Decisions about medication use and cancer screening across age groups in the United States

OBJECTIVE

To describe decision process and quality for common cancer screening and medication decisions by age group.

METHODS

We included 2941 respondents to a national Internet survey who made at least one decision about colorectal, breast, and prostate cancer screening, blood pressure or cholesterol medications. Respondents were queried about decision processes.

RESULTS

Across the five decisions considered, decision process scores were similar (and generally low) across age groups for medication and cancer screening, indicating that all groups had poor involvement in medical decision making. Overall knowledge scores were low across age groups, with elderly (75+) having slightly higher knowledge about medications vs. younger respondents. Elderly respondents reported similar goals and concerns when making decisions, though placed greater importance of having peace of mind from a normal result for cancer screening vs. younger respondents.

CONCLUSION

Across age groups, respondents reported poor decision processes about common medications and cancer screening, despite little evidence of benefit for some interventions (cancer screening, cholesterol lowering medicines in low risk elderly) and possibility of harm in the elderly.

PRACTICE IMPLICATIONS

Particular care should be taken to help patients understand both benefit and risk of screening tests and routine medications.

Pregabalin for the treatment of men with chronic prostatitis/chronic pelvic pain syndrome: a randomized controlled trial

BACKGROUND

Evidence suggests that the urogenital pain of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) may be neuropathic.

METHODS

This randomized, double-blind, placebo-controlled trial was conducted across 10 tertiary care centers in North America to determine whether pregabalin, which has been proved effective in other chronic pain syndromes, is effective in reducing CP/CPPS symptoms. In 2006-2007, 324 men with pelvic pain for at least 3 of the previous 6 months were enrolled in this study. Men were randomly assigned to receive pregabalin or placebo in a 2:1 ratio and were treated for 6 weeks. Pregabalin dosage was increased from 150 to 600 mg/d during the first 4 weeks. The primary outcome was a 6-point decrease in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) total score. Multiple secondary outcomes were assessed.

RESULTS

Of 218 men assigned to receive pregabalin, 103 (47.2%) reported at least a 6-point decrease in the NIH-CPSI total score at 6 weeks compared with 35.8% (38 of 106 men) assigned to receive placebo (P = .07, exact Mantel-Haenszel test, adjusting for clinical sites). Compared with the placebo group, men assigned to receive pregabalin experienced reductions in the NIH-CPSI total score and subscores (P < .05), a higher Global Response Assessment response rate (31.2% and 18.9%; P = .02), and improvement in total McGill Pain Questionnaire score (P = .01). Results for the other outcomes did not differ between groups.

CONCLUSION

Pregabalin therapy for 6 weeks was not superior to placebo use in the rate of a 6-point decrease (improvement) in the NIH-CPSI total score in men with CP/CPPS.

A survey of primary care physician practices in the diagnosis and management of women with interstitial cystitis/painful bladder syndrome

OBJECTIVES

To describe the practice patterns among primary care physicians' (PCPs) managing patients with symptoms suggestive of interstitial cystitis/painful bladder syndrome (IC/PBS).

METHODS

We developed a clinical vignette describing a woman with typical IC/PBS symptoms to elicit questions about etiology, management strategies, and familiarity with this syndrome. We mailed the questionnaire to 556 PCPs, including academicians and community physicians, in Boston, Los Angeles, and Chicago.

RESULTS

We received 290 completed questionnaires (response rate, 52%). Nineteen percent of respondents reported they had "never" seen a patient like the one described in the vignette. Two-thirds of respondents correctly identified the hallmark symptom of IC/PBS (bladder pain/pressure). Regarding etiology, 90% correctly indicated that IC/PBS was a noninfectious disease, 76% correctly reported that it was not caused by a sexually transmitted infection, and 61% correctly indicated that it was not caused by a psychiatric illness. Common treatments included antibiotics and nonsteroidal anti-inflammatory agents. Referrals were often made to a specialist.

CONCLUSIONS

Although most PCPs indicate familiarity with IC/PBS, they manage the condition infrequently. They also appear to have significant knowledge deficits about the clinical characteristics of IC/PBS, and they indicate variable practice patterns in the diagnosis and treatment of the condition. Educational efforts directed at PCPs will likely improve the care of patients with IC/PBS.

Prostate cancer screening decisions: results from the National Survey of Medical Decisions (DECISIONS study)

BACKGROUND

Guidelines recommend informing patients about the risks and benefits of prostate cancer screening. We evaluated the medical decision-making process for prostate-specific antigen (PSA) testing.

