A Qualitative Exploration of Barriers to Treatment Among HPV-Positive Women in a Cervical Cancer Screening Study in Western Kenya

"The problem is not detection, it is treatment": exploring why women needing pre-cervical cancer care are lost to follow-up at the hospital in Iquitos, Peru

BACKGROUND

The objective of this study was to explore the barriers to follow-up - as well as potential ways to reduce these - of women with cervical lesions suspicious for cancer who were ineligible for primary-level treatment and needed, but did not receive, hospital-level follow-up in Iquitos, Peru.

METHODS

In-depth, semi-structured interviews were conducted with 18 HPV-positive women requiring hospital-level follow-up but for whom there was no documentation of completion regarding their experienced barriers to follow-up and suggestions to reduce these barriers. After thematically analyzing these patient interviews, interview findings about these topics were presented to seven doctors and five nurse-midwives at both the hospital and primary care levels. Finally, 19 health authorities and professionals discussed all findings and identified action steps for systems-level changes at a group model building workshop.

RESULTS

Patient-identified barriers to hospital care were mainly: (1) a limited patient understanding of follow-up or treatment steps (both prior to and after the hospital visit), and (2) administrative challenges to obtaining appointments or follow-up care at the hospital. Patients identified the utility of a patient navigator for this process to reduce these barriers. The healthcare professionals concurred with the barriers identified by the patients and the suggestion of a patient navigator, but further elucidated suggestions for change, including (1) differentiating referral for those with suspicion for cancer to prioritize those patients when referred to the hospital, (2) increasing information flow between the different levels of care through an integrated patient registry, and (3) improving provider education regarding HPV and the standard of care. The group model building workshop served as a space to discuss findings and action items that could potentially make these changes possible to ultimately improve the continuum of care.

CONCLUSIONS

Despite an overall increase in follow-up for HPV-positive women since the implementation of the new HPV-based screen-and-treat program, women suspicious for cervical cancer are still being lost to follow-up after being referred to the hospital. Systems-level improvements should focus on improving information about patient flow across the continuum of care for health providers and hospital staff (who make appointments), strengthening referral systems between primary and tertiary level providers through an integrated patient registry, improving health education on HPV and screening for patients, and establishing a patient navigation system.

LP. A prospective model of the potential clinical and economic impact of cervical cancer screening supported by a mobile phone app

INTRODUCTION

Cervical cancer is a preventable and highly curable disease when detected early and adequately treated, yet it remains the leading cause of cancer-related death in women in Kenya due to low screening coverage and treatment. Implementing World Health Organization screening guidelines for human papillomavirus (HPV) is challenging due to the complex logistics of result return and follow-up requiring multiple clinic visits. Increasing the use of mobile technology can support follow-up care in cervical cancer screening programs.

METHODS

We developed a prospective clinico-economic model to assess the potential impact of a mobile phone-based application ("app") communicating laboratory results and recommendations to improve follow-up care for cervical cancer screening in Kenya. The model is structured to simulate a three-visit pathway for HPV-based screening used in a clinical trial of the app and based on epidemiological data, clinical guideline-based workflow, and patient-based behavioral pathways. Published literature, expert elicitation, and time-and-motion observations were used to estimate clinical data, care pathways, and visit-related costs. This analysis was conducted from a base-case healthcare system perspective with a scenario from a "limited" societal perspective.

RESULTS

In a simulated cohort of women using the app-based intervention compared to conventional care, with 10,000 women in each arm, use of the app is projected to increase healthcare costs by $12.53 per enrolled woman during the trial period and to detect and treat an additional 247 women-229 with precancerous cervical lesions and 18 with cervical cancer. The incremental cost-effectiveness ratio of the app versus conventional care was $174 per case detected and treated. This would be cost-saving given the average lifetime cost per cervical cancer case of $1,000-$3,000.

CONCLUSION

Use of a mobile phone-based app is costlier than conventional screening but by improving visit compliance, it can be a cost-effective and cost-saving strategy to enhance detection and treatment in cervical cancer screening programs.

"The problem is not detection, it is treatment": Exploring Why Women Needing Pre-Cervical Cancer Care are Lost to Follow-Up at the Hospital in Iquitos, Peru

Background

The objective of this study was to investigate the barriers to follow-up of women with cervical lesions suspicious of cancer who were ineligible for primary-level treatment and needed, but did not receive, hospital-level care in Loreto, Peru.

Methods

In-depth, semi-structured interviews were conducted with 18 HPV-positive women requiring hospital-level follow-up care for cervical lesions suspicious of cancer but for whom there was no documentation of completion of treatment. After thematically analyzing these patient interviews, interview findings were presented to seven doctors and five nurse-midwives at both the hospital and the primary levels for comments and suggestions regarding barriers to treatment. Finally, all findings were presented at a group model building workshop with 19 health authorities and professionals, where action items were discussed to elicit suggestions for systems-level changes.

