Inter-rater agreement of scores to assess quality of care in public sector primary health care facilities – A pattern of performance

PurposeTo determine if the scores obtained from the Ideal Clinic Assessment Tool (ICAT) used to assess the quality of care in public Primary Health Care facilities in South Africa showed inter-rater agreement between self-assessments, district peer reviews and cross-district peer reviews. The ICAT scores obtained in the three types of reviews were paired as follows: self-assessments/district peer reviews, self-assessment/cross-district peer reviews and district/cross-district peer reviews. The global scores and averages of the Vital elements for the three paired reviews for 587 facilities across the country were compared using Bland-Altman plots.ResultsThe Bland-Altman plots showed no inter-rater agreement between the global scores and averages of the Vital elements for the facilities in any of the paired reviews (n = 1 761 reviews). Similarly, there was no inter-rater agreement between the global scores of the three paired reviews in any of the nine provinces in the country.ConclusionThere is still a need to continue to conduct both district and cross-district reviews despite the substantial cost of doing so. Further studies are required to determine what factors contributed to the disagreement in scores between the different types of reviews despite the preparatory training of reviewers.     

Continuous Utility Functions Through Scales

We present here a direct elementary construction of continuous utility functions on perfectly separable totally preordered sets that does not make use of the well-known Debreu’s open gap lemma. This new construction leans on the concept of a separating countable decreasing scale. Starting from a perfectly separable totally ordered structure, we give an explicit construction of a separating countable decreasing scale, from which we show how to get a continuous utility map.      

Modeling Two-state Disease Processes with Random Effects

Many chronic medical conditions are manifested by alternating sojourns in symptom-free and symptomatic states. In many cases, in addition to their relapsing and remitting nature, these conditions lead to worsening disease patterns over time and may exhibit seasonal trends. We develop a mixed-effect two-state model for such disease processes in which covariate effects are modeled multiplicatively on transition intensities. The transition intensities, in turn, are functions of three time scales: the semi-Markov scale involving the backward recurrence time for the cyclical component, the Markov scale for the time trend component, and a seasonal time scale. Multiplicative bivariate log-normal random effects are introduced to accommodate heterogeneity in disease activity between subjects and to admit a possible negative correlation between the transition intensities. Maximum likelihood estimation is carried out using Gauss-Hermite integration and a standard Newton-Raphson procedure. Tests of homogeneity are presented based on score statistics. An application of the methodology to data from a multi-center clinical trial of chronic bronchitis is provided for illustrative purposes.     

The Crucial Role of Nomothetic and Idiographic Conceptions of Time: Interdisciplinary Collaboration in Nuclear Waste Management

The disposal of nuclear waste involves extensive time scales. Technical experts consider up to 1 million years for the disposal of spent fuel and high‐level waste in their safety assessment. Yet nuclear waste is not only a technical but also a so‐called sociotechnical problem and, therefore, requires interdisciplinary collaboration between technical, natural, social sciences, and the humanities in its management. Given that these disciplines differ in their language, epistemics, and interests, such collaboration might be problematic. Based on evidence from cognitive psychology, we suggest that, in particular, a concept like time is presumably critical and can be understood differently. This study explores how different scientific disciplines understand extensive time scales in general and then focuses on nuclear waste. Eighteen qualitative exploratory interviews were conducted with experts for time‐related phenomena of different disciplines, among them experts working in nuclear waste management. Analyses revealed two distinct conceptions of time corresponding to idiographic and nomothetic research approaches: scientists from the humanities and social sciences tend to have a more open, undetermined conception of time, whereas natural scientists tend to focus on a more determined conception that includes some undetermined aspects. Our analyses lead to reflections on potential difficulties for interdisciplinary teams in nuclear waste management. We focus on the understanding of the safety assessment, on potential implications for communication between experts from different disciplines (e.g., between experts from the humanities and engineering for risk assessment and risk communication), and we reflect on the roles of different disciplines in nuclear waste management.     

我国商业银行规模经济及其状态比较

商业银行经营规模是决定或影响银行业运行效率的重要因素之一。利用中国商业银行1994—1999年的经营情况进行实证分析后可以发现,中国商业银行的运营存在着规模经济的现象。其中,新兴股份制商业银行的规模经济的程度明显高于国有商业银行。我们分析了公司治理结构、银行内部管理、金融创新及市场结构等影响我国商业银行规模经济的因素,给出了我国商业银行在进一步改革中的政策建议。

Measurement Issues in Human Behaviour Theory

Abstract

This paper provides a brief introduction to the use of standardized measurement scales in behavioural theory, discusses some of the limitations of the domain sampling model of measurement for behavioural scientists and practitioners, and identifies central measurement issues in behavioural theory that are germane to all measurement tools. The ever popular and useful behavioural checklist is used to introduce the domain sampling model of measurement and to describe how it can be treated as a standardized measurement tool.     

Stability and Validity of the Holden Psychological Screening Inventory (HPSI) in Psychiatric Inpatients

Abstract

Forty-seven psychiatric inpatients in a Canadian psychiatric hospital participated in an evaluation of the stability and validity of the Holden Psychological Screening Inventory (HPSI). Stability coefficients over a 1-month period were .85, .79, and .66 for the HPSI Psychiatric, Social, and Depression Symptomatology scales, respectively, and coefficient alpha reliabilities for these scales ranged between .76 and .89 across both time periods. Staff rating composite scales corresponding to the self-report HPSI scales had stability coefficients of .74, .85, and .82, respectively. As well, they had inter-rater reliabilities that ranged between .65 and .84 across both time periods. The 3 staff rating composites at time 1 correlated equivalently with the corresponding 3 primary HPSI scales at times 1 and 2 (p > .05). Similarly, the 3 staff rating composites at time 2 correlated equivalently with the corresponding 3 primary HPSI scales at times 1 and 2 (p > .05). Over a 1-month period, HPSI scale scores were very stable and correlations with criterion ratings were stable. Using a confirmatory factor analysis, with each of the 3 dimensions defined by the time 1 and 2 measures for the 3 HPSI scales and 3 staff rating composites, evidence for discriminant as well as convergent validity was obtained. In summary, the self-report HPSI and the staff rating composite measures evidenced sufficient reliability and validity to meet the requirements for routine clinical assessment work with psychiatric inpatients. Additionally, the stability data provide effects of retesting baseline data for assessing treatment outcome in this population.
