Does the system of Papanicolaou test nomenclature affect the rate of referral for colposcopy? A survey of family physicians.

OBJECTIVE: To determine whether a new system of Papanicolaou test nomenclature (the Bethesda system) or other physician variables influence recommendations for colposcopy and biopsy for women with borderline to moderately abnormal Papanicolaou test results. We hypothesized that physician demographic and practice variables, in addition to Papanicolaou test nomenclature, would influence recommendations for colposcopy. DESIGN: A survey was mailed to a random sample of 510 active members of the American Academy of Family Physicians. PARTICIPANTS: Three hundred thirty-five (66%) of the eligible physicians responded, representing all 50 states. Of those in active practice, 78% were in private practice, with a mean age of 44 years and a mean time in practice of 10 years. Ninety-three percent of respondents in active practice performed Papanicolaou tests. MAIN OUTCOME MEASURE: Rates of recommendation for colposcopy and biopsy in response to abnormal Papanicolaou test reports framed by a single clinical scenario. RESULTS: Physicians recommended colposcopy more often when the Bethesda nomenclature system was used to describe the results of the Papanicolaou test. These differences were significant for four specific Papanicolaou smear pairs. Inclusion of recommendations for further evaluation strongly influenced physicians to recommend colposcopy. In multivariable analyses, demographic and practice variables were not associated with recommendations for colposcopy. CONCLUSIONS: The Bethesda system of nomenclature, when compared with a traditional descriptive nomenclature system, influenced family physicians to recommend colposcopy and biopsy more often for abnormal Papanicolaou test results presented in a clinical scenario. Greater utilization of technology and higher medical care costs may result from use of the Bethesda system. Guidelines for evaluation of abnormal Papanicolaou test results are needed for use in conjunction with the Bethesda system guidelines for Papanicolaou test reports.

[Colposcopy: the value of HPV testing in clinical practice].

The indications for colposcopy have changed recently because of the new Bethesda terminology, the introduction of HPV testing in clinical practice, and the latest consensus guidelines on management of patients with an abnormal cervical cytological test. Colposcopy remains the reference technique to assess patients with abnormal cytological test results, especially those with ASC-H, LSIL, HSIL, and AGC. In women with an ASC-US result, colposcopic examination of only those who test positive for high-risk HPV increases the specificity of the technique. When liquid-based cytology is used, HPV DNA testing is the preferred approach in these women. In primary screening using combined cytology and HPV DNA testing in women over the age of 30, colposcopy is indicated in patients with normal cytology and two HR HPV DNA positive tests performed at a nine month interval. For the follow up of untreated patients with ASC-US/LSIL and CIN I, colposcopy carried out at one year after a single HR HPV DNA positive test is as sensitive as colposcopy after two or three abnormal cytology tests. After excision or conization in patients with high-grade CIN, colposcopy after a single HR HPV DNA positive test is as sensitive as cytology testing and colposcopy at six months. Therapeutic decisions must not be based solely on the results of HPV DNA testing except in specific cases.

Repeating cytology at initial colposcopy does not improve detection of high-grade abnormalities: a retrospective cohort study of 6595 women.

OBJECTIVE: To determine if repeating a smear improves detection of high-grade pre-invasive or invasive disease of the cervix compared with women who do not have a repeat smear at the time of the initial colposcopic assessment for referral of an abnormal smear. DESIGN: Retrospective cohort study. SETTING: All Wales Colposcopy database. POPULATION: The cohort included women referred for colposcopy with an abnormal smear result, who were seen between 1st January 2002 and 31st December 2002. METHOD: The management of the group of women who had a repeat smear was compared with the group who did not have a repeat smear test at their first visit. Confidence interval analysis was used to compare results between the two groups. MAIN OUTCOME MEASURE: The positive predictive value and sensitivity of the repeat smear to predict outcome, compared to the referral smear in cases where a smear was not repeated at the colposcopy clinic. RESULTS: 3505 cases (54.0%) did not have a repeat smear at initial colposcopy, whereas 2990 (46%) did. There was a significantly higher rate of referral for low-grade dyskaryosis in the group who had repeat smear testing. The median time interval from the referral smear to the first colposcopy was 49 days for both groups. The specificity and positive predictive value for high-grade lesions were significantly higher in the repeat smear results. The sensitivity was significantly lower, and a high-grade lesion would have been missed with the repeat smear in 14.0% of all referrals. CONCLUSIONS: Colposcopists appeared more inclined to repeat smears for low-grade referrals. The time interval from the referral smear to colposcopy did not appear to influence this decision. A repeat smear test at the first colposcopy visit will detect less high-grade pre-invasive or invasive disease than the initial referral smear.

