Use of Asthma APGAR Tools in Primary Care Practices: A Cluster-Randomized Controlled Trial.

PURPOSE: The purpose of this study was to assess patient and practice outcomes after introducing the Asthma APGAR (Activities, Persistent, triGGers, Asthma medications, Response to therapy) tools into primary care practices. METHODS: We used a pragmatic cluster-randomized controlled design in 18 US family medicine and pediatric practices to compare outcomes in patients with persistent asthma aged 5 to 45 years after introduction of the Asthma APGAR tools vs usual care. Patient outcomes included asthma control, quality of life, and emergency department (ED), urgent care, and inpatient hospital visits. The practice outcome was adherence to asthma guidelines. RESULTS: We enrolled 1,066 patients: 245 children, 174 adolescents, and 647 adults. Sixty-five percent (692 patients) completed both baseline and 12-month questionnaires, allowing analysis for patient-reported outcomes. Electronic health record data were available for 1,063 patients (99.7%) for practice outcomes. The proportion of patients reporting an asthma-related ED, urgent care, or hospital visit in the final 6 months of the study was lower in the APGAR practices vs usual care practices (10.6% vs 20.9%, P = .004). The percentage of patients with "in control" asthma increased more between baseline and 1 year in the APGAR group vs usual care group (13.5% vs 3.4%, P =.0001 vs P =.86) with a trend toward better control scores and asthma-related quality of life in the former at 1 year (P ≤.06 and P = .06, respectively). APGAR practices improved their adherence to 3 or more guideline elements compared with usual care practices (20.7% increase vs 1.9% decrease, P = .001). CONCLUSIONS: Introduction of the Asthma APGAR tools improves rates of asthma control; reduces asthma-related ED, urgent care, and hospital visits; and increases practices' adherence to asthma management guidelines.

Adverse impacts of chronic pain on health-related quality of life, work productivity, depression and anxiety in a community-based study.

Background: Chronic pain has major clinical and social consequences. Few studies have examined any variation in the extent of impairment on quality of life and work productivity by site and type of chronic pain. Objective: The objective of our study is to examine adverse impacts of chronic pain on physical and psychological health and work productivity. Methods: Our community-population study was based on a phone-interview of adults with chronic pain, residing in Olmsted County, MN. Chronic pain groups were categorized into abdominal pain, back pain, joint pain, multisite pain, neuropathic pain or no chronic pain. We used standardized instruments, including the Brief Pain Inventory, the Patients Health Questionnair-9, and Work Productivity and Activity Impairment Questionnaire. Results: We evaluated 591 patients suffering from chronic pain and 150 participants with no chronic pain. Almost one third of patients with multisite pain (33%) and neuropathic pain (32%) reported mild/major depressive symptoms. Patients suffering from chronic pain, particularly from multisite pain and neuropathic pain, reported significant pain interferences with daily activities and impairments in physical function. Chronic pain was significantly associated with reduced performance at work but not with missed work hours. The average reported reduction in work productivity ranged from 2.4 hours (±5.6) per week for adults with joint chronic pain to 9.8 hours (±11.1) per week for adults with multisite chronic pain. Conclusions: Chronic pain, particularly multisite pain and neuropathic pain, significantly affected physical and psychological health. Chronic pain is a multifaceted health condition that requires a multidisciplinary treatment approach.

Risk Factors for Herpes Zoster Among Adults.

Background. The causes of varicella-zoster virus reactivation and herpes zoster (HZ) are largely unknown. We assessed potential risk factors for HZ, the data for which cannot be obtained from the medical sector. Methods. We conducted a matched case-control study. We established active surveillance in Olmsted County, Minnesota to identify HZ occurring among persons age ≥50 years during 2010-2011. Cases were confirmed by medical record review. Herpes zoster-free controls were age- and sex-matched to cases. Risk factor data were obtained by telephone interview. Results. We enrolled 389 HZ case patients and 511 matched controls; the median age was 65 and 66 years, respectively. Herpes zoster was associated with family history of HZ (adjusted odds ratio [aOR] = 1.65); association was highest with first-degree or multiple relatives (aOR = 1.87 and 3.08, respectively). Herpes zoster was also associated with prior HZ episodes (aOR = 1.82), sleep disturbance (aOR = 2.52), depression (aOR = 3.81), and recent weight loss (aOR = 1.95). Stress was a risk factor for HZ (aOR = 2.80), whereas a dose-response relationship was not noted. All associations indicated were statistically significant (P < .05). Herpes zoster was not associated with trauma, smoking, tonsillectomy, diet, or reported exposure to pesticides or herbicides (P > .1). Conclusions. We identified several important risk factors for HZ; however, the key attributable causes of HZ remain unknown.