METHODS

We conducted a telephone survey of a randomly selected national sample of 3010 English-speaking US adults 40 years and older. Included in the survey were 375 men who had either undergone or discussed (with health care providers [HCPs]) PSA testing in the previous 2 years. We asked subjects about sociodemographic characteristics, prostate cancer screening discussion features, prostate cancer knowledge, and the importance of various decision factors and sources of information.

RESULTS

Overall, 69.9% of subjects discussed screening before making a testing decision, including 14.4% who were not tested. Health care providers most often (64.6%) raised the idea of screening, and 73.4% recommended PSA testing. Health care providers emphasized the pros of testing in 71.4% of discussions but infrequently addressed the cons (32.0%). Although 58.0% of subjects felt well-informed about PSA testing, 47.8% failed to correctly answer any of the 3 knowledge questions. Only 54.8% of subjects reported being asked for their screening preferences. An HCP recommendation (odds ratio, 2.67; 95% confidence interval, 1.08-6.58) was the only discussion characteristic associated with testing. Valuing HCP information was also associated with testing (odds ratio, 1.26; 95% confidence interval, 1.04-1.54).

CONCLUSIONS

Recommendations and information from HCPs strongly influenced testing decisions. However, most prostate cancer screening decisions did not meet criteria for shared decision making because subjects did not receive balanced discussions of decision consequences, had limited knowledge, and were not routinely asked for their preferences.

Validation of a modified National Institutes of Health chronic prostatitis symptom index to assess genitourinary pain in both men and women

OBJECTIVES

To date, separate condition-specific instruments have been used to assess severity of symptoms, in men and women with urological pain conditions. We developed a single instrument that can be used to assess treatment response in clinical trials and cohort studies that involve both genders.

METHODS

We developed the Genitourinary Pain Index (GUPI) by modifying and adding questions to the National Institutes of Health-Chronic Prostatitis Symptom Index. To assess discriminant validity, concurrent validity, and reliability, we administered the GUPI to 1653 men and 1403 women in a large managed care population. To assess responsiveness, we administered the GUPI to 47 men and women who completed a National Institutes of Health-sponsored trial of pelvic floor physical therapy.

RESULTS

The GUPI discriminated between men with chronic prostatitis or interstitial cystitis, those with other symptomatic conditions (dysuria, frequency, chronic cystitis), and those with none of these diagnoses (P <.05). It also discriminated between women with interstitial cystitis, those with incontinence, and those with none of these diagnoses (P <.05). The GUPI demonstrated good internal consistency within subscale domains, and GUPI scores correlated highly with scores on the Interstitial Cystitis Symptom Index and Problem Index. The GUPI was highly responsive to change, and the change in score was similar in both male and female responders. A reduction of 7 points robustly predicted being a treatment responder (sensitivity 100%, specificity 76%).

CONCLUSIONS

The GUPI is a valid, reliable, and responsive instrument that can be used to assess the degree of symptoms in both men and women with genitourinary pain complaints.

Rescoring the NIH chronic prostatitis symptom index: nothing new

The NIH-Chronic Prostatitis Symptom Index (NIH-CPSI) is a commonly used 13-item questionnaire for the assessment of symptom severity in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). For each item, score ranges are 0–1 (6 items), 0–3 (2 items), 0–5 (3 items), 0–6 (1 item), and 0–10 (1 item). This scoring system is straightforward, but items with wider score ranges are de facto weighted more, which could adversely affect the performance characteristics of the questionnaire. We rescored the NIH-CPSI so that equal weights were assigned to each item, and compared the performance of the standard and rescored questionnaires using the original validation dataset. Both the original and revised versions of the scoring algorithm discriminated similarly among groups of men with chronic prostatitis (n=151), benign prostatic hyperplasia (n=149), and controls (n=134). Internal consistency of the questionnaire was slightly better with the revised scoring, but values with the standard scoring were sufficiently high (Cronbach’s alpha ≥0.80). We conclude that although the rescored NIH-CPSI provides better face validity than the standard scoring algorithm, it requires additional calculation efforts and yields only marginal improvements in performance.

Category III chronic prostatitis/chronic pelvic pain syndrome: insights from the National Institutes of Health Chronic Prostatitis Collaborative Research Network studies

Chronic prostatitis/chronic pelvic pain syndrome remains an enigmatic medical condition. Creation of the National Institutes of Health-funded Chronic Prostatitis Collaborative Research Network (CPCRN) has stimulated a renewed interest in research on and clinical aspects of chronic prostatitis/chronic pelvic pain syndrome. Landmark publications of the CPCRN document a decade of progress. Insights from these CPCRN studies have improved our management of chronic prostatitis/chronic pelvic pain syndrome and offer hope for continued progress.

