Therapy Guidance by Vaginal Smears of Pregnant Women With Preterm Complications in Correlation With Maternal and Neonatal Outcome: A Retrospective Analysis. In Vivo 2023; 37:1211-1218. [PMID: 37103084 DOI: 10.21873/invivo.13169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 03/06/2023] [Accepted: 03/07/2023] [Indexed: 04/28/2023]
Abstract
BACKGROUND/AIM This retrospective cohort study enrolled hospitalized women with 24+0 to 33+6 gestational weeks with conditions associated with preterm birth. We evaluated the ability of vaginal swab isolates to guide antibiotic management decisions in the setting of threatened preterm towards a clinical advantage, i.e., longer delay between diagnosis and birth, better neonatal outcomes. PATIENTS AND METHODS Vaginal swabs were obtained from all patients and antibiotic resistance profiles determined in case of growth. The cohort was divided into two groups: the antibiogram-noncongruently managed Group 1 and the antibiogram-congruently managed Group 2. These groups were compared in regard to multiple maternal and neonatal endpoints. RESULTS In total, 698 cases were analyzed - 224 in Group 1 and 474 in Group 2. Antibiotics were ordered/continued by the treating physician in 138 cases (138/698; 19.8%) upon review of vaginal swab cultures results. Forty-five among them (32.6%) received antibiotics inactive against the isolated bacteria. 335 (25.4%) patients had only normal vaginal flora, and 95.6% of them had not received antibiotics. Facultatively pathogenic microorganisms were isolated in 52% patients. Only 5% of the neonates had bacterial isolates identical to those of their mothers. There were no significant differences in outcomes between Group 1 and Group 2. CONCLUSION No association was found between a swab-result-guided antibiotic management protocol and maternal or fetal outcome in the setting of preterm birth risk between 24 and 34 gestational weeks. These findings underline the importance of critical rethinking the frequency of vaginal smears and fine-tuning the indications for antibiotic treatment.

Characteristics associated with Lactobacillus iners-dominated vaginal microbiota. Sex Transm Infect 2021; 98:353-359. [PMID: 34497114 DOI: 10.1136/sextrans-2020-054824] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Accepted: 08/29/2021] [Indexed: 12/26/2022] Open
Abstract
OBJECTIVE The protective role of Lactobacillus iners in the vaginal microbiota has been questioned. Recent studies have shown that L. iners is the dominating taxon in a large subset of women worldwide. The aim of this study was to identify sociodemographic, behavioural and clinical variables associated with L. iners-dominated community state type (CST) III in Brazilian women of reproductive age. PARTICIPANTS AND METHODS This study leveraged microbiota compositional data generated by sequencing of the V3-V4 16S rRNA gene from vaginal samples collected from 442 participants enrolled in a previous cross-sectional study that included 609 women in five geographical regions of Brazil. A total of 167 (27.4%) participants were excluded from the current study as they did not present a Lactobacillus-dominated vaginal microbiota. Data on sociodemographic and behavioural characteristics of the study population were obtained through face-to-face interviews. Participants were assigned to two study groups: those with L. iners-dominated CST III (n=222) and those with three distinct CSTs (I, II or V) dominated by another Lactobacillus spp. (n=220). Logistic regression analysis using a stepwise method was performed to test association between CST III and participants' characteristics, considering their OR and 95% CIs. RESULTS Among the population characteristics assessed, L. iners-dominated CST III was independently associated with having two or more sexual partners (OR 3.27; 95% CI 1.50 to 7.11) and microscopic detection of Candida sp. on vaginal smears (OR 2.24; 95% CI 1.02 to 4.89). Other characteristics were inversely associated with CST III, including condom use (OR 0.59; 95% CI 0.38 to 0.91), higher educational level (OR 0.61; 95% CI 0.41 to 0.91) and diet containing milk/dairy intake (OR 0.43; 95% CI 0.20 to 0.90). CONCLUSION Unprotected sex practices, number of sexual partners and lower educational levels may be useful for identifying women with L. iners-dominated microbiota and its suboptimal protective properties. L. iners microbiota does not seem to provide optimal protection against Candida sp. colonisation, warranting further investigation.

