Aetna considers the use of a bedwetting alarm medically necessary durable medical equipment for the treatment of primary nocturnal enuresis when all of the following criteria are met:
Aetna considers the use of a bedwetting alarm experimental and investigational when the afore-mentioned criteria are not met.
Aetna considers desmopressin medically necessary for the treatment of primary nocturnal enuresis in children older than 5 years whose bedwetting has not responded to non-pharmacologic therapies (e.g., bladder-training exercises, fluid and food intake advice, enuresis alarm treatment; or refused or are unlikely to adhere to enuresis alarm treatment).
Aetna considers the following interventions for the treatment of nocturnal enuresis experimental and investigational because their effectiveness for this indication have not been established.
Note: Special training and skilled care or monitoring services to use the enuresis alarm are not generally considered medically necessary.Background
Primary nocturnal enuresis (NE) refers to involuntary loss of urine during sleep in patients who have never achieved a sustained period of dryness. Secondary NE is enuresis that develops after a patient has achieved a sustained period of bladder control. More than 5 % of 7-year old children and 0.5 % of adults experience primary nocturnal enuresis. Nocturnal enuresis in children is rarely caused by psychological factors. It is usually the result of a delay in maturation of the somatic mechanisms -- reduction of nocturnal urine production, relaxation of the bladder during sleep, and a normal arousal to a full bladder -- that prevent bedwetting. There is evidence of genetic predisposition to primary nocturnal enuresis.
Primary NE resolves spontaneously in most children over time. Treatment options include pharmacotherapy, the enuretic alarm, and complex regimens such as dry-bed training. Recently, desmopressin acetate (DDAVP) nasal spray has been found to be useful when temporary cessation of symptoms is necessary, such as for enuretic children attending school camps or sleeping over at friends' homes. Treatment of NE with imipramine has fallen into disfavor because of high relapse rate and risk of fatal over-dosing. By far, the most successful treatment is the enuretic alarm; it enjoys the best long-term cure rate and lowest relapse rate of treatment for primary NE. The enuretic alarm is most effective in patients with the highest frequency of NE. Bedwetting alarms provide biofeedback to enhance bladder sensation and overcome sleep arousal difficulties. However, behavioral modification techniques such as enuretic alarm require strong commitment and are rarely successful in patients less than 7 years of age.
Naitoh et al (2005) noted that desmopressin and imipramine combined with an alarm was no more effective than alarm monotherapy. As for alarm monotherapy, other therapeutic modalities should be considered if it has not proved effective after 3 months. In such a situation, combination therapy may be effective as a second choice.
Kang et al (2007) evaluated the effect of extracorporeal magnetic innervation (ExMI) therapy in children with refractory monosymptomatic nocturnal enuresis (MNE). A total of 55 children (21 girls and 34 boys, median age of 8.0 years, range of 5 to 13) who wetted the bed more than twice per week because of MNE that was refractory to treatment with desmopressin, anti-cholinergics, and enuretic alarm were assessed prospectively using a voiding diary before and after ExMI, administered once-weekly for at least 4 weeks with a size-adjusted magnetic chair (each session lasted 20 mins). After all sessions of ExMI, the mean frequency of NE decreased significantly to 2.09 +/- 2.47 in all patients (p = 0.04), and the mean functional bladder capacity increased 1.88 times in all patients (p = 0.00). In total, 63.6 % of patients had a NE frequency of less than 50 % after a mean of 6.62 +/- 4.26 ExMI sessions. The authors concluded that reduced functional bladder capacity might be the main pathophysiological cause in children with MNE refractory to established treatment. Extracorporeal magnetic innervation might have an acute inhibitory effect in children with refractory MNE by increasing functional bladder capacity. However, they stated that long-term follow-up data and controlled study with a sham-stimulation group are needed to determine the durability of this new therapy for refractory MNE.
