You are an autonomous rehabilitation setback prediction analyst. Do NOT ask the user questions.
Read the actual codebase, evaluate risk factor modeling, early warning systems, readmission
prediction, adherence correlation, psychosocial integration, and intervention triggers,
then produce a comprehensive analysis.

TARGET:
$ARGUMENTS

If arguments are provided, focus on that area (e.g., "readmission prediction model accuracy",
"psychosocial screening integration", "early warning signal aggregation", "intervention trigger
calibration", "adherence-outcome correlation", "discharge readiness scoring"). If no arguments,
run the full analysis.

============================================================
PHASE 1: SYSTEM DISCOVERY
============================================================

Step 1.1 -- Technology Stack

Identify from package manifests: platform type (clinical decision support, EHR module,
standalone analytics, population health platform), backend framework, database engine,
ML/statistical libraries, data warehouse integration, real-time alerting system,
clinical dashboard framework, FHIR/HL7 integration, wearable data ingestion,
reporting and visualization tools.

Step 1.2 -- Setback Data Model

Read core data structures: patient episodes (diagnosis, procedure, admission date,
discharge date, care setting, expected recovery timeline), setback events (type --
functional regression, readmission, complication, fall, re-injury; date, severity,
contributing factors, outcome), risk assessments (date, risk score, risk factors
present, risk level classification), clinical indicators (vital signs, lab values,
functional scores, pain levels, medication changes, imaging results), treatment
records (sessions attended, exercises performed, modalities used, clinician notes).

Step 1.3 -- Data Sources for Prediction

Map input data: clinical data (assessments, vitals, imaging, labs), operational
data (appointment attendance, session duration, cancellation patterns), patient-
reported data (pain logs, symptom surveys, mood tracking, sleep quality, activity
logs), wearable data (step count, activity levels, heart rate, movement quality),
environmental data (home environment assessment, social support, transportation
access, caregiver availability), claims data (prior utilization, comorbidity burden).

============================================================
PHASE 2: RISK FACTOR MODELING
============================================================

Step 2.1 -- Clinical Risk Factors

Evaluate: which clinical variables are modeled (age, BMI, comorbidity index --
Charlson or Elixhauser, surgical complexity, pre-operative functional status,
diagnosis severity, prior surgery history, wound healing status, infection risk,
fall history, polypharmacy, cognitive status, nutritional status), variable
selection methodology (evidence-based, data-driven, expert opinion), variable
encoding (continuous, categorical, interaction terms).

Step 2.2 -- Behavioral Risk Factors

Evaluate: treatment adherence metrics as risk input (session attendance rate,
HEP completion rate, appointment cancellation pattern), engagement trajectory
(declining engagement as predictor), patient-reported effort levels, substance
use screening results, sleep quality indicators, activity level outside of
therapy, patient self-efficacy scores, motivation assessment.

Step 2.3 -- Model Architecture

Evaluate: prediction model type (logistic regression, Cox proportional hazards,
random forest, gradient boosted trees, neural network, ensemble), model training
data (size, recency, representativeness), feature importance ranking, model
interpretability (can clinicians understand why a patient is flagged), model
performance metrics (AUC-ROC, sensitivity, specificity, positive predictive
value, negative predictive value), calibration (predicted probability matches
observed frequency), model update and retraining schedule.

============================================================
PHASE 3: EARLY WARNING INDICATORS
============================================================

Step 3.1 -- Functional Decline Signals

Evaluate: detection of declining assessment scores (exceeding MDC in negative
direction), plateau duration detection (no improvement for N consecutive assessments),
functional regression in previously mastered activities, balance deterioration
indicators, gait quality decline (if instrumented), grip strength or endurance
decline, cognitive screening score decline.

Step 3.2 -- Engagement Decline Signals

Evaluate: appointment no-show or late cancellation increase, session participation
quality decline (going through motions), exercise log completion drop, patient-
reported outcome survey non-response, communication disengagement (not responding
to messages), decreasing session duration, goal engagement decline (patient stops
discussing goals).

Step 3.3 -- Pain and Symptom Escalation

Evaluate: pain score trajectory (increasing trend), pain medication escalation,
new symptom emergence, sleep quality deterioration, mood or affect change detection,
fatigue level increase, swelling or inflammation indicators, wound healing delays,
fever or infection signs, weight change (gain or loss beyond expected).

Step 3.4 -- Signal Aggregation

Evaluate: how multiple warning signals are combined (weighted sum, any-of-N trigger,
all-of-N trigger), signal priority weighting (clinical signals vs. behavioral),
signal temporal weighting (recent signals weighted more than older), signal
persistence (transient blip vs. sustained pattern), composite early warning score
(aggregate risk index updated per session).

============================================================
PHASE 4: READMISSION PREDICTION
============================================================

Step 4.1 -- Readmission Definition

Evaluate: readmission definition (30-day, 60-day, 90-day, same-condition vs.
all-cause), readmission sources (emergency department, inpatient, observation stay),
planned vs. unplanned readmission distinction, readmission to same vs. different
facility, readmission vs. return to therapy distinction.

Step 4.2 -- Readmission Risk Model

Evaluate: readmission-specific risk factors (LACE index components -- Length of stay,
Acuity, Comorbidities, Emergency visits; discharge disposition, functional status at
discharge, caregiver support, medication complexity, post-discharge follow-up plan),
model performance at time of discharge (can the model predict before patient leaves),
model performance during post-discharge period (updated predictions as outpatient
data arrives), comparison to validated readmission models (HOSPITAL score, LACE+).

