What predicts adherence to follow-up recommendations for abnormal Pap tests among older women?

High Rate of Loss to Follow-Up Among Patients Undergoing Treatment for Premalignant Cervical Lesions at Mbarara Regional Referral Hospital, Southwestern Uganda: A Retrospective Cohort Study

BACKGROUND

For a cervical cancer control program to be effective in reducing the incidence of the disease, there should be high compliance to treatment and follow-up of women diagnosed with precursor lesions. Screening programs in low-resource countries such as Uganda are challenged by poor adherence to follow-up following treatment for premalignant cervical lesions. This study sought to describe the burden and factors associated with loss to follow-up among women undergoing treatment for premalignant cervical lesions at a tertiary hospital in southwestern Uganda.

METHODS

This was a retrospective cohort study. We reviewed the registers at the Mbarara Regional Referral Hospital (MRRH) cervical cancer clinic for a period of four years from January 2017 to December 2020. Data on age, district of residence, diagnosis, date of diagnosis, date and type of initial treatment, and date of follow-up visit were collected. We also captured data on whether patients returned on the scheduled follow-up date or within three months after the scheduled follow-up date. We defined loss to follow-up as failure to return for follow-up either on the scheduled date or within three months after the scheduled date.

RESULTS

Out of the 298 patients who underwent treatment for premalignant cervical lesions in the study period, 227 (76.2%) did not return for follow-up at one year. At bivariate analysis, failure to attend the review visit at six weeks predicted the loss to follow-up at one year following treatment for premalignant lesions almost perfectly (risk ratio (RR)=2.84, 95% confidence interval (CI): 2.18-3.71, p<0.001). Negative HIV serostatus and receiving thermocoagulation slightly increased the risk of getting lost to follow-up, while being more than 45 years old reduced the odds. At multivariate analysis, treatment with thermocoagulation (adjusted risk ratio (aRR)=1.21, 95% CI: 1.07-1.36, p=0.03) was associated with loss to follow-up at one year.

CONCLUSION

The proportion of women who did not return for follow-up at one year following treatment for premalignant cervical lesions at Mbarara Regional Referral Hospital is very high. There is a need to implement strategies such as telephone-aided reminders to prompt patients to return for follow-up following treatment for premalignant cervical lesions.

Factors associated with adherence to post-treatment follow-up among a cohort of women with acetic acid/Lugol's iodine positive lesions of the cervix in Cameroon: A retrospective cohort study

Background

Women treated for cervical precancerous lesions have up to a 30 % increased risk of developing cervical cancer compared to women in the general population. The aim of this study was to identify predictors for adherence to follow-up among women treated for precancerous lesions of the cervix in Cameroon.

Materials and Methods

The study design was a retrospective cohort analysis of a five-year follow-up for women in Cameroon who were initially treated for cervical precancer lesions in 2013. Logistic regression models were used to determine factors associated with adherence to post-treatment follow-up. Statistical significance was set at p < 0.05.

Results

Of the 344 women treated in 2013, 154 (44.77 %) never returned for a single post-treatment follow-up in five years. Marital status was the only variable statistically significantly associated with 5-year post-treatment follow-up adherence. women who had ever been married were 0.36 times (0.14 0.93)); p = 0. 0.035] less likely to adhere to post-treatment follow-up compared to women who have never been married. Although age was not statistically significant, women in the age group 30-49 years had some significance and they were 60 % [aOR, 95 %CI: 0.40 (0.18 0.89); p = 0.024] less likely to adhere to post-treatment follow-up when compared to women who were<30 years.

Conclusion

Only about half of the women treated for cervical precancer in this cohort returned for post-treatment follow-up. Conducting needs assessments among these populations that are less likely to adhere to follow-up will allow us to implement and test strategies to improve adherence to follow-up.