Increasing Incidence of Herpes Zoster Over a 60-year Period From a Population-based Study.

BACKGROUND: Temporal increases in the incidence of herpes zoster (HZ) have been reported but studies have examined short study periods, and the cause of the increase remains unknown. We examined the long-term trend of HZ. METHODS: A population-based cohort study was conducted in Olmsted County, Minnesota, using data from 1945-1960 and 1980-2007. Medical records review of possible cases was performed to confirm incident cases of HZ, the patient's immune status, and prescribing of antivirals for HZ. We examined the relative change in the temporal trend in the incidence rates before and after the introduction of the varicella vaccination program. RESULTS: Of the 8017 patients with HZ, 58.7% were females and 6.6% were immunocompromised. The age- and sex-adjusted incidence rate of HZ increased from 0.76 per 1000 person-years (PY) (95% confidence interval [CI], .63-.89) in 1945-1949 to 3.15 per 1000 PY (95% CI, 3.04-3.26) in 2000-2007. The rate of increase across the time period was 2.5% per year after adjusting for age and sex (adjusted incidence rate ratio, 1.025 [95% CI, 1.023-1.026]; P < .001). The incidence of HZ significantly increased among all age groups and both sexes. We found no change in the rate of increase before vs after the introduction of the varicella vaccination program. CONCLUSIONS: The incidence of HZ has increased >4-fold over the last 6 decades. This increase is unlikely to be due to the introduction of varicella vaccination, antiviral therapy, or change in the prevalence of immunocompromised individuals.

Adherence to Asthma Guidelines in Children, Tweens, and Adults in Primary Care Settings: A Practice-Based Network Assessment.

OBJECTIVE: To assess primary care adherence to 2007 US asthma guidelines. PATIENTS AND METHODS: Patients with persistent asthma aged 5 to 65 years from 22 primary care participating practices provided the data for this analysis of baseline information from the pragmatic randomized clinical trial the Asthma Tools Study. Using a combination of abstracted medical record data and patient-reported demographic information, we assessed the medical record documentation for elements of the 2007 US asthma guidelines. Elements assessed included documentation of (1) assessment of control, (2) factors that affect control (medication adherence evaluation, inhaler technique education, and evaluation for triggers), (3) self-management support (action plan), and (4) asthma medications prescribed (short-acting ß-agonists and daily maintenance therapy). The baseline data was collected from March 16, 2009, to May 1, 2014. RESULTS: In 1176 patients (285 children, 211 tweens, and 680 adults) from 16 family medicine and 6 pediatric practices across the United States, documented guideline adherence was highest for prescription of medications (88.0% for short-acting ß-agonists and 70.4% for maintenance medications) and lowest for an asthma action plan (3.1%). Documentation of control (15.0%) and factors that affect control (inhaler technique education, 7.6%; medication adherence assessment, 32.5%; and allergy evaluation, 32.5%) was not common and even less common for adults compared with children. A total of 22.2% of the enrolled patients had no asthma-related visit in the year before enrollment. Adherence to the nonmedication elements were higher in practices located in cities of more than 250,000 people and cities that used electronic medical records. Older patient age was negatively associated with guideline adherence. CONCLUSION AND RELEVANCE: Adherence to asthma guidelines is poor in primary care practices, leaving many opportunities for improvement.

Asthma as a risk factor for zoster in adults: A population-based case-control study.

