Clinical & episodes of care

Clinical care software: Clinical work, recorded properly — with your clinicians making every call.

Community nursing and wound care run on episodes, not open-ended rosters: a referral arrives, a funded piece of work opens, visits happen, dressings get used, and somebody has to bill the right payer at the price that applied on the day. Corella models that shape directly, and keeps the record while your clinicians do the interpreting.

How it flows

Referral in, episode open, the right payer billed.

1Referral
A person triages the referral and accepts it. The office opens an episode of care for the patient, naming the payer, the approval and the referrer.
2Episode
The episode carries the visits booked against it, the consumables recorded against it and its invoices for that funded piece of work, with its funding in dollars, visits or hours. A note written on one of its visits joins it, and wounds, documents and letters can be filed on it.
3Visit
The nurse clocks on, fills the practice's visit form and writes the note, which joins the visit's episode. Every measurement is typed by the nurse.
4Record
Corella works out area, volume and the change against that wound's first measurement. The note locks when it's final; a correction is an addendum.
5Bill
Visits and dressings price from the payer's card in force on each service date, bill once, and group into invoices by patient, funding and episode.

What people ask first

The short answers, up front.

What is an episode of care?
A named, dated piece of funded work for one patient. It carries the visits booked on it, the consumables recorded against it and its invoices, and names who pays. A note written on one of its visits joins it, and wounds, documents and letters can be filed on it.
Who can be a payer?
An insurer, a plan manager, a residential aged-care facility or home-care provider, a hospital, a GP practice, community health, a government funder such as DVA, TAC, WorkCover or state health, an employer, or the patient.
Which price does a visit get?
The one on the payer's rate card in force on the service date, whenever the invoice is raised.
What does the wound chart show?
Arithmetic on the numbers your nurse typed, labelled on every trend, chart and comparison: “A record of what was measured. Not a clinical assessment.” Your clinician reads it and decides.
Where does the next review date show?
On the wound record: the next review date your clinician sets on the wound's treatment plan.
What happens once a note locks?
It stays exactly as written, for its author and administrators alike. A correction is an addendum with its own reason, and the original stays visible.
How are dressings billed?
At the payer's price, exactly once. An invoice run takes only unbilled use, and voiding the invoice releases it for the next run.
Can we say patient instead of client?
Yes. Choose patient, nurse and episode of care, and the interface follows your words.
Can DVA be a payer?
Yes. DVA can be a payer with its own rate card, and Corella raises the invoice to it.
How is AI switched on?
Feature by feature: each AI feature has its own switch, separate from any preset. Where one is on, text is processed by our AI provider in the United States under terms that prohibit training on customer content, and speech is transcribed in the European Union, with your instance instructing that service, once the text comes back, to delete the recording and its copy of the text.

Whose screen

The same job, from each seat.

A nurse showing an older man something on a tablet

In the office

The front desk books each visit against the right episode, and the booking drawer warns before saving if the visit would take the episode's funding or the payer's contract near or over its limit — in dollars, visits or hours — and names the episode's state if it's on hold, closed or expired. The clinical lead keeps the wound record: the measurements, the trend, the date-range comparison, the CSV export and the photographs, which stay on office screens. Finance keeps the payers, their dated rate cards and contracts, and runs the invoices.

On the phone

The nurse's phone shows today's visits as a timeline with the free time between them labelled, and the need-to-know brief at clock-on when anything is recorded. At the visit they fill the practice's visit form — the wound-care template works out area from length × width, and with copy-forward switched on it starts from the last visit's answers, each marked “Unchanged from the previous visit” — write the note, which joins the visit's episode, and record the observation charts your office keeps for that patient. It's a web app installed from the browser.

A worked example

One episode, two rate cards, one invoice

An insurer-funded leg ulcer episode, with a nursing visit either side of the insurer's new schedule on 1 July and a dressing used at each. Demo figures — not a real payer's prices.

Visit on Tuesday 30 June 2026 — 2025–26 card: $118.00
Visit on Thursday 2 July 2026 — 2026–27 card: $124.00
Foam dressing × 2, at the insurer's price: 2 × $6.40 = $12.80
Invoice raised on 10 July, before any GST: $254.80
If that invoice is voided: Both visits and both dressings go back to unbilled
When it's invoiced again: The same prices — each visit keeps its own date's card

Demo figures. The price follows the service date, not the invoice date, and a card's last day counts in full — a 3 pm visit on 30 June still takes the old card. Voiding releases the lines for the next run.

