The physician experience of patient to provider prejudice (PPtP).

Background: Patients can demonstrate prejudice and bias toward minoritized physicians in a destructive dynamic identified as PPtP (Patient Prejudice toward Providers). These interactions have a negative impact on the physical and mental well-being of both those who are targeted and those who witness such behaviors. Study purpose: The purpose of this study was to explore the PPtP experiences of attending physicians who identify as a minority based on race, ethnicity, citizenship status, or faith preference. Methods: Qualitative methodology was used to collect data using in-depth interviews. 15 attending physicians (8 male, 7 female, aged 33-55 years) who identified as minorities based on ethnicity, citizenship status, or faith practices were interviewed individually. Interviews were conducted using a guide validated in previous studies and content analysis was performed by two trained researchers to identify themes. Results: Five themes were identified: A Continuum of Offenses, Professional Growth through Adversity, Organizational Issues, Role of Colleagues, and Consequences for Provision of Care. Findings suggest that although attending physicians learned to cope with PPtP, the experience of being treated with bias negatively impacted their well-being and work performance. Attending physicians also felt that white majority medical students sometimes treated them with prejudice but expressed a commitment to protecting vulnerable trainees from PPtP. Conclusion: The experience of PPtP occurs consistently throughout a career in medicine, often beginning in the years of training and persisting into the phase of attending status. This makes it imperative to include strategies that address PPtP in order to successfully recruit and retain minoritized physicians.

Vascular persistence following precision micropuncture.

OBJECTIVE: The success of engineered tissues continues to be limited by time to vascularization and perfusion. Recently, we described a simple microsurgical approach, termed micropuncture (MP), which could be used to rapidly vascularize an adjacently placed scaffold from the recipient macrovasculature. Here we studied the long-term persistence of the MP-induced microvasculature. METHODS: Segmental 60 µm diameter MPs were created in the recipient rat femoral artery and vein followed by coverage with a simple Type 1 collagen scaffold. The recipient vasculature and scaffold were then wrapped en bloc with a silicone sheet to isolate intrinsic vascularization. Scaffolds were harvested at 28 days post-implantation for detailed analysis, including using a novel artificial intelligence (AI) approach. RESULTS: MP scaffolds demonstrated a sustained increase of vascular density compared to internal non-MP control scaffolds (p < 0.05) secondary to increases in both vessel diameters (p < 0.05) and branch counts (p < 0.05). MP scaffolds also demonstrated statistically significant increases in red blood cell (RBC) perfused lumens. CONCLUSIONS: This study further highlights that the intrinsic MP-induced vasculature continues to persist long-term. Its combination of rapid and stable angiogenesis represents a novel surgical platform for engineered scaffold and graft perfusion.

Uncovering a Failed Pediatric Patient Population in Rural America: A Statewide Analysis of Over 1,000 Dog Bite Injuries.

Pediatric dog bites are prevalent and often devastating. Population-based data on these injuries can aid public health intervention efforts. However, most existing literature comes from single institutions in urban settings. We assess a statewide cohort to compare injury characteristics in urban and rural regions and find predictors for inter-hospital transfer. Data from 1,007 injuries from 2000 to 2015 were analyzed. Patients in rural areas were younger, more likely to be white and low-income, and more likely to receive delayed patient care. Injuries occurring in public settings as opposed to the private residence were more likely to involve males, occur in low-income areas, and involve non-white patients. Patients who required inter-hospital transfer were more likely to require a surgical subspecialist and operative repair. Our population analysis reveals children living in rural areas as a previously unidentified vulnerable patient population that may be suitable targets for public health interventions.

Head and Neck Free Flap Reconstruction in an Academic versus a Community Setting.

