aurahack HackitRx 2026 problem statement files PS2 Three versions

The problem statement files

Our PS2 problem statement has changed twice. It started as the Haemophilia Society of Singapore's brief, became the version we took to the Hackers Roundtable after our interviews, and dropped off-hours as its boundary after the Roundtable feedback.

The original problem statement, from HSS

Submitted by the Haemophilia Society of Singapore and published on the HackitRx 2026 problem statements page. Set here as published.

Bleed guidance at 2am on a Sunday

Bleeds don't keep within clinic hours. When one happens at night, on a weekend, or on a public holiday, families rely on memory of what a nurse said months ago, WhatsApp peer advice, or Google. Site-specific first aid (a joint bleed is not a muscle bleed is not a gum bleed) is hard to recall under stress, so families defer reporting until Monday, and delay raises the risk of long-term joint damage.

Read as four parts

Who
Families: people with haemophilia and the people who look after them.
When
At night, on a weekend, or on a public holiday.
The problem
Recalling site-specific first aid under stress, with only memory, WhatsApp and Google to go on.
The risk
Reporting deferred until Monday, and long-term joint damage from the delay.
Version 2Hackers Roundtable, 13 Sep 2026

The Roundtable problem statement

What we presented at the Hackers Roundtable, after desk research and interviews with two adult patients and a haemophilia nurse between 6 and 9 Sep.

Adults with moderate to severe haemophilia need to assess, decide and manage unfamiliar acute bleeds confidently when care teams are unavailable after hours. Without trusted & contextualised guidance readily available, this can lead to guesswork, delayed or suboptimal treatment and recovery, increasing the risk of permanent joint damage or serious complications.

WhoWhatWhenWhyImpact

Despite high adherence, acute bleeds still happen.

80%adhere to prophylaxis 85%still bled last year, six breakthrough bleeds a year on average, half needing hospital

The off-hours acute care gap widens that burden.

Unfamiliar situation+Time-sensitive decision+Off-hours isolation=Cognitive overload & clinical risk

Off-hours isolation: no clinician reachable until Monday.

What changed from the HSS brief

  1. 1

    Who narrowed to adults with moderate to severe haemophilia.

    Both patients we interviewed were severe adults, and the nurse's cohort is severe adults on prophylaxis, whose caregivers almost never call her.

  2. 2

    The problem moved from recalling first aid to unfamiliar bleeds.

    Experienced adults are on autopilot with the bleeds they know, and recognising a bleed is mostly solved. The hard case is a bleed that does not match their routine.

  3. 3

    The problem runs past the first dose.

    The uncertainty sits after the first infusion and into the recovery that follows, so recovery entered the impact.

  4. 4

    Off-hours stayed as the boundary.

    The gap was still defined by time: no clinician reachable until Monday.

Version 3Current

The current problem statement

Agreed after the Roundtable feedback and further alignment as a team: we no longer focus on off-hours.

Adults with moderate to severe haemophilia need to assess, decide and manage unfamiliar acute bleeds confidently, when care teams are unavailable after hours whenever they happen. Without trusted & contextualised guidance readily available, this can lead to guesswork, delayed or suboptimal treatment and recovery, increasing the risk of permanent joint damage or serious complications.

What changed from the Roundtable version

  1. 1

    The after-hours clause is gone.

    Bleeds happen at any hour. The problem is the same at 2pm as at 2am, so the statement no longer names a time.

  2. 2

    An open clinic does not solve it.

    The interviews showed patients do not want to escalate every bleed to the clinic. Whether to escalate, and whether to report a bleed to the care team, is the patient's call each time.

  3. 3

    Reaching the care team is a branch, not the boundary.

    Whether the care team can be reached is one step inside the decision, not the edge of the problem.

  4. 4

    Who, what and the risk stay.

    Adults with moderate to severe haemophilia, unfamiliar acute bleeds through treatment and recovery, and the risk of permanent joint damage carry over unchanged.
