RESUMO

CONTEXT: Transrectal ultrasound-guided prostate biopsy (TRPB) has been a standard of care for diagnosing prostate cancer but is associated with a high incidence of infectious complications. OBJECTIVE: To achieve an expert consensus on whether fosfomycin trometamol provides adequate prophylaxis in TRPB and discuss its role as prophylaxis in transperineal prostate biopsy (TPPB). EVIDENCE ACQUISITION: An international multidisciplinary group of experts convened remotely to discuss how to best use fosfomycin in various clinical settings and patient situations. Six statements related to prostate biopsy and the role of fosfomycin were developed, based on literature searches and relevant clinical experience. EVIDENCE SYNTHESIS: Consensus was reached for all six statements. The group of experts was unanimous regarding fosfomycin as a preferred candidate for antimicrobial prophylaxis in TRPB. Fosfomycin potentially also meets the requirements for empiric prophylaxis in TPPB, although further clinical studies are needed to confirm or refute its utility in this setting. There is a risk of bias due to sponsorship by a pharmaceutical company. CONCLUSIONS: Antimicrobial prophylaxis is mandatory in TRPB, and fosfomycin trometamol is an appropriate candidate due to low rates of resistance, a good safety profile, sufficient prostate concentrations, and demonstrated efficacy in reducing the risk of infectious complications following TRPB. PATIENT SUMMARY: Patients undergoing transrectal ultrasound-guided prostate biopsy (TRPB) have a high risk of infectious complications, and antimicrobial prophylaxis is mandatory. However, increasing antimicrobial resistance, as well as safety concerns with fluoroquinolones, has restricted the number of antimicrobial options. Fosfomycin trometamol meets the requirements for a preferred antimicrobial in the prophylaxis of TRPB.

RESUMO

Pharmacological HIV-1 reactivation to reverse latent infection has been extensively studied. However, HIV-1 reactivation also occurs naturally, as evidenced by occasional low-level viremia ("viral blips") during antiretroviral treatment (ART). Clarifying where blips originate from and how they happen could provide clues to stimulate latency reversal more effectively and safely or to prevent viral rebound following ART cessation. We studied HIV-1 reactivation in the female genital tract, a dynamic anatomical target for HIV-1 infection throughout all disease stages. We found that primary endocervical epithelial cells from several women reactivated HIV-1 from latently infected T cells. The endocervical cells' HIV-1 reactivation capacity further increased upon Toll-like receptor 3 stimulation with poly(I·C) double-stranded RNA or infection with herpes simplex virus 2 (HSV-2). Notably, acyclovir did not eliminate HSV-2-induced HIV-1 reactivation. While endocervical epithelial cells secreted large amounts of several cytokines and chemokines, especially tumor necrosis factor alpha (TNF-α), CCL3, CCL4, and CCL20, their HIV-1 reactivation capacity was almost completely blocked by TNF-α neutralization alone. Thus, immunosurveillance activities by columnar epithelial cells in the endocervix can cause endogenous HIV-1 reactivation, which may contribute to viral blips during ART or rebound following ART interruption.IMPORTANCE A reason that there is no universal cure for HIV-1 is that the virus can hide in the genome of infected cells in the form of latent proviral DNA. This hidden provirus is protected from antiviral drugs until it eventually reactivates to produce new virions. It is not well understood where in the body or how this reactivation occurs. We studied HIV-1 reactivation in the female genital tract, which is often the portal of HIV-1 entry and which remains a site of infection throughout the disease. We found that the columnar epithelial cells lining the endocervix, the lower part of the uterus, are particularly effective in reactivating HIV-1 from infected T cells. This activity was enhanced by certain microbial stimuli, including herpes simplex virus 2, and blocked by antibodies against the inflammatory cytokine TNF-α. Avoiding HIV-1 reactivation could be important for maintaining a functional HIV-1 cure when antiviral therapy is stopped.

