Impact of cystic fibrosis multidisciplinary virtual clinics on patient experience, time commitments and costs.

BACKGROUND AND AIMS: The experience of outpatient care may differ for select patient groups. This prospective study evaluates the adult patient experience of multidisciplinary outpatient cystic fibrosis (CF) care with videoconferencing through telehealth compared with face-to-face care the year prior. METHODS: People with CF without a lung transplant were recruited. Patient-reported outcomes were obtained at commencement and 12 months into the study, reflecting both their face-to-face and telehealth through videoconferencing experience, respectively. Three patient cohorts were analysed: (i) participants with a regional residence, (ii) participants with a nonregional including metropolitan residence and (iii) participants with colonised multiresistant microbiota. RESULTS: Seventy-four patients were enrolled in the study (mean age, 37 ± 11 years; 50% male; mean forced expiratory volume in the first second of expiration, 60% [standard deviation, 23]) between February 2020 and May 2021. No differences between models were observed in the participants' rating of the health care team, general and mental health rating, and their confidence in handling treatment plans at home. No between-group differences in the Cystic Fibrosis Questionnaire - Revised (CFQ-R) were observed. Travel duration and the cost of attending a clinic was significantly reduced, particularly for the regional group (4 h, AU$108 per clinic; P < 0.05). A total of 93% respondents preferred to continue with a hybrid approach. CONCLUSION: In this pilot study, participants' experience of care and quality of life were no different with face-to-face and virtual care between the groups. Time and cost-savings, particularly for patients living in regional areas, were observed. Most participants preferred to continue with a hybrid model for outpatient care.

Use of extracorporeal membrane oxygenation in cystic fibrosis in an Australian cystic fibrosis centre.

Extracorporeal membrane oxygenation (ECMO) support is used in selected patients with cystic fibrosis (CF) as a bridge to transplantation. Our aim was to describe briefly treatment and outcomes of six CF patients who received ECMO. One patient received a lung transplant and another recovered from acute respiratory failure. Four died despite ECMO support. Lack of timely availability of suitable donor lungs and patient selection are contributing factors.

Quality of home spirometry performance amongst adults with cystic fibrosis.

Spirometry is usually performed under the supervision of a trained respiratory scientist to ensure acceptability and repeatability of results. To evaluate the quality of spirometry performance by adult cystic fibrosis (CF) patients with and without observation by a trained respiratory scientist, an observational, single centre study was conducted between February to December 2020. 74 adults were recruited and instructed to perform spirometry without supervision within 24 h of their remote CF clinic consultation. Spirometry was repeated at their consultation, supervised by a respiratory scientist using video conferencing. The majority of patients achieved grade A (excellent) or B (very good) spirometry quality with (95%) and without supervision (93%) independent of lung function severity. Similarly, forced expiratory volume in 1 second demonstrated no significant differences with paired spirometry performed within a 24 hour period. For a large proportion of adult CF patients, unsupervised portable spirometry produces acceptable and repeatable results.

Combination antibiotic susceptibility testing to treat exacerbations of cystic fibrosis associated with multiresistant bacteria: a randomised, double-blind, controlled clinical trial.

BACKGROUND: We did a randomised, double-blind, controlled clinical trial to prospectively assess whether use of combination antibiotic susceptibility testing improved clinical outcomes in patients with acute pulmonary exacerbations of cystic fibrosis who were infected with multiresistant bacteria. METHODS: 251 patients with cystic fibrosis who were chronically infected with multiresistant gram negative bacteria gave sputum at 3-month intervals for conventional culture and sensitivity tests and for combination antibiotic susceptibility tests using multiple combination bactericidal antibiotic testing (MCBT). Patients who developed an exacerbation of pulmonary disease were randomised to receive a 14-day course of any two blinded intravenous antibiotics chosen on the basis of either results from conventional sputum culture and sensitivity testing or the result of MCBT. The primary outcome was time from randomisation until the patient's next pulmonary exacerbation. Analysis was by intention-to-treat. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN60187870. FINDINGS: 132 patients had a pulmonary exacerbation and were randomised during the 4.5-year study period. The time to next pulmonary exacerbation was not prolonged in the MCBT-treated group (hazard ratio 0.86 in favour of the conventionally-treated group, 95% CI 0.60-1.23, p=0.40). There was no difference between the groups in treatment failure rate. After 14 days of intravenous antibiotic therapy, changes in lung function, dyspnoea, and sputum bacterial density were similar in both groups. INTERPRETATION: Antibiotic therapy directed by combination antibiotic susceptibility testing did not result in better clinical and bacteriological outcomes compared with therapy directed by standard culture and sensitivity techniques. The non-bactericidal effects of antibiotic therapy might play an important part in determining improvement in patients with cystic fibrosis pulmonary exacerbations.

Recombinant activated factor VII for massive hemoptysis in patients with cystic fibrosis.

Massive hemoptysis is a common complication in patients with cystic fibrosis (CF) and is associated with significant morbidity and mortality. Conventional treatment with antibiotic therapy and early bronchial artery embolization (BAE) is usually successful in achieving hemostasis in the majority of patients. Recombinant activated factor VII (rFVIIa), originally developed for use in patients with hemophilia, has emerged as a general hemostatic agent that is potentially useful in the management of many life-threatening bleeding conditions. In this article, we present four patients with CF lung disease and massive hemoptysis who were treated successfully with rFVIIa. We suggest that in patients with CF who present with massive hemoptysis, the use of rFVIIa can be considered in patients with refractory hemoptysis despite conventional therapy or as a temporizing therapy when BAE is not immediately available.
