Instructions
Each group receives one scenario. Work through all tasks in sequence — read the clinical and epidemiological context carefully before beginning the calculations. Show all working. For discussion and interpretive questions, prepare a concise answer of 3–5 sentences that the group will present to the class. The cross-group synthesis question at the end is addressed jointly.
Reference Material
This assignment is based on the reading material: Reproductive Health, Family Medicine, and Adolescent Health. All answers and justifications must reference the concepts established in this text.
Scenario 1 — Reproductive Health and Abortion in a Primary Care Practice, Plovdiv
Context
Dr. Milena Georgieva is a general practitioner at an outpatient clinic in the Stolipinovo district of Plovdiv, an urban area with a young demographic profile, low average educational attainment, and documented barriers to reproductive health services. Her practice list includes 2,340 registered patients, of whom 580 are women aged 15–49 years. In 2025, her practice records show the following reproductive health data:
- 34 deliveries
- 18 induced (elective) abortions
- 6 spontaneous abortions (miscarriages)
- 4 therapeutic terminations of pregnancy
- 3 cases of newly diagnosed infertility (couples referred for specialist evaluation)
- 14 newly initiated modern contraceptive methods (hormonal or intrauterine)
The district’s population of women aged 15–49 is estimated at 7,200. The total number of live births in the district in 2025 was 410.
Task 1.1. Calculate the abortion ratio for Dr. Georgieva’s practice population, defined as the number of induced abortions per 100 live births.
\[\text{Abortion ratio} = \frac{\text{Induced abortions}}{\text{Live births}} \times 100 = \frac{18}{34} \times 100 = 52.9 \text{ abortions per 100 live births}\]
This figure substantially exceeds the European Union average, which in most member states ranges from approximately 15 to 30 per 100 live births. A ratio approaching 53 per 100 live births indicates that induced abortion is functioning as a primary fertility regulation measure rather than a secondary one — a pattern historically characteristic of Bulgaria and particularly pronounced in populations with limited contraceptive access and low reproductive health literacy.
Task 1.2. Calculate the contraceptive coverage rate in the practice, defined as newly initiated modern contraceptive methods per 100 women of reproductive age registered in the practice.
\[\text{Contraceptive coverage (new initiations)} = \frac{14}{580} \times 100 = 2.4\%\]
This represents newly initiated methods during one calendar year, not the prevalence of current contraceptive use among all women of reproductive age — which would require a cross-sectional survey. Even so, 2.4 new initiations per 100 women is low and consistent with the high abortion ratio observed in Task 1.1. The two indicators together paint a coherent epidemiological picture of insufficient uptake of modern contraception within this population.
Task 1.3. Dr. Georgieva is aware that abortion during a first pregnancy carries an estimated risk of secondary sterility of approximately 21–22%. Of the 18 induced abortions recorded, 7 were in nulliparous women. Estimate the expected number of these women who may develop secondary sterility attributable to this abortion.
\[\text{Expected cases of sterility} = 7 \times 0.215 = 1.5 \approx 1\text{–}2 \text{ women}\]
Using the midpoint of the 21–22% range: 7 × 0.215 = 1.5 cases. With a 95% uncertainty range based on the published figures, between 1 and 2 of these nulliparous women may subsequently experience infertility attributable to this procedure. This calculation has important counselling implications: the risk is not negligible on a population scale, and post-abortion contraceptive counselling is both a clinical imperative and a preventive intervention against secondary infertility.
Discussion Question. Dr. Georgieva wishes to reduce the abortion ratio in her practice. Drawing on the reading material and your understanding of the Bulgarian reproductive health context, identify the two most important interventions she should prioritise — one at the individual patient level and one at the community or system level. Explain the rationale for each.
At the individual level, the most important intervention is systematic post-abortion contraceptive counselling and immediate provision of modern contraception at the point of abortion care or at the earliest post-abortion contact. The period immediately after an abortion is a critical window: the woman has direct experience of an unintended pregnancy, motivation to prevent recurrence may be elevated, and the biological opportunity to initiate hormonal contraception or insert an intrauterine device is optimal. This intervention is a mandatory clinical responsibility under Bulgarian reproductive health standards and is cost-effective relative to the downstream consequences of repeat abortion.