Barriers and facilitators of follow-up among women with precancerous lesions of the cervix in Cameroon: a qualitative pilot study

Purpose

This pilot study explores the barriers to adherence to follow-up among women with cervical precancer in urban Cameroon. While follow-up of women with a positive screening of cervical precancer is the most important aspect of cervical cancer secondary prevention, women with cervical precancer do not adhere frequently to recommended follow-up schedule in Cameroon. The aim of the study was to explore and describe the barriers and facilitators to follow-up for cervical precancer among women infected and uninfected with HIV in Cameroon.

Participants and methods

A qualitative research design was used to answer the research questions. Participants included eight HIV-infected and -uninfected women diagnosed with cervical precancer and 19 nurses. Data were collected by in-depth individual patient interviews and focus groups with nurses. An interview guide with open-ended questions, using the social ecological model as a framework, included questions that addressed the complexities of the lives of individuals and professionals within a relational context. The interviews were audio-taped and transcribed verbatim in English language. Thematic analysis of data was completed with no epistemological or theoretical perspective underpinning the analyses.

Results

Four major themes emerged from the study. They were clinic, personal, and social barriers, and strategies to improve follow-up.

Conclusion

The use of reminder phone calls and fee reduction, coupled with peer counseling and navigation of women who have been diagnosed with cervical precancer, could be effective ways of improving adherence to follow-up. Further research is needed to explore the same phenomenon among women in rural areas, especially those who were initially attended to in mobile clinics.

Pap Testing in a High-Income Country with Suboptimal Compliance Levels: A Survey on Acceptance Factors among Sicilian Women

Cervical cancer screening is uncommon, especially in low-income countries and among lower socioeconomic status people in high-income countries. The aims of this study were to examine the adherence of Sicilian women to Pap testing and to identify the determinants of this in a population with a secondary prevention attitude lower than high-income countries and the national average. A cross-sectional study called “Save Eva in Sicily” was conducted among all women aged 25–64 years, with a sample drawn by the list of general practitioners (GPs), using a proportional sampling scheme, stratified by age and resident population. The study outcome was performing a Pap test within the past three years. The association between the outcome and Pap test determinants was analyzed through a multivariable logistic regression. Among the 365 interviewed women, 66% (n = 243) had a Pap test during the last 3 years. On the other hand, 18% of the other women (n = 66) had performed at least one Pap test previously and 16% (n = 56) had never had a Pap test. In a multivariable model, GPs’ advice (adjusted OR 2.55; 95% CI 1.57–4.14) and perceived susceptibility (adjusted OR 3.24; 95% CI 1.92–5.48) increased the likelihood of the execution of a Pap test. The “Save Eva in Sicily” study identified GP advice and perceived cancer severity as the main correlates of Pap testing among Sicilian women, producing evidence regarding how policy makers can increase compliance. Interventions to increase Pap test adhesion should focus on stimulating GPs to identify patients who regularly do not undergo it and to recommend testing on a regular basis to their patients.

Cervical cytopathological changes among women with vaginal discharge attending teaching hospital

Aims:

To find cytology changes among women attending obstetrics and gynaecology clinic with complaints of vaginal discharges.

Settings and Design:

This descriptive hospital-based cytological study was conducted at the outpatient clinic of the obstetrics and gynaecology department.

Materials and Methods:

Two hundred women with complaints of vaginal discharge were selected. Their detailed histories were documented on a special request form. Pap smears were then obtained and sent for cytological examination to the cytopathology department. All low-grade squamous intraepithelial lesion (LSIL) cases were advised to follow-up with Pap smears in the next 6–12 months. Those with high-grade squamous intraepithelial lesion (HSIL) were further investigated by a cervical biopsy and managed accordingly.

Statistical Analysis Used:

The statistical analysis was performed using, the Statistical Package for Social Science (SPSS). Chi-square and cross-tabulation were used in this study.

Results:

The cytological examination of Pap smears showed no changes (i.e. negative findings) in 88 (44%) cases, while Candida species infection was the most prevalent, which was found in 67 (33.5%) of the cases. Bacterial vaginosis was found in 39 women (19.5%); 6 women (3%) were reported with dyskaryotic changes. Two cases were found to have LSIL and 4 women had HSIL.

