Inpatient care for uncomplicated bronchiolitis: comparison with Milliman and Robertson guidelines.

CONTEXT: Bronchiolitis is the most common lower respiratory tract infection in infancy. A recent Centers for Disease Control and Prevention report confirmed that hospitalization rates for bronchiolitis have increased 2.4-fold from 1980 to 1996. Controversies exist about optimal treatment plans. Milliman and Robertson recommend ambulatory care management; in case of hospitalization, the recommended length of stay is 1 day. OBJECTIVES: To relate actual practice variation for infants admitted with uncomplicated bronchiolitis to Milliman and Robertson's recommendations. DESIGN: Prospective observational study. SETTING: General care wards of 8 pediatric hospitals of the Child Health Accountability Initiative during the winter of 1998-1999. PATIENTS: First-time admissions for uncomplicated bronchiolitis in patients not previously diagnosed as having asthma and who were younger than 1 year. MAIN OUTCOME MEASURES: Respiratory rate, monitored interventions, attainment of discharge criteria goals, and length of stay. RESULTS: Eight hundred forty-six patients were included in the final analysis: 85.7% were younger than 6 months, 48.5% were nonwhite, and 64.1% were Medicaid recipients or self-pay. On admission to the hospital, 18.3% of the infants had respiratory rates higher than higher than 80 breaths per minute, 53.8% received supplemental oxygen therapy, and 52.6% received intravenous fluids. These proportions decreased to 1.9%, 33.8%, and 20.3%, respectively, 1 day after admission, and to 0.7%, 20.1%, and 8.6%, respectively, 2 days after admission. The average length of stay was 2.8 days (SD, 2.3 days). CONCLUSIONS: Milliman and Robertson's recommendations do not correspond to practice patterns observed at the hospitals participating in this study; no hospital met the Milliman and Robertson recommended 1-day goal length of stay. Administration of monitored intervention persisted past the second day of hospitalization.

Sustaining the implementation of an evidence-based guideline for bronchiolitis.

OBJECTIVE: To describe the changes occurring over a 3-year period after implementation of an evidence-based clinical practice guideline for the care of infants with bronchiolitis. DESIGN: Before and after study. SETTING: Children's Hospital Medical Center, Cincinnati, Ohio. PATIENTS: Infants 1 year or younger admitted to the hospital with a first-time episode of typical bronchiolitis. INTERVENTION: The guideline was implemented January 15, 1997. Data on all patients discharged from the hospital with bronchiolitis, from January 15 through March 27, in 1997, 1998, and 1999, were stratified by year and compared with data on similar patients discharged from the hospital in the same periods in the years 1993 through 1996. MAIN OUTCOME MEASURES: Patient volumes, length of stay for admissions, and use of specific laboratory and therapeutic resources ancillary to bed occupancy. RESULTS: After implementation of the guideline, admissions decreased 30% and mean length of stay decreased 17% (P<.001). Nasopharyngeal washings for respiratory syncytial virus were obtained in 52% fewer patients (P<.001); 14% fewer chest x-ray films were ordered (P<.001). There were significant reductions in the use of all respiratory therapies, with a 17% decrease in the use of at least 1 beta(2)-agonist inhalation therapy (P<.001). In addition, 28% fewer repeated inhalations were administered (P<.001); mean costs for all resources ancillary to bed occupancy fell 41% (P<.001); and mean costs for respiratory care services fell 72% (P<.001). CONCLUSIONS: An evidence-based clinical practice guideline for the care of patients encountered in major pediatric care facility has been successfully sustained beyond the initial year of its introduction to practitioners in southwest Ohio.

Differential markers for regionalization.

OBJECTIVE: To examine the site of delivery for very low birth weight (VLBW) infants and infants with major congenital malformations (MCM) within an established system of perinatal regionalization. STUDY DESIGN: A retrospective study of site of delivery for VLBW infants and infants born with MCM (tracheoesophageal fistula/esophageal atresia, diaphragmatic hernia, or gastroschisis/omphalocele) from 1990 through 1995 in Ohio. RESULTS: A total of 59.8% of VLBW infants and 36.1% of MCM infants were born in a level III hospital. There was a significant trend toward a decrease in VLBW infants (p < 0.01) and an increase in MCM infants (p < 0.05) born in a level III hospital between 1990 and 1995. There were significant regional variations among the six perinatal regions in Ohio in the proportion of both VLBW and MCM infants born in a tertiary center. CONCLUSION: Using the traditional marker of VLBW to assess regionalization in one state, we found significant variation in site of delivery among the perinatal regions and over the time course of the study. The delivery of infants with MCM at level III centers may be an alternative measure of regionalization.

