A video-based, flipped classroom, simulation curriculum for dermatologic surgery: A prospective, multi-institution study.

BACKGROUND: Medical education is evolving to emphasize trainee engagement. The impact of a flipped classroom curriculum and surgical simulation on dermatology resident education has not been evaluated. OBJECTIVE: To assess the impact of video education and surgical simulation on dermatology resident procedural skills. METHODS: We created a curriculum on foundational surgical skills for 31 first- and second-year dermatology residents at 3 institutions. The flipped classroom approach replaces traditional in-person lectures with at-home viewing of instructional videos. After this self-directed learning, trainees had 3 hands-on sessions using simulated skin models. The Objective Structured Assessment of Technical Skills (OSATS) instrument was used to assess residents performing a simulated elliptical excision with intermediate repair before and after the curriculum. Residents completed precurriculum and postcurriculum surveys evaluating operative confidence and perceived value of the curriculum. RESULTS: Residents' total OSATS score increased from a median of 27 (interquartile range, 22-38.5) before the curriculum to 46 (interquartile range, 39.5-51.5) after the curriculum (P < .001). Self-reported confidence in surgical performance significantly improved, and residents were highly satisfied. LIMITATIONS: Limitations include the small sample size and potential influence from concurrent learning on surgical rotations. CONCLUSIONS: Video education and simulation are effective for improving dermatology residents' procedural skills. We hope to serve as a template for other institutions and nondermatology trainees hoping to improve procedural skills.

Analysis of the effects of EHR implementation on timeliness of care in a dermatology clinic: a simulation study.

Objective: Quantify the downstream impact on patient wait times and overall length of stay due to small increases in encounter times caused by the implementation of a new electronic health record (EHR) system. Methods: A discrete-event simulation model was created to examine the effects of increasing the provider-patient encounter time by 1, 2, 5, or 10 min, due to an increase in in-room documentation as part of an EHR implementation. Simulation parameters were constructed from an analysis of 52 000 visits from a scheduling database and direct observation of 93 randomly selected patients to collect all the steps involved in an outpatient dermatology patient care visit. Results: Analysis of the simulation results demonstrates that for a clinic session with an average booking appointment length of 15 min, the addition of 1, 2, 5, and 10 min for in-room physician documentation with an EHR system would result in a 5.2 (22%), 9.8 (41%), 31.8 (136%), and 87.2 (373%) minute increase in average patient wait time, and a 6.2 (12%), 11.7 (23%), 36.7 (73%), and 96.9 (193%) minute increase in length of stay, respectively. To offset the additional 1, 2, 5, or 10 min, patient volume would need to decrease by 10%, 20%, 40%, and >50%, respectively. Conclusions: Small changes to processes, such as the addition of a few minutes of extra documentation time in the exam room, can cause significant delays in the timeliness of patient care. Simulation models can assist in quantifying the downstream effects and help analyze the impact of these operational changes.

Pseudoherpetic grover disease: report of 2 cases and review of the literature.

Two cases of a pseudoherpetic variant of Grover disease are presented. The first patient was a 60-year-old woman who had high fevers in combination with right lower lobe pneumonia. She developed an itchy papulovesicular rash on her back and upper abdomen. The second patient was a 68-year-old woman who while bedridden developed an itchy papulovesicular rash on her back. Vesiculobullous forms of dermatitis were clinically suspected in both cases, and herpetic vesicles were the lead diagnosis in one case. Pathologically, lesions from both patients revealed intraepidermal fluid-filled vesicles that at scanning magnification raised the suspicion of herpetic lesions. At higher magnification, acantholytic cells, some seemingly multinucleated, could be ppreciated. However, immunohistochemistry for herpes simplex virus and varicella zoster virus antigens proved negative. Moreover, some of the lesional cells revealed dyskeratosis more typical of the spongiotic/vesicular variant of Grover disease, and accordingly, this diagnosis was eventually established in both patients. Recognition of the pseudoherpetic variant of spongiotic/vesicular Grover disease is important in determining correct treatment, and therefore, subtle clues to its diagnosis should be sought in evaluation of such lesions.

Pityriasis rubra pilaris exacerbation with topical use of imiquimod.

The role of immune response modifiers is increasing in the treatment of dermatologic diseases. Imiquimod, a toll-like receptor agonist, results in up-regulation of proinflammatory cytokines for improved immune surveillance. Although topical use is generally well-tolerated, imiquimod can potentially result in systemic effects and exacerbate generalized inflammatory papulosquamous diseases of the skin. We report the case of a 67-year-old man who was treated with imiquimod for actinic keratosis and developed fever and a progressive erythematous papulosquamous eruption that was histologically consistent with pityriasis rubra pilaris.

Transient myeloproliferative disorder causing a vesiculopustular eruption in a phenotypically normal neonate.

We report an unusual congenital vesiculopustular eruption arising in a neonate as the result of the transient myeloproliferative disorder (TMD) associated with trisomy 21. In this instance, the neonate was phenotypically normal, making the diagnosis more elusive. Initially the lesions were clinically suspicious for herpetic infection. The clinical scenario quickly became highly suggestive of leukemia cutis, given the infant's extremely high white blood cell count. Further examination revealed trisomy 21 in the leukemic cells and disomy 21 in the buccal keratinocytes, and a diagnosis of self-resolving TMD was made. Biopsy specimens of the lesions showed a sparse, perivascular, atypical, mononuclear infiltrate. We suggest that examination for a TMD be undertaken in neonates with a vesiculopustular eruption and leukemic white blood cell counts.
