Determinants of Seeking of Primary Care for Lower Urinary Tract Symptoms: The Krimpen Study in Community-Dwelling Men

The relationship between prevalence and severity of lower urinary tract symptoms (LUTS), and body mass index and mid-abdominal circumference in men in a resource-poor community in Southeast Nigeria: a cross-sectional survey

Background

There is paucity of information on the community-based prevalence and severity of lower urinary tract symptoms (LUTS) in men who are 40 years and older in the southeast region of Nigeria. This study seeks to determine the community-based prevalence of LUTS and the relationship between LUTS, and body mass index (BMI) and mid-abdominal circumference (MAC) in men.

Methods

An interviewer-administered, questionnaire-based survey. Three of nine settlement clusters were randomly selected while systematic random sampling of 1 in 3 eligible subjects was used to select participants. Analysis was done using SPSS® version 20.

Results

One thousand three hundred and nineteen duly completed questionnaires were analyzed. The respondents are within ages 40-92 years with mean age 54.2 ± 10.2 years, mean BMI 25.97 ± 4.18Kg/m² and mean MAC 89.80 ± 12.43 cm. Overall prevalence of LUTS is 20.2%. Nocturia at a prevalence of 19.2% is the most prevalent lower urinary tract symptom and also the earliest to manifest. LUTS prevalence and severity increases with increasing age. About 9.6% report moderate LUTS while 2.3% report severe LUTS. Storage LUTS are reported more frequently than voiding LUTS. LUTS did not vary significantly with BMI, MAC or Wealth-Index.

Conclusion

LUTS prevalence and severity vary with age, but not with BMI, MAC or Wealth-Index.

Undiagnosed cancer symptoms in the community: does poor quality of life influence the decision to seek help?

PURPOSE

Although a cancer diagnosis is linked with decrements to quality of life (QoL), it is unknown exactly when QoL starts to deteriorate, and whether this occurs during the pre-diagnostic pathway. This study aimed to examine QoL during this phase, and in addition investigate whether QoL levels influence decisions about seeking professional help. This is important, because early diagnosis is linked to lower cancer mortality rates.

METHODS

Working alongside a Cancer Research UK Roadshow in socially deprived communities, the recent QoL of adult visitors was assessed, before attending primary care. Using a cross-sectional design, we compared QoL in those presenting a potential cancer symptom/sign, with others seeking lifestyle advice to reduce cancer risk. Self-reported QoL (WHOQOL-BREF), and intention to seek help, were measured.

RESULTS

Of 107 recruited, 50% were men. The potential cancer symptom group reported significantly poorer general QoL and psychological QoL, than lifestyle controls. Prior poorer physical QoL predicted stronger intentions to consult a general practitioner (GP) in the next 2 weeks, when controlling for symptom presence.

CONCLUSIONS

QoL is poorer for those with potential cancer symptoms, before they first seek advice from primary care. Poorer physical QoL is associated with stronger intentions to make a GP appointment. An implication for longer term health is that if public awareness about the impact of symptoms on QoL was raised, this could provide an impetus to seek help.

The health-related quality of life of Chinese patients with lower urinary tract symptoms in primary care

PURPOSE

The aim of this study was to evaluate the health-related quality of life (HRQOL) of Chinese primary care patients with lower urinary tract symptoms (LUTS).

METHODS

Five hundred and nineteen primary care subjects with LUTS completed a structured questionnaire containing the International Prostate Symptom Score, the adapted Incontinence Impact Questionnaire-7, the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, the Chinese (HK) SF-12 Health Survey Version 2 (SF-12 v2) and the Depression, Anxiety and Stress Scale-21.

RESULTS

LUTS patients had poorer HRQOL for the General Health and the Vitality domains and lower Physical Component Summary scores, but better HRQOL for the Role Emotion domain than the adjusted Hong Kong population norms. Clinical factors associated with poorer HRQOL measured by the SF-12 v2 included having more severe LUTS and having more severe depressive, anxiety and stress symptoms. Socio-demographic factors associated with poorer SF-12 v2 were consistent with those found in the general populations. Clinical and socio-demographic factors associated with poorer HRQOL assessed by condition-specific measures included having more severe LUTS (excluding intermittency and straining), the presence of mixed urinary incontinence, having more severe anxiety and stress symptoms, younger age, being not married, being in employment and having a lower household income.

