Abstract

Objectives: Addressing the challenge of cost-effective asthma diagnosis amidst diverse symptom patterns among patients, this study aims to develop a machine learning-based asthma prediction tool for self-detection of asthma. Methods: Data from 6,665 participants in the Sri Lanka Health and Ageing Study (2018-2019) are used for this research. Thirteen machine learning algorithms, including Logistic Regression, Support Vector Machine, Decision Tree, Random Forest, Na¨ıve Bayes, K-Nearest Neighbors, Gradient Boost, XGBoost, AdaBoost, CatBoost, LightGBM, Multi-Layer Perceptron, and Probabilistic Neural Network, are employed. Results: A hybrid version of Logistic Regression and LightGBM outperformed other models, achieving an AUC of 0.9062 and 79.85% sensitivity. Key predictive features for asthma include wheezing, breathlessness with wheezing, shortness of breath attacks, coughing attacks, chest tightness, nasal allergies, physical activity, passive smoking, ethnicity, and residential sector. Conclusion: Combining Logistic Regression and LightGBM models can effectively predict adult asthma based on self-reported symptoms and demographic and behavioural characteristics. The proposed expert system assists clinicians and patients in diagnosing potential asthma cases.

Abstract

Objective
To compare the quality of clinical care and patient satisfaction in public and private outpatient primary care services in Sri Lanka.

Methods
A prospective, cross-sectional comparison was done by direct observation of patient encounters and exit interviews of outpatients in 10 public hospital general outpatient clinics and 66 private practitioner clinics in three districts of Sri Lanka. A total of 1027 public sector patients and 944 private sector patients were surveyed. Data were collected for 39 quality indicators covering diarrhoea, cough, hypertension, diabetes, asthma, upper respiratory tract infections (URTI) and five other conditions, along with prescribing indicators. The exit interviews collected data for 10 patient satisfaction indicators.

Results
The public sector performed better for some conditions (diarrhoea, cough and asthma) and the private sector performed better for others (hypertension, diabetes, URTI and tonsillitis). Overall quality was similar between the sectors in the domains of history taking, examination and investigations and management, but the private sector performed much better on patient education (57 vs 12%). Overall patient satisfaction was high in both sectors (98%), although the private sector performed much better in interpersonal satisfaction (94 vs 84%) and system-related indicators (95 vs 84%). Comparisons with studies from other countries suggest that both sectors perform considerably better than India, and similarly in many indicators to high-income countries.

Conclusions
Quality of outpatient primary care in Sri Lanka is generally high for a lower-middle income developing country. The public and private sectors perform similarly, except that private sector patients have longer consultations, are more likely to receive education and advice, and obtain better interpersonal satisfaction. The public system, with its limited funding, is able to deliver care in diagnosis and management that is similar to the private sector, while private sector patients, who spend more on their healthcare receive better quality care in non-clinical areas.

Quality of inpatient care in public and private hospitals in Sri Lanka

Quality of inpatient care in public and private hospitals in Sri Lanka sachini Thu, 06/27/2024 - 05:39

Abstract

Methods: A retrospective, cross-sectional comparison was done of inpatient quality, in a sample of 11 public and 10 private hospitals in three of 25 districts. Data were collected for 55 quality indicators from medical records of 2523 public and 1815 private inpatient admissions. These covered treatment of asthma, acute myocardial infarction (AMI), childbirth and five other conditions, along with outcome indicators, and medicine prescribing indicators.

Conclusions: For a range of indicators where comparisons were possible, quality of inpatient clinical care in Sri Lanka was comparable to levels reported from upper-middle income Asian countries, and often approaches that in developed countries, although the findings cannot be generalized. Quality in the public sector is better than in the private sector in many areas, despite spending being substantially less. Quality in public hospitals is resource constrained, and needs greater government investment for improvement, but when resource limitations are not critical, the public sector appears able to deliver equal or better quality than the private sector. Overall similarities in quality between the two sectors suggest the importance of physician training and other factors.
