Background: The incidence of neonatal opioid withdrawal syndrome (NOWS), a drug withdrawal syndrome mainly associated with opioid exposure in-utero has significantly increased in the United States over the last decade with infants with NOWS staying longer in the hospital than those without NOWS. Objectives: To determine if feeding tube use while on admission is associated with length of hospital stay among infants diagnosed with NOWS. We also compared the differences between infants with NOWS who required the use of feeding tubes while on admission, and those that did not, based on infant and maternal characteristics. Methods: This was a retrospective cohort study of infants delivered between July 1, 2011 and June 30, 2016 at Ballad Health System. Our inclusion criteria were infants who were exposed to opioids in-utero and received a diagnosis of NOWS based on 2 consecutive Finnegan scores of 10, or 3 consecutive scores of 8, or treatment with morphine. Medical chart record of 294 infants who met these criteria were reviewed for infant and maternal characteristics. Our outcome variable was infant length of hospital stay and our predictor variable was feeding tube use an indicator for feeding difficulties. Chi-square test and t-test were used to compare infant and maternal characteristics by feeding tube use. Simple linear regression models were used to assess the effect of feeding tube use and infant and maternal characteristics on infant length of hospital stay. Multiple linear regression was used to model infant length of hospital stay predicted by feeding tube use, while adjusting for neonatal intensive care unit (NICU) admission, treatment with morphine, and maternal benzodiazepine use during pregnancy. All analyses were done using SAS 9.4. Results: Of the 294 infants diagnosed with NOWS, 22.11% had feeding difficulties that necessitated use of feeding tubes. Infants who used feeding tubes were significantly more likely to be born preterm (20.31% vs 8.73%, p=0.0096) to be admitted into the NICU (98.46% vs 51.09%, p=

Prompt diagnosis and treatment of necrotizing fascitis reduces the morbidity and mortality rates of this devastating disease. To examine the clinical outcomes of using negative pressure wound therapy in the adjunctive management of wounds secondary to necrotizing fascitis, a retrospective review of medical records was conducted. Participants included 11 consecutive patients (16 wounds) with a diagnosis of necrotizing fascitis admitted to a teaching hospital between 2000 and 2005 and treated on an inpatient basis with negative pressure wound therapy. The patients included seven men, four women (average age 54 years; range 18 to 82 years). Variables abstracted from the medical records and consultation notes included: demographic information, tissue and blood bacteriological data, wound history, wound healing outcomes, duration of negative pressure wound therapy, length of hospital stay, and mortality and morbidity information. Variables were entered into an electronic database and analyzed. Operative tissue biopsies were obtained and all participants received serial surgical debridements as well as infection, nutrition, and hemodynamic support. Negative pressure wound therapy was applied to the wound(s) at 125 mm Hg continuous negative pressure until reconstructive closure could be performed. Most wounds (10) were on lower extremities, seven patients presented with sepsis, and beta-hemolytic Streptococcus was identified in nine wounds. Mean number of negative pressure wound therapy treatment days was 25 (range: 7 to 74), mean length of stay was 67 days (range: 21 to 186). All wounds were successfully closed ĝ€" 73% received split-thickness skin grafts, 27% required flaps, 100% limb salvage was achieved, and all patients survived. No negative pressure wound therapy or dressing-associated complications were observed. Negative pressure wound therapy was found to be a viable adjunctive treatment in the management of wounds associated with necrotizing fascitis.

