How effective was implementation of the package of essential non-communicable disease (PEN) interventions: A review of evidence?

Health seeking behaviours and private sector delivery of care for non-communicable diseases in low- and middle-income countries: a systematic review

BACKGROUND

Globally, non-communicable diseases (NCDs) are the leading cause of mortality and morbidity placing a huge burden on individuals, families and health systems, especially in low- and middle-income countries (LMICs). This rising disease burden calls for policy responses that engage the entire health care system. This study aims to synthesize evidence on how people with NCDs choose their healthcare providers in LMICs, and the outcomes of these choices, with a focus on private sector delivery.

METHODS

A systematic search for literature following PRISMA guidelines was conducted. We extracted and synthesised data on the determinants and outcomes of private health care utilisation for NCDs in LMICs. A quality and risk of bias assessment was performed using the Mixed Methods Appraisal Tool (MMAT).

RESULTS

We identified 115 studies for inclusion. Findings on determinants and outcomes were heterogenous, often based on a particular country context, disease, and provider. The most reported determinants of seeking private NCD care were patients having a higher socioeconomic status; greater availability of services, staff and medicines; convenience including proximity and opening hours; shorter waiting times and perceived quality. Transitioning between public and private facilities is common. Costs to patients were usually far higher in the private sector for both inpatient and outpatient settings. The quality of NCD care seems mixed depending on the disease, facility size and location, as well as the aspect of quality assessed.

CONCLUSION

Given the limited, mixed and context specific evidence currently available, adapting health service delivery models to respond to NCDs remains a challenge in LMICs. More robust research on health seeking behaviours and outcomes, especially through large multi-country surveys, is needed to inform the effective design of mixed health care systems that effectively engage both public and private providers.

Effectiveness of behavioural change interventions on physical activity, diet and body mass index of public primary healthcare users in Kosovo: the KOSCO cohort

BACKGROUND

Prevalent physical inactivity and poor nutrition contribute to high non-communicable disease (NCD) morbidity and mortality in Kosovo. To improve health services for patients with NCD the Accessible Quality Healthcare project developed behaviour change interventions following the principles of the WHO Package of Essential NCD (PEN) protocol. They were implemented into the public primary healthcare (PHC) system of five early-stage implementation municipalities (ESIM, 2018) and seven late-stage implementation municipalities (2020).

OBJECTIVE

To assess the effect of the behaviour change interventions; motivational stages of behaviour change for physical activity and nutrition; and body mass index (BMI).

DESIGN

Prospective cohort study.

DATA COLLECTION AND ANALYSIS

We included 891 public PHC users aged 40 years and above, who were enrolled in the KOSCO (Kosovo Non-Communicable Disease Cohort) cohort in 2019 and followed-up biannually until February 2021. The PHC users who consulted for themselves any health service were approached and recruited for cohort participation. Each participant contributed up to four self-reports of nutrition and physical activity, and up to three reports of motivation to change for a better lifestyle. These outcomes were modelled prospectively with robust mixed-effects Poisson regressions. The association between behaviour change interventions and BMI was quantified using linear regression.

RESULTS

There was a high rate of smokers 20.5% and obesity 53.1%, and high rates of self-reported diagnoses of diabetes: 57.1%; hypertension 62.6%. We found no effect of residing in an ESIM, but adherence to both guidelines was higher in ESIM at the latest follow-up time point. ESIM residence was also associated with a twofold increase in the probability of reporting a high motivation for a better lifestyle and with a statistically non-significant decrease in BMI of -0.14 kg/m2 (95% CI: -0.46 to 0.19) at the latest follow-up.

CONCLUSION

The longitudinal results extend evidence on the effect of WHO PEN protocol in promoting physical activity and nutritional behaviour in the Kosovo context.

Implementing a package of essential non-communicable diseases interventions in low- and middle-income countries: a realist review protocol

INTRODUCTION

The burden of non-communicable diseases (NCDs) is increasing rapidly, particularly in low- and middle-income countries (LMIC), accounting for 85% of premature deaths in the region. LMICs have been facing an increasing trend of a double burden of disease (infectious diseases and NCDs) that has led to multiple challenges in prioritising strategies for NCDs control amidst limited resources. Evidence indicates that measures such as the WHO's package of essential non-communicable (PEN) diseases interventions can prevent and control NCDs. However, because of the complexity of such health interventions, there is limited evidence that explains how the intervention works, for whom and in what context. We aim to unpack the causal mechanisms explaining how, why, for whom and in what context PEN prevents and controls NCDs.

METHODS AND ANALYSIS

We propose a realist review to understand how, why, for whom and under what circumstances PEN works or does not work. The review process includes five steps applied iteratively throughout the study: clarification of review scope, searching for evidence, appraising and extracting data, synthesising evidence and drawing conclusions, and disseminating the findings. Programme theories will be developed using the realist logic for theory formulation-Retroductive Theorising. The context-mechanism-outcome (CMO) heuristic tool will be used to develop the programme theories. Portions of the reviewed documents describing constructs of context, mechanism and outcomes will be coded inductively and extracted. These extracted constructs will then be linked abductively to formulate CMO configurations.

