The Limited Utility of Routine Culture in Pediatric Pilonidal, Gluteal, and Perianal Abscesses.

BACKGROUND: Pilonidal, buttock, and perianal abscesses are common reasons for surgical consultation in the pediatric emergency department. Treatment typically includes a bedside incision and drainage, often followed by an abscess culture, and a course of oral antibiotics. We aimed to study the impact of culture data on changes in management and clinical outcomes. We hypothesized that management is unaffected by culture data, and therefore, fluid culture from pilonidal, buttock, and perianal abscesses in the pediatric population may represent an unnecessary laboratory test and cost. MATERIALS AND METHODS: A single institution's electronic medical record was searched between February 1, 2013 and August 1, 2017, identifying 249 pediatric patients meeting the inclusion criteria: age 0 to 18 y; diagnosis of pilonidal, buttock, or perianal abscess; bedside incision and drainage. Patients were divided into two different comparison groups for data analysis based on the presence or absence of culture and recurrence or no recurrence. RESULTS: Culture results directly altered management in only 5 patient encounters (2.7% of all cultured). When comparing groups by culture or no culture, no statistically significant difference in recurrence rate (P = 0.4) was noted. When comparing groups by recurrence versus no recurrence, we found no statistically significant difference between sex, resident type, vessel loop use, packing use, or antibiotic use (P > 0.05). CONCLUSIONS: We conclude that microbiological culture results are of limited utility in the management of pediatric pilonidal, buttock, and perianal abscesses as they do not appear to alter treatment, and omission of culture is not associated with failure of surgical management.

Risks and benefits of opportunistic salpingectomy during vaginal hysterectomy: a decision analysis.

BACKGROUND: Fallopian tubes are commonly removed during laparoscopic and open hysterectomy to prevent ovarian and tubal cancer but are not routinely removed during vaginal hysterectomy because of perceptions of increased morbidity, difficulty, or inadequate surgical training. OBJECTIVE: We sought to quantify complications and costs associated with a strategy of planned salpingectomy during vaginal hysterectomy. STUDY DESIGN: We created a decision analysis model using TreeAgePro. Effectiveness outcomes included ovarian cancer incidence and mortality as well as major surgical complications. Modeled complications included transfusion, conversion to laparotomy or laparoscopy, abscess/hematoma requiring intervention, ileus, readmission, and reoperation within 30 days. We also modeled subsequent benign adnexal surgery beyond the postoperative window. Those whose procedures were converted from a vaginal route were assumed to undergo bilateral salpingectomy, regardless of treatment group, following American College of Obstetricians and Gynecologists guidelines. Costs were gathered from published literature and Medicare reimbursement data, with internal cost data from 892 hysterectomies at a single institution used to estimate costs when necessary. Complication rates were determined from published literature and from 13,397 vaginal hysterectomies recorded in the National Surgical Quality Improvement Program database from 2008 through 2013. RESULTS: Switching from a policy of vaginal hysterectomy alone to a policy of routine planned salpingectomy prevents a diagnosis of ovarian cancer in 1 of every 225 women having surgery and prevents death from ovarian cancer in 1 of every 450 women having surgery. Overall, salpingectomy was a less expensive strategy than not performing salpingectomy ($7350.62 vs $8113.45). Sensitivity analysis demonstrated the driving force behind increased costs was the increased risk of subsequent benign adnexal surgery among women retaining their tubes. Planned opportunistic salpingectomy had more major complications than hysterectomy alone (7.95% vs 7.68%). Major complications included transfusion, conversion to laparotomy or laparoscopy, abscess/hematoma requiring intervention, ileus, readmission, and reoperation within 30 days. Therefore, routine salpingectomy results in 0.61 additional complications per case of cancer prevented and 1.21 additional complications per death prevented. A surgeon therefore must withstand an additional ∼3 complications to prevent 5 cancer diagnoses and ∼6 additional complications to prevent 5 cancer deaths. CONCLUSION: Salpingectomy should routinely be performed with vaginal hysterectomy because it was the dominant and therefore cost-effective strategy. Complications are minimally increased, but the trade-off with cancer prevention is highly favorable.

Factors influencing drainage setting and cost for cutaneous abscesses among pediatric patients.