Alfuzosin and symptoms of chronic prostatitis-chronic pelvic pain syndrome

BACKGROUND

In men with chronic prostatitis-chronic pelvic pain syndrome, treatment with alpha-adrenergic receptor blockers early in the course of the disorder has been reported to be effective in some, but not all, relatively small randomized trials.

METHODS

We conducted a multicenter, randomized, double-blind, placebo-controlled trial to evaluate the efficacy of alfuzosin, an alpha-adrenergic receptor blocker, in reducing symptoms in men with chronic prostatitis-chronic pelvic pain syndrome. Participation in the study required diagnosis of the condition within the preceding 2 years and no previous treatment with an alpha-adrenergic receptor blocker. Men were randomly assigned to treatment for 12 weeks with either 10 mg of alfuzosin per day or placebo. The primary outcome was a reduction of at least 4 points (from baseline to 12 weeks) in the score on the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) (range, 0 to 43; higher scores indicate more severe symptoms). A 4-point decrease is the minimal clinically significant difference in the score.

RESULTS

A total of 272 eligible participants underwent randomization, and in both study groups, 49.3% of participants had a decrease of at least 4 points in their total NIH-CPSI score (rate difference associated with alfuzosin, 0.1%; 95% confidence interval, -11.2 to 11.0; P=0.99). In addition, a global response assessment showed similar response rates at 12 weeks: 33.6% in the placebo group and 34.8% in the alfuzosin group (P=0.90). The rates of adverse events in the two groups were also similar.

CONCLUSIONS

Our findings do not support the use of alfuzosin to reduce the symptoms of chronic prostatitis-chronic pelvic pain syndrome in men who have not received prior treatment with an alpha-blocker. (ClinicalTrials.gov number, NCT00103402.)

Use of androgen deprivation therapy for metastatic prostate cancer in older men

OBJECTIVE

To assess factors associated with early or delayed androgen deprivation therapy (ADT) among men diagnosed with metastatic prostate cancer, and to assess the relationship between ADT and overall survival, as there is uncertainty about the ideal timing for initiating ADT in men with metastatic prostate cancer.

PATIENTS AND METHODS

We studied a population-based cohort of American men aged >or=66 years diagnosed with metastatic prostate cancer during 1992-2002 and followed to 2003. We assessed the receipt of ADT early (4 months), or not at all, using multinomial logistic regression to identify factors associated with treatment, and Cox proportional-hazard models to assess whether treatment was associated with survival.

RESULTS

Overall, 69.5% of men received early ADT and 7.3% delayed. Adjusted rates of early ADT were lower for black than white men (58.3% vs 71.0%), and of delayed ADT were higher for black than white men (12.7% vs 6.2%). Receipt of ADT was associated with improved survival (adjusted hazard ratio 0.69, 95% confidence interval 0.66-0.73). The benefit of early treatment did not differ from delayed treatment (P = 0.58).

CONCLUSIONS

A large minority of men with metastatic prostate cancer, particularly black men, receive delayed or no ADT. Early or delayed ADT was associated with similarly prolonged survival. After controlling for patient and tumour characteristics, survival did not differ by race, and receipt of ADT did not contribute to racial differences in survival.

Excessive antibiotic use in men with prostatitis

BACKGROUND

Prostatitis accounts for 2 million outpatient visits annually. The majority of prostatitis cases fit the definition of chronic pelvic pain syndrome, for which routine antibiotic use is not indicated.

METHODS

Inpatient, outpatient, and pharmacy datasets from the Veterans Health Administration were used to quantify the magnitude of antibiotic use attributable to chronic pelvic pain syndrome. Specifically, men with a diagnosis of infectious/acute prostatitis or a urinary tract infection were excluded, and the remaining men with a diagnosis of prostatitis were defined as having chronic pelvic pain syndrome.

RESULTS

The annual prevalence of chronic pelvic pain syndrome was 0.5%. Prescriptions for fluoroquinolone antibiotics were filled in 49% of men with a diagnosis of chronic pelvic pain syndrome compared with 5% in men without chronic pelvic pain syndrome. Men with chronic pelvic pain syndrome were more than 7 times more likely to receive a fluoroquinolone prescription independently of age, race/ethnicity, and comorbid conditions. Increased use of other antibiotics also was observed. High use was similar in men with either infectious/acute prostatitis or chronic pelvic pain syndrome.

CONCLUSION

Despite evidence that antibiotics are not effective in the majority of men with chronic pelvic pain syndrome, they were prescribed in 69% of men with this diagnosis. Some increased use is probably due to uncontrolled confounding by comorbid conditions or inaccurate diagnostic coding. However, a 7-fold higher rate of fluoroquinolone usage suggests that strategies to reduce unnecessary antibiotic use in men with prostatitis are warranted.

