Objective: We evaluated the comparability and repeatability of analyses based on uroflowmetry reports among urologists in Indonesia. Material & Methods: We assessed the inter-observer agreement when interpreting urodynamic examinations. Four urologists analyzed 20 sets of uroflowmetry data and gave their interpretations of the normality of the curve, reason of abnormality, grade classification, and pattern of the uroflowmetry curves. The consensus among observers was analyzed using the kappa statistic. Results: The kappa values for the analyses of the normality of the curves indicated fair to the moderate agreement. Agreement on the reason of abnormality showed poor to fair consensus. The shape of the flow curve had kappa values ranging from 0.047 to 0.225, indicating poor to fair consensus. Based on grade also showed kappa value from 0.047 to 0.169, indicating a poor agreement. Conclusion: Interpretations of uroflowmetry tracings showed only the poor to a fair agreement despite the normality of the uroflow curve. Variability in interpretation can strongly impact patient treatment. Therefore, further work is needed to standardize the reporting and interpretation of uroflowmetry studies to optimize patient care.

Activity Questionnaires

Background:Our study aims to compare the short and full-length International Physical Activity Questionnaires (IPAQ).Methods:Both versions were completed by 186 subjects >14 y living in southern Brazil. Half answered the short and then the long version; the remaining subjects followed the reverse order. Physical inactivity (PI) was defined as <150 min/wk spent in moderate or vigorous activities. The Bland and Altman method and the kappa statistic were used to assess agreement between the continuous and categorical outcomes, respectively.Results:The prevalence of PI was 50% higher with the short IPAQ (42% vs. 28%). The kappa value was 53.7%. Although the correlation coefficient was moderately high (r=0.61), agreement between methods was low.Conclusions:Both analyses used show that the short and full-length IPAQ versions have poor agreement. Utilization of inappropriate statistics would lead to misinterpretation. Researchers should exercise care before comparing studies using different IPAQ versions.

Kappa Value

SummaryThe kappa coefficient is a widely used measure of agreement between observers’ independent recording of diagnoses. Kappa adjusts the overall agreement for expected chance agreement. The dependence of kappa on the prevalence . of a diagnosis has not previously been emphasized. This dependence means that kappa does not give a general statement of the reproducibility of a diagnosis. The result of a study of observer agreement should, therefore, not – as it has been done in several studies – be given by the kappa value alone. The kappa value should always be given together with the original results of the study.

SummaryThis study examines inadequacy rates for phlebography in two multicenter trials for the prevention of post-operative DVT and determines inter- and intra-observer variability in evaluating phlebograms. A total of 991 (I) and 385 (II) patients underwent bilateral phlebography in two studies of thromboprophylaxis. Phlebography was performed using a standard method designed to visualize and assess all deep veins. Each vein was scored as normal, DVT or inadequate by both local and central assessment. The study showed low inadequacy rates for phlebograms of 12.2% (121/991) and 6.5% (25/385). Inter-observer agreement (local vs. central assessment) was moderate in both studies (1:74.8%, Kappa-value 0.41; II: 82.6%, Kappa-value 0.51). Good intraobserver agreement (within the central assessment group) was observed (I: 88.8%, Kappa-value 0.75). This study demonstrates low inadequacy rates for phlebograms using a standardized methodology and superior intra-observer agreement compared to inter-observer agreement and supports the importance of central assessment of phlebograms in thromboprophylactic multicenter trials to reduce observer variability.

The Ideal

Several classification systems have been proposed for endometriosis but the search for the ideal system is ongoing. While the most commonly used system has historically been r-ASRM, this system is not fit for purpose, particularly for deep endometriosis. In order to explore strategies to devise a new system and learn from problems with the existing ones, this study was designed to assess the reproducibility of each component in r-ASRM and its total score using videotaped laparoscopic procedures. Two surgeons independently scored 64 edited videos of laparoscopic endometriosis procedure, twice. Using the Kappa statistic, the agreement of the scores given was analyzed. r-ASRM showed a moderate inter-observer agreement (ƙ = 0.503) and good intra-observer agreement (ƙ = 0.774 and 0.682 for scorer 1 and 2 respectively) for overall disease staging. The agreement for each component of the system, however, was highly variable. The least agreement was observed for the peritoneum with ƙ = 0.157 and ƙ = 0.362 respectively for inter-observer and intra-observer. The lowest intra-observer agreement was seen for cul-de-sac for scorer 2 (ƙ = 0.382). Whilst the overall rASRM shows acceptable agreement between two scorers, this agreement seems to be the product of inconsistent scoring for each component.

Careful Thought

SummaryUK mental healh services have been distinguished by their continuity of care but recently there has been a move to separating consultant responsibility for in-patient and out-patient care. Local examples of the success of this approach have been published but there has been remarkably little careful thought about its longer-term impacts. International comparisons would suggest that there are significant potential disadvantages, including increased bed pressures. Some disadvantages, such as the poor fit with the Mental Health Act and patient dissatisfaction with structural discontinuity are already obvious. A more considered debate is called for.

Abstract The concentrated contact formed between a steel ball and a glass disc—the optical elastohydrodynamic lubrication (EHD) rig—has been the primary instrument for experimental investigations of elastohydrodynamic film thickness. It has been a source for values of pressure-viscosity coefficient, a difficult-to-define property of liquids. However, comparisons with the pressure dependence of the viscosity obtained in viscometers show little agreement. There are multiple reasons for this failure including shear-thinning and compressibility of the oil. Another reason for the poor agreement is the subject of this short note. The optical EHD rig using glass as one surface will only be in the piezoviscous-elastic (EHD) regime when the pressure-viscosity coefficient is large. For low values, it would be operating in the isoviscous-elastic regime (soft EHD).

