ABSTRACT

OBJECTIVES: Evaluate whether intraoperatively repaired lateral meniscus injuries impact midterm patient-reported outcomes in those undergoing operative fixation of tibial plateau fracture. DESIGN: Retrospective cohort study. SETTING: Level I trauma center. PATIENT SELECTION CRITERIA: All patients (n = 207) who underwent operative fixation of a tibial plateau fracture from 2016 to 2021 with a minimum of 10-month follow-up. OUTCOME MEASURES AND COMPARISONS: The Patient-Reported Outcomes Measurement Information System Physical Function, Knee Injury and Osteoarthritis Outcome Score, and the PROMIS-Preference health utility score. RESULTS: Overall, 207 patients were included with average follow-up of 2.9 years. Seventy-three patients (35%) underwent intraoperative lateral meniscus repair. Gender, age, body mass index, Charlson comorbidity index, days to surgery, ligamentous knee injury, open fracture, vascular injury, polytraumatic injuries, Schatzker classification, and Orthopaedic Trauma Association classification were not associated with meniscal repair ( P > 0.05). Rates of reoperation (42% vs. 31%, P = 0.11), infection (8% vs. 10%, P = 0.60), return to work (78% vs. 75%, P = 0.73), and subsequent total knee arthroplasty (8% vs. 5%, P = 0.39) were also similar between those who had a meniscal repair and those without a meniscal injury, respectively. There was no difference in Patient-Reported Outcomes Measurement Information System Physical Function (46.3 vs. 45.8, P = 0.707), PROMIS-Preference (0.51 vs. 0.50, P = 0.729), and all Knee Injury and Osteoarthritis Outcome Score domain scores at the final follow-up between those who had a meniscal repair and those without a meniscal injury, respectively. CONCLUSIONS: In patients with an operatively treated tibial plateau fracture, the presence of a concomitant intraoperatively identified and repaired lateral meniscal tear results in similar midterm PROMs and complication rates when compared with patients without meniscal injury. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

ABSTRACT

INTRODUCTION: Acute extremity compartment syndrome ("CS") is an under-researched, highly morbid condition affecting trauma populations. The purpose of this study was to analyze incidence rates and risk factors for extremity compartment syndrome using a high-quality population database. Additionally, we evaluated heritable risk for CS using available genealogic data. We hypothesized that diagnosis of extremity compartment syndrome would demonstrate heritability. MATERIALS AND METHODS: Adult patients with fractures of the tibia, femur, and upper extremity were retrospectively identified by ICD-9, ICD-10, and CPT codes from 1996 to 2020 in a statewide hospital database. Exposed and unexposed cohorts were created based on a diagnosis of CS. Available demographic data were analyzed to determine risk factors for compartment syndrome using logistic regression. Mortality risk at the final follow-up was evaluated using Cox proportional hazard modeling. Patients with a diagnosis of CS were matched with those without a diagnosis for heritability analysis. RESULTS: Of 158,624 fractures, 931 patients were diagnosed with CS. Incidence of CS was 0.59% (tibia 0.83%, femur 0.31%, upper extremity 0.27%). Male sex (78.1% vs. 46.4%; p < 0.001; RR = 3.24), younger age at fracture (38.8 vs. 48.0 years; p < 0.001; RR = 0.74), Medicaid enrollment (13.2% vs. 9.3%; p < 0.001; RR = 1.58), and smoking (41.1% vs. 31.1%; p < 0.001; RR 1.67) were significant risk factors for CS. CS was associated with mortality (RR 1.61, p < 0.001) at mean follow-up 8.9 years in the CS cohort. No significant heritable risk was found for diagnosis of CS. CONCLUSIONS: Without isolating high-risk fractures, rates of CS are lower than previously reported in the literature. Male sex, younger age, smoking, and Medicaid enrollment were independent risk factors for CS. CS increased mortality risk at long-term follow-up. No heritable risk was found for CS. LEVEL OF EVIDENCE: III.

