The effective tool for self-assessment of adherence to treatment in patients with benign prostatic obstruction and overactive bladder symptoms

Abstract Purpose: Study of validity of the Medication Adherence Self-Report Inventory (MASRI) for use in clinical practice to treat patients with benign prostatic obstruction (BPO) accompanied with overactive bladder (OAB) symptoms. Methods: During 12 weeks of the randomized study, 452 patients with BPO and OAB symptoms (mean age of 61.3 (12.7)) were studied for adherence to the treatment with Tamsulosin, Solifenacin and Trospium using the MASRI. External monitoring instruments included the Brief Medication Questionnaire (BMQ) and the visual remaining pill count. The state of the prostate gland and the lower urinary tract was monitored using questionnaires I-PSS, OAB Awareness Tool, uroflowmetry and voiding diaries. Result: Correlation between the percentage of men non-adherent to treatment (MASRI) and the percentage of patients having a belief barrier on the screen of the BMQ was r = 0.89, p ≤0.05, r = 0.92, p ≤0.01, r = 0.85, p ≤0.05, a number of missed doses on the Regimen Screen of the BMQ was r = 0.79; p ≤0.05; r = 0.81; p ≤0.05; r = 0.75, p ≤0.05, a number of non-adherent patients according to the BMQ was r = 0.83 (p ≤0.05), r = 0.88 (p ≤0.05), r = 0.79, p ≤0.05, the results of the pill count were r = 0.65–0.76; p ≤0.05-0.01. These data confirm high validity of the MASRI. Conclusion: The MASRI is a valid tool for rapid assessment of adherence to treatment of patients with BPO and OAB receiving Tamsulosin and antimuscarinic drugs and may be recommended for use in clinical practice.

Treatment compliance of working persons to high-dose antimuscarinic therapies: a randomized trial

Aim: The aim of this work was to study the factors affecting the stability of working patients in antimuscarinic (AM) drug treatment. Background: The prevalence of urge urinary incontinence (UUI) is an average of between 8.2% and 16.0% of the population. UUI is a condition that adversely affects the health-related quality of life. The first-line therapy in managing UUI is AM treatment. Methods: In 1006 patients between 18 and 60 years old (627 women, 379 men, mean age 69.4) who received AM treatment for one year, the possible demographic, socioeconomic and health factors influencing compliance were studied. Also, the functional state of the lower urinary tract (LUT) was studied in this randomized, prospective survey. The study instruments were the documents of employers, tax offices, outpatient records, OABq-SF (overactive bladder - short form) questionnaires, MOS SF-36 (Medical Outcomes Study short form-36), voiding charts, and uroflowmetry data. Results: The compliance to AM treatment within 6 months was retained in 49.5% patients; during the year, in 32.3% of patients. The average time for reaching the 30-day break in taking trospium was 194 days. In the course of the experiment it was revealed that compliance to AM treatment was significantly higher in patients taking solifenacin and trospium in high dosages (p ⩽ 0.01, p ⩽ 0.05), suffering from severe symptoms of urgency (p ⩽ 0.01), and having a low level of side effects (p ⩽ 0.01). A satisfactory level of compliance is characteristic of patients with a high level of monthly and annual income (p ⩽ 0.01, p ⩽ 0.01), a low percentage of expenses to AM (p ⩽ 0.05), and rarely changing employers (p ⩽ 0.05). In addition, the compliance to treatment is higher in older adults (p ⩽ 0.05), living in the urban district (p ⩽ 0.01), and working in educational (p ⩽ 0.05) and health (p ⩽ 0.01) institutions, having a high level of the indices of Social Functioning (p ⩽ 0.05), Role-Emotional (p ⩽ 0.05), and Mental Health (p ⩽ 0.01). Conclusion: As a result of this study, under the control of the objective functional state of LUT, the influence of various factors on the patients’ stability in the treatment with AM drugs was revealed.

Self-assessment of treatment compliance with antimuscarinic drugs and lower urinary tract condition among women with urinary incontinence

AimOur aim was to determine the efficiency of the Medication Compliance Self-Report Inventory (MASRI) in self-reporting antimuscarinic drug treatment compliance among women with urinary incontinence (UI).Materials and methodsThe study assessed 347 women aged 18–65 (averaging 49.7) years with more than one urinary incontinence (UI) episode per day. Treatment compliance was tested at the beginning and at weeks 4, 8, and 12 using the MASRI, the Brief Medication Questionnaire (BMQ), and visual pill counts. The MASRI’s constructive, concurrent, and discriminate validity was studied in comparison with an external standard that uses the chi-square and Spearman coefficient. Receiver operating characteristic (ROC) analysis was performed to identify optimum MASRI cutoffs that would predict noncompliance. Furthermore, the functional condition of the lower urinary tract was tested using voiding diaries, uroflowmetry, and cystometry.ResultThe correlation between the percentage of noncompliant women according to the MASRI, and individuals with a belief barrier with respect to the BMQ screen was r = 0.81 (p ≤0.05), r = 0.84 (p ≤0.05), and r = 0.79 (p ≤0.05). The correlation between the percentage of noncompliant women according to the MASRI and of women who missed >20% of their doses according to the Regimen Screen of the BMQ was r = 0.79, p ≤0.05, r = 0.82, p ≤0.01, r = 0.77, and p ≤0.05 at the control points. Finally, the percentage of noncompliant patients who self-reported correctly according to the MASRI data compared with the BMQ was 95.6%, 95.7%, and 96.6% at the control points.ConclusionThe MASRI entails acceptable validity for accurately predicting treatment compliance with antimuscarinic drugs among women who have had UI for >3 months.

Comprehensive Assessment of Compliance with Antimuscarinic Drug Treatment in the Case of Urge Urinary Incontinence of Older Patients

AIM To investigate the heterogeneous factors affecting the stability of patients older than 60 years in the UI treatment with Antimuscarinics. BACKGROUND The prevalence of Urge Incontinence (UI) in older persons reaches 29.3%. The symptoms of urinary incontinence in older people reduce the health related life quality. MATERIALS AND METHODS In 1257 patients over 60 years (857 (68.2%) women - average age 67.8, 400 (31.8%) men - 71.4), who received AM for one year, demographic, socio-economic and health parameters were studied. OABq-SF questionnaires, MOS SF-36, urination diaries, uroflowmetry, income information from the tax offices and outpatient records were used. RESULT The compliance to AM treatment within 6 months was retained in 44.2%, and within the year - 26.8% of older patients. At least 40% of the total number of patients refused to continue the treatment for medical reasons. The persons taking Solifenacin (p≤ 0.01), Trospium (p≤ 0.05), or Darifenacin (p≤ 0.05), suffering from severe UI symptoms (p≤ 0.01), and experiencing minor side effects (p≤ 0.01), well-informed about UI treatment methods (p≤ 0.01) prevailed among the treatment compliant patients. At least 20.4% of the patients discontinued their treatment due to economic reasons. The persons with significantly larger annual income (p≤ 0.05) and annual medical cost (p≤ 0.01) prevailed among the treatment compliant patients. About 12.2% of the patients stopped their treatment for reasons related to the social background and psychological status. CONCLUSION In this experiment, we found that AM treatment compliance in older patients, in addition to medical parameters and health conditions, is largely affected by the economic as well as social, demographic and psychological factors. The study results can be claimed by practitioners involved in correcting UI symptoms in older people.
