Self-management in lower urinary tract symptoms: the next major therapeutic revolution

The potential role of a self-management intervention for benign prostate hyperplasia

OBJECTIVE

To tentatively evaluate the usefulness of self-management interventions in improving the lower urinary tract symptoms (LUTS) and quality of life (QoL) in patients with benign prostatic hyperplasia (BPH).

METHODS

Two-hundred twent-two men were recruited from a teaching hospital at Peking University from March 2008 to September 2009. They were referred by general practitioners to urologic outpatient departments because of BPH after 3-month administration of α-blockers. Participants were randomized to attend either a self-management program or undergo standard care. Difference of scores of International Prostate Symptom Score (IPSS) and BPH-specific QoL scale between 2 groups was analyzed at the enrollment period, and at the first week, third month, and sixth month.

RESULTS

All participants had been followed for 6 months. There was no significant difference in IPSS score and QoL score between the 2 groups at the enrollment period and first week, whereas at the third month and sixth month, the IPSS scores and QoL self-management interventional group scores were statistically significant lower than those of the standard care group.

CONCLUSION

Self-management intervention may be associated with decreased LUTS symptoms and may improve QoL in BPH patients with α-blocker administration.

Dietary, but not supplemental, intakes of carotenoids and vitamin C are associated with decreased odds of lower urinary tract symptoms in men

Lower urinary tract symptoms (LUTS) in men may be related to micronutrients involved in prevention of oxidative damage or cell growth and differentiation. We tested the hypothesis that carotenoid, vitamin A, and vitamin C intake were inversely associated with total LUTS, voiding, and storage symptoms. We conducted a cross-sectional multivariate analysis of 1466 men aged 30-79 y in the Boston Area Community Health survey (2002-2005), a population-based random sample survey. Data were collected by in-person interview and validated FFQ. Moderate-to-severe LUTS were defined using the American Urological Symptom Index and analyzed using multivariate logistic regression. Overall, men consuming greater dietary lycopene, β-carotene, total carotenoid, or vitamin A had ~40-50% decreased odds of LUTS compared with the lowest intake quartiles (e.g. β-carotene and storage symptoms, OR = 0.56, 95% CI = 0.39, 0.82; P-trend = 0.02). Interactions were observed between dietary iron and vitamin C or β-cryptoxanthin, whereby inverse associations with LUTS, particularly voiding symptoms, occurred only among men with moderate-to-high iron intake (P-interaction = 0.001). High-dose supplemental and total vitamin C were positively associated with LUTS (e.g. supplemental vitamin C ≥ 250 mg/d, OR = 1.83, 95% CI = 1.21, 2.77; P-trend = 0.02). An interaction between β-carotene and smoking status (P-interaction = 0.004) indicated greater odds of LUTS with higher β-carotene intake among current smokers. Results suggest that modifying consumption of carotenoids and vitamin C may influence LUTS in men.

Behaviour modification and benign prostatic hyperplasia: replacement for medications

PURPOSE OF REVIEW

Lower urinary tract symptoms due to benign prostatic hyperplasia (BPH) is a highly prevalent chronic disease. The cost impact of treatment is high. The field of behavioural treatments which could be suitable in the majority of uncomplicated patients has rarely been assessed. We summarize the recent knowledge and data from behavioural interventions chiefly the randomized controlled trial (RCT) of a self-management programme for BPH.

RECENT FINDINGS

The self-management RCT has revealed that a rigorously structured behavioural programme can significantly reduce lower urinary tract symptoms severity and decrease objective symptoms like nocturia, urgency and frequency compared with standard care alone. The elements of the programme and their behavioural framework are carefully defined. The basis of the programme's effectiveness is yet unknown, but may involve changes in bladder capacity rather than simple fluid management. The sphere of behavioural interventions for BPH is lacking and requires more research.

SUMMARY

Elements of the self-management programme are already being used in watchful waiting. Improving quality of life of patients with BPH through self-management will help patients and may reduce the financial burden on healthcare systems. The promotion of multidisciplinary team is a key step in implementing self-management strategies. With larger scale trials, the limitations raised and questions posed by the RCT can be further addressed.

Accountability for patient self-management of chronic conditions; ethical analysis and a proposal

Patient self-management (PSM) of varying portions of therapy for chronic illness is expanding. However, several current conditions of practice are ethically problematic. Standards remain process-oriented, and accountability for patient outcomes and quality of practice of both patient and provider is diffuse. PSM carries important benefits but largely unmonitored potential harms. Also, access to preparation for safe PSM appears to be skewed in favour of high socio-economic classes. This condition persists even though available evidence supports the conclusion that less advantaged patients with poor disease outcomes can be taught to self-manage, albeit they require more intensive and prolonged interventions. Routine clinical use of well-validated measurement instruments could serve to develop evidence-based standards of PSM, quality improvement and effective public policy. Development of a standard dataset would facilitate description of the effectiveness of existing programmes and comparison across programmes. Such reform will require investment in the development of instruments that measure patient ability to make sound clinical judgements and sustain PSM over changed disease and social conditions. It will take advantage of modem psychometric theory, which is increasingly necessary for building the empirical base for evidence-based healthcare.