ABSTRACT

BACKGROUND: Instability after reverse shoulder arthroplasty (RSA) is one of the most frequent complications and remains a clinical challenge. Current evidence is limited by small sample size, single-center, or single-implant methodologies that limit generalizability. We sought to determine the incidence and patient-related risk factors for dislocation after RSA, using a large, multicenter cohort with varying implants. METHODS: A retrospective, multicenter study was performed involving 15 institutions and 24 American Shoulder and Elbow Surgeons members across the United States. Inclusion criteria consisted of patients undergoing primary or revision RSA between January 2013 and June 2019 with minimum 3-month follow-up. All definitions, inclusion criteria, and collected variables were determined using the Delphi method, an iterative survey process involving all primary investigators requiring at least 75% consensus to be considered a final component of the methodology for each study element. Dislocations were defined as complete loss of articulation between the humeral component and the glenosphere and required radiographic confirmation. Binary logistic regression was performed to determine patient predictors of postoperative dislocation after RSA. RESULTS: We identified 6621 patients who met inclusion criteria with a mean follow-up of 19.4 months (range: 3-84 months). The study population was 40% male with an average age of 71.0 years (range: 23-101 years). The rate of dislocation was 2.1% (n = 138) for the whole cohort, 1.6% (n = 99) for primary RSAs, and 6.5% (n = 39) for revision RSAs (P < .001). Dislocations occurred at a median of 7.0 weeks (interquartile range: 3.0-36.0 weeks) after surgery with 23.0% (n = 32) after a trauma. Patients with a primary diagnosis of glenohumeral osteoarthritis with an intact rotator cuff had an overall lower rate of dislocation than patients with other diagnoses (0.8% vs. 2.5%; P < .001). Patient-related factors independently predictive of dislocation, in order of the magnitude of effect, were a history of postoperative subluxations before radiographically confirmed dislocation (odds ratio [OR]: 19.52, P < .001), primary diagnosis of fracture nonunion (OR: 6.53, P < .001), revision arthroplasty (OR: 5.61, P < .001), primary diagnosis of rotator cuff disease (OR: 2.64, P < .001), male sex (OR: 2.21, P < .001), and no subscapularis repair at surgery (OR: 1.95, P = .001). CONCLUSION: The strongest patient-related factors associated with dislocation were a history of postoperative subluxations and having a primary diagnosis of fracture nonunion. Notably, RSAs for osteoarthritis showed lower rates of dislocations than RSAs for rotator cuff disease. These data can be used to optimize patient counseling before RSA, particularly in male patients undergoing revision RSA.

ABSTRACT

OBJECTIVES: Compare patient-reported outcome measures between hyperextension varus tibial plateau (HEVTP) fracture patterns to non-HEVTP fracture patterns. DESIGN: Retrospective study. SETTING: Single academic Level 1 Trauma Center. PATIENT SELECTION CRITERIA: All patients who underwent fixation of a tibial plateau fracture from 2016 to 2021 were collected. Exclusion criteria included inaccurate Current Procedural Terminology code, ipsilateral compartment syndrome, bilateral fractures, incomplete medical records, or follow-up <10 months. OUTCOME MEASURES AND COMPARISONS: In patients who underwent fixation of a tibial plateau fracture, compare Patient-Reported Outcomes Measurement Information System-Physical Function, PROMIS Preference, and Knee Injury and Osteoarthritis Outcome Score (KOOS) between patients with a HEVTP pattern with those without. RESULTS: Two-hundred and seven patients were included, of which 17 (8%) had HEVTP fractures. Compared with non-HEVTP fracture patterns, patients with HEVTP injuries were younger (42.6 vs. 51.0, P = 0.025), more commonly male (71% vs. 44%, P = 0.033), and had higher body mass index (32.8 vs. 28.0, P = 0.05). HEVTP fractures had significantly more ligamentous knee (29% vs. 6%, P = 0.007) and vascular (12% vs. 1%, P = 0.035) injuries. Patient-Reported Outcomes Measurement Information System-Physical Function scores were similar between groups; however, PROMIS-Preference (0.37 vs. 0.51, P = 0.017) was significantly lower in HEVTP fractures. KOOS pain, activities of daily living, and quality-of-life scores were statistically lower in HEVTP fractures, but only KOOS quality-of-life was clinically relevant (41.7 vs. 59.3, P = 0.004). CONCLUSIONS: The HEVTP fracture pattern, whether unicondylar or bicondylar, was associated with a higher rate of ligamentous and vascular injuries compared with non-HEVTP fracture patterns. They were also associated with worse health-related quality of life at midterm follow-up. LEVEL OF EVIDENCE: Prognostic Level III.

