Wound Care Documentation After Excisional Skin Surgery
- Excisional skin surgery, including standard excision of melanoma, squamous cell carcinoma, and basal cell carcinoma, produces a sutured wound that requires specific post-operative wound care for 1 to 2 weeks depending on the location and closure type. Discharge instructions for sutured wound care must specify: the frequency and method of wound cleaning (typically once daily with saline or dilute hydrogen peroxide at the provider's discretion), the type of dressing to apply and how to apply it, the specific signs of wound infection to watch for (increasing redness beyond the wound margin, purulent discharge, fever above 101 degrees Fahrenheit, increasing pain after the second post-operative day), and the timeline for suture removal based on wound location. Suture removal timing varies by anatomic site: scalp sutures are typically removed at 7 to 10 days, trunk and extremity sutures at 10 to 14 days, and leg sutures, which heal more slowly due to circulatory factors, at 14 to 21 days.
- Activity restrictions after excisional skin surgery must be specific to the wound location and closure type. A patient with a large excision on the upper back should receive instructions limiting overhead arm movement and heavy lifting for 2 to 3 weeks, because tension on the wound from shoulder movement is a primary cause of wound dehiscence after back excisions. A patient with a leg excision should receive instructions about elevation of the leg when sitting and the avoidance of prolonged standing or walking during the first week, because gravity-dependent edema impairs wound healing in lower extremity wounds. Generic activity restrictions that do not account for wound location are a documentation gap that can contribute to dehiscence claims when the restriction the patient needed was not specified.
- Sun protection instructions are a required component of discharge documentation for any skin surgery patient. Scar tissue lacks the melanocyte density of surrounding skin and does not tan uniformly. UV exposure to a healing or immature scar causes permanent hyperpigmentation that is difficult to treat. Discharge instructions should specify: no direct sun exposure to the wound or scar for at least 6 months after surgery, sunscreen application of SPF 30 or greater to the healed scar whenever it will be exposed to sun, and physical sun protection (hats, protective clothing) for scalp, face, and neck wounds. The American Academy of Dermatology (AAD) guidelines for wound care after skin surgery endorse these sun protection recommendations. Instructions that do not include sun protection guidance create a documentation gap for post-surgical dyspigmentation complaints.
- Pathology follow-up instructions must be included in discharge documentation for all procedures in which tissue was submitted for pathological analysis. The instructions should specify: that the patient will receive a call or message with pathology results (typically within 5 to 10 business days), the patient's responsibility to contact the office if they have not received results within the specified timeframe, and the planned management if the pathology shows specific findings such as positive margins on an excision. Failure to document that pathology follow-up instructions were given, and failure to have a system for tracking unreported pathology results, is a recurring source of malpractice claims in dermatology practices.
Aftercare Instructions for Mohs Micrographic Surgery
- Mohs micrographic surgery produces larger wounds than standard excision because the technique removes sequential tissue layers with complete margin assessment, and reconstruction may involve primary closure, flaps, grafts, or second-intention healing depending on defect size and location. The complexity of Mohs surgery aftercare documentation reflects the range of reconstruction types. Discharge instructions must be specific to the reconstruction performed, not generic wound care instructions. A patient with a skin graft needs different instructions than a patient with a primary closure of a similar-sized defect, and a patient left to heal by second intention needs different instructions than either.
- For wounds healing by second intention, discharge instructions must specify: the wound care regimen (typically petrolatum-based ointment applied to the wound under a non-adherent dressing, changed daily), the expected appearance of the wound at each stage of healing (pink granulation tissue in the first 2 to 3 weeks, gradual wound contraction over 6 to 8 weeks), the expected time to complete re-epithelialization based on wound size and location (smaller wounds on the scalp may heal in 4 to 6 weeks; larger wounds on the leg may take 12 or more weeks), and the signs of impaired healing that require provider evaluation. Patients who have not received a clear description of what normal healing looks like frequently present to the office or to urgent care reporting what they believe are signs of infection when the wound is actually healing normally.
- Skin graft aftercare requires specific instructions about immobilization of the graft site during the first week, when graft vascularity is being established. A Bolster dressing or tie-over dressing applied to secure the graft in the operating room is typically left in place for 5 to 7 days. Discharge instructions should specify: that the Bolster dressing should not be disturbed at home, that any drainage at the graft margins is expected and should be assessed by the provider if it increases significantly, that the patient should avoid activities that move the underlying skin at the graft site (for example, facial expression movements for facial grafts, or bending and flexion for extremity grafts), and the appointment date for the first post-operative dressing removal. The American College of Mohs Surgery (ACMS) training materials address graft aftercare as a standard element of Mohs fellow training.
- Post-operative bleeding is the most common early complication of Mohs surgery requiring emergency contact. Discharge instructions must include a specific protocol for managing post-operative bleeding: apply firm continuous pressure to the wound for 20 minutes without lifting the dressing to check the wound, call the practice's after-hours line if bleeding does not stop with 20 minutes of pressure, and go to the emergency department if pressure does not control bleeding. Practices performing Mohs surgery must have an after-hours contact mechanism and must document that patients received this contact information at discharge. Instructions that tell a patient to go directly to the emergency room for any bleeding, without specifying a pressure protocol first, lead to unnecessary emergency department visits and create patient satisfaction and care coordination problems.
