¿Cuánta carga asistencial suponen las dermatosis pediátricas en la actividad ambulatoria en la dermatología española? Resultados del muestreo aleatorio nacional DIADERM / What Proportion of the Spanish Dermatology Caseload Corresponds to Pediatric Dermatoses? Results From the DIADERM National Random Sampling Survey

Introducción Los motivos de consulta de índole dermatológico son muy frecuentes en las consultas de pediatría de atención primaria, e igualmente muchos de los pacientes atendidos en consultas de dermatología son niños y adolescentes. A pesar de ello, faltan estudios sobre la prevalencia real de estas consultas y sus características. Material y método Estudio observacional de corte transversal de 2 períodos de tiempo describiendo los diagnósticos realizados en consultas externas dermatológicas, obtenidos a través de la encuesta anónima DIADERM, realizada a una muestra aleatoria y representativa de dermatólogos. A partir de la codificación de diagnósticos CIE-10, se seleccionaron todos los diagnósticos codificados en los menores de 18 años (84 diagnósticos codificados en los 2 períodos), que se agruparon en 14 categorías diagnósticas relacionadas para facilitar su análisis y comparación. Resultados Un total de 20.097 diagnósticos fueron efectuados en pacientes menores de 18 años, lo que supone un 12% del total de los codificados en DIADERM. Las infecciones víricas, el acné y la dermatitis atópica fueron los diagnósticos más comunes (43,9% de todos los diagnósticos). No se observaron diferencias estadísticamente significativas en la proporción de diagnósticos atendidos en las consultas monográficas frente a las generales, así como en los registrados en el ámbito público frente al privado. Tampoco las hubo en los diagnósticos en función de la época de la encuesta (enero y mayo). Conclusiones La atención a pacientes pediátricos por parte de dermatólogos en España supone una proporción significativa de la actividad habitual.

Background Visits for skin conditions are very common in pediatric primary care, and many of the patients seen in outpatient dermatology clinics are children or adolescents. Little, however, has been published about the true prevalence of these visits or about their characteristics. Material and methods Observational cross-sectional study of diagnoses made in outpatient dermatology clinics during 2 data-collection periods in the anonymous DIADERM National Random Survey of dermatologists across Spain. All entries with an International Classification of Diseases, Tenth Revision code related to dermatology in the 2 periods (84 diagnoses) were collected for patients younger than 18 years and classified into 14 categories to facilitate analysis and comparison. Results In total, the search found 20 097 diagnoses made in patients younger than 18 years (12% of all coded diagnoses in the DIADERM database). Viral infections, acne, and atopic dermatitis were the most common, accounting for 43.9% of all diagnoses. No significant differences were observed in the proportions of diagnoses in the respective caseloads of specialist vs. general dermatology clinics or public vs. private clinics. Seasonal differences in diagnoses (January vs. May) were also nonsignificant. Conclusions Pediatric care accounts for a significant proportion of the dermatologist's caseload in Spain. Our findings are useful for identifying opportunities for improving communication and training in pediatric primary care and for designing training focused on the optimal treatment of acne and pigmented lesions (with instruction on basic dermoscopy use) in these settings (AU)

Lessons learned from value-based pediatric appendectomy care: A shared savings pilot model.

PURPOSE: We aim to assess the healthcare value achieved from a shared savings program for pediatric appendectomy. METHODS: All appendectomy patients covered by our health plan were included. Quality targets were 15% reduction in time to surgery, length of stay, readmission rate, and patient satisfaction. Quality targets and costs for an appendectomy episode in two 6-month performance periods (PP1, PP2) were compared to baseline. RESULTS: 640 patients were included (baseline:317, PP1:167, PP2:156). No quality targets were met in PP1. Two quality targets were met during PP2: readmission rate (-57%) and patient satisfaction. No savings were realized because the cost reduction threshold (-9%) was not met during PP1 (+1.7%) or PP2 (-0.4%). CONCLUSIONS: Payer-provider partnerships can be a platform for testing value-based reimbursement models. Setting achievable targets, identifying affectable quality metrics, considering case mix index, and allowing sufficient time for interventions to generate cost savings should be considered in future programs.

Association of the All-Patient Refined Diagnosis-Related Groups Severity of Illness and Risk of Mortality Classification with Outcomes.