Hepatocellular carcinoma (HCC) is the second most common cancer in Taiwan and transcatheter arterial chemoembolization (TACE) is now the mainstay of treatment for noncurative HCC. Due to increasing medical costs yearly and financial problem of the Bureau of National Health Insurance, it is important to reduce medical resource utilization including hospital stay and medical costs. The aim is to figure out the risk factors of extended hospital stay, and increased in-hospital medical costs in hepatocellular carcinoma patients receiving transcatheter arterial chemoembolization. The result of this study should be available for further improvement of medical care quality in the limited medical resource. From January 2008 to January 2010, 162 patients (121 male and 41 female) with histologically proven hepatocellular carcinoma underwent TACE only (131 pts) or TACE followed by catheter placement for hepatic artery infusion chemotherapy (HAIC) (31pts) at district teaching hospital. The extended hospital stay (EHS) and extended post-procedure stay (EPS) are defined as stay larger than their median values (11 & 7 days respectively). Clinical demographic, disease factors, tumor factors, procedure (TACE)-related factors and complications are used to identify the univariate factors related to EHS and EPS statistically. To find out predictors of EHS, EPS and increased in-hospital medical costs, multiple linear regression analyses are used. The risk factors for EPS are procedure-related, including complications and procedure methods ( TACE + HAIC related to TACE only) (R2=.367, p<.001), while those for EHS are complications, encephalopathy, procedure methods, Child-Pugh classification C (related to classification A) and age (R2=.490, p<.001). The predictors for increased in-hospital medical costs include procedure methods, AJCC stage IV, T4 stage, hepatoencephalopathy and complications (R2=0.615, p<.001). Taking total hospital stay into consideration, the most important risk factor related to increased medical cost is total hosptial stay itself. The most powerful risk factor for EPS, EHS is procedure-related complication. The different procedure methods also affect hospital stay and medical costs. In order to reduce medical resource utilization, we should avoid post-procedure complication and pay attention to cirrhotic degree as well as American Joint Committee of Cancer (AJCC) tumor stage system. The result of this study can provide some ideas to adjust medical expense polices for the Bureau of National Health Insurance and to control medical cost for the hospitals.

Abstract Hospital treatment of chronic obstructive pulmonary disease in primary and secondary health care and changes in treatment from 1972 to 2004 were examined by means of the treatment register and the register of deaths. During the study period, the patients with a principal diagnosis of chronic obstructive pulmonary disease (COPD) underwent 356,066 treatment periods. In 1980–1984, 44.3% of the patients hospitalized the first time for COPD died within five years after their treatment period, and in 1990–1994, 50.9% died after their treatment period. According to Cox’s age-adjusted regression model, mortality increased among both men (Hazard Ratio 1.093, 95% CI 1.055–1.133) and women (HR 1.138, 95% CI 1.061–1.221). The number of long-term, over-90-day periods of inpatient treatment of COPD patients in university and central hospitals decreased 97.6% and the number of days of treatment decreased 98.4% between 1972–1976 and 1997–2001. Correspondingly, these treatment periods increased 7.6% in primary care hospitals and the number of days of treatment decreased 47.6%. In 1995–2001 the number of inpatient periods due to acute exacerbations of COPD increased 10.9%, but the number of days of treatment decreased 8.5%. The growth in age-adjusted treatment periods was 0.8% among men and 18.5% among women. The number of treatment periods increased 36.8% in general practice wards and 17.8% in wards for respiratory diseases, while they decreased 22.3% in internal medicine wards. General practitioners sent 5.1% of patients admitted to a primary care hospital with acute exacerbation of COPD to a secondary care hospital. The age- and gender-adjusted risk of death of patients managed by a general practitioner was 0.83 (95% CI 0.75–0.91) compared with those managed by a pulmonary specialist. Patients treated in primary care had a 1.74 times greater risk of being readmitted within a week after being released from inpatient treatment for acute exacerbations of COPD compared with patients treated in secondary care. The strategic policies of the 1980s, changes in the service structure, the national guidelines for the prevention and treatment of COPD issued in 1998, the