Prenatal care and infant emergency department use.

OBJECTIVE: To determine the relationship between mothers' use of prenatal care and pediatric emergency department (ED) use by their infants in the first 3 months of life. METHODS: This is a retrospective, cohort-control study of well, full-term infants who use a children's hospital ED. Using logistic regression, the likelihood of an emergency visit in the first 3 months of life was compared between infants of women with fewer than two prenatal visits and infants of women with two or more prenatal visits. Covariates were maternal age, race, substance abuse history, parity, infant birth weight, insurance status, and distance from the ED. RESULTS: The odds of an ED visit before age 3 months by infants of mothers with less than two prenatal visits was 29% lower than the comparison group. ED use was increased by proximity, Medicaid or no health insurance and younger maternal age. Seventy percent (70%) of visits by both cohorts were classified as unjustified. The odds of making an unjustified ED visit were increased by younger maternal age and proximity to the emergency department. CONCLUSIONS: Women with poor prenatal care are less likely to seek ED care for their young infants. Although suboptimal prenatal care is associated with negative health outcomes, it is not known whether fewer infant ED visits are similarly deleterious.

Management of sore throats in children: a cost-effectiveness analysis.

OBJECTIVE: To perform a cost-effectiveness analysis of treatment management strategies for children older than 3 years who present with signs or symptoms of pharyngitis. DESIGN: Decision model with 7 strategies, including neither testing for streptococcus nor treating with antibiotics; treating empirically with penicillin V; basing treatment on results of a throat culture (Culture); and basing treatment on results of enzyme immunoassay or optical immunoassay rapid tests, performed alone or in combination with throat cultures. In these 7 strategies, all tests are performed in a local reference laboratory. In a sensitivity analysis, we examined the cost-effectiveness of 4 strategies involving office-based testing. We obtained data on event probabilities and test characteristics from our hospital's clinical laboratory and the literature; costs for the analysis were based on resource use. RESULTS: At a baseline prevalence of 20.8% for streptococcal pharyngitis, the Culture strategy was the least expensive and most effective, with an average cost of $6.85 per patient. The outcome was sensitive to the prevalence of streptococcal pharyngitis, the rheumatic fever attack rate, the cost of the enzyme immunoassay test, and the cost of culturing and reporting culture results. The Culture strategy was also preferred if amoxicillin was substituted for oral penicillin. For office-based testing, Culture was the least costly strategy, but treatment based on results of the optical immunoassay test alone had an incremental cost-effectiveness ratio of $1.6 million per additional life saved. CONCLUSION: In a setting with adherent patients, children with sore throats should generally get throat cultures in lieu of rapid streptococcus antigen tests.

Health system factors contributing to breastfeeding success.

