A fifty-four-year-old retired civil servant in Surulere arrives at the medical out-patient block of one of the major Lagos teaching hospitals at 6:40 in the morning, holding a creased follow-up card from a different consultant clinic that closed eighteen months ago when its principal traveled out, and a pharmacy bag with three weeks left of an antihypertensive she has been on for eleven years. She is in a queue, by 7:15, with eighty-two other people. By two in the afternoon she will have been seen for nine minutes by a third-year senior registrar whose registrar above him will sign her prescription on the way to a ward round, who has not seen her chart before, who will not see her again, and who will write her the same antihypertensive she walked in with at a slightly different dose because the previous prescriber's notes are not legible enough to do anything else. She will leave the building at 4:50. She will return for the same nine minutes in six weeks. She will, in the most accurate clinical reading of her case, have received primary care from a tertiary referral institution because there is no primary care left in the city for her to receive it from.
This is not the failure mode of a teaching hospital. It is the new role of a teaching hospital. The block of patients now passing through the medical out-patient floors of the Lagos University Teaching Hospital, the University College Hospital in Ibadan, the University of Abuja Teaching Hospital, Aminu Kano Teaching Hospital, and the Nnamdi Azikiwe University Teaching Hospital in Nnewi includes, in any honest sampling, between forty and sixty per cent of cases that twenty years ago would never have crossed the threshold of a tertiary institution. They are cases of stable hypertension, uncomplicated Type 2 diabetes, dyslipidaemia, gastro-oesophageal reflux, asthma between exacerbations, anxiety, low back pain, dermatological complaints, paediatric upper-respiratory complaints, contraceptive renewal, and — the largest single category in the audit data — the routine medication refill of patients whose previous prescribing physician is no longer practising in the country.
The teaching hospitals have not absorbed this load because their mandate changed. They have absorbed it because the layer of the system that was supposed to take it does not, by any functional definition, exist any longer.
The shortage is now a different kind of shortage
The arithmetic of the Nigerian doctor shortage is not new. The country produces, by the most generous count of its accredited medical schools, somewhere between three and a half and four thousand new doctors annually. The Medical and Dental Council of Nigeria's registered active-practice numbers have been falling in absolute terms for at least seven years. The General Medical Council in the United Kingdom recorded somewhere over twelve thousand Nigerian-trained doctors on its register as of the most recently published figures, with growth across the last five years that has compounded faster than any other source-country cohort on the register. The Canadian Medical Council, the Australian Medical Board, the Saudi licensing authority, and the Irish Medical Council have, between them, taken several thousand more in the same window. The exit interview data from the largest Lagos teaching hospitals shows a median departure age in the late twenties, a modal subspecialty of general practice and family medicine, and a stated intention to return that, in the longitudinal cohorts that have been tracked, materialises in well under one in ten.
The honest reading of this is not that Nigeria has a doctor shortage. It is that Nigeria has a primary-care shortage of a specific shape, structurally produced by the demographic of the doctor who has been leaving. The consultants in the teaching hospitals — established, fellowship-trained, mid-fifties, with a thirty-year sunk cost in the Nigerian system and households now anchored in it — are not the cohort emigrating. The hospital consultants in the major private centres in Lagos, Abuja, and Port Harcourt are not the cohort emigrating. The cohort emigrating is the cohort that was supposed to become the general practitioner, the family physician, the primary-care consultant, the practice principal, and the small-town clinic owner. That cohort — twenty-eight to thirty-six, post-housemanship, post-NYSC, before the family commitments harden, in possession of a degree that is internationally recognised — is the cohort the recruiting countries are most efficiently extracting, and is the cohort the Nigerian primary-care layer was, before Japa became the verb the country knows it by, structurally dependent on.
The result is not, as the conversation in the press tends to frame it, a country with fewer doctors. It is a country with roughly the same number of senior doctors in roughly the same tertiary institutions, and with the entire generation that was supposed to staff its primary-care floor gone. The shape of the system has changed, not just the count.
What the teaching hospital is now doing
The visible consequence of this is the teaching-hospital out-patient block at 8:15 on any weekday morning. The medical out-patients of UCH, LUTH, UATH, AKTH, and ABUTH are now, in the most honest description of what they are doing, the primary-care floor of the catchment areas they sit in. The blood-pressure recheck, the metformin refill, the routine antenatal review, the contraceptive renewal, and the asthma inhaler prescription that should — in any functional health system, including the one Nigeria had in the early 1980s before the structural-adjustment-era erosion of primary care began — have been managed at a Local Government primary health centre or at a private general practitioner's office is now being managed by a senior registrar at a tertiary institution.
The clinical consequences are predictable. The encounter is short, because the registrar has a list of seventy patients to see. The continuity is absent, because the registrar will rotate off the firm in three months and the patient will see a different registrar in the same chair. The longitudinal record is the patient herself, because the institutional chart is too fragmented to construct a meaningful clinical history from. The titration of chronic-disease pharmacology is approximate, because the registrar does not know the patient and is choosing the safest dose against the worst-case interpretation of her history rather than the optimal dose against an actual baseline. The patient is consequently slightly under-titrated for ten years, with a blood pressure that runs marginally too high and an HbA1c that runs marginally too elevated, until the marginal cumulative excess becomes the cerebrovascular event or the renal decline that brings her back into the same building under a different specialty.