Conclusion:

Infection is common among the illiterate group of women. Women with vaginal discharges should undergo screening tests for evaluation by cervical smear for the early detection of cervical precancer conditions. There is an urgent need to establish a screening program for cervical cancer in Sudan.

Invasive cervical cancer risk among HIV-infected women: a North American multicohort collaboration prospective study

OBJECTIVE

HIV infection and low CD4+ T-cell count are associated with an increased risk of persistent oncogenic human papillomavirus infection-the major risk factor for cervical cancer. Few reported prospective cohort studies have characterized the incidence of invasive cervical cancer (ICC) in HIV-infected women.

METHODS

Data were obtained from HIV-infected and -uninfected female participants in the North American AIDS Cohort Collaboration on Research and Design with no history of ICC at enrollment. Participants were followed from study entry or January 1996 through ICC, loss to follow-up, or December 2010. The relationship of HIV infection and CD4+ T-cell count with risk of ICC was assessed using age-adjusted Poisson regression models and standardized incidence ratios. All cases were confirmed by cancer registry records and/or pathology reports. Cervical cytology screening history was assessed through medical record abstraction.

RESULTS

A total of 13,690 HIV-infected and 12,021 HIV-uninfected women contributed 66,249 and 70,815 person-years of observation, respectively. Incident ICC was diagnosed in 17 HIV-infected and 4 HIV-uninfected women (incidence rate of 26 and 6 per 100,000 person-years, respectively). HIV-infected women with baseline CD4+ T-cells of ≥350, 200-349, and <200 cells per microliter had a 2.3, 3.0, and 7.7 times increase in ICC incidence, respectively, compared with HIV-uninfected women (P(trend) = 0.001). Of the 17 HIV-infected women, medical records for the 5 years before diagnosis showed that 6 had no documented screening, 5 had screening with low-grade or normal results, and 6 had high-grade results.

CONCLUSIONS

This study found elevated incidence of ICC in HIV-infected compared with -uninfected women, and these rates increased with immunosuppression.

Clinicopathological importance of Papanicolaou smears for the diagnosis of premalignant and malignant lesions of the cervix

Background:

Premalignant and malignant lesions are not uncommon in Pakistani women, especially in the older age-groups

Aim:

This study was conducted to determine the clinicopathological importance of conventional Papanicolaou (Pap) smears for the diagnosis of premalignant and malignant lesions of the cervix.

Materials and Methods:

Pap smears of 1000 women were examined from January 2007 to June 2009. Only cases with neoplastic cytology were included.

Results:

The overall frequency of normal, inadequate, neoplastic, and infective smears was 50%, 1.8%, 10.2%, and 38.3%, respectively. Most of the patients (67%) were in the postmenopausal age-group, with the mean age being 44.7±15.63 years. The commonest clinical signs/symptoms seen among the 102 patients with neoplastic gynecological lesions were vaginal discharge and abnormal bleeding (93/102;(91.2% and 62/102;60.7%). Of the 102 cases with neoplastic lesions 46 patients (45%) had low-grade squamous cell intraepithelial lesions (LSILs), 22 (21.5%) had high-grade squamous cell intraepithelial lesions (HSILs), 14 (13.7%) had squamous cell carcinoma, and 6 (5.8%) showed features of adenocarcinoma. Ten (9.8%) cases showed cytology of atypical squamous cells of undetermined significance (ASCUS) and four (3.9%) cases had atypical glandular cells of undetermined significance (AGUS).

Conclusion:

We conclude that cervical smear examination is well suited for diagnosing neoplastic disease. It is clear that cervical neoplastic lesions are becoming a problem in Pakistan.

Age-specific trends in black-white disparities in cervical cancer incidence in the United States: 1975-2009

BACKGROUND

Although overall cervical cancer incidence rates have decreased in both black and white women in the U.S. since the mid 1950s due to widespread screening, rates continue to be higher among blacks than among whites. However, whether this pattern differs by age is unknown.

