The Economic Burden of Nocturia on the U.S. Health Care System and Society: A National Health and Nutrition Examination Survey Analysis.

BACKGROUND: Nocturia, characterized as waking during the main sleep period to urinate, is a common condition. Persistent nocturia results in sleep fragmentation with deleterious effects on health and well-being. Yet, there are limited data on the economic burden of nocturia in the United States. OBJECTIVE: To assess the association of nocturia with health care resource utilization (HRU), work productivity, and self-rated health while estimating the societal costs of nocturia in the United States in 2017. METHODS: A retrospective cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey (NHANES; 2005-2006 to 2013-2014). Adults aged ≥ 18 years (excluding pregnant women) were stratified into individuals with nocturia (≥ 2 voids/night) and individuals without nocturia (< 2 voids/night), based on the threshold for clinically significant nocturia. Outcomes were self-reported and included HRU (hospitalizations, outpatient visits); work productivity (weekly hours worked, employment); and current health status. Multivariable regression analyses adjusting for age, race, sex, body mass index, insurance status, education level, alcohol use, smoking status, and self-reported comorbid conditions were used to compare the 2 cohorts, overall and stratified by age group (20-44 years, 45-64 years, and 65+ years) to distinguish the effects on different age groups including the Medicare-aged population. Excess direct health care costs and indirect productivity costs associated with nocturia in the United States were then calculated using a prevalence-based approach and available literature (i.e., nocturia prevalence estimates, aggregated unit costs by HRU type, and average hourly earnings in the United States). RESULTS: 22,300 individuals were identified, and 24% had nocturia (≥ 2 voids/night). Median age was 55.2 and 43.2 years among individuals with and without nocturia, respectively, and the proportion of males was 43.3% and 51.3%, respectively. Individuals with nocturia had significantly more HRU, including hospitalizations and outpatient visits, worked significantly fewer hours weekly, and were significantly less likely to be employed when compared with those without nocturia. They were also significantly less likely to report being in very good/excellent health. These comparisons remained statistically significant across age groups. Total excess direct health care costs were $62.9 billion (hospitalization: $47.6 billion; outpatient: $15.3 billion). Total excess indirect productivity costs were $151.7 billion. Altogether, costs were estimated at $214.5 billion, equivalent to $3,491 per individual with nocturia. Individuals aged 20-44 years incurred 23.5% of total excess costs, while those aged 45-64 and 65+ years incurred 48.2% and 28.3%, respectively. Sensitivity analyses based on lower prevalence estimates resulted in costs of $94.0 billion, while those based on higher prevalence estimates reached up to $231.1 billion. CONCLUSIONS: Nocturia is associated with a substantial economic burden in the United States even when evaluated based on lower prevalence estimates. This study underscores the importance of timely diagnosis and management of nocturia patients to alleviate health-related and economic consequences to patients and society.

Current guidelines and treatment paradigms for nocturnal polyuria: A "NEW" disease state for US physicians, patients and payers.

Nocturia is one of the most bothersome symptoms encountered in urology, and its prevalence rises with age. Causes include both urological and non-urological aetiologies, often in combination. The effects of nocturia on a patient's quality of life can be detrimental. The initial approach to managing this condition includes appropriately classifying nocturia based on the results of a 24-hour bladder diary. Broadly, the categories under which nocturia can be classified include: low nocturnal or global bladder capacity, nocturnal polyuria, global polyuria and mixed.Based on the type of nocturia and possible underlying causes, clinicians can appropriately discuss with patients the treatment plans that may include a combination of behavioural, pharmacologic, and invasive therapy. The available literature on the management of nocturia was reviewed. Findings were incorporated into a practice-based approach for its workup and treatment.

Economic Burden of Illness in Adult Patients with Nocturia.