OBJECTIVES: Diagnosis-related groups (DRGs) is a patient classification system used to characterize the types of patients that the hospital manages and to compare the resources needed during hospitalization. The DRG classification is based on International Classification of Diseases diagnoses, procedures, demographics, discharge status, and complications or comorbidities and compares hospital resources and outcomes used to determine how much Medicare pays the hospital for each "product/medical condition." The All-Patient Refined DRG (APR-DRG) incorporated severity of illness (SOI) and risk of mortality (ROM) into the DRG system to adjust for patient complexity to compare resource utilization, complication rates, and lengths of stay. METHODS: This study included 18,478 adult patients admitted to a tertiary care center in Lubbock, Texas during a 1-year period. We recorded the APR-DRG SOI and ROM and some clinical information on these patients, including age, sex, admission shock index, admission glucose and lactate levels, diagnoses based on International Classification of Diseases, Tenth Revision discharge coding, length of stay, and mortality. We compared the levels of SOI and ROM across this clinical information. RESULTS: As the levels of SOI and ROM increase (which indicates increased disease severity and risk of mortality), age, glucose levels, lactate levels, shock index, length of stay, and mortality increased significantly (P < 0.001). Multiple logistic regression analysis demonstrated that each unit increase in ROM and SOI level was significantly associated with an 11.45 and a 10.37 times increase in the odds of in-hospital mortality, respectively. The C-statistics for the corresponding models are 0.947 and 0.929, respectively. When both ROM and SOI were included in the model, the magnitudes of increase in odds of in-hospital mortality were 5.61 and 1.17 times for ROM and SOI, respectively. The C-statistic is 0.949. CONCLUSIONS: This study indicates that the APR-DRG SOI and ROM scores provide a classification system that is associated with mortality and correlates with other clinical variables, such as the shock index and lactate levels, which are available on admission.

Quality of Care Before and After Mergers and Acquisitions of Rural Hospitals.

Importance: Rural hospitals are increasingly merging with other hospitals. The associations of hospital mergers with quality of care need further investigation. Objectives: To examine changes in quality of care for patients at rural hospitals that merged compared with those that remained independent. Design, Setting, and Participants: In this case-control study, mergers at community nonrehabilitation hospitals in Federal Office of Rural Health Policy-eligible zip codes during 2009 to 2016 in 32 states were identified from Irving Levin Associates and the American Hospital Association Annual Survey. Outcomes for inpatient stays for select conditions and elective procedures were derived from the Healthcare Cost and Utilization Project State Inpatient Databases. Difference-in-differences linear probability models were used to assess premerger to postmerger changes in outcomes for patients discharged from merged vs comparison hospitals that remained independent. Data were analyzed from February to December 2020. Exposures: Hospital mergers. Main Outcomes and Measures: The main outcome was in-hospital mortality among patients admitted for acute myocardial infarction (AMI), heart failure, stroke, gastrointestinal hemorrhage, hip fracture, or pneumonia, as well as complications during stays for elective surgeries. Results: A total of 172 merged hospitals and 266 comparison hospitals were analyzed. After matching, baseline patient characteristics were similar for 303 747 medical stays and 175 970 surgical stays at merged hospitals and 461 092 medical stays and 278 070 surgical stays at comparison hospitals. In-hospital mortality among AMI stays decreased from premerger to postmerger at merged hospitals (9.4% to 5.0%) and comparison hospitals (7.9% to 6.3%). Adjusting for patient, hospital, and community characteristics, the decrease in in-hospital mortality among AMI stays 1 year postmerger was 1.755 (95% CI, -2.825 to -0.685) percentage points greater at merged hospitals than at comparison hospitals (P < .001). This finding held up to 4 years postmerger (DID, -2.039 [95% CI, -3.388 to -0.691] percentage points; P = .003). Greater premerger to postmerger decreases in mortality at merged vs comparison hospitals were also observed at 5 years postmerger among stays for heart failure (DID, -0.756 [95% CI, -1.448 to -0.064] percentage points; P = .03), stroke (DID, -1.667 [95% CI, -3.050 to -0.283] percentage points; P = .02), and pneumonia (DID, -0.862 [95% CI, -1.681 to -0.042] percentage points; P = .04). Conclusions and Relevance: These findings suggest that rural hospital mergers were associated with better mortality outcomes for AMI and several other conditions. This finding is important to enhancing rural health care and reducing urban-rural disparities in quality of care.

