Three versions

The problem statement files

Our PS2 statement changed twice: HSS's original brief, the version taken to the Hackers Roundtable, then the final version.

Version 1The starting point

The original problem statement, from HSS

Submitted by the Haemophilia Society of Singapore, published on the HackitRx 2026 problem statements page.

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.

Version 2Hackers Roundtable, 13 Sep 2026

The Roundtable problem statement

Presented at the Hackers Roundtable, after desk research and interviews with two adult patients and a haemophilia nurse, 6 to 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.

The off-hours gap adds to that burden.

Final version

The final problem statement

Problem Statement

When adults with severe haemophilia have a suspected or unfamiliar bleed particularly when immediate care team support is unavailable, they lack contextual guidance on what to do next. This can lead to high-stakes guesswork, delayed factor treatment and poor recovery that risk permanent joint damage.

Our Solution

Bleedwise helps people with haemophilia navigate uncertain bleeding episodes with greater confidence, starting from symptom recognition and contextualised guidance to treatment monitoring, and care-team communication.