At the community or system level, the priority is expanding access to and uptake of long-acting reversible contraception (intrauterine devices, hormonal implants) within the district, particularly through outreach to younger women and those with limited health literacy. This may require collaboration with social workers, community mediators in Roma communities, and NGOs, as well as GP-level provision rather than specialist-only prescribing. Structural barriers — cost, geographic access, cultural attitudes — are the primary drivers of the pattern observed, and no counselling intervention alone will be sufficient without addressing these upstream determinants.
Scenario 2 — Family Health Assessment and Problem Family Classification, Ruse
Context
Dr. Stefan Varbanov is a general practitioner at a group practice in Ruse. During a home visit and subsequent consultations, he obtains the following information about four families on his practice list. He must assess each family’s structure, classify it according to problem family typology, and plan appropriate follow-up.
Family A. A 28-year-old woman, recently separated from her partner of five years (the relationship was never legally registered). She has two children aged 2 and 4. She works part-time as a shop assistant. Her former partner does not contribute financially and has irregular contact with the children. She reports difficulty managing all childcare responsibilities alongside work, is frequently exhausted, and has missed two scheduled health visits for the younger child over the past six months.
Family B. A married couple aged 68 and 71, both pensioners. Their son, aged 42, was diagnosed with advanced colorectal cancer three months ago and has recently commenced palliative chemotherapy. He lives with them. The wife provides most of the direct care, including medication management and accompanying him to hospital appointments. She herself has controlled hypertension and mild osteoarthritis. The husband has type 2 diabetes and limited mobility. The son has begun to develop pain that is inadequately controlled on current analgesia.
Family C. A divorced father aged 38 who has sole legal custody of his daughter aged 9 following divorce two years ago. The mother has occasional supervised contact. The father reports that his daughter has recently become increasingly anxious, is refusing to attend school, and has started wetting the bed again — a behaviour that had resolved at age 5. The father works shifts as a factory supervisor. He describes sustained conflict with his former wife, who contests the custody arrangement through ongoing court proceedings.
Family D. A cohabiting couple, both aged 23, with an 8-month-old infant. They are not legally married and share a rented apartment. The partner of the registered mother is not the biological father and has not been legally established as the child’s parent. The infant’s biological father is unknown. The infant has received the BCG vaccine at birth but no subsequent immunisations. The mother reports she did not know she needed to register the child with a GP and was unaware that the child health programme entailed scheduled vaccination visits.
Task 2.1. For each family, identify the primary problem family typology category and name at least one specific health risk associated with that type.
Family A is a single-parent family. The primary health risks include parental burnout — sole caregivers carry the full load of employment and childcare without relief — elevated perinatal risk if a future pregnancy occurs, and reduced preventive care attendance, already evidenced by two missed child health visits. The children face developmental surveillance gaps and possible nutritional or psychosocial risks associated with financial hardship.
Family B is a family with a terminally ill member. The primary health risks include caregiver burden: the wife (who has her own chronic conditions) and the husband (who has diabetes and limited mobility) are providing intensive care without adequate external support. The patient has undertreated pain, which is a patient safety and palliative care quality concern. The caregiving couple are themselves at elevated risk for exhaustion, deterioration in chronic disease control, depression, and isolation.
Family C is a post-divorce family. The primary health risk is child exposure to sustained interparental conflict, which is a well-documented risk factor for anxiety, depressive symptoms, somatic complaints, and regressive behaviours in children — all of which are already manifest in the daughter. The father is at risk for burnout managing solo parenting, shift work, and ongoing legal proceedings simultaneously.
Family D is a cohabiting (concubine) family with a legal ambiguity concerning the infant’s parentage. The primary health risk is missed immunisation: the infant has received only the birth BCG and is now eight months old with no subsequent vaccines in the national schedule. This represents a direct infection risk to the child and a broader herd immunity gap. The legal non-recognition of the partner creates insurance and consent complexities if the mother is unavailable.
Task 2.2. For Family B, Dr. Varbanov must prioritise his immediate clinical actions. List them in order of urgency and explain the rationale for your ordering.
The most urgent action is pain assessment and analgesia review for the son. Inadequate pain control in a patient receiving palliative care is a clinical emergency by the standards of palliative medicine: it causes unnecessary suffering, disrupts sleep and nutrition, and undermines the patient’s and family’s quality of life during a terminal phase. Dr. Varbanov should either adjust the analgesia prescription within his competence or arrange urgent referral to the oncology or palliative care team the same day.
