I am planning to apply for licensing (application date: October 1, 2026) for a 20-bed assisted living facility for elderly patients with mild-to-moderate Alzheimer's disease. I need medical guidance on: 1) Nursing staff ratio per Saudi MOH regulations (1 RN per 8 patients day shift, 1 per 12 night shift, plus 1 geriatric psychiatrist on call) - confirm requirements and additional clinical staff needed. 2) Facility layout for dementia safety: circular walking path to prevent exit-seeking behavior, color-coded rooms (different pastel color per room for wayfinding), motion-sensor night lighting at 10 lux in hallways, secured garden minimum 100 m² with shaded seating - any additional safety requirements? 3) Medication management: automated dispensing cabinet with biometric access, controlled substance storage per MOH regulation for residents on memantine 10mg BID + donepezil 10mg daily + as-needed lorazepam 0.5mg - required documentation and protocols? 4) Activity therapy: structured daily schedule including music therapy 30 min, reminiscence therapy 45 min, gentle exercise 30 min, Snoezelen multisensory room 20 min - sufficient per dementia care standards? 5) Fall prevention: bed alarms, hip protectors for residents with osteoporosis T-score <= -2.5, non-slip flooring throughout - additional measures recommended? 6) Estimated operational cost projected at 15,000-20,000 SAR per bed per month - is this realistic for a medically compliant facility in Saudi Arabia?