The institutional consequences are more serious. The fellowship-trained consultant whose contracted time is supposed to be teaching, supervising, conducting research, and managing the tertiary case-mix that justifies a tertiary institution is, instead, spending the bulk of his clinic time co-signing prescriptions for primary-care complaints he should not be seeing. The senior registrar whose training trajectory is supposed to expose him to the complex cases that build the next generation of consultants is, instead, spending the bulk of his time managing chronic stable hypertension. The training pipeline of the country's next consultants is being progressively de-skilled at exactly the point in their formation where the exposure matters most, and this is happening at the same teaching hospitals that the country relies on to produce the consultants it is failing to retain. The system is, in this specific structural sense, eating its own seed corn.
What primary care actually is, and why it is hard to rebuild
The temptation in the policy conversation is to treat the primary-care collapse as a recruitment problem to be solved by training more doctors, paying them more, bonding them to service for a fixed period, or filling the gap with task-shifted nurse practitioners. None of these interventions is wrong in isolation. None of them, on the cohort data from the countries that have tried any version of them — Ghana, Kenya, the Philippines, India — is sufficient on its own to rebuild a primary-care layer once it has been structurally hollowed.
The reason is that primary care is not a count of bodies. It is an operating relationship between a population and a continuing clinician, sustained across years, in which the value of the relationship is precisely the accumulated knowledge of the patient that no new clinician can replicate from a file. The hypertensive patient at the top of this piece had been seen by the same physician across nine years, who knew her medication tolerances, her family stressors, her dietary patterns, her work shift, the precise wording her husband used when her oedema worsened, and the rhythm of her clinic attendance well enough to read a missed appointment as a clinical signal rather than as administrative noise. The teaching-hospital registrar who now sees her for nine minutes every six weeks is not a worse doctor than her former physician. He is a doctor without nine years of accumulated knowledge of her, which is the same thing as not being her primary-care doctor at all.
Rebuilding this layer is therefore not a function of training more doctors. It is a function of producing the conditions under which the doctor who has been trained will remain in a sustained relationship with a defined panel of patients across a decade, in the country that trained him, against the gravitational pull of every recruiting country whose income gradient is now an order of magnitude in his favour. This is a policy problem the country has not yet seriously begun to engage with, and it is not a problem the screening practice or the private clinic alone can solve at the population level.
What private practice has had to become in the meantime
What the better Nigerian private practice has done, in the years in which this collapse has been progressing, is build the operating systems that allow a single practice to retain the continuity even when individual clinicians turn over. The clinical record is now built so that the patient's accumulated history sits in the system rather than in the head of the individual doctor. The case-coordinator role — a senior nurse or physician assistant who carries the patient relationship across consultations, prescriptions, and follow-ups — has become the actual continuity layer, with the doctor functioning as the clinical decision-maker against a relationship that the coordinator has been maintaining since the patient registered. The follow-up cadence is calendared in the system rather than left to the patient's memory. The medication reconciliation happens at every visit because the system enforces it rather than because the doctor remembers. The trend on the panel — the HbA1c moving from 5.9 to 6.4 to 6.9 across three years — is read by the system and surfaced to whichever doctor is in the chair on a given Wednesday morning.
None of this replaces the trained primary-care physician at the population level. The point of describing it is the opposite — it is the adaptation the best private practices have made to the country in which the trained primary-care physician at the population level no longer reliably exists. The continuity has been moved off the doctor and onto the system, because the doctor can no longer be guaranteed to remain in the chair for the nine years across which a useful clinical relationship matures.
The patient whose access to this kind of system is a function of her ability to pay for it has not had her access to continuity restored. The honest distributional reading of where private practice is now is that the patient who can afford the coordinator-led, systematised, continuity-preserving model has continuity, and the patient who cannot — the patient at the top of this piece — is in the teaching-hospital queue at 7:15 on a Tuesday morning, where the structural inability of the system to preserve any clinical thread across two visits is no longer the failure mode it used to be, but the operating reality of the institution she is queueing for.
The honest close
The conversation about Japa in the Nigerian press tends, understandably, to be a conversation about ambition, opportunity, household choice, and the pull factors of the recruiting countries. The conversation is real. The country that is left, however, has not yet developed the language to describe what the wave has done to the layer of its medical system that was most structurally dependent on the cohort that left. The shortage is not the shortage the headline number describes. It is the precise, demographic, primary-care-shaped collapse that puts the stable hypertensive of Surulere in a teaching-hospital corridor for ten hours on a Tuesday — not because her case is complicated, but because the floor of the system she was supposed to live on has been quietly removed underneath her, and the only floor she can still reach is the one above it, which was never built to hold her weight.
The serious version of the conversation, in the practice's reading, begins from this point rather than from the one the policy debate currently begins from. It accepts that the primary-care physician is not coming back in the volumes the population needs in the timeframe the population needs him. It accepts that the teaching hospitals will continue, for at least a generation, to be functioning as primary-care floors against a tertiary establishment cost structure that the country cannot sustain. It accepts that the continuity layer has, in the part of the system that can pay for it, moved from the individual physician onto the operating system of the practice — and that this is a useful adaptation rather than a regrettable second best. And it accepts that the patient whose access to that adaptation depends on her ability to pay for it is, in any honest reading of where the country has arrived, the centre of the policy question the country has not yet started to ask.
Primary care in Nigeria has not failed because Nigerian doctors are not capable. It has failed because the cohort that staffs it has, in the demographically specific way that the recruiting countries have produced, traveled out. The work of rebuilding it has not started. The work of describing what has happened in its absence has barely started. The patient in the teaching-hospital corridor is, until either of those changes, the system as it currently is.
