Moroccan adaptation and validation of the rhinosinusitis quality-of-life survey

Cross-cultural adaptation and psychometric properties of patient-reported outcome measures in Arabic speaking countries: A scoping review

BACKGROUND

Patient-reported outcome measures (PROMs) are increasingly recognized as an indicator of healthcare quality and safety. Over the past decades, there has been a growing interest in using PROMs in Arabic-speaking populations. However, there is a paucity of data regarding the quality of their cross-cultural adaptation (CCA) and measurement properties.

OBJECTIVES

To identify PROMs that have been developed, validated or cross-culturally adapted to Arabic and evaluate methodological qualities of CCA and measurement properties.

METHODS

MEDLINE, EMBASE, CINAHL, PsycINFO, IPA, and ISI Web of Science were searched using search terms 'PROMs', 'Arabic countries', 'CCA', and 'psychometric properties'. Measurement properties were evaluated using COSMIN quality criteria and CCA quality was assessed using the Oliveria rating method.

RESULTS

This review included 260 studies with 317 PROMs, focusing on psychometric testing (83.8%), CCA (75.8%), utilizing PROMs as outcome measures (13.4%), and developing PROMs (2.3%). Out of the 201 cross-culturally adapted PROMs, forward translation was the most frequently reported component of CCA (n = 178), followed by back translation (n = 174). Out of the 235 PROMs that reported measurement properties, internal consistency was the most frequently reported measurement property (n = 214), followed by reliability (n = 160) and hypotheses testing (n = 143). Other measurement properties were less reported, including responsiveness (n = 36), criterion validity (n = 22), measurement error (n = 12), and cross-cultural validity (n = 10). The strongest measurement property was hypotheses testing (n = 143), followed by reliability (n = 132).

CONCLUSION

There are several caveats regarding the quality of CCA and measurement properties of PROMs included in this review. Only 1 out of 317 Arabic PROMs met CCA and psychometric optimal quality criteria. Therefore, there is a need to improve the methodological quality of CCA and measurement properties of PROMs. This review provides valuable information for researchers and clinicians when choosing PROMs for practice and research. There were only 5 treatment-specific PROMs, indicating the necessity for more research focusing on development and CCA of such measures.

Experience of People With Chronic Sinusitis During COVID-19 Lockdown in Saudi Arabia: Insights and Lessons

Background This study aims to evaluate the effect of the COVID-19 lockdown period on chronic rhinosinusitis (CRS) symptoms control. Methodology This cross-sectional study was carried out on adult patients (aged ≥18 years) who visited King Abdulaziz University Hospital within six months before the lockdown starting date. Background information, including patients' diagnosis, presence of rhinitis, number of previous surgeries, and medications, was collected. CRS symptom burden was measured using a validated Arabic version of the 22-item Sino-Nasal Outcome Test (SNOT-22). Study participants were required to complete the survey two months after the start of the lockdown. Results Out of 66 patients, 43 agreed to participate. The majority of respondents (34, 75.6%) were diagnosed with CRS with nasal polyps. The study revealed no differences between pre- and post-lockdown total symptom scores. Conclusions The COVID-19 pandemic has affected the health system worldwide in many ways. Regarding the scope of our study, CRS symptoms, fortunately, did not worsen with the pandemic. This is considered the first reported study to assess such symptom control among people with CRS in Saudi Arabia during the COVID-19 lockdown period.

Cross-cultural adaptation and validation of the 22-item sinonasal outcome test (SNOT-22) in German-speaking patients: a prospective, multicenter cohort study

Purpose

Chronic rhinosinusitis (CRS) is a common condition associated with a significant reduction of the health-related quality of life. One of the most widely used assessment tools in CRS is the disease-specific, health-related questionnaire SNOT-22. The aim of this study was to translate and validate the SNOT-22 into the German language.

Methods

The questionnaire was translated using the forward–backward translation technique. After the translation its reliability, validity, and sensitivity were evaluated. For this purpose, the questionnaire was completed by patients diagnosed with CRS before, 3 months and 1 year after endoscopic sinus surgery and by healthy individuals as controls at three university hospitals in Germany. The individual scores of the questionnaire before surgery was correlated with the Lund–Mackay score as well as a global disease-specific question.

Results

A total of 139 CRS patients and 31 healthy individuals participated in the study. Internal consistency at all timepoints was very good, with Cronbach’s alpha scores of 0.897, 0.941, and 0.945. The questionnaire was able to discriminate between CRS patients and control subjects (p < 0.0001) and scores improved significantly 3 month and 1 year after sinus surgery (p < 0.0001), indicating a good test–retest reliability, validity, and responsiveness. A significant correlation to the single global disease-specific question could be found (p < 0.0001), but no correlation with the Lund–Mackay score.

Conclusion

The German Version of the SNOT-22 is a reliable, valid, and sensitive instrument for measuring health-related quality of life in patients with CRS. It can be recommended for clinical practice and outcome research for German-speaking patients.

Woakes' syndrome

Woakes' syndrome is a rare entity defined as recurrent sinonasal polyposis with a consequent nasal pyramid deformity. Only a few cases are reported in the literature. The goal of this study is to present the features of Woakes' syndrome through a clinical case. A 42-year-old man presented with a history of ASA triad. He started self-medication for 5 years. He returned to the otorhinolaryngology department for the aggravation and persistence of symptoms. CT scans showed the deformity and thinning of the nasal bones. A functional endoscopic sinus surgery and correction of nasal pyramid deformity were performed. At 6 months' follow-up, good functional and aesthetic outcomes were observed. Woakes' syndrome was described more than 130 years ago. Treatment includes endoscopic sinonasal surgery and local treatment. Adequate management and good adherence to the therapeutic protocol could be factors to prevent this syndrome.

Comparison of Sino-Nasal Outcome Test 22 Symptom Scores in Rhinogenic and Odontogenic Sinusitis

BACKGROUND

Odontogenic maxillary sinusitis (OMS) and rhinogenic sinusitis (RS) are the main types of chronic rhinosinusitis (CRS) and have a significant impact on health-related quality of life (HRQL), but the difference in HRQL and symptom presentation between them has not been specifically evaluated to date. Obejctive: Our aim was to compare patterns of symptoms and HRQL disease-specific domains in patients affected with these 2 types of CRS.

METHODS

A group of 201 patients with CRS (99 with rhinogenic and 102 with odontogenic origin) completed the Sino-Nasal Outcome Test 22 (SNOT-22) questionnaire before treatment. Data sets were analyzed by using principal component analysis (PCA) to identify a set of symptom components together with the items excluded from PCA, which were then analyzed for differences between patients with OMS and RS.

RESULTS

PCA of SNOT-22 items identified 5 components: "rhinologic," "extranasal rhinologic," "ear/facial," "sleep and functional disturbance," and "emotional disturbance." Sneezing was excluded from PCA and treated as separate outcome variable and was significantly worse in RS patients. Patients with OMS scored significantly higher scores with regard to emotional disturbance, while RS patients scored significantly worse in sleep and functional disturbance. The extra symptom "malodor" was the most different symptom and was significantly worse in OMS patients. The total SNOT-22 score was not significantly different between the groups.

CONCLUSION

With controlling of covariates that may influence the severity of the disease, this study showed some significant differences in symptom patterns and HRQL impairment between patients with OMS and RS. Malodor is the most characteristic feature of OMS. Therefore, OMS should always be suspected in patients complaining of bad breath.
