Abstract

Background

Family planning is a central component of reproductive health and contributes to reductions in maternal and child mortality. While most evidence in Ethiopia is derived from household surveys, limited attention has been given to service delivery at the point of care. This study examines determinants of receipt of family planning services during facility visits using nationally sampled Service Provision Assessment (SPA) survey data.

Methods

A facility-based cross-sectional analysis was conducted using nationally implemented SPA survey data. The survey employed a stratified multistage sampling design, in which health facilities were selected within strata defined by region, managing authority, and facility type, followed by systematic sampling of clients within facilities for exit interviews. The study included 2,588 women aged 15–49 years who attended sampled facilities and completed client exit interviews. The outcome was receipt of any family planning service during the visit, defined as provision of counseling and/or a contraceptive method, reflecting service delivery at the point of care rather than contraceptive use. Multivariable logistic regression was used to assess associations between client characteristics, provider attributes, and facility-level factors. Exploratory interaction analyses were conducted but not retained in the final model due to instability and sparse data structures. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were reported, and statistical significance was defined at a two-sided p-value < 0.05. All analyses were conducted using R (version 4.5.3).

Results

Overall, 64.2% of clients received a family planning service during their visit. After adjustment, clients without prior contact with a provider had higher odds of receiving a service compared with those reporting prior contact (AOR = 2.25; 95% CI: 1.86–2.72; p < 0.001). Married women had lower odds of receiving a service than single women (AOR = 0.69; 95% CI: 0.49–0.98; p = 0.030). Substantial regional variation was observed, with lower odds in Amhara (AOR = 0.29; 95% CI: 0.17–0.49) and Addis Ababa (AOR = 0.41; 95% CI: 0.23–0.73), and higher odds in Benishangul-Gumuz, Gambella, and Dire Dawa. Other covariates were not statistically significant after adjustment, and observed associations should be interpreted as reflecting service delivery processes at the point of care rather than underlying contraceptive demand.

Conclusions

Family planning service receipt during facility visits in Ethiopia is associated with prior client–provider contact, marital status, and regional context. The persistence of regional differences after adjustment indicates that contextual factors related to health system performance and service delivery environments play a role in shaping service delivery during clinical encounters. The findings indicate heterogeneity in service delivery at the point of care, suggesting the need for context-specific strategies to improve the consistency and quality of family planning services within health facilities.

Introduction

Family planning (FP) is a core component of reproductive health, enabling individuals to achieve the desired fertility and spacing of births through the use of contraceptive methods. Extensive evidence demonstrates that contraceptive use reduces maternal mortality, prevents unintended pregnancies, and improves child health outcomes, particularly in low- and middle-income countries (LMICs) [1,2].

Despite these benefits, the utilization of family planning services remains uneven. Both demand-side factors such as fertility preferences, sociocultural norms, and knowledge and supply-side factors, including service availability, provider competence, and quality of care contribute to this variation [3,4]. Increasingly, research highlights that the quality of care and the nature of provider–client interactions play a critical role in shaping contraceptive uptake and continuation, beyond mere access to services [57].

Ethiopia has made substantial progress in expanding access to family planning through the strengthening of primary healthcare and the Health Extension Program. National surveys indicate increasing contraceptive prevalence over time; however, marked regional disparities persist, reflecting heterogeneity in health system performance, access to services, and sociocultural context [8]. Policy initiatives such as the Family Planning Costed Implementation Plan (FP-CIP 2023–2030) aim to address these gaps by improving service coverage and reducing unmet need [9].

Most existing evidence in Ethiopia is derived from household surveys, particularly the Demographic and Health Surveys (EDHS), which measure self-reported contraceptive use and emphasize individual- and household-level determinants [10,11]. While these data are essential for monitoring population-level outcomes, they fail to capture whether family planning services are actually delivered during facility visits and do not provide detailed information on provider behavior and service delivery processes at the point of care.

