ABSTRACT

Importance: Maternal mortality and severe maternal morbidity (SMM) are important focus areas in public health. Further understanding trends, health disparities, and risk factors for these adverse outcomes is vital to public health decision-making. Objective: To describe trends and risk factors for delivery-related maternal deaths and SMM in the United States. Design, Setting, and Participants: This is a retrospective cross-sectional study using data from a large, geographically diverse, all-payer hospital administrative database. Hospital discharges from January 2008 to December 2021 with any Medicare Severity Diagnosis Related Group, International Classification of Diseases, Ninth Revision, Clinical Modification, or International Classification of Diseases, Tenth Revision, Clinical Modification delivery diagnosis or procedure code were included. Data analysis took place from February 2021 to March 2023. Exposures: Year, quarter (Q), age, race and ethnicity, delivery method. Main Outcomes and Measures: Maternal mortality, SMM during delivery-related hospitalization. Results: Overall, 11 628 438 unique hospital discharges were analyzed, with a mean (SD) age of 28 (6) years. There were 437 579 (3.8%) Asian, 92 547 (0.8%) American Indian, 1 640 355 (14.1%) Black, 1 762 392 (15.2%) Hispanic, 83 189 (0.7%) Pacific Islander, and 6 194 139 (53.3%) White patients. Regression-adjusted maternal mortality per 100 000 discharges declined from 10.6 deaths in Q1 2008 to 4.6 deaths in Q4 2021. Mortality was significantly higher among patients with advanced maternal age (eg, age 35-44 years vs 25-34 years: adjusted odds ratio [aOR], 1.49; 95% CI, 1.22-1.84). Other significant risk factors for mortality included cesarean delivery, comorbid conditions, complications, and COVID-19 diagnosis (eg, cesarean delivery: aOR, 2.28; 95% CI, 1.87-2.79). The prevalence of any SMM increased from 146.8 per 10 000 discharges in Q1 of 2008 to 179.8 per 10 000 discharges in Q4 of 2021. SMM risk factors included age 24 years or younger or age 35 years or older, belonging to a racial or ethnic minority group, cesarean delivery, Medicaid insurance, and having 1 or more comorbidities (eg, age 10-19 years: aOR, 1.39; 95% CI, 1.36-1.42). Conclusions and Relevance: This cross-sectional study found that delivery-related mortality in US hospitals decreased for all racial and ethnic groups, age groups, and modes of delivery during 2008 to 2021, likely demonstrating the impact of national strategies focused on improving maternal quality of care provided during delivery-related hospitalizations. SMM prevalence increased for all patients, with higher rates for racial and ethnic minority patients of any age. Advanced maternal age, racial or ethnic minority group status, cesarean delivery, and comorbidities were associated with higher odds of mortality and SMM.

ABSTRACT

Reducing emergency room (ER) use may indicate the improved quality of patient care at index hospitalization. The aim of this study is to determine whether the use of near-infrared fluorescence (NIRF) imaging with indocyanine green (ICG) during coronary artery bypass grafting (CABG) surgery is associated with a lowered 90-day all-cause ER use. Materials and Methods: This retrospective cohort study included adult patients with inpatient hospitalizations between January 2016 and June 2020 for an isolated CABG procedure at a US hospital. Propensity score matching was used to create matched cohorts to address the differences in patient, payer type, hospital, and clinical characteristics. A multivariable regression analysis was conducted to determine the association of NIRF imaging with ICG on ER use within 90 days of discharge after controlling for patient, payer type, hospital, and clinical covariates. Results: In total, 230 506 adult patients underwent an isolated CABG procedure. Less than 1% (n=1965) were assessed with NIRF imaging using ICG. There were differences in patient demographic and hospital characteristics between the treatment group (i.e. NIRF with ICG) and the comparison group (i.e. no NIRF with ICG). After controlling for covariates, a statistically significant lower 90-day all-cause ER use was documented among the treatment group (adjusted odds ratio=0.84, 95% confidence interval=0.73-0.96, P<0.009). Reasons associated with ER use were similar between the two groups. Conclusion: Routine intraoperative graft patency assessment with NIRF imaging using ICG may help to improve a patient's care experience and reduce subsequent resource utilization. Intraoperative graft patency assessment with NIRF imaging using ICG is associated with a 90-day all-cause ER use reduction among CABG patients. Further studies are needed to compare the ER usage among centers that used this technique versus those that did not to determine if associated reductions in ER use are a center or technique-specific phenomenon.

