Introduction: Platypnoea-orthodeoxia syndrome (POS) is an uncommon clinical entity characterised by dyspnoea and platypnoea (oxygen desaturation that follows the assumption of an upright position from recumbency). Since the coronavirus disease 2019 (COVID-19) outbreak, increasing reports of COVID-19-related POS and its associated morbidity have been reported around the world. We aimed to study the characteristics of COVID-19-related POS and orthodeoxia (including associations leading to a more prolonged orthodeoxia), and the postdischarge functional outcomes of patients with COVID-19-related POS.
Methods: An observational cohort study was conducted in a tertiary hospital that managed post-COVID-19 patients. Twenty-four participants with severe-to-critical COVID-19 disease/pneumonia and POS, who received inpatient pulmonary rehabilitation, were enrolled. Descriptive analysis of the data was performed to describe POS/orthodeoxia characteristics and functional outcomes in these participants. Correlation analyses were carried out to identify significant factors associated with a prolonged orthodeoxia.
Results: The mean duration of POS and orthodeoxia was 12.9 ± 8.3 days and 28.5 ± 14.6 days, respectively. All participants demonstrated resolution of POS and orthodeoxia by hospital discharge. On multivariable analysis, intensive care unit admission and maximal level of respiratory support were significantly associated with a prolonged duration of orthodeoxia. One participant was lost to follow-up. The remaining 23 participants achieved independence in self-care. With the exception of one patient, who was recovering from a hip fracture, the rest achieved independence in ambulation and independent community access.
Conclusion: Resolution of orthodeoxia was observed in all our participants with COVID-19-related POS. Good functional outcome can be attained with timely and effective rehabilitation interventions.

Introduction: Inhaler therapy is paramount in asthma management, yet non-adherence poses a significant challenge. This study investigates inhaler adherence patterns among adult asthma patients, employing the Test of Adherence to Inhalers (TAIs) questionnaire.
Methods: This cross-sectional study recruited 99 eligible patients from a specialist outpatient clinic over six months. The TAI questionnaire was administered to the patients. Data on asthma control test scores, medication possession ratio, and healthcare utilisation were collected. Statistical analyses were performed to examine the associations between adherence, patient characteristics, and clinical outcomes.
Results: More than half of the patients (68.7%) exhibited intermediate ( n = 23) or poor ( n = 45) adherence, with younger age associated with poorer adherence. Different patterns of non-compliance were identified; 38.8% ( n = 19) of patients with poor adherence showed deliberate non-compliance, whereas only 7.3% ( n = 3) with good adherence showed unconscious non-compliance. Surprisingly, patients with intermediate and poor adherence often achieved good asthma control, revealing potential challenges in outcome-based adherence assessments. A relatively higher but statistically non-significant proportion of patients with poor adherence had at least one hospitalisation or emergency department attendance due to asthma (42.2% with poor adherence vs. 35.5% with good adherence) or at least one asthma exacerbation requiring oral corticosteroid (64.4% with poor adherence vs. 48.4% with good adherence) in the past 12 months.
Conclusion: This study provides insights into inhaler adherence among local adult asthma patients, identifying distinct adherence patterns and recognising potential complacency issues associated with traditional adherence assessments. Despite these limitations, our findings contribute to the optimisation of asthma care through a nuanced understanding of inhaler adherence.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has caused significant mental distress in populations globally. At the frontline of the pandemic, emergency departments (EDs) are the prime setting to observe the effects of the pandemic on the mental health of the population. We aimed to describe the trend of mental health-related ED attendances at an acute hospital in Singapore before and during the various stages of the COVID-19 pandemic.
Methods: This is a retrospective, descriptive study of patients who presented to the ED between 1 January 2019 and 31 December 2020. Patients diagnosed with mental health-related systematised nomenclature of medicine who visited the ED during this period were identified and were placed into mental health diagnosis categories for analysis. A comparison was made between patients who presented before the pandemic (2019) and during the pandemic (2020).
Results: During the study periods, we identified 1,421 patients, of whom 27 were excluded due to non-mental health-related diagnoses, leaving 1,394 patients for analysis. There was a 36.7% increase in mental health-related ED presentations from 2019 to 2020. The proportion of higher-acuity mental health-related ED attendances and number of suicide attempts also increased.
Conclusion: Our study described an increase in the proportion of high-acuity mental health-related ED attendances during the COVID-19 pandemic. Emergency physicians must be cognisant of the effects of the pandemic on mental health. Further research should be conducted to better equip the healthcare system for handling all aspects of the pandemic.