Residency training in colposcopy: a survey of program directors in obstetrics and gynecology and family practice.

OBJECTIVE: Our goal was to identify how colposcopy is being taught to residents in obstetrics and gynecology and family practice programs and to see if the program directors think their residents receive sufficient clinical exposure to be adequately trained in colposcopy. STUDY DESIGN: A 30-question survey was sent to all obstetrics and gynecology and family practice residency program directors. The survey included questions about the didactic nature of the colposcopy curriculum, the type of supervision, how resident skills are evaluated, estimates of the numbers and types of patients evaluated, the numbers and types of procedures being done by each resident, and the program director's perception of residents' competence in colposcopy. RESULTS: The overall response rate was 485 of 752 program directors (64.5%). Significantly fewer family practice than obstetrics and gynecology program directors thought they had adequate numbers of colposcopy patients to train their residents. By their program directors' estimates, 86% of family practice residents evaluate 10 or fewer patients with high-grade lesions (versus 16.5% of obstetrics and gynecology residents); 51.4% evaluate 10 patients or fewer with low-grade lesions (versus 6.7% of obstetrics and gynecology residents), and 40.6% evaluate 10 patients or fewer with atypical squamous cells of undetermined significance (versus 3% of obstetrics and gynecology residents). Experience with vulvar disease is also limited. Program directors thought their residents' colposcopy skills were roughly comparable with their general obstetrics and gynecology skills. CONCLUSIONS: It is possible that many program directors underestimate the number of colposcopic examinations required to achieve and maintain colposcopic skills. Many training programs have insufficient clinical volume to properly train residents in colposcopy.

Should liquid-based cytology be repeated at the time of colposcopy?

OBJECTIVE: To evaluate the usefulness of repeated liquid cytology at the time of colposcopy. MATERIALS AND METHODS: We screened 5,100 women with liquid-based cytology and human papillomavirus (HPV) DNA testing. Women with any abnormal cytology result including atypical squamous cells of undetermined significance (ASCUS) or a positive high-risk HPV DNA test result were referred for colposcopy. One thousand three hundred thirty-three women returned for colposcopy with repeated cytology and cervical biopsy. RESULTS: Twenty-one women had less than high-grade squamous intraepithelial lesion (HSIL) screening cytology and cervical biopsy results; however, their repeated cytology at the colposcopy visit revealed HSIL, and excisional treatment was recommended. Repeated cytology at colposcopy significantly changed the clinical management for 1.6% (21) of 1,333 women. CONCLUSIONS: As an adjunct test to colposcopy, liquid cytology was similar to conventional cytology. Given current practice patterns, repeated liquid cytology at the time of colposcopy is rarely clinically useful.

Colposcopy and treatment of cervical intra-epithelial neoplasia: are national standards achievable?

OBJECTIVE: To assess whether consensus based national standards for colposcopy and treatment of cervical intra-epithelial neoplasia are achievable in practice. DESIGN: Identification of 100 consecutive cases of first assessment colposcopy from each gynaecological unit in the former North West region from 1 January 1994 and follow up of their outcome after one year. SETTING: All 19 gynaecological colposcopy clinics in the former North West region. SAMPLE: In one hospital data were available on only 39 women and therefore information was analysed on 1839 women. MAIN OUTCOME MEASURES: Waiting times for colposcopy, different modalities of treatment used for premalignant conditions of the cervix and type of anaesthesia used for treatments. With regard to follow up, time of occurrence, whether or not colposcopy was performed and efficacy of treatment as judged by cervical cytology. RESULTS: Waiting times for colposcopy varied in the individual hospitals studied, but overall 56% of patients were seen within eight weeks. Diathermy loop excision was the most popular treatment modality accounting for 44% of cases. At six months after treatment, 9.98% of patients had a smear of mild dyskaryosis or worse. Colposcopy, as well as cytology, was used at the first follow up visit in 43% of cases. CONCLUSION: At a local level individual hospitals can identify areas where improvements in the service they provide need to be made. The practicality of the current guidelines in today's health service needs questioning.