Facility-based data provide a complementary perspective. The Ethiopian Service Provision Assessment (SPA) survey integrates facility audits, provider interviews, and client exit interviews, enabling measurement of reported service receipt at the point of care [12]. This design allows examination of how client characteristics, provider attributes, and facility-level factors jointly influence whether family planning services are delivered during a visit an outcome that is conceptually distinct from population-level contraceptive use [13]. Regional variation in health system capacity, provider practices, and service environments in Ethiopia suggests that service delivery processes may differ across contexts. These differences provide a theoretical basis for examining whether associations between client characteristics and service receipt vary across regions and facility settings, even when overall service availability is similar [14].

However, empirical evidence using SPA data to examine factors influencing the receipt of family planning services in Ethiopia remains limited. In particular, there is a need to better understand how client, provider, and facility-level factors are associated with the delivery of services during facility visits and how these relationships reflect broader health system performance.

Therefore, this study uses nationally implemented SPA survey data to examine the factors that influence the receipt of family planning services during facility visits in Ethiopia. Specifically, the study aims to identify client, provider, and facility-level factors associated with receipt of family planning services during the visit and assess the extent of regional variation in service delivery. By focusing on observed service delivery at the point of care, the study provides a proximal measure of health system performance and contributes to a more precise understanding of how service delivery processes influence the receipt of family planning within health facilities.

Materials and methods

Study design and data source

This study employed a facility-based cross-sectional design using data from the 2021–2022 Ethiopian Service Provision Assessment (SPA) survey conducted under the Demographic and Health Surveys (DHS) Program. The SPA survey is a nationally implemented health facility assessment designed to capture information on service availability, readiness, and quality across public and private health facilities. The survey combines different types of data, such as inventories of facilities, interviews with health providers, and exit interviews with clients. The present analysis was based exclusively on the dataset from client exit interviews, which provides standardized information on services received during a single facility visit and on client provider interactions observed at the point of care. The SPA dataset was obtained from the DHS Program following standard procedures. All data are fully anonymized, and no personal identifiers are available to researchers.

Study setting

The study covered health facilities across all administrative regions of Ethiopia, including both public and private institutions. The dataset reflects diverse geographic, socioeconomic, and health system contexts, ensuring broad representativeness of service delivery environments.

Study population

The study population consisted of women aged 15–49 years who attended sampled health facilities and were included in the SPA client exit interview at facilities offering family planning services. The inclusion reflects attendance at facilities where FP services were available and participation in the exit interview. Only one observation per client visit was included, consistent with the SPA design, where each exit interview corresponds to a single service encounter. A total of 2,588 women were included in the analysis, of whom 1,662 (64.2%) received at least one family planning service during their facility visit.

Sampling procedure

The Ethiopian SPA survey employed a stratified multistage sampling design. Health facilities were stratified by region, managing authority (public or private), and facility type (hospital, health center, clinic, and health post). Facilities were then randomly selected within strata to ensure nationally implemented in service delivery environments. Within each selected facility, eligible clients were systematically sampled on the day of data collection and interviewed immediately after receiving services. This approach minimizes recall bias and ensures that reported services correspond to actual care received during the observed visit.

The regression analysis did not include sampling weights or complex survey design elements like clustering and stratification. The data from client exit interviews represent facility-based service encounters rather than a population-based sample of women. Accordingly, the analysis focuses on associations within observed service delivery settings. Estimates may be subject to bias in variance estimation and generalizability, and findings should not be interpreted as nationally representative.

Study variables

Outcome variable.

The outcome variable was defined as receipt of a family planning (FP) service during the facility visit, based on data from client exit interviews in the Service Provision Assessment (SPA) survey. It was coded as a binary variable (Yes/No). A client was classified as having received an FP service if, during the visit, the client reported receiving FP counseling or information and/or a contraceptive method, prescription, or referral.

