Summary : This figure presents two flowcharts outlining the pharmacological management of chronic obstructive pulmonary disease (COPD) based on the primary symptom: dyspnea or exacerbations. It details stepwise treatment escalation, decision points based on blood eosinophil counts, and additional therapeutic options. flowchart: # Dyspnea Management : Nodes : • LABA or LAMA (rounded rectangle) • LABA + LAMA* (rounded rectangle) • Consider switching inhaler device or molecules; Implement or escalate non-pharmacological treatment(s); Consider adding ensifentrine; Investigate (and treat) other causes of dyspnea (large rounded rectangle) Connectors : • Downward arrows from LABA or LAMA → LABA + LAMA* → management options box Layout : • Vertical, single branch, two main steps followed by a box with four bullet points # Exacerbations Management : Nodes : • LABA or LAMA (rounded rectangle) • LABA + LAMA* (rounded rectangle) • LABA + LAMA + ICS* (rounded rectangle) • Roflumilast (rounded rectangle, “FEV1 < 50% & chronic bronchitis”) • Azithromycin (rounded rectangle, “preferentially in former smokers”) • Dupilumab (rounded rectangle, “chronic bronchitis”) Connectors : • LABA or LAMA → LABA + LAMA* (if blood eos < 300) • LABA or LAMA → LABA + LAMA + ICS* (if blood eos ≥ 300) • LABA + LAMA* → LABA + LAMA + ICS* (if blood eos ≥ 100) • LABA + LAMA + ICS* → Roflumilast, Azithromycin, Dupilumab (branching arrows) • LABA + LAMA + ICS* → Dupilumab (if blood eos ≥ 300) Layout : • Vertical with multiple branches based on blood eosinophil count thresholds (<100, <300, ≥100, ≥300) • Final step branches into three parallel options # Additional Information : • Footnote: Single inhaler therapy may be more convenient and effective than multiple inhalers; single inhalers improve adherence to treatment. • Consider de-escalation of ICS if pneumonia or other considerable side-effects. In case of blood eos ≥ 300 cells/μl de-escalation is more likely to be associated with the development of exacerbations. • Exacerbations refers to the number of exacerbations per year. # Analysis : • The dyspnea pathway is linear, focusing on escalation and device/molecule switching, with consideration for non-pharmacological treatments and other causes. • The exacerbation pathway is more complex, with branching based on blood eosinophil counts, leading to different combinations of inhaled therapies and add-on treatments for specific patient subgroups (chronic bronchitis, former smokers, high eosinophil counts). • The figure emphasizes personalized treatment escalation and the importance of blood eosinophil count in guiding therapy for COPD exacerbations.

Summary : This flowchart outlines the stepwise management and treatment algorithm for osteoarthritis (OA) of the hip and/or knee, guiding clinicians from diagnosis through non-surgical and surgical interventions based on patient response. flowchart: # Nodes : • Start (rectangle): "Patient diagnosed with OA of the hip and/or knee" • Step 2 (rectangle): "Assess pain, severity, and functional limitations" • Step 3 (rectangle): "Develop individualized treatment plan with core non-surgical management approaches (see Sidebar 1)" • Step 4 (diamond): "Has the patient’s pain or functional limitation improved on re-evaluation?" • Step 5 (rectangle): "Continue long-term management of OA and reassess annually or as needed" • Step 6 (rectangle): "Offer referral to physical therapy and/or combination pharmacotherapy (see Sidebars 2 and 3)" • Step 7 (diamond): "Has the patient’s pain or functional limitation improved on re-evaluation?" • Step 8 (rectangle): "Referral for additional physical therapy" • Step 9 (diamond): "Has the patient’s pain or functional limitation improved on re-evaluation?" • Step 10 (rectangle): "Obtain weight-bearing plain radiographs prior to referral for surgical consultation (see Appendix K)" • Step 11 (rectangle): "Refer for surgical consultation" # Connectors : • Downward arrows connect each step in sequence unless otherwise specified. • From Step 4 (diamond): – "Yes" arrow to Step 5. – "No" arrow to Step 6. • From Step 7 (diamond): – "Yes" arrow to Step 5. – "No" arrow to Step 8. • From Step 9 (diamond): – "Yes" arrow to Step 5. – "No" arrow to Step 10. • Step 10 leads to Step 11. • Step 5 loops back to Step 7 for reassessment as needed. # Layout : • The flowchart is arranged vertically, with decision diamonds branching to the right or left for "Yes"/"No" answers, and merging back into the main flow. • There are three main decision points (Steps 4, 7, 9) that determine whether to continue current management, escalate therapy, or proceed to surgical evaluation. • The process allows for repeated reassessment and escalation based on patient response. # Analysis : • The algorithm emphasizes a stepwise, evidence-based approach, prioritizing non-surgical management and physical therapy before considering surgery. • Multiple reassessment points ensure that treatment is responsive to patient progress. • Only after failure of conservative measures and additional physical therapy, and after obtaining appropriate imaging, is surgical consultation recommended. • The flowchart supports individualized care and annual or as-needed reassessment for long-term management.