Emotional reactions in women attending a UK colposcopy clinic.

STUDY OBJECTIVE: To assess the emotional responses of women attending a colposcopy clinic for investigation of an abnormal cervical smear, and to elicit the women's views on the screening service and colposcopy clinic. DESIGN: Over 12 months all new attenders at a colposcopy clinic were invited to join the study. They were assessed psychiatrically four weeks before their first clinic appointment, and four weeks and 32 weeks after their first clinic appointment. SETTING: Colposcopy clinic, John Radcliffe Hospital, Oxford. PATIENTS: Of 114 women attending the colposcopy clinic for investigation of an abnormal cervical smear, 102 agreed to enter the study. MEASUREMENTS: Psychiatric symptoms were assessed with a standardised psychiatric interview, the present state examination; and with four self rated mood scales:--the general health questionnaire, the Beck depression inventory, the Leeds depression scale, and the Leeds anxiety scale. MAIN RESULTS: On all these measures, in the whole patient group, psychiatric morbidity was found to be transient and relatively minor. Thus ratings on the present state examination were not significantly higher than the rate found in a community sample of 520 women in Oxford, while on the four self rated mood scales, mean total scores were lower than the cut off value used to distinguished cases. Patient satisfaction with the colposcopy services was generally high but there was some dissatisfaction with delays. CONCLUSIONS: After an abnormal cervical smear, further investigation by colposcopy is generally associated with low levels of anxiety and depression.

Colposcopy as a primary screening test for cervical cancer.

AIM AND BACKGROUND: To evaluate the cost effectiveness of screening by colposcopy compared to conventional cytology. METHODS: A prospective study was performed in the Florence District screening center on 3,000 consecutive women, self referring, who were examined by cytology and colposcopy in a blind fashion. Further assessment was based on cytologic report or on colposcopy-directed punch biopsy. Actual costs of the whole screening process were known. The cost effectiveness of different possible simulated screening scenarios was then determined. RESULTS: Overall, 18 high-grade lesions (CIN3 = 9, CIN2 = 9) were detected. Four different screening scenarios were compared, namely a) cytology alone, b) cytology + repeat smear for ASCUS (atypical squamous cells of undeterminate significance) cases, c) colposcopy + cytology for cases of condyloma at punch biopsy, and d) colposcopy alone. Although they had a higher cost per examined woman (a) = 17.98, b) = 19.40, c) = 23.86, d) = 22.10 US$), scenarios c) and d) had a higher relative sensitivity (a = 44.4, b = 61.1, c = 100, d = 88.8%) and a lower cost per high-grade lesion detected (a = 6,743, b = 5,291, c = 3,977, d = 4,144 US$). CONCLUSIONS: Screening by colposcopy is a feasible procedure which is more sensitive and more cost effective than conventional cytology screening. At least in those settings where access to cytopathology may be difficult, screening by colposcopy should be considered as a possible alternative.

Variables influencing anxiety of patients with abnormal cervical smears referred for colposcopy.

The state anxiety scores of women with abnormal cervical smears referred for colposcopy were investigated to identify causes of anxiety, factors influencing anxiety and emotions involved with anxiety, in order to define strategies to reduce this anxiety. Forty-seven women were interviewed and completed a questionnaire and the Spielberger State and Trait Anxiety Inventory (STAI): 22 women prior to their intake consultation at the colposcopy clinic of the University Medical Center St Radboud, Nijmegen, and 25 women during their second visit before the actual colposcopy. The mean State anxiety score was 48.2, without significant differences between the intake and colposcopy consultation. The majority experienced anxiety because of a fear of cancer and/or the colposcopy. The mean State anxiety score was significantly higher in women who considered the level of information provided by the gynecologist/family practitioner insufficient, who experienced a long waiting time, who did not have a partner, and who experienced additional emotions like anger and sadness. In conclusion, patients referred for colposcopy after an abnormal cervical smear result have high levels of anxiety. High levels of anxiety may be reduced by uniform and explicit information about cervical smear results and colposcopy, by reduction of clinic waiting times, by stimulating social support, and by attention to emotions like anger and sadness.