METHODS

Cervical cancer cases (1975-2009, N=36,503) were obtained from nine Surveillance, Epidemiology, and End Results (SEER) Program registries. Age-standardized incidence rates for white and black women were calculated from 1975-1979 through 2005-2009 by age group (<50, 50-64, and ≥65 years). Rate ratios (RRs) and 95% confidence intervals (CIs) evaluated differences in rates for blacks vs. whites by age group and stage at diagnosis during 1975-1979 and 2005-2009.

RESULTS

Among women aged <50 years, the black-to-white disparity RR decreased from nearly two-fold (RR, 1.9; 95% CI, 1.7-2.1) during 1975-1979 to unity during 2005-2009 (RR, 0.9; 95% CI, 0.8-1.0). In contrast, rates remained significantly elevated for blacks vs. whites aged 50-64 years (RR, 2.4; 95% CI, 2.1-2.7 and 1.7; 95% CI, 1.5-2.0), and for those aged ≥65 years (RR, 3.3; 95% CI, 2.9-3.8 and 2.2; 95% CI, 1.9-2.7) during both time periods, although the disparities decreased over time. Similar disparities persisted for older black women with cervical cancer of all stages.

CONCLUSION

Disparities in cervical cancer incidence rates were eliminated for younger blacks vs. whites but persisted for blacks aged 50 years and older. Additional strategies are needed to increase follow-up and treatment of precancerous lesions among middle-aged and older black women.

Evaluation of therapeutic care delay among Latina- and European-American cervical cancer survivors

OBJECTIVES

Cervical cancer (CCA) ranks among the deadliest of cancers. Globally CCA claims 275,000 lives yearly. Severe delays, in cancer diagnostic or therapeutic care, that approach ≥ 60 days negatively affect survival and survivorship outcomes. This study investigated socioeconomic and healthcare system factors influencing therapeutic care delays among cervical cancer survivors (CCS).

METHODS

291 CCS (132 European-, 50 English-proficient (EP) Latina- and 109 limited English-proficient (LEP) Latina-Americans) were recruited from cancer registries. CCS retrospectively noted the days of delay in obtaining therapeutic care and reasons for delays.

RESULTS

CCS who were LEP Latina-Americans, had lower income and education reported severe therapeutic delays (≥ 60 days). LEP Latina-Americans experienced delays due to financial issues, doctor's delay, and healthcare system issues (p < 0.001). Doctor and healthcare system delays significantly influenced therapeutic care delay in the logistic regression model.

CONCLUSIONS

Healthcare system delays are primary contributors to ethnic differences in access to appropriately-timed care observed in this study. Healthcare professionals need to develop a fuller appreciation of the multilevel factors that contribute to healthcare barriers to better inform effective interventions to increase access to life saving care.

Correlating knowledge of cervical cancer prevention and human papillomavirus with compliance after colposcopy referral

OBJECTIVE

This study aimed to assess the impact of knowledge of cervical cancer biology and prevention as well as noncognitive measures on compliance with colposcopy referral in a high-risk population.

METHODS

Participants in a US cohort of women with human immunodeficiency virus (HIV) infection and at-risk comparison women completed behavior questionnaires and instruments measuring knowledge of cervical cancer prevention, depressive symptoms, trust in physicians, and perceived stress. Examinations including Pap tests also were conducted. Associations with compliance with resulting indicated colposcopy were assessed in multivariable models.

RESULTS

Of 326 women with indicated colposcopy, 222 (68%) were compliant with colposcopy referral and 104 (32%) were noncompliant. In multivariable analysis, better colposcopy compliance was associated with less education (odds ratio [OR] for compliance = 2.24, 95% confidence interval = 1.12-4.51 vs more than high school), previous abnormal Pap result (OR per previous abnormal Pap result = 1.08, 95% CI = 1.01-1.15), study site (OR for site with best vs worst compliance = 16.1, 95% CI = 2.91-88.6), and higher stress (OR for perceived stress scale 10 score >16 vs lower 3.25, 95% CI = 1.45-7.26).