In detail

The detail, on the real screens.

An episode of care, with the payer attached

An episode — a case, if that's your word — spans a date range and carries one funded piece of work for one patient: the appointments booked against it, the consumables recorded against it and its invoices. A note written on one of its visits joins it, and wounds, documents and letters can be filed on it. It names its payer, and optionally the payer's site, such as a ward or a facility; the payer's reference, the claim or participant number and the approval number; the referral source and the referrer's diagnosis as written. Funding sits on the episode in dollars, in visits or hours, or both, and the screen separates what has been used, meaning invoiced, from what is booked but not yet invoiced — both count against the limit. Expired is not Closed: expired means the funder's approval ran out and the work may resume on renewal; closed means it finished. The claim and approval numbers print on every invoice for the episode, and changing the approval number changes future invoices only — issued ones keep the number the funder will match on.

An episode of care in Corella, on an instance that uses the default word case: a diabetic foot ulcer episode for one person, open-ended, with its funding in dollars showing what is left, used and booked, a note that going over warns, who pays with their payment terms and a notice that no rate card is in force so standard prices apply, and the hospital-discharge referral

Every payer, at the price that applied on the day

Each payer — an insurer, a plan manager, a residential aged-care facility or home-care provider, a hospital, a GP practice, community health, a government funder such as DVA, TAC, WorkCover or state health, an employer, or the patient — carries its own sites, contacts, payment terms and billing email, and its own dated rate cards. The card in force on the service date sets the price, so the same visit dated either side of 1 July prices differently without anyone remembering to change something. A card's last day counts in full, each payer has one card in force on any date, and a card can be copied forward into a new period. Consumables can carry a per-payer price. Contracts and purchase orders sit beside the cards — a value, authorised visits or hours, an end date and your own warn-at percentage — and work booked but not yet invoiced counts against them. Per-payer cancellation rules set a notice window and whether a late cancellation is chargeable; the cancel dialog pre-selects the mode for a person to confirm.

Payers and rate cards in Corella: a demo insurer that requires a purchase order, with its 2026–27 schedule in force from 1 July; a residential aged-care facility with a 2026 facility agreement and two sites; and a GP practice and a self-funded lane with no rate card yet, falling back to the standard list — each with its payment terms

Wound measurements, charted — and read by your clinician

Your nurse measures the wound and types the numbers. Corella works out the area (length × width) and the volume (area × depth), the percentage change against that wound's own first measurement and against the previous one, draws the trend, narrows the comparison table to any date range and exports a CSV. Photographs sit in a timeline — several per visit — with the first and latest side by side. The clinician records the assessment in a structured way: the wound bed by percentage, undermining and tunnelling by clock position, exudate, periwound skin and edges, and an explicit “Did you assess for infection?”, where a blank reads Not recorded — kept apart from a no. An administrator edits the wound-bed descriptor scale in Settings, and each assessment keeps the wording it was made with. The figures are worked out afresh each time they're shown, so correcting a measurement corrects the history. In Australia, software that interprets a wound is a registrable medical device, so Corella keeps the record and your clinician makes every call about the wound — how it's progressing, when to review it, what the tissue is. Every wound trend, chart and comparison carries the product's label: “A record of what was measured. Not a clinical assessment.”

A wound care visit form on a phone: length, width and depth typed in millimetres, each marked Same as last visit, the area worked out as length times width, then the wound bed typed as percentages of granulation, slough and necrotic tissue — The nurse's numbers, and the area worked out from them

Visit forms, note templates and the clinical record

Forms → Starter templates installs nine clinical note templates — wound care, continence, catheter, gastrostomy, medication and injection, diabetes education, palliative, post-operative, and chronic care and wellbeing — each an ordinary form your team can edit. Field types include tick-many, where every option prints on the PDF ticked or not, a number with its unit, and a calculated field worked out on the server when the form is submitted. Switch on copy-forward for a template and the form starts from the same patient's previous visit, marking every answer still identical “Unchanged from the previous visit” — on screen, in the saved record and on the PDF — and leaving those answers off trend charts; signatures, photographs and calculated fields start fresh each visit. A section can be ruled not applicable for this visit, and the PDF says so. The patient's clinical record holds the charts, the wound body map and the medication record, and an administrator can chart a chosen form answer over time there, captioned “A record of what was recorded. Not a clinical assessment.”