Using history and colposcopy to select women for endocervical curettage. Results from 2,287 cases.

OBJECTIVE: To enhance the yield of endocervical curettage (ECC) by defining risks for abnormality. STUDY DESIGN: Demographic and medical information collected at colposcopy and subsequent histology were reviewed retrospectively. Statistical analysis was by t and chi 2 tests. RESULTS: Among 2,287 women undergoing ECC at colposcopy, in only 105 (5%) did positive ECC require excisional therapy that would not otherwise have been recommended. Women with positive ECC were older (mean, 39.0 vs. 33.2 years; P < .001) and of higher parity (mean, 3.0 vs. 2.0 births; P < .001), with earlier first intercourse (at 16.6 vs. 17.2 years, P = .006), more unsatisfactory colposcopy (148 [27%] of 545 women with unsatisfactory colposcopy vs. 183 [12%] of 1,523 women with satisfactory colposcopy; P < .001) and more colposcopic impressions of cervical intraepithelial neoplasia (CIN) 2-3 (163 [51%] of 323 vs. 443 [25.6%] of 1,730 women with low grade or a negative impression; P < .001). The likelihood of missed CIN 2-3 was 0.4%, with no missed cancers among women with satisfactory colposcopy and either a normal colposcopic impression (1/254) or nulliparity (2/474). CONCLUSION: ECC identifies otherwise-undetected preinvasive and invasive lesions but may be avoided in women with satisfactory colposcopy who are nulliparous or have no colposcopic lesions.

[Role of colposcopy in the diagnosis of human papillomavirus infection of the uterine cervix].

Among 6706 women screened by cytology, only 9 (0.13%) showed evidence of human papillomavirus infection (HPVI). In 133 women examined by colposcopy for abnormal cytology or/and suspected lesions on the cervix, 41 (30.8%) showed subclinical papillomavirus infection (SPI) while 17.4% and 5.3% showed HPVI by histopathology and cytology, respectively. The conformation rate between colposcopy and pathology was 69.6%. Sixty-nine specimens out of 133 colposcopy guided biopsies were assayed by HPV-DNA dot hybridization with 6B/11, 16, 18 probes to detect the presence of HPV-DNA in the cervical specimens. Thirty-nine (56.5%) gave a positive result. The colposcopic predictive value of positive result for HPVI was 76.7%. The difference between colposcopy (59%) and pathology (20.5%) is statistically significant (P less than 0.01). These results suggest that colposcopy is superior to cytology and histopathology for the detection of SPI in the cervix. In colposcopy HPV-DNA positive women, aceto-while-epithelium was most common (28.2%). As it is difficult to differentiate SPI from cervical intraepithelial neoplasia especially the Grade I lesion by colposcopy, discrimination criteria are proposed together with the chief colposcopic features of SPI.

Human papillomavirus (HPV) testing in the management of women with abnormal Pap smears. Experience of a colposcopy referral clinic.