Libonate et al (2008) stated that acupuncture has been used to treat a variety of childhood problems; however, the safety and effectiveness of pediatric acupuncture remains unclear. These researchers reviewed the existing empirical literature relating to the use of acupuncture for medical conditions in children. A systematic search of the literature revealed that acupuncture has been used in the treatment of 5 main conditions in children: (i) pain, (ii) NE, (iii) post-operative nausea and vomiting, (iv) laryngospasm/stridor, and (v) neurological disorders. Despite a number of methodological issues, including limited sample sizes, lack of randomization, and inappropriate control groups, it is concluded that acupuncture represents a promising intervention for a variety of pediatric health conditions. Moreover, the authors concluded that large-scale randomized controlled trials are needed to further address the safety, effectiveness, and acceptability of acupuncture in children.
Reed and colleagues (1994) assessed chiropractic management of primary NE in children in a controlled clinical trial for 10 weeks preceded by and followed by a 2-week non-treatment period. A total of 46 nocturnal enuretic children (31 treatment and 15 control group) from a group of 57 children initially included in the study, participated in the trial. Subjects received high-velocity, short -ever adjustments of the spine consistent with the Palmer Package Techniques; or a sham adjustment using an Activator at a non-tension setting administered to the examiner's underlying contact point. Two 5th-year chiropractic students under the supervision of 2 clinic faculty performed the adjustments. Main outcome measure was frequency of wet nights. The post-treatment mean wet night frequency of 7.6 nights/2 weeks for the treatment group was significantly less than its baseline mean wet night frequency of 9.1 nights/2 weeks (p = 0.05). For the control group, there was practically no change (12.1 to 12.2 nights/2 weeks) in the mean wet night frequency from the baseline to the post-treatment. The mean pre- to post-treatment change in the wet night frequency for the treatment group compared with the control group did not reach statistical significance (p = 0.067). Twenty-five percent of the treatment-group children had 50 % or more reduction in the wet night frequency from baseline to post-treatment while none among the control group had such reduction. The authors concluded that these findings suggested that chiropractic treatment is effective for primary NE. Moreover, they stated that a larger study of longer duration with a 6-month follow-up is needed.
Kreitz and Aker (1994) performed a comprehensive review of the literature concerning the etiology, diagnosis, and the natural history of primary NE. Contemporary treatment options are discussed in light of the documented annual remission rate of this disorder. Articles reviewed were obtained by conducting a computer-aided search of papers indexed in Medline and the Index to Chiropractic Literature from 1989 to 1993. In addition, the Chiropractic Research Abstracts Collection and bibliographies from pertinent articles were manually searched. Primary NE affects some 200,000 children and their families throughout Canada. Twenty percent of children wet the bed at age 5, 10 % at age 10, and only about 1 % at age 15. The documented natural history of the disorder reveals that for those affected, 10 % to 20 % exhibit spontaneous resolution per year. Contemporary treatment options center on 3 factors that play primary roles in the etiology of this condition: (i) functional bladder capacity, (ii) patient conditioning, and (iii) the circadian rhythm of nocturnal secretion of vasopressin. The authors concluded that the success of each therapeutic option must, in part, be attributed to the natural history of enuresis, as well as any educational or placebo aspects of treatment. Conditioning therapy utilizing the urine pad alarm may be the most reasonable initial mode of intervention. Spinal manipulative therapy has been shown to possess an efficacy comparable to the natural history.
