流行病学调查研究中的质量控制

为了解疾病状态和探究疾病的危险因素,流行病学研究在实际工作中使用的越来越频繁。对于一项流行病学研究,真实可靠的结论来之不易。而调查研究的结果真实与否取决于整个研究过程中各个环节的质量控制,因此消除或尽量减少各种误差对最终得到正确的结果结论是至关重要的。在大规模、多中心的流行病学调查中,研究覆盖的地区多,涉及的人员广,更应注重研究的质量控制体系建立。本文就流行病学调查中的设计、实施、分析阶段中可能出现的误差,对各个环节的质量控制进行综述。     

Concordance of the Composite International Diagnostic Interview Version 3.0 (CIDI 3.0) with standardized clinical assessments in the WHO World Mental Health surveys

The DSM-IV diagnoses generated by the fully structured lay-administered Composite International Diagnostic Interview Version 3.0 (CIDI 3.0) in the WHO World Mental Health (WMH) surveys were compared to diagnoses based on follow-up interviews with the clinician-administered non-patient edition of the Structured Clinical Interview for DSM-IV (SCID) in probability subsamples of the WMH surveys in France, Italy, Spain, and the US. CIDI cases were oversampled. The clinical reappraisal samples were weighted to adjust for this oversampling. Separate samples were assessed for lifetime and 12-month prevalence. Moderate to good individual-level CIDI-SCID concordance was found for lifetime prevalence estimates of most disorders. The area under the ROC curve (AUC, a measure of classification accuracy that is not influenced by disorder prevalence) was 0.76 for the dichotomous classification of having any of the lifetime DSM-IV anxiety, mood and substance disorders assessed in the surveys and in the range 0.62-0.93 for individual disorders, with an inter-quartile range (IQR) of 0.71-0.86. Concordance increased when CIDI symptom-level data were added to predict SCID diagnoses in logistic regression equations. AUC for individual disorders in these equations was in the range 0.74-0.99, with an IQR of 0.87-0.96. CIDI lifetime prevalence estimates were generally conservative relative to SCID estimates. CIDI-SCID concordance for 12-month prevalence estimates could be studied powerfully only for two disorder classes, any anxiety disorder (AUC = 0.88) and any mood disorder (AUC = 0.83). As with lifetime prevalence, 12-month concordance improved when CIDI symptom-level data were added to predict SCID diagnoses. CIDI 12-month prevalence estimates were unbiased relative to SCID estimates. The validity of the CIDI is likely to be under-estimated in these comparisons due to the fact that the reliability of the SCID diagnoses, which is presumably less than perfect, sets a ceiling on maximum CIDI-SCID concordance.     

Brachytherapy practice across Canada: A survey of workforce and barriers

PurposeTo determine the current use of brachytherapy, characteristics of the brachytherapy workforce, and barriers to development and maintenance of brachytherapy programs across Canada.Methods and MaterialsA survey was designed to inquire about the use of brachytherapy and was sent to all Canadian radiation oncologists.ResultsOf the 116 respondents, we identified 80 radiation oncologists from 33 of 41 responding centers who currently or in the past have practiced brachytherapy. Responses were received from 30% overall and 80% of provinces. Approximately 58% of the respondents treat in one site with brachytherapy, whereas 12% treat in three or more sites. Gynecologic (GYN) and genitourinary are the most commonly treated sites (49% of respondents). For all sites, there was a large range in the number of patients treated with brachytherapy by each radiation oncologist per year (i.e., cervix: 1–50). Approximately 49% of the respondents have discontinued practicing brachytherapy for a certain site, most commonly head and neck (28%), GYN (25%), and bronchus (24%). The most common reasons include reassignment or lack of a local program. The most common reasons why brachytherapy is not used for sites other than GYN and prostate include lack of infrastructure and insufficient training of radiation oncologists rather than insufficient patient numbers or lack of evidence for a benefit of brachytherapy.ConclusionsWithin its limitations, our study suggests a mismatch between demand and availability of brachytherapy programs across Canada. In light of finite resources, a rational approach to investment in brachytherapy is needed and this must be based on a formal audit of brachytherapy demand and use.

