Mortality in patients hospitalized for asthma exacerbations in the United States.

RATIONALE: Hospitalizations for asthma exacerbations are common in the United States, but there are no national estimates of outcomes in this population. It is also not known if race disparities in asthma deaths exist among hospitalized patients. OBJECTIVES: To estimate outcomes of patients hospitalized for asthma in the United States and to determine if the risk of death in this population is higher among black patients compared with white patients. METHODS: We used the Nationwide Inpatient Sample for 2000. Admissions for asthma exacerbations among patients > 5 yr of age were included. Mortality was the primary outcome; secondary outcomes were length of stay and total hospital charges. MEASUREMENTS AND MAIN RESULTS: In-hospital asthma mortality was 0.5% (99% confidence interval [CI], 0.4-0.6), with mean hospital stay of 2.7 d (99% CI, 2.6-2.8 d) and 9,078 dollars (99% CI, 8,300-9,855 dollars) in hospital charges. Deaths in this population accounted for about one-third of all asthma deaths reported in the United States. Black patients hospitalized for asthma exacerbations were less likely to die when compared with white patients (0.3 vs. 0.6%; p < 0.001). However, in multivariable analyses, there were no significant race differences in hospital deaths. CONCLUSIONS: Mortality among patients hospitalized for asthma exacerbations accounts for one-third of all deaths from asthma. The higher overall risk of death from asthma in black patients compared with white patients in the United States is not explained by race differences in hospital deaths and therefore is attributable to factors preceding hospitalization.

Asthma-related health status determinants of environmental control practices for inner-city preschool children.

BACKGROUND: Asthma guidelines recommend environmental control practices (ECPs) to improve asthma health. In the inner city, where asthma morbidity is high, it is not known whether children's health status affects the use of ECPs. OBJECTIVE: To investigate health status determinants of ECPs in the homes of children with asthma. METHODS: Caregivers of children aged 2 to 6 years with (n = 150) and without (n = 150) asthma completed a survey about ECPs. Atopic status was determined by means of skin prick testing. RESULTS: Most ECPs were similarly practiced, regardless of whether the child had asthma. Only pet avoidance was more common in children with asthma (30% vs 19%). Asthma severity and recent acute health care visits for asthma were not associated with ECP use. Most ECPs were not linked to allergen sensitization (eg, mite and mouse), although cockroach-sensitized children were more likely to have cockroach control than nonsensitized individuals (65% vs 45%). Caregivers of asthmatic children with rhinitis were more likely than those without rhinitis to report ECPs, including pet avoidance (44% vs 15%), smoking avoidance (78% vs 53%), cockroach control (65% vs 42%), mouse control (78% vs 42%), air-conditioning (45% vs 24%), and allergyproof covers (7% vs 0%). CONCLUSIONS: The presence of asthma, asthma severity, and allergen sensitization seem to have little relationship to ECP use in the homes of inner-city children. Rhinitis was consistently linked to ECPs, which suggests that caregivers may make changes in the home environment for upper airway but not lower airway symptoms.

Household mouse allergen exposure and asthma morbidity in inner-city preschool children.

BACKGROUND: Inner-city children experience disproportionate asthma morbidity, and suspected reasons include indoor environmental exposures. OBJECTIVE: To determine if mouse allergen exposure is a risk factor for asthma morbidity. METHODS: Preschool children with asthma were recruited from inner-city Baltimore, MD. Skin testing was performed and blood was collected at the baseline visit for quantification of mouse allergen specific IgE. A questionnaire evaluated symptoms, medication, and health care use at baseline, 3 months, and 6 months. A trained technician collected dust samples from the child's home for analysis of Mus m 1 at baseline, 3 months, and 6 months. Outcomes were compared between mouse-sensitized, highly exposed children and all other children. RESULTS: A total of 127 children had complete data for mouse sensitization status and bedroom settled dust mouse allergen levels at baseline. The mean age of the children was 4.4 years, 92% were African American, and 26% were sensitized to mouse. Mouse-sensitized children exposed to higher levels of Mus m 1 (>0.5 microg/g) had 50% more days of symptoms (incidence rate ratio [IRR], 1.5; 95% confidence interval [CI], 1.1-2.1) and 80% more days of beta-agonist use than other children (IRR, 1.8; 95% CI, 1.3-2.5). Children in the sensitized and highly exposed group were also more likely to have an unscheduled physician visit (odds ratio [OR], 3.1; 95% CI, 1.6-6.3), emergency department visit (OR, 2.1; 95% CI, 1.1-4.1), and hospitalization (OR, 36.6; 95% CI, 4.1-327.3) than other children. These associations between mouse allergen exposure and asthma symptoms and morbidity remained statistically significant after adjusting for potential confounders, including atopy and cockroach sensitization and exposure. CONCLUSIONS: In mouse-sensitized inner-city children, exposure to mouse allergen may be an important cause of asthma morbidity.