BACKGROUND: Nocturia is considered to be a very bothersome lower urinary tract disorder. Yet, to date, the economic burden attributable to this poor health condition remains less well known. OBJECTIVE: To compare differences in health care resource utilization (HCRU), health care costs, and work productivity in adult patients with differing frequencies of nocturia episodes (i.e., < 2 vs. ≥ 2 nocturia episodes per night). METHODS: Adult patients with nocturia enrolled in an integrated proprietary database were recruited to complete a survey on their demographics, nocturia characteristics, and work productivity. Using patients' survey data and health care claims from the previous 6 months, those with < 2 (n = 197; 21.9%) versus ≥ 2 (n = 702; 78.1%) nocturia episodes per night were compared for differences in HCRU, health care costs, and work productivity after adjusting for potential confounders. HCRU was reported as the mean number per patient per month (PPPM) for outpatient visits (all types), physician office visits, and prescriptions filled and the proportion of patients with ≥1 hospitalization or emergency department visit in the previous 6 months. Health care costs were reported as mean PPPM. Work productivity was assessed via patient survey and reported as a mean percentage for absenteeism, presenteeism, overall work impairment, and activity impairment during the past week. RESULTS: 899 adult patients (mean age = 71.4 years; 57.2% men) were enrolled and analyzed. Compared with patients with <2 nocturia episodes per night, patients with ≥ 2 nocturia episodes had more outpatient health care visits (unadjusted mean visits PPPM: 2.1 vs. 1.6; P < 0.001; adjusted mean visits PPPM: 2.1 vs. 1.6; P = 0.017), office visits (unadjusted and adjusted mean visits PPPM: 0.9 vs. 0.7; P < 0.001), and prescriptions filled (unadjusted mean prescription fills PPPM: 3.1 vs. 2.1; P < 0.001; adjusted mean prescription fills PPPM: 3.2 vs. 2.2; P = 0.027). Patients with ≥ 2 nocturia episodes per night also displayed significantly higher outpatient health care costs (unadjusted mean PPPM costs: $676 vs. $516; P = 0.028; adjusted mean PPPM costs: $678 vs. $506; P = 0.017). In terms of work productivity impairment, patients with ≥ 2 nocturia episodes per night experienced higher rates of unadjusted (20% vs. 10%; P = 0.002) and adjusted presenteeism (20% vs. 10%; P = 0.004) and unadjusted (20% vs. 10%; P = 0.002) and adjusted overall work impairment (20% vs. 10%; P = 0.001). CONCLUSIONS: Study findings demonstrate that nocturia was associated with higher outpatient encounters and related costs in the presence of a greater occurrence of nocturic episodes.

Annual direct and indirect costs attributable to nocturia in Germany, Sweden, and the UK.

OBJECTIVE: Our aim was to estimate the prevalence-based cost of illness imposed by nocturia (≥2 nocturnal voids per night) in Germany, Sweden, and the UK in an average year. METHODS: Information obtained from a systematic review of published literature and clinicians was used to construct an algorithm depicting the management of nocturia in these three countries. This enabled an estimation of (1) annual levels of healthcare resource use, (2) annual cost of healthcare resource use, and (3) annual societal cost arising from presenteeism and absenteeism attributable to nocturia in each country. RESULTS: In an average year, there are an estimated 12.5, 1.2, and 8.6 million patients ≥20 years of age with nocturia in Germany, Sweden, and the UK, respectively. In an average year in each country, respectively, these patients were estimated to have 13.8, 1.4, and 10.0 million visits to a family practitioner or specialist, ~91,000, 9000, and 63,000 hospital admissions attributable to nocturia and 216,000, 19,000, and 130,000 subjects were estimated to incur a fracture resulting from nocturia. The annual direct cost of healthcare resource use attributable to managing nocturia was estimated to be approximately €2.32 billion in Germany, 5.11 billion kr (€0.54 billion) in Sweden, and £1.35 billion (€1.77 billion) in the UK. The annual indirect societal cost arising from both presenteeism and absenteeism was estimated to be approximately €20.76 billion in Germany and 19.65 billion kr (€2.10 billion) in Sweden. In addition, in the UK, the annual indirect cost due to absenteeism was an estimated £4.32 billion (€5.64 billion). CONCLUSIONS: Nocturia appears to impose a substantial socioeconomic burden in all three countries. Clinical and economic benefits could accrue from an increased awareness of the impact that nocturia imposes on patients, health services, and society as a whole.

The economic impact of nocturia.

Sleep disturbances associated with nocturia cause direct, indirect, and intangible costs. Direct costs are primarily associated with injuries from falling. Indirect costs are associated with loss of work productivity. Intangible costs include emotional distress, behavioral modifications, feelings of loss of control, poor mood, and cancellation of planned activities. A study that compared the number of falls for patients with varying numbers of voids per night demonstrated that the incremental risk (population attributable risk [PAR]) of falling as a result of nocturia (≥ 2 voids compared with ≤ 1 void) was 16.2%. Using the 16.2% PAR, the annual direct cost of nocturia in the USA was estimated at $1.5 billion. An analysis in the EU-15 countries estimated the total annual cost of hospitalizations for hip fracture due to severe nocturia to be approximately € 1 billion. Studies have shown that periods of sick leave are significantly greater in both men and women who have more nocturnal voids, with an estimated annual indirect cost of nocturia of $61 billion in the USA. A similar European analysis showed an estimated annual cost of lost work productivity due to nocturia of € 29 billion in the EU-15. The intangible personal costs of nocturia are related to diminished quality of life and overall health status. High-quality articles on the cost of illness associated with nocturia, as well as cost-benefit analyses of nocturia treatment, are generally lacking.

Nocturia: new directions.

The Nocturia Think Tank (TT) met during the 2010 meeting of the International Consultation on Incontinence-Research Society to discuss present knowledge and future directions in care and research of this prominent component of the spectrum of lower urinary tract symptoms. Questions raised included whether nocturia should be re-defined as a function of its bother, effects on quality of life, and economic impact upon society. At issue is the need to delineate the determinants of successful nocturia management. The multifactorial nature of nocturia requires that progress in its treatment will be dependent upon the cooperative investigation on the part of urologists, urogynecologists, geriatricians, epidemiologists, medical economists and pharma. Areas for future avenues of research were outlined at the conclusion of the meeting.
