Development and validation of a patient-reported scale for tolerability of endoscopic procedures using conscious sedation.
Ontology highlight
ABSTRACT: Background and aims
Patient-reported experience measures (PREMs) assessing the tolerability of endoscopic procedures are scarce. In this study, we designed and validated a PREM to assess tolerability of endoscopy using conscious sedation.Methods
The patient-reported scale for tolerability of endoscopic procedures (PRO-STEP) consists of questions within 2 domains and is administered to outpatients at discharge from the endoscopy unit. Domain 1 (intraprocedural) consists of 2 questions regarding discomfort/pain and awareness, whereas domain 2 (postprocedural) consists of 4 questions on pain, nausea, distention, and either throat or anal pain. All questions are scored on a Likert scale from 0 to 10. Cronbach's alpha was used to measure internal consistency of the questions. Multivariable logistic regression was performed to assess predictors of higher scores, reported using adjusted odds ratios and confidence intervals.Results
Two hundred fifty-five patients (91 colonoscopy, 73 gastroscopy, and 91 ERCP) were included. Colonoscopy was the least tolerable procedure by recall, with mean intraprocedural awareness and discomfort scores of 5.1 ± 3.8, and 2.6 ± 2.7, respectively. Consistency between intraprocedural awareness and discomfort/pain yielded an acceptable Cronbach's alpha of .71 (95% confidence interval, .62-.78). Higher use of midazolam during colonoscopy was inversely associated with an intraprocedural awareness score of 7 or higher (per additional mg: adjusted odds ratio, .23; 95% confidence interval, .09-.54).Conclusions
PRO-STEP is a simple PREM that can be administered after multiple endoscopic procedures using conscious sedation. Future work should focus on its performance characteristics in adverse event prediction.

Project description:Objective: To validate a patient-reported outcome (PRO) measure for patients with tension-type headache (TTH). Methods: Literature analysis, interview, and group discussion were performed to develop an initial TTH-PRO. Thereafter, the initial scale was pre-evaluation in a small range of patients with TTH, and the expert panel made necessary adjustments based on the content feedback. The clinical test was carried out by using the adjusted initial scale. Based on the test results, the items were screened by the method of classical test theory to form the final scale, and the performance evaluation indicators such as validity, reliability, and responsiveness of the final scale were tested. Results: The final formed TTH-PRO scale contained three domains, six dimensions, and 30 items. The split-half reliability, Cronbach's α coefficients, and construct validity of the scale were acceptable, as was feasibility. The responsiveness in the physiological domain was fair, but the overall responsiveness still needed further clinical validation. Conclusions:The TTH-PRO scale has been developed with extensive patient input and demonstrates evidence for reliability and validity. It is complementary to existing evaluation indicators of TTH, emphasizing the patient's experience. Further studies are needed to optimize its items and to verify its clinical applicability for population in more regions and countries.

Project description:The lack of standardization of sedation scales in horses limits the reproducibility between different studies. This prospective, randomized, blinded, horizontal and controlled trial aimed to validate a scale for sedation in horses (EquiSed). Seven horses were treated with intravenous detomidine in low/high doses alone (DL 2.5 μg/kg + 6.25 μg/kg/h; DH 5 μg/kg +12.5 μg/kg/h) or associated with methadone (DLM and DHM, 0.2 mg/kg + 0.05 mg/kg/h) and with low (ACPL 0.02 mg/kg) or high (ACPH 0.09 mg/kg) doses of acepromazine alone. Horses were filmed at (i) baseline (ii) peak, (iii) intermediate, and (iv) end of sedation immediately before auditory, visual and pressure stimuli were applied and postural instability evaluated for another study. Videos were randomized and blindly evaluated by four evaluators in two phases with 1-month interval. Intra- and interobserver reliability of the sum of EquiSed (Intraclass correlation coefficient) ranged between 0.84-0.94 and 0.45-0.88, respectively. The criterion validity was endorsed by the high Spearman correlation between the EquiSed and visual analog (0.77), numerical rating (0.76), and simple descriptive scales (0.70), and average correlation with head height above the ground (HHAG) (-0.52). The Friedman test confirmed the EquiSed responsiveness over time. The principal component analysis showed that all items of the scale had a load factor ≥ 0.50. The item-total Spearman correlation for all items ranged from 0.3 to 0.5, and the internal consistency was good (Cronbach's α = 0.73). The area under the curve of EquiSed HHAG as a predictive diagnostic measure was 0.88. The sensitivity of the EquiSed calculated according to the cut-off point (score 7 of the sum of the EquiSed) determined by the receiver operating characteristic curve, was 96% and specificity was 83%. EquiSed has good intra- and interobserver reliabilities and is valid to evaluate tranquilization and sedation in horses.