RESUMO

BACKGROUND: Cryopreservation of leukocytes isolated from the cervicovaginal and colorectal mucosa is useful for the study of cellular immunity (see Hughes SM et al. PLOS ONE 2016). However, some questions about mucosal biology and sexually transmitted infections are better addressed with intact mucosal tissue, for which there is no standard cryopreservation protocol. METHODS AND FINDINGS: To find an optimal preservation protocol for mucosal tissues, we tested slow cooling (1°C/min) with 10% dimethylsulfoxide (designated "cryopreservation") and fast cooling (plunge in liquid nitrogen) with 20% dimethylsulfoxide and 20% ethylene glycol ("vitrification"). We compared fresh and preserved human cervicovaginal and colorectal tissues in a range of assays, including metabolic activity, human immunodeficiency virus infection, cell phenotype, tissue structure by hematoxylin-and-eosin staining, cell number and viability, production of cytokines, and microbicide drug concentrations. Metabolic activity, HIV infectability, and tissue structure were similar in cryopreserved and vitrified vaginal tissues. However, vitrification led to poor cell recovery from the colorectal mucosa, with 90% fewer cells recovered after isolation from vitrified colorectal tissues than from cryopreserved. HIV infection rates were similar for fresh and cryopreserved ectocervical tissues, whereas cryopreserved colorectal tissues were less easily infected than fresh tissues (hazard ratio 0.7 [95% confidence interval 0.4, 1.2]). Finally, we compared isolation of cells before and after cryopreservation. Cell recoveries were higher when cells were isolated after freezing and thawing (71% [59-84%]) than before (50% [38-62%]). Cellular function was similar to fresh tissue in both cases. Microbicide drug concentrations were lower in cryopreserved explants compared to fresh ones. CONCLUSIONS: Cryopreservation of intact cervicovaginal and colorectal tissues with dimethylsulfoxide works well in a range of assays, while the utility of vitrification is more limited. Cell yields are higher from cryopreserved intact tissue pieces than from thawed cryopreserved single cell suspensions isolated before freezing, but T cell functions are similar.

RESUMO

Cryopreservation of specimens taken from the genital tract of women is important for studying mucosal immunity during HIV prevention trials. However, it is unclear whether the current, empirically developed cryopreservation procedures for peripheral blood cells are also ideal for genital specimens. The optimal cryopreservation protocol depends on the cryobiological features of the cells. Thus, we obtained tissue specimens from vaginal repair surgeries, isolated and flow cytometry-purified immune cells, and determined fundamental cryobiological characteristics of vaginal CD3(+) T cells and CD14(+) macrophages using a microfluidic device. The osmotically inactive volumes of the two cell types (Vb) were determined relative to the initial cell volume (V0) by exposing the cells to hypotonic and hypertonic saline solutions, evaluating the equilibrium volume, and applying the Boyle van't Hoff relationship. The cell membrane permeability to water (Lp) and to four different cryoprotective agent (CPA) solutions (Ps) at room temperature were also measured. Results indicated Vb values of 0.516 V0 and 0.457 V0 for mucosal T cells and macrophages, respectively. Lp values at room temperature were 0.196 and 0.295 µm/min/atm for T cells and macrophages, respectively. Both cell types had high Ps values for the three CPAs, dimethyl sulfoxide (DMSO), propylene glycol (PG) and ethylene glycol (EG) (minimum of 0.418 × 10(-3) cm/min), but transport of the fourth CPA, glycerol, occurred 50-150 times more slowly. Thus, DMSO, PG, and EG are better options than glycerol in avoiding severe cell volume excursion and osmotic injury during CPA addition and removal for cryopreservation of human vaginal immune cells.

RESUMO

To study mucosal immunity and conduct HIV vaccine trials, it is important to be able to cryopreserve mucosal specimens and recover them in functional viable form. Obtaining a good recovery depends, in part, on cooling the cells at the appropriate rate, which is determined by the rate of water transport across the cell membrane during the cooling process. In this study, the cell membrane permeabilities to water at subzero temperatures of human vaginal mucosal T cells and macrophages were measured using the differential scanning calorimetry method proposed by Devireddy et al. in 1998. Thermal histograms were measured before and after cell lysis using a Slow-Fast-Fast-Slow cooling program. The difference between the thermal histograms of the live intact cells and the dead lysed cells was used to calculate the temperature-dependent cell membrane permeability at subzero temperatures, which was assumed to follow the Arrhenius relationship, [Formula: see text], where Lpg is the permeability to water at the reference temperature (273.15 K). The results showed that Lpg = 0.0209 ± 0.0108 µm/atm/min and Ea = 41.5 ± 11.4 kcal/mol for T cells and Lpg = 0.0198 ± 0.0102 µm/atm/min and Ea = 38.2 ± 10.4 kcal/mol for macrophages, respectively, in the range 0°C to -40°C (mean ± standard deviation). Theoretical simulations predicted that the optimal cooling rate for both T cells and macrophages was about -3°C/min, which was proven by preliminary immune cell cryopreservation experiments.

