Willingness to pay brand premiums for generic medicines in Kenya: A bidding game experiment

BACKGROUND

Recent growth in the market share of higher priced branded generic medicines in low- and middle-income countries (LMICs) has raised concerns around affordability and access. We examined consumer willingness to pay (WTP) for branded versus unbranded generic non-communicable disease (NCD) medicines in Kenya.

METHODS

We randomly assigned NCD patients to receive a hypothetical offer for either a Novartis Access-branded medicine or for an unbranded generic equivalent. We then analysed WTP data captured using a bidding game methodology.

RESULTS

We found that WTP for Novartis Access medicines was on average 23% higher than for unbranded generic equivalents (p = 0.009). The WTP brand premium was driven almost entirely by wealthier patients.

CONCLUSIONS

Our findings suggest that the dominance of branded generics in LMICs like Kenya reflect in part consumer preferences for these medicines. Governments and other health sector actors may be justified in intervening to improve access to these medicines and equivalent non-branded generics, particularly for the poorest patients who appear to have no preference for branded medicines.

Midwifery centers as enabled environments for midwifery: A quasi experimental design assessing women's birth experiences in three models of care in Bangladesh, before and during covid

BACKGROUND

The midwifery model of care is a human rights-based approach (HRBA) that is unique and appropriate for the majority of healthy pregnant women, yet full expression may be limited within the medical model. Midwifery centers are facilities designed specifically to enable the practice of midwifery. In high resource countries, they have been shown to be cost effective, evidence-based, avoid over medicalization, and provide safe, efficient and satisfying care.

METHODS

A quasi-experimental design was used to assess the impact of three models of care on women's experiences of respect, and trust in maternity care provision, both before and during the pandemic in Bangladesh, as well as their fear and knowledge around COVID-19, during the pandemic. The models were: "fully enabled midwifery" ("FEM") in freestanding midwifery centers; "midwifery and medicine" ("MAM") in medical facilities with midwives working alongside nurses and doctors; and "no midwifery" ("NoM") in medical facilities without midwives. Phone survey data were collected and analyzed from all women (n = 1,191) who delivered from Jan 2020-June 2020 at seven health care facilities in Bangladesh. Comparison of means, ANOVA, post hoc Tukey, and effect size were used to explore the differences in outcomes across time periods.

FINDINGS

Pre-pandemic, women served by the FEM model reported significantly higher rates of trust and respect (p<0·001) compared to the NoM model, and significantly higher rates of trust (p<0·001) compared to MAM. During the pandemic, in the FEM model, the experiences of respect and trust did not change significantly from the pre-pandemic rates, and were significantly higher than both the MAM and NoM models (p < 0·001). Additionally, during the pandemic, women served by the FEM model had the lowest experience of COVID fear (p<0·001).

INTERPRETATION

Fully enabled midwifery in midwifery centers had a significantly positive effect on woman's experience of respect and trust in care compared to the other models, even in the context of a pandemic.

Household access to non-communicable disease medicines during universal health care roll-out in Kenya: A time series analysis

Objectives

This study aims to describe trends and estimate impact of county-level universal health coverage expansion in Kenya on household availability of non-communicable disease medicines, medicine obtainment at public hospitals and proportion of medicines obtained free of charge.

Methods

Data from phone surveillance of households in eight Kenyan counties between December 2016 and September 2019 were used. Three primary outcomes related to access were assessed based on patient report: availability of non-communicable disease medicines at the household; non-communicable disease medicine obtainment at a public hospital versus a different outlet; and non-communicable disease medicine obtainment free of cost versus at a non-zero price. Mixed models adjusting for fixed and random effects were used to estimate associations between outcomes of interest and UHC exposure.

Results

The 197 respondents with universal health coverage were similar on all demographic factors to the 415 respondents with no universal health coverage. Private chemists were the most popular place of purchase throughout the study. Adjusting for demographic factors, county and time fixed effects, there was a significant increase in free medicines (aOR 2.55, 95% CI 1.73, 3.76), significant decrease in medicine obtainment at public hospitals (aOR 0.68, 95% CI 0.47, 0.97), and no impact on the availability of non-communicable disease medicines in households (aβ -0.004, 95% CI -0.058, 0.050) with universal health coverage.