CONCLUSIONS

Noncognitive factors and how sites manage abnormal Pap testing affect colposcopy compliance. Educational interventions alone are unlikely to improve colposcopy compliance in similar high-risk populations.

Immediate colposcopic evaluation in postmenopausal women with low-grade squamous intraepithelial lesion cytology

OBJECTIVE

To compare the final diagnosis among pre- and postmenopausal women with low-grade squamous intraepithelial lesion (LGSIL) cervical smear results.

DESIGN

Retrospective, comparative study.

SETTING

Departments of obstetrics and gynecology in two teaching and research hospitals.

POPULATION

Data were evaluated on 712 women with LGSIL between April 2005 and April 2011.

METHODS

Results from 129 postmenopausal women with LGSIL were compared with 583 premenopausal women with a similar LGSIL result with respect to sociodemographic data and histopathology.

MAIN OUTCOME MEASURES

Final clinicopathological diagnosis.

RESULTS

The mean age of the pre- and postmenopausal women was 37.2 and 52.5 years, respectively, and lesions of cervical intraepithelial neoplasia grade 2 or worse were detected by biopsy and/or endocervical curettage in 13.6 and 9.3%, respectively. There was no significant difference between the final diagnosis among pre- and postmenopausal women with LGSIL cytology (relative risk 1.43; 95% confidence interval 0.82-2.48; p= 0.19). Invasive cervical cancer was detected in three premenopausal (0.5%) and two postmenopausal women (1.6%).

CONCLUSIONS

Cervical pre-invasive and invasive disease rates were similar in pre- and postmenopausal women with LGSIL cytology. For this reason, LGSIL in postmenopausal women should be considered more seriously, and colposcopic evaluation may be as acceptable an option in the management of LGSIL in this group of patients as it is with premenopausal women.

Factors associated with time to colposcopy after abnormal Pap testing in HIV-infected women

BACKGROUND

HIV-infected women are at increased risk for cervical dysplasia and require timely follow-up after an abnormal Papanicolaou (Pap) test.

METHODS

This retrospective cohort study assessed the proportion of HIV-infected women with colposcopic evaluation after an abnormal Pap test. Time to colposcopy within 12 months after an abnormal Pap test was assessed with univariate and multivariate Cox proportional hazard modeling in a diverse cohort of HIV-infected women between October 1, 2003, and September 30, 2007.

RESULTS

One hundred seventy-seven subjects had an abnormal Pap test: 22 high-grade intraepithelial lesion (HSIL; 12%), 120 low-grade squamous intraepithelial lesion (LSIL; 68%), and 35 atypical squamous cells of undetermined significance, human papillomavirus positive (20%). One hundred twenty (68%) had follow-up colposcopy by 1 year. Decreased time to follow-up was associated with being married (HR 3.5, 95% CI 1.9-6.2), high school graduate or higher education level (HR 1.7, CI 1.2-2.6), HSIL Pap results (HR 2.8, CI 1.3-6.2), Pap testing performed by HIV nurse practitioner versus gynecology clinic (HR 1.7, 1.1-2.7), and CD4 count ≥500 cells/mm(3) (HR 1.8, CI 1.2-2.8), after adjusting for age, race/ethnicity, and LSIL Pap result. Private insurance was associated with decreased time to colposcopy in unadjusted, but not multivariate analysis. Drug use was not associated with time to follow-up colposcopy.

CONCLUSIONS

Almost one third of HIV-infected women did not have a follow-up colposcopy by 12 months after an abnormal Pap test. Since HIV-infected women are at particularly high risk for cervical cancer, these results are unacceptably poor. Identification of the barriers to appropriate follow-up and targeted interventions are necessary to improve timely follow-up for cytologic abnormalities in this high-risk population.

