Factors that influence mental health of university and college students in the UK: a systematic review.

BACKGROUND: Worsening mental health of students in higher education is a public policy concern and the impact of measures to reduce transmission of COVID-19 has heightened awareness of this issue. Preventing poor mental health and supporting positive mental wellbeing needs to be based on an evidence informed understanding what factors influence the mental health of students. OBJECTIVES: To identify factors associated with mental health of students in higher education. METHODS: We undertook a systematic review of observational studies that measured factors associated with student mental wellbeing and poor mental health. Extensive searches were undertaken across five databases. We included studies undertaken in the UK and published within the last decade (2010-2020). Due to heterogeneity of factors, and diversity of outcomes used to measure wellbeing and poor mental health the findings were analysed and described narratively. FINDINGS: We included 31 studies, most of which were cross sectional in design. Those factors most strongly and consistently associated with increased risk of developing poor mental health included students with experiences of trauma in childhood, those that identify as LGBTQ and students with autism. Factors that promote wellbeing include developing strong and supportive social networks. Students who are prepared and able to adjust to the changes that moving into higher education presents also experience better mental health. Some behaviours that are associated with poor mental health include lack of engagement both with learning and leisure activities and poor mental health literacy. CONCLUSION: Improved knowledge of factors associated with poor mental health and also those that increase mental wellbeing can provide a foundation for designing strategies and specific interventions that can prevent poor mental health and ensuring targeted support is available for students at increased risk.

A population-based analysis of the presentation and outcomes of pediatric patients with osteosarcoma in Canada: a report from CYP-C.

BACKGROUND: Frequently occurring in adolescents, osteosarcoma is the most common primary malignant bone disease, with a reported 15% of patients who present with metastasis. With advances in imaging and improvements in surgical care, an updated analysis is warranted on the outcomes of pediatric patients with osteosarcoma. METHODS: We completed a retrospective review of pediatric patients who presented with osteosarcoma between 2001 and 2017, using The Cancer in Young People in Canada (CYP-C) national database. Data on 304 patients aged younger than 15 years were analyzed. RESULTS: The proportion of patients who presented with metastasis was 23.0%. The overall 5-year survival (OS) for patients who presented with metastasis was 37.4%. Overall survival and event-free survival (EFS) were lower in these patients than in patients with localized disease (hazard ratio [HR] 4.3, p < 0.0001 and HR 3.1, p < 0.0001). For patients who presented with metastatic disease, the OS for those undergoing an operative intervention was 44.1% compared with 17.6% for those who did not undergo resection (p < 0.0001). CONCLUSION: The proportion of patients who presented with metastatic osteosarcoma in our population is higher than previously reported. Overall outcomes of patients with metastatic disease have not changed. Our data reaffirm a role for surgical resection in patients with metastasis with a need to explore new treatment strategies to improve the overall prognosis of these patients.

Virtual curriculum delivery in the COVID-19 era: the pediatric surgery boot camp v2.0.

PURPOSE: We evaluated the impact of a virtual Pediatric Surgery Bootcamp curriculum on resource utilization, learner engagement, knowledge retention, and stakeholder satisfaction. METHODS: A virtual curriculum was developed around Pediatric Surgery Milestones. GlobalCastMD delivered pre-recorded and live content over a single 10-h day with a concluding social hour. Metrics of learner engagement, faculty interaction, knowledge retention, and satisfaction were collected and analyzed during and after the course. RESULTS: Of 56 PS residencies, 31 registered (55.4%; 8/8 Canadian and 23/48 US; p = 0.006), including 42 learners overall. The virtual BC budget was $15,500 (USD), 54% of the anticipated in-person course. Pre- and post-tests were administered, revealing significant knowledge improvement (48.6% [286/589] vs 66.9% [89/133] p < 0.0002). Learner surveys (n = 14) suggested the virtual BC facilitated fellowship transition (85%) and strengthened peer-group camaraderie (69%), but in-person events were still favored (77%). Program Directors (PD) were surveyed, and respondents (n = 22) also favored in-person events (61%). PDs not registering their learners (n = 7) perceived insufficient value-added and concern for excessive participants. CONCLUSIONS: The virtual bootcamp format reduced overall expenses, interfered less with schedules, achieved more inclusive reach, and facilitated content archiving. Despite these advantages, learners and program directors still favored in-person education. LEVEL OF EVIDENCE: III.