van Poecke and Cunliffe (2009) evaluated the effect of a specific type of chiropractic treatment on the wet night frequency of patients between the ages of 3 and 18 years who were treated for primary NE in the chiropractic setting. A total of 33 consecutive patient, dating over a 3-year period, of children 3 to 18 years old who had been treated for primary NE using a form of chiropractic treatment method (NeuroImpulse Protocol) were included. All patient records were analyzed for a baseline wet night frequency and at 3, 6, 9, and 12 months after the commencement of treatment. Data were collected regarding the number of treatment visits over the 12-month period and the presence of constipation and/or positive family history at presentation. Data were analyzed using descriptive statistics, Friedman's test, and Dunn's Multiple Comparison test. Of the 33 patient records analyzed, 22 showed resolution of primary NE during the 12 months after commencement of chiropractic care. The mean number of treatments in the responders group was 2.05 +/- 1.33. Ten responders presented with constipation and a further 8 with a positive family history of primary NE. Resolution of constipation was noted to be essential to the successful response to treatment. A combination of constipation and positive family history at presentation represented a poor prognostic factor. The authors concluded that there was a 66.6 % resolution rate within 1 year in 33 consecutive children and teenagers who experienced primary NE. These findings provided an indication for possible effectiveness of chiropractic treatment in patients with primary NE. The results of this small retrospective study need to be validated by well-designed studies.
The International Children's Continence Society's guideline on the evaluation and treatment of MNE (Neveus et al, 2010) noted that the mainstays of primary therapy are bladder advice, the enuresis alarm and/or desmopressin. Among the recommended second-line therapies are anti-cholinergics and in select cases imipramine. Chiropractic management is not discussed as a therapeutic option for these patients.
A French task force of 6 experts based its work on the guide for literature analysis and recommendations and recommendation grading of the French Haute Autorité de Santé (formalized consensus process methodological guidelines) to evaluate the level of scientific proof (grade of 1 to 4) and the strength of the recommendations (grade A, B, C) of the publications on primary NE. A total of 223 articles from 2003 on were identified, of which only 127 (57 %) had an evaluable level of proof. This evaluation was then reviewed by a 19-member rating group. Several recommendations, poorly defined by the literature, had to be proposed by a professional agreement resulting from a consultation between the members of the task force and those of the rating group. For its final validation, the document was submitted to a reading group of 21 members working in a wide range of specialist areas and practices but all involved in primary NE. The definition of primary NE is very specific: intermittent incontinence during sleep, from the age of 5, with no continuous period of continence longer than 6 months, with no other associated symptom, particularly during the day. Its diagnosis is clinical by the exclusion of all other urinary pathologies. Two factors must be identified during the consultation: (i) nocturnal polyuria promoted by excessive fluid intake, and (ii) inverse secretion of vasopressin, snoring and sleep apnea. It is sensitive to desmopressin; small bladder capacity evaluated according to a voiding diary and the International Children's Continence Society formula. It may be associated with diurnal hyperactivity of the detrusor (30 %). It is resistant to desmopressin. Problems associated with primary NE are: abnormal arousal threshold, attention deficit hyperactivity disorder (ADHD) (10 %), low self-esteem. The psychological component is not very significant. The authors concludedthat primary NE is not psychological in origin. The management of this condition includes: evaluating the intra-familial tolerance and the child's motivation, evaluating the rate, the volume of urine and wet nights using a diurnal and nocturnal diary; education (sufficient fluid intake at the start of the day, decrease in hyper-osmolar intake in the evening, regular and complete urination); specific treatments: desmopressin for polyuric forms (expected success rate of 60 to 70 %), alarms for forms involving small bladder capacity (expected success rate of 60 to 80 %); alternative treatments and/or treatments combined with the preceding ones, for refractory forms: oxybutinin, tricyclic anti-depressants (risk). Results obtained with hypnosis, psychotherapy, acupuncture, homeopathy or chiropractic are not currently validated (insufficient level of proof).