Timing of colposcopy after cervical cytologic abnormalities

OBJECTIVE

To examine the length of time from Pap test (index Pap) screening to follow-up colposcopy for women with abnormal Pap test results of low-grade squamous intraepithelial lesions (LSIL); atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesions (ASC-H); or high-grade squamous intraepithelial lesions (HSIL).

METHODS

We identified 4,824 women aged 18 to 64 years with the index Pap test results of LSIL, HSIL, or ASC-H from health insurance claims in a large U.S. health care organization and who had a routine Pap test in 2004. We used a survival regression model to estimate factors related to the length of time (days) from the index Pap test to a follow-up colposcopy.

RESULTS

The expected length of time from an abnormal Pap test to a colposcopy differed by age and Pap test result. For women with an ASC-H result, those who were older were more likely to delay colposcopy compared with the younger women. For women with LSIL and HSIL results, the timing of colposcopy did not differ by age; however, the time was shorter compared with ASC-H. We found that physician specialties, health care settings, and area-level racial and ethnic density were related to timing of receiving follow-up procedures after an abnormal index Pap test result.

CONCLUSION

Women with LSIL and HSIL received a colposcopy in 3-4 months, but women with ASC-H were more likely to receive the procedure at a later time.

Predictors of timely follow-up after abnormal cancer screening among women seeking care at urban community health centers

BACKGROUND

We sought to measure time and identify predictors of timely follow-up among a cohort of racially/ethnically diverse inner city women with breast and cervical cancer screening abnormalities.

METHODS

Eligible women had an abnormality detected on a mammogram or Papanicolaou (Pap) test between January 2004 and December 2005 in 1 of 6 community health centers in Boston, Massachusetts. Retrospective chart review allowed us to measure time to diagnostic resolution. We used Cox proportional hazards models to develop predictive models for timely resolution (defined as definitive diagnostic services completed within 180 days from index abnormality).

RESULTS

Among 523 women with mammography abnormalities and 474 women with Pap test abnormalities, >90% achieved diagnostic resolution within 12 months. Median time to resolution was longer for Pap test than for mammography abnormalities (85 vs 27 days). Site of care, rather than any sociodemographic characteristic of individuals, including race/ethnicity, was the only significant predictor of timely follow-up for both mammogram and Pap test abnormalities.

CONCLUSIONS

Site-specific community-based interventions may be the most effective interventions to reduce cancer health disparities when addressing the needs of underserved populations.

A theory-based approach to understanding follow-up of abnormal Pap tests

We applied a general theoretical framework to understand intentions to attend recommended follow-up for abnormal Pap results. Participants were 338 women attending university-affiliated clinics. Intention was associated with favorable attitudes toward follow-up (OR = 5.3); perceiving attending follow-up as consistent with one's self-concept (OR = 3.0); self-efficacy (OR = 1.8); and believing one would be told exactly what is wrong (OR = 1.3). Intention was negatively associated with believing the problem could be avoided by not returning for follow-up (OR = 0.75). Beliefs, affect and attitudes differed by race and ethnicity (all p < .05). Attendance at follow-up was related to attitude and self-concept (both p < .05). Results have implications for theory development and patient education.

Preditores de não aderência ao seguimento preconizado para mulheres com lesão intraepitelial escamosa de alto grau (HSIL)

