Charting the course for improved outcomes in chronic critical illness: therapeutic strategies for persistent inflammation, immunosuppression, and catabolism syndrome (PICS).

Enhanced critical care delivery has led to improved survival rates in critically ill patients, yet sepsis remains a leading cause of multiorgan failure with variable recovery outcomes. Chronic critical illness, characterised by prolonged ICU stays and persistent end-organ dysfunction, presents a significant challenge in patient management, often requiring multifaceted interventions. Recent research, highlighted in a comprehensive review in the British Journal of Anaesthesia, focuses on addressing the pathophysiological drivers of chronic critical illness, such as persistent inflammation, immunosuppression, and catabolism, through targeted therapeutic strategies including immunomodulation, muscle wasting prevention, nutritional support, and microbiome modulation. Although promising avenues exist, challenges remain in patient heterogeneity, treatment timing, and the need for multimodal approaches.

Disparities in insurance status negatively affect patients with infantile hypertrophic pyloric stenosis.

PURPOSE: Infantile hypertrophic pyloric stenosis (IHPS) is suspected to have worse outcomes when length of illness prior to presentation is prolonged. Our objective was to evaluate how social determinants of health influence medical care and outcomes for babies with IHPS. METHODS: A retrospective review was performed over 10 years. Census data were used as proxy for socioeconomic status via Geo-Identification codes and correlated with food access and social vulnerability variables. The cohort was subdivided to understand the impact of Medicaid Managed Care (MMC). RESULTS: The cohort (279 cases) was divided into two groups; early group from 2011 to 2015 and late from 2016 to 2021. Cases in the late group were older at the time of presentation (41.5 vs. 36.5 days; p = 0.022) and presented later in the disease course (12.8 vs. 8.9 days; p = 0.021). There was no difference in race (p = 0.282), gender (p = 0.874), or length of stay. CONCLUSIONS: Patients who presented with IHPS after implementation of phased MMC were older, had a longer symptomatic course, and shorter pylorus measurements. Patients with public insurance after the implementation of MMC were more likely to follow-up with an outpatient pediatrician within a month of hospitalization. These results suggest that MMC may have improved access to care for infants with IHPS.

Golf cart injuries have similar severity to all-terrain vehicle injuries in children: a multicenter comparison over a 5-year period.

Background: Golf carts (GCs) and all-terrain vehicles (ATVs) are popular forms of personal transport. Although ATVs are considered adventurous and dangerous, GCs are perceived to be safer. Anecdotal experience suggests increasing numbers of both GC and ATV injuries, as well as high severity of GC injuries in children. This multicenter study examined GC and ATV injuries and compared their injury patterns, resource utilization, and outcomes. Methods: Pediatric trauma centers in Florida submitted trauma registry patients age <16 years from January 2016 to June 2021. Patients with GC or ATV mechanisms were identified. Temporal trends were evaluated. Injury patterns, resource utilization, and outcomes for GCs and ATVs were compared. Intensive care unit admission and immediate surgery needs were compared using multivariable logistic regression. Results: We identified 179 GC and 496 ATV injuries from 10 trauma centers. GC and ATV injuries both increased during the study period (R2 0.4286, 0.5946, respectively). GC patients were younger (median 11 vs 12 years, p=0.003) and had more intracranial injuries (34% vs 19%, p<0.0001). Overall Injury Severity Score (5 vs 5, p=0.27), intensive care unit (ICU) admission (20% vs 16%, p=0.24), immediate surgery (11% vs 11%, p=0.96), and mortality (1.7% vs 1.4%, p=0.72) were similar for GCs and ATVs, respectively. The risk of ICU admission (OR 1.19, 95% CI 0.74 to 1.93, p=0.47) and immediate surgery (OR 1.04, 95% CI 0.58 to 1.84, p=0.90) remained similar on multivariable logistic regression. Conclusions: During the study period, GC and ATV injuries increased. Despite their innocuous perception, GCs had a similar injury burden to ATVs. Heightened safety measures for GCs should be considered. Level of evidence: III, prognostic/epidemiological.

Transcriptomic Differences in Peripheral Monocyte Populations in Septic Patients Based on Outcome.

