Effectiveness of Advance Care Planning: What Works, What Doesn't, and What Needs to Change?

An increasing recognition over the past five decades of the importance of patients' autonomy and the right to be able to choose to limit medical treatment at the end of life has led to the development of a number of documents related to advance care planning, including the advance directive, medical power of attorney, and portable orders for life-sustaining treatment (POLST). While these documents are important aspects of advance care planning, without having goals-of-care conversations, a specific plan, and necessary supports to achieve these goals, the documents alone offer a false promise. Healthcare professionals must be trained on how to have indepth goals-of-care conversations with patients and their families, and effectively document the decisions. Advance care planning needs to be viewed as a process that must continue as the patient's health status, social support system, and living environment change. Designating a healthcare representative who participates in goals-of-care conversations and can work with the healthcare team to make "just in time" decisions about care reduces the burden and stress on friends and family. In this article we discuss the strengths and limitations of advance directives, medical power of attorney forms, and POLST forms; propose concrete changes to optimize the effectiveness of each; and present a comprehensive approach to advance care planning that we hope will improve care for those nearing the end of life, and ensure that their wishes and goals to have or to limit treatment are more consistently honored.

Integrating Public Health and Health Care Strategies to Address the Opioid Epidemic: The Oregon Health Authority's Opioid Initiative.

CONTEXT: Oregon is experiencing an opioid overdose epidemic, similar to the United States as a whole. To address this crisis, the Oregon Health Authority (OHA) implemented a strategic Opioid Initiative, convening stakeholders and integrating public health and health care system activities across sectors. Recent data indicate progress: from 2015 to 2016, Oregon had the sharpest decline in prescription opioid overdose deaths of any state. PROGRAM: The Opioid Initiative, launched in 2015, focuses on integrating efforts to improve patient care and safety, and population health, by increasing access to nonopioid pain treatment, supporting medication-assisted treatment and naloxone access for people taking opioids, decreasing opioid prescribing, and using data to inform policies and interventions. IMPLEMENTATION: Four OHA projects highlight the integration: (1) a Medicaid Coordinated Care Organization Performance Improvement Project focused on decreasing risky opioid prescribing; (2) Health Evidence Review Commission guidelines that set coverage standards for opioid and nonopioid back pain treatments for Medicaid recipients; (3) statewide opioid prescribing guidelines; and (4) an opioid data dashboard. Each project involves a partnership between governmental public health, public and private health care systems, and external stakeholders. PROGRESS: From 2015 to 2017, the number of Oregonians on 90 or more Morphine Equivalent Doses (MEDs) decreased by 37%, from 11.1 per 1000 residents quarterly to 7.0 per 1000 residents quarterly. Prescription opioid overdose deaths decreased 20% from 4.5 per 100 000 in 2015 to 3.6 per 100 000 in 2016. Within the Medicaid population, the percentage of clients on 120 or more MEDs for 30 consecutive days decreased 27%, from 2.3% in December 2015 to 1.6% in September 2017. DISCUSSION: Oregon's integrated approach to address the opioid crisis spans public health and health care systems, engages key stakeholders, and uses data and evidence to inform policies. The progress to date is promising and may assist other states seeking to identify effective strategies to decrease opioid prescribing, misuse, and overdose.

Oregon's Death With Dignity Act: 20 Years of Experience to Inform the Debate.

Twenty years ago, Oregon voters approved the Death With Dignity Act, making Oregon the first state in the United States to allow physicians to prescribe medications to be self-administered by terminally ill patients to hasten their death. This report summarizes the experience in Oregon, including the numbers and types of participating patients and providers. These data should inform the ongoing policy debate as additional jurisdictions consider such legislation.

Surveillance of Extrapulmonary Nontuberculous Mycobacteria Infections, Oregon, USA, 2007-2012.

