The role of digital examination in the setting of a sonographically short cervix.

BACKGROUND: Universal transvaginal cervical length screening has been associated with a reduction in the frequency of preterm birth. However, there is no clinically set standard to guide the performance of a digital cervical examination in the setting of a sonographically short cervix. OBJECTIVE: To investigate the prevalence of cervical dilation at various midtrimester transvaginal cervical length thresholds. Furthermore, we sought to identify sonographic or clinical characteristics associated with cervical dilation that may inform who would benefit from a digital cervical examination in the setting of a sonographically short cervix. STUDY DESIGN: This retrospective cohort study was conducted at an academic institution and included women with a singleton gestation and an ultrasonographically detected short cervix (defined as a transvaginally obtained cervical length ≤25 mm) who had a documented digital cervical examination within 1 week of the ultrasonography. Bivariable analyses were used to determine the relationship between cervical length and the presence of cervical dilation. Multivariable logistic regression and receiver operating characteristic curve were used to evaluate the relationship between clinical and sonographic risk factors and cervical dilation. RESULTS: Of the 256 women who met eligibility criteria and had a sonographically detected short cervix, 103 (40.2%) were found to be dilated on digital cervical examination. The prevalence of cervical dilation increased as sonographic cervical length decreased; cervical dilation was identified in 15%, 39%, 53%, 64%, and 69% of women with a cervical length between 20.0 and 25.0 mm, 15.0 and 19.9 mm, 10.0 and 14.9 mm, 5.0 and 9.9 mm, and 0.0 and 4.9 mm, respectively. Maternal race or ethnicity (examined as a social construct), insurance status, nulliparity, previous cervical excisional procedure, funneling on ultrasonography, and sonographic cervical length were each associated with cervical dilation. However, including all of these variables into a regression yielded a model with only moderate predictive ability to identify cervical dilation, with receiver operating area under the curve of 0.77 (95% confidence interval, 0.71-0.83). CONCLUSION: Consideration should be given to performing a digital cervical examination in the setting of a sonographically short cervix (especially <20 mm) to detect cervical dilation.

Association between quality of life and patient-reported complications from surgery and radioiodine in early-stage thyroid cancer survivors: A matched-pair analysis.

BACKGROUND: Remnant radioiodine ablation is discouraged in low-risk differentiated thyroid cancer because it confers no survival advantage. The impact of remnant radioiodine ablation on health-related quality of life in these patients is not well described. We hypothesized remnant radioiodine ablation is associated with lower health-related quality of life in early-stage differentiated thyroid cancer survivors. METHODS: A retrospective matched-pair analysis was conducted in stage I differentiated thyroid cancer survivors recruited from a thyroid cancer support group. Respondents self-reported via online survey. Dysphonia and dysphagia were reported via Likert scale. Health-related quality of life was evaluated using Patient-Reported Outcomes Measurement Information System (PROMIS) 29-item profile. Respondents who received remnant radioiodine ablation were matched for age, sex, race, and years since diagnosis with respondents who did not receive remnant radioiodine ablation. PROMIS t-scores were compared between remnant radioiodine ablation and nonremnant radioiodine ablation groups, and among those with or without surgical complications. RESULTS: One hundred and twenty-two pairs were matched. There was no significant difference in incidence of self-reported hypocalcemia, infection, dysphonia, or dysphagia between remnant radioiodine ablation and no remnant radioiodine ablation groups. There was no significant difference in mean PROMIS t-scores. Of respondents reporting normal preoperative voice and swallowing, there were no significant differences in postprocedural outcomes or PROMIS scores. Regardless of remnant radioiodine ablation treatment, those with surgical complications of hypocalcemia, dysphonia, or dysphagia reported worse PROMIS scores across multiple domains. Remnant radioiodine ablation-associated xerostomia was associated with worse PROMIS scores across multiple domains. CONCLUSION: This is the first study to use PROMIS measures to evaluate the association between remnant radioiodine ablation and health-related quality of life in early-stage differentiated thyroid cancer survivors treated surgically. Surgical and remnant radioiodine ablation-associated complications were associated with significantly worse PROMIS scores across multiple domains.

Improving cardiology fellow education of right heart catheterization using a simulation based curriculum.

BACKGROUND: Medical procedures are traditionally taught informally at patients' bedside through observation and practice using the adage "see one, do one, teach one." This lack of formalized training can cause trainees to be unprepared to perform procedures independently. Simulation based education (SBE) increases competence, reduces complications, and decreases costs. We developed, implemented, and evaluated the efficacy of a right heart catheterization (RHC) SBE curriculum. METHODS: The RHC curriculum consisted of a pretest, video didactics, deliberate practice, and a posttest. Pre-and posttest skills examinations consisted of a dichotomous 43-item checklist on RHC skills and a 14-item hemodynamic waveform quiz. We enrolled two groups of fellows: 6 first-year, novice cardiology fellows at Northwestern University in their first month of training, and 11 second- and third-year fellows who had completed traditional required, level I training in RHC. We trained the first-year fellows at the beginning of the 2018-2019 year using the SBE curriculum and compared them to the traditionally-trained cardiology fellows who did not complete SBE. RESULTS: The SBE-trained fellows significantly improved RHC skills, hemodynamic knowledge, and confidence from pre- to posttesting. SBE-trained fellows performed similarly to traditionally-trained fellows on simulated RHC skills checklists (88.4% correct vs. 89.2%, p = .84), hemodynamic quizzes (94.0% correct vs. 86.4%, p = .12), and confidence (79.4 vs. 85.9 out of 100, p = .15) despite less clinical experience. CONCLUSIONS: A SBE curriculum for RHC allowed novice cardiology fellows to achieve level I skills and knowledge at the beginning of fellowship and can train cardiology fellows before patient contact.