Comparing quality of life improvement after antegrade continence enema (ACE) therapy for patients with organic and functional constipation / encopresis.

BACKGROUND: We compared patient- and family-reported overall and stool-related quality of life (QoL) before and after an antegrade continence enema (ACE) procedure (cecostomy tube insertion) for refractory chronic constipation or fecal incontinence (CCFI). We hypothesized that patients with functional diagnoses experience similar improvements in QoL compared to those with organic diagnoses. METHODS: This is a cross-sectional study of patients undergoing cecostomy tube insertion for CCFI at a tertiary pediatric hospital from 2012 to 2019. Patients and/or primary caregivers completed validated stooling and overall QoL surveys based on three time points: before surgery, three months after surgery, and at the time of survey / date of last follow-up. Repeated measures analyses compared scores over time between subjects and within the diagnostic groups. RESULTS: The response rate was 65% (22/34 patients, 12 organic and 10 functional diagnoses). Mean age was 8.3 years and 32% of the participants were female. Organic diagnoses were: spina bifida (6), anorectal malformation (5), and Hirschsprung Disease (1). There was substantial improvement in stool-related and overall QoL at three months post-ACE procedure (both p<0.001) for all patients; both scores continued to improve significantly until the date of last follow-up (median 4.1 years, IQR 2.3-5.6, p<0.001). There was no statistically significant difference in scores between patients with organic and functional diagnoses. CONCLUSIONS: Caregivers perceive a significant, sustainable improvement in stooling habits and QoL following ACE therapy. The improvement is comparable between patients with a functional diagnosis and those with an underlying organic reason for their CCFI.

A survey of management preferences for bladder exstrophy and cloacal anomalies among Canadian pediatric surgeons and urologists.

PURPOSE: This study examined the current referral patterns and preferences of Canadian Association of Paediatric Surgeons (CAPS) and Pediatric Urologists of Canada (PUC) members for management of bladder exstrophy and cloacal anomalies (BECA). METHODS: We invited CAPS and PUC members to participate in an online survey using RedCap. Demographic variables, years in practice, current referral patterns and local expertise at the participants' institution were collected. Participants' preferences towards three distinct referral models were assessed using Likert scales: no centralization of care, centralization in one or two national centres of excellence, or a consortium-based approach. RESULTS: There were 82 survey respondents (2/3 were CAPS members, 35.4% female, 72% in practice for >10 years). Although >90% of participants agreed/somewhat agreed that surgical volumes impact outcomes, 58% reported not referring out BECA patients for treatment; about 50% recognized the existence of a local dedicated expert. In terms of referral preferences, 84% of participants favoured identification of a few centres with expertise based on geographic location (a consortium-based approach), while only 7% chose a one or two national centres of excellence model. Over half of participants agreed/somewhat agreed with participating in trials of a consortium-based approach in Canada. CONCLUSION: Most CAPS and PUC members do not refer BECA patients elsewhere for treatment. Nonetheless, most surgeons recognize the importance of volume to improve outcomes and show willingness to participate in trials to concentrate experience; most participants favour a consortium-based approach through identification of a few centres of excellence based on geographic location.

A comparison of balloon and nonballoon gastrostomy tubes in children.

PURPOSE: The purpose of this study was to compare primary outcomes following insertion of balloon and nonballoon gastrostomy tubes (G-tubes). METHODS: A retrospective chart review over a 5-year period comparing the need for emergency, radiologic, or operative interventions between balloon and nonballoon G-tube devices was performed. RESULTS: 145 patient charts were reviewed (46.8% female, 53.1% male). The indication for G-tube insertion was failure to thrive in 83.4%. Average age at insertion was 4.3 years (0-17.9 years). 37.2% had a balloon type G-tube, and 62.8% had a nonballoon type. Patients with a nonballoon device had 1.14 (0-15) ER visits related to the G-tube vs. 0.48 (0-6) visits with a balloon device. Of the ER visits for patients with a nonballoon device, 26.9% were replaced in ER, 38.5% in radiology, and 34.6% required an operation for replacement. For patients with a balloon device, 47.8% were replaced in the ER, 52.2% were replaced in radiology (GJ), and none required operative replacement. The majority of patients who initially had a nonballoon G-tube placed required a second operation for device change (95.7%). Patients with nonballoon devices required significantly more operations (average 2.55, range 0-16) vs patients with balloon devices (average 0.40, range 0-3) (p < .05). CONCLUSIONS: Balloon-type G-tubes require less ER visits and operative interventions compared to nonballoon G-tubes. LEVEL OF EVIDENCE: C.

