| STUDY /RESEARCHERS | METHOD / PURPOSE | DATA SOURCE | DESCRIPTION |
|---|---|---|---|
| Injecting Drug Use (Mastro TD, et al. (1) |
Capture-recapture (Estimate population) |
Methadone treatment records; Police records. |
This study estimated the number of injection drug users infected with HIV in Bangkok in 1991. Two sample capture-recapture method was employed. |
| Heroin Users (Doscher ML, et al.(2)) |
Capture-recapture (Estimate size of population) |
Client oriented data acquisition process | The applications of general log-linear model and its special case, capture-recapture methods, were conducted to estimate the size of subpopulations of heroin users. Because of the heterogeneous capture probabilities among heroin users, a post hoc stratification design was used. |
| Methicillin use (Wittes J (3)) |
Multinomial capture-recapture (Estimate size of population) |
Reports form IV team; Reports from floor nurses; Hospital pharmacy; Medication sheets. |
A multinomial multiple recapture model was applied to estimate the patterns of utilization of methicillin in the Massachusetts General Hospital. Four sources were used to identify patients receiving methicillin. |
| Intravenous Drug Use (Drucker E, et al. (4)) |
Capture-recapture (Estimate size of population) |
Narcotics Registry; Previously identified addicts. |
The numbers of intravenous drug users lived in New York City from 1970 to 1974 were estimated by capture recapture method. |
| Injecting Drug Use (Frischer M, et al. (5)) |
Log-linear Model (Adjust prevalence) |
Treatment agencies; HIV-test scheme; Police sample. |
The prevalence of injecting drug use in Glasgow, Scotland, during 1989 was estimated by collecting information from three separate sources and using log-linear modeling technique. |
| Intravenous Drug Use (Perucci CA, et al (6)) |
Capture-recapture (Estimate population size) |
Drug addicts; AIDS cases among IVDUs. |
The annual average number of intravenous drug users aged 15-34 in Rome during a 2 year period (1987- 1988) was estimated by a 2-source capture-recapture method. |
| Opioid Dependence (Hartnoll R, et al. (7)) |
Capture-recapture (Estimate population) |
Two data source. | The total opioid-dependent population in Camden and Islington, United Kingdom in the period of 1970 to 1982 was estimated by comparing two data sources. |
| Injecting Drug Use (Frischer M, et al. (8)) |
Log-linear model (Estimate prevalence) |
HIV test register; Treatment agencies; Police records; Needle exchange. |
Log-linear modeling was applied to estimate the population prevalence of injecting drug use and infection with HIV among injection drug users in Glasgow, Scotland in 1990. |
| Heroin Abuse (Woodward JA, et al. (9)) |
Capture-recapture; Log-linear model (Estimate prevalence) |
Heroin-related admissions to federally funded treatment programs during 3 specific time intervals. | A log-linear-based capture-recapture method was simultaneously applied to 24 major metropolitan area in US to estimate the prevalence of heroin abuse. |
| Injecting Drug Use (Kehoe L, et al. (10)) |
Capture-recapture | Methadone service; The Bourke Street drug advisory service; The Albion Street Clinic. |
The number of injecting drug users residing within the Eastern Sydney Area Health Service were obtained by applying capture-recapture method. |
| Drug misuse (Hay G, McKeganey N(11)) |
Capture-recapture (Estimate prevalence) |
4 samples from both statutory and non-statutory data sources | Four data sources were used to estimate the prevalence of drug misuse in dundee between January 1990 and December 1994. The estimated unknown populatin was 1702, giving a total population of 2557 (prevalence 28.8 per 1000). |
| Strong analgesics use (Sorensen HT, et al(12)) |
Capture-Recapture (Estimate completeness) |
National Board of Health surveillance system; Danish National Health Service drug prescription register |
Two Danish population-based information systems on patients with strong analgesics use were evaluated. The capture-recapture method estimated that the completeness for the surveillance system was 96.9% and 97.5% for the National Health Service. |
| Drug misuse (Squires NF, et al (13)) |
Log-linear model (Estimate prevalence) |
Information from Drug Dependency Units; Infectious Diseases Unit; Arrest records |
Three-sample log-linear model was applied to determine the prevalence of opiate and cocaine misuse in the City of Liverpool in 1991. The estimated size of drug-using population was 2344 and a period prevalence was 5.2 per 1000. There was a negative interdependence between the police and Drug Dependency Unit databases. |
| Opiate addiction (Domingo-Salvany A, et al. (14)) |
Capture-recapture (Estimate prevalence) |
Hospital emergency rooms; treatment admissions; and heroin overdose deaths |
Log-linear model with three sources was used to estimate the prevalence of opiate addicts in Barcelona, Spain in 1989. The estimated prevalence for Barcelona in 1989 was between 8.5 and 9.9 opiate addicts per 1,000 residents aged 15-44 years. |
| Heroin users (Larson A, et al. (15)) |
Capture-recapture (Estimate prevalence) |
Seeking treatment/counselling; arrest on drug charge |
Two-sample capture-recapture was used to estimate the number of heroin users in a small Australian city in 1988-1989. The method produced a stable estimate of 1250 heroin users. |