BACKGROUND: Head and neck free flap reconstructions are complex procedures requiring extensive resources, and have the potential to be highly morbid. As such, it is imperative that they should be performed in an appropriate setting, optimizing outcomes while limiting morbidity. The aim of this study is to identify any disparities in the treatment outcomes of patients undergoing head and neck free flap reconstruction by a single surgeon in an academic versus a community hospital setting. METHODS: A retrospective review of all patients who underwent head and neck free flap reconstruction for any indication by a single surgeon from 2009 to 2019 was conducted. All surgeries were performed at one of two hospitals: one academic medical center and one community hospital. Demographics and rates of partial or complete flap failure, medical complications, surgical complications, mortality, and other secondary outcomes were compared between the two settings. RESULTS: Ninety-two patients who underwent head and neck free flap reconstruction were included. Fifty-seven (62%) of free flap reconstructions were performed in the academic medical center, while 35 (38%) were performed in the community hospital. There were no significant differences in complete flap loss, either intraoperative or postoperative (p = 0.5060), partial flap loss (p = 0.5827), postoperative surgical complications (p = 0.2930), or medical complications (p = 0.7960) between groups. The in-hospital mortality rate was 0% (n = 0) at the university hospital as compared with 5.7% at the community hospital (p = 0.0681). The mean operative time was 702.3 minutes at the university hospital and 606.3 minutes at the community hospital (p = 0.0080). CONCLUSION: Head and neck free flap surgery can be performed safely in either an academic or a community setting, with no difference in primary outcomes of surgery. Preferential selection of either treatment setting should be based on consideration of patient needs and availability of auxiliary specialty services.

Proper preservation of amputated parts: A multi-level shortcoming.

BACKGROUND: Successful replantation relies on proper preservation of traumatically amputated parts. The established protocol for preservation, however, is inconsistently adhered to. The objective of this study is to examine the rate of proper preservation in multiple patient populations. METHODS: A retrospective review of patients from 2015 to 2019 at a single academic institution was conducted. Patients were included if they suffered a traumatic amputation, the amputated part was present for evaluation by the hand surgery team, and modality of preservation was documented. Additional data including method of patient transport, replantation attempt, and operative outcome were assessed. Patients were stratified based on whether proper preservation was employed and compared using chi-square tests. RESULTS: Ninety-one patients were included, thirty-one (34.1%) of whom had amputated parts which were properly preserved. Patients from referring facilities were more likely to present with properly preserved parts (45.0%) than those presenting from home (25.5%), though this did not meet significance (P = .051). In total, 74 patients arrived via EMS with 35.1% adherence to preservation protocol. Of the 31 patients who had properly preserved parts, 58.1% underwent attempted replant; of the 60 patients who had improperly preserved parts, 23.3% underwent attempted replantation (P = .001). CONCLUSIONS: The majority of patients who suffer traumatic amputations do not present with properly preserved amputated parts, limiting potential replantation. With a direct correlation to attempted replantation, proper preservation is a crucial aspect of care and should not be overlooked when seeking to optimize efforts and results. LEVEL OF EVIDENCE: Level IV.

Emerging Therapies in the Treatment of Advanced Melanoma.

Great strides in immunotherapy and targeted therapy have revolutionized the management of previously devastating, advanced melanomas. Although these subfields continue to progress, novel approaches in intratumoral oncolytic therapy, adoptive cell therapy, and vaccine therapies are being developed as adjuncts or alternatives. Cytokines, meanwhile, are seeing a resurgence as a viable option as well. The array of effective agents will, in the next few years, provide options for therapy not only in the adjuvant or unresectable settings but also in the neoadjuvant settings. Perhaps, too, in earlier stage melanomas.

Clinical and cost efficacy of advanced wound care matrices in the treatment of venous leg ulcers: a systematic review.

BACKGROUND: Venous leg ulcers (VLUs) are hard-to-heal, recurrent and challenging to treat. Advanced wound care matrices (AWCMs) have been developed to supplement conventional therapies. These costly AWCMs warrant careful comparison as healthcare expenditures are subjected to increasing scrutiny. AIM: This study was designed to compare AWCMs in their ability to heal VLUs and their cost efficacy through a systematic review of randomised controlled trials (RCTs). METHOD: An organised search of Medline, Cochrane Library, Central and CINAHL databases identified RCTs that compared AWCMs to standard compression therapy in the healing of VLUs. Bias was assessed using the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies. Eight studies analysing bilayered skin substitute (BSS) (Apligraf), dehydrated human amnion/chorion membrane (dHACM) (Epifix), human fibroblast-derived dermal substitute (HFDDS) (Dermagraft), extracellular wound matrix (ECM) (Oasis), advanced matrix (AM) (Talymed) and matrix wound dressing (MWD) (Promogran) met the inclusion criteria. RESULTS: Four studies reported significant improvement over standard therapy: BSS, dHACM, ECM and AM. Incremental cost per additional successful treatment was determined for each trial, ranging from $2593 (MWD) to $210,800 (HFDDS). CONCLUSION: Our consolidated analysis of eight major RCTs of AWCMs in the treatment of VLUs revealed a great variation in clinical and cost efficacy among these products. The included trials were inconsistent in methodology, and these limitations should be noted, but, in the absence of RCTs to compare these products, our systematic review may serve as a guide for practitioners who seek to optimise wound healing while considering cost efficacy.