Second in priority is health assessment of the wife as primary caregiver. She has her own chronic conditions and is providing intensive care. Her blood pressure should be reviewed, her medication adherence checked, and she should be screened for depression and burnout using a validated instrument. Caregiver collapse in this context would simultaneously worsen outcomes for the patient and eliminate the primary care resource sustaining him at home.
Third, Dr. Varbanov should initiate coordination of palliative support services — liaison with a palliative care team, social worker, and where available, a home care nurse — to reduce the physical and organisational burden on the elderly caregivers. Referral for psychological support for all three family members, including anticipatory grief counselling, should be arranged concurrently.
Discussion Question. Consider Family D from the perspective of the Bulgarian National Immunisation Programme. What are the GP’s obligations regarding the 8-month-old infant, and what barriers — structural, legal, and behavioural — might complicate the catch-up process? Propose one concrete step Dr. Varbanov can take at this consultation to begin addressing each barrier.
The GP has an obligation to register the infant in the practice child health programme and immediately initiate a catch-up immunisation schedule under current NHIF guidelines, which provide for catch-up vaccination of unvaccinated or incompletely vaccinated children. The child’s legal parentage does not preclude medical care: the registered mother has parental authority and can consent.
Structural barriers include the family’s lack of awareness that registration was required and that scheduled visits carry specific clinical content. The GP can address this at the consultation by providing written information about the child health programme schedule and the specific vaccines now overdue.
Legal barriers include uncertainty about insurance coverage and consent for procedures if the biological father’s identity is unestablished. The GP can consult the practice’s administrative staff and, if necessary, clarify with the NHIF regional office that the child’s entitlement to the national immunisation programme is unconditional and does not depend on paternity establishment.
Behavioural barriers relate to health literacy and trust. The mother was not negligent — she did not know what was expected. A non-judgmental, information-focused approach at this consultation is more likely to secure engagement with the catch-up schedule than a corrective one. Booking the first catch-up appointment before the mother leaves the clinic is the single most effective step.
Scenario 3 — Adolescent Health, Acceleration, and Substance Use, Montana
Context
Dr. Yordanka Tsvetkova is a school physician at a secondary school in Montana, a town in north-western Bulgaria with a population of approximately 23,000. The school has 620 students aged 14–18 years. She conducts an annual health survey. In 2025, the survey returns the following findings:
- 312 students (50.3%) report current alcohol consumption (at least once in the preceding 30 days)
- 118 students (19.0%) report heavy episodic drinking (≥60 g pure alcohol on at least one occasion in the preceding 30 days)
- 148 students (23.9%) report current e-cigarette use
- 64 students (10.3%) report ever having used cannabis
- Mean systolic blood pressure in the 16–18 age group (n = 290): 128.4 mm Hg (SD 11.6)
- 12 students have been referred to a cardiologist in the current academic year for elevated blood pressure on repeat measurement
- BMI ≥ 25 kg/m²: 31% of students; BMI ≥ 30 kg/m²: 11% of students
- 3 female students aged 15–16 disclosed a pregnancy to Dr. Tsvetkova during the year
Task 3.1. Compare the school’s alcohol and e-cigarette prevalence figures with the Bulgarian national adolescent reference data given in the reading material (alcohol current use 50.2%; heavy episodic drinking 20.2%; e-cigarette use 23.3% in adolescents aged 13–15). Interpret the comparison — is the school population typical, better, or worse than the national reference, and what caution is warranted in this comparison?
| Indicator | School (14–18 years) | National reference (13–15 years) | Direction |
|---|---|---|---|
| Current alcohol use | 50.3% | 50.2% | Essentially identical |
| Heavy episodic drinking | 19.0% | 20.2% | Marginally better |
| E-cigarette use | 23.9% | 23.3% | Marginally worse |
The school population appears broadly typical of the national profile. The proportions are strikingly close to the national reference values for all three indicators.
The key methodological caution is that the national reference comes from the 13–15 age group (WHO data), while the school survey covers 14–18 year olds. Older adolescents would generally be expected to show higher substance use prevalence than younger ones. If the school’s 14–18 age group shows prevalence similar to the national 13–15 benchmark, the school population may actually be doing somewhat better than a true age-matched comparison would show. Alternatively, the survey methodology, response rate, and social desirability bias may differ between the national survey and the school-level instrument — a limitation that should be acknowledged in any formal report.
