Successful Provision of Long-Acting Reversible Contraception in a Sexual Health Clinic.

BACKGROUND: Women who attend sexual health clinics are at high risk for sexually transmitted infections and unintended pregnancy. Long-acting reversible contraceptives (LARC) are very effective contraceptive methods, but the provision of LARC in such clinics is not well described in the literature. METHODS: We conducted a retrospective chart review of women who presented to Denver Sexual Health Clinic for any reason and received family planning services between April 1, 2016, and October 31, 2018. We assessed demographic and clinical factors associated with contraceptive method received and conducted a subanalysis of those with intrauterine device (IUD) insertions on the same-day versus delayed insertion. Among those who received an IUD, we assessed rates of pelvic inflammatory disease (PID) 30 days after insertion. RESULTS: Of the 5064 women who received family planning services in our clinic, 1167 (23%) were using a LARC method at the time of their visit. Of the 3897 who were not using a LARC, fewer women, 12.6%, chose LARC (IUD and progestin implant), compared with 33.3% who chose new short-acting reversible contraceptives. Further analysis of the 270 IUD initiators revealed 202 (74.8%) received the IUD on the same day, whereas 68 (25.2%) had delayed IUD insertion. There were 9 incident cases of gonorrhea or chlamydia in those who received same-day IUD and 1 incident case among those who had delayed IUD insertion. There were no cases of PID at 30 days after insertion in either group. CONCLUSIONS: Study findings support IUD provision in a sexual health clinic on the day of initial visit without increased risk of PID.

Using Spatial Analysis to Inform Community Immunization Strategies.

INTRODUCTION: Recent pertussis outbreaks in the United States suggest our response to local disease outbreaks (eg, vaccine-preventable Bordetella pertussis) may benefit from understanding and applying spatial analytical methods that use data from immunization information systems at a subcounty level. METHODS: A 2012 study on Denver, CO, residents less than 19 years of age confirmed pertussis cases and immunization information system records were geocoded and aggregated to the census tract (CT) level. An algorithm assessed whether individuals were up-to-date (UTD) for pertussis vaccines. Pearson, Spearman, and Kendall correlations assessed relations between disease incidence and pertussis vaccine coverage. Using spatial analysis software, disease incidence and UTD rates were spatially weighted, and smoothed. Global and local autocorrelations based on univariate Moran's I spatial autocorrelation statistics evaluated whether a CT's rate belong to a cluster based on incidence or UTD measures. RESULTS: Overall disease incidence rate was 116.8/100 000. Assessment of pertussis vaccination coverage was available for 90% of the population. Among 134 672 Denver residents less than 19 years old, 103 496 (77%) were UTD for pertussis vaccines. Raw correlation coefficients showed weak relationships between incidence and immunization rates due to the presence of outliers. With geospatial and clustering analysis, estimates and correlation coefficients were improved with statistically significant Moran's I values for global and local autocorrelations rejecting the null hypothesis that incidence or UTD rates were randomly distributed. With evidence indicating the presence of clusters, smoothed and weighted disease incidence and UTD rates in 144 CTs identified 21 CTs (15%) for potential public health intervention. CONCLUSIONS: Correlation of raw disease incidence and vaccine UTD rates in subcounty regions showed limited association, providing limited information for decision making. By assessing for clusters using spatial analysis methods, we identified CTs with higher incidence and lower immunization coverage for targeted public health interventions.

Integration of family planning services into a sexually transmitted disease clinic setting.