ABSTRACT: Post-sepsis early mortality is being replaced by survivors who experience either a rapid recovery and favorable hospital discharge or the development of chronic critical illness (CCI) with suboptimal outcomes. The underlying immunological response that determines these clinical trajectories remains poorly defined at the transcriptomic level. As classical and non-classical monocytes are key leukocytes in both the innate and adaptive immune systems, we sought to delineate the transcriptomic response of these cell types. Using single-cell RNA sequencing and pathway analyses, we identified gene expression patterns between these two groups that are consistent with differences in TNFα production based on clinical outcome. This may provide therapeutic targets for those at risk for CCI in order to improve their phenotype/endotype, morbidity, and long-term mortality.

The post-septic peripheral myeloid compartment reveals unexpected diversity in myeloid-derived suppressor cells.

Introduction: Sepsis engenders distinct host immunologic changes that include the expansion of myeloid-derived suppressor cells (MDSCs). These cells play a physiologic role in tempering acute inflammatory responses but can persist in patients who develop chronic critical illness. Methods: Cellular Indexing of Transcriptomes and Epitopes by Sequencing and transcriptomic analysis are used to describe MDSC subpopulations based on differential gene expression, RNA velocities, and biologic process clustering. Results: We identify a unique lineage and differentiation pathway for MDSCs after sepsis and describe a novel MDSC subpopulation. Additionally, we report that the heterogeneous response of the myeloid compartment of blood to sepsis is dependent on clinical outcome. Discussion: The origins and lineage of these MDSC subpopulations were previously assumed to be discrete and unidirectional; however, these cells exhibit a dynamic phenotype with considerable plasticity.

Social determinants of health in pediatric trauma: Associations with injury mechanisms and outcomes in the context of the COVID-19 pandemic.

BACKGROUND: Relationships between social determinants of health and pediatric trauma mechanisms and outcomes are unclear in context of COVID-19. METHODS: Children <16 years old injured between 2016 and 2021 from ten pediatric trauma centers in Florida were included. Patients were stratified by high vs. low Social Vulnerability Index (SVI). Injury mechanisms studied were child abuse, ATV/golf carts, and firearms. Mechanism incidence trends and mortality were evaluated by interrupted time series and multivariable logistic regression. RESULTS: Of 19,319 children, 68% and 32% had high and low SVI, respectively. Child abuse increased across SVI strata and did not change with COVID. ATV/golf cart injuries increased after COVID among children with low SVI. Firearm injuries increased after COVID among children with high SVI. Mortality was predicted by injury mechanism, but was not independently associated with SVI, race, or COVID. CONCLUSION: Social vulnerability influences pediatric trauma mechanisms and COVID effects. Child abuse and firearm injuries should be targeted for prevention.

Monocyte anisocytosis corresponds with increasing severity of COVID-19 in children.

Introduction: Although SARS-CoV-2 infection can lead to severe COVID-19 in children, the role of biomarkers for assessing the risk of progression to severe disease is not well established in the pediatric population. Given the differences in monocyte signatures associated with worsening COVID-19 in adults, we aimed to determine whether monocyte anisocytosis early in the infectious course would correspond with increasing severity of COVID-19 in children. Methods: We performed a multicenter retrospective study of 215 children with SARS-CoV-2 infection, Multisystem Inflammatory Syndrome in Children (MIS-C), convalescent COVID-19, and healthy age-matched controls to determine whether monocyte anisocytosis, quantified by monocyte distribution width (MDW) on complete blood count, was associated with increasing severity of COVID-19. We performed exploratory analyses to identify other hematologic parameters in the inflammatory signature of pediatric SARS-CoV-2 infection and determine the most effective combination of markers for assessing COVID-19 severity in children. Results: Monocyte anisocytosis increases with COVID-19 severity and need for hospitalization. Although other inflammatory markers such as lymphocyte count, neutrophil/lymphocyte ratio, C-reactive protein, and cytokines correlate with disease severity, these parameters were not as sensitive as MDW for identifying severe disease in children. An MDW threshold of 23 offers a sensitive marker for severe pediatric COVID-19, with improved accuracy when assessed in combination with other hematologic parameters. Conclusion: Monocyte anisocytosis corresponds with shifting hematologic profiles and inflammatory markers in children with COVID-19, and MDW serves as a clinically accessible biomarker for severe COVID-19 in children.

VARIABLES INFLUENCING THE DIFFERENTIAL HOST RESPONSE TO BURNS IN PEDIATRIC AND ADULT PATIENTS.