Depressive symptoms and adherence to asthma therapy after hospital discharge.

STUDY OBJECTIVES: To evaluate the effect of depressive symptoms on adherence to therapy after discharge in patients hospitalized for asthma exacerbations. DESIGN: Prospective cohort study in which depressive symptoms were assessed during hospitalization and use of asthma medications was electronically monitored for 2 weeks after discharge. SETTING: Inner-city academic hospital in Baltimore, MD. PATIENTS: Patients were 59 adults with a mean age of 43.2 +/- 10.9 years (+/- SD), who were mostly female (64%), African American (80%), and were hospitalized for an asthma exacerbation. MEASUREMENT AND RESULTS: Depressive symptoms were assessed with the Center for Epidemiological Studies-Depression scale. Electronic monitors were used to evaluate inhaled corticosteroid and oral corticosteroid use for up to 2 weeks after discharge. Forty-one percent of patients had high levels of depressive symptoms. Mean adherence to therapy was significantly lower in patients with (vs without) high levels of depressive symptoms (60 +/- 26% vs 74 +/- 21%, p + 0.02). Even after controlling for age, gender, and education, depressive symptoms were a significant and independent predictor of poorer adherence. High levels of depressive symptoms were associated with a 11.4-fold increase (95% confidence interval, 2.2 to 58.2) in the odds of poor adherence to therapy after adjustment for potential confounders. CONCLUSIONS: Depressive symptoms are common in inner-city adults hospitalized for asthma exacerbations and identify a subset of patients at high risk for poor adherence to asthma therapy after discharge. Further research is needed to determine if screening for and treating depression improves adherence and asthma outcomes in this population.

Tailored education may reduce health literacy disparities in asthma self-management.

RATIONALE: Although inadequate health literacy has been associated with lower asthma medication knowledge and worse metered-dose inhaler (MDI) technique, the relationship between health literacy and the capacity to learn asthma self-management skills is unknown. OBJECTIVES: In this prospective cohort study of adults hospitalized for severe asthma exacerbations at two inner-city hospitals, we examined the relationship between inadequate health literacy and difficulties learning and retaining instructions about discharge medications and appropriate MDI technique. METHODS: At hospital discharge, participants received one-on-one, 30-min, guideline-based, written and oral instruction about their asthma discharge regimen as well as appropriate MDI technique. MEASUREMENTS AND MAIN RESULTS: Seventy-three patients were enrolled. Inadequate health literacy was identified in 16 (22%) participants. Before instruction, inadequate health literacy was associated with lower asthma medication knowledge (5.2/10 vs. 7.2/10, p < 0.001) and worse MDI technique (3.2/6 vs. 3.9/6, p = 0.03). However, inadequate health literacy was not associated with difficulty learning (p = 0.33) or retaining (p = 0.35) instructions about the discharge regimen. Similarly, inadequate health literacy was not associated with difficulty learning (p = 0.26) or retaining (p = 0.97) appropriate MDI technique. Results were similar in multivariable models adjusted for demographic characteristics and asthma severity indicators. CONCLUSIONS: These findings suggest that inadequate health literacy is a surmountable barrier to learning and remembering key asthma self-management skills.

Indoor exposures to air pollutants and allergens in the homes of asthmatic children in inner-city Baltimore.