OBJECTIVE: To evaluate the clinical and microbiological factors associated with skin and soft tissue infections drained in the emergency department (ED) vs operative drainage (OD) in a tertiary care children's hospital. METHODS: This was a cross-sectional study among children aged 2 months to 17 years who required incision and drainage (I&D). Demographic information, signs and symptoms, abscess size and location, and wound culture/susceptibility were recorded. Patient-specific charges were collected from the billing database. Multivariate regression analysis was used to determine factors determining setting for I&D and the effect of abscess drainage location on cost. RESULTS: Of 335 abscesses, 241 (71.9%) were drained in the ED. OD for abscesses was favored in children with prior history of abscess (odds ratio [OR], 3.18; 95% confidence interval [CI], 1.36-7.44; P = .01) and labial location (OR, 37.81; 95% CI, 8.12-176.03; P < .001). For every 1-cm increase in size, there was approximately a 26% increase in the odds of having OD (OR, 1.26; 95% CI, 1.11-1.44, P < .001). Methicillin-resistant Staphylococcus aureus was identified in 72% of the 300 abscesses cultured and 12.3% were clindamycin resistant. OD was more expensive than I&D in the ED. Per abscess that underwent I&D, OD is $3804.29 more expensive than I&D in the ED while controlling for length of stay. DISCUSSION: Clinical factors associated with OD rather than I&D in the ED included history of abscess, increased abscess length, and labial location. Microbiological factors did not differ based on I&D setting. For smaller, nonlabial abscesses, ED drainage may result in significant cost savings.

Multicentre observational study of outcomes after drainage of acute perianal abscess.

INTRODUCTION: Management of perianal abscesses has remained largely unchanged for over 50 years. The evidence for postoperative wound packing is limited and may expose patients to painful procedures with no clinical benefit and at considerable increased cost. METHODS: Patients were recruited in 15 UK centres between December 2013 and October 2014. Outcome measures included number of dressing (pack) changes, healing, recurrence, return to work/normal function, postoperative fistula in ano and health utility scores (EQ-5D™). Pain was measured before, during and after dressing change on a visual analogue scale. RESULTS: Some 141 patients were recruited (median age 39 (range 18-86) years). The mean number of dressing changes in the first 3 weeks was 13 (range 0-21), equating to an annual cost to the National Health Service of €6 453 360 in England alone per annum. Some 43·8 per cent of wounds were healed by 8 weeks after surgery and 86 per cent of patients had returned to normal function. Some 7·6 per cent of abscesses had recurred and 26·7 per cent of patients developed a fistula in ano by 6 months following surgery. Patients reported a twofold to threefold increase in pain scores during and after dressing changes. CONCLUSION: Recurrent abscess is rare and fistula occurs in one-quarter of the patients. Packing is painful and costly.

The impact of perianal disease in young patients with inflammatory bowel disease.

BACKGROUND: Perianal disease is a potentially significant source of morbidity for patients with inflammatory bowel disease (IBD). We sought to identify the impact of perianal disease on IBD outcomes in children, adolescents, and young adults. METHODS: We studied 12,465 inpatient admissions for patients ≤20 years old with IBD in 2009 using the Kids' Inpatient Database (KID). Patients were stratified by their principal diagnosis of ulcerative colitis (UC) or Crohn's disease (CD). Perianal disease (perianal abscess, anal fissure, or anal fistula), complex fistulas (rectourethral, rectovaginal, or enterovesical), and growth failure were defined by ICD-9 codes. Logistic regression was performed adjusting for CD or UC, gender, age, need for surgical intervention, fistulas, or growth failure. RESULTS: Of the 511 (4.1%) patients with perianal disease, 480 had CD (94%, p < 0.001). Girls were less likely to suffer perianal disease (OR = 0.63, CI 0.52-0.76, p < 0.001). Those with perianal disease were more likely to suffer complex fistulas (OR = 3.5, CI 1.98-6.20, p < 0.001) but less likely to suffer enteroenteral fistulas (OR = 0.30, CI 0.15-0.63, p = 0.001) than those without perianal disease. Perianal disease did not increase the incidence of growth failure (p = 0.997) but doubled the likelihood of an operation of any type during admission (p < 0.001). Additionally, patients with perianal disease spent on average 1.29 more days in the hospital (7.45 vs. 6.16 days, p < 0.001) and accrued $5838 extra in hospital charges (p = 0.005). CONCLUSIONS: Perianal disease in younger patients is associated with a longer length of stay, higher hospital charges, and increased rates of both perineal and abdominal operative procedures. These data support the notion that, similar to adults, the presence of perianal disease in pediatric Crohn's patients is associated with a more severe course.