BACKGROUND: We recently reported an increased risk of herpes zoster (shingles or zoster) in children with asthma, but little is known about whether the same is true for adults with asthma. OBJECTIVE: We determined whether asthma is associated with an increased risk of zoster in adults. METHODS: This study was designed as a population-based case-control study. Zoster cases during the study period were identified among adults (aged ≥50 years) who resided in Olmsted County, Minnesota. We compared the frequency of asthma between zoster cases and birthday- and sex-matched control subjects (1:2 matching) without a history of zoster. Asthma status was ascertained based on predetermined criteria. A conditional logistic regression model was used to assess the association of asthma with risk of zoster. RESULTS: A total of 371 zoster cases and their 742 matched control subjects were enrolled. Of the 371 cases, 246 (66%) were female, 348 (94%) were white, and the mean ± SD age was 66.8 ± 10.7 years. Twenty-three percent (n = 87) of zoster cases had a history of asthma compared with 15% (n = 114) of control subjects. Controlling for pertinent covariates and confounders, there was a significant association between a history of asthma and risk of zoster (adjusted odds ratio, 1.70; 95% CI, 1.20-2.42; P = .003). The population attributable risk percentage for asthma was about 10%. CONCLUSIONS: Asthma is an unrecognized risk factor for zoster in adults. Consideration should be given to immunizing adults with asthma aged more than 50 years as a target group.

Risk of Stroke and Myocardial Infarction After Herpes Zoster in Older Adults in a US Community Population.

OBJECTIVE: To assess the risk of stroke and myocardial infarction (MI) after herpes zoster in a US community population of older adults. PATIENTS AND METHODS: We performed a community cohort study (January 1, 1986, to October 1, 2011) comparing the risk of stroke and MI in 4862 adult residents of Olmsted County, Minnesota, 50 years and older with and without herpes zoster and 19,433 sex- and age-matched individuals with no history of herpes zoster. Odds ratios are presented for MI and stroke at 3, 6, 12, and 36 months after index herpes zoster plus hazard ratios for long-term risk (up to 28.6 years). RESULTS: Individuals with herpes zoster had more risk or confounding factors for MI and stroke, suggesting that they had worse health status overall. When controlling for the multiple risk factors, those with herpes zoster were at increased risk for stroke at 3 months after herpes zoster compared with those without a history of herpes zoster (odds ratio, 1.53; 95% CI, 1.10-2.33; P=.04). The association between herpes zoster and MI at 3 months was not robust across analytic methods. Herpes zoster was not associated with an increased risk of stroke or MI at any point beyond 3 months. CONCLUSIONS: Herpes zoster was associated with only a short-term increased risk of stroke, which may be preventable with the prevention of herpes zoster.

Primary Care Physicians', Nurse Practitioners' and Physician Assistants' Knowledge, Attitudes and Beliefs Regarding COPD: 2007 To 2014.

To assess current primary care physicians', nurse practitioners' (NP) and physicians assistants' (PA) knowledge, attitudes and beliefs regarding chronic obstructive pulmonary disease (COPD) and changes from a similar 2007 assessment, we surveyed attendees of 3 regional continuing medical education programs and compared the 2013/2014 responses with responses to a similar survey completed in 2007. Survey data included information on personal demographics, agreement with perceived barriers to COPD diagnosis, awareness, and use of COPD guidelines, and beliefs regarding the value of available COPD therapies. In 2013/2014, 426 primary care clinicians (278 medical doctors [MDs] and doctors of osteopathic medicine [DO] and 148 NPs/PAs) provided useable responses (overall response rate 61%). Overall these physicians were older and more experienced than the NPs/PAs but with few other differences in responses except significantly greater physician reported use of spirometry for COPD diagnosis. About half of the clinicians reported having in-office spirometers but less than two thirds reported using them for all COPD diagnoses. All respondents reported multiple barriers to COPD diagnosis but with fewer than in 2007 reporting lack of knowledge or awareness of COPD guidelines as a major barrier. The most striking difference between 2007 and 2013/2014 responses was the marked increase in beliefs by all clinicians in the ability of COPD treatments to reduce symptoms and numbers of exacerbations. These data affirm that primary care clinicians continue to report multiple barriers to COPD diagnosis including lack of easy access to spirometry and frequent failure to include spirometry in diagnostic confirmation. However, since 2007, the clinicians report a remarkable decline in therapeutic nihilism, which may enhance their interest in learning more about diagnosing and managing COPD.

Obesity, low levels of physical activity and smoking present opportunities for primary care asthma interventions: an analysis of baseline data from The Asthma Tools Study.