This paper presents indoor air pollutant concentrations and allergen levels collected from the homes of 100 Baltimore city asthmatic children participating in an asthma intervention trial. Particulate matter (PM), NO2, and O3 samples were collected over 72 h in the child's sleeping room. Time-resolved PM was also assessed using a portable direct-reading nephelometer. Dust allergen samples were collected from the child's bedroom, the family room, and the kitchen. The mean PM10 concentration, 56.5+/-40.7 microg/m3, is 25% higher than the PM2.5 concentration (N=90), 45.1+/-37.5 microg/m3. PM concentrations measured using a nephelometer are consistent and highly correlated with gravimetric estimates. Smoking households' average PM2.5 and PM10 concentrations are 33-54 microg/m3 greater than those of nonsmoking houses, with each cigarette smoked adding 1.0 microm/m3 to indoor PM2.5 and PM10 concentrations. Large percentages of NO2 and O3 samples, 25% and 75%, respectively, were below the limit of detection. The mean NO2 indoor concentration is 31.6+/-40.2 ppb, while the mean indoor O3 concentration in the ozone season was 3.3+/-7.7 ppb. The levels of allergens are similar to those found in other inner cities. Results presented in this paper indicate that asthmatic children in Baltimore are exposed to elevated allergens and indoor air pollutants. Understanding this combined insult may help to explain the differential asthma burden between inner-city and non-inner-city children.

Corticosteroid use after hospital discharge among high-risk adults with asthma.

Despite the efficacy of corticosteroid therapy, patients hospitalized for asthma exacerbations are at high risk for re-exacerbation and death after discharge. The objective of this prospective cohort study was to evaluate adherence to inhaled corticosteroids (ICS) and oral corticosteroids (OCS) after discharge in adults hospitalized for asthma exacerbations. ICS and OCS were equipped with electronic medication monitors and were provided at discharge. Adherence (use/prescribed use x 100%) was measured by self-report and canister weight (ICS), pill count (OCS), and electronic medication monitors (both ICS and OCS) 2 weeks after discharge. Poor adherence was defined as adherence of less than 50%. The Asthma Control Questionnaire was used to assess symptom control. Sixty patients were enrolled (age 42.2 years, 98.3% African American, 65.0% female, 46.7% with history of near-fatal asthma). Electronically measured adherence to both corticosteroids dropped to approximately 50% within 7 days of discharge. Poor adherence to both corticosteroids predicted significantly worse symptom control (p = 0.04). Self-report, canister weight, and pill count all had low sensitivity (29.2%, 65.0%, and 7.7%, respectively) for detecting poor adherence. We conclude that adherence to ICS and OCS deteriorates within days of hospital discharge but may not be recognized in a substantial proportion of patients.

A prospective, controlled trial of a protocol-based strategy to discontinue mechanical ventilation.

Weaning protocols can improve outcomes, but their efficacy may vary with patient and staff characteristics. In this prospective, controlled trial, we compared protocol-based weaning to usual, physician-directed weaning in a closed medical intensive care unit (ICU) with high physician staffing levels and structured, system-based rounds. Adult patients requiring mechanical ventilation for more than 24 hours were assigned to usual care (UC) or protocol weaning based on their hospital identification number. Patients assigned to UC (n=145) were managed at their physicians' discretion. Patients assigned to protocol (n=154) underwent daily screening and a spontaneous breathing trial by respiratory and nursing staff without physician intervention. There were no significant baseline differences in patient characteristics between groups. The proportion of patients (protocol vs. UC) who successfully discontinued mechanical ventilation (74.7% vs. 75.2%, p=0.92), duration of mechanical ventilation (median [interquartile range]: 60.4 hours [28.6-167.0 hours] vs. 68.0 hours [27.1-169.3 hours], p=0.61), ICU (25.3% vs. 28.3%) and hospital mortality (36.4% vs. 33.1%), ICU length of stay (115 vs. 146 hours), and rates of reinstituting mechanical ventilation (10.3% vs. 9.0%) was similar. We conclude that protocol-directed weaning may be unnecessary in a closed ICU with generous physician staffing and structured rounds.

Methods and issues in conducting a community-based environmental randomized trial.

The environment is suspected to play an important role in the prevalence and severity of asthma in inner-city children. This paper describes the implementation and baseline data of an inner-city community-based participatory research clinical trial designed to test the effectiveness of a pollutant and allergen control strategy on children's asthma morbidity. Participants were 100 elementary-school-aged children with asthma, graduates of a school-based asthma education program in East Baltimore. The intervention for half of the randomly assigned families consisted of environmental control education, allergen-proof encasements, pest extermination, and a HEPA air cleaner at the beginning of the study. Controls received the same at the end of the study. Participants visited a clinic for questionnaires, allergy skin testing, spirometry, and blood sample at baseline and 12 months. Home environments, NO(2), O(3), airborne particulates, and allergens were evaluated at baseline and at 6 and 12 months. Asthma morbidity and adherence was assessed quarterly. Collaboration with the community proved very beneficial in creating a study design and procedures acceptable to an inner-city community.

