Objective Determine whether the patient-identified minimum important difference (MID) in Nasal Obstruction Symptom Evaluation (NOSE) score differs from a statistically calculated estimate of MID in patients with septal deviation undergoing nasal airway surgery. Study Design Prospective cohort. Setting Tertiary academic referral center. Subjects Patients with nasal obstruction due to septal deviation. Methods Patients completed the NOSE questionnaire preoperatively and indicated the change from their baseline score that they would consider the minimum improvement required to define the septoplasty with turbinate reduction as successful. A previously published distribution-based approach was used to estimate the MID based on baseline NOSE scores. Scores were reported both as a raw score and as a percentage of patients' baseline scores. One-sample t test was used to compare the statistically estimated MID to the patient-reported MID. Results Seventy-six patients were included. The mean (SD) baseline NOSE score was 12.9 (4.03). The mean (SD) patient-identified MID was 5.3 (2.1), corresponding to a 41.1% change (95% confidence interval, 37.2-41.3) from baseline. The statistically estimated MID was 5.2 points (40.3% reduction from baseline scores). The estimated MID was not significantly different from the patient-identified MID ( P = .4). Conclusion In patients with septal deviation, an improvement of approximately 40% in their nasal obstructive symptoms as assessed by the NOSE questionnaire is required to define a nasal airway surgery as successful. The patient-identified and the statistically calculated MIDs were similar. Furthermore, this MID can be used to guide research, improving the ability to use the NOSE score as a dichotomous scoring measure (treatment success/failure) and estimating sample size.
BackgroundPlate-related complications following head and neck cancer ablation and reconstruction remains a challenging problem often requiring further management and reconstructive surgeries. We aim to identify an association between surgical site infections (SSI) and plate exposure.MethodsA retrospective study between 1997 and 2014 was performed to study the association between postoperative SSI and plate exposures. Eligible patients included those with a history of oral squamous cell carcinoma who underwent surgical resection, neck dissection, and free tissue reconstruction. Demographic and treatment related information was collected. SSI were classified based on CDC definition and previously published literature. Univariable analysis on demographic factors, smoking history, diabetes, radiation, surgical and hardware related factors; while multivariable analysis on SSI, plate height, segmental mandibulectomy defects and radiation were conducted such as using cox proportional hazard models.ResultsThree hundred sixty-five patients were identified and included in our study. The mean age of the study group was 59.2 (+/−13.8), with a predominance of male patients (61.9%). 10.7% of our patient cohort had diabetes, and another 63.8% had post-operative radiation therapy. Patients with SSI were more likely to have plate exposure (25 vs. 6.4%, p <0.001). Post-operative SSI, mandibulectomy defects, and plate profile/thickness were associated with plate exposure on univariable analysis (OR = 5.72, p < 0.001; OR = 2.56, p = 0.014; OR = 1.44, p = 0.003 respectively) and multivariable analysis (OR = 5.13, p < 0.001; OR = 1.36, p = 0.017; OR = 2.58, p = 0.02 respectively).ConclusionSurgical site infections are associated with higher rates of plate exposure. Plate exposure may require multiple procedures to manage and occasionally free flap reconstruction.
Objective: To evaluate multilevel palate and tongue base surgery as a method of treatment of obstructive sleep apnea by comparing the pre-and postoperative apnea-hypopnea index.Methods: We conducted a systematic review. MEDLINE and Embase databases were searched in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for conducting systematic reviews. Two authors screened all articles and performed methodological quality assessment. Relevant articles where reviewed in detail. Standard inclusion criteria were applied for article selection. Relevant data were extracted and summarized, a difference of means random-effects model was performed. Our primary outcome measure was change in apnea-hypopnea index pre-/postsurgical treatment.Results: Of 1,172 studies identified from January 2006 to March 2017, 46 studies met inclusion criteria and were included in the systematic review. This included 11 surgical subgroups and 1,806 patients. Methodological quality and risk of bias assessments were completed. There was strong male predominance 86.8 (standard deviation [SD] = 10.3%), and the average age was 46.8 (SD = 4.0) years. All studies included overweight to obese patients (average body mass index = 29.1 [SD = 3.5]). The average preoperative apnea-hypopnea index was 39.0 (SD = 15.4), and the average postoperative apnea-hypopnea index decreased to 18.3 (SD = 7.5). Meta-analysis data yielded a decrease in apnea-hypopnea index of −23.67 with a 95% confidence interval of −27.27 to −20.06.Conclusions: Non-maxillomandibular advancement, multilevel surgical procedures for obstructive sleep apnea demonstrate significant improvements in reduction of apnea-hypopnea index following surgery in addition to improvement in many other sleep-specific outcomes. Future research should include larger, higher-level studies that compare surgical treatments and identify factors associated with outcomes.Key Words: Obstructive sleep apnea, surgical treatment of obstructive sleep apnea, sleep medicine, sleep apnea, quality of life.