O câncer de colo uterino é um tumor de natureza multifatorial que persiste como um importante problema de saúde pública. Aderência à linha de cuidado é fator associado ao controle desse câncer. O objetivo deste estudo foi avaliar fatores associados à "Não aderência" ao seguimento preconizado para mulheres com lesão intraepitelial de alto grau (HSIL), atendidas em um serviço de saúde da Baixada Fluminense, no Rio de Janeiro. Este estudo do tipo coorte retrospectivo incluiu mulheres rastreadas por citologia, matriculadas entre 01/01/2002 e 31/12/2005 e submetidas à colposcopia. A coleta de dados terminou em 31/12/07. Foram revisados 1496 prontuários e identificadas 641 mulheres elegíveis com diagnóstico de HSIL obtido por excisão da zona de transformação do colo uterino. Após a aplicação dos critérios de exclusão, a população de estudo foi constituída por 537 (84%) mulheres, classificadas em dois grupos: "não aderentes" (29,4%), que abandonaram o seguimento, e "aderentes" (70,6%), que permaneceram no seguimento até a alta. A análise estatística foi realizada pelo teste do qui-quadrado, teste t e regressão logística. O modelo final incluiu as variáveis: ser fumante (OR 1,72), dona de casa (OR 1,56), ter realizado o exame com o uso do vídeo-colposcópio (OR 1,80), idade (OR 0,97) e antecedente de três ou mais gestações (OR 0,49). O estudo revelou um perfil de vulnerabilidade apontando para determinantes de ordem individual e organizacional. Estratégias para melhorar a aderência ao seguimento devem contemplar medidas dirigidas a fatores modificáveis do estilo de vida, como o tabagismo, e estruturais característicos dos serviços de saúde da região.

Assessing analgesic regimen adherence with the Morisky Medication Adherence Measure for Taiwanese patients with cancer pain

The purposes of this study were (1) to examine the psychometric properties of the Taiwanese version of the Morisky Medication Adherence Measure (MMAM), including its validity and reliability, (2) to investigate levels of analgesic regimen adherence, and (3) to explore the predictors of adherence to the analgesic regimen in a sample of Taiwanese cancer patients with pain. One hundred thirty-five patients receiving analgesics for cancer pain participated in this study. Instruments consisted of the Taiwanese version of the MMAM, the Barriers Questionnaire-Taiwan form, the Chinese version of the Brief Pain Inventory, the American Pain Society Outcome Questionnaire, Karnofsky Performance Status, and a demographic questionnaire. Analgesic use ratios were calculated. The Taiwanese version of the MMAM had good psychometric properties for measuring adherence with the analgesic regimens taken by Taiwanese cancer pain patients. Reliability was supported by good internal consistency Cronbach alpha and test-retest coefficients. Validity was corroborated by good known group validity, construct validity, and criterion-related validity. The majority of the patients (51%) showed low levels of medication adherence. The significant predictors for the medication adherence score were age, the Barriers Questionnaire score, and satisfaction with pain management by clinicians after entering pain severity, pain interference with daily life, age, gender, education, types of analgesics used, functional status, and satisfaction with pain management as independent variables. The model accounted for 63% of the variance in the medication adherence score. The Taiwanese version of the MMAM shows excellent reliability and validity. The use of this reliable, valid, simple, and easily administered tool can improve communication between patients and clinicians about use of analgesics and further improve the analgesic regimen adherence.

Adherence to recommendations for follow-up to abnormal Pap tests

OBJECTIVE

To evaluate whether timely adherence rates differ by race among women with abnormal Pap tests participating in a cost-free or reduced-cost program.

METHODS

Eligible subjects included women aged 47-64 years who received a referral for follow-up care after an abnormal Pap test from 1999 to 2002 in South Carolina (n=330). Adherence was measured as days to receipt of follow-up care after an abnormal Pap test. Cox proportional hazards modeling was used to estimate risk factors associated with time to adherence within 60 and 365 days by race.

RESULTS

African-American and non-Hispanic white women had similar adherence to follow-up. Among white women, those with high-grade lesions were less likely to adhere in a timely manner relative to those with low-grade lesions (hazard ratio 0.6, 95% confidence interval [CI] 0.4-1.0). For African-American women, rural residence (hazard ratio: 0.5, 95% CI 0.2-0.9) and history of abnormal Pap tests (hazard ratio 0.6, 95% CI 0.3-1.0) were associated with decreased adherence, whereas less education (hazard ratio 2.3, 95% CI 1.3-3.9) was associated with increased adherence.

CONCLUSION

Adherence rates do not differ by race. However, risk factors for adherence within race are variable. Interventions tailored to the differential needs of racial and ethnic groups may prove effective toward increasing timely adherence rates.