Results

Interviewed patients and healthcare professionals expressed the need to improve communication between levels of care, as well as the need to implement a patient navigation program. Interviewees also discussed the barriers patients encountered in obtaining hospital-level follow-up that ultimately affected their continuum of care. Patient-identified barriers to hospital care were grouped into three main themes: (1) limited patient understanding of treatment steps, (2) the need for multiple trips to the hospital to obtain care, and (3) lack of provider follow-up, leading to their suggestion for (4) the need for patient navigators. The healthcare professionals concurred with the barriers identified by the patients, but further elucidated suggestions for change such as (1) prioritizing patients with a high risk of cancer when referring to the hospital, and (2) increasing communication between the different levels of care. The group model building workshop served as a space to discuss findings and action items that could potentially make these changes possible.

Conclusions

Despite an overall increase in follow-up for HPV-positive women since the implementation of the new HPV-based screen-and-treat program, women at high risk of developing cervical cancer are still being lost to follow-up after being referred to the hospital for care. The challenges faced by both providers and patients are complex and require systems-level improvements.

Electronic Health Interventions and Cervical Cancer Screening: Systematic Review and Meta-Analysis

BACKGROUND

Cervical cancer is a significant cause of mortality in women. Although screening has reduced cervical cancer mortality, screening rates remain suboptimal. Electronic health interventions emerge as promising strategies to effectively tackle this issue.

OBJECTIVE

This systematic review and meta-analysis aimed to determine the effectiveness of electronic health interventions in cervical cancer screening.

METHODS

On December 29, 2023, we performed an extensive search for randomized controlled trials evaluating electronic health interventions to promote cervical cancer screening in adults. The search covered multiple databases, including MEDLINE, the Cochrane Central Registry of Controlled Trials, Embase, PsycINFO, PubMed, Scopus, Web of Science, and the Cumulative Index to Nursing and Allied Health Literature. These studies examined the effectiveness of electronic health interventions on cervical cancer screening. Studies published between 2013 and 2022 were included. Two independent reviewers evaluated the titles, abstracts, and full-text publications, also assessing the risk of bias using the Cochrane Risk of Bias 2 tool. Subgroup analysis was conducted based on subjects, intervention type, and economic level. The Mantel-Haenszel method was used within a random-effects model to pool the relative risk of participation in cervical cancer screening.

RESULTS

A screening of 713 records identified 14 articles (15 studies) with 23,102 participants, which were included in the final analysis. The intervention strategies used in these studies included short messaging services (4/14), multimode interventions (4/14), phone calls (2/14), web videos (3/14), and internet-based booking (1/14). The results indicated that electronic health interventions were more effective than control interventions for improving cervical cancer screening rates (relative risk [RR] 1.464, 95% CI 1.285-1.667; P<.001; I2=84%), cervical cancer screening (intention-to-treat) (RR 1.382, 95% CI 1.214-1.574; P<.001; I2=82%), and cervical cancer screening (per-protocol; RR 1.565, 95% CI 1.381-1.772; P<.001; I2=74%). Subgroup analysis revealed that phone calls (RR 1.82, 95% CI 1.40-2.38), multimode (RR 1.62, 95% CI 1.26-2.08), SMS (RR 1.41, 95% CI 1.14-1.73), and video- and internet-based booking (RR 1.25, 95% CI 1.03-1.51) interventions were superior to usual care. In addition, electronic health interventions did not show a statistically significant improvement in cervical cancer screening rates among women with HPV (RR 1.17, 95% CI 0.95-1.45). Electronic health interventions had a greater impact on improving cervical cancer screening rates among women in low- and middle-income areas (RR 1.51, 95% CI 1.27-1.79). There were no indications of small study effects or publication bias.

CONCLUSIONS

Electronic health interventions are recommended in cervical cancer screening programs due to their potential to increase participation rates. However, significant heterogeneity remained in this meta-analysis. Researchers should conduct large-scale studies focusing on the cost-effectiveness of these interventions.

Challenges associated with follow-up care after implementation of an HPV screen-and-treat program with ablative therapy for cervical cancer prevention

BACKGROUND

Cervical cancer is a preventable cancer; however, decreasing its prevalence requires early detection and treatment strategies that reduce rates of loss to follow-up. This study explores factors associated with loss to follow-up among HPV-positive women after implementation of a new HPV-based screen-and-treat approach for cervical cancer prevention in Iquitos, Peru.