A Simple Approach to Adjust for Case-Mix When Comparing Institutional Cesarean Birth Rates.

OBJECTIVE: This study aimed to develop a validated model to predict intrapartum cesarean in nulliparous women and to use it to adjust for case-mix when comparing institutional laboring cesarean birth (CB) rates. STUDY DESIGN: This multicenter retrospective study used chart-abstracted data on nulliparous, singleton, term births over a 7-year period. Prelabor cesareans were excluded. Logistic regression was used to predict the probability of CB for individual pregnancies. Thirty-five potential predictive variables were evaluated including maternal demographics, prepregnancy health, pregnancy characteristics, and newborn weight and gender. Models were trained on 21,017 births during 2011 to 2015 (training cohort), and accuracy assessed by prediction on 15,045 births during 2016 to 2017 (test cohort). RESULTS: Six variables delivered predictive success equivalent to the full set of 35 variables: maternal weight, height, and age, gestation at birth, medically-indicated induction, and birth weight. Internal validation within the training cohort gave a receiver operator curve with area under the curve (ROC-AUC) of 0.722. External validation using the test cohort gave ROC-AUC of 0.722 (0.713-0.731 confidence interval). When comparing observed and predicted CB rates at 16 institutions in the test cohort, five had significantly lower than predicted rates and three had significantly higher than predicted rates. CONCLUSION: Six routine clinical variables used to adjust for case-mix can identify outliers when comparing institutional CB rates.

Tracheotomy Timing and Outcomes in the Critically Ill: Complexity and Opportunities for Progress.

OBJECTIVES/HYPOTHESIS: To characterize the effects of tracheotomy timing at our institution on intensive care unit (ICU) length of stay (LOS) and overall hospital LOS. STUDY DESIGN: Retrospective cohort study. METHODS: A retrospective study was performed at a tertiary care medical center for patients undergoing tracheotomy over 2.5 years from January 1, 2016 through June 30, 2018. Demographics, survival, duration of endotracheal intubation, timing of tracheotomy, and ICU and overall hospital LOS were assessed. Tracheotomy was considered early (ET) if it was performed by day 7 of mechanical ventilation and late (LT) thereafter. Readmission, mortality, and costs were also tabulated for each aggregate group. Nonparametric statistics were used to compare results. RESULTS: Of the 536 patients included in the analysis, 160 received tracheotomy early and 376 late. Differences between age and sex were not statistically significant. Duration of total ICU stay was shortened by 65% (12.84 ± 17.69 days vs. 38.49 ± 26.61 days; P < .0001), and length of overall hospital course was reduced by 54% (22.71 ± 26.65 days vs. 50.37 ± 34.20 days; P < .0001) in the early tracheotomy group. Observed/expected (O/E) values standardized results to case mix index and revealed LOS of 1.5 for ET and 2.5 for LT, and mortality of 0.76 for ET and 1.25 for LT, and comparable readmissions of both groups. CONCLUSIONS: Early tracheotomy in ICU patients is associated with earlier ICU discharge, decreased length of overall hospital stay, and lower mortality when controlling for case mix index. Opportunities exist to optimize patient outcomes and O/E performance. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:282-287, 2021.

Decreased hospital admissions through emergency departments during the COVID-19 pandemic.

STUDY OBJECTIVE: Emergency Department (ED) visits decreased significantly in the United States during the COVID-19 pandemic. A troubling proportion of this decrease was among patients who typically would have been admitted to the hospital, suggesting substantial deferment of care. We sought to describe and characterize the impact of COVID-19 on hospital admissions through EDs, with a specific focus on diagnosis group, age, gender, and insurance coverage. METHODS: We conducted a retrospective, observational study of aggregated third-party, anonymized ED patient data. This data included 501,369 patient visits from twelve EDs in Massachusetts from 1/1/2019-9/9/2019, and 1/1/2020-9/8/2020. We analyzed the total arrivals and hospital admissions and calculated confidence intervals for the change in admissions for each characteristic. We then developed a Poisson regression model to estimate the relative contribution of each characteristic to the decrease in admissions after the statewide lockdown, corresponding to weeks 11 through 36 (3/11/2020-9/8/2020). RESULTS: We observed a 32% decrease in admissions during weeks 11 to 36 in 2020, with significant decreases in admissions for chronic respiratory conditions and non-orthopedic needs. Decreases were particularly acute among women and children, as well as patients with Medicare or without insurance. The most common diagnosis during this time was SARS-CoV-2. CONCLUSION: Our findings demonstrate decreased hospital admissions through EDs during the pandemic and suggest that several patient populations may have deferred necessary care. Further research is needed to determine the clinical and operational consequences of this delay.