Conclusions

Access to universal health coverage caused a significant increase in free non-communicable disease medicines, indicating financial risk protection. Interestingly, this is not accompanied with increases in public hospitals purchases or household availability of non-communicable disease medicines, with public health centers playing a greater role in supply of free medicines. This raises the question as to the status of supply-side investments at the public hospitals, to facilitate availability of quality-assured medicines.

School-level Barriers of Antiretroviral Therapy Adherence and Interventions to Overcome them Among Adolescents Living with HIV in Western Kenya: A Qualitative Study

Background:

Adolescents in Kenya spend the majority of their time in a school environment. However, research to understand Antiretroviral Therapy (ART) adherence among adolescents living with HIV (ALWHIV) in school settings is sparse.

Objective:

To improve the design of appropriate interventions to better support this vulnerable population, the study aimed to explore school-related barriers to ART adherence experienced by ALWHIV.

Methods:

Qualitative data were utilized from a larger mixed-methods study on ALWHIV conducted at a major teaching and referral hospital in Kisumu, Kenya. Participants encompassed ALWHIV, their caregivers, teachers, and health care providers. Transcripts from a total of 24 in-depth interviews and five focus group discussions were analyzed in NVivo using a thematic approach.

Results:

Four themes emerged as key barriers in a school setting: negative experiences following HIV status self-disclosure, a strong desire for secrecy, restrictive school policies, and health education focused on sexual transmission of HIV. Participants suggested a range of potential interventions to better support ART adherence for ALWHIV, including coaching ALWHIV on disclosure strategies, promoting empathy among teachers and students, transition-preparing for ALWHIV, changing the narrative about HIV transmission in schools, providing water in schools, and introducing adherence support programs in schools, including the use of mobile technology.

Conclusion:

ALWHIV in Kenya experience numerous important challenges while trying to maintain optimal ART adherence in the school environment. Interventions that create supportive school settings are critical for better health outcomes among ALWHIV.

Probability and amount of medicines expenditure according to health insurance status in Kenya: A household survey in eight counties

Background

National and county governments in Kenya have introduced various health insurance schemes to protect households against financial hardship as a result of large health expenditure. This study examines the relationship between health insurance and medicine expenditure in eight counties in Kenya.

Methods

A cross‐sectional study of collected primary data via household survey in eight counties was performed. Three measures of medicine expenditure were analysed: the probability of any out‐of‐pocket expenditure (OOPE) on medicines in the last 4 weeks; amount of OOPE on medicines; and OOPE on medicines as a proportion of total OOPE on health.

Results

Out of the 452 individuals, those with health insurance (n = 225) were significantly different from individuals without health insurance (n = 227): overall, they were older, had a higher level of educational attainment and possessed more assets. Adjusting for covariates, individuals with health insurance had a reduced probability of OOPE on medicines (0.40, CI95% 0.197–0.827) and spent proportionally less on medicines out of total health expenditure (0.50, CI95% 0.301–0.926).

Conclusions

Kenya has made great strides to scale up Universal Health Coverage including access to medicines. Prioritising enrollment of low‐income individuals with non‐communicable diseases can accelerate access to medicines and financial protection.

Phone-based monitoring to evaluate health policy and program implementation in Kenya

Monitoring and evaluating policies and programs in low- and middle-income countries are often difficult because of the lack of routine data. High mobile phone ownership in these countries presents an opportunity for efficient data collection through telephone interviews. This study examined the feasibility of collecting data on medicines through telephone interviews in Kenya. Data on the availability and prices of medicines at 137 health facilities and 639 patients were collected in September 2016 via in-person interviews. Between December 2016 and December 2017, monthly telephone interviews were conducted with health facilities and patients. An unannounced in-person interview was conducted with respondents to validate the telephone interview within 24 h. A bottom-up itemization costing approach was used to estimate the costs of telephone and in-person data collection. In-depth interviews were conducted with data collectors and respondents to explore their perceptions on both modes of data collection. The level of agreement between data on medicines availability collected through phone and in-person interviews was strong at the health facility level [kappa = 0.90; confidence interval (CI) 0.88–0.92] and moderate at the household level (kappa = 0.50, CI 0.39–0.60). Price data from telephone and in-person interviews showed strong intra-class correlation at health facilities [intra-class correlation coefficient (ICC) = 0.96] and moderate intra-class correlation at households (ICC = 0.47). The cost per phone interview at health facilities and households were $19.73 and $16.86, respectively, compared to $186.20 for a baseline in-person interview. Participants considered telephone interviews to be more convenient. In countries with high cell phone penetration, telephone data collection should be considered in monitoring and evaluating public health programs especially at health facilities. Additional strategies may be needed to optimize this mode of data collection at the household level. Variations in cell phone ownership, telecommunication network and data collection costs across different settings may limit the generalizability of the findings from this study.

