Clinicians' delirium treatment practice, practice change, and influences: A national online survey.

BACKGROUND: Recent studies cast doubt on the net effect of antipsychotics for delirium. AIM: To investigate the influence of these studies and other factors on clinicians' delirium treatment practice and practice change in palliative care and other specialties using the Theoretical Domains Framework. DESIGN: Australia-wide online survey of relevant clinicians. SETTING/PARTICIPANTS: Registered nurses (72%), doctors (16%), nurse practitioners (6%) and pharmacists (5%) who cared for patients with delirium in diverse settings, recruited through health professionals' organisations. RESULTS: Most of the sample (n = 475): worked in geriatrics/aged (31%) or palliative care (30%); in hospitals (64%); and saw a new patient with delirium at least weekly (61%). More (59%) reported delirium practice change since 2016, mostly by increased non-pharmacological interventions (53%). Fifty-five percent reported current antipsychotic use for delirium, primarily for patient distress (79%) and unsafe behaviour (67%). Common Theoretical Domains Framework categories of influences on respondents' delirium practice were: emotion (54%); knowledge (53%) and physical (43%) and social (21%) opportunities. Palliative care respondents more often reported: awareness of any named key study of antipsychotics for delirium (73% vs 39%, p < 0.001); changed delirium treatment (73% vs 53%, p = 0.017); decreased pharmacological interventions (60% vs 15%, p < 0.001); off-label medication use (86% vs 51%, p < 0.001: antipsychotics 79% vs 44%, p < 0.001; benzodiazepines 61% vs 26%, p < 0.001) and emotion as an influence (82% vs 39%, p < 0.001). CONCLUSION: Clinicians' use of antipsychotic during delirium remains common and is primarily motivated by distress and safety concerns for the patient and others nearby. Supporting clinicians to achieve evidence-based delirium practice requires further work.

Activities Forgone because of Chronic Breathlessness: A Cross-Sectional Population Prevalence Study.

Background: Chronic breathlessness is a prevalent disabling syndrome affecting many people for years. Identifying the impact of chronic breathlessness on people's activities in the general population is pivotal for designing symptom management strategies. Objective: This study aimed to evaluate the association between chronic breathlessness and activities respondents identify can no longer be undertaken ("activities forgone"). Design: This population-based cross-sectional online survey used a market research company's database of 30,000 registrants for each sex, generating the planned sample size-3000 adults reflecting Australia's 2016 Census by sex, age group, state of residence, and rurality. Setting/Subjects: The population of focus (n = 583) reported a modified Medical Research Council (mMRC) breathlessness scale ≥1 and experienced this breathlessness for ≥3 months. Measurements: Activities forgone were categorized by mMRC using coding derived from the Dyspnea Management Questionnaire domains. Activities were classified as "higher/lower intensity" using Human Energy Expenditure scale. Results: Respondents were male 50.3%; median age 50.0 (IQR 29.0); with 66% living in metropolitan areas; reporting 1749 activities forgone. For people with mMRC 1 (n = 533), 35% had not given up any activity, decreasing to 9% for mMRC 2 (n = 38) and 3% for mMRC 3-4 (n = 12). Intense sport (e.g., jogging and bike riding) was the top activity forgone: 42% (mMRC 1), 32% (mMRC 2), and 36% (mMRC 3-4). For respondents with mMRC 3-4, the next most prevalent activities forgone were "sexual activities" (14%), "lower intensity sports" (11%), and "other activities" (11%). Conclusions: People progressively reduce a wide range of activities because of their chronic breathlessness.