Minimally invasive drainage of subcutaneous abscesses reduces hospital cost and length of stay.

OBJECTIVE: We compared outcomes among pediatric patients managed with minimally invasive (MI) packing techniques with those managed with traditional packing techniques for drainage of subcutaneous abscesses. METHODS: After institutional review board approval, medical records of children requiring drainage of subcutaneous abscesses between January 2010 and June 2011 were reviewed. Data were collected on patient demographics, abscess location, surgical procedure, microbiology cultures, and hospital length of stay (LOS). The hospital accounting system was queried for direct and indirect costs. We compared LOS and cost data among groups managed with MI versus traditional packing techniques. RESULTS: Incision and drainage was performed on 329 children (57.8% girls, 72% white, mean age of 43 months [range <1 to 218]). Of the total abscesses 198 (60.2%) were located in the groin/buttocks/perineum. Methicillin-resistant Staphylococcus aureus was identified in 74% of culture specimens. A total of 202 patients (61.4%) underwent packing and 127 (38.6%) underwent MI drainage. MI drainage ranged from 0% (0/110) in January to June 2010 to 34.6% (44/127) in the July to December 2010 transition period and reached 90.2% (83/92) in 2011 (P < 0.001). Median LOS decreased from 2 days (interquartile range 1-2) in the packing-only period to 1 day (interquartile range 1-2) in the predominantly MI period (P < 0.001). Hospital costs decreased with the transition to the MI technique (P < 0.001). MI drainage was associated with a $520 reduction in median direct costs and a $385 reduction in median indirect costs (P < 0.001). CONCLUSIONS: Soft tissue infections requiring incision and drainage are common in the pediatric population, with the majority caused by methicillin-resistant Staphylococcus aureus. Infections requiring drainage most frequently occurred in the diaper area of girls younger than 3 years old. Changing to an MI technique significantly decreased the hospital costs and LOS in our patient population.

Improved economic and clinical outcomes with oritavancin versus a comparator group for treatment of acute bacterial skin and skin structure infections in a community hospital.

BACKGROUND: Oritavancin is a lipoglycopeptide antibiotic with in vitro bactericidal activity against gram-positive pathogens indicated for use in adults with acute bacterial skin and skin structure infections (ABSSSI). Its concentration-dependent activity and prolonged half-life provide a convenient single-dose alternative to multi-dose daily therapies for ABSSSI. This retrospective cohort study was conducted to quantify the clinical and economic advantages of using oritavancin compared to other antibiotic agents that have been historically effective for ABSSSI. METHODS: Seventy-nine patients received oritavancin who had failed previous outpatient antibiotic therapy (OPAT) for cellulitis or abscess and were subsequently readmitted to the hospital as an inpatient between 2016 and 2018. These patients were compared to a cohort of 28 patients receiving other antibiotics following OPAT failure and subsequent hospitalization for these two infection types. The primary clinical end point was average length of stay (aLOS) and secondary endpoints included readmission rates for the same indication at 30 and 90 days after discharge and the average hospital cost (aHC). RESULTS: A total of 107 patients were hospitalized for treatment of cellulitis or abscess. Demographic characteristics of both the oritavancin and comparator groups were similar except for the presence of diabetes. The primary clinical endpoint showed a non-significant decrease in aLOS between the oritavancin group versus comparator (2.12 days versus 2.59 days; p = 0.097). The secondary endpoints revealed lower readmission rates associated with oritavancin treatment at 30 and 90 days; the average hospital cost was 5.9% lower for patients that received oritavancin. CONCLUSION: The results of this study demonstrate that oritavancin provides not only a single-dose alternative to multi-day therapies for skin and skin structure infections, but also a clinical and economic advantage compared to other antibiotic agents.

Pediatric lateral neck infections - Computed tomography vs ultrasound on initial evaluation.

