The cost of failure: The economic impact of failed primary closure in classic bladder exstrophy.

PURPOSE: Failure of primary closure in classic bladder exstrophy (CBE) is a significant cause of morbidity, and yet its relative economic impact has not been well characterized. The authors aim to determine whether CBE patients who underwent failed primary closure incur greater economic burden in the year following their successful closure than those patients who underwent a successful primary closure. MATERIALS AND METHODS: After institutional review board approval CBE patients who were successfully closed between 1993 and 2013 were identified in an institutional exstrophy-epispadias database. Patients who were never closed at the study institution and those who had no documented successful closure were excluded. Inpatient hospital charges, hospital costs, and professional fees were collected for the year following successful closure. RESULTS: 162 patients met the inclusion and exclusion criteria and accounted for 312 inpatient admissions in the year following and including their respective successful bladder closures. 62 of the patients failed their primary closure and the remaining 100 succeeded. Adjusting for covariates, patients who underwent successful primary closure experienced a reduction in inpatient hospital charges of $8497, hospital costs of $9046 and professional fees of $11,180 in the year following their successful closure compared to those patients who failed their primary closure. CONCLUSION: Apart from the self-evident financial advantages of a successful primary closure, namely the avoidance of reclosure, there appears to be a lasting negative financial impact of failed primary closure even after these patients undergo successful reclosure at the study institution.

Primary bladder exstrophy closure in neonates: challenging the traditions.

PURPOSE: We describe a novel approach to neonatal bladder exstrophy closure that challenges the role of postoperative immobilization and pelvic osteotomy. MATERIALS AND METHODS: We reviewed the primary management of bladder exstrophy at our institutions between 2007 and 2011. In particular we compared postoperative management in the surgical ward using epidural analgesia to muscle paralysis and ventilation in the intensive care unit. Clinical outcome measures were time to full feed, length of stay, postoperative complications and redo closure. Cost-effectiveness was also evaluated using hospital financial data. Data are expressed as median (range). Significance was explored by Fisher exact test and unpaired t-test. RESULTS: A total of 74 patients underwent primary closure without osteotomy. Successful closure was achieved in 70 patients (95%). A total of 48 cases (65%) were managed on the ward (group A) and 26 (35%) were transferred to the intensive care unit (group B). The 2 groups were homogeneous for gestational age (median 39 weeks, range 27 to 41) and age at closure (3 days, 1 to 152). Complications requiring surgical treatment were noted in 4 patients (8.3%) in group A and 3 (11.5%) in group B (p = 0.609). Length of stay was significantly shorter for the group managed on the ward (11 vs 18 days, p <0.0001). Median costs were $42,732 for patients admitted to the intensive care unit and $16,214 for those admitted directly to the surgical ward (p <0.0001). CONCLUSIONS: Primary closure of bladder exstrophy without lower limb immobilization and osteotomy is feasible. Postoperative care on the surgical ward using epidural analgesia results in shorter hospitalization.

Practice patterns and resource utilization for infants with bladder exstrophy: a national perspective.

PURPOSE: Substantial variability exists in bladder exstrophy care, and little is known about costs associated with the condition. We define the care patterns and first year cost for patients with bladder exstrophy at select freestanding pediatric hospitals in the United States. MATERIALS AND METHODS: We used the Pediatric Health Information System database to identify patients with bladder exstrophy born between January 1999 and December 2010 who underwent primary closure in the first 120 days of life. Demographic, surgical, postoperative and cost data for all encounters were assessed. Multivariate linear regression was used to examine the association between patient, surgeon and hospital characteristics and costs. RESULTS: Of the 381 patients who underwent primary closure within the first 120 days of life 279 (73%) did so within the first 3 days of life. A total of 119 patients (31%) underwent pelvic osteotomy, including 51 of 279 (18%) who underwent closure within the first 3 days of life, 38 of 67 (56%) who underwent closure between 4 and 30 days of life, and 30 of 35 (86%) who underwent closure between 31 and 120 days of life (p = 0.0017). Median inflation adjusted, first year cost in United States dollars per patient was $66,577 (IQR $45,335 to $102,398). Presence of nonrenal comorbidity and completion of primary closure after 30 days of life increased first year costs by 24% and 53%, respectively. Increased post-closure length of stay was associated with greater costs. CONCLUSIONS: At select freestanding United States pediatric hospitals the majority of bladder exstrophy closures are performed within the first 3 days of life. Most, but not all, patients undergoing closure after the neonatal period undergo osteotomy. The presence of nonrenal comorbidity and increased postoperative length of stay are associated with greater costs.

Economic impact of failed or delayed primary repair of bladder exstrophy: differences in cost of hospitalization.

