OBJECTIVES: To generate consensus among dermatologists on the content of an outpatient discharge checklist, to create one and to seek clinicians' opinions on its usefulness.
METHODS: Seventeen consultant dermatologists from five National Health Service trusts completed a 72-item Delphi questionnaire. A five-point Likert scale was used to rate each item for importance in contributing to a high-quality discharge decision. Eighteen clinicians completed a questionnaire evaluating checklist use.
RESULTS: Consensus was determined when ≥ 75% of consultants rated an item 'very important' or 'important'. There was strong inter-rater reliability (intraclass correlation coefficient = 0·958) and fair inter-rater agreement (Fleiss kappa = 0·269). There were 26 consensus-agreed items, condensed to 13 that formed the 'traffic-light' checklist. These are disease-related issues (diagnostic certainty, disease severity, treatment appropriateness, patient manageable in primary care, patient's benefit from follow-up), patient empowerment issues (understanding diagnosis and treatment outcome, having a clear plan, treatment side-effects, ability to self-manage) and addressing concerns (patient concerns, easy reaccess to secondary care, whether patient and clinician are happy with the decision). Twelve clinicians (67%) found the checklist useful, 11 (61%) wanted to use it in future, 10 (56%) thought it was useful for training and three (17%) said it helped their thinking. Clinicians suggested its use for auditing and for training clinicians and administrators.
CONCLUSIONS: Items were identified to create an outpatient discharge information checklist, which demonstrated high acceptability.
OBJECTIVE: The purpose of this study was to report the worldwide experience with successful retrieval of the Micra TPS.
METHODS: A list of all successful retrievals of the currently available leadless pacemakers (LPs) was obtained from the manufacturer of Micra TPS. Pertinent details of retrieval, such as indication, days postimplantation, equipment used, complications, and postretrieval management, were obtained from the database collected by the manufacturer. Other procedural details were obtained directly from the operators at each participating site.
RESULTS: Data from the manufacturer consisted of 40 successful retrievals of the Micra TPS. Operators for 29 retrievals (73%) provided the consent and procedural details. Of the 29 retrievals, 11 patients underwent retrieval during the initial procedure (immediate retrieval); the other 18 patients underwent retrieval during a separate procedure (delayed retrieval). Median duration before delayed retrieval was 46 days (range 1-95 days). The most common reason for immediate retrieval was elevated pacing threshold after tether removal. The most common reasons for delayed retrieval included elevated pacing threshold at follow-up, endovascular infection, and need for transvenous device. Mean procedure duration was 63.11 ± 56 minutes. All retrievals involved snaring via a Micra TPS delivery catheter or steerable sheath. No serious complications occurred during the reported retrievals.
CONCLUSION: Early retrieval of the Micra TPS is feasible and safe.
METHODOLOGY: STROBE guidelines were used to design a study using 60 periodontal ligament samples obtained from healthy lower premolars where extraction was indicated for orthodontic reasons. Prior to extraction 40 of these premolars were equally divided into four groups and root canals were prepared using different systems: Mtwo, Reciproc Blue, HyFlex EDM and Plex-V. Ten premolars were prepared with hand files and served as a positive control group. The remaining 10 premolars where extracted without treatment and served as a negative control group. All periodontal ligament samples were processed to measure the expression of SP, CGRP and their receptors by radioimmunoassay. Kruskal-Wallis and Duncan tests were performed to determine statistically significant differences between the groups for each variable.
RESULTS: Greater expression of all the peptides measured were found in the hand-file preparation group, followed by the Reciproc Blue, Mtwo, HyFlex EDM and Plex-V groups. The lower SP, CGRP and their receptors values were for the intact teeth control group. Kruskal-Wallis test showed statistically significant differences amongst groups (p