Management of Intravenous Infiltration Injuries.

BACKGROUND: Intravenous (IV) lines are ubiquitous in hospital settings. These lines can malfunction, leaking noxious contents into subcutaneous tissue. Existing literature describes invasive intervention and complex treatment protocols. These persist despite significant changes in the composition and administration of IV agents. The purpose of this study is to examine the consequences of IV infiltrations at a tertiary medical center to update protocols and treatment algorithms. MATERIALS AND METHODS: This study is an observational, retrospective chart review performed at a tertiary care medical center. All inpatient plastic surgery consultations for IV infiltration were reviewed from 2011 to 2017. Patients were included if IV infiltration was suspected or documented. Data were collected for each injury regarding patient demographics, substance, and intervention. RESULTS: The plastic surgery service evaluated 381 IV infiltration injuries from 2011 to 2017, with 363 meeting the criteria. Injuries per year progressively increased, with 32 consultations in 2011 and 102 consultations in 2017. The vast majority of injuries identified (91%) were treated with only elevation and observation. The minority consisted of wound care (7%) performed by nursing or any form of incision, aspiration, or antidote injection (2%) performed by the physician. Of the 363 injuries, the most common infiltrates were noncytotoxic (35%), radiographic contrast (27%), and known vesicants (18%). Interestingly, a large portion of consultations were requested by other surgical services (32%). CONCLUSIONS: Although there is an increase in expert involvement for cases of IV infiltration injuries, the vast majority of these injuries are managed with minimal intervention. This is most likely owing to recent changes that have decreased the potential for harmful infiltration. Contrary to existing literature, invasive intervention is almost never indicated.

A modified clinical scoring system for bladder pain syndrome: Long term experience.

PURPOSE: To document a modified clinical scoring system in patients with bladder pain syndrome that increases weightage to pain and nocturia and includes measures for sexual dysfunction and psychological impact. The clinical outcome of a set combination of treatment modalities linked to the clinical score at entry was also made. METHODS: The new proposed scale was used to assess and treat 190 enrolled patients from January 2009 to September 30, 2017. The patients were evaluated using the new scoring system at the time of induction, after 1, 3 and 6 months after commencement of treatment. Thereafter, they were followed every 6 months. The new scoring system included increased weightage to pain and nocturia and added domains of sexual dysfunction and psychological impact. The patients were treated with a protocol followed by the authors and published in the year 2007. A pictorial linkage of treatment modalities used with the clinical score of the patient was also described. RESULTS: A total of 174 evaluable patients had a follow up between 6 and 105 months (mean 64 months). The patients had age distribution between 24 and 76 years and included 19 male patients. 154 out of 174 patients (88.5%) had good or excellent response to treatment using the proposed scale at the end of 6 months. CONCLUSIONS: The proposed clinical scale appeared to aid clinical stratification of severity of the disease at the induction and during follow up. The treatment protocol could be linked with the clinical score at the time of induction.

The Omental Free Flap-A Review of Usage and Physiology.

BACKGROUND: The omental flap has a rich history of use over the last century, and specifically as a free flap in the last four decades. It has a wide variety of applications in reconstructive surgery and has shown itself to be a reliable donor tissue. We seek to review the properties that make the omental free flap a valuable tool in reconstruction, as well as its many surgical applications in all anatomic regions of the body. METHODS: We conducted a narrative review of the literature on Medline and Google Scholar. We reviewed basic science articles discussing the intrinsic properties of omental tissue, along with clinical papers describing its applications. RESULTS: The omental free flap is anatomically suitable for harvest and wound coverage and has molecular properties that promote healing and improve function at recipient sites. It has demonstrated utility in a wide variety of reconstructive procedures spanning the head and neck, extremities, and viscera and for several purposes, including wound coverage, lymphedema treatment, and vascularization. It is also occasionally employed in the thoracic cavity and chest wall, though more often as a pedicled flap. More novel uses include its use for cerebrospinal fluid leaks. CONCLUSIONS: The omental free flap is a valuable option for reconstructive efforts in nearly all anatomic regions. This is a result of its inherent anatomy and vascularity, and its angiogenic, immunogenic, and lymphatic properties.