Limited data are available describing extrapulmonary nontuberculous mycobacteria (NTM) infections in the general population. We describe results from statewide population-based laboratory surveillance in Oregon, USA, during 2007-2012. We defined a case of extrapulmonary NTM infection as >1 isolate from skin/soft tissue, disseminated sites, lymph node, joint, or other sites. The annual incidence of extrapulmonary NTM infection (other than Mycobacterium gordonae) was stable, averaging 1.5 cases/100,000 population. Median age of the 334 patients was 51 years, and 53% of patients were female. Half of cases were caused by M. avium complex, but rapid-growing NTM species accounted for one third of cases. Most extrapulmonary NTM infections are skin/soft tissue. Compared with pulmonary NTM infection, more extrapulmonary infections are caused by rapid-growing NTM species. the designation of NTM as a reportable disease in Oregon in 2014 will result in better detection of changes in the incidence and patterns of disease in the future.

Electronic Cigarettes as an Introductory Tobacco Product Among Eighth and 11th Grade Tobacco Users - Oregon, 2015.

During 2011-2015, increased electronic cigarette (e-cigarette) and hookah use offset declines in cigarette and other tobacco product use among youths (persons aged <18 years) (1). Limited information exists about which tobacco product introduced youths to tobacco product use. Patterns of first use of e-cigarettes among Oregon youths who were tobacco users were assessed in the Oregon Healthy Teens 2015 survey, a cross-sectional survey of eighth and 11th grade students in Oregon. Respondents were asked, "The very first time you used any tobacco or vaping product, which type of product did you use?" Among students who had ever used any tobacco product (ever users), e-cigarettes were the most common introductory tobacco product reported by both eighth (43.5%) and 11th (34.4%) grade students. Among students who used a tobacco product for ≥1 day during the past 30 days (current users), e-cigarettes were the most common introductory tobacco product reported by eighth grade students (44.4%) and the second most common introductory tobacco product reported by 11th grade students (31.0%). Introductory use of e-cigarettes was commonly reported among youths in Oregon who were ever or current tobacco users, underscoring the importance of proven interventions to prevent all forms of tobacco use among youths (2,3).

A case-control study evaluating the role of internet meet-up sites and mobile telephone applications in influencing a syphilis outbreak: Multnomah County, Oregon, USA 2014.

OBJECTIVES: Early syphilis in Multnomah County, Oregon, USA, increased 16-fold during 2007-2013. Cases predominantly occurred among men who have sex with men (MSM); 55% were HIV coinfected. We conducted a case-control study to evaluate the association between meeting sex partners online and early syphilis. METHODS: Cases subjects (cases) were Multnomah County resident, English speaking, MSM, aged ≥18 years with laboratory-confirmed early syphilis reported 1 January to 31 December 2013. We recruited two MSM controls subjects (controls) per case, frequency matched by HIV status and age. Participants completed self-administered questionnaires. We performed multivariable logistic regression. RESULTS: Seventy per cent (40/57) of cases and 42% (50/119) of controls met partners online (p<0.001). Cases more frequently met partners online (adjusted OR (aOR)=3.0; 95% CI 1.2 to 6.7), controlling for presumptive confounders. Cases reported more partners than controls (medians 5, 2; p<0.001). When including number of partners, aOR decreased to 1.4 (95% CI 0.5 to 3.9). CONCLUSIONS: Early syphilis was associated with meeting partners online. We believe this association may be related to number of sex partners acting as an intermediate variable between use of online resources to meet sex partners and early syphilis. Online meet-up sites might represent areas for public health interventions targeting at-risk individuals.

Notes from the Field: Shigellosis Outbreak Among Men Who Have Sex with Men and Homeless Persons - Oregon, 2015-2016.

In July 2015, Shigella sonnei infections with a specific pulsed-field gel electrophoresis (PFGE) pattern linked to a multistate outbreak were recognized among men who have sex with men (MSM) in the Portland metropolitan area, and an outbreak investigation was initiated. During November 2015, isolates with PFGE patterns indistinguishable from the outbreak strain were identified in cases reported in four women, none of whom had epidemiologic links to other affected persons; however, three reported homelessness. In the ensuing months, additional S. sonnei infections were reported among homeless persons in the Portland area.

Influenza vaccination of pregnant women: attitudes and behaviors of Oregon physician prenatal care providers.