valid treatment recommendation, and new treatments and medication have made treatment of COPD patients more effective. The emphasis has shifted to outpatient care and primary health care, where sufficient resources and education must be insured in order to guarantee good quality. / Tiivistelmä Tutkimuksessa selvitettiin hoitoilmoitus- ja kuolinsyyrekisterin avulla keuhkoahtaumataudin sairaalahoitoa ja sen muutoksia perusterveydenhuollossa ja erikoissairaanhoidossa vuosina 1972–2004. Tutkimusaikana oli 356 066 hoitojaksoa niillä potilailla, joiden päädiagnoosi oli keuhkoahtaumatauti (KAT). Vuosina 1980–1984 olleen ensimmäisen KAT:sta aiheutuneen sairaalahoitojakson jälkeen potilaista kuoli viiden vuoden kuluessa 44,3 % ja vastaavasti vuosien 1990–1994 hoitojakson jälkeen 50,9 %. Coxin regressiomallilla iän ollessa vakioituna kuolleisuus lisääntyi sekä miehillä (Hazard Ratio 1,093, 95 % CI 1,055–1,133) että naisilla (HR 1,138, 95 % CI 1,061–1,221). Pitkäaikaiset, yli 90 hoitopäivää jatkuneet, sairaalahoitojaksot vähenivät KAT-potilailla yliopisto- ja keskussairaaloissa 97,6 % ja hoitopäivät 98,4 % ajanjaksojen 1972–1976 ja 1997–2001 välillä. Vastaavasti terveyskeskussairaaloissa nämä hoitojaksot lisääntyivät 7,6 % ja hoitopäivät vähenivät 47,6 %. Vuosina 1995–2001 olleiden KAT:n akuuttien pahenemisvaiheiden sairaalajaksojen määrä kasvoi 10,9 %, mutta hoitopäivien määrä väheni 8,5 %. Ikävakioitujen hoitojaksojen kasvu miehillä oli 0,8 % ja naisilla 18,5 %. Hoitojaksot lisääntyivät yleislääketieteen erikoisalan osastoilla 36,8 % ja keuhkosairauksien osastoilla 17,8 %, kun taas sisätautien osastoilla ne vähenivät 22,3 %. Yleislääkäri lähetti erikoissairaanhoitoon 5,1 % terveyskeskuksen vuodeosastolle otetuista akuuteista KAT:n pahenemisvaiheen potilaista. Yleislääkärin hoitovastuulla olleiden potilaiden ikä- ja sukupuolivakioitu kuoleman riskisuhde oli 0,83 (95 % CI 0,75–0,91) verrattuna keuhkolääkärin vastuulla olleisiin potilaisiin. Perusterveydenhuollossa hoidetuilla potilailla oli 1,74 kertainen riski joutua uudelleen sairaalahoitoon viikon kuluessa KAT:n akuutin pahenemisvaiheen sairaalahoidon jälkeen verrattuna erikoissairaanhoidossa hoidettuihin potilaisiin. 1980-luvun strategiset linjaukset, palvelurakennemuutokset ja kansalliset ohjeet keuhkoahtaumataudin ennaltaehkäisystä ja hoidosta vuodelta 1998 ja Käypä hoito -suositus sekä uudet hoitomuodot ja lääkkeet ovat tehostaneet keuhkoahtaumapotilaan hoitoa. Painopiste on siirtynyt avohoitoon ja perusterveydenhuoltoon, jossa on huolehdittava riittävästä resursoinnista ja koulutuksesta hyvän laadun varmistamiseksi.

Thesis (M.Med. (Paediatrics and Child Health)) -- University of Limpopo, 2021 / Nosocomial infection constitutes a major health problem associated with high morbidity and mortality. This study is aimed at investigating the prevalence of nosocomial infections in paediatric intensive care unit of Pietersburg hospital, Limpopo, South Africa and identify the pathogens responsible for such infections and determine their anti-microbial activity. The study applied a retrospective quantitative descriptive study design to execute the objectives of the study. Convenience sampling was applied to select 98 participants that met the selection criteria to collect the data set from the hospital files between 1st January 2017 to 31st December 2017 in a self-designed template. Results shows that the prevalence of nosocomial infections in children admitted from 1st January 2017–31st December 2017 at Pietersburg hospital was 13.27% where majority were females at 61,5% with the remaining 38,5% being male. Majority of participants that developed HAI were below 24 months of age (69%). Hospital stay was a mean of 23 days. The underlying conditions in participants who developed HAI were mostly HIV in 4 of 13 (31%) and had association with hospital stay (Chi-square = 140,14; pvalue=0,0034). Majority of patients that acquired HAI were admitted for a respiratory condition n=12; (92%) mainly Pneumonia and Bronchiolitis. Potential risks factors for developing HAI were endotracheal intubation, mechanical ventilation; central venous catheter (Chi- square =21,195; p value= 0,0035); Peripheral vascular catheter (Chisquare = 17,106; p-value= 0,0167); urethral catheter (Chi-square = 20,013; p-value= 0,0055) and surgery since admission (Chi-square = 27,649; p-value= 0,0003). There was a strong correlation between hospital stay and mortality rate (r=36%; p- value<0.0001). Klebsiella pneumonia was the most identified pathogen from the respiratory site (50%). Coagulase-negative staph aureus was the most identified organism in the bloodstream. The study found that the development of HAI was associated with increased length of hospital stay and an increased rate of mortality.