Abstract
Background β-Catenin mediates cellular adhesion and the Wnt/β-catenin signaling mechanism, thereby controlling cell proliferation and differentiation. Studies of endometrial tissue suggest that there are differences in β-catenin expression during the course of regular menstrual cycles. However, differences in expression in squamous epithelial cells between the proliferative and secretory phases have hitherto remained unknown. Objectives To localize β-catenin in squamous epithelial cells in cervicovaginal smears during the course of regular menstrual cycles. Methods In this observational study, smears were taken from women (n = 102) with various gynecological complaints. Squamous epithelial cells were stained using a Papanicolaou method to evaluate their cytology and any infection. An anti-β-catenin antibody was used to localize immunoreactivity in the cell membrane, cytoplasm, and/or nucleus. Results Women with a regular menstrual cycle (n = 62) were divided into 2 groups: those in a proliferative phase (26/62, 42%) and those in a secretory phase (36/62, 58%). Cytoplasmic and nuclear β-catenin immunoreactivity was observed prominently in the proliferative phase (19/26, 73%), whereas low-level β-catenin immunoreactivity was seen in the secretory phase (9/36, 25%). Compared with the secretory phase, the mean H-scores for β-catenin immunoreactivity in the proliferative phase were significantly increased in the membrane (P = 0.039), the cytoplasm (P < 0.001), and the nucleus (P = 0.033). By contrast, β-catenin immunoreactivity was reduced from parabasal to superficial cells in both the proliferative and secretory phases. Conclusions Cytoplasmic and/or nuclear β-catenin immunoreactivity may indicate that the activity of the Wnt/β-catenin signaling pathway is cycle dependent.

Follow-up of women with inadequate Pap smears: a prospective cohort study. SAO PAULO MED J 2015; 133:20-7. [PMID: 25626852 PMCID: PMC10496621 DOI: 10.1590/1516-3180.2013.7070004] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2013] [Accepted: 02/10/2014] [Indexed: 11/21/2022] Open
Abstract
CONTEXT AND OBJECTIVE Inadequate Pap smears do not provide satisfactory cell samples for evaluation, thus making it more difficult to detect cervical cytological abnormalities. The objective of this study was to determine the cytological and histological follow-up results from women with inadequate smear reports in primary healthcare centers in Santiago, Chile 2010-2011. DESIGN AND SETTING Prospective cohort study at primary healthcare clinics in Santiago, Chile. METHODS The population was taken from the "Cito-Expert" database of 2010. The data were then organized according to the cytological and histological follow-up results of 2,547 women with inadequate cervical cytological reports over the 12-month period. The samples were assigned to groups based on the cause of inadequacy (smears with endocervical cells alone; insufficient, hemorrhagic, inflammatory or poorly fixed samples; insufficient and hemorrhagic samples; or insufficient and inflammatory specimens). The data were analyzed using the "conditional probability tree diagram" and descriptive statistics. RESULT Half of the women (n = 1,285) met the requirements of the Ministry of Health for repeating these inadequate smears, and 1,104 of these women had normal cytological results (85.9%). The detection rate for cervical lesions according to group ranged from 0% (smears with endocervical cells alone or insufficient and hemorrhagic specimens) to 4.1% (poor fixation). CONCLUSION The large proportion of normal results justifies revision of the current clinical guidelines. The results showed that it is not necessary to repeat the Pap test early on, with the exception of inadequate hemorrhagic and inflammatory cytological results.

