated post-processing software (IMBIO LLC, USA) and compared to manual analysis in two observers, via intraclass coefficient correlation analysis. Each CTPA report was analysed for mention of the RV:LV ratio and compared to the automated RV:LV ratio. Thirty-day all-cause mortality post-CTPA was recorded. RESULTS: Automated RV:LV analysis was feasible in 87% (n = 88). RV:LV ratios ranged from 0.67 to 2.43, with 64% (n = 65) > 1.0. There was very strong agreement between manual and automated RV:LV ratios (ICC = 0.83, 0.77-0.88). The use of automated analysis led to a change in risk stratification in 45% of patients (n = 40). The AUC of the automated measurement for the prediction of all-cause 30-day mortality was 0.77 (95% CI: 0.62-0.99). CONCLUSION: The RV:LV ratio on CTPA can be reliably measured automatically in the majority of real-world cases of acute PE, with perfect reproducibility. The routine use of this automated analysis in clinical practice would add important prognostic information in patients with acute PE. KEY POINTS: • Automated calculation of the right ventricle to left ventricle ratio was feasible in the majority of patients and demonstrated perfect intraobserver variability. • Automated analysis would have added important prognostic information and altered risk stratification in the majority of patients. • The optimal cut-off value for the automated right ventricle to left ventricle ratio was 1.18, with a sensitivity of 100% and specificity of 54% for the prediction of 30-day mortality.

Evaluating the impact of nurse practitioner involvement in a pleural procedures clinic.

BACKGROUND: Pleural disease incidence is increasing and there has been a move towards outpatient management. Pleural clinics have been developed for patients to be assessed and have pleural procedures for diagnostic and symptomatic purposes. AIM: The study aimed to assess the impact of nurse practitioner (NP) involvement in a pleural procedures clinic on clinic capacity, and staff and patient experience. METHODS: A mixed-methods service evaluation was completed in a medium-sized general hospital. The number of patients seen in clinic over a 6-month period at the beginning of NP involvement was compared with the number of patients seen 1 year later. Semi-structured interviews of key staff stakeholders were conducted. FINDINGS: Clinic capacity increased from 4.57 to 5.86 patients per list. NP involvement increased access, improved patient care, reduced work burden for other staff and improved educational opportunities. CONCLUSION: The impact of NP involvement in the pleural clinic was seen as positive and increased clinic capacity. The same model of practice could be considered elsewhere.