A transition to discipline curriculum for pediatric surgery trainees: Evaluation of a pediatric surgery boot camp from 2017 to 2018.

INTRODUCTION: Boot camps seek to impart knowledge and skills for individuals entering new roles. We sought to evaluate knowledge, skills, and confidence of in-coming pediatric surgery trainees with a 2.5-day pediatric surgery boot camp. METHODS: A curriculum included key aspects of pediatric surgery delivered during interactive lectures, small group discussions, and simulation. With REB approval, participant demographics were collected. Pre- and posttests assessed knowledge and trainee confidence. Comparative statistics and multivariate analysis of variance (MANOVA) were performed. RESULTS: Between 2017 and 2018, 16 individuals from North American pediatric surgery training programs participated in two boot camps. Ten had North American general surgery training, and eleven had no pediatric surgery exposure ≥1 year prior. All participants expressed increased confidence with course material after boot camp [F(18,11) = 3.137;p < 0.05]. Performance improved significantly (pre- vs. posttests, 47.0% vs. 62.4%; p < 0.05). MANOVA between faculty and trainees demonstrated agreement on the value of individual sessions [F(15,3) = 0.642;p = 0.76]. Neonatal bowel obstruction, gastrostomy tube complications, esophageal atresia, pain management, and informed consent were rated most useful. CONCLUSION: Trainees and teaching faculty considered the boot camp valuable. Trainees demonstrated significant improvements in core knowledge and confidence. The initial pediatric surgery boot camp experience shows promise in facilitating the transition to discipline for new trainees. STUDY TYPE: Prospective treatment study. LEVEL OF EVIDENCE: IV.

Early, Nurse-Directed Sepsis Care.

: Background: Sepsis is one of the leading causes of hospital mortality and readmission. For the past 20 years, sepsis research has focused on best practices for treating patients with the most severe manifestations of sepsis, while the treatment of patients outside of critical care or ED settings, who have early or less severe signs and symptoms of sepsis, have received little attention. OBJECTIVE: The goal of this quality improvement (QI) initiative was to promote early recognition and treatment of sepsis through the establishment of a multidisciplinary, executive-led sepsis guiding team that leveraged nursing skills and expertise. METHODS: To meet this objective, we decided to speed the initiation of sepsis treatment at our medical center, going beyond the Surviving Sepsis Campaign guidelines in place at the time and setting as targets the identification and treatment within one hour of all inpatients and ED patients with suspected sepsis, regardless of their illness severity or care unit. Our early intervention strategy incorporated a nurse-directed ED Code Sepsis, based on the characterization of sepsis as a systemic inflammatory response syndrome-a criterion widely used at the start of this QI initiative-and an inpatient Power Hour, which authorized nurses to initiate order sets independently for lactate levels, blood cultures, and fluid boluses when they suspected sepsis. The order sets both improved bundle adherence and signaled the pharmacy to expedite antibiotic preparation and delivery. To gauge the effects of our initiative, we conducted a retrospective, interrupted time-series cohort evaluation, using the in-hospital sepsis-related mortality rate as the primary outcome, and considered as process metrics the initiation of ED Code Sepsis and the inpatient Power Hour, order set use, bundle adherence, and sepsis-related rapid response team (RRT) calls. RESULTS: Over the course of the seven-year pre- to postintervention evaluation period, ED sepsis bundle adherence increased from 40.5% to 73.7% (P < 0.001), with a mean triage to antibiotic time of 80 minutes. Sepsis-related RRT calls decreased from 2.2% to 0.85% (P < 0.001). And the in-hospital sepsis-related mortality rate dropped from 12.5% to 8.4% (P < 0.001) with an absolute reduction of 4.5 deaths per 100 sepsisrelated discharges. CONCLUSION: This project demonstrates that using nurse-directed care to promote timely identification and early treatment of sepsis in the ED and in inpatient settings can improve bundle adherence and reduce in-hospital sepsis-related mortality rates.

