Co se týče ambulantního ošetření, zavolejte asistenční službě.

Co se týče is a very common Czech expression meaning as for, regarding, when it comes to, or as far as ... is concerned.

So:

• Co se týče ambulantního ošetření = As for outpatient treatment / Regarding outpatient treatment

It is best learned as a set phrase. A very literal word-for-word breakdown would not sound natural in English.

Because co se týče is followed by the genitive case.

So:

• ambulantní ošetření = outpatient treatment (basic dictionary form)
• co se týče ambulantního ošetření = regarding outpatient treatment (genitive form)

The changes are:

• ambulantní → ambulantního
• ošetření stays ošetření in form, but here it is functioning as genitive singular

This is a pattern worth remembering:

• co se týče + genitive

For example:

• Co se týče ceny... = As for the price...
• Co se týče pojištění... = Regarding insurance...

Ambulantní means outpatient or ambulatory, not ambulance in the English sense.

So ambulantní ošetření means treatment where the patient is not admitted to the hospital.

This can confuse English speakers because:

• English ambulance = emergency vehicle
• Czech ambulantní = outpatient / non-hospitalized care

So here the sentence is talking about outpatient medical treatment, not transport by ambulance.

Ošetření means treatment, medical care, or medical attention.

In this sentence, ambulantní ošetření is best understood as:

• outpatient treatment
• outpatient medical care

The noun ošetření comes from the verb ošetřit, which means to treat, to provide care, or sometimes to attend to.

Zavolejte is the imperative form of zavolat, meaning call!

More specifically, it is the:

• plural imperative, or
• formal singular imperative

So it can mean:

• Call! when speaking politely to one person
• Call! when speaking to more than one person

This is why it is appropriate in instructions, notices, customer service language, and formal advice.

Compare:

• zavolej = call! (informal, one person)
• zavolejte = call! (formal one person / plural)

This is a question of aspect, which is very important in Czech.

• volat = imperfective
• zavolat = perfective

In this context:

• volat focuses more on the process or repeated action of calling
• zavolat focuses on making a completed call

So zavolejte is the natural choice for an instruction like call the assistance service because it means something like:

• make the call
• give them a call
• call them

If the sentence used volejte, it would sound more like be calling / keep calling / call repeatedly, depending on context.

Because in Czech, volat / zavolat meaning to call someone on the phone normally takes the dative case.

So:

• zavolat komu? = to call whom?
• služba → službě in the dative singular

That is why the sentence says:

• zavolejte asistenční službě

not:

• zavolejte asistenční službu

For English speakers, this can feel strange because English uses a direct object:

• call the assistance service

But Czech commonly uses the dative with this verb:

• zavolat někomu = to call someone

Examples:

• Zavolám lékaři. = I’ll call the doctor.
• Zavolejte pojišťovně. = Call the insurance company.

Asistenční služba means assistance service or assistance line.

In a medical or insurance context, it usually refers to a support service you should contact for help, instructions, authorization, or coordination.

Depending on the situation, it could mean something like:

• the insurance assistance hotline
• a travel assistance service
• a medical assistance center

So zavolejte asistenční službě means call the assistance service / assistance hotline.

The comma separates the introductory phrase from the main instruction.

• Co se týče ambulantního ošetření, = introductory topic phrase
• zavolejte asistenční službě. = main clause

This is similar to English punctuation in sentences like:

• As for outpatient treatment, call the assistance service.
• Regarding outpatient treatment, please call the assistance service.

So the comma helps show that the first part sets the topic, and the second part gives the instruction.

The given word order is natural and clear:

• Co se týče ambulantního ošetření, zavolejte asistenční službě.

Czech word order is flexible, but this version sounds like standard written instruction. It starts with the topic, then gives the action.

You could rearrange parts in other contexts, but the original sentence is probably the best choice for neutral, formal communication.

Not very literal. A word-for-word translation would sound awkward.

A natural English translation would be:

• As for outpatient treatment, call the assistance service.
• Regarding outpatient treatment, please call the assistance service.
• For outpatient treatment, call the assistance service.

So when learning from this sentence, it is better to focus on:

• co se týče = regarding / as for
• zavolat komu = to call someone
• ambulantní ošetření = outpatient treatment

rather than trying to match every Czech word directly to an English one.