In spite of increased risk of influenza complications during pregnancy, only half of US pregnant women get influenza vaccination. We surveyed physician prenatal care providers in Oregon to assess their knowledge and behaviors regarding vaccination of pregnant women. From September through November 2011, a state-wide survey was mailed to a simple random sample (n = 1,114) of Oregon obstetricians and family physicians. The response rate was 44.5 %. Of 496 survey respondents, 187 (37.7 %) had provided prenatal care within the last 12 months. Of these, 88.5 % reported that they routinely recommended influenza vaccine to healthy pregnant patients. No significant differences in vaccine recommendation were found by specialty, practice location, number of providers in their practice, physician gender or years in practice. In multivariable regression analysis, routinely recommending influenza vaccine was significantly associated with younger physician age [adjusted odds ratio (AOR) 2.01, 95 % confidence interval (CI) 1.29-3.13] and greater number of pregnant patients seen per week (AOR 1.95, 95 % CI 1.25-3.06). Among rural physicians, fewer obstetricians (90.3 %) than family physicians (98.5 %) had vaccine-appropriate storage units (p = 0.001). Most physician prenatal care providers understand the importance of influenza vaccination during pregnancy. To increase influenza vaccine coverage among pregnant women, it will be necessary to identify and address patient barriers to receiving influenza vaccination during pregnancy.

Distinguishing tuberculosis from nontuberculous mycobacteria lung disease, Oregon, USA.

To determine whether tuberculosis (TB) and nontuberculous mycobacteria (NTM) infection patients could be distinguished from one another with limited information, we compared pulmonary TB and NTM patients during 2005-2006. Our finding that age, birthplace, and presence of chronic obstructive pulmonary disease could differentiate TB and NTM disease could assist tuberculosis control efforts.

Pulmonary nontuberculous mycobacterial disease prevalence and clinical features: an emerging public health disease.

RATIONALE: Respiratory specimens with nontuberculous mycobacteria (NTM) are increasingly common; however, pulmonary disease prevalence is unknown. OBJECTIVES: To determine the disease prevalence, clinical features, and risk factors for NTM disease, and to examine the predictive value of the microbiologic criteria of the American Thoracic Society (ATS)/Infectious Diseases Society of America (IDSA) pulmonary NTM case definition for true NTM disease. METHODS: We identified all Oregon residents during 2005-2006 with at least one respiratory mycobacterial isolate. From a population-based subset of these patients, we collected clinical and radiologic information and used the ATS/IDSA pulmonary NTM disease criteria to define disease. MEASUREMENTS AND MAIN RESULTS: In the 2-year time period, 807 Oregonians had one or more respiratory NTM isolates. Four hundred and seven (50%) resided within the Portland metropolitan region, among which 283 (70%) had evaluable clinical records. For those with records, 134 (47%) met ATS/IDSA pulmonary NTM disease criteria for a minimum overall 2-year period prevalence of 8.6/100,000 persons, and 20.4/100,000 in those at least 50 years of age within the Portland region. Case subjects were 66 years of age (median; range, 12-92 yr), frequently female (59%), and most with disease caused by Mycobacterium avium complex (88%). Cavitation (24.5%), bronchiectasis (16%), chronic obstructive pulmonary disease (28%), and immunosuppressive therapy (25.5%) were common. Eighty-six percent of patients meeting the ATS/IDSA microbiologic criteria for disease also met the full ATS/IDSA disease criteria. CONCLUSIONS: Respiratory NTM isolates frequently represent disease. Pulmonary NTM disease is not uncommon, particularly among elderly females. The ATS/IDSA microbiologic criteria are highly predictive of disease and could be useful for laboratory-based NTM disease surveillance.

Comparison of survey methods in norovirus outbreak investigation, Oregon, USA, 2009.

We compared data from an Internet-based survey and a telephone-based survey during a 2009 norovirus outbreak in Oregon. Survey initiation, timeliness of response, and attack rates were comparable, but participants were less likely to complete Internet questions. Internet-based surveys permit efficient data collection but should be designed to maximize complete responses.

Risk factors for sporadic shigellosis, FoodNet 2005.