Notes that lock, and corrections that show their working

A clinical note becomes final when your organisation's auto-lock window passes — 12, 24, 48 or 72 hours, or seven days — or when its author marks it final on the office notes screen. After that the lock has no override: not for the author, not for an administrator. A correction is an addendum — its own record, with a required reason, the author and the time — shown beneath the original, which stands. For supervised clinicians, the author can ask — from the office notes screen — one named senior colleague to countersign, or to send the note back with a reason, so review is recorded by name rather than assumed. Notes can carry required headings you set for each kind of note, a note written on a visit joins that visit's episode of care, and a note written up after the visit can be attached to the visit it belongs to. That's what makes a clinical note evidence: it stays exactly as written, and every correction shows.

Consumables that get billed exactly once

Dressings, PPE and continence aids live in a catalogue with pack sizes, suppliers, batch or lot numbers and expiry dates, plus named kits that go out together. Each item has a price, and a payer can have its own. Use is recorded against the patient — and, where it applies, the episode — from the office or clinical-lead screens. In Chrome or Edge, on Android or a computer, a packet's code or a batch's lot number can be scanned with the device camera. The part that matters at month end: an item is billed exactly once — an invoice run takes only unbilled use — and voiding the invoice releases it for the next run, so a dressing on a voided invoice goes into the next one. Stock a facility or the patient supplies is recorded and left off the bill, and an item marked not for sale is counted and left off the bill too.

The consumables catalogue in Corella: alginate rope, gauze, saline, a two-layer compression system, retention tape, foam and hydrocolloid dressings, gloves and a sharps container, each with its code, pack size, price per unit, batch-tracked flag and supplier

Stock on hand, in each place you keep it

Corella keeps a count of each consumable in each place you stock it — the store, a vehicle, one nurse's own bag — and the default place is preselected on a visit note. Receive, correct or write off stock by hand, and set a reorder point to get a low-stock alert overnight; the list marks each holding Low or In stock and heads with how many need attention. Stock comes out only when a use is recorded against a person, so every decrement says what it was used on.

Consumables in Corella's NDIS demo, on the Stock on hand tab: two places — Echuca clinic store, the default, and Car 1 (visits) — then seven holdings with their counts and reorder points, foam dressings and sterile saline marked Low in the car and the rest In stock, each with Adjust — A count in each place you keep stock, with a reorder point and a Low flag (NDIS demo)

Send a document from the record, and know whether it went

Nothing your organisation sends goes out until three separate switches agree, and one of them is ours: the email service configured on your instance, our approval of the instance, and your own switch — Corella's own sign-in emails aside. With email on, a coordinator can send a stored document from a patient's record — a report, a plan, an invoice PDF — with a covering message and up to ten more documents from the same patient's record, 20 MB in all. Each attachment is checked on the server; a document from another person's record, an archived one or one with no file is refused by name. Every send is logged — who sent it, when, to whom and what went — and a send that fails at the email step is logged as failed, which is the half that protects you: an unsent referral that nobody knows is unsent is worse than one that never left. A practice-wide Sent emails list, filterable by patient, sender and result, opens each email as it went. Mail goes from Corella's address under your organisation's name, with your email as the reply-to, and the Sent emails list is the record of every send.

The Sent emails list in Corella, from the NDIS demo: filters for participant, sender and result, then one row per email with the date and time, the document, the recipient, the participant, who sent it and the result — a Support at Home service agreement, Sent — The send log — to whom, what was sent, and whether it went

A recorded visit drafts the note — and the nurse finishes it

The visit scribe, off until your organisation switches it on, puts a Record the visit button above the nurse's note. The nurse tells the patient the visit is being recorded, records it on their phone, and a few minutes later the note arrives drafted into your organisation's own note headings, to read back, fix and save. Nothing is saved until they press Save, and they can discard the draft. The patient signs permission to be recorded first — the card offers it on the same device, there and then — and the scribe works on visits with one patient.