Abstract:Aims: Due to large inconsistencies in previous studies, it remains unclear how alcohol use is related to health care utilization. The aim of this study was to examine associations between alcohol drinking status with utilization of outpatient and inpatient health care services in Germany. Methodology: Survey data of the GEDA 2014/2015-EHIS study with n = 23,561 German adults were analyzed (response rate: 27 %). Respondents were categorized as lifetime abstainers, former drinkers, and non-weekly drinkers, as well as weekly low-risk drinkers and risky drinkers. Outpatient services included GP, specialist, and hospital visits; inpatient services included hospital overnight stays in the last 12 months. For both settings, binary logistic regression models were applied, adjusted for possible confounders. Results: For specialist visits, elevated odds were found among former drinkers (odds ratio (OR) = 1.93, 95 % confidence interval (95 % CI) = 1.50-2.49), non-weekly drinkers (OR = 1.24, 95 % CI = 1.05-1.47), weekly low-risk drinkers (OR = 1.39, 95 % CI = 1.17-1.67), and risky drinkers (OR = 1.28, 95 % CI = 1.04-1.57) compared to lifetime abstainers. In contrast, lower odds for inpatient service use were found among non-weekly drinkers (OR = 0.76, 95 % CI = 0.62-0.93), low-risk drinkers (OR = 0.66, 95 % CI = 0.53-0.81), and risky drinkers (OR = 0.65, 95 % CI = 0.51-0.84). No differences were observed for GP and outpatient hospital visits. Conclusions: While the increased odds of consulting a specialist are consistent with higher health care needs among former and current drinkers, the lower use of inpatient care among current drinkers is contrary to known health risks associated with alcohol consumption and evidence from hospitalized populations. The findings also highlight the need to differentiate between lifetime abstainers and former drinkers in their use of health services.

The thesis focuses on the Risk Life Insurance of the Czech insurance market offering coverage just for serious health risks without any investment or savings component. Assessment of the Risk Life Insurance offer is based on the findings of the general and special insurance conditions as well as on the gained draft insurance contracts worked on the model setting. The aim of the thesis is the analysis of the main coverage which is in all cases the life insurance along with the offer of the complementary insurance for case of death, disability, cancer or severe diseases. The emphasis is on the scope of risks coverage and the insurance conditions which are considered to be an insurance event.

