Measuring tuberculosis patient perceived quality of care in public and public–private mix settings in India: an instrument development and validation study

[摘要] Background At present, there are no validated quantitative scales available to measure patient-centred quality of care in health facilities providing services for tuberculosis (TB) patients in India and low-income and middle-income countries.Methods Initial themes and items reflective of TB patient’s perceived quality of care were developed using qualitative interviews. Content adequacy of the items were ascertained through Content validity Index (CVI) and content validity ratio (CVR). Pilot testing of the questionnaire for assessing validity and reliability was undertaken among 714 patients with TB. Sampling adequacy and sphericity were tested by Kaiser-Meyer-Olkin and Bartlett’s test, respectively. Exploratory and confirmatory factor analysis was undertaken to test validity. Cronbach’s α and test–retest scores were used to test reliability.Results A 32-item tool measuring patient-perceived quality of TB distributed across five domains was developed initially based on a CVI and CVR cut-off score of 0.78 and cognitive interviews with patients with TB. Bartlett’s test results showed a strong significance f (χ2=3756 and p1.96) between items and factors was highly significant and Cronbach’s α was acceptable for the global scale (0.76) for the four factors. Intraclass correlation coefficient and the test retest scores for four factors were (<0.001) significant.Conclusion We validated a measurement tool for patient-perceived quality of care for TB (PPQCTB) which measured the patient’s satisfaction with healthcare provider and services. PPQCTB tool could enrich quality of care evaluation frameworks for TB health services in India.