BACKGROUND: An estimated 450,000 cases of shigellosis occur annually in the United States. Outbreaks have been associated with food, water, child daycare centers, and men who have sex with men. However, for sporadic infections, which account for the majority of cases, risk exposures are poorly characterized. METHODS: Foodborne Diseases Active Surveillance Network (FoodNet) conducts active, laboratory-based shigellosis surveillance in 10 US sites. We interviewed cases with illness onset during 2005 about exposures during the week before symptom onset using a standardized questionnaire. The proportion of patients who denied nonfood risks was used to estimate the burden attributable to foodborne transmission. RESULTS: Overall, 1494 cases were identified. The approximate incidence was 3.9/100,000, with the highest rates among children aged 1-4 years (16.4) and Hispanics (8.4). Of the 929 cases interviewed, 223 (24%) reported international travel in the week before symptom onset. Of the 626 nontraveling cases with complete risk factor information, 298 (48%) reported exposure to daycare or a household member with diarrhea; 99 (16%) reported drinking untreated water or recreational exposure to water; and 16 (3%) reported sexual contact with a person with diarrhea. Two hundred and fifty-nine (41%) denied all nonfood exposures examined. CONCLUSIONS: Sporadic shigellosis is most common among young children and Hispanics. Common exposures include international travel and contact with ill persons or daycare. However, more than one-third of US shigellosis cases annually might be due to food consumed in the United States.

Nontuberculous mycobacterial disease prevalence and risk factors: a changing epidemiology.

BACKGROUND: Nontuberculous mycobacteria (NTM) are important human pathogens, yet little is known about disease prevalence in the United States. Reports suggest prevalence has increased, particularly in women, but population-based data to substantiate this are lacking. We sought to estimate NTM disease prevalence in Oregon, and describe disease by site, species, and patient demographic characteristics. METHODS: We contacted laboratories that performed mycobacterial cultures on Oregon residents in 2005-2006. For each isolate, we obtained source, collection date, species, and patient demographics. We used the microbiologic component of the American Thoracic Society/Infectious Diseases Society of America's pulmonary NTM disease criteria to define cases of pulmonary NTM, and patients with isolates from a normally sterile site were classified as having extrapulmonary disease. RESULTS: We identified 933 patients with > or =1 NTM isolate. Of these, 527 (56%) met the case definition (annualized prevalence, 7.2 cases per 100,000 persons). Pulmonary cases predominated (5.6 cases per 100,000 persons), followed by skin/soft-tissue cases (0.9 cases per 100,000 persons). Mycobacterium avium complex was the most common species identified in pulmonary cases (4.7 cases per 100,000 persons). Pulmonary disease prevalence was significantly higher in women (6.4 cases per 100,000 persons) than men (4.7 cases per 100,000 persons) and was highest in persons aged >50 years (15.5 cases per 100,000 persons). CONCLUSIONS: NTM are frequently isolated from Oregon residents; more than one-half of all isolates likely represent true disease. Pulmonary NTM is most common among elderly women, and M. avium causes most disease. Future efforts to monitor disease trends should be undertaken, and efforts made to validate the use of the ATS/IDSA microbiologic criteria alone to predict pulmonary NTM disease.

Acute cannabis toxicity.