Introdução: A falta de sistemas estruturados de custeio nas organizações hospitalares, principalmente filantrópicas, tem dificultado a análise da cobertura dos custos pelo repasse do Sistema Único de Saúde (SUS) aos procedimentos realizados. Objetivo: Identificar a percentagem de cobertura do repasse de verba do SUS para a cirurgia de revascularização miocárdica (CRM), em um hospital filantrópico do município de São Paulo, que possui um sistema de custeio consolidado. Método: Estudo de abordagem quantitativa, transversal e descritiva. Utilizou-se um banco de dados com registro de CRM denominado REVASC, criado pela instituição em 2009 e de inclusão contínua. As informações para a pesquisa foram coletadas de 13 de março a 30 de setembro de 2012. A escolha do período foi devido ao início da inclusão de informações sobre custo e repasse do SUS. A população alvo foi de 1913 pacientes e amostra de 1362 (71,2%). Resultados: O custo total médio da internação por paciente foi de R$16.196,91. A média de repasse pelo SUS foi de R$6.992,91(48,66%), observando-se um déficit de 9.204,00 (51,34%). A média de idade foi de 61,4 anos e 69,9% eram do sexo masculino. A média do tempo de permanência hospitalar (TPH) foi de 11,23 dias, sendo 2,42 dias na terapia intensiva e 8,49 dias no pós-operatório. A maioria dos pacientes (69,5%) apresentou um TPH maior que sete dias, considerada prolongada pela instituição. Ao comparar o Grupo 1 (TPH7dias) e Grupo 2 (TPH>7dias), este apresentou custo, receita, diferença entre custo-receita e diferença percentual significativamente maiores que os pacientes do Grupo1. Ao associar o TPH com fatores de risco houve diferença apenas no Grupo 2 que apresentou maior idade, maior número de diabetes e de insuficiência renal crônica. Em relação às complicações pós-operatórias houve diferença em relação a transfusão sanguínea, fibrilação atrial, sangramento importante, pneumonia, insuficiência renal aguda, infarto agudo do miocárdio perioperatório, hemodiálise, acidente vascular encefálico, ventilação mecânica prolongada e reoperação por sangramento / mediastinite, também com incidência maior no Grupo2. Conclusão: O repasse do SUS cobriu menos da metade do custo total médio da internação em CRM (48,66%). Embora o valor do repasse do SUS tenha aumentado conforme a elevação do custo, esse ressarcimento foi desproporcional ao custo total, resultando numa diferença percentual de receita cada vez mais negativa a cada aumento do custo e da permanência hospitalar. / Introduction: The lack of structured expense systems in hospital organizations, especially when philanthropic, has hindered the analysis of the coverage of costs by transfer of funds from the Unified Healthcare System (SUS) for the procedures performed. Objective: To identify the percentage of coverage of the transfer of funds from SUS for coronary artery bypass surgery (CABG) in a philanthropic hospital that has a consolidated expense system in the municipality of São Paulo. Method: A quantitative, cross-sectional, and descriptive study. A databank containing data with CABG records called REVASC was used, created by the institution in 2009 with ongoing data inclusion. Information for the research was collected from March 13 to September 30, 2012. The choice of that period was due to the start of inclusion of information on costs and the transfer of funds from SUS. The target population was made up of 1913 patients and a sample of 1362 (71.2%). Results: The total mean cost of hospitalization per patient was R$16,196.91. The mean transfer of funds by SUS was R$6,992.91 (48.66%), with a deficit of 9,204.00 (51.34%). The mean age of the subjects was 61.4 years, and 69.9% of them were men. The mean hospital stay (HS) was 11.23 days, in which 2.42 days were in intensive therapy, and 8.49 days in the postoperative unit. Most of the patients (69.5%) had a HS longer than seven days, considered prolonged by the institution. When comparing Group 1 (HS 7 days) and Group 2 (HS >7 days), the latter group showed costs, revenue, difference between cost and revenue, and percentage difference significantly greater than did the patients from Group 1. In associating the HS with risk factors, there was a greater difference only in Group 2, which showed a higher age, and greater number individuals with diabetes and chronic renal failure. As to postoperative complications, there was a difference as to blood transfusion, atrial fibrillation, significant bleeding, pneumonia, acute renal failure, perioperative acute myocardial infarct, hemodialysis, cerebrovascular accident, prolonged mechanical ventilation, and reoperation due to bleeding/mediastinitis, also with an incidence greater than in Group 2. Conclusion: The financial provision from SUS covered less than half the total mean cost of hospitalization for CABG (48.66%). Although the value transferred from SUS increased according to cost elevation, this reimbursement was disproportional to the total cost, resulting in an increasingly negative percentage difference of revenue for each increase in cost and in hospital stay.
