Furthermore, differences in phenotypes between NTM-PD patients in Europe and North America ( 12) suggest that death rates might differ substantially between these regions. One population-based study of survival in NTM-PD patients has been reported, but it did not include controls without NTM, so NTM-attributable death could not be determined ( 11). Studies from individual clinical programs have identified prognostic factors ( 7– 10), but estimates of survival are undoubtedly affected by referral bias and therefore cannot be generalized to all NTM-PD patients. At the population level, patients with NTM-PD have been poorly characterized in general, and their survival is not well studied.We disregarded Mycobacterium gordonae isolates and excluded persons with prior (1998–2000) NTM isolation. One positive sputum sample defined NTM-PI, whereas >1 positive sputum sample for the same species or 1 positive bronchoscopic or biopsy specimen defined NTM-PD. Additional details about the data sources and methods are provided in the Technical Appendix.Using microbiological criteria from current guidelines ( 5), we defined 2 mutually exclusive groups. The responsible institutional review committees approved this study.Their population-matched unexposed controls). Primary analyses compared survival of propensity score–matched exposed with unexposed persons, for each species–condition group (e.g., patients with MAC NTM-PD vs. Index date was date of first positive culture for exposed patients and was randomly assigned to potential unexposed controls by using a random number generator.We characterized our cohort by demographics, underlying conditions, and healthcare utilization. We sought to match each patient with NTM (exposed person) to an Ontario resident without NTM (unexposed control) who shared the age (years), sex, and index date (± 90 days), and had a propensity score value within 0.2 × SD of the exposed patient ( 15). Kansasii, and other, according to the condition-states NTM-PI and NTM-PD.
![]() Publisher 2017 Install CrossOver On![]() For survival analyses of single-species versus multispecies NTM-PD, we addressed immortal time bias (time to second species infection inflating survival of patients with multispecies NTM-PD) using status of single-species versus multispecies NTM as a time-varying covariate. Multispecies NTM-PD) included all Ontario residents with NTM species–conditions of interest and were adjusted for age, sex, and covariates used to characterize the cohort in our study. NTM-PI and single-species vs. Comparisons between groups that were not propensity-matched (NTM-PD vs. These covariates were explored for inclusion by using a Hosmer-Lemeshow approach (inclusion if >10% effect on point estimate ) none were retained. 64 years, p<0.001 NTM-PD, median 72 vs. Compared with matched patients, patients who could not be matched to unexposed controls were older (NTM-PI, median 74 vs. Propensity score matching was successful for 9,967 (91%) NTM-PI patients and 8,469 (87%) NTM-PD patients. In addition, unmatched patients had substantially lower survival than did matched patients at 1 year (76.1% vs. 9.8, p<0.001) ( Technical Appendix Table 1). 8.9, p<0.001 NTM-PD 12.4 vs. Excel for mac automatically auto enter with return keyCombining all species, the sexes were similarly represented for NTM-PD and NTM-PI. Abscessus was seen more commonly in female patients and the other NTM species were seen more commonly in male patients ( Table 1, 2 Technical Appendix Tables 2– 4). 65.4%) for all NTM-PD.We observed small differences in sex distribution by species, whereby NTM-PD with MAC and M. 85.7%) and 5 years (47.7% vs. 76.0%) for all NTM-PI and at 1 year (75.3% vs. Abscessus and lowest for patients with M. There is a statistically significant.Kaplan-Meier plots for any NTM (NTM-PD or NTM-PI), including both matched and unmatched patients, by species group, revealed apparently distinct death rates survival was highest for patients with M. Curve comprises all matched and unmatched patients identified during the study period. Kaplan-Meier survival curves for any pulmonary NTM isolation, by species group, Ontario, Canada, 2001–2013. Covariates were generally balanced between the matched groups.Figure. Patients had a high prevalence of underlying conditions by adjusted clinical group numbers (7.3–10.1), including asthma (25%–36%), chronic obstructive pulmonary disease (COPD 25%–52%), diabetes (12%–24%), chronic kidney disease (3%–8%), and gastresophageal reflux disease (11%–20%), ranging by species–condition groups. Xenopi individually ( Table 4). NTM-PI) had higher death rates for all species combined, as well as for MAC and M. In adjusted comparisons, patients with NTM-PD (vs. Fortuitum disease (HR 1.25, 95% CI 0.96–1.63) were not statistically significant.As illustrated by the standardized mortality ratios, adjusted for sex and 5-year age stratum, death rates were increased above expected for the Ontario general population for all groups compared ( Table 4). Abscessus isolation (HR 1.39, 95% CI 0.94–2.07), and M. Hazard ratios (HRs) for death were elevated for all species–condition groups, but those for M. Xenopi (n = 354) versus either species alone (n = 8,059) (HR 1.23, 95% CI 1.04–1.45). Death rates also were higher for the subgroup of MAC plus M. Compared with the 9,061 patients who had single-species NTM-PD, the 620 patients with multispecies NTM-PD (any combination of NTM species) had higher rates of death (HR 1.19, 95% CI 1.04–1.34). Xenopi was the only species associated with a significantly higher death rate. Compared with MAC (reference species group), M. In the multivariable analysis of baseline factors for association with death among all patients with incident NTM-PD (matched and unmatched patients), increasing age, male sex, low income, and underlying conditions were all associated with reduced survival ( Table 5).