Emotional quality-of-life and outcomes in adolescents with asthma.

OBJECTIVE: Examine the association between emotional quality-of-life (QOL) and asthma morbidity in adolescents with asthma. STUDY DESIGN: Cross-sectional survey of 185 adolescents with asthma 11 to 17 years of age cared for in three managed care organizations (MCOs) in the United States. The asthma-specific Pediatric Asthma Quality of Life Questionnaire (PAQLQ) and a short version of the generic Child Health and Illness Profile-Adolescent Edition (CHIP-AE) were used to assess emotional QOL. Asthma morbidity measures were: asthma control, emergency department (ED) visits, hospitalizations, doctor visits for worsening asthma, and missed school because of asthma. RESULTS: Of the adolescents surveyed, 45% reported feeling depressed, 41% had ED visits, and 30% missed >or=1 day of school because of asthma. Poorer asthma-specific emotional QOL was associated with poorer control of asthma symptoms ( P < .0001), missed school (OR 7.1, P < .05), and doctor visits for worsened asthma (OR = 7.0, P < .05). CONCLUSIONS: Emotional symptoms related to asthma are common in adolescents with persistent asthma and asthma-specific QOL is related to increased asthma morbidity, healthcare use, and school absenteeism. Adolescents with high morbidity from asthma exhibit poorer QOL. Therefore, the evaluation of asthma-specific emotional QOL should be included in the assessment of adolescents with asthma.

Trends in use of inhaled corticosteroids for asthma management: 1994-1998.

PURPOSE: To evaluate trends in prescribing of inhaled corticosteroids for asthma between 1994 and 1998 and patterns of prescribing in relation to selected physician characteristics. METHODS: Using a HMO database, a physician sample (N = 335) was linked to patient encounter data and pharmacy claims (N = 51,345) for asthma patients ages 5 to 45 years (N = 6,944). Longitudinal and cross-sectional analytic methods were used to examine physician prescribing patterns across the study period. RESULTS: The percent of physicians prescribing an inhaled corticosteroid increased over time with consistently greater prescribing among specialists. Annual comparisons by specialty groups revealed that specialists (allergy and pulmonary) prescribed inhaled steroids to a larger proportion of their patients than generalists (family practice, internal medicine, pediatrics, pediatric emergency department); (range: 0.61-0.69 vs. 0.31-0.39, p < .01). The lowest proportions were found among pediatric emergency department physicians (range: 0.00-0.10) and pediatricians (range: 0.17-0.27). CONCLUSIONS: Significant linear trends in either physician group were not observed during this 5-year period. Differences across physician groups were evident.

Maternal depressive symptoms and adherence to therapy in inner-city children with asthma.

CONTEXT: Little is known about how depressive symptoms in mothers affects illness management in inner-city children with asthma. OBJECTIVE: Our goal was to determine how maternal depressive symptoms influence child medication adherence, impact of the child's asthma on the mother, and maternal attitudes and beliefs. METHODS: Baseline and 6-month surveys were administered to 177 mothers of young minority children with asthma in inner-city Baltimore, MD and Washington, DC. Medication adherence, disruptiveness of asthma, and select attitudes toward illness and asthma therapy were measured. Six-month data (N = 158) were used to prospectively evaluate long-term symptom control and emergency department use. Independent variables included asthma morbidity, age, depressive symptoms, and other psychosocial data. RESULTS: No difference in child asthma morbidity was observed between mothers high and low in depressive symptoms. However, mothers with high depressive symptoms reported significantly more problems with their child using inhalers properly (odds ratio [OR]: 5.0; 95% confidence interval [CI]: 1.3-18.9) and forgetting doses (OR: 4.2; 95% CI: 1.4-12.4). Depressive symptoms were also associated with greater emotional distress and interference with daily activities caused by the child's asthma, along with less confidence in asthma medications, ability to control asthma symptoms, and self-efficacy to cope with acute asthma episodes. In addition, depressed mothers reported less understanding about their child's medications and use (OR: 7.7; 95% CI: 1.7-35.9). Baseline asthma morbidity, maternal depression scores, and family income were independently associated with asthma symptoms 6 months later, whereas medication adherence was not predictive of subsequent asthma morbidity or emergency department use. CONCLUSIONS: Maternal depressive symptoms were not associated with child asthma morbidity but were associated with a constellation of beliefs and attitudes that may significantly influence adherence to asthma medications and illness management. Identifying and addressing poor psychological adjustment in mothers is important when developing a child's asthma treatment and may facilitate parent-provider communication, medication adherence, and asthma management among inner-city children.