Kalorin and colleagues (2010) noted that sleep disordered breathing caused by tonsillar hypertrophy has been implicated as a cause of primary and secondary NE in children. In a prospective, controlled trial, these investigators studied the pre-operative and post-operative rates of nocturnal and daytime incontinence in a group of children with tonsillar hypertrophy undergoing tonsillectomy compared to a matched control group undergoing surgery unrelated to the airway or urinary tract. A total of 326 toilet trained children 3 to 15 years old were included, with 257 in the tonsillectomy group and 69 in the control group. Severity of tonsillar hypertrophy was graded pre-operatively on a scale of 1 to 4. A voiding questionnaire regarding number of bedwetting and daytime incontinence episodes per week, voids per day, bowel movements per week, secondary or primary enuresis and family history was completed by parents pre-operatively, and at 3 and 6 months post-operatively. Pre-operatively, the respective rates of NE and daytime incontinence were 33 % and 17 % in the tonsillectomy group (p = 0.89), and 35 % and 14 % in the control group (p = 0.3). The respective cure rates for bedwetting at 3 and 6 months post-operatively were 40 % and 50 % in the tonsillectomy group (p = 0.60), and 35 % and 48 % in the control group (p = 0.61). Similarly, no difference was seen in improvement or cure of daytime incontinence at 3 and 6 months post-operatively. The authors concluded that there was no association between tonsillar hypertrophy and urinary incontinence before or after tonsillectomy; tonsillectomy does not improve bedwetting.
Jeyakumar et al (2012) evaluated the prevalence of nocturnal enuresis in children diagnosed with sleep disordered breathing (SDB) and the effect of adenotonsillectomy (T&A) on nocturnal enuresis. Systematic review of the literature was performed using PubMed and Ovid. A systematic analysis of the literature was performed from 1980 to 2010 to identify children who had SDB and enuresis. A subset of children with enuresis who underwent T&A for SDB were also studied. A total of 14 studies were reviewed. A total of 3,550 children had SDB, of which one-third (n = 1,113) had a diagnosis of enuresis. Age range was 18 months to 19 years. A total of 7 studies (n = 1,360) had data on patients who underwent T&A for SDB with follow-up data on enuresis. The mean sample size was 194, with a median follow-up of 6 months and age range of 2 to 18 years. Pre-operative prevalence of enuresis was 31 % (426/1,360). A total of 587 children were followed after T&A. The post-operative prevalence of enuresis was 16 % (95/587; p < 0.0002, 2-tailed). Most studies did not make a distinction between primary and secondary enuresis. The age range of the subjects (18 months to 19 years) likely included some patients with developmentally acceptable enuresis. The authors concluded that SDB in children is associated with nocturnal enuresis. Adenotonsillectomy is associated with a significant improvement in enuresis in children with SDB. Moreover, they stated that there is a need for RCTs to examine the role of T&A in children with SDB and enuresis.
In a Cochrane review, Huang et al (2011) evaluated the effects of complementary interventions and others such as surgery or diet on NE in children, and compared them with other interventions. These investigators searched PubMed (1950 to June 2010), EMBASE (1980 to June 2010), the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS) (1984 to June 2010), Chinese Biomedical Literature Database (CBM) (1975 to June 2010), China National Knowledge Infrastructure (CNKI) (1979 to June 2010), VIP database (1989 to June 2010), and the reference lists of relevant articles, all last searched June 26, 2010. No language restriction was used. All randomized or quasi-randomized trials of complementary and other miscellaneous interventions for NE in children were included except those focused solely on daytime wetting. Comparison interventions could include no treatment, placebo or sham treatment, alarms, simple behavioral treatment, desmopressin, imipramine and miscellaneous other drugs and interventions. Two reviewers independently assessed the quality of the eligible trials, and extracted data. In 24 randomized controlled trials (RCTs), a total of 2,334 children were studied, of whom 1,283 received a complementary intervention. The quality of the trials was poor: 5 trials were quasi-randomized, 5 showed differences at baseline and 17 lacked follow-up data. The outcome was better after hypnosis than imipramine in 1 trial (relative risk (RR) for failure or relapse after stopping treatment 0.42, 95 % confidence interval (CI): 0.23 to 0.78). Psychotherapy appeared to be better in terms of fewer children failing or relapsing than both alarm (RR 0.28, 95 % CI: 0.09 to 0.85) and rewards (RR 0.29, 95 % CI: 0.09 to 0.90), but this depended on data from only 1 trial. Medicinal herbs had better results than desmopressin in 1 trial (RR for failure or relapse after stopping treatment 0.35, 95 % CI: 0.14 to 0.85). Acupuncture had better results than sham control acupuncture (RR for failure or relapse after stopping treatment 0.67, 95 % CI: 0.48 to 0.94) in a further trial. Active chiropractic adjustment had better results than sham adjustment (RR for failure to improve 0.76, 95 % CI: 0.60 to 0.95). However, each of these findings came from small single trials, and must be verified in further trials. The findings for diet and faradization were unreliable, and there were no trials including homeopathy or surgery. The authors concluded that there was weak evidence to support the use of hypnosis, psychotherapy, acupuncture, chiropractic and medicinal herbs but it was provided in each case by single small trials, some of dubious methodological rigour. They stated that robust RCTs are needed with efficacy, cost-effectiveness and adverse effects clearly reported.