ABSTRACT

Background: Tibial plateau fractures in skiers are devastating injuries with increasing incidence. Few studies have evaluated patient-reported outcomes and return to skiing after operative fixation of a tibial plateau fracture. Purpose: To (1) identify demographic factors, fracture characteristics, and patient-reported outcome measures that are associated with return to skiing and (2) characterize changes in skiing performance after operative fixation of a tibial plateau fracture. Study Design: Case series; Level of evidence, 4. Methods: We reviewed all operative tibial plateau fractures performed between 2016 and 2021 at a single level-1 trauma center. Patients with a minimum of 10-month follow-up data were included. Patients who self-identified as skiers or were injured skiing were divided into those who returned to skiing and those who did not postoperatively. Patients were contacted to complete the Patient-Reported Outcomes Measurement Information System-Physical Function domain (PROMIS-PF), the Knee injury and Osteoarthritis Outcome Score-Activities of Living (KOOS-ADL), and a custom return-to-skiing questionnaire. Multivariate logistic regression was performed with sex, injury while skiing, PROMIS-PF, and KOOS-ADL as covariates to evaluate factors predictive of return to skiing. Results: A total of 90 skiers with a mean follow-up of 3.4 ± 1.5 years were included in the analysis. The rate of return to skiing was 45.6% (n = 41). The return cohort was significantly more likely to be men (66% vs 41%; P = .018) and injured while skiing (63% vs 39%; P = .020). In the return cohort, 51.2% returned to skiing 12 months postoperatively. The percentage of patients who self-reported skiing on expert terrain dropped by half from pre- to postinjury (61% vs 29.3%, respectively). Only 78% of return skiers had regained comfort with skiing at the final follow-up. Most patients (65%) felt the hardest aspect of returning to skiing was psychological. In the multivariate regression, the male sex and KOOS-ADL independently predicted return to skiing (P = .006 and P = .028, respectively). Conclusion: Fewer than half of skiers who underwent operative fixation of a tibial plateau fracture could return to skiing at a mean 3-year follow-up. The knee-specific KOOS-ADL outperformed the global PROMIS-PF in predicting a return to skiing.

ABSTRACT

OBJECTIVES: To determine the impact of acute compartment syndrome (ACS) and identify cost drivers of 1-year total treatment costs for operative tibial plateau fractures. DESIGN: Retrospective review. SETTING: Level 1 trauma center. PATIENTS: 337 patients with tibial plateau fractures, 24 of which were complicated by ACS. OUTCOMES: The primary outcome was total treatment cost over the first year for operatively treated tibial plateau fractures. The secondary objective was to use regression analysis to identify significant cost drivers. RESULTS: The diagnosis of ACS was associated with 2.85 times higher total treatment cost ( P < 0.001). ACS demonstrated increased total treatment cost when controlling for polytrauma ( P < 0.001) and postoperative infection ( P < 0.001). Regression analysis identified 5 variables significantly associated with total cost of care: body mass index, injury severity score, ACS, staged external fixation, and locking fixation ( P < 0.001; R 2 = 0.57). The diagnosis of ACS had the largest impact on total cost with a 3.5× greater impact on cost compared with the next highest variable, staged external fixation. CONCLUSIONS: Tibial plateau fractures complicated by ACS are associated with 2.85 times higher treatment costs over a 1-year period. There were 5 significant variables identified by regression analysis with ACS having the highest impact on total treatment. Together, these 5 factors account for 57% of treatment cost variability. LEVEL OF EVIDENCE: Economic Level IV. See Instructions for Authors for a complete description of levels of evidence.

