Medication adherence in older clinic patients with hypertension after Hurricane Katrina: implications for clinical practice and disaster management.

ABSTRACT: In post-disaster situations, additional barriers may reduce antihypertensive medication adherence.Between November 2005 and August 2006, 210 hypertensive patients receiving care at a multispecialty group practice in New Orleans completed a structured questionnaire. Antihypertensive medication adherence was measured with the Hill-Bone medication compliance subscale. In a subset of patients, data on difficulties patients encountered with blood pressure medications in the aftermath of Hurricane Katrina were collected.: Seventy-six percent of patients reported damage to their residence and 46% of patients had less-than-perfect medication adherence. After multivariate adjustment, less than perfect medication adherence postdisaster was more common among people aged <65 years (prevalence ratio = 1.37; 95% confidence interval: 1.03-1.82) and non-whites (1.32; 95% confidence interval: 1.02-1.71). Uncontrolled blood pressure (systolic/diastolic > or =140/> or =90 mm Hg) was more common in those with less-than-perfect adherence than their counterparts with perfect adherence (51% versus 42%, respectively). In addition, 7% of patients reported not bringing their blood pressure medications when they evacuated, 28% ran out of blood pressure medications, 16% reported difficulties getting medications filled, and 28% reported a blood pressure medication change postdisaster.Opportunities exist to improve disaster planning and prescription refill processes and increase medication adherence and hypertension control postdisasters.

Project description:BackgroundSelf-care practices for patients with hypertension include adherence to medication, use of blood pressure self-monitoring and use of complementary and alternative therapies (CAM) The prevalence of CAM use and blood pressure self-monitoring have not been described in a UK secondary care population of patients with hypertension and their impact on adherence to medication has not been described. Adherence to medication is important for blood pressure control, but poor adherence is common. The study aimed to determine the prevalence of self-care behaviours in patients attending a secondary care hypertension clinic.MethodsCross-sectional questionnaire survey. 196 patients attending a secondary care hypertension clinic in a teaching hospital serving a multiethnic population, Birmingham, UK.Main outcome measuresPrevalence of use of CAM, home monitors, adherence to anti-hypertensive medication.ResultsCAM use in previous 12 months was reported by 66 (43.1%) respondents. CAM users did not differ statistically from non-CAM users by age, gender, marital status or education. Vitamins, prayer a dietary supplements were the most commonly used CAM. Nine (12.7%) women reported using herbal CAM compared to one man (1.2%), (p = 0.006). Ten (6.7%) respondents reported ever being asked by a doctor about CAM use. Perfect adherence to anti-hypertensive medication was reported by 26 (44.8%) CAM-users and 46 (60.5%) non-CAM users (p = 0.07). Being female and a CAM user was significantly associated with imperfect adherence to anti-hypertensive medication. Older and white British respondents were significantly more likely to report perfect adherence. Blood pressure monitors were used by 67 (43.8%) respondents, which was not associated with gender, CAM use or adherence to medication.ConclusionHypertensive patients use a variety of self-care methods, including CAM, home blood pressure monitors, and adherence to prescribed medication. This study found the prevalence of CAM use in hypertensive patients was higher than in the UK population. It is important to acknowledge the self-care behaviour of hypertensive patients, in order to assess potential harm, and encourage effective methods of self-care.

Project description:BackgroundPoor adherence to antihypertensive drugs is a major cause of unsatisfactory blood pressure control. Hypertension doctors play an integral role in improving medication adherence in hypertensive patients. Although most existing studies have recognized the status quo and influencing factors of medication adherence, little attention has been paid to hypertension doctors' awareness and practice in hypertension management. Therefore, in this study, we aimed to investigate hypertension doctors' awareness and practice of medication adherence in hypertensive patients.MethodsThis is a cross-sectional survey. A self-reported questionnaire was developed and sent to hypertension doctors in Hunan province, China, between May 1, 2022 and July 1, 2022. Univariate and generalized linear models were used to identify the factors influencing hypertension doctors' awareness and practice. The correlation between awareness and practice was determined using Spearman's correlation coefficient.ResultsIn total, 236 valid questionnaires were collected (valid response rate, 73.5%). Of the respondents, 44.1% were chief physicians and 64.4% were females. Approximately half of the respondents were ≥40 years old and had over 14 years of working experience. Most respondents (87.7%) did not have hypertension, but 54.2% had a family history of hypertension. The average awareness and practice scores were 29.8 ± 8.8 and 39.4 ± 7.1, respectively, out of 50, with higher scores indicating higher levels of awareness or practice. More hypertension consultations and more antihypertensive prescriptions issued were associated with better awareness and practice among respondents (ps < 0.05). Respondents with higher education and professional titles had higher awareness (ps < 0.05). Moreover, respondents with 6-13 years of work experience had better practice than those with <5 years of work experience (p = 0.017). There was a significant correlation between hypertension doctors' awareness and practice of medication adherence in hypertensive patients (R = 0.682, p < 0.001). These findings indicate that misconceptions persist in hypertension doctors' awareness and practice of patient medication adherence.ConclusionHypertension doctors lack sufficient and correct awareness and practice of medication adherence in hypertensive patients.