Effectiveness of a Multifaceted Delirium Screening, Prevention, and Treatment Initiative on the Rate of Delirium Falls in the Acute Care Setting.

Delirium is a potentially modifiable fall risk factor, but few studies address the effects of delirium programs on falls. Beginning in 2011, we implemented a nursing-driven hospitalwide delirium program targeting improvements in risk identification, prevention, detection, and treatment. Over the course of the program, delirium falls decreased from 0.91 to 0.50 per patient day (P = .0002). A decrease in overall falls was also noted (P = .0007).

Small bowel obstruction due to ingestion of rubber balls.

We report a case of a 10-month-old girl who presented with a 10-day history of emesis that became bilious on the last day. The initial evaluation suggested small bowel obstruction. An upper gastrointestinal study confirmed the normal location of the duodenojejunal junction with normal rotation and no evidence of midgut volvulus. Ultrasound (US) evaluation demonstrated two intraluminal lesions that do not follow the typical features of solid or cystic lesions. Two rubber balls were found at surgery to be responsible for the small bowel obstruction. Foreign body ingestion is common in children, but this case demonstrates a unusual foreign object to be ingested as well as the US appearance of this particular foreign body.

Using Lean to Advance Quality Improvement Research.

INTRODUCTION: Quality improvement research skills are not commonplace among quality improvement practitioners, and research on the effectiveness of quality improvement has not always kept pace with improvement innovation. However, the Lean tools applied to quality improvement should be equally relevant to the advancement of quality improvement research. METHODS: We applied the Lean methods to develop a simplified quality improvement publication pathway enabling a small research methodology group to increase quality improvement research throughout the institution. The key innovations of the pathway are horizontal integration of the quality improvement research methods group across the institution, implementation of a Lean quality improvement research pathway, and application of a just-in-time quality improvement research toolkit. RESULTS: This work provides a road map and tools for the acceleration of quality improvement research. At our institution, the Lean quality improvement research approach was associated with statistically significant increases in the number (annual mean increase from 3.0 to 8.5, p = .03) and breadth of published quality improvement research articles, and in the number of quality improvement research projects currently in process. DISCUSSION: Application of Lean methods to the quality improvement research process can aid in increasing publication of quality improvement articles from across the institution.

A comparison of outcomes between laparoscopic and open appendectomy in Canada.

SUMMARY: The benefit of a laparoscopic approach to appendectomy continues to be debated. We compared laparoscopic (LA) with open appendectomy (OA) for appendicitis in Canada using the Canadian Institute for Health Information database (2004-2008). The odds of female patients undergoing LA were 1.26 times higher than the odds of male patients, and the odds of patients with nonperforated pathology undergoing LA were 1.38 times higher than the odds of those with perforated pathology. Increasing comorbidities were associated with OA. While LA is becoming more frequent, the associated length of stay, postoperative complication rate and mortality are clearly lower than for OA. As a result, we support the continued increase in use of LA with regard to both safety and outcomes.

Targeted needs assessment for a transitional "boot camp" curriculum for pediatric surgery residents.

INTRODUCTION: Transition periods in medical education are associated with increased risk for learners and patients. For pediatric surgery residents, the transition to training is especially difficult as learners must adjust to new patient populations. In this study we perform a targeted needs assessment to determine the ideal content and format of a pediatric surgery boot camp to facilitate the transition to residency. METHODS: A needs assessment survey was developed and distributed to pediatric surgery residents and staff across North America. The survey asked participants to rank 30 pediatric surgical diagnoses, 20 skills, and 11 physiological topics on "frequency" and "importance". Items were then ranked using empirical methods. The survey also evaluated the preferred boot camp format. RESULTS: In total, 12 residents and 23 staff completed the survey. No significant differences were identified between staff and residents in survey responses. The top 5 topics identified for inclusion in a boot camp were: (1) fluid and electrolyte management, (2) appendicitis, (3) pediatric hernias, (4) nutrition and (5) pain management. The preferred format for a boot camp was 3-4days in duration applying a blend of educational methods. CONCLUSIONS: Based on the results of the needs assessment survey, a novel pediatric surgery boot camp curriculum can be developed.

