Prevalence and Impact of Feeding-Related Events on Hospital Stay in Preterm and Term Newborns.

BACKGROUND: Nursing assessment of milk flow regulation and associated apnea, bradycardia, and desaturation (ABD events) contribute to considerations for the discharge of newborns from the acute care setting. Research regarding infant feeding-related (FR) events (sucking and swallowing difficulties) and ABD events in moderate to late-preterm and full-term infants is lacking. PURPOSE: This study observes the impact of FR and ABD events during feeding on hospital length of stay (LOS) and healthcare utilization (cost) in moderate-to-late preterm newborns, as well as full-term infants. METHODS: In a retrospective study, bottle-fed infants admitted to the level II specialty care nursery of an academic community hospital in Southern California were observed for FR and ABD events. Statistical analyses were used to determine the impact of FR events on adjusted LOS, to evaluate the interaction between FR event status and adjusted LOS on total hospital charges, and to assess the statistical independence between FR events and diagnostic-related group severity. RESULTS: The full sample of patient records included 308 infants born between 32- and 44-week gestational age between April 1, 2018, and October 31, 2022. LOS was twice as long in infants who had FR events. Total median charges were higher in the group with FR events at $160,165 versus $64,380 with non-FR events. IMPLICATIONS FOR PRACTICE AND RESEARCH: Increased knowledge in the epidemiology and nursing care of infants experiencing milk flow regulation and associated ABD events is critical for informing practices and guidelines related to the prevention of related morbidities.

The Postural Tachycardia Syndrome (PoTS) Bladder-Urodynamic Findings.

OBJECTIVE: To evaluate the urodynamics (UDS) of patients with postural tachycardia syndrome (PoTS). METHODS: Patients with a confirmed diagnosis of PoTS referred by the department of neuro-cardiology to the neuro-urology were identified and their UDS were retrospectively reviewed. RESULTS: In total, 50 patients (47 = 94.0% female) with confirmed PoTS and available UDS were identified. Mean age of females and males was 32.4 and 28.2 years, P = .15. Intermittent self-catheterisation was being used by 15/47 (31.9%) females at assessment. Detrusor overactivity was observed in 6 females (12.8%) (all at end fill and associated with urgency). In total, 14 (29.8%) females had no sensation of filling. No patients had an "unsafe" bladder. In total, 15/47 (31.9%) of women were unable to void with UDS catheters. Straining was reported in 22/35 (68.8%) of females. The female bladder outflow obstruction index = PDetQmax - 2.2(Qmax) was over 5 in 10/28 (35.7%) and over 18 in 5 (17.9%). The bladder contractility index = PDetQmax + 5Qmax was under 100 in 18/28 (28.6%) women. CONCLUSION: The UDS of patients with "PoTS bladder" often demonstrate a poorly sensate but stable and safe bladder with functional obstruction and impaired bladder contractility that may necessitate straining or intermittent self-catheterisation.