BACKGROUND: Sexually transmitted diseases (STDs) and unintended pregnancy are significant and costly public health concerns. Integrating family planning services (FPS) into STD visits provides an opportunity to address both concerns simultaneously. Our objectives were to create an electronic eligibility reminder to identify male and female patients eligible for FPS during an STD clinic visit and measure FPS use, additional cost of integrated services, and patient/provider satisfaction and to explore the impact on incident pregnancy and STDs. METHODS: Quasi-experimental design compared enrollment and patient/provider satisfaction before (2008) and after implementation (2010). Incident pregnancy and STD 12 months after the initial visit before and after were explored. Time and cost were calculated. Quantitative and qualitative analyses were performed. RESULTS: A total of 9695 clients (male, 5842; female, 3853) in 2008 and 10,021 clients (male, 5852; female, 4169) in 2010 were eligible for FPS. Enrollment in FPS increased (2008: 51.6%, 2010: 95.3%; P < 0.01). Total additional cost was US$29.25/visit, and additional staff time was 4.01 minutes for integrated visits. Staff satisfaction increased and client satisfaction remained high. Among women returning within 12 months (39.6% in 2008, 37.1% in 2010), pregnancies were lower among enrolled versus nonenrolled women for 2008 (7.7% vs. 19.5%, P < 0.01) and 2010 (13.1% vs. 25.9%, P = 0.05). Incident STDs did not differ. DISCUSSION: An electronic eligibility reminder of FPS increased FPS use. Integration of FPS with STD services is feasible, is well accepted, and increases costs minimally. Integration may reduce pregnancy rates without increasing STD rates.

Acculturation and outcomes among patients with heart failure.

BACKGROUND: Acculturation to US society among minority patients may-beyond race and ethnicity alone-influence health outcomes beyond race and ethnicity alone. In particular, those who are foreign-born and who do not speak English as their primary language may have greater challenges interacting with the health care system and thus be at greater risk for adverse outcomes. METHODS AND RESULTS: We studied patients hospitalized with a principal discharge diagnosis of heart failure between January 2000 and December 2007 in an integrated delivery system that cares for minority patients. Individuals were defined as having low acculturation if their primary language was not English and their country of birth was outside of the United States. Multivariable logistic regression and Cox proportional hazards regression were used to determine the independent risk of 30-day rehospitalization and 1-year mortality, respectively. Candidate adjustment variables included demographics (age, sex, race/ethnicity), coexisting illnesses, laboratory values, left ventricular systolic function, and characteristics of the index admission. Of 1268 patients, 30% (n=379) were black, 39% (n=498) were Hispanic, and 27% (n=348) were white. Eighteen percent (n=228) had low acculturation. After adjustment, low acculturation was associated with a higher risk of readmission at 30 days (odds ratio, 1.70; 95% confidence interval, 1.07-2.68) but not 1-year all-cause mortality (hazard ratio, 0.69; 95% confidence interval, 0.42-1.14). CONCLUSIONS: Patients with heart failure who are foreign-born and do not speak English as their primary language have a greater risk of rehospitalization, independent of clinical factors and race/ethnicity. Future studies should evaluate whether culturally concordant interventions focusing on such patients may improve outcomes for this patient population.

Reducing cardiovascular disease risk using patient navigators, Denver, Colorado, 2007-2009.

INTRODUCTION: Early identification of cardiovascular disease (CVD) risk is important to reach people in need of treatment. At-risk patients benefit from behavioral counseling in addition to medical therapy. The objective of this study was to determine whether enhanced counseling, using patient navigators trained to counsel patients on CVD risk-reduction strategies and facilitate patient access to community-based lifestyle-change services, reduced CVD risk among at-risk patients in a low-income population. METHODS: We compared clinical characteristics at baseline and 12-month follow-up among 340 intervention and 340 comparison patients from community health centers in Denver, Colorado, between March 2007 and June 2009; all patients had a Framingham risk score (FRS) greater or equal to 10% at baseline. The intervention consisted of patient-centered counseling by bilingual patient navigators. At baseline and at 6-month and 12-month follow-up, we assessed health behaviors of intervention participants. We used an intent-to-treat approach for all analyses and measured significant differences by χ(2) and t tests. RESULTS: We found significant differences in several clinical outcomes. At follow-up, the mean FRS was lower for the intervention group (mean FRS, 15%) than for the comparison group (mean FRS, 16%); total cholesterol was lower for the intervention group (mean total cholesterol, 183 mg/dL) than for the comparison group (mean total cholesterol, 197 mg/dL). Intervention participants reported significant improvements in some health behaviors at 12-month follow-up, especially nutrition-related behaviors. Behaviors related to tobacco use and cessation attempts did not improve. CONCLUSION: Patient navigators may provide some benefit in reducing risk of CVD in a similar population.