ABSTRACT

Aim: This retrospective, observational study assessed healthcare resource utilization (HCRU) and costs for newly diagnosed acute myeloid leukemia (AML) patients receiving intensive induction chemotherapy. Materials & methods: Adult AML patients with inpatient hospitalization or hospital-based outpatient visit receiving intensive induction chemotherapy (CPX-351 or 7 + 3 treatments) were identified from the Premier Healthcare Database (US). Results: All 642 patients had inpatient hospitalizations (median number = 2; median length of stay = 16 days); 22.4% had an ICU admission. Median total outpatient hospital cost was US$2904 per patient, inpatient hospital cost was $83,440 per patient, and ICU cost was $16,550 per patient. Discussion: In the US hospital setting, substantial HCRU and costs associated with intensive induction chemotherapy for AML were driven by inpatient hospitalizations.

ABSTRACT

Purpose: To assess costs and healthcare resource utilization (HCRU) associated with the use of idarucizumab for the reversal of dabigatran and andexanet alfa for the reversal of direct oral Factor Xa inhibitors. Methods: This retrospective study utilizing Premier Healthcare Database (PHD) included patients aged ≥18 years on direct oral anticoagulants (DOACs) who experienced life-threatening bleeds, discharged from the hospital during 5/1/2018-6/30/2019, and received idarucizumab or andexanet alfa. Inverse of treatment probability weighting (IPTW) method was used to balance patient and clinical characteristics between treatment cohorts. Results: Idarucizumab patients were older than andexanet alfa patients (median age 81 vs 77 years; p < 0.001), and less likely to experience intracranial hemorrhage (ICH) (37.1%vs 73.8%; p = 0.001). After IPTW adjustment, idarucizumab patients incurred lower mean total hospital costs ($30,413 ± $33,028 vs $44,477 ± $30,036; p < 0.001),and mean intensive care unit (ICU) cost ($25,114 ± $30,433 vs $43,484 ± $29,335; p < 0.001). Conclusions: Anticoagulant reversal therapy with idarucizumab was associated with significantly lower adjusted mean total hospital and ICU costs compared with andexanet alfa. However, a higher prevalence of ICH bleeds was noted in the andexanet alfa group. Trial Registration: Not applicable.

ABSTRACT

BACKGROUND: The objective of the study was to describe the healthcare resource utilization (HCRU) and associated costs with hospitalized patients receiving specific versus non-specific oral anticoagulation reversal therapy for life-threatening bleeds and emergency surgeries or urgent procedures. METHODS: This retrospective observational study using the Premier Healthcare Database included adult patients aged ≥ 18 years treated with idarucizumab (IDA) or 3- or 4-factor prothrombin complex concentrates (PCC) to reverse the effects of dabigatran or warfarin, respectively, between October 2015 and February 2018. RESULTS: Median ages for IDA (n = 1,232) and PCC (n = 4,939) patients were 78 and 74 years (P < 0.001), respectively. IDA patients had lower bleeding and stroke risk assessment scores (HAS-BLED; P < 0.001 and CHA2DS2-VASc; P = 0.014) and lower prevalence of comorbidities compared with PCC patients. Median hospital length of stay was 6 and 7 days for patients who received IDA or PCC (P < 0.001), respectively. The percentage of patients with an intensive care unit (ICU) admission was lower for IDA patients compared with PCC patients (61.3% vs. 68.7%; P < 0.001). Median total costs per hospitalization were $19,357 for IDA patients and $26,920 for PCC patients (P < 0.001). Median costs per hospitalization for IDA and PCC treatment were $3,277 and $4,424, respectively. When HCRU and costs were examined by cause of reversal and type of bleed, similar trends in hospitalized costs emerged for IDA compared with PCC treatment. CONCLUSIONS: This analysis revealed lower HCRU and total hospital costs in patients administered IDA compared with PCC for reversal of oral anticoagulation, though differences in population characteristics and bleeding events were observed that may have contributed to these findings.