BACKGROUND: Asthma prevalence, severity and outcomes are associated with various patient characteristics and lifestyle choices. AIMS: To identify potentially modifiable factors associated with poor asthma outcomes among US primary care patients. METHODS: Using baseline data from the Asthma Tools Study, we calculated cross-sectional frequencies of activity levels, smoking, secondhand smoke exposure and the presence of obesity, as well as rates of out-of-control asthma and asthma exacerbations. Frequencies were stratified by sex, and into three age groups: 5-11 years, 12-18 years and 19 years and older. Logistic regression was used to identify factors associated with each of the asthma outcomes. RESULTS: In the 901 individuals enrolled in this asthma study, tobacco smoke exposure, obesity, low activity levels, poverty, inadequately controlled asthma and high asthma-related health-care utilisation were common. Across all age groups, obesity was associated with poorer asthma outcomes: either poor asthma control (odds ratio (OR)=2.3, 95% confidence interval (CI) 1.1-4.7 in 5- to 11-year-olds and OR=1.5, 95% CI 1.1-2.2 in adults) or asthma exacerbations (OR 2.9, 95% CI 1.6-5.1 in 12- to 18-year-olds and OR 1.7, 95% CI 1.1-2.5 in adults). Among adults, smoking was associated with both measures of poorer asthma outcomes; inadequate asthma control (OR=2.3, 95% CI 1.5-3.5), and asthma exacerbations (OR 1.7, 95% CI 1.1-2.6), and low physical activity were associated with poor asthma control (OR=1.5, 95% CI 1.1-2.2). CONCLUSIONS: Obesity, low levels of physical activity and smoking are common, and they are associated with poor asthma outcomes in a sample of primary care patients, suggesting important targets for intervention.

Repeated depression screening during the first postpartum year.

PURPOSE: Postpartum depression (PPD) screening at 4 to 12 weeks' postpartum can improve outcomes for women when linked to in-practice management programs. The benefit of repeated PPD screening during the first year postpartum remains unclear. METHODS: We report a substudy of a large pragmatic trial of early PPD screening and practice management, the Translating Research into Practice for Postpartum Depression (TRIPPD) study. Outcome analyses were based on demographic information and Patient Health Questionnaire (PHQ-9) screening scores from questionnaires mailed to all enrolled women at baseline (4 to 12 weeks' postpartum) and again at 6 and at 12 months' postpartum. The main outcomes of this substudy were the 6- and 12-month rates of PHQ-9 scores that were 10 or greater for women whose baseline PHQ-9 scores were less than 10. Women whose scores were 10 or greater would be considered at high risk of PPD and appropriate for further evaluation. RESULTS: At 6 months, 134 (10.9%) of the 1,235 women who did not have PHQ-9 scores greater than 10 at baseline had elevated scores appropriate for further evaluation. At 12 months, 59 (6.1%) of the 969 women who did not have PHQ-9 scores greater than 10 at baseline or at 6 months had elevated scores. Together the 6- and 12-month repeated screenings identified 193 women at high risk of depression. This finding represents 13.5% of the 1,432 women whose screening results were negative for PPD at baseline. CONCLUSIONS: Repeated PPD screening at 6 and 12 months' postpartum increases the percentage of women identified as being at high risk of PPD. Further work will be required to understand the impact of this repeated screening on patient outcomes.

Herpes zoster vaccine effectiveness and manifestations of herpes zoster and associated pain by vaccination status.

Options for managing herpes zoster (HZ)-related pain and complications have limited effectiveness, making HZ prevention through vaccination an important strategy. Limited data are available on HZ vaccine effectiveness against confirmed HZ and manifestations of HZ among vaccinated persons. We conducted a matched case-control study to assess HZ vaccine effectiveness for prevention of HZ and other HZ-related outcomes and a cohort study of persons with HZ to compare HZ-related outcomes by vaccination status. Cases were identified through active surveillance among persons age ≥ 60 years with HZ onset and health-care encounters during 2010-2011 in Southeastern Minnesota. Controls were age- and sex-matched to cases. Data were collected by medical record review and from participants via interviews and daily pain diaries. 266 HZ case-patients and 362 matched controls were enrolled in the vaccine effectiveness studies and 303 case-patients in the cohort study of HZ characteristics by vaccination status. Vaccination was associated with 54% (95% CI:32%-69%) reduction in HZ incidence, 58% (95% CI:31%-75%) reduction in HZ prodromal symptoms, and 70% (95% CI:33%-87%) reduction in medically-attended prodrome. HZ vaccine was statistically significant effective at preventing postherpetic neuralgia (PHN) measured at 30 d after rash onset, 61% (95% CI: 22%-80%). Among persons who developed HZ, no differences were found by vaccination status in severity or duration of HZ pain after rash onset. In this population-based study, HZ vaccination was associated with >50% reduction in HZ, HZ prodrome, and medically-attended prodrome.