OBJECTIVE: To identify and characterize health care system factors that contribute to successful breastfeeding in the early postpartum period. STUDY DESIGN: A prospective 8-week cohort study of 522 women at five area hospitals who had a vaginal delivery of a healthy, full-term single child and who intended to breastfeed. Mothers and infants had free access to each other for breastfeeding during the hospital stay. Data were obtained through chart review and surveys. In-person postpartum interviews in the hospital and 4- and 8-week telephone interviews were used to determine participants' perceptions of breastfeeding support by hospital personnel, home visit nurses, and family and friends. The hospital in-person interview with each mother was conducted before discharge to confirm maternal interest and intent to breastfeed. Questions were asked regarding breastfeeding information and support provided by medical and nursing personnel. Mothers were asked to rate the quality of information, as well as the degree of support they received for breastfeeding. Mothers also were asked to rate their hospital breastfeeding experience. A second interview was conducted by telephone 4 weeks after birth. The focus of this interview was to ascertain the rating of their breastfeeding experience, the quality of their interactions with health care professionals, and whether supplemental formula was being provided to the infant. If supplemental formula was being provided, the mothers were asked to quantify the volume and frequency of supplementation. A final telephone interview was conducted when the infants were 8 weeks of age. This interview determined the continuance or cessation of breastfeeding and information about formula supplementation, as in the 4-week interview. Mothers were given a journal and asked to note all telephone calls, clinic visits, and home nurse visits that related to breastfeeding issues and concerns. Demographic data examined included maternal age, marital status, highest level of education reached, race, employment, insurance coverage, and length of stay in the hospital. Pregnancy characteristics included prenatal care, parity, and gravity. Infant characteristics included gestational age and birth weight. Other factors examined included maternal rating of the support received from the infant's father for the decision to breastfeed, the time the infant spent in the mother's hospital room, and whether the infant was breastfed in the delivery room. RESULTS: The women were mostly white (90%), educated (82% had some college education), married, older (mean maternal age of 29.3 years), and insured (92% commercial). The primary outcome of interest was success at breastfeeding. Success was determined based on each mother's initial estimate of the planned duration of breastfeeding. Of the participants, 76% breastfed successfully for at least as long as they had initially planned. Seventeen percent of the mothers had stopped breastfeeding at the time of the 4-week interview, and 29% had stopped by the 8-week interview. Of the infants' fathers, 97% were reported by the mothers to be supportive of the decision to breastfeed. Once discharged, 98% of mothers expected to have help with the household chores. Eighty percent rated their hospital breastfeeding experience as good or very good. However, only 56% rated hospital breastfeeding support as good or very good, and only 44% spoke with a lactation consultant while in the hospital. Of those who spoke with the lactation consultant, 85% felt more confident afterward. Hospital nurses talked with 82% of women, and 97% of these found this helpful. Seventy-four percent reported receiving a home nursing visit after discharge, and of these, 82% found it helpful. Successful mothers were significantly more likely to report that the visiting nurse watched them breastfeed and asked how it was going. Mothers were more likely to call or visit family and friends with concerns about breastfeeding than

Evaluation of an evidence-based guideline for bronchiolitis.

OBJECTIVE: To describe the effect of implementing an evidence-based clinical practice guideline for the inpatient care of infants with bronchiolitis at the Children's Hospital Medical Center in Cincinnati, Ohio. METHODOLOGY: A multidisciplinary team generated the guideline for infants < or = 1 year old who were admitted to the hospital with a first-time episode of typical bronchiolitis. The guideline was implemented January 15, 1997, and data on all patients admitted with bronchiolitis from that date through March 27, 1997, were compared with data on similar patients admitted in the same periods in the years 1993 through 1996. Data were extracted from hospital charts and clinical and financial databases. They included LOS and use and costs of resources ancillary to bed occupancy. RESULTS: After implementation of the guideline, admissions decreased 29% and mean LOS decreased 17%. Nasopharyngeal washings for respiratory syncytial virus were obtained in 52% fewer patients. Twenty percent fewer chest radiographs were ordered. There were significant reductions in the use of all respiratory therapies, with a 30% decrease in the use of at least 1 beta-agonist inhalation therapy. In addition, 51% fewer repeated inhalations were administered. Mean costs for all resources ancillary to bed occupancy decreased 37%. Mean costs for respiratory care services decreased 77%. CONCLUSIONS: An evidence-based clinical practice guideline for managing bronchiolitis was highly successful in modifying care during its first year of implementation.guideline, bronchiolitis, evidence-based medicine, pediatrics, outcome research.

An evidenced-based clinical pathway for acute appendicitis decreases hospital duration and cost.

BACKGROUND/PURPOSE: In the pediatric population, appendicitis remains the most common surgical emergency encountered. The purpose of this study was to determine the impact of an evidence-based clinical pathway for acute appendicitis on patient care as well as hospital and home care costs at the authors' pediatric institution. METHODS: A prospective evaluation was conducted of an appendicitis clinical pathway (June 1996 through November 1996) compared with historical control patients (June 1994 through November 1994) not cared for by the pathway. RESULTS: Data (average +/- SD) for 120 pathway (P) patients were compared with 122 control (C) patients. Age (11.5 +/- 3.6 years for C v 11.2 +/- 3.9 years for P), rates of negative appendectomy (12.3% for C v 9.2% for P) and perforation (26.2% for C v 18.3% for P) were similar. Pathway patients with nonperforated appendicitis were more often discharged from the hospital within 24 hours (48% for C v 67% for P; P = .014) with lower hospital costs ($4,095 +/- $1,280 for C v $3,638 +/- $1,633 for P; P = .001). Pathway patients with perforated appendicitis had shorter hospitalization (185.2 +/- 59 hours for C v 113 +/- 44 hours for P; P = .0001) and lower hospital costs ($11,175 +/- $3,893 for C v $7,823 +/- $2,366 for P; P = .0001). CONCLUSION: An evidence-based appendicitis pathway decreased duration of hospitalization and cost without adversely affecting diagnosis or therapy. Clinical pathways for surgical diagnoses may prove useful as a means to minimize costs without compromising patient care.

