Multicenter Survey of Physicians' Perception of Interpretative Commenting and Reflective Testing in Nigeria.

BACKGROUND: Interpretative commenting (IC) and reflective testing have recently generated interest because of their potential for adding value to Clinical laboratory testing. Physicians' perception to this post-testing service in Nigeria is unknown. This study examined the practices and physician's disposition regarding IC and reflective testing. METHODS: This cross-sectional study was conducted among 232 doctors working in public and private hospitals across eight purposively selected states in Nigeria. Doctors who have worked and/or currently working in a health facility within their state of residence and who consented to participating in this survey were given a structured questionnaire to fill and return. RESULTS: Paper-based reporting (213; 91.8%) was the most commonly practiced reporting method. One hundred and thirty-three (57.4%) doctors responded that interpretative comments were added to laboratory reports. "Free-handed text" (85/133; 63.9%) was the most commonly practiced form of IC; 184/232 (79.3%) and 166/232 (71.6%) doctors respectively considered comments on "potential implication of results" and "suggestions on further investigation" as the most "helpful" aspect of IC. Also, 192/232 (82.7%) doctors strongly agreed/agreed that IC influences patient's management. Only 125 (53.7%) doctors responded that they welcomed reflective testing. Concerns about cost implications (68/107;63.6%) and delays in release of result (48/107; 44.9%) were among reasons for not supporting reflective testing. CONCLUSION: Nigerian doctors generally have a positive disposition towards addition of interpretative comments but less so concerning reflective testing. However, challenges such as lack of LIS, EQA schemes for IC and gaps in physicians' education should be addressed to improve this aspect of laboratory services in Nigeria.

Dyslipidemia in ART-Naive HIV-Infected Persons in Nigeria--Implications for Care.

AIMS: This study aimed to describe the prevalence and pattern of lipid abnormalities among antiretroviral therapy (ART)-naive HIV patients, understand if there is any relationship to virologic and immunologic status, and discuss the implications for care. METHODS: This was a cross-sectional study in which baseline demographic, clinical, and laboratory data of all ART-naive HIV-infected individuals recruited into the adult ARV clinic, University College Hospital, Ibadan, between January and December 2006, were analyzed. RESULTS: In total, 1316 ART-naive HIV-infected persons were recruited in the period. Females subjects and participants aged ≦35 years accounted for 67.1% and 57.7% of all participants, respectively. At least 1 abnormal lipid fraction was seen in 73.3% of participants. It was observed that in 11.5% participants the total cholesterol (TC) was ≧5.2 mmol/L, in 2.7% the low-density lipoprotein cholesterol (LDL)-C was >4.1 mmol/L in 56.5% the high-density lipoprotein cholesterol (HDL)-C was <1.0 mmol/L, and in 27.6% the triglyceride (TG) was >1.7 mmol/L. The TC, LDL-C, and HDL-C were all significantly positively correlated with CD4 counts and negatively correlated with viral load. On the contrary, the TG levels were negatively correlated with CD4 counts and positively correlated with viral load. Multivariate linear analysis showed a significant relationship between all the lipid parameters and viral load. CD4 counts were only significantly associated with TC. CONCLUSIONS: A significant burden of dyslipidemia exists among ART-naive HIV-infected persons. Low HDL-C was the most frequently observed abnormality. The abnormalities related more with viral load levels than with CD4 counts. Dyslipidemia screening should be done in ART-naive HIV-infected persons. Simple healthy lifestyle changes should be emphasized, with other care given to those with the disorder.

Oral glucose tolerance testing outcomes among women at high risk for gestational diabetes mellitus.

AIMS: This study aimed to determine the prevalence and relationships with known risk factors of gestational diabetes mellitus (GDM) at University College Hospital, Ibadan, Nigeria. METHODS: Records of all women referred for oral glucose tolerance testing at the metabolic research unit of the Hospital over a 2 year period were reviewed. Diagnosis of GDM was made in accordance with WHO criteria. GDM diagnosis was classified as early and late based on a gestational age <24 weeks and >24 weeks respectively. Body mass index (BMI) measurements were performed for women who presented in the first trimester. Various statistical tools including student t test and Pearson's coefficient of correlation were used. RESULTS: A total of 765 records were reviewed. The crude prevalence rate was 13.9%. The prevalence rate among women in the first trimester was highest at 17.4% although most of the diagnoses were made in the third trimester (55.7%). A positive family history and a family history of GDM were associated significantly with a higher fasting and 2 h post-load glucose values, irrespective of current GDM diagnosis. The most consistent associations with a diagnosis of GDM were a positive family history and a history of GDM. Age above 30 years at oral glucose testing also showed significant association. There was no BMI threshold associated with a significant risk of GDM for those women presenting in the first trimester. CONCLUSIONS: GDM is a common metabolic condition in Nigeria. Onset before the 24th week of pregnancy is not uncommon.