Within the SPA framework, this measure reflects observed service delivery at the point of care rather than confirmed adoption, continuation, or sustained use of contraception. The outcome combines distinct service components, including counseling-only encounters and method provision. For fertility-awareness–based (natural) methods, “receipt” reflects counseling or information provision rather than physical delivery of a method. Although this composite definition follows the SPA measurement structure, it aggregates service components that may have different underlying determinants. Therefore, findings should be interpreted as reflecting overall service delivery at the visit rather than specific contraceptive behaviors such as initiation, continuation, or adherence.

Explanatory variables.

Explanatory variables were selected based on theoretical relevance to health service utilization and availability within the SPA dataset. These included client-level characteristics (educational status, marital status, number of pregnancies, and place of residence), provider-level characteristics (sex of the provider), and facility/service-related characteristics (facility type, prior client–provider contact, and region).

Categorical variables were coded using appropriate reference categories to facilitate interpretation of regression coefficients. Sparse categories, particularly within marital status and regional classifications, were carefully evaluated; however, categories were retained where analytically meaningful and supported by sufficient sample size to avoid over-collapsing and loss of interpretability.

Statistical analysis

All analyses were conducted using R statistical software (version 4.5.3). Descriptive statistics were first computed to summarize the distribution of study variables. Categorical variables were reported as frequencies and percentages, while continuous variables were summarized using means and standard deviations or medians and interquartile ranges, as appropriate.

Descriptive analyses were conducted using unweighted data and did not incorporate clustering, stratification, or sampling weights because the primary objective was to examine conditional associations between client, provider-, and facility-level characteristics and receipt of family planning services during facility visits rather than to estimate nationally representative prevalence measures. Accordingly, the analysis followed a model-based inferential framework focused on within-sample associations using observed SPA facility-visit data. Methodological literature has emphasized that the appropriateness of survey weighting in regression analyses depends on the analytic objective and inferential target. Solon et al. noted that weighting is primarily required for descriptive population estimation and may not be necessary when the objective is estimation of conditional relationships and relevant design-related covariates are included in the model [15]. Similarly, Beaumont argued that inclusion of variables associated with the sampling process may reduce the need for design weights in regression analyses of conditional relationships [16]. Additional methodological work has further indicated that weighted regression models can reduce statistical efficiency when the primary objective is association modeling rather than descriptive population inference [17,18]. Consistent with these recommendations, major design-related covariates, including region, facility type, residence, and provider characteristics, were incorporated directly into the regression model to account for contextual heterogeneity. Nevertheless, findings should be interpreted as estimates of associations within the analyzed SPA facility-visit sample rather than nationally representative population parameters.

Differences in characteristics between clients who did and did not receive family planning (FP) services during the visit were assessed using Pearson’s chi-square tests for categorical variables and Wilcoxon rank-sum tests for continuous variables. To complement hypothesis testing, effect sizes were reported using Cramér’s V for categorical variables and rank-biserial correlation for continuous variables.

Standardized mean differences (SMDs) were additionally calculated to assess covariate imbalance between outcome groups. For continuous variables, SMDs were computed by standardizing mean differences using pooled standard deviations, whereas for categorical variables multivariate extensions based on category proportions were applied. SMDs are recommended as scale-independent measures of group imbalance because they are less influenced by sample size than conventional significance tests. Consistent with commonly used recommendations in observational and epidemiologic research, SMD values around 0.10, 0.20, and 0.50 were interpreted as indicating small, moderate, and large imbalance, respectively [1921].

A multivariable logistic regression model was fitted to examine the association between explanatory variables and receipt of FP services during the visit. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were reported. Statistical significance was assessed using a two-sided alpha level of 0.05.

The model specification was defined as:

where represents the binary outcome for the client , represents the k-th explanatory variable, and represents regression coefficients.

