Use of Hospital-Based Acute Care Among Patients Recently Discharged From the Hospital

IMPORTANCE Current efforts to improve health care focus on hospital readmission rates as a marker of quality and on the effectiveness of transitions in care during the period after acute care is received. Emergency department (ED) visits are also a marker of hospital-based acute care following discharge but little is known about ED use during this period. OBJECTIVES To determine the degree to which ED visits and hospital readmissions contribute to overall use of acute care services within 30 days of discharge from acute care hospitals, to describe the reasons patients return for ED visits, and to describe these patterns among Medicare beneficiaries and those not covered by Medicare insurance. DESIGN, SETTING, AND PARTICIPANTS Prospective study of patients aged 18 years or older (mean age: 53.4 years) who were discharged between July 1, 2008, and September 31, 2009, from acute care hospitals in 3 large, geographically diverse states (California, Florida, and Nebraska) with data recorded in the Healthcare Cost and Utilization Project state inpatient and ED databases. MAIN OUTCOME MEASURES The 3 primary outcomes during the 30-day period after hospital discharge were ED visits not resulting in admission (treat-and-release encounters), hospital readmissions from any source, and a combined measure of ED visits and hospital readmissions termed hospital-based acute care. RESULTS The final cohort included 5,032,254 index hospitalizations among 4,028,555 unique patients. In the 30 days following discharge, 17.9% (95% CI, 17.9%-18.0%) of hospitalizations resulted in at least 1 acute care encounter. Of these 1,233,402 postdischarge acute care encounters, ED visits comprised 39.8% (95% CI, 39.7%-39.9%). For every 1000 discharges, there were 97.5 (95% CI, 97.2-97.8) ED treat-and-release visits and 147.6 (95% CI, 147.3-147.9) hospital readmissions in the 30 days following discharge. The number of ED treat-and-release visits ranged from a low of 22.4 (95% CI, 4.6-65.4) encounters per 1000 discharges for breast malignancy to a high of 282.5 (95% CI, 209.7-372.4) encounters per 1000 discharges for uncomplicated benign prostatic hypertrophy. Among the highest volume discharges, the most common reason patients returned to the ED was always related to their index hospitalization. CONCLUSIONS AND RELEVANCE After discharge from acute care hospitals in 3 states, ED visits within 30 days were common among adults and accounted for 39.8% of postdischarge hospital-based acute care visits. Improving care transitions should focus not only on decreasing readmissions but also on ED visits.

Review article: Convulsive and non‐convulsive status epilepticus: An emergency medicine perspective

Status epilepticus (SE) is divided into convulsive and non‐convulsive types; both are associated with significant morbidity and mortality. Although convulsive SE is easily recognized, non‐convulsive SE remains an elusive diagnosis as physical signs are varied and subtle. Successful management depends on a comprehensive approach that involves diagnostic testing and pharmacological interventions while ensuring cerebral oxygenation and perfusion at all times. There are a limited number of well‐designed studies to support the development of evidence‐based recommendations for the management of SE, especially for the management of non‐convulsive status. Benzodiazepines, specifically lorazepam, continue to be the most commonly recommended first‐line therapy; best treatment for refractory status cases depends on resources available and must be tailored to the individual institution. In order to facilitate care, it is recommended that each institution develop a management protocol for these patients.

Hospital-based, acute care after ambulatory surgery center discharge.

BACKGROUND As a measure of quality, ambulatory surgery centers have begun reporting rates of hospital transfer at discharge. This process, however, may underestimate the acute care needs of patients after care. We conducted this study to determine rates and evaluate variation in hospital transfer and hospital-based, acute care within 7 days among patients discharged from ambulatory surgery centers. METHODS Using data from the Healthcare Cost and Utilization Project, we identified adult patients who underwent a medical or operative procedure between July 2008 and September 2009 at ambulatory surgery centers in California, Florida, and Nebraska. The primary outcomes were hospital transfer at the time of discharge and hospital-based, acute care (emergency department visits or hospital admissions) within 7-days expressed as the rate per 1,000 discharges. At the ambulatory surgery center level, rates were adjusted for age, sex, and procedure-mix. RESULTS We studied 3,821,670 patients treated at 1,295 ambulatory surgery centers. At discharge, the hospital transfer rate was 1.1 per 1,000 discharges (95% confidence interval 1.1-1.1). Among patients discharged home, the hospital-based, acute care rate was 31.8 per 1,000 discharges (95% confidence interval 31.6-32.0). Across ambulatory surgery centers, there was little variation in adjusted hospital transfer rates (median = 1.0/1,000 discharges [25th-75th percentile = 1.0-2.0]), whereas substantial variation existed in adjusted, hospital-based, acute care rates (28.0/1,000 [21.0-39.0]). CONCLUSION Among adult patients undergoing ambulatory care at surgery centers, hospital transfer at time of discharge from the ambulatory care center is a rare event. In contrast, the rate of need for hospital-based, acute care in the first week afterwards is nearly 30-fold greater, varies across centers, and may be a more meaningful measure for discriminating quality.

