"Appropriateness of colonoscopy according to EPAGE II in a low resource setting: a cross sectional study from Sri Lanka".

BACKGROUND: Due to finite resources, the clinical decision to subject a patient to colonoscopy needs to be based on the evidence, regardless of its availability, affordability and safety. This study assessed the appropriateness of colonoscopies conducted in selected study settings in Sri Lanka. In the absence of local guidelines, audit was based on European Panel on Appropriateness of Gastrointestinal Endoscopy II (EPAGE II) criteria. METHODS: This cross-sectional study assessed consecutive patients who underwent colonoscopy between June to August 2015 at four main hospitals in Sri Lanka. Interviewer administered questionnaire and secondary data were collected by trained health staff. Indications were assessed according to EPAGE II criteria. RESULTS: Out of 325 patients, male female proportions were 57.2 and 42.8%. Mean (SD) age was 54.9 (12.1) years. Colonoscopies were appropriate in 61.2% (95% CI 55.8-66.3), uncertain in 28.6% (95% CI 23.9-33.7) and inappropriate in 10.2% (95% CI 7.3-13.9). Colonoscopy to evaluate abdominal pain has highest percentage of inappropriateness of 10.0%. However, 9.5% of these colonoscopies revealed Colo-Rectal Cancer (CRC), reflecting differences in the profile of local CRC patients. Colonoscopies with appropriate or uncertain indications are three times more likely to have a relevant finding than inappropriate indications (42.5% vs. 18.2%; OR 3.32, 95% CI 1.33-8.3; P = 0.008). CONCLUSIONS: Majority of colonoscopies are appropriate. However, it cannot be neglected that every one in ten patients undergo inappropriate colonoscopy. Proportion of inappropriateness was highest for the indication of chronic abdominal pain, of which, 9.5% of patients were diagnosed with CRC. This may reflect the different profile of local CRC patients in terms of symptom manifestation and other characteristics. In conclusion, the authors recommend formulation of national guidelines for colonoscopy indications based on current best evidence and local patient profile. Use of such prepared local guidelines will improve the efficient use of finite resources.

Knowledge and self-reported practices regarding leptospirosis among adolescent school children in a highly endemic rural area in Sri Lanka.

INTRODUCTION: Leptospirosis is a zoonotic disease, which has become a major public health threat in Sri Lanka. A majority of patients are farmers in rural endemic areas. The purpose of the present study is to describe the level of knowledge and frequencies of risky practices related to leptospirosis among a sample of rural school adolescents in Galgamuwa, Kurunegala district, a highly endemic area in Sri Lanka. METHODS: A descriptive cross-sectional study was conducted among 460 adolescents studying in grades 9 and 10 of government schools. Study participants were selected using a multistage cluster sampling technique. A structured, pretested, self-administered questionnaire was used to collect data on sociodemographic characteristics, knowledge on leptospirosis, and frequency of associated risky practices related to leptospirosis. RESULTS: The response rate was 100%. Fifty-two percent of respondents had a 'good' level of knowledge of leptospirosis. In the assessment of practices, 62% were involved in rice paddy cultivation either 'frequently' or 'rarely'. Seventy percent of the fathers and 50% of the mothers of the students were involved in paddy cultivation. Thirteen percent reported that they swam, bathed, or washed in ponds of stagnant water. Of the students involved in paddy cultivation, only 18% said they usually used gloves and boots 'frequently'. Among the 9% of students who handled cattle or buffalo, 61% reported washing their hands and feet after handling the animals. Good level of knowledge was significantly associated with involvement in paddy cultivation among the adolescents (p=0.45), fathers (p<0.001), and mothers (p=0.012). The level of knowledge was not significantly associated with practicing preventive measures for leptospirosis. CONCLUSIONS: Although the respondent's overall level of knowledge regarding leptospirosis was satisfactory, the study identified several important gaps in specific areas. Those who were involved or had parents involved in paddy cultivation had better knowledge. However, this knowledge was not translated into practice of personal preventive measures. Use of protective attire in paddy farming needs to be facilitated by health authorities.

Comparing the use of direct observation, standardized patients and exit interviews in low- and middle-income countries: a systematic review of methods of assessing quality of primary care.