OBJECTIVE: Review the evaluation of children with a deep lateral neck infection and define the impact of initial imaging modality on outcomes and costs. METHOD: Case series, pediatric patients <18 years of age admitted to a tertiary care hospital with lateral neck infection between 01/01/14-05/31/16 as identified by ICD-9 and ICD-10 codes: 289.3 (lymphadenitis, unspecified), 682.1 (cellulitis and abscess of neck), 683 (acute lymphadenitis), I88.9 (nonspecific lymphadenitis, unspecified), L02.11 (cutaneous abscess of neck), L03.221 (cellulitis of neck), and L03.222 (acute lymphangitis of neck). Patients were divided into two groups based on initial imaging modality: primary ultrasound or primary computed tomography. Differences in length of stay, type and total number of imaging studies obtained, number of procedures, hospital readmission, and hospital cost were compared between cohorts. RESULTS: There were 40 (31%) primary ultrasound and 88 (69%) primary computed tomography patients (128 total). Median length of stay was 46 (IQR: 25,90) hours (1.9 days) for primary ultrasound and 63 (IQR: 39,88) hours (2.6 days) for primary computed tomography patients (p = 0.33). Drainage was performed in 48% of both groups. Additional imaging occurred in 17 (43%) primary ultrasound and 18 (20%) primary computed tomography patients (p = 0.02). Readmission occurred in 8 patients (6.3%). Retropharyngeal infection was encountered in 13 patients (10%); this was only discovered in patients who had a computed tomography performed. Median cost per primary ultrasound patients was $5363 (IQR: 3011, 7920) and $5992 (IQR: 3450, 8060) for primary computed tomography patients. CONCLUSIONS: The primary imaging modality (ultrasound or computed tomography) used to work-up children with a lateral neck infection did not impact length of stay or hospital cost. However, a significant subset had a coexisting retropharyngeal infection that was only identified on computed tomography. Future studies are needed to identify appropriate criteria for imaging in the work-up of lateral neck infections.

Daptomycin versus vancomycin for complicated skin and skin structure infections: clinical and economic outcomes.

STUDY OBJECTIVE: To assess the effect of daptomycin compared with vancomycin on the clinical and economic outcomes in patients with complicated skin and skin structure infections. DESIGN: Prospective, open-label study. SETTING: Level 1 trauma center in Detroit, Michigan. PATIENTS: Fifty-three adult patients with complicated skin and skin structure infections at risk for methicillin-resistant Staphylococcus aureus (MRSA) infection who were treated with daptomycin and a matched cohort of 212 patients treated with vancomycin. INTERVENTION: Patients in the prospective arm received intravenous daptomycin 4 mg/kg every 24 hours for at least 3 days but not more than 14 days. Historical controls received at least 3 days of vancomycin dosed to achieve trough concentrations of 5-20 microg/ml. MEASUREMENTS AND MAIN RESULTS: Outcomes evaluated included blinded assessments of clinical resolution, duration of therapy, and costs. The most common diagnoses were cellulitis (31%), abscess (22%), and both cellulitis with abscess (37%). Microbiology differed significantly between groups, with S. aureus found in 27 patients (51%) in the daptomycin group and 167 patients (79%) in the vancomycin group and MRSA in 22 (42%) and 159 (75%), respectively (p<0.001). The proportions of patients with clinical improvement or resolution of their infections on days 3 and 5 were 90% versus 70% and 98% versus 81% in the daptomycin versus vancomycin groups, respectively (p<0.01 for both comparisons), and 100% at the end of therapy in both groups. Among patients with complete resolution of their infections (41 patients [77%] with daptomycin vs 89 patients [42%] with vancomycin, p<0.05), median duration of intravenous therapy was 4 and 7 days, respectively, (p<0.001), and hospital costs were $5027 and $7552 (p<0.001). CONCLUSIONS: Patients receiving daptomycin achieved more rapid resolution of symptoms and clinical cure and had a decreased duration of inpatient therapy compared with those receiving vancomycin. This study suggests that daptomycin is a cost-effective alternative to vancomycin for complicated skin and skin structure infections.

Role of socioeconomic factors in deep neck abscess: A prospective study of 120 patients.