ABSTRACT

PURPOSE: CPX-351 is dual-drug liposomal encapsulation of daunorubicin and cytarabine at a fixed synergistic 1:5 molar ratio. This study determined current real-world use of CPX-351 versus conventional 7+3 (cytarabine+daunorubicin) therapy and evaluated hospital length of stay (LOS) and supportive care utilization in t-AML and AML-MRC. PATIENTS AND METHODS: This retrospective, observational study utilized the Premier Healthcare Database and included patients who were aged ≥18 years with t-AML or AML-MRC and treated with CPX-351 or 7+3 between August 1, 2017 and February 28, 2019. All patients treated with 7+3 were required to be eligible for CPX-351 based on its FDA-approved indication. Outcome variables were annualized and adjusted for patient, hospital, and clinical confounding factors. The primary outcome was inpatient LOS. Secondary outcomes included use of blood products and use of anti-infectives. RESULTS: The study included 195 qualifying patients treated with CPX-351 and 160 patients treated with 7+3 who were eligible for CPX-351. Approximately one-third of the patients treated with CPX-351 were administered therapy in a hospital-based outpatient setting, and all patients treated with 7+3 received it in the inpatient setting. The regression-adjusted annualized inpatient LOS was shorter with CPX-351 than 7+3 (mean of 183.7 vs 197.1 days, p<0.001). The difference in mean-adjusted LOS was most pronounced for t-AML, with a mean-adjusted LOS of 168.9 versus 192.5 days for CPX-351 versus 7+3, respectively (nominal p<0.001). Supportive care utilization, including the number of administrations of red blood cells, the number of administrations of platelets, and the number of days on anti-infectives, was similar between treatment groups. CONCLUSION: CPX-351 was associated with a shorter inpatient LOS than 7+3. Supportive care use, including blood products and anti-infectives, was similar for CPX-351 and 7+3. These findings suggest CPX-351 conveys resource advantages over 7+3 in patients with newly diagnosed t-AML and AML-MRC.

ABSTRACT

AIMS: Sinusoidal obstruction syndrome (SOS) is a life-threatening complication of hematopoietic stem cell transplantation (HSCT) associated with significant morbidity and mortality. Healthcare utilization, costs, and mortality were assessed in HSCT patients diagnosed with SOS, with and without multi-organ dysfunction (MOD). MATERIALS AND METHODS: This retrospective observational study identified real-world patients undergoing HSCT between January 1, 2009 and May 31, 2014 using the Premier Healthcare Database. In absence of a formal ICD-9-CM diagnostic code, SOS patients were identified using a pre-specified definition adapted from Baltimore and Seattle criteria and clinical practice. Severe SOS (SOS/MOD) and non-severe SOS (SOS/no-MOD) were classified according to clinical evidence for MOD in the database. RESULTS: Of the 5,418 patients with a discharge diagnosis of HSCT, 291 had SOS, with 134 categorized as SOS/MOD and 157 as SOS/no-MOD. The remaining 5,127 patients had HSCT without SOS. Overall SOS incidence was 5.4%, with 46% having evidence of MOD. Distribution of age, gender, and race were similar between the SOS cohorts and non-SOS patients. After controlling for hospital profile and admission characteristics, demographics, and clinical characteristics, the adjusted mean LOS was 31.0 days in SOS/MOD compared to 23.9 days in the non-SOS cohort (medians = 26.9 days vs 20.8 days, p < .001). The adjusted mean cost of SOS/MOD patients was $140,653, which was $41,702 higher than the non-SOS cohort (medians = $105,749 vs $74,395, p < .001). An almost 6-fold increased odds of inpatient mortality was associated with SOS/MOD compared to the non-SOS cohort (odds ratio = 5.88; 95% CI = 3.45-10.33). LIMITATIONS: Limitations of retrospective observational studies apply, since the study was not randomized. Definition for SOS was based on ICD-9 diagnosis codes from a hospital administrative database and reliant on completeness and accuracy of coding. CONCLUSIONS: Analysis of real-world data shows that SOS/MOD is associated with significant increases in healthcare utilization, costs, and inpatient mortality.