Selection of covariates was guided by theoretical relevance to health service utilization and data availability within the SPA framework. Interaction terms between prior client–provider contact and contextual variables (region and facility type) were explored based on hypothesized effect heterogeneity. However, these interaction models exhibited substantial multicollinearity and sparse-data structures, leading to unstable parameter estimates and reduced interpretability. Therefore, the final analysis is based on the main-effects model.

Model diagnostics were conducted to assess the adequacy of the fitted model. Multicollinearity was evaluated using variance inflation factors (VIF), with values below 5 indicating no evidence of problematic collinearity, consistent with commonly applied recommendations in regression modeling studies [22]. The potential influence of individual observations was examined using Cook’s distance and leverage diagnostics.

Model fit was assessed using deviance statistics and the Akaike Information Criterion (AIC) to compare alternative specifications [23]. Discriminatory ability was evaluated using the area under the receiver operating characteristic curve (AUC), and calibration was assessed using the Brier score and calibration plots. These measures were interpreted as indicators of predictive performance and model stability, rather than evidence of causal validity. To enhance interpretability, average marginal effects (AMEs) were computed to quantify the change in predicted probability of receiving FP services associated with each explanatory variable, holding other variables constant [24,25].

Given the potential for endogeneity, particularly for prior client–provider contact, which may proxy unobserved characteristics such as underlying demand for family planning, all estimated associations are interpreted as non-causal. Results are reported in accordance with established guidelines for observational studies to ensure transparency and reproducibility.

Ethical considerations

The study uses publicly available SPA data obtained with authorization from the DHS Program. Ethical approval for the original survey was obtained by the Ethiopian Public Health Institute Institutional Review Board and the ICF Institutional Review Board, and the survey was conducted in accordance with the ethical principles outlined in the Declaration of Helsinki. Permission to access and use the SPA 2021–2022 data was formally obtained from the DHS Program following an approved data request. The dataset used for this analysis is fully anonymized and publicly available; therefore, no additional ethical approval or informed consent was required for the present study.

Results

Study population and outcome distribution

A total of 2,588 women aged 15–49 years who attended sampled health facilities were included in the analysis. Among these, 1,662 (64.2%) reported receiving a family planning (FP) service during the visit, while 926 (35.8%) did not receive any FP service.

Descriptive characteristics of study participants

Table 1 presents the distribution of study participants according to receipt of family planning (FP) services during the facility visit. Several variables, including educational status, number of pregnancies, provider sex, and place of residence, showed minimal imbalance between outcome groups (standardized mean difference [SMD] < 0.10).

Table 1. Characteristics of study participants by family planning service receipt.

https://doi.org/10.1371/journal.pone.0352145.t001

In contrast, greater covariate imbalance was observed for prior client–provider contact (SMD = 0.32) and region (SMD = 0.63), indicating meaningful differences between women who did and did not receive FP services during the visit. Facility type (p < 0.001) and marital status (p = 0.01) also differed between groups, although the magnitude of imbalance was comparatively smaller.

Women who received FP services were more frequently observed in hospitals than women who did not receive FP services. Prior client–provider contact was descriptively more common among women who received FP services (74.0%) than among those who did not receive services (59.1%). However, this unadjusted distribution differed from the direction of the adjusted association observed in the multivariable model, indicating that the association appeared to vary according to the distribution of other covariates across groups. Marked regional variation in service receipt was also observed.

Bivariate associations and effect size assessment

Table 2 summarizes bivariate associations between explanatory variables and receipt of FP services during the visit. Statistically significant associations were observed for facility type (χ² = 22.17, p < 0.001) and prior client–provider contact (χ² = 60.43, p < 0.00). Marital status was also associated with the outcome based on Fisher’s exact test (p = 0.01). No statistically significant associations were identified for educational status (p = 0.57), provider sex (p = 0.11), place of residence (p = 0.20), or number of pregnancies (p = 0.56).

thumbnail
Table 2. Bivariate associations with family planning service receipt.

https://doi.org/10.1371/journal.pone.0352145.t002

Effect size estimates indicated a moderate association for prior client–provider contact (Cramér’s V = 0.15) and a small association for facility type (Cramér’s V = 0.09), while the effect size for number of pregnancies was negligible (rank-biserial correlation = 0.01).