OBJECTIVE: To assess the socioeconomic factors, presentation, aetiological factors, microbiology, and management of deep neck abscesses. DESIGN: Prospective study. SETTING: Tertiary health care centre. PATIENTS AND METHODS: We studied 120 patients with deep neck abscess who were managed in the department of otolaryngology between May 2004 and December 2005. RESULTS: There were 54 male patients (45%) and 66 female (55%) with ages ranging from 18 months to 60 years. Most of the patients were of low socioeconomic status and 84 (70%) were illiterate. None were aware of the predisposing factors and potential complications of deep neck abscess. Ninety-six (80%) had poor orodental hygiene with dental infections and extraction as the most common predisposing factor followed by recurrent oropharyngeal infections. The median duration of delay before the patient presented to us was 1 week, and only 6 (5%) were aware of the primary health services available in their locality. The most common site was the submandibular region. Pain, fever, and dysphagia were the most common presenting symptoms, and Staphylococcus aureus was the most common micro-organism. All patients were treated by incision and drainage, and 10 required emergency tracheostomy. All patients responded with no complications. CONCLUSION: Socioeconomic factors, particularly ignorance, illiteracy, and poverty, are important contributory factors towards the high incidence of deep neck abscess in developing countries.

Economic impact of the community-acquired methicillin-resistant Staphylococcus aureus epidemic on the Driscoll Children's Health Plan.

Cellulitis and abscess accounted for increasing percentages of inpatient (4.6-11.1%), outpatient (0.6-1.2%) and total (1.7-3.3%) expenses from 2001 through 2004. The per member per month expenses attributed to cellulitis and abscess increased from $0.74 in 2001 to $1.19 in 2004. The epidemic of community-acquired methicillin-resistant Staphylococcus aureus infections in children has had a significant economic impact on the Driscoll Children's Health Plan.

Bacteriological study in perianal abscess is not useful and not cost-effective.

BACKGROUND: The detection of gut organisms in perianal abscesses has been postulated to suggest an underlying communication with the anal canal. However, recent studies appear to contradict this observation. The aim of this study is to determine the value of bacteriological studies in perianal abscesses. METHODS: A retrospective study of all patients who have had a surgical drainage of their perianal abscesses with concomitant microbiological examination from January 2010 to December 2012 was performed. Patients with known underlying anal fistula, Crohn's disease or previous perianal operations were excluded. RESULTS: A total of 164 patients, median age of 42.0 years (range 8-87) comprising of 78.7% males formed the study group. Gut organisms were cultured in 143 (87.2%) samples while 12 (7.3%) demonstrated skin organisms and nine did not yield any bacterial growth (5.5%). Twenty-nine (17.7%) patients developed anal fistula and 34 (20.7%) patients had a recurrence of the perianal abscess. The median follow-up period was 1450 (14-2391) days. There was no significant association between the presence of gut organism and development of fistulas (odds ratio = 0.48; 95% confidence interval = 0.17-1.37) or recurrence of perianal abscess (odds ratio = 1.66; 95% confidence interval = 0.46-6.01). CONCLUSION: Bacteriological culture in perianal abscess is not useful for predicting the development of anal fistula or abscess recurrence. Hence, there is no need to perform this investigation on a routine basis.

Critical Analysis of Hospital Readmission and Cost Burden After Robot-Assisted Radical Cystectomy.

OBJECTIVE: To examine the occurrence and cost burden of hospital readmission within 90 days of robot-assisted radical cystectomy (RARC). Subjects/Patients (or Materials) and Methods: From 2003 to 2012, 247 patients underwent RARC with extracorporeal urinary reconstruction at a single categorical cancer hospital. Continent diversions were performed in 67% of patients. All readmissions within 90 days were included. Readmissions were defined as early (<30 days) and late (31-90 days) with multiple readmissions captured as separate events. Cost analysis was performed using average direct hospital cost. The Fisher exact test was used to determine differences in proportion of readmissions between patient groups, while logistic regression was used to identify predictors for readmission. RESULTS: Ninety-eight (40%) patients were readmitted to the hospital at least once within 90 days after RARC, of which 77% occurred within 30 days. Twenty-seven (11%) required two or more readmissions. Readmissions took place at a median of 13 days after initial discharge. The most common reasons for initial readmission were infections (41%) and dehydration (19%). Stratified by urinary reconstruction type, ileal conduit (dehydration), Indiana pouch (urinary-tract infection without sepsis), and Studer neobladder (sepsis and pelvic abscess) differed by readmission reason. In a multivariable analysis, estimated blood loss was a predictor for readmission (p = 0.05). Patients readmitted to the hospital had direct costs that were 1.42× those who did not require readmission. Readmissions for ileus contributed to the highest cost of readmission, although ureteral stricture, pelvic abscess, and sepsis were the most costly per day of hospitalization. Limitations include retrospective analysis as well as variable thresholds for readmission and costs. CONCLUSIONS: Hospital readmission rates after RARC are high and costs of readmission are significant. Most patients are readmitted within 30 days and infection and dehydration are common causes. Clinicians should be aware of diversion-specific readmission causes.