Association between provision of initial family planning services and unintended pregnancy among women attending an STD clinic.

BACKGROUND: Most sexually transmitted disease (STD) clinics focus solely on STD treatment and prevention. However, women seeking care are also at high risk for unintended pregnancy. We sought to examine the relationship between baseline demographic and clinical characteristics and incident pregnancy among women provided initial contraceptive services in an STD clinic. METHODS: Computerized record review of women attending an STD clinic who initiated contraception, were seen at least twice within a 4-year period (repeat attendees), and indicated no intention of pregnancy were included in these analyses. Associations between baseline demographic, behavioral, and clinical characteristics and incident pregnancy were assessed using multivariate logistic regression. RESULTS: Among 4617 women seen from 2003 to 2006, 710 (15%) were repeat attendees and 3907 (85%) were single attendees (seen only during a single year). Among the repeat attendees, 642 (90%) indicated no interest in pregnancy, of whom 124 (19%) had a subsequent pregnancy. Using multivariate analysis and controlling for age and race/ethnicity, incident pregnancy was associated with previous pregnancy (OR 2.57, 95% CI 1.63-4.04),

The association of adherence to antiretroviral therapy with healthcare utilization and costs for medical care.

BACKGROUND: The association between antiretroviral adherence, healthcare utilization and medical costs has not been well studied. OBJECTIVE: To examine the relationship of adherence to antiretroviral medications to healthcare utilization and healthcare costs. METHODS: A retrospective cohort study was conducted using data from 325 previously antiretroviral medication-naive HIV-infected individuals initiating first antiretroviral therapy from 1997 through 2003. The setting was an inner-city safety net hospital and HIV clinic in the US. Adherence was assessed using pharmacy refill data. The average wholesale price was used for prescription costs. Healthcare utilization data and medical costs were obtained from the hospital billing database, and differences according to quartile of adherence were compared using analysis of variance (ANOVA). Multivariate logistic regression was used to assess predictors of higher annual medical costs. Sensitivity analyses were used to examine alternative antiretroviral pricing schemes. The perspective was that of the healthcare provider, and costs were in year 2005 values. RESULTS: In 325 patients followed for a mean (+/- SD) 3.2 (1.9) years, better adherence was associated with lower healthcare utilization but higher total medical costs. Annual non-antiretroviral medical costs were $US 7,612 in the highest adherence quartile versus $US 10,190 in the lowest adherence quartile. However, antiretroviral costs were significantly higher in the highest adherence quartile ($US 17,513 vs $US 8,690), and therefore the total annual medical costs were also significantly higher in the highest versus lowest adherence quartile ($US 25,125 vs $US 18,880). In multivariate analysis, for every 10% increase in adherence, the odds of having annual medical costs in the highest versus lowest quartile increased by 87% (odds ratio 1.87; 95% CI 1.45, 2.40). In sensitivity analyses, very low antiretroviral prices (as seen in resource-limited settings) inverted this relationship - excellent adherence was cost saving. CONCLUSION: Better adherence to antiretroviral medication was associated with decreased healthcare utilization and associated costs; however, because of the high cost of antiretroviral therapy, total medical costs were increased. Combination antiretroviral therapy is known to be cost effective; lower antiretroviral costs may make it cost saving as well.

Durability of adherence to antiretroviral therapy on initial and subsequent regimens.

