RESUMEN
BACKGROUND: Patients in methadone maintenance treatment (MMT) may develop age-related medical problems. Objective: To compare hypertension prevalence and its risk factors between two MMT clinics, having similar treatment guidelines, but different characteristics, one from Tel Aviv (TA) and one from Las Vegas (LV). METHODS: Prevalence of hypertension (systolic ≥140 and or diastolic ≥90 mmHg BP) among all current 291 MMT patients in TA and 180 patients in LV were studied, including body mass index (BMI), drugs in urine, sociodemographic, and addiction history data. RESULTS: Hypertension prevalence was comparable in TA (35.4%) and LV (34.4%), however TA patients were older (55.9 ± 9.5 vs. 45.5 ± 13.3, p < 0.001), with fewer females (22 vs. 42.2%, p < 0.001), fewer obese (BMI ≥30) (24 vs. 40.9%, p < 0.001), higher cocaine (21 vs. 7.8%, p < 0.001), and lower cannabis (14.1 vs. 32.4%, p < 0.001) and amphetamines (0 vs. 33.5%) users. Logistic regression found higher BMI to characterize hypertension in both clinics, but in TA also negative urine cocaine, benzodiazepine, and opioids screen, while in LV older age (≥50 y), male gender, and negative urine cannabis screen. CONCLUSIONS: While TA was characterized with older patients, LV patients had a comparable hypertension rate, as obesity was more prevalent. No drug use was accompanied by higher BMI in TA and therefore associated with hypertension. Weight reduction, hypertension detection and treatment are recommended.
RESUMEN
BACKGROUND: Although methadone maintenance treatment (MMT) guidelines are well established, patients' characteristics and outcome change over time may be affected by the legality of cannabis. OBJECTIVE: To study trend changes between two clinics over 20 years from Las Vegas (LV) and 27 years from Tel Aviv (TA). METHODS: Patients' characteristics at admission, including drugs in urine at first and 13th month were obtained from their medical charts. Changes by year of admission and cumulative retention were analyzed. RESULTS: The LV MMT clinic (1724 patients) had a lower one-year retention rate compared to the TA MMT clinic (1014 patients) (46.4% vs. 74.4%, respectively, p < 0.0005), and a higher rate of opioid stop after one year (75.9% vs. 68.8%, respectively, p = 0.003). The age at MMT admission and the retention rates decreased in LV and increased in TA. The prevalence of cannabis and benzodiazepine misuse on MMT admission increased in LV with no change recorded in TA. Cocaine on MMT admission decreased in LV and increased in TA, while amphetamine use increased in LV and decreased in TA. Cox models multivariate analyses found cannabis on admission to predict shorter retention in LV (as younger age male and amphetamines), and cannabis after one year in TA (as did cocaine and opiates after one year and BDZ on admission). CONCLUSION: Although cannabis prevalence increased only in LV where it was legalized, it was associated with poor outcomes in both clinics. Younger age, a known poor outcome predictor, may be related to decreased retention in LV.