PURPOSE: Patients with bladder exstrophy and failed primary newborn closure or who undergo delayed primary repair have suboptimal functional outcomes. We sought to determine whether these patients also have costlier, more resource intensive hospitalizations compared to patients who undergo neonatal primary closure. MATERIALS AND METHODS: We reviewed hospital coding records to identify patients who underwent surgical repair of classic bladder exstrophy at The Johns Hopkins Hospital between 1997 and 2006, and obtained charge records for each hospitalization. Total hospital charges (excluding professional fees) were inflation adjusted to year 2005 dollars. Cases were identified as newborn primary repair, delayed primary repair or reclosure of failed prior repair. RESULTS: Results of classic exstrophy repair were analyzed in 80 patients. A total of 34 procedures were newborn primary repairs, 15 were delayed primary repairs and 31 were reclosures of failed prior repair. All of the patients undergoing delayed primary repairs and reclosures underwent osteotomy, compared to only 21% of those undergoing newborn primary repair. Overall mean inflation adjusted hospitalization charge was $66,348 +/- $26,625 (range $29,689 to $179,403). Newborn closures were significantly less costly (mean charge $53,188 +/- $15,086) than either reclosure ($71,621 +/- $19,366) or delayed primary closure ($85,278 +/- $42,354, p <0.0001). Controlling for multiple variables in a regression model showed that the primary factors associated with charges were operative time, days in intensive care unit and length of stay. Length of stay and operative times were significantly shorter in the newborn surgical group, likely accounting for the lower costs in this group (despite higher intensive care unit use). Mean hospital charges and mean length of stay increased during the study period. CONCLUSIONS: Primary newborn exstrophy repair is associated with lower surgical hospitalization costs compared to delayed primary repair and reclosure. Combined with previous data on clinical outcomes, these data reiterate the paramount importance of achieving a successful initial newborn closure whenever possible.

Surgical repair of bladder exstrophy in the modern era: contemporary practice patterns and the role of hospital case volume.

PURPOSE: Bladder exstrophy is a rare condition, and data are lacking regarding practice patterns in its surgical management. We used a large nationwide database to investigate practice patterns of bladder exstrophy repair. MATERIALS AND METHODS: We used the Nationwide Inpatient Sample (1988 to 2000) to identify patients who underwent surgical repair of bladder exstrophy (International Classification of Disease-9 code 578.6). We analyzed factors affecting practice patterns and outcomes. Hospital volume was based on caseload during the highest volume year of study participation (high volume 5 or more, mid volume 3 to 4 and low volume less than 3 cases). RESULTS: We identified 407 cases. Approximately half of the patients (53.2%) were hospitalized within 24 hours of birth, although 28% of patients were older than 1 year. Of the patients 54% were male. Exstrophy repair is extremely resource intensive. In this series mean length of hospital stay (LOS) was 24.6 +/- 22.8 days, and mean inflation adjusted hospital charges were 62,302 dollars (median 39,978 dollars). High volume hospitals (HVHs) had lower hospital charges (37,370 dollars) than mid volume (51,778 dollars) or low volume hospitals (LVHs, 50,474 dollars, p = 0.0095). On multivariate regression HVHs had lower charges even after controlling for other significant predictors, including LOS (p <0.0001). Patients at HVHs were more likely to undergo osteotomy (p = 0.007). Six patients died after exstrophy repair (1.5%), all of whom had been born prematurely (p <0.0001). Although death was more likely at LVHs, this was due to the fact that more patients at LVHs were born prematurely (4.2% at HVHs vs 5.9% at mid volume hospitals and 11.1% at LVHs, p = 0.027). CONCLUSIONS: Bladder exstrophy repair carries a high risk of morbidity and is resource intensive. Variations between high and low volume hospitals in practice patterns and case mix may contribute to observed differences in resource use, LOS and clinical outcomes.

Bladder exstrophy in the newborn: a snapshot of contemporary practice patterns.

OBJECTIVES: To use a large nationwide database to investigate and describe practice patterns in the contemporary management of bladder exstrophy. METHODS: The Healthcare Cost and Utilization Project Nationwide Inpatient Sample (1988 to 2000) was queried to identify infants with bladder exstrophy hospitalized during the first week after birth. Admission and disposition patterns, resource utilization and length of stay, surgical repair trends, and factors associated with in-hospital death were analyzed. RESULTS: We identified 426 hospital admissions of newborns with exstrophy. Most patients (75%) were transferred in from, or out to, other facilities; this was a fundamental feature of early exstrophy care. Racial differences were evident, with Hispanics less likely to be transferred (19% versus 60%, P = 0.001). Among newborns who were not transferred, many (46%) were discharged without bladder surgery. Surgical repair was usually done in a hospital other than the birth hospital; the mean hospital charges for surgery were 75,742 dollars. Of the 5 patients who died after repair, all had undergone surgery at "low-volume" hospitals. The length of stay did not change significantly during the study period, helping to keep resource utilization high in this population. CONCLUSIONS: The results of this study provide a "snapshot" of bladder exstrophy practice patterns during the newborn period between 1988 and 2000. Additional research should investigate whether newborns with exstrophy are receiving optimal care, including appropriate timing of surgery, equitable transfers to tertiary centers, and reconstruction at centers with adequate volume and experience.

The exstrophy support team: a new concept in the care of the exstrophy patient.

The concept of the exstrophy support team is reported. It has extended the care of children with exstrophy into a lifelong continuum of effective assistence, not just by way of medical and surgical interaction but through knowledgeable and sympathetic coordination. There has been a spectacular improvement in over-all lifetime survival and much greater patient interest and appreciation with better followup and maintenance so that we can help quickly and effectively when problems arise. Now that we have achieved an increased longevity for these patients, we must be able to assure them the best possible quality of life.