ABSTRACT

BACKGROUND: There is a growing use of procalcitonin (PCT) to facilitate the diagnosis and management of severe sepsis. We investigated the impact of one to two PCT determinations on ICU day 1 on health-care utilization and cost in a large research database. METHODS: A retrospective, propensity score-matched multivariable analysis was performed on the Premier Healthcare Database for patients admitted to the ICU with one to two PCT evaluations on day 1 of ICU admission vs patients who did not have PCT testing. RESULTS: A total of 33,569 PCT-managed patients were compared with 98,543 propensity score-matched non-PCT patients. In multivariable regression analysis, PCT utilization was associated with significantly decreased total length of stay (11.6 days [95% CI, 11.4 to 11.7] vs 12.7 days [95% CI, 12.6 to 12.8]; 95% CI for difference, 1 to 1.3; P < .001) and ICU length of stay (5.1 days [95% CI, 5.1 to 5.2] vs 5.3 days [95% CI, 5.3 to 5.4]; 95% CI for difference, 0.1 to 0.3; P < .03), and lower hospital costs ($30,454 [95% CI, 29,968 to 31,033] vs $33,213 [95% CI, 32,964 to 33,556); 95% CI for difference, 2,159 to 3,321; P < .001). There was significantly less total antibiotic exposure (16.2 days [95% CI, 16.1 to 16.5] vs 16.9 days [95% CI, 16.8 to 17.1]; 95% CI for difference, -0.9 to 0.4; P = .006) in PCT-managed patients. Patients in the PCT group were more likely to be discharged to home (44.1% [95% CI, 43.7 to 44.6] vs 41.3% [95% CI, 41 to 41.6]; 95% CI for difference, 2.3 to 3.3; P = .006). Mortality was not different in an analysis including the 96% of patients who had an independent measure of mortality risk available (19.1% [95% CI, 18.7 to 19.4] vs 19.1% [95% CI, 18.9 to 19.3]; 95% CI for difference, -0.5 to 0.4; P = .93). CONCLUSIONS: Use of PCT testing on the first day of ICU admission was associated with significantly lower hospital and ICU lengths of stay, as well as decreased total, ICU, and pharmacy cost of care. Further elucidation of clinical outcomes requires additional data.

ABSTRACT

PURPOSE: Results of a study of bleeding events and other inhospital outcomes with the use of clopidogrel versus prasugrel in patients with acute coronary syndrome (ACS) managed with percutaneous coronary intervention (PCI) are reported. METHODS: Demographic and clinical data on adults hospitalized for ACS, managed with PCI, and treated with clopidogrel or prasugrel during a two-year period were extracted from a large hospital claims database. Bleeding rates, hospital length of stay (LOS), and total hospital costs during the index hospitalization were evaluated. RESULTS: The study sample consisted of 75,297 patients who received clopidogrel and 9,477 who received prasugrel. The unadjusted bleeding rates were 5.7% with clopidogrel use and 3.2% with prasugrel use (p < 0.0001). After propensity score stratification to adjust for selection bias, rates of bleeding events were not significantly different between clopidogrel- and prasugrel-treated patients (odds ratio, 0.90; 95% confidence interval [CI], 0.80-1.02; p = 0.0949). The adjusted mean ± S.D. hospital LOS was 0.22 day lower (95% CI, 0.15-0.28; p < 0.001) with the use of prasugrel versus clopidogrel, and adjusted total mean hospital costs were $375 less for prasugrel-treated patients (p = 0.003). CONCLUSION: After adjustments for demographic and clinical characteristics, rates of inhospital bleeding in patients who received prasugrel and those who received clopidogrel were not significantly different. The adjusted analyses showed that the mean hospital LOS was shorter and total mean hospital costs were lower for patients treated with prasugrel.

