Sop For Diagnosis Of Top 20 Common Diseases Updated

STANDARD OPERATING PROCEDURE (SOP)

This SOP applies to all general physicians, nurse practitioners, and triage nurses. The "Top 20" diseases are defined by annual patient volume from our EMR:

Phase II: The Diagnostic Tier System

The core of this SOP is the "Diagnostic Tier System," which stratifies the diagnostic process based on clinical probability and test availability. This prevents the "shotgun approach" to testing, which drives up costs. sop for diagnosis of top 20 common diseases updated

Develop a workflow for primary care?

• Tier 1: Clinical Diagnosis (Empiricism): Many of the Top 20 diseases, such as migraine, tension headaches, or initial presentations of depression, are primarily clinical diagnoses. The SOP dictates that for these conditions, diagnosis relies on established criteria (e.g., ICHD-3 for headaches or DSM-5 for mental health) without mandatory imaging or invasive labs, provided red flags are absent.
• Tier 2: Bedside and Point-of-Care Testing (POCT): For conditions like influenza, streptococcal pharyngitis, or urinary tract infections, the SOP mandates rapid antigen testing or urinalysis. This tier allows for immediate confirmation and treatment, reducing the "wait and see" period.
• Tier 3: Laboratory and Radiological Confirmation: When Tier 1 and Tier 2 are inconclusive, or for conditions requiring strict numerical thresholds (e.g., Type 2 Diabetes requiring HbA1c > 6.5%, or Hypertension requiring persistent elevated BP), the SOP dictates specific confirmatory tests. For respiratory conditions like asthma or COPD, spirometry is the required gold standard before a diagnosis is formally codified in the patient record.

• Step 1: PHQ-9 questionnaire (score ≥10 suggests major depression).
• Step 2: Clinical interview: Rule out bipolar (hypomania screening via MDQ).
• Step 3: Physical: TSH, vitamin B12, CBC (rule out medical causes).
• Step 4: Collateral information from family (duration, functional impairment).