ABSTRACT: Burn injury is a significant source of morbidity and mortality in the pediatric population. Although 40,000 pediatric patients in the United States are admitted to the hospital with burn wounds annually, significant differences exist in the management and treatment of these patients, even among highly specialized burn centers. Some aspects of pediatric burn research, such as metabolic changes and nutritional support after burn injury, have been studied extensively; however, in many aspects of burn care, pediatric research lags behind the study of adult populations. This review compares and contrasts a wide array of physiologic and immune responses between children and adults after burn injury. Such a review elucidates where robust research has been conducted, where adult research is applicable to pediatric patients, and where additional pediatric burn research needs to be conducted.

TRAINED IMMUNITY: A POTENTIAL APPROACH FOR IMPROVING HOST IMMUNITY IN NEONATAL SEPSIS.

ABSTRACT: Sepsis, a dysregulated host immune response to infection, is one of the leading causes of neonatal mortality worldwide. Improved understanding of the perinatal immune system is critical to improve therapies to both term and preterm neonates at increased risk of sepsis. Our narrative outlines the known and unknown aspects of the human immune system through both the immune tolerant in utero period and the rapidly changing antigen-rich period after birth. We will highlight the key differences in innate and adaptive immunity noted through these developmental stages and how the unique immune phenotype in early life contributes to the elevated risk of overwhelming infection and dysregulated immune responses to infection upon exposure to external antigens shortly after birth. Given an initial dependence on neonatal innate immune host responses, we will discuss the concept of innate immune memory, or "trained immunity," and describe several potential immune modulators, which show promise in altering the dysregulated immune response in newborns and improving resilience to sepsis.

Exploring Limited English Proficiency in the Clinical Outcomes of Pediatric Burn Patients.

INTRODUCTION: Limited English proficiency (LEP) is linked to lower health care access and worse clinical outcomes. This study aims to explore the potential role of LEP on clinical outcomes of pediatric burn patients. METHODS: We conducted a single-institution retrospective study of burn patients presenting at a tertiary pediatric burn referral program between January 2016 and December 2020. Patient demographics, burn mechanism, severity, interventions, and primary patient language were abstracted from the electronic health record. Clinical outcomes (length of stay [LOS], clinic follow-up, and 30-day readmission) of patients with LEP were compared to patients with English as primary language (EPL). RESULTS: Thirty-five (4.2%) patients with LEP were identified of 840 total patients. On univariate analysis, there was no difference in mean total body surface area (6.5% versus 6.1%), report of physical abuse (2.9% versus 8.9%), or need for grafting (14.3% versus 15.0%) comparing patients with LEP to those with EPL. Patients with LEP were more likely to have a scald burn (68.6% versus 48.9%, P = 0.025) and less likely to have a flame/fire burn (20.0% versus 37.6%, P = 0.047). On multivariate analysis, there was no difference between patients with LEP compared to patients with EPL for LOS (2.9 versus 3.5 d), 30-day readmissions (5.6% versus 5.7%), or clinic follow-up (80.6% versus 75.0%). In patients with >10% total body surface area, patients with LEP had a longer emergency department LOS (277 min versus 145 min, P = 0.06) but no difference in outcome measures. CONCLUSIONS: Pediatric patients with LEP were not found to have worse burn outcomes compared to EPL patients in our patient sample. However, a true association is difficult to determine given the small sample size of LEP patients and the potential underestimation of language discordancy as recorded in the electronic medical record. Further research is needed to better explore the role of primary language and health communication as a social determinant of health in pediatric burn patients.

Structural evaluation of child physical abuse in trauma: Social determinants of health at the population level.