ABSTRACT

BACKGROUND: Community-acquired bacterial pneumonia (CABP) is a leading cause of morbidity and mortality especially in hospitalized patients. In place of clinical end points traditionally used to evaluate antimicrobial efficacy for its treatment, Food and Drug Administration guidelines now require all registration trials to assess clinical response at day 4. The primary objective of this study was to assess health outcomes (length of stay [LOS] and hospital charges) between responders and nonresponders at this time point. METHODS: The Premier database was used to identify adult patients from 4 participating hospitals with a principal diagnosis of CABP (International Classification of Diseases, Ninth Revision, Clinical Modification, codes 481, 482.0, 483.8, 484.3, 484.5, 485, 486, or 487.0) hospitalized between July 1, 2010, and June 30, 2011. Only non-intensive care unit patients with hospital stays exceeding 2 days and receiving intravenous antibiotic agents within 24 hours of admission were included. After institutional review board approvals, a retrospective chart review extracted data for patient demographics, clinical efficacy variables at day 4, LOS, and total hospital charges. Data analysis included multivariable gamma regression models to control for patient demographics and clinical differences between responders and nonresponders. RESULTS: A total of 666 patients met study the criteria. Mean (SD) age was 70.7 (17.9) years, and 42.5% were males. Among these patients, 277 (41.6%) achieved clinical response by day 4 of initial antibiotic therapy. The unadjusted mean (SD) LOS was 6.3 (2.8) days for responders and 7.4 (5.6) days for nonresponders (P = 0.0009). Respective unadjusted total hospital charges were $22,827 (SD, $17,724) and $26,403 ($36,882) (P = 0.0031). Adjusted for demographics and clinical factors, nonresponders compared with responders had an increased LOS of 0.9 days (8.4 vs 7.5 days; P = 0.0008), resulting in associated charges of approximately $2500 ($34,139 vs $36,629; P = 0.0768). CONCLUSIONS: In this real-world chart study, less than half of hospitalized patients with CABP achieved clinical response at day 4 of initial intravenous antibiotic therapy. The observed clinical response was associated with a significantly shorter hospital stay and trended toward lower total hospital charges. These findings corroborate the Food and Drug Administration guidance for assessing antimicrobial therapy at day 4 because responder is associated with improved health outcomes.

