Chronic Aspiration Pneumonitis Caused by Spontaneous Cerebrospinal Fluid Fistulae of the Skull Base.

OBJECTIVES/HYPOTHESIS: Spontaneous cerebrospinal fluid (CSF) leaks of the skull base are associated with obesity, multiparity, and elevated intracranial pressure. Although spontaneous CSF leaks often present with rhinorrhea, they can be an underdiagnosed cause of chronic aspiration pneumonitis, a complication that has not been previously reported in detail. STUDY DESIGN: Retrospective case series. METHODS: The authors retrospectively reviewed all patients undergoing surgical repair of CSF fistulae at the University of Southern California between 2011 and 2018 to identify those presenting with pulmonary symptoms including dyspnea, aspiration, chronic cough, and shortness of breath caused by chronic noniatrogenic CSF pneumonitis. RESULTS: Symptomatic chronic pneumonitis was evident in six of 20 patients with spontaneous CSF rhinorrhea. Five women (mean body mass index = 36) had CSF leaks arising from the fovea ethmoidalis (n = 4) and lateral sphenoid region (n = 1). One man had a middle fossa floor dehiscence draining through the eustachian tube. All patients had bilateral ground-glass opacities in their lungs on computed tomography imaging that were attributed to spontaneous CSF fistulae arising from noniatrogenic skull base defects, and one patient underwent a biopsy of a lung lesion at another hospital showing chronic bronchiolitis and adjacent peribronchiolar metaplasia. Five patients underwent endoscopic endonasal repair using an autologous fascial graft and pedicled nasoseptal flap, and one underwent craniotomy for repair. All patients underwent successful repair with no complications or evidence of recurrence. Upon repair of the spontaneous CSF leaks, both pneumonitis symptoms and ground-glass opacities on imaging resolved in all six cases. CONCLUSIONS: Skull base CSF fistulae should be considered as a reversible cause of chronic pneumonitis that is not alleviated or worsens with standard treatment.

Workforce, Workload, and Burnout in Critical Care Organizations: Survey Results and Research Agenda.

OBJECTIVES: This report provides analyses and perspective of a survey of critical care workforce, workload, and burnout among the intensivists and advanced practice providers of established U.S. and Canadian critical care organizations and provides a research agenda. DESIGN: A 97-item electronic survey questionnaire was distributed to the leaders of 27 qualifying organizations. SETTING: United States and Canada. PARTICIPANTS: Leaders of critical care organizations in the United States and Canada. INTERVENTIONS: None. DATA SYNTHESIS AND MAIN RESULTS: We received 23 responses (85%). The critical care organization survey recorded substantial variability of most organizational aspects that were not restricted by the critical care organization definition or regulatory mandates. The most common physician staffing model was a combination of full-time and part-time intensivists. Approximately 80% of critical care organizations had dedicated advanced practice providers that staffed some or all their ICUs. Full-time intensivists worked a median of 168 days (range 42-192 d) in the ICU (168 shifts = 24 7-d wk). The median shift duration was 12 hours (range, 7-14 hr), and the median number of consecutive shifts allowed was 7 hours (range 7-14 hr). More than half of critical care organizations reported having burnout prevention programs targeted to ICU physicians, advanced practice providers, and nurses. CONCLUSIONS: The variability of current approaches suggests that systematic comparative analyses could identify best organizational practices. The research agenda for the study of critical care organizations should include studies that provide insights regarding the effects of the integrative structure of critical care organizations on outcomes at the levels of our patients, our workforce, our work practices, and sustainability.

Workforce, Workload, and Burnout Among Intensivists and Advanced Practice Providers: A Narrative Review.

OBJECTIVES: To assess-by literature review and expert consensus-workforce, workload, and burnout considerations among intensivists and advanced practice providers. DESIGN: Data were synthesized from monthly expert consensus and literature review. SETTING: Workforce and Workload section workgroup of the Academic Leaders in Critical Care Medicine Task Force. MEASUREMENTS AND MAIN RESULTS: Multidisciplinary care teams led by intensivists are an essential component of critical care delivery. Advanced practice providers (nurse practitioners and physician assistants) are progressively being integrated into ICU practice models. The ever-increasing number of patients with complex, life-threatening diseases, concentration of ICU beds in few centralized hospitals, expansion of specialty ICU services, and desire for 24/7 availability have contributed to growing intensivist staffing concerns. Such staffing challenges may negatively impact practitioner wellness, team perception of care quality, time available for teaching, and length of stay when the patient to intensivist ratio is greater than or equal to 15. Enhanced team communication and reduction of practice variation are important factors for improved patient outcomes. A diverse workforce adds value and enrichment to the overall work environment. Formal succession planning for ICU leaders is crucial to the success of critical care organizations. Implementation of a continuous 24/7 ICU coverage care model in high-acuity, high-volume centers should be based on patient-centered outcomes. High levels of burnout syndrome are common among intensivists. Prospective analyses of interventions to decrease burnout within the ICU setting are limited. However, organizational interventions are felt to be more effective than those directed at individuals. CONCLUSIONS: Critical care workforce and staffing models are myriad and based on several factors including local culture and resources, ICU organization, and strategies to reduce burden on the ICU provider workforce. Prospective studies to assess and avoid the burnout syndrome among intensivists and advanced practice providers are needed.