RESUMO

AIMS: To determine OB/GYN residents' experience with and opinions toward cystoscopy at the time of hysterectomy. STUDY DESIGN: An internet survey of OB/GYN residents assessed utilization of cystoscopy at the time of hysterectomy, familiarity with literature regarding universal versus selective cystoscopy, and plans post residency. RESULTS: Cystoscopy was performed universally in the minority of cases of vaginal hysterectomy (12%), laparoscopically assisted vaginal hysterectomy (14%), supracervical hysterectomy (0%), total abdominal hysterectomy (2%), laparoscopic supracervical hysterectomy (9%), total laparoscopic hysterectomy (27%), and hysterectomy with adnexa removal (5%). Residents planned universal cystoscopy post-training more frequently for all hysterectomy types. CONCLUSION: Cystoscopy at the time of hysterectomy was performed universally in the minority for all hysterectomy categories. For all hysterectomy types, residents planned post-graduation to utilize universal cystoscopy at the time of hysterectomy more often than occurred in training.

RESUMO

BACKGROUND: Functional analysis of mononuclear leukocytes in the female genital mucosa is essential for understanding the immunologic effects of HIV vaccines and microbicides at the site of HIV exposure. However, the best female genital tract sampling technique is unclear. METHODS AND FINDINGS: We enrolled women from four sites in Africa and the US to compare three genital leukocyte sampling methods: cervicovaginal lavages (CVL), endocervical cytobrushes, and ectocervical biopsies. Absolute yields of mononuclear leukocyte subpopulations were determined by flow cytometric bead-based cell counting. Of the non-invasive sampling types, two combined sequential cytobrushes yielded significantly more viable mononuclear leukocytes than a CVL (p<0.0001). In a subsequent comparison, two cytobrushes yielded as many leukocytes (∼ 10,000) as one biopsy, with macrophages/monocytes being more prominent in cytobrushes and T lymphocytes in biopsies. Sample yields were consistent between sites. In a subgroup analysis, we observed significant reproducibility between replicate same-day biopsies (r = 0.89, p = 0.0123). Visible red blood cells in cytobrushes increased leukocyte yields more than three-fold (p = 0.0078), but did not change their subpopulation profile, indicating that these leukocytes were still largely derived from the mucosa and not peripheral blood. We also confirmed that many CD4(+) T cells in the female genital tract express the α4ß7 integrin, an HIV envelope-binding mucosal homing receptor. CONCLUSIONS: CVL sampling recovered the lowest number of viable mononuclear leukocytes. Two cervical cytobrushes yielded comparable total numbers of viable leukocytes to one biopsy, but cytobrushes and biopsies were biased toward macrophages and T lymphocytes, respectively. Our study also established the feasibility of obtaining consistent flow cytometric analyses of isolated genital cells from four study sites in the US and Africa. These data represent an important step towards implementing mucosal cell sampling in international clinical trials of HIV prevention.

RESUMO

BACKGROUND: Numerous constraints may limit the practical experience of surgical residents. Current research supports a need for structured curricula, skills acquisition, and feedback outside the operating room (OR) and formal assessment of technical skills. We examined the current state of surgical skill teaching and evaluation for Canadian residents across surgical specialties. METHODS: One hundred twenty-three surveys were mailed to surgical residency program directors of all 17 Canadian medical schools. Nine surgical specialties were identified. Program demographics, details of surgical skill teaching methods, and several surgical skill assessment modalities used from admission to graduation were surveyed. Obstetrics and Gynecology (ObGyn) survey results were compared with other surgical specialties. RESULTS: Seventy surveys (57%) from 15 medical schools (88%) were returned. All specialties were represented in responses. ObGyn residents had fewer surgical training months per year than other residents (4.9 versus 8.5 months; p = 0.001). The most common teaching method was didactic lectures (86%; 95% confidence interval [CI], 75%-93%) for all programs. Inanimate and/or animate skills laboratories and didactic lectures were equally used by 90% (95% CI, 55%-100%) of ObGyn programs. Virtual reality simulators for procedure-specific surgical skills ranked low at 30% (95% CI, 7%-65%) use in ObGyn programs. Most programs had a dedicated space to teach and practice skills outside the OR. Assessment, feedback, and determination of surgical competence were most commonly performed via subjective evaluation by surgical mentors. Forty percent of ObGyn programs versus 76% of other programs used a local program-specific surgical training curriculum (p = 0.054). Most program directors who did not have access to a standard training curriculum wished to have one implemented. CONCLUSIONS: Lectures and subjective evaluations are the most common educational tools in Canadian surgical residencies. Despite the availability of validated surgical teaching and evaluation tools remote from the OR, standard training curricula are not the norm in Canadian ObGyn residency programs.

