Its population grew from 1.65 million to 5.45 million from 1960 to 2021. By 2030, 25% will be aged 65 or older. Meanwhile, the proportion of older adults with three or more chronic diseases nearly doubled from 2009 to 2017. While increasing workload and case complexity have challenged general practitioners (GPs) and catalysed primary care transformation, there is also a need to re-examine the role of hospital specialists.<\/p><p>Specialisation has advanced medical science since the 19th century.<sup>3<\/sup>\u00a0Grouping populations with similar diseases and organ involvement has allowed doctors to promote research and efficiently master domains. In its first 3 decades post-independence, Singapore\u2019s health policy and funding catered to the growth of specialist-led hospitals and national centres.<sup>4<\/sup>\u00a0Correspondingly, public attitudes increasingly swung towards specialist as opposed to generalist care.<\/p><p>However, overly disease-centric, hospital-based specialist care is no longer sufficient or sustainable.<sup>5<\/sup>\u00a0Patients with more than 1 comorbidity, who are increasingly the norm, are now referred from one specialist to another specialist, with several consequences including lack of clear clinical accountability, long referral wait time, care fragmentation and polypharmacy.<\/p><p>Greater inconvenience and higher bills are incurred by patients from more visits to specialist outpatient clinics. For the healthcare system, manpower and financial sustainability is challenged by the need for more specialists, and the associated supporting staff and clinical spaces.<\/p><p><strong>Will generalists be able to fill the gap?\u00a0<\/strong>Generalists are typically defined as physicians who provide care to patients as a whole unit irrespective of age, sex and illness; they include GPs, paediatricians and internists who largely practise in the community.<sup>6<\/sup> This article describes hospital-based specialist-generalists who are arbitrarily divided into 2 broad groups: (1) advanced internal medicine (AIM) physicians, geriatricians and family medicine physicians, who receive broad-based training; and (2) all other specialists with an internal medicine (IM) background, e.g. nephrologists, endocrinologists, etc. (Fig. 1).<\/p><p>Both groups are better able than other non-IM physicians to handle medical conditions beyond their own specialties because of their background training. All IM specialists in Singapore today are required to complete 3 years of IM junior residency before entering 2\u20133.5-year senior residency programmes. These senior residency programmes then mandate an additional 6 months of general medicine (GM) and geriatrics rotations.<\/p><p>Meanwhile, the 2-year AIM senior residency programme specifically provides further honing of IM competencies. While the specialist-generalist care concept may in the future apply to non-IM disciplines like surgery, this commentary is limited to IM and family medicine physicians in hospitals, for whom such a concept is more readily achievable.<\/p><\/div><p>At present, various care models exist in Singapore. Tertiary hospitals\u2019 inpatient and outpatient activities are primarily specialist rather than generalist-driven. Non-tertiary regional hospitals tend to admit more patients under GM, an umbrella term used for the care of patients not assigned to specific specialties. While GM is ideally covered by AIM, only 138 of Singapore\u2019s 15,430 medical practitioners were IM-accredited in 2020.<sup>7<\/sup> Thus, non-AIM medicine specialists also provide care in GM. Separately, outpatient care in most hospitals remains largely helmed by specialists who narrowly focus on their own expertise.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-717991b elementor-widget elementor-widget-heading\" data-id=\"717991b\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-xl\">Is Generalist or Specialist better?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-04300dc elementor-widget elementor-widget-text-editor\" data-id=\"04300dc\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>While comparison between generalists and specialists has been a subject of interest, there is a scarcity of literature on specialist-generalists, with most studies having evaluated primary care physicians as generalists. The validity of these studies is often questionable due to selection and publication biases. In a systematic review, 24 of 49 studies suggested better outcomes with specialists and only 4 studies suggested that generalist care was superior.<sup>8<\/sup>\u00a0The studies were mostly observational and involved discrete diseases. It is unsurprising that specialists fare better in their domain expertise, just as they may better master procedural skills and adhere to disease-specific guidelines.<\/p><p>In contrast, some studies have reported generalists outperforming specialists in managing certain conditions. One demonstrated lower resource use by older adults with diabetes who were managed by a primary care physician instead of a medical specialist.<sup>9<\/sup>\u00a0In a Singapore retrospective study, inpatients cared for by family physicians as generalists had shorter lengths of stay and lower costs than those cared for by specialists managing general medicine inpatients, with equivalent outcomes in hospital mortality and 30-day all-cause unscheduled readmissions.<sup>10<\/sup><\/p><p>Existing research has generally failed to evaluate indicators of quality of care for the patient\u2019s whole journey, across conditions and settings. While specialists tackle fewer new complaints and focus less on preventive care,<sup>11<\/sup>\u00a0generalists often see patients with undifferentiated problems on top of their existing conditions. Generalist physicians are trained to provide comprehensive care within the context of a patient\u2019s multimorbidity and psychosocial circumstances. Indeed, it is not always appropriate to follow guidelines upon which disease-specific quality indicators are based.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5b2d239 elementor-widget elementor-widget-heading\" data-id=\"5b2d239\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-xl\">Can Generalists Go Deeper?