ObjectivesWe audited a selection of systematic reviews published in 2013 and reported on the proportion of reviews that researched for unpublished data, included unpublished data in analysis and assessed for publication bias.DesignAudit of systematic reviews.Data sourcesWe searched PubMed and Ovid MEDLINE In-Process & Other Non-Indexed Citations between 1 January 2013 and 31 December 2013 for the following journals: Journal of the American Medical Association, The British Medical Journal, Lancet, Annals of Internal Medicine and the Cochrane Database of Systematic Reviews. We also searched the Cochrane Library and included 100 randomly selected Cochrane reviews.Eligibility criteriaSystematic reviews published in 2013 in the selected journals were included. Methodological reviews were excluded.Data extraction and synthesisTwo reviewers independently reviewed each included systematic review. The following data were extracted: whether the review searched for grey literature or unpublished data, the sources searched, whether unpublished data were included in analysis, whether publication bias was assessed and whether there was evidence of publication bias.Main findings203 reviews were included for analysis. 36% (73/203) of studies did not describe any attempt to obtain unpublished studies or to search grey literature. 89% (116/130) of studies that sought unpublished data found them. 33% (68/203) of studies included an assessment of publication bias, and 40% (27/68) of these found evidence of publication bias.ConclusionA significant fraction of systematic reviews included in our study did not search for unpublished data. Publication bias may be present in almost half the published systematic reviews that assessed for it. Exclusion of unpublished data may lead to biased estimates of efficacy or safety in systematic reviews.
IMPORTANCEAlthough most thyroid nodules are benign, the potential for malignant neoplasms is associated with unnecessary workup in the form of imaging, fine-needle aspiration, and diagnostic surgery. The American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS) is commonly used to assess the malignant neoplasm risk potential of thyroid nodules imaged by ultrasonography. However, standardized reporting of ACR TI-RADS descriptors is inconsistent.OBJECTIVE To increase the documentation rate of ACR TI-RADS thyroid nodule characteristics to 80% in 18 months. DESIGN, SETTING, AND PARTICIPANTSThis prospective interrupted time series quality improvement study was conducted from December 1, 2018, to March 31, 2020, at a tertiary outpatient head and neck clinic among 229 patients who had at least 1 documented thyroid nodule identified on bedside clinic ultrasonography. Data analysis was performed throughout the entire study period because this was a quality improvement study with iterative small cycle changes; final analysis of the data was performed in April 2020. MAIN OUTCOMES AND MEASURESThe primary outcome was the documentation rates of 6 ACR TI-RADS ultrasonographic descriptors. Secondary outcomes included nodule fine-needle aspiration biopsy rate and physician-reported clinic flow efficiency.RESULTS A total of 229 patients had at least 1 documented thyroid nodule and were included in the analysis. Size was the most frequently documented nodule characteristic (72 of 74 [97.3%]) at baseline, followed by echogenic foci (31 of 74 [41.9%]), composition (23 of 74 [31.1%]), echogenicity (17 of 74 [23.0%]), margin (6 of 74 [8.1%]), and shape (1 of 74 [1.4%]). After 3 Plan, Do, Study, Act (PDSA) cycles, the final intervention consisted of a standardized ultrasonography reporting form and educational initiatives for surgical trainees. After the third PDSA cycle (n = 36), reporting of nodule size, echogenic foci, and composition increased to 100%. Similarly, reporting of echogenicity (34 of 36 [94.4%]), shape (28 of 36 [77.8%]), and margin (25 of 36 [69.4%]) all increased. This represented a cumulative 90.3% documentation rate (195 of 216), a 56.5% increase from baseline (95% CI, 50.0%-61.9%). The standardized reporting form was used in 83.3% of eligible thyroid ultrasonography cases (30 of 36) after PDSA cycle 3, demonstrating good fidelity of implementation. There were no unintended consequences associated with clinic workflow, as a balancing measure, reported by staff surgeons.CONCLUSIONS AND RELEVANCE This study suggests that implementation of an ACR TI-RADS-based reporting form in conjunction with educational initiatives improved documentation of ultrasonographic thyroid nodule characteristics, potentially allowing for improved bedside risk stratification and communication among clinicians.