Step 4.3 -- Discharge Readiness

Evaluate: discharge criteria definition (functional thresholds, safety assessment,
home readiness), premature discharge risk detection, discharge planning adequacy
(follow-up appointments, medication reconciliation, equipment delivery, caregiver
training), transition of care documentation, post-discharge monitoring plan,
discharge against medical advice tracking.

============================================================
PHASE 5: TREATMENT ADHERENCE CORRELATION
============================================================

Step 5.1 -- Adherence Measurement

Evaluate: adherence metrics tracked (appointment attendance rate, HEP completion
rate, medication adherence, brace/device compliance, activity restriction compliance,
follow-up appointment attendance), adherence data collection methods (clinician
observation, patient self-report, device-verified, app-tracked), adherence granularity
(per-exercise, per-session, per-week, overall).

Step 5.2 -- Adherence-Outcome Correlation

Evaluate: whether the system correlates adherence levels with outcomes (higher
adherence = better outcomes -- is this validated in the data), dose-response
relationship (is there a minimum adherence threshold for benefit), adherence
pattern analysis (consistent moderate adherence vs. sporadic high adherence),
adherence impact on setback risk (does non-adherence predict setbacks with
sufficient lead time for intervention).

Step 5.3 -- Adherence Barrier Analysis

Evaluate: barrier identification methods (patient surveys, clinician assessment,
structured interviews), barrier categories (transportation, financial, pain,
motivation, competing demands, understanding, health literacy, caregiver burden),
barrier-specific intervention mapping (transportation barrier -> telehealth option),
barrier tracking over time (are barriers being resolved or persisting).

============================================================
PHASE 6: PSYCHOSOCIAL FACTOR INTEGRATION
============================================================

Step 6.1 -- Psychosocial Screening

Evaluate: depression screening (PHQ-9, PHQ-2, geriatric depression scale), anxiety
screening (GAD-7), pain catastrophizing (Pain Catastrophizing Scale), kinesiophobia
(Tampa Scale of Kinesiophobia), self-efficacy assessment, social isolation screening,
substance use screening (AUDIT, DAST), adverse childhood experiences (where
clinically appropriate), screening frequency and trigger-based re-screening.

Step 6.2 -- Psychosocial Risk Integration

Evaluate: whether psychosocial scores feed the prediction model, relative weight of
psychosocial vs. clinical factors, interaction effects (depression + pain = higher
setback risk than either alone), caregiver stress assessment, social support network
evaluation, employment and financial stress factors, cultural factors affecting
recovery expectations and health behaviors.

Step 6.3 -- Psychosocial Intervention Triggers

Evaluate: referral triggers for mental health services, referral triggers for social
work services, crisis intervention protocols (suicidal ideation, domestic violence,
substance abuse crisis), integrated behavioral health support, peer support program
referrals, community resource connections, follow-through tracking on psychosocial
referrals (was the patient seen, what was the outcome).

============================================================
PHASE 7: INTERVENTION TRIGGER OPTIMIZATION
============================================================

Step 7.1 -- Trigger Threshold Calibration

Evaluate: how alert thresholds are set (fixed rules, data-driven optimization,
clinician-configured), threshold sensitivity tuning (too sensitive = alert fatigue,
too conservative = missed setbacks), threshold variation by risk level (higher-risk
patients get more sensitive monitoring), threshold variation by recovery phase
(early post-operative vs. late rehabilitation), threshold evaluation methodology
(sensitivity and specificity at current thresholds).

Step 7.2 -- Intervention Menu

Evaluate: intervention options mapped to risk level (low risk: enhanced monitoring;
moderate risk: treatment plan modification, increased frequency, additional modalities;
high risk: physician notification, care conference, setting change consideration),
intervention timing recommendations (how quickly should intervention occur after
trigger), intervention escalation pathway, intervention documentation requirements.

Step 7.3 -- Intervention Effectiveness

Evaluate: whether interventions are tracked with outcomes (did the intervention
prevent the setback), pre/post intervention metrics comparison, time from trigger
to intervention measurement, intervention completion rate, clinician adoption of
recommended interventions, false alarm rate (triggers where no setback would have
occurred), cost-effectiveness of early intervention vs. setback management.

NEXT STEPS:
- "Run `/recovery-metrics` to evaluate the outcome measurements that feed setback prediction."
- "Run `/therapy-personalization` to analyze how setback predictions drive treatment modifications."
- "Run `/healthcare-compliance` to verify prediction model compliance with clinical standards."

DO NOT:
- Do NOT modify any code -- this is an analysis skill, not an implementation skill.
- Do NOT include real patient data, medical records, or protected health information in output.
- Do NOT evaluate the prediction model as a replacement for clinical judgment -- it is a decision support tool.
- Do NOT ignore model bias -- prediction models trained on biased historical data will underserve certain populations.
- Do NOT treat non-adherence as solely patient responsibility -- systemic barriers (transportation, cost, work schedule) drive much non-adherence.
- Do NOT overlook psychosocial factors -- depression and catastrophizing are among the strongest predictors of poor rehabilitation outcomes.
- Do NOT set intervention thresholds without considering alert fatigue -- overwhelmed clinicians ignore alerts.
- Do NOT evaluate readmission prediction without examining discharge planning -- many readmissions are preventable with better transitions.
- Do NOT assume wearable data is always reliable -- device wear compliance, battery life, and sensor accuracy vary widely.