BACKGROUND AND OBJECTIVES: Several detailed algorithms for the appropriate use of human papillomavirus (HPV) testing in the management of women with abnormal Pap (Papanicolaou) smears have been launched, but their direct country-to-country adoption is difficult. This necessitates their testing in individual settings, which is ongoing in our colposcopy referral clinic. METHODS: A series of 224 consecutive women attending the clinic with the usual referral indications (ASC-US or higher in Pap) were examined by the conventional diagnostic tools (PAP smear, colposcopy, punch biopsy) and subjected to HPV testing and viral typing for both low-risk (L-R) and high-risk (H-R) types by nested PCR-based techniques. Predictors of the high-grade diagnostic categories were analysed using both univariate- and multivariate modelling, and the performance characteristics (sensitivity, specificity, NPV, PPV) of all tests in detecting high-grade CIN were calculated. RESULTS: In the PAP test, ASC-US smears were most common (37.9%), followed by low-grade squamous intraepithelial lesions (LSIL) (26.3%) and high-grade SIL (HSIL) (4.9%). Colposcopy was performed for 180 women, of whom 48.3% had a normal transformation zone (TZ), 40.6% had ATZ1 (abnormal TZ grade 1), and 5.6% had ATZ2. In biopsy (n = 71), 49.3% had CIN1, 5.6% CIN2, and 16.9% CIN3. The HPV test was positive in 64 (28.8%) women, more often in those aged < 35 years (p = 0.025). High-grade colposcopy (ATZ2) was significantly associated with HSIL in the Pap test (OR 20.5; 95% CI: 4.34-96.47), and with HPV test positivity (OR 6.37; 95% CI: 1.58-25.73). The most significant predictors of CIN3 were HSIL in the PAP, HPV test positivity, and high-grade colposcopy. HSIL and HPV test (for H-R types), but not colposcopy, retained their significance as independent predictors of CIN3 also in adjusted multivariate models: OR 88.27; 95% CI 4.17-1867.04, and OR 19.46; 95% CI 2.01-187.75, for the HSIL and H-R HPV test, respectively. Changing the cut-off level of the Pap test from ASC-US to HSIL increased the specificity of the test up to 96.4%, with the loss in sensitivity from 87.5% to 43.8%. Colposcopy (ATZ2) had 92% specificity, and NPV competing with that of the Pap test. The sensitivity of HPV test exceeds that of the Pap test at HSIL cut-off level, but the specificity of the PAP test is clearly superior. CONCLUSIONS: Accurate predictors of significant cervical pathology (CIN3) are well defined, but the problem is the different performance of the diagnostic tools in clinical practice. A proficient combination of the tests is likely to result in the most satisfactory clinical practice in the management of women with abnormal Pap tests (MAPS).

Family physicians' colposcopy practices.

BACKGROUND: The objectives of this study were to determine (1) the extent to which family physicians are performing colposcopy, (2) which colposcopic procedures are performed by these family physicians, (3) demographic characteristics of physicians who perform colposcopy, and (4) whether physicians who do not perform colposcopy plan to do so in the future. METHODS: A questionnaire was mailed to all 757 self-identified family practice physicians in Arizona. RESULTS: The return rate was 72 percent, and the response rate was 55.5 percent. Results indicated that 19.3 percent of respondents were trained to perform colposcopy, and 9.5 percent actually have performed it. For those performing colposcopy, the mean number of procedures performed during the previous 6 months was 25 (range 2-100). CONCLUSIONS: Certain barriers to performing colposcopy were identified: (1) lack of available training, (2) interspecialty "turf battles," (3) quality assurance, and (4) the cost of malpractice liability insurance. Nevertheless, there were no insurmountable reasons why family physicians could not perform colposcopy.

Necessity for endocervical curettage in elderly women undergoing colposcopy.

A retrospective study of 164 women aged 45 and older undergoing colposcopy for abnormal Papanicolaou smears showed that 49% had adequate colposcopy and 51%, inadequate colposcopy. Of those with adequate colposcopy, 23% had positive endocervical curettage (ECC). That finding required conization, which detected one case of microinvasive and two of invasive cervical carcinoma. Of those with inadequate colposcopy, 64% had positive ECC. All patients with inadequate colposcopy underwent conization, which detected 4 cases of microinvasive and 11 of invasive carcinoma. Therefore, women with inadequate colposcopy had a higher risk of invasive disease. ECC is a necessary step in the colposcopic evaluation of elderly women.

Influences on teaching colposcopy and treatment modalities in family practice programs.

BACKGROUND: Colposcopy and related therapeutic modalities are taught in many family practice residency programs. The role of the following two factors in a family practice residency program's decision to teach these procedures was evaluated: 1) the coexistence of an obstetrics and gynecology (OB-GYN) residency program at the affiliated hospital and 2) the perceived attitude of community obstetrician-gynecologists toward family physicians performing the procedures. METHODS: In 1993, all 399 accredited family practice residency programs were surveyed, with a response rate of 86.5%. RESULTS: Ninety-three percent of responding programs taught colposcopy. All programs that rated community obstetrician-gynecologists' attitudes as positive taught colposcopy, and 91% taught cryotherapy. In programs rating local obstetrician-gynecologists' attitudes as negative, 85.5% taught colposcopy, and 71% taught cryotherapy. A co-located OB-GYN program did not influence a family practice program's likelihood of teaching colposcopy or treatment modalities. CONCLUSION: A perception that community obstetrician-gynecologists have negative attitudes about family physicians performing colposcopy may dissuade some family practice programs from teaching colposcopy and related treatment modalities. This influence was not seen in programs with a co-located OB-GYN residency.