Objective: We describe the clinical effects of, and products associated with, acute exposures to cannabis during the early legalization period of recreational cannabis in Oregon and Alaska. Methods: This was an observational study of Oregon/Alaska Poison Center data between 4 December 2015 and 15 April 2017. A standardized data collection instrument was created for this study that captured information about cannabis product description, route of exposure, intentional vs unintentional exposure, product dose, product manufacture source, product ownership source, initial vital signs, clinical signs and symptoms, and subject disposition. Subjects were included if the Poison Center received a call about an acute exposure to cannabis from the subject, subject's family member or friend, or healthcare worker participating in the subject's care. Subjects were excluded if there was no evident exposure, the exposure was chronic, there were co-ingestants, or the subject was non-human (e.g. pet). Results: Two hundred fifty three individuals were acutely exposed to cannabis (median age 20 years; range 8 months - 96 years; 54.2% males): 71 (28.1%) children (<12 years), 42 (16.6%) adolescents (12-17 years), and 140 (55.3%) adults (≥18 years). Children were most likely to unintentionally (98.6%) ingest (97.2%) homemade (35.2%) edibles (64.8%) belonging to a family member (73.2%) and experience sedation (52.1%). Adults were most likely to intentionally (88.6%) ingest (66.4%) retail (40.0%) edibles (48.6%) and experience neuroexcitation (47.1%). Adolescents' exposures had similarities to both adult and children; they were most likely to intentionally (81.0%) ingest (50.0%) homemade (23.8%) edibles (45.2%) belonging to a friend (47.3%) and to experience either neuroexcitation (42.9%) or sedation (40.5%). Among all ages, tachycardia and neuroexcitation were more likely following inhalation exposures compared to ingestions. Eight subjects were admitted to an intensive care unit, including three patients who were intubated; one subject died. Edibles were the most common products to cause symptoms in all age groups, while concentrated products were more likely to lead to intubation, especially when ingested. Children in particular had a higher likelihood of intensive care unit admission and intubation following exposure to concentrated products. Conclusions: Neurotoxicity is common after acute cannabis exposures. Children experienced unintentional exposures, particularly within the home and occasionally with major adverse outcomes. Concentrated products such as resins and liquid concentrates were associated with greater toxicity than other cannabis products. These findings may help guide other states during the early retail cannabis legalization period.

Using diagnostic codes to screen for intimate partner violence in Oregon emergency departments and hospitals.

OBJECTIVES: Many of the 2.5 million Americans assaulted annually by intimate partners seek medical care. This project evaluated diagnostic codes indicative of intimate partner violence (IPV) in Oregon hospital and emergency department (ED) records to determine predictive value positive (PVP), sensitivity, and usefulness in routine surveillance. Statewide incidence of care for IPV was calculated and victims and episodes characterized. METHODS: The study was a review of medical records assigned > or = 1 diagnostic codes thought predictive of IPV. Sensitivity was estimated by comparing the number of confirmed victims identified with the number predicted by statewide telephone survey. Patients were aged > or = 12 years, treated in any of 58 EDs or hospitals in Oregon during 2000, and discharged with one of three primary or 12 provisional codes suggestive of IPV. Outcome measures were number of victims detected, PPV and sensitivity of codes for detection of IPV, and description of victims. RESULTS: Of 58 hospitals, 52 (90%) provided records. Case finding using primary codes identified 639 victims, 23% of all estimated female victims seen in EDs or hospitalized statewide. PVP was 94% (639/677). Provisional codes increased sensitivity (51%) but reduced PVP (50%). Highest incidence occurred in women aged 20-39 years, and those who were black. Hospitalizations were highest among women aged > or = 50 years, black people, or those with comorbid illness. CONCLUSIONS: Three diagnostic codes used for case finding detect approximately one-quarter of ED- and hospital-treated victims, complement surveys, and facilitate description of injured victims.

Canine and human factors related to dog bite injuries.

OBJECTIVE: To identify physical traits of biting dogs and characteristics of injured persons and dog owners associated with bite situations for use in public health prevention activities. DESIGN: Retrospective cohort study. STUDY POPULATION: Licensed dog and dog bite report data from June 30, 2002, to July 1, 2003, that were obtained from Animal Control Services of Multnomah County, Oregon. PROCEDURES: To determine the canine and human factors associated with dog bite injuries, the number of bites, dog and injured person characteristics, and the overall canine population were evaluated. Dog owner characteristics at the block group level were defined by use of geographic information system software through 2000 census information based on place of residence. RESULTS: During the study period, 636 dog bites were reported to Animal Control Services, and 47,526 dogs were licensed in Multnomah County. Risk factors associated with biting dogs included breed (terrier, working, herding, and nonsporting breeds), being a sexually intact male, and purebred status. Male children aged 5 to 9 years had the highest rate of injury (178 bites/100,000 children). Biting dogs were more likely than nonbiting dogs to live in neighborhoods where the residents' median incomes were less than the county median income value ($41,278). CONCLUSIONS AND CLINICAL RELEVANCE: Dog bites continue to be a source of preventable injury. Prevention programs should target owners of sexually intact male and purebred dogs and owners who live in lower income neighborhoods.