Regional variation in family planning service receipt

Region was summarized separately to improve readability of the primary bivariate comparison table and to avoid disproportionate expansion of the table due to the large number of regional categories. Regional variation in receipt of FP services during facility visits is presented in Table 3. A statistically significant association was observed between region and service receipt (χ² = 236.60, df = 10, p < 0.001), with a moderate effect size (Cramér’s V = 0.30), indicating substantial variation across regions.

Table 4 present crude association between previous contact and FP service receipt. In unadjusted analysis, women without prior client–provider contact had significantly lower odds of receiving FP services during the visit compared with women who had prior contact (crude OR = 0.51; 95% CI: 0.43–0.60; p < 0.001). However, after adjustment for region, facility type, marital status, and other covariates, the direction of association reversed in the multivariable model.

Multivariable logistic regression analysis

Table 5 presents adjusted associations between explanatory variables and receipt of FP services during the visit. After adjustment for region, facility type, marital status, and other covariates, the direction of association reversed, with women without prior contact demonstrating higher adjusted odds of receiving FP services during the visit (AOR = 2.25; 95% CI: 1.86–2.72; p < 0.001). This direction differed from the descriptive distribution observed in Table 1, suggesting that adjustment for contextual and facility-related covariates reversed the direction of the association. Marital status was also associated with service receipt. Married women had lower odds of receiving FP services compared with single women (AOR = 0.69; 95% CI: 0.49–0.98; p = 0.03), while other marital categories were not statistically significant.

thumbnail

https://doi.org/10.1371/journal.pone.0352145.t005

Substantial regional variation persisted after adjustment. Compared with Afar, women attending facilities in Benishangul-Gumuz (AOR = 3.77; 95% CI: 1.95–7.28), Gambella (AOR = 2.96; 95% CI: 1.67–5.24), and Dire Dawa (AOR = 3.04; 95% CI: 1.50–6.15) had higher adjusted odds of receiving FP services during the visit. In contrast, lower odds were observed in Amhara (AOR = 0.29; 95% CI: 0.17–0.49) and Addis Ababa (AOR = 0.41; 95% CI: 0.23–0.73). Confidence intervals for some regions were wider, indicating reduced precision. These adjusted regional estimates reflect conditional associations after accounting for differences in client, provider, and facility characteristics and therefore may differ from the crude descriptive distributions presented in Table 1. There were no statistically significant links between educational status, number of pregnancies, type of facility, provider sex, or place of residence.

Predicted probabilities and marginal effects

Predicted probabilities and marginal effects were consistent with regression findings, demonstrating differences in service receipt across prior client–provider contact and region (Fig 1 and Fig 2).

https://doi.org/10.1371/journal.pone.0352145.g002

Women without prior contact had a 17.1 percentage point higher probability of receiving FP services compared with those with prior contact (AME = 0.17; 95% CI: 0.132–0.21; p < 0.001). Married women had a 7.8 percentage point lower probability compared with single women (AME = −0.08; 95% CI: −0.15 to −0.00; p = 0.04). Regional marginal effects were directionally consistent with regression estimates (Table 6). Average marginal effects were estimated from the fitted multivariable logistic regression model. It was presented to improve interpretability of adjusted probability differences.

Interaction effects (Sensitivity analysis)

Table 7 presents likelihood ratio tests for interaction effects. No evidence of interaction was observed between prior client–provider contact and facility type (χ² = 1.18, df = 3, p = 0.76).