Coping with access barriers to non-communicable disease medicines: qualitative patient interviews in eight counties in Kenya

Background

There is rich literature on barriers to medicines access for the treatment of non-communicable diseases (NCDs) in high-income countries. Less is known about low- and middle-income countries, in particular the differences in coping with medicines access barrier by household wealth and disease. The aim of this study was to compare the coping mechanisms of patients with the lack of availability and affordability of cardio-vascular diseases, diabetes and asthma medicines in Kenya.

Methods

This qualitative study was part of a larger mixed methods evaluation study conducted in eight counties of Kenya from 2016 to 2019. Forty-nine patient interviews at study end line explored their NCD journey, perceptions of availability, stockouts and affordability of NCD medicines, their enrollment in health insurance, and their relationship with the private chemists. Transcribed interviews were coded using Nvivo software. A two-step thematic approach was used, first conducting a priority coding which was followed by coding emerging and divergent themes.

Results

Overall, we found that patients across all disease types and wealth level faced frequent medicine stock-outs at health facilities. In the absence of NCD medicines at health facilities, patients coped by purchasing medicines from local chemists, switching health facilities, requesting a different prescription, admitting oneself to an inpatient facility, establishing connections with local staff to receive notifications of medicine stock, stocking up on medicines, utilizing social capital to retrieve medicines from larger cities and obtaining funds from a network of friends and family. Categorizing by disease revealed patterns in coping choices that were based on the course of the disease, severity of the symptoms and the direct and indirect costs incurred as a result of stockouts of NCD medicines. Categorizing by wealth highlight differences in households’ capacity to cope with the unavailability and unaffordability of NCD medicines.

Conclusions

The type of coping strategies to access barriers differ by NCD and wealth group. Although Kenya has made important strides to address NCD medicines access challenges, prioritizing enrollment of low wealth households in county health insurance programs and ensuring continuous availability of essential NCD medicines at public health facilities close to the patient homes could improve access.

Availability and prices of medicines for non-communicable diseases at health facilities and retail drug outlets in Kenya: a cross-sectional survey in eight counties

OBJECTIVES

The objective of this study was to determine the availability and prices of medicines for non-communicable diseases (NCDs) in health facilities and private for-profit drug outlets in Kenya.

DESIGN

Cross-sectional study.

METHODS

All public and non-profit health facilities in eight counties (Embu, Kakamega, Kwale, Makueni, Narok, Nyeri, Samburu and West Pokot) that purchased medicines from the Mission for Essential Drugs and Supplies, a major wholesaler, were surveyed in September 2016. For each health facility, one nearby private for-profit drug outlet was also surveyed. Data on availability and price were analysed for 24 NCD and 8 acute medicine formulations. Availability was analysed separately for medicines in the national Essential Medicines List (EML) and those in the Standard Treatment Guidelines (STGs). Median price ratios were estimated using the International Medical Products Price Guide as a reference.

RESULTS

59 public and 78 non-profit facilities and 135 drug outlets were surveyed. Availability of NCD medicines was highest in private for-profit drug outlets (61.7% and 29.3% for medicines on the EML and STGs, respectively). Availability of STG medicines increased with increasing level of care of facilities: 16.1% at dispensaries to 31.7% at secondary referral facilities. The mean proportion of availability for NCD medicines listed in the STGs (0.25) was significantly lower than for acute medicines (0.61), p<0.0001. The proportion of public facilities giving medicines for free (0.47) was significantly higher than the proportion of private non-profit facilities giving medicines for free (0.09) (p<0.0001). The mean price ratio of NCD medicines was significantly higher than for acute medicines in non-profit facilities (4.1 vs 2.0, respectively; p=0.0076), and in private for-profit drug outlets (3.5 vs 1.7; p=0.0013).