The association of abuse and symptoms suggestive of chronic prostatitis/chronic pelvic pain syndrome: results from the Boston Area Community Health survey

OBJECTIVE

To determine the effect of reported sexual, physical, or emotional abuse on the symptoms suggestive of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and to determine the effect of race/ethnicity on these patterns.

METHODS

The Boston Area Community Health (BACH) survey used a multi-stage stratified cluster sample to randomly sample 5,506 adults aged 30-79 from the city of Boston. BACH recruited 2,301 men (700 Black, 766 Hispanic, and 835 White). Interviewers administered questions approximating the National Institutes of Health chronic prostatitis symptom index (CPSI), and symptoms suggestive of CP/CPPS were measured by the definition of perineal and/or ejaculatory pain and CPSI pain score of 4+. Questions about previous abuse were obtained from a validated self-administered questionnaire during the home visit. Logistic regression was used to determine the effect of abuse on the likelihood of a man having symptoms suggestive of CP/CPPS.

RESULTS

The prevalence of symptoms suggestive of CP/CPPS was 6.5%. Men who reported having experienced sexual, physical, or emotional abuse had increased odds (1.7-3.3) for symptoms suggestive of CP/CPPS. Previous abuse increased both the pain and urinary scores from the CPSI.

CONCLUSION

Symptoms suggestive of CP/CPPS are not uncommon in a community-based population of men. For men presenting with symptoms suggestive of CP/CPPS, clinicians may wish to consider screening for abuse.

Psychosocial variables affect the quality of life of men diagnosed with chronic prostatitis/chronic pelvic pain syndrome

OBJECTIVE

To examine interactions between demographic, pain, urinary, psychological and environmental predictors of quality of life (QOL) in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

PATIENTS AND METHODS

In all, 253 men previously enrolled in the National Institutes of Health Chronic Prostatitis Cohort study in North American tertiary-care clinical centres (six in the USA and one in Canada) self-reported with validated instruments, including the QOL subscales of the Short Form-12 (physical, SF12-PCS; and mental, SF12-MCS), demographics, urinary symptoms, depression, current pain, pain coping, 'catastrophizing' (catastrophic thinking about pain), pain control, social support and solicitous responses from a partner. Data were collected through a one-time survey. Covariates determined to be significant were entered into a multivariable regression model predicting SF12-PCS and SF12-MCS.

RESULTS

Adjusting for covariates, regression models showed that poorer SF12-PCS scores were predicted by worse urinary function (P < 0.001) and increased use of pain-contingent resting as a coping strategy (P = 0.026). Further, poorer SF12-MCS scores were predicted by greater pain catastrophizing (P = 0.002) and lower perceptions of social support (P< 0.001). In separate follow-up analyses, helplessness was the significant catastrophizing subscale (P < 0.001), while support from family and friends were the significant social support subscales (P = 0.002 and <0.001).

CONCLUSIONS

These data suggest that specific coping and environmental factors (i.e. catastrophizing, pain-contingent resting, social support) are significant in understanding how patients with CP/CPPS adjust. These data can be used to develop specific cognitive-behavioural programmes for men with CP/CPPS who are refractory to standard medical therapy.

Prostatitis

PURPOSE

We quantified the burden of prostatitis in the United States by identifying trends in the use of health care resources and estimating the economic impact of the disease.

MATERIALS AND METHODS

The analytical methods used to generate these results were described previously.

RESULTS

The rate of national inpatient hospitalizations for a diagnosis of prostatitis decreased by 21% between 1994 and 2000. Hospitalization rates were 2 to 2.5 times higher for Medicare beneficiaries with a 42% decrease between 1992 and 2001. Combined physician outpatient and hospital outpatient visits revealed an age adjusted, annualized visit rate for prostatitis of 1,798/100,000 population. More than 6% of visits with a primary diagnosis of prostatitis had a concomitant diagnosis of benign prostatic hyperplasia. The most common medications associated with any visits for prostatitis were quinolones (annualized rate 319/100,000 population) and the rate remained about the same even after visits for infectious prostatitis were removed from the data. The cost of prostatitis was about $84 million annually, exclusive of pharmaceutical spending. Of 897 privately insured men with a medical claim for prostatitis in 2002, 14% missed some work because of the condition.

CONCLUSIONS

Overall spending in the United States for the diagnosis and management of prostatitis, exclusive of pharmaceutical spending, totaled $84 million in 2000 and it appears to be increasing with time. Given the extensive gaps in our understanding of the diagnosis of and treatment for prostatitis, many of these expenditures may represent a waste of resources.