Project description:ObjectivesDevelopment and validation of the Pediatric Sedation State Scale (PSSS) is intended to specifically meet the needs of pediatric procedural sedation providers to measure effectiveness and quality of care.MethodsThe PSSS content was developed through Delphi methods utilizing leading pediatric sedation experts and published guidelines on procedural sedation in children. Video clips were created and presented to study participants, who graded the state of patients during procedures by using the PSSS to evaluate inter- and intrarater reliability by determining the intraclass correlation coefficient. We also compared the PSSS to the Observational Scale of Behavioral Distress-revised during 4 clinically relevant phases of a laceration repair procedure.ResultsSix sedation states were defined for the PSSS. Each state was assigned a numerical value with higher numbers for increasing activity states. We included behaviors associated with adequate and inadequate sedation and adverse events associated with excessive sedation. Analysis of interrater and intrarater reliability revealed an intraclass correlation coefficient of 0.994 (95% confidence interval: 0.986-0.998) and 0.986 (95% confidence interval: 0.970-0.995), respectively. Criterion validity was confirmed with respect to the Observational Scale of Behavioral Distress-revised (Spearman r = 0.96). Construct validity was indicated by significant differences in PSSS scores (P < .001) between 4 phases of a procedure, each having a different degree of painful or distressing stimuli.ConclusionsThe PSSS is a 6-point scale that is a valid measure of the effectiveness and quality of procedural sedation in children within the limits of the testing method used in this study.

Project description:Although facial characteristics are used to estimate horse sedation, there are no studies measuring their reliability and validity. This randomised controlled, prospective, horizontal study aimed to validate a facial sedation scale for horses (FaceSed). Seven horses received detomidine infusion i.v. in low or high doses/rates alone (DL 2.5 μg/kg+6.25 μg/kg/h; DH 5 μg/kg+12.5 μg/kg/h) or combined with methadone (DLM and DHM, 0.2 mg/kg+0.05 mg/kg/h) for 120 min, or acepromazine boli i.v. in low (ACPL 0.02 mg/kg) or high doses (ACPH 0.09 mg/kg). Horses' faces were photographed at i) baseline, ii) peak, iii) intermediate, and iv) end of sedation. After randomisation of moments and treatments, photos were sent to four evaluators to assess the FaceSed items (ear position, orbital opening, relaxation of the lower and upper lip) twice, within a one-month interval. The intraclass correlation coefficient of intra- and interobserver reliability of FaceSed scores were good to very good (0.74-0.94) and moderate to very good (0.57-0.87), respectively. Criterion validity based on Spearman correlation between the FaceSed versus the numerical rating scale and head height above the ground were 0.92 and -0.75, respectively. All items and the FaceSed total score showed responsiveness (construct validity). According to the principal component analysis all FaceSed items had load factors >0.50 at the first dimension. The high internal consistency (Cronbach´s α = 0.83) indicated good intercorrelation among items. Item-total Spearman correlation was adequate (rho 0.3-0.73), indicating homogeneity of the scale. All items showed sensitivity (0.82-0.97) to detect sedation, however only orbital opening (0.79) and upper lip relaxation (0.82) were specific to detect absence of sedation. The limitations were that the facial expression was performed using photos, which do not represent the facial movement and the horses were docile, which may have reduced specificity. The FaceSed is a valid and reliable tool to assess tranquilisation and sedation in horses.

