Protocol of the Australasian Malignant Pleural Effusion-2 (AMPLE-2) trial: A multicentre randomised study of aggressive versus symptom-guided drainage via indwelling pleural catheters

Introduction: Malignant pleural effusions (MPEs) can complicate most cancers, causing dyspnoea and impairing quality of life (QoL). Indwelling pleural catheters (IPCs) are a novel management approach allowing ambulatory fluid drainage and are increasingly used as an alternative to pleurodesis. IPC drainage approaches vary greatly between centres. Some advocate aggressive (usually daily) removal of fluid to provide best symptom control and chance of spontaneous pleurodesis. Daily drainages however demand considerably more resources and may increase risks of complications. Others believe that MPE care is palliative and drainage should be performed only when patients become symptomatic (often weekly to monthly). Identifying the best drainage approach will optimise patient care and healthcare resource utilisation. Methods and analysis: A multicentre, open-label randomised trial. Patients with MPE will be randomised 1:1 to daily or symptom-guided drainage regimes after IPC insertion. Patient allocation to groups will be stratified for the cancer type (mesothelioma vs others), performance status (Eastern Cooperative Oncology Group status 0–1 vs ≥2), presence of trapped lung (vs not) and prior pleurodesis (vs not). The primary outcome is the mean daily dyspnoea score, measured by a 100 mm visual analogue scale (VAS) over the first 60 days. Secondary outcomes include benefits on physical activity levels, rate of spontaneous pleurodesis, complications, hospital admission days, healthcare costs and QoL measures. Enrolment of 86 participants will detect a mean difference of VAS score of 14 mm between the treatment arms (5% significance, 90% power) assuming a common between-group SD of 18.9 mm and a 10% lost to follow-up rate.Ethics and dissemination: The Sir Charles Gairdner Group Human Research Ethics Committee has approved the study (number 2015-043). Results will be published in peer-reviewed journals and presented at scientific meetings

Continuity planning for local public health agencies in northern Wisconsin -- providing essential public health services after displacement

The Continuity Planning in Public Health Survey (CPPHS) was developed to assess the awareness of continuity planning (CP) within the Northwoods Public Health Preparedness Consortium of Northern Wisconsin. Study participants were comprised of 15 females and 2 males. Respondents worked within public health in a managerial or supervisory capacity, with a mean of 10.2 years work experience within their current positions. A total of 17 surveys were analyzed using the Kolmogorov-Smirnov one-sample test for survey item analyses, along with qualitative analyses. Response rate was 77.27%. The Ss assessed: 1) statistical significance in the awareness and implementation of CP, 2) statistical verification regarding the use of CP within preparedness plans, and 3) statistical assessment of public health capacity within the challenges and benefits of CP, following displacement, which is not being able to work from the normal place of business. The data enabled the researcher to qualify trends in responses to answer three research questions. Recommendations are offered for improving awareness and implementation of CP within public health

Clinical outcomes of indwelling pleural catheter-related pleural infections: an international multicenter study

Background: Indwelling pleural catheters (IPCs) offer effective control of malignant pleural effusions (MPEs). IPC-related infection is uncommon but remains a major concern. Individual IPC centers see few infections, and previous reports lack sufficient numbers and detail. This study combined the experience of 11 centers from North America, Europe, and Australia to describe the incidence, microbiology, management, and clinical outcomes of IPC-related pleural infection. Methods: This was a multicenter retrospective review of 1,021 patients with IPCs. All had confirmed MPE. Results: Only 50 patients (4.9%) developed an IPC-related pleural infection; most (94%) were successfully controlled with antibiotics (62% IV). One death (2%) directly resulted from the infection, whereas two patients (4%) had ongoing infectious symptoms when they died of cancer progression. Staphylococcus aureus was the causative organism in 48% of cases. Infections from gram-negative organisms were associated with an increased need for continuous antibiotics or death (60% vs 15% in gram-positive and 25% mixed infections, P = .02). The infections in the majority (54%) of cases were managed successfully without removing the IPC. Postinfection pleurodesis developed in 31 patients (62%), especially those infected with staphylococci (79% vs 45% with nonstaphylococcal infections, P = .04). Conclusions: The incidence of IPC-related pleural infection was low. The overall mortality risk from pleural infection in patients treated with IPC was only 0.29%. Antibiotics should cover S aureus and gram-negative organisms until microbiology is confirmed. Postinfection pleurodesis is common and often allows removal of IPC. Heterogeneity in management is common, and future studies to define the optimal treatment strategies are needed

Protocol of the Australasian Malignant Pleural Effusion (AMPLE) trial: a multicentre randomised study comparing indwelling pleural catheter versus talc pleurodesis

Introduction: Malignant pleural effusion can complicate most cancers. It causes breathlessness and requires hospitalisation for invasive pleural drainages. Malignant effusions often herald advanced cancers and limited prognosis. Minimising time spent in hospital is of high priority to patients and their families. Various treatment strategies exist for the management of malignant effusions, though there is no consensus governing the best choice. Talc pleurodesis is the conventional management but requires hospitalization (and substantial healthcare resources), can cause significant side effects, and has a suboptimal success rate. Indwelling pleural catheters (IPCs) allow ambulatory fluid drainage without hospitalisation, and are increasingly employed for management of malignant effusions. Previous studies have only investigated the length of hospital care immediately related to IPC insertion. Whether IPC management reduces time spent in hospital in the patients' remaining lifespan is unknown. A strategy of malignant effusion management that reduces hospital admission days will allow patients to spend more time outside hospital, reduce costs and save healthcare resources