Test Retest Reliability

AbstractObjectiveTo test the reliability and validity of the DIGS in Spanish population.MethodsInter-rater and test-retest reliability of the Spanish version of DIGS was tested in 95 inpatients and outpatients. The resultant diagnoses were compared with diagnoses obtained by the LEAD (Longitudinal Expert All Data) procedure as “gold standard”. The kappa statistic was used to measure concordance between blind inter-raters and between the diagnoses obtained by LEAD procedure and through the DIGS.ResultsOverall kappa coefficient for inter-rater reliability was 0.956. The kappa value for individual diagnosis varied from major depression = 0.877 to schizophrenia = 1. Test-retest reliability was 0.926. Kappa for all individual target diagnoses ranged from 0.776 (major depression) to 1. Kappa between LEAD procedure and DIGS ranged from 0.704 (major depression) to 0.825 (bipolar I disorder).ConclusionMost of the DSM-IV major psychiatric disorders can be assessed with acceptable to excellent reliability with the Spanish version of the DIGS interview. The Spanish version of DIGS showed an acceptable to excellent concurrent validity. Giving the good reliability and validity of Spanish version of DIGS it should be considered to identify psychiatric phenotypes for genetics studies.

Secondary Alveolar Bone Grafting

Objective To assess if a 4-point, radiographically based scale could be used between operators to reliably assess the success of secondary alveolar bone grafting. Design The study was retrospective with the clinicians blind to patient identity. Radiographs were examined twice by two clinicians with 1 week between assessments. Setting The research was carried out in a hospital-based orthodontic/oral and maxillofacial unit. Patients All patients who had secondary alveolar bone grafting in this unit between February 1992 and March 1995 were included In this study. There were 38 patients with a total of 48 grafted sites. Interventions The bone graft site was radiographed following orthodontic expansion prior to grafting. The radiograph was repeated postoperatively at a mean of 4 months after surgery. Main Outcome Measure The degree of bony fill in the cleft area was assessed using a 4-point scale: Grade 1 >75% bony fill; Grade 2 50–75% bony fill; Grade 3 < 50% bony fill; Grade 4 no complete bony bridge. Results Overall, 50% of grafts achieved grade 1, 23% were grade 2, 22% grade 3, and 5% grade 4. Levels of intra- and inter-observer agreement were highly variable (.33 to .72 kappa statistic). Conclusions The 4-point scale described could be used to assess the success of autogenous secondary alveolar bone grafting. It showed moderate to substantial intra-observer agreement, and fair-to-moderate inter-observer agreement.

AbstractIntroduction:The purpose of the study was to document the occurrence and causes of disagreements between paramedics in a tiered-response emergency medical services (EMS) system.Methods:This cohort analysis of disagreements between paramedics sampled 63 male public agency, 90 male private agency, and 41 female private agency paramedics. Paramedics responded to Likert-type items and one open-ended item concerning the occurrence of conflict between paramedics.Results:On-scene conflict between EMS personnel from public and private agencies was reported by 70% of the respondents. Conflicts that interfered with patient care were reported to occur more frequently between paramedics from different types of agencies. The most commonly mentioned subject of disagreement was patient treatment, followed by patient transport, interpersonal and interagency conflicts, and patient assessment.Conclusion:A majority of paramedics have experienced on-scene disagreements with other paramedics. Disagreements occur more frequently between paramedics from different agencies and encompass a wide range of issues concerning patient care and interpersonal relationships.

The Impact

A Review of: Farrell, A., Mason, J. (2014). Evaluating the Impact of Literature Searching Services on Patient Care Through the Use of a Quick-Assessment Tool. Journal of the Canadian Health Libraries Association, 35(3),116-123. doi: 10.5596/c14-030 Abstract Objective – To assess the impact of a library provided literature search service on patient care. Design – Multiple choice questionnaire survey. Setting – Hospital library. Subjects – 54 library users who had requested a literature search and indicated the primary purpose of their request was patient care. Methods – A multiple choice questionnaire survey was designed, building on previously published library impact surveys and best practice guidelines, with input from staff in the local research department. The survey was reviewed by library staff, researchers and prospective respondents and piloted. The survey was sent out with the answers to literature search requests and a small incentive was offered to those who completed the survey. The survey was followed up with reminders. Main results – The response rate was 57.5% (n=54/94). The most common staff groups requesting literature searches were physicians (33.3%), nurses (22.2%), therapists (16.7%), pharmacists (11.1%) and residents (7.4%). The majority stated that their questions had been answered (77.8%), while 18.5% indicated their questions had been partially answered, for reasons such as the answer leading to more questions, or parts of the question had not been addressed. Two (3.7%) of the respondents’ questions were not answered, either because no answer existed, or because the question didn’t contain enough detail. Of those who replied that their question had been answered, 64.3% judged the information to have had an immediate impact on patient treatment or management. Other uses of the information included refreshing memory, avoiding an adverse event, diagnosing a patient, or preventing a referral. The percentage of respondents judging there to be no immediate impact on patient care was 16.7%. The impact on diagnosis and treatment was further investigated in those who had said there had been an immediate impact, with 22.2% saying the information determined their choice of drug, 29.6% saying the information confirmed their choice of drug, while 18.5% stated the information changed their choice of drug. All respondents replied that they intended to use this information in the future, regardless of whether the information had an immediate impact, or if their question had been answered. Conclusion – The authors concluded that the survey results show hospital libraries can have an impact on patient care through a literature searching service. They also found that the library was answering its literature service users’ questions.
