Depression is a common complication of pregnancy and the postpartum period. Up to 70% percent of women report depressive symptoms during their pregnancy, and approximately 10-16% meet full criteria for major depressive disorder. Women with a history of perinatal or non-perinatal major depression are likely to relapse during pregnancy. Research shows that exposure to untreated depression and stress can have negative consequences on the birth outcome and child development. Given the harmful effects of this disease on both the mother and child, it is essential that all pregnant patients be screened for depression. Literature review did not reflect many studies that focus on depression screening in this population, let alone in pregnant patients with Human Immunodeficiency Virus (HIV). Our study focuses on the impact the mandatory screening tool had on the incidence of depression screening in pregnant HIV patients.

Using standardized Quality Improvement tools Implementation of screening tool in notes & enforcing a hard stop in the medical records

We noted both qualitative & quantitative improvement in depression screening. Qualitatively the screening has been standardized by creating a universal workflow by the inclusion of screening tools (PHQ2 and PHQ9) in Electronic Medical records. Quantitatively there has been a 34.9% improvement in screening by the case managers in the post interventional quarter.

Significant improvement noted in the incidence of depression screening by implementation a mandatory screening tool

HIV-positive individuals are at significantly increased risk of depression. In low- and middle-income countries, depression is frequently under-detected, hampered by a lack of data regarding available screening tools. The 5-item World Health Organization Well-Being Index (WHO-5) is widely used to screen for depression, yet its validity in African adults with HIV has yet to be examined.

In this cross-sectional study, we enrolled HIV-positive adults presenting to an outpatient HIV clinic in Mwanza, Tanzania. Patients were administered the Patient Health Questionnaires (PHQ)-2/9 and WHO-5 questionnaires. The rate of positive screens was calculated. Fisher's exact test and Pearson's correlation coefficients between PHQ-2/9 and WHO-5 scores were calculated.

We enrolled 72 HIV-positive adults: rates of positive depression screen were 62.5%, 77.8%, and 47.2% according to PHQ-2, PHQ-9, and WHO-5, respectively. PHQ and WHO results for depression were significantly associated (Fisher's exact test: PHQ-2 v. WHO-5, p = 0.028; PHQ-9 v. WHO-5, p = 0.002). The level of correlation between PHQ and WHO results for depression was moderate (Pearson's correlation coefficient: PHQ-2 v. WHO-5 −0.3289; PHQ-9 v. WHO-5 −0.4463).Per Mantel–Haenszel analysis, screening results were significantly more concordant among patients in the following strata: men, age >40, Sukuma ethnicity, Christian, unmarried, self-employed, at least primary school education completed, and higher than the median income level.

WHO-5 scores correlated well with those of the PHQ-9, suggesting that the WHO-5 represents a valid screening tool. The concordance of PHQ-9 and WHO-5 results was poorer in marginalized socioeconomic groups. Positive depression screens were exceedingly common among HIV-positive Tanzanian adults according to all three questionnaires.

It has been suggested that screening interventions may be effective for suicide prevention. Few studies, however, have reported their effects on outcome measures, including death by suicide among middle-aged adults.

We used a quasi-experimental parallel cluster design with matched community-based intervention and control municipalities (total eligible population: 90 000) in Japan. At-risk residents within the intervention area were invited for universal depression screening and subsequent care/support. We compared changes in suicide incidence of adults aged 40–64 years for the 4-year pre- and post-implementation periods in the intervention group with the control group and the whole country. Incidence rate ratios (IRRs) of the outcomes were adjusted for age group, gender and interaction terms, using mixed-effects negative binomial regression models. Suicide rates among intervention and control subgroups were compared.

The screening procedure was offered to 52% of the intervention group, and 61% of those contacted responded over the implementation period. Suicide rates decreased more in the intervention group [IRR 0.57, 95% (CI) 0.41–0.78; F1,36 = 12.52, p = 0.001] than the control group (IRR proportion 1.63, 95% CI 1.06–2.48; F1,82 = 5.20, p = 0.025) or the whole country (IRR proportion 1.64, 95% CI 1.16–2.34; F1,42 = 8.21, p = 0.006). Sensitivity analyses confirmed the results from the primary analysis. There were lower suicide rates among both respondents and non-respondents to the screening than in the control group during the implementation period.

