In-House vs Outsourced OHC: Which Is Right for Your Plant?

Once a factory accepts it needs an occupational health centre, the next decision is who runs it. Hire your own nurse and doctor and manage it in-house, or outsource the whole operation to a specialist occupational health provider? Both models work — for different plants. This article compares them honestly across the five dimensions that matter, and ends with a decision framework you can apply to your own site.

What each model actually means

In-house OHC: you recruit the nurse, engage the visiting doctor, buy the equipment and medicines, maintain the registers, and manage it all through your HR or EHS team. The OHC is your department.

Outsourced (managed) OHC: a provider supplies the staff, equipment, medicine replenishment, registers, audit and supervision as a monthly service. You pay a fee; they own the checklist. Our occupational health centre services are the managed model.

There is also a hybrid: your own nurse, with the doctor panel, statutory examinations and audit outsourced. More on that below.

Dimension 1: Compliance risk

This is where the models differ most. Statutory OHC compliance is a chain — staffing presence, valid qualifications, equipment against the prescribed list, unexpired medicines, current registers, timely examinations, correct certificate formats. Every link must hold every day.

In-house, every link is your responsibility. If your nurse resigns, cover lapses while you recruit. If nobody owns the expiry audit, medicines age out. If the visiting doctor's format is wrong, you find out at inspection. Companies with a strong EHS team that understands medical compliance manage this well; most factories discover the gaps at the worst moment.

Outsourced, the provider is contractually accountable for the chain — relief cover, replenishment audits, register discipline and inspection support are in the service scope. The risk does not disappear, but it moves to a party whose business is managing it.

Dimension 2: Cost

In-house looks cheaper on a spreadsheet: a nurse's salary plus a doctor's visit fee versus a provider's monthly invoice. The honest comparison adds what the spreadsheet misses: recruitment and attrition of medical staff, relief cover, medicine wastage, equipment maintenance and calibration, management time, and the cost of compliance failures.

For a large plant running three shifts with a full-time medical officer, in-house can genuinely be the economical model — the scale justifies the management layer. For a single-shift or mid-sized plant, the managed model usually wins on total cost once relief cover and supervision are priced in. The OHC cost breakdown article covers the components in detail.

Dimension 3: Quality of care

An OHC is also your workers' first point of medical contact — its quality shapes whether they trust and use it. In-house quality depends entirely on who you hired and how well they are supervised; a lone nurse with no clinical supervision plateaus quickly.

A specialist provider brings protocols, a doctor panel for escalation, trained relief staff, and experience across many plants — the nurse at your site is backed by an organisation that has seen your problem before. Ask any provider how their staff are supervised clinically; the answer tells you whether you are buying a person or a system.

Dimension 4: Control and culture fit

The case for in-house is control: the OHC team is your team, embedded in your plant's culture, attending your safety meetings, knowing your workers by name. Some large plants value this enough to pay the management premium.

Managed providers address this through dedicated staffing — the same nurse at your site every day, attending your toolbox talks — plus a service manager who owns the relationship. If control is your main reason for preferring in-house, test whether a dedicated-staffing managed model gives you the same floor presence without the management load.

Dimension 5: Scalability and multi-site consistency

If you operate several plants, the question multiplies. In-house means recruiting and managing medical staff in every location, with consistency depending on each local hire. A managed provider gives you one contract, one protocol, one register format and one dashboard across sites — which is why multi-plant companies disproportionately choose the managed model. Our doctor and nurse staffing service is built for exactly this.

The hybrid option

Many plants land in the middle: their own nurse (who may have been at the plant for years and knows everyone) with the provider supplying the AFIH visiting doctor, the statutory examination programme, medicine audits and register oversight. This keeps the trusted local presence while closing the compliance and supervision gaps. It is a legitimate model — just be explicit in the contract about who owns which link in the compliance chain.

A decision framework

Choose in-house if you run a large plant (roughly 1,000+ workers or continuous hazardous processes), have an EHS team that understands medical compliance, and want the OHC as an embedded department.

Choose outsourced if you are a mid-sized plant, run multiple sites, have had compliance findings before, or simply want one accountable party for the whole chain.

Choose hybrid if you have a trusted existing nurse but need the doctor panel, examinations and audit layer around her.

Whichever model you pick, audit it: walk the compliance chain — presence, qualifications, equipment, medicines, registers, examinations, certificates — and confirm every link has a named owner.

Frequently asked questions

Can we switch from in-house to outsourced without disrupting the OHC?

Yes. Providers typically absorb the existing nurse where she is suitable, take over replenishment and registers, and schedule the doctor panel — with a handover audit so nothing lapses in between.

Who employs the nurse in a managed model?

The provider employs and supervises the nurse, handles her leave cover and training, and is accountable for her presence and performance under the service agreement.

Is outsourcing allowed for statutory functions?

The statutory obligations sit with you as the occupier — outsourcing the operation does not outsource the responsibility. That is precisely why the provider's accountability, records and inspection support matter; the function can be delivered by a specialist while you remain demonstrably in control.

What should a managed OHC contract include?

Staffing plan with qualifications, shift cover and relief arrangement; equipment and medicine scope with replenishment and expiry audit; register and record responsibility; the statutory examination programme; reporting cadence; and inspection support.

We have three plants in different states. One contract?

Yes — that is the standard multi-site managed model, with state-specific rule mapping for each plant. Request a proposal with your site list.
