Full textObjective: To determine the efficiency of nerve blocks in decreasing length of stay and verbal pain scores postoperatively in pediatric and adolescent patients undergoing anterior cruciate ligament (ACL) surgery. Design: A retrospective chart review of approximately 900 patients that underwent ACL surgery at Children's Hospital Boston and Waltham between the years of 2007 and 2010 was conducted. Patients' American Society of Anesthesiologists physical classification system number, weight, gender, birthday, length of stay, verbal pain scores, blocks given and local analgesics within them, complications, Emergency Department visits, graft type, readmission rates, and if the stay was extended or not was collected. Kruskai-Wallis tests were run to test if the control group (those without nerve blocks) and those with nerve blocks had statistically different significances between pain scores and length of stay. Results: Including all patients, the mean length of stay was 22.37 hours with a minimum stay of 3.75 hours and a maximum stay of 103.9 hours. The majority of patients had ASA's of one (77.3%), with a smaller percentage having a score of two (22.2%) and three (0.5%). The most prevalent graft type used was the hamstring tendon autograft (67%). There was a statistically significant difference p less than .001 in the median length of stay between graft types, with the patellar tendon graft having the lowest length of stay. The most common type of block given was the femoral block which was given in 70.5% of cases, followed by the femoral-sciatic (17.2%), femoral/lateral femoral cutaneous (2.3%), femoral catheter (1.7%), fascia iliac (1.7%), femoral block with femoral catheter (0.5%), sciatic block with femoral catheter (0.3%), and femoral-sciatic block with femoral catheter (0.1%). Although there was no statistically significance in pain scores (p value =.940), or in length of stay (p value =0.110) between those who received blocks and those that did not; there was a statistically significant difference in both pain scores, p less than 0.004, and length of stay p less than 0.001 between the types of blocks given. Those who received femoral-sciatic blocks had the shortest median hospital stay (8.76 hours) within the group of patients that received the nerve blocks. Besides there being no statistically significance difference in length of stay between those that received blocks and those that did not, there was also no difference in rates of extended stay between those who received blocks and those that did not (p value =0.171) or between the types of blocks given (p score =0.161). When looking at the local anesthetics used in the blocks those who received ropivacaine had lower median pain scores than those receiving bupivacaine (p value =.025); however, the median length of stay was the same regardless of the anesthetic used (p value =0.518). There was no statistically significant difference in complications between those receiving blocks and those not (p value =0.163) or between block types (p value =0.217). The same is true with ED visits. Conclusions: Although our hypothesis that those who had blocks would have lower pain scores and lengths of stay compared to those not given blocks was proven wrong, the results do lead to the possibility of studies comparing the effectiveness of instead using femoral-sciatic blocks, especially in non-allograft cases. In addition, an extension of this study is currently underway with more controls to see if there is a difference between those given blocks and those who were not in length of stay that was not detected in our study.

Full textSpecific Aims: The objective of this study is to evaluate the effect of early blood glucose correction in the Emergency Department (ED) on hospital length of stay. Methods: This study has received institutional review board approval. This is a retrospective cohort study conducted in an academic medical institution. Diabetic patients with hyperglycemia in the ED between June 1st, 2011 and June 30th, 2012 were included. Patients were excluded if they were less than 18 or greater than 89 years of age, not admitted, had diabetic ketoacidosis or hyperglycemic hyperosmolar state, treated with insulin for hyperkalemia, trauma patients, or had an initial blood glucose value of 200 mg/dL or less. Patients were categorized into two groups based on blood glucose control achieved within the first 24 hours from triage. The primary outcome of this study was to compare hospital length of stay between the groups. Main Results: A total of 161 patients were included in this study. Baseline demographics between groups were statistically similar with the exception of gender (p=0.635), ethnicity (p = 0.149), and co-morbidities calculated by the Charlson Co-Morbidity Score (p = 0.112). Blood glucose values in the ED did not statistically correlate to hospital length of stay (p = 0.299), however, co-morbidities were predictive of hospital length of stay (p = 0.025). Conclusion: Early correction of blood glucose values in the ED are not associated with hospital length of stay.

Full textDetta masterexamensarbete utforskar möjligheten att använda maskin-inlärning för att förutspå vårdtiden för en patient då denne skrivs in på en vårdavdelning från akutvårds-avdelningen vid ett sjukhus. Huvudmålet för arbetet är att tillhandahålla en jämförelse av olika maskininlärnings-algoritmer och föreslå en algoritm som är lämplig att integrera i en mjukvara på sjukhuset. Resultaten visar att det är möjligt att nå en balanced accuracy på 0.72 vid inskrivningstillfället samt 0.75 vid en senare tidpunkt i vårdprocessen. Den föreslagna algoritmen var Random Forest som kombinerade bra prestanda med effektiv träningstid, något som gör den lämplig för att köras på sjukhuset. Projektet visar att det finns en tydlig potential för att använda maskininlärning för att prediktera vårdtid men att förbättringar krävs innan det kan nå hela vägen in i sjukhuset.