Project description:Background Endoscopic procedures are performed commonly with moderate sedation. Obesity can pose a challenge in its safe administration. This study was aimed at assessing outcomes of endoscopy procedures performed with moderate sedation in obese patients. Patients and methods This was a retrospective study of patients undergoing esophagogastroduodenoscopy (EGD) and/or colonoscopy with moderate sedation from July 17, 2017 to December 31, 2019. Demographics, comorbidities, outpatient medications and procedure-related outcomes (procedure time, recovery time, cardiopulmonary adverse events, 7-day post-procedure hospitalization, cecal intubation time, withdrawal time, tolerance of moderate sedation and sedation medications administered) were compared for patient with and without obesity after propensity score matching. Standard statistical methods were used for analysis. Results A total of 7601 procedures were performed with moderate sedation for 5746 patients. Propensity score matching identified 1360 and 1740 pairs of EGDs and colonoscopies with moderate sedation for patients with and without obesity. Recovery time was found to be shorter for obese patients undergoing EGD (OR: 0.989, 95 % CI: 0.981-.998; P = 0.01). Obese patients did not differ from non-obese patients in any other procedure-related outcomes for EGDs or colonoscopies. Conclusions Outcomes for endoscopy procedures performed with moderate sedation were noted to be similar between obese and non-obese patients. These findings suggest that moderate sedation can be used safely for endoscopic procedures in patients with obesity.

Project description:BACKGROUND:Propofol sedation is effective for gastrointestinal endoscopic procedures, but its narrow therapeutic window highlights the importance of identifying an optimal administration technique regarding effectiveness and safety. This study aimed to determine the incidence of significant adverse events in adult patients scheduled for gastrointestinal endoscopy under anaesthetist-performed sedation using propofol target-controlled infusion and determine the existence of associations between these events and potentially related variables. METHODS:This single-centre, retrospective cohort study took place in a tertiary referral university hospital. Medical records of 823 patients (age?>?18?years, American Society of Anesthesiologists physical status classification scores I-III) who had undergone elective gastrointestinal endoscopy under propofol target-controlled infusion sedation during September 2018 were reviewed. Outcomes included hypoxia, hypotension, and bradycardia events, requirement of vasoactive drugs, unplanned tracheal intubation or supraglottic device insertion, and need for advanced cardiac life support. RESULTS:The most frequently encountered adverse event was oxygen desaturation <?95% with an incidence of 22.35%. Vasoactive drug administration, hypotension, and oxygen desaturation <?90% followed, with incidences of 19.2, 12.64, and 9.92%, respectively. Only 0.5% of patients required advanced airway management. Multivariate analysis revealed an association between hypotension events, colonoscopic procedures, and propofol doses (odds ratio: 3.08, 95% confidence interval: 1.43 to 6.61; P?=?0.004 and odds ratio: 1.14, 95% confidence interval: 1.00 to 1.29; P?=?0.046). A strong dose-effect relationship was found between hypoxia and obesity; patients with body mass index ?40 were nine times (odds ratio: 10.22, 95% confidence interval: 2.83 to 36.99) more likely to experience oxygen desaturation <?90% events. CONCLUSIONS:Propofol sedation using target-controlled infusion appears to be a safe and effective anaesthetic technique for gastrointestinal endoscopic procedures with acceptable rates of adverse events and could be more widely adopted in clinical practice.

Project description:Importance:Despite the growing popularity of cosmetic procedures, the sociocultural and quality-of-life factors that motivate patients to undergo such procedures are not well understood. Objective:To estimate the relative importance of factors that motivate patients to seek minimally invasive cosmetic procedures. Design, Setting, and Participants:This prospective, multicenter observational study was performed at 2 academic and 11 private dermatology practice sites that represented all US geographic regions. Adult patients presenting for cosmetic consultation or treatment from December 4, 2016, through August 9, 2017, were eligible for participation. Exposures:Participants completed a survey instrument based on a recently developed subjective framework of motivations and a demographic questionnaire. Main Outcomes and Measures:Primary outcomes were the self-reported most common motivations in each quality-of-life category. Secondary outcomes were other frequently reported motivations and those associated with specific procedures. Results:Of 529 eligible patients, 511 agreed to participate, were enrolled, and completed the survey. Typical respondents were female (440 [86.1%]), 45 years or older (286 [56.0%]), white (386 [75.5%]), and college educated (469 [91.8%]) and had previously received at least 2 cosmetic procedures (270 [52.8%]). Apart from motivations pertaining to aesthetic appearance, including the desire for beautiful skin and a youthful, attractive appearance, motives related to physical health, such as preventing worsening of condition or symptoms (253 of 475 [53.3%]), and psychosocial well-being, such as the desire to feel happier and more confident or improve total quality of life (314 of 467 [67.2%]), treat oneself or celebrate (284 of 463 [61.3%]), and look good professionally (261 of 476 [54.8%]) were commonly reported. Motivations related to cost and convenience were rated as less important (68 of 483 [14.1%]). Most motivations were internally generated, designed to please the patients and not others, with patients making the decision to undergo cosmetic procedures themselves and spouses seldom being influential. Patients younger than 45 years were more likely to undertake procedures to prevent aging (54 of 212 [25.5%] vs 42 of 286 [14.7%] among patients ?45 years; P?<?.001). Patients seeking certain procedures, such as body contouring (19 of 22 [86.4%]), acne scar treatment (36 of 42 [85.7%]), and tattoo removal (8 of 11 [72.7%]), were more likely to report psychological and emotional motivations. Conclusions and Relevance:This initial prospective, multicenter study comprehensively assessed why patients seek minimally invasive cosmetic procedures. Common reasons included emotional, psychological, and practical motivations in addition to the desire to enhance physical appearance. Differences relative to patient age and procedures sought may need further exploration.