Use of hospital-based services in the first three months of life: impact of an early discharge program.

OBJECTIVE: To assess the effect of an early discharge program on the use of hospital-based health care services in the first 3 months of life. DESIGN: Retrospective cohort study. SETTING: Metropolitan university hospital and a children's hospital. PATIENTS: Term infants cared for in a single term nursery, before and after implementation of an early discharge program. INTERVENTION: Early discharge program. METHODS: Linking of the birth hospital and the children's hospital records and chart review. OUTCOME MEASURES: Pattern of emergency department visits and rehospitalizations in the first 3 months of life. RESULTS: The early discharge group had a shorter stay, 32 +/- 21 hours (mean +/- SD) than the control group (48 +/- 22 hours). There was no effect of early discharge on mean age at rehospitalization, rehospitalization rate, or reason for rehospitalization. Twenty-eight percent of infants in both study and control groups had at least one emergency department visit by 3 months of age. There was no difference between study and control groups in mean age or frequency of emergency department visits. Maternal age and race had a significant effect on the odds of visiting the emergency department. For any maternal age, nonwhite mothers were more likely to visit the emergency department. CONCLUSIONS: Early discharge of newborn infants to inner city parents can be accomplished without increasing hospital-based resource use in the first 3 months of life provided coordinated postdischarge care and home visiting services are available.

The influence of day of life in predicting the inpatient costs for providing care to very low birth weight infants.

The purpose of this study was to test, refine, and extend a statistical model that adjusts neonatal intensive care costs for a very low birth weight infant's day of life and birth weight category. Subjects were 62 infants with birth weights below 1,501 g who were born and cared for in a university hospital until discharged home alive. Subjects were stratified into 250-g birth weight categories. Clinical and actual daily room and ancillary-resource costs for each day of care of each infant were tabulated. Data were analyzed by using a nonlinear regression procedure specifying two separate for modeling. The modeling was performed with data sets that both included and excluded room costs. The former set of data were used for generating a model applicable for comparing interhospital performances and the latter for comparing interphysician performances. The results confirm the existence of a strong statistical relationship between an infant's day of life and both total hospital costs and the isolated costs for ancillary-resource alone (P < 0.0001). A refined series of statistical models have been generated that are applicable to the assessment of either interhospital or interphysician costs associated with providing inpatient care to very low birth weight infants.

Physician variations and the ancillary costs of neonatal intensive care.

OBJECTIVE: To determine to what degree attending physicians contribute to cost variations in the care of ventilator-dependent newborns. DATA SOURCES: Clinical data were merged with hospital financial data describing daily ancillary care costs during the first two weeks of life for 132 extremely low-birthweight newborns. In addition, each patient's chart was reviewed and illness severity graded using both SNAP and CRIB scores. STUDY DESIGN: This was a retrospective cohort of infants with birth weights of less than 1,001 grams and respiratory distress syndrome requiring mechanical ventilation in the first day of life. From birth up to two weeks of life, each received care directed by only one of 11 faculty neonatologists in a single university hospital. Data were analyzed stratified by these physicians. t-Test, ANOVA, and chi-square were used to assess bivariate data. For continuous data, log linear regressions were used. PRINCIPAL FINDINGS: After controlling for illness severity, when stratified by physicians, there were significant variances in the costs of ancillary resources for the study infants (p < .0001). Twenty-nine percent of the variance was attributable to whether or not the hospital day included the use of a ventilator. Physician identity explained only 5.6 percent (p < .0001). CONCLUSIONS: Physician identity was significant but explained less than 6 percent of the total variance in ancillary costs. Whether or not a ventilator was used during care was far more important. We conclude that for very sick babies during the first two weeks of care, reducing variations in ancillary services utilization among neonatologists will yield only modest savings.

Control of methicillin-resistant Staphylococcus aureus in a neonatal intensive-care unit: use of intensive microbiologic surveillance and mupirocin.