Full textBackground: Undernutrition is highly prevalent in hospitalized patients worldwide and this condition has been associated with increased hospital length of stay (LOS). The diagnosis of undernutrition includes anthropometric measurements. The aim of this study was to measure the independent association of the anthropometric and derived indicators triceps skinfold thickness (TST), mid-upper arm circumference (MUAC), adductor pollicis muscle thickness (APMT), mid-upper arm muscle area (AMA) and mid-upper arm muscle circumference (AMC) with LOS, within a varied group of hospitalized patients. Methods: A total of 695 patients were enrolled in a prospective observational study, conducted in a Portuguese university hospital. Participants were dichotomized for the anthropometric and derived indicators TST, MUAC, APMT, AMA and AMC according to the percentiles 5th and 25th described in the literature, except for APMT, for which only the 5th percentile was used. Cox regression analysis was used to estimate adjusted hazard ratios (HR) and corresponding 95% confidence intervals (95% CI). Results: Patients that presented values lower than the 5th percentile for TST (HR=0.759, 95% CI=0.579;0.995), MUAC (HR=0.822, 95% CI=0.687;0.983), APMT (HR=0.791, 95% CI=0.671;0.933), AMA (HR=0.797, 95% CI=0.660;0.962) and AMC (HR=0.746, 95% CI=0.611;0.911), showed a lower probability of being discharged from the hospital to usual residence over time. For TST (HR 0.798, 95% CI=0.673;0.946), patients whose values were below the 25th percentile also presented a lower probability of being discharged from the hospital to usual residence over time. Conclusion: For all the anthropometric and derived indicators studied, patients that presented values lower than the 5th percentile had a lower probability of being discharged from the hospital to usual residence. For TST, values below the 25th percentile were also associated with lower probability of discharge. Thus, TST was found to be the best anthropometric indicator to predict LOS. This anthropometric indicator can present advantages for the diagnosis of undernutrition since it may allow an earlier detection of a poor nutritional status.
Introdução: A desnutrição apresenta elevada prevalência em doentes hospitalizados e esta condição tem vindo a ser associada com maior tempo de internamento (TI). O diagnóstico da desnutrição inclui indicadores antropométricos. O objetivo deste trabalho foi estudar a associação independente entre os indicadores antropométricos prega cutânea tricipital (PCT), perímetro do meio braço (PB), espessura do músculo adutor do polegar (AP), área muscular do braço (AMB) e perímetro muscular do braço (PMB) e o TI em doentes hospitalizados. Métodos: 695 indivíduos participaram num estudo observacional realizado num hospital universitário Português. Os participantes foram dicotomizados para cada indicador antropométrico PCT, PB, AP, AMB e PMB de acordo com os percentis 5 e 25 descritos na literatura, exceto para o AP, para o qual apenas o percentil 5 foi utilizado. Utilizaram--se modelos de regressão de Cox para calcular os hazard ratios (HR) e os intervalos de confiança a 95% (IC 95%) correspondentes. Resultados: Os participantes que apresentaram valores abaixo do percentil 5 para PCT (HR=0,759; IC 95%=0,579;0,995), PB (HR=0,822; IC 95%=0,687;0,983), AP (HR=0,791; IC 95%=0,671;0,933), AMB (HR=0,797; IC 95%=0,660;0,962) e PMB (HR=0,746; IC 95%=0,611;0,911), revelaram uma menor probabilidade de alta para o domicílio. Para a PCT (HR=0,798; IC 95%=0,673;0,946), apresentar valores abaixo do percentil 25 também se associou a uma menor probabilidade de alta para o domicílio. Conclusão: Os participantes que apresentaram valores abaixo do percentil 5 para todos os indicadores antropométricos mostraram uma menor probabilidade de alta domiciliar. Para a PCT, o percentil 25 também foi associado com uma menor probabilidade de alta para o domicílio. A PCT foi então o melhor indicador antropométrico capaz de prever o TI hospitalar. Incluir este indicador antropométrico nos métodos de diagnóstico de desnutrição pode ser uma mais valia por poder detetar mais precocemente um pior estado nutricional.

Full textThis project tries to assess whether hospitals react to random demand pressure by discharging patients earlier than expected. As a matter of fact, combining an unpredictable demand for medical services with limited and, to some extent, fixed medical resources, generates strong incentives to discharge patients earlier than expected when demand is high - increasing the risk of readmission and decreasing the benefit from treatment. This work was conducted as a way to determine whether those incentives actually affect discharging decisions. Analysis of Portuguese hospitals data shows that hospital utilization levels at the time of admission, prior to the admission and post admission do have a negative impact over the length of stay in hospital, although this impact is quantitatively irrelevant. More than that, larger utilization levels have a positive impact over the probability of being discharged at certain days of the week, indicating that an early discharges problem may exist.