CONCLUSION

Patients with NCDs in Kenya appear to have limited access to medicines. Increasing access should be a focus of efforts to achieve universal health coverage.

Access to asthma medicines at the household level in eight counties of Kenya

BACKGROUND

It is estimated that about 4 million Kenyans, i.e., 10% of the country's population, have asthma. We aimed to evaluate access to asthma medicines at the household level in eight counties of Kenya, including factors associated with location of purchase.

METHODS

Individuals with a diagnosis and prescription of asthma medicines were asked about the location of diagnosis, purchase of medicines, availability of medicines at home and costs of medicines per month. A logistic regression model explored the relationship between patient characteristics and the probability that the patient purchased asthma medicines at a public facility.

RESULTS

Of 128 (15.2%) individuals with a diagnosis of asthma who were receiving treatment, only 57.0% had asthma medicines at home. The most frequently purchased asthma medicine was salbutamol, with one third of individuals taking it orally instead of by inhalation. The majority (55.4%) purchased asthma medicines at private pharmacies. Female patients and lower socio-economic status were predictors of purchasing asthma medicines at public facilities.

CONCLUSIONS

The availability and affordability of asthma medicines remain significant barriers to access to care. Improving the availability and affordability of all asthma medicines in the public sector, including inhaled corticosteroids, offers the opportunity to reach vulnerable populations.

Effect of Novartis Access on availability and price of non-communicable disease medicines in Kenya: a cluster-randomised controlled trial

BACKGROUND

Novartis Access is a Novartis programme that offers a portfolio of non-communicable disease medicines at a wholesale price of US$1 per treatment per month in low-income and middle-income countries. We evaluated the effect of Novartis Access in Kenya, the first country to receive the programme.

METHODS

We did a cluster-randomised controlled trial in eight counties in Kenya. Counties (clusters) were randomly assigned to the intervention or the control group with a covariate-constrained randomisation procedure that maximised balance on a set of demographic and health variables. In intervention counties, public and non-profit health facilities were allowed to purchase Novartis Access medicines from the Mission for Essential Drugs and Supplies (MEDS). Data were collected from all facilities served by MEDS and a sample of households in study counties. Households were eligible if they had at least one adult patient who had been diagnosed and prescribed medicines for one of the non-communicable diseases targeted by the programme: hypertension, heart failure, dyslipidaemia, type 2 diabetes, asthma, or breast cancer. Primary outcomes were availability and price of portfolio medicines at health facilities, irrespective of brand; and availability of medicines at patient households. Impacts were estimated with intention-to-treat analysis. This trial is registered with ClinicalTrials.gov (NCT02773095).

FINDINGS

On March 8, 2016, we randomly assigned eight clusters to intervention (four clusters; 74 health facilities; 342 patients) or control (four clusters; 63 health facilities; 297 patients). 69 intervention and 58 control health facilities, and 306 intervention and 265 control patients were evaluated after a 15 month intervention period (last visit February 28, 2018). Novartis Access significantly increased the availability of amlodipine (adjusted odds ratio [aOR] 2·84, 95% CI 1·10 to 7·37; p=0·031) and metformin (aOR 4·78, 95% CI 1·44 to 15·86; p=0·011) at health facilities, but did not affect the availability of portfolio medicines overall (adjusted β [aβ] 0·05, 95% CI -0·01 to 0·10; p=0·096) or their price (aβ 0·48, 95% CI -1·12 to 0·72; p=0·500). The programme did not affect medicine availability at patient households (aOR 0·83, 95% CI 0·44 to 1·57; p=0·569).

INTERPRETATION

Novartis Access had little effect in its first year in Kenya. Access programmes operate within complex health systems and reducing the wholesale price of medicines might not always or immediately translate to improved patient access. The evidence generated by this study will inform Novartis's efforts to improve their programme going forward. The study also contributes to the public evidence base on strategies for improving access to medicines globally.

