Greening Hand Surgery: Targeted Measures to Reduce Waste in Ambulatory Trigger Finger and Carpal Tunnel Decompression.

BACKGROUND: Operating rooms (ORs) produce approximately 70% of hospital waste. Greening strategies in the OR aim to reduce the environmental impact of surgery while maintaining patient safety and outcomes. The aim of this study was to strategically reduce waste and cost associated with common ambulatory hand procedures by implementing a 3-stage "green case" plan over a 1-year period in a high-volume tertiary referral hand surgery division. METHODS: A 3-stage greening initiative for hand surgery was designed and implemented in ambulatory open carpal tunnel release (CTR) and trigger finger release (TFR) cases, including: (1) introduction of minor field sterility; (2) implementation of a lean and green minor hand surgery pack and reduced instrument set; and (3) elimination of gown use by surgeons and OR staff. Surgical supply usage and costs were tracked during the study period and compared with control. RESULTS: Each "green case" resulted in savings of $105 compared with the control cases from the preceding year, excluding cost savings associated with reduced waste processing. There was a 64% and 75% reduction in waste and costs after greening, respectively. This equates to a minimum institutional annual savings of $51 000 when used for CTR and TFR. There was no observed increase in surgical site infections or complications after the introduction of greening. CONCLUSION: Greening initiatives can be successfully implemented by surgeons to reduce waste and costs. With targeted greening of CTR and TFR procedures, we significantly reduced waste and decreased costs while maintaining patient safety and outcomes.

Investigating the Efficacy of Modified Lipoaspirate Grafting to Improve the Appearance of Atrophic Acne Scars: A Pilot Study.

BACKGROUND: Processed lipoaspirate grafting describes several techniques theorized to leverage the inflammatory and regenerative capacities of mechanically processed adipocytes to rejuvenate and correct skin pathology. Although lipoaspirate grafting is typically leveraged to fill visible defects such as depressed scars and dermal lines, additional fat processing allows grafts to stimulate mechanisms of wound healing, including the promotion of fibroblast activation, neovascularization, and neocollagenesis. OBJECTIVES: This study intends to assess the efficacy and tolerability of processed lipoaspirate grafting monotherapy to improve the clinical appearance of atrophic acne scars. METHODS: Patients underwent a single autologous processed lipoaspirate grafting procedure at the site of atrophic acne scars. Objective and subjective scar analysis was performed at 3 and 6 months posttreatment. Scars were assessed with standard photography, topographic analysis, and noninvasive skin measurements. In addition, microbiopsies were obtained before and after treatment to assess histological or genetic changes. Clinical improvement was assessed with patient and clinician Global Aesthetic Improvement Scales (GAIS) and blinded photographic evaluation. RESULTS: Ten patients between ages 18 and 60 completed the study. Clinical evaluation demonstrated that fat grafting improved the appearance of atrophic acne scars. Clinician GAIS and patient GAIS scores showed clinical improvement at both 3- and 6-month follow-up compared with baseline (P < .05). Blinded clinician GAIS scores also showed statistically significant improvement when clinicians compared clinical photographs taken at 6-month follow-up to baseline (P < .0001). The attenuation coefficient increased at 6-month follow-up, suggesting collagen remodeling and reorganization over the study period. Patients experienced anticipated posttreatment symptoms including transient erythema and edema; however, no unexpected adverse events were reported. CONCLUSIONS: Micronized lipoaspirate injection is a viable and effective option to improve the appearance of facial acne scarring. Favorable improvements in atrophic acne scarring were captured by objective analysis of skin ultrastructure as well as improvement in subjective assessments of scarring.

Investigating the efficacy of a fractionated 1927 nm laser for diffuse dyspigmentation and actinic changes.

OBJECTIVES: Facial actinic irregularities are frequent targets for noninvasive, energy-based treatment. These irregularities are multifactorial and driven by both intrinsic factors such as aging, genetics, and hormone exposure, and extrinsic factors, such as UV exposure. Clinically, this photodamage manifests as dyschromic skin disorders like melasma and actinic features such as solar lentigines. Fractionated 1927 nm (f1927 nm) nonablative lasers are suitable for targeting epidermal lesions and have been shown to be effective in resurfacing photoaged skin as well as addressing pigmented lesions without exacerbation. The purpose of this study was to quantify the magnitude and duration of actinic pigment and photodamage response in patients of Fitzpatrick Skin Phototypes (SPT) I-IV who underwent two treatments with a fractionated, nonablative 1927 nm thulium laser (MOXI™, Sciton). METHODS: The authors conducted an IRB-approved, single-center, prospective, nonrandomized study to evaluate the efficacy of f1927 nm nonablative lasers in the treatment of diffuse dyspigmentation and actinic irregularities. Patients underwent two treatments with f1927 nm nonablative laser at a 1-month interval. F1927 nm treatment and energy parameters included a pulse energy of 15 mJ, density of 15% with 15% coverage, and six total passes. The primary endpoint for this study was pigment response after treatment, measured using the VISIA Skin Imaging and Analysis System (Canfield Scientific). Pigmentary lesions measured and analyzed included spots, UV spots, and brown spots. The Physician's Global Assessment Scale was used by plastic surgeons to provide a subjective clinical assessment of melasma response. Nonparametric testing was used to assess and compare VISIA results across the study period as well as clinician evaluations. A p value ≤ 0.05 was considered statistically significant. RESULTS: Twenty-seven patients underwent two treatments with nonablative, f1927 nm laser in May and June 2022. Ninety-six percent of patients (n = 26) completed 1-month follow-up and 89% of patients (n = 24) completed 3-month follow-up. The study cohort was 100% female, with a mean ± SD age of 47.0 ± 11.5 (range: 29-74), and a mean Fitzpatrick SPT of 2.8 (range: I-IV). No serious adverse events were observed during study treatment or follow-up. Overall, analysis showed statistically significant improvements in dyspigmentation at 1 month and an increase in pigment toward baseline at 3 months. At 1 month, there was a statistically significant decrease in spots (p = 0.002), UV spots (p < 0.001), and brown spots (p < 0.001) compared to baseline. At 3 months, Brown spots remained significantly improved compared to baseline (p = 0.05). Analysis showed 9.9% improvement in pigment on the left (p < 0.0001) and 7.5% improvement in pigment on the right (p < 0.0001) face. Right dyspigmentation remained significantly improved at 3-month follow-up (p = 0.02). Subjectively, clinician evaluators' mean Physician's Global Assessment Scale score was 3.4 (p < 0.0001) at 1-month follow-up and 3.7 (p < 0.0001) at 3-month follow-up, which correspond to an approximately 50% improvement hyperpigmentation when at both time points. CONCLUSION: These results demonstrate that fractionated, nonablative 1927 nm laser treatment is an effective modality for improving clinical and subclinical photodamage. The magnitude and duration of pigment improvement are potentially influenced by the propensity for photodamage during the summer months, which may suggest the need for multiple f1927 nm treatments over time to maintain results.
