BACKGROUND: Although the incidence of precancerous conditions of the cervix has recently been increasing, prompt initial and long-term follow-up care can effectively reduce unnecessary morbidity and mortality. For example, the 4-year survival rates among those individuals at greatest risk for cervical cancer (i.e., minority women of low socioeconomic status) approach 95% with early detection. Women who present with advanced disease have a much poorer outlook (0%-39% survival). Yet, high-risk individuals are least likely to adhere to recommended diagnostic regimens. PURPOSE: We tested the effectiveness of a brief telephone counseling intervention directed to low-income, inner-city women after they had received an abnormal Pap smear result. The women were counseled on the importance of having an initial and 6-month repeat follow-up diagnostic procedure (i.e., colposcopic examination of the cervix). METHODS: A randomized trial design was used to compare the effects on these women of telephone counseling with (n = 192) or without (n = 203) a booster counseling telephone call prior to the appointment for a repeat colposcopy 6 months later, with a telephone appointment confirmation/reminder call (n = 216) and with standard care (i.e., no telephone contact) (n = 217). The telephone counseling protocol probed for and addressed three psychologic barriers to adherence (i.e., attendance at appointment for colposcopy examination): 1) encoding/expectancy (e.g., did the patient understand her risk of developing cervical cancer?); 2) affective/emotional (e.g., was the woman worried about the condition and its consequences?); and 3) self-regulatory/practical (e.g., was the woman likely to forget medical appointments?). Logistic regression was used to analyze the effects of the intervention group and the type of psychologic barriers elicited on colposcopy adherence. RESULTS: The results of logistic regression analysis (using those who received an appointment confirmation/reminder telephone call as the comparison group) revealed that telephone counseling produced significantly higher adherence rates to the initial colposcopy visit compared with telephone confirmation (300 [76%] of 395 women versus 147 [68%] of 216; odds ratio [OR] = 1.50; 95% confidence interval [CI] = 1.04-2.17). Additionally, standard care resulted in significantly lower adherence rates than did telephone confirmation (109 [50%] of 217 women versus 147 [68%] of 216; OR = 0.47; 95% CI = 0.32-0.73). Regarding attendance at the 6-month repeat colposcopy appointments, the 80 patients who had received telephone counseling prior to the initial visit (and were recommended for follow-up colposcopy) were significantly more likely to adhere than were the 47 patients who had received telephone confirmation (49 [61%] of 80 women versus 17 [36.2%] of 47; OR = 2.70; 95% CI = 1.15-6.51). The 6-month adherence rates for patients in the telephone confirmation group and the standard care group (n = 30) were low and did not differ significantly (17 [36.2%] of 47 women versus nine [30.0%] of 30; OR = 1.08; 95% CI = 0.40-2.89). Forgetting medical appointments (OR = 0.31; 95% CI = 0.19-0.51) and having scheduling conflicts (OR = 0.45; 95% CI = 0.28-0.72) were also associated with lower rates of adherence. CONCLUSION: The use of telephone counseling appears to be an effective strategy for enhancing initial and long-term adherence to a follow-up cervical diagnostic procedure in a traditionally underserved population. Patients who respond to a positive Pap test result with a particular profile of psychologic barriers may require more intensive and targeted counseling interventions.
OBJECTIVE: To determine the possible role of the selective 'see and loop' approach with a loop electrosurgical excision procedure (LEEP) for high grade cervical intra-epithelial neoplasia (CIN). DESIGN: Comparison of the colposcopic and histological diagnosis in patients who received LEEP treatment. SUBJECTS: Subjects included 95 patients from May to October 1994. SETTING: Department of Obstetrics and Gynaecology, the Prince of Wales Hospital, the Chinese University of Hong Kong. MAIN OUTCOME MEASURES: Agreement between colposcopic and histological diagnosis and between histological diagnosis by biopsy and by LEEP. Sensitivity and false positive rate of colposcopic diagnosis in different classifications of high grade CIN lesions. Decision analysis on the cost of three proposed strategies based on the study results. RESULTS: The colposcopic diagnosis was correct in 58% of cases with 31% overall and 11% undercall rates. The false positive rate of colposcopic examination was 11.4% in the diagnosis of CIN III or more advanced lesions and 36.8% if CIN II lesions are also classified as high grade. Decision analysis showed a saving of: (i) US$53,000: or (ii) US$73,000 per annum if 'see and loop' was performed on all cases where colposcopic diagnosis is: (i) CIN III or more; or (ii) CIN II or more. If the cost of inappropriate surgery by LEEP is estimated to be more than US$550 per person over-treated (i) becomes the preferred strategy. CONCLUSIONS: Selective 'see and loop' approach for high grade CIN III lesions suspected on colposcopy will not over-treat significantly but will reduce the number of colposcopy appointments, waiting list for colposcopy and subsequent expenses.
OBJECTIVE: To assess the diagnostic accuracy of a new technique of cervical imaging and to consider its potential as a secondary cervical screening method. DESIGN: A prospective cross-sectional study with each case acting as its own control, comparing video colpography with colposcopy. SETTING: University of Birmingham colposcopy clinics, City Hospital and Birmingham Women's Hospital. PARTICIPANTS: Fifty women referred for colposcopy. INTERVENTIONS: The women had a video colpogram recording made prior to colposcopy. MAIN OUTCOME MEASURES: The proportion of technically suitable colpograms obtained and the level of agreement between colposcopist and video screener. RESULTS: The images were satisfactory or good in 94% cases, and there was a very high level of agreement between colposcopist and video screener (kappa = 0.79). If the technique had been used in a primary health care setting as a secondary screening method for women with low grade cervical smear abnormalities, 61% would have avoided referral for colposcopy. CONCLUSIONS: Video colpography is an accurate, portable and quick method of cervical imaging. It combines the simplicity of a video camera with the versatility of computerised digital imaging and has great potential in the fields of teaching, audit and screening of low grade smear abnormalities.