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d5c1c66 elementor-widget elementor-widget-text-editor\" data-id=\"d5c1c66\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Generalists may take a holistic, whole-person approach, but strengthening their ability to deal with specific diseases, systems and organs may lead to multiple benefits including increased cost-effectiveness, improved appropriateness of referrals to specialists, reduced reliance on tertiary care centres, and enhanced job satisfaction.<\/p><p>Examples of interventions to strengthen generalist care include greater adoption of guidelines that address multimorbidity as identified by symptom complexes and burdens, development of question lists to better manage clinical scenarios, and additional training in specific specialty areas. In the UK, GPs with special interests lead strategic planning through the primary care lens, for areas traditionally helmed by specialties. In the US, inpatient hospitalist care has become the norm. In Singapore, success in involving family medicine doctors in inpatient GM care has been achieved.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1472b82 elementor-widget elementor-widget-heading\" data-id=\"1472b82\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-xl\">Can Generalists Go Broader?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-21f6e53 elementor-widget elementor-widget-text-editor\" data-id=\"21f6e53\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Specialists may focus on their respective domain expertise, but greater ability to deal with their patients\u2019 other comorbidities will make care substantially more holistic. A Singapore study described a model of inpatient care where physicians including those from family medicine performed generalist duties. This model was associated with similar healthcare costs, shorter length of stay and lower mortality vis-\u00e0-vis a model in which specialists predominantly looked after their own specialties.<\/p><p>However, chronic care, which involves longer-term follow-up, may be more challenging. Specialists who manage most or all their patients\u2019 health concerns as principal physicians exist but are often confined to specific populations.<\/p><p>For example, in a survey of nephrologists, 75% led care beyond nephrology for their dialysis patients, including cancer screening, immunisation and comorbidity management. Practice guidelines for chronic kidney disease encourage managing physicians to provide holistic care in the form of glycaemic control, cardiovascular risk reduction, hyperuricaemia management and lifestyle modification.<\/p><p>While specialists may provide holistic care of common chronic conditions if empowered and incentivised, the tussle with diminished time left for specialty work as well as a lack of familiarity with the management of other comorbidities precludes this.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e2e4e29 elementor-widget elementor-widget-text-editor\" data-id=\"e2e4e29\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p style=\"text-align: left;\"><span style=\"font-family: arial, helvetica, sans-serif;\"><span style=\"font-weight: 400;\">Reference: <\/span><a href=\"https:\/\/www.hsa.gov.sg\/docs\/default-source\/hprg-vcb\/adverse-events\/mobile-ae-form.pdf\"><span style=\"font-weight: 400;\">Annals<\/span><\/a><\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e5ca179 elementor-widget elementor-widget-spacer\" data-id=\"e5ca179\" data-element_type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.21.0 - 24-04-2024 *\/\n.elementor-column .elementor-spacer-inner{height:var(--spacer-size)}.e-con{--container-widget-width:100%}.e-con-inner>.elementor-widget-spacer,.e-con>.elementor-widget-spacer{width:var(--container-widget-width,var(--spacer-size));--align-self:var(--container-widget-align-self,initial);--flex-shrink:0}.e-con-inner>.elementor-widget-spacer>.elementor-widget-container,.e-con>.elementor-widget-spacer>.elementor-widget-container{height:100%;width:100%}.e-con-inner>.elementor-widget-spacer>.elementor-widget-container>.elementor-spacer,.e-con>.elementor-widget-spacer>.elementor-widget-container>.elementor-spacer{height:100%}.e-con-inner>.elementor-widget-spacer>.elementor-widget-container>.elementor-spacer>.elementor-spacer-inner,.e-con>.elementor-widget-spacer>.elementor-widget-container>.elementor-spacer>.elementor-spacer-inner{height:var(--container-widget-height,var(--spacer-size))}.e-con-inner>.elementor-widget-spacer.elementor-widget-empty,.e-con>.elementor-widget-spacer.elementor-widget-empty{position:relative;min-height:22px;min-width:22px}.e-con-inner>.elementor-widget-spacer.elementor-widget-empty .elementor-widget-empty-icon,.e-con>.elementor-widget-spacer.elementor-widget-empty .elementor-widget-empty-icon{position:absolute;top:0;bottom:0;left:0;right:0;margin:auto;padding:0;width:22px;height:22px}<\/style>\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a44b9e1 elementor-widget elementor-widget-heading\" data-id=\"a44b9e1\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h4 class=\"elementor-heading-title elementor-size-large\">Related Articles<\/h4>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-262dc68 elementor-widget elementor-widget-text-editor\" data-id=\"262dc68\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><a href=\"https:\/\/www.medicare-asia.com\/what-is-the-difference-between-an-fp-doctor-and-a-gp-doctor\/\"><span style=\"font-family: arial, helvetica, sans-serif;\">FP and GP what is the difference?<\/span><\/a><\/p><p><a href=\"https:\/\/www.medicare-asia.com\/family-medicine-specialty-in-singapore\/\"><span style=\"font-family: arial, helvetica, sans-serif;\">Family Medicine Speciality in Singapore<\/span><\/a><\/p><p><span style=\"font-family: arial, helvetica, sans-serif;\"><a href=\"https:\/\/www.medicare-asia.com\/en\/guide-to-community-health-assist-scheme-chas-in-singapore\/\">Guide to the Community Health Assistant Scheme<\/a><a href=\"https:\/\/www.medicare-asia.com\/en\/how-to-onboard-healthier-sg-for-gp-clinics\/\"> Clinics<\/a><\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Increasing workload and case complexity of a multimorbid ageing population have catalysed primary care transformation for general practitioners to meet these challenges.
