RESUMO

OBJECTIVES: The aim of this quality assurance project was to determine how many patients who qualified for intermittent auscultation (IA) in labour were actually monitored by intermittent auscultation. A secondary objective was to assess whether the rate of IA use depended on maternal BMI. METHODS: We performed a retrospective chart review in a sample of women who received obstetrical care at Kingston General Hospital over one year from July 31, 2012. Eligibility was determined using the inclusion and exclusion criteria outlined by the hospital's guideline on intermittent auscultation. RESULTS: Two hundred seven of 244 charts analyzed in this review qualified for IA. The mean age of women in the study was 29.3 (range 17 to 41) years. Their mean gestational age was 39.6 (range 37 to 42) weeks. Fifty-six percent (116/207) of the eligible women actually had IA. Forty-seven percent of obese women who were eligible (47/100) had IA, compared with 64.4% of overweight women (58/90). This difference (17.4%) was statistically significant (P = 0.019, Fisher exact test). CONCLUSION: Fifty-six percent (116/207) of women with low risk pregnancies who were deemed eligible to have IA rather than electronic fetal heart rate monitoring actually had IA. Obese women were less likely to have IA than overweight women. More research is required regarding barriers to using IA in eligible women in our institution and elsewhere.


Objectifs : Ce projet d'assurance de la qualité avait pour but de déterminer le nombre des patientes répondant aux critères nécessaires à la mise en œuvre d'une auscultation intermittente (AI) pendant le travail qui ont bel et bien fait l'objet d'un tel monitorage. Son objectif secondaire était de déterminer si le taux d'utilisation de l'AI dépend de l'IMC maternel. Méthodes : Nous avons mené une analyse de dossiers rétrospective auprès d'un échantillon de femmes ayant reçu des soins obstétricaux au Kingston General Hospital sur une période d'un an à partir du 31 juillet 2012. L'admissibilité a été déterminée au moyen des critères d'inclusion et d'exclusion décrits par les lignes directrices de l'hôpital sur l'auscultation intermittente. Résultats : Deux cent sept des 244 dossiers analysés dans le cadre de cette analyse ont répondu aux critères nécessaires à la mise en œuvre d'une AI. L'âge moyen des femmes étudiées était de 29,3 ans (plage : de 17 à 41 ans). Leur âge gestationnel moyen était de 39,6 semaines (plage : de 37 à 42 semaines). Cinquante-six pour cent (116/207) des femmes admissibles ont bel et bien fait l'objet d'une AI. Quarante-sept pour cent des femmes obèses admissibles (47/100) ont fait l'objet d'une AI, par comparaison avec 64,4 % des femmes présentant une surcharge pondérale (58/90). Cette différence (17,4 %) était significative sur le plan statistique (P = 0,019, test exact de Fisher). Conclusion : Cinquante-six pour cent (116/207) des femmes qui connaissaient une grossesse exposée à de faibles risques et que l'on estimait être admissibles à la mise en œuvre d'une AI plutôt qu'à celle d'un monitorage fœtal électronique ont bel et bien fait l'objet d'une AI. Les femmes obèses étaient moins susceptibles de faire l'objet d'une AI que les femmes présentant une surcharge pondérale. La tenue d'un plus grand nombre de recherches s'avère requise au sujet des obstacles à l'utilisation de l'AI chez les femmes admissibles, tant au sein de notre établissement qu'ailleurs.

RESUMO

BACKGROUND: The risk of stroke in patients with asymptomatic carotid stenosis (ACS) is now so low that it is important to have methods to identify those patients most likely to benefit from intervention, or who may require special consideration in choice of medical therapy. We studied the prediction of stroke, death or transient ischemic attacks (stroke/death/TIA) in patients with ACS by intracranial arterial stenosis, and microemboli on transcranial Doppler (TCD), and the effect of diabetes mellitus on microemboli, intracranial stenosis and risk of events. METHODS: Patients with ACS > 60% by Doppler ultrasound were recruited from the Stroke Prevention Clinic of University Hospital, London, Canada. All 339 participants underwent TCD for detection of intracranial stenosis and detection of microemboli, and carotid ultrasound to measure extracranial stenosis and total carotid plaque area. Participants were followed for three years, to determine the risk of stroke/death/TIA. RESULTS: Stroke/death/TIA occurred in 38% of patients with microemboli versus 10% without (p=0.0001), and in 18% of patients with intracranial stenosis, versus 10% without (p=0.042). Diabetics were significantly more likely to have intracranial stenosis (45% vs. 29%, p =0.014), microemboli (38% vs. 10%, p <0.0001), and had significantly higher risk of stroke/death/TIA over three years (21% vs. 11% without; p=0.024). Survival free of stroke, TIA or death was significantly better without microemboli or intracranial stenosis (p<0.0001). CONCLUSIONS: Diabetes, microemboli and intracranial stenosis predicted higher risk of stroke, death or TIA than did extracranial stenosis or total plaque area; diabetics may need more intensive therapy.