Management of Bartholin's cyst and abscess using the Word catheter: implementation, recurrence rates and costs.

OBJECTIVE: Bartholin's cysts and abscesses occur in about 2% of women. None of the surgical or conservative treatment approaches have been proven to be superior. The Word catheter is an outpatient treatment option, but little is known about aspects of implementing this therapy in an office setting. The present study's focus is on recurrence rates and organizational requirements of implementing outpatient treatment of Bartholin's cyst and abscess and compares costs of Word catheter treatment and marsupialization. STUDY DESIGN: Between March 2013 and May 2014 30 women were included in the study. We measured time consumed for treatment and follow-up and analyzed costs using the Word catheter and marsupialization under general anesthesia. We also assessed the ease of use of the Word catheter for application and removal using a standardized visual analog scale (VAS 1-10). RESULTS: Word catheter treatment was successful in 26/30 cases (87%). Balloon loss before the end of the 4-week treatment period occurred in 11/26 cases with a mean residence time of 19.1 (±10.0) days. None of the patients with early catheter loss developed recurrent cyst or abscess. Recurrence occurred in 1/26 cases (3.8%). Difficulty-score of application was 2 [1-10] and of removal 1 [1], respectively. Costs were € 216 for the treatment in the clinic as compared with € 1584/€ 1282 for surgical marsupialization with a one-night stay or daycare clinic, respectively. CONCLUSIONS: The present study indicates that the Word catheter is an easy to handle, low cost outpatient procedure with acceptable short-term recurrence rates. Treatment costs are seven times lower than for marsupialization.

Outbreaks of group A streptococcal abscesses following diphtheria-tetanus toxoid-pertussis vaccination.

Two outbreaks of group A streptococcal abscesses following receipt of diphtheria-tetanus toxoid-pertussis (DTP) vaccine from different manufacturers were reported to the Centers for Disease Control (CDC) in 1982. The clustering of the immunization times of cases, the isolation of the same serotype of Streptococcus from all cases in each outbreak, and the absence of reported abscesses associated with receipt of the same lots of vaccine in other regions of the country, suggest that each outbreak was probably caused by contamination of a single 15-dose vial of vaccine. The preservative thimerosal was present within acceptable limits in unopened vials from the same lot of DTP vaccine in each outbreak. Challenge studies indicate that a strain of Streptococcus from one of the patients can survive up to 15 days in DTP vaccine at 4 degrees C. Contamination of vials during manufacturing would have required survival of streptococci for a minimum of 8 months. Preservatives in multidose vaccine vials do not prevent short-term bacterial contamination. Options to prevent further clusters of streptococcal abscesses are discussed. The only feasible and cost-effective preventive measure now available is careful attention to sterile technique when administering vaccine from multidose vials.

Nosocomial abscess. Results of an eight-year prospective study of 32,284 operations.

This article details the results of 114 abscesses found after 32,284 operations during a 30-day prospective infection surveillance. Abscesses occurred more often after gastric/esophageal (3.6%), colonic/appendiceal (2.8%), and pancreatic/biliary (1.5%) operations. Abscesses were intra-abdominal (58%), pelvic/perineal (31%), and retroperitoneal (3%). The most common pathogens were Escherichia coli, enterococci, and Bacteroides organisms. Abscess symptoms appeared 10 +/- 6 days (mean +/- SEM) after surgery and were drained 8 +/- 8 days after onset of symptoms. Hospital stay from onset of symptoms to discharge was four times greater than that for wound infection. Twenty-seven patients (28%) died. Mortality was increased in patients older than 50 years and in those with renal failure or multiple abscesses. Nosocomial abscesses had a greater morbidity than would infection. Excessive expense and high mortality warrant infection surveillance for both wound infection and ongoing nosocomial abscesses.

Social, economic, and surgical anatomy of a drug-related abscess.