Knowledge and practice of dust mite control by specialty care.

BACKGROUND: Dust mites are the primary indoor allergen risk for increasing asthma attacks and morbidity. Adherence to allergen avoidance recommendations decreases bronchial reactivity and asthma morbidity. OBJECTIVE: This study compared the knowledge and practice of environmental control advice of families of children with asthma seen by an allergist or a pediatrician. Studies suggest that knowledge and practice of environmental control recommendations is inconsistent. METHODS: Subjects were aged 6 to 17 years, diagnosed with asthma, and had positive skin test to dust mites. There were 114 eligible pediatric patients, and 69 had also seen an allergist before the study. An in-home evaluation was completed during which parents were asked about environmental control knowledge and practice. An environmental technician then completed a walk-through evaluation to observe which recommendations were implemented in the home. RESULTS: Families who saw an allergist demonstrated significantly greater awareness of environmental control recommendations for dust mite allergens than those who had not. Knowledge and placement of allergen-proof mattress and pillow covers was significantly higher in these families. However, 30% of families who saw an allergist reported no knowledge of any environmental control recommendations for dust mites. Less than half of the allergist families (48%) who were advised to use mattress encasements actually had encasements on their children's beds. CONCLUSIONS: The parents of dust mite-sensitive, asthmatic children who saw an allergist were more aware of dust mite allergen control recommendations and made more indoor environmental changes.

Nebulized beta2-agonist use in high-risk inner-city adults with asthma.

Nebulizer use has been linked to worse asthma outcomes, but the precise reason(s) for this relationship is not known. We assessed the frequency of nebulized beta2-agonist use in high-risk inner-city adults with asthma and compared asthma self-management practices according to nebulizer use in this population. This was a cross-sectional study conducted over 6 weeks from July to August 2000. A convenience sample (N=50) was recruited from an inner-city emergency department (ED). Adults (age > or = 18 years) were eligible if they had a physician diagnosis of acute asthma exacerbation. Data regarding asthma symptoms, acute care utilization, use of nebulized beta2-agonist for symptom relief, and indicators of asthma self-management (physician for asthma care, use of controller medications, current cigarette smoking, and substance use) were collected by an interviewer-administered survey. Nebulized beta2-agonist use was reported by 54.0% of patients during the 30 days before their ED visit. Nebulizer users reported more severe asthma symptoms (96.3% vs. 73.9% with moderate or severe persistent asthma, p=0.02) than nonusers. Nebulizer users were more likely to have a physician for asthma care (85.2% vs. 56.5%, p=0.02), have more frequent care from their physicians in the past 12 months (e.g., >3 visits: 59.3% vs. 30.4%, p=0.02), and notify their physician during their asthma exacerbation (39.1% vs. 7.7%, p=0.04). Compared with nonusers, nebulizer users reported better care across other indicators of care, though differences between groups were not significant. After accounting for symptom severity, results were largely unchanged. If these findings are confirmed in other studies with larger numbers of patients, we conclude that the relationship between nebulizer use and higher asthma morbidity largely represents preferential use of nebulizers by patients with more symptomatic disease.

The diagnostic pathway to sarcoidosis.