PURPOSE: Child physical abuse (CPA) is closely linked to social factors like insurance status with limited evaluation at a structural population-level. This study evaluates the role of social determinants of health within the built environment on CPA. METHODS: A single-institution retrospective review of pediatric trauma patients was conducted between January 2016 and December 2020. Patient address was geocoded to the census-tract level. Socioeconomic metrics, including poverty rate, supermarket access and Social Vulnerability Index (SVI) were estimated from the Food Access Research Atlas. Univariate and multivariable regression analyses were conducted to compare demographics and outcomes. RESULTS: Of 3,540 patients, 317 (9.0%) had concern for physical abuse reported in the registry. CPA patients were younger (7.5 vs 9.6 years, p<0.0001) and more often Black (37.0%, N = 117 vs 23.5%, N = 753; p<0.0001). CPA had higher injury severity scores (ISS) (7.9 vs 5.8, p<0.0001) and longer length of stay (5.3 vs 2.9 days, p<0.0001). CPA had higher Medicaid (73.0%, N = 232 vs 53.8%, N = 1748, p<0.0001) and SVI (0.65 vs 0.59, p<0.0001) with lower median income ($52,100 vs $56,100, p<0.0001) and more low-food access tracts (59.6% vs 53.6%, p = 0.06). Combined low-income and low-food access populations showed widened disparities (40.0% vs 28.9%, p = 0.0002). On multivariate analysis, CPA was associated with poverty (OR 2.3, 95% CI [0.979, 3.60], p = 0.0006), low-access Black share (OR 3.3, 95% CI [1.18, 5.47], p = 0.002) and urban designation (OR 1.5, 95% CI [1.13, 1.87], p = 0.004). CONCLUSION: The built-environment and population-level social determinants of health are related to child physical abuse and should influence advocacy and prevention. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective.

Social determinants of health in pediatric scald burns: Is food access an issue?

BACKGROUND: Burn injury risk, severity, and outcomes have been associated with socioeconomic status. Limited data exist to evaluate health access-related influences at a structural population level. This study evaluated factors at the Census-tract level, specifically evaluating food access and social vulnerability in pediatric scald burns. METHODS: A single-institution retrospective review using the trauma registry and electronic medical record was conducted of pediatric burns between 2016 and 2020. Home address was coded to the Census-tract level and bulk analyzed. Socioeconomic metrics of the home environment were evaluated from publicly available databases, the United States Food and Drug Administration Food Access Research Atlas, and the Centers for Disease Control's Social Vulnerability Index. RESULTS: There were 840 patients that met inclusion criteria (49.8% scald, N = 418). The mean total body surface area for scalds was 6.6% with an age of 10.2 years; 76% (n = 317) of scalds had Medicaid, and 15% (n = 63) were due to hot noodles. Scalds occurred more in females (45.7%, N = 191 vs 28.0%, N = 118; P < .0001), non-White race (62.7%, N = 262 vs 29.1%, N = 123; P < .0001), and low-income and low-food access populations (39.8%, N = 147 vs 30.4%, N = 116; P = .007). Low-food access Black populations showed increased scald injury (18% [interquartile range 6-35] vs 10% [interquartile range 4-25]), whereas all other populations showed no association. The patients with scalds had a higher overall social vulnerability index (0.67 vs 0.62, P = .008). CONCLUSION: Often related to poverty, health access, and health equity, population-level social determinants of health like social vulnerability and food access have significant impact on health care and should influence health outreach and systems improvement.

Heterogeneity in the evaluation of suspected MIS-C: a cross-sectional vignette-based survey.

BACKGROUND AND OBJECTIVES: Multisystem Inflammatory Syndrome in Children (MIS-C) is an emerging complication of COVID-19 which lacks a definitive diagnostic test and evidence-based guidelines for workup. We sought to assess practitioners' preferences when initiating a workup for pediatric patients presenting with symptoms concerning for MIS-C. METHODS: In a cross-sectional vignette-based survey, providers were presented with clinical vignettes of a patient presenting with 24 h of fever from a community with high rates of COVID-19. Respondents were asked about their general practices in pursuing a workup for potential MIS-C including testing obtained, criteria for diagnosis, and timing to confirm or rule out the diagnosis. RESULTS: Most of the 174 respondents were physicians from the United States at academic medical centers. The majority of providers would not initiate MIS-C workup for fever and non-specific symptoms unless the fever lasted more than 72 h. Skin rash, abdominal pain, and shortness of breath were symptoms that raised greatest concern for MIS-C. Most providers would obtain COVID-19 PCR or antigen testing, plus blood work, in the initial workup. The list of laboratory studies providers would obtain is extensive. Providers primarily rely on cardiac involvement to confirm a MIS-C diagnosis, and establishing a diagnosis takes 24-48 h. CONCLUSIONS: Significant heterogeneity exists amongst providers as to when to initiate the MIS-C workup, the order and content of the workup, and how to definitively diagnose MIS-C. A diagnostic test with high sensitivity and specificity for MIS-C and refined evidence-based guidelines are needed to expedite diagnosis and treatment.

Monocyte anisocytosis increases during multisystem inflammatory syndrome in children with cardiovascular complications.

