Dr. Catherine Marsh

Dr. Catherine Marsh provides comprehensive family medical care for a wide variety of health concerns affecting patients of all ages, including but not limited to:

Dermatological Skin Conditions

• Primary Care Skin Cancer Screening & Early Detection (Suspicious Mole/Lesion Assessment): Playing a vital primary care role in the early detection of skin cancer, which significantly improves prognosis, and facilitating prompt access to specialist dermatological care when needed.
• Eczema (Atopic Dermatitis), Contact Dermatitis & Seborrheic Dermatitis: Diagnosing and managing various forms of eczema/dermatitis, including atopic dermatitis (the most common type, often starting in childhood), irritant/allergic contact dermatitis (identifying and avoiding triggers), and seborrheic dermatitis (affecting scalp, face, chest). Management focuses on skincare education (frequent emollients, gentle cleansers, lukewarm baths), trigger identification and avoidance, topical corticosteroids (appropriate potency for site and severity), topical calcineurin inhibitors (TCIs like tacrolimus, pimecrolimus), and antihistamines for itch relief. Referral for patch testing or to dermatology for severe or refractory cases.
• Psoriasis (Mild to Moderate Plaque Psoriasis - Initial Management): Initial diagnosis and management of mild to moderate plaque psoriasis, providing topical treatments (potent topical corticosteroids, vitamin D analogues like calcipotriol, combination products, coal tar preparations, emollients) and lifestyle advice (stress management, identifying triggers). Screening for psoriatic arthritis symptoms. Referral to dermatology for moderate to severe psoriasis (requiring phototherapy or systemic/biologic agents), psoriatic arthritis, or diagnostic uncertainty.

Common Acute Conditions

• Acute Musculoskeletal Injuries (Sprains, Strains, Minor Back/Neck Pain): First-line care for everyday musculoskeletal injuries, supporting recovery, reducing pain and inflammation, restoring function, and providing referrals for imaging or physiotherapy if conservative measures are insufficient or red flags are present.

Adult Common Health Issues

• Benign Prostatic Hyperplasia (BPH) - Symptom Management & Monitoring: Management includes lifestyle advice (fluid management, avoiding bladder irritants), behavioral therapies (timed voiding), and prescription of medications such as alpha-blockers (e.g., tamsulosin, alfuzosin) to relax prostate/bladder neck muscles, or 5-alpha-reductase inhibitors (e.g., finasteride, dutasteride) to shrink prostate volume. Monitoring for symptom improvement and medication side effects.
• Venous Insufficiency & Varicose Veins (Conservative Management & Lifestyle Advice): Initial assessment and conservative management of symptoms related to chronic venous insufficiency (CVI) and varicose veins, such as leg aching, heaviness, swelling (edema), skin changes (e.g., hyperpigmentation, lipodermatosclerosis, venous eczema), and uncomplicated superficial thrombophlebitis. Ruling out deep vein thrombosis (DVT) if acute unilateral swelling/pain.
• Helicobacter pylori (H. pylori) Infection - Testing & Eradication Therapy: Confirmation of eradication testing post-treatment to ensure successful clearance of the infection and reduce risks of H. pylori-related gastroduodenal diseases.

• Gout & Pseudogout (Crystal Arthropathies) - Acute Attack Management & Chronic Prevention Strategies: Providing long-term management strategies for chronic gout to prevent recurrent attacks and complications (e.g., tophi, chronic gouty arthropathy, kidney stones), including detailed lifestyle advice (dietary modifications - reducing purine-rich foods such as red meat/organ meats/shellfish, limiting alcohol especially beer and spirits, avoiding sugary drinks/high-fructose corn syrup; hydration; weight management if overweight/obese) and initiating/managing urate-lowering therapy (ULT) such as allopurinol or febuxostat to achieve and maintain target serum uric acid levels (typically <360 µmol/L or <300 µmol/L if tophi present). Monitoring for medication side effects, adherence, and regular serum uric acid levels.
• Polymyalgia Rheumatica (PMR) - Diagnosis, Management & Monitoring (Often with Rheumatology Co-Management): Long-term management of PMR involves a very slow and gradual tapering of corticosteroids over 1-2 years (or longer), carefully monitoring for clinical relapse (recurrence of symptoms) and adjusting steroid dose accordingly.

