Abstract Introduction Operative notes play a valuable role in ensuring that surgical patients receive consistent and adequate care. There are many inherent difficulties affecting their quality. We performed a QI project to improve surgical operative notes at our centre. Method A questionnaire assessing subjective quality of operative notes was sent to all foundation doctors delivering post-operative care. Compliance to each inclusion recommendation in the RCS guidelines was analysed. A standardised template for operative notes was incorporated into the hospital’s electronic records system, compliance was then reassessed. Results Questionnaire responses (16) were better for typed vs hand-written notes in all domains: ease of accessing notes, following intra-operative steps, following post-operative plans and frequency of asking for additional information regarding plans. After implementation of the template, mean compliance across 19 RCS parameters improved from 69% (55 operations) to 89% (46 operations). Number of parameters with 100% compliance improved from 2/19 to 8/19. Compliance increased in 14/19 parameters, there was no change in 2/19 (already 100%) and a reduction was seen in 3/19. Conclusions Results from our analysis and questionnaire showed that typed notes were favourable when compared to hand-written. The introduction of a standardised electronic template, without investment in new software, improved compliance to RCS guidelines.

AbstractTopology optimization is typically used for suitable design suggestions for objectives like mean compliance, mean temperature, or model analysis. Some modern modeling technics in topology optimization require a nodal based material interpolation. Therefore this article is referred to a continuous material interpolation in topology optimization. To cover a smooth and differentiable density field, we address trigonometric shape functions which are infinitely differentiable. Furthermore, we extend a so-known global criteria method with a sharpening function based on binary cross-entropy, so that sharper solutions results. The proposed material interpolation is applied to different applications such as heat transfer, elasto static, and potential flow. Furthermore, these different objectives are together optimized using a multi-objective criterion.

Mean Compliance

In this paper, topology optimization problems with two types of body force are considered: gravitational force and centrifugal force. For structural design under both external and gravitational forces, a total mean compliance formulation is used to produce the stiffest structure. For rotational structural design with high angular velocity, one additional design criteria, kinetic energy, is included in the formulation. Sensitivity analyses of the total mean compliance and kinetic energy are derived. Finally, design examples are presented and compared to show the effects of body forces on the optimized results.

<p>Government Regulation No. 46/2013 has not been optimal in providing legal compliance on taxation for Micro, Small, and Medium Enterprises (MSMEs), especially in Yogyakarta. This policy was evaluated and amended with Government Regulation No. 23/2018. The amendment in tax policy for MSME actors was this research background to examine: First, how does the final income tax policy impact MSME taxpayers' compliance in Yogyakarta? Second, what are the legal compliance constraints of MSME taxpayers? The method used in this research was a juridical empirical, supported with the statute and conceptual approach. The results showed that the amendment in the final income tax tariff policy from 1% to 0.5%, as well as provide legal certainty of the timeframe of taxation had a positive impact on increasing taxpayer compliance. There was an increase in the number of taxpayers to 41,000 in 2019, or an increase of 15.5% compared to the number of taxpayers in 2017. However, tariff reduction has not been the answer to taxpayer non-compliance, the Regional Office of the Directorate General of Taxes of the Special Region of Yogyakarta still found tax avoidance. Tax compliance constraints were also caused by taxpayers' distrust of the government, poor tax morale, and tax knowledge. The government needs to conduct a cooperative compliance approach in taxation policies based on trust and dialogue between taxpayers and the government to improve MSME taxpayer compliance.</p><p><strong>Keywords:</strong> Tax Compliance; Final Income Tax Regulation; Micro; Small; Medium Enterprises.</p>

Background Accurate measurement of medication adherence using classical observational studies typically depends on patient self-reporting and is often costly and slow. In contrast, digital observational studies that collect data directly from the patient may pose minimal burden to patients while facilitating accurate, timely, and cost-efficient collection of real-world data. In Germany, ~80% of patients with multiple sclerosis (MS) treated with interferon beta 1b (Betaferon) use an electronic autoinjector (BETACONNECT), which automatically records every injection. Patients may also choose to use a medical app (myBETAapp) to document injection data and their well-being (using a “wellness tracker” feature). Objective The goal of this pilot study was to establish a digital study process that allows the collection of medication usage data and to assess medication usage among patients with MS treated with interferon beta-1b who use myBETAapp. Methods The PROmyBETAapp digital observational study was a mixed prospective and retrospective, noninterventional, cohort study conducted among users of myBETAapp in Germany (as of December 2017: registered accounts N=1334; actively used accounts N=522). Between September and December 2017, users received two invitations on their app asking them to participate. Interested patients were provided detailed information and completed an electronic consent process. Data from consenting patients’ devices were collected retrospectively starting from the first day of usage if historical data were available in the database and collected prospectively following consent attainment. In total, 6 months of data on medication usage behavior were collected along with 3 months of wellness tracker data. Descriptive statistics were used to analyze persistence, compliance, and adherence to therapy. Results Of the 1334 registered accounts, 96 patients (7.2%) provided informed consent to participate in the study. Of these, one patient withdrew consent later. For another patient, injection data could not be recorded during the study period. Follow-up of the remaining 94 patients ended in May 2018. The mean age of participants was 46.6 years, and 50 (53%) were female. Over the 6-month study period, persistence with myBETAapp usage was 96% (90/94), mean compliance was 94% of injections completed, and adherence (persistence and ≥80% compliance) was 89% (84/94). There was no apparent difference between male and female participants and no trend across age groups. The wellness tracker was used by 21% of participants (20/94), with a mean of 3.1 entries per user. Conclusions This study provides important information on medication usage among patients with MS treated with interferon beta-1b and on consenting behavior of patients in digital studies. In future studies, this approach may allow patients’ feedback to be rapidly implemented in existing digital solutions.

Shunt Impedance

The aim of this work was to demonstrate that the three compartments of the lung T network and the chest wall impedance (Zcw) can be identified from input and transfer impedances of the respiratory system if the pleural pressure is recorded during the measurements. The method was tested in six healthy volunteers in the range of 8–32 Hz. The impedances resulting from the decomposition confirm the adequacy of the monoalveolar structure commonly used in healthy subjects. Indeed, the T shunt impedance is well modeled by a purely compliant element, the mean compliance [0.038 +/- 0.081 (SD) l/kPa], which coincides within 9.5 +/- 6.3% of the alveolar gas compressibility derived from thoracic gas volume (0.036 +/- 0.011 l/kPa). The results obtained provide experimental evidence that the alveolar gas compression is predominantly isothermal and that lung tissue impedance is negligible throughout the whole frequency range. The shape of Zcw is consistent with a low compliance-low inertance pathway in parallel with a high compliance-high inertance pathway. We conclude that the proposed method is able to reliably identify the T network featuring the lung and Zcw.