Clinical Presentation of Patients With Tension Pneumothorax: A Systematic Review.

OBJECTIVE: To determine whether the reported clinical presentation of tension pneumothorax differs between patients who are breathing unassisted versus receiving assisted ventilation. BACKGROUND: Animal studies suggest that the pathophysiology and physical signs of tension pneumothorax differ by subject ventilatory status. METHODS: We searched electronic databases through to October 15, 2013 for observational studies and case reports/series reporting clinical manifestations of tension pneumothorax. Two physicians independently extracted clinical manifestations reported at diagnosis. RESULTS: We identified 5 cohort studies (n = 310 patients) and 156 case series/reports of 183 cases of tension pneumothorax (n = 86 breathing unassisted, n = 97 receiving assisted ventilation). Hypoxia was reported among 43 (50.0%) cases of tension pneumothorax who were breathing unassisted versus 89 (91.8%) receiving assisted ventilation (P < 0.001). Pulmonary dysfunction progressed to respiratory arrest in 9.3% of cases breathing unassisted. As compared to cases who were breathing unassisted, the adjusted odds of hypotension and cardiac arrest were 12.6 (95% confidence interval, 5.8-27.5) and 17.7 (95% confidence interval, 4.0-78.4) times higher among cases receiving assisted ventilation. One cohort study reported that none of the patients with tension pneumothorax who were breathing unassisted versus 39.6% of those receiving assisted ventilation presented without an arterial pulse. In contrast to cases breathing unassisted, the majority (70.4%) of those receiving assisted ventilation who experienced hypotension or cardiac arrest developed these signs within minutes of clinical presentation. DISCUSSION: The reported clinical presentation of tension pneumothorax depends on the ventilatory status of the patient. This may have implications for improving the diagnosis and treatment of this life-threatening disorder.

Application of Lean Methodology for Improved Quality and Efficiency in Operating Room Instrument Availability.

Advances in surgical instrumentation allow surgeons to treat patients with less morbidity and shorter recovery time. However, the increasing complexity also adds to surgical risk, and to operating room supply chain burden. To improve the quality and efficiency of operating room instrument availability, we developed and validated a Lean 5S approach consisting of sort (determining instrument usage and waste), simplify (removing unnecessary instruments), sweep (confirm availability of needed instruments), standardize (all trays the same for a given procedure), and self-discipline (monitor success). The primary outcome was reduction in unnecessary instruments delivered to the operating room. As a secondary analysis, we evaluated the effect of the Lean instrument intervention on surgery times. We reduced the number of instruments for minimally invasive spine surgery by 70% (from 197 to 58), and setup time decreased 37% (13.1-8.2 min, p = .0015). We also report subsequent validation of the approach on deep brain stimulator cases. We conclude that complex surgical procedures offer opportunities for substantial waste reduction, simplification, and quality improvement, with potential institutional annual cost savings of $2.8 million. We demonstrate that Lean methodology can improve quality at lower cost.

Prevention of delirium in trauma patients: are we giving thiamine prophylaxis a fair chance?

BACKGROUND: Delirium is associated with increased morbidity and mortality in injured patients. Wernicke encephalopathy (WE) is delirium linked to malnutrition and chronic alcoholism. It is prevented with administration of thiamine. Our primary goal was to evaluate current blood alcohol level (BAL) testing and thiamine prophylaxis in severely injured patients. METHODS: We retrospectively reviewed the cases of 1000 consecutive severely injured patients admitted to hospital between Mar. 1, 2009, and Dec. 31, 2009. We used the patients' medical records and the Alberta Trauma Registry. RESULTS: Among 1000 patients (mean age 48 yr, male sex 70%, mean injury severity score 23, mortality 10%), 627 underwent BAL testing at admission; 221 (35%) had a BAL greater than 0 mmol/L, and 189 (30%) had a BAL above the legal limit of 17.4 mmol/L. The mean positive BAL was 41.9 mmol/L. More than 4% had a known history of alcohol abuse. More patients were assaulted (20% v. 9%) or hit by motor vehicles (10% v. 6%) when intoxicated (both p < 0.05). Most injuries occurred after falls (37%) and motor vehicle collisions (33%). Overall, 17% of patients received thiamine prophylaxis. Of the 221 patients with elevated BAL, 44% received thiamine prophylaxis. Of those with a history of alcohol abuse, 77% received thiamine prophylaxis. CONCLUSION: Despite the strong link between alcohol abuse, trauma and WE, more than one-third of patients were not screened for alcohol use. Furthermore, a minority of intoxicated patients received adequate prophylaxis against WE. Given the low risk and cost of BAL testing and thiamine prophylaxis and the high cost of delirium, standard protocols for prophylaxis are essential.