Task 3.2. Among the 290 students aged 16–18, the mean systolic blood pressure is 128.4 mm Hg. Using standard diagnostic thresholds for adolescent hypertension (systolic blood pressure ≥ 130 mm Hg), and assuming a normal distribution of SBP values in this group, estimate the proportion of students who may have systolic BP at or above the threshold. Use the z-score approach.
\[z = \frac{130 - 128.4}{11.6} = \frac{1.6}{11.6} = 0.138\]
Using a standard normal table, P(Z > 0.138) ≈ 0.445.
Therefore approximately 44.5% of students aged 16–18 have a systolic blood pressure at or above 130 mm Hg on the survey measurement.
This is a cross-sectional single measurement and does not constitute a clinical diagnosis of hypertension — which requires elevated readings on at least two separate occasions. The finding does, however, indicate that a substantial proportion of this adolescent cohort warrants repeat measurement and clinical follow-up. This is consistent with the broader phenomenon of “rejuvenation” of cardiovascular risk factors described in the context of biological acceleration and the obesity epidemic: BMI ≥ 25 kg/m² in 31% of the school population provides a plausible explanatory pathway.
Task 3.3. Three female students aged 15–16 disclosed pregnancies to Dr. Tsvetkova. Connecting this observation to the concept of acceleration and social infantilism, explain in no more than five sentences why early sexual maturation may increase rather than decrease reproductive health risk in this age group. Do not repeat the definition of social infantilism — provide the mechanistic argument.
Early biological maturation grants adolescents reproductive capacity before the development of the cognitive and emotional competencies — impulse control, planning horizon, negotiation in intimate relationships — that effective contraceptive use demands. A 14-year-old who has undergone pubertal development comparable to a 17-year-old is perceived by peers and older contacts as socially older, gaining access to social contexts where sexual activity and alcohol are normative before she has the judgement to navigate them protectively. The evidence consistently shows that earlier pubertal timing is associated with earlier onset of sexual activity but not with higher rates of contraceptive use — the biological drive advances but the protective behaviour does not follow automatically. Bulgaria’s position as the country with the highest proportion in Europe of mothers under 15 years of age is the population-level expression of this individual-level mechanism. The implication for prevention is that sexual education must be delivered before, not after, biological maturation begins, and must focus on negotiation skills and contraceptive knowledge rather than on biological information that early-maturing adolescents may already possess.
Discussion Question. Dr. Tsvetkova is preparing a short report for the school principal on the survey findings, to be shared with the school governing board. The principal has asked her to include a recommendation about implementing sexual education in the curriculum. The school currently has no structured programme. Drawing on the evidence discussed in the reading material, what single recommendation — with its evidence base stated — would you advise Dr. Tsvetkova to make?
The recommendation should be to implement a comprehensive, evidence-based sexual education programme that integrates biological information with psychological skill-building, values clarification, and content on human rights and gender equality — as opposed to an abstinence-only or purely biological approach. The evidence base is unambiguous: abstinence-only education has been shown in systematic reviews to be entirely ineffective in delaying sexual initiation, does not reduce rates of unintended pregnancy or sexually transmitted infection, and may cause harm by marginalising young people and perpetuating harmful gender norms. Comprehensive sexual education, by contrast, equips adolescents with the communication and negotiation skills to use contraception correctly, decline unwanted sexual contact, and seek appropriate care — thereby addressing the mechanistic pathway, identified in Task 3.3, through which acceleration increases reproductive health risk. Given the survey finding of three pregnancies in 15–16 year olds in a single academic year in a school of 620 students, the burden of inaction is demonstrably not zero.
Scenario 4 — Neonatal Screening, Congenital Disease Prophylaxis, and Adopted Children, Stara Zagora
Context
Dr. Petya Hristova is a paediatrician at a regional paediatric outpatient clinic in Stara Zagora. Over one month she sees the following four patients, each presenting a distinct aspect of the prophylaxis of congenital diseases or the health needs of children in non-standard family situations.
