While continuity of care is typically considered a principle of good medicine, its measurable health benefits are increasingly supported by clinical evidence.

Studies across multiple healthcare systems show that physician continuity is consistently associated with better outcomes, lower utilisation and, in some cases, reduced mortality.

For maritime operators managing complex, distributed workforces, there is a compelling case for maintaining consistent healthcare personnel.

Fewer hospitalizations and lower mortality

A 2024 retrospective study in Alberta, Canada, found that high continuity with a specific family physician was associated with fewer emergency department visits across all patient complexity levels, as well as fewer hospitalisations among highly complex patients.

In fact, the protective effect of continuity appeared to strengthen as medical complexity increased.

A 2020 review in the British Journal of General Practice analysed 13 studies and found that nine demonstrated protective effects against all-cause mortality where continuity was higher. Several also showed reduced deaths from coronary heart disease.

A separate review of 19 clinical studies published in 2024 in BMC Primary Care found that patient-reported continuity was linked to improved quality of life, better self-reported health, lower mortality and reduced hospital and emergency department use.

More recently, a 2025 systematic review in the British Journal of General Practice covering 18 studies and 5.6 million participants concluded with moderate certainty that higher personal continuity with a GP is likely to reduce both hospital admissions and emergency department visits.

While evidence based on administrative measures of continuity remains stronger, the direction of effect is consistent. Taken together, the pattern is difficult to ignore:

• Emergency department visits decrease with high physician continuity
• Hospitalisations decrease, particularly among highly complex patients
• All-cause mortality decreases across multiple systematic reviews
• Quality of life and self-rated health improve with stronger perceived continuity
• Overall healthcare utilisation reduces as continuity strengthens

Why does continuity change outcomes?

Continuity is not simply relational. It is clinical. When a physician follows an individual over time, they develop deep informational knowledge: medical history, behavioural patterns, typical responses to treatment and baseline health markers.

This contextual understanding allows subtle deviations to be identified earlier. Because the clinician knows what is and is not normal for that individual, they are more likely to:

• Detect small but meaningful changes
• Recognise early signs of deterioration
• Identify patterns that signal emerging risk

Earlier detection across conditions reduces complications and supports more timely intervention. Continuity also strengthens trust and communication. Patients who feel known are more likely to disclose concerns, adhere to care plans and seek support earlier. This reduces fragmentation and the risk of avoidable error.

In a high-stress field such as maritime, these factors carry additional weight. Seafarers work in isolated conditions where delayed recognition of physical or psychological decline can escalate quickly. Familiarity and trust therefore act as critical safeguards for human health at sea.

Continuity at sea – the operational relevance

Maritime healthcare systems often prioritise 24/7 availability. While critical, availability alone does not create continuity. Rotating clinicians who are unfamiliar with a vessel or its crew cannot build cumulative knowledge over time.

This is where structured continuity becomes an operational advantage.

OneHealth by VIKAND introduces a defined continuity framework through regular, scheduled engagement between Vessel Command and a designated senior maritime clinician – the ‘House Doctor’ – assigned to that specific vessel.

On a scheduled basis, typically monthly, the Vessel Command meets with the clincian to review crew health and environmental factors in a structured, data-led discussion.

This conversation covers:

• Physical or mental health concerns regarding specific crew members
• Vessel-wide health and wellness patterns
• Injury and illness trends
• Environmental factors that may affect wellbeing
• Evidence-based, practical wellness measures suited to that vessel
• Medical chest dispensing patterns and procurement needs
• Equipment training requirements
• Confirmation of key vessel-specific safety information

This regular cadence builds familiarity as the "House Doctor" gains insight into the vessel’s operational rhythm, crew composition and recurring risk patterns. Similarly, Vessel Command develops confidence in a clinician who understands their environment and crew members grow to trust and be known by their doctor.

The same principle applies within VIKAND Connect. Crew members and officers can schedule calls with assigned clinicians linked to their vessel. This differs materially from telemedicine models that rely solely on unscheduled, anonymous calls.

Scheduled consultations with assigned clinicians enable personal continuity. Over time, the clinician understands the individual’s baseline health, previous concerns and contextual stressors. VIKAND clinicians also have direct maritime experience, which strengthens communication and shared understanding without requiring explanation of shipboard realities.

A matter of performance

A substantial body of observational, cohort and retrospective research now demonstrates that when physicians know their patients, outcomes improve. Hospital visits are reduced, mortality decreases and patient wellbeing improves.

When care is consistent, insight deepens and risks are detected earlier. In maritime operations, this kind of continuity reduces disruptions, supports operational resilience and protects crew confidence at every level.