BACKGROUND: Multisystem inflammatory syndrome in children (MIS-C) is a life-threatening complication that can develop weeks to months after an initial SARS-CoV-2 infection. A complex, time-consuming laboratory evaluation is currently required to distinguish MIS-C from other illnesses. New assays are urgently needed early in the evaluation process to expedite MIS-C workup and initiate treatment when appropriate. This study aimed to measure the performance of a monocyte anisocytosis index, obtained on routine complete blood count (CBC), to rapidly identify subjects with MIS-C at risk for cardiac complications. METHODS: We measured monocyte anisocytosis, quantified by monocyte distribution width (MDW), in blood samples collected from children who sought medical care in a single medical center from April 2020 to October 2020 (discovery cohort). After identifying an effective MDW threshold associated with MIS-C, we tested the utility of MDW as a tier 1 assay for MIS-C at multiple institutions from October 2020 to October 2021 (validation cohort). The main outcome was the early screening of MIS-C, with a focus on children with MIS-C who displayed cardiac complications. The screening accuracy of MDW was compared to tier 1 routine laboratory tests recommended for evaluating a child for MIS-C. RESULTS: We enrolled 765 children and collected 846 blood samples for analysis. In the discovery cohort, monocyte anisocytosis, quantified as an MDW threshold of 24.0, had 100% sensitivity (95% CI 78-100%) and 80% specificity (95% CI 69-88%) for identifying MIS-C. In the validation cohort, an initial MDW greater than 24.0 maintained a 100% sensitivity (95% CI 80-100%) and monocyte anisocytosis displayed a diagnostic accuracy greater that other clinically available hematologic parameters. Monocyte anisocytosis decreased with disease resolution to values equivalent to those of healthy controls. CONCLUSIONS: Monocyte anisocytosis detected by CBC early in the clinical workup improves the identification of children with MIS-C with cardiac complications, thereby creating opportunities for improving current practice guidelines.

T-Cell Activation and LPS: A Dangerous Duo for Organ Dysfunction.

Lipopolysaccharide (LPS), one of the main components of cell membranes in gram-negative bacteria, is commonly used to promote inflammation-induced organ dysfunction. In the TLR4/LPS pathway, LPS binding protein and CD14 enable lipid A of LPS to be recognized by the TLR4-MD2 receptor complex. The intracellular domain of the TLR4/LPS complex stimulates MyD88-dependent/independent and TRIF-dependent pathways, which in turn activate NF-B and IRF3, leading to subsequent production of pro-inflammatory mediators. LPS has been demonstrated to induce microcirculatory disturbances via promotion of leukocyte adhesion to the vascular endothelium and the release of reactive oxygen species (ROS), damaging the vessels and causing vascular dysfunction. Thus, LPS is frequently used as a systemic model of inflammation as LPS administration increases circulating pro-inflammatory mediators, which triggers leukocyte adhesion and leads to multi-organ failure and death.

Medical Student Career Choice: Who Is the Influencer?

BACKGROUND: While many factors influence medical student career choice, interactions with attending and resident physicians during clinical rotations are particularly important. To evaluate the influence of attending and resident physicians on medical students' career choices, particularly for those pursuing surgical careers, we quantified their respective influence in the context of other known influences. METHODS: Rising fourth-year medical students and new graduates were given an IRB-exempt, 14-item online survey. Descriptive statistics were performed on the demographic information. Chi-square analysis was used, as were Kruskal-Wallis and Mann-Whitney analyses on the Likert responses (α = 0.05). RESULTS: Survey response was 24%. Students pursuing general surgery rated residents greater than or equal to attendings on 7 of 8 key mentoring characteristics. Of students choosing a different specialty than the one they intended to pursue upon entering medical school, the influence of residents was cited by 100% of the students pursuing general surgery, compared to 59% of the entire cohort. Identification of a role model and perceived personality fit were significantly more important than other factors (P < 0.0001). Students pursuing general surgery rated the importance of identifying a role model and perceived personality fit greater than their peers. CONCLUSIONS: Residents have greater influences on medical students' career choice compared to attendings. Students pursuing a surgical specialty, particularly general surgery, considered the influence of role models and perceived personality fit to be the most important factors in their specialty decision. These findings provide valuable insights to improve student experiences and career recruitment in surgical specialties, particularly general surgery.

Cecal Slurry Injection in Neonatal and Adult Mice.

