Development and validation of the isiZulu quality of recovery score

Abstract

Background: Recovery from anaesthesia and surgery is an important marker of the quality of perioperative care. One extensively validated score in assessing this is the Quality of Recovery-15 items (QoR-15) score. This study aimed to translate the QoR-15 score into isiZulu and validate both the original and translated version on an isiZulu speaking population. Methodology: A randomised quantitative observational study was performed testing the original and the translated version of the QoR-15 score. In a crossover format, patients were asked to complete both questionnaires with 40 minutes allowed between each questionnaire. A 100 mm visual analogue score (VAS) was completed by each participant as a comparative tool for overall quality of recovery. Results: There was good correlation between the English and isiZulu score 0.91 (p < 0.001) and substantial agreement between the scores (mean weighted kappa: 0.69). There was a negative correlation between duration of surgery and total QoR-15 scores for both the English (-0.3; p < 0.001) and isiZulu (-0.29; p < 0.001) questionnaires, and a positive correlation between VAS scores and total QoR-15 scores for both the English (0.38; p < 0.001) and isiZulu (0.38; p < 0.001) questionnaires. Conclusion: This study demonstrates that the QoR-15 score is suitable to use in an isiZulu speaking patient population. The translated isiZulu version is comparable to the English QoR-15 score and should be used to assess the QoR to improve patient care.

Quality of Recovery Following Orthopedic Surgery in Patients at an Academic Hospital in South Africa

“…27 An isiZulu translation of the QoR-15 has been validated. 21 This was used to supplement the English QoR-15 in cases where the patient preferred the isiZulu translation. Only 1 patient preferred to make use of this.…”

“…15 This is important in a resource-constrained South African setting, where studies on QoR are limited. 21,22…”

Validity and reliability of the Korean version of the Quality of Recovery-15 questionnaire

“…This single-paged QoR-15 has been shown to be highly valid and reliable in patients who have undergone general surgery [ 4 ]. The QoR-15 has been validated and translated into many languages, including Danish, Portuguese, Chinese, Swedish, and IsiZulu [ 13 – 17 ]. All translated versions of QoR-15 had sufficient validity and reliability for evaluating the quality of recovery.…”

A prospective clinical audit to evaluate postoperative quality of recovery in adults at New Somerset Hospital, Cape Town, South Africa

“…Exclusion criteria were a known psychiatric disturbance precluding complete co-operation, cognitive impairment (known, or suspected and confirmed using a cognitive impairment test), [7] inability to understand English (self-professed), [6] unavailability for interview postoperatively (day cases, transferred to another hospital, intensive care unit admissions or life-threatening complications), age <18 years, surgical procedures conducted under sedation alone, or after-hours surgery. We also excluded patients with severe pre-existing medical conditions that would limit objective postoperative assessment (e.g.…”

“…[5] The QoR scores have been translated and adapted for different social environments. [5] Recently, Sikhakhane et al [6] developed and validated an isiZulu translation of the QoR-15, demonstrating good validity of the isiZulu QoR-15 using psychometric methods. They also demonstrated that the original English QoR-15 is a valid tool for assessment of postoperative quality of recovery in a South African (SA) population.…”