Clinical records in primary healthcare settings in low- and middle-income countries (LMIC) are often lacking or of too poor quality to accurately assess what happens during the patient consultation. We examined the most common methods for assessing healthcare workers' clinical behaviour: direct observation, standardized patients and patient/healthcare worker exit interview. The comparative feasibility, acceptability, reliability, validity and practicalities of using these methods in this setting are unclear. We systematically review and synthesize the evidence to compare and contrast the advantages and disadvantages of each method. We include studies in LMICs where methods have been directly compared and systematic and narrative reviews of each method. We searched several electronic databases and focused on real-life (not educational) primary healthcare encounters. The most recent update to the search for direct comparison studies was November 2019. We updated the search for systematic and narrative reviews on the standardized patient method in March 2020 and expanded it to all methods. Search strategies combined indexed terms and keywords. We searched reference lists of eligible articles and sourced additional references from relevant review articles. Titles and abstracts were independently screened by two reviewers and discrepancies resolved through discussion. Data were iteratively coded according to pre-defined categories and synthesized. We included 12 direct comparison studies and eight systematic and narrative reviews. We found that no method was clearly superior to the others-each has pros and cons and may assess different aspects of quality of care provision by healthcare workers. All methods require careful preparation, though the exact domain of quality assessed and ethics and selection and training of personnel are nuanced and the methods were subject to different biases. The differential strengths suggest that individual methods should be used strategically based on the research question or in combination for comprehensive global assessments of quality.

Sri Lankan clinical practice guidelines: A methodological quality assessment utilizing the AGREE II instrument.

RATIONALE, AIMS, AND OBJECTIVES: Clinical practice guidelines (CPG) play a major role in patient care in Sri Lanka. This study evaluates the methodological quality of the Sri Lankan CPGs developed in 2007. METHODS: A total of 94 CPGs developed by several professional colleges in Sri Lanka in the year 2007 were evaluated by 2 independent reviewers using AGREE II instrument for their methodological quality. Item score being ≤3 points was defined as "poor quality". Each domain score was calculated according to AGREE II. A guideline was labelled as "strongly recommended" if 4 or more domains scored above 60%, "recommended for use with certain modification" if only 3 domain scores were above 60% or if 4 or more domain scores were between 30% and 60%, and "not recommended" if 4 or more domains scored less than 30%. RESULTS: Most (22.3%) guidelines were developed by the College of Pathologists. Most of the guidelines (>55%) poorly reported on all the items, except for items 1, 2, and 22 of AGREE II. Median domain scores [range] and the proportion of the guidelines with domain score of <30% were as follows: domain on scope and purpose (33.3% [2.8%-83.3%]; 42.6%), stakeholder involvement (14.9% [0.0%-61.1%]; 81.9%), rigour of development (6.1% [0.0%-49%]; 98.9%), clarity and presentation (30.5% [8.3%-61.1%]; 46.8%), and applicability (8.3% [4.2%-14.6%]; 100%). All CPGs scored 50% for "editorial independence". Reviewers reported the overall quality was poor in 86 (91.5%). Based on the definitions used in the study, of 94 CPGs, 8 (8.5%) could be recommended to be used with modifications, while 86 (91.5%) could not be recommended for clinical practice. CONCLUSIONS: The methodological quality of the CPGs was poor irrespective of the source of development. Major efforts are essential to update the CPGs according to the principles of evidence based medicine.

Prediction of colorectal cancer risk among adults in a lower middle-income country.

BACKGROUND: Globally, colorectal cancer (CRC) is ranked as the third most common cancer in men and the second in women. Use of a simple, validated risk prediction tool will offer a low-cost mechanism to identify the high-risk individuals for CRC. This will increase efficient use of limited resources and early identification of patients. The aim of our study was to develop and validate a risk prediction model for developing CRC for Sri Lankan adults. METHODS: The risk predictors were based on the risk factors identified through a logistic regression model along with expert opinion. A case control design utilizing 65 CRC new cases and 65 hospital controls aged 30 years or more was used to assess the criterion validity and reliability of the model. The information was obtained using an interviewer administered questionnaire based on the risk prediction model. RESULTS: The developed model consisted of eight predictors with an area under the curve (AUC) of 0.849 (95% CI: 0.8 to 0.9, P<0.001). It has a sensitivity of 76.9%, specificity of 83.1%, positive predictive value (PPV) of 82.0%, negative predictive value (NPV) of 79.3%. Positive and negative likelihood ratios are 4.6 and 0.3. Test re-test reliability revealed a Kappa coefficient of 0.88. CONCLUSIONS: The model developed to predict the risk of CRC among adults aged 30 years and above was proven to be valid and reliable and it is an effective tool to be used as the first step to identify the high-risk population who should be referred for colonoscopy examination.