CONCLUSIONS

LUTS had substantial negative impact on patients' overall health perception and global well-being in Chinese population. A decline in HRQOL might be a key determinant for Chinese patients with LUTS to seek treatment. Patients with nocturia, frequency, urgency or mixed urinary incontinence and younger patients deserve more treatment attention because they appear to have poorer HRQOL.

Pelvic ultrasound evaluation for benign prostatic hyperplasia: prediction of obstruction

Global improvements in water quality, management of infectious diseases, and other medical therapeutics have resulted in a growing population of healthy aging men. One obligate anatomic consequence of aging for these men is the development of benign prostatic hyperplasia (BPH) with secondary bladder outlet obstruction. Although the voiding symptoms associated with the change in bladder health over time predominantly impact the quality of a man's daily experience, there are also significant medical consequences of BPH that require intervention. It is a challenge to distinguish men who are at risk for these medical consequences from the much larger population of older men with voiding symptoms (lower urinary tract symptoms, LUTS). A variety of national guidelines have been developed to establish a diagnostic paradigm for meeting this challenge, but all suffer from inadequate sensitivity for the early identification of men at risk for permanent bladder injury. It is likely that the application of a thorough pelvic ultrasound designed to identify the pertinent anatomic aspects of both the bladder and prostate will improve the sensitivity of these diagnostic paradigms, with subsequent improvement in the outcomes for men with BPH/LUTS.

The Long-Term Outcome of Medical Therapy for BPH

OBJECTIVES

The lack of cure with medical therapy implies life-long treatment emphasising the need for a thorough understanding of the long-term outcome. We review the natural history, markers for progression, placebo effect, efficacy, pharmacoeconomic aspects, and preventive measures.

METHODS

Literature review with particular reference to long-term controlled studies using plant extracts, alpha1-blockers, 5alpha-reductase inhibitors (5-ARIs), and combination therapy.

RESULTS

There is a long-lasting (>or=12 mo) placebo response of symptoms (20% decrease) and maximum flow rate (10% rise). The five long-term controlled trials of plant extracts are inconclusive and therefore their role in contemporary medical management is still controversial. The alpha1-blockers provide fast amelioration of symptoms yet have no relevant impact on the risk of acute urinary retention or surgery. Combination therapy should be reserved for moderately or severely symptomatic patients with a high risk of progression; in the majority of patients the alpha1-blocker can be safely stopped after 6-12 mo. The preventive use of 5-ARIs in men with no or mild symptoms at risk of progression is scientifically sound yet not generally accepted mainly for economic reasons.

CONCLUSIONS

A sharp contrast exists between the duration of the longest controlled trial (4.5 yr) and the situation in real life with treatment periods up to one or two decades of life. Real-life and registry data will be the only source of this important information in the future.

Simple case definition of clinical benign prostatic hyperplasia, based on International Prostate Symptom Score, predicts general practitioner consultation rates

OBJECTIVES

To determine which case-definition of clinical benign prostatic hyperplasia (BPH) has the best predictive value for general practitioner visits for lower urinary tract symptoms (LUTS) suggestive of BPH. The incidence and prevalence rates of general practitioner visits for LUTS were also determined.

METHODS

A longitudinal, population-based study from 1995 to 2003 was conducted among 1688 men aged 50 to 78 years old. Data were collected on physical urologic parameters, quality of life, and symptom severity as determined from the International Prostate Symptom Score. Information on health-care-seeking behavior of all participants was collected from the general practitioner (GP) record using a computerized search engine and an additional manual check of the electronically selected files.

RESULTS

The incidence and prevalence rate of the men at risk was 19.6% and 14.0%, respectively, and these rates increased with age. For sensitivity and the positive predictive value, the case-definition of clinical BPH as an International Prostate Symptom Score greater than 7 had the best predictive value for GP visits for LUTS within 2 years after baseline.

CONCLUSIONS

Because only marginal improvement (greater specificity but lower sensitivity) in the prediction of GP visits for LUTS was possible by adding information on prostate volume and flow, for the prediction of future GP visits for LUTS suggestive of BPH, we suggest that the International Prostate Symptom Score questionnaire be used and that estimation of the prostate volume and flow is not required.