Navigating the Boundaries of Emergency Department Care: Addressing the Medical and Social Needs of Patients Who Are Homeless

OBJECTIVES We sought to understand interpersonal and systems-level factors relevant to delivering health care to emergency department (ED) patients who are homeless. METHODS We conducted semistructured interviews with emergency medicine residents from 2 residency programs, 1 in New York City and 1 in a medium-sized northeastern city, from February to September 2012. A team of researchers reviewed transcripts independently and coded text segments using a grounded theory approach. They reconciled differences in code interpretations and generated themes inductively. Data collection and analysis occurred iteratively, and interviews continued until theoretical saturation was achieved. RESULTS From 23 interviews, 3 key themes emerged: (1) use of pattern recognition in identifying and treating patients who are homeless, (2) variations from standard ED care for patients who are homeless, and (3) tensions in navigating the boundaries of ED social care. CONCLUSIONS Our study revealed practical and philosophical tensions in providing social care to patients in the ED who are homeless. Screening for homelessness in the ED and admission practices for patients who are homeless are important areas for future research and intervention with implications for health care costs and patient outcomes.

Emergency Care of Urban Women With Sexually Transmitted Infections : Time to Address Deficiencies

Background: Patient education upon diagnosis of a sexually transmitted infection (STI) may effect changes in high-risk sexual behavior. Objective: Describe emergency department (ED) communication with urban female patients treated for STIs. Methods: This secondary analysis of data collected during a study of ED communication used mixed quantitative and qualitative methods. The medical records of female patients ages 18 to 35 presenting to an urban ED for low abdominal/pelvic pain, gynecological complaints, and urinary symptoms (n = 134) were reviewed for STI testing and treatment proportions. A subsample of 30 audiotaped interactions with women treated for STIs were coded for provider assessment of sexual risks and delivery of STI prevention messages. Results: Audiotape analysis found sexual histories were very limited and only 17% of women received prevention messages. Provider STI treatment had an estimated overall sensitivity of 46% (95% CI, 24.4%–69.0%) and specificity of 66% (95% CI, 61.8%–70.7%). Conclusions: Urban female patients treated for an STI in the ED rarely received recommended STI prevention messages. The study raises policy issues regarding the need for quality indicators in acute STI care. Access to STI treatment in other practice settings or by alternative methods need to be strongly considered.

Using Lean Management to Reduce Emergency Department Length of Stay for Medicine Admissions

Background: The practice of boarding admitted patients in the emergency department (ED) carries negative operational, clinical, and patient satisfaction consequences. Lean tools have been used to improve ED workflow. Interventions focused on reducing ED length of stay (LOS) for admitted patients are less explored. Objective: To evaluate a Lean-based initiative to reduce ED LOS for medicine admissions. Design, Setting, Patients: Prospective quality improvement initiative performed at a single university-affiliated Department of Veterans Affairs (VA) medical center from February 2013 to February 2016. Intervention: We performed a Lean-based multidisciplinary initiative beginning with a rapid process improvement workshop to evaluate current processes, identify root causes of delays, and develop countermeasures. Frontline staff developed standard work for each phase of the ED stay. Units developed a daily management system to reinforce, evaluate, and refine standard work. Measurements: The primary outcome was the change in ED LOS for medicine admissions pre- and postintervention. ED LOS at the intervention site was compared with other similar VA facilities as controls over the same time period using a difference-in-differences approach. Results: ED LOS for medicine admissions reduced 26.4%, from 8.7 to 6.4 hours. Difference-in-differences analysis showed that ED LOS for combined medicine and surgical admissions decreased from 6.7 to 6.0 hours (−0.7 hours, P = .003) at the intervention site compared with no change (5.6 hours, P = .2) at the control sites. Conclusions: We utilized Lean management to significantly reduce ED LOS for medicine admissions. Specifically, the development and management of standard work were key to sustaining these results.