A qualitative analysis of decision-making among women with sexual violence-related pregnancies in conflict-affected eastern Democratic Republic of the Congo

BACKGROUND

Sexual violence is prevalent in conflict-affected settings and may result in sexual violence-related pregnancies (SVRPs). There are limited data on how women with SVRPs make decisions about pregnancy continuation or termination, especially in contexts with limited or restricted access to comprehensive reproductive health services.

METHODS

A qualitative study was conducted in Bukavu, Democratic Republic of the Congo (DRC) as part of a larger mixed methods study in 2012. Utilizing respondent-driven sampling (RDS), adult women who self-reported sexual violence and a resultant SVRP were enrolled into two study subgroups: 1) women currently raising a child from an SVRP (parenting group) and 2) women who terminated an SVRP (termination group). Trained female research assistants conducted semi-structured interviews with a subset of women in a private setting and responses were manually recorded. Interview notes were translated and uploaded to a qualitative software program, coded, and thematic content analysis was conducted.

RESULTS

A total of 55 women were interviewed: 38 in the parenting group and 17 in the termination group. There were a myriad of expressed attitudes, beliefs, and emotional responses toward SVRPs and the termination of SVRPs with three predominant influences on decision-making, including: 1) the biologic, ethnic, and social identities of the fetus and/or future child; 2) social reactions, including fear of social stigmatization and/or rejection; and 3) the power of religious beliefs and moral considerations on women's autonomy in the decision-making process.

CONCLUSION

Findings from women who continued and women who terminated SVRPs reveal the complexities of decision-making related to SVRPs, including the emotional reasoning and responses, and the social, moral, and religious dimensions of the decision-making processes. It is important to consider these multi-faceted influences on decision-making for women with SVRPs in conflict-affected settings in order to improve provision of health services and to offer useful insights for subsequent programmatic and policy decisions.

Study protocol for a cluster-randomised controlled trial of an NCD access to medicines initiative: evaluation of Novartis Access in Kenya

INTRODUCTION

Novartis recently launched Novartis Access, an initiative to provide a basket of reduced price medicines for non-communicable diseases (NCDs) to be sold through the public and private non-profit sectors in programme countries. This study will evaluate the impact of Novartis Access on the availability and price of NCD medicines at health facilities and households in Kenya, the first country to receive the programme.

METHODS AND ANALYSIS

This study will be a cluster-randomised controlled trial. 8 counties in Kenya will be randomly assigned to the intervention or control group using a covariate constrained randomisation method to maximise balance on demographic and health characteristics. In intervention counties, public and private non-profit health facilities will be able to order Novartis Access NCD medicines from the Mission for Essential Drugs and Supplies (MEDS). Data will be collected from a random sample of 384 health facilities and 800 households at baseline, midline after 1-year of intervention, and end-line after 2 years. Quarterly surveillance data will also be collected from health facilities and a subsample of households through phone-based interviews. Households will be eligible if at least one resident has been previously diagnosed and prescribed a medicine for an NCD addressed by Novartis Access, including hypertension and diabetes. The primary outcomes will be availability and price of NCD medicines at health facilities, and availability, price, and expenditures on NCD medicines at households. Impacts will be estimated using intention-to-treat analysis.

ETHICS AND DISSEMINATION

This protocol was approved by the Institutional Review Boards at Strathmore University and at Boston University. Informed consent will be obtained from all participants at the start of the trial. The findings of the trial will be disseminated through peer-reviewed journals, international conferences, and meetings and events organised with local stakeholders.

TRIAL REGISTRATION NUMBER

A quantitative assessment of termination of sexual violence-related pregnancies in eastern Democratic Republic of Congo

BACKGROUND

Sexual violence is prevalent in eastern Democratic Republic of Congo (DRC), and has resulted in sexual violence-related pregnancies (SVRPs). Despite restrictive laws, women may seek to terminate SVRPs; however, there are limited data on termination of SVRPs.

METHODS

A mixed methods study was conducted in 2012 in Bukavu, DRC. Adult women who self-reported an SVRP and termination of that SVRP were recruited using respondent-driven sampling (RDS). Trained female interviewers verbally administered a quantitative survey to all participants and a semi-structured qualitative survey to a subset. Quantitative data on characteristics and complications of pregnancy termination, including mental health outcomes, were analyzed using SAS.

