    Use of Record Linkage to Examine Alcohol Use in Pregnancy

    ALCOHOLISM, Issue 4 2006
    Lucy Burns
    Background: To date, no population-level data have been published examining the obstetric and neonatal outcomes for women with an alcohol-related hospital admission during pregnancy compared with the general obstetric population. This information is critical to planning and implementing appropriate services. Methods: Antenatal and delivery admissions to New South Wales (NSW) hospitals from the NSW Inpatient Statistics Collection were linked to birth information from the NSW Midwives Data Collection over a 5-year period (1998,2002). Birth admissions were flagged as positive for maternal alcohol use where a birth admission or any pregnancy admission for that birth involved an alcohol-related International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Australian Modification (ICD-10-AM) code. Key demographic, obstetric, and neonatal variables were compared for births to mothers in the alcohol group with births where no alcohol-related ICD10-AM was recorded. Results: A total of 416,834 birth records were analyzed over a 5-year period (1998,2002). In this time, 342 of these were coded as positive for at least 1 alcohol-related ICD-10-AM diagnosis. Mothers in the alcohol group had a higher number of previous pregnancies, smoked more heavily, were not privately insured, and were more often indigenous. They also presented later on in their pregnancy to antenatal services and were more likely to arrive at hospital unbooked for delivery. Deliveries involved less epidural and local and more general anesthesia. Cesarean sections were more common to women in the alcohol group and were performed more often for intrauterine growth retardation. Neonates born to women in the alcohol group were smaller for gestational age, had lower Apgar scores at 5 minutes, and were admitted to special care nursery more often. Conclusions: This study shows that linked population-level administrative data provide a powerful new source of information for examining the maternal and neonatal outcomes associated with alcohol use in pregnancy.

    How Thailand has modified the section on mental disorders in the International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10),

    ASIA-PACIFIC PSYCHIATRY, Issue 2 2009
    Pichet Udomratn MD
    Abstract Introduction: In 2000, the Thai Ministry of Public Health appointed a taskforce to revise the International Statistical Classification of Diseases and Relate Health Problems 10th Revision (ICD-10) to make it more suitable for use in Thailand: the ICD-10 Thai Modification (ICD-10 TM). Methods: The Royal College of Psychiatrists of Thailand appointed psychiatrists from various hospitals to form a working group on this matter. The ICD-10 Australian Modification was used as an example and the ICD-10 Diagnostic Criteria for Research was used as a reference book. Results: The fourth and fifth characters added are the major modifications of the ICD-10 TM for the typing of an emotionally unstable personality disorder and treatment-resistant schizophrenia. However, we could not add any specific codes for patients dependent on amphetamine-type stimulant drugs. Discussion: The ICD-10 TM has now been widely used throughout the country since 2003, with informal feedback suggesting that it is useful. Further research needs to be conducted into its impact on clinical care in Thailand. [source]

    Effective coding in birth defects surveillance,

    BIRTH DEFECTS RESEARCH, Issue S1 2001
    Sonja A. Rasmussen
    Effective coding is critical to data collected by birth defects surveillance programs because subsequent use of the data depends on storage and retrieval of cases using codes. Hence, careful consideration needs to be given to the coding process. The primary goal of coding is to accurately, completely, and concisely represent infants with birth defects. Coding procedures need to accommodate the objectives of the surveillance program; for example, programs that focus on research may require different coding procedures from those that focus on linking infants to services. Several challenges exist in coding birth defects, including the need to distinguish infants with multiple defects and syndromes from those with isolated defects, and the need for strategies to code suspected defects for which confirmation is not available. Selection of a coding system by a birth defects surveillance program is central to the utility of the data collected. Most programs use a modification of the International Statistical Classification of Diseases and Related Health Problems-based (ICD) systems. This paper addresses ICD-based systems and the modifications used by many birth defects surveillance programs and presents examples of the problems in interpreting birth defects data because of inappropriate coding.