Depressive symptoms and access to mental health care in women screened for postpartum depression who lose health insurance coverage after delivery: findings from the Translating Research into Practice for Postpartum Depression (TRIPPD) effectiveness study.

OBJECTIVE: To determine the impact of losing health insurance coverage on perceived need for and access to mental health care in women screened for postpartum depression (PPD) in primary care settings. PATIENTS AND METHODS: The study sample included 2343 women enrolled in a 12-month, multisite, randomized trial that compared clinical outcomes of a comprehensive PPD screening and management program with usual care (March 1, 2006, through August 31, 2010). Screening for PPD occurred at the first postpartum visit (5-12 weeks) using the Edinburgh Postnatal Depression Scale followed by the 9-item Patient Health Questionnaire. Insurance status during the prenatal period, at delivery, and during the first postpartum year and perceived need for and access to mental health care during the first postpartum year were assessed via questionnaires completed by individual patients and participating practices. RESULTS: Rates of uninsured increased from 3.8% during pregnancy and delivery (n=87 of 2317) to 10.8% at the first postpartum visit (n=253 of 2343) and 13.7% at any subsequent visit to the practice after 2 months post partum (n=226 of 1646) (P<.001, both comparisons vs baseline). For patients with data on insurance type during follow-up, insurance loss occurred primarily in Medicaid beneficiaries. Nine-item Patient Health Questionnaire scores and self-reported need for mental health care did not differ significantly between patients who remained insured and those who lost insurance during the first postpartum year. However, of patients who reported the need for mental health care, 61.1% of the uninsured (n=66 of 108) vs 27.1% of the insured (n=49 of 181) reported an inability to obtain mental health care (P<.001). CONCLUSION: Loss of insurance during the first postpartum year did not significantly affect depressive symptoms or perceived need for mental health care but did adversely affect self-reported ability to obtain mental health care.

Comparing the Asthma APGAR system and the Asthma Control Test™ in a multicenter primary care sample.

OBJECTIVE: To compare asthma control assessment using the Asthma APGAR system, a tool developed by primary care clinicians, in a multicenter primary care sample with the Asthma Control Test (ACT™)/Childhood Asthma Control Test (CACT™), a tool developed by asthma specialists. PATIENTS AND METHODS: This is a substudy of a multicenter, randomized, controlled pragmatic trial that tests the effectiveness of the Asthma APGAR system in primary care practices. As part of the study, enrolled patients completed both the ACT™/CACT™ and the Asthma APGAR system between March 1, 2011, and December 31, 2011. Kappa and McNemar statistics were used to compare the results of questionnaires. RESULTS: Of the 468 patients in our sample, 306 (65%) were classified as not controlled by the ACT™/CACT™ or the Asthma APGAR system. The overall agreement was 84.4%, with a kappa value of .68 (substantial agreement) and a McNemar test P value of .35 (suggesting no significant difference in the direction of disagreement). Of those with poor control as defined by the Asthma APGAR system, 23.8% (73) had no controller medications and 76.5% (234) were seldom or sometimes able to avoid identified triggers for their asthma. Of those who stated that they had been prescribed controller medications, 116 of 332 (35%) stated that they did not use the controller medication on a daily basis. CONCLUSION: The Asthma APGAR system and the ACT™/CACT™ similarly assess asthma control in a multicenter primary care-based sample. The Asthma APGAR system identified an "actionable item" in more than 75% (234) of the individuals with poor asthma control, thus linking an assessment of poor asthma control with a management strategy.

Quantifying traffic exposure.