Catastrophizing and Pain-Contingent Rest Predict Patient Adjustment in Men With Chronic Prostatitis/Chronic Pelvic Pain Syndrome

Cognitive/behavioral and environmental variables are significant predictors of patient adjustment in chronic pain. Using a biopsychosocial template and selecting several pain-relevant constructs from physical, cognitive/behavioral, and environmental predictors, outcomes of pain and disability in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) were explored. Men (n = 253) from a North American multi-institutional NIH-funded Chronic Prostatitis Cohort Study in 6 US and 1 Canadian centers participated in a survey examining pain and disability. Measures included demographics, urinary symptoms, depression, pain, disability, catastrophizing, control over pain, pain-contingent rest, social support, and solicitous responses from a significant other. Regressions showed that urinary symptoms (beta = .20), depression (beta = .24), and helplessness catastrophizing (beta = .29) predicted overall pain. Further, affective pain was predicted by depression (beta = .39) and helplessness catastrophizing (beta = .44), whereas sensory pain was predicted by urinary symptoms (beta = .25) and helplessness catastrophizing (beta = .37). With regard to disability, urinary symptoms (beta = .17), pain (beta = .21), and pain-contingent rest (beta = .33) were the predictors. These results suggest cognitive/behavioral variables (ie, catastrophizing, pain-contingent rest) may have significant impact on patient adjustment in CP/CPPS. Findings support the need for greater research of such pain-related variables in CP/CPPS.

PERSPECTIVE

This article explores predictors of patient adjustment in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Cognitive/behavioral variables of catastrophizing and pain-contingent rest respectively predicted greater pain and disability. Catastrophic helplessness was a prominent pain predictor. These findings inform clinicians and researchers on several new variables in CP/CPPS outcomes and suggest future research.

Responsiveness of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI)

OBJECTIVES

The NIH-Chronic Prostatitis Symptom Index (NIH-CPSI) was developed to assess symptoms and quality of life in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). We assessed the responsiveness of the NIH-CPSI to change over time and defined thresholds for changes perceptible to patients.

METHODS

We studied 174 men with CP/CPPS who participated in a placebo-controlled randomized clinical trial. Changes from baseline to six weeks in the NIH-CPSI total score and pain, urinary, and quality of life subscores were compared to a global response assessment (GRA). Effect sizes and Guyatt statistics were calculated to evaluate responsiveness; 95% confidence intervals were produced using bootstrapping.

RESULTS

All scores decreased over time with the largest decrease in subjects who reported on the GRA that they were markedly improved. The NIH-CPSI total, pain, and quality of life scores were highly responsive in the improved groups; the urinary score showed minimal responsiveness. There was no evidence of responsiveness among those subjects who worsened on the trial. ROC curves identified a 6-point decline in the NIH-CPSI total score as the optimal threshold to predict treatment response.

CONCLUSIONS

The NIH-CPSI total score and pain and quality of life subscores are responsive to change over time.

The impact of a suspicious prostate biopsy on patients' psychological, socio-behavioral, and medical care outcomes

OBJECTIVE

To evaluate the psychological, socio-behavioral, and medical implications of apparently false-positive prostate cancer screening results.

METHODS

One hundred and twenty-one men with a benign prostate biopsy performed in response to a suspicious screening test (biopsy group) and 164 men with a normal prostate-specific antigen (PSA) test result (normal PSA group) responded to a questionnaire 6 weeks, 6 and 12 months after their biopsy or PSA test.

RESULTS

The mean (+/-SD) age of respondents was 61+/-9 years (range, 41 to 88 years). One year later, 26% (32/121) of men in the biopsy group reported having worried "a lot" or "some of the time" that they may develop prostate cancer, compared with 6% (10/164) in the normal PSA group (P<.001). Forty-six percent of the biopsy group reported thinking their wife or significant other was concerned about prostate cancer, versus 14% in the normal PSA group (P<.001). Medical record review showed that biopsied men were more likely than those in the normal PSA group to have had at least 1 follow-up PSA test over the year (73% vs 42%, P<.001), more likely to have had another biopsy (15% vs 1%, P<.001), and more likely to have visited a urologist (71% vs 13%, P<.001).

CONCLUSION

One year later, men who underwent prostate biopsy more often reported worrying about prostate cancer. In addition, there were related psychological, socio-behavioral, and medical care implications. These hidden tolls associated with screening should be considered in the discussion about the benefits and risks of prostate cancer screening.