RESULTS

In total, 86 women completed quantitative surveys. Most SVRPs (93 %) involved two or more assailants; 73 % occurred while in captivity. Most women (82 %) terminated the SVRPs at 3 months gestation or earlier; 79 % reported one attempt at pregnancy termination and 21 % more than one attempt. The most common methods of termination were an oral medicine (55 %) or herb (35 %); cimpokolo (31 %) and quinine (18 %) were most frequently reported. These methods were accessed through friends (37 %), healthcare providers (18 %), family (16 %), or self-obtained (12 %). Following the termination, 79 % of women reported subsequent physical symptoms, including abdominal pain (74 %), bleeding (47 %), vaginal discharge (35 %) and fever (18 %); 44 % sought medical care for their symptoms. Varied emotional responses to the termination were reported and included relief (34 %), anxiety (21 %), anger (19 %), guilt (19 %), and regret (10 %). At the time of the study, many women met symptom criteria for post-traumatic stress disorder (57 %), depression (50 %), and generalized anxiety disorder (33 %).

CONCLUSION

Most women terminated SVRPs using medications or herbs not recognized as evidence-based methods of pregnancy termination and sought these methods outside of the formal healthcare sector. These data suggest that access to safe abortion methods is needed for women with SVRPs in DRC. Physical symptoms and emotional reactions related to the termination varied. While it is not possible to differentiate the impacts of sexual violence, SVRP, and pregnancy termination on mental health outcomes, the findings highlight the complex needs of women with SVRPs and opportunities for integrative health services.

Awareness, knowledge and beliefs about HPV, cervical cancer and HPV vaccines among nurses in Cameroon: an exploratory study

BACKGROUND

While it is known that sub-Saharan African countries face multiple obstacles such as cost in adopting vaccination against human papillomavirus (HPV), the crucial role nurses can play in implementing such programs has not been adequately examined.

OBJECTIVES

To investigate the knowledge and awareness of HPV, primary cause of cervical cancer and HPV vaccine among nurses working at four Cameroon Baptist Convention Health Services facilities, and to explore what factors influence nurses' willingness to inform and recommend HPV vaccine to adolescents and parents attending clinics.

DESIGN AND SETTING

A structured questionnaire survey was administered to a convenience sample of nursing staff working at the four health facilities.

RESULTS

Of 192 eligible nurses 76 (39.6%) participated in the study. There were moderately low levels of knowledge about HPV infection and prevention of cervical cancer, but a moderately high level of knowledge about HPV vaccine. Although 90.8% acknowledged that cervical cancer is directly linked to HPV infection, nearly 32% failed to identify it as a sexually transmitted infection (STI), while 43.4% believed it is an uncommon infection. Willingness to recommend the HPV vaccine was moderate, with 69.7% intentionally initiating discussions with patients about the subject. The most important factors considered when deciding to recommend the vaccine included effectiveness (56.6%) and side effects/safety (11.8%). Cost was less of a concern (6.6%), likely due to the availability of donated vaccine.

CONCLUSION

Despite high awareness about HPV, more education about the virus, cervical cancer and the vaccine are required to further increase nurses' willingness to recommend the vaccine and strengthen strategies for reaching adolescents through nurses in Cameroon.

Factors that influence male involvement in sexual and reproductive health in western Kenya: a qualitative study

This study explored factors that influence male involvement in reproductive health in western Kenya. Qualitative study design was used. From December 2008 to February 2009, data were collected via in-depth interviews and focus group discussions (FGDs) at three provinces of western Kenya. Twelve in-depth interviews and eight FGDs were conducted. Five participants in in-depth interviews were female, seven were male. Four of the FGDs had all-male participants, four all-female. The factors that influence male involvement in reproductive health emerged in two themes, namely gender norms and the traditional approaches used to implement reproductive health and family planning programs. Any strategy taken to involve men in reproductive health must therefore consider addressing these two factors. A review of the traditional approaches of implementing reproductive health is necessary to make them more male-friendly.
