Failure,Dehydration,Hyperglycemia/Hypoglycemia,Hypertension,Infections,Sickle Cell Anemia,Pain Management,Observation medicine can improve health outcomes by providing:,early access to short-term specialist services (such as multidisciplinary, specialist advice and care) and experienced staff able to observe patients with diverse problems and address the complex needs of patients,intensive or short-term care/frequent evaluation (assessment, observation and/or therapy) of a specific group of ED patients to rapidly diagnose conditions and expedite care,evidence-based care pathways to facilitate assessment and treatment and reduce unnecessary variations in care delivery,Observation medicine can improve health outcomes by providing:,a coordinated interdisciplinary team approach with early specialist intervention and integration with broader hospital and community services,decreased length of stay and decreased multiday hospital admission rates without increasing the rate of hospitalisation or readmission,an environment more comfortable for patients than the ED,avoidance of inappropriate departure from an ED,greater continuity of care by reducing the number of transitions that can lead to errors, delay, duplication and lost information,Observation medicine can improve patient flow by:,providing a comprehensive care model specific for patients requiring short-term treatment or observation,streamlining the delivery of appropriate health services to ensure more timely care delivery and thus earlier discharge,reducing avoidable admissions (for exle older patients, chest pain),increasing capacity to manage high ED patient volume,actively seeking appropriate patients (pull) from the ED early in their episode of care,avoiding prolonged ED stays and/or the use of multiday inpatient beds for patients requiring less than 24-48 hours of care,Key principles for observation medicine,Patient centred,Quality and safety,Early access,Evidence-based care,Substitution,Collaboration,Efficiency,Patient centred carecare is respectful of, and responsive to, individual patient preferences, needs and values, and provided in a comfortable environment,Quality and safetysystems and processes deliver quality outcomes and minimise risks., Early accessthere is early access to diagnostics, specialist advice, observation and reassessment to inform rapid decision-making and treatment,Evidence-based carepathways and protocols are in place to guide the delivery of care and reduce variation,Substitutionobservation medicine units are used as an alternative to traditional ED and inpatient models of care for patients requiring an extension of ED services,Collaborationobservation medicine units are managed in a way that improves links within the organisation (for exle, between multidisciplinary clinicians and specialists) and with external stakeholders (for exle, general practitioner and community service providers),Efficiencyobservation medicine units contribute to efficient use of resources by streamlining the care of selected patients and reducing service duplication and avoidable use of inpatient resources.,