RESUMO

Treatment of early-stage cervical and endometrial cancer has been associated with significant sexual difficulties in at least half of women following hysterectomy. Despite the fact that women report such sexual side effects to be the most distressing aspect of their cancer treatment, evidence-based treatments for Female Sexual Arousal Disorder (FSAD), the most common sexual symptom in this group, do not exist. We developed and pilot tested a brief, three session psychoeducational intervention (PED) targeting FSAD in 22 women with early-stage gynecologic cancer. The PED consisted of three, 1-h sessions that combined elements of cognitive and behavioral therapy with education and mindfulness training. Women completed questionnaires and had a physiological measurement of genital arousal at pre- and post-PED (sessions 1 and 4) and participated in a semi-structured interview (session 4) during which their feedback on the PED was elicited. There was a significant positive effect of the PED on sexual desire, arousal, orgasm, satisfaction, sexual distress, depression, and overall well-being, and a trend towards significantly improved physiological genital arousal and perceived genital arousal. Qualitative feedback indicated that the PED materials were very user-friendly, clear, and helpful. In particular, women reported the mindfulness component to be most helpful. These findings suggest that a brief 3-session PED can significantly improve aspects of sexual response, mood, and quality of life in gynecologic cancer patients, and has implications for establishing the components of a psychological treatment program for FSAD.

RESUMO

OBJECTIVE: The purpose of this study was to develop an effective curriculum for teaching colposuspension and diagnostic cystoscopy. STUDY DESIGN: Fifty-five residents underwent an Objective Structured Assessment of Technical Skills that was composed of a task-specific checklist and validated global assessment. Thirty of the residents had been exposed to a training curriculum, and 25 residents served as untrained control subjects. RESULTS: For the colposuspension and cystoscopy checklists, the reliability coefficient was 0.85 and 0.72, and the interrater reliability was 0.92 and 0.68, respectively. Although residents who were provided the curriculum performed better on both task-specific checklists, the differences did not reach statistical significance. Senior residents performed consistently better than junior residents for both tasks. When a comparison was made of the junior residents separately to account for previous experience, trained residents performed significantly better on the cystoscopy checklist (P = .029). CONCLUSION: This curriculum is an effective way to teach diagnostic cystoscopy to junior residents. The checklist for this Objective Structured Assessment of Technical Skills has good reliability and construct validity.

RESUMO

OBJECTIVE: The purpose of this study was to examine obstetrics and gynecology residents' self-assessment of proficiency on a variety of surgical bench procedures and to compare their ratings with those ratings of trained faculty observers who used instruments that have been shown to be reliable and valid. STUDY DESIGN: As part of a 6-station Objective Structured Assessment of Technical Skills, 74 residents at 5 institutions estimated their overall open and laparoscopic skill level before the testing. After completing each station, residents evaluated their overall and global skills performance. RESULTS: Residents rated their proficiency higher on open skills than on laparoscopic skills. Task-specific, overall, and global assessments were correlated significantly with the faculty ratings (P < .001). Residents tended to rate themselves lower than did faculty on almost all measures; even those residents with poor skills indicated that they were aware of their deficiencies. Overall and global self-assessments increased with each resident level, which indicated good construct validity. CONCLUSION: Residents can rate their overall open and laparoscopic skills, task-specific performance, and global skills with good reliability and validity. Although they tended to score themselves lower than did faculty observers, the correlations are high (ie, residents who give themselves a higher score tended to receive a higher score from faculty, and vice versa). One of the concerns about self-assessment is that residents with poor skills might not be aware of their deficiencies. We did not find that to be the case. Therefore, when residents work on self-directed exercises, task-specific and global checklists can be used for both learning and self-assessment.

RESUMO

AIMS: To describe the course of reported musculoskeletal pain in the temporomandibular region and other signs and symptoms of temporomandibular disorders (TMD) as well as psychological distress over the course of pregnancy and 1 year postpartum. METHODS: Women with musculoskeletal orofacial pain (n = 19) and pain-free comparison subjects (n = 16) in the first trimester of pregnancy were selected through records review from the population of a large health maintenance organization. Subjects completed a self-administered questionnaire assessing pain, depression, and somatic symptoms; provided a sample of whole unstimulated saliva; and underwent a standardized clinical examination during the third, sixth, and ninth months of pregnancy and 1 year postpartum. RESULTS: At baseline (third month of pregnancy), 16 of the 19 patients with musculoskeletal orofacial pain met criteria for an RDC/TMD diagnosis. Reported musculoskeletal orofacial pain diminished significantly during the second or third trimester of pregnancy and increased again postpartum. Measures of mandibular opening increased over pregnancy in both cases and comparison subjects and remained high postpartum. Depression and somatic symptoms changed little over the course of pregnancy but were substantially lowered at 1 year postpartum for both groups. As expected, subjects with pain had higher levels of palpation pain, diminished mandibular range of motion, and higher levels of psychological distress compared to subjects without orofacial pain. CONCLUSION: Musculoskeletal orofacial pain and related symptoms appear to improve over the course of pregnancy. This improvement occurs in the presence of increased joint laxity and is not paralleled by improvements in psychological distress. Thus, it was concluded that the improvement in pain is most likely associated with the dramatic hormonal changes occurring during pregnancy.

RESUMO

OBJECTIVE: We have previously shown that in a single residency program objective structured assessment of technical skills (OSATS) is a reliable and valid method of assessing surgical competency. Our goal was to establish feasibility of this evaluation instrument when administered at multiple residency programs throughout the US, and assess the impact of a laboratory-based surgical curriculum on results. STUDY DESIGN: An OSATS exam was administered to 116 residents from 5 residency programs. One of the residency programs had participated in a comprehensive surgical curriculum over a 4-year period of time. The exam consisted of 3 open and 3 laparoscopic tasks. Residents were graded by both a blinded and unblinded examiner with task-specific checklist, global rating scale, pass/fail assessment, and tasks were timed. All tasks were performed on life-like models. RESULTS: Examinations were successfully completed at all sites. Each exam required 90 minutes of resident time. Reliability indices calculated with Cronbach's alpha were .97 for overall global rating and .95 for checklists. Interrater reliability between blinded and unblinded examiners ranged from .71 to .97 for individual tasks and was .95 overall. Assessment of construct validity (the ability to distinguish among residency levels) found significant differences among the residents for both blinded and unblinded examiners for all evaluation outcomes except time. For the test overall, the global rating scale showed significant differences among all 4 residency levels. The checklist showed significant differences at three levels (PGY3-4 >PGY2 >PGY1). Approximate cost for replaceable items was 40 US dollars to 150 per resident depending on which tasks were chosen. Comparison of scores between residents who received a laboratory-based curriculum and those who did not revealed significantly higher scores and shorter time to complete tasks for the group who received additional training. CONCLUSION: Large-scale testing has confirmed that OSATS is an objective, reliable, and valid method to assess surgical skills, and can easily be administered in most residency programs. A laboratory-based surgical curriculum improved test results and reduced time to complete tasks.

RESUMO

OBJECTIVES: To evaluate the history and management of complications from transvaginally placed pubovaginal slings using bone anchor fixation. METHODS: During a 3-year period, 10 patients were referred to us for complications related to transvaginally placed pubovaginal slings using bone anchor fixation. RESULTS: The patient age ranged from 42 to 73 years. All women had a vaginally introduced bone anchor sling for stress urinary incontinence. The presenting symptoms after surgery included fever, pain, and difficulty ambulating in 1; pain and/or vaginal dyspareunia with discharge in 5; pain or dyspareunia alone in 2; and vaginal discharge alone in 2 patients. Two patients ultimately developed bone lesions on radiologic studies consistent with osteomyelitis. Six patients developed sinus drainage tracts associated with granulation tissue from at least one bone anchor that was unresponsive to outpatient management. One of the patients with pain alone had a permanent suture extending into the bladder neck. Nine patients underwent surgery, of whom five had resolution of their presenting complaint. Four of these patients were continent at last follow-up. CONCLUSIONS: Transvaginally placed pubovaginal slings using bone anchors can be associated with serious complications that may be intractable to common therapies. This knowledge may enable practitioners who use this technique to better counsel their patients regarding these significant complications.

RESUMO

OBJECTIVE: The purpose of this study was to describe the pelvic floor neuromuscular function and posterior compartment symptoms in patients with posterior vaginal wall prolapse. STUDY DESIGN: Two hundred twenty-seven women who were referred to a urogynecology and urology clinic were enrolled prospectively. Each patient completed a health history questionnaire and standardized physical examination that specifically graded uterovaginal prolapse according to the pelvic organ prolapse quantification system. RESULTS: Sixty-nine women had a pelvic organ prolapse quantification system point (most dependent portion of the posterior vaginal wall during straining as measured from the hymeneal ring) of < or =-1. Older age, a history of hysterectomy, a genital hiatus of >3 cm (48% vs 24%; P =.002), and perineal descent of > or =2 cm (14% vs 5%; P =.042) were significantly more common in women with posterior vaginal prolapse. When women with posterior prolapse and symptomatic complaints were compared with asymptomatic women with prolapse, a perineal descent of > or =2 cm (21% vs 0%; P =.004) was significantly more common in the symptomatic group. CONCLUSION: Pelvic floor neuromuscular function should be related to posterior vaginal prolapse and symptoms; however, only perineal descent appears associated strongly with both symptoms and prolapse in this population.

RESUMO

OBJECTIVE: Chronic, painful bladder symptoms are diagnostic and therapeutic challenges for urologists and gynecologists. The aims of this study were to evaluate women with menstrual cycle-related changes in their interstitial cystitis symptoms, to treat them with hormonal manipulation, and to follow them long term. STUDY DESIGN: The cases of women who were referred to a tertiary care center with interstitial cystitis and menstrual cycle exacerbation of symptoms were evaluated in a retrospective study. Fifteen women had undergone laparoscopy that was followed immediately by cystoscopy and bladder hydrodistension. Patients were then treated with leuprolide acetate or oral contraceptive pills. RESULTS: Patient age ranged from 23 to 48 years. The duration of symptoms ranged from 1 to 26 years. Ten patients (67%) had findings of both interstitial cystitis and peritoneal endometriosis. Five of 15 patients (33%) had interstitial cystitis, but no endometriosis was found. Symptoms improved for 8 of 9 women who were treated with leuprolide acetate and for 5 of 6 women who were treated with oral contraceptive pills. Patients were followed up for an average of 55 months. CONCLUSION: Diagnostic laparoscopy should be considered together with hydrodistension of the bladder for women with pelvic pain and irritative bladder symptoms that are exacerbated premenstrually. Endometriosis is often present in patients with these complex symptoms. This is the first report of hormonal treatment for chronic, cyclic irritative bladder symptoms; improvement appears to occur even when endometriosis is not identified by laparoscopy.

RESUMO

OBJECTIVE: We have previously shown that objective structured assessment of technical skills (OSATS) is an innovative, reliable, and valid method of assessing surgical skills. Our goal was to establish the feasibility, reliability, and validity of our surgical skills assessment instrument when administered in a blinded fashion. STUDY DESIGN: A 7-station OSATS was administered to 16 obstetric and gynecology residents from Madigan Army Medical Center. The test included laparoscopic (salpingostomy, intracorporeal knot, and ligation of vessels with clips) and open abdominal procedures (subcuticular closure, bladder neck suspension, enterotomy repair, and abdominal wall closure). All tasks were performed with lifelike surgical models. Residents were timed and assessed at each station with 3 methods of scoring: task-specific checklist, global rating scale, and pass/fail grade. Each resident was evaluated by one examiner blinded as to the postgraduate year level and one examiner who had previously worked with the resident. RESULTS: Assessment of construct validity (the ability to distinguish between resident levels) found significant differences on the checklist, global rating scale, and pass/fail grade by residency level for both blinded and unblinded examiners. Reliability indices calculated with Cronbach's alpha were.82 for the checklists and.93 for the global rating scale. Overall interrater reliability between blinded and unblinded examiners was 0.95 for global rating scale and ranged from 0.74 to 0.97 for the checklists. The cost to administer the exam for the 16 residents was approximately $1000. CONCLUSIONS: OSATS administered in either a blinded or unblinded fashion can assess residents' surgical skills with a high degree of reliability and validity. This study provides further evidence that OSATS can be used to establish surgical competence.