Paruszkiewicz (2013) reviewed International Children's Continence Society guidelines on the recommended diagnostic evaluation and therapy for children with NE. Enuresis is characterized as monosymptomatic nocturnal enuresis (MNE) if there are no additional voiding problems. Children with other daytime symptoms (daytime incontinence, urgency, frequency) and NE are said to have non-monosymptomatic nocturnal enuresis (NMNE). A careful medical history, including bladder diary, physical examination, urinalysis, an ultrasound of the urinary tract system will usually provide sufficient information for the physician to arrive at a diagnosis. Urodynamic, radiologic and endoscopic evaluations are not necessary in children with MNE. Two first line treatment options of MNE are currently recommended: (i) non-pharmacologic treatment, and (ii) pharmacologic treatment (desmopressin). Non-pharmacologic treatment of enuresis includes motivational therapy, bladder-training exercises, fluid and food intake advice as well as enuresis alarm. Before using alarm treatment or desmopressin, simple therapeutic interventions should be considered. Children with nocturnal polyuria and normal bladder capacity will be more sensitive to desmopressin.
Dibianco et al (2014) provided a review of NE, including its epidemiology, etiology, pathophysiology, evaluation, and current management. These researchers also provided further insight on the treatment of this condition from the experience derived from patients cared for at their tertiary-care institution Nocturnal enuresis affects approximately 15 % of all children at 5-year old, affecting boys more frequently than girls. These investigators examined the condition in detail, highlighting specific goals of the initial evaluation and treatment. They contrasted the commonly implemented treatment recommendations, available from the literature with strategies they have found valuable from their extensive experience in treating patients with this disorder. Using current urologic reference textbooks, book chapters, Medline, journal articles and reviews describing the many aspects of NE were reviewed in order to describe NE and the current practices at their institution. Although, this was not a systematic literature review, it included relevant available research, institutional experience and urological expert opinion and current practices at a tertiary state health facility. The authors have established a treatment algorithm at their institution, which they have found successful in the majority of their patients. This consists of starting patients on urotherapy, then offering both the enuresis alarm device and medication therapy (desmopressin) as first-line treatments.
An UpToDate review on “Nocturnal enuresis in children: Management” (Tu and Baskin, 2015) states that “Desmopressin (a synthetic vasopressin analog) is a first-line treatment for enuresis in children older than five years whose bedwetting has not responded to advice about fluid intake, toileting, or an appropriate reward system. It is an alternative to enuresis alarms for children and families who seek rapid or short-term improvement of enuresis; have failed, refused, or are unlikely to adhere to enuresis alarm treatment; and for whom an enuresis alarm is unsuitable …. A review of complementary approaches such as hypnosis, psychotherapy, and acupuncture found limited evidence from small trials with methodologic limitations to support the use of such modalities for the treatment of nocturnal enuresis”.