Post-Procedure Instructions for Laser and Energy-Based Treatments
- Laser and energy-based device treatments in dermatology include ablative fractional laser resurfacing (CO2 and erbium lasers), non-ablative fractional lasers, intense pulsed light (IPL), laser hair removal, and laser treatment of vascular lesions. Each device category produces a distinct tissue response and requires procedure-specific aftercare instructions. A patient who receives ablative fractional CO2 resurfacing requires instructions for managing an open wound with serosanguineous exudate for 4 to 7 days, while a patient who receives non-ablative fractional laser treatment has intact skin and requires only moisturizer and sun avoidance. Generic laser aftercare instructions that do not distinguish between ablative and non-ablative treatment are a significant documentation gap.
- Ablative laser resurfacing aftercare instructions must address: the wound care regimen during the open wound phase (closed moist wound healing with petrolatum or silicone-based ointment under occlusive dressing until re-epithelialization, typically 5 to 7 days for CO2 ablative fractional), the expected appearance of erythema after re-epithelialization (persistent redness that typically resolves over 3 to 6 months, more prolonged in darker skin types), sun avoidance and sunscreen requirements starting at day 7 after healing, and the signs of infection during the wound phase (fever, purulent exudate, foul odor, rapid extension of redness beyond the treated area). Herpes simplex virus (HSV) reactivation after facial ablative laser resurfacing can cause widespread skin ulceration and permanent scarring if not treated within 24 hours. Discharge instructions for any patient with a history of oral HSV must document whether antiviral prophylaxis was prescribed, and instructions for all facial ablative laser patients must include HSV reactivation warning signs.
- Laser hair removal and laser treatment of vascular lesions produce a post-treatment response that includes localized erythema, edema, and sometimes purpura (for pulsed dye laser treatment of vascular lesions). Discharge instructions must specify: expected post-treatment skin changes by type and timing (for pulsed dye laser for port-wine stain, purpura lasting 7 to 14 days is expected and does not indicate a complication), cooling instructions for the first 24 hours after treatment (cool compress application for 10 to 15 minutes at a time, not ice directly on skin), sun avoidance during the treatment course, and the signs of burns or blistering that require prompt provider evaluation. Blistering after laser hair removal indicates that the treatment parameters were at or above the threshold for epidermal injury, and discharge instructions must specify that blistering requires same-day contact with the practice for wound care guidance.
- Chemical peel aftercare requirements depend on the depth of the peel: superficial peels (glycolic acid, salicylic acid, Jessner's solution) produce exfoliation without open wound formation; medium-depth peels (trichloroacetic acid 35 percent, Jessner's and TCA combination) produce more significant exfoliation and temporary crusting; and deep peels (phenol-based peels) produce an open wound comparable to a burn injury and require wound care comparable to ablative laser resurfacing. Instructions for medium-depth and deep chemical peels must specify: the wound care regimen specific to the depth treated, sun avoidance for at least 6 months after re-epithelialization, moisturizer and sunscreen application on healed skin, and the risk of post-inflammatory hyperpigmentation particularly in Fitzpatrick skin types III through VI. Patients with darker skin types must receive specific counseling and written documentation that hyperpigmentation risk increases with peel depth.
Cryotherapy and Biopsy Aftercare Documentation
- Cryotherapy with liquid nitrogen is used in dermatology for treatment of actinic keratoses, benign keratoses, and other superficial lesions. Post-cryotherapy wound progression is predictable: erythema and edema within minutes of treatment, blister formation within 24 to 48 hours, blister rupture and crusting by day 3 to 5, and re-epithelialization within 7 to 14 days depending on treatment depth and anatomic location. Discharge instructions must describe this progression so patients do not present to urgent care because of blistering they interpret as a complication. Instructions should specify: what a normal blister looks like after cryotherapy, that the blister should be left intact if possible, how to care for the area after blister rupture (keep moist with petrolatum), and when to call the office if the site is not healed within the expected timeframe.
- Shave and punch biopsy aftercare instructions must specify the wound care regimen specific to the biopsy type. A shave biopsy site is an open wound that heals by second intention over 7 to 14 days with petrolatum-based wound care; a punch biopsy site may be sutured or left open depending on the provider's preference and the wound size. Instructions should specify: whether sutures are present and if so, the suture removal timeline, wound care steps by frequency, signs of infection to watch for, and pathology follow-up instructions as described above. Biopsy sites on the leg heal more slowly than sites at other locations due to venous and arterial circulatory factors, and leg biopsy patients should receive instructions that account for this extended healing timeline and include leg elevation guidance.
- Documentation of the pre-procedure discussion for any skin biopsy should include that the patient was informed of the purpose of the biopsy, the method by which results will be communicated, and the expectation that results will be available within a specified timeframe. This documentation protects the practice in situations where pathology results are significantly delayed by the laboratory or where the patient later claims they were not informed that tissue was removed for analysis. Practices performing high volumes of biopsies should have a tracking system that flags unreported pathology results at the specified follow-up window and documents the outreach attempt when results are not yet received.