ABSTRACT

OBJECTIVES: To compare 30 and 90 day real-world acute myocardial infarction (AMI) and bleeding related rehospitalization rates in acute coronary syndrome (ACS) patients receiving percutaneous coronary intervention (PCI; ACS-PCI) treated with clopidogrel or prasugrel. RESEARCH DESIGN AND METHODS: Using the Premier hospital database, ACS-PCI patients receiving a drug-eluting (DES) or bare-metal (BMS) stent and clopidogrel or prasugrel from July 2009 to June 2011 were analyzed. Patients were included based on the prasugrel US prescribing information (USPI), excluding patients with a history of transient ischemic attack/stroke and patients ≥75 years without diabetes or prior MI. The primary endpoint was 30 day adjusted AMI rehospitalization rate. Secondary endpoints included 90 day AMI and 30 and 90 day bleeding-related rehospitalization rates. Treatment comparisons were adjusted using propensity score stratification. RESULTS: At the index event, prasugrel patients (N = 9404) differed from clopidogrel patients (N = 74,163) by having a lower risk of comorbid conditions associated with bleeding, being more likely younger and male, having ST-elevation MI and receiving a DES. For clopidogrel and prasugrel, respectively, the observed AMI-related rehospitalization rates were 4.7% and 3.9% at 30 days (p < 0.0001) and 6.3% and 5.1% at 90 days (p < 0.0001). After adjustment, prasugrel was associated with ∼10% lower odds of AMI-related rehospitalization (30 days: OR = 0.892 [95% CI: 0.798, 0.998]; 90 days, OR = 0.901 [95% CI: 0.817, 0.994]). Adjusted bleeding-related rehospitalization rates were similar to each other (OR = 1.035 at 30 days [95% CI: 0.765, 1.399]; OR = 0.922 at 90 days [95% CI: 0.725, 1.172]). STUDY LIMITATIONS: Treatment adherence was not assessed. Bleeding events not resulting in a hospitalization (e.g. office, outpatient, or emergency room visits), deaths outside the hospital, or readmissions to a hospital outside of the Premier alliance were not captured in the database. CONCLUSIONS: The different patient characteristics between prasugrel- and clopidogrel-treated patients suggest physicians are more selective in choosing patients for prasugrel than recommended in the prasugrel USPI. However, after adjustment for these differences, 30 and 90 day AMI rehospitalization rates were lower for prasugrel-treated patients compared to clopidogrel-treated patients, with no difference in adjusted bleeding-related rehospitalization rates.

ABSTRACT

BACKGROUND: Central venous catheter (CVC) occlusion is common, affecting 30% of all CVCs. OBJECTIVE: To compare length of stay (LOS), costs, and readmissions associated with the use of alteplase to clear catheter blockage to outcomes associated with catheter replacement. DESIGN: Retrospective observational study utilizing a large hospital database. PARTICIPANTS: Hospitalized patients treated for catheter occlusion from January 2006 to December 2011. MAIN MEASURES: Univariate analyses of patient characteristics and treatment patterns and multivariable regression analyses of postocclusion hospital costs, LOS, and 30- and 90-day readmissions were conducted. KEY RESULTS: We included 34,579 patients treated for a CVC occlusion by replacement (N=1028) or by alteplase (2 mg) administration (N=33,551). Patients receiving alteplase were somewhat younger than those having catheter replacement (60 ± 19 vs 62 ± 20 years old, P=0.0002). After adjusting for patient and hospital factors via regression modeling, average daily postocclusion costs were $317 lower for alteplase recipients than for catheter replacement patients (95% confidence interval [CI]: 238.22-392.24; P<0.0001). Adjusted total postocclusion costs were $1419 lower for alteplase recipients versus patients receiving catheter replacement (95% CI: 307.27-2458.12; P=0.0121). Postocclusion operating room/surgery, radiology, and supply costs were significantly lower for alteplase recipients (P<0.001). Average adjusted postocclusion LOS was similar for both groups (P>0.05). Odds of readmission were not significantly different at 30 or 90 days. CONCLUSIONS: Among patients treated for an occluded CVC, alteplase-treated patients had lower daily and total postocclusion costs than patients receiving catheter replacement. Cost differences were mainly driven by lower operating room/surgery, radiology, and supplier costs.

ABSTRACT

We previously established that Babor Type A "lower-risk/severity" alcoholics (n = 55) had better treatment response to fourteen weeks of sertraline (200 mg/day) than placebo, a finding not present for Type B "higher-risk/severity" alcoholics (n = 45). This exploratory study extended these results by examining the original sample for gender differences in response to sertraline pharmacotherapy. Type A alcoholic men, but not Type A alcoholic women, had consistently better outcomes with sertraline compared to placebo on several common drinking measures: time to relapse, days drinking, days drinking heavily, drinks per drinking day, and number of those continually abstinent. There were no significant differences in drinking with sertraline compared to placebo in Type B alcoholic men or women.