OBJECTIVE: To describe the epidemiology and the interventions used to control two methicillin-resistant Staphylococcus aureus (MRSA) epidemics involving 46 infants with two fatalities in a neonatal intensive care unit (NICU). SETTING: A 50-bed, level III NICU in a university hospital. INTERVENTIONS: After traditional interventions failed to stop the first epidemic, an intensive microbiologic surveillance (IMS) program was developed. Cultures were obtained on all infants each week, and those colonized with MRSA were isolated. When an infant was found to be colonized with MRSA, cultures immediately were obtained on all surrounding infants. This was continued until no MRSA-colonized infants were found in the area. During the first epidemic, mupirocin was used in an attempt to eradicate the organism from the unit. RESULTS: All infants, colonized and noncolonized, and parents of and personnel working with colonized infants were treated simultaneously with 5 days of mupirocin. This failed to eradicate MRSA in colonized infants. The spread of MRSA ceased in the unit, but a second epidemic occurred 4 months later. This time, IMS alone was successful in quickly containing the epidemic, and MRSA disappeared from the unit after all colonized infants were discharged. Plasmid analysis demonstrated that the same strain was responsible for both outbreaks. CONCLUSIONS: IMS and isolation are effective in containing the spread of MRSA in an NICU. The use of mupirocin failed to eradicate the organism.

Optimal gentamicin therapy in preterm neonates includes loading doses and early monitoring.

Recent studies have suggested the inadequacy of an initial gentamicin 2.5 mg/kg standard dose in neonates and the need for a loading dose. The purpose of this prospective, randomized study was to compare initial peak and initial trough serum gentamicin concentrations (SGC) in neonates after a standard dose (2.5 mg/kg) or a loading dose (4 mg/kg) on the first day of life. A secondary objective of the study was to evaluate the use of two SGC drawn after the first dose in designing individualized dosage regimens, despite the many changes in gentamicin disposition that occur over the first week of life. Forty infants admitted to the NICU were randomized to receive either 2.5 or 4 mg/kg gentamicin. Individual gentamicin pharmacokinetic parameters were determined after the first dose. Initial peak SGC were > 5 mcg/ml in only 6% of neonates receiving 2.5 mg/kg, versus 94% of neonates receiving 4 mg/kg. The initial trough after the first dose was < 2 mcg/ml in 100% of patients receiving 2.5 mg/kg and only 39% of patients receiving 4 mg/kg. Using two SGC after the first dose successfully predicted steady state peaks in 13/16 infants and steady state troughs in 14/16 infants. Thus, standard treatment of 2.5 mg/kg gentamicin yields initial peak serum gentamicin concentrations < 5 mcg/ml in neonates while a 4 mg/kg gentamicin loading dose, combined with pharmacokinetic monitoring after the first dose, optimizes gentamicin therapy in neonates.

Use of health care services by inner-city infants in an early discharge program.

OBJECTIVE: To assess the use of health care services by inner-city infants enrolled in an early discharge program who received care in tertiary care children's hospital primary care clinic. DESIGN: Retrospective cohort study. SETTING: Large, metropolitan university hospital and a children's hospital. PATIENTS: Term infants cared for in a single full-term nursery, before and after implementation of a coordinated early discharge program, who received primary care at the children's hospital. INTERVENTION: The coordinated Early Discharge Program was characterized by in-hospital visits by hospital-based coordinating nurses, home visits by nurses from a home nursing agency, and communication with physicians for necessary adjustments in postdischarge care. METHODS: After linking birth hospital records and the children's hospital medical records, a retrospective chart review was performed to obtain maternal demographic information and birth hospital length of stay, as well as the infants' attendance at primary care clinic, immunizations, emergency department visits, and rehospitalization. MAIN OUTCOME MEASURES: Number of primary care visits in the first 3 months of life, completion of one series of immunizations by 3 months of life, and number of emergency department visits and rehospitalization during the first 3 months of life. RESULTS: The early discharge group (n = 253) had a significantly shorter birth hospital length of stay (35 +/- 24 hours, mean +/- SD) when compared with the control group (n = 212) (52 +/- 14 hours). The early discharge group was also younger than the control group at the first primary care visit, with significantly more infants visiting the primary care clinic in the first month of life. There was also a significant difference between the groups in the mean number of emergency department visits (early discharge = .61 visits/patient, control = .79 visits/patient) and the proportion of patients with no emergency department visits during the first 3 months of life (early discharge = 57%, control = 43%). There was no difference between the two groups in the proportion of infants completing one series of immunizations or in the number of infants rehospitalized during the study period. CONCLUSIONS: Coordinated early discharge with home nursing visits for inner-city infants may result in earlier use of primary care services. Furthermore, there is a significant decrease in use of the emergency department during the first 3 months of life, and no increase in rehospitalization.