Predictive value of indicators for identifying child maltreatment and intimate partner violence in coded electronic health records: a systematic review and meta-analysis.

OBJECTIVE: Electronic health records (EHRs) are routinely used to identify family violence, yet reliable evidence of their validity remains limited. We conducted a systematic review and meta-analysis to evaluate the positive predictive values (PPVs) of coded indicators in EHRs for identifying intimate partner violence (IPV) and child maltreatment (CM), including prenatal neglect. METHODS: We searched 18 electronic databases between January 1980 and May 2020 for studies comparing any coded indicator of IPV or CM including prenatal neglect defined as neonatal abstinence syndrome (NAS) or fetal alcohol syndrome (FAS), against an independent reference standard. We pooled PPVs for each indicator using random effects meta-analyses. RESULTS: We included 88 studies (3 875 183 individuals) involving 15 indicators for identifying CM in the prenatal period and childhood (0-18 years) and five indicators for IPV among women of reproductive age (12-50 years). Based on the International Classification of Disease system, the pooled PPV was over 80% for NAS (16 studies) but lower for FAS (<40%; seven studies). For young children, primary diagnoses of CM, specific injury presentations (eg, rib fractures and retinal haemorrhages) and assaults showed a high PPV for CM (pooled PPVs: 55.9%-87.8%). Indicators of IPV in women had a high PPV, with primary diagnoses correctly identifying IPV in >85% of cases. CONCLUSIONS: Coded indicators in EHRs have a high likelihood of correctly classifying types of CM and IPV across the life course, providing a useful tool for assessment, support and monitoring of high-risk groups in health services and research.

Estudio del impacto de la pandemia por COVID-19 en las Urgencias Pediátricas de un hospital de tercer nivel / Study on the impact of COVID-19 pandemic on pediatric emergencies of a third level hospital

Introducción. En los últimos años, los servicios de urgencias hospitalarias han experimentado un aumento progresivo de la demanda asistencial, a expensas de patología banal. Esta tendencia cambia a partir del 14 de marzo, cuando se decreta el estado de alarma debido a la pandemia por COVID-19, lo que supone el confinamiento obligatorio poblacional. Objetivos. Determinar el impacto que este estado de alarma ha tenido en el volumen de las urgencias pediátricas de un hospital de tercer nivel. Material y métodos. Se ha realizado un estudio retrospectivo de cohortes y se han incluido los menores de 14 años que demandaron asistencia durante los meses del estado de alarma y durante los mismos meses en el año anterior. Se han analizado diferentes datos epidemiológicos y clínicos. Resultados. 3.371 pacientes acudieron a nuestro Servicio de Urgencias en 2019 y 650 lo hicieron en 2020, siendo la media de edad de los pacientes similar. Los grupos diagnósticos al alta más frecuentes en ambos periodos de tiempo fueron las patologías infecciosa y digestiva. En cuanto a los ingresos hospitalarios, en 2019 requirieron ingreso el 7,12%, y en 2020, el 13,69%. Respecto al servicio a cargo del paciente durante el ingreso, destaca que en 2020 el 27,72% lo hizo a cargo de Cirugía Pediátrica. Conclusiones. La actividad en las Urgencias Pediátricas de nuestro hospital ha variado notablemente durante el estado de alarma. Se ha producido una disminución considerable del número de pacientes que han demandado asistencia debido a la percepción de riesgo de contagio por parte de la población. Además, hemos percibido un aumento relativo de los ingresos hospitalarios y, en concreto, en la patología quirúrgica urgente con respecto al año anterior (AU)