ABSTRACT

BACKGROUND: Evidence supporting the use of serotonergic medications for the treatment of alcohol dependence is available from studies where pharmacotherapy targeted specific alcoholic subtypes. We previously established with Babor's alcohol typology that type A "lower risk/severity" alcoholics (n = 55) had better treatment response to 14 weeks of sertraline (200 mg/day) than placebo, and this was not found for type B "higher risk/severity" alcoholics (n = 45). The purpose of this study was to assess in this original study group whether treatment gains in the type A alcoholics were maintained or whether treatment outcomes changed for the type B alcoholics after discontinuing pharmacotherapy. METHODS: After the end of a 3-month course of 200 mg/day sertraline, the subjects were interviewed at several time points about their alcohol drinking, if any, using the timeline follow-back method. For 90% of the original study group, mixed effects and generalized estimating equation models were used to compare monthly drinking amounts over a 6-month posttreatment period with drinking amounts in the last month of treatment. RESULTS: We found that type A alcoholics who had been treated with sertraline, in contrast to placebo, maintained the good outcomes they had achieved during treatment for at least 6 months after pharmacotherapy. We found that type B alcoholics who had been treated with sertraline, in contrast to placebo, continued to show no advantage for pharmacotherapy in the 6 months after completing treatment. In addition, heavy drinking in type B alcoholics increased over the 6 months postpharmacotherapy in those initially treated with sertraline compared with placebo. CONCLUSIONS: These data support the importance of considering alcohol subtype when pharmacologically treating alcohol dependence.

ABSTRACT

This study compared the effects of alcohol and cocaine dependence severity on the outcome of outpatient detoxification from alcohol and cocaine. Subjects included 84 subjects with both alcohol and cocaine dependence admitted for outpatient detoxification. Fifty-three of the 84 subjects (63%) completed detoxification. Baseline cocaine use, cocaine craving, and cocaine withdrawal symptoms predicted detoxification outcome, whereas alcohol use, alcohol craving, and alcohol withdrawal symptoms did not. Among cocaine- and alcohol-dependent subjects, cocaine dependence severity appears to be a more important predictor of detoxification success than alcohol dependence severity.

ABSTRACT

This study evaluated for 152 patients the relationship between their attitudes toward treatment and session attendance in pharmacotherapy research trials aimed at treating alcohol dependence. The study included a new, 50-item, patient-administered measure of attitudes, Treatment Research Experiences and Attitudes Task (TREAT), which is comprised of ten items from each of five attitudinal dimensions typically associated with treatment adherence: treatment setting, taking medication, social support, medical professional, and intrinsic patient factors. Patients attending 80% or more clinical sessions scored higher, i.e., were more favorable on four of five of attitudinal dimensions. Thus, patient attitudes toward treatment may be useful in identifying areas that limit or improve treatment attendance.

ABSTRACT

This report evaluates the validity of a new method for verifying self-reported smoking status in patients presenting for pulmonary medicine treatment. A prospective comparison was made between self-reports of smoking status and a new semiquantitative, enzyme-linked, immunosorbent assay-based method testing for the presence of a prime nicotine metabolite, cotinine. Results were validated by gas chromatography/mass spectrometry. Data were collected in an urban, academic, tertiary health care setting. The study included 76 consecutive new patients presenting to participating clinical practices at the Pulmonology or Thoracic Surgery Services. Before taking a smoking history, patients were informed that their urine would be tested onsite for the presence of nicotine using a new method, the NicoMeter, for determining tobacco product exposure, followed by more standard laboratory testing. The level of agreement between the biochemical measurement types was excellent, kappa = 0.777. The new biochemical measurement type used was easy to use. Self-reported smoking status corresponded closely to biochemical testing. However, there was a 5.3-9.5% misclassification of smoking status among the group studied, depending upon the measurement type used. Among 32 lung cancer patients, 15.6%, most likely misrepresented their current smoking status. The NicoMeter appears to be a valid and useful method for confirming self-reported smoking status. Lung cancer patients had a higher rate of inaccurate nonsmoking compared with patients with nonmalignant pulmonary disease. The findings have implications for investigators who accept self-reported smoking status without biochemical verification.