Living near traffic adversely affects health outcomes. Traffic exposure metrics include distance to high-traffic roads, traffic volume on nearby roads, traffic within buffer distances, measured pollutant concentrations, land-use regression estimates of pollution concentrations, and others. We used Geographic Information System software to explore a new approach using traffic count data and a kernel density calculation to generate a traffic density surface with a resolution of 50 m. The density value in each cell reflects all the traffic on all the roads within the distance specified in the kernel density algorithm. The effect of a given roadway on the raster cell value depends on the amount of traffic on the road segment, its distance from the raster cell, and the form of the algorithm. We used a Gaussian algorithm in which traffic influence became insignificant beyond 300 m. This metric integrates the deleterious effects of traffic rather than focusing on one pollutant. The density surface can be used to impute exposure at any point, and it can be used to quantify integrated exposure along a global positioning system route. The traffic density calculation compares favorably with other metrics for assessing traffic exposure and can be used in a variety of applications.

Herpes zoster eye complications: rates and trends.

PURPOSE: To provide population-based data on the risk, types, and outcomes of eye involvement in herpes zoster (HZ). METHODS: A cohort study based on review of the medical records of patients in whom HZ was diagnosed between January 1, 1980, and December 31, 2007, was performed. Herpes zoster was confirmed by the presence of the typical rash and symptoms or by laboratory testing, and eye involvement was confirmed by ophthalmologists' evaluation. Information was collected on all eye diagnoses and on HZ eye-related visits, treatments, procedures, and outcomes. RESULTS: Of the 2035 individuals with HZ in any dermatome, 184 (9.0%) had eye involvement. The mean age of the 184 was 62.6 years, and 5 cases occurred in patients younger than 21. Overall, 6.5% (12) were immunosuppressed at the time of the eye complications. The rate of increase in HZ eye involvement was 23% by decade from 1980 to 2007. Common eye complications were keratitis (n=144, 76.2%), uveitis/iritis (n=88, 46.6%), and conjunctivitis (n=67, 35.4%). Recurrent keratitis and recurrent iritis/uveitis occurred in 6.9% (13) and 7.4% (14), respectively. Outcomes included 6 patients (3.3%) with new vision decrements to 20/200 or worse. Two individuals had successful corneal transplants. Another 6 individuals (3.3%) had lid ptosis that affected vision, including 1 elderly woman with permanent unilateral tarsorrhaphy. Severe HZ eye pain was reported to be directly responsible for 1 unsuccessful suicide attempt. Acute retinal necrosis did not develop in any individual. A mean of 10.8 eye visits per patient with HZ and eye involvement was reported to continue for a mean of 308 days. CONCLUSION: Eye complications are common and result in considerable health care use and permanent vision decrement in about 6.6% (6) of individuals with HZ eye involvement. Most health care use and long-term adverse outcomes occurred in patients in whom prevention of HZ with the zoster vaccine would be possible.

Protocol for the asthma tools study: a pragmatic practice-based research network trial.

BACKGROUND: Asthma is common among children, adolescents, and adults. However, management of asthma often fails to follow evidence-based guidelines. Control assessments have been developed, validated against expert opinion, and disseminated. However, in primary care, assessment of control is only one step in asthma management. To facilitate integration of the evidence-based guidelines into practice, tools should also guide the next steps in care. The Asthma APGAR tools do just that, incorporating a control assessment as well as assessment of the most common reasons for inadequate and poor control. The Asthma APGAR tool is also linked to a care algorithm based on the 2007 National Heart, Lung, and Blood Institute asthma guidelines. The objective of this study is to assess the impact of implementation of the Asthma APGAR on patient asthma outcomes in primary care practices. METHODS: A total of 1400 patients aged 5-60 years with physician-diagnosed asthma are enrolled in 20 practice-based research network (PBRN) practices randomized to intervention or usual care. The primary outcomes are changes in patient self-reported asthma control, asthma-related quality of life, and rates of exacerbations documented in medical records over the 18-24 months of enrollment. Process measures related to implementation of the Asthma APGAR system into daily care will also be assessed using review of medical records. Qualitative assessments will be used to explore barriers to and facilitators for integrating the Asthma APGAR tools into daily practice in primary care. DISCUSSION: Data from this pivotal pragmatic study are intended to demonstrate the importance of linking assessment of asthma and management tools to improve asthma-related patient outcomes. The study is an effectiveness trial done in real-world PBRN practices using patient-oriented outcome measures, making it generalizable to the largest possible group of asthma care providers and primary care clinics.

