PRESHYON: THE PREVALENCE ON THE RISK OF OSA AMONG PATIENTS WITH UNCONTROLLED HYPERTENSION SEEN AT THE OUT-PATIENT DEPARTMENT OF THE UNIVERSITY OF THE PHILIPPINES, PHILIPPINE GENERAL HOSPITAL

Abstract

SESSION TITLE: Sleep Disorders Posters SESSION TYPE: Original Investigation Posters PRESENTED ON: October 18-21, 2020 PURPOSE: To determine the prevalence of the risk of Obstructive Sleep Apnea among patients with uncontrolled Hypertension (HTN) seen at the Out-Patient Department of the University of the Philippines-Philippine General Hospital METHODS: This is a cross-sectional study that enrolled 325 adult Filipino HTN patients seen at the outpatient department (OPD) of UP-PGH from January 2019 to July 2019. Participants also answered Berlin Questionnaire (BQ), Epworth Sleepiness Scale (ESS) and the St. Lukes Medical Center-Obstructive Sleep Apnea Clinical Score (SLMC-OSACS) for their OSA risk. Descriptive statistics were used to summarize the clinical characteristics of the patients. A chi-square test was used to analyze categorical data univariately. Logistics regression analysis was used to determine the association of the different independent variables with the outcome (dependent) variable. RESULTS: The risk of OSA was significantly high among uncontrolled HTN patients: 106 (60.7%) based on BQ (p<0.0001) and 68 (69.4%) based on SLMC-OSACS (p<0.0001). OSA risk among uncontrolled HTN was 6x higher (OR=5.69; 95% CI=3.49–9.28;p<0.0001) using the BQ and 4x higher (OR=3.70; 95% CI=2.19 – 6.26;p=<0.0001) using the SLMC-OSACS than those with controlled HTN. Daytime excessive sleepiness was not significantly associated. Other variables significantly associated with high risk OSA were BMI and other comorbidities. CONCLUSIONS: Among patients with hypertension, the risk of OSA based on the Berlin Questionnaire and SLMC-OSACS was significantly high among uncontrolled hypertension patients than those with controlled hypertension. Daytime excessive sleepiness noted with the ESS was not significantly associated with uncontrolled hypertension. Other demographic and clinical profile that were significantly associated with high risk OSA were BMI and other comorbidities (such as bronchial asthma, congestive heart failure) based on the SLMC-OSACS. CLINICAL IMPLICATIONS: Utilizing these sleep questionnaires and determining the risk for OSA among patients with uncontrolled hypertension will lead to early evaluation of OSA and complications. Locally this will aid in improving detection and provide more strategic management of uncontrolled hypertension to decrease associated cardiovascular events. This will guide our clinicians to prioritize patients who would benefit referral to sleep specialists DISCLOSURES: No relevant relationships by Jamie Chua, source=Web Response No relevant relationships by Angelica cruz, source=Web Response No relevant relationships by Maria Lowella De Leon, source=Web Response no disclosure on file for Manuel Jorge; No relevant relationships by Anna Katrina Tojino, source=Web Response