Objectives. In recent years, hospital emergency departments have experienced a progressive increase in the demand for care, at the expense of trivial pathology. This trend changes from 14 March 2020, when the state of alarm was declared due to the COVID-19 pandemic, which led to the compulsory confinement of the population. The main objective of this study was to determine the impact that this state of alarm has had on the volume of paediatric emergencies in a third level hospital. Material and methods. A retrospective study of cohorts was carried out and included those under 14 years of age who demanded care during the months of the state of alarm and during the same months in the previous year. Different epidemiological and clinical data have been analysed. Results. 3,371 patients attended our Emergency Department in 2019, and 650 in 2020, with a similar average patient age. The most frequent diagnostic groups at discharge in both time periods were infectious and digestive diseases. In terms of hospital admissions, 7.12% required admission in 2019 and 13.69% in 2020. Regarding the department in charge of the patient during admission, in 2020 27.72% of patients were admitted by Paediatric Surgery. Conclusions. The activity in the paediatric emergency departments of our hospital varied considerably during the state of alarm. There has been a considerable decrease in the number of patients who have requested assistance due to the perceived risk of contagion by the population. In addition, we have perceived a relative increase in hospital admissions and, specifically, in urgent surgical pathology compared to the previous year (AU)

El 34,6% están publicados en inglés, el 45,8% están basados en casuística de usuarios atendidos, y la temática más frecuente es la psicología y salud mental (58,1%). Los 75 artículos de revistas incluidas en el SCI han recibido 1.252 citas, y los 152 artículos incluidos en Google Scholar, 3.105 citas. La mayor media de citas SCI por artículo corresponde a los publicados en inglés (22,2), basados en casuística (21,1), ámbito de la neuroimagen (52), y generados desde la UIG de Cataluña (25,7). CONCLUSIONES: La producción científica española sobre disforia de género generada desde las UIG ha tenido un cre-cimiento progresivo, abarca una amplia temática, incluye un elevado número de estudios basados en el análisis de la casuística de la población atendida, y las citaciones recibidas reflejan un impacto en la comunidad científica y un liderazgo internacional en algunas áreas como la neuroimagen

OBJECTIVE: To provide a bibliometric and contents analyses of the Spanish research in the field of gender dysphoria based on a literature review. METHOD: Five international and four national databases, and two platforms were used to retrieve publications using the keyword "gender dysphoria" and related terms. The results were combined with Spain and with the name of the Spanish cities' names with a hospital. The articles published from the Gender Identity Units (GIU) being part of the National Health System were selected. The number of citations was assessed using the Science Citation Index (SCI) and Google Scholar. RESULTS: A total of 179 articles were included. Production shows a progressive increase from 1999 to 2015 and a slight de-crease in the following years. 34.6% were published in English, 45.8% were based on set of cases, and the most frequent topic is psychology and mental health (58.1%). The 75 publications indexed in the SCI had received 1,252 citations, and the 152 found in Google Scholar reached 3,105 citations. The highest SCI average citation per article corresponds to those published in English (22.2), based on set of cases (21.1), in the field of neuroimaging (52), and coming from the Catalonia GIU (25.7). CONCLUSIONS: The Spanish research on gender dysphoria produced from the GIUs has had a progressive growth, covers many topics, includes a high number of studies based on set of cases, and the number of citations reflect an impact on the scientific community and international leadership in some areas such as neuroimaging

DRG-Oriented Mathematical Calculation Model and Method of Integrated Medical Service Cost.

In the context of the new round of medical and health reform, in order to alleviate the problem of "difficult to see a doctor and expensive to see a doctor," the state focuses on reducing the cost of medical services, so it puts forward the calculation and method research of medical costs. The purpose of this study is to calculate and predict the cost of medical services in a DRG-oriented integrated environment. In this study, activity-based costing and weighted moving average methods are used. First, basic data of medical services are collected, then all medical activities are confirmed and all service costs are collected, then a cost database is established, and a calculation model of medical costs is designed. Finally, calculation suggestions and optimization methods are put forward by analyzing the calculated data. The experimental results show that the actual demand of drugs predicted by the general moving average method is relatively insufficient, with the maximum error of 41%, the minimum of 5%, and the average error of 19.8%; the maximum error of drug demand predicted by the weighted moving average method is 24%, the minimum is 2%, and the average is 15.4%. It can be concluded that the prediction effect of the weighted moving average method is better than that of the ordinary moving average method, which plays a good and effective role in the prediction of medical cost. The activity-based costing method is more detailed and organized for the cost calculation and classification of medical services. It provides a certain value for the effective management and control of medical service cost.