Validity of primary care patient self-report of abnormal (but not cancer) prostate biopsy results

PURPOSE

We assessed the validity of patient self-report of abnormal (but not cancer) prostate biopsy results, ie, atypical cells or prostatic intraepithelial neoplasia.

MATERIALS AND METHODS

We compared survey responses and pathology records for 156 men from a multicenter, prospective cohort study, which was designed to evaluate the impact of a suspicious prostate cancer screening test followed by benign prostate biopsy.

RESULTS

Of the 156 subjects 45 (29%) reported having had atypical cells or prostatic intraepithelial neoplasia and 38 (24%) had a pathology report with atypia or prostate intraepithelial neoplasia. The sensitivity of the self-report was 87%, specificity was 90%, positive predictive value was 73% and negative predictive value was 95%. The kappa statistic was 0.7.

CONCLUSIONS

Men in this study reported this complex result accurately. However, it was concerning that 5 men (13%) appeared unaware of an abnormal prostate biopsy result, especially given the substantial residual risk of prostate cancer conferred by this result.

A prospective study of symptoms and quality of life in men with chronic prostatitis/chronic pelvic pain syndrome: the National Institutes of Health Chronic Prostatitis Cohort study

PURPOSE

We present the results of 2 years of symptom and quality of life followup of men with CP/CPPS enrolled in the CPC.

MATERIALS AND METHODS

We followed 445 subjects from 6 clinical centers across North America for 2 years with outcome measures that included the NIH-CPSI, quality of life, and GRA. All subjects were treated according to usual care practices at each clinical site.

RESULTS

Of the 445 subjects 293 had complete data at 2 years. Withdrawals were younger, had been diagnosed more recently and had higher baseline symptoms. Among the 293 men the mean improvement at 2 years was 5 points on the 43-point NIH-CPSI total score. Most of the observed improvement occurred in the first 3 months of followup. Among all 445 subjects, retaining withdrawals in the denominator, 31% considered themselves moderately or markedly improved at 2 years. Although group mean symptom scores were stable and improved slightly over time, some individual subjects reported large fluctuations. No baseline demographic or clinical factors significantly predicted changes in symptom scores over time.

CONCLUSIONS

CP/CPPS is a chronic disease characterized by substantial variation in symptoms within and among subjects. There is no evidence that the disorder worsens significantly during 2 years of followup, and for about a third of men with long-standing symptoms there may be moderate to marked improvement during this period.

Managing patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia

Many men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia can be managed safely and effectively by primary care providers. After a basic evaluation to exclude other diseases that may cause lower urinary tract symptoms, quantifying the degree of symptoms and bother, and perhaps making an assessment of prostate size, the primary care provider can determine which men require immediate evaluation by a urologist and which men may choose among various treatment options, including watchful waiting and various single agent or combination medication strategies. Recent information about risk factors for disease progression has also helped to inform patient decisions on which treatment option is best for the individual patient. The purpose of this review is to provide primary care providers with an approach to the management of men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia.

DEVELOPMENT OF A MULTIREGIONAL UNITED STATES SPANISH VERSION OF THE INTERNATIONAL PROSTATE SYMPTOM SCORE AND THE BENIGN PROSTATIC HYPERPLASIA IMPACT INDEX

PURPOSE

The International Prostate Symptom Score (I-PSS) and Benign Prostatic Hyperplasia Impact Index (BII) have gained widespread use in clinical practice and clinical trials. Although Spanish translations of the I-PSS are available, to our knowledge none was developed for the Spanish speaking population in the United States using a methodology to ensure appropriateness for the diverse United States Spanish speaking population. An existing translation intended for another Spanish speaking country, such as Mexico, or a translation developed without input from each language group may not be understood by those who immigrated from other Latin American regions. Hence, the development of a Spanish translation for the United States should involve input from translators from each region of Latin America.

MATERIALS AND METHODS

We reviewed and modified an existing United States Spanish translation of I-PSS using a multiregional reconciliation panel comprised of representatives from each of the major Spanish language groups in the United States. For BII full translation methodology was used to develop a translation for the United States, including 2 forward translations using translators from more than 1 region, a multiregional reconciliation panel meeting, a back translation evaluation, cognitive debriefing interviews with representatives from each language group, developer review, a final evaluation for consistency and proofreading.

RESULTS

The revised I-PSS better reflects common Spanish wording in the United States, while the BII translation was confirmed to be comprehended by Spanish speakers in the United States originating from multiple regions of Latin America.

CONCLUSIONS

United States Spanish translations of patient reported outcome measures should consider the diversity of the growing Spanish speaking population in the United States to ensure comprehension across the broad population originating from the multiple regions of Latin America.