Summary : This flowchart outlines the stepwise management of Chronic Obstructive Pulmonary Disease (COPD) in primary care, including initial assessment, diagnosis, risk reduction, medication adjustment, and referral decisions. flowchart: # Nodes : • Start (rectangle): "Patient with chief complaint suggestive of COPD presents to primary care" • Rectangle: "Perform brief clinical assessment to determine if patient is clinically stable" • Diamond: "Is patient having an acute exacerbation? (see Sidebar 1)" • Ellipse: "Management of an acute exacerbation (see Module B)" • Rectangle: "Complete clinical assessment including consideration of common co-occurring conditions (see Sidebar 2): History, Exam, Evaluate for other contributing diagnoses, Obtain diagnostic spirometry if available" • Diamond: "Is there a confident clinical diagnosis of COPD?" • Rectangle: "Offer prevention and risk reduction methods including smoking cessation, vaccination, and patient education; Suggest spirometry if not already completed" • Rectangle: "Treat or refer as clinically indicated" • Diamond: "Is patient chronically symptomatic and/or has patient had a moderate to severe exacerbation in the past year? (see Sidebar 1)" • Rectangle: "If symptoms persist, consider need to initiate/adjust medication and assess inhaler technique (see Appendix G); ensure patient is on SABA (PRN), then use following steps for increasing intensity: 1. First line LAMA, 2. Add LABA for severe symptoms (preferably combination inhaler), 3. Add ICS only for continued moderate to severe exacerbations (see Sidebar 1), 4. Pulmonology referral" • Rectangle: "Consider need for oxygen if patient has resting hypoxemia (refer to home oxygen clinic if appropriate)" • Rectangle: "Continue follow-up and monitoring; Reassess severity periodically; Consider pulmonary rehabilitation; Consider medication adjustment if patient is on an inhaled corticosteroid (see Module C); Consider offering referral to a pulmonologist or a palliative care specialist as appropriate for patients with persistent refractory dyspnea; Carefully consider alternatives to beta blockers for non-cardiac indications (e.g., HTN)" # Connectors : • Arrows connect nodes in a top-down sequence, with diamonds representing decision points. • From "Is patient having an acute exacerbation?" (diamond): Yes → "Management of an acute exacerbation (ellipse)"; No → "Complete clinical assessment" (rectangle). • From "Is there a confident clinical diagnosis of COPD?" (diamond): Yes → "Offer prevention and risk reduction methods" (rectangle); No → "Treat or refer as clinically indicated" (rectangle). • From "Offer prevention and risk reduction methods" (rectangle) → "Is patient chronically symptomatic and/or has patient had a moderate to severe exacerbation in the past year?" (diamond). • From "Is patient chronically symptomatic..." (diamond): Yes → "If symptoms persist, consider need to initiate/adjust medication..." (rectangle); No → "Consider need for oxygen if patient has resting hypoxemia" (rectangle). • Both "If symptoms persist..." and "Consider need for oxygen..." nodes lead to "Continue follow-up and monitoring..." (rectangle). # Layout : • The flowchart is arranged vertically, with decision diamonds branching to different management paths. • Merges occur after medication adjustment and oxygen consideration, leading to a unified follow-up and monitoring node. • Sidebars and appendices are referenced for further detail at several steps. # Analysis : • The workflow prioritizes acute exacerbation management first, then proceeds to comprehensive assessment and diagnosis. • Preventive strategies and risk reduction are emphasized early for confirmed COPD cases. • Medication adjustment and specialist referral are considered for persistent symptoms or recent exacerbations. • Oxygen therapy is considered for patients with resting hypoxemia. • Ongoing follow-up, severity reassessment, and consideration of rehabilitation or specialist referral are recommended for all patients. • The flowchart supports a systematic, evidence-based approach to COPD management in primary care, with clear decision points and escalation pathways.