A retrospective study on cervical intraepithelial lesions of low-grade and undetermined significance: evolution, associated factors and cytohistological correlation. SAO PAULO MED J 2014; 132:92-6. [PMID: 24714989 PMCID: PMC10896570 DOI: 10.1590/1516-3180.2014.1322579] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2012] [Revised: 05/21/2013] [Accepted: 06/14/2013] [Indexed: 11/22/2022] Open
Abstract
CONTEXT AND OBJECTIVES Cervical cancer is an important cause of morbidity and mortality throughout the world. There is some controversy about the factors that may be associated with infection by the human papillomavirus (HPV) that may favor or protect against evolution from a low-grade intraepithelial lesion to a high-grade intraepithelial lesion or invasive neoplasia. The objective here was to evaluate the evolution of low-grade intraepithelial lesions and squamous or glandular lesions of undetermined significance, the associated factors and cytohistological correlations. DESIGN AND SETTING Retrospective study conducted in a public tertiary-level university hospital. METHODS Information was obtained by reviewing patient records and/or colposcopy reports. A statistical analysis was performed using logistic regression, calculating the odds ratio and applying chi-square tests. RESULTS Of the 3390 patients, 409 evolved to high-grade intraepithelial lesions, of which 354 had an initial diagnosis of HPV infection, 27 of squamous atypia of undetermined significance, 22 of low-grade intraepithelial lesions with or without cytological diagnosis of infection by associated HPV and six of glandular cell atypia of undetermined significance. CONCLUSIONS Lactobacillus sp and bacterial vaginosis on the smears, smoking and immunodepression were factors associated with evolution. A single partner, use of hormonal contraceptives, lower parity, age and a cytological diagnosis of cytolytic vaginosis, T. vaginalis, Candida sp or cocci were factors associated with protection. With regard to cytohistological correlation, there was a 74.08% agreement among patients with high-grade lesions and a biopsy obtained during the same period.

Abstract
PURPOSE To explore through descriptive comparative analysis an alternative method of pelvic examination to increase patient comfort. DATA SOURCES Sixty-two participants were recruited from a convenience sample of patients at an ambulatory women's healthcare clinic operated by a teaching hospital in the Southwest United States. Twenty-five were examined using the conventional pelvic examination technique; 37 with a new technique that we call the Rad technique, named after a co-author of the study. Three women's health nurse practitioners were trained in both methods and alternated the exam technique used. Visualization of the cervix was measured by clinician responses to the Speculum Exam Questionnaire for Clinicians; level of pain was determined from patient responses to the Wong-Baker FACES Pain Rating Scale. Results were analyzed using a t-test for independent samples. Pain was further analyzed using chi-square test of association. CONCLUSIONS Although the relationship between the variables of visualization and pain was not statistically significant, 16% of women in the conventional technique group reported vaginal pain compared with 5.4% in the Rad technique group. IMPLICATIONS FOR PRACTICE Changing from the conventional pelvic examination to the Rad technique may create a more positive patient experience and thereby engage more women in recommended in gynecological health care.

Abstract
Human papilloma virus can infect any mucous of the body and can cause cancer of the uterine cervix. This suggests recommending the Papanicolaou smear combined with a test for detection of human papillomavirus with a frequency interval of 3 years, since it grants greater information and fidelity to the result. The detection studies should begin at the age of 21 years and should stop at 65 years age. Until recently specific treatments did not exist to treat human papilloma virus, but recently some drugs that have demonstrated good effectiveness in curing the infection of human papilloma virus. One example is glycirrhicinic acid, which has demonstrated fewer adverse effects, as well as the possibility that its systemic employment allows treatment of lesions that are difficult to approach. The medical recommendations should be in constant revision, since a clinical trial can modify the interpretation of what is necessary to individualize each patient's treatment.

Abstract
The Desert hamster, Phodopus roborovskii, is one of the lesser-known laboratory animal models and therefore knowledge of its reproductive system and physiology is limited. This study investigated the time course of vaginal and behavioural oestrus cycles by means of vaginal smear cytology, serum luteinizing hormone (LH) levels, wheel-running activity patterns, and pairing tests. The oestrus cycle lasts between four and six days and follows a pattern rather similar to that described for other rodent species. An important finding of this study is the existence of a fifth cycle stage between pre-oestrus and oestrus, the so-called early oestrus. Early oestrus differs from pre-oestrus by a complete lack of leucocytes in the vaginal cytology and a dramatic increase of serum LH levels just before activity onset. The early oestrus stage lasts 4-6 h, but was not observed in every female. When present it affects the length of the whole oestrus cycle. With early oestrus the pre-oestrus stage lasts only 14-18 h and the total length of the oestrus cycle length is four days. Without early oestrus, the pre-oestrus is prolonged to 18-36 h and the oestrus cycle length varies between four and six days. Desert hamsters showed only subtle oestrus-correlated changes in wheel-running activity, i.e. they failed to show the characteristic scalloping of activity onset, but showed prolonged activity during early oestrus. Pairing tests revealed characteristic changes in the relative frequencies of socio-positive, neutral, aggressive and sexual behaviour during the course of the oestrus cycle, with an elevated level of sexual behaviour during oestrus.