ETHICS AND DISSEMINATION

Formal ethical approval is not required for this review. Study findings will be disseminated through publications in peer-reviewed journals, conference presentations and formal and informal reports.

Optimizing cardiovascular disease risk screening in a low-resource setting: cost-effectiveness of program modifications in Sri Lanka modelled with nationally representative survey data

BACKGROUND

While screening for cardiovascular disease (CVD) risk can help low-resource health systems deliver low-cost, effective prevention, evidence is needed to adapt international screening guidelines for maximal impact in local settings. We aimed to establish how the cost-effectiveness of CVD risk screening in Sri Lanka varies with who is screened, how risk is assessed, and what thresholds are used for prescription of medicines.

METHODS

We used data for people aged 35 years and over from a 2018/19 nationally representative survey in Sri Lanka. We modelled the costs and quality adjusted life years (QALYs) for 128 screening program scenarios distinguished by a) age group screened, b) risk tool used, c) definition of high CVD risk, d) blood pressure threshold for treatment of high-risks, and e) prescription of statins to all diabetics. We used the current program as the base case. We used a Markov model of a one-year screening program with a lifetime horizon and a public health system perspective.

RESULTS

Scenarios that included the WHO-2019 office-based risk tool dominated most others. Switching to this tool and raising the age threshold for screening from 35 to 40 years gave an incremental cost-effectiveness ratio (ICER) of $113/QALY. Lowering the CVD high-risk threshold from 20 to 10% and prescribing antihypertensives at a lower threshold to diabetics and people at high risk of CVD gave an ICER of $1,159/QALY. The findings were sensitive to allowing for disutility of daily medication.

CONCLUSIONS

In Sri Lanka, CVD risk screening scenarios that used the WHO-2019 office-based risk tool, screened people above the age of 40, and lowered risk and blood pressure thresholds would likely be cost-effective, generating an additional QALY at less than half a GDP per capita.

Analysing the Influence of WHO Initiatives on the Scientific Discourse of Noncommunicable Diseases through a Bibliometric Approach

Noncommunicable diseases (NCDs) present a major public health challenge, prompting their inclusion in the United Nations' 2030 Agenda for Sustainable Development. In response, the World Health Organization (WHO) has implemented various initiatives, including a comprehensive monitoring framework with global targets and indicators. However, the extent to which these initiatives have shaped the scientific discourse remains unclear. This article addresses this knowledge gap through a two-fold approach. Firstly, a bibliometric analysis of 14,187 studies spanning over 60 years is conducted, identifying key contributors and trends. Secondly, the content analysis compares these trends to the goals established by the WHO. The findings indicate that the WHO initiatives have accelerated scientific research, and elevated global targets and indicators as central themes in scholarly discussions, since 2011. This study takes an innovative approach that contributes to the advancement of knowledge in this field, by providing valuable insights into the impact of WHO initiatives on the scientific debate surrounding NCDs, and offering guidance for policymakers, researchers, and stakeholders engaged in combating these diseases.

Participation in community-based healthcare interventions and non-communicable diseases early detection of general population in Indonesia

Background

Community-based Healthcare Interventions (CBHIs) are regarded as a critical component of healthcare task-sharing in LMICs and have the potential to address LMICs’ health system weaknesses to improve NCDs prevention care. This study aims to investigate the relationship between participation in CBHIs and NCDs early detection at medical facilities among Indonesians.

Methods

Data come from the fifth Indonesian Family Life Survey (2014–2015), a total of 27,692 individuals (14,820 female and 12,872 male individuals age 15 and older). Multiple ordered logistics and logistics regression was used to assess the association between individual participation in CBHI and early detection of NCDs at medical facilities.

Findings

Participation in CBHIs are associated with higher odds of having regular blood pressure test (adjusted odds ratio [OR], 3.09; 95% confidence interval [CI], 2.67–3.58), cholesterol test (adjusted OR, 1.88; 95% CI, 1.60–2.22), blood glucose test (adjusted OR, 1.88; 95% CI, 1.58–2.23), electrocardiogram (adjusted OR, 1.37; 95% CI, 1.06–1.76) and basic dental examination (adjusted OR, 1.32; 95% CI, 1.09–1.60) at medical facilities. The odds of having pap smears (adjusted OR, 2.20; 95% CI, 1.62–2.98) and breast self-examination (adjusted OR, 1.73; 95% CI, 1.37–2.19) among females who participated in CBHIs are substantially larger than those who did not participate in CBHIs. No significant association is shown for the basic vision examination (adjusted OR, 1.14; 95% CI, 0.95–1.37), while the association of participation in CBHIs on prostate cancer checkup (adjusted OR, 0.18; 95% CI, 0.04–0.76) was negative and significant. The results were controlled with a wide range of predisposing, enabling and need factors for NCDs early detection.

Conclusion

and recommendation: CBHIs may benefit NCDs early detection for the general population in Indonesia. Policymakers and health practitioners need to design CBHIs programs that are attractive to the population, especially men and younger people.
