Parent Fall Risk Home Assessment

Derivation Chain

Step 1 Parent caregiving & long-term care grade navigation

→

Step 2 Pre-care-grade stage: preventive care when parents don't yet qualify for formal care grades

→

Step 3 Systematically assess in-home fall risk factors and present improvement priorities

Problem

Fall accidents among seniors aged 70+ exceed 1 million cases annually, with fracture-related hospitalization costs averaging 5M-15M KRW (~$3,750-$11,250) and recovery periods of 3-6 months. When adult children aged 48-58 visit their parents' home, they sense hazards but have no systematic way to assess 'what exactly needs fixing and how.' While general fall prevention information exists, there is no personalized guide for 'what specifically to change in my parents' home.'

Solution

Users enter their parents' home environment (bathroom layout, flooring type, lighting, stairs, threshold heights, etc.) and parents' physical condition (vision, mobility aids, medication use) via a web checklist. The service generates (1) a prioritized risk factor list (urgent/caution/recommended improvement), (2) specific remediation steps for each risk factor with estimated costs (e.g., safety grab bar installation: 30,000-50,000 KRW / ~$23-$38), and (3) eligibility information for local government home modification subsidies. Differentiator: instead of vague 'be careful' advice, delivers actionable specifics like 'install a safety grab bar next to the toilet, cost ~40,000 KRW (~$30), with a link to search for installers.'

Target: Ages 48-58, living separately from parents aged 70+, whose parents still live independently but are beginning to experience physical decline

Revenue Model: Basic assessment (risk factor list): Free. Customized improvement report (prioritized actions + costs + subsidy eligibility PDF) per use: 4,900 KRW (~$3.70). Quarterly re-assessment reminder subscription: Free.