Chlamydia Retesting Among Safety-Net Clinic Patients: Infertility Prevention Project.

BACKGROUND: Due to high reinfection rates, the Centers for Disease Control and Prevention (CDC) recommend retesting everyone diagnosed with chlamydia after treatment. However, retesting rates are often low, and research on retesting is limited. METHODS: Infertility Prevention Project (IPP) was a national chlamydia screening and treatment project in the United States. We completed a retrospective longitudinal analysis using IPP testing data from 8,266 women with at least 1 positive test result from 2010 to 2013. We calculated the proportion of women retested 2-12 months after a chlamydia diagnosis and used Cox proportional hazards models to explore associated factors. RESULTS: Only 32% of women had evidence of retesting by 12 months of follow-up. Being younger (multivariate hazard ratio [mHR]: 0.96; 95% confidence interval [CI]: 0.95-0.96), black (mHR: 1.29; 95% CI: 1.12-1.50), or attending a county sexually transmitted diseases (STD; mHR: 1.91; 95% CI: 1.68-2.17), county family planning (mHR: 1.53; 95% CI: 1.39-1.69), or school-based (mHR: 2.34; 95% CI: 2.07-2.65) clinic relative to a nonprofit community health clinic were associated with increased retesting rates. CONCLUSIONS: Less than one-third of women are retested. Our results show that some clinic settings may have systematic differences which facilitate retesting, such as use of automated reminders, closed patient populations, and makeup of patient populations. Investigation of clinical environments through site visits and further data analyses may be keys to improving retesting rates.

Heavy precipitation as a risk factor for shigellosis among homeless persons during an outbreak - Oregon, 2015-2016.

OBJECTIVES: Shigella species are the third most common cause of bacterial gastroenteritis in the United States. During a Shigella sonnei outbreak in Oregon from July 2015 through June 2016, Shigella cases spread among homeless persons with onset of the wettest rainy season on record. METHODS: We conducted time series analyses using Poisson regression to determine if a temporal association between precipitation and shigellosis incidence existed. Models were stratified by housing status. RESULTS: Among 105 infections identified, 45 (43%) occurred in homeless persons. With increasing precipitation, cases increased among homeless persons (relative risk [RR] = 1.36 per inch of precipitation during the exposure period; 95% confidence interval [CI] = 1.17-1.59), but not among housed persons (RR = 1.04; 95% CI 0.86-1.25). CONCLUSIONS: Heavy precipitation likely contributed to shigellosis transmission among homeless persons during this outbreak. When heavy precipitation is forecast, organizations working with homeless persons could consider taking proactive measures to mitigate spread of enteric infections.

Clostridium difficile-associated disease in Oregon: increasing incidence and hospital-level risk factors.

BACKGROUND: The incidence of Clostridium difficile-associated disease (CDAD) appears to be increasing. Population-based estimates of disease have been limited, and analyses of hospital-level risk factors for CDAD are lacking. We sought to determine the incidence and trends of CDAD in Oregon and to identify hospital-level factors associated with increases in disease. METHODS: We analyzed hospital discharge data to calculate the incidence and to describe trends of CDAD in Oregon from 1995 through 2002. We administered questionnaires to hospital laboratory directors, infection control practitioners, and pharmacists to determine the status of laboratory, infection control, and pharmacy policies over time. RESULTS: The overall incidence of CDAD in Oregon was 3.5 case patients per 10,000 residents in 2002. Incidence increased from 1.4 to 3.3 cases per 1,000 hospital discharges from 1995 to 2002. Rates of disease increased most in hospitals with licensed bed capacity of more than 250 beds and more than 5 intensive care unit beds. Few laboratories, infection control practitioners, and pharmacists were able to identify changes in specific policies over the study period. CONCLUSIONS: This is the first study to determine a statewide population-based incidence of CDAD. Incidence of CDAD in Oregon has more than doubled over the past decade; larger hospitals experienced the greatest increase in disease rates. We did not identify hospital-level policies that could explain the increase. A study of patients with CDAD at the hospitals with the largest increases is underway to further identify risk factors.
