Evaluation of validity of the STOP-BANG questionnaire in major elective noncardiac surgery

Background

The STOP-BANG questionnaire screens for obstructive sleep apnoea (OSA) in surgical patients. In prior research, the association of STOP-BANG scores with comorbidities and outcomes was inconsistent. The objective of this study was to evaluate the validity of the STOP-BANG score.

Mixed-mode versus paper surveys for patient-reported outcomes after critical illness: A randomised controlled trial

ObjectiveThe aim of the study was to determine the response rate to a mixed-mode survey using email compared with that to a paper survey in survivors of critical illness.DesignThis is a prospective randomised controlled trial.SettingThe study was conducted at a single-centre quaternary intensive care unit (ICU) in Adelaide, Australia.ParticipantsStudy participants were patients admitted to the ICU for ≥48 h and discharged from the hospital.InterventionsThe participants were randomised to receive a survey by paper (via mail) or via online (via email, or if a non-email user, via a letter with a website address). Patients who did not respond to the initial survey received a reminder paper survey after 14 days. The survey included quality of life (EuroQol-5D-5L), anxiety and depression (Hospital Anxiety and Depression Scale), and post-traumatic symptom (Impact of Event Scale-Revised) assessment.Main outcome measuresSurvey response rate, extent of survey completion, clinical outcomes at different time points after discharge, and survey cost analysis were the main outcome measures. Outcomes were stratified based on follow-up time after ICU discharge (3, 6, and 12 months).ResultsA total of 239 patients were randomised. The response rate was similar between the groups (mixed-mode: 78% [92/118 patients] vs. paper: 80% [97/121 patients], p = 0.751) and did not differ between time points of follow-up. Incomplete surveys were more prevalent in the paper group (10% vs 18%). The median EuroQol-5D-5L index value was 0.83 [0.71–0.92]. Depressive symptoms were reported by 25% of patients (46/187), anxiety symptoms were reported by 27% (50/187), and probable post-traumatic stress disorder was reported by 14% (25/184). Patient outcomes did not differ between the groups or time points of follow-up. The cost per reply was AU$ 16.60 (mixed-mode) vs AU$ 19.78 (paper).ConclusionThe response rate of a mixed-mode survey is similar to that of a paper survey and may provide modest cost savings.     

Preoperative Sleep Questionnaires Identify Medical Emergency Team Activation in Older Adults

Patients with obstructive sleep apnea (OSA) have increased postoperative complications that are important for patient safety and healthcare utilization. Questionnaires help identify patients at risk for OSA; however, among older adults who preoperatively self-administered OSA questionnaires, the frequency of postoperative Medical Emergency Team Activation (META), rapid response, code blue, code stroke, is unknown.ObjectivesIdentify whether having OSA questionnaires completed by patients is feasible in the preoperative clinic. Determine the frequency of META among older patients at risk for OSA.Design and interventionCohort of prospective patients independently completed 2 OSA questionnaires in a preoperative clinic, STOP-Bang (SB) and ISNORED (IS). Observers blinded to questionnaire responses recorded incidence of META.setting and participantsOf the 898 consecutive patients approached in the preoperative assessment clinic and surgical navigation center, 575 (64%) consented and completed the questionnaires in <5 minutes and were included in the analysis.MeasuresSleep questionnaire responses and frequency of inpatient postoperative META.ResultsWith an affirmative response to ≥3 questions on either questionnaire, 65% of patients enrolled were at risk for OSA. Of these, 3.1% sustained an META. In patients at risk for OSA, META occurred in 7.6% (SB+) and 7.2% (IS+) vs 2.5% (SB+) and 1.7% (IS+) for low risk. METAs were disproportionately higher among patients aged ≥65 years (6.3% vs 1.7%; P < .018), American Society of Anesthesiologists (ASA) physical status class ≥3, and IS+. All patients with META positively answered ≥3 of 15 components of the 2 questionnaires.Conclusions/ImplicationsPreoperative, self-administration of SB and IS questionnaires is feasible. Overall, 65% of those with affirmative responses to ≥3 questions were at risk for OSA and associated with a disproportionate number of postoperative META in older patients. Additionally, risk of OSA identified by preoperative sleep questionnaires was associated with postoperative META among older adults. Use of clinical tools and OSA questionnaires may improve preoperative identification of META in this population.     

Evaluación participativa del territorio con enfoque de equidad: adaptación y validación de la Place Standard al contexto español

ObjectiveTranslation and cross-cultural adaptation to the Spanish context of the Place Standard tool to undertake participatory evaluations in place-based communities.MethodA back-translation method was used to obtain an adapted version of the original Place Standard tool. The translated version was reviewed by a multidisciplinary committee of experts and validated using the Delphi method.ResultsThe final version of the adapted Place Standards tool (Entornos de Vida in Spanish) consists of 14 dimensions and 99 items. 21% of the items presented semantic difficulties during the translation. Total consensus through the Delphi panel was reached on 72% of the items. The analysis resulted in changes to the wording, and organization of the items, and the inclusion of new or modified questions to reflect the characteristics of the Spanish context.ConclusionsThe validation of the Entornos de Vida tool will enable the evaluation of place-based communities characteristics/physical and socio-economic contexts in a participatory and equitable manner that focuses on social determinants of health. Its application in scenarios that take into account processes of local health action will support the practice of health promotion and equity, and centre the attention and action on the physical and socio-economic contexts with the aim to learn how places and municipal policies can affect health and well-being.