At CLSC Chertsey, family medicine is centered on a collaborative partnership to help individuals like you achieve significant improvements in your health, manage ongoing conditions effectively, and enhance your overall well-being. Dr Marsh frequently works with patients towards goals such as:

• Dr Marsh understands the impact of their baby needing their scheduled well-baby visit to check growth and get their important vaccinations. That's why treatment is geared towards receiving proactive preventative care and targeted health screenings from Dr Marsh that very likely averted a more serious, costly, or even life-threatening health issue from developing unnoticed or progressing to an advanced stage, helping patients get back to confidently enjoying a varied, balanced, and largely unrestricted diet (unless medically indicated for very specific diagnosed conditions like celiac disease or severe allergies) without undue fear of triggering adverse reactions, pain, or significant digestive distress with greater ease.
• For patients where wanting to discuss various birth control options to find what's best for them, or needing a Pap test is a concern, Dr Marsh focuses on plans that lead to managing bothersome and often disruptive menopausal or perimenopausal symptoms (like hot flashes, sleep issues, or mood changes) effectively with Dr Marsh's expert guidance and tailored treatment options, leading to improved well-being, better sleep, and a smoother, more comfortable life transition, supporting their ability to spontaneously making and eagerly keeping enjoyable plans with a wide circle of friends for various social outings such as dinners out, casual coffee chats, shared recreational activities, or weekend excursions.

Your personalized healthcare plan, developed in discussion with Dr Marsh, will be thoughtfully designed to help you reach your specific functional, preventative, and wellness objectives. She believes in empowering patients with the knowledge and support needed to take an active role in their health journey.

Is seeing a family doctor (Médecin de famille) covered by Régie de l&#x27;assurance maladie du Québec (RAMQ) in QC?

Medically necessary visits to a family doctor are typically covered by the Régie de l'assurance maladie du Québec (RAMQ) for eligible residents with a valid provincial health card. However, some services (e.g., cosmetic procedures, most travel medicine consultations, sick notes for work/school, insurance forms, driver's medicals) may not be covered and might have an associated fee. Please confirm with CLSC Chertsey if you have questions about specific non-insured services or potential fees.

How often should I see Dr Marsh for a check-up or physical exam?

The recommended frequency for check-ups varies based on your age, overall health, existing conditions, and risk factors. Generally, healthy younger adults may need check-ups less frequently (e.g., every 2-5 years if no concerns), while children, older adults (e.g., annually over 65), or those with chronic conditions may benefit from more frequent visits (e.g., annually or semi-annually). Dr Marsh follows established provincial guidelines for specific screening tests. Discuss your individual needs with her to determine an appropriate schedule.

Do I need a referral to see a family doctor (Médecin de famille) in QC?

Generally, you don't need a referral to see a family doctor if they are accepting new patients. However, finding a family doctor who is accepting new patients can be challenging. Provincial resources or the College of Physicians and Surgeons of Quebec may be helpful. A referral is usually required to see specialists.

How can I find a family doctor (Médecin de famille) in QC who is accepting new patients?

Check the College of Physicians and Surgeons of Quebec website for a 'Find a Doctor' tool. Ask friends, family, or colleagues for recommendations. Contact local community health centres or new patient clinics. It can be challenging and may take time.

What does 'preventative care' involve with a family doctor like Dr Marsh?

Preventative care with Dr Marsh focuses on keeping you healthy and identifying potential health problems before they become serious. This involves services tailored to your age, gender, and risk factors, such as routine check-ups, age-appropriate cancer screenings, immunizations, blood pressure and cholesterol checks, diabetes screening, counseling on healthy lifestyle choices, and risk assessments. The goal is to prevent illness and detect diseases early.

What exactly is a family doctor (Médecin de famille) and what is their role?

A family doctor, or general practitioner (GP), is a medical doctor specializing in comprehensive primary healthcare for individuals and families of all ages. They serve as your first point of contact for most health concerns, offering preventative care, diagnosing and treating illnesses, managing chronic conditions, providing mental health support, and coordinating care by referring you to specialists when necessary. Building long-term relationships with patients is a key aspect of their role.
