Dr Jeremy Lim’s commentary presents a thoughtful and realistic discussion on Singapore’s new “principal doctor” (PD) model — a plan to have one doctor take overall responsibility for a hospital patient’s care. His article highlights the growing need for coordinated healthcare as Singapore’s population ages and more patients live with multiple chronic illnesses.
Today, many patients see several specialists who each focus on one organ or condition. This often leads to confusion, overlapping treatments, and fragmented care. The PD model aims to fix this by giving one hospital clinician the job of integrating input from different specialists so that every patient has a single, clear care plan.
Dr Lim agrees that the idea is sound but points out that implementation will be difficult. He identifies three major challenges:
- Professional boundaries: Different specialists may disagree on who is responsible for what, leading to turf conflicts.
- Pay and career incentives: Broad-based doctors who take on this coordinating role must be fairly compensated and respected, or few will want the job.
- Public perception: Patients may still equate “specialist” with “best,” and may not trust a generalist clinician to lead their hospital care.
He also notes important legal questions — such as who is liable if treatment decisions made by the PD go wrong — and stresses that clear policies will be needed to define accountability.
The commentary recommends learning from Singapore’s earlier success in strengthening family medicine under the Healthier SG initiative. Over time, public trust was built through better training, funding, and clear communication about family doctors’ roles. The same long-term commitment will be required to establish the PD as a respected hospital leader.
Ultimately, Dr Lim concludes that this reform is necessary. With more elderly and medically complex patients, hospitals must move from fragmented specialist care to integrated team care. Success will depend on clear authority for the PD, proper legal and payment frameworks, and a shift in both doctor and patient mindsets. If implemented well, the model can shorten hospital stays, prevent medication errors, and provide patients with safer, more coherent treatment.
