Pulmonary Hypertension (PH) is a life-shortening condition characterised by episodes of decompensation precipitated by factors such as disease progression, arrhythmias and sepsis. Surgery and pregnancy also place additional strain on the right ventricle. Data on critical care management in patients with pre-existing PH are scarce.We conducted a retrospective observational study of a large cohort of patients admitted to the critical care unit of a national referral centre between 2000–17 to establish acute mortality, evaluate predictors of in-hospital mortality and establish longer-term outcomes in survivors to hospital discharge.242 critical care admissions involving 206 patients were identified. Hospital survival was 59.3%, 94% and 92% for patients admitted for medical, surgical or obstetric reasons. Medical patients had more severe physiological and laboratory perturbations than patients admitted following surgical or obstetric interventions. Higher APACHE II score, age and lactate, and lower SpO2/FiO2, platelet count and sodium level were identified as independent predictors of hospital mortality. An exploratory risk score, OPALS (Oxygen (SpO2:FiO2), ≤185; Platelets, ≤196×109·L−1; Age, ≥37.5 years; Lactate, ≥2.45 mmol·L−1; Sodium, ≤130.5 mmol·L−1), identified medical patients at increasing risk of hospital mortality. One of nine patients (11%) who were invasively ventilated for medical decompensation and 50% of patients receiving renal replacement therapy left hospital alive. There was no significant difference in exercise capacity or functional class between follow-up and pre-admission in patients who survived to discharge.These data have clinical utility in guiding critical care management of patients with known PH. The exploratory OPALS score requires validation.

Background Discontinuing what is considered the most effective treatment for treatment-resistant schizophrenia may precipitate feelings of failure or a relapse of illness. Clozapine treatment is discontinued for a variety of reasons, including non-adherence, intolerance, or lack of efficacy. Patients’ experiences of discontinuing the “best” treatment and the impact on perceptions of subsequent antipsychotic treatment are important in developing an understanding of the factors affecting people’s treatment choices. This study is the first of its type, seeking to explore people’s perspectives on clozapine discontinuation. Method Semi-structured interviews with sixteen patients who had received clozapine and discontinued treatment—thirteen males and three females, age range: thirty-two to seventy-eight years old—were audio-recorded and transcribed. A modified inductive approach to analysis, based on grounded theory, was taken to identify commonalities and differences in patients’ perceptions. Results The three main themes identified from participants’ experiences were: positive and negative effects of treatment; feelings of agency, being the capacity to make decisions about treatment and act independently; choice of treatment in the future. Participants exhibited agency in making choices about medication, including risking relapse, while attempting self-management of medication effects. Different participants perceived the same side effect as beneficial or intolerable. Variation in subsequent treatment choices was reported, with some participants favouring depot (long-acting) injections. A participant was frightened when not told about clozapine’s side effects, which led to the participant not being engaged in future treatment decisions. Others, despite suffering serious adverse effects, retained positive perceptions of clozapine; they experienced despair at finding an effective alternative. Conclusions Experiences with clozapine discontinuation evoked powerful emotions and resulted in clozapine being the benchmark for other treatments. Knowledge, agency, and being in control were important to participants in relation to treatment. Personal perceptions of treatments or beliefs about illness could lead to non-adherence. People value the clinician listening to their experiences to better understand their perspective, enabling concerns about medication to be addressed through true shared decision making.

Medical patients had more severe physiological and laboratory perturbations than patients admitted following surgical or obstetric interventions. Higher APACHE II (Acute Physiology and Chronic Health Evaluation) score, age and lactate, and lower oxygen saturation measure by pulse oximetry/inspiratory oxygen fraction (S pO 2 /F iO 2 ) ratio, platelet count and sodium level were identified as independent predictors of hospital mortality. An exploratory risk score, OPALS (oxygen (S pO 2 /F iO 2 ) ⩽185; platelets ⩽196×10 9 •L −1 ; age ⩾37.5 years; lactate ⩾2.45 mmol•L −1 ; sodium ⩽130.5 mmol•L −1 ), identified medical patients at increasing risk of hospital mortality. One (11%) out of nine patients who were invasively ventilated for medical decompensation and 50% of patients receiving renal replacement therapy left hospital alive. There was no significant difference in exercise capacity or functional class between follow-up and pre-admission in patients who survived to discharge.These data have clinical utility in guiding critical care management of patients with known PH.

Nevertheless, many show longer term survival and functional recovery. Markers of severity of acute illness at admission are prognostic. https://bit.ly/2YX9Fw9