A case-control study of risk factors in men with chronic pelvic pain syndrome

OBJECTIVE

To compare the demographic, behavioural, clinical and medical history characteristics of men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and asymptomatic controls, to identify characteristics that might be associated with this syndrome.

PATIENTS AND METHODS

Self-administered epidemiological questionnaires were completed by 463 men with CP/CPPS and 121 asymptomatic age-matched controls. We compared the prevalence of possible risk factors between men with CP/CPPS and controls, using generalized Mantel-Haenszel tests, and developed multivariate predictive models using logistic regression methods, adjusting for clustering by clinical centre within both methods.

RESULTS

Compared to controls, men with CP/CPPS reported a significantly greater lifetime prevalence of nonspecific urethritis (12% vs 4%, P = 0.008), cardiovascular disease (11% vs 2%, P = 0.004), neurological disease (41% vs 14%, P < 0.001), psychiatric conditions (29% vs 11%, P < 0.001), and haematopoietic, lymphatic or infectious disease (41% vs 20%, P < 0.001).

CONCLUSION

A wide range of self-reported medical conditions was associated with CP/CPPS. Further studies are necessary to determine whether they play a role in the pathogenesis of CP/CPPS.

Psychological effects of a suspicious prostate cancer screening test followed by a benign biopsy result

PURPOSE

To evaluate the psychological implications of an apparently false-positive screening result for prostate cancer.

METHODS

The sample comprised 167 men with a benign biopsy result in response to a suspicious screening test result (biopsy group) and 233 men with a normal prostate-specific antigen (PSA) test result (control group). The men responded to a questionnaire within about 6 weeks of their biopsy or PSA results. They were asked about demographic characteristics, medical history, psychological effects, biopsy experience, and prostate cancer knowledge.

RESULTS

The survey response rate was 85% (400/471). The mean (+/- SD) age of respondents was 60 +/- 9 years (range, 40 to 88 years); 88% (n = 350) were white. Forty-nine percent (81/167) of men in the biopsy group reported having thought about prostate cancer either "a lot" or "some of the time", compared with 18% (42/230) in the control group (P < 0.001). In addition, 40% (67/167) in the biopsy group reported having worried "a lot" or "some of the time" that they may develop prostate cancer, compared with 8% (18/231) in the control group (P < 0.001).

CONCLUSION

Men who underwent prostate biopsy more often reported having thought and worried about prostate cancer, despite having received a benign result. This underrecognized human cost of screening should be considered in the debate about the benefits and harms of prostate cancer screening.

Ciprofloxacin or tamsulosin in men with chronic prostatitis/chronic pelvic pain syndrome: a randomized, double-blind trial

BACKGROUND

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in men is principally defined by pain in the pelvic region lasting more than 3 months. No cause of the disease has been established, and therapies are empirical and mostly untested. Antimicrobial agents and alpha-adrenergic receptor blockers are frequently used.

OBJECTIVE

To determine whether 6-week therapy with ciprofloxacin or tamsulosin is more effective than placebo at improving symptoms in men with refractory, long-standing CP/CPPS.

DESIGN

Randomized, double-blind trial with a 2 x 2 factorial design comparing 6 weeks of therapy with ciprofloxacin, tamsulosin, both drugs, or placebo.

SETTING

Urology outpatient clinics at 10 tertiary care medical centers in North America.

PATIENTS

Patients were identified from referral-based practices of urologists. One hundred ninety-six men with a National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score of at least 15 and a mean of 6.2 years of symptoms were enrolled. Patients had received substantial previous treatment.

MEASUREMENTS

The authors evaluated NIH-CPSI total score and subscores, patient-reported global response assessment, a generic measure of quality of life, and adverse events.

INTERVENTIONS

Ciprofloxacin, 500 mg twice daily; tamsulosin, 0.4 mg once daily; a combination of the 2 drugs; or placebo.

RESULTS

The NIH-CPSI total score decreased modestly in all treatment groups. No statistically significant difference in the primary outcome was seen for ciprofloxacin versus no ciprofloxacin (P = 0.15) or tamsulosin versus no tamsulosin (P > 0.2). Treatments also did not differ significantly for any of the secondary outcomes.

LIMITATIONS

Treatment lasting longer than 6 weeks was not tested. Patients who had received less pretreatment may have responded differently.

CONCLUSION

Ciprofloxacin and tamsulosin did not substantially reduce symptoms in men with long-standing CP/CPPS who had at least moderate symptoms.