Studying the pathophysiology of sepsis still requires animal models, and the mouse remains the most commonly used species. Here we discuss the "cecal slurry" (CS) model of polymicrobial, peritoneal sepsis and compare and contrast it to other commonly used methods. Among the different murine models of sepsis, cecal ligation and puncture (CLP), and not the CS, is often considered the "gold standard" to induce polymicrobial sepsis in laboratory animals. CLP is a well-described model involving a simple surgical procedure that closely mimics the clinical course of intra-abdominal sepsis. However, CLP may not be an option for experiments involving newborn pups, where the cecum is indistinguishable from small bowel, where differences in microbiome content may affect the experiment, or where surgical procedures/anesthesia exposure needs to be limited. An important alternative method is the CS model, involving the intraperitoneal injection of cecal contents from a donor animal into the peritoneal cavity of a recipient animal to induce polymicrobial sepsis. Furthermore, CS is an effective alternative model of intraperitoneal polymicrobial sepsis in adult mice and can now be considered the "gold standard" for experiments in neonatal mice.

Prehospital personnel discretion pediatric trauma team activations: Too much of a good thing?

PURPOSE: Trauma team activation is essential to provide rapid assessment of injured patients, however excessive utilization can overburden systems. We aimed to identify predictors of over triage and evaluate impact of prehospital personal discretion trauma activations on the over triage rate. METHODS: Retrospective comparative study of pediatric trauma patients (<18 years) evaluated after activation of the trauma team to those evaluated as a trauma consult treated between 2010 and 2013. Cohort matching of trauma activated and consult patients was done on the basis of patients' age and ISS. RESULTS: 1363 patients including 359 trauma team activations were evaluated. Median age was 6 years, Injury Severity Score (ISS) 4, 116 (8.5%) required operative intervention and 20 (1.4%) died. Matched analysis using age and ISS showed trauma activated patients were more likely to have penetrating MOI (4.7% vs.1.7%; p = 0.03) and need ICU admission(32.9% vs.16.7%; p = 0.0001). State of Florida discrete criteria based trauma activated patients when compared to paramedic discretion activations had a higher ISS (9 vs.5; p = 0.014), need for ICU admission (36.5% vs.20.4%; p = 0.004), ICU LOS(2 vs.0 days; p = 0.02), hospital LOS(2 vs.2 days; p = 0.014) and higher likelihood of death(4.9% vs.0%;p = 0.0001). Moreover, paramedic discretion trauma activated patients were similar to trauma consult patients in terms of ISS score(p = 0.86), need for ICU admission(p = 0.86), operative intervention(p = 0.86), death(p = 0.86) and hospital LOS(p = 0.86), with a considerably higher cost of care(p = 0.0002). CONCLUSION: Discrete criteria-based trauma team activations appear to more reliably identify patients likely to benefit from initial multidisciplinary management.

Analysis of Outcomes in Adolescents and Young Adults With Pilonidal Disease.

Purpose: Numerous definitive surgical techniques exist for the treatment of pilonidal disease with varied recurrence rates and wound complications. Due to the wide array of techniques and lack of consensus on the best approach, we proposed to study our experience treating pilonidal disease in adolescents and young adults. Methods: A retrospective analysis was conducted of patients 10-24 years old treated at a tertiary medical center from 2011 to 2016. Data including demographics, management, and outcomes were collected and analyzed. Primary outcome was recurrence of disease. Results: One hundred and thirty three patients with pilonidal disease underwent operative management. Fifty one percent underwent primary closure and 49% healed by secondary intention with no significant difference in recurrence rates (primary 18%, secondary 11%; p = 0.3245). Secondary healing patients had significantly lower wound complication rates (primary 51%, secondary 23%; p = 0.0012). After accounting for sex, race, weight, and operative technique, age was predictive of disease recurrence with an adjusted odds ratio (OR) of 0.706 (0.560-0.888; p = 0.003). Age and sex were both predictive of wound complications. Older patients had decreased risk of wound complication (adjusted OR 0.806, 95% CI 0.684-0.951; p = 0.0105), and male patients had increased risk of wound complication (adjusted OR 2.902, 95% CI 1.001-8.409; p = 0.0497). Conclusion: In summary, there is no significant difference in the recurrence rates between operative techniques for pilonidal disease. Older patients have decreased risk of recurrence following intervention. Wound complication rates are lower in patients undergoing secondary healing, though this may be better explained by differences in age and sex. Additional research investigating newer, minimally-invasive techniques needs to be pursued.
