Quality of care of hypertension in three clinical settings in Jamaica

RESUMO

To determine quality of monitoring and control of hypertension in Jamaica, 756 records of patients, aged > 30 years, attending a public general clinic (PUBMC) (n=500), a special hypertension clinic (SPMC) (n=119) and a private group general clinic (PRMC) (n=137), for more than one year, were reviewed. Duration of follow-up varied among clinics with the longest mean follow-up at PRMC (10.8 years) compared to 6.1 years and 4.7 years at the PUBMC and SPMC respectively. Mean age was greatest at the PUBMC (60 yrs) compared to 53 years in the SPMC and 50 years in the PRMC (p < 0.001). Sex distribution differed among clinics with 15 percent men in the PUBMC, 34 percent in the SPMC and 54 percent in the PRMC (p < 0.001). Over 92 percent of patients had blood pressure (BP) recorded at least once in the 12-month review period. Hypertension was defined as being prescribed antihypertensive medication in clinic records. By this definition 98 percent SPMC patients were hypertensive, compared to 87 percent PUBMC and 80 percent PRMC. Using BP < 160 / 95mmHg, the PRMC was 0.57 (0.34-0.97) compared to the other two clinics after adjustments for age, clinic type, duration of follow-up and gender. Only age was a significant covariate with older patients at greater risk of poor control. Only 18 percent of hypertensives were controlled to BP < 140 / 90mmHg with no difference among clinics. Diuretics were the commonest agent used at the PUBMC (76 percent) and SPMC (86 percent) followed by a-methyldopa, 41 percent and 27 percent, respectively. These agents were less commonly prescribed at the PRMC than at the other clinics (45 percent diuretics and 8 percent a-methyldopa, p < 0.001 for both agents compared to other clinics). PRMC used more angiotensin converting enzyme inhibitors 38 percent, compared to SPMC 23 percent and PUBMC 1 percent (p < 0.001). Between 9 percent and 15 percent of patients at the PUBMC and PRMC had recorded data on smoking and alcohol use compared to 69 percent at the SPMC. A record of body weight was found in 99 percent at SPMC compared to 82 percent at PRMC and 33 percent at PUBMC (p < 0.001). Surveillance for complications differed for proteinuria (PRMC 33 percent, PUBMC 15 percent, SPMC 15 percent) and fundoscopy (PUBMC 0 percent, PRMC 3 percent, SPMC 43 percent). These results show very limited adherence to recommended hypertension treatment guidelines in all three settings.