ABSTRACT

BACKGROUND: Both patient and implant related variables have been implicated in the incidence of acromial (ASF) and scapular spine fractures (SSF) following reverse shoulder arthroplasty (RSA); however, previous studies have not characterized nor differentiated risk profiles for varying indications including primary glenohumeral arthritis with intact rotator cuff (GHOA), rotator cuff arthropathy (CTA), and massive irreparable rotator cuff tear (MCT). The purpose of this study was to determine patient factors predictive of cumulative ASF/SSF risk for varying preoperative diagnosis and rotator cuff status. METHODS: Patients consecutively receiving RSA between January 2013 and June 2019 from 15 institutions comprising 24 members of the American Shoulder and Elbow Surgeons (ASES) with primary, preoperative diagnoses of GHOA, CTA and MCT were included for study. Inclusion criteria, definitions, and inclusion of patient factors in a multivariate model to predict cumulative risk of ASF/SSF were determined through an iterative Delphi process. The CTA and MCT groups were combined for analysis. Consensus was defined as greater than 75% agreement amongst contributors. Only ASF/SSF confirmed by clinical and radiographic correlation were included for analysis. RESULTS: Our study cohort included 4764 patients with preoperative diagnoses of GHOA, CTA, or MCT with minimum follow-up of 3 months (range: 3-84). The incidence of cumulative stress fracture was 4.1% (n = 196). The incidence of stress fracture in the GHOA cohort was 2.1% (n = 34/1637) compared to 5.2% (n = 162/3127) (P < .001) in the CTA/MCT cohort. Presence of inflammatory arthritis (odds ratio [OR] 2.90, 95% confidence interval [CI] 1.08-7.78; P = .035) was the sole predictive factor of stress fractures in GHOA, compared with inflammatory arthritis (OR 1.86, 95% CI 1.19-2.89; P = .016), female sex (OR 1.81, 95% CI 1.20-2.72; P = .007), and osteoporosis (OR 1.56, 95% CI 1.02-2.37; P = .003) in the CTA/MCT cohort. CONCLUSION: Preoperative diagnosis of GHOA has a different risk profile for developing stress fractures after RSA than patients with CTA/MCT. Though rotator cuff integrity is likely protective against ASF/SSF, approximately 1/46 patients receiving RSA with primary GHOA will have this complication, primarily influenced by a history of inflammatory arthritis. Understanding risk profiles of patients undergoing RSA by varying diagnosis is important in counseling, expectation management, and treatment by surgeons.

ABSTRACT

BACKGROUND: The outcomes of orthopaedic trauma are not solely determined by injury severity or surgical treatment. Studies of numerous orthopaedic outcomes have found that psychosocial factors are also important. Symptoms of anxiety have been linked to long-term pain and disability. Although the existence of a relationship between psychosocial factors and functional outcomes is accepted across multiple disciplines, quantification of this association in patients who have experienced orthopaedic trauma has remained limited. Measuring the anxiety experienced by these individuals and the association with long-term functional outcomes remain poorly understood. QUESTIONS/PURPOSES: (1) Is there an association between early postoperative anxiety symptoms and late recovery of self-reported physical function in patients with orthopaedic trauma? (2) What was the impact of other factors such as demographic variables and comorbidities on late recovery physical function scores, and how did the magnitude of these factors compare with the association with anxiety score? (3) Did patients who presented as trauma activations differ regarding their anxiety symptoms and late-recovery self-reported physical function? METHODS: A total of 1550 patients with lower extremity fractures and postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and physical function scores treated between January 1, 2014, and January 1, 2021, at an academic Level I trauma center in North America were assessed. We performed a bivariate regression between the initial PROMIS anxiety and physical function, as well as a multivariate regression including age, gender, BMI, and American Society of Anesthesiologists class to control for potential confounding variables. In a subgroup of 787 patients presenting as trauma activations, we performed a separate regression including Injury Severity Score. RESULTS: PROMIS anxiety was associated with decreased late-recovery physical function (ß = -2.64 [95% CI -3.006 to -2.205]; p < 0.001). The relationship between PROMIS anxiety and physical function remained after controlling for confounding variables in our overall cohort (ß = -2.54 [95% CI -2.93 to -2.15]; p < 0.001) and in the trauma activation cohort (ß = -2.71 [95% CI -3.19 to -2.23]; p < 0.001). Age and American Society of Anesthesiologists score were associated with worse PROMIS physical function scores, while being a man was associated with better PROMIS physical function scores (age: ß= -1.26 [95% CI -1.50 to -1.02]; American Society of Anesthesiologists class: ß=-2.99 [95% CI -3.52 to -2.46]; men: ß = 0.95 [95% CI 0.16 to 1.75]). There were no differences in initial anxiety symptoms or late-recovery physical function between patients who presented as trauma activations and those who did not. Injury Severity Scores were independently associated with worse function (ß = -1.45 [95% CI -2.11 to -0.79]. CONCLUSION: Initial patient self-reported anxiety is negatively associated with patient-reported physical function at the final follow-up interval in a broad cohort of patients with orthopaedic lower extremity injuries undergoing surgery. Identifying patients with high initial PROMIS anxiety scores may allow us to determine which patients will report lower functional scores at the final follow-up. Future investigations could focus on the effect of psychosocial interventions such as cognitive behavioral therapy and mindfulness on functional scores. LEVEL OF EVIDENCE: Level III, therapeutic study.