[Influence of a spontaneous bacterial peritonitis, nosocomial infections and acute-on-chronic liver failure on treatment revenues in patients with decompensated cirrhosis in Germany]. / Einfluss einer spontan bakteriellen Peritonitis, nosokomialer Infektionen und eines akut auf chronischen Leberversagens auf die Behandlungserlöse bei Patienten mit dekompensierter Leberzirrhose in Deutschland.

BACKGROUND: The economic effects of spontaneous bacterial peritonitis (SBP), nosocomial infections (nosInf) and acute-on-chronic liver failure (ACLF) have so far been poorly studied. We analyzed the impact of these complications on treatment revenues in hospitalized patients with decompensated cirrhosis. METHODS: 371 consecutive patients with decompensated liver cirrhosis, who received a paracentesis between 2012 and 2016, were included retrospectively. DRG (diagnosis-related group), "ZE/NUB" (additional charges/new examination/treatment methods), medication costs, length of hospital stay as well as different kinds of specific treatments (e. g., dialysis) were considered. Exclusion criteria included any kind of malignancy, a history of organ transplantation and/or missing accounting data. RESULTS: Total treatment costs (DRG + ZE/NUB) were higher in those with nosInf (€â€Š10,653 vs. €â€Š5,611, p < 0.0001) driven by a longer hospital stay (23 d vs. 12 d, p < 0.0001). Of note, revenues per day were not different (€â€Š473 vs. €â€Š488, p = 0.98) despite a far more complicated treatment with a more frequent need for dialysis (p < 0.0001) and high-complex care (p = 0.0002). Similarly, SBP was associated with higher total revenues (€â€Š10,307 vs. €â€Š6,659, p < 0.0001). However, the far higher effort for the care of SBP patients resulted in lower daily revenues compared to patients without SBP (€â€Š443 vs. €â€Š499, p = 0.18). ACLF increased treatment revenues to €â€Š10,593 vs. €6,369 without ACLF (p < 0.0001). While treatment of ACLF was more complicated, revenue per day was not different to no-ACLF patients (€â€Š483 vs. €â€Š480, p = 0.29). CONCLUSION: SBP, nosInf and/or ACLF lead to a significant increase in the effort, revenue and duration in the treatment of patients with cirrhosis. The lower daily revenue, despite a much more complex therapy, might indicate that these complications are not yet sufficiently considered in the German DRG system.

Self-reported symptoms among participants in a population-based screening program.

BACKGROUND: A limited number of studies have explored the association between self-reported symptoms and the risk of breast cancer among participants of population based screening programs. METHODS: We performed descriptive statistics on recall, screen-detected and interval cancer, positive predictive value and histopathological tumour characteristics by symptom group (asymptomatic, lump, and skin or nipple changes) as reported from 785,642 women aged 50-69 when they attended BreastScreen Norway 1996-2016. Uni- and multivariable mixed effects logistic regression models were used to analyze the association between symptom group and screen-detected or interval cancer. Results were presented as odds ratios and 95% confidence intervals (CI). RESULTS: A lump or skin/nipple change was reported in 6.2% of the 3,307,697 examinations. The rate of screen-detected cancers per 1000 examinations was 45.2 among women with a self-reported lump and 5.1 among asymptomatic women. Adjusted odds ratio of screen-detected cancer was 10.1 (95% CI: 9.3-11.1) and 2.0 (95% CI: 1.6-2.5) for interval cancer among women with a self-reported lump versus asymptomatic women. Tumour diameter, histologic grade and lymph node involvement of screen-detected and interval cancer were less prognostically favourable for women with a self-reported lump versus asymptomatic women. CONCLUSION: Despite targeting asymptomatic women, 6.2% of the screening examinations in BreastScreen Norway was performed among women who reported a lump or skin/nipple change when they attended screening. The odds ratio of screen-detected cancer was higher for women with versus without symptoms. Standardized follow-up guidelines might be beneficial for screening programs in order to take care of women reporting signs or symptoms of breast cancer when they attend screening.