Patient-reported recall of smoking cessation interventions from a health professional

Objective

To determine the prevalence and characteristics of current cigarette smokers who report receiving health care provider interventions (‘5A's’: ask, advise, assess, assist, arrange) for smoking cessation.

Methods

Data came from the 2009–2010 National Adult Tobacco Survey, a telephone survey of United States adults aged ≥ 18 years. Among current cigarette smokers who reported visiting a health professional in the past year (n = 16,542), estimates were calculated overall and by sex, age, race/ethnicity, education, income, health insurance coverage, and sexual orientation.

Results

Among smokers who visited a health professional (75.2%), 87.9% were asked if they used tobacco, 65.8% were advised to quit, and 42.6% were asked if they wanted to quit. Among those wanting to quit, 78.2% were offered assistance and 17.5% had follow-up arranged. Receipt of the ‘ask’ component was lower among males and uninsured individuals. Receipt of the ‘advise’ and ‘assess’ components was lower among those aged 18–24 and uninsured individuals. Receipt of the ‘assist’ component was lower among non-Hispanic blacks. No differences were observed for the ‘arrange’ component.

Conclusions

Many current smokers report receiving health care provider interventions for smoking cessation. Continued efforts to educate, encourage, and support all health professionals to provide effective, comprehensive tobacco cessation interventions to their patients may be beneficial.     

Validity of vaccination cards and parental recall to estimate vaccination coverage: A systematic review of the literature

Immunization programs frequently rely on household vaccination cards, parental recall, or both to calculate vaccination coverage. This information is used at both the global and national level for planning and allocating performance-based funds. However, the validity of household-derived coverage sources has not yet been widely assessed or discussed. To advance knowledge on the validity of different sources of immunization coverage, we undertook a global review of literature. We assessed concordance, sensitivity, specificity, positive and negative predictive value, and coverage percentage point difference when subtracting household vaccination source from a medical provider source. Median coverage difference per paper ranged from −61 to +1 percentage points between card versus provider sources and −58 to +45 percentage points between recall versus provider source. When card and recall sources were combined, median coverage difference ranged from −40 to +56 percentage points. Overall, concordance, sensitivity, specificity, positive and negative predictive value showed poor agreement, providing evidence that household vaccination information may not be reliable, and should be interpreted with care. While only 5 papers (11%) included in this review were from low-middle income countries, low-middle income countries often rely more heavily on household vaccination information for decision making. Recommended actions include strengthening quality of child-level data and increasing investments to improve vaccination card availability and card marking. There is also an urgent need for additional validation studies of vaccine coverage in low and middle income countries.     

Correlates of seasonal flu vaccination among U.S. home health aides

Introduction

Home health aides (HAs) receive limited training and reach many older patient populations highly susceptible to influenza virus. We sought to examine socio-demographic correlates of seasonal flu vaccination receipt among HAs.

Methods

We analyzed data from the 2007 U.S. National Home Health Aide Survey, a nationally representative sample of HAs reporting on occupational status, job and demographic characteristics and receipt of seasonal flu vaccine (n = 3377).

Results

Seasonal flu vaccine receipt was low among all types of HAs (43.9%). After adjustment for socio-demographic indicators (i.e. age, gender, race and health insurance), home health, home care, hospice and personal care attendants were significantly less likely to report receiving seasonal flu vaccine as compared to licensed nursing assistants (adjusted odds ratio, AOR = 0.42, 95% CI [0.20–0.85]; 0.41, [0.17–0.99]; 0.50, [0.26–0.97], and 0.53, [0.26–0.99], respectively).

Conclusion

Targeted effective vaccination campaigns are needed to improve vaccination rates among home health aides.