Use of speculoscopy in the evaluation of women with atypical Papanicolaou smears. Improved cost effectiveness by selective colposcopy.

Since up to 45% of patients with atypical Papanicolaou smears have been shown to have significant pathology, women with persistent atypia are usually referred for colposcopy. This study evaluated the use of a new adjunctive screening test, speculoscopy, in selecting women with atypical Papanicolaou smears who would most benefit from referral for colposcopy. Both screening and referral patients were evaluated with the Papanicolaou smear, speculoscopy and colposcopy at 10 study centers. Biopsies were obtained from most women with positive colposcopy. The results in patients with atypical smears were used to perform a cost-benefit analysis of each of three management protocols. Using the results of speculoscopy to select women with atypical Papanicolaou smears for colposcopy provided a cost-effective alternative to performing colposcopy either on all women or on those with persistent atypia following treatment. Even when all women undergo speculoscopy at the time of screening, this protocol provides a cost savings of up to 24% and no significant loss of diagnostic accuracy. These data suggest that speculoscopy performed at the time of initial screening can accurately select women with atypical Papanicolaou smears who require colposcopy for diagnostic biopsy in a cost-effective manner.

Knowledge of cervical cancer screening among women attending urban colposcopy clinics.

To determine knowledge about cervical cancer screening among women referred to urban colposcopy clinics and to assess effects of colposcopy and directed teaching on knowledge deficits, a closed-ended questionnaire was distributed to 144 women at a university resident clinic before and after initial colposcopy. Results were compared with those of 42 patients attending a health maintenance organization (HMO) for the same procedure. Fewer than half of clinic patients correctly identified the nature of a Pap smear or the reason for their referral, but 84% knew that Pap smears were indicated annually. Fewer than 60% knew the nature of colposcopy or the organ that it evaluated, but 74% could identify its indication. Clinic patients' knowledge of colposcopy but not of Pap smears improved after colposcopy and teaching. While HMO patients had better overall understanding of Pap smears and colposcopy, a multivariate analysis found educational level to be the only significant predictor of this knowledge. Efforts to boost cervical cancer screening through improved understanding should be directed toward women with the least schooling without regard to other demographic factors.

On-site colposcopy services in a family practice residency clinic: impact on physician test-ordering behavior, patient compliance, and practice revenue generation.

BACKGROUND: Using colposcopy as a model, we examined the impact of introducing a new diagnostic technology into the ambulatory primary care setting. METHODS: Records of patients with abnormal findings on Papanicolaou smears were reviewed from three study periods: 1 year before, 1 year after, and 5 years after initiation of on-site colposcopy services. Data analyzed include physician management decisions, site of colposcopic service, and patient compliance. Practice revenue estimates were based upon patterns of physician management and patient compliance found during each study period. RESULTS: Management of low-grade squamous intraepithelial lesions varied during each study period. By period 3, however, most patients were undergoing colposcopy (P = 0.03). High-grade squamous intraepithelial lesions were uniformly managed with colposcopy during all study periods (P < 0.001). Introduction of on-site colposcopic services resulted in a rapid shift to the on-site location for evaluation of low-grade squamous intraepithelial lesions and a more gradual shift to the on-site location for evaluation of high-grade squamous intraepithelial lesions. Patient compliance was not affected by the introduction of on-site services. On-site colposcopy resulted in a nearly 100 percent transfer of revenue to the practice, but the economic benefit was quite modest. CONCLUSIONS: Although offering on-site colposcopy services might have had some impact on physician management of low-grade squamous intraepithelial lesions, the lack of benefit regarding patient compliance, the relatively small patient volume for this procedure, and its modest impact on practice revenue cause us to question the value of including colposcopy in everyday practice.