METHODS

We conducted semi-structured interviews with "obstetras" (i.e., midwives) (n = 15) working in cervical cancer prevention and women (n = 24) who were recorded as lost to follow-up after positive HPV results. We used the Health Care Access Barriers Model to guide analyses. We utilized manifest content analysis to describe barriers to follow-up according to the obstetras and thematic analysis to report themes from the women's perspectives. We also report the steps and time taken to contact women.

RESULTS

We found an incomplete and fragmented patient monitoring system. This incomplete system, in conjunction with challenges in contacting some of the women, led to structural barriers for the obstetras when attempting to deliver positive results. Women in this study expressed a desire to receive treatment, however, faced cognitive barriers including a lack of understanding about HPV results and treatment procedures, fear or anxiety about HPV or treatment, and confusion about the follow-up process. Women also reported having important work matters as a barrier and reported frequently using natural medicine. Reported financial barriers were minimal.

CONCLUSION

This study highlights the barriers to follow-up after implementation of a primary-level HPV-based screen-and-treat approach. While some barriers that have previously been associated with loss to follow-up were not as prominently observed in this study (e.g., financial), we emphasize the need for screen-and-treat programs to focus on strategies that can address incomplete registry systems, structural challenges in results delivery, cognitive barriers in understanding results and treatment, and work-related barriers.

Cervical cancer management in a low resource setting: A 10-year review in a tertiary care hospital in Kenya

Background

Cervical cancer is one of the leading causes of cancer mortality among women in Kenya due to late presentations, poor access to health care, and limited resources. Across many low- and middle-income countries infrastructure and human resources for cervical cancer management are currently insufficient to meet the high population needs therefore patients are not able to get appropriate treatment.

Objective

This study aimed to describe the clinicopathological characteristics and the treatment profiles of cervical cancer cases seen at Moi Teaching and Referral Hospital (MTRH).

Methods

This was a retrospective cross-sectional study conducted at MTRH involving the review of the electronic database and medical charts of 1541 patients with a histologically confirmed diagnosis of cervical cancer between January 2012 and December 2021.

Results

Of the 1541 cases analyzed, 91% were squamous cell carcinomas, 8% were adenocarcinomas, and 1% were other histological types. Thirty-eight percent of the patients were HIV infected and less than 30% of the women had health insurance. A majority (75%) of the patients presented with advanced-stage disease (stage IIB-IV). Only 13.9% received chemoradiotherapy with curative intent; of which 33.8% received suboptimal treatment. Of the 13% who received surgical treatment, 45.3% required adjuvant therapy, of which only 27.5% received treatment. Over 40% of the women were lost to follow-up.

Conclusion

Most of the patients with cervical cancer in Kenya present at advanced stages with only a third receiving the necessary treatment while the majority receive only palliative treatment or supportive care.

Challenges associated with follow-up care after implementation of an HPV screen-and-treat program with ablative therapy for cervical cancer prevention in Iquitos, Peru: a mixed methods study

Background

Cervical cancer is a preventable cancer; however, decreasing its prevalence requires early detection and treatment strategies that reduce rates of loss to follow-up. This study explores factors associated with loss to follow-up among HPV-positive women after implementation of a screen-and-treat approach with visual triage and ablative therapy for cervical cancer prevention in Iquitos, Peru.

Methods

We conducted semi-structured interviews with nurse-midwives (n = 15) working in cervical cancer prevention and women (n = 24) who were recorded as lost to follow-up after positive HPV results. We used the Health Care Access Barriers Model to guide analysis. We utilize manifest content analysis to describe barriers to follow-up according to the nurse-midwives and thematic analysis to report themes from the women's perspectives. We also report the steps and time taken to contact women and report discrepancies and concordances between nurse-midwives and women regarding reasons for loss to follow-up.

Results

Women in this study expressed a desire to receive treatment. Barriers, including fragmented and incomplete registry systems, made receiving follow-up care more challenging. Nurse-midwives faced structural barriers in attempting to deliver positive results to women who were challenging to contact, and women did not have clear knowledge of how to receive their HPV results. Women faced cognitive barriers including a lack of understanding about HPV results and treatment procedures, fear or anxiety about HPV or treatment, and confusion about the follow-up process. Women also reported having important work matters as a barrier. Reported financial barriers were minimal. There was agreement between women's and nurse-midwives' reported barriers to follow-up in slightly over half of the cases.

Conclusion

This study highlights the barriers to follow-up after implementation of a primary-level HPV-based screen-and-treat approach. While some barriers that have previously been associated with loss to follow-up were not observed in this study (e.g., financial), we emphasize the need for screen-and-treat programs to focus on strategies that can address incomplete registry systems, structural challenges in results delivery, cognitive barriers in understanding results and treatment, and work-related barriers.