Exacerbations in the pre- and post-COPD diagnosis periods.

PURPOSE: Chronic obstructive pulmonary disease (COPD) is usually recognized in its later stages, delaying therapeutic opportunities. Screening questionnaires have modest sensitivities and specificities. Adding questions about prior respiratory events might improve screening characteristics. METHODS: Using administrative data from all health care facilities in Olmsted County, Minnesota USA, we identified all adults with an initial diagnosis of COPD from 2005 through 2007. For each individual we identified all coded lower and upper respiratory events in the 2 years before and the 2 years after the COPD diagnosis and categorized them as probable or possible COPD exacerbations. RESULTS: 356 women and 346 men (N = 702) with a mean age of 67.5 years and 66.6 years respectively had a first diagnosis of COPD during the study period. Respiratory events in the 2 years prior to a COPD diagnosis were common with a range of 0 to 16 events per individual and a mean (SD) of 2.04 (2.14), 1.38 (1.86) all of which were probable COPD exacerbations. Prediagnostic respiratory events were predictive of similar events in the post diagnostic period (odds ratio = 1.6, 95% confidence interval [CI] 1.3 to 1.8). CONCLUSION: Inquiring about the number and type of upper or lower respiratory events in the 2 past years may be a useful addition to the "screening" criteria to improve COPD identification, especially those at risk of frequent exacerbations.

Postpartum Depression: Screening, Diagnosis, and Management Programs 2000 through 2010.

The value and appropriateness of universal postpartum depression (PPD) screening remains controversial in the United States. To date, several PPD screening programs have been introduced and a few have been evaluated. Among those programs that have been evaluated, most report screening rates, diagnosis rates, or treatment initiation rates. Only four studies included patient outcomes such as the level of depressive symptoms at 6 to 12 months postpartum, and only two reported success in improving outcomes. Program characteristics that appear to result in low rates of diagnosis and followup after PPD screening include requirements for a formal psychiatric evaluation, the need to refer women to another site for therapy, and failure to integrate the PPD screening into the care provided at the woman's or her child's medical home. The two programs that reported improved outcomes were both self-contained within primary care and included specific followup, management, and therapy procedures. Both resulted in the need for outside referrals in less than 10% of women diagnosed with postpartum depression. Future studies should be based on the successful programs and their identified facilitators while avoiding identified barriers. To affect policies, the future program must report maternal outcomes going beyond the often reported process outcomes of screening, referral, and therapy initiation rates.

TRIPPD: a practice-based network effectiveness study of postpartum depression screening and management.

PURPOSE: Postpartum depression is common but inadequately recognized and undertreated. Continuing depressive symptoms are associated with adverse outcomes for the woman, her infant, and family. We wanted to determine the effect of a practice-based training program for screening, diagnosis, and management of depression in postpartum mothers. METHODS: In this practice-based effectiveness study, 28 practices were randomized to usual care (n = 14) or intervention (n = 14), and 2,343 women were enrolled between 5 and 12 weeks' postpartum. The intervention sites received education and tools for postpartum depression screening, diagnosis, initiation of therapy, and follow-up within their practices. Usual-care practices received a 30-minute presentation about postpartum depression. Screening information for the usual care was obtained from baseline surveys sent directly to the central site but was not available for patient care. Outcomes were based on patient-reported outcomes (level of depressive symptoms) from surveys at 6 and 12 months, plus medical record review (diagnosis and therapy initiation). RESULTS: Among the 2,343 women enrolled, 1,897 (80.1%) provided outcome information, and were included in the analysis. Overall, 654 (34.5% of 1,897) women had elevated screening scores indicative of depression, with comparable rates in the intervention and usual-care groups. Among the 654 women with elevated postpartum depression screening scores, those in the intervention practices were more likely to receive a diagnosis (P = .0006) and therapy for postpartum depression (P = .002). They also had lower depressive symptom levels at 6 (P = .07) and 12 months' (P=.001) postpartum. CONCLUSIONS: Primary care-based screening, diagnosis, and management improved mother's depression outcomes at 12 months. This practical approach could be implemented widely with modest resources.