The Record the visit card on a nurse's phone in the wound care demo: permission needed before recording, with a button to get it signed now, then Record the visit and Upload a recording, and the line telling the nurse to tell the patient the visit is being recorded — the recording is turned into text and then discarded, and the draft lands in the note to read back, fix and save

A letter drafted from the record — gaps marked, signed by a person

A coordinator picks the kind of letter — to the GP or referrer, a referral to another clinician or service, a summary for the person or their family, or a letter of justification for equipment, consumables or ongoing care — and who it's addressed to, and can say what to include or leave out. The draft is written from this patient's record only: the profile, and the progress notes, forms, incidents, medication log and wound assessments of the last twelve months, and it cites what it used. Where the record is silent, the draft leaves a marked gap, and Finalise waits until every gap is filled. Whoever finalises the letter signs it under their own name and registration; it becomes a PDF in the patient's documents, ready to file on their episode of care, and a person sends it like any other document, through the send log above.

The Draft a letter from the record dialog in the wound care demo: it states the draft is written from this record only and that the assessing and advising stay with the person who signs it, that anything missing from the record is left as a marked gap, and that generating sends the record, office-only notes included, to the AI provider in the United States; below, the four kinds of letter, who it's addressed to, and what to include or leave out

Patients, nurses, episodes — and a preset to start from

Settings → Roster display sets the words: patient for the people you support, nurse for the people who do the work, episode of care for a case — each picked from a list or typed as your own, with all four forms of each word stored rather than derived, so “the patient's plan” and “Patients” both read correctly. Navigation, headings, filters, reports and report exports follow, the incident register's included. Web addresses stay as they are — /clients stays /clients — and it's a display setting, so your records stay exactly as they are: the interface follows your words, and printed documents use their own wording — a service agreement says the program's word (participant under the NDIS and Support at Home, client under CHSP), and yours for a private arrangement. Settings → Modules offers business-type presets, including one for community nursing and health clinics: expanding one previews what it turns on and off, Use this fills the switches, and nothing saves until you press Save. A starter library of thirty-three services installs unpriced on purpose, so every rate is yours to set. Each AI feature has its own switch, separate from any preset; where one is on, text is processed by our AI provider in the United States under terms that prohibit training on customer content, and speech is transcribed in the European Union, with your instance instructing deletion of the recording and its copy of the text.

Straight answers

Safety built in: what warns you, and what it stops.

Warns you

A visit that would take an episode's funding or a payer's contract near, to or over its limit — at booking, in dollars, visits or hours. It warns, and the booking stays your call.
A contract nearing its ceiling or its end date — an alert in the app, with a renewal window you choose (60 days unless you change it).
A payer reference the payer requires but the episode lacks — on the episode and in the invoice run, while the invoice goes ahead.
A payer with no rate card yet — the payers screen says prices fall back to your standard list.
A cancellation under a payer's rules — the dialog states the rule and pre-selects whether it's charged, for a person to confirm.

Stops you

Editing a locked note — anyone, the author and administrators included.
Two rate cards for the same payer with overlapping dates — the save is refused, so every service date has exactly one price.
Billing the same consumable twice — an invoice run takes only unbilled use.
Deleting an episode once anything is attached to it — it's closed instead.
Attaching another person's document to a send — refused by name.
A wound photograph without a current photography consent — where you've switched that gate on.

Who stays responsible

Your clinicians. The nurse measures, types, observes and decides; Corella records, does the arithmetic and keeps the prices and the dates straight. Every conclusion about a wound is the clinician's — in Australia, software that interprets a wound is a registrable medical device, and Corella's wound screens deliberately stay on the recording side of that line. Every wound trend, chart and comparison carries the product's own label: “A record of what was measured. Not a clinical assessment.”

The rulebook

Questions, answered properly.

In the help centre

What is the wound trend?

A record of what was measured — and the product says so on every trend, chart and comparison screen: a record of what was measured, not a clinical assessment. It is arithmetic on the numbers your clinician typed — area, volume and the change against that wound's own first measurement — presented back to them, and the interpretation is theirs. That's the line between clinical record-keeping software and a medical device that would have to be registered in Australia, and Corella stays clearly on the record-keeping side of it.

