“…Consistency in repeated measurements based on the same protocol is often referred to as stability, whilst consistency in measurements made by different observers using the same protocol is referred to as equivalence (Heale and Twycross 2015). In public health, inter-observer agreement studies are commonly used to assess whether observations or measurements can reliably be made by community-based healthcare professionals (Laar et al 2018;Triasih et al 2015) rather than specialists. However, studies of inter-observer agreement are less common in low and middle income countries (Bolarinwa 2015) and environmental management.…”

Sanitary risk inspection, an observation protocol for identifying contamination hazards around water sources, is promoted for managing rural water supply safety. However, it is unclear how far different observers consistently identify contamination hazards and consistently classify water source types using standard typologies. This study aimed to quantify inter-observer agreement in hazard identification and classification of rural water sources. Six observers separately visited 146 domestic water sources in Siaya County, Kenya, in wet and dry seasons. Each observer independently classified the source type and conducted a sanitary risk inspection using a standard protocol. Water source types assigned by an experienced observer were cross-tabulated against those of his colleagues, as were contamination hazards identified, and inter-observer agreement measures calculated. Agreement between hazards observed by the most experienced observer versus his colleagues was significant but low (intra-class correlation = 0.49), with inexperienced observers detecting fewer hazards. Inter-observer agreement in classifying water sources was strong (Cohen's kappa = 0.84). However, some source types were frequently misclassified, such as sources adapted to cope with water insecurity (e.g. tanks drawing on both piped and rainwater). Observers with limited training and experience thus struggle to consistently identify hazards using existing protocols, suggesting observation protocols require revision and their implementation should be supported by comprehensive training. Findings also indicate that field survey teams struggle to differentiate some water source types based on a standard water source classification, particularly sources adapted to cope with water insecurity. These findings demonstrate uncertainties underpinning international monitoring and analyses of safe water access via household surveys.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

Standardized radiographic interpretation of thoracic tuberculosis in children

There is a lack of standardized approach and terminology to classify the diverse spectrum of manifestations in tuberculosis. It is important to recognize the different clinical and radiographic patterns to guide treatment. As a result of changing epidemiology, there is considerable overlap in the radiologic presentations of primary tuberculosis and post-primary tuberculosis. In this article we promote a standardized approach in clinical and radiographic classification for children suspected of having or diagnosed with childhood tuberculosis. We propose standardized terms to diminish confusion and miscommunication, which can affect management. In addition, we present pitfalls and limitations of imaging.

“…22 However, its inadequacy was evident, with frequent discrepancies between the different readers' interpretations, inconsistent quality and coexistence of multiple comorbidities such as viral respiratory infections and possible reactive airways disease. 2,9,21 The discordance between a CXR classified first by the attending clinician as 'suggestive of TB' and reclassified after consensus as either 'normal' or 'abnormal, but not suggestive of TB' was most likely because the clinician's assessment was clouded by awareness of the high risk of TB among young contacts with symptoms. Another limitation of CXRs being used as the reference standard is the classification of cases with extra-pulmonary TB and a normal CXR as non-TB cases, which led to an underestimation of specificity.…”

“…Of particular concern is the inability to confidently exclude TB disease without use of chest X-rays (CXRs) which are generally not available in most resource-limited settings, to allow safe use of IPT. 9,10 Symptom-based screening has been shown to be safe and effective in selecting the small proportion of child TB contacts requiring further evaluation for TB disease, and allowing prompt initiation of IPT for the remainder. [11][12][13][14] However, this approach has been evaluated in very few prospective studies, and many countries remain reluctant to implement it.…”

An evaluation of chest X-ray in the context of community-based screening of child tuberculosis contacts

Abstract: The CXRs of child TB contacts investigated in the community were characterised by low quality, low agreement and low yield. Our findings support guidelines that CXR is not routinely indicated in asymptomatic child TB contacts in this setting.