ABSTRACT

INTRODUCTION: The natural history of diaphyseal tibial butterfly fragments is poorly documented. Numerous studies have analyzed risk factors for nonunions in the tibial shaft with known factors including Gustilo classification, ASA class, and cortical contact. However, the healing potential and ideal management of nonsegmental butterfly fragments in this setting remains unknown. The aim of this study was to determine the nonunion rate of diaphyseal tibial fractures with a butterfly fragment. METHODS: A performed a retrospective review of patients at a single academic Level 1 Trauma Center from 2000-2020 who underwent intramedullary nailing of tibial shaft fractures. Those with non-segmental butterfly fragments (OTA/AO: 42-B) and minimum 12 month follow up were included. Morphologic measurements of butterfly fragments were performed to measure location, size, and displacement, and mRust scores at final follow up were calculated. Outcome measures were surgery to promote union, and mRust scores. RESULTS: A total of 99 patients were included with 21 patients requiring revision surgery to promote union. Thirty six patients had open fractures and 77% of patients were male with a mean age of 34 (range: 12-80). Average follow up was 19 months (3 months - 12 years). The most common location of the butterfly fragment was the anterior cortex (42%), with a mean length of 7.8cm (SD: 3.3) and width of 1.8cm (SD: 0.5cm). At final follow-up 37% of fractures had persistent lucency without callus at the site of the butterfly while only 31% of fractures had remodeled cortex. Average time to complete healing was 13.3 months. Open fractures with butterfly fragments were more likely to go on to nonunion than closed (44% vs 9.2%, p=<0.001). The length of the butterfly fragment was not different between the union and nonunion groups (7.7 vs 7.5, P=0.42). CONCLUSIONS: Open tibial shaft fractures with a butterfly fragment have a high risk of nonunion. Further research may seek to determine if adjunct treatment of butterfly fragments (ie inter-fragmentary compression) in the acute setting could improve healing rates.

ABSTRACT

BACKGROUND: To adequately utilize patient reported outcome scores in the clinical setting, accurate determination of a cohort-specific minimal clinically important differences (MCID) is necessary. The purpose of this study was to assess MCID for Patient Reported Outcome Information System Physical Function Scores (PROMIS®) Physical Function (PF) in a sample of patients who have undergone operative fixation for femur fractures. METHODS: All patients at a single Level 1 trauma center who were treated for operative femur fractures were identified by Current Procedural Terminology (CPT) codes (27,244, 27,245, 27,506, 27,507). PROMIS PF was collected as part of routine clinical care via computer adaptive testing (CAT). MCID calculations were performed using both anchor-based and distribution-based methods. RESULTS: A total of 182 patients with 723 score observations were included in the overall distribution-based analysis and 131 patients with 309 score observations were included in the anchor-based analysis. In the overall cohort, the average age was 53.1 (SD 22.3), and 45% of participants were female. MCID for PROMIS PF scores was 5.43 in the distribution-based method and 5.18 in the anchor-based method. Overall scores in the distribution group improved from mean of 27.4 (SD 7.0) at the first postoperative visit to a mean of 36.7 (SD 10.0) at a subsequent follow up visit. Overall scores in the anchor group improved from mean of 26.7 (SD 7.3) at the first postoperative visit to a mean of 37.5 (SD 9.3) at a subsequent follow up visit. CONCLUSIONS: This study identifies two MCID values (5.18, 5.43) based on two calculation methods for PROMIS physical function scores in the operative femur fracture population. This data could be helpful in targeting postoperative patients who fall below expected norms or in allowing clinical correlation with changes in surgical practice.