PURPOSE: To examine the time from the first physician visit to the diagnosis of sarcoidosis. HYPOTHESES: The time required to diagnose sarcoidosis is dependent on the initial symptoms, socioeconomic status, referral to a specialist, race, and severity of pulmonary involvement. METHODS: Patients were recruited from the Case Control Etiology of Sarcoidosis Study (ACCESS) and had biopsy-confirmed sarcoidosis. Subjects were asked to recall the date of onset of symptoms of sarcoidosis, their first physician visit, number of physician visits, and types of physicians seen. RESULTS: One hundred eighty-nine patients were enrolled. The diagnosis of sarcoidosis was made on the first physician visit in only 15.3% of cases. The presence of pulmonary symptoms was associated with prolonged time (> 6 months vs < or = 6 months, p = 0.02) until diagnosis, and the presence of skin symptoms with a shorter time (< or = 6 months vs > 6 months, p = 0.02) until diagnosis. Patients with pulmonary symptoms had more physician visits (mean +/- SEM) until the diagnosis was made compared to those without pulmonary symptoms (4.84 +/- 0.38 visits vs 3.15 +/- 0.24 visits, p = 0.0002). The mean baseline FEV(1) was greater in those diagnosed < or = 6 months from the first physician visit than those diagnosed > 6 months (87.3 +/- 1.52% predicted vs 81.2 +/- 2.5% predicted, p = 0.04). There was a significant delay in diagnosis (> 6 months vs < or = 6 months) from first physician visit with higher Scadding stages (stage 4 vs stage 2, or stage 3 vs stage 0 or 1, p = 0.04). CONCLUSIONS: The diagnosis of sarcoidosis is often delayed and seems to be more a factor of disease presentation than patient or physician characteristics. The presence of pulmonary symptoms or higher radiographic stages is associated with a prolonged time until diagnosis. The presence of skin symptoms is associated with less delay in diagnosis. It is likely that the delay in diagnosis of pulmonary sarcoidosis relates to the fact that pulmonary symptoms and parenchymal involvement are nonspecific and are often regarded as manifestations of other pulmonary diseases.

Caregiver-physician medication concordance and undertreatment of asthma among inner-city children.

OBJECTIVE: To assess the extent to which caregivers and their child's physician agree about the prescribed asthma medication regimen and evaluate factors associated with medication concordance. METHODS: A cross-sectional, descriptive survey was administered to 318 caregivers of inner-city children with asthma, aged 5 to 12 years, and their caregiver-identified primary care physician at elementary schools and participants' homes. Concordance between caregiver- and physician-reported controller medication prescription was measured. RESULTS: Only 42% of physicians and 32% of caregivers reported a controller medication prescription (78% agreement, kappa = 0.54; 95% confidence interval: 0.45-0.63) despite that 73% of the children were rated by their caregiver as currently experiencing persistent asthma symptoms. When the physician reported a controller prescription, 38% of the caregivers denied use of a controller. Having a course of oral steroids in the past year (chi(2) = 9.85) and positive caregiver beliefs toward asthma care (chi(2) = 18.40) were associated with caregiver-physician concordance. Multivariate analysis found that when caregivers had high Asthma Beliefs Scale summary scores versus low scores, they were almost 10 times as likely to be concordant with the physician (odds ratio: 9.76; 95% confidence interval: 2.85-33.46). CONCLUSIONS: Our data support previous reports of physician underprescribing of controller medication among inner-city children. However, even when prescribed by a physician, more than one third of caregivers did not report a controller prescription, and this discordance was related to caregivers' beliefs about treatment. Efforts to improve physician adherence to asthma guidelines will not result in proper treatment unless caregiver-physician communication about asthma therapy is improved.

Persistence of the effect of the Lung Health Study (LHS) smoking intervention over eleven years.

BACKGROUND: Research on the long-term persistence of effects of interventions aimed at smoking cessation is limited. This paper examined the quitting behavior of individuals who were randomized to a smoking cessation intervention (SI) or to usual care (UC), at a point approximately 11 years later. METHODS: The initial sample consisted of 5,887 adult smokers in 10 clinics who had evidence of airways obstruction. Two-thirds of the original participants were offered an intensive 12-week smoking cessation intervention. Of these, 4,517 were enrolled in the long-term follow-up study. RESULTS: Randomized group assignment was a strong predictor of smoking behavior after 11 years, in that 21.9% of SI participants and only 6.0% of UC participants maintained abstinence throughout the interval. Logistic regressions identified covariates associated with abstinence. A higher proportion of abstinence was observed in participants that had been assigned to SI (OR = 4.45), were older (OR = 1.11, increment 5 years), had more years of education (OR = 1.05), and fewer cigarettes/day at baseline (OR = 0.90, increment 10 cigarettes). CONCLUSIONS: Smokers exposed to an aggressive smoking intervention program and who sustain abstinence for a five-year period are very likely to still be abstinent after 11 years.