There is uncertainty regarding the durability of adherence to antiretroviral therapy. This study is a retrospective review of previously antiretroviral naïve patients initiating therapy between 1997 and 2002. Antiretroviral adherence was calculated using prescription refill data and was analyzed over time on an initial regimen and on sequential antiretroviral regimens. Three hundred forty-four patients were included. The median lengths of the first, second, and third regimens were stable at 1.7 years, 1.2 years, and 1.5 years, respectively (p = 0.10). In multivariate analysis the factor most significantly associated with earlier initial regimen termination was poor adherence. On an initial regimen, adherence decreased over time and declined most rapidly in patients with the shortest regimens (4 to <16 months, -43% per year), followed by patients with intermediate regimen duration (16 to <28 months, -19% per year), and then patients with longer regimens (>/=28 months, -5% per year). In patients progressing to a third regimen, there was a trend toward decreasing adherence over successive regimens. In conclusion, sequential antiretroviral regimens are of similar lengths, with adherence being highly associated with first regimen duration. Adherence decreases during an initial regimen and on sequential antiretroviral regimens. Effective and durable interventions to prevent declining adherence are needed.

Selective drug taking during combination antiretroviral therapy in an unselected clinic population.

OBJECTIVES: Multidrug therapy is necessary to achieve sustained viral suppression. Discordant adherence to individual components of a multidrug regimen may lead to adverse outcomes. METHODS: Antiretroviral-naive patients initiating therapy from 1997 through 2002 were included. Adherence for each antiretroviral was determined using pharmacy refill data. Selective drug taking was defined as > or =5% difference in adherence between 2 components of an antiretroviral regimen lasting at least 60 days. RESULTS: A total of 322 of 415 patients (78%) met inclusion criteria. Selective drug taking occurred in 47 of 322 patients (15%) and on 51 of 438 regimens (12%). Factors associated with selective drug taking were lower baseline CD4 lymphocyte count (adjusted odds ratio [AOR]: 1.3, 95% CI: 1.1 to 1.6 per 100 cell/microL decrease); 3 times daily dosing schedule (AOR: 4.1, 95% CI: 1.1 to 15.5); and the presence of significant adverse drug events (AOR: 2.9, 95% CI: 1.3 to 6.4). Regimens containing a fixed-dose combination dosage form were less likely to have selective drug taking (AOR: 0.5, 95% CI: 0.2 to 0.99). Outcomes independently associated with selective drug taking included earlier progression to a new AIDS-defining illness or death (hazard ratio: 2.3, 95% CI: 1.2 to 4.5). CONCLUSIONS: Selective drug taking was relatively common among patients taking combination antiretroviral therapy. The factor most closely associated with selective drug taking was the presence of an adverse drug event. Clinical outcomes appeared worse in patients with selective drug taking.

Antidepressant treatment improves adherence to antiretroviral therapy among depressed HIV-infected patients.

BACKGROUND: Antiretroviral regimens for HIV-infected patients require strict adherence. Untreated depression has been associated with medication nonadherence. We proposed to evaluate the effect of antidepressant treatment (ADT) on antiretroviral adherence. METHODS: Data were retrieved for HIV-infected patients seen at an urban health care setting (1997-2001) from chart review and administrative and pharmacy files. Antiretroviral adherence was determined for depressed patients stratified by receipt of and adherence to ADT. Antiretroviral adherence was compared before and after initiation of ADT. RESULTS: Of 1713 HIV-infected patients, 57% were depressed; of those, 46% and 52% received ADT and antiretroviral treatment, respectively. Antiretroviral adherence was lower among depressed patients not on ADT (vs. those on ADT; P = 0.012). Adherence to antiretroviral treatment was higher among patients adherent to ADT (vs. those nonadherent to antidepressant treatment; P = 0.0014). Antiretroviral adherence improved over a 6-month period for adherent, nonadherent, and nonprescribed ADT groups; however, the mean pre- versus post-6-month change in antiretroviral adherence was significantly greater for those prescribed antidepressants. CONCLUSIONS: Depression was common, and antiretroviral adherence was higher for depressed patients prescribed and adherent to ADT compared with those neither prescribed nor adherent to ADT. Attention to diagnosis and treatment of depressive disorders in this population may improve antiretroviral adherence and ultimate survival.