Abstract
Objective The aim was to review the international literature on the validity of self-report of cervical cancer screening, specifically of studies that made direct comparisons among women with and without social disadvantage, based on race/ethnicity, foreign-born status, language ability, income, or education. Method The databases of Medline, EBM Reviews, and CINAHL from 1990 to 2011 were searched using relevant search terms. Articles eligible for data extraction documented the prevalence of cervical cancer screening based on both self-report and an objective measure for women both with and without at least one measure of social disadvantage. The report-to-record ratio, the ratio of the proportion of study subjects who report at least one screening test within a particular time frame to the proportion of study subjects who have a record of the same test within that time frame, was calculated for each subgroup. Results Five studies met the extraction criteria. Subgroups were based on race/ethnicity, education, and income. In all studies, and across all subgroups, report-to-record ratios were greater than one, indicative of pervasive over-reporting. Conclusion The findings suggest that objective measures should be used by policymakers, researchers, and public-health practitioners in place of self-report to accurately determine cervical cancer screening rates.

Colposcopic triage methods for detecting cervical intraepithelial neoplasia grade 3 after cytopathological diagnosis of low-grade squamous intraepithelial lesion: a systematic review on diagnostic tests. SAO PAULO MED J 2012; 130:44-52. [PMID: 22344359 PMCID: PMC10906687 DOI: 10.1590/s1516-31802012000100008] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2011] [Revised: 01/31/2011] [Accepted: 09/23/2011] [Indexed: 11/22/2022] Open
Abstract
CONTEXT AND OBJECTIVE The age-stratified performance of the oncogenic HPV-DNA (human papillomavirus deoxyribonucleic acid) test for triage of low-grade squamous intraepithelial lesions (LSIL) requires investigation. The objective of this study was to evaluate and compare the age-stratified performance (cutoff point: 35 years) of oncogenic HPV-DNA testing and repeated cytological tests, for detecting cervical intraepithelial neoplasia grade 3 (CIN3), in order to triage for LSIL. DESIGN AND SETTING Systematic review. Studies were identified in nine electronic databases and in the reference lists of the articles retrieved. METHODS The eligibility criteria consisted of initial cytological findings of LSIL; subsequent oncogenic HPV-DNA testing and repeated cytological tests; and CIN3 detection. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS) guidelines were used for quality assessment. Qualitative information synthesis was performed. RESULTS Out of 7,776 studies, 284 were identified as pertinent and three fulfilled the eligibility criteria. The CIN3 prevalence ranged from 6% to 12%. The HPV-DNA positivity rate ranged from 64% to 83%; sensitivity for CIN3 detection ranged from 95.2% to 100%; and specificity was available in two studies (27% and 52%). The sensitivity of repeated cytological tests, in relation to the threshold for atypical squamous cells of undetermined significance (ASCUS), was available in two studies (33% and 90.8%); and specificity was available in one study (53%). CONCLUSIONS Currently, there is no scientific evidence available that would prove that colposcopic triage using oncogenic HPV-DNA testing to detect CIN3 performs better than repeated cytological tests, among women with LSIL aged 35 years and over.

Abstract
A considerable number of adult Korean women avoid a Pap smear due to fear and discomfort of the pelvic examination. A reliable but noninvasive and comfortable screening method would considerably increase the participation rate. To evaluate the clinical efficacy of urine-based human papillomavirus (HPV) detection by oligonucleotide microarray, the results of HPV test from matched cervical swab specimens were compared. HPV DNA was detected in 70 of 100 cervical samples. HPV 16 was the most prevalent type (38/70), followed by types 18, 58, 52, 33, 35, 31, and 51. HPV DNA was identified in 47 of 90 urine samples. HPV 16 was the most prevalent type (30/45), followed by types 18, 52, 35, 51, 58, 33, and 56. The HPV detection rates of the cervical swabs increased in accordance with the severity of the cytologic and histologic diagnosis. The type specific agreement of HPV DNA tests between cervical swabs and urine was good in HPV 16 (kappa index=0.64 [95% CI: 0.50-0.79]), 18, 52, and 58 and fair in HPV 33 and 35. We propose that a urine HPV test is a valuable adjunctive method for a conventional Pap smear and can be used in population screening for cervical cancer in countries where it is difficult to obtain colposcopic specimens for cultural or religious reasons.