Description and evaluation of a program for the early discharge of infants from a neonatal intensive care unit.

The effect of a cost-containment program focused on decreasing the lengths of hospital stay of high-risk neonates was assessed by comparison of discharge weights and lengths of stay for 257 study infants, discharged from a neonatal intensive care unit (NICU) after an early-discharge program began, with those of 477 control infants discharged during a prior 1-year period. Demographic data and costs, as well as data on emergency department use and hospital readmissions, were included in the comparisons. There was a significant decrease in mean discharge weight and length of stay for infants in the study group. During a 7-month period, an estimated 2073 days of hospital care and approximately $2,700,000 in hospital charges were saved, or $10,609 per infant discharged. The cost of instituting and maintaining the program was $120,413, or $468 per infant. Seven visits were made to the emergency department by the study infants during the first 14 days after discharge. One infant was readmitted for a 4-day hospital stay for suspected sepsis. Significantly earlier discharge of high-risk neonates produced a decrease in hospital charges without causing excessive morbidity. The success of the program was coincident and presumed related to the institution of multiple elements focused toward family support through early-discharge planning. The reduction in hospital charges was 30 times higher than program expenses.

Acuity scores as predictors of cost-related outcomes of neonatal intensive care.

OBJECTIVE: The Medicus Patient Classification System (PCS) and the lameter Acuity Index Method (AIM) are two proprietary scoring systems in common use for stratifying patient populations before making comparisons of the medical care they receive. In this study the validities of these scores were tested when the scores were used to evaluate cost-related elements of high-risk neonatal intensive care. METHODS: A total of 687 surviving inborn infants cared for in a university hospital newborn intensive care unit provided data for these analyses. The infants were stratified into the five diagnosis-related groups (DRGs) for surviving neonates (386, 387, 388, 389, and 390), as determined from their discharge diagnoses. Each infant's summed total of daily PCS scores, a single AIM score, and birth weight were extracted from the hospital's decision-support data files and used as independent variables in regression analyses to determine correlations with lengths of hospital stay, ancillary resource utilizations, and hospital charges. RESULTS: The Medicus scores, which are computed prospectively on a daily basis, when summed retrospectively, correlated highly with lengths of stay, ancillary resource utilization, and associated hospital charges. The lameter scores, which are assigned retrospectively, were far less predictive of these outcome variables and generally worse than birth weight in explaining outcome variances. CONCLUSIONS: Although in common use, the lameter AIM could not be validated as an appropriate method for assessing cost-related outcomes after newborn intensive care. The Medicus PCS produced daily scores that, when summed after patient discharge, correlated highly with the same outcome variables. There is a need to test further these and other proprietary methods now used to compare the cost-related elements of care provided by different hospitals and physicians.

Increased incidence of severe breastfeeding malnutrition and hypernatremia in a metropolitan area.

OBJECTIVE: To identify common characteristics among infants with breastfeeding malnutrition in a region with an increasing incidence of breastfeeding malnutrition. DESIGN: Retrospective case series. SETTING: A 361-bed regional tertiary care children's hospital in a 1.7 million population metropolitan area. PATIENTS CASE SERIES: five infants with severe breastfeeding malnutrition and hypernatremia admitted to a tertiary care children's hospital over a 5-month period. Retrospective case review: 166 infants admitted between 1990 and 1994 with the diagnosis of dehydration, hypernatremia, or malnutrition. MAIN OUTCOME MEASURES: Maternal characteristics, age at presentation, percent loss from birth weight, serum sodium, average age at birth hospital discharge, neurologic, or cardiovascular complications. RESULTS: Five infants were admitted to a children's hospital over a 5-month period with severe breastfeeding malnutrition and hypernatremia. The average weight loss at time of readmission was 23% (+/- 8%) from birth weight. The average presenting sodium was 186 +/- 19 mmol/L. Three suffered significant complications. From 1990 through 1994, there was a statistically significant (P < .05) annual increase in the number of infants admitted with breastfeeding malnutrition and hypernatremia. CONCLUSIONS: While breastfeeding malnutrition and hypernatremia is not a new problem, this cluster of infants represents an increase in frequency and severity of the problem and could be a consequence of several factors, including inadequate parent education about breastfeeding problems and inadequate strategies for infant follow-up.
