Geriatrics Project Knowledge Skill
Purpose
Primary clinical reference corpus for SZMC geriatric ward practice.
Search before answering any clinical, pharmacological, legal, or regulatory question.
Source Hierarchy
| Priority | Source | Domain |
|---|
| 1 | SZMC DAG Antimicrobial Guidelines | Empiric antibiotic selection โ always overrides |
| 2 | Hazzard's Geriatric Medicine | Geriatric syndromes, pharmacology, aging physiology โ authoritative |
| 3 | Harrison's Internal Medicine | Pathophysiology, diagnosis, general internal medicine |
| 4 | Washington Manual of Therapeutics | Drug dosing, treatment algorithms, electrolyte protocols |
| 5 | Israeli MOH Circulars | Capacity law, surrogacy, ward licensing, driving fitness |
| 6 | Brookdale/JDC 65+ Statistics | Israeli epidemiology, prevalence, service benchmarks |
Rules:
- DAG overrides all for antibiotic selection at SZMC
- Hazzard's overrides Harrison's for geriatric-specific clinical management
- Israeli MOH law overrides textbooks for medico-legal decisions
- GRS removed from hierarchy โ superseded by Hazzard's + Harrison's
Source PDF Chapter References
Canonical TOC files (in the Geri repo, schema-guarded):
data/hazzard_chapters.json โ Hazzard 8edata/harrison_22e_toc.json โ Harrison 22e
These are the audited source-of-truth for q.ref validation.
question_chapters.json (.haz / .har fields) cross-references back into them.
Trust the JSON before any in-skill table.
TOC pre-flight is MANDATORY before any web Claude PDF prestage (Bot D
cluster-triage workflow): validate the target chapter against the TOC JSON
before extracting source quotes from the PDF. Skipping pre-flight risks
PDF-scan false positives that match body-text keywords instead of chapter
titles (vision_eye batch v1 picked Ch 14 "Models of Hospital Care" because
"eye" appeared in body text โ title-position match is the fix).
q.ref string format
When constructing or validating a q.ref value, use:
- Hazzard 8e:
Hazzard Ch <N> โ <TITLE>
- Harrison 22e:
Harrison 22e Ch <N> โ <Title>
The em-dash โ (U+2014) is required by hazzard_chapters.json schema-guard.
Hyphen-minus -, en-dash โ, trailing space, trailing colon, and
abbreviated/paraphrased titles all fail validation. Match the printed
chapter title in the PDF โ exact case, exact punctuation.
Verified chapters (working subset for fast reference)
This is a working subset surfaced during recent Bot D triage batches. The

Israeli Legal Framework โ Clinical Reference
1. ืืืคืื ืืื ืืชืืฉื (Lasting Power of Attorney)
MOH Legal Department circular, August 2023
Legal document (capacity required at signing, โฅ18 yo) appointing a proxy for
personal/financial/medical decisions when grantor loses capacity.
Medical scope (ืืืคืื ืืื ืจืคืืื or personal with health scope):
- Proxy can authorize urgent medical procedures without court order
- Proxy registers document + commitments with ืืืคืืืจืืคืืก ืืืืื
- Attending physician: allow emergency entry for urgent treatment even before
registration โ notify Registrar promptly after
Decision hierarchy before any incapacitated patient decision:
1. Active ืืืคืื ืืื ืืชืืฉื with medical authority โ activate proxy
2. Advance directives (ืื ืืืืช ืืงืืืืืช, s.35ื Capacity Law) โ follow
3. Neither โ ืืงืื ืืืืืืช ืืื ื process (see ยง2)
4. No family agreement โ court petition for ืืคืืืจืืคืืก
Physicians cannot initiate ืืืคืื ืืื โ patient must have presented it.
Check for existence before defaulting to family consensus.
2. ืืงืื ืืืืืืช ืืื ื (Temporary Medical Decision Maker)
Patient Rights Law Amendment 16, enacted 15.01.2024 โ MOH Medical Directorate circular
Purpose: Alternative to court for urgent (non-emergency) decisions when patient
cannot consent and no ืืืคืื ืืื / guardian exists.
Prerequisites โ all must be met:
- Patient cannot give informed consent
- Procedure is urgent (not emergency โ emergencies use 3-physician rule)
- No valid ืืืคืื ืืื / appointed ืืคืืืจืืคืืก for medical matters
- Family consensus exists on who should be surrogate
Step-by-step process (your clinical role):
Step 1 โ You (specialist physician):
- Determine urgent procedure is needed
- Document patient cannot consent
- Attempt accessibility accommodations per Disabilities Law
- If capacity uncertain โ consult psychiatrist or geriatrician
Step 2 โ ืขื"ืก (social worker, working hours):
- Verify no existing ืืืคืื ืืื or advance directives
- Convene family; achieve consensus on one surrogate
- Inform family of legal priority order (below)
- Obtain family signature on ื ืกืคื ื' (Declaration form)
Step 3 โ Hospital director or delegate:
- Reviews case
- Signs ื ืกืคื ื' (Authorization) โ authorization active
- All documentation โ patient chart; copy to surrogate
Family priority order (Patient Rights Law s.14b(a)):
spouse โ child โ parent โ sibling
(Agreement on different order permissible)
Validity: 6 months from signing, for all required procedures.
Re-check capacity before each procedure โ if patient consents directly, use that.
On discharge: Re-assess capacity; document current capacity status in discharge letter.
Parallel track: Family can still petition for ืืคืืืจืืคืืก during the 6-month period.
This tool does NOT apply when:
- Valid ืืืคืื ืืื ืืชืืฉื exists (including personal scope covering health)
- Appointed guardian already exists
- Family disagrees โ must go to court
3. ืกืืขืื ืืืจืื (Complex Nursing โ Geriatric Ward)
MOH Circular 4/2010, amended 14/3/23
Admission criteria โ must meet ALL:
