Enabling Technologies for Gynecologic Vaginal Surgery: A Systematic Review.

OBJECTIVE: To systematically review the literature to evaluate clinical and surgical outcomes for technologies that facilitate vaginal surgical procedures. DATA SOURCES: We systematically searched MEDLINE, EMBASE, and ClinicalTrials.gov from January 1990 to May 2022. METHODS OF STUDY SELECTION: Comparative and single-arm studies with data on contemporary tools or technologies facilitating intraoperative performance of vaginal gynecologic surgical procedures for benign indications were included. Citations were independently double screened, and eligible full-text articles were extracted by two reviewers. Data collected included study characteristics, technology, patient demographics, and intraoperative and postoperative outcomes. Risk of bias for comparative studies was assessed using established methods, and restricted maximum likelihood model meta-analyses were conducted as indicated. TABULATION, INTEGRATION, AND RESULTS: The search yielded 8,658 abstracts, with 116 eligible studies that evaluated pedicle sealing devices (n=32), nonrobotic and robotic vaginal natural orifice transluminal endoscopic surgery (n=64), suture capture devices (n=17), loop ligatures (n=2), and table-mounted telescopic cameras (n=1). Based on 19 comparative studies, pedicle sealing devices lowered vaginal hysterectomy operative time by 15.9 minutes (95% CI, -23.3 to -85), blood loss by 36.9 mL (95% CI, -56.9 to -17.0), hospital stay by 0.2 days (95% CI, -0.4 to -0.1), and visual analog scale pain scores by 1.4 points on a subjective 10-point scale (95% CI, -1.7 to -1.1). Three nonrandomized comparative studies and 53 single-arm studies supported the feasibility of nonrobotic vaginal natural orifice transluminal endoscopic surgery for hysterectomy, adnexal surgery, pelvic reconstruction, and myomectomy. Data were limited for robotic vaginal natural orifice transluminal endoscopic surgery, suture capture devices, loop ligatures, and table-mounted cameras due to few studies or study heterogeneity. CONCLUSION: Pedicle sealing devices lower operative time and blood loss for vaginal hysterectomy, with modest reductions in hospital stay and pain scores. Although other technologies identified in the literature may have potential to facilitate vaginal surgical procedures and improve outcomes, additional comparative effectiveness research is needed.

Ice-POP: Ice Packs for Postoperative Pain: A Randomized Controlled Trial.

STUDY OBJECTIVE: To evaluate the benefit of ice packs as a supplement to standard pain management following laparoscopic hysterectomy (LH). DESIGN: This Institutional Review Board-approved randomized controlled trial involved patients undergoing LH for benign conditions. Subjects were randomized to receive standard enhanced recovery after surgery pain management or standard enhanced recovery after surgery plus ice packs. SETTING: Two academic tertiary care centers PATIENTS: Patients undergoing planned outpatient LH with the minimally invasive gynecologic surgery team between February 2019 and November 2020 were considered. Patients with chronic pain, current opioid use ≥1 week, or planned overnight hospitalizations were excluded. Primary outcome data were available for 51 subjects (24 control, 27 intervention). INTERVENTIONS: Ice packs were placed on the abdomen in the operating room. MEASUREMENTS AND MAIN RESULTS: Pain was assessed at multiple time points throughout the study using a visual analogue scale (VAS). Opioid requirement was assessed using morphine milligram equivalent. There was no difference between the groups on any demographic variables. Morphine milligram equivalent requirements were also not different between the groups (p = .63). Postoperative day 1 (POD#1) VAS scores were not different (p = .89). Eighty-five percent of subjects reported feeling that their pain was controlled. Subjects who reported that they did not feel their pain was controlled did not use more opioids on POD#1 (p = .37), nor did they have higher POD#1 VAS scores (p = .55). Eighty-seven percent of the intervention subjects said they would use ice again, and 82.6% of them said they would recommend ice to others. There were no adverse events related to ice. All subjects were prescribed 20 tablets oxycodone and averaged 2.9 (SD 3.4) tablets used after discharge. CONCLUSION: Ice packs are an acceptable supplement for postoperative pain control, but they do not reduce postoperative pain or opioid usage compared to standard pain management without ice packs.

A Mindfulness Application for Reducing Prenatal Stress.

INTRODUCTION: Up to 40% of patients report depression or anxiety symptoms in pregnancy; feelings of increased stress are nearly universal. Antepartum stress is linked to adverse outcomes including preterm birth, low birthweight, postpartum depression, and maternal self harm. Unfortunately, limited treatment options exist, and patients are often hesitant to initiate medications prenatally. Thus, the development of efficacious nonpharmacologic interventions is crucial. This pilot study investigated the feasibility and impact of an application (app)-based mindfulness practice, begun in the first trimester, on maternal stress and pregnancy outcomes. METHODS: The study enrolled patients prior to 15 weeks' gestation and followed them prospectively through birth. Patients were provided with a free subscription to Expectful, a commercially available prenatal mindfulness app, and asked to complete daily meditations. Patients completed the Perceived Stress Scale (PSS) self-assessment at 15 weeks and 28 weeks. PSS scores and pregnancy outcomes were compared with a historical control group of pregnant people who did not use the app. RESULTS: Of 68 patients approached, 59 consented to enrollment. Of these, 21 used the app, with an average use of 170 minutes (range, 1.3-1315 min). The average PSS score was significantly lower in the app group at 28 weeks. Additionally, the change in PSS score for app users was greater compared with that of the historical control between enrollment and 28 weeks (-6.3 vs -0.95, P = .0008). Pregnancy outcomes were similar for app users and the historical control. DISCUSSION: Our recruitment rate suggests pregnant patients are eager for a nonmedication intervention to decrease stress. However, adherence after enrollment was limited. For a subset of motivated patients, an app-based mindfulness practice significantly reduced perceived stress between the second and third trimesters compared with non-app users. Prenatal mindfulness apps represent an important low-intervention, low-cost, highly accessible tool for managing perinatal mood and stress.

Preparing for the Fundamentals of Laparoscopic Surgery Exam: A Survey of Residents in Obstetrics & Gynecology.

OBJECTIVE: To describe the actual work-load and experience for first-time resident test takers preparing to meet the new high stakes cognitive and technical skills testing requirement for board certification in Obstetrics and Gynecology. DESIGN: A retrospective observational study. Participating residents completed a 2 page questionnaire about their preparation for the exam. Results are reported in aggregate. SETTING: This study was conducted at the University of Texas Southwestern Medical Center, an academic medical school affiliated with both a private and public tertiary hospitals. PARTICIPANTS: Residents in obstetrics and gynecology who have completed their Fundamentals of Laparoscopic Surgery (FLS) certification exam between September 1, 2018 and September 31, 2019. Thirty-three PGY-2 and PGY-3 residents completed the survey. RESULTS: Participants spent an average of 6.7 ± 3.1 hours viewing online modules over an average of 3.6 ± 2.1 nonconsecutive days. Utilizing the campus simulation center, residents spent an average of 2.1 ± 2.1 hours on each of the 5 tasks to practice to the established proficiency score. Twenty-two out of 31 residents rated the ligating loop the easiest skill to master and 13/31 residents rated the precision cut the most difficult. The pass rate for the technical skills portion was 100% (33/33 residents) and for the cognitive portion was 93% (31/33 residents). CONCLUSIONS: Our data suggest that residents spent upward of 10 hours practicing to proficiency on the simulation tasks, in addition to time spent watching FLS-provided training videos. The 100% pass rate for the technical skills portion at our program may be impacted by a required technical skills curriculum that residents must complete prior to registering for the FLS exam. Obstetrics and gynecology residents and training programs will benefit from understanding the time and resources required for first-time resident test takers preparing to take the Fundamentals of Laparoscopic Surgery exam.

Continuous local bupivacaine wound infusion reduces oral opioid use for acute postoperative pain control following myelomeningocele repair.

BACKGROUND: For pregnancies complicated by fetal myelomeningocele who meet the established criteria, prenatal closure is a viable management option. Prenatal closure is an open procedure, with some techniques requiring greater dissection of maternal tissue than cesarean delivery; pain control is an important postoperative goal. Given the rising rates of opioid dependence and concerns regarding the fetal and neonatal effects of opioid use, our practice has turned to nonopioid pain management techniques. OBJECTIVE: This study aimed to compare postoperative opioid use and pain scores in women undergoing open fetal myelomeningocele repair with and without continuous local bupivacaine wound infusion. STUDY DESIGN: This was a retrospective, single-center chart review of all consecutive patients who underwent open myelomeningocele repair from March 2013 to December 2019. Women were enrolled at the time of referral and locally followed for 2 weeks postoperatively. The control group received patient-controlled epidural analgesia for 48 hours with acetaminophen and oral and intravenous opioids as needed. The treatment group received patient-controlled epidural analgesia for 24 hours with acetaminophen, oral and intravenous opioids, and continuous local bupivacaine infusion. Pain scores, medication use, and postoperative milestones and complications through discharge were abstracted from the chart and compared. RESULTS: Of 72 subjects, 51 were in the control group and 21 in the treatment group. Total opioid use, including intravenous doses (165 vs 52.5 mg; P=.001) and daily average oral opioid use (30 vs 10.5 mg; P=.002) were lower in the treatment group. In addition, 24% of women in the treatment group used no opioid postoperatively, compared with 4% in the control group. There was no difference in postoperative day 1 to 4 pain scores, antiemetic use, or bowel function; the treatment group was discharged significantly earlier. CONCLUSION: Postoperative opioid use was reduced in women who received continuous local wound infusion of bupivacaine for incisional pain control after prenatal myelomeningocele repair. Pain control is paramount following open myelomeningocele repair; local bupivacaine wound infusion is an important adjunct to reduce opioid use postoperatively.

Current and Future Surgical and Interventional Management Options for Adenomyosis.

Historically, hysterectomy has been the recommended treatment for patients with adenomyosis. However, in the past two decades, various uterine-sparing treatment methods have emerged. These range from excisional techniques such as adenomyomectomy or wedge resection to uterine artery embolization, radiofrequency thermal ablation, hysteroscopic excision, endometrial ablation, and high-intensity focused ultrasound. While largely investigative for the treatment of adenomyosis, these procedures have demonstrated improvement in symptoms including abnormal uterine bleeding, dysmenorrhea, pelvic pain, and overall quality of life. However, long-term data including fertility and obstetric outcomes are needed. Future research is needed to better understand the impact of these uterine-preserving techniques to expand our armamentarium for the treatment of adenomyosis.

Maternal Amino Acid Profiles to Distinguish Constitutionally Small versus Growth-Restricted Fetuses Defined by Doppler Ultrasound: A Pilot Study.

OBJECTIVE: Fetuses measuring below the 10th percentile for gestational age may be either constitutionally small for gestational age (SGA) or have pathologic fetal growth restriction (FGR). FGR is associated with adverse outcomes; however, identification of low-risk SGA cases is difficult. We performed a pilot study evaluating maternal markers of pathologic FGR, hypothesizing there are distinct amino acid signatures that might be used for diagnosis and development of new interventions. STUDY DESIGN: This was a cohort study of healthy women with sonographic fetal estimated fetal weight <5th percentile divided into two groups based upon umbilical artery (UmA) Doppler studies or uterine artery (UtA) Doppler studies. We collected maternal blood samples prior to delivery and used ion pair reverse phase liquid chromatography-mass spectrometry or gas chromatography-mass spectrometry to assess 44 amino acids. RESULTS: Among 14 women included, five had abnormal UmA, and three had abnormal UtA Doppler results. Those with abnormal UmA showed elevated ornithine. Those with abnormal UtA had lower dimethylglycine, isoleucine, methionine, phenylalanine, and 1-methylhistidine. CONCLUSION: We found several amino acids that might identify pregnancies affected by pathologic FGR. These findings support the feasibility of future larger studies to identify maternal metabolic approaches to accurately stratify risk for small fetuses.

Improvised vs Standard Cervical Collar to Restrict Spine Movement in the Backcountry Environment.

INTRODUCTION: To compare the effectiveness of a molded fleece jacket with that of a standard cervical collar at limiting movement of the cervical spine in 3 different directions. METHODS: This is a prospective study using 24 healthy volunteers to measure cervical flexion/extension, rotation, and lateral flexion with both the fleece collar and the standard cervical collar. A hand-held goniometer was used for measurements. The results were then analyzed for the 3 independent movements using a noninferiority test. RESULTS: The fleece collar was determined to be noninferior at limiting the designated motions. Comfort was greater while wearing the improvised fleece collar. CONCLUSIONS: Our small study demonstrated that mountain travelers and rescuers may be able to use an improvised fleece jacket collar in place of a standard collar if spine trauma is suspected after a backcountry accident. Further research should examine different types of improvised collars, their ability to remain in place over extended evacuations, and when to apply collars to backcountry patients.

"I feel like their relationship is based on the media": Relationship Between Media Representation and Adolescents' Relationship Knowledge and Expectations.

Teen dating violence (TDV) is a serious public health issue associated with negative physical and behavior outcomes that disproportionately impact African-American adolescents. Despite the emergence of effective TDV prevention strategies, more knowledge is needed about how African American adolescents understand healthy and unhealthy relationships. Adolescents' analysis of media representations can provide important insight into social norms around adolescent romantic relationships, which can inform the development of TDV prevention strategies. We conducted nine focus groups (n = 86) to explore perceptions of healthy and unhealthy relationships and the influence of media representations on romantic relationships. We transcribed focus group interviews verbatim and coded them line by line. Participants were primarily African American (90%), female (67%), and high school aged (13-17 years). Consistent with other studies, participants reported significant engagement across traditional and social media platforms that exposed them to a wide variety of fictional, celebrity, and peer relationships. A modified constructivist grounded theory analytic approach produced four major relationship themes: commitment, authenticity, privacy, and maturity. These themes captured participants' reflections about romantic relationships and how the media interact with relationship processes and perceptions. Results show that adolescents are using media representations of romantic couples to clarify their own romantic relationship expectations and desires. Future prevention strategies should support youths' use of critical thinking, perspective taking, and analysis to help align their relationship choices and expectations with their own values and preferences.

Mass lesions of the myometrium: interpretation and management of unexpected pathology.

PURPOSE OF REVIEW: Uterine leiomyomas are the most common benign uterine smooth muscle tumors. On the basis of imaging, these masses are often presumed to be benign conventional leiomyomas and surgical excision is a common treatment choice. After myomectomy or hysterectomy for presumed leiomyomas, the surgical pathology report may reveal an unexpected diagnosis of another type of mesenchymal tumor. These can range from a variant of benign smooth muscle tumors to smooth muscle tumors of uncertain malignant potential to malignant sarcomas. This review describes these variant pathologies and reviews data on recurrence risk and postoperative management. RECENT FINDINGS: The majority of benign smooth muscle tumors will be classified as leiomyomas. Cellular, bizarre nuclei, mitotically active, epitheliod, myxoid, and dissecting are all terms that describe pathologic variants of benign leiomyomas. Smooth muscle tumors of uncertain malignant potential contain both benign and malignant features and should be referred to Gynecologic Oncology for follow-up. Leiomyosarcomas and low-grade endometrial stromal sarcomas may present preoperatively as benign tumors but are malignant with a high risk of recurrence and should be referred to Gynecologic Oncology. SUMMARY: We advocate for the continued benefits of minimally invasive procedures in appropriately selected patients. Despite these measures, unexpected pathologic diagnoses can occur and should be managed appropriately.

Video Games and Stress: How Stress Appraisals and Game Content Affect Cardiovascular and Emotion Outcomes.

Although previous studies have found that video games induce stress, studies have not typically measured all salient indicators of stress responses including stress appraisals, cardiovascular indicators, and emotion outcomes. The current study used the Biopsychosocial Model of Challenge and Threat (Blascovich and Tomaka, 1996) to determine if video games induce a cardiovascular stress response by comparing the effects of threat and challenge appraisals across two types of video games that have shown different cardiovascular outcomes. Participants received challenge or threat appraisal instructions, and played a fighting game (Mortal Kombat) or a puzzle game (Tetris). Study outcomes were heart rate variability, systolic and diastolic blood pressure, and positive and negative emotion ratings measured before, during and after gameplay. Results indicated that threat appraisal instructions increased negative emotion ratings and decreased heart rate variability, but not blood pressure, which is an essential marker for cardiovascular stress responses. Increased blood pressure and decreased heart rate variability was associated with fighting game players when compared with the puzzle game players, indicating a cardiovascular stress response; however, fighting game players also reported higher positive emotion ratings. Based on the study findings, video games do not induce stress responses like mental stressors used in previous research, demonstrating that the interactive player experience in video gaming may have more complex effects on stress outcomes. Future research should comprehensively measure biopsychosocial stress indicators and multiple emotional states over time to fully examine the relationship between video games and stress.

Gamers' insights into the phenomenology of normal gaming and game "addiction": A mixed methods study.

In response to calls for further research into the phenomenology of Internet gaming disorder (IGD), we used a community-engaged consensus development approach to evaluate how members of the "gamer culture" describe problematic gaming and the relationship of these descriptions to the proposed IGD criteria. Two focus groups of gamers were recruited at a video game convention. Participants were asked to submit suggestions for signs of game "addiction". Participants discussed and ranked the criteria in order of conceptual importance. The rankings were analyzed quantitatively, and then a multidisciplinary team compared the ranked criteria to the DSM-5 IGD proposed criteria. The strongest agreement between participants' rankings and IGD symptomatology was found for harms/functional impairment due to gaming, continued use despite problems, unsuccessful attempts to control gaming, and loss of interest in previous hobbies and entertainment. There was less support for other IGD criteria. Participants also offered new content domains. These findings suggest that collaborative knowledge-building approaches may help researchers and policymakers understand the characteristics and processes specific to problematic video game play and improve content validity of IGD criteria. Future efforts may benefit from multi-stakeholder approaches to refine IGD criteria and inform theory, measurement and intervention.

Fetal Sex Differences in Intrapartum Electronic Fetal Monitoring.

Objective The article aimed to estimate differences in electronic fetal monitoring (EFM) patterns in term gestations attributable to fetal sex. Study Design We conducted a prospective cohort study of consecutive, singleton, nonanomalous, term gestations that labored during admission. EFM characteristics in the 30 minutes prior to delivery were evaluated. Logistic regression models estimated adjusted risks for EFM features by sex. To further estimate the impact of sex, we limited the analysis to gestations without composite morbidity (morbidity defined as arterial cord pH <7.20, 5-minute Apgar <7, or neonatal intensive care unit admission). Results Of 2,639 deliveries, 1,400 (53%) were male. Male fetuses had a higher number of decelerations (median [interquartile range]: 8 [5, 11] vs. 7 [4, 10], p < 0.003) and increased total deceleration area (adjusted odds ratio [aOR]: 1.11, 95% confidence interval [CI] :1.04, 1.18). Male fetuses were at increased risk for prolonged decelerations (aOR: 1.21, 95% CI: 1.03, 1.42) and repetitive variable decelerations (aOR: 1.24, 95% CI: 1.05, 1.47). Among neonates without composite morbidity (n = 2,446, 92.7%), male sex conferred an increased risk of late decelerations (aOR: 1.21, 95% CI: 1.02, 1.43) and increased total deceleration area (aOR: 1.12, 95% CI: 1.05, 1.20). Conclusion There are significant sex differences in EFM patterns at term among pregnancies without evidence of acidemia. This suggests that interpretation of EFM patterns may need to take into account factors such as fetal sex.

Uncontained Compared With Contained Power Morcellation in Total Laparoscopic Hysterectomy.

OBJECTIVE: To compare perioperative outcomes of uncontained and contained power morcellation in total laparoscopic hysterectomy. METHODS: Women who underwent total laparoscopic hysterectomy that required utilization of power morcellation between July 2012 and January 2015 in the Division of Minimally Invasive Gynecology at an academic tertiary care center were included. In February 2014, the division began performing all power morcellation contained within a large insufflated bag in an attempt to reduce dissemination of benign and malignant uterine tissue. Data were collected from a prospective database and analyzed as a retrospective cohort. The primary outcome was operative time. Secondary outcomes included estimated blood loss, length of stay, pathology, uterine weight, and complications, including blood transfusion, conversion to open, intraoperative organ injury, pelvic infection, readmission, or reoperation. RESULTS: A total of 152 patients were identified: 101 uncontained morcellations and 51 contained morcellations. The baseline demographic characteristics between the two groups were similar. Operative time was longer in the contained morcellation group (184 compared with 164 minutes, P=.01). There were no cases of visible bag disruption or dissemination of uterine tissue in the contained morcellation group. CONCLUSION: Contained power morcellation at the time of total laparoscopic hysterectomy is associated with a 20-minute increase in operative time when compared with uncontained morcellation. LEVEL OF EVIDENCE: II.

Target categorization with primes that vary in both congruency and sense modality.

In two experiments we examined conceptual priming within and across sense modalities by varying the modality (picture and environmental sounds) and the category congruency of prime-target pairs. Both experiments used a repetition priming paradigm, but Experiment 1 studied priming effects with a task that required a superordinate categorization response (man-made or natural), while Experiment 2 used a lower level category response (musical instruments or animal): one that was more closely associated with the basic level of the semantic network. Results from Experiment 1 showed a strong effect of target modality and two distinct patterns of conceptual priming effects with picture and environmental sound targets. However, no priming advantage was found when congruent and incongruent primes were compared. Results from Experiment 2, found congruency effects that were specific to environmental sound targets when preceded by picture primes. The findings provide support for the intermodal event file and multisensory framework, and suggest that auditory and visual features about a single item in a conceptual category may be more tightly connected than two different items from the same category.

Conceptual priming with pictures and environmental sounds.

A series of experiments was conducted to examine conceptual priming within and across modalities with pictures and environmental sounds. In Experiment 1, we developed a new multimodal stimulus set consisting of two picture and sound exemplars that represented 80 object items. In Experiments 2, we investigated whether categorization of the stimulus items would be facilitated by picture and environmental sound primes that were derived from different exemplars of the target items; and in Experiments 3 and 4, we tested the additional influence on priming when trials were consolidated within a target modality and the inter stimulus interval was lengthened. The results demonstrated that target categorization was facilitated by the advanced presentation of conceptually related exemplars, but there were differences in effectiveness when pictures and sounds appeared as primes.

Hospitalist-orthopedic co-management of high-risk patients undergoing lower extremity reconstruction surgery.

The introduction of the hospitalist co-management model represents an opportunity to improve care by changing the system as it applies to a small group of patients. Eighty-six consecutive patients with multiple comorbidities were selectively enrolled in an academic medical center hospitalist-orthopedic surgery co-management patient care program. Patients were stratified by all patient refined diagnosis-related groups, severity of illness, and risk of mortality. Hospital length of stay, cost of care, in-hospital mortality, complications, and intensive care unit admissions were compared with a retrospectively constructed control group of 54 patients undergoing similar surgery during the period immediately preceding initiation of the program. The University Health System Consortium observed-to-expected ratio for hospital length of stay was 0.693 compared to 0.862 for the control group. The severity of illness and risk of mortality scores represented a relatively higher risk stratification in the study group. While the overall observed-to-expected cost of care remained virtually unchanged, the positive impact of the study model revealed an increased positive effect on the more severely affected severity of illness and risk of mortality patients. The results of this study suggest that a proactive, cooperative, co-management model for the perioperative management of high-risk patients undergoing complex surgery can improve the quality and efficiency metrics associated with the delivery of service to patients.

The MTHFR 677C-->T polymorphism and behaviors in children with autism: exploratory genotype-phenotype correlations.

New evidence suggests that autism may be associated with (a) varied behavioral responses to folate therapy and (b) metabolic anomalies, including those in folate metabolism, that contribute to hypomethylation of DNA. We hypothesized that children with autism who are homozygous for the MTHFR 677 T allele (TT) and, to a lesser extent those with the CT variant, would exhibit more behavioral problems and/or more severe problematic behaviors than homozygous wild-type (CC) individuals because of difficulties in effectively converting 5,10-MTHF to 5-MTHF. Data from the Autism Genetic Resource Exchange (AGRE) collection were analyzed for all children who met strict criteria for autism per the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) and who had been genotyped for the 677 C to T MTHFR polymorphism (n=147). Chi-square tests, logistic regression, and one-way ANOVAs were used to determine whether differences existed among MTHFR genotypes for specific behaviors on the ADI-R and indices for level of functioning. Exploratory results indicated four behaviors from the ADI-R that were more common and problematic (95% CI) among those with at least one copy of the T allele as compared to homozygous wild-type individuals: direct gaze, current complex body movements, a history of self-injurious behavior, and current overactivity (ORs=2.72, 2.33, 2.12, 2.47, respectively). No differences existed among genotypes for level of functioning as measured with the Peabody Picture Vocabulary Test-Third Edition, Ravens Colored Progressive Matrices, or the Vineland Adaptive Behavior Scales. Findings call for further investigation of the relationship between folate metabolism and problem behaviors among children with autism.

Template-guided versus undirected written medical documentation: a prospective, randomized trial in a family medicine residency clinic.

PURPOSE: To compare a template-driven medical documentation system to undirected handwritten documentation and determine whether the template (1) decreases physician evaluation time, (2) increases gross billing, and (3) increases physician satisfaction with the documentation process. METHODS: A prospective randomized trial of documentation with a template system (T-System for Primary Care, Dallas, TX) versus undirected handwritten documentation was conducted in 2 separate teams of a single family medicine residency program. After training, one team used the template system and the other team used undirected written documentation. Clinic visit duration was recorded. Medical records were evaluated by a blinded professional coder to assign an evaluation/management code. Clinic visit duration and coding level differences were evaluated using an independent t test. At the conclusion of the study, residents completed a questionnaire to determine physician satisfaction with the documentation tool. Survey responses were on a -2 to + 2 Likert scale. Means and standard deviations are reported. RESULTS: A total of 1339 patients were included in the analysis of patient visits. There was no significant difference in clinic time between the template system and the written documentation visits. The mean visit time was 1.75 hours for both teams. For the analysis of gross billing, 1237 charts were included. The mean billing amount for written documentation was USD $150 and for the template system it was USD $163--a statistically significant difference. The physicians' surveys favored continuing to use the template documentation method. CONCLUSIONS: The template medical documentation system compared with undirected written documentation produced a significantly higher bill for the visit, yielding no differences in evaluation time, and was overall positively received by the residents and faculty.