The "letting of pus" has been a surgical triumph throughout medical history. This study was initiated to expand our knowledge of the etiologic, economic, and surgical aspects of an abscess. The records of 651 patients undergoing intraoperative incision and drainage of an abscess over a 12-month interval were analyzed. The abscesses were due to injection of illicit street drugs in 421 patients (64.7%), perirectal, pilonidal or sweat gland inflammation in 118 patients (18%), complications of diabetes in 22 patients (3.4%) and a prior operative procedure in only 18 patients (2.8%). Fifty-three of the 421 patients with a drug-related abscess were randomly selected for an indepth review. Eighty-three per cent of the patients had positive cultures including 75 per cent with a single organism and 25 per cent with mixed flora. Staphylococcus aureus was present in 62 per cent of the cultures and 41 per cent of the isolates were methicillin resistant. The average length of hospitalization was 12.4 days with a range of 1 to 61 days. The average cost of hospitalization was $10,651 which increased to $24,383 if the patient had a mycotic aneurysm. The estimated annual cost of treatment of this sequela of injected illicit drugs was 6.9 million dollars in our hospital.

Intraoral drainage: recommended as the initial approach for the treatment of parapharyngeal abscesses.

OBJECTIVE: We sought to compare the efficacy, safety, and cost of intraoral drainage (IOD) of parapharyngeal abscesses (PPAs) in the pediatric population with those of the more commonly used external neck drainage (END). PATIENTS AND STUDY DESIGN AND SETTING: An 11-year retrospective review was conducted of all patients admitted to a tertiary-care, university-affiliated, pediatric hospital with a diagnosis of PPA. Patients were divided into 2 groups according to the treatment received (IOD or END) and were followed to 1 month postoperatively. All children referred to our institution with a final diagnosis of PPA were included in the study. OUTCOME: Outcome measures were duration of anesthesia, duration of postoperative intravenous antibiotics (DPOIA), length of postoperative hospital stay (LPOHS), and occurrence of complications. RESULTS: Fifteen patients underwent IOD, and 10 patients, END. IOD shortened anesthesia time by 31.7 minutes compared with END (P = 0.0003). IOD was associated with a decrease in DPOIA and LPOHS by 1.1 days (P = 0.1931) and 1.6 days (P = 0.0649), respectively. The cost of treatment was thereby reduced. No complications were encountered in either group. CONCLUSIONS: IOD is a safe and effective treatment for PPA in the pediatric population. It leads to decreased morbidity, shortened anesthesia time, and reduced economic burden.

Hospital charges for dental caries related emergency admissions.

PURPOSE: The purpose of this investigation was to develop and test a model for identifying hospital charges resulting from patient admissions through the emergency room of a children's hospital to manage pediatric nontraumatic dental disease. METHOD: Model development involved data identification and collection at Children's Medical Center of Dallas, Texas. Its utility was tested in 4 children's hospitals across the United States. RESULTS: The model proved effective in determining hospital charges for pediatric caries-related admissions. Diagnosis codes assigned at the time of admission were not specific enough to limit identification to nontraumatic dental admissions. Extensive review of patient records determined that only one-third of admitted patients identified by the model were caries-related admissions. Fifty-two children were identified who were admitted to the 5 children's hospitals in 1997 due to dental caries or its complications. Median hospital charge per admission was $3,223 and the total hospital charges for these 52 children was $250,000. CONCLUSIONS: More specific ICD-9 diagnosis codes should be developed to identify these patients.

Cost benefits of two dressings in the management of surgical wounds.

In this prospective randomized controlled trial of the cost benefits of the choice of dressings in acute surgical wounds left to heal by secondary intention, patients had their wounds dressed with either a traditional dressing (ribbon gauze soaked in proflavine) or a modern hydrofibre dressing. Results showed that the hydrofibre dressing, although more expensive than the ribbon gauze, facilitated an earlier discharge from hospital (P = 0.001). The total cost of the patient episode was less in the hydrofibre group (P = 0.01). In an average UK health authority of 300,000 population, 100 bed days a year could be saved releasing an overall potential saving of 55,000 Pounds. A modern hydrofibre dressing allows more effective use of scarce hospital beds and precious financial resources, while still maintaining high quality patient care. It is important that clinical specialists and purchasers of health care should be aware of this clinical and cost-effective advance in the management of acute surgical wounds.