CONTEXTE: Le délire est associé à une morbidité et une mortalité accrues chez les traumatisés. L'encéphalopathie de Wernicke (EW) est un délire associé à la malnutrition et à l'alcoolisme chronique que l'on peut prévenir en administrant de la thiamine. Notre objectif principal était d'évaluer le recours actuel aux tests d'alcoolémie et au traitement prophylactique à la thiamine chez les grands traumatisés. MÉTHODES: Nous avons passé en revue de manière rétrospective 1000 cas consécutifs d'hospitalisation pour traumatismes graves entre le 1er mars 2009 et le 31 décembre 2009. Nous avons utilisé les dossiers médicaux des patients et le Registre des traumatismes de l'Alberta. RÉSULTATS: Sur 1000 patients (âge moyen 48 ans, sexe masculin 70 %, indice moyen de gravité des traumatismes 23, mortalité 10 %), 627 ont subi un test d'alcoolémie à leur admission; 221 (35 %) présentaient un taux d'alcoolémie supérieur à 0 mmol/L et 189 (30 %) avaient un taux d'alcoolémie au-dessus de la limite permise de 17,4 mmol/L. Le taux moyen des tests d'alcoolémie positifs était de 41,9 mmol/L. Plus de 4 % de ces cas avaient des antécédents d'alcoolisme. Les patients qui étaient sous l'effet de l'alcool ont davantage été victimes d'agressions (20 % c. 9 %) ou d'accidents impliquant un véhicule (10 % c. 6 %; tous deux p < 0,05). La majorité des traumatismes ont été causés par des chutes (37 %) ou des accidents de la route (33 %). Dans l'ensemble, 17 % des patients ont reçu un traitement prophylactique à la thiamine. Parmi les 221 patients qui présentaient un taux d'alcoolémie élevé, 44 % ont reçu de la thiamine en prophylaxie. Parmi ceux qui présentaient des antécédents d'abus d'alcool, 77 % ont reçu un traitement prophylactique à la thiamine. CONCLUSION: Malgré le lien étroit entre abus d'alcool, traumatismes et EW, plus du tiers des patients n'ont subi aucun test d'alcoolémie. En outre, seule une minorité de patients intoxiqués ont reçu une prophylaxie adéquate contre l'EW. Compte tenu des risques faibles et des coûts peu élevés du test d'alcoolémie et de la prophylaxie par thiamine et des coûts élevés occasionnés par les épisodes de délire, il est essentiel d'instaurer des protocoles standard de prophylaxie.

Clinical manifestations of tension pneumothorax: protocol for a systematic review and meta-analysis.

