Sharps injury in the office: what to do

A needlestick is the kind of event that feels far away until it happens, in the middle of a visit, with the patient still on the table. What you do in the first minutes and first hours weighs the most on the outcome. This page organizes the reasoning for the orofacial harmonization (HOF) practitioner: immediate care, risk assessment, prophylaxis, documentation and prevention. Clinical and medication decisions belong to the reference service and the licensed practitioner, according to the rules of their professional board and local health surveillance, in Brazil.

Why do sharps injuries matter in HOF?

In HOF, the practitioner handles fine needles and blades in a small field, with a conscious patient who moves and, at times, under time pressure. Filler and toxin needles are small gauge, which changes how much biological material is transferred in an injury, but does not remove the risk or the duty to act.

The moments of greatest exposure are well known:

1. Recapping a needle, which should be avoided whenever the design of the device allows.
2. Disposal, when the container is full, badly placed or far from the counter.
3. Changing a needle or syringe with the free hand close to the tip.
4. A sudden movement by the patient during injection.
5. Cleaning and reprocessing sharp instruments without adequate protection.

What to do in the first minutes

Immediate care is simple and should be written down, trained and visible on the office wall.

Irritating products, injecting substances into the wound or increasing the bleeding have no support as management. Avoid improvising.

How is the exposure risk assessed?

The assessment considers three components, always together:

The reference service uses this information to decide on serologies, vaccination and chemoprophylaxis. In a HOF office, the source patient is usually present at the time of the injury. That helps: explain the situation calmly, ask for consent to collect what is needed and protect confidentiality. Information about the patient's health is sensitive data and follows the LGPD (Brazil's data protection law) and professional confidentiality rules.

Data that helps decide

If the source patient has hepatitis B or C, HIV or another known condition, it shows up in the medical history and changes the urgency of management. That is why a well-completed history also protects the practitioner. See medical history in HOF and hepatitis B and C and biosafety in HOF.

Prophylaxis and follow-up

Post-exposure prophylaxis is indicated according to risk, and some measures work better when started early. This page does not prescribe regimens, but organizes what the office should know beforehand:

• Practitioner vaccination. Hepatitis B vaccination status checked and documented, with proof of response when recommended.
• Identified reference service. Name, address, hours and phone number of the place where the assessment is done, written down and accessible.
• A flow for after hours. Weekends and nights have accidents too.
• Serological follow-up for the period indicated by the service, even if the source patient tests negative, when so directed.

Documentation, reporting and paperwork

The injury is both a workplace and a health event, and should be documented with date, time, circumstances, the material involved, measures taken and referrals. Reporting to the competent body and the form of notification follow the applicable health and labor legislation, which varies by location and employment relationship. Confirm the flow with the reference service and with the health surveillance of your municipality.

In the patient's record, note only what is necessary for their care. The practitioner's injury report goes in its own document, with restricted access. A patient who agreed to the tests is entitled to the results.

If the injury involves a faulty product or device, also consider an adverse event report and keep the lot number (injectable traceability).

How to reduce the chance of it happening

Prevention is the only point where you can be truly effective. The actions with the best cost-benefit are organizational:

• Immediate disposal of the used needle in the rigid container, placed at hand height. See sharps disposal and PGRSS (Brazil's healthcare waste management plan).
• No two-handed recapping; when unavoidable, use a one-handed technique or a support device.
• An organized counter. A place for the right instrument in the right spot reduces improvised movement. See organizing the procedure counter.
• Stable, comfortable patient positioning, with head support. See positioning the patient on the table.
• Cannulas when the procedure allows, at the practitioner's discretion, bearing in mind that a cannula also requires a needle for the entry point.
• Regular training of the team, including cleaning staff and reception.
• Sterilization and reprocessing according to sterilizing reusable materials.
• Breaks and ergonomics to avoid fatigue, as in ergonomics for the HOF practitioner.

Where Harmy fits in

A sharps injury is not an app topic, but an organized routine helps reduce improvisation. In Harmy, a projection is built before any injection, on the screen, with planning by area. That lets you discuss the plan with the patient without rushing at the table, and start the procedure with decisions already made. The projection is an illustrative simulation, not a promise of results, and it does not replace clinical planning.