Abstract
PURPOSE We assessed whether increased cancer screening rates that were observed with Cancer Screening Office Systems (Cancer SOS) could be maintained at 24 months' follow-up, a period in which clinics were expected to be largely self-sufficient in maintaining the intervention. METHODS Eight primary care clinics serving disadvantaged populations in Hills-borough County, Fla, agreed to take part in a cluster-randomized experimental trial. Charts of independent samples of established patients aged 50 to 75 years were abstracted, with data collected at baseline (n = 1,196) and at 24 months' follow-up (n = 1,296). Papanicolaou (Pap) smears, mammography, and fecal occult blood testing were assessed. RESULTS At 24 months of follow-up, intervention patients had received a greater number of cancer screening tests (mean 1.17 tests vs 0.94 tests, t test = 4.42, P <.0001). In multivariate analysis that controlled for baseline screening rates, secular trends, and other patient and clinic characteristics, the intervention increased the odds of mammograms slightly (odds ratio [OR]) = 1.26; 95% confidence interval [CI], 1.02-1.55; P = .03) but had no effect on fecal occult blood tests (OR = 1.17; 95% CI, 0.92-1.48; P =0.19) or Pap smears (OR = 0.88; 95% CI, 0.0.68-1.15; P = .34). CONCLUSIONS The Cancer SOS intervention had persistent, although modest, effects on screening at 24 months' follow-up, an effect that had clearly diminished from results reported at 12 months' follow-up. Further study is needed to develop successful intervention strategies that are either self-sustaining or that are able to produce long-term changes in screening behavior.

Abstract
BACKGROUND Cervical cancer remains a significant yet preventable disease despite the widespread availability of Pap test screening, which detects cervical cancer and its precursor lesions. The aims of this study were to: i) estimate and compare age- and hysterectomy-adjusted Pap test rates across the 37 Ontario public health units (PHUs), and ii) explore the association between several factors and Pap test rates (at the ecological level). METHODS Cytobase, an Ontario Pap test registry, captures more than 80% of all Pap tests in Ontario. Cytobase was used to determine Pap test rates adjusted for age, hysterectomy and Cytobase coverage for the year 2001. Multiple linear regression analyses were used to evaluate the relationship between Pap test rates and various factors at an ecological level, RESULTS Age-, hysterectomy- and Cytobase-adjusted one-year Pap rates ranged from 11.6% to 73.9% among PHUs. The overall rate for Ontario was 40.7%. Multivariate analyses indicated that the presence of a teaching hospital was associated with higher Pap test rates. CONCLUSION One-year Pap test rates varied greatly across the 37 public health units in Ontario. Pap test rates determined using Cytobase were lower than self-reported rates obtained from the Canadian Community Health Survey, possibly due to "over-reporting". In general, women were not screened as frequently as recommended by the Ontario Cervical Screening Program. A positive association was observed between Pap test rates and the presence of a teaching hospital. Data quality issues limit the ability to monitor cervical screening. A provincial registry would address these issues.

Abstract
The goal of this study was to evaluate the cytomorphologic features of histologically confirmed uterine papillary serous carcinomas (UPSC) of the endometrium. We reviewed cervicovaginal smears from 12 patients with UPSC who had done their cervical smears at six months to a year earlier before the time of diagnosis; nine smears (75%) were diagnosed as positive for malignancy and three smears (25%) were diagnosed as negative. The cervical smears of patients with UPSC revealed frequent papillary clusters that were composed of large pleomorphic tumor cells with prominent nucleoli in a background of necrosis. Other findings revealed from the tests were relatively frequent single malignant cells and bare nuclei. Although the Pap smear is not a sensitive screening test for endometrial carcinoma, we could depend on it to reveal the cytologic features of UPSC which are fairly characteristic and reliable for a preoperative diagnosis of UPSC. Preoperative identification of this poor prognostic variant of endometrial carcinoma may influence the surgical management of these cases and the choice of adjuvant therapy.