Who decides whether a wound is improving?

Your clinician. The moment software decides a wound has changed and says so, it is making a clinical judgement — and in Australia that makes it a registrable medical device, whatever disclaimer sits beside it. So Corella charts the numbers and your clinician reads the trend. The next review date your clinician sets on the wound's treatment plan sits on the wound record, so the team can book the review as a visit.

How are wound-bed descriptions recorded?

From a descriptor scale your clinicians pick from: Corella starts you with a short list, and an administrator edits the scale in Settings. Each assessment keeps the wording it was made with, even after the scale changes, and the words stay your clinician's record of what they saw.

Who can see wound photographs, and do we need consent?

Photographs stay on office and clinical-lead screens — kept off workers' shift screens and the family portal, because they usually show the patient's name on the ruler — and they're stored in your own Corella instance, hosted in Sydney. Each patient has a consent register for clinical photography, information sharing and telehealth: signed on screen, uploaded on paper or recorded as given verbally, with an optional expiry. An optional switch refuses a wound photograph without a current photography consent. Every measurement is typed by your clinician; the photograph is there to be looked at.

Does Corella write the nurse's notes or letters?

It drafts them; a person writes them. With the visit scribe on, a recorded visit comes back as a draft in your note headings for the nurse to read back, fix and save — nothing is saved until they do, and the patient signs recording permission first. A letter drafted from the record is saved as a draft that leaves a marked gap wherever the record is silent, and it is finalised once every gap is filled by the person signing it. Both are off until your organisation switches them on; the recording is transcribed in the European Union and deleted there once transcribed, and the drafting is done by our AI provider in the United States — for a letter, that means the patient's record, office-only notes included. Both draft from what was said and recorded, and the assessing and advising stay with your clinician — which keeps them on the record-keeping side of the line above.

Can a nurse fix a mistake in a locked note?

They add an addendum, with a reason, and the original stays visible above it. The lock has no override — for the author and administrators alike — because a clinical note is evidence only while it stays as written. Corrections become part of the record rather than a replacement for it, which is what a governance lead is checking for.

What happens when a payer's prices change on 1 July?

You add the new card from 1 July — or copy the old one forward and change the prices — and end the old card on 30 June. Corella keeps each payer's cards from overlapping, so every service date has exactly one price. A visit on 30 June takes the old card's price even if it's invoiced in August, a visit on 1 July takes the new one, and everything already invoiced keeps its price.

What if the funder's approval runs out partway through?

Mark the episode Expired rather than Closed: expired means the approval ran out and the work may resume on renewal; closed means it finished. You can still book against it, because a visit that happened before the approval lapsed still has to land somewhere — the booking drawer names the state and leaves the decision to you. Limits on the episode and on a payer's contract warn at booking, and an alert in the app warns before a contract runs out or runs over.

How does Corella handle consumables and stock?

Consumables are a catalogue with suppliers, batch and lot numbers, expiry dates, kits, per-payer prices and billing that happens exactly once, and Corella keeps a count of each item in each place you stock it — the store, a vehicle, one person's bag — with stock received, corrected or written off by hand and a reorder point that raises a low-stock alert overnight. Stock comes out when a use is recorded against a person, so every decrement says what it was used on, and expiry dates are tracked.

Can we prove what we sent, and to whom?

Yes. Every send from a patient's record is logged with who sent it, when, to whom and every attachment — so the log answers “what did we disclose?” — and the practice-wide Sent emails list opens each one as it went, with “Sent” meaning the email provider accepted it. Nothing goes out at all until three separate switches agree: the email service is configured on your instance, we have approved the instance, and your organisation has switched email on.

Can we invoice DVA, TAC or WorkCover?

Yes. DVA — like TAC, WorkCover or a state health program — can be a payer with its own rate card, and Corella raises the invoice to it at the price on that card.

Are episodes optional?

Yes. Episodes of care, payers, consumables and the wound screens are modules you switch on when you need them, so a provider running open-ended supports keeps a simpler set of screens. Turning episodes on leaves every existing price as it is until a visit is attached to an episode.
