“…Capture-recapture methodology has been applied to correct for underascertainment in epidemiological studies of incidence, including some on the incidence of ALS [7,30], based on multiple sources for case ascertainment. This methodology requires, in order to obtain unbiased estimates of the number of cases, that some assumptions be satisfied, in particular the independence of the sources [33].…”

“…More recent studies, using multiple sources for case ascertainment and well-established diagnostic criteria, reported fairly uniform incidence estimates across populations in Europe and America, ranging from 1.5 to 2.9 cases per 100,000 person-years [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17]. A pooled crude incidence rate (IR) of 2.7 (95% confidence interval, 95% CI, 2.5-2.9) from 6 European registries was obtained [18].…”

Background: We conducted a retrospective population-based study to estimate the incidence of amyotrophic lateral sclerosis (ALS) in Friuli Venezia Giulia, Italy, from 2001 to 2009. Methods: Multiple sources were used for case ascertainment: Health databases, archives of the neurology departments and of the regional chapter of the Italian ALS Association. The diagnosis was validated through clinical documentation review. Crude and standardized incidence rates (IRs) per 100,000 person-years were calculated. Results: We identified 262 incident ALS cases, 50.4% men, 4.2% familial. Half of the patients had spinal onset (56.8% in men) and 25.2% bulbar (29% in women). Bulbar onset had a similar frequency in women (31.7%) and men (31.5%) aged 67 or above at diagnosis. The crude IR was 2.72 (95% confidence interval, 95% CI, 2.39-3.05) and the male:female ratio 1.08. The IR peaked in the 65-74 age group, with a second increase in men 85 years and older. The IR standardized to the 2001 Italian population was 2.38 (95% CI 2.13-2.63) and to the 2000 European population 2.58 (95% CI 2.34-2.81). Conclusions: This retrospective study found IRs of ALS in the range of Italian and European prospective population-based registries, suggesting an almost complete case ascertainment.

“…However, we did not account for type of onset (spinal vs. bulbar), age of onset, or severity of disease. Type of disease onset may be a factor in that spinal-onset is more diffi cult to diagnose [6] and therefore individuals with spinal-onset may be undercounted. However, even in the case of spinal-onset ALS, the course is relentlessly progressive and the extent of disability is severe.…”

“…Capture-recapture methods have been used extensively to adjust demographic parameter estimates for undercount in wildlife populations [2,3] . These methods also have high potential for epidemiological investigations involving human populations [4,5] and were applied in a recent study of the occurrence of ALS in France [6] . The challenge in using this approach is that case ascertainment studies involving human populations are complicated and are likely to violate one or more of the underlying statistical assumptions of capture-recapture modeling [5,7] .…”

Estimating the Occurrence of Amyotrophic Lateral Sclerosis among Gulf War (1990–1991) Veterans Using Capture-Recapture Methods

Objective: Using data from a recent report that indicated a 2-fold higher risk of amyotrophic lateral sclerosis (ALS) among veterans of the 1991 Gulf War, we applied capture-recapture methodology to estimate possible under-ascertainment of ALS cases among deployed and non-deployed military personnel who were on active duty during that war. Study Design and Setting: One of the most serious concerns facing field epidemiological investigations is that of case ascertainment bias, particularly when it is differential among the study groups. Capture-recapture methods, however, have promise as an approach to assessing the impact of case ascertainment bias in such studies. To overcome potential limitations of any one approach, three different estimation methods were used: log-linear models, sample coverage, and ecological models, to obtain a comprehensive view of under-ascertainment bias in these populations. Results: All three approaches indicated differential undercount of ALS cases with modest under-ascertainment likely to have occurred among non-deployed military personnel, but little under-ascertainment among the deployed. After correcting the rates for under-ascertainment, the age-adjusted risk of ALS remained elevated among military personnel who had been deployed to S.W. Asia during the 1991 Gulf War, confirming the earlier report. Conclusions: Capture-recapture methods are a useful approach to assessing the magnitude of case ascertainment bias in epidemiological studies from which ascertainment-adjusted estimates of rates and relative risks can be calculated.

“…It was originally used in ecology to determine the number of animals in a specified area (3,4). Recently, these methods have widely been used to estimate incidence and prevalence of health related outcomes (5)(6)(7)(8) and to evaluate the sensitivity of surveillance or registry systems (9)(10)(11). There are four assumptions on which this method is based: first, the population should be closed that means no change should occur in the size or structure of the population during study time; second, subjects should have equal probability of being captured in given sources; third, sources should act independently that means being captured by one source should not affect the probability of being captured by other sources; and four, there must be sufficient information to make a perfect linkage among sources (2,12,13).…”

Background: In many countries, disease registries are the main source of information that is necessary for planning and monitoring health-improving programs. In Iran, there is no unified registry system for deaths due to traffic accidents, so organizations that are involved in traffic accidents report different statistics. This study aimed at estimation of traffic accident mortality rate and completeness of death registries in Northern provinces of Iran from March 21, 2010 to March 20, 2011 using capture-recapture method. Methods: Attributes of all traffic accident victims including their first name, last name, age, sex, and date of death enrolled by traffic police department, legal medicine organization, and hospitals were used to count the number of cases that were captured by one, two or all the three aforementioned organizations. Then, different log-linear models proposed in the context of capture-recapture method were fitted to predict the number of cases missed by the three sources. Akaike information criterion (AIC) and Bayesian information criterion (BIC) were used as goodness of fit indices to identify preferred fitted models. Results: According to the prediction of the most fitted model, the total number of traffic accident deaths was 3857 of which, 727 cases were not captured by any of the responsible organizations. Mortality rate due to traffic accidents was estimated as 53.73 with 95% confidence interval (52.41 -55.15) per 100000 population of the three provinces. Coverage rates of legal medicine organization, hospitals, and traffic police department were 65.95%, 36.06%, and 16.85%, respectively. Conclusions: Incidence rate of fatal traffic accidents in Northern provinces of Iran is higher in comparison with other provinces. Besides, it seems that statistics reported by responsible organizations like legal medicine organization, traffic police department, and hospitals are underestimated, so it highlights the need for application of methods like capture-recapture to correct for this underestimation.