Project description:Phase I experts recommend revisiting dose-limiting toxicity (DLT) definition to include chronic and cumulative toxicities induced by new molecularly targeted therapies. Patient's assessment of late toxicities' tolerability is, however, unknown.A prospective survey on adverse events (AEs) tolerability on 23 National Cancer InstituteCommon Terminology Criteria for Adverse Event, Version 4 (NCI-CTCAE.v4) items was conducted at Gustave Roussy's Phase I department. Patients' maximum tolerability duration was recorded at baseline, during trial and at trial completion. Results were compared with the corresponding physicians' survey.52 patients enrolled in 27 Phase I trials between May 2014 and November 2015 completed 102 forms. At baseline, the most feared G2/G3 AEs were haematuria (74%), vomiting (71%) and hyperglycemia (64%)/dry mouth (94%), hyperglycemia (92%) and vomiting (92%). At trial completion, the most feared G2/G3 AEs were personality change (83.3%), haematuria (82%) and fever (80%)/dry mouth, fever and dizziness (100% each). Tolerability score did not differ over time. More previous treatments and occurrence of severe AEs were associated with better tolerability at study completion (p=0.0234 and p=0.0153, respectively, in multivariate analysis). Patient's tolerability differed from physician's assessment.AEs considered intolerable by patients are toxicities that directly impact their quality of life and differ from those feared by physicians or included in DLT definition. Patient-reported tolerability of AEs may help in optimising drug development.

Project description:BACKGROUND:The creation of a single patient-reported outcome (PRO) platform validated across hip preservation, osteoarthritis (OA), and total hip arthroplasty (THA) populations may reduce barriers and streamline the routine collection of PROs in clinical practice. As such, the purpose of this study was to determine if augmenting the Hip disability and Osteoarthritis Outcome Score-Joint Replacement (HOOS, JR) with additional HOOS questions would result in a PRO platform that could be used across a wider spectrum of hip patient populations. HYPOTHESIS:The HOOS, JR would demonstrate a notable ceiling effect, but by augmenting the HOOS, JR with additional HOOS questions, a responsive PRO platform could be created. STUDY DESIGN:Cohort study (diagnosis); Level of evidence, 2. METHODS:Using preoperative and postoperative HOOS responses from a sample of 304 patients undergoing periacetabular osteotomy (PAO), additional items were identified to augment the HOOS, JR. The psychometric properties of a newly created PRO tool (HOOSglobal) were then compared with the HOOS, JR and other PRO instruments developed for patients with hip OA and/or undergoing THA. RESULTS:By augmenting the HOOS, JR with 2 additional questions, the HOOSglobal was more responsive than all other included PRO tools and had significantly fewer maximum postoperative scores than the HOOS, JR ( P < .0001), HOOS-Physical Function Short form ( P < .0001), Western Ontario and McMaster Universities Osteoarthritis Index ( P = .02), University of California, Los Angeles activity scale ( P = .0002), and modified Harris Hip Score ( P = .04). The postoperative HOOSglobal score threshold associated with patients achieving the patient acceptable symptom state (PASS) was 62.5. CONCLUSION:The HOOSglobal is a valid and responsive PRO tool after PAO and may potentially provide the orthopaedic community with a PRO platform to be used across hip-related subspecialties. For patients undergoing PAO, a postoperative HOOSglobal score ≥62.5 was associated with patients achieving the PASS.