What presents to a rural district emergency department: A case mix.

BACKGROUND: There is little information available on the range of conditions presenting to generalist run rural district hospital emergency departments (EDs) which are the first point of acute care for many South Africans. AIM: This study aims to assess the range of acute presentations as well as the types of procedures required by patients in a rural district hospital context. SETTING: Zithulele is a 147-bed district hospital in rural Eastern Cape. METHODS: This is a cross-sectional study assessing all patients presenting to the Zithulele hospital emergency department from 01 October 2015 to 31 December 2015. Data collected included the triage acuity using the South African Triage Scale system, patient demographics, diagnosis, outcome and procedures performed. Diagnoses were coded retrospectively according to the international statistical classification of diseases and related health problems version 10 (ICD 10). RESULTS: Of the 4 002 patients presenting to the ED during the study period, 2% were triaged as emergencies and 45% as non-urgent. The most common diagnostic categories were injuries, infections and respiratory illnesses respectively. Diagnoses from all broad categories of the ICD-10 were represented. 67% of patients required no procedure. Diagnostic procedures (n = 877) were more prevalent than therapeutic procedures (n = 377). Only 2.4% of patients were transferred to a referral centre acutely. CONCLUSION: Patients with conditions from all categories of the ICD-10 present for management at rural district hospitals. Healthcare professionals working in this setting need to independently diagnose and manage a wide range of ED presentations and execute an assortment of procedures.

Comparison of individual and neighbourhood socioeconomic status in case mix adjustment of hospital performance in primary total hip replacement in Sweden: a register-based study.

BACKGROUND: Case mix adjustment is a pre-requisite for valid measurement of healthcare performance and socioeconomic status (SES) is important to account for. Lack of information on individual-level SES has led to investigations into using a proxy for SES based on patient area of residence. The objective of this study was to use neighbourhood SES for case mix adjustment of performance indicators in total hip replacement (THR) in Sweden, and to compare with use of individual SES. METHODS: Data from patient administrative systems and the Swedish Hip Arthroplasty Register were extracted for all patients undergoing THR in four Swedish regions. For each subject, individual data and neighbourhood data on country of birth, educational level, and income were provided by Statistics Sweden. Three variables were selected for analysis of performance; EQ-5D, hip pain and length of stay (LoS). In addition to socioeconomic information, several important clinical characteristics were used as case mix factors. Regression analysis was used to study each variable's impact on the three outcome variables and model fit was evaluated using mean squared error. RESULTS: A total of 27,121 patients operated between 2010 and 2016 were included in the study. Both educational level and income were higher when based on neighbourhood information than individual information, while proportion born in Sweden was similar. Higher SES was generally found to be associated with better outcomes and lower LoS, albeit with certain differences between the different measures of SES. The predictive ability of the models was increased when adding information on SES to the clinical characteristics. The increase in predictive ability was higher for individual SES compared to neighbourhood SES. When analysing performance for the two providers with most diverging case mix in terms of SES, the inclusion of SES altered the relative performance using individual as well as neighbourhood SES. CONCLUSIONS: Incorporating SES improves case mix adjustment marginally compared to using only clinical information. In this patient group, geographically derived SES was found to improve case mix adjustment compared to only clinical information but not to the same extent as actual individual-level SES.

Association of Do-Not-Resuscitate Patient Case Mix With Publicly Reported Risk-Standardized Hospital Mortality and Readmission Rates.