Health-Related Quality of Life, Satisfaction, and Economic Outcome Measures in Studies of Prostate Cancer Screening and Treatment, 1990-2000

Prostate cancer outcomes research incorporates a broad spectrum of endpoints, from clinical or intermediate endpoints, such as tumor shrinkage or patient compliance, to final endpoints, such as survival or disease-free survival. Three types of nontraditional endpoints that are of growing interest-health-related quality of life (QOL), satisfaction with care, and economic cost impact-hold the promise of improving our ability to understand the full burden of prostate cancer screening and treatment. In this article we review the last decade's published literature regarding the health-related QOL, satisfaction, and economic outcomes of prostate cancer screening and treatment to determine the "state of the science" of outcomes measurement. The focus is the enumeration of the types of outcome measurement used in the studies not the determination of the results of the studies. Studies were identified by searching Medline (1990-2000). Articles were included if they presented original data on any patient-centered outcome (including costs or survival alone) for men screened and treated for prostate cancer. Review papers were excluded unless they were quantitative syntheses of the results of other primary studies. Economic and decision analytic papers were included if they presented information on outcomes of real or hypothetical patient cohorts. Each retrieved article was reviewed by one of the authors. Included papers were assigned one primary, mutually exclusive study design. For the "primary data" studies, information was abstracted on care setting, dates of the study, sample size, racial distribution, age, tumor differentiation, tumor stage, survival, statistical power, and types of outcomes measures (QOL-generic, QOL-cancer specific, QOL-prostate cancer specific, satisfaction, costs, utilities, and other). For the "economic and decision analytic" papers, information was abstracted on stage of disease, age range, outcomes, costs, and whether utilities were measured. Of the 198 included papers, there were 161 primary data papers categorized as follows: randomized trial (n = 28), nonrandomized trial (n = 13), prospective or retrospective cohort study (n = 55), case-control study (n = 0), cross-sectional study (n = 63), and meta-analysis (n = 2). The remaining 37 papers were economic and decision analytic papers. Among the 149 primary data papers that contained patient outcome data, there were 42 standard instruments used, accounting for 44% (179 of 410) of the measures overall. Almost three-quarters (71%) of papers included one, two, or three outcomes measures of all types (standard and nonstandard); three papers included seven outcomes measures, and one paper included nine. Over the 11-year time period, there was a nonstatistically significant trend toward more frequent use of standardized QOL instruments and a statistically significant trend toward increased reporting of race (P = .003). Standardization of measurement of health-related QOL, satisfaction with care, and economic cost effect among men screened and treated for prostate cancer is needed. A core set of similar questions, both generic and disease-specific, should ideally be asked in every study, although investigators should be encouraged to include additional question sets as appropriate to individual studies to get a more complete picture of how patients screened and treated for this condition are doing over time.

The National Institutes of Health chronic prostatitis symptom index: development and validation of a new outcome measure. Chronic Prostatitis Collaborative Research Network

PURPOSE

Chronic abacterial prostatitis is a syndrome characterized by pelvic pain and voiding symptoms, which is poorly defined, poorly understood, poorly treated and bothersome. Research and clinical efforts to help men with this syndrome have been hampered by the absence of a widely accepted, reliable and valid instrument to measure symptoms and quality of life impact. We developed a psychometrically valid index of symptoms and quality of life impact for men with chronic prostatitis.

MATERIALS AND METHODS

We conducted a structured literature review of previous work to provide a foundation for the new instrument. We then conducted a series of focus groups comprising chronic prostatitis patients at 4 centers in North America, in which we identified the most important symptoms and effects of the condition. The results were used to create an initial draft of 55 questions that were used for formal cognitive testing on chronic prostatitis patients at the same centers. After expert panel review formal validation testing of a revised 21-item draft was performed in a diverse group of chronic prostatitis patients and 2 control groups of benign prostatic hyperplasia patients and healthy men. Based on this validation study, the index was finalized.

RESULTS

Analysis yielded an index of 9 items that address 3 different aspects of the chronic prostatitis experience. The primary component was pain, which we captured in 4 items focused on location, severity and frequency. Urinary function, another important component of symptoms, was captured in 2 items (1 irritative and 1 obstructive). Quality of life impact was captured with 3 items about the effect of symptoms on daily activities. The 9 items had high test-retest reliability (r = 0.83 to 0.93) and internal consistency (alpha = 0.86 to 0.91). All but the urinary items discriminated well between men with and without chronic prostatitis.

CONCLUSIONS

The National Institutes of Health chronic prostatitis symptom index provides a valid outcome measure for men with chronic prostatitis. The index is psychometrically robust, easily self-administered and highly discriminative. It was formally developed and psychometrically validated, and may be useful in clinical practice as well as research protocols.
