PurposeThis conceptual paper presents a proposal for improving a performance measurement (PM) system implementation process based on enterprise engineering (EE) guidelines, which gives the process a sense of completeness.Design/methodology/approachThis paper analyzes a well-known process for PM systems implementation organized in two phases: identifying, designing and implementing the top-level performance measures; and cascading the top-level measures and identify appropriate lower-level performance measures. The proposed improvements to the studied process derive from the EE guidelines, which establish a basis for the structure of an organizational management system, the formalization and synchronization of processes, performance expectations, exception handling and change management.FindingsThe study reveals that not all EE guidelines are covered by the analyzed process, with four of them having no evidence of being adopted: involvement of people in process design and implementation; ensuring interoperability between different systems in the information structure; addressing of all possible exceptions; coherence and consistency of semantics across all processes.Originality/valueBy the lens of EE guidelines, this paper advances a how-to-guide. This paper can support managers and researchers on PM system design and implementation, given the importance and relevance of EE recommendations having a consistent and well-structured procedure.

Abstract Background Eligibility guidelines in research trials are necessary to minimise confounds and reduce bias in the interpretation of potential treatment effects. There is limited extant research investigating how being deemed ineligible for such trials might impact patients’ perceptions of themselves and of research. Better understanding of the impact of patient ineligibility could enhance design and implementation of future research studies. Methods Eight semi-structured telephone interviews were conducted to explore the impact of ineligibility on self-perceptions; perceptions regarding the nature of research; and the likelihood of expressing interest in future research. Data were collected and analysed thematically through inductive, interpretive phenomenological analysis (IPA). Results Five themes emerged regarding the experience of being deemed ineligible: (1) Being deemed ineligible is emotion and reaction evoking; (2) ‘Doing your bit’: Helping others and increasing the value of research; (3) Communication of ineligibility; (4) Appreciation for those who express interest; and (5) Subsequent perceptions and attitudes towards research. Conclusions The results suggest that being deemed ineligible can elicit negative emotional outcomes but is not likely to change perceptions of or attitudes towards research, possibly due to a desire to help similar others. Ineligibility can impact future participation in some cases, thus reducing the recruitment pool for subsequent research studies. Recommendations are provided to help minimise this risk. Advising of ineligibility in a personal way is recommended: with enhanced clarity regarding the reasoning behind the decision; providing opportunities to ask questions; and ensuring that appreciation for the patient’s time and interest are communicated.

Phase-locked loop (PLL) operates at a high frequency and due to the increased switching rate of the circuits, the power consumption is high. Designing a PLL which consumes less power without compromising the frequency of operation is essential. The sub-components of PLL such as the phase frequency detector, charge pump, loop filter, voltage-controlled oscillator, and the frequency divider have to be designed for reduced power consumption. The proposed PLL along with its sub-components have been designed using the CMOS 180nm technology library in the Cadence Virtuoso and simulated using Cadence Spectre with a supply voltage of 1.8V resulting in a 20% reduction in power with a higher frequency of operation compared to the reference PLL architecture. The capture range and lock range of the proposed PLL are 2.09 to 2.14 GHz and 1 to 3.5GHz, respectively. The designed PLL consumes less power and operates at a higher frequency.

Abstract Background Registries are powerful clinical investigational tools. Although in hospitals registries may be mandated, industry-sponsored, international registries are voluntary and therefore can require clearer objectives and more planning. The registry also needs sufficient resources and appropriate measurement tools to motivate long-term participation and ensure success. Methods We summarize our learnings from 10 years of running a medical device registry that surveys patient-reported benefits of hearing implants. Results We enlisted 77 participating clinics globally, who actively recruited a total of more than 1500 hearing implant users. We identified the stages in developing a registry specific to hearing loss. Furthermore, we report the challenges and successes in design and implementation and make recommendations for future registries. Conclusions Data collection infrastructure needs to be kept up to date throughout the defined registry lifetime, and it is essential to oversee data quality and completeness. Compliance at registry sites is important for data quality and needs to be weighed against the cost of site monitoring. To motivate sites to enter data accurately and expeditiously, we facilitated easy access to their own data which helped to support their clinical routine. Trial registration ClinicalTrials.gov NCT02004353. 9th December 2013.