Importance: The Centers for Medicare and Medicaid Services's (CMS's) 30-day risk-standardized mortality rate (RSMR) and risk-standardized readmission rate (RSRR) models do not adjust for do-not-resuscitate (DNR) status of hospitalized patients and may bias Hospital Readmissions Reduction Program (HRRP) financial penalties and Overall Hospital Quality Star Ratings. Objective: To identify the association between hospital-level DNR prevalence and condition-specific 30-day RSMR and RSRR and the implications of this association for HRRP financial penalty. Design, Setting, and Participants: This cross-sectional study obtained patient-level data from the Medicare Limited Data Set Inpatient Standard Analytical File and hospital-level data from the CMS Hospital Compare website for all consecutive Medicare inpatient encounters from July 1, 2015, to June 30, 2018, in 4484 US hospitals. Hospitalized patients had a principal diagnosis of acute myocardial infarction (AMI), heart failure (HF), stroke, pneumonia, or chronic obstructive pulmonary disease (COPD). Incoming acute care transfers, discharges against medical advice, and patients coming from or discharged to hospice were among those excluded from the analysis. Exposures: Present-on-admission (POA) DNR status was defined as an International Classification of Diseases, Ninth Revision diagnosis code of V49.86 (before October 1, 2015) or as an International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnosis code of Z66 (beginning October 1, 2015). Hospital-level prevalence of POA DNR status was calculated for each of the 5 conditions. Main Outcomes and Measures: Hospital-level 30-day RSMRs and RSRRs for 5 condition-specific cohorts (mortality cohorts: AMI, HF, stroke, pneumonia, and COPD; readmission cohorts: AMI, HF, pneumonia, and COPD) and HRRP financial penalty status (yes or no). Results: Included in the study were 4 884 237 inpatient encounters across condition-specific 30-day mortality cohorts (patient mean [SD] age, 78.8 [8.5] years; 2 608 182 women [53.4%]) and 4 450 378 inpatient encounters across condition-specific 30-day readmission cohorts (patient mean [SD] age, 78.6 [8.5] years; 2 349 799 women [52.8%]). Hospital-level median (interquartile range [IQR]) prevalence of POA DNR status in the mortality cohorts varied: 11% (7%-16%) for AMI, 13% (7%-23%) for HF, 14% (9%-22%) for stroke, 17% (9%-26%) for pneumonia, and 10% (5%-18%) for COPD. For the readmission cohorts, the hospital-level median (IQR) POA DNR prevalence was 9% (6%-15%) for AMI, 12% (6%-22%) for HF, 16% (8%-24%) for pneumonia, and 9% (4%-17%) for COPD. The 30-day RSMRs were significantly higher for hospitals in the highest quintiles vs the lowest quintiles of DNR prevalence (eg, AMI: 12.9 [95% CI, 12.8-13.1] vs 12.5 [95% CI, 12.4-12.7]; P < .001). The inverse was true among the readmission cohorts, with the highest quintiles of DNR prevalence exhibiting the lowest RSRRs (eg, AMI: 15.3 [95% CI, 15.1-15.5] vs 15.9 [95% CI, 15.7-16.0]; P < .001). A 1% absolute increase in risk-adjusted hospital-level DNR prevalence was associated with greater odds of avoiding HRRP financial penalty (odds ratio, 1.06; 95% CI, 1.04-1.08; P < .001). Conclusions and Relevance: This cross-sectional study found that the lack of adjustment in CMS 30-day RSMR and RSRR models for POA DNR status of hospitalized patients may be associated with biased readmission penalization and hospital-level performance.

Assessing the Impacts of Misclassified Case-Mix Factors on Health Care Provider Profiling: Performance of Dialysis Facilities.

Quantitative metrics are used to develop profiles of health care institutions, including hospitals, nursing homes, and dialysis clinics. These profiles serve as measures of quality of care, which are used to compare institutions and determine reimbursement, as a part of a national effort led by the Center for Medicare and Medicaid Services in the United States. However, there is some concern about how misclassification in case-mix factors, which are typically accounted for in profiling, impacts results. We evaluated the potential effect of misclassification on profiling results, using 20 744 patients from 2740 dialysis facilities in the US Renal Data System. In this case study, we compared 30-day readmission as the profiling outcome measure, using comorbidity data from either the Center for Medicare and Medicaid Services Medical Evidence Report (error-prone) or Medicare claims (more accurate). Although the regression coefficient of the error-prone covariate demonstrated notable bias in simulation, the outcome measure-standardized readmission ratio-and profiling results were quite robust; for example, correlation coefficient of 0.99 in standardized readmission ratio estimates. Thus, we conclude that misclassification on case-mix did not meaningfully impact overall profiling results. We also identified both extreme degree of case-mix factor misclassification and magnitude of between-provider variability as 2 factors that can potentially exert enough influence on profile status to move a clinic from one performance category to another (eg, normal to worse performer).