Table 7. Likelihood ratio tests for interaction effects on FP service receipt.

https://doi.org/10.1371/journal.pone.0352145.t007

Although the likelihood ratio test suggested a statistically significant interaction between prior contact and region (χ² = 244.93, df = 10, p < 0.001), the interaction model produced unstable estimates characterized by inflated standard errors, sparse cell counts, and reduced interpretability. Therefore, interaction terms were not retained, and the main-effects model was selected for final interpretation.

Model diagnostics and performance

Model diagnostics showed no evidence of problematic multicollinearity or influential observations (S1 Table, S1 Fig, S2 Fig). The model demonstrated acceptable discriminative ability (AUC = 0.72; 95% CI: 0.70–0.74) and satisfactory calibration (Brier score = 0.20) (S3 Table, S3 Fig, S4 Fig). Cross-validation results showed similar raw and adjusted prediction error estimates (S2 Table). Detailed diagnostic results are provided in the Supplementary Material.

Discussion

This study provides facility-based evidence on family planning (FP) service receipt among women attending health facilities in Ethiopia using nationally implemented Service Provision Assessment (SPA) data. By focusing on FP services delivered during a specific facility visit rather than population-level contraceptive use, the analysis complements household-based evidence and provides insight into service delivery processes occurring during clinical encounters. This distinction is important, as facility-based measures capture whether services are provided during a visit, whereas population-based surveys reflect contraceptive use over time, representing conceptually different outcomes.

A key finding of this study is the inverse association between prior client–provider contact and receipt of FP services during the visit after adjustment for covariates. This contrasts with evidence from population-based studies, where contact with health providers is typically associated with higher contraceptive use [26]. The discrepancy can be explained by differences in outcome definition and timing. In the present study, the outcome reflects service delivery at a single visit rather than cumulative contraceptive behavior.

An important methodological observation in this study was the reversal in direction between the crude and adjusted associations for prior client–provider contact. In unadjusted analysis, women without prior contact had significantly lower odds of receiving FP services during the visit. However, after adjustment for region, facility type, marital status, and other covariates, women without prior contact demonstrated higher adjusted odds of receiving FP services during the visit. The reversal between crude and adjusted estimates suggests that the unadjusted association was strongly confounded by contextual factors, particularly regional and facility-level differences in service delivery patterns. In particular, women with prior contact were disproportionately concentrated within specific regional and facility contexts where the probability of receiving FP services during a given visit differed substantially, thereby altering the conditional association after adjustment.

From a conceptual perspective, prior client–provider contact likely reflects heterogeneous client trajectories rather than a uniform exposure. One possible explanation is that women with prior contact may include returning or continuing users who had previously received counseling or initiated contraception and therefore may have been less likely to require additional FP services during a subsequent visit. In contrast, women with prior contact may represent clients who had previously interacted with FP services and therefore may have been less likely to require additional FP services during the observed visit. This interpretation is consistent with evidence from Ethiopia showing that contraceptive discontinuation and gaps in counseling quality affect how services are used [2730]. Accordingly, the observed association should not be interpreted as a causal effect, as prior contact may proxy unmeasured characteristics such as prior contraceptive use, service experience, or underlying demand for family planning.

The adjusted association observed in this study also highlights the importance of the content and completeness of services delivered during client–provider interactions. Evidence from Ethiopia indicates that many clients do not receive comprehensive counseling, including information on side effects and alternative methods [3134]. Service quality improvements have not necessarily accompanied improvements in contraceptive prevalence [32]. These findings suggest that prior contact alone may not be sufficient to ensure FP service delivery during subsequent facility encounters, emphasizing the need to consider both access and quality dimensions of care. Because the SPA client exit interview captures a single encounter rather than longitudinal service trajectories, temporal ordering between prior contact and current service receipt cannot be fully established. Residual confounding by unmeasured factors, including prior contraceptive history, fertility intentions, and reasons for facility attendance, also cannot be excluded.

