Abstract
Approximately 500,000 women are diagnosed with cervical cancer annually, with high-grade cervical intraepithelial neoplasia (CIN) estimated to be 20 times higher. The diathermy ablation is an inexpensive minimally invasive surgeries for CIN. However, little is known about the treatment outcomes. A prospective clinical trial was therefore conducted to evaluate ablation outcomes based on detailed colposcopy findings, cytology, and biopsy results over a two-year period. We enrolled CIN2 (n = 32) and CIN3 (n = 7) patients. Eligibility criteria included: aged between 29 and 49 (median: 36, mean: 36.3), visible transformation zone with high-grade lesions not entirely occupying the cervix, and histologically diagnosed with CIN2 or CIN3. Cytology and HPV genotyping were performed, and colposcopic findings were evaluated. Colposcopy-guided diathermy ablation was conducted by a certified gynecologic oncologist. The incidence of recurrent or residual disease was 5.1% (2/39, 95% confidence interval: - 0.02 to 0.12). The prevalence of HPV infection at 12 months decreased after surgery, as 67.6% (23/34, 0.52-0.83) of patients were HPV-negative. No severe adverse events were reported, while there were five pregnancies with full-term deliveries. The promising outcome was possibly due to selection of rigorous surgical indication and skilled surgical techniques. The study highlights the importance of experienced and skilled colposcopists.TrialRegistry This study was registered in the clinical trial registration system of the University hospital Medical Information Network Clinical Trials Registry (UMIN-CTR ID: UMIN000024483). Open for the trial to the public through the website: 01/11/2016. First registration of the patient: 30/01/2017.

Abstract
In 2020, the World Health Organization (WHO) launched a strategy to eliminate cervical cancer as a public health problem. To support the strategy, the WHO published updated cervical screening guidelines in 2021. To inform this update, we used an established modeling platform, Policy1-Cervix, to evaluate the impact of seven primary screening scenarios across 78 low- and lower-middle-income countries (LMICs) for the general population of women. Assuming 70% coverage, we found that primary human papillomavirus (HPV) screening approaches were the most effective and cost-effective, reducing cervical cancer age-standardized mortality rates by 63-67% when offered every 5 years. Strategies involving triaging women before treatment (with 16/18 genotyping, cytology, visual inspection with acetic acid (VIA) or colposcopy) had close-to-similar effectiveness to HPV screening without triage and fewer pre-cancer treatments. Screening with VIA or cytology every 3 years was less effective and less cost-effective than HPV screening every 5 years. Furthermore, VIA generated more than double the number of pre-cancer treatments compared to HPV. In conclusion, primary HPV screening is the most effective, cost-effective and efficient cervical screening option in LMICs. These findings have directly informed WHO's updated cervical screening guidelines for the general population of women, which recommend primary HPV screening in a screen-and-treat or screen-triage-and-treat approach, starting from age 30 years with screening every 5 years or 10 years.

Abstract
OBJECTIVE Although value-based healthcare (VBHC) views accurate cost information to be crucial in the pursuit of value, little is known about how the costs of care should be measured. The aim of this review is to identify how costs are currently measured in VBHC, and which cost measurement methods can facilitate VBHC or value-based decision making. DESIGN Two reviewers systematically search the PubMed/MEDLINE, Embase, EBSCOhost and Web of Science databases for publications up to 1 January 2022 and follow Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify relevant studies for further analysis. ELIGIBILITY CRITERIA Studies should measure the costs of an intervention, treatment or care path and label the study as 'value based'. An inductive qualitative approach was used to identify studies that adopted management accounting techniques to identify if or how cost information facilitated VBHC by aiding decision-making. RESULTS We identified 1930 studies, of which 215 measured costs in a VBHC setting. Half of these studies measured hospital costs (110, 51.2%) and the rest relied on reimbursement amounts. Sophisticated costing methods that allocate both direct and indirect costs to care paths were seen as able to provide valuable managerial information by facilitating care path adjustments (39), benchmarking (38), the identification of cost drivers (47) and the measurement of total costs or cost savings (26). We found three best practices that were key to success in cost measurement: process mapping (33), expert input (17) and observations (24). CONCLUSIONS Cost information can facilitate VBHC. Time-driven activity-based costing (TDABC) is viewed as the best method although its ability to inform decision-making depends on how it is implemented. While costing short, or partial, care paths and surgical episodes produces accurate cost information, it provides only limited decision-making information. Practitioners are advised to focus on costing full care cycles and to consider both direct and indirect costs through TDABC.

Abstract
BACKGROUND Loop electrosurgical excision procedure (LEEP) for high-grade squamous intraepithelial lesion is performed in both an inpatient setting under general anaesthesia and an outpatient setting under local anaesthesia. Efficacy and safety are comparable and outpatient LEEP may save time and cost in the Australian setting. AIMS We aim to compare patient satisfaction with inpatient LEEP compared to outpatient LEEP for Australian best practice. MATERIALS AND METHODS This was a prospective quantitative and qualitative cohort study. An online questionnaire was sent to patients undergoing inpatient and outpatient LEEP to assess satisfaction with the procedure. Further histopathological and demographic data were also collected from the medical records. Groups were compared using Fischer's exact test and pain scores were compared using non-parametric tests. RESULTS Ninety-three outpatients and 52 inpatients responded to the survey. No difference was found between groups with regard to rate of positive histopathological margins or number of passes required. Outpatients found the procedure to be more convenient than inpatients (P = 0.007), and experienced more pain during the procedure than the inpatient group (P < 0.001). There was no significant difference in pain scores following the procedure or post-procedure anxiety. CONCLUSIONS Outpatient LEEP is an acceptable and well-tolerated procedure, comparable to inpatient LEEP. Regardless of the option chosen, patients are highly likely to be satisfied with their choice. Increased efforts should be made to reduce pre-procedural anxiety, which may in turn reduce expectations and experiences of pain.