Patient A. A 6-day-old neonate, born at term, birth weight 3,220 g, Apgar scores 9/10. The mother was informed before discharge that the heel-prick blood spot was collected, but she was not told what conditions it tests for. She attends the clinic to collect the result and asks Dr. Hristova to explain the programme.
Patient B. A 3-year-old boy adopted from a residential care institution in Sofia eight months ago by a couple in Stara Zagora. His new parents report that he has had four episodes of acute otitis media in the past six months, his speech is delayed (he uses approximately 40 words, compared with an expected 200–300 at age three), he has dental caries in five deciduous teeth, and his growth is at the 3rd percentile for height. A review of the institutional records provided at adoption shows that his BCG, hepatitis B, and pentavalent (DTaP-IPV-Hib) series are documented but without batch numbers, and his MMR vaccination is not recorded.
Patient C. A 16-year-old female referred from her GP after a first-trimester combined screening result showing a risk of 1:85 for trisomy 21 (using a local laboratory). She is now 13 weeks gestation. The referring GP has offered no further explanation and the patient and her mother are distressed and uncertain about what the number means and what options are available.
Patient D. A 14-year-old boy who has been known to the clinic since age 7 with Duchenne muscular dystrophy. He uses a powered wheelchair, has forced vital capacity of 52% predicted, and is under shared care with the neuromuscular disease centre in Sofia. His parents ask whether any genetic testing should be performed on the younger sister, aged 9, to determine whether she is a carrier.
Task 4.1. Dr. Hristova explains the Bulgarian national neonatal screening programme to the mother of Patient A. List the four conditions included in the current programme, specify what clinical outcome is prevented by early detection of each, and identify which of the four is the most common preventable cause of intellectual disability.
| Condition | Mechanism of harm if untreated | Outcome prevented by early detection |
|---|---|---|
| Phenylketonuria (PKU) | Accumulation of phenylalanine causes progressive neurotoxicity | Intellectual disability; prevented by early dietary phenylalanine restriction |
| Congenital hypothyroidism | Thyroid hormone deficiency impairs brain maturation in the neonatal period | Intellectual disability and growth failure; prevented by early levothyroxine replacement |
| Congenital adrenal hyperplasia (CAH) | Cortisol and aldosterone deficiency causes life-threatening salt-wasting crisis | Neonatal death from adrenal crisis; prevented by early corticosteroid replacement |
| Cystic fibrosis | Progressive lung damage from viscous secretions and recurrent infection | Severe pulmonary morbidity; early treatment substantially improves long-term prognosis |
Congenital hypothyroidism is the most common preventable cause of intellectual disability among the four. It occurs in approximately 1 in 2,000–4,000 live births and is entirely preventable with early levothyroxine supplementation commenced in the first weeks of life.
In addition to the metabolic screen, Dr. Hristova should inform the mother that the universal programme also includes neonatal hearing screening (to protect early speech and language development) and pulse oximetry for critical congenital heart disease before hospital discharge — two components delivered during the birth admission rather than through the blood spot.
Task 4.2. For Patient B, Dr. Hristova must address the immunisation records and plan catch-up vaccination. The MMR vaccine is not documented. The child is now 3 years and 8 months old. Under the Bulgarian national immunisation schedule, at what age is the first MMR dose normally administered? Is the child overdue? What is the appropriate clinical decision regarding MMR vaccination, and what risk does the current gap represent?
Under the Bulgarian national immunisation schedule, the first dose of MMR (measles-mumps-rubella) vaccine is administered at 13 months of age. The child is now 3 years and 8 months old with no documented MMR vaccination — he is therefore approximately 31 months overdue for his first dose.
The appropriate clinical decision is to administer MMR immediately (first dose) and schedule the second dose according to the catch-up schedule, typically with a minimum interval of four weeks between doses. The absence of documentation of institutional vaccinations is a common problem in children adopted from residential care in Bulgaria, where record-keeping quality varies substantially. When batch numbers are absent, immunogenicity cannot be verified, and re-administration of the series is generally preferable to serological testing in a young child — though clinical judgement and specialist guidance should inform the decision for each antigen.
The current gap represents a direct risk of measles infection, a disease that causes severe encephalitis, pneumonia, and death in unvaccinated children, and that circulates periodically in Europe due to accumulated under-vaccination. The child’s attendance at nursery or kindergarten amplifies both his personal risk and the risk he poses to other unvaccinated contacts. Prompt catch-up is therefore both an individual clinical priority and a public health obligation.