Abstract
BACKGROUND We assessed the efficacy of the Cancer Screening Office Systems (Cancer SOS), an intervention designed to increase cancer screening in primary care settings serving disadvantaged populations. METHODS Eight primary care clinics participating in a county-funded health insurance plan in Hillsborough County, Fla, agreed to take part in a cluster-randomized experimental trial. The Cancer SOS had 2 components: a cancer-screening checklist with chart stickers that indicated whether specific cancer-screening tests were due, ordered, or completed; and a division of office responsibilities to achieve high screening rates. Established patients were eligible if they were between the ages of 50 and 75 years and had no contraindication for screening. Data abstracted from charts of independent samples collected at baseline (n = 1,196) and at a 12-month follow-up (n = 1,237) was used to assess whether the patient was up-to-date on one or more of the following cancer-screening tests: mammogram, Papanicolaou (Pap) smear, or fecal occult blood testing (FOBT). RESULTS In multivariate analysis that controlled for baseline screening rates, secular trends, and other patient and clinic characteristics, the intervention increased the odds of mammograms (odds ratio [OR] = 1.62, 95% confidence interval [CI], 1.07-9.78, P = .023) and fecal occult blood tests (OR = 2.5, 95% CI, 1.65-4.0, P <.0001) with a trend toward greater use of Pap smears (OR = 1.57, 95% CI, 0.92-2.64, P = .096). CONCLUSIONS The Cancer SOS intervention significantly increased rates of cancer screening among primary care clinics serving disadvantaged populations. The Cancer SOS intervention is one option for providers or policy makers who wish to address cancer related health disparities.

Abstract
BACKGROUND We wanted to determine whether variations exist in use of a chaperone during the performance of a pelvic examination by family physicians. METHODS A self-administered questionnaire was mailed to 5,000 randomly selected active members of the American Academy of Family Physicians. RESULTS There were 3,551 survey responses (71% response rate) and 2,748 useable questionnaires. Most respondents (75.4%) reported routinely using a chaperone in the room during the collection of a Papanicolaou (Pap) smear. Significantly (P < .00001) more male physicians (84.1%) than female physicians (31.4%) reported using a chaperone. Physicians reporting routine use of a chaperone were significantly younger (P = .01) and did fewer Pap smears per month (P < .00001). Regional reporting of chaperone use varied significantly (P < .00001), with 71.6% reporting use in the Northeast, 89.0% in the South, 65.7% in the Midwest, and 72.4% in the West. CONCLUSION Family physicians vary considerably in the reported use of a chaperone during the collection of a Pap smear. The variation could reflect different regional or local norms, efficiency or resource issues in high-volume clinical settings, or other interpersonal factors. These issues need to be explored in more depth.

Abstract
OBJECTIVE To determine if women would have higher breast and cervical cancer screening rates if lay health advisers recommended screening and offered a convenient screening opportunity. DESIGN Controlled trial. SETTING Urban county teaching hospital. PARTICIPANTS Women aged 40 years and over attending appointments in several non-primary-care outpatient clinics. INTERVENTIONS Lay health advisers assessed the participants' breast and cervical cancer screening status and offered women in the intervention group who were due for screening an appointment with a female nurse practitioner. MEASUREMENTS AND MAIN RESULTS Screening rates at baseline and at follow-up 1 year after the intervention were determined. At follow-up, the mammography rate was 69% in the intervention group versus 63% in the usual care group (p = .009), and the Pap smear rate was 70% in the intervention group versus 63% in the usual care group (p = .02). In women who were due for screening at baseline, the mammography rate was 60% in the intervention group versus 50% in the usual care group (p = .006), and the Pap smear rate was 63% in the intervention group versus 50% in the usual care group (p = .002). The intervention was effective across age and insurance payer strata, and was particularly effective in Native American women. CONCLUSIONS Breast and cervical cancer screening rates were improved in women attending non-primary-care outpatient clinics by using lay health advisers and a nurse practitioner to perform screening. The effect was strongest in women in greatest need of screening.