ABSTRACT

BACKGROUND: Evaluating the minimal clinically important differences (MCIDs) in patient-reported outcome scores is essential for use of clinical outcomes data. The purpose of the current study was to calculate MCID of Patient Reported Outcome Information System Physical Function (PROMIS PF) scores for ankle fracture patients. METHODS: All patients who underwent operative fixation for ankle fractures at a single level 1 trauma center were identified by Current Procedural Terminology code. PROMIS PF scores were collected. Patients had to complete an anchor question at 2 time points postoperatively to be included in this study. Anchor-based and distribution-based MCIDs were calculated. RESULTS: A total of 331 patients were included in the distribution-based analysis, and 195 patients were included in the anchor-based analysis. Mean age was 45.3 years (SD 17.5), and 59.4% of participants were female. MCID for PROMIS PF scores was 5.05 in the distribution-based method and 5.43 in the anchor-based method. CONCLUSION: This study identified MCID values based on 2 time points postoperatively for PROMIS PF scores in the ankle fracture population. Both methods of MCID calculation resulted in equivalent MCIDs. This can be used to identify patients outside the normal preoperative and postoperative norms and may help to make clinically relevant practice decisions. LEVEL OF EVIDENCE: Level I, diagnostic study, testing of previously developed diagnostic measure on consecutive patients with reference standard applied.

ABSTRACT

BACKGROUND: An understanding of femoral anteversion and neck-shaft angle (NSA) is essential to deliver optimal orthopaedic surgical care. Despite the importance, there is little research examining the relationship between femoral anteversion and the NSA in an adult population. This study sought to determine if there is a correlation between femoral neck shaft angle and version in skeletally mature adults using computed tomography (CT) scanograms. METHODS: Between January 2010 and June 2017, all skeletally mature patients who had received a CT scanogram of the lower extremity were reviewed. Exclusion criteria included: (1) radiographic evidence of osteoarthritis, (2) history of hip, femur, or knee surgery or trauma, (3) and anatomic abnormalities of the proximal femur including prior slipped capital femoral epiphysis or Legg-Calvé-Perthes disease. Both femoral version and NSA were measured by a musculoskeletal fellowship trained radiologist using CT scanograms. Correlation between femoral version and NSA was determined using coefficient of determination (R2) and Pearson correlation coefficient (r) for the group as a whole and for each sex. RESULTS: There was no statistical correlation between femoral version and NSA for either the entire cohort or for each sex. For the entire cohort, R2 = 0.0016 and r was 0.04 (p=0.45), for females, R2 = 0.0005 and r was 0.0224 (p=0.72), and for males, R2 = 0.0342 and r was 0.185 (p=0.07). CONCLUSION: There was no correlation between femoral version and NSA. This finding is beneficial for surgeons to understand the proximal femoral anatomy. Patients with an increased femoral NSA should not be assumed to have increased femoral anteversion. LEVEL OF EVIDENCE: Level III, Retrospective Cohort Study.

ABSTRACT

Yoga has become a popular form of exercise, recreation, and meditation for adults in the United States. As the popularity of both yoga and the incidence of hip replacements have both coincidentally increased over the last 2 decades, we imagine that the number of total hip replacement patients partaking in the practice of yoga has also increased. There are no clear guidelines available for yoga practice following hip replacement. To date, there have been no published reports of prosthetic hip dislocations during yoga.

ABSTRACT

BACKGROUND: Kenya's neonatal mortality rate remains unacceptably high, at 22 deaths per 1000 live births, with a third of those attributable to prematurity. Respiratory distress syndrome (RDS) is the single most important cause of morbidity and mortality in the premature neonate. Continuous positive airway pressure (CPAP) is a proven modality of therapy but is rarely used in low-resource settings. We report on the introduction of bubble CPAP (BCPAP), a low-cost method of delivering CPAP appropriate to our setting, by comparing survival-to-discharge before and after the technology was introduced. METHODS: The inpatient hospital records of all preterm infants (<37 weeks) diagnosed with RDS in the AIC Kijabe Hospital Nursery during two 18-month periods before and after the introduction of BCPAP (46 infants enrolled from 1 November 2007 to 30 April 2009 vs. 72 infants enrolled from 1 November 2009 to 30 April 2011) were reviewed. Differences in survival-to-discharge rates between the two time periods were analyzed. RESULTS: The survival-to-discharge rate was higher in Period 2 (after the introduction of BCPAP) than in Period 1 (pre-BCPAP) (85% vs. 61%, p = 0.007). Similarly, there were lower referral rates of preterm infants with RDS in Period 2 than Period 1 (4% vs. 17%, p = 0.037). CONCLUSION: BCPAP has contributed significantly to favorable outcomes for preterm infants with RDS at AIC Kijabe Hospital. The use of this simple technology should be considered and studied for expansion to all hospitals in Kenya that care for preterm infants.