Task 4.3. Patient C has a combined screening risk of 1:85 for trisomy 21 at 13 weeks of gestation. Interpret this probability for a clinical explanation to the patient and her mother. Then distinguish between the two available pathways — non-invasive prenatal testing (NIPT) and invasive diagnostic testing (amniocentesis or chorionic villus sampling) — specifying for each the approximate detection rate for trisomy 21, the procedure-related risk, and the type of result it provides.
A risk of 1:85 means that, among 85 pregnancies with this screening result, approximately one fetus will have trisomy 21 and 84 will not. Expressed as a probability, this is approximately 1.2%. Combined screening classifies this as high risk (the standard threshold used in most European centres is 1:250 or 1:300). It is important to explain clearly to the patient and her mother that a high-risk result is not a diagnosis — it indicates that further testing is appropriate, not that the fetus has Down syndrome.
| Pathway | Detection rate for trisomy 21 | Procedure-related risk | Type of result |
|---|---|---|---|
| NIPT (cell-free fetal DNA from maternal plasma) | >99% with very low false-positive rate | None (maternal blood sample only) | Screening result — high or low probability; requires confirmatory invasive testing if positive |
| CVS (chorionic villus sampling, 11–14 weeks) | 100% (diagnostic) | Approximately 0.5–1% procedure-related pregnancy loss | Definitive diagnosis — full karyotype |
| Amniocentesis (15–20 weeks) | 100% (diagnostic) | Approximately 0.1–0.5% procedure-related pregnancy loss | Definitive diagnosis — full karyotype |
At 13 weeks, both CVS (still within the gestational window) and NIPT are available options. The patient should be referred without delay to a fetal medicine or prenatal genetics unit for counselling and, if she chooses invasive testing, the window for CVS is closing rapidly. Dr. Hristova should document the referral as urgent.
Discussion Question. The parents of Patient D (Duchenne muscular dystrophy) ask about genetic testing for the 9-year-old sister to determine carrier status. This request raises a specific ethical tension in paediatric genetics. Identify the tension, state the principle that governs clinical decision-making in this situation, and explain what Dr. Hristova should do — and not do — at this consultation.
The ethical tension is between the parents’ understandable wish to know whether their daughter carries the DMD mutation — which has implications for her own future reproductive decisions — and the child’s right to make this decision herself when she reaches an age of sufficient maturity and autonomous consent. Carrier testing in a 9-year-old girl for a condition that will not affect her health during childhood but that will affect her reproductive options in adulthood is a paradigmatic case in paediatric clinical genetics: the result, once known, cannot be unknown, and the child herself has no voice in whether she wants this knowledge.
The governing principle is that predictive genetic testing in minors is generally deferred until the child can participate meaningfully in the decision, unless an earlier result would directly benefit the child’s own health management — which is not the case for a DMD carrier. This principle is reflected in international consensus guidance from organisations including the European Society of Human Genetics.
Dr. Hristova should acknowledge the parents’ concern fully and without dismissiveness, explain why the timing of testing is an ethically significant question rather than a purely technical one, and arrange referral to a clinical geneticist who can conduct formal genetic counselling for the family. She should not order carrier testing at this consultation, and she should not suggest that the test is straightforwardly indicated. The consultation is an opportunity to introduce the concept of the child’s future autonomous right to genetic knowledge — a right that becomes unconditional when genetic matching is required for procedures such as organ transplantation.
Cross-Group Synthesis Question
The four scenarios in this class have addressed reproductive health in a primary care population, family typology and physician response, adolescent health in a school setting, and neonatal and prenatal screening. A common thread connects them: the relationship between social vulnerability, access to preventive care, and the concentration of health risk.
Drawing on all four scenarios, answer the following question as a class:
Which single public health intervention — applicable across the domains of maternal health, family care, adolescent health, and congenital disease prophylaxis — would produce the greatest reduction in the disease burden described in today’s scenarios? Justify your choice with evidence from at least three of the four scenario contexts, and identify the level of the health system at which the intervention must be primarily delivered.
There is no single correct answer. The group that presents the most persuasive, evidence-grounded argument wins the discussion.