Abstract
Purpose: To investigate the long-term psychosexual outcomes in women following excisional cervical treatment. Materials and methods: Women with cold-knife conization (CKC) or large loop excision of the transformation zone (LLETZ) treatment were interviewed after a follow-up colposcopy visit. Their demographics, treatment and psychosexual characteristics were recorded. Results: One hundred and forty six women with a mean age of 35.2 ± 5.4 years underwent either LLETZ (68.5%) or CKC (31.5%) treatment within 4.7 ± 2.7 years (range: 2-15) before the interview. 27.4% of women were less interested in sexual intercourse following treatment in comparison with their interest before. Those women with less interest in sexual intercourse after treatment had higher anxiety and depression scores and were more worried about disease progression. Women with post-treatment complications were at risk of less interest in sexual intercourse and of greater anxiety and depression. Women with abnormal smears at follow-up were at risk of greater anxiety. The type of treatment and grade of dysplasia did not affect their interest in sexual intercourse or the anxiety and depression scores. Conclusions: Approximately, one-third of women at more than two years post-treatment may suffer from less interest in sexual intercourse, have relatively greater anxiety and depression, and might still be concerned about the possibility of disease progression.

Abstract
BACKGROUND Although colposcopy is the leading follow-up option for women with abnormal cervical cytology, little is known about its psychological consequences. OBJECTIVES We performed a systematic review to examine: (1) what, if any, are the adverse psychological outcomes following colposcopy and related procedures; (2) what are the predictors of adverse psychological outcomes post-colposcopy; and (3) what happens to these outcomes over time. SEARCH STRATEGY Five electronic databases (PubMed, PsychINFO, CINAHL, Web of Science, Scopus) were searched for studies published in English between January 1986 and February 2014. SELECTION CRITERIA Eligible studies assessed psychological wellbeing at one or more time-points post-colposcopy. DATA COLLECTION AND ANALYSIS Two reviewers independently screened titles and abstracts. Full texts of potentially eligible papers were reviewed. Data were abstracted from, and a quality appraisal performed of, eligible papers. MAIN RESULTS Twenty-three papers reporting 16 studies were eligible. Colposcopy and related procedures can lead to adverse psychological outcomes, particularly anxiety. Ten studies investigated predictors of adverse psychological outcomes; management type and treatment had no impact on this. Seven studies investigated temporal trends in psychological outcomes post-colposcopy; findings were mixed, especially in relation to anxiety and distress. Studies were methodologically heterogeneous. CONCLUSIONS Follow-up investigations and procedures for abnormal cervical cytology can cause adverse psychological outcomes among women. However, little is known about the predictors of these outcomes or how long they persist. There is a need for a more standardised approach to the examination of the psychological impact of colposcopy, especially longer-term outcomes. TWEETABLE ABSTRACT Follow-up investigations for abnormal cervical cytology can cause adverse psychological outcome among women.

Abstract
OBJECTIVE To evaluate the reliability of endocervical curettage (ECC) in patients previously treated for CIN. PATIENTS AND METHODS Retrospective analysis of data from 85 patients between January 1985 and December 2011 who received an ECC during monitoring after treatment of CIN. The reliability of the ECC was evaluated by comparison with the final histological analysis of the surgical specimen or the data for subsequent cyto-colpo-histological follow-up. RESULTS Patients were referred to colposcopy either within the immediate post-treatment monitoring (n=42), meanly 9.7±5.3 months after treatment, or if cytological abnormalities were detected during long-term monitoring, meanly 78.6±52.4 months after treatment. Colposcopy was unsatisfactory in 75.3% of patients and normal colposcopic findings were found in 80% of patients. A perfect agreement between the ECC and the endocervical final diagnosis was noted in 68 patients (80%). For the diagnosis of severe cervical lesions (CIN 2+) ECC had a sensitivity of 86.2% (68.3-96.1), a specificity of 94.6% (85.1-98.9) and positive and negative predictive values of 61.4% (47.6-74.0) and 93% (83.0-98.1), respectively. CONCLUSION The high sensitivity and negative predictive value of ECC for the diagnosis of severe post-therapeutic endocervical lesions avoid iterative treatment without increasing the risk of progression of a lesion to cancer.

Abstract
PURPOSE The aim of our study was to evaluate the risk factors for treatment failure of CO2 laser vaporization in patients with cervical intraepithelial neoplasia 2 (CIN2). METHODS Medical records of patients who received either shallow or deep CO2 laser vaporization with biopsy-proven CIN2 during March 2007 to April 2011 were reviewed retrospectively. After laser vaporization, liquid-based cytology and human papilloma virus (HPV) DNA testing were checked in every follow-up visit. Treatment failure was defined when the follow-up biopsy was more than CIN2, needing secondary surgical treatment. RESULTS During that period, 141 patients with CIN2 underwent CO2 laser vaporization. After laser ablation, 14 of 141 women needed the secondary treatment, a success rate of laser vaporization of 90.1 %. In multivariate analysis, the previous loop electrosurgical excision procedure (LEEP) history (adjusted OR = 13.649; P value = 0.025) and the ablation depth (adjusted OR = 11.279; P value = 0.006) were independent factors associated with treatment failure. CONCLUSION Both ablation depth and previous LEEP history were the important factors increasing the risk for the treatment failure of CO2 laser vaporization in CIN2.