Prevention efforts involved in the depression screening intervention were probably successful in reducing suicide rates.

To investigate the implementation and initial impact of the Physician Integrated Network (PIN) mental health indicators, which are specific to screening and managing follow-up for depression, in three primary care practices with Shared Mental Health Care in Manitoba.

Manitoba Health undertook a primary care renewal initiative in 2006 called the PIN, which included the development of mental health indicators specific to screening and managing follow-up for depression. These indicators were implemented in three PIN group practice sites in Manitoba, which are also part of Shared Mental Health Care.

The design was a non-experimental longitudinal design. A formative evaluation investigated the implementation and initial impact of the mental health indicators using mixed methods (document review, survey, and interview). Quantitative data was explored using descriptive and comparative statistics and a content and theme analysis of the qualitative interviews was conducted. Survey responses were received from 32 out of 36 physicians from the three sites. Interviews were conducted with 15 providers.

This evaluation illustrated providers’ perceived attitudes, knowledge, skills, and behaviours related to recognizing and treating depression and expanded our understanding of primary care processes related to managing depression related to the implementation of a new initiative. Depression is viewed as an important problem in primary care practice that is time consuming to diagnose, manage and treat and requires further investigation. Implementation of the PIN mental health indicators was variable across sites and providers. There was an increase in use of the indicators across time and a general sentiment that benefits of screening outweigh the costs; however, the benefit of screening for depression remains unclear. Consistent with current guidelines, a question the findings of this evaluation suggests is whether there are more effective ways of having an impact on depression within primary care than screening.

The prevalence of depression in rural Ugandan communities is high and yet detection and treatment of depression in the primary care setting is suboptimal. Short valid depression screening measures may improve detection of depression. We describe the validation of the Luganda translated nine- and two-item Patient Health Questionnaires (PHQ-9 and PHQ-2) as screening tools for depression in two rural primary care facilities in Eastern Uganda.

A total of 1407 adult respondents were screened consecutively using the nine-item Luganda PHQ. Of these 212 were randomly selected to respond to the Mini International Neuropsychiatric Interview diagnostic questionnaire. Descriptive statistics for respondents’ demographic characteristics and PHQ scores were generated. The sensitivity, specificity and positive predictive values (PPVs), and area under the ROC curve were determined for both the PHQ-9 and PHQ-2.

The optimum trade-off between sensitivity and PPV was at a cut-off of ≧5. The weighted area under the receiver Operating Characteristic curve was 0.74 (95% CI 0.60–0.89) and 0.68 (95% CI 0.54–0.82) for PHQ-9 and PHQ-2, respectively.

The Luganda translation of the PHQ-9 was found to be modestly useful in detecting depression. The PHQ-9 performed only slightly better than the PHQ-2 in this rural Ugandan Primary care setting. Future research could improve on diagnostic accuracy by considering the idioms of distress among Luganda speakers, and revising the PHQ-9 accordingly. The usefulness of the PHQ-2 in this rural population should be viewed with caution.

Depression is a frequent problem in cancer patients, which is known to reduce quality of life; however, many cancer patients with depression are not treated because of the difficulties in assessing depression in this population. Our aim was to evaluate and improve the depression assessment strategies of palliative care (PC) physicians and oncologists.

We invited all medical oncologists and PC physicians from three cancer centers to participate in this multicenter prospective study. They were asked to classify 22 symptoms (related and specific to depression in cancer patients, related but not specific, and unrelated) as “very important,” “important,” “less important,” or “not important” for the diagnosis of depression in cancer patients, at three different time points (at baseline, after a video education program, and after 4 weeks). They were also asked to complete a questionnaire exploring physicians' perceptions of depression and of their role in its systematic screening.

All 34 eligible physicians participated. Baseline performance was good, with >70% of participants correctly classifying at least seven of nine related and specific symptoms. We found no significant improvement in scores in the immediate and 4-week follow-up tests. Additionally, 24 (83%) and 23 (79%) participants expressed support for systematic depression screening and a role for oncologists in screening, respectively.

Oncologists had good baseline knowledge about depression's main symptoms in cancer patients and a positive attitude toward being involved in screening. Underdiagnosis of depression is probably related to problems associated with the oncology working environment rather than the physicians' knowledge.