BACKGROUND: Although health care providers utilize classically described signs and symptoms to diagnose tension pneumothorax, available literature sources differ in their descriptions of its clinical manifestations. Moreover, while the clinical manifestations of tension pneumothorax have been suggested to differ among subjects of varying respiratory status, it remains unknown if these differences are supported by clinical evidence. Thus, the primary objective of this study is to systematically describe and contrast the clinical manifestations of tension pneumothorax among patients receiving positive pressure ventilation versus those who are breathing unassisted. METHODS/DESIGN: We will search electronic bibliographic databases (MEDLINE, PubMed, EMBASE, and the Cochrane Database of Systematic Reviews) and clinical trial registries from their first available date as well as personal files, identified review articles, and included article bibliographies. Two investigators will independently screen identified article titles and abstracts and select observational (cohort, case-control, and cross-sectional) studies and case reports and series that report original data on clinical manifestations of tension pneumothorax. These investigators will also independently assess risk of bias and extract data. Identified data on the clinical manifestations of tension pneumothorax will be stratified according to whether adult or pediatric study patients were receiving positive pressure ventilation or were breathing unassisted, as well as whether the two investigators independently agreed that the clinical condition of the study patient(s) aligned with a previously published tension pneumothorax working definition. These data will then be summarized using a formal narrative synthesis alongside a meta-analysis of observational studies and then case reports and series where possible. Pooled or combined estimates of the occurrence rate of clinical manifestations will be calculated using random effects models (for observational studies) and generalized estimating equations adjusted for reported potential confounding factors (for case reports and series). DISCUSSION: This study will compile the world literature on tension pneumothorax and provide the first systematic description of the clinical manifestations of the disorder according to presenting patient respiratory status. It will also demonstrate a series of methods that may be used to address difficulties likely to be encountered during the conduct of a meta-analysis of data contained in published case reports and series.

Effects of Postgraduate Medical Education "Boot Camps" on Clinical Skills, Knowledge, and Confidence: A Meta-Analysis.

BACKGROUND: Throughout their medical education, learners face multiple transition periods associated with increased demands, producing stress and concern about the adequacy of their skills for their new role. OBJECTIVE: We evaluated the effectiveness of boot camps in improving clinical skills, knowledge, and confidence during transitions into postgraduate or discipline-specific residency programs. METHODS: Boot camps are in-training courses combining simulation-based practice with other educational methods to enhance learning and preparation for individuals entering new clinical roles. We performed a search of MEDLINE, CINAHL, PsycINFO, EMBASE, and ERIC using boot camp and comparable search terms. Inclusion criteria included studies that reported on medical education boot camps, involved learners entering new clinical roles in North American programs, and reported empirical data on the effectiveness of boot camps to improve clinical skills, knowledge, and/or confidence. A random effects model meta-analysis was performed to combined mean effect size differences (Cohen's d) across studies based on pretest/posttest or comparison group analyses. RESULTS: The search returned 1096 articles, 15 of which met all inclusion criteria. Combined effect size estimates showed learners who completed boot camp courses had significantly "large" improvements in clinical skills (d  =  1.78; 95% CI 1.33-2.22; P < .001), knowledge (d  =  2.08; 95% CI 1.20-2.96; P < .001), and confidence (d  =  1.89; 95% CI 1.63-2.15; P < .001). CONCLUSIONS: Boot camps were shown as an effective educational strategy to improve learners' clinical skills, knowledge, and confidence. Focus on pretest/posttest research designs limits the strength of these findings.

The impact of multi-disciplinary intestinal rehabilitation programs on the outcome of pediatric patients with intestinal failure: a systematic review and meta-analysis.

BACKGROUND: Pediatric intestinal failure (IF) is a complex clinical problem requiring coordinated multi-disciplinary care. Our objective was to review the evidence for the benefit of intestinal rehabilitation programs (IRP) in pediatric IF patients. METHODS: A systematic review was performed on Medline (1950-2012), Pubmed (1966-2012), and Embase (1980-2012) conference proceedings and trial registries. The terms short bowel syndrome, intestinal rehabilitation, intestinal failure, patient care teams, and multi-disciplinary teams were used. Fifteen independent studies were included. Three studies that were cohort studies, including a comparison group, were included in a meta-analysis. RESULTS: Compared to historical controls (n=103), implementation of an IRP (n=130) resulted in a reduction in septic episodes (0.3 vs. 0.5 event/month; p=0.01) and an increase in overall patient survival (22% to 42%). Non-significant improvements were seen in weaning from PN (RR=1.05, 0.88-1.25, p=0.62), incidence of IFALD (RR=0.2, 0-17.25, p=0.48), and relative risk of liver transplantation (3.99, 0.75-21.3, p=0.11). Other outcomes reported included a reduction in calories from parenteral nutrition (100% to 32%-56%), earlier surgical/transplant evaluation, and improved coordination of patient care. CONCLUSION: For pediatric IF patients, IRPs are associated with reduced morbidity and mortality. Standardized clinical practice guidelines are necessary to provide uniform patient care and outcome assessment.
