Purpose This study aimed to develop and validate an instrument to measure patient perception of quality of nursing care and related hospital services in a tertiary care setting. Methods We compiled an instrument with 72 items that patients may perceive as quality of nursing care and related hospital services, following an extensive literature search, discussions with patients and care providers and a brainstorming session with an expert panel. A cross-sectional study was conducted at the National Hospital of Sri Lanka. A sample (n = 120) of patients stayed in general surgical or medical units responded to the interviewer administered instrument upon discharge. Item analysis and principal component factor analysis were performed to assess validity, and internal consistency was calculated to measure reliability. Results Of the 72 items, 18 had greater than 20% of responses as ‘not relevant’. A further 11 items were eliminated since item-total correlations were less than .2. Factor analysis was performed on remaining 43 items which resulted in 36 items classifying into eight factors accounting for 71% of the variation. Factor loadings in the final solution after Varimax rotation were interpersonal aspects (.68–.85), efficiency (.62–.79), competency (.66–.68),comfort (.60–.84), physical environment (.65–.82), cleanliness (.81–.85), personalized information (.76–.83),and general instructions (.61–.78). The instrument had high Internal consistency (Cronbach’s alpha = .91). Conclusion We developed a comprehensive, reliable and valid, 36-item instrument that may be used to measure patient perception of quality of nursing care in tertiary care settings.

Purpose: To validate the Cardiff Wound Impact Schedule (CWIS) to assess the health-related quality of life (HRQoL) of Sri Lankan patients with diabetic leg and foot ulcers. Methods: English version of CWIS was examined for cultural compatibility, translated into Sinhala and pretested. The Sinhala versionwas administered in parallel with the validated Sinhala version of SF-36 by an interviewer to all patients (n ¼ 140) at baseline to determine the construct validity. Reliability of CWIS was measured by internal consistency and test-retest stability. The instrument was readministered in 2 weeks on 33 patients with nonhealing ulcers to determine the test-retest stability and in 3 months on 50 patients with healed ulcers to determine the ability of CWIS to discriminate HRQoL between patients with healed versus nonhealed ulcers. Acceptability of CWIS was assessed by the response rate, completion rate and the average time taken to complete a single interview. Results: The construct validity demonstrated moderately significant correlations between related subscales of CWIS and SF-36 (Spearman’s r = .32 .51, p = .021 to p < .001) for the whole study sample. Internal consistencies (Cronbach a = .68 .86) and test-retest stability (.56 .70) were acceptable. The tool was sensitive in discriminating the impact of the wound on HRQoL in healed versus nonhealed status (p ≤ .001). The tool showed good acceptability. Conclusions: The Sinhala version of CWIS is valid, reliable and acceptable for assessing the impact of wound on HRQoL. This instrument is sensitive in detecting the differences of the impact of healed and nonhealed ulcers on QoL in patients with diabetic leg and foot ulcer.