Initiating contraception in sexually transmitted disease clinic setting: a randomized trial.

OBJECTIVE: Our purpose was to determine the effectiveness of sexually transmitted disease (STD) clinic-initiated contraceptive care. STUDY DESIGN: Nonpregnant women (n=877) attending an urban STD clinic using either no contraception or only condoms were randomly assigned to either an intervention (n=437) or control group (n=440). Both groups received condoms with spermicide and a referral list of primary care providers (PCP) for ongoing reproductive health care, and the intervention group also received enhanced contraceptive counseling, initial provision of contraception, and facilitated referral to a PCP. Outcomes measured at 4-, 8-, and 12-month follow-up were transition to a PCP, effective contraceptive use (ECU), interval pregnancy, and STD. RESULTS: The median time to PCP transition was 79 days for the intervention group versus 115 days for the control group (P=.007). Rates of ECU were higher for the intervention group than for control group at the 4-month visit (50% vs 22%, P<.0001) as well as the 8-month visit, although in the intervention group ECU diminished over the course of the study. During follow-up, pregnancy outcomes were documented for 229 women (26.1%), for an overall pregnancy rate of 38.2 per 100 person-years of follow-up. Of the 159 pregnancies defined by patient self-report, 153 (96.2%) were described as unintended and 32 (20%) resulted in a therapeutic abortion. The pregnancy rate was 15% lower in the intervention (105/437, 24.0%) than the control group (124/440, 28.2%) (P=.16), but this difference was not statistically significant. CONCLUSION: The intervention helped women transition to a PCP and initiate ECU but did not significantly reduce the pregnancy rate. More intensive interventions are needed to prevent unintended pregnancy in this high-risk population.

Predicting pregnancy risk in women attending an STD clinic.

BACKGROUND: Although sexually transmitted disease (STD) clinics focus mainly on STD treatment and prevention, women attending these clinics are also at high risk for pregnancy. GOAL: To evaluate the relationship between certain demographic and behavioral characteristics and the probability of pregnancy in women attending an urban STD clinic. STUDY DESIGN: Non-contraceptive-using women in an STD clinic-initiated randomized controlled contraception study (n = 877) were interviewed at baseline, and incident pregnancies within 1 year of enrollment were measured. Association between baseline demographic and behavioral characteristics with incident pregnancy was assessed by chi-square analysis, and logistic regression was used to assess factors associated with an incident pregnancy. RESULTS: Among the 673 women (76.7%) for whom follow-up pregnancy information was available, 220 (32.7%) incident pregnancies occurred within 1 year. By logistic regression controlling for study assignment, incident pregnancy was associated with age < or =19 years (odds ratio [OR], 2.8; 95% CI: 1.5-5.2), previous abortion (OR, 3.1; 95% CI: 1.7-5.4), frequency of sexual encounters of at least once a week (OR, 1.8; 95% CI: 1.2-2.6), and having a chlamydial infection at the time of enrollment (OR, 1.8; 95% CI: 1.0-3.2). With a combination of demographic and behavioral characteristics correlated by univariate analysis with incident pregnancy (i.e., age < or =19 years, nonwhite race, high school/general equivalency diploma or less education, previous pregnancy, no use of birth control with last intercourse, sex at least once a week, previous abortion, > or =3 partners within the past month, and <17 years of age at first pregnancy), the cumulative risk of pregnancy with 6 or more of the 9 characteristics was 51%, compared with 25.6% for women with < or =5 characteristics. CONCLUSION: For this STD clinic population, a combination of demographic and behavioral characteristics was useful when combined for identifying a subgroup of women at higher risk for subsequent pregnancy. Targeted intervention by STD care providers should include the provision for both pregnancy and STD prevention counseling.