Substantial regional variation in FP service receipt was observed after adjustment for individual and facility characteristics. Higher adjusted odds of service receipt in Benishangul-Gumuz, Gambella, and Dire Dawa, and lower odds in Amhara and Addis Ababa, indicate persistent contextual disparities. These findings differ from descriptive distributions, where some regions contributed larger proportions of service recipients, highlighting the importance of adjustment for confounding factors when interpreting regional patterns. The persistence of regional differences after adjustment suggests that unmeasured contextual and health-system factors may influence FP service delivery during facility visits [12,3537]. Although interaction effects were explored to assess potential heterogeneity, unstable estimates due to sparse data limited their interpretability; therefore, regional differences are interpreted at the main-effects level.

Marital status was also associated with service receipt. Married women had lower adjusted odds of receiving FP services during a visit compared with single women, despite representing the majority of clients descriptively. This differs from population-based studies reporting higher contraceptive use among married women [38,39]. This discrepancy is consistent with the distinction between contraceptive use and service receipt at a single visit. One possible explanation is that married women may have differed in prior service experience or reasons for attending the facility, which could influence the likelihood of receiving FP services during a given visit [31].

No statistically significant associations were observed for educational status, number of pregnancies, facility type, provider sex, or place of residence after adjustment. These findings suggest that the study did not identify sufficient evidence of independent associations between these variables and FP service receipt during facility visits within the analyzed sample. However, the absence of statistical significance should be interpreted cautiously because residual confounding, limited variability, or insufficient precision may have influenced these estimates.

Overall, this study contributes to the literature by shifting the focus from population-level contraceptive use to service delivery within health facilities. This perspective reveals how client characteristics, provider interactions, and contextual factors influence whether services are delivered during clinical encounters, offering a more proximal measure of health system performance.

Limitations

Several limitations should be considered when interpreting the findings. First, the cross-sectional design prevents causal inference, necessitating that all reported associations be regarded as non-causal. Second, the outcome variable receipt of a family planning service during the visit combines multiple service components, including counseling and method provision, which may have distinct determinants. Consequently, the results represent the overall service delivery during a visit rather than particular contraceptive behaviors, including initiation, continuation, or sustained use. Third, the facility-based sample includes only women who attended health facilities offering family planning services, which may introduce selection bias and limits generalizability to the broader population, particularly women who do not access facility-based care. Fourth, the analysis may be affected by endogeneity, particularly for prior client–provider contact, which may proxy unobserved characteristics such as prior contraceptive use, service satisfaction, or underlying demand for family planning. Consequently, the observed association should be interpreted with caution. Fifth, although interaction effects were explored to assess potential effect heterogeneity, they were not retained in the final model due to sparse data across subgroups, inflated standard errors, and instability of parameter estimates. Therefore, the main-effects model may not fully capture contextual variation.

Finally, because analyses were conducted without incorporating SPA sampling weights and complex survey design features, findings should primarily be interpreted as associations within the analyzed SPA facility-visit sample rather than nationally representative population estimates.

Conclusions and recommendations

Family planning service receipt during facility visits in Ethiopia is associated with prior client–provider contact, marital status, and regional context. The persistence of regional differences after adjustment suggests that contextual differences in service delivery environments may influence FP service receipt during facility visits.

The findings suggest that the presence of prior contact does not necessarily translate into service delivery at subsequent visits, highlighting the importance of the content and timing of client–provider interactions. In addition, substantial regional variation indicates the need to consider context-specific differences in service delivery environments.

Based on these findings, the following recommendations are proposed:

  • Assess and strengthen the content and completeness of FP-related client–provider interactions, given that prior contact alone was not consistently associated with service receipt during subsequent visits.
  • Implement region-specific strategies to address disparities in service delivery, given the substantial variation observed across regions.
  • Differentiate client pathways (e.g., first-time versus returning clients) within service delivery and monitoring systems to better align services with client needs.
  • Improve measurement of service components in facility-based data systems by distinguishing counseling-only encounters from method provision, given their potentially different determinants observed in this study.
