In Singapore, an ageing population with increasing chronic disease burden and complex social circumstances have strained the healthcare system. For the health system to run more efficiently, patients should be appropriately sited according to their medical needs. In Singapore, community hospitals serve as an intermediate inpatient facility managing patients with sub-acute and rehabilitation care needs.

Introduction: Multiple Cochrane Reviews have demonstrated 'hospital at home' (HaH) as a promising healthcare model to be explored, with benefits such as higher care quality, reduced readmissions, shorter lengths of stay, lower cost and greater patient satisfaction. While there have been many reviews focusing on the quantitative clinical outcomes of HaH, there is generally a lack of collation of qualitative insights from stakeholders and lessons learnt from past HaH implementation.

Methods: We performed a systematic literature search on four databases and included 17 papers involving the provision of acute and/or subacute care by healthcare professionals in patients' homes.

Background: Medical training through specialization and even subspecialization has contributed significantly to clinical excellence in treating single acute conditions. However, the needs of complex patients go beyond single diseases, and there is a need to identify a group of generalists who are able to deliver cost-effective, holistic care to patients with multiple comorbidities and multi-faceted needs. Community hospitals (CHs) are a critical part of Singapore's shift toward a community-centric care model as the population ages.

Introduction: With the increasing complexity of healthcare problems worldwide, the demand for better-coordinated care delivery is on the rise. However, current hospital-based practices remain largely disease-centric and specialist-driven, resulting in fragmented care. This study aimed to evaluate the effectiveness and feasibility of an integrated general hospital (IGH) inpatient care model.

Objective: Hospital at Home (HaH) programs have been shown to improve quality of care and patient satisfaction, and reduce bed occupancy rate in hospitals. Despite the prevalence of HaH in Western countries, studies in Asia are limited and the perception of HaH remains underexplored in Asian context. Understanding the perceptions of stakeholders is vital before implementing HaH in any new settings.

Hospital-at-Home (HaH) programmes are well-established in Australia, Europe, and the United States. However, there is limited experience in Asia, where the hospital is traditionally seen as a safe and trusted space for healing. This cross-sectional study aimed to explore attitudes and perceptions among patients and caregivers in Singapore toward this care model.

Background: Hospital-at-home (HaH) provides acute healthcare in patients' homes as an alternative to traditional hospital inpatient care. HaH has been shown to improve clinical outcomes, increase patient satisfaction, and reduce hospitalization costs. Despite its effectiveness, the uptake of HaH remains slow and little is known about factors that impact the quality and transferability of HaH.

Smart Nation is a key initiative of Singapore to move toward digitalization of its industries including healthcare. The complex negotiations of aging amid Smart Nation are addressed in this paper, where we study the challenges faced to adapt the elderly for the digital revolution while ensuring dignified aging. While the healthcare industry accelerates its study and use of health technologies to improve diagnostics, treatment, and the quality of life of those in the aging category, the elderly socially construct these technological insertions that challenge the dominant understandings of what these technologies can do for their health outcomes.

Objectives: To provide an overview of the safety and effectiveness of Hospital-at-Home (HaH) according to programme type (early-supported discharge (ESD) vs admission avoidance (AA)), and identify the model with higher evidence for addressing clinical, length of stay (LOS) and cost outcomes.

Methods: A systematic review of reviews was conducted by performing a search on PubMed, EMBASE, Cochrane Database of Systematic Reviews, Web of Science and Scopus (January 2005 to June 2020) for English-language systematic reviews evaluating HaH. Data on primary outcomes (mortality, readmissions, costs, LOS), secondary outcomes (patient/caregiver outcomes) and process indicators were extracted.

Introduction: Hospital-based practices today remain predominantly disease-oriented, focusing on individual clinical specialties with less visibility on a comprehensive picture of each patient's health needs. To tackle the challenge of growing multimorbidity worldwide, practices without disease-specific focus have shown better integration of services. However, as we move away from the familiar disease-specific approaches of care delivery, many of us are still learning how to implement generalist care in a cost-effective manner.

Background: Over the past decades, the pharmacist's role has changed from being 'compounders and dispensers' to one of 'medication therapy manager' providing pharmaceutical care (PC). The transformation of pharmacy practice and its benefits, however, seem to be poorly understood by patients and caregivers (consumers) even in advanced health systems.

Objective: This study aims to assess the comprehension of consumers in Singapore towards PC and expectations on the scope of pharmacy services today.

Background: Integrated care has been well-recognized as a solution to improve quality of care for patients with complex needs. As Singapore increasingly develops and promotes integrated models of care, it is unclear if providers, patients, and caregivers share similar understanding of changes in the healthcare system.

Objectives: This study aims at exploring three dimensions of care integration: a) understanding of integration; b) challenges and c) changes perceived as essential among three distinct stakeholder groups: providers, patients and caregivers.

Introduction: Elderly patients intrinsically have higher bleeding risks, deterring clinicians from prescribing them oral anticoagulants. Setting a narrow international normalized ratio (INR) target range might potentially mitigate some of these risks. This study sought to compare the outcomes of elderly patients who were assigned to either a narrow INR target range or the conventional INR target range in a real-world environment